Background: Glucocorticoids have been used to treat asthma since the 1950s; however, their adverse systemic effects have limited their duration of use and dosage. Unfortunately, many patients with severe asthma often require oral glucocorticoids in addition to inhaled glucocorticoids. Alternatives to glucocorticoids have been sought with mixed success. Recently, lidocaine has been added to the list of potent glucocorticoid sparing agents for the treatment of severe asthma.
Objective: We report the first group of pediatric patients with severe asthma treated with nebulized lidocaine.
Methods: The study was performed in an open manner with 6 severely asthmatic patients followed in the Pediatric Allergy and Immunology Section, Mayo Clinic. The only intervention was the institution of nebulized lidocaine (0.8 mg/kg/dose to 2.5 mg/kg/dose t.i.d to q.i.d). The average daily steroid requirement was followed during the administration of the nebulized lidocaine.
Results: During a mean of 11.2 months of therapy (range 7 to 16 months) 5 of the 6 patients completely discontinued their oral glucocorticoids within an average time of 3.4 months (range 1 to 7 months).
Conclusions: After further study, lidocaine may prove to be the first non-toxic, steroid alternative to patients with severe steroid-dependent asthma.

Extracorporeal cardiopulmonary resuscitation (ECPR) is a complex, life-saving procedure that uses mechanical support for patients with refractory cardiac arrest, representing the pinnacle of extracorporeal membrane oxygenation (ECMO) applications. Effective ECPR requires precise patient selection, rapid mobilization of a multidisciplinary team, and skilled cannulation techniques. Establishing a program necessitates a cohesive ECMO system that promotes interdisciplinary collaboration, which is essential for managing acute cardiogenic shock and severe pulmonary failure.

Background: Human milk (HM) is recognized as an ideal source of nutrition for newborns; as a result, its multiple bioactive molecules can support the growth of healthy newborns and reduce the risk of mortality and diseases such as asthma, respiratory infections, diabetes (type 1 and 2), and gastrointestinal disorders such as ulcerative colitis and Crohn's disease. Furthermore, it can reduce the severity of necrotizing enterocolitis (NEC) in preterm infants. Moreover, human milk oligosaccharides (HMOs) present in breast milk show an immunomodulatory, prebiotic, and neurodevelopmental effect that supports the microbiota-gut-brain axis.

Purpose Of Review: Regulatory B cells (Bregs) are a key component in the regulation of the immune system. Their immunosuppressive function, which includes limiting the inflammatory cascade, occurs through interactions with other immune cells and the secretion of cytokines, primarily IL-10. As knowledge about B cells continues to expand, their diversity is becoming more recognized, with many subpopulations identified in both human and animal models.

Background: Genetic factors play a role in asthma severity. However, low- and middle-income countries have minimal contribution to genomic asthma research. The current study investigates the influence of an important genetic asthma region (6p21) on severe asthma in a cohort of asthmatics in Pakistan.

Eosinophils are central inflammatory cells in asthma; however, a portion of patients with chronic obstructive pulmonary disease (COPD) have blood or sputum eosinophilia, a condition termed eosinophilic COPD (eCOPD), which may contribute to the progression of the disease. We hypothesize that eosinophilic inflammation in eCOPD patients is related to Type 2 (T2)-high inflammation seen in asthma and that serum mediators might help us to identify T2-high inflammation in patients and choose an appropriate personalized treatment strategy. Thus, we aimed to investigate ten serum levels of T2-high inflammation mediators in eCOPD patients and compare them to severe non-allergic eosinophilic asthma (SNEA) patients.
