Important health information for men who have sex with men

April is STD awareness month: Good health means getting tested

Posted on by

If you are sexually active, getting tested for STDs is one of the most important things you can do to protect your health. Make sure you have an open and honest conversation about your sexual history and STD testing with your doctor and ask whether you should be tested for STDs. If you are not comfortable talking with your regular health care provider about STDs, there are many clinics that provide confidential and free or low-cost testing.

Below is a brief overview of STD testing recommendations. STD screening information for healthcare providers can be found here.

  • All adults and adolescents from ages 13 to 64 should be tested at least once for HIV.
  • All sexually active women younger than 25 years should be tested for gonorrhea and chlamydia every year. Women 25 years and older with risk factors such as new or multiple sex partners or a sex partner who has an STD should also be tested for gonorrhea and chlamydia every year.
  • All pregnant women should be tested for syphilis, HIV, and hepatitis B starting early in pregnancy. At-risk pregnant women should also be tested for chlamydia and gonorrhea starting early in pregnancy. Testing should be repeated as needed to protect the health of mothers and their infants.
  • All sexually active gay and bisexual men should be tested at least once a year for syphilis, chlamydia, and gonorrhea. Those who have multiple or anonymous partners should be tested more frequently for STDs (i.e., at 3- to 6-month intervals).
  • Sexually active gay and bisexual men may benefit from more frequent HIV testing (e.g., every 3 to 6 months).
  • Anyone who has unsafe sex or shares injection drug equipment should get tested for HIV at least once a year.

New STDs emerging

Posted on by

From the New York Daily News…

The first worrisome pathogen is Neisseria meningitides, a bacteria that “can cause invasive meningitis, a potentially deadly infection of the brain and spinal cord’s protective membranes,” the health website Mosaic informs us. “More commonly, it’s gaining a reputation as a cause of urogenital infections.”

N meningitides resides in the back of the nose and throat of between 5% and 10% of adults, the site said. There’s a chance people can transmit the bacteria via oral sex or deep kissing.

In 2015, Mosaic said, the bacterial strain mixed with the closely related N gonorrhoeae, which causes gonorrhea — a mutation that allowed the disease to spread more readily.

On the upside, vaccines are available that can protect against all five strains of the gonorrhea bacterium.

Second on the list is Mycoplasma genitalium, one of the world’s smallest bacteria. Between 1% and 2% of people are infected, most of them teens and young adults. Many times it doesn’t cause symptoms, but it can irritate the urethra and cervix, just as gonorrhea and chlamydia do. In women this can lead, like chlamydia, to pelvic inflammatory disease and its associated potential for infertility, miscarriage, premature birth and stillbirth.

While antibiotics exist that will eradicate it, resistant strains are developing, which means it could morph into a superbug.

Third on the list is Shigella flexneri, which one contracts from feces. Shigellosis is one of the bacteria causing dysentery, so is not exclusively contracted via sexual contact. But it might have found a new avenue in anal-oral sex, reported Medscape and the CDC. And given that it is becoming resistant to azithromycin, which also treats gonorrhea, the potential for a superbug is there.

Lymphogranuloma venereum (LGV) is number four on the emerging-STD list, caused by acute Chlamydia trachomatis strains. Its incidence is increasing in Europe and North America, especially among gay and bisexual men, Mosaic reports. A 2016 CDC report documented a cluster of cases among men having sex with men in Michigan. Its symptoms can be subtle, with a fast-disappearing lesion in the genital area, but they can also be even less noticeable, according to the CDC.

Historic Increase in Syphilis Infections

Posted on by

The Pennsylvania Department of Health is reporting an historic increase in the number of new Syphilis infections in the state.

The Health Department is asking anyone who fits the criteria listed here to have a Syphilis test…

  • A rash on the palms of the hands or on the soles of the feet, back, chest, or stomach
  • A lesion (red sore) in the genital, rectal, or oral area
  • Moist papules in the mouth
  • Sudden scalp alopecia (loss of hair)
  • Sudden loss of eyelashes and eyebrows
  • Swelling of the lymph nodes
  • A recent positive test for another STD such as gonorrhea, chlamydia, HIV or Hepatitis C

Send your zip code to m4mInformation@pitt.edu and we’ll send you locations for STD testing. Most are free.

