Pulmonary Artery Pseudoaneurysm in COVID-19-Associated Pulmonary Mucormycosis: Case Series and Systematic Review of the Literature.

ABSTRACT: Literature on COVID-19-associated pulmonary mucormycosis (CAPM) is sparse. Pulmonary artery pseudoaneurysm (PAP) is an uncommon complication of pulmonary mucormycosis (PM), and rarely reported in CAPM. Herein, we report five cases of CAPM with PAP managed at our center and perform a systematic review of the literature. We diagnosed PM in those with clinico-radiological suspicion and confirmed it by microbiology or histopathology. We encountered five cases of CAPM with PAP (size ranged from 1 × 0.8 cm to ~ 4.9 × 4.8 cm). All subjects had diabetes and were aged 55-62 years (75% men). In two cases, COVID-19 and mucormycosis were diagnosed simultaneously, while in three others, COVID-19 preceded PM. One subject who underwent surgery survived, while all others died (80% mortality). From our systematic review, we identified one additional case of CAPM with PAP in a transplant recipient. CAPM with PAP is rare with high mortality. Early diagnosis and multimodality management are imperative to improve outcomes.

Project description:BackgroundCoronavirus disease-2019 (COVID-19) cholangiopathy is a recently known entity. There are very few reports of liver transplantation (LT) for COVID-19-induced cholangiopathy. It is well known that vaccines can prevent severe disease and improve outcomes. However, there are no reports on the impact of COVID-19 vaccines on cholestasis. Therefore, we aimed to compare the course and outcome of patients who developed cholestasis following COVID-19 infection among vaccinated and unvaccinated individuals. Methods: Patients diagnosed with post-COVID cholestasis during the pandemic were included in the study after excluding other causes of cholestasis.ResultsEight unvaccinated and seven vaccinated individuals developed cholestasis following COVID-19 infection. Baseline demographics, presentation, severity, and management of COVID-19 were similar in both groups. However, patients in the unvaccinated group had a protracted course. The peak ALP was 312 (239-517) U/L in the vaccinated group and 571.5 (368-1058) U/L in the unvaccinated group (P = 0.02). Similarly, the peak γ-glutamyl transpeptidase values were lower in the vaccinated (325 [237-600] U/L) than in the unvaccinated group (832 [491-1640] U/L; P = 0.004). However, the peak values of total bilirubin, transaminases, and INR were similar in both groups. Five patients developed ascites gradually in the unvaccinated group whereas none in the vaccinated group developed ascites. Plasma exchange was done in five patients, and two were successfully bridged to living donor LT in the unvaccinated group. Only two patients recovered with conservative management in the unvaccinated group, whereas all recovered with conservative management in the vaccinated group. The other four patients in the unvaccinated group were planned for LT.ConclusionPost-COVID-19 cholestasis is associated with high morbidity and mortality, meriting early identification and appropriate management. Vaccination can modify the course of severe COVID-19 infection and improve outcomes.
