La vía de las lectinas en lupus y tuberculosis: polimorfismos de la MBL2 y MASP2, beneficiosos o perjudiciales/ The lectin pathway in lupus and tuberculosis: MBL2 and MASP2 polymorphisms, beneficial or harmful

[eng] MBL2 exon 1, promoter genotyping and serum MBL concentrations were determined in TB patients (79) and HHC (120) and in SLE cases (39) and controls (59). MASP-2 serum levels and 5 polymorphisms in MASP2 gene were also analyzed in 49 TB patients and 50 HHC and in the same SLE c...

Descripción
Sumario:&#091;eng&#093; MBL2 exon 1, promoter genotyping and serum MBL concentrations were determined in TB patients (79) and HHC (120) and in SLE cases (39) and controls (59). MASP-2 serum levels and 5 polymorphisms in MASP2 gene were also analyzed in 49 TB patients and 50 HHC and in the same SLE cases and controls as before. LXPA/HYPA, high MBL producer diplotype was significantly more frequent in HHC than in patients (16.8% vs 6.4%, p=0.03). Higher MBL levels were found in active TB than in HHC (median MBL 3420ng/mL &#091;10-28415&#093; and 2600 ng/mL &#091;5-20000&#093; respectively, p=0.02). In the SLE study LYQC/HYPD, LXPA/LYQC and LYPB/HYPD were only found in SLE patients, related to severe MBL deficiency (<100ng/mL). There was a strong correlation between MBL2 Exon 1 and promoter genotype and MBL levels. Asp105Gly MASP2 variant was the only detected among; no relationship was found between the variant and TB or SLE.
