Co-occurrence of otitis media with effusion and another environment-dependent disease (selected allergic conditions)

Introduction

Otitis media eith effusion (OME) is an inflammatory condition of the middle ear that involves accumulation of sterile fluid or effusion in the tympanic cavity with the tympanic membrane intact. The pathophysiology of OME is undoubtedly multifactorial.

Aim

To assess the co-occurrence of OME, allergic rhinitis, and asthma.

Material and methods

The study involved a group of 18,617 subjects aged 6-7 years, 13-14 years, or 20-44 years. ECRHS and ISAAC questionnaires, validated and adopted for Polish conditions, were used in the study.

Results

OME increases the risk of developing allergic rhinitis by nearly two-fold (OR = 2.07, 95% CI: 1.738-2.479 in 6-7-year-olds; OR = 1.61, 95% CI: 1.299-1.995 in 13-14-year-olds, and OR = 1.55, 95% CI: 1.262-1.83 in 20-44-year-olds). Protective factors against otitis media with effusion include the number of siblings (the more children in the family, the higher the risk of chronic OM; OR = 2.00, 95% CI: 1.15-1.346) and consumption of dairy products rich in lactic acid bacteria.

Conclusions

OME significantly more often co-exists with other conditions, particularly allergic rhinitis.

Intranasal combo: fixed-dose combination of mometasone furoate and olopatadine hydrochloride in therapeutic strategies for rhinosinusitis

A novel strategy for the treatment of allergic rhinitis results from the innovative combination of antihistamine and intranasal corticosteroid drugs. By combining two preparations with different mechanism of action, this novel approach facilitates quick and effective controls of all upper respiratory tract allergy symptoms. The article presents the results of a study of olopatadine hydrochloride and mometasone furoate fixed-dose combination (GSP301) administered intranasally from a spray formulation, with an attempt at positioning the treatment within the ARIA and EPOS guidelines.

Differential diagnostics of food allergy as based on provocation tests and laboratory diagnostic assays

Due to the scale of the phenomenon, food allergy constitute a significant health problem and significantly impair the quality of life of patients. Differential diagnostics, including skin tests, sIgE detection tests, basophil and mast cell activation tests as well as double-blind placebo-controlled food challenge tests, is the gold standard in the diagnosis of food allergy. Recently, increasing attention has been paid to the potential use of nasal provocation test in the diagnosis of food allergy. Allergen dose, protocol standardization, assessment of subjective complaints and objectivization of test results are important factors determining the applicability of provocation tests.

Why the role of mHealth in allergy diagnosis and treatment adherence cannot be overlooked

BACKGROUND

Allergic diseases-rhinitis and asthma-are the most common chronic conditions affecting adults. Traditional approaches to allergy diagnosis and treatment do not meet the health needs of all patients. Treatment adherence remains a challenge for physicians. The ubiquity of Internet access paired with limited in-person contact with medical personnel in the course of the COVID-19 pandemic demonstrated the potential of mHealth in communicating health information. BODY: The abundance of new applications dedicated to various medical specialties encourages reflection on the informed use of such tools. The paper takes a closer look at the potential of mHealth and presents conclusions of selected studies focusing on the use of good apps. The strength weakness opportunities threats analysis was used to illustrate the strengths of the mHealth strategy, as well as its advantages, limitations and areas in need of further development.

CONCLUSION

The strength of mHealth depends on the quality and quantity of the collected patient data, its reliable processing, as well as publication of outcomes and conclusions from analyses. Therefore, it is necessary to promote the use of validated applications among patients, physicians and medical staff.

