Background: In Italy, the adoption of a total lockdown has generated almost total suspension of outpatient visits except for emergencies. Even after lockdown, the pandemic fear created additional barriers to access the health services. The aim of our study is to evaluate the economic impact of the lockdown for COVID-19 on public health in Italy, focusing on its effects on diabetic population., Materials and Methods: We analyzed the impact of the lockdown on excess mortality and morbidity in the Italian diabetic population during 2020. The analysis was divided into several steps: a quantification of specialist visit reduction, the calculation of excess mortality in the diabetic population, the economic evaluation of the slowdown in the use of innovative diabetic therapies. Furthermore, the impact of the lockdown on the reduction of procedures and follow-up visits in diabetic population was evaluated. The overall impact of the pandemic and lockdown effects on costs and quality of life was then calculated., Results: During 2020, a drop of 28% in patient access has been observed. Diabetic patients recorded a twice higher mortality value compared to general population (20.4% vs 10.2%). The analysis of market data revealed a slowdown in consumption of new antidiabetic therapies (-14%, 27% vs 41%). We estimated an expense of €26.6 million for NHS and a loss of 257 utilities in diabetic population due to the missed benefits related to slowdown in innovative antidiabetic drugs use and non-optimal follow-up and control of diabetes complications. In simulation scenarios, we also estimated an overall expenditure ranging from €38.7 to 94.0 million and a loss of 294-836 utilities., Conclusion: Diabetic population paid a high tribute to pandemic and lockdown, both in terms of number of deaths and burden of diabetic complications, together with an overall deterioration of quality of life., Competing Interests: This project was conducted with the support of AstraZeneca.

Background: Patients with malignancy suffer impairment of their quality of life (QoL). QoL has been evaluated in thyroid cancer patients. Since 2010, a new inventory, the thyroid-specific patient-reported outcome (ThyPRO) measure for benign thyroid disorders, has been available., Aim: This study evaluated QoL longitudinally in patients with a history of differentiated thyroid cancer (DTC) by means of the ThyPRO questionnaire. Methods : From 2012 to 2016, QoL was evaluated yearly in 123 adult DTC patients by means of ThyPRO. The ThyPRO questionnaire consists of 13 scales on which higher scores represent greater impact on QoL in areas affected by thyroid pathology. Disease-specific morbidity due to possible inadequate L-T4 treatment was evaluated by means of the Billewicz scale (BS). The same examinations were conducted in 192 control subjects who had undergone surgery for benign thyroid pathology., Results: DTC and control subjects had similar scores on all but one scale; scores on the hyperthyroid symptoms scale were significantly higher in DTC patients than in controls. Over the 5 years, scores did not change significantly in the DTC group. Overall, QoL and BS scores showed a slight, but not significant, improvement during the study period in DTC patients. BMI impacted on several ThyPRO scales. No significant differences between genders were noted in DTC., Conclusions: The ThyPRO questionnaire indicates that illness perception is similar after thyroidectomy for malign and benign pathology. Only a marginal improvement in QoL was noted in DTC subjects over the 5-year study period. In both groups, females showed a greater perception of illness than males., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2019 by S. Karger AG, Basel.)

Purpose: Papillary thyroid microcarcinoma (MPTC) has an excellent prognosis. We aimed to evaluate the evolution of therapeutic strategies over time and the clinical outcome of MPTC., Methods: In this retrospective multicenter observational study in a northwest Italian region, patients with intrathyroidal, unifocal tumor ≤1 cm in size, incidentally found at histology or preoperative cytology diagnosis, were included. Exclusion criteria were a previous head-and-neck irradiation and/or node metastases., Results: From 1985 to 2012, 437 patients had an MPTC diagnosis, which was incidental in 85% and preoperative in 15%. Patients with a preoperative diagnosis were younger at the time of diagnosis (47.6 ± 12.7 years, p < 0.01) and had a larger tumor (7.0 ± 2.5 mm, p < 0.0001) than patients with an incidental diagnosis (age 52 ± 13.5 years, size 4.4 ± 2.8 mm), but there were no differences in clinical outcome between both groups. We observed a significant (p < 0.001) reduction in radioiodine remnant ablation during the years. TSH levels were: <0.1 mIU/l in 27.5%, 0.1-0.5 mlU/l in 33.7%, 0.5-2.5 mlU/l in 32.6%, 2.5-4.2 mlU/l in 3.9%, and >4.2 mlU/l in 2.3% of patients. Six patients (1.37%) had nodal recurrence; 5 of them were cured after therapy. MPTC-linked mortality was null., Conclusions: We confirmed the favorable clinical outcome of MPTC. Despite the reduction in radioiodine ablation, overtreatment of MPTC is still observed.

