Relevance of gastrointestinal manifestations in a large Spanish cohort of patients with systemic lupus erythematosus: what do we know?

OBJECTIVE: SLE can affect any part of the gastrointestinal (GI) tract. GI symptoms are reported to occur in >50% of SLE patients. To describe the GI manifestations of SLE in the RELESSER (Registry of SLE Patients of the Spanish Society of Rheumatology) cohort and to determine whether these are associated with a more severe disease, damage accrual and a worse prognosis. METHODS: We conducted a nationwide, retrospective, multicentre, cross-sectional cohort study of 3658 SLE patients who fulfil ≥4 ACR-97 criteria. Data on demographics, disease characteristics, activity (SLEDAI-2K or BILAG), damage (SLICC/ACR/DI) and therapies were collected. Demographic and clinical characteristics were compared between lupus patients with and without GI damage to establish whether GI damage is associated with a more severe disease. RESULTS: From 3654 lupus patients, 3.7% developed GI damage. Patients in this group (group 1) were older, they had longer disease duration, and were more likely to have vasculitis, renal disease and serositis than patients without GI damage (group 2). Hospitalizations and mortality were significantly higher in group 1. Patients in group 1 had higher modified SDI (SLICC Damage Index). The presence of oral ulcers reduced the risk of developing damage in 33% of patients. CONCLUSION: Having GI damage is associated with a worse prognosis. Patients on a high dose of glucocorticoids are at higher risk of developing GI damage which reinforces the strategy of minimizing glucocorticoids. Oral ulcers appear to decrease the risk of GI damage.

Cardiovascular mortality and cardiovascular event rates in patients with inflammatory rheumatic diseases in the CARdiovascular in rheuMAtology (CARMA) prospective study-results at 5 years of follow-up.

OBJECTIVES: To determine cardiovascular (CV) mortality and incidence of the first CV event (CVE) in patients with chronic inflammatory rheumatic diseases (CIRD) after 5 years of follow-up. METHODS: This is an analysis of the CARdiovascular in rheMAatology (CARMA) study after 5 years of follow-up. It includes patients with RA (n = 775), AS (n = 738) and PsA (n = 721), and individuals without CIRD (n = 677) attending outpatient rheumatology clinics from 67 public hospitals in Spain. Descriptive analyses were performed for the CV mortality at 5 years. The Systematic COronary Risk Evaluation (SCORE) function at 5 years was calculated to determine the expected risk of CV mortality. Poisson models were used to estimate the incidence rates of the first CVE. Hazard ratios of the risk factors involved in the development of the first CVE were evaluated using the Weibull proportional hazard model. RESULTS: Overall, 2382 subjects completed the follow-up visit at 5 years. Fifteen patients died due to CVE. CV deaths observed in the CIRD cohort were lower than that predicted by SCORE risk charts. The highest incidence rate of CVE [7.39 cases per 1000 person-years (95% CI 4.63, 11.18)] was found in PsA patients. However, after adjusting for age, sex and CV risk factors, AS was the inflammatory disease more commonly associated with CVE at 5 years [hazard ratio 4.60 (P =0.02)], compared with those without CIRD. CONCLUSIONS: Cardiovascular mortality in patients with CIRD at 5 years of follow-up is lower than estimated. Patients with AS have a higher risk of developing a first CVE after 5 years of follow-up.

Safety and retention rate of off-label uses of TNF antagonists in rheumatic conditions: data from the Spanish registry BIOBADASER 2.0.

OBJECTIVE: To compare the safety and retention rate of TNF antagonists used in approved indications (AIs) and non-AIs. METHODS: Analysis of the Spanish registry BIOBADASER 2.0 (February 2000 to October 2009). Patients were classified into AIs and off-label uses (OUs), according to the European Medicines Agency approval. Retention rates, incidence rates (IRs) and IR ratios (IRRs) of adverse events (AEs) with 95% CI were compared between uses, by log-rank test, cause-specific Cox regression models and generalized linear models with Poisson's distribution. RESULTS: First treatment with TNF antagonist was available in 5150 patients, of whom 4594 (89%) were AIs (2854 RA, 882 AS and 858 PsA) and 556 (11%) were OUs [437 chronic arthropathies in the spectrum of SpAs (CA) and 119 chronic immune-mediated diseases (CIDs)]. The IR of AE was largest in CID (649 events per 1000 patient-years) and lowest in PsA (250 events per 1000 patient-years). The occurrence of AEs was significantly associated with OU [IRR of CA vs RA 1.33 (95% CI 1.19, 1.49); IRR of CID vs RA 1.94 (95% CI 1.62, 2.31). The largest hazard ratio for discontinuation was for CID vs RA (1.33; 95% CI 1.02, 1.71) and especially vs AS (2.18; 95% CI 1.63, 2.90). CONCLUSIONS: OUs of TNF antagonists need a very close ascertainment of risk/benefit. The safety and retention pattern for CID is similar to that for RA and the pattern for CA resembles that of AS. This study shows an additional value of a national registry.
