Primary endoscopic endonasal dacryocystorhinostomy for pediatric nasolacrimal duct obstruction: A systematic review

Saniasiaya J, Abdullah B, Husain S, Wang Y, Wan Mohammad Z

Am J Rhinol Allergy, 2017 Sep 01;31(5):328-333.
PMID: 28859711 DOI: 10.2500/ajra.2017.31.4464

BACKGROUND: Epiphora secondary to nasolacrimal duct obstruction is common in the pediatric age group. The mainstay treatment among these young patients has been conservative. Once epiphora becomes recalcitrant, however, an external or an endonasal approach is considered.
OBJECTIVE: Endoscopic dacryocystorhinostomy (EDCR) entails creating an opening from the lacrimal sac directly into the nasal cavity to counteract nasolacrimal duct obstruction. We reviewed the literature to determine the effectiveness and the safety of primary EDCR to treat pediatric nasolacrimal duct obstruction.
METHOD: A literature search was conducted by using a number of medical literature data bases for the period from 1995 to 2016. The following search words were used either individually or in combination: epiphora, nasolacrimal duct obstruction, endoscopic dacryocystorhinostomy, powered endoscopic dacryocystorhinostomy, laser-assisted endoscopic dacryocystorhinostomy, children, congenital, acquired, presaccal obstruction, and postsaccal obstruction. In addition, a few articles were identified based on the experience and information provided by the senior authors (B.A., S.H., D.Y.W.). The search was conducted over a 1-month period (January 2017). Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Cochrane Handbook for Systematic Reviews of Interventions were followed when possible.
RESULTS: Only 10 original clinical research articles were selected based on our objectives and selection criteria. All the studies were at level of evidence III: nonrandomized and noncomparative prospective or retrospective case series. Altogether, 313 patients with ages that ranged from 4 months to 18 years were enrolled. A total of 352 EDCRs were performed that were either single sided (n = 313) or bilateral (n = 39). The most common causes of the obstruction were classified as congenital, followed by idiopathic, and then acquired. A meta-analysis was not performed because of the heterogeneity of the patient groups and variability of the methods used to measure outcomes.
CONCLUSION: Analysis of the results indicated that EDCR was an effective, safe therapeutic approach to treating nasolacrimal duct obstruction in pediatric patients. It should be considered as an alternative procedure to external dacryocystorhinostomy after a failed conservative treatment.
Fulltext Nasal Septal Ancient Schwannoma: Ancient and Rare

Venkatasamy R, Mohan Singh AS, Arasu K, Husain S, Mianxin C

Schwannoma is a rare benign neurogenic tumor arising from the Schwann cells of peripheral nerves. A 77-year-old man presented with progressively worsening left nasal block and hyposmia for the past six months. Nasal endoscopy revealed a polypoidal reddish mass occupying the left middle meatus. The biopsy was in favor of ancient schwannoma. Endoscopic transnasal excision of the mass arising from the left nasal septum was performed. A middle meatal antrostomy was also performed. The tumor cells were positive for S100 protein. Presenting symptoms are common to other sinonasal tumors, and the differential diagnoses include carcinoma, inverted papilloma, sarcoma, lymphoma, and neurofibroma. Schwannomas are composed of spindle cells with two histologically distinct patterns that can be mixed: Antoni type A and Antoni type B. A neural crest marker antigen, S-100 protein, is useful to corroborate our diagnosis. It is vital to consider nasal septal schwannoma in the differential diagnosis of patients complaining of unilateral nasal obstruction with polypoidal nasal mass, especially the posterior third of the nasal septum. Transnasal endoscopic surgery is the preferred approach for nasal septal schwannoma.

