Transient hypogammaglobulinemia of infancy usually becomes symptomatic between 6 and 12 months of age [1] and is characterized by frequent upper respiratory and sometimes other types of infections: gastrointestinal, urinary or invasive [2] [3]. These consist of episodes of otitis, sinusitis, bronchitis, rhinopharyngitis, or, in rare cases, meningitis [4], severe varicella [5] or oral candidiasis. Lower respiratory tract infections are also encountered [5]. Allergic manifestations coexist in about half of the cases [1]: eczema, food allergy or intolerance [6], asthma and allergic rhinitis [7]. Seldom, patients are asymptomatic [8]. Gastrointestinal symptoms include chronic diarrhea and recurrent vomiting. Infections usually become less frequent after the patients turn 3 years old.

Clinical examination reveals normal sized or hypertrophic tonsils, adenoids or lymph nodes. Splenomegaly is present in approximately 25% of patients, more often in those with hyper-IgM syndrome. Lymphoid tissue is hyperplastic in intrinsic B-cell immune defects, which aids clinical differential diagnosis.

Transient hypergammaglobulinemia of infancy is characterized by certain laboratory hallmarks. Immunoglobulin G is two standard deviations below the mean value on at least two different occasions. Immunoglobulins A and M may also be diminished, but this is not a necessary trait. These abnormalities must resolve during childhood, for the "transient" term to apply. Antibody formation after infection or vaccination (both protein and polysaccharide [9] antigens) is normal [7], but may not persist over time [10]. Others argue that response to polysaccharide antigens may be diminished [11]. In permanent forms of hypogammaglobulinemia, antibody response to vaccine is insufficient.

Cellular immunity is usually not compromised. Memory B lymphocytes and class-switched B cells are normal [12] or decreased [13], while CD4 +CD25 highFoxP3 + T-regulatory (Treg) may be increased. Mitogen response is normal [14]. Immunoglobulin G formation can be impaired [15] or normal [16]. Some authors have also described patients with associated abnormalities, such as transient or permanent neutropenia or acute lymphoblastic leukemia. CD3+ and especially CD4+ T cells are often normal but may be decreased, while CD19+ B cell number may be increased. Lymphoproliferative responses are normal in vitro.

Other useful laboratory workup methods include determination of CD3+, CD4+, CD8+ T-cell percentages using flow cytometry and testing T cell function. This can be done by skin testing for antigens like Candida albicans and tetanus toxoid and by assessing lymphoproliferative responses to mitogens.

Infections may be diagnosed using a complete cell blood count and various imaging methods, like chest or sinus radiography or computed tomography.
