Adrenal cortex function in asthmatic patients following the discontinuation of chronic therapy with systemic glucocorticosteroids.

OBJECTIVE: To estimate the time it takes for adrenal cortex function in asthmatic patients to return to normal after discontinuation of chronic therapy with systemic glucocorticosteroids (GCs) and to assess the relationship between the duration of the disease, chronic therapy, and the return of the normal adrenal cortex functioning. MATERIALS AND METHODS: The study involved 58 asthmatic patients and 31 healthy volunteers (aged 20-69 years). Adrenal cortex function was evaluated with the Synacthen short test, and determining serum and urinary free cortisol levels after 1, 3, 6, 12, 18, and 21 months following the discontinuation of systemic therapy with GCs. RESULTS: A decreased adrenal reserve was observed 1 month after withdrawal of GCs in 50% of the chronically treated patients. Adrenal cortex function returned to normal in 55% of patients within 6 months, in 24% within 12 months, and in 14% within 15 months of discontinuation of systemic GCs administration. A significant positive correlation between the time taken for return to normal adrenal cortex function and duration of the disease and of GCs therapy was found. CONCLUSIONS: Symptoms of adrenal failure may develop in about 50% of asthmatic patients. In the majority of patients treated long term with systemic GCs, adrenal cortex function returns to normal within 6 months following discontinuation of GCs. The time of such return depends on the duration of the disease and of therapy with systemic GCs.

Suramin: an anticancer drug with a unique mechanism of action.

We administered suramin, an anti-parasitic drug and reverse transcriptase inhibitor, to 15 patients with metastatic cancer. This compound is known to inhibit the binding of growth factors (eg, epidermal growth factor [EGF], platelet-derived growth factor [PDGF], tumor growth factor-beta [TGF-beta]) to their receptors and thus antagonize the ability of these factors to stimulate growth of tumor cells in vitro. There were no complete responses (CRs), four partial responses (PRs) (two of ten adrenal cortex, one of four renal, one of one adult T-cell leukemia-lymphoma [HTLV-1]), and two minimal responses (MRs) (two of ten adrenal cortex). Toxicity included proteinuria (14 patients), reversible liver function test abnormalities (eight), vortex keratopathy (five), adrenal insufficiency (three), coagulopathy secondary to increased circulating levels of glycosaminoglycans (11), and one case of a reversible acute demyelinating polyneuropathy resembling the Guillain-Barrè syndrome. We conclude that suramin is an active agent in the treatment of metastatic cancer, and further work is necessary to define its scope.

[Functional state of the adrenal cortex in experimental animals administered leyorin and its sodium salt perorally].

The effect of oral levorin and its sodium salt on the function of the adrenal cortex was studied experimentally on albino rats. The functional activity of the adrenal cortex was tested by the content of corticosterone in the peripheral blood determined fluorometrically. The results showed that levorin in a dose of 300 000 Unit/kg and its sodium salt in doses of 300 000 and 1 200 000 Units/kg used orally induced at definite periods of their administration a decrease in the corticosterone blood levels. At the same time a decrease in the weight coefficients of the thymus and prostate was observed.
