The Role of Metalloendopeptidase (Mep) As A Vital Predictor of Early Diabetic Nephropathy and Its Relationship To Some Other Biochemical Variables

Metalloendo peptidase is a neutral endopeptidase that cleaves peptides at the amino side of hydrophobic residues and inactivates several peptide hormones, including atrial natriuretic factor, giucagon, enkephalin, substance p, neurotensin, oxytocin, and bradykinin. it is also a major enzyme for the degradation of beta-amyloid. this study aimed to measure enzyme activity and compare it with other biochemical changes in sera patients with diabetic nephropathy. the study included 35 pathological samples of people with diabetic nephropathy, 24 samples from males and 11 samples from females, as well as the same number of healthy people as a comparison group of 15 males, 20 females, with the ages of both groups of patients with diabetic nephropathy and the healthy ranging between (60-35) years. when compared with healthy controls, a significant change (p 0.001) was seen in each of age, sbp, dbp, fbs, hba1c, homa, ldl, vldl, tag, tc, urea, creatinine, and uric acid over the period of september 2020 - december 2020. while there was a substantial drop (p 0.001) in both insulin and hdl when compared with the control group, there was no significant change (p 0.331) in bmi. as for the enzyme and cystatin-c, a significant change (p <0.001) was observed in the serum of patients with diabetic nephropathy compared with healthy subjects. also, there was a positive correlation relationships between the enzyme and each of cystatin - c, age, sbp, insulin, homa, hba1c, fbs, dbp, creatinine, urea, and uric acid while a negative correlation between the enzyme and bmi, dbp, tc, tag, vldl, hdl, and ldl was observed. we can conclude from the results that the enzyme activity increases significantly in the serum of patients with diabetic nephropathy compared with healthy controls. this is due to damage to the kidney's tissues and cells, which results in the enzyme's release into the bloodstream and increased activity there. because the enzyme is prevalent in renal tissues. it should be used as a clinical variable in patient diagnosis as an early predictor of disease.
