Resumo
Between 50% and 86% of patients with autoimmune hepatitis (AIH) relapse after immunosuppression withdrawal; long-term immunosuppression is associated with increased risk of neoplasias and infections. Chloroquine diphosphate (CQ) is an immunomodulatory drug that reduces the risk of flares in rheumatologic diseases. Our aims were to investigate the efficacy and safety of CQ for maintenance of biochemical remission of AIH in a double-blind randomized trial and to define a subgroup that obtained a greater benefit from its use. A total of 61 patients with AIH in histologic remission (90.1% AIH type 1 [AIH-1]) were randomized to receive CQ 250 mg/day or placebo for 36 months. Of the 61 patients, 31 received CQ and 30 placebo. At baseline, clinical, laboratory, histologic findings, and human leukocyte antigen (HLA) profile were similar between the two groups. Relapse-free survival was significantly higher in the CQ group compared to the placebo group (59.3% and 19.9%, respectively P = 0.039). For those patients completing 3-year treatment, relapse rates were 41.6% and 0% after CQ and placebo withdrawal, respectively. Factors associated with a higher risk of relapse in multiple Cox regression were placebo use (hazard ratio, 2.4; 95% confidence interval [CI], 1.055.5; P = 0.039) and anti-soluble liver antigen/liver-pancreas (anti-SLA/LP) seropositivity (hazard ratio, 5.4; 95% CI, 1.91-15.3; P = 0.002). Although it was not possible to define a subgroup that obtained a greater benefit from CQ according to anti-SLA/LP reactivity or HLA profile, 100% of patients who were anti-SLA/LP-positive (+) relapsed with placebo compared to 50% with CQ (P = 0.055). In the CQgroup, 54.8% had side effects and 19.3% interrupted the drug regimen. Conclusion: CQ safely reduced the risk of relapse of AIH, but it was not possible to define a subgroup that obtained a greater benefit with CQ use, probably because of sample size.
