All rapid responses
I applaud the attention being paid to UTI and the important observation by Gharbi et al that delayed treatment may cause unwanted consequences. I agree that it is important to respond AMR by rationalising the use of antibiotics. Pouwles et al, do well to raise the matter of treatment duration. However, I believe that the in our enthusiasm to address AMR we are failing in our responsibilities to a significant subset of exceptional patients. The key studies that drive the 3-day versus 14-day treatment were collated in an important meta-analysis by Milo et al (2005) . You have to go to the tables at the back of the full report and extract the data manually to learn that the trials recorded microbiological and symptomatic failure rates of between 28% and 37% of patients treated with 3 or 14 days of treatment. The MSU culture is promoted for UTI management despite it being discredited [2-5] with dipsticks found to be similarly flawed [6, 7]. In our enthusiasm for limiting antibiotic consumption we may be failing a significant minority. We dismiss their treatment response failures and persistent symptoms because negative results from discredited tests falsely reassure. We sentence these poor people to life-changing, painful chronic lower urinary tract symptoms, denying them legitimate treatment to comply with guidelines informed by dud tests. These are modern-day, sacrificial lambs, placed on the altar of the god of AMR. If you doubt this, pull out the Digital NHS data for hospital admissions and outpatient attendances for cystitis and interstitial cystitis and plot them on a time axis. Why do we see such a worrying rise in the number of cases?
