Resumo
Trata-se de um trabalho do tipo coorte para avaliar a espoliação dos depósitos de ferro em doadores de sangue. Sabendo-se que um percentual expressivo da população brasileira é portadora de ferro deficiência, e tendo em vista as inovações tecnológicas envolvendo os processos hemoterápicos este projeto teve como objetivo a avaliação da dinâmica de ferro com o monitoramento de parâmetros tais como: hematócrito, hemoglobina, dosagem de ferro e ferritina pré transfusionais e quatro meses após a doação, em quatro diferentes grupos de estudo:A,C,Ce D. Foi feita pelo teste ANOVA simples e para as variáveis sem distribuição normal pelo teste não paramétrico de Mann-Whitney e o teste de Kruskal Wallis, teste T-Pareado e Wilcoxon. No primeiro momento de análise (M1), com análise intra-grupos, as variações estatísticas foram presentes apenas nos parâmetros de Hb (p. 0,017), onde as variações estiveram presentes quando comparados os grupos A x D (p. 0,034) e C x D (p. 0,028) e Ht (p. <0,01) onde as variações estiveram presentes quando comparados os grupos A x D (p. 0,034) e C x D (p. 0,028). No segundo momento de análise (M2) foi identificada diferença entre os grupos, entretanto, devido à baixa significância estatística não foi possível identificar a diferença exata por grupo. Quando comparado entre os momentos um e dois- (M1 x M2) foi identificado redução da média de todos os parâmetros para os grupos A, B e C, significância estatística para o parâmetro de hemoglobina para todos os grupos e significância para o parâmetro de Ferritina exceto para o grupo B, sendo esse o único que demonstrou otimização na melhoria dos parâmetros exceto a hemoglobina. A doação de sangue diminui os índices de hemoglobina nos doadores de sangue a curto e médio prazo quando comparados em dois momentos com 4 meses de intervalo; para o indicador hematócrito e determinação de ferro sérico houve diminuição dos índices com significância estatística apenas para o grupo A (indivíduos que nunca haviam doado antes); quanto à sugestão na periodicidade das doações de CHD utilizando a modalidade de coleta aférese, o intervalo de 4 meses é insuficiente. Sugere-se 6 meses com a condição de se comprovar a viabilidade.
It is a work of the cohort to evaluate the plundering of iron deposits in blood donors. Knowing that a significant percentage of the population is disabled iron, and in view of the technological innovations involving haemotherapic processes this project aimed to evaluate the iron dynamics with the monitoring of parameters such as hematocrit, hemoglobin, iron dosing and pre transfusion ferritin months after the donation, in four different study groups: A, B, C and D. Statistical analyses was made by ANOVA and simple test for variables without normal distribution using the nonparametric Mann-Whitney and Kruskal Wallis test, Paired t-test and Wilcoxon. At first analysis (M1) and intra-group analysis, statistical variations were present only in Hb parameters (p. 0.017), where variations were present when comparing the x groups D (p. 0.034) and C x D (p. 0028) and HT (p. <0.01) in which variations were present when comparing the groups D x (p. 0.034) and C x D (p. 0028). In the second stage of analysis (M2) was identified differences between the groups, however, due to the low statistical significance was not possible to identify the exact difference per group. When compared between one and two- moments (M1 and M2) was identified reduction in the average of all parameters for groups A, B and C for the statistical significance hemoglobin parameter for all groups and significance for the parameter Ferritin except for the B group, which is the only one that showed improvement in optimization of parameters except hemoglobin. Blood donation decreases hemoglobin levels in the short and medium term blood donors when compared in two stages with 4 months apart; for the indicator hematocrit and determination of serum iron there was a decrease of the indices was statistically significant only for the group A (individuals who had never donated before); as the suggestion in the frequency of Double erythrocyte concentrate donations using the method of apheresis collection, four months range is insufficient. It is suggested that 6 months with the condition to prove the viability.
