Patients with Philadelphia chromosome–positive acute lymphoblastic or chronic myeloid leukemias in lymphoid blast phase may have longer event-free and overall survival with a combination of inotuzumab ozogamicin (Besponsa) and bosutinib (Bosulif) than with standard chemotherapy combined with a targeted agent, investigators in a phase 1/2 study reported.

Among patients with relapsed or refractory Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) or chronic myeloid leukemia (Ph+ CML) in lymphoid blast phase treated with inotuzumab ozogamicin (Besponsa) and bosutinib (Bosulif), the median overall survival was 15.4 months. In contrast, median overall survival for similar patients treated with chemotherapy and a tyrosine kinase inhibitor (TKI) was less than 6 months, reported Nitin Jain, MD, and colleagues from the University of Texas MD Anderson Cancer Center in Houston.

The study was presented in a scientific poster session as part of the virtual annual congress of the European Hematology Association.

“Patients with relapsed/refractory Philadelphia chromosome–positive ALL/CML in lymphoid blast crisis are also best managed with a TKI targeting the constitutively active ABL kinase with the TKI selected based on presence of ABL kinase mutations and prior TKI history,” commented Marlise R. Luskin, MD, a leukemia specialist at the Dana-Farber Cancer Institute in Boston.

“A critical question for this patient population is whether these two approaches [TKI and inotuzumab ozogamicin] can be administered safely in combination. I congratulate MD Anderson for completion of this Phase I trial which demonstrates that inotuzumab and bosutinib can be safely combined with identification of a maximum tolerated dose of bosutinib 400 mg daily when administered in combination. I look forward to further studies that explore the efficacy of combination versus the approved single-agent regimen,” she said in an interview.
 

Study details

To see whether they could improve the dismal outcomes for patients with Ph+ ALL or Ph+ CML in lymphoid blast phase, they studied the combination of inotuzumab ozogamicin, an anti-CD22 monoclonal antibody conjugated to the cytotoxic antibiotic calicheamicin, and bosutinib, an inhibitor of the ABL kinase. Inotuzumab is approved in the United States for treatment of adults with relapsed or refractory B-cell precursor ALL, bosutinib is approved for the treatment of patients with newly-diagnosed chronic phase Ph+ CML and for adults with chronic, accelerated, or blast phase Ph+ CML with resistance or intolerance to prior therapy.

The investigators enrolled 16 patients with Ph+ ALL and 2 with Ph+ CML with bone marrow blasts greater than 5%, CD22 expressed on at least 20% of blasts, and good to fair performance status. The patients also had adequate organ function as measured by liver enzyme, total bilirubin, and serum creatinine levels. Patients with the T315I mutation, prior anti-CD22 therapy, active graft-versus-host disease, or liver disease were excluded.

The patients received inotuzumab 0.8 mg/m² intravenously on day 1, they received 0.5 mg/m² on days 8 and 15 of cycle 1, and they received 0.5 mg/m² on days 1, 8, and 15 of cycles 2 through 6. Each cycle was 4 weeks. Patients who had a complete remission (CR), had complete cytogenetic remission (CCyR), or became negative for minimal residual disease (MRD) continued on 1 mg/m² every 4 weeks. Bosutinib was dosed continuously day starting on the first day of cycle 1 and continued until disease progression or toxicity.

After a median follow-up of 36.7 months, 11 of the 18 patients had CRs, and 4 had CRs with incomplete recovery of hematologic counts. In addition, 13 of 16 patients with without diploid cytogenetics at the start of the study had CCyr; 14 patients had major molecular remission; 10 had complete molecular remission, and 11 were negative by flow cytometry.

As noted before, the median overall survival was 15.4 months. Event-free survival – time to lack of response, relapse, MRD relapse requiring therapy, or death – was 8 months. The event-free survival data were not censored for allogeneic stem cell transplant. Six patients underwent transplant while in remission.

The primary objective of the phase 1 trial was to evaluate safety of the combination and determine the maximum tolerated dose of bosutinib, which was determined to be 400 mg daily. At this dose level, one patient had a dose-limiting toxicity in the form of a grade 3 skin rash.

The most frequent adverse events were diarrhea and rash, in 50% of patients each, and nausea in 39% of patients. Grade 3 adverse events included were rash in three patients and reversible alanine aminotransferase and hyponatremia in one patient each. No patients developed veno-occlusive disease, and there no deaths within 30 days of the start of therapy.

Dr. Jain disclosed consultancy, honoraria, advisory board/committee activity, and research funding from Pfizer, maker of inotuzumab ozogamicin and bosutinib. Dr. Luskin reported no relevant disclosures.

Here are the stories our MDedge editors across specialties think you need to know about today:

Pregnant women at higher risk for severe COVID-19

Pregnant women may be at increased risk for severe COVID-19 illness, according to a report published online June 26 in Morbidity and Mortality Weekly Report.

Among reproductive-aged women (15-44 years) infected with SARS-CoV-2, pregnancy was associated with a greater likelihood of hospitalization, admission to the intensive care unit (ICU), and mechanical ventilation, but not death. Pregnant women were 5.4 times more likely to be hospitalized, 1.5 times more likely to be admitted to the ICU, and 1.7 times more likely to need mechanical ventilation, after adjustment for age, underlying conditions, and race/ethnicity.  

CDC researchers said that preventing COVID-19 infection in pregnant women should be a priority and any potential barriers to compliance with preventive measures need to be removed.

“During pregnancy, women experience immunologic and physiologic changes that could increase their risk for more severe illness from respiratory infections,” they wrote. Read more.

Going out of business: Primary care practices at risk

In a recently published editorial, Tom Frieden, MD, MPH, former head of the Centers for Disease Control and Prevention, argued that primary care is in deep trouble, its long-standing financial problems exacerbated by the fallout from the COVID-19 pandemic. In an interview with Kenny Lin, MD, MPH, a family physician, Dr. Frieden discussed the future of primary care.

Here is a sample of Dr. Frieden’s observations:

“When I’ve looked around the United States, I’ve been extremely concerned about both the risk that primary care practitioners are subjected to in their everyday practice and the economic risk that we could lose many of our primary care practices around the country. It’s really striking to see that the number of visits has plummeted. Because of our payment structure, that means incomes have plummeted. We’re hearing about doctors’ offices getting boarded up and shuttering. As I write in the piece, it’s one thing for a theater or a restaurant or another important community entity to shut because of economic downturn, and these are real losses, but to lose their only primary care practice or one of the few in an area really is a matter of life and death for many communities.” Read more.
 

Surge in out-of-hospital cardiac arrests

The COVID-19 pandemic in New York City led to a surge in out-of-hospital cardiac arrests that placed a huge burden on first responders, according to a new analysis.

During the height of the pandemic in New York, there was a “dramatic increase in cardiopulmonary arrests, nearly all presented in non-shockable cardiac rhythms (> 90% fatality rate) and vulnerable patient populations were most affected,” David J. Prezant, MD, chief medical officer, Fire Department of New York (FDNY), said in an interview.

