Anticuerpo anticitrulina y manifestaciones extra articulares en artritis reumatoidea / Anticitrulin antibody and the extra-articular manifestations in rheumatoid arthritis

Los pacientes con artritis reumatidea (AR) pueden desarrollar manifestaciones extra articulares (MExA), relacionadas a su morbi-mortalidad. Los anticuerpos anti-péptidos citrulinados cíclicos (ACCP) son específicos para la AR y estan relacionados con el daño articular; y podrían tener rol patogénico en las MExA. Nuestro objetivo fue determinar la relación entre los anticuerpos ACCP y MExA en pacientes con AR. Se incluyeron 74 pacientes con diagnóstico de AR (ACR 1987) mayores de 18 años, de más de 6 meses de evolución, con MExA, y un control apareado por sexo y edad sin MExA por cada paciente. Las variables demográficas, clínicas y de laboratorio se compararon con test t, chi cuadrado o Mann-Whitney. Se realizó análisis multivariado; p ≤ 0.05. Los pacientes con MExA presentaron mayor título de anticuerpo ACCP (116 vs. 34, p < 0.01) y de factor reumatoideo (FR) (108 vs. 34.5, p < 0.01). En el análisis multivariado hubo asociación entre la presencia de MExA y tabaquismo activo (p = 0.02, OR: 3.78, IC 95%: 1.17-12.2), FR positivo (p = 0.04, OR: 3.23, IC95%: 1.04-11.8) y anticuerpo ACCP positivo (p = 0.04, OR: 3.23, IC 95%: 1.04-10). Presentaron mayor título de anticuerpo ACCP que los controles los pacientes con xerostomía (109 vs. 34, p = 0.04), xeroftalmia (150 vs. 34, p < 0.01), nódulos sub-cutáneos (NSC) (141 vs. 34, p < 0.01) y fibrosis pulmonar (158 vs. 34, p = 0.04). En conclusión, el anticuerpo ACCP positivo, el FR positivo y el tabaquismo activo fueron factores de riesgo independientes para el desarrollo de MExA.

A large proportion of rheumatoid arthritis (RA) patients develop extra-articular manifestations (EAM), which are associated with morbidity and early mortality. Anti cyclic citrullinated peptide (ACCP) antibody has proven to be highly specific for the diagnosis of RA, associated with severe joint damage and may have some role in the pathogenesis of EAM. The aim of this study was to determine the relationship between ACCP antibody and the presence of EAM in RA patients. Seventy four RA patients (ACR 1987) with EAM, > 18 years, more than 6 months duration were included, and an EAM free control, matched by sex and age, for each patient. Demographic, clinical and laboratory variables were compared using t-test, chi-square or Mann-Whitney test. Multivariate analysis was performed: p ≤ 0.05. Patients with EAM presented a greater value of ACCP antibody (116 vs. 34, p < 0.01) and rheumatoid factor (108 vs. 34.5, p < 0.01). Independent association with current smoking habit (p = 0.02, OR = 3.78, 95%: 1.17-12.2), RF positive (p = 0.04, OR 3.23, CI 95%: 1.04 to 11.8) and ACCP antibody positive (p = 0.04, OR 3.23, 95% CI: 1.04-10) was found. The patients with xerostomia (109 vs. 34, p = 0.04), xerophthalmia (150 vs. 34, p < 0.01), subcutaneous nodules (141 vs. 34, p < 0.01) and pulmonary fibrosis (158 vs. 34, p = 0.04) had a higher degree of the ACCP antibody, than controls. In conclusion, ACCP antibody positive, RF positive and smoking were independent risk factors for the development of MEXA.

Vasculitis con necrosis digital asociada con interferón beta / Vasculitis with digital necrosis associated with beta interferon

El interferon (IFN) es una citoquina producida por distintas poblaciones de células y, a partir de su estructura, se han desarrollado varias drogas biológicas utilizadas en un amplio espectro de enfermedades. Se han descripto lesiones cutáneas y casos de síndrome de Raynaud severo con gangena digital co IFN alfa y beta. En este reporte presentamos una paciente con necrosis digital asociada a la administración de IFN beta

Interferon (IFN) is a cytokine produced by different immune competentcells and, based on its structure, several IFN biologic drugs and are now used as treatment for a wide spectrum of diseases. There are reports of cutaneous side effects and cases of severe Raynaud ́s syndrome with digital gangrene especially with both alpha and beta IFN. We report a patient who developed digital necrosis associated with beta Interferon.
