    ABSTRACT: A case of mucosal leishmaniasis in a 60-year old hemodialysis patient who had never lived outside Italy is described. The patient complained of fever, epistaxis and nasal obstruction. An anterior rhinoscopy disclosed a mass of two centimetres in diameter in the right nasal fossa. Histological examination revealed Leishmania amastigotes. Serology for Leishmania was positive with antibody titer of 1/320. A culture yielded a very slow growth of Leishmania infantum MON-24. In spite of a two-month treatment with oral itraconazole, the lesions progressively worsened. Treatment with topical paromomycin sulfate determined the complete resolution of the lesions within four months, with a residual perforation of the septum. This case demonstrates that localization of Leishmania spp must be considered in the differential diagnosis of mucosal lesions in hemodialyzed patients, even in countries not at risk for this parasite. Moreover, this case indicates the important role of the immune system in the evolution of the disease.

    ABSTRACT: To investigate the response of HIV-associated severe thrombocytopenia (STP) to highly active antiretroviral therapy (HAART) including protease-inhibitors. In this retrospective study, 15 patients with HIV-associated STP (platelet count < 50 x 10(9)/l mostly antiretroviral experienced (13/15), underwent HAART for at least 6 months (median 21; range 6-41 months) during which the platelet (PLT) count and plasmatic HIV-RNA were monitored. The PLT response was compared to that observed in 19 patients previously treated with zidovudine (AZT) monotherapy. HAART induced a significant increase in the PLT count (chi(2)=10.53, P=0.01) within the third month which was sustained up to the sixth month of therapy. No STP relapse was observed among eight PLT responders followed for longer than 6 months (median 27; range 7-41 months). The PLT increase after HAART was similar to that observed with AZT monotherapy, but a greater number of HAART patients were antiretroviral-experienced. HAART determined a PLT response in 10/13 subjects whose thrombocytopenia had not improved after previous AZT monotherapy. After 6 months of HAART, a complete platelet response occurred more frequently in patients with undetectable plasma HIV-RNA levels (P=0.01). HAART induces a sustained PLT response in HIV-associated STP, even in antiretroviral-experienced subjects and in those with AZT-resistant thrombocytopenia. An undetectable plasma HIV viraemia induced by HAART is necessary for STP recovery.

    ABSTRACT: To evaluate the presence of premature atherosclerotic lesions of epiaortic vessels in HIV-1-infected protease inhibitor-(PI) treated patients compared with PI-naive patients and healthy individuals. One-hundred and two HIV-1-positive patients, including 55 treated with PI for at least 12 months and 47 either naive or treated with PI-sparing regimens, were subjected to epiaortic vessel ultrasonography. These data were compared with those obtained from 104 healthy individuals. Intima characteristics, pulsation and resistance indexes, and minimal, peak and mean speed were evaluated using a colour power doppler. Atherosclerotic plaques were described. Independent risk factors and values for glycaemia, cholesterolaemia and triglyceridaemia were considered. Statistical analysis included the chi-square test, Mantel-Haenszel test, odds ratio and logistic regression analysis. Of the PI-treated patients, 29 out of 55 (52.7%) presented acquired lesions of the vascular wall at ultrasonography, whereas similar lesions were found in seven out of 47 (14.9%) PI-naive patients. Of the 104 healthy individuals, seven cases (6.7%) of intimal medial thickness were noted. A slightly significant correlation was found between carotid lesions and age, male sex and hypercholesterolaemia, whereas cigarette smoking, hypertriglyceridaemia and Centers for Disease Control and Prevention stage significantly increased the risk of vascular lesions (P= 0.022, P= 0.017 and P= 0.079 respectively). However, the highest significance regarded use of PI (P= 0.011). These results were confirmed by logistic regression analysis. These data demonstrate a higher than expected prevalence of premature carotid lesions in the PI-treated compared with PI-naive patients. If confirmed, a periodic ultrasonographic study of the vascular wall should be included in the follow-up of HIV infected patients.

    ABSTRACT: Mycobacterium terrae has been rarely implicated in human disease and never in patients infected with human immunodeficiency virus (HIV). We describe an HIV-infected patient with disseminated infection by M. terrae with pulmonary and cutaneous clinical manifestations. M. terrae was isolated from both sputum and urine, and identified by both conventional tests and high-performance liquid chromatography. Clinical and microbiological characteristics of this case are compared with those reported in the literature.

    ABSTRACT: The localization of opportunistic infections in the basal ganglia in patients with acquired immunodeficiency syndrome (AIDS) can cause movement disorders, such as choreoathetosis, dystonia, hemiballism and, more rarely, parkinsonism. We describe the case of an AIDS patient who developed cerebral opportunistic granulomatous lesions and, subsequently, a parkinsonian akinetic-rigid syndrome. In agreement with cases reported in the literature, the parkinsonian syndrome developed only when the lesions bilaterally involved basal ganglia. The critical localization of the opportunistic lesions in the direct and indirect strio-pallidal pathways possibly associated with the HIV-related neurotoxicity might have contributed to determine this clinical picture.
