Clinical and patient-reported outcomes in patients with chronic hepatitis B and C and non-alcoholic fatty liver disease from real-world practices in Saudi Arabia, Turkey and Egypt

Patients with chronic liver disease (CLD) experience health-related quality of life (HRQoL) and patient-reported outcomes (PROs) impairments. We assessed and identified predictors of HRQoL and PROs in CLD patients from Saudi Arabia (SA), Turkey and Egypt. Patients enrolled in Global Liver Registry™ with chronic hepatitis B (CHB), chronic hepatitis C (CHC) and non-alcoholic fatty liver disease (NAFLD) or non-alcoholic steatohepatitis (NASH) were included. Clinical data and PRO questionnaires (FACIT-F, CLDQ and WPAI) were compared across countries. Linear regression identified PRO predictors. Of the 4014 included patients, 26.9% had CHB, 26.9% CHC and 46.1% NAFLD/NASH; 19.2% advanced fibrosis. Compared across countries, CHB patients were younger in Egypt (mean age [years] 41.2 ± 11.4 vs. 45.0 ± 10.3 SA, 46.1 ± 12.0 Turkey), most often employed in SA (64.8% vs. 53.2% Turkey) and had the lowest prevalence of obesity in Turkey (26.7% vs. 37.8% SA, 38.5% Egypt). In SA, CHB patients had lowest prevalence of fibrosis and comorbidities (all p < .01). There was a higher frequency of males with NAFLD/NASH in SA (70.0% vs. 49.6% Turkey, and 35.5% Egypt). Among NAFLD/NASH patients, CLDQ-NAFLD/NASH scores were highest in SA (mean total score: 5.3 ± 1.2 vs. 4.8 ± 1.2 Turkey, 4.1 ± 0.9 Egypt, p < .01). Independent predictors of worse PROs included younger age, female sex, advanced fibrosis, non-hepatic comorbidities and lack of regular exercise (all p < .05). Clinical presentation and PRO scores of CLD patients vary across SA, Turkey and Egypt. Impairment of HRQoL is associated with demographic factors, lack of regular exercise, advanced fibrosis and non-hepatic comorbidities.

Endoscopic Submucosal Dissection: A Safe and Effective Alternative to Surgical Intervention for Esophageal Hemangioma

BACKGROUND

Hemangiomas represent 3% of all benign esophageal tumors. Conventional esophagectomy is the standard treatment with its invasive nature and possible surgical complications. Now, less invasive techniques are used with better results. Endoscopic submucosal dissection (ESD) is one of the novel noninvasive methods used for en bloc removal of tumors. No available data about the use of ESD in removing esophageal hemangioma. Here, we studied the validity and safety of ESD as a minimally invasive procedure to remove esophageal hemangioma.

METHODS

Three patients were diagnosed with esophageal hemangioma and underwent ESD with en bloc resection. Endoscopic ultrasound (EUS) was performed before ESD to better evaluate the layer of origin and vascularity and guard against perforation. Patients were followed up postintervention to document possible complications.

RESULTS

Among the 3 studied patients, one presented with chronic abdominal pain, the second was complaining of dysphagia, and the third patient was diagnosed accidentally. Pathology reports confirmed the diagnosis of hemangiomas in all cases with no atypia and complete removal of the lesions. No complications were reported during the procedure or over the follow-up period.

CONCLUSIONS

ESD is a proper, minimally invasive method with good en bloc resection that can be used in cases of esophageal hemangiomas.

Prevalence of metabolic dysfunction-associated steatotic liver disease in the Middle East and North Africa

BACKGROUND AND AIMS

Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as nonalcoholic fatty liver disease (NAFLD), is common and closely associated with type 2 diabetes (T2D). We assessed the prevalence of NAFLD/MASLD in the general population and among patients with T2D in the Middle East and North Africa (MENA) region.

METHODS

We searched PubMed and Embase for English-language articles published between 1990 and 2023 according to PRISMA. Each country's NAFLD/MASLD prevalence in the general population and in T2D patients was predicted by using a multivariable meta regression model. Input data were extracted from our systematic review, GBD and NCD Risk Factor Collaboration. Confidence intervals were constructed by using prediction intervals with the delta method.

RESULTS

Meta-analytic pooling estimated the prevalence of NAFLD/MASLD as 39.43% in the general population and 68.71% among T2D patients. NAFLD/MASLD prevalence has increased from 35.42% (2008-2016) to 46.20% (2017-2020). Using GBD-2019 dataset, it was predicted that there are 141.51 million cases of NAFLD/MASLD in the MENA region. The highest number of NAFLD/MASLD cases were expected in Egypt (25.71 million), followed by Türkiye (23.33 million) and Iran (19.85 million). Estimated NAFLD prevalence exceeded 40% in 10 of 21 countries with the top countries being Kuwait (45.37%), Egypt (45.0%), Qatar (44.4%), and Jordan (43.3%). Furthermore, it was predicted that there are 24.96 million cases of NAFLD/MASLD with T2D in the MENA region.

CONCLUSIONS

In the MENA region, prevalence of NAFLD/MASLD is very high and growing, necessitating an urgent need for regional public policy to deal with this growing burden.

Clinical Utility of Cytokeratins for Accurate Diagnosis of Hepatocellular Carcinoma Among Hepatitis C Virus High-Risk Patients

OBJECTIVES

Hepatocellular carcinoma (HCC) is a primary malignancy of the liver and a global health problem. It is often diagnosed at advanced stage where hopeless for effective therapies. Identification of more reliable biomarkers for early detection of HCC is urgently needed. Cytokeratins are a marker of hepatic progenitor cells and act as a key player in tumor invasion. Herein, we sought to develop a novel score based on the combination of cytokeratin 18 (CK18) and cytokeratin 19 (CK19) with routine laboratory tests for accurate detection of HCC.

MATERIAL & METHODS

Serum CK18, CK 19, α-fetoprotein, albumin and platelets count were assayed in HCC patients (75), liver cirrhosis patients (55) and healthy control (20). Areas under receiving operating curve (AUCs) were calculated and used for construction on novel score. A novel score named CK-HCC = CK 19 (ng/ml)×0.001+ CK18 (ng/ml)×0.004 + AFP (U/L)×5.4 - Platelets count (×109)/L×0.003 - Albumin (g/L)×0.27-36 was developed. CK-HCC score produces AUC of 0.919 for differentiating patients with HCC from those with liver cirrhosis with sensitivity and specificity of a cut-off 1.3 (i.e., less than 1.3 the case is considered cirrhotic, whereas above 1.3 it is considered HCC.

