Safety and Effectiveness of Sulfasalazine in the Treatment of Liver Fibrosis/Cirrhosis.

Обзор

This is a controlled, observational clinical study initiated by investigators to investigate the efficacy and safety of sulfasalazine in the treatment of cirrhosis in patients with cirrhosis. Four cohorts were planned: primary biliary cirrhosis, hepatitis B and C cirrhosis, and alcoholic cirrhosis. The four groups were divided into experimental group and control group, and the experimental group: each group of patients was orally treated sulfasalazine for 12 months, taken three times a day, each time taking 0.5g. The control group did not take sulfasalazine. After 12 months, Observe changes in patients' biochemical and imaging indicators, liver stiffness values, fecal microbiota, and metabolites before and after the use of sulfasalazine.

Подробное описание

This study is a controlled and observational clinical study initiated by the investigators to study the efficacy and safety of sulfasalazine in the treatment of cirrhosis in patients with cirrhosis, and to observe changes in patients' biochemical and imaging indicators, liver stiffness values, fecal microbiota, and metabolites before and after the use of sulfasalazine.

Four cohorts were planned to be included in this study:

Cohort A: Differences in cirrhosis changes with the addition of sulfasalazine to UDCA in PBC patients with an inadequate response to UDCA and treatment-naïve PBC patients.

Cohort B: Differences in changes in cirrhosis in patients with viral hepatitis B cirrhosis compared with the addition of sulfasalazine to antiviral (if possible, the same antiviral) therapy.

Cohort C: Differences in changes in cirrhosis in patients with viral hepatitis C cirrhosis compared with the addition of sulfasalazine to antiviral (if possible, the same antiviral) therapy.

Cohort D: Differences in differences in changes in cirrhosis compared with sulfasalazine in patients with alcoholic hepatitis cirrhosis.

Treatment options:

1. Patients with PBC who did not respond adequately to UDCA: 30 patients with poor response to treated PBC continued to take UDCA, 30 patients with poor response to treated PBC received UDCA+SASP (0.5 g orally three times daily), and 30 patients with poor response received SASP (0.5 g orally three times daily) for 12 months and were followed up for 12 months.

Treatment-naïve PBC patients: 30 treatment-naïve PBC patients took UDCA, and 30 treatment-naïve PBC patients took UDCA+SASP (0.5 g orally three times a day) for 12 months and followed up for 12 months. 2. Treatment group of hepatitis B (hepatitis C) viral liver cirrhosis: 60 patients with hepatitis B (hepatitis C) viral cirrhosis were collected (using the same dose of antiviral drugs), 30 patients with hepatitis B (hepatitis C) viral cirrhosis took antiviral drugs, and 30 patients with hepatitis B (hepatitis C) virus cirrhosis were treated with sulfasalazine (0.5g three times a day) on the basis of taking antiviral drugs, and follow-up observation was observed for 12 months. 3. Treatment group of alcoholic hepatitis cirrhosis: 60 patients with alcoholic cirrhosis were collected, 30 patients with alcoholic cirrhosis did not take antifibrotic drugs, 30 cases of alcoholic cirrhosis took sulfasalazine (0.5g three times a day), and follow-up observation was observed for 12 months.
