Antibacterial therapy for Crohn's disease: a review emphasizing therapy directed against mycobacteria

Autor: K, Hultén, A, Almashhrawi, F A, El-Zaatari, D Y, Graham

Publikováno v: Digestive diseases and sciences. 45(3)

The most commonly used antibiotics in Crohn's disease are nitroimidazoles and macrolides often combined with corticosteroids or sulfasalazine. There has been interest in a mycobacterial involvement in Crohn's disease since its earliest description. I

The differential diagnosis of early gastric mucosa-associated lymphoma: polymerase chain reaction and paraffin section immunophenotyping

Autor: H M, El-Zimaity, F A, El-Zaatari, M P, Dore, S, Oweiss, O, Gutierrez, M, Yuksul, J, Ramchatesingh, D Y, Graham

Publikováno v: Modern pathology : an official journal of the United States and Canadian Academy of Pathology, Inc. 12(9)

The distinction between benign florid lymphoid hyperplasia and low-grade gastric mucosal-associated lymphoid tissue (MALT) lymphoma may be a challenge. The presence of monoclonal B cells in Helicobacter pylori-chronic active gastritis has suggested t

REP-PCR fragments as biomarkers for differentiating gastroduodenal disease-specific Helicobacter pylori strains

Autor: D H, Kwon, F A, El-Zaatari, J S, Woo, C L, Perng, D Y, Graham, M F, Go

Publikováno v: Digestive diseases and sciences. 43(5)

We previously identified four potential putative gastroduodenal disease fragments by using the interspersed repetitive extragenic palindromic DNA sequence based PCR (REP-PCR) technique. We investigated these fragments with regard to their disease spe

The interaction of pH, bile, and Helicobacter pylori may explain duodenal ulcer

Autor: S W, Han, D G, Evans, F A, el-Zaatari, M F, Go, D Y, Graham

Publikováno v: The American journal of gastroenterology. 91(6)

Inhibition of Helicobacter pylori growth by bile suggests that it should be difficult for H. pylori to colonize the duodenum and cause duodenal ulcer. To search for a common mechanism, we investigated the relationship between H. pylori strain (duoden

Helicobacter pylori in the oral cavity. A critical review of the literature

Autor: A M, Nguyen, F A, el-Zaatari, D Y, Graham

Publikováno v: Oral surgery, oral medicine, oral pathology, oral radiology, and endodontics. 79(6)

Helicobacter pylori is now generally accepted as a key etiologic agent in peptic ulcer disease as well as in gastric cancer. Dental plaque has been implicated as a possible source of H. pylori by studies that used culture, biochemical, nucleic acid,

Diagnosis of intestinal tuberculosis by polymerase chain reaction on endoscopic biopsy specimens

Autor: B S, Anand, F E, Schneider, F A, El-Zaatari, R M, Shawar, J E, Clarridge, D Y, Graham

Publikováno v: The American journal of gastroenterology. 89(12)

It is often difficult to establish the diagnosis of intestinal tuberculosis because of close similarities with other conditions, in particular, Crohn's disease. In the present study, we used the polymerase chain reaction (PCR) assay on endoscopic bio

In vitro mutagenesis of HLA-B27. Amino acid substitutions at position 67 disrupt anti-B27 monoclonal antibody binding in direct relation to the size of the substituted side chain

Autor: F A, el-Zaatari, K C, Sams, J D, Taurog

Publikováno v: Journal of immunology (Baltimore, Md. : 1950). 144(4)

The class I MHC molecule HLA-B27 bears an unpaired Cys residue at position 67, which is predicted to face the Ag binding pocket, based on the x-ray crystallographic model of HLA-A2. To investigate the potential of this residue in the antigenic struct

Restriction fragment length polymorphism of T cell receptor alpha and beta chain genes in patients with ankylosing spondylitis

Autor: J P, Durand, F A, el-Zaatari, A M, Krieg, J D, Taurog

Publikováno v: The Journal of rheumatology. 15(7)

Ankylosing spondylitis (AS) is very strongly associated with the class I major histocompatibility (MHC) antigen HLA-B27. Because class I MHC antigens function as restricting elements recognized by T cell antigen receptors, we sought to determine if t
