Associations between Gut Microbiota Dysbiosis and Other Risk Factors in Women with a History of Urinary Tract Infections.

(1) Background: Urinary tract infections (UTIs) are among otherwise healthy women represent a problem that requires additional understanding and approaches. Evidencing the link between dysbiosis and UTIs and the associated potential risk factors could lead to therapeutic approaches with increased efficiency under the conditions of reducing the risks associated with antibiotic treatments. The purpose of this study was to evaluate dysbiosis and other potential risk factors in women with a history of urinary tract infections; (2) Methods: Fecal dysbiosis tests were performed comparatively in two groups of women. The first group in-cluded women with recurrent urinary tract infections (rUTI) who had either two or more symp-tomatic episodes of UTI in the previous six months. The second group included women with spo-radic UTIs who did not have >1 UTI during a 12-month period and who did not have another UTI in the last 12 months; (3) Results: An association was shown between intestinal dysbiosis and recurrences of urinary tract infections. Increased body weight was associated with intestinal dysbiosis. Also, the lack of knowledge regarding the risk of using antibiotics and the benefits of probiotics was associated with both dysbiosis and recurrences of urinary tract infections; (4) Conclusions: Dysbiosis can have an impact on the recurrence of urinary tract infections. The risk factors for rUTI and dysbiosis in the sphere of lifestyle are potentially controllable, broadening the perspective for new approaches and changing the paradigm in the treatment of urinary tract infections.

Exploring the Relationship between Lipid Profile, Inflammatory State and 25-OH Vitamin D Serum Levels in Hospitalized Patients.

Anomalies in lipid metabolism involve multifactorial pathogenesis, among other factors, being associated with an inflammatory state and disturbances in vitamin D status. The literature has focused on the binary relationships between inflammation and dyslipidemia, vitamin D and dyslipidemia, or vitamin D and inflammation. Our study aimed to explore the link between all these three factors: 25-OH vitamin D serum levels, the presence of inflammation assessed through serum C-reactive protein (CRP), and serum lipid profile in 2747 hospitalized patients. Our results showed a positive correlation of HDL-C with 25 (OH) vitamin D and a negative correlation of HDL-C with CRP. This relationship had different patterns in the statistical network analysis. The network analysis patterns are preserved for males and females, except for the relationship between CRP and vitamin D, which is present in male cases and absent in females. The same triangular relationship between all three-CRP, vitamin D, and HDL-C was found with different strengths of partial correlation in obese and non-obese patients. This pattern was similar in patients with and without fatty liver. A shifted pattern was found in the network analysis of hypertensive patients. The CRP was negatively correlated with vitamin D and HDL-C, and vitamin D was positively correlated with HDL-C in non-hypertensive patients. Castelli's Risk indexes I and II were positively associated with CRP, suggesting that increased cardiovascular risk is proportional to an inflammatory state. The triad formed by altered serum lipid levels, inflammation, and vitamin D represents a complex relationship marked by specific dynamics between lipidic fractions such as HDL-C and C-reactive protein and vitamin D.
