Elevated rates of horizontal gene transfer in the industrialized human microbiome.

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.

A Review of Helicobacter pylori Diagnostics in Africa : From the Bedside to the Laboratory.

Helicobacter pylori (H. pylori) is endemic in Africa with a prevalence estimate of 79.1%. In addition, there is a significant community burden of dyspepsia in Africa, similar to other western countries. However, the majority of infected persons do not manifest the disease. In Africa, for instance, peptic ulcer disease is prevalent, whereas gastric cancer has reportedly low incidence. Therefore, it is important that testing is focused, targeting individuals most likely to benefit from treatment. In Africa, there are currently no guidelines for H. pylori testing and treatment. Empirical treatment is common due to variable access to diagnostics and health care. To assess the spectrum of H. pylori testing in Africa, we performed a literature search in PubMed over the past 10 years, 2013 to 2023. Histology was the most widely used modality in 16 out of 18 countries. Capacity for culture was shown in 11 studies, importantly across regions of Africa. H. pylori serology was demonstrated in 8 countries, although it has limited sensitivity in identifying active infection. H. pylori test-and-treat strategy has been shown to be cost-effective. Particularly in a region with high antibiotic resistance, adopting this strategy ensures that only confirmed positive patients are treated. Furthermore, test-of-cure ought to be mandatory to guide future therapies. Health authorities can leverage polymerase chain reaction facilities, left behind by the coronavirus disease 2019 pandemic, to make molecular susceptibility testing available in the near future. A systematic approach to testing incorporating indication for endoscopy and medication use is recommended.

A nationwide cross-sectional review of in-hospital hepatitis B virus testing and disease burden estimation in Ghana, 2016 - 2021.

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.

Ambulatory end-stage liver disease in Ghana; patient profile and utility of alpha fetoprotein and aspartate aminotransferase: platelet ratio index.

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.

Prevalence and risk factors of Hepatitis C virus infection in the Upper East Region of Ghana; a community-based cross-sectional study.

Hepatitis C virus (HCV) infection remains a major cause of liver related morbidity and mortality worldwide. Epidemiologic data on seroprevalence, viremia prevalence and risk factors remain limited in sub-Saharan Africa. In Ghana, HCV-related deaths are estimated to have increased since 2015. Risk factors associated with HCV infection in Ghana are not well described. The aim of this study was to determine the prevalence of, and risk factors associated with hepatitis C virus infection in the Upper East Region located in the northern part of Ghana. A community-based cross-sectional study was conducted in 9 communities in the Upper East region of Ghana. A total of 1,769 participants aged ≥12 years were screened for HCV antibody (anti-HCV) using rapid diagnostic testing (RDT). Seventy-four participants undertook HCV RNA testing after a positive anti-HCV result. Multivariate logistic regression was used to determine risk factors associated with HCV seropositivity. The anti-HCV prevalence was 8.4%, with 149 out of 1,769 testing anti-HCV positive. Mean age (±SD) of seropositive persons was 45.4 (±16.3) years. The highest anti-HCV seroprevalence was amongst persons aged 60 years and above. Forty-four out of 74 (59.5%) seropositive cases had viremic infection and the estimated viremic prevalence in the screened population was 5.0%. Predictors of HCV seropositivity were age (OR 1.03 95% CI 1.01-1.04), history of female genital mutilation or circumcision (OR 1.63 95% CI 1.04-2.55), sexual activity (OR 2.57 95% CI 1.38-4.79), positive maternal HCV status (OR 10.38 95% CI 4.13-26.05) and positive HIV status (OR 4.03 95% CI 1.35-12.05). In conclusion, the Upper East Region demonstrates a high Hepatitis C antibody prevalence. Almost 60% of individuals have viremic infection, however the cost of RNA testing is a barrier to virological diagnosis. There is a need to educate the population about HCV-associated risk factors to reduce HCV transmission and burden of disease.

