An 8 year old, intact female, Old English Sheepdog was presented with lethargy and chronic weight loss of one year duration. The dog suffered from recurrent fever and a mild peripheral lymphadenopathy. Mild thrombocytopenia, monoclonal hyperglobulinemia and positive Ehrlichia canis antibody titer were indicative of Ehrlichiosis. The patient developed proteinuria and renal failure, which suggested the presence of glomerulopathy. Immunohistochemical staining of renal biopsy specimen demonstrated AA amyloidosis. Chronic ehrlichiosis was suspected to be the cause of the dog's renal amyloidosis.

A case is reported of a 21 year old man who suffered from Castleman's disease and systemic secondary amyloidosis. He was otherwise healthy until development of a history of edema and nocturia over 3 weeks. Physical examination was normal apart from ankle swelling. Renal biopsy showed amyloid deposits in the glomerulus with gentian violet and congo red. Positive staining by antibody against serum amyloid A protein was demonstrated. Nine months later because of persistent nephrotic syndrome, an abdominal tomography was performed and a mesenteric mass was detected. The patient underwent abdominal surgery. The histopathological examination showed plasma cell variant of Castleman disease and AA amyloidosis in the mass. After the removal of mesenteric mass, the proteinuria gradually decreased and disappeared, and no systemic findings were present.

Secondary amyloidosis is caused by the extracellular store of the fragment AA of the circulatory protein in serum amyloid-A. It can complicate diseases such as family mediterranean fever, rheumatoid arthritis or Crohn's disease. Renal amyloidosis is a rare but serious complication of Crohn's disease. We report two cases of Crohn's disease associated with a nephrotic syndrome due to renal amyloidosis. It is important to recognize this complication, especially since Colchicine has been proposed as a possible treatment. So, the search for proteinuria seems to be important for an early diagnosis of renal amyloidosis in Crohn's disease.

Secondary amyloidosis is usually a complication of chronic inflammation. Amyloidosis cases during the course of non-Hodgkin's lymphoma (NHL) are usually of AL-type, only one NHL patient with secondary amyloidosis has been reported. Our 79-year-old male patient visited us with multiple lymphadenopathies, and he was diagnosed with nodal marginal zone B-cell lymphoma. After four cycles of combined chemotherapy; his urea, creatinine levels started to increase and he developed nephrotic-range proteinuria. His rectal biopsy demonstrated amyloid deposition in submucosal vessel walls. The patient has been under hemodialysis for 10 months and his lymphoma is still in partial remission. We presented this case because it is the second NHL patient who developed secondary amyloidosis during his disease course.

We describe a patient with a long history of familial Mediterranean fever who developed proteinuria as a result of secondary AA amyloidosis. In this patient, the inflammatory process, including recurrent attacks of arthritis, abdominal pain, nephrotic syndrome secondary to amyloidosis, and high sedimentation rate, was rapidly suppressed by treatment with infliximab and there was remarkable improvement of the proteinuria.Because TNF-alpha is a proinflammatory cytokine that plays a major role in FMF and secondary amyloid, it is an appropriate target for therapy. Our case is the first case of reactive systemic amyloidosis secondary to familial Mediterranean fever, which responded favorably to infliximab.

A 41 year-old male was admitted because of nephrotic syndrome associated with renal impairment and arterial hypertension. Renal biopsy showed a complete subverting of renal architecture with eosinophilic, amorphous deposits which stained positive for Congo red and were positive for antibodies against AA-amyloid. Abdominal fat pad aspirate confirmed the diagnosis of AA amyloidosis. Despite high values of serum amyloid A (SAA), surprisingly medical history, physical examination and all tests failed to identify any underlying inflammatory disease, even asymptomatic, at presentation and during the whole follow-up period. The patient carried a mutation (Glu148Gln) in the MEFV gene, and a mutation (Arg92Gln) in the TNFRSF1A gene, both in heterozygosity. The patient has never complained of the typical features of the Familial Mediterranean fever or of the TNF receptor-associated periodic syndrome. The patient's father carried the same mutations. His father's medical history was unremarkable; renal tests, acute-phase reactants and SAA were normal. During a trial with colchicine (while the patient was also taking atorvastatin) SAA decreased, renal function continued to deteriorate and proteinuria remained high; no cardiac involvement was detected. Six months later our patient developed rhabdomyolysis, thus accelerating the decline of renal function and requiring the start of dialysis.