CONCLUSION

CK-HCC score could replace AFP during screening of HCV patients and early detection of HCC.

Global survey of stigma among physicians and patients with nonalcoholic fatty liver disease

BACKGROUND & AIMS

Patients with fatty liver disease may experience stigma from the disease or comorbidities. In this cross-sectional study, we aimed to understand stigma among patients with nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH) and healthcare providers.

METHODS

Members of the Global NASH Council created two surveys about experiences/attitudes toward NAFLD and related diagnostic terms: a 68-item patient and a 41-item provider survey.

RESULTS

Surveys were completed by 1,976 patients with NAFLD across 23 countries (51% Middle East/North Africa [MENA], 19% Europe, 17% USA, 8% Southeast Asia, 5% South Asia) and 825 healthcare providers (67% gastroenterologists/hepatologists) across 25 countries (39% MENA, 28% Southeast Asia, 22% USA, 6% South Asia, 3% Europe). Of all patients, 48% ever disclosed having NAFLD/NASH to family/friends; the most commonly used term was "fatty liver" (88% at least sometimes); "metabolic disease" or "MAFLD" were rarely used (never by >84%). Regarding various perceptions of diagnostic terms by patients, there were no substantial differences between "NAFLD", "fatty liver disease (FLD)", "NASH", or "MAFLD". The most popular response was being neither comfortable nor uncomfortable with either term (56%-71%), with slightly greater discomfort with "FLD" among the US and South Asian patients (47-52% uncomfortable). Although 26% of patients reported stigma related to overweight/obesity, only 8% reported a history of stigmatization or discrimination due to NAFLD. Among providers, 38% believed that the term "fatty" was stigmatizing, while 34% believed that "nonalcoholic" was stigmatizing, more commonly in MENA (43%); 42% providers (gastroenterologists/hepatologists 45% vs. 37% other specialties, p = 0.03) believed that the name change to metabolic dysfunction-associated steatotic liver disease (or MASLD) might reduce stigma. Regarding the new nomenclature, the percentage of providers reporting "steatotic liver disease" as stigmatizing was low (14%).

CONCLUSIONS

The perception of NAFLD stigma varies among patients, providers, geographic locations and sub-specialties.

IMPACT AND IMPLICATIONS

Over the past decades, efforts have been made to change the nomenclature of nonalcoholic fatty liver disease (NAFLD) to better align with its underlying pathogenetic pathways and remove any potential stigma associated with the name. Given the paucity of data related to stigma in NAFLD, we undertook this global comprehensive survey to assess stigma in NAFLD among patients and providers from around the world. We found there is a disconnect between physicians and patients related to stigma and related nomenclature. With this knowledge, educational programs can be developed to better target stigma in NAFLD among all stakeholders and to provide a better opportunity for the new nomenclature to address the issues of stigma.

Tailored Model of Care for Patients with Metabolic Dysfunction-Associated Steatotic Liver Disease

Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as nonalcoholic fatty liver disease (NAFLD), is increasing globally, creating a growing public health concern. However, this disease is often not diagnosed, and accurate data on its epidemiology are limited in many geographical regions, making it challenging to provide proper care and implement effective national plans. To combat the increasing disease burden, screening and diagnosis must reach a significant number of high-risk subjects. Addressing MASLD as a health care challenge requires a multidisciplinary approach involving prevention, diagnosis, treatment, and care, with collaboration between multiple stakeholders in the health care system. This approach must be guided by national and global strategies, to be combined with efficient models of care developed through a bottom-up process. This review article highlights the pillars of the MASLD model of care (MoC), including screening, risk stratification, and establishing a clinical care pathway for management, in addition to discussing the impact of nomenclature change on the proposed MoC.

Artificial Intelligence in endoscopy: A future poll

Artificial Intelligence [AI] has been a trendy topic in recent years, with many developed medical applications. In gastrointestinal endoscopy, AI systems include computer-assisted detection [CADe] for lesion detection as bleedings and polyps and computer-assisted diagnosis [CADx] for optical biopsy and lesion characterization. The technology behind these systems is based on a computer algorithm that is trained for a specific function. This function could be to recognize or characterize target lesions such as colonic polyps. Moreover, AI systems can offer technical assistance to improve endoscopic performance as scope insertion guidance. Currently, we believe that such technologies still lack legal and regulatory validations as a large sector of doctors and patients have concerns. However, there is no doubt that these technologies will bring significant improvement in the endoscopic management of patients as well as save money and time.

Rare liver diseases in Egypt: Clinical and epidemiological characterization

Illnesses that afflict a tiny number of individuals are referred to as rare diseases (RDs), sometimes called orphan diseases. The local healthcare systems are constantly under financial, psychological, and medical strain due to low incidence rates, unusual presentations, flawed diagnostic standards, and a lack of treatment alternatives for these RDs. The effective management of the once widely spread viral hepatitis B and C has altered the spectrum of liver diseases in Egypt during the last several years. The detection of uncommon disorders such as autoimmune, cholestatic, and hereditary liver diseases has also been made easier by the increasing knowledge and greater accessibility of specific laboratory testing. Finally, despite Egypt's large population, there are more uncommon liver disorders than previously thought. This review article discusses the clinical and epidemiological characteristics of a few uncommon liver disorders and the information currently accessible concerning these illnesses in Egypt.

A multisociety Delphi consensus statement on new fatty liver disease nomenclature

The principal limitations of the terms NAFLD and NASH are the reliance on exclusionary confounder terms and the use of potentially stigmatising language. This study set out to determine if content experts and patient advocates were in favor of a change in nomenclature and/or definition. A modified Delphi process was led by three large pan-national liver associations. The consensus was defined a priori as a supermajority (67%) vote. An independent committee of experts external to the nomenclature process made the final recommendation on the acronym and its diagnostic criteria. A total of 236 panelists from 56 countries participated in 4 online surveys and 2 hybrid meetings. Response rates across the 4 survey rounds were 87%, 83%, 83%, and 78%, respectively. Seventy-four percent of respondents felt that the current nomenclature was sufficiently flawed to consider a name change. The terms "nonalcoholic" and "fatty" were felt to be stigmatising by 61% and 66% of respondents, respectively. Steatotic liver disease was chosen as an overarching term to encompass the various aetiologies of steatosis. The term steatohepatitis was felt to be an important pathophysiological concept that should be retained. The name chosen to replace NAFLD was metabolic dysfunction-associated steatotic liver disease. There was consensus to change the definition to include the presence of at least 1 of 5 cardiometabolic risk factors. Those with no metabolic parameters and no known cause were deemed to have cryptogenic steatotic liver disease. A new category, outside pure metabolic dysfunction-associated steatotic liver disease, termed metabolic and alcohol related/associated liver disease (MetALD), was selected to describe those with metabolic dysfunction-associated steatotic liver disease, who consume greater amounts of alcohol per week (140-350 g/wk and 210-420 g/wk for females and males, respectively). The new nomenclature and diagnostic criteria are widely supported and nonstigmatising, and can improve awareness and patient identification.

