ALLERGY, ASTHMA, AND CLINICAL IMMUNOLOGY : OFFICIAL JOURNAL OF THE CANADIAN SOCIETY OF ALLERGY AND CLINICAL IMMUNOLOGY 2024; 20:45. [PMID: 39118164 PMCID: PMC11311964 DOI: 10.1186/s13223-024-00899-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Accepted: 05/21/2024] [Indexed: 08/10/2024]
Abstract
Allergic rhinitis (AR) is a prevalent disease in Canada that affects both children and adults. Several guidelines for the management of AR have been published by professional allergy societies worldwide. However, there are regional differences in the clinical management of AR, and regulatory approval of some AR pharmacotherapies varies among countries. Thus, six research questions specific to the treatment of AR in Canada were identified for this focused practice parameter. Reviews of the literature published since 2016 were conducted to obtain evidence-based support for the responses of the Work Group to each research question. In response to research question 1 "In patients with symptoms indicative of AR, is serum-specific IgE sufficient to identify candidates for immunotherapy or is a skin prick test mandatory?" the Work Group concluded that either sIgE testing or skin prick test are acceptable for diagnosing AR and guiding immunotherapy. In response to research question 2 "When taking into account the preferences of the patient and the prescriber (stakeholder engagement) should second-generation oral antihistamine (OAH) or intranasal corticosteroid (INCS) be first line?" the Work Group concluded that existing guidelines generally agree on the use of INCS as a first-line therapy used for AR, however, patient and provider preferences and considerations can easily shift the first choice to a second-generation OAH. In response to research question 3 "Is a combination intranasal antihistamine (INAH)/INCS formulation superior to INCS plus OAH? Do they become equivalent after prolonged use?" the Work Group concluded that that the combination INAH/INCS is superior to an INCS plus OAH. However, there was insufficient evidence to answer the second question. In response to research question 4 "Do leukotriene receptor antagonists (LTRA) have a greater benefit than OAH in AR for some symptoms to justify a therapeutic trial in those who cannot tolerate INCS?" the Work Group concluded that LTRAs have inferior, or at best equivalent, daytime or overall symptom control compared with OAH, but LTRAs may improve nighttime symptom control and provide benefits in patients with AR and concomitant asthma. In response to research question 5 "Should sublingual immunotherapy (SLIT) tablets be considered first-line immunotherapeutic options over subcutaneous immunotherapy (SCIT) based on the evidence of efficacy?" the Work Group concluded that the choice of SLIT or SCIT cannot be made on efficacy alone, and differences in other factors outweigh any differences in efficacy. In response to research question 6 "Based on efficacy data, should ALL patients seen by an allergist be offered SLIT or SCIT as a treatment option?" the Work Group concluded that the efficacy data suggests that SLIT or SCIT should be used broadly in patients with AR, but other clinical concerns also need to be taken into consideration.

Comparative efficacy and acceptability of licensed dose intranasal corticosteroids for moderate-to-severe allergic rhinitis: a systematic review and network meta-analysis. Front Pharmacol 2023; 14:1184552. [PMID: 37288109 PMCID: PMC10242043 DOI: 10.3389/fphar.2023.1184552] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Accepted: 05/09/2023] [Indexed: 06/09/2023] Open
Abstract
No evidence shows that one intranasal corticosteroid (INCS) is better than another for treating moderate-to-severe allergic rhinitis (AR). This network meta-analysis assessed the comparative efficacy and acceptability of licensed dose aqueous INCSs. PubMed/MEDLINE, Scopus, EMBASE, and the Cochrane Central Register of Controlled Trials were searched until 31 March 2022. Eligible studies included randomized controlled trials comparing INCSs with placebo or other types of INCSs in patients with moderate-to-severe allergic rhinitis. Two reviewers independently screened and extracted data following the Preferred Reporting Items in Systematic Reviews and Meta-analysis guideline. A random-effects model was used for data pooling. Continuous outcomes were expressed as standardized mean difference (SMD). The primary outcomes were the efficacy in improving total nasal symptom score (TNSS) and treatment acceptability (the study dropout). We included 26 studies, 13 with 5,134 seasonal AR patients and 13 with 4,393 perennial AR patients. Most placebo-controlled studies had a moderate quality of evidence. In seasonal AR, mometasone furoate (MF) was ranked the highest efficacy, followed by fluticasone furoate (FF), ciclesonide (CIC), fluticasone propionate and triamcinolone acetonide (TAA) (SMD -0.47, 95% CI: -0.63 to -0.31; -0.46, 95% CI: -0.59 to -0.33; -0.44, 95% CI: -0.75 to -0.13; -0.42, 95% CI: -0.67 to -0.17 and -0.41, 95% CI: -0.81 to -0.00), In perennial AR, budesonide was ranked the highest efficacy, followed by FF, TAA, CIC, and MF (SMD -0.43, 95% CI: -0.75 to -0.11; -0.36, 95% CI: -0.53 to -0.19; -0.32, 95% CI: -0.54 to -0.10; -0.29, 95% CI: -0.48 to -0.11; and -0.28, 95% CI: -0.55 to -0.01). The acceptability of all included INCSs was not inferior to the placebo. According to our indirect comparison, some INCSs have superior efficacy to others with moderate quality of evidence in most placebo-controlled studies for treating moderate-to-severe AR.