PMID: 37407235 DOI: 10.1136/bcr-2022-251801

Rosai-Dorfman disease (RDD) is a rare and benign lymphoproliferative disorder that commonly presents as painless, bilateral neck swelling. Extranodal presentations are considered rare, but the most common extranodal locations involved include skin, subcutaneous followed by nasal/paranasal sinuses. Although it is a benign condition, it may be mistaken as a malignant lesion and requires a biopsy for diagnostic confirmation. In this study, we report a rare case of RDD with bilateral neck node and nasal/paranasal sinus involvement which initially presented with bilateral nasal obstruction. And, we reviewed the management in this unusual case and discussed the helpful role imaging studies play in the further workup and subsequent follow-up to treatment response.

Husain S, Hamid IA, Zahedi FD, Hamizan AKW

Saudi Med J, 2021 Nov;42(11):1209-1216.
PMID: 34732553 DOI: 10.15537/smj.2021.42.11.20210529

OBJECTIVES: To assess olfactory abilities using a culturally adapted Sniffin' Sticks smell test in different age groups.
METHODS: This was a cross-sectional study, conducted at Otorhinolaryngology outpatient clinic of Universiti Kebangsaan Malaysia Medical Centre, Secondary Science School, and Children Learning Centre in Kuala Lumpur, Malaysia, from August 2019 until December 2021.
RESULTS: In 450 healthy participants, the cut-off points of the threshold discrimination identification (TDI) scores at the 10th percentile for olfactory abilities were 19 in children, 30.1 in adolescents, 32.1 in young adults, 31.1 in middle-aged adults, and 28.6 in older adults. The children had significantly lower olfactory abilities, with the Bonferroni post-hoc tests of p<0.001. The young adults had higher olfactory abilities than older adults (p<0.05). The results showed that the identification score was highest in middle-aged adults (p<0.001). The discrimination score was the highest in young adults (p<0.001). The best odor threshold performance was observed in adolescents (p<0.001). The TDI score showed a significant difference in olfactory abilities between men and women (p=0.001).
CONCLUSION: Using a culturally adapted smell test, our population was able to identify, discriminate, and perceive odorants better than the European population. This data will help clinicians and researchers with a tool to reliably establish the correct results of olfactory function in our population. Women had better olfactory abilities than men.
Homology modeling of human BAP1 and analysis of its binding properties through molecular docking and molecular dynamics simulation

BRCA1-associated protein 1 (BAP1) is a nuclear-localized Ubiquitin C-terminal hydrolase (UCH) that functions as a tumour suppressor, and although BAP1 has been linked to cancer, the molecular mechanism by which BAP1 regulates cancer and its crystal structure have not been elucidated. In this study, computational approaches were used to identify the protein model of BAP1 and its potential inhibitors. The structure of the BAP1 model was constructed through homology modeling and the generated BAP1 model was observed to exhibit good quality protein model as the distribution of its amino acids in the Ramachandran's plot corresponded to 87.7% in the most favoured regions. Docking and simulating of the ubiquitin on the BAP1 model structure revealed the rearrangement of F228, F50, and H169 residues of the BAP1 and switching of BAP1's conformation into a productive state. Our screening results of potential BAP1 inhibitors against the FDA approved drugs shortlisted two potential inhibitors, which are FDA1065 and FDA755. We then performed molecular dynamics simulations and Molecular mechanics Poisson-Boltzmann surface area (MMPBSA) analysis on both inhibitors and found that only the BAP1-FDA755 formed a stable complex and the FDA755 ligand remained its position inside the active site of the BAP1 with a total binding energy of (-51.77 ± 3.49 kcal/mol). We speculate that the presence of methyl group in FDA755 play an important role in stabilizing the BAP1-FDA755 complex.Communicated by Ramaswamy H. Sarma.
Fulltext Sphenoid Lymphoma: A Diagnostic Challenge

Suthersan S, Periasamy C, Noh KB, Lee SK, Husain S

Cureus, 2023 Jun;15(6):e41058.
PMID: 37519496 DOI: 10.7759/cureus.41058

Sphenoid sinus lesions grasp the attention of Otorhinolaryngologists due to their prime location and vital surrounding structures. Once detected, these lesions require prompt investigation to identify the underlying cause, usually attributed to a tumor, fungal infection, sinusitis, or polyps, thus allowing tailored treatment. We report a case of an elderly lady whose neurological presentation lead to the diagnosis of sphenoid sinus lymphoma. We discuss the diagnostic challenge in view of its interesting presenting symptoms as well as the surgical approach risk and limitations.

