STD Awareness: Sexually Transmitted Diseases and Pregnancy

Posted on August 21, 2012 by Anna

Every month since January 2011, we’ve been sharing installments of our STD Awareness series, and each month, we’ve encouraged you to protect yourself from sexually transmitted diseases (STDs) by using dental dams and condoms. But what if you’re trying to get pregnant? In that case, you’re probably not using condoms! However, it is very important that partners know their STD status — being screened and treated for STDs prior to pregnancy is a good idea for your health, and can protect your future baby.

If you and a partner are trying to get pregnant, you might consider being screened for STDs together.

When present during pregnancy, certain STDs can have negative health effects for you or your future baby (including preterm labor, stillbirth, low birth weight, pneumonia, certain infections, blindness, and liver disease), especially if they are not cured or treated in time. Receiving prenatal care can help prevent these problems, so it is important to be screened and treated for STDs prior to or early in your pregnancy.

During pregnancy, the immune system undergoes changes, which are probably necessary to ensure that the body doesn’t reject the fetus — normally, the immune system recognizes non-self cells as potential pathogens and attacks. These immune system changes might make a pregnant person more susceptible to disease. Latent viral infections, like genital warts or herpes, might come out of dormancy. Additionally, anatomical changes lead to a larger exposed area of the cervix, which is potentially more vulnerable to initial infections. Continue reading →

Over 90 Percent of What Planned Parenthood Does, Part 6: Vaccinations

Posted on August 14, 2012 by Anna

Welcome to the latest installment of “Over 90 Percent of What Planned Parenthood Does,” a series on Planned Parenthood Advocates of Arizona’s blog that highlights Planned Parenthood’s diverse array of services — the ones Jon Kyl doesn’t know about.

You know what they say: An ounce of prevention is worth a pound of cure. Public health experts agree that vaccines are one of the most important advancements in medicine, and are incredibly safe and effective in preventing infectious disease. Many infectious diseases that used to lay waste to their victims are now unknown to many of us in the developed world — polio, whooping cough, measles, and rabies struck fear in the hearts of our forebears, but most young people today barely know what they are (although low rates of vaccination can still lead to outbreaks, such as 2008’s measles outbreak in Tucson). Smallpox, once a terrifying scourge, has been wiped off the planet thanks to vaccination campaigns.

We offer vaccinations against hepatitis A and B, as well as HPV.

Vaccines work by introducing antigens to your immune system. An antigen is a substance, such as a protein on the surface of a virus, that the immune system can recognize as dangerous. It is then able to attack the pathogen and, often, create a “memory” of that pathogen so it can attack it in the event of reinfection. The antigens in vaccines are very safe, and can be derived from many sources, such as inactivated (dead) or attenuated (weakened) pathogens, or fragments of pathogens. Some vaccines, such as those protecting against human papillomavirus and hepatitis B, are made with laboratory-synthesized fragments of the surface proteins of viruses, which are sufficient to produce immune response despite being completely noninfectious.

Planned Parenthood Arizona offers vaccinations against hepatitis A, hepatitis B, and human papillomavirus (HPV). All three of these viruses can be transmitted sexually, and hepatitis B and HPV can cause cancer if the infections become chronic. The hepatitis vaccines have led to all-time lows in rates of hepatitis A and hepatitis B; the HPV vaccine is still new, but emerging evidence suggests a possible decrease in HPV rates as herd immunity grows. Vaccination doesn’t just benefit you and your partner(s) — it benefits society as a whole. Continue reading →

World Hepatitis Day: The History of the Hepatitis B Vaccine

In the early 1970s, Ted Slavin, a hemophiliac, learned his blood was special. Over a lifetime of transfusions, he had slowly amassed a huge collection of antibodies, which are proteins produced by the immune system that attach to invaders, such as viruses and bacteria. When he started receiving transfusions in the 1950s, blood wasn’t screened for diseases, which meant that he’d been repeatedly exposed to some pathogens. His immune system manufactured large amounts of protective antibodies to battle these constant invaders, one of which was hepatitis B virus (HBV) — resulting in blood with extremely high concentrations of hepatitis B antibodies.

