In vivo study of pro-inflammatory cytokine changes in serum and synovial fluid during treatment with celecoxib and etoricoxib and correlation with VAS pain change and synovial membrane penetration index in patients with inflammatory arthritis.

Objectives: To determine the impact of celecoxib and etoricoxib therapy on serum and synovial fluid levels of IL-1β, IL-6, TNF-α, sTNFR1, sTNFR2 and IL-1Ra in patients with inflammatory arthritis. To determine the correlation between cytokine changes and synovial membrane penetration index of the study drugs, and pain VAS change.

Methods: Fifty-one patients with inflammatory synovial fluid accumulation in a knee joint (33 women), randomized on 3 groups of 17 each: 100 mg b.

NK and NKT Cell Depletion Alters the Outcome of Experimental Pneumococcal Pneumonia: Relationship with Regulation of Interferon-γ Production.

Background. Natural killer (NK) and natural killer T (NKT) cells contribute to the innate host defense but their role in bacterial sepsis remains controversial. Methods.

Chemokine CXCL-1: activity in the vitreous during proliferative vitreoretinopathy.

The aim of this study was to investigate CXCL-1 chemokine levels in the vitreous during rhegmatogenous retinal detachment (RRD) with and without proliferative vitreoretinopathy (PVR) and identify possible correlations with clinical parameters (extent and duration or RRD and PVR grade). Vitreous samples from patients with primary RRD with or without PVR were collected and assayed using a double antibody enzyme-linked immunosorbent assay (ELISA). Eleven vitreous samples from organ donors were employed as a control group.

An unusual case of Streptococcus agalactiae meningitis in a patient with sys-temic lupus erythematosus.

Background: (group B Streptococcus) is a major cause of sepsis and meningitis in neonates and an important cause of invasive disease in adults.

Case Description: We describe an unusual case of fatal bacterial meningitis caused by in a young man suffering from systemic lupus erythematosus for over 20 years. The young man was transferred intubated in AHEPA University Hospital in a coma; twenty-four hours upon arrival and despite intense invasive treatment, he died from multiple organ failure.
