Disorder of Glucose Metabolism and Therapy: Implications on the Natural History of Advanced Chronic Liver Disease

Introduction: Hepatogenous diabetes (HD) is a disorder of glucose metabolism (DGM) that develops as a complication of advanced chronic liver disease (ACLD) with an estimated prevalence of 20–70%. It appears to be associated with a larger number of decompensations, but its impact on the natural history of the disease is unclear. The treatment of DGM is hampered by the fact that some therapeutic agents are associated with a risk of complications in ACLD. The aim of this work was to study DGM in a population of patients with ACLD: prevalence, liver disease decompensation episodes, mortality analysis and study of the impact of antidiabetic therapies in patients with ACLD who developed DGM. Materials and Methods: A cohort of consecutive patients with ACLD without previous DGM, who attended a Hepatology clinic in the period of January to June 2015 was selected. Follow-up was carried out for 5 years. Data on age, gender, date of diagnosis and etiology of ACLD, Child-Pugh and MELD-Na classifications at enrollment, development of DGM, and antidiabetic therapy were collected. Logistic regression models for hospitalizations due to decompensated ACLD, ascites, hepatic encephalopathy (HE), upper gastrointestinal bleeding (UGB), hepatocellular carcinoma (HCC), portal vein thrombosis (PVT), infectious complications, acute-on-chronic liver failure (ACLF), and death were built. A survival analysis for patients with and without DGM was also performed. Treatment effectiveness for patients with DGM was assessed. Results: Initially, 221 patients were included, 154 (69.7%) of whom developed DGM after the diagnosis of ACLD. DGM patients presented a significantly higher number of hospitalizations. Odds ratio (OR) for death was not significantly related with DGM. At 5 years of follow-up, 68.9% of patients with DGM were alive, against 81.8% without DGM (p = 0.087). From the 154 patients who were diagnosed with DGM, 42.9% were not receiving pharmacological treatment for DGM. Treated patients were prescribed with either biguanides (34.8%), a SGLT2 inhibitor (8.6%), or insulin (7.7%). Only 1 patient was treated with a GLP-1 analogue. A tendency of OR favoring treatment was observed for biguanides and SGLT2 inhibitors in all outcomes except ascites. In the univariable analysis, the use of biguanides was associated with lower risk of death (OR: 0.84 [95% CI: 0.73–0.96]) and HE (OR: 0.85 [95% CI: 0.73–0.98]). Conclusion: DGM occurs with high prevalence in patients with ACLD and it seems to be related to more hospitalizations, which highlights the importance of its early identification and appropriate therapeutic approach. In the absence of contraindications, biguanides should be considered for treatment of patients with ACLD and DGM as they appear to be associated with a tendency to better outcomes and may present some advantage in terms of survival.

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.

Association between khat chewing and high viral load in chronic hepatitis B infection

Background and aims: chronic hepatitis B infection (CHB) is a worldwide health threat that has moderate to high prevalence in Yemen. There is accumulating evidence of the hepatotoxicity of khat, which is commonly and habitually chewed in Yemen and elsewhere, but little is known in CHB. This study aimed to examine the association between khat chewing and hepatitis B virus (HBV) serum DNA level (viral load) in such cases. Methods: Between January and December 2016, a cross-sectional study was carried out on consecutively consenting 210 CHB participants (khat chewers and non-cutters) attending the hepatology clinics of two major hospitals in Sana’a city. After a structured interview, blood samples were collected for the determination of HBV markers and HBV load. Results: the study population, residing different cities in Yemen, had a median age of 36y (range = 20-72) with a 2.9:1 male to female ratio. Viral load was significantly (P&lt;0.001) higher among khat chewers than non chewers: median (Interquartile range) = 1308 (531.5-5916.5) vs 177 (60-627) IU/ml. Khat chewing was observed, via multivariate logistic regression analysis, to be significantly (pThe0.001) and independently associated with a clinically significant high HBV load (&gt;2000 IU/ml) even after adjustment for the studied socio-demographic and laboratory factors. Conclusion: This study suggests khat chewing, especially on a daily basis, as a potential risk factor for high viremia and, therefore, be prudently discouraged in CHB.

