Gonorrhoea: Drug Resistance in Australia

Australian Federation of AIDS Organisations (AFAO), 26 June 2018

There has long been concern globally about the potential emergence of drug resistant STIs. In response, the World Health Organisation released new treatment guidelines for three common STIs – chlamydia, gonorrhoea and syphilis – in 2016.

At present, strains resistant to first line treatment of syphilis and chlamydia are not common and not a concern in Australia. There is, however, a growing level of concern about gonorrhoea. This paper therefore focuses on the likelihood and implications of the emergence of drug resistant cases of gonorrhoea in Australia. It also highlights treatment options in Australia and current and emerging strategies for preventing drug resistant gonorrhoea.

Gonorrhoea ‘super-superbugs’ triple in six months [in Australia]

SMH, 13/02/2018

Cases of a strain of gonorrhoea impervious to an antibiotic have almost tripled in six months, the latest report from the National Alert System for Critical Antimicrobial Resistance (CARAlert) reveals.

The result was a “warning shot across the bow” for doctors and public health officials fighting antibiotic resistance, CARAlert’s senior medical adviser said.

Can you get gonorrhoea from kissing?

ABC Radio (Hack), 8th November 2017

In a troubling development, Melbourne researchers suspect gonorrhoea is being spread by kissing, overturning years of conventional wisdom.

Although it’s early days and not cause for alarm, there is evidence to suggest ‘throat-to-throat transmission’ may be driving the spread of gonorrhea in inner-city Australia.

It’s been generally understood you could only get gonorrhea by having vaginal, anal or oral sex with someone who has gonorrhea. Dr Vincent J Cornelisse, a sexual health physician and PhD candidate at Monash University, has been conducting research that challenges this idea.

Professor Basil Donovan, head of the Sexual Health Program at the Kirby Institute, told Hack the finding was “highly tenuous”. “You’ll need a lot more science before you put out a warning,” he said.

Abstract:

Background: Female sex workers in Australia have achieved some of the lowest documented prevalences of human immunodeficiency virus (HIV) and other sexually transmissible infections globally but rates overall are increasing in Australia and warrant closer investigation.

Methods: We constructed a retrospective cohort using repeat testing data extracted from a network of 42 sexual health clinics. Poisson and Cox regression were used to determined trends in incidence and risk factors for HIV, chlamydia, gonorrhoea, and infectious syphilis among female sex workers.

Results: From 2009 to 2015, 18,475 women reporting sex work attended a participating service. The overall incidence of urogenital chlamydia was 7.7/100 person years (PY), declining by 38% from 2009 to 2013 before increasing by 43% to 2015 (P < 0.001); anorectal chlamydia incidence was 0.6/100 PY, and pharyngeal was 1.9/100 PY, which increased significantly during the study period (P < 0.001, both). For gonorrhoea, the urogenital incidence was 1.4/100 PY, anorectal incidence was 0.3/100 PY, P < 0.001), and 3.6/100 PY for pharyngeal; urogenital incidence doubled during the study period, anorectal increased fivefold, and pharyngeal more than tripled (P < 0.001, all). Incidence of infectious syphilis was 0.4/100 PY, which remained stable from 2009 to 2015 (P = 0.09). There were seven incident infections of HIV among female sex workers (0.1/100 PY). Inconsistent condom use with private partners, higher number of private partner numbers, recent injecting drug use, younger age, and country of birth variously predicted sexually transmissible infections among female sex workers.

Conclusions: Although infectious syphilis and HIV remain uncommon in female sex workers attending Australian sexual health clinics, the increasing incidence of gonorrhoea across anatomical sites and increasing chlamydia after a period of decline demands enhanced health promotion initiatives.

Vaccine for Meningitis Shows Some Protection Against Gonorrhea

New Zealand Family Planning

Some strains of the bacterium that cause gonorrhoea are now resistant to all available antibiotics. With no new drugs on the near horizon, the disease is in desperate need of a vaccine.

Our research, published in the Lancet medical journal this week, shows that protection against gonorrhoea could come from an unexpected source – a vaccine against meningococcal group B disease.

 

 

 

New class of antibiotic raises hopes for urgently-needed gonorrhoea drug

The Guardian, Tuesday 8 August 2017 

A new class of antibiotic has been found to work in the lab against the sexually transmitted infection gonorrhoea, which can cause infertility and damage to babies and is fast becoming resistant to all existing drugs.

Although it is early days, because the antibiotic has yet to be tried in animals or humans, researchers say they are excited by its potential.
