In the first part of the observer-blind, randomized, controlled study, 40 patients aged 5-6 years received either the new vaccine (BBio bOPV) or the licensed vaccine (SII bOPV). In the second part, 1,080 patients aged 6-8 weeks received either BBio bOPV or SII bOPV at age 6, 10, and 14 weeks. Blood samples were taken to assess neutralizing antibody responses against poliovirus types 1 and 3, and safety also was assessed.

In the first part of the study, 12 adverse events were reported, none of which were serious and none of which were related to the vaccines. All participants demonstrated seroprotective titers against both poliovirus types 1 month after vaccination.

In the second part, more than 96% of infants demonstrated seroprotection and seroconversion against both poliovirus types. Geometric mean titers were equivalent in both groups. A total of 387 participants had at least one adverse event, and 18 serious adverse events were reported. None of these were related to the vaccines.

“The BBio bOPV has been proven safe and immunogenic in the target infant population in Bangladesh. As the use of bOPV is expected to be continued until at least 2022, availability of new bOPV bulk manufacturer will be helpful in securing adequate supplies of bOPV for global demand in the polio endgame strategy,” the investigators concluded.

The study was funded by Bilthoven Biologicals. Four coauthors are employed by Bilthoven, manufacturer of the study vaccine; two others are employed by the Serum Institute of India, which provided the control vaccine.

Background: Acute cystitis is a common condition in women and associated with morbidity. A commonly recommended preventative measure is increased oral hydration, but there is limited evidence to support this claim.

Though antibiotic prophylaxis is more effective at reducing cystitis, increased daily water intake is a safe and inexpensive method to prevent cystitis without increasing exposure to antimicrobial therapy. This study did rely on information obtained from phone calls with patients. It is also an open-label study design in which patients were not blinded to their assigned group. This would be less of an issue if episodes of cystitis were confirmed with culture. Another limitation of this study is that it included only ambulatory patients and excluded patients with pyelonephritis, so it may be less applicable to our hospitalized patients.

Bottom line: This study shows a benefit in recurrent cystitis by increased water intake in premenopausal women.

The continuing outbreak of Ebola in the Democratic Republic of the Congo (DRC) was the subject of a special United Nations high-level event organized by the World Health Organization (WHO) and the United Nations Office for the Coordination of Humanitarian Affairs (OCHA). It was comoderated by Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization, and Mark Lowcock, the UN Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator.

The DRC Ebola outbreak has drawn continuing concern and was highlighted by an even greater feeling of urgency as a case of Ebola was reported to have spread to Goma, the largest city in the eastern part of the DRC and a major trading port “on the eve of the conference,” according to one speaker.

That same infected individual – a priest arriving by bus to the city from an affected area – died of the disease the day after the conference concluded, according to the DRC authorities.

In his opening remarks, Mr. Lowcock stressed the importance of coordinating international efforts with the on-the-ground responses being carried out under the direction of Oly Ilunga Kalenga, MD, the DRC’s Minister of Public Health, who was also present and spoke at the meeting. Dr. Kalenga resigned his post on July 22, 2019.*

Mr. Lowcock stressed three points in particular that make for unique changes to the current response, compared with the earlier outbreak of 2014-2016.

First, in the previous outbreak in West Africa, “we didn’t have the vaccine and we didn’t have some of the successful treatments” that are currently available. Furthermore, more than 160,000 people have now been vaccinated and “the vaccine has a high degree of effectiveness.” This is an asset compared to the previous situation, he stated.

In his second point, he warned that the outbreak in the DRC “is taking place in an insecure and complex area with multiple armed groups present and large-scale preexisting humanitarian needs. Special interests distort the context. A history of disaffection with national authorities and foreigners generates distrust and makes the response more complicated. And one manifestation of that is attacks against health facilities and health care workers.” He added that “two more of our colleagues, trying to be part of the solution,” were killed in the past few days before the meeting. “Therefore, security for the response is of absolutely paramount importance, and we are trying to strengthen the way the UN family supports the government’s own security.”

The third major difference from the West Africa outbreak, Mr. Lowcock pointed out, was the issue of money. There was more than $2 billion in international support available for that earlier response. However, “what we have available for us in the DRC is just a small fraction of that. Donors released funds early on ... but much more is needed.” He warned that the cost of reaching zero cases must not be underestimated, and that the fourth strategic response plan for this outbreak, currently under development, “will be budgeted at a much higher level than the previous three plans, and that’s because it’s our assessment that we need a bigger, more comprehensive response if we’re to get to zero cases than we’ve had hitherto.”

