Rituximab boosts survival in primary CNS lymphoma
For patients with primary central nervous system lymphoma (PCNSL), adding rituximab to combination high-dose methotrexate and temozolomide significantly boosted the 5-year overall survival rate, according to a retrospective study.
The triplet combination could be a safe and effective first-line option for patients with PCNSL, particularly the frail and elderly, who may have issues with toxicity when receiving current standard care, reported lead author Cui Chen, MD, of Sun Yat-Sen University Cancer Center in Guangzhou, China, and his colleagues.
“An increasing number of studies and meta‐analyses have investigated the effect of rituximab in PCNSL, indicating that rituximab can robustly enhance the response rate and possibly improve survival,” the investigators wrote in Cancer Medicine. “However, data regarding the addition of rituximab to [methotrexate and temozolomide] for PCNSL are limited, and no study has directly compared the efficacy of [rituximab/high-dose methotrexate/temozolomide] to that of [high-dose methotrexate/temozolomide].”
The study involved 62 patients with untreated PCNSL who were diagnosed between 2005 and 2015. Out of the 62 patients, 32 received rituximab/high-dose methotrexate/temozolomide (RMT) and 30 received high-dose methotrexate/temozolomide (MT). Patients received up to eight cycles of therapy, with discontinuation upon disease progression or toxicity.
The results showed that patients treated with RMT had significantly better outcomes than those who received MT, first marked by objective response rates, which were 93.7% for RMT and 69.0% for MT.
Survival rates also showed the advantage of rituximab. For the RMT group, 2-year and 5-year progression-free survival rates were 81.3% and 53.3%, respectively, compared with 46.5% and 29.1% for patients receiving MT.
Most importantly, rituximab boosted overall survival to a significant and notable extent, with higher rates at 2 years (82.3% vs. 65.7%) and 5 years (82.3% vs. 50.0%).
Efficacy did not diminish safety, as no significant differences in toxicity were found between treatment types. The most common grade 3-4 toxicities were hematologic; most commonly, this entailed neutropenia, which occurred in about one-quarter of patients.
“Given its outstanding efficacy and favorable toxicity, we consider RMT to be a feasible and safe therapeutic approach as a first‐line treatment for PCNSL. Moreover, RMT is an ideal regimen for elderly patients and frail populations who may not tolerate [whole‐brain radiation therapy] or [autologous stem‐cell transplantation],” the researchers wrote.
The study was funded by the Natural Science Foundation of Guangdong Province. The researchers reported having no conflicts of interest.

Cirrhosis model predicts decompensation across diverse populations
A prognostic model that uses serum albumin-bilirubin (ALBI) and Fibrosis-4 (FIB-4) scores can identify patients with cirrhosis who are at high risk of liver decompensation, according to investigators.
During validation testing, the scoring system performed well among European and Middle Eastern patients, which supports prognostic value across diverse populations, reported lead author Neil Guha, MRCP, PhD, of the University of Nottingham (U.K.) and his colleagues, who suggested that the scoring system could fix an important practice gap.
“Identification of patients [with chronic liver disease] that need intensive monitoring and timely intervention is challenging,” the investigators wrote in Clinical Gastroenterology and Hepatology. “Robust prognostic tools using simple laboratory variables, with potential for implementation in nonspecialist settings and across different health care systems, have significant appeal.”
Although existing scoring systems have been used for decades, they have clear limitations, the investigators noted, referring to predictive ability that may be too little, too late.
“[T]hese scoring systems provide value after synthetic liver function has become significantly deranged and provide only short-term prognostic value,” the investigators wrote. “Presently, there are no scores, performed in routine clinical practice, that provide robust prognostic stratification within early, compensated cirrhosis over the medium/long term.”
