Treatment of Desquamative Inflammatory Vaginitis
Desquamative inflammatory vaginitis (DIV) is most effectively treated with either topical 2% clindamycin or topical 10% hydrocortisone for initial therapy, with treatment typically required for 4-6 weeks followed by maintenance therapy in many cases. 1
Diagnosis and Clinical Characteristics
DIV is a chronic inflammatory condition characterized by:
- Vaginal inflammation and rash
- Purulent vaginal discharge
- Diffuse exudative vaginitis
- Epithelial cell exfoliation
- Vaginal pain and discomfort
Laboratory findings typically include:
- Elevated vaginal pH
- Increased parabasal cells on microscopy
- Absence of normal lactobacilli
- Presence of inflammatory cells
- Often gram-positive cocci on Gram stain 2
DIV occurs almost exclusively in white women, with a mean age of approximately 48-49 years, and affects both pre- and postmenopausal women. 1
Treatment Algorithm
First-Line Treatment Options:
Topical 2% clindamycin cream or suppositories
Topical 10% hydrocortisone
- Apply intravaginally once daily for 4-6 weeks 1
- Particularly useful when inflammatory component is prominent
Treatment Response and Duration:
- Most patients (86%) experience significant symptom relief within approximately 3 weeks 1
- Initial treatment should continue for a median of 8 weeks 1
- A favorable initial response to therapy is associated with better long-term prognosis 1
Maintenance Therapy:
- Approximately 58% of patients remain asymptomatic but dependent on maintenance therapy at 1 year 1
- Maintenance regimens typically involve less frequent application (2-3 times weekly) of the effective initial treatment
For Postmenopausal Women:
- Consider supplementary estrogen therapy to maintain remission 2
- This may help address potential estrogen deficiency that could play a role in pathogenesis
Treatment Outcomes and Prognosis
Based on follow-up data at 1 year 1:
- 26% of patients achieve complete cure
- 58% remain asymptomatic but require maintenance therapy
- 16% achieve only partial control of symptoms
Relapse is common, occurring in approximately 32% of patients within 6 weeks after treatment discontinuation 1
Differential Diagnosis
DIV must be distinguished from other conditions that may present similarly:
- Erosive lichen planus 3
- Candida vulvovaginitis
- Bacterial vaginosis
- Contact irritant vaginitis
- Fixed drug eruptions
- Immunobullous diseases
- Estrogen hypersensitivity vulvovaginitis 4
Special Considerations
- DIV appears to have triggers in approximately 56% of cases, most commonly diarrhea or antibiotic treatment 4
- When ongoing triggers are identified and controlled, some patients can achieve complete cure without maintenance therapy 4
- The condition may represent a disruption in vaginal homeostasis leading to an inflammatory response with increased epithelial cell turnover 4
- No consistent microbiologic pathogen has been identified, though there is often an absence of lactobacilli and increased prevalence of group B streptococci 2
Pitfalls and Caveats
- DIV is often misdiagnosed due to its rarity and similarity to other inflammatory vulvovaginal disorders 5
- Standard treatments for common vaginal infections like bacterial vaginosis or yeast infections will be ineffective
- Long-term maintenance therapy is frequently required, so patients should be counseled about the chronic nature of this condition
- Treatment discontinuation should be attempted gradually with careful monitoring for relapse
- If symptoms persist despite appropriate therapy, reconsider the diagnosis and evaluate for other conditions in the differential diagnosis
