Transient hypogammaglobulinemia of infancy: predictive factors for late recovery.

چکیده
This study evaluates the clinical/immunological features and outcomes of 91 patients with the diagnosis of transient hypogammaglobulinemia of infancy(THI). Mean age at diagnosis was 8.4±5.2 months. IgG levels normalized at 30.6±11.88 months. Sixty three patients (69.3%) resolved in their first 3 years of life and 28 patients (30.7%) thereafter. In the univariate analysis, presence of atopy, occurrence of recurrent infections (>6/year) and hospitalization, initial low IgA and IgM levels were found to be associated with the late recovery. Patients with longer breastfeeding duration recovered earlier. Recovery time for Ig levels was found to be longer in patients who received IVIG (n=55, 60.4%). This study confirmed that delayed resolution in THI is not rare. Frequent infections, initial low IgA and/or IgM levels and presence of atopy were found as associated factors for the late recovery. Breastfeeding should be encouraged and IVIG should be used in well selected patients.

Does Intravenous Immunoglobulin Therapy Prolong Immunodeficiency in Transient Hypogammaglobulinemia of Infancy?
Transient hypogammaglobulinemia of infancy (THI) is characterized by recurrent infections and one or more reduced serum immunoglobulin levels. Typically, THI patients recover spontaneously, mostly within 30-40 months of age, but sometimes recovery may be delayed until 5-6 years of age. The use of intravenous immunoglobulin (IVIg) as an alternative to antibiotic prophylaxis remains contraversial...

BACKGROUND Symptomatic hypogammaglobulinemia in infancy and childhood (SHIC), may be an early manifestation of a primary immunodeficiency or a maturational delay in the normal production of immunoglobulins (Ig). We aimed to evaluate the natural course of SHIC and correlate in vitro lymphoproliferative and secretory responses with recovery of immunoglobulin values and clinical resolution. METH...

BACKGROUND Patients with transient hypogammaglobulinaemia of infancy (THI) may have mild infections or be asymptomatic. About 20% of THI patients have very severe and recurrent infections and receive intravenous immunoglobulins (IVIg) for replacement therapy and infection prophylaxis. It is still not clear why some THI patients are severely symptomatic; it has been suggested that there might be...

Transient hypogammaglobulinemia of infancy (THI) is characterized by a prolongation and accentuation of the physiologic hypogammaglobulinemia normally occurring during the first 3 to 6 months of life and recovers spontaneously between 18 and 36 months of age. Infants with THI may remain asymptomatic or develop recurrent sinopulmonary infections, but severe or life-threatening infections are rar...