To fulfill this need, the investigators developed and validated a prognostic model that incorporates data from the ALBI and FIB-4 scoring systems because these tests measure both fibrosis and function. The development phase involved 145 patients with compensated cirrhosis from Nottingham. Almost half of the cohort had liver disease because of alcohol (44.8%), while about one out of three patients had nonalcoholic fatty liver disease (29.7%). After investigators collected baseline clinical features and scores, patients were followed for a median of 4.59 years, during which time decompensation events were recorded (ascites, variceal bleeding, and encephalopathy). Decompensation occurred in about one out of five patients (19.3%) in the U.K. group, with ascites being the most common (71.4%). Using these findings, the investigators created the prognostic model, which classified patients as having either low or high risk of decompensation. In the development cohort, patients with high risk scores had a hazard ratio for decompensation of 7.10.
In the second part of the study, the investigators validated their model with two clinically distinct groups in Dublin, Ireland (prospective; n = 141), and Menoufia, Egypt (retrospective; n = 93).
In the Dublin cohort, the most common etiologies were alcohol (39.7%) and hepatitis C (29.8%). Over a maximum observational period of 6.4 years, the decompensation rate was lower than the development group, at 12.1%. Types of decompensation also differed, with variceal bleeding being the most common (47.1%). Patients with high risk scores had a higher HR for decompensation than the U.K. cohort, at 12.54.
In the Egypt group, the most common causes of liver disease were nonalcoholic fatty liver disease (47.3%) and hepatitis C (34.4%). The maximum follow-up period was 10.6 years, during which time 38.7% of patients experienced decompensation, with ascites being the most common form (57.1%). The HR of 5.10 was the lowest of all cohorts.
The investigators noted that the cohorts represented unique patient populations with different etiological patterns. “This provides reassurance that the model has generalizability for stratifying liver disease at an international level,” the investigators wrote, suggesting that ALBI and FIB-4 can be used in low-resource and community settings.
“A frequently leveled criticism of algorithms such as ALBI-FIB-4 is that they are too complicated to be applied routinely in the clinical setting,” the investigators wrote. “To overcome this problem we developed a simple online calculator which can be accessed using the following link: https://jscalc.io/calc/gdEJj89Wz5PirkSL.”
“We have shown that routinely available laboratory variables, combined in a novel algorithm, ALBI-FIB-4, can stratify patients with cirrhosis for future risk of liver decompensation,” the investigators concluded. “The ability to do this in the context of early, compensated cirrhosis with preserved liver synthetic function whilst also predicting long-term clinical outcomes has clinical utility for international health care systems.”
The study was funded by National Institute for Health Research (NIHR) Nottingham Digestive Diseases Biomedical Research Centre based at Nottingham University Hospitals NHS Trust and the University of Nottingham. The investigators declared no conflicts of interest.

Worse survival seen among black patients with MCL
Black non-Hispanic patients with mantle cell lymphoma (MCL) have a lower rate of 5-year overall survival, compared with white non-Hispanic and Hispanic patients, according to a retrospective analysis of more than 18,000 cases.
However, black patients were also most likely to receive treatment at an academic center, which was an independent predictor of better survival, reported Nikesh N. Shah, MD, of Emory University, Atlanta, and his colleagues. This finding suggests that even academic centers still need to focus on overcoming demographic disparities.
“Racial and socioeconomic differences have been reported in many malignancies and certain lymphomas; however, few studies report on disparities in MCL,” the investigators wrote in Clinical Lymphoma, Myeloma & Leukemia. “To our knowledge this is the first such study to assess racial and socioeconomic disparities in this disease.”
The investigators reviewed 18,120 patients with MCL diagnosed between 2004 and 2013; data were drawn from the National Cancer Database. The primary endpoint was overall survival from the time of diagnosis, with analyses conducted to assess various associations with race/ethnicity, facility type, clinical/tumor characteristics, cancer stage, insurance type, and other factors.
Results showed that Hispanic patients had the highest rate of overall survival, at 55.8%, followed by white patients, at 50.1%. Trailing behind these groups were black patients (46.8%) and patients of other races/ethnicities (46.0%).
Along with survival disparities, race/ethnicity was tied to certain clinical and treatment characteristics. Compared with white patients, black patients were more likely to experience B symptoms (28% vs. 25%) and have Medicaid or lack insurance (15% vs. 5%). Black and Hispanic patients were also less likely than white non-Hispanic patients to receive stem cell transplant (13% vs. 10% vs. 10%).
