Clinical interest in salmon calcitonin began in 1972 when this peptide was shown to be effective in the treatment of Paget's disease. Salmon calcitonin is more potent than porcine calcitonin, with human calcitonin intermediate in potency. Salmon calcitonin is a highly effective therapeutic agent in the treatment of Paget's disease. During chronic treatment with salmon calcitonin, alkaline phosphatase activity and urinary hydroxyproline excretion decrease on an average of 50% in patients with Paget's disease. Patients may experience a variety of clinical benefits during chronic treatment, including relief of bone pain, a reversal of neurological deficits, stabilization or improvement of hearing loss, and improvement of vascularity of bone. Radiologic healing of osteolytic lesions in particularly striking with calcitonin treatment. Paget's disease patients prefer treatment with salmon calcitonin administered by means of a nasal spray. Salmon calcitonin has an excellent safety profile and produces mild side effects in a small percentage of patients. The most common side effects associated with salmon calcitonin administration are nausea and facial flushing. It is unusual to observe severe side effects. In about 20% of patients, production of antibodies may neutralize the effects of the exogenously administered calcitonin; these patients respond to human calcitonin. At this time salmon calcitonin should still be considered a valuable therapeutic agent in the treatment of Paget's disease, particularly in patients with osteolytic lesions.

Thirty patients with bone metastasis were treated with eel calcitonin (CT) to relieve severe pain from metastatic bone lesions. Patients were two males and twenty-eight females with a mean age of 52.8. CT was administered intramuscularly in twenty-seven patients and intravenously in three. CT was effective on 55.6% of patients to reduce severe bone pain but did not decrease the amount of analgesics in most patients. Serum Ca and P were not changed markedly. As side-effects, two patients complained of nausea and vomiting after administration of CT but they weren't severe. These results indicate that CT is quite useful drug for relief of severe bone pain from metastatic lesions in patients with breast or digestive tract carcinomas.

In a multicentre open trial 530 patients suffering from primary osteoporosis, secondary osteoporosis and Sudeck's disease were enrolled to assess synthetic human calcitonin efficacy on bone pain relief. Spontaneous pain, pain on movement, provoked pain, functional impairment and patient's assessment were recorded. During the first 30 days of treatment, all the parameters significantly improved (p less than 0.01) and the tolerability was satisfactory. Four hundred and ten patients entered a follow-up study, this number gradually decreasing over a 6-month period due to a satisfactory outcome. Efficacy on bone pain remained very high in most of the patients, many of whom continued to improve. These results suggest that synthetic human calcitonin is highly effective on pain and functional impairment in bone disease and is well tolerated.

The efficacy of new calcitonin, the amino analog of eel calcitonin (carboCT) on Sudeck's atrophy of the foot was investigated in 14 patients. CarboCT was administered at the dose of 40 Medical Research Council (MRC) units per day, and the duration of treatment was two to ten months. No adverse effects were noted. Bone pain and local edema decreased associated with improvement of motility. CarboCT induced a slight decrease in plasma calcium, plasma phosphate, and 24-hour urinary calcium excretion. An increase in cAMP/Cr ratio, an index of parathyroid function, was also observed (probably a manifestation of the hypocalcemic effect of calcitonin and secondary parathyroid stimulation). The whole body retention of 99mTc-MDP represents a valuable index of bone turnover, it decreased progressively and significantly on treatment. A dynamic study of local bone uptake of 99mTC-MDP was performed in eight patients. After carboCT therapy, statistically significant decreases in local blood flow, early uptake, and delayed uptake were appreciated in the involved foot. These findings lead to the conclusion that carboCT is effective in the treatment of Sudeck's atrophy.

Vitamin D has complex effects in bone: it stimulates matrix formation and bone maturation but also enhances osteoclastic activity and may influence differentiation of bone cell precursors. Calcitonin inhibits the function of osteoclasts, reducing bone resorption, thus, the combination of vitamin D and calcitonin could result in a positive bone balance. We tested the hypothesis that chronic treatment with high doses of vitamin D (150,000 U/week), moderate doses of salmon calcitonin (120 MRC U/week), and adequate Ca supplementation (1 g/day) could be beneficial in osteoporosis. Thirteen women with postmenopausal osteoporosis received this treatment for 2-6 years (mean 3.5 years). No side effects, hypercalcemia, or hypercalciuria occurred. There was marked reduction in bone pain. The fracture rate in 11 patients with vertebral compression fracture was 240/1,000 patient years, threefold lower than the reported 834 fractures for untreated patients of similar age. Single photon bone densitometry of the radius did not change. Iliac crest bone biopsies obtained at the initiation and conclusion of the study showed a 43% increment in trabecular bone volume (P = 0.0003), without changes of the normal osteoid thickness, surface, and volume. Because single photon densitometry reflects mostly cortical bone, the data suggest that the combination of vitamin D and calcitonin increases trabecular bone mass and prevents the fall of cortical bone mass in osteoporosis. Previous reports suggest that calcitonin alone or with small doses of vitamin D increased bone mass for about 2 years. The present study suggests a prolonged beneficial effect of the combination of high doses of vitamin D with rather moderate (less than 150 MRC U/week) doses of calcitonin in postmenopausal osteoporosis.

