RESUMO
BACKGROUND: Classic Hodgkin lymphoma (cHL) is a highly-curable disease. However, relapses after bone marrow transplant are challenging especially relapses after allogeneic transplant. METHODS: A retrospective chart review of the institution transplant database to summarize the safety and efficacy of checkpoint inhibitors (CPIs) use for cHL relapses postallo-HCT in patients who already failed to derive sustained benefit from CPIs received prior to allo-HCT. RESULTS: Six cases were identified and reviewed. All patients received and failed to derive sustained benefit from CPIs and brentuximab vedotin preallo-HCT. The median age at the time of allo-HCT was 28.6 years (IQR 23.6-34.2), the median number of lines received prior to allo-HCT was 6.5 (range 5-9). The median duration of CPI therapy prior to allo-HCT was 8.1 months (IQR 6.7-12.9). The median time between the discontinuation of CPI and allo-HCT was 5.78 months (IQR 3.15-15.8). The median time to progression postallo-HCT was 5.75 months (IQR 2.6-11.7). The median time between allo-HCT and re-challenge with a CPI was 7.6 months (IQR 3.2-28.6). The median time of follow up after starting postallo-HCT CPIs was 16 months (IQR 7.25-25.75). Five out six patients responded and two patients developed GvHD. CONCLUSION: Our report shows preserved efficacy without any new safety signals by using CPIs postallo-HCT despite using and having failed to derive sustained benefit from CPIs preallo-HCT.
RESUMO
OBJECTIVE: To compare the all-cause mortality of aged and younger patients undergoing maintenance hemodialysis (MHD) over the long or short term, and to identify independent risk factors. METHODS: We performed a retrospective cohort study using the medical records of 181 patients undergoing MHD. We compared the clinical characteristics and laboratory data of survivors and participants who died, according to their age and the duration of MHD. Binary stepwise logistic regression was used to identify independent risk factors for all-cause mortality. RESULTS: Cardiovascular and cerebrovascular diseases were the principal causes of mortality. The number of aged participants with hypertensive nephropathy as their primary kidney disease was significantly higher than the number of younger participants. The proportion with chronic glomerulonephritis was significantly higher for participants undergoing long-term MHD. Logistic regression analysis revealed that low body mass index, single-pool Kt/V, serum albumin, platelet count, and total iron-binding capacity; and high intact parathyroid hormone and N terminal pro B type natriuretic peptide were independent risk factors for all-cause mortality. CONCLUSIONS: Aged patients are more susceptible to hypertensive nephropathy than younger patients. In addition, the survival of patients with chronic glomerulonephritis undergoing MHD is superior to that of those with hypertensive or diabetic nephropathy.

Pneumocystis pneumonia (PCP) is an opportunistic infection caused by Pneumocystis jirovecii. PCP due to immunosuppressive drugs is rarely reported in the literature. Herein we present a case of PCP in a 49-year-old patient who presented with progressive shortness of breath, dry cough, and low-grade fever. History revealed that he was taking prednisolone daily for his hyperactive airway disease. His temperature was 99oF, and he had bilateral crackles in the lungs with resonant wheezing. High-resolution computed tomography showed diffuse ground-glass haze and cystic lesions in the middle and upper zones of both lungs. He was commenced on intravenous ceftriaxone and methylprednisolone based on provisional diagnosis of interstitial pneumonia. However, his condition worsened. His human immunodeficiency virus (HIV) test was reactive, and his CD4+ count was 275 cells/mm3. Bronchoalveolar lavage revealed PCP by direct immunofluorescent assay. Additional serum testing revealed marked elevation of beta-D-glucan, consistent with PCP diagnosis due to glucocorticoid use. Trimethoprim-sulfamethoxazole and voriconazole were initiated, and his respiratory symptoms started improving. His respiratory condition improved on day 9, and he was discharged with follow-up.
