BACKGROUND: Although mild to moderate asthma is known to be Th2 driven, cytokines produced in refractory asthma might not fit the classical Th2 pattern. METHODS: The aim of our study was to assess the cytokine production by sputum and blood cells from 15 refractory asthmatics (American Thoracic Society Criteria) compared to 15 mild untreated and 17 moderate treated asthmatics and 22 healthy subjects. Spontaneous production of interleukin (IL)-4, IL-6, IL-10, interferon-gamma, and tumor necrosis factor alpha was measured by immunotrapping after 24 h sputum or blood cell culture. RESULTS: Moderate and refractory asthmatics were both characterized by a lower production of IL-6 from their airway cells compared to healthy subjects. However, the difference was no longer significant when expressing the results per gram of sputum. No significant difference between the three groups was found regarding other cytokines. As for cytokine production from blood, the three groups of asthmatics exhibited raised production of IL-4 when compared to healthy subjects, and this was true when results were expressed per blood volume or after normalization for total leukocyte cell count. Moderate asthmatics exhibited greater production of IL-10 when compared to refractory asthmatics and healthy subjects when results were normalized for total leukocyte cell count. CONCLUSIONS: Sputum cells from moderate and refractory asthmatics release less IL-6. While the systemic overproduction of IL-4 was observed through the all spectrum of asthma severity, moderate asthmatics exhibited greater systemic IL-10 production compared to refractory asthmatics.

Les différents spasmolytiques sont souvent prescrits par les médecins généralistes ou dans les services d’urgence dès que le diagnostic de colique néphrétique est posé. Une pratique cependant contestée. Cet article a pour but de faire une revue de la littérature de l’efficacité des spasmolytiques dans la colique néphrétique, et d’opposer celle-ci à la pratique quotidienne, ainsi que de faire le point sur les effets secondaires. Conclusion : la revue de l’EBM sur le sujet ne permet pas de prouver l’efficacité des spasmolytiques, et montre qu’il est préférable d’utiliser le diclofenac en monothérapie et de traiter les patients non contrôlés par tramadol et antalgiques. Il faudra adjoindre du tamsulosine pour les calculs du bas uretère. [less ▲]

Asthma and COPD (chronic obstructive pulmonary disease) are two pulmonary obstructive diseases. It is well recognized that inflammation plays a key role in the pathogenesis of these two diseases. However, inflammation per se does not entirely account for the progressive loss in pulmonary function. It is admitted that the functional changes partly relate to airway structural alteration called remodeling. In this review we summarize the most frequent tissue abnormalities found in patients with asthma and COPD and report on the relationship between structural alterations and clinical features of the disease.
