Serum mannose concentration increases in diabetic patients and correlates closely with blood glucose. In patients with glomerulonephritis, serum mannose and mannose/glucose ratio positively correlate with dyslipidemia and the extent of urinary protein excretion. We investigated whether changes in serum mannose mark subjects with features of metabolic syndrome, including obesity, hypertension, glucose intolerance, and dyslipidemia. The study comprised 20 patients with mean age of 68 (SD 11) years, body mass index 27.2 (SD 5.1) kg/m2, blood glucose 6.2 (SD 1.6) mmol/L, serum total cholesterol 6.3 (SD 1.2) mmol/L, triglyceride 2.0 (SD 0.08) mmol/L, uric acid 320 (SD 109) micromol/L, mannose 60.0 (SD 17) micromol/L, and mannose/glucose ratio 9.7 (SD 1.8) micromol/mmol. Serum mannose correlated with blood glucose (r=0.758, p=0.012), triglyceride (r=0.478, p=0.023), and HDL-cholesterol (r = approximately 0.427, p=0.022). Mannose/glucose ratio correlated with BMI (r=0.581, p=0.033), mannose (r=0.491, p=0.035), and uric acid (r=0.608, p=0.027). The rate of VLDL lipoprotein turnover may be instrumental in the regulation of serum mannose concentration. We conclude that an altered mannose metabolism is a novel consideration among the metabolic abnormalities in the metabolic syndrome.

A 45-year-old nondiabetic man presented with features resembling diabetic triopathy. He worked in a rayon manufacturing plant and was exposed to toxic levels of carbon disulfide (CS(2)). Clinical abnormalities included peripheral and central nervous system abnormalities as well as retinopathy, dyslipidemia, cardiovascular disease, and nephrotic syndrome. He later developed focal sclerosing glomerulonephritis. The latter has not previously been described in cases of CS(2) exposure. Terminally, he developed end-stage renal disease and progressive dementia, both of which were thought to be consequences of CS(2) exposure earlier in life.

Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease marked by immune-complex mediated lesions in small blood vessels of various organs, especially the kidneys, although other factors may also be implicated in the pathogenesis of the disease. This article focuses on the role of lipids in the progression of glomerular, vascular and tubulo-interstitial lesions in two patients with lupus nephritis associated with pronounced hyper- and dyslipidemia. The pathogenesis of progressive glomerulosclerosis in both patients appears to be multifactorial. In addition to immune complex mediated lupus glomerulonephritis, progressively active in the first patient, severe nephrotic-range persistent proteinuria, arterial hypertension associated with hyperfiltration and hyperperfusion injuries and, to a minor extent, hyper- and dyslipidemia were observed. Immunological and non-immunological factors were shown to contribute to the development of tubulo-interstitial lesions. In both patients, in addition to local immune deposits, prominent tubulo-interstitial lipid deposits were probably causally related to both hyperlipidemia and the increased permeability of the glomerular filtration barrier. Tubular lesions were highlighted by intracytoplasmic lipid droplets as well as small cleft-like spaces found to be impacted in the tubular lumina. They were seen to penetrate tubular epithelial cells and eventually lodge in the interstitium, surrounded by mononuclear cell infiltrates and foam cells. In both patients, hypertensive angiopathy and extraglomerular vascular immune deposits were demonstrated. In addition, in the second patient, arteriolar and small arterial hyaline was found at the age of 28 years to be full of lipids and calcium precipitates, suggesting a peripheral atherosclerosis-like process which never occurs as a natural age-related condition. In conclusion, all parts of the nephron may be involved in the pathogenetic process causally related or influenced by hyper- or dyslipidemia. Associated either with endothelial cell injury and consequent insudation of lipids in the vascular walls, glomerular filtration barrier injury with hyperfiltration, or tubulo-interstitial lipid deposition, the mechanism of tissue damage by lipids in all parts of the nephron shares similarities with the pathogenesis of systemic atherosclerosis.

