Secondly, rhGH seemed to exhibit a more modest effect on fat distribution in patients without HALS. Thirdly, rhGH is relatively expensive; at a dose of 0.7 mg/day the cost is approximately 40 EUR/day or 15 000 EUR/yr. Finally, two of 28 patients in the GH group withdrew from the study because of arthralgias and as many as half of the

patients in the GH group experienced joint pain during the course of the study, compared with only 17% in the placebo group. However, arthralgias occurred almost exclusively in the first 1–2 months of the study period, and only one patient experienced joint pain during all 40 weeks of the study period. Except for arthralgias, the physiological rhGH dose regimen used in this study was accompanied by relatively few AEs, increasing the clinical relevance of a possible positive effect on fat distribution. Follow-up after treatment interruption was not planned in advance; however, we are currently buy CP-868596 examining whether patients maintain the improvement in fat distribution after stopping rhGH. In this context, we do not believe that our results motivate the rate of rhGH as a treatment option in unselected

HIV-infected patients. Patients with HALS including abdominal fat accumulation benefited more than non-HALS patients from rhGH therapy, and their already existing impairment in fat distribution worsened in the absence of rhGH treatment, as indicated by the net treatment effect of rhGH therapy showing a 25% reduction in VAT and a 19% reduction in trunk fat when only HALS patients were considered. This group of patients APO866 in vitro could represent a clinically relevant population for future high-physiological-dose rhGH treatment. In summary, it was demonstrated that a high-physiological-dose rhGH treatment

regimen of 40-week duration in HIV-infected patients on HAART was associated with favourable changes in fat distribution. Moreover, the rhGH regimen was well tolerated and did not impair glucose tolerance in these patients. The findings are promising for the future development of treatment options in HIV-infected patients suffering from morphological and metabolic abnormalities associated with HAART.