Syphilis is a sexually transmitted infection. If it goes untreated, it can lead to serious health problems including paralysis, blindness, and dementia. However, Syphilis is 100% curable with simple antibiotics.

Syphilis is spread through direct contact with a Syphilis sore during vaginal, anal, or oral sex. You can get Syphilis and not have any symptoms so the only way to know for sure you’re not infected is to get tested.

Several locations around the state have free Syphilis testing. Click on this link to find free testing at a State Health Center near you.

Health Alert: Post-Exposure Prophylaxis for HIV (not to be confused with PrEP)

Posted on by

From redorbit.com…

Post-exposure prophylaxis (PEP) involves taking of Anti-Retroviral Therapy (ART) drugs after potential exposure to HIV infection. This is an emergency HIV treatment usually received within 72 hours after the possible exposure. This should be confused as a cure for HIV but rather a form of preventing infection. It is, in fact, a short course of ARV drugs to stop the exposure to HIV from progressing into a life-threatening condition.

Some facts about PEP:

  • Taking PEP can result in an array of side effects including fatigue and nausea, but it is advisable not to stop taking the medication, instead consult your healthcare provider.
  • The emergency treatment should be started as soon as possible to guarantee its effectiveness. That means, it should be less 72 hours after exposure to the virus.
  • PEP is prescribed by your doctor to be taken daily at the same time for up to 4 weeks. This is according to the World Health Organization’s guideline on PEP use.

Health Alert: Rates of STDs climbed for the fourth consecutive year in the US

Posted on by

Rates of syphilis, gonorrhea and chlamydia have climbed for the fourth consecutive year in the United States, the Centers for Disease Control and Prevention (DCD) announced recently. Last year, nearly 2.3 million US cases of sexually transmitted diseases (STDs) were diagnosed, which is the highest number ever reported.

Chlamydia, which remained the most common, is easily transmitted during any form of sexual activity. If not treated, chlamydia can cause permanent damage to the reproductive system. In men, the infection can spread to the tube that carries sperm from the testicles, causing pain and fever.

If not treated, gonorrhea can cause severe and permanent health issues, including problems with the prostate and testicles in men or problems with pregnancy and infertility in women. Gonorrhea is also typically treated with antibiotics but the threat of antibiotic-resistant gonorrhea persists nationwide. 

Syphilis can affect the heart, nervous system and other organs if left untreated. Syphilis is most often transmitted through sexual contact and is 100 percent curable with antibiotics.

Gonorrhea and chlamydia can infect other sites of the body such as the rectum and the throat and diagnosis requires a swab of each site. A urine test alone is not sufficient to diagnose STDs of the throat and the rectum. Additionally, all of these infections can be transmitted through unprotected oral sex.

It is important to remember that even if you don’t have symptoms, you can still be infected. If you’re sexually active, you should get tested for a full range of STDs, including the ones listed here. Don’t be shy about asking your doctor for a full screening. If you need to find free, confidential testing in your area, you can check the PA Department of Health listing here.

Why STDs are on the rise in America

Posted on by

From the Economist online…

Much of the increase in STDs has come from gay and bisexual men. Although a relatively small share of the population, they accounted for 81% of male syphilis cases in 2016, according to the Centres for Disease Control. As with heterosexuals, this seems to be because sex is now seen as less risky. That is due to the advent of PrEP, a prophylactic drug cocktail which gay men can take to nearly inoculate themselves from HIV. The reduced chances of catching HIV—along with the fact that a positive diagnosis is no longer a death sentence—seems to encourage men to drop their guard. A recent study of gay and bisexual men, published in the Lancet, a medical journal, found that as more began taking PrEP, rates of consistent condom usage dropped from 46% to 31%. Recent studies have shown that uptake of PrEP is strongly associated with increased rates of STD infection.