In a news release, Dr. Prezant noted that “relatively few, if any, patients were tested to confirm the presence of COVID-19,” making it impossible to distinguish between cardiac arrests as a result of COVID-19 and those that may have resulted from other health conditions.

“We also can’t rule out the possibility that some people may have died from delays in seeking or receiving treatment for non–COVID-19-related conditions. However, the dramatic increase in cardiac arrests compared to the same period in 2019 strongly indicates that the pandemic was directly or indirectly responsible for that surge in cardiac arrests and deaths,” said Dr. Prezant.

The study was published online June 19 in JAMA Cardiology.

Fenfluramine approved for Dravet syndrome

The U.S. Food and Drug Administration has approved fenfluramine (Fintepla, Zogenix) oral solution, a Schedule IV controlled substance, for the treatment of seizures associated with Dravet syndrome in children age 2 years and older.

Dravet syndrome is a rare childhood-onset epilepsy characterized by frequent, drug-resistant convulsive seizures that may contribute to intellectual disability and impairments in motor control, behavior, and cognition, as well as an increased risk of sudden unexpected death in epilepsy.

Dravet syndrome takes a “tremendous toll on both patients and their families. Fintepla offers an additional effective treatment option for the treatment of seizures associated with Dravet syndrome,” Billy Dunn, MD, director, Office of Neuroscience in the FDA’s Center for Drug Evaluation and Research, said in a news release.

The use of CPX-351, a dual-drug liposomal encapsulation of cytarabine and daunorubicin, was tied to long-term remission and survival in older patients with newly diagnosed high-risk or secondary acute myeloid leukemia (AML), according to final results of a phase 3 study.

As part of the American Society of Clinical Oncology virtual scientific program, Jeffrey E. Lancet, MD, of the Moffitt Cancer Center in Tampa, Fla., presented the 5-year final data from a trial comparing CPX-351 vs. the conventional 7+3 regimen of cytarabine and daunorubicin in more than 300 older adult patients (age 60-75 years) with newly diagnosed high-risk or secondary AML. Early mortality rates for CPX-351 vs. 7+3 were 6% vs. 11% at Day 30 and 14% vs. 21% at day 60, respectively.

The final 5-year follow-up results had a median follow-up of just greater than 60 months, and maintained the improved median overall survival previously observed in the trial with CPX-351 (153 patients), compared with 7+3 (155 patients), Dr. Lancet reported.

Allogeneic hematopoietic stem cell transplant was received by 35% of the patients in the CPX-351 arm and 25% of patients in the 7+3 arm. The median overall survival after transplant was not reached for the CPX-351 arm, compared with 10.3 months with the 7+3 treated patients.

Remission, either complete remission or complete remission with incomplete neutrophil or platelet recovery, was achieved by 48% of patients in the CPX-351 arm and 33% of patients in the 7+3 arm, according to the results of the 5-year follow-up. In addition, among all patients who achieved remission, median overall survival was longer with CPX-351 than with 7+3, and the Kaplan-Meier estimated survival rate was higher for CPX-351 at both 3 years and 5 years.

At 5 years of follow-up, 81% of patients in the CPX-351 arm and 93% of patients in the 7+3 arm had died, with similar causes cited in each arm. Progressive leukemia was the most common primary cause of death in both treatment arms, according to Dr. Lancet.

“The final 5-year follow-up results from this phase 3 study support the prior evidence that CPX-351 has the ability to produce or contribute to long-term remission and survival in older patients with newly diagnosed high-risk or secondary AML,” Dr. Lancet concluded.

CPX-351 (Vyxeos) has been approved by the Food and Drug Administration and the European Medicines Agency for the treatment of adults with newly diagnosed therapy-related AML or AML with myelodysplastic syndrome–related changes.

The study was funded by Jazz Pharmaceuticals. Dr. Lancet disclosed that he has a consulting or advisory role for Agios, Daiichi Sankyo, Jazz Pharmaceuticals, and Pfizer.

CPX-351 (Vyxeos) has been approved by the Food and Drug Administration and the European Medicines Agency for the treatment of adults with newly diagnosed therapy-related AML or AML with myelodysplastic syndrome–related changes.

The study was funded by Jazz Pharmaceuticals. Dr. Lancet disclosed that he has a consulting or advisory role for Agios, Daiichi Sankyo, Jazz Pharmaceuticals, and Pfizer.

The use of CPX-351, a dual-drug liposomal encapsulation of cytarabine and daunorubicin, was tied to long-term remission and survival in older patients with newly diagnosed high-risk or secondary acute myeloid leukemia (AML), according to final results of a phase 3 study.

As part of the American Society of Clinical Oncology virtual scientific program, Jeffrey E. Lancet, MD, of the Moffitt Cancer Center in Tampa, Fla., presented the 5-year final data from a trial comparing CPX-351 vs. the conventional 7+3 regimen of cytarabine and daunorubicin in more than 300 older adult patients (age 60-75 years) with newly diagnosed high-risk or secondary AML. Early mortality rates for CPX-351 vs. 7+3 were 6% vs. 11% at Day 30 and 14% vs. 21% at day 60, respectively.

The final 5-year follow-up results had a median follow-up of just greater than 60 months, and maintained the improved median overall survival previously observed in the trial with CPX-351 (153 patients), compared with 7+3 (155 patients), Dr. Lancet reported.

Allogeneic hematopoietic stem cell transplant was received by 35% of the patients in the CPX-351 arm and 25% of patients in the 7+3 arm. The median overall survival after transplant was not reached for the CPX-351 arm, compared with 10.3 months with the 7+3 treated patients.

Remission, either complete remission or complete remission with incomplete neutrophil or platelet recovery, was achieved by 48% of patients in the CPX-351 arm and 33% of patients in the 7+3 arm, according to the results of the 5-year follow-up. In addition, among all patients who achieved remission, median overall survival was longer with CPX-351 than with 7+3, and the Kaplan-Meier estimated survival rate was higher for CPX-351 at both 3 years and 5 years.

At 5 years of follow-up, 81% of patients in the CPX-351 arm and 93% of patients in the 7+3 arm had died, with similar causes cited in each arm. Progressive leukemia was the most common primary cause of death in both treatment arms, according to Dr. Lancet.

At about 18 months’ follow-up in treatment naive acute myelogenous leukemia (AML) patients who were 75 years or older or otherwise unfit for intensive chemotherapy, median overall survival (OS) was 8.4 months when they were randomized to low-dose cytarabine (LDAC) plus the BCL-2 inhibitor venetoclax versus 4.1 months with LDAC plus placebo. The results from the phase 3 trial were reported at the virtual annual congress of the European Hematology Association.

The combination also improved rates of remission, event-free survival, and patient reported outcomes and lessened transfusion requirements. Adverse events were manageable.

