Clinical and endoscopic characteristics of patients undergoing gastrointestinal endoscopic procedures in Egypt: a nationwide multicenter study.

BACKGROUND: Egypt faces a significant public health burden due to chronic liver diseases (CLD) and peptic ulcer disease. CLD, primarily caused by Hepatitis C virus (HCV) infection, affects over 2.9% of the population nationwide, with regional variations. Steatotic liver disease is rapidly emerging as a significant contributor to CLD, especially in urban areas. Acid-related disorders are another widespread condition that can significantly impact the quality of life. These factors and others significantly influence the indications and findings of gastrointestinal endoscopic procedures performed in Egypt. AIM: We aimed to evaluate the clinico-demographic data, indications, and endoscopic findings in Egyptian patients undergoing gastrointestinal endoscopic procedures in various regions of Egypt. METHODS: This study employed a retrospective multicenter cross-sectional design. Data was collected from patients referred for gastrointestinal endoscopy across 15 tertiary gastrointestinal endoscopy units in various governorates throughout Egypt. RESULTS: 5910 patients aged 38-63 were enrolled in the study; 75% underwent esophagogastroduodenoscopy (EGD), while 25% underwent a colonoscopy. In all studied patients, the most frequent indications for EGD were dyspepsia (19.5%), followed by hematemesis (19.06%), and melena (17.07%). The final EGD diagnoses for the recruited patients were portal hypertension-related sequelae (60.3%), followed by acid-related diseases (55%), while 10.44% of patients had a normally apparent endoscopy. Male gender, old age, and the presence of chronic liver diseases were more common in patients from upper than lower Egypt governorates. Hematochezia (38.11%) was the most reported indication for colonoscopy, followed by anemia of unknown origin (25.11%). IBD and hemorrhoids (22.34% and 21.86%, respectively) were the most prevalent diagnoses among studied patients, while normal colonoscopy findings were encountered in 18.21% of them. CONCLUSION: This is the largest study describing the situation of endoscopic procedures in Egypt. our study highlights the significant impact of regional variations in disease burden on the utilization and outcomes of GI endoscopy in Egypt. The high prevalence of chronic liver disease is reflected in the EGD findings, while the colonoscopy results suggest a potential need for increased awareness of colorectal diseases.

Hepatitis B Virus Infection in Eastern Libya: Current Efforts for Overcoming Regional Barriers for Its Elimination.

Approximately 2.2% of Libyans have chronic hepatitis B (CHB) and are at the highest risk of developing end-stage disease complications. Several resource-limited countries, including Libya, may be far from achieving the WHO goal of hepatitis B elimination by 2030 as a result of several testing and linkage to care (LTC) barriers. In Libya, data about the current HBV infection situation is scarce. Therefore, our study aimed to evaluate the trends of HBV in eastern Libya, Tobruk region, and try to identify the region-specific gaps and barriers that could potentially delay the WHO goal of HBV elimination. An eighteen-year retrospective review of records of the main district medical center in the region was done to estimate the trends of HBV infection and qualitative interviews with the clinical staff of the CHB registry in the region were conducted to investigate the current status of HBV management. Out of 392,952 records, 371 (0.09%) HBV-positive were recorded and declining trends of the infection were noticed over the study period. Until late 2019, there was no linkage to care or follow-up for people with HBV infection. However, a CHB registry was established in late 2019 to manage HBV infections in the region, yet there are several barriers such as the lack of diagnostic infrastructure for liver function assessment and antiviral treatment. Despite the significant decline observed in the occurrence of HBV infection and introduction of important HBV management steps such as establishment of the CHB registry, there are still several barriers that could delay the elimination of the infection.

Prognosis of spontaneous bacterial peritonitis in patients with hepatocellular carcinoma.

