Résumé

O objetivo desse estudo foi avaliar a eficácia do uso intravenoso de sacarato de hidróxido de ferro III no tratamento de pacientes adultos com anemia ferropriva. No período de janeiro de 2003 a dezembro de 2005, estudamos cinqüenta pacientes com anemia ferropriva que apresentaram intolerância e/ou resposta inadequada ao tratamento com ferro por via oral e/ou valor de hemoglobina inferior a 7,0 g/dL. Os principais exames laboratoriais realizados foram: hemograma completo, contagem de reticulócitos, ferro sérico, capacidade total de ligação de ferro e ferritina sérica. Os pacientes receberam uma dose semanal de 200 mg de sacarato de hidróxido de ferro III diluído em 250 mL de soro fisiológico a 0,9 por cento, administrado por via intravenosa em trinta minutos. O tratamento foi realizado até a obtenção do valor de hemoglobina igual ou maior que 12,0 g/dL para mulheres e 13,0 g/dL para homens, ou até a administração da dose total de ferro parenteral recomendada para cada paciente. A idade mediana dos cinqüenta pacientes estudados foi de 45 anos, variando entre 28 e 76 anos; quarenta (80,0 por cento) eram do sexo feminino. A causa mais comum de anemia ferropriva no sexo feminino foi sangramento uterino anormal observado em 25/40 pacientes (62,5 por cento) e, no sexo masculino, gastrectomia parcial em 7/10 (70,0 por cento). Vinte e quatro (48,0 por cento) pacientes foram incluídos nesse estudo por falta de resposta à terapia com ferro oral, 22 (44,0 por cento) por intolerância ao ferro oral e quatro (8,0 por cento) por hemoglobina < 7,0 g/dL. Os valores médios da hemoglobina e da ferritina sérica foram de 8,48 g/dL e 4,65 ng/mL (pré-tratamento) e 12,34 g/dL e 93,20 ng/mL (pós-tratamento)(p<0,001), respectivamente. O aumento médio de hemoglobina foi de 3,61 g/dL e de 4,83 g/dL para os sexos feminino e masculino, respectivamente. Correção da anemia foi obtida em 26 (65,0 por cento) das quarenta pacientes do sexo feminino e em nove (90,0 por cento)...


The objective of this study was to evaluate the efficacy of intravenous iron III-hydroxide saccharate to treat adult patients with iron deficiency anemia. Between January 2003 and December 2005 we studied 50 patients with iron deficiency anemia who presented intolerance or inadequate response to oral iron therapy, or hemoglobin level < 7 g/dL. The main laboratory tests performed were: complete blood cell count, reticulocyte count, serum iron, total iron-binding capacity and serum ferritin. The patients received a weekly dose of 200 mg of iron diluted in 250 mL of 0.9 percent sodium chloride solution administered intravenously during 30 minutes. It was performed until a hemoglobin level = 12.0 g/dL for women or13.0 g/dL for men was reached or completing the administration of the total dose of parenteral iron recommended for each patient. The median age of the patients studied was 45 years (age range from 18 to 76). Forty out of 25 patients (80 percent) were women. The most common cause of iron deficiency anemia was abnormal uterine bleeding observed in 62.5 percent of female patients (25 out of 40) and partial gastrectomy in 70 percent of male patients (7 out of 10). Twenty-four (48 percent) patients were included in this study due to a lack of response to oral iron therapy, 22 (44 percent) showed intolerance to oral iron and 2 (8 percent) presented with a hemoglobin level < 7.0 g/dL. The mean hemoglobin and ferritin values were 8.48 g/dL and 4.65 ng/mL (pretreatment) and 12.34 g/dL and 93.20 ng/mL (post-treatment) (p<0.001), respectively. The average increase of hemoglobin was 3.61 g/dL and 4.83 gdL for women and men, respectively. Correction of anemia was obtained in 26 out of 40 female patients (65 percent) and in 9 out of 10 male patients (90 percent). Six patients received blood transfusions before starting intravenous iron treatment. None of the 50 studied patients needed red blood cell transfusions during or after completing...

