COVID-19 patients' clinical profile and outcome with respect to their vaccination status: A prospective observational multicentre cohort study during third wave in Western India.

PURPOSE: To understand the benefits of COVID-19 vaccination (Covishield, Covaxin) on clinical features and outcome of COVID-19 during the third wave in India. MATERIALS AND METHODS: The primary study aim was to describe the clinical profile and outcome of COVID-19 regarding their vaccination and to identify risk factors for disease progression in vaccinated patients. This was a prospective observational multicentric study of COVID-19 attended by Infectious Disease physicians during January 15, 2022 to February 15, 2022. Adult patients with positive RT-PCR or rapid antigen test for COVID-19 were enrolled. Patient received treatment as per local institutional protocol. Chi square test for categorical and Mann Whitney test for continuous variables were applied for the analysis. Logistic regression was used to calculate adjusted odds ratios. RESULTS: A total of 788 patients were included in analysis out of 883 enrolled patients from 13 centers across Gujarat. By the end of two weeks' follow up, 22 patients (2.8%) had expired. The Median age of subjects was 54 years, with a (55.8%) male. 90% of the subjects were vaccinated, majority (77%) of them had received 2 doses of vaccine with Covishield (659, 93%). Mortality among the non-vaccinated was significantly (11.4%) higher than vaccinated (1.8%). Logistic regression analysis showed numbers of comorbidities (p â€‹= â€‹0.027), baseline higher WBC count (p â€‹= â€‹0.02), higher NLR (p â€‹= â€‹0.016), and Ct value (p â€‹= â€‹0.046) were associated with mortality while vaccination was associated with survival (p â€‹= â€‹0.001). The factors associated with mortality among vaccinated were age, comorbidities, baseline higher WBC, NLR, and CRP. CONCLUSIONS: Omicron variant was associated with mild symptoms. Clinical and laboratory risk factors for getting severe disease with Omicron variant were the same with previous SARS CoV-2 strain. Two doses of vaccine protect people against severe disease and death. Age, comorbidities, baseline leucocytosis, high NLR, elevated CRP are the risk factors for poor outcome in vaccinated patients.

Risk factors for COVID-19 associated mucormycosis in India: A case control study.

The coronavirus disease 2019 (COVID-19) pandemic had led to an increase in a surge of mucormycosis in COVID-19 patients, especially in India. Diabetes and irrational usage of corticosteroids to treat COVID-19 were some of the factors implicated for COVID-19-associated mucormycosis (CAM). We designed this case-control study to identify risk factors for mucormycosis in COVID-19 patients. The study was conducted at a private tertiary care center in western India. Data were extracted from records of COVID 19 patients (January-May 2021) and divided into two groups: Those with proven or probable mucormycosis, and those without mucormycosis with a ratio of 1:3. A binary logistic regression analysis was done to assess potential risk factors for CAM. A total of 64 CAM and 205 controls were included in the analysis. Age and sex distribution were similar in cases and controls with the majority of males in both the groups (69.9%) and the mean age was 56.4 (±13.5) years. We compared the comorbidities and treatment received during acute COVID-19, specifically the place of admission, pharmacotherapy (steroids, tocilizumab, remdesivir), and the requirement of oxygen as a risk factor for CAM. In a multivariate analysis, risk factors associated with increased odds of CAM were new-onset diabetes (vs. non-diabetics, adjusted odds ratio [OR] 48.66, 95% confidence interval [CI] 14.3-166), pre-existing diabetes (vs. non-diabetics, aOR 2.93, 95%CI 1.4-6.1), corticosteroid therapy (aOR 3.64, 95%CI 1.2-10.9) and home isolation (vs. ward admission, aOR 4.8, 95%CI 2-11.3). Diabetes, especially new-onset, along with corticosteroid usage and home isolation were the predominant risk factors for CAM. LAY SUMMARY: This study revealed new-onset diabetes, pre-existing diabetes, corticosteroid therapy, and home isolation as risk factors for COVID-19-associated mucormycosis. Avoiding the use of corticosteroids in non-severe COVID-19 disease coupled with proper blood sugar monitoring and control will help to reduce the CAM burden.