The findings position venetoclax add-on with LDAC “as a potential new standard of care” for untreated patients ineligible for intensive chemotherapy, lead investigator Andrew Wei, MD, PhD, an AML researcher at Monash University, Melbourne, said at the meeting.

The study addresses a substantial unmet need. The median age at AML diagnosis is over 68 years old and comorbidities such as heart failure and reduced creatinine clearance are common, which make the risk of toxicity with standard chemotherapy too high. Single-agent alternatives are of limited benefit, so Dr. Wei’s group and others are looking for better options to plug the treatment gap when standard chemotherapy is contraindicated.

Several combinations are under investigation, including LDAC plus venetoclax, which appears to have a synergistic effect greater than either agent on its own, Dr. Wei and colleagues explained in their journal report, which was published online to coincide with his presentation (Blood. 2020 Jun 11;135(24):2137-45).

“A challenging AML population”

In the study, 143 patients were randomized to oral venetoclax 600 mg daily and 68 to placebo in 28-day cycles, on a background of LDAC 20 mg/m² administered subcutaneously on days 1-10 of each cycle.

“This study enrolled a challenging AML population, with nearly 60% age ≥75 years and a high proportion of patients with secondary disease (38%), prior hypomethylating agent (HMA) treatment (20%), poor cytogenetic risk (32%), and TP53 mutations (15%), which are known factors associated with dismal prognosis in AML,” the investigators noted in their report.

There was a numerical benefit in OS at 12 months – the preplanned primary outcome – but it was not statistically significant. At 18 months, however, and after adjustment for a higher rate of secondary AML in the venetoclax arm and other confounders in a post hoc analysis, survival differences reached significance. The 4.3-month OS benefit with the combination translated into a 30% reduction in the risk of death (hazard ratio, 0.70; 95% confidence interval, 0.50-0.99; P = .04)

Survival outcomes “were particularly promising for patient subgroups with NPM1- (median OS, not reached) and IDH1/2-mutant AML (median OS, 19.4 months),” the team noted.

Complete remission (CR) were 48% in the venetoclax arm, compared with 13% in the placebo group, and 34% of venetoclax patients versus 3% of placebo patients went into remission after their first cycle. Venetoclax subjects also had longer median event free survival (4.7 months vs. 2 months); higher rates of red blood cell and platelet transfusion independence (37% vs. 16%); and higher rates of cytometric minimal residual disease levels below 0.1% (6% vs. 1%).

The findings correlated with “strong improvements” in patient-reported outcomes, including fatigue and quality of life, the investigators reported.
 

Risk mitigation

Grade 3 or higher adverse events (AEs) included febrile neutropenia (32% in the venetoclax arm versus 29% in the placebo group), neutropenia (47% venetoclax vs. 16% placebo), thrombocytopenia (45% vs. 37%), and anemia (25% vs. 22%). The eight cases of tumor lysis syndrome (TLS) were all in the venetoclax arm. Grade 3 or higher bleeding was higher in the venetoclax arm (11% versus 7%), but the incidence of fatal bleeding was similar between the groups (1.4% venetoclax versus 1.5%).

“Although the venetoclax arm showed modest increases in hematologic AEs, the rate of AEs leading to treatment discontinuation (24% vs. 25%) and the rate of serious AEs such as pneumonia” and sepsis “were nearly identical between” the arms, the team said.

The combination “is more myelosuppressive,” but the effects “were mostly mitigated by venetoclax dose interruptions and reductions.” To mitigate the TLS risk, patients were hospitalized for TLS evaluation and prophylaxis during the 4-day venetoclax ramp-up in the first treatment cycle and for 24 hours after the 600-mg target was reached. “I think this is an extremely important measure to avoid this small but important complication,” Dr. Wei said at the meeting.
 

A moderate step forward

Dr. Lowenberg and Dr. Huls noted in their commentary that, despite the favorable outcomes, “the results are still sobering with a rapid drop of the survival curves to values of [around] 25% or less within 18 months, and event-free survival rates even falling to considerably lower levels.”

Also, there was a “weak correlation between the relatively wide differences in comparative CR/CRi rates and the much smaller differences in survival,” perhaps “due to a limited depth of the complete responses following venetoclax-LDAC therapy or the early development of therapeutic resistance,” they said.

The commentary also noted another option, adding the hedgehog pathway inhibitor glasdegib, instead of venetoclax, to LDAC. It also improved survival in a similar randomized study in unfit AML and high-risk myelodysplastic syndrome patients, from a median survival of 4.9 months with LDAC alone to 8.8 months with the combination (Leukemia. 2019 Feb;33(2):379-389. doi: 10.1038/s41375-018-0312-9).
 

Dueling regimens

Another alternative approach – venetoclax plus the HMA agent azacitidine – garnered a lot of attention at the meeting when it was reported that the combination had a median overall survival of 14.7 months, versus 9.6 months with azacitidine alone, in patients ineligible for intensive chemotherapy. CR/CRi rates were 66% with the combination, versus 28%.

“It seems like the results were better with the combination of venetoclax and azacitidine” than venetoclax plus LDAC, said Gunnar Juliusson, MD, PhD, of Lund (Sweden) University, who moderated Dr. Wei’s presentation.

He wanted to know if there was a way to identify patients who would do better on one regimen versus the other and was curious about the fact that the azacitidine study used a dose of 400 mg venetoclax, instead of 600 mg.

Dr. Wei noted the high incidence of poor prognostic factors in his study, including prior HMA treatment in 20%, but also that “we don’t know for sure” if there’s a clinically meaningful benefit with the higher dose.

He also said the optimal number of venetoclax cycles for best response is unknown. For now, treatment is “recommend until either [disease] progression, dose intolerance, or patient or physician preference,” he noted. Venetoclax subjects in his study had a median of four treatment cycles versus two in the placebo group. Combination patients in the azacitidine study had a median of seven cycles versus 4.5 with placebo.

Venetoclax already carries an indication in the United States in combination with azacitidine, decitabine, or LDAC for newly-diagnosed AML in adults 75 years or older or who have comorbidities that preclude use of intensive induction chemotherapy, at a daily dosage of 400 mg with HMAs and 600 mg with LDAC.

Labeling notes that “continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.”

Both venetoclax trials were sponsored by the drug’s maker, AbbVie, which was involved with data interpretation and other matters. Dr. Wei is a consultant for and receives research funding from the company and also receives royalty payments in relation to venetoclax. The commentators did not have any competing financial interests. Disclosures, if any, were not reported for Dr. Juliusson.

The COVID-19 pandemic in New York City led to a surge in out-of-hospital cardiac arrests (OHCAs) that placed a huge burden on first responders, a new analysis shows.

During the height of the pandemic in New York, there was a “dramatic increase in cardiopulmonary arrests, nearly all presented in non-shockable cardiac rhythms (> 90% fatality rate) and vulnerable patient populations were most affected,” David J. Prezant, MD, chief medical officer, Fire Department of New York (FDNY), said in an interview.

