Background: Irrespective of the cause of kidney injury, development of renal fibrosis may likely result after prolong insult by the etiologic agent. Inflammatory process associated with an increase in number and activity of mast cell (MC) has been implicated in the development of renal fibrosis. Renal fibrosis occurs through the activation of MC by immunoglobulin E (IgE) binding to high-affinity receptor on its surface. After IgE binding, MC release inflammatory mediators such as histamine, MC protease, cytokines, and chemokines. Aim: This study was designed to investigate the possible role of IgE in the development of renal complication in subjects with Type 2 diabetes. Materials and Methods: A total number of 165 subjects comprising ninety obese diabetic cases (test group) and 75 nondiabetic controls were recruited in this study. The test group was further divided into those with poor glycemic control (n = 45) and those with good glycemic control (n = 45) using glycated hemoglobin (HbA1c). Urine microalbumin was determine using turbidimetry immunoassay, C-reactive protein (CRP) using latex-enhanced immunoturbidimetry assay, IgE, insulin, chymase, and tryptase were estimated using ELISA and HbA1c were estimated by high-performance liquid chromatography. Results: There was statistically significant difference in the mean values of microalbumin, IgE, CRP and HbA1c, chymase, and tryptase in the test group compared with controls (P < 0.01). We found a positive correlation between microalbumin excretion rate and IgE, HbA1c, tryptase, and chymase (P < 0.01). Conclusion: The findings of this study suggest that glycemic control associated inflammatory process involving MC degranulation may contribute to the development of diabetic nephropathy.
