Eosinophilic ascites as an uncommon presentation of eosinophilic gastroenteritis: A case report.

BACKGROUND: Eosinophilic gastroenteritis (EGE) is defined by the presence of gastrointestinal symptoms, with an abnormal eosinophilic infiltrate of the intestine wall and exclusion of other causes of secondary eosinophilia. EGE has three clinical presentations, depending on the depth of eosinophilic infiltration of the bowel wall. It individualizes into three types, namely mucosal, muscular, and subserosal. Eosinophilic ascites, which is caused by edema and eosinophilic inflammation of the serosal layer of the small bowel wall, is the most uncommon presentation of EGE. CASE SUMMARY: A 30-year-old Egyptian woman presented with pain in the epigastrium and diffuse abdominal distension. Past medical history comprised allergy to iron injections (for iron deficiency anemia). Clinical examination showed moderate abdominal distention (palpation) and shifting dullness (percussion) suggestive of moderate ascites; mild right pleural effusion was also suspected, but findings were otherwise unremarkable. Abdominal and pelvic examinations by ultrasound and contrast-enhanced computed tomography showed moderate ascites, mild right pleural effusion, and diffuse thickening of the antrum and small bowel loops. Endoscopy of the upper gastrointestinal tract revealed mild diffuse hyperemia of the esophagus, stomach and duodenum, with no relevant findings in the histopathology of biopsy specimens taken from these sites. Laboratory results showed eosinophilia in the peripheral blood and marked increase of eosinophils in the ascitic fluid. Treatment with corticosteroids resulted in normalization of the laboratory test results, and the ascites resolved within a week of initiation of therapy. CONCLUSION: Eosinophilic ascites, characterized by increased eosinophils in peripheral blood and ascitic fluid, showed dramatic response to steroid therapy.

Performance of Disease-Specific Scoring Models in Intensive Care Patients with Severe Liver Diseases.

INTRODUCTION: Egypt has the highest prevalence of Hepatitis C Virus (HCV) in the world, estimated nationally at 14.7%. HCV treatment consumes 20% ($80 million) of Egypt's annual health budget. Outcomes of cirrhotic patients admitted to the ICU may, in fact, largely depend on differences in the state of the disease, criteria and indications for admission, resource utilization, and intensity of treatment. AIM: The aim of the present study was to evaluate the efficacy of liver specific scoring models in predicting the outcome of critically ill cirrhotic patients in the ICU as it may help in prioritization of high risk patients and preservation of ICU resources. MATERIALS AND METHODS: Over one year, a total of 777 patients with End Stage Liver Disease (ESLD) due to HCV infection were included in this retrospective non-randomized human study. All statistical analyses were performed by the statistical software SPSS version 22.0 (SPSS, Chicago, IL, USA). Child Turcotte Pugh (CTP) score, MELD score, MELD-Na, MESO, iMELD, Refit MELD and Refit MELD-Na were calculated on ICU admission. RESULTS: ICU admission was mainly due to Gastrointestinal (GI) bleeding and Hepatic Encephalopathy (HE). Overall mortality was 27%. Age and sex showed no statistical difference between survivors and non survivors. Significantly higher mean values were observed for all models among individuals who died compared to survivors. MELD-Na was the most specific compared to the other scores. MELD-Na was highly predictive of mortality at an optimized cut-off value of 20.4 (AURC=0.789±0.03-CI 95%=0.711-0.865) while original MELD was highly predictive of mortality at an optimized cut-off value of 17.4 (AURC=0.678±0.01-CI 95%=0.613-0.682) denoting the importance of adding serum sodium to the original MELD. INR, serum creatinine, bilirubin, white blood cells count and hyponatremia were significantly higher in non survivors compared to survivors, while hypoalbuminemia showed no statistical difference. The advent of Hepatorenal Syndrome (HRS) and Spontaneous Bacterial Peritonitis (SBP) carried worse prognosis. Hyponatremia and number of transfused blood bags were additional independent predictors of mortality. CONCLUSION: In cirrhosis of liver, due to HCV infection, patients who died during their ICU stay displayed significantly higher values on all prognostic scores at admission. The addition of sodium to MELD score greatly improves the predictive accuracy of mortality. MELD-Na showed the highest predictive value of all scores.

Circulating miRNAs as Predictor Markers for Activation of Hepatic Stellate Cells and Progression of HCV-Induced Liver Fibrosis.