Although black patients were more likely than white patients to receive treatment at an academic center (51% vs. 38%), a factor independently associated with best survival among center types, whatever advantage provided apparently did not exceed disadvantages associated with race.
“We report inferior overall survival in black patients after accounting for socioeconomic status, as seen in other malignancies,” the investigators wrote. “Surprisingly, these patients were more likely to be treated at academic centers, which independently showed improved overall survival in multivariable analysis that controlled for age, disease stage, insurance status, and other socioeconomic factors.”
The researchers cited a number of steps that could help close the survival gap, including providing more comprehensive supportive care between physician visits and enrollment of patients from diverse racial background on clinical trials.

Infant survival rate after HCT remains flat
High rates of relapse and toxicities among infants who undergo allogeneic hematopoietic cell transplant (allo-HCT) contribute to survival rates that have remained largely unchanged from 2000-2014, based on a retrospective study of almost 2,500 cases.
Although survival rates improved from 2000 to 2004 among children aged 1 and younger who underwent allo-HCT for nonmalignant conditions, rates plateaued thereafter, reported lead author Suhag H. Parikh, MD, of Duke University Medical Center in Durham, North Carolina, and his colleagues. Still more disappointing, survival rates for infants with malignant conditions remained relatively flat throughout the 15-year study period.
For adult patients, allo-HCT survival rates have improved over time, but data for infants are rare. This is a concerning blind spot because infants are a particularly vulnerable population in the transplant setting.
“Infants may be at higher risk for toxicities than adults,” the investigators wrote in JAMA Pediatrics. “Although children are considered to have better tolerance to high-intensity or myeloablative conditioning regimens and perhaps better immune reconstitution owing to a functional thymus, infants may be at higher risk of transplant-associated complications.”
The present study involved 2,498 infants,1 year old or younger (median age 7 months), who underwent allo-HCT for malignant or nonmalignant conditions between 2000 and 2014. Information was drawn from The Center for International Blood and Marrow Transplant Research (CIBMTR), which consists of data from more than 450 transplant centers across the world.
The investigators assessed overall survival trends among infants undergoing allo-HCT; in addition, they analyzed factors contributing to mortality and rates of two major organ toxicities: sinusoidal obstruction syndrome and idiopathic pneumonia syndrome. Cases were divided into 2 cohorts: malignant and nonmalignant. Time-analysis was divided into three periods: 2000-2004, 2005-2009, and 2010-2014.
Overall, the results were disheartening. Survival trends were generally flat during the 15-year study period, and some outcomes actually worsened over time. As a small highlight, infants with nonmalignant disease had improved survival when comparing the second and third time period with the first time period (HR, 0.77; P = .007); however, this trend fell flat after 2004. Three-year overall survival rates for infants with nonmalignant disease from least recent to most recent time period, were 65.0%, 72.0%, and 74.0%.
Survival was poorer with malignant conditions, with 3-year overall survival rates of 54.8%, 64.6%, and 58.9% from least recent to most recent time period. This trend was associated with a worsening relapse rate, which increased from 19% to 36% from 2000 to 2014.
Also, toxicities were relatively common. Sinusoidal obstruction syndrome occurred in 32% of infants with malignant disease and in 13% with nonmalignant conditions. The rate of interstitial pneumonia syndrome at 100 days post-transplant was 5% across all patients.
Optimal supportive care and donor/graft selection might improve outcomes, as could reduced-intensity/nonmyeloablative conditioning regimens rather than total body irradiation, according to the researchers.
Changes in practice for disease subgroups may be warranted, based on the improved survival rate seen for infants with nonmalignant disease, which was mostly driven by better outcomes in patients with severe combined immunodeficiency, a disease subgroup that has had newborn-screening programs since 2008. Judging by the trends, such programs are truly making a difference, the researchers wrote.
