BackgroundChronic kidney disease (CKD) is an important public health problem. Most of the evidence on its costs relates to patients receiving dialysis or kidney transplants, which shows that, in these phases, CKD poses a high burden to payers. Less evidence is available on the costs of the predialytic phase.ObjectiveThe aim of this study was to estimate the annual cost of patients with CKD not receiving dialysis treatment, using the Italian healthcare system perspective and a prospective approach.MethodsA 3-year observational study (December 2010–September 2014) was carried out to collect data on resource consumption for 864 patients with CKD. Costs were estimated for both patients who completed the follow-up and dropouts.ResultsThe mean annual total (healthcare) cost per patient equalled €2723 (95% confidence interval 2463.0–2983.3). Disease severity (higher CKD stage), multiple comorbidities, dropout status and belonging to the southern region are predictive of higher costs. Pharmaceuticals, hospitalisation, and outpatient services account for 71.5, 18.8 and 9.7% of total healthcare expenditure, respectively. Recent estimates of Italian costs of patients receiving dialysis are nine times the unit costs of CKD for patients estimated in this study. Unit costs at stage 5 CKD (the highest level of severity) equals 4.7 times the costs for patients at stage 1 CKD.ConclusionDespite its limitations, this study provides further evidence on the opportunity to invest in the first phases of CKD to avoid progression and an increase in healthcare costs.
Objective. To determine efficacy and safety of Carbopol 974P in the treatment of severe to moderate keratoconjunctivitis sicca (KCS) in patients with primary Sjögren’s syndrome (SS) not responding to standard treatment with artificial tears. Methods. 60 patients (57 F, 3 M, mean age 52.5±12.0, mean disease duration 12.2±7.1 yrs) affected with primary SS diagnosed according to the European Community Study Group criteria were studied. Foregoing medications for SS and artificial tears for KCS have not been changed within 3 and 2 months respectively prior to the study onset. In all cases Carbopol 974P was added because symptoms of KCS were not adequately controlled with traditional lubricants. Schirmer I test, B.U.T. (break up time), rose Bengal-stain, clinical ophthalmological examination (i.e. fluorescein staining, keratis, corneal infiltrates and ulcers) and a questionnaire for dry eye symptoms (range 0-30) were performed at entry (T0) and after 2 (T1) and 12 (T2) weeks. Assessment of global efficacy was obtained by VAS 0-100 at T2 either by patients and by the ophthalmologist. Results. Lachrymal tests significantly improved after 2 and, even more, after 12 weeks. Clinical ophthalmologic picture also ameliorated: a remarkable reduction of fluorescein positive lesions was demonstrated from 71.6% of the cases at T0 to 38.3% at T2. Total score of symptoms (T0: 16.1±7.3) dropped to 11.9±6.6 (T1) (p=0.000) and then to 6.7±5.3 (T2) (p=0.000). Global efficacy expressed by patients and physician was 74.8±15.9 and 76.6±13.0, respectively. No adverse events (blurred vision, allergy) were reported throughout the study. Conclusions. Our study seems to demonstrate that addition of Carbopol 974P to the traditional therapeutic armamentarium for moderate to severe KCS is useful and well accepted in patients with primary SS in which management of ocular symptoms is unsatisfactory