All this shows that changing sexual mores, and a reduced fear of the risks of unprotected sex, seem to be at fault—especially since the problem is not just limited to America. England experienced a 20% increase in syphilis diagnoses in 2017 and a 22% increase in those of gonorrhoea. Other countries in western Europe have seen ever worse outbreaks, sometimes exceeding 50%. Dwindling public spending on STD prevention—which in America has fallen by 40% in real terms since 2003—is not helping matters. Yet the chief methods of prevention, abstinence and condoms, are tried and true. Should these options seem too chaste or chaffing, then prospective partners ought to get an STD test (especially since most infections can be cleared up with a simple course of antibiotics). Verified testing is vital since verbal assurances, especially on the cusp of a liaison, can be misleading.

Does PrEP use lead to higher STI rates among gay and bi men?

Posted on by

From POZ.com…

Rates of new sexually transmitted infections (STIs) are much higher among men who have sex with men (MSM) taking Truvada (tenofovir disoproxil fumarate/emtricitabine) as pre-exposure prophylaxis (PrEP) than among other MSM. More research is needed, however, to determine whether starting PrEP leads to higher STI rates among MSM.

Publishing their findings in the journal AIDS, researchers conducted a meta-analysis of 18 studies of MSM in which new STI diagnoses were reported. Five of the studies included MSM given PrEP, and 14 were conducted with MSM who were not given PrEP. (One study, the PROUD study, included both a group given PrEP immediately and a group given PrEP on a deferred basis and thus fell into both the PrEP and the non-PrEP categories of studies.)

The researchers found that the rates of new diagnoses of STIs among MSM given PrEP were 25.3 times greater for gonorrhea, 11.2 times greater for chlamydia and 44.6 times greater for syphilis, compared with the rates among MSM not given PrEP. After repeating the analysis but excluding studies conducted before 1999, the researchers found that the results were similar.

Looking to parse apart the contributing factors to the higher rate of STI diagnoses among MSM given PrEP, the meta-analysis’s authors theorized that the regular STI testing that is part of taking PrEP might have led to a higher rate of STI detection. A greater number of sex partners and a higher rate of condomless sex among those given PrEP might also have contributed to their higher STI diagnosis rate.

The study is limited by the fact that, except in the case of PROUD, the researchers compared different populations of MSM from study to study. They also compared groups that tested for STIs at different frequencies and used different variations of STI tests. Additionally, the PrEP studies specifically sought out participants engaging in high-risk sexual behaviors, while the other studies might have had different criteria with regard to sexual risk taking. However, participants in many of the non-PrEP studies were indeed recruited based on some level of reported sexual risk taking.

Antibiotic-resistant Gonorrhea on the rise: Are you at risk of drug-resistant STD?

Posted on by

From techtimes.com…

The World Health Organization (WHO) has warned that gonorrhea, a common sexually transmitted disease, has become harder and sometimes even impossible to treat. Neisseria gonorrhoeae, the bacteria that causes the STD, is so smart it evolves to develop resistance against the antibiotics used to treat infection. [Read the WHO report here]

WHO said that decreasing use of condom, poor infection detection rates, urbanization and travel, as well as inadequate or failed treatments all contribute to the rising cases of antibiotic-resistant gonorrhea. “WHO reports widespread resistance to older and cheaper antibiotics. Some countries — particularly high-income ones, where surveillance is best — are finding cases of the infection that are untreatable by all known antibiotics,” WHO said in a statement. WHO experts said that oral sex is driving the spread of super-gonorrhea. In the United States, about two-thirds of those between 15 and 24 years old have had oral sex.

Teodora Wi, from the WHO, said that when antibiotics are used to treat infections of the throat such as normal sore throat, these get mixed with the Neisseria species in the throat, which can lead to resistance.

What makes matters more worrying is that many people with gonorrhea in the throat are not aware they are infected and are more likely to transmit the infection via oral sex. “In the US, resistance [to an antibiotic] came from men having sex with men because of pharyngeal infection,” Wi said.

Undetectable viral load and HIV prevention: what do gay and bi men need to know?

Posted on by

What does undetectable mean? What about undetectable viral load and HIV transmission? And if I’m living with HIV, can I use “undetectable viral load” as an HIV prevention strategy?

