Fully-automated assay by liquid chromatography for routine drug monitoring in body fluids--method development with biological samples.

J Pharm Biomed Anal

Department of Biochemistry, Dr. K. Thomae GmbH, Postfach 17 55, 7950 Biberach, FRG.

Published: April 2008

A fully-automated liquid chromatograph based on alternated pre-column enrichment technique has been developed for routine drug monitoring of body fluids using a column switching technique. Advantages of the method include the facility of direct injection of the body fluid onto the chromatograph and the simultaneous detection of both polar and non-polar metabolites under isocratic or gradient elution conditions.

Department of Endocrinology, Metabolism, and Diabetes, Istanbul University-Cerrahpasa, Istanbul, Turkey.

Background: The coexistence of primary glomerulonephritis and autoimmune thyroid disease has not been investigated.

Objective: This study aimed to assess thyroid morphology using sonography, determine the prevalence of autoimmune thyroid disorders, and evaluate thyroid function status in patients diagnosed with primary glomerulonephritis.

Materials And Methods: This single-center cross-sectional and observational study included 58 consecutive patients with primary glomerulonephritis and 58 healthy controls (HC).

Eczematous paradoxical reactions are commonly associated with anti-interleukin-17A (anti-IL-17A) antibodies. However, IL-23 p19 inhibitors can also cause similar cutaneous manifestations. We present a case of a 77-year-old Japanese woman with palmoplantar pustulosis (PPP), who developed eczematous lesions on her face, neck, and dorsum of the hands 10 weeks after initiating guselkumab treatment.

Background: Catechol-O-methyl transferase (COMT) inhibitors are routinely used to manage motor fluctuations in Parkinson's disease (PD). We assessed the effect of opicapone on motor symptom severity in levodopa-treated patients without motor complications.

Methods: This was a randomized, double-blind, 24-week, placebo-controlled study of opicapone 50 mg as adjunct to levodopa (NCT04978597).

Metagenomic analysis identifying a polymicrobial pulmonary infection in a non-HIV immunocompromised patient: a case report.

BMC Pulm Med

January 2025

Central Laboratory, Liaocheng People's Hospital and Liaocheng School of Clinical Medicine, Shandong First Medical University, Liaocheng, Shandong, 252000, China.

Background: Polymicrobial pulmonary infections, common in immunocompromised patients, often manifest more severe symptoms than monomicrobial infections. Clinical diagnosis delays may lead to mortality, emphasizing the importance of fast and accurate diagnosis for these patients. Metagenomic next-generation sequencing (mNGS), as an unbiased method capable of detecting all microbes, is a valuable tool to identify pathogens, particularly in cases where infections are difficult to diagnosis using conventional methods.

Background: Paliperidone is a second-generation antipsychotic and the main active metabolite of risperidone, formulated to provide consistent therapeutic effects through an extended-release system, designed to provide consistent therapeutic effects through an extended-release formulation. While commonly used in clinical practice, switching from risperidone to paliperidone, particularly during valproate therapy, can pose challenges due to potential pharmacokinetic interactions that may increase the risk of extrapyramidal symptoms (EPS). Despite clinical observations suggesting these interactions, case reports documenting such adverse effects are scarce.
