Chronic subclinical hyperthyroidism was associated with improved endothelial function and lipid profile, while haemostatic and inflammatory parameters were impaired. The two opposite mechanisms may well compensate for each other at the level of the vessel wall.

The authors studied dyslipidaemia and "obesity" in 137 patients (87 males and 50 females) following cadaver renal transplantation with regard to the applied immunosuppressive treatment and the patients' hypertension. The most extreme dyslipidaemic values, the highest levels of total cholesterol, LDL and Apo were found 6 to 18 months after successful transplantation; these values were significantly higher in women than in men. While in the dialysis programme only 21.89% of the patients had BMI values higher than 25.1 kg/m2, after transplantation their proportion was 36.49%. In addition to hyperlipidaemia, hyperuricaemia was encountered in 39.42%, erythrocytosis in 8.76% and diabetes mellitus in 9.48%, respectively. In the group of patients treated only with Cyclosporine-A the incidence of hyperlipidaemia and hypertension was significantly lower than in those receiving a combination of either corticosteroids and Cyclosporine-A or corticosteroids, Cyclosporine-A and azathioprine. There was a close relationship between the unfavourable tendency of obesity and the measured hyperlipidaemia. On the other hand, the extent of proteinuria did not always have a positive correlation with the increase of BMI and body weight, the severity of hypertension and hyperlipidaemia. The authors emphasize the importance of a systematic control of the lipid levels, the significance of a diet with an adequate carbohydrate and lipid content, and the necessity of avoiding obesity by selecting the optimal immunosuppressive treatment.
