The 'myth of Hydroxychloroquine (HCQ) as post-exposure prophylaxis (PEP) for the prevention of COVID-19' is far from reality.

The efficacy of Hydroxychloroquine (HCQ) as post-exposure prophylaxis (PEP) for the prevention of COVID-19 was contentious. In this randomized control double-blind clinical trial, asymptomatic individuals with direct contact with laboratory-confirmed COVID-19 cases were randomized into PEP/HCQ (N = 574) and control/placebo (N = 594) group. The PEP/HCQ group received tablet HCQ 400 mg q 12 hourly on day one followed by 400 mg once weekly for 3 weeks, and the control/Placebo group received matching Placebo. The incidence of COVID-19 was similar (p = 0.761) in PEP [N = 24 out of 574, (4.2%)] and control [N = 27 out of 594, (4.5%)] groups. Total absolute risk reduction for the incidence of new-onset COVID-19 was -0.3% points with an overall relative risk of 0.91 (95% confidence interval, 0.52 to 1.60) and the number needed to treat (NNT) was 333 to prevent the incident of one case of COVID-19. The study found that, PEP with HCQ was not advantageous for the prevention of COVID-19 in asymptomatic individuals with high risk for SARS-CoV-2 infection. Though HCQ is a safer drug, the practice of irrational and indiscriminate use of HCQ for COVID-19 should be restrained with better pharmacovigilance.

Clinical Profile of Patients Admitted With Mucormycosis During the COVID-19 Pandemic in Medicine Emergency of a Tertiary Care Hospital in North India.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which has taken the world as a storm, has been indisputably found to be associated with mild to life-threatening pneumonia in the majority of patients. Mucormycosis emerged as a life-threatening complication of coronavirus disease 2019 (COVID-19) in India during the second wave of the COVID-19 pandemic. There lies a large lacuna in the understanding of the disease progression and the association of mucormycosis with COVID-19 and the various predisposing factors. AIM: To assess the pattern, risk factors, and outcome of mucormycosis cases reported to hospitals in North India during the second wave of the COVID-19 pandemic. MATERIAL AND METHODS: An observational, prospective study was conducted for 109 patients reporting to a medical emergency with a history of suspected or confirmed mucormycosis from May 2021 to July 2021. Obtained data were analysed using descriptive statistics and results were expressed as a percentage and mean. RESULTS: Out of 109 patients, 75 were male and 34 were female with a mean age of 50.6 years, most cases belong to the rural background. The most common types of mucormycosis were rhino-orbital (34.8%), rhino-orbital cerebral (20.18%), and pulmonary (23.8%). The most common risk factors were uncontrolled diabetes (80 %), use of steroids (68.8%), diabetic ketoacidosis (42%), and COVID-19 positive status (66.9%). High mortality of 33.9% was seen in our study. CONCLUSIONS: The most vulnerable group in our study were patients with pulmonary manifestations (51.4%) and patients requiring oxygen therapy (94.6%). Our study found that scoring systems namely the quick sequential organ failure assessment (q SOFA) scoring system (p-value <0.001) along with the Glasgow Coma Scale (p-value <0.038) can be used as a prognostic indicator and good assessment tools for the degree of severity of disease at an early stage.

Paradigm Shift in Pattern & Prevalence of Poisoning During Covid-19 Pandemic.

Poisoning and drug overdose are the medical emergencies in which it is important to identify the incidence, pattern and the outcome in order to take relevant steps for stringent planning not only at the hospital level but also at the community level for its prevention and management. The current pandemic of COVID-19 has had a tremendous effect on the psychological state of the people. MATERIAL: An observational, prospective study was conducted for 100 patients reporting to medical emergency with history of poisoning intake from April 2020 to January 2021. Age range was 14-85 years. Obtained data were analysed using descriptive statistics and results were expressed as percentage and mean. OBSERVATION: Out of 100 patients (77M,33F), mean age of 32.6 years, most cases belong to age group of 20-30 years and 50% were matriculates and majority of the patients belonged to Punjab and Himachal Pradesh. The most common poisoning agents consumed were corrosives (34%) followed by cellular toxins (24%). Respiratory distress (53%), loss of consciousness (43%), acute kidney injury (36%) were the common clinical presentations. PSS (Poisoning Severity Score) was moderate in 52% of patients, 14% had severe, 16% of patients had fatal PSS scores and 18% of patients had minor PSS. 16 patients with fatal PSS and 16 patients with moderate to severe PSS got expired. High mortality of 33% was seen in our study. CONCLUSION: The most vulnerable group in our study was of young males in age group of 21-30 years and less educated, who had lost their jobs due to Covid-19 pandemic lockdown. Corrosives were the most commonly consumed poison during lockdown. Our study found that scoring systems PSS and GCS were good assessment tools for degree of severity of poisoning at an early stage.