Outcomes of a 1-Year Pilot Study Implementing Universal Hepatitis Delta Virus Testing Among Veterans With Chronic Hepatitis B.

Current US guidelines recommend risk-based testing for hepatitis delta virus (HDV) in persons with chronic hepatitis B (CHB). While there is debate as to whether a risk-based or universal testing approach is most effective, limited data exist on universal HDV testing programs in the United States. We performed a 1-year pilot study evaluating the outcomes of a universal HDV testing approach among US veterans with CHB. All consecutive adults with CHB receiving care at hepatology clinics at a single-centre Veterans Affairs Health System from 1 October 2022 to 30 September 2023 were prospectively tested for anti-HDV antibody (anti-HDV). Patients who were anti-HDV Ab-positive were subsequently tested for HDV RNA. Comparison of HDV testing between groups utilised chi-square testing. A total of 91 consecutive CHB patients (90.0% male, mean age 60.9 ± 14.1 years, 73.9% Asian, 26.1% non-Asia, 16.5% cirrhosis and 17.1% with active or past history of drug use) had anti-HDV ordered. Overall, 76.9% (n = 70) completed anti-HDV testing; 4.3% (n = 3) were positive. HDV RNA testing was ordered in all three patients; two patients completed HDV RNA testing and one had detectable HDV RNA. No significant differences in completion of anti-HDV testing was observed by age, sex, race/ethnicity, cirrhosis status or drug use history. Among a single-centre prospective cohort study piloting a universal HDV testing approach, one patient with viremic HDV was identified. Implementing true reflex testing of all CHB patients with anti-HDV, followed by automated HDV RNA testing for anti-HDV-positive patients would improve the HDV testing cascade and timely diagnosis of HDV.

Distinct Longitudinal Trajectories of Symptom Burden Predict Clinical Outcomes in End-Stage Liver Disease.

Little has been reported about the clinical relevance and trajectories of symptoms in end-stage liver disease (ESLD). The purpose of this prospective study was to identify trajectories of change in symptom burden over the course of 12 months in adults with ESLD. Patients were recruited from hepatology clinics at 2 healthcare systems. Validated measures were used to assess physical and psychological symptoms. Latent growth mixture modeling and survival and growth modeling were used to analyze the survey data. Data were available for 192 patients (mean age 56.5 ± 11.1 years, 64.1% male, mean Model for ESLD (MELD) 3.0 19.2 ± 5.1, ethyl alcohol as primary etiology 33.9%, ascites 88.5%, encephalopathy 70.8%); there were 38 deaths and 39 liver transplantations over 12 months. Two symptom trajectories were identified: 62 patients (32.3%) had high and unmitigated symptoms, and 130 (67.7%) had lower and improving symptoms. Patients with high and unmitigated symptoms had twice the hazard of all-cause mortality (subhazard ratio 2.53, 95% confidence interval: 1.32-4.83) and had worse physical ( P < 0.001) and mental quality of life ( P = 0.012) compared with patients with lower and improving symptoms. Symptom trajectories were not associated with MELD 3.0 scores ( P = 0.395). Female sex, social support, and level of religiosity were significant predictors of symptom trajectories ( P < 0.05 for all). There seems to be 2 distinct phenotypes of symptom experience in patients with ESLD that is independent of disease severity and associated with sex, social support, religiosity, and mortality. Identifying patients with high symptom burden can help optimize their care.

Medication burden and anticholinergic use are associated with overt HE in individuals with cirrhosis.

