- Restless legs syndrome in patients on hemodialysis: Polysomnography findings(2019) BAMBINI, Beatriz B. M.; MOYSES, Rosa M. A.; BATISTA, Luci C. D.; COELHO, Brunelle B. S. S.; TUFIK, Sergio; ELIAS, Rosilene M.; COELHO, Fernando M.Introduction: Restless legs syndrome (RLS) is a highly prevalent sleep movement disorder usually accompanied by periodic limb movements of sleep (PLMS). The incidence of RLS and PLMS in patients with end-stage renal disease (ESRD) on dialysis is much higher. Clinically, RLS and PLMS can co-occur. We hypothesized that patients with ESRD on dialysis would have a distinct presentation of RLS, with a higher prevalence of PLMS. Methods: We examined clinical, demographic, biochemical, and polysomnographic characteristics of RLS in patients on dialysis matched to control subjects with normal renal function based on age, sex, body mass index, and frequency of apneas and hypopneas per hour of sleep, defined by the apnea and hypopnea index (AHI), in a proportion of 3:1. Patients with ESRD were on hemodialysis three times per week. Polysomnography was performed overnight in the sleep laboratory. Findings: Patients on dialysis compared to control subjects had a lower amount of N3 sleep (77.6 +/- 39.9 minutes vs. 94.8 +/- 33.7 minutes, p = 0.037) and REM sleep (55.6 +/- 27.5 minutes vs. 74.1 +/- 28.4 minutes, p = 0.006), regardless of the presence of RLS. Among the patients on dialysis, those with RLS had higher PLMS. In the control group, patients with RLS had a lower ferritin level, which was not observed in the dialysis group. There was a significant interaction between PLMS and ESRD (p = 0.001), with a higher prevalence of PLMS in patients with ESRD on dialysis in a model adjusted for AHI, sex, arousals, and age. Factors that were associated with PLMS were RLS (p = 0.003), ESRD (p = 0.0001), and AHI (p = 0.041), with an adjusted R-2 of 0.321. Conclusion: RLS in patients with ESRD on dialysis is independently associated with PLMS, regardless of the severity of sleep apnea, arousals, and age.
- Predialysis serum phosphate levels according to hemodialysis shift: Circadian rhythm matters(2021) DARIO, Ketili Alice; DALBONI, Maria Aparecida; SILVA, Bruno C. da; MARTINS, Carolina Steller Wagner; ARAUJO, Luiza Karla R. P. de; ELIAS, Rosilene M.; MOYSES, Rosa M. A.
- Parathyroidectomized patients have impaired capacity of peripheral vascular constriction during hemodialysis(2016) SILVA, Bruno C.; MOYSES, Rosa M. A.; SILVA, Vitor B.; FREITAS, Geraldo R. R.; ELIAS, Rosilene M.Parathyroidectomy (PTx) seems to improve cardiovascular outcomes and reduce blood pressure levels. However, the effect of PTx on hemodynamic changes during hemodialysis (HD) is still overlooked. This was a prospective cohort design. Patients with end-stage renal disease on maintenance HD were included. Diabetes and nonsinusal rhythm were exclusion criteria. History of PTx was recorded. Finometer monitor was used to access parameters immediately pre- and post-HD sessions. Cardiac index (CI) variation (CI) and peripheral arterial resistance variation (PAR) were the variables of interest. Biochemical and echocardiographic data were also obtained. PTx patients (n=11) were matched to non-PTx patients (n=20). PAR was lower in PTx group in comparison with non-PTx group (P=0.039), which was independent of parathyroid hormone (PTH) levels. Multiple regression analysis showed that PTx, CI, and dialysate calcium remained independently associated with PAR variation and even adjusted for ultrafiltration rate (adjusted r(2)=0.64). In conclusion, parathyroidectomized patients have impaired capacity of vasoconstriction in response to ultrafiltration, an effect independent of serum PTH levels. Further studies are needed to elucidate mechanisms explaining the interaction between PTx and systemic vascular tonus.
- Reprocessing high-flux polysulfone dialyzers does not negatively impact solute removal in short-daily online hemodiafiltration(2014) MELO, Natalia C. V.; MOYSES, Rosa M. A.; ELIAS, Rosilene M.; CASTRO, Manuel C. M.There are no studies evaluating the impact of dialyzer reprocessing on solute removal in short-daily online hemodiafiltration (OL-HDF). Our aim was to evaluate the impact of dialyzer reuse on solute removal in daily OL-HDF and compare with that in high-flux short-daily hemodialysis (SDH). Fourteen patients undergoing a SDH program were included. Pre-dialysis and post-dialysis blood samples and effluent dialysate were collected in the 1st, 7th, and 13th dialyzer uses in SDH sessions and in daily OL-HDF sessions. Directly quantified small solute (urea, phosphorus, creatinine, and uric acid) total mass removal (TMDQ) and clearance (K-DQ) were similar when the 1st, 7th, and 13th dialyzer SDH uses were compared with the 1st, 7th, and 13th daily OL-HDF uses. TMDQ and K-DQ of small solutes were similar among analyzed dialyzer uses in SDH sessions and in daily OL-HDF sessions. beta(2)-Microglobulin TMDQ and K-DQ were statistically higher in daily OL-HDF dialyzer uses than in the respective SDH uses. There was no difference in beta(2)-microglobulin TMDQ and K-DQ among dialyzer uses in daily OL-HDF sessions or in SDH sessions. In daily OL-HDF, albumin loss was significantly different among dialyzer uses (P < 0.001), being lower in the 7th and 13th dialyzer uses than in the first use. Dialyzer reprocessing did not impair solute extraction in daily OL-HDF. beta(2)-Microglobulin removal was greater in daily OL-HDF than in SDH sessions, without significant differences in other solutes extraction. There was a significant reduction in intradialytic albumin loss with dialyzer reprocessing in daily OL-HDF sessions.

- A dangerous entanglement(2011) ELIAS, Rosilene M.; PEDREIRA, Alexandre B.; MACEDO, Etienne; CHAN, Christopher T.Entrapment of guidewires by inferior vena cava filters can occur during the blind insertion of a jugular or a subclavian central venous catheter. Recently, few case reports have been published in the radiology literature. In addition, others have described endovascular techniques aimed at removing entrapped guidewires, avoiding the possibility of vena cava rupture. Given that a temporary hemodialysis venous catheter is frequently used as a first access, the possibility of entrapping the dialysis catheter guidewire should not be neglected.