Methodological Principles of Nasal Food Challenge

Thanks to their valuable assessment possibilities (subjective complaints and changes in nasal patency during the examination), nasal provocation tests may serve as an alternative tool for oral food challenges in the future. However, this test requires successive attempts to regulate its methodology in order to develop a standardized lyophilisate form and determine the threshold dose for a positive result. The study objective was to present the methodological foundation for nasal food allergen provocation tests induced by freeze-dried powdered chicken egg whites. A control group of 25 individuals with no history of allergy to chicken eggs or any other allergy was included in the study. Optical rhinometry and visual analog scales were used to assess the response of nasal mucosa to local allergen challenges. Minor variations in nasal flows, as measured by optical rhinometry, were observed in the provocation tests. The mean optical density measurements (as measured regardless of the allergen dose used) varied from positive to negative values and vice versa, e.g., amounting to 0.018 OD (standard deviation 0.095) at 15 min and -0.011 OD (standard deviation 0.090) at 30 min. No significant differences were observed concerning the perceived nasal discomfort using the visual analog scale. Due to the absence of nasal mucosal reactivity, nasal challenge is an excellent methodological tool for implementing food allergen tests.

Oral and nasal provocation test in chicken egg allergy-case report

INTRODUCTION

Allergy to chicken egg protein is a common form of food allergy. The most common clinical presentation includes gastrointestinal, skin, and respiratory symptoms. Differential diagnosis, including provocative tests, is critical in diagnosis.

CASE DESCRIPTION

We present a case of a 21-year-old patient with egg allergy, who underwent a double-blind food provocation test with placebo (evaluating subjective complaints from the gastrointestinal tract) and a titrated nasal provocation test using dry chicken egg content. We assessed the response of the nasal mucosa in the provocation test using the visual analogue scale (VAS), acoustic and optical rhinometry, as well as measurements of nitric oxide concentration in the exhaled air. During the provocation test, we measured the changes in the transverse section of the nasal passages, which were accompanied by subjective complaints measured with the VAS scale, using objective techniques. In the nasal provocation test with a dose of 20 µg of chicken egg protein, we observed an increase in the reactivity of the nasal mucosa and a decrease in the level of nitric oxide in the exhaled air from the upper airways (920 ppb before the provocation test and up to 867 ppb during the early stage of the allergic reaction). During the provocation tests, we recorded typical symptoms associated with the early stage of the allergic reaction; including nasal obstruction (1.2 cm), leakage of watery discharge (0.8 cm) in the food test, and itchy nose (1.1 cm) in the food test vs. the nasal test: 4.6, 2.8, and 3.5 cm, respectively.

CONCLUSIONS

The nasal mucosa provides convenient conditions for evaluation of the severity of allergy to common food allergens, including chicken egg allergens.

Evaluation of selected aspects of the hygiene hypothesis and their effect on the incidence of allergy

OBJECTIVES

The development of allergic conditions is largely dependent on the interactions between genetic (individual genetic predisposition) and environmental factors (exposure to risk factors). The aim of this study was an attempt to assess the influence of selected elements of the hygiene theory in the development of allergic diseases such as allergic rhinitis and asthma.

MATERIAL AND METHODS

The study group consisted of 5518 women and 3868 men. The method that was used was the European Community Respiratory Health Survey II and International Study of Asthma and Allergies in Childhood questionnaire validated and adapted to Central and Eastern European conditions. The project was conducted in 8 urban areas (Gdańsk, Wrocław, Poznań, Katowice, Kraków, Lublin, Białystok, Warsaw) and 1 rural area (Krasnystaw county). This study had 2 stages; the first stage involved grouping the 22 500 respondents based on their questionnaire responses with the use of a Personal Digital Assistant (PDA); the second stage involved 7000 subjects, who underwent additional assessments: skin prick tests (birch, grasses/cereals, Dermatophagoides pteronyssinus and Dermatophagoides farinae, molds [set I: Botrytis cinerea, Cladosporium herbarum, Alternaria tenuis, Curvularia lunata, Fusarium moniliforme, Helminthosporium], molds [set II: Aspergillus fumigatus, Mucor mucedo, Penicillium notatum, Pullularia pullulans, Rhizopus nigricans, Serpula lacrymans], cat, dog, molds Cladosporium herbarum, Alternaria tenuis) and spirometry tests.

