Abstract

Aim: The aim of this study was to determine whether circulating levels of insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP-3) were associated with bone mineral density (BMD) and bone turnover markers in middle aged Turkish males. Patients and Methods: At the beginning, a total of 160 Turkish men aged between 35 and 65 years were included to this study. The final sample comprised of 112 men because 48 men were excluded from the study. BMD of the spine and the hip was measured with dual energy x-ray absorptiometry. After an overnight fasting, serum IGF-1, IGFBP-3, intact parathyroid hormone, 25-hydroxy vitamin D, osteocalcin, C-terminal telopeptide, calcium, phosphorous and alkaline phosphatase levels were measured. Urinary concentrations of calcium, phosphorous and creatinine were also estimated.Results: Twenty-one men (18.8%) had a bone mineral density of ≤ -2.5 SD (T score). There was a significant difference in IGF-1 levels between men with normal BMD and men with reduced BMD (132.5 ± 38.1 and 116.1 ± 40.6 respectively and p: 0.04). Serum IGF-1 levels were positively correlated with BMD of the lumbar spine (r: 0.28, p:0.006), but there was no correlation between IGFBP-3 and BMD of any sites tested. IGF-1, IGFBP-3 and BMD were not correlated with bone turnover markers except serum alkaline phosphatase level. Conclusion: Serum IGF-1 levels were lower in men with reduced BMD and positively correlated with BMD of the lumbar spine. Neither IGF-1 nor IGFBP-3 was correlated with bone turnover markers. Further studies of these factors in skeletal cells are needed to explain their role in the pathophysiology of idiopathic male osteoporosis. (From the World of Osteoporosis 2007;13:37-43)

Özet

Amaç: Bu çalışmanın amacı orta yaşlı Türk erkeklerinde serum insulin benzeri büyüme faktörü-1 (IGF-1) ve insulin benzeri büyüme faktörü bağlayıcı protein-3 (IGFBP-3)’ün kemik mineral yoğunluğu ve kemik yapım yıkım belirteçleri ile ilişkili olup olmadığını göstermekti. Hastalar ve Yöntem: Başlangıçta bu çalışmaya 35 ile 65 yaşları arasında 160 Türk erkeği dahil edildi. Daha sonra 48 hasta çalışma dışı bırakıldığı için son örneklem 112 erkeği içerdi. Omurga ve kalçanın kemik mineral yoğunluğu (KMY) dual enerji x-ray absorptiometri ile ölçüldü. Bir gecelik açlık sonrası, serum IGF-1, IGFBP-3, intakt parathormon, 25-OH vitamin D, osteokalsin, C-terminal telopeptid, kalsiyum, fosfor, ve alkalen fosfataz seviyeleri ölçüldü. Kalsiyum, fosfor ve kreatininnin idrar konsantrasyonları da tesbit edildi. Bulgular: Yirmi bir erkekde (% 18.8) kemik mineral yoğunluğu T skoru -2.5 SD’a eşit veya altında idi. Normal ve azalmış KMY’si olan hastalar arasında IGF-1 düzeylerinde anlamlı farklılık vardı (sırasıyla 132.5 ± 38.1 ve 116.1 ± 40.6, p: 0.04). Serum IGF-1 düzeyleri lomber omurganın KMY’si ile pozitif korele idi. Fakat, IGFBP-3 ve test edilen yerlerin hiçbirinin KMY’si arasında korelasyon yoktu. IGF-1, IGFBP-3 ve KMY serum alkalen fosfatazı hariç kemik yapım yıkım belirteçleri korele değildi. Sonuçlar: Serum IGF-1 seviyeleri KMY’si azalmış olan erkelerde daha düşüktü ve lomber omurganın KMY’si ile pozitif olarak korele idi. Ne IGF-1 ne de IGFBP-3 kemik yapım yıkım belirteçleri ile korele değildi. İskelet hücrelerindeki bu faktörlerin, idiopatik erkek osteoporozunun patofizyolojisindeki rolünü açıklamak için ek çalışmalara gereksinim vardır. (Osteoporoz Dünyasından 2007;13:37-43)
