Autoimmune Disorders
Hashimoto’s Disease Rheumatoid Arthritis Sjogrens Syndrome Systemic Lupus Erythematosus
Hashimoto’s Disease
A chronic inflammatory disease of the thyroid
Incidence
Most common cause of primary thyroid deficiencies (thyroid “burns” out) Common in women and adolescents Familial predisposition
Laboratory Values
Assay the free thyroxine (T4) level Primary thyroid disease: TSH levels are elevated Secondary thyroid disease: caused by pituitary dysfunction and TSH level is normal or borderline
Medical Management
Thyroid hormone replacement once in the hypothyroid phase
Dental Management
Aggressively treat infections Avoid thyrotoxic crisis Closely monitor vitals Stress management
Rheumatoid Arthritis
A chronic nonsuppurative inflammatory destruction of the joints
Incidence
3% of general population Genetic predisposition Female to male ratio 3:1 Average age of onset of 40 years
Pathogenesis
Synovium is transformed into hyperplastic chronically inflammed tissue Intimal lining increases in size due to local proliferation of fibroblast-like cells and macrophage-like synoviocytes Prominent angiogenesis Rheumatoid factor is synthesized in the synovium and detected in synovial fluid
Signs and Symptoms
Polyarthritis sometimes associated with fever and weight loss Joint pain Generalized fatigue “Gelling” phenomenon
morning stiffness; difficult to resume motion
Extra-Articular Manifestations
20% of patients have rheumatoid nodules Carpel tunnel sydrome Synovial cysts Pleuropulmonary disease Systemic rheumatoid vasculitis
Laboratory Values
High elevation of rheumatoid factor (RF) Antinuclear antibody (ANA) detected in about 50% of patients Active phase: patients have elevated erythrocyte sedimentation rate (ESR) Some affected patients have mild anemia
Medical Management
NSAIDs Glucocorticoids Immunosuppression
Dental Management
AHA Guidelines Short dental appointments Assess if aspirin or NSAIDs are affecting platelet function
Sjogren’s Syndrome
Inflammation of the lacrimal and salivary glands
Incidence
0.2-3.0% of population More common in females 15% of patients with rheumatoid arthritis 30% of patients with SLE
Signs and Symptoms
Dry mouth, skin, eyes, nose and vagina Tongue becomes fissured and exhibits atrophy of the papillae Oral mucosa red and tender Parotid enlargement
Extra-glandular Signs and Symptoms
Lymphadenopathy Vasculitis Interstitial nephritis Interstitial lung fibrosis Primary biliary cirrhosis (PBC)
Raynaud’s phenomenon Peripheral neuropathies Scleroderma
Laboratory Values
High erythrocyte sedimentation rate and serum immunoglobulin levels (IgG) 75% of patients have RF regardless of rheumatoid arthritis Antinuclear antibodies (ANA) also present
Medical Management
Local manifestations can be treated symptomatically
Dental Management
Prevention of caries
daily use of fluoride, frequent recalls
Enhance salivary output
sugarless gum/candy, saliva substitutes (salivart, biotene, oral balance, mouth kote, glandosane, prescription medication (salagen, ` evoxac)
Treatment of oral candidiasis
antifungals
Pain control for enlarged salivary glands
Systemic Lupus Erythematosus
A chronic multisystem disease of unknown origin that exhibits wide variations in its clinical expression and disease course
Incidence
Females are affected 8-10 times more than men Average age is 31 years
Signs and Symptoms
Fever, weight loss, arthritis, fatigue, and general malaise Butterfly rash on the malar area and nose 40-50% of patients have affected kidneys
Cardiac involvement
-Libman-sacks endocarditis found in 50% of patients upon autopsy -pericarditis, myocarditis, endocarditis, CAD
Oral lesions
-5-25% of patients have affected palate, buccal mucosa, and gingiva
Laboratory Values
95% of patients have elevated ANA 70% of patient have antibodies directed against double-stranded DNA
Medical Management
Avoid excessive exposure to sunlight NSAIDS for mild active disease with antimalarial drugs Topical corticosteroids
Dental Management
AHA Guidelines Assess adrenal function for possible suppression Consult with physician regarding systemic manifestation Assess if NSAIDS are affecting platelet function
