Treatment
Medical Care
Medical treatment is specific for the disease entity. Some common examples follow.
- Contact dermatitis: The treatment of contact dermatitis varies depending on the severity of the disease. The best advice is to avoid the offending antigen. Pharmaceutical treatment varies, including over-the-counter corticosteroid preparations, prescription corticosteroid preparations, injectable corticosteroids, oral corticosteroids, and Burow solution.
- Tuberculin hypersensitivity skin reactions: Treatment is rarely needed because this response is usually short-lived and self-limited. Topical corticosteroid preparations can be applied as needed. On rare occasions, the reaction to a delayed hypersensitivity skin test may be extreme and result in axillary lymphadenopathy and fever. Such reactions are self-limited and may be treated with an antipyretic medication such as aspirin or ibuprofen.
- Granulomatous diseases: Treatment varies greatly depending on the specific disease. Refer to the appropriate eMedicine article for a full discussion (eg, see Sarcoidosis or Crohn Disease).
Consultations
Whether or not to consult a specialist and which specialist to consult also depend on the specific disease and its severity.
- Contact dermatitis: Most cases of contact dermatitis can be managed in an outpatient setting by a primary care physician. However, for severe cases, immediate consultation with a physician board-certified in allergy and immunology and/or dermatology is warranted.
- Tuberculin hypersensitivity skin reactions: If the Mantoux reaction is positive, patients may require consultation with a pulmonologist or an infectious disease specialist. A primary care physician trained in assessing the significance of a positive Mantoux reaction can also effectively treat these patients.
- Granulomatous diseases: Depending on the specific disease entity, an infectious disease specialist (eg, TB, fungal disease, schistosomiasis), pulmonologist (eg, TB, sarcoidosis), gastroenterologist (eg, granulomatous hepatitis, Crohn disease), and/or an allergist/clinical immunologist may need to be consulted.
Activity
As tolerated
Medication
Medical treatment differs greatly depending on the specific disease entity. Only a few medications are discussed. In addition to drugs mentioned below, a drug that may augment cell-mediated immunity is cimetidine, which is an H2 receptor blocker that acts as a reverse antagonist and may augment cell-mediated immunity.6
Corticosteroids
Have anti-inflammatory properties and cause profound and varied metabolic effects. Modify the body's immune response to diverse stimuli.
Triamcinolone (Aristocort)
Helps treat inflammatory dermatosis responsive to steroids. Decreases inflammation by suppressing migration of PMN leukocytes and reversing capillary permeability.
Adult
Topical: Apply a thin film bid/tid until a favorable response is obtained; not for use >3 consecutive wk
Alternatively, 40-80 mg IM once
Strength of dose should be individualized for patient
Pediatric
Administer as in adults; not for use >2 consecutive wk
None reported
Documented hypersensitivity; fungal, viral, or bacterial skin infections
Pregnancy
C - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
Precautions
Do not use in patients with decreased skin circulation; avoid using on face, neck, axillae, and groin; prolonged use, applications over large areas, and use of potent steroids and occlusive dressings may cause systemic absorption; systemic absorption may cause Cushing syndrome, reversible HPA axis suppression, hyperglycemia, and glycosuria
Mometasone (Elocon)
May depress formation, release, and activity of endogenous chemical mediators of inflammation.
Adult
Apply sparingly to affected areas bid; do not use occlusive dressing; usually, do not use >2 consecutive wk
Pediatric
Not recommended but frequently used for short periods
None reported
Documented hypersensitivity; fungal, viral, or tubercular skin lesions; herpes simplex or zoster infections
Pregnancy
C - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
Precautions
If used over large or denuded areas of body, for prolonged periods, with occlusive dressings, or in infants, adverse systemic effects may result
Prednisone (Deltasone, Orasone, Meticorten, Sterapred)
May decrease inflammation by reversing increased capillary permeability and suppressing PMN activity.
Adult
5-60 mg/d PO qd or divided bid/qid; taper over 2 wk as symptoms resolve
Pediatric
4-5 mg/m2/d PO; alternatively, 0.05-2 mg/kg PO divided bid/qid; taper over 2 wk as symptoms resolve
Coadministration with estrogens may decrease clearance; concurrent use with digoxin may cause digitalis toxicity secondary to hypokalemia; phenobarbital, phenytoin, and rifampin may increase metabolism of glucocorticoids (consider increasing maintenance dose); monitor for hypokalemia with coadministration of diuretics
Documented hypersensitivity; viral infection; peptic ulcer disease; hepatic dysfunction; connective tissue infections; fungal or tubercular skin infections; GI disease
Pregnancy
B - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
Precautions
Abrupt discontinuation of glucocorticoids may cause adrenal crisis; hyperglycemia, edema, osteonecrosis, myopathy, peptic ulcer disease, hypokalemia, osteoporosis, euphoria, psychosis, myasthenia gravis, growth suppression, and infections may occur
