Background: In developed countries, hepatitis A virus (HAV) infection occurs mainly in adults. It is usually symptomatic and may cause acute liver failure (ALF). In patients with chronic liver disease, serum ferritin levels (SFL) can predict short-term prognosis.

Objectives: To determine whether admission SFL can serve as a prognostic marker in patients with HAV infection.

Methods: A retrospective analysis of 33 adults with HAV infection was conducted. Because none of our patients presented with ALF, the parameter "length of hospital stay," was used as a surrogate marker of disease severity.

Results: The mean (± SD) at admission SFL was 2529 ± 4336 ng/ml. SFL correlated with the levels of international normalized ratio (INR), liver enzymes, and degree of hemolysis that occurred during the disease course. SFL did not correlate with the levels of either albumin or bilirubin or with the length of the hospital stay. The mean length of hospital stay was 5.1 ± 2.0 days, which correlated with the levels of INR, albumin, and bilirubin as well as the degree of hemolysis. However, in multivariate analysis only albumin and bilirubin predicted the length of the hospital stay. Follow-up SFL, which were available only in eight patients, decreased during the hospital stay.

Conclusions: In adults with acute HAV infection, SFL may be increased. SFL correlated with the degree of liver injury and hemolysis that occur during the disease. However, in our cohort of HAV patients, who had a relatively benign disease course, SFL were of no prognostic value.

Background: Since the implementation of a hepatitis A virus (HAV) immunization program for children, which began in 1999 in Israel, HAV infections in the country have occurred mostly in adults. HAV infection in adults is usually symptomatic and may present with hepatic, as well as extrahepatic, abdominal complications.

Objectives: To estimate the prevalence of extrahepatic abdominal complications in patients diagnosed with HAV.

Methods: Most extrahepatic abdominal complications corresponding to HAV infection have ultrasonographic manifestations; therefore, we retrospectively collected findings from ultrasound examinations in addition to laboratory data from adult patients with HAV infection who were admitted to our medical center between 2004 and 2016. Associations between ultrasonographic findings and laboratory parameters that reflect disease severity were identified.

Results: A total of 43 consecutive adult patients were included in this study. None presented with fulminant hepatic failure. Thirty patients (70%) had at least one ultrasonographic finding. Ascites was noted in 8 patients, a thickened gallbladder wall was observed in 14, pericholecystic fluid was found in 8, and biliary sludge was observed in 4. Significant associations included the presence of any ultrasonographic finding and peak total bilirubin levels (P = 0.021), the presence of ascites with peak aspartate and alanine aminotransferase levels (P = 0.041 and P = 0.038, respectively), and the presence of biliary sludge and nadir albumin during the HAV disease course (P = 0.037).

Conclusions: Abdominal ultrasonographic findings, such as ascites and gallbladder abnormalities, are frequently observed during acute HAV infection and are significantly associated with disease severity.

Background: Carotid artery stenting is used as an alternative to surgical endarterectomy.

Objectives: To determine the outcome of CAS[1] in a retrospective cohort of patients.

Methods: Between July 1999 and March 2003, 56 consecutive patients with carotid artery stenosis who were considered ineligible for surgery were treated (45 male, 11 female, mean age 69). All cases were performed prior to the introduction of distal protective devices in Israel.

Results: Intraprocedural complications included transient neurological findings in 5 patients (8%), cerebrovascular accident in 2 (3%), hemodynamic changes in 11 (18%), and 4 procedural failures. Post-procedural complications included transient ischemic attack in 3 patients and cardiovascular accident in 6 (10%). At 30 days follow-up, three patients (5%) remained with signs of CVA[2]. Two patients (3%) died during the post-procedural period and 16 (28%) during the 5 year follow-up, one due to recurrent CVA and the remainder to non-neurological causes. Five-year carotid Doppler follow-up was performed in 25 patients (45%), which revealed normal stent flow in 21 (84%), 50–60% restenosis in 3 patients (12%) and > 70% restenosis in one patient (4%).

Conclusions: This study confirms that stent procedures are beneficial for symptomatic carotid stenosis in patients not eligible for surgery.

Background: Recurrent abdominal pain is a common pediatric diagnostic problem.  Endoscopy is sometimes performed as part of the evaluation. Although gastritis and/or Helicobacter pylori infection is often present, it is not known if they contribute to the symptomatology.

Objectives: To evaluate the role of either gastritis or H. pylori infection in the symptomatology of children with RAP.

Patients and Methods: We retrospectively studied two groups of patients, 70 children in each, who had undergone endoscopy. One group was evaluated endoscopically for RAP and the other was a heterogeneous group that underwent endoscopy for indications other than RAP. Biopsies were taken during endoscopy and Giemsa staining was performed for the presence of H. pylori. Triple therapy was given as indicated, and the children were followed for an average of 6 months.

Results: Microscopic gastritis was diagnosed in 39 patients (55.7%) of the RAP group and in 31 of the heterogeneous group (44.2%) (NS), and H. pylori was found in 32 patients of the RAP group and in 16 of the heterogeneous group (45.7% vs. 22.8%, P<0.01). All children with H. pylori, except one in the heterogeneous group, had accompanying gastritis. On the other hand, gastritis without H. pylori infection was seen in 7 children in the RAP group and in 15 of the other. Endoscopy revealed macroscopic abnormalities in 52 of the 70 children with microscopic gastritis. There was a clinical improvement after triple therapy in 28 of 33 children with H. pylori-associated gastritis (84.85%), in 4 of 8 children with gastritis unassociated with H. pylori (50%), and in 8 of 15 without gastritis or H. pylori (53.3%) (P<0.01 between the H. pylori-associated gastritis and each of the other groups).

Conclusions: H. pylori infection and gastritis may be associated with RAP in a selected subgroup of children. We recommend a complete work-up, including endoscopy and invasive or non-invasive diagnostic modalities for H. pylori, and treatment of the infection.
