| Visceral leishmaniasis (VL) is a cosmopolitan parasitic zoonosis that can promote myocarditis and heart rate changes in canine and human hosts. Thus, histopathological aspects of the myocardium and clinical, hematological, biochemical, radiological and electrocardiographic data were evaluated in a group of 36 dogs naturally infected with VL (VLG) and compared to data from 15 non-infected dogs (CG=Control Group). A prevalence of asymptomatic dogs was present in the CG (100%) and polysymptomatic dogs in the VLG (66%). In addition, two dogs in the VLG demonstrated systolic murmurs in the mitral valve region: one with a II/VI intensity and the other with a III/VI intensity. The mean values of RBC, hemoglobin and hematocrit were lower in dogs in VLG and were... |

| Leishmaniasis is a parasitic disease found in the continents of Europe, Asia, Africa and the Americas. In Brazil, the disease is an important public health problem, occurring in most states, but mainly in the Northeast region of the country, with the state of Alagoas having a significant number of confirmed cases. The present study establishes and discusses the epidemiological profile of cases of leishmaniases treated at the Reference Center of Alagoas, Hospital Escola Hélvio de Farias Auto, between January 2000 and October 2008. During thisperiod, records of 2,104 patients notified to the hospital Epidemiological Surveillance Center were reviewed. The epidemiology of leishmaniasis, both visceral and tegumentary, has shown a profile that has changed over... |

| In Brazil, sophisticated techniques currently employed for diagnosis of visceral leishmaniasis, such as polymerase chain reaction-based assays, are only available in major research centers, whereas conventional methods are still used in many areas where the disease occurs. In the state of Mato Grosso do Sul, in the country's Center-West Region, visceral leishmaniasis has recently emerged in many cities, and duration of the disease, from the onset of symptoms to diagnosis, has been short. Considering that results of diagnostic tests may depend on the phase of the disease, we compared direct examination of bone marrow aspirates (BMAs), BMA culture, and serology by Indirect Immunofluorescence Antibody Test (IFAT) for diagnosis in children, according to time... |

| Visceral leishmaniasis is an endemic disease caused by various species of Leishmania. We made a retrospective study of 57 consecutive patients with visceral leishmaniasis in Brazil. Patients with visceral leishmaniasis were identified using the registries of the São José Infectious Diseases Hospital. The sample was divided into two groups: patients with serum creatinine (Scr) <1.3mg/dL and Scr > 1.3mg/dL. We compared these two groups for differences in clinical manifestations and laboratory features. Patients' mean age was 28 ± 18 years old; 74% were male. The main clinical symptoms and signs presented in the initial evaluation were: fever (97%), splenomegaly (96.4%), weight loss (95.5%), pallor (93.6%), cough (89.7%), hepatomegaly (87.2%), asthenia... |

| Post-kala-azar dermal leishmaniasis (PKDL) is rarely reported in South America. In spite of the fact that there are many reports about the association of visceral leishmaniasis and AIDS, PKDL is very uncommon in HIV-positive patients, and so far only four cases have been documented in the literature. We present another case with unusual clinicopathological aspects. The patient, a 28-year-old male, from Salvador, Bahia (an endemic area) presented with clinical manifestations of visceral leishmaniasis three years after the diagnosis of AIDS. During treatment for visceral leishmaniasis he developed disseminated miliary papules. Microscopically, the skin biopsy showed a "saw-tooth" pattern with a lichenoid mononuclear infiltrate simulating lichen planus. The... |

| This is a case report of a 29 year old male with pneumocystis pneumonia and tuberculosis, and who was initially suspected of having HIV infection, based on risk factor analyses, but was subsequently shown to be HIV negative. The patient arrived at the hospital with fever, cough, weight loss, loss of appetite, pallor, and arthralgia. In addition, he was jaundiced and had cervical lymphadenopathy and mild heptosplenomegaly. He had interstitial infiltrates of the lung, sputum smears positive for Mycobacterium tuberculosis and Pneumocystis carinii, and stool tests were positive for Strongyloides stercoralis and Schistosoma mansoni. He was diagnosed as having AIDS, and was treated for tuberculosis, pneumocystosis, and strongyloidiasis with a good response. The... |

| ABSTRACT Visceral leishmaniasis is a serious and debilitating infection with high fatality rate in tropical and subtropical countries. As clinical symptoms of visceral leishmaniasis are not so specific, confirmatory diagnostic methods with high sensitivity and specificity are needed. Noninvasive methods have been developed using urine as a clinical sample for visceral leishmaniasis diagnosis. In fact, there is a clear correlation between kidney impairment and Leishmania DNA in urine. However, it has been proved that Leishmania nucleic acid may also be isolated from patients without any sign of renal involvement. Even though urine has become a promissing biological sample, it is still not widely used due to several issues, such as (i) incomprehension of the... |

| ABSTRACT Human visceral leishmaniasis is a growing anthropozoonosis in Brazil, and particularly in the southern region of the country. It is an infectious disease transmitted to humans, dogs and other animals in urban and rural areas of the Americas, mainly due to the bite of Lutzomya longipalpis infected with Leishmania infantum. This article aims to portray the current epidemiological situation of the human visceral leishmaniasis arrival in Porto Alegre city, located in the southern region of Brazil. It is a descriptive study, a case series and a critical review. Six human cases with human visceral leishmaniasis were notified by the date of conclusion of the study, all human visceral leishmaniasis cases were diagnosed at late stage, leading to four deaths. |

| Activation of Th1 or Th2 cells is associated with production of specific immunoglobulin isotypes, offering the opportunity to use antibody measurement for evaluation of T cell function. Schistosomiasis and visceral leishmaniasis are diseases associated with Th2 activation. However, an IgE response is not always detected in these patients. In the present study we evaluated specific IgE antibodies to S. mansoni and L. chagasi antigens by ELISA after depletion of serum IgG with protein G immobilized on Sepharose beads or RF-absorbent (purified sheep IgG antibodies anti-human IgG). In schistosomiasis patients, specific IgE to SWAP antigen was demonstrable in only 10 of 21 patients (48%) (mean absorbance ± SD = 0.102 ± 0.195) when unabsorbed serum was used.... |

| Leishmaniasis is a disease caused by protozoa of the genus Leishmania, and visceral leishmaniasis is a form in which the inner organs are affected. Since knowledge about immunity in experimental visceral leishmaniasis is poor, we present here a review on immunity and immunosuppression in experimental visceral leishmaniasis in mouse and hamster models. We show the complexity of the mechanisms involved and differences when compared with the cutaneous form of leishmaniasis. Resistance in visceral leishmaniasis involves both CD4+ and CD8+ T cells, and interleukin (IL)-2, interferon (IFN)- gamma, and IL-12, the latter in a mechanism independent of IFN- gamma and linked to transforming growth factor (TGF)-ß production. Susceptibility involves IL-10 but not IL-4,... |

| Visceral leishmaniasis in Brazil is caused by Leishmania (Leishmania) chagasi and the dog is its most important reservoir. The clinical features in dogs include loss of weight, lymphadenopathy, renal failure, skin lesions, fever, hypergammaglobulinemia, hepatosplenomegaly, anemia, and, rarely, neurological symptoms. Most infected animals develop active disease, characterized by high anti-leishmania antibody titers and depressed lymphoproliferative ability. Antibody production is not primarily important for protection but might be involved in the pathogenesis of tissue lesions. An ELISA test was used to determine if there is an association between neurological symptoms and the presence of anti-L. chagasi antibodies in cerebrospinal fluid (CSF). Thirty serum... |
