A prospective, single-center study to evaluate the clinical performance of Meril ABFind in individuals vaccinated against COVID-19

Background: Accurate rapid antibody detection kits requiring minimum infrastructure are beneficial in detecting post-vaccination antibodies in large populations. ChAdOx1-nCOV (COVISHIELD) and BBV-152 (Covaxin) vaccines are primarily used in India. Methods: In this single-centre prospective study, performance of Meril ABFind was investigated by comparing with Abbott SARS-CoV-2 IgG II Quant (Abbott Quant), GenScript cPass SARS-CoV-2 neutralization antibody detection kit (GenScript cPass), and COVID Kawach MERILISA (MERILISA) in 62 vaccinated health care workers (HCW) and 40 pre-pandemic samples. Results: In the vaccinated subjects, Meril ABFind kit displayed high sensitivity of 93.3% (CI, 89.83%-96.77%), 94.92% (CI, 91.88%-97.96%), and 90.3% (CI, 86.20%-94.4%) in comparison to Abbott Quant, MERILISA, and GenScript cPass respectively. The results of the Meril ABFind in the COVISHIELD-vaccinated group were excellent with 100% sensitivity in comparison to the other three kits. In the Covaxin-vaccinated group, Meril ABFind displayed sensitivity ranging from 80% to 88.9%. In control samples, there were no false positives detected by Meril ABFind, while Abbott Quant, MERILISA, and GenScript cPass reported 2.5%, 10.0%, and 12.5% false positives, respectively. In the pre-pandemic controls, specificity of Meril ABFind was 100%, Abbott Quant 97.5%, MERILISA 90%, and GenScript cPass 87.5%. Conclusion: The Meril ABFind kit demonstrated satisfactory performance when compared with the three commercially available kits and was the only kit without false positives in the pre-pandemic samples. This makes it a viable option for rapid diagnosis of post vaccination antibodies.

Retrospective, observational study to see the effect of evogliptin on continuous glucose monitoring (CGM) in T2DM Indian patients: A real-world experience

This study aimed to assess effectiveness of Evogliptin 5 mg through continues glucose monitoring (CGM) in patients with T2DM in retrospective observational real world settings. Overall 6 patients who received Evogliptin as routine clinical practice in management of T2DM were analyzed retrospectively from single center. Data collected from past medical records. FreeStyle Librepro 1.0.6 was used for CGM. CGM was done 15 days prior to adding Evogliptin and repeated immediately after that for next 15 days. Mean BG level, Percentage time in target range (80-140mg/dl), Percentage time above target and Percentage time below target were assessed prior and after adding Evogliptin in existing treatment regimen. Significant reduction in Mean blood glucose level seen after adding Evogliptin in existing treatment regimen from 215 mg/dl to 138 mg/dl (-77 mg/dl P=0.006). Significant improvement seen in Percentage time in target range (80-140mg/dl) from 17% to 44% (27% P value 0.007) and in Percentage time above target from 81% to 43% (- 38%, P valve 0.003). 13.5 % of the patients seen below target. Evogliptin was found to be effective when added to the patients who were uncontrolled on other oral anti-diabetic medications. It effectively showed improvement in continues glucose monitoring (CGM) parameters like Mean blood glucose, more number of patients were in Time in Target range i.e (80-140mg/dl) after adding Evogliptin to existing anti-diabetic medications & well tolerated.
