Just a Bad Case of Cotton Fever: A Case Report and Literature Review.

Fever is one of the most commonly seen presentations in intravenous drug abusers. "Cotton Fever" is a benign condition, unrecognized among the medical community. It is characterized by a systemic inflammatory response syndrome occurring within minutes of intravenous (IV) drug use. Patients present to tertiary-level care settings with fever, chills, gastrointestinal symptoms, shortness of breath, and chest pain. We present the case of a 46-year-old Caucasian male who presented with lightheadedness, chest pain, and gastrointestinal symptoms after using IV methamphetamine. On physical examination, he was disoriented, tachycardic, and had a fever of 102.8⁰F. He did not have any Osler nodes, Janeway lesions, or splinter hemorrhages. Diagnostics showed leukopenia with neutropenia, lactic acidosis, and elevated creatine kinase. Blood cultures did not grow any organisms. The patient was admitted to the intensive care unit and treated with IV fluids and broad-spectrum antibiotics. His condition improved rapidly and the patient left against medical advice (AMA). The toxic appearance of patients presenting with cotton fever often causes panic among clinicians, resulting in an extensive diagnostic workup, exhaustion of hospital resources, and overprescription of antibiotics. Due to the lack of knowledge about this condition among healthcare practitioners and the tendency of these patients to leave AMA, an appropriate management strategy remains unrecognized. Our case aims to bring awareness about this condition to help guide patient-directed care, reduce the use of healthcare resources, and establish prevention strategies in the community.
