IgE antibodies from schistosomiasis patients to recognize epitopes in potato apyrase.

Rev Soc Bras Med Trop 2019 Mar 28;52:e20180139. Epub 2019 Mar 28.

Instituto de Ciências Biológicas, Universidade Federal de Juiz de Fora, Juiz de Fora, MG, Brasil.

Introduction: High percentages of structural identity and cross-immunoreactivity have been reported between potato apyrase and Schistosoma mansoni ATP diphosphohydrolase (SmATPDases) isoforms, showing the existence of particular epitopes shared between these proteins.

Methods: Potato apyrase was employed using ELISA, western blot, and mouse immunization methods to verify IgE reactivity.

Results: Most of the schistosomiasis patient's (75%) serum was seropositive for potato apyrase and this protein was recognized using western blotting, suggesting that parasite and plant proteins share IgE-binding epitopes. Read More

Faculdade de Medicina da Universidade Federal de Minas Gerais, Belo Horizonte, MG, Brasil.

Rheumatic heart disease (RHD) remains a major cause of preventable death and disability in children and young adults. Despite significant advances in medical technology and increased understanding of disease mechanisms, RHD continues to be a serious public health problem throughout the world, especially in low- and middle-income countries. Echocardiographic screening has played a key role in improving the accuracy of diagnosing RHD and has highlighted the disease burden. Read More

Current vector control challenges in the fight against malaria in Brazil.

Rev Soc Bras Med Trop 2019 Mar 7;52:e20180542. Epub 2019 Mar 7.

Fundação de Medicina Tropical Dr. Heitor Vieira Dourado, Manaus, AM, Brasil.

In Brazil, malaria is an important public health problem first reported in 1560. Historically, fluctuations in malaria cases in Brazil are attributed to waves of economic development; construction of railroads, highways, and hydroelectric dams; and population displacement and land occupation policies. Vector control measures have been widely used with an important role in reducing malaria cases. Read More

ERG11 gene polymorphisms and susceptibility to fluconazole in Candida isolates from diabetic and kidney transplant patients.

Rev Soc Bras Med Trop 2019 Mar 7;52:e20180473. Epub 2019 Mar 7.

Departamento de Patologia Básica, Universidade Federal do Paraná, Curitiba, PR, Brasil.

Introduction: Candidiasis is the most frequent opportunistic mycosis in humans and can cause mortality, particularly in immunodeficient patients. One major concern is the increasing number of infections caused by drug-resistant Candidas trains, as these cannot be efficiently treated with standard therapeutics. The most common mechanism of fluconazole resistance in Candida is mutation of ERG11, a gene involved in the biosynthesis of ergosterol, a compound essential for cell integrity and membrane function.
