RESUMEN
BACKGROUND: Adult-onset Still's disease (AOSD) typically presents with a high spiking fever, polyarthritis, transient maculopapular rash, neutrophilic leukocytosis, and hepatosplenomegaly. It has a wide spectrum of clinical symptoms ranging from mild to severe, with extensive involvement of almost every organ. Although liver involvement in the form of increased hepatic enzymes and bilirubin is common, no AOSD case with liver involvement as the initial manifestation of AOSD has been reported. CASE SUMMARY: A 35-year-old woman presented to the hepatology department with progressively worsening jaundice for one week. Liver chemistry tests revealed a significantly increased liver enzymes and bilirubin level. Given that the clinical examination was unremarkable, liver biopsy was considered because the patient had a history of AOSD 6 years ago. Liver histopathology revealed that most hepatic lobules were still recognizable. Fusional necrosis was observed around most central veins. A few bridging necrotic zones were also found. Infiltration of multiple plasma cells were observed in the necrotic zone, and the reticular scaffold was still expanded. Additionally, no obvious fibrosis was observed in the portal area. Mild mixed inflammatory cell infiltration was noted in the interstitium of the portal area. Further examination was unremarkable except for a remarkably high level of ferritin. Collectively, a presumptive diagnosis of liver injury secondary to AOSD was made. The hepatic involvement responded well to glucocorticoid treatment. CONCLUSION: This case highlights that hepatic involvement as an initial and sole manifestation could be a pattern of relapsed AOSD. The diagnosis of AOSD should be considered in the case of nonresolving liver injury after the exclusion of common etiologies for liver diseases. A liver biopsy can be useful for the differential diagnosis of liver injury associated with AOSD.
RESUMEN
AIM: To evaluate the clinical outcomes of 240-wk treatment with entecavir (0.5 mg) in Chinese nucleoside-naive patients with cirrhosis. METHODS: A total of 204 nucleoside-naive patients with compensated (n = 96) or decompensated (n = 108) hepatitis B virus (HBV)-induced cirrhosis at the Department of Gastroenterology of the China-Japan Union Hospital (Jilin University, Changchun, China) who were treated with entecavir (0.5 mg) for 240 wk were enrolled in this study. Liver biopsy samples obtained from 38 patients prior to treatment (baseline) and at week 240 were evaluated by different independent histopathologists. Efficacy assessments included the proportions of patients who achieved an HBV DNA level < 500 copies/mL, the association of interleukin-28B genetic variation with antivirus therapy, clinical outcomes, and histologic improvement. Changes in liver disease severity were analyzed, and liver histologic evaluation was performed in 38 patients with paired biopsies. Student t tests were used to compare the means of continuous variables between the groups, and the proportions of patients who achieved the endpoints were compared using the χ(2) test. RESULTS: At week 240, 87.5% of the patients with compensated cirrhosis and 92.6% of the patients with decompensated cirrhosis achieved a HBV DNA level < 500 copies/mL. Three patients had genotypic entecavir resistance within the 240-wk period. No significant association was observed between virologic response and interleukin-28 genotype (CT, 88.2% vs CC, 90.6%). The proportion of patients with Child-Pugh class A disease was significantly increased at week 240 (68%) from the baseline (47%; P < 0.01). The proportion of patients with Child-Pugh class B disease was significantly decreased at week 240 (25%) from the baseline (39%; P = 0.02). In the patients with paired liver biopsies, the mean reduction in the Knodell necroinflammatory score from the baseline was 3.58 ± 1.03 points (7.11 ± 1.80 vs 3.53 ± 1.35, P < 0.01). The mean reduction in Ishak fibrosis score from the baseline was 1.26 ± 0.64 points (5.58 ± 0.50 vs 4.32 ± 0.81, P < 0.01). CONCLUSION: Entecavir is an effective treatment option for patients with HBV-related compensated or decompensated cirrhosis that can result in sustained virologic suppression and histologic improvement.
