A 26-year-old female was referred to our hospital in the 20th week of a second pregnancy because of severe intra-uterine growth restriction, hypertension, thrombocytopenia and proteinuria. Working diagnosis was thrombotic thrombocytopenic purpura, but it was difficult to differentiate it from haemolysis, elevated liver enzymes, and low platelet count. Therapeutic plasma exchange was urgently initiated and pregnancy was terminated with prostaglandin induction. The activity level of ADAMTS13 (a disintegrin and metalloproteinase with trombospondin type-1 motifs 13, the von Willebrand Factor cleaving protease), was immeasurably low. Furthermore, the patient was positive for ADAMTS13 inhibitor, which confirmed a diagnosis of acquired thrombotic thrombocytopenic purpura.

The sub-committee on lymphoproliferative disorders of the Belgian Hematological Society has met several times to prepare guidelines on the management of patients with peripheral T-cell lymphomas. Each panellist’s expert provided interpretation of the evidence, based on literature review and personal experience. The available evidence was systematically discussed prior to formulating recommendations. A systematic approach to obtain consensus of expert opinion was used. After each meeting, the draft guideline was circulated to all experts for comment and approval. The present guidelines focus on general management of peripheral T-cell lymphomas with special emphasis on more specific disease-adapted strategies.

The guidelines for adult patients in this article are based on 2011 ESMO and NCCN version 4.2011 guidelines and amended for the particular Belgian context of label prescription and reimbursement. Levels of evidence for the use of treatment recommendations are given in square brackets. Statements without grading were considered justifed standard clinical practice by the experts of the BHS-lymphoma working party.

Thrombotic microangiopathy (TMA) can be a key feature of several pregnancy related disorders such as thrombotic thrombocytopenic purpura (TTP ) / Haemolytic uremic syndrome (HUS), congenital TTP(CTTP), HELLP syndrome, or acute fatty liver (AFL). TMA is a life threatening condition in pregnancy. It encompasses a spectrum of different disorders with a similar pathogenesis, but in most of the cases completely different therapy. It can take several days to obtain the diagnosis, and in case of doubt therapeutic plasma exchange (TPE) (plasmapheresis with plasma substitution) should be started immediately to ensure better outcome. By measuring the activity of the von Willebrand-factor-cleaving protease (ADAMTS13), it may be possible to distinguish between the different causes of thrombotic microangiopathy. Pregnancy-related TMA can occur before or after birth. A Pregnancy-related TMA that develops during the puerperium, typically develops about the fourth day postpartum. No other significant differences are seen between antepartum and postpartum pregnancy related TMA. In critically ill patients it may be difficult to distinguish TMA from sepsis with disseminated intravascular coagulation (DIC). DIC is generally associated with prolongation of global clotting times, prothrombin time and activated partial thromboplastin time (PTT, aPTT) due to consumption of clotting factors. TMA occurs by primary activation of platelets (congenital or acquired abnormalities of ADAMTS13), and by primary endothelial injury (as with HELLP syndrome). Antepartum pregnancy-related TMA usually occurs at 28 ± 8 weeks of pregnancy.
