Abstract Background The evaluation of household contacts of leprosy cases allows the early diagnosis of new cases. Objective To associate the results of the ML Flow test with the clinical characteristics of leprosy cases and to verify their positivity in household contacts, in addition to describing the epidemiological profile of both. Methods Prospective study with patients diagnosed over the course of one year (n = 26), without prior treatment, and their household contacts (n = 44) in six municipalities in northwestern São Paulo, Brazil. Results There was a predominance of men among the leprosy cases, of 61.5% (16/26); 77% (20/26) were over 35 years old; 86.4% (22/26) were multibacillary; 61.5% (16/26) had a positive bacilloscopy; and 65.4% (17/26) had no physical disability. The ML Flow test was positive in 53.8% (14/26) of the leprosy cases and was associated with those who had a positive bacilloscopy and were diagnosed as multibacillary (p-value <0.05). Among the household contacts, 52.3% (23/44) were women and aged over 35 years; 81.8% (36/44) had been vaccinated with BCG ‒ Bacillus Calmette-Guérin. The ML Flow test was positive in 27.3% (12/44) of household contacts, all of whom lived with multibacillary cases; seven lived with positive bacilloscopy cases and six with consanguineous cases. Study limitations Difficulty in convincing the contacts to undergo the evaluation and collection of the clinical sample. Conclusion The ML Flow test, when positive in household contacts, can help the identification of cases that require more attention by the health team, as it indicates a predisposition to disease development, especially when they are household contacts of multibacillary cases, with positive bacilloscopy and consanguineous. The ML Flow test also helps in the correct clinical classification of the leprosy cases.

Resumo Objetivo: Apresentar o diagnóstico situacional da rede laboratorial para hanseníase na região de São José do Rio Preto, SP, Brasil. Métodos: Pesquisa de avaliação com desenho descritivo. Os dados foram coletados por meio de formulário online preenchido pelos responsáveis pelo programa de hanseníase, em 2018. Resultados: Todos os 102 municípios que compõem a região enviaram os dados solicitados, 84 (82,4%) solicitavam a baciloscopia; e destes, 68 receberam capacitação. Do total, 11,7% enviavam baciloscopia para outros laboratórios sem respeitar a rede de referência. Apenas 59 (57,8%) solicitavam a biópsia, e destes, 47 tinham médico responsável pela coleta e 31 não respeitavam a rede de referência para encaminhamento das biópsias. Foram descritos, como aspectos que dificultavam o diagnóstico dos casos de hanseníase na região, a falta de sala adequada, poucos profissionais capacitados, ausência de material para transporte e de requisição de exames impressa. Conclusão: A rede laboratorial se encontra fragilizada, necessitando reestruturação.

Abstract Objective: To present the situational diagnosis of the leprosy laboratory reference network in the region of São José do Rio Preto, SP, Brazil. Methods: This was an evaluation study with a descriptive design. The data were collected by means of an online form filled in by those in charge of the leprosy program in 2018. Results: All 102 municipalities that make up the region provided the requested data, 82.4% (84/102) requested slit-skin smear microscopy and of these 68 received training. Of the total, 11.7% sent slit-skin smears to other laboratories outside the reference network. Only 57.8% (59/102) requested a biopsy, of these 47 had a doctor responsible for taking the biopsy sample and 31 did not send biopsy samples for analysis in the reference network. Lack of an adequate room, few trained professionals, absence of material for transportation and absence of printed test requisitions were described as aspects that hinder leprosy case diagnosis in the region. Conclusion: The laboratory network is fragile and needs to be restructured.

Resumen Objetivo: Presentar el diagnóstico de la situación de la red de laboratorios para lepra en la región de São José do Rio Preto, SP, Brasil. Métodos: Estudio de evaluación con diseño descriptivo. Los datos fueron recolectados a través de un formulario en línea por cada persona responsable del programa de lepra en 2018. Resultados: Los 102 municipios que conforman la región enviaron los datos solicitados, el 82,4% (84/102) solicitaba la baciloscopia y de estos 68 recibieron capacitación. Del total, el 11.7% enviaba la baciloscopia a otros laboratorios sin respetar la red de referencia. Solo el 57,8% (59/102) solicitó una biopsia, y de estos, 47 tenía un médico responsable de la recolección y 31 no respetaron la red de referencia para enviar las biopsias. Los aspectos que dificultan el diagnóstico de casos de lepra en la región SJRP se describieron como la falta de una sala adecuada, profesionales capacitados, ausencia de material para el transporte y de solicitudes de exámenes impresos. Conclusión: La red de laboratorios está fragilizada y debe ser respetada en su composición inicial o reexaminada y reorganizada.