Clinical Profile and Outcomes of Diabetic Ketoacidosis during the COVID-19 Pandemic in North India.

Although recent data have shown a declining trend in mortality in diabetic ketoacidosis (DKA), the outcomes are likely to be different during the coronavirus (COVID-19) pandemic. We conducted a prospective cohort study to evaluate the spectrum and outcomes of adult DKA during the pandemic and document differences in DKA patients with or without COVID-19. A total of 169 patients (mean age 44 years) were admitted at the Emergency Department of PGIMER, Chandigarh (India), from January 2020 to June 2021. The precipitating factors were noncompliance with antidiabetic therapy (77.5%), infections (62.7%), and noninfectious conditions (21.3%). Thirty-nine (23.1%) patients had COVID-19, including 31 with severe infection. DKA severity and resolution, ventilator requirement, hospital stay, and mortality were similar in the patients with or without COVID-19. In-hospital mortality was 39.6% (n = 67). The independent mortality predictors were ventilator requirement (p-0.000), an infection trigger (p-0.049), and hyperosmolarity (p-0.048). DKA mortality is increased significantly during the pandemic.

Mental Health Outcomes of Perceived Stress, Anxiety, Fear and Insomnia, and the Resilience among Frontline Nurses Caring for Critical COVID-19 Patients in Intensive Care Units.

Background: The coronavirus disease-2019 (COVID-19) pandemic has led to a significant disruption in healthcare delivery and poses a unique long-term stressor among frontline nurses. Hence, the investigators planned to explore the adverse mental health outcomes and the resilience of frontline nurses caring for COVID-19 patients admitted in intensive care units (ICUs). Materials and methods: A cross-sectional online survey using Google form consisted of questionnaires on perceived stress scale (PSS-10), generalized anxiety disorder scale (GAD-7), Fear Scale for Healthcare Professionals regarding the COVID-19 pandemic, insomnia severity index, and the Connor-Davidson Resilience Scale-10 (CD-RISC) were administered among the nurses working in COVID ICUs of a tertiary care center in North India. Results: A considerable number of subjects in the study reported symptoms of distress (68.5%), anxiety (54.7%), fear (44%), and insomnia (31%). Resilience among the frontline nurses demonstrated a moderate to a high level with a mean percentage score of 77.5 (31.23 ± 4.68). A negative correlation was found between resilience and adverse mental outcomes; hence, resilience is a reliable tool to mitigate the adverse psychological consequences of the COVID-19 pandemic. Conclusion: Emphasizing the well-being of the nurses caring for critical COVID-19 patients during the pandemic is necessary to enable them to provide high-quality nursing care.

Serum iron indices in COVID-19-associated mucormycosis: A case-control study.

BACKGROUND: Whether dysregulated iron metabolism is associated with COVID-19-associated mucormycosis (CAM) remains unknown. Herein, we compare the serum iron indices in COVID-19 subjects with and without mucormycosis. METHODS: We conducted a case-control study enrolling COVID-19 participants with and without mucormycosis. We compared the baseline serum iron indices (iron, ferritin, total iron-binding capacity [TIBC], unsaturated iron-binding capacity and percentage transferrin saturation) between CAM cases and COVID-19 controls. Additionally, we performed a multivariate logistic regression analysis to assess whether any iron indices are associated with CAM. RESULTS: We enrolled 28 CAM cases (mean age 53.6 years old; 78.6% men) and 26 controls (mean age 57.2 years old; 73.1% men). Rhino-orbital (±cerebral) mucormycosis (85.7%) was the most clinical presentation. Diabetes mellitus was more frequent in the cases than controls (75% vs. 42.3%; p = .015). Hypoxaemia during COVID-19 illness was more common in controls than cases. The mean serum iron values (33 vs. 45 µg/dl, p = .03) and TIBC (166.6 vs. 201.6 µg/dl, p = .003) were significantly lower in CAM cases than controls. On multivariate analysis, we found a lower TIBC (odds ratio [OR] 0.97; 95% confidence interval [CI], 0.95-0.99) and diabetes mellitus (OR 5.23; 95% CI, 1.21-22.68) to be independently associated with CAM after adjusting for serum iron, ferritin and glucocorticoid therapy. The case fatality rate of CAM was 73.9%. The iron indices were not significantly different between CAM survivors and non-survivors. CONCLUSIONS: The CAM is associated with lower TIBC levels than COVID-19 subjects without mucormycosis, suggesting dysregulated iron metabolism in its pathogenesis. Further studies are required to confirm our preliminary observations.