RESULTS

The age at which children attend the nursery school is critical to the development of allergic diseases; in allergic rhinitis, the risk of an IgE-dependent reaction is 2 times higher in the second than in the first year of life (p = 0.00147, p < 0.05), while in asthma, having a large number of siblings increases the risk of developing obstructive disease by almost 6 times (p = 0.00316, p < 0.05).The age at which children attend the nursery school is critical to the development of allergic diseases; in allergic rhinitis, the risk of an IgE-dependent reaction is 2 times higher in the second than in the first year of life (p = 0.00147, p < 0.05), while in asthma, having a large number of siblings increases the risk of developing obstructive disease by almost 6 times (p = 0.00316, p < 0.05).

CONCLUSIONS

The hygiene theory is particularly applicable and can explain the relationship of selected habits in the development of allergic diseases. Int J Occup Med Environ Health. 2023;36(1):69-83.

Nasal mucosal reactivity assessment via a double-blind placebo-controlled food challenge with cow's milk allergens

Background

Allergies, including food allergies, are a considerable clinical and public-health problem. The introduced preventive measures and differential diagnostics, including oral food challenges, are the gold standard for determining further treatment planning.

Case presentation

We present a case of an 18-year-old girl with a cow’s milk allergy who underwent an oral food challenge (double blind oral food challenge). Such a challenge may be confounded by inducing a response from other systems and organs, which provides theoretical grounds for the use of other methods of assessing the body’s response to food allergens (response demonstrated by the upper respiratory tract). Based on this idea, in order to assess the degree of mucosal response, we used optical rhinometry as an objective method for nasal patency evaluation, as well as identification of tryptase level in nasal lavage fluid and exfoliative cytology of nasal mucosa. The results of these tests confirmed positive reaction of the nasal mucosa in the course of the oral allergen challenge.

Conclusions

The observed increase in the nasal mucosal reactivity that accompanies oral food challenges may suggest a potential for using food allergens in nasal allergen provocation testing in order to diagnose food allergies.

Prevention of perennial allergic rhinitis in the conception of coordinated healthcare in Poland

INTRODUCTION

The primary prevention is intended to prevent the development of diseases, secondary prevention aims to limit disease progression, and tertiary prevention involves reducing disease-associated symptoms. The purpose of this study was to assess the use of selected forms of secondary prevention by patients diagnosed with perennial allergic rhinitis. Moreover, this paper presents the ways in which the adopted organizational solutions could be utilized as part of coordinated healthcare to benefit patients with perennial allergies.

MATERIAL AND METHODS

The study population comprised 18,617 respondents, 4783 of whom (including patients allergic to Dermatophagoides pteronyssinus and Dermatophagoides farinae) were qualified to undergo a medical examination. The study used ECRHS and ISAAC questionnaires adapted for Europe.

RESULTS

Nearly 20% of patients diagnosed with chronic allergic rhinitis used preventive measures against house dust mites; this is in contrast with 13% in the control group (p = 1.358e-07). The secondary preventive measures most commonly used in the study group were, in descending order of frequency, mattress protectors and anti-dust-mite spray. Undertaking preventive measures was most common among study participants with higher education and residents of large cities.

CONCLUSIONS

The proportion of patients diagnosed with a dust-mite allergy, who undertook preventive measures against perennial allergic rhinitis, was relatively low. Building, maintaining, and continual strengthening the doctors' relationship with chronic allergy patients may shift the nature of healthcare services more towards preventive measures, for the implementation of which the patient will be co-responsible under the coordinated healthcare system.

The effect of infectious agents on the prevalence of allergies

PURPOSE

The role of infectious agents in allergy development is ambivalent. On one hand, there are reports of an association between a previous infection (especially a viral respiratory tract infection) and developing hypersensitivity to inhaled allergens, which in turn may increase the risk of developing allergic reactions. On the other hand, there are reports emphasizing a protective effect of a number of infectious agents against allergy development. The aim the study was to find possible associations between a past infectious or parasitic disease and an allergic condition.

