ÖZET
Amaç: Postmenopozal osteoporozu olan kadınlarda tek baºına tibolon (T), alendronat (A) ile T+A tedavisinin kemik mineral yoğunluğu (KMD) ve kemik turnover belirteçleri üzerindeki etkilerinin kıyaslanması. Gereç ve Yöntemler: Çalıºmaya alınan 60 osteoporozlu kadın 3 gruba ayrıldı. Bir yıl boyunca 1. gruba alendronat 10 mg/gün, 2. gruba tibolon 2.5 mg/gün (T), 3. gruba T + A verildi. Tüm gruplara 1500 mg/gün kalsiyum verildi. Tedavi öncesi ve sonrası KMD ve kemik turnover belirteçleri ölçüldü. Bulgular: KMD, T + A alan grupta diğer gruplara göre anlamlı derecede yüksekti. Tek baºına A alanlarda T alanlara göre KMDde daha fazla artıº tespit edildi. Kemik turnover belirteçleri en çok T + A grubu olmak üzere bütün gruplarda anlamlı derecede düºüº gösterdi. Sonuç: Postmenopozal osteoporozlu hastalarda T + A etkili bir tedavi rejimidir. Tek baºına A veya T ikinci seçenek olarak düºünülebilir. Kemik turnoveri yavaºlamıº ileri yaºta hastalarda, gastrointestinal hastalığı olanlarda T tek baºına verilebilir. Te-davi planlanırken hem hastanın hem ülkenin ekonomik durumu ve tedavinin etkinliği göz önünde bulundurulmalıdır.
ABSTRACT
Objective: Aim of this study was to compare the effect of tibolone (T), alendronate (A) and T + A treatment on bone mineral density (BMD) and bone remodelling markers in postmenopausal women with osteoporosis. Material and Methods: 60 women having osteoporosis were enrolled to the study. The patients were divided into 3 groups. Alendronate 10 mg/day was given to the first, tibolone (T) 2.5 mg/day was given to the second, T + A were given to the third group for a year. 1500 mg/day calcium supplementation were given to all groups. BMD and bone remodelling markers were measured be-fore and after the treatment. Results: There was statistically significant increase in BMD in T + A group than the other two. If T and A groups compared, only A was found to be superior than T. Bone remodelling markers were found to be decreased significantly in all groups. Decrease in these markers was most significant in T + A group. Conclusion: T + A is an effective treatment regimen in patients with postmenopausal osteoporosis. Only T or only A treatment can be second choice. In older postmenopausal patients with slower bone turnover and in women with gastrointestinal disorders, only T can be ordered. The economic state of the patient and the country, the effectiveness of the treatment must be considered during planning of treatment regimen.