Zahedi FD, Asmi NH, Husain S, Gendeh BS

Indian J Otolaryngol Head Neck Surg, 2019 Nov;71(Suppl 3):1837-1842.
PMID: 31763256 DOI: 10.1007/s12070-017-1219-x

Nasal irrigation is an effective and cheap method in managing post sinonasal surgery patients. It works by improving ciliary clearance and performing mechanical debridement of the thick crust, decreasing mucosal edema and reducing the inflammatory mediators. Presence of nasal irrigation bottle contamination and its effect on patients have been studied. The aim of this study is to prospectively identify the risk of contamination in the nasal irrigation bottle, fluid from the bottle and to correlate with endoscopic findings from the patients who had underwent sinonasal surgery. Swabs will be taken from the nasal irrigation bottle and patient's middle meatus before the surgery and at each post surgery visits (2 and 4 weeks). Patients will be advised to irrigate their nose three times per day post sinonasal surgery. During endoscopic examination of the patient's nasal cavity at 2 and 4 weeks, any evidence of infection will be noted and documented. Additionally, a swab of fluid irrigated from the nasal cavity collected during the clinic follow-ups will also be taken. The specimens will be sent to the Microbiology laboratory for standard culture and sensitivity test. A total of 27 patients completed the study and were divided into case (n = 15) and control (n = 12) groups. The CFU (colony-forming unit) value of the bacteria cultured from the nasal cavity and the nasal irrigation bottle was statistically significantly (P = 0.00) increased from the baseline to the second week follow-up in both groups but not from the second week to the fourth week follow-up. The majority of the swabs from the nasal cavity of the patients and the nasal irrigation bottles were positively cultured for Pseudomonas sp. group. Other groups of bacteria that were cultured were Enterobacter sp., Coagulase Negative Staphylococcus (CONS) and Klebsiella sp. Endoscopically, there was no clinical evidence of infection found in the nasal cavity of the patients. The nasal irrigation bottle that was used in the post sinonasal surgery treatment and for alleviation of symptoms of sinonasal diseases was found to have bacterial contamination from the swabs taken from the bottle. However, despite this finding there was not clinical evidence of infection noted from the nasal endoscopic examination. A simple and effective method of cleaning the bottle would be helpful to reduce the bacterial contamination for this useful treatment method.
Fulltext Challenges in Managing Intractable Epistaxis in a Post-nasal Surgery and Radiated Cancer Patient: A Case Report and Literature Review

Goh SP, Wilfred R, Husain S, Tang IP

Indian J Otolaryngol Head Neck Surg, 2023 Apr;75(Suppl 1):1096-1100.
PMID: 37206815 DOI: 10.1007/s12070-023-03625-4

Recurrent epistaxis represents an alarming sign that may suggest a sinister aetiology, especially in patients with previous head and neck malignancy. The recognition of certain potentially life-threatening conditions, namely pseudoaneurysm or tumour recurrence, remains prudence to avoid disastrous repercussion. Nasal endoscopy has become an essential tool in otolaryngology. It can aid identify the underlying cause of epistasis and facilitate therapeutic management. On the other hand, radio imaging is highly sensitive in detecting vascular lesions, besides providing a pre-operative mapping if surgical intervention is planned. This paper reported a patient with sphenoidal sinus squamous cell carcinoma in remission presented with torrential epistaxis not relieved with nasal packing. Despite a repeated angiogram and magnetic resonance image, the identification of the source of bleeding remained futile, culminating in an examination under general anaesthesia. The diagnosis of carotid blowout syndrome was made intraoperatively, and the bleeding was temporarily secured with a muscular patch, preceded by the insertion of a vascular stent. The authors wish to highlight the importance of examination under general anaesthesia if radio imaging does not correlate to the clinical findings. Management options for carotid blowout should be tailored to the patients' medical conditions.