In fact, he said, “unless there is a big scale up in the response, we’re unlikely to get to zero cases.”

The meeting also featured speakers outlining more local aspects of the response and discussing how international workers were coordinating more and more with local authorities and health practitioners in order to deliver health care on the ground while attempting to avoid the distrust created in the past, while still ensuring security for foreign personnel.

Commenting on the issue of security, Rory Stewart, the United Kingdom’s Secretary of State for International Development, described how a major DRC Ebola treatment center was attacked and burned by military insurgents, but is now rebuilt. He said that, while there have been some improvements and reasons to be hopeful, “this isn’t a moment for complacency; [the situation] is literally on the knife-edge.” He added: “If you go into that treatment center now, you will see that, although there are very good medical procedures, there are really, really worrying security procedures. The entire protection for the medical staff consists of a small square of sandbags about the height of this table [he raised his hand just above the standard conference table he was sitting at], behind which the doctors and nurses are supposed to hide if armed men get into the compound.”

In his presentation, David Gressly, the UN Emergency Ebola Response Coordinator (speaking by video from the DRC), stressed the need to cooperate with local authorities and to build local trust, stating that “the UN is putting together a tight, disciplined, coordinated system for rapid response and operational adjustments so that we can shift from chasing the disease to getting ahead of it. We need to quickly detect cases ... that have moved into areas of risk to stop the transmission early.”

Matshidiso Moeti, MD, WHO Regional Director for Africa, added in her presentation: “We’ve identified nine high-risk countries. Among those, Burundi, South Sudan, and Uganda face the highest risk and require our concerted and continued efforts.” She said that more than 10,000 health care workers in areas of high risk have so far been vaccinated against the disease.

In his concluding statement, Dr. Kalenga described the current state of affairs in his country with a modicum of hope. “A community that has been told it has a case of Ebola is a community that is traumatized by the very announcement of this epidemic. With time, the community has learned to face up to this epidemic differently. In some villages we are given a very different welcome than before. ... The villagers ask: ‘What should we do to make sure the Ebola case is the only one? The first and the last one?’ Throughout this epidemic, we have seen the people become more aware, and a certain acceptance of the very difficult and lethal diagnosis. ... So we have seen that work in the community has been maturing and bearing fruit.”

However, he pointed out, “there is a whole debate around the area of vaccinations, and we do need to close down this debate. At this point in time, we have a vaccine that is highly effective, a vaccine that is accepted by the population, after whole periods of mistrust. So we’ve come to a point in time when the population is accepting a vaccine, a vaccine that works, so we decided to no longer open the debate on vaccines and vaccination. ....We don’t want contradictory messages going out here, we don’t want different schemes going out. ...We have an effective weapon, we have an effective molecule. Let’s focus on that. Let’s all go in the same direction,” he concluded.

On July 11, an announcement by DRC officials stated that Merck’s rVSV-ZEBOV would be the only vaccine that will be used during the current Ebola outbreak in North Kivu and Ituri provinces, and that no other clinical vaccine trials to be allowed in the country so as not to confuse the population.

In that same announcement, the DRC reported that, since the beginning of the epidemic, the cumulative number of Ebola cases was 2,451, of which 2,357 were confirmed and 94 probable. There were 1,647 deaths (1,553 confirmed and 94 probable) and 683 people who survived. An additional 364 suspected cases were under investigation.

Based on the target lesions with central epithelial disruption, the FP diagnosed erythema multiforme (EM) in this patient. He also diagnosed genital herpes simplex in the crusting stage and suspected that it was the inciting event for the EM.

EM is considered a hypersensitivity reaction that is often secondary to infections or medications. Herpes simplex viruses (HSVI and HSV2) are the most common causative agents and have been implicated in at least 60% of cases.

The patient did not know that she had genital herpes simplex but remembered having sores in the genital area that preceded the similar rash a year earlier. This was a case of recurrent EM responding to recurrent herpes simplex.

The patient suspected that she had genital herpes simplex on and off for the past 10 years but lacked health insurance, so she never visited a doctor for treatment. She recently obtained health insurance and was willing to be tested for other sexually transmitted diseases. She also wanted to have a test done to confirm this was herpes simplex. The FP explained that it was unlikely that an antiviral agent would help the current case of herpes simplex and the associated EM because of the late timing, but antiviral medication could help to prevent further outbreaks and decrease transmission to her husband.

