Could Nocturia Be an Indicator of an Undiagnosed Sleep Disorder in Male Veterans?

[Evolution of the USP and IPSS score after continuous positive airway pressure sleep apnea therapy at night]

INTRODUCTION

To assess the impact of nocturnal continuous positive airway pressure (CPAP) treatment of obstructive sleep apnea (OSA) on lower urinary tract (LUTS) symptoms.

MATERIALS AND METHODS

A prospective, monocentric study was conducted between June 2018 and August 2019. Patients with moderate to severe OSA with an indication for treatment with nocturnal CPAP in combination with SBAU were included. SBAUs and their impact were evaluated by completing two self-administered questionnaires (Urinary Symptom Profile (USP) and International Prostate Score Symptom (IPSS)) filled out during the night-time ventilatory polygraph or diagnostic polysomnography for OSA and after 4 months of CPAP treatment.

RESULTS

In 79 patients, after four months of CPAP treatment, USP scores for stress urinary incontinence and overactive bladder were significantly improved, respectively 0.65±1.38 vs 1.13±2.10 ; p<0.0001 and 3.24±2.58 vs 5.43±3.66 ; p<0.0001, IPSS and IPSS-Qdv were significantly improved, respectively 5.20±3.78 vs. 7.44±5.05 ; p<0.0001 and 1.93±1.26 vs. 2.27±1.56 ; p=0.002 as well as IPSS score items on pollakiuria, urgency and nocturia.

CONCLUSION

Treatment with CPAP significantly improved SBAU in four months. Testing urology patients for symptoms of OSA in urology patients seeking SBAU would allow referral of patients suspected of OSA to a specialist for diagnosis and management if necessary.

Shift Workers With Shift Work Disorder Have Worse Lower Urinary Tract Symptoms

OBJECTIVE

To examine the association between shift work or shift work disorder (SWD) and lower urinary tract symptoms (LUTS). Nonstandard shift workers are defined as those working shifts outside of a normal 7 AM-6 PM work day.

METHODS

Men presenting to a single andrology clinic between July 2014 and June 2017 completed questionnaires that included questions about work schedules, shift work status, SWD[1][1], personal well-being via the Patient Health Questionnaire-9, and LUTS (International Prostate Symptom Score [IPSS]). Men who had previously undergone prostate surgery were excluded. Shift work and SWD on IPSS was assessed via multivariate linear regression.

RESULTS

Of the 2571 men who completed all questionnaires, 619 (24.1%) reported working nonstandard shifts in the past month. Of these, 196 (31.7%) had high risk of SWD as determined by a questionnaire. When controlling for age, medications, surgical intervention for benign prostatic hyperplasia, comorbidities, and testosterone (T) levels, nonstandard shift work overall was not associated with worse LUTS (P = .82). However, nonstandard shift workers at high risk for SWD had IPSS scores that were clinically significantly higher (3.74 points ± 0.57 standard error) than nonstandard shift workers without SWD (P <.0001).

CONCLUSION

Nonstandard shift workers at high risk for SWD have worse LUTS than those without SWD. However, no association between nonstandard shift work and LUTS was found.

Awareness of obstructive sleep apnea-hypopnea syndrome among the general population of the Lorraine Region of France

OBJECTIVE

Obstructive sleep apnea-hypopnea syndrome (OSAHS) seems to be underdiagnosed. The aim of this study was to assess awareness of OSAHS among the general population of the Lorraine Region of France.

METHODS

A descriptive epidemiological study was carried out from July to November 2015 in the Lorraine Region, using an anonymous questionnaire that assessed knowledge of OSAHS-related symptoms and complications. The survey was also circulated on the Internet via social media. Exclusion criteria comprised age under 18 years, refusal to fill out the questionnaire and linguistic barrier.

RESULTS

1307 subjects filled out the survey: 1020 on paper format and 287 via the Internet. About two-thirds of the population recognized a majority of symptoms. However, there was a significant lack of knowledge of complications, especially cardiological and neurological. Suffering from OSAHS, having had higher education, and being under 40 years of age, were factors linked to better awareness of the syndrome. Internet respondents also showed better awareness.

CONCLUSION

Despite encouraging results regarding OSAHS symptoms, the general population showed limited awareness of its complications. Innovative educational campaigns must be organized to inform practitioners and the general public about the disease and raise awareness of its complications.

Impaired Sleep Quality is Associated With More Significant Lower Urinary Tract Symptoms in Male Shift Workers

OBJECTIVE

To determine the association between sleep quality and severity of lower urinary tract symptoms (LUTS) in men working nonstandard shifts, a population at risk of poor sleep quality.

METHODS

Men who presented to a single andrology clinic between July and October 2014 and worked nonstandard shifts completed the International Prostate Symptom Score (IPSS) and responded to questions regarding their work habits, sleep quality, and physical or cognitive function. We assessed the relationship between age, sleep quality, physical or cognitive function, and severity of LUTS.

RESULTS

A total of 228 men with a mean ± standard deviation age of 41.8 ± 5.7 (range 21-76) years reported working nonstandard shifts, with the majority working these shifts for more than 1 year (81%). Men with difficulties falling asleep reported more severe LUTS than men who did not have difficulty falling asleep (IPSS score 9 vs 6, P <.001). Men who reported difficulty staying asleep or falling back asleep after awakening also reported more severe LUTS (IPSS scores 6 vs 13, P = .004; 5 vs 13, P <.001, respectively). Men with a decreased sense of well-being or decreased physical or cognitive function also reported more severe LUTS (IPSS score 6 vs 9, P <.0010; 6 vs 10, P = .016, respectively). All findings were independent of subject age.

CONCLUSION

Men working nonstandard shifts who have difficulty falling asleep, staying asleep, and falling back asleep report more severe LUTS than men without similar sleep difficulties. Men with a decreased sense of well-being or decreased physical or cognitive function also report worse LUTS. These findings implicate sleep quality as a possible risk factor for LUTS symptom severity.
