Proactive home-based malaria management in rural communities of Bassar Health District in northern Togo from 2014 to 2017: PECADOM + , a pilot experiment.

BACKGROUND: Togo's National Malaria Control Programme has initiated an active home-based malaria management model for all age groups in rural areas of Bassar Health District. This report describes the model, reports its main results, and determines the factors associated with positive rapid diagnostic test results. METHODS: From 2014 to 2017, in three peripheral care units of Bassar Health District (Binaparba, Nangbani, and Baghan), community health workers visited residents' homes weekly to identify patients with malaria symptoms, perform rapid diagnostic tests in symptomatic patients, and give medication to positive cases. Univariate and multivariate logistic regression models were used to determine the factors associated with positive tests. RESULTS: The study covered 11,337 people (817 in 2014, 1804 in 2015, 2638 in 2016, and 6078 in 2017). The overall mean age was 18 years (95% CI 5-29; min-max: 0-112 years). The median age was 10 years (SD: 16.9). The proportions of people tested positive were 75.3% in Binaparba, 77.4% in Nangbani, and 56.6% in Baghan. The 5-10 age group was the most affected category (24.2% positive tests). Positive tests were more frequent during the rainy than during the dry season (62 vs. 38%) and the probability of positive test was 1.76 times higher during the rainy than during the dry season (adjusted OR = 1.74; 95% CI 1.60-1.90). A fever (37.5 °C or higher) increased significantly the probability of positive test (adjusted OR = 2.19; 95% CI 1.89-2.54). The risk of positive test was 1.89 times higher in passive than in active malaria detection (adjusted OR = 1.89; 95% CI 1.73-2.0). CONCLUSIONS: This novel experimental community and home-based malaria management in Togo suggested that active detection of malaria cases is feasible within 24 h, which allows rapid treatments before progression to often-fatal complications. This PECADOM + program will help Togo's National Malaria Control Programme reduce malaria morbidity and mortality in remote and hard-to-reach communities.

Any resurgence of leprosy cases in the Togo's post-elimination period? Trend analysis of reported leprosy cases from 2010 to 2022.

BACKGROUND: Leprosy, or Hansen's disease, is a chronic infectious disease caused by Mycobacterium leprae. Togo achieved the target of eliminating leprosy as a public health problem in 2000 (less than 1 case/10 000 population). However, new cases of leprosy are still being reported. The aim of this study was to describe and map trends of leprosy cases notified in Togo from 2010 to 2022. METHODS: This was a descriptive cross-sectional study covering a thirteen-year period from January 1, 2010, to December 31, 2022. The data of the study were leprosy surveillance system's data collected monthly between 2010 and 2022. The estimated number of leprosy cases and the incidence rate of leprosy cases were reported for the whole population by region, by district, by calendar year (2010-2022) and by target sub-population (children under 15, women and people with disabilities). Observed case incidence rates were mapped by health district and by year. RESULTS: From January 1, 2010, to December 31, 2022, 1031 new cases of leprosy were diagnosed in Togo. The median age of subjects was 46 years (interquartile range: 33-60), with extremes from 4 to 96 years. Half the subjects were women (50.7%). Variations in the leprosy incidence rate by year show an increase between 2010 and 2022, from 0.7 cases /100,000 population to 1.1 /100,000 population respectively. From 2010 to 2022, the proportion of cases in children remained low, between 0 and 9%. The proportion of women fluctuated between 39.7% and 67.2% between 2010 and 2017, then stabilized at an average of 50% between 2018 and 2022. The proportion of multi-bacillary leprosy cases increased quasi-linearly between 2010 and 2022, from 70 to 96.6%. Mapping of leprosy cases showed that leprosy was notified in all Togo health districts during the study period, apart from the Lacs district, which reported no leprosy cases. CONCLUSION: Togo has achieved the elimination of leprosy as a public health problem. However, the increase in the number of new leprosy cases and the proportion of leprosy cases in children indicate that transmission of the disease is continuing and that supplementary measures are needed.

'We had to be there, Present to Help Him': Local Evidence on the Feeling of Safety in End-of-Life Care in Togo.

