ABSTRACT
BRASH syndrome, characterized by bradycardia, renal failure, atrioventricular (AV) blockage, shock, and hyperkalemia, is an emerging clinical entity that challenges healthcare practitioners. This case report presents a unique instance of BRASH syndrome with an atypical presentation in a 56-year-old woman with a past medical history of hypertension, diabetes, and chronic kidney disease. Initial laboratory results revealed severe normocytic anemia, thrombocytopenia, renal dysfunction, acidosis, and hyponatremia, alongside hyperkalemia and hypothyroidism. An electrocardiogram depicted sinus arrest with atrial escape rhythms, indicative of severe bradycardia. Imaging studies revealed pleural effusion and ground glass opacities. Management involved anti-hyperkalemic measures, discontinuation of AV nodal-blocking agents, thyroid hormone replacement, and vasopressor support. The patient eventually improved following continuous renal replacement therapy (CRRT) and hemodialysis. The diagnosis of BRASH syndrome emerged as the most likely due to recurrent admissions with similar clinical features. BRASH syndrome represents a complex interplay between AV nodal block and hyperkalemia, leading to severe bradycardia and shock, often affecting older patients with limited renal reserve. While the current literature primarily consists of case reports, raising awareness of BRASH syndrome is crucial for timely intervention and improved patient outcomes. Further research is needed to better understand the mechanisms underlying this syndrome.
ABSTRACT
Sarcina ventriculi is an anaerobic gram-positive coccus that can resist the acidic media of the stomach and cause gastrointestinal symptoms. Here, we report the case of a 43-year-old male patient with a history of schizophrenia presenting with abdominal distention, nausea, vomiting, early satiety, and weight loss. Computed tomography of the abdomen and pelvis with contrast revealed a severely dilated stomach and signs of gastric outlet obstruction on multiple occasions. The endoscopic evaluation showed a dilated stomach, and biopsies revealed non-specific gastritis, negative Helicobacter pylori, and positive S. ventriculi with metaplasia. Medical treatment with proton pump inhibitors, pro-kinetics, ciprofloxacin, and metronidazole failed to improve his symptoms. Finally, the patient was managed surgically with distal gastrectomy with Roux en Y reconstruction, and gastrostomy tube placement was done with satisfactory improvement in his symptoms.
ABSTRACT
INTRODUCTION: The pathophysiology for Coronavirus Disease 2019 (COVID-19) infection is characterized by cytokine oxidative stress and endothelial dysfunction. Intravenous (IV) vitamin C has been utilized as adjuvant therapy in critically ill patients with sepsis for its protective effects against reactive oxygen species and immunomodulatory effects. The primary objective of this study was to evaluate the effects of IV vitamin C in critically ill patients with COVID-19 infection. METHODS: Retrospective observational cohort study with propensity score matching of intensive care unit (ICU) patients who received 1.5 grams IV vitamin C every 6 hours for up to 4 days for COVID-19 infection. The primary study outcome was in-hospital mortality. Secondary outcomes included vasopressor requirements in norepinephrine equivalents, ICU length of stay, and change in Sequential Organ Failure Assessment (SOFA) score. RESULTS: Eight patients received IV vitamin C and were matched to 24 patients. Patients in the IV vitamin C group had higher rates of hospital mortality [7 (88%) vs. 19 (79%), P = 0.049]. There was no difference in the daily vasopressor requirement in the treatment group or between the 2 groups. The mean SOFA scores post-treatment was higher in the IV vitamin C group (12.4 ± 2.8 vs. 8.1 ± 3.5, P < 0.005). There was no difference in ICU length of stay between the treatment and control groups. CONCLUSION: Adjunctive IV vitamin C for the management of COVID-19 infection in critically ill patients may not decrease the incidence of mortality, vasopressor requirements, SOFA scores, or ventilator settings.

INTRODUCTION: The Coronavirus Disease 2019 (COVID-19) is associated with severe hypercoagulability. There is currently limited evidence supporting the routine use of therapeutic anticoagulation in the setting of COVID-19. OBJECTIVES: The primary objective was to compare the incidence of thromboembolic events in adult patients with COVID-19 treated with an unfractionated heparin (UFH) infusion versus prophylactic dose anticoagulation. Secondary objectives included exploration of the efficacy and safety of an UFH infusion through the evaluation of organ function and incidence of minor and major bleeding. METHODS: Retrospective observational cohort study with propensity score matching of COVID-19 patients who received an UFH infusion targeting an aPTT between 40 and 60 seconds. RESULTS: Fifty-six patients were included in this study. There was no difference in the composite of thromboembolic events comprised of venous thromboembolism, arterial thrombosis, and catheter-related thrombosis between the UFH and control group (17.9% vs. 3.6%, P = 0.19). There was a significant increase in median D-dimer concentrations from day 1 to day 7 in the control group (475 ng/mL [291-999] vs. 10820 ng/mL [606-21033], P = 0.04). Patients treated with UFH had a higher incidence of minor bleeding (35.7% vs. 0%, P < 0.005) and required more units of packed red blood cell transfusion (0.8 units ± 1.6 vs. 0 units, P = 0.01). CONCLUSION: Continuous infusion of UFH for patients with COVID-19 infection did not decrease the overall incidence of thromboembolic complications. UFH was associated with stabilization of D-dimer concentrations and increased rates of minor bleeding and transfusions.
