Aim: Lower urinary tract symptoms (LUTS) are a common urological referral, which sometimes can have a neurological basis in a patient with no formally diagnosed neurological disease (“occult neurology”). Early identification and specialist input is needed to avoid bad LUTS outcomes, and to initiate suitable neurological management.Methods: The International Continence Society established a neurological working group to consider: Which neurological conditions may include LUTS as an early feature? What diagnostic evaluations should be undertaken in the LUTS clinic? A shortlist of conditions was drawn up by expert consensus and discussed at the annual congress of the International Neurourology Society. A multidisciplinary working group then generated recommendations for identifying clinical features and management.Results: The relevant conditions are multiple sclerosis, multiple system atrophy, normal pressure hydrocephalus, early dementia, Parkinsonian syndromes (including early Parkinson's Disease and Multiple System Atrophy) and spinal cord disorders (including spina bifida occulta with tethered cord, and spinal stenosis). In LUTS clinics, the need is to identify additional atypical features; new onset severe LUTS (excluding infection), unusual aspects (eg, enuresis without chronic retention) or “suspicious” symptoms (eg, numbness, weakness, speech disturbance, gait disturbance, memory loss/cognitive impairment, and autonomic symptoms). Where occult neurology is suspected, healthcare professionals need to undertake early appropriate referral; central nervous system imaging booked from LUTS clinic is not recommended.Conclusions: Occult neurology is an uncommon underlying cause of LUTS, but it is essential to intervene promptly if suspected, and to establish suitable management pathways.

The objective of this paper is to assess overactive bladder (OAB) symptom bother (SB) and health-related quality of life (HRQL) among patients with systemic lupus erythematosus (SLE) and primary Sjögren syndrome (pSS). We recruited adult SLE and pSS patients and two groups of age- and sex-matched controls. We applied the OAB questionnaire-short form (OABq-SF) to all participants to assess SB and HRQL and collected clinical information relevant for OAB. We compared the OABq-SF scores for SB and HRQL between patients and controls using univariate and multivariate linear regression analysis. We recruited 95 rheumatic patients (68 SLE, 27 pSS) and 231 controls. Compared to controls SLE patients showed higher OABq-SF SB scores (22.6 ± 20.4 vs 14.7 ± 17.0, p = 0.004) and lower HRQL scores (89.8 ± 15.8 vs 93.8 ± 11.4, p = 0.044). On multivariate analysis SLE was significantly associated with a higher SB score (ß-coefficient 7.13, p = 0.008) and tended to be associated with worse HRQL values (ß-coefficient –3.53, p = 0.055). Patients with pSS had numerically higher mean SB scores (22.8 ± 22.5 vs 16.2 ± 18.0, respectively, p = 0.107) and lower HRQL scores (91.0 ± 10.7 vs 93.2 ± 11.6, respectively, p = 0.369), although these differences were not statistically significant. Diagnosis of pSS was not significantly associated with SB or HRQL scores on univariate or multivariate analysis. Patients with SLE have significantly worse OAB-SB and poorer HRQL compared to controls. A similar trend was seen for pSS patients, especially for SB. These findings suggest that clinically subtle OAB symptoms may be present in rheumatic patients for whom, later on, bladder pain syndrome may occur.

Background/Objectives: Urinary tract infections (UTI) represent a highly frequent and debilitating disease. Immunoactive prophylaxis, such as the polyvalent bacterial whole-cell-based sublingual vaccine MV140, have been developed to avoid antibiotic use. However, the effectiveness of this tool in the Portuguese population is still unknown. This study aims at assessing the effectiveness of treatment with MV140 in a cohort of Portuguese patients presenting with recurrent UTIs. Methods: Prospective observational real-life study of 125 patients with complicated and uncomplicated recurrent UTIs treated with MV140. The primary outcome was a reduction in frequency and severity of UTIs after a follow-up of 12 months. Overall satisfaction, adverse events, and assessment of the effectiveness of MV140 in subgroups of patients with specific risk factors for UTIs were secondary outcomes. Results: In the 12 months after treatment outset, 38% of patients were UTI-free, 34% reported 1 or 2 UTI episodes, and the remaining 28% presented 3 or more UTIs, corresponding to a mean reduction of 3.20 (2.87–3.53, 95% C.I.; p < 0.001) UTI episodes per year per patient. The effectiveness of MV140 was the same regardless of sex, BMI, regular sexual activity, hypertension, diabetes mellitus, depression, paraplegia, performance of intermittent self-catheterization, indwelling bladder catheter, or previous use of other UTI-preventing vaccines. We observed a higher effectiveness in post-menopausal women compared to pre-menopausal (74.7% vs. 59.4%, respectively, p = 0.029). A total of 73% of patients reported a reduction in symptom severity or days of disease, and the mean global satisfaction was 7.52/10. Conclusions: MV140 demonstrated to be effective in the reduction rate of recurrent UTIs in a cohort of adult Portuguese patients.
