Evaluation of pathogen specific urinary peptides in tick-borne illnesses.

Mass spectrometry enhanced by nanotechnology can achieve previously unattainable sensitivity for characterizing urinary pathogen-derived peptides. We utilized mass spectrometry enhanced by affinity hydrogel particles (analytical sensitivity = 2.5 pg/mL) to study tick pathogen-specific proteins shed in the urine of patients with (1) erythema migrans rash and acute symptoms, (2) post treatment Lyme disease syndrome (PTLDS), and (3) clinical suspicion of tick-borne illnesses (TBI).

Blastomycosis and human immunodeficiency virus: three new cases and review.

Reports of blastomycosis in individuals infected with the human immunodeficiency virus (HIV) are increasing. We report on 3 patients co-infected with blastomycosis and HIV (to add to the previously reported 21), and review important clinical aspects and outcomes in all cases. The percentage of patients co-infected with blastomycosis and HIV who had disseminated blastomycosis (63%) was similar to the blastomycosis patients in the general population (67%); however, as a group the patients with HIV were severely immunosuppressed and fared poorly.
