Specific immunotherapy in children under five years of age with the extract used is safe. We consider that further studies are needed, involving other types of extracts, to allow reconsideration of the relative contraindication of patient age for the administration of immunotherapy.

Background: Since 2003, the Remediar (+Redes) program supplies free anti-hypertensive medication. During this period, mortality from stroke has decreased, albeit with inequalities between socioeconomic groups. Objectives: The aim of this study was to assess the association between stroke mortality and the provision of antihypertensive drugs and to study the possible interaction between antihypertensive effects on mortality and socioeconomic status. Methods: An ecological panel data study was performed. Mortality was expressed as standardized rates. Antihypertensive drugs were adjusted among the population to whom they were provided and expressed in dispensing quartiles. Socioeconomic status was measured by unmet basic needs. Results: Since the program's initiation in 2003, the distribution of antihypertensive drugs increased significantly, especially in the less affluent groups (p<0.001). There was no statistically significant association between antihypertensive drug dispensing rate and overall stroke mortality. However, the interaction analyses showed that in quintiles 3 to 5 of unsatisfied basic needs (less affluent), the quartiles in which more antihypertensive drugs were distributed, had significantly lower mortality from stroke (p=0.004, p=0.015 and p=0.017, respectively). Conclusions:The results of this analysis indicate no antihypertensive drug dispensing overall effect on stroke mortality. However, data suggest that among the most disadvantaged groups, the distribution of antihypertensive drugs was associated with a reduction in mortality from this cause.
