Assenza di bande monoclonali liquorali e positività del rispettivo indice siero-liquor: una discrepanza da indagare attenatamente
Absence of liquoral monoclonal bands and positivity of the respective serum-liquor index: an unespected findings to be carefully investigated
<p>A 13 year-old child whit headache, nausea and repeated episodes of vomiting was hospitalized at the Major Hospital of Charity of Novara. A lumbar puncture and biochemical investigations on cerebrospinal fluid (CSF) including oligoclonal bands (OCB) screen were performed. Kappa and Lambda free light chains (kFLC and &lambda;FLC) and IgG concentrations were measured in serum and CSF by nephelometry. OCB were evaluated by isoelectric focusing (IEF) followed by immunofixation (IMF). A negative IgG index, no OCB IgG (type I pattern), positive kFLC index with increased levels of kFLC (0.14 mg/dL) and &lambda;FLC (0.14 mg/dl in CSF) were found. The FLC data suggested an intrathecal synthesis. A CSF IMF was then performed using anti-IgM peroxidase together with the IgM index using Reiber&rsquo;s hyperbolyc graphic. The presence of a monoclonal IgM band and 76% of intrathecal IgM synthesis was demonstrated. A subsequent molecular biology investigation was performed on CSF and revealed a clear positivity for enterovirus.</p>
