Prevalence of Candidiasis amongst Undergraduate Students of COOU, Uli, Nigeria

Most urinary tract infections are due to Candida species, C. albicans being most prevalent. Laboratory research study was used to examine the prevalence of candidiasis amongst undergraduate students of Chukwuemeka Odumegwu Ojukwu University, Uli. A total of 100 students were investigated. Clean catch midstream urine samples were used for the analysis. Standard microbiological procedures were utilized. A structured questionnaire was issued to each student to obtain their socio-demographic data. Our study found Candida albicans in 14(14%) of the urine samples. Significant candidiasis was strongly associated with being female as higher percentage of the isolates were from female students. Of the 14(14.0%) positive urine samples, 4(28.6%) were from symptomatic students, whereas 10(71.4%)

Laboratory research study was used to examine the prevalence of candidiasis amongst undergraduate students of Chukwuemeka Odumegwu Ojukwu University, Uli. A total of 100 students were investigated. Clean catch midstream urine samples were used for the analysis. Standard microbiological procedures were utilized. A structured questionnaire was issued to each student to obtain their socio-demographic data. Our study found Candida albicans in 14(14%) of the urine samples. Significant candidiasis was strongly associated with being female as higher percentage of the isolates were from female students. Of the 14(14.0%) positive urine samples, 4(28.6%) were from symptomatic students, whereas 10(71.4%) were asymptomatic. Although candida vulvovaginitis occurs commonly, the reasons for its occurrence and recurrence are often unclear. Several potential risk factors have been described, including the recent use of antibiotics and oral contraceptives, uncontrolled diabetes, increased estrogen levels, impaired immune system, gastrointestinal colonization by the organism, and specific immunological defects. However, the data supporting each of these factors are conflicting, and to date, none are predictive of the infection. This study evaluates the potential risk factors of C. albicans and discusses the implications for clinical practice. We, therefore, recommend that further studies be carried out to determine the definite risk factors of candidiasis.

I. Introduction
ulvovaginal candidiasis (VVC) is a fungal or yeast infection. It is found in the lower genital tract, the vulva, and the vagina of females (Sobel, 2007). When this disease is caused by Candida species, it is known as candidiasis or moniliasis. VVC can be recurrent or relapsing (Nyirjesy and Sobel, 2003). This occurs when a female experiences four or more episodes of VVC per year. Asymptomatic infections occur in about 5% of healthy women (Reset et al., 2000).
VVC remains a common problem worldwide, affecting all strata of the society. The absence of rapid, simple, and inexpensive diagnostic tests continues to result in both over diagnosis and under diagnosis of VVC. About 75% of women will experience at least one episode of VVC during their lifetime. 70 -75% of healthy adult women have had at least one episode of VVC during their reproductive life, and half of the college women will by the age of 25 years have had one case of VVC diagnosed by a physician (Sobel, 2007). VVC is not a sexually transmitted disease, because it also affects children and women who abstain themselves from sexual relationships. However, it can be transmitted sexually (de Leon et al., 2002). Diagnosis of VVC should not be based solely on patient history and a genital examination because of its low specificity of symptoms and signs. In addition, other causes like leukorrhea and pruritus vulvae mimic VVC (Geiger and Foxman, 2006). Therefore, to have a definitive diagnosis of VVC, cultural isolation and identification of Candida spp. are crucial.
Previous findings have provided data on the prevalence of VVC. It is interesting to note that most previous studies focused on immune compromised subjects, especially pregnant women, diabetics, subjects on broad-spectrum antibiotic therapy, women on oral contraception with high estrogen content, and HIV-positive subjects, with few studies on otherwise immunocompetent women. Interrelationships between Lactobacillus acidophilus and other endogenous flora, estrogen, glycogen, vaginal pH, and metabolic byproducts of these micro biomes determine a healthy vagina. L. acidophilus produces hydrogen peroxide V (as a by-product of metabolism), which is toxic to pathogens and keeps the healthy vaginal pH acidic. Alterations of the vaginal micro flora by invading pathogens or biochemical changes in the environment results in vaginitis (Odds, 2008).
Changes in the vaginal environment, Candida population, and their adherence to vaginal epithelial cells enhance the germination of daughter yeast cells (Sobel, 2007). These changes and attendant multiplication of Candida cells may transform asymptomatic colonization into symptomatic infection. VVC, like many vulva diseases, has the potential to cause psychological distress and negatively impact patient's quality of life.

a) Aim of the Study
Our study aims to assess the level of urethritis due to Candida albicans amongst undergraduate students of Chukwuemeka Odumegu Ojukwu University, Uli.

b) Specific Objectives
-Determination of the prevalence of candidiasis amongst undergraduate students -Correlation of the prevalence rates with age, sex, and other risk factors -Evaluating the effects of predisposing factors on both symptomatic and asymptomatic persons.

c) Significance of the Study
Fungal infections of the urinary tract especially, those caused by Candida albicans are becoming increasingly common. Urethritis due to Candida is mostly misdiagnosed or undiagnosed, as most studies concentrate on the bacterial urinary tract infections. Studies on the epidemiology of fungal urinary tract infections are limited in apparently healthy individuals since most studies were carried out in the hospital settings amongst hospitalized patients. There are few studies that provide good databases for guiding public health practitioners on the diagnostic criteria and therapeutic pathways.

