Non-tumor features

IgA deficiency, selective


This is the most common type of immunodeficiency, characterized by a selective defect in IgA production. The origin is probably heterogeneous and the disorder is associated with other conditions, celiac disease is the most frequent of those.[16].

There appears to be an increased risk to develop gastric adenocarcinoma in patients with this disorder[1;2] and possibly there is an increased risk to develop Hodgkin disease and Non-Hodgkin lymphoma as well[2-4,15]. In a review by Filopovich et al.[4], approximately 8 % of IgA deficiency patients were reported to have developed a tumor. In a cohort of cancer patients, selective IgA deficiency has been detected in a higher frequency than in the general population, especially in the patients with lymphoproliferative disease and gastrointestinal cancer[5].

Schuelke et al.[6] reported on a family with multiple cases of ovarian cancer segregating with low serum IgA levels. Abdominal wall fibrosarcoma in a 17-year-old girl with IgA deficiency was reported by Verkasalo et al.[7]. Kuhn[8] reported on a 45 year old woman with a selective IgA deficiency and alcohol and tobacco abuse, who developed oral cancer. A range of other tumors has been reported as well[9-12].
Hamoudi et al.[13] reported a girl who developed multiple adenomatous polyps in her colon (1 malignant) at the age of 10, after which she developed over a period of 8 years a malignant thymoma, squamous cell cancer of the scalp, colon cancer, choroidal tumor, finally dying at the age of 20 from a brain tumor (astrocytoma). She had low Ig A and IgG2 levels, normal IgM and total IgG. Her brother had a total absence of IgA, low IgG and high IgM and died at the age of 16 from a lymphocytic lymphoma. Although this family was reported with an emphasis on the IgA deficiency, there is no selective IgA deficiency (possibly a variant of Hyper-IgM syndrome? Epstein-Barr virus infections may play a role in tumor development in patients with IgA deficiency[14]
