Abstract

Objective: Previous studies showed relation between elevated serum leptin levels (SLL) and hypertension. The aim of this study was to evaluate relationship between SLL and left ventricular hypertrophy (LVH) and body mass index (BMI) in obese hypertensive patients. Methods: Eighty patients with newly diagnosed essential hypertension were included in this cross-sectional, case-controlled study. Hypertensive patients were classified as; level-I or level-II according to JNC-VII classification and as normal weighted (18-24.99 kg/m2), over weighted (25-26.99 kg/m2) and obese (27 kg/m2 and above) according to BMI’s. All the patients were evaluated by echocardiography and blood samples were withdrawn for determination SLL. Statistical analysis was performed using Wilcoxon sign rank, Mann Whitney U and Kruskal Wallis tests. Logistic regression analysis was applied for the evaluation of relationship between SLL and clinical variables. Results: Mean levels of arterial blood pressure (ABP) of total 80 patients (36 males and 44 females) was 155±1.1/95.1±0.7 mmHg and the mean age was 48.9±1.3 years. Patients with level I hypertension (n=32) had mean ABP of 149.7±0.5/90.9±0.6 mmHg and with level-II hypertension (n=48) - mean ABP 168.5±1.6/102.9±0.9 mmHg. The mean BMI in normal weighted group (n=26) was 22.7±0.3 kg/m2, over weighted group (n=19)-26.1±0.2 kg/m2 and obese group (n=35)-30.9±0.5 kg/m2. There were no differences in LVH incidence between hypertension level groups and BMI groups (p>0.05). Serum leptin levels were similar in patients with level I and level II hypertension (33.5±2.9 ng/ml and 37.3±3.6ng/ml, respectively, p>0.05). However, leptin levels were higher in obese patients as compared with normal and over weighted patients (40.9±3.2 ng/ml versus 28.5±3.6 ng/ml and 32.8 ± 4.9 ng/ml, p

Özet

Amaç: Hipertansiyon ve şişmanlık günümüzde önemli bir ölüm ve morbidite nedenidir. Daha önce yapılan çalışmalarda hipertansiyon ve şişmanlığın yüksek leptin düzeyleri ile ilişkisi ortaya konulmuştur. Bu çalışmada; hipertansiyon evresi, vücut kitle indeksi (VKİ), sol ventrikül hipertrofisi (SVH) ve leptin düzeyleri arasındaki ilişkinin araştırılması amaçlanmıştır. Yöntemler: Bu enine-kesitsel, vaka-kontrollü çalışmada ilk kez tanı konulan 80 esansiyel hipertansiyon hastası; JNC VII sınıflamasına göre evre 1 ve 2, VKİ’lerine göre (1) 18-24.99 kg/m2 normal, (2) 25-26.99 kg/m2 aşırı kilolu ve (3) ≥27 kg/m2 üzeri şişman olarak sınıflandırılmıştır. Tüm hastalara ekokardiyografik inceleme yapılmış ve leptin düzeyleri ölçülmüştür. İstatistiksel analiz Wilcoxon sign rank, Mann Whitney U ve Kruskal Wallis testleri ile yapıldı. Leptin düzeyi ile klinik değişkenler arasında ilişki lojistik regresyon analiz ile incelendi.Bulgular: Çalışmaya alınan toplam 80 (36E, 44K) hastanın yaş ortalaması 48.9±1.3 olup, ortalama kan basınçları 155±1.1/95.1±0.7 mmHg’dır. Hastaların kan basınçları, Evre-1 grubunda (n=32) 149.7±0.5/90.9±0.6 mmHg ve Evre-2 grubunda (n=48) 168.5±1.6/102.9±0.9 mmHg olarak, ayrıca VKİ’leri, normal kilolu grupta (n=26) 22.7±0.3 kg/m2, aşırı kilolu grupta (n=19) - 26.1±0.2 kg/m2 ve şişman grupta (n=35) - 30.9±0.5 kg/m2 olmak üzere ölçülmüştür. Çalışmada hipertansiyon evreleri ve VKİ grupları arasında SVH açısından anlamlı farklılık bulunamamıştır (p>0.05). Evre-I ve evre -II hipertansiyonlu hastalarda leptin düzeyleri benzer idi (sırası ile 33.5±2.9 ng/ml ve 37.3±3.6ng/ml, p>0.05). Leptin düzeyi şişman grupta normal kilolu ve aşırı kilolu gruplara göre daha yüksek idi (40.9±3.2 ng/ml’ye karşı 28.5±3.6 ng/ml ve 32.8±4.9 ng/ml, p
