Abstract

AIM: The aim of this study was to investigate the effects of bromocriptin treatment on leptin levels in patients with hyperprolactinemia. MATERIALS AND METHODS: Twenty female patients with prolactinoma (4 with macroadenoma and 16 with microadenoma) are included in the study. 20 age-, body mass index (BMI)-, and waist/hip (W/H) ratio-matched(34.6±4.8 vs.36.5±4.4; 27.0±5.8 vs 25.9±5.9 kg/m2; and, 0.91±0.16 vs. 0.89±0.16, respectively; p>0.05 in all) normoprolactinemic female subjects formed the control group. None of he patients had ever used any kind of treatment modality for hyperprolactinemia. Bromocriptin treatment is started at 5 mg/ day, and the dose is increased 5 mg weekly up to 20 mg/day. Serum prolactin and leptin levels are measured before and at the eighth week of treatment. RESULTS: Pretreatment serum prolactin levels were higher in the patient group, but leptin levels were similar. With treatment there occurred significant decreases in prolactin and leptin levels, and BMI and W/H ratio in the patient group. CONCLUSION: Bromocriptin treatment resulted in parallel decreases in leptin and prolactin levels in patients with prolactinoma. This decline may be due to decreased leptin stimulatory effect of prolactin on fat cells.

Özet

AMAÇ: Bu çalışmada hiperprolaktinemili hastalarda bromokriptin tedavisinin leptin düzeyine olan etkisini araştırmayı amaçladık. GEREÇ VE YÖNTEM: Çalışmaya prolaktinoma tanısı konulan ve dördünde makroadenom, onaltısında ise mikroadenom mevcut olan toplam 20 kadın hasta alındı. Hasta grubu ile yaş, beden kitle indeksi(BKİ) ve bel kalça oranı(W/H) benzer olan (sırasıyla 34.6±4.8'e karşı 36.5±4.4, p>0.05; 27.0±5.8'e karşı 25.9±5.9 kg/m2, p>0.05; 0.91±0.16'e karşı 0.89±0.16; p>0.05 ) normoprolaktinemik 20 kadın ise kontrol grubunu oluşturdu. Hasta grubu daha önceden hiperprolaktinemi nedeni ile medikasyon uygulanmamış olan hastalardan oluşuyordu. Bromokriptin tedavisi 5 mgr/gün dozunda başlanılıp, haftada 5 mg artışlar ile 20 mg'a çıkıldı. Tedavi öncesi ve tedavinin 8. haftasında serum prolaktin ve leptin düzeyleri için örnekler alındı. SONUÇLAR: Hasta grubunda tedavi öncesi prolaktin düzeyleri kontrol grubuna göre anlamlı olarak yüksek iken, leptin düzeyinde fark yoktu. Tedavi sonrasında ise hasta grubunda prolaktin, leptin, beden kitle indeksi ve bel kalça oranlarında istatistiksel olarak anlamlı azalma tesbit ettik. KARAR: Sonuç olarak prolaktinomalı kadın hastalarda bromokriptin tedavisi sonrasında leptin düzeylerinin prolaktin düzeylerine paralel bir şekilde azaldığını gösterdik. Bu azalmadan prolaktinin yağ hücreleri üzerine leptin salgılatıcı uyarısının zayıflaması sorumlu olabilir.
