Tüberküloz Tedavisinde Glutamin: Umut Vaat Eden Hepatoprotektif Etki, Ancak Yanıtlanmamış Klinik Sorular

Year 2026, Volume: 7 Issue: 3, 43 - 44, 10.01.2026

Abstract

Bu mektup, Adikwu ve arkadaşlarının Eurasian Journal of Toxicology'de yayınlanan ve glutaminin antitüberküloz ilaçlara (RIPE) bağlı hepatotoksisiteye karşı koruyucu etkilerini gösteren çalışmasını değerlendirmektedir. Çalışmanın glutamin takviyesiyle karaciğer enzimlerinde ve histolojisinde sağladığı iyileşme umut verici olsa da, klinik açıdan üç kritik sınırlılığa dikkat çekilmektedir. Birincisi, glutaminin Mycobacterium tuberculosis bakterisinin nitrojen metabolizmasını destekleyerek bakteriyel büyümeyi artırma riskidir. İkincisi, glutaminin RIPE rejimi ile olası farmakokinetik etkileşimleri ve ilacın etkinliğini azaltma potansiyelidir. Üçüncüsü ise preklinik çalışmada kullanılan yüksek dozların malnütre tüberküloz hastalarına güvenli bir şekilde uyarlanması sorunudur. Sonuç olarak, glutaminin klinik kullanımından önce enfekte modellerde yapılacak ileri çalışmalara ihtiyaç duyulduğu vurgulanmaktadır.

Glutamine in Tuberculosis Treatment: Promising Hepatoprotection but Unanswered Clinical Questions

Year 2026, Volume: 7 Issue: 3, 43 - 44, 10.01.2026

Abstract

This letter discusses the study by Adikwu et al. published in the Eurasian Journal of Toxicology, which demonstrated the hepatoprotective effects of glutamine against antituberculosis drug-induced liver injury (RIPE). While the restoration of liver enzymes and histological improvement with glutamine supplementation is promising, we highlight three critical limitations from a clinical perspective. First is the risk that glutamine might support the growth of Mycobacterium tuberculosis due to the bacterium's nitrogen metabolism. Second is the potential for pharmacokinetic interactions between glutamine and the RIPE regimen that could compromise drug efficacy. Third is the challenge of translating high preclinical doses to often malnourished tuberculosis patients safely. We conclude that further studies using infected models are essential before considering glutamine for clinical application.
