Abstract

We measured soluble intercellular adhesion molecule-1 (sICAM-1) in the serum and cerebrospinal fluid (CSF) of 35 clinically active relapsing-remitting (RR) multiple sclerosis (MS) patients who underwent both lumbar puncture and gadopentetate dimeglumine (Gd-DTPA)-enhanced MRI within an interval of 1 week, and of 30 neurological controls of whom 17 had noninflammatory neurologic diseases (NIND), 8 bacterial meningitis (BM), and 5 AIDS dementia complex (ADC). Thirteen of the MS patients assumed corticosteroids at the time of the study. While sICAM-1 serum levels were highest in the BM group (p < 0.005), untreated MS patients showed levels higher (p < 0.05) than treated MS and NIND, but similar to ADC. Moreover, the untreated MS group had CSF/serum sICAM-1:CSF/serum albumin (sICAM-1 index) values higher than the treated group (p < 0.01), NIND (p < 0.005), and BM (p < 0.05); high sICAM-1 index was found also in ADC. Untreated MS patients with one or more Gd-DTPA-enhancing MRI lesions (Gd-positive) had higher mean values of CSF/serum albumin ratio (QAlbumin) and CSF mononuclear cells compared to patients without such lesions (Gd-negative). In the untreated Gd-negative patients, sICAM-1 serum levels were higher (p < 0.05) than those ...Continue Reading

Bacterial Meningitis (ASM)

Bacterial meningitis continues to be an important cause of mortality and morbidity throughout the world. Here is the latest research.

Blood Brain Barrier Regulation in Health & Disease

The blood brain barrier is essential in regulating the movement of molecules and substances in and out of the brain. Disruption to the blood brain barrier and changes in permeability allow pathogens and inflammatory molecules to cross the barrier and may play a part in the pathogenesis of neurodegenerative disorders. Here is the latest research in this field.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.
