The Use of Quinacrine in Nitroimidazole-resistant Giardia Duodenalis: An Old Drug for an Emerging Problem.

Background: There is little evidence regarding the management of refractory giardiasis after treatment with nitroimidazoles. This study estimates the proportion of persistent giardiasis in 3 hospitals in Barcelona, describes associated risk factors and genotype, and evaluates the efficacy rate of quinacrine in those with persistent giardiasis.

Methods: A clinical, prospective, observational study was conducted in patients with giardiasis treated with nitroimidazoles.

Controlling congenital and paediatric chagas disease through a community health approach with active surveillance and promotion of paediatric awareness.

Background: Chagas disease (CD) is endemic in countries of continental Latin America. Congenital transmission is a major concern worldwide. In 2010, the Public Health Agency of Catalonia (ASPCAT) launched a screening protocol for Trypanosoma cruzi infection in pregnant women and their newborns.

Randomized trial of posaconazole and benznidazole for chronic Chagas' disease.

Background: Current therapeutic options for Chagas' disease are limited to benznidazole and nifurtimox, which have been associated with low cure rates in the chronic stage of the disease and which have considerable toxicity. Posaconazole has shown trypanocidal activity in murine models.

Methods: We performed a prospective, randomized clinical trial to assess the efficacy and safety of posaconazole as compared with the efficacy and safety of benznidazole in adults with chronic Trypanosoma cruzi infection.

Trypanosoma cruzi infection in a non-endemic country: epidemiological and clinical profile.

Chagas disease has been increasingly diagnosed in non-endemic countries. This is a prospective observational study performed at the Tropical Medicine Units of the International Health Program of the Catalan Health Institute, Barcelona (PROgrama de Salud Internacional del Instituto Catalán de la Salud, PROSICS Barcelona, Spain), that includes all patients with Chagas disease who attended from June 2007 to May 2012. Clinical and epidemiological data were collected.

Epidemiology of imported malaria among children and young adults in Barcelona (1990-2008).

Background: Increasing international travel and migration is producing changes in trends in infectious diseases, especially in children from many European cities. The objective of this study was to describe the epidemiology and determine the trends of imported malaria in patients under 20 years old in the city of Barcelona, Spain, during an 18-year period.

Methods: The study included malaria cases that were laboratory confirmed and reported to the malaria register at the Public Health Agency of Barcelona from 1990 to 2008, residing in Barcelona and less than 20 years old.