The study was funded by the National Cancer Institute (NCI); the National Heart, Lung and Blood Institute (NHLBI); Health Resources and Services Administration; the Office of Naval Research; and a number of private pharmaceutical companies. The investigators reported financial relationships with Sangamo Therapeutics, Mallinckrodt, Takeda, Jazz, and others.

High rates of relapse and toxicities among infants who undergo allogeneic hematopoietic cell transplant (allo-HCT) contribute to survival rates that have remained largely unchanged from 2000-2014, based on a retrospective study of almost 2,500 cases.
Although survival rates improved from 2000 to 2004 among children aged 1 and younger who underwent allo-HCT for nonmalignant conditions, rates plateaued thereafter, reported lead author Suhag H. Parikh, MD, of Duke University Medical Center in Durham, North Carolina, and his colleagues. Still more disappointing, survival rates for infants with malignant conditions remained relatively flat throughout the 15-year study period.
For adult patients, allo-HCT survival rates have improved over time, but data for infants are rare. This is a concerning blind spot because infants are a particularly vulnerable population in the transplant setting.
“Infants may be at higher risk for toxicities than adults,” the investigators wrote in JAMA Pediatrics. “Although children are considered to have better tolerance to high-intensity or myeloablative conditioning regimens and perhaps better immune reconstitution owing to a functional thymus, infants may be at higher risk of transplant-associated complications.”
The present study involved 2,498 infants,1 year old or younger (median age 7 months), who underwent allo-HCT for malignant or nonmalignant conditions between 2000 and 2014. Information was drawn from The Center for International Blood and Marrow Transplant Research (CIBMTR), which consists of data from more than 450 transplant centers across the world.
The investigators assessed overall survival trends among infants undergoing allo-HCT; in addition, they analyzed factors contributing to mortality and rates of two major organ toxicities: sinusoidal obstruction syndrome and idiopathic pneumonia syndrome. Cases were divided into 2 cohorts: malignant and nonmalignant. Time-analysis was divided into three periods: 2000-2004, 2005-2009, and 2010-2014.
Overall, the results were disheartening. Survival trends were generally flat during the 15-year study period, and some outcomes actually worsened over time. As a small highlight, infants with nonmalignant disease had improved survival when comparing the second and third time period with the first time period (HR, 0.77; P = .007); however, this trend fell flat after 2004. Three-year overall survival rates for infants with nonmalignant disease from least recent to most recent time period, were 65.0%, 72.0%, and 74.0%.
Survival was poorer with malignant conditions, with 3-year overall survival rates of 54.8%, 64.6%, and 58.9% from least recent to most recent time period. This trend was associated with a worsening relapse rate, which increased from 19% to 36% from 2000 to 2014.
Also, toxicities were relatively common. Sinusoidal obstruction syndrome occurred in 32% of infants with malignant disease and in 13% with nonmalignant conditions. The rate of interstitial pneumonia syndrome at 100 days post-transplant was 5% across all patients.

MitraClip improves survival and health status for at least 2 years
, based on results from a substudy of the COAPT trial.
Significant improvements seen at 1 month in the TMVr group had waned only slightly by the 2-year time point, reported lead author Suzanne V. Arnold, MD, of Saint Luke’s Mid America Heart Institute and University of Missouri–Kansas City, who presented the findings at the annual meeting of the American College of Cardiology. The study was simultaneously published in the Journal of the American College of Cardiology.
“Considering the previously reported benefits of TMVr on survival and heart failure hospitalization, these health status findings further support the device as a valuable treatment option for heart failure patients with severe secondary mitral regurgitation who remain symptomatic despite maximally-tolerated guideline-directed medical therapy,” Dr. Arnold and her colleagues concluded.
Primary findings from the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) trial showed that TMVr reduced hospitalizations due to heart failure and all-cause mortality over 2 years, leading the Food and Drug Administration to grant an extended indication to MitraClip. With the present substudy, the investigators sought to learn more about impacts of TMVr on overall health.
“Beyond prolonging survival and reducing hospitalizations, improving patients’ health status (i.e., symptoms, functional status, quality of life) is a key treatment goal of TMVr,” the investigators wrote. “In fact, among older patients with comorbidities and high symptom burden, health status improvement may be of greater importance to patients than improved survival.”
