Background African-Americans/Blacks have suffered higher morbidity and mortality from COVID-19 than all other racial groups. This study aims to identify the causes of this health disparity, determine prognostic indicators, and assess efficacy of treatment interventions. Methods We performed a retrospective cohort study of clinical features and laboratory data of COVID-19 patients admitted over a 52-day period at the height of the pandemic in the United States. This study was performed at an urban academic medical center in New York City, declared a COVID-only facility, serving a majority Black population. Results Of the 1103 consecutive patients who tested positive for COVID-19, 529 required hospitalization and were included in the study. 88% of patients were Black; and a majority (52%) were 61–80 years old with a mean body mass index in the “obese” range. 98% had one or more comorbidities. Hypertension was the most common (79%) pre-existing condition followed by diabetes mellitus (56%) and chronic kidney disease (17%). Patients with chronic kidney disease who received hemodialysis were found to have lower mortality, than those who did not receive it, suggesting benefit from hemodialysis Age > 60 years and coronary artery disease were independent predictors of mortality in multivariate analysis. Cox proportional hazards modeling for time to death demonstrated a significantly high ratio for COPD/Asthma, and favorable effects on outcomes for pre-admission ACE inhibitors and ARBs. CRP (180, 283 mg/L), LDH (551, 638 U/L), glucose (182, 163 mg/dL), procalcitonin (1.03, 1.68 ng/mL), and neutrophil:lymphocyte ratio (8.3:10.0) were predictive of mortality on admission and at 48–96 h. Of the 529 inpatients 48% died, and one third of them died within the first 3 days of admission. 159/529patients received invasive mechanical ventilation, of which 86% died and of the remaining 370 patients, 30% died. Conclusions COVID-19 patients in our predominantly Black neighborhood had higher in-hospital mortality, likely due to higher prevalence of comorbidities. Early dialysis and pre-admission intake of ACE inhibitors/ARBs improved patient outcomes. Early escalation of care based on comorbidities and key laboratory indicators is critical for improving outcomes in African-American patients.

Early in the SARS-CoV-2 pandemic, convalescent plasma (CP) therapy was proposed as a treatment for severely ill patients. We conducted a CP treatment protocol under the Mayo Clinic Extended Access Program at University Hospital Brooklyn (UHB). Potential donors were screened with a lateral flow assay (LFA) for IgM and IgG antibodies against the SARS-CoV-2 S1 receptor-binding domain (RBD). Volunteers that were LFA positive were tested with an ELISA to measure IgG titers against the RBD. Subjects with titers of at least 1:1024 were selected to donate. Most donors with positive LFA had acceptable titers and were eligible to donate. Out of 171 volunteers, only 65 tested positive in the LFA (38.0%), and 55 (32.2%) had titers of at least 1:1024. Before our donation program started, 31 CP units were procured from the New York Blood Center (NYBC). Among the 31 CP units that were obtained from the NYBC, 25 units (80.6%) were positive in the LFA but only 12 units (38.7%) had titers of at least 1:1024. CP was administered to 28 hospitalized COVID-19 patients. Patients who received low titer CP, high titer CP and patients who did not receive CP were followed for 45 days after presentation. Severe adverse events were not associated with CP transfusion. Death was a less frequent outcome for patients that received high titer CP (>1:1024) 38.6% mortality, than patients that received low titer CP (≤1:1024) 77.8% mortality.

BACKGROUND Central nervous system (CNS) tuberculomas are a feared complication of tuberculosis (TB) infection. These lesions can present in varying manners and are associated with significant morbidity and mortality. Prompt diagnosis and treatment of the lesion and the underlying infection are critical in the care of these patients. The authors presented a case of a 45-year-old Yemeni immigrant presenting with a 3-month history of severe right temporo-occipital headaches with photophobia and night sweats. Imaging showed a rim-enhancing lesion in the right cerebellar hemisphere. OBSERVATIONS Laboratory tests were unremarkable and within normal limits. QuantiFERON testing was negative, ruling out latent TB infection. The patient received a suboccipital craniotomy, and resection of the cerebellar lesion showed caseating granuloma formation, which was positive for acid-fast bacilli and Fite stain. LESSONS CNS tuberculomas are an important differential to consider in patients with a history of primary TB, regardless of active disease or immunocompetent status. Resection of these lesions remains a viable treatment option that is safe and effective.

