Cinacalcet in secondary hyperparathyroidism
Introduction: Approximately ten percent of renal transplant patients maintain persistent high blood levels of Calcium. Persistent secondary hyperparathyroidism is the most frequent cause of hypercalcemia. Recently Cinacalcet a second generation calcimimetic agent ; has shown effectiveness in the treatment of secondary hyperparathyroidism in patients on dialysis with beneficial effect on calcemia. There are no extended experience with Cinacalcet in renal transplanted patients. We presented our experience with Cinacalcet in renal transplanted patients with persistent hipercalcemia and secondary hyperparathyroidism Methods: 10 patients were prospectively included 8 women and 2 men ; , with mean age of 59.5 2.4 years and time after renal transplant of 70.16.5 months. The immunosuppressive regimen consisted of: Cyclosporin 6 patients, Tacrolimus 3 patients, Rapamycin 1 patient. The inclusion criteria was persistent hypercalcemia 10.5 mg dl ; more than six months after surgery. Treatment with Cinacalcet was initiate at 30 mg day. Basal and monthly blood levels of Creatinine, Ca, P, alkaline phosphatase, Mg, acid-base balance, PTHi, metabolites of vitamin D and immunossuppresion were determinated and calciuria and phosphaturia. The follow up period was 9 months. Results: Renal function shown no significant changes during the follo-up period Basal Creatinina 1.60.4 mg dl, at 9 months 1.30.5 mg dL p ns ; . The basal serum calcium was 11.70.4 mg dl with a rapid and persistent reduction during the follow-up and at 9 months the serum calcium was 10.10.4 mg dl p 0.001 ; The basal phosphorus had a tendency to increase with no significance Basal 2.80.3 mg dl, at 9 month 30.4 p ns ; . The basal PTHi.

Comment Separately recommending the sub-group of patients contraindicated for vitamin D where cinacalcet is their only available treatment option. Vitamin D analogues can be effective for suppressing PTH but it also acts on the intestine to promote intestinal absorption of Ca and P. Hence, persistent hyperphosphataemia or hypercalcaemia is often aggravated by vitamin D therapy. Both the acute clinical sequelae of hypercalcaemia nausea, vomiting, mental confusion, shortening of the QT interval, and cardiac arrhythmias ; and especially the chronic implications of long term hypercalcaemia limit the use of vitamin D in patients with hypercalcaemia. Consequently the prescribing information of all licensed vitamin D sterols calcitriol, 1-alfacalcidol, and paricalcitriol ; contain wording that contraindicates the use of vitamin D in the event of hypercalcaemia. Accordingly, treatment guidelines for the treatment of secondary hyperparathyroidism recommend that the dose of vitamin D is reduced or stopped when serum Ca is above 2.5 mmol L REF ; . In these situations patients and clinicians have no other treatment options to control PTH other than cinacalcet. Cinacalcet is the first treatment that has demonstrated its ability to reduce iPTH, Ca and P. In conclusion, Amgen request the Appraisal Committee consider extending the group of patients recommended for treatment to include those who are contraindicated for vitamin D.

Pain disorder. Administration of paroxetine 1020 mg day reduced muscle tension and pain in the lower jaw in about 3 weeks. The intensity of pain and discomfort was evaluated using a visual analog scale VAS ; and distance of opening mouth. The mouth-opening movements were registered by the distance between incisal edges. At rest, her mouth opening improved from 27 mm to mm, and her VAS score decreased from 100 mm to 30 mm. Case 2. Ms. B, a 24-year-old woman, developed a sense of discomfort that was disabling and pain in the temporomandibular region on yawning around the age of 20 years. She was able to open her mouth less each day. At the age of 22 years, she consulted a dental clinic different from the clinic in case 1 ; . Ms. B's mouth opening was improved by splint treatment from 8 mm to mm, and her pain almost disappeared. At the age of 24 years, the pain began again. She was referred to our psychiatric department with comorbid mental uneasiness. She complained of anxiety over worsening of TMD and her future. Her SDS score was 48 points. She was diagnosed with DSM-IV pain disorder. Administration of paroxetine 1020 mg day reduced tension and pain of the jaw in about 2 weeks. The distance of her mouth opening improved from 19 mm to mm, and her VAS score decreased from 100 mm to 30 mm. TMD patients may have symptoms that are acute and resolve without therapy or with only limited, conservative therapy. For chronic TMD, drug therapy with analgesics is usually indicated. However, in some cases, analgesics are ineffective. Antidepressants have an antinociceptive analgesic ; effect on chronic pain independent of the antidepressant effect.4 In the past, TCAs were considered the gold standard in the treatment of different kinds of neuropathic pain, as studies showed their superiority compared to placebo or other available drugs.2 There have been case studies1, 5 demonstrating that TCAs were sufficient to significantly reduce pain and discomfort due to chronic TMD. However, with TCA treatment, a large number of side effects are observed, which, although not life-threatening, significantly affect the patient's quality of life, causing a limitation of tolerability. Common side effects include dry mouth, sedation, memory impairment, constipation, and orthostatic hypotension. Patients who are intolerant or resistant to TCAs may be treated with SSRIs.6 Although a complex mechanism underlies the antinociceptive effects of antidepressants, it is suggested that SSRI-induced antinociception involves both central opioid and serotonergic pathways.7 Until now, there have been no case reports describing the beneficial effects of SSRIs for TMD patients. We report 2 patients with chronic or recurrent pain due to long-term TMD who were treated with an SSRI. These patients were diagnosed with TMD and received standard dental therapy along with analgesics without significant efficacy. Administration of the SSRI paroxetine remarkably reduced the persistent and unpleasant pain of TMD within a short period without side effects. SSRIs can be beneficial in reducing TMD pain complaints as one method of dental therapy. Dentists and physicians, including psychiatrists, should have an understanding of the increasing utilization of SSRIs for managing chronic TMD pain. TMD develops from multiple factors, causing long-term pain and interfering with the patient's daily life. The biopsychosocial conceptualization of the pain experience illustrates the close connection between pain and psychosocial factors. Common emotional problems include anxiety, depression, and anger. It is important to recognize and treat psychiatric or emotional concerns as well as physical symptoms.8 and cisplatin.

