    ABSTRACT: Neridronate is a third generation bisphosphonate with established efficacy in metabolic bone disease. In this randomized, open-label study, 118 adults with β-thalassaemia and bone mineral density (BMD) Z scores ≤-2·0 were randomized 1:1-500 mg calcium with 400 international unis (iu) vitamin D daily or 500 mg calcium with 400 iu vitamin D daily plus neridronate 100 mg intravenously every 90 d. Significant increases in BMD at the lumbar spine and total hip were noted in the neridronate group at 6 and 12 months from baseline (P < 0·001), and values were significantly higher than the control group at both time intervals. Neridronate also significantly decreased serum bone alkaline phosphatase and C-telopeptide of collagen type 1 levels from as early as 3 months (P = 0·04 and P < 0·001, respectively), reaching significantly lower values at 12 months compared with the control group (P < 0·05). Reductions in back pain and analgesic use were also evident, starting 3 months from commencing treatment. Treatment was well tolerated by all patients. In this largest randomized trial in thalassaemia-induced osteoporosis to date, neridronate was safe and effective in reducing bone resorption and increasing BMD. The associated reduction in back pain and improved quality of life will encourage adherence to therapy. (Clinicaltrials.gov identifier NCT01140321.).

    ABSTRACT: The aim of the study was to estimate the absolute risk of fracture in a sample of postmenopausal women with the Italian version of FRAX®, using femoral neck bone mineral density (BMD) and 3 internationally validated clinical risk factors (CRFs) (history of fragility fracture, family history of hip fracture, current smoking). We retrospectively studied 9586 women (mean age 64.1 yr) examined in three osteoporosis centers from Northern Italy over two years (2001-2002). The risk of major osteoporotic (clinical spine, hip, forearm and humerus) and hip fractures was estimated using the online version of the FRAX algorithm adapted for Italy. The median 10-year risk was 7.5% for osteoporotic fracture and 1.7% for hip fracture. 25% of subjects had a 10-year risk ≥ 12.1% for osteoporotic fracture and ≥ 4.1% for hip fracture. The median 10-year risk of fracture increased with the number of prevalent CRFs. For major osteoporotic fractures risk rose from 6.3% to 10.9%, 21.4% and 40.9% with 1, 2 and 3 prevalent CRFs, respectively. For hip fractures the corresponding figures were: 1.3%, 2.7%, 7.0% and 21.9%, respectively. However, it must be emphasized that in 2 out of 3 women, none of the CRFs examined was present and the assessment of risk was limited to age and BMD. Our data provide the first description of the effect of the combination of BMD, age and CRFs on fracture risk stratification in a large sample of Italian postmenopausal women using FRAX®. The results are a useful starting point to define criteria for the application of FRAX® in clinical practice in Italy.

    ABSTRACT: To compare the effects on parathyroid hormone (PTH) and 25-hydroxy-vitamin D (25(OH)D) of two dosing regimens of cholecalciferol in women with secondary hyperparathyroidism (sHPTH) and hypovitaminosis D and to investigate variables affecting 25(OH)D response to cholecalciferol. Randomized-controlled trial with 6-month follow-up. Two osteoporosis centers in northern Italy. Sixty community-dwelling women aged 65 and older with sHPTH and hypovitaminosis D, creatinine clearance greater than 65 mL/min and without diseases or drugs known to influence bone and vitamin D metabolism. Cholecalciferol 300,000 IU every 3 months, once at baseline and once at 3 months (intermittent D(3) group) or cholecalciferol 1,000 IU/day (daily D(3) group). Serum PTH, 25(OH)D, calcium, bone-specific alkaline phosphatase, β-C-terminal telopeptide of type I collagen, phosphate, 24-hour urinary calcium excretion. The two groups had similar baseline characteristics. All participants had vitamin D deficiency [25(OH)D<20 ng/mL)], and 36 subjects (60%) had severe deficiency (<10 ng/mL), with no difference between the groups (severe deficiency: intermittent D(3) group, n=18; daily D(3) group, n=18). After 3 and 6 months, both groups had a significant increase in 25(OH)D and a reduction in PTH. Mean absolute increase ± standard deviation of 25(OH)D at 6 months was higher in the intermittent D(3) group (22.7±11.8 ng/mL) than in the daily D(3) group (13.7±6.7 ng/mL, P<.001), with a higher proportion of participants in the intermittent D(3) group reaching desirable serum concentration of 25(OH)D≥30 ng/mL (55% in the intermittent D(3) group vs 20% in the daily D(3) group, P<.001). Mean percentage decrease of PTH in the two groups was comparable, and at 6 months, a similar proportion of participants reached normal PTH values. 25(OH)D response to cholecalciferol showed a wide variability. In a logistic regression analysis, body mass index and type of treatment appeared to be significantly associated with normalization of 25(OH)D values. Cholecalciferol 300,000 IU every 3 months was more effective than 1,000 IU daily in correcting vitamin D deficiency, although the two groups achieved similar effects on PTH at 6 months. Only 55% of the higher-dose intermittent group reached desirable concentrations of 25(OH)D, suggesting that yet-higher doses will be required for adequate vitamin D repletion.

