Ways to manage recurring bacterial vaginosis
Saturday, March 6th, 2010Many medical studies have been conducted to examine the cure rates of bacterial vaginosis (BV) treatments with antibiotics. Generally, 80-90% of women showed good initial response to the treatments. However, about 15-30% of these women experienced recurring bacterial vaginosis within 3 months after treatment.
A long-term medical study found that more than half of women who were treated with antibiotics would be hit by at least another episode of BV. Most recurrence cases happened in the first year, and one of the most obvious risk factors was having new sexual partners.
For women who are prone to recurring bacterial vaginosis, making some lifestyle changes, including stopping douching and replacing IUD with another method of contraception, will greatly help to prevent another episode.
By now, it is known that bacterial vaginosis is not an infection that can be acquired through sexual activity, because women still experience recurring bacterial vaginosis despite their male sexual partners were being treated for BV. Current medical evidence is more supportive of the relapsing theory, which explains that the disruption of vaginal flora are actually triggered by some factors, and that causes bacterial vaginosis symptoms.
The exact mechanism of recurring bacterial vaginosis remains a mystery – whether a reduction in lactobacilli happens first, or an increase in the vaginal pH or an overgrowth of BV-causing bacteria takes place first. Fortunately, there are therapeutic options available to treat recurrent bacterial vaginosis.
Bacteria replacement therapy (or known as bacteriotherapy)
This method uses harmless bacteria to replace BV-causing bacteria with lactobacilli, and is considered natural and safe. Lactobacilli bacteria are used, either given orally or applied vaginally. However, scientists found that not all lactobacilli strains can stick on well to the vaginal lining.
The lactobacilli group found in yogurt doesn’t seem to stick very well to the vaginal wall. The L crispatus and L jensenii showed better ability to adhere compared with other lactobacilli strains. A medical study reported that normal flora vagina can be regained following a combination of oral and vaginal lactobacilli replacement therapy for 60 days. There are now studies to examine the effectiveness of vaginal pessaries containing L crispatus in repopulating the vagina with lactobacilli.
Vaginal maintenance treatment
Before the normal vaginal microflora balance is restored and able to naturally maintain the vaginal pH themselves, using external aid to adjust the vaginal pH is important to prevent overgrowth of BV-causing pathogens. One study demonstrated that about 88 out of 100 women who used intravaginal lactate gel had their BV completely cured, versus only 10 out of 100 women cured when no vaginal maintenance therapy was employed.
Preventing overgrowth of BV-causing organisms
Bacterial vaginosis recurrences most often take place within the first 7 days of the menstrual cycle, and frequently followed a Candida infection. Experts advise the use of oral or intravaginal metronidazole for 3 days at the onset of menstruation for 3-6 months, and add anti-fungal treatment if the woman has had candidiasis before.
Using one of the above therapeutic options may help some women to end recurring bacterial vaginosis, but may not cure all cases. A combined approach appears to work better for most women. For example, in a study where women took a single dose of oral metronidazole followed by vaginal lactate tablets, there was an improved rate of normal vaginal flora in 94% of women, compared to only 71% of women if no vaginal maintenance treatment was used.
It seems that the ideal way of managing recurring bacterial vaginosis would be to tackle all aspects of this vaginal disorder by replenishing the lactobacilli, at the same time maintaining the vaginal pH at 4.5, and if necessary also adding complementary treatment to control bacteria overgrowth. In fact, many natural cures for bacterial vaginosis practiced today are in line with these medical evidence, and many women are turning to natural remedies as a resort to their BV woes.
