Risk of Treatment Failure: Response to Czobor and Volavka

Abstract Background Although achieving histologic remission in ulcerative colitis is established, the incremental benefit of achieving histologic remission in patients with Crohn disease (CD) treated to a target of endoscopic remission is unclear. We evaluated the risk of treatment failure in patients with CD in clinical and endoscopic remission by histologic activity status. Methods In a single-center retrospective cohort study, we identified adults with active CD who achieved clinical and endoscopic remission through treatment optimization. We evaluated the risk of treatment failure (composite of clinical flare requiring treatment modification, hospitalization, and/or surgery) in patients who achieved histologic remission vs persistent histologic activity through Cox proportional hazard analysis. Results Of 470 patients with active CD, 260 (55%) achieved clinical and endoscopic remission with treatment optimization; 215 patients with histology were included (median age, 33 years; 46% males). Overall, 132 patients (61%) achieved histologic remission. No baseline demographic, disease, or treatment factor was associated with achieving histologic remission. Over a 2-year follow-up, patients with CD in clinical and endoscopic remission who achieved histologic remission experienced a 43% lower risk of treatment failure (1-year cumulative risk: 12.9% vs 18.2%; adjusted hazard ratio, 0.57 [95% confidence interval, 0.35-0.94]) as compared with persistent histologic activity. Conclusions Approximately 61% of patients with active CD who achieved clinical and endoscopic remission with treatment optimization simultaneously achieved histologic remission, which was associated with a lower risk of treatment failure. Whether histologic remission should be a treatment target in CD requires evaluation in randomized trials.

Background and purpose: The incidence of first line ART failure is increasing in the South East Asia region. The main referral hospital in Bali has recorded an increased use of second line ART due to the first line ART failure. This study aims to explore risk factors associated to first line ART failure.Methods: A case control study was conducted among people living with HIV and AIDS at Sanglah Hospital Denpasar who started first line ART between 2004 and 2013. Cases were those who diagnosed as having clinical treatment failure and still on treatment in 2015. Controls were those with no treatment failure. Sex and year of ART initiation were matched between case and control. Data were obtained from medical records that include initial regiments, HIV mode of transmission, the WHO HIV clinical stage, CD4 count, opportunistic infections, body mass index, hemoglobin level, and drug substitution at the beginning and during treatment. Risk factors were analysed using logistic regression.Results: Out of 68 HIV/AIDS patients with clinical ART failure, 72.1% were confirmed with immunological and 36.8% were confirmed with virological failure. Median time before treatment failure was 3.5 years. Factors associated to ART failure were HIV clinical stage IV with (AOR=3.43; 95%CI=1.65-7.13) and being widow/widower (AOR=4.85; 95%CI=1.52-15.53). Patients with TB co-infection have a lower risk for treatment failure due to early diagnosis and treatment through TB-HIV program with (AOR=0.32; 95%CI=0.14-0.70).Conclusions: Higher HIV clinical stage at ART initiation increases the risk of treatment failure. HIV-TB co-infection indirectly reduces the risk of treatment failure.

ObjectiveTo assess the impact of adjunctive antibiotic therapy on uncomplicated skin abscesses.DesignSystematic review and network meta-analysis.Data sourcesMedline, Embase, the Cochrane Central Register of Controlled Trials and ClinicalTrials.gov.Study selectionA BMJ Rapid Recommendation panel provided input on design, important outcomes and the interpretation of the results. Eligible randomised controlled trials (RCTs) included a comparison of antibiotics against no antibiotics or a comparison of different antibiotics in patients with uncomplicated skin abscesses, and reported outcomes prespecified by the linked guideline panel.Review methodsReviewers independently screened abstracts and full texts for eligibility, assessed risk of bias and extracted data. We performed random-effects meta-analyses that compared antibiotics with no antibiotics, along with a limited number of prespecified subgroup hypotheses. We also performed network meta-analysis with a Bayesian framework to compare effects of different antibiotics. Quality of evidence was assessed with The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.ResultsFourteen RCTs including 4198 patients proved eligible. Compared with no antibiotics, antibiotics probably lower the risk of treatment failure (OR 0.58, 95% CI 0.37 to 0.90; low quality), recurrence within 1 month (OR 0.48, 95% CI 0.30 to 0.77; moderate quality), hospitalisation (OR 0.55, 95% CI 0.32 to 0.94; moderate quality) and late recurrence (OR 0.64, 95% CI 0.48 to 0.85; moderate quality). However, relative to no use, antibiotics probably increase the risk of gastrointestinal side effects (trimethoprim and sulfamethoxazole (TMP-SMX): OR 1.28, 95% CI 1.04 to 1.58; moderate quality; clindamycin: OR 2.29, 95% CI 1.35 to 3.88; high quality) and diarrhoea (clindamycin: OR 2.71, 95% CI 1.50 to 4.89; high quality). Cephalosporins did not reduce the risk of treatment failure compared with placebo (moderate quality).ConclusionsIn patients with uncomplicated skin abscesses, moderate-to-high quality evidence suggests TMP-SMX or clindamycin confer a modest benefit for several important outcomes, but this is offset by a similar risk of adverse effects. Clindamycin has a substantially higher risk of diarrhoea than TMP-SMX. Cephalosporins are probably not effective.