Global prevalence, cascade of care, and prophylaxis coverage of hepatitis B in 2022: a modelling study

BACKGROUND

The 2016 World Health Assembly endorsed the elimination of hepatitis B virus (HBV) infection as a public health threat by 2030; existing therapies and prophylaxis measures make such elimination feasible, even in the absence of a virological cure. We aimed to estimate the national, regional, and global prevalence of HBV in the general population and among children aged 5 years and younger, as well as the rates of diagnosis, treatment, prophylaxis, and the future burden globally.

METHODS

In this modelling study, we used a Delphi process with data from literature reviews and interviews with country experts to quantify the prevalence, diagnosis, treatment, and prevention measures for HBV infection. The PRoGReSs Model, a dynamic Markov model, was used to estimate the country, regional, and global prevalence of HBV infection in 2022, and the effects of treatment and prevention on disease burden. The future incidence of morbidity and mortality in the absence of additional interventions was also estimated at the global level.

FINDINGS

We developed models for 170 countries which resulted in an estimated global prevalence of HBV infection in 2022 of 3·2% (95% uncertainty interval 2·7-4·0), corresponding to 257·5 million (216·6-316·4) individuals positive for HBsAg. Of these individuals, 36·0 million were diagnosed, and only 6·8 million of the estimated 83·3 million eligible for treatment were on treatment. The prevalence among children aged 5 years or younger was estimated to be 0·7% (0·6-1·0), corresponding to 5·6 million (4·5-7·8) children with HBV infection. Based on the most recent data, 85% of infants received three-dose HBV vaccination before 1 year of age, 46% had received a timely birth dose of vaccine, and 14% received hepatitis B immunoglobulin along with the full vaccination regimen. 3% of mothers with a high HBV viral load received antiviral treatment to reduce mother-to-child transmission.

INTERPRETATION

As 2030 approaches, the elimination targets remain out of reach for many countries under the current frameworks. Although prevention measures have had the most success, there is a need to increase these efforts and to increase diagnosis and treatment to work towards the elimination goals.

Anesthesia in patients with chronic liver disease: An updated review

Anesthesia in chronic liver disease patients can be challenging because of the medications given or interventions performed and their effects on liver physiology. Also, the effects of liver disease on coagulation and metabolism should be considered carefully. This review focuses on anesthesia in patients with different chronic liver disease stages. A literature search was performed for Scopus and PubMed databases for articles discussing different types of anesthesia in patients with chronic liver disease, their safety, usage, and risks. The choice of anesthesia is of crucial importance. Regional anesthesia, especially neuroaxial anesthesia, may benefit some patients with liver disease, but coagulopathy should be considered. Regional anesthesia provides optimum intraoperative relaxation and analgesia that extends to the postoperative period while avoiding the side effects of intravenous anesthetics and opioids. Pharmacodynamics and pharmacokinetics of anesthetic medications must guard against complications related to overdose or decreased metabolism. The choice of anesthesia in chronic liver disease patients is crucial and could be tailored according to the degree of liver compensation and the magnitude of the surgical procedure.

Egyptian Society of Liver Cancer Recommendation Guidelines for the Management of Hepatocellular Carcinoma

Globally, hepatocellular carcinoma (HCC) is the fourth most common cause of death from cancer. The prevalence of this pathology, which has been on the rise in the last 30 years, has been predicted to continue increasing. HCC is the most common cause of cancer-related morbidity and mortality in Egypt and is also the most common cancer in males. Chronic liver diseases, including chronic hepatitis C, which is a primary health concern in Egypt, are considered major risk factors for HCC. However, HCC surveillance is recommended for patients with chronic hepatitis B virus (HBV) and liver cirrhosis; those above 40 with HBV but without cirrhosis; individuals with hepatitis D co-infection or a family history of HCC; and Nonalcoholic fatty liver disease (NAFLD) patients exhibiting significant fibrosis or cirrhosis. Several international guidelines aid physicians in the management of HCC. However, the availability and cost of diagnostic modalities and treatment options vary from one country to another. Therefore, the current guidelines aim to standardize the management of HCC in Egypt. The recommendations presented in this report represent the current management strategy at HCC treatment centers in Egypt. Recommendations were developed by an expert panel consisting of hepatologists, oncologists, gastroenterologists, surgeons, pathologists, and radiologists working under the umbrella of the Egyptian Society of Liver Cancer. The recommendations, which are based on the currently available local diagnostic aids and treatments in the country, include recommendations for future prospects.

Nonalcoholic Fatty Liver Disease-Related Hepatocellular Carcinoma: The Next Threat after Viral Hepatitis

For many years, we have faced the complications of viral hepatitis and alcohol-related liver diseases such as cirrhosis, decompensation, portal hypertension, and hepatocellular carcinoma (HCC). Recently, we have seen a dynamic change in the field of hepatology. With the significant achievements in eradicating the hepatitis C virus by direct-acting antiviral agents and the rising epidemic of obesity, diabetes mellitus, and metabolic syndrome, there is a paradigm shift in the leading cause of liver cirrhosis and cancer to nonalcoholic fatty liver disease (NAFLD). Current data highlight the rapidly rising incidence of NAFLD-related HCC worldwide and expose the unseen part of the iceberg. In this review, we aim to update knowledge about the pathogenesis of NAFLD-induced HCC, surveillance difficulties, and promising disease markers. Molecular biomarkers, for example, may become a promising cornerstone for risk-stratified surveillance, early detection, and treatment selection for NAFLD-related HCC. Physicians can offer personalized and tailor-made clinical decisions for this unique patient subgroup.

Development and validation of nonalcoholic fatty liver disease test: a simple sensitive and specific marker for early diagnosis of nonalcoholic fatty liver disease

AIM

This study aimed to develop a noninvasive test for identifying patients with nonalcoholic fatty liver disease (NAFLD) based on clinical and routine laboratory data.

METHODS

The developed model 'NAFLD test' was compared to the most commonly used NAFLD scores and then validated in three groups of NAFLD patients from five centers in Egypt, China, and Chile. Patients were divided into the discovery cohort (n = 212) and the validation study (n = 859). The ROC curve and stepwise multivariate discriminant analysis were used to develop and validate the NAFLD test and evaluate its diagnostic performance, which was then compared to other NAFLD scores.

