ABSTRACT
Urinary tract infections affect more than 50% of women. 25% derive from recurrent UTI (RUTI). It is not known the relationship between obstetric history and RUTI occurrence. Investigate the relationship between obstetric events and RUTI. Multicenter observational retrospective study. Groups: G.RUTI (n = 294): women with RUTI; G.NON.RUTI (n = 126): women without RUTI (treated and cured of renal cancer). Descriptive statistics, ANOVA analysis of variance (with Scheffe's test for normal samples and Kruskal-Wallis for other distributions), Fisher's exact test, Pearson and Spearman correlation studies, and multivariate analysis multiple regression were used. Mean age 61.04 years (19-92), G.RUTI: 56.77 years SD 4.46 (19-85). G.NON.RUTI: 71 years SD 6.73 (25-92) (p = 0.0001). Obstetric history: Nulliparous G.RUTI: 20 (3.4%) G.NON.RUTI: 90 (71.42%) p 0.0001; Eutocic G.RUTI: 416 (70.74%) G.NON.RUTI: 30 (23.8%) p 0.0001. Dystocic G.RUTI: 58 (9.86%) G.NON.RUTI: 56 (44.44%) p 0.0001. G.RUTI abortion: 102 (17.34%) G.NON.RUTI: 30 (23.8%) p 0.1381. Hysterectomy without adnexectomy G.RUTI: 100 (17%) G.NON.RUTI: 18 (14.28%) p 0.5640. Hysterectomy with adnexectomy G.RUTI: 100 (17%) G.NON.RUTI: 66 (52.28%) p 0.0001. Nulliparity, dystocic delivery, and hysterectomy with adnexectomy are more frequent in women without RUTI, while eutocic births are more associated with RUTI. The most prevalent gynaecological-obstetric history in women with RUTI is eutocic delivery associated with a good health state.

BACKGROUND: Fever-7 is a test evaluating host mRNA expression levels of IFI27, JUP, LAX, HK3, TNIP1, GPAA1 and CTSB in blood able to detect viral infections. This test has been validated mostly in hospital settings. Here we have evaluated Fever-7 to identify the presence of respiratory viral infections in a Community Health Center. METHODS: A prospective study was conducted in the "Servicio de Urgencias de Atención Primaria" in Salamanca, Spain. Patients with clinical signs of respiratory infection and at least one point in the National Early Warning Score were recruited. Fever-7 mRNAs were profiled on a Nanostring nCounter® SPRINT instrument from blood collected upon patient enrolment. Viral diagnosis was performed on nasopharyngeal aspirates (NPAs) using the Biofire-RP2 panel. RESULTS: A respiratory virus was detected in the NPAs of 66 of the 100 patients enrolled. Median National Early Warning Score was 7 in the group with no virus detected and 6.5 in the group with a respiratory viral infection (P > .05). The Fever-7 score yielded an overall AUC of 0.81 to predict a positive viral syndromic test. The optimal operating point for the Fever-7 score yielded a sensitivity of 82% with a specificity of 71%. Multivariate analysis showed that Fever-7 was a robust marker of viral infection independently of age, sex, major comorbidities and disease severity at presentation (OR [CI95%], 3.73 [2.14-6.51], P < .001). CONCLUSIONS: Fever-7 is a promising host immune mRNA signature for the early identification of a respiratory viral infection in the community.