High-resolution intracranial vessel wall imaging in cerebral viral infections evaluations.

PURPOSE: Vascular complications can be seen in various viral CNS infections. Variable neuro-imaging findings have been described in the literature elucidating the parenchymal changes with vascular involvement. Vessel wall imaging (VWI) can help to detect these vascular involvements. We aimed to describe the role and usefulness of VWI in the evaluation of various viral CNS infections. METHODS: In this prospective study, we included 15 cases of various diagnosed viral CNS infections (varicella, HIV encephalopathy, HSV encephalitis, Japanese encephalitis, dengue, COVID-19). VWI and time-of-flight MR angiography (TOF MRA) were included in imaging protocol. All cases were evaluated for the presence of cerebral parenchymal changes, vascular enhancement, and vascular stenosis. RESULTS: We found infarctions in all 5 cases of varicella, 1 case of HIV encephalopathy, and 1 case of COVID-19 encephalopathy. All these cases also showed vascular enhancement and stenosis on VWI. The rest of the cases, including 1 case of HIV encephalopathy, 3 cases of herpes encephalitis, 2 cases of dengue, and 2 cases of Japanese encephalitis did not have any vascular complication, and also did not show vascular enhancement or stenosis. CONCLUSION: VWI can be useful in the detection of vascular involvement in various viral infections of CNS which show a relatively higher cerebrovascular complication rate like varicella, HIV encephalopathy, and COVID-19. However, VWI may not be useful in the routine evaluation of other viral infections like herpes, dengue, and Japanese encephalitis, which have a very low rate of cerebrovascular complication rate.

Is there an association between zinc and COVID-19-associated mucormycosis? Results of an experimental and clinical study.

BACKGROUND: The enormous increase in COVID-19-associated mucormycosis (CAM) in India lacks an explanation. Zinc supplementation during COVID-19 management is speculated as a contributor to mucormycosis. We conducted an experimental and clinical study to explore the association of zinc and mucormycosis. METHODS: We inoculated pure isolates of Rhizopus arrhizus obtained from subjects with CAM on dichloran rose Bengal chloramphenicol (DRBC) agar enriched with (three different concentrations) and without zinc. At 24 h, we counted the viable colonies and measured the dry weight of colonies at 24, 48 and 72 h. We also compared the clinical features and serum zinc levels in 29 CAM cases and 28 COVID-19 subjects without mucormycosis (controls). RESULTS: We tested eight isolates of R arrhizus and noted a visible increase in growth in zinc-enriched media. A viable count percentage showed a significantly increased growth in four of the eight isolates in zinc-augmented DRBC agar. A time- and concentration-dependent increase in the mean fungal biomass with zinc was observed in all three isolates tested. We enrolled 29 cases of CAM and 28 controls. The mean serum zinc concentration was below the reference range in all the subjects and was not significantly different between the cases and controls. CONCLUSIONS: Half of the R arrhizus isolates grew better with zinc enrichment in vitro. However, our study does not conclusively support the hypothesis that zinc supplementation contributed to the pathogenesis of mucormycosis. More data, both in vitro and in vivo, may resolve the role of zinc in the pathogenesis of CAM.

Severe Acute Respiratory Infection Surveillance during the Initial Phase of the COVID-19 Outbreak in North India: A Comparison of COVID-19 to Other SARI Causes.

INTRODUCTION: World Health Organization proposes severe acute respiratory infection (SARI) case definition for coronavirus disease 2019 (COVID-19) surveillance; however, early differentiation between SARI etiologies remains challenging. We aimed to investigate the spectrum and outcome of SARI and compare COVID-19 to non-COVID-19 causes. PATIENTS AND METHODS: A prospective cohort study was conducted between March 15, 2020, to August 15, 2020, at an adult medical emergency in North India. SARI was diagnosed using a "modified" case definition-febrile respiratory symptoms or radiographic evidence of pneumonia or acute respiratory distress syndrome of ≤14 days duration, along with a need for hospitalization and in the absence of an alternative etiology that fully explains the illness. COVID-19 was diagnosed with reverse transcription-polymerase chain reaction testing. RESULTS: In total, 95/212 (44.8%) cases had COVID-19. Community-acquired pneumonia (n = 57), exacerbation of chronic lung disease (n = 11), heart failure (n = 11), tropical febrile illnesses (n = 10), and influenza A (n = 5) were common non-COVID-19 causes. No between-group differences were apparent in age ≥60 years, comorbidities, oxygenation, leukocytosis, lymphopenia, acute physiology and chronic health evaluation (APACHE)-II score, CURB-65 score, and ventilator requirement at 24-hour. Bilateral lung distribution and middle-lower zones involvement in radiography predicted COVID-19. The median hospital stay was longer with COVID-19 (12 versus 5 days, p = 0.000); however, mortality was similar (31.6% versus 28.2%, p = 0.593). Independent mortality predictors were higher mean APACHE II in COVID-19 and early ventilator requirement in non-COVID-19 cases. CONCLUSIONS: COVID-19 has similar severity and mortality as non-COVID-19 SARI but requires an extended hospital stay. Including radiography in the SARI definition might improve COVID-19 surveillance.