GALAD Score for the Diagnosis of Hepatocellular Carcinoma in Sub-Saharan Africa: A Validation Study in Ghanaian Patients.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortality worldwide including sub-Saharan Africa. The GALAD score, derived from Gender, Age, Lens culinaris agglutinin-reactive fraction of alpha fetoprotein, Alpha fetoprotein, and Des-carboxy-prothrombin, has high accuracy in diagnosing HCC in Asia, Europe, and North America; however, it has not been validated in an African cohort. The aim of this study was to assess the performance of the GALAD score in the diagnosis of HCC in sub-Saharan Africa. Clinical data from patients with cirrhosis (n = 93) or HCC (n = 78) from outpatient hepatology clinics at three teaching hospitals in Ghana were abstracted, and serum samples were analyzed. A logistic regression model predicting HCC status based on the GALAD score was constructed to obtain the ROC curve for GALAD. The AUC with 95% confidence interval (CI) was calculated. The median GALAD score was higher among patients with HCC versus cirrhosis controls (8.0 vs. -4.1, P < 0.01). The AUC of the GALAD score for HCC detection was 0.86 (95% CI, 0.79-0.92). At a cut-off value of -0.37, the GALAD score had a sensitivity of 0.81 and a specificity of 0.86. The AUC (95% CI) was 0.87 (0.80-0.95) and 0.81 (0.67-0.94) in hepatitis B virus-positive and hepatitis B virus-negative patients, respectively. The GALAD score has a high accuracy for HCC detection. It has great potential to improve HCC surveillance in sub-Saharan Africa where imaging resources are limited. Significance: The GALAD score or its relevant modifications have the potential to aid in improving HCC surveillance efforts in low-resource settings in sub-Saharan Africa. This could enhance early detection rates of HCC and potentially improve survival rates in resource-limited settings.

Clinical Profile and Limitations in the Management of HBV Patients Attending Clinic at a District Hospital in Ghana.

Background: Chronic hepatitis B (CHB) is estimated to cause between 500,000 and 1.2 million deaths worldwide every year through cirrhosis and hepatocellular carcinoma (HCC). Liver cirrhosis and HCC are the commonest liver diseases causing death in Ghana. The most critical problem in the management of CHB in sub-Saharan Africa is the high cost of investigations and antiviral drugs. There is scanty information concerning newly diagnosed CHB patients and their management challenges in Ghana. This study sought to determine the clinical characteristics and management challenges of CHB patients in Ghana. Methodology. A prospective cohort study was conducted involving newly diagnosed CHB patients being managed at St. Dominic Hospital. Patient demographic and clinical features were abstracted using a standardized questionnaire. The proportion of patients able to undertake investigations and treatment were determined, and the limitations to standard management were recorded. The performance of APRI score in the diagnosis of cirrhosis was also investigated. Results: Of the 334 patients with newly diagnosed CHB, the median age at diagnosis was 35 (IQR 28-44) years. Less than a quarter (22.2%) were able to undertake viral load testing and 23.4% were eligible for treatment. Of those who were eligible for treatment, only 42.3% were able to initiate treatment. Almost a third of cases (32.1%) reported late with liver-related complications. The sensitivity of APRI score with cut-off value of 2 in the diagnosis of liver cirrhosis was 70.2% and specificity was 97.9%. Conclusion: A high proportion of newly diagnosed CHB patients presented late and with liver-related complications. Majority were not able to afford viral load testing and antiviral medication. Screening of hepatitis B among the general population and inclusion of CHB management in the National Health Insurance Scheme should be encouraged.

Hepatitis C virus seroprevalence, testing, and treatment capacity in public health facilities in Ghana, 2016-2021; A multi-centre cross-sectional study.

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.

Acute Kidney Injury in Patients with Liver Cirrhosis: Prevalence, Predictors, and In-Hospital Mortality at a District Hospital in Ghana.