To measure these outcomes, the investigators employed the Kansas City Cardiomyopathy Questionnaire (KCCQ) and the SF-36 health status survey, which they administered to 302 patients in the TMVr group and 312 patients in the standard care group. The primary endpoint was the KCCQ overall summary score (KCCQ-OS), which ranges from 0 to 100, with higher scores indicating better health status.
Across all patients, the average baseline KCCQ-OS score was 52.4 ± 23.0. After 1 month, the average KCCQ-OS score rose 2.1 points in the standard care group, while the TMVr group saw a 16.9-point increase, most heavily through the questionnaire’s quality of life domain. These figures translate to a mean between-group difference of 15.9 points, a value that decreased only slightly after 2 years, to 12.8 points. Further suggesting that TMVr had beneficial and lasting effects, a significantly greater percentage of patients in the TMVr group than in the standard care group were alive with a moderately large health improvement after 2 years (36.4% vs 16.6%; P less than .001).
The study was funded by Abbott Vascular. Several of the investigators reported financial relationships with Abbott as well as Novartis, Bayer, V-wave, Corvia, and others.

Ovarian cancer survivors carry burden of severe long-term fatigue
Women who have survived epithelial ovarian cancer (EOC) more often report severe long-term fatigue than healthy women, according to a case-control study involving more than 600 individuals.
Ovarian cancer survivors had a higher rate of sleep disturbance, neuropathy, and depression, reported lead author Florence Joly, MD, of Centre François Baclesse in Caen, France, and her colleagues. These factors likely contribute to severe long-term fatigue; a condition that has been minimally researched in EOC survivors.
“Long-term fatigue has been described as one of the most common and distressing adverse effects of cancer and its treatment,” the investigators wrote in Annals of Oncology. However, “Little is known about the prevalence of long-term fatigue in EOC survivors several years after treatment in comparison with age-matched healthy women.”
The study involved 318 EOC survivors who had not relapsed for at least 3 years, and 318 age-matched, healthy women. Survivors were 63 years old, on average, and split almost evenly between cases of early and advanced disease (50% stage I/II vs. 48% stage III/IV). Almost all patients had received platinum/taxane chemotherapy (99%). Average follow-up was 6 years.
Participants self-reported through questionnaires about physical activity (International Physical Activity Questionnaire), sleep disturbance ( Insomnia Severity Index), anxiety/depression (Hospital Anxiety and Depression Scale), neuropathy (Functional Assessment of Cancer Therapy-Taxane Neurotoxicity [FACT-Ntx]), quality of life ( Functional Assessment of Cancer Therapy-General/Ovarian), and fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). Severe long-term fatigue was defined as a FACIT-F score of less than 37. Analysis was performed to find rates of severe long-term fatigue and contributing factors.
Although sociodemographic measures and global quality of life were similar between groups, 26% of EOC survivors reported severe long-term fatigue, compared with 13% of healthy women (P = .0004). Multivariable analysis revealed that three main factors contributed to this trend; worse neuropathy scores (FACT-Ntx 35 vs. 39), higher rates of depression (22% vs. 13%), and lower sleep quality (63% vs. 47%).
“These results highlight the need for continuous screening of sleep disturbance and depression as soon as the diagnosis of EOC is made, and for sleep disturbance interventions in EOC survivors,” the investigators wrote. “As pharmacological treatment seems to have limited efficacy, behavioral interventions should be offered to improve sleep quality and/or depressive symptoms.”
“Fewer than 20% of our EOC survivors and controls exercised regularly, a finding consistent with a recent study conducted in long-term EOC survivors,” the investigators noted. “Personalized clinical exercise programs were effective in improving fatigue and depression in a heterogeneous population of cancer survivors, so they should be promoted in EOC survivors [too].”
The study was funded by Fondation de France. The investigators disclosed financial relationships with AstraZeneca, Janssen, Sanofi, Novartis, and others.

