Short- vs. Long-Course Antibiotic Treatment for Acute Streptococcal Pharyngitis: Systematic Review and Meta-Analysis of Randomized Controlled Trials.

ABSTRACT: BACKGROUND:To evaluate the effectiveness of short courses of antibiotic therapy for patients with acute streptococcal pharyngitis. METHODS:Randomized controlled trials comparing short-course antibiotic therapy (?5 days) with long-course antibiotic therapy (?7 days) for patients with streptococcal pharyngitis were included. Two primary outcomes: early clinical cure and early bacterial eradication. RESULTS:Fifty randomized clinical trials were included. Overall, short-course antibiotic treatment was as effective as long-course antibiotic treatment for early clinical cure (odds ratio (OR) 0.85; 95% confidence interval (CI) 0.79 to 1.15). Subgroup analysis showed that short-course penicillin was less effective for early clinical cure (OR 0.43; 95% CI, 0.23 to 0.82) and bacteriological eradication (OR 0.34; 95% CI, 0.19 to 0.61) in comparison to long-course penicillin. Short-course macrolides were equally effective, compared to long-course penicillin. Finally, short-course cephalosporin was more effective for early clinical cure (OR 1.48; 95% CI, 1.11 to 1.96) and early microbiological cure (OR 1.60; 95% CI, 1.13 to 2.27) in comparison to long-course penicillin. In total, 1211 (17.7%) participants assigned to short-course antibiotic therapy, and 893 (12.3%) cases assigned to long-course, developed adverse events (OR 1.35; 95% CI, 1.08 to 1.68). CONCLUSIONS:Macrolides and cephalosporins belong to the list of "Highest Priority Critically Important Antimicrobials"; hence, long-course penicillin V should remain as the first line antibiotic for the management of patients with streptococcal pharyngitis as far as the benefits of using these two types of antibiotics do not outweigh the harms of their unnecessary use.

Project description:BackgroundFor ventilator-associated pneumonia (VAP), the safety of short-course versus long-course antibiotic therapy is still debated, especially regarding documented VAP due to non-fermenting Gram-negative bacilli (NF-GNB). The aim of this meta-analysis was to assess the rates of recurrence and relapse of VAP in patients receiving short-course (≤8 days) and long-course (≥10-15 days) of antibiotic therapy.MethodsThe protocol for this study was registered in the PROSPERO database (ID: CRD42022365138). We performed an electronic search of the relevant literature and limited our search to data published from 2000 until September 1, 2022. We searched for randomized controlled trials (RCTs) in the United States National Library of Medicine, Cochrane Database of Systematic Reviews (CDSR) and the Cochrane Central Register of Controlled Trials (CENTRAL), Embase, National Institutes of Health PubMed/MEDLINE, web of science and Google Scholar databases. The primary endpoint was the recurrence and relapses of VAP, secondary endpoints were 28-day mortality, mechanical ventilation duration, number of extra-pulmonary infections and length of ICU stay.FindingsWe identified five relevant studies involving 1069 patients (530 patients in the short-course group and 539 patients in the long-course group). The meta-analysis did not reveal any significant difference between short and long-course antibiotic therapy for recurrence and relapses of VAP (odd ratio "OR" = 1.48, 95% confidence intervals (CI) [0.96, 2.28], p = 0.08 and OR = 1.45, 95% CI [0.94, 2.22], p = 0.09, respectively), including those due to NF-GNB (OR = 1.90, 95% CI [0.93, 3.33], p = 0.05 and OR = 1.76, 95% CI [0.93, 3.33], p = 0.08, respectively). No difference was found for 28 days-mortality (OR = 1.24, 95% CI [0.92, 1.67], p = 0.16), mechanical ventilation duration, number of extra-pulmonary infections and length of ICU stay. However, short-course therapy significantly increased the number of antibiotic-free days.InterpretationOur meta-analysis showed that short-course antibiotic therapy did not result in increased number of recurence and relapses of VAP, suggesting that short-course should be preferred to reduce the exposure to antibiotics.FundingNone.