BACKGROUND: Acute kidney injury (AKI) is one of the most severe complications of cirrhosis and portends an ominous prognosis with an estimated mortality of about 50% in a month and 65% within a year. Infection and hypovolemia have been found to be the main precipitating factors of AKI in liver cirrhosis. Early detection and treatment of AKI may improve outcomes. AKI in patients with liver cirrhosis in Ghana and their impact on inpatient mortality are largely unknown. This study was aimed at determining the prevalence, precipitating factors, predictors, and in-hospital mortality of AKI in patients with liver cirrhosis admitted to a district hospital in Ghana. METHODS: Consecutive hospitalized patients with liver cirrhosis from 1 January 2018 to 30 April 2020 were recruited. Patient's demographic data and clinical features were collected using a standardized questionnaire. Biochemical and haematological tests as well as abdominal ultrasound scans were done for all patients. All patients were then followed up until discharge or death. RESULTS: There were 117 (65.4%) males out of the 179 patients with a mean age of 49.94 and 45.84 years for those with and without AKI, respectively. The prevalence of AKI was 27.9% (50/179). Out of 50 participants with AKI, 64.0% (32/50) died, contributing 41.0% of all in-patient mortality amongst participants. There was a significant association between AKI and death (p ≤ 0.001). The major precipitating factors of AKI were infections (60.0%), hypovolemia (20.0%) due to gastrointestinal bleeding and gastroenteritis, and refractory ascites (16.0%). Alkaline phosphatase, INR, model for end-stage liver disease sodium, sodium, and blood urea nitrogen were independent predictors of AKI. CONCLUSION: AKI was common among patients with liver cirrhosis with high in-patient mortality. Identification of these precipitants and independent predictors of AKI may lead to prompt and targeted treatment with reduction in patient mortality.

Sociodemographic characteristics, complications requiring hospital admission and causes of in-hospital death in patients with liver cirrhosis admitted at a district hospital in Ghana.

BACKGROUND: Chronic liver diseases including liver cirrhosis are a major cause of morbidity and mortality globally. Despite the high burden of liver cirrhosis in Ghana, data on this disease is lacking. OBJECTIVE: To determine the sociodemographic characteristics, reasons for admission, and in-hospital mortality of patients with cirrhosis of the liver seen at a district hospital in Ghana. METHODS: A prospective study was conducted involving one hundred and eighty-six (186) patients admitted on the medical wards in St. Dominic hospital with liver cirrhosis from 1st January 2018 to 24th June 2020. The patient's demographic and clinical features were documented using a standardized questionnaire. Diagnostic biochemical and haematological tests as well as abdominal ultrasound scans were performed for all patients. They were followed up until death or discharge from hospital. RESULTS: One hundred and eighty-six patients (186) with a median age of 46 years were included in the study. HBV was the main etiology of liver cirrhosis (38.7%) followed closely by alcohol consumption (38.3%). In-hospital mortality was 41.3% and the most frequent cause of death was hepatic encephalopathy (68.4%). The following were associated with death; Jaundice, weight loss, elevated bilirubin, international normalized ratio (INR), creatinine, blood urea nitrogen(BUN), Child-Pugh score, model for end-stage liver disease sodium score (MELDNa), and low sodium. However, hepatic encephalopathy, MELDNa, INR and BUN were independent predictors of in-hospital mortality on logistic regression analysis. CONCLUSIONS: In-hospital mortality in cirrhotic patients was high with the leading cause of death being hepatic encephalopathy. Timely diagnosis and adequate management of hepatic encephalopathy are necessary to prevent death from liver cirrhosis.

The Prevalence, Predictors, and In-Hospital Mortality of Hepatic Encephalopathy in Patients with Liver Cirrhosis Admitted at St. Dominic Hospital in Akwatia, Ghana.

Background: Hepatic encephalopathy (HE) is one of the most debilitating complications of cirrhosis leading to death. Decrease in HE mortality and recurrence has been linked with timely identification and early treatment. There is a need to document the burden, predictors, and treatment outcomes of HE in an adult population with liver cirrhosis in our setting as only reports from resource-endowed countries abound in the literature. This study aimed therefore to determine the prevalence, predictors, and treatment outcomes of patients with liver cirrhosis admitted at St. Dominic Hospital (SDH) in Akwatia, Ghana. Materials and Methods: A prospective study was conducted involving one hundred and sixty-seven (167) patients admitted at the medical wards in SDH with liver cirrhosis from January 1st, 2018, to March 24th, 2020. The demographic and clinical features of the patients were collected using a standardized questionnaire. Biochemical, haematological, and abdominal ultrasound scans were done for all patients. Patients were then followed up until discharge or death. Results: There were 109 (65.3%) males out of the 167 patients with a mean age of 45.8 and 47.5 years for those with and without HE, respectively. The prevalence of HE was 31.7% (53/167). Out of 53 participants with HE, 75.5% (40/53) died. There was a strong association between HE and death (p < 0.001). The major precipitating factor of HE was infection (64.2%). Severe ascites (OR = 0.009) were clinical feature independently associated with HE, whereas high creatinine (OR = 0.987), blood urea nitrogen (BUN) (OR = 1.199), Child-Pugh score (CPS) (OR = 5.899), and low platelets (OR = 0.992) were the laboratory parameters and scores independently predictive of HE. Conclusion: HE was common among patients with liver cirrhosis admitted at SDH with high in-patient mortality. The commonest precipitating factor for HE was infection(s). Severe ascites, low platelet count, high creatinine, BUN, and CPS were independent predictors of HE.

