In a prospective clinical study, with the patient as its own control, we selected patients with stage III multiple myeloma. We treated them monthly with intravenous (i.v.) Disodic Pamidronate: 90 mg in 2 to 21 cycles. Four patients died during the study. The remaining 13 patients presented reduced bone resorption urinary markers (D-Pyr mainly) as well as urinary calcium (bone turnover reduction). Both effects (metabolic interchange reduction and calcium variation) did not show a direct relationship, being the 1st magnitude proportional to the baseline level and the 2nd independent from it. We noted pain reduction (VAS: visual analogs scale), low analgesic consumption, and the absence of future skeletal problems. The treatment tolerance was good. All these factors contribute to justify the welfare of the patient demonstrated by ECOG (Eastern Cooperative Oncology Group), not only improving the average results but also extending this improvement to future results. Our observation suggests that under strict procedures, this treatment could be very adequate in patients with advanced multiple myeloma independent of the state of the disease at the beginning of the study.

Over the past 20 years, orally administered biphosphonates have been used extensively in the management of a number of common skeletal disorders of different etiology. Recently, in clinical practice, in a number of cases in whom oral therapy is insufficient or contraindicated, intravenous administration of pamidronate presents an alternative therapeutic option. In order to investigate the clinical and radiological effects of cyclic intravenous pamidronate administration in children with osteogenesis imperfecta, a prospective open study of pamidronate treatment was undertaken in a cohort of eight bed-bounded (3.6-13.8 years) patients with severe osteoporosis and vertebral deformities. Pamidronate was administered at a dose of 0.5 mg/kg/ day for three days. Tri-monthly cyclic intravenous infusions were performed over-one year. Bone density, verebral corpus heights, estimated volumetric bone density and biochemical measurements were analyzed. Side effects of the therapy were determined via questionnaire. Significant reductions in the number of bone fractures and pain were observed in all patients. Ambulation scores were significantly altered and seven of eight patients became independent. Serum alkaline phosphatase levels decreased significantly. Lumbar X-ray and densitometry showed a striking improvement by the end of the treatment period. Even spaced dense lines corresponding to infusion periods were observed on roentgenograms of the radio-ulnar region. Pubertal progression and growth velocity were not affected inversely during therapy. Although we did not observe any severe side effect, one patient's blood urea nitrogen level was altered slightly. In conclusion, one year cyclical pamidronate treatment seems to be effective and safe in improving bone mineralization and in reducing fracture incidence in severe osteoporosis.

Pediatric nephrology and rheumatology patients with steroid-induced osteopenia are at risk of skeletal fracture. Bisphosphonate therapy has not been routinely advocated as a primary or secondary intervention for steroid-associated fractures in this population. This case control study evaluates the role of pamidronate therapy as a secondary fracture intervention. Children with symptomatic pathological fractures of the axial spine or ribs were treated with pamidronate 1 mg/kg/dose (n=17) IV at 60-day intervals for 1 yr (n=15) or 2 yr (n=2). Bone mineral density of L1-L4 (BMD) was assessed prior to treatment and at six-month intervals, and compared to 17 disease-age-gender-steroid dose-matched control patients. Alkaline phosphatase, calcium, phosphate, PTH, renal biochemistry, and 24-hr urine collections for CrCl, N-telopeptide/creatinine ratio, phosphate excretion, and calcium excretion were obtained every two months in the pamidronate population. Pamidronate caused a first exposure transient flu-like illness lasting <24 h in three patients and one patient had a new pathological fracture. No adverse events of hypocalcemia, allergic reaction or thrombophlebitis were noted. All patients reported improvement of skeletal pain. Despite ongoing steroid treatment, pamidronate significantly increased L1-L4 BMD Z-scores (mean+/-SE) relative to baseline (pamidronate vs control: 0-6 months: 0.27+/-0.14 vs -0.82+/-0.31; 0-12 months: 0.63+/-0.17 vs -0.46+/-0.27; 0-18 months: 0.55+/-0.32 vs 0.17+/-0.27; 0-24 months: 0.15+/-0.21 vs -0.23+/-0.22; 0-30 or 36 months: 0.77+/-0.71 vs -0.68+/-0.25) with repeated measures ANOVA assessment (F=11.27, p=0.0057). This study supports the safety and efficacy of pamidronate in steroid-induced fractures in pediatric nephrology and rheumatology patients.