Polypharmacy and anticholinergic medications are associated with cognitive decline in elderly populations. Although several medications have been associated with HE, associations between medication burden, anticholinergics, and HE have not been explored. We examined medication burden and anticholinergics in patients with cirrhosis and their associations with HE-related hospitalization. We conducted a retrospective cohort study of patients aged 18-80 with cirrhosis seen in hepatology clinics during 2019. The number of chronic medications (medication burden) and anticholinergic use were recorded. The primary outcome was HE-related hospitalization. A total of 1039 patients were followed for a median of 840 days. Thirty-seven percent had a history of HE, and 9.8% had an HE-related hospitalization during follow-up. The mean number of chronic medications was 6.1 ± 4.3. Increasing medication burden was associated with HE-related hospitalizations in univariable (HR: 1.09, 95% CI: 1.05-1.12) and multivariable (HR: 1.07, 95% CI: 1.03-1.11) models. This relationship was maintained in those with baseline HE but not in those without baseline HE. Twenty-one percent were taking an anticholinergic medication. Anticholinergic exposure was associated with increased HE-related hospitalizations in both univariable (HR: 1.68, 95% CI: 1.09-2.57) and multivariable (HR: 1.71, 95% CI: 1.11-2.63) models. This relationship was maintained in those with baseline HE but not in those without baseline HE. Anticholinergic use and medication burden are both associated with HE-related hospitalizations, particularly in those with a history of HE. Special considerations to limit anticholinergics and minimize overall medication burden should be tested for potential benefit in this population.

Predictive Risk Factors and Scoring Systems Associated with the Development of Hepatocellular Carcinoma in Chronic Hepatitis B.

Chronic hepatitis B (CHB) infection constitutes a leading cause of hepatocellular carcinoma (HCC) development. The identification of HCC risk factors and the development of prognostic risk scores are essential for early diagnosis and prognosis. The aim of this observational, retrospective study was to evaluate baseline risk factors associated with HCC in CHB. Six hundred thirty-two consecutive adults with CHB (n = 632) [median age: 46 (IQR: 24)], attending the outpatients' Hepatology clinics between 01/1993-09/2020 were evaluated. Core promoter mutations and cirrhosis-HCC (GAG-HCC), Chinese University-HCC (CU-HCC), risk estimation for hepatocellular carcinoma in chronic hepatitis B (REACH-B), Fibrosis-4 (FIB-4), and Platelet Age Gender-HBV (PAGE-B) prognostic scores were calculated, and receiver operating curves were used to assess their prognostic performance. HCC was developed in 34 (5.38%) patients. In the multivariable Cox regression analysis, advanced age (HR: 1.086, 95% CI: 1.037-1.137), male sex (HR: 7.696, 95% CI: 1.971-30.046), alcohol abuse (HR: 2.903, 95% CI: 1.222-6.987) and cirrhosis (HR: 21.239, 95% CI: 6.001-75.167) at baseline were independently associated with the development of HCC. GAG-HCC and PAGE-B showed the highest performance with c-statistics of 0.895 (95% CI: 0.829-0.961) and 0.857 (95% CI: 0.791-0.924), respectively. In the subgroup of patients with cirrhosis, the performance of all scores declined. When treated and untreated patients were studied separately, the discriminatory ability of the scores differed. In conclusion, HCC development was independently associated with advanced age, male sex, alcohol abuse, and baseline cirrhosis among a diverse population with CHB. GAG-HCC and PAGE-B showed high discriminatory performance to assess the risk of HCC development in these patients, but these performances declined in the subgroup of patients with cirrhosis. Further research to develop scores more specific to certain CHB subgroups is needed.

