They have been recently reported to be associated with increased mortality in Spanish patients with RA. The aim of our study was to compare the incidence mortality rates (IMRs) detected in RA patients from a tertiary Italian center with those reported in other European tertiary centers and to evaluate the putative role of anti-CarP Ab in modulating the low IMR detected in our patients.Methods: Clinical charts of patients consecutively admitted to our center, from January 1, 2008, to December 31, 2014, were retrospectively reviewed. The mortality rate (expressed as the number of deaths in the cohort divided by the number of years of IMR follow-up) and causes of death were assessed at December 31, 2015. Sera of 61 patients, representative of the whole cohort, collected at the time of admission to our center were investigated for the presence and the level of anti-CarP Ab. Demographic and clinical features, mortality rates and prevalence of anti-CarP Ab in our series were compared with those reported in other European cohorts.Results: We observed 608 patients for a median of 3.51 years. All-cause and cause-specific IMRs in our cohort were significantly lower than the Better Anti-rheumatic Farmaco-therapy and the Spanish cohort, while only all-cause and cardiovascular IMRs were significantly lower in our series with respect to the Leiden Early Arthritis Clinic cohort. Anti-CarP Ab prevalence was significantly lower in our series than in any other European cohorts.Conclusion: We confirm that the mortality rate is lower in our Italian RA cohort with respect to other European cohorts. Whether the low prevalence of anti-CarP Ab might be responsible for this result awaits to be furtherly investigated.

This study is devoted to investigating all the distinct causes of mortality in Italian RA patients.Methods: Clinical charts of patients consecutively admitted to an Italian tertiary center, from January 1, 2008 to December 31, 2014, were reviewed. Mortality rates (incidence mortality rate [IMR] and standardized mortality rate [SMR]) and causes of death as assessed at December 31, 2015, were registered. Mortality rates detected in our series were compared to those reported in other European cohorts and in the general Italian population.Results: Six hundred and eight patients were observed for a median of 3.51 years. Overall IMR was 0.79 deaths/100 person-years. No significant difference between our IMR and that reported in Italian population by the National Institute of Statistics was observed. All-cause and neoplasm IMRs in our series were found to be significantly lower than that reported in the Norfolk Arthritis Registry, while no difference was detected in cardiovascular (CV) mortality. On the other hand, all causes and CV SMRs in our series were found to be higher than that reported in the general Italian population, while cancer and infectious SMRs were found to be lower.Conclusion: In our series, RA patients had an increased all-cause mortality, and in particular an increased death rate due to CV. However, a lower death rate due to cancer and infections was observed. This figure might be due to the careful follow-up of RA patients in tertiary centers, and the results underlines the need to improve the management of CV risk.
