  ObjectiveTo assess the prevalence of anti–carbamylated protein (anti‐CarP) antibodies in a French cohort of patients with early arthritis and to investigate their association with clinical features, final diagnosis, prognosis, and comorbidities.MethodsThe presence of anti‐CarP antibodies among patients with early arthritis in the French Etude et Suivi des Polyarthrites Indifférenciées Récentes (ESPOIR) cohort (n = 720) was determined using enzyme‐linked immunosorbent assay. We investigated the prevalence of anti‐CarP antibodies in different patient subgroups stratified according to anti–citrullinated protein antibody (ACPA) and/or rheumatoid factor (RF) status. Diagnostic and prognostic values of the test were evaluated in this population.ResultsAnti‐CarP antibodies were present in approximately one‐third of the patients (32.6%) and in 23.6% of the patients who were seronegative for both RF and ACPA. Anti‐CarP positivity was associated with a more active disease status at baseline and over time. Anti‐CarP–positive patients had a significantly higher Disease Activity Score in 28 joints using the erythrocyte sedimentation rate at month 36 than anti‐CarP–negative patients (3.1 ± 0.11 versus 2.8 ± 0.06; P = 0.03). Anti‐CarP–positive early arthritis was associated with a higher risk of developing erosions after 96 months of follow‐up (55.6% of anti‐CarP–positive patients versus 37.3% of anti‐CarP–negative patients) (odds ratio 2.1 [95% CI 1.2–3.6]; P = 0.009). This association was particularly true when anti‐CarP was associated with ACPA positivity. Moreover, ACPA positivity alone in early arthritis was not associated with a higher risk of erosive evolution.ConclusionOur findings indicate that anti‐CarP antibodies are present in one‐third of patients with early arthritis and in one‐fourth of the RF‐negative and ACPA‐negative patients. They are particularly associated with a more severe radiographic outcome. Anti‐CarP antibody positivity may help to accurately identify those at risk of erosive evolution in an early arthritis population.

  Abstract Objectives The primary objective of this study was to assess the stressful life events preceding the onset of symptoms in RA. The secondary objectives were to assess how early RA patients perceive stress and cope with stressors. Methods A case–control study was performed, comparing patients recently diagnosed with RA to age- and gender-matched control subjects recently hospitalized for an unplanned surgical procedure not known to be influenced by stress. The Social Readjustment Rating Scale assessed the cumulative stress induced by stressful life events in the year preceding the onset of symptoms. Coping strategies, stress and anxiety symptoms were evaluated using validated psychological scales. Results Seventy-six subjects were included in each group. The mean Social Readjustment Rating Scale score was twice as high in cases compared with controls [respectively, 167.0 (172.5) vs 83.3 (124.4), P < 0.001]. The association between cumulative stress and RA was statistically significant only in women, with a dose-dependent association between stress and RA. While female patients with RA attributed more often the onset of symptoms to a life event than female controls (70.2 vs 24.5%, P < 0.001), no significant difference was found when comparing male RA patients with male controls (26.9 vs 18.5%, respectively, P = 0.46). Increased perceived stress score (P = 0.04) and coping based on emotions (P = 0.001) were found in cases compared with controls. Conclusion Patients with early RA reported more life events in the year preceding the onset of symptoms than controls. Gender specificities were found with a significant association between cumulative stress and RA only in women.

  Tropheryma whipplei is the bacterial agent responsible for Whipple’s disease (WD). However, WD occurs only very rarely in T. whipplei-infected individuals. We investigated the cause of disease in two relatives with WD. We studied a son and his mother, both presenting an articular form of WD, at the ages of 38 and 60 years, respectively, these episodes occurring five years apart. Both were otherwise healthy. We performed whole-exome sequencing, characterized a candidate variant biochemically, and performed an immunological analysis on the patients’ leukocytes. Both patients were heterozygous for a rare missense variant of the gene encoding the transcription factor IRF4 (p.R25S), for which haploinsufficiency was previously reported to underlie WD in a large multiplex family. This variant was hypomorphic for DNA binding and transcription induction. It did not exert negative dominance. Immunity was otherwise normal in these two patients. Haploinsufficiency for IRF4 can thus underlie WD in T. whipplei–infected individuals from at least two unrelated families.
