This work reports the results of sandfly collections in several places, during 2001 and 2002, in Bom Sucesso, Jardim Alegre, Kaloré, Londrina and Sabáudia municipalities, North of the State. The sandflies catches were performed with Shannon and Falcão traps in domiciliary areas, domestic animal shelters, barns and in the forest. A total of 4,019 specimens of 8 species were captured. Nyssomyia whitmani predominates in all of the municipalities. The species Migonemyia migonei, Nyssomyia neivai and N. whitmani may be involved in the epidemiology of American Tegumentary Leishmaniasis in this state.

The purpose of this work was to verify the occurrence of Leishmania in naturally infected sandflies. The insects were collected with Falcão, Shannon and HP light-traps, in Doutor Camargo and Maringá municipalities between November 2004 and October 2005. Of the 11,033 sandflies collected in Doutor Camargo, 2,133 surviving females were dissected, particularly those of the Nyssomyia neivai species (86.87%). In Maringá, 136 sandflies were collected, of which 79 N. whitmani females and 1 Migonemyia migonei female were dissected. The dissected insects were identified and stored in the pools of 10 specimens. The PCR was carried out on 1,190 females of N. neivai and 190 of N. whitmani from Doutor Camargo, and on 30 of N. whitmani from Maringá, using the primers...

OBJECTIVE: To evaluate clinical, epidemiological and laboratorial aspects for the understanding of the disease characteristics and its relationship with diagnostic tests. METHODS: A retrospective, descriptive and analytical study involving 2,660 American cutaneous leishmaniasis (ACL) suspected patients from southern Brazil was undertaken between April 1986 and December 2005. Data on population characteristics and laboratory tests were obtained. Diagnostic laboratory tests used were direct search for Leishmania spp. (DS), Montenegro skin test (MST) and indirect immunofluorescent assay (IFA). RESULTS: 62.3% of patients were positive for at least one laboratory test. DS test was positive in 65.1%; MST in 92.3% and IFA in 70.0%. Although Cohen's Kappa test did...

American cutaneous leishmaniasis (ACL) is an endemic disease caused by Leishmania parasites. The ACL diagnosis is commonly accomplished by parasitological and immunological methods. The objective of this work was to evaluate the enzyme immunoassay (EIA) for ACL laboratorial diagnosis. IgG antibodies against Leishmania (Viannia) braziliensis promastigotes were researched. For the method standardization 240 sera were used: 72 from patients with positive parasitological diagnosis, 38 from normal individuals and 113 from individuals with other pathologies. The sensibility was 93% and the specificity was 70%. Regarding diagnosis, EIA showed 97% positivity in patients with ACL and 97% negativity in patients with other cutaneous lesions. The EIA presented a good...

The purpose of this study was to investigate the relationship of several variables to the healing of lesions in patients with American cutaneous leishmaniasis (ACL). The patients with clinical and/or laboratorial diagnoses of the disease were followed up for varying periods after treatment by clinical evaluation and indirect immunofluorescence assay (IFA), from September 2000 to December 2003. The lesions of 85.3% of the 163 patients had healed by their last return for clinical evaluation, and of these, 82.7% had negative IFA results, indicating an association between the healing of lesions and IFA negativity (p=0.000). In patients evaluated up to 120 days after treatment, there was a significant association between negative IFA results and the healing of...

Activity of antiretroviral drugs in human infections by opportunistic agents

Highly active antiretroviral therapy (HAART) is used in patients infected with HIV. This treatment has been shown to significantly decrease opportunist infections such as those caused by viruses, fungi and particularly, protozoa. The use of HAART in HIV-positive persons is associated with immune reconstitution as well as decreased prevalence of oral candidiasis and candidal carriage. Antiretroviral therapy benefits patients who are co-infected by the human immunodeficiency virus (HIV), human herpes virus 8 (HHV-8), Epstein-Barr virus, hepatitis B virus (HBV), parvovirus B19 and cytomegalovirus (CMV). HAART has also led to a significant reduction in the incidence, and the modification of characteristics, of bacteremia by etiological agents such as...
