ABSTRACT

Autosomal-recessive hyper-IgE syndrome (AR-HIES) is a combined immunodeficiency recently found to be associated with mutations of DOCK8. Clinically, this disorder is characterized beside recurrent bacterial complications, in particular by an unusual susceptibility to extensive cutaneous viral complications and by a high risk for squamous cell carcinoma. Here, we report on lasting control over the disorder in two patients by hematopoietic cell transplantation (HCT). Both patients were suffering from extensive long-lasting cutaneous viral complications, in particular from disfiguring molluscum contagiosum infections, when treated at the age of 10 and 17 years. Donors were matched unrelated, and conditioning was carried out with a combination of fludarabine, melphalan and BM-targeted radioimmunotherapy. Both patients developed stable, full donor cell chimerism, with the exception of persistent low-IgA serum levels and the exception of normal immune functions. Over the course of several months, cutaneous manifestations of viral disease resolved completely and both patients remain clinically well and free of infectious complications at 4 and 2 years, respectively, after transplantation. This represents the first report indicating HCT to be curative in patients with AR-HIES, which should be considered early before life-threatening complications develop, which include malignancies.

ABSTRACT

We report on 12 patients with chronic granulomatous disease transplanted with hematopoietic stem cells from matched unrelated (n = 9) or matched sibling donors (n = 3). The most common infectious complication was pulmonary aspergillosis, which nine patients had previously developed. Only 5 of 12 individuals had normal lung function prior to transplantation. At a mean follow-up of 53 months 9 of the 12 patients are alive including 7 of 9 following matched unrelated donor (MUD) transplantation. One patient died from ARDS, another from systemic BK virus infection, the third from complications of chronic graft-versus-host disease. Seven of nine surviving patients have normal lung function now. HSCT from a MUD is an option worth considering when no matched family donor is available. Restricted lung function prior to HSCT does not appear to be a limiting factor for such treatment.