Objectives: For patients with diabetes and cancer at the end-of-life and their families, the safety sought in end-of-life care leads them to opt for home care. In developing countries where palliative care is not yet effectively integrated into public health policies, factors such as long distances to hospital referrals, lack of adequate infrastructure and shortage of specialised health professionals create a sense of insecurity for people seeking end-of-life care. The present study explored the factors that reinforce the feeling of security and insecurity of family members who have opted to accompany their relatives with diabetes and/or advanced cancer at the end-of-life at home in Togo. Materials and Methods: This was an ethnographic approach based on observations and in-depth semi-structured interviews with people with the following characteristics: family members (bereaved or not) with experience of caring for a patient with diabetes and cancer at home at the end-of-life. The data were analysed using content and thematic analysis. This was done to identify categories and subcategories using the qualitative analysis software Nvivo12. Results: The results show that of the ten relatives interviewed, eight had lived with the patient. Factors contributing to the feeling of security in the accompaniment of end-of-life care at home by the family members were, among others: 'Informal support from health-care professionals,' 'social support' from relatives and finally, attitudes and predispositions of the family members (presence and availability to the patient, predisposition to respect the patient's wishes at the place of end-of-life care and predisposition to talk about death with the dying person). Conclusion: The 'informal support of health-care professionals', the 'perception of the home as a safe space for end-of-life care' and the 'social support' of family members contributed most to the feeling of safety among family members accompanying their diabetic and cancer patient family members at the end-of-life at home in Togo. Therefore, palliative and end-of-life care must be rethought in public health policies in Togo to orientate this care toward the home while providing families/caregivers with the knowledge and tools necessary to strengthen care.

Use of gynaecological care by young women in Togo: focus on students and analysis of the determinants at the University of Lomé.

OBJECTIVES: The study aims to gain a better understanding of the needs and health behaviours of young women at the University of Lomé (Togo) with regard to gynaecological care. STUDY DESIGN: The data comes from a self-administered online survey. METHODS: A logistic regression was applied to model the likelihood of non-use of gynaecological care. RESULTS: Among the 281 women who completed the survey, 75% declared they had not consulted a gynaecologist or healthcare professional for a question related to intimacy or contraception in the last 12 months, mainly because of the financial barrier (65%). But needs do exist as 73% of women would like to be able to consult for such reasons. Multivariate analysis shows that increasing age (21-24 years, odds ratio [OR] = 0.442, P value < 0.05); 25-33 years, OR = 0.190, P value < 0.001), practicing Christian religion (OR = 0.331, P value < 0.1), being insured (OR = 0.398, P value < 0.05), having a father with primary education level (OR = 0.320, P value < 0.05) were protective factors. In contrast, the size of the households [6-8 members, OR = 2.763, P value < 0.1), and the student's income (Q2, OR = 3.136, P value < 0.05; Q3, OR = 2.993, P value < 0.05; Q4, OR = 4.433, P value < 0.001) favoured a higher probability of non-use of gynaecological care. CONCLUSION: Gynaecological needs are real among young women, and gynaecological health promotion is a necessity among this cohort. Quality health promotion can be achieved practically through the enlargement of health insurance, and partnership with healthcare professionals as well as community/religious leaders. This would further demystify biases related to seeking gynaecological care.

Epidemiology of alcohol use disorder in the general population of Togo and Benin: the ALCOTRANS study.

INTRODUCTION: Access to data concerning mental health, particularly alcohol use disorders (AUD), in sub-Saharan Africa is very limited. This study aimed to estimate AUD prevalence and identify the associated factors in Togo and Benin. METHODS: A cross-sectional study was conducted between April and May 2022, targeting individuals aged 18 years and above in the Yoto commune of Togo and the Lalo commune of Benin. Subjects were recruited using a multi-stage random sampling technique. AUD diagnoses were made using the MINI adapted to DSM-5 criteria. Our study collected sociodemographic information, data on psychiatric comorbidities, stigmatization, and assessed cravings, using a series of scales. The association between AUD and various factors was analyzed using multivariable logistic regression. RESULTS: In Togo, 55 of the 445 people investigated had AUD (12.4%; [95% CI: 9.5-15.7%]). Among them, 39 (70.9%) had severe AUD and the main associated comorbidities were suicidal risk (36.4%), and major depressive disorder (16.4%). Associated factors with AUD were male gender (aOR: 11.3; [95% CI: 4.8-26.7]), a higher Hamilton Depression Rating Scale (HDRS) score (aOR: 1.2; [95% CI: 1.1-1.3]) and a lower Stigma score measured by the Explanatory Model Interview Catalogue (EMIC) (aOR: 0.9; [95% CI: 0.8-0.9). The stigma scores reflect perceived societal stigma towards individuals with AUD. In Benin, 38 of the 435 people investigated had AUD (8.7%; [95% CI: 6.4-11.7]), and the main associated comorbidities were suicidal risk (18.4%), tobacco use disorder (13.2%) and major depressive episode (16.4%). Associated factors with AUD were male gender (aOR: 6.4; [95% CI: 2.4-17.0]), major depressive disorder (aOR: 21.0; [95% CI: 1.5-289.8]), suicidal risk (aOR: 3.7; [95% CI: 1.2-11.3]), a lower Frontal Assessment Battery (FAB) score (aOR:0.8; [95% CI: 0.8-0.9]) and a lower perceived stigma score (by EMIC )(aOR: 0.9; [95% CI: 0.8-0.9]). CONCLUSION: In these communes of Togo and Benin, AUD prevalence is notably high. A deeper understanding of the disease and its local determinants, paired with effective prevention campaigns, could mitigate its impact on both countries.

