Immunodeficien cies and their oral manifestations Done by : Mohammad salah qrea 5th year And presented to Dr. fahed habash
Immunity • A complex interaction of certain types of cells. • Innate immunity with born vs. adaptive immunity along time.
Innate immunity
Interferons Phagocytes Skin
Complement system
IMD disorders • Part of the body's immune system is missing or defective. • impairing the body's ability to fight infections. • As a result, the person with an IMD will have frequent infections that are generally more severe and last longer than usual.
Types of IMDs • Primary or congenital ID. • Acquired ID.
Primary IMD • Congenital disorder of one or more of immune system. • T and B cell defects. • Phagocytes defects. • IgA deficiency.
Acquired IMD • Infections (HIV, chicken pox, German measles, measles, tuberculosis, chronic hepatitis, lupus, bacterial and fungal infections). • Malnutrition (vitamins, iron, and zinc). • Some cancers. • Some drugs. • Some metabolic diseases. • Alcoholism.
Prevention of AIMDs • Good nutrition. • Avoiding responsible infections. • And safe sex “ for AIDS prevention, IF YOU DON’T KNOW YOUR PARTNER USE CONDOM” • Illegal intravenous drugs.

Bacterial infections
Phagocyte deficiency
Periodontitis + candidal

leukocyte adhesion deficiency
Treatment modalities • Bone marrow transplantation. • Prophylactic antibiotic regimens. • Aggressive preventive dental care.
Secondary immunodeficiency oral manifestations
Acquired immunodeficiency syndrome Causative agent: HIV Target cells: CD4+ T cells, monocytes, macrophages, dendritic cells, etc. Importance of gp120
• Diagnosis: detection of viral Ag, antiviral Ab • Prognosis: CD4/CD8 ratio, skin tests (DTH), Lymphocyte transformation test • Treatment: • 1. Treatment of microbial infections • 2. Anti-viral drugs • 3. Immunorestoration: BM transplantation, Ig injections, cytokines
Oral manifestations of
AIDS
• Fungal Candidiasis Pseudomembranous Erythematous Angular cheilitis Histoplasmosis Cryptococcosis. • Viral Herpes simplex Herpes zoster Human papillomavirus lesions Cytomegalovirus ulcers Hairy leukoplakia • Bacterial Linear gingival erythema Necrotizing ulcerative Periodontitis Mycobacterium avium complex Bacillary angiomatosis • Neoplastic Kaposi's sarcoma Non-Hodgkin's lymphoma • Other Recurrent aphthous ulcers Immune thrombocytopenic purpura HIV salivary gland disease.
CANDIDIASIS • Exfoliative cytology, biopsy for diagnosis. • TREATED BY: • Topical antifungal (e.g., nystatin [Mycostatin]. • Suspension, clotrimazole [Mycelex] troches, fluconazole [Diflucan] suspension. • Or systemic antifungal (e.g., fluconazole, ketoconazole [Nizoral], itraconazole [Sporanox])

Recurrent aphthous stomatitis • Yellowish white pseudomembrane surrounded by erythematous zone. • Treated by: • Fluocinonide gel (Lidex) or triamcinolone acetonide (Kenalog in Orabase), amlexanox paste (Aphthasol), chlorhexidine gluconate (Peridex) mouthwash.

Hairy tongue • Elongated filiform papillae. • Predisposing factors, smoking, poor oral hygiene, antibiotics and psychotropics. • TREATED BY: • Regular tongue brushing or scraping; avoidance of predisposing factors

VIRUSES
Recurrent herpes labialis • Prodrome, 12 to 36 hours, rupture vesicles. • Reactivation triggers: ultraviolet light, trauma, fatigue, stress, menstruation. • TRAETED BY: • Topical agents include 1% penciclovir cream (Denavir) • Systemic agents (e.g., acyclovir [Zovirax], valacyclovir [Valtrex], famciclovir [Famvir]) are most effective if initiated during prodrome.
