Pelvic organ prolapse: a cross-sectional study during mass campaign in two hospitals in the city of Kananga in the Democratic Republic of Congo.

Introduction: pelvic organ prolapse is a dynamic pathology that can worsen or regress especially postpartum and is the basis of several disorders that bother the patient and alter her quality of life. This study aims to determine the epidemiological, clinical, and therapeutic profile of pelvic organ prolapse in the town of Kananga. Methods: this is a cross-sectional study of cases of pelvic organ prolapse recorded during the mass campaign organized in the Bon-Berger Hospital of Tshikaji and Saint Georges Hospital of Katoka in the town of Kananga, from January 1 to July 31, 2023. Non-probability convenience sampling was used to select cases. Results: we recorded 138 cases of prolapse out of 572 patients. The prevalence of pelvic organ prolapse is 24.12% with an average monthly incidence of 19.71 (SD: 4.23) cases per month. The prevalence of recurrence of pelvic organ prolapse is 8.69%. The average age of patients is 54.86 (SD: 11.36) years with an average parity of 7.62 (SD: 1.8) deliveries. Its preoperative symptomatology consists of the intravaginal mass associated with digestive and urinary disorders in 97.00% (n=130), stage III hysterocele predominates in 68.70% (n=92), surgical treatment is the most practiced in 91.79% (n=123) and hysterectomy associated with the treatment of cystocele and rectocele by vaginal surgical access is the most practiced in 80.60% (n=108). Conclusion: pelvic organ prolapse is a real public health problem in the city of Kananga, its symptoms are classic and its treatment is surgical via the vaginal route.

Comparison of human papillomavirus testing and cytology for cervical cancer screening in a primary health care setting in the Democratic Republic of the Congo.

OBJECTIVES: We compared the screening performance of conventional Pap cytology and two human papillomavirus (HPV) DNA assays, the original Hybrid Capture 2 (HC2) and an expanded version that tests for 4 additional HPV types (HC2+4; Qiagen Corporation), in the detection of cervical neoplasia among unscreened women in a primary care setting in a suburb of Kinshasa, Democratic Republic of the Congo. METHODS: All women 30 years or older residing in the area were invited to participate, and 1528 were evaluated by Pap cytology and the two HPV assays, conducted at a European and US reference laboratory, respectively, followed by colposcopy. Cervical biopsies were obtained from all women with abnormal colposcopy and from 290 randomly chosen women with normal colposcopy (to correct for verification bias). RESULTS: Using a relative light unit of 1 as the cutoff for positivity, 169 and 168 (11%) women tested positive using HC2 and HC2+4, respectively. HC2 and HC2+4 were in agreement in 98.6% of cases (Kappa=0.94; 95% confidence interval: 0.91-0.96). Both assays were sensitive (~83%) and specific (~91%) for the detection of cervical intraepithelial neoplasia-2 or worse disease. Irrespective of the cutoff point used to define positivity, Pap cytology was both less sensitive and more specific than HC2 or HC2+4. For instance, cytology was 63% sensitive and 97% specific when a cutoff point of low-grade squamous intraepithelial lesions or worse was used. CONCLUSIONS: Among unscreened women, HC2 and HC2+4 had similar screening accuracy for cervical neoplasia, and both were more sensitive but less specific than Pap cytology.

Association between nausea and vomiting of pregnancy and postpartum depression: the Japan Environment and Children's Study.

OBJECTIVE: Postpartum depression (PPD) is a global emotional distress that affects women and their offspring regardless of their culture. The association between nausea and vomiting of pregnancy (NVP) and PPD has been widely described only for the severe form of NVP. We aimed to assess the relationship between PPD and NVP with regards to its severity. METHODS: Data from the Japan Environment and Children's Study (JECS), a birth cohort study, were analyzed. PPD was assessed using the Edinburgh Postnatal Depression Scale (EPDS). Multiple logistic regression models were performed to assess the association between NVP and PPD. RESULTS: Out of the 80,396 women included in the study 14% had PPD. Among them 4,640 (42.1%) had mild NVP; 3,295 (29.9%) had moderate NVP whereas 1,481 (13.4%) had severe NVP. All forms of NVP were associated with PPD and the association gradually increased with the severity of NVP symptoms with odd ratio (OR): 1.26; 95% confidence interval (CI): 1.18-1.35 for mild, OR: 1.28; 95% CI: 1.19-1.38 for moderate and OR: 1.54; 95% CI: 1.42-1.68 for severe NVP. CONCLUSION: Japanese women with NVP were more susceptible to develop PPD and the more severe the NVP symptoms were, the greater the risk of PPD. Thus, close monitoring of NVP-affected women is recommended.

