This is a common disease, now called vulvovaginal pseudomycosis (VVC for short), which used to be called Candida vaginitis, mycosis fungoides. It is said to be common because about 75% of women have at least one episode in their lifetime, while 40-50% have more than 2 episodes, and a small percentage of 5-8% may have more than 4 episodes a year. Under normal circumstances, there are lactobacilli in human vagina to maintain the weak acidic environment in the vagina. Pseudomonas is a common parasitic bacteria in women’s vagina; when the body resistance decreases, especially the local resistance, or when the virulence of pseudomonas increases, the body resistance is weaker than the invasion, which eventually leads to the proliferation of pseudomonas and the formation of VVC through the destruction of the body’s vaginal epithelial cells. VVC. pseudomonal yeast is not a bacterium, it is a type of fungus. VVC alone is not difficult to treat, and can be treated with vaginal antifungal suppositories (the specific duration of use depends on the drug used), without the need for oral antifungal drugs. The treatment of VVC alone can choose one of the following treatment options: 1, clotrimazole suppositories or clotrimazole tablets 500mg, single dose or clotrimazole suppositories 100mg, once a night for 7 days; 2, miconazole soft capsules 1200mg, single dose; or miconazole suppositories or miconazole soft capsules 400mg, once a night for 3 days; or miconazole suppositories 200mg, once a night for 7 days 3. 100,000 units of mycoplasma effervescent tablets, once a night for 14 days; or 500,000 units of mycoplasma tablets, once a night for 14 days; 4. 150 mg of fluconazole, once a day; some of the above drugs are over-the-counter and can be bought in pharmacies, but in the first occurrence, it is recommended to go to the hospital to make a diagnosis instead of using drugs indiscriminately by yourself. VVC is a fungal infection and should not be treated with bacterial “anti-inflammatory drugs”. Common antibacterial drugs are not effective against fungi and may aggravate the fungal infection. However, this measure is no longer recommended, and evidence from evidence-based medicine proves that vaginal douching increases the incidence of pelvic inflammatory disease and ectopic pregnancy. Avoid sexual intercourse during treatment. It is only necessary to review the leukorrhea one week after treatment or at the next menstrual period. About 84% of women experience recurrence after their first VVC and the reasons for recurrence are varied. Pregnancy, oral contraceptive use, antimicrobial use, diabetes, vaginal douching, immunosuppressants, HIV infection, are all factors that contribute to VVC recurrence, and some will have a somatic susceptibility that is genetically related. Knowing these predisposing factors can be an interesting way to avoid them, such as avoiding the use of “anti-inflammatory drugs” and vaginal douching; the treatment of recurrent VVC starts with checking for the presence of these predisposing factors. Treatment strategies include intensive treatment and consolidation therapy. Intensive treatment options can be one of the following: 1. Clotrimazole suppositories or tablets 500 mg, applied on days 1, 4, and 7; or Clotrimazole suppositories 100 mg, once a night for 7 to 14 days; 2. Miconazole suppositories or softgels 400 mg, once a night for 6 days; or Miconazole suppositories 1200 mg, applied on days 1, 4, and 7; 3. Fluconazole 150 mg, tonsure, applied on day 1, day 4, day 7; after the review to know that no fungus exists, the next step needs to consolidate the treatment. There is no more mature program at home and abroad. For those who have regular attacks once a month, preventive medication can be given once before each attack for 6 months. In the case of irregular episodes, medication can be administered once a week for 6 months. Usually no treatment is needed for asymptomatic sexual partners. About 15% of men have glansitis after contact with female patients. Symptomatic men should be tested and treated for pseudofilamentous yeast to prevent repeat infection in women. VVC attacks during pregnancy are also a common problem. Medications can be used during pregnancy, but oral medications cannot be used during pregnancy. Of the vaginal suppositories, clotrimazole is a class B drug and is safe to use, miconazole and fluconazole are class C drugs and are not considered first.
