A report of a rare case of autoimmune haemolytic anaemia in a patient with Hodgkin's disease in whom routine serology was negative

Autoimmune Hemolytic Anaemias in Pregnancy: Experience in a Tertiary Care Hospital in South India

Background

Autoimmune hemolytic anaemia is very rare and there is limited data regarding their pregnancy outcomes. Hence we aimed to study the maternal and perinatal outcomes in pregnancies with autoimmune hemolytic anaemias (AIHA).

Methods

A retrospective descriptive study of pregnant women with AIHA, who delivered at SJMCH between January 2011 and January 2016 was carried out. Their antenatal and labour records were reviewed and demographic details noted.The primary outcome measures studied were-the prevalence of AIHA, gestational age at delivery, antepartum, intrapartum and postpartum complications, mode of delivery and requirement of transfusion of blood and blood products. The secondary outcome measures studied included neonatal outcomes such as low birth weight, intrauterine growth restriction and need for intensive care. The data is presented as descriptive statistics, including means and percentage.

Results

The prevalence of AIHA was (18/12,420) 0.14%. The mean gestational age at delivery was 34 weeks; 100%, 77% and 50% had antenatal, intra partum or postpartum complications, respectively. 44% had preeclampsia, 38% intrauterine growth restriction and 16% preterm labour. 83% required additional drugs for treatment of AIHA.72% had vaginal delivery; 28% had caesarean delivery; 33% were transfused antenatally and 22% postnatally; 50% of the babies were preterm and required intensive care, 66% had low birth weight. There was no maternal mortality.

Conclusion

Multidisciplinary approach, early diagnosis and detection of autoimmune hemolytic anaemia and complications, good antenatal care, judicious transfusions and delivery at tertiary care centre are the keys to successful outcomes.

Autoimmune Hemolytic Anemia as Presenting Symptom of Hodgkin Lymphoma

Autoimmune hemolytic anemia (AIHA) is related to an underlying condition in an estimated 50 to 60%, while the remaining is idiopathic, as a result of a combination of immune activation, deficiency, or dysregulation. AIHA is associated with viral infections, autoimmune disorders, immunodeficiencies, lymphoproliferative disorders, and pregnancy. AIHA has predictive properties and may be a harbinger of future lymphoproliferative disorders in up to 20% of AIHA cases. Autoimmune hemolytic anemia (AIHA) has been associated with lymphoproliferative disorders particularly chronic lymphocytic leukemia and non-Hodgkin lymphoma. Rarely is it seen in Hodgkin disease. In the following report, we describe the presentation of AIHA, ultimately resulting in the diagnosis of nodular sclerosis Hodgkin lymphoma (stage III). From the limited reports and reviews available, it is understood that advanced Hodgkin (stage III or IV) of nodular sclerosis (NS) or mixed cellularity (MC) types portend a stronger affiliation to AIHA. The majority of AIHA-associated Hodgkin lymphoma presents as stage III or IV disease with the hemolysis being the presenting symptom, as in this case. The mainstay of AIHA therapy has been corticosteroids; however, this first-line regimen appears to be less effective when treating AIHA in the setting of HL. The exact mechanism of AIHA related to HL is unclear, and it may be thought to be that tumor cell produced autoantibodies. Other hypotheses include paraneoplastic phenomena or more, perhaps immunity to tumor cells may cross-react with antigens on the red cells. Although these mechanisms require further investigation, the relationship of the AIHA and HL represents a piece to a larger puzzle between autoimmune disorders and lymphoproliferative conditions.

A Rare Case of Successfully Treated Coombs Negative Immune Haemolytic Anaemia in Pregnancy

Immune haemolytic anaemia in pregnancy, although rare, but it can be life threatening. Severe anaemia with jaundice, unresponsive to blood transfusion can clinch the diagnosis of immune haemolytic anaemia. Our patient was a 27-year-old second gravida, with all the above features, but there was diagnostic challenge as her Coombs test was negative. A high index of suspicion and rapid response to glucocorticoids, pointed towards the diagnosis. Thereafter, the course of pregnancy and postpartum period was uneventful. Thus, successful maternal and fetal outcome can be achieved with prompt diagnosis and treatment.
