MBL serum levels and function are genetically determined, but levels rise during inflammation. We address the relative frequency of deficient genotypes, the relationship between serum level and genotype and both age and disease manifestations in patients with chronic pulmonary (CPA) and allergic bronchopulmonary aspergillosis (ABPA) and severe asthma with fungal sensitization (SAFS). DNA was extracted from blood samples, and <jats:italic>MBL2<\/jats:italic> genotyping was performed using the INNO\u2010LiPA <jats:italic>MBL2<\/jats:italic> kit. Serum MBL concentrations were determined using ELISA. One hundred and eight patients were evaluated, 70 (65%) with CPA, 38 (35%) with allergic disease (ABPA, SAFS or undefined) and 13 (12%) had both CPA and ABPA. The mean MBL serum level was 1849\u2003\u03bcg\u2003L<jats:sup>\u22121<\/jats:sup> and did not differ between groups. Forty subjects (37%) had exon 1 genotypes producing nonfunctional MBL (A\/B, A\/C, A\/D and O\/O), a frequency not different from published normal controls. A\/A subjects with CPA had higher levels (2981\u2003\u03bcg\u2003L<jats:sup>\u22121<\/jats:sup>) compared with allergic A\/A subjects (2202\u2003\u03bcg\u2003L<jats:sup>\u22121<\/jats:sup>) (pc0.012). No single haplotype, genotype or allele was significantly related to any aspergillosis phenotype. Worse breathlessness was associated with higher MBL levels among A\/A subjects (<jats:italic>P<\/jats:italic>\u2003=\u20030.009) and conversely nonfunctional genotypes. Mean MBL values were higher in those with an Medical Research Council (MRC) breathlessness score of 5 compared with those with and MRC score of 1 (<jats:italic>P<\/jats:italic>\u2003=\u20030.023). A\/A allergic subjects (<jats:italic>n<\/jats:italic>\u2003=\u200327) in this study were \u223c11\u2003years younger than allergic A\/O subjects (<jats:italic>n<\/jats:italic>\u2003=\u200311, <jats:italic>P<\/jats:italic>\u2003=\u20030.02). Subjects with worse respiratory status or more severe CPA had higher MBL serum levels (<jats:italic>P<\/jats:italic>\u2003=\u20030.023; <jats:italic>P<\/jats:italic>\u2003=\u20030.034). Bronchiectasis was not associated with MBL levels in CPA or allergic aspergillosis.
