Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a rare occurrence in systemic sclerosis (SSc) patients. AAV is an inflammatory disease that can lead to kidney failure due to the infiltration of mononuclear cells and the destruction of blood vessels. Also, crescentic glomerulonephritis (GN) has rarely been reported with coronavirus disease 2019 (COVID-19) and acute tubular injury is the most common renal pathology lesion in these patients. We present a rare case of a 46-year-old woman with SSc with new onset of renal failure after a recent diagnosis of COVID-19. Her serology was positive for p-ANCA and myeloperoxidase antibodies. Kidney biopsy was done and showed crescentic GN. We suggest during this pandemic, patients with an immunological disorder that are infected with COVID-19 be closely monitored for any organ involvement.

Patient: Female, 59-year-old Final Diagnosis: Posterior reversible encephalopathy syndrome (PRES) Symptoms: Altered mental status Medication:— Clinical Procedure: — Specialty: Cardiology • Critical Care Medicine • General and Internal Medicine • Nephrology • Neurology Objective: Unusual clinical course Background: Posterior reversible encephalopathy syndrome (PRES), also known as reversible posterior leukoencephalopathy, is a neurotoxic state with multiple etiologies characterized by altered mental state, headaches, visual abnormalities, and seizures. This clinico-radiological syndrome is rare, and a high index of suspicion is needed to diagnose, provide adequate treatment, and prevent irreversible neurological sequelae. Case Report: We present a case of a woman with end-stage renal disease (ESRD) who presented with acute confusion and non-convulsive seizures and was later diagnosed with PRES. In this case, altered mental status was initially thought to be secondary to uremic encephalopathy. A diagnosis of PRES was subsequently made after she had several sessions of HD without significant improvement in her mental state, prompting magnetic resonant imaging (MRI) for further evaluation. Specific risk factors for PRES, including blood pressure fluctuations, were targeted and she made significant clinical recovery but had residual functional impairment. Conclusions: This case underscores the need for a high index of suspicion, especially in cases with atypical presentation, as delayed diagnosis can lead to suboptimal outcomes.

Rare coexistence of disease or pathology Background:The management of (Coronavirus disease 2019) COVID-19 pneumonia is ever-evolving. Tocilizumab, a monoclonal antibody against interleukin-6 (IL-6) receptor, have known mortality benefit in severe COVID-19 pneumonia, but data are limited regarding safety. Attributable to the immunomodulatory nature of this medication, patients may be at risk for opportunistic infections, including chronic cavitary pulmonary aspergillosis (CPPA), a slowly progressive disease characterized pulmonary infiltrates and often a newly-formed cavity. However, current guidelines do not emphasize post-treatment surveillance of patients for opportunistic infections, including CPPA. Case Report:We present a particular case of a 64-year-old man treated for COVID-19 pneumonia with Tocilizumab and dexamethasone who developed cavitary pulmonary aspergillosis. He presented to the emergency department with hemoptysis, associated with worsening productive cough, shortness of breath, and weight loss. Computed tomography (CT) of the chest showed areas of focal consolidation and a cavitary lung lesion within the left upper lobe. Sputum culture was positive for Aspergillus niger. The patient received a long course of oral triazole therapy for CPPA, with clinical improvement. CT scan of the chest at 9 months showed that the Itraconazole therapy was effective in resolving the extensive airspace disease and decreasing the size of the upper-lobe cavity and fungal ball. Conclusions:This article illustrates the possibility of a serious infection such as CCPA as an adverse effect of Tocilizumab treatment, especially with concurrent immunosuppressive therapy. Furthermore, this case highlights the importance of regular monitoring of patients who have received Tocilizumab therapy to ensure that early signs of opportunistic infections such as CPPA are detected and treated promptly to prevent permanent lung damage.
