Abstract
One of the potential dangers of American tegumentary leishmaniasis (ATL) caused by Leishmania (Viannia) braziliensis is the development of mucosal lesions. Haematogenous dissemination of the parasite is the most likely mechanism to explain this occurrence, but most attempts to isolate the parasite from blood have so far been unsuccessful. The presence of Leishmania in peripheral blood was therefore evaluated by PCR using DNA samples isolated from patients presenting active cutaneous or mucosal disease, and from individuals cured by antimonial treatment as well as individuals without a past history of leishmaniasis but with a positive Montenegro skin test, all living in L. (V.) braziliensis-endemic areas. Leishmania DNA was found not only in those patients presenting active cutaneous (24.8%) or mucosal (35%) lesions, but also in samples isolated from healed individuals (27.3%) as well as in asymptomatic skin-test-positive residents of endemic areas (37.5%). Overall, PCR showed the presence of parasite DNA in the blood of 26.2% of the 225 examined samples. These data suggest that persistence of parasites within the host may last for many years and, rather than being a risk factor, might be important in maintaining the protective response in those living in endemic areas.

Abstract
We performed a serological study with sera from 92 patients with confirmed sporotrichosis registered between 1999 and 2004 in two hospitals in Rio de Janeiro State, Brazil. The clinical presentation of sporotrichosis was distributed as follows: lymphocutaneous, 67%; fixed cutaneous, 23%; disseminated cutaneous, 8%; and extracutaneous, 2%. Sera were assayed by ELISA against a cell wall antigen of Sporothrix schenckii, SsCBF, that we have previously described. The cross-reactivity was determined with 77 heterologous sera. The serological test showed a sensitivity of 90% and a global efficiency of 86%. A group of 55 patients with several clinical presentations of sporotrichosis was clinically and serologically followed-up for at least 6 months. We observed by ELISA data a decrease in the antibody serum titers which correlated with the progress in healing. An HIV-positive patient with meningeal sporotrichosis was serologically followed-up for over 2 years. Serum and cerebrospinal fluid specimens were examined and significant antibodies levels against the antigen SsCBF were detected. Our results strongly suggest that this serological test is valuable for the differential diagnosis and follow-up of all clinical forms of sporotrichosis.

Abstract
Paniculite eosinofílica pode ser desencadeada por muitos fatores; aqui os autores descrevem a síndrome em conseqüência de injeções intramusculares de compostos de antimônio para tratamento de leishmaniose tegumentar americana em três pacientes. Todos eles desenvolveram lesões em placa, profundamente infiltradas, no local da injeção antimonial. A histopatologia mostrou acentuado infiltrado inflamatório da hipoderme com numerosos eosinófilos. O estudo imunológico não demonstrou imunoglobulinas ou frações do complemento nas lesões. O diagnóstico final foi de paniculite eosinofílica ocorrendo como efeito colateral da terapia antimonial. O mecanismo patogênico dessa paniculite não pôde ser definido. As hipóteses sugeridas foram de lesão induzida por fenômeno físico - a pressão exercida pelo volume do líquido injetado - ou de uma reação alérgica ao antimônio.

Abstract
Sporotricosis is a ubiquitous mycosis characterized by nodular lesions of the cutaneous or subcutaneous tissues and adjacent lymphatics that usually suppurate and ulcerate. Secondary spread to the articular surface and bone or dissemination to the central nervous system, genitourinary tract or lungs is also possible. All forms of sporothricosis are caused by a single species, Sporothrix schenkii. In the great majority of cases the fungus gains entrance into the body through trauma to the skin with some kind of plant materials such as thorns or splinters. Zoonotic transmission is also possible and several animals are implicated. This kind of transmission is most frequently a professional hazard of people dealing with animals but in some parts of the world, including Rio de Janeiro city and metropolitan region, an increase in transmission by pet cats has been noted. In these cases the infection may be observed in the family environment, an important epidemiological consideration to clinicians.

Abstract
T-cell immune responses in patients with cutaneous leishmaniasis (CL) and mucosal leishmaniasis (ML) were studied during the active disease, at the end of therapy, and 1 to 17 years posttherapy (long-term follow-up). Lymphocyte proliferative responses, phenotypic characterization of CD4(+) and CD8(+) Leishmania-reactive T cells, and cytokine production were assayed. Patients with active ML and CL showed higher proportions of CD4(+) than CD8(+) T cells. In CL, the healing process was associated with a decrease of CD4(+) and an increase of CD8(+), leading to similar CD4(+) and CD8(+) proportions. This pattern was only seen in ML after long-term therapy. Long-term follow-up of patients with CL showed a positive CD4(+)/CD8(+) ratio as observed during the active disease, although the percentages of these T cell subsets were significantly lower. Patients with CL did not show significant differences between gamma interferon (IFN-gamma) and interleukin-5 (IL-5) production during the period of study. Patients with active ML presented higher IFN-gamma and IL-5 levels compared to patients with active CL. IL-4 was only detected during active disease. Patients long term after cure from ML showed increasing production of IFN-gamma, significant decrease of IL-5, and no IL-4 production. Two apparently beneficial immunological parameters were detected in tegumentary leishmaniasis: (i) decreasing proportions of CD4(+) Leishmania-reactive T cells in the absence of IL-4 production associated with cure of CL and ML and (ii) decreasing levels of IL-5 long after cure, better detected in patients with ML. The observed T-cell responses maintained for a long period in healed patients could be relevant for immunoprotection against reinfection and used as a parameter for determining the prognosis of patients and selecting future vaccine preparations.

