GSTM1 and hypercalcemia disease: Ultimately, by the final month of hospitalization, the average Hb level increased to 11.1 g/dL, with an overall average of 10.17 g/dL throughout the hospitalization period, thereby aligning with the KDIGO recommended range of 10.0 to 12.0 g/dL.[19] Patients undergoing hemodialysis are prone to hypercalcemia, which is associated with early mortality.[31] In this patient, calcium levels demonstrated a stable increase during the later stages of hospitalization, satisfying the KDOQI standards.[17] This indicates that appropriate management measures have been effectively implemented.