In a news release, Dr. Prezant noted that “relatively few, if any, patients were tested to confirm the presence of COVID-19,” making it impossible to distinguish between cardiac arrests as a result of COVID-19 and those that may have resulted from other health conditions.

“We also can’t rule out the possibility that some people may have died from delays in seeking or receiving treatment for non–COVID-19-related conditions. However, the dramatic increase in cardiac arrests compared to the same period in 2019 strongly indicates that the pandemic was directly or indirectly responsible for that surge in cardiac arrests and deaths,” said Dr. Prezant.

The study was published online June 19 in JAMA Cardiology.

New York City has the largest and busiest EMS system in the United States, serving a population of more than 8.4 million people and responding to more than 1.5 million calls every year.

To gauge the impact of COVID-19 on first responders, Dr. Prezant and colleagues analyzed data for adults with OHCA who received EMS resuscitation from March 1, when the first case of COVID-19 was diagnosed in the city, through April 25, when EMS call volume had receded to pre-COVID-19 levels.

Compared with the same period in 2019, the COVID-19 period had an excess of 2,653 patients with OHCA who underwent EMS resuscitation attempts (3,989 in 2020 vs. 1,336 in 2019, P < .001), an incidence rate triple that of 2019 (47.5 vs. 15.9 per 100,000).

On the worst day – Monday, April 6 – OHCAs peaked at 305 cases, an increase of nearly 10-fold compared with the same day in 2019.

Despite the surge in cases, the median response time of available EMS units to OHCAs increased by about 1 minute over 2019, a nonsignificant difference. Although the average time varied, median response time during the COVID-19 period was less than 3 minutes.

A more vulnerable group

Compared with 2019, patients suffering OHCA during the pandemic period were older (mean age 72 vs. 68 years), less likely to be white (20% white vs. 33%) and more likely to have hypertension (54% vs. 46%), diabetes (36% vs. 26%), physical limitations (57% vs. 48%) and cardiac rhythms that don’t respond to defibrillator shocks (92% vs. 81%).

Compared with 2019, the COVID-19 period had substantial reductions in return of spontaneous circulation (ROSC) (18% vs. 35%; P < .001) and sustained ROSC (11% vs. 25%; P < .001). The case fatality rate was 90% in the COVID-19 period vs. 75% a year earlier.

“The tragedy of the COVID-19 pandemic is not just the number of patients infected, but the large increase in OHCAs and deaths,” Dr. Prezant and colleagues said.

Identifying patients with the greatest risk for OHCA and death during the COVID-19 pandemic “should allow for early, targeted interventions in the outpatient setting that could lead to reductions in out-of-hospital deaths,” they noted.

“Vulnerable patient populations need outreach, telephonic medicine, televideo medicine, home visits, not just temperature monitoring but home O₂ saturation monitoring,” Dr. Prezant said in an interview. “Barriers need to be removed, not just for this pandemic but for the future – no matter what the trigger is.”
 

Unsung heroes

In an Editor’s Note in JAMA Cardiology, Robert O. Bonow, MD, Northwestern University, Chicago, and colleagues said the American people owe a debt of gratitude to first responders for their “heroic work” triaging, resuscitating, and transporting thousands of people affected by COVID-19. 

“Although the typically bustling NYC streets remained eerily deserted, the characteristic cacophony of sounds of the ‘City that Never Sleeps’ was replaced by sirens wailing all hours of the night,” they wrote.

First responders to OHCAs in the COVID-19 era place themselves at extremely high risk, in some cases without optimal personal protective equipment, they pointed out. “Sadly,” many first responders have fallen ill to COVID-19 infection, they added.

As of June 1, 29 EMS workers and volunteers across the United States had died of COVID-19.

They are James Villecco, Gregory Hodge, Tony Thomas, Mike Field, John Redd, Idris Bey, Richard Seaberry, and Sal Mancuso of New York; Israel Tolentino, Reuven Maroth, Liana Sá, Kevin Leiva, Frank Molinari, Robert Weber, Robert Tarrant, Solomon Donald, Scott Geiger, John Farrarella, John Careccia, Bill Nauta, and David Pinto of New Jersey; Kevin Bundy, Robert Zerman, and Jeremy Emerich of Pennsylvania; Paul Cary of Colorado; Paul Novicki of Michigan; David Martin of Mississippi; Billy Birmingham of Missouri; and John “JP” Granger of South Carolina.

“We offer their families, friends, and colleagues our sincerest condolences and honor their memory with our highest respect and gratitude,” Dr. Bonow and colleagues wrote.

The COVID-19 pandemic in New York City led to a surge in out-of-hospital cardiac arrests (OHCAs) that placed a huge burden on first responders, a new analysis shows.

During the height of the pandemic in New York, there was a “dramatic increase in cardiopulmonary arrests, nearly all presented in non-shockable cardiac rhythms (> 90% fatality rate) and vulnerable patient populations were most affected,” David J. Prezant, MD, chief medical officer, Fire Department of New York (FDNY), said in an interview.

In a news release, Dr. Prezant noted that “relatively few, if any, patients were tested to confirm the presence of COVID-19,” making it impossible to distinguish between cardiac arrests as a result of COVID-19 and those that may have resulted from other health conditions.

“We also can’t rule out the possibility that some people may have died from delays in seeking or receiving treatment for non–COVID-19-related conditions. However, the dramatic increase in cardiac arrests compared to the same period in 2019 strongly indicates that the pandemic was directly or indirectly responsible for that surge in cardiac arrests and deaths,” said Dr. Prezant.

The study was published online June 19 in JAMA Cardiology.

New York City has the largest and busiest EMS system in the United States, serving a population of more than 8.4 million people and responding to more than 1.5 million calls every year.

To gauge the impact of COVID-19 on first responders, Dr. Prezant and colleagues analyzed data for adults with OHCA who received EMS resuscitation from March 1, when the first case of COVID-19 was diagnosed in the city, through April 25, when EMS call volume had receded to pre-COVID-19 levels.

Compared with the same period in 2019, the COVID-19 period had an excess of 2,653 patients with OHCA who underwent EMS resuscitation attempts (3,989 in 2020 vs. 1,336 in 2019, P < .001), an incidence rate triple that of 2019 (47.5 vs. 15.9 per 100,000).

On the worst day – Monday, April 6 – OHCAs peaked at 305 cases, an increase of nearly 10-fold compared with the same day in 2019.

Despite the surge in cases, the median response time of available EMS units to OHCAs increased by about 1 minute over 2019, a nonsignificant difference. Although the average time varied, median response time during the COVID-19 period was less than 3 minutes.

A more vulnerable group

Compared with 2019, patients suffering OHCA during the pandemic period were older (mean age 72 vs. 68 years), less likely to be white (20% white vs. 33%) and more likely to have hypertension (54% vs. 46%), diabetes (36% vs. 26%), physical limitations (57% vs. 48%) and cardiac rhythms that don’t respond to defibrillator shocks (92% vs. 81%).

