Why does vancomycin cause red man syndrome




















VFS is a rate-related anaphylactoid adverse reaction which most often occurs during the first exposure to intravenous vancomycin. The prognosis for patients with VFS is excellent with appropriate management. Vancomycin may be used again after an episode of VFS. Appropriate precautions and treatment guidelines should be followed. Normal intravenous saline should be used to treat hypotension, and other supportive care measures should be provided.

Vancomycin flushing syndrome VFS is caused by the release of histamine from basophils and mast cells by antibiotics such as vancomycin. Symptoms include a red rash, hypotension, tachycardia, angioedema, etc. Although most of the cases are manageable, some can be life-threatening. Healthcare providers should be made aware of the presentation of vancomycin flushing syndrome VFS as well as the management of this condition to improve patient outcomes. Patients should be provided with the most appropriate care and educated on the condition.

The rash associated with red man syndrome typically appears during or shortly after vancomycin infusion.

Once symptoms develop, red man syndrome typically lasts about 20 minutes. In some cases, it may last for several hours. If you experience red man syndrome, your doctor will stop vancomycin treatment immediately. They will give you an oral dose of an antihistamine to help manage your symptoms. In more severe cases, such as those involving hypotension, you may need IV fluids, corticosteroids, or both. Your doctor will wait for your symptoms to improve before resuming your vancomycin treatment.

Red man syndrome most often occurs when vancomycin is infused too quickly, but it can occur when the drug is given by other routes as well. The most common symptom is the intense red rash that develops on the upper body, along with an itching or burning sensation. Symptoms generally last a short time and can be managed with antihistamines. Empty sella syndrome is a rare condition that affects the skull.

We'll explain the underlying causes and what you can do to treat them. Most canker sores heal on their own within a couple of weeks. But if you want to speed up the process, here's how. A canker sore on your tonsil can be surprisingly painful. We'll go over common symptoms, treatment options, and home remedies for relief.

The absolute neutrophil count ANC was decreasing and she was getting worse. Cefepime was changed for imipenem mg q6h IV and her prosthesis was removed. On day 10 of vancomycin treatment she reported a rash on her body and on the next day she was sleepy. Neutropenia and thrombocitopenia were noticed. Vancomycin and imipenem were changed for levofloxacin mg qd IV. Four days after discontinuing vancomycin she was better; her condition improved and she was discharged. No other drugs, except for acetaminophen, were used during this period.

Adverse reactions to antibiotics are a common occurrence in hospitalized patients. Vancomycin is often prescribed for methicillin-resistant staphylococcal infections and acute hypersensitivity reactions to this drug have been described, consisting of flushing and pruritus, occasionally accompanied by hypotension "red man syndrome". The onset may occur within a few minutes and usually resolves over several hours, after completion of the infusion. It is often mistaken for an allergic or anaphylactoid reaction, but patients usually tolerate subsequent doses if the dilution and the period of infusion are increased.

Vancomycin is one of the drugs that have the ability to directly release histamine from mast cells by nonimmunological processes. This has been demonstrated in vitro on normal human tissue and in volunteer subjects, in whom it was observed a correlation between histamine levels and symptoms.

The red man syndrome is most likely a consequence of this vancomycin-associated histamine release. In some instances, vancomycin produces immunologically mediated adverse reactions such as interstitial nephritis, lacrimation and linear IgA bullous dermatosis [1], exfoliative erythroderma, necrotizing cutaneous vasculitis and toxic epidermal necrolysis [6].

Isolated reports of vancomycin-associated neutropenia are found in the medical literature, as well as cases of agranulocytosis, thrombocytopenia [4], and only 2 cases of Stevens-Johnson syndrome [5,6]. This was thought to be related to impurities in the drug formulation and newer methods of preparing this antibiotic were developed in order to avoid such a problem.

This usually occurs in the absence of other symptoms or signs of drug toxicity and the interval till the onset of the neutropenia ranges from 9 to 30 days. Rapid and complete recovery of the patient's white blood cell count ensues once the vancomycin was discontinued. The cause of this reaction is still unclear. Nevertheless, bone marrow suppression is not thought to be the mechanism responsible because examination of bone marrow biopsy specimens from patients with this adverse effect has shown both hypoplasia and hyperplasia of the granulocyte series.

A peripheral destructive effect of vancomycin might play a role in reducing the neutrophil count, but again there is conflicting evidence in the literature [7]. It has been postulated that an immunologically mediated mechanism is responsible for reactions to vancomycin and the finding of vancomycin-dependent antibodies to the patients' neutrophils supports this theory. Weitzman et al. Detected serum opsonizing antineutrophil antibodies in 3 patients receiving vancomycin plus a cephalosporin; however, this was not confirmed in 2 different assays.

Adrouny et al. Reported a case of agranulocytosis caused by vancomycin and they proposed a hypersensivity-mediated mechanism as a cause of neutrophil destruction, because of reports of associated rashes and eosinophilia.

Isolated cases of vancomycin-induced thrombocytopenia have been reported and the mechanism is probably related to immunological destruction, as strongly suggested by its association with a drug-dependent antiplatelet antibody [4].