Fulltext Efficacy of mometasone furoate and fluticasone furoate on persistent allergic rhinoconjunctivitis

Aneeza WH, Husain S, Rahman RA, Van Dort D, Abdullah A, Gendeh BS

Allergy Rhinol (Providence), 2013;4(3):e120-6.
PMID: 24498516 DOI: 10.2500/ar.2013.4.0065

Allergic rhinoconjunctivitis denotes both nasal and ocular manifestation of allergy, which may be solely treated with intranasal steroid. This study compares the efficacy of mometasone furoate nasal spray (NS) and fluticasone furoate NS in treatment of allergic rhinoconjunctivitis. The secondary objective is to study the severity of baseline ocular symptoms in allergic rhinoconjunctivitis. Seventy-eight patients with allergic rhinoconjunctivitis were assessed subjectively and objectively using twice-daily symptom scores for nasal (reflective total nasal symptom score [rTNSS] and instantaneous TNSS [iTNSS]) and ocular (reflective total ocular symptom score [rTOSS] and instantaneous TOSS [iTOSS]) symptoms, rhinoconjunctivitis quality-of-life questionnaires (RQOLQs), and acoustic rhinometry. All measurements were taken at baseline and at 4 and 8 weeks of treatment. Sixty-three patients who were randomized into the mometasone furoate group (n = 36) and the fluticasone furoate group (n = 27) completed the study. Seventy-six percent of patients had mild ocular symptoms, 20.5% had moderate symptoms, and only 2.6% had severe symptoms at baseline based on the iTOSS; 65.1% had mild nasal symptoms and 3% had severe nasal symptoms. There was significant reduction in the symptom scores after 1 week (p < 0.05). Both groups had significant improvement in RQOLQ scores after 1 month, which further improved at 2 months (p < 0.05). The nasal dimensions also improved in both groups (p < 0.05) but there was no statistically significant difference between groups. Both mometasone furoate and fluticasone furoate are effective as single-modality treatment of allergic rhinoconjunctivitis. The majority of patients manifest mild ocular symptoms that may be solely treated with intranasal steroids.

J Pak Med Assoc, 2011 May;61(5):500-1.
PMID: 22204190

The case of a 10-year-old girl is presented who had a slow-growing, painless swelling on the left side of the tongue since six months. This was associated with disturbances in mastication and phonation. Examination revealed a 5 cm x 4 cm. globular smooth, mobile mass on left side of the tongue. There was no neurological deficit and no neck nodes palpable. She underwent excision of the mass under general anaesthesia. Complete enucleation with primary closure was carried out. The patient had an uneventful postoperative recovery and histological evaluation was consistent with schwannoma. The patient was recurrence free after one year.

