[Cardiometabolic and cardiorenal syndromes interactions in Algerian diabetic-hypertensive patient: interest of predictive multi-biomarkers strategy to renal dysfunction].

Unlabelled: The coexistence of essential hypertension (EH) in type 2 diabetic (T2D) patients greatly enhances chronic kidney disease.

Objectives: To assess the acute renal dysfunction in two cohorts of diabetic-hypertensive subjects. The inaugural pathology for each group is either T2D or EH.

Patients And Methods: The study was undertaken on 506 subjects who were divided in 5 groups according to age and sex: diabetic, hypertensive, diabetic- hypertensive (DH and HD) and healthy groups. Patients were phenotyped regarding their cardiometabolic syndrome (CMS) profile using the NCEP/ATPIII criteria and cardiorenal syndrome (CRS) according to the International kidney foundation. Hypertension was defined as systolic (SBP) and diastolic (DBP) blood pressure ≥ 140/90 mmHg, respectively. Insulin resistance (IR) was assessed by Homa-IR model. Glomerular filtration rate (GFR) by creatinine clearance. CMS and CRS parameters were determined on Cobas®. The SBP and DBP measurements by electronic blood pressure using Omron 705 CP® type.

Results: IR was found in all diabetics and hypertensive patients. Dyslipidemia are correlated to % body fat mass accretion in all groups. In DH group, the renal disorder is confirmed by decreased GFR (30%) and increased microalbuminuria (> 30 mg/24h); associated with increased NT-pro BNP and plasma aldosterone depletion.

Conclusion: Several biomarkers are necessary to detection kidney disease and renal failure prevention in diabetic patients to hypertensive state. The renal dysfunction was significantly related to T2D-EH disease.
