Aims This study aimed to investigate the relationship between cardio-ankle vascular index (CAVI) and diabetic retinopathy (DR) in Caucasian patients with type 2 Diabetes Mellitus (T2DM). Methods This was a cross-sectional study of 299 T2DM patients admitted to Endocrine Unit of Foggia. DR was diagnosed using the International Clinical Disease Severity Scale of American Academy of Ophthalmology. The VaSera VS-1500N was used to measure CAVI. Because age is the most powerful determinant of arterial stiffness and affects the progression of DR, we divided the whole sample into two subgroups: above (older) and below (younger) 70 years. Results The mean age of patients was 60.4 ± 12.6 years and the mean CAVI value was 8.6 ± 1.7. In the whole population DR was diagnosed in 74 (24.7%) patients. CAVI value was clearly higher in patients with DR (9.5 ± 1.6) than in those without (8.7 ± 1.7) (P = 0.001) although this difference was not any more significant when adjusted by age and gender (P = 0.067). In the multivariate model taking into account several possible confounders, the correlation between DR and CAVI remained significant only in younger subjects. In the same subgroup we found a significant association between the stages of DR and CAVI (p = 0.019 adjusted by age and gender). Conclusions This study shows that CAVI is significantly higher in younger patients with DR than in those without, with a relationship between the stages of DR and CAVI in the same subgroup. Physicians should pay attention to sub-clinical macroangiopathy in younger T2DM patients who have DR.

Primary pigmented nodular adrenocortical disease (PPNAD), an uncommon cause of Cushing’s syndrome, is frequently associated with a wider clinical spectrum, the Carney complex (CC), a multiple endocrine neoplasia syndrome. We evaluated a low-dose mitotane regimen for treating severe hypercortisolism in a 27-year-old woman with CC. She presented with severe hypercortisolism and a history of surgeries for breast ductal adenoma, atrial cardiac myxomas with cerebral and peripheral arterial embolism, and near-total thyroidectomy because of an oxyphilic adenoma. The patient refused further surgery for adrenalectomy. During the first 7 months of mitotane (Lysodren, HRA Pharma, Paris, France), the daily oral dose was progressively increased from 0.5 to 4 g/day and then stopped because of the appearance of sustained signs of hypoadrenalism, that required a replacement therapy with 5 mg of prednisone o.d. A 10-month mitotane off-therapy follow-up was performed and when an increase in urine free Cortisol (UFC) was noted, the mitotane regimen was restarted at lower doses (0.750–1 g/day). Serum morning Cortisol levels and UFC were then maintained within the normal range, with plasma mitotane ranging between 2 and 4 mg/L. A sustained regression of Cushing’s features without inducing hypoadrenalism was achieved, which still persists after 122 months of follow-up. Minimal initial gastric discomfort was the only side effect of which the patient complained and only during the first higher dose mitotane course. Long-term administration of a low maintenance dose of mitotane may be suggested as treatment for hypercortisolism in CC patients who refuse or are at high risk for surgical adrenalectomy.

Objective To evaluate lymphocyte subset distribution in the secretory endometrium from infertile patients with polycystic ovary syndrome (PCOS), and the expression of the cytokines known to play a role in determining the endometrial lymphocyte pattern. Design Experimental clinical study. Setting Outpatient clinic in a university hospital. Patient(s) Twenty-eight patients with PCOS (PCOS group) and 6 fertile patients (control group). Intervention(s) On days 22–26 of a spontaneous cycle, subjects underwent endometrial biopsies. Main Outcomes Measure(s) In 19 of 28 patients with PCOS and 6 controls with a late secretory endometrium, the percentage and phenotype of lymphocyte subsets were analyzed by flow cytometry. In the late secretory endometrium of 11 patients with PCOS and 3 controls, the expression of interleukins 15 and 18 and of chemokine ligand 10 was also analysed by polymerase chain reaction. Result(s) In patients with PCOS the percentage of CD56+/CD16− and of CD56 bright /CD16− cells was significantly lower (median [confidence interval]: 38% [31%–52.7%] vs. 63.7% [57.7%–69%] and 17.4% [8%–41.6%] vs. 52% [43%–60%], respectively), whereas the percentage of CD3+ was significantly higher (45% [33.3%–64%] vs. 26.1% [21%–32%]) as compared with controls. Accordingly, polymerase chain reaction analysis revealed a significantly lower expression of interleukins 15 and 18 and of chemokine ligand 10 in patients with PCOS than in controls. Conclusion(s) Results demonstrated an abnormal percentage of endometrial lymphocyte subsets, associated with an impaired cytokine network in patients with PCOS. This could explain the poor reproductive potential in these patients.

