Studies have assessed the role of frailty in estimating the prognosis of liver cirrhosis patients; however, conflicting findings were found across the reports. The focus of this study was to look into the relationship between frailty and the prognosis of patients with liver cirrhosis. We performed a meta-analysis between August 2020 and January 2021. Data were obtained from articles present in the Web of Science, Embase, and PubMed. The comparison between frailty and the outcomes [ascites, hepatic encephalopathy, mortality, and the model for end-stage liver disease (MELD) score] among liver cirrhosis patients was calculated using a Z test. We included 1,318 liver cirrhosis patients with frailty and 3,579 patients without frailty, retrieved from 9 papers. Frail patients used to have a 1.5-fold and 1.94-fold greater chance of developing ascites [relative risk (RR): 1.65; 95% confidence interval (CI): 1.29, 2.13] and hepatic encephalopathy (RR: 1.94; 95% CI: 1.39, 2.70), respectively, compared with patients without frailty among liver cirrhosis patients. We also revealed that liver cirrhosis patients with frailty had higher odds of mortality than patients without frailty (RR: 2.10; 95% CI: 1.33, 3.34). Furthermore, a higher MELD score was noted in liver cirrhosis patients with frailty than in patients without frailty (mean difference: 2.07; 95% CI: 1.08, 3.07). Frailty is an important predictor of ascites, hepatic encephalopathy, mortality, and a higher MELD score among liver cirrhosis patients.
Keywords: Liver cirrhosis; frailty; clinical outcome; prognosis
Karaciğer sirozu hastalarının prognozunu tahmin etmede kırılganlığın rolü çeşitli çalışmalarda değerlendirilmiştir ancak bulgular arasında çelişkiler söz konusudur. Bu çalışmada, karaciğer sirozu olan hastalarda kırılganlık ile prognoz arasındaki ilişkiyi incelemek amaçlandı. Ağustos 2020-Ocak 2021 arasında bir metaanaliz gerçekleştirildi. Veriler, Web of Science, Embase ve PubMed'de bulunan makalelerden elde edildi. Karaciğer sirozu hastalarında kırılganlık ve sonuçlar [asit, hepatik ensefalopati, mortalite ve son dönem karaciğer hastalığı modeli (model for endstage liver disease 'MELD') skoru] arasındaki karşılaştırma bir Z testi kullanılarak hesaplandı. Dokuz çalışmada yer alan, kırılganlığı olan 1.318 ve kırılganlığı olmayan 3.579 karaciğer sirozu hastası araştırmaya dâhil edildi. Kırılgan hastalarda, kırılgan olmayan hastalara kıyasla asit ve hepatik ensefalopati gelişme olasılığının sırasıyla 1,5 kat [rölatif risk (RR): 1,65; %95 güven aralığı (GA): 1,29, 2,13] ve 1,94 kat (RR: 1,94; %95 GA: 1,39, 2,70) daha fazla olduğu bulundu. Kırılgan karaciğer sirozu hastalarının, kırılgan olmayan hastalara göre daha yüksek mortalite olasılığına sahip olduğu da izlendi (RR: 2,10; %95 GA: 1,33, 3,34). Ayrıca kırılgan karaciğer sirozu hastalarında, kırılgan olmayanlara göre daha yüksek bir MELD skoru kaydedildi (ortalama fark: 2,07; %95 GA: 1,08, 3,07). Kırılganlık, karaciğer sirozu hastalarında asit, hepatik ensefalopati, mortalite ve daha yüksek MELD skoru için önemli bir öngördürücüdür.
