RESUMO

Industrialization has impacted the human gut ecosystem, resulting in altered microbiome composition and diversity. Whether bacterial genomes may also adapt to the industrialization of their host populations remains largely unexplored. Here, we investigate the extent to which the rates and targets of horizontal gene transfer (HGT) vary across thousands of bacterial strains from 15 human populations spanning a range of industrialization. We show that HGTs have accumulated in the microbiome over recent host generations and that HGT occurs at high frequency within individuals. Comparison across human populations reveals that industrialized lifestyles are associated with higher HGT rates and that the functions of HGTs are related to the level of host industrialization. Our results suggest that gut bacteria continuously acquire new functionality based on host lifestyle and that high rates of HGT may be a recent development in human history linked to industrialization.

RESUMO

BACKGROUND AND AIMS: Data are needed to inform hepatitis B virus (HBV) testing and treatment policies in Ghana to make progress towards achieving the 2030 WHO elimination targets. This study investigated testing patterns for HBV and described the age, sex, and region-specific prevalence of HBV infection in Ghana using hospital data. METHODS: A nationwide multi-centre cross-sectional study was performed where hospital-based registers were reviewed. These included review of 139,966 laboratory, 169,048 blood bank, and 83,920 delivery register entries from 22 healthcare institutions in Ghana. Frequencies and proportions, and crude and pooled estimates reported. Chi squared test was used for tests of independence. Logistic regression was used to identify factors associated with a positive test result. RESULTS: The crude HBsAg seroprevalence was 8.48% (95%CI 8.25-8.57%) with pooled estimate of 11.40% (95%CI 10.44-12.35). HBsAg seroprevalence among children under 5 years was 1.87% (95%CI 1.07-3.27) and highest age-specific seroprevalence was in those 40-49 years. The highest region-specific seroprevalences was in the Savannah (22.7%). Predictors of a positive HBsAg RDT test included female sex (OR 0.81 95% CI 0.74-0.88), and age (OR 1.005 95%CI 1.002-1.007). The proportion of parturient women receiving HBsAg testing increased between 2017 (87.2%) and 2020 (94.3%) (p < 0.001). The crude HBsAg seroprevalence in parturient women was 6.14% (95% CI 5.97-6.31). Among blood donors the crude HBsAg seroprevalence was 5.69% (95%CI 5.58-5.80). Data from 2 teaching hospitals indicated that in 2020, although 1500 HBsAg positive tests were recorded only 746 serological profile and 804 HBV DNA tests were performed. HBV e antigen seroprevalence was 6.28% (95%CI 4.73-7.84). CONCLUSION AND RECOMMENDATIONS: Ghana remains a country with high HBV burden. There is an unequal distribution, with higher HBsAg seroprevalence in the north of the country. Furthermore, PCR testing is not widely available outside of large teaching hospitals, which limits diagnostic work-up. Hepatitis reporting systems and registers should be improved to facilitate data capture of indicators and standardised across the country to allow for comparability. Furthermore, where gains have been made in testing among pregnant women, there is a need for linkage to appropriate care.

RESUMO

BACKGROUND: End-stage liver disease (ESLD) is a major burden on public health, particularly in sub-Saharan Africa, where hepatitis B virus (HBV) is an important risk factor. We aimed to describe clinical characteristics of ESLD from cirrhosis or hepatocellular carcinoma (HCC) and the performance of aspartate aminotransferase (AST)-platelet ratio index (APRI) and alpha fetoprotein (AFP) in Ghana. METHODS: We performed an observational cross-sectional study in outpatient hepatology clinics at three teaching hospitals in Ghana, West Africa. One hundred and forty-one HCC, 216 cirrhosis and 218 chronic HBV patients were recruited by convenience sampling. Sociodemographic, history and examination, laboratory, and disease staging information were shown using descriptive statistics. Performance of the APRI score in diagnosis of cirrhosis and AFP in the diagnosis of HCC was determined using AUROC analysis. RESULTS: Median age at presentation was 44 years for HCC and 46 years for cirrhosis. HBV was found in 69.5% of HCC and 47.2% of cirrhosis cases, and HCV in 6.4% and 3.7% respectively. APRI cut-off of 2 had sensitivity of 45.4% and specificity of 95% in diagnosis of cirrhosis, and cut-off of 1 had sensitivity of 75.9% and specificity of 89%. AUC of AFP was 0.88 (95% CI 0.81-0.94) in diagnosis of HCC. Low monthly income was associated with lower odds of undertaking AFP. Thirty one percent of cirrhotic persons were Child-Pugh C, and 67.9% of HCC patients had advanced or terminal disease at presentation. CONCLUSIONS: Our findings emphasize the young age of ESLD patients in Ghana and the advanced nature at presentation. It highlights shortcomings in surveillance and the need for policies to address the burden and improve outcomes in Ghana.

