Objective: We aimed to quantify the mortality risk in a large, well-characterized cohort of patients with Sjögren disease (SjD) and to identify independent predictors of mortality in this population.Methods: We included 314 patients diagnosed with SjD according to the 2002 American-European Consensus Group criteria from a prospective, multicenter SjögrenSER Prospective cohort. Detailed data on systemic manifestations, serological markers, disease activity, and mortality were collected after a median of 9.5 (IQR 9.2-9.9) years of follow-up. The primary outcome was overall mortality, and secondary analyses aimed to identify independent predictors of mortality using Cox proportional hazards models. Standardized mortality ratios were calculated by comparing the observed deaths in the SjD cohort to the expected deaths in an age- and sex-matched general population.Results: The study identified a 70% increased mortality risk in the SjD cohort compared to the general population, with a standard mortality ratio of 1.7. Infections (35.7%), malignancies (23.8%), and cardiovascular disease (CVD; 7.1%) were the most common causes of death. Multivariate analysis revealed that older age (HR 1.11/year, 95% CI 1.07-1.15), C4 hypocomplementemia (HR 3.75, 95% CI 1.55-9.06), elevated erythrocyte sedimentation rate (ESR; HR 1.01, 95% CI 1.00-1.03), history of heart failure (HR 4.24, 95% CI 1.02-17.58), and pulmonary involvement (HR 3.31, 95% CI 1.39-7.88) were independent predictors of mortality.Conclusion: This study found a significantly increased mortality risk in SjD, with infections, malignancies, and CVD as leading causes of death. Independent predictors of mortality include advanced age, C4 hypocomplementemia, elevated ESR, heart failure, and pulmonary involvement, underscoring the need for proactive, individualized management.

Objectives: To estimate the prevalence of psoriatic arthritis (PsA) and associated factors in patients with moderate-to-severe psoriasis. Methods: Retrospective, single-center study of a cohort of psoriasis patients in standard follow-up in a dermatology department from July 2008 to January 2024. Patients ≥18 years with moderate-to-severe psoriasis were included and classified into three groups according to the treatment received: group 1, biologics or small molecules with or without conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs); group 2, only csDMARDS; and group 3, non-pharmacological treatments. Demographic and clinical variables were collected. The prevalence of PsA was estimated with its 95% confidence interval (CI). The cumulative incidence of PsA was analyzed across groups, and logistic regression models were built. Results: The study population comprised 308 patients (67.2%, 22.7%, 10% in groups 1, 2, and 3, respectively). Differences between the groups were observed in severity of psoriasis, weight, smoking status, and dyslipidemia (p < 0.05). The prevalence of PsA was 11.7% (95% CI, 8.1–15.3), with most patients in group 1. This group had a higher risk of PsA following diagnosis of psoriasis or initiation of treatment. Belonging to groups 2 and 3 had a smaller effect than belonging to group 1 in the development of PsA; nail involvement and obstructive sleep apnea (OSA) were associated with development of PsA (p < 0.05). Conclusions: The prevalence estimate was lower than previous estimates, probably owing to the increased use of biologics. Nail involvement and OSA were associated with PsA.

Methods: Retrospective, single-center study of a cohort of psoriasis patients in stand-ard follow-up in a dermatology department from July 2008 to January 2024. Patients ≥18 years with moderate-to-severe psoriasis were included and classified into 3 groups according to the treatment received: group 1, biologics or small molecules with or without conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs); group 2, only csDMARDS; and group 3, non-pharmacological treatments.

Belonging to groups 2 and 3 had a smaller effect than belonging to group 1 in the development of PsA; nail involvement and obstructive sleep apnea (OSA) were associated with development of PsA (p< 0.05). Conclusions: The prevalence estimate was lower than previous estimates, probably owing to the increased use of biologics. Not requiring biologics for disease control had less effect on development of PsA. Nail involvement and OSA were associated with PsA.