    ABSTRACT: Idiopathic hypercalciuria (IHC) is defined as a 24-hour urinary calcium excretion that exceeds 4 mg/kg/day, regardless of gender and in absence of systemic diseases or pharmacological treatments that may cause normocalcemic hypercalciuria (eg sarcoidosis, normocalcemic primary hyperparathyroidism, vitamin D intoxication, hyperthyroidism). Patients with IHC and nephrolithiasis often present increased bone turnover, decreased bone mineral density (BMD) and increased susceptibility to fragility fractures. Although the pathogenesis of IHC seems complex and multifactorial, recent evidences suggest that cells involved in bone resorption may play a critical role in the chain of events leading to the excessive urinary calcium excretion. Therefore, it has been proposed that bisphosphonates, potent inhibitors of bone resorption, may have beneficial effects in hypercalciuric patients with low BMD. This manuscript reports recent findings regarding the role of bone tissue in the pathogenesis of IHC, and supports the use of bisphosphonates in such conditions. It also reviews the literature on the effects of bisphosphonates in subjects with osteoporosis-associated IHC.

    ABSTRACT: To evaluate baseline characteristics and in-hospital factors associated with nonadherence with an immediate weight-bearing and early ambulation (IWB-EA) program after hip fracture (HF) surgery. Prospective inception cohort study. Ortho-geriatric unit in an acute care hospital. Older adults (N=469) admitted with an osteoporotic HF who underwent surgery. Immediate weight-bearing and assisted ambulation training on the first postoperative day (all patients). Proportion of subjects who adhered to the IWB-EA protocol within 48 hours of surgery. A total of 366 patients (78%) bore weight and ambulated within 48 hours (weight-bearing [WB] group) while the others did not adhere to the protocol (nonweight-bearing [NWB] group). Subjects in the NWB group were significantly older, were more cognitively and functionally impaired, and presented a higher comorbidity at baseline. A higher proportion of subjects in the NWB group (42.7%) than the WB group (23.5%; P<.001) underwent surgery on a preholiday day. In multivariate analysis, having surgery on Friday or a preholiday day (the day before a public holiday) remained the most influent variable related to nonadherence to the IWB-EA protocol (odds ratio=2.5; 95% confidence interval=1.6-4.0; P<.001). This study establishes that IWB-EA is feasible in a high proportion of patients after surgical stabilization of HF. Neither cognitive impairment nor high comorbidity influenced significantly the adherence to the protocol, indicating that IWB-EA may be offered to an unselected population of the elderly with HF. The day of surgery (eg, preholiday or not) was the only variable influencing the participation to the IWB-EA protocol, suggesting the importance of maintaining the same standard of daytime care every day of the week.