Vascular calcification is a common feature in chronic dialysis patients, but their clinical significance is debated and the role of kidney transplantation (TP) in the natural history of their development has received scanty attention. We will describe a case of dramatic worsening of vascular calcifications during TP in a young patient in spite of early and successful parathyroidectomy (PTX), and will discuss other causes which might be putatively linked to vascular damage during the time of TP. A 37-year-old man on regular dialytic treatment (RDT) for 11 years, received his first cadaveric transplantation in January 1993. He underwent PTX 6 months after TP because of the lack of decreasing in parathyroid hormone values despite normal graft function. Although PTX was effective, a dramatic worsening was evident in large as well as in medium and small-sized arteries during the following three years of TP. In February 1997, few months after starting dialysis again because of the recurrence of his primary membranoproliferative glomerulonephritis (MPGN), the patient experienced myocardial infarction followed by aorto-coronary bypass (right coronary artery and anterior descending coronary artery) and leg "claudicatio". Though a role for parathyroid hormone in vascular disease has been commonly accepted, the case here reported clearly shows that blunting parathyroid gland activity may be unable to avoid the worsening of a process of vascular disease during the time of TP. Many other factors--linked to the time of TP--may be involved in vascular diseases, such as nephrotic syndrome, dyslipidemia, hypertension and drugs. In the case of our patient, a clear cut risk factor for his progressive atherosclerosis can be designated hyperlipidema and other disturbancies secondary to a nephrotic syndrome due to relapse of MPGN, together with persistent hypertension. This is the first case report in the English literature which clearly demonstrates that TP may add fuel to the fire of vascular disease also in young people and even in the absence of parathyroid hyperactivity, perhaps on the basis of a favorable genetic background. Furthermore, the history of our patient demonstrates that vascular calcifcation heralds major cardiovascular diseases.

Psoriasis is an immune-mediated chronic inflammatory disorder of the skin. Association with kidney disease has been debated for a long time. Secondary renal amyloidosis in psoriatic arthropathy and drug-induced renal lesions secondary to methotrexate or cyclosporine are accepted accompaniments of psoriasis. IgA nephropathy is also known to occur in psoriatics. We report three interesting cases of renal involvement in long-standing established psoriasis on topical therapy alone. The patients presented with hypertension, significant proteinuria, hypoalbuminemia, and dyslipidemia. Kidney biopsies revealed "mesangioproliferative glomerulonephritis with IgA nephropathy," "focal proliferative glomerulonephritis," and "membranous glomerulonephropathy." The former two had marked active urinary sediment. Patients improved on prednisolone and angiotensin-converting enzyme inhibitors. Contrary to the belief that renal involvement in psoriasis is coincidental, we propose that kidney disease may be a common accompaniment of psoriasis, which may be labeled as "psoriatic nephropathy" or "psoriatic kidney disease." The exact mechanism of this entity is yet to be elucidated.

Hyperlipidemia has been well recognized as a striking feature of nephrotic syndrome and other renal diseases. However, the underlying pathophysiological mechanisms still have not yet been elucidated. In this study, we evaluated acylation-stimulating protein (ASP) and complement component 3 (C3) in children (n=48) with various forms of proteinuric renal disease [nephrotic syndrome, acute poststreptococcal infection glomerulonephritis (APSGN), and lupus nephritis (LN)] in comparison with age- and gender-matched controls (n=279). In children with proteinuric renal disease, various aberrations in plasma lipids were noted, including increased triglyceride, cholesterol, and low-density lipoprotein cholesterol (LDL-C) (all p<0.0001). Whereas C3 was not altered in children with nephrotic syndrome (1.05+/-0.05 g/L vs. 1.29+/-0.04 controls), the decrease was pronounced in children with LN and APSGN (0.42+/-0.11, p<0.05 and 0.30+/-0.06, p<0.001, respectively). Plasma C3 correlated positively with lipid parameters [triglyceride, cholesterol, LDL-C, apolipoprotein B (apoB), high-density lipoprotein cholesterol (HDL-C) and apoA1] and inversely with total protein, blood urea nitrogen, and creatinine. By contrast, plasma ASP was significantly elevated in all proteinuric renal diseases (101.4+/-7.1 nmol/L nephrotic syndrome, 90.9+/-14.1 LN, and 81.8+/-7.2 APSGN vs. 44.3+/-1.5 controls, p<0.05 to p<0.001), and this increase was correlated with changes in lipid parameters (triglycerides and apoA1). In summary, these results demonstrate alterations in C3 and ASP that may contribute to or compensate for dyslipidemia.