Cancer patients may experience acute or chronic pain caused by tumor infiltration of pain-sensitive structures or related to surgery, radiation, and chemotherapy. Acute bone pain, with or without associated neurologic deficits resulting from tumor metastasis to bone and contiguous neural structures (e.g., large peripheral nerve trunks or the spinal cord), is a common cause of intractable pain in cancer patients. Most often, treatment of bone pain involves the concomitant use of focal radiation therapy and analgesic drugs, especially steroids, nonsteroidal anti-inflammatory drugs (usually in combination with opioids), and adjuvant analgesic agents such as levodopa and calcitonin. However, pharmacologic therapy is not always efficacious and may have significant side effects. Less commonly, invasive therapies, such as resection of vertebral body tumor with spinal reconstruction or pituitary ablation and intraventricular opioid administration (for diffuse bone pain), are offered. In this article I discuss current approaches to the management of pain in cancer patients, emphasizing current hypotheses on the pathogenesis of bone pain and the rationale for its pharmacologic treatment.

Forty-seven patients of advanced urogenital carcinoma with bone metastasis were treated with eel calcitonin (CT) to relieve severe pain from metastatic bone lesions. Patients were 45 males and 2 females with a mean age of 72.9. CT was administered intravenously at a daily dose of 160 units for 10 days. The efficacy of CT on relief of pain was estimated using a mark sheets filled by each patient and his or her doctor. And also the amount of analgesics given to patients before and after the administration of CT were checked. CT was effective on 77% of patients to reduce severe bone pain, especially on osteoblastic lesions metastasized from prostatic carcinoma. CT administration decreased the amount of analgesics in 37% of the cases. As toxicity, nausea and vomiting which stopped the CT administration were observed in only one From these results, we conclude that CT is quite useful drug for relief of severe bone pain from metastatic lesions in patients with urogenital carcinoma.

The pathogenesis, clinical features, indications for therapy, and current pharamacologic management of Paget's disease are reviewed. Paget's disease is a bone disorder of unknown etiology primarily affecting the elderly. Overactive bone resorption leads to the accelerated formation of disorganized, weak bone. Pain and fractures are common clinical features. Neurologic, cardiovascular, metabolic, and neoplastic complications are also reported. Because most patients are asymptomatic, the disease is often detected during routine roentgenography or laboratory tests. Primary indications for pharmacologic intervention include bone pain, neural compression, immobilization hypercalcemia or hypercalciuria, cardiac failure, and orthopedic surgery. Recurrent or non-healing fractures and rapidly progressing complications are additional indications. Drugs used in the management of Paget's disease include calcitonin, etidronate disodium, and plicamycin. Although these agents are efficacious, each has disadvantages. Clinical resistance to animal calcitonins may develop, and the cost of therapy may be prohibitive. Etidronate may induce ostemalacia. The use of plicamycin is limited by potentially severe toxicities. Dichloromethylene and aminohydroxypropylidene are promising diphosphonate compounds but are still investigational In those patients who are unresponsive to single-agent regimens, combination therapy may prove effective. Although many patients with Paget's disease do not require pharmacologic therapy, calcitonin and etidronate are the agents of choice when it is indicated.

Calcitonin (CT) constitutes one of the major choices for the pharmacologic treatment of postmenopausal and senile osteoporosis. In postmenopausal osteoporosis, CT, analogous to estrogens, determines increase of bone mass, improvement of intestinal calcium absorption and a positivization of calcium balance. Patients treated with CT can also benefit from the analgesic effect of the hormone. Unlike estrogens, these beneficial effects of CT occur with minimal risk and require no routine gynecological monitoring. In addition, CT is completely devoid of toxicity. The only limitations to the use of CT are linked to the frequent parenteral injections and the occurrence of side effects. These limitations can now be overcome by the availability of the new nasal spray preparation, which has been developed for synthetic salmon calcitonin (sCT). The introduction of this new form increases the patients' compliance, and the different pharmacokinetic curtails the side effects, compared to the parenteral administration. At present, one-year controlled studies have been reported, showing a beneficial effect of sCT on bone mass in patients with established osteoporosis. Also, shorter studies demonstrate the analgesic activity of sCT treatment in patients with vertebral crush fractures and bone pain. The improvement in the patients' compliance and the reduction of side effects allow this new CT preparation to be used in the prevention of postmenopausal osteoporosis.

Paget's disease of bone is often discovered incidentally, but can have extensive metabolic and local mechanical complications. Treatment is not required for all patients and should only be undertaken for certain indications, and with a clear understanding of the three types of drugs available. Bone pain unmanageable with analgesics and pathologic fractures are the most common indications, while neurologic symptoms, hypercalcemia and congestive heart failure are less frequent ones. Calcitonin or mithramycin is used for the more urgent indications, and calcitonin or the diphosphonate, etidronate sodium (EHDP), for the more chronic ones. The drugs are generally efficacious and well tolerated.
