What Is Known And Objective:
Wilson's disease (WD) is an inherited disorder in which defective biliary excretion of copper leads to its accumulation. Sodium dimercaptosulphonate (DMPS) is used as the primary therapy in China.
Case Description:
We report two cases, with WD and G6PD deficiency, who developed haemolysis on treatment with DMPS, without any other known risk. After withdrawal of DMPS and administration of dexamethasone and packed red blood cells, the patients recovered.
What Is New And Conclusion:
Clinicians should keep in mind haemolysis as a potentially life-threatening side effect of DMPS in patients with G6PD.

Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
