A single case of gastric plasmacytoma showing unusual clinical and pathological features is described. The patient had gluten sensitive enteropathy, and showed increased circulating IgA levels prior to gastrectomy. Progression of the disease was associated with both K and L light chain proteinuria, hypoalbuminaemia, and vasopressin resistant polyuria. Pathological investigation revealed the coexistence of IgA secreting soft tissue plasmacytoma, with IgG secreting myeloma. The significance of these findings is discussed.

Acute renal failure was diagnosed by clinical, necropsy and histological criteria in 39 flocks (20 low ground, 13 hill and six marginal upland) in areas served by six veterinary investigation centres. Forty-eight lambs of 12 different breeds or crosses were investigated. The mean age of affected lambs was 38 days (range seven to 84 days); 21 lambs (44 per cent) were aged seven to 28 days, while only eight (17 per cent) were older than two months. Mortality in clinically affected lambs was almost 100 per cent, with no response to various treatments. Histological examination showed that 40 lambs (83 per cent) had nephrosis, while the rest had toxic tubular necrosis, interstitial nephritis or tubular damage associated with oxalate crystal deposits. Only about half of the lambs had any evidence of enteric infections or enteropathy. Acutely ill lambs had azotaemia, haemoconcentration and proteinuria; some lambs had glycosuria or haematuria. Samples of plasma from 22 lambs with nephrosis were compared with similar samples from 82 incontact but asymptomatic lambs. The clinically affected group had significantly elevated plasma urea, creatinine, total protein, globulin, phosphorus and chloride concentrations and significantly reduced plasma calcium concentrations compared with healthy lambs. Affected lambs had a significant reduction also in the calcium:phosphorus ratio. No significant differences between groups was found in plasma concentrations of albumin, glucose, lactate, glycerol, creatine kinase, alkaline phosphatase, sodium, potassium or magnesium.

A 57-year-old man with long-term untreated Crohn's disease presented with exacerbation of his bowel disease, volume depletion, nephrotic syndrome and rapid decline in renal function. Renal biopsy revealed amyloidosis and extensive interstitial infiltration. Initiation of steroid therapy was associated with improvement in renal function and postponement of dialysis, suggesting that control of interstitial inflammation might have a therapeutic role in renal amyloidosis. We hypothesize that volume depletion could magnify toxicity of proteinuria, thus augmenting interstitial inflammation and accelerating the deterioration in renal function.

Several reports have documented various forms of glomerular diseases in adults with myelodysplastic syndromes (MDS), but similar reports in children are lacking. We describe two children with MDS-associated steroid-responsive nephrotic syndrome (NS). Patient 1, who had MDS with myelofibrosis, presented with hepatosplenomegaly, pancytopenia, chronic hepatitis, moderate proteinuria, hypocomplementemia and elevated ANA titer. During initial prednisone treatment proteinuria markedly diminished and partial but transient hematological improvement occurred. Relapse subsequently occurred that manifested by overt NS and pancytopenia. High doses of prednisolone led to remission of the renal disease, but hematological remission did not occur. Persisting pancytopenia and repeated infections terminated in sepsis, 2 years after the onset of the MDS. Patient 2, who had refractory anemia with clonal monosomy 19, presented with bowel disease, hepatosplenomegaly, anemia and non-organ-specific autoantibodies. Prednisone led to both clinical and hematological remission. The hematologic disease relapsed 12 months later, when nephrotic-range proteinuria, hematuria and mild azotemia were also found. Corticosteroid treatment led to long-lasting renal and hematologic remission, maintained by a small dosage of prednisone. In both patients, renal biopsy findings were consistent with those seen in idiopathic NS. A Medline search disclosed 16 cases of glomerulopathy in the course of MDS in adult patients. Clinical features included NS, usually accompanied by renal insufficiency with acute, chronic, or rapidly progressive glomerulonephritis. On biopsy, membranous nephropathy, crescentic or mesangial proliferative glomerulonephritis, and AL amyloidosis were found. We conclude: (1) that glomerular disease may be present and should be searched for in patients with MDS and (2) that MDS can be added to the list of rare conditions associated with corticosteroid-responsive NS in children.

Amyloidosis is a disease resulting from extracellular deposition of fibrillar protein in various organs. AA amyloidosis may complicate chronic inflammatory diseases, chronic infections and another chronic diseases. We review 31 patients (13 males and 18 females) with biopsy proven renal or rectal AA amyloidosis, referred to out hospital between january 1999 and november 2002. Renal failure was defined as serum creatinine > or = 1.5 mg/dl. Mean age was 58.4 +/- 15.7 years. The causes of AA amyloidosis were an underlying chronic rheumatologic disease (51.6%), chronic infection (41.9%) and a chronic inflammatory intestinal disorder (6.5%). Renal failure (RF) was detected in 20 patients (61.2%) and proteinuria and hematuria were found in 90.3% and 45.5 respectively. Proteinuria at diagnosis was 5.2 +/- 3.9 g/24 h and mean serum creatinine 3.5 +/- 3.7 mg/dl. Survival of patients without dialysis was 66.8 (51.1% RF, 90.9% non-RF) and 53.4% (38.2 RF, 77.9% non-RF) at 12 and 24 months respectively (p = 0.017). End-stage renal disease developed in 13 patients (41.9%). Ten patients were maintained on hemodialysis and 3 on CAD. Survival in dialysis at 6 and 12 months was 68.3% and 42.7% respectively. Fifteen patients died and the main causes of death were: infections (46.6) haemorrhagic complications (33.3%), cardiovascular events (13.3%) and cachexia (6.6%).