Compared with 2019, the COVID-19 period had substantial reductions in return of spontaneous circulation (ROSC) (18% vs. 35%; P < .001) and sustained ROSC (11% vs. 25%; P < .001). The case fatality rate was 90% in the COVID-19 period vs. 75% a year earlier.

“The tragedy of the COVID-19 pandemic is not just the number of patients infected, but the large increase in OHCAs and deaths,” Dr. Prezant and colleagues said.

Identifying patients with the greatest risk for OHCA and death during the COVID-19 pandemic “should allow for early, targeted interventions in the outpatient setting that could lead to reductions in out-of-hospital deaths,” they noted.

“Vulnerable patient populations need outreach, telephonic medicine, televideo medicine, home visits, not just temperature monitoring but home O₂ saturation monitoring,” Dr. Prezant said in an interview. “Barriers need to be removed, not just for this pandemic but for the future – no matter what the trigger is.”

Azacitidine plus enasidenib improved complete and overall responses in newly diagnosed acute myelogenous leukemia with isocitrate dehydrogenase 2 gene mutations, compared with azacitidine alone, but it did not improve overall survival in an open-label, phase 2 trial reported at the virtual annual congress of the European Hematology Association.

“Given the very high cost of” enasidenib, and the lack of survival benefit, Gunnar Juliusson, MD, PhD, of Lund University, Sweden, who moderated the study presentation, wondered if it might make more sense to hold enasidenib in reserve until after progression on azacitidine.

“The challenge is going to be exactly” that, “trying to figure out [if] you use both things together” or in sequence. “You can look at it in both ways,” said lead investigator Courtney DiNardo, MD, associate professor in the department of leukemia at the University of Texas MD Anderson Cancer Center, Houston.

“We do know” that with enasidenib monotherapy, there’s “a decrement in the rates of remission and in the duration of response” and overall survival in the salvage setting, so there’s “a clear rationale to give it earlier rather than later,” but “I think this study in some ways provides a few more questions than it really answers,” she said at the meeting.

About 15% of AML patients have leukemogenic isocitrate dehydrogenase 2 (IDH2) mutations; enasidenib, an oral small molecule, inhibits the mutant enzyme. The older AML patients are, the more likely they are to have an IDH2 mutation, so the work “is relevant to our older chemotherapy ineligible population,” Dr. DiNardo said.

The trial was prompted by preclinical indications of synergy with azacitidine; alone, each agent has an overall response rate of about 30% in newly diagnosed AML, and a complete remission (CR) rate of about 20%, she explained.

Her team randomized 68 adults with newly diagnosed AML and an IDH2 mutation to enasidenib 100 mg daily on a 28-day cycle with subcutaneous azacitidine 75 mg/m² for 7 days during the cycle, and 33 others to just the azacitidine alone.

Their subjects were ineligible for intensive chemotherapy and had intermediate to poor risk cytogenetics. The median age was 75 years, and Eastern Cooperative Oncology Group performance scores were 2 or less.

The overall response rate was 71% with the combination and 42% in the azacitidine alone arm (P = .0064). Fifty-three percent of combination patients, but 12% of azacitidine alone subjects, had complete remissions (P = .0001). The median duration of response with combination therapy was 24.1 months, versus 12.1 months.

Enasidenib plus azacitidine subjects also had greater drops in mutant IDH2 variant allele frequency (median 83.4% versus 17.7%, P < .01) and levels of the downstream oncometabolite 2-hydroxyglutarate (97.8% versus 54.3%; P < .01).

However, median OS was 22 months in both arms (HR 0.99, 95% CI 0.52, 1.87, P = .97). Although median event-free survival favored the combination – 17.2 months versus 10.8 – the results were not statistically significant (HR 0.59, 95% CI 0.30, 1.17, P = .13).

A possible reason for the lack of survival benefit, Dr. DiNardo said, was that seven azacitidine-alone patients (21%) went on to enasidenib after leaving the study, most commonly for disease progression, which occurred in 31% of combination patients versus 52% in the azacitidine-alone arm.

Combination subjects had a median of 10 treatment cycles, vs. 7 in the azacitidine-alone group. Grade 3-4 adverse events included thrombocytopenia (37% combination, 19% azacitidine-alone), neutropenia (35% vs. 22%), anemia (19% vs. 22%), and febrile neutropenia (15% vs. 16%). Grade 3-4 infections were more common with azacitidine monotherapy (31% vs. 18%).

Twelve enasidenib/azacitidine subjects (18%) developed isocitrate dehydrogenase differentiation syndrome, a complication that carries a black box warning in enasidenib’s label.

The work was funded by enasidenib marketer Celgene. Dr. DiNardo is an adviser to, and receives research funding from, the company. Dr. Juliusson’s disclosures, if any, were not reported.

The first official U.S. case of Guillain-Barré syndrome (GBS) associated with COVID-19 has been reported by neurologists from Allegheny General Hospital in Pittsburgh, further supporting a link between the virus and neurologic complications, including GBS.

Physicians in China reported the first case of COVID-19 that initially presented as acute GBS. The patient was a 61-year-old woman returning home from Wuhan during the pandemic.

Subsequently, physicians in Italy reported five cases of GBS in association with COVID-19.

The first U.S. case is described in the June issue of the Journal of Clinical Neuromuscular Disease.

Like cases from China and Italy, the U.S. patient’s symptoms of GBS reportedly occurred within days of being infected with SARS-CoV-2. “This onset is similar to a case report of acute Zika virus infection with concurrent GBS suggesting a parainfectious complication,” first author Sandeep Rana, MD, and colleagues noted.

The 54-year-old man was transferred to Allegheny General Hospital after developing ascending limb weakness and numbness that followed symptoms of a respiratory infection. Two weeks earlier, he initially developed rhinorrhea, odynophagia, fevers, chills, and night sweats. The man reported that his wife had tested positive for COVID-19 and that his symptoms started soon after her illness. The man also tested positive for COVID-19.

His deficits were characterized by quadriparesis and areflexia, burning dysesthesias, mild ophthalmoparesis, and dysautonomia. He did not have the loss of smell and taste documented in other COVID-19 patients. He briefly required mechanical ventilation and was successfully weaned after receiving a course of intravenous immunoglobulin.

Compared with other cases reported in the literature, the unique clinical features in the U.S. case are urinary retention secondary to dysautonomia and ocular symptoms of diplopia. These highlight the variability in the clinical presentation of GBS associated with COVID-19, the researchers noted.

They added that, with the Pittsburgh patient, electrophysiological findings were typical of demyelinating polyneuropathy seen in patients with GBS. The case series from Italy suggests that axonal variants could be as common in COVID-19–associated GBS.

