Testing for Afirma in Thyroid Nodules with High-Risk Indeterminate Cytology (TIR3B): First Italian Experience.

A percentage of 15 to 30% of thyroid fine-needle aspiration (FNA) is indeterminate, i.e., TIR3A and TIR3B according to the Italian consensus for thyroid cytology. Afirma, a molecular analysis of thyroid FNA specimens, has recently gained popularity as an adjunct to microscopic cytological evaluation, in order to avoid diagnostic surgery in patients with indeterminate thyroid cytology. We described the first Italian experience with Afirma tests in a single Italian institution and assessed the performance of the Afirma test in TIR3B. Moreover, this is a preliminary study to assess the patient response to the offer of Afirma testing. The Afirma test was proposed to 67 patients with thyroid nodules that had yielded TIR3B cytology. Fifty-one patients (76.1%) chose the Afirma test, 25/51 underwent the test but the remaining 26 did not because of cost. A total of 41/67 (61.2%) patients underwent surgery, and 22/41 (53.7%) nodules were carcinomas. Of the 25 tested by Afirma, 9 (36%) were classified as Afirma-suspicious (Afirma-S); seven of them underwent surgery, and in 6/7 (85.7%), a cancer was proven at histology. Afirma is the procedure that many Italian patients with TIR3B lesions would choose. However, its routine clinical application in Italy is currently limited by high costs for the patient. When Afirma is performed in this setting of patients, the cancer risk of suspicious result is higher than that expected in all the series of TIR3B. Therefore, testing for Afirma in these nodules may be useful for managing patients and tailoring their surgical approach.

Real-Life Effectiveness and Safety of Golimumab and Its Predictors of Response in Patients with Ulcerative Colitis.

BACKGROUND: Golimumab is a new anti-TNF-alpha monoclonal antibody for patients with ulcerative colitis. AIMS: To assess the short- and long-term effectiveness and safety of golimumab in daily clinical practice and to identify predictors of response. METHODS: Consecutive patients treated with golimumab in 22 Italian centers were enrolled. Clinical, laboratory, and endoscopic data were prospectively collected before and during treatment. A subgroup of patients completed a questionnaire to assess personal satisfaction with a golimumab autoinjector system. RESULTS: A total of 196 patients were included. After 3 months, 130 patients were responders (66.3%) and showed significant reductions in mean partial, total, and endoscopic Mayo scores and in mean ESR, C-reactive protein, and fecal calprotectin levels (p < 0.001). Multivariate analysis revealed that a higher total Mayo score (p < 0.001, OR 1.5, 95% CI 1.2-1.8) and naïve status to anti-TNF-alpha (p = 0.015, OR 3.0, 95% CI 1.2-7.5) were predictive of a favorable response. Seventy-seven (39.3%) of the 130 responders maintained a response at month 12 of therapy. There were 17 adverse events, 28 patients needed hospitalization, and 15 patients underwent surgery. Self-administration of the drug was appreciated by most patients. CONCLUSIONS: The efficacy and safety of golimumab in daily clinical practice were confirmed for the short- and long-term treatment of patients with active ulcerative colitis. Patients naïve to the anti-TNF-alpha monoclonal antibody and those with a higher total Mayo score were more likely to respond to golimumab.

Infliximab biosimilar CT-P13 is effective and safe in treating inflammatory bowel diseases: a real-life multicenter, observational study in Italian primary inflammatory bowel disease centers.

BACKGROUND: The purpose of this study was to assess the efficacy and safety of biosimilar infliximab (IFX) CT-P13 in treating outpatients with inflammatory bowel disease (IBD) in Italian primary gastroenterology centers. METHODS: Consecutive IBD outpatients who completed the induction treatment were evaluated retrospectively. Clinical activity was scored according to the Mayo score for ulcerative colitis (UC) and to the Harvey-Bradshaw Index (HBI) for Crohn's disease (CD). The primary endpoint was the achievement of clinical remission (Mayo score ≤2 in UC and HBI ≤5 in CD). Secondary endpoints were clinical response to treatment, achievement of mucosal healing, and safety. RESULTS: One hundred forty-one patients (96 UC and 45 CD) were enrolled. Previous treatment with anti-tumor necrosis factor (TNF)α had been provided to 26% of UC patients and 28.9% of CD patients. Remission was achieved in 57.3% UC patients and in 75.6% CD patients during a median (interquartile range) follow up of 24 (6-24) months. Clinical response and mucosal healing were achieved in 87.5% and 75.0% of UC patients and in 84.4% and 84.2% of CD patients, respectively. By both univariate and multivariate analysis, age >40 years, presence of comorbidities, and naivety to anti-TNFα were significantly related to remission. Only one (0.7%) adverse event was reported in the CD group. Surgery was performed in 2.1% of UC patients and 6.7% of CD patients. Switching from IFX originator to biosimilar did not influence the maintenance of the clinical remission. CONCLUSION: This study confirmed the long-term efficacy and safety of CT-P13 therapy in IBD, in both naïve patients and those switching from IFX originator.

