Efbemalenograstim alfa-vuxw (Ryzneuta – Evive), a
nonpegylated granulocyte colony-stimulating factor
(G-CSF) conjugated to an Fc fragment of human
IgG2, has been approved by the FDA to decrease
the incidence of infection, as manifested by febrile
neutropenia, in adults with nonmyeloid malignancies
receiving myelosuppressive chemotherapy that can
cause clinically significant febrile neutropenia. It is
the first nonpegylated, long-acting G-CSF to become
available in the US. Two pegylated, long-acting
G-CSFs, pegfilgrastim (Neulasta, and biosimilars)
and eflapegrastim (Rolvedon), are also available.

Since 2007, antimicrobial prophylaxis for dental
procedures has been recommended to prevent
viridans group streptococcal infective endocarditis
only for patients at highest risk of an adverse

appear to have led to an increased incidence of
infective endocarditis or increased mortality due to
infective endocarditis.

Bacterial infections in adults are generally treated
empirically, with the antibiotic covering most, but not
all, of the potential causative pathogens. For some
infections, culture and sensitivity testing can guide
treatment, allowing for use of narrower-spectrum
antibiotics. The recommended dosages and durations
of antibiotic treatment for common respiratory, skin, and
urinary tract infections are listed in Tables 1-3. Infectious
disease experts now recommend shorter treatment
durations for many infections to reduce the development
of antimicrobial resistance and minimize adverse effects.

In Brief: FDA Azithromycin Warning
The Medical Letter on Drugs and Therapeutics • April 1, 2013; (Issue 1413)
The FDA has announced that it is requiring changes in the labeling of the macrolide antibiotic azithromycin (Zithromax, Zmax) to warn about the risk of QT prolongation and cardiac arrhythmias.1 The new warnings...
The FDA has announced that it is requiring changes in the labeling of the macrolide antibiotic azithromycin (Zithromax, Zmax) to warn about the risk of QT prolongation and cardiac arrhythmias.1 The new warnings are based on a retrospective study in The New England Journal of Medicine (reviewed previously in The Medical Letter2), which found that among patients who received 347,795 prescriptions for azithromycin, there were 29 cardiovascular deaths, a significantly higher rate than the 42 that occurred among patients who received 1,348,672 prescriptions for amoxicillin (which does not prolong the QT interval) or the 41 that occurred among 1,391,180 patients who took no antibiotics. The risk with azithromycin was much higher in patients with cardiovascular risk factors.3
Other macrolides and fluoroquinolones can also prolong the QT interval. In the retrospective study, the risk of cardiovascular death with levofloxacin was not significantly different from the risk with azithromycin. As with any retrospective study, the possibility that baseline differences between patients taking azithromycin and those taking other or no antimicrobials could have been responsible for the difference in cardiovascular outcomes cannot be entirely ruled out.

In Brief: Safety of Azithromycin

Recently published results of a large, carefully conducted retrospective study indicated that use of the antibiotic azithromycin (Zithromax, and others) may increase the risk of cardiovascular death, especially in patients with a high baseline risk of cardiovascular disease.1 One possible mechanism is prolongation of the QT interval, which is known to occur rarely with azithromycin and more frequently with the other macrolide antibiotics erythromycin (Erythrocin, and others) and clarithromycin (Biaxin, and others).
Among the patients who received 347,795 prescriptions for azithromycin, there were 29 cardiovascular deaths, a significantly higher rate than the 42 that occurred among the patients who received 1,348,672 prescriptions for amoxicillin (which does not prolong the QT interval) or the 41 that occurred among the 1,391,180 patients who took no antibiotics. Among patients with the highest baseline risk of cardiovascular disease, treatment with azithromycin, compared to amoxicillin, would have resulted in 245 additional cardiovascular deaths per million courses of the antibiotic.
As with any retrospective study, there could have been some undetected differences between the patients who received one drug or the other, but use of an appropriate non-macrolide alternative2 instead of azithromycin might be reasonable in patients with cardiovascular disease or in those who are taking other drugs that can prolong the QT interval (www.azcert.org).

The CDC recently reported that fluoroquinoloneresistant strains of Neisseria meningitidis have been detected for the first time in the US in an area around the border of North Dakota and Minnesota (CDC. MMWR, Feb 22, 2008). These isolates were all serogroup B, for which meningococcal vaccines (Med Lett Drugs Ther 2005; 47:29) do not offer protection. Since many laboratories do not test N. meningitidis for antimicrobial susceptibility, it is possible that such resistance is more widespread.
A single oral dose of ciprofloxacin (Cipro, and others) 500 mg has been used for prophylaxis after close contact with infected patients. Oral rifampin (Rifadin, and others) 600 mg (10 mg/kg for children) q12h for 2 days, a single IM injection of ceftriaxone (Rocephin, and others) 250 mg (125 mg for children), or a single oral dose of azithromycin (Zithromax, and others) 500 mg (10 mg/kg for children) are reasonable alternatives.

On page 100 of the article "Major Changes in Endocarditis Prophylaxis for Dental, GI and GU Procedures", under the section Highest-Risk Procedures, the word "rubber" should have been omitted. Placement of orthodontic rubber bands is not a highest-risk procedure that justifies prophylaxis; placement of orthodontic (metal) bands is. An orthodontic band is a metal ring that surrounds the tooth and is pressed into place causing movement in closely-spaced teeth and sometimes bleeding when the bands are placed close to the gumline.
Major Changes in Endocarditis Prophylaxis for Dental, GI and GU Procedures

The American Heart Association has issued its revised guidelines for prevention of infective endocarditis. Antimicrobial prophylaxis for dental procedures is now recommended only for patients at the highest risk of severe consequences from endocarditis who are undergoing the highest-risk procedures. Endocarditis prophylaxis is no longer recommended for gastrointestinal (GI) and genitourinary (GU) procedures. When these changes are implemented, the number of patients receiving antimicrobial prophylaxis to prevent endocarditis should decline sharply.

Lyme disease in North America is caused by the spirochete Borrelia burgdorferi, which is transmitted to humans by Ixodes scapularis or pacificus ticks. These ticks may also carry other pathogens; coinfection with Babesia microti or Anaplasma phagocytophilum (formerly Ehrlichia) has been reported.1 In 2001 and 2002, 12 states (CT, DE, ME, MD, MA, MI, NH, NJ, NY, PA, RI, WI) reported about 95% of all the Lyme disease in the US, but cases occurred in all states except HI, MT and OK. Most Lyme disease in North America occurs between May and September.

Combination antiretroviral therapy including protease inhibitors has dramatically changed the treatment of HIV infection and the prognosis of those affected (Medical Letter Handbook of Antimicrobial Therapy, 1998, page 122). Due to limitations and failures with these drugs in many patients, however, three new drugs, none of them protease inhibitors, have rapidly come into wide use in clinical trials or 'expanded access' programs. They are abacavir (Ziagen - Glaxo Wellcome), adefovir (Preveon - Gilead) and efavirenz (Sustiva - DuPont). Efavirenz was recently approved for treatment of adults and children by the FDA. Abacavir has been recommended for approval by an FDA advisory committee.
