Anesthetic management for cesarean delivery in a parturient with exacerbated hemophagocytic syndrome

Hemophagocytic lymphohistiocytosis in pregnancy evolving towards fulminant hepatitis

Background

Hemophagocytic lymphohistiocytosis is a rare disorder, especially in pregnancy, characterized by excessive immune activation leading to hemophagocytic activity.

Case Report

A 34-year-old woman presented at 31 weeks' gestation with fever, cytopenias, hyperferritinemia and fulminant hepatitis. Bone marrow biopsy was non-contributory, and no trigger was identified. Liver biopsy confirmed the diagnosis of hemophagocytic lymphohistiocytosis, and she received dexamethasone and etoposide, which was changed to anakinra to allow breastfeeding. Prompt diagnosis and treatment of hemophagocytic lymphohistiocytosis is crucial to the survival of pregnant women, but no consensus exists regarding the most appropriate therapy during pregnancy.

Conclusion

Hemophagocytic lymphohistiocytosis is life-threatening and associated with significant morbidity and mortality. Important treatment considerations in pregnancy include maternal health, fetal prematurity and treatment toxicity. Anakinra has been successfully used in pregnancy and provides a promising alternative.

Haemophagocytic lymphohistiocytosis during pregnancy: a case presentation and literature review

Objectives

Haemophagocytic lymphohistiocytosis (HLH) is a potentially fatal disorder of the immune system that typically occurs in the paediatric population. Diagnosing this rare disease in the adult population is challenging, particularly during pregnancy.

Case presentation

We present a case of a gravid patient developing HLH at week 13 of gestation undergoing a medical termination of pregnancy at 27 weeks due to anhydramnios and associated stopped foetal growth.

Conclusions

Disease triggers could vary from a simple viral infection to the pregnancy as such causing the disorder. Treatment should benefit the mother and limit the foetal harm.

Management of hemophagocytic lymphohistiocytosis in pregnancy: Case series study and literature review

Aim

The diagnosis and treatment of hemophagocytic lymphohistiocytosis (HLH) in pregnancy is challenging due to its rarity. We aim to analyze and summarize the clinical characteristics of HLH in pregnancy, and to discuss effective diagnostic and treatment options.

Methods

Thirteen patients with HLH during pregnancy who were diagnosed and treated at the Peking Union Medical College Hospital of the Chinese Academy of Medical Sciences from January 2000 to December 2019 were studied retrospectively. We collected data on treatment regimens and on maternal and pregnancy outcomes.

Results

All patients had a singleton pregnancy, with a median age of 28 years (range, 22–33 years) and a median gestational age of 23 weeks (7–36 weeks). Twelve patients received corticosteroids, and four patients (with/without intravenous immunoglobulin) showed a curative effect. Two patients who were treated with dexamethasone and etoposide after termination of pregnancy achieved complete remission. Two patients attained remission after termination of pregnancy. Four pregnant women died, and the mortality rate was 30.8% (4/13). Fetal or neonatal death up to 1 week after delivery occurred in eight (61.5%) pregnancies.

Conclusions

Early diagnosis and treatment are important for maternal survival, and corticosteroids are the first choice for most patients with HLH during pregnancy. For patients who do not respond to corticosteroids, etoposide and termination of pregnancy may be life‐saving.

Haemophagocytic lymphohistiocytosis in pregnancy

Haemophagocytic lymphohistiocytosis is a life-threatening systemic inflammatory syndrome defined by persistent fever, cytopenia and multi-organ dysfunction. Primary haemophagocytic lymphohistiocytosis classically presents in childhood as a result of genetically abnormal perforin or inflammasome function, leading to the aberrant release of pro-inflammatory cytokines causing a hyperinflammatory state. Secondary haemophagocytic lymphohistiocytosis is an acquired phenomenon occurring at any age as a result of immune dysregulation to a specific trigger such as infection, haematological malignancy or autoimmune disease. Secondary haemophagocytic lymphohistiocytosis occurring in the pregnant woman represents a diagnostic challenge and carries a significant mortality. This has led to its first inclusion in the fourth Mothers and Babies: Reducing Risk through Audits and Confidential Enquiries across the United Kingdom annual maternal report in 2017. This article presents an overview of haemophagocytic lymphohistiocytosis, reviews the literature on haemophagocytic lymphohistiocytosis in pregnancy, suggests diagnostic pathways and explores the safety and efficacy of existing and potential treatment strategies for haemophagocytic lymphohistiocytosis occurring during pregnancy.

