Trichomoniasis is a sexually transmitted infection caused by the protozoan parasite Trichomonas vaginalis, which can affect both men and women. The clinical manifestations of this infection can vary, and while some individuals may remain asymptomatic, others may experience a range of symptoms.
Key Insights from Research Papers:
- Trichomoniasis in men is often associated with urethral discharge, which may be mild to moderately severe, and the resolution of urethritis is linked to the elimination of Trichomonas vaginalis.
- Infected men frequently present with symptoms of urethral discharge, and while signs of urethral discharge are not always evident, the presence of T. vaginalis is associated with symptoms of urethral discharge.
- Women with trichomoniasis may experience symptoms such as yellow discharge, abnormal vaginal odor, and vulvar itching, and signs including colpitis macularis ("strawberry cervix"), purulent vaginal discharge, and vaginal and vulvar erythema.
- Clinical features of trichomoniasis in women may also include pelvic organ tenderness, such as adnexal, cervical, and vaginal erythema, friability, and mucopurulent discharge, particularly in the context of pelvic inflammatory disease (PID).
- The classic description of trichomoniasis, which includes symptoms like abnormal vaginal discharge and greater than 10 white blood cells per high power field on wet preparation, cannot be uniformly relied upon for diagnosis, but these features are associated with an increased risk of infection.
Conclusion:
Trichomoniasis presents with a variety of symptoms that can include urethral discharge in men and vaginal symptoms such as discharge, odor, and itching in women. Physical signs may also be present, such as a "strawberry cervix" and erythema of the vulva and vagina. While some individuals may not exhibit noticeable symptoms, those with symptoms often have an increased risk of infection. Diagnosis can be challenging due to the variability of symptoms, and careful clinical examination along with appropriate testing is necessary for accurate detection and treatment.
