Abstract

Hydroxy methylglutaryl coenzyme A reductase inhibitors (statins) have been shown to have effects on bone metabolism in laboratory studies. While early clinic studies have showed lower risk for osteoporotic fractures among statin users than nonusers, subsequent studies have found mixed results. The purpose of this study was to investigate the effects of statins on bone mineral density (BMD) and bone metabolism. Thirty-five consecutive postmenopausal hypercholeste-rolemic women who were treated for at least last 6 months with statins were included in the study. Seventy-five normocholesterolemic age-matched postmenopausal women were in the control group. Subjects with a history of any diseases and used drugs that may affect calcium or bone metabolism were excluded from the study. Age, associated illness, years since menopause, and body mass index (BMI) were obtained from all the patients including the control group. Besides, serum calcium, phosphate, alkaline phosphates, parathyroid hormone, 25 hydroxy D3, osteocalcin, and urinary calcium excretion were measured. BMD was measured by using dual-energy x-ray absorptiometry (DEXA) at femoral neck and 3rd lomber spine. Mean duration of statin use was 28.17+21.17 months. BMI was found to be statistically higher in statin users than nonusers (27.47±3.67kg/m2 and 25.46±3.91 kg/m2, respectively). The markers of bone metabolism used in the study were found to be similar between the groups. BMD was not different in statin users and no¬nusers at femoral neck and lomber spine. As conclusion, statin use did not affect BMD and bone metabolism in this study. In our opinion large randomised, controlled, prospective clinical trials are needed to accurately determine the role of statins in the treatment of osteoporosis.

Özet

Hidroksi metilglutaril koenzim A redükfoz inhibitörierinin (statinler) kemik metabolizması üzerindeki etkileri laboratuvar çalışmalarında gösterilmiştir. Daha erken dönemde yapılan klinik araştırmalarda statin kullananlarda kullanmayanlara kıyasla osteoporotik fraktür riskinin daha düşük olduğu bildirilirken, diğer çalışma sonuçları çelişkilidir. Bu araştırmanın amacı statinlerin kemik mineral yoğunluğu (KMY) ve kemik metabolizması üzerindeki etkilerini araştırmaktır. Çalışmaya en az son 6 aydır statin kullanan 35 postme-nopozal hiperkolesterolemik kadın hasta alındı. Yaş benzer 75 normokolesterolemik postmenopozal kadın ile de kontrol grubu oluşturuldu. Kemik veya kalsiyum metabolizmasına etkili hastalığı ve ilaç kullanım öyküsü olanlar çalışmaya alınmadı. Kontrol grubu da dahil olmak üzere tüm hastalarda yaş, eşlik eden hastalıklar, menopoz süresi ve vücut kitle indeksi (VKİ) kaydedildi. Ayrıca serum kalsiyum, fosfor, alkalen fosfataz, paratiroid horman, 25 hidroksi D3, osteokalsin düzeyleri ve idrar kalsiyum atılımları ölçüldü. KMY ise dual-enerjili x-ray absorpsiyometre (DE-XA) ile femur boynu ve 3. lomber vertebradan ölçüldü. Hastaların ortalama statin kullanım. süresi 28.17 ± 21.1 7 aydı. Statin kullanan grupta VKİ'nin kullanmayanlardan anlamlı derecede daha yüksek olduğu tespit edildi (sırasıyla, 27.47±3.67kg/m2 ve 25.46± 3.91 kg/m2). Çalışmada kullanılan kemik metabolizması belirteçleri açısından ise gruplar benzerdi. Statin kullanan ve kullanmayanlar arasında femur boynu ve lomber vertebra KMY açısmdan farklılık tespit edilmedi. Sonuç olarak bu araştırmada statin kullanımın KMY ve kemik metabolizması üzerinde etkili olmadığı belirlenmiştir. Statinlerin osteoporoz tedavisindeki yerinin daha net olarak aydınlatılabilmesi için geniş vaka sayılı, randomize, kontrollü, prospektif nitelikte klinik araştırmaların yapılması gerektiği düşüncesindeyiz.
