Abstract
BACKGROUND Polymorphisms of certain genes may have an effect on either persistence of infection or spontaneous clearance of hepatitis C virus (HCV). We hypothesized that one or more variants of chemokines (CCL2 and CCL5) and chemokine receptors (CC chemokine receptor type 2 [CCR2]) genes are associated with the susceptibility to HCV infection. METHODS We recruited 1460 patients with chronic HCV (CHC), 108 subjects with spontaneous virus clearance (SVC) and 1446 individuals as a healthy control group. All were genotyped for single nucleotide polymorphisms: rs13900 C/T of CCL2, rs3817655 T/A of CCL5 and rs743660 G/A and rs1799864 G/A of CCR2 using allelic discrimination real-time PCR technique. RESULTS The carriage of the A allele of CCR2 rs743660 was significantly higher in CHC compared to SVC (odds ratio [OR] 4.03) and to controls (1.42) and in controls compared to SVC (2.85) (all P < 0.01). Similarly, the A allele of CCR2 rs1799864 was significantly higher in the CHC group when compared with both SVC (1.97) and controls (2.13) (both P < 0.01), but the OR between controls and SVC was not significant (1.08, P = 0.723). Carriage of C allele of CCL2 rs13900 and the T allele of CCL5 rs3817655 were significantly higher in SVC group when compared with both CHC (OR = 0.19 and OR = 0.24, respectively) and control groups (OR = 0.65 and OR = 0.45, respectively [all P < 0.01]). CONCLUSIONS Susceptibility to HCV infection is associated with A alleles of both (rs743660 and rs1799864 G/A) of CCR2 while spontaneous clearance of HCV is associated with the C allele of rs13900 of CCL2 and T allele of rs3817655 of CCL5.

Abstract
Hepatitis C infection is a global pandemic. HLA-DQB1 alleles are believed to have an effective role in immune response against HCV including susceptibility to or protection from this infection. The aim of this study was to investigate the contribution of HLA-DQB1 alleles in the outcome of HCV genotype-4 infection through a family-based association study. Egyptian families with HCV (324) were recruited for this study (324 index positive for RNA-HCV, 225 positive relatives representing chronic hepatitis C cases and 582 family members negative for HCV-RNA [control], 63 of whom spontaneously cleared the virus. All subjects were genotyped for HLA-DQB1 alleles by sequence-specific primers (SSP-PCR) and sequence-based typing (SBT) methods. The frequency of DQB1*02:01:01 carriage was significantly higher in infected patients when compared to controls and those who spontaneously cleared virus (OR=5.47, P<.0001 and OR= 6.5234, P<.0001, respectively), and the carriage of the DQB1*03:01:01:01 allele was significantly higher in those who cleared and controls when compared to the infected patients (OR=0.2889, P<.0001 and OR=0.3016, P<.0001, respectively). On the other hand, the frequency of DQB1*06:01:01 and QB1*05:01:01:01 alleles was not associated with infection (comparison of infected and cleared patients showed OR of 2.1598 [P<.01]), but it becomes nonsignificant after adjustments with the Bonferroni formula (PC >0.05) and OR= 1.3523, P>.05, respectively. This study shows that clearance of HCV is associated with DQB1*03:01:01:01 allele and chronicity of HCV infection associated with the risk allele: DQB1*02:01:01.

