Vancomycin

Last Update: August 20, 2020.

OVERVIEW

Information

Vancomycin is a broad spectrum antibiotic that has activity against methicillin-resistant strains of Staphylococcus aureus and is generally reserved for serious drug resistant gram-positive infections. Vancomycin therapy has been linked many to instances of hypersensitivity with fever, rash and eosinophilia that can be associated with mild hepatic injury, but has only rarely been associated with severe or life-threatening liver injury.

Background

Vancomycin (van" koe mye' sin) is a glycopeptide antibiotic produced by Streptococcus orientalis with primary activity against gram positive bacteria. Vancomycin has a large, complex and unusual structure and is believed to act by inhibition of bacterial cell wall synthesis via binding to the cell wall precursor molecules. Vancomycin is active against, and its major use is in therapy of, infections due to methicillin-resistant Staphylococcus aureus (MRSA), including antibiotic-induced pseudomembranous colitis, staphylococcal enterocolitis, bacterial endocarditis, and sepsis. Vancomycin is not well absorbed orally and for systemic infections it is given intravenously. It is frequently used in combination with other antibiotics and started before bacterial sensitivity results are available. For localized or nonsystemic infections, other routes of administration are used, including oral, rectal, topical, inhalational, intrathecal, intraperitoneal, and intraventricular. The recommended parenteral dosage in adults is 500 mg iv every 6 hours or 1000 mg every 12 hours, with modification to achieve a therapeutic range as needed. The recommended oral dosage in the treatment of antibiotic induced pseudomembranous enterocolitis is 125 to 500 mg every 6 hours for 7 to 10 days. Vancomycin is available generically and under several commercial names including Vancoled, Vancor, Lyphocin, and Vancocin in 125 and 250 mg pulvules and as power for injection or oral administration. Vancomycin was first approved for use in the United States in 1958 and it continues to be widely used, particularly with the recent rise in incidence of serious MRSA infections. Vancomycin is largely well tolerated; common side effects include diarrhea, nausea, nephrotoxicity and neutropenia. Uncommon but potentially severe adverse reactions include infusion reactions, flushing reactions, anaphylaxis, nephrotoxicity, ototoxicity, hypersensitivity reactions including Stevens-Johnson syndrome, and drug reactions with rash, eosinophilia and systemic symptoms (DRESS syndrome).

Hepatotoxicity

Intravenous vancomycin is associated with minor, transient and asymptomatic elevations in serum aminotransferase levels in 1% to 5% of patients, but similar or minimally lower rates of abnormalities are usually reported with comparative agents. In rare instances, the serum enzyme elevations are more marked and may be associated with mild symptoms, although usually without jaundice. In recent years, vancomycin has been linked to hypersensitivity reactions, including Stevens-Johnson syndrome, toxic epidermal necrolysis and the distinctive syndrome of drug reaction, eosinophilia and systemic symptoms (DRESS). These forms of hypersensitivity generally arise within a few days to 3 to 4 weeks after initiation of intravenous (iv) vancomycin therapy. Fever and severe skin rash generally dominate the clinical presentation, but systemic symptoms can include renal, respiratory or heart failure, neutropenia, thrombocytopenia, and liver injury. Cases of DRESS syndrome associated with vancomycin are often accompanied by serum enzyme elevations (Case 1), but marked elevations, symptoms and jaundice are uncommon. The usual systemic features of vancomycin induced DRESS syndrome are renal rather than liver injury but features of hypersensitivity are usually more prominent than organ-specific injury. Nevertheless, in rare instances the liver injury can be severe (Case 2) and result in hepatic failure and death. Patients who receive intravenous vancomycin often have multiple comorbidities including sepsis and receive multiple antibiotics which make the attribution of the hypersensitivity reactions and liver injury with vancomycin difficult. Other more well-known causes of DRESS syndrome include allopurinol, sulfonamides, and the aromatic anticonvulsants. These other causes of DRESS syndrome are more likely to be associated with clinically apparent and even fatal liver injury.

Vancomycin is also associated with several forms of acute infusion reactions, most notably anaphylaxis and the vancomycin flushing reaction, previously known as “red man syndrome”. Vancomycin flushing reactions occur typically during the first 15 to 20 minutes of an initial infusion of vancomycin, most commonly when given rapidly and in relative high doses (1000 mg given over less than 60 minutes). The reaction is characterized by flushing, erythema, and itching usually of the face, neck and upper torso, sometimes accompanied by chest and back pain and variable degrees of hypotension. Rarely, flushing reactions have been associated with oral vancomycin therapy, particularly in elderly patients with active colitis and renal dysfunction. The cause of the symptoms is probably the acute degranulation of mast cells by the direct effect of vancomycin or S. Aureus toxins. The mediator of the reaction is histamine and other active amines or components in mast cell granules. Plasma histamine levels are usually elevated in persons with vancomycin flushing reactions, but the correlation of changes in plasma histamine levels and severity of symptoms is poor. Nevertheless, the symptoms of the vancomycin flushing reaction can be prevented or ameliorated by pretreatment with antihistamines. Perhaps a better approach is the use of slower infusion rates and lower doses of vancomycin. Liver injury is not a feature of vancomycin flushing reactions but can arise secondarily in cases with prolonged or severe hypotension.

Likelihood score: B (highly likely cause of clinically apparent liver injury usually in association with DRESS syndrome).