Definition, diagnosis, and management of COVID-19-associated pulmonary mucormycosis: Delphi consensus statement from the Fungal Infection Study Forum and Academy of Pulmonary Sciences, India.

COVID-19-associated pulmonary mucormycosis (CAPM) remains an underdiagnosed entity. Using a modified Delphi method, we have formulated a consensus statement for the diagnosis and management of CAPM. We selected 26 experts from various disciplines who are involved in managing CAPM. Three rounds of the Delphi process were held to reach consensus (≥70% agreement or disagreement) or dissensus. A consensus was achieved for 84 of the 89 statements. Pulmonary mucormycosis occurring within 3 months of COVID-19 diagnosis was labelled CAPM and classified further as proven, probable, and possible. We recommend flexible bronchoscopy to enable early diagnosis. The experts proposed definitions to categorise dual infections with aspergillosis and mucormycosis in patients with COVID-19. We recommend liposomal amphotericin B (5 mg/kg per day) and early surgery as central to the management of mucormycosis in patients with COVID-19. We recommend response assessment at 4-6 weeks using clinical and imaging parameters. Posaconazole or isavuconazole was recommended as maintenance therapy following initial response, but no consensus was reached for the duration of treatment. In patients with stable or progressive disease, the experts recommended salvage therapy with posaconazole or isavuconazole. CAPM is a rare but under-reported complication of COVID-19. Although we have proposed recommendations for defining, diagnosing, and managing CAPM, more extensive research is required.

Therapeutic drug monitoring of posaconazole delayed release tablet while managing COVID-19-associated mucormycosis in a real-life setting.

BACKGROUND: Along with COVID-19 pandemic, India has faced an outbreak of COVID-19-associated mucormycosis (CAM). Due to restricted availability of amphotericin B during this outbreak, clinicians were forced to use posaconazole or isavuconazole preparations as first-line or alternate therapy in many patients. We planned an early monitoring of posaconazole trough level while using delayed release (DR) tablet as first-line or alternate therapy. OBJECTIVES: Primary objective of the study was to determine percentage of patients achieving arbitrarily decided therapeutic posaconazole levels (≥1.2 µg/ml) after using standard dosages of posaconazole. Secondary objective was to identify potential factors associated with sub-therapeutic posaconazole levels. METHODS: We performed retrospective chart review of the hospitalised patients, who received posaconazole DR tablet as first-line or alternate therapy to treat CAM during outbreak period (March 1 to May 31, 2021). High-performance liquid chromatographic (HPLC) method was used to measure trough level of posaconazole. RESULTS: Posaconazole serum levels of 29 patients were analysed, who received posaconazole DR tablet. Majority (n = 23) were male with the median (range) age 53 (24-86) years. The mean (SD) posaconazole level was 1.66 (0.76) µg/ml. Sub-therapeutic posaconazole trough level was observed in 7 (24.1%) patients. Relatively younger patients were associated with lower posaconazole level (p = .046). Except two patients, all the patients tolerated posaconazole well. CONCLUSIONS: The study supports the posaconazole trough level measurement on day 4 while using posaconazole DR tablet as first-line or alternate therapy to treat mucormycosis during limited supply of amphotericin B.

Protecting health-care professionals and workers (other than COVID-19 management facilities) from contamination during COVID-19 pandemic (March 26, 2020 - India)