BACKGROUND: Hepatocellular carcinoma (HCC) is the fourth leading cause of death from cancer worldwide. Spontaneous bacterial peritonitis (SBP) is associated with poor prognosis. This study aimed to evaluate risk factors, differences in clinical characteristics and prognosis of SBP in patients with HCC in comparison with non-HCC patients. METHODS: This study was conducted on patients with cirrhosis who were admitted to hospital with SBP. The patients were divided into two groups: SBP group with HCC (n = 150) and SBP group without HCC (n = 250). RESULTS: Men and women accounted for 72% and 28% (n = 108 and 42, respectively) of the population in SBP group with HCC with mean age 55.8 ± 13.1 years. They accounted for 68.4% and 31.6% (n = 171 and 79, respectively) in the SBP group without HCC with mean age 56.8 ± 10.5 years. In-hospital mortality was 25.3% in the SBP group with HCC and 18.8% in SBP group without HCC. Gastrointestinal bleeding was the most common cause of death in both groups. No significant difference was observed in patient outcomes between the two studied groups. The deceased patients had significantly higher levels of leukocytes and neutrophils in ascitic fluid as well as a higher frequency of positive culture results than in patients who survived (p < 0.001). However, there was no significant difference in protein level in ascitic fluid or causative organism between patients who survived and those who died (p = 0.63 and 0.19, respectively). CONCLUSIONS: Prognosis of SBP in patients with HCC seemed similar to that in patients without HCC.

A multicentric and nationwide predictive study role of T cell sub-population in the prevalence and prognosis of cryoglobulinemia among genotype 4 chronic hepatitis C patients.

The infection caused by the hepatitis C virus (HCV) is a significant global health concern. The prevailing genotype of HCV in Egypt is 4a, commonly referred to as GT-4a. A significant proportion exceeding 50% of patients infected with HCV experience extrahepatic manifestations (EHMs), encompassing a diverse range of clinical presentations. These manifestations, including essential mixed cryoglobulinemia (MC), can serve as initial and solitary indicators of the disease. The complete understanding of the pathogenesis of EHM remains unclear, with autoimmune phenomena being recognized as the primary causative factor. In this study, we examined the predictive significance of T-cell subpopulations in relation to the occurrence and prognosis of cryoglobulinemia in HCV patients. A total of 450 CHC genotype four treatment naïve patients were enrolled in this analytic cross-sectional study after thorough clinical, laboratory, and radiological examinations. All patients underwent laboratory investigations, including testing for cryoglobulin antibodies and measurements of CD4 and CD8 levels; two groups were described according to their test results: Group 1 consists of patients who have tested positive for cryoglobulin antibodies and Group 2 consists of patients who have tested negative for cryoglobulin antibodies. The exclusion criteria encompassed individuals with HIV infection or chronic HBV infection. Additionally, pelvi-abdominal ultrasonography was performed. Our study included 450 treatment naïve CHC patients (59% male, mean age 50.8 years). The patients were categorized according to their cryoglobulin antibodys test results into two groups: group A, CHC patients with cryoglobulin antibodies (Abs) negative (364 patients), and group B, CHC patients with cryoglobulin Ab positive (86 patients). Group B demonstrated a higher average age, elevated international normalized ratio, more prolonged duration of HCV infection, lower albumin, higher alanine aminotransferase, higher aspartate aminotransferase, higher bilirubin, lower CD8, lower CD4, and lower CD4:CD8 ratio. In contrast, 27 out of 86 (31.40%) patients in group B had symptoms; 85.8% had purpura and arthralgia, 74.3% had paresthesias, 86.7% had weakness, and 12.2% had non-Hodgkin's lymphoma. The levels of CD4 and CD8 were found to be decreased in chronic HCV patients with MC. T-cell subpopulation serves as a reliable indicator for assessing the prevalence and prognosis of MC in individuals with genotype 4 chronic hepatitis C. However, additional research is needed to further understand the development and spread of various emerging infectious diseases. Nevertheless, it is noteworthy that a critical threshold may exist beyond which EHM reaches a point of no return.

