These findings suggest that macrolides may have a beneficial role in the treatment of chronic rhinosinusitis, particularly in patients with low levels of IgE, and supports the in vitro evidence of their antiinflammatory activity. Additional studies are required to assess their place in clinical practice.

Laparoscopic splenectomy is feasible in patients with giant spleens. However, it is associated with greater morbidity, and the advantages of minimal access surgery in this subgroup of patients are not so clear.

Macrolide antibiotics are capable of inhibiting pro-inflammatory cytokine production in vitro and are as potent as prednisolone. This mechanism is likely to be at least partly responsible for the clinical efficacy of macrolide antibiotics in chronic rhinosinusitis.

Now is an exciting era of development in immunotherapy checkpoint inhibitors and their effect on the treatment of NPC. While the general prognosis of R/M disease is poor, immunotherapy offers some promise in a malignancy associated with EBV and characterized by a peritumoural immune infiltrate. Our study aims to review past and on‐going clinical trials of monoclonal antibody therapies against the checkpoint inhibitors (e.g. PD1 and CTLA‐4), in R/M NPC. All randomized and nonrandomized controlled trials involving immune checkpoint inhibitor interventions for treatment of NPC were included in the study. We utilized a validated “risk of bias” tool to assess study quality. Four separate Phase I–II trials report the potential of PD1 inhibitor treatment for patients with NPC. Within the observed groups, camrelizumab combined with chemotherapy achieved an objective response in 91% of patients as first‐line treatment for metastatic NPC (PFS 68% at 1‐year) but this was associated with a high rate of grade >3 adverse events (87%; CTCAE version 4.03). The remaining three studies focused on recurrent NPC disease in patients who had received at least one line of prior chemotherapy. Within this group, camrelizumab monotherapy achieved an objective response in 34% of patients (PFS 27% at 1‐year; range across all three studies 20.5–34%). No NPC trial has yet reported on specific outcomes for non‐PD1 checkpoint inhibitors but 11 on‐going studies include alternative targets (e.g. PD‐L1/CTLA‐4) as combination or monotherapy treatments. In considering checkpoint immunotherapies for NPC, initial results show promise for anti‐PD1 interventions. Further phase I–III trials are in progress to clarify clinical outcomes, fully determine safety profiles, and optimize drug combinations and administration schedules.

Whilst elevation of a nasoseptal flap in endoscopic surgery of the anterior skull base engendered significant clinical deterioration on examination post-operatively, quality of life outcomes showed that no such deterioration was subjectively experienced by the patient. In fact, there was significant nasal airway improvement following nasoseptal flap reconstruction.

Long-term treatment of airway inflammation/infection with macrolide antibiotics has now been in use for almost 30 years. Whereas the beneficial clinical effect in cystic fibrosis and COPD have been backed up by randomized controlled trials, the evidence from the upper airways is not as strong. We have identified 22 open studies in chronic rhinosinusitis, with and without polyps, but only 2 randomized controlled trials. Of the controlled trials, the one including CRS patients just without polyps, showed a significant effect in sino-nasal outcome test, saccharine transit time, nasal endoscopy, and IL-8 levels in lavage fluid after 12 weeks of roxithromycin, whereas, in the other RCT with a mixed study group of CRS patients with and without polyps, 12 weeks of azithromycin showed no effect compared to placebo. Concerns regarding the risk of macrolides to induce arrhythmia have been raised. Recent FDA guidelines changes has recommended caution in patients with risk factors such as long QT syndrome, bradycardia, hypokalemia, or hypomagnesemia. Ototoxicity is another concern. Long-term macrolide antibiotics in the treatment of CRS patients is still a viable option in a select group of patients.
