Cotton Fever: Does the Patient Know Best?

Mucocutaneous Manifestations of Recreational Drug Use

Recreational drug use is increasingly common in the dermatology patient population and is often associated with both general and specific mucocutaneous manifestations. Signs of substance use disorder may include changes to general appearance, skin, and mucosal findings associated with particular routes of drug administration (injection, insufflation, or inhalation) or findings specific to a particular drug. In this review article, we provide an overview of the mucocutaneous manifestations of illicit drug use including cocaine, methamphetamine, heroin, hallucinogens, marijuana, and common adulterants to facilitate the identification and improved care of these patients with the goal being to connect this patient population with appropriate resources for treatment.

Medical Complications of Injection Drug Use - Part II

Medical Complications of Injection Drug Use - Part IIDuring the past 2 decades, the risk of death, as well as the prevalence of hospitalizations in the United States, has increased substantially among people who inject drugs, mainly because of the opioid epidemic. In Part Two of this two-part review, the authors review complications observed in people who inject drugs and strategies to reduce harm.

A case report of Enterobacter cloacae endocarditis in a patient with a history of cotton fever

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).

Case summary

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.

Correlates of Self-Reported Cotton Fever Experience among People Who Inject Opioids

Background: Cotton fever is a febrile syndrome occurring after intravenous drug injection. Although its clinical presentation is well described in the literature, data regarding prevention is lacking. We aimed to assess proportion and correlates of cotton fever experience among people who inject opioids. Methods: We performed a cross-sectional study using data from the community-based survey PrebupIV conducted in France in 2015 among 557 people who regularly injected opioids. Self-reported sociodemographic data, together with data on substance use, injecting practices and occurrence of cotton fever were all collected through face-to-face (n = 398) or online (n = 159) questionnaires. Factors associated with cotton fever experience were assessed using logistic regression model. Results: Over half of the participants (54%) reported cotton fever experience. In the multivariable logistic regression, crack cocaine injection (adjusted Odds Ratio (aOR) = 1.96, 95% Confidence Interval (CI) = 1.03-3.63), longer duration of opioid use (for 1 year of use: aOR = 1.05, 95%CI = 1.02-1.09), and filtering mainly with cotton filters (compared with membrane filters, aOR = 1.86, 95%CI = 1.24-2.78) were all associated with cotton fever experience. Conclusions: Our findings highlight that cotton fever is a frequent complication of injecting drug use. Avoiding the use and reuse of cotton balls to filter injected solutions, and promoting membrane filters use could reduce the risk of the condition occurring.

Cotton fever resulting in Enterobacter asburiae endocarditis

•

Cotton fever is a self-limited phenomenon that occurs in IV drug users.

•

Colloquially known to IV drug users, cotton shooting can cause cotton fever.

•

Enterobacter asburiae endocarditis is a rare complication of cotton fever.

“Cotton fever” is described as a self-limiting illness following “cotton shooting,” the practice of injecting residual drugs extracted from previously used cotton filters. Cases of related Enterobacter agglomerans bacteremia have been described. We report the first described case of cotton fever in a patient resulting in Enterobacter asburiae endocarditis.
