The prevalence of sleep disorders is higher in patients with kidney failure than the general population. We studied the prevalence of sleep disorders in 88 (mean age; 41.59 ± 16.3 years) chronic hemodialysis (HD) patients at the Urology and Nephrology Center, Mansoura Uni­versity, Egypt over 4-month period. The investigated sleep disorders included insomnia, restless leg syndrome (RLS), obstructive sleep apnea syndrome (OSAS), excessive daytime sleepiness (EDS), narcolepsy and sleep walking, and we used a questionnaire in accordance with those of the International Restless Legs Syndrome Study Group, the Berlin questionnaire, Italian version of Epworth Sleepiness Scale, International Classification of Sleep Disorders, and the specific ques­tions of Hatoum's sleep questionnaire. The prevalence of sleep disorders was 79.5% in our pa­tients, and the most common sleep abnormality was insomnia (65.9%), followed by RLS (42%), OSAS (31.8%), snoring (27.3%), EDS (27.3%), narcolepsy (15.9%), and sleep walking (3.4%). Insomnia correlated with anemia (r=0.31, P= 0.003), anxiety (r=0.279, P= 0.042), depression (r=0.298, P= 0.24) and RLS (r=0.327, P= 0.002). Also, RLS correlated with hypoalbuminemia (r=0.41, P= < 0.0001), anemia (r=0.301 and P= 0.046), hyperphosphatemia (r=0.343 and P= 0.001). EDS correlated with OSAS (r=0.5, P= < 0.0001), snoring (r=0.341, P= 0.001), and social worry (r=0.27, P= 0.011). Sleep disorders are quite common in the HD patients, especially those who are anemic and hypoalbuminemic. Assessment of sleep quality, preferably with polysomno­graphy, is necessary to confirm our results. Interventional studies for management of sleep disor­ders in HD patients are warranted.

   Introduction Top

Sleep disorders affect the majority of chronic kidney disease (CKD) patients. [1] Some investi­gators hypothesized that end-stage renal disease (ESRD) directly influences the quality of sleep. [2] Interestingly, 80% of hemodialysis or perito­neal dialysis patients suffer from sleep abnor­malities, [3] and the prevalence is higher than that in the general population. The most frequently reported complaints are insomnia, restless leg syndrome (RLS), sleep-disordered breathing and excessive daytime sleepiness (EDS). [5]

The causal link between conventional dialy­sis and sleep dissatisfaction remains specula­tive, [6] while psychological causes such as an­xiety and depression, [7],[8] and physical disturban­ces such as hypertension, muscle cramps, and electrolytes or body fluids imbalances may sig­nificantly contribute to the sleep disorders. [5] In addition, primary sleep disorders such as rest­less legs syndrome (RLS) and sleep-disordered breathing (SDB) are potential contributors. [9]

Recently, Parker et al proposed different etio­logies for sleep problems in CKD and chronic HD patients. Functional and psychological fac­tors may play a more prominent role in the former group, while intrinsic sleep disruption may play a more significant role in the latter. [10] Furthermore; there is race influence on the self-reported sleep quality. [11]

We aimed in this study to evaluate the self­reported sleep quality in our hemodialysis po­pulation in order to estimate the prevalence of sleep disorders and determine the factors affec­ting them in this patient population.

   Patients and Methods Top

We studied 88 chronic HD patients in a cross­sectional design, who attended the 3 hemodia­lysis units of the Urology and Nephrology Cen­ter, Mansoura University, Egypt, over 4 months period. The patients were randomly selected for the study, and randomization was done ma­nually, without the use of a computer algo­rithm, to allocate every other patient on the patients' list. The inclusion criteria included a­dult patients > 18 years, who consented to par­ticipate in the study and were maintained on conventional hemodialysis (CHD) three times per week for at least 6 months. The patients were relatively young (mean age: 41.59 ± 16.3 years) with a male predominance (68.2%).

