Venom Immunotherapy Does Not Affect Survival of Patients with Malignant Tumor in Poland.

Background: Allergen immunotherapy (AIT) is a well-established and efficient method of causative treatment for allergic rhinitis, asthma and insect venom allergy. Traditionally, a recent history of malignant neoplasm is regarded as a contraindication to AIT due to concerns that AIT might stimulate tumor growth. However, there are no data confirming that the silencing of the Th2 response affects prognosis in cancer. Objectives: The aim of this study was to investigate frequency of malignant tumors in patients undergoing AIT and the association between AIT and cancer-related mortality. Patients and Methods: A group of 2577 patients with insect venom allergy undergoing AIT in 10 Polish allergology centers was screened in the Polish National Cancer Registry. Data on cancer type, diagnosis time and patients' survival were collected and compared with the general population. Results: In the study group, 86 cases of malignancies were found in 85 patients (3.3% of the group). The most common were breast (19 cases), lung (9 cases), skin (8 cases), colon and prostate cancers (5 cases each). There were 21 cases diagnosed before AIT, 38 during and 27 after completing AIT. Laplace's crude incidence rate was 159.5/100,000/year (general population rate: 260/100,000/year). During follow-up, 13 deaths related to cancer were revealed (15% of patients with cancer). Laplace's cancer mortality rate was 37.3/100,000/year (general population rate: 136.8/100,000/year). Conclusions: Malignancy was found in patients undergoing immunotherapy less often than in the general population. Patients with cancer diagnosed during or after AIT did not show a lower survival rate, which suggests that AIT does not affect the prognosis.

Safety and Efficacy of VIT against Wasp Venom in Ultra-Rush Protocols in Patients Older Than 60 Years.

BACKGROUND: Allergen immunotherapy remains a widely recognized and widely used method for the treatment of selected allergic diseases. Currently, according to the European Academy Of Allergy and Clinical Immunology (EAACI) guidelines, venom immunotherapy (VIT) may be considered for patients over 60. Nevertheless, no separate studies have confirmed the efficacy and safety of this therapy. This study aimed to evaluate the short-term effectiveness of VIT against wasp allergens in an ultra-rush protocol for older patients compared to young patients. METHODS: Among the 113 patients included in this study, 51 were older than 60 years (Group A), and 62 formed the control "young group" (age range: 18-35 years). All patients were desensitized to wasp venom using the ultra-rush protocol according to Muller and aqueous solutions of vaccines containing wasp venom. A basophil activation test (Basotest, Orpegen Pharma, Germany) and intracutaneous tests with dilutions of wasp allergen and specific IgE to extract wasp venom were performed at the start and after six months of VIT. The safety of VIT was assessed on the basis of the international Mueller scale. RESULTS: One hundred and eleven patients with confirmed wasp allergies completed six months of VIT: 51 participants over 60 years of age (Group A) and 60 young people (Group B). No systemic adverse reactions were observed during the VIT induction phase. However, large local reactions were noted in 17% of older patients and 20% of young patients at a similar level (p > 0.05). During maintenance VIT, two mild grade I systemic reactions were confirmed in young patients. These symptoms resolved spontaneously. There were no such reactions in older patients. The effectiveness of VIT was tested using BAT. There was a statistically significant reduction in CD63 reactivity in 86% of patients in Group A, and a comparable and substantial decrease in 84% of young patients in Group B. According to the BAT test, the mean reductions in the area under the curve (AUC) after six months of VIT were significant (p < 0.05) and comparable between Groups A and B: -6.52 vs. 7.21. CONCLUSIONS: VIT against wasp venom is safe and effective in short-term observation, and is comparable to that used for young patients.

Elderly Patients and Insect Venom Allergy: Are the Clinical Pictures and Immunological Parameters of Venom Allergy Age-Dependent?

