---|---|---|---|---|
Primary | Change in numbers of M. pneumoniae-specific ASCs and M. pneumoniae-specific INF-?-secreting T cells in blood from inclusion (day 0) to 1-month follow-up (day 28) | Enzyme-linked immunospot (ELISpot) assay and flow cytometry | At day 0 (inclusion, disease presentation) and at day 28 (follow-up, disease resolution) | |
Secondary | Change in M. pneumoniae DNA levels in respiratory samples from inclusion (day 0) to 1-month follow-up (day 28) | PCR | At day 0 (inclusion, disease presentation) and at day 28 (follow-up, disease resolution) | |
Secondary | Change in total and M. pneumoniae-specific antibody levels (immunoglobulin (Ig)G, IgM, IgA) from inclusion (day 0) to 1-month follow-up (day 28) | Enzyme-linked immunosorbent assay (ELISA) | At day 0 (inclusion, disease presentation) and at day 28 (follow-up, disease resolution) | |
Secondary | Outcome of community-acquired pneumonia (CAP) assessed by clinical assessment of body temperature (°C) and respiratory rate (per minute) at 1-month follow-up (day 28) | Clinical assessment of body temperature (°C) and respiratory rate (per minute), with worse outcome defined as body temperature more than 38.5°C and respiratory rate according to age more than 40/min for 3 years, more than 34/min for 4-5 years, more than 30/min for 6-12 years, and more than 16/min for 13-18 years. | At day 28 (follow-up) |
