| الوصف: | Background: The role of the alternative complement pathway (AP) abnormalities in the pathogenesis of aHUS is well studied. Clinical and morphological manifestations of atypical HUS and catastrophic APS are often similar. However, studies on the state of AP in patients with CAPS are virtually absent. Aims: The aim of our study was to assess the state of AP in patients with CAPS and aHUS. Patients and methods: The study enrolled 67 patients (pts) with a diagnosis of CAPS (28 pts) and aHUS (39 pts). Studies of the complement system are made of 10 pts with CAPS and 20 aHUS. Factor H, I, B, D content, functional activity of factor H, and complement components C3, C4 was determined in serum by ELISA kit. Results: Patients with CAPS and aHUS showed similar changes in complement biomarkers. The factor H level in the serum was significantly higher than the standard value. However, the specific activity of factor H reduced, mean rate 59% for aHUS and 26% for CAPS. The median value of factor D was twice higher than the normal range in both groups, indicating the activation of the AP. Conclusions: There are indications of an AP activation not only in pts with aHUS but in CAPS pts too. We suppose that the activity of factor H is a more sensitive indicator of complement system changes than factor H level. Patients with CAPS and aHUS have similar clinical and laboratory characteristics. However, CAPS is more severe, with the involvement of a larger number of vascular beds. Perhaps this is due to the double damaging effects on the endothelium ― of antiphospholipid antibodies (aPL) and activated complement. So we hypothesize that CAPS can be called aPL-mediated TMA in pts with a complement system defect. ; Обоснование: Клиническая картина как аГУС, так и КАФС обусловлена развитием тромботической микроангиопатии. Роль комплемента в патогенезе аГУС известна, а вклад патологии комплемента в развитие КАФС не достаточно изучен.Цель исследования: изучить изменения в системе комплемента у пациентов с КАФС в сравнении с таковыми при ... |
