Work productivity and activity impairment in patients with primary Sjögren's syndrome.

OBJECTIVES: In this observational, analytical, cross-sectional study we aimed to describe the impact of primary Sjögren's syndrome (pSS) on work productivity and activities of daily living (ADL) to assess the association between ADL impairment and clinical manifestations and to compare ADL impairment according to patients' socioeconomic condition. METHODS: Patients diagnosed with pSS attending 11 centres from Argentina were included. To evaluate work productivity and ADL impairment, a work productivity and activity impairment questionnaire (WPAI) was used. A multiple linear regression model was performed, considering deterioration on ADL due to health as a dependent variable, adjusted for potential confounders. RESULTS: 252 patients were included, 98.4% were women, with a mean age of 52.6 years (±14.8). The average percentage of time lost due to health was 15.7 hours (±30.1 95% CI: 9.6-21.9); the decrease in work productivity was 27.2 (±30.2 95% CI: 21.3-33.1), the total disability was 33.7 (±35.8 95% CI: 26.4-4) and ADL deterioration was 34.2 (±30.9. 95% CI: 30.4-38). In the multivariate analysis, xerostomia, arthritis and depression showed significant and independent association. The mean of ADL impairment was 38.2 (±30.7) in patients attending public centres versus 28 (± 30.6) in private centres, which was a statistically significant difference. CONCLUSIONS: We found a compromise in all WPAI domains. Arthritis, xerostomia and depression were associated significantly and independently with ADL impairment. Deterioration in ADL was greater in patients treated in public centres. Considering these aspects will allow a better understanding of patients who suffer from this disease.

Hallazgos capilaroscópicos y características clínicas en pacientes con fenómeno de Raynaud primario y secundario / Capillaroscopic findings and clinical characteristics in patients with primary and secondary Raynaud's phenomenon

Objetivos: describir hallazgos de videocapilaroscopía (VCP) en pacientes con fenómeno de Raynaud primario (FRP) y secundario (FRS); comparar características demográficas y clínicas entre ambos. Materiales y métodos: estudio observacional, analítico, transversal. Se documentaron edad, ocupación, tiempo de evolución del FR, enfermedad del tejido conectivo (ETC) y características capilaroscópicas. Las VCP se informaron como patrón normal, inespecífico o SD temprano, activo y tardío. Se realizó estadística descriptiva. Para variables categóricas se empleó Chi² o test exacto de Fisher; para variables continuas, t test o Man Whitney, considerando estadísticamente significativa p<0,05. Resultados: se realizaron 290 VCP. En pacientes con FRP (n:122), 18% (n:23) fue normal y 81% (n:99) con patrón inespecífico. En pacientes con FRS (n:168), 8% fue normal, 42% con patrón inespecífico y 51% con patrón SD (25% temprano, 44% activo, 31% tardío). Se hallaron diferencias estadísticamente significativas: tiempo de evolución de FR en meses (12 vs 36, p<0,01), VCP normal (18,85% vs 7,4%, p<0,01), patrón inespecífico (81,14% vs 41%, p<0,01) en pacientes con FRP vs. FRS. Conclusiones: en pacientes con FRS predominó el patrón SD, mientras que en aquellos con FRP fue superior el patrón normal e inespecífico. El FRS se asoció a mayor tiempo de evolución.

Objectives: to describe videocapillaroscopy (VCP) findings in patients with primary Raynaud's phenomenon (PRP) and secondary (SRP); compare demographic and clinical characteristics between both. Materials and methods: observational, analytical, cross-sectional study. Age, occupation, evolution time of RP, connective tissue disease (CTD) and capillaroscopic characteristics were documented. The VCP were reported as normal, nonspecific or early, active, and late SD pattern. Descriptive statistics were performed. Chi² or Fisher's exact test were used for categorical variables; for continuous variables t test or Man Whitney, considering statistically significant p<0.05. Results: 290 VCP were performed. In patients with PRP (n:122), 18% (n:23) were normal and 81% (n:99) non-specific. In patients with SRP (n:168), 8% were normal, 42% non-specific and 51% with SD pattern (25% early, 44% active, 31% late). We found statistically significant differences: time of evolution of RP in months (12 vs. 36, p<0.01), normal VCP (18.85% vs 7.4%, p<0.01), non-specific pattern (81.14% vs 41%, p<0.01) in patients with PRP vs SRP. Conclusions: in patients with FRS predominated the SD pattern, while in those with FRP the normal and nonspecific pattern was superior. FRS was associated with a longer evolution time.
