Association between bacterial vaginosis, Chlamydia trachomatis infection and tubal factor infertility in Bukavu, Democratic Republic of Congo. BMC Infect Dis 2024; 24:480. [PMID: 38730346 PMCID: PMC11083818 DOI: 10.1186/s12879-024-09379-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 05/03/2024] [Indexed: 05/12/2024] Open
Abstract
BACKGROUND Tubal factor infertility (TFI) is common in sub-Saharan Africa and often secondary to pelvic inflammatory disease (PID). Anaerobes associated with bacterial vaginosis (BV) are also found in PIDs widely dominated by Chlamydia trachomatis (C. trachomatis), whose role in TFI is better demonstrated than that of BV. OBJECTIVES To determine the prevalence of BV and C. trachomatis and to investigate the association between BV, C. trachomatis and TFI. METHODS We included 137 patients treated for infertility between January 2020 and November 2021. Cases were defined as women with infertility aged 18-45 years presenting with TFI (n = 52), and controls as infertile women in the same age groups without TFI (n = 85). Data on social habits, life style and infertility parameters were collected, and we performed screening for BV and C. trachomatis. Multiple regression was used to measure associations. RESULTS The prevalence of BV and C. trachomatis was 42.3% (58/137) and 23.4% (32/137), respectively. BV (61.5% vs 30.6%, p<0.001) and C. trachomatis (48.1 vs 8.2%, p<0.001) were more frequent in cases of TFI. BV and C. trachomatis increased the risk of TFI approximately 4-fold [aOR: 3.77 (1.61-8.83), p=0.002] and 14-fold [aOR: 13.77 (4.59-41.27), p<0.001], respectively. CONCLUSION BV and C. trachomatis infection are strongly associated with TFI in Bukavu. Prevention and screening should be implemented to reduce the risk of TFI.

Abstract
Background Genital Chlamydia trachomatis (Ct) is the commonest bacterial sexually transmitted infection globally. Acquisition of Ct infection is affected by biological and behavioural factors. Aim Determine the prevalence of Ct infection and identify risk factors associated with Ct infection in sexually active fertile women in Northern Nigeria. Materials and Methods One hundred and fifty sexually active women presenting to the Obstetrics and Gynaecology department of Ahmadu Bello University Teaching Hospital, Zaria were studied. Socio-demographic characteristics and history of risk factors for acquisition of genital Ct were obtained from the participants using a questionnaire. Their sera were tested for the presence of Ct immunoglobulin G using Enzyme-Linked Immunosorbent Assay. Results The mean ages ± standard deviation of seropositive and seronegative women were 29.1 ± 7.3 years and 28.9 (SD 6.7) years respectively (P = 0.438). The prevalence of Ct infection was 6.7% (10/150). Occupation was associated with Ct seropositivity (P = 0.02). Number of sexual partners, age at coitarche; duration of sexual exposure and previous history suggestive of sexually transmitted infection were not associated with Ct seropositivity (P > 0.05). Conclusion A low prevalence of Ct was found among fertile women. Lack of regular source of personal income was associated with Ct infection but the sexual behavioural factors studied were not.

Abstract
Background Chlamydia trachomatis, Ureaplasma parvum, and Mycoplasma genitalium are common sexually transmitted microorganisms. Our study aimed to determine the prevalence of C. trachomatis, U. parvum, and M. genitalium in infertile and fertile couples and the effect of these microorganisms on semen parameters. Materials and Methods In this case-control study, samples were collected from 50 infertile couples and 50 fertile couples and were subjected to the routine semen analysis and Polymerase chain reaction (PCR). Results C. trachomatis and U. parvum were detected in 5 (10%) and 6 (12%) of semen samples from infertile men. Also, out of 50 endocervical swabs from the infertile women, C. trachomatis and M. genitalium were detected in 7(14%) and 4 (8%) of swab specimens, respectively. In the control groups, all of the semen samples and endocervical swabs were negative. Also, in the group of infertile patients infected with C. trachomatis and U. parvum, sperm motility was lower than uninfected infertile men. Conclusions The results of this study showed that C. trachomatis, U. parvum, and M. genitalium are widespread among the infertile couples in Khuzestan Province (Southwest of Iran). Also, our results showed that these infections can decrease the quality of semen. For the prevention of the consequences of these infections, we suggest a screening program for infertile couples.