    ABSTRACT: The role of bisphosphonates (BPs) in the management of patients with hypercalciuria (HC) associated with osteoporosis is still uncertain. The aim of the study was to evaluate the effect of alendronate and indapamide alone or in combination on bone mineral density (BMD) and 24-h urinary calcium excretion (24-CaU) in post-menopausal women with HC and low BMD. A total of 77 post-menopausal women with HC (24-CaU > 4 mg/kg/day) and low BMD [T-score < -2.0 at lumbar spine (LS), femoral neck (FN) or total hip (TH)] from two centres of Northern Italy were randomized to receive indapamide 2.5 mg daily alone (24 patients, IND group), alendronate 70 mg weekly alone (27 patients, ALN group) or the combination therapy (26 patients, ALN + IND group). Throughout the study, all subjects received daily calcium supplements, depending on their dietary intake, to maintain a daily input of 1000 mg. Patients were instructed to increase water intake up to 2000 mL daily. The percentage and absolute changes of BMD at LS, FN and TH, and the variation of 24-CaU from baseline at 1 year were the primary outcomes. Serum calcium, phosphate, parathyroid hormone and bone alkaline phosphatase were also measured. Overall 67 women completed the study and were included in the final analysis. Patients in the three groups were similar with regard to baseline characteristics. BMD did not significantly change from baseline after 1 year of treatment with indapamide (LS: +1 +/- 3.1%; FN: -0.3 +/- 3.5%; TH: -0.4 +/- 3.1%), while it showed a significant increase from baseline in the other two groups (ALN; LS: +5.8 +/- 4.2%, P < 0.001; FN: +3.9 +/- 7.9%, P = 0.018; TH: +2 +/- 3.6%, P = 0.006) (ALN + IND; LS: +8.2 +/- 5.3%, P < 0.001; FN: +4.9 +/- 6.7%, P = 0.007; TH: +2.9 +/- 4.2%, P = 0.004). Patients in the combination group showed a significantly higher increase of BMD at LS compared to ALN (P = 0.04). After 1 year, 24-CaU values significantly decreased from baseline in all groups (IND, 239 +/- 78 versus 364 +/- 44, P < 0.001) (ALN, 279 +/- 68 versus 379 +/- 79, P < 0.001) (ALN + IND, 191 +/- 68 versus 390 +/- 55, P < 0.001). The mean percentage decrease of 24-CaU in ALN + IND group (-50%) was significantly greater compared to ALN (-24%, P < 0.001) and IND (-35%, P = 0.012). These results show a benefit, in terms of BMD improvement and 24-CaU reduction, associated with BPs' therapy in combination with indapamide in HC associated with osteoporosis. The combination therapy demonstrated a reduction of 24-CaU and an increase in LS BMD superior to that observed with alendronate alone. Our results support a new potential approach with BPs associated with thiazide diuretics or indapamide in the management of post-menopausal women with HC and associated bone loss. Studies on the larger sample size are needed to demonstrate the efficacy on the fracture outcome.

    ABSTRACT: All hip fracture (HF) subjects are candidates for calcium and vitamin D (CaD) supplementation. Up to 50% of HF older adults present with secondary hyperparathyroidism (HPTH) resulting from hypovitaminosis D on hospital admission. To investigate the patterns and predictors of persistence with CaD supplementation in the elderly after HF, we considered all patients aged 70 years or older who were discharged alive after surgical repair of HF in the period of 1 year from an Orthopaedic Unit. Baseline characteristics of the subjects and osteoporosis treatment prescribed at discharge were retrieved from medical record review. A telephone interview at 6 months evaluated whether patients were currently taking CaD supplementation. Nonpersistence was defined when subjects ceased therapy within 6 months. Univariate and multivariate models were applied to determine the relationship between 6 months persistence with CaD and the variables collected: age, living situation, prescription of a bisphosphonate, baseline walking ability, number of drugs used, presence of dementia, number of active clinical issues at discharge (ACIs), discharge location, and being referred to a center for metabolic bone diseases (preplanned visit) at discharge. Of 428 subjects enrolled, 117 were excluded for different reasons (incomplete data, no therapy, death). A total of 311 subjects were discharged with a prescription of CaD (calcium 1,000 mg, cholecalciferol 800 UI, once daily) and were considered for the analysis. At 6 months, only 114 patients (36.7%) were currently taking CaD supplementation. In a univariate analysis, the following variables were significantly related with persistence: absence of dementia, prescription of a bisphosphonate, six or fewer drugs being used (drugs used <or=6), two or less ACIs (<or=2 ACIs) at discharge, ability to walk without aid at baseline, being discharged home, and being referred to a preplanned visit. In a multivariate model, the prescription of a bisphosphonate at discharge (OR 3.178, 95% CI 1.477-6.836, P = 0.003), a preplanned visit (OR 1.953, 95% CI 1.066-3.514, P = 0.03), the absence of dementia (OR 1.877, 95% CI 1.021-3.451, P = 0.043), and <or=6 drugs used (OR 1.842, 95% CI 1.066-3.182, P = 0.029) remained the most significant predictors of persistence with CaD. In HF elderly, who are at high risk of hypovitaminosis D and HPTH, persistence with CaD supplementation is very low. The enrolment in a postsurgical program for the management of bone disease can significantly increase persistence. Moreover, factors related to the complexity of older adult patients (polypharmacotherapy, dementia) seem to be particularly important in compliance with prescribed drugs.

