SummaryA combination of clarithromycin, low dose of thalidomide and low dose dexamethasone was used in a phase II study to treat patients with relapsed and refractory myeloma. Thirty patients received clarithromycin 250 mg twice daily and thalidomide 50 mg at night on an ongoing basis with 4-d pulses of 10 mg dexamethasone given monthly. Eight patients had permitted escalation of thalidomide dosage up to 200 mg daily. The combination was well tolerated and could be given to elderly, infirm and severely cytopenic patients. Response rates were high, with 89% achieving at least 50% reduction in paraprotein and a 96% overall response rate. Although clarithromycin has only minimal anti-myeloma properties when used as a single agent, its combination with thalidomide and dexamethasone appears very effective, allowing these to be used in lower and more tolerable doses with good clinical effects.

The sclerodermatous variant of chronic graft-versus-host disease postallogeneic bone marrow transplantation is rare. We present four pediatric cases of sclerodermatous variant of chronic graft-versus-host disease describing their clinical appearance, management, and outcomes. We compare the pharmacologic and supportive therapies administered to these patients with the management suggested in the current literature. Several key findings were noted. There was a significantly higher mortality rate observed in this series compared with previous reports, with three of the four patients dying ultimately as a result of sclerodermatous variant of chronic graft-versus-host disease. The development of widespread ulceration, in two of the four patients, appeared to be associated with an overall deterioration in the clinical condition. In two patients high-dose thalidomide at 12 mg/kg/day seemed to halt the progression of cutaneous disease. Optimal care of sclerodermatous variant of chronic graft-versus-host disease patients required a multidisciplinary team. A lack of community services observed in this case series led to the need for unnecessarily prolonged inpatient admissions.