Knowledge, attitudes, and practices of health care professionals regarding dengue fever: need for training and provision of diagnostic equipment in Togo in 2022, a cross-sectional study.

Background: Health statistics on dengue are virtually non-existent, despite the fact that the virus is circulating in Togo. This study aimed to assess the knowledge, attitudes, and practices (KAP) of health professionals in the Kara health region. Methods: A cross-sectional study was conducted from March to June 2022 among healthcare professionals who had worked in the Kara region of northern Togo were selected using an exhaustive recruitment method. Data were collected by trained resident doctors with a face-to-face interview using a standardized, pretested questionnaire based on the WHO 2009 dengue guide. Three multivariate regression models were utilized to investigate factors associated with knowledge, attitudes and, and practices. Results: A total of 464 respondents (37.1% female), median age 35 years, interquartile range (29-43 years) were included. Only (3.0%) of the participants had received training on dengue fever diagnosis, treatment and prevention in the last 3 years, and 10.3% had dengue rapid diagnostic tests available at their hospital. Half of the respondents (49.1%) had good knowledge of dengue fever, compared with 30.0% who had positive attitudes. Of a total of 256 professionals who had encountered a case of dengue fever in their practice, only 24 (9.4%) had appropriate practices for diagnosing and treating dengue fever. In multivariate analysis, the healthcare professionals who had taken part in ongoing training on dengue fever were more likely to have adequate dengue diagnosis and treatment practice aOR = 8.1; CI 95% = [1.7-36.0]. Conclusion: Strengthening healthcare professionals' dengue-related skills through ongoing training and the provision of dengue diagnostic tests could help improve early detection practices and management of dengue fever in Togo.

Pharmaco-virological outcomes and genotypic resistance profiles among children and adolescents receiving a DTG-based regimen in Togo.

BACKGROUND: Few data are available on the real-world efficacy of receiving tenofovir-lamivudine-dolutegravir (DTG) as HIV treatment, particularly among young people in West Africa. Here, we evaluated pharmaco-virological outcomes and resistance profiles among Togolese children and adolescents. METHODS: A cross-sectional study was conducted in Lomé, Togo, enrolling antiretroviral-treated people with HIV aged from 18 months to 24 years. Plasma HIV-1 viral load and antiretroviral concentrations were measured. Next-Generation Sequencing (NGS) of protease, Reverse Transcriptase (RT) and integrase was performed on all samples with viral load >200 c/mL. Drug resistance mutations (DRMs) were identified and interpreted using the ANRS-MIE algorithm. RESULTS: 264 participants were enrolled (median age=17 years), 226 received a DTG-based regimen for a median of 20.5 months. Among them, virological suppression at the 200 c/mL threshold in 80.0% of the participants. Plasma DTG concentrations were adequate (i.e., >640 ng/mL), suboptimal and below the limit of quantification in 74.1%, 6.7% and 19.2% of participants receiving DTG, respectively. Overall, viruses resistant to any of Nucleoside RT Inhibitors, Non-NRTIs, and protease inhibitors were found in 52%, 66% and 1.6% of participants, respectively. A major integrase inhibitor DRM was observed in 9.4% (n=3/32, R263K, E138A-G140A-Q148R, and N155H) of participants with a viral load >200 c/mL. CONCLUSIONS: These first findings in such a large series of adolescents in a low-income country, showed a good virological response of 80% and the presence of an integrase DRM in 9.4% of the virological failures, supporting the need to monitor DTG drug resistance to reduce the risk of resistance acquisition.

Epidemiological, clinical, therapeutic and evolutionary specificities of the association between venous thromboembolic event and cancer in sub-Saharan Africa: Case of Togo.

