Poland syndrome: Fortuitous discovery of a familial case in Togo

INTRODUCTION AND IMPORTANCE

Poland syndrome is a rare malformative disease. It is characterized by agenesis or hypoplasia of the pectoralis major muscle associated or not with a malformation of the ipsilateral thoracic limb. The authors report the fortuitous discovery of a familial case of Poland syndrome in Togo.

CASE PRESENTATION

He was a 25-year-old young man, with no known pathological history, examined as part of a physical fitness assessment and who presented with thoracic asymmetry. The clinical and radiological explorations made it possible to conclude to a Poland syndrome in its minor form without any other associated malformation. In addition, three other paternal uncles of the patient presented with the same clinical symptomatology. In the absence of a clear indication, the patient received no treatment.

CLINICAL DISCUSSION

Poland syndrome is a rare congenital malformation. The abnormalities encountered are cutaneous-glandular, osteo-cartilaginous and muscular. The etiopathogenesis of the disease is unknown. The diagnosis is clinical and is based on the demonstration of agenesis of the pectoralis major muscle. The disease does not often lead to functional discomfort; therefore the treatment is not systematic and has only aesthetic value.

CONCLUSION

A rare congenital disease, Poland syndrome can occur sporadically or in families. Its treatment depends above all on the psychological repercussion of the disease.

Sodium, potassium food intake and global cardiovascular risks in Togo

Objectives

To assess urinary sodium/potassium intake and identify its links with global cardiovascular risk (GCVR) according to the WHOPEN approach to WHO/ISH (International High Blood Pressure Society).

Methods

It was a cross-sectional and analytical study that took place from July 6, 2020, to September 17, 2021, in Togo, in the Aneho, Notse and Dapaong localities. It focused on 400 adults selected by sampling. The analysis of two urine samples was done. Cardiovascular risk scores were determined from specific graphs that take into account age, gender, systolic blood pressure, diabetes status, and smoking behavior.

Results

Among the 400 respondents, 49% lived in rural areas. The average age was 41 (30; 51) years. The average sodium and potassium intakes were respectively 3.2 g (1.04-5.99) or 7.95 g of salt and 1.4 g (1.89-5.62) per day. The risk of excessive sodium intake was 2.39 times higher in urban areas than in rural ones (P=0.049). Residing in rural areas was associated with high potassium intakes compared to urban ones [OR=3,2 IC (1.89-5.62)]. Thirteen percent (13%) of respondents were likely to develop at least a deadly or non-deadly cardiovascular disease in the next 10 years 'time, of whom 5% present a high risk. Excessive sodium intake increases by 2.10 times the risk of a deadly cardiovascular disease occurrence.

Conclusions

Sodium intakes are high while potassium intakes are low with a subsequent GCVR in the three cities. Sodium intakes were associated with GCVR. It is necessary to take steps to reduce excessive sodium intake and improve potassium intake.

High SARS-CoV-2 seroprevalence among street adolescents in Lomé, Togo, 2021

BACKGROUND

There is almost no data on the circulation of SARS-CoV-2 among street adolescents. We conducted a study to document the immunization status of street adolescents in Togo against different variants of SARS-CoV-2.

METHODS

A cross-sectional study was carried out in 2021 in Lomé, the city with the highest number of COVID 19 cases in Togo (60%). Adolescents aged 13- and 19 years old living on the street were eligible for inclusion. A standardized questionnaire was administered face-to-face to adolescents. A sample of blood was taken and aliquots of plasma were transported to the virology laboratory of the Hôpital Bichat-Claude Bernard (Paris, France). SARS-CoV-2 anti-S and anti-N IgG were measured using chemiluminescent microparticle immunoassay. A quantitative miniaturized and parallel-arranged ELISA assay was used to detect IgG antibodies specifically directed against the different SARS-CoV-2 Variants of Concern (VOC).

RESULTS

A total of 299 street adolescents (5.2% female), median age 15 years, interquartile range (14-17 years), were included in this study. The prevalence of SARS-CoV-2 infection was 63.5% (95%CI: 57.8-69.0). Specific-IgG against the ancestral Wuhan strain was developed by 92.0% of subjects. The proportion of patients being immunized against each VOC was 86.8%, 51.1%, 56.3%, 60.0, and 30.5% for the Alpha, Beta, Gamma, Delta, and Omicron VOCs, respectively.

CONCLUSION

This study showed a very high prevalence with approximately 2/3 of Togolese street adolescents having antibodies to SARS-CoV-2 due to a previous infection. These results confirm an under-reporting of COVID-19 cases in Togo, questioning the hypothesis of low virus circulation in Togo and even in Africa.