Non Invasive Assessment of Pulmonary Artery Pressure in Children with Portal Hypertension

Abstract Background Pulmonary artery hypertension is a complication of liver cirrhosis with Portal Hypertension (PHT). It has been mentioned in case reports or small series of children. Fewinformation known on its prevalence and long-term survival in childhood liver disease. This study will assess the Pulmonary Atery Pressure (PAP) in children with PHT in Pediatric Hepatologyclinic, Ain Shams University Children Hospital in order to identify clinical characteristics of Porto PH and its prevalence among those children. Aim of the Work To assess the PAP using Echocardiography in children with PHT who attend Pediatric Hepatology clinic, Ain Shams University Children Hospital. Patients and Methods This case-control study was conducted on thirty patients enrolled from Pediatric Hepatology clinic, Ain Shams University Children Hospital in a period of one year from June 2021 to June 2022 according to inclusion criteria : history of hematemesis and melena, clinical examination: Splenomegaly, dilated anterior abdominal wall vessels, ascites ± firm hepatomegaly and imaging: Ultrasonography (US) /color Doppler-US (CDUS): Splenomegaly, presence of Porto collateral vessels and ascites. This information will be completed with data on liver size, echo texture, and margins which can suggest underlying cirrhosis, portal vein diameter, portal blood flow velocity, direction of blood flow in portal vein with age ranging from 1 to 16 years with median (IQR) of 8 (4.5-12) years; they were 11 females (36.7%) and 19 males (63.3%) and thirty healthy matched age and sex as a control group. Results In our study, MPAP was 9.79 ± 2.21 mmHg (7.2-18.2 mmHg). Statistically, there was statistically significant increase in the level of TR velocity, TR PG, RVSP and MPAP in patients with PHT than control group with p-value &amp;lt;0.001, 0.001; 0.001 and &amp;lt;0.001; respectively. Also, there was statistically significant increase in the percentage of patients with abnormal TR PG and patients with elevated systolic PAP in patients with PHT (20.0%) than control group (0.0%) with p-value = 0.010 and 0.010; respectively. Also, there was statistically significant decrease in the level of PA acceleration time (ms) in patients with PHT than control group with p-value &amp;lt;0.001. Also, there was statistically significant increase in the level of PAEDP (mmHg) and LA (cm) in patients with PHT than control group with p-value &amp;lt;0.001 and 0.014; respectively. In our studied group of patients we did not found any of them has PH despite the higher parameters of their Echo studies and that needs follow up of those patients. So the prevalence of PH in those patients is 0%. Conclusion PHT is an important risk factor of development of PH in children. Transthoracic echocardiography can be reliably used as an initial non-invasive, safe and reliable modality for the assessment of pulmonary artery hypertension in children, and can obviate the need of right heart catheterization in some patients, especially those with mild PHT.

Association between Autoimmune Hepatitis and Celiac Disease among Egyptian Children and Adolescents

Abstract Background Celiac disease (CD) is an immune-mediated intolerance to gluten .CD has been recognized as a multisystem disorder which may affect other extra intestinal organs, such as the skin, thyroid, heart, nervous system, pancreas and liver. Individuals with CD are at increased risk of liver disease namely cryptogenic liver disorder and autoimmune liver disorder. However, until now, it remains unknown whether these two forms of liver disease are really different entities or only different severities of the same disorder. Objective To evaluate the association of CD with autoimmune hepatitis in pediatrics. Subjects and Methods This was a cross-sectional study that was conducted at the Pediatric Hepatology Clinic and Pediatric Gastroenterology Clinic, Children’s Hospital, Ain Shams University. The study included 2 groups of patients each comprised 20 children and adolescents as follow: Group I: Patients with established diagnosis of autoimmune hepatitis (AIH). All patients were receiving corticosteroids and azathioprine Group II: Patients with established diagnosis of CD. In group I patients with AIH, CD was screened for using anti-tissue transglutaminase (tTG) IgA in addition to measuring serum IgA to determine the need to measure anti-tTG IgG. Immunological markers (ANA, anti-smooth muscle antibody (ASMA) and liver and kidney microsomal (LKM) antibodies in addition to protein electrophoresis were done for group II patients with CD to screen for AIH. Results All patients in group I with AIH had normal serum IgA levels and were found negative for anti-tTG IgA. Also, group II patients with CD were negative for ANA, ASMA and LKM antibodies with normal protein electrophoresis. Conclusion The current study showed that CD does not seem to have significant association with AIH, however, the small sample size is a study limitation. Further wider scale studies are needed to evaluate the risk of AIH in CD.

