Evaluation and treatment of rhinosinusitis with primary antibody deficiency in adults: Evidence-based review with recommendations

BACKGROUND

There is clear evidence that the prevalence of primary antibody deficiency (PAD) is higher in patients with recurrent and chronic rhinosinusitis (CRS) than in the general population. The purpose of this multi-institutional and multidisciplinary evidence-based review with recommendations (EBRR) is to thoroughly review the literature on rhinosinusitis with PAD, summarize the existing evidence, and provide recommendations on the evaluation and management of rhinosinusitis in patients with PAD.

METHODS

The PubMed, EMBASE, and Cochrane databases were systematically reviewed from inception through August 2022. Studies on the evaluation and management of rhinosinusitis in PAD patients were included. An iterative review process was utilized in accordance with EBRR guidelines. Levels of evidence and recommendations on the evaluation and management principles for PAD were generated.

RESULTS

A total of 42 studies were included in this evidence-based review. These studies were evaluated on incidence of PAD in rhinosinusitis patients, incidence of rhinosinusitis in PAD patients, and on the different treatment modalities used and their outcome. The aggregate quality of evidence was varied across reviewed domains.

CONCLUSION

Based on the currently available evidence, PAD can occur in up to 50% of patients with recalcitrant CRS. Despite the presence of multiple studies addressing rhinosinusitis and PAD, the level of evidence supporting different treatment options continues to be lacking. Optimal management requires a multidisciplinary approach through collaboration with clinical immunology. There is need for higher-level studies that compare different treatments in patients with PAD and rhinosinusitis.

International consensus statement on allergy and rhinology: rhinosinusitis 2021

I.

EXECUTIVE SUMMARY

BACKGROUND: The 5 years since the publication of the first International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR-RS) has witnessed foundational progress in our understanding and treatment of rhinologic disease. These advances are reflected within the more than 40 new topics covered within the ICAR-RS-2021 as well as updates to the original 140 topics. This executive summary consolidates the evidence-based findings of the document.

METHODS

ICAR-RS presents over 180 topics in the forms of evidence-based reviews with recommendations (EBRRs), evidence-based reviews, and literature reviews. The highest grade structured recommendations of the EBRR sections are summarized in this executive summary.

RESULTS

ICAR-RS-2021 covers 22 topics regarding the medical management of RS, which are grade A/B and are presented in the executive summary. Additionally, 4 topics regarding the surgical management of RS are grade A/B and are presented in the executive summary. Finally, a comprehensive evidence-based management algorithm is provided.

CONCLUSION

This ICAR-RS-2021 executive summary provides a compilation of the evidence-based recommendations for medical and surgical treatment of the most common forms of RS.

Primary immunodeficiency and recalcitrant chronic sinusitis: a systematic review

BACKGROUND

A subset of patients with chronic rhinosinusitis (CRS) has disease refractory to standard therapies. Primary immunodeficiency should be considered in this group. Past literature has demonstrated an association between immunodeficiency and chronic sinusitis.

METHODS

A systematic literature search was performed using OVID, MEDLINE, EMBASE, and Cochrane databases to identify English language papers containing original human data on subjects with primary immunodeficiency and chronic sinusitis. A total of 39 studies met inclusion criteria. Data was collected pertaining to immune dysfunction in patients with chronic sinusitis, the clinical workup for these patients, and the effectiveness of medical and surgical treatments. The studies were assessed to determine their level of evidence.

RESULTS

The majority of studies were supported by Level 4 evidence. Up to 50% of patients with recalcitrant CRS were found to have immune dysfunction. The most frequent primary immunodeficiencies studied were common variable immunodeficiency (CVID) and X-linked agammaglobulinemia (XLA). Common collected data included measurement of serum immunoglobulins and functional antibody responses. Treatments reviewed include immunoglobulin replacement, long-term antibiotics and endoscopic sinus surgery.

CONCLUSION

Patients with recalcitrant CRS should be evaluated for primary immunodeficiency. This should include as assessment of quantitative serum immunoglobulin levels as well as functional antibody responses. Medical therapy, particularly immunoglobulin replacement therapy, appears to be most effective when administered at high doses early in the disease course. The addition of surgery is less clearly supported, but may also provide benefit if performed early.

Pulmonary and sinusal changes in 45 patients with primary immunodeficiencies: computed tomography evaluation

OBJECTIVE

The aims of the study were 1) to identify and quantify pulmonary changes in subjects affected by agammaglobulinemia (AG), and common variable immunodeficiency (CVID) and 2) to assess the incidence, type, and degree of chronic sinusitis and their relation to pulmonary changes.

METHODS

Forty-five patients affected by AG (18) and CVID (27) underwent computed tomography of lungs and paranasal sinuses.

RESULTS

Of 45 patients, 26 (57.7%) had pulmonary changes, more frequent among CVID than AG patients (P = 0.37). Bronchiectases were detected in 7 of 12 AG and in 9 of 14 CVID; the difference is not statistically significant (P = 0.53). Computed tomographic findings of chronic sinusitis were detected in 41 of 45 patients. There was no statistically significant difference between AG and CVID patients. Bronchial and sinusal abnormalities did not correlate in 11 patients followed longitudinally.

CONCLUSIONS

On computed tomography, the type and severity of lung lesions do not correlate either with the type of immunodeficiency or with the severity of the sinusal involvement.
