The role of platelet activation in determining response to therapy in patients with primary nephrotic syndrome.

abstract：:A 38-year-old female patient was diagnosed with anemia for 3 years. Medical examination showed slight splenomegaly (250 × 62 mm), thrombocytopenia (platelets 51 × 109/L), anemia (Hb levels 107 g/L), and β-glucocerebrosidase activity (GBA) in leukocytes was lower than normal. Microscopic findings of bone marrow smear d...