Psychological processes and alcohol reduction in patients with chronic hepatitis C: Results from the HepART trial.

There is a lack of randomized controlled trials of behavioral interventions and process-level research related to alcohol reduction among patients with chronic liver disease (e.g., hepatitis C viral (HCV) infection). We conducted a process-level, secondary analysis of the Hepatitis C-Alcohol Reduction Treatment (HepART) trial to investigate the association between change in psychological processes posited by the Integrated Behavioral Model (IBM) and change in World Health Organization (WHO) drinking risk levels. Patients with HCV who consume alcohol were recruited from hepatology clinics and received provider-delivered SBIRT (Screening, Brief Intervention, Referral to Treatment) or SBIRT+ 6 months of co-located alcohol counseling. Treatment arms were combined for this analysis because no between-group differences were found. At baseline and 6 months, the timeline followback method was used to determine alcohol risk levels according to the 2000 WHO risk categories (based on average grams of alcohol per day). Changes in alcohol consumption and WHO risk levels were quantified and regressed on change in individual psychological processes (e.g., readiness, self-efficacy, motives, attitudes, and strategies) from baseline to 6 months. At the baseline assessment, 162 participants were classified as abstinent (5%), low (47%), moderate (16%), high (19%), or very high (13%) WHO risk levels. At 6 months, 38% remained at the same risk level and 48% decreased by at least one level. In univariate analyses, changes in 7 of 12 psychological processes were associated with change in risk levels. Adjusted multivariate analyses demonstrated that change in four processes were significantly associated with change in risk levels, including SOCRATES Taking Steps, Ambivalence, and Recognition scores and alcohol reduction strategies. These findings demonstrate significant reductions in quantitative indices of alcohol consumption following opportunistic alcohol interventions in patients with HCV. However, results provided mixed support for associations between change in IBM psychological processes and alcohol consumption.

BRIDGE to liver health: implementation of a group telehealth psychoeducational program through shared medical appointments for MASLD management

BackgroundMetabolic dysfunction-associated steatotic liver disease (MASLD) represents a significantly costly and increasingly prevalent disease, with treatment focused on lifestyle intervention. Integrating education and behavioral health into clinical care offers opportunities to engage and empower patients to prevent progression of liver disease. We describe the design and implementation of Behavioral Resources and Intervention through Digital Group Education (BRIDGE), a 6-session group telehealth program led by advanced practice providers (APPs) in 90-min shared medical appointments (SMAs) with small groups of MASLD patients in an academic outpatient hepatology clinic. The program contains multi-component group interventions, with didactic education and behavioral coaching, while leveraging peer-based learning and support.MethodsA mixed-methods exploratory pilot study was conducted. Feasibility and acceptability of the clinical intervention were assessed by tracking recruitment, attendance, and retention of BRIDGE participants, patient interviews, and debriefing of clinician and staff views of the clinical program. Implementation metrics included program development time, workflow and scheduling logistics, and billing compliance for sustainability. Finally, patient parameters including changes in liver enzymes, FIB-4, weight, and BMI from pre- to post-BRIDGE were retrospectively analyzed.ResultsWe included 57 participants (median age 57, interquartile range (IQR) 50 – 65 years), 38 (67%) female, 38 (67%) white, and 40% had public insurance. Thirty-three (58%) participants completed all six sessions, while 43 (75%) attended at least five sessions. Patients who completed all sessions were older (median age 61 vs 53.5; p = 0.01). Gender, race/ethnicity, and insurance type were not significantly associated with missed sessions, and patients had similar rates of completion regardless of weight, BMI, or stage of liver disease. Barriers to completion included personal illness, family reasons, work commitments, or insurance issues. Prior to BRIDGE, median BMI was 31.9 (SD 29 – 36), with a median weight loss of 2 pounds (IQR -2 – 6) after BRIDGE.ConclusionThe BRIDGE telehealth SMA program was feasible, well-attended, and positively reviewed. This pilot study informs future iterations of program development and evaluation of outcome measures.