The patient was enthusiastic to start valacyclovir 500 mg/d for prophylaxis. For symptomatic relief, the FP prescribed a 30-g tube of 0.1% triamcinolone appointment and instructed the patient to apply it to the EM twice daily. The patient was sent for blood tests for syphilis and HIV; fortunately, both came back negative. The herpes simplex PCR test was positive for HSV2.

On a 1-week follow-up visit, the skin lesions were resolving, and the patient had no further symptoms. The patient said she understood that she should refrain from sexual intercourse if she developed lesions while on prophylaxis.

The FP explained that it was unlikely that an antiviral agent would help the current case of herpes simplex and the associated EM because of the late timing, but antiviral medication could help to prevent further outbreaks and decrease transmission to her husband.

The patient was enthusiastic to start valacyclovir 500 mg/d for prophylaxis. For symptomatic relief, the FP prescribed a 30-g tube of 0.1% triamcinolone appointment and instructed the patient to apply it to the EM twice daily. The patient was sent for blood tests for syphilis and HIV; fortunately, both came back negative. The herpes simplex PCR test was positive for HSV2.

On a 1-week follow-up visit, the skin lesions were resolving, and the patient had no further symptoms. The patient said she understood that she should refrain from sexual intercourse if she developed lesions while on prophylaxis.

Based on the target lesions with central epithelial disruption, the FP diagnosed erythema multiforme (EM) in this patient. He also diagnosed genital herpes simplex in the crusting stage and suspected that it was the inciting event for the EM.

EM is considered a hypersensitivity reaction that is often secondary to infections or medications. Herpes simplex viruses (HSVI and HSV2) are the most common causative agents and have been implicated in at least 60% of cases.

The patient did not know that she had genital herpes simplex but remembered having sores in the genital area that preceded the similar rash a year earlier. This was a case of recurrent EM responding to recurrent herpes simplex.

By measuring parents’ attitudes regarding disease salience and community benefit, high scores on a four-item scale was associated with fivefold greater likelihood of not fully vaccinating their children, according to a study published in the Pediatric Infectious Disease Journal.

Steve Mann/Thinkstock

Mohammad Tahir Yousafzai, MPH, of Aga Khan University, Karachi, Pakistan, and colleagues developed a larger 14-item scale to measure parental attitudes and surveyed 901 households in the Sindh province of Pakistan during 2014. Part of this scale was a short 4-item subscale focusing on disease salience and community benefit, whereas the remaining 10 items form another subscale that measures parents’ perceptions and concerns regarding vaccines directly. The items are presented as 1-5 Likert scales, and scoring higher represents holding more negative attitudes regarding vaccines.

Of the 901 households surveyed, 25% of children were fully vaccinated, which meant children received all primary vaccines up to 14 weeks of age, and 54% were partially vaccinated, which meant at least one of those primary vaccines had been missed. The remaining 21% were unvaccinated.

High scores on the full 14-item scale showed some correlation with no vaccination versus partial or full vaccination (odds ratio, 3.05; 95% confidence interval, 1.75-5.31); the association disappeared after adjustment for children’s age and gender. The subscales performed better after adjustment: The adjusted ORs were 1.52 (95% CI, 1.05-2.21) for the longer subscale and 5.21 (95% CI, 3.60-7.55) for the shorter subscale. The data also showed high association between high scores on the shorter subscale and the likelihood of no or only partial vaccination (aOR, 9.65; 95% CI, 4.81-19.37).

The researchers noted that most similar scales used in developed countries are longer (10 or more items) and have lower internal consistency. This four-item scale, on the other hand, may be especially useful among lower-income populations and those in developing areas that have lower literacy rates.

One of the limitations of the study was that it was conducted only in Pakistan and not multiple developing countries; the researchers acknowledged this could limit generalizability. Another limitation is that the study size was too small for subdomain analysis; the researchers wrote that, although a lack of such analysis is unfortunate, it shouldn’t hamper the shorter subscale’s usability. A further limitation is that there was little variability across Likert scores – mostly answers at the extreme ends rather than a mix. This suggests that interviewees may not have understood how Likert scales work and therefore may not have answered accurately, noted the researchers, who employed a visual chart, trained interviewers, and field monitoring to mitigate this possibility.

