Methods We retrospectively reviewed the medical records of 58 patients with UC who had 73 pregnancies and 3 patients with newly developed UC during pregnancy. We recorded the rate of relapse of UC; the relationship between medication use and UC relapse during pregnancy; treatment for relapse; and the incidence of pregnancy, childbirth, and newborn abnormalities. Results UC was in remission at conception in 78% of the patients. The relapse rate during pregnancy was 27.3%, with most relapses occurring during the second and third trimesters. The relapse rate in patients in whom any UC drug had been discontinued was 50%, a rate significantly higher than the 20.5% of patients for whom all medications were continued (p = 0.016). Thiopurine was discontinued in 60% (6/10) of patients at conception, and the disease relapsed in 50% (3/6) of the patients. Most relapses were successfully treated with 5-aminosalicylic acid or corticosteroids. UC relapse occurred in 26.1% (18/70) of the patients after delivery, mostly within 2 months. Pregnancy, delivery, or neonatal abnormalities occurred in 23.3% (17/73) of patients. In two of the three patients with new-onset UC, UC was severe and required intensive care; however, the pregnancies continued uneventfully. Conclusion Although the progress of pregnancies complicated by UC was mostly uneventful, discontinuing medication carries the risk of UC relapse. Thus, appropriate management of medical treatments for UC during pregnancy is important.</p>","PeriodicalId":13719,"journal":{"name":"Internal Medicine","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142619779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the efficacy of anti-influenza drugs, particularly among young patients at a low risk of complications, has rarely been evaluated. Therefore, we evaluated the efficacy of anti-influenza drugs against seasonal influenza in healthy young and middle-aged adults. Methods A systematic review and network meta-analysis were conducted. The Cochrane Central Register of Controlled Trials and Medical Literature Analysis and Retrieval System Online were searched for original articles reporting double-blind, randomized controlled trials published up to the end of July 2023. Clinical trials that tested the efficacy of anti-influenza drugs in young and middle-aged patients with seasonal influenza were also included. The primary outcome was time to fever alleviation. The efficacy and adverse effects of these treatments were estimated using a Bayesian hierarchical random-effects model and a Markov chain Monte Carlo simulation. Results In total, 24 articles with 34 treatments and 8,949 individuals were included. Oseltamivir (300 mg/day for 5 days) showed the largest reduction in time to fever alleviation by -19.1 [95% confidence interval (CI): -29.4, -10.7] h compared with a placebo. Baloxavir marboxil (40 mg/day) reduced the time to symptom alleviation by -28.2 (95% CI: -42.7, -13.7) h, and peramivir (300 mg/day) administered by intravenous infusion for 1 day reduced the time to resumption of usual activities by -43.5 (95% CI: -72.8, -14.2) h.