INTRODUCTION: Liver fibrosis is the excessive accumulation of extracellular matrix that occurs by activation of hepatic stellate cells (HSCs), which has been identified as the major driver of liver fibrosis. Several studies confirmed that miRNAs have regulatory effects on the activation of HSCs by affecting the signaling pathways. The aim of this study was to develop non-invasive diagnostic markers by measuring different circulating miRNAs in serum as predictor markers for early diagnosis of liver fibrosis and its progression. METHODS: In this case-control study, we enrolled 66 subjects with chronic hepatitis C (CHC) with early stage of fibrosis and 65 subjects with CHC with late-stage fibrosis. Also, 40 subjects were included as normal controls. The six main miRNAs, i.e., miR-138, miR-140, miR-143, miR-325, miR-328, and miR-349, were measured using the reverse transcription-polymerase chain reaction. RESULTS: In the cases of CHC both with early and late stage of fibrosis, the circulating levels of the six main miRNAs were significantly higher than the levels in the control group. ROC analysis indicated that the sensitivity and specificity of miR-138 were 89.3% and 71.43%, respectively, in the early stage of fibrosis. In the late stage, the sensitivity and specificity of miR-138 were 89.3 and 93.02%, respectively, whereas, for miR-143, they were 75.0 and 88.4%, respectively. CONCLUSIONS: Circulating miR-138 could serve as a non-invasive biomarker for the detection of early fibrosis. Also, miR-138 and miR-143 could be specific biomarkers for indicating the late stage of liver fibrosis.

ROLE OF T REGULATORY CELLS IN CHRONIC HCV INFECTED EGYPTIAN PATIENTS AND THEIR IMPACT ON THE RESPONSE TO PEGYLATED INTERFERON THERAPY.

Treatment of patients with chronic hepatitis C with the current standard pegylated interferon (PEG-IFN) and ribavirin achieves overall response (SVR) rates of ~55%. A role of CD4+ CD25+ regulatory T cells (Treg cells) has been proposed as they can suppress HCV-specific T cells in HCV-infected patients. Patients with chronic HCV legible for PEG-IFN plus ribavirin treatment, were classified according to their response to treatment into two groups (responders and non-responders, 32 and 27 patients respectively). Blood and plasma samples were collected at the start of treatment and at 12 and 24 weeks during treatment. Immunophenotyping by flow cytometry for Treg cells, the FOXP-3 expression using real-time PCR and measurement of IL-10, TGF-ß CXCL-9 and CXCL-10 were performed. Increased expression of Treg cells was detected in patients who didn't respond to treatment before and during treatment. Also, the levels of IL-10, TGF-ß, CXCL-9 and CXCL-10 revealed significant increase.in non-responders all through compared to responders group. Evaluation of Treg cells, cytokines (IL-10 & TGF-ß) and chemokines (CXCL-9 & CXCL-10) before starting the treatment could be a predictor of response to treatment with PEG-IFN plus ribavirin. The optimum levels which would differentiate between responders and non-responders are needed to be defined before-hand.

Predictors of In-Hospital Mortality in patients with hepatocellular carcinoma and Acute Variceal bleeding.

INTRODUCTION: Detection of hepatocellular carcinoma (HCC) in cirrhotic patients remains a serious, unsolved problem, and the risk factors for acute variceal bleeding (AVB) in HCC patients remain unclear. This study aimed to determine the in-hospital mortality (IHM) and factors influencing the clinical outcomes of AVB in patients with liver cirrhosis and HCC. METHODS: This was a retrospective, non-randomized, clinical study that was conducted in 2014. The study was conducted on 70 patients with liver cirrhosis and HCC presenting by acute upper gastrointestinal bleeding (AUGIH). All patients were examined endoscopically within 24 hours from presentation and bleeding varices accounted for AUGIH. Full medical history, clinical examination, and laboratory and radiologic data were collected from admission charts, and hospital medical records were statistically analyzed with SSPS version 22. RESULTS: Thirty-two patients (45.7%) survived and 38 died (54.3%). Survivors are more likely to be Child-Pugh class A or B, and the non-survivors were class C. The Model for End-Stage Liver Disease (MELD) was highly predictive of IHM at an optimized cut-off value of ≥ 12.9. Higher esophageal varices grades and presence of active bleeding on index endoscopy were significant (p < 0.01) in the non-survivors compared to survivors. Complications of liver cirrhosis and associated major comorbidity were significantly higher (p < 0.01) in the non-survivors than the survivors. Univariate logistic regression analysis identified higher Grade Esophageal Varices and number of transfused packed red blood cells units as two independent predictors of IHM. CONCLUSIONS: IHM was particularly high (54.3%) among HCC patients with AVB who had MELD score > 12.9, higher grade Esophageal Varices, active bleeding on index endoscopy, more increased needs for blood transfusion, longer hospital stay, decompensated liver disease with major comorbidity.

