🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the last 12 months.

1. Efficacy and safety of 24 antibiotics for group A streptococcal pharyngitis: a network meta-analysis of 64 randomized controlled trials.

Frontiers in public health (2026) - Network Meta-Analysis

Key Findings

  • Across 64 RCTs with 23,287 participants, cefdinir improved early bacterial eradication versus penicillin V (OR 3.09; 95% CI 1.60-6.01).
  • Azithromycin had inferior early eradication versus penicillin V (OR 0.53; 95% CI 0.32-0.90), poorer late eradication (OR 0.38; 95% CI 0.25-0.62), and increased adverse-event concerns.

📋 Practice Implication: Keep penicillin as first-line therapy for confirmed GAS pharyngitis, and reserve cephalosporin alternatives such as cefdinir for selected failures or intolerance rather than routine broad-spectrum use.

2. Long-term effects of a multifaceted antimicrobial stewardship program, with audit and feedback, on acute sore throat in primary care - A randomized controlled trial.

International journal of infectious diseases (2026) - Randomized Controlled Trial

Key Findings

  • At baseline, approximately two-thirds of pharyngotonsillitis cases were guideline-concordant, and the intervention did not improve guideline adherence at 6, 12, or 18 months.
  • The 6-month audit-feedback antimicrobial stewardship program did not improve the proportion of antibiotic-treated cases with a positive streptococcal test.

📋 Practice Implication: Do not assume education plus audit-feedback is enough to change sore-throat prescribing; clinics may need workflow, decision-support, or accountability changes tied directly to testing and prescribing behavior.

3. Multi-center investigation on the influence of clinical characteristics and molecular group A streptococci diagnostics on the management of tonsillopharyngitis in pediatric practices in Berlin-BASE study.

European journal of pediatrics (2026) - Randomized Controlled Trial

Key Findings

  • In 1,111 pediatric patients, overall antibiotic use remained high at 67.2%, with no significant reduction from rapid molecular point-of-care testing versus standard care.
  • Antibiotic prescribing increased strongly with McIsaac score of at least 3 (OR 4.67; 95% CI 3.22-6.79), and 95.5% of test-positive children received antibiotics versus 10.8% of test-negative children.

📋 Practice Implication: Molecular GAS testing should be paired with explicit pediatric stewardship rules, because test availability alone may not lower prescribing when clinical scores and positive results strongly drive treatment.

4. Surgical Treatments for Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Adenitis Syndrome: Systematic Review and Network Meta-analysis.

Otolaryngology--head and neck surgery (2025) - Network Meta-Analysis

Key Findings

  • Across nine studies totaling 691 patients, surgery increased the likelihood of PFAPA symptom resolution versus medical treatment (OR 11.7; 95% CI 2.14-63.94).
  • RCT-only sensitivity analysis also favored tonsillectomy (OR 34.15; 95% CI 3.77-308.95), while pooled symptom recurrence was 13.6% after tonsillectomy versus 37.5% after intracapsular tonsillectomy.

📋 Practice Implication: For children with well-characterized PFAPA and recurrent pharyngitis episodes, tonsillectomy can be discussed as a disease-modifying option while acknowledging heterogeneity and operative risk.

5. A probiotic containing L. plantarum and P. acidilactici strains for treating upper respiratory infection in children aged 6 months to 5 years: a randomized, double-blind trial.

European journal of pediatrics (2025) - Randomized Controlled Trial

Key Findings

  • In 75 children with URI and pharyngitis, the probiotic reduced fever duration by 1.1 days versus placebo (95% CI 0.5-1.7; p = 0.001).
  • Pain or discomfort duration improved by 0.7 days versus placebo (95% CI 0.2-1.2; p = 0.006), with no significant increase in adverse events.

📋 Practice Implication: A strain-specific probiotic may be a reasonable adjunct for viral-appearing pediatric URI with pharyngitis, but it should not substitute for GAS testing or indicated antibiotic therapy.

💡 Summary

Recent pharyngitis evidence reinforces stewardship: penicillin remains preferred for group A streptococcal disease, azithromycin performed poorly, and two pragmatic trials found diagnostics or audit-feedback alone did not reduce antibiotic use. Pediatric and recurrent-throat-syndrome data suggest selective roles for surgery and non-antibiotic adjuncts, but decisions should remain diagnosis-specific and balanced against morbidity.
