Chronic rhinosinusitis (CRS) is a long-term sinus disease affecting 1 in 10 adults in the UK. Symptoms of CRS include a blocked and runny nose, loss of smell, facial pain, tiredness, and worsening of breathing problems such as asthma. Studies have shown that sinus disease can have a greater impact on quality of life than heart disease and back pain. The type of treatments given by GPs and Ear, Nose and Throat specialists in the NHS varies greatly. This is due to doctors currently having limited information on how to effectively treat patients with CRS due to a lack of clinical trials in this area. Intranasal medications like nasal steroid sprays/drops and saline rinses (irrigations) play an important role in helping to improve CRS symptoms, and have been shown to be effective in trials. Saline rinses help wash away any excess mucus or irritants inside the nose, which can reduce swelling and relieve symptoms. Nasal steroid sprays/drops help to reduce inflammation. Nasal steroids and saline rinses are considered “standard care”. Other treatments given may include further medications to reduce swelling, such as antibiotics, or operations such as endoscopic sinus surgery (ESS), but there are few trials comparing these with standard care. The aim of this study is to establish which treatments work best for adults with CRS with and without nasal polyps (abnormal growths).

Throughout the 6-month duration of the trial all participants are asked to use standard care (intranasal medications), which are considered the current best practice for management of CRS. This intranasal medication includes nasal steroid drops/sprays and saline rinses. Participants are randomly allocated to receive one of the three treatment options: intranasal medication plus clarithromycin capsules, intranasal medication plus placebo (dummy) capsules or intranasal medication plus ESS. Participants take two capsules every day for the first two weeks, and then a normal dose of one capsule a day for the next 10 weeks (3 months in total). ESS is an operation on the sinuses performed through the nostril and guided by a small camera. The surgeon removes any polyps if present and then opens each sinus that is blocked to allow drainage. Surgery is often performed as a day-case operation, but patients may need up to 10-14 days to recover fully from surgery. After 3 and 6 months the participants return to the outpatient clinic to see their doctor and/or research nurse and undergo assessments.

The researchers cannot guarantee that participating in this study will be of direct benefit. They hope to be able to improve the participants’ CRS symptoms, but the main benefit will be the information that they gather, which will help to improve treatment options for patients with CRS in the future. Participants will be closely followed up by their ENT doctor and the MACRO Research Team whilst participating in the trial. The most common side effects of clarithromycin are: abdominal pain, diarrhoea, nausea, vomiting, change in sense of taste, headache, insomnia, dyspepsia, rash, hyperhidrosis, and abnormal liver function test. These side effects are usually mild. Complications of sinus surgery include: bleeding (affects 1 in 200), infection (affects 1 in 15), minor bleeding into the eye socket which is seen as bruising around eye (affects 1 in 500), more serious bleeding into the eye socket (very rare), direct trauma to the orbital contents may cause double vision or in extremely rare cases loss of sight (affects <1 in 10,000), leak of brain fluid and possible risk of meningitis if leak is not sealed (affects 1 in 1500), deep vein thrombosis (DVT) (less than 1% chance), clot on lung (pulmonary embolism) (0.3% chance), damage to teeth (1 in 5000), and reaction to anaesthetic drugs e.g. rash, high temperature (1 in 10,000, mild, 1 in 200,000 severe).
