CONTEXT: The increasing prevalence of childhood asthma has been associated with low microbial exposure as described by the hygiene hypothesis. OBJECTIVE: We sought to evaluate the evidence of association between antibiotic exposure during pregnancy or in the first year of life and risk of childhood asthma. METHODS: PubMed was systematically searched for studies published between 1950 and July 1, 2010. Those that assessed associations between antibiotic exposure during pregnancy or in the first…

The relationship of prenatal antibiotic exposure and infant antibiotic administration with childhood allergies: a systematic review
TLDR
Although most studies showed significant findings between early antibiotic exposure and asthma, the actual effects are still unclear as intrapartum antibiotic administration, familial factors and confounding by maternal and child infections were often not addressed.
Prenatal antibiotic exposure and childhood asthma: a population-based study
TLDR
Prenatal antibiotic exposure was associated with a dose-dependent increase in asthma risk, but similar associations were observed for maternal antibiotic use before and after pregnancy, suggesting the association is either not directly causal, or not specific to pregnancy.
Antibiotic exposure during pregnancy and childhood asthma: a national birth cohort study investigating timing of exposure and mode of delivery
TLDR
Antibiotic exposure in mid-to-late pregnancy is associated with higher odds of childhood asthma in vaginally born children, but not those born by caesarean section, and mode of delivery may modify the association.

First-Year Antibiotics Exposure in Relation to Childhood Asthma, Allergies, and Airway Illnesses
TLDR
It is indicated that first-year antibiotics exposure could be a strong risk factor for childhood pneumonia, asthma, allergies, and their related symptoms.

Antibiotics in fetal and early life and subsequent childhood asthma: nationwide population based study with sibling analysis
TLDR
Previous positive associations between exposure to antibiotics in fetal and early life and subsequent childhood asthma could have been caused by confounding by shared familial factors, in addition to confounding by respiratory infections.

TLDR
A large, multicentre cohort study that evaluated the association between postnatal antibiotic exposure and CD autoimmunity in human leukocyte antigen (HLA)-positive subjects found no association.

Increased risk of childhood asthma from antibiotic use in early life.
TLDR
Antibiotic use in early life was associated with the development of childhood asthma, a risk that may be reduced by avoiding the use of BS cephalosporins.
Antibiotic Use in Children Is Associated With Increased Risk of Asthma
TLDR
Evidence is provided that the use of antibiotics in the first year of life is associated with a small risk of developing asthma, and this risk increases with the number of courses of antibiotics prescribed.
Does antibiotic exposure during infancy lead to development of asthma?: a systematic review and metaanalysis.
TLDR
Exposure to at least one course of antibiotics in the first year of life appears to be a risk factor for the development of childhood asthma.
Early life exposures and risk of atopy among Danish children.
TLDR
Wheezy bronchitis before the age of 2 years seems to be independent of familial predisposition to atopic disease and significantly increases the likelihood for development of atopy in genetically susceptible individuals.
Early childhood infectious diseases and the development of asthma up to school age: a birth cohort study
TLDR
Repeated viral infections other than lower respiratory tract infections early in life may reduce the risk of developing asthma up to school age.
Determinants of the incidence of childhood asthma: a two-stage case-control study.
TLDR
This study allowed the authors to identify the most influential determinants of childhood asthma among 47 predictors assessed for the prenatal, perinatal, and childhood periods within a single study setting.
Lack of association between antibiotic use in the first year of life and asthma, allergic rhinitis, or eczema at age 5 years.
TLDR
The hypothesis that antibiotic use in early life is associated with the subsequent development of asthma and atopy in childhood is not supported.
Maternal infections in pregnancy and the development of asthma among offspring.
TLDR
The results suggest that further investigation of the relation of maternal infections during pregnancy to asthma among children seems warranted.
The importance of prenatal exposures on the development of allergic disease: a birth cohort study using the West Midlands General Practice Database.
TLDR
Investigating a birth cohort of 24,690 children, derived from the West Midlands General Practice Research Database, suggests exposure to antibiotics and to infections in utero is a potentially important risk factor in the development of allergic disease.

TLDR
The data suggest that the development of childhood asthma is associated with episodes of fever, antibiotic use, and acute gastroenteritis during infancy, as well as immunization during infancy.