Levofloxacin+Tetracycline Quadruple Regimen for Eradication of Helicobacter pylori: A Multicenter Multinational Randomized Controlled Trial.

Background: The ideal combination regimen for Helicobacter pylori (HP) eradication has not yet been determined and the success rate of HP eradication has been extensively reduced worldwide due to increasing antibiotic resistance. So this multinational multi-center randomized controlled trial was designed to evaluate the efficacy of tetracycline +levofloxacin for HP eradication. Methods: During a 6-month period, all of the cases with HP infection in eight referral tertiary centers of three countries were included and randomly allocated to receive either tetracycline + levofloxacin or clarithromycin plus amoxicillin quadruple regimen for two weeks. For all of the participants, pantoprazole was continued for 4 more weeks and after one to two weeks of off-therapy, they underwent urea breath test C13 to prove eradication. Results: Overall 788 patients were included (358 male (45.4%), average age 44.2 years). They were diagnosed as having non-ulcer dyspepsia (516 cases, 65.5%), peptic ulcer disease (PUD) (234 cases, 29.69%), and intestinal metaplasia (38 cases, 4.8%). Racially 63.1% were Caucasian, 14.5% Arab, 15.6% African, and 6.1% Asian. The participants were randomly allocated to groups A and B to receive either tetracycline + levofloxacin or clarithromycin. Among groups A and B in intention to treat (ITT) and per protocol (PP) analysis, 75.2% & 82.1% (285 cases) and 67.5% & 70.1% (276 cases) of participants achieved eradication, respectively (P = 0.0001). The complete compliance rate in groups A and B were 84.4% and 83.6%, respectively. During the study, 33.5% of the participants in group A (127 cases) reported side effects while the complication rate among group B was 27.9% (114 cases, P = 0.041). The most common complaints among groups A and B were nausea and vomiting (12.6% & 9.3%) and abdominal pain (4.48% & 2.68%), respectively. The rate of severe complications that caused discontinuation of medication in groups A and B were 2.1% and 1.46%, respectively (P = 679). In subgroup analysis, the eradication rates of tetracycline+levofloxacin among patients with non-ulcer dyspepsia, PUD, and intestinal metaplasia were 79.4%, 88.1%, and 73.9%, respectively. These figures in group B (clarithromycin base) were 71.3%, 67.6%, and 61.5% respectively (P = 0.0001, 0.0001, and 0.043). Conclusion: Overall, the combination of tetracycline+levofloxacin is more efficient for HP eradication in comparison with clarithromycin+amoxicillin despite more complication rate. In areas with a high rate of resistance to clarithromycin, this therapeutic regimen could be an ideal choice for HP eradication, especially among those who were diagnosed with PUD.

Vibration Controlled Transient Elastography in Screening for Silent Liver Diseases.

OBJECTIVES: The objective of this study was to screen for significant hepatic fibrosis or steatosis in asymptomatic, apparently healthy subjects by using Vibration-controlled transient elastography and controlled attenuation parameter (CAP). METHODS: Prospectively, 433 asymptomatic apparently healthy adults were included. Fibroscan/CAP examination was performed for all of them. Subjects with liver stiffness measurement > 6 kPa or CAP >248 dB/m were further evaluated to assess underlying chronic liver disease. RESULTS: According to fibroscan/CAP examination, subjects were classified into four subgroups: normal (119) with CAP score of 215.85 ± 24.81 dB/m and fibrosis score of 4.47 ± 0.81 kPa, subjects with steatosis only 133 with CAP score of 309.41 ± 42.6 dB/m and fibrosis score of 4.74 ± 0.82 kPa, subjects with both steatosis and fibrosis 95 with CAP score of 318.20 ± 39.89 dB/m and fibrosis score of 7.92 ± 2.58 kPaand subjects with fibrosis only 86 with CAP score of 213.48 ± 22.62 dB/m and fibrosis score of 6.96 ± 1.11 kPa. S0 was present in 205 (47.3%), S1 in 48 (10.2%), S2 in 16 (3.7%) and S3 in 168 (38.8%) of studied subjects, whereas F0-1 was present in 371 (85.7%), F2 in 44 (10.16%), F3 in 16 (3.7%) subjects and F4 in only one (0.23%) subject. Subjects with both steatosis and fibrosis showed significantly higher transaminases, triglycerides and total cholesterol levels than other subgroups. CONCLUSIONS: Most asymptomatic, apparently healthy subjects (72%) have significant steatosis and fibrosis. Liver stiffness measurement and CAP might represent promising first-line noninvasive procedures to screen for silent liver diseases in the general population.