Insect venom is one of the most common triggers of anaphylaxis in the elderly population. Venom immunotherapy (VIT) remains the only treatment for Hymenoptera venom allergy (HVA). However, little is known about the differences in indication for VIT in the group of patients aged 60 years and older. The objective of this study was to assess the clinical and diagnostic differences of HVA in elderly patients. The study compared data from patients aged ≥ 60 (N = 132) to data from patients aged from 11 to 60 years (N = 750) in terms of HVA severity, comorbidities, and immunological parameters, namely, intradermal testing (IDT), specific IgE (sIgE) levels against extracts and major allergenic molecules, and serum tryptase level (sBT). The severity of systemic HVA (I-IV Müller scale) did not differ between adults and seniors. However, the severity of cardiovascular reactions (IV) increased with age, while the frequency of respiratory reactions (III) decreased. No differences were found in the immunological parameters of sensitization IDT, venom-specific IgE concentrations, or sIgE against Api m 1, 2, 4, 5, and 10 between patients below and above 60 or 65 years of age. Differences were noted for sIgE against Ves v1 and Ves v5; they were higher and lower, respectively, in seniors. In the seniors group, sBT levels were higher. Elevated tryptase levels, along with the aging process, can represent a risk factor within this age category. Nevertheless, advanced age does not influence the immunological parameters of immediate HVA reactions, nor does it impact the diagnosis of HVA.

Potential Aspects of the Use of Cytokines in Atopic Dermatitis.

Atopic dermatitis (AD) is an abnormal inflammatory response in the skin to food, environmental IgE, or non-IgE allergens. This disease belongs to a group of inflammatory diseases that affect both children and adults. In highly developed countries, AD is diagnosed twice as often in children than in adults, which may possibly be connected to increased urbanization. The immune system's pathomechanisms of AD involve humoral mechanisms with IgE, cellular T lymphocytes, dendritic cells occurring in the dermis, Langerhans cells occurring in the epidermis, and other cells infiltrating the site of inflammation (eosinophils, macrophages, mast cells, neutrophils, and basophils). Cytokines are small proteins that affect the interaction and communication between cells. This review characterizes cytokines and potential aspects of the treatment of atopic dermatitis, as well as new strategies that are currently being developed, including targeting cytokines and their receptors.

Current Photodynamic Therapy for Glioma Treatment: An Update.

Research on the development of photodynamic therapy for the treatment of brain tumors has shown promise in the treatment of this highly aggressive form of brain cancer. Analysis of both in vivo studies and clinical studies shows that photodynamic therapy can provide significant benefits, such as an improved median rate of survival. The use of photodynamic therapy is characterized by relatively few side effects, which is a significant advantage compared to conventional treatment methods such as often-used brain tumor surgery, advanced radiotherapy, and classic chemotherapy. Continued research in this area could bring significant advances, influencing future standards of treatment for this difficult and deadly disease.

The Occurrence of Atopy in Patients with Isolated Spontaneous Mast Cell (or Nonallergic) Angioedema.

BACKGROUND: Isolated mast cell angioedema (MC-AE) can be divided into allergic and nonallergic (spontaneous) forms. The former is often associated with food, Hymenoptera venoms or drug allergies. This study aimed to evaluate the relationship between the occurrence of atopic diseases and the risk of angioedema. METHODS: A retrospective study analyzed 304 patients with confirmed MC-AE and 1066 controls. All were analyzed for allergic asthma (AA), atopic dermatitis (AD) and allergic rhinitis (AR) based on ICD-10 codes. In addition, total IgE and peripheral eosinophilia were calculated. RESULTS: The analyzed atopic diseases were more frequent in the group of patients diagnosed with MC-AE than in the controls: 78 (25.7%) vs. 173 (16.2%) for p < 0.01. Patients diagnosed with AD had a higher risk of MC-AE (hazard ratio (HR) = 1.48,) similar to those diagnosed with AR (HR = 1.51). However, in patients with two or three atopic comorbidities, the risk increased significantly to HR = 2.45 or HR = 4.1, respectively. There was a positive correlation between the serum total IgE concentration or eosinophilia and the risk of angioedema (p < 0.01). CONCLUSION: Patients with MC-AE had a more frequent occurrence of atopic diseases associated with inhalant allergies. This risk increased in patients with IgE-mediated polymorphic disease.

Effect of sublingual immunotherapy on clinical and laboratory autoimmunity.

Background: There still are few data on the long-term safety of sublingual immunotherapy (SLIT). The aim of this study was to assess the appearance of autoimmune diseases in patients before and after SLIT. Materials & methods: New cases of autoimmune diseases were monitored. Patients in the SLIT group (n = 816) were compared with controls (n = 1096). Results: The new incidences of autoimmune diseases in the SLIT group were lower compared with the control group: 18 (2.2%) versus 58 (5.3%); p < 0.05. Systemic lupus erythematosus, psoriasis and Hashimoto appeared much more often in the control group. Conclusion: SLIT had no significant effect on the induction of autoimmune diseases.