With the use of a questionnaire-based survey, we examined the prevalence of symptoms that reflect sleep disorders such as insomnia, RLS, OSAS, EDS, narcolepsy, and sleepwalking in our study patients. In order to determine the prevalence of sleep disturbances and the po­ssible effect of demographic or clinical data on sleep patterns, our questionnaire consisted of two parts. The first part was completed by the nephrologists at the dialysis unit and included: demographic data, some information about pa­tient's lifestyle such as smoking, general medi­cal history and pharmacological therapy. The questions concerned with sleep description were guided by the pulmonologist at the Sleep-Disor­dered Breathing Unit in our university hospital. The following questionnaires were used to de­sign our questionnaire:

  1. The score for insomnia was done accor­ding to the Ohayon method. [12] Those with insomnia but no daytime dysfunction were labeled as having level I, while insomnia and day-time dysfunction was labeled as level 2.
  2. The International Restless Legs Syndrome Study Group (IRLSSG) to evaluate RLS. [13]
  3. The Berlin Questionnaire to evaluate OSAS. [14]
  4. The Italian version of Epworth Sleepiness Scale (ESS) to evaluate EDS as suggested by Vignatelli et al in 2003. A score of > 9 was considered as the minimal criterion for the diagnosis of EDS. [15]
  5. The International Classification of Sleep Disorders (ICSD) to evaluate narcolepsy. [16]
  6. Hatoum's sleep questionnaire to evaluate sleep-walking. [17]
The study was approved by the Local Medi­cal Research and Ethics Committee. Informed consent was obtained from all the participants after being informed in detail of the purpose and methods of the study. The study was con­ducted according to the Good Clinical Practice (GCP) guidelines.

   Statistical Analysis Top

Analysis was performed using the Statistical Package for Social Science (SPSS) version 10. Data are expressed as mean ± standard devia­tion (SD) unless stated otherwise. ANOVA single factor, Student's t and Chi-squared tests were used as deemed appropriate. The relation of investigated sleep disorders with the other baseline characteristics was assessed by using spearman's correlation. Odds ratios were taken as approximation of relative risk and expressed with 95% CI for increased urinary albumin ex­cretion in the study population. P value :5 0.05 was considered statistically significant.

   Results Top

The mean duration of dialysis in our study patients was 54.48 months. Seventeen percent of our patients were smokers. A significant pro­portion of our cohort suffered from some psy­chiatric disorders such as anxiety (43.2%), dep­ression (27.2%) and social worry (30.7%). [Table 1] shows the dialysis-associated parameters for our patients. They were adequately dialyzed (Kt/V > 1.2), but hypoalbuminemic and anemic.

The prevalence of sleep disorders was 79.5% in our patients. The most common sleep ab­normality was insomnia (65.9%), followed by RLS (42%), OSAS (31.8%), snoring (27.3%), EDS (27.3%), narcolepsy (15.9%), and sleep walking (3.4%).

There was comparable parameters in patients without insomnia and those with level 1 and level 2 of insomnia except for sodium plasma levels (P= 0.022). However, RLS patients with low-risk (< 9) and high-risk (> 9) on Epworth questionnaire were not different regarding their electrolytes level as well as their markers of hemodialysis adequacy.

Insomnia correlated with the presence of ane­mia (r=0.31 and P= 0.003), anxiety (r=0.279 and P= 0.042), depression (r=0.298 and P= 0.24), and RLS (r=0.327 and P= 0.002). Also, RLS correlated with the presence of hypoalbu­minemia (r=0.41 and P= < 0.0001), anemia (r= 0.301 and P= 0.046), and hyperphosphatemia (r=0.343 and P= 0.001). EDS correlated with OSAS (r=0.5 and P= < 0.0001), snoring (r= 0.341 and P= 0.001), and social worry (r=0.27 and P= 0.011). We found no significant corre­lation between sleep disorders and gender, cause of renal failure (diabetics vs non diabetics), and smoking habits.

