Pembrolizumab-Induced Simultaneous and Refractory Systemic Capillary Leak and Cytokine Release Syndromes: A Case Report
Bibliographic record
Abstract
Systemic Capillary Leak Syndrome (SCLS) and Cytokine Release Syndrome (CRS) have both been described as rare but severe adverse reactions induced by Programmed cell death protein 1 (PD-1) inhibitors such as pembrolizumab. We report the case of a 40-year-old woman undergoing treatment with pembrolizumab for a stage 4 cervical squamous cell carcinoma who presented with anasarca, hypotension, hemoconcentration and signs of multisystemic inflammation. After elimination of alternative causes such as nephrotic syndrome, cardiac dysfunction and cirrhosis, she was diagnosed with both pembrolizumab-induced SCLS and CRS. She was successfully treated with a multimodal treatment approach including intravenous immunoglobulins, steroids, diuretics and axitinib for SCLS as well as ruxolitinib for CRS. After several months of hospitalization, her symptoms finally improved with this treatment regimen, and she was able to attain euvolemic state and be discharged from the hospital. This case highlights certain rare and severe adverse effects of treatment with PD-1 inhibitors. Furthermore, it proposes a novel therapeutic approach for similar cases based upon probable underlying physiopathological mechanisms in SCLS and CRS.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