J Asthma Allergy, 2020;13:523-531.
PMID: 33149624 DOI: 10.2147/JAA.S275536

Purpose: The allergic phenotype of chronic rhinosinusitis (CRS) and central compartment atopic disease (CCAD) have been described. The CCAD is a radiological phenotype in patients with CRS that presents as a central mucosal disease due to allergy. The subset of patients having chronic rhinosinusitis with nasal polyps (CRSwNP) has not been well characterized. We aim to describe the clinical and radiological characterizations of patients presenting with the allergic phenotype of CRSwNP.
Patients and Methods: A cross-sectional study at a tertiary hospital was performed. Adult patients diagnosed with CRSwNP who had both allergology and radiological assessments were enrolled. The symptoms of allergic rhinitis, Lund-Kennedy (LK) endoscopic scoring, Lund-Mackay (LM) computed tomography scan of paranasal sinuses (CTPNS) scoring, CCAD features, skin prick test (SPT) and level of specific IgE were assessed. All the patients underwent SPT for house dust mites.
Results: A total of 38 patients were enrolled. Symptoms, endoscopic and CTPNS scores were higher in the allergy and CCAD groups compared to the nonallergy and nonCCAD groups. The symptom of "need to blow nose" was statistically significant in allergy vs nonallergy (p=0.01) and CCAD vs nonCCAD (p=0.02). There were significant differences in the endoscopic scores in both allergy and CCAD (allergy vs nonallergy, p=0.01; CCAD vs nonCCAD, p=0.03), and CT scores in both allergy and CCAD (allergy vs nonallergy, p=0.02; CCAD vs nonCCAD, p=0.02). All patients with CCAD have worse scoring than nonCCAD (LK score, p=0.03; LM score, p=0.02). Patients with allergy have more polypoidal involvement of the middle turbinates (left middle turbinate, p=0.141; right middle turbinate, p=0.074) and CCAD (left middle turbinate, p=0.017; right middle turbinate, p=0.009) than nonallergy and nonCCAD patients.
Conclusion: Allergic phenotype of CRSwNP has a worse clinical and radiological disease burden. Optimal treatment of allergy is essential for a better outcome.

Abdullah B, Lim EH, Mohamad H, Husain S, Aziz ME, Snidvongs K, et al.

Surg Radiol Anat, 2019 May;41(5):543-550.
PMID: 30542929 DOI: 10.1007/s00276-018-2157-3

PURPOSE: The variations of the anterior ethmoidal artery (AEA) in different populations should be recognized by surgeons to prevent unwarranted complications during surgery. The aim of this study was to assess the anatomical variations of AEA in Asian population.
METHODS: A cross-sectional study of 252 AEA identified by computed tomography (CT) of the paranasal sinuses. The multiplanar CT images were acquired from SOMATOM® Definition AS+ and reconstructed to axial, coronal and sagittal view at 1 mm slice thickness.
RESULTS: 42.5% of AEA was within skull base (grade I), 20.2% at skull base (grade II) and 37.3% coursed freely below skull base (grade III). The prevalence of supraorbital ethmoid cell (SOEC) and suprabullar cell (SBC) was 29.8% and 48.0%. The position of AEA at skull base has significant association with SOEC (p
The association between the reflux symptoms index and nasal symptoms among patients with non-allergic rhinitis

Hamizan AW, Choo YY, Loh PV, Abd Talib NF, Mohd Ramli MF, Zahedi FD, et al.

J Laryngol Otol, 2021 Feb;135(2):142-146.
PMID: 33494850 DOI: 10.1017/S0022215120002492

BACKGROUND: Laryngopharyngeal reflux symptoms assessed with the reflux symptom index can overlap with non-allergic rhinitis symptoms. This study aims to explore the association between the reflux symptom index and nasal symptoms in non-allergic rhinitis patients.
METHODS: A cross-sectional study was conducted on consecutive adults with non-allergic rhinitis. The reflux symptom index (score of more than 13 = laryngopharyngeal reflux) and nasal symptoms (categorised as mild (total score of 0-3), moderate (4-7) or severe (8-12)) were assessed.
RESULTS: The study included 227 participants (aged 58.64 ± 12.39 years, 59.5 per cent female). The reflux symptom index scores increased with total nasal symptom scores (mild vs moderate vs severe, 8.61 ± 6.27 vs 12.94 ± 7.4 vs 16.40 ± 8.10; p < 0.01). Logistic regression indicated that laryngopharyngeal reflux is more likely in patients with severe nose block (odds ratio 5.47 (95 per cent confidence interval = 2.16-13.87); p < 0.01).
CONCLUSION: Laryngopharyngeal reflux symptoms are associated with nasal symptom severity, and nasal symptoms should be primarily treated. Those with predominant nose block and laryngopharyngeal reflux symptoms are more likely to have laryngopharyngeal reflux.

