RÉSUMÉ

BACKGROUND Epidemiological data related to leishmaniases or Leishmania infection in horses are scarce. However, studies carried out in different regions in the world showed equids parasitised by Leishmania braziliensis, L. infantum and L. martiniquensis. OBJECTIVES Identify the Leishmania species causing cutaneous leishmaniasis in a mare, living in Rio de Janeiro State (Brazil), and search the presence of Leishmania viruses in the isolated parasite. METHODS Isoenzymes and polymerase chain reaction (PCR) targeting ITSrDNA region followed by sequencing were conducted for typing the isolated parasite. A search for Leishmania virus infection was also performed. FINDINGS The mare presented skin nodules and ulcers in the left pinna caused by Leishmania spp. that was detected by culture and PCR. The parasite was identified as Leishmania (Mundinia) martiniquensis, infected by Leishbunyavirus (LBV), representing the first description of this species in South America. The animal travelled to different Brazilian regions, but not to outside the country. MAIN CONCLUSIONS The worldwide distribution of L. martiniquensis and its infection by LBV were confirmed in this study, indicating the autochthonous transmission cycle in Brazil. The clinical profile of the disease in the mare, showing fast spontaneous healing of cutaneous lesions, may indicate that skin lesions related to L. martiniquensis infection in horses might be underdiagnosed.

RÉSUMÉ

BACKGROUND Cutaneous leishmaniasis (CL) generally presents with a single or several localised cutaneous ulcers without involvement of mucous membranes. Ulcerated lesions are susceptible to secondary contamination that may slow the healing process. OBJECTIVE This study verified the influence of non-parasitic wound infection on wound closure (epithelialisation) and total healing. METHODS Twenty-five patients with a confirmed diagnosis of CL and ulcerated lesions underwent biopsy of ulcer borders. One direct microbial parameter (germ identification in cultures) and four indirect clinical parameters (secretion, pain, burning sensation, pruritus) were analysed. FINDINGS Biopsies of ten lesions showed secondary infection by one or two microorganisms (Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis, Streptococcus pyogenes and Candida parapsilosis). "Secretion" and "burning sensation" influenced epithelialisation time but not total healing time. Positive detection of germs in the ulcer border and "pain" and "pruritus" revealed no influence on wound closure. CONCLUSIONS Our borderline proof of clinical CL ulcer infection inhibiting CL wound healing supports the need to follow antimicrobial stewardship in CL ulcer management, which was recently proposed for all chronic wounds.

RÉSUMÉ

SUMMARY American tegumentary leishmaniasis (ATL) is an infectious disease caused by protozoa of the genus Leishmania, and transmitted by sandflies. In the state of Rio de Janeiro, almost all of the cases of American tegumentary leishmaniasis (ATL) are caused by Leishmania (Viannia) braziliensis, while cases of visceral leishmaniasis (VL) are caused by Leishmania (Leishmania) infantum chagasi. The resurgence of autochthonous VL cases in Rio de Janeiro is related to the geographic expansion of the vector Lutzomyia longipalpis and its ability to adapt to urban areas. We report the first case of leishmaniasis with exclusively cutaneous manifestations caused by L. (L.) infantum chagasi in an urban area of Rio de Janeiro. An eighty-one-year-old woman presented three pleomorphic skin lesions that were not associated with systemic symptoms or visceromegalies. Multilocus enzyme electrophoresis identified L. (L.) infantum chagasi, but direct smear and PCR of bone narrow were negative for Leishmania sp. (suggesting exclusively cutaneous involvement). We discuss the different dermatological presentations of viscerotropic leishmaniasis of the New and Old World, and the clinical and epidemiological importance of the case. Etiologic diagnosis of ATL based upon exclusive clinical criteria may lead to incorrect conclusions. We should be aware of the constant changes in epidemiological patterns related to leishmaniases.


RESUMO A leishmaniose tegumentar americana (LTA) é uma doença infecciosa causada por protozoários do gênero Leishmania, transmitida por flebotomíneos. No estado do Rio de Janeiro, quase todos os casos de LTA são causados por Leishmania (Viannia) braziliensis, enquanto a leishmaniose visceral (LV) é causada por Leishmania (Leishmania) infantum chagasi. O ressurgimento de casos autóctones de LV no Rio de Janeiro está relacionado com a expansão geográfica dos vetores Lutzomyia longipalpis e à sua capacidade de se adaptar às áreas urbanas. Relatamos o primeiro caso de leishmaniose com manifestações exclusivamente cutâneas causadas por L. (L.) infantum chagasiem uma área urbana do Rio de Janeiro. Mulher de 81 anos apresentou três lesões cutâneas pleomórficas não associadas a sintomas sistêmicos ou visceromegalias. A eletroforese de enzimas multilocus obtida a partir da lesão cutânea identificou L. (L.) infantum chagasi,por outro lado o exame direto e o PCR da medula óssea foram negativos para Leishmaniasp. (sugerindo acometimento exclusivamente cutâneo). Discutimos as diferentes apresentações dermatológicos da leishmaniose visceral do Novo e Velho Mundo, assim como a importância clínica e epidemiológica deste caso. O diagnóstico etiológico da LTA com base apenas em critérios clínicos pode levar a conclusões incorretas. Devemos estar conscientes das constantes mudanças nos padrões epidemiológicos relacionados à leishmaniose.

