Sleep architecture in Sheehan's syndrome before and 6 months after growth hormone replacement therapy

Objective: To characterize the steep parameters in patients with growth hormone (GH) deficiency in Sheehan's syndrome adults and to assess the effects of 6-month GH replacement therapy (GHRT). Methods: Twenty-two women with Sheehan's syndrome, (mean age; 49.1 +/- 2.2 years), and 12 women with similar age (mean age; 51.3 +/- 3.8 years) and body mass index as control subjects were included in the study. Under baseline conditions, women received adequate hormone replacement therapy for all hormonal deficiencies other than GH. Twelve patients received recombinant GH (Genotropin; Pfizer Stockholm, Sweden) (treatment group) and eight patients received placebo (placebo group) for 6 months. Two patients had only baseline evaluation and were not followed up prospectively. Two polysomnography (PSG) recordings were performed on the patients group, one in the baseline period and the other at the sixth month of treatment (either GH or placebo). Control group had only baseline PSG. Results: GH deficient females with Sheehan's syndrome have more NREM (95.9 +/- 1.5% and 88.6 +/- 0.9%, respectively; p < 0.05), particularly in stage 4 steep (11.4 +/- 1.9% and 4.9 +/- 1.6, respectively; p < 0.05), less REM steep (4.2 +/- 1.5% and 11.4 +/- 0.9, respectively; p < 0.05) and also less steep efficiency (69.7 +/- 3.4% and 81.1 +/- 2.8%, respectively; p < 0.05) when compared to healthy controls. After 6 months of GHRT there was no significant difference in steep parameters. Conclusion: GH deficiency has steep disturbing effects on Sheehan's syndrome patients under baseline conditions.