Abstract
Infertility is one of the major health problems of patients suffering from bacterial infections. Given the high percentage of infertility, the aim of this study was to investigate the prevalence of Chlamydia trachomatis, Mycoplasma genitalium, Neisseria gonorrhoeae and Ureaplasma urealyticum in fertile and infertile women. In the prospective study, 65 infertile patients and 54 pregnant women referred to Mahdieh Hospital in Tehran were included. After transferring of vaginal swabs to the laboratory, DNA extraction and Polymerase Chain Reaction (PCR) were performed using specific primers. Of the 65 vaginal swab specimens, the prevalence of U. urealyticum, M. genitalium, C. trachomatis and N. gonorrhoeae were as 15 (23.1%), 11 (16.9%), 9 (13.8%) and 4 (6.2%), respectively; However, these rate in fertile group was as 6 (11.1%), 3 (5.5%), 5 (9.2%) and 1 (1.8%), respectively. Bacterial infections were higher in infertile group; therefore, these bacterial agents may be associated with female infertility. Timely control and treatment of infections caused by these organisms, together with other factors, can be important in prevention and treatment of the women's infertility and thereby community health.Impact StatementWhat is already known on this subject? Infertility is one of the most common reproductive health issues in Iran. Female reproductive system is a suitable environment for the growth of many pathogens, which may disrupt any stage of foetal formation, implantation or growth. Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium and Ureaplasma urealyticum are the most important microorganisms that have been considered in the infertility.What do the results of this study add? The prevalence of C. trachomatis, M. genitalium, N. gonorrhoeae, M. genitalium and U. urealyticum were higher in infertile women, but there was no statistically significant compared to pregnant women. These results suggest that timely control and treatment of infections caused by these organisms, along with other factors, can be used to prevent and treat women infertility and community health.What are the implications of these findings for clinical practice and/or further research? Based on the results, designing and implementing national control programs to prevent subsequent complications is thought to be necessary. Comprehensive analyses of the overall prevalence of these bacteria, particularly in developing countries (including Iran), may help to carry out such a strategy.

Abstract
Female urogenital chlamydia is a disease caused by Chlamydia trachomatis infection in the female urogenital tract. It is a common bacterial sexually transmitted disease. The bacteria is transmitted through sexual contact with an infected partner or from mother to newborn during vaginal delivery. The prevalence varies among studies and the number is possibly higher due to the lack of massive screening. Many patients were asymptomatic and still be able to transmit the disease. The undiagnosed and untreated disease could cause pelvic inflammatory disease, which leads to infertility, ectopic pregnancy, and chronic pelvic pain. The prevalence among pregnant women is similar to non-pregnant women, therefore chlamydia screening in pregnant women is highly recommended. The nucleic acid amplification test is the most reliable method for the diagnosis due to high sensitivity. The current treatment is given by prescribing antibiotics. Female urogenital chlamydia is caused by Chlamydia trachomatis. Urogenital chlamydia affects young and sexually active women. Female urogenital chlamydia is diagnosed through indirect methods (serology-based tests) and direct methods (culture). Treatment of chlamydia consists of antibiotics with doxycycline being the first-line choice.

Abstract
Genital Chlamydia trachomatis (CT) has adverse health outcomes for women and children. In pregnant women, the infection causes adverse obstetric outcomes including pelvic inflammation, ectopic pregnancy, and miscarriage. In children, it causes adverse birth outcomes such as skin rash, lesions, limb abnormalities, conjunctivitis, neurological damage, and even death. This article discusses genital CT prevalence, risk factors, and adverse pregnancy and birth outcomes among women and children in sub-Saharan Africa as well as challenges associated with the mitigation of the disease. A comprehensive search of databases including PubMed, ResearchGate, and Google Scholar was conducted using keywords such as genital chlamydia trachomatis, adverse pregnancy outcomes, adverse birth outcomes, and sub-Saharan African. We found that genital CT prevalence rates in some sub-Saharan Africa countries were higher than others and that risk factors such as the lack of condom use, having multiple sexual partners, and low educational levels contribute to the transmission of the infection. We also found that negative cultural practices, illiteracy among women, and the lack of access to screening services during pregnancy are some of the challenges associated with CT mitigation in sub-Saharan Africa. To reduce genital CT transmission in sub-Saharan Africa, efforts must be made by country governments to eliminate negative cultural practices, promote female literacy, and provide access to screening services for pregnant women.

