Selective IgA deficiency (SIgAD) is the most prevalent immunodeficiency worldwide, progressing to common variable immunodeficiency only in few reported cases. We report the case of a Spanish female aged 22 and diagnosed of selective IgA deficiency, a long history of bronchitis, several episodes of pneumonia, bilateral bronchiectasis, normal IgG, IgM, IgG subclasses, and detectable pre-vaccination IgG antibodies against tetanus toxoid and Streptococcus pneumoniae. She was evaluated in our clinic in order to rule out common variable immunodeficiency. We observed good antibody response to tetanus toxoid, absence of circulating switched memory B cells, decreased response to pneumococcal polysaccharide antigens and a lack of response to Salmonella typhi vaccine. Most SIgAD patients presents with upper respiratory tract infections or mild diarrhea. Those with lower tract infections, pneumonia or untreatable diarrhea should follow B-cell subpopulations' study and antibody response to vaccines. Absence of response to Salmonella typhi vaccine allowed us to expose the defective antibody production.