A low-dose mitotane (MT) regimen was evaluated as a pharmacological approach for correcting the severe hypercortisolism in a young woman affected by Carney complex (CNC) and primary pigmented nodular adrenocortical disease (PPNAD). In the first 12 week period, the MT daily dose was progressively increased from 0.5 to 4.0 g/day. This dosage was maintained for an additional 16 weeks (cumulative dose 602 g, plasma MT maximum level 12 microg/ml), and then stopped because of sustained signs of hypoadrenalism requiring prednisone replacement. Complete regression of seborrhea, acne, and plethora was observed after 8 weeks of treatment (cumulative dose 95 g). Regular menses returned after 13 weeks (cumulative dose 197 g, plasma MT 8 microg/ml). Profound decrease of both serum cortisol (from 615 to 220 nmol/l) and urinary free cortisol (UFC) values (from 1498 to 477 nmol/day) was noted after 16 weeks of treatment (cumulative dose 314 g, plasma MT 8 microg/ml). MT treatment was associated with mild gastric discomfort and reversible increase of cholesterol plasma levels. Low serum cortisol and UFC were still observed 41 weeks after MT was discontinued (plasma MT 0.2 microg/ml). Our report demonstrates that low dose MT treatment may be a safe and effective modality for a sustained correction of hypercortisolism by PPNAD in subjects with CNC waiting for surgery.

Cystic changes in metastatic cervical lymph nodes (CLN) from papillary thyroid cancer (PTC) may be a diagnostic pitfall in fine-needle aspiration biopsy (FNAB) cytology. We investigated in a series of CLN metastases from thyroid cancers (TC), including cystic PTC, and from a wide spectrum of extrathyroidal malignancies, the diagnostic role for metastatic TC of the rapid detection of thyroglobulin in eluates from FNAB (FNAB-Tg) of CLN. The study was carried out in a group of 79 subjects (22/57 M/F; median age, 56 years; range, 20-86 years) with enlarged CLN and thyroid nodules (TN), examined for potential metastatic TC, and harboring a large spectrum of incidentally diagnosed extrathyroidal malignancies (n = 24, mostly represented by lymphomas, lung, and breast cancers), CLN metastases from thyroid cancers (n = 28, including 6 cystic metastatic PTC), 6 specific lymphadenitis and 21 reactive lymphadenitis mostly detected (n = 16) during follow-up of patients with previously ablated TC. Markedly high FNAB thyroglobulin (Tg) values were found in all metastatic CLN TC. Two of the six cases with cystic metastatic CLN PTC were diagnosed by FNAB-Tg but not by cytology. In conclusion, FNAB-Tg has been confirmed as an easy modality and fast procedure to diagnose CLN metastasis from TC and high FNAB-Tg values with nondiagnostic cystic cytology strongly suggest cystic metastatic PTC.

To investigate the influence of obesity and body fat distribution on serum levels of ceruloplasmin, a risk factor for myocardial infarction.Fasting concentrations of ceruloplasmin, insulin, glucose, lipid pattern (cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides), blood pressure levels, and body fat distribution were determined in a population of non-diabetic subjects.University Hospital Outpatient Clinic.87 consecutive individuals (35 men and 52 women), represented by 27 normal weight (BMI:25.0), 20 overweight (BMI:25.0-30.0) and 40 obese (BMI:30.0) subjects.Serum insulin levels were quantified by radioimmunoassay, plasma glucose and lipid concentrations by enzymatic assays, and serum ceruloplasmin by nephelometry. Intra-abdominal thickness was measured by ultrasound technique.Ceruloplasmin levels were significantly (P0.001) higher in obese (36.5 +/- 8.60 mg/dl) than in overweight (30.4 +/- 6.17 mg/dl) and normal weight (29.3 +/- 8.06 mg/dl) subjects. Of several variables associated with ceruloplasmin (BMI, waist circumference, WHR, intra-abdominal thickness, triglycerides, cholesterol, LDL-cholesterol, insulin), only triglycerides (in both men and women) and ultrasound intra-abdominal thickness (in women) maintained a significantly independent relationship with this protein in multiple stepwise analysis. Moreover, both triglycerides and total cholesterol maintained an independent correlation with ceruloplasmin when the data from both men and women were pooled together.This study indicates that patients with central obesity have characteristically higher ceruloplasmin serum levels, and that ceruloplasmin concentrations are strongly correlated with serum triglyceride and cholesterol levels (in both sexes) and visceral fat accumulation (in women), independently of the other associated cardiovascular risk factors (insulin and blood pressure levels). Since ceruloplasmin has been shown to increase in response to the atherosclerotic inflammatory process, and to promote coronarosclerosis, the determination of serum ceruloplasmin in subjects with central obesity might be a useful tool to identify patients with the highest risk for myocardial infarction.
