Quantitative PCR as a marker for preemptive therapy and its role in therapeutic control in Trypanosoma cruzi/HIV coinfection.

Background: Trypanosoma cruzi and HIV coinfection can evolve with depression of cellular immunity and increased parasitemia. We applied quantitative PCR (qPCR) as a marker for preemptive antiparasitic treatment to avoid fatal Chagas disease reactivation and analyzed the outcome of treated cases.

Methodology: This mixed cross-sectional and longitudinal study included 171 Chagas disease patients, 60 coinfected with HIV.

Correction: Clinical profile and mortality in patients with T. cruzi/HIV co-infection from the multicenter data base of the "Network for healthcare and study of Trypanosoma cruzi/HIV co-infection and other immunosuppression conditions".

Clinical profile and mortality in patients with T. cruzi/HIV co-infection from the multicenter data base of the "Network for healthcare and study of Trypanosoma cruzi/HIV co-infection and other immunosuppression conditions".

Objective: Chagas disease (CD) globalization facilitated the co-infection with Human Immunodeficiency Virus (HIV) in endemic and non-endemic areas. Considering the underestimation of Trypanosoma cruzi (T. cruzi)-HIV co-infection and the risk of life-threatening Chagas Disease Reactivation (CDR), this study aimed to analyze the major co-infection clinical characteristics and its mortality rates.

Echocardiographic Study of the Coronary Sinus in the Indeterminate Form of Chagas Disease.

Introduction: We investigated the occurrence of coronary sinus abnormalities in the indeterminate form of Chagas disease (CD).

Methods: Differences between the maximum and minimum diameters of the coronary sinus (∆%) on echocardiography were evaluated in individuals with the indeterminate form of CD (n=14) and those without (n=16) CD. The association of the difference with abnormalities detected by echocardiography and myocardial scintigraphy was assessed.

Pupillometry in Chagas disease.

Purpose: We investigated parasympathetic innervation abnormalities of the iris sphincter and ciliary muscles in chronic Chagas disease by measuring pupillary diameter and intraocular pressure.

Methods: A group of 80 patients with Chagas disease was compared with 76 healthy individuals without chagasic infection. The following procedures were performed: pupillometry, hypersensitivity test to pilocarpine 0.

Ecological aspects of mosquitoes (Diptera: Culicidae) in the gallery forest of Brasília National Park, Brazil, with an emphasis on potential vectors of yellow fever.

Introduction: We analyzed the vertical and monthly distributions of culicid species in the gallery forest of Brasília National Park, with an emphasis on the potential vectors of yellow fever (YF).

Methods: Between September 2010 and August 2011, mosquitoes were captured on the ground and in the canopy of the forest for five consecutive days per month, from nine to 15 hours. The mosquitoes were examined to verify natural infection with flaviviruses by isolation in Aedes albopictus Skuse, 1864 cells followed by indirect immunofluorescence.

Occurrence of Triatoma costalimai (Hemiptera: Reduviidae) in different environments and climatic seasons: a field study in the Brazilian savanna.

The organism was isolated from an axillary lymph node and the bone marrow. Mediastinitis associated with disseminated M.

Occurrence of dolichocolon without megacolon in chronic Chagas disease patients.

Introduction: Since 1970, lengthening of the rectosigmoid has been suspected to be a solitary manifestation of Chagas colopathy.

Methods: To test this hypothesis, opaque enema was administered on 210 seropositive and 63 seronegative patients, and radiographs in the anteroposterior and posteroanterior positions were examined blind to the serological and clinical findings. The distal colon was measured using a flexible ruler along the central axis of the image from the anus to the iliac crest.

[Radiological study on megacolon cases in an endemic area for Chagas disease].

Introduction: A radiological study on the colon of patients from an endemic Chagas disease zone was conducted using the simplified opaque enema technique of Ximenes et al.

Insight into the salivary transcriptome and proteome of Dipetalogaster maxima.

Dipetalogaster maxima is a blood-sucking Hemiptera that inhabits sylvatic areas in Mexico. It usually takes its blood meal from lizards, but following human population growth, it invaded suburban areas, feeding also on humans and domestic animals. Hematophagous insect salivary glands produce potent pharmacologic compounds that counteract host hemostasis, including anticlotting, antiplatelet, and vasodilatory molecules.

[Assessment of an entomological surveillance system for Chagas disease with community participation in Mambaí and Buritinópolis, State of Goiás].

Entomological surveillance of Chagas disease in Mambaí and Buritinópolis, in the State of Goiás, Brazil, has been kept up through the local population's participation, consisting of reporting the presence of vectors inside their homes. A long time has elapsed since instituting these control measures and it has now been certified that vector transmission has been halted. Thus, this study sought to evaluate the population's knowledge and practices in this situation.