Abstract
PURPOSE Endoscopic sinus surgery (ESS) is the standard treatment strategy for chronic rhinosinusitis (CRS) resistant to medical treatment, and it is known to have postoperative complications and recurrences, which in turn result in suboptimal outcomes. Several methods are used to prevent postoperative scarring, adhesions, oedema, infection or recurrences in cavities. The role of steroids in improving postoperative outcomes is well established. They can be administered systemically or locally to enhance drug delivery into paranasal sinuses. In this study, we used triamcinolone irrigation immediately following surgery on one side of the nose, in patients with bilateral disease. The objective of this study was to evaluate the effect of intra-operative triamcinolone irrigation on postoperative outcomes, in patients with bilateral pansinusitis. METHODS It was an interventional randomized controlled study, conducted at a tertiary care centre in North India. The analysis of 58 patients with bilateral pansinusitis was done from September 2020 to August 2021. At the conclusion of ESS, each patient was randomized to receive triamcinolone irrigation (4 ml of 40mg/ml solution) once and followed by merocel (polyvinyl acetal) packing on one side, while the contralateral side was packed with merocel soaked with saline. Nasal cavities were evaluated using a Hopkins rod endoscope in the postoperative 1st, 3rd, 8th and 12th weeks to look for the presence of postoperative crusting, oedema, polypoidal changes, and discharge. Perioperative sinus endoscopic scores (POSE) were used for endoscopic staging. RESULTS The most commonly affected age group was 31-45 years accounting for 39.7%. Males were affected more (63.7%) than the female population (36.3%). There was a reduction in the average POSE scores at the treatment site at all follow-up stages with a significant reduction in crusting, oedema, and scarring in the treatment site (P-value <0.001). CONCLUSION Triamcinolone irrigation effectively improves postoperative outcomes and reduces early postoperative complications in CRS patients.

Abstract
Allergic rhinitis (AR) is one of the most common diseases in the world, which is based on IgE-mediated inflammation that develops after exposure to various allergens. About 40% of people suffer from the same or other allergic diseases, every third inhabitant of the Earth has symptoms of AR and every tenth has bronchial asthma. According to the ARIA classification, ARs are divided: by the nature of the flow, by the severity of the flow and by the stage of the flow; for symptoms, the proposed therapy, consisting of sequential steps. Groups of drugs include: systemic or topical blockers of histamine H1 receptors, intranasal and systemic corticosteroids, mast cell stabilizers (intranasal cromones), M-antagonists, antagonists of leukotriene receptors. Medicines do not give a lasting effect after their cancellation, therefore, with persistent AR, treatment should be prolonged; methods of application more often oral or intranasal. The advantages of the pharmacological antiallergic effect of InHCS are the simultaneous inhibition of both the early and late phases of the allergic response and the inhibition of all AR symptoms. The advantage of InHCS over oral administration is the minimal risk of developing systemic side effects against the background of the creation of adequate concentrations of the substance in the nasal mucosa, which allows to control the symptoms of AR. Based on data from a number of studies, the advantages of intrasal corticosteroids for AR, in particular fluticasone propionate, are used.

