Prevalence, Associated Factors, and Antifungigram of Vulvovaginal Candidiasis among Pregnant Women Receiving Antenatal Care At Lira Regional Referral Hospital
This study at Lira Regional Referral Hospital reveals a high 40.6% prevalence of vulvovaginal candidiasis among pregnant women, driven by factors such as high parity and antibiotic use, with a significant shift toward non-albicans species and alarming nystatin resistance that underscores the need for Clotrimazole as a preferred treatment.

Imagine the human body as a bustling city, and the vagina as a busy, vibrant neighborhood. In a healthy city, there's a perfect balance of residents: helpful bacteria act like friendly neighbors who keep the streets clean and organized, while occasional "uninvited guests" like yeast (a type of fungus called Candida) are kept in check by the neighborhood watch. But sometimes, the balance tips. The helpful neighbors get pushed out, and the yeast throws a wild, uncontrolled party, causing an itchy, uncomfortable infection known as Vulvovaginal Candidiasis (VVC). This is especially tricky during pregnancy, when the body's hormonal changes can act like a massive invitation for the yeast to move in and set up camp. While this infection is common and usually treatable, it can cause serious trouble for both mom and baby if not handled correctly. The big mystery scientists are trying to solve is: Who is throwing these parties, why are they happening so often in certain places, and what weapons (medicines) actually work to stop them?
This story takes place at Lira Regional Referral Hospital in Uganda, where researchers decided to investigate the yeast party among pregnant women. They wanted to know three main things: How many women were affected? What factors were inviting the yeast in? And, most importantly, which medicines were still strong enough to kick the yeast out?
The team looked at 138 pregnant women visiting the hospital for check-ups. They found that the yeast party was happening more often than expected: 40.6% of the women had an active infection. That's nearly four out of every ten women! When they investigated the "guest list," they discovered a surprising twist. For a long time, doctors thought one specific type of yeast, Candida albicans, was the main culprit. But in this study, the tables had turned. The "non-albicans" species (the other, less common types of yeast) were actually the ones throwing the biggest bash, making up 65.07% of the infections, while the traditional C. albicans only accounted for 34.93%.
The researchers also played detective to find out what was making the yeast so welcome. They found that certain life circumstances acted like open doors for the infection. Women who had given birth to four or more children (high parity) were 4.33 times more likely to have the infection. Taking antibiotics for more than two weeks was a huge factor, nearly 5 times more likely to lead to an infection, likely because the antibiotics wiped out the good bacteria that usually keep the yeast in check. Women who had already had this infection before were 3.22 times more likely to have it again. Interestingly, the study found that being in the second trimester of pregnancy (weeks 13–28) was actually a "safe zone," making women significantly less likely to get infected compared to the first trimester.
Finally, the team tested the "weapons" available to fight the yeast. They wanted to see which medicines were still effective. The results were a mix of good news and a serious warning. Clotrimazole was a superhero, working against 90% to 98% of the yeast, whether it was the common kind or the new, dominant non-albicans types. However, Nystatin, a medicine often used as a first-line treatment, was failing miserably. It was ineffective against 70.6% of the common yeast and a shocking 80% of the non-albicans yeast. It was as if the yeast had learned to wear armor that Nystatin couldn't pierce.
The study concludes that while the infection rate is high and the types of yeast are shifting toward the more stubborn non-albicans variety, there is a clear path forward. Clotrimazole remains a highly effective shield, but relying on Nystatin is like trying to fight a fire with water that has turned to steam—it just doesn't work anymore. The researchers suggest that doctors need to update their strategies, focusing on the right medicines and keeping a close eye on women who have had many pregnancies or taken antibiotics recently, to ensure both mothers and babies stay healthy.