Gastroenterology practice in the COVID-19 era: Ghana Association for the Study of Liver and Digestive Diseases (GASLIDD) position statement.

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.

Spontaneous bacterial peritonitis among adult patients with ascites attending Korle-Bu Teaching Hospital.

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is one of the most common and life-threatening complications of ascites, mostly in patients with cirrhotic ascites and children with nephrotic syndrome. Recognition and prompt treatment of this condition is essential to prevent serious morbidity and mortality. It is therefore important to determine the prevalence of SBP among in-patients with ascites attending our facility and to determine the clinical characteristics associated with SBP among these patients. METHODS: A cross-sectional study was conducted involving 140 patients with ascites irrespective of the underlying cause from 25th March 2016 to 25th November 2016. Demographic information and clinical data were collected using a standardized questionnaire. Ascitic fluid culture, the gold standard for SBP diagnosis and ascitic fluid cell count was done. Positive ascitic fluid culture and/ or ascitic polymorpho nuclear leukocyte ≥250cells/mm3 were diagnostic for SBP. RESULTS: Of the 140 patients with ascites the mean age was 44.7±13.2 years. There were seventy six (76) male and sixty four (64) female patients. The prevalence of SBP was 21.43% (30/140). Majority, (41.7%) of the bacteria isolated from ascitic fluid with SBP was Escherichia coli. History of jaundice, low arterial blood pressure on admission and encephalopathy were found to be independent predictors of SBP. CONCLUSION: SBP is common among patients with ascites admitted at the Korle-Bu Teaching Hospital. Jaundice, encephalopathy and low blood pressure are highly suggestive of SBP and diagnostic paracentesis should be done immediately on admission to confirm the diagnosis. FUNDING: None.

Prevalence and predictors for spontaneous bacterial peritonitis in cirrhotic patients with ascites admitted at medical block in Korle-Bu Teaching Hospital, Ghana.

INTRODUCTION: Spontaneous bacterial peritonitis (SBP) is one of the most common and life-threatening complications of patients with cirrhotic ascites. Recognition and prompt treatment of this condition is essential to prevent serious morbidity and mortality. This study aimed to determine the prevalence of SBP among in-patients with cirrhotic ascites attending our facility and to determine the clinical and laboratory parameters associated with SBP. METHODS: A cross-sectional study was conducted involving one hundred and three (103) patients admitted at medical block in the Korle-Bu Teaching Hospital (KBTH) with cirrhotic ascites from 25th March, 2016 to 25th November, 2016. Demographic and clinical data were collected using a standardized questionnaire. Ascitic fluid culture and cell count were conducted. Positive ascitic fluid culture and/or ascitic polymorphonuclear leukocyte ≥ 250cells/mm3 were diagnostic for SBP. RESULTS: Of the 103 patients with cirrhotic ascites, the mean age was 43.5 ± 12.2 years. There were fifty eight (58) male patients. The prevalence of SBP was 25.24% (26/103). Majority, 5 (55.6%) of the bacteria isolated from ascitic fluid with SBP was Escherichia coli. Severe ascites and high INR were found to be independent predictors of SBP. CONCLUSION: SBP is common among patients with cirrhotic ascites admitted at KBTH. Severe ascites and high INR were highly suggestive of SBP. Diagnostic paracentesis should be done immediately on admission to confirm the diagnosis irrespective of the clinical characteristics as part of baseline investigation.