Impact of hyponatremia on frequency of complications in patients with decompensated liver cirrhosis.

INTRODUCTION: Hyponatremia is common in cirrhosis. The relationship between hyponatremia and severity of cirrhosis is evidenced by its close association with the occurrence of complications, the prevalence of hepatic encephalopathy, hepatorenal syndrome, spontaneous bacterial peritonitis, refectory ascites, and hepatic hydrothorax. The aim of this study was assess the impact of hyponatremia on the occurrence of both liver-related complications and the hemodynamic cardiovascular dysfunction. METHODS: This prospective study was conducted in 2015 on 74 patients with liver cirrhosis. The patients were from the Gastroenterology and Hepatology Department of Theodor Bilharz Research Institute in Giza, Egypt. The patients were divided into three groups according to their serum level of sodium. Group 1 included 30 patients with serum sodium >135 meq/L, group 2 included 24 patients with serum sodium between135 and 125 meq/L, and group 3 included 20 patients with serum sodium <125 meq/L. For each of the patients, we conducted aclinical examination, laboratory investigations, chest X-ray, ECG, abdominal sonar, and echocardiography. RESULTS: Hyponatremia was found in 59.46% of our cirrhotic patients, and they showed significantly increased Model for End-Stage Liver Disease (MELD) score, MELD-Na score, QTc interval, Pulmonary vascular resistance (PVR) and inferior vena cava (IVC) collapsibility, and decreased SVR and IVC diameter. Also hepatic encephalopathy, ascites, renal failure, infectious complications, and pleural effusion were significantly more common in hyponatremic cirrhotic patients. CONCLUSION: In cirrhosis, hyponatremia is more common in severe cardiovascular dysfunction and associated with increased risk of hepatic encephalopathy, ascites, illness severity scores, renal failure, infectious complications, and pleural effusion. We recommend selective oral administration of vasopressin V2-receptor antagonist, tolvaptan, which acts to increase the excretion of free water, thereby resolving hypervolemic hyponatremia and may have the potential to improve outcomes in these patients.

Systemic vascular resistance and fluid status in patients with decompensated liver cirrhosis with or without functional renal failure in Egypt.

BACKGROUND: Functional renal failure and cardiovascular dysfunction are common complications of liver cirrhosis. This study aimed to evaluate cardiac performance, systemic vascular resistance (SVR) and fluid status in patients with decompensated liver cirrhosis either with or without functional renal failure. METHODS: Sixty patients diagnosed as having decompensated liver cirrhosis were divided into two groups. Group 1 included 30 patients with decompensated liver cirrhosis with ascites and with creatinine values ≤ 1.5 mg/dl. Group 2 included 30 azotemic decompensated cirrhotic patients with diagnostic criteria of hepatorenal syndrome (HRS). Also, 20 healthy subjects, of matched age and sex to the Group 1 and Group 2 patients, were included in the study as the control group. All patients and normal controls were subjected to clinical examination, laboratory evaluation, ECG, abdominal ultrasonography and echocardiographic studies. RESULTS: The echocardiographic and ECG data showed significant increase in LAD (P<0.01, P<0.01), AoD (P<0.05, P<0.01), interventricular septum thickness (IVST) (P<0.01, P<0.01), posterior wall thickness (PWT) (P<0.01, P<0.01), EDD (P<0.01, P<0.01), ESD (P<0.05, P<0.01), left ventricular (LV) mass (P<0.01, P<0.01), and Corrected QT (QTc) (P<0.01, P<0.01) interval with significant decrease in SVR (P<0.01, P<0.01). Additionally, there was significant decrease in IVC diameter in both patients groups compared to the control group (P<0.01, P<0.01). CONCLUSION: Patients with decompensated liver cirrhosis have low SVR, and Doppler echocardiography provides an easy noninvasive tool to assess this finding. Also, these patients demonstrate small inferior vena cava (IVC) diameter with normal collapsibility, which indicates low effective plasma volume. Measuring IVC diameter and collapsibility are of value in the prediction of intravascular fluid status in liver cirrhosis. This is especially true with renal dysfunction. Early addition of oral vasoconstrictors in decompensated patients may correct the SVR and circulatory dysfunction and hinder HRS occurrence.

Insulin resistance: a major factor associated with significant liver fibrosis in Egyptian patients with genotype 4 chronic hepatitis C.