“Measurement of the parental attitudes toward childhood vaccination is very important for the appropriate planning of strategies for increasing vaccine coverage and for monitoring,” they wrote.

The study was sponsored by Gavi, The Vaccine Alliance. The authors had no funding or conflicts of interest to disclose.

The Food and Drug Administration has approved Recarbrio for the treatment of complicated urinary tract infections (cUTI) and complicated intra-abdominal infections (cIAI) in adults. Recarbrio is a three-drug combo injection containing imipenem/cilastatin, an antibiotic previously approved by the FDA, and relebactam, a beta-lactamase inhibitor.

The efficacy of Recarbrio was supported by data on the efficacy of imipenem/cilastatin in the treatment of cUTI and cIAI and by in vitro studies and animal models of infection with treatment by relebactam. The safety was assessed in a pair of clinical studies, one that assessed cUTI patients and another that assessed cIAI patients.

The most common adverse events reported were nausea, diarrhea, headache, fever, and increased liver enzymes. Treatment with Recarbrio is not recommended in patients taking ganciclovir, valproic acid, or divalproex sodium because there is an increased risk of seizures, according to the FDA.

“The FDA remains focused on facilitating the development of safe and effective new antibacterial drugs to give patients more options to fight serious infections. It is important that the use of Recarbrio be reserved for situations when there are limited or no alternative antibacterial drugs for treating a patient’s infection,” Ed Cox, MD, MPH, director for the Office of Antimicrobial Products in FDA’s Center for Drug Evaluation and Research, said in the press release.

Children whose mothers were exposed to the pandemic H1N1 influenza vaccine during pregnancy do not have notably different health outcomes at the age of 5 years, according to Laura K. Walsh of the University of Ottawa and associates.

Piotr Marcinski/Thinkstock

The investigators conducted a population-based retrospective cohort study from November 2009 to October 2010 of all live births within the province of Ontario. Of the 104,249 eligible live births reported to the Ontario birth registry, 31,295 were exposed to the H1N1 vaccine in utero. After adjustment, there were no significant differences in the women who did and did not receive vaccines during pregnancy, according to the study, published in the BMJ.

After a median follow-up of 5 years, 14% of children received an asthma diagnosis, with a median age at diagnosis of 1.8 years. Children were more likely to receive an asthma diagnosis if their mothers had a preexisting condition or if they were born preterm. At follow-up, 34% of children had at least one upper respiratory tract infection. Sensory disorder, neoplasm, and pediatric complex chronic condition were rare, each occurring in less than 1% of the study cohort (BMJ. 2019 Jul 10. doi: 10.1136/bmj.l4151).

No significant association was found between prenatal exposure to the H1N1 vaccine and upper or lower respiratory infections, otitis media, all infections, neoplasms, sensory disorders, rates of urgent and inpatient health services use, pediatric complex chronic conditions, or mortality. A weak but significant association was observed for asthma (adjusted hazard ratio, 1.05; 95% confidence interval, 1.02-1.09), and a weak inverse association was found for gastrointestinal infections (adjusted incidence rate ratio, 0.94; 95% CI, 0.91-0.98).

“Although we observed a small, but statistically significant, increase in pediatric asthma and a reduction in gastrointestinal infections, we are not aware of any biologic mechanisms to explain these findings. Future studies in different settings and with different influenza vaccine formulations will be important for developing the evidence base on longer-term pediatric outcomes following influenza vaccination during pregnancy,” the investigators concluded.

The study was funded by grants from the Canadian Institutes of Health Research and the Institute for Clinical Evaluative Sciences.

The United States continues to slowly add new cases of measles to 2019’s postelimination-record total, but California was officially removed from the outbreak list this week, according to the Centers for Disease Control and Prevention.

There were 14 new measles cases reported during the week ending July 11, bringing the total for the year to 1,123 in 28 states, the CDC reported July 15. That is the highest number of cases reported since measles was declared eliminated in 2000 and the most in a single year since 1992.

The end of outbreak-related activity in California leaves three locations still dealing with ongoing cases: Rockland County, N.Y.; New York City; and King, Pierce, and Snohomish Counties in Washington, the CDC said.

Those three jurisdictions currently report the following:

• reported four new cases from July 3 to July 11 and is up to 175 cases for the year.
• had one new case from July 1 to July 8 and is now at 564 for the year.
• reported two cases from July 1 to July 10 and is now at 10 for the year (the other two counties have a total of three cases). Clark County in Washington reported 71 cases in an earlier, unrelated outbreak.