    ABSTRACT: Compliance to osteoporosis treatment with oral bisphosphonates is very poor. Intermittent intravenous bisphosphonate is a useful alternative, but this route is not readily available. Neridronate, a nitrogen-containing bisphosphonate that can be given intramuscularly (IM), was tested in a phase 2 clinical trial in 188 postmenopausal osteoporotic women randomized to IM treatment with 25 mg neridronate every 2 weeks, neridronate 12.5 or 25 mg every 4 weeks, or placebo. All patients received calcium and vitamin D supplements. The patients were treated over 12 months with 2-year posttreatment follow-up. After 12-month treatment, all three doses were associated with significant bone mineral density (BMD) increases at both the total hip and spine. A significant dose-response relationship over the three doses was observed for the BMD changes at the total hip but not at the spine. Bone alkaline phosphatase decreased significantly by 40-55% in neridronate-treated patients, with an insignificant dose-response relationship. Serum type I collagen C-telopeptide decreased by 58-79%, with a significant dose-response relationship (P < 0.05). Two years after treatment discontinuation, BMD declined by 1-2% in each dose group, with values still significantly higher than baseline at both the spine and the total hip. Bone turnover markers progressively increased after treatment discontinuation, and on the second year of follow-up the values were significantly higher than pretreatment baseline. The results of this study indicate that IM neridronate might be of value for patients intolerant to oral bisphosphonates and unwilling or unable to undergo intravenous infusion of bisphosphonates.

    ABSTRACT: To determine whether secondary hyperparathyroidism (HPTH) due to hypovitaminosis D affects bone mineral density (BMD) response to alendronate (ALN) in elderly women with osteoporosis. Randomized, controlled trial with 1-year follow-up. Two osteoporosis centers in northern Italy. Community-dwelling women aged 60 and older with a BMD T-score below -2.5 and secondary HPTH with vitamin D insufficiency. One hundred twenty subjects were randomly assigned to receive ALN 70 mg once a week alone or ALN 70 mg once a week plus calcitriol (1,25D3) 0.5 microg daily. BMD measured using dual-energy x-ray absorptiometry at the lumbar spine (L1-L4), femoral neck, and total hip and serum levels of intact PTH at baseline and 12 months. After 1 year, BMD of the lumbar spine, femoral neck, and total hip significantly increased from baseline in both groups (P<.001). Patients allocated to ALN plus 1,25D3 demonstrated a significantly higher increase in lumbar spine BMD than those receiving ALN alone (mean percentage+/-standard deviation 6.8+/-4.6 vs 3.7+/-3.2, P<.001). Serum levels of PTH did not change significantly at 1 year in the ALN group (mean percentage, -3.7+/-27.1, P=.13) but decreased significantly in the ALN plus 1,25D3 group (-32.1+/-22.1, P<.001). At 12 months, subjects with normalized PTH independent of therapy allocation had a greater increase in lumbar spine BMD than those with persistent HPTH (6.5+/-4.6% vs 3.7+/-3.4%, P<.001). Lumbar spine BMD changes showed a significant negative correlation with PTH at 1 year (correlation coefficient (rho) =-0.399, P<.001) and a positive correlation with PTH changes (i.e., baseline value - 1 year value; rho=0.295, P=.005). Persistence of secondary HPTH reduces BMD response to ALN in older women with osteoporosis.

    ABSTRACT: The aim of the present study was to evaluate the clinical presentation, characteristics and post-surgical outcome of non-functioning pituitary macroadenomas (NFPM) in elderly patients. 27 patients (65-81 years; 13 Males, 14 Females) with NFPM (20-45 mm in diameter) were studied. The symptoms prompting neuroradiological studies were vision alterations in 52%, and dizziness, loss of memory, confusion, headache and depression in 29%; in 19% of patients, the disease was incidentally discovered during computed tomography (CT) or magnetic resonance imaging (MRI) for head trauma or cerebral ischemic attacks. Endocrinological evaluation on diagnosis showed global anterior hypopituitarism in 33% and partial hypopituitarism in 37% of patients. Immunohistochemistry showed signs of neurosecretion in most NFPM (chromogranin-A in 55%, gonadotropins in 19%, ACTH in 3.7%). Ki-67 antigen expression was indicative of low proliferative activity. Surgery was highly effective in improving alterations in vision and compressive symptoms, but was unable to restore normal pituitary function in established hypopituitarism in most cases. Eight patients (31%) were free of disease on subsequent MRI (follow-up 1-6 years). In 18 (69%) patients, a post-surgical residue was present. Of these, 6 (33%) underwent radiotherapy in the following years, owing to an increase in the volume of the remnants, and six (33%) underwent additional surgical treatment, followed by radiotherapy for further signs of growth in two. In the remaining patients, a small intrasellar remnant was stable on yearly MRI. in elderly patients, the development of hypopituitarism is often overlooked and the initial diagnosis of NFPM may be delayed. This can expose patients to the risks of unrecognized hypopituitarism and jeopardize post-surgical outcome.