MATERIAL AND METHODS

The study population was a group of 18,648 subjects. The study, which was a part of the project: 'Implementation of a System for the Prevention and Early Detection of Allergic Diseases in Poland', was conducted in 9 selected regions of Poland and used the ECRHS and ISAAC questionnaires adapted for Europe. The following statistical tools were used: Pearson's chi-squared test, Fisher's exact test, and logistic regression.

RESULTS

This research was an attempt to clear association between a history of measles or viral hepatitis and the likelihood of developing asthma, especially in males (χ² = 5.29; p<0.05). Past parasitic disease showed a clear association with a suspected allergic rhinitis in various groups of patients (differing both in terms of sex and age).

CONCLUSIONS

A history of some forms of either infectious or parasitic diseases has a measurable effect on the risk of developing allergies.

A case of lymphocytic esophagitis in a woman with multiple allergies

Background

Lymphocytic esophagitis is a newly recognized entity of unknown origin. Dysphagia is defined as difficulty swallowing and represents a common symptom in the general population with a prevalence of approximately 20%. Chronic inflammation of the esophageal wall may manifest itself clinically and endoscopically, mimicking inflammation of another origin. However, little is known about the pathogenesis of the disease, as patients are seldom suspected and rarely diagnosed with lymphocytic esophagitis.

Case presentation

Here, we present a rare case of lymphocytic esophagitis in a patient with multiple allergies and suspected eosinophilic esophagitis. A 28-year-old woman with polyvalent sensitization to food and inhalant allergens presented with intermittent dysphagia, a sensation of a foreign body in the throat, itchiness of the oral cavity after ingesting certain foods, heartburn, and prolonged chewing time. A skin prick test showed positive results for birch-tree, alder, hazel, and rye pollen, as well as house dust mites. Apart from obesity (BMI 30 kg/m²), multiple pustules and excoriations on the skin, her physical examination was insignificant. Esophagogastroduodenoscopy (EGD) was performed revealing full-length but discrete trachealization of the esophagus. A barium swallow test showed slowing of esophageal peristalsis in the recumbent position. No esophageal pathology was observed. A histopathological analysis of mucosal samples revealed slight hyperplasia of the basal layer of the esophagus, and the stomach showed changes typical of chronic gastritis.

Conclusions

In summary, this clinical case illustrates that lymphocytic esophagitis, as a newly recognized entity, should be considered in the differential diagnosis of chronic dysphagia. Additionally, when treating allergic patients, clinicians should be aware that lymphocytic esophagitis, distinct from eosinophilic esophagitis, should be considered in the diagnosis of patients with atopy and upper gastrointestinal symptoms.

The role of the nasal allergen provocation test in local allergic rhinitis cases: a preliminary report

INTRODUCTION

The current state of knowledge is that allergic rhinitis can occur in two forms. One is allergic rhinitis as a manifestation of a systemic allergy with systemic atopy and positive results of skin prick tests or sIgE tests. The other is local allergic rhinitis (LAR) as a local allergic reaction affecting only the nasal mucosa without systemic atopy.

AIM

To attempt to assess the usefulness of the nasal allergen provocation test for the purposes of differential diagnosis and the qualification of LAR patients for therapy.

MATERIAL AND METHODS

The subjects in the study were a group of 6 adults diagnosed with LAR on the basis of their medical history and the results of nasal allergen provocation tests, with the allergens being house dust mites (Dermatophagoides pteronyssinus, Dermatophagoides farinae). The methods adopted in the study were a point-based rating scale as a measure of nasal/extranasal complaints and active anterior rhinomanometry.

RESULTS

Significant differences (p < 0.05) were observed, using the subjective rating scale, in relation to registered nasal and extranasal complaints in the early phase of the allergic reaction. Similarly, the rhinomanometry method revealed significant differences in nasal resistance values before and after the administration of an allergen.

CONCLUSIONS

The nasal allergen provocation test is the only testing tool that objectively measures the degree of the patient's allergic reactions and is useful in qualifying LAR patients for further therapy.

