Ferritin (Ftn), a globular protein, sequesters 4500 atoms of iron per molecule. Elevated serum Ftn levels (hyperferritinemia) is an indicator of iron homeostasis disorders. We present the results of an observational study involving 17 patients with hyperferritinemia unrelated to hereditary hemochromatosis (HH). All participants received treatment with 200 mg of bovine lactoferrin (bLf) once (
Due to different social and epidemiological factors, the eligibility criteria to receive palivizumab prophylaxis may be different between countries, especially in "otherwise healthy" late preterm infants. We analyzed an Italian database of young children referred to emergency departments for acute lower respiratory tract infection (ALRI) during the RSV season over a four year period, when the use of palivizumab as prophylaxis for RSV disease was not widespread in premature infants. The demographic and environmental characteristics and the RSV positivity (RSV+) in hospitalized and not-hospitalized patients were compared. In the data analysis we divided children according to their chronologic age (age) and their week gestational age (wGA). Out of the 100 children evaluated, 68 were infants (≤12 month-age): 7.5 and 20.6 % were in the <29 and 29- < 32 wGA groups respectively, and 72.0 % in the 32- < 35 wGA group. Positive hospitalized-to-not-hospitalized ratios were found in all three wGA groups, progressively decreasing (from 4.0 to 1.2), with increasing wGA (p = 0.35). The percentage of hospitalized infants that were also RSV+ was also progressively decreasing (from 40.0 to 28.6 % and 18.4 %) with increasing wGA (p = 0.43). In the >12 month-age group (N = 32), there was positive hospitalized-to-not-hospitalized ratio only in the <29 wGA group with a low RSV+ frequency (<29 %) in all wGA groups. In the ≤12 month-age group, 41 infants were evaluated with a ≤6 month-age and 27 with a >6–12 month-age. A positive hospitalized-to-not-hospitalized ratios was found in all wGA groups in ≤6 month-age infants, despite a low RSV+ frequency in the 29- < 32 and 32- < 35 wGA group. In the >6-12 month-age group, all infants with a <29 and 29- < 32 wGA were hospitalized with a relatively high RSV+ frequency whilst the 32- < 35 wGA group showed a negative hospitalized-to-not-hospitalized ratio with a lower RSV+ frequency. The hospitalized-to-not-hospitalized ratios and RSV+ frequency in the first 12 months of age in infants born prematurely confirm the vulnerability of these children for clinically important RSV infection, most notably in the <32 wGA category.
Background and objectives:Secondary hyperparathyroidism (SHPT) is a frequent complication of CKD with incidence, prevalence, and costs increasing worldwide. The objective of this analysis was to estimate therapy cost of SHPT in a sub-population of the FARO study.Materials and Methods:In the FARO study, an observational survey aimed to evaluate patterns of treatment in patients with SHPT who had undergone hemodialysis, pharmacological treatments and biochemical parameters evolution data were collected in four surveys. Patients maintaining the same treatment in all sessions were grouped by type of treatment and evaluated for costs from the Italian National Health Service perspective.Results:Four cohorts were identified: patients treated with oral (PO) calcitriol (n = 182), intravenous (IV) calcitriol (n = 34), IV paricalcitol (n = 62), and IV paricalcitol + cinacalcet therapy (n = 20); the cinacalcet monotherapy group was not analysed due to low number of patients (n = 9). Parathyroid hormone (PTH) level at baseline and effectiveness of treatments in suppressing PTH level were assessed to test comparability among cohorts: calcitriol PO patients were significantly less severe than others (PTH level at baseline lower than 300 pg/ml; p < 0.0001); calcitriol IV patients did not reach significant reduction in PTH level. Paricalcitol and paricalcitol + cinacalcet treatment groups results were comparable, while only the IV paricalcitol cohort's PTH level, weekly dosage, and cost decreased significantly from the first to the fourth survey (p = 0.020, p = 0.012, and p = 0.0124, respectively). Total costs per week of treatment (including calcium-based phosphate binder and sevelamer) were significantly lower in the paricalcitol vs paricalcitol + cinacalcet cohort (p < 0.001). Major limitations of this study are related to the survey design: not controlled and lack of comparability between cohorts; however, reflective of true practice patterns.Conclusions:The IV Paricalcitol cohort had significantly lower treatment costs compared with patients treated with paricalcitol + calcimemtics (p < 0.001), without a significant difference in terms of baseline severity and PTH control.