Differentiated thyroid carcinoma (DTC) generally has a favorable outcome. Thyroid disease, treatments, stress, and comorbidity can compromise health-related quality of life (QoL) and indirectly weigh upon the outcome. From 2004 to 2008, we evaluated QoL longitudinally in 128 DTC subjects. During scheduled examinations, subjects were asked to undergo a semi-structured psychiatric interview and five rated inventories. The same examination was conducted in 219 subjects after surgery for benign thyroid pathology. Low scores represent a better QoL. DTC and control subjects were similar in terms of age, male/female ratio, concomitant psychopharmacological treatments, and frequency of psychiatric diseases. In DTC subjects, Billewicz scale (BS) scores showed an increasing trend over time, especially among females. The ad hoc thyroid questionnaire (TQ) scores were similar in both groups and did not change over time, but at the end of the study ad hoc TQ and BS were significantly related. Ad hoc TQ scores were also related to age on entry to the study. In both male and female DTC subjects, Hamilton's tests for anxiety (HAM-A), but not for depression (HAM-D), showed an improving trend. At the end of the study, HAM-A and HAM-D scores were comparable to those of the control group. HAM-A and HAM-D were both positively correlated with the stage of cancer and the time between diagnosis and treatment. Only HAM-D correlated with age on entry to the study. Kellner symptom questionnaire (KSQ) item scores were higher in DTC subjects than in controls. The change over time in the items including anxiety, somatization, depression, and hostility was significant. Somatization and hostility were more significantly reduced in DTC females than in DTC males. Hostility scores were significantly lower in DTC subjects than in controls at the end of the study. Somatization and depression were significantly related to staging on diagnosis and age on entry to the study. Our study confirms a wide variation of illness perception in DTC subjects, which is generally unrelated to the favorable clinical follow-up of the disease. Psychological evaluation during long-term follow-up improved QoL scores, which reached the same levels noted in subjects with a history of thyroid surgery for benign thyroid pathology. Our data indicate that special attention should be paid to QoL in older DTC subjects and those with more severe staging on diagnosis.

Background: Some extra-thyroid effects of TSH have been described in vitro and in vivo. TSH has recently been suggested to induce interleukin-6 secretion by adipocytes. Leptin is the main protein secreted by adipose tissue., Objective: The aim of our study was to evaluate the acute effect of the recombinant human TSH (rhTSH)-induced TSH surge on serum leptin levels in thyroidectomized patients undergoing levothyroxine (L-T4) suppressive therapy for differentiated thyroid carcinoma (DTC)., Design: A cohort of 15 female DTC patients was evaluated. Standard rhTSH testing was performed. Leptin, TSH, thyroid hormones, and thyroglobulin were measured before and 3, 6, and 9 days after rhTSH testing. Some metabolic parameters were also evaluated at the baseline., Results: Baseline leptin levels were 12.2+/-3.2 microg/l. Only body mass index (BMI) correlated significantly (p<0.05) with leptin levels. After rhTSH administration, TSH levels increased significantly (p<0.001), while thyroid hormones remained unchanged. Twenty hours after the last rhTSH administration, leptin (11.8+/-3.0 microg/l) levels were unchanged. The maximal TSH level was negatively related with BMI (p<0.05), but no correlation between maximal TSH and leptin levels after rhTSH was noted., Conclusions: Our in vivo experimental model suggests that an acute TSH increase after rhTSH testing is ineffective in changing circulating leptin levels.

