In vivo analysis of the apoptosis‐inducing effect of anti–endothelial cell antibodies in systemic sclerosis by the chorionallantoic membrane assay

Abstract: Conclusion. This study is the first to demonstrate the in vivo apoptosis-inducing effects of AECAs. The findings support our hypothesis of a primary pathogenetic role of AECAs in SSc.

“…Increased endothelial apoptosis was shown to represent the earliest microvascular abnormality in an animal model of systemic sclerosis and to precede fibrotic changes (5). Anti-EC Abs, found in a majority of sclerodermic patients, are known to induce EC apoptosis both in vitro (6) and in vivo (7). Studies in early inflammatory human sclerodermic lesions have also supported the contention that endothelial apoptosis is an initial triggering phenomenon in systemic sclerosis (5).…”

“…Известно, что некоторые аутоантитела при ССД имеют патологическую активность в отношении соб-ственных тканей in vitro. Так, антиэндотелиальные аутоан-титела могут вызвать апоптоз эндотелиальных клеток, ан-титела к фибрилларину 1 вызывают активацию фибробла-стов и усиливают продукцию экстрацеллюлярного матрик-са, антитела к фибробластам усиливают синтез ИЛ6 и экс-прессию ICAM и т. д. Установлены отчетливые корреляции между профилем аутоантител и некоторыми клинически-ми проявлениями заболеваний, хотя точная их роль при ССД остается нерасшифрованной [1,5,59]. Интересно, что у больных ССД при деплеции В-клеток под действием ритуксимаба уменьшение кожного фиброза происходило параллельно снижению концентрации ИЛ6 в крови [60], что косвенно свидетельствует о роли ИЛ6 в фиброзирую-щем процессе.…”

“…Средний возраст больных составил 58 (46)(47)(48)(49)(50)(51)(52)(53)(54)(55)(56)(57)(58)(59)(60)(61) лет. Исходно 73% больных получали низкие дозы ГК (≤10 мг/сут в пересчете на преднизолон) и 57% -метотре-ксат.…”

“…Increased permeability of the nail fold capillaries (Bollinger, Jager, & Siegenthaler, 1986) and increased endothelial apoptosis (Sgonc et al, 1996)have been described in SSc patients. Endothelial cell injury in SSc may be triggered by anti-endothelial antibody (Worda et al, 2003), cytokines (Kahaleh, 2004), complement abnormalities (Venneker, van den Hoogen, Boerbooms, Bos, & Asghar, 1994) and/or cellular cytotoxicity . Scleroderma renal crisis (SRC) can complicate the course of up to 10-20% of patients with SSc.…”
