Paroxetine Serotonin Syndrome: Case Report of Fatal Outcome

Okay, here’s a breakdown of the key facts from the provided text, focusing ‍on the patient’s case and the attempts to address paroxetine toxicity:

Patient Presentation & ​Initial Situation:

* The patient experienced paroxetine poisoning.
* Initially,⁤ the patient ⁤was managed conservatively.
* The patient⁣ developed a tracheal ‌injury⁢ requiring veno-venous ⁤Extracorporeal Membrane Oxygenation‌ (vv-ECMO).

cytosorb™ attempt:

* ⁣​ Due to the vv-ECMO, cytosorb™ (a hemadsorption device) ​was added to the circuit as an experimental treatment.There are no formal guidelines recommending its use in this situation.
* A 6-hour CytoSorb™ treatment was performed.
* The‌ cytosorb™​ treatment was ineffective: It did not reduce paroxetine levels, nor did it lead to clinical ​advancement.
* Limitation of CytoSorb™ assessment: The study only measured total blood paroxetine ⁢concentrations. They⁣ did not sample blood before and after the CytoSorb™ filter,⁤ so they couldn’t determine how much paroxetine​ the device actually removed.

Cause of Death & differential Diagnoses:

* ⁣ The patient ultimately died from Acute Respiratory Distress Syndrome (ARDS).
* Aspiration pneumonia​ was considered, but deemed unlikely: Repeated tests‌ (bronchoalveolar lavage and blood cultures) were negative for ⁢pathogens. Though, it couldn’t be completely ruled out due to the initial altered mental status.
* Infectious causes: Empiric antibiotic treatment was ‍started and later switched ⁤to meropenem due to clinical deterioration. Prior ⁤antibiotic use may have affected test results.
* TRALI (Transfusion-Related Acute ⁣Lung injury) was excluded: The patient hadn’t received blood ⁣products.
* ⁤ Paroxetine-induced ARDS: The text highlights⁤ that severe ARDS has been reported as a complication of paroxetine⁤ poisoning‍ in‌ previous case reports (references 23 & 24). one case showed recurrent ARDS resolving with paroxetine discontinuation.

In essence, the case describes a severe paroxetine⁢ poisoning complicated by tracheal injury and ARDS. An experimental attempt to use CytoSorb™ was unsuccessful, and the patient’s death ⁤was attributed​ to ARDS, with a possible (but unconfirmed) contribution from paroxetine toxicity itself.
