Background:The ideal treatment of coronavirus disease (COVID)-19 has yet to be defined, but convalescent plasma (Co-Pla) has been successfully employed. Objective: The objective of the study was to study the safety and outcomes of the administration of CoPla to individuals with severe COVID-19 in an academic medical center. Methods: Ten patients were prospectively treated with plasma from COVID-19 convalescent donors. Results: Over 8 days, the sequential organ failure assessment score dropped significantly in all patients, from 3 to 1.5 (p = 0.014); the Kirby index (PaO 2 /FiO 2 ) score increased from 124 to 255, (p < 0.0001), body temperature decreased significantly from 38.1 to 36.9°C (p = 0.0058), and ferritin levels also dropped significantly from 1736.6 to 1061.8 ng/ml (p = 0.0001). Chest X-rays improved in 7/10 cases and in 6/10, computerized tomography scans also revealed improvement of the lung injury. Decreases in C-reactive protein and D-dimer levels were also observed. Three of five patients on mechanical ventilation support could be extubated, nine were transferred to conventional hospital floors, and six were sent home; two patients died. The administration of CoPla had no side effects and the 24-day overall survival was 77%. Conclusions: Although other treatments were also administered to the patients and as a result data are difficult to interpret, it seems that the addition of CoPla improved pulmonary function.

Objective:Sticky platelet syndrome (SPS) is an inherited condition that leads to arterial and venous thrombosis. There is scant information about the association between SPS and obstetric complications. This study aimed to assess the relationship between SPS and fetal loss at a single institution.Materials and Methods:The obstetric histories of all consecutive female patients prospectively studied in a 324-month period at a single institution with a history of thrombosis and a clinical marker of primary thrombophilia were reviewed.Results:Between 1989 and 2016, 268 consecutive patients with a clinical marker of primary thrombophilia and a history of arterial or venous thrombosis were studied; of these, 108 were female patients. Within this subset of thrombophilic females, 77 (71%) had been pregnant at some point. Twenty-eight of these 77 patients (37%) had had a spontaneous abortion and 24 of those (86%) were found to have SPS. On the other hand, in a subset of 73 female patients with SPS who had been pregnant, 32% had miscarriages. These figures are significantly higher than the prevalence of spontaneous abortions in the general Mexican population of pregnant women, which is 12%-13% (chi-square: 7.47; p=0.0063). Accordingly, the relative risk of having a miscarriage is 2.66 times higher in female patients with SPS than in the general population (p=0.0014).Conclusion:In Mexico, female patients with SPS experience significantly more spontaneous abortions than the general population. Since the treatment of SPS is simple and effective and could in turn prevent adverse obstetric outcomes, its investigation in women treated for obstetric complications may be useful and deserves further research.
Background: Persons with multiple sclerosis are increasingly treated with intermediate-or high-dose chemotherapy and a hematopoietic cell autotransplant. This is often done in an inpatient setting using frozen blood cell grafts.Objective: Determine if chemotherapy and a hematopoietic cell autotransplant can be safely done in an outpatient setting using refrigerated, non-frozen grafts. Methods:We developed an autotransplant protocol actionable in an outpatient setting using a refrigerated, non-frozen blood graft collected after giving cyclophosphamide, 50 mg/kg/d × 2 days and filgrastim, 10 μg/kg/d. A second identical course was given 9 days later followed by infusion of blood cells stored at 4°C for 1-4 days. The co-primary outcomes were rates of granulocyte and platelet recovery and therapyrelated mortality. Results:We treated 426 consecutive subjects. Median age was 47 years (range, 21-68 years). A total of 145 (34%) were male. Median graft refrigeration time was 1 day (range, 1-4 days). Median interval to granulocytes >0.5 × 10E + 9/L was 8 days (range, 2-12) and to platelets >20 × 10E + 9/L, 8 days (range, 1-12). Only 15 subjects (4%) were hospitalized, predominately for iatrogenic pneumothorax (N = 5) and neutropenic fever (N = 4). There was only 1 early death from infection. Conclusion:Intermediate-dose chemotherapy and a hematopoietic cell autotransplant can be safely done in an outpatient setting using, refrigerated, non-frozen grafts.
NAFLD should be considered as a cause of mild thrombocytopenia. Our initial observation has been confirmed and defined more precisely. Additional studies are needed to further define more features of the thrombocytopenia of NAFLD, as well as its mechanisms.
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.
