Impact of artificial liver plasma perfusion combined with plasma exchange therapy on clinical efficacy and short-term prognosis of hepatitis B virus-related acute-on-chronic liver failure with or without HIV infection.
Article in BMC infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo compare the effectiveness of plasma perfusion combined with plasma exchange (PP + PE) artificial liver support system in patients with hepatitis B virus-associated acute-on-chronic liver failure with and without HIV infection (HBV-ACLF/HIV(+) and HBV-ACLF/HIV(-), respectively) and to assess the clinical value and safety of the artificial liver support system.
methodsThis study involved 162 patients diagnosed with HBV-ACLF and hospitalized at Chengdu Public Health Clinical Medical Center from January 2020 to January 2025, in accordance with the diagnostic criteria of the Chinese Guidelines for the Diagnosis and Treatment of Acute-on-Chronic Liver Failure (2025 edition). Seventeen patients with tumors, severe underlying diseases, or other hepatitis virus infections were excluded. Patients were divided into the HBV-ACLF/HIV(+) and HBV-ACLF/HIV(-) groups. Propensity score matching (PSM) was used to correct baseline bias. Laboratory indices, Model for End-stage Liver Disease score (MELDs), and 28- and 90-day cumulative survival or mortality rates before and after artificial liver therapy were used as effectiveness indicators. Kaplan-Meier analysis was used to plot survival curves, and the log rank test was used to assess survival differences. Cox proportional hazards regression modeling was used for multifactorial analysis to further evaluate the effectiveness of PP + PE therapy and prognostic factors.
resultsIn total, 145 patients with HBV-ACLF were included, with 64 in the HBV-ACLF/HIV(+) group and 81 in the HBV-ACLF/HIV(-) group. After 1:1 PSM, 29 patients remained in each group. Alanine aminotransferase, glutamate transferase, total bilirubin, indirect bilirubin, international normalized ratio, prothrombin time activity, and MELDs significantly improved in both groups after PP + PE treatment (P < 0.05). Before and after PSM, there was no statistically significant difference in 28- or 90-day cumulative survival between the HBV-ACLF/HIV(+) and HBV-ACLF/HIV(-) groups (after PSM: log rank, P = 0.572). Multifactorial Cox regression analysis showed that improvements in total bilirubin, creatinine, leukocytes, blood ammonia, MELDs, international normalized ratio, and prothrombin time activity were associated with better short-term prognosis in patients with HBV-ACLF/HIV(+) (P < 0.005).
conclusionThe PP + PE artificial liver treatment model effectively promotes liver function recovery and improves clinical status in HBV-ACLF patients, including those with HIV co-infection. This provides a valuable basis for clinical management of co-infected cases. Multicenter prospective studies are needed to confirm its long-term efficacy.
