Refractory Thrombocytopenia in a 29-Year-Old Pregnant Woman With Autoimmune Hepatitis: A Case Report and Literature Review.

Autoimmune hepatitis (AIH) is a rare autoimmune liver disease that mostly affects women in their reproductive years, leading to impaired fertility. Nonetheless, the majority of women with well-controlled AIH have a favorable prognosis for pregnancy. This case report describes a 29-year-old pregnant woman with cirrhosis secondary to AIH who presented with severe thrombocytopenia. Her labs showed a decline in her platelet counts from 28 × 109/L before pregnancy to 20 × 109/L during pregnancy. Her abdominal ultrasound showed liver cirrhosis secondary to AIH and splenomegaly. Throughout pregnancy, various scans were performed to monitor the fetal well-being, which showed normal results. She was on a medication regimen that included nadolol of 80 mg/kg/day, prednisolone of 5 mg/kg/day, and azathioprine of 50 mg/kg/day. Due to a breech presentation, the patient was scheduled for a cesarean section. She received two courses of dexamethasone at 20 mg/day for four days within two weeks of delivery. On the day of her scheduled C-section, tranexamic acid of 1 g TID for two days was administered, and she received platelet transfusions of 12 units both before and after the procedure, with an additional 6 units administered during the procedure. Despite proper management, her platelet count remained consistently low. However, she successfully delivered a healthy baby, and the overall condition of the patient was stable.

Early HELLP Syndrome or Catastrophic Antiphospholipid Syndrome? A Diagnostic Dilemma.

Hypertensive disorders of pregnancy typically occur in the third trimester, with earlier presentations associated with underlying disorders such as antiphospholipid syndrome (APLS). We describe a case of a young primigravida presenting at 15 weeks 6 days gestation with epigastric pain, vomiting, new-onset severe-range hypertension, and subsequent development of anemia, thrombocytopenia, and transaminitis. Antiphospholipid antibodies (aPL) were triple-positive and imaging was negative for thrombosis. She was treated with aspirin, therapeutic anticoagulation, and ultimately dilatation and evacuation with initial postoperative improvement. Her symptoms returned postoperative day 3 and resolved following re-initiation of therapeutic anticoagulation. The differential diagnosis for hypertensive disorders of pregnancy is wide, particularly in second-trimester gestation, and includes catastrophic antiphospholipid syndrome (CAPS), lupus flare, microangiopathic anemias, and acute fatty liver of pregnancy. This case was an atypical presentation not clearly explained by any of the above diagnoses and required a multidisciplinary approach. Obstetric patients with high-risk aPL must be meticulously investigated with a broad differential to guide diagnosis and treatment.

Hematologic Findings in Pregnancy: A Guide for the Internist.

Hematologic changes in pregnancy are common and can potentially lead to maternal and fetal morbidity. Here, we present various hematologic manifestations seen in pregnant women. Iron deficiency anemia (IDA) is the most common cause of anemia in pregnancy. Physiologically, the state of pregnancy results in increased iron demand. Iron deficiency is important to diagnose and treat early for better maternal and fetal outcomes. An algorithmic approach is used for the repletion of iron storage, starting with oral elemental iron daily and escalating to intravenous iron if necessary. Folate and cobalamin are necessary elements for deoxyribonucleic acid (DNA) synthesis, fetal growth, and maternal tissue development, and deficiency in these elements can be a cause for anemia in pregnancy. Thrombocytopenia is currently the second most common hematologic condition in pregnancy after anemia. There is a wide range of etiology for thrombocytopenia in pregnancy from benign to life-threatening causes that require prompt diagnosis and treatment. These conditions include gestational thrombocytopenia, thrombotic thrombocytopenic purpura, pregnancy-associated atypical hemolytic-uremic syndrome, and immune thrombocytopenia. Acquired bleeding disorders that can cause major complications in pregnancy include von Willebrand disease (vWD) and coagulation factor deficiencies. Women with vWD are at increased risk of pregnancy bleeding and postpartum hemorrhage. Pregnancy can also produce a physiologic hypercoagulable state, leading to life-threatening conditions like thromboembolism. Diagnosis, treatment options, and guidelines for the management of these conditions will be explored in this review.

Thrombocytopenia in Pregnancy Nearing Term: A Clinical Analysis.

BACKGROUND AND AIM: Thrombocytopenia in pregnancy varies from benign to severe with fetomaternal complications. We aimed to evaluate thrombocytopenia in pregnant Indian females in third trimester mainly during labor and delivery. MATERIALS AND METHODS: It was a prospective observational study done in a tertiary care teaching public hospital over 1 year. Consecutive 150 pregnant patients admitted to labor ward with thrombocytopenia were analyzed for etiology of thrombocytopenia, severity, mode of delivery, type of anesthesia, and fetomaternal complications. SPSS version 17 was used for the analysis. RESULTS: Most common cause of thrombocytopenia was preeclampsia 50 (33.3%) and preeclampsia with hemolysis, elevated liver enzyme, and low platelet count syndrome (HELLP syndrome) 31 (20.7%) together followed by gestational 42 (28%). Infectious causes such as malaria, dengue, and leptospirosis were found in 19 patients (12.7%). Moderate to severe thrombocytopenia was seen in preeclampsia, preeclampsia with HELLP syndrome, and infectious etiology. Eleven patients (7.3%) developed antepartum hemorrhage (APH), 24 (16%) postpartum hemorrhage (PPH), 12 (8%) required ICU admission, and 3 (2%) mortalities were noted. Fifteen neonates (10%) needed ICU admission. Complications were observed in preeclampsia with HELLP syndrome (82%) and infectious causes (18%) and none in gestational. Sixty-eight patients underwent lower segment cesarean section (LSCS), among them 41 (27.3%) were given spinal anesthesia (SA) and none of them developed any neurological complications. CONCLUSION: Study widened the spectrum of causes for thrombocytopenia in pregnant patients. Preeclampsia with or without HELLP syndrome and vector-borne infections such as malaria, dengue, and leptospirosis were found to be very important causes of moderate to severe thrombocytopenia and were associated with complications. Spinal anesthesia is safe in parturients with mild thrombocytopenia. Awareness and vigilance about thrombocytopenia is vital to reduce maternal morbidity and mortality.

