Davis Buckley Hyperimmunoglobulin E Syndrome associated With IgA Deficiency: The Second Case

Background: Davis Buckley hyperimmunoglobulin E (IgE), recurrent infection syndromes are very rare group of heterogeneous disorders of variable genetic basis and manifestations, but they are essentially characterized by significant elevation of serum IgE levels occurring in association with recurrent infections with or without coarse facial features and eosinophilia. The aim of this paper is to report the occurrence of an extraordinary case of Davis Buckley syndrome associated with associated with IgA deficiency. Patients and methods: An Iraqi boy of Turkish origins was referred at the age of 10 years to the pediatric psychiatry clinic at the Children Teaching Hospital of Baghdad Medical City because of poor school performance and poor attention span was studied. Results: The boy didn’t have coarse facial features or facial dysmorphism .During the previous few years the boy was experiencing urinary tract infections and recurrent ear infections associated with discharge and was being treated with several courses of antibiotics. The boy didn’t have growth retardation or bony or dental abnormalities. The parents were health relative, and family history was negative for similar condition. Blood tests showed eosinophilia and reactive thrombocytosis. Serum IgE was significantly elevated at the level of 0.4mg/dL (normal 0.01-0.04 mg/dL).The patient also had very low IgA level which was 18 mg/dL (normal 90-450 mg/dL). Mutation analysis was positive for Stat 3 mutation. Conclusion: There has been only one case of Davis Buckley syndrome associated with low IgA levels reported by Mazzone et al (1996). The case in this paper is most probably the second case of the syndrome associated with IgA deficiency.

The syndrome may also be associated with eczema, skeletal and dental abnormalities [1-4]. In 1966, Davis et al described two red-haired, fair-skinned girls who had infection sino-pulmonary, staphylococcal cutaneous infections, Elevated levels of IgE and defective of neutrophil chemotaxis. Davis et al thought that the condition could be similar to the affliction of Job, a biblical prophet whose body was covered with sore boils [1]. Buckley et.

Buckley hyperimmunoglobulin E (IgE), recurrent infection syndromes are very rare group of heterogeneous disorders of variable genetic basis and manifestations, but they are essentially characterized by significant elevation of serum IgE levels occurring in association with recurrent infections with or without coarse facial features and eosinophilia. The syndrome may also be associated with eczema, skeletal and dental abnormalities [1][2][3][4].

PATIENTS AND METHODS
An Iraqi boy of Turkish origins was referred at the age of 10 years to the pediatric psychiatry clinic at the Children Teaching Hospital of Baghdad Medical City because of poor school performance and poor attention span was studied.

RESULTS
The boy didn't have coarse facial features or facial dysmorphism ( Figure 1). During the previous few years the boy was experiencing urinary tract infections and recurrent ear infections associated with discharge and was being treated with several courses of antibiotics. The boy didn't have growth retardation or bony or dental abnormalities. The parents were health relative, and family history was negative for similar condition.

thrombocytosis is an extremely rare during childhood, while secondary or reactive thrombocytosis is commonly a reactive process caused by infection, chronic inflammation, and iron deficiency [5].
The dominant form Davis Buckley syndrome has generally been attributed to STAT-3 mutation with loss of function of the signal transducer and activator of transcription 3, while autosomal recessive forms are generally attributed to mutations in dedicator of cytokines 8 (DOCK-8) [6].
In this case, the occurrence of Davis Buckley syndrome without coarse facial features, but with eosinophilia and the presence of Stat 3 mutation suggest an overlap between the autosomal dominant and recessive forms. Mazzone et al. (1996), emphasized the rarity IgA deficiency in association with Davis Buckley syndrome. They reported a young woman with Davis Buckley syndrome who had recurrent urinary tract infectios, genital bacterial infections, generalized erythematous eczematous patches and stomatitis of oral mucosa and fever. The patient had high immunoglobulin IgE and low IgA levels [7].

CONCLUSION
There has been only one case of Davis Buckley syndrome associated with low IgA levels reported by Mazzone et al. (1996). The case in this paper is most probably the second case of the syndrome associated with IgA deficiency.  suggested the possibility of the existence of an autosomal dominant classical form of the syndrome, and an autosomal recessive form. The autosomal dominant hyper-IgE syndrome is associated with facial, dental, skeletal, and connective tissue abnormalities which are not reported in association with the recessive type [4].
During childhood, platelet counts range between 250 x 10 9 /L and x 10 9 /L. An elevated platelet count more than 500, 000109/L indicates the presence of thrombocytosis. Primary