Prevalence and determinants of high-risk human papillomavirus infection in women from a sub-Saharan African community.

BACKGROUND: Human papillomavirus infection with high-risk types (HR-HPV) is a necessary cause of cervical cancer, the most common malignancy among sub-Saharan African women. Little is known about prevalence of cervical HR-HPV infection in this region. METHODS: A cross-sectional study of 1528 women examined the determinants of HR-HPV infection among women in Kinshasa, Democratic Republic of Congo. Information was collected on sociodemographic, reproductive, lifestyle characteristics, and health-seeking behaviors. Cervical samples were tested for HPV-DNA by Hybrid Capture 2. Unconditional logistic regression identified predictors of HPV positivity. RESULTS: HR-HPV prevalence was 12.5% in all women and 8.7% in women with normal cytology. Prevalence was highest (18.3%) in individuals <35 years of age and gradually decreased with age. Excess HR-HPV infection risk was observed in women who were smokers (odds ratio [OR] = 1.60; 95% confidence interval [CI]: 1.11-2.31), divorced/separated (OR = 1.60; 95% CI: 1.11-2.32), in polygamous marriages (OR = 1.28; 95% CI: 0.90-1.82), using medical contraceptives (OR = 2.40; 95% CI: 1.20-4.80), and who preferred male physicians (OR = 1.90; 95% CI: 1.20-3.05). A statistically marginal increase was found in women whose partners had sex with prostitutes (OR = 2.40; 95% CI: 0.72-8.01). A higher standard of living was associated with reduced risk. CONCLUSION: HR-HPV positivity was associated with behavioral and sexual characteristics thought to affect risk of new infections and immune function. However, HPV prevalence did not correlate with numbers of sex partners, possibly because of a high HPV infection rate per sexual contact or because subjects were older than 30 years. Our study should assist in designing strategies for control of cervical cancer in this low-resource, high cervical cancer risk setting in sub-Saharan Africa.

Factors associated with genital prolapse to Saint Joseph Hospital of Kinshasa.

INTRODUCTION: the aim of this study was to identify factors associated with genital prolapse in the gynecology and obstetrics service of Saint Joseph hospital of Kinshasa. METHODS: this was a retrospective case-control study conducted from 148 medical files of patients admitted in the gynecology and obstetrics service of Saint Joseph hospital from January 1, 2008 to December 31, 2017. It was based on the non-probabilistic sampling of suitability for cases selection. The T-student test, Chi-test and logistic regression were used in statistical analyses. RESULTS: five factors independently associated with genital prolapse were identifying: obesity with BMI≥30Kg/m2(OR: 3.770, 95% CI: 1.040-9.250; p=0.001), menopause (OR: 1.910, 95% CI: 1.090-10.930; p=0.001), fœtal macrosomia (OR: 4.290, 95% CI: 3.320-5.550; p=0.000), vaginal delivery (OR: 2.070, 95% CI: 1.010-5.210; p=0.006) and perineal tears (OR: 1.510, 95% CI: 1.250-1.910; p=0.000). CONCLUSION: these factors independently associated with genital prolapse can be used for screening of high-risk women in gynecological and obstetrical consultations in order to improve the treatment of genital prolapse in our milieu.

Knowledge, attitudes and practices towards menopause among Congolese middle-aged and postmenopausal women.

INTRODUCTION: with the increase in life expectancy, women will live longer during their postmenopausal period. To improve their quality of life, they should be aware of what challenges they will be facing. This study aimed to evaluate the knowledge, attitudes and practices of middle-aged women towards menopause. METHODS: in this cross-sectional study, data collected using a multistage clustered random sampling from 54 health centres in the Democratic Republic of Congo were used. Participants filled a questionnaire derived from the menopause rating scale and from local beliefs. The knowledge, attitudes and practices towards menopause were evaluated among pre- and postmenopausal women. RESULTS: of the 353 women, both pre- and postmenopausal women knew the definition of menopause but for the symptoms, postmenopausal women were more informed than premenopausal. For the attitudes and practices towards menopause, while both had equally positive attitudes, the premenopausal women did not know which practice to adopt. CONCLUSION: Congolese women had limited knowledge, positive attitudes and unconventional practices towards menopause. Health-care providers, therefore, need to dispense appropriate advice to middle-aged women before the advent of menopause.

Genital prolapse: epidemiology, clinic and therapeutic at Saint Joseph Hospital of Kinshasa.

