Pneumonia in Patients with Chronic Lymphocytic Leukemia Treated with Venetoclax-Based Regimens: A Real-World Analysis of the Polish Adult Leukemia Group (PALG).

Background/objectives: Patients with chronic lymphocytic leukemia (CLL) are susceptible to infections that can affect their clinical outcomes.

Aims: The aims of this study were to assess the following: (1) the incidence of pneumonia in CLL patients treated with venetoclax-based regimens in a real-world setting, (2) the risk factors for event-free survival (EFS), and (3) overall survival (OS).

Methods: This multicenter study included 322 patients from eight centers.

[Allergens of mites].

Mite allergens belong to the group of inhalant allergens and represent antigenic substances which are particutlarly important in the pathogenesis of respiratory system diseases and skin diseases. The most common diseases associated with chronic exposure to these aeroallergens include: allergic rhinitis, bronchial asthma and atopic dermatitis. Mite allergens are simple proteins or glycoproteins with different molecular structures and various biochemical functions.

[Influence of oxidative stress on tissue regeneration].

The redox reactions involving oxidants and antioxidants play a key role in many biochemical pathways and cellular biosynthesis and regulation processes at the molecular level. Normally, there is the balance between oxidative and reductive processes in the organism. If oxidative processes are prevalent, it will result in oxidative stress.