The Association between Healthy Eating Index-2015 and Serum Metabolic Parameters in Women with Gallstone Disease: A Case-Control Study.

One of the most prevalent gastrointestinal tract ailments is gallstone disease (GD). Diet has been acknowledged as a modifiable GD risk factor. The Healthy Eating Index (HEI) is a scale for evaluating the quality of diets; therefore, this study aimed to determine whether the HEI-2015 score was associated with serum metabolic parameters in women with GD. This case-control study was conducted on a sample of 75 women diagnosed with GD and 75 healthy women at the Gastroenterology and Hepatology Clinic of Shahid Beheshti University of Medical Science in Tehran, Iran. Standard laboratory methods were employed to measure the biochemical parameters. The participants' habitual dietary intake was assessed using a validated food frequency questionnaire (FFQ). The HEI-2015 score was computed for all participants. The study employed multivariate logistic regression to identify the optimal predictor of GD. The Pearson Correlation was employed to determine the correlation between the HEI-2015 and serum metabolic parameters. The study found a significant negative association between the risk of GD and serum HDL-c (OR: 0.84; 95% CI: 0.76-0.95, P=0.008). Moreover, a significant positive association was detected between HOMAIR (OR: 3.27; 95% CI: 1.16-9.19, P=0.025), and the risk of GD. The study did not find a statistically significant correlation between the HEI-2015 and serum parameters. While an association was discovered between certain serum metabolic parameters and the risk of GD, the results do not provide a significant association between serum metabolic parameters and HEI-2015 score.

The burden of significant pain in the cirrhosis population: Risk factors, analgesic use, and impact on health care utilization and clinical outcomes.

We aimed to characterize pain and analgesic use in a large contemporary cohort of patients with cirrhosis and to associate pain with unplanned health care utilization and clinical outcomes in this population. We included all patients with cirrhosis seen in UCSF hepatology clinics from 2013 to 2020. Pain severity and location were determined using documented pain scores at the initial visit; "significant pain" was defined as moderate or severe using established cutoffs. Demographic, clinical, and medication data were abstracted from electronic medical records. Associations between significant pain and our primary outcome of 1-year unplanned health care utilization (ie, emergency department visit or hospitalization) and our secondary outcomes of mortality and liver transplantation were explored in multivariable models. Among 5333 patients with cirrhosis, 32% had a nonzero pain score at their initial visit and 25% had significant (ie moderate/severe) pain. Sixty percent of patients with significant pain used ≥1 analgesic; 34% used opioids. Patients with cirrhosis with significant pain had similar Model for End-Stage Liver Disease-Sodium scores (14 vs. 13), but higher rates of decompensation (65% vs. 55%). The most common pain location was the abdomen (44%). Patients with abdominal pain, compared to pain in other locations, were more likely to have decompensation (72% vs. 56%). Significant pain was independently associated with unplanned health care utilization (adjusted odds ratio: 1.3, 95% CI: 1.1-1.5) and mortality (adjusted hazard ratio: 1.4, 95% CI: 1.2-1.6). Pain among patients with cirrhosis is often not well-controlled despite analgesic use, and significant pain is associated with unplanned health care utilization and mortality in this population. Effectively identifying and treating pain are essential in reducing costs and improving quality of life and outcomes among patients with cirrhosis.

Intelligent Liver Function Testing (iLFT): An Intelligent Laboratory Approach to Identifying Chronic Liver Disease.

