Doctors dig out root cause of drug-induced thrombocytopenia: case study

A middle-aged woman’s ill-fated pursuit of weight loss with the aid of a Mexican herbal supplement landed her in hospital with severe cardiologic and haematologic complications, US doctors report.
The 55-year-old patient presented to ED after experiencing nausea, weakness, abdominal pain and noticing persistent low heart rate readings on her smart watch for about a month.
An ECG showed bradycardia (48bpm) and a prolonged PR interval followed by a non-conducted QRS complex, which her doctors said was indicative of a Mobitz type 1 second degree atrioventricular block.
They also noted elevated calcium (2.76mmol/L) and severe thrombocytopenia (platelet count 22×109/L).
