Plain English summary of protocol
Background and study aims
Pelvic inflammatory disease (PID) is caused by the spread of sexually transmitted infections from the vagina and cervix. If inadequately treated, PID can have serious consequences such as scarring of the fallopian tubes, which can lead to infertility, ectopic pregnancy and chronic pelvic pain. If taken correctly, a standard 14 days of antibiotic treatment has a cure rate of over 90%. However, because symptoms often improve within 7 days and antibiotics cause significant side effects, many women stop taking the medication early, thus the infection may not clear completely and may lead to further complications . The aim of this study is to simplify the standard antibiotic treatment for pelvic inflammatory disease (PID).
Who can participate?
Women who attend the genitourinary clinic with mild to moderate symptoms of PID (pain for less than 30 days)
What does the study involve?
Women are examined, have swabs taken to check for infection and are asked to fill in a questionnaire about pain and their beliefs around medicines. Women are then randomly allocated to either the standard of care (14 days of antibiotics) or the 5-day course of antibiotics. The women and research nurse know which antibiotics they are taking, but not the doctor. At follow-up in the clinic women are asked to complete a further questionnaire about pain, health beliefs, side effects and ability to take the tablets. The research nurse calls the women at 68 weeks for a final assessment, and where infection was found, invites women for repeat samples.
What are the possible benefits and risks of participating?
If a difference is found between the two antibiotic regimens in women with PID it will change the local treatment policies and so may improve future treatments for patients. There are no risks from any of the antibiotics; they are all used commonly for other conditions. All antibiotics can sometimes cause nausea, vomiting and rash but participants may not experience any side effects at all.
Where is the study run from?
This is a multi-centre study running in Brighton, London, Birmingham, Eastbourne/Hastings and Sheffield (UK).

| Scientific title | Is a short course of azithromycin effective in the treatment of mild to moderate pelvic inflammatory disease (PID)? |
| Study objectives | The aim of this study is to assess whether a shorter course of antibiotics taken over 5 days is as effective as the 14 day course and whether women find the shorter course more acceptable when compared to the current standard of treatment. |