Abstract
Response to treatment with antimonial drugs varies considerably depending on the parasite strain involved, immune status of the patient and clinical form of the disease. Therapeutic regimens with this first line drug have been frequently modified both, in dose and duration of therapy. A regimen of 20 mg/kg/day of pentavalent antimony (Sb5+) during four weeks without an upper limit on the daily dose is currently recommended for mucosal disease ("espundia"). Side-effects with this dose are more marked in elderly patients, more commonly affected by this form of leishmaniasis. According to our experience, leishmaniasis in Rio de Janeiro responds well to antimony and, in cutaneous disease, high cure rates are obtained with 5 mg/kg/day of Sb5+ during 30 to 45-days. In this study a high rate of cure (91.4%) employing this dose was achieved in 36 patients with mild disease in this same geographic region. Side-effects were reduced and no antimony refractoriness was noted with subsequent use of larger dose in patients that failed to respond to initial schedule.

Abstract
BACKGROUND Leishmaniasis recidiva cutis (LRC) is rare in New World leishmaniasis. Only seven cases have been reported so far. MATERIALS AND METHODS Four cases are reported here. Parasite diagnosis was performed by classical methods of touch preparations, histopathologic sections, and cultures. In addition, the detection of parasite DNA by the polymerase chain reaction (PCR) was performed in all cases. RESULTS Parasites were detected by at least one of the classical methods in all primary lesions; however, only the PCR was positive in the recidivant lesions. DISCUSSION LRC cases most likely represent a reactivation of an initial infection, probably due to the persistence of parasites in scarred tissue. Although lupoid leishmaniasis (LL) has been used as a synonym of LRC, a clear difference between LRC and LL can be defined as LL is the initial clinical presentation while LRC is a recurrent lesion. CONCLUSIONS The results indicate that it is not appropriate to use these two denominations as synonyms. The designation of LRC should be maintained in order to define recidives occurring at the border of an old scar of cutaneous leishmaniasis, avoiding the confusion with the lupoid form of the disease.

Abstract
OBJECTIVE A report of four cases of American cutaneous leishmaniasis associated with HIV infection is presented. BACKGROUND The association of mucocutaneous leishmaniasis and HIV infection is rare. Only 15 cases have been reported in the literature thus far. SUBJECTS Four new cases are described and the differences between the clinical presentation in immunocompromised and immunocompetent patients are emphasized. CONCLUSIONS Multiple cutaneous lesions plus mucosal involvement characterize the clinical presentation of American cutaneous leishmaniasis in association with HIV infection in the majority of the cases. A serological investigation for HIV infection is recommended for patients presenting with this type of clinical picture, especially if the patient is a young male.

Abstract
The efficacy of an antimony regimen at the dose of 20 mg/kg/day for a 3-4-week period is well established in the treatment of American cutaneous leishmaniasis. Several drug side effects, however, have been described and the search for more suitable regimens is advisable. In the present paper, the effect of a low dose (5 mg/kg/day for 30 days) of antimony was evaluated in 159 individuals from endemic regions of Rio de Janeiro State, Brazil, an area of Leishmania (V.) braziliensis transmission. Patients presented typical cutaneous lesions and parasites were demonstrated in all cases. One hundred forty-three patients were available for evaluation and of these, 120 (84%) were cured by the end of therapy. Twenty-three patients (16%) were considered treatment failures. Side effects were observed in only six patients (4%). Extensive follow-up (up to 10 years) disclosed no relapses or mucosal lesions. The results show that a low dose of antimony is less toxic, more appropriate, especially in children and elderly people, and has the same final result as that obtained with larger doses.

Abstract
BACKGROUND The drug of choice for leishmaniasis is pentavalent antimony and different regimens are under continuous evaluation. The ideal therapy should be simple, effective, and with no or minor side-effects. In this paper we have studied the efficacy of intralesionally applied antimony in New World cutaneous leishmaniasis. METHODS Seventy-four patients from Rio de Janeiro state, Brazil, and presenting with single ulcerative cutaneous lesions mainly located on the trunk or extremities were enrolled in the study. The drug employed was N-methyl glucamine (425 mg of Sbv in each 5 ml ampoule). Each lesion was infiltrated with the drug at the four cardinal points in order to achieve complete blanching. RESULTS Of the 74 patients, 59 (80%) were healed after a 12-week interval. Extensive follow-up (up to 10 years) disclosed no relapses or the development of mucosal lesions. CONCLUSIONS The aim of therapy in New World cutaneous leishmaniasis is the healing of the cutaneous lesion and the prevention of late mucosal damage. Both conditions were achieved with the treatment employed with no side-effects and a considerable decrease in costs. In addition, the method is easy to apply in the field.

Abstract
Twenty-three patients from Rio de Janeiro, Brazil-an area of Leishmania (Viannia) braziliensis transmission-were randomly assigned to receive either a high dose (20 mg/kg/day) of antimony or a lower one (5 mg/kg/day) in a 30 days series. The two treatment regimens showed similar responses. In 10 out of 12 patients receiving a dose of 5 mg/kg/day and 9 out of 11 patients with a dosage of 20 mg/kg/day a complete epithelization was noted by the end of treatment. In addition patients were followed for up to 7 years. No reactivation or development of mucosal lesions were observed in both groups during the extensive follow-up. We think that a low dosage of antimony could be equally effective than a higher one, at least in the presence of the clinical picture usually seen in Rio de Janeiro.
