Abstract

Objective: The aim of our study was to investigate the association of HLA antigens and a non-HLA protein D8/17 with rheumatic heart disease and its pattern of cardiac involvement.Methods: This cross- sectional observational study included 35 children and 12 adult patients who have rheumatic heart disease and 35 healthy children and 12 healthy adult controls. After physical examination, all patients and control group members were evaluated with 2D and color-coded echocardiography. B- lymphocyte D8/17 expression was tested by a flow cytometry assay. HLA genotyping was performed using polymerase chain reaction sequence-specific primers. In statistical analysis, Chi-square, unpaired t and Mann-Whitney U tests were used for comparison groups.Results: The percentage of the D8/17-expressing B lymphocytes of the patient group was significantly higher than of the control group (77.3±15.6% vs. 67.7±20.0%, p=0.013). When compared with the control group, the HLA DRB5 (38.6% vs. 13.6%, p=0.007) and HLA DRB1*15 (31.8% vs. 9.0%, p=0.008) expression levels of the patient group were significantly higher and the DRB4 expression of the patient group was significantly lower (29.5% vs. 50.0%, p=0.049).Conclusion: Our findings support the association between HLA Class 2 subgroups and rheumatic heart disease, and an association between D8/17 expression and rheumatic heart disease. Further studies including higher number of patients and control group members should be performed for the confirmation of our results.

Özet

Amaç: Bu çalışmanın amacı, romatizmal kalp hastalığı olan hastalarda HLA-DR subgrupları ve HLA dışı B lenfosit belirteci olan D8/17 belirteç oranlarını araştırmaktı. Yöntemler: Bu enine-kesitli gözlemsel çalışmaya romatizmal kalp hastalığı olan 35 çocuk ve erişkin hasta ile kontrol grubu olarak sağlıklı 35 çocuk ile sağlıklı 12 erişkin alınmıştır. Hasta ve kontrol grubunda yer alan bireyler renkli Doppler ve 2 boyutlu ekokardiyografi ile değerlendirildikten sonra D8/17 B lenfosit markeri ve HLA-DR subgrupları için kan örnekleri alındı. B lenfosit D8/17 ekspresyonu akım sitometrisi kullanılarak değerlendirildi. HLA-DR subgupları ise ilgili primerler kullanılarak PCR yöntemi ile değerlendirildi. İstatistiksel analiz için gruplar arası karşılaştırmada Ki-kare, eşleştirilmemiş t ve Mann-Whitney U testleri ile değerlendirildi.Bulgular: D8/17 eksprese eden B lenfosit yüzdesi hasta grubunda kontrol grubuna göre istatistiksel olarak anlamlı olarak yüksek bulundu (%77.3±15.6’ ya karşın %67.7±20.0, p=0.013). HLA DRB5 (%37.6’ya karşın %13.6, p=0.007) ve HLA DRB1*15 (%31.8’e karşın %9.0, p=0.008) ekspresyonu hasta grubunda anlamlı olarak yüksek bulunurken, DRB4 ekspresyonu (%29.5’e karşın %50.0, p=0.049) kontrol grubunda hasta grubuna göre anlamlı olarak yüksek bulundu.Sonuç: Çalışmamızda HLA DR subgrupları ve D8/17 ekspresyonu romatizmal kalp hastalığı ile arasında ilişki bulunduğunu desteklemektedir. Sonuçlarımızın desteklenmesi daha fazla çalışmaya ihtiyaç vardır.
