ABSTRACT
Background:
Cotton fever is a self-limited, febrile syndrome occurring after the injection of trace amounts of drugs, in particular heroin, extracted from reused cotton filters. It is characterized by non-specific findings, such as fever, tachycardia, and leucocytosis. The leading pathophysiologic explanation suggests it is the result of direct inoculation of the bloodstream with endotoxins from Gram-negative bacilli of the genus Enterobacter, known to colonize all parts of the cotton plant. Only one prior case report has suggested cotton fever as a potential risk factor of infective endocarditis (IE). Casesummary:
We describe a case of a 57-year-old patient with a history of intravenous heroin use complicated by self-reported episodes of cotton fever. His presentation was notable for Enterobacter cloacae IE with bilateral septic pulmonary emboli. Transthoracic echocardiography findings included new tricuspid regurgitation and two mobile echodensities on the right atrial implantable cardioverter defibrillator (ICD) lead. Despite broad antibiotic coverage and extraction of the ICD leads, the patient passed away from septic shock.Discussion:
The present case report is only the second published report of endocarditis in a patient with a history of cotton fever. In both cases, bacteria of the Enterobacter genus were isolated in patients' blood cultures. This evidence supports the endotoxin theory as the leading pathophysiologic explanation for cotton fever and suggests cotton fever as a risk factor for Gram-negative IE. In the inpatient setting it informs proper antibiotic coverage, whereas in the outpatient setting it supports harm reduction interventions in the form of sterile cotton balls.