The aim of the study was to describe the epidemiological, clinical and therapeutical profile of genital prolapse in the gynecology and obstetrics service of Saint Joseph Hospital of Kinshasa. This is a descriptive study carried out from medical files of patients who have suffered from genital prolapse in the gynecology and obstetrics service of Saint Joseph Hospital from January 1st, 2008 to December 31st, 2017. It is based on the no probabilistic sampling of suitability. We recorded 161 cases of genital prolapses upon 13957 patients. The genital prolapses frequency was 1.2% with an annual average of 16.1 cases (SD 10.1) per year. The symptomatology consisted of pelvic mass associated with urinary and digestives troubles (94.0%, n=140). The stage III of cysto-colpocele was the most frequent (56.0%, n=82). The vaginal hysterectomy associated to rectocele and cystocele cure was the most performed operation (52.0%, n=69). The recurrence rate was of 2.0% (3 out of 148 cases). The genital prolapse really exist in our milieu, its symptomatology is classical and its treatment is mostly surgical by vaginal access.

Impact of antiviral AV2 in the topical treatment of HPV-associated lesions of the cervix: Results of a phase III randomized placebo-controlled trial.

BACKGROUND: Non-surgical topical therapies have been assessed in the treatment of precancerous lesions of the cervix. Their use can offer logistical and feasibility advantages in low-resource settings. Antiviral AV2® is a mixture of natural essential oils (eugenol, carvone, nerolidol, geraniol) in olive oil, and has a broad spectrum anti-viral activity. In a phase II randomized controlled trial (RCT), AV2® proved effective in reducing the size of cervical lesions associated with human papillomavirus (HPV). The purpose of the present study was to further evaluate the efficacy of AV2 over placebo in the topical treatment of HPV-associated cervical lesions. METHODS: Women aged 25 years and older were included in this phase 3 RCT. Cytology screening, HPV testing and visual inspection of the cervix with 5% acetic acid (VIA) were performed on all participants. VIA-positive women were randomized to one of two groups to receive treatment by either AV2® or placebo. The treatment consisted of 2 puffs of spray of the investigational drug directed to the cervix. Participants were subjected to repeat examinations two months and six months later for assessment of outcomes. The primary outcome was the change of lesions on VIA at 2 months after application of the investigational drug. Secondary outcomes were: HPV clearance and cytologic regression at 2 months and 6 months, and number of participants with AEs. RESULTS: A total 327 VIA positive women were randomized in two groups (168 in AV2 group and 159 in placebo group). Women in the 2 groups were similar with respect to baseline demographics and clinical characteristics. At 2 months, regression of lesions on VIA was observed in 127 (89.4%) out of 142 women in AV2 group compared to 120 (91.6%) out of 131 women in placebo group (P = 0.7). On cytology, regression of lesions occurred in 14 (56%) out of 25 women in the AV2 arm and in 13 (48.1) out of 27 women in the placebo arm (p = 0.7), and HPV clearance rates were 34.1% and 35% in AV2 group and placebo group respectively (p = 0.8). At 6 months cytologic regression was observed in 64.7% of women in AV2 group and 45.8% in placebo group (p = 0.2), while HPV clearance occurred in 11 (51.9%) out of 17 women in AV2 arm versus 11 (34.4%) in placebo arm (p = 0.3).Some local side effects (burning, itching, irritation) were similarly noted in the 2 groups (p-values = 0.169, 0.623 and 0.172 respectively) but they were mild and transitory. CONCLUSION: A topical application of AV2 onto the cervix can induce the regression of cervical precancerous lesions, but its efficacy does not significantly differ with that of placebo. The discrepancy between the expected and the recorded sample size as well as the huge number of lost to follow-up probably impeded the power of analyses, which could be one of the reasons for the lack of difference seen between AV2 and placebo. Further evaluation of the effects of AV2 with different diagnostic methods and treatment regimen and arms is warranted. CLINICAL TRIAL REGISTRATION: NCT02346227 registered on November 8, 2014.

Efficacy of commercially available biological agents for the topical treatment of cervical intraepithelial neoplasia: a systematic review.