Effect of recombinant human thrombopoietin on immune thrombocytopenia in pregnancy in a murine model.

Primary immune thrombocytopenia (ITP) is a serious medical disorder that has the potential for maternal and fetal mortality. Corticosteroids, intravenous immunoglobulin, or both are the first-line treatments for ITP in pregnancy, but choices are limited if patients fail to respond. Recombinant human thrombopoietin (rhTPO) has been proved effective and safe in management of chronic ITP. However, the efficacy and safety of rhTPO for pregnant ITP patients still need to be explored. Here we developed an ideal murine model that simulated human ITP in pregnancy and evaluated the efficacy and safety of rhTPO in management of ITP in pregnancy. Model mice were subcutaneously administered with 0, 150, 1,500 and 15,000 U/kg rhTPO for 14 days. Significant higher platelet counts were noted in rhTPO-treated groups on Day 7, 10 and 14. On Day 20, half the maternal mice were sacrificed. Frequencies of Tregs in CD4+ T cells in rhTPO-treated groups were statistically higher than control. Significant higher plasma levels of TGF-ß1 were observed in rhTPO-treated groups than control. There was no significant abnormality in gross or visceral examination of fetuses. The remaining half maternal mice and their pups were observed for at least three weeks to assess vital signs. No abnormal signs were noted. Furthermore, we investigated the underlying mechanisms. Results showed that Tregs were negative for c-Mpl and rhTPO had no direct effect on Tregs. Additionally, the Treg frequency in splenic CD4+ T cells in LY2109761-treated model mice was statistically lower than control. Thus, rhTPO may be a safe and effective option for treatment of pregnant ITP patients.

Reproductive and developmental toxicity study of caffeic acid in mice.

Caffeic acid is an antioxidant commonly used to promote hematopoiesis and hemostasis. However, little is known about its systemic safety profile in reproduction and development. Here, we focused on the reproductive and developmental toxicity of caffeic acid in F0 female mice and F1 offspring. In the three-segment study, the F0 female mice were continuously exposed to 0, 0.15, 5 or 150 mg/kg/day of caffeic acid by gavage. We found that 5 mg/kg/day and 150 mg/kg/day of caffeic acid affected implantation of embryos when administered before gestation day 6. In addition, 150 mg/kg/day of caffeic acid affected fetal weight gain. No maternal toxicity, fetal teratogenesis or post-natal effects on pup development were observed. The no-observed-adverse-effect-level was 0.15 mg/kg/day for pregnant mice under the conditions of this study.

Diagnostic dilemma: Severe thrombotic microangiopathy in pregnancy.

A diagnostic dilemma occurred when thrombotic microangiopathy developed during pregnancy. The diagnostic criteria of thrombotic microangiopathy include thrombocytopenia (platelets <100) and microangiopathic haemolytic anaemia (including thrombotic thrombocytopenic purpura and haemolytic-uraemic syndrome). An urgent interdisciplinary approach is required to treat thrombotic microangiopathy in pregnancy to differentiate between thrombotic microangiopathy and HELLP syndrome (haemolysis, elevated liver enzymes, low platelets).1 This case presented with the pentad of thrombotic thrombocytopenic purpura: severe thrombocytopenia (platelets 9 × 109/L), microangiopathic haemolytic anaemia (reticular count 245 × 109/L (20-110)), LDH >5000 U/L (<425)), neurological abnormalities (Glasgow Coma Scale 10/15), renal failure (creatinine 140 µmol/L (<97)), fever (37.7℃). A Disintegrin And Metalloproteinase with a Thrombospondin type 1 motif, member 13 (ADAMTS13) activity of less than 5% and anti-ADAMTS13 antibodies retrospectively confirmed the diagnosis of acquired idiopathic thrombotic thrombocytopenic purpura in pregnancy. The immediate management in the Emergency Department with an interdisciplinary team of Consultant Nephrologists, Intensivists, Haematologists and Obstetricians facilitated prompt diagnosis resulting in immediate plasma exchange (PEX) and coordination of semi-elective delivery of the foetus.

Successful Vaginal Delivery Following Immunologic Thrombocytopenic Purpuric Woman: Case Report With Prior History / 대한산부인과학회잡지

Thrombocytopenia is hematologic disorder commonly occurs during pregnancy (5%) with different severity. It doesn't cause severe problem during pregnancy and after the delivery if it is not below certain level which will cause spontaneous bleeding. But in this case, patient was previous cesarean section status and platelet number didn't arise more than 20,000/microliter even after transfusion which will cause spontaneous bleeding. Vaginal delivery was done because transverse cesarean section was considered relatively safe although there was the risk of rupture of uterus, and was successful-both mother and baby is in good health condition. Here now we report this case because vaginal delivery of Immunologic thrombocytopenic purpuric woman with prior history of cesarean section has not reported.
