BACKGROUND:
Intramuscular human immunoglobulin (HIG) may provide a therapeutic option as an independent or combined treatment for recalcitrant suppurative skin diseases such as hidradenitis suppurativa, folliculitis decalvans, or chronic recurrent furunculosis or folliculitis.
OBJECTIVES:
To define the efficacy and safety of intramuscular HIG for chronic and recalcitrant suppurative skin diseases.
METHODS:
Patients who had received HIG for hidradenitis suppurativa, folliculitis decalvans, furunculosis or folliculitis at Severance Hospital, Seoul, Korea, between January 2000 and May 2005 were identified from medical/pharmacy records. All records were analysed retrospectively.
RESULTS:
Sixty-three patients were identified. After treatment, 37 patients (59%) showed overall improvement and were rated as having an 'excellent response' or 'good response' by the attending physician. No improvement or worsening was seen in only three patients (5%). A period without new lesions (PWNL) was achieved in 46 patients (73%). The number of times HIG was administered to achieve PWNL ranged from 1 to 12 (mean +/- SD 2.15 +/- 1.69). There was no significant difference in the rating score between the independent intramuscular HIG and the combined treatment groups. Pain at the injection site was the major side-effect, which led to the discontinuation of treatment in five patients. No other significant systemic side-effects were observed.
CONCLUSIONS:
Our results demonstrate that intramuscular HIG may be used for the treatment of recalcitrant suppurative skin diseases as an independent or combined treatment.