Vedolizumab is effective and safe in real-life treatment of inflammatory bowel diseases outpatients: A multicenter, observational study in primary inflammatory bowel disease centers.

BACKGROUND: Italian data currently available in managing ulcerative colitis (UC) and Crohn's disease (CD) patients with vedolizumab (VDZ) are coming just from secondary and tertiary centers. The present study aimed to assess the real-life efficacy and safety of VDZ to achieve remission in inflammatory bowel diseases (IBD) outpatients in primary gastroenterology centers. METHODS: Clinical activity was scored according to the Mayo score in UC and to the Harvey-Bradshaw Index (HBI) in CD. The primary endpoints were the achievement of clinical remission and safety. Secondary endpoints were clinical response to treatment, achievement of mucosal healing (MH), and steroid discontinuation. RESULTS: One hundred and thirty-six pts. were enrolled (91 UC and 45 CD pts). During an 18-month median follow-up, clinical remission was present in 63 (46.3%) pts.: in particular, it occurred in 48 (52.7%) patients in UC group and in 15 (33.3%) patients in CD group (p = 0.003). more in UC group. Fecal calprotectin ≥400 µg/g and presence of comorbidities were factors significantly related to the failure of remission in UC and CD, respectively. Ten (7.3%) cases of adverse events were recorded (2 required suspension of treatment). Clinical response was present in 105 (72.2%) pts.: 71 (78.0%) in UC and 34 (75.5%) in CD group. MH occurred in 47 (62.7%) UC and in 9 (50.0%) CD patients. Steroids discontinuation occurred in 92 (67.6%) pts.; 61 (67.0%) UC and 31 (68.9%) CD pts. CONCLUSION: VDZ is effective and safe in IBD outpatients, especially in UC patients.

Raman Spectroscopy Applied to Parathyroid Tissues: A New Diagnostic Tool to Discriminate Normal Tissue from Adenoma.

Primary hyperparathyroidism is an endocrine disorder characterized by autonomous production of parathyroid hormone. Patients with the symptomatic disease should be referred for parathyroidectomy. However, the distinction between the pathological condition and the benign one is very challenging in the surgical setting; therefore, accurate recognition is important to ensure success during minimally invasive surgery. At present, all intraoperative techniques significantly increase surgical time and, consequently, cost. In this proof-of-concept study, Raman microscopy was used to differentiate between healthy parathyroid tissue and parathyroid adenoma from 18 patients. The data showed different spectroscopic features for the two main tissue types of healthy and adenoma. Moreover, the parathyroid adenoma subtypes (chief cells and oxyphil cells) were characterized by their own Raman spectra. The partial least-squares discriminant analysis (PLS-DA) model built to discriminate healthy from adenomatous parathyroid tissue was able to correctly classify all samples in the calibration and validation data sets, providing 100% prediction accuracy. The PLS-DA model built to discriminate chief cell adenoma from oxyphil cell adenoma allowed us to correctly classify >99% of the spectra during calibration and cross-validation and to correctly predict 100% of oxyphil and 99.8% of chief cells in the external validation data set. The results clearly demonstrate the great potential of Raman spectroscopy. The final goal would be development of a Raman portable fiber probe device for intraoperative optical biopsy, both to improve the surgical success rate and reduce surgical cost.

Effectiveness and Safety of Golimumab in Treating Outpatient Ulcerative Colitis: A Real-Life Prospective, Multicentre, Observational Study in Primary Inflammatory Bowel Diseases Centers.

