Background And Objectives:
Restless legs syndrome (RLS) is common but often underdiagnosed in patients with end-stage renal disease (ESRD) undergoing hemodialysis, significantly impacting their quality of life. This study investigates the prevalence, risk factors, and psychosocial effects of RLS in this population.
Methods:
A cross-sectional study was conducted among 308 hemodialysis patients at a tertiary care hospital. RLS was diagnosed based on the International Restless Legs Syndrome Study Group criteria. The severity of RLS, sleep quality, and mental health were assessed using the International Restless Legs Syndrome (IRLS) Severity Score, Pittsburgh Sleep Quality Index, and Hospital Anxiety and Depression Scale. Clinical and biochemical parameters were also analyzed. Statistical significance was determined using Chi-squared and unpaired t -tests ( P < 0.05).
Results:
RLS was identified in 46 patients (14.9%). Among them, 56.6% had mild symptoms, 41.3% had moderate symptoms, and 2.1% had severe symptoms. Patients with RLS were younger (50.15 ± 12.19 vs. 57.41 ± 13.43 years, P = 0.001) and had lower body weight (57.89 ± 9.64 vs. 62.78 ± 10.58 kg, P = 0.03). Anxiety and depression were significantly higher in the RLS group ( P = 0.001). Poor sleep quality was reported in 97.8% of RLS patients ( P = 0.001). Hemoglobin ( P = 0.02) and thyroid-stimulating hormone ( P = 0.03) levels also differed significantly between groups.
Conclusions:
RLS is highly prevalent in ESRD patients undergoing hemodialysis and is associated with significant psychosocial burden and poor sleep quality.

One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

01:11Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
