Uso de hierro intravenoso en pacientes renales crónicos con anemia. Mayores niveles de hemoglobina a más bajo costo / Use of intravenous iron in chronic renal patients with anemia. Higher levels of hemoglobin at a lower cost

It is presented the experience with 90 patients receiving Eritropoietin s.c. and oral iron who were in chronic haemodialysis. After basic laboratories, including iron kinetic, in all of them was stopped oral iron and started i.v. iron 60 mgs per week, but keeping the same eritropoietin doses. The results showed an increased haemoglobin level from 6.5 to 11 g/dl mean values and a decreased doses of eritropoietin between 25 to 50%. This represent an important elevation of haemoglobin levels at a significant low cost

Uso de eritropoyetina en pacientes con insuficiencia renal crónica y en hemodiálisis / Use of erythropoietin in patients with chronic renal insufficiency and in hemodialysis

Erythropoietin (EP) injected subcutaneously (SC) 2 or 3 times a week, respectively, or intravenously (IV) 3 times a week, increased the hemoglobin and the hematocrit of all the patients so treated. The total units of EP used was less when it was administered SC. EP once or twice a week, respectively, administered SC also increased the hemoglobin and hematocrit in each case, and the total amount of EP used was also less

Frecuencia de genes y haplotipos del sistema HLA en la poblacion Panameña / Gene frequency and haplotypes of the HLA system in the Panamanian population

The authors determined the frequency of genes and haplotypes of the HLA system in 965 panamanian men and women not related to each other, between 6 and 65 years of age. The HLA-A locus genes with the highest frequency (f) were A2, with f 0.1763; A24, f 0.1584; A30, f 0.1340; A23, f 0.1069; A3, f 0.0774. The other 20 genes each had less than 0.07. The genes with the highest frequency for locus HLA-B were B35, f 0.1946; B44, f 0.0904; B7, f 0.0774; B60 and B61, f 0.0582. For locus HLA-C, the most frequent genes were Cw3 with f 0.1549 and Cw4, f 0.1444. For locus HLA-DR, the most frequent genes were DR2 with f 0.1283; DR3, f 0.0620; DR7, f 0.0409. The most frequent haplotypes in the panamanian population were A2-B35 with f 0.0382; A3-B35, f 0.0191; A24-35, f 0.0287; A24-B61, f 0.0239; A29-B44, f 0.0287; A30-B42, f 0.0239; A23-B44, f 0.0191; A1-B8, f 0.0143. The authors conclude that the panamanian population exhibits a high degree of polymorphism for loci HLA-A, B and C, while for locu HLA-DR the frequency is the median when compared with that in caucasian, negro and oriental groups; and that, according to locus, predominant genes originating from these groups and found, corroborating the multiracial origen of the panamanian population