BACKGROUND: Cervical cancer is a major public health issue in the world, especially in developing countries. It can be prevented through vaccination against HPV (primary prevention) and through screening and treatment of cervical intraepithelial neoplasia (CIN) (secondary prevention). Surgical methods for treatment of CIN are linked to complications such as bleeding and adverse pregnancy outcomes. Furthermore, these methods are not generally available in resource-poor settings. Therefore, topical agents for local application on the cervix have been used since decades to overpass complications and limitations of the surgical methods. AIMS: Review of the literature on the efficacy of commercially available biological agents used for topical treatment of cervical intraepithelial neoplasia (CIN). METHODS: A systematic search through PubMed and the Cochrane database was performed up to December 2017, using the medical subheadings (MesH) for topical agent, treatment, and cervical intraepithelial neoplasia. Appropriate inclusion/exclusion criteria have been used for the selection of eligible clinical studies. Clinical studies containing a minimum of 20 women, aged 18-50 with a diagnosis of CIN 1-3, and at least a 4 weeks follow-up after the end of the topical treatment were included. RESULTS: The initial electronic database search resulted in a total of 849 articles. After screening titles and abstracts, 62 articles were selected as potential studies. Of these, six articles were included in the review after reading the full text: two were on 5-FluoroUracil, two on trans retinoic acid, one on Imiquimod, and one on Cidofovir. The reported regression/remission rates for CIN differed among studies. In CIN2 patients, the overall remission rate ranged between 43 and 93% for the active agents. CONCLUSION: Among the topical agents studied, 5-FluoroUracil showed good remission rates above 80%. Varying results seen in this review is due to the differences in quality of the design between studies. Large-scale and less biaised studies are needed to elucidate the true efficacy and safety of topical agents in the treatment of CIN.

Prevalence and Distribution of Human Papillomavirus Genotypes Among Women in Kinshasa, The Democratic Republic of the Congo.

PURPOSE: Cervical cancer is the leading cause of mortality by cancer in sub-Saharan Africa. The human papillomavirus (HPV) infection is recognized as a necessary and sufficient cause for cervical cancer. Population-specific estimates of HPV prevalence in the Democratic Republic of the Congo (DRC) are unknown. This study aims to estimate the prevalence of HPV and identify predominant genotypes circulating in Kinshasa, DRC. METHODS: Between July 2015 and July 2017, women were invited to attend a screening program at Mont-Amba Health Centre in Kinshasa. Cervical specimens were collected using the Preservcyt medium. HPV DNA testing was performed for all specimens using real-time polymerase chain reaction. RESULTS: During the 2-year period, a total of 1,870 women age 25 to 82 years were screened. The mean age was 46 years (± 11.4 years). The overall HPV prevalence was 28.2% (95% CI, 26.1% to 30.3%). High-risk HPV prevalence was 24.8% (95% CI, 22.8% to 26.8%). Women younger than 30 years had the highest overall HPV prevalence (42.2%; 95% CI, 34.7% to 49.9%). A second peak of prevalence was observed in women age 60 years and older. HPV68 (5.5%; 95% CI, 4.5% to 6.6%) was the most prevalent HPV type. CONCLUSION: The distribution of HPV genotypes among women in our population was different compared with other world regions. A key finding was that HPV68 was the most prevalent high-risk HPV genotype. These findings highlight the need for the determination in our population of the etiologic fraction of different HPV types in invasive cervical cancers.

Morphometric semi-quantitative assessment of vertebral fractures in postmenopausal black women in Central Africa.

This prospective and multi-centric study assessed the lacking of pattern in fractured patients and features of vertebral fractures in postmenopausal black women living in central Africa. INTRODUCTION: Patients with osteoporosis commonly collapsed their vertebral body. This has been widely studied in Caucasians, Asians, and Americans and studies in black African are lacking. Our study was designed to establish a pattern of patients with fractures and determine the features of vertebral fractures in postmenopausal black women living in Central Africa. METHODS: A prospective and multi-centric study was conducted from June 2011 to June 2016, to assess the thoraco-lumbar-computed tomographic images of women. The menopausal statuses and anthropometric parameters (age, height, and weight) were collected. The body mass index and the Asset Poverty Index were evaluated. The reviews included a morphometric analysis of each vertebra that was rated according to the visual semi-quantitative system proposed by Genant et al. RESULTS: Four hundred thirty women aged 47-87 years old were included in this study. The mean age was 57 years old, and the mean menopause duration was 11.45 ± 6.6 years with extremes ranging from 2 to 37 years. The body mass indices were rated as overweight and obese in 80.8% of subjects and 54, 3% had high-API indices. Among the 4730 vertebrae analyzed, 529 (11.12%) were fractured, with 68.7% exhibited a cup-shaped deformation (biconcave), 19.8% had a wedge-shaped deformation, and 11.4% exhibited a cake (crush) deformation. Of the vertebras, 88.8% were grade 0, 5.5% grade 1, 5% grade 2, and 0.57% were grade 3. Of the women, 68.8% had one vertebra fractured and 31.2% had more than one fractured vertebrae. CONCLUSION: This study seemed to determine the pattern and features of vertebral fractures in black African women which may be useful for comparisons with the pattern of worldwide populations.

