Is there any utility to trending Histoplasma serology titers to guide duration of therapy or treatment response for pulmonary histoplasmosis with negative urine antigen?

Serology unfortunately is not useful to monitor response to therapy as the fall in titers is often very slow. In immunocompetent individuals, titers will often take a few years to show a significant drop in the antibody titer after successful treatment. The treatment duration should be guided by the...
