ABSTRACT Pyruvate kinase is an essential enzyme in the anaerobic glycolytic pathway of the erythrocyte. The clinical presentation of this enzyme deficiency is due to the haemolytic process that results from the inability of erythrocytes to generate sufficient ATP. Although pyruvate kinase and glucose-6-phosphate dehydrogenase deficiencies comprise more than 90% of all reported red cell enzyme disorders worldwide, the epidemiology of the disease in South Africa is unknown and there is no assay for pyruvate kinase activity currently being used in South Africa. This report describes the implementation of screening and quantitative assays for pyruvate kinase activity in the Red Cell Membrane Unit at the University of the Witwatersrand Medical School / NHLS. The accuracy, precision and reproducibility of the assay were verified. Furthermore, a patient with pyruvate kinase deficiency was confirmed and found to have 15% of normal enzyme activity at 37oC. The genetic abnormality was identified as a homozygous G1529A point mutation in exon 11 of the pyruvate kinase gene and to the candidate’s knowledge is the first mutation described in a South African kindred. The patient’s mother was heterozygous for the G1529A mutation and demonstrated an enzyme activity of 58% of normal at 37oC.

Objetivo: A prevalência e incidência da tuberculose na população prisional é muito maior que na população geral. Conhecer a prevalência de infectados, doentes e características físicas, sociais e criminais dos presos, foram objetos deste estudo. Método: Realizou-se uma busca ativa de casos de tuberculose nos 1.052 detentos de 9 Distritos Policiais da Zona Oeste da Cidade de São Paulo, entre 2000-2001. Após a aplicação de um inquérito e da prova tuberculínica, foram realizados os exames de baciloscopia, cultura, identificação e teste de sensibilidade às drogas antituberculose. Resultados: Do total de 1.052 detentos 99,7 por cento eram homens; 71,3 por cento tinham entre 18 e 29 anos; 82,4 por cento eram solteiros ou amasiados; 51,4 por cento eram pretos ou pardos; 64,5 por cento não completaram o 1º grau; 40 por cento praticaram o roubo como principal delito; 3,7 por cento tiveram tuberculose no passado e 32,8 por cento eram sintomáticos respiratórios. Dos 932 que fizeram a prova tuberculínica, 64,5 por cento estavam infectados. Dos 1.017 escarros analisados, 8 (0,8 por cento) foram positivos na baciloscopia e 54 (5,3 por cento) na cultura. Das 54 cepas isoladas, 38,9 por cento eram M. tuberculosis e 61,1 por cento eram micobactérias não tuberculosas. Das 21 cepas de M. tuberculosis, 85,7 por cento eram sensíveis, 9,5 por cento eram resistentes à isoniazida e rifampicina e 4,8 por cento à isoniazida, rifampicina e pirazinamida. Conclusões: Pela baciloscopia, o coeficiente de prevalência de tuberculose (por 100.000 detentos) foi de 787, e pela cultura de 5.310, cerca de 30 e 203 vezes mais que o da população da cidade de São Paulo, respectivamente. O fato de haver 3 detentos com cepas multirresistentes às drogas antituberculose é uma ameaça à saúde pública / Purpose: The prevalence and incidence of tuberculosis in inmates population is much larger than in the general population. The purpose of this study was acquiring good knowledge of the prevalence of infected person and tuberculosis patients, as well as the physical, social and criminal characteristics of inmates. Method: An active search of tuberculosis cases was conducted among the 1,052 inmates of 9 County Jails of the West Section of the São Paulo City between 2000-2001. After application of an inquiry and the tuberculin skin test, laboratory investigations were also conducted such as sputum bacilloscopy, culture, identification and the test of sensitivity to anti-TB drugs. Results: Out of the total number of 1,052 inmates, 99.7 per cent were males; 71.3 per cent were in the group of ages 18 and 29 years old; 82.4 per cent were single or had sexual mates; 51.4 per cent were negroes or mulattos; 64.5 per cent had low education level; 40 per cent had been engaged in thefts/robberies; 3.7 per cent had tuberculosis episodes in the past and 32.8 per cent displayed respiratory symptoms. Out of the 932 which underwent the tuberculin skin test, 64.5 per cent were infected. Out of the 1,017 sputum samples analyzed, 8 (0.8 per cent) had positive bacilloscopy and 54 (5.3 per cent) positive culture. Of the 54 strains isolated, 38.9 per cent were M. tuberculosis and 61.1 per cent were non-tuberculosis mycobacteria. Of the 21 M. tuberculosis strains 85.7 per cent were sensitive, 9.5 per cent were resistant to isoniazide and rifampicin and 4.8 per cent to isoniazide, rifampicin and pyrazinamide. Conclusions: Based on the bacilloscopy, the tuberculosis prevalence rate (per 100,000 inmates) was 787 and based on the culture was 5,310 inmates, around 30 and 203 times higher than that of the São Paulo city population, respectively. The fact that 3 inmates had strains multi-resistant to anti-TB drugs can be deemed a threat to the public health
