[Diabetic retinopathy (DR) is a leading cause of visual impairment worldwide. It affects nearly half of patients with diabetes and its severity increases with the progress of diabetes. Glycotoxicity, lipotoxicity and hypertension are the main risk factors for the development of DR. The control of glucose homeostasis and blood pressure are the main noninvasive approaches that might have a role in the treatment of this condition. On the basis of new studies, RAS inhibitors and fenofibrate are promising candidates that can be used to retard DR progression and/or induce its regression. Two large-scale studies (FIELD, ACCORD Eye) have demonstrated that fenofibrate therapy significantly reduces the need for laser treatment of DR. The efficiency of this therapy, which is independent of lipid changes, is primarily attributable to the PPAR-α agonist activity of fenofibrates. According to guidelines that discuss the new therapeutic approaches of DR, fibrate therapy is a promising new option for preventing the progression of DR.]

[Bone mineral density and diabetes mellitus - First results]

TÕKE Judit, TAMÁS GYULA, STELLA Péter, NAGY Erzsébet, NÁDASDI Ágnes, VARGA Piroska, KERÉNYI ZSUZSA

[INTRODUCTION - Data on bone mineral density (BMD) in diabetes mellitus are contradictory in the literature. Early studies described a decreased bone mineral density in type 1 diabetes mellitus (T1DM), but recent studies report no osteopenia in T1DM.The BMD may depend on the quality of treatment for diabetes mellitus and on the presence of chronic complications. In type 2 diabetes mellitus (T2DM) the BMD is not decreased, occasionally it can even be increased. PATIENTS AND METHODS - Bone mineral density was measured in 122 regularly controlled diabetic patients (T1DM: n=73, mean age: 43.6±11.1 years,T2DM: n=49, mean age: 61.8±9.8 years) by dual energy X-ray absorptiometry at the lumbar spine and at the femur. Results were compared to those of 40 metabolically healthy control persons with a mean age of 47.5±11.9 years.The patients’ carbohydrate metabolism was assessed by the average HbA1c level of the last three years.These values were 7.9±1.4 % in T1DM, and 7.5±1.7 % in T2DM. BMDs were classified based on the T-score and Z-score using the WHO criteria. RESULTS - There was no significant difference in T1DM or in T2DM compared to the reference group in the prevalence of either osteoporosis or of osteoporosis and osteopenia combined. CONCLUSION - BMD was not found to be decreased in patients with well-controlled metabolism compared to healthy controls.]

[Summary of guidelines for American, European and International Companies in diabetes mellitus type 2 associated with hypertonia]

KÉKES Ede, DOLGOS Szilveszter

[The importance of hypertension in type 2 diabetes mellitus, the method of continuous blood pressure control and patient’s careas well as the forms of non-drug and drug therapy have been disclosed by presenting therapeutical recommendations from American, European scientific societies and international organizations. It has been established that the principles of care and treatment of hypertonia have basically remained unchanged in diabetes all over the world, despite the recent widespread debate over the interpretation of normal blood pressure and the consideration of the benefits of intensive or standard treatment.]

[The prevalence of type 2 diabetes mellitus in the Hungarian population with hypertension]

KÉKES Ede, PÁL László, SCHANBERG Zsolt, KISS István

[Authors had found diabetes mellitus type 2 in 30% of 38 886 hypertensive patients (stadium I-III). Diabetes was more frequent in case of women under 30 years. Subsequently all age groups (from 40 to 80 years) incidence was more frequently (p<0.01-0.001) in men, above 80 years again a higher ratio was in women. Presence of diabetes was correlated to rate of BMI value and systolic, diastolic pressure as well. In women - above 140 mmHg systolic pressure - the elevation was exponential. We have found a significant correlation between fasting glucose and waist. Reaching the target blood pressure is not a simply task in hypertensive patients with diabetes. The 140/90 mmHg was reached in 34.2%, 90 mmHg diastolic blood pressure in 62.3%, but the required 80 mmHg only in 16.4% of cases. Achieve the target value was quite different in the different region of our country. The major cardiovascular complications (stroke, renal disease, myocardial infarction, peripheral artery disease) have suffered a higher rate in the hypertensives with diabetes compered to hypertensives without diabetes.]

[Insulin analogues and pregnancy]

TAMÁS GYULA, KERÉNYI ZSUZSA

[Near-normoglycaemic metabolic control in pregnant women with diabetes - started before conception in pregestational diabetes - decreases the frequency of maternal and foetal complications. Such control can be achieved by using optimalised systems of insulin therapy. A number of (ultra)rapid and long-acting insulin analogues became available during the last decade, which - on the basis of theoretical considerations - might be used to maintain normoglycaemia. Summarising the data available today, the use of rapid insulin analogues (lispro, aspart) seem to be effective and safe during pregnancy. Some questions arise, however, about their modes of application. The use of long-acting insulin analogues in pregnancy is currently not indicated. Further trials are needed to prove their efficacy and safety in diabetic pregnancy.]

[Investigation of skin microcirculation in diabetes mellitus by laser Doppler flowmetry]

KOLOSSVÁRY Endre, FARKAS Katalin, STELLA Péter, FARSANG Csaba

[The prognosis of patients with diabetes mellitus is mainly influenced by vascular complications which is partly due to the deterioration of the microcirculation. Laser Doppler flowmetry is a suitable method to investigate the complex disturbance that characteristic for diabetic microcirculation. This review gives a summary of the anatomical, physiological and theoretical backgrounds and the possibilities in diagnosis given by Laser Doppler flowmetry.]