Weekly turoctocog alfa pegol is feasible for hemophilia A
FROM HAEMOPHILIA
Some patients with severe hemophilia A can be managed with weekly injections of the recombinant factor VIII (rFVIII) product turoctocog alfa pegol (N8-GP), based on results from an extension of the pathfinder 2 trial.
In patients who had two or fewer bleeding episodes during the preceding 6 months, N8-GP was effective for prophylaxis and treating bleeding episodes without causing inhibitor development, reported lead author Nicola Curry, MD, of the Oxford (England) Haemophilia and Thrombosis Centre at Churchill Hospital and her colleagues.
The trial exemplifies an ongoing effort to reduce frequency of prophylaxis in hemophilia A.
N8-GP, given every 4 days (or twice weekly in children), was approved by the Food and Drug Administration in February 2019; however, the investigators hypothesized that dose frequency could be stepped down in those who responded well to initial treatment.
“Many patients struggle to integrate prophylactic schedules into their daily lives, leading to missed injections and increased bleeding episodes,” the investigators wrote in a Haemophilia. “Therefore, prophylactic strategies offering effective haemostatic coverage with more convenient administration schedules are needed.”
To this end, the investigators identified 55 patients (at least 12 years old) from the pathfinder 2 trial who had two or fewer bleeding episodes during the preceding 6 months. From this group, 17 patients continued to receive 50 IU/kg of N8-GP every 4 days, as they had done during the main trial, while 38 patients received a higher dose – 75 IU/kg – every 7 days.
When necessary, N8-GP was used to treat bleeding episodes. Primary coendpoints were immunogenicity and efficacy, while all secondary endpoints were safety measures.
For both cohorts, median annualized bleeding rate (ABR) was 0.00 days, and greater than 50% of patients experienced no bleeds (53% every 4 days vs. 58% weekly). No inhibitors developed during the extension phase of the trial.
Along with strong support for weekly prophylaxis, N8-GP demonstrated efficiency in treating bleeding episodes; 87.5% of episodes were controlled with just one injection. This rate increased to 94.7% when including two or fewer injections.
During the study, 108 adverse events were reported in 65.5% of patients, although almost all were mild or moderate in severity, and unrelated to N8-GP. Five adverse events in five patients were related to treatment, including rash, headache, purpura, increased aspartate aminotransferase, and thrombocytopenia. No thromboembolic events were reported.
“These findings suggest that weekly N8-GP may provide effective prophylaxis with a reduced treatment burden for a selected subset of low-bleeding patients with severe haemophilia A,” the investigators wrote.
The study was funded by Novo Nordisk. The investigators reported financial relationships with Bayer, CSL, Novo Nordisk, Octapharma, Genentech, Shire, and others.

To this end, the investigators identified 55 patients (at least 12 years old) from the pathfinder 2 trial who had two or fewer bleeding episodes during the preceding 6 months. From this group, 17 patients continued to receive 50 IU/kg of N8-GP every 4 days, as they had done during the main trial, while 38 patients received a higher dose – 75 IU/kg – every 7 days.
When necessary, N8-GP was used to treat bleeding episodes. Primary coendpoints were immunogenicity and efficacy, while all secondary endpoints were safety measures.
For both cohorts, median annualized bleeding rate (ABR) was 0.00 days, and greater than 50% of patients experienced no bleeds (53% every 4 days vs. 58% weekly). No inhibitors developed during the extension phase of the trial.
Along with strong support for weekly prophylaxis, N8-GP demonstrated efficiency in treating bleeding episodes; 87.5% of episodes were controlled with just one injection. This rate increased to 94.7% when including two or fewer injections.
During the study, 108 adverse events were reported in 65.5% of patients, although almost all were mild or moderate in severity, and unrelated to N8-GP. Five adverse events in five patients were related to treatment, including rash, headache, purpura, increased aspartate aminotransferase, and thrombocytopenia. No thromboembolic events were reported.
“These findings suggest that weekly N8-GP may provide effective prophylaxis with a reduced treatment burden for a selected subset of low-bleeding patients with severe haemophilia A,” the investigators wrote.
