Clinical Profile of Coronavirus Disease 2019 Comparing the First and Second Waves: A Single-Center Study from North India.

Background and Objectives: Severe acute respiratory syndrome coronavirus 2, caused by the novel coronavirus disease 2019 (COVID-19), led to a devastating pandemic that hit majority of the countries globally in a wave-like pattern. The characteristics of the disease varied in different geographical areas and different populations. This study highlights the epidemiological and clinical characteristics of COVID-19 during two major waves in North India. Materials and Methods: Clinical characteristics and outcomes of all COVID-19-reverse transcription-polymerase chain reaction-positive patients, admitted from March 2020 to June 2021, to a tertiary care center in North India, were studied retrospectively. Results: During this period, total of 5652 patients were diagnosed having COVID. Patients who were incidentally diagnosed as COVID-positive (n=667) with other unrelated comorbid conditions and patients admitted under level 1 facility (n=1655; 1219 from first and 436 from second wave) were excluded from final analysis. Males were most commonly affected in both waves, with male to female ratio 4:1 in first and 3:1 in second wave. First wave had significantly more people with co-morbidities like diabetes mellitus and hypertension (P=0.001), whereas younger age group (age <40 years) were significantly more affected in second wave (P= 0.000). Fever was the most common presenting complaint in both waves, followed by cough and breathlessness. Patients during first wave had more severe disease at presentation and high mortality compared to the second wave. Conclusion: Majority of the patients with COVID-19 infection presenting to our hospital were young during the second wave. Fever was noted as presenting manifestation. Mortality was low during the second wave as compared to the first wave, likely to be due to proper protocol-based treatment resulting in better outcomes.

Endocrine and Metabolic Manifestations of COVID-19 Patients Admitted to an Intensive Care Unit

Context: The effects of coronavirus disease 2019 (COVID-19) on the endocrine system remain uncertain. Objective: Our study aimed to explore the possible effects of COVID-19 on endocrine organs and to determine the impact of glycemic status, 25-hydroxyvitamin D levels, calcium levels, and thyroid dysfunction on the final outcome of patients with COVID-19. Design and methods: This single-center, retrospective study evaluated endocrine function abnormalities in 102 patients hospitalized with COVID-19 in the intensive care unit (ICU). Results: Of 102 patients admitted to ICU, 42 (41.2%) succumbed to illness. The most frequently observed abnormality in thyroid function tests was low free triiodothyronine (FT3) levels (56%). A thyroid profile indicating thyrotoxicosis was detected in five (4.9%) patients, and overt hypothyroidism was identified in two (1.9%) patients. New-onset diabetes was detected in five (4.9%) patients whereas diabetic ketoacidosis at presentation was found in six (5.9%) cases. Rhino-orbital mucormycosis was detected in one patient with diabetes during treatment of COVID-19 while three (2.9%) patients were diagnosed with pulmonary mucormycosis after recovery from COVID-19. Hypocalcemia was observed in 52 (51 %) patients. Out of 42 patients who died, 32 patients had low FT3, 26 patients had high glycated haemoglobin (HbA1c), and 33 patients had low 25-hydroxyvitamin D. Multivariate analysis demonstrated that low concentration of 25-hydroxyvitamin D, low FT3 and higher HbA1c levels were significantly associated with increased mortality. Conclusion: New-onset thyrotoxicosis in COVID-19 patients is mostly due to subacute thyroiditis. Hypocalcemia is also frequently encountered in patients with moderate disease and those with critical COVID-19. A high index of suspicion is required to timely diagnose mucormycosis in COVID-19 patients with diabetes. 

Coronavirus Disease 2019 Infection Presenting with Renal Infarction: A Rare Case Report.

After its discovery in Wuhan, China, in December 2019, coronavirus disease 2019 (COVID-19) has now become a pandemic in a short period. The kidney involvement is frequently reported, especially in critically ill hospitalized patients. Multiple mechanisms have been proposed for this damage range from direct invasion, cytokine storm, and hemodynamic derangements. Although COVID-19 has been described to have association with hypercoagulable state and thromboembolic events in major blood vessels, renal infarction due to COVID-19 infection is a rare occurrence. We here report a rare case of renal infarction due to COVID-19 infection. This patient initially presented with COVID pneumonia with acute kidney injury. Later on during evaluation of his gastrointestinal complaints, he was detected to have renal infarction by computed tomography angiography.

Comparison of Tocilizumab and High-dose Methylprednisolone Pulse on Outcomes in Severe Corona Virus Disease-2019: TAME-COVID, a Retrospective Multicentric Study.

BACKGROUND: India recently encountered fierce second wave of coronavirus disease (COVID-19), and scarcity of novel medications added to the management challenges. Various studies have highlighted the effectiveness of tocilizumab and high-dose steroids in severe COVIDs, but none has compared their efficacy. MATERIALS AND METHODS: This retrospective multi-centric analysis compares intravenous tocilizumab (8 mg/kg/day, maximum dose-800 mg), and intravenous Methylprednisolone Pulse (MPS-1 g/day for 3 days) in severe COVID-19. Both the groups had additionally received the standard of care COVID treatment as per protocol. Outcomes were assessed at 30 days. RESULTS: A total of 336 patients, with 249 receiving MPS and 87 receiving tocilizumab were compared. Majority of these were males (72.9%) with a mean age of 57.4 ± 13.6 years. Diabetes was the most common comorbidity. Patients in both groups had comparable age distribution, comorbidities, presenting mean-arterial pressures, d-Dimer levels, serum ferritin, serum leukocyte-dehydrogenase, and procalcitonin. However, the tocilizumab group had more number of males, higher incidence of coronary artery disease, more tachypnea and leukocytosis, more number of patients with severe acute respiratory disease syndrome (PaO2/FiO2 ratio <100), and higher C-reactive protein levels at presentation. Both groups had comparable adverse events' profile. Tocilizumab group had lesser requirement of invasive ventilation than MPS group (17% vs. 29%, P = 0.038), however mortality at the end of 30 days follow-up was similar (36% vs. 34% respectively; P = 0.678). CONCLUSIONS: Tocilizumab decreased the need for invasive ventilation in severe COVID-19; however, it did not translate to improved survival. A planned prospective randomized study is recommended in this respect to compare their efficacy.
