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

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.

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.

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.

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.
