Omalizumab effects rapid, often complete, clearance of refractory bullous pemphigoid
AT AAD 17
• A 78-year-old woman with refractory BP of 1.5 years responded well to three initial injections spaced 6 and 4 weeks apart, and has been well maintained for 20 months with 300-mL injections administered once a month. One relapse was easily controlled.
• A 72-year-old woman with 3.5 years of refractory BP responded well to 375 mg injections every 4 weeks and has been symptom free for a year on that maintenance dose.
• A 55-year-old woman with a 7-month history of refractory BP experienced a 30% reduction in body surface area blistering within 1 week of her first 375-mg injection. By 3 weeks, she was clear. She had three injections, 2 weeks apart, and was disease free for 3 months.
• An 86-year-old woman with longstanding refractory BP experienced a 22% reduction in blister count within a week of her first 375-mL injection. After a series of injections every 2 weeks, however, she developed an exacerbation of her preexisting chronic obstructive pulmonary disease, which was due primarily to tapering her prednisone. However, she no longer uses omalizumab.
“It is difficult to make recommendations because of the limitations of our data,” Dr. Yu said. “But based on the small number of patients we have treated, I would consider using omalizumab in patients with resistant disease who have an elevated IgE and eosinophil count. The optimal dosing regimen is not yet determined. Our approach is to start out with the asthma dosing and titrate until we see improvement. We use the highest dose indicated for the patient’s weight and IgE levels, typically 300-375 mg subcutaneously every 2-8 weeks, and start tapering when the patient gets control.”