Efficacy of antiviral drug AV2 in the treatment of human papillomavirus-associated precancerous lesions of the uterine cervix: A randomized placebo-controlled clinical trial in Kinshasa, DR Congo. (KINVAV study).

BACKGROUND: Cervical Cancer (CC) is a major public health problem in DR Congo; the high incidence of CC is due to the inexistence of effective screening programs based on cytology and/or HPV detection followed by appropriate treatments. This situation highlights the need to implement efficacious and inexpensive treatment methods. This study aims at evaluating the efficacy of a topical antiviral drug named AV2® as a treatment for HPV-associated lesions of the cervix. METHODS: Women will undergo cytology sampling, HPV testing and Visual inspection of the cervix after application of 5% acetic acid (VIA). VIA-positive women will be randomized to one of two groups to receive treatment by either AV2®or placebo. They will undergo control examinations after two months and after six months. In case of persistent lesions on VIA, treatment by cryotherapy will be done. The primary outcomes will be the change of lesions, the clearance of HPV DNA, and the correlation of the two 2 months after treatment with AV2®. CONCLUSION: This study is the first large-scale study in Africa to evaluate systematically the efficacy and safety of a topical antiviral drug for the treatment of HPV- associated lesions of the cervix. Its findings will direct the planning of suitable algorithms for CC screening and treatment.

Preconception gynecological risk factors of postpartum depression among Japanese women: The Japan Environment and Children's Study (JECS).

BACKGROUND: Postpartum depression is one of the major causes of disability among women who are on their childbearing years. Identifying people at risk of postpartum depression may improve its management. The objective of this study was to determine the probable association between postpartum depression and some preconception gynecological morbidities. METHODS: Data from a nationwide birth cohort study, the Japan Environment and Children's study (JECS), up to one month of postpartum were analyzed. To assess postpartum depression, the Edinburgh Postnatal Depression Scale (EPDS) was used; 11 preconception gynecological morbidities were considered as risk factors. Covariates included psychiatric illness history, psychosocial factors, some pregnancy adverse outcomes, birth outcomes, socio-demographic and health behavioral factors. RESULTS: Except for the prevalence of previous miscarriage, leiomyoma and polycystic ovarian syndrome, depressive women had more gynecological morbidities compared to non-depressive ones. In logistic regression model, endometriosis (OR, 1.27; 95%CI: 1.15-1.41), dysmenorrhea (OR, 1.13; 95%CI: 1.06-1.21) and abnormal uterine bleeding (OR, 1.21; 95%CI: 1.15-1.29) were associated with postpartum depression. LIMITATIONS: CONCLUSION: Women with endometriosis and menstrual problems were at risk of developing postpartum depression. This study suggests a perinatal mental health screening for predisposed women.

Visual inspection as a cervical cancer screening method in a primary health care setting in Africa.

We evaluated the feasibility and performance of visual inspection with acetic acid (VIA) and Lugol's iodine (VILI) for cervical cancer screening in a primary health-care setting in Kinshasa, Congo. Women (1,528) aged > or =30 years were screened independently by nurses and physicians by VIA and VILI and Pap cytology. Biopsy samples were obtained from women with abnormal colposcopies and from 290 randomly chosen women with normal colposcopy. Cytological and histological examinations were performed in Lyon and Montreal, respectively. The prevalence of cervical intraepithelial neoplasia (CIN) of grades 1, 2 and 3 was 4.5, 1.3 and 4%, respectively. Using biopsy as the reference, the sensitivity, specificity and negative predictive value (NPV) for > or =CIN 2 for VIA-nurse were 55.5% (95% CI: 34.7-76.2), 64.6% (95% CI: 62.0-67.1) and 96.8% (95% CI: 93.5-98.7), respectively. The corresponding values for VILI-nurse were 44.0% (95% CI: 24.2-63.8), 74.6% (95% CI: 72.3-76.9) and 96.7% (95% CI: 93.7-98.6). The equivalent parameters for physicians were 71.1% (95% CI: 46.7-95.5), 71.3% (95% CI: 68.9-73.6) and 98.6% (95% CI: 96.0-99.7) for VIA and 68.3% (95% CI: 42.5-94.0), 76.2% (95% CI: 74.0-78.4) and 97.2% (95% CI: 95.3-98.5) for VILI. The sensitivity of cytology ranged between 31 and 72%, depending on the abnormality threshold used to define positivity, with a corresponding specificity range of 94-99% and a NPV range of 97-99%. Our results show that VIA and VILI performed by nurses and physicians are slightly more sensitive but less specific than Pap cytology across multiple combinations of test and lesion thresholds. Given their lower cost and easy deployment, visual inspection methods merit further assessment as cervical cancer screening methods for low-resource countries.