Epidermal growth factor rs4444903 polymorphism and risk of cholangiocarcinoma. A case control study.

Aim of the study: Cholangiocarcinoma (CCA) comprises a diverse group of malignancies that occur anywhere along the biliary tree. Gene polymorphisms are risk factors for CCA development. Expression levels of epidermal growth factor (EGF) are correlated with progressive tumor growth and metastasis by increasing tumor cell proliferation and migration. The EGF rs4444903 (G) allele seems to enhance carcinogenesis in several types of cancer. The aim was to study the association between epidermal growth factor EGF (rs4444903) gene polymorphism and risk of CCA in Egyptian patients. Material and methods: This case-control study included 100 subjects, 50 CCA patients and 50 healthy individuals as controls. The EGF (rs4444903) genotyping was performed by real-time polymerase chain reaction (PCR). Results: The risk of CCA increased more in subjects with GG and AG genotypes than in those with AA genotype compared to the control group (p = 0.009, 0.037, OR = 4.20, 2.83, 95% CI: 1.40-12.60, 1.05-7.60 respectively). The variant G allele showed a highly significant association with CCA risk in the dominant model (p = 0.009). However, in the recessive model the G allele showed a nonsignificant association with the risk of CCA (p = 0.075). There were no significant differences between the EGF rs4444903 SNP genotypes in terms of the size of foci and presence of chronic hepatitis C virus (HCV) infection in the CCA group (p = 0.220, 0.645, respectively). Conclusions: EGF rs4444903 polymorphism may have a role in the pathogenesis of CCA and the minor G allele may predispose to CCA, but it has no effect on severity of the disease.

Bone morphogenic protein-7 (BMP-7) polymorphism: Susceptibility to cirrhosis and hepatocellular carcinoma after viral hepatitis in Egyptian patients.

Aim of the study: Bone morphogenic proteins (BMPs) have both inhibitory and stimulatory effects on growth of a tumor that depend on the type of cells, the dosage and the tumor microenvironment. We aimed to investigate the impact of the bone morphogenic protein-7 (BMP-7) single nucleotide polymorphism (SNP) rs230205 [A/G] on susceptibility to hepatocellular carcinoma (HCC) progression from liver cirrhosis after viral hepatitis infection in Egyptian patients. Material and methods: The amplification-refractory mutation system (ARMS)-polymerase chain reaction (PCR) method was used to genotype the rs230205 [A/G] SNP in 150 subjects (50 patients with post-hepatitis C or B cirrhosis, 50 HCC patients, and 50 controls). Expression level of BMP-7 protein was assessed using enzyme-linked immunosorbent assay (ELISA). Results: The results revealed insignificant changes in distribution of all genotypes/alleles of the BMP-7 rs230205 [A/G] SNP between cirrhotic patients, HCC patients and controls. The AA genotype and A allele could be considered risk factors for cirrhosis (OR = 1.75, 1.50) and HCC (OR = 2.19, 1.74), respectively. The AA genotype (95% CI: 0.45-6.79) and A allele (OR = 1.50, 95% CI: 0.77-2.93) may be viewed as cirrhosis risk factors based on group segregation. Additionally, the A allele, AG and AA genotypes and their combined ORs of 2.19 (95% CI: 0.58-8.23), 1.74 (95% CI: 0.90-3.37), and 1.70 (95% CI: 0.68-4.29) could all be risk factors for HCC. No genotype or allele could be regarded as a risk factor for progression of cirrhosis to HCC, according to OR values. Conclusions: The results showed no correlation between BMP-7 rs230205 [A/G] SNP and progression of cirrhosis to HCC. To confirm our findings, additional prospective large-scale research is required.

