Evaluation of plasma viral-load monitoring and the prevention of mother-to-child transmission of HIV-1 in three health facilities of the Littoral region of Cameroon.

BACKGROUND: Prevention of mother-to-child transmission (PMTCT) has reduced HIV incidence among new-borns. However, PMTCT remains concerning in sub-Saharan Africa due to bottlenecks including viral load (VL) monitoring during pregnancy. We assessed VL coverage and materno-foetal outcomes of pregnancy among HIV-infected women within the Cameroonian context. METHODS: A hospital-based study was conducted among HIV-infected mothers and their babies in three facilities of the Littoral region of Cameroon from January 2019 to May 2021. Maternal VL-coverage was monitored during pregnancy (VL>1000 copies/ml or unknown were classified as MTCT high-risk group); HIV early infant diagnosis (EID) was evaluated by PCR at six-weeks after birth, and EID results were analysed according to maternal VL; p<0.05 was considered statistically significant. RESULTS: Of 135 HIV-infected pregnant women enrolled (median [IQR] age 39 [27-37] years), VL-coverage during antenatal care (ANC) was 50.4% (68/135), with a lower VL-coverage in 2019 (37.5% vs. 61.9%, p = 0.0069). Married women vs. single (61.8% vs. 42.5%, p = 0.0275) and those on treatment before vs. during pregnancy (56.7% vs. 5.8%, p = 0.0043) had a higher VL-coverage, respectively. Among those with known VL, 10.3% (7/68) had high (VL>1000 copies/mL), 22.1% (15/68) had low (50-1000 copies/mL), and 67.6% (46/68) had undetectable (<50 copies/mL) VL, suggesting an overall viral suppression (<1000copies/mL) of 89.7% (61/68). Vaginal delivery was 80.75% (109/135) regardless of VL, including 81.1% (59/74) women in the high-risk group. EID coverage was 88.1% (119/135) and the rate of HIV-1 MTCT was 1.68% (2/119). Both HIV-positive infants were from the high-risk group, had prolonged labour, had vaginal delivery and were breastfed. CONCLUSION: In these Cameroonian settings, VL-coverage remains suboptimal (below 90%) among ANC attendees, and women at high-risk of MTCT mainly have vaginal delivery. Viral suppression rate remains below the target (below 90%) for accelerating the elimination of MTCT. HIV-MTCT persists, and might be driven essentially by poor VL monitoring. Thus, achieving an optimal PMTCT performance requires a thorough compliance to virologic assessment during ANC.

Prevalence and risk factors associated with precancerous cervical lesions among women in two cities in Cameroon.

Introduction: cervical cancer is the fourth commonest cancer of women world-wide with increasing incidence in developing countries. This study determined the prevalence and assessed risk factors associated with precancerous cervical lesions among women in Cameroon. Methods: this cross-sectional study enrolled 925 women participants of a screening campaign for precancerous cervical lesions from June to November 2018 in the selected hospitals. A convenience sampling technique was used and socio-demographic, sexual and reproductive data collected from consented participants by means of self-administered questionnaire. During the gynaecologic examination, a cervical smear was collected, stained by the Papanicolaou staining technique and the results classified according to the Bethesda 2014 guidelines. Frequency, percentage, Chi square and regression analysis were conducted using SPSS version 20 and p-value considered at 0.05. Results: of the 925 participants aged 25-65 years (mean 40.2±10.2 SD), 113 (12.2%) had the lesions among whom 9 (7.9%) had atypical squamous cells of undetermined significance, 75 (66.4 %) had Low-grade squamous intraepithelial lesion and 29 (25.7%) had high-grade squamous intraepithelial lesion. Factors associated with the lesions were: age 1.85 [1.42-2.41; p= 0.001] and parity [OR= 1.46; 95% CI: 1.30-1.89; P= 0.004]. Conclusion: the prevalence of precancerous lesions was 12.2%. Age, parity were significant risk factors. Regular screening targeting the population at risk in this study becomes a priority.

General versus regional anaesthesia for caesarean section indicated for acute foetal distress: a retrospective cohort study.