Factors associated with late diagnosis of breast cancer in women in Togo, Sub-Saharan Africa

BACKGROUND

Breast cancer is the most frequently diagnosed cancer in women worldwide. The objective of this study was to identify factors associated with late diagnosis of breast cancer in Togolese women.

METHODS

We conducted a prospective cross-sectional study with descriptive and analytical purposes on cases of breast cancer in women in 2021, in Togo. The patients included in this study were women followed in the gynecology department for stages III and IV breast cancer.

RESULTS

We included 62 cases of breast cancer. The average age of the patients was 38.6 ± 12.5 years with extremes of 17 and 76 years. The breast nodule was the most common reason for consultation in 75.8% of cases. The histological types diagnosed were invasive carcinoma of non-specific type (58; 93.55%), mucinous carcinoma (3; 4.84%) and lobular carcinoma (1; 1.61%). For the stage of the cancer, 43 patients were stage III (69.4%) and 19 stage IV (30.6%). In multivariate analysis, the factors associated with late diagnosis of breast cancer were: fear of diagnosis (aOR = 1.29; p = 0.0014), long delay in diagnosis (aOR = 2.62; p = 0.0001) and failure to perform breast self-examination (aOR = 1.68; p = 0.0022).

CONCLUSION

The fear of the diagnosis, the absence of self-examination of the breasts and the use of traditional treatment and self-medication in first intention constituted the essential factors of the late diagnosis of breast cancer. Strategies should be put in place at the national level to impact on these factors for an early diagnosis of breast cancer.

Lower extremity amputations (LEAs) in a tertiary hospital in Togo: a retrospective analysis of clinical, biological, radiological, and therapeutic aspects

BACKGROUND

We analysed the clinical, biological, radiological profiles, and therapeutic patterns of the patients who underwent a surgical lower extremity amputation (LEA) in Togo from 2010 to 2020.

METHODS

Retrospective analysis of clinical files of adult patients who underwent an LEA at a single centre (Sylvanus Olympio Teaching Hospital) from 1st January 2010 to 31st December 2020. Data were analysed by CDC Epi Info Version 7 and Microsoft Office Excel 2013 software.

RESULTS

We included 245 cases. The mean age was 59.62 years (15.22 SD) (range: 15-90 years). The sex ratio was 1.99. The medical history of diabetes mellitus (DM) was found in 143/222 (64.41%) files. The amputation level found in 241/245 (98.37%) files was the leg in 133/241 (55.19%) patients, the knee in 14/241 (5.81%), the thigh in 83/241 (34.44%), and the foot in 11/241 (4.56%). The 143 patients with DM who underwent LEA had infectious and vascular diseases. Patients with previous LEAs were more likely to have the same limb affected than the contralateral one. The odds of trauma as an indication for LEA were twice as high in patients younger than 65 years compared to the older (OR = 2.095, 95% CI = 1.050-4.183). The mortality rate after LEA was 17/238 (7.14%). There was no significant difference between age, sex, presence or absence of DM, and early postoperative complications (P = 0.77; 0.96; 0.97). The mean duration of hospitalization marked in 241/245 (98.37%) files was 36.30 (1-278) days (36.20 SD). Patients with LEAs due to trauma had a significantly longer hospital admission than those with non-traumatic indications, F (3,237) = 5.505, P = 0.001.

CONCLUSIONS

Compared to previous decades, from 2010 to 2020, the average incidence of LEAs for all causes at Sylvanus Olympio Teaching Hospital (Lomé, Togo) decreased while the percentage of patients with DM who underwent LEAs increased. This setting imposes a multidisciplinary approach and information campaigns to prevent DM, cardiovascular diseases, and  relative complications.

Pharmaco-virological algorithm to target risk of drug resistance among a population of HIV-infected key populations in Togo

No data about antiretroviral (ARV) treatment coverage and virological response are available among key populations (female sex workers [FSW] and Men having Sex with Men [MSM]) in Togo. This study aimed to both describe Human Immunodeficiency Virus (HIV) immunovirological status and evaluate the pertinence of an original algorithm combining pharmacology (PK) and viral load (VL) to identify subjects at risk of ARV drug resistance. A cross-sectional multicentric study was conducted in 2017 in Togo. Our PK-virological algorithm (PK-VA) defines subjects at risk of resistance when exhibiting both detectable plasma drug concentrations and VL > 200 c/mL. Among the 123 FSW and 136 MSM included, 50% and 66% were receiving ARV, with 69% and 80% of them successfully-treated, respectively. Genotypes showed drug-resistance mutation in 58% and 63% of nonvirologically controlled (VL > 200 c/mL) ARV-treated FSW and MSM, respectively. PK-VA would have enabled to save 75% and 72% of genotypic tests, for FSW and MSM, respectively. We reported first data about HIV care cascade among key populations in Togo, highlighting they are tested for HIV but linkage to care remains a concern. Furthermore, 70%-80% of ARV-treated participants experienced virological success. In limited resources settings, where genotyping tests are beyond reach, PK-VA might be an easiest solution to sort out patients needing ARV adaptation due to resistance.