As shown in [Table 2], the risk factors for in­somnia among our study population were inade­quate dialysis, anemia, hypoalbuminemia and RLS. In addition, the risk factors for RLS in­cluded anemia, hypoalbuminemia, and hyper­phosphatemia [Table 3].

   Discussion Top

The results of our study show increased pre-valence of sleep disorders in the HD popula­tion. The sleep disorders are usually observed in the old age groups, [18],[19] while our patients' mean age was relatively young, which supports more the notion that uremia and its compli­cations are more likely the cause of sleep dis­orders observed in HD patients than aging.

The prevalence of sleep disorders observed in our patients was nearly similar to that reported elsewhere [20] with lesser, [21],[22] or higher [23] preva­lence of insomnia. Varied prevalence was also observed regarding RLS [24],[25] and sleep apnea. [26]

The country to country variability has been recently noted, [27] and could be explained at least in part by the suggested racial influence on self-reported sleep quality. [11]

Interestingly, we found no difference between diabetic and non-diabetic HD patients regar­ding the associated psychiatric disorders and the investigated sleep disorders, except more prevalent snoring among diabetics. Unruh and co-workers noted that sleep-disordered brea­thing (SDB) was more common in HD patients with DM. [28]

Anemia was indicative of the most frequently reported sleep abnormalities, insomnia and RLS. Such observation was reported by many inves­ tigators. [2],[21],[23]

Hypoalbuminemia was recently reported to be associated with lower sleep and even life quality. [29] in our study, we found that hypoal­buminemia increased the odds ratio for in­somnia and RLS.

Lower dialysis dose and hyperphosphatemia were highly correlated with sleep disorders in our study. Underdialysis was considered by Chen and colleagues [30] as a factor that increa­sed the likelihood of sleep disruption in hemo­dialysis patients, while Perl and associates [31] regarded the sleep abnormality as a marker of inadequate dialysis. Also, previous studies sho­wed that higher serum phosphate was associa­ted with a lower sleep quality in maintenance dialysis patients. [32]

RLS increased the odds for sleep disorders in our study patients. Such observation is in agreement with that in other populations. [22],[23],[24],[25],[26],[27],[28],[29],[30],[31],[32],[33]

We did not detect any significant correlation between the noticed sleep disruption and age as many other did, [2],[20],[34] possibly because of the relatively young age of our study population. Also, female gender was not a contributing factor for the sleep abnormalities seen in this study as in others. [23],[24],[25],[26],[27],[28],[29],[30],[31],[32],[33],[34] However, this study and many others [22],[23],[29] found a correlation of psy­chological factors such as depression, anxiety, and social worry with the sleep quality impair­ment in chronic HD patients.

We have not noticed any association between cigarette smoking and sleep disorders as many other have observed. [20],[21],[22],[23],[24],[25],[26],[27],[28],[29],[30],[31],[32],[33],[34],[35] A simple explanation would be the small percentage (17%) of our study population who were smokers.

Finally, appropriate management of sleep dis­orders could improve cognitive functions [36] and quality of life. [27],[28],[29],[30],[31],[32],[33],[34],[35],[36],[37] Although sleep disorders are not improved by conventional modes of dialy­sis [38] nocturnal hemodialysis (NHD) has been suggested as a treatment option as it norma­lizes the higher heart rates and impaired vagal and augmented sympathetic hear rate modu­lation during sleep with better removal of ure­mic toxins. [39] Also it increases the pharyngeal cross-sectional area. [40] Furthermore, cool dialy­sate (35 degrees centigrade) during chronic HD was observed to improve nocturnal sleep. [41]

We conclude that Sleep disorders are quite common in the HD patients, especially those who are anemic and hypoalbuminemic. Assess­ment of sleep quality, preferably with polys­omnography, is necessary to confirm our re­sults. Interventional studies for management of sleep disorders in HD patients are warranted.