The objective of this study is to evaluate the effectiveness of pamidronate for the treatment of chronic neuropathic pain refractory to previous management. Intravenous pamidronate (60 mg/day for 3 days) was administered to 2 adolescents with neuropathic pain refractory to previous multidisciplinary treatments. Pain intensity, functional improvement, and adverse effects were evaluated. There were no significant reductions in pain intensity or improvements in function initially or at follow-up at 1 week, 1 month and 4 months. Minor side effects included myalgia and skeletal pain that were relieved by acetaminophen. There was no long-term morbidity. In contrast to recent positive reports in adults, pamidronate was not effective in decreasing pain or improving function in 2 adolescents with chronic neuropathic pain. Pamidronate may be effective only when pain is accompanied by abnormal bone density. Future trials should include scans to document bone density pretherapy and posttherapy.

The main objectives of medical therapy in ankylosing spondylitis (AS) are to relieve pain, stiffness and fatigue and to prevent structural damage. The Assessment in Ankylosing Spondylitis Working Group has proposed different domains with specific instruments to assess the efficacy of therapeutic agents classified as symptom-modifying and disease-controlling antirheumatic drugs. Non-steroidal antiinflammatory drugs (NSAIDs) are still the first-line treatment in the management of AS, and they are effective in controlling symptoms such as pain and stiffness and maintaining mobility in many patients. A recent randomized trial suggested that the progression of radiological damage occurs less on continuous use of celecoxib compared with on-demand use. If such findings were confirmed by other studies, the therapeutic value of NSAIDs in AS may extend beyond symptom control. However, for each individual patient, the expected advantages of treatment with NSAIDs should be weighted against any possible gastrointestinal and cardiovascular disadvantages. Disease-modifying antirheumatic drugs (DMARDs) are widely used for second-line therapy in AS, but the evidence for their efficacy is poor. The term 'DMARD' has been borrowed from rheumatoid arthritis, and none of the DMARDs have been shown to prevent or significantly decrease the rate of progression of structural damage which is required to be qualified as a disease-controlling antirheumatic drug for AS. Sulphasalazine is the most extensively studied DMARD and studies suggest some degree of clinical benefit confined to peripheral joint involvement, but no evidence of benefit in axial disease. Methotrexate, which is the gold standard DMARD in rheumatoid arthritis, does not seem to have a substantial therapeutic effect in AS on axial or peripheral joint involvement. Leflunomide appears to exert little beneficial effect, if any, even on peripheral joint involvement. There is also good evidence that local therapy with corticosteroids is effective and may be used in selected patients. Oral corticosteroids may be somewhat effective in relieving the symptoms of AS, but this has not been formally studied. Small studies have reported favourable results with intravenous methylprednisolone pulse therapy, but the effect is temporary. Pamidronate and thalidomide have been used in some preliminary trials but need further studies to assess their potential role in treating AS patients resistant or intolerant to other forms of treatment. Treatment with tumour necrosis factor blockers is not discussed in this review.

We report a case of a healthy, young, female soccer player who developed progressive pain in her right hip. A bone cystic lesion was found in the right femoral neck and proximal femur. The lesion was considered a benign bone cyst and the patient was treated with injections of autologous bone marrow and grafting into the femoral neck. However, the cystic lesion did not heal. Subsequently, the patient fell and developed a fracture of the femoral neck that required internal fixation. The bone biopsy showed characteristic histologic features of fibrous dysplasia. A bone scan showed other areas of suspected dysplasia. Pamidronate therapy was given, and a reduction of the increased uptake was seen on bone scans. Fibrous dysplasia must be considered in the differential diagnosis of any cystic bone lesion.