Factors Associated With Esophagus Cancers in Togo, Sub-Saharan Africa

Background

Esophagus cancer is cancer of poor prognosis, of often late diagnosis. The objective of this study was to describe the factors associated with esophagus cancers in the Togolese population.

Methods

It was a retrospective descriptive, cross-sectional study, on esophagus cancers histologically diagnosed at the Pathological Laboratory of Lomé over a period of 31 years (1990-2021).

Results

We have collected 144 cases of esophagus cancer. The average age of patients was 57 ± 12 years, and the sex ratio was 2.34. The most applicant service was the service of Hepato Gastroenterology of CHU Campus (30.6%). Alcohol (57.6%), tobacco (45.8%) were the most present risk factors. Biopsies were the most addressed (97.2%). The average duration of symptom evolution was 6.42 months and the main symptom at the time of diagnosis was dysphagia (36.8%). The location of cancer was the lower third for 71.5% of cases. At histology, epidermoid carcinoma was the dominant type (90.3%). Male sex was statistically associated with the occurrence of epidermoid carcinoma and female sex with the occurrence of adenocarcinoma (P < .001). Alcohol, smoking, and consumption of hot foods were statistically associated with the occurrence of epidermoid carcinoma in this study (P < .05).

Conclusion

Esophagus cancer remains a serious condition for late diagnosis. These are mainly epidermoid carcinomas and having alcohol and tobacco as risk factors. The awareness of the population on the main risk factors would reduce the incidence of oesophagus cancers within the Togolese population.

Effectiveness of seasonal malaria chemoprevention in three regions of Togo: a population-based longitudinal study from 2013 to 2020

BACKGROUND

In 2012, the World Health Organization (WHO) recommended seasonal malaria chemoprevention (SMC) in areas of high seasonal transmission. Though implemented since 2013, the effectiveness of SMC in Togo was never evaluated.

METHODS

This study concerned routine data from 2013 to 2020 mass SMC campaigns for children under five in all health facilities of three Regions of Togo. Treatment coverage, reasons for non-treatment, and SMC-attributable adverse reactions were analysed per year and treatment round. Random effect logistic models estimated SMC effectiveness per health district, year, and treatment round.

RESULTS

The overall coverage was 98% (7,971,877 doses for 8,129,668 children). Contraindication was the main reason for non-administration. Over the study period, confirmed malaria cases decreased from 11,269 (1st round of 2016) to 1395 (4th round of 2020). Only 2,398 adverse reactions were reported (prevalence: 3/10,000), but no severe Lyell syndrome or Stevens-Johnson-type skin reaction. Compared to 2016, malaria prevalence decrease was estimated at 22.6% in 2017 (p < 0.001) and 75% in 2020 (p < 0.001). SMC effectiveness ranged from 76.6% (2nd round) to 96.2% (4th round) comparison with the 1st round.

CONCLUSIONS

SMC reduced significantly malaria cases among children under five. The results reassure all actors and call for effort intensification to reach the WHO goals for 2030.

Prostate cancers in men under the age of 50: about a series in Togo, Sub-Saharan Africa

BACKGROUND

Prostate cancer is a public health problem and increasingly diagnosed in men under 50 years of age. This cancer occurs much more in subjects of advanced age, generally over sixty. The aim of the study was to describe the epidemiological, clinical and histopathological aspects of prostate cancer in men under the age of 50 in Togo.

METHODS

It was a retrospective descriptive, cross-sectional study of histologically confirmed cases of prostate cancer in young adults at the Pathological Laboratory of Lomé over a period of 10 years (2011-2020).

RESULTS

In total, 29 cases of prostate cancer in patients under 50 years of age. The proportion of prostate cancers in men under 50 was 0.7% of all prostate cancers, The average age of the patients was 45 years with extremes of 35 and 49 years. Twelve patients had a family history of prostate cancer, with a statistically significant relationship between the existence of a family history of prostate cancer and the age of onset of the cancer (p-value = 0.03). The dominant clinical information was prostatic hypertrophy (40.37%), followed by acute urine retention (20.69%) and micturition disorders (17.27%). The median Prostate Specific Antigen (PSA) was 188 ng/ml with extremes of 20 ng/ml and 2100 ng/ml. A large proportion of patients had a PSA between 100 and 500 ng/ml. Histologically, they were all prostatic acinar adenocarcinomas. These adenocarcinomas were well differentiated (48%) and moderately differentiated (38%). The predominant histoprognostic grade was ISUP (International Society of Urological Pathology) grade 1 which was noted in 65.52%, followed by grade 2 in 20.69%.

