A 32-year-old woman with poorly controlled type 2 diabetes presents with vulvovaginal itching, erythema, and thick white vaginal discharge. Wet mount microscopy shows budding yeast and pseudohyphae. She has no systemic symptoms and normal vital signs. What is the most appropriate next step in management?

## Clinical Scenario Analysis This is a straightforward case of **acute vulvovaginal candidiasis** (VVC) in a non-pregnant, immunocompetent woman with a predisposing factor (poorly controlled diabetes). ### Diagnostic Confirmation - Wet mount showing budding yeast and pseudohyphae is diagnostic - No systemic symptoms (fever, chills, rigors) — rules out invasive candidiasis - Normal vital signs — no sepsis - Localized presentation — no dissemination ### Management of Uncomplicated VVC **Key Point:** Uncomplicated vulvovaginal candidiasis in non-pregnant women is treated with **topical or oral azoles**. | Treatment | Indication | Dosing | |-----------|-----------|--------| | Oral fluconazole | Uncomplicated VVC, non-pregnant | 150 mg single dose | | Topical clotrimazole/miconazole | Uncomplicated VVC, any patient | 1–3 days of cream/pessary | | Oral itraconazole | Alternative azole | 200 mg BD × 1 day | | IV caspofungin | Invasive candidiasis, ICU patients | Reserved for systemic disease | **High-Yield:** A single 150 mg dose of oral fluconazole is the **gold standard** for uncomplicated VVC in non-pregnant women — high efficacy, convenient, well-tolerated. [cite:Harrison 21e Ch 200] ### Why Not Systemic Therapy? - No fever, no signs of dissemination - No immunosuppression (diabetes alone does not mandate IV therapy for localized VVC) - Blood cultures are unnecessary without systemic symptoms **Clinical Pearl:** Always address the underlying cause — glycemic control optimization is essential to prevent recurrence. ### Management Algorithm ```mermaid flowchart TD A[Vulvovaginal candidiasis suspected]:::outcome --> B{Systemic symptoms<br/>or immunocompromised?}:::decision B -->|No| C[Uncomplicated VVC]:::outcome B -->|Yes| D[Invasive candidiasis]:::urgent C --> E[Oral fluconazole 150 mg<br/>single dose]:::action D --> F[IV caspofungin or<br/>amphotericin B]:::action E --> G[Clinical response<br/>in 3-5 days]:::outcome F --> H[ICU monitoring &<br/>repeat cultures]:::action ```
