Summary

Chronic rhinosinusitis (CRS) is a disease associated with impaired quality of life and substantial societal costs. Though sometimes co-appearing with other conditions, such as asthma, allergy, and nasal polyps, many cases present without co-morbidities. Micro-biological diagnostic procedures are frequently undertaken, but the results are often inconclusive. Nevertheless, antibiotics are usually prescribed, but invariably with limited and temporary success. Accordingly, there is a need for new treatments for CRS.

Recent studies indicate that the sinuses are colonized by a commensal microbiome of bacteria and that damage to this natural microbiome, by pathogens or antibiotics, may cause an imbalance that may promote CRS. Therefore, treatments that restore the commensal microbiome may offer an alternative to current protocols. Arguably, as suggested by studies on patients with intestinal infections (next paragraph), one such possibility may be to transfer a "normal microbiome" to patients with CRS.

A disrupted microbiome is linked to intestinal clostridium difficile infections. Probiotic restitution therapy may be effective even in cases recalcitrant to antibiotic treatment. However, a key to effective probiotic restitution is selecting the bacteria that facilitate regrowth of normal microbiome. As an answer to this, researchers have chosen to simply transplant the entire microbiome from a healthy donor. In the case of clostridium difficile infection in the form of faecal transplants.

In this study, we will examine the possibility to treat patients with chronic rhinosinusitis without polyps (CRSsNP) with complete sinonasal microbiomes obtained from healthy donors. Our analysis will focus on symptoms and signs of disease as well as on nasal inflammatory and microbiological indices.
