Abstract: | Immune thrombocytopenia is a rare complication of progressive systemic sclerosis (PSS). A 47-year-old female with PSS treated with D-penicillamine developed immune thrombocytopenia, which promptly responded to prednisolone and withdrawal of D-penicillamine. Platelet-associated IgG was elevated and the bone marrow megakaryocyte count was normal. There was an inverse relationship between the level of platelet-associated IgG and the platelet count. A lymphocyte stimulation test sensitized by D-penicillamine was positive. The present case suggests that immune thrombocytopenia may be regarded as one of the D-penicillamine-related immune abnormalities. To our knowledge, its association with PSS has never been reported. |
