Thrombopoietin-receptor agonists in perioperative treatment of patients with chronic liver disease

Efficacy and Safety of Thrombopoietin Receptor Agonist (TPO-RA) in Patients with Chronic Liver Disease: A Systematic Review and Meta-Analysis

Context: The TPO-receptor agonist (TPO-RA) has been extensively studied for its use in thrombocytopenia. Objectives: We aimed to systematically analyze the efficacy and safety of TPO-RA in chronic liver disease patients. Methods: The study population consisted of adults with chronic liver disease. The intervention was TPO-RA. The primary outcome was the efficacy of TPO-RA (increase in thrombocyte levels and likelihood of avoiding thrombocyte transfusion pre-operatively), while the secondary outcome was the safety of TPO-RA. The demographics of the study and the usage of TPO-RA medications were used to classify the research. Results: This review consisted of 1529 chronic liver disease patients who received TPO-RA and 911 who received a comparator (placebo or thrombocyte transfusion). The TPO-RA significantly increased thrombocyte levels by 34.59 × 109/L (P < 0.00001). The use of TPO-RA pre-procedure reduced the likelihood of pre-operative platelet transfusion and up to seven days following the scheduled procedure by 88% (P < 0.00001). TPO-receptor agonist was not associated with all-cause mortality (P = 0.77) or an increase in thrombosis events, with a pooled OR of 1.36 (P = 0.43). According to a meta-regression analysis, the population may explain the heterogeneity. Subsequent leave-one-out sensitivity analysis of the thrombocyte level change after TPO-RA revealed that no single study was accountable for the heterogeneity of thrombocyte level changes. Conclusions: The use of TPO-RA increases the thrombocyte levels of chronic liver disease patients and reduces the odds of needing thrombocyte transfusion pre-operatively. TPO-receptor agonist is also safe to use, with no increase in mortality risk or thrombosis risk.

Practice Guidelines of the Central European Hepatologic Collaboration (CEHC) on the Use of Thrombopoietin Receptor Agonists in Patients with Chronic Liver Disease Undergoing Invasive Procedures

BACKGROUND

Second-generation thrombopoietin receptor agonists (TPO-RAs) are emerging as the new standard for managing thrombocytopenia (TCP) in patients with chronic liver diseases (CLDs) undergoing scheduled procedures. However, practical guidance for their routine use in CLD patients undergoing specific invasive procedures is lacking.

METHODS

These practice guidelines were developed by the Initiative Group for Central European Hepatologic Collaboration (CEHC), composed of nine hepatologist/gastroenterologist experts from Central Europe. Using an adapted Delphi process, the CEHC group selected ten invasive procedures most relevant to the hepatology/gastroenterology setting in the region. Consensus recommendations for each invasive procedure are reported as a final percentage of expert panel responses.

RESULTS

A consensus was agreed that TPO-RAs should be considered for raising platelet count in CLD patients undergoing scheduled abdominal surgery, high-bleeding risk dentistry, endoscopic polypectomy, endoscopic variceal ligation, liver biopsy, liver surgery, liver transplantation and percutaneous ablation, but it was also agreed that they are less beneficial or not necessary for endoscopy without intervention and paracentesis.

CONCLUSIONS

Using a modified Delphi method, experts reached an agreement for TCP management in CLD patients undergoing ten invasive procedures. These practice guidelines may help with decision making and patient management in areas where clinical evidence is absent or limited.
