Thromboinflammation in ischemic cerebrovascular patients with the JAK2V617F mutation.

Background: The JAK2V617F mutation is a driver of Philadelphia chromosome-negative myeloproliferative neoplasms (MPN) and is also implicated in cardiovascular diseases. Thrombosis in MPN involves JAK2V617F-associated platelet activation and endothelial dysfunction, all potentially influenced by chronic inflammation. Whether the mutation affects thromboinflammatory markers similarly in non-MPN patients remains unclear.

Changes in gut microbiota predict neutropenia after induction treatment in childhood acute lymphoblastic leukemia.

Delayed neutrophil recovery during acute lymphoblastic leukemia (ALL) treatment increases risk of infection and causes delay in chemotherapy. Emerging evidence implicates the gut microbiota in neutrophil reconstitution after chemotherapy. We explored the interplay between the gut microbiota and neutrophil dynamics, including neutrophil chemoattractants, in 51 children with newly-diagnosed ALL.

Cytokine stability in chronic wound fluid and its association to fibroblast proliferation.

Cytokines are commonly deregulated in venous leg ulcers. We have investigated cytokine stability by incubating sterile-filtered wound fluids from chronic venous leg ulcers in vitro. Incubation of wound fluids for 24 h at 37°C decreased IL-1β levels by 88% and TNF-α levels by 64%.

Intestinal mucositis, systemic inflammation and bloodstream infections following high-dose methotrexate treatment in childhood acute lymphoblastic leukaemia: Comparison between the NOPHO ALL 2008 protocol and the ALLTogether1 protocol.

Severe intestinal mucositis (IM) increases the risk of bloodstream infections (BSI) and inflammatory toxicity during acute lymphoblastic leukaemia (ALL) induction treatment. However, the implications of IM in subsequent ALL therapy phases after achieving remission remain unknown. This study investigated the relationship between IM (measured by plasma citrulline and the chemokine CCL20) and the development of BSI and systemic inflammation (reflected by C-reactive protein, CRP) in children with ALL during high-dose methotrexate (HDMTX) treatment, an important part of ALL consolidation therapy.

Evaluation of circulating IgG antibodies against Porphyromonas gingivalis or its gingipains as serological markers of periodontitis and carriage of the bacterium.

Background: Increasing evidence indicates that periodontitis contributes to systemic low-grade inflammation. Porphyromonas gingivalis is strongly associated with periodontitis, and antibodies against the bacterium may be used as a serological proxy to account for periodontal status, when studying diseases associated with periodontitis. The aim of the present study is to identify an easily accessible and reliable serological biomarker for determination of periodontal status and oral carriage of the bacterium.