BACKGROUND AND AIMS: Golimumab (GOL) has been recently approved in Italy for the treatment of ulcerative colitis (UC) unresponsive to standard treatments. Our aims were to assess the real-life efficacy and safety of GOL in managing UC outpatients in Italian primary Inflammatory Bowel Diseases (IBD) centres. METHODS: Consecutive UC outpatients with at least 3-months follow-up were enrolled. Primary end-point was the induction and maintenance of remission in UC, defined as Mayo score

Clinical and economic impact of infliximab one-hour infusion protocol in patients with inflammatory bowel diseases: A multicenter study.

AIM: To assess the impact of short infliximab (IFX) infusion on hospital resource utilization and costs. METHODS: All inflammatory bowel diseases (IBD) patients who received IFX 1 h infusion from March 2007 to September 2014 in eight centers from Southern Italy were included in the analysis. Demographic, clinical and infusion related data were collected. The potential benefits related to the short infusion protocol were assessed both in terms of time saving and increased infusion unit capacity. In addition, indirect patient-related cost savings were evaluated. RESULTS: One hundred and twenty-five patients were recruited (64 with ulcerative colitis and 61 with Crohn's disease). Median duration of disease was of 53 mo and mean age of pts at diagnosis was of 34 years (SD: ± 13). Adverse infusion reactions were reported in less than 4% both before and after short infusion. The total number of infusions across the selected centers was of 2501 (30.5% short infusions). In the analyzed cohort, 1143 h were saved (762 in the infusion and 381 in observation phases) through the rapid IFX infusion protocol. This time saving (-15% compared to the standard protocol in infusion phase) represents, from the hospital perspective, an opportunity to optimize infusion unit capacity by allocating the saved time in alternative cost-effective treatments. This is the case of opportunity cost that represents the value of forgone benefit which could be obtained from a resource in its next-best alternative use. Hence, an extra hour of infusion in the case of standard 2-h IFX represents a loss in opportunity to provide other cost effective services. The analysis showed that the short infusion increased the infusion units capacity up to 50% on days when the IFX infusions were scheduled (infusion phase). Furthermore, the analysis showed that the short IFX infusion protocol leads to time savings also in the post-infusion phase (observation) leading to a time saving of 10% on average among the analyzed centers. Finally, the short infusion protocol has been demonstrated to lead to indirect cost savings of €138/patient (average -€17.300 on the whole cohort). CONCLUSION: A short IFX infusion protocol can be considered time and cost saving in comparison to the standard infusion protocol both from the hospital's perspective, as it contributes to increase infusion units capacity, and the patients' perspective, as it reduces indirect costs and the impact of treatment on everyday life and work productivity.

Osteocalcin levels are inversely associated with Hba1c and BMI in adult subjects with long-standing type 1 diabetes.

PURPOSE: Diabetic osteopathy is an upcoming complication of diabetes characterized by osteoporosis, increased risk for bone fractures and alterations in bone metabolism. Osteocalcin (OC) is a bone-specific protein produced by osteoblasts involved in the regulation of glucose and energy metabolism. The aim of this study is to determine whether OC serum levels are correlated with metabolic control in adult subjects with type one diabetes mellitus (T1DM). METHODS: A cross-sectional study was conducted on 93 subjects (51 men) with mean age, disease duration and body mass index (BMI) of 39.9 ± 12.3, 17.2 ± 12.6 years and 24.5 ± 3.4 kg/m(2), respectively. Blood samples were drawn to measure levels of hemoglobin A1c (HbA1c), OC, 25-OH vitamin D and PTH. RESULTS: Significant inverse correlations were found between OC and HbA1c (r = -0.295, P = 0.004) and between OC and BMI (r = -0.218, P = 0.037). These correlations were confirmed also among men in the analyses by gender [HbA1c vs OC: r = -0.363, P = 0.009; BMI vs OC: r = -0.291, P = 0.043], and similar but nonsignificant trends were confirmed among women. A significant difference in mean OC was also found between the lowest and the highest HbA1c tertile (22.3 ± 10.0 vs 16.9 ± 8.0 ng/mL, P = 0.025). CONCLUSIONS: These data show that in T1DM of long duration, OC serum levels are inversely associated with HbA1c and BMI, supporting the hypothesis that a poor glycemic control can affect osteoblast function.

