“…Extant literature has documented the intricate relationship between reproductive factors and cervical cancer risk. For instance, Pillai et al [ 11 ] reported in their study that Chlamydia infections significantly increase women’s risk of cervical cancer. Another study conducted in China revealed that lower parity was significantly associated with lower odds of developing cervical cancer while concurrent reproductive tract infections exacerbated the risk of cervical cancer [ 12 ].…”

Introduction Cervical cancer is the second dominant type of cancer among Ivorian women with an estimated age-standardised incidence and mortality rate of 31.2 cases and 22.8 deaths per 100,000 women in 2020, respectively. The Ivorian government through its Ministry of Health implemented the National Cancer Control Programme (NCCP) in 2003 with the aim of improving the prevention, early detection and treatment of cancers in Côte d’Ivoire. Yet, there is a low uptake of CCS (1.2%). Thus, making CCS uptake an important public health concern in the country. Understanding of the extent to which reproductive factors predict CCS uptake is limited in literature. This study aimed to investigate reproductive factors as a predictor of women’s uptake of CCS in Côte d’Ivoire. Methods Data from the 2021 Côte d’Ivoire Demographic and Health Survey. A sample of 9,078 women aged 25–49 years were analyzed. The outcome variable was CCS uptake while other variables considered included age at menarche, history of STI, sexual debut, parity, age, educational level, wealth index, health insurance, place of residence, and media exposure. A multivariable logistic regression model was fitted to examine the association between the outcome of interest and predictors at 95% confidence interval. Results Approximately, 7.52% of women aged 25–49 years had ever undergone testing for cervical cancer by a healthcare provider. Early menarche was associated with lower odds of CCS uptake [AOR = 0.78; CI = 0.65–0.95]. Compared to those who had no STI, women with a history of STI were more likely to screen for cervical cancer [AOR = 2.63; CI = 2.02–3.42]. Increasing age, higher educational attainment, having health insurance, and being exposed to media were significantly associated with CCS uptake. Conclusion In Cote d’Ivoire, age at menarche and STI history constitute reproductive factors that were significantly associated with women’s uptake of CCS. It is imperative for public policy to focus on increasing CCS in these higher-risk women (i.e., women who experienced early menarche, women with early sexual debut and higher parity) through increased sensitization on cervical cancer risk factors.

Murine research has revealed a significant role for antibody responses in protection against Chlamydia reinfection. To explore potential humoral immune markers of protection elicited by Chlamydia trachomatis (CT) antigens in humans in the context of presumed clinical correlates of protection, we used both an IgG1-based ELISA and a conventional total IgG ELISA to evaluate antibody responses. We evaluated responses to five CT outer membrane proteins (PmpE, PmpF, PmpG, PmpH, and MOMP), along with other promising CT antigens (Pgp3 and HSP60), negative control antigens (RecO and AtpE), and CT elementary bodies (EBs) in sera from a well-characterized cohort of 60 women with different CT infection outcomes, including two outcomes that are likely clinical correlates of protective immunity: spontaneous resolution of infection and absence of reinfection after treatment. Furthermore, we used a flow cytometry-based assay to measure antibody-mediated phagocytosis by neutrophils in these sera. Results demonstrated that IgG1 ELISA displayed higher sensitivity than conventional total IgG ELISA in assessing antibody responses to CT EBs and antigens. Pgp3 IgG1 ELISA exhibited the highest sensitivity compared to IgG1 ELISA incorporating CT EBs or other antigens, confirming Pgp3 IgG1 ELISA as an ideal assay for CT antibody detection. Most (95%) sera from women with CT infection outcomes exhibited antibody-mediated phagocytosis of CT EBs, which was significantly correlated with IgG1 antibody responses to MOMP, Pgp3, HSP60, and PmpF. However, neither IgG1 responses to CT antigens and EBs nor antibody-mediated phagocytosis were associated with clinical correlates of protection. These findings suggest that neither CT IgG1 antibody detection nor antibody-mediated phagocytosis will be useful as immune correlates of protection against CT infection in humans.