BACKGROUND AND AIMS: The role of insulin resistance (IR) in chronic hepatitis C genotype 4 (CHC-4) patients is still under assessment. The aims of this study are to assess the prevalence and predictors of IR and its influence along with clinical, metabolic, virological, and histological factors on the severity of liver fibrosis in 100 Egyptian patients with CHC-4. PATIENTS AND METHODS: In 100 untreated patients with CHC-4, IR was assessed using the Homeostasis Model Assessment and defined greater than 3. By logistic regression (LR), independent factors associated with IR and significant fibrosis (SF=fibrosis, Metavir score≥F2) were assessed in nondiabetic and noncirrhotic patients. RESULTS: One hundred patients were included; 54% were men and 46% were women. The mean age of the patients was 40.46±9.41 years. Of the total patients, 55% were overweight and 28% were obese. Metabolic syndrome was observed in 26% of patients; five of them were known to be diabetic. All patients were genotype 4. Most of our patients had mild viremia (<2 00 000 IU/ml), whereas only 16% had higher viral load (>2 00 000 IU/ml). There was no correlation between IR and hepatitis C virus viremia (r=-0.069; P=0.492). Necroinflammation was moderate-severe (A2-A3) in 25% of patients. SF (F2-F4) was found in 46% of patients and 11% had cirrhosis (F4). Most of our patients, 54%, had moderate steatosis and 21% had severe steatosis. IR was present in 46% of patients; 39 (42.9%) were nondiabetic, which is correlated significantly with BMI (r=0.395; P<0.01). IR was found to increase significantly with the fibrosis stage (P=0.001), insignificant fibrosis, 18.5%, SF (F2-F4), 71.4%, and cirrhosis (F4), 100%. By LR, IR was independently and significantly associated with age more than 40 years, obesity (BMI>30 kg/m), SF, and severe steatosis (>30%). IR was also significantly associated with metabolic syndrome. SF was present in 46 patients (46%). It was associated with IR, moderate-severe necroinflammation, and severe steatosis. By LR, in noncirrhotic patients, SF was associated with age more than 40 years, obesity (BMI>30 kg/m), moderate/severe liver inflammation, and severe steatosis. CONCLUSION: In CHC-4 patients, IR is highly prevalent and independently associated with age, obesity, SF, and severe steatosis. Management of IR might significantly improve the prognosis of CHC-4 patients.

Efficacy and safety of a novel pegylated interferon alpha-2a in Egyptian patients with genotype 4 chronic hepatitis C.

BACKGROUND: Hepatitis C virus (HCV) genotype 4 is a common infection in Egypt and is the leading cause of liver disease. OBJECTIVE: To study the efficacy and safety of a novel 20 kD pegylated interferon alpha-2a derived from Hansenula polymorpha in combination with ribavirin for the treatment of Egyptian patients with genotype 4 chronic hepatitis C (CHC). METHODS: One hundred seven patients with genotype 4 CHC were involved in the present study. Liver biopsy was performed in all patients. All patients received a fixed weekly dose of 160 µg of a novel pegylated interferon in combination with ribavirin in standard and adjusted doses. Serum HCV RNA levels were assessed by a real-time sensitive polymerase chain reaction assay at four, 12, 48 and 72 weeks after the start of therapy. Patients demonstrating an early virological response (EVR) completed a 48-week course of treatment. RESULTS: The overall sustained virological response (SVR) was 60.7%. The SVR in patients with a rapid virological response was significantly higher (91.7%) than in patients with complete EVR (67.74%) (P=0.033) and partial EVR (56.14%) (P=0.003). SVR was also significantly higher in patients with a low degree of liver fibrosis according to Metavir score (F1 and F2) (67.57%) compared with those with a high degree of liver fibrosis (F3 and F4) (45.45%) (P=0.017). The baseline viral load had no impact on SVR in the present series nor were any serious adverse events reported. CONCLUSION: The novel pegylated interferon alpha-2a assessed in the present study was effective for the treatment of patients with genotype 4 CHC, and was safe and well tolerated.

The use of whey protein concentrate in management of chronic hepatitis C virus - a pilot study.

