CHARACTERIZATION OF THE CYTOXIN-ASSOCIATED GENE A (CAGA GENE) IN HELICOBACTER PYLORI USING GASTRIC BIOPSIES
The alignment of the deduced protein sequences confirmed that there were no East Asian type EPIYA-D sequences in Iraqi strains. A significant association was found between increase in number of EPIYA-C motifs and GU compared with gastritis. Otherwise, the number of EPIYA C motifs did not associate with DU, indicating predictive association with the severity of the disease. Conclusions: The structure of the 3' region of the CagA gene in Iraqi strains was Western type with a variable number of EPIYA-C motifs. In 20 strains, the CM motifs were identical to those common in Western strains.

  HEPATIC ENCEPHALOPATHY
A high percentage of patients with chronic liver disease progresses to cirrhosis complicated by hepatic encephalopathy (HE). This presents with neurological impairments ranging from subclinical dysfunction to coma. Its management is based on eliminating the precipitating factors and decreasing the toxin load with adequate bowel motions or altering bowel flora.