RESULTS

Elevated C-reactive protein (CRP), cholesterol, BMI, and alanine aminotransferase (ALT) levels were significantly associated with NAFLD (P < 0.0001). NAFLD test is depicted as (-0.695 + 0.031 × BMI + 0.003 × cholesterol + 0.014 × ALT + 0.025 × CRP) to discriminate patients with NAFLD from healthy individuals. The area under the ROC curve (AUC) of the NAFLD test was 0.92 [95% confidence interval (CI): 0.88-0.96]. The NAFLD test was the most accurate diagnostic indicator of NAFLD when compared to widely used NAFLD indices. Upon validating the NAFLD test, its AUC (95% CI) for distinguishing patients with NAFLD from healthy individuals was 0.95 (0.94-0.97), 0.90 (0.87-0.93), and 0.94 (0.91-0.97) in Egyptian, Chinese, and Chilean patients with NAFLD respectively.

CONCLUSION

The NAFLD test is a new validated diagnostic biomarker that can be utilized for the early diagnosis of NAFLD with high diagnostic performance.

Hepatocellular organellar abnormalities following elimination of hepatitis C virus

BACKGROUND AND AIMS

The future development of hepatocellular carcinoma (HCC) in patients after sustained virologic response (SVR) is an important issue. The purposes of this study were to investigate pathological alterations in organelle of the liver of SVR patients and to characterize organelle abnormalities that may be related to carcinogenesis after SVR.

METHODS

The ultrastructure of liver biopsy specimens from patients with chronic hepatitis C (CHC) and SVR were compared to cell and mouse models and assessed semi-quantitatively using transmission electron microscopy.

RESULTS

Hepatocytes in patients with CHC showed abnormalities in the nucleus, mitochondria, endoplasmic reticulum, lipid droplet, and pericellular fibrosis, comparable to those seen in hepatitis C virus (HCV)-infected mice and cells. DAA treatment significantly reduced organelle abnormalities such as the nucleus, mitochondria, and lipid droplet in the hepatocytes of patients and mice after SVR, and cured cells, but it did not change dilated/degranulated endoplasmic reticulum and pericellular fibrosis in patients and mice after SVR. Further, samples from patients with a post-SVR period of >1 year had significantly larger numbers of abnormalities in the mitochondria and endoplasmic reticulum than those of <1 year. A possible cause of organelle abnormalities in patients after SVR could be oxidative stress of the endoplasmic reticulum and mitochondria associated with abnormalities of the vascular system due to fibrosis. Interestingly, abnormal endoplasmic reticulum was associated with patients with HCC for >1 year after SVR.

CONCLUSIONS

These results indicate that patients with SVR exhibit a persistent disease state and require long-term follow-up to detect early signs of carcinogenesis.

Informing a target product profile for rapid tests to identify HBV-infected pregnant women with high viral loads: a discrete choice experiment with African healthcare workers

BACKGROUND

Elimination of mother-to-child transmission of hepatitis B virus (HBV) requires infant immunoprophylaxis and antiviral prophylaxis for pregnant women with high viral loads. Since real-time polymerase chain reaction (RT-PCR), a gold standard for assessing antiviral eligibility, is neither accessible nor affordable for women living in low-income and middle-income countries (LMICs), rapid diagnostic tests (RDTs) detecting alternative HBV markers may be needed. To inform future development of the target product profile (TPP) for RDTs to identify highly viremic women, we used a discrete choice experiment (DCE) and elicited preference and trade-off of healthcare workers (HCW) in Africa between the following four attributes of fictional RDTs: price, time-to-result, diagnostic sensitivity, and specificity.

METHODS

Through an online questionnaire survey, we asked participants to indicate their preferred test from a set of two RDTs in seven choice tasks with varying levels of the four attributes. We used mixed multinomial logit models to quantify the utility gain or loss generated by each attribute. We attempted to define minimal and optimal criteria for test attributes that can satisfy ≥ 70% and ≥ 90% of HCWs, respectively, as an alternative to RT-PCR.

RESULTS

A total of 555 HCWs from 41 African countries participated. Increases in sensitivity and specificity generated significant utility and increases in cost and time-to-result generated significant disutility. The size of the coefficients for the highest attribute levels relative to the reference levels were in the following order: sensitivity (β = 3.749), cost (β = -2.550), specificity (β = 1.134), and time-to-result (β = -0.284). Doctors cared most about test sensitivity, while public health practitioners cared about cost and midwives about time-to-result. For an RDT with 95% specificity, costing 1 US$, and yielding results in 20 min, the minimally acceptable test sensitivity would be 82.5% and the optimally acceptable sensitivity would be 87.5%.

CONCLUSIONS

African HCWs would prefer an RDT with the following order of priority: higher sensitivity, lower cost, higher specificity, and shorter time-to-result. The development and optimization of RDTs that can meet the criteria are urgently needed to scale up the prevention of HBV mother-to-child transmission in LMICs.

Spontaneous vanishing of hepatocellular carcinoma: A case report of an extremely rare incident

One of the very uncommon clinical conditions is the spontaneous remission of tumors, with scarce reports around the world in various types of tumors. Spontaneous remission of hepatocellular carcinoma (HCC) is extremely rare, but it is well documented with a still unclear underlying mechanism. In this case report, we present one of those exceptional incidents of HCC regression with a trial to tackle possible explanations. Our case, which has a history of successfully treated hepatitis C virus, presented with a large infiltrative right lobar mass invading the main portal vein, with markedly elevated alpha fetoprotein (AFP). According to the applied diagnostic and treatment guidelines, the patient was scheduled for conservative management. Although he did not receive any specific treatments for his condition, the mass regressed in size with recanalization of the portal vein and normalization of AFP after 6 months of follow-up and keep the same for the following 3 years. The mechanisms by which spontaneous regression of HCC can occur are still unknown and should be furtherly investigated better to understand the behavior of such aggressive neoplastic disease.

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

BACKGROUND

Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.

METHODS

This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low-middle-income countries.

RESULTS

In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of 'single-use' consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low-middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.

CONCLUSION

This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high- and low-middle-income countries.

An international Delphi consensus statement on metabolic dysfunction-associated fatty liver disease and risk of chronic kidney disease

BACKGROUND

With the rising global prevalence of fatty liver disease related to metabolic dysfunction, the association of this common liver condition with chronic kidney disease (CKD) has become increasingly evident. In 2020, the more inclusive term metabolic dysfunction-associated fatty liver disease (MAFLD) was proposed to replace the term non-alcoholic fatty liver disease (NAFLD). The observed association between MAFLD and CKD and our understanding that CKD can be a consequence of underlying metabolic dysfunction support the notion that individuals with MAFLD are at higher risk of having and developing CKD compared with those without MAFLD. However, to date, there is no appropriate guidance on CKD in individuals with MAFLD. Furthermore, there has been little attention paid to the link between MAFLD and CKD in the Nephrology community.