Indications and findings of upper gastrointestinal endoscopy in patients presenting to a District Hospital, Ghana.

INTRODUCTION: Upper gastrointestinal (UGI) symptoms are among the commonest complaints for which patients seek medical attention. Characteristics of patients undergoing UGI endoscopy (UGIE) at the district hospital in Ghana are largely unknown. This study was to document the demographic characteristics, indications and endoscopic findings of patients undergoing UGIE at the district hospital in Ghana. METHODS: This study used a cross-sectional design to consecutively recruit 371 patients referred to the Endoscopy Unit of the St. Dominic Hospital, Akwatia for UGIE. Demographic data and indications for the UGIE were recorded. Endoscopic findings per each participant were recorded. Helicobacter pylori (H. pylori) infection was confirmed by rapid-urease examination of gastric antral and body biopsies at endoscopy. RESULTS: There were 159(42.9%) males out of the 371 patients. The age ranged from 4 to 94 years with a median age of 46 years. Dyspepsia was the commonest indication occurring in 282(76.0%) patients. The commonest endoscopic diagnosis was gastritis which occurred in 261(70.4%) patients. The prevalence of H. pylori obtained by immediate rapid-urease-campylobacter like- organism (CLO) test was 44.9%. CONCLUSION: The main indication for UGIE in the studied patients was dyspepsia and most of these patients had gastritis on endoscopy. Only few patients had normal findings. The prevalence of H. pylori in this population was low compared with most of the previous studies done in the country. There is the need to establish more endoscopy centres within the district hospitals in the country and more health professionals trained to perform them.

Non-invasive markers as predictors of oesophageal varices in cirrhotic patient in a teaching hospital in Ghana.

INTRODUCTION: Oesophageal variceal (OV) bleeding is a potentially fatal consequence of portal hypertension in patients with liver cirrhosis. Upper GI endoscopy is recommended for screening for varices in cirrhotics for early detection and treatment, however, this is invasive. The purpose of this study was to assess the predictive values of the noninvasive tests in detecting the presence of OV. METHODS: A cross-sectional hospital-based study involving 149 patients with liver cirrhosis was carried out at the Korle-Bu Teaching Hospital from 1st November 2015 to 25th November 2016. Relevant clinical parameters assessed included Child-Pugh class, ascites and splenomegaly. Full blood count and liver function tests, abdominal ultrasound and gastroscopy were done for all the participants. Receiver operating characteristic curve was generated to determine the cut-off values for the best sensitivity, specificity, negative and positive predictive values of the variables (serum albumin, platelet count (PC), aspartate aminotransferase (AST)/alanine aminotransferase (ALT), PC/Spleen diameter( SD)) with regard to the presence of OV. RESULTS: On gastroscopy, 135 (90.60%) had OV and 14 patients (9.40%) had no OV. One hundred and eleven of the varices (82.22%) were large varices and the rest (17.78%) small varices. The overall mean of serum albumin, PC and PC/SD were not significant predictors of the presence of OV. However, the overall mean of AST/ALT significantly predicted the presence of OV. A PC/SD cut off value of ≤833.3 had 72.62% diagnostic accuracy for diagnosing all OV. CONCLUSION: PC/SD cut-off could be used to screen cirrhotics for OV and treatment initiated in geographical areas lacking endoscopy facilities. FUNDING: None declared.

Hepatitis B mother-to-child transmission in the Eastern Region of Ghana: a cross-sectional pilot study.