RESUMO

BACKGROUND: Kidney diseases have emerged as significant cause of morbidity and mortality in HIV subject on antiretroviral therapy (ART). In Ghana, routine follow up of HIV positive clients is by estimation of serum creatinine and urea levels. Glomerular Filtration Rate (GFR) is not routinely calculated and proteinuria is not routinely checked. This study sought to investigate the kidney profiles of adult HIV/AIDS patients being managed on ART at the Cape Coast Teaching Hospital (CCTH), Ghana. METHODS: A hospital-based analytical cross sectional study with a retrospective component was conducted using systematic sampling method to recruit HIV/AIDS who visited the ART clinic. A total of 440 participants of both sexes aged 18 years and above, confirmed as HIV/AIDS positive and on ART were involved in this study. Blood and urine samples were collected from all subjects and the levels of serum creatinine and urea and proteinuria were estimated and eGFR calculated using the Modification of Diet in Renal Disease (MDRD) equations. Data analyses were performed using Stata version 13 software (Stata Corp, Texas USA). RESULTS: The mean age (years) of participants was 45.5 years (±11.6) with 288 (65.4%) being on Tenofovir based ART regimen. The mean eGFR was found to decrease from 112.4 ml/min/1.73 m at baseline, to 103.4 ml/min/1.73 m after 6 months on ART and to a mean of 99.4 ml/min/1.73 m at recruitment into this study. Factors which were found to be associated with having eGFR < 60 included age, gender and CD4 count though not statistically significant. Patients > 45 years had the highest odds with OR 2.0 (95% CI: 0.8-5.1), females had higher odds with OR 1.5 (95% CI: 0.5-5.2), and those with CD4 count > 350 had OR of 0.4 (95% CI 0.2-1.3). A total of 30.9% of the participants had proteinuria at recruitment. TDF based ART regimen had no statistically significant effect on serum creatinine and urea levels. CONCLUSION: Estimated GFR decreased after 6 months among patients on ART despite normal serum creatinine and urea levels. This finding suggests that clients in care at HIV/ART clinics in Ghana may benefit from routine estimation of GFR and proteinuria.

RESUMO

BACKGROUND: Helicobacter pylori infection affects more than half of the world's population. It is generally acquired during childhood with no symptoms but has long- term clinical sequelae. This study estimated the prevalence of H. pylori infection amongst children in a rural environment in Africa. METHODS: We conducted a cross-sectional study over a four (4)-month period within two rural communities. 240 asymptomatic children were tested using lateral flow immunochromatographic assay for the qualitative detection of H. pylori antigen in a fecal specimen. Statistical analysis and processing was done using Stata version 11. RESULTS: The mean age of the participants was 10.5 ± 2.7 years with the predominant age range being 8-10 years (34.6%), and a mean household size of 7.1 ± 1.7. The study population showed a female preponderance of 57.1%. 88% of the H. pylori positive children lacked pipe and borehole drinking water. All of the positive H. pylori children practiced open-air defecation. The overall prevalence of H. pylori infection among children in this study was at least 14.2%. CONCLUSION: Our study demonstrated a high prevalence of H. pylori infection among children in a rural setting. Educational status of parents did not affect H. pylori prevalence but increasing household numbers, female gender, source of drinking water other than pipe and borehole, open-air defecation and younger age were associated with a higher H. pylori prevalence.

