Alpha-methyldopa-induced immune thrombocytopenia. Report of case.
ABSTRACT The clinical and laboratory features of a case of alphamethyldopa-induced thrombocytopenia are described. This is the second reported case in which the presence of alpha-methyldopa-induced platelet antibodies have been demonstrated.

ABSTRACT: A variety of drugs may cause thrombocytopenia. Although it occurs more often than drug-induced anemia it is less well understood because techniques for studying drug-platelet-immune interactions have been unavailable until recently. The mechanisms by which drugs cause thrombocytopenia are varied. Bone marrow suppression or increased peripheral destruction of platelets could be involved. Nonimmunologic as well as immunologic mechanisms may also occur. These different mechanisms of drug-induced thrombocytopenia are reviewed. Diagnostic methods and treatment are also summarized.Veterinary Research Communications 02/1986; 10(1):1-20. DOI:10.1007/BF02213961 · 1.36 Impact Factor

ABSTRACT: An inhibitor to the plasma coagulation factor VIII and abnormally high levels of platelet associated IgG (PAIgG) were found in a patient whilst on methyldopa. Both these parameters fell on initial withdrawal, but on rechallenge with the drug only the PAIgG rose to the high presenting levels. No inhibitory activity to factor VIIIc could be detected in a concentrated eluate prepared from the patient's platelets. These results may imply that two distinct antibodies were provoked by the administration of methyldopa, but could also be explained by the action of anti VIIIc alone on the patient's platelets.British Journal of Haematology 08/1983; 54(3):485-8.
