[Systematic analysis of liver failure accompanied with hemophagocytic syndrome in adults].

Objective: To retrospectively analyze literature reports and summarize the clinical characteristics of liver failure in patients accompanied with adult hemophagocytic syndrome (HPS). Methods: The Wanfang, CNKI, VIP, PubMed, and Ovid databases were searched for relevant literature on liver failure patients accompanied with adult HPS published from January 1980 to May 2022. The final included literature was systematically reviewed after screening. Results: There were a total of 77 liver failure cases accompanied with adult HPS, with an average age of (41.8 ± 12.5) years. The most common clinical manifestations of these cases were persistent high fever, fatigue, gastrointestinal symptoms, and severe jaundice. The imaging changes were not specific, and the most common was hepatosplenomegaly. Laboratory examination showed a significant increase in serum total bilirubin, lactate dehydrogenase, triglycerides, and soluble interleukin-2 receptor levels, as well as serum ferritin, while there was a decrease in prothrombin activity, natural killer cell activity, and hemocytopenia of two or more lineages in peripheral blood. Myelogram examination showed hemophagocytosis. Adult HPS secondary to infection was more likely to be accompanied with liver failure (55.8%), with an overall case fatality rate of 84.4%. Conclusion: Patients with liver failure accompanied with adult HPS have an extremely high mortality rate and a poor prognosis. Early diagnosis and treatment are the keys to improving the prognosis.
