Clinical features of acute PQ intoxication can be classified into three categories: (1) Mild poisoning (<20<span class="elsevierStyleHsp" style=""></span>mg/kg of 20% PQ), in which patients have minor gastrointestinal symptoms and a full recovery; (2) Severe poisoning (20–40<span class="elsevierStyleHsp" style=""></span>mg/kg of 20% PQ) were patients develop sore tongue, shortness of breath, agitation, abdominal discomfort, head lightness, tachypnea, tachycardia, AKI, and acute lung injury with progressive pulmonary fibrosis. Death occurs 2–3 weeks after a protracted clinical curse, as result of respiratory failure; and (3) Fulminant poisoning (>40<span class="elsevierStyleHsp" style=""></span>mg/kg of 20% PQ) with multiple organ failure leading to death within hours to few days after ingestion.<a class="elsevierStyleCrossRefs" href="#bib0060"><span class="elsevierStyleSup">2,5</span></a> Several pathways underlie the critical toxicity of PQ, such as its elevated concentration reached in lungs due to its high affinity for alveolar cells, which form reactive oxygen species that cause cellular damage via lipid peroxidation, activation and release of NF-κβ, tumor necrosis factor-α, interleukin (IL) 1 and IL-6, transforming growth factor (TGF)-β1, that produce mitochondrial damage and apoptosis. PQ-induced lung injury has two phases: characterized by an early destruction of alveolar epithelial cells and a proliferative period with infiltration of inflammatory cells, alveolitis, edema, and finally pulmonary fibrosis.<a class="elsevierStyleCrossRefs" href="#bib0080"><span class="elsevierStyleSup">6,7</span></a></p><p id="par0035" class="elsevierStylePara elsevierViewall">The diagnosis of PQ poisoning is easy with an accurate history of exposure, physical exam – like in this case – and the specific laboratory tests of urine sodium dithionite screening test.

Oxygen supplementation should be avoided – if possible –, unless PaO<span class="elsevierStyleInf">2</span> is less than 60<span class="elsevierStyleHsp" style=""></span>mmHg, because it can potentiate paraquat-induced lung injury.

Evolucionó rápidamente a síndrome de distrés respiratorio agudo severo, ameritando intubación endotraqueal, sin embargo, se sabe que el paraquat genera especies reactivas de oxígeno que producen daño celular a través de la peroxidación de lípidos, activación mitocondrial y apoptosis posterior a la exposición con oxígeno, por lo que en estos casos es muy delgada la línea entre el riesgo y beneficio de la oxigenoterapia. A pesar de recibir tratamiento oportuno, el grave deterioro hemodinámico y respiratorio evolucionó a falla multiorgánica y posteriormente al fallecimiento del paciente.
