Overview
Definition:
Sexually transmitted infections (STIs) are a group of bacterial, viral, and parasitic infections primarily spread through sexual contact, including oral, anal, and vaginal sex
Adolescents are a key population for screening due to higher risk behaviors and potential for long-term sequelae if untreated.
Epidemiology:
Adolescents and young adults (ages 15-24) account for a significant proportion of new STI cases annually, including chlamydia, gonorrhea, and HPV
Factors contributing to this include increased sexual activity, inconsistent condom use, and less frequent healthcare seeking
In India, specific prevalence data for adolescent STIs is evolving but highlights the need for proactive screening.
Clinical Significance:
Untreated STIs in adolescents can lead to serious long-term health consequences, including pelvic inflammatory disease (PID), infertility, ectopic pregnancy, chronic pelvic pain, and increased susceptibility to HIV
Early detection and treatment are crucial for preventing these complications, interrupting transmission, and promoting adolescent sexual health and well-being
Understanding consent laws is paramount for ethical and legal practice.
Adolescent Consent Laws
Minors And Healthcare:
In many jurisdictions, minors are generally presumed incapable of consenting to medical treatment, requiring parental or guardian consent
However, exceptions exist, particularly for sensitive services like reproductive healthcare and STI testing.
Mature Minor Doctrine:
The mature minor doctrine allows adolescents deemed sufficiently mature to understand the nature and consequences of a proposed medical treatment to consent for themselves, even without parental permission
This is often applied to STI screening and treatment.
Confidentiality And Adolescents:
Adolescents often fear that their parents will be informed about their sexual health visits, leading them to avoid seeking care
Confidentiality is a critical factor in encouraging adolescents to access STI screening and treatment
Many public health guidelines and legal frameworks support confidential services for minors regarding STIs.
Legal Framework India:
In India, the specific legal framework for adolescent consent for STI services can be complex
While the Indian Majority Act, 1875, defines adulthood at 18, the Indian Medical Council Act, 1956, and various public health policies emphasize the need for accessible and confidential sexual health services for adolescents
Clinicians must be aware of state-specific regulations and the importance of non-judgmental, youth-friendly services.
Provider Responsibilities:
Healthcare providers must be knowledgeable about consent laws, adolescent confidentiality rights, and offer youth-friendly services
This includes creating a safe environment, using clear and age-appropriate language, and educating adolescents about their rights and options for care.
Screening Recommendations
Routine Screening Indications:
All sexually active adolescents should be screened for common STIs annually, or more frequently if they have multiple partners or engage in high-risk sexual behaviors
This includes screening for chlamydia, gonorrhea, syphilis, and HIV.
Risk Assessment History:
A non-judgmental sexual history is crucial
Key questions include number of partners, type of sexual activity (oral, anal, vaginal), condom use consistency, history of STIs, and partner's STI status
Red flags include symptoms suggestive of STI, history of sexual assault, or substance use impacting sexual decision-making.
Recommended Testing Protocols:
For chlamydia and gonorrhea, nucleic acid amplification tests (NAATs) are preferred, using urine samples for all sexes, and vaginal swabs or cervical swabs for females
HIV screening should be offered to all sexually active adolescents
Syphilis screening (RPR or VDRL) is recommended annually for sexually active adolescents, especially those with risk factors.
Hiv Screening:
HIV screening should be a routine part of adolescent healthcare
A combination approach of counseling, testing, and referral is essential
Confidentiality is paramount.
Other Screening:
Screening for Hepatitis B and C may be considered based on risk factors
HPV vaccination should be offered to all eligible adolescents
Screening for human papillomavirus (HPV) through self-collected vaginal swabs or clinician-collected cervical samples can be part of routine care for sexually active females.
Diagnostic Approach
History Taking:
Detailed sexual history focusing on age of sexual debut, number and gender of partners, type of sexual practices, condom use, previous STI history, and partner's STI status
Inquire about any symptoms
Assess for co-existing conditions and risk factors for other infections.
Physical Examination:
General physical examination looking for signs of infection
Specific examination of external genitalia for lesions, discharge, or inflammation
For females, a pelvic examination may be necessary to assess for cervicitis, vaginitis, or discharge, using appropriate speculum and collection techniques
For males, examination of the penis, scrotum, and inguinal lymph nodes.
Laboratory Investigations:
Nucleic acid amplification tests (NAATs) for *Chlamydia trachomatis* and *Neisseria gonorrhoeae* from urine or genital swabs
Syphilis screening via serological tests (RPR/VDRL followed by confirmatory FTA-ABS if positive)
HIV testing using ELISA or rapid tests, with confirmatory testing for positive results
Microscopy for *Trichomonas vaginalis* and *Bacterial Vaginosis* may be performed on vaginal swabs.
Interpretation Of Results:
Positive NAATs for chlamydia and gonorrhea require treatment and partner notification
Positive syphilis serology requires confirmatory testing and appropriate management
Reactive HIV tests necessitate referral to an HIV specialist for confirmation and management
Positive wet mount for *Trichomonas* or clue cells for BV indicate treatment needs.
Management And Treatment
Chlamydia Trachomatis:
Single dose azithromycin 1g orally, or doxycycline 100mg twice daily for 7 days
Test of cure is generally not recommended unless adherence is questionable or reinfection is suspected.
Neisseria Gonorrhoeae:
Current guidelines recommend ceftriaxone 500mg intramuscularly as a single dose
Due to rising resistance, follow up testing may be considered
Gonorrhea treatment often includes co-treatment for chlamydia if not concurrently diagnosed.
Syphilis:
Primary, secondary, and early latent syphilis: Benzathine penicillin G 2.4 million units intramuscularly as a single dose
Late latent or unknown duration: Benzathine penicillin G 2.4 million units intramuscularly weekly for three weeks.
Hiv Infection:
Referral to an infectious disease specialist for initiation of antiretroviral therapy (ART) and management.
Partner Notification And Treatment:
Crucial for preventing reinfection and further transmission
All sexual partners of an infected adolescent should be notified, tested, and treated empirically if indicated
Public health departments can assist with partner notification.
Complications
Infertility And Ectopic Pregnancy:
Untreated chlamydia and gonorrhea can lead to pelvic inflammatory disease (PID), causing scarring of the fallopian tubes, which can result in infertility and an increased risk of ectopic pregnancy.
Chronic Pelvic Pain:
PID can also lead to chronic pelvic pain in adolescents and young women.
Neonatal Complications:
Maternal STIs can be transmitted to newborns, causing ophthalmia neonatorum (from gonorrhea and chlamydia), pneumonia, or congenital syphilis, leading to severe health problems for the infant.
Psychosocial Impact:
STIs can have significant psychological and social consequences, including anxiety, depression, stigma, and impact on future relationships
Emotional support and counseling are vital.
Prevention Strategies:
Consistent and correct condom use is a primary prevention method
HPV vaccination protects against HPV-related cancers and genital warts
Regular screening for sexually active adolescents, prompt treatment of infections, and open communication about sexual health are key to preventing complications.
Key Points
Exam Focus:
Understand the legal nuances of adolescent consent for STI screening and treatment in India
Master current screening recommendations and management protocols for common STIs in adolescents
Know the complications of untreated STIs and the importance of partner notification.
Clinical Pearls:
Create a safe, non-judgmental space for adolescents to discuss sexual health
Utilize youth-friendly language
Be aware of the mature minor doctrine and confidentiality rights
Advocate for comprehensive sexual education and access to services.
Common Mistakes:
Assuming adolescents are not sexually active
Failing to ask about sexual history comprehensively
Neglecting to counsel on prevention and safe sex practices