BACKGROUND: Our study aimed to describe the clinical, paraclinical, therapeutic and outcomes of patients with venous thromboembolic event (VTE) associated with cancer in the context of limited resources. MATERIALS AND METHODS: This was a descriptive cross-sectional study over a period of six years from March 1, 2016 to March 31, 2022, in the cardiology department and the oncology unit of the Sylvanus Olympio Teaching Hospital of Lome. Our study examined medical records of patients who were at least 18 years old and had venous thromboembolic disease and cancer that was histologically confirmed. This study did not include records that were incomplete or records from patients with coronavirus disease. RESULTS: Our study included 87 patients with average age of 56.36±15.26 years. The discovery of VTE occurred incidentally in 28.74%. Venous thrombosis was isolated in 68.96% and proximal in 95%. Pulmonary embolism was bilateral in 77.77%. Gynaecological and urological cancers were found in 33.33% and 32.19% respectively. Adenocarcinoma was the histological type of cancer found in 47.13%. Cancers were at a very advanced stage in 74.71%. Treatment with antivitamin K was prescribed in 12.65%. In our study, there were 58 patients who passed away with a mortality rate of 66.66%. The cause of death was a complication of VTE in 22.42% and related to the course of cancer in 63.79% of cases. CONCLUSION: VTE during cancer is particular with a fatal evolution due to the severity of VTE and the very advanced stage of cancer.

Efficacy of artemether-lumefantrine and dihydroartemisinin-piperaquine and prevalence of molecular markers of anti-malarial drug resistance in children in Togo in 2021.

BACKGROUND: Artemether-lumefantrine (AL) and dihydroartemisinin-piperaquine (DP) are the currently recommended first- and second-line therapies for uncomplicated Plasmodium falciparum infections in Togo. This study assessed the efficacy of these combinations, the proportion of Day3-positive patients (D3 +), the proportion of molecular markers associated with P. falciparum resistance to anti-malarial drugs, and the variable performance of HRP2-based malaria rapid diagnostic tests (RDTs). METHODS: A single arm prospective study evaluating the efficacy of AL and DP was conducted at two sites (Kouvé and Anié) from September 2021 to January 2022. Eligible children were enrolled, randomly assigned to treatment at each site and followed up for 42 days after treatment initiation. The primary endpoint was polymerase chain reaction (PCR) adjusted adequate clinical and parasitological response (ACPR). At day 0, samples were analysed for mutations in the Pfkelch13, Pfcrt, Pfmdr-1, dhfr, dhps, and deletions in the hrp2/hrp3 genes. RESULTS: A total of 179 and 178 children were included in the AL and DP groups, respectively. After PCR correction, cure rates of patients treated with AL were 97.5% (91.4-99.7) at day 28 in Kouvé and 98.6% (92.4-100) in Anié, whereas 96.4% (CI 95%: 89.1-98.8) and 97.3% (CI 95%: 89.5-99.3) were observed at day 42 in Kouvé and Anié, respectively. The cure rates of patients treated with DP at day 42 were 98.9% (CI 95%: 92.1-99.8) in Kouvé and 100% in Anié. The proportion of patients with parasites on day 3 (D3 +) was 8.5% in AL and 2.6% in DP groups in Anié and 4.3% in AL and 2.1% DP groups in Kouvé. Of the 357 day 0 samples, 99.2% carried the Pfkelch13 wild-type allele. Two isolates carried nonsynonymous mutations not known to be associated with artemisinin partial resistance (ART-R) (A578S and A557S). Most samples carried the Pfcrt wild-type allele (97.2%). The most common Pfmdr-1 allele was the single mutant 184F (75.6%). Among dhfr/dhps mutations, the quintuple mutant haplotype N51I/C59R/S108N + 437G/540E, which is responsible for SP treatment failure in adults and children, was not detected. Single deletions in hrp2 and hrp3 genes were detected in 1/357 (0.3%) and 1/357 (0.3%), respectively. Dual hrp2/hrp3 deletions, which could affect the performances of HRP2-based RDTs, were not observed. CONCLUSION: The results of this study confirm that the AL and DP treatments are highly effective. The absence of the validated Pfkelch13 mutants in the study areas suggests the absence of ART -R, although a significant proportion of D3 + cases were found. The absence of dhfr/dhps quintuple or sextuple mutants (quintuple + 581G) supports the continued use of SP for IPTp during pregnancy and in combination with amodiaquine for seasonal malaria chemoprevention.

Epidemiological and virological surveillance of the prevention of mother-to-child transmission of HIV among pregnant women in Togo.

