Abstract

Background: Hypertention and diabetes are important risk factors for cardiovascular disease. studies have shown that microalbuminuria is a strong predictor of cardiov-ascular disease in different population.In this study the relation of microalbuminuria with diabetes and hypertention as risk factors of atherosclerosis disease were investi-gated.

Methods: Two hundered twenty eight patients with angiographically confirmed coronary atherosclerotic lesions, (mean age 60 ± 0.5 SD) referred to Madani Hospital, Tabriz, Iran were studied .This patients according to the number of diseased vessels were classified in two groups. The levels of glucose and creatinine and that of post parandial glucose were determined in venous blood samples by standard methods. Immunoturbidimetric method was employed in the measurement of microalbuminuria. The results were analysed by statistical tests.

Results: The increased albumin/creatinine ratio was markedly correlated with fasting blood sugar, systolic and diastolic blood pressure (P < 0.05 in all cases). Significant correlation was noticed between microalbuminuria, diabetes according to the extension of the disease lesions (P < 0.05). No relationship was observed between microalbumin-uria, high levels of blood pressure according to the number of diseased vessels (P > 0.05).  Conclusion: The relationship between diabetes and microalbuminuria was meaningful. According to atherosclerotic lesions a marked correlation was also noticed between microalbuminuria and diabetes. These facts may contribute to the higher cardiovascular risk in diabetic patients. An associated between hypertension and microalbuminuria was noticed. The result suggests that although risk factors such as hypertension and diabetes are known to cause cardiovascular disease, microalbuminuria may in fact be a better indicator of established microvascular damage and better predictor of cardiov-ascular events.

Abstract
Background: Microalbuminuria (MA) is associated with increased cardiovascular risk in hypertensive patients, but not many studies have specifically examined the effects of MA-lowering on regression of left ventricular hypertrophy (LVH) among pediatric patients with hypertension.
Methods: Fifty-five patients with essential hypertension, 11 to 19 years old were prospectively studied. All patients received concomitant therapy of hydrochlorothiazide and angiotensin-converting-enzyme inhibitor. Five patients also required angiotensin-receptor blocker to achieve the blood pressure goal. Baseline and 12-month follow-up measures of left ventricular mass index (LVMI) determined by echocardiography and urine microalbumin/creatinine ratio (MA/Cr) were collected. MA was defined as MA/Cr>30. LVH was defined as LVMI>38.6 g/m2. The primary end points were 25% or more reductions in MA and the LVMI.
Results: Weight (r=0.83), body surface area (r=0.85), body mass index (BMI) (r=0.86), systolic blood pressure (SBP) (r=0.57), diastolic blood pressure (DBP) (r=0.49), mean arterial pressure (r=0.53) and MA (r=0.87) were all univariate correlates of LVMI. In a multiple regression analysis, MA, BMI and SBP were significant correlates of LVMI. MA alone explained 76% of the variance of LVMI, whereas BMI and SBP explained only 1.6% and 0.4% of the variance, respectively. MA was the most significant correlate of follow-up LVMI after BMI and SBP were included in the overall multiple regression models.
Conclusion: MA is a strong predictor of LVH in hypertensive children and adolescents. MA-lowering halts the progression of LVH or induces its regression.

Abstract
Background: Patients with type 2 diabetes mellitus (T2DM) are diagnosed with a wide range of renal damage, usually presenting with albuminuria and decreased estimated Glomerular Filtration Rate (eGFR). Some patients have only albuminuria and normal eGFR, while others have normoalbuminuria even in advanced stages of chronic kidney disease. This study investigated and followed the course of diabetic nephropathy in patients with T2DM.
Methods: 1107 patients with T2DM were enrolled in the study. This historical cohort was conducted between the years 2017 and 2022. Patients with confirmed type 2 DM, referred to the diabetes clinic of Vali-Asr Hospital, affiliated with the Tehran University of Medical Science. Complete medical history, blood pressure, and laboratory data were obtained in the first and follow-up visits. Follow-up was every 3 to 6 months for 30 months. Every year, 24-hour urinary albumin was measured, and eGFR was estimated based on the Cockcroft-Gault formula.
Results: Male sex, age, disease duration, weight, systolic blood pressure, 2 hours postprandial (2hpp) glucose, serum triglyceride, and uric acid significantly correlated with albuminuria. At the initiation of the study, the highest eGFR values occurred in microalbuminuric patients, followed by a sharp decrease. No significant correlation was found between eGFR and albuminuria in most patients, and more than half of them with eGFR of less than 60 ml/min/m2 still had normal albuminuria
Conclusion: This study showed that patients with microalbuminuria and normoalbuminuria had the highest eGFR values followed by macroalbuminuria, but patients with normoalbuminuria and microalbuminuria had an initial increase and then a decrease, and the macroalbuminuria group showed the sustained and greatest decrease during the follow-up period. Serial surveillance of both albuminuria and GFR is crucial in T2DM.