Abstract
BACKGROUND Infertility is the inability to sustain a pregnancy in a woman with regular (2-3 times per week) unprotected sexual intercourse for a period of 1 year. This is a major public health problem that remains under-recognised in Cameroon and most countries in sub-Saharan Africa. This study aimed at identifying the risk factors associated with tubal infertility in a tertiary hospital in Douala, Cameroon. METHODS We conducted a case-control study at the Obstetrics, Gynaecology and Radiology Departments of the Douala Referral Hospital from October 1, 2016, to July 30, 2017. We recruited 77 women with tubal infertility diagnosed using hysterosalpingography and 154 unmatched pregnant women served as controls. Data on socio-demographic, reproductive and sexual health, and radiologic assessments were collected using a pretested questionnaire. The data were analysed using the Statistical Package for the Social Sciences (SPSS) software version 24.0. Logistic regression models were fitted to identify demographic, reproductive health factors, surgical, medical and toxicological factors associated with tubal infertility. The adjusted odds ratios (AOR) and their 95% confidence interval were interpreted. Statistical significance set at p < 0.05. RESULTS Sixty-one per cent of respondents had secondary infertility. Following multivariate logistic regression analysis, respondents who were housewives (AOR 10.7; 95% CI: 1.68-8.41, p = 0.012), self-employed (AOR 17.1; 95% CI: 2.52-115.8, p = 0.004), with a history of Chlamydia trachomatis infection (AOR 17.1; 95% CI: 3.4-85.5, p = 0.001), with Mycoplasma infection (AOR 5.1; 95% CI: 1.19-22.02, p = 0.03), with ovarian cyst (AOR 20.5; 95% CI: 2.5-168.7, p = 0.005), with uterine fibroid (AOR 62.4; 95% CI: 4.8-803.2, p = 0.002), have undergone pelvic surgery (AOR 2.3; 95% CI: 1.0-5.5, p = 0.05), have undergone other surgeries (AOR 49.8; 95% CI: 6.2-400, p = 0.000), diabetic patients (AOR 10.5; 95% CI 1.0-113.4, p = 0.05) and those with chronic pelvic pain (AOR 7.3; 95% CI: 3.2-17.1, p = 0.000) were significantly associated with tubal infertility while the young aged from 15 to 25 (AOR 0.07; 95% CI: 0.01-0.67, 0.021), those in monogamous marriages (AOR 0.05; 95% CI: 0.003-1.02, p = 0.05), as well as those with a history of barrier contraceptive methods (condom) (AOR 0.17; 95% CI: 0.03-1.1, p = 0.06) were less likely to have tubal infertility. CONCLUSION The following factors were independently associated with tubal infertility: being a housewife, self-employed, history of Chlamydia trachomatis, Mycoplasma infection, and uterine fibroid. Furthermore, a history of pelvic surgery and other surgeries, diabetes mellitus, and chronic pelvic pain were also associated with tubal infertility. Young age, persons in monogamous marriages and users of barrier methods of contraception (condom) were less likely to have tubal infertility. Identification of these factors will be a target of intervention to avoid tubal infertility.

Impact of genital Chlamydia trachomatis infection on reproductive outcomes among infertile women undergoing tubal flushing: a retrospective cohort at a fertility centre in Uganda. FERTILITY RESEARCH AND PRACTICE 2019; 5:16.

Abstract
BACKGROUND The impact of current C. trachomatis on clinical pregnancy and live birth rates among women undergoing tubal flushing is largely unknown. This study aimed to investigate whether current female genital C. trachomatis infection affects the chance of achieving a clinical pregnancy and a live birth, among infertile women undergoing tubal flushing, at a fertility centre in Uganda. METHODS A retrospective Cohort study at a peri-urban fertility centre. A total of 253 eligible women with tubal factor infertility, who underwent tubal flushing, were enrolled and categorised according to their exposure to current genital C. trachomatis infection. These women were followed up for a period of 12 months, with the primary outcome measure being clinical pregnancy and live birth. Secondary outcome measures included pregnancy loss and procedural related adverse events. RESULTS Exposure to current genital C. trachomatis infection reduced chance of clinical pregnancy (adjusted relative risk 0.42; 95% confidence interval, 0.18-0.96) and a live birth (adjusted relative risk 0.37; 95% confidence interval, 0.14-0.95) after tubal flushing. Women with current C. trachomatis infection had an increased risk of adverse events (adjusted relative risk, 1.20; 95% confidence interval, 1.08-1.34). However, current C. trachomatis infection did not affect the risk of spontaneous abortion and ectopic pregnancy. CONCLUSION Current genital C. trachomatis infection in women with tubal factor infertility, undergoing tubal flushing, lowers their chance of pregnancy and live birth.