METHODS AND RESULTS

Using a Delphi-based approach, a multidisciplinary panel of 50 international experts from 26 countries reached a consensus on some of the open research questions regarding the link between MAFLD and CKD.

CONCLUSIONS

This Delphi-based consensus statement provided guidance on the epidemiology, mechanisms, management and treatment of MAFLD and CKD, as well as the relationship between the severity of MAFLD and risk of CKD, which establish a framework for the early prevention and management of these two common and interconnected diseases.

Nonalcoholic Fatty Liver Disease in Asia, Africa, and Middle East Region

Non-alcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease worldwide. The global prevalence of the disease varies according to the geographical region. Despite having distinct models for the western patterns of NAFLD, Africa, Asia, and the Middle East regions exhibited varying prevalence rates of NAFLD. The disease burden is anticipated to significantly increase in these areas. Furthermore, with an increase in NAFLD risk factors in these regions, the disease burden is expected to rise even more. Policies at the regional and international levels are required to address such growing burden of NAFLD consequences.

Evaluation of GALAD Score in Diagnosis and Follow-up of Hepatocellular Carcinoma after Local Ablative Therapy

BACKGROUND AND AIMS

Strategies for detection of early hepatocellular carcinoma (HCC) are still limited. The GALAD score is a serum biomarker-based model designed to predict the probability of having HCC. We aimed to assess the ability of GALAD score to diagnose early HCC and its validity to follow patients after local ablation therapy.

METHODS

This multicenter prospective study included 108 patients in two groups, 58 HCC patients (67 focal lesions) with local ablative therapy (study group), and a control group of 50 patients with liver cirrhosis. The GALAD scores of the study and control groups, and of the HCC patients before and after ablative therapy were compared.

RESULTS

Most patients were men (74.1% in study group and 76% in controls) with hepatitis C virus infection (98.30% in the study group, and 94% in controls). GALAD scores were significantly higher in HCC patients than in those with benign cirrhosis (2.65 vs. -0.37, p=0.001). Ablative therapy was successful in 94.4% of focal lesions <2 cm, and in 86.10% of 2-5 cm lesions. The GALAD score was also significantly lower at 1 month after ablation in patients with well-ablated tumors (2.19 vs. 0.98, p=0.001). The best cutoff values of GALAD score for diagnosis of early HCC, and for prediction of well ablation of HCC were 0.74 and ≤3.31 (areas under the curve of 0.92 and 0.75, sensitivities of 84.48% and 76.19%, specificities of 89.13% and 83.33%, positive predictive values of 90.74% and 94.1%, and negative predictive values of 82% and 35.7% respectively).

CONCLUSION

The GALAD score was effective for the diagnosis of early HCC and for follow-up after ablative therapy.

A randomized controlled trial of SOF/VEL/VOX with or without ribavirin for retreatment of chronic hepatitis C

BACKGROUND & AIMS

The combination of sofosbuvir, velpatasvir and voxilaprevir (SOF/VEL/VOX) is recommended retreatment for patients with hepatitis C virus (HCV) infection who failed previous direct-acting antiviral (DAA) treatment. However, whether ribavirin further increases the therapeutic efficacy of SOF/VEL/VOX retreatment remains unclear. We aimed to test this hypothesis by a randomized controlled trial.

METHODS

We randomly assigned 315 patients with DAA treatment failure from 5 Egyptian sites into two groups. Group A (n=158) received SOF/VEL/VOX for 12 weeks, and group B (n=157) received SOF/VEL/VOX + weight-based ribavirin for 12 weeks. Therapeutic efficacy was defined as SVR12 (undetectable HCV RNA 12 weeks after treatment completion). Safety and tolerability were evaluated by monitoring treatment-related adverse events (AEs) and laboratory abnormalities.

RESULTS

Seventeen patients in each group were lost to follow-up. SVR12 rates by intention-to-treat (ITT) were 87.3% (138/158), and by per-protocol analysis, 97.8% (138/141) in group A; and 87.9% (138/157) and 98.5% (138/140) in group B (p=NS for ITT and PP). Males comprised 53.9% of group A, and 57.1% in group B (p=0.58), with mean ages of 51.8 and 47.3 years in group A and B, respectively. Both regimens were well-tolerated, with no deaths and only one serious AE (anemia) in group B requiring ribavirin discontinuation. Fifty-five patients in group A vs. 77 in group B experienced any adverse events (p=0.002).

CONCLUSION

This randomized controlled trial showed equal, high efficacy of both regiments in retreating previous DAA failures, although ribavirin was associated with more adverse events. Therefore SOF/VEL/VOX monotherapy should be the preferred retreatment strategy.

IMPACT AND IMPLICATIONS

HCV treatment guidelines recommend retreating DAA treatment failures with the combination of sofosbuvir, velpatasvir and voxilaprevir (SOF/VEL/VOX) for 12 weeks. However, whether ribavirin exerts an additional/synergistic effect remains unclear. The present study confirmed that SOF/VEL/VOX without ribavirin is the best regimen for retreating DAA treatment failures, and thus will help clinicians caring for patients who are not cured with a first course of DAA therapy.

Diagnosis, treatment protocols, and outcomes of liver transplant recipients infected with COVID-19

Several cases of fatal pneumonia during November 2019 were linked initially to severe acute respiratory syndrome coronavirus 2, which the World Health Organization later designated as coronavirus disease 2019 (COVID-19). The World Health Organization declared COVID-19 as a pandemic on March 11, 2020. In the general population, COVID-19 severity can range from asymptomatic/mild symptoms to seriously ill. Its mortality rate could be as high as 49%. The Centers for Disease Control and Prevention have acknowledged that people with specific underlying medical conditions, among those who need immunosuppression after solid organ transplantation (SOT), are at an increased risk of developing severe illness from COVID-19. Liver transplantation is the second most prevalent SOT globally. Due to their immunosuppressed state, liver transplant (LT) recipients are more susceptible to serious infections. Therefore, comorbidities and prolonged immunosuppression among SOT recipients enhance the likelihood of severe COVID-19. It is crucial to comprehend the clinical picture, immunosuppressive management, prognosis, and prophylaxis of COVID-19 infection because it may pose a danger to transplant recipients. This review described the clinical and laboratory findings of COVID-19 in LT recipients and the risk factors for severe disease in this population group. In the following sections, we discussed current COVID-19 therapy choices, reviewed standard practice in modifying immunosuppressant regimens, and outlined the safety and efficacy of currently licensed drugs for inpatient and outpatient management. Additionally, we explored the clinical outcomes of COVID-19 in LT recipients and mentioned the efficacy and safety of vaccination use.

