Clinical characteristics of 96 patients with drug-induced acute liver failure: a comparison between Traditional Chinese and Western Medicine

Abstract Objective To compare the causes, clinical symptoms, laboratory test results, and prognosis in patients with acute liver failure (ALF) induced by traditional Chinese medicines (TCM) and by Western Medicines (WM). Methods The medical histories of patients who were diagnosed with drug-induced ALF (DALF) ( n = 96) after hospitalization in the 302 Military Hospital between January 2010 and December 2015 were retrospectively examined. Results Fifty-eight of the 96 DALF patients (60.4%) had a hepatocellular pattern of DALF, 16 patients (16.7%) had a cholestatic pattern, and 22 patients (22.9%) had a mixed pattern. DALF resolved in 24 patients (25.0%). Twenty-five patients (26.0%) developed chronic liver injury, 43 patients (44.8%) died, and 4 patients (4.2%) underwent liver transplantation. There were 42 ALF patients (43.8%) who received WM, and 32 ALF patients (33.3%) who received TCM. TCM-induced ALF patients had a higher average age [42.4 ± 18.4) vs (33.5 ± 17.9) years, P = 0.04] and higher creatinine and urine nitrogen levels [(155.2 ± 108.8) vs (97.5 ± 130.4) mmol/L, P = 0.047; (9.1 ± 7.7) vs (4.3 ± 5.0) mmol/L, P = 0.002, respectively]. Patients with TCM-induced ALF exhibited an increased risk of renal injury [odds ratio ( OR ), 3.75; 95% confidence interval ( CI ), 1.330-10.577]. The 14 patients with TCM-induced ALF who died exhibited higher creatinine levels than the 18 patients with TCM-induced ALF patients who survived [(218.7 ± 111.6) vs (105.8 ± 78.4) mmol/L, P = 0.002]. They were also more likely to exhibit ascites (85.7% vs 44.4%, P = 0.017) and hepatorenal syndrome (78.6% vs 22.2%, P = 0.002). Conclusion TCM-induced ALF was more likely to be accompanied by renal injury than was WM-induced ALF, especially in TCM-induced ALF patients who died.
