IMPORTANCE COVID-19 is a life-threatening illness for many patients. Prior studies have established hematologic cancers as a risk factor associated with particularly poor outcomes from COVID-19. To our knowledge, no studies have established a beneficial role for anti-COVID-19 interventions in this at-risk population. Convalescent plasma therapy may benefit immunocompromised individuals with COVID-19, including those with hematologic cancers.OBJECTIVE To evaluate the association of convalescent plasma treatment with 30-day mortality in hospitalized adults with hematologic cancers and COVID-19 from a multi-institutional cohort. DESIGN, SETTING, AND PARTICIPANTSThis retrospective cohort study using data from the COVID-19 and Cancer Consortium registry with propensity score matching evaluated patients with hematologic cancers who were hospitalized for COVID-19. Data were collected between
The risk of disease progression was higher among patients with MDS in whom persistent disease-associated mutations were detected in the bone marrow 30 days after transplantation than among those in whom these mutations were not detected. (Funded by the Leukemia and Lymphoma Society and others.).
Mycophenolate mofetil (MMf) has recently been reported as a useful alternative immunosuppressive drug in autoimmune diseases. There is paucity of literature on its use in Takayasu's arteritis (TA). The aim of this study was to assess the safety and efficacy of MMf in Asian Indian patients with Takayasu's arteritis. Records of 21 consecutive patients with TA on treatment with oral MMF attending our centre from January 2005 to August 2008 were studied. The clinical, laboratory and angiography findings were noted and disease activity assessment was done using Indian Takayasu's arteritis activity score (ITAS) and physician's global observation score at baseline and last follow-up. Eleven patients were on steroids alone at baseline while ten patients had received azathioprine prior to administration of mycophenolate. The mean duration of follow-up on mycophenolate was 9.6 (+/-6.4) months. Nineteen patients (90%) received mycophenolate due to active disease, while in the other two patients, it was given to facilitate steroid tapering. Mycophenolate had to be discontinued in one patient due to skin rash. At the last visit, all the remaining 20 patients who continued mycophenolate had improvement in disease activity as evident by the drop in median ITAS [7 (range 0-19) versus 1 (range 0-7); p=0.001]. A similar trend was noted in laboratory markers of inflammation with a reduction in mean Erythrocyte Sedimentation Rate (ESR) (68+/-36.5 versus 43.2+/-34 mm/first hour; p=0.003) and mean C - Reactive protein (CRP) (31+/-46.7 versus 17.3+/-23.9 mg/L; p=1.00). All patients received concomitant steroids, but there was a significant decrease in steroid dosage from 36 (+/-16) mg/day at baseline to 19 (+/-14) mg/day at last follow-up (p<0.001). This study is the largest series till date establishing the use of mycophenolate as a safe and effective steroid-sparing immunosuppressant in Takayasu's arteritis.
Background Venous thromboembolism (VTE) is a complication of glioblastoma. Anticoagulating patients with glioblastoma carries a theoretical risk of intracranial hemorrhage (ICH). Methods We performed a retrospective cohort study of consecutive glioblastoma patients (2007–2013) diagnosed with VTE. Results The study population comprised of 523 glioblastoma patients of whom 173 (33%) had VTE events. Seventeen (10%) had ICH: 6 (35%) subdural hematomas and 11 (65%) intratumoral hemorrhages. In total, 4 patients with ICH required neurosurgical intervention. Enhancement in the area of subsequent intratumoral hemorrhage was noted in 9 of 10 with available pre-ICH scans. Multivariable regression did not show associations between ICH and tumor enhancement diameter or use of vascular-endothelial-growth-factor inhibitor. Fifteen (16%) patients receiving anticoagulation had ICH compared with 2 (2.6%) not receiving anticoagulation (P = .005). The method of anticoagulation was not associated with development of ICH. Median survival times from nondistal VTE diagnosis to death were 8.0 and 3.5 months (P = .05) in patients receiving anticoagulation and those not on anticoagulation, respectively. Conclusion Patients with glioblastoma and VTE on anticoagulation have increased incidence of ICH. However, development of ICH was not associated with lower median survival from time of VTE. Intratumoral hemorrhage occurred within the enhancing portion of tumor; however, no relationship was identified between the development of ICH and (i) the median diameter of enhancement or (ii) type of anticoagulant used. However, patients with absence of enhancing tumor did not have intratumoral bleed, suggesting gross total resection may limit this adverse outcome. It is appropriate to initiate anticoagulation in glioblastoma patients with VTEs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