Clinical and patient-reported outcome profile of patients with hepatitis B viral infection from the Global Liver Registry™

Chronic hepatitis B (CHB) infection is one of the most common causes of cirrhosis and liver cancer worldwide. Our aim was to assess clinical and patient-reported outcome (PRO) profile of CHB patients from different regions of the world using the Global Liver Registry. The CHB patients seen in real-world practices are being enrolled in the Global Liver Registry. Clinical and PRO (FACIT-F, CLDQ, WPAI) data were collected and compared to baseline data from CHB controls from clinical trials. The study included 1818 HBV subjects (48 ± 13 years, 58% male, 14% advanced fibrosis, 7% cirrhosis) from 15 countries in 6/7 Global Burden of Disease super-regions. The rates of advanced fibrosis varied (3-24%). The lowest PRO scores across multiple domains were in HBV subjects from the Middle East/North Africa (MENA), the highest - Southeast/East and South Asia. Subjects with advanced fibrosis had PRO impairment in 3 CLDQ domains, Activity of WPAI (p < 0.05). HBV subjects with superimposed fatty liver had more PRO impairments. In multivariate analysis adjusted for location, predictors of PRO impairment in CHB included female sex, advanced fibrosis, and non-hepatic comorbidities (p < 0.05). In comparison to Global Liver Registry patients, 242 controls from clinical trials had better PRO scores (Abdominal, Emotional, and Systemic scores of CLDQ, all domains of WPAI) (p < 0.05). In multivariate analysis with adjustment for location and clinicodemographic parameters, the associations of PROs with the enrollment setting (real-life Global Liver Registry vs. clinical trials) were no longer significant (all p > 0.10). The clinico-demographic portrait of CHB patients varies across regions of the world and enrollment settings. Advanced fibrosis and non-hepatic comorbidities are independently associated with PRO impairment in CHB patients.

Gender differences in prevalence of hepatitis C virus infection in Egypt: a systematic review and meta-analysis

Egypt is the country with the highest known hepatitis C virus (HCV) prevalence worldwide. The origin of gender differences in HCV prevalence is not usually well understood. This systematic review and meta-analysis aimed to review and evaluate the gender differences in HCV infection rates amongst Egyptians. Such data would be important to support prevention and control programs aiming to minimize HCV-related morbidity and mortality. PubMed, Scopus, and Web of Science (WOS) were searched for relevant articles published from 1st January 2011 to 13th December 2021, using the search terms (HCV OR "hepatitis C" OR hepacivirus) AND (prevalence OR seroprevalence OR epidemiology OR incidence OR magnitude). At first, retrieved articles were screened, and then relevant data were extracted and analyzed. Descriptive statistics were used for data analysis. Out of 616 studies from databases, only 30 were included after the full-text screening, with 193,621 included participants: 97,597 male and 96,024 female. The overall seroprevalence of HCV antibodies in all included studies was 0.02 (CI - 0.23 to 0.28), with no significant difference between males and females. However, HCV RNA positivity was significantly more prevalent in males than females in adults and the general population (after excluding high-risk groups). In children, no statistically significant differences between males and females were found in the seroprevalence of HCV antibodies nor in the prevalence of PCR positivity. HCV RNA positivity is significantly higher in males than females in adults, while there are no gender differences in children.

Hepatocellular carcinoma and hepatitis C virus treatments: The bold and the beautiful

The occurrence of hepatocellular carcinoma (HCC) is one of the most serious complications of hepatitis C virus (HCV) infection. Recently, effective antiviral medications have made sustained viral response (SVR) or cure a realistic therapeutic goal for most chronic HCV patients. Given HCV's tumorigenic propensity, it is not surprising that achieving SVR is helpful in preventing HCC. This review briefly summarizes and discusses the existing evidence on the relationship between hepatic carcinogenesis and viral eradication by antivirals, which is mainly divided into interferon-based and direct-acting antivirals (DAAs) based therapy. DAAs have changed the treatment landscape of chronic HCV, reaching high rates of SVR even in patients with advanced cirrhosis, with few contraindications and little side effects. Although some early reports suggested that DAA treatment increased the chance of HCC occurrence, more subsequent observational studies have refuted this theory. The probability of HCC recurrence after HCV eradication appears to be decreasing over time following SVR. Despite virological suppression/cure, individuals with liver cirrhosis are still at risk of HCC and should be monitored. There is a considerable need for markers/scores to predict the long-term risk of HCC in patients with HCV-related liver disease who attain SVR with direct-acting antivirals.

Prospective Comparison of Hepatocellular Carcinoma Behavior and Survival of Patients who Did or Did not Receive HCV Direct-Acting Antivirals

BACKGROUND & AIMS

The safety and efficacy of hepatitis C (HCV) direct-acting antivirals (DAAs) have been established in several real-world trials; however, some reports have claimed an association between DAAs and hepatocellular carcinoma (HCC) occurrence or aggressive behavior. We aimed to prospectively examine differences in de-novo HCC tumor behavior and overall survival (OS) in DAAs-treated versus HCV-untreated patients as measured by BCLC progression during a two-year follow-up period.

METHODS

This multicenter cohort study recruited 523 patients with de-novo HCV-related HCC. After exclusion criteria were applied, 353 patients were placed into; Group 1, including 236 patients without a history of DAAs therapy, and Group 2 including 117 patients with de-novo HCC developed after receiving DAAs. Patients were then stratified in each group according to BCLC staging (Liver, 2018). All patients received standard of care management and were followed until death or a maximum of 2 years.

RESULTS

No statistically significant differences were observed between the two groups regarding tumor characteristics (number and size of lesions) and criteria for aggressiveness upon presentation. Among all BCLC stages, DAAs treated patients showed significantly lower baseline Fib4 values than DAA untreated patients in BCLC-0 stage (4.1 vs 7.7, p 0.019). No statistically significant differences were evident in HCC progression in the different BCLC stages at 12 and 24 months follow up periods (p 0.0718 and 0.279 respectively). Significantly better survival was recorded in Group 1 compared to Group 2 patients for BCLC stages C and D (p = 0.003 and 0.01, respectively).

CONCLUSION

HCC may develop at an earlier stage of liver disease after DAAs therapy. No defensive role was found for DAAs treatment in delaying HCC progression that occurs after viral eradication.<br />.

