[Prevalence of Chlamydia trachomatis infection in infants & children]
Insights
Chlamydial infections are prevalent in Taiwanese children, particularly in infants under two years old. Early diagnosis and erythromycin treatment are effective for newborns with respiratory symptoms.
Area of Science:
- Pediatric Infectious Diseases
- Microbiology
- Ophthalmology
Context:
- Chlamydial infections pose a significant health concern in pediatric populations.
- Understanding the prevalence and transmission patterns is crucial for effective public health strategies.
- This study focuses on central Taiwan, providing regional epidemiological data.
Purpose:
- To determine the prevalence of Chlamydial infection in children in central Taiwan.
- To investigate the age-specific incidence and gender distribution of Chlamydial infections.
- To evaluate the effectiveness of erythromycin treatment in affected newborns.
Summary:
- A 10-month survey (Sept 1985-June 1986) in central Taiwan identified Chlamydial infections in 220 pediatric cases using enzyme immunoassay (EIA).
- Group A (newborns) showed a 12.2% antigen-positive rate, while Group B (pediatric ward with respiratory symptoms) had a 26.2% rate.
- Infection incidence was highest in children under two years old (77.2%), suggesting younger age correlates with higher positive rates, possibly indicating carrier status.
Impact:
- The findings highlight the high prevalence of Chlamydial infections in young children, emphasizing the need for targeted screening and prevention programs.
- Erythromycin ophthalmic ointment proved effective for neonatal conjunctivitis, while oral erythromycin is indicated for respiratory infections in newborns.
- This research contributes to the understanding of Chlamydial infection epidemiology in pediatric populations and informs treatment guidelines.
Abstract:
To understand the prevalence of Chlamydial infection in children in the central area of Taiwan, 220 cases were surveyed in the hospital nursery and pediatric ward from September 1985 to June 1986. In these 10 months, using the enzyme immunoassay (EIA) method, the patients were divided into two groups. Group A included 98 newborn cases, in the nursery, whose conjunctival secretions were collected within two hours after birth. All cases were then treated with erythromycin ophthalmic ointment. Group B included 122 cases, from the pediatric ward, who suffered from symptoms of respiratory tract disease; aspirated secretions from the trachea-were studied. The antigen positive rate in Group A was 12.2% (12 cases), male to female ratio was 1:5. However, in Group B the antigen positive ratio was 26.2% (32 cases), with male to female ratio of approximating 5:3. Children under two years old had the highest incidence of infection, around 77.2% (34 cases). In conclusion, the younger is the case, the higher the positive rate is. However, most of them probably are carriers. Newborns weighed more than 3 Kg and infants older than one month were not treated by erythromycin, but with supportive methods, the clinical symptoms and signs still improved gradually. However in newborn with symptoms of respiratory problem antibiotic treatment is usually indicated, and at present erythromycin is very effective.