BACKGROUND: In 2015, Togo introduced the "test-and-treat" strategy for the prevention of mother-to-child transmission (PMTCT) of HIV. Pediatric HIV infection remains a public health problem in Togo, with a mother-to-child transmission (MTCT) rate of 3.6% in 2020. This study aimed to estimate cases of HIV seroconversion during pregnancy and to identify pregnant women at high risk of transmitting HIV to their children in Lomé, Togo. METHODS: A descriptive cross-sectional study was carried out from 18 March to 22 May 2022 among women who had given birth in five maternity units providing PMTCT services in Lomé. Umbilical cord blood samples were taken from the maternal side by midwives after delivery. HIV serology was performed in the laboratory using the Alere™ HIV Combo SET and First Response HIV 1-2. Card Test version 2.0. A sample was considered positive if both tests were positive. The HIV-1 viral load in HIV-1-positive samples was measured using Cobas/Roche 4800 equipment. Information on the women was extracted from maternal antenatal records and antenatal consultation registers. RESULTS: A total of 3148 umbilical cord blood samples (median maternal age: 28 years (interquartile range [24-32]) were collected. Among them, 99.3% (3145/3148) had presented for at least one antenatal clinic visit before giving birth, and 78.7% (2456/3122) had presented for at least four visits. One hundred and twenty-one (121) cord samples were HIV-1 positive, representing a seroprevalence of 3.8% (95% CI = [3.2-4.6]). Among them, 67.8% (82/121) were known HIV-positive before the current pregnancy, 29.7 (36/121) were diagnosed as HIV-positive at the antenatal visits and 2.5% (3/121) were diagnosed as HIV-positive in the delivery room. Of the HIV-positive women, 85.9% (104/121) were on ARV treatment before delivery. The viral load was < 1000 copies/ml in 97.5% (118/121) cases. CONCLUSION: This study explored the virologic and epidemiological aspects of HIV among pregnant women in Togo. The results show significant viral suppression at delivery in women ART. Surveillance based on umbilical cord blood specimen screening is an interesting approach for monitoring the effectiveness of PMTCT programmes.

Alcohol to-go sales policies at on-premise drinking establishments near large public US universities during the COVID-19 pandemic.

AIMS: Sweeping policy changes during the COVID-19 pandemic increased alcohol availability through permitted to-go sales, potentially posing unique risks to college students. While to-go sales may make binge drinking more convenient, little remains known about these practices. Therefore, this study aimed to assess whether drinking establishments' to-go sales practices are associated with their other operational practices and state policy. METHOD: This cross-sectional analysis included 221 randomly selected bars, nightclubs, and restaurants within two miles of a large public university. Telephone interviews assessed establishment practices, and the Alcohol Policy Information System provided state alcohol to-go laws. Regression models tested whether establishment to-go sales practices were associated with their business practices (logistic regression) and state policy (generalized estimating equations). RESULTS: Nearly one-half (44.8%) of drinking establishments sold alcohol to-go. Establishments with higher vodka prices had nearly 30% higher odds of selling spirits to-go (aOR = 1.29) and establishments offering happy hours specials had more than twice the odds of selling beer (aOR = 2.22), wine (aOR = 2.53), and spirits to-go (aOR = 2.60). Additionally, establishments that implemented physical distance requirements had higher odds of selling wine to-go (aOR = 3.00). State to-go laws were associated with higher odds of selling wine (aOR = 3.99) and spirits to-go (aOR = 5.43) in the full sample and beer to-go (aOR = 4.92) in urban counties. CONCLUSIONS: Establishments that sell alcohol to-go tend to engage in other practices designed to drive sales. Evaluations of alcohol to-go sales laws on risky consumption among priority populations, including college students, are urgently needed to inform decisions about how to appropriately regulate sales.

Effectiveness of Sensitization Campaigns in Reducing Leprosy-Related Stigma in Rural Togo: Protocol for a Mixed Methods Cluster Randomized Controlled Trial.

BACKGROUND: In the global strategy to eliminate leprosy, there remains a need for early case detection to successfully interrupt transmissions. Poor knowledge about leprosy and leprosy-related stigma are key drivers of delayed diagnosis and treatment. Sensitization campaigns to inform and increase awareness among the general population are an integral part of many national neglected tropical disease programs. Despite their importance, the effectiveness of such campaigns has not been rigorously studied in the West African context. A multilingual rural setting with low health literacy in this region presents challenges to the potential impact of sensitization campaigns. OBJECTIVE: The primary objective of this study is to assess the causal effect of common practice community sensitization campaigns on leprosy-related knowledge and stigma at the community level and among community health volunteers. Additionally, we will test the potential of novel educational audio tools in the 15 most prominent local languages to overcome literacy and language barriers and amplify sensitization campaigns. METHODS: We will conduct a cluster randomized controlled trial using a sequential mixed methods approach in 60 rural communities across all regions of Togo, West Africa. The study features 2 intervention arms and 1 control arm, with intervention and control assignments made at the community level through randomization. Communities in intervention arm 1 will receive a sensitization campaign in line with the current Togolese national neglected tropical disease program. Communities in intervention arm 2 will receive the same sensitization campaign along with educational audio tools distributed to community households. The control arm will receive no intervention before data collection. Quantitative outcome measures on knowledge and stigma will be collected from a random sample of 1200 individuals. Knowledge will be assessed using the 9-item standardized Knowledge, Attitudes, and Practices Questionnaire. Stigma will be measured using the 7-item Social Distance Scale and the 15-item Explanatory Model Interview Catalogue Community Stigma Scale. We will estimate intention-to-treat effects at the individual level, comparing the outcomes of the intervention and control arms. In an accompanying qualitative component, we will conduct in-depth interviews with community members, community health volunteers, and health care workers in both treatment arms and the control arm to explore intervention and stigma-related experiences. RESULTS: This paper describes and discusses the protocol for a mixed methods cluster randomized controlled trial. Data collection is planned to be completed in June 2024, with ongoing data analysis. The first results are expected to be submitted for publication by the end of 2024. CONCLUSIONS: This trial will be among the first to test the causal effectiveness of community-based sensitization campaigns and audio tools to increase knowledge and reduce leprosy-related stigma. As such, the results will inform health policy makers, decision-makers, and public health practitioners designing sensitization campaigns in rural multilingual settings.