Résumé

Anemia is a frequent complication of CKD and has numerous physiologic effects. In the treatment of anemia it is important to guarantee adequate iron storesfor hemoglobin synthesis. The aim of this study is to report on the impact of iron reposition on hemoglobin levels in patients with CKD stages 3 to 5. Fortyanemic patients (hemoglobin <11.0 g/dL) with CKD stages 3 (17,5%), 4 (58,5%), and 5 (25%), not receiving re-Hu-Erithropoetin were treated with IV iron(Noripurum, Altana Pharma), a ferric sucrose product. Iron deficiency was diagnosed when transferrin saturation was <20% and/or ferritin <100 mg/L. TheIV Iron (100 mg/ ampoules) was given in 150 mL of saline over 90 minutes. Glomerular filtration rate (GFR) was estimated from serum creatinine using theMDRD formula, and patients were categorized according to the stages defined by K/DOQI of the NKF. The mean age of the patients was 58.6±17 yearsand 56% were female. The main causes of CKD were hypertension (33.0%), diabetes mellitus (19.0%) and glomerulonephritis (19.0%). The mean valuesof the lab results before and after the IV iron administration were: creatinine (2.79±1.28 and 3.01±1.84, p>0.90), GFR (25.92±13.4 and 26.14±13.34, p>0.29), serum iron (58.3±28 and 90.9, p>0.60), transferrin saturation index (22.94±11.36 and 27.4±8, p>0.49), ferritin (84.69±78.3 and 164.8±141, p<0.04) andhemoglobin (9.52±1.24 and 10.53±1.44, p<0.000). The mean amount of IV iron sucrose administered was 319±180mg. The IV iron was very well toleratedand no serious side effect was observed. In conclusion, administration of IV Noripurum, a dextran-free iron compound, was safe and showed a beneficial impact on the hemoglobin level, and its use optimized the treatment of anemia in patients with CKD.


A anemia é uma complicação freqüente na doença renal crônica (DRC) e determina vários efeitos fisiológicos. No tratamento da anemia, é importantegarantir a reserva de ferro adequada para a síntese de hemoglobina. O objetivo deste trabalho é relatar sobre o impacto da reposição de ferro nos níveisde hemoglobina em pacientes com anemia decorrente da DRC na fase pré-dialítica. Quarenta pacientes anêmicos (hemoglobina <11,0g/dL) com DRCestágios 3 (17,5%), 4 (58,5%) e 5 (25%), não tratados com eritropoetinina humana recombinante, receberam ferro venoso (sacarato de hidróxido de ferroIII, Noripurum, ALTANA Pharma). A deficiência de ferro foi diagnosticada quando o índice de saturação da transferrina (%) foi inferior <20%, associado ounão à ferritina (mg/dL) <100mg/dL. O ferro endovenoso foi administrado na dose de 100mg diluído em 150mL de soro fisiológico no período de 90 minutos.A filtração glomerular (mL/min/1,73m2) foi estimada a partir da creatinina sérica (mg/dL) através da fórmula do estudo MDRD e os pacientes foramestagiados segundo as diretrizes brasileiras sobre DRC e o K/DOQI da National Kidney Foundation. A idade média dos pacientes foi de 58,6 ±17 anos,sendo 56% do sexo feminino. As principais causas de DRC foram hipertensão arterial (33,0%), diabetes mellitus (19,0%) e glomerulonefrites (19,0%). Osvalores médios dos resultados laboratoriais antes da reposição de ferro e após foram: creatinina (2,79±1,28mg/dL e 3,02±1,84mg/dL, p= 0,90), FG(25,92±13,4mL/min/1,73m2 e 26,14±13,34mLmin/1,73m2, p= 0,29), ferro sérico (58,3±28 e 90,9±35, p= 0,60), índice de saturação da transferrina(22,94±11,36% e 27,40±8,0, p= 0,49), ferritina (84,69±78,3 e 164,8±13,34, p<0,004) e hemoglobina (9,52±1,24g/dL e 10,53±1,44, p<0000). A quantidademédia de sacarato de hidróxido de ferro III administrada foi de 319±178mg.
