Trends in Neisseria meningitidis serogroups amongst patients with suspected cerebrospinal meningitis in the meningitis belt of Ghana: a 5-year retrospective study.

BACKGROUND: Serogroup A Neisseria meningitidis was the major cause of meningococcal meningitis epidemics in the African meningitis belt before 2010 when the monovalent meningococcal A conjugate vaccine (MenAfriVac) was introduced in the region. Therefore, this study aimed to establish the trends in N. meningitidis serogroups from 2016 to 2020 in Ghana's meningitis belt. METHODS: Polymerase chain reaction (PCR) confirmed laboratory results of suspected cases of cerebrospinal meningitis from January, 2016 to March, 2020 were obtained from the Tamale Public Health Laboratory. The data were subjected to trend analysis using Statistical Package for the Social Sciences version 25. Differences between discrete variables were analyzed using the Cochran-Armitage trend test. RESULTS: Of the 2,426 suspected cases, 395 (16.3%) were confirmed positive for N. meningitidis using PCR. Serogroup X showed a significant upward trend (P < 0.01), and serogroup W showed a downward trend (P < 0.01). However, no significant trend was observed for any other serogroup. CONCLUSION: This study showed the emergence of serogroup X, a non-vaccine type, as the predominant N. meningitidis serogroup in the wake of a declining serogroup W in Ghana's meningitis belt.

Predictors of vaccination card retention in Tamale Metropolis, Ghana.

BACKGROUND: The home-based vaccination card is an important health record for determining vaccination status of children during surveys, particularly in low- and middle-income countries. However, there are limited evidence on the factors that influence its retention in Ghana. We assessed the predictors of vaccination card retention in Tamale Metropolis, Ghana. METHODS: We conducted a cross-sectional study from 21st December 2022 to 10th January 2023 among children aged 0-59 months in the Tamale Metropolis. Multi-stage sampling was used to select caregivers of children aged 0-59 months for enrolment in the study. Data were collected using validated questionnaire through face-to-face interviews of caregivers. A vaccination card was retained if it was presented for physical inspection by research assistants. The factors that influence vaccination card retention were determined in a multivariate logistic regression analysis at p<0.05. RESULTS: A total of 1,532 eligible children were enrolled in this study. Vaccination card retention was 91.5%. Negative predictors of card retention included: being resident in the Nyohini (AOR = 0.28; 95% CI = 0.15-0.50) and Tamale Central (AOR = 0.51; 95% CI = 0.29-0.90) sub-Metro areas and being caregivers of children aged 24-59 months (AOR = 0.39; 95% CI = 0.22-0.68). On the other hand, paying for the vaccination card (AOR = 5.14; 95% CI = 2.95-8.95) was a positive predictor of vaccination card retention. CONCLUSION: In this study, vaccination card retention among children aged 0-59 months was higher than national estimates. Vaccination card retention was mainly influenced by sub-Metro area, age of child and mode of acquisition of the card such as out-of-pocket payment. There is need to design and deliver tailored messages including the importance of vaccination card retention to caregivers of children based on geographic context. Additionally, the policy on sale of vaccination cards should be revised to allow for cost sharing to enhance its retention.

Predictive signs and symptoms of bacterial meningitis isolates in Northern Ghana.

