Characteristics of urinary microflora in women with type 2 diabetic peripheral neuropathy without lower urinary tract symptoms
Objective
To investigate the characteristics of urinary microflora in women with type 2 diabetic peripheral neuropathy without lower urinary tract symptoms.
Methods
By completing nerve conduction function and the American Urological Association Symptom Index questionnaire (AUA-SI), a total of 30 cases of women hospitalized with type 2 diabetes and no symptoms of lower urinary tract from May 2017 to August 2018 were included. 17 patients with diabetic peripheral neuropathy were assigned to the DPN group, and 13 patients without diabetic peripheral neuropathy were assigned to the nDPN group. Urine specimens were collected from clean catch midstream urine and processed for extracting DNA. Microbial diversity and composition were analyzed using the Illumina sequencing platform targeting to 16S rDNA gene. Sequencing reads were processed by QIIME. LEfSe algorithm was used to analyze the flora with significant differences between the two groups.
Results
The duration of diabetes in the DPN group was lower than that in the nDPN group [(4.12 ± 3.28)years vs.(8.03 ± 6.11)years, P = 0.03], and the retinopathy cases were more in the DPN group than those in the nDPN group (6 vs. 0, P=0.03). Except for above two indicators, there was no significant difference in demographic characteristics between DPN group and nDPN group(P>0.05). The urinary microenvironment of DPN was characterized by increased bacterial richness(sobs index, chao index and aec index, 67.24±40.25 vs.108.69±57.18; 81.36±47.99 vs.122.55±55.70; 88.58±55.03 vs.125.78±53.03, all P 0.05). LEfSe analysis showed that at the genus level, the relative abundance of eight genera(e.g., Bacillus, Duganella, Leptotrichia, Proteus, Propionibacterium, Pseudoxanthomonas, Bdellovibrio and uncultured_soil_bacterium) in DPN group decreased at the level of genus(P<0.05).
Conclusions
Female patients with type 2 diabetes without lower urinary tract symptoms of peripheral neuropathy exhibit a different microbial community compared to nDPN controls. Mycoplasmataceae may be a potential biomarker for patients with DPN.
Key words:
Diabetic peripheral neuropathy; No lower urinary tract symptoms; Urinary microbiome
期刊介绍：
Chinese Journal of Urology (monthly) was founded in 1980. It is a publicly issued academic journal supervised by the China Association for Science and Technology and sponsored by the Chinese Medical Association. It mainly publishes original research papers, reviews and comments in this field. This journal mainly reports on the latest scientific research results and clinical diagnosis and treatment experience in the professional field of urology at home and abroad, as well as basic theoretical research results closely related to clinical practice.
The journal has columns such as treatises, abstracts of treatises, experimental studies, case reports, experience exchanges, reviews, reviews, lectures, etc.
Chinese Journal of Urology has been included in well-known databases such as Peking University Journal (Chinese Journal of Humanities and Social Sciences), CSCD Chinese Science Citation Database Source Journal (including extended version), and also included in American Chemical Abstracts (CA). The journal has been rated as a quality journal by the Association for Science and Technology and as an excellent journal by the Chinese Medical Association.
