Insights into the poor prognosis of allopurinol-induced severe cutaneous adverse reactions: the impact of renal insufficiency, high plasma levels of oxypurinol and granulysin

Abstract: Impaired renal function and increased plasma levels of oxypurinol and granulysin correlated with the poor prognosis of allopurinol-SCAR. Allopurinol prescription is suggested to be avoided in subjects with renal insufficiency and HLA-B*58:01 carriers. An early intervention to increase the clearance of plasma oxypurinol may improve the prognosis of allopurinol-SCAR.

“…In accordance with updated treatment guidelines for hyperuricemia and the pattern of ULA use in the real-world setting, the treatment strategies evaluated in our present study included (1) genetic screening prior to allopurinol prescribing, (2) prescribing benzbromarone without screening, (3) prescribing febuxostat without screening, and (4) prescribing allopurinol without screening. Table 1 presents variables used in the model 8,9,11,22,23,24,25,26,27 .…”

“…A plausible mechanism for this is that the oxypurinol metabolite accumulates in patients with impaired renal function 11 so that the risk of allopurinol hypersensitivity is increased by 4-5× in patients with CKD treated with allopurinol (OR 4.7, 95% CI 2.3-9.3) 11 .…”

“…97 Indeed, it is now known that elevated serum oxypurinol concentration is an important risk factor for allopurinol IM-ADR. 99 The half-life of orally administered allopurinol is only 1-2 hours while the half-life of oxypurinol is 15 hours in the setting of normal renal function, longer in the setting of renal insufficiency. Importantly, both impaired renal function and increased plasma concentrations of oxypurinol and granulysin, a known mediator of tissue injury in SJS/TEN, have been shown to correlate with disease severity and mortality in allopurinol-SJS/TEN/DRESS, demonstrating the dose-dependency of these responses.…”

“…Основанием для его выделения являются данные об увеличении риска развития тяжелых аллергиче-ских реакций в рамках синдрома гиперчувствительности к аллопуринолу, вероятность которого увеличивается при сниженной почечной функции, что служит основанием для индивидуального вычисления допустимой дозы препа-рата в зависимости от СКФ [111][112][113][114]. Развитие таких ре-акций происходит редко, может быть связано с носитель-ством гена HLA В5801*, встречающегося преимущественно в популяциях стран Азии (Корея, Тайвань и др.…”

“…Развитие таких ре-акций происходит редко, может быть связано с носитель-ством гена HLA В5801*, встречающегося преимущественно в популяциях стран Азии (Корея, Тайвань и др. ), однако высокий уровень смертности при их развитии требует строгого контроля за применением препарата в случае на-личия факторов риска [113][114][115]. Однако есть исследова-ния, ставящие под сомнение необходимость лимитирова-ния дозы аллопуринола при почечной недостаточности.…”