People should stay at home - just as our PM has appealed on TV to the nation. This saves people plus health-care professionals from getting infected. Patients with ongoing illnesses should continue with usual treatment, cancel routine medical appointments (doctor visits and investigations), and contact their respective doctors (through email or digital platforms) only in case of new significant problems. Hospitals to divide staff into teams that work in tandem on alternate days or every 3rd day (based on the number of healthy staff available, inpatient beds, and patient workload). In hospitals/clinics, all health-care professionals to wear regular surgical masks, wear gloves, follow hand hygiene, and disinfect all surfaces in between patients. Maintain social distancing at all times - with patients and with colleagues. At least 6 ft of space in waiting area between patients, in the outpatient department between patient and doctor, and other places in between staff. If someone is contaminated/positive, the hospital/facility is NOT shut down or everyone quarantined. Only those with close contact are tested and isolated (definition of close contact used in Hong Kong was at least 15 min interaction at <6 feet without surgical mask). Less significant contacts to be self-monitored for symptoms and temperature recorded twice a day. Goggles, headgear, N95 particle filter masks, and double gloves to be reserved for interaction with COVID-19 positive cases or for procedures where respiratory aerosols might be generated - like intubation. For patients with symptoms suggestive of COVID-19 (low-grade fever, dry cough, cold, body ache, fatigue, diarrhea, and breathlessness) or family contact with COVID-19 positive case need to be dealt with as per the government directive, referred to dedicated COVID-19 health-care facility and treated by their separate team of health-care professionals.

Multicenter Epidemiologic Study of Coronavirus Disease-Associated Mucormycosis, India.

During September-December 2020, we conducted a multicenter retrospective study across India to evaluate epidemiology and outcomes among cases of coronavirus disease (COVID-19)-associated mucormycosis (CAM). Among 287 mucormycosis patients, 187 (65.2%) had CAM; CAM prevalence was 0.27% among hospitalized COVID-19 patients. We noted a 2.1-fold rise in mucormycosis during the study period compared with September-December 2019. Uncontrolled diabetes mellitus was the most common underlying disease among CAM and non-CAM patients. COVID-19 was the only underlying disease in 32.6% of CAM patients. COVID-19-related hypoxemia and improper glucocorticoid use independently were associated with CAM. The mucormycosis case-fatality rate at 12 weeks was 45.7% but was similar for CAM and non-CAM patients. Age, rhino-orbital-cerebral involvement, and intensive care unit admission were associated with increased mortality rates; sequential antifungal drug treatment improved mucormycosis survival. The COVID-19 pandemic has led to increases in mucormycosis in India, partly from inappropriate glucocorticoid use.

SARS-CoV-2 viral sepsis with meningoencephalitis.

SARS-CoV-2 predominantly involves the lungs producing acute lung injury, but it can also give rise to a variety of complications involving the central nervous system, gastrointestinal system, kidney and also viral sepsis. With this case report, we are discussing unusual series of complication from acute lung injury, followed by viral sepsis then encephalitis, followed by progressive macrophage activation syndrome.

Safety and efficacy of tocilizumab in the treatment of severe acute respiratory syndrome coronavirus-2 pneumonia: A retrospective cohort study.

Background: Cytokine release storm (CRS) in severe acute respiratory syndrome coronavirus-2 (SARS CoV-2) is thought to be the cause for organ damage and death which is independent of the actual viral burden. Tocilizumab (TCZ), an interleukin-6 receptor antagonist, is approved for the treatment of CRS. We describe the efficacy and safety of TCZ in SARS CoV-2 pneumonia. Methods: This retrospective study was conducted at a tertiary care hospital from April 20 2020 to May 21 2020. The primary endpoint was the cumulative incidence of a composite of either need for admission to the intensive care unit (ICU) with invasive mechanical ventilation or death. Safety outcomes included an increase in liver transaminases and/or evidence of infection. Results: A total of 20 patients received TCZ during the study period. The median age was 54 years (95% confidence interval [CI] 47-63). About 85% of the patients were male. Nearly 70% of the patients had at least one comorbidity. About 55% required ICU admission. The median duration of ICU stay was 11 days (95% CI: 3-13 days). The cumulative incidence of the requirement for mechanical ventilation, clinical improvement and mortality was 11% (95% CI: 0.03%-1%), 74% (95% CI 37%-89%) and 25% (95% CI: 11%-63%), respectively. There was no difference in outcomes according to age, gender or computed tomography severity score. Asymptomatic transaminitis was the most common drug reaction (55%), and one patient developed bacteraemia. Conclusions: TCZ is likely a safe and effective modality of treatment for improving clinical and laboratory parameters of SARS CoV-2 patients with a reduction in ICU stay and ventilatory care need.
