In the present study we used a well-characterised model of murine lupus, the female NZB/W hybrid, to study the possible involvement of neuropeptides in the pathogenesis of systemic lupus erythematosus (SLE). Analysis of neuropeptides with a possible role in inflammation showed that substance P (SP) calcitonin gene-related peptide (CGRP) and neuropeptide Y (NPY) are present in increased quantities in the inflamed kidneys of SLE mice, confirming their involvement in local inflammation, while there is a general reduction in the peptide concentrations in the lymphoid organs of lupus mice, except for NPY. Our results suggest that the altered neuropeptide concentrations observed in the SLE lymphoid organs may be partly responsible for the altered immune response and contribute to the development of autoimmune diseases.

It has been reported that more than 50% of lupus patients show various forms of neurological deficits including impaired cognitive functions and psychiatric disorders. Using an animal model of lupus we investigated the production of neuropeptides in the brain of NZB/W F1 female hybrid mice and its parental strain NZB and NZW. Our results indicate that the alteration in learning and memory described in lupus mice are paralleled by a decrease in calcitonin gene-related peptide, substance P and neuropeptide Y (NPY) levels in the hippocampus and a significant decrease of NPY in the cortex. These findings are interesting in the light of previously reported results suggesting that these neuropeptides can play an important role in cognitive functions. We also observed a decrease of NPY and vasoactive intestinal polypeptide levels in the hypothalamus of lupus prone mice and these changes may be related to the disregulation of the hypothalamus-pituitary-adrenal axis observed in lupus prone mice.

Treatment of giant cell lesions of the jaws is currently a subject of acute interest in the maxillofacial community. Based on their presumptive histological and biological similarities to both the "brown tumors" of hyperparathyroidism as well as proliferative vascular lesions, both calcitonin and interferon alpha administration have been attempted in patients suffering from these lesions. We present a case report of one young female in which both of these treatment modalities were instituted. We also discuss a rarely reported complication consisting of drug-induced lupus erythematosis and pancreatitis secondary to interferon alpha use.

The coexistence of systemic lupus Erythematosus (SLE) and multiple myeloma (MM) is uncommon and the pathogenetic mechanisms underlying this association remain unclear. We report the case of a woman who was diagnosed with SLE in 1993 aged 57, then developing IgA lambda type MM in the IIB clinical stage 7 years later. The SLE was treated successfully with methylprednisolone and chloroquine, and low dose maintenance steroid was continued with bisphosphonate protection until December 1994 when she suffered multiple vertebral fractures. She continued to receive 4 mg alternate day methylprednisolone and calcitonin until she decided to discontinue her own treatment 2 years later. In 2000, while still in stable SLE remission, she was diagnosed with MM. Protein electrophoresis revealed the IgA lambda paraprotein (40.5 g/l) and she had a Bence Jones (BJ) proteinuria of the lambda light chain type. Bone marrow trephine biopsy revealed a massive patchy infiltrate of abnormal plasmocytes (70%), while an extensive x-ray skeletal survey did not show any new fractures or osteolysis. The patient was treated according to the VMCP protocol without attaining a plateau phase. There was a similar poor clinical response to second and third line treatments (VAD, Thalidomide, Melphalan, and high dose dexamethasone). After 4 years of refractory disease the patient died from severe bilateral pneumonia. This case is discussed with reference to the literature.

We report a case of a 39-year-old female with active systemic lupus erythematosus who complained of lethargy and weakness with a moderate renal impairment. Hypercalcemia was confirmed by laboratory examination. Her X-ray revealed significant ectopic calcinosis in subcutaneous tissue of bilateral hands, and Tc-99(m) methylene diphosphonate bone scan revealed a remarkably intense uptake of bilateral lungs. She had no evidence suggestive of other diseases related to hypercalcemia such as hyperparathyroidism and malignancy. She had abnormally high serum parathyroid hormone-related protein (PTHrP) which fell to normal after treatment. Glucocorticoid, cyclophosphamide plus calcitonin and etidronate were administered and the patient improved greatly. Literature review demonstrated that lupus-related hypercalcemia with ectopic calcinosis is a rare complication and increased PTHrP is probably one of the main mechanisms. Lung uptake in bone scan may be a special and reliable clue suggestive of hypercalcemia.
