Case report of atypical hemolytic uremic syndrome with retinal arterial and venous occlusion treated with eculizumab

Abstract: Atypical hemolytic uremic syndrome (aHUS) is a rare disease caused by chronic, uncontrolled activation of the alternative complement pathway, leading to thrombotic microangiopathy. Renal impairment and progression to end-stage renal disease are common in untreated patients with aHUS, and extrarenal manifestations are being increasingly characterized in the literature. Ocular involvement remains rare in aHUS. This report describes a patient with aHUS with bilateral central retinal artery and vein occlusion, vit… Show more

“…A recent paper by Zhang et al suggests that the leading factor in the pathogenesis of microcircular damage in COVID-19 patients is complement-mediated thrombotic microangiopathy (TMA) [ 30 ]. Complement system activation has been previously described as directly responsible of ocular vascular damage, with rare cases of atypical hemolytic uremic syndrome, leading to retinal artery and vein occlusions [ 31 ]. It is also worthy of consideration that high serum levels of C3 complement factor have also been linked to increased risk of developing diabetic retinopathy, nephropathy, and neuropathy, via endothelial dysfunction and thrombosis [ 32 ].…”

“…Выявленные при офтальмоскопии билатеральные изменения в виде ППР (отек и монотонность ДЗН, интраретинальные кровоизлияния и мягкие экссудаты, являющиеся маркерами ишемии внутренних слоев сетчатки, отек в макулярной области сетчатки), а также признаки ангиосклероза сетчатки с симптомом артериовенозного перекреста Салюса-Гунна II-III степени свидетельствовали о вероятном остром нарушении кровообращения в сосудах микроциркуляторного русла сетчатки и зрительного нерва на фоне хронической злокачественной гипертензии. Результаты представленного наблюдения согласуются с данными других исследований, в которых авторы чаще описывают билатеральную ППР как проявление поражения органа зрения при аГУС [9][10][11][12]15]. Наши предположения о тромботической природе офтальмоскопических изменений подтвердили результаты ОКТ, где были выявлены признаки посттромботической ангиоретинопатии.…”

“…Повреждение органа зрения является редким проявлением этого заболевания [9,11]. В литературе приводятся описания преимущественно единичных случаев поражения глаза при аГУС [9][10][11][12][13][14][15]. В ретроспективном исследовании E. Phillips и соавторы сообщают о зрительных нарушениях у 7% пациентов [4].…”