The therapy for allergic people is named allergen-specific immunotherapy, and one of the ways of administering this therapy is sublingual immunotherapy (SLIT), which means that the medication is kept in the mouth under the tongue. The authors assessed the safety of SLIT in terms of the risk of inducing autoimmune diseases, which means that the immune system is overactive, causing it to attack and damage the body's own tissues. Analysis of medical history for autoimmune diseases, clinical examinations and laboratory diagnostic tests were performed. SLIT did not significantly increase the incidences of autoimmune disease in the study group. SLIT is a safe therapy in long-term observation.

Progressive clinical effects of the combination omalizumab and HDM - allergen immunotherapy in asthma.

OBJECTIVE: The combination of allergen immunotherapy (AIT) and omalizumab is used to treat patients at risk of anaphylaxis. There is currently a very little evidence that this combination increases the effectiveness of AIT in patients with inhalant allergies. The study aimed to evaluate the effectiveness of HDM-SCIT therapy (injection immunotherapy for house dust mites) in combination with omalizumab in treating HDM-induced asthma. METHODS: This study was a placebo-controlled, randomized, multicenter trial including 82 patients with HDM-driven mild to moderate asthma. Omalizumab alone (A), HDM SCIT + omalizumab (B), SCIT alone (C), or placebo (D) for 24 months were applied. All patients received asthma treatment in accordance with GINA recommendations. The treatment efficacy was defined by a reduction in the daily dose of inhaled steroids (ICS) and a reduction in the number of asthma exacerbations (AX). RESULTS: After 24 months of therapy, a statistically significant reduction in the daily doses of ICS in groups A and B was observed (p = 0.021 and p = 0.008). Daily ICS reduction was considerably more significant in group B (p = 0.01). During 24 months of observation, the AX was significantly reduced in all study groups, with the greatest significant difference observed between groups A and B and groups C and D (placebo) as follows: 0.42 patient/per year vs. 0.39 vs. 0.84 vs. 0.91 (p = 0.023). CONCLUSION: The combination of HDM SCIT and omalizumab is significantly and progressively reducing ICS use and AX in a 24-month study. The combination is significantly more effective than the single treatments or placebo.

Long-term benefit after allergen immunotherapy to HDM in elderly patients with allergic rhinitis.

Introduction: Allergen immunotherapy (AIT) is an effective therapy for allergic rhinitis and may have long-term benefits. However, these benefits have not been strictly defined for older people. Aim: The evaluation of the effectiveness of AIT in patients over 60 with allergic rhinitis and house dust mites (HDM) allergy over a period of 7 years was performed. Material and methods: Patients after three years of HDM-AIT were observed to assess the sustained clinical effect of treatment. The average adjusted symptom score (AAdSS) and sIgG4 were monitored for 7 years after sublingual (SLIT) and injection AIT (SCIT). Results: After 3 years of HDM-AIT, a significant clinical effect was observed in the group after SLIT and SCIT based on AAdSS compared to the baseline and the placebo group (p < 0.05). After 7 years of follow-up, there was a sustained trend of decrease in clinical symptoms in desensitized patients relative to placebo. Serum sIgG4 was constantly present in all desensitized patients. Conclusions: AIT may be beneficial for treating seniors with allergic rhinitis and allergies to house dust mites.

Molecular profiling of allergen-antibody IgE might decide about the efficacy of allergen immunotherapy in a patient with atopic dermatitis and allergy to house dust mites.

Introduction: Allergen immunotherapy (AIT) has no clear recommendation for atopic dermatitis (AD). Aim: To evaluate the effect of AIT on house dust mites (HDM) in AD patients sensitised to HDM with different baseline molecular profiles of antigens. Material and methods: In this placebo-controlled study, 61 patients with moderate-to-severe AD allergy symptoms and HDM allergy were included. They received a 12 months' AIT with the use of HDM allergen extract or placebo. The authors adopted their AD improvement criterion after 1 year of AIT as a reduction of all examined indicators by at least 50% from the baseline for %BSA, TMS, and EASI scores. Additionally, the influence of individual HDM molecules on the final AIT effect was analysed. Results: Finally, from the 24 desensitised patients, 15 achieved a positive expected effect after 12 months of HDM AIT. None of the patients who received a placebo had an improvement in AD of at least 50% after 1 year of follow-up. Patients with polysensitisation less frequently achieved the expected HDM AIT effect than patients monosensitised to mites (p < 0.05). The presence of sensitisation to rDer p 1 (odds ratio = 4.35, 95% CI: 4.01-4.56) and/or rDer p 2 (OR = 2.16, 95% CI: 1.98-2.33) and/or rDer f 2 (OR = 1.41, 95% CI: 1.55-1.78) molecules significantly increased the efficacy of AIT. HDM AIT could be helpful for patients with moderate-to-severe AD and sensitised to HDM as an add-on therapy. Various HDM molecules may affect the effectiveness of the expected AIT effect. The presence of sensitisation to rDer p 1 (OR = 4.35, 95% CI: 4.01-4.56) and/or rDer p 2 (OR = 2.16, 95% CI: 1.98-2.33) and/or rDer f 2 (OR = 1.41, 95% CI: 1.55-1.78) molecules significantly increased the efficacy of AIT. Conclusions: HDM AIT could be helpful for patients with moderate-to-severe AD and sensitised to HDM as an add-on therapy. Various HDM molecules may affect the effectiveness of the expected AIT.