Cerebrospinal meningitis (CSM) is a public health burden in Ghana that causes up to 10% mortality in confirmed cases annually. About 20% of those who survive the infection suffer permanent sequelae. The study sought to understand the predictive signs and symptoms of bacterial meningitis implicated in its outcomes. Retrospective data from the Public Health Division, Ghana Health Service on bacterial meningitis from 2015 to 2019 was used for this study. A pre-tested data extraction form was used to collect patients' information from case-based forms kept at the Disease Control Unit from 2015 to 2019. Data were transcribed from the case-based forms into a pre-designed Microsoft Excel template. The data was cleaned and imported into SPSS version 26 for analysis. Between 2015 and 2019, a total of 2446 suspected bacterial meningitis cases were included in the study. Out of these, 842 (34.4%) were confirmed. Among the confirmed cases, males constituted majority with 55.3% of the cases. Children below 14 years of age were most affected (51.4%). The pathogens commonly responsible for bacterial meningitis were Neisseria meningitidis (43.7%) and Streptococcus pneumoniae (53.0%) with their respective strains Nm W135 (36.7%), Nm X (5.1%), Spn St. 1 (26.2%), and Spn St. 12F/12A/12B/44/4 (5.3%) accounting for more than 70.0% of the confirmed cases. The presence of neck stiffness (AOR = 1.244; C.I 1.026-1.508), convulsion (AOR = 1.338; C.I 1.083-1.652), altered consciousness (AOR = 1.516; C.I 1.225-1.876), and abdominal pains (AOR = 1.404; C.I 1.011-1.949) or any of these signs and symptoms poses a higher risk for testing positive for bacterial meningitis adjusting for age. Patients presenting one and/or more of these signs and symptoms (neck stiffness, convulsion, altered consciousness, and abdominal pain) have a higher risk of testing positive for bacterial meningitis after statistically adjusting for age.

Attempted suicide of two confirmed SARS-CoV-2 infected patients in an isolation facility and recommendations to prevent COVID-19 suicides: a case report.

COVID-19 pandemic has disrupted our way of life and continue to exert significant psychological impact. A surge in suicide has been associated with all previous major epidemics and pandemics. The suicide rate associated with COVID-19 pandemic would continue increasing if urgent measures are not put in place. We report two cases of attempted suicide among confirmed COVID-19 patients. The first case is a 30-year-old nurse who attempted suicide in an isolation facility and the second case is a 43-year-old male who travelled with his wife and a trusted friend from Burkina-Faso to Ghana to access haemodialysis care for his wife in a COVID-19 pandemic era. Unfortunately, the couple tested positive for SARS-CoV-2 infection. We discussed interventions to prevent suicide in treatment facilities. We recommend psychological assessment and counselling for all COVID-19 patients. We also recommend social interaction among patients in the isolation or treatment centres, and active management of COVID-19 related stigma and misinformation. Screening for means of suicide should be conducted in treatment facilities. Pre-test and post-test counselling are essential interventions. Also, telemedicine, telephone calls, computer assisted psychotherapy, mobile applications, self-guided digital interventions have been identified as effective tools for administering psychotherapeutic interventions to COVID-19 patients particularly in instances where face-to-face may not be possible.

Performance of COVID-19 associated symptoms and temperature checking as a screening tool for SARS-CoV-2 infection.

INTRODUCTION: Coronavirus disease-19 (COVID-19), which started in late December, 2019, has spread to affect 216 countries and territories around the world. Globally, the number of cases of SARS-CoV-2 infection has been growing exponentially. There is pressure on countries to flatten the curves and break transmission. Most countries are practicing partial or total lockdown, vaccination, massive education on hygiene, social distancing, isolation of cases, quarantine of exposed and various screening approaches such as temperature and symptom-based screening to break the transmission. Some studies outside Africa have found the screening for fever using non-contact thermometers to lack good sensitivity for detecting SARS-CoV-2 infection. The aim of this study was to determine the usefulness of clinical symptoms in accurately predicting a final diagnosis of COVID-19 disease in the Ghanaian setting. METHOD: The study analysed screening and test data of COVID-19 suspected, probable and contacts for the months of March to August 2020. A total of 1,986 participants presenting to Tamale Teaching hospital were included in the study. Logistic regression and receiver operator characteristics (ROC) analysis were carried out. RESULTS: Overall SARS-CoV-2 positivity rate was 16.8%. Those with symptoms had significantly higher positivity rate (21.6%) compared with asymptomatic (17.0%) [chi-squared 15.5, p-value, <0.001]. Patients that were positive for SARS-CoV-2 were 5.9 [3.9-8.8] times more likely to have loss of sense of smell and 5.9 [3.8-9.3] times more likely to having loss of sense of taste. Using history of fever as a screening tool correctly picked up only 14.8% of all true positives of SARS-CoV-2 infection and failed to pick up 86.2% of positive cases. Using cough alone would detect 22.4% and miss 87.6%. Non-contact thermometer used alone, as a screening tool for COVID-19 at a cut-off of 37.8 would only pick 4.8% of positive SARS-CoV-2 infected patients. CONCLUSION: The use of fever alone or other symptoms individually [or in combination] as a screening tool for SARS-CoV-2 infection is not worthwhile based on ROC analysis. Use of temperature check as a COVID-19 screening tool to allow people into public space irrespective of the temperature cut-off is of little benefit in diagnosing infected persons. We recommend the use of facemask, hand hygiene, social distancing as effective means of preventing infection.