Sai-Guan L, Husain S, Zahedi FD, Ahmad N, Gendeh BS

Iran J Otorhinolaryngol, 2020 Jul;32(111):213-222.
PMID: 32850509 DOI: 10.22038/ijorl.2019.34346.2138

Introduction: Sniffin' Sticks smell identification test is a tool used for evaluation of olfactory function but the results are culture-dependent. It relies on the subject's familiarity to the odorant and descriptors. This study aims to develop the Malaysian version of Sniffin' Sticks smell identification test suitable for local population usage.
Materials and Methods: The odorant descriptors and distractors of the original version of Sniffin' Sticks were translated into Malay language. It was then tested for familiarity and identifiability in 30 normosmic subjects. The descriptors were replaced until the familiarity of all descriptors and identification rates of odorants achieved ≥ 70%. The validity of the new cultural-adapted version was tested in 60 hypo-anosmic subjects and 60 normosmic subjects with Student t-test. The test-retest reliability was evaluated after two weeks with interclass correlation.
Results: Two odorant descriptors and nine distractors achieved familiarity <70% (13.3% - 66.7%) and were replaced. Another three culturally inappropriate distractors were also replaced. The mean score among the healthy subjects was significantly higher than the subject with smell dysfunction [13.7 (1.12) and 7.3 (3.42); t = 7.24 (df = 34.23), P<0.001]. The coefficient of correlation (r) between test and retest scores was 0.93 (P<0.001).
Conclusion: The cultural adapted Malaysian version of Sniffin' Sticks smell identification test is valid and has high test-retest reliability. This is the first smell identification test validated in Malaysia. It is effective for evaluation of olfactory function in local population.

Spontaneous unilateral orbital haematoma in children is not common and very rarely caused by scurvy. Scurvy is a clinical syndrome with a spectrum of clinical manifestations due to severe prolonged vitamin C deficiency leading to impairment of collagen synthesis over skin, bone, teeth and blood vessels. This paper presents a unique case of a 7- year-old girl with learning difficulty who presented with spontaneous right proptosis due to scurvy. Imaging studies suggestive of intra- orbital extraconal haemorrhage. The child was treated with a higher than recommended dose of vitamin C initially in emergency situation. She responded well and discharged without complication. Spontaneous orbital haematoma due to scurvy is very rare with less than 10 cases published in literature. The present case should raise the awareness regarding this forgotten disease and importance of balance nutrition amongst children.

Diagn Cytopathol, 2012 Nov;40(11):1010-4.
PMID: 21563319 DOI: 10.1002/dc.21706

Cutaneous metastasis of hepatocellular carcinoma (HCC) is very rare, accounting for less than 0.8% of all known cutaneous metastases and occurring in 2.7-3.4% of HCCs. With less than 50 such cases reported worldwide, most of which were diagnosed histologically on excised lesions, it can only be expected that diagnosis made on cytological features alone would be challenging. We report a case of cutaneous metastasis of HCC diagnosed based on cytological features and confirmed by Hep Par 1 immunopositivity of the cell block material. An 81-year-old man, who was known to have unresectable HCC, presented with a 1-month history of painless, left nasal alae mass. The mass measured 1.5 cm in diameter, and was multilobulated with a central necrosis. Fine needle aspiration of the mass was done. Smears were cellular, comprising of malignant cells in loose clusters and aggregates as well as singly dispersed. The malignant cells displayed moderate nuclear pleomorphism, occasional prominent nucleoli, and intranuclear pseudoinclusion. Cell block material demonstrated the trabeculae pattern of the malignant cells and Hep Par 1 immunopositivity. The final diagnosis of a metastatic cutaneous HCC was made. In conclusion, cutaneous HCC metastasis is rare and should be considered in the differential diagnosis in patients with a history of HCC presenting with suspicious skin lesion. In the right clinical setting, a confident diagnosis can be made in such cases by using the fine needle aspiration technique aided with immunopositivity for Hep Par 1 antibody of the aspirated material.
Fulltext Intractable Sneezing Unfolding a Hideous Truth

