Objective: To report two cases of chronic neutropenic states successfully treated with granulocyte colony stimulating factor (G-CSF).
Clinical Features: A 23-year-old man with severe congenital cyclic neutropenia causing lifelong recurrent infections and consequent debilitation presented with intractable infected leg ulcers. A 56-year-old man with acquired idiopathic neutropenia presented with severe perianal infection and sepsis.
Intervention And Outcome: Both patients were successfully treated with recombinant G-CSF.
Conclusion: G-CSF is an agent with major clinical potential for the therapy of primary neutropenic states.

Infection with Influenza A virus (IAV) induces severe inflammatory responses and lung injury, contributing significantly to mortality and morbidity rates. Alterations in the microbial composition of the lungs and intestinal tract resulting from infection could influence disease progression and treatment outcomes. Xiyanping (XYP) injection has demonstrated efficacy in clinical treatment across various viral infections.

Autoimmune pulmonary alveolar proteinosis (aPAP), which accounts for >90% of all cases of PAP, is a rare lung disease mediated by granulocyte-macrophage colony-stimulating factor (GM-CSF) autoantibodies that block GM-CSF signalling, leading to reduced surfactant clearance causing abnormal accumulation of alveolar surfactant and impaired gas exchange [1-3]. The current standard of care for aPAP is whole-lung lavage (WLL), which is invasive, resource intensive, carries procedural risk, does not address the underlying cause of disease and often must be repeated regularly [4]. Hence, there is a therapeutical need to address the underlying pathophysiology of the disease.

The immunoglobulin E (IgE) receptor FcεRI (Fc epsilon RI) plays a crucial role in allergic reactions. Recent studies have indicated that the interaction between FcεRIβ and the downstream protein phospholipase C beta 3 (PLCβ3) leads to the production of inflammatory cytokines. The aim of this study was to develop small molecules that inhibit the protein-protein interactions between FcεRIβ and PLCβ3 to treat allergic inflammation.

Purpose Of Review: Febrile neutropenia as a complication of cytotoxic chemotherapies, remains a major event in the medical journey of hematology and oncology patients. In this review, we are trying to review the new elements and highlights that are shaping febrile neutropenia in nowadays.
Recent Findings: Introduction of risk-stratification, expanded use of granulocyte-colony stimulating factor and oral treatment for selected patients and rapid administration of antibiotics revolutionized the treatment of febrile neutropenia.

Neutrophil elastase () mutations are the most common cause of cyclic (CyN) and congenital neutropenia (SCN), two autosomal dominant disorders causing recurrent infections due to impaired neutrophil production. Granulocyte colony-stimulating factor (G-CSF) corrects neutropenia but has adverse effects, including bone pain and in some cases, an increased risk of myelodysplasia (MDS) and acute myeloid leukemia (AML). Hematopoietic stem cell transplantation is an alternative but is limited by its complications and donor availability.
