Vulvo vaginal candiasis

Refresh your memory on “Vulvo vaginal   candiadiasis”. This is commonly due to invasion by   C  albicans but   occasionally   is caused by other   Candida species   or yeasts .Please do remember that VVC is not usually acquired through sexual   intercourse no data support  the treatment    of sex partners.

 What may be the clinical features ?? Ans:  Symptoms include pruritus virginal soreness dyspareunia external dysuria and abnormal vaginal discharge. This is by   uncomplicated Vulvo vaginal candiadiasis .But a severe case   may present from simple candidal vaginitis to     dysuria and vulval   pruritus,   pain &  swelling in vulval areas . Signs over vulva are include vulvar edema,   fissures , excoriations or thick curdy  vaginal   discharge. It is more common in pregnancy period  and in the premenstrual   period.
Do U have a microscope at your chamber?? Hyphae can be observed by  wet smear /Gm stain at your clinic. How to clinically diagnose candida infn?? Ans: The  diagnosis can be made when  either  a wet preparation  or Gram stain of vaginal discharge  demonstrates Hyphae or pseudohyphae . Culture is possible but limited to metro cities . That will offer the   yeast    species.
I  do have pH paper at my clinic: Will that be helpful??? : Sorry ::  No . Candida vaginitis  is associated with a normal   vaginal   pH   and therefore    pH   testing is not a useful  diagnostic  tool Indentifying candida by culture  in  the absence  of symptoms  or signs is not an indication for treatment  because approximately  10 to 20 % of women   harbor Candida sp and other   yeasts in the vagina.
Treatment of candida infections
Azoles  is the mainstay. Next in order of merit is Nystatin  Short course topical formulations     are effective. The topically    applied  azole  drugs   are more effective than Nystatin.
Choice is yours:: Topical drugs for fungi (VVC) and doage
A) Clotrimazoles 1%  cream 5 gm intra virginally for  7-14  days or B) clotrimazoles 2%  cream 5 gm intravaginally for 3 days C) Miconazole 2%   cream 5 gm  intravaginally for 7 days or D) miconazole 4%  cream 5 gm intra vaginally      for 3 days or E)  Miconazole 100 mg vaginal suppository   one suppository for 7days or  F) miconazole 200 mg vaginal  suppository one suppository for 3 days or G) miconazole  1200  mg vaginal  suppository one suppository for 1 day.
What about in pregnancy period ??   Ans:--Miconozole is pregnancy category C and  clotrimazoles is a category B   oral   medication.
Recurrence!!!!  Think seriously   for  office based testing Any woman whose symptoms persists  after using an over the counter preparation or who has a recurrent of  symptoms  within two   months “??  How to manage such cases ???  Such cases should be evaluated with office based testing. Unnecessary or inappropriate use for OTC   preparations is common and can lead to a delay in the treatment of other disease. VVC is not usually acquired through sexual   intercourse no data support  the treatment    of sex partners.
  Drugs for  VVC(Vulvo vaginal candiasis)   :: Systemic Antifungal:- : A) A single  oral dose of 150 mg of fulconazole has been approved by US Food and Drug  Administration for the treatment of vaginal  candiadiasis. Its  efficacy is equivalent  to topical  therapy and  B) to oral Itraconazole 200 mg     at two doses 12 hours   apart.
B) Slightly greater efficacy may be achieved with fulconazole 100 mg / day for 5 to 7 days or intraconazole 200 mg / day for 3 to 5 days.
Complicated Vulvo vaginal Candidiasis: What to do??
This occurs in cases with recurrent VVC  severe VVC  non albicans candiadiasis  and women with diabetes debilitation or immunosuppression. In women with recurrent vulvo vaginal candiadiasis RVVC usually  defined as four   or more episodes of symptomatic  VVC in 1 year affects a small percentage of women . The pathogenesis   of RVVC is poorly understood and most women with  RVVC have no apparent predisposing or underlying conditions.
 Longer duration of initial therapy   or a 100 ,150 or 200 mg oral dose of fulconazole every third day for a total of three doses  Vaginal  cultures should be obtained from patients with RVVC  to  confirm   the clinical diagnosis and    to identify unusual species  particularly   candida glabrata ,Although  C glabrata and other non albicans candida  species are  observed  in 10 to 20 % of patients    with RVVC , C glabratea does not form   pseudohyphae or   Hyphae and is not easily recognized on microscopy. Conventional antimycotic therapies are not as effective against these  species as they are against C albians
In cases of recurrent vulvo vaginitis  treatment of the  patient’s   well to short duration oral or topical  azole therapy . To maintain clinical and mycologic   control   a longer duration of initial therapy   or a 100 ,150 or 200 mg oral dose of fulconazole every third day for a total of three doses   should be attempted to obtain mycologic remission before   initiation of a maintenance  antigungal regimen .
Maintenance  regimens.
Oral   fulconazole  weekly for 6 months  is the first line of treatment   . If  this regimen is  not  feasible topical  treatments used  intermittently as a maintenance regimen   can  be  considered. Suppressive maintenance   antifungal   therapies  are effective in  reducing  RVVC  However  30 to 50%  of women will have recurrent  disease after maintenance therapy   is discontinued. Routine    treatment of sexual  partners is controversial C  albicans   azole resistance   is rare in vaginal  isolates ans susceptibility testing  is usually  not warranted  for individual treatment  guidance.
Severe Vulvo vaginal   Candidiasis
Severe  vulvo vaginitis   is associated with  lower clinical  response     rates in patients   treated with short courses of topical  or oral  therapy . A) Either  7 to 14 days of topical   azole or  B) 150 mg of fulconazole in two    sequential doses   is recommended. In severe or very  symptomatic Candida  vulvitis  a topical  corticosteroid for the first 3 to 4 days may be  used .
Non albicans VVC
Options though not very   clear  include  a 7-14   days therapy  with oral  or systemic  non flucanazole azole   drug   . If recurrence occurs 600 mg of boric acid  in a gelatin   capsule   administered  vaginally   once a day  for 2 weeks is recommended.