Factors Associated With Precancerous Cervical Lesions in Human Immunodeficiency Virus-Infected Women: A Cross-Sectional Survey in Togo.

Background: The burden of human immunodeficiency virus (HIV) in cervical cancer remains a major public health challenge in developing countries, like Togo. Precancerous lesions include all cellular abnormalities that have malignant potential that can develop into cancer. The objective of this study was to determine the prevalence and factors associated with precancerous cervical lesions in HIV-infected women in our context. Methods: A cross-sectional descriptive study was carried out from November 31, 2022, to January 31, 2023, in an HIV care center in Lomé (Non-Governmental Organization Espoir Vie Togo [NGO EVT] Grand-Lomé-Togo). Results: A total of 271 women were included with a mean age of 47.0 years and a standard deviation of 10.0 years, among whom 20.7% do not have any scholar education. Only 6.7% of them had previously performed cervical smear examinations. The prevalence of precancerous cervical lesions observed in people living with human immunodeficiency virus (PLHIV) was 11.4% with a 95% confidence interval (CI) of 5.0 to 15.4. Cytological abnormalities were marked by low-grade squamous intraepithelial lesion (LSIL) (5.1%), followed by the presence of atypical squamous cells of undetermined significance (ASCUS) (3.5%). A statistically significant association was found between parity and the presence of precancerous lesions (P = .014). Conclusions: In this study, more than 1 out of 10 women living with HIV had precancerous cervical lesions, and parity was the factor associated. The implementation of a systematic screening program for precancerous cervical lesions and human papillomavirus (HPV) infection integrated into HIV care is necessary for early treatment.

Isolation and biocontrol of bacteriophages from wastewater in the city of Lomé, Togo: potential application as a novel source for antimicrobial therapy

Background: Bacteriophages offer one of the most promising solutions to the challenges of antimicrobial resistance in bacteria. The aim of this study is to investigate bacteriophages as a source of new antimicrobial therapy. Methodology: Waste water samples were randomly collected from 8 different locations in the city of Lomé for bacteriophage isolation. The phages were isolated using multi-resistant clinical isolates (Escherichia coli 1642 and Staphylococcus aureus 0868) as hosts by means of a spot test. The host range of the phages was determined also by a spot test using 8 other clinical bacterial isolates including two reference strains (E. coli ATCC 25922 and S. aureus ATCC 29213). The virulence of the phages and their effects on bacterial growth were assessed by in vitro experiments using E. coli 1642 BBec phage suspension. Results: Isolation of phages by the spot test was positive only with the host E. coli 1642. A reduced host range was observed with the other bacteria. The BBec phage suspension showed a titer of 1.6 x 107 PFU/ml. Virulence studies revealed a latency time of less than 10 minutes, a degree of absorption of 87% and a burst size of 63 PFU/cell. The effect of BBec phage suspension on E. coli 1642 showed an almost total reduction in the population of E. coli 1642 after 4 hours. Conclusion: This study provided scientific data showing the antibacterial effect of a phage suspension (BBec) on a multi-resistant clinical isolate of E. coli 1642. This phage could therefore be explored as a candidate for the development of new antibacterial therapies.

[Tetanus, an infectious disease still topical in Lome (Togo)]. / Le tétanos, une maladie infectieuse encore d'actualité à Lomé (Togo).

