Abstract

Objective: Serum lipoprotein(a) [Lp(a)] concentrations, determined in 665 persons in the 2003/04 survey of the Turkish Adult Risk Factor Study, were investigated in regard to distribution, determinants and relationship to cardiovascular risk factors, metabolic syndrome (MS) and coronary heart disease (CHD).Methods: Diagnosis of MS was based on Adult Treatment Panel III criteria, that of CHD on the presence of clinical findings and Minnesota coding of resting electrocardiograms. Metabolic syndrome was observed in 44%, CHD in 14% of the study sample. Behring nephelometry was used for Lp(a) values measurements which were log-transformed for analyses because of skewing. Results: Geometric mean values of Lp(a) in 286 men and 379 women, aged 55.5 ±12.0 years, were 9.46 ±2.90 mg/dL and 10.46 ±3.00 mg/dL (p>0.2), respectively. Apart from a slight correlation with age, Lp(a) exhibited significant positive correlations with apolipoproteins A-I and B, low density lipoprotein-cholesterol (LDL-C) (r =0.15), total cholesterol, high density lipoprotein-cholesterol (HDL-C), systolic blood pressure and log C-reactive protein, and inverse ones with thyroid stimulating hormone (r =-0.25) in men, and log gamma glutamyltransferase in women. Further 10 variables were not significantly correlated in either gender. In linear regression analyses for independent covariates of Lp(a), positive associations were noted with serum total cholesterol and systolic blood pressure, and inverse ones with waist circumference, triglycerides and (only in women) with gamma glutamyltransferase. Logistic regression analyses revealed in men no association with either MS or CHD likelihood. Among women, age-adjusted Lp(a) was associated inversely at a borderline significance with MS, as did levels of Lp(a) >30 mg/dl vs. the remaining sample, controlled for age and MS, display an odds ratio (OR) of 1.62 for prevalent CHD (p=0.20). An OR of 1.92 (p30 mg/dl and LDL-C >150 mg/dl, after controlling for age, MS, smoking status and LDL-C categories.Conclusion: Lipoprotein(a), the variance of which is known to be overwhelmingly due to the apo(a) isoforms, proved to have a significant inverse independent association with a measure of abdominal obesity. Lipoprotein(a) levels appeared not to be associated with risk for MS or CHD among men. In women, however, high Lp(a) levels were accompanied with an environment less prone to MS, and – without attaining significance - tended to be associated with CHD likelihood, independent of age and MS. Further studies are warranted in this area.

Özet

Amaç: TEKHARF Çalışması 2003/04 kohortunda serumda lipoprotein (a)’nın (Lp (a)) belirlendiği 665 kişide dağılımı, kardiyovasküler risk faktörleri, metabolik sendrom (MS) ve koroner kalp hastalığı (KKH) ile ilişkisi incelendi.Yöntemler: Metabolik sendrom tanısı Adult Treatment Panel III kriterlerine, KKH tanısı anamnezde angina varlığı ve 12-derivasyonlu istirahat elektrokradiyogramlarının Minnesota kodlamasına dayanılarak kondu. Örneklemin %44’ünde MS, %14’ünde KKH mevcuttu. Behring nefelometresiyle ölçülen Lp(a) değerleri normal dağılım sergilemediğinden, analizler log-transformasyonla yapıldı. Bulgular: Ortalama yaşı 55.5 ±12.0 yıl olan 286 erkek ve 379 kadında, geometrik ortalama değer sırasıyla 9.46 ±2.90 mg/dL ve 10.46 ±3.00 mg/dL (p>0.2) olup yaşla hafif artıyordu (r =0.08). Başta apolipoprotein A-I ve B ile düşük yoğunluklu lipoprotein kolesterol (LDL-K) (r =0.15) olmak üzere, total kolesterol, yüksek yoğunluklu lipoprotein kolesterol (HDL-K), sistolik kan basıncı ve log C-reaktif protein ile anlamlı doğrusal, erkeklerde tiroid uyarıcı hormon (r =-0.25), kadınlarda log gama glutamiltransferaz ile anlamlı ters korelasyonlar kaydedildi. Log insülin dahil olmak üzere, Lp(a)’nın 10 parametre ile iki cinsiyette de anlamlı ilişkisi görülmedi. Bağımsız belirleyicileri için lineer regresyon analizinde serum total kolesterol ve sistolik kan basıncı ile Lp(a) arasında pozitif, bel çevresi ile her iki cinsiyette, gama glutamiltransferaz ile Lp(a) arasında yalnız kadınlarda ters anlamlı ilişki kaydedildi. Lojistik regresyon analizlerinde erkeklerde Lp(a) ne MS, ne de KKH olasılığı için ilgi çekici bir ilişki gösterdi. Kadınlarda Lp(a) ile MS arasında yaştan bağımsız sınırda anlamlı bir ters ilişki bulunduğu gibi, Lp(a) >30 mg/dl düzeyi yaş ve MS’ten bağımsız şekilde prevalan KKH için (anlamlılığa yaklaşmadıysa da) 1.62’lik odds oranı (OR) sergiledi. Lipoprotein(a) >30 mg/dl ile LDL-K >150 mg/dl birlikteliği tüm erişkinlerde yaş, MS, sigara içimi ve LDL-K kategorileri için ayarlandıktan sonra, 1.92’lik OR (p
