National Shortage of Key Syphilis Drug
|
A national shortage of penicillin G benzathine, the recommended  treatment for syphilis and the only treatment for pregnant women, is another example of the precariousness of drug manufacturing in the U.S. In this case, Pfizer is the sole manufacturer, which leaves no other pharmaceutical company able to produce the drug to address the shortage. Pfizer anticipates the shortage being resolved in July. The CDC recently issued recommendations for clinicians to refrain from using penicillin G benzathine to treat other infections if other effective treatments are available, and to continue to adhere to the recommended dosing regimen of 2.4 million units of penicillin G benzathine to treat primary, secondary, and early latent syphilis. For more information about treating syphilis, refer to the 2015 STD Treatment Guidelines.

 The CDC and the American Sexually Transmitted Diseases Association will host a webinar on Thursday, June 2 from 1:00 - 2:00 pm (ET). "A Journey through Syphilis: How does Treponema pallidum cause such a complex disease?" is the latest in the STD Prevention Science Series. Dr. Sheila Lukehart of the University of Washington will discuss how the host's immune system and bacteria interact, and their implications for syphilis control. Participants join the webinar by clicking here at 1:00 pm on June 2 and calling 800-619-7490.

Updated CDC Fact Sheet on Oral Sex and Risk of HIV, STDs
|
 A newly updated CDC fact sheet outlines the risks of acquiring HIV and STDs from oral sex. The risk of acquiring HIV from oral sex is very low. However, other STDs, such as syphilis, herpes, gonorrhea, and chlamydia, can be acquired from oral sex, and hepatitis A and B, bacteria such as E.coli, and intestinal parasites can be transmitted during mouth-to-anus oral sex. The key message is that transmission of STDs and other infectious organisms can occur during oral sex and use of condoms or dental dams reduces that risk.

New Study Suggests Treatment is Driving Spread of Drug Resistant Gonorrhea
|
A new modeling study published in PLOS Pathogens suggests drug resistant gonorrhea is spreading due to screening and treatment of infected persons. The researchers used data from two antibiotic resistance surveillance systems (one in the U.S. and the other in  England and Wales) to estimate the speed by which resistant strains of gonorrhea spread among men who have sex with men (MSM) and heterosexual men. They also obtained data on the prevalence and incidence of gonorrheal infection, and on sexual behavior among MSM and heterosexual men and women. This data was collectively used to model the spread of antibiotic resistant gonorrheal infection among MSM and heterosexual men. The model predicted a faster spread of resistance among MSM, but not due to MSM having more sexual partners, but instead to their higher level of antibiotic treatment compared to heterosexual men and women.
