Pantoprazole prophylaxis in ICU patients with high severity of disease: a post hoc analysis of the placebo-controlled SUP-ICU trial.

Purpose: In the subgroup of patients with Simplified Acute Physiology Score (SAPS) II > 53 in the Stress Ulcer Prophylaxis in Intensive Care Unit (SUP-ICU) trial, there was interaction (P = 0.049) suggesting increased mortality in patients allocated to pantoprazole as compared with placebo. We aimed to explore this further.

Stress ulcer prophylaxis versus placebo or no prophylaxis in adult hospitalised acutely ill patients-protocol for a systematic review with meta-analysis and trial sequential analysis.

Background: Stress ulcer prophylaxis is considered standard of care in many critically ill patients in the intensive care unit (ICU). However, the quality of evidence supporting this has recently been questioned, and clinical equipoise exists. Whether there is overall benefit or harm of stress ulcer prophylaxis in adult hospitalised acutely ill patients is unknown.

Reduced baroreflex sensitivity and pulmonary dysfunction in alcoholic cirrhosis: effect of hyperoxia.

Patients with cirrhosis exhibit impaired regulation of the arterial blood pressure, reduced baroreflex sensitivity (BRS), and prolonged QT interval. In addition, a considerable number of patients have a pulmonary dysfunction with hypoxemia, impaired lung diffusing capacity (Dl(CO)), and presence of hepatopulmonary syndrome (HPS). BRS is reduced at exposure to chronic hypoxia such as during sojourn in high altitudes.

Pulmonary dysfunction and hepatopulmonary syndrome in cirrhosis and portal hypertension.

Background: Pulmonary dysfunction including the hepatopulmonary syndrome (HPS) is an important complication to cirrhosis and portal hypertension. However, the precise relation to liver dysfunction and the prevalence of HPS are unclear.

Aims: We therefore aimed to assess (i) the prevalence of HPS in consecutive alcoholic cirrhotic patients, (ii) the degree of pulmonary dysfunction in relation to liver function and (iii) the response of a 100% oxygen test on cardiopulmonary and peripheral oxygenation.

The heart and the liver.

Cardiac failure affects the liver and liver dysfunction affects the heart. Chronic and acute heart failure can lead to cardiac cirrhosis and cardiogenic ischemic hepatitis. These conditions may impair liver function and treatment should be directed towards the primary heart disease and seek to secure perfusion of vital organs.

Combined effects of moderately elevated blood glucose and locally produced TGF-beta1 on glomerular morphology and renal collagen production.

Background: There is a correlation between renal graft rejection and blood glucose (BG) levels. Furthermore, diabetic patients may develop non-diabetic renal diseases, which in some circumstances progress rapidly. Since transforming growth factor-beta1 (TGF-beta) levels are elevated in many renal diseases, the accelerated progression may be due to interactions between glucose and locally produced TGF-beta1.

Plasminogen activator inhibitor-1 gene deficiency attenuates TGF-beta1-induced kidney disease.

Background: Transforming growth factor-beta1 (TGF-beta1) stimulates the deposition of extracellular matrix (ECM), which is a hallmark in end-stage renal disease. The importance of TGF-beta1-induced changes in protease activity in this process is not fully elucidated. TGF-beta1 up-regulates plasminogen activator inhibitor type 1 (PAI-1), which lowers matrix degradation.
