Role of granulocyte colony stimulating factor in the treatment of cirrhosis of liver: a systematic review.

OBJECTIVE: We performed a systematic review to analyze the benefits of and risk factors associated with granulocyte colony stimulating factor (GCSF) in patients with liver cirrhosis.

METHODS: PubMed, Scopus, and Embase were searched for randomized controlled trials and case-control studies that compared the use of GCSF with another treatment or control group. The Jadad and Newcastle-Ottawa scales were used to assess the risk of bias in the included studies. The primary outcome studied was mortality; and the secondary outcomes were the disease severity score, liver transplantation criteria, complications, CD34+ cell count, adverse events, and health-related quality of life (HRQOL). PROSPERO registration number CRD42023416014.

RESULTS: The initial search yielded 2,235 studies, of which seven studies of 670 patients with liver cirrhosis were included. Multiple cycles of GCSF significantly improved the survival rate, disease severity score, CD34+ cell count, and HRQOL; and significantly reduced the incidences of liver transplantation, ascites, infection, and hepatic encephalopathy. Fatigue and backache were the most commonly reported adverse events.

CONCLUSION: GCSF significantly improves the survival rate and disease severity scores, and reduces the incidence of complications in patients with liver cirrhosis. The administration of GCSF is likely to be effective in patients awaiting liver transplantation.