Bisphosphonates offer a significant improvement in the quality of life for cancer patients; these potent inhibitors of bone resorption have been shown to markedly reduce the morbidity frequently resulting from bone metastases. Despite the success of bisphosphonates as therapeutic agents, however, toxicity in the form of osteonecrosis of the jaw (ONJ) is a rare complication whose incidence rate has climbed in recent years. ONJ is defined as an unexpected development of necrotic bone in the oral cavity, and is commonly associated with administration of the bisphosphonates Pamidronate and Zoledronate. Clinical features include local pain, soft-tissue swelling, and/or loose teeth; ONJ is also often correlated with previous dental procedures, such as tooth extractions, during biphosphonate therapy. Although additional risk factors-such as corticosteroids, chemotherapy, radiotherapy, trauma or infection-exhibit etiological associations with ONJ, the real pathobiology has not yet been fully elucidated. Here we report our findings on all 2005 OJN cases presented at our institution resulting from bone metastatic prostate cancer treated with zoledronic acid. The incidence of ONJ is nearly 3% (3 out of 104) in these patients.

Many solid tumors metastasize to bone, leading to debilitating skeletal complications such as intractable bone pain and pathologic fractures. Patients who experience a skeletal-related event (SRE) are at higher risk for subsequent events. After an SRE such as a pathologic fracture, spinal cord compression, or the requirement for orthopedic surgery or palliative radiation therapy, a patient's quality of life and functional independence could decline substantially. Prevention or delay of skeletal complications provides clinical benefit to patients with bone metastases secondary to solid tumors. Treatment for the prevention of the first SRE might substantially improve patients' quality of life, functional independence, and pain throughout the course of their disease. Bisphosphonates have shown a palliative benefit in this setting. In particular, zoledronic acid is the only bisphosphonate that has provided benefits for patients with bone metastases secondary to a broad range of solid tumors. Among patients with metastatic breast or prostate cancer, zoledronic acid has demonstrated significant reductions in pain and skeletal morbidity compared with placebo. Zoledronic acid has also shown significant reductions in skeletal morbidity in patients with lung cancer or other solid tumors compared with placebo. Pamidronate, oral clodronate, and ibandronate compared with placebo have each shown significant benefits in reductions of pain and skeletal complications for patients with metastatic breast cancer. Further improvements in the management of skeletal health in patients with malignant bone disease could be achieved through ongoing bisphosphonate investigations to optimize dose, timing, and duration of treatment.

Pamidronate, along with other bisphosphonates, has been used for treatment of bone pain secondary to malignant involvement or metastatic disease for years. Some data, however, have also accumulated on the utility of pamidronate in a variety of benign conditions frequently handled by rheumatologists. This study aims to review the available published data regarding the potential use of pamidronate in rheumatology practice. Methods include the review of relevant articles retrieved by a PUBMED search utilizing the index term "pamidronate". All available randomized control trials, open trials, and case series, as well as properly reported case studies evaluating usage of pamidronate in rheumatic disorders, have been included in the literature review. The efficacy of pamidronate in patients with spondyloarthropathies; synovitis, acne, pustulosis, hyperostosis, and osteitis syndrome; hypertrophic osteoarthropathy; osteoporotic vertebral fractures; chronic back pain due to disk disease or spinal stenosis; Charcot arthropathy; transient osteoporosis; and complex regional pain syndrome-I, has been demonstrated in more than 40 reports, the majority of which, however, were not controlled studies. In some of reviewed conditions, aside from providing analgesic relief, pamidronate may also have disease-modifying properties. While used in different doses in a variety of rheumatic disorders, pamidronate was generally reported to be well tolerated with an overall good safety profile. Pamidronate may represent an effective and safe choice for a spectrum of rheumatic patients, suffering from intractable musculoskeletal pain, unresponsive to traditionally recommended therapies. Large randomized, controlled studies examining the efficacy of pamidronate in the rheumatic conditions are urgently needed.

A 14-year-old girl with juvenile dermatomyositis developed extensive and debilitating calcinosis, unresponsive to colchicine, while muscle involvement subsided. Pamidronate (2mg/kg/year) produced dramatic improvement of pain and function within 2 months and calcinosis had completely resolved by 2 years. No new calcifications have been noted with a 5-year follow-up.
