Características clínicas, tratamiento y complicaciones oculares de uveítis anterior asociada y no asociada a HLA-B27 / Clinical characteristics, treatment and ocular complications of HLA-B27-related anterior uveitis and HLA-B27-non related anterior uveitis

Introducción. La uveítis anterior es la forma más frecuente de inflamación intraocular. Las formas asociadas al antígeno HLA-B27 suponen entre un 18 y un 32% de los casos de uveítis anterior. Objetivos. Describir las características clínicas, la necesidad de tratamiento sistémico y la frecuencia y el tipo de complicaciones oculares de una cohorte de pacientes con uveítis anterior asociada a HLA-B27 y de una cohorte de pacientes con uveítis anterior no asociada a HLA-B27. Establecer si existen diferencias entre ambas cohortes. Material y métodos. Se realiza un estudio de cohortes retrospectivo descriptivo con componentes analíticos incluyendo a pacientes con uveítis anterior endógena no infecciosa asociada y no asociada a HLA-B27. Resultados. Se incluye un total de 162 pacientes, 58 con uveítis anterior asociada a HLAB27 (cohorte HLA-B27+) y 104 con uveítis anterior no asociada a HLA-B27 (cohorte HLA-B27-). No se aprecian diferencias estadísticamente significativas en las características clínicas de ambas cohortes a excepción de una mayor tendencia a la recurrencia en la cohorte HLA-B27+ y una mayor tendencia a la cronicidad en la cohorte HLA-B27-. Tampoco se aprecian diferencias en cuanto al uso de tratamiento sistémico ni al desarrollo de complicaciones oculares de forma global. Conclusiones. A diferencia de lo descrito con anterioridad, en este trabajo no encontramos un mayor predominio masculino en la cohorte de uveítis asociada a HLA-B27. Tampoco se aprecian diferencias en edad media, lateralidad, presencia de complicaciones ni frecuencia de uso de corticoides sistémicos (AU)

Introduction. Anterior uveitis is the most common type of intraocular inflammation. Those associated to HLA-B27 represent 18 to 32% of all anterior uveitis cases. Objectives. To describe clinical characteristics, systemic treatment need, and frequency and type of ocular complications in a cohort of patients diagnosed with HLAB27-related anterior uveitis and in a cohort of patients diagnosed with HLA-B27 non-related anterior uveitis. To establish if statistically significant differences between both cohorts exist. Material and methods. We performed a retrospective cohort study including patients with non infectious anterior uveitis related and not related to the antigen HLA-B27. Results. 162 patients were included, 58 diagnosed with HLA-B27-related anterior uveitis (cohort HLA-B27+1) and 104 diagnosed with HLA-B27- non related anterior uveitis (cohort HLA-B27-). No statistically significant differences were found regarding clinical characteristics between both cohorts with the exception of a higher frequency of recurrences in cohort HLA-B27+ and a higher frequency of chronic uveitis in cohort HLA-B27-. No differences were found regarding systemic treatment use nor development of ocular complications. Discussion. In contrast to previous studies, we neither found higher male gender predominance in the cohort of patients with HLA-B27-related anterior uveitis, Nor did we find differences regarding average age, laterality, development of complications nor use of systemic corticosteroids (AU)

INTRODUCTION: Anterior uveitis is the most common type of intraocular inflammation. Those associated to HLA-B27 represent 18 to 32% of all anterior uveitis cases. OBJECTIVES: To describe clinical characteristics, systemic treatment need, and frequency and type of ocular complications in a cohort of patients diagnosed with HLAB27-related anterior uveitis and in a cohort of patients diagnosed with HLA-B27 non-related anterior uveitis. To establish if statistically significant differences between both cohorts exist. MATERIAL AND METHODS: We performed a retrospective cohort study including patients with non infectious anterior uveitis related and not related to the antigen HLA-B27. RESULTS: 162 patients were included, 58 diagnosed with HLA-B27-related anterior uveitis (cohort HLA-B27+1) and 104 diagnosed with HLA-B27- non related anterior uveitis (cohort HLA-B27-). No statistically significant differences were found regarding clinical characteristics between both cohorts with the exception of a higher frequency of recurrences in cohort HLA-B27+ and a higher frequency of chronic uveitis in cohort HLA-B27-.
