A 28-year-old female sex worker from Delhi attends the ICTC (Integrated Counselling and Testing Centre) for routine screening. Her HIV ELISA is positive, and Western blot confirms HIV-1 infection. CD4 count is 320 cells/μL. She is asymptomatic except for oral candidiasis. She has no history of antiretroviral therapy. What is her current WHO clinical stage, and what is the most appropriate next step in management?

Explanation

## WHO Clinical Staging and ART Initiation This patient requires classification by **WHO clinical stage** and assessment of **CD4 count** to guide ART initiation. ### WHO Clinical Staging (Simplified) | Stage | Clinical Features | CD4 Threshold | ART Indication | |-------|-------------------|---------------|----------------| | **Stage 1** | Asymptomatic or PGL | Any CD4 | CD4 <350 or symptomatic | | **Stage 2** | Mild mucocutaneous disease (oral candidiasis, seborrheic dermatitis, recurrent herpes) | Any CD4 | **Initiate immediately** | | **Stage 3** | Advanced mucocutaneous + systemic (TB, pneumonia, diarrhea >1 month) | Any CD4 | Initiate immediately | | **Stage 4** | AIDS-defining (PCP, toxoplasmosis, CMV, cryptococcal meningitis, MAC) | <50 | Initiate immediately + OI prophylaxis | ### This Patient's Classification **Key Point:** Oral candidiasis = **WHO Stage 2** (mild mucocutaneous disease) - **Clinical stage:** Stage 2 (oral candidiasis) - **CD4 count:** 320 cells/μL - **Serostatus:** Confirmed HIV-1 positive - **Prior ART:** None ### ART Initiation Criteria (Current WHO/India Guidelines) **High-Yield:** According to **2023 WHO consolidated guidelines** and **NACO (National AIDS Control Organization) India guidelines**: 1. **All patients with CD4 <350 cells/μL** → Initiate ART immediately 2. **All patients with WHO Stage 2 or higher** → Initiate ART immediately (regardless of CD4) 3. **Asymptomatic with CD4 >350** → Can defer, but early initiation is now preferred ### Why This Patient Gets ART Now **Clinical Pearl:** This patient meets **TWO criteria** for immediate ART: 1. CD4 = 320 cells/μL (below 350 threshold) 2. WHO Stage 2 (oral candidiasis = symptomatic disease) → **Initiate ART immediately** (e.g., TDF/3TC/EFV or TAF/3TC/DTG) ### Treatment of Oral Candidiasis - **First-line:** Fluconazole 200 mg daily × 7–14 days - **Prophylaxis:** If CD4 <50 cells/μL, consider fluconazole 100 mg daily - **Note:** Candidiasis usually resolves within 2–4 weeks of ART initiation ### Mnemonic for ART Initiation Triggers **STAGE 2 or CD4 <350 = START ART** - **S** = Symptomatic (Stage 2–4) - **T** = TB or other OI - **A** = Any Stage 3–4 disease - **R** = Recent diagnosis (all patients now) - **T** = Treat early (current paradigm) - **E** = Every patient with CD4 <350 [cite:NACO India ART Guidelines 2023; WHO Consolidated Guidelines 2023]
