Abstract

Amaç: Varisella, özellikle küçük çocuklarda potansiyel olarak ciddi komplikasyonları olan oldukça bulaşıcı bir hastalıktır. Türkiye’de su çiçeği aşısı, 2013 yılında 12 aylık bebekleri hedef alan Ulusal Suçiçeği Aşısı programına entegre edildi. Resmi olarak rapor edilen su çiçeği vakaları son yirmi yılda önemli ölçüde azalmış olsa da, eksik raporlama hala bir sorun olmaya devam ediyor. Bu çalışmada üçüncü basamak bir merkezde suçiçeği seropozitifliğinin araştırılması amaçlanmıştır.

Gereç ve Yöntemler: Kalitatif bir immünolojik test olan enzim bağlantılı immünosorbent testi (ELISA), anti-varisella antikorlarını tespit etmek için kullanılmıştır. Türkiye’de ikamet eden 4-18 yaş arası bireylerden serum örnekleri toplandı. Aşı kayıtları, su çiçeği geçmişi ve hastalık bildirimine ilişkin bilgiler de toplanmıştır.

Bulgular: Toplam 90 çocuğun su çiçeği IgG antikoru kayıtlarına erişildi. Çalışma popülasyonunda pozitif su çiçeği antikorlarının genel prevalansı %58.0 (n=47)’di. Seropozitiflik oranları 4-6 yaş grubunda %67.2, 7-12 yaş grubunda ise %30 olarak belirlendi. Özellikle 4-6 yaş grubu seropozitiflik ile yaş arasında anlamlı bir ilişki gösterdi [p=0.005; OR=4.85; 95%CI (1.614-14.569)].

Sonuç: Suçiçeği için %58’lik seropozitiflik oranı endişe vericidir. Bunun ışığında daha kapsamlı çalışmaların yapılması değerli bir yol gösterici olacaktır. 4-6 yaş aralığında ek doz su çiçeği aşısı yapılması düşünülebilir. Böyle bir aşılama stratejisinin uygulanmasının potansiyel faydalarını ve fizibilitesini değerlendirmek için daha fazla araştırma yapılması gerekmektedir.

Varicella Seroprevalence in Pediatric Populations: Results from a Single-Center Study

Year 2024, Volume: 18 Issue: 3, 192 - 195, 13.05.2024

Abstract

Objective: Varicella is a highly contagious illness with potentially severe complications, especially in young children. In Turkey, the varicella vaccine was integrated into the Universal Varicella Vaccination program in 2013, targeting 12-month-old infants. While officially reported varicella cases have decreased considerably in the past two decades, underreporting remains a challenge. This study aimed to investigate varicella seropositivity in a tertiary center.

Material and Methods: A qualitative immunoassay, the enzyme-linked immunosorbent assay (ELISA), was employed to detect anti-varicella antibodies. Serum samples were collected from individuals aged 4 to 18 residing in Turkey. Information on vaccination records, varicella history, and disease notification was also collected.

Results: The varicella IgG antibody records were accessed for a total of 90 children. The overall prevalence of positive varicella antibodies was 58.0% (n=47) in the study population. Seropositivity rates were 67.2% for the 4-6 age group and 30% for the 7-12 age group. Notably, the 4-6 age group showed a significant association between seropositivity and age [p=0.005; OR=4.85; 95%CI (1.614-14.569)].

Conclusion: The seropositivity rate of 58% for chickenpox is concerning. In light of this, conducting more extensive studies will provide valuable guidance. It may be worth considering the administration of an additional dose of the varicella vaccine within the age range of 4-6 years. Further research is necessary to assess the potential benefits and feasibility of implementing such a vaccination strategy.

The publication language of Turkish Journal of Pediatric Disease is English.


Manuscripts submitted to the Turkish Journal of Pediatric Disease will go through a double-blind peer-review process. Each submission will be reviewed by at least two external, independent peer reviewers who are experts in the field, in order to ensure an unbiased evaluation process. The editorial board will invite an external and independent editor to manage the evaluation processes of manuscripts submitted by editors or by the editorial board members of the journal. The Editor in Chief is the final authority in the decision-making process for all submissions. Articles accepted for publication in the Turkish Journal of Pediatrics are put in the order of publication, with at least 6 original articles in each issue, taking into account the acceptance dates. If the articles sent to the reviewers for evaluation are assessed as a senior for publication by the reviewers, the section editor and the editor considering all aspects (originality, high scientific quality and citation potential), it receives publication priority in addition to the articles assigned for the next issue.


The aim of the Turkish Journal of Pediatrics is to publish high-quality original research articles that will contribute to the international literature in the field of general pediatric health and diseases and its sub-branches. It also publishes editorial opinions, letters to the editor, reviews, case reports, book reviews, comments on previously published articles, meeting and conference proceedings, announcements, and biography. In addition to the field of child health and diseases, the journal also includes articles prepared in fields such as surgery, dentistry, public health, nutrition and dietetics, social services, human genetics, basic sciences, psychology, psychiatry, educational sciences, sociology and nursing, provided that they are related to this field. can be published.