Mechanism of Injury

Vancomycin is rapidly excreted in the urine without significant hepatic metabolism, which perhaps explains the lack of significant direct hepatotoxicity. Hypersensitivity probably accounts for the instances of mild anicteric hepatitis associated with DRESS syndrome and Stevens-Johnson syndrome due to intravenous vancomycin. Case series have recently shown a close association of vancomycin induced DRESS syndrome with the HLA allele A*32:01, which was detected in 83% of vancomycin induced DRESS syndrome cases but only 6% of population controls. Interestingly, this allele was not associated with cases of Stevens-Johnson syndrome related to vancomycin. The association of ALT elevations and the vancomycin flushing reaction with oral vancomycin is surprising in view of its lack of oral absorption, but the presence of active colitis may allow for some systemic exposure.

Outcome and Management

In published cases, the hepatic injury has usually been self-limited, but rare instances of acute liver failure in the context of hypersensitivity reactions have been linked to vancomycin therapy. Vancomycin should be discontinued promptly in patients who develop immunoallergic features. Corticosteroids are often used to treat the systemic hypersensitivity and relapse may occur when they are discontinued early. In general, spontaneous recovery is usually slow despite early discontinuation of vancomycin, while corticosteroids generally result in rapid resolution. There is no evidence for cross sensitivity to hypersensitivity reactions to vancomycin with other antibiotics, except in some instances for teicoplanin, a vancomycin-like antibiotic available in some countries, but not the United States.

CASE REPORT

Case 1. DRESS Syndrome without jaundice due to intravenous vancomycin therapy.(1)

A 64 year old man with diabetes, severe obesity, hyperlipidemia, asthma and depression developed DRESS syndrome have receiving intravenous vancomycin for an infected hematoma, a complication of bilateral hernia repair. The patient had a long history of obesity and at one point was found to have serum ALT elevations which were attributed to nonalcoholic fatty liver. After bilateral hernia repair operation he developed a local hematoma that became infected and was treated with intravenous vancomycin (1.5 to 2 mg daily) and piperacillin/tazobactam which was discontinued after 5 days and switched to oral ciprofloxacin and metronidazole. After 10 days of vancomycin therapy, he developed fever followed by rash, and vancomycin was discontinued. The rash worsened and he developed evidence of both renal and hepatic injury leading to his admission. A skin biopsy and the presence of eosinophilia supported the diagnosis of DRESS syndrome and he was started on prednisone. Serum ALT levels rose to 1200 U/L with an alkaline phosphatase of 256 U/L and an INR of 1.8, while bilirubin levels increased slightly to a peak of 1.9 mg/dL. Serum creatinine peaked at 1.9 mg/dL. These values had been normal before the onset of DRESS (Table). His rash as well as both renal and hepatic tests began to improve and he was discharged and followed monthly in clinic. At 6 and 9 months after onset, he was asymptomatic, no longer taking prednisone and both liver and kidney tests were all within in normal range.

Comment

This man with diabetes, severe obesity and suspected nonalcoholic fatty liver disease developed DRESS syndrome 2 weeks after starting intravenous vancomycin for a postoperative infection. Despite stopping vancomycin fairly promptly and initiation of corticosteroid therapy a week later, liver tests worsened for another ten days before they began to improve. In follow up, he was able to stop the corticosteroid therapy and liver tests remained normal. As is typical of DRESS syndrome induced by vancomycin, renal dysfunction was also present and also resolved with prednisone therapy and time.

Case 2. DRESS Syndrome with jaundice due to vancomycin therapy.(1)

A 60 year old man with acute bacterial endocarditis due to Staphylococcus aureus was initially treated with intravenous vancomycin and nafcillin. Vancomycin was discontinued after 3 days when sensitivity results showed that the S. aureus was methicillin-sensitive. Two weeks later he developed rash and renal dysfunction that was attributed to nafcillin, which was discontinued and vancomycin restarted. Three weeks later he developed a worsening rash that spread to his entire body accompanied by fever and facial edema. He had recently been started on hydralazine because of hypertension not adequately controlled by metoprolol. Laboratory testing showed marked eosinophilia (16%) and abnormal liver tests with ALT 2018 U/L, AST 1232 U/L, Alk P 343 U/L and bilirubin 1.3 mg/dL. Renal function had worsened and serum creatinine was 6.4 mg/dL. Vancomycin and hydralazine were stopped and he was followed as an outpatient. A few days later his rash was worse and he was admitted for evaluation and therapy. A skin biopsy suggested a drug reaction. Tests for hepatitis A, B and C, Epstein Barr virus and cytomegalovirus were negative as were autoantibodies. Serum immunoglobulins were normal. Hydralazine was stopped and high dose corticosteroids were started. Thereafter, he improved rapidly and prednisone dose was slowly lowered. When seen 3, 5 and 6 months after onset, his liver tests were normal, but he remained on low doses of prednisone.

Comment

This man with bacterial endocarditis developed skin rash that was probably misinterpreted as being due to nafcillin and was restarted on vancomycin, the more likely culprit. Within 3 weeks he had a disseminated rash, fever, marked eosinophilia, worsening renal insufficiency and marked elevations in serum aminotransferase levels at which point vancomycin was discontinued. He became jaundiced and was started on prednisone which improved the symptoms of hypersensitivity. The renal and hepatic abnormalities improved slowly but were back in the normal range within the next few months. Why he was also taking hydralazine, the time to onset and clinical features were not typical of hydralazine induced liver injury. Most instances of DRESS associated with vancomycin arise within 1 to 6 weeks of starting the medication and are associated with mild or minimal hepatic abnormalities and more prominent renal dysfunction. In this instance, the prolonged therapy probably led to a more serious renal and hepatic involvement. While the hepatic abnormalities were associated with jaundice, the degree of hyperbilirubinemia was mild. Despite that, the INR rose to a level above 1.5 indicating that severe liver injury may have been present.
