Long-Term Outcomes of Intravenous Ustekinumab Maintenance Treatment in Patients With Loss of Response to Subcutaneous Dosing.

Background: Ustekinumab (UST) is commonly used to treat Crohn's disease and ulcerative colitis. However, some patients may experience diminishing response or require increased dosage. Intravenous (IV) UST maintenance is explored as a solution.

Role of Mitochondria in Inflammatory Bowel Diseases: A Systematic Review.

Mitochondria are key cellular organelles whose main function is maintaining cell bioenergetics by producing ATP through oxidative phosphorylation. However, mitochondria are involved in a much higher number of cellular processes. Mitochondria are the home of key metabolic pathways like the tricarboxylic acid cycle and β-oxidation of fatty acids, as well as biosynthetic pathways of key products like nucleotides and amino acids, the control of the redox balance of the cell and detoxifying the cell from HS and NH.

Causality assessment methods in drug induced liver injury: strengths and weaknesses.

Diagnosis of drug-induced liver injury (DILI) remains a challenge and eagerly awaits the development of reliable hepatotoxicity biomarkers. Several methods have been developed in order to facilitate hepatotoxicity causality assessments. These methods can be divided into three categories: (1) expert judgement, (2) probabilistic approaches, and (3) algorithms or scales.

[Safety of conservative treatment of gastric perforation due to fish bone ingestion].

Intake of foreign bodies is the second most frequent indication for urgent upper gastrointestinal endoscopy. Once in the stomach, foreign bodies are usually spontaneously eliminated. However, a small percentage of large or sharp objects become stuck in the gastrointestinal mucosa.

[An analysis of the causes, characteristics, and consequences of reexposure to a drug or compound responsible for a hepatotoxicity event].

Introduction: reexposure to a causal agent represents a potentially serious event in hepatotoxicity.

Objectives: to assess the characteristics and outcome of cases with positive reexposure.

Material And Methods: a retrospective study of cases with evidence of positive reexposure included in Registro Español de Hepatopatías Asociadas a Medicamentos, and an analysis of their relation to demographic and clinical variables, causality, course, and consequences.

Assessment of drug-induced hepatotoxicity in clinical practice: a challenge for gastroenterologists.

Currently, pharmaceutical preparations are serious contributors to liver disease; hepatotoxicity ranking as the most frequent cause for acute liver failure and post-commercialization regulatory decisions. The diagnosis of hepatotoxicity remains a difficult task because of the lack of reliable markers for use in general clinical practice. To incriminate any given drug in an episode of liver dysfunction is a step-by-step process that requires a high degree of suspicion, compatible chronology, awareness of the drug's hepatotoxic potential, the exclusion of alternative causes of liver damage and the ability to detect the presence of subtle data that favors a toxic etiology.
