Abstract

Objective: Alcohol is the most commonly abused substance in the general population. The misuse of alcohol is common and frequently an occult problem. Epidemiological studies suggest that alcohol intake is associated with the risk of coronary arter disease. The challenge for the clinician is to detect alcohol misuse at an early stage. Five active isoenzymes of Lactate dehyrogenase (LDH) can be found in human tissues, and especially LDH5 isoenzyme is high in the liver tissue. Therefore, in this study, we investigated the effect of alcohol consumption on the activities of total LDH and its isoenzymes. Methods: The study group consisted of 64 alcohol drinkers men, and the control group consisted of 48 healthy men. Venous blood samples were obtained from a cubital vein 8-12 hours after alcohol consumption or the dinner for study group or control group. Serum activities of GGT and total LDH were measured by commercial kit procedure, and LDH isoenzymes were determined by Helena electrophoresis. Results: LDH5 and GGT activities of the alcohol group were statistically higher than the control group (p<0.01), and LDH1 and LDH2 activities were lower than the control (p<0.01 and p<0.02, respectively). There is no statistically significant difference between alcohol group and control group in view of LDH3, LDH4 and total LDH activities. Conclusions: Alcohol group had higher LDH5 and GGT activities than control group. Therefore, the assay of LDH5 and/or GGT activities can be taken as early markers for alcohol abuse.

Özet

Amaç: Alkol toplumda en yaygın suistimal edilen madde olup bu yanlış kullanım genel ve gizli bir problemdir. Epidemiyolojik çalışmalar alkol kullanımı ile koroner arter hastalığının ilişkili olduğunu belirtmektedir. Klinisyen hekimlerin isteği erken dönemde yanlış alkol kullanımının saptanmasıdır. İnsan dokularında LDH enziminin beş izoenzimi vardır ve bunlardan özellikle LDH5 izoenzimi karaciğer dokusunda yüksek miktarlardadır. Bu nedenlerle biz bu çalışmamızda alkol kullanımının total LDH ve LDH5 izoenzimlerine olası etkilerini araştırdık. Yöntem: Çalışma gruplarımız alkol kullanan 64 erkek ve alkol kullanmayan 48 erkek kişiden oluşmaktadır. Venöz kan örnekleri çalışma grubunda alkol alımından 8-12 saat sonra ve kontrol grubunda akşam yemeğinden 8-12 saat sonra alındı. GGT ve total LDH aktiviteleri ticari kit yöntemlerine göre, ve LDH5, LDH2, LDH3, LDH4 ve LDH5 izoenzimleri Helena elektroforeziyle saptandı. Bulgular: LDH5 ve GGT aktiviteleri alkol grubunda kontrol grubuna kıyasla istatistiksel olarak daha yüksek (p<0.01) iken LD1 (p<0.01) ve LDH2 (p<0.02) aktiviteleri alkol grubunda istatistiksel olarak daha düşüktür (p<0.01). Total LDH, LDH3 ve LDH4 aktiviteleri gruplar arasında fark göstermemiştir. Sonuç: Alkol grubumuzun LDH5 ve GGT enzim aktiviteleri alkol grubunda belirgin olarak yüksektir ve bu nedenle LDH5 ve/veya GGT enzim aktivitelerinin ölçümü; alkol suistimalinin erken belirteçleri olabilir.