Non-pulmonary involvement in COVID-19: A systemic disease rather than a pure respiratory infection

During the early phase of the coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), diagnosis was difficult due to the diversity in symptoms and imaging findings and the variability of disease presentation. Pulmonary manifestations are reportedly the main clinical presentations of COVID-19 patients. Scientists are working hard on a myriad of clinical, epidemiological, and biological aspects to better understand SARS-CoV-2 infection, aiming to mitigate the ongoing disaster. Many reports have documented the involvement of various body systems and organs apart from the respiratory tract including the gastrointestinal, liver, immune system, renal, and neurological systems. Such involvement will result in diverse presentations related to effects on these systems. Other presentations such as coagulation defects and cutaneous manifestation may also occur. Patients with specific comorbidities including obesity, diabetes, and hypertension have increased morbidity and mortality risks with COVID-19.

Changes in Presentation, Treatment, and Survival of Patients with Hepatocellular Carcinoma in Damietta, Egypt, 2007-2019: A Retrospective Monocentric Cohort Study

Introduction

We aimed to assess temporal changes in the presentation and survival of patients with hepatocellular carcinoma (HCC) in the northern Egypt region, one of the regions reporting the highest incidence of the disease globally.

Methods

We conducted a monocentric retrospective study. Patients presenting at the Damietta Oncology referral center between 2007 and 2019 with a diagnosed HCC were eligible. Individual, clinical and tumor characteristics at HCC diagnosis, including the Barcelona Clinic Liver Cancer (BCLC) staging, were retrieved from medical files and patients' final vital status was ascertained by combining various data sources. Patients were divided into 2 groups based on diagnosis period: pre- and post-2014. Survival was analysed based on Kaplan-Meier curves and differences in restricted mean survival time (RMST).

Results

Data from 5097 patients (among 5210 eligible, 97.8%) were analyzed. We observed a significant trend toward HCC diagnosed at earlier stage in the post- vs pre-2014 period (BCLC stage 0/A or B: 37.2% vs 27.1%, p<10^-3). Overall patient's survival after the HCC diagnosis was poor, with a median of 8.1 months. The BCLC staging system performed well in predicting survival. Despite a trend toward HCC diagnosed at earlier stages, we did not observe a significant improvement in survival over time. Overall, treatments offered in this medical center were in line with international guidelines, and 16.1% of the patients who received a curative treatment had an improved survival (30.7 months in median). However, HCC recurrence was frequent among patients cured for HCC, with a median time to recurrence of 22 months.

Discussion

Overall survival after HCC diagnosis in Egypt remains poor but is significantly improved by curative therapy. Despite a trend toward earlier diagnosis of HCC, we did not observe a general improvement in survival over time, which remains to be clearly understood.

Incidence of incidental positron emission tomography and computed tomography signs of COVID-19 in asymptomatic cancer patients in Egypt

Background

COVID-19 was first reported in Egypt on 14 February 2020 and continues to be a major threat to public health.

Aims

We studied the incidence of incidental positron emission tomography/computed tomography (PET/CT) signs of COVID-19 in asymptomatic cancer patients and compared this with the number of reported COVID-19 cases during the same period.

Methods

We included all cancer patients who underwent PET/CT at Misr Radiology Center, Cairo, between 2 May and 7 August 2020.

Results

There were 479 patients who underwent PET/CT primarily for follow-up, and 66 (13.78%) of them showed radiological signs of COVID-19, with the peak incidence in weeks 7-8 of the study. This coincided and strongly correlated with the peak incidence of COVID-19 in Egypt (Pearson's correlation coefficient test = 0.943).

Conclusion

The incidence of incidental PET/CT signs of COVID-19 was in accordance with the officially reported incidence of COVID-19 in Egypt between 2 May and 7 August 2020. These results could be helpful for implementing and adjusting public health and social measures during the COVID-19 pandemic.

Wilson’s disease clinic at the Assiut Liver Center in Egypt: a real well-established step on the way

Wilson’s disease (WD) is a rare genetic disorder of copper metabolism that results in dysfunction of copper excretion into bile leading to its accumulation in the liver, brain, cornea, and kidney. Only a few epidemiological studies about WD have been carried out, with limited available data about the disease. The most common liver disease in Egypt is viral hepatitis, which masks other liver diseases, especially in adults. This review describes the establishment of the first specialized WD clinic in the Assiut Liver Center, Upper Egypt. This multidisciplinary clinic comprises stakeholders working in WD management from different specialties, including hepatologists, pediatric hepatologists, neuropsychiatrists, dieticians, radiologists, pathologists, and ophthalmologists. Over 2 years since the launch of the WD clinic in February 2020, a total of 64 WD suspected cases were referred to our center. The WD clinic at the Assiut Liver Center is a step to provide an integrated service for neglected diseases like WD. Besides the provided integrated services for WD patients, a family screening program is applied with satisfying results.

MAFLD: A quick fact check

Metabolic (dysfunction)-associated fatty liver disease has taken importance during the last two years, given the new criteria for diagnosis compared to the previous criteria used to define non-alcoholic fatty liver disease. Multiple studies have also shown that this definition better adjusts to the pathogenesis and patient characteristics with fatty liver.

Estimating the risk of incident SARS-CoV-2 infection among healthcare workers in quarantine hospitals: the Egyptian example

In response to the COVID-19 epidemic, Egypt established a unique care model based on quarantine hospitals where only externally-referred confirmed COVID-19 patients were admitted, and healthcare workers resided continuously over 1- to 2-week working shifts. Using a mathematical model accounting for the false-negative rates of RT-PCR tests, we computed the incidence rate of SARS-CoV-2 infection among HCWs, while unveiling the proportion of infections remaining undiagnosed despite routine testing. We relied on longitudinal data, including results of routine RT-PCR tests, collected within three Egyptian quarantine hospitals. We estimated an incidence rate (per 100 person-day, PD) of 1.05 (95% CrI 0.58-1.65) at Hospital 1, 1.92 (95% CrI 0.93-3.28) at Hospital 2 and 7.62 (95% CrI 3.47-13.70) at Hospital 3. We found that the risk for an HCW to be infected during a working shift lay within the range of risk levels previously documented in standard healthcare settings for Hospitals 1-2, whereas it was > threefold higher for Hospital 3. This large variation suggests that HCWs from quarantine hospitals may face a high occupational risk of infection, but that, with sufficient infection control measures, this risk can be brought down to levels similar to those observed in standard healthcare settings.