After sunshine and smoking, hepatitis B is the most common cause of cancer.

His physician relayed this discovery to Slavin — most doctors wouldn’t have bothered, and in fact might have surreptitiously sold his blood to researchers. Back then, scientists were at work on a hepatitis B vaccine, and hepatitis B antibodies were a hot commodity. Likewise, Slavin needed money — his medical condition precluded regular work, and treatments were costly. He contracted with labs and pharmaceutical companies to sell his antibodies directly, for as much as $10 per milliliter and up to 500 milliliters per order.

When someone has a chronic HBV infection, the virus has “hijacked” some of his or her cells, “tricking” them into manufacturing copies of the virus. A virus consists of an outer protein shell housing genetic information — the blueprint that cells follow when they produce virus copies. When hepatitis B viruses are manufactured in cells, an excess of surface proteins is produced — these waste products litter the bloodstream, and testing for their presence allows people to be diagnosed with HBV infections. These surface proteins are called antigens — and as luck (or evolution) would have it, the antibodies our immune systems produce can attach to viral antigens, helping us to keep pathogens at bay.

STD Awareness: 10 Sexually Transmitted Diseases You Probably Don’t Know About

Posted on July 5, 2012 by Anna

Gonorrhea and chlamydia go back to antiquity. Syphilis took hold in Europe during the late 15th century. Herpes wasn’t on most people’s radars until the early 1980s, and human papillomavirus (HPV) was relegated to relative obscurity in the popular imagination until the HPV vaccines made their debuts less than a decade ago.

Have you heard of CMV, chancroid, or donovanosis?

But there are still a handful of sexually transmitted diseases (STDs) that you might not know about. These include incredibly common infections, as well as those caused by pathogens you might have heard of but probably don’t associate with sexual transmission. They also include infections that are very rare here in Arizona but are much more common in other parts of the world. They all deserve a closer look.

10 Trichomoniasis: What is the most common curable STD? You might guess that it’s chlamydia or gonorrhea, but according to the Centers for Disease Control and Prevention, it’s trichomoniasis (also known as trich, pronounced “trick”). This infection is caused by Trichomonas vaginalis, a single-celled parasite that is actually pretty cute as far as microbes go. What’s not so cute is its propensity to attach to your cells and degrade their surfaces, which on a large scale can produce unpleasant symptoms. Continue reading →

STD Awareness: HPV in Males

Posted on June 13, 2012 by Anna

Human papillomavirus, or HPV, can affect both males and females.

Human papillomavirus, or HPV, affects people of all genders.

Whether it’s worries over Gardasil making girls go wild, or it’s somber discussion about cervical cancer, discourse about human papillomavirus (HPV) centers around its impact on females. But who are most of these females getting HPV from? For the most part, they’re getting it from male partners. And despite the fact that cervical cancer is the most common cancer associated with HPV, it is not the only one. A high-risk strain of HPV can lead to cancers of the penis, anus, mouth, and throat; additionally, there are strains of HPV that cause genital warts, which affect males and females equally. So why don’t males figure very prominently in discussions of HPV and the preventive vaccine, Gardasil?

Mouth, throat, penile, and anal cancers can all be caused by HPV.

Some people think that if they remain abstinent until marriage, they will be able to avoid sexually transmitted diseases (STDs) – but not very many people can say with certainty that their spouses have never had any other sexual partners. Eva Perón, the second wife of Argentine president Juan Perón and a leader in her own right, was made famous here by the musical Evita. According to physician and writer Shobha S. Krishnan, she died in 1952 of cervical cancer – the same fate that befell her husband’s first wife. Many believe that Juan Perón was the source of both women’s ultimately fatal HPV infections.

