Case of Suspected SARS-CoV-2 Vaccine-induced Immune Thrombotic Thrombocytopenia: Dilemma for Organ Donation.

Several vaccines were developed and rolled out at an unprecedented rate in response to the coronavirus disease-2019 (COVID-19) pandemic. Most vaccines approved globally by WHO for emergency use to combat the pandemic were deemed remarkably effective and safe. Despite the safety, rare incidences of vaccine-induced thrombosis and thrombocytopenia (VITT), sometimes known as vaccine-induced prothrombotic thrombocytopenia (VIPIT), have been reported. We report a case of young female with prothrombotic conditions and suspected VITT who developed catastrophic cerebral venous sinus thrombosis (CVST) and progressed to brain death. We highlight hurdles of organ retrieval from a brain-dead patient with suspected SARS-CoV-2 vaccine-induced immune thrombotic thrombocytopenia. There is limited data and lack of substantial evidence regarding transplantation of organs from brain-dead patients with suspected VITT.

Timing of Invasive Mechanical Ventilation and Mortality among Patients with Severe COVID-19-associated Acute Respiratory Distress Syndrome.

BACKGROUND: Severe acute respiratory distress syndrome associated with coronavirus disease-2019 (COVID-19) (CARDS) pneumonitis presents a clinical challenge as regards to the timing of intubation and ambiguity of outcome. There is a lack of clear consensus on when to switch patients from trials of noninvasive therapies to invasive mechanical ventilation. We investigated the effect of the timing of intubation from the time of admission on the clinical outcome of CARDS. AIM AND OBJECTIVE: The aim and objective was to analyze the effect of timing of intubation early (within 48 hours of admission to critical care unit) versus delayed (after 48 hours of admission to critical care unit) on mortality in severe CARDS patients. MATERIALS AND METHODS: A retrospective observational study performed in a 28-bedded COVID-19 intensive care unit of a tertiary care hospital in Pune, India. All patients admitted between April 1, 2020, and October 15, 2020, with confirmed COVID-19 (RT-PCR positive) requiring mechanical ventilation were included in the study. RESULTS: The primary outcome was in-hospital mortality. Among 2,230 patients that were admitted to the hospital, 525 required critical care (23.5%), invasive mechanical ventilation was needed in 162 patients and 147 (28%) of critical care admission were included in the study cohort after exclusion. Seventy-five patients (51%) were intubated within 48 hours of critical care admission (early group) and 72 (48.9%) were intubated after 48 hours of critical care admission (delayed group). With regards to the total of 147 included patients; male patients were 74.1% with a median age of 59 years (interquartile range, 51-68 years). Diabetes (44.9%) and hypertension (43.5%) were the most common comorbidities. Higher admission acute physiology and chronic health evaluation II scores and lower absolute lymphocyte count were observed in patients intubated within 48 hours. The early intubated group had a mortality of 60% whereas the same was observed as 77.7% in delayed intubation group, and this difference was statistically significant (p = 0.02). CONCLUSION: Current study concludes that early intubation is associated with improved survival rates in severe CARDS patients.

A Retrospective Analysis of Risk Factors of COVID-19 Associated Mucormycosis and Mortality Predictors: A Single-Center Study.

Background Mucormycosis has been identified with increasing frequency in patients with coronavirus disease 2019 (COVID-19). Aims We aimed to determine the in-hospital outcome of patients with COVID-19 associated mucormycosis (CAM). Materials and methods This was a single-center, retrospective, observational study. We included patients diagnosed with CAM from a tertiary care hospital in Pune, India. Clinical, laboratory, and in-hospital outcomes were noted. We analyzed factors associated with in-hospital mortality. Results Between February 2021 and June 2021, we identified 84 patients of CAM. The mean age was 49.3 ± 12.1 years. Of the included patients, 64.3% had diabetes mellitus, and 83.3% had received steroids. Mucormycosis was diagnosed after a median of 11 days from the COVID-19 diagnosis. Orbital and central nervous system (CNS) involvement was seen in 29.8% and 23.8% of patients, respectively. During a mean hospital stay of 12.5 ± 8.5 days, 15.5% of patients died. Compared to survivors, the presence of chronic kidney disease (CKD) (p<0.0001), orbital involvement (p=0.039), use of tocilizumab (p<0.0001), and development of renal dysfunction during hospitalization (p<0.0001) were seen in a significantly higher proportion of nonsurvivors. The proportion of patients with diabetes, those receiving steroids, and mean glycosylated hemoglobin (HbA1c) levels did not differ significantly in survivors and nonsurvivors. Conclusion In-hospital mortality in CAM is relatively lower in our institution. CKD, orbital involvement, use of tocilizumab, and renal dysfunction during hospital stay were found to be strong predictors of mortality.
