A 28-year-old man (treated at academic medical centre in Guatemala) developed diarrhoea: The man, who had mitochondrial myopathy due to thymidine kinase 2 deficiency, started receiving oral deoxythymidine [deoxythymidine monophosphate] and oral decitabine [deoxycytidine monophosphate] at the age of 26 years on a compassionate use basis. He had dysphagia, and was on enteric feeding. In 2015, after 11 months of the therapy, he was transitioned to oral deoxythymidine 350 mg/kg/day and oral decitabine [deoxycytidine] 350 mg/kg/day on a compassionate...
