ABSTRACT

Background:

Cold agglutinin disease (CAD) is a rare and poorly understood disorder affecting 15% of patients with autoimmune hemolytic anemia. Few studies have assessed CAD symptoms and their impact on daily life, and these did not address the patients’ perspective.

Objective:

The aim of this research is to increase the knowledge on CAD through a patient-centric survey and to gain a better understanding of the burden of this disease.

Methods:

We conducted an internet-based survey in September 2020 among American patients registered on the CAD Unraveled website and members from the Cold Agglutinin Disease Foundation.

Results:

Fifty respondents were included in the study. Ninety percent of patients reported having experienced fatigue. Fatigue was mainly reported on a daily basis, and almost a third said it was constant through the day. It has also been shown that CAD had a great impact on physical well-being, emotional well-being, social life, and patients’ household finances. The disease varies over time, with or without symptoms. Eighty-eight percent of patients reported previous episodes of increased intensity/sensitivity of their CAD symptoms, with a mean number of episodes reported of 4.5 during the past year. More than half of the patients considered their disease as moderate or severe, and over 40% of the study group reported that their symptoms had worsened since the time of diagnosis.

Conclusions:

Our study has raised new data on CAD symptoms, in particular on the importance and type of fatigue, and the fluctuation of CAD symptoms.
