does interferon therapy prevent from osteoporosis?
GROUND: Our aim was to determinate bone mineral density (BMD), levels of biochemical markers and cytokines in children with chronic hepatitis B treated with interferon (IFN)-alpha and to investigate effect of IFN-alpha therapy on these variables. To the best of our knowledge, this is first study carried out about BMD and cytokine levels in pediatric patients with chronic hepatitis B treated with IFN-alpha. METHODS: BMD, levels of parathyroid hormone (PTH), osteocalcin, C-terminal cross-linking telopeptide of type I collagen (CTX), calcium, alkaline phosphates (ALP), cytokines as TNF-alpha, interleukin (IL)-1beta, IL-2r, IL-6, and IL-8 were studied in 54 children with chronic hepatitis B (4-15 years old) treated with interferon alone (n = 19) or in combination with lamivudine (n = 35) for six months and as controls in 50 age-matched healthy children. RESULTS: There was no significant difference in respect to serum IL-1beta, TNF-alpha and osteocalcin levels while serum IL-2r (p = 0.002),