The vicious circle effect: stress as effect and cause in patients with psoriasis.

Psoriasis is a common immune-mediated, chronic inflammatory disease, causing adverse effects on patients' quality of life and disease burden. In psychodermatology, psoriasis is included both in the group of dermatological diseases, in which the psychophysiological background plays a key role, and in dermatoses being a potential source of emotional disturbances or being a trigger for the development of secondary mental disorders. A comprehensive view of the patient with psoriasis, not only from the point of view of skin disease, but also as a result of a wide impact of stress, including low self-esteem and inappropriate social perception may have a key influence on improvement of quality of life of these patients.

Clinical outcomes of AIT in the elderly population.

PURPOSE OF REVIEW: This review aims to present the current knowledge on the effectiveness and safety of allergen immunotherapy (AIT) in patients over 60 years of age with inhalant allergies. RECENT FINDINGS: Over the last 10 years, the problem of immunoglobulin E allergy in seniors has been noticed by many authors. At the same time, in the 1990s, trials of desensitization to selected inhalant allergens were started, obtaining evidence of the effectiveness of AIT, both with the use of sublingual immunotherapy (SLIT) and injection immunotherapy (SCIT), in patients over 60 years of age with allergic rhinitis. Such data have been confirmed for AITs for grasses, birch, and house dust mites. Currently, these patients are being monitored to assess the long-term effect of AIT. All available observations confirm the high safety of AIT in seniors. SUMMARY: Seniors with allergic rhinitis or asthma may qualify for AIT if they do not have contraindications. These patients can experience a sustained clinical benefit even after completing AIT treatment. Studies indicate that injectable and sublingual routes of administration may be effective in this age group, provided the suspect allergen is accurately diagnosed.

The aspects of local allergic rhinitis in Polish children and adolescents.

Introduction: Local allergic rhinitis (LAR) is one of the endotypes of rhinitis which occurs commonly in different age groups. Aim: To present the occurrence and characteristics of LAR in Polish children and adolescents. Material and methods: In the study protocol, three hundred sixty-one patients aged 5-17 with chronic rhinitis were included from 8 centres in Poland. Medical history and diagnostic procedures were performed with aeroallergens: skin prick tests, allergen-specific serum IgE and nasal provocation tests. In addition to LAR, allergic rhinitis (AR), dual allergic rhinitis (DUAL) and non-allergic rhinitis (NAR) were explored and compared. Results: LAR was confirmed in 21% of patients, systemic allergic rhinitis (SAR) in 43.9%, DUAL in 9.4% and NAR in 33.9% of patients. Based on nasal provocation test (NPT), allergy to HDM prevailed in the LAR group (68%), grass in the SAR group (58%), and grass and HDM in the DUAL group (32% and 64%). Girls were prevalent in the LAR group, and severe rhinitis and asthma were more common than other endotypes (p < 0.05). Conclusions: LAR is a common disease in children and adolescents and is often associated with severe rhinitis and frequently coexists with asthma.

Acquired Angioedema in Selected Neoplastic Diseases.