RESUMO

Cirrhosis represents the end stage of chronic liver disease. Sub-Saharan Africa, a resource-constrained region, has a high burden of chronic liver disease, with causes including chronic viral hepatitis, excessive alcohol use, and metabolic dysfunction-associated steatotic liver disease (MASLD), the risk of which is burgeoning. The development of liver cirrhosis predicts for morbidity and mortality, driven by both liver dysfunction and the consequences of portal hypertension. Compensated cirrhosis portends a better prognosis than decompensated cirrhosis, highlighting the need for the early diagnosis of cirrhosis and its causes. With resource challenges, the diagnosis and management of cirrhosis is demanding, but less costly and less invasive interventions with substantial benefits, ranging from simple blood tests to transient elastography, are feasible in such settings. Simple interventions are also available to manage the complex manifestations of decompensation, such as ß blockers in variceal bleeding prophylaxis, salt restriction and appropriate diuretic use in ascites, and lactulose and generic rifaximin in hepatic encephalopathy. Ultimately, managing the underlying causative factors of liver disease is key in improving prognosis. Management demands expanded policy interventions to increase screening and treatment for hepatitis B and C and reduce alcohol use and the metabolic factors driving MASLD. Furthermore, the skills needed for more specialised interventions, such as transjugular intrahepatic portosystemic shunt procedures and even liver transplantation, warrant planning, increased capacity, and support for regional centres of excellence. Such centres are already being developed in sub-Saharan Africa, demonstrating what can be achieved with dedicated initiatives and individuals.

RESUMO

The current burden of Hepatitis C virus infection and the availability of HCV-related services in Ghana are not well described. Previous estimates on HCV seroprevalence in the country are outdated. This study investigated the HCV seroprevalence and testing and treatment capacity in Ghana. A multi-centre cross-sectional study was conducted in which laboratory and blood bank registers from 17 public healthcare institutions in Ghana were reviewed. A survey on cost and availability of HCV-related testing and treatment was also performed. Crude and pooled estimates of HCV seroprevalence, frequency and median cost of available diagnostic tests and medicines were described. The crude HCV seroprevalence was 2.62% (95% CI 2.53-2.72) and the pooled estimate was 4.58% (95% CI 4.06-5.11) among 103,609 persons tested in laboratories. Age (OR 1.02 95% CI 1.01-1.02) and male sex (OR 1.26 95% CI 1.08-1.48) were predictors of a positive anti-HCV RDT test. Northern administrative regions in Ghana had the highest HCV seroprevalence ranging from 8.3-14.4%. Among 55, 458 potential blood donors, crude HCV seroprevalence was 3.57% (95% CI 3.42-3.72). Testing was through Rapid Diagnostic Test (RDT) kits in most facilities, and only 2 of 17 centres were performing HCV RNA testing. The median cost of an anti-HCV RDT test was $0.97 (0-1.61) and $3.23 (1.61-7.58) for persons with and without government health insurance respectively. The median cost of a 12-week course of the pan-genotypic direct-acting antiviral therapy sofosbuvir-daclatasvir was $887.70. In conclusion, there are significant regional differences in HCV burden across Ghana. Limited access to and cost of HCV RNA and DAA therapy hinders testing and treatment capability, and consequently HCV elimination efforts. A national HCV program supported with a sustainable financing plan is required to accelerate HCV elimination in Ghana.

RESUMO

BACKGROUND: Sub-Saharan Africa faces a rapid spread of diabetes mellitus type 2 (DM2) but its potentially specific characteristics are inadequately defined. In this hospital-based study in Kumasi, Ghana, we aimed at characterizing clinical, anthropometric, socio-economic, nutritional and behavioural parameters of DM2 patients and at identifying associated factors. METHODS: Between August 2007 and June 2008, 1466 individuals were recruited from diabetes and hypertension clinics, outpatients, community, and hospital staff. Fasting plasma glucose (FPG), serum lipids and urinary albumin were measured. Physical examination, anthropometry, and interviews on medical history, socio-economic status (SES), physical activity and nutritional behaviour were performed. RESULTS: The majority of the 675 DM2 patients (mean FPG, 8.31 mmol/L) was female (75%) and aged 40-60 years (mean, 55 years). DM2 was known in 97% of patients, almost all were on medication. Many had hypertension (63%) and microalbuminuria (43%); diabetic complications occurred in 20%. Overweight (body mass index > 25 kg/m2), increased body fat (> 20% (male), > 33% (female)), and central adiposity (waist-to-hip ratio > 0.90 (male), > 0.85 (female)) were frequent occurring in 53%, 56%, and 75%, respectively. Triglycerides were increased (≥ 1.695 mmol/L) in 31% and cholesterol (≥ 5.17 mmol/L) in 65%. Illiteracy (46%) was high and SES indicators generally low. Factors independently associated with DM2 included a diabetes family history (adjusted odds ratio (aOR), 3.8; 95% confidence interval (95%CI), 2.6-5.5), abdominal adiposity (aOR, 2.6; 95%CI, 1.8-3.9), increased triglycerides (aOR, 1.8; 95%CI, 1.1-3.0), and also several indicators of low SES. CONCLUSIONS: In this study from urban Ghana, DM2 affects predominantly obese patients of rather low socio-economic status and frequently is accompanied by hypertension and hyperlipidaemia. Prevention and management need to account for a specific risk profile in this population.

