Antiparasitic and anti-inflammatory activities of ß-lapachone-derived naphthoimidazoles in experimental acute Trypanosoma cruzi infection

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Chagas disease, which is caused by the protozoan Trypanosoma cruzi, is endemic to Latin America and mainly affects low-income populations. Chemotherapy is based on two nitrocompounds, but their reduced efficacy encourages the continuous search for alternative drugs. Our group has characterise...

Characterization of adverse reactions to benznidazole in patients with Chagas disease in the Federal District, Brazil

Abstract INTRODUCTION: Benznidazole is used for treating Chagas disease (CD). This cross-sectional study aimed to characterize the adverse drug reactions (ADRs) of benznidazole at a public hospital in Brazil's Federal District. METHODS: Medical records were analyzed and ADRs were categorized by type,...

Cardiac Evaluation in the Acute Phase of Chagas' Disease with Post-Treatment Evolution in Patients Attended in the State of Amazonas, Brazil

Arq. bras. cardiol; 112 (3), 2019
Abstract Background: In the past two decades, a new epidemiological profile of Chagas' disease (CD) has been registered in the Brazilian Amazon where oral transmission has been indicated as responsible for the increase of acute cases. In the Amazonas state, five outbreaks of acute CD have been registere...

Reactivation of Chagas disease in a heart transplant patient infected by sylvatic trypanosoma cruzi discrete typing unit I

Abstract Heart transplantation is an effective treatment for Chagas disease patients with severe cardiomyopathy. However, Trypanosoma cruzi reactivation is of great concern. The T. cruzi parasite is classified into six discrete typing units (DTUs identified as TcI-TcVI). It is unknown whether there is an...

In vitro genotoxicity of nitroimidazoles as a tool in the search of new trypanocidal agents

Mem. Inst. Oswaldo Cruz; 114 (), 2019
BACKGROUND Only benznidazole (Bnz) (1) and nifurtimox (Nfx) (2) are licensed for the treatment of Chagas disease although their safety and efficacy profile are far from ideal. Farmanguinhos from Fiocruz has developed seven nitroimidazole compounds (4-10) analogs of megazol (3). OBJECTIVES To evaluate ...

Chagas cardiomyopathy associated with serological cure after trypanocidal treatment during childhood

Abstract Chagas disease is a chronic parasitological disease, which could cause cardiac manifestations in approximately one-third of affected individuals. Benznidazole and nifurtimox are used to treat this parasitological infection caused by Trypanosoma cruzi. Conventionally, the criterion for cure is co...

New and repurposed drugs to treat multidrug- and extensively drug-resistant tuberculosis

J. bras. pneumol; 44 (2), 2018
ABSTRACT Multidrug-resistant and extensively drug-resistant tuberculosis (MDR-TB and XDR-TB, respectively) continue to represent a challenge for clinicians and public health authorities. Unfortunately, although there have been encouraging reports of higher success rates, the overall rate of favorable out...

Therapeutic drug monitoring of benznidazole and nifurtimox: a systematic review and quality assessment of published clinical practice guidelines

Abstract The pharmacological management of adults with chronic-phase Chagas disease is challenging despite it being the recent focus of extensive research. One of the challenges in the current clinical practice guidelines (CPGs) landscape is the existence of non-evidence-based recommendations for the use...
