Abstract

OBJECTIVE: We aimed to show the differences in flow-mediated dilatation (FMD) measurements between multiple sclerosis (MS) subgroups and normal control participants. MATERIAL AND METHODS: There were 96 participants (mean age: 42.7 ± 14.1 years) in this study. We grouped the participants as follows: 47 MS patients (mean age: 40.2 ± 12.2 years) and 49 normal control participants (mean age: 45.22 ± 15.27). The MS patients were subclassified as follows: Group 1 – relapsing-remitting multiple sclerosis (RRMS): 37 patients (mean age: 36.9 ± 11.2); Group 2 – secondary progressive multiple sclerosis (SPMS): 5 patients (mean age: 49.0 ± 6.0); and Group 3 – primary progressive multiple sclerosis (PPMS): 5 patients (mean age: 55.4 ± 10.6 years). We used FMD methods for an indirect evaluation of the brachial artery’s reaction to shear stress and peripheral vasodilatory nitric oxide (NO) production capability. RESULTS: There were statistically significant differences between the normal control group and the MS subgroups regarding flow-mediated basal, flow-mediated hyperemia, and FMD ratio values (p = 0.001, p = 0.029, and p = 0.020, respectively). No correlation was found between the expanded disability status scale (EDSS) scores and other measurements after statistically controlling for age and gender factors (p > 0.05). CONCLUSIONS: Our data indicate that FMD measurements decreased more in the MS patients compared to the normal controls. The PPMS group exhibited more severe deterioration with regard to FMD measures than the other groups. FMD ratio values decreased more in the progressive MS groups compared to the normal control and RRMS groups.

Özet

AMAÇ: Multiple skleroz (MS) alt grupları ile normal kontrol grubu arasındaki akıma bağlı dilatasyon (ABD) ölçümlerindeki farklılıkları göstermeyi amaçladık. GEREÇ VE YÖNTEM: Çalışmaya 96 katılımcı (ortalama yaş: 42,7 ± 14,1 yıl) alındı. Katılımcıları şu şekilde gruplandırdı: 47 MS hastası (ortalama yaş: 40,2 ± 12,2 yıl) ve 49 normal kontrol grubu (ortalama yaş: 45,22 ± 15,27). MS hastaları şu şekilde alt sınıflara ayrıldı: Grup 1 – Tekrarlayan ve düzelen MS (Relapsing-remitting) (RRMS): 37 hasta (ortalama yaş: 36,9 ± 11,2); Grup 2 – İkincil İlerleyici MS (Sekonder Progressif) (SPMS): 5 hasta (ortalama yaş: 49,0 ± 6,0); Grup 3 – Birincil İlerleyici MS (Primer Progressif) (PPMS): 5 hasta (ortalama yaş: 55,4 ± 10,6 yıl). Brakial arterin shear strese verdiği tepkiyi ve periferik vazodilatör nitrik oksit (NO) üretim kapasitesini akıma bağlı dilatasyon yöntemini kullanarak değerlendirdik. BULGULAR: Normal kontrol grubu ile MS alt grupları arasında akıma bağlı bazal, akıma bağlı hiperemi ve akıma bağlı bazal/hiperemi değerleri açısından istatistiksel olarak anlamlı farklar vardı (sırasıyla p = 0,001, p = 0,029 ve p = 0,020). Yaş ve cinsiyet faktörleri istatistiksel olarak kontrol edildiğinde, genişletilmiş özürlülük durumu ölçeği (EDSS) puanları ile diğer ölçümler arasında korelasyon bulunmadı (p > 0,05). SONUÇ: Verilerimiz MS hastalarında ABD ölçümlerinin normal kontrollere göre daha fazla azaldığını göstermektedir. Birincil İlerleyici MS grubu, diğer gruplara kıyasla ABD ölçümleri açısından daha şiddetli bozulma gösterdi. ABD bazal/hiperemi oranı değerleri, normal kontrol ve tekrarlayan ve düzelen MS gruplarına kıyasla ilerleyici MS gruplarında daha fazla azaldı.
