[Epidemiological, clinical, and biochemical characteristics of patients in the LUPUS-IMMex cohort]. / Características epidemiológicas, clínicas y bioquímicas de los pacientes en la cohorte LUPUS-IMMex.

Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect multiple organs and body systems. Objective: To describe the sociodemographic, clinical, and biochemical characteristics of the Lupus-IMMS-Mexico (LUPUS-IMMex) patient cohort from a tertiary-level center. Material and methods: Observational descriptive study of 160 patients with diagnosis of SLE belonging to the aforementioned cohort. Various variables were analyzed at the time of diagnosis. For quantitative variables, normality tests were applied, followed by measures of central tendency and dispersion according to their distribution. For categorical variables, frequencies and percentages were calculated. Results: 81.87% of the patients were female, with a median age at diagnosis of 28 years. 18.12% had a family history of SLE, and concurrently with SLE, 32.50% had hypertension, and 11.25% had antiphospholipid syndrome. The most common clinical manifestation was joint involvement (68.12%), renal (49.37%) and hematological (43.75%) manifestations. Conclusions: SLE affects millions globally. Lack of awareness leads to delayed diagnoses, suboptimal management, and diminished quality of life. After analyzing 160 patients with SLE, their clinical, socioeconomic, and therapeutic characteristics are largely like other cohorts, with differences attributable to ethnic and geographical influences. Informing patients about SLE and providing reliable resources are essential for self-care. Awareness promotes research, therapies, and enhances medical care and the lives of patients globally.

Introducción: el lupus eritematoso sistémico (LES) es una enfermedad autoinmunitaria crónica que puede afectar a múltiples órganos y sistemas del cuerpo. Objetivo: describir las características sociodemográficas, clínicas y bioquímicas de la cohorte de pacientes Lupus-IMMS-México (LUPUS-IMMex) de un hospital de tercer nivel. Material y métodos: estudio descriptivo observacional de 160 pacientes con diagnóstico de LES de la cohorte mencionada. Se analizaron diversas variables al momento del diagnóstico. Para variables cuantitativas se aplicaron pruebas de normalidad y posteriormente medidas de tendencia central y dispersión de acuerdo con su distribución. Para variables categóricas se calcularon frecuencias y porcentajes. Resultados: 81.87% de los pacientes fueron del sexo femenino, con mediana de edad al diagnóstico de 28 años. El 18.12% tenían antecedentes familiares de LES y concomitante al LES, hipertensión (32.50%) y síndromes antifosfolípidos (11.25%). Las afecciones clínicas más frecuentes fueron la articular (68.12%), la renal (49.37%) y la hematológica (43.75%). Conclusiones: el LES afecta a millones de personas globalmente. La falta de conciencia lleva a diagnósticos tardíos, manejo deficiente y baja calidad de vida. Tras analizar 160 pacientes con LES, sus características clínicas, socioeconómicas y terapéuticas son mayormente similares a otras cohortes, con diferencias atribuibles a influencias étnicas y geográficas. Informar a los pacientes sobre el LES y brindar recursos confiables es esencial para el autocuidado. La sensibilización fomenta la investigación, las terapias y mejora la atención médica y la vida de pacientes a nivel global.

Uveitis in adult patients with rheumatic inflammatory autoimmune diseases at a tertiary-care hospital in Mexico City.

OBJECTIVE: Our aim is to describe the frequency of uveitis associated with rheumatic inflammatory autoimmune diseases (RIAD) in adult patients admitted to the Rheumatology Department at a tertiary-care hospital in Mexico City. We also describe the clinical features, seasonal distribution, treatment, and ocular complications associated with this disease. METHODS: We reviewed 1332 charts of patients with RIAD and selected those that had a diagnosis of uveitis. We obtained the following data: age, sex, type of uveitis and relationship with diagnosis of RIAD, recurrences, seasonal distribution, treatment, and residual visual deficit. RESULTS: We found 57 (4.27%) cases of uveitis in 1332 charts, including 38 men and 19 women (M:F ratio 2:1), aged 47 ± 16 years. Nongranulomatous acute anterior uveitis (NGAAU) comprised 90.52% of cases (52/57). In 64.91% of cases (37/57), uveitis preceded the diagnosis of RIAD by 12 ± 9 years, more frequently in winter (35.96%; p = NS). Uveitis was found in 40/93 patients with ankylosing spondylitis (AS), in 7/11 patients with relapsing polychondritis (RP), in 8/16 patients with Behçet's disease, in 1/16 patients with polyarteritis nodosa, and in 1/590 patients with rheumatoid arthritis (RA). Ninety-six percent of the patients were treated with steroids. Upon a mean followup of 60 days (range 7-4745 days), reduction of visual acuity (≤ 20/200) was associated with recurrence of uveitis in 3/7 cases with AS, in 4/8 cases with Behçet's disease, in 3/7 with RP, and in 1 case of uveitis and seronegative RA. CONCLUSION: NGAAU frequently precedes RIAD and is found predominately in men, with a tendency to occur in winter.
