RESUMO
BACKGROUND AND AIM: Gynura segetum (Tusanqi or Jusanqi) is widely used in China as a herbal remedy, however, it has often been associated with hepatic sinusoidal obstruction syndrome (HSOS). Its extent in inducing hepatotoxicity is not sufficiently understood. Hence, we aimed to identify the characteristic features of Gynura segetum associated HSOS. METHODS: A total of 64 patients diagnosed with HSOS induced by gynura segetum were enrolled from eight Chinese tertiary care hospitals between 2008 and 2018. General information regarding diagnosis, disease history, suspected drug use, symptoms and signs, biochemical index, imaging data, liver histology, treatment methods, severity and prognosis were collected and analyzed. RESULTS: The mean age of the enrolled patients were 58.07±11.44 years. Male patients accounted for 64.1% of HSOS patients. The median latency period was 75 days. The number of patients with a definite diagnosis from the eight hospitals was 5 (7.81%), with a misdiagnosis rate of 92.18%. Hepatomegaly, splenomegaly, ascites and lower limbs edema were present in 89.1%, 76.6%, 81.3% and 43.8% of the patients, respectively. The imaging characteristic changes were liver parenchyma echo thickening, uneven density, and hepatic vein stenosis and occlusion. Liver biopsies had characteristic pathological changes. Except for ALT and D-Dimer, liver function and coagulation index at admission and before discharge were not significantly different (p>0.05). The 6-month mortality rate was 77.55%, with upper-gastrointestinal bleeding being the leading cause of death (42.11%). The second leading cause of death was a secondary infection (36.84%), while the third was hepatorenal syndrome (21.05%). CONCLUSION: Gynura segetum related HSOS often presents as progressive hepatic congestion, portal hypertension and liver failure, and has a high mortality and misdiagnosis rate.

Drug-induced liver injury (DILI) is an important liver disease in China, owing to the country's huge population and the availability of a multitude of drugs. Consequently, DILI is becoming an increasingly serious health problem. However, there is not enough relevant epidemiological data, and the clinical features of these patients are not clear. We conducted this study to report the causes and clinical features of DILI in hospitalized patients, and identify the mortality and predictive factors. We retrospectively collected and analyzed the data of all hospitalized patients whose discharge diagnosis was DILI at the Second Xiangya Hospital between January 2011 and December 2014. The data analyses were performed using SAS version 9.2. Among the 469 patients who were diagnosed with DILI at discharge, 361 met the criteria for DILI on re-evaluation. The crude annual incidence rate of DILI was 92.95 cases per 100,000 patients. Chinese herbal medicine was identified as the primary cause of DILI in 36.01 % of the patients. The overall mortality was 8.59 %. Alcohol consumption, use of antituberculosis drugs, serum total bilirubin, direct bilirubin, total protein, albumin, thrombinogen time, international normalized ratio, and the model for end-stage liver disease (MELD) score were significantly correlated with DILI-associated mortality. Among them, the MELD score and albumin were found to be independent predictors of outcome in patients with DILI. Chinese herbal medicine was the primary cause of DILI in the identified patients. The MELD score and albumin were independent predictors of outcome in patients with DILI.
