A qualitative study exploring the parceived impact of race on leprosy-affected persons' experiences of diagnosis and treatment of leprosy in Southeast Brazil

Leprosy is a chronic, yet curable, infectious disease that causes severe morbidity in Brazil with an annual incidence of 33,000 new cases. Recent studies in Brazil showed a correlation between leprosy and the percentage of non-whites affected. Racial discrimination has been documented as a barrier to accessing healthcare. This study seeks to explore whether patients perceive race to have impacted on their leprosy care. A qualitative study was undertaken. 20 semi-structured interviews were conducted with patients' at Instituto Lauro de Souza Lima (ILSL), Brazil. Thematic analysis was used to analyse the data. 4 main themes were generated: racism is part of Brazilian culture, difficulties associated with the diagnosis of Leprosy, barriers to accessing treatment, and a lack of health education. Participants felt that racism infiltrates all aspects of Brazilian society, with isolated incidents in healthcare settings. Racism is known to be associated with socioeconomic inequalities. Leprosy control continues to be hindered by various social determinants of health. This, in turn, affects patients' access to leprosy treatment and care. This study may inform the continuing development of equitable leprosy control strategies in Brazil.

Factors contributing to the delay in diagnosis and continued transmission of leprosy in Brazil - an explorative, quantitative, questionnaire based study

BACKGROUND: Leprosy is a leading cause of preventable disability worldwide. Delay in diagnosis of patients augments the transmission of infection, and allows progression of disease and more severe disability. Delays in diagnosis greater than ten years have been reported in Brazil. To reduce this delay, it is important to identify factors that hinder patients from presenting to doctors, and those that delay doctors from diagnosing patients once they have presented. This study aimed to explore factors associated with the delayed diagnosis of leprosy in Brazil. METHODOLOGY/ PRINCIPAL FINDINGS: This is an exploratory study using a self-constructed questionnaire delivered to patients attending three leprosy referral clinics across three states in Brazil. Data were analysed to determine associations between variables and the time taken for participants to present to the health-service, and between variables and the time taken for doctors to diagnose participants once they had presented. Participants who suspected they had leprosy but feared community isolation were 10 times more likely to wait longer before consulting a doctor for their symptoms (OR 10.37, 95% CI 2.18-49.45, p = 0.003). Participants who thought their symptoms were not serious had a threefold greater chance of waiting longer before consulting than those who did (OR 3.114, 95% CI 1.235-7.856, p = 0.016). Forty-two point six per cent of participants reported initially receiving a diagnosis besides leprosy. These had a three times greater chance of receiving a later diagnosis of leprosy compared to those not misdiagnosed or not given a diagnosis (OR 2.867, 95% CI 1.288-6.384, p = 0.010). CONCLUSIONS/ SIGNIFICANCE: This study implies a need for patient education regarding leprosy symptoms and the reduction of stigma to encourage patients to present. The high rate of misdiagnosis reported suggests a need to increase clinician suspicion of leprosy. Further education regarding disease symptoms in medical school curriculums may be advisable.
