Reduced Bone Mineral Density and Serum C-Telopeptide Concentration in HIV-infected Patients in Cipto Mangunkusumo Hospital
To evaluate BDM and bone resorption marker in HIV-infected patients in Cipto Mangunkusumo Hospital, Jakarta. A cross-sectional study was performed between February and May 2008 in adult HIV-infected patients who had not been treated with antiretrovirals. BMD was measured at the lumbar spine by dual energy X-ray obsorptiometry (DEXA) bone densitometer (Lumar Prodigy, GE Medical System, USA), Whereas CTX (C-terminal telopeptide) was measured by an outomated analyzer (Elecsys 2010. Roche Diagnostics GmbH, Mannheim, Germany) using the b-Crosslaps serum reagents. Fourty-two patients were include, comprising 31 (73.8%) men and 11 (26.2%) women. Patients median age was 28 years, ranging from 22 to 39 years old. The peak age group was 26-30 years old Low BMD (osteopenia) was found in 11 (26.2%) of patients. Mean serum CTX level was significantly correlated with BMD (r=0.446: p+0.003). Patients with low CD4 count and low BMI tended to have higher serum CTX. HIV-infected, treatment-naïve patients possess a significant risk for reduced BMD due to increase bone resorption activity. Faurther studies are needed to evaluate the association of disease sverity and bone resorption markers.