The study was funded by Novo Nordisk. The investigators reported financial relationships with Bayer, CSL, Novo Nordisk, Octapharma, Genentech, Shire, and others.

Erectile dysfunction appears prevalent with hemophilia
Erectile dysfunction (ED) appears prevalent among men with hemophilia and becomes increasingly common with age, according to results from a recent survey.
Although the findings may not be generalizable because of small sample size (44 respondents), the survey offers a general sense of the sexual health of patients with hemophilia, which is a minimally researched topic, reported lead author Ming Yang, PhD, of the British Columbia Provincial Bleeding Disorders Program at St. Paul’s Hospital in Vancouver and colleagues.
Such data become increasingly important as new hemophilia therapies further extend the lifespan of patients, which thereby exposes them to diseases of old age, the investigators noted in Haemophilia.
Additionally, ED is considered an early sign of endothelial dysfunction in the general population, but data are lacking for patients with hemophilia.
Among the 56 men with hemophilia A or B who were surveyed with the International Index of Erectile Function (IIEF) questionnaire, 44 completed the survey (median age, 49 years). Specifically, respondents completed the “erectile function” component of the questionnaire because this is the only domain that has been validated.
To assess associations between ED and well-established risk factors, the investigators recorded prior surgeries, medications, atherosclerotic diseases, viral infections, and hemophilia-specific factors. To better characterize the population and look for other associations, the investigators had patients undergo baseline laboratory testing and measurements of blood pressure, anthropomorphic indexes, and endothelial function.
According to the IIEF, 38.6% of patients had ED, which was subcategorized as mild and mild to moderate in 4.5% of patients, moderate in 18.2%, and severe in 15.9%.
The investigators found significant associations between ED and coronary artery disease, hypertension, smoking, higher waist/hip ratio, homocysteine level, and age. However, on multivariable analysis, only age was correlated with ED domain score (P = .03). No associations between ED and endothelial dysfunction were reported.
While the findings may offer a rare look at ED rates in patients with hemophilia, they are insufficient for comparisons and generalizations, the investigators cautioned.
“Without comparative studies within the haemophilia population in Canada or elsewhere and due to limited sample size and non‐normalized distribution of our age group, this prevalence cannot reasonably be generalized to the entire haemophilia population,” the investigators wrote.
Instead, the investigators suggested that more studies are needed, especially ones involving customized questionnaires.
The study was funded by Pfizer. Dr. Yang reported having no conflicts of interest. One coauthor reported an unrestricted educational award from the Association of Hemophilia Clinic Directors of Canada/Baxter Canadian Hemostasis Fellowship, and another coauthor reported research funding from Pfizer.

Case report may link gluteal implants to lymphoma
Patients with textured silicone gluteal implants could be at risk of anaplastic large cell lymphoma, based on a possible case of ALCL in a patient diagnosed 1 year after implant placement.
The 49-year-old woman was initially diagnosed with anaplastic lymphoma kinase–negative ALCL via a lung mass and pleural fluid before bilateral gluteal ulceration occurred 1 month later, reported Orr Shauly of the University of Southern California in Los Angeles, and his colleagues.
Soft-tissue disease and fluid accumulation around the gluteal implants suggested that the lung mass had metastasized from primary neoplasia in the gluteal region. If ALCL did originate at the site of the gluteal implants, it would represent a first for silicone implant–associated ALCL, which has historically been associated exclusively with breast implants.
“As many as 200 cases of [breast implant-associated ALCL] have been described worldwide, with a majority in the context of cosmetic primary breast augmentation or cancer-related breast reconstruction with the use of a textured implant (57% of all cases),” the investigators wrote in Aesthetic Surgery Journal. “Recently however, it has been hypothesized that the relationship of ALCL with the placement of textured silicone implants may not [be] limited to the breast due to its multifactorial nature and association with texturization of the implant surface.”
During the initial work-up, a CT showed fluid collection and enhancement around the gluteal implants. Following ALCL diagnosis via lung mass biopsy and histopathology, the patient was transferred to a different facility for chemotherapy. When the patient presented 1 month later to the original facility with gluteal ulceration, the oncology team suspected infection; however, all cultures from fluid around the implants were negative.