Sir, We read with great interest the article by Henley et al. [1] showing that cinacalcet could not prevent vascular calcifications induced by calcitriol in uraemic rats and would like to make the following comments: 1 ; This inefficiency might be explained by the stability of the calcium phosphate Ca PO4 ; product because the decrease in serum calcium SCa ; was compensated by an increase in SPO4. Indeed at the end of the study, the mean SPO4 of the three measurements before and 424 hours after the dose ; was 1.4 mg dl 29% ; higher when cinacalcet was compared with vehicle and 1.9 mg dl 23% ; higher when cinacalcet calcitriol was compared with calcitriol alone. 2 ; This hyperphosphataemic effect of cinacalcet in uraemic rats has already been reported with the first generation calcimimetic NPS558 [2] and is in complete agreement with the mirror image of the trade off theory of secondary hyperparathyroidism in uraemia developed by Slatopolsky and Bricker [3]: hyperparathyroidism is the price the organism pays to eliminate phosphate retention induced by the reduction of its glomerular filtration. 3 ; These experimental results do not contradict the decrease in SPO4 reported in dialysis patients receiving cinacalcet [4]. This decrease was, however, mild 7% ; when 1aOH vitamin D was stable and almost twice smaller when 1aOH vitamin D was increased [5]. This difference can probably be explained by the fact that when vitamin D is increased to correct cinacalcetinduced hypocalcaemia, PO4 absorption is increased, whereas when CaCO3 is used instead, this latter complexes phosphate in the gut and decreases SPO4. 4 ; These deleterious effects of calcitriol in uraemic rats and patients contrast with beneficial effects of an increased oral calcium-load: In uraemic rats, high calcium diet alone has been shown to decrease mortality in association with a lower SPO4 and a decrease in proteinuria and blood pressure associated with a lower expression of the AT1-receptor of angiotensin II [6]. In uraemic mice with ApoE gene deletion-induced atherosclerosis, high calcium is also quite effective in decreasing aortic calcifications [7]. In dialysis patients, never exposed to aluminium, high CaCO3 dose 69 g per day taken as phosphate binder ie at 2.43.6 g of elemental calcium ; , without 1aOH vitamin D, but with calcidiol repletion and a dialysate calcium concentration of 1.5 mmol l not inducing negative per-dialytic calcium balance ; , a good control of hyperparathyroidism can be obtained usual PTH 220 pg ml in two third of the patients ; without hypercalcaemia nor hyperphosphoraemia. This results in a good preservation of bone mineral density BMD ; , especially of the cortical bone, without any inverse correlation between BMD and vascular calcification, as has been reported in dialysis patients using 1aOHvitamin D [8]. The only independent risk factors for vascular calcifications were age and duration on dialysis, whereas phosphocalcic, plasmatic and therapeutical parameters were in no way correlated [9].

Ing transportation-related pollution, and boosting our region's economy. 50% of the electricity used by the Mitchell Center effectively will be fossil fuel-free for at least the first two years of operation, utilizing a contract for the "environmental attributes" of electricity generated by wind turbines. Water-efficient plumbing fixtures used throughout the Mitchell Center will permit the facility to meet its needs using 26% less water. Almost 90% of the constructionrelated wastes were recycled or reused, resulting in cleaner air for our community as less waste is processed in local incinerators. The John Mitchell Center, built in 1965, is named after USM professor emeritus John Mitchell of Gorham. Mitchell was instrumental in the creation of what is now USM's School of Applied Science, Engineering, and Technology, and during his career, he was recognized as a national leader in the field of industrial education.
Econdary hyperparathyroidism is common in patients with chronic kidney disease, affecting most of those who are receiving hemodialysis.1, 2 The disorder is characterized by persistently elevated levels of parathyroid hormone and complicated by important disturbances in mineral metabolism.3 Bone disease is the most widely recognized consequence of secondary hyperparathyroidism.4 Several reports indicate, however, that alterations in calcium and phosphorus metabolism, as a result of either secondary hyperparathyroidism or the therapeutic measures used to manage it, contribute to soft-tissue and vascular calcification, cardiovascular disease, and the risk of death.5-10 Episodes of hypercalcemia and hyperphosphatemia are often aggravated by the use of large doses of calcium as a phosphate-binding agent, particularly in combination with vitamin D sterols, which increase the absorption of calcium and phosphorus.10-13 There is thus considerable interest in identifying therapeutic alternatives that control secondary hyperparathyroidism while limiting these side effects. The calcium-sensing receptor regulates the secretion of parathyroid hormone.14 Calcimimetic agents increase the sensitivity of the calcium-sensing receptor to extracellular calcium ions, 15, 16 inhibit the release of parathyroid hormone, and lower parathyroid hormone levels within a few hours after administration.17-19 This mechanism of action differs fundamentally from that of vitamin D sterols, which diminish the transcription of the parathyroid hormone gene and hormone synthesis over a period of many hours or several days.20 Results of previous small clinical trials indicate that the calcimimetic agent cinacalcet hydrochloride not only reduces parathyroid hormone levels but also lowers serum calcium and phosphorus levels in patients with secondary hyperparathyroidism.21-23 We report the combined results of two large phase 3 clinical trials of identical design to determine the safety and effectiveness of cinacalcet for treating secondary hyperparathyroidism in patients undergoing hemodialysis and clorazepate.
