An immunodeficiency work up was performed (day +70 to +133), including HIV antigen/antibody, lymphocyte subsets (T-cells, B-cells, natural killer cells), immunoglobulin levels, complement levels, neutrophil oxidative burst assay, MBL level, anti-granulocyte-macrophage colony-stimulating factor (anti-GM CSF) autoantibodies, and Mendelian susceptibility to Mycobacterial disease panel: all were unremarkable, but MBL level was significantly low at 6 ng/ml. This evidence concerns the gene MBL2 and immunodeficiency disease.
