Antibody deficiencies are more common in adult versus pediatric recurrent acute rhinosinusitis.

PURPOSE: To evaluate the frequency and types of humoral immunodeficiencies (HID) in pediatric and adult patients with recurrent (RARS). Patients with HID commonly present with upper respiratory tract infections. Their pathophysiology in children is different than adult counterparts. It is unknown how HID affects those two age groups. MATERIALS AND METHODS: We performed a retrospective chart review of pediatric (<18 years old) and adult (18 years and older) patients who were evaluated in our pediatric and adult rhinology clinic between July 2010 and December 2020 and had the diagnosis of recurrent (>3 times/year) rhinosinusitis. Patients with cystic fibrosis, Aspirin Exacerbated Respiratory Disease (AERD), and ciliary dyskinesia were excluded. Demographic data and associated conditions were reviewed. Immunologic evaluation included complete blood cell count (CBC) with differential, serum immunoglobulin G, A, and M levels, and baseline and post-vaccination pneumococcal antibody titers. RESULTS: There were 135 patients who met the inclusion criteria. 86 patients (63.7%) were children, 49 patients (36.3%) were adults. 46.5% of the pediatric patients and 45% of the adult patients were female. 17.4% of children had abnormal immunologic findings: 8 had hypogammaglobulinemia (p < 0.0001), 2 had specific antibody deficiency (SAD), and 5 had selective IgA deficiency. 32.7% of adults (p < 0.0001) had abnormal immunologic findings: 4 had hypogammaglobulinemia, 11 had SAD (p < 0.0001), and 1 patient had both IgA deficiency and SAD. CONCLUSION: Humoral immunodeficiency, specifically SAD, seems to be more common in adult versus pediatric RARS that is refractory to treatment.

Role of social determinants of health on quality of life in pediatric chronic rhinosinusitis.

KEY POINTS: Social determinants of health link to worse quality of life in pediatric chronic rhinosinusitis. The area deprivation index (ADI) may serve to predict health disparities in these patients.

Gender Differences in Quality of Life of Adolescent Patients With Chronic Rhinosinusitis.

OBJECTIVES: To identify the differences in the impact of chronic rhinosinusitis (CRS) between female and male adolescent patients at presentation. STUDY DESIGN: Cross sectional study. METHODS: Adolescent patients, age 12 to 18 years old, presenting to our Otolaryngology clinic between August 2020 and April 2023 for CRS were asked to fill both the SNOT-22 and the SN5 forms. Female and male cohorts were compared regarding their demographics, comorbidities, subjective and objective disease measurements, and choice of treatment. RESULTS: Sixty-six patients were included, 30 female and 36 male patients. There were no differences in age, allergic rhinitis, asthma, obstructive sleep apnea, presence of nasal septal deviation, and objective disease severity (P > .05 for all). At presentation, mean overall SNOT-22, ear/facial, sleep, and psychological domains were all higher in female patients (43vs 30.9, P = .02; 9.1vs 6, P = .03; 11.8vs 8.3, P = .07; 14.1vs 8.8, P = .02 respectively). SN5 scores and overall QoL visual analog scale were similar in females and males. CONCLUSION: Female patients with CRS show higher subjective disease burden. Incorporating data on gender-specific differences may be important to personalize treatment decision making.

Role of Acute Rhinosinusitis in Periorbital Infections in Children.

OBJECTIVE: Periorbital cellulitis in children are commonly caused by acute rhinosinusitis (ARS). This study investigated the association of ARS and the severity of periorbital cellulitis in children. STUDY DESIGN: Retrospective case-control study of children with periorbital cellulitis with ARS versus periorbital cellulitis without ARS. SETTING: Patients were seen at West Virginia University Children's Hospitals between August 2011 to August 2022. METHODS: Patients were divided into cases and controls based on presence or absence of ARS. ARS was defined based on clinical symptoms with objective presence of disease on CT scan. Patients' characteristics, treatment, hospital length of stay, and readmission were collected. RESULTS: The sample consisted of 118 pediatric patients with orbital cellulitis. Patients with ARS were younger than patients without ARS (6.3 vs 8.5, p = 0.025), however there were no sex differences between two groups (p = 0.540). The ARS group had higher incidence of postseptal cellulitis (51.5% vs 9.6%, p < 0.001). As compared to patients without ARS, patients with ARS were more likely to be admitted (p < 0.001), have a longer length of stay (median of 3.5 days vs 0.5 days, p < 0.001), require IV antibiotics (95.3% vs 54.9%, p < 0.001), and require surgical intervention (23.1% vs 5.8%, p < 0.001). Readmission rate was similar between the two groups. CONCLUSION: Children presenting with acute periorbital cellulitis who have ARS tend to have more severe infection requiring higher level of care. ARS should be assessed and incorporated into the plan of care of pediatric patients with periorbital infections.

Pediatric Rhinosinusitis.

Rhinosinusitis is a common diagnosis encountered by providers of all disciplines. Pediatric acute and chronic rhinosinusitis account for up to 2% of the total annual visits to the outpatient clinics and emergency departments. Once correct diagnosis is made, appropriate treatment measures can be initiated. It is important to recognize rhinosinusitis in children due to the potential serious complications and the impact it may have on quality of life of those children. Medical management is the mainstay of treatment, and, fortunately, it is successful in most of those children. When medical management fails, or a complication occurs, surgery may be required.

The immune system, the skin, and childhood rheumatic disease.

As the body's largest organ and first line of defense against the environment, the skin plays a vital role in host immune defense. In addition to its function as a physical barrier, the skin contains an active immune surveillance network and can mount highly specific responses to eliminate invading organisms. In this review, we discuss the functions of adhesion molecules in regulating the recruitment of distinct cell populations to skin in both healthy and disease states, and the interaction between innate and adaptive immune mechanisms active in the skin. We also review how these systems underlie the pathogenesis of skin manifestations of pediatric rheumatologic diseases.
