Helicobacter pylori (H. pylori) is a major etiological factor of peptic ulcer disease (PUD). It is supposed to be a risk factor for the more frequently encountered PUD in patients with liver cirrhosis. Several investigators have evaluated the effect of H. pylori on liver cirrhosis, portal hypertensive gastropathy (PHG) and encephalopathy with controversial results. Some reports have shown a higher seroprevalence and suggested a synergistic effect of H. pylori on liver cirrhosis and PHG. However, this increased prevalence is associated with a negative histology and is not influenced by the cause of cirrhosis, PHG, Child class or gender. Most studies have not found any correlation between H. pylori and PHG. In contrast, other studies have reported a markedly lower prevalence of H. pylori in cirrhotics with duodenal ulcer compared to controls. The aim of this article is to review the relationship between H. pylori infection and portal hypertensive gastropathy and the role of H. pylori eradication in cirrhotic patients.

Congestive myelopathy secondary to epidural venous engorgement and venous congestion in a patient with Budd-Chiari syndrome and its management through inferior vena cava stenting.
BMJ Case Rep

Budd-Chiari syndrome with obstruction in the inferior vena cava causes increased venous pressure in the azygous-hemiazygous system and paravertebral venous plexus, which is transmitted to the epidural venous plexus, devoid of the valves. It causes epidural venous plexus engorgement and venous congestion and may present rarely with low back pain or radiating pain. However, patients developing lower limb weakness as a complication of Budd-Chiari syndrome is an infrequent and severe presentation.

Common variable immunodeficiency (CVID) is a type of primary immunodeficiency that presents as a heterogenous disorder characterized by hypogammaglobinemia, poor response to vaccines, recurrent sinopulmonary infections, and can have noninfectious systemic manifestations. We performed a single-center, retrospective, observational study of five patients with noninfectious complications of CVID. All patients had CVID as defined by the European Society of Immunodeficiencies criteria and had received intravenous immunoglobulin therapy.