[Clinical diagnosis and treatment of perinatal stage hemophagocytic lymphohistiocytosis]

Objective: To analyze the clinical features of patients with hemophagocytic lymphohistiocytosis (HLH) during perinatal stage. Methods: From January 2011 to October 2016, the obstetric materials, clinical features, associated disease/factors and therapeutic outcomes were studied in 11 patients with HLH in perinatal period. Results: In these 11 patients, 9 were primipara. As for the onset time of HLH, 5 were before delivery and 6 were after delivery. Six were complicated with other associated disease/factors, and infection was the commonest (5/6) . Treatment included glucocorticoid + fludarabine in 1 case, HLH-94/04 protocols in 9 cases, and monotherapy corticosteroids in 1 case. Two patients died eventually. Conclusions: Perinatal HLH is commonly observed in the pregnancy/postpartum related HLH (28th week of pregnancy to one week after delivery) . Infection is still the commonest associated factors. HLH-94/04 protocols after the cessation of pregnancy may be effective, but the cessation of pregnancy itself may not be enough for the perinatal stage related-HLH. The perinatal stage related-HLH still has a better outcome than the other subtype of secondary-HLH.

Requirement for etoposide in the treatment of pregnancy related hemophagocytic lymphohistiocytosis: a multicenter retrospective study

Background

Hemophagocytic lymphohistiocytosis (HLH) is a rare severe clinical syndrome. HLH manifesting during pregnancy has been paid much attention in recent years. Despite the specificity of pregnancy-related HLH, there has not been any consensus regarding its treatment. According to a previous study, corticosteroid/IVIG is the mainstream therapy; however, the efficacy is controversial. Etoposide is an important agent in the HLH-94 regimen; nevertheless, its use is limited because of possible toxicity to the fetus. Methods: In this study, we summarized 13 cases from 4 medical institutions from April 2011 to April 2018. Treatment regimens and outcomes were observed.

Results

The median age was 26 (20–36) years old. The median gestational age was 28 (10–35) weeks. In these 13 patients, 10 were treated with methylprednisolone/IVIG and was effective in only two patients. In 6 patients who used etoposide during their treatment, all achieved remission. The median time from onset of disease to use of etoposide was 36 (17–131) days. Five of these 6 patients were treated with corticosteroids with/without IVIG before etoposide. One patient with pulmonary tuberculosis and one with lymphoma were treated according to etiology and achieved long survival.

Conclusion

For treatment of pregnancy-related HLH, particularly for patients who do not respond to corticosteroids/IVIG therapy, etoposide should be used bravely. Nevertheless, suitable dosages and toxic and side-effects require further clinical observation.

Hemophagocytic Lymphohistiocytosis in Pregnancy: A Case Series and Review of the Current Literature

Background

Hemophagocytic lymphohistiocytosis (HLH) is a rare disease that can be fatal in pregnancy. We report two cases of severe HLH that highlight etoposide use in pregnancy.

Case 1

28-year-old G2P1 with lupus presented at 18 weeks with acute hypoxic respiratory failure, hepatic dysfunction, leukopenia, thrombocytopenia, and elevated ferritin. Bone marrow biopsy confirmed HLH. Etoposide and corticosteroid treatment was initiated per HLH protocol; however clinical status declined rapidly. Fetal demise occurred at 21 weeks and she subsequently suffered a massive cerebral vascular accident. She was transitioned to comfort measures and the patient deceased.

Case 2

37-year-old G4P3 presented at 25 weeks with fever, acute liver failure, thrombocytopenia, and elevated ferritin. HLH treatment was initiated, including etoposide, and diagnosis confirmed with liver biopsy. Fetal growth restriction was diagnosed at 27 weeks. Delivery occurred at 37 weeks. The neonate was found to be CMV positive despite negative maternal serology.

Conclusion

The addition of etoposide to corticosteroid use is a key component in HLH treatment of nonpregnant individuals. While this is usually avoided in pregnancy, the benefit to the mother may outweigh the potential harm to the fetus in severe cases and it should be strongly considered.

Hemophagocytic lymphohistiocytosis in the setting of HELLP Syndrome

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening hyper activation of the immune system. Rare cases associated with HELLP syndrome and other similar conditions in pregnancy have been reported. Despite the improved survival rates with etoposide and dexamethasone-based regimens, HLH remains a challenging disease. Experience in pregnant patients is exceedingly rare.

Natural killer/T-cell lymphoma and secondary haemophagocytic lymphohistiocytosis in pregnancy

Haemophagocytic lymphohistiocytosis (HLH) is a rare and potentially fatal disorder. It is challenging to diagnose due to its rarity and variation in clinical presentation, laboratory abnormalities and underlying aetiologies. A reproductive-aged woman, gravida 2 para 1001 at 27 weeks gestation presented with fever, hypotension and subacute upper respiratory infection. She delivered a male infant by caesarean section secondary to fetal distress. Subsequently, she was diagnosed with T-cell lymphoma and secondary HLH. Despite management with supportive care and multiple chemotherapeutic agents, she ultimately died of multiorgan failure. Patients with HLH secondary to malignancy have a particularly poor prognosis. This case highlights the importance of considering secondary HLH in the differential diagnosis of a patient with fever, pancytopenia and systemic symptoms of unclear aetiology in pregnancy.