Because of the possibility of false-negative tests, the patient was started on a regimen of acyclovir, vancomycin, metronidazole, and isavuconazole. Explantation was planned, but before this could occur, the patient deteriorated rapidly and died of respiratory and renal failure.
ALCL was not confirmed via cytology or histopathology in the gluteal region, and the patient’s family did not consent to autopsy, so a definitive diagnosis of gluteal implant–associated ALCL remained elusive.
“In this instance, it can only be concluded that the patient’s condition may have been associated with placement of textured silicone gluteal implants, but [we] still lack evidence of causation,” the investigators wrote. “It should also be noted that ALCL does not typically present with skin ulceration, and this may be a unique disease process in this patient or as a result of her bedridden state given the late stage of her disease. Furthermore, this presentation was uniquely aggressive and presented extremely quickly after placement of the gluteal implants. In most patients, ALCL develops and presents approximately 10 years after implantation.”
The investigators cautioned that “care should be taken to avoid sensationalizing all implant-associated ALCL.”
The authors reported having no conflicts of interest and the study did not receive funding.

Weak evidence surrounds use of mesenchymal stem cells
Weak evidence suggests that prophylactic use of mesenchymal stem cells (MSCs) may reduce the risk of chronic graft-versus-host disease (GVHD) in patients undergoing allogeneic hematopoietic stem cell transplant (HSCT), according to a recent Cochrane review.
However, other uses of MSCs with HSCT – such as prophylaxis with MSCs for acute GVHD or treatment of GVHD – lack evidence of efficacy, reported lead author Sheila A. Fisher, PhD, of National Health Service Blood and Transplant in Oxford (England), and her colleagues.
The investigators noted that most studies included in the review had low-quality evidence.
“[R]andomization methods were poorly reported and several of the included studies were subject to a high risk of performance bias and reporting bias,” the investigators wrote in the Cochrane Database of Systematic Reviews. “One trial which started in 2008 has not been published and the progress of this trial is unknown, leading to potential publication bias. The quality of evidence was therefore low or very low for all outcomes due to a high risk of bias as well as imprecision due to the low number of overall participants, and in some cases, evidence based on a single study.”
The investigators identified 25 randomized, controlled trials (RCTs) involving MSCs for GVHD, of which 12 were completed (879 participants) and 13 were ongoing (1,532 planned participants). Out of the 12 completed trials, 2 compared different doses of MSCs, while 10 compared MSCs with no MSCs. Five trials investigated treatment with MSCs and seven investigated prophylactic use.
The one finding that was supportive of MSCs, albeit based on low-quality evidence, showed that prophylactic use reduced the risk of chronic GVHD, compared with no prophylaxis (risk ratio, 0.66). Other findings were less supportive or unsupportive of MSCs.
Prophylactic use of MSCs had little or no impact on risk of acute GVHD (RR, 0.86; low-quality evidence), risk of relapse of malignant disease (RR, 1.08; low-quality evidence), or all-cause mortality (hazard ratio, 0.85; low-quality evidence).
Treatment with MSCs was disappointing across the board. Risk of all-cause mortality was unaffected (HR, 1.12; very low–quality evidence) and a minimal impact was found for complete responses in acute GVHD (RR, 1.16; very low–quality evidence).
Although treatment of chronic GVHD with MSCs was associated with an improved complete response rate (RR, 5.00), the investigators noted that this finding came from a single trial with 40 participants that was deemed to have very low–quality evidence. The two trials comparing doses of MSCs found no differences between treatment groups.
“Despite a number of reports of positive outcomes from the use of MSCs for treating acute GVHD, the evidence to date from RCTs has not supported the conclusion that they are an effective therapy,” the investigators wrote.
The study was funded by NHS Blood and Transplant. Dr. Fischer reported having no financial disclosures. One coauthor reported research funding from the Leukemia and Lymphoma Research charity and the National Institute for Health Research.
