[The value of selenotherapy in patients with mucoviscidosis].

In cystic fibrosis (CF) patients the antioxidative-oxidative balance is chronically disturbed. Free radicals were generated by bronchial-pulmonal infection and additional exist a deficiency of antioxidative substances by enteral malabsorption especially vitamin E and selenium. Because selenium is an essential content of glutathione peroxidase, which is acting in cytosol and cell membranes, for the present we tested a selenium therapy (peroral sodium selenite 155 micrograms (Se/m2 BSA/d i. e. 4 micrograms Se/kg/d; 4 fold of recommended supply) in 32 CF patients. After three months of this therapy we have seen positive metabolic (normalized content of plasma-selenium, -glutathione peroxidase), endocrine (enhanced efficacy of thyroid hormones, mild increased IgF-I reduced LDL-chol) and clinical consequences (enhanced left ventricular cardiac output), but in three patients side effects (anorexia, nausea, mild hair loss) were observed. Longtime sodium selenite therapy only with 60 micrograms Se/m2 BSA/d over 1 year, stabilized the favourable influences without side effects. For CF patients therefore we recommend a sodium selenite substitution therapy, the best in combination with vitamin E.

[Euthyroid goiter in puberty--a harmless illness?].

An investigation was carried out in to thyroid hormones (TSH, T3, T4) and lipid parameters (total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride) in 136 adolescents (94 femals, average age 13 years). An iodine deficiency (grade II-II) with respect to the daily urine excretion per 1,73 m2 BSA was found in 75%. With few exceptions the serum levels of TSH and T4 were in the normal range. In 36% of the patients we noticed compensatory elevated T3 levels. Correlations between thyroid hormones TSH, T4, renal iodine excretion and the volume of thyroid glands were not detectable, only T3 showed a dignificant positive correlation to the thyroid gland volume. The average values of lipids in patients were found to be higher than in normals. We consider the changed lipids as a sign of a disturbed efficacy of thyroid hormones. The regional insufficient iodine supply causes goiters and to a high degree the observed hyperchole-sterolemia, too. Our results underline the necessity of a common iodine salt prophylaxis as well as the treatment of "harmless" goiters in puberty.

[Therapy of iodine deficiency goiter in adolescents with iodine or a combination of iodine and levothyroxine with special reference to lipid parameters].

The are various opinions about the optimal therapy of endemic goiter in adolescents. From 106 patients (75 girls) suffering from endemic goiter 50 patients (group A) were treated with 300 micrograms iodine per day and 56 patients (group B) with 100 micrograms iodine plus 100 micrograms levothyroxine per day. Before therapy and after 172 days of therapy on average the thyroid volume, the thyroid hormones (TSH, T3, T4) and the lipidparameters (cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides) were measured. Within the period of treatment the thyroid volume (measured by ultrasound) decreased by 11.3% in group A and by 23% in group B. The iodine deficiency was corrected completely in both groups. However, investigations in both groups proved that patients undergoing combined therapy excrete the iodine administered additionally. Analogously to studies of the intrathyreoidal iodine metabolism it can be concluded that combined therapy on the basis of the dose mentioned above does either not result in an increase in the intrathyreoidal iodine contents or in a minor increase only. Iodine treatment as well as combined treatment cause a decrease in TSH-levels and an increase in T4-levels. The changes are only significant in group B. In the total group the percentage of T3-increases was reduced from 45% to 33% during treatment. The initially elevated plasma concentration of cholesterol, LDL-cholesterol and triglycerides - compared to the control group - decreased significantly in both groups during therapy. Both groups does not differ significantly with respect to the decrease in lipids. It is to be concluded that combination therapy is preferable to iodine therapy with respect to the SD-volume reduction as well as the lipid metabolism. The primary cause of endemic goiter, i.e. the intrathyreoidal iodine deficiency, can presumably not be eliminated by means of the dose of 100 micrograms iodine combined with 100 micrograms LT4.