Clinical spectrum and outcome of patients visiting coronavirus screening centre in North India and clinical predictors for COVID-19.

AIM: The aim of this study is to elucidate the demographics, symptoms and outcome of sick persons visiting coronavirus (COVID) screening OPD of a tertiary institute in North India. STUDY DESIGN: The present descriptive, prospective study was done on 1030 patients and information about presenting symptoms, demographics (age, sex, nationality, residence), contact and travel history, comorbidities etc., were recorded. On the basis of criteria given by Indian Council of Medical Research, patients were divided into suspected (SARS-CoV-2) and non-suspected group. Of the suspected patients, with RT-PCR test positive were classified as confirmed COVID-19 case and negative RT-PCR symptomatic individual were defined as negative COVID-19 case. RESULTS: Out of the total patients, 65.6% were male and 34.4% were females. The mean age was 37.04 years. Fever 49.3%, cough 57.1% and sore throat 43.5% were the main symptoms. Comorbidities were seen in 8.5% patients with hypertension (3.5%) and diabetes mellitus (3.4%). Forty patients were positive. Highly significant correlation (P < 0.01) was found between COVID-19 positive status and in patients without any symptoms, between COVID-19 and cough and sore throat, between COVID-19 and comorbidity (diabetes mellitus), between COVID-19 and high-risk exposures (resident of hot spot and history of contact with confirmed case). Our study also found COVID-19 positive status, shortness of breath and tachycardia as independent predictors of mortality (P < 0.05). CONCLUSIONS: Most of the patients were young adults and males were mainly affected. Main presentation was cough followed by fever. Infectivity was higher in patients who had underlying comorbid diseases, especially diabetes and chronic kidney disease. Critical patients with decreased oxygen saturation, tachypnoea and tachycardia had strong predictability for COVID-19 positivity. COVID-19 positive status, shortness of breath and tachycardia are important predictors of mortality.

Post-exposure prophylaxis with hydroxychloroquine for the prevention of COVID-19, a myth or a reality? The PEP-CQ Study.

Many drugs have been tried for the treatment/prevention of COVID-19 with limited success. Direct household contacts of COVID-19 patients are at highest risk for SARS-CoV-2 infection. Hydroxychloroquine (HCQ) has been tried against COVID-19 owing to its in vitro virucidal action against SARS-CoV-2, but the role of HCQ as post-exposure prophylaxis (PEP) remains inconclusive. In this open-label, controlled clinical trial, asymptomatic individuals who had direct contact with laboratory-confirmed COVID-19 cases or had undertaken international travel in the last 2 weeks were offered HCQ prophylaxis and assigned to PEP (n = 132) or control (n = 185) group. The PEP group received HCQ 800 mg on Day 1 followed by 400 mg once weekly for 3 weeks. Both groups undertook home quarantine for 2 weeks along with social distancing and personal hygiene. Over 4-week follow-up, 50/317 participants (15.8%) had new-onset COVID-19. The incidence of COVID-19 was significantly (P = 0.033) lower in the PEP (14/132; 10.6%) compared to the control (36/185; 19.5%) group (total absolute risk reduction, -8.9% points). The NNT to prevent the occurrence of 1 COVID-19 case was 12. Overall relative risk was 0.59 (95% CI 0.33-1.05). Compliance was good. The most common adverse event was epigastric discomfort with burning sensation (three participants), with no serious adverse events. PEP with HCQ has the potential for the prevention of COVID-19 in at-risk individuals. Until definitive therapy is available, continuing PEP with HCQ may be considered in suitable at-risk individuals. Further randomised clinical trials with larger samples are required for better evaluation of HCQ as PEP for COVID-19 prevention.
