A campanha brasileira foi realizada em quatro iterações entre 2013 e 2017. O público-alvo foram crianças de 5 a 14 anos matriculadas em escolas públicas municipais de todo o país. Em resumo, foi detectado um total de 1 074 e 73 522 novos casos de hanseníase e tracoma, respectivamente. Foram administradas cerca de 18 milhões de doses de quimioterapia preventiva para helmintíase transmitida pelo solo. Mais de 700 casos de esquistossomose foram diagnosticados e tratados. Conclusões. As estratégias integradas implementadas no Brasil ao longo da campanha geraram resultados alinhados com as recomendações da OMS para o controle de doenças tropicais negligenciadas, especialmente aquelas relativas à administração em massa de medicamentos, à detecção ativa de casos e à intensificação da gestão de casos. Portanto, a continuidade da campanha com ferramentas de avaliação adequadas deve ser incentivada como uma política de saúde pública constante na agenda do governo brasileiro.

RESUMEN Objetivo. Describir los resultados de una campaña nacional dirigida al control integrado de las enfermedades tropicales desatendidas en Brasil, a la luz de la documentación oficial de la Organización Mundial de la Salud (OMS) relacionada con la integración de estrategias para la prevención, el control y la eliminación o erradicación de las enfermedades tropicales desatendidas. Métodos. Revisión documental que comprendió documentos oficiales de la OMS publicados entre el 2007 y el 2020, así como los resultados de las campañas, extraídos del informe técnico oficial elaborado por el Ministerio de Salud de Brasil. Resultados. Con el tiempo, la OMS ha ido incorporando gradualmente en sus documentos el concepto de control integrado de las enfermedades tropicales desatendidas. Tanto los tratamientos quimioprofilácticos mediante la administración masiva de medicamentos como la intensificación del tratamiento de los casos y el control integrado de vectores han sido recomendados ampliamente como estrategias para el control integrado. En Brasil, la campaña se llevó a cabo en cuatro ediciones, realizadas entre el 2013 y el 2017. Las actividades estuvieron dirigidas a la población escolar de entre 5 y 14 años de las escuelas públicas municipales de todo el país. En resumen, se detectaron 1 074 y 73 522 casos nuevos de lepra y tracoma, respectivamente; se administraron casi 18 millones de dosis de tratamiento quimioprofiláctico contra las geohelmintiasis; y se diagnosticaron y trataron más de 700 casos de esquistosomiasis. Conclusiones. Las estrategias integradas aplicadas en Brasil en el transcurso de la campaña permitieron obtener resultados acordes con las recomendaciones de la OMS para el control de las enfermedades tropicales desatendidas, especialmente en lo relativo a la administración masiva de medicamentos, la búsqueda activa de casos y la intensificación de su tratamiento.

ABSTRACT Objective. To describe the results of a national campaign aimed at the integrated control of neglected tropical diseases in Brazil in light of the World Health Organization (WHO) official documentation related to the integration of strategies for the prevention, control, and elimination or eradication of neglected tropical diseases. Methods. A document review that included official WHO documents published between 2007 and 2020 and campaign results extracted from the official technical report produced by the Brazilian Ministry of Health. Results. The integrated control of neglected tropical diseases was gradually incorporated in the WHO documentation over time. Preventive chemotherapy through mass drug administration, intensified case management, and integrated vector management were extensively recommended as strategies for integrated control. The Brazilian campaign was carried out in four iterations between 2013 and 2017. Children aged 5 to 14 years enrolled in municipal public schools nationwide were targeted. In summary, a total of 1 074 and 73 522 new cases of leprosy and trachoma, respectively, were detected. Nearly 18 million doses of preventive chemotherapy for soil-transmitted helminthiasis were administered. More than 700 cases of schistosomiasis were diagnosed and treated. Conclusions. The integrated strategies implemented in Brazil throughout the campaign generated results aligned with the WHO recommendations for the control of neglected tropical diseases, especially those regarding mass drug administration, active case detection, and intensified case management. Therefore, the continuity of the campaign with adequate evaluation tools must be encouraged as a constant public health policy in the Brazilian government agenda.

