COVID-19 associated mucormycosis: A Descriptive Multisite Study from India.

BACKGROUND AND AIMS: Mucormycosis is an invasive fungal infection and carries a significant morbidity and mortality. A number of cases of mucormycosis have been reported in association with COVID-19. In this study, a consortium of clinicians from various parts of India studied clinical profile of COVID-19 associated mucormycosis (CAM) and this analysis is presented here. METHODS: Investigators from multiple sites in India were involved in this study. Clinical details included the treatment and severity of COVID-19, associated morbidities, as well as the diagnosis, treatment and prognosis of mucormycosis. These data were collected using google spreadsheet at one centre. Descriptive analysis was done. RESULTS: There were 115 patients with CAM. Importantly, all patients had received corticosteroids. Diabetes was present in 85.2% of patients and 13.9% of patients had newly detected diabetes. The most common site of involvement was rhino-orbital. Mortality occurred in 25 (21.7%) patients. On logistic regression analysis, CT scan-based score for severity of lung involvement was associated with mortality. CONCLUSION: Universal administration of corticosteroids in our patients is notable. A large majority of patients had diabetes, while mortality was seen in ∼1/5th of patients, lower as compared to recently published data.

Glycemic parameters in patients with new-onset diabetes during COVID-19 pandemic are more severe than in patients with new-onset diabetes before the pandemic: NOD COVID India Study.

BACKGROUND AND AIMS: It is not known if new onset diabetes during Coronavirus-19 disease (COVID-19; NOD COVID) is phenotypically or biochemically different than new onset diabetes before COVID-19 (NOD). METHODS: All adults diagnosed with new onset diabetes from during the time of COVID-19 were compared with new onset diabetes prior to COVID-19 from two tertiary care hospitals in Chennai and Delhi. RTPCR test for SARS-CoV-2 virus was done as appropriate, and COVID-19 antibody test was done in all other NOD COVID patients. RESULT: A total of 555 patients with new onset diabetes were included in the study (282 NOD and 273 NOD COVID patients). Patients with NOD COVID had higher fasting and post prandial blood glucose and glycated hemoglobin levels vs. NOD patients. Both the groups had high average body mass index; ∼28 kg/m2. Interestingly, fasting C-peptide levels were significantly higher in the NOD COVID group vs. NOD group. There was no difference in C-peptide levels or glycemic parameters between the COVID-19 antibody positive and negative NOD COVID cases. CONCLUSION: Individuals who were diagnosed with diabetes during COVID-19 epidemic (NOD COVID) do not significantly differ from those diagnosed before COVID-19 in symptomatology, phenotype, and C-peptide levels but they had more severe glycemia.

The impact of obesity on inflammatory markers used in the assessment of disease activity in rheumatoid arthritis - a cross-sectional study.

INTRODUCTION: Obesity is known to be associated with elevated levels of inflammatory markers. The aim of the study was to assess the confounding effect of obesity on the levels of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in patients with rheumatoid arthritis (RA) in low disease activity state or remission as indicated by clinical disease activity index (CDAI). MATERIAL AND METHODS: Adult RA patients with CDAI less than 10 were divided into two groups: obese and non-obese, based on body mass index. Relevant exclusions were applied to eliminate causes of raised inflammatory markers other than obesity. The difference of CRP and ESR levels between the obese and non-obese groups was analyzed. RESULTS: Obese patients with RA (n = 85) had higher CRP and ESR than non-obese patients (n = 66) (p-values 0.008 and 0.000005, respectively). In addition, obese females with RA had significantly higher CRP and ESR as compared to non-obese females. However, the difference was not significant in males. Twenty-one obese (24.7%) and two non-obese RA patients (3%) had elevated CRP (difference of approximately 22% [24.7 minus 3]). Forty obese (47%) and 16 non-obese RA patients (24.2%) had elevated ESR (difference of approximately 23% [47 minus 24.2]). Thus, obesity was the attributable cause of falsely elevated CRP and ESR in 22% and 23% of patients, respectively. CONCLUSIONS: About one-fifth of patients with RA, who are actually in low disease activity, may have elevated inflammatory markers, primarily because of obesity. Therefore, elevated CRP and ESR in obese patients with RA should be interpreted with caution because it may lead to unnecessary overtreatment.

Dipeptidyl peptidase 4 inhibitors linked bullous pemphigoid in patients with type 2 diabetes mellitus: A series of 13 cases.

BACKGROUND: Dipeptidyl peptidase 4 (DPP4) inhibitors have increasingly been linked to bullous pemphigoid, but there is paucity of data from India where about 1.85 million patients have been estimated to use these drugs. METHODS: In 30,000 patients with T2DM seen by us in two tertiary care centres since 2015, we detected 13 cases of bullous pemphigoid linked to DPP4 inhibitors. We used WHO-UMC (World Health Organisation-Uppsala Monitoring Centre) causality assessment system for assessment. RESULTS: Lesions of bullous pemphigoid appeared at varied intervals (within 1 weeks-2 years) after start of DPP4 inhibitors. Implicated drugs were Linagliptin (n, 8), Vildagliptin (n, 4) and Sitagliptin (n, 1). Mostly, lesions were seen after 60 years age, and over trunk and extremities. Skin biopsy was compatible with bullous pemphigoid in two patients. Lesions regressed within a month of stopping DPP4 inhibitors in 9 patients while delayed regression up to 6 months in 4 patients. Overall, skin lesions remitted in all patients and did not recur. CONCLUSION: Any new bullous lesion appearing while patient is on DPP4 inhibitors should be considered as bullous pemphigoid and should necessitate prompt withdrawal of the drug.
