Based on studies in Thailand and Taiwan, high-titers of anti-IFN-γ autoAb7 are present in 81% of patients with NTM (52 patients) and 96% of patients with other opportunistic infections with or without NTM (45 patients); neutralizing activity of these autoAbs was suggested as a parameter for monitoring of disease onset and progression. Here, IFNG is linked to Opportunistic infection.