From thebody.com…

Risk of HIV transmission is virtually eliminated when people living with HIV are consistently taking effective HIV medication, (known as antiretroviral therapy or ARVs). It’s well-verified by research, and backed up by many years of real world observation: There have been no cases of transmission in couples where the HIV-positive partner was on meds and had “undetectable” viral load test results for at least six months.

But what does this mean for gay and bi men making decisions about sex, whether in ongoing partnerships, casual dating or anonymous encounters?

Gay men syphilis rates over 100x greater than straight men

Posted on by

From medpagetoday.com…

The first state-specific analysis of syphilis among men who have sex with men (MSM) shows they have dramatically higher incidence than men whose only sexual partners are female, the CDC is reporting.

Data from 2015, analyzed with a new methodology, show that the incidence of primary and secondary syphilis among MSM was 309.0 cases per 100,000 people, compared with 2.9 per 100,000 among men who reported sex with women only, according to Alex de Voux, PhD, of the CDC’s epidemic intelligence service, and colleagues at the CDC and Emory University in Atlanta.

The disparity was even more marked when the rate among MSM was compared with the 1.8 cases per 100,000 population seen among women, the researchers reported in the April 7 issue of Morbidity and Mortality Weekly Report.

County-by-county data from the U.S. Census Bureau’s American Community Survey included the number of households with a male head-of-household and a male partner, De Voux and colleagues reported, and that information could be used to estimate the MSM population per county.

For the syphilis analysis, the researchers used data from the 44 states that had information on the sex of partners in at least 70% of reported cases. Those states accounted for 83.4% of all 23,872 reported cases in 2015, De Voux and colleagues reported.

State-specific incidence rates among MSM ranged from 73.1 per 100,000 population in Alaska to 748.3 in North Carolina, the investigators found. Syphilis incidence among MSM was highest in the South and West and four of the five states with the highest rates among MSM — Louisiana, Mississippi, North Carolina, South Carolina, and New Mexico — were in the South.

The overall syphilis among MSM was 167.5 times the rate among women, with state-specific rate ratios ranging from 63.7 in Louisiana to 2,140.3 in Hawaii, De Voux and colleagues reported.

Interestingly, the highest overall syphilis rate in the U.S., seen in 1946, was 70.9 cases per 100,000 population — a rate exceeded by the lowest state-specific rate among MSM in 2015: the 73.1 cases per 100,000 observed in Alaska.

The researchers cautioned that the data are based on 44 states and might not reflect the nation as a whole. Similarly, the estimates rely on the American Community Survey data; under-reporting of same-sex households would skew the outcome.

As well, they noted, the analysis did not include cases in which the sex of partners was unknown and if MSM are less likely than other men to report the sex of their partners, the findings might under-estimate the rate of disease among MSM.

Finally, De Voux and colleagues cautioned, not all cases of syphilis are diagnosed and reported.

Gay men headed for an STD epidemic?

Posted on by

From Slate.com…

Earlier this month, Poz magazine’s Benjamin Ryan drew attention to a concerning new study out of Northern California’s health system: Using data gathered from July 2012 through June 2015, researchers found that, among a cohort consisting mostly of same-sex–attracted men on the HIV-prevention regimen PrEP, “quarterly rates of rectal gonorrhea and urethral chlamydia increased steadily and about doubled after one year.” In other words, guys on the fantastically effective pill-a-day Truvada program were avoiding HIV infection—there were no new transmissions for regimen-adherent patients over the study period, in fact—but they seemed to be getting other sexually transmitted diseases relatively often.

Health Alert – Rates of STD infection still at record high

Posted on by

The Centers for Disease Control and Prevention (CDC) has recently been reporting a record increase in cases of syphilis, chlamydia and gonorrhea—after these diseases had been on the decline for several previous years. HIV infections continue to increase as well, especially among men who have sex with men (MSM).  Even worse, catching both HIV and one or more STDs can lead to particularly rapid and damaging health outcomes.

As a result, health experts across the country (including here at the Pitt Men’s Study) recommend that all sexually active men get a full screening for STD, especially HIV, Gonorrhea, Chlamydia, and Syphilis.