INTRODUCTION: Whey protein contains biologically active ingredients that can prevent and attenuate disease besides being nutritive. The aim of the study was to clarify the effects of oral administration of whey protein on viral load and host defence mechanisms, in particular, phagocytic function of neutrophils, selected immunomodulatory cytokines and serum inflammatory markers, in compensated chronic hepatitis C virus (HCV) patients. MATERIAL AND METHODS: Twenty-seven HCV patients (20 males and 7 females) recruited from the hepatology clinic of the Theodor Bilharz Research Institute (TBRI) were given whey protein concentrate (WPC) twice daily for two months. In addition, 15 age and sex matched healthy participants were included in the study, as a control group. Neutrophil phagocytic activity, serum intercellular adhesion molecule (sICAM), interleukin-2 (IL-2), nitric oxide (NO), as well as HCV-RNA levels and routine investigations were determined for patients, before and after WPC supplementation and once for the control group. RESULTS: There was a significant decrease in viral load and markers of active inflammation, alanine aminotransferase (ALT) and aspartate aminotransferase (AST), while serum albumin, total leucocyte counts and absolute neutrophil counts showed significant elevation accompanied by improvement of neutrophil phagocytic activity after WPC supplementation compared to pre-treated levels. The oral WPC supplementation was well tolerated without any serious adverse events. CONCLUSIONS: Oral supplementation of WPC has promising results as a new therapeutic strategy against HCV and its sequelae by decreasing the viral load and active inflammation as well as improving the synthetic capacity of the liver and the phagocytic function of neutrophils, in these patients.

Mesh repair of non-complicated umbilical hernia in ascitic patients with liver cirrhosis.

The policy of elective repair of umbilical hernia in cirrhotic ascitic patients has long been a subject of debate and is still a major health problem. This study evaluated the role and outcome of elective mesh repair of umbilical hernia in cirrhotic ascitic patients, compared with the conventional two layers fascial repair technique. Forty cases with a small to medium sized umbilical hernia defects in ascitic cirrhotic patients were divided into two groups (GI & GII) of 20 patients each. After proper control of ascites in both groups, patients in GI were subjected to elective umbilical hernia onlay mesh repair. In GII, hernias were managed by conventional two layers fascial repair. In GI, transient early postoperative ascitic fluid leakage occurred in 3 (15%) cases and mild superficial wound infection in 5 (25%) cases which was controlled by antibiotics. Two (10%) cases developed hernia recurrence during follow up period. In GII, ascitic leakage occurred in 6 (30%) cases that responded well to conservative management except only one case needed re-exploration and repair reenforcement. Drainage was significantly less than in GI in amount (P<0.05) and duration (P<0.01), wound infection occurred in 3 (15%) cases but were superficial and controlled conservatively. Recurrence occurred in 7 cases (35%). Elective mesh repair of umbilical hernia with ascites in cirrhotic patients proved to be a safe, simple and effective technique with perioperative antibiotics and proper aseptic procedure.

Current status of sensitivity to praziquantel in a focus of potential drug resistance in Egypt.

A decade ago, a study revealed that praziquantel (PZQ) failed to cure 1.6% of those with intestinal schistomiasis in five villages of the Nile delta region. The recommended dosage of PZQ is a single 40 mg/kg oral dose, and each of these patients continued to pass viable Schistosoma mansoni eggs despite three successive doses at or above this level. The eggs passed by these uncured villagers produced adult worms that were, in most cases, significantly less responsive to PZQ in vitro. This report investigates the current sensitivity of S. mansoni infections to PZQ after 10 years of therapeutic pressure in the same villages, testing the hypothesis that the number of drug failures would have increased as continued drug pressure selected for worms with diminished sensitivity to PZQ. The data show that these villages have experienced a significant decrease in the prevalence and intensity of S. mansoni infections, with present infection rate of 10.9%, compared with 25.1% in 1994. The first treatment resulted in normal range of cure rates, between 73.8 and 92.3% in each of the five villages in the study. After three successive doses (40, 40, and 60 mg/kg, the same treatment protocol applied a decade ago) there were no uncured patients remaining in the study. This shows that there has not been an increase of drug failure, despite 10 years of therapeutic pressure in these villages where there had been resistant infections and worms with decreased response to PZQ.

Efficacy of mirazid in comparison with praziquantel in Egyptian Schistosoma mansoni-infected school children and households.

This trial investigated the anti-schistosomal activity of mirazid in comparison with that of praziquantel in Schistosoma mansoni-infected Egyptian patients. The sample population was composed of 1,131 individuals (459 school children and 672 household members). Screening for S. mansoni was conducted using the standard Kato Katz technique. Four slides from a single stool sample were examined before treatment, and four slides per sample from stool samples obtained on three consecutive days were examined post-treatment. All positive eligible subjects were randomly assigned into two groups, the first received mirazid at a dose of 300 mg/day for three consecutive days, and the second received praziquantel at a single dose of 40 mg/kg. All treated subjects were examined 4-6 weeks post-treatment. Mirazid showed low cure rates of 9.1% and 8.9% in S. mansoni-infected school children and household members, respectively, compared with cure rates of 62.5% and 79.7%, respectively, in those treated with praziquantel. Therefore, we do not recommend mirazid as an agent to control schistosomiasis.