The art of managing hepatitis C virus in special population groups: a paradigm shift

The first direct-acting antiviral (DAA) medications were approved for the treatment of chronic hepatitis C virus (HCV) in 2011. Later, the appearance of novel DAAs had revolutionized the landscape of HCV treatment whose early treatment options were limited to interferon (IFN) either alone or in combinations. This review discusses the paradigm shift in legibility for treating different groups of patients with HCV after the introduction of DAAs, along with the consequent changes in treatment guidelines. IFN-based therapy was the firstly used for treating chronic HCV. Unfortunately, it exhibited many pitfalls, such as low efficacy in some patients and unsuitability for usage in lots of patients with some specific conditions, which could be comorbidities such as autoimmune thyroiditis, or liver related as in decompensated cirrhosis. Furthermore, IFN failed to treat all the extrahepatic manifestations of HCV. Nowadays, the breakthroughs brought by DAAs have benefited the patients and enabled the treatment of those who could not be treated or did not usually respond well to IFN. DAAs achieve a high success rate of HCV eradication in addition to avoiding unfavorable harms and, sometimes, adverse effects related to the previously used PEGylated IFN regimens.

Gastrointestinal involvement in systemic sclerosis: An updated review

The gastrointestinal tract (GI) is the second most affected organ system in individuals suffering from systemic/localized scleroderma (SSc) or localized scleroderma. SSc can affect any part of the GI, between the oral cavity and anorectum. The annual incidence of SSc in the United States is estimated to be 19.3 cases per million adults, with the highest incidence reported in people aged 44 to 55. Females are 5 times more likely than males to suffer from SSc. Morbidity and mortality rates associated with SSc are predominantly elevated among patients with GI manifestations. Esophageal and intestinal manifestations impact 90% and 40% to 70% of patients with systemic scleroderma, respectively. SSc patients are known to suffer from small bowel hypomotility and small intestinal bacterial overgrowth, which cause malabsorption and malnutrition, ultimately contributing to the 50% mortality rate. Fecal incontinence is a common symptom of SSc that can lead to depression. SSc patients may suffer from gastrointestinal complications that can negatively impact their quality of life on a daily basis. Multidisciplinary approaches are necessary for systematically managing gastrointestinal complications associated with SSc. A prospective study should focus on developing targeted therapies to improve recovery patterns and prognosis in cases of SSc. This article summarizes the epidemiology, commonly reported clinical manifestations, complications, and available treatments for treating GI pathology in SSc patients.

Severe impairment of patient-reported outcomes in patients with chronic hepatitis C virus infection seen in real-world practices across the world: Data from the global liver registry

Cure of chronic hepatitis C (CHC) can lead to improvement of health-related quality of life and other patient-reported outcomes (PROs). While extensive PRO data for CHC patients who were enrolled in clinical trials are available, similar data for patients seen in real-world practices are scarce. Our aim was to assess PROs of CHC patients enrolled from real-world practices from different regions and to compare them with those enrolled in clinical trials. CHC patients seen in clinical practices and not receiving treatment were enrolled in the Global Liver Registry (GLR). Clinical and PRO (FACIT-F, CLDQ-HCV, WPAI) data were collected and compared with the baseline data from CHC patients enrolled in clinical trials. N = 12,171 CHC patients were included (GLR n = 3146, clinical trial subjects n = 9025). Patients were from 30 countries from 6 out of 7 Global Burden of Disease (GBD) super-regions. Compared with clinical trial enrollees, patients from GLR were less commonly enrolled from High-Income GBD super-region, older, more commonly female, less employed, had more type 2 diabetes, anxiety and clinically overt fatigue but less cirrhosis (all p < 0.001). Out of 15 PRO domain and summary scores, 12 were lower in GLR patients than in subjects enrolled in clinical trials (p < 0.001). In multiple regression models, anxiety, depression, and fatigue were associated with significant PRO impairment in CHC patients (p < 0.05). After adjustment for the clinico-demographic confounders, the association of PRO scores of CHC patients with enrolment settings was no longer significant (all p > 0.05). In conclusion, hepatitis C patients seen in the real-world practices have PRO impairment driven by fatigue and psychiatric comorbidities.

miR-516a-3P, a potential circulating biomarker in hepatocellular carcinoma, correlated with rs738409 polymorphism in PNPLA3

Aim: The aim was to investigate the expression profile of miR-516a-3P and its correlation with the PNPLA3 rs738409 polymorphism in Egyptian hepatitis C virus (HCV) and hepatocellular carcinoma (HCC) patients. Materials & methods: miR-516a-3P was quantified and rs738409 was genotyped by quantitative reverse transcription PCR. Results: miR-516a-3P was significantly upregulated in HCC patients compared with HCV patients (p = 0.001). Receiver operating characteristic curve analysis confirmed that miR-516a-3P discriminates HCC from HCV (p = 0.001). A significant (p = 0.015) correlation between miR-516a-3p level and PNPLA3 rs738409 genotypes was recorded in HCV patients, yet it was not recorded in either healthy individuals or HCC patients. miR-516a-3p level was significantly (p = 0.001) higher in HCV patients carrying the rs738409 GG genotype than in those carrying the CC genotype. Conclusion: miR-516a-3P is a potential biomarker in HCC. PNPLA3 rs738409 GG carriers affect miR-516a-3P expression in HCV, and this may highlight a new mechanism in liver disease.

Hemostatic system and COVID-19 crosstalk: A review of the available evidence

Since the discovery of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its resultant coronavirus disease 2019 (COVID-19) pandemic, respiratory manifestations have been the mainstay of clinical diagnosis, laboratory evaluations, and radiological investigations. As time passed, other pathological aspects of SARS-CoV-2 have been revealed. Various hemostatic abnormalities have been reported since the rise of the pandemic, which was sometimes superficial, transient, or fatal. Mild thrombocytopenia, thrombocytosis, venous, arterial thromboembolism, and disseminated intravascular coagulation are among the many hemostatic events associated with COVID-19. Venous thromboembolism necessitating therapeutic doses of anticoagulants is more frequently seen in severe cases of COVID-19, especially in patients admitted to intensive care units. Hemorrhagic complications rarely arise in COVID-19 patients either due to a hemostatic imbalance resulting from severe disease or as a complication of over anticoagulation. Although the pathogenesis of coagulation disturbance in SARS-CoV-2 infection is not yet understood, professional societies recommend prophylactic antithrombotic therapy in severe cases, especially in the presence of abnormal coagulation indices. The review article discusses the various available evidence on coagulation disorders, management strategies, outcomes, and prognosis associated with COVID-19 coagulopathy, which raises awareness about the importance of anticoagulation therapy for COVID-19 patients to guard against possible thromboembolic events.