A case of allergy to Silybum marianum (milk thistle) and Eragrostis tef (teff)

Background

This paper presents a peculiar first case of an allergy to Silybum marianum (milk thistle) and Eragrostis tef (teff). Both teff and milk thistle have been presented in the literature (both domestic and foreign) in a positive light, the former as a new part of gluten-free diet, and the latter as a treatment for a number of conditions, particularly those of the liver.

Case presentation

A 29-year-old male presented at our clinic due to an episode of itching and burning in his mouth, swollen tongue, and difficulty swallowing following ingestion of teff flakes. He also reported sneezing, runny nose, watering and burning eyes, and wheezing following inhalation exposure to ground milk thistle. The patient’s occupation is associated with exposure to these allergens. The patient underwent comprehensive allergy diagnostic assessments (including skin-prick testing, serum specific IgE levels, Faber test, spirometry, and acoustic rhinometry) and gastroenterological assessments. The diagnosis was established on skin tests with native allergens (milk thistle 16/35, teff flour 22/60, negative control 0/0, histamine 3/5) provided by the patient. There are no commercially available (standardized) tests for milk thistle or teff either in Poland or anywhere else in the world.

Conclusions

Milk thistle is available in the form of dry, finely-ground preparations (which are used as additives to bread, soups, and yoghurts) and extracts (which are used as ingredients in over-the-counter herbal remedies). Teff is a gluten-free cereal whose grains are rich in methionine, calcium, iron, folic acid, and antioxidants. This case report presents milk thistle and teff as potentially new allergens. A literature review revealed no similar allergy cases in Poland or elsewhere in the world.

Local allergic rhinitis: nasal allergen provocation testing as a good tool in the differential diagnosis

Local allergic rhinitis (LAR) is a specific phenotype of allergic rhinitis. One characteristic feature of LAR is a medical history indicative of an allergic disease, negative skin-prick test results, undetectable levels of specific IgE, and a positive allergen-specific nasal provocation test. This paper presents a case of a patient with LAR and underlying house dust mite allergy, who was ultimately diagnosed >10 years after the onset of his first symptoms. Currently, there are only pharmacological treatments available for LAR. However, some studies show encouraging results with the use of allergen-specific immunotherapy in LAR, which offer hope for a future use of this causative treatment in LAR patients.

Dissociating polysensitization and multimorbidity in children and adults from a Polish general population cohort

Background

Links between multimorbidity of allergic diseases and allergen sensitization are still under debate, especially in adults. This study aimed to establish a relationship between polysensitization and allergic multimorbidity in children and adults and the allergens involved in multimorbidity.

Material and method

A cross-sectional multicentre study enrolled children aged 6-7 and 13-14 years and adults aged 20-44 years from a Polish national cohort. The diagnosis of allergic diseases was made by a physician. Skin prick tests to 13 allergens and serum IgE levels to 4 allergens were tested.

Results

Among the 3856 participants, single disease (asthma, allergic rhinitis or atopic dermatitis) was diagnosed in 27.7% subjects and allergic multimorbidity in 9.3%. Allergic multimorbidity occurred more commonly in children than in adults (p < 0.01). Asthma or atopic dermatitis alone were not associated with polysensitization. Rhinitis and multimorbidity were associated with polysensitization. Allergic multimorbidity occurred in 2.2% of participants with negative skin prick tests, 9.8% of those with one positive prick test (SPT ≥ 3 mm) and 20.6% of polysensitized ones (p < 0.001). There was an increasing risk of multimorbidity depending on the number of positive prick tests for both SPT ≥ 3 mm (OR 9.6-16.5) and SPT ≥ 6 mm (OR 5.9-13.7). A statistically significant relationship was found between allergic multimorbidity and sensitization to cat and mite allergens.

Conclusions

Multimorbidity is associated with polysensitization especially in children compared with adults in Polish population cohort. New insights into single disease patterns were found: bronchial asthma is the strongest risk factor for the development of multimorbidity in comparison with allergic rhinitis and atopic dermatitis.

