“…3,4 In the Brazilian Amazon basin, anemia has been found in 28% of the inhabitants of a malaria-endemic area, ranging from 70% in infants and 38.4% in young children to 44.4% among malaria patients. 5 Malaria remains as another important cause of anemia in tropical countries. 6,7 One-fourth of all malaria cases detected in the Americas are from Bolivia, Colombia, Ecuador, Peru and Venezuela.…”

Abstract. The prevalence and age distribution of anemia and malaria among Yanomami Amerindians undergoing sociocultural assimilation are described. Anemia and malaria proportions were determined in 103 individuals randomly selected from 515 villagers in Mavaca in the southern Venezuelan Amazon. The age and sex distribution reflected that of the entire village cluster. Anemia (hematocrit less than World Health Organization/Centers for Disease Control and Prevention reference values) was found in 91% of the study population. As a group, adults (Ն 15 years old) had the highest proportion of anemia (P ϭ 0.037). Adult females had lower mean hematocrit values than adult males (P ϭ 0.013). The anemia was predominantly hypochromic and microcytic (62%), a finding that could suggest a diagnosis of iron deficiency in the absence of known hereditary hemoglobinopathies in these Amerindians. Malaria was diagnosed in 14% overall. Children (Ͻ 10 years old) displayed the highest proportion of Plasmodium falciparum (17%) and P. vivax (14%) parasitemia, splenomegaly (94%), and fever (34%) (P ϭ 0.059, 0.039, 0.005, and 0.008, respectively). The high proportions of anemia and splenomegaly observed in the survey may be used as indicators of inadequately controlled malaria in this community. Further studies to assess the epidemiology of risk factors for the high prevalence of anemia, and predominance of P. falciparum infections in the area are urgently needed.

“…Dados similares foram referidos por Cardoso et al 35 , estudando a prevalência da anemia em Rondônia. Por outro lado, a anemia foi significativamente maior nos pacientes com malária por P. vivax com exame de fezes positivo para ancilostomídeos, haja vista a bem documentada associação da anemia com esse tipo de helminto 36 .…”

Objective: Evaluation of epidemiological, clinical and laboratory features of Plasmodium vivax malaria in children and adolescents.Methods: This study was carried out in the Malaria Program of the Evandro Chagas Institute (Belém, Pará), from January 1995 to November 1996. 100 children and adolescents with the diagnosis of P. vivax malaria (thick blood film) were randomly enrolled. A protocol was created to assess epidemiological, clinical and laboratory parameters of this pathology.Results: Malaria occurred in both sexes, and had a prevailing incidence among adolescents (37%). Most of the children and adolescents (92%) had been infected in the State of Pará. Autochthonous cases in the metropolitan area of Belém accounted for 34 % of the sample. Primary infection was seen in 80% of the patients. Fever was the major onset clinical symptom (88%). A history of typical febrile paroxysm was recorded in only 25% of the casuistic. In the first day of treatment (D0) fever (97%), chills (91%), pallor (85%), splenomegaly (46%) and hepatomegaly (29%) were some of the clinical features observed. Pallor (clinical signal) was found to be significantly (p=0.0004) associated with anemia (hemoglobin rate). There was a high significant negative correlation (p=0.0001) between delay of diagnosis (mean 12,5 days) and hemoglobin values. Regarding parasitological examination, just children and adolescents with positive results to hookworms were significantly (p=0.0133, p=0.0075) more anemic than those who had a positive parasitological examination to other helminths and/or protozoa species.Conclusions: Malaria affected children and adolescents from both sexes. An emphasis on epidemiological and clinical data is an important tool to the precocious diagnosis of the disease. Delay on diagnosis made anemia worse. ResumoObjetivo: Avaliação dos aspectos epidemiológicos, clínicos e laboratoriais da malária por Plasmodium vivax em crianças e adolescentes.Métodos: No ambulatório do Programa de Malária do Instituto Evandro Chagas (Belém-Pará), no período de janeiro de 1995 a novembro de 1996, foram estudadas de modo aleatório 100 crianças e adolescentes com diagnóstico positivo por gota espessa para malária por P. vivax. Elaborou-se um protocolo para avaliação dos aspectos epidemiológicos, clínicos e laboratoriais dessa patologia.Resultados: Acometimento de ambos os sexos, com predomí-nio entre os adolescentes (37%). As crianças e adolescentes em sua maioria (92%) adquiriram a infecção no Pará. Os casos autóctones, área metropolitana de Belém, representaram 34% da amostra. Primoinfecção ocorreu em 80% dos pacientes. Febre foi a manifestação clínica inicial mais freqüente (88%). Relato de paroxismo febril típico (febre terçã) foi obtido em somente 25% da casuística. No 1º dia de tratamento (D0) febre (97%), calafrio (91%), palidez (85%), esplenomegalia (46%) e hepatomegalia (29%) foram alguns dos sinais e sintomas observados. Houve significância estatística (p=0,0004) na correlação entre palidez (avaliação clínica) e anemia (taxa de hemo...