Project description:What is known and objectiveGram-negative bacteremia remains a major health problem around the world. The optimal duration of antibiotic treatment has been poorly defined, and there are significant differences of opinion between clinicians. We conducted this systematic review and meta-analysis to compare the clinical outcomes of short-course and long-course treatments in patients with uncomplicated gram-negative bacteremia.MethodsWe searched public databases (PubMed, EMBASE and Cochrane Library) to identify eligible studies. The primary outcomes were all-cause mortality and the incidence of recurrent bacteremia through day 30. We used the Cochrane risk of bias assessment tool to evaluate the risk of bias for randomized controlled trials (RCTs) and the Newcastle-Ottawa Scale for non-RCTs.Results and discussionSix studies involving 2689 patients were included in the systematic review and meta-analysis. No significant difference was found between short-course and long-course antibiotic treatments in 30-day mortality (risk ratio [RR] 0.85; 95% confidence interval [CI] 0.65-1.13; P = .26), 30-day recurrent bacteremia (RR 1.07; 95% CI 0.68-1.67; P = .78), 90-day mortality (RR 0.84; 95% CI 0.57-1.24; P = .38), 90-day recurrent bacteremia (RR 0.98; 95% CI 0.50-1.89; P = .94), adverse events (RR 1.14; 95% CI 0.89-1.45; P = .30), Clostridium difficile infection (RR 0.86; 95% CI 0.40-1.86; P = .71) or resistance development (RR 1.19; 95% CI 0.66-2.14; P = .57).What is new and conclusionShort-course was non-inferior to long-course antibiotic treatments for patients with uncomplicated gram-negative bacteremia. Considering the drug-related side effects and cost-effectiveness, a shorter duration of antibiotic treatment may be preferable for this particular population. However, additional high-quality RCTs are needed to further assess whether a shorter course of antibiotic treatment is of greater benefit for patients with uncomplicated gram-negative bacteremia.

Project description:ImportanceAlthough both short-course radiotherapy and long-course chemoradiotherapy have been practiced in parallel for more than 15 years, no cost-effectiveness analysis comparing these 2 approaches in patients with locally advanced rectal cancer has been published.ObjectiveTo analyze the cost-effectiveness of short-course radiotherapy vs long-course chemoradiotherapy for the treatment of patients with locally advanced rectal cancer.Design, setting, and participantsThis economic evaluation used a cost-effectiveness model simulating 10-year outcomes for 1 million hypothetical patients aged 65 years with locally advanced rectal cancer treated with either short-course radiotherapy or long-course chemoradiotherapy, followed by surgery and chemotherapy. Utilities and probabilities from the literature and costs from the Healthcare Bluebook and Medicare fee schedules were used to determine incremental cost-effectiveness ratios. It was assumed that long-course chemoradiotherapy would result in higher rates of low anterior resection (LAR). To model preference-sensitive care, a 2-way sensitivity analysis was conducted in which the utilities of the no-evidence-of-disease (NED) states with LAR and abdominoperineal resection (APR) were simultaneously varied. The analysis was repeated for patients with distal rectal tumors. Analysis was conducted from January to October 2018.ExposuresShort-course radiotherapy and long-course chemoradiotherapy.Main outcomes and measuresIncremental cost-effectiveness ratios.ResultsShort-course radiotherapy was the cost-effective strategy compared with long-course chemoradiotherapy (incremental cost-effectiveness ratio, $133 495 per quality-adjusted life-year). Two-way sensitivity analysis revealed that the cost-effective approach for a given patient depended on the utilities for the NED-LAR and NED-APR states. Assuming that a greater proportion of patients with locally advanced distal tumors undergoing long-course chemoradiotherapy (39%) would proceed to LAR compared with those treated with short-course radiotherapy (19%), long-course chemoradiotherapy was the cost-effective approach (incremental cost-effectiveness ratio, $61 123 per quality-adjusted life-year).Conclusions and relevanceShort-course radiotherapy was the cost-effective strategy compared with long-course chemoradiotherapy for patients with locally advanced rectal cancer. The cost-effectiveness of short-course radiotherapy vs long-course chemoradiotherapy was sensitive to the utilities of the NED-LAR and NED-APR health states, highlighting the importance of care that is sensitive to patient preference. Long-course chemoradiotherapy was the cost-effective approach for patients with distal tumors.
