title: Effect of zinc supplement in the prognosis of burn patients in iraq.
abstract: Many studies have reported that zinc plasma levels significantly decrease after a burn, leading to zinc deficiency, and that increased free radical generation and decreased natural antioxidant may negatively affect wound healing and burn outcome in general. Targeting of these changes is considered an important strategy in the treatment of burns in an attempt to improve burn outcome in the clinical setting. Zinc was given orally in a nutritional dose (15 mg elemental zinc) as a zinc sulphate capsule to burn patients in order to improve post-burn zinc deficiency and burn outcome. The study was carried out in 58 burn patients of different age groups, sex, and occupation with different burn size. The patients were allocated to two groups: group A patients (43 in number) were treated with topical povidone-iodine ointment for the first four days post-injury followed by topical silver sulphadiazine cream 1% until discharge in addition to other prescribed drugs according to our burn unit policy; group B patients (15) received the same treatment as group A plus a single daily oral dose of zinc sulphate in a 66 mg capsule, equivalent to 15 mg elemental zinc. In each group, using standard methods, we considered plasma zinc and copper levels, oxidative stress parameters, thyroid, liver, and renal function tests, microbiological factors, mortality rate, healing time, and cost effectiveness. The administration of zinc in dietary doses significantly increased the plasma zinc level in burn patients to around normal control levels and improved the antioxidant status, as represented by elevation of the natural antioxidant level (glutathione), in addition to improving healing time, the incidence of eschar formation, and the mortality rate, compared with the zinc-nonsupplemented group. We conclude that dietary zinc supplementation in zinc-deficient burn patients led to great improvements in their outcome and that zinc deficiency was as an important goal to target during treatment; also, that the use of a combination of topical and systemic antioxidants (povidoneiodine ointment and zinc sulphate, respectively) represented a good strategy for improving results in burn patient treatment.