Susceptibility patterns and virulence genotypes of Helicobacter pylori affecting eradication therapy outcomes among Egyptian patients with gastroduodenal diseases.

BACKGROUND: Helicobacter pylori (H. pylori) is a significant human pathogen that is responsible for a variety of illnesses, including mucosa-associated lymphoid tissue lymphoma, gastric cancer, peptic ulcers, and gastritis. AIM: To investigate the frequency of H. pylori infection and its resistance patterns among Egyptian patients and to determine the influence of H. pylori virulence genetic determinants on the eradication success of 14-d triple therapy regimen. METHODS: H. pylori infections were investigated in 72 patients with gastroduodenal complications suggestive of H. pylori infection. The cagA and vacA genotypes of cultured strains were studied using polymerase chain reaction. The patients underwent 14 d of triple-therapy treatment. The treatment response was examined using histology and a rapid urease test 6 wk after therapy discontinuation. RESULTS: The intention-to-treat eradication rate was 59.2% (95%CI: 48.2%-70.3%). Rates of H. pylori resistance to clarithromycin, amoxicillin, and metronidazole were 52.8%, 81.9%, and 100%, respectively. Successful eradication of H. pylori was more significantly associated with vacA s1-positive strains [adjusted odds ratio (aOR) = 0.507, 95%CI: 0.175-0.822]. A significant association was found between failed eradication rate and H. pylori strains resistant to clarithromycin (aOR = 0.204, 95%CI: -0.005 to 0.412) and amoxicillin (aOR = 0.223, 95%CI: 0.026-0.537). CONCLUSION: This study's low H. pylori eradication rate following 14-d triple therapy is concerning and worrying. H. pylori pan-resistance to metronidazole followed by the high resistance to ciprofloxacin, amoxicillin, and clarithromycin in this research is challenging and of great concern.

Hypokalemia as a responsible factor related with the severity of hepatic encephalopathy: a wide multination cross-sectional study.

Several precipitating factors of hepatic encephalopathy have been recognized and studied. Hepatic encephalopathy which is a frequent and grave complication of liver failure, is associated with multiple biochemical changes like high serum ammonia, mercaptan and phenol levels, low albumin levels and derangements in electrolytes. It is characterized by a range of neuronal and psychological aberrations mainly due to the inability of liver to metabolize different neurotoxic chemicals produced in the body. Hypokalemia is one of the most important findings in hepatic encephalopathy and postulated as a precipitating factor of the condition. The authors aimed to know the frequency of hypokalemia and its relation to the severity of hepatic encephalopathy. Methods: After taking approval from the hospital ethical review committee, a total of 5000 patients with hepatic encephalopathy were recruited by consecutive sampling. They were interviewed, examined and investigated for serum potassium levels and other precipitating factors of hepatic encephalopathy. Results: Total of 5000 patients including 3070 (61.4%) males and 1930 (38.6%) females, aging 13 years and above were studied. The frequency of hypokalemia was 78% (3900 patients). Relating the serum potassium level with the severity of hepatic encephalopathy, 1200 (60%) out of 2000 patients with serum potassium below 2.5 mEq/l were in grade 4 (40%) and 800 out of 2000 were in grade 3 encephalopathy. On the other hand, only 700 patients (6.4%) out 1100 with serum potassium above 3.4 mEq/l were in grade 4 encephalopathy. Conclusion: Hypokalemia is a frequent finding in patients with hepatic encephalopathy and found to be directly related to its severity.