CONCLUSION

Prostate cancer in men under 50 years of age is relatively rare in Togo, sometimes occurring in the context of a family history of prostate cancer. Hence the importance of raising awareness among the male population, especially with a family history of prostate cancer, to start screening early, around the age of 40.

Mandatory health insurance and health care utilization in Togo

BACKGROUND

Despite the implementation of a mandatory health insurance (MHI) scheme in Togo since 2011, its coverage rate remains low, resulting in a high out-of-pocket payment rate. More than 10 years after its implementation, there are few empirical studies investigating the extent to which Togo's mandatory health insurance has improved beneficiaries' access to health care. Examining how MHI and healthcare use in Togo are related is the goal of this study.

METHODS

We use data from the Harmonized Survey on Living Conditions of Households (EHCVM), conducted in the member states of the West African Economic and Monetary Union (WAEMU) in 2018-2019 and covering 6,171 households in Togo. We employ multinomial logistic regression, given that the dependent variable is polytomous.

RESULTS

The results reveal a high rate of non-utilization of healthcare professionals in the case of illness, even among individuals with MHI coverage. Furthermore, the findings show that the MHI increases the likelihood of seeing a specialist physician and other formal health care professionals when sick. The results also reveal that a household's wealth is positively correlated with the likelihood of seeing formal health care professionals. Urban residents are statistically and significantly more likely than rural residents to see both a specialist physician and a general practitioner. The Grand Lomé region has a statistically and significantly higher likelihood of seeing a specialist physician than the Maritime region.

CONCLUSION

The results support the government's plan to implement universal health insurance. The government should take action to raise the standard of treatment provided to insured patients in health care centers. Additionally, the government should consider waiving medical fees for low-income policyholders. When waiving medical costs for low-income policyholders, the Togolese government should focus on the regions with the worst economic conditions. These interventions should be essential to ensure that no one is left behind. The difference between urban and rural communities should be reduced through supply-side policies that focus on rural areas.

Effect of wealth inequality on child and infant mortality in Togo

At birth, individual has a health capital that depends on family, environmental and personal characteristics which depreciates over time requiring investment. It's in this sense that this article aims to analyze the effect of wealth inequality on infant and child mortality in Togo. This effect is accessed by a semi-parametric proportional hazard duration model of Cox. According to the model estimation which is based on data from the Multiple Indicator Cluster Survey (MICS) carried out in Togo in 2017, the results obtained show in one hand that coming from a less wealthy household increases the risk of death for children. On other hand, the results show that the possession of a source of drinking water, the possession of health insurance by the mother, and the mastery of the use of new information technologies and communication reduce the risk of infant and child mortality. In view of these results, policies to reduce wealth inequalities could help reduce the risk of infant and child mortality in proportions ranging from 0.075 to 0.264.

SARS-CoV-2 antibody seroprevalence in Togo: a national cross-sectional household survey, May-June, 2021

BACKGROUND

The extent of SARS-CoV-2 circulation in African countries is still unclear. Seroprevalence studies are a common approach to epidemiological surveillance, allowing estimation of the proportion of people who have had contact with the virus. We aimed at estimating the seroprevalence of anti-SARS-CoV-2 antibodies and associated factors in Togo at the national level in 2021 according to age groups, gender, and place of residence (rural or urban).

METHODS

From 15 May to 31 June 2021, we conducted a nationally representative cross-sectional serological survey in 12 health districts (two districts per health region) in the > 5 years old population in Togo. The Wantai SARS-CoV-2 total antibody assay S protein receptor-binding domain-based ELISA (Wantai Biological Pharmacy Enterprise Co.; Beijing, China) was used to determine the presence of SARS-CoV-2 total antibodies in plasma. Crude and weighted seroprevalences (weighted by age, sex and place of residence) were calculated and then weighted seroprevalences were adjusted according to sensitivity and specificity of the ELISA test. Finally, logistic regression models were performed in order to describe factors associated.

RESULTS

Of the 7593 participants, the overall weighted and adjusted seroprevalence of total anti-SARS-CoV-2 antibodies was 65.5% (CI95%: 18.9-21.1). Urban dwellers, young adults (30-49 years) and vaccinated individuals were significantly more likely to be seropositive.

CONCLUSION

The high seroprevalence we observed is consistent with observations across West Africa. Quantification of the level of immunity in the population is needed to know how close we are to herd immunity. In the meantime, vaccination against the COVID-19 remains necessary.

