A doença hemolítica perinatal (DHPN) ainda é um problema clínico. Nenhum teste isolado prediz, com segurança, a gravidade do quadro hemolítico. O objetivo do presente estudo foi determinar as subclasses de anticorpos IgG1 e IgG3 por citometria de fluxo no soro de 42 gestantes isoimunizadas e correlacionar os dados obtidos com a gravidade da DHPN. A distribuição dos fetos ou neonatos segundo a gravidade do quadro hemolítico evidenciou 13 casos com doença leve, 16 casos com doença moderada e 13 com doença grave. As subclasses foram detectadas em 33/42 (79%) amostras. A subclasse IgG1, isoladamente, foi evidenciada em 14/33 (42,4%) casos. Na relação entre gravidade da doença e subclasses de IgG, observou-se que IgG1 isolada foi encontrada em todos os grupos, e os valores da mediana de intensidade de fluorescência (MIF) foram significativamente mais altos nas formas mais graves da DHPN (p<0,01). Contrariamente, os valores da MIF para IgG3 se apresentaram mais homogêneos em todas as categorias (p=0,11). A presença de IgG3 parece, portanto, estar mais associada à hemólise leve. A associação das subclasses IgG1 e IgG3 está relacionada à situação clínica mais grave, o que se deve, possivelmente, à presença de IgG1 associada. Apesar dos altos valores para IgG1 e a associação de IgG1 com IgG3 indicarem maior gravidade da DHPN, sugere-se que outras variáveis sejam analisadas conjuntamente, uma vez que os relatos existentes na literatura, até o momento, não dão suporte para seu uso como instrumento exclusivo de avaliação de gravidade e prognóstico da doença.

The present study it had for objective to search the AIE in equids traction of the city of Cuiaba, of which if it extracted an inquiry epidemiologist and a sampling of blood serum of 113 animals (110 equines and 3 mules) that they transited for the public ways. The sampling of the animals was random how much to the age (of 8 months the 20 years) and sex of the animals where 67 (60.9%) were of females and 46 (41.8%), of males, with a average of 22 working hours per week. The samples of blood had been analyzed by means of the technique of AGID test. The results of the blood tests had indicated that of the 110 examined samples of blood serum of the equines, thirteen (11.8%) were positive, being seven of female (10.4% of the total of females) and 6 males (13.0% of the total of males), all no symptoms animals and the age of the positive animals was concentrated in the band of 6 10 years, representing 84.6% (11 animals). The results of the blood tests had also indicated that of three mules analyzed, 1 (33.3%) was positive.

The present study sought to determine the prevalence of anemia in 2,992 children, aged between 6 and 23 months, who voluntarily attended 160 Basis Health Care Units, located in 63 cities of the 5 Regional Health Coordinating areas of the State of S. Paulo, Brazil. Blood samples were collected by venous puncture and hemoglobin was measured by the cianometahemoglobin method. The WHO criteria for the diagnosis of anemia (Hb < 11.0 g/dl) were used: 59.1% of the children were shown to be anemic, with prevalence varying from 47.8% to 68.7% in the 5 RHCs. RHC 1, which comprises the Greater S. Paulo Region, presented a prevalence of anemia significantly lower than the other 4 RHCs, which cover the rest of the State. Hemoglobin levels 9.5 g/dl were found in 25.1% of the children. Anemia was more frequent in male children in male children, in those born, with a weight of less than 3,000 gr, in those who were breastfed for less than 2 months and in those that who presented some degree of energy deficient proteic malnutrition, according to Gomez's criteria. This is the first of a series of 4 articles whose purpose is the determining the prevalence of anemia in the State of S. Paulo and of testing the intervention alternatives with a view to curtailing the incidence of this pathology which today is the most prevalent nutritional disturbance in the world.