Lymphoepithelioma-like Hepatocellular Carcinoma: a Case Report and Review of Literature.

We report a case of hepatic lymphoepithelioma-like carcinoma-hepatocellular carcinoma subtype (LEL-HCC) in a 41-year-old man with chronic hepatitis C virus (HCV) infection. The patient presented with abdominal pain and further assessment revealed a hypoechoic mass on ultrasonography. Serum alpha-fetoprotein (AFP) was 13·6 ng/dl. The patient was diagnosed as hepatocellular carcinoma based on the established triphasic computed tomography (TCT) diagnostic criteria and he underwent a surgical resection of the mass. Microscopic examination showed sheets and cords of malignant epithelial cells intermixed with heavy lymphoid infiltrate, with more than 100 tumor-infiltrating lymphocytes (TILs) per 10 high-power-field (HPF). Based on immunohistochemical studies, the malignant cells were positive for Hep Par 1 and glypican 3, focally positive for cytokeratin 7 (CK7), and negative for cytokeratin 20 (CK20). TILs were diffusely positive for cluster of differentiation 3 CD3 with an approximately equal CD4/CD8 ratio. The patient was recurrence free at 25 months after surgery, as evident by CT and serum alpha-fetoprotein level. LEL-HCC is a rare variant of HCC with a relatively better prognosis. Exploring the potential for immune modulator-based therapy in this subset of tumors is highly recommended.

Role of liver biopsy in management of liver diseases without hepatic nodules following end of the interferon era: experience of a tertiary referral center.

Liver biopsy (LB) is the cornerstone in the management of patients with liver diseases. However, a lot of queries had emerged about its role following the end of the interferon era. The aim of this study was to re-evaluate the current role of LB in the diagnosis of liver diseases. All patients who had underwent LB at the Department of Hepatology, National Liver Institute, from January 2015 through December 2018 were recruited. Indications for LB, pathology reports and medical records of all cases were retrieved, reviewed and statistically analyzed. A total of 275 liver biopsies were collected, 191 males and 84 females with mean age 41.22 ± 13.36 years. Etiological diagnosis made by histopathological evaluation was 48 drug-induced liver injury (DILI), 42 nonalcoholic fatty liver disease (NAFLD), 34 chronic hepatitis B, or C with cholestasis, 29 autoimmune hepatitis, 34 primary sclerosing cholangitis, 13 primary biliary cholangitis, 7 autoimmune overlap syndrome, 13 active bilharziasis and 10 Wilson's disease. Minor number of cases was diagnosed by different other etiologies. Initial diagnosis was made by liver biopsy and confirmed by clinical response and laboratory findings. Liver biopsy is still considered as the gold standard diagnostic measure of different liver diseases representing an integral component of management decisions in hepatology.

Evaluation of Amino Acids Profile as Non-Invasive Biomarkers of Hepatocellular Carcinoma in Egyptians.

BACKGROUND: Hepatocellular carcinoma (HCC) is the most dangerous complication of chronic liver disease. It is a multifactorial complicated disease. Hepatitis C and hepatitis B viruses (HCV and HBV, respectively) represent the main causes of HCC in Egypt. Early diagnosis is very important to aid in early intervention. OBJECTIVES: The goal of this research is to evaluate the metabolic role of different amino acids as non-invasive biomarkers over the course of HCC. METHODS: This study included 302 participants with 97 diagnosed, untreated HCC patients, 81 chronic HCV patients, 56 chronic HBV patients, 18 co-infected patients, and a control group of 50 normal age and gender-matched individuals. All participants provided complete medical histories and underwent complete clinical examinations, abdominal ultrasonography and/or computed tomography, routine laboratory investigations, estimation of serum α-fetoprotein, and determination of amino acid levels using ultra-performance liquid chromatography (UPLC MS/MS). RESULTS: This work revealed a decline in branched chain amino acids (BCAA) and increase in aromatic amino acids (AAA) among infected groups (HCC, HBV, HCV, and co-infected patients) compared to control subjects and a marked change in Fisher's and the BCAAs/tyrosine molar concentration ratios (BTR) between controls and infected groups. CONCLUSION: Different amino acids could be used as non-invasive markers to discriminate and follow chronic hepatitis patients to predict the course of HCC.