INTRODUCTION: Hepatitis B is a major health concern in Ghana, where prevalence of the virus remains high and most chronic patients are infected during childhood or at birth. This study aimed to determine the prevalence and main factors associated with mother-to-child transmission of hepatitis B in the context of Ghana. METHODS: In this cross-sectional pilot study, we tested infants born to hepatitis B positive mothers at a hospital in the Eastern Region of Ghana to determine the prevalence of mother-to-child transmission. A questionnaire was completed by hepatitis B positive mothers to investigate the association between factors surrounding the birth of the child and whether transmission had occurred. These factors were analyzed independently using Fisher's exact test. To investigate the relationship between mother's age at the time of delivery and viral transmission, a univariate logistic regression analysis was performed. RESULTS: The prevalence of mother-to-child transmission was 5.9%, with 51 hepatitis B positive mothers included in the study and three infants testing positive. A majority of infants received the standard hepatitis B vaccination schedule (96.1%) while two-thirds received the birth dose. There was no significant association observed between the clinical interventions reported in the study and mother-to-child transmission. No significant association was observed between the age of the mother at the time of delivery and viral transmission (OR: 1.077, 95% CI: 0.828 - 1.403, p = 0.58). Viral marker testing during pregnancy was absent in the population and could not be reliably assessed. CONCLUSION: There was a low prevalence of HBV mother-to-child transmission observed despite a clear absence of viral marker and viral load testing. It is recommended that viral profile analysis is performed for hepatitis B positive pregnancies to identify high risk cases.

Nutritional management of cirrhosis patients: A qualitative study exploring perceptions of patients and health workers in Ghana.

BACKGROUND AND AIMS: Malnutrition is common among patients with end stage liver disease including liver cirrhosis and liver cancer. Optimal nutrition is important to reduce morbidity and mortality of these patients. There is limited qualitative data on nutritional status and management of chronic liver disease patients. We aimed to explore the knowledge, opinions and practices of cirrhosis patients and health workers in nutritional management of cirrhosis in Ghana, in order to determine whether there is a need to improve nutritional care for cirrhosis patients. METHODS: We conducted a qualitative study using semi-structured interviews of cirrhotic patients (n = 16) and healthcare providers (n = 27) in three academic centers in Accra, Kumasi and Cape Coast (Ghana). Recruitment was by purposive sampling of patients attending specialist liver disease clinics. The recorded data were analyzed using NVivo 11 software, with generation of codes, themes and subthemes. RESULTS: The major themes that emerged from the data included nutrition as part of care delivery during the hospital visit, nutritional recommendations, dietary changes and long-term practice improvement. The results showed that patients and health workers felt dietary recommendations for patients were frequently addressed, but could be significantly improved. We found that in the opinion of study participants, local guidelines are important and necessary in nutritional management of cirrhosis patients, and that participants felt it was difficult to change dietary habits following cirrhosis diagnosis. CONCLUSIONS: These results suggest that nutritional management of cirrhosis patients in Ghana requires improvement. Strategies to improve this could include a multi-disciplinary approach to nutritional management, development of local guidelines and continued nutritional assessment, monitoring and follow-up.

Oesophageal varices in patients with liver cirrhosis attending a major tertiary hospital in Ghana.

INTRODUCTION: Oesophageal variceal bleeding is a potentially fatal consequence of portal hypertension in cirrhotic patients. In Ghana, bleeding oesophageal varices (OV) are a significant cause of acute upper gastrointestinal bleeding with comparatively high mortality. This study was to determine the prevalence of OV and its clinical correlate in cirrhotic patients. METHODS: This was a cross sectional hospital based study of 149 subjects with liver cirrhosis from 5thNovember, 2015 to 4th November, 2016. Demographic and other clinical data were collected using standardized questionnaire. Liver function, full blood count, HBsAg and anti-HCV Ab tests were done for all patients. All patients underwent an abdominal ultrasound to assess liver and document ascites. Upper GI endoscopy (UGIE) was done to screen for and grade varices. RESULTS: A total of 149 patients with a mean age of 45 ± 12.28 years were evaluated. There were 77.85% and 22.15% men and women respectively, with a male to female ratio of 3.5:1. By Child-Pugh Classification, 12 (8.16%) patients were in class A, 64 (43.54%) in class B and 71 (48.3%) in class C at presentation. On UGIE, 135 (90.60%) had varices and 14 patients (9.40%) had no varices. One hundred and eleven of the varices (82.22%) were large varices and the rest (17.78%) small varices. CONCLUSION: Majority of cirrhotic patients present late with advance disease to this referral centre. Most have large varices on their first screening endoscopy. Prophylactic treatment should be considered for all cirrhotics especially patients with decompensated liver cirrhosis when UGIE cannot be done immediately.
