    Abstract Background: Despite the use of alfacalcidol in the management of corticosteroid-induced osteoporosis, it has never been considered an adjunct treatment for asthma management. It can target vitamin D deficiency, a possible risk factor for asthma, and, hence, improve pulmonary function of patients with asthma.
    Objective: To explore the effect of alfacalcidol administration on pulmonary function and study the pattern of vitamin D deficiency in adults with asthma in Egypt.
    Methods: Serum 25-hydroxyvitamin D was measured in 115 adults: 33 healthy subjects and 82 patients with asthma. Then, patients with asthma were randomized to receive standard asthma treatment only (n = 39) or receive it in addition to 1 μg of alfacalcidol daily for 4 months (n = 43). Randomization was stratified by the stage of asthma severity. Spirometry and measurement of 25-hydroxyvitamin were performed at baseline and end of follow-up.
    Results: Vitamin D deficiency was more common in patients with asthma (57.3%) than in healthy subjects (21.2%; P < .001). In patients with asthma, alfacalcidol significantly improved forced expiratory volume in the first second and forced vital capacity (P < .001 for the 2 tests). Moreover, more patients in the intervention arm showed improvement in asthma severity stage (P = .04). A nonsignificant difference was observed in improvement of forced expiratory volume in the first second between patients with vitamin D deficiency and those without deficiency in the intervention group (P > .05).
    Conclusion: Alfacalcidol supplementation improved the pulmonary function and severity stage of adult patients with asthma regardless of deficiency.

    Abstract The third volume in the groundbreaking new series "Theory in the World", Neighborhood and Boulevard combines memoir, history, anthropology, and theory to offer an innovative reflection on the materiality of culture. Through its style and content, the text challenges the Orientalist bifurcation between tradition and modernity in the Arab world, revealing instead tradition's own dynamism and its coexistence alongside modernity
