Evaluation of the diagnostic performance of a semi-quantitative lateral flow assay for the detection of Cryptococcus antigen in serum and cerebrospinal fluid specimens.

Cryptococcosis predominantly affects immunocompromised individuals, particularly those with advanced HIV disease, with meningitis being the most severe form and linked to high mortality. Diagnosis typically relies on rapid Cryptococcus antigen (CrAg) testing, and antigen titer quantification helps in early detection and assessing disease severity. However, conventional titer methods are often more expensive than qualitative antigen detection.

Exploratory analysis of the economically justifiable price of tezepelumab for asthma severe in Colombia.

Introduction: Asthma severe imposes important economic burden on health systems, especially with the incorporation of new drugs. Recently, tezepelumab has been approved to prevent exacerbations in patients. This study explores the economically justifiable price of tezepelumab for preventing exacerbations in patients with severe asthma.

Efficient use of mepolizumab in children: An analysis of the economically justifiable price in Colombia.

Introduction: Asthma imposes a crucial economic burden on health systems, especially with the incorporation of new drugs. Recently, mepolizumab has been approved to prevent exacerbations in patients with eosinophilic asthma. This study explores the economically justifiable price of mepolizumab for preventing exacerbations in children with severe asthma.

Tuberculosis in otherwise healthy adults with inherited TNF deficiency.

Severe defects in human IFNγ immunity predispose individuals to both Bacillus Calmette-Guérin disease and tuberculosis, whereas milder defects predispose only to tuberculosis. Here we report two adults with recurrent pulmonary tuberculosis who are homozygous for a private loss-of-function TNF variant. Neither has any other clinical phenotype and both mount normal clinical and biological inflammatory responses.
