Human T-cell leukemia virus type 1 (HTLV-1), the first human retrovirus to be discovered, is present in diverse regions of the world, where its infection is usually neglected in health care settings and by public health authorities. Since it is usually asymptomatic in the beginning of the infection and disease typically manifests later in life, silent(More)
HTLV-1 associated myelopathy/ tropical spastic paraparesis (HAM/TSP) is a systemic immune-mediated inflammatory disease and tissues other than nervous can be damaged, mainly ocular, rheumatic and dermatologic. Over 90% of HTLV-1-infected individuals remain lifelong asymptomatic and this retrovirus persists indefinitely in their CD4+ T-lymphocytes. The(More)
UNLABELLED Caloric testing is an otoneurologic evaluation of the status of the vestibular-ocular reflex; it allows an evaluation of each labyrinth separately. The main aspects on the use and interpretation of caloric testing are reviewed. METHOD A systematic review of papers published in the past one hundred years on caloric testing was undertaken. The(More)
The development of HTLV-1-associated myelopathy (HAM/TSP) in HTLV-1-infected individuals is probably a multi-factor event, in which the immune system plays a crucial role. The efficiency of the host immunity seems to be one of the in vivo determining factors of the proviral load levels and is regulated by genes associated with MHC class I alleles (HLA).(More)
Dermatologic manifestations are quite common in patients with adult T cell leukemia/lymphoma and myelopathy/tropical spastic paraparesis associated with infection with human T cell lymphotropic virus type-1 (HTLV-1). In this study, we evaluated the dermatologic lesions of eligible blood donors in the state of Minas Gerais in Brazil who were seropositive but(More)
When present for a first time blood donation, a 28-year-old Brazilian white female reported a pruritic eczema of the scalp and retroauricular areas since childhood that had been frequently infected. Her mother had been diagnosed as having HTLV-I-associated myelopathy (HAM), and the patient was found to be a human T-lymphotropic virus type-I (HTLV-I)(More)
In the present study, the frequency, the activation and the cytokine and chemokine profile of HTLV-1 carriers with or without dermatological lesions were thoroughly described and compared. The results indicated that HTLV-1-infected patients with dermatological lesions have distinct frequency and activation status when compared to asymptomatic carriers.(More)
UNLABELLED Mucocutaneous Leishmaniasis (ML) can lead to serious sequela; however, early diagnosis can prevent complications. AIM To evaluate clinical markers for the early diagnosis of ML. MATERIALS AND METHODS A series study of 21 cases of ML, which were evaluated through clinical interview, nasal endoscopy, biopsy and the Montenegro test. RESULTS A(More)
The serodiagnosis of human tegumentary leishmaniasis (TL) presents some problems, such as the low level of antileishmanial antibodies found in most of the patients, as well as the cross-reactivity in subjects infected by other trypanosomatids. In the present study, an immunoproteomic approach was performed aimed at identification of antigens in total(More)
Human tegumentary leishmaniasis (HTL), characterized by skin ulcers that may spread and cause dreadful and massive tissue destruction of the nose and mouth, is considered a neglected tropical disease, and it is a serious threat to global health due to its continuous expansion, favored by the lifecycle of its causative organism that is maintained in domestic(More)