AUSTIN, TEX. – The majority of skin-related pediatric inpatient admissions in the United States involve treatment for cellulitis, results from a large study of national data showed.

“Skin conditions significantly affect pediatric inpatients, and dermatologists ought be accessible for consultation to enhance care and costs,” the study’s first author, Marcus L. Elias, said in an interview prior to the annual meeting of the Society for Pediatric Dermatology.

According to Mr. Elias, who is a 4th-year medical student at Rutgers New Jersey Medical School–Newark, few national studies on skin diseases for pediatric inpatients have been published in the medical literature. Earlier this year, researchers examined inpatient dermatologic conditions in patients aged 18 years and older (J Am Acad Dermatol 2019;80[2]:425-32), but Mr. Elias and associates set out to analyze the burden of inpatient pediatric dermatologic conditions on a national basis. “We wanted to see if the same conditions that were hospitalizing adults were also hospitalizing kids,” he said. “We found that this was indeed the case.”

The researchers queried the National Inpatient Sample database for all cases involving patients aged 18 years and younger during 2001-2013. The search yielded a sample of 16,837,857 patients. From this, the researchers analyzed diagnosis-related groups for dermatologic conditions denoting the principal diagnosis at discharge, which left a final sample of 84,090 patients. Frequency and chi-squared tests were used to analyze categorical variables.

More than half of patients (54%) were male, 36% were white, 48% had Medicaid insurance, and 43% had private insurance. Mr. Elias reported that the median length of stay for patients was 2 days and the median cost of care was $6,289.50 for each case. More than three-quarters of pediatric inpatients with dermatologic diagnoses were treated for “cellulitis” (66,147 cases, or 79%), with most cases involving the legs (16,875 cases, or 20%). Other pediatric inpatients were admitted for “minor skin disorder without complications” (5,458 cases, or 7%), and “minor skin disorder with complications” (2,822 cases, or 3%). A total of 64 patients died during the study period. Of these, 31 cases (50%) involved “skin graft and/or debridement of skin ulcer or cellulitis without complications,” the study found.

“We were surprised that the major cause of mortality for our patients was classified as ‘skin graft and/or debridement of skin ulcer or cellulitis without complications,’ as a similar diagnosis-related groupings exist denoting that complications did arise,” Mr. Elias said. “Still, it is not possible for us to determine if the mortality was from the skin graft/debridement or another cause entirely. It is possible that the procedure was without complications, only to have the patient succumb to an ancillary process.”

He acknowledged certain limitations of the study, including the fact that the function of dermatologic consults for hospitalized patients was not examined. “We also cannot draw conclusions as to whether improved outpatient therapy reduces the need for hospitalization,” he said. Mr. Elias reported having no financial disclosures.

“We were surprised that the major cause of mortality for our patients was classified as ‘skin graft and/or debridement of skin ulcer or cellulitis without complications,’ as a similar diagnosis-related groupings exist denoting that complications did arise,” Mr. Elias said. “Still, it is not possible for us to determine if the mortality was from the skin graft/debridement or another cause entirely. It is possible that the procedure was without complications, only to have the patient succumb to an ancillary process.”

He acknowledged certain limitations of the study, including the fact that the function of dermatologic consults for hospitalized patients was not examined. “We also cannot draw conclusions as to whether improved outpatient therapy reduces the need for hospitalization,” he said. Mr. Elias reported having no financial disclosures.

AUSTIN, TEX. – The majority of skin-related pediatric inpatient admissions in the United States involve treatment for cellulitis, results from a large study of national data showed.

“Skin conditions significantly affect pediatric inpatients, and dermatologists ought be accessible for consultation to enhance care and costs,” the study’s first author, Marcus L. Elias, said in an interview prior to the annual meeting of the Society for Pediatric Dermatology.

According to Mr. Elias, who is a 4th-year medical student at Rutgers New Jersey Medical School–Newark, few national studies on skin diseases for pediatric inpatients have been published in the medical literature. Earlier this year, researchers examined inpatient dermatologic conditions in patients aged 18 years and older (J Am Acad Dermatol 2019;80[2]:425-32), but Mr. Elias and associates set out to analyze the burden of inpatient pediatric dermatologic conditions on a national basis. “We wanted to see if the same conditions that were hospitalizing adults were also hospitalizing kids,” he said. “We found that this was indeed the case.”