Hepatitis during pregnancy: A case of hemophagocytic lymphohistiocytosis

Hemophagocytic lymphohistiocytosis (HLH) is a rare but severe and potentially fatal syndrome that can occur during pregnancy. A 36 years-old woman, at 29 weeks of gestation, presented with itchiness and jaundice since a week. On clinical examination she was apyrexial and frankly icteric. Laboratory data showed evidence of acute hepatitis. A complete work-up was made excluding viral hepatitis (HAV, HEV, HBV, HCV, HHV6, CMV, EBV) and autoimmune liver disease. Liver diseases related to pregnancy were not completely excluded. A liver biopsy was performed and firstly interpreted as showing features of acute hepatitis. The clinical situation worsened, she developed fever with signs of fetal distress and emergent delivery was done. A second look at the liver biopsy showed features compatible with HLH, which was also confirmed on bone marrow biopsy. Extensive work-up with exclusion of infectious and malignant diseases, lead us to the diagnosis of HLH secondary to pregnancy and short term steroid therapy was started. She then completely recovered and didn't present any relapse after 4 months of follow up. HLH during pregnancy is very rare and this is the first case of HLH presenting as acute hepatitis and diagnosed on a liver biopsy.

Pregnancy-associated hemophagocytic lymphohistiocytosis secondary to NK/T cells lymphoma: A case report and literature review

RATIONALE

Hemophagocytic lymphohistiocytosis (HLH) occurs primarily in pediatric population, or secondary to malignancy, infection, or autoimmune disease. This disease is rare and prognosis is generally poor. Only a small number of cases during pregnancy have been reported in literature.

PATIENT CONCERNS

We report a case of pregnancy-associated HLH secondary to natural killer (NK)/T cells lymphoma. She was admitted at 30 weeks and 3 days of pregnancy with complaints of abdominal pain and fever as high as 39.2°C. The patient was found to have splenomegaly, pancytopenia, and acute hepatic failure.

DIAGNOSES

A subsequent bone marrow biopsy revealed focal hemophagocytosis and atypical lymphoid cells. The splenic pulp also contained a large number of tissue cells proliferating and devouring mature red blood cells, lymphocytes, and cell debris. On the basis of these findings, we diagnosed the case as pregnancy-associated hemophagocytic lymphohistiocytosis secondary to NK/T cells lymphoma.

INTERVENTIONS

Treatment consisted with dexamethasone and etoposide in combination with rituximab.

OUTCOMES

Due to timely termination of pregnancy, the neonate was in good condition. However, the patient died on the 18th day postoperation due to multiorgan failure.

LESSONS

We recommend that HLH be considered as differential diagnosis in a pregnant patient complaining of persistent fever, cytopenia, or declining clinical condition despite delivery of the baby. Prompt diagnosis and treatment is essential and fetal outcomes should also be considered. The decision to terminate a pregnancy and initiate chemotherapy during pregnancy with malignancy-associated HLH (M-HLH) needs to be further investigated in a larger cohort.

Haemophagocytic lymphohistiocytosis presenting as HELLP syndrome: a diagnostic and therapeutic challenge

Haemophagocytic lymphohistiocytosis (HLH) is a rare, potentially fatal, haematological disorder, which can be clinically challenging to diagnose and manage. We report a case of HLH in a previously healthy 33-year-old primigravida. The patient presented at 22 weeks gestation with dyspnoea, abdominal pain, anaemia, thrombocytopenia and elevated liver enzymes suggestive of HELLP syndrome.HELLP, a syndrome characterised by haemolysis, elevated liver enzymes and low platelets is considered a severe form of pre-eclampsia. Despite delivery of the fetus, her condition deteriorated over 3-4 days with high-grade fever, worsening thrombocytopenia and anaemia requiring transfusion support. A bone marrow biopsy showed haemophagocytosis and a diagnosis of HLH was made. Partial remission was achieved with etoposide-based chemotherapy and complete remission following bone marrow transplantation. Eleven months post-transplant, the disease aggressively recurred, and the patient died within 3 weeks of relapse.

Idiopathic Hemophagocytic Lymphohistiocytosis During Pregnancy Treated with Steroids

Hemophagocytic lymphohistiocytosis (HLH) is a rare and severe clinical syndrome characterized by a dysregulated hyperinflammatory immune response. The diagnosis of HLH during pregnancy is especially challenging due to the rarity of this condition. The highly variable clinical presentation, laboratory findings, and associated diagnoses accompanying this syndrome further complicate the problem. A pronounced hyperferritinemia in the setting of systemic signs and symptoms along with a negative infectious and rheumatological workup should raise suspicions for HLH. While treatment ideally consists of immunosuppressive chemotherapy and hematopoietic stem cell transplant, the potential toxicity to both the pregnant woman and the fetus poses a challenging decision. We report the first case of idiopathic HLH presenting as fever of unknown origin in a pregnant woman successfully treated with steroids.
