RESUMEN
INTRODUCTION: Severe asthma is associated with a serious disease burden, partially caused by limitations in activity and work impairment. AIMS AND OBJECTIVES: This study aims to relate treatment with biologics targeting IL-5/5Ra to work productivity and activity in the long term in a real-world context. MATERIAL AND METHODS: This is a registry-based multi-center cohort study evaluating data from adults with severe eosinophilic asthma included in the Dutch Register of Adult Patients with Severe Asthma for Optimal DIsease management (RAPSODI). Patients that started with anti-IL-5/5Ra biologics and completed the work productivity and activity improvement questionnaire, were included. Study and patient characteristics were compared between the employed and unemployed patients. Work productivity and activity impairment are related to accompanying improvements in clinical outcomes. RESULTS: At baseline, 91 of 137 patients (66%) were employed which remained stable throughout the follow-up period. Patients in the working age category were younger and had significantly better asthma control (p = 0.02). Mean overall work impairment due to health decreased significantly from 25.5% (SD2.6) to 17.6% (SD 2.8) during 12 months anti-IL-5/5Ra biologics treatment (P = 0.010). There was a significant association between ACQ6 and overall work improvement after targeted therapy (ß = 8.7, CI 2.1-15.4, P = 0.01). The improvement of asthma control of 0.5 points on the asthma Control Questionnaire was associated with an overall work impairment of -9%. CONCLUSIONS: Work productivity and activity in severe eosinophilic asthma improved after starting anti-IL-5/5Ra biologics. Clinically relevant improvement in asthma control was associated with an overall work impairment score of -9% in this study.

Blood gas analysis plays an important role in the initial assessment of a patient in the emergency ward. We present three different patient cases to illustrate when to opt for a venous or an arterial blood gas analysis. Arterial punctures are more painful and carry a higher risk of complications compared to venous punctures. It is possible to use a venous blood gas to screen for acute acid/base disturbances. Ventilatory compensation or anion gap cannot be calculated reliably with a venous blood gas. On the other hand, the diagnosis diabetic keto-acidosis can be made with a venous blood gas; this mode of sampling can also be used for lactate measurement at the emergency department as an independent prognostic marker for mortality. Venous blood gas analyses are not able to assess oxygenation. Pulse oximetry is a non-invasive alternative for arterial blood gas sampling. The use of a venous blood gas to assess a patient's ventilation is limited, whereas it can be used to diagnose carbomonoxide intoxication or methaemoglobinaemia.