The Safety of Nasal Allergen Challenge Test Assessed in Lower Airways

The aim of the study was to assess the safety of nasal allergen challenge, and the use of certain parameters applied in assessing the condition of the respiratory system. We enrolled 30 patients diagnosed with allergy to common environmental allergens and 30 healthy controls. The safety of nasal challenge tests with an allergen was assessed by measuring the concentration of exhaled nitric oxide from the lower respiratory tract (eNO) and forced expiratory volume in one second (FEV1) in a spirometry test. In the early phase of the allergic reaction, extra-nasal symptoms were observed, namely cough and breathlessness. These measured symptoms using the VAS scale, were far more frequent in the patients diagnosed with perennial allergic rhinitis. The eNO and FEV1 values in the spirometry test did not show any statistically significant changes. No correlation was observed between the breathlessness and cough complaints to the eNO concentration levels (cough: r=0.019, p=0.921; breathlessness: r=-0.088, p=0.644) nor the FEV1 level (cough: r=0.002, p=0.983; breathlessness: r=-0.072, p=0.751) in the spirometry test. In the early phase of the allergic reaction, nasal allergen challenge do not cause any significant changes in the lower airways, as measured with the use of certain parameters applied in assessing the function of the lower airways' function.

[Management of recurrent sinonasal inverted papilloma in the experience of ENT Department Medical University of Warsaw]

INTRODUCTION

Inverted papilloma is benign epidermal neoplasm of not recognized etiology. The lesion is estimated to represent 0.5-4% of sinonasal tumors. Generally inverted papilloma is unilateral, arises from the lateral nasal wall and characterizes with local destruction and rapid growth. The tumor can possibly undergo malignant transformation. The treatment of choice is surgery, recently endoscopic approach is considered to be superior to the open approach.

THE AIM OF STUDY

was evaluation of recurrent inverted papilloma treatment results in the experience of Otolaryngology Department, Medical University of Warsaw, from 1982 to 2009.

MATERIAL

The group of 124 patient (66 men and 58 women) aged from 26 to 79 with inverted papilloma operated between 1982 and 2009 were enrolled in the study. Follow up was from 6 months to 27 years.

RESULTS

Most common primary localization of the tumor was combined lateral nasal wall and maxillary sinus (42%). In 37% the lesion involved unilaterally the lateral nasal wall, maxillary sinus and ethmoid sinuses, rarely it was localized only in the lateral nasal wall (16.1%) and exclusively in the nasal septum (4.8%). All the patients were treated surgically, 46% of patients underwent endoscopic procedure, 37.1% lateral rhinotomy, 15% Denker rhinotomy and 1.6% midfacial degloving. Recurrence was observed in 15.3% including 57.9% after endoscopic surgery, 26% after Denker operation and 15.8% after lateral rhinotomy. Malignant transformation was observed in 5 patient (4%). All the patients with recurrent inverted papilloma were treated surgically, 5.3% of patient underwent midfacial degloving, 5.3% Caldwell-Luc operation, 10.5% endoscopic procedure, 26.3% Denker operation and 52.6% lateral rhinotomy.

CONCLUSIONS

1. Endonasal and open approach should be considered in the surgical treatment of recurrent inverted papilloma. 2. Endoscopic approach is preferred in the recent years but qualification for each method should depend on lesion localization, extent and volume. 3. Regular follow-up enables early recurrence diagnosis and treatment.

[Abscess of the parotid gland]

Inflammatory processes developing in the region of parotid gland can be specific or non-specific. Non-specific inflammation of bacterial or viral origin, which almost always are secondary to inflammatory processes in the region of oral cavity and pharynx, can be caused by presence of sialoliths in parotid gland or in the excretory duct. In the paper we presented 11 patients treated for the reason of parotid gland abscesses. Etiology, the course of the disease, and the method of treatment were analyzed.
