Very early and early systemic sclerosis in the Spanish scleroderma Registry (RESCLE) cohort.

Objectives: According to the existence of subclinical organ involvement pre-scleroderma should be divided into two subsets: very early and early disease. Pre-scleroderma patients included in the Spanish Scleroderma Registry (RESCLE) Cohort were reclassified into subsets. Differences were evaluated and the risk of progression to definite systemic sclerosis was estimated.

Latent orbital pseudotumor secondary to systemic lupus erythematosus.

Orbital inflammatory pseudotumor is a rare complication of systemic lupus erythematosus. It may present a challenge for differential diagnosis, especially in the context of treatment with hydroxychloroquine, although dosage and duration of the treatment may guide us. Although high antibody titers can be found, this is not specific.

Common and specific associations of anti-SSA/Ro60 and anti-Ro52/TRIM21 antibodies in systemic lupus erythematosus.

Little information exists about the association of anti-SSA/Ro60 and anti-Ro52/TRIM21 with systemic lupus erytematosus (SLE) features. In this work, we analysed the associations of both anti-Ro reactivities with clinical and immunological manifestations in 141 SLE patients. Photosensitivity and xerophtalmia/xerostomia were found to be positively associated with both anti-SSA/Ro60 (P = 0.

Vascular calcifications, vertebral fractures and mortality in haemodialysis patients.

Background: Vascular calcifications and the bone fractures caused by abnormal bone fragility, also called osteoporotic fractures, are frequent complications associated with chronic kidney diseases (CKD). The aim of this study was to investigate the association between vascular calcifications, osteoporotic bone fractures and survival in haemodialysis (HD) patients.

Methods: A total of 193 HD patients were followed up to 2 years.

Isolated ophthalmologic relapse in a case of suspected microscopic polyangiitis.

Purpose: To report a case of suspected microscopic polyangiitis (MPA) with isolated retinal vasculitis not described previously.

Methods: Case report.

Results: A 50-year-old man was admitted to the hospital because of retinal vasculitis.

Vitamin D status and secondary hyperparathyroidism: the importance of 25-hydroxyvitamin D cut-off levels.

Background: Serum 25-hydroxyvitamin D is the best indicator of vitamin D status. However, some controversy remains regarding "normal" and "abnormal" values. This study's aim was to assess vitamin D status and prevalence of secondary hyperparathyroidism.