Children hydrocephalus in Togo: etiologies, treatment, and outcomes

Background

Hydrocephalus is frequent in sub-Saharan African countries. The postinfectious hydrocephalus tends to decrease. The objective of this study was to identify the etiologies and outcomes of hydrocephalus.

Methods

This was a retrospective study of hydrocephalus cases (0-15 years old) treated in the neurosurgery unit of the Sylvanus Olympio Hospital in Lomé over 10 years (2012-2021). At 1 year, the evolution distinguished in two categories: (1) Good psychomotor development: no delay in the acquisition of walking, language, and school. (2) Psychomotor delay: delay in the acquisition of walking, language, and school.

Results

We reported 305 children treated for hydrocephalus representing 1.8% of all neurosurgery unit patients and 34.2% of pediatric pathologies. There was a male predominance (60.6%). We noted second degree consanguinity in 8.5%. The positive maternal serologies were HIV (12.4%), syphilis (8.2%), and toxoplasmosis (2.6%). A malaria episode had been treated during the first trimester in 36.7% of the mothers. The main clinical sign of hydrocephalus was 91.5% of Macrocephalus. Congenital Malformafions were the most common etiologies of hydrocephalus (68.5%). Ventriculoperitoneal shunt was the main surgical method used and 16 deaths were recorded. The medium-term evolution (1 year) was evaluated in 36.1% and noted 61.8% of psychomotor retardation.

Conclusion

This study confirms the trend of the predominance of congenital causes of hydrocephalus in Africa, even if maternal infections can be involved in the development of some of them. The morbimortality of this pathology remains important, especially concerning neurocognitive outcomes.

A case of prune belly syndrome: Experience from a regional hospital in Togo

INTRODUCTION AND IMPORTANCE

Prune Belly syndrome is a rare congenital condition first reported in 1939. It is a malformative disease associated with high mortality. We report a neonatal case in a regional hospital in Togo.

PRESENTATION OF CASE

A 4-month-old male infant was brought to the hospital by his uncle because of a "deformity of the abdomen and absence of testicles". The examination revealed hypoplasia of the abdominal wall associated with bilateral cryptorchidism. Abdominal and urinary tract ultrasound revealed a left pyelocaliceal dilatation and a right megaureter. All these data allowed the diagnosis of Prune Belly syndrome.

CONCLUSION

Prune Belly syndrome is a rare and complex disease with a high mortality rate.

Insecticide resistance intensity and efficacy of synergists with pyrethroids in Anopheles gambiae (Diptera: Culicidae) from Southern Togo

BACKGROUND

This study was designed to provide insecticide resistance data for decision-making in terms of resistance management plans in Togo.

METHODS

The susceptibility status of Anopheles gambiae sensu lato (s.l.) to insecticides used in public health was assessed using the WHO tube test protocol. Pyrethroid resistance intensity bioassays were performed following the CDC bottle test protocol. The activity of detoxification enzymes was tested using the synergists piperonyl butoxide, S.S.S-tributlyphosphorotrithioate and ethacrinic acid. Species-specific identification of An. gambiae s.l. and kdr mutation genotyping were performed using PCR techniques.

RESULTS

Local populations of An. gambiae s.l. showed full susceptibility to pirimiphos methyl at Lomé, Kovié, Anié, and Kpèlè Toutou. At Baguida, mortality was 90%, indicating possible resistance to pirimiphos methyl. Resistance was recorded to DDT, bendiocarb, and propoxur at all sites. A high intensity of pyrethroid resistance was recorded and the detoxification enzymes contributing to resistance were oxidases, esterases, and glutathione-s-transferases based on the synergist tests. Anopheles gambiae sensu stricto (s.s.) and Anopheles coluzzii were the main species identified. High kdr L1014F and low kdr L1014S allele frequencies were detected at all localities.

CONCLUSION

This study suggests the need to reinforce current insecticide-based malaria control interventions (IRS and LLINs) with complementary tools.