The aim of this analysis was to estimate biochemical parameters and the costs of treatment of secondary hyperparathyroidism (SHPT) in a subpopulation of the FARO-2 study.The FARO-2 observational study aimed at evaluating the patterns of treatment for SHPT in naïve hemodialysis patients. Data related to pharmacological treatments and biochemical parameters (parathyroid hormone [PTH], calcium, phosphate) were recorded at entry to hemodialysis (baseline) and 6 months later (second survey). The analysis was performed from the Italian National Health Service perspective.Two prominent treatment groups were identified, ie, one on oral calcitriol (n=105) and the other on intravenous paricalcitol (n=33); the intravenous calcitriol and intravenous paricalcitol + cinacalcet combination groups were not analyzed due to low patient numbers. At baseline, serum PTH levels were significantly higher in the intravenous paricalcitol group (P<0.0001). At the second survey, the intravenous paricalcitol group showed a higher percentage of patients at target for PTH than in the oral calcitriol group without changing the percentage of patients at target for phosphate. Moreover, between baseline and the second survey, intravenous paricalcitol significantly increased both the percentage of patients at target for PTH (P=0.033) and the percentage of patients at target for the combined endpoint PTH, calcium, and phosphate (P=0.001). The per-patient weekly pharmaceutical costs related to SHPT treatment, erythropoietin-stimulating agents and phosphate binders accounted for 186.32€ and 219.94€ at baseline for oral calcitriol and intravenous paricalcitol, respectively, while after 6 months, the costs were 180.51€ and 198.79€, respectively. Either at the beginning of dialysis or 6 months later, the total cost of SHPT treatment was not significantly lower in the oral calcitriol group compared with the intravenous paricalcitol group, with a difference among groups that decreased by 46% between the two observations. The cost of erythropoietin stimulating agents at the second survey was lower (-22%) in the intravenous paricalcitol group than in the oral calcitriol group (132.13€ versus 168.36€, respectively).Intravenous paricalcitol significantly increased the percentage of patients at target for the combined endpoint of PTH, calcium, and phosphate (P=0.001). The total cost of treatment for the patients treated with intravenous paricalcitol 6 months after entry to dialysis was not significantly higher than the cost for patients treated with oral calcitriol.
Depression in HIV/AIDS patients affects adherence and disease progression and often goes unnoticed. DHIVA is a cross-sectional epidemiologic survey, investigating the prevalence of depression in people living with HIV through use of a validated self-administered scale (CES-D-20), as well and the degree of concordance between the physician's perception and patients' reports. A total of 690 HIV-infected patients attending 24 centers across Italy were enrolled. Concordance was calculated by K statistics. Association between depression and subject characteristics were evaluated through univariate and multivariate logistic models (OR and 95%CI). The prevalence of depressive symptoms was 48.8% from patient's questionnaires and 49.5% from physicians' reports, with a low/fair concordance (K = .38, p < .001). CES-D-20 found severe depression in 22.5% of the patients vs 4% identified by physicians. 135/155 (87%) of the severely depressed patients (according to CES-D-20) were considered as non or mildly/moderately depressed by physicians. Risk of severe depression was associated with unemployment (p < .001), previous depression (p < .001), treatment failure (p = .001), and former smoking status (p = .018). Depression is frequent in HIV-infected patients in the HAART era, with significant discrepancy between physician perception and the self-reported CES-D-20 results. Screening should be mandatory in all HIV patients.