The researchers queried the National Inpatient Sample database for all cases involving patients aged 18 years and younger during 2001-2013. The search yielded a sample of 16,837,857 patients. From this, the researchers analyzed diagnosis-related groups for dermatologic conditions denoting the principal diagnosis at discharge, which left a final sample of 84,090 patients. Frequency and chi-squared tests were used to analyze categorical variables.

More than half of patients (54%) were male, 36% were white, 48% had Medicaid insurance, and 43% had private insurance. Mr. Elias reported that the median length of stay for patients was 2 days and the median cost of care was $6,289.50 for each case. More than three-quarters of pediatric inpatients with dermatologic diagnoses were treated for “cellulitis” (66,147 cases, or 79%), with most cases involving the legs (16,875 cases, or 20%). Other pediatric inpatients were admitted for “minor skin disorder without complications” (5,458 cases, or 7%), and “minor skin disorder with complications” (2,822 cases, or 3%). A total of 64 patients died during the study period. Of these, 31 cases (50%) involved “skin graft and/or debridement of skin ulcer or cellulitis without complications,” the study found.

Patients with chronic obstructive pulmonary disease are at a significantly increased risk for hospitalization for community-acquired pneumonia (CAP), compared with patients without COPD, a large prospective study has found.

Jose Bordon, MD, and colleagues aimed to define incidence and outcomes of COPD patients hospitalized with pneumonia in the city of Louisville, Ky., and to extrapolate the burden of disease in the U.S. population. They conducted a secondary analysis of data from the University of Louisville Pneumonia Study, a prospective population-based cohort study of all hospitalized adults with CAP who were residents in the city of Louisville, Ky., from June 1, 2014, to May 31, 2016.

COPD prevalence in the city of Louisville was derived via data from the 2014 Behavioral Risk Factor Surveillance System (BRFSS) as well as from the 2014 National Health Interview Survey (NHIS). In addition, the researchers analyzed clinical outcomes including time to clinical stability (TCS), length of hospital stay (LOS), and mortality, according to Dr. Bordon, an infectious disease specialist at Providence Health Center, Washington, and colleagues on behalf of the University of Louisville Pneumonia Study Group.

The researchers found an 18-fold greater incidence of community-acquired pneumonia in patients with COPD, compared with non-COPD patients.

A total of 18,246 individuals aged 40 and older with COPD were estimated to live in Louisville, Ky. The researchers found that 3,419 COPD patients were hospitalized due to CAP in Louisville during the 2-year study period. COPD patients, compared with non-COPD patients, were more likely to have a history of heart failure, more ICU admissions, and use of mechanical ventilation, compared with patients without COPD. The two groups had similar pneumonia severity index scores, and 17% received oral steroids prior to admission. COPD patients had more pneumococcal pneumonia, despite receiving pneumococcal vaccine significantly more often than non-COPD patients.

The annual incidence of hospitalized CAP was 9,369 cases per 100,000 COPD patients in the city of Louisville. In the same period, the incidence of CAP in patients without COPD was 509 per 100,000, a more than 18-fold difference.

Although the incidence of CAP in COPD patients was much higher than in those without, the difference didn’t appear to have an impact on clinical outcomes. There were no clinical differences among patients with vs. without COPD in regard to time to reach clinical improvement and time of hospital discharge, and in-hospital mortality was not statistically significantly different between the groups, the authors reported. The mortality of COPD patients during hospitalization, at 30 days, at 6 months, and at 1 year was 5.6% of patients, 11.9%, 24.3%, and 33.0%, respectively vs. 6.6%, 14.2%, 24.2%, and 30.1% in non-COPD patients. However, 1-year all-cause mortality was a significant 25% greater among COPD patients, as might be expected by the progression and effects of the underlying disease.

“[Our] observations mean that nearly 1 in 10 persons with COPD will be hospitalized annually due to CAP. This translates into approximately 500,000 COPD patients hospitalized with CAP every year in the U.S., resulting in a substantial burden of approximately 5 billion U.S. dollars in hospitalization costs,” the researchers stated.

“Modifiable factors associated with CAP such as tobacco smoking and immunizations should be health interventions to prevent the burden of CAP in COPD patients,” even though “pneumococcal vaccination was used more often in the COPD population than in other CAP patients, but pneumococcal pneumonia still occurred at a numerically higher rate,” they noted.

The study was supported by the University of Louisville, Ky., with partial support from Pfizer. The authors reported having no conflicts.