Abstract
The discovery of Helicobacter hepaticus as a causal agent of hepatitis and hepatocellular carcinoma (HCC) in mice has stimulated interest in looking for Helicobacter species in human liver samples. In this study, we searched for association between H. pylori and HCV-related liver disease. Liver specimens were collected from eighty-five patients; they were divided into five different groups according to liver pathology (METAVIR system). Group I (the 1st control group) consisted of 16 patients with chronic hepatitis C without histological activity. Group II consisted of 25 patients with chronic active hepatitis C, Group III, 17 patients with HCV-related cirrhosis and Group IV, 16 patients with HCV-related cirrhosis and HCC. Group V (2nd control group) consisted of 11 patients suffering from gastro duodenal and gall bladder diseases but negative for HCV. All cases were tested by polymerase chain reaction on liver samples for the presence of H. pylori DNA Cag A gene. Routine biochemical, radiological and RT-PCR for HCV RNA were also performed for all cases. The positivity of H. pylori PCR CagA gene in liver tissue was directly proportional to the severity of liver pathology, this being 75%, 52.9% and 32% in groups IV, III and II, respectively, which was more significant than the 1st and 2nd control groups (P < 0.001). There was a significant difference between H. pylori PCR values when compared to METAVIR staging (F) in different groups (P = 0.001). Helicobacter pylori PCR (Cag A gene) was positive in about 28.2% cases of late fibrosis (F3 + F4) while positivity was (5.9%) in early fibrosis (F1 + F2) (P = 0.0001). There was significant difference between H. pylori PCR (Cag A gene) in liver tissue and METAVIR activity in different groups (P = 0.002) as most of H. pylori PCR-positive cases were METAVIR activity A1 and A2 (15.3% and 12.9%, respectively). There was no association between H. pylori PCR and quantitative HCV RNA (P = 0.531). Also there was no significant difference of Child-Pugh staging in the H. pylori PCR-positive group when compared to the negative group (P = 0.996). There may be an association between the presence of H. pylori (Cag A gene) in the liver and disease progression in HCV-related chronic hepatitis and cirrhosis with and without HCC.

Abstract
There was statistically significant difference between all groups of giardiasis patients regarding the grade of CD4 lymphocyte infiltration (P<0.001), being more marked in symptomatic group. The prevalence of flatulence, anorexia and vomiting were more frequent in patients with heavy CD4 lymphocyte infiltration in duodenum. A high statistical significant increase was in the mean OD values of anti-Giardia duodenal secretory IgA in patients with marked CD4 infiltration in duodenum. But, a statistical insignificant difference in mean OD values of anti-Giardia total serum Ig in patients with different grades of CD4 infiltration in symptomatic group. There was statistically significant increased in the mean OD values of anti-Giardia total serum Ig in patients with marked intraepithelial CD8 lymphocyte Infiltration in the duodenum In the asymptomatic group, there was statistically insignificant difference in the mean OD values of anti-Giardia total serum Ig in patients with different grade of intra-epithelial CD8 infiltration in symptomatic group. There is statistically significant increased in the mean OD values of anti-Giardia total serum Ig in patients with marked intra-epithelial CD8 lymphocyte infiltration in the duodenum regarding immunohistochemical staining of Giardia antigen in duodenal biopsies. All the 61 symptomatic giardiasis patients revealed Giardia antigen stains in their duodenal biopsies with a sensitivity of 100% while asymptomatic group a sensitivity of 93.181%. None in the controls showed positive Giardia antigen in the duodenal biopsies with 100% specificity.

Abstract
Malnutrition is known to have adverse effects on the physiology and morphology of the liver. The aim of this investigation was to examine the effect of protein restriction on the content of plasma membrane proteins residing in the sinusoidal and bile canalicular domains of rat liver. Post-weanling rats maintained on low protein isocaloric diets showed marked growth retardation concomitant with reduced liver protein concentration compared to control animals. The content of leucine aminopeptidase, a bile canalicular enzyme, and asialoglycoprotein receptor, a sinusoidal receptor, in livers of protein-restricted rats was 66% and 50%, respectively, of control livers. In contrast, the relative concentrations of dipeptidyl peptidase IV and a cell adhesion molecule (GP 110), both canalicular proteins, were 160% and 121%, respectively, in rat livers upon protein restriction. After a 4-week rehabilitation period, the concentrations of all canalicular membrane proteins were similar to those in control livers, while the sinusoidal receptor was only 68% of control values. Protein restriction was found to adversely affect the concentrations of protein constituents, but not their localization in the hepatocyte plasma membrane. In general, altered concentrations of hepatocyte membrane proteins were reversed on the administration of a normal protein diet.