Integrated climate change and air pollution mitigation assessment for Togo

Togo, in west Africa, is vulnerable to the impacts of climate change, but has made a negligible contribution to causing it. Togo ratified the Paris Agreement in 2017, committing to submit Nationally Determined Contributions (NDCs) that outline Togo's climate change mitigation commitment. Togo's capital, Lomé, as well as other areas of Togo have ambient air pollutant levels exceeding World Health Organisation guidelines for human health protection, and 91 % of Togolese households cook using solid biomass, elevating household air pollution exposure. In Togo's updated NDC, submitted in 2021, Togo acknowledges the importance and opportunity of achieving international climate change mitigation targets in ways that improve air quality and achieve health benefits for Togo's citizens. The aim of this work is to evaluate priority mitigation measures in an integrated assessment of air pollutant, Short-Lived Climate Pollutant (SLCP) and Greenhouse Gas (GHG) emissions to identify their effectiveness in simultaneously reducing air pollution and Togo's contribution to climate change. The mitigation assessment quantifies emissions for Togo and Grand Lomé from all major source sectors for historical years between 2010 and 2018, for a baseline projection to 2030 and for mitigation scenarios evaluating ten mitigation measures. The assessment estimates that Togo emitted ~21 million tonnes of GHG emissions in 2018, predominantly from the energy and Agriculture, Forestry and Other Land Use sectors. GHG emissions are projected to increase 42 % to 30 million tonnes in 2030 without implementation of mitigation policies and measures. The implementation of the ten identified priority mitigation measures could reduce GHG emissions by ~20 % in 2030 compared to the baseline, while SLCPs and air pollutants were estimated to be reduced more, with a more than 75 % reduction in black carbon emissions in 2030. This work therefore provides a clear pathway by which Togo can reduce its already small contribution to climate change while simultaneously achieving local benefits for air quality and human health in Togo and Grand Lomé.

The patterns and distribution of female genital tuberculosis among Togolese patients

Tuberculosis is a real public health problem in developing countries. The aim of our article was to study the epidemiological, clinical, diagnostic characteristics of female genital tuberculosis in Togo. This was a descriptive and cross-sectional study on all cases concerning histologically diagnosed female genital tuberculosis in the department of pathological anatomy of Lomé in 1997-2018 (20 years). We collected 22 cases of women's Genital tuberculosis (GT), representing 2.2% (1008 cases) of extra-pulmonary tuberculosis. The mean age of the patients was 33.8 ± 0.2 years. Nine (9) patients had a history of treated GT. Depending on the location, the ovaries and fallopian tubes were the most affected (n=9 cases, 40.9%). Eighteen patients (81.8%) had at least one immunosuppression factor including HIV in 13 patients (72.2%). The reasons for consultation were metrorrhagia and pelvic pain with an associated mass in 7 women discovered on clinical examination and imaging. The macroscopic appearance of the specimens was suggestive of the diagnosis of genital tuberculosis in 12 cases (54.5%). Histology revealed caseous necrosis isolated in 3 patients (13.6%) and associated with gigantocellular epithelioid granulomas in 19 patients (86.4%). The patients received standard antibiotic treatment combining rifampicin, isoniazid, ethambutol and pyrazinamide. Genital tuberculosis is a rare extra-pulmonary location in Togo, often occurring in women with HIV, and the clinical polymorphism can lead to confusion with gynecological cancers.

[Trends of HIV and syphilis prevalence among pregnant women in antenatal clinics in Togo: Analysis of sentinel serosurveillance results between 2008 and 2016]

INTRODUCTION

The aim of our work was to analyse the trends of HIV infection and syphilis among pregnant women in prenatal consultation (PNC) in healthcare facilities in Togo.

METHODS

This was an analytical retrospective study, covering the period from 2008 to 2016 and focusing on pregnant women aged 15 to 49 seen in PNC for the first time in maternal and child health services in Togo.

RESULTS

During the study period, 41,536 pregnant women were registered in 2008, 2009, 2010, 2014 and 2016, respectively 8079, 8572, 8430, 7920 and 8535.The mean age of the patients was 26 ± 6 year in 2008, 2009 and 2010. The overall HIV prevalence decreased from 3.4% in 2008 to 2.9% in 2016 (p = 0.0145). It fell from 1% in 2008 to 0.5% in 2016 and from 3.6% in 2008 to 1.4% in 2016 (p < 0.0001) among 15-19 year-old and 20-24 year-old respectively. HIV prevalence in rural areas is two times lower than in urban areas between 2008 and 2016 with a statistically significant difference. The prevalence of syphilis decreased significantly from 2008 (1.3%) to 2016 (0.6%), (p < 0.0001). It is low and not associated with age in 2008; 0.2% and 0.4% in 2016 respectively in the 15 to 19 and 20 to 24 age groups. This prevalence is significantly low between 2008 and 2016 in both urban and rural areas.

CONCLUSION

Our study documents a relatively low prevalence of syphilis and HIV among pregnant women in Togo, with a significant decrease among adolescents and young women, attesting to the effectiveness of the increased screening and comprehensive prevention of sexually transmitted infections (STIs) and HIV, including the antiretroviral treatment as prevention (TASP) approach, and the neonatal syphilis elimination programme in the country.

Prevalence of Malaria and Covid-19 in Febrile Patients in Lomé, Togo in 2020

Purpose

The objective of this study was to estimate the prevalence of malaria and Covid-19 by PCR and serological tests in febrile patients in Lomé.

