031). Conclusions Patients with JIA have generally lowered pain threshold to mechanical stimulus, which suggests an effect of JIA on nocicepton-modulating processes.Some patients with pancytopenia do not conform to any diagnostic criteria of known haematological or non-haematological diseases; however, they respond well to corticosteroid, high-dose intravenous immunoglobulin and rituximab treatment. This abnormality is termed immunorelated pancytopenia (IRP). Later studies indicated that IRP might be a kind of autoimmune disease in which T helper (Th) type 2 cell function is enhanced, resulting in the hyperfunction of B lymphocytes, which then produce excess autoantibodies that attack the bone marrow (BM) and cause cytopenia. Hypofunction of regulatory T (Treg) cells and enhanced Th17 cell function, an elevated percentage of plasmacytoid dendritic cells (pDCs) and a decreased percentage of natural killer (NK) cells help to promote the process. Moreover, increased expression of a synergistic stimulator of B lymphocytes, CD70 and the reactive overexpression of the BCR inhibitory coreceptor CD22 also support this claim. Candidate autoantigens targeted by autoantibodies on haematopoietic cell membranes have also been reported in IRP. This review is focused on studies that demonstrate the role of immune responses in the pathogenesis of IRP. Current diagnostic criteria and treatments for IRP are also referenced to provide a thorough understanding. Distinguishing IRP from idiopathic cytopenias of undetermined significance (ICUS) and other haematological disorders, for example myelodysplastic syndrome (MDS), aplastic anaemia (AA), paroxysmal nocturnal hemoglobinuria (PNH) and Evans syndrome, may help patients with pancytopenia benefit from proper treatment. Further studies are required to achieve new insight into the pathophysiology of IRP with regard to the immune system, which will be instrumental for the development of novel therapies for inhibiting disease initiation and/or progression.Background Disease severity is important when considering genes for inclusion on reproductive expanded carrier screening (ECS) panels. We applied a validated and previously published algorithm that classifies diseases into four severity categories (mild, moderate, severe, and profound) to 176 genes screened by ECS. Disease traits defining severity categories in the algorithm were then mapped to four severity-related ECS panel design criteria cited by the American College of Obstetricians and Gynecologists (ACOG). Methods Eight genetic counselors (GCs) and four medical geneticists (MDs) applied the severity algorithm to subsets of 176 genes. MDs and GCs then determined by group consensus how each of these disease traits mapped to ACOG severity criteria, enabling determination of the number of ACOG severity criteria met by each gene. Results Upon consensus GC and MD application of the severity algorithm, 68 (39%) genes were classified as profound, 71 (40%) as severe, 36 (20%) as moderate, and one (1%) as mild. After mapping of disease traits to ACOG severity criteria, 170 out of 176 genes (96.6%) were found to meet at least one of the four criteria, 129 genes (73.3%) met at least two, 73 genes (41.5%) met at least three, and 17 genes (9.7%) met all four. Conclusion This study classified the severity of a large set of Mendelian genes by collaborative clinical expert application of a trait-based algorithm. Further, it operationalized difficult to interpret ACOG severity criteria via mapping of disease traits, thereby promoting consistency of ACOG criteria interpretation.Background Although vitamin D3 deficiency is considered as a risk factor for periodontitis, supplementation during periodontal treatment has not been shown to be beneficial to date. Human periodontal ligament cells (hPDLCs) are regulated by vitamin D3 and play a fundamental role in periodontal tissue homeostasis and inflammatory response in periodontitis. The aim of this study is to investigate possible alterations of the vitamin D3 activity in hPDLCs under inflammatory conditions. Methods Cells isolated from six different donors were treated with either 1,25(OH)2 D3 (0 to 10 nM) or 25(OH)D3 (0 to 100 nM) in the presence and absence of ultrapure or standard Porphyromonas gingivalis lipopolysaccharide (PgLPS), Pam3CSK4, or interferon-γ for 48 hours. Additionally, nuclear factor (NF)-κB inhibition was performed with BAY 11-7082. The bioactivity of vitamin D in hPDLCs was assessed based on the gene expression levels of vitamin D receptor (VDR)-regulated genes osteocalcin and osteopontin. Additionally, VDR and CYP27B1 expression levels were measured. Results The vitamin D3 -induced increase of osteocalcin and osteopontin expression was significantly decreased in the presence of standard PgLPS and Pam3CSK4, which was not observed by ultrapure PgLPS. Interferon-y had diverse effects on the response of hPDLCs to vitamin D3 metabolites. NF-kB inhibition abolished the effects of standard PgLPS and Pam3CSK4. Standard PgLPS and Pam3CSK4 increased VDR expression in the presence of vitamin D3 . CYP27B1 expression was not affected by vitamin D3 and inflammatory conditions. Conclusions This study indicates that the transcriptional activity of VDR is diminished under inflammatory conditions, which might mitigate the effectiveness of vitamin D3 supplementation during periodontal treatment.Background Implants with platform-switching (PS) design have been demonstrated to reduce marginal bone loss. However, the influence on peri-implant soft tissue healing is unclear. This study was designed to investigate its effect on peri-implant soft tissue healing after implant uncovery. Methods Non-smokers needing two implants in different quadrants were recruited in this study. For each individual, one PS and one platform-matching (PM) implants were placed using 2-stage protocol. Following 2-8 months of healing, all implants were uncovered and connected to the corresponding healing abutments. selleckchem Clinical measurements and peri-implant crevicular fluid (PICF) were taken at 1-, 2-, 4-, and 6-week after 2nd stage surgery. The cytokine concentrations in PICF were analyzed. Peri-implant mucosa (1 × 2 × 2mm) was harvested around the healing abutment for the analysis of gene expression at uncovery and 6-week post-uncovery. Results 18 participants (9 males; 51.7±14.9 years) were recruited. Compared to PM, PS showed significantly lower probing depth (PD) at 1- and 2-week as well as modified sulcus bleeding index (mSBI) at 1-, 4- and 6-week (P less then 0.
