ABSTRACT: Therapy with either angiotensin converting enzyme inhibitors and angiotensin receptor blockers (ACEI/ARB) or thiazolidinediones (TZD) is associated with dose-dependent decrements in hematocrit and hemoglobin levels. We aimed to investigate the impact of the coadministration of TZD and ACEI/ARB on hematocrit and hemoglobin values in uncomplicated patients with type 2 diabetes mellitus and normal serum creatinine.Data from patients with type 2 diabetes currently followed, were reviewed and patients treated with ACEI/ARB and/or TZD were identified. For the purpose of this study the following 4 groups of 30 stable non-anemic diabetic patients each matched for age, gender, and BMI were formed. Group ACEI/ARB included patients on ACEI/ARB without TZD, group TZD included patients on TZD and antihypertensive agents other than ACEI/ARB, group ACEI/ARB/TZD consisted of patients on combined therapy with ACEI/ARB and TZD and the control group C included patients never exposed to ACEI/ARB or TZD. Clinical and laboratory data were collected prior to initiation of treatment and after 6 months.Neither hematocrit nor hemoglobin showed any significant change from baseline at the end of the study in group C. In both group ACEI/ARB and group TZD a small, but statistically significant reduction in hematocrit (~ 1% point) and hemoglobin levels (~ 0.3 g/dl) was seen. A greater statistically and clinically important reduction in hematocrit (~ 3% points) and hemoglobin (~ 1 g/dl) levels was observed in group ACEI/ARB/TZD. Furthermore, incident anemia at the end reached 7% in group TZD and 23% in group ACEI/ARB/TZD.Coadministration of RAS inhibitors and PPAR-γ agonists should be considered in the differential diagnosis of hematocrit lowering and anemia in uncomplicated type 2 diabetic patients with normal serum creatinine. Further studies are required to clarify the mechanism(s), the cardiovascular consequences and the cost utility of anemia workup in such patients.Experimental and Clinical Endocrinology & Diabetes 03/2012; 120(7):416-9. · 1.56 Impact Factor

ABSTRACT: Diabetes mellitus (DM) is recognised as a major health problem. Ninety-nine percent of diabetics suffer from type 2 DM and 10% from type 1 and other types of DM. The number of diabetic patients worldwide is expected to reach 380 millions over the next 15 years. The duration of diabetes is an important factor in the pathogenesis of complications, but other factors frequently coexisting with type 2 DM, such as hypertension, obesity and dyslipidaemia, also contribute to the development of diabetic angiopathy. Microvascular complications include retinopathy, nephropathy and neuropathy. Macroangiopathy mainly affects coronary arteries, carotid arteries and arteries of the lower extremities. Eighty percent of deaths in the diabetic population result from cardiovascular incidents. DM is considered an equivalent of coronary heart disease (CHD). Stroke and peripheral artery disease (PAD) are other main manifestations of diabetic macroangiopathy. Diabetic cardiomyopathy (DC) represents another chronic complication that occurs independently of CHD and hypertension. The greater susceptibility of diabetic patients to infections completes the spectrum of the main consequences of DM. The serious complications of DM make it essential for physicians to be aware of the screening guidelines, allowing for earlier patient diagnosis and treatment.Insights into imaging. 04/2011; 2(2):193-203.