Efficacy of triamcinolone acetonide-impregnated Gelfoam nasal pack in management of chronic sinusitis with nasal polyps following endoscopic sinus surgery: a perfectly matched, placebo-controlled trial study. Eur Arch Otorhinolaryngol 2021; 279:2915-2924. [PMID: 34559269 DOI: 10.1007/s00405-021-07071-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2021] [Accepted: 09/05/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE This perfectly matched, double-blinded, placebo-controlled trial study was performed to investigate the efficacy of triamcinolone acetonide (TAA)-impregnated Gelfoam nasal pack in management of different endotypes of chronic rhinosinusitis with nasal polyps (CRSwNP) following endoscopic sinus surgery (ESS). METHODS One hundred and four patients with bilateral CRSwNP undergoing ESS were selected and randomized to receive TAA-soaked nasal packing in one nostril and saline-impregnated dressing contra-laterally. Validated Perioperative Sinus Endoscopy (POSE) scoring system was used to assess the participants' condition at postoperative months 1, 3, 6, 12, and 18. RESULTS The treatment side of eosinophilic CRSwNP (EosCRSwNP) group had significantly better endoscopic scores than the contralateral control side in all follow-up visits (P < 0.05 for all comparisons) except for the first postoperative month. No significant difference was detected between the TAA- and saline-treated nostrils in the non-eosinophilic CRSwNP (nonEosCRSwNP) subgroup during the follow-up period. Intergroup comparisons revealed a borderline better POSE score for the treatment side of the EosCRSwNP group compared with the treatment nostril of the nonEosCRSwNP group at months 12 (P = 0.041) and 18 (P = 0.044). At the end of the study period, the treatment side of the EosCRSwNP group demonstrated better clinical response than the saline-treated side in terms of the total POSE scores (P = 0.019), middle turbinate synechia (P = 0.008), middle meatal narrowing (P = 0.010), ethmoid polypoid changes (P = 0.039), ethmoid polyposis (P = 0.027), ethmoid cavity secretions (P = 0.042), and sphenoid severity (P = 0.018). CONCLUSION TAA-soaked Gelfoam dressing following bilateral ESS was found to be an effective method for treating CRSwNP particularly for the eosinophilic endotype of the disease.

Abstract
3-Ketosteroid Δ1-dehydrogenase catalyzes the 1(2)-dehydrogenation of 3-ketosteroid substrates using flavin adenine dinucleotide as a cofactor. The enzyme plays a crucial role in microbial steroid degradation, both under aerobic and anaerobic conditions, by initiating the opening of the steroid nucleus. Indeed, many microorganisms are known to possess one or more 3-ketosteroid Δ1-dehydrogenases. In the pharmaceutical industry, 3-ketosteroid Δ1-dehydrogenase activity is exploited to produce Δ1-3-ketosteroids, a class of steroids that display various biological activities. Many of them are used as active pharmaceutical ingredients in drug products, or as key precursors to produce pharmaceutically important steroids. Since 3-ketosteroid Δ1-dehydrogenase activity requires electron acceptors, among other considerations, Δ1-3-ketosteroid production has been industrially implemented using whole-cell fermentation with growing or metabolically active resting cells, in which the electron acceptors are available, rather than using the isolated enzyme. In this review we discuss biotechnological applications of microbial 3-ketosteroid Δ1-dehydrogenases, covering commonly used steroid-1(2)-dehydrogenating microorganisms, the bioprocess for preparing Δ1-3-ketosteroids, genetic engineering of 3-ketosteroid Δ1-dehydrogenases and related genes for constructing new, productive industrial strains, and microbial fermentation strategies for enhancing the product yield. Furthermore, we also highlight the recent development in the use of isolated 3-ketosteroid Δ1-dehydrogenases combined with a FAD cofactor regeneration system. Finally, in a somewhat different context, we summarize the role of 3-ketosteroid Δ1-dehydrogenase in cholesterol degradation by Mycobacterium tuberculosis and other mycobacteria. Because the enzyme is essential for the pathogenicity of these organisms, it may be a potential target for drug development to combat mycobacterial infections.

Abstract
The immune system has vital functions for homeostasis and host defense. Thus, imbalances of the immune system whether associated with allergy, hypersensitivity, or autoimmunity are of great importance, as is manifest from common diseases such as atopic diseases, urticaria, and angioedema, and drug hypersensitivity reactions. These can affect patients' quality of life and can generate high costs for health care. Epidemiological studies have provided evidence for changing patterns of allergic diseases caused by lifestyle and climate changes which have consequences for medical care. Deeper insights into the pathogenesis of allergic/immunologic diseases, combined with novel technologies, provide improved diagnostic options and treatment measures. This review will summarize novel aspects of the epidemiology, pathogenic mechanisms, as well as disease management in the fields of allergy and clinical immunology.

Abstract
Over the last decades, an increasing appearance of allergies and atopic disorders, such as asthma, dermatitis, and rhinitis, has been observed. The mechanisms of these disorders remain unclear, and therefore the development of novel therapies is limited. Current treatments are often symptomatic, nonspecific, or may have severe side effects. Further insights into the mechanisms of the underlying disease pathogenesis could reveal novel targets for treatment. In this review, we provide an update on recent basic and translational studies that offer novel insights and opportunities for the treatment of patients with atopic disorders.