Introduction: Tetanus still remains a public health problem in Togo despite the existence of the Expanded Program on Immunization. Patients and method: A retrospective and descriptive cohort study was performed from January 1, 2008 to December 31, 2018 in the infectious and tropical diseases department of Sylvanus Olympio teaching hospital of Lome (Togo) on tetanus cases. Results: We included 208 tetanus cases accounting for 6.5% of the whole hospitalizations in the infectious and tropical diseases department at this hospital. The median age of the patients was 23 [13-38 years] with male predominance (81.2%). The patients were workers (63.5%) and came mainly from urban areas (65.9%). Tetanus vaccination was only up to date in 9.3% of patients. Gateways were dominated by skin wounds (66.8%). Antitetanus serum was administered in 191 patients (91.8%) mainly through intrathecal route (189 patients (91.1%)). Complications were marked by superinfection of the wound (n=8), septic shock (n=3), acute respiratory failure and skin necrosis in 1 case respectively. The lethality was 27.4%. Conclusion: The morbidity of tetanus, in particular juvenile morbidity, remains high with significant lethality. It is therefore important to place particular emphasis on the vaccine booster component.

[Oto-rhino-laryngological and cervico-maxillofacial pathologies among hospitalized older patients: epidemiological, diagnostical and therapeutical aspects in Lomé, Togo]. / Pathologies ORL et cervico-maxillo-faciales du sujet âgé en hospitalisation : aspects épidémiologiques, diagnostiques et thérapeutiques à Lomé, Togo.

Introduction: In developing countries, 10% of the population is over 60 years old and this proportion is increasing rapidly. The general objective of this study was to describe the profile and management of the elderly subject aged 60 and over, hospitalized in the ENT (Ear, Nose and Throat) and Head/Neck surgery department of the Sylvanus Olympio University Hospital in Lomé, from 2012 to 2021. Method: Retrospective descriptive study. After reviewing the files, selection of patients aged 60 and over, regardless of sex, and hospitalized for an ENT pathology from January 2012 to December 2021. Not included in our study were files of elderly subjects hospitalized but whose age was imprecise, or empty or very incomplete files. Results: A total of 296 cases were included, representing 6.7% of the department's activities. The mean age of the patients was 72 ± 7.3 years with extremes of 60 and 95 years. The age group 6069 years represented 59.5%. The sex ratio M/F was 0.92. Infectious/inflammatory lesions were found in 138 patients (46.6%) including 38.9% of acute cellulitis of dental origin, and tumors were found in 135 patients (45.6%). Tumors were malignant in 59 patients (43.7%) and benign in 76 patients (56.3%). Thyroid was the site of 46 (60.5%) benign lesions and larynx of 29 (49.2%) malignant lesions. Poor oral hygiene, use of non-steroidal anti-inflammatory drugs, diabetes and the combination of smoking and alcohol were the factors favoring the occurrence of acute cellulitis of dental origin in 89.6%, 80.9%, 20.0% and 2.6% of cases respectively (p<0.001). The combination of smoking and alcohol was a factor favoring the occurrence of malignancy in 39% (p<0.001). Surgical treatment was performed in 234 patients (79.1%). With a case lethality rate of 21%, acute cellulitis of dental origin was the leading cause of death (p<0.001). Conclusion: The most frequent pathologies of the ENT sphere in the elderly in our tropical context were infectious and tumoral, largely dominated by acute cellulitis of dental origin, thyroid adenoma and squamous cell carcinoma of the larynx. Despite the tendency to balance infectious and tumoral pathologies, the proportion of acute cellulitis of dental origin remains twice as high as that of malignant tumors. It contrasts with data from other sub-Saharan series where tumoral pathology remains predominant in the elderly. It is important to provide dental care assistance to the elderly and to advocate for the development of geriatrics and access to universal health coverage for the elderly in Togo.

[PROFILE OF TROPHALLERGEN SENSITIZATION IN CHILDREN IN THE PNEUMO-ALLERGOLOGY DEPARTMENT OF CHU-CAMPUS DE LOMÉ, TOGO]. / Profil de sensibilisation aux trophallergènes chez les enfants dans le service de pneumo-allergologie du CHU-Campus de Lomé, Togo.

Introduction: La sensibilisation aux trophallergènes, bien que mal connue, est décrite comme responsable d'une sensibilité relativement fréquente. L'objectif de cette étude était de décrire le profil de la sensibilisation aux trophallergènes chez les enfants. Méthodes: Il s'est agi d'une étude prospective, descriptive et analytique qui s'est déroulée de 1er juillet 2015 à 30 juin 2022 dans le service de pneumo-allergologie du CHU-Campus de Lomé et ayant porté sur les patients qui après acceptation et réalisation des tests cutanés étaient sensibilisés aux trophallergènes. Résultats: Nous avons recensé au total 468 patients âgés de 7 mois à 18 ans ; la fréquence de réalisation des tests était de 25,9% et celle de la sensibilisation aux trophallergènes de 66,9%. L'âge moyen des patients était de 8,12 ± 0,77 ans. Le sexe ratio était de 1,3. La rhinite allergique était le motif de consultation dans 39,9 % des cas. L'arachide était l'aliment incriminé dans 31,5 % des cas comme trophallergène dans les antécédents personnels. Les patients étaient sensibilisés aux oléagineuses 70,4% (arachide, sésame) ; aux légumineuses 24,6% (soja, haricot) ; aux légumes 4,7% (gombo, corète potagère) ; aux fruits 33,6% (banane, avocat) ; aux céréales 11,8% (blé, maïs) ; aux tubercules 1,9% (manioc, igname) ; à l'œuf 54,9% ; à la crevette 53,6% ; au lait de vache 51,1% ; au crabe 16,5%. Conclusion: La sensibilisation aux trophallergènes était élevée et concernait aussi bien les protéines animales que végétales.