Methods

A cross-sectional study was conducted from September 1 to October 31, 2020 in febrile patients ≥ 10 years in three health facilities in Lomé. Finger stick blood was collected to detect Plasmodium spp. using thin/thick smear and venous blood on EDTA tubes to test for malaria Histidin-Rich-Protein-2 antigen using rapid diagnostic tests (RDT) and SARS-CoV-2 antibodies specific immunoglobulin (Ig) M and G. Detection of SARS-CoV-2 in nasopharyngeal samples was performed by rRT-PCR using GeneXpert.

Results

A total of 243 participants (61.7% of female) with median age 28 years (IQR 18–41) were included in the study. Prevalence of malaria was 25.1%, 95% CI [19.8–31.0] and 30.4%, 95% CI [24.7–36.7] for thin/thick smear and rapid malaria test, respectively. Eighteen patients (7.4%, 95% CI [4.4–11.5]) were positive for SARS-CoV-2 and forty-two (17.3%, 95% CI [12.8–22.6]) were positive for IgM and/or IgG against SARS-CoV-2. SARS-CoV-2 IgM seroprevalence was significantly higher in malaria RDT positive participants (33.8% vs. 10.1%, p < 0.001).

Conclusion

This study confirms a possible cross-reactivity between Covid-19 and malaria in case of single use of rapid tests, suggesting a possible past contamination. In case of clinical signs related to Covid-19 in malaria-endemic areas, PCR screening should be requested in order to identify and isolate patients.

[Satisfaction of parents of children hospitalized in pediatrics in Togo]

In order to evaluate the degree of satisfaction of parents of children treated in the pediatric service of the Sylvanus-Olympio University Hospital of Lomé (Togo), a cross-sectional and analytical study was conducted from August 1 to 31, 2020, among 300 parents. The sociodemographic aspects of the families and those related to their perception of the care provided in the service were evaluated. Overall, the families were satisfied with the reception and the care their child received.

[Distribution of dermatoses encountered in children seen in Dermatological Consultations in Lomé (Togo)]

OBJECTIVE

The aim of this study was to establish the overview of current dermatosis in children in dermatological consultation in Lomé and to deduce the evolutionary trend of these dermatoses between 1992 and 2020.

METHOD

This was a retrospective descriptive study concerning patients aged 0 to 15 years seen in consultation in the public dermatological services of Lomé from January 1, 2010 to December 31, 2019. The reasons for consultation were reviewed and classified into groups of dermatosis (immunoallergic, infectious, inflammatory, tumoral …). The results of this series were compared with those of a similar study carried out in 1992.

RESULTS

During the study period, 3 767 children attended showing dermatological condition (14.2% of the dermatological consultations were pediatric). The average age of the patients was 7.4 years and the sex ratio M/F was 0.7. July, August and September were the months with the highest number of consultations. The top three reasons for consultation were eczema (26.6%), prurigo strophulus (15.3%) and atopic dermatitis (4.9%). 51.3% of skin diseases in children were represented by immunoallergic dermatoses, followed by infectious dermatoses 23.6%. The predominant infectious dermatoses were fungal (34.4%) and bacterial (30.3%). Between 1992 and 2019, there was an increase in the prevalence of immunoallergic dermatoses and a reduction in infectious dermatoses.

CONCLUSION

Immunoallergic dermatoses are predominant and clearly increasing among children seen in dermatological consultations in Lomé.

Regional heterogeneity of malaria prevalence and associated risk factors among children under five in Togo: evidence from a national malaria indicators survey

BACKGROUND

Malaria remains a major cause of morbidity and death among children less than 5 years of age. In Togo, despite intensification of malaria control interventions, malaria remained highly prevalent, with significant heterogeneity from one region to another. The aim of this study is to explore further such regional differences in malaria prevalence and to determine associated risk factors.

METHODS

Data from a 2017 cross-sectional nationally representative malaria indicator survey was used. Children aged 6-59 months in selected households were tested for malaria using a rapid diagnostic test (RDT), confirmed by microscopy. Univariate and multivariate logistic regression analysis were performed using Generalized Linear Models.

RESULTS

A total of 2131 children aged 6-59 months (1983 in rural areas, 989 in urban areas) were enrolled. Overall 28% of children tested positive for malaria, ranging from 7.0% in the Lomé Commune region to 4% 7.1 in the Plateaux region. In multivariate analysis, statistically significant differences between regions persisted. Independent risk factors identified were higher children aged (aOR = 1.46, 95% CI [1.13-1.88]) for those above 24 months compared to those below; households wealth quintile (aOR = 0.22, 95% CI [0.11-0.41]) for those richest compared to those poorest quintiles; residence in rural areas (aOR = 2.02, 95% CI [1.32-3.13]).

