“…The change in each index needs to be examined before HD, when the water is most excessive, and after HD, which reflects the patient’s dry weight status, but these indices have not yet been precisely investigated to date. Chua et al [1] argued that nutritional assessments using lean body mass and BCM measurements were significantly confounded by hydration status, and fat mass was found to be relatively constant using whole-body BIA in a small number of HD subjects. This result is also consistent with our analysis.…”

“…Dry weight estimation and nutrition assessment are vital procedures for hemodialysis (HD) patients because they affect the patient’s prognosis and quality of life. Recently, bioimpedance analysis (BIA) has been widely used to analyze the volume, body composition, and nutritional status of dialysis patients [1–3]. BIA estimates body composition, including intracellular water (ICW), extracellular water (ECW), total body water (TBW), protein mass, mineral mass, skeletal muscle mass, and visceral fat area, based on measurements of impedance, reactance, and phase angle [4].…”

BackgroundThis study compared nutritional parameters in hemodialysis (HD) subjects and controls using bioimpedance analysis (BIA) and investigated how BIA components changed before and after HD.MethodsThis cross-sectional study included 147 subjects on maintenance HD from two hospitals and 298 propensity score-matched controls from one healthcare center. BIA was performed pre- and post-HD at mid-week dialysis sessions.ResultsExtracellular water/total body water (ECW/TBW) and waist-hip ratio were higher in the HD patients; the other variables were higher in the control group. The cardiothoracic ratio correlated best with overhydration (r = 0.425, P < 0.01) in HD subjects. Blood pressure, hemoglobin, creatinine, and uric acid positively correlated with the lean tissue index in controls; however, most of these nutritional markers did not show significant correlations in HD subjects. Normal hydrated weight was predicted to be higher in the pre-HD than post-HD measurements. Predicted ultrafiltration (UF) volume difference based on pre- and post-HD ECW/TBW and measured UF volume difference showed a close correlation (r2 = 0.924, P < 0.01). Remarkably, the leg phase angle increased in the post-HD period.ConclusionThe estimated normal hydrated weight using ECW/TBW can be a good marker for determining dry weight. HD subjects had higher ECW/TBW but most nutritional indices were inferior to those of controls. It was possible to predict UF volume differences using BIA, but the post-HD increase in leg phase angle, a nutritional marker, must be interpreted with caution.

“…24 Patients are typically more hydrated at the start of the dialysis week, after the longer interdialytic interval, compared with later in the week. The ranges of agreement between measurements of body composition with the changes in ICW and ECW were too wide to allow for simple pre-to post-haemodialysis adjustments in clinical practice.…”

RESUMO Objetivo: avaliar o benefício de paratireoidectomia em pacientes submetidos à hemodiálise, em relação ao estado nutricional e bioquímico, composição corporal e a qualidade de vida. Métodos: estudo longitudinal envolvendo 28 adultos em programa de hemodiálise, com hiperparatireoidismo secundário grave, avaliados antes e um ano após a cirurgia. Critérios de inclusão: níveis de paratormônio dez vezes superior ao valor de referencia e doença renal crônica em programa de hemodiálise. O índice de massa corporal foi utilizado para classificação do estado nutricional. A bioimpedância elétrica para avaliação da composição corporal. A análise bioquímica incluiu dosagem de lipídios e marcadores do metabolismo ósseo. A qualidade de vida foi avaliada pelo questionário SF36 (Short Form Health Survey). Todos os pacientes foram submetidos à paratireoidectomia total com implante em antebraço. Resultados: houve ganho significativo de peso corporal (61,7 vs 66,0 kg; p<0,001), da massa celular corporal (22,0 vs 24,5 kg/m2; p=0,05) e da qualidade de vida (p=0,001) após a cirurgia. Com relação ao metabolismo ósseo, PTH intacto, cálcio, fósforo e fosfatase alcalina, se estabilizaram e houve melhora em parâmetros bioquímicos, tais como albumina e hemoglobina. Conclusão: a paratireoidectomia melhora a sobrevida em pacientes de hemodiálise e está associada a aumento de peso, ganho de massa óssea e melhoria na qualidade de vida.