RESUMO

BACKGROUND: Heart disease remains a leading cause of morbidity and mortality, particularly in low- and middle-income countries. Access to diagnostic modalities is limited in these settings. Limited echocardiographic studies performed by non-cardiologists can increase access, improve diagnosis and allow for earlier medical therapy. METHODS: Two internal medicine residents at a tertiary-level hospital in Ghana were trained to perform limited echocardiographic studies. Each trainee performed 50 echocardiograms and interpreted 20 studies across three predetermined timepoints. Interpretation was compared to expert interpretation. RESULTS: Agreement improved over time. At the final evaluation, there was high agreement across all aspects: left ventricular structure (70%, kappa 0.52, p = 0.01), left ventricular function (80%, kappa 0.65, p = 0.004), right ventricular structure (90%, kappa 0.71, p = 0.002), right ventricular function (100%, kappa 1.00, p < 0.001), and presence of effusion (100%, kappa 1.00, p < 0.001). CONCLUSIONS: Non-cardiologists can be trained in focused echocardiography using handheld machines. Such training can increase access to diagnostic capabilities in resource-limited settings.

RESUMO

Inflammatory bowel disease (IBD) is generally considered a disease of high-income countries and is regarded as rare in sub-Saharan Africa. However, this assumption is almost certainly an underestimate, and the high burden of communicable diseases makes IBD in sub-Saharan Africa difficult to detect. Furthermore, some gastrointestinal infections can closely mimic IBD, contributing to delays in diagnosis and complicating therapeutic decision making. Constraints in endoscopic capacity alongside a scarcity of qualified diagnostic pathologists add to the difficulties. Implementing evidence-based guidelines recommended by international societies is challenging, mostly due to high costs and unavailability of medication. However, cost-effective approaches can still be implemented to manage IBD in sub-Saharan Africa as the predominant disease phenotype is mild-to-moderate ulcerative colitis, which often responds to treatment with basic medication. In this Series paper, we summarise the current management of IBD in sub-Saharan Africa and propose how it can be tailored to suit the epidemiological and socioeconomic specificities of the region. We also discuss measures required to address existing challenges, such as educating health-care workers about the diagnosis and management of IBD or improving endoscopic capacity.

RESUMO

Liver-related diseases, including liver cirrhosis and hepatocellular carcinoma (HCC), are significant causes of mortality globally. Specific causes and predictors of liver-related mortality in low resource settings require assessment to help inform clinical decision making and develop strategies for improved survival. The objectives of this study were to determine the proportion of liver-related deaths associated with liver cirrhosis, HCC, and their known risk factors, and secondly to determine predictors of in-hospital mortality among cirrhosis and HCC patients in Ghana. We first performed a cross-sectional review of death register entries from 11 referral hospitals in Ghana to determine the proportion of liver-related deaths and the proportion of risk factors associated with these deaths. Secondly, we conducted a retrospective cohort review of 172 in-patient liver cirrhosis and HCC cases admitted to a tertiary referral centre and determined predictors of in-hospital mortality using binary logistic regression and Kaplan-Meier survival analysis. In total, 8.8% of deaths in Ghanaian adults were due to liver-related causes. The proportion of liver-related deaths attributed to HBV infection was 48.8% (95% CI: 45.95-51.76), HCV infection was 7.0% (95% CI: 5.58-8.45), HBV-HCV co-infection 0.5% (95% CI: 0.1-0.9) and alcohol was 10.0% (95% CI: 8.30-11.67). Of 172 cases of HCC and liver cirrhosis, the in-patient mortality rate was 54.1%. Predictors of in-patient mortality in cirrhotic patients were increasing WBC (OR = 1.14 95% CI: 1.00-1.30) and the revised model for end-stage liver disease with sodium (MELD-Na) score (OR = 1.24 95% CI: 1.01-1.54). For HCC patients, female sex (OR = 3.74 95% CI: 1.09-12.81) and hepatic encephalopathy (grade 1) were associated with higher mortality (OR = 5.66 95% CI: 1.10-29.2). In conclusion, HBV is linked to a high proportion of HCC-related deaths in Ghana, with high in-hospital mortality rates that require targeted policies to improve survival.

