Abstract: Individuals with Type-2 diabetic mellitus (T2DM) along with several other disease-causing factors are impacted adversely by the SARS-CoV-2 pandemic. In India, BBV-152 (CovaxinTM) and ChAdOx1-nCOV (CovishieldTM) vaccines are now being used to limit the spread of SARS-CoV-2 Infection. Adaptive immunity like humoral and T-cell-mediated immunity has a vital role in eliminating SARS-CoV-2. In order to control the disease's course, the infected cells are being destroyed predominantly by cytotoxic CD8+ T cells as well as specific antibodies against SARS-CoV-2 which have the potential to neutralize the virus. This cross-sectional study was done to identify the specific antibodies for SARS-CoV-2 in serum samples from those individuals with and without T2DM by using WANTAI SARS-CoV-2 Total Ab ELISA Kit. The present study comprises 354 study participants, among them T2DM was present in 141 (39.8%) cases and 213 (60.2%) were non-diabetic patients. Hypertension was observed in 95 (26.1%) participants and 259 (73.1%) participants were normotensive. The study participants with T2DM demonstrated lower levels of SARS-CoV-2 total antibodies having an average of 5 AU/ml over those individuals without diabetes showing an average of 12 AU/ml. Among the hypertensive patients, the total antibody levels of SARS-CoV2 are were substantially lowered to showing an average of 8 AU/ml as compared to normotensive subjects showing an average of 14 AU/ml. The results of the current study suggest that regular monitoring of the total SARS-CoV-2 antibody profile may be a useful strategy for assisting people with T2DM and hypertension in determining whether they require SARS-CoV-2 precautionary doses to maintain immunity and protect against infections.