The intelligent Liver Function Testing (iLFT) pathway is a novel, algorithm-based system which provides automated laboratory investigations and clinical feedback on abnormal liver function test (LFT) results from primary care. iLFT was introduced to NHS Tayside, Scotland, in August 2018 in response to vast numbers of abnormal LFTs, many of which were not appropriately investigated, coupled with rising mortality from chronic liver disease. Here, we outline the development and implementation of the iLFT pathway, considering the implications for the diagnostic laboratories, primary care services and specialist hepatology clinics. Additionally, we describe the utility, outcomes and evolution of iLFT, which was used over 11,000 times in its first three years alone. Finally, we will consider the future of iLFT and propose areas where similar 'intelligent' approaches could be used to add value to laboratory investigations.

Strategies of hepatitis C virus elimination for people who inject drugs receiving opioid agonist therapy in the era of direct‐acting antivirals

AbstractIncreased uptake of hepatitis C virus (HCV) treatment among people who inject drugs (PWID) is critical to achieve HCV elimination goals. This study attempted to observe the influence of different referral strategies among HCV‐infected PWID for direct‐acting antivirals (DAA). From January 2019 to November 2020, approximately 190 PWID regularly received opioid agonist therapies (OAT) in the drug addiction rehabilitation clinic of our institute. Among these, those with positive anti‐HCV were further referred to our hepatology clinics for HCV viremia screening and treatment. According to physician involvement, referral strategies were divided into three models including patient self‐intention referral (SR); intensive referral (IR) where patients were referred by clinicians; and fast‐intensive referral (FIR) where patients were referred by clinicians with a fast‐screening and easy‐treatment program. A total of 121 HCV‐infected PWID were enrolled and 71 (58.7%) of them received the referrals: 16 (22.5%) in the SR model, 36 (50.7%) in the IR model, and 19 (26.8%) in the FIR model. Monthly average referred patient number was 2.7 people in the SR model, 2.8 people in the IR model, and 4.8 people in the FIR model, respectively. Among the 71 referred patients, 64 (90.1%) had detectable HCV viremia with genotype distributions being genotype 1a (G1a) in 23 patients (35.9%), G1b in 10 (15.6%), G2 in 5 (7.8%), G3 in 6 (9.4%), and G6 in 20 (31.3%). Except for three patients who refused treatment, 61 patients underwent and completed DAA treatment including 35 patients for Maviret, 15 for Epclusa, 9 for Harvoni, and 2 for Zepatier. Excluding three patients who were lost to follow‐up and one becoming reinfected, 57 (93.4%) eventually achieved a sustained virologic response. Although HCV treatment uptake among PWID in this hospital‐based setting remained suboptimal, the FIR model with a quick‐to‐screen and easy‐to‐treat program was proven practicable in the hospital setting. Further innovative strategies are required to reach all HCV‐infected PWID receiving OAT.

Prevalence of Classical Extraintestinal Manifestations among Inflammatory Bowel Disease Patients in Saudi Arabia: A Single Tertiary Center Experience.

Patients with inflammatory bowel disease (IBD) may also experience extraintestinal manifestations (EIMs), which can affect various organ systems, and their occurrence is based on disease activity. To determine the prevalence of EIMs and their most common types among IBD patients from Saudi Arabia. This retrospective study included all IBD patients aged 14-80 years who visited the Gastroenterology and Hepatology clinics at King Fahad Medical City, Riyadh, between February 2017 and December 2022. The collected data included demographic characteristics, disease characteristics, EIMs, and treatment. The study included 578 IBD patients, of which 65 (11.2%) had at least one EIM, with primary sclerosing cholangitis (46.2%) and sacroiliitis (16.9%) being the most common. Patients with ulcerative colitis were more likely to have EIMs than those with Crohn's disease (15.1% vs. 9%; P = 0.026). Patients with ileocolonic (L3) Crohn's disease reported a higher prevalence of EIMs (7.5%) than those with other disease locations (P = 0.012), while in patients with ulcerative colitis, those with extensive colitis (E3) reported higher prevalence of EIMs (19.2%) (P = 0.001). Patients receiving 6 MP had a significantly high prevalence of EIMs (P = 0.014). The prevalence of extraintestinal manifestations among IBD patients in Saudi Arabia is 11.2%. These findings suggest the need for clinicians to screen for EIMs and manage them early. Further research is needed to understand the mechanisms underlying EIMs for the development of more effective treatments.

