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>

Individuazione e identificazione di una nuova variante emoglobinica durante la quantificazione dell’emoglobina glicata
Incidental detection of a new hemoglobin beta variant performing HbA1c measurement
<p>Incidental detection of a new hemoglobin beta variant performing HbA1c measurement. Hemoglobin &alpha; and &beta; chain variants can be incidentally detected during the glycated hemoglobin (HbA1c) determination. A 58-year-old female was investigated for HbA1c with Tera 3 Capillarys system (CE, Sebia). Quantification of HbA1c was invalidated by the presence of a double peak in the HbA0 zone. Standard high performance liquid chromatography (HPLC), performed with VARIANT IITM Analyzer (Biorad), did not separate the variant from Hb A0. &beta;-globin gene sequencing showed a heterozygous variation of nucleotide sequence HBB: c.376C&gt;A; beta 125 (H3) Pro&gt;Thr. The new variant, called Hb-Novara, was found also in the daughter of the proband, associated with an alpha-talassemic trait. The hemoglobin stability tests of both subjects were normal. A combination of different technologies (such as HPLC and CE) can be useful in the detection of new hemoglobin variants. Although Hb-Novara seems to be asymptomatic, it could produce relevant hematological phenotypes when associated with &alpha; or &beta; chain defects</p><p>&nbsp;</p>