Cardiometabolic Risk Factors and Preclinical Target Organ Damage Among Adults in Ghana: Findings From a National Study.

Background Although sub-Saharan Africa has a high prevalence of cardiovascular diseases (CVDs), there remains a lack of systematic and comprehensive assessment of risk factors and early CVD outcomes in adults in sub-Saharan Africa. Methods and Results Using a stratified multistage random sampling method, we recruited 1106 men and women, aged >18 years, from the general population in Ghana to participate in a national health survey from 2016 to 2017. In Ghanaian adults, the age-standardized prevalence of known CVD risk factors was 15.1% (95% CI, 12.9%-17.3%) for obesity, 6.8% (95% CI, 5.1%-8.5%) for diabetes mellitus, 26.1% (95% CI, 22.9%-29.4%) for hypertension, and 9.3% (95% CI, 7.1%-11.5%) for hyperuricemia. In addition, 10.1% (95% CI, 7.0%-13.2%) of adults had peripheral artery disease, 8.3% (95% CI, 6.7%-10.0%) had carotid thickening, 4.1% (95% CI, 2.9%-5.2%) had left ventricular hypertrophy, and 2.5% (95% CI, 1.5%-3.4%) had chronic kidney disease. Three CVD risk factors appeared to play prominent roles in the development of target organ damage, including obesity for peripheral artery disease (odds ratio [OR], 2.22; 95% CI, 1.35-3.63), hypertension for carotid thickening (OR, 1.92; 95% CI, 1.22-3.08), and left ventricular hypertrophy (OR, 5.28; 95% CI, 2.55-12.11) and hyperuricemia for chronic kidney disease (OR, 5.49; 95% CI, 2.84-10.65). Conclusions This comprehensive health survey characterized the baseline conditions of a national cohort of adults while confirming the prevalence of CVD risk factors, and early CVD outcomes have reached epidemic proportions in Ghana. The distinct patterns of risk factors in the development of target organ damage present important challenges and opportunities for interventions to improve cardiometabolic health among adults in Ghana.

Diagnosis of bacterial meningitis in Ghana: Polymerase chain reaction versus latex agglutination methods.

Bacterial meningitis is a public health crisis in the northern part of Ghana, where it contributes to very high mortality and morbidity rates. Early detection of the causative organism will lead to better management and effective treatment. Our aim was to evaluate the diagnostic accuracy of Pastorex and Wellcogen latex agglutination tests for the detection of bacterial meningitis in a resource-limited setting. CSF samples from 330 suspected meningitis patients within the northern zone of Ghana were analysed for bacterial agents at the zonal Public Health Reference Laboratory in Tamale using polymerase chain reaction (PCR) and two latex agglutination test kits; Pastorex and Wellcogen. The overall positivity rate of samples tested for bacterial meningitis was 46.4%. Streptococcus pneumoniae was the most common cause of bacterial meningitis within the sub-region, with positivity rate of 25.2%, 28.2% and 28.8% when diagnosed using Wellcogen, Pastorex and PCR respectively. The Pastorex method was 97.4% sensitive while the Wellcogen technique was 87.6% sensitive. Both techniques however produced the same specificity of 99.4%. Our study revealed that the Pastorex method has a better diagnostic value for bacterial meningitis than the Wellcogen method and should be the method of choice in the absence of PCR.

