Summary
Anemia affects 25% of systemic sclerosis patients, often due to iron deficiency or kidney issues. This study highlights autoimmune hemolytic anemia as a rare but significant cause, suggesting a shared autoimmune link.
Area of Science:
- Rheumatology
- Hematology
- Autoimmune Diseases
Background:
- Progressive systemic sclerosis (PSS) is a complex autoimmune condition.
- Anemia is a common comorbidity in PSS, affecting approximately 25% of patients.
- Known causes of anemia in PSS include iron deficiency (often from gastrointestinal bleeding) and renal failure, but the etiology remains unclear in many cases.
Observation:
- A case report of a 59-year-old female patient with incomplete CREST syndrome (Calcinosis, Raynaud's phenomenon, Esophageal dysmotility, Sclerodactyly, Telangiectasia) is presented.
- The patient presented with autoimmune hemolytic anemia (AIHA).
Findings:
- Autoimmune hemolytic anemia is a rare cause of anemia in patients with systemic sclerosis.
- This case underscores the importance of considering less common etiologies for anemia in PSS patients.
Implications:
- The occurrence of AIHA in PSS indirectly supports the potential autoimmune pathogenesis of systemic sclerosis.
- Further research into the diverse causes of anemia in PSS is warranted.
- This finding may prompt clinicians to investigate autoimmune hemolytic anemia in PSS patients presenting with unexplained anemia.
