Maternal death during pregnancy, although uncommon, may result from a broad range of conditions. In this paper, a case of thrombotic thrombocytopenic purpura diagnosed by postmortem examination is presented. Thrombotic thrombocytopenic purpura is one of a subset of diseases that result in the formation of microthrombi within the vasculature, either as a primary or secondary manifestation. Other conditions included in the differential diagnosis during pregnancy are hemolytic uremic syndrome, systemic lupus erythematosus, preeclampsia-eclampsia and the HELLP syndrome, acute fatty liver of pregnancy, antiphospholipid antibody syndrome, and disseminated intravascular coagulation. The histologic manifestations of these diseases can be similar and in most cases do not provide adequate information to accurately differentiate these diseases in the postmortem period. This paper addresses the need for clinical history (i.e., symptomatology, trimester of onset) and antemortem laboratory testing in addition to a thorough autopsy to accurately differentiate among the conditions named previously. In the absence of an adequate clinical history and antemortem laboratory testing, the more general diagnosis of "thrombotic microangiopathy of pregnancy" is acceptable.

The thrombotic thrombocytopenic purpura syndrome (TTP) can be mistaken for a number of other conditions, and it is important to diagnose correctly and treat appropriately. We describe the features of TTP that can help make a positive diagnosis and other conditions in the differential diagnosis with symptoms that can overlap and mimic those of TTR. We discuss TTP and its variants, hemolytic uremic syndrome, disseminated intravascular coagulation, heparin-induced thrombocytopenia, antiphospholipid syndrome, Evans syndrome, preeclampsia/eclampsia, HELLP syndrome, acute fatty liver of pregnancy, and multiorgan failure.

The significance of antibodies to cardiolipin (anti-CL) remains uncertain in patients with chronic hepatitis C (CH-C). The main purpose of this study was to elucidate the clinical characteristics of patients with CH-C seropositive for anti-CL. The prevalence of anti-CL and clinical parameters associated with anti-CL in those patients were examined. Six of the 45 (13%) patients with CH-C had anti-CL. However, none of these six CH-C patients fulfilled the criteria for antiphospholipid syndrome. Serum triglyceride and apolipoprotein B (ApoB) levels in CH-C patients with anti-CL were significantly higher than those in CH-C patients without anti-CL. Serum triglyceride levels positively correlated with serum ApoB levels. CH-C patients with anti-CL had significantly more progressive hepatic fibrosis than those without anti-CL. The degree of 8-hydroxy 2'-deoxyguanosine (8-OHdG) expression in the liver tissue was more severe in CH-C patients with anti-CL than in those without it. However, the emergence of anti-CL in CH-C patients was independent of insulin resistance, hepatic steatosis, and iron overload. These findings suggest that the emergence of anti-CL is associated with oxidative stress and that CH-C patients seropositive for anti-CL have clinical characteristics of hypertriglyceridemia, which derives from the facilitation of ApoB synthesis, and progressive hepatic fibrosis.

HELLP syndrome is a collection of symptoms described as hemolysis, elevated liver enzymes and low platelets. HELLP syndrome complicates 0.01-0.6% of pregnancies and can be considered a severe variant of preeclampsia. The occurrence of HELLP syndrome diagnosed before the 20th week of gestation has been most commonly reported in association with antiphospholipid antibody syndrome (APS) or triploid chromosomal anomalies. A 41-year-old primigravida was admitted at 17 weeks and 6 days gestation with hypertension, proteinuria, hemolytic anemia and acute renal injury. She was diagnosed with HELLP syndrome, and subsequently suffered from an intrauterine fetal demise. After delivery, the clinical manifestations of HELLP syndrome resolved within 7 days with the exception of her acute renal failure. Interdisciplinary teams of physicians were able to exclude other imitators of preeclampsia, such as hemolytic uremic syndrome (HUS), thrombotic thrombocytopenic purpura (TTP), APS, lupus and acute fatty liver of pregnancy. This case is difficult to diagnose, given the similar presentation of several microangiopathic hemolytic anemias. The clinical manifestations and laboratory findings of HELLP and its mimicking conditions seem as if they are mirror images of each other. However, the discrete differences in our patient presentation, clinical findings, laboratory results and overall postpartum course leave HELLP syndrome as the most consistent diagnosis. It is imperative to investigate for all possible etiologies as HELLP syndrome at 17 weeks gestation is extremely rare and mimicking conditions may require alternative management strategies.

Pre-eclampsia complicated by severe HELLP (hemolysis, elevated liver enzymes and low platelet count) syndrome is a multi-organ disease, and can be difficult to differentiate from thrombotic microangiopathy (appearing as thrombotic thrombocytopenic purpura or hemolytic uremic syndrome), acute fatty liver, systemic erythematous lupus, antiphospholipid syndrome and severe sepsis. Many papers have highlighted the risks of misdiagnosis resulting in severe consequences for maternal health, and this can be fatal when thrombotic thrombocytopenic purpura is misdiagnosed as severe HELLP syndrome. The aim of this paper is to propose relevant markers to differentiate pre-eclampsia complicated by severe HELLP syndrome from its imitators, even in the worrying situation of apparently indistinguishable conditions, and thereby assist clinical decision-making regarding whether or not to commence plasma exchange. Relevant identifiers to establish the most accurate diagnosis include the frequency of each disease and anamnestic data. Frank hemolysis, need for dialysis, neurological involvement and absence of disseminated intravascular coagulation are indicative of thrombotic microangiopathy. The definitive marker for thrombotic thrombocytopenic purpura is undetectable ADAMTS 13 activity.

HELLP syndrome is a disorder associated with serious maternal morbidity and mortality. Distinguishing HELLP from other pregnancy-related disorders is often challenging and may result in delay of treatment. Differential diagnoses include acute fatty liver of pregnancy, thrombotic thrombocytopenic purpura, antiphospholipid syndrome, and hemolytic uremic syndrome, and are reviewed in this chapter. While there is not any current treatment for HELLP, the mainstay of treatment involves maternal stabilization and timely delivery. Various treatment strategies have been attempted to help decrease the morbidity and mortality of HELLP, including the maternal use of corticosteroids. The authors review the studies and controversies surrounding the maternal use of corticosteroids, plasma exchange, and low molecular weight heparin for the treatment of HELLP, as well as the role of the complement system in HELLP. Further large, well-designed, randomized controlled trials are needed to address the role corticosteroids may play in the treatment of women with HELLP and to help improve maternal and fetal outcomes.

Thrombocytopenia during pregnancy presents unique challenges for the hematologist. Obstetricians generally manage many of the pregnancy-specific etiologies, ranging from the benign (gestational thrombocytopenia) to the life-threatening (preeclampsia; hemolysis, elevated liver enzymes and low platelets syndrome; and acute fatty liver of pregnancy). However, hematologists may be consulted for atypical and severe presentations and to help manage non-pregnancy specific etiologies, including immune thrombocytopenia, thrombotic thrombocytopenic purpura, hemolytic uremic syndrome and antiphospholipid syndrome, among others, in which maternal and fetal risks must be considered. This review provides a general approach to the diagnosis and management of thrombocytopenia in pregnancy for the consulting hematologist.
