Mixed autoimmune haemolytic anaemia in a COVID-19 patient.
Introduction: Mixed warm and cold autoimmune haemolytic anaemia (AIHA) secondary to COVID-19 is rarely reported.
Case report: We present a case of a 65-year-old Malay lady with no known medical illness, who was admitted for COVID-19 category 3 and mixed warm and cold AIHA. She presented with lethargy, productive cough and on and off fever. Blood investigations showed severe anaemia with spurious macrocytosis, increased lactate dehydrogenase (LDH) and total bilirubin with indirect bilirubin predominance. On full blood picture (FBP), there was normocytic normochromic anaemia with reticulocytosis, red blood cells clumping and NRBC's were seen. Both anti-IgG and anti-C3d were positive for monospecific Coombs test. For indirect Coombs test, auto-IgG and cold agglutinin were detected.
Discussion: These findings were consistent with mixed warm and cold AIHA. She was treated with intravenous methylprednisolone, before being changed to high dose oral prednisolone. A total of 3 units packed cells were transfused.
期刊介绍：
The Malaysian Journal of Pathology is the official journal of the College of Pathologists, Academy of Medicine Malaysia. The primary purpose of The Journal is to publish the results of study and research in Pathology, especially those that have particular relevance to human disease occurring in Malaysia and other countries in this region. The term PATHOLOGY will be interpreted in its broadest sense to include Chemical Pathology, Cytology, Experimental Pathology, Forensic Pathology, Haematology, Histopathology, Immunology, Medical Microbiology and Parasitology. The Journal aims to bring under one cover publications of regional interest embracing the various sub-specialities of Pathology. It is expected that the articles published would be of value not only to pathologists, but also to medical practitioners in search of a scientific basis for the problems encountered in their practice, and to those with an interest in diseases which occur in the tropics.