Background African-Americans/Blacks have suffered higher morbidity and mortality from COVID-19 than all other racial groups. This study aims to identify the causes of this health disparity, determine prognostic indicators, and assess efficacy of treatment interventions. Method We performed a retrospective cohort study of clinical features and laboratory data of COVID-19 patients admitted over a five-week period at the height of the pandemic in the United States. This study was performed at an urban academic medical center in New York City, declared a COVID-only facility, serving a majority Black population Result Of the 1,070 consecutive patients who tested positive for COVID-19, 496 critically ill patients were hospitalized and included in the study. 88% of patients were Black; and a majority (53%) were 61-80 years old with a mean body mass index in the 'obese' range. 97% had one or more comorbidities. Hypertension was the most common (84%) pre-existing condition followed by diabetes mellitus (57%) and chronic kidney disease (24%). Patients with chronic kidney disease and end-stage renal disease who received hemodialysis were found to have significantly lower mortality, then those who did not receive it, suggesting benefit from hemodialysis (11%, OR, 0.35, CI, 0.17 - 0.69 P=0.001). Age >60 years and coronary artery disease were independent predictors of mortality in multivariate analysis. Cox Proportional Hazards modeling for time to death demonstrated a significantly high ratio for COPD/Asthma, and favorable effects on outcomes for pre-admission ACE inhibitors and ARBs. CRP (180, 283 mg/L), LDH (551, 638 U/L), glucose (182, 163 mg/dL), procalcitonin (1.03, 1.68 ng/mL), and neutrophil / lymphocyte ratio (8.5, 10.0) were predictive of mortality on admission and at 48-96 hrs. Of the 496 inpatients, 48% died, one third of patients died within the first three days of admission. 54/488 patients received invasive mechanical ventilation, of which 87% died and of the remaining patients, 32% died. CONCLUSIONS COVID-19 patients in our predominantly Black neighborhood had higher mortality, likely due to higher prevalence of comorbidities. Early dialysis and pre-admission intake of ACE inhibitors/ARBs improved patient outcomes. Early escalation of care based on comorbidities and key laboratory indicators is critical for improving outcomes in African-American patients.

Introduction/Objective Recent reports suggest that though COVID-19 is predominantly a respiratory pathogen, one of its presenting features can be gastrointestinal symptoms. We hereby present a case of a female with COVID-19 infection whose hospital course was complicated by colonic pseudo-obstruction caused by pseudomembranous colitis resulting in an emergent hemicolectomy. Methods A 59-Year-old female with history of hypertension, diabetes, and breast cancer post mastectomy presented with pneumonia and was confirmed to be COVID-19 positive. She was admitted to the hospital and was treated with Azithromycin for 6 days. Patient developed constipation on day six of hospitalization and started having abdominal pain on day eight with elevated WBC count. Imaging showed distension of cecum and proximal colon. She underwent exploratory laparotomy which revealed a necrotic appearing cecum that was massively dilated and had a serosal tear. These findings prompted emergent hemicolectomy with loop ileostomy. Grossly cecum was black/green, dilated, thin walled with a 5 x 5 cm yellow green raised plaques. Microscopy of the plaques revealed focal erosion of colonic mucosa with overlying acute inflammatory cells, fibrin deposits, mucus, and necrotic epithelial cells consistent with pseudomembranous colitis. Conclusion Review of literature shows no reported cases of intestinal pseudo-obstruction due to pseudomembranous colitis in a COVID-19 patient. Not only this, but there are also only a limited number of case studies of pseudomembranous colitis presenting as intestinal pseudo-obstruction without diarrhea. Though this patient’s presentation could be from Clostridium difficile infection secondary to Azithromycin, it is not a common antibiotic to cause this. Also, one of the known causes of pseudomembranous colitis is ischemia. Given that COVID-19 infection is a pro-thrombotic condition, possible ischemia secondary to COVID-19 infection related coagulopathy should also be a consideration.