CDC sending out an SOS over soaring rates of STDs

Posted on by

From the New York Daily News…

Every year, the Centers for Disease Control and Prevention (CDC) releases an annual report of a national overview of sexually transmitted diseases (STDs).

The report for 2015 was not encouraging at all. In fact, it was quite discouraging as such STDs as chlamydia and gonorrhea were at an all-time high, including higher rates of syphilis.

Sexually transmitted diseases are typically not discussed in polite conversation. But the less they are talked about, the more of a hidden epidemic they are becoming.

We need to realize that anyone who has sex — oral, anal or vaginal intercourse and genital touching — can get an STD. It doesn’t matter whether you are straight, married, single or gay, everyone is at risk.

Gonorrhea treatment showing signs of failing

Posted on by

From Project Q Atlanta…

Federal health officials warned of new signs that gonorrhea is growing resistant to current treatments, a development more troubling for gay men who face a higher risk of the sexually transmitted disease than other populations.

Findings of a new study from Hawaii prompted the Centers for Disease Control & Prevention to raise a warning flag on Wednesday during its 2016 STD Prevention Conference in downtown Atlanta. The findings showed that the current treatment for gonorrhea – a shot of ceftriaxone and an oral dose of azithromycin – was losing its effectiveness in a cluster of infections in Hawaii.

That’s more troubling than data released in July that showed emerging drug resistance and limited treatment options for gay men at a time when infections among them are on the rise, federal officials said during a press conference Wednesday.

“It seems that in the battle between humans and pathogens, gonorrhea is a formidable opponent,” said Jonathan Mermin (photo), director of CDC’s National Center for HIV/AIDS, Viral Hepatitis, STD & Tuberculosis Prevention.

“We are seeing troubling signs that treatments are failing us. We may be running out of options for treating gonorrhea,” he added.

Gonorrhea is one of the most common sexually transmitted diseases in the country and it impacts gay men more severely than other populations. The CDC has said about 56 percent of gonorrhea cases in the U.S. are among men and of those, 48 percent are estimated to be gay men. Put another way, men who have sex men face a gonorrhea incidence 17 times greater that seen in heterosexual men and nearly 14 times that seen in women, based on the 2014 STD Surveillance Report.

Pennsylvania still experiencing alarming increase in new syphilis infections

Posted on by

As of May 2016, Pennsylvania is still experiencing an alarming increase in syphilis cases, primarily among men who have sex with men (MSM). Over the last 5 years, Pennsylvania has experienced a 90% increase in syphilis infections. Most were men under the age of 30.

Syphilis is a sexually transmitted infection. If it goes untreated, it can lead to serious health problems including paralysis, blindness, and dementia. In the late stages, the disease can damage internal organs and can result in death.  In its early stages, syphilis is 100% curable with simple antibiotics.

Syphilis can be transmitted through oral sex and although condoms can help prevent infection, they’re not an absolute guarantee against it.  

You can get syphilis and not have any symptoms, so the only way to know you’re infected is to get a simple blood test. As a result of the increase in syphilis cases, the Pennsylvania Department of Health recommends that all sexually active MSM get a routine syphilis test every 6 months. Several locations around the state have free syphilis testing, click on this link to find testing near you: hivtest.cdc.gov.

Social apps responsible for increase in STDs?

Posted on by

From the Pittsburgh Post-Gazette…

About two years ago, Harold Wiesenfeld, medical director of Allegheny County’s sexually transmitted disease and HIV program, started hearing something from some of his patients that troubled him.

“They were volunteering that many of their partners were unknown because they met them through dating apps and it was anonymous,” he said. Apps like Tinder, OkCupid and Grindr that allow people to scroll through dozens or even hundreds of photos of possible potential dates in a given area within a matter of minutes.

Social apps cause rise in STDsMost troubling, though, was that many of those patients in his private obstetrics and gynecology practice at Magee-Womens Hospital of UPMC believed they had contracted their STD from those anonymous partners they met on a dating app.

