Ailevi Akdeniz Ateşli Hastalarda Gen Mutasyonu ile Klinik Bulgular Arasındaki İlişkilerin Değerlendirilmesi

Year 2013, Volume: 7 Issue: 4, 173 - 177, 01.12.2013

Abstract

Amaç: Ailevi Akdeniz Ateşi (AAA) tekrarlayan ateş ve peritonit ile karakterize bir hastalıktır. Hastalardaki klinik bulguların başlangıç yaşı ve hastalığın şiddeti mutasyon çeşidine göre farklılık gösterebilmektedir. Bu çalışmada MEFV genindeki mutasyonlar ile klinik bulguların ilişkisi araştırıldı. Hastalığın genotip/fenotip bağlantısı değerlendirildi.Gereç ve Yöntemler: Çalışmaya AAA tanılı 110 olgu alındı. İlk atak yaşı ve tanı yaşları belirlendi. Atak sırasındaki yakınmaları sorgulandı. MEFV gen mutasyonları belirlendi. Klinik yakınmalar ile mutasyon grupları ve mutasyonun tipi (homozigot/heterozigot/birleşik heterozigot) arasındaki ilişki araştırıldı.Bulgular: Hastalarda en sık M694V (%43.6), V726A (%13.6), E148Q (%10.9) mutasyonları saptandı. M694V/M680I heterozigot mutasyonu saptanan hastalarda göğüs ağrısı istatistiksel olarak anlamlı daha sıktı (p<0.001). Homozigot mutasyon ile artrit ve büyüme geriliği arasında anlamlı bir ilişki olduğu görüldü (p=0.049). Yakınmaların başlama yaşı (6.94±4.15 yıl) ile tanı yaşları (8.69±4.20 yıl) arasında anlamlı bir fark bulundu (p<0.0001). Tanı yaşındaki gecikme, mutasyonların homozigot/heterozigot olması veya çeşidi ile ilişkili değildi (p>0.05).Sonuç: AAA atağı sırasında görülen artrit, büyüme geriliği ve göğüs ağrısının mutasyon çeşidi ile ilişkili olduğu; başlangıç yaşının mutasyon çeşidi ile bir bağlantısı olmadığı düşünüldü.

Evaluation of the Relationship Between Mutation Type and Clinical Symptoms in Patients with Familial Mediterranean Fever

Year 2013, Volume: 7 Issue: 4, 173 - 177, 01.12.2013

Abstract

Objective: Familial Mediterranean Fever (FMF) is a disease characterized by recurrent fever and peritonitis. The onset of clinical symptoms and severity of disease in patients with FMF may be different according to the type of mutation. MEFV gene mutations and clinical symptoms were investigated in this study. The relationship between the genotype and phenotype of the disease was evaluated. Material and Methods: 110 patients diagnosed with FMF were included in this study. The first episode age and age at diagnosis were identified. The complaints during an attack were recorded. MEFV gene mutations were determined. The relationship between the type of mutation and mutations groups (homozygous/heterozygous/compound heterozygous) with clinical symptoms were investigated. results: The most common mutations were M694V (43.6%), followed by V726A (13.6%) and E148Q (10.9%). Chest pain was the most common clinical finding in patients with the M694V/M680I heterozygous mutation (p<0.01). There was a significant relationship between homozygous mutations and arthritis and growth retardation (p=0.049). There was also a significant difference between age of onset of symptoms and time of diagnosis (6.94±4.15 / 8.69±4.20 years, p<0.0001). Delay in diagnosis of FMF was not associated with mutation type and whether the mutation was homozygous or heterozygous (p>0.05). conclusion: We think that arthritis, growth retardation, and chest pain were associated with the type of mutation during attacks but the age of onset of symptoms was not associated with the type of mutation

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 7 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.
