Trichomoniasis: the sexually transmitted infection more tenacious than expected

According to a recent US study, trichomoniasis, a very common sexually transmitted infection (STI), has been reported to have been poorly treated in recent decades. While doctors prescribe a single dose of antibiotics to patients, they should be treated for at least a week.

That could change the lives of millions of people around the world. According to a new American study published Friday, October 5 in the journal Lancet Infectious Diseases, the treatment proposed for more than thirty years to women suffering from trichomoniasis, a very common Sexually Transmitted Infection related to Trichomonas vaginalis, is ineffective.

While patients receive a single dose of antibiotic, they should actually be treated over a week, say the researchers. AND it would be valid for the 2 sexual partners, of course, if we want to avoid cascade reinfections, the famous "ping-pong" effect.

Ineffective monodose treatment

Professor Patricia Kissinger of Tulane University of Public Health and Tropical Medicine and her colleagues followed more than 600 women with trichomoniasis in New Orleans, Louisiana, Jackson, Mississippi, and Birmingham, Alabama. More than half of the participants took a single dose of metronidazole while the rest were treated for seven days. As a result, at the end of the study, those who had taken the drug several times were half as likely to still have the infection as those who had taken only one dose of antibiotics.

"There are approximately 3.7 million new cases of trichomoniasis diagnosed every year in the US, which means that many women have been treated poorly for a very long time," said Patricia Kissinger, who is hopeful that the Center for Control and Disease Prevention changes the treatment recommendations for the study. "We can not do anything under the pretext that this is what we have always done, and I hope that this study will help change the recommendations so that women can be properly treated in the face of this common STD" -she.

An infection that goes unnoticed in half of the cases

About 143 million women are diagnosed with trichomoniasis each year worldwide and although 50% of them do not suffer from any symptoms, the infection can lead to many complications, especially at the birth of the child. an infected woman (risk of infections of the urinary tract or vagina in infants). Moreover, like all STIs, it weakens the mucosa and considerably increases the risk of contamination by the AIDS virus

When they are visible, the symptoms can result in abnormal and abundant vaginal discharge, especially smelly, burning and itching in the vulva and vagina and pain when the woman is urinating. Finally, if this disease is especially the prerogative of young women, it happens that some men suffer. It will then manifest as redness and pain in the urethral orifice and furrow at the base of the glans, as well as burns when urinating and sometimes a flow at the exit port of the 'urethra. Above all, the germ can go up in the urinary tract of the man and give infections of the prostate and chronic prostatitis, whose link with the cancer was evoked

If you suffer from these symptoms, go to your doctor immediately so that the doctor prescribes laboratory tests. In women, the diagnosis is made by a simple cervicovaginal sampling while in humans, the laboratory technician will perform urethral swabs. The treatment must concern the 2 sexual partners at the same time.