ABSTRACT Background: This cross-sectional study compared the general impact of cutaneous leishmaniasis (CL) and patient satisfaction with treatment and health services as perceived by those undergoing different therapeutic regimens in an endemic region in South-Eastern Brazil. We also investigated the factors associated with both outcomes (general impact and satisfaction). Methods: We included 84 patients with CL treated between 2018 and 2019 with intravenous meglumine antimoniate, liposomal amphotericin B, or intralesional meglumine antimoniate therapy. Data were collected through interviews that assessed sociodemographic characteristics, comorbidity status, access and use of health services for CL diagnosis and treatment, and the items of the Cutaneous Leishmaniasis Impact Questionnaire (CLIQ). The CLIQ is a psychometric questionnaire previously validated to assess the general impact of CL on patient satisfaction with treatment and health services. Multivariate logistic regression analysis was used to identify the factors associated with high CL impact and low patient satisfaction. Results: The general impact of CL and patient satisfaction with treatment and health services were not significantly associated with the therapeutic regimen. High CL impact was associated with low family income (odds ratio [OR]:3.3; 95% confidence interval [CI]:1.0-10.3), occurrence of complications/adverse effects during treatment (OR:7.7; 95%CI:2.4-25.6), and additional costs during diagnosis and/or treatment (OR:12.1; 95% CI:2.8-52.4). Low satisfaction was associated with high disease impact (OR: 9.5; 95% CI:2.7-33.9), occurrence of complications/adverse effects (OR:4.2; 95% CI:1.3-13.0), and high family income (OR:7.1; 95%CI:1.7-28.2). Conclusions: Our data support public health policies aimed at reducing the impact of CL and its treatment as well as the use of therapy with fewer adverse effects.

ABSTRACT This cross-sectional population-based study compared clinical features of leprosy and American tegumentary leishmaniasis (ATL) in patients diagnosed with both diseases (n=414) and in those diagnosed with only leprosy (n=27,790) or only ATL (n=24,357) in Mato Grosso State, which is a hyperendemic area for both diseases in Midwest Brazil. All new cases of leprosy and ATL reported in the area from 2008 to 2017 were included. Patients diagnosed with both diseases were identified by a probabilistic linkage procedure applied to leprosy and ATL databases of the national reporting system. The distribution of the frequency of clinical features between groups was compared by the chi-square test, followed by a multivariate logistic regression. Patients diagnosed with both leprosy and ATL presented higher odds of having nerve damage (OR: 1.34; 95% CI: 1.09–1.66) and leprosy reactions (OR: 1.35; 95% CI: 1.04–1.76) compared to patients diagnosed only with leprosy. Mucocutaneous leishmaniasis (OR: 2.29; 95% CI: 1.74–3.00) was more frequent among patients with both diagnoses when compared to patients who only had ATL. In conclusion, patients diagnosed with both leprosy and ATL present more severe clinical features of such diseases. Our data can be useful for designing health policies aimed at timely and integrated management of leprosy and ATL in co-endemic areas.

ABSTRACT Health education and training of primary health care (PHC) professionals are highly recommended to reduce the occurrence and lethality of visceral leishmaniasis (VL). This study assessed the impact of an educational intervention on the basic knowledge about visceral leishmaniasis (VL) among PHC professionals from the Brazilian municipality of Rondonopolis, an important endemic area for VL. Responses provided by physicians, nurses, nursing technicians and community health agents from 12 PHC facilities were recorded through the application of self-completed and semi-structured questionnaires before (n=92) and after (n=64) an in-person health training course covering various aspects of VL. Closed- and open-ended responses were compared by the chi-square test and analyses of word clouds, respectively. The proportion of professionals aware of the correct etiological agent (p<0.001) and transmission route (p<0.001) of VL increased post-intervention. In addition, they increased their ability to recognize fever (p<0.001), weakness (p<0.001), weight loss (p<0.001), pallor (p<0.001) and abdominal distention (p=0.013) as clinical manifestations of human VL, and weakness (p<0.001), alopecia (p<0.001) and weight loss (p=0.019) as signs of canine VL. Analyses of word clouds suggested that the participants became more aware of the role of dogs in VL transmission and the role of environmental management in the prevention of VL. In conclusion, the intervention positively impacted the baseline knowledge concerning VL among the professionals. This can support the planning of educational activities for the PHC team regarding early case detection, prevention and control of VL in endemic areas.

