Diffuse alveolar hemorrhage (DAH) is a rare syndrome resulting from the accumulation of intra-alveolar red blood cells originating most often from the alveolar capillaries and, less frequently, from precapillary arterioles or postcapillary venules. The causes of DAH can be divided into infectious and noninfectious. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus that has not been previously identified in humans, and it is responsible for coronavirus disease-19 (COVID-19) infection.Here, we present a case of DAH that is believed to be a consequence of COVID-19 infection in a female patient with no known past medical history. The patient was found to be positive for perinuclear antineutrophil cytoplasmic antibodies (P-ANCA) and anti-glomerular basement membrane antibodies. The patient was diagnosed with ANCA-associated vasculitis with glomerulonephritis and was treated successfully with methylprednisolone 500 mg intravenous (IV) daily for three days, followed by rituximab 375 mg/m 2 IV once weekly for four weeks. The long-term complications of COVID-19 are not entirely known and are still being investigated. The association between COVID-19 infection and DAH is not fully known. However, the inflammatory process of COVID-19 infection may have a role in vasculitis, leading to DAH.

One of the most effective strategies in reducing the risk of Clostridium difficile infection (CDI) recurrence is fecal microbiota transplantation (FMT). However, several adverse events have been reported post FMT, and data on the efficacy and safety of FMT in immunocompromised patients with hematological malignancies are rare. is report presents FMT treatment for refractory CDI in a severely immunocompromised patient. A 69-year-old female presented to the emergency department complaining of foul smelling, intractable, watery diarrhea and generalized abdominal pain. She was recently diagnosed with high-risk myelodysplastic Syndrome (MDS) requiring daily blood transfusions and reported multiple CDI episodes in the past treated successfully with metronidazole and vancomycin as mono-or combotherapy. During this admission, treatment with oral vancomycin (high dose) and intravenous metronidazole was unsuccessful, so FMT was administered. e patient recovered well despite an absolute neutrophil count (ANC) < 0.25 × 10 9 /L, and chemotherapy was initiated soon after. FMT was successful and safe in this patient, with no relapse and adverse events seen in 8 weeks of follow-up via phone calls and office visits.

Patient: Male, 81 Final Diagnosis: IgA nephropathy flare up Symptoms: Fever Medication: — Clinical Procedure: — Specialty: Infectious Diseases Objective: Rare disease Background: Glomerulonephritis (GN) associated with post staphylococcus infection (PSIGN) and high serum immunoglobulin A (IgA) has been reported recently. Patients with GN after infection with underlying IgA nephropathy create a challenge to determine the etiology of GN. Therefore, treatment should be accordingly, with steroids used if the IgA nephropathy flare-up is determined to be the etiology. The aim of this case report was to shed light on the difference between PSIGN and IgA nephropathy flare-ups in patients with a history of IgA nephropathy, and how to treat patient cases accordingly. Case Report: An 81-year-old male presented to our Emergency Department complaining of increasing pain, swelling, and redness of his left knee since 2 days ago. He had a history of recent methicillin sensitive Staphylococcus aureus (MSSA) left knee arthroplasty infection that was treated with cefazolin, and he had a history of IgA nephropathy diagnosed 1 year ago. Conclusions: In our patient case, renal biopsy studies were not enough to differentiate between PSIGN and IgA nephropathy flare-ups, thus, clinical presentation was important. PSIGN was found to have a delayed onset compared to IgA nephropathy. Lower serum complement 3 (C3) level, heavier proteinuria, and acute renal failure are common with PSIGN compared to IgA nephropathy. Identifying the etiology and treating our patient accordingly with immunosuppressive therapy had a positive impact on the patient, restoring renal function without further damage.
