“…8-isoprostane has a short half-life, being metabolized to 2,3-dinor-8-iso-PGF 2α and 2,3-dinor-5,6-dihydro-8-iso-PGF 2α , among others (reviewed in [12]). In sera from LL patients, higher levels of 2,3-dinor-8-iso-PGF 2α , but not of 8-isoprostane, were observed (Table 2), which could be linked to the higher oxidative stress and lower antioxidant capacity observed in leprosy, more specifically in patients with the lepromatous form [15], [16].…”

“…It could catalyze the degradation of H 2 O 2 directly to water and prevent the secondary generation of other intermediate radicals. In addition, selenium-containing glutathione peroxidase (GPx) could also catalyze the reduction of H 2 O 2 [ 50 ]. This reaction needs reduced glutathione (GSH) as cosubstrate and GSH will be oxidized to oxidized glutathione (GSSG).…”

“…Além disso, a literatura demostra aumento de estresse oxidativo, depleção antioxidante e de micronutrientes na hanseníase [7][8][9][10][11] . Contudo, os mecanismos que explicam tais alterações permanecem obscuros, e associá-los à causa ou consequência da doença pode contribuir de forma significativa para o diagnóstico preciso e precoce, tratamento, reabilitação e manejo da doença como um todo.…”

“…Prasad et al 11 verificaram níveis reduzidos de GSH no sangue de pacientes com a doença em relação ao grupo controle, exceto para as formas tuberculoide e dimorfa tuberculoide, ou seja, formas paucibacilares. No presente estudo, o resultado foi semelhante, uma vez que o grupo paucibacilares apresentou GSH estaticamente igual ao de indivíduos saudáveis, enquanto, no grupo multibacilares, a GSH foi deficiente e poderia estar associada ao perfil de suscetibilidade dos multibacilares diante da hanseníase (baixa resistência e alta disseminação dos bacilos).…”
