“…While the patient population that historically develops cryptococcal infections includes individuals with defects in CMI, patients with defects in antibody-mediated immunity (AMI) such as hypogammaglobulinemia and hyper-IgM syndrome also have an increased probability of developing cryptococcosis (Gupta et al, 1987; Iseki et al, 1994; Tabone et al, 1994; Casadevall, 1995; Antachopoulos et al, 2007).