CONCLUSION

Interventions that target use of combined prevention measures should prioritise on older children living in poorest households in rural areas, particularly in the regions of high malaria prevalence.

Breast Primary Angiosarcoma: A Clinicopathologic and Imaging Study of a Series Cases

The aim of our study is to provide clinicopathologic and imaging features of breast primary angiosarcoma. We retrospectively analyzed cases of primary angiosarcoma diagnosed at the Pathological Laboratory of Lomé over a period of 20 years (2000-2019). Eight cases of primary angiosarcoma of the breast were collected, including 6 from women and 2 from men. The median age was 41.63 years (range from 17 to 66 years). Depending on the location, there were 4 of 8 cases in the left breast. Ultrasound classifications were BI-RADS 4 and 5. Histology revealed a malignant vascular proliferation composed of small lumens lined by atypical endothelial cells, evident mitoses, and foci of necrosis. On immunohistochemistry, the lesional cells expressed CD31, CD34, and Factor VIII. Based on Federation Nationale des Centers de Lutte Contre Le Cancer (FNCLCC) grading, the cases were grade II and III. Overall survival at 6 months was estimated to be 25% in a woman.

Assessment of α-Cypermethrin Pour-On Application and Diminazene Aceturate for Treating Trypanosome-Related Diseases Caused by Tsetse Flies on Cattle in Mô, Togo

The effects of tsetse-transmitted trypanosomosis control in high tsetse flies (Glossina spp.) challenge and trypanocidal drug resistance settings remain poorly understood in Togo owing to poor data coverage on the current disease impact. From March 2014 to November 2017, a database of zoo-sanitary surveys integrating the evolution of disease incidence and intervention coverage made it possible to quantify the apparent effects attributable to the control effort, focused on all sedentary cattle breeds in the 1,000 km² area of Mô in Togo. The strategy involved an initial phase with cross-sectional entomological and parasitological. Then, three times a year, 20% of the bovine animals of the study area received α-cypermethrin pour-on, and infected cattle with poor health (798 cattle in 2014 and 358 in 2017) were individually given diminazene aceturate at 7 mg/kg of body weight. The tsetse density in the area decreased significantly, from 1.78 ± 0.37 in March 2014 before the α-cypermethrin application to 0.48 ± 0.07 in February 2017. The α-cypermethrin pour-on application and diminazene aceturate treatment of cattle led to the largest reduction in disease incidence, from 28.1% in 2014 to 7.8% in 2017, an improvement in hematocrit from 24.27 ± 4.9% to 27.5 ± 4.6%, and a reduction in calf mortality from 15.9 ± 11% to 5.9%. Improved access to these interventions for different types of livestock and maintaining their effectiveness, despite high tsetse (Diptera: Glossinidae) challenges, should be the primary focus of control strategies in many areas of Togo.

Neisseria meningitidis Serogroup C Clonal Complex 10217 Outbreak in West Kpendjal Prefecture, Togo 2019

Togo has reported seasonal meningitis outbreaks caused by non-Neisseria meningitidis serogroup A (NmA) pathogens since the introduction of meningococcal serogroup A conjugate vaccine (MACV, MenAfriVac) in 2014. From 2016 to 2017, NmW caused several outbreaks. In early 2019, a NmC outbreak was detected in the Savanes region of Togo and its investigation is described here. Under case-based surveillance, epidemiological and clinical data, and cerebrospinal fluid specimens were collected for every suspected case of meningitis. Specimens were tested for meningitis pathogens using confirmatory microbiological and molecular methods. During epidemic weeks 9 to 15, 199 cases were reported, with 179 specimens being available for testing and 174 specimens (97.2%) were tested by at least one confirmatory method. The NmC was the predominant pathogen confirmed (93.9%), belonging to sequence type (ST)-9367 of clonal complex (CC) 10217. All NmC cases were localized to the West Kpendjal district of the Savanes region with attack rates ranging from 4.1 to 18.8 per 100,000 population and case fatality rates ranging up to 2.2% during weeks 9 to 15. Of the 93 NmC confirmed cases, 63.4% were males and 88.2% were in the 5 to 29 age group. This is the first report of a NmC meningitis outbreak in Togo. The changing epidemiology of bacterial meningitis in the meningitis belt post-MACV highlights the importance of monitoring of emerging strain and country preparedness for outbreaks in the region.

IMPORTANCE The recent emergence of an invasive NmC strain in Togo is an example of the changing bacterial meningitis epidemiology in the meningitis belt post-MACV. The current epidemiology includes the regional circulation of various non-NmA serogroups, which emphasizes the need for effective molecular surveillance, laboratory diagnosis, and a multivalent vaccine that is effective against all serogroups in circulation.
