RESUMO
BACKGROUND: Vitamin D deficiency (VDD) is common in patients with primary hyperparathyroidism (pHPT), and this could affect the clinical expression of the disease. However, few North American or North European studies have addressed this issue, showing vitamin D repletion in only about one-third of the patients. SUBJECTS AND METHODS: Vitamin D status was evaluated both in an observational study in a series of 206 consecutive patients with pHPT at diagnosis and in a case-control analysis with 113 age- and sex-matched healthy blood donors. Vitamin D status was assessed by measuring plasma 25-hydroxy-vitamin D (25OHD) levels and was defined as VDD or severe VDD if 25OHD was <20 ng/ml (<50 nm) and <10 ng/ml (<25 nm), respectively. RESULTS: No seasonal variability was observed in 25OHD levels. VDD was observed in 75 of 206 patients (36·4%). The VDD was severe in 24 of 75 patients (11·7%). There was no difference in prevalence of VDD between men and women nor between asymptomatic and 'bone and stone' symptomatic patients. 25OHD levels was negatively correlated with parathyroid hormone, ionized calcium, and bone turnover markers, and positively correlated with phosphate. 25OHD levels were also positively correlated with bone mineral density at all sites measured. In the case-control study, the overall prevalence of VDD and severe VDD was higher in patients with pHPT compared with controls (33·6% vs 10·6%, P < 0·0001, and 8·8% vs 1·8%, P = 0·0337, respectively). CONCLUSIONS: Our study shows that VDD occurs in about one-third of patients with pHPT resident in a Southern European area, a lower figure than previously reported. Moreover, VDD is related to a more severe bone disease, and its prevalence is higher in patients with pHPT than in healthy matched subjects.

BACKGROUND: The discharge from the hospital of insulin-treated hyperglycemic patients is always challenging. This is even more so in patients requiring glucocorticoid treatment, such as those with COVID-19. PATIENTS AND METHODS: A retrospective monocentric study of 23 inpatients was conducted with newly diagnosed or already known diabetes mellitus (DM) who were naïve to insulin treatment, and who were hospitalized with COVID-19 in non-critical settings and then discharged. Patients were followed up for one month after discharge for the management of insulin treatment by a multi-professional team through phone consultations. RESULTS: Insulin prescriptions at discharge were 24.6 ± 14 U/day injected in 2 ± 1.5 daily shots. A mean of three phone consultations was required. One month later, the mean insulin reduction was 1.5 ± 1.3 shots and 6 ± 5 U/day. All patients reached their glycemic target without hypoglycemic events, drop-outs, or readmissions. CONCLUSION: This study demonstrates the feasibility, efficacy, and safety of a multi-professional approach through telemedicine for managing DM patients after discharge during COVID-19.

BACKGROUND: The impairment of renal function can affect the clinical presentation of primary hyperparathyroidism (PHPT), increasing cardiovascular morbidity, fracture rate, and the risk of mortality. AIM: The aim of the study was to assess the differences in bone status in a series of consecutive patients affected by PHPT without overt renal failure at diagnosis grouped according to creatinine clearance (Ccr). METHODS: A total of 161 consecutive patients with PHPT were studied. They were divided into two groups based on Ccr. Group A had Ccr 70 ml/min or less (n = 49), and group B had Ccr greater than 70 ml/min (n = 112). PTH, total and ionized serum calcium; urinary calcium and phosphate; serum 25-hydroxyvitamin D3; serum and urinary bone markers; lumbar, forearm, and femoral bone mineral density (BMD) were evaluated. RESULTS: Patients in group A were older than those in group B (P < 0.0001). PTH levels did not differ in the two groups, whereas both urinary calcium and phosphorus were lower in group A than group B (P < 0.01). Lower BMD was evident in group A at lumbar spine (P < 0.002), forearm (P < 0.0001), and femur (P < 0.01). In asymptomatic PHPT, those with Ccr 70 ml/min or less had lower forearm BMD than patients with higher Ccr (P < 0.00001). When adjusting for age and body mass index in PHPT, BMD at each site persisted being lower (P < 0.05) in group A than group B. In all PHPT subjects, Ccr (beta = 0.29, P < 0.0005), age (beta = -0.27, P < 0.00001), and PTH levels (beta = -0.27, P < 0.0005) were all independently associated with forearm BMD. CONCLUSIONS: In PHPT a slight decrease in renal function is associated with more severe BMD decrease, independent of age, body mass index, and PTH levels. This association is also present in asymptomatic PHPT and strengthens the National Institutes of Health recommendations for surgery in patients with mild PHPT.
