Risk of Staph Infections may be Reduced by Nasal Ointment

A review of several studies has revealed that a nasal antibiotic ointment can reduce the risk of staph infection without causing antibiotic resistance.

Miranda van Rijen, the lead review author and an infection control practitioner at Amphia Hospital Breda in the Netherlands, suggests that of intranasal mupirocin can lower the infection rate in hospitalized patients, who test positive as nasal carriers of the Staphylococcus aureus bacteria,

Pneumonia - Causes, Symptoms, Diagnosis, Treatment, Prevention, Complications
Pneumonia is a lung infection that can be caused by a bacteria or a virus. It causes inflammation of the alveoli or the air sacs of the lungs.

Up to 30 percent of people are nasal carriers of staph aureus, which simply means they carry the bacteria in their nostrils but it does not cause an infection. Most of the time, staph causes no infection or involves only minor skin problems. However, it can sometimes lead to serious complications.

Mupirocin, also known by its brand name, Bactroban is a topical antibiotic that is effective against several bacteria, including methicillin-resistant Staphylococcus aureus (MRSA).

The drug works by blocking the activity of an enzyme within bacteria.

Hib Vaccine - Types, Dosage Schedule, Contraindications and Side Effects
The Hib vaccine protects children against infections like meningitis and pneumonia that are caused by the Haemophilus influenzae type b bacterium.

During the study, the researchers reviewed nine randomized controlled trials involving 3,396 patients who were nasal carriers of staph aureus.

They found that patients who received intranasal mupirocin had about half the rates of staph infection after treatment, compared to patients who received no treatment or a placebo.

Respiratory Diseases - Diseases of the Human Respiratory System
Respiratory diseases affect any part of the respiratory system. Some of the lung diseases like chronic obstructive pulmonary disease can lead to respiratory failure.

Staph infections can cause significant complications in hospitalized patients: pneumonia, surgical wound infections, urinary tract infections and blood-borne bacterial infections.

"We were not surprised by the results," van Rijen said.

Lung Biopsy - Indications - Procedures - Risks - FAQs - Reference
The procedure by which tissue samples are obtained from the lung is known as lung biopsy. The biopsy tissues obtained from the lungs are examined by a pathologist.

"In our hospital, mupirocin has been used routinely in cardiothoracic surgery for several years and our S. aureus infection rate is very low," she added.

Until now, "routine use of mupirocin has not been applied in many hospitals, mainly due to concern about the development of mupirocin resistance and the absence of convincing evidence that mupirocin reduces the infection rate," van Rijen said.

"If the 'short-term use' meant five days of therapy for every patient in a hospital - or even every surgical patient in a hospital where the average stay was three days - then a large portion of the constantly changing inpatient population would be on mupirocin therapy," said Barry Farr, M.D., professor emeritus of medicine and epidemiology at the University of Virginia.

The review appears in the latest issue of The Cochrane Library, a publication of The Cochrane Collaboration.
