Summary:A 59-year-old man with a 4-year history of light chain myeloma relapsing after two preceding autografts and salvage therapy with thalidomide underwent a peripheral blood stem cell (PBSC) transplant from his HLAidentical sister after conditioning with 100 mg/m 2 melphalan. Graft-versus-host disease (GVHD) prophylaxis comprised cyclosporine. Despite pulmonary infiltrates and sinusitis at the time of the allograft, it was decided to proceed with the transplant because the myeloma was refractory and rapidly progressive.
The association of pregnancy with acute renal failure, microangiopathic haemolytic anaemia and thrornbocytopenia is an unusual but well described event occurring typically in the postpartum period (Robson et al. 1968;Schoolwerth et al. 1976) and this may be recurrent (Gomperts et al. 1978). One patient has been described in the fifth month of pregnancy, in whom no improvement in renal function was observed after heparin therapy, and persistent malignant hypertension required bilateral nephrectomy (Vandewall et al. 1975). We record a similar case history occurring in the first trimester. Case reportA 25-year-old white primigravida was seen during the first trimester of pregnancy complaining of easy bruising, particularly on her legs. In the previous year menorrhagia had been managed on a mini-oestrogen contraceptive for 2 months. Six months before presentation she had married and was at that time asymptomatic. She had taken no medication in the 3 months before her presentation. having been fitted with an intrauterine contraceptive device instead. Her past history was not contributary; physical examination was normal.On examination the patient was pale with some bruises and scattered purpuric spots present over the lower extremities. Blood pressure was 120/70 mmHg and all pulses were present and equal. Initial haemoglobin was 9 . 2 g/dl, with normal erythrocyte indices but marked fragmentation present on the peripheral blood smear. Uncorrected reticulocyte count was 0306-5456/83/0600-0578%02.00 C 1983 British Journal of Obstetrics and Gynaecologj, 5 78 12.7% and ESR was 1 6 m m in 1 h. Total leucocyte count was 7.2x1OY/1 with a normal differential count and platelets 48x 10y/l. Bonemarrow examination showed a hypercellular marrow with normoblastic hyperplasia, normal granulopoiesis and megakaryocyte numbers. There was no iron demonstrable in marrow reticuloendothelial cells.Urine examination showed 2 + proteinuria with microscopic haernaturia. No casts or other abnormalities were present.Blood urea was 56 (normal 20-35) mg/ml, creatinine 1.6 (normal 0.5-0.8) mg/ml and creatinine clearance 73 (normal 86-1 10) ml/min. Lactic dehydrogenase and unconjugated bilirubin levels were raised, but the remainder of the biochemical profile was normal.Chest X-ray and electrocardiogram were normal. Haemoglobin electrophoresis, Coombs' test, serology for collagen-vascular disease, VDRL, Paul Bunnell and antiplatelet antibodies were all negative. Bleeding time was 15 (normal 2-8) min and platelet sizing showed increased megathrombocytes.Fibrinogen, fibrinogen degradation products, prothrombin time, reptilase time, partial thromboplastin time and thrombin time were normal. Screening tests for lymphocytotoxic antibodies were negative.In the the course of the next week the patient remained well, but falling haemoglobin and persisting erythrocyte fragmentation were cause for concern. With informed consent, the pregnancy was terminated by vacuum extraction followed by curettage. Despite this procedure there was a further fall in haemo...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
