10

What is an opportunistic infection?

One that exploits opportunities of weakened host e.g. compromised immune system or altered microbiota

11

- Pregnancy
- Diabetes
- Use of broad spectrum antibiotics
- Use of corticosteroids

14

Why can broad spectrum abx lead to vulvovaginal candidiasis?

They can alter the normal vaginal flora allowing candida albicans to overgrow

15

How can corticosteroids use lead to vulvovaginal candidiasis?

It has an immunosuppressive action

17

What can occur to patients who are immunosuppressed/compromised who have vulvovaginal candidiasis?

Can lead to life-threatening infection

What investigations are needed to diagnose vulvovaginal candidiasis?

None if the history indicates an acute uncomplicated case

24

What investigation can be undertaken if examining a woman for vulvovaginal candidiasis?

pH

25

What is defined as an acute uncomplicated case of vulvovaginal candidiasis?

- Sporadic
- Mild to moderate symptoms
- No risk factors

26

What tests should be carried out in complicated cases of vulvovaginal candidiasis?

- Vaginal smear
- Microscopic investigation

27

What features of microscopy are indicative of vulvovaginal candidiasis?

- Spores
- Mycelia

28

29

What should be prescribe for a single episode of vulvovaginal candidiasis?

Intravaginal antifungal e.g. clotrimazole or oral antifungal e.g. fluconazole

30

Where can antifungals for vulvovaginal candidiasis be obtained?

OTC

31

What is important to keep in mind when using topical treatments for vulvovaginal candidiasis?

They can weaken latex condoms

32

After what period of no response to treatment should women return?

7-14 days

33

What should be considered if vulvovaginal candidiasis does not respond to treatment?

- Alternative diagnosis
- Predisposing risk factors
- Patient's concordance with medication

34

What should be performed if considering alternative diagnosis for vulvovaginal candidiasis?

- Vaginal pH
- Vaginal swab for microscopy and culture

35

When should vulvovaginal candidiasis be referred to a specialist?

- If non-albicans Candida species
- No symptom resolution

36

How should severe cases of vulvovaginal candidiasis be treated?

3 doses of oral fluconazole 3 days apart

37

How are oestrogen levels thought to increase risk of vulvovaginal candidiasis?

- By stimulating increased glycogen production providing a more favourable environment for candida growth
- Directly promoting growth and adherence of candida

38

What is the result of oestrogen promoting candida growth?

Increased risk of vulvovaginal candidiasis in pregnancy

39

How should vulvovaginal candidiasis be managed in pregnancy?

- Treat with intravaginal antifungal
- Don't give oral antifungals
- Treat vulval symptoms with topical antifungals
- Be careful when inserting intravaginal applicator
