Effect of Granulocyte Colony-stimulating Factor and Erythropoietin on Patients with Acute-on-chronic Liver Failure

Plasma Exchange in Patients of Acute on Chronic Liver Failure: An Observational Study in Bangladesh

Background

Therapeutic plasma exchange (PLEX) removes toxins and different mediators from plasma in patients with acute-on-chronic liver failure (ACLF).

Aim

To observe the safety and outcome of PLEX in ACLF patients in Bangladesh.

Materials and methods

Twenty-eight patients with ACLF attending Bangabandhu Sheikh Mujib Medical University from September 2020 to May 2021 were enrolled in the study. The patients were given different treatment modalities and followed up for 3 months or up to death. The patients were divided into two groups, each containing 14 patients of ACLF. One group of 14 patients received standard medical therapy (SMT) for ACLF and the second group of 14 patients received SMT plus PLEX.

Results

At 90 days, a total of 13 patients (46.43%) survived, of them 8 (57.1%) belonged to PLEX group and 5 (35.7%) were from SMT group. Serum bilirubin and ALT declined significantly after 7 and 30 days but not after 90 days in PLEX group in comparison to SMT group (p <0.05) but other biochemical parameters were not significantly different (p >0.05) between these two groups. Significant (p <0.05) improvement of MELD, MELD-Na, and AARC scores was observed in each group from baseline to subsequent first, second, and third follow-up but no significant (p >0.05) difference was observed in between two groups. Binary logistic regression analysis found that bilirubin, MELD score, MELD-Na score, and AARC score were predictors of mortality.

Conclusion

The study presented here has shown that PLEX is safe in Bangladeshi in ACLF patients, but its efficacy remains to be checked in large-scale randomized trial or in combination therapy with other procedures in ACLF patients.

Therapeutic Effect and Safety of Granulocyte Colony-Stimulating Factor Therapy for Acute-On-Chronic Liver Failure: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Background and Aims: Granulocyte colony-stimulating factor (G-CSF) has been proposed as a therapeutic option for patients with acute-on-chronic liver failure (ACLF). However, its clinical efficacy remains debatable. This study aimed to synthesize available evidence on the efficacy of G-CSF in ALCF.

Methods: The Cochrane Library, CNKI, MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov were searched from inception until September 2021. After qualitative evaluation of the included literature, the included studies were analyzed.

Results: Seven studies were included in this meta-analysis. Overall, G-CSF therapy was not associated with a reduced risk of death (30-day survival, OR = 1.55, 95% CI: 1.00, 2.38, P = 0.05; 60-day survival, OR = 1.50, 95% CI: 0.95, 2.36, P = 0.08; 90-day survival, OR = 1.61, 95% CI: 0.99, 2.62, P = 0.05) or complication including occurrence of infections infection (OR = 0.66, 95% CI: 0.41, 1.05, P = 0.08), bleeding (OR = 1.50, 95% CI: 0.58, 3.89, P = 0.41), and hepatorenal syndrome (OR = 0.56, 95% CI: 0.25, 1.24, P = 0.15). Moreover, it had no obvious beneficial effects on the model of end-stage liver disease score (30-day SMD = −3.31, 95%CI: −7.42, 0.81, P = 0.12; 60-day SMD = −1.23, 95% CI: −5.21, 2.75, P = 0.54; 90-day SMD = −2.29, 95%CI: −4.94, 0.37, P = 0.09). Sensitivity analyses showed that patients in Asia had improved survival (30-day OR = 2.76, 95%CI: 1.43, 5.35, P = 0.003; 60-day OR = 2.83, 95% CI: 1.39, 5.73, P = 0.004; 90-day OR = 2.92, 95% CI: 1.34, 6.36, P = 0.007).

Conclusions: Our findings suggest that, currently, G-CSF cannot be recommended for the treatment of ACLF.

Comparative role of tenofovir versus entecavir for treating patients with hepatitis B virus-related acute on chronic liver failure

INTRODUCTION

The aim of the study was to compare the safety and efficacy of tenofovir versus entecavir for treatment of naive acute on chronic liver failure (ACLF) due to hepatitis B virus (HBV) (ACLF-B).

METHODS

Thirty-two patients aged 14-65 years were enrolled in the study. Diagnosis of ACLF was confirmed by clinical condition, biochemical analysis, and virological data. The causes of both chronic liver damages and acute insult in all patients were HBV. They were expressing HBV DNA in the sera, positive for IgM anti-HBc, had increased levels of serum bilirubin, compromised prothrombin time; and more than 50% patients had encephalopathy. The standard dose of tenofovir and entecavir was given.

RESULTS

The antiviral effects of tenofovir and entecavir were evident as most patients became negative for HBV DNA in the sera after 90 days of therapy. Also, the levels of serum bilirubin, CTP (Child-Turcotte-Pugh) and MELD (model for end-stage liver disease) score exhibited significant improvement due to antiviral therapy. Although the improvement of liver functions, and liver damages were detected in patients receiving both tenofovir and entecavir, the survival of the patients was significantly higher in those receiving tenofovir compared to entecavir-treated patients.

CONCLUSION

This prospective study with limited number patients provides a challenge to assess the real potential of tenofovir over entecavir as therapeutic option for ACLF-B by conducting a multicenter clinical trial enrolling patient of different races and background.
