RESUMO

A tuberculose continua a ser, em Portugal, um importante problema de Saúde Pública, com uma incidência de 55.8/100.000 habitantes, em 1991.

Sendo os doentes baciliferos a principal fonte de contágio, os nossos esforços são sempre centralizados no diagnóstico precoce e tratamento efectivo dos mesmos.

Os seus conviventes são um grupo de alto risco pelo que a nossa actividade preventiva deve incidir, preferencialmente, sobre eles.

Os autores propuseram-se avaliar a rentabilidade e eficáicia das medidas tomadas no rastreio dos conviventes dos casos de tuberculose pulmonar admitidos entre Julho de 1992 e Junho de 1993. Neste período, foram classificados 275 doentes como tuberculose, 152 (55.3%) dos quais com tuberculose pulmonar.

A taxa de confirmação foi de 84.2%. Identificámos 441 contactos (3.3/caso índice), correspondendo a 131 casos índice. Compareceram ao rastreio 345 (78.2%), sendo o tempo médio decorrido entre a consulta do caso índice e o rastreio dos conviventes de 18.3 dias.

Diagnosticámos tuberculose pulmonar em 9 conviventes (2.6%) e tuberculose infecção em 33 (9.6%).

Discutimos mais pormenorizadamente os resultados encontrados e concluimos, entre outras, que houve uma boa adesão dos conviventes ao rastreio, da sua importância na detecção da tuberculose doença e infecção e da necessidade de se prolongar a vigilância dos contactos.

SUMMARY

In Portugal, tuberculose (TB) remains a serious health problem, with an incidence rate of 55.8 in 1991.

As the risk of transmission is mainly from the sputum positive TB cases, our efforts have to be directed towards an early diagnosis and a correct treatment of those cases.

Contacts, as a group, are at a high risk. They are the most important on wich to focus preventive intervention.

Working the authors in a Tuberculosis Unit in the Lisbon District, they proposed to evaluate their effectiveness on contacts investigation of pulmonary tuberculosis cases admitted between July 1992 and June 1993. In this period, 275 patients with TB were admited, 152 (55.3%) with pulmonary tuberculosis. The confirmation rate was of 84.2% of 131 index cases, we identified 441 contacts (3.3 contacts/index case).

Three hundred and forty five attended the investigation (78.2%). The mean time elapsed between consultation of the index case and the investigation of the contacts was of 18.3days.

Tuberculosis disease was diagnosed in 9 contacts (2.6%,) and tuberculosis infection in 33 (9.6%.).

The results of both situations are discussed in detail. As conclusions, among others, we can say there was a good participation of the contacts, the importance of their investigation in the detection of tuberculosis disease and infection and the need to prolong the surveilance of the contacts.