Hyperthyroidism seems to increase metabolic and cardiovascular risk, while the effects of sub-clinical hyperthyroidism are controversial. We evaluated metabolic and cardiovascular parameters in differentiated thyroid carcinoma (DTC) patients with suppressed thyrotropin (TSH) due to levo-thyroxine (L-T4) therapy. We studied DTC patients and, as a control group, patients with a history of surgery for non-malignant thyroid pathology. Significantly higher insulin and lower HDL-cholesterol levels were recorded in DTC subjects. In both groups, insulin levels were significantly related with body mass index (BMI) but not with age or L-T4 dosage. In DTC patients, a significant negative correlation was seen between HDL-cholesterol and BMI or L-T4 dosage. In both groups, intima-media thickness (IMT) correlated positively with age, BMI, glucose levels and systolic blood pressure. In DTC patients, increased IMT was significantly correlated with glycated hemoglobin (HbA1c), cholesterol and triglycerides. In DTC patients, C-reactive protein correlated positively with insulin, insulin resistance, triglycerides and systolic blood pressure, and negatively with HDL-cholesterol. In both DTC and control subjects, fibrinogen correlated positively with age, BMI, increased IMT, HbA1c and systolic blood pressure. In DTC subjects, plasma fibrinogen concentrations correlated positively with insulin resistance, cholesterol and LDL-cholesterol, and negatively with TSH levels. Our data confirm that the favorable evolution of DTC can be impaired by a high incidence of abnormal metabolic and cardiovascular data that are, at least in part, related to L-T4 therapy. These findings underline the need for adequate L-T4 titration.

Objective: Some extra-thyroid actions of thyroid stimulating hormone (TSH), such as an in vitro action on bone, have been described. Our aim was to evaluate in vivo the acute effect of a recombinant human TSH (rhTSH)-induced TSH surge on Osteoprotegerin (OPG) and receptor activator of the nuclear factor-kappaBeta (RANK-L) levels in patients under levo-thyroxine (L-T4) therapy., Design: 24 patients with differentiated thyroid carcinoma (DTC) were studied. Standard rhTSH testing was performed. OPG, RANK-L, TSH, thyroid hormones, thyroglobulin and several parameters of bone metabolism were evaluated., Results: Baseline OPG and RANK-L levels were in the range of our reference population. An inverse correlation between OPG and spinal Z-score (p=0.029) and between RANK-L and age (p=0.018) or urinary calcium/creatinine ratio (p=0.011) was detected. After rhTSH administration, a significant (p<0.001) increase in TSH was found. No significant increase in OPG or RANK-L levels after rhTSH was observed. No correlation was detected between TSH peak value after rhTSH and maximal percentage change in OPG or RANK-L. A slight increase in urinary cross-links after rhTSH was found., Conclusions: In a small group of subjects with a history of DTC on L-T4 regimen, our study did not support an acute direct effect of TSH on OPG and RANK-L.

Overt hyperthyroidism is associated with changes in bone metabolism, whereas the effect of levothyroxine (L-T4) load in patients with differentiated thyroid carcinoma (DTC) is controversial. The aim of our study was to evaluate osteoprotegerin (OPG) and soluble receptor activator of nuclear factor kappaB ligand (RANK-L) in patients with DTC with suppressed endogenous thyrotropin due to L-T4 regimen. A cohort of 80 subjects with DTC (68 women and 12 men; age range, 27-81 years) was studied. A cohort of 55 subjects with a history of partial or total surgery for nonmalignant thyroid pathology served as a control group. Groups were matched for sex, age, and body mass index. Per-week dosage of L-T4 was significantly higher in patients with DTC than in controls (P < .001). More elevated free T(4) concentrations (P < .001) and more suppressed thyrotropin and thyroglobulin levels (P < .001) were found in subjects with DTC than in controls. No difference in serum or urinary parameters related to bone metabolism or dual-energy x-ray absorptiometry was noted between the groups. Overall, OPG levels were similar in both groups but were significantly (P = .03) lower in postmenopausal women with DTC than in postmenopausal control women. Only control women showed lower OPG levels in premenopausal than in postmenopausal (P = .002) conditions. Overall, RANK-L levels were significantly higher (P = .03) in subjects with DTC than in controls. In both groups, OPG and RANK-L levels were unrelated to each other. A significant positive correlation was seen between OPG levels and age in both subjects with DTC (P < .001) and controls (P < .001). Serum RANK-L correlated negatively with age in subjects with DTC (P = .05). Although there were several differences in L-T4 dosages, OPG and RANK-L levels were similar in patients with a history of DTC and those with a history of nonmalignant thyroid diseases. The correlation between circulating OPG and RANK-L levels was not significant. The increase in OPG with age indicates its protective role in bone loss. The cause of bone loss after long-term L-T4 load will be more extensively studied.