BACKGROUND: Acute foetal distress (AFD) is a life-threatening foetal condition complicating 2% of all pregnancies and accounting for 8.9% of caesarean sections (CS) especially in developing nations. Despite the severity of the problem, no evidence exists as to the safest anaesthetic technique for the mother and foetus couple undergoing CS for AFD. We aimed to compare general anaesthesia (GA) versus regional (spinal and epidural) anaesthesia in terms of their perioperative maternal and foetal outcomes. METHODS: We carried out a retrospective cohort study by reviewing the medical records of all women who underwent CS indicated for AFD between 2015 to 2018 at the Douala General Hospital, Cameroon. Medical records of neonates were also reviewed. We sought to investigate the association between GA, and regional anaesthesia administered during CS for AFD and foetal and maternal outcomes. The threshold of statistical significance was set at 0.05. RESULTS: We enrolled the medical records of 117 pregnant women who underwent CS indicated for AFD. Their mean age and mean gestational age were 30.5 ± 4.8 years and 40 weeks respectively. Eighty-three (70.9%), 29 (24.8%) and 05 (4.3%) pregnant women underwent CS under SA, GA and EA respectively. Neonates delivered by CS under GA were more likely to have a significantly low APGAR score at both the 1st (RR = 1.93, p = 0.014) and third-minute (RR = 2.52, p = 0.012) and to be resuscitated at birth (RR = 2.15, p = 0.015). Past CS, FHR pattern on CTG didn't affect these results in multivariate analysis. Adverse maternal outcomes are shown to be higher following SA when compared to GA. CONCLUSION: The study infers an association between CS performed for AFD under GA and foetal morbidity. This, however, failed to translate into a difference in perinatal mortality when comparing GA vs RA. This finding does not discount the role of GA, but we emphasize the need for specific precautions like adequate anticipation for neonatal resuscitation to reduce neonatal complications associated with CS performed for AFD under GA.

Effects of phloroglucinol on the active phase of labour (EPAL trial): a single blinded randomised controlled trial in a tertiary hospital in sub-Sahara Africa.

INTRODUCTION: One of the most recognized factors of maternal and neonatal outcome pertaining to the peripartum period is the duration of labour. Finding a drug that will decrease the duration of labour with no effects on mother and foetus will be welcomed. Thereby in this study we aimed to evaluate the effects of phloroglucinol on the duration of the active phase of labour. METHODS: We did a single blinded placebo controlled randomised 1:1 parallel designed superiority trial between January and June 2017 in Douala general hospital. Participants greater than 18 years with singleton uncomplicated pregnancy who consented following randomisation, were administered either 80mg/8ml intravenous phloroglucinol or 8ml of sterile water when in active labour. The primary outcome was the duration of labour. Modified intention to treat analysis was done with the level of significance set at a p value of 0.05. RESULTS: 122 participants received the intervention. The mean total duration labour in the treatment and placebo group were 216.8 ± 38.7 and 358.5 ± 65.8 respectively (p value = 0.243). The mean duration of the active phase of labour in the treatment and placebo group were 183.0±35.6 and 316.0±52.2 respectively (p value = 0.046). The mean rate of cervical dilatation in the treatment and placebo group were 2.1 ± 0.4 and 1.3 ± 0.4 respectively (p value = 0.322). There was no difference in maternal and foetal outcomes between the two groups. CONCLUSION: Phloroglucinol shortens the duration of active phase of labour by about 2 hours (42%). It is safe to mother and baby and does not cause adverse foetal or maternal outcomes.

Trends and patterns of family planning methods used among women attending family planning clinic in a rural setting in sub-Sahara Africa: the case of Mbalmayo District Hospital, Cameroon.

OBJECTIVE: Family planning enables women to prevent unwanted pregnancies and control family sizes. Provision of family planning services is an essential human right. This study aimed to describe the trends and patterns of contraceptive use in a family planning clinic in a rural district hospital setting. RESULTS: A total 313 participants who used contraceptives between March 2016 and August 2017 were included this study given a. Their mean age was 32.4 ± 1.8 years with an age range of 18-48 years. The index study estimates the rate of contraceptive use at 17.4 contraceptives per month. The most commonly used contraceptive methods were implants and IUD in 29.4 and 28.4% of the participants respectively while the least used was condoms in 8.3% of the participants. Contraceptive used are highest among those 21-40 years (83.1%) and least among adolescents less than 20 years (6.7%).

Knowledge, Attitude, and Practice on Breast Cancer among Health Professionals in Douala References Hospitals, Cameroon.

In Cameroon, patients with breast cancer are more often diagnosed at stage III and IV, hence the need of preventives actions. Knowledge and attitude of medical personnel may influence their practice with regards to screening and early detection of breast cancer. Very few is known about this subject in Cameroon. The objective was to describe the knowledge, attitude, and practice of health care professionals on breast cancer risk factors, diagnostic methods, and screening. This was a cross-sectional study conducted during a 6-month period, among health professionals of Douala General Hospital and Laquintinie Hospital, Cameroon.Data were collected using a self-administered questionnaire which included demographic characteristics, questions on breast cancer risk factors, screening, and diagnostic methods. Marks were attributed to each question and calculated for each section. Participants fell in four categories of knowledge, attitude, and practice: very weak, weak, good, and excellent. The software XLStat7.5.2 was used for data analysis. Overall, 445 health professionals were interviewed. The average age was 39 ± 9 years. The level of knowledge, attitude, and practice was accessed respectively as weak (50.1%), very good (64.5%), and poor (36.4%). The personal practice of female workers was poor (43.0%). Compared to participants with very weak to weak knowledge, those with good to excellent knowledge had 1.55-fold odds of excellent attitude p < 0.0001. After multivariate analysis, the factor associated with good to excellent knowledge was the participant qualification (academic degree). These results suggest the need for training of health professionals in Douala references hospitals on breast cancer risks factors, diagnostic, and screening methods.
