Primary immunodeficiencies : Report of 33 Pediatric Tunisian cases.

Background Primary immunodeficiencies (PID) are a group of heterogeneous and relatively rare diseases. Aim to determine the clinical characteristics, outcome and genetic data of primary immunodeficiencies in pediatrics patients. Methods A retrospective, descriptive and multicentered study, enrolling 33 children presenting a PID in Tunis, during a period of 22 years (1991-2012).

Ataxia-telangiectasia in the south of Tunisia: A study of 11 cases.

Background: Ataxia-telangiectasia (A-T) is a multisystem disorder characterized by progressive neurologic impairment, variable immunodeficiency, impaired organ maturation, X-ray hypersensitivity, oculocutaneous telangiectasia, and a predisposition to malignancy.

Aim: We performed this study in order to describe clinical, immunological and molecular features of patients with AT followed in the south of Tunisia Methods: we performed a retrospective study (1996-2012) in the south of Tunisia about all cases of A-T in order to describe their clinical, immunological and molecular features.

Results: 11 cases of AT were found.

Leukocyte adhesion deficiency (LAD) is a rare primary immunodeficiency inherited as an autosomal recessive genetic disorder. LAD was suspected in a four days old girl. She was born from healthy first cousins.
