Insights
Antibiotics do not prevent preterm birth (PTB). A review of clinical trials found mixed results, and routine antibiotic prophylaxis is not recommended for preventing PTB.
Area of Science:
- Obstetrics and Gynecology
- Neonatal Medicine
- Infectious Diseases
Background:
- Preterm birth (PTB) is a leading cause of infant mortality and illness.
- Infection is a known risk factor for PTB.
Purpose of the Study:
- To review scientific literature on antibiotic use for PTB prevention.
- To evaluate the efficacy of antibiotics in preventing PTB.
Main Methods:
- PubMed database search for clinical trials and meta-analyses (1990-2011).
- Keywords: "antibiotics or antimicrobials" and "preterm."
- Full-text review of 31 selected studies.
Main Results:
- Sixty-seven abstracts were initially identified.
- Thirty-one studies (26 trials, 5 meta-analyses) were reviewed.
- Antibiotic use for PTB prevention yielded mixed results, with no clear overall benefit.
Conclusions:
- Routine antibiotic prophylaxis is not advised for PTB prevention.
- Further research may be needed to clarify specific scenarios, if any, where antibiotics could be beneficial.
Objective:
Preterm birth (PTB) remains a major cause of neonatal morbidity and mortality. The association between PTB and infection is clear. The purpose of this report is to present a focused review of information on the use of antibiotics to prevent PTB.
Methods:
We performed a search of the PubMed database restricted to clinical trials or meta-analyses published in English from 1990 through May 2011 using keywords "antibiotics or antimicrobials" and "preterm."
Results:
The search yielded 67 abstracts for review. We selected 31 clinical trials (n = 26) or meta-analysis (n = 5) for further full-text review. Discussion of each eligible clinical trial, its specific inclusion criteria, antibiotic regimen used, and study results are presented. Overall, trials evaluating antibiotic treatment to prevent preterm birth have yielded mixed results regarding any benefit.
Conclusion:
Routine antibiotic prophylaxis is not recommended for prevention of preterm birth.