“Although the number of documented cases internationally is notably small to date, it’s not completely surprising that a COVID-19 diagnosis may lead to a patient developing GBS. The increase of inflammation and inflammatory cells caused by the infection may trigger an irregular immune response that leads to the hallmark symptoms of this neurological disorder,” Dr. Rana said in a news release.

“Since GBS can significantly affect the respiratory system and other vital organs being pushed into overdrive during a COVID-19 immune response, it will be critically important to further investigate and understand this potential connection,” he added.

The 54-year-old man was transferred to Allegheny General Hospital after developing ascending limb weakness and numbness that followed symptoms of a respiratory infection. Two weeks earlier, he initially developed rhinorrhea, odynophagia, fevers, chills, and night sweats. The man reported that his wife had tested positive for COVID-19 and that his symptoms started soon after her illness. The man also tested positive for COVID-19.

His deficits were characterized by quadriparesis and areflexia, burning dysesthesias, mild ophthalmoparesis, and dysautonomia. He did not have the loss of smell and taste documented in other COVID-19 patients. He briefly required mechanical ventilation and was successfully weaned after receiving a course of intravenous immunoglobulin.

Compared with other cases reported in the literature, the unique clinical features in the U.S. case are urinary retention secondary to dysautonomia and ocular symptoms of diplopia. These highlight the variability in the clinical presentation of GBS associated with COVID-19, the researchers noted.

They added that, with the Pittsburgh patient, electrophysiological findings were typical of demyelinating polyneuropathy seen in patients with GBS. The case series from Italy suggests that axonal variants could be as common in COVID-19–associated GBS.

“Although the number of documented cases internationally is notably small to date, it’s not completely surprising that a COVID-19 diagnosis may lead to a patient developing GBS. The increase of inflammation and inflammatory cells caused by the infection may trigger an irregular immune response that leads to the hallmark symptoms of this neurological disorder,” Dr. Rana said in a news release.

“Since GBS can significantly affect the respiratory system and other vital organs being pushed into overdrive during a COVID-19 immune response, it will be critically important to further investigate and understand this potential connection,” he added.

Atopic eczema was linked with a significantly increased risk of lymphoma, and severe eczema was associated with a twofold increase in non-Hodgkin lymphoma (NHL) risk, according to two matched longitudinal cohort studies from England and Denmark.

“In this study, no evidence was found that people with atopic eczema are at increased risk of most cancers. An exception is the observed association between atopic eczema and lymphoma, particularly NHL, [which] increased with eczema severity,” Kathryn E. Mansfield, PhD, wrote in JAMA Dermatology. Adjusted hazard ratios for NHL in the English cohort were 1.06 (99% CI, 0.90-1.25) for mild atopic eczema, 1.24 (99% CI, 1.04-1.48) for moderate eczema, and 2.08 (99% CI, 1.42-3.04) for severe eczema, reported Dr. Mansfield of the London School of Hygiene and Tropical Medicine and associates.

Past studies of a possible link between atopic eczema and cancer have produced conflicting evidence, which might reflect “two competing theories” – that cancer risk falls with greater immune surveillance, and that cancer risk rises with immune stimulation, the researchers wrote. Immunosuppressive treatment and an impaired skin barrier might also increase the risk of cancer, but the evidence is conflicting.

For the study, they analyzed electronic health records linked with hospital admissions and death records in England and national health registry data from Denmark. The English cohort included 471,970 adults with atopic eczema and 2,239,775 adults without atopic eczema. The Danish cohort was composed of individuals of any age, including 44,945 who had eczema and with 445,673 who did not. Participants were matched based on factors such as age, sex, and primary care practice. The researchers excluded individuals with a history of cancer, apart from nonmelanoma skin cancer or keratinocyte cancer. (For analyses of skin cancer risk, they also excluded individuals with a history of nonmelanoma skin cancer.)

Overall, there was “little evidence” for a link between atopic eczema and cancer (adjusted hazard ratio in England, 1.04; 99% CI, 1.02-1.06; aHR in Denmark, 1.05; 99% CI, 0.95-1.16) or for most specific types of cancer, the investigators wrote.

In England, however, eczema was associated with a significantly increased risk for noncutaneous lymphoma, with an adjusted HRs of 1.19 (99% CI, 1.07-1.34) for NHL, and 1.48 (99% CI, 1.07-2.04) for Hodgkin lymphoma. Lymphoma risk was highest among adults with severe eczema, defined as those who had been prescribed a systemic treatment for their disease, who had received phototherapy, or who had been referred to a specialist or admitted to a hospital for atopic eczema. Point estimates in the Danish cohort also revealed a higher risk for lymphoma among individuals with moderate to severe atopic eczema, compared with those with eczema, but the 99% CIs crossed 1.0.

The findings highlight the need to be aware of, screen for, and study the pathogenesis of heightened lymphoma risk among patients with atopic eczema, said Shawn Demehri, MD, PhD, of the department of dermatology and cancer center, at Massachusetts General Hospital, Boston, who was not involved in the study.

“Prospectively collected data from large cohorts of eczema patients is a strength of this study,” he said in an interview. “However, the age range included in the study is suboptimal for assessing cancer as an outcome. The lower incidence of cancer in younger individuals hinders the ability to detect differences in cancer risk between the two groups.” (Approximately 57% of individuals in the English cohort were aged 18-44 years, while approximately 70% of those in the Danish cohort were less than 18 years.)

Understanding how eczema affects the risk of non-Hodgkin lymphoma is an important future direction of research, Dr. Demehri emphasized. “The landscape of atopic eczema therapeutics has dramatically changed in the recent years. It will be very interesting to determine how new biologics impact cancer risk in eczema patients.”

Partial support for the work was provided by the Wellcome Trust, the Royal Society, the Dagmar Marshalls Fund, and the Aase and Ejnar Danielsens Fund. Dr. Mansfield disclosed support from a Wellcome Trust grant. Her coinvestigators disclosed ties to TARGET-DERM, Pfizer, and GlaxoSmithKline, and from the Wellcome Trust, Medical Research Council, the National Institute for Health Research, the British Heart Foundation, Diabetes UK, and IMI Horizon 2020 funding BIOMAP. Dr. Demehri reported having no relevant conflicts of interest.

Therapy-related acute lymphoblastic leukemia (tALL) is less common and less well known than therapy-related acute myeloid leukemia, but tALL also appears to be associated with poor-prognosis features, compared with de novo ALL, investigators said.

“Currently, this condition is not fully recognized by the [World Health Organization] classification, but it has emerged as a relevant and increasingly common form of ALL. There is no standardized therapy for tALL at this time due to the rarity of the condition. Therefore, more information regarding characteristics, prognosis, and treatment is needed,” wrote Brayan Merchán, MD, and colleagues at Princess Margaret Hospital in Toronto.

At their center, the median overall survival (OS) among 58 patients with tALL who received front line induction therapy was 13 months, although patients who were able to undergo hematopoietic stem cell transplant had a 400% longer OS than patients who did not receive HSCT, they reported in an electronic poster presented as part of the virtual annual congress of the European Hematology Association.

