Health seeking behavior/illness was recorded and postwave serum samples measured for immunoglobulin (Ig) G to spike (S) (CoV2-S-IgG) by electrochemiluminescent immunosorbent assay. To estimate the protective CoV2-S-IgG threshold levels, logistic functions were fit to describe the correlation of CoV2-S-IgG measured before a wave and the probability for seroconversion/boosting thereafter.</div></div><div><h3>Results</h3><div>Despite little disease, 125 per 366 (34.2%) children (median age 6.7 years [interquartile range 5.99-7.4 years]) were seropositive after wave I, rising to 53.6%, 76.0%, and 96.2% and 99.2% after waves II (Beta), III (Delta), and IV and V (Omicron variants), respectively. CoV2-S-IgG induced by natural exposure protected against subsequent SARS-CoV-2 infection, with the greatest protection for Beta and least for Omicron. The levels of IgG specific for ancestral S antigen that provided a 50% protective threshold for the subsequent wave were lowest for the Beta and highest for the Omicron BA.1/BA.2 wave.

This study aimed to quantify adverse drug reactions (ADRs) to trimethoprim/sulfamethoxazole when used for treatment of melioidosis, and assess risk factors for ADR development. A retrospective review of antimicrobial associated ADRs was performed in all patients treated for melioidosis in the Northern Territory of Australia from January 2017-September 2022. Over this time, 268 treatment episodes from 256 individuals were included. The frequency of clinician-attributed ADRs to trimethoprim/sulfamethoxazole (51% of exposed) was higher than for other antimicrobials used (ceftazidime 12%, meropenem 8%, and doxycycline 12% of those exposed; <em>P</em> < 0.0001). 44% of those treated with trimethoprim/sulfamethoxazole required drug cessation or dose reduction and 5 individuals (2%) had a severe cutaneous adverse reaction, with one fatality. Acute kidney injury was the most frequent ADR (25% of those exposed), with age and pre-existing renal disease independently associated with its development. Here we report very high rates of ADRs attributed to trimethoprim/sulfamethoxazole resulting in frequent discontinuation of this drug as part of oral eradication therapy for melioidosis.