Continued occurrence of serotype 1 pneumococcal meningitis in two regions located in the meningitis belt in Ghana five years after introduction of 13-valent pneumococcal conjugate vaccine.

BACKGROUND: Increases in pneumococcal meningitis were reported from Ghanaian regions that lie in the meningitis belt in 2016-2017, despite introduction of 13-valent pneumococcal conjugate vaccine (PCV13) in 2012 using a 3-dose schedule (6, 10, and 14 weeks). We describe pneumococcal meningitis epidemiology in the Ghanaian Northern and Upper West regions across two meningitis seasons. METHODS: Suspected meningitis cases were identified using World Health Organization standard definitions. Pneumococcal meningitis was confirmed if pneumococcus was the sole pathogen detected by polymerase chain reaction, culture, or latex agglutination in cerebrospinal fluid collected from a person with suspected meningitis during December 2015-March 2017. Pneumococcal serotyping was done using PCR. Annual age-specific pneumococcal meningitis incidence (cases per 100,000 population) was calculated, adjusting for suspected meningitis cases lacking confirmatory testing. FINDINGS: Among 153 pneumococcal meningitis cases, 137 (89.5%) were serotyped; 100 (73.0%) were PCV13-type, including 85 (62.0%) that were serotype 1, a PCV13-targeted serotype. Persons aged ≥5 years accounted for 96.7% (148/153) of cases. Comparing 2015-2016 and 2016-2017 seasons, the proportion of non-serotype 1 PCV13-type cases decreased from 20.0% (9/45) to 4.1% (3/74) (p = 0.008), whereas the proportion that was serotype 1 was stable (71.1% (32/45) vs. 58.1% (43/74); p = 0.16). Estimated adjusted pneumococcal meningitis incidence was 1.8 in children aged <5 years and ranged from 6.8-10.5 in older children and adults. CONCLUSIONS: High pneumococcal meningitis incidence with a large proportion of serotype 1 disease in older children and adults suggests infant PCV13 vaccination has not induced herd protection with this schedule in this high-transmission setting.

Assessment of the environmental risk factors for a gastric ulcer in northern Ghana.

Numerous risk factors have been implicated in the development of a gastric ulcer. Common risk factors are Helicobacter pylori infection, chronic non-steroidal anti-inflammatory intake, and alcohol consumption. The aim of the current study was to identify environmental risk factors for a gastric ulcer in northern Ghana. The data for this retrospective study were obtained from 2035 patient records from the Minimal Access Therapy and Operative Endoscopy unit of the Tamale Teaching Hospital in Tamale, Ghana from 2010 to 2014. A separate questionnaire was administered to assess the environmental risk factors. The rapid urease test was used to determine the presence of H. pylori. The Statistical Package for Social Sciences version 20.0 was used to analyse the data. Univariate and bivariate analyses were performed, and the results were presented in tables provided. The Chi-square values of the bivariate analysis were considered statistically significant when P < 0.05. Bivariate analysis revealed a strong association between gastric ulcer and various risk factors such as smoking (P = 0.001, χ2 = 27.3), fasting (P = 0.001, χ2 = 42.6), H. pylori infection (P = 0.01, χ2 = 19.9), and alcohol consumption (P = 0.001, χ2 = 30.6). There was no association between the traditional herbal preparation usage (P = 0.251, χ2 = 1.8) and the gastric ulcer. Environmental risk factors responsible for the development of a gastric ulcer in people of the northern part of Ghana show a similar pattern to other geographical regions of the world.
