Asthma attacks: Patients who survived paraquat poisoning

Abstract

A patient who survived acute paraquat (PQ) poisoning for more than 5 years was followed up in the emergency room. The patient had recurrent coughing and wheezing one month after discharge. Re-examination of chest CT showed increased dual lung texture. Spirometry suggested severe ventilatory dysfunction while bronchial dilation test was positive. The serum IgE level was significantly high. It is considered that patients with acute PQ poisoning may develop asthma in the long term.
