Bullous Systemic Lupus Erythematosus (BSLE) Medication
- Author: Ivan D Camacho, MD; Chief Editor: Dirk M Elston, MD more...
Medication Summary
Bullous systemic lupus erythematosus generally responds well to medical therapy. Dapsone represents the mainstay of treatment, typically leading to rapid clearance of lesions.
As in drug-induced toxic epidermal necrolysis, intravenous immunoglobulin represents an important therapeutic option for the Fas-mediated massive epidermal necrosis of fulminant toxic epidermal necrolysis–like lupus erythematosus.
Antimycobacterial Agents
Class Summary
Therapy must be comprehensive and should cover all likely pathogens in the context of the clinical setting.
Dapsone
The general mechanism of action of dapsone is similar to that of sulfonamides, in which competitive antagonism of para-aminobenzoic acid (PABA) prevents the formation of folic acid, inhibiting bacterial growth.
The anti-inflammatory mechanism of dapsone is believed to result from suppression of neutrophils by the inhibition of neutrophil myeloperoxidase and inflammation-inducing oxygen intermediates. Dapsone has been shown to inhibit some forms of neutrophil chemotaxis, suppress leukocyte integrin function, and decrease the attachment of neutrophils to endothelial cell junctions.
Corticosteroids
Class Summary
These agents have anti-inflammatory properties and cause profound and varied metabolic effects. Corticosteroids modify the body's immune response to diverse stimuli.
Prednisone
Prednisone decreases inflammation; in particular, it suppresses neutrophil presence and activity at sites of inflammation by inhibition of endothelial cell adhesion molecule expression and chemoattractant production. Prednisone also inhibits antigen presentation, T lymphocyte activity, and (at higher doses) antibody production.
Immunosuppressive Agents
Class Summary
These drugs have anti-inflammatory effects.
Methotrexate (Trexall, Rheumatrex)
Methotrexate is an antimetabolite that inhibits dihydrofolate reductase, thereby hindering deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) synthesis in lymphocytes and other immune cells. Anti-inflammatory effects also result from the inhibition of 5-aminoimidazole-4-carboxamide ribonucleotide (AICAR) transformylase (increasing tissue concentrations of the anti-inflammatory mediator adenosine) and methionine synthetase (reducing production of the proinflammatory mediator S-adenyl methionine).
Azathioprine (Imuran, Azasan)
Azathioprine antagonizes purine metabolism and inhibits the synthesis of DNA, ribonucleic acid (RNA), and proteins. It may decrease the proliferation of immune cells, in that way lowering autoimmune activity.
Mycophenolate mofetil (CellCept) or mycophenolic acid (Myfortic)
Mycophenolate mofetil has been shown to useful in the treatment of autoimmune diseases.
Blood Products
Class Summary
These are used to improve the clinical and immunologic aspects of the disease. They may decrease autoantibody production and increase solubilization and removal of immune complexes.
Immune globulin intravenous (Gamunex, Octagam, Gammaplex , Gammagard)
This provides an antibody-mediated blockade of Fas-Fas ligand interactions involved in the epidermal necrosis of toxic epidermal necrolysis–like cutaneous lupus erythematosus.
