Colchicine poisoning: Case report of three homicides in a family.
Article in Heliyon, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Colchicine is a common therapeutic agent for inflammatory conditions such as gout, yet its narrow therapeutic range frequently results in cases of overdose and subsequent poisoning. Acute colchicine poisoning can be difficult to identify due to its nonspecific clinical manifestations, posing a diagnostic challenge for emergency physicians without a clear history of colchicine ingestion. Case presentation: This report describes a tragic case of acute colchicine poisoning that resulted in three familial homicides. The patients presented with fever, abdominal pain, and diarrhea, which rapidly escalated to shock during their emergency department visits. Laboratory tests revealed a marked leukocytosis, mild elevation in procalcitonin (PCT), significantly elevated creatine kinase (CK) and CK-MB levels, and liver function abnormalities. Despite treatment with carbapenem antibiotics and aggressive fluid resuscitation, the patients' condition deteriorated, marked by a progressive decline in leukocytes and neutrophils. Initially misdiagnosed as septic shock, the ineffectiveness of the standard treatment protocols led to a fatal outcome for all three individuals. Conclusion: Emergency physicians should consider acute colchicine poisoning as a differential diagnosis in patients presenting with shock and the following clinical indicators: (1) pronounced increase in peripheral leukocytes with a disproportionate rise in neutrophils; (2) discordance between the level of serum procalcitonin and the severity of presumed septic shock; (3) early increase in serum creatine kinase (CK) and CK-MB; (4) poor response to antibiotics and resuscitative efforts, accompanied by a continuous decrease in white blood cells and neutrophils. This case underscores the critical need for awareness of colchicine toxicity in the emergency setting, particularly when the clinical presentation mimics septic shock but fails to respond to standard treatments.
