Subcutaneous allergen immunotherapy for asthma: A randomized, double-blind, placebo-controlled study with a standardized vaccine.

Background: Sensitization to () is very frequent in the tropics, and particularly in Cuba, being a significant cause of allergic asthma. Allergen immunotherapy (AIT) with can be a therapeutic option, however, placebo-controlled clinical trials have not been reported.

Objective: To assess the therapeutic effect and safety of AIT for asthma using a standardized allergen vaccine of by subcutaneous route, in allergic asthmatic patients exposed and sensitized to this mite species.

[Sensitivity and specificity of prick skin test with two concentrations of standardized extract of Culex quinquefasciatus in allergic children].

Background: Diagnostic options for immune reactions to mosquito bites are limited. In Cuba, IgE-mediated reactions are frequently related to Culex quinquefasciatus bite.

Objective: To determine the sensitivity and specificity of skin prick test with two doses of standardized extract in nitrogen protein units (PNU of Culex quinquefasciatus (BIOCEN, Cuba).

[Sensitization to three species of mites in allergic patients from the coastal area of Havana city].

Background: Sensitization to three allergic mite species (Dermatophagoides pteronyssinus, Dermatophagoides siboney and Blomia tropicalis) from house dust in Cuba has been reported in different studies.

Objective: To assess allergic sensitization to these mites in a north coast area of Havana city.

Patients And Methods: A total of 210 allergic patients were selected, classified in two groups: from 1 to 14 years, and from 15 to 55 years.
