Short Cilia, Immunodeficiency, and Cystic Fibrosis in a Mother-Daughter Pair

Area of Science:

• Otolaryngology
• Genetics
• Immunology

Background:

• Chronic rhinosinusitis (CRS) refractory to maximal medical and surgical therapy necessitates investigation for underlying primary conditions.
• Cystic fibrosis (CF), primary immunodeficiency (PID), and primary ciliary dyskinesia (PCD) are recognized risk factors for refractory CRS, often presenting with delayed diagnosis in adulthood.
• These rare conditions can individually contribute to CRS persistence.

Purpose of the Study:

• To highlight the importance of evaluating patients with refractory CRS for underlying systemic disorders.
• To present a case study of a mother-daughter pair with refractory CRS exhibiting features of CF, PID, and PCD.
• To emphasize that refractory CRS can be multifactorial, stemming from a combination of risk factors.

Main Methods:

• Case report of a mother-daughter pair.
• Clinical evaluation for refractory chronic rhinosinusitis.
• Diagnostic workup for cystic fibrosis, primary immunodeficiency, and primary ciliary dyskinesia.

Main Results:

• The mother-daughter pair presented with CRS refractory to maximal medical management.
• Both patients exhibited clinical features consistent with cystic fibrosis, primary immunodeficiency, and primary ciliary dyskinesia.
• This case illustrates the potential for multiple rare disorders to coexist and contribute to refractory CRS.

Conclusions:

• Refractory CRS warrants thorough investigation to identify and manage potential underlying conditions such as CF, PID, and PCD.
• The co-occurrence of these rare disorders can lead to complex and persistent CRS.
• Comprehensive evaluation ensures appropriate management strategies for patients with challenging CRS cases.
