Substances such as cocaine and metamphetamines, on the other hand, increase systemic afterload, causing increased turbulence at the sites of the aortic and mitral valves. Therefore, any shifts in the incidence of right versus left-sided IE may reflect the availability of certain illicit substances (6, 10). A special subset of endocarditis is that affecting prosthetic valves. This is traditionally divided into early onset (within 60 days of surgery) or late onset.

Patient selection

In IDU patients, IE accounts for 5–20% of hospitalizations and 5–10% of total deaths (4, 5). Furthermore, though nearly half of the respondents felt that infectious diseases providers should actively manage SUDs, only 3% reported having a waiver from the Drug Enforcement Agency (DEA) to prescribe buprenorphine in the outpatient setting. To overcome this barrier, more providers are needed who are willing and able to prescribe buprenorphine.

Proposed Treatment Recommendations

Infective endocarditis (IE) is the infection of the endocardial surface (innermost layer – valves, chordae tendineae, and papillary muscles) of the heart. It usually refers to infection of one or more of the heart valves which may be native or prosthetic. The definition also includes infection on indwelling cardiac devices. Over time, the etiology, as well as causes of IE, have evolved and doubled in numbers because of a greater number of patients with indwelling cardiac devices and central lines.

Infective Endocarditis in Persons Who Use Drugs: Epidemiology, Current Management, and Emerging Treatments

• In endocarditis, irregular growths made of germs and cell pieces form a mass in the heart.
• If you have symptoms of endocarditis, see your health care provider as soon as possible — especially if you have a congenital heart defect or history of endocarditis.
• Streptococcus viridans (eg, S. anguis, S. milleri, S. mutans, S. mitior) make up the normal bacterial flora of the pharynx and upper respiratory tract.
• Physical examination on presentation was significant for temperature of 39.3°C, controlled blood pressure, sinus tachycardia at a rate of 105 beats/min, and a respiratory rate of 28/min.

Infectious diseases providers can play a unique role in the care of SUD in the context of IDU-IE and comparable invasive injection-related infections, such as spinal, bone, joint and severe soft tissue infections, as well as typically chronic infections, such as HIV and viral hepatitis. On the other hand, the long-term outcome of IDA patients is very unsatisfactory, as shown by Rohn et al. [3] but, at least in large part, likely attributable to continuing drug abuse, as suggested by a 2.3 increase in the risk of death at multivariate analysis in our series. Many different things can cause germs to get into the bloodstream and lead to endocarditis. Having a faulty, diseased or damaged heart valve increases the risk of the condition.

• Transthoracic echocardiography should be performed to establish a new baseline.
• “Our study supports that patients with infective endocarditis related to drug use are typically younger, with higher rates of smoking, drinking and liver disease. They are more likely to need emergency surgery, and be on Medicaid or uninsured,” says Dr. Crestanello.
• Due to the nature of the disease that can have an unusual presentation, clinicians should be aware of the variety of presentations a patient with suspected IE could have as disease prognosis relies on a prompt diagnosis.
• He had a past medical history of asthma and polysubstance abuse, on a methadone maintenance program.

• After the relevant surgical procedure, a full course of antibiotic eradication therapy should be administered.
• Coli, Corynebacterium, Proteus mirabilis, Mycobacterium tuberculosis, and Bacteroides fragilis(8).
• The blue arrow is pointing to a large, hyperlucent lesion in the right upper lobe, likely septic emboli.
• If any of these signs occur together with a fever, the patient should be urgently referred to a cardiologist for blood cultures and echocardiography – the level of risk will determine whether this is transesophageal echo (TEE) or transthoracic echo.
• However, the high recurrence rate caused by continuing IDU and medical non-compliance inevitably raises the ethical consideration of offering valve surgery to this patient population.

Bacteria, fungi or other germs get into the bloodstream and attach to damaged areas in the heart. Things that make you more likely to get endocarditis are artificial heart valves, damaged heart valves or other heart defects. If, following blood cultures, the diagnosis is secure, high-dose IV antibiotics should be started immediately. It is becoming increasingly common to insert a tunneled central line to facilitate several weeks of IV treatment without the need for repeated cannulation – with the pain and attendant risk of secondary infection that this incurs.

• If you have endocarditis or any type of congenital heart disease, talk to your dentist and other care providers about your risks and whether you need preventive antibiotics.
• Bacteria, fungi or other germs get into the bloodstream and attach to damaged areas in the heart.
• The lesions, called vegetations, are masses composed of fibrin, platelets, and infecting organisms, held together by agglutinating antibodies produced by the bacteria.
• Transthoracic echocardiography (TTE) obtained on the day of admission did not reveal any detectable intracardiac vegetations.

Multislice computed tomography in infective endocarditis

Initial tests were notable for a urine drug screen positive for cocaine, marijuana, methadone, and opioids. Complete blood count showed mild hemolytic anemia with hemoglobin of 9.2 g/dL, reticulocytosis (2.93%) with normal white blood cell count. The serum lactate dehydrogenase (LDH) was 222U/L, C-reactive protein (CRP) 4.27 mg/dL, erythrocyte sedimentation rate (ESR) 51, and pro-B-type natriuretic peptide (proBNP) 3866 pg/ml. Chest radiograph revealed mixed interstitial and air space disease throughout both lungs. The patient was started on ceftriaxone and azithromycin empirically considering sepsis due to pneumonia. The classic physical findings (Janeway lesions, Osler’s nodes, Roth spots and splinter hemorrhages) are rarely seen, appearing only in 5–15% of IE patients.

Challenges occur after hospital discharge with loss of follow-up and high short-term mortality. In-hospital and community comprehensive addiction management may improve these patients’ outcomes beyond the surgical procedure. There has been a continuous debate as to whether it is ethical to withhold valve surgery in an active, noncompliant drug user.

Chambers and valves of the heart

It is usually absent on patients started on antibiotics, antipyretics, elderly patients, with heart failure or renal failure. The disease itself had been known to have unusual and non-specific presentations with case reports citing neuropsychiatric manifestations such as symptoms of transient ischemic attack iv drug use (TIA) or stroke, seizures, or agitation [4]. Empirical treatment of endocarditis affecting prosthetic valves should cover streptococci, enterococci, staphylococci (including methicillin-resistant S. aureus), and Gram-negative organisms. Vancomycin or teicoplanin with gentamicin have good synergistic cover.
