概括

患有囊性纤维化 (CF) 的儿童的早期肠道微生物组模式可以预测体重状况,即使使用调节剂治疗. 特定的微生物特征与超重风险增加有关,这表明早期干预的潜力.

科学领域:

微生物组研究的研究.
儿科卫生保健儿科卫生保健
囊性纤维化 (CF) 研究研究

背景情况:

肠道微生物群对于儿童的成长至关重要.
患有囊性纤维化 (CF) 的儿童经常经历生长挑战.
高效的调节器疗法正在改变CF护理.

研究的目的:

在调节器治疗之前,在患有CF (CwCF) 的儿童中识别早期肠道微生物特征.
为了将这些前调节器微生物模式与后来的儿童体重状况联系起来.
了解CwCF在调节器治疗中的微生物组在生长中的作用.

主要方法:

从CwCF (13天到60个月) 进行纵向便样本采集.
超基因组测序用于分析微生物种群的丰富性.
多变量回归将微生物组数据与生长指标 (正常体重与超重风险) 联系起来.

主要成果:

在正常体重CwCF和那些有超重风险的人之间,发现了早期微生物组合的显著差异.
早期的微生物组模式比调节器疗法使用更强烈地预测了生长状态.
像*Eggerthella lentha*,*Ruminococcus*和*Bacteroides*这样的特定种类在那些有超重风险的人群中不那么丰富,而*Bacteroides stercoris*则更丰富.

结论:

早期的肠道微生物组是接受调制剂治疗的CwCF生长的强有力的预测因素.
已识别的微生物组特征可以表明超重的风险较高.
研究结果表明,有可能针对微生物组进行干预或提供营养指导,以防止CwCF的并发症.

Cystic Fibrosis: Pathogenesis

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Cystic Fibrosis: Management

Cystic Fibrosis: Management

Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.
Sinus disease and chronic...