RESUMO

BACKGROUND: Type 2 diabetes mellitus (T2DM) patients are likely to develop kidney disease. The need to identify more accessible and cheaper diagnostic biomarkers cannot be overemphasized. This study investigated the ability of serum uric and uric acid to creatinine ratio in assessing the kidney function of T2DM patients and determined the relationship between serum uric acid to creatinine ratio and estimated glomerular filtration rate (eGFR). METHODS: One hundred and fifty-five (155) consented T2DM patients were recruited from the diabetes clinic of the Cape Coast Teaching hospital. Anthropometric variables and blood pressure were measured. Serum uric acid (SUA), serum creatinine and urine protein were estimated using standard protocols. Uric acid to creatinine ratio (UA:CR), eGFR were then calculated. RESULTS: From the receiver operator characteristic (ROC) curve obtained, serum uric acid was found to be a better predictor of impaired renal function than UA:CR at p = 0.0001. The uric acid levels of participants in the fourth quartile of each category was found to be significant at p = 0.010 and can be used as indicators of kidney function in these participants. According to the odds ratio, the UA:CR will not be suitable to be used as an indicator of kidney function in any of the participants because their odds ratios were all less than 1. A total of 29(18.7 %) participants were found to have CKD with their eGFR falling below 60 ml/mins per 1.73 m2. A significant positive relationship was found between serum uric acid and the staging of CKD according to eGFR whiles a negative relationship was found with UA:CR and CKD (p < 0.0001). CONCLUSIONS: Serum uric acid is a better indicator of renal impairment (eGFR < 60 ml/mins per 1.73 m2) than UA:CR in patients with type 2 diabetes mellitus.

RESUMO

BACKGROUND: Acute kidney injury (AKI) is a syndrome associated with high morbidity, mortality and high hospital costs. Despite its adverse clinical and economic effects, only a few studies have reported reliable estimates on the incidence of AKI in sub-Sahara Africa. We assessed the incidence and associated factors of AKI among medical and surgical patients admitted to a tertiary hospital in Ghana. METHODS: A prospective cross-sectional study was conducted among one hundred and forty-five (145) consecutive patients admitted to the medical and the surgical wards at the Cape Coast Teaching Hospital (CCTH), Cape Coast, Ghana from April 2017 to April 2018. Socio-demographic and clinical information were collected using structured questionnaires. AKI was diagnosed and staged with the KDIGO guideline, using admission serum creatinine as baseline kidney function. RESULTS: The mean age of the study participants was 46.6±17.7 years, whilst the male:female ratio was 68:77. The overall incidence of AKI among the participants was 15.9% (95% CI: 10.33 - 22.84%). Stage 1 AKI occurred in 56.5% of the participants, whilst stages 2 and 3 AKI respectively occurred among 4.1% and 2.8% of respondents. About 20% of the participants in the medical ward developed AKI (n= 15) whilst 12% of those in surgical ward developed AKI (n= 8). Among the participants admitted to the medical ward, 60.0%, 26.7% and 13.3% had stages 1, 2 and 3 AKI respectively. Whilst 50.0%, 25.0% and 25.0% respectively developed stages 1, 2 and 3 AKI in the surgical ward. Medical patients with AKI had hypertension (40%), followed by liver disease (33.3%); 37.5% of surgical inpatients had gastrointestinal (GI) disorders. CONCLUSION: The incidence of AKI is high among medical and surgical patients in-patients in the CCTH, Ghana, with hypertension and liver disease as major comorbidities.

