title: Direct-antiglobulin-test-negative immune haemolytic anaemia and thrombocytopenia in a patient with Hodgkin's disease.
abstract: A case of direct-antiglobulin-test (DAT)-negative auto-immune haemolytic anaemia (AIHA) and immune thrombocytopenia (ITP) associated with Hodgkin's disease (HD) is reported. A 52-year-old male was admitted with anaemia, thrombocytopenia, and lymphadenopathy. The patient was DAT negative, although he exhibited the clinical features of warm-type AIHA and elevated levels of red-blood-cell-associated IgG (RBC-IgG). The serum level of platelet-associated IgG (PA-IgG) was markedly increased. A biopsy specimen of the inguinal lymph nodes showed HD of mixed cellularity. Marked improvement of subjective symptoms, normalization of haematological values and a decrease in the level of both RBC- and PA-IgG were observed after the start of combination chemotherapy for HD. Although the association of HD, ITP, and/or AIHA has been infrequently reported, the measurement of RBC-IgG is recommended in cases of HD with anaemia even though DAT is negative, since HD is known to be associated with various protean immunological abnormalities.
