With the lack of regional differences and the well-standardized status of test results, the RIs derived from this nationwide study can be used for the entire Turkish population.
Urinary NAG excretion is elevated in type II diabetic patients as compared with the healthy individuals. Perindopril/indapamide administration is effective in reducing urinary NAG excretion in these patients, and this effect seems to be independent from blood pressure and glycemia control. Presence of tubular proteinuria may be an early indicator of diabetic renal disease in patients without microalbuminuria. Perindopril (2 mg)/ indapamide (0.625 mg)/o.d. treatment may have beneficial effect on the tubulointerstitial damage in diabetic kidney disease.
Background/Aims: Cardiac valve calcification (CVC) and left ventricular (LV) abnormalities are common indicators of a poor prognosis in dialysis patients. We determined the prevalence of hypertension, CVC, LV hypertrophy (LVH) and LV geometry in peritoneal dialysis (PD) patients. Methods: Eighty-seven patients (50 female; mean age 42 ± 13 years; mean dialysis duration 46 ± 24 months) on strict salt and volume restriction, none of whom were receiving antihypertensives, were included in the study. Blood pressure (BP), biochemical parameters, CVC, LVH and LV geometry were determined. Results: Most patients were normotensive. CVC of the mitral and aortic valves and of both valves were noted in 22, 23 and 15% of patients, respectively. Patients with CVC had significantly higher diastolic BP (p = 0.023), cardiothoracic index (CTI; p = 0.037) and LV mass index (LVMI; p = 0.002). LVH, noted overall in 44% of cases, was present in 62 and 36% of the patients with and without CVC, respectively (p = 0.028). Of the whole group, only 50.6% had normal LV geometry. LVH was associated with lower serum albumin (p = 0.002), higher CTI (p = 0.027) and more frequent CVC (p = 0.028). LVMI was greater in patients with CVC (p = 0.002). Conclusion: Strict salt restriction and the achievement of ideal dry weight result in normotension in PD patients. CVC is associated with LVH, both of which are lower in normotensive patients.
Summary
Background
The aim of this study is to examine the relationship among the changes in activities of paraoxonase (PON), arylesterase (ARE) and homocysteine thiolactonase (HTLase) enzyme having antioxidant properties and the development of diabetic nephropathy (DN), one of the most common complications of diabetes.
Methods
Normoalbuminuric type-2 diabetic patients (Group II, n=100), microalbuminuric type 2 diabetic patients (Group III, n=100) and the control group (Group I, n=100) were included in the study. The age and gender of the patient groups matched with the age and gender of the control group. HTLase, PON and ARE enzyme activities were measured by the spectrophotometric method using a g-thiobutyrinolactone, paraoxon, and phenylacetate substrates respectively. In this study, an autoanalyzer application was developed in order to measure HTLase enzyme activity for the first time.
Results
Serum HTLase, ARE and PON activities of Group III and Group II were significantly low compared to HTLase, ARE and PON results of Group I (p<0.05).
Conclusions
Based on our results, PON, ARE and HTLase enzyme activities were found to be decreased due to the increase in the degree of DN.
