Abstract
Introduction

Cold agglutinin autoimmune haemolytic anaemia (AIHA) secondary to systemic lupus erythematosus (SLE) is a rare manifestation. There are no cohorts or case series that allow us to evaluate the characteristics of this group of patients.

Objective

To describe the clinical and serological characteristics of patients with systemic lupus erythematosus (SLE) and cold agglutinin hemolytic anemia.

Materials and methods

We present two cases with SLE that debuted with cold agglutinin AHAI, their clinical and immunological profile and response to immunosuppressive treatment.

Results

Eleven cases reported in the literature from 1950 to 2023 are described.

Conclusion

Cold agglutinin AIHA secondary to SLE is rare, with unclear clinical features compared to idiopathic forms and usually not associated with manifestations or serious organic involvement.

Keywords:
Systemic lupus erythematosus
Cold agglutinins
Autoimmune haemolytic anaemia