RÉSUMÉ

A case-control study was conducted to examine the association among the Montenegro skin test (MST), age of skin lesion and therapeutic response in patients with cutaneous leishmaniasis (CL) treated at Evandro Chagas National Institute of Infectious Diseases (INI), Oswaldo Cruz Foundation (FIOCRUZ), Rio de Janeiro, Brazil. For each treatment failure (case), two controls showing skin lesion healing following treatment, paired by sex and age, were randomly selected. All patients were treated with 5 mg Sb5+/kg/day of intramuscular meglumine antimoniate (Sb5+) for 30 successive days. Patients with CL were approximately five times more likely to fail when lesions were less than two months old at the first appointment. Patients with treatment failure showed less intense MST reactions than patients progressing to clinical cure. For each 10 mm of increase in MST response, there was a 26% reduction in the chance of treatment failure. An early treatment - defined as a treatment applied for skin lesions, which starts when they are less than two months old at the first appointment -, as well as a poor cellular immune response, reflected by lower reactivity in MST, were associated with treatment failure in cutaneous leishmaniasis.


Conduzimos estudo caso-controle que verificou a associação entre a intradermorreação de Montenegro (IDRM), o tempo de evolução da lesão e a resposta terapêutica em pacientes com leishmaniose cutânea (LC) atendidos no Instituto de Infectologia Evandro Chagas (INI), Fundação Oswaldo Cruz (Fiocruz), Rio de Janeiro, Brasil. Para cada caso com má resposta à terapêutica foram selecionados aleatoriamente dois controles que evoluíram com cicatrização das lesões após o tratamento, pareados por sexo e idade. Todos os pacientes realizaram tratamento com antimoniato de meglumina (Sb5+) IM, na dose de 5 mg Sb5+/kg/dia, continuamente, por 30 dias. Pacientes com LC apresentaram aproximadamente cinco vezes mais chance de falhar quando as lesões apresentavam menos de dois meses de evolução no primeiro dia de atendimento. Pacientes com falha terapêutica apresentaram reações de IDRM menos intensas que pacientes que evoluíram para a cura clínica. A cada 10 milímetros de aumento na resposta à IDRM, houve uma redução de 26% na chance de ocorrência de falha. O tratamento precoce, traduzido pelo tempo de evolução da lesão menor que dois meses no primeiro dia de atendimento, e resposta de imunidade celular deficiente, traduzida por IDRM menos intensa, demonstraram contribuir para a ocorrência de falha terapêutica na leishmaniose cutânea.

RÉSUMÉ

The diagnosis of asymptomatic infection with Leishmania (Leishmania) chagasi has become more important over recent years. Expansion of visceral leishmaniasis might be associated with other routes of transmission such as transfusion, congenital or even vector transmission, and subjects with asymptomatic infection are potential reservoirs. Moreover, the identification of infection may contribute to the management of patients with immunosuppressive conditions (HIV, transplants, use of immunomodulators) and to the assessment of the effectiveness of control measures. In this study, 149 subjects living in a visceral leishmaniasis endemic area were evaluated clinically and submitted to genus-specific polymerase chain reaction (PCR), serological testing, and the Montenegro skin test. Forty-nine (32.9%) of the subjects had a positive PCR result and none of them developed the disease within a follow-up period of three years. No association was observed between the results of PCR, serological and skin tests. A positive PCR result in subjects from the endemic area did not indicate a risk of progression to visceral leishmaniasis and was not associated with a positive result in the serological tests.


