Kappa Index versus CSF Oligoclonal Bands in Predicting Multiple Sclerosis and Infectious/Inflammatory CNS Disorders [PDF]

Diagnostics, 2020
Background: Cerebrospinal fluid (CSF) kappa free light chains (KFLC) are gaining increasing interest as markers of intrathecal immunoglobulin synthesis. The main aim of this study was to assess the diagnostic accuracy (AUC) of the kappa index (CSF/serum ...

Elevated Kappa Index in the Absence of Cerebrospinal Fluid IgG Oligoclonal Bands: Contribution of Intrathecal IgM and IgA Synthesis [PDF]

Biomolecules
The kappa index is a well-established marker of intrathecal synthesis (IS) of immunoglobulin (Ig). Routinely used for diagnostic aims, IgG IS, which can be assessed quantitatively (ad hoc formulas) or qualitatively (oligoclonal bands, OCBs), may fail in ...

Kappa free light chains index in multiple sclerosis very long-term prognosis

Frontiers in Immunology, 2023
IntroductionThe role of the kappa-free light chain (kFLC) in the diagnosis of multiple sclerosis (MS) and, to a lesser extent, its role as a medium-term prognostic marker have been extensively studied.

Optimized Kappa-Index Test Protocol to Detect Intrathecal Immunoglobulin Synthesis in Multiple Sclerosis. [PDF]

Eur J Neurol
ABSTRACT Background Kappa free light chain (KFLC)‐based Kappa‐index (K‐index) can substitute oligoclonal banding (OCB) to detect intrathecal immunoglobulin synthesis. Cutoffs for positive results vary; therefore, further comparison of different approaches is necessary to optimize K‐index for ...

Concordance rate between oligoclonal bands and the Kappa index in patients with suspected multiple sclerosis (MS). [PDF]

Arq Neuropsiquiatr
Abstract Background Oligoclonal bands (OCBs) and Kappa free light chains (FLCs) in the cerebrospinal fluid (CSF) are sensitive markers of intrathecal immunoglobulin (Ig)G synthesis in patients with multiple sclerosis. Objective To evaluate the concordance rate between OCBCs and the Kappa index (KI) in patients with suspected multiple

A CORRELATION BETWEEN THE KAPPA NUMBER AND THE VENTORIM INDEX IN THE BLEACHING PROCESS [PDF]

Revista Árvore
The determination of the kappa number in the bleaching process is typically conducted with a pulp quantity between 3 and 4 grams, allowing for the calculation of values above four. However, after the oxidative extraction stage with hydrogen peroxide, the
