Predictive Factors of Severe Behçet's disease: A Longitudinal, Prospective Cohort Followed Between 1981-2020.

INTRODUCTION: Behçet's disease (BD) is a systemic vasculitis of unknown cause. The spectrum of the disease ranges from mucocutaneous manifestations to other organ diseases with relevant morbidity. Associations between disease severity and male sex, earlier age at onset, and the presence of erythema nodosum have been described. OBJECTIVES: To evaluate clinical factors associated with manifestations of severe disease in a single-center cohort. METHODS: A longitudinal, prospective, unicentric cohort study with patients followed in a specialized outpatient clinic between 1981 and 2020. Severe BD was defined as a Krause total clinical severity score >4 points. RESULTS: We included 243 patients, of whom 31% were male, with an average follow-up time of 14.6 years. Regarding organ manifestations, all patients had mucous manifestations (N=243, 100%), 133 (55%) skin, 104 (43%) joint, 71 (29%) ocular, 48 (20%) vascular, 47 (19%) neurological, 22 (9%) gastrointestinal and 1 (0.4%) cardiac involvement by BD. One hundred fifty-six (64%) patients were classified as having severe BD. Severe BD was more frequent in men (OR=2.004, p=0.024), increasing with age (OR=1.021 per year, p=0.037), in the presence of skin manifestations (OR=4.711, p<0.001), specifically erythema nodosum (OR=8.381, p<0.001), and pseudofolliculitis (OR=2.910, p<0.001). In the multivariate model, variables independently associated with severe BD were male gender (Adjusted OR=1.961, p=0.047), erythema nodosum (Adjusted OR=8.561, p<0.001) and pseudofolliculitis (Adjusted OR=2.372, p=0.007). DISCUSSION: Male gender, erythema nodosum, and pseudofolliculitis were independently associated with severe BD forms and therefore should serve as warning signs to the clinician.

Introducción: La enfermedad de Behçet (EB) es una vasculitis sistémica de causa desconocida. El espectro de la enfermedad abarca desde manifestaciones mucocutáneas hasta otras enfermedades de órganos con morbilidad relevante. Se han descrito asociaciones entre la gravedad de la enfermedad y el sexo masculino, la edad de inicio más temprana y la presencia de eritema nudoso. Objetivos: Evaluar los factores clínicos asociados con las manifestaciones de enfermedad grave en una cohorte de un solo centro. Métodos: Estudio de cohorte longitudinal, prospectivo y unicéntrico con pacientes seguidos en una clínica ambulatoria especializada entre 1981 y 2020. La EB grave se definió como una puntuación Krause total clinical severity score≥4 puntos. Resultados: Se incluyeron 243 pacientes, de los cuales el 31% eran varones, con un tiempo de seguimiento medio de 14,6 años. En cuanto a las manifestaciones orgánicas, todos los pacientes presentaron manifestaciones mucosas (n=243, 100%), 133 (55%) piel, 104 (43%) articular, 71 (29%) ocular, 48 (20%) afectación vascular, 47 (19%) neurológica, 22 (9%) gastrointestinal y 1 (0,4%) cardiaca por EB; 156 (64%) pacientes fueron clasificados como con EB grave. La EB severa fue más frecuente en hombres (OR=2,004, p=0,024), aumentando con la edad (OR=1,021 por año, p=0,037), en presencia de manifestaciones cutáneas (OR=4,711, p<0,001), específicamente eritema nodosum (OR=8,381, p<0,001) y pseudofoliculitis (OR=2,910, p<0,001). En el modelo multivariado, las variables asociadas de forma independiente con el EB grave fueron el sexo masculino (OR ajustado=1,961, p=0,047), eritema nudoso (OR ajustado=8,561, p<0,001) y pseudofoliculitis (OR ajustado=2,372, p=0,007). Discusión: El sexo masculino, el eritema nudoso y la pseudofoliculitis se asociaron de forma independiente con formas graves de DB y, por lo tanto, deberían servir como signos de advertencia para el médico.(AU)