O diagnóstico de infecção assintomática por Leishmania (Leishmania) chagasi tem assumido crescente importância nos últimos anos. A expansão da leishmaniose visceral pode estar associada a outras vias de transmissão tais como transfusional, congênita, ou mesmo vetorial, sendo os indivíduos com infecção assintomática, potenciais reservatórios. Ademais, a identificação da infecção poderia auxiliar na condução dos pacientes com condições de imunossupressão (HIV, transplante, uso de imunomoduladores) e na avaliação da efetividade das medidas de controle. Neste estudo, foram avaliados clinicamente 149 indivíduos residentes em área endêmica de leishmaniose visceral e realizada a reação em cadeia da polimerase (PCR) gênero-específica, testes sorológicos e teste de Montenegro. Destes, 49 (32,9%) apresentaram PCR positiva, dos quais nenhum evoluiu com clínica de leishmaniose visceral nos três anos subsequentes. Não houve associação entre o resultado da PCR, dos exames sorológicos e do teste cutâneo. A positividade da PCR em indivíduos da área endêmica estudada não indicou risco de progressão para leishmaniose visceral e também não foi associada à maior positividade dos testes sorológicos.

RÉSUMÉ

The present study investigated the diagnostic value of polymerase chain reaction (PCR) performed in parallel to conventional methods at an American tegumentary leishmaniasis (ATL) referral centre for diagnosis. Accuracy parameters for PCR were calculated using 130 patients with confirmed ATL (ATL group), 15 patients established with other diseases and 23 patients with a lesion suggestive of ATL, but without parasitological confirmation (NDEF group). PCR showed 92.3 percent sensitivity, 93.3 percent specificity, a 99.2 percent positive predictive value and a 13.84 positive likelihood ratio. In the NDEF group, PCR confirmed ATL in 13 of the 23 patients, seven of whom responded to leishmaniasis treatment and six who presented spontaneous healing of the lesion. PCR should be included in the routine diagnostic procedures for ATL, especially for cases found to be negative by conventional methods.

RÉSUMÉ

From 1977 (index case) to 2006, 87 cases of visceral leishmaniasis were confirmed in the municipality of Rio de Janeiro, Brazil, in periurban areas on the continental and coastal slopes of the Pedra Branca massif and the continental slopes of the Gericinó massif. The majority (65.5 percent) of the patients were more than five years old, predominantly males (61.5 percent), but without any difference between the sexes below the age of 14 years. The overall fatality rate was 10.4 percent. Two cases of visceral leishmaniasis/human immunodeficiency virus coinfection were detected. Leishmania chagasi was isolated from human and canine cases. The associations between the presence of phlebotomines and human and canine migrations, disorderly occupation involving degradation of environmental preservation areas and poor socioeconomic conditions may have created a favorable setting for the establishment and propagation of the disease. Close epidemiological surveillance associated with traditional control measures and others (active case researches, land clearing and health education), reduced the incidence of human cases from 2.8 per 100,000 inhabitants in 1981 to less than 0.01 per 100,000 since 1997. The canine infection rates decreased from 4.6 percent in 1984 to 1.6 percent in 2008. Lutzomyia longipalpis was not detected in some locations where human and canine cases occurred. In the years 2007 and 2008, no new human cases were reported, but there is a persistent and worrisome residual canine seroprevalence.


Entre 1977 (caso índice) e 2006 foram confirmados 87 casos de leishmaniose visceral no Município do Rio de Janeiro, oriundos de áreas peri-urbanas das vertentes continentais e litorâneas do Maciço da Pedra Branca e das vertentes continentais do Maciço do Gericinó. A maioria (65,5 por cento) dos pacientes tinha mais de 5 anos de idade, prevalecendo o sexo masculino (61,5 por cento), sem diferença de freqüência entre os sexos até os 14 anos. A letalidade foi de 10,4 por cento. Houve dois casos de co-infecção por leishmaniose visceral/vírus da imunodeficiência. Leishmania chagasi foi isolada de casos humanos e caninos. Presença de flebotomíneos associada a migrações humanas e caninas, ocupação desordenada degradando áreas de preservação ambiental e baixas condições socioeconômicas podem ter criado o contexto propício à instalação e à propagação da endemia. Vigilância epidemiológica estreita com as medidas tradicionais de controle e outras - busca ativa de pacientes, limpeza de terrenos e educação em saúde -, reduziram a incidência de casos humanos de 2,8 por 100 mil habitantes em 1981 para menos de 0,01 por 100 mil a partir de 1997. As taxas de infecção canina decresceram de 4,6 por cento em 1984 para 1,6 por cento em 2008. Lutzomyia longipalpis não foi detectada em algumas localidades onde ocorreram casos humanos e caninos. Em 2007 e 2008, nenhum novo caso da doença humana foi notificado, mas permanece uma preocupante prevalência sorológica residual canina.

