Abstract
Kawasaki disease is an immune-mediated acute, systemic vasculitis and is the leading cause of acquired heart disease in children in the developed world. Bifidobacterium (BIF) is one of the dominant bacteria in the intestines of humans and many mammals and is able to adjust the intestinal flora disorder. The Caco-2 cell monolayers were treated with tumor necrosis factor-α (TNF-α) at 10 ng/ml for 24 h to induce the destruction of intestinal mucosal barrier system. Cells viability was detected through Cell Counting Kit-8 assay. Cell apoptosis was measured by flow cytometry and the expression of apoptosis related proteins was also detected through Western blot. The level of pro-inflammatory cytokines interleukin-6 (IL-6) and IL-8 was detected through ELISA, Western blot and qRT-PCR, respectively. Transepithelial electrical resistance (TEER) assay was conducted to value the barrier function of intestinal mucosa. Cell autophagy and NF-κB and p38MAPK pathways associated proteins were examined through Western blot. In the absence of TNF-α treatment, cell viability and apoptosis showed no significant change. TNF-α decreased cell viability and increased cell apoptosis and BIF treatment mitigated the TNF-α-induced change. Then, we found that BIF treatment effectively suppressed TNF-α-induced overexpression of IL-6 and IL-8. Besides, the results of TEER assay showed that barrier function of intestinal mucosa which was destroyed by TNF-α was effectively recovered by BIF treatment. In addition, TNF-α induced autophagy was also suppressed by BIF. Moreover, TNF-α activated NF-κB and p38MAPK signal pathways were also blocked by BIF, SN50 and SB203580. Our present study reveals that BIF plays a protective role in TNF-α-induced inflammatory response in Caco-2 cells through NF-κB and p38MAPK pathways.

Rheumatol Int 2019; 39:1955-1960. [PMID: 31549188 DOI: 10.1007/s00296-019-04448-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2019] [Accepted: 09/16/2019] [Indexed: 11/30/2022]
Abstract
DNI is the immature granulocyte fraction provided by a blood cell analyzer, which is determined by subtracting the fraction of mature polymorphonuclear leukocytes from the sum of myeloperoxidase-reactive cells. We aimed to evaluate the role of Delta-neutrophil index (DNI) in cardiac prognosis prediction in children with Kawasaki disease (KD). Medical records of 193 patients were retrospectively reviewed. The values of DNI, white blood cells, erythrocyte sedimentation rate, the percent of polymorphonuclear leucocytes, C-reactive protein, aspartate transaminase, alanine aminotransferase, total bilirubin data of children with KD were analyzed. Also, sex and age of children were compared. The value of DNI was higher in children with cardiac complications [median 0.8 (0-0.26) vs 5.3 (3.55-8.95); P < 0.001]. The ROC curves showed that DNI was a better predictor of cardiac complications than other parameters. The best cutoff value for DNI to predict cardiac complications was 5.55% with sensitivity of 80% and specificity of 82% (AUC 0.883, 95% confidence interval [CI] 0.807-0.959, P < 0.05). DNI could serve as a facile and useful marker to predict cardiac complications in children with KD, as it is included in a routine complete blood count.
