Nandrolone decanoate is a good alternative for the treatment of anemia in elderly male patients on hemodialysis.

OBJECTIVE: To assess the efficiency of nandrolone decanoate (ND) in the control of anemia in elderly male patients on hemodialysis (HD), and to determine its influence on nutritional parameters. DESIGN: A prospective 6-month study with randomization of patients on recombinant human erythropoietin (rHuEPO) therapy into two groups. Group A: rHuEPO was stopped before starting treatment with ND. Group E: rHuEPO was continued. SETTING: Renal unit, tertiary-care center. PATIENTS: 14 male patients in Group A and 19 patients, 12 males and 7 females, in Group E. INTERVENTIONS: In Group A rHuEPO was stopped and ND 200 mg/I.M. weekly was given over six months. RESULTS: The increase in hemoglobin and hematocrit levels was progressive with ND, and significant differences (p < 0.003) were evident after six months (9.6 +/- 1.0 vs 11.0 +/- 1.4 and 28.9 +/- 4.7 vs 33.0 +/- 4.7, respectively), which remained unmodified in Group E. Group A showed a significant increase in serum creatinine, total protein, transferrin and anthropometric parameters. These parameters remained stable and even presented a tendency to decrease in Group E. There was a significant rise in the concentration of triglycerides and a significant decrease in both HDL-cholesterol and apolipoprotein A-1 in Group A. However, lipoprotein (a) decreased significantly. No significant changes were detected in Group E. CONCLUSIONS: The use of ND would allow us an acceptable treatment of anemia as well as a better nutritional condition in elderly male patients on dialysis.

[Primary empty sella turcica: clinical aspects and hormonal study of 15 cases].

The goal pursued has been to analyze clinical observations and hormonal studies of patients with empty sella turcica (EST), in order to review this disorder and determine if it can be considered a real syndrome. Fifteen patients with EST (3 men and 12 women) and mean age of 45.6 +/- 17.9 years have been prospectively studied. In the hypothalamus-hypophysis study, reserves of thyrotropin (TSH), prolactin (PRL), gonadotropins (FSH and LH), growth hormone (GH), adrenocorticotropin (ACTH) and cortisol were assessed. In addition, thyroid hormones and, for men, testosterone, were determined. The pathogenic mechanism was explained in two cases (13.3%). We registered headache in 10 patients, obesity in 8, arterial hypertension in 2 and diabetes mellitus in 2. Multiparity antecedent was found in 2 cases. The hormonal study was abnormal in two cases (40%). Most common abnormalities were hyperprolactinemia (3 cases), deficit of gonadotropins (3 cases), without coexisting both of them in any case, and deficit of GH (2 cases). EST is frequently associated with endocrine disfunction, although clinical implications are rare. The absence of common clinical manifestations in most cases questions the EST as a real syndrome.
