Abstract:
Rationale: Paraquat, a highly toxic bipyridyl herbicide lacking a
specific antidote, poses severe risks upon ingestion. However, the
diagnosis of paraquat poisoning is complicated by its nonspecific
initial symptoms, particularly when a detailed exposure history is
not provided.
Patient’s Concern: A 33-year-old man inadvertently ingested
an unknown liquid and presented to medical services a day later
with complaints of ongoing nausea, vomiting, and diarrhea.
The assessment revealed elevated serum creatinine, signaling
acute kidney injury, initially thought due to gastroenteritis and
dehydration.
Diagnosis: Acute renal insufficiency due to paraquat poisoning.
Interventions: The treatment involved fluid resuscitation and
antibiotics, but his decline led to intensive care unit transfer.
Subsequent chest computed tomography scans indicated lung
changes indicative of paraquat poisoning. A detailed history review
and comprehensive blood and urine toxicology screens confirmed
the diagnosis. Subsequently, aggressive interventions such as
hemoperfusion and continuous renal replacement therapy were
initiated, yet there was a further decline in respiratory function,
necessitating mechanical ventilation. The prognosis was poor, and
ultimately, the family chose to withdraw care.
Outcomes: The patient succumbed to his illness.
Lessons: This case underscores the importance of promptly and
accurately diagnosing paraquat poisoning, as its vague early signs
can lead to diagnostic delays, crucial due to the condition’s rapid
progression. Alertness to paraquat poisoning is essential in patients
with sudden gastrointestinal and renal symptoms post-exposure.
Additionally, it underscores the necessity for public health measures
to avert paraquat ingestion and advance therapeutic approaches