A hematologist-oncologist who has studied tALL agreed that it appears to be a distinct clinical entity from de novo ALL.

“It is distinct from the other ALL because the age [at diagnosis] is different, the cytogenetic and molecular profiles are different, and while responses are the same, it seems that survival is lower in cases who don’t go through bone marrow transplant as consolidation,” said Ibrahim Aldoss, MD, from City of Hope Medical Center in Duarte, Calif.

Dr. Aldoss, who was not involved in the study, was the lead author of a study published in 2018 which found that, “[a]lthough survival of therapy-related acute lymphoblastic leukemia was inferior to de novo cases, allogeneic hematopoietic cell transplantation outcomes were comparable for the two entities” (Haematologica. 2018 Oct; 103[10]:1662-8).

He noted that induction regimen options for patients with tALL may be limited because some patients may had previous exposures to cytotoxic chemotherapy agents – such as anthracyclines used in standard regimens for breast cancer – that have cumulative toxicities and lifetime dose limits.

In addition, “these patients tend to be older, because they went through another cancer and then developed therapy-related ALL, and usually they’re not eligible for pediatric-inspired regimens that we use more frequently in younger patients,” he said.
 

Retrospective study

Dr. Merchán and colleagues conducted a retrospective study of all consecutive adults with ALL treated at their center from 1999 to 2019 and followed until January 2020. Of this group, they identified 59 patients who had been exposed to chemotherapy or radiation for other diseases prior to their ALL diagnosis.

The mean age of the 59 patients (31 women and 28 men) was 54.7 years. In all, 34 had solid cancers and 25 had hematologic malignancies before their ALL diagnosis. The most common diagnosis was breast cancer in 15 patients, followed by multiple myeloma in 11, lymphoma in 7, and AML in 5. Other prior diagnoses were not specified.

Prior therapies included chemotherapy alone in 18 patients, radiotherapy alone in 19, and 20 had both treatment modalities (information about 2 remaining patients was not presented).

For the overall population the median time to tALL diagnosis was 5 years, but for 9 patients with the poor-prognosis MLL gene rearrangement the median time to tALL was just 21 months. The disease latency period was 21 months for patients who received chemotherapy, compared with 117 months for patients treated with radiotherapy.

The majority of patients (53) had B-phenotype ALL. Of the 49 for whom cytogenetic data were available, 41 had cytogenetic abnormalities, including the MLL rearrangement in 9, and complex karyotype in 7. Of all 59 patients, 12 had translocation t(9;22).

One patient did not undergo induction therapy for ALL because of poor performance status. All of the other patients received induction therapy, either a Dana-Farber Cancer Institute protocol in 44 patients, hyper-CVAD (cyclophosphamide, vincristine, doxorubicin, and dexamethasone) in 5, or blinatumomab in 3.

A complete response was seen in 41 patients (70%); 7 patients died during induction from causes attributed to therapy.

The mean follow-up for all patients was 27 months, and median overall survival was 13 months.

Median overall survival was 98 months for patients who underwent allogeneic HSCT versus a median of 19 months for patients who did not undergo transplant. This difference was not statistically significant, however, likely because of the small sample size.

Causes of death in 11 patients after transplant included relapse in 4 and graft-versus-host disease in 2 (other causes were not specified). Among the 34 patients who did not undergo HSCT following induction, 15 died from disease progression.

“From our results, tALL patients who were able to receive HSCT had better OS. Our data also supports the notion that tALL may be distinct entity with poor prognosis features compared to de novo ALL,” the investigators concluded.

The authors did not disclose a funding source. Dr. Merchán and Dr. Aldoss reported no relevant disclosures.

Across the globe, there are marked differences in how countries responded to the COVID-19 outbreak, with varying degrees of success in limiting the spread of the virus. Some countries learned important lessons from previous outbreaks, including SARS and MERS, and put policies in place that contributed to lower infection and death rates from COVID-19 in these countries. Others struggled to respond appropriately to the outbreak.

The United States and most of the world was not affected significantly by SARS and MERS. Hence there is a need for different perspectives and observations on lessons that can be learned from this outbreak to help develop effective strategies and policies for the future. It also makes sense to focus intently on the demographic most affected by COVID-19 – the elderly.

Medical care, for the most part, is governed by protocols that clearly detail processes to be followed for the prevention and treatment of disease. Caring for older patients requires going above and beyond the protocols. That is one of the lessons learned from the COVID-19 pandemic – a wake-up call for a more proactive approach for at-risk patients, in this case everyone over the age of 60 years.

In this context, it is important for medical outreach to continue with the senior population long after the pandemic has run its course. Many seniors, particularly those susceptible to other illnesses or exhibiting ongoing issues, would benefit from a consistent and preplanned pattern of contacts by medical professionals and agencies that work with the aging population. These proactive follow-ups can facilitate prevention and treatment and, at the same time, reduce costs that would otherwise increase when health care is reactive.
 

Lessons in infectious disease containment

As COVID-19 spread globally, there were contrasting responses from individual countries in their efforts to contain the disease. Unfortunately, Italy suffered from its decision to lock down only specific regions of the country initially. The leadership in Italy may have ignored the advice of medical experts and been caught off guard by the intensity of the spread of COVID-19. In fact, they might not have taken strict actions right away because they did not want their responses to be viewed as an overreaction to the disease.

The government decided to shut down areas where the infection rates were high (“red zones”) rather than implement restrictions nationally. This may have inadvertently increased the spread as Italians vacated those “red zones” for other areas of the country not yet affected by COVID-19. Italy’s decentralized health care system also played a part in the effects of the disease, with some regions demonstrating more success in slowing the reach of the disease. According to an article in the Harvard Business Review, the neighboring regions of Lombardy and Veneto applied similar approaches to social distancing and retail closures. Veneto was more proactive, and its response to the outbreak was multipronged, including putting a “strong emphasis on home diagnosis and care” and “specific efforts to monitor and protect health care and other essential workers.” These measures most likely contributed to a slowdown of the spread of the disease in Veneto’s health care facilities, which lessened the load on medical providers.¹

Conversely, Taiwan implemented proactive measures swiftly after learning about COVID-19. Taiwan was impacted adversely by the SARS outbreak in 2003 and, afterward, revised their medical policies and procedures to respond quickly to future infectious disease crises. In the beginning, little was known about COVID-19 or how it spread. However, Taiwan’s swift public health response to COVID-19 included early travel restrictions, patient screening, and quarantining of symptomatic patients. The government emphasized education and created real-time digital updates and alerts sent to their citizens, as well as partnering with media to broadcast crucial proactive health information and quickly disproving false information related to COVID-19. They coordinated with organizations throughout the country to increase supplies of personal protective equipment (PPE).²

Although countries and even cities within a country differ in terms of population demographics, health resources, government policies, and cultural practices, initial success stories have some similarities, including the following:

• Early travel restrictions from countries with positive cases, with some circumstances requiring compulsory quarantine periods and testing before entry.
• Extensive testing and proactive tracing of symptomatic cases early. Contacts of people testing positive were also tested, irrespective of being symptomatic or asymptomatic. If testing kits were unavailable, the contacts were self-quarantined.
• Emphasis on avoiding overburdening hospitals by having the public health infrastructure to divert people exhibiting symptoms, including using public health hotlines to send patients to dedicated testing sites and drive-through testing, rather than have patients presenting to emergency rooms and hospitals. This approach protected medical staff from exposure and allowed the focus to remain on treating severe symptomatic patients.

