The use of chlorambucil with prednisone in the treatment of pemphigus.

BACKGROUND: Chlorambucil is an alkylating agent that preferentially affects B cells over T cells and has been shown to be effective in the treatment of bullous pemphigoid. OBJECTIVE: Our purpose was to determine whether chlorambucil is effective in the treatment of pemphigus. METHODS: We retrospectively reviewed the medical records of 9 patients with pemphigus (7 with pemphigus vulgaris and 2 with pemphigus foliaceus) in whom therapy with other immunosuppressive regimens failed and who were subsequently treated with chlorambucil and prednisone. RESULTS: There was clinical improvement in 6 of 9 patients and a decrease in indirect immunofluoresent antibody titers in 3 of the 5 patients who had titers drawn before and after treatment with chlorambucil. Three of the 9 patients failed treatment with chlorambucil, as evidenced by lack of improvement of lesions. CONCLUSION: Chlorambucil may be a potential adjuvant therapeutic approach with steroid-sparing effects in patients with pemphigus who have failed treatment with other immunosuppressive regimens.

Behavior of tissue-engineered skin: a comparison of a living skin equivalent, autograft, and occlusive dressing in human donor sites.

OBJECTIVE: To compare the behavior of a tissue-engineered living skin equivalent (LSE) with an autograft in acute donor site wounds. DESIGN: Paired-comparison, randomized control trial. SETTING: A university dermatology service. PATIENTS: Three donor sites were created on the anterior thigh of each of 20 patients requiring split-thickness skin grafts. INTERVENTION: For each patient, the donor sites were randomly assigned to be treated with meshed LSE, meshed autograft, or a polyurethane film (PUF) occlusive dressing. Blood and biopsy samples were taken for immunologic and histological studies. MAIN OUTCOME MEASURES: Toxic effects or clinically apparent rejection, humoral and cellular immune responses, clinical take, healing time, pain, and 1-month histological appearance. RESULTS: There was no toxic effect or clinically apparent rejection of LSE. Results of humoral and cellular studies were unchanged from baseline. The average time to healing for LSE with clinical take was 7.3 days (SD, +/- 0.8 days); for autograft, 7.6 days (SD, +/- 1.1 days); and for PUF, 9.5 days (SD, +/- 1.8 days). The difference between LSE or autograft and PUF was statistically significant at the .001 level. Pain was experienced by 1 patient, no patients, and 10 patients at the LSE, autograft, and PUF sites, respectively. Histologically, LSE had the thickest epidermis (P = .02), PUF had the greatest degree of fibrosis (P = .02), and autograft had the least degree of increased inflammation (P = .004) and vascularity (P = .01). CONCLUSIONS: In acute donor site wounds, LSE appeared to clinically take and to be a safe and usable form of tissue therapy.

The treatment of bovine collagen allergy with cyclosporin.

BACKGROUND: Bovine collagen is currently the most common substance used in soft-tissue augmentation. Although patients should undergo routine skin testing for allergy to bovine collagen prior to treatment, hypersensitivity reactions may rarely still occur. Previously, there have been no reliable methods of treatment for these reactions, and physicians could only reassure patients that the reaction would slowly disappear. OBJECTIVE. The use of oral cyclosporin in a patient with hypersensitivity to bovine collagen was evaluated. METHODS: A patient with an allergic reaction to implanted bovine collagen was started on cyclosporin 175 mg p.o. bid (5 mg/kg/day) after no improvement was seen after treatment with oral and topical steroids. The cyclosporin was started on Day 23 of the allergic reaction. RESULTS: Improvement in the itching and redness was noted by Day 28 of the allergic reaction, and complete clinical resolution of the allergic reaction was noted on Day 41. On Day 47, the cyclosporin was stopped without recurrence of symptoms. The patient did not experience side effects from cyclosporin, and her blood pressure and renal function remained normal. CONCLUSION: This case report shows that oral cyclosporin A may be a safe and effective treatment for bovine collagen hypersensitivity.

Antimalarial agents and the eye.

Antimalarial compounds have been demonstrated to be both safe and efficacious in the treatment of lupus erythematosus as well as several other dermatologic conditions. It is imperative, however, that physicians familiarize themselves with the potential complications associated with the use of these agents. Furthermore, it is essential that a successful collaborative relationship be developed between the dermatologist and the ophthalmologist who are to treat and monitor the patient to avoid any untoward complications that might afflict the patient. It is important to stress that patients on antimalarial drug therapy be evaluated by an ophthalmologist prior to starting treatment and every 4 to 6 months thereafter. The use of Amsler's grids in compliant patients is recommended. If the patient develops retinal changes consistent with the diagnosis of premaculopathy, then careful consideration should be given to the availability and use of alternative agents.
