A 28-year-old unmarried woman from Delhi presents with lower abdominal pain and vaginal discharge for 5 days. She reports fever (38.5°C), dyspareunia, and irregular menses. On examination, she has cervical motion tenderness and adnexal tenderness bilaterally. Cervical swab shows gram-negative diplococci. Pelvic ultrasound reveals free fluid in the pouch of Douglas. Which of the following is the most appropriate next step in management?

Explanation

## Diagnosis: Pelvic Inflammatory Disease (PID) with Gonococcal Infection ### Clinical Features Supporting PID - **Key Point:** The triad of lower abdominal pain, fever, and cervical motion tenderness is diagnostic of PID [cite:Park 26e Ch 21] - Gram-negative diplococci on cervical smear → *Neisseria gonorrhoeae* - Free fluid in pouch of Douglas indicates peritoneal involvement - Dyspareunia and adnexal tenderness confirm upper genital tract inflammation ### Treatment Algorithm for Gonococcal PID ```mermaid flowchart TD A[PID confirmed with gonorrhea]:::outcome --> B{Severity?}:::decision B -->|Mild-moderate outpatient| C[Ceftriaxone 250 mg IM single dose]:::action C --> D[+ Doxycycline 100 mg BD × 14 days]:::action B -->|Severe/hospitalized| E[Ceftriaxone 1-2 g IV/IM Q12H]:::action E --> F[+ Doxycycline 100 mg IV/PO BD × 14 days]:::action D --> G[Add metronidazole if anaerobes suspected]:::action F --> G G --> H[Counsel on partner notification & STI screening]:::action ``` ### Rationale for Correct Answer **High-Yield:** CDC and WHO guidelines recommend **ceftriaxone + doxycycline** as first-line for gonococcal PID [cite:Harrison 21e Ch 137] - **Ceftriaxone 250 mg IM** covers *N. gonorrhoeae* (including resistant strains) - **Doxycycline 100 mg BD × 14 days** covers *Chlamydia trachomatis* (co-infection in 30–40% of cases) - This patient is stable for outpatient management (no signs of sepsis, no peritonitis) **Clinical Pearl:** Even if chlamydia is not detected, empiric doxycycline is given because: - Chlamydia may be missed on initial testing - Co-infection is common and untreated chlamydia leads to chronic sequelae (infertility, ectopic pregnancy) ### Additional Management Points - Add **metronidazole 400 mg TDS × 14 days** if anaerobic infection is suspected (e.g., IUD use, recent abortion) - Partner notification and treatment are mandatory - Repeat pelvic ultrasound in 4–6 weeks if free fluid persists - Counsel on contraception and STI prevention
