Abstract
BACKGROUND
Leprosy is the main infectious cause of disability. It is said to be eradicated in São Paulo since 2005, but diagnosis is still late.
OBJECTIVES
To investigate the social, clinical and laboratorial profile of leprosy patients diagnosed between 01/2007 and 12/2011, in a reference center in São Paulo.
METHODS
Retrospective descriptive study. Data of all new leprosy cases diagnosed between 01/2007 and 12/2011 were raised in São Paulo.
RESULTS
103 men and 71 women were diagnosed, most of them were multibacillary. Mean age at diagnosis was 49 yrs; 2,2% were children; 70% had incomplete primary education; 50% were referred without diagnostic suspicion of leprosy. Mean time since first symptoms/signs and diagnosis was 2 years; 64% of patients had some degree of disability, and 26% had grade 2. 23 cases were diagnosed only after being summoned, and 80% of these had no disability. Agreement between the Ridley and Jopling and the WHO classification was 75% (kappa index = 0.44). Serology for IgM anti-PGL1 (87 patients) showed a mean value of 0.25, and an association between MB classification and test positivity (p <0.001).
CONCLUSIONS
Leprosy diagnosis in São Paulo is late. The disease mainly affected the socially disadvantaged and economically active population. Failure to detect the disease (41% in the last 10 years) could be due to the lack of suspicion and to decentralization. For the classification of patients with advanced leprosy, both the WHO and R&J classifications proved to be helpful tools.
