Diagnosis of Warm Autoimmune Hemolytic Anemia
A 76-year-old female presented with silent jaundice, lacking associated symptoms, but with dark urine. Lab results indicated anemia with high white blood cell count primarily lymphocytes, low platelet count, and elevated total bilirubin. CT scan showed splenomegaly and diffuse lymphadenopathy. A Coombs test confirmed warm autoimmune hemolytic anemia secondary to CLL, managed with prednisone and rituximab, leading to improved hemoglobin levels.
Diagnostic Approach and Clinical Reasoning
Initially focusing on the possibility of a hemolytic issue, the discussion evaluated various causes of jaundice, including liver-related processes. The patient's history and lab findings guided the consideration of autoimmune hemolytic anemia, further confirmed by a positive Coombs test. The diagnostic process highlighted the importance of integrating patient history, physical exam, and laboratory results to arrive at the correct diagnosis.
Interactive Learning and Problem Representation
The episode showcased a diagnostic journey involving interactive discussions among participants. The approach utilized system one thinking, emphasizing the systematic breakdown of symptoms, lab findings, and disease mechanisms. Participants navigated hypotheses and treatment decisions, with a focus on integrating clinical clues to refine and verify potential diagnoses. The engaging dialogue promoted active learning and case-based reasoning.