    ABSTRACT: The study investigates one-year mortality risk associated with hip fracture in elderly people, and pre-fracture characteristics and events occurring during the acute phase which may represent significant predictors for acute and long-term mortality. The study is a prospective cohort study of 252 patients aged 70 and older, consecutively admitted with hip fracture to the Division of Orthopedic Surgery of the Galliera Hospital of Genoa, Italy. At admission, each subject received a standardized diagnostic evaluation, including demographic variables, biochemical markers of nutritional status and basic medical, functional and cognitive assessment. Patients were followed by telephone interviews at three months, six months and one year after fracture. The relationship between mortality and the risk factors recorded was assessed using logistic regression models. 248 patients were eligible. Cumulative mortality was 4.8% during hospital stay, and 12.5% at 3, 18.9% at 6 and 24% at 12 months. The risk factors significantly associated with mortality were: sex, Acute Physiology Score (APS), comorbidity, functional and cognitive status, and albumin levels. In multivariate models, albumin below 3 g/dL remained the only significant predictor of in-hospital mortality (OR 6,8, 95% CI 1.56-29,7, p<0.001); functional status and comorbidity were significant risk factors of mortality after 6 and 12 months. These findings confirm the important role of serum albumin in assessing in-hospital health status and defining its role as a strong predictor of early and late mortality after hospital discharge. They also emphasize the effects of comorbidity and functional impairment on long-term mortality after hip fracture. Identifying these predictive factors may be helpful in improving case management during hospital stay and more accurate discharge planning.

    ABSTRACT: To determine and compare the prevalence of secondary hyperparathyroidism (HPTH) in a population of community-dwelling and institutionalized older adults hospitalized with and without hip fracture, and to evaluate factors correlated with secondary HPTH in this population. Circulating concentrations of serum intact PTH, 25-hydroxyvitamin D [25(OH)D] total serum calcium and albumin were measured in 160 subjects with an osteoporotic fracture of the proximal femur and in 160 matched controls hospitalized for a disease unrelated to bone status. Patients with secondary causes of bone loss and taking medications affecting bone metabolism were excluded. Age, sex, place of residence and the ability to perform basic activities of daily living (BADL) two weeks before hospital admission were recorded at baseline. Patients were comparable with regard to the baseline demographic, biochemical and functional characteristics. The overall prevalence of secondary hyperparathyroidism was 51.2%, without significant differences between hip fractured patients and controls (50.6 vs 51.9%, p=0.911). In bivariate analysis only the age and functional status (BADL) demonstrated a significant relationship with secondary HPTH, while sex and place of residence were not significant. These results were also confirmed in multivariate analysis. Particularly, the risk of secondary HPTH increased with age and with the number of functions lost in BADL: patients fully dependent showed a 3 times as high risk (odd ratio 3.07, 95% confidence interval 1.73 to 5.46, p=0.000) compared to patients independent in BADL, and subject aged >88 yr had a twice as high risk of developing secondary HPTH compared to younger ones (odd ratio 2.28, 95% confidence interval 1.20 to 4.32, p=0.012). These results show that secondary HPTH due to hypovitaminosis D is a frequent disorder in hospitalized elderly, strongly correlated with the functional status, irrespective of sex and place of residence.