RÉSUMÉ

A restrição protéica neonatal causa baixo peso corporal, hipertireoidismo, hipoinsulinemia, aumento de glicocorticóides e de catecolaminas nos animais aos 180 dias. Assim, estudamos nestes animais durante o seu desenvolvimento, a composição corporal, lipídeos e proteínas no soro, além de alguns hormônios relacionados à homeostase glicêmica. Ao nascimento, dividimos as ratas lactantes em: controle (C) - alimentadas com ração comercial (23% de proteína) e RP - alimentadas com dieta hipoprotéica (8% de proteína). Após o desmame, os filhotes receberam dieta comercial. Os animais foram sacrificados em idades distintas (21, 90 e 80 dias). Os animais RP apresentaram baixa massa corporal desde a lactação até 180 dias, menor massa de gordura visceral e total (90 e 180 dias); menor conteúdo corporal de proteína e maior água corporal aos 21 dias. A morfologia dos adipócitos viscerais e subcutâneos aos 180 dias mostrou menor área e perímetro. Observamos menor massa, comprimento e diâmetro do fêmur em todas as idades estudadas. Detectamos maior conteúdo de glicogênio hepático (21 dias) e muscular (180 dias). Aos 21 dias, a insulinemia foi menor e a adiponectinemia foi maior. Aos 180 dias, detectamos menor insulina sérica e glicemia. Em relação à função adrenal, verificamos maior concentração de corticosterona sérica, maior conteúdo intra-adrenal e secreção in vitro de catecolaminas aos 180 dias. A prole RP apresentou: menores concentrações de proteínas totais e frações (21 dias), menor concentração de colesterol total (180 dias), maior concentração de LDL-c (21 dias), menores concentrações de VLDL-c e triglicerídeos (21 e 90 dias). Quanto à sinalização da leptina, observamos menor conteúdo de STAT3 no hipotálamo aos 180 dias. Na tireóide, estes animais apresentaram menor conteúdo de Ob-Rb (21 dias) e a expressão de JAK2 foi maior aos 21 dias e menor aos 180 dias de idade. Assim, a RP materna na lactação induz a uma desnutrição energético-protéica...


Neonatal protein restriction (PR) causes lower body weight, hyperthyroidism, hypoinsulinaemia, higher glucocorticoids and catecholamines in the adult rat offspring. In this model, we studied the body composition, serum lipids and proteins, as well as, some hormones related to glucose homeostasis in the offspring during development. At birth, lactating rats were divided into: control (C) - fed a normal diet (23% protein) and PR - fed a diet with 8% protein. After weaning, pups received normal diet. They were killed at distinct ages until the 21, 90 and 180 days-old. PR rats presented lower body weight since weaning until 180 days-old, lower visceral and fat mass (90th and 180th day), lower body protein and higher body water (21st day: +3%). At 180 days-old, the visceral and subcutaneous adipocytes morphology showed lower area and perimeter. Concerning the femur, we observed lower weight, length and width at all analized periods. We detected higher liver (21 days-old) and muscle glycogen content (180 days-old). At 21st day, insulinaemia was lower and adiponectinaemia was higher. At 180th day, we detected lower insulinaemia and glycaemia. Concerning adrenal function, we verified higher serum corticosterone, adrenal catecholamines content and in vitro secretion. PR offspring showed the following serum parameters: lower total protein serum and fractions (21st day), lower total serum cholesterol (180th day), higher serum LDL-c (21st day), lower serum VLDL-c and triglycerides (21st and 90st day). Regardind the leptin signaling, we observed lower hipothalamic STAT3 content at 180th day. In thyroid, these animals presented lower Ob-Rb content (21st day); JAK2 content was higher at 21st day and lower at 180th day. Thus, maternal PR during lactation induces an energy-protein malnutrition, characterized by an impairment of the pup's protein anabolism, and after weaning, the offspring showed lower central and total adiposity, suggesting a higher lipolitic activity...

RÉSUMÉ

The objective of the present study was to evaluate the specificity of the Montenegro skin test (MST) in an area in Brazil, state of Grande do Sul State (RS), which was considered to be non-endemic for leishmaniasis. Sixty subjects presented a positive MST and were reevaluated by clinical examination, serology and polymerase chain reaction (PCR) of peripheral blood for the detection of subclinical Leishmania infection. None of the subjects presented clinical signs or symptoms of current leishmaniasis or a history of the disease.Leishmania (Viannia) DNA was detected in blood by PCR and hybridization in one subject. The PCR skin test-positive individual remained asymptomatic throughout the study. Clinical examination showed no scars suggestive of past cutaneous leishmaniasis. Human subclinical infection with Leishmania (Viannia) in RS was confirmed by PCR. This is the first report of subclinical infection with this parasite in the human population of this area.