Abstract
This study aimed to estimate the prevalence of chlamydial trachomatis (CT) infection and explore its risk factors among patients attending sexual and reproductive health clinics in Shenzhen, China. We collected demographic and clinical information from attendees (aged 18–49). CT and Neisseria gonorrhoeae (NG) infection was determined by nucleic acid amplification test (NAAT) on self-collected urine specimens. Of 1,938 participants recruited, 10.3% (95% confidence interval [CI]: 9.6%-11.0%) tested positive for CT. Prevalence was similar between men (10.6% [85/804]; 95% CI, 9.5%–11.7%) and women (10.1% [115/1134]; 95% CI: 9.2%–11.0%). Being 18–25 years old (adjusted odds ratio [aOR] = 2.52; 95%CI:1.35–4.71), never tested for CT before (aOR = 2.42; 95%CI: 1.05–5.61) and infected with NG(aOR = 3.87; 95%CI: 2.10–7.10) were independently associated with CT infection. We found that CT infection is prevalent among patients attending sexual and reproductive health clinics in Shenzhen, China. A comprehensive program including CT screening, surveillance and treatment is urgently needed.

Abstract
Human papilloma virus (HPV) infection is an etiological factor for cervical cancer development and Chlamydia trachomatis (Ct) is considered as a cofactor. Understanding the dynamics of HPV and Ct infection could help to explain the incidence of early onset of cervical cancer (CC) observed in Cameroon. Lower vaginal swabs and sera from sexually active women were analyzed for HPV and Ct infection in association with risk factors. Questionnaires were used to document patients' lifestyle and risk factors. A total of 206 women participated in the study average 28.1±8years (16-50 years). HPV prevalence was 23.3% with subtypes 16 and 18 at respectively 2.9% and 1%. Ct infection totalised 40.8%, of which 23.8% were HPV- Ct co-infections. HPV infection was inversely associated with age (p=0.028). We found a positive association between Ct infection and the number of sex partners (p=0.012) and a negative association with parity (p=0.032). There was no significant association between HPV and Ct infections. High rates of HPV and Ct infections could be an indicator of cervical cancer risk in the near future. There is therefore an urgent need for sensitization as well as implementation of appropriate preventive measures.

Genital Chlamydia trachomatis Infection among Women of Reproductive Age Attending the Gynecology Clinic of Hawassa University Referral Hospital, Southern Ethiopia. PLoS One 2016; 11:e0168580. [PMID: 28006003 PMCID: PMC5178988 DOI: 10.1371/journal.pone.0168580] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2016] [Accepted: 12/02/2016] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Urogenital infection with Chlamydia trachomatis(CT) is one of the most common bacterial sexually transmitted infections (STIs) world-wide, especially in developing nations where routine laboratory diagnosis is unavailable. Little is known about the epidemiology of this infection in Ethiopia where other STIs are prevalent. This study was conducted to determine the prevalence and associated factors of CT infection among women of reproductive age. METHODS A cross-sectional study was conducted among 322 consecutive women aged between 15-49 years at Hawassa University Referral Hospital from November 2014 to April 2015. Data on socio-demography and potential risk factors for genital infection were collected using structured questionnaires. Moreover, endocervical swabs were collected from all participants, screened for CT antigen using rapid immunochromatography assay, and cultured following the standard bacteriological method to isolate Neisseria gonorrhoeae. RESULT In this study, the overall prevalence of CT antigen and N. gonorrhoeae infection was 61(18.9%) and 1(0.31%), respectively. Women aged 15-24 years had the highest prevalence of CT infection (24.2%), followed by those aged 25-34 years (16.8%) and those aged 35-49 years (9.6%). CTinfection was associated with women who had unprotected sex within the last six months (aOR = 3.459; 95% CI = 1.459-8.222) and were sexually active for 6-10 years (aOR = 3.076; 95% CI = 1.152-8.209). None of the clinical symptoms and diagnoses was significantly associated with CT antigen positivity. CONCLUSIONS The high prevalence of genital CT infection in this study highlights the need for further large-scale studies on the general population. Thus, screening of women regardless of their symptoms should be in place.

Abstract
Objectives: To determine the prevalence of Chlamydia trachomatis (C. trachomatis) infection among Saudi women, its clinical presentation, and its association to infertility. Methods: This study was conducted between October 2012 and July 2013 at King Khalid University Hospital and King Abdulaziz University Hospital, Riyadh, Kingdom of Saudi Arabia. Female patients aged between 19 and 46 years old with infertility problems seen at both hospitals were recruited to join the study. A separate group of female patients without infertility problems was also recruited from both hospitals to serve as controls for the study. Endocervical swabs were collected from both groups of patients, and samples were analyzed using real time polymerase chain reaction. Results: There was a statistically significantly greater prevalence of C. trachomatis infection in infertile women (n=8, 8.0%) compared with the fertile group of women (n=1, 1.0%). The C. trachomatis infection was significantly correlated to infertility. Conclusion: A significant association between infertility and increased prevalence of C. trachomatis infection is shown in this study, thus, we suggest that screening for Chlamydial infection to be part of the routine investigation for infertility.
