Workup revealed new onset of anemia (Hgb 10.5 g/dL), thrombocytopenia (platelets 23 × 109/L) with high lactate dehydrogenase (LDH 2,150 U/L), low haptoglobin 29 mg/dL, and new onset AKIN III, anuric renal failure (creatinine 4.63 mg/dL from baseline 1.3 mg/dL). Here, HP is linked to anemia (phenotype).