Evaluation of Circular RNA SMARCA5 as a Novel Biomarker for Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is the fourth most prevalent type of cancer in Egypt and the sixth globally. Most patients with HCC are typically diagnosed during the advanced stages of the disease due to the absence of biomarkers for early detection. Consequently, these patients miss the optimal timeframe for receiving therapy. we aimed to assess the circular RNA SMARCA5 level and SMARCA5 mRNA gene expression as a potential biomarker for early detection of HCC. The present study utilized a case-control design comprising 159 participants. Participants were selected from both inpatient and outpatient hepatology and gastroenterology clinics at the National Liver Institute Hospital, Menoufia University. They were evenly distributed among three groups: Group I: 53 control subjects, Group II: 53 HCV cirrhotic patients, and Group III: 53 HCC patients. Tumor staging was done using BCLC staging system. Each patient underwent a thorough clinical examination, radiological examination, complete history taking, and serum Alpha-fetoprotein (AFP) assessment and detection of circular RNASMARCA5 and SMARCA5mRNA gene sutilizing quantitative real-time polymerase chain reaction. Statistically substantial differences were observed in the examined groups in terms of AFP, SMARCA5, and CircSMARCA5 (P-value = 0.001, 0.001 & 0.001). CircSMARCA5 and SMARCA5mRNA were markedly down regulated in the HCC group compared to HCV cirrhotic patients and controls. ROC analysis for early HCC diagnosis demonstrated that the CircSMARCA5 area under the curve (AUC) at cut-off point 4.55 yielded a specificity of 83.8% and sensitivity of 91.7%. The AUC for AFP at a cut-off point of 515ng/ml yielded a specificity of 89.2% and a sensitivity of 91.3%. CircSMARCA5 has the potential to be a more sensitive predictor of HCC disease compared to AFP.

Diagnostic value of IgG antibody and stool antigen tests for chronic Helicobacter pylori infections in Ibb Governorate, Yemen

The stool antigen test (SAT) and the serum Helicobacter pylori (H. pylori) IgG antibody assays exhibit significant utility in the clinical diagnosis of H. pylori infection and in distinguishing between acute and chronic infections. The main objective of the current study was to identify the diagnostic value of serum H. pylori IgG antibody and SAT in the detection of H. pylori infections among chronic H. pylori-infected patients residing in Ibb Governorate, Yemen. 200 patients with H. pylori infection, confirmed through positive results in the serum immunochromatographic antibody test, were selected for H. pylori infection confirmation using serum H. pylori IgG antibodies and SAT across diverse hospitals, gastroenterology, and Hepatology clinics in Ibb Governorate. After the selection of patients, blood and stool specimens were obtained from all participants and underwent analysis via the Statistical Package for the Social Sciences (SPSS). The prevalence of H. pylori infection demonstrated variability based on the confirmatory tests, with rates of 54% for SAT and 78.5% for serum H. pylori IgG antibody, contrasting with a 100% prevalence observed in the screening serum immunochromatographic antibody test. Clinically, the study categorized H. pylori infections into four stages, whereby a significant proportion of patients (40.5%) exhibited positivity for both serum H. pylori IgG antibody and SAT, indicative of active chronic infections. The majority of positive cases only manifested serum H. pylori IgG antibody presence (chronic infections) at 38%, whereas 13.5% exclusively tested positive for SAT, corresponding to acute infections. Moreover, 88% of patients did not have either serum H. pylori IgG antibody or SAT (absence of infections) during confirmatory tests. Noteworthy is the study's approach employing multiple tests for H. pylori infection detection, focusing predominantly on chronic infections-prevailing types caused by H. pylori. The results revealed a significant association between serum levels of H. pylori IgG antibody and SAT results with the presence of diverse gastrointestinal symptoms among patients, which increased with long H. pylori infection durations.
