[Hereditary coproporphyria from clinician's point of view--a case report].

INTRODUCTION: Acute hepatic porphyrias can mimic a range of unrelated diseases and conditions that may occur independently of porphyria and trigger their initial manifestations and further attacks.

CASE REPORT: A 46-year-old female patient was subjected to cholecystectomy for biliary colic. Histopathological analysis revealed acute purulent exacerbation of chronic cholecystitis. On the 8th day post surgery, the patient was rehospitalized for nausea, abdominal pain, weakness and faintness, poor general condition, hypertension, tachycardia, apathy and profuse sweating. Laboratory findings revealed hyponatremia, hypokalemia, and metabolic alkalosis. Exploratory laparotomy did not detect a pathomorphological substrate. The patient was transferred to surgery department of the tertiary care institution. Due to metabolic imbalance, she was transferred to the Department of Endocrinology with signs of paleness, profuse sweating, tachycardia, and tachydyspnoea. The cardiologist performed echocardiography. The patient was diagnosed to have acute left ventricular failure and sub-acute myocardial infarction and transferred to the Department of Cardiology. Coronarography findings were normal. Cramps and pain in the legs with sensory loss, general weakness, apathy and mental confusion suggested acute hepatic porphyria. Thus, hereditary coproporphyria was diagnosed in the second month of illness. The treatment was continued at the Department of Gastroenterology. Clinical manifestations included polyneuropathy, flaccid paraparesis and acute brain syndrome, precordial oppressions and tachycardia. Haem arginate and hypertonic glucose were applied. The condition of the patient gradually improved.

CONCLUSION: Porphyrias should always be taken into consideration in doubtful, frequently dramatic clinical pictures characterized by neurovisceral symptoms and precipitating factors of acute porphyria attacks must never be neglected.
