RESUMEN
To establish the possible relationship between acute myocardial infarction (AMI) and dehydroepiandrosterone-sulfate (DHEA-S) in a group of 15 patients with AMI, blood levels of DHEA-S and certain lipids (total cholesterol, LDL-cholesterol, HDL-cholesterol and triglycerides) were determined at admission in the hospital and after 10 days. As controls a group of healthy individuals or with minor diseases, and a group of 24 severely ill non-cardioischaemic patients have been studied. DHEA-S and HDL-cholesterol levels have been found significantly lowered both in patients with AMI (at 10th day) as well as in the severely ill non-cardioischaemic patients, in comparison with the healthy volunteers group. We conclude, then, than the lowering in DHEA-S and HDL-cholesterol seems not to be specifically relates with AMI but has a certain relationship with severe disorders in general.

The plasmatic concentration of beta-endorphins and ACTH were measured in 31 alcoholic patients and in a control group (N = 16), to test the possible relation between chronic alcohol intake and propiomelanocortin production. There were found a decrease of beta-endorphins plasmatic levels in chronic alcoholic group, apart of clinical manifestations or abstinence period (one month maximum). This decrease can be cause by the chronic alcohol intake, and can be mediated by the tetrahydroisoquinolines (TIQs) or otherwise be the cause and not the consequence of alcoholism. The global plasmatic levels of ACTH were decreased but it was significant in the subgroup of alcoholics with liver disfunction, mental illness and those who carry on drinking.

This study tries to evaluate the interrelationship amongst certain corticoadrenal hormones (Dehydroepiandrosterones-Sulphate (DHEA-S), progesterone, 17-OH progesterone and cortisol) in male patients with severe organic processes (24 chronic and 22 acutely ill) and comparing them with a control group of 15 healthy male subjects or suffering mild processes. Corticoadrenal hormone behaviour in the presence of a severe disease show marked differences between the androgenic and the glucocorticoid pathways. While DHE-S shows a significant decrease in severe disease, independently of the underlying disease (acute or chronic), the contrary occurs with the glucocorticoid pathway, in which cortisol and specially its precursors, progesterone and 17-OH-progesterone, predominantly present in the acute situation, normal or significantly increased levels. These differences between the two adrenal pathways suggest that apart from ACTH there must be another regulatory mechanism of the androgenic pathway which may facilitate the androgenic adaptation to the situation of severe disease.
