We evaluated the use of telemedicine in the long-term control of stable patients undergoing peritoneal dialysis at home. From September 2003 to August 2005, patients were randomly selected from current cases and invited to join study group A, in which they had telemedicine support. Patients not selected for this group, or who refused the invitation, were placed in study group B, and used for comparison. There were 25 patients in group A and 32 patients in group B. Videoconferencing equipment was installed in each patient's home, connected to a videoconferencing unit at the hospital by three ISDN lines. Patients in group A were followed for a mean of 8 months (range 3-24) with alternate months of teleconsultations and hospital visits. A total of 172 teleconsultations were conducted. A mean of 22 min (SD 9) were spent on each teleconsultation, significantly less than in hospital consultations, which took a mean of 33 min (SD 8) (P<0.01). In 148 teleconsultations (89%) medical treatment was modified. In 4 cases (2%) patients needed a hospital visit. In all instances (100%) the condition of the catheter exit site and the presence of oedema could be evaluated. In group A, the estimated cost of telemedicine was euro198 and that of a hospital visit was euro177. The mean hospitalization rate was 2.2 days/patient/year in group A and 5.7 days/patient/year in group B (P<0.05). Home telemedicine appears to be clinically useful in the long-term follow-up of stable patients undergoing peritoneal dialysis, and the costs and savings also seem to be encouraging.
Background and objectivesC3 glomerulopathy is a complement-mediated disease arising from abnormalities in complement genes and/or antibodies against complement components. Previous studies showed that treatment with corticosteroids plus mycophenolate mofetil (MMF) was associated with improved outcomes, although the genetic profile of these patients was not systematically analyzed. This study aims to analyze the main determinants of disease progression and response to this therapeutic regimen.Design, setting, participants, & measurements We conducted a retrospective, multicenter, observational cohort study in 35 nephrology departments belonging to the Spanish Group for the Study of Glomerular Diseases. Patients diagnosed with C3 glomerulopathy (n=81) or dense deposit disease (n=16) between January 1995 and March 2018 were enrolled. Multivariable and propensity score matching analyses were used to evaluate the association of clinical and genetic factors with response to treatment with corticosteroids and MMF as measured by proportion of patients with disease remission and kidney survival (status free of kidney failure).ResultsThe study group comprised 97 patients (84% C3 glomerulopathy, 16% dense deposit disease). Forty-two patients were treated with corticosteroids plus MMF, and this treatment was associated with a higher rate of remission and lower probability of kidney failure (79% and 14%, respectively) compared with patients treated with other immunosuppressives (24% and 59%, respectively), or ecluzimab (33% and 67%, respectively), or conservative management (18% and 65%, respectively). The therapeutic superiority of corticosteroids plus MMF was observed both in patients with complement abnormalities and with autoantibodies. However, patients with pathogenic variants in complement genes only achieved partial remission, whereas complete remissions were common among patients with autoantibody-mediated forms. The main determinant of no remission was baseline proteinuria. Relapses occurred after treatment discontinuation in 33% of the patients who had achieved remission with corticosteroids plus MMF, and a longer treatment length of MMF was associated with a lower risk of relapse.ConclusionsThe beneficial response to corticosteroids plus MMF treatment in C3 glomerulopathy appears independent of the pathogenic drivers analyzed in this study.
Normotensive hyperthyroid patients exhibit higher ambulatory SBP throughout 24 h than normotensive euthyroid subjects. Control of hyperthyroidism decreases ambulatory SBP values. Mean nocturnal fall in BP is comparable in normotensive hyperthyroid patients and control subjects.
In patients older than 75 years with advanced chronic kidney disease (CKD), the decision between treatment with dialysis [intention to treat with dialysis (ITD)] or conservative care (CC) is a challenge. Geriatric assessment can be helpful. The aim was to identify which factors had had an influence on decision-making. Methods: We recruited 56 patients. At baseline we analyzed age, frailty (defined following the criteria of Fried et al. [J Gerontol A Biol Sci Med Sci 2001;56:146-156]), dependence for activities of daily living (ADL), cognitive impairment, depression, comorbidity, cardiovascular disease, and diabetes. After full information about prognosis and treatment options, the preferences of the patients and families were taken into consideration as determinants in the decision-making process. During the follow-up, we evaluated clinical and laboratory parameters, hospitalization, mortality and reevaluated frailty. Results: Twenty patients opted for CC, and 36 patients opted for ITD. On univariate analysis, the predictive factors of the election of CC were age, prefrailty, cognitive impairment, and dependence for ADL. In the multivariate analysis, age and prefrailty remained as predictors for the choice of CC. Hospitalizations were more frequent in CC. Survival was similar in both groups (p = 0.098). Conclusions: Frailty assessment could be useful for decision-making about the treatment in elderly patients with CKD. CC may be a good treatment option.
