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.

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

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. 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).

Vilazodone-phospholipid mixed micelles for enhancing oral bioavailability and reducing pharmacokinetic variability between fed and fasted states.

Despite the effectiveness and high tolerability of vilazodone (VLZ) as an antidepressant, its use is still limited due to its poor solubility and food dependent absorption. This study aims to load VLZ-phospholipid complex into self-assembled micelles forming VLZ-PL mixed micelles (VLZ-PL-MM), that can enhance VLZ solubility, improve its bioavailability and reduce the pharmacokinetic variability between the fed and fasting conditions. The effect of surfactant type and concentration was assessed using four different non-ionic surfactants (Brij 58, Tween 80, Labrasol and Pluronic F127) in four different weight ratios between the drug-complex and surfactant (1:0.

Predictors of azathioprine toxicity in children with autoimmune hepatitis.

Aim Of The Study: Azathioprine (AZA) is an important steroid-sparing drug in the management of autoimmune hepatitis (AIH). Avoidance of its adverse events that could be severe and carry a risk of mortality in a few cases is important, preferably with cheap and easy assessments that could be feasible in developing countries with the unavailability of molecular assays. Assessment of thiopurine methyltransferase (TPMT), the key enzyme for the inactivation of AZA, as a predictor of AZA toxicity had been a matter of conflict.

Remodeling Lipids in the Transition from Chronic Liver Disease to Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is a worldwide health problem. HCC patients show a 50% mortality within two years of diagnosis. To better understand the molecular pathogenesis at the level of lipid metabolism, untargeted UPLC MS-QTOF lipidomics data were acquired from resected human HCC tissues and their paired nontumor hepatic tissues ( = 46).

Sugar Alcohols Have a Key Role in Pathogenesis of Chronic Liver Disease and Hepatocellular Carcinoma in Whole Blood and Liver Tissues.

The major risk factors for hepatocellular carcinoma (HCC) are hepatitis C and B viral infections that proceed to Chronic Liver Disease (CLD). Yet, the early diagnosis and treatment of HCC are challenging because the pathogenesis of HCC is not fully defined. To better understand the onset and development of HCC, untargeted GC-TOF MS metabolomics data were acquired from resected human HCC tissues and their paired non-tumor hepatic tissues ( = 46).

First report of glycogen storage disease type 111a in a Nigerian child.

Glycogen storage disease (GSD) is a rare inborn error of metabolism with an incidence of 1/20,000-40,000 live births. Some of the presenting clinical features can mimic diseases commonly seen in the tropics and subtropics. We report a 14-month-old Nigerian child who presented at our institution with GSD Type 111a to alert physicians on the need to consider and recognise this rare disorder.

Chromatographic determination of some biomarkers of liver cirrhosis and hepatocellular carcinoma in Egyptian patients.

Metabolomics has been shown to be an effective tool for disease diagnosis, biomarker screening and characterization of biological pathways. A total of 140 subjects were included in this study; urine metabolomes of patients with liver cirrhosis (LC, n = 40), patients with hepatocellular carcinoma (HCC; n = 55) and healthy male subjects (n = 45) as a control group were studied. Gas chromatography/mass spectrometry-based urine metabolomics profiles were investigated for all participants.

Effect of different therapeutic modalities on systemic, renal, and hepatic hemodynamics and short-term outcomes in cirrhotic patients with spontaneous bacterial peritonitis.

Background: Spontaneous bacterial peritonitis (SBP) is a major risk factor for hepatorenal syndrome. Albumin infusion has been shown to prevent renal impairment and reduce mortality in SBP. The study aimed to compare the effect of different therapeutic modalities on hemodynamics and short clinical outcomes in high-risk patients with SBP.

Impact of nitazoxanide on sustained virologic response in Egyptian patients with chronic hepatitis C genotype 4: a double-blind placebo-controlled trial.

Background: Nitazoxanide, approved for the treatment of Cryptosporidium parvum and Giardia lamblia, was found to inhibit hepatitis C virus replication.

Aim: The aim of this study was to assess the impact of nitazoxanide as an add-on therapy to pegylated interferon α-2a and ribavirin on sustained virologic response (SVR) in patients with chronic hepatitis C.

Patients And Methods: A total of 200 patients with chronic hepatitis C were enrolled in the study, assigned randomly in a 1 : 1 ratio to two groups: group A (placebo group) and group B (nitazoxanide group).

Neutrophil Gelatinase-Associated Lipocalin: A New Marker of Renal Function in C-Related End Stage Liver Disease.

Background/Aims. Renal impairment is a common complication of cirrhosis. Serum creatinine is less sensitive in these patients.

Urinary urobilinogen in biliary atresia: A missed, simple and cheap diagnostic test.

Aim: Early diagnosis of biliary atresia (BA) is of utmost importance for good outcome; however, it is sometimes difficult due to the overlapping diagnostic test results with other causes of neonatal cholestasis. Moreover, many diagnostic tests are costly, invasive and not available in all centers, especially in developing countries. So, we aimed to investigate the diagnostic performance of urinary urobilinogen; an easy, cheap test that was not tested before in BA.

A comparative study of variants of pegylated interferon alpha in treatment of chronic HCV patients.

HCV infection presents a vast burden in the regions of high prevalence such as Egypt, where most HCV isolates are genotype 4b. Combined treatment of three variants of pegylated interferon and ribavirin is still the standard of care in Egypt. However, no conclusive data confirming their efficacy are available.

miR-210 is a prognostic marker in clear cell renal cell carcinoma.

Accurate assessment of prognosis of clear cell renal cell carcinoma (ccRCC) is key in optimizing management plans to fit individual patient needs. miRNAs are short noncoding single-stranded RNAs that control the expression of target genes and may act as cancer biomarkers. We analyzed the expression of miR-210 in 276 cases of primary ccRCC and compared its expression in 40 pairs of adjacent normal and cancerous tissues.

Kallikreins as microRNA targets: an in silico and experimental-based analysis.

microRNAs (miRNAs) are non-coding RNAs that target specific mRNAs. They have been shown to control many biological processes including cancer pathogenesis. Kallikreins (KLKs) are a family of serine proteases that are attracting interest as cancer biomarkers.

Plasma protein advanced glycation end products, carboxymethyl cysteine, and carboxyethyl cysteine, are elevated and related to nephropathy in patients with diabetes.

In Diabetes Mellitus (DM), glucose and the aldehydes glyoxal and methylglyoxal modify free amino groups of lysine and arginine of proteins forming advanced glycation end products (AGEs). Elevated levels of these AGEs are implicated in diabetic complications including nephropathy. Our objective was to measure carboxymethyl cysteine (CMC) and carboxyethyl cysteine (CEC), AGEs formed by modification of free cysteine sulfhydryl groups of proteins by these aldehydes, in plasma proteins of patients with diabetes, and investigate their association with the albumin creatinine ratio (ACR, urine albumin (mg)/creatinine (mmol)), an indicator of nephropathy.