Impact of prothrombin and factor V Leiden mutations on the progression of fibrosis in patients with chronic hepatitis C.

BACKGROUND: The role of thrombotic factors in the pathogenesis and progression of liver fibrosis remains obscure. We aimed to study the relationship between prothrombin G20210A (PT20210) and factor V Leiden (FVL) mutations and the progression of fibrosis and liver function in chronic HCV patients. METHODS: The study included 100 subjects, 88 patients with HCV-related cirrhosis (compensated: 38, decompensated: 50), and 12 controls. Patients with other viral hepatitis or coinfection, inherited metabolic disease, autoimmune hepatitis, hepatic or extrahepatic malignancy, in addition to patients with causes of hypoalbuminemia, elevated bilirubin or prolonged INR not related to cirrhosis were excluded from the study. Relevant clinical data were collected and basic laboratory tests were performed. Liver fibrosis was assessed using APRI and FIB-4 scores. FVL and PT20210 mutations were analyzed. RESULTS: FVL and PT20210 mutations were significantly higher in decompensated vs. compensated patients (32% vs. 5.3%, P = 0.001; 20% vs. 5.3%, 0.043, respectively) and absent in controls. Both mutations significantly correlated to the duration of infection, platelet count and fibrosis scores. PT20210 mutation significantly correlated to serum albumin and INR. Both mutations significantly predicted fibrosis scores, especially PT20210 (AUROC: 0.833 for APRI and 0.895 for FIB-4). CONCLUSIONS: Both mutations are significantly correlated to fibrosis progression and liver profile and could be considered as markers predicting the need for early and different intervention.

Value of Bile Acids in Diagnosing Hepatitis C Virus-Induced Liver Cirrhosis and Hepatocellular Carcinoma.

Background: Metabonomic studies have related bile acids to hepatic impairment, but their role in predicting hepatocellular carcinoma still unclear. The study aimed to examine the feasibility of bile acids in distinguishing hepatocellular carcinoma from post hepatitis C virus-induced liver cirrhosis. Methods: An ultra-performance liquid chromatography coupled with mass spectrometry measured 14 bile acids in patients with noncirrhotic post hepatitis C virus disease (n = 50), cirrhotic post hepatitis C virus disease (n = 50), hepatocellular carcinoma (n = 50), and control group (n = 50). Results: The spectrum of liver disease was associated with a significant increase in many conjugated bile acids. The fold changes in many bile acid concentrations showed a linear trend with hepatocellular carcinoma > cirrhotic disease > noncirrhotic disease > healthy controls (p < 0.05). Receiver operating characteristic curve analysis revealed five conjugated acids TCA, GCA, GUDCA, TCDCA, GCDCA, that discriminated hepatocellular carcinoma from noncirrhotic liver patients (AUC = 0.85-0.96) with a weaker potential to distinguish it from chronic liver cirrhosis (AUC = 0.41-0.64). Conclusion: Serum bile acids are associated primarily with liver cirrhosis with little value in predicting the progress of cirrhotic disease to hepatocellular carcinoma.

Hepatitis C Virus Infection in Eastern Libya: Efforts Needed to Improve HCV Testing and Linkage to Care in the Resource-Limited Setting.

