Abstract
Background: Distinct host immune status predisposes to different forms of pulmonary aspergillosis.
Methods: Patients with chronic cavitary pulmonary aspergillosis (CCPA; n=15) or allergic bronchopulmonary aspergillosis (ABPA; n=7) of Caucasian origin were screened for single nucleotide polymorphisms (SNPs) in the collagen region of surfactant proteins A1 (SP-A1) and A2 (SP-A2) and mannose binding lectin (MBL).
Results: The T allele at T1492C and G allele at G1649C of SP-A2 were observed at slightly higher frequencies in ABPA patients (86% and 93%) than in controls (63% and 83%), and the C alleles at position 1492 and 1649 were found in higher frequencies in CCPA patients (33% and 25%) than in ABPA patients (14% and 7%) (all p>0.05). However, the CC genotype at position 1649 of SP-A2 was significantly associated with CCPA (χ2=7.94; pcorr≤0.05). Similarly, ABPA patients showed a higher frequency of the TT genotype (71%) at 1492 of SP-A2 than controls (43%) and CCPA patients (41%) (p>0.05). In the case of MBL, the T allele (OR=3.1, range 1.2–8.9; p≤0.02) and CT genotype (χ2=6.54; pcorr≤0.05) at position 868 (codon 52) were significantly associated with CCPA, but not with ABPA. Further analysis of genotype combinations at position 1649 of SP-A2 and at 868 of MBL between patient groups showed that both CC/CC and CC/CT SP-A2/MBL were found only in CCPA patients, while GG/CT SP-A2/MBL was significantly higher in CCPA patients in comparison to ABPA patients (p≤0.05). SNPs analysed in SP-A1 did not differ between cases and controls.
Conclusions: Distinct alleles, genotypes and genotype combinations of SP-A2 and MBL may contribute to differential susceptibility of the host to CCPA or ABPA.
