ALK-Targeted Therapies in Non-Small Cell Lung Cancer
Anaplastic lymphoma kinase (ALK)+ Non-small cell lung cancer (NSCLC), affecting about 5% of cases, is characterized by a mutation in the ALK gene, leading to poor life expectancy and a high risk of brain metastases. Unmet needs in metastatic NSCLC include the development of treatments that improve survival, reduce toxicity, and effectively address brain metastases. Evaluating Food and Drug Administration (FDA)-approved ALK inhibitors in advanced NSCLC highlights their unique effectiveness and safety profiles. Crizotinib exhibits notable benefits regarding progression-free survival (PFS) and objective response rate (ORR); however, multiple studies consistently position alectinib as the superior option. Alectinib distinguishes itself with extended PFS, increased central nervous system (CNS) activity, and excellent patient-reported outcomes.

ALK+ lung cancer: targeted inhibitors and resistance mechanisms
EML4-ALK is an oncogenic fusion protein that accounts for approximately 5% of non-small cell lung cancer cases. Targeted inhibitors of ALK are now the standard of care treatment often leading to an excellent initial response and increased overall survival. A variety of resistance mechanisms have been identified that eventually lead to relapse highlighting the need for additional treatment options for these patients.

Alkaloids and Their General Applications
Alkaloids are organic chemical compounds with a cyclic ring structure containing one or more basic nitrogen atoms. They are widely distributed in nature and are found as naturally occurring secondary metabolites in both plants and animals.

Allergen Immunotherapy
Allergen immunotherapy (AIT) is the sole disease-modifying treatment for allergic rhinitis; it prevents rhinitis from progressing to asthma and lowers medication use. AIT against mites, insect venom, and certain kinds of pollen is effective. The mechanism of action of AIT is based on inducing immunological tolerance characterized by increased IL-10, TGF-β, and IgG4 levels and Treg cell counts. However, AIT requires prolonged schemes of administration and is sometimes associated with adverse reactions. Over the last decade, novel forms of AIT have been developed, focused on better allergen identification, structural modifications to preserve epitopes for B or T cells, post-traductional alteration through chemical processes, and the addition of adjuvants. These modified allergens induce clinical-immunological effects similar to those mentioned above, increasing the tolerance to other related allergens but with fewer side effects. Clinical studies have shown that molecular AIT is efficient in treating grass and birch allergies.

Allergen Immunotherapy for Asthma
For asthma, allergen immunotherapy using house dust mite (HDM) improves clinical symptoms and airway hyperresponsiveness and decreases drug requirements. Furthermore, it has been suggested that allergen immunotherapy also has the following effects: (1) the effect can be maintained for more than a year even if the treatment is terminated, (2) the remission rate of childhood asthma can be increased, (3) new allergen sensitization can be suppressed, and (4) asthma development can be prevented if allergen immunotherapy was performed in the case of pollinosis. Allergen immunotherapy differs from conventional drug therapy, in particular the effect of modifying the natural course of allergic diseases and the effect of controlling complicated allergic diseases such as rhinoconjunctivitis.

Allergic Reactions to Vaccine Constituents
Vaccination is an essential public health measure that helps to reduce the burden of infectious diseases in children. Although vaccines have an excellent safety record and the association of severe allergic reactions is rare, public concerns about vaccine safety can lead to incomplete vaccination coverage in children with or without allergies. Therefore, it is important to understand the mechanisms and implications of allergic reactions to vaccines and define strategies to manage them to provide the safest care for vaccine recipients. Unlike drugs, which are the primary cause of immediate allergic reactions, vaccine excipients (i.e., substances used to formulate a vaccine) are the main cause of specific IgE and immediate reactions associated with vaccines. Pre-existing allergies to vaccine excipients, such as antigens, adjuvants, stabilizers, preservatives, emulsifiers, leached packaging components, residual antibiotics, cell culture materials, and inactivating ingredients, are the primary contributors to immediate allergic reactions during vaccination. In contrast, drug-related anaphylaxis is usually caused by the active drug itself rather than excipients.

Allergic Rhinitis
Nasal obstruction is a frequent disorder that interferes with the daily patient’s quality of life. The key element in the pathophysiology of the disorder is the inferior turbinate hypertrophy related to multiple conditions such as allergic rhinitis (AR). Many patients are managed using conventional drug therapies such as antihistamines, decongestants, and intranasal steroid sprays, anticholinergic agents, mast cell stabilizers, and desensitizing vaccines. When traditional therapy failed to relieve AR symptoms, surgical inferior turbinate reduction (ITR) is indicated. A vast variety of surgical techniques have been reported in the literature for AR such as resectioning, coagulating, and laser procedures.

Allergy Diagnosis Based on the Measurement of sIgE
Diagnosis of allergic diseases is a complex, multi-stage process. It often requires the use of various diagnostic tools. The in vitro diagnostics (IVD), which includes various laboratory tests, is one of the stages of this process. Standard laboratory tests include the measurement of the serum concentration of specific immunoglobulin E (sIgE) for selected allergens, full allergen extracts and/or single allergen components (molecules). The measurement of IgE sIgE to the allergen components is called molecular allergy diagnosis.

Allergy to Fungi in Veterinary Medicine
The fungal kingdom comprises ubiquitous forms of life with 1.5 billion years, mostly phytopathogenic and commensals for humans and animals. However, in the presence of immune disorders, fungi may cause disease by intoxicating, infecting or sensitizing with allergy. Species from the genera Alternaria, Aspergillus and Malassezia, as well as dermatophytes from the genera Microsporum, Trichophyton and Epidermophyton, are the most commonly implicated in veterinary medicine.
