Odontogenic deep neck space infection in a patient with hyper-IgE syndrome: A case report

Hyperimmunoglobulin E syndrome is a primary immunodeficiency state that is characterized by eczema, recurrent skin and lung infections, and markedly increased levels of IgE. Odontogenic infection can spread to vital and deep structures in such immunocompromised patients. We report a case of a 19-year-old man with hyperimmunoglobulin E syndrome presenting deep neck space infection that had spread from periapical periodontitis of the lower molars. A computed tomography scan showed an area of bony destruction in the left mandible and abscess formation in the submandibular and submental spaces. The patient was successfully treated by cervical drainage, extraction of the causative teeth, and antibiotic therapy. The present case highlights the importance of adequate treatment of dental infections in immunocompromised patients. Key words:Hyperimmunoglobulin E syndrome, odontogenic infection.

Periodontal and other oral manifestations of immunodeficiency diseases

The list of immunodeficiency diseases grows each year as novel disorders are discovered, classified, and sometimes reclassified due to our ever-increasing knowledge of immune system function. Although the number of patients with secondary immunodeficiencies (SIDs) greatly exceeds those with primary immunodeficiencies (PIDs), the prevalence of both appears to be on the rise probably because of scientific breakthroughs that facilitate earlier and more accurate diagnosis. Primary immunodeficiencies in adults are not as rare as once thought. Globally, the main causes of secondary immunodeficiency are HIV infection and nutritional insufficiencies. Persons with acquired immune disorders such as AIDS caused by the human immunodeficiency virus (HIV) are now living long and fulfilling lives as a result of highly active antiretroviral therapy (HAART). Irrespective of whether the patient's immune-deficient state is a consequence of a genetic defect or is secondary in nature, dental and medical practitioners must be aware of the constant potential for infections and/or expressions of autoimmunity in these individuals. The purpose of this review was to study the most common conditions resulting from primary and secondary immunodeficiency states, how they are classified, and the detrimental manifestations of these disorders on the periodontal and oral tissues.

Otolaryngologic manifestations of immunodeficiency

Otolaryngologists are frequently consulted to manage infectious and noninfectious complications of immune deficiency. Although defects of host defense and recurrent or severe infections are the most obvious manifestations of immune deficiency, patients are often at increased risk for autoimmune and malignant disease as well. Knowledge of primary and acquired immune deficiencies will facilitate appropriate identification, treatment, and referral of patients with these defects. When immunodeficiency is known or suspected, it is particularly important to have a high index of suspicion for unusual or severe manifestations of infection, to have a low threshold for obtaining imaging to aid in diagnosis, and to treat infections for longer periods of time with higher doses of antibiotic. Surgery may be required for definitive treatment of infections that do not respond to medical therapy and for management of complications of infectious disease

Oral manifestations of primary immunological diseases

BACKGROUND

Primary immunodeficiencies have many oral manifestations. The clinical presentation of these diseases demonstrates the roles of different immune cells for the maintenance of oral health.

METHODS

The authors reviewed selected literature describing systemic and oral manifestations of the primary immunodeficiencies published between 1966 and 1999.

RESULTS

The authors found that oral candidiasis and herpetic infections are seen frequently in patients with T-cell deficiencies, while patients with B-cell deficiencies are most susceptible to bacterial infections. Periodontitis and oral candidiasis are found in some, but not all, phagocyte deficiencies.

CONCLUSIONS

These findings demonstrate that T cells, B cells and phagocytes all have roles in oral immunity.

CLINICAL IMPLICATIONS

Acquired conditions that affect the immune system such as diabetes, alcoholism and acquired immunodeficiency syndrome, as well as certain medications, will affect oral defense mechanisms. The effects that acquired immunodeficiencies will have on oral health can be predicted from the oral manifestations of primary immunodeficiencies.

Delayed eruption of permanent teeth in hyperimmunoglobulinemia E recurrent infection syndrome

OBJECTIVE

To determine the incidence of abnormal tooth eruption in patients with hyperimmunoglobulinemia E (hyper-IgE) syndrome.

STUDY DESIGN

This study evaluated 34 individuals with hyper-IgE syndrome (age range, 2-40 years). A comprehensive dental history and a head and neck evaluation were performed on all patients. Dental age was assessed in patients younger than 17 years by 2 methods: (1) clinical assessment of tooth eruption and (2) a radiographic method. Relationships between the chronologic age, dental developmental age, and age at tooth eruption were determined. Other oral or dental anomalies were recorded.

RESULTS

Of patients older than 7 years, 75% reported problems with permanent tooth eruption, as evidenced by retained primary teeth or the need for elective extractions of primary teeth to allow eruption of permanent teeth. None of the patients experienced problems with eruption of primary teeth. Eruption of the first and second permanent molars also occurred on time. Dental maturity scores were established for 14 patients 17 years of age or younger. In each case, the difference between chronologic age and the estimated dental developmental age was less than 12 months; however, we found a significant discrepancy between the chronologic age and the mean age of tooth eruption in 80% of these patients when using a particular set of standardized values. Persistence of Hertwig's epithelial root sheath was observed on histologic examination. Chronic multifocal oral candidiasis was a consistent feature in patients with hyper-IgE recurrent infection syndrome. Other oral anomalies were also noted.

CONCLUSION

We confirmed that a disorder of tooth eruption is part of the hyper-IgE syndrome. This problem occurs because of delayed primary tooth exfoliation rather than a developmental delay in the formation of the permanent dentition. The persistence of Hertwig's epithelial root sheath is unusual and may be associated with the lack of resorption of the primary teeth. Dentists should be aware of this feature of hyper-IgE syndrome because timely intervention will allow normal eruption to occur.

[Hyperglobulinemia E syndrome with recurrent infections (Job's syndrome)]

INTRODUCTION

To provide definition and nosology of hyperimmunoglobulinemia E previously termed Job's syndrome or Buckleys' syndrome in the literature. Generalization of IgE dosages makes it more commonly diagnosed, though sometimes diagnosis may not be accurate.

CURRENT KNOWLEDGE AND KEY POINTS

The clinical picture is dominated by recurring cutaneous and visceral bacterial infections, particularly infections due to staphylococci, and severe generalized eczema, which may be associated with osteoporosis. Biochemistry includes a high level of total and specific IgE and immunological abnormalities dominated by frequent absence of immune antibodies to staphylococci and disorders of neutrophil chemotaxis. Current pathogenic studies show dysregulation of TH1 and TH2 lymphocytes in favor of TH2 activation with depressed TH1 activation, leading to an imbalance in cytokine synthesis.

FUTURE PROSPECTS AND PROJECTS

New therapeutical possibilities with alpha and gamma interferon.