    ABSTRACT: To evaluate the feasibility and predictors of success of home-based rehabilitation (HBR) in older adults after hip fracture. Prospective inception cohort study with 12 months of follow-up. Acute and subacute care with follow-up in a community setting in Italy. Community-dwelling older adults (N=199) aged 70 years or older, discharged from an acute orthopedic unit after repair of a nontraumatic proximal femoral fracture. Patients' choice of pursuing HBR or institutional-based rehabilitation (IBR). Proportion of subjects discharged home for rehabilitation. Rates of institutionalization assessed at 3, 6, and 12 months postdischarge. Mean changes of the Barthel Index from baseline and proportion of subjects who regained their prefracture levels of function at the time of follow-up in the 2 intervention groups (HBR, IBR). Ninety-nine (49.7%) patients chose HBR, and the rest (50.3%) were discharged to a rehabilitation facility. With regard to the baseline characteristics, the 2 patient groups (HBR, IBR) differed with respect to living arrangement (P< or =.001), prefracture functional status in basic (Barthel Index, P=.033; Katz Index, P=.041) and instrumental activities of daily living (IADLs) (P=.041), and occurrence of delirium (P=.022). During the follow-up, the number of subjects institutionalized at 3, 6, and 12 months was 52, 26, and 22, respectively. In the multiple logistic regression model, the only significant variable affecting the choice of IBR at discharge was the absence of relatives at home (odds ratio [OR], 6.7; 95% confidence interval [CI], 3.33-13.46; P< or =.001), whereas a prefracture functional impairment in more than 3 IADLs (at 12 mo: OR=3.99; 95% CI, 1.57-10.18; P=.004), the absence of relatives at home (at 12 mo: OR=8.81; 95% CI, 2.47-31.46; P=.001), and delay to surgery longer than 3 days (at 12 mo: OR=5.51; 95% CI, 1.28-23.81; P=.022) resulted in significant risk factors for long-term institutionalization. Compared with subjects who received traditional rehabilitation, those discharged home showed--after controlling for prefracture Barthel Index score, IADLs, cognitive status and age--a slightly lower functional decline and a higher rate of recovery during the follow-up (mean change in Barthel Index score +/- standard deviation at 12 mo: HBR, -11.2+/-24.7 vs IBR, -23.7+/-28.5; P=.015). In an unselected population of hip-fractured older adults previously living in the community, HBR seems to be a feasible alternative to IBR in those subjects living with relatives.

    ABSTRACT: Whether elderly patients with asymptomatic or minimally symptomatic primary hyperparathyroidism (PHPT) should be treated or not is still under debate. Several literature reports have shown improvements in terms of bone density and physical and mental well-being after surgical resolution of PHPT. Here, we present the case of a 93-year-old hypertensive woman, who had suffered for one year from cognitive impairment, accompanied during the last month by behavioral alterations (and polyuria and polydipsia), which resulted in sopor leading to hospitalization. A CT brain scan evidenced cortical atrophy and cerebrovascular disease, and biochemical analyses were remarkable for hypercalcemia (11.4-12.6 mg/dL, corrected for albumin levels) associated with increased parathormone levels (95.4-100.6 pg/mL). A diagnosis of PHPT was established. Densitometry evaluation of radius showed osteopenia. Withdrawal of psycho-therapy drugs and thiazidic, together with i.v. saline hydration and loop diuretics, significantly improved the patient's mental state and resolved behavioral alterations. As the patient and her relatives refused the surgical option, and the clinical situation improved after medical normalization of calcium levels, PHPT was managed conservatively, and calcium levels were maintained within the normal range through i.v. administration of zoledronate at 8-week intervals. Our case highlights the importance of considering hypercalcemia as the cause of onset of behavioral alterations and worsening of mental condition in elderly patients with cognitive decline. Therapy with bisphosphonates in patients with PHPT who are unfit for or refuse surgery seems advisable, but needs further study.

    ABSTRACT: Thyroid storm is an uncommon but life-threatening manifestation of hyperthyroidism which, unless appropriately treated by combined therapy, causes 30-60% of deaths in hospitalized patients. Mental deterioration leading to apathy and eventually coma is a rare clinical presentation of this pathology, frequently observed in the elderly. We present the case of a 77-year-old hypertensive woman who was hospitalized for fast onset of coma, probably due to the unusual combination of a hypernatremic hyperosmolar state and an unexpected thyroid storm (TS). Although not definitely ascertained, the possible etiology was the hyperthyroid phase of chronic autoimmune thyreopathy (Hashitoxicosis). Notably, the significant adjunctive role of thyroid hyperfunction in the pathogenesis of coma was confirmed by the fact that, although metabolic abnormalities were overcome, complete and satisfactory recovery of the patient's mental and physical condition occurred only with normalization of thyroid hormones by antithyroid treatment. Our case highlights the importance of properly evaluating thyroid function in elderly patients who show a sudden progressive impairment in their mental condition, for early detection of potentially fatal conditions such as thyroid storm or myxedematous coma.