While one’s own sexual behavior can increase risk for acquiring an STD, it is not the only factor – the sexual history of one’s partner also plays an important role. HPV is especially tricky because there is currently no FDA-approved test for HPV in males – despite the fact that more than half of sexually active males are estimated to have been infected with HPV at some point in their lives. And, because it is so often asymptomatic, a male can carry this virus without knowing it, unwittingly infecting his partners. Continue reading →

Over 90 Percent of What Planned Parenthood Does, Part 4: Helping You Quit Smoking

Posted on May 31, 2012 by Matt

Recent challenges to contraceptive access make the scenario all too easy to imagine: A woman goes to her health care provider to get her annual check-up and to renew her prescription for birth-control pills. She’s been going to the same health center and using the same birth control pills for years, but this time a nurse practitioner refuses to renew her prescription.

Heavy smoking and use of birth control pills increase risk of a first-time heart attack by a factor of 30.

The scenario is easy to imagine when we’ve seen the concept of religious liberty stretched beyond its limits. The concept has been used to trump other liberties, to excuse organizations from compliance with health care mandates that ensure access to the contraceptives that many struggle to afford. But the scenario just described is exactly what happened to a woman in Iowa, whose clinic refused to renew her prescription for birth control pills, not because of bills passed by lawmakers, but because of her age, 42, and the fact she smoked. Those two factors made use of birth control pills risky for her — and a liability for her provider.

Today is World No Tobacco Day, so this installment of our “Over 90 Percent” series takes a look at the toll smoking takes on sexual health, and what Planned Parenthood health centers can do to help people quit. The World Health Organization launched World No Tobacco Day in the late 1980s to encourage tobacco users around the world to quit tobacco for at least 24 hours. It has also served as a day to promote other anti-tobacco initiatives and raise awareness about the effects of tobacco use. Continue reading →

STD Awareness: Viral Hepatitis

Posted on May 22, 2012 by Anna

Hepatitis isn’t commonly thought of as a sexually transmitted disease (STD) — for most people, hepatitis conjures images of contaminated food or unsanitary restaurants. But hepatitis should be on the radar of anyone who is sexually active. There are several different viruses that cause hepatitis, and some can be sexually transmitted, including hepatitis A (HAV), hepatitis B (HBV), and, to a lesser extent, hepatitis C (HCV).

While HBV is most efficiently transmitted through blood, it can also easily hitch rides from person to person via sexual fluids. However, we covered HBV in depth last year in observance of World Hepatitis Day. As May is Hepatitis Awareness Month, we’ll turn the spotlight on HAV and HCV for this month’s installment of our STD Awareness series.

Hepatitis A (HAV)

HAV spreads through fecal-oral contact and is more widespread in parts of the world with poor sanitation. It is relatively rare in the United States, although in 2003 there was a hepatitis A outbreak outside of Pittsburgh — the largest in the United States — that was traced to improperly washed raw scallions. All told, there were 650 confirmed illnesses and four deaths. HAV is very resilient and can survive outside a host for long periods of time – other foodstuffs it can contaminate include filter-feeding shellfish, which can concentrate HAV from contaminated seawater in their tissues. When these shellfish are undercooked, they can pack quite a punch as billions of virus particles are released into the unsuspecting diner’s body.

Vaccination against hepatitis A confers lifelong immunity while sparing you from illness caused by a natural infection.

Unfortunately, no matter how well you clean your fresh produce or how long you cook shellfish, certain sexual activities can increase your risk of acquiring HAV. As with intestinal parasites, which can be present in minuscule amounts of fecal matter, so too can virus particles be present in microscopic bits of feces. Oral contact with the anus (“rimming” or anilingus) is the riskiest activity in terms of HAV transmission — oral-genital contact can also do the trick, as can manual contact between the anus and the mouth. While hepatitis A outbreaks have been reported among MSM – men who have sex with men – populations, oral-anal contact is associated with increased risk for HAV infection regardless of sexual orientation. To reduce your risk of sexual HAV transmission, use latex condoms or dental dams during oral activities. HAV can also be transmitted via blood, and hepatitis A outbreaks have been reported among IV drug users. Continue reading →
