BACKGROUND: Expedited partner therapy (EPT) for Chlamydia trachomatis (Ct) is the practice of providing Ct-infected patients with medication, or prescription (prescription-EPT) to deliver to their sex partners without first examining those partners. New York City (NYC) providers commonly use prescription-EPT, yet NYC pharmacists report only occasional receipt of EPT prescriptions. This project assessed the frequency of EPT prescriptions filled in 2 NYC neighborhoods. METHODS: The 2 NYC facilities reporting the most frequent use of prescription-EPT were identified from Ct provider case reports and contacted to ascertain their EPT practices...

Resistance of Neisseria gonorrhoeae to azithromycin and ceftriaxone has been increasing in the past years. This is of concern since the combination of these antimicrobials is recommended as the first-line treatment option in most guidelines. To analyse trends in antimicrobial resistance, we retrospectively selected all consultations with a positive N. gonorrhoeae culture at the sexually transmitted infection clinic, Amsterdam, the Netherlands, from January 2012 through September 2015. Minimum inhibitory concentrations (MICs) for azithromycin and ceftriaxone were analysed per year, and determinants associated with decreased susceptibility to azithromycin (MIC > 0...

BACKGROUND: Survival after lung transplantation is hampered by chronic lung allograft dysfunction (CLAD). Persistently elevated BAL-neutrophilia is observed in some patients despite treatment with azithromycin, which may be induced by IL-1α. Our aim is to establish an in vitro model, assess mechanistic pathways and test different therapeutic strategies of IL-1α induced release of IL-8 by human bronchial epithelial cells. METHODS: Bronchial epithelial cells (16HBE) were stimulated with IL-1α with or without azithromycin or dexamethasone...

BACKGROUND: Yaws is a treponemal infection that was almost eradicated fifty years ago; however, the disease has re-emerged in a number of countries including Ghana. A single-dose of intramuscular benzathine penicillin has been the mainstay of treatment for yaws. However, intramuscular injections are painful and pose safety and logistical constraints in the poor areas where yaws occurs. A single center randomized control trial (RCT) carried out in Papua New Guinea in 2012 demonstrated the efficacy of a single-dose of oral azithromycin for the treatment of yaws...

OBJECTIVES: The current treatment options for patients with community-acquired pneumonia (CAP) often present a trade-off between the potential for treatment failure and safety concerns. We set out to investigate real-world outcomes associated with the use of currently available antimicrobial treatment options for CAP in both the outpatient and inpatient (non-intensive care unit [ICU]) settings. METHODS: This claims-based retrospective study included adult patients diagnosed with CAP and treated with antibiotic therapies, including any oral fluoroquinolone, macrolide, or beta-lactam monotherapy in the outpatient setting, and intravenous (IV) levofloxacin or IV azithromycin/ceftriaxone in the inpatient setting...

BACKGROUND: Rectal infection with Chlamydia trachomatis is one of the most common bacterial sexually transmissible infections among men who have sex with men (MSM) with diagnosis rates continuing to rise. Current treatment guidelines recommend either azithromycin 1 g single dose or doxycycline 100 mg twice daily for 7 days. However, there are increasing concerns about treatment failure with azithromycin. We are conducting the first randomised controlled trial (RCT) to compare treatment efficacy of azithromycin versus doxycycline for the treatment of rectal chlamydia in MSM...

In Germany, the reported syphilis prevalence has increased continuously since 2010, with a total of 6834 syphilis cases being reported in 2015. The largest increase of reported syphilis occurred in men who have sex with men (MSM). The antibiotic agent of choice for treatment of syphilis is still penicillin. There are no penicillin-resistant Treponema pallidum strains. Alternatives are ceftriaxone and doxycycline. In Germany, azithromycin is not approved for treatment of syphilis; however, therapy failures are increasingly reported...

Spinal cord injury (SCI) triggers a heterogeneous macrophage response that when experimentally polarized toward alternative forms of activation (M2 macrophages) promotes tissue and functional recovery. There are limited pharmacological therapies that can drive this reparative inflammatory state. In the current study, we used in vitro systems to comprehensively defined markers of macrophages with known pathological (M1) and reparative (M2) properties in SCI. We then used these markers to objectively define the macrophage activation states after SCI in response to delayed azithromycin treatment...

The FDA has updated azithromycin package labeling to include the risk of prolonged cardiac repolarization and QT prolongation, which increase the possibility of cardiac dysrhythmias and torsades de pointes, especially in older adults. The update was initiated by a study that found an increased risk of death in patients taking azithromycin compared with those taking amoxicillin. However, cardiovascular results of other azithromycin studies have demonstrated discordant results, and more research is needed. In the meantime, providers should recognize that azithromycin has a role in the management of bacterial infections and should prescribe the antibiotic when warranted...

Pseudomonas aeruginosa is a multifaceted pathogen causing a variety of biofilm-mediated infections including catheter-associated urinary tract infections (CAUTIs). High prevalence of CAUTIs in hospitals, their clinical manifestations like urethritis, cystitis, pyelonephritis, meningitis, urosepsis, death; and economic challenges underscore the need for management of these infections. Biomaterial modification of urinary catheters with dual drugs seems an interesting approach to combat CAUTIs by inhibiting biofilm...
