title: Plasma cell leukaemia and HIV co-infection: profile of patients and experience at Universitas Academic Hospital in Bloemfontein, South Africa.
abstract: Plasma cell leukaemia (PCL) is a rare condition with high mortality. HIV-positive patients have a propensity to develop malignancy; however, the occurrence of PCL with HIV infection in South Africa has not been documented. We describe patients with PCL in Universitas Hospital in Bloemfontein, South Africa, and report two new cases of HIV infection concurrent with PCL. A retrospective case series of PCL patients (2006-2012) seen at our Clinical Haematology unit is reported. Patient files were used to obtain information. The median age of patients (n = 9) was 51 years, and 66.7 % of cases were of African ethnicity. The condition was equally distributed between genders. Two patients were HIV positive. Both received combination antiretroviral therapy. The diagnosis of PCL was usually made as an incidental finding, subsequently confirmed on bone marrow aspirate and trephine. Deranged haematological and biochemical parameters, including severe anaemia, hypoalbuminaemia, and hyper-cellular bone marrow, were observed. Only one patient improved markedly on treatment, and remains alive at the time of writing. PCL shows poor response to treatment and predominates among Africans. The small sample size made it difficult to determine whether co-infection with HIV was a coincidental finding or the two diseases are pathophysiologically linked.
