ABSTRACT
Background: NADPH-oxidase and myeloperoxidase (MPO) play an important role on defense against pathogenic microorganisms. Defects on these mechanisms have been described in association with recurrent infections due to such as Staphylococcus aureus and Candida albicans. We describe a patient with partial disturbance of intracellular microorganism destruction clinically manifested by recurrent fungal infection. Case report and results: A 58-year-old male rural farmer has suffered with superficial mycosis affecting hands, nails and right ankle persisting for 20 years. He was treated with several antifungal drugs with no improvement. Mycological scraping isolated Trichophyton rubrum. Immunological evaluation showed impaired T cell proliferation to Candidin and impaired neutrophil burst oxidative after specific stimulation with Candida albicans. The patient's DNA was extracted from peripheral blood leukocytes for whole exome sequencing (WES) analysis. Two heterozygous variants of undetermined significance were screened accordingly: (1) MPO A332V (c.995G>A; rs28730837); and (2) NCF1 G83R (c.247G>A; rs139225348). Conclusions: Functional leukocyte evaluation with heterozygous variants in MPO and NCF1 suggest that these defects were associated with the susceptibility to dermatophytosis in our patient. We have developed a fast, effective and safe trial for screening individuals with yeast infections.
ABSTRACT
Hereditary angioedema is an autosomal dominant disease characterized by recurrent angioedema attacks with the involvement of multiple organs. The disease is unknown to many health professionals and is therefore underdiagnosed. Patients who are not adequately diagnosed and treated have an estimated mortality rate ranging from 25% to 40% due to asphyxiation by laryngeal angioedema. Intestinal angioedema is another important and incapacitating presentation that may be the main or only manifestation during an attack. In this article, a group of experts from the "Associação Brasileira de Alergia e Imunologia (ASBAI)" and the "Grupo de Estudos Brasileiro em Angioedema Hereditário (GEBRAEH)" has updated the Brazilian guidelines for the diagnosis and treatment of hereditary angioedema.

O angioedema hereditário é uma doença autossômica dominante caracterizada por crises de edema com o envolvimento de múltiplos órgãos. A doença é desconhecida por muitos profissionais da área da saúde e, portanto, subdiagnosticada. Os pacientes que não são diagnosticados e tratados adequadamente têm uma mortalidade estimada de 25% a 40%, devido ao angioedema da laringe, resultando em asfixia. O angioedema de alças intestinais é outra manifestação importante e incapacitante, que pode ser a principal ou a única durante uma crise da doença. Neste cenário, um grupo de especialistas da Associação Brasileira de Alergia e Imunologia (ASBAI) e do Grupo de Estudos Brasileiro em Angioedema Hereditário (GEBRAEH) atualizou as diretrizes para o diagnóstico e terapia do angioedema hereditário.
