Management of Common STIs and Treatments

Sexually transmitted infections (STIs) such as trichomoniasis, syphilis, and chlamydia require prompt diagnosis, appropriate antimicrobial treatment, partner management, and patient education to prevent complications and transmission. Treatment varies by infection, with recommended therapies including metronidazole for trichomoniasis, penicillin G benzathine for syphilis, and doxycycline for chlamydia according to Centers for Disease Control and Prevention (CDC) guidelines.

Trichomoniasis

Trichomoniasis is a sexually transmitted infection caused by the parasite Trichomonas vaginalis. Patients commonly present with vaginal itching, discomfort, increased vaginal discharge, and dysuria (painful urination).

Clinical Presentation and Physical Findings

Common symptoms and examination findings include:

Vaginal itching and irritation
Vaginal discomfort
Increased vaginal discharge
Pain or burning with urination
Strawberry cervix, which may appear as small red spots on the cervix
Thick white vaginal discharge

Laboratory and Diagnostic Evaluation

Diagnosis is commonly confirmed through:

Wet mount microscopy (wet prep), which may identify motile trichomonads
Additional nucleic acid amplification testing (NAAT) may be used when available for improved sensitivity

Management and Treatment

The recommended treatment for trichomoniasis is:

Metronidazole 500 mg orally twice daily for 7 days

Patients should complete the entire medication course, even if symptoms improve before treatment is finished.

Patient Counseling and Education

Important counseling points include:

Avoid sexual activity until treatment is completed and symptoms have resolved.
Sexual partners should also receive treatment to prevent reinfection.
Take all medications exactly as prescribed.
Use condoms after completing treatment to reduce the risk of future STI transmission.
A test of cure is recommended approximately 1 month after treatment completion.

Referrals

No referral is typically required unless additional complications or concerns are identified.

Syphilis

Syphilis is a bacterial STI caused by Treponema pallidum. Early symptoms may include oral sores, fever, fatigue, and mucocutaneous lesions. If untreated, syphilis can progress and affect multiple organ systems, including the nervous system.

Clinical Presentation and Physical Findings

Possible findings include:

Mouth sores or painless ulcers
Fever
Fatigue
Mucocutaneous lesions
Elevated temperature, such as a fever of 102.1°F

Laboratory and Diagnostic Evaluation

Syphilis diagnosis involves:

Serum testing, including treponemal and nontreponemal blood tests

Additional evaluation may be necessary if neurological symptoms are present.

Management and Treatment

The recommended treatment for uncomplicated syphilis is:

Bicillin L-A (benzathine penicillin G) 2.4 million units intramuscularly once

Patients with possible neurological involvement require further evaluation and management.

Patient Counseling and Education

Patients should be informed that:

They should seek medical care immediately if they experience mental status changes or neurological symptoms.
Sexual partners must be tested and treated when indicated.
Condoms should be used in future sexual encounters to reduce STI risk.
A Jarisch-Herxheimer reaction may occur within the first 24 hours after treatment, causing symptoms such as:
- Headache
- Muscle aches
- Fever

Follow-up testing is recommended approximately 1 month after treatment to monitor response.

Referrals

The state department of health was notified for appropriate public health follow-up and STI reporting requirements. This notification supports partner notification and disease prevention efforts.

Chlamydia

Chlamydia is a common bacterial STI caused by Chlamydia trachomatis. Many patients are asymptomatic; however, untreated infection may lead to pelvic inflammatory disease and reproductive complications.

Clinical Presentation and Physical Findings

Patients may present with:

Vaginal discharge
Thick white discharge
Few or no symptoms in many cases

Laboratory and Diagnostic Evaluation

Diagnosis is confirmed using:

Nucleic acid amplification testing (NAAT)
Vaginal swab testing, such as a SureSwab test

Management and Treatment

The recommended treatment for uncomplicated chlamydia infection is:

Doxycycline 100 mg orally twice daily for 7 days

Patients should complete the prescribed antibiotic course to ensure adequate treatment.

Patient Counseling and Education

Key counseling recommendations include:

Avoid sexual activity until treatment is completed.
Sexual partners should be tested and treated to prevent reinfection.
Return for evaluation if symptoms develop, including:
- Pelvic pain
- Fever
- Persistent vaginal discharge
- Pain during sexual activity
- Painful urination
A routine test of cure is not generally required for nonpregnant patients unless specific concerns exist.

Referrals

No referral is typically needed unless complications, recurrent infection, or additional reproductive health concerns develop.