The number of renal transplant recipients is increasing steadily. Physicians from all specialties are ever more likely to encounter this vulnerable group of patients. They constitute a susceptible group because of increased mortality and morbidity. Half of the renal transplants are lost due to chronic transplant failure. The primary cause of chronic transplant failure is chronic allograft nephropathy. Other causes of transplant failure are calcineurin inhibitor toxicity, recurrence of the original renal disease such as glomerulonephritis and diabetes mellitus, stenosis of the renal artery in the transplant, and urological complications. The other half of the renal transplants are lost due to the death of the recipient. The primary cause of death is cardiovascular disease due to former chronic renal, hypertension and dyslipidemia following the use of immunosuppressants. In addition malignancies, infections and bone abnormalities do occur more frequently as compared to the normal populations. Alertness is warranted following kidney transplantation by both the patients themselves as well as all the treating specialists. Careful periodical monitoring for life is required because of the risk of the abovementioned complications.

A 86-year-old man had been treated for hypertension, diabetes mellitus (DM), and dyslipidemia in Nihonkoukan Hospital. His renal function was within the normal range in August 2007. He showed common cold-like symptoms, which were not improved by anti-inflammatory drugs in December 2007. He was admitted to our hospital because of renal failure, urine protein and urine occult blood. He was also positive for anti-myeloperoxidase antibody (MPO-ANCA; 129 IU/mL). A renal biopsy revealed idiopathic crescentic glomerulonephritis of the pauci immune type. Considering his advanced age and DM, he was treated with the low dose of 20 mg/day of prednisolone. Although his symptoms, such as low grade fever and general fatigue, were improved after steroid therapy, renal failure accelerated, necessitating hemodialysis (HD), and insulin administration was needed for his DM. Subsequently, an AV fistule operation for HD was performed. Prednisolone was tapered to 17.5 mg/day after 4 weeks, and his MPO-ANCA titer decreased to 87 IU/mL. After steroid treatment and HD, his condition gradually recovered and he was discharged on March 5, 2008. Following about 6 months of treatment with prednisolone (3.5 months after HD administration), his renal function gradually recovered, allowing the discontinuation of HD. High-dose steroid therapy is very effective for ANCA-related glomerulonephritis. However, there is a high risk of infection, especially in aged and DM patients. Low-dose steroid therapy (PSL 20 mg/day) is safe and effective in such high-risk patients and in some cases, they can be released from HD.

We describe the case of a 67 year-old female who presented weakness and fatigue. Laboratory data showed nephrotic level of proteinuria and dyslipidemia. A renal biopsy was performed, and studied by light microscopy, immuno-fluorescence and electron microscopy. Ultra-structural analysis revealed the existence of organized fibrillary deposits, straight and without ramifications, the thickness of which ranged from 15 to 20 nm. These fibres were identified, by light microscopy, as slightly nodular mesangial expansions PAS positive, Congo red negative and weakly positive for IgG. Given the above findings, the diagnosis was fibrillary glomerulonephritis. Glomerular lesions with organized deposits may exhibit syndromic and pathological overlap. For this reason it is important to initially discriminate between positive and negative Congo red deposits, using, in the latter case, transmission electron microscopy to distinguish between immuno-tactoid and fibrillary glomerulonephritis. This differentiation relies not only on ultrastructural features, but on different clinical characteristics. Unlike what happens with fibrillary glomerulonephritis, the immuno-tactoid shows a strong association with lymphoproliferative processes.

A patient with advanced gastrointestinal stromal tumor (GIST) receiving second-line treatment with sunitinib developed edema, increase of the serum creatinine, weight gain, nephrotic syndrome with proteinuria of 12 g/24 h, dyslipidemia, hypoalbuminemia and also presented with hypertension. A kidney biopsy showed an immunocomplex glomerulonephritis. Steroid treatment was started, but the clinical conditions and laboratory values did not improve. So in the hypothesis that the nephrotic syndrome was induced by sunitinib, sunitinib was temporarily discontinued with a subsequent reduction of proteinuria and improvement in blood pressure control. In the last years, the introduction of sunitinib has modified the natural history of advanced GIST. However, due to chronic and prolonged intake of this drug, there is increasingly frequent detection of late and unknown toxicities in clinical practice. In particular, the late renal toxicity from sunitinib may be the primary clinical problem with this drug in the case of prolonged treatment. Monitoring of kidney function and blood pressure should be performed for early detection of side effects such as hypertension and kidney dysfunction in advanced GIST patients receiving long-term treatment with sunitinib. A clinical collaboration between oncologists and nephrologists could be useful with the objective to optimize the management of sunitinib.