Ng JJ, Husain S, Ong HY, Zahedi FD, Wan Hamizan AK

Cureus, 2021 May 27;13(5):e15268.
PMID: 34194872 DOI: 10.7759/cureus.15268

Intractable sneezing is a diagnosis of exclusion and is mostly psychogenic. We reported a case of an 11-year-old girl who presented with uncontrollable bouts of sneezing for three weeks, which did not respond to conventional treatment. She was eventually diagnosed to have psychogenic intractable sneezing, which was triggered by an unfortunate family circumstance. She improved with psychotherapy and was discharged well. Literature review on intractable sneezing showed that patients were predominately female teenagers and mostly recovered after psychotherapy. Multidisciplinary team effort especially with a child psychiatrist is important for the treatment and follow-up of these patients. Imaging should also be routinely performed as some had underlying organic causes that presented as intractable sneezing.
Fulltext Management of rhinosinusitis in adults in primary care

Husain S, Amilia HH, Rosli MN, Zahedi FD, Sachlin IS, Development Group Clinical Practice Guidelines Management of Rhinosinusitis in Adolescents & Adults

Malays Fam Physician, 2018;13(1):28-33.
PMID: 29796207 MyJurnal

Rhinosinusitis is a common health problem encountered in primary care. It is due to mucosal inflammation of the nose and paranasal sinuses. Less than 2% of the cases are associated with bacterial infections. Diagnosis is based on clinical symptoms and supported by nasal endoscopy and imaging studies. Intranasal corticosteroids and normal saline irrigation are important treatments. Antibiotics are seldom indicated.
Local specific Immunoglobulin E among patients with nonallergic rhinitis: a systematic review

Hamizan AW, Rimmer J, Husain S, Alvarado R, Tatersall J, Sewell W, et al.

Rhinology, 2019 Feb 01;57(1):10-20.
PMID: 30219822 DOI: 10.4193/Rhin18.074

BACKGROUND: Allergen specific immunoglobulin can be present in the nasal mucosa of patients with non-allergic rhinitis (NAR). This condition is defined as local allergic rhinitis. However, the reported presence of nasal specific immunoglobulin E (nspIgE) among NAR is variable. The aim of this review was to summarize the studies which reported the presence of nspIgE among patients diagnosed as NAR.
METHODS: Embase (1947- ) and Medline (1946-) were searched until 6th June 2017. A search strategy was utilized to identify studies on nspIgE among patients with NAR. The target population was patients with symptoms of rhinitis, but negative systemic allergen sensitization. Studies with original data on detectable nspIgE among the NAR population were included. Meta-analysis of single proportions as a weighted probability %(95%CI) was performed. Heterogeneity was explored amongst studies.
RESULTS: A search strategy returned 2286 studies and 21 were included. These studies involved 648 participants with NAR. NspIgE was detected using either; 1. nasal secretions, 2. epithelial mucosa sampling, 3. tissue biopsies or 4. In-situ tests. Metaanalysis was performed on studies with nasal secretions. The weighted proportion of detectable nspIgE in nasal secretions within patients with NAR was 10.2 (7.4-13.4) %. Population definitions partly explained variability. Detection of nspIgE was lower in patients without a history suggestive of allergy compared to those with a positive allergic history (0 (0-3.1) % v 19.8 (14.5-25.6) %, p<0.01).
CONCLUSION: NAR with positive allergy history suggests presence of nspIgE. These patients warrant further allergology evaluation to confirm localized nasal allergy, as they benefit from allergy therapy such as immunotherapy.
