Decreased Phagocytosis and Intracellular Killing of Bacteria in Leukocytes of Geriatric Patients with Clostridioides difficile Infections.

Introduction: Patients suffering from a Clostridioides difficile infection have a higher overall mortality than patients with similar comorbidities.

Methods: Whole blood samples of 15 patients with C. difficile enteritis and 15 control patients matched for age and sex were used to analyze the capacity of blood phagocytes to internalize and kill encapsulated Escherichia (E.

Reduced Clostridioides difficile infections in hospitalised older people through multiple quality improvement strategies.

Objectives: To reduce infections with Clostridioides difficile (CDI) in geriatric patients by interventions easily implementable in standard clinical care.

Methods: Prevalence and incidence of CDI between January 2015 and February 2020 were analysed (n = 25,311 patients). Pre-intervention status was assessed from April 2016 to March 2017 (n = 4,922).

Tuberculosis in newly arrived asylum seekers: A prospective 12 month surveillance study at Friedland, Germany.

Purpose: In the European Union tuberculosis prevalence-rates are among the lowest in the world. The prevalence of active tuberculosis in migrant populations has to be analyzed to get valid data on the risk of tuberculosis and for the decision of screening activities.

Methods: Therefore, we prospectively quantified the risk of active tuberculosis among asylum seekers at time of arrival.

Acute paranoid psychosis as sole clinical presentation of hepatic artery thrombosis after living donor liver transplantation.

Background: Hepatic artery thrombosis is a devastating complication after orthotopic liver transplantation often requiring revascularization or re-transplantation. It is associated with considerably increased morbidity and mortality. Acute cognitive dysfunction such as delirium or acute psychosis may occur after major surgery and may be associated with the advent of surgical complications.

Clinical staging of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is one of the most common cancers in the world. The resistance of HCC to existing treatments and the lack of biomarkers for early detection make it one of most hard-to-treat cancers. Surgical tumor resection, including liver transplantation, remains the only curative modality for HCC.

Hepatitis C virus virology and new treatment targets.

Hepatitis C virus (HCV) infection is the leading cause of chronic liver disease. An estimated 130 million people worldwide are persistently infected with HCV. Almost half of patients who have chronic HCV infection cannot be cured with the standard treatment consisting of pegylated IFN-alpha and ribavirin.

Interferon-alpha therapy does not modulate hepatic expression of classical type I interferon inducible genes.

Hepatitis C virus (HCV) infection is a major cause of chronic liver disease. Treatment with interferon-alpha(2) (IFN-alpha(2)) can induce viral clearance and marked biochemical and histological improvement. IFN-alpha(2) treatment has been shown to stimulate the expression of type I IFN regulated genes in peripheral blood mononuclear cells (PBMCs) of hepatitis C patients; however, whether it affects hepatic expression remains unknown.

Expression of AFP and Rev-Erb A/Rev-Erb B and N-CoR in fetal rat liver, liver injury and liver regeneration.

Background: Alpha-fetoprotein (AFP) expression can resume in the adult liver under pathophysiological conditions. Orphan nuclear receptors were supposed to regulate AFP gene expression, in vitro. We were interested to study the expression of AFP and orphan nuclear receptors, in vivo.

Treatment of genotype 2 and 3 chronic hepatitis C virus-infected patients.

Aim: Before pegylated interferon alpha (IFN) was introduced for the therapy of chronic hepatitis C virus (HCV)-induced hepatitis, conventional thrice weekly IFN therapy was supplemented by ribavirin. Also, at that time, higher and more frequent doses of IFN were expected to be more effective than the standard regimen of 3 MU thrice weekly. As ribavirin significantly increases side effects and negatively influences the quality of life particularly in young patients, we started a prospective non-randomized study with a daily IFN-2a monotherapy as an initial treatment for chronic hepatitis C.

Interferon type I gene expression in chronic hepatitis C.

Hepatitis C virus (HCV) frequently causes chronic liver disease. The cause of viral persistence might be an inappropriate type I interferon (IFN) induction. To analyze the host's IFN response in chronic hepatitis C, we measured the transcription level of type I IFN genes as well as type I IFN-regulated genes in liver tissue and corresponding blood samples from patients with chronic hepatitis C, nonviral liver diseases, and a suspected but later excluded liver disease.

Ribavirin inhibits DNA, RNA, and protein synthesis in PHA-stimulated human peripheral blood mononuclear cells: possible explanation for therapeutic efficacy in patients with chronic HCV infection.

The treatment of choice for patients infected chronically with HCV is the combination of IFN-alpha and ribavirin. Monotherapy with ribavirin leads to a clinical and histological improvement, but its exact mechanism of action is unknown. Therefore, the effect of ribavirin on synthesis of inflammatory cytokines and on apoptosis in stimulated peripheral blood mononuclear cells (PBMCs) was investigated.

Renal responses to desflurane and isoflurane in patients with renal insufficiency.

Background: The most consistent risk factor for postoperative renal failure is poor preoperative renal function. Desflurane is not contraindicated in patients with renal disease, but the data regarding its effects on renal function in these patients are sparse.

Methods: Only patients with preexisting renal disease were recruited into the study.
