A total of 3825 patients with blastomycosis were identified. Of these, 41% experienced at least one missed diagnostic opportunity, with an average of 3.2 missed visits before diagnosis. The average diagnostic delay was 26.82 days (95% confidence interval: 24.57-28.96), with 17% of patients having delays lasting over a month. Missed opportunities occurred primarily in outpatient settings (59.4%). Risk factors for delayed diagnosis included history of diabetes, prior pulmonary conditions (e.g., chronic obstructive pulmonary disease), and respiratory therapies (e.g., antibiotics, inhalers). Diagnostic delays for blastomycosis are common. The association of delays with pre-existing pulmonary conditions underscore the need for heightened clinical suspicion in patients with respiratory symptoms.

We investigated plasma ACAA profiles and function in a cross-sectional Vietnamese cohort stratified by HIV and CM status (n = 20 per group). We quantified plasma ACAAs against interferons (IFNs), interleukins (ILs), and granulocyte-macrophage colony-stimulating factor (GM-CSF) using a particle-based assay, and assessed their neutralizing activity in high-titer samples. Associations between ACAA levels and CM were analyzed using Firth-penalized logistic regression, adjusting for age, sex, and CD4 count (in HIV-positive models). In HIV-negative individuals, higher anti-GM-CSF levels were associated with CM (odds ratio [OR] per log-unit increase, 1.84; 95% confidence interval [CI], 1.07-3.18). This association was predominantly observed in Cryptococcus gattii cases and was accompanied by functional neutralizing activity. Furthermore, adding pre-specified plasma IgG2 improved overall model fit and showed a strong inverse association with CM (OR, 0.03; 95% CI, 0.003-0.29). Conversely, HIV-positive CM cases had lower overall ACAA levels than non-CM controls. After adjusting for hypogammaglobulinemia/IgG1, significant inverse associations persisted for anti-IL-10, anti-IL-12, anti-IL-15, and anti-IL-22 with CM status. Type I IFN-binding ACAAs were largely non-neutralizing. These findings reveal distinct pathogenic mechanisms. In HIV-negative CM, neutralizing anti-GM-CSF antibodies, often in C. gattii infection, and low IgG2 were independently associated with disease. In HIV-positive CM, ACAA reductions without cytokine neutralization may reflect underlying antibody and/or B-cell deficiency.
