Can patients with common variable immunodeficiency have allergic rhinitis?
In CVID patients, chronic rhinitis may be allergic, because many have personal and family histories suggestive of atopy. However, in this study, allergy was confirmed by specific IgE detection in only 5.6% of cases. CVID patients with a history suggestive of AR commonly present negative results on traditional testing, so additional experiments may be necessary. One suggestion for the investigation of AR in CVID patients would be nasal provocation with the most prevalent allergens.
These results indicate that breviscapine can improve the functions of spatial learning and memory of focal cerebral ischemia rats and the protection against the loss of ChAT immunopositive neuron in new cortex may be involved in its mechanisms.
