Abstract
Aim: In the postmortem period, endogenous ethanol can be produced from a variety of substrates, including decomposed corpses, a variety of bacteria, yeasts, and molds. Many factors can influence postmortem ethanol synthesis, including the time between death and autopsy, environmental temperature and humidity and microorganisms present in the body at the time of death or in the deceased's environment. It's crucial to determine whether ethyl alcohol, which is found in body fluids like putrefaction fluid, vitreous humor, and blood, was consumed prior to death or formed endogenously after death. Non-oxidative minor metabolites of ethanol, ethyl glucuronide, and ethyl sulfate, are commonly used biomarkers to confirm antemortem alcohol intake.
The aim of this study was to determine postmortem endogenous origin ethyl alcohol levels and to evaluate ethyl alcohol and its metabolites determined as a result of the toxicological examination in body fluids obtained from autopsies of decomposed cases.
Materials And Methods: Autopsy reports on decomposed bodies performed in XXX Branch of Forensic Medicine between 2013 and 2020 were reviewed retrospectively. The presence of ethyl alcohol in putrefaction fluid and vitreous humor, as well as the search status and results for its metabolites, were all recorded.
Results: Between 2013 and 2020, 294 (8.4%) of 3418 autopsies revealed evidence of decomposition. Males made up 83.3 % (n:245) and females made up %16,7’si (n:49) of the cases with signs of putrefaction. Ethyl alcohol was discovered in the putrefaction fluid of 174 (59,2%) patients and the vitreous humor of 15 (5.1%) patients.
In 48 (27,6 percent) of the cases where ethyl alcohol was detected in the putrefaction fluid, metabolites such as ethyl sulfate and ethyl glucuronide were searched, but no metabolites were found in 30 of them. In 17 of the cases where no ethyl alcohol metabolite was detected in the putrefaction fluid, the ethyl alcohol level was below 50 mg/dl, between 51 and 100 mg/dl in 11, and above 100 mg/dl in 2 of them.
In cases with no metabolites, the highest ethanol level was 159 mg/dl in the putrefaction fluid.
Conclusion: It was concluded that in all decomposed cases where ethyl alcohol is detected, it is crucial to look for metabolites.

Abstract
Amaç: Çürümüş cesetlerde, postmortem dönemde birçok bakteri, maya ve küf türü, çeşitli substratlardan endojen etanol üretilebilir. Ölüm ile otopsinin yapıldığı zaman arasındaki süre, çevre ısısı ve nem düzeyi, ölüm anında vücutta bulunan veya ölenin bulunduğu ortamdaki mikroorganizmalar gibi pek çok değişken postmortem etanol sentezini etkileyebilir. Çürümüş olgularda, vücut sıvılarında saptanan etil alkolün ölümden önce mi tüketildiği, yoksa ölümden sonra endojen mi oluştuğunun ayırt edilmesi önemlidir. Etanolün non-oksidatif minor metabolitlerinden etil glukuronid ve etil sülfat, antemortem alkol alımını doğrulamak amacıyla sıklıkla kullanılan biyobelirteçlerdir.
Bu çalışmada otopsi yapılan çürümüş olguların vücut sıvılarında yapılan toksikolojik incelemeler sonucunda saptanan etil alkol ve metabolitlerinin değerlendirilmesi, postmortem endojen kaynaklı etil alkol düzeylerinin belirlenmesi amaçlanmıştır.
Gereç Ve Yöntem: XXX Adli Tıp Şube Müdürlüğünde 2013-2020 yılları arasında çürümüş cesetlere yapılan otopsi raporları retrospektif dosya taraması şeklinde incelenmiştir. Çürüme sıvısı ve göz içi sıvısında etil alkol saptanma durumu, metabolitlerinin aranma durumu ve sonuçları kaydedilmiştir.
Bulgular: 2013-2020 yılları arasında yapılan toplam 3418 otopsinin 294’ünde (%8.4) çürüme bulguları saptanmıştır. Çürüme bulguları saptanan olguların %83.3’ü (n:245) erkektir. Çürümüş olguların 174’ünde (%59,2) çürüme sıvısında, 15’inde (%5,1) göz içi sıvısında etil alkol saptanmıştır.
Çürüme sıvısında etil alkol saptanan olguların 48’inde (%27,6) etil alkol metabolitleri olan etil sülfat ve etil glukuronid aranmış, bunların 30’unda metabolit saptanmamıştır. Çürüme sıvısında etil alkol metaboliti saptanmayan olguların 17’sinde etil alkol düzeyi 50 mg/dl’nin altında, 11'inde 51-100 mg/dl arasında, 2’sinde 100 mg/dl’nin üzerindedir.
Metabolit saptanmayan olgulardaki en yüksek etanol düzeyi, çürüme sıvısında 159 mg/dl’dir.
Sonuç: Etil alkol saptanan tüm çürümüş olgularda mutlaka metabolitlerin de aranmasının önemli olduğu sonucuna varılmıştır.
