Abstract

fetched live from OpenAlex

) is usually associated with skin necrosis; however, it can lead to more significant morbidity including acute hemolytic anemia, rhabdomyolysis, disseminated intravascular coagulopathy and death. Here we highlight a case using plasmapheresis as treatment for acute hemolytic anemia caused by the bite of a brown recluse spider. A 49-year-old male presented to the emergency room 5 days after suffering a spider bite due to worsening symptoms. He had worsening pain at the site of the bite, diffuse body myalgias, darkening of his urine, chills, and shortness of breath. Hematology was consulted to assist in the management of hemolytic anemia refractory to multiple blood transfusions, worsening acute kidney failure requiring hemodialysis, and concern for impending death. After a literature review suggesting plasmapheresis may be beneficial in this scenario, the case was discussed with the local blood bank, and plasmapheresis was initiated. The patient underwent plasmapheresis with albumin for 2 days and the patient's hemoglobin improved and stabilized. Therapy of loxoscelism is directed at limiting the dermatonecrosis at the site of the envenomation and in cases of systemic illness supportive care is recommended. Therapeutic plasma exchange has been shown efficacious in treating snake envenomation, but there are limited data detailing its use for brown recluse spider envenomation. Here we present a case to highlight the benefit of plasmapheresis in a patient with acute hemolytic anemia secondary to a brown recluse spider bite.

Teacher imitation

Not 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.