FACTORS OF NON-CONTROL OF ASTHMA IN LOMÉ. / Facteurs de non contrôle de l'asthme à Lomé.

Introduction: L'absence de contrôle de l'asthme fait partie des causes d'exacerbation sévère d'asthme. Les objectifs de ce travail étaient de déterminer la prévalence de l'asthme non contrôlé au centre hospitalier universitaire (CHU) Sylvanus Olympio de Lomé et de décrire les facteurs de non contrôle à Lomé. Méthodes: Il s'est agi d'une étude transversale prospective et descriptive par questionnaire administré à des patients asthmatiques ayant consulté ou ayant été hospitalisés dans le service de Pneumo-Phtisiologie du CHU Sylvanus Olympio de Lomé du 1erjanvier 2019 au 31décembre 2020. Résultats: Nous avons recruté 80 patients. L'âge moyen des patients était de 46,49 +/-19,73 ans avec une prédominance féminine (68%). L'asthme était non ou partiellement contrôlé chez 75% des patients. L'asthme était significativement moins contrôlé chez les patients qui avaient un bas revenu mensuel (p=0,012), qui disposaient à domicile de fauteuils bourrés en tissus (p=0,049), et qui subissaient une pollution de l'air dans leur milieu (p=0,03). Conclusion: Notre étude a révélé que l'asthme non contrôlé est très fréquent au CHU Sylvanus Olympio. Plusieurs facteurs de non contrôle de l'asthme, surtout modifiables, y ont été identifiés. Une sensibilisation de la population, une éducation thérapeutique des patients, et une prise en charge gratuite de l'asthme amélioreront le contrôle de l'asthme et la morbi-mortalité liée à l'asthme.

THE PHARMACIST'S ROLE IN ASTHMA MANAGEMENT IN AFRICA: A SURVEY OF PHARMACISTS IN TOGO. / Rôle du pharmacien dans la prise en charge de l'asthme en Afrique: une enquête auprès des pharmaciens du Togo.

Introduction: La prise en charge de l'asthme nécessite le concours de l'entourage des asthmatiques et de plusieurs partenaires de soins dont les pharmaciens. Les objectifs de l'étude était d'apprécier l'attitude des pharmaciens dans la délivrance des médicaments de l'asthme et d'évaluer leur connaissance sur la technique d'utilisation des aérosols doseurs pressurisés. Méthodes: Il s'est agi d'une enquête transversale réalisée du 5 janvier au 31 mars 2015 par auto- questionnaire auprès de pharmaciens d'officines privées de la ville de Lomé. Toutes les pharmacies privées figurant sur la liste actualisée de la direction générale des pharmacies du Togo étaient retenues. Les pharmaciens non répondeurs après six passages de l'investigateur étaient exclus. L'analyse des données a été faite sur un micro-ordinateur grâce à un logiciel Epi- info version 3.3.2. Résultats: Le taux de participation était de 76,36 %. Tous les pharmaciens ont affirmé recevoir la visite d'un asthmatique à l'officine en période de crise et ou en inter crise. Les asthmatiques se présentaient à l'officine sans aucune prescription médicale. Les médicaments de l'asthme sont délivrés sans exigence d'une ordonnance médicale surtout en période critique. Une prise en charge de la crise d'asthme est assurée par le pharmacien dans 51,20 % des cas à l'officine. L'aérosol doseur était la forme de médicaments la plus proposée. Seulement 27,38 % des pharmaciens ont une maîtrise parfaite de la technique d'utilisation. Les pharmaciens avaient prodigué des conseils aux patients sur la nécessité du traitement de fond, la régularité du suivi médical, l'éviction des allergènes et de la fumée du tabac. Conclusion: Les pharmaciens loin de se limiter seulement à la délivrance des médicaments, doivent s'impliquer dans l'éducation des malades asthmatiques. Mots clés: Asthme-Pharmacien-Education-Togo.
