ABSTRACT
Altered body composition and cytokine production due to SARS-CoV-2 antigens may affect homeostasis model assessment for insulin resistance (HOMA-IR) after SARS-CoV-2 infection. To elucidate this phenomenon, we conducted a longitudinal study involving 47 COVID-19 patients, who were followed up for 12 months. During recruitment, body composition and glucose indices were measured, and heparin blood samples were collected for measuring cytokine production. HOMA-IR was considered an elevated or non-elevated group based on the ratio between HOMA-IR at 12 months and 1 month of convalescence. Those with elevated HOMA-IR had a significantly higher body mass index, body fat percentage, and visceral fat rating and had a lower lean mass and lean/fat mass ratio than their counterparts. During the convalescent period, the elevated HOMA-IR group had lower TNFα, IFNγ, IL-2, IL-10, and granzyme B expression levels but had higher TNFα/IL-10, IFNγ/IL-10, IL-2/IL-10, and granzyme B/IL-10 ratios than the other group. The reduced cytokine production and pro-/anti-inflammatory imbalance in patients with elevated HOMA-IR may suggest immune cell dysfunction toward SARS-CoV-2. Patients with elevated HOMA-IR after SARS-CoV-2 infection may experience an increase in BMI and body fat percentage, leading to increased immune dysfunction and chronic inflammatory condition. A nutritional approach and promotion of physical activity may help reduce HOMA-IR and ameliorate glucose indices in these patients.
