Trichomoniasis - Causes, Symptoms, Diagnosis, and Treatment

Introduction:

Trichomoniasis is transmitted by sexual intercourse and is called a sexually transmitted disease. It is caused by the parasitic protozoan Trichomonas vaginalis. It is one of the most prevalent sexually transmitted diseases because of the widespread infection with T. vaginalis. Unfortunately, T. vaginalis infections have an increased chance of causing gonorrhea, herpes simplex virus (HSV), the human papillomavirus (HPV), and, most crucially, human immunodeficiency virus (HIV). In 2015, around 122 million new cases of trichomoniasis were reported in the United States. Although it is highly curable, a lack of treatment might result in problems. It may also impact pregnancy and raise the chance of contracting and transmitting HIV.

What Is Trichomoniasis?

Trichomoniasis, or trich, is a common and treatable sexually transmitted disease or infection caused by the parasitic protozoan Trichomonas vaginalis. Trich spreads during sexual activity through the vaginal and semen fluids. Females are more likely to be affected than males. It is usually asymptomatic, although some may present with vaginal irritation. When left untreated, it increases the risk of developing an HIV (human immunodeficiency virus) infection.

What Are the Causes of Trichomoniasis?

The primary cause of trichomoniasis is the motile parasite named Trichomonas vaginalis. These parasites spread through sexual transmission. Most commonly, during unprotected sexual intercourse with an infected person leading to contact with vaginal and semen fluids. The other modes of communication are anal sex, oral sex, and genital touching (skin-to-skin contact without ejaculation). It cannot be transferred through casual touches like sharing food or beverages and does not spread when the person kisses, hugs, coughs, sneezes, or while using toilet seats. Trich most frequently affects the lower vaginal tract in females. In addition, it involves the male urethra, the tube through which pee travels.

What Are the Significant Signs and Symptoms Experienced With Trichomoniasis?

Although the infection is readily spread, most infected individuals never experience symptoms. After exposure, the symptoms may manifest within five days to one month, although they may take more time to develop in some cases. The signs range from mild to severe based on discomfort, inflammation, and drainage. Once symptoms appear, they show different effects on men and women.

Trichomonas usually does not result in bumps, although it mostly affects the genital area and causes symptoms like burning when urinating, itching, and vaginal discharge.

Symptoms in Females:

• Greenish or yellowish vaginal fluid with a foul odor.

• Pain during urination or sexual activity.

• Vaginal bleeding after sexual activity.

• Increased desire to urinate.

• Swelling in the groin.

• Vaginal itching, burning sensations, redness, pain, and soreness.

• Lower abdominal pain is uncommon.

Symptoms in Males:

• A white discharge from the penis or genital area.

• Pain during urination or sexual activity.

• Increased desire to urinate.

• Itching or burning sensation after ejaculation or painful urination.

• Inflamed urethra (the tube that promotes urination).

What Are the Complications Associated With Risk Factors of Trichomoniasis?

A higher risk of trichomoniasis is seen in people who do not use protection like condoms while having sexual intercourse with infected people. A person with multiple sexual partners has an increased chance of trichomoniasis. A trichomoniasis-infected person, especially a female, is likelier to transmit illnesses to their partners. If left untreated, the chance of contracting the human immunodeficiency virus (HIV) rises. Later, it may develop into AIDS (acquired immune deficiency syndrome). Pregnant women have a higher chance of preterm birth, early rupture of the membrane, and low birth weight in newborns. In rare cases, it can get transmitted to the newborn during delivery. Research on HIV and Trichomonas vaginalis co-infection in women under community supervision is limited, even though Trichomonas vaginalis infection is highly linked to an increased risk of HIV acquisition and transmission, particularly among women.

How to Diagnose Trichomoniasis?

Testing for trichomoniasis can be done in three different ways.

• Swab Test: In a positive-case scenario, a vaginal or penile swab examination under a microscope may reveal the presence of one or more trichomonads. However, its low sensitivity and insufficient sampling can result in a false negative report.

• Culture: It is the 'gold standard' for identifying infectious diseases. However, Trichomonas Vaginalis culture assays are less expensive for the general public and have a lower sensitivity to the sample than NAAT (nucleic acid amplification tests).

• Nucleic Acid Amplification Tests (NAATs): They are more sensitive and have an appropriate result. Eventually, it will be more expensive than other options.

What Are the Treatment Options for Trichomoniasis?

Trichomoniasis can persist for months or even years without therapy. It won't disappear by itself. Trichomoniasis is highly curable in both males and females. Antibiotics are used to treat trichomoniasis to eradicate the infection-causing organism. Metronidazole and Tinidazole are usually recommended for seven days to kill the parasites. Eventually, the treatment is started with the partner of the infected person. Sexual intercourse is advised only after the first week of treatment to eradicate the infection. Early sexual contact can result in reinfection. During the treatment, consumption of alcohol may cause flushing, nausea, headaches, and stomach cramps. Precautions should be taken by pregnant women, particularly during the first trimester. It is recommended that breastfeeding mothers take Metronidazole 12 to 24 hours before feeding. Topical treatments are less effective than oral antibiotics.

What Are the Side Effects of Antibiotics?

Alcohol consumption can exacerbate complications or side effects in patients. Frequently associated with nausea, vomiting, and an increased heartbeat. Recurrent infection might be possible with early sexual contact after treatment. Approximately one in five people may have a chance of reinfection. The significant side effects of antibiotics are

• Acidity causes heartburn.

• Nausea.

• Altered taste sensation (metallic taste).

How Can Trichomoniasis Be Avoided?

The spread of trichomoniasis is prevented by protected intercourse with condoms (both male and female). Other preventive measures are

• Maintain good vaginal health, as unhealthy genital areas increase the risk of sexually transmitted diseases.

• Maintain a monogamous sexual connection with a single person.

• Do not have too many sexual partners.

Conclusion:

Trichomoniasis is a widespread sexually transmitted infection linked to severe public health issues, such as accelerating HIV transmission. This condition is mostly asymptomatic, and if symptoms are seen, then the symptoms occur differently for both males and females. It can be prevented by maintaining the hygiene of the genital area and using protection while having intercourse. Metronidazole is an effective and affordable treatment option. A single oral dose of Metronidazole is sufficient to kill the parasites, followed by a three-month follow-up to ensure recurrent infection.
