Abstract
Objective

To describe the demographic and clinical features, as well as the frequency of the HLA-B*51 allele in Behçet disease (BD) patients in Latin American countries.

Methods

A systematic literature review of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines was conducted without performing a meta-analysis. We included observational studies (cross-sectional or cohort) of BD patients fulfilling the International Study Group for BD classification criteria and reported the demographic, clinical, and laboratory features of the disease in adult patients.

Results

Twelve studies were included in the SLR. Information from 532 patients across 5 Latin American countries was included for the analysis. Mean age at disease diagnosis was 33 years, 58.3% were female and 41.7% male; most patients were non-Caucasian. The most common clinical manifestations were recurrent oral ulcers and genital ulcers, followed by skin, eye, joint, neurological, gastrointestinal, vascular, and cardiac involvement. The prevalence of BD was described in 2 studies, 1 conducted in Brazil that reported a prevalence of .3/100,000 inhabitants, and another in Colombia with a prevalence of 1.1/100,000 inhabitants. The frequency of HLA-B*51 allele in BD patients was 38%, 30.1%, and 9% in Argentina, Brazil, and Mexico, respectively.

Conclusions

The prevalence of BD in the Latin American countries seems to be low, as well as the frequency of HLA-B*51 allele. However, the strength of association between HLA-B*51 and BD remains high in our population. The key clinical features of BD are like those reported in countries/regions where BD is endemic.

Resumen
Objetivo

Describir las características demográficas, clínicas y la frecuencia del alelo HLA-B*51 en pacientes con enfermedad de Behçet (EB) en países de América Latina.

Métodos

Se llevó a cabo una revisión sistemática de la literatura (RSL) según la guía PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) sin realizar un metaanálisis final. Se incluyeron estudios observacionales (transversales o de cohortes) de pacientes con EB que cumplieron con los criterios de clasificación del Grupo Internacional de Estudio de la EB e informaron las características demográficas, clínicas y de laboratorio en pacientes adultos con EB.

Resultados

Doce estudios fueron incluidos para la RSL. La información de 532 pacientes provenientes de 5 países de América Latina se incluyó para el análisis. La edad media al diagnóstico fue de 33 años, el 58,3% fueron mujeres y el 41,7% hombres; la mayoría de los pacientes fueron no caucásicos. Las manifestaciones clínicas más comunes fueron las úlceras orales y genitales recurrentes, seguidas del compromiso cutáneo, ocular, articular, neurológico, gastrointestinal, vascular y cardíaco. La prevalencia de la EB fue descrita en 2 estudios, uno realizado en Brasil que reportó una prevalencia de 0,3/100.000 habitantes, y otro en Colombia con una prevalencia de 1,1/100.000 habitantes. La frecuencia del HLA-B*51 en pacientes con EB fue del 38%, 30,1% y 9% en Argentina, Brasil y México, respectivamente.

Conclusiones

La prevalencia de la EB en los países latinoamericanos parece ser baja, así como la frecuencia del alelo HLA-B*51. Sin embargo, la fuerza de asociación entre el HLA-B*51 y la EB sigue siendo alta en nuestra población. Las características clínicas claves de la EB son similares a las reportadas en países/regiones donde es endémica.