This occurred as Allegheny County was seeing a sharp and steady rise in cases of Gonorrhea (up 28 percent) and Chlamydia (up 35 percent) from 2006 to 2014 that concerned and worried health officials. Of even bigger concern is the rapid increase in just a few years of Syphilis, which is up 150 percent since 2009. Cases in that time jumped from 27 to 68 for the disease that can have long-term health concerns, particularly for women who want to get pregnant, and their fetus if they are pregnant.

It has become a big enough issue in Allegheny County, that in the last year, Dr. Wiesenfeld has made asking about the dating apps a standard question for his patients.

“Across the country we are in what we consider an STD epidemic, especially with Syphilis and its health implications,” Dr. Wiesenfeld said.

While some of the increase might be attributed to better screening and testing for the diseases, “many of us STD researchers are concerned with the popularity of these apps in facilitating more casual sexual encounters,” he said.

“Half of black men who have sex with men (MSM) will be diagnosed with HIV during their lifetime”

Posted on by

From the Centers for Disease Control and Prevention (CDC)…

If current HIV diagnoses rates persist, about 1 in 2 black men who have sex with men (MSM) and 1 in 4 Latino MSM in the United States will be diagnosed with HIV during their lifetime, according to a new analysis by researchers at the Centers for Disease Control and Prevention (CDC).

The study, presented today at the Conference on Retroviruses and Opportunistic Infections in Boston, provides the first-ever comprehensive national estimates of the lifetime risk of an HIV diagnosis for several key populations at risk and in every state.

“As alarming as these lifetime risk estimates are, they are not a foregone conclusion. They are a call to action,” said Jonathan Mermin, M.D., director of CDC’s National Center for HIV/AIDS, Viral Hepatitis, STD, and Tuberculosis Prevention. “The prevention and care strategies we have at our disposal today provide a promising outlook for future reductions of HIV infections and disparities in the U.S., but hundreds of thousands of people will be diagnosed in their lifetime if we don’t scale up efforts now.”

Vitamin D sufficiency may speed up immune recovery during HAART

Posted on by

From medicalnewstoday.com…

vitimin D aids HARRTThere are an estimated 33 million people infected with HIV worldwide – 1.2 million of them in the US. The advent in 1996 of highly active antiretroviral therapy (HAART) – a combination of different classes of medications taken daily – means that for many patients who have access to the medication, what was once a fatal diagnosis can now be managed as a chronic disease.

For their study, Prof. Ezeamama and colleagues examined 18 months of data for 398 HIV-positive adults on HAART.

The data included a measure of participants’ vitamin D levels at the start of the trial (baseline) and their CD4 cell counts at months 0, 3, 6, 12 and 18.

In their analysis, the researchers looked at how the changes in CD4 cell counts related to the baseline levels of vitamin D over the study period.

They found that participants with sufficient levels of vitamin D at baseline recovered more of their immune function than participants with vitamin D deficiency.

Gonorrhea rising among gay and bi men

Posted on by

From aidsmeds.com…

Diagnoses of gonorrhea among men who have sex with men are apparently rising in the United States. Centers for Disease Control and Prevention (CDC) researchers, in order to determine demographic information, interviewed a random sample of individuals diagnosed with the sexually transmitted infection (STI) in 12 areas across the country between 2010 and 2013. The researchers then used census and Gallup opinion polling data to estimate the respective sizes of the U.S. MSM, heterosexual male, and female populations by age group at the state, county and city levels.

In 2010, there were an estimated 1,169.7 diagnoses of gonorrhea per 100,000 MSM. In other words, about 1.17 percent of MSM contracted the STI that year. This rate rose 26 percent in three years, hitting 1,474.4 diagnoses per 100,000 MSM, or 1.47 percent, in 2013. Looking at MSM according to age bracket, those between 25 and 29 years of age  had the highest diagnosis rate: 3,400 per 100,000, or 3.4 percent.

During the study period, gonorrhea diagnosis rate among MSM was between 10.7 and 13.9 times higher than that of women or heterosexual men. While the researchers speculate that the rising gonorrhea rates may be indicative of a national trend, they caution that the data in this study is not nationally representative.
