Purpose: To determine the risk factors predicting upper urinary tract (UUT) damage using a grading system for upper urinary tract dilation (UUTD) and a descriptive system for all urinary tract dysfunction (AUTD) in patients with myelodysplasia. Methods: Six hundred thirty-seven patients with myelodysplasia were evaluated at our center from January 2008 to November 2019. Clinical data, ultrasonography, magnetic resonance urography, and video-urodynamics (VUDS) parameters were collected. Univariate and multivariate analyses were used to determine the risk factors predicting UUT damage. Results: Three hundred eighty-three males and 254 females were included. The average course of lower urinary tract symptoms (LUTS) was 14.08±7.07 years (range, 3–31 years). The urodynamic diagnoses of all patients were as follows: detrusor overactivity, 26.8%; detrusor underactivity, 6.44%; and acontractile detrusor, 66.72%. UUT damage was determined in 66.56% of the patients. Of the patients, 28.73 % had vesicoureteral reflux (VUR) during filling (bilateral, n=50; unilateral, n=133) on fluoroscopy during VUDS testing. Two hundred thirty-four patients had UUTD (bilateral, n=203; unilateral, n=31). The occurrence of hydronephrosis based on ultrasonography was closely related to ipsilateral VUR (P<0.05). Absent of bladder sensation, long-term course of LUTS, decreased maximum cystometric capacity (MCC) and bladder compliance (BC), and increased postvoid residual urine (PVR) were shown to be independent risk factors in logistic regression analysis. Conclusions: This retrospective study using UUTD and AUTD systems indicated that patients with myelodysplasia have a high incidence of UUT damage. Absence of bladder sensation, long-term course of LUTS, decreased MCC and BC, and increased PVR were independent risk factors predicting UUT damage.

Mycobacterium vaccae induces a strong Th1 response that subsequently declines in C57BL/6 mice

Mycobacterium (M.) vaccae is a fast-growing species of saprophytic bacteria that is widely distributed. To understand the host immuneresponses induced by M. vaccae isolated from bovine submaxillary lymph nodes, C57BL/6 mice were infected with reference strain M. bovisBacillus Calmette-Guérin (BCG) and isolated M. vaccae using intraperitoneal injections. Comparison of the bacterial replication and organpathology between M. vaccae and M. bovis BCG revealed that M. vaccae was more malignant than M. bovis in mice. We also demonstratedthat serum from the M. vaccae-infected mice contained a higher expression level of gamma-interferon (IFN-), tumor necrosis factor alpha,monocyte chemoattractant protein-1, interleukin (IL)-4, IL-12, IL-10 and transforming growth factor beta than did the other groups, especiallyafter week 4. Furthermore, when the numbers of CD3+CD4+IFN-+ and CD3+CD4+IL4+ cells in the infected mice were observed by flowcytometry, we found that a powerful T helper 1 (Th1) response was induced by M. vaccae infection, which was associated with the emergenceof CD3+CD4+IFN-+ cells. However, the Th1 response declined over time, which was associated with appearance of the CD4+CD25+FoxP3+and CD4+CD25+CD152+Treg cell reaction. In addition, a strong Th2 response was found. Finally, we found that M. vaccae infection increasedthe production of type I IFNs, which was associated with a reduced Th1 response.