Background and Objectives. Acquired angioedema is a relatively common revelation accompanying some diseases such as autoimmune or cancer. The study aimed to assess the incidence of one subtype of angioedema-C1-INH-AAE (acquired angioedema with C1 inhibitor deficiency). Material and methods. The study was retrospective and based on 1 312 patients with a final diagnosis of breast cancer, colorectal cancer, or lung cancer: 723 women and 589 men with a mean age of 58.2 ± 13.5 years. The cancer diagnosis according to the ICD (International Classification of Diseases)-10 code, medical history including TNM (Tumour, Node, Metastasis) staging, histopathology, and assessment of the occurrence of C1-INH-AAE angioedema were analysed. Results. C1-INH-AAE occurred more often in patients with cancer than in the control group, as follows: 327 (29%) vs. 53 (6%) for p < 0.05. C1-INH-AAEs were observed most often in the group of patients diagnosed with breast cancer compared to colorectal and lung groups: 197 (37%) vs. 108 (26%) vs. 22 (16%) (p < 0.05). A higher incidence of C1-INH-AAE was observed in the early stages of breast cancer. However, there was no relationship between the occurrence of C1-INH-AAE and the BRCA1 (Breast Cancer gene 1)/BRCA2 (Breast Cancer gene 2) mutation or histopathological types of breast cancer. Conclusion. Angioedema type C1-INH-AAE occurs more often in patients with selected neoplastic diseases, especially in the early stages of breast cancer.

The Effect of Biological Treatment on Stress Parameters Determined in Saliva in Patients with Severe Psoriasis.

Background and objectives: In psoriatic patients, stress is the most common aggravating factor. Despite the use of quality-of-life assessment questionnaires, diagnosing stress in psoriatic patients is not a flawless procedure. This study aimed to assess the usefulness of potential stress biomarkers in saliva for monitoring the treatment of psoriasis. Materials and methods: A total of 104 adult patients with severe psoriasis were included and randomly treated via biological treatment or symptomatic therapy: 84 received biological treatment, with 20 formed a control group receiving symptomatic therapy. The administered biological treatment was adalimumab, whilst in controls calcipotriol/betamethasone dipropionate topical gel and emollients were used. Patients were monitored monthly with a dermatological examination and the dispensing of a biological drug. During each of the four visits, the severity of the disease was assessed (PASI, BSA, and DLQI), and a sample of the patient's saliva was taken. In all the participants, the saliva concentrations of immunoglobulin A (sIgA), α-amylase (sAA), and chromogranin A (CgA) were measured. Results: The majority of patients in both the study and control groups achieved clinical improvement, though favoring the group receiving biological treatment. The concentration of sIgA in the saliva was constantly increasing in the study group during subsequent visits (Fr = 27.26; p < 0.001). Meanwhile, there were no statistically significant changes in the control group during the same follow-up period (Fr = 6.66; p = 0.084). Levels of sAA underwent statistically significant changes in both groups (Fr = 58.02; p < 0.001-study group and Fr = 13.74; p = 0.003-control group). In the study group, a steady, statistically significant increase in sAA was observed from the first to the third visit. In the study group, a downward trend in CgA concentration was observed. In the control group, no significant differences in the level of CgA were obtained. Conclusions: sIgA, sAA, and CgA are potential markers of the severity of psoriasis and the associated stress reaction. Based on the presented observations, only sIgA and CgA seem to be valuable biomarkers for monitoring the effectiveness of the systemic treatment of psoriasis.

Adding a biologic to allergen immunotherapy increases treatment efficacy.

Background: The application of allergen immunotherapy (AIT) in combination with biological agents has been found to increase both the safety and efficacy of the desensitisation procedure in patients with food and insect venom allergy. The aim of our study was to compare the effectiveness of AIT in patients with house dust mite (HDM)-driven asthma treated with and without omalizumab. Materials and methods: The study was a placebo-controlled, three-armed, randomised, parallel-group, multicentre trial that included 52 patients with HDM-driven asthma. Only patients with monosensitisation to HDM were included. The study compared three patterns of therapy: omalizumab alone, HDM subcutaneous immunotherapy (SCIT-HDM)+ omalizumab, and SCIT alone. The main outcomes were evaluate the Asthma Control Questionnaire (ACQ) score, number of asthma exacerbations and reduction in the daily dose of inhaled steroids during 12 months of observation. Results: All variants of therapy led to significantly improved ACQ scores and reduction of asthma exacerbations in all study groups after 12 months of treatment. A statistically significant reduction in the daily doses of inhaled corticosteroids in the group with omalizumab alone (650±150 µg versus 500±50 µg for p=0.003) or SCIT-HDM+omalizumab (550±250 µg versus 375±75 µg for p=0.001) was observed, favouring the latter group. Conclusion: The efficacy of AIT for HDM-driven asthma is significantly increased by the combination of allergen vaccine with omalizumab.