RESUMO

Sub-Saharan Africa, which has a population of more than 1 billion people, carries 24% of the global burden of disease and spends the least on health care of any region, relying heavily on international development assistance to deliver health care for HIV, tuberculosis, and malaria. The demographic and epidemiological transitions occurring in sub-Saharan Africa, with rising prevalences of obesity and diabetes, enhance the risk of non-alcoholic fatty liver disease (NAFLD), yet this remains an unrecognised complication of metabolic syndrome. There are no guidance documents on NAFLD from sub-Saharan Africa, and non-communicable disease (NCD) guidance documents do not include the associated burden of fatty liver disease. Combating the health and socioeconomic burden of NAFLD requires an integrated liver health approach, with task-shifting to primary health care. Using clear guidance documents to link education and management of HIV, viral hepatitis, NAFLD, and associated NCDs is also crucial to an integrated approach to infectious diseases and NCDs, which requires targeted funding from both governments and international development agencies.

RESUMO

Malaria-endemic areas of the world are noted for high morbidity and mortality from malaria. Also noted in these areas is the majority of persons in the population having acquired malaria immunity. Though this acquired malaria immunity does not prevent infection, it resists the multiplication of Plasmodium parasites, restricting disease to merely uncomplicated cases or asymptomatic infections. Does this acquired malaria immunity in endemic areas protect against other diseases, especially outbreak diseases like COVID-19? Does malaria activation of innate immunity resulting in trained or tolerance immunity contribute to protection against COVID-19? In an attempt to answer these questions, this review highlights the components of malaria and viral immunity and explores possible links with immunity against COVID-19. With malaria-endemic areas of the world having a fair share of cases of COVID-19, it is important to direct research in this area to evaluate and harness any benefits of acquired malaria immunity to help mitigate the effects of COVID-19 and any possible future outbreaks. FUNDING: None declared.

RESUMO

OBJECTIVES: The nutritional status of women affects pregnancy outcomes. Preconception care adequately prepares women for the demands of pregnancy. The aim of this study was to evaluate the prepregnancy iron status of nulliparous women in Ghana to provide empirical data to inform policy formulation. METHODS: We recruited 336 nulliparous women of reproductive age from Denkyembour District and Ejura Municipal assemblies, respectively, in the Eastern and Ashanti regions of Ghana. Serum ferritin was estimated to assess the women's iron stores. Hemoglobin (Hb) variants and fecal occult blood were determined for participants using cellulose acetate electrophoresis and lateral flow chromatographic immunoassay, respectively. Logistic regression analysis was used to determine factors associated with depleted iron stores (ferritin < 15 ng/dL). RESULTS: Whereas 41.5% of the women were anemic (Hb <11.5 g/dL), 34.5% were iron depleted (serum ferritin <15 g/mL; C-reactive protein <5 ng/dL). Also, 17.1% suffered from iron deficiency anemia (concomitant Hb <11.5 g/dL and serum ferritin <15 ng/dL). Serum ferritin significantly differed among the participants with anemia (P < 0.001). Multivariate regression analysis showed that age (<20 y: adjusted odds ratio [AOR], 13.916, P = 0.002; 20-30 y: AOR, 4.304, P = 0.023), moderate anemia (AOR, 3.045, P = 0.004), Ashanti region (AOR, 3.984, P = 0.002), and mean cell volume <80 fL (AOR, 2.546, P = 0.003) were significantly associated with increased odds of having depleted iron stores. However, body mass index, waist-to-hip ratio >0.85, educational status, or inherited Hb type were not significantly associated with depleted iron stores. CONCLUSION: The high prevalence of depleted iron stores in nulliparous women is a severe public health problem that requires attention.

RESUMO

The COVID-19 pandemic has impacted healthcare negatively across the globe. The practice of gastroenterology has been affected especially gastrointestinal (GI) endoscopy which is considered high risk for transmission of the virus. As a community of practitioners there is the need to share information and make evidence-based statements to guide GI practice in Ghana. This GASLIDD position statement based on the growing and rapidly evolving body of knowledge is to provide up to date information on the COVID-19 disease and guidance for the practice of gastroenterology in Ghana and beyond. It is to help the GI community of practice to maintain the highest level of health delivery and safety for our patients, staff, community and GI practitioners. FUNDING: Self-funded.
