Value of serum soluble interleukin-2 receptor as a diagnostic and predictive biomarker in sarcoidosis.

BACKGROUND: Differentiating between interstitial lung diseases (ILD) is challenging. Serum soluble interleukin 2 receptor (sIL-2R) is used as a diagnostic marker in sarcoidosis, but its diagnostic value has not yet been studied in other ILDs like Idiopathic Pulmonary Fibrosis (IPF) or Hypersensitivity Pneumonitis (HP). Also, the prognostic value of sIL-2R in sarcoidosis remains unknown. METHODS: This retrospective cohort study included 121 patients with sarcoidosis, 35 with cHP, 62 with IPF (idiopathic pulmonary fibrosis) and 70 healthy controls. Serum sIL-2R levels were determined at diagnosis. Follow-up data were available for patients with chronic sarcoidosis (n = 64) and patients with non-chronic sarcoidosis (n = 29). RESULTS: Patients with sarcoidosis had higher sIL-2R levels (median 5418 pg/mL) than patients with cHP (median 4015 pg/mL, P = 0.002) and IPF (median 4192 pg/mL, P = 0.034). No differences were found between patients with cHP and IPF. Logistic regression revealed that sIL-2R at diagnosis is a significant predictor of the development of chronic sarcoidosis (OR = 2.1, P = 0.032). CONCLUSION: High levels of sIL-2R are suggestive of sarcoidosis, although a broad overlap exists in sIL-2R levels across sarcoidosis, cHP, and IPF. High levels of sIL-2R might serve as a prognostic biomarker for chronicity.

Developing a policy game intervention to enhance collaboration in public health policymaking in three European countries.

BACKGROUND: One of the key elements to enhance the uptake of evidence in public health policies is stimulating cross-sector collaboration. An intervention stimulating collaboration is a policy game. The aim of this study was to describe the design and methods of the development process of the policy game 'In2Action' within a real-life setting of public health policymaking networks in the Netherlands, Denmark and Romania. METHODS: The development of the policy game intervention consisted of three phases, pre intervention, designing the game intervention and tailoring the intervention. RESULTS: In2Action was developed as a role-play game of one day, with main focus to develop in collaboration a cross-sector implementation plan based on the approved strategic local public health policy. CONCLUSIONS: This study introduced an innovative intervention for public health policymaking. It described the design and development of the generic frame of the In2Action game focusing on enhancing collaboration in local public health policymaking networks. By keeping the game generic, it became suitable for each of the three country cases with only minor changes. The generic frame of the game is expected to be generalizable for other European countries to stimulate interaction and collaboration in the policy process.