Monitoring of molecular profiling of allergen-antibody responses in HDM-immunotherapy patients.

Among the potential hazards of HDM immunotherapy (AIT) with HDM allergenic extracts is the possible initiation of de novosensitizations caused by a lack of complementarity between a given HDM vaccine's content and a patient's molecular sensitization profile. To investigate whether immunotherapy with HDM extracts affects changes in the profile of sensitizations to allergens contained in the extract and whether neosensitizations occur. Serum samples from patients with HDM allergies (N=63) who received 1 year of treatment with subcutaneous AIT were tested for allergen-specific IgE (sIgE) reactivity to 7 microarrayed HDM allergen molecules (Der p 1, 2,10,11,23; D far 1 and 2) with ImmunoCAP. The HDM non-AIT patients (N=22) who did not receive immunotherapy constituted the study's control group. The obtained data were analysed at baseline and after 6 and 12 months. In the HDM-AIT group, no neosensitizations after 6 and 12 months of immunotherapy were reported. Conversely, in the HDM non-AIT group, only neosensitizations to Der p 10 were observed. In the study group, sIgE levels against the HDM extract of D. pteronyssinus, D. farinae, rDer p 1, rDer p 2 and Der f 2 decreased after 12 months of AIT (p< .05). SIgE levels against Der f 1, Der p 10, 11 and 23 remained unchanged in the course of 12 months of immunotherapy. In patients with allergic rhinitis with or without concomitant HDM-induced asthma treated with HDM AIT for 12 months, no neosensitizations related to the examined HDM molecules were observed.

Immunological differences between atopic dermatitis, psoriasis, and their combination in adult patients.

OBJECTIVES: The simultaneous occurrence of psoriasis (PS) dominated by Th1 lymphocytes and atopic dermatitis (AD) driven by Th2 cells is rare. This study analyzed a group of adult patients with concomitant PS and AD (ADPS) and compared the cytokine profiles of these patients with those of subjects with homogenous PS or AD and healthy controls. MATERIALS AND METHODS: All patients underwent dermatological examinations, including assessment of Scoring Atopic dermatitis (SCORAD) index and Psoriasis Area Severity Index (PASI) scores, TNF-α, IFN-γ, Il-2, Il-4, Il-5, Il-6, Il-8, Il-12, I-17A, Il-18, Il-22, Il-33, and T. There were 39 patients with a diagnosis of ADPS, 45 patients with PS, 47 patients with AD, and 42 healthy controls. RESULTS: Patients with ADPS were mainly men with a proportional distribution of skin lesion areas. Significant differences were observed in the concentration of Il-17A between patients with ADPS and those with AD or PS and controls, which were as follows: 16.1 ± 5.4, 5.8 ± 2.1, 5.0 ± 3.1, and 3.3 ± 1.8 pg/mL, respectively. In conclusion, AD and PS might coexist as a combination disease. The role of T helper 17 cells may be more essential than previously thought.

Omalizumab added to allergen immunotherapy increased the effect of therapy in patients with severe local allergic rhinitis.

BACKGROUND: Allergen immunotherapy (AIT) is effective in patient with local allergic rhinitis (LAR). However, AIT may not always achieve the optimal treatment effect. OBJECTIVE: To present short study with clinical cases of LAR combined therapy with sublingual immunotherapy (SLIT) and omalizumab in patients with house dust mite (HDM) allergy and compared it to therapy with omalizumab alone. METHODS: Patients with severe LAR and hypersensitivity to HDMs were included. SLIT for HDMs was launched in a perennial protocol using SQ-HDM SLIT tablets with omalizumab. The total rhinitis symptom score (TRSS), total medication score (TMS) and combined total score (CTS) were assessed after one year. RESULTS: After 12 months, significant improvements in all analyzed parameters in the patients on SLIT+ omalizumab therapy were observed: a reduction in the TRSS from 1.21 ± 0.33 to 0.6 ± 0.28 (p < .05), a reduction in the TMS from 2.25 ± 1.05 to 0.88 ± 0.31 (p < .05) and a reduction in the CTS from 3.46 ± 0.57 to 1.48 ± 0.51 (p < .05). This improvement in TRSS, TMS also in CTS was significantly greater than in the rest of the group with SLIT alone or omalizumab alone. CONCLUSION: Omalizumab may be a valuable treatment that increases the effectiveness of immunotherapy in patients with severe LAR.
