A 67-year-old man presented with nephrotic syndrome and polymyalgia rheumatica. A renal biopsy revealed minimal-change nephropathy. The proteinuria and rheumatologic findings responded to prednisone therapy. The patient presented three months later with biliary tract obstruction secondary to pancreatic adenocarcinoma metastatic to the liver. The glomerulopathy and polymyalgia rheumatica in this case seemed to be components of the paraneoplastic syndrome. The response of both entities to prednisone therapy supports the hypothesis that they are caused by derangements in cell-mediated immunity. The fact that the tumor progressed despite resolution of the nephrosis and polymyalgia rheumatica suggests that cell-mediated immunity in general is altered by the tumor and not that the carcinoma liberates a factor that directly damages the kidney.

We describe the clinical case of 80 years, caucasian woman, with personal history of osteoporosis and chronic normochromic normocytic anemia (NN). She had a three month history of myalgias of the girdle, stiffness in the morning, exceeding 1 hour, associated with inflammatory arthralgia of the small joints of hands and feet. Complementary exams showed normocytic normochromic anemia with Hg 9.8 g/dL; ESR 44 mm/h; CRP 7 mg/dL. Given the profile suggestive of Polymyalgia Rheumatica started prednisolone 10 mg/day with favorable clinical response. Four months after treatment she started paresthesias of right hand and foot, polaquiuria, petequial lesions in lower limbs and inability to walk; there was worsening of anemia and elevation of the biological parameters of inflammation, beginning of renal insufficiency with creatinine clearance 22 ml/min, proteinuria and eritrocituria. Renal biopsy was compatible with Wegener's granulomatosis/microscopic poliangeite. Vasculitis is a rare disease of the elderly and its clinical presentation is varied. The arteritis of giant cells and Polymyalgia Rheumatica are more common in the elderly. It is not often Polymyalgia-like presentation in cases of Wegener's granulomatosis/microscopic polyangitis.

Polymyalgia rheumatica (PMR) is a common chronic inflammatory disorder affecting patients over the age of 50. Renal involvement in PMR is extremely rare and very few cases of AA amyloidosis secondary to PMR have been described in literature. We present a case of a patient with history PMR who developed nephrotic range proteinuria and rapidly deteriorating renal function secondary to AA amyloidosis within 18 months of the onset of symptoms of PMR. This case reinforces the association of PMR with secondary AA amyloidosis and highlights the importance of monitoring renal function in patients with PMR.

A 70-year-old man complained of muscle pain in his neck, shoulders and pelvic girdle. Proteinuria and hematuria subsequently developed. Blood analysis showed increased acute phase reactants. The histology of renal biopsy showed diffuse endocapillary proliferative glomerulonephritis. There were no signs of autoimmune diseases, malignancies and bacterial or viral infections. His extrarenal symptoms and the results of blood analysis fulfilled three different criteria of polymyalgia rheumatica (PMR). Therefore, diffuse endocapillary proliferative glomerulonephritis associated with PMR was diagnosed. After low-dose prednisolone (10 mg/day) treatment, the muscle pain disappeared, acute phase reactants decreased and hematuria and proteinuria improved. The renal complication of PMR is rare but important to be considered early in the right clinical context.

The best approach to treatment of de-novo rheumatoid arthritis in solid organ transplant recipients on typical immunosuppression is not well established. The use of biologics targeting specific cell types, cytokines, and immunological pathways has been gaining interest in the treatment of both, auto- and alloimmunity. We present a case of de-novo rheumatoid arthritis in a kidney transplant recipient 10 years post-transplant while receiving cyclosporine, mycophenolate mofetil, and also prednisone. Initial presentation included features of polymyalgia rheumatica and nephrotic range proteinuria. Kidney biopsy showed membranous nephropathy. The patient was initially treated with methotrexate, while mycophenolate mofetil was discontinued. Clinical symptoms improved, but creatinine significantly increased, which led to discontinuation of methotrexate and mycophenolate mofetil was restarted. The kidney function improved, but the patient experienced a flare of rheumatoid arthritis. Costimulatory blocker, abatacept, was initiated and cyclosporine was gradually tapered off. Graft function remained stable for a follow-up period of 7 years. Joint pain, weakness, and stiffness resolved. Follow-up plain film radiographs at 5 years post initial presentation showed no new joint erosions in hands or feet. Costimulatory blockers may broaden the therapeutic choices of transplant recipients with de-novo autoimmune diseases.