BackgroundChronic kidney disease (CKD) patients affected by mineral bone disorders (MBD) have higher rates of all-cause and cardiovascular-related mortality. Approximately, one-third of dialysis patients have low serum parathyroid hormone (PTH) levels (≤150 pg/mL). However, the reason why these patients have higher mortality compared to patients with normal PTH levels has not yet been fully elucidated.
<b><i>Background:</i></b> Mineral Bone Disorders (MBD) is prevalent in hemodialysis (HD) patients and associated with increased cardiovascular mortality. The FARO-2 study evaluated the achievement of the NKF/K-DOQI guidelines on recommended target values for serum calcium (Ca), phosphorous (P) and intact parathyroid hormone (PTH) levels on survival in incident HD patients. <b><i>Methods:</i></b> Data were collected by questionnaire from 568 incident HD patients followed prospectively over a 3-year period from 26 Italian dialysis units. The cumulative probability of time-to-death for CKD-MBD treatment characteristics was determined by the Kaplan-Meier curves. <b><i>Results:</i></b> Serum PTH levels (median values at 6 months vs. 36 months; 225 vs. 254 pg/ml), Ca (8.8 vs. 8.9 g/dl) and P (5.1 vs. 4.8 mg/dl) were not significantly different at 6 months versus follow-up. The majority of incident HD patients (60-70%) who were followed up for 36 months did not achieve the NKF/K-DOQI recommended target values. Survival rates were higher in patients on target for three parameters versus patients off target (survival at 24 months: at target 95.7% (95% CI: 84.0-98.9) versus not on target 71.1% (95% CI: 66.3-75.4, p < 0.01)). The 30.1% of patients on target for three MBD parameters at least once during the follow-up period had better survival rates compared to those not reaching these targets (survival at 24 months: at least once 88.0% (95% CI: 81.9-92.1); 67.7% (95% CI: 61.9-72.8, p < 0.01)). <b><i>Conclusion:</i></b> Our findings indicate that incident HD patients who achieved target levels (for three MBD parameters) for at least one visit have a lower risk of mortality.
In Italy, few studies have examined the clinical management of peritoneal dialysis (PD) patients, resulting in a lack of information and awareness. A total of 378 PD patients (64.7 ± 14.3 years, 58.9% males) were enrolled across 15 centres in a 12-month retrospective and 6-month prospective study. The primary objective was to evaluate the achievement of Kidney Disease Outcomes Quality Initiative and Kidney Disease Improving Global Outcomes guidelines on recommended target values for anaemia, high blood pressure and mineral metabolism. Comorbidities, hospitalizations, treatment and quality of life were also assessed. Frequent comorbidities included hypertension (87.8%) and cardiovascular disease (39.7%). Peritonitis was the leading cause of hospitalization [12 admissions per 100 person-years (95% confidence interval 9.3–15.2)]. At 6 months, anaemia corrected by erythropoiesis-stimulating agents was observed in 30% of patients and 73% received erythropoiesis-stimulating agents. Systolic and diastolic blood pressures were recorded in 50% and 20% of patients, respectively. Sixty-four percent of echocardiograms revealed left ventricular hypertrophy and 30% of patients had vitamin D <10 ng/mL. Medication to treat intact parathyroid hormone (PTH) included calcitriol (36.3%), paricalcitol (29.2%), cholecalciferol (23.6%) and cinacalcet (21.5%). In a subgroup of patients matched for baseline PTH treated for 1 year, a significant reduction in PTH with paricalcitol (−41%; P < 0.001) but not cinacalcet (+2%; P = 0.63) was observed. Comparison of quality of life domains revealed significant differences for symptoms (P = 0.049), cognitive function (P = 0.019) and social support (P = 0.04) (baseline versus 6 months). Hypertension and cardiovascular diseases were frequent comorbidities and peritonitis was the leading cause of hospitalization. Secondary hyperparathyroidism and anaemia were common, thus necessitating frequent monitoring of PTH, calcium, phosphorus and haemoglobin.
