Dear Editor,
Diabetes mellitus (DM) is considered one of the fastest-growing epidemic diseases of the 21st century, with a high prevalence of approximately 2%–6% worldwide.[1] It is a multifactorial metabolic syndrome. The clinical manifestation of uncontrolled hyperglycemia together with disturbances in metabolism carbohydrate, fat, and protein metabolism resulting from defects in insulin secretion, insulin action, or both.[2] We read the article by Menezes et al.[3] and we must congratulate the authors for bringing out this important analysis. However, we have few important observations and suggestions to make.
First, can the authors highlight what was the period during which the study was performed? This is important since during the corona period most of the studies were at halt due to reduction in patient volume and if the study was performed during COVID-19 times, then COVID-19 screening protocol and consent deserve a mention in the methodology.
Second, what was the criteria for choosing normal control, based on fasting and postprandial blood sugar levels or Hb1Ac was also taken into account is not highlighted in the study. Can the authors throw light over this for the benefit of the readers.
Finally, what was the reason was excluding severe nonproliferative diabetic retinopathy (PDR) and PDR patients. This along with Type 1 DM patients which were not taken for analysis is missing in the exclusion criteria. This needs clarification. Once again we would like to congratulate the authors for bringing out this important analysis.