The vastly different response to the COVID-19 outbreak in these two countries illuminates the need for better preparation in the United States. At the onset of this outbreak, emergency room medical professionals, hospitalists, and outpatient primary care providers did not know how to screen for or treat this virus. Additionally, there was limited information on the most effective contact protocols for medical professionals, patients, and visitors. Finally, the lack of PPE and COVID-19 test kits hindered the U.S. response. Once the country is on the road to recovery from COVID-19, it is imperative to set the groundwork to prepare for future outbreaks and create mechanisms to quickly identify vulnerable populations when outbreaks occur.
 

Senior care in future infectious disease outbreaks

How can medical providers translate lessons learned from this outbreak into improving the quality of care for seniors? The National Institute on Aging (NIA) maintains a website with information about healthy aging. Seniors and their caregivers can use this website to learn more about chronic diseases, lifestyle modifications, disease prevention, and mental health.

In times of a pandemic, this website provides consistent and accurate information and education. One recommendation for reaching the elderly population during future outbreaks is for NIA to develop and implement strategies to increase the use of the website, including adding more audio and visual interfaces and developing a mobile app. Other recommendations for improving the quality of care for seniors include the following:

1. Identify which populations may be most affected when future outbreaks occur.

2. Consider nontraditional platforms, including social media, for communicating with the general population and for medical providers worldwide to learn from each other about new diseases, including the signs, symptoms, and treatment plans. Some medical professionals created specific WhatsApp groups to communicate, and the World Health Organization sent updated information about COVID-19 to anyone who texted them via WhatsApp.³

3. Create a checklist of signs and symptoms related to current infectious diseases and assess every vulnerable patient.

4. Share these guidelines with medical facilities that treat these populations, such as senior care, assisted living and rehabilitation facilities, hospitals, and outpatient treatment centers. Teach the staff at these medical facilities how to screen patients for signs and symptoms of the disease.

5. Implement social isolation strategies, travel and visitor restrictions, and testing and screening as soon as possible at these medical facilities.

6. Recognize that these strategies may affect the psychological and emotional well-being of seniors, increasing their risk for depression and anxiety and negatively affecting their immunity and mental health. Additionally, the use of PPE, either by the medical providers or the patient, may cause anxiety in seniors and those with mild cognitive impairment.

7. Encourage these medical facilities to improve coping strategies with older patients, such as incorporating communication technology that helps seniors stay connected with their families, and participating in physical and mental exercise, as well as religious activities.

8. Ask these medical facilities to create isolation or quarantine rooms for infected seniors.

9. Work with family members to proactively report to medical professionals any symptoms noticed in their senior relatives. Educate seniors to report symptoms earlier.

10. Offer incentives for medical professionals to conduct on-site testing in primary care offices or senior care facilities instead of sending patients to hospital emergency rooms for evaluation. This will only be effective if there are enough test kits available.

11. Urge insurance companies and Medicare to allow additional medical visits for screening vulnerable populations. Encourage the use of telemedicine in place of in-office visits (preferably billed at the same rate as an in-office visit) where appropriate, especially with nonambulatory patients or those with transportation issues. Many insurance companies, including Medicare, approved COVID-19–related coverage of telemedicine in place of office visits to limit the spread of the disease.

12. Provide community health care and integration and better coordination of local, state, and national health care.

13. Hold regular epidemic and pandemic preparedness exercises in every hospital, nursing home, and assisted living facility.

Proactive health care outreach

It is easier to identify the signs and symptoms of already identified infectious diseases as opposed to a novel one like COVID-19. The United States faced a steep learning curve with COVID-19. Hospitalists and other medical professionals were not able to learn about COVID-19 in a journal. At first, they did not know how to screen patients coming into the ER, how to protect staff, or what the treatment plan was for this new disease. As a result, the medical system experienced disorder and confusion. Investing in community health care and better coordination of local, state, and national health care resources is a priority.

The senior citizen population appears to be most vulnerable to this virus and may be just as vulnerable in future outbreaks. Yet the insights gained from this pandemic can lead to a more comprehensive outreach to senior patients and increased screenings for comorbidities and future contagious diseases. An emphasis on proactive health care and outreach for seniors, with a focus on identifying and treating comorbid conditions, improves the medical care system overall and may prevent or slow future community outbreaks.

Across the globe, there are marked differences in how countries responded to the COVID-19 outbreak, with varying degrees of success in limiting the spread of the virus. Some countries learned important lessons from previous outbreaks, including SARS and MERS, and put policies in place that contributed to lower infection and death rates from COVID-19 in these countries. Others struggled to respond appropriately to the outbreak.

The United States and most of the world was not affected significantly by SARS and MERS. Hence there is a need for different perspectives and observations on lessons that can be learned from this outbreak to help develop effective strategies and policies for the future. It also makes sense to focus intently on the demographic most affected by COVID-19 – the elderly.

Medical care, for the most part, is governed by protocols that clearly detail processes to be followed for the prevention and treatment of disease. Caring for older patients requires going above and beyond the protocols. That is one of the lessons learned from the COVID-19 pandemic – a wake-up call for a more proactive approach for at-risk patients, in this case everyone over the age of 60 years.

In this context, it is important for medical outreach to continue with the senior population long after the pandemic has run its course. Many seniors, particularly those susceptible to other illnesses or exhibiting ongoing issues, would benefit from a consistent and preplanned pattern of contacts by medical professionals and agencies that work with the aging population. These proactive follow-ups can facilitate prevention and treatment and, at the same time, reduce costs that would otherwise increase when health care is reactive.
 

Lessons in infectious disease containment

As COVID-19 spread globally, there were contrasting responses from individual countries in their efforts to contain the disease. Unfortunately, Italy suffered from its decision to lock down only specific regions of the country initially. The leadership in Italy may have ignored the advice of medical experts and been caught off guard by the intensity of the spread of COVID-19. In fact, they might not have taken strict actions right away because they did not want their responses to be viewed as an overreaction to the disease.

The government decided to shut down areas where the infection rates were high (“red zones”) rather than implement restrictions nationally. This may have inadvertently increased the spread as Italians vacated those “red zones” for other areas of the country not yet affected by COVID-19.