BACKGROUND Timely diagnosis is recommended by the Brazilian Visceral Leishmaniasis (VL) Surveillance and Control Program to reduce case fatality. Attempts at assessing this topic in Brazil are scarce. OBJECTIVE This study aimed to describe where, when, and how the diagnosis of VL has been performed in a Brazilian endemic setting. METHODS Data of all autochthonous cases confirmed between 2011 and 2016 (N = 81) were recorded. The care-seeking itinerary until the confirmation of VL diagnosis was assessed among 57 patients. FINDINGS The majority of VL cases (79.1%) were reported by referral hospitals. The patients mainly sought primary health care centres at the onset of symptoms. However, they had to visit seven health services on average to achieve a confirmed diagnosis. The time from the onset of symptoms to the diagnosis of VL (TD) ranged from 1-212 (median, 25) days. The TD was longer among adult patients. There was a direct correlation between the patient’s age and TD (r = 0.22; p = 0.047) and a higher occurrence of deaths due to the disease among older patients (p = 0.002). Almost all the patients (98.9%) underwent laboratory investigation, and the VL diagnosis was mainly confirmed based on clinical-laboratory criteria (92.6%). Positive results for the indirect fluorescence antibody test (22.7%) and parasitological examination plus rk39-based immunochromatographic tests (21.3%) were commonly employed. MAIN CONCLUSIONS VL diagnosis was predominantly conducted in hospitals with a long TD and wide application of serology. These findings may support measures focused on early diagnosis, including a greater involvement of the primary health care system.

ABSTRACT The Brazilian municipality of Rondonópolis, Mato Grosso State, represents an important visceral leishmaniasis (VL) endemic area. This study described epidemiological and clinical aspects of the occurrence, VL/HIV coinfection and lethality related to VL in Rondonópolis. Data from autochthonous cases reported between 2011 and 2016 were obtained from official information systems. During this period, 81 autochthonous cases were reported, with decreasing incidence through 2016. Contrastingly, the lethality rate was 8.6% overall, but varied widely, reaching a peak (20%) in 2016. Almost 10% of patients had VL/HIVcoinfection. The occurrence of VL prevailed among men (56.8%), brown-skinned (49.4%), urban residents (92.6%), aged 0-4 years (33.3%). Housewives or retired (29.6%) were the most affected occupational groups. Lower age was the main difference among the total VL cases and those who were coinfected or died. Clinically, fever, weakness and splenomegaly were more frequent among all VL cases and VL/HIV coinfected individuals. Bacterial infections (p=0.001) and bleeding (p<0.001) were associated with death due to VL. Pentavalent antimonial and liposomal amphotericin B were the first choices for treatment among all VL cases (71.6%) and those who died (71.4%), respectively. VL/HIV patients were equally treated with both drugs. These findings may support control measures and demonstrate the need for further investigations.

RESUMO Objetivo: O presente estudo teve como objetivo avaliar a presença de helmintos e protozoários intestinais em hortaliças comercializados em Diamantina, um município localizado no Vale do Jequitinhonha, uma das regiões mais pobres do mundo. Métodos: Cento e oito exemplares, incluindo alface, cebolinha e rúcula, foram mensalmente coletados em uma feira livre, uma quitanda e um supermercado do município. As amostras foram processadas por um método de concentração e avaliadas por microscopia óptica para pesquisa de estruturas parasitárias. Resultados: O percentual global de contaminação foi de 50,9% (55/108), com predominância de larvas de nematódeos (36,5%), cistos de Entamoeba coli e ovos de ancilostomídeos/Strongyloides spp. (12,9%). A alface demonstrou a maior taxa de contaminação (61,1%) e as amostras da feira livre foram as mais contaminadas (77,8%). Informações coletadas em cada ponto de venda apontaram o cultivo em campo como a etapa crítica para a contaminação. Conclusão: Hortaliças comercializadas em Diamantina apresentam uma ampla variedade de parasitas intestinais, o que representa um risco potencial à saúde dos consumidores da área.

ABSTRACT Objective: The present study aimed to evaluate the presence of helminthes and intestinal protozoa in vegetables commercialized in Diamantina, a municipality located at Jequitinhonha Valley, one of the poorest regions of the world. Methods: A total of 108 specimens, including lettuce, green onion and rocket, were monthly collected from the most popular open street market, green grocery and supermarket of the municipality. The samples were processed by a concentration method and evaluated by light microscopy for parasitological identification. Results: The percentage of contamination was 50.9% (55/108), with predominance of nematode larvae (36.5%), cysts of Entamoeba coli (26.0%) and eggs of hookworms/Strongyloides spp. (12.9%). Lettuce showed greater contamination rate (61.1%) and samples from the open street market were more contaminated (77.8%). Information collected at each point of sale pointed the field cultivation as the critical step for such contaminations. Conclusion: Vegetables marketed in Diamantina presents a wide variety of intestinal parasites, which may represent a potential risk to the health of consumers of fresh vegetables.