Protein losing enteropathy (PLE) is a gastrointestinal disorder that is associated with excessive loss of plasma protein into the gut resulting from abnormal mucosal permeability. The disease is usually caused by inflammation. The loss of protein in PLE is a nonselective process affecting albumin, globulin and transferrin. Abdominal scintigraphy with human serum albumin marked by Tc99m seems to be an easy and sensitive method for diagnosing PLE. An 4-year-old girl was presented to an outside Pediatric Department due to hypoproteinemia and recurrent pneumonia which had caused several prior hospitalizations. The laboratory tests revealed hypoproteinemia, hypoalbuminemia, low level of IgG, sideropenia, and a decreased level of T lymphocytes. The loss of protein into the gut was confirmed by fecal clearance of alfa-1 antitrypsin. Only nonspecific inflammation was detected by biopsy of the small intestine. These clinical and laboratory findings, quickly decreasing IgG and albumin levels in spite of i.v. supplementation and the lack of proteinuria permitted PLE diagnosis. The abdominal scintigraphy was planned to assess and localise protein losing through GIT and for strategy of possible surgical treatment. Abdominal dynamic scintigraphy was performed immediately after the injection of 300 MBq Tc99m human albumin. 90 images were taken within 180 minutes. Delayed abdominal images were obtained 6 and 24 hours after the tracer injection. Anterior abdominal scintigraphy showed pathological activity of Tc99m-albumin in small bowel in the upper left segment of the abdomen in the 40th minute after injection. Extensive accumulation of albumin was seen in the 160th minute. Delayed images, after 3 and 6 hours, revealed translocation of the tracer into the lower right abdominal segment. The further passage and tracer concentration was detected in ascendant and transverse colon. Based on the laboratory tests and scintigraphic images the girl was suspected to have segmental lymphangiectasia of small intestine and was qualified for laparatomy and, possibly, for surgical resection of the pathologically changed bowel. However, diffuse pathological changes revealed in the guts during the operation, rendered the operation impossible. Tc99m-labelled human serum albumin scintigraphy may be considered the method-of-choice in the diagnosis of protein-losing enteropathy. However, in this test the assessment of the enteropathy dimension is difficult and surgical treatment should be planned with caution.

We present a patient with Fabry disease with remarkable diagnostic findings and gluten-sensitive enteropathy. An 11-year-old girl was admitted to hospital with weight loss, anorexia, nausea, vomiting, flank pain, acroparesthesia, and painful extremities. Her mother had end-stage renal failure secondary to Fabry disease. On physical examination, she had growth retardation. Ophthalmological examination showed characteristic whorl-like corneal opacities and Fabry disease was confirmed with low alpha-galactosidase A (alpha-gal A) activity. Her painful attacks were treated with carbamazepine, but vomiting and nausea continued. Laboratory studies revealed positive serum anti-endomysium and anti-gliadin antibodies. Small intestinal biopsy showed subtotal villous atrophy compatible with gluten-sensitive enteropathy. Following treatment with a gluten-free diet, her gastrointestinal symptoms completely disappeared within a few weeks and then she had catch-up growth. In her long-term follow-up, proteinuria appeared and renal involvement was confirmed by characteristic renal biopsy findings. Following these clinicopathological findings, enzyme replacement therapy was started. In conclusion, although heterozygous females can be asymptomatic or are expected to have a mild course of the disease, a severe clinical course in our patient in the 2nd decade is of particular interest. In addition, Fabry disease occurring with gluten-sensitive enteropathy, a very rare co-existence, is emphasized.

Ulcerative colitis is rarely associated with immunoglobulin A nephropathy (IgAN). The development of IgA nephropathy complicates further the clinical course of patients with ulcerative colitis. A 72-year old man with a 30-year history of ulcerative colitis requiring colectomy and modest renal insufficiency secondary to complications of nephrolithiasis and renal artery stenosis developed glomerular hematuria, proteinuria and progressive renal failure. Percutaneous kidney biopsy revealed IgAN with extensive glomerular and interstitial sclerotic changes. After resection of a chronically infected ileo-rectal pouch, renal function improved, while hematuria and proteinuria gradually disappeared without specific treatment of the IgAN. The manifestations of IgAN complicating ulcerative colitis can be improved with effective treatment of the bowel disease even when there are extensive sclerotic changes in the kidneys.

We report on a 6-month-old child presenting with chronic diarrhea, failure to thrive, eczema, autoimmune hemolytic anemia (AIHA), insulin-dependent diabetes mellitus (IDDM), hypoalbuminemia, and proteinuria. Renal biopsy showed membranous glomerulonephritis. A diagnosis of Immunodysregulation, polyendocrinopathy, enteropathy, x-linked (IPEX) syndrome was subsequently confirmed by DNA analysis, which demonstrated the presence of a mutation in exon 2 of the FOXP3 gene (303-304 del TT). Proteinuria secondary to membranous glomerulonephritis is a novel feature of IPEX syndrome. Membranous glomerulonephritis went into remission after the patient had received hematopoietic stem cell transplantation (HSCT).
