Neisseria gonorrhoeae is the second most common bacterial cause of sexually transmitted infections STIs in Konjuhgtivitis America, following Chlamydia trachomatis. More recently, cases of resistance to cephalosporins, the current first-line treatment, have been reported.

According to the Public Health Agency of Canada PHACthe incidence of gonorrhea has more than doubled, from approximately 15 cases perin to up to 33 cases perin Gonorrhea is often asymptomatic in females and symptomatic in males. The urethra and gonoree are the most frequently affected anatomical sites, followed by anal and pharyngeal areas.

Gonococcal infections are considered uncomplicated in the absence of bacteremia or pathogen spread to extragenital sites. These include pelvic inflammatory disease, infertility, ectopic pregnancy and chronic pain in women and epididymo-orchitis, reactive arthritis and, rarely, infertility in men. Pharmacists can help their patients by being familiar with symptoms of gonorrhea infections and being aware of new guidelines and treatment regimens Box 1.

When treatment failures are minimized, the potential spread of resistant disease is also reduced. Konjumgtivitis, antibiotic therapy should be effective at all anatomical sites, well tolerated and easy to comply with preferably single-dose therapy at the point of care, i. New recommendations for the treatment of gonorrhea have been published to address the increased prevalence of N. Updated guidelines are also available from British Columbia and Saskatchewan. Treatment guidelines konnungtivitis gonococcal infection in adults 25111220 Drugs of choice in penicillin or cephalosporin-allergic patients 251120 gonkre, The guidelines address the increasing resistance to cephalosporins, konnjungtivitis recommendations varying based on the geographic region.

Canadian guidelines recommend either intramuscular IM ceftriaxone or oral cefixime as the preferred antibiotic of choice. In contrast, the CDC and organizations in other countries advocate only parenteral cephalosporins as konjungtjvitis therapy. Similar to the international guidelines, Ontario also recommends parenteral cephalosporins as the preferred regimen, given local reports of resistance to oral cefixime.

Both Canada and the United States recommend the lower mg dose, while Europe and the UK propose a higher dose of mg. All guidelines currently recommend co-treatment with azithromycin for C.

The reasons for co-treatment include the high rate of coinfection and antigonococcal activity of azithromycin and doxycycline. Each year the program reports rising numbers of gonorrhea cases, with an increasing proportion resistant to at least 1 antibiotic. Between andno reported isolates were resistant to either ceftriaxone or cefixime. However, a shift occurred in the modal minimum inhibitory concentration MIC for both drugs, including a combined total of isolates with decreased susceptibility.

Among these isolates, more exhibited reduced susceptibility to cefixime than to ceftriaxone. The mechanism for resistance was largely due to alterations in the penA, porB1b and mtrR genes, 23 which diminish b-lactam binding to the cell wall, decrease permeability of konjungtivitiis and increase drug efflux from the cell, respectively. A total of 4 isolates with decreased susceptibility MIC of 0.

In3 isolates resistant to cefixime were reported, 2 with MICs of 0. Clinical cases of cephalosporin treatment failures in Canada are only recent.

A retrospective cohort study published in from a Toronto sexual health clinic described treatment failure with cefixime. Nine individuals were reported to have failed cefixime gonord the treatment konjunngtivitis urethral, rectal or pharyngeal gonococcal infections.

The other 4 were not considered treatment failures as their records did not include information as to possible sexual reexposure. In contrast, an Alberta study reported treatment failures in pharyngeal infections with cefixime mg in Prior to this study, most clinical failures were reported internationally.

In Austria in1 case of cefixime failure was reported in an MSM.

In most cases, ceftriaxone was prescribed following identification of the treatment failure. The use of the cephalosporins in the treatment of gonorrhea is a concern, regardless of whether ceftriaxone or cefixime at an elevated dose of mg is used as first-line therapy. Note only does the lack of alternative therapies limit clinicians in tailoring therapies based on safety considerations such as drug allergies, pregnancy and adverse effects, but the focus on one class for therapy has historically led to a rapid rise in resistance.

The newest guidelines address the issue of increasing resistance to the cephalosporins with the knowledge that choices are limited once this class is no longer effective.

The Canadian guidelines are unique, as they continue fonore recommend oral cefixime with an increased dose to overcome rising MICs. The mg dose of cefixime is off-label use; however, the Canadian guidelines state that it is safe and effective and provides a prolonged time above the MIC when compared with the mg dose.

A study compared both the mg and mg doses of cefixime with IM ceftriaxone mg in patients with uncomplicated N. In the 3 cases of treatment failure 1 case with cefixime mg and 2 cases with cefixime mgthe cefixime MIC ranged from 0. Three patients reported adverse effects after taking the mg cefixime dose compared with 10 in the mg group and none in kkonjungtivitis ceftriaxone group.

A randomized unblinded study of patients similarly evaluated oral cefixime mg or mg and ceftriaxone mg IM. Gastrointestinal side effects e. The 6 patients with persistent infection following cefixime therapy had baseline MICs of 0.

The 2 patients with persistent infection following ceftriaxone therapy had baseline MICs of 0. The PHAC recommends consultation with infectious disease specialists along with culture and sensitivity konjungtivotis for cases of treatment failure.

Konjungtivitks includes higher doses of ceftriaxone ranging from mg to 1 g IM given in combination with azithromycin 1 g orally.

Second-line therapy and treatment failure therapy all require a test of cure see Table 3. It is essential that the development of konmungtivitis to N.

Patient education and partner notification are of utmost importance in improving public awareness and reducing the spread of this resistant organism Box 2. Treatment failures 251120 The growing resistance of N. The PHAC continues to recommend oral cefixime but at an increased dose of mg, or IM ceftriaxone, with only the latter recommended for MSM and pharyngeal infections. Guidelines from the province of Ontario, vonore United States and Europe endorse IM ceftriaxone as the sole first-line agent for all gonococcal infections.

Of note, Sanofi-Pasteur has recently announced a nationwide shortage of cefixime predicted to last until October Although provincial public health agencies are reserving cefixime specifically for the treatment of gonococcal infections, supplies may not last until the end of the back order. In response, konjungtivitks public health agencies remain vigilant in monitoring the evolution of this organism and maintaining up-to-date guidelines.
