Hepatitis B Screening Prior to Chemotherapy in the Middle East: A Retrospective Cohort Study

Background: Hepatitis B virus (HBV) reactivation can be asymptomatic or manifest as fatal fulminant hepatitis. Most international guidelines recommend screening patients prior to immunosuppressive therapy. Aims: To determine HBV screening rates and modalities in patients receiving chemotherapy at the American University of Beirut Medical Center. Methods: A retrospective cohort review of electronic health records of  adult patients who received chemotherapeutic agents, between June 2015 and June 2016. Patients clinical characteristics were documented. Adequate screening was defined as performing all: HBsAg, HBs Abs, and anti HBc Abs(total). Results: A total of 1547 patients were initially assessed. 45.6% were males with a mean age of 56. 382(30%) had hematologic malignancies, of whom 111 underwent HSCT. Of those included, 303(24%) patients were screened by at least one test for HBV and 42(3.3%) for HBsAg, anti HBc Abs and HBs Abs. Patients who were appropriately screened were significantly younger(p=0.008) and more likely to have hematologic malignancies (n=35, 83.3%, p<0.0001). Among patients with hematologic malignancies, appropriately screened patients (n=35) were younger (p=0.042) and had a history of HSCT(n=19, 54.3%, p=0.001). Conclusion: Rates of screening for HBV prior to chemotherapy at our medical center are low, and not always complete or adequate. There is an urgent need to implement a better screening policy

Small Bowel Tumors: Clinical Presentation, Prognosis, and Outcome in 33 Patients in a Tertiary Care Center

Introduction. Small bowel cancers are rare. Accumulation of data regarding their clinical presentation, pathologic features, prognostic factors, treatment modalities, and outcome is difficult. Methods. This is a retrospective study of the medical records of 33 patients with small bowel cancers treated at the American University of Beirut-Medical Center over a 20-year period. Results. The study included 25 males (76%) and 8 females (24%). Median age at presentation was 56 years. Most common symptoms were abdominal pain (66.7%) and weight loss (57.6%). Thirteen patients presented with abdominal emergencies (39.3%). Lymphoma was the most common malignant tumor (36.4%), followed by adenocarcinoma (33.3%), leiomyosarcoma (15.2%), gastrointestinal stromal tumors (12.1%), and neuroendocrine tumors (3.0%). Tumors were located in the duodenum in 30% of patients, jejunum in 33%, and ileum in 36%. Resectability rate was 72.7% and curative R0 resection was achieved in 54.1% (13/24) of patients. 5-year survival of the 33 patients was 24.2%. Conclusion. Small bowel cancers are difficult to diagnose because of the nonspecific symptoms. Most patients present with advanced disease and have poor prognosis. Adenocarcinoma and duodenal location have the worst 5-year survival in contrast to stromal tumors and those with ileal location which have the best survival

Esophageal Cytomegalovirus and Herpes Simplex virus co-infection in an immunocompromised patient: Case report and review of literature

Herpes simplex virus and Cytomegalovirus co-infection has been reported to occur in a variety of sites in immunocompromised patients. To our knowledge, few cases of such co-infection have been reported to occur in the esophagus. We report a case of a 60-year-old woman who was maintained on immunosuppressive therapy for a presumed diagnosis of pemphigus vulgaris, who presented with odynophagia. Investigations revealed ulcerative esophagitis caused by both HSV and CMV. The patient was treated with valganciclovir with full recovery. We also present the results of various studies on patients with similar presentation particularly those caused by HSV and CMV co-infection

Celiac disease in Middle Eastern and North African countries: A new burden?

Celiac disease (CD) is now recognized as a common disorder among Middle Eastern (ME) and North African (NA) populations. The aim of this review is to assess the available data regarding CD in the ME and NA and to compare this information with that of Western countries. A literature review was performed using the electronic databases PubMed and Medline (1950-2008) as search engines, and “celiac disease” was used as a Mesh term. The search was limited to ME and NA countries. The prevalence of CD in ME and NA countries among low risk populations is similar to that of Western countries, but is higher in high risk populations such as those with type 1 diabetes. It is underestimated because of lack of clinical suspicion and lack of patient awareness. Clinical presentations in term of gastrointestinal, hematologic, skeletal, and liver manifestations are similar between both populations except for a high prevalence of short stature in some ME and NA countries. Few studies have addressed atypical or silent CD. As in the West, diagnosis is initially made by serological tests and is confirmed by small intestinal biopsies. Gluten-free diet is the main mode of treatment with a higher apparent adherence rate than in the West. Most disease complications result from malabsorption. The disease is strongly associated with HLA DQ2 and to a lesser extent with HLA DQ8 alleles. In conclusion, CD prevalence is underestimated, with little data available about its malignant complications. Disease parameters in the ME and NA are otherwise similar to those in Western countries