Hepatitis C virus (HCV) is a significant public health problem, and the elimination of its infection by 2031 is a global goal. However, due to insufficient testing, lack of linkage to care (LTC) and treatment, Libya may be far from achieving this goal. This study aimed to explore HCV testing, the care and treatment of infected people, and to assess the burden of the infection among individuals who visited the main Medical Centre in Tobruk region, eastern Libya, for various medical and surgical conditions. A research team interviewed public health officials in Tobruk Medical Center, inspected available equipment, and obtained data available for people who were positive for antibodies to HCV (anti-HCV) as part of their routine pre-invasive procedures and pre-donation screening tests from January 2005 to April 2020. HCV antibody tests were positive for 612 cases out of 368,392 (0.17%). Of those who tested positive for anti-HCV antibodies, no one had followed up by RNA test for identifying individuals with chronic HCV infection, and there are no links to outpatient care and treatment. Our findings highlight the critical need for an up-to-date HCV diagnosis and linkage to care guidelines, which includes a follow-up RNA test for anti-HCV positive patients and early linkage to care for confirmed cases to accelerate the elimination of HCV infection from the community.

The association between micro-RNA gene polymorphisms and the development of hepatocellular carcinoma in Egyptian patients.

INTRODUCTION: The development and progression of hepatocellular carcinoma (HCC) is a multistage process involving the deregulation of genes that are crucial to cellular processes. Multiple risk factors are correlated with HCC. MicroRNA is differentially expressed in the development of different types of malignancies, including hepatic malignancy. Single nucleotide polymorphisms (SNPs) are the most common sequence variation in the human genome. SNPs in miRNAs may affect transcription, processing, or target recognition and result in malignant disease. The aim of the study was to determine the association between microRNA gene polymorphisms and the development of HCC in Egyptian patients. MATERIAL AND METHODS: This study included 200 individuals who were matched in age and sex. Tumour staging was done using the BCLC staging system. Quantification and genotyping of microRNA were performed. RESULTS: Among the 200 patients, 2 groups were described: group I included 90 HCC patients with a male majority (72.2%), and group II comprised 110 controls. Three microRNA SNPs were assayed in both patients and controls. There was a significant association between rs10061133 miR-499b and the risk of HCC. The genotypes GG or G allele were significantly associated with an increased risk of HCC (GG: OR = 2.91, 95% CI: 1.23-4.22, p = 0.013; G allele: OR = 1.79, 95% CI: 1.12-2.15, p = 0.026) compared with the genotype of AA or AG or A allele. CONCLUSIONS: There is an association between the miRNA SNPs and the susceptibility to HCC, to explore some roles and mechanisms of SNPs within miRNAs in the occurrence and development of HCC.

Helicobacter pylori versus platelet-to-spleen ratio as a risk factor for variceal bleeding in patients with liver-cirrhosis-related portal hypertension.

Background Acute upper gastrointestinal (GIT) bleeding is a common medical emergency clinically manifested by hematemesis and/or melena. This study aimed to elucidate the roles of Helicobacter pylori and the platelet-spleen ratio as risk factors for variceal bleeding in patients with portal hypertension secondary to liver cirrhosis. Methods The study was conducted on 200 patients with liver cirrhosis of various etiologies who were divided into two groups: group 1 included 100 patients with liver cirrhosis and portal hypertension with or without a history of upper GIT bleeding, and group 2 included 100 patients with liver cirrhosis without portal hypertension. Upper GIT endoscopy was performed, and biopsy samples were taken from the gastric antral mucosa for rapid urease testing. The platelet-spleen diameter ratio was calculated for all patients. Results In group 1, most patients who had a history of variceal bleeding were H. pylori-negative whereas most patients without a history of variceal bleeding were H. pylori-positive, implying that H. pylori may play a significant role as a protective factor against variceal bleeding. The calculated odds ratio for the rapid urease test was low (0.851), whereas the calculated odds ratio for the platelet-spleen diameter ratio was higher (9.766) than that for the rapid urease test. Thus, the rapid urease test plays a significantly higher role than the platelet-spleen ratio as a risk factor for bleeding (p-value = 0.001).