d) Limitation of the Study
The study population was undergraduate students. This made the research participants selective. Collection of urine samples from students was burdensome due to the misconceptions and fear of societal ills.
Some students refused to fill the questionnaires.

a) Study Population
One hundred students of Chukwuemeka Odumegwu Ojukwu University, Uli were randomly selected for this research. Only undergraduate students in regular programs were used. Consent was obtained from the participants.

i. Administration of questionnaires
We obtained baseline socio demographic data using well-structured questionnaires and ensured confidentiality amongst the respondents.
ii. Collection of urine samples We gave well-labeled sterile wide-mouthed screw-capped plastic containers with the same unique numbers as written on the questionnaires to the respondents. Each student was instructed on how to collect clean-catch midstream urine sample. 10 ml was obtained from each student.

c) Culture and Identification of Candida albicans
Sterile cornmeal agar plates were inoculated with the urine specimens and incubated at 25 o C for 72 hours. Each plate was read daily, recording the colony size, color and shapes. The isolates were subsequently streaked on sterile Sabouraud dextrose agar plates and incubated at 30 o C for 4days. The pure cultures were Gram-stained and observed microscopically using x100 oil immersion objective (WHO, 2003). i

. Germ tube test
The pure cultures were suspended in test tubes containing 0.5ml human serum. These were incubated at 35 o Cfor 2 hours. A drop of the yeast-serum suspension was placed on a microscope slide and overlaid with a coverslip. This was examined microscopically for the presence of Germ tubes (Winn et al., 2006).

III. Results
We present the socio-demographic characteristics of the study subjects in Table 1. Of the 100 students examined, 80(80.0%) were female and 20(20.0%) were male. Only 8 of the sampled students were married, none was pregnant. Of the sampled students 11(11.0%) knew about urinary tract infection, but only 7(7.0%) had history of urinary tract infection (previously suffered from it). 17% were symptomatic whereas the remaining 83% were asymptomatic. More so, 17(77.2%) students had used antibiotics either by prescription or self-medication, 5(22.7%) said they have not used it.
14 had Candida positive cultures making the prevalence of vulvovaginal candidiasis 14.0%. Candida positive cultures were observed mostly among ages 21-30 years [11(11.0%)]. The majority of students in this age group were in their third to final year and are sexually active. The prevalence of infection between the age groups was statistically not significant (P> 0.05). Therefore, there is no significant difference between the age groups.  Out of the 100 urine samples cultured, 14 showed Candida growth, and the 14 were from female students. The prevalence of infection between the sexes was statistically not significant (P> 0.05). Therefore, there is no significant difference between sexes.

IV. Discussion
Our study found the prevalence of vaginal candidiasis amongst undergraduate students of Chukwuemeka Odumegwu Ojukwu University, Uli, Nigeria to be 14%. Our result is lower than that reported by Aringet al.(2012). In their study the prevalence of candidiasis was 16.5%, 21.31%, and 19 % respectively.
The relatively low prevalence we observed may be attributed to adequate knowledge, good personal hygiene, and normal levels of estrogens and corticoids amongst undergraduate students. Our result is however, in agreement with the studies of Fernández et al. (2004).
We observed candidiasis in students between ages 20 -30 [17 (8. There was no statistically significant relationship between the prevalence of VVC with age (P>0.05) or clinical symptoms of ill health (P>0.05). This may be due to recurrent infections that might have contributed to the resistance of the vagina to candidiasis. Subjects with vulvovaginal discomfort had a higher percentage of Candida-positive cultures (29.1%) than those with no vulvovaginal discomfort (11.9%). This report is in agreement with the findings of Jombo et al. (2010). It is reasonable to believe that young women with genital discomfort consult health care centers more often than women without such symptoms (Jombo et al., 2010).
All subjects with positive Candida culture results had already been on antibacterial therapy prior to their hospital visit -28 (100%). This finding is in conformity with the fact that prolonged antibacterial use usually affects vaginal bacteria micro flora population and biochemical activity (mainly L. acidophilus), which thus increases vaginal pH as a result of reduced CO 2 production. This feature, alongside other factors (such as hormonal factors), encourages Candida overgrowth, consequently leading to vulvovaginitis (Bauters et al., 2002).
Although the widespread use of antibiotics has been suggested as one of the major factors contributing to the rising incidence of VVC, (Foxman et al.,2008)some case-control studies (Geiger et al.,2006) found no evidence of an association between antibiotic agents and symptomatic VCC, whereas others reached the opposite conclusion (Spinillo et al.,2009).

V. Conclusion
There is a need to create awareness of the involvement of Candida spp. in genital discomfort, especially vaginal candidiasis, amongst undergraduate students with or without notable signs and symptoms. It is worthwhile to consider culture test as adjunctive in combination with clinical symptoms in the definitive diagnosis of VVC. More work is required to build on findings generated from this study.

VI. Recommendations
We recommend the following: • The presence of candidiasis among apparently healthy individuals should not be neglected. • Follow-up studies on the appropriate management of asymptomatic candidiasis should be conducted periodically.
• Role of antibiotic usage should be reviewed to delineate the cause of antibiotic resistance in recurrent VVC. • Factors that promote candidiasis among students should be addressed promptly through extensive public health enlightenment programs.