Continuous subcutaneous insulin infusion (CSII) in inpatient setting: unmet needs and the proposal of a CSII unit.

Continuous subcutaneous insulin infusion (CSII) represents an increasingly popular method of treating diabetes. Patients with diabetes are often hospitalized, and current data indicate that inpatient hyperglycemia results in poorer outcomes. When patients on insulin pump therapy require hospitalization, practitioners caring for them face the issue of how to manage the inpatient care of these patients. We believe that patients using insulin pumps can safely have their therapy transitioned when hospitalized. Moreover, CSII during hospitalization should be regarded not only as a fundamental tool in patients already on insulin pump therapy, but also as an effective method to obtain euglycemia, in critically ill patients. However, a standard policy on CSII use during hospitalization is still lacking, and literature data are inconclusive about the benefits of insulin pump on glycemic homeostasis, in hospitalized patients. We suggest that a CSII unit should be activated inside the hospital, in order to increase compliance with required procedures and to properly address the unmet needs of CSII in inpatient setting.

Blue eyes as a risk factor for type 1 diabetes.

BACKGROUND: A high frequency of blue eyes and fair skin are reported in northern European Caucasians with type 1 diabetes (T1D). Also there is an inverse relationship between latitude and T1D incidence. We determined whether iris colour and skin pigmentation are risk factors in a Caucasian population living in two Mediterranean regions located at the same latitude with higher ultraviolet B irradiance, but with different T1D incidence. METHODS: We studied iris colour in 281 consecutive subjects with T1D and 298 controls. Skin type was evaluated by melanin quantification. RESULTS: In Lazio, blue eyes and fair skin type are significantly more common in T1D subjects than in controls (21 versus 9%, p = 0.002; 50 versus 35%, p < 0.001, respectively). In Sardinia, the frequency of blue eyes in T1D subjects is twice that in controls (5.8 versus 2.6% and significantly higher when compared to the expected calculated frequency in the entire population). By logistic regression analysis, only blue eyes are independent and significant predictors of T1D [odds ratio for blue eyes = 2.2; 95% confidence interval (1.1-4.4), p = 0.019]. CONCLUSIONS: As previously shown in a Caucasian population from northern Europe, blue eyes and a trend for fair skin increase the risk for T1D also in a Caucasian population born and residing in a Mediterranean region (Continental Italy). This finding may be relevant for explaining different T1D incidence as prevalence of blue eyes differ substantially between northern and southern European Caucasians.

A novel insulin unit calculator for the management of type 1 diabetes.

BACKGROUND: Intensive insulin therapy is the gold standard therapy for type 1 diabetes (T1D) patients. To achieve optimal glycemic control, adjustments of insulin dose at mealtimes must be made taking into account several parameters: blood glucose levels, insulin/carbohydrate ratio, carbohydrate intake, and physical activity. Calsulin (Thorpe Products Ltd., Cambridge, UK) is a new tool for the administration of insulin dose before each meal. The aim of this study was to evaluate the efficacy of Calsulin on metabolic control in T1D patients undergoing intensive insulin therapy. SUBJECTS AND METHODS: Forty consecutive patients affected by T1D, 18-65 years old, with disease duration of >1 year, were randomized to Calsulin or to the control group. Hemoglobin A1c (HbA1c) was evaluated at entry into the study and at 3- and 6-month follow-ups. Paired t test (two tailed) and analysis of variance were used to evaluate differences in HbA1c at 3 and 6 months in the two groups. RESULTS: HbA1c at entry was 7.9 ± 1.0% (SD) in the Calsulin-treated group and 7.8 ± 1.6% (SD) in control patients (P not significant). Data showed a slight improvement in HbA1c levels at 3 months in the Calsulin-treated group (-0.61% vs. -0.14% difference, respectively; P not significant). At the 6-month follow-up, a significant reduction in HbA1c levels was observed in the Calsulin-treated group versus the control group (-0.85% vs. -0.07% difference, respectively; P < 0.05). CONCLUSIONS: Calsulin is an acceptable and practical tool that makes the process of calculating insulin doses easy to use, and, most importantly, it improves metabolic control as shown by a significant reduction of HbA1c levels.
