“…These data are linked to habits and to the body sites that are most exposed to phlebotomine bites, as observed in studies by Paniz-Mondolfi et al 5 and Brito et al 41 , which showed that the most exposed areas and those most susceptible to the vector in a clinically localized form are the face, upper limbs, and lower limbs. Castro et al 34 showed that cutaneous lesions were located primarily in the lower limbs (47.7%), followed by the upper limbs (26.7%), and the face (16.0%), corroborating the results of our study. Grangeiro-Júnior et al 25 reported that the lower limbs were the most affected body site (n = 164, 45.18%), followed by the upper limbs (n = 82, 22.59%), head (n = 34, 9.37%), and abdomen (n = 24, 6.61%).…”

“…Most of the patients included in the current study had only one lesion. Consistent with this finding, Figueira et al 34 demonstrated that in the municipality of Rio Preto da Eva in the state of Amazonas, at least 56.7% of the individuals with ACL presented with only one lesion and 43.4% presented with more than one. In a study conducted by Castro et al 35 in the north of Paraná, 67% of the individuals were found to have only one lesion and 31% had two or more.…”

Introduction: Brazil has a high number of cases of American cutaneous leishmaniasis (ACL) in the north and northeast regions. Therefore, continuous surveillance of environmental and socioeconomic factors in endemic areas is needed to develop strategic control measures. This study aimed to describe the clinical and epidemiological profiles of patients with ACL. Methods: All patients were from the states of Amazonas and Pernambuco, and examinations were carried out between 2015 and 2018. All patients had a clinical and epidemiological history compatible with ACL after positive diagnostic tests. Information obtained from medical records included gender, employment activity, level of education, age, and number and sites of lesions. Results: A total of 213 patients were included, of whom 30.98% were female and 69.02% were male. The main employment activity was agriculture (27.56%). The most common level of education was elementary (62.42%). The average age was approximately 39 years. The majority of the patients presented only with one lesion (54.87%), and legs/feet were the most commonly affected area (48.25%), followed by the arms/hands (44.75%). Conclusions: These data demonstrated that irrespective of the patients' places of origin, interventions need to be focused on men of economically productive age, in view of the high risk of exposure to the vector in this group. Education activities need to be directed to farmers about the importance of protection against ACL vectors during work. Such information must also be directed to employers as a way of implementing and maintaining appropriate working conditions and stepping up vector control.

“…No cases of spontaneously healing was seem probably because the short period of disease duration until the diagnosis establishment. The cases of L. (V.) naiffi reported herein underline that this species may not have a self-limiting nature, as previously described ( Naiff et al 1991 , van der Snoek et al 2009), and could not be as uncommon as referenced (Grimaldi Jr et al 1991, Figueira et al 2014 ). The present results highlight the importance of characterising Leishmania spp in areas that exhibit a sympatric circulation of Leishmania spp parasites to define the epidemiological importance of each of these species to human disease.…”

In the Brazilian Amazon, American tegumentary leishmaniasis (ATL) is endemic and presents a wide spectrum of clinical manifestations due, in part, to the circulation of at least seven Leishmania species. Few reports of Leishmania (Viannia) naiffi infection suggest that its occurrence is uncommon and the reported cases present a benign clinical course and a good response to treatment. This study aimed to strengthen the clinical and epidemiological importance of L. (V.) naiffi in the Amazon Region (Manaus, state of Amazonas) and to report therapeutic failure in patients infected with this species. Thirty Leishmania spp samples isolated from cutaneous lesions were characterised by multilocus enzyme electrophoresis. As expected, the most common species was Leishmania (V.) guyanensis (20 cases). However, a relevant number ofL. (V.) naiffi patients (8 cases) was observed, thus demonstrating that this species is not uncommon in the region. No patient infected withL. (V.) naiffi evolved to spontaneous cure until the start of treatment, which indicated that this species may not have a self-limiting nature. In addition, two of the patients experienced a poor response to antimonial or pentamidine therapy. Thus, either ATL cases due to L. (V.) naiffi cannot be as uncommon as previously thought or this species is currently expanding in this region.

Justificativa e Objetivos: A Leishmaniose Cutânea Americana (LCA) é uma doença de cadeia de transmissão complexa sujeita a diversos determinantes, em uma mesma região. Este estudo teve como objetivo analisar o comportamento e determinar o perfil epidemiológico da LCA em uma região da Amazônia Sul-ocidental utilizando técnicas de análises multivariadas. Métodos: Utilizou-se as informações do Sistema de Informação de Agravos de Notificação (Sinan), 2001 a 2010,para o estado do Acre e técnicas de análises de agrupamento hierárquico e de componentes principais.Resultados: Foram analisados um total de 10.984 casos de LCA e discriminados três grupos. O primeiro grupo se destacou por apresentar maior porcentagem de indivíduos do sexo feminino, com predominância da forma clínica mucosa, idade até 20 anos, que residiam e trabalhavam em áreas rurais e florestais; o segundo grupo foi discriminado por agrupar indivíduos do sexo masculino, com forma clínica cutânea, idade superior a 40 anos de idade, que residiam e trabalhavam em áreas urbanas; o terceiro grupo foi constituído por indivíduos do sexo masculino, forma clínica cutânea, idades entre 20 e 40 anos, que residiam e trabalhavam em áreas rurais. Conclusão: Há evidências que para cada tipo de transmissão de LCA florestal, urbano e rural, exista um perfil epidemiológico correspondente e as técnicas de análises multivariadas foram eficientes em destacar o comportamento da LCA relacionando-os ao perfil dos indivíduos acometidos.