Amyloidosis is an uncommon cause of renal disease in HIV-positive patients. Diagnosis is challenging, treatment options are limited, and prognosis remains poor. We discuss an HIV-positive patient with acute renal failure and nephrotic range proteinuria. The differential diagnosis included nephropathy due to trimethoprim/sulfamethoxazole, tenofovir, HIV, hepatitis C, heroin, or multifactorial causes. Serum and urine study findings were inconclusive. Rapid clinical deterioration ensued and a renal biopsy was performed. Pathologic examination revealed eosinophilic, amorphous material in the glomerular tufts that stained red-orange with Congo red stain. Immunohistochemical analysis confirmed amyloid A (AA) amyloidosis. AA amyloidosis occurs as a complication of chronic infection or chronic inflammatory disease. It has been reported in intravenous or subcutaneous drug abusers, some of whom were HIV-positive. This case underscores the importance of tissue diagnosis to determine the cause of renal disease in HIV-positive patients. Clinical diagnosis, based on CD4 count, viral load, and degree of proteinuria, may not predict the pathological diagnosis in HIV-positive patients.

Autosomal-dominant polycystic kidney disease is an inherited disorder characterized by the development and growth of cysts in the kidneys. Urinary protein excretion is generally less than 1 g/day, and the association of the nephrotic syndrome with this condition is considered rare. A 39-year-old man with autosomal-dominant polycystic kidney disease and nephrotic-range proteiuria is described. During admission, he had general edema and a diagnosis of pulmonary tuberculosis. The patient had hyperlipidemia, hypoalbuminemia, and 11.8 g/day proteinuria. The gingiva and rectum biopsies were performed in order to evaluate the etiology of nephrotic syndrome, and revealed AA amyloidosis thought to be secondary to pulmonary tuberculosis. We maintained the antituberculous treatment and began colchicine at a dose of 2 g/day and candesartan 8 mg/day. To our knowledge, this is the first autosomal-dominant polycystic kidney disease case with nephrotic syndrome due to amyloidosis secondary to pulmonary tuberculosis.

Secondary (AA) amyloidosis is one of the most significant complications of ankylosing spondylitis (AS) that frequently leads to proteinuria and renal dysfunction. Anti-tumor necrosis factor alpha (anti-TNF) agents are promising in inducing clinical remission by suppressing systemic inflammation in AA amyloidosis. We report three cases with AS-related AA amyloidosis that responded well to etanercept therapy. Despite treatment with disease modifying anti-rheumatic drugs, all three patients had active AS, marked proteinuria, impaired renal function, and low serum albumin level. During 1-year treatment with etanercept, all patients experienced gradual improvement in all of these parameters.

Secondary amyloidosis (AA amyloidosis) has rarely been described in patients with systemic lupus erythematosus (SLE). We, herein, present a 56-year-old female patient, who developed AA amyloidosis following a 22-year history of SLE. She developed severe mitral regurgitation complicated with chordae tendinea rupture that led to acute congestive heart failure and went on a mitral valve replacement, where no flare symptoms of SLE were present. Three months after the operation, she presented with a nephrotic-range proteinuria, acute renal failure, and severe sepsis. She was found to have new vegetations on replaced valve and multi-organ failure caused her death. Re-evaluation of the excised mitral valve revealed AA amyloid deposition. Post-mortem biopsies from the kidney and bone marrow also revealed secondary amyloidosis.
