- Objective: Small airway disease and chronic obstructive pulmonary disease are common in primary Sjogrens syndrome (pSS). However, the underlying inflammatory mechanisms behind pSS-associated airway disease have not been studied in detail. We therefore wanted to study cytokine and leucocyte levels in induced sputum in never-smoking patients with pSS. Method: Induced sputum cytokines and leucocytes were assessed in 20 never-smoking patients with pSS and 19 age- and gender-matched population-based controls. In addition, pulmonary function, disease activity, respiratory symptoms, and inflammatory and serological features of pSS were assessed. Results: B-cell activating factor (BAFF), interleukin-6 (IL-6) and IL-8 were significantly increased in induced sputum in pSS patients compared to population-based controls, while IL-1 beta, interferon-alpha, and tumour necrosis factor-alpha levels and leucocytes were not. The proportion of lymphocytes and BAFF levels in induced sputum correlated significantly in pSS patients. However, cytokine levels in induced sputum were not associated with pulmonary function tests, disease activity, respiratory symptoms, or serological features of pSS. Conclusion: The increase in BAFF, IL-6, and IL-8 in induced sputum suggests a specific ongoing inflammatory disease process in the airways in pSS patients. Its association with pSS-associated airway disease needs to be further examined in future larger studies.

- Objective: To investigate Raynaud’s phenomenon (RP) and its impact on daily life activities during 1 year of follow-up in early systemic sclerosis (SSc). Method: Fourteen SSc patients with a median disease duration of 2 years were enrolled in the study. Every 7 weeks the patients completed a 7 day diary documenting the frequency and duration of RP attacks, the activity causing the attack, and how they handled the attack. The patients also recorded in the diary daily self-assessments of the difficulties with RP, using a 0–10 ordinal scale according to the Raynaud’s Condition Score. Results: Ninety-eight RP weekly diaries were analysed. The median number of RP attacks varied between six and nine per week, and the median score reflecting the difficulty associated with the attacks varied between 2.0 and 2.9. No difference was found in the number of attacks or the difficulties associated with them between winter, spring, and autumn. Fewer attacks and less difficulty were reported in August than in any of the other documented weeks (p < 0.05). In all diaries, all patients reported RP attacks associated with domestic activities. The use of heating devices varied during the follow-up. In February, all patients except one used such devices, while about half of the group used devices during the rest of the year. Conclusions: Difficulties resulting from RP are present and disabling all year round, which underscore the importance of intense vasoactive therapy and non-pharmacological strategies throughout the year.
