MARQUES, Marli; CAZOLA, Luiza Helena  and  CHEADE, Maria de Fátima Meinberg. Avaliação do SINAN na detecção de co-infecção TB-HIV em Campo Grande, MS. Bol. Pneumol. Sanit. [online]. 2006, vol.14, n.3, pp.135-140. ISSN 0103-460X.

Surveillance and control of concurrent infection by the human immunodeficiency virus (HIV) and Mycobacterium tuberculosis require an information system of high quality, capable of providing knowledge on the routine of anti-HIV testing and its results. This study analyzed data on the collection of samples for anti-HIV serology, results, test coverage, and maximum and minimum prevalence of co-infection in Campo Grande, MS, Brazil, in the period 2000-2005. In addition, inconsistencies were searched for in the records of 2003 in the Brazilian Information System of Notifi able Hazards (SINAN) database and in the Registry of Cases of Tuberculosis. An annual average of 259 cases were notified, with an increase in the percentage of cases for which anti-HIV serology was investigated (from 44.3% to 85.5%), a decrease in the records categorized as 'Being Processed' (from 27.7% to 7.3%) and an increase in the number of cases tested (from 32% to 78.9%). Minimum prevalence of TBHIV co-infection ranged from 8.5% (18/212) in 2000 to 16.6% (48/289) in 2005, whereas maximum prevalence ranged from 18.2% (35/192) in 2004 to 37.9% (36/95) in 2002. Cross-checking between the Registry of Cases and the SINAN database revealed 15.4% of under-reporting in the latter. Cross-checking of 226 HIV results showed disagreement in 81 records (35.8%). Improvements in counseling and testing routines were identified, as well as an increase in the prevalence of co-infection, although under-reporting and inconsistencies in the records should be the object of measures designed to minimize or preclude the occurrence of such events.

Keywords : tuberculosis, TB-HIV co-infection, prevalence, epidemiological surveillance, SINAN.
