Hyperuricemia is present in approximately 5% of the population, the vast majority of whom are asymptomatic and at no clinical risk. Complications, including renal calculi, uric acid nephropathy and gout, occur in a small proportion of patients. Allopurinol, an analog of hypoxanthine, has been widely used in clinical practice for over 30 years for the treatment of hyperuricemia and gout. Two percent of patients taking this medication develop a mild exanthema. A syndrome characterized by exfoliative dermatitis, hepatitis, interstitial nephritis and eosinophilia has been described previously. Termed allopurinol hypersensitivity syndrome, its etiology is related to the accumulation of one of the allopurinol metabolites, oxypurinol; clearance of oxypurinol is decreased in the setting of renal insufficiency and the use of thiazide diuretics. The term DRESS syndrome (Drug Rash with Eosinophilia and Systemic Symptoms) was recently introduced to describe a disorder associated with various drugs or viral infections and characterized by similar features. The pathophysiology of allopurinol-induced hypersensitivity, clinical presentation and treatment are reviewed.

We present a case of chronic hepatitis B with membranous nephropathy, that was improved by lamivudine treatment. A 37-year-old man was admitted to our hospital for the evaluation of proteinuria. He was diagnosed as having chronic glomerulonephritis associated with chronic hepatitis B. Histopathological findings of the renal biopsy specimen indicated membranous nephropathy. He suffered from nephrotic syndrome associated with leg edema, which was parallel to the exacerbation of hepatitis. Lamivudine was started for the treatment of hepatitis, which caused the disappearance of serum hepatitis B virus DNA and the normalization of ALT level in 4 weeks. Additionally, proteinuria disappeared 120 weeks after the treatment was started. Lamivudine treatment may remit HBV-associated nephropathy.

As survival continues to improve in the era of highly active antiretroviral therapy, kidney, liver, and cardiac disease have become increasingly important sources of mortality and morbidity in patients with HIV. The incidence of end-stage renal disease in patients with HIV is projected to increase, and the incidence of earlier chronic kidney disease, acute renal failure, and electrolyte abnormalities is likely to be much higher than appreciated. Both acute and chronic kidney disease are more common in the setting of advanced HIV, hepatitis coinfection or liver disease, and medication toxicity. Close collaboration between nephrologists and infectious disease specialists is important to facilitate the identification, diagnosis, and management of acute and chronic kidney disease in patients with HIV. Recently published guidelines highlight the increased awareness of kidney disease in the infectious disease community and provide guidelines for the detection and management of chronic kidney disease in patients with HIV.

Systemic lupus erythematosus (SLE) is a potentially fatal autoimmune multi-systemic rheumatologic disorder. An unusual case is reported of an 11.9-year-old Nigerian girl who was diagnosed after 2.8 years of non-specific symptoms and six episodes of recurrent haemolysis and pancytopaenia warranting blood transfusions. At diagnosis, she had hepatitis, polyarthritis, nephropathy, and cardiopulmonary and bone-marrow dysfunctions. Lymphopaenia, thrombocytopaenia, and direct antiglobulin-test positive haemolytic anaemia were present. Rapid resolution of disease activity followed exchange blood transfusion after an initial poor response to corticosteroid and cyclophosphamide therapy. Any child with recurrent haemolysis and pancytopaenia of unknown aetiology should be investigated for SLE.

The 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors or statins are the most successful cardiovascular drugs of all time. By interrupting cholesterol synthesis in the liver, they activate hepatocyte low-density lipoprotein (LDL) receptors and produce consistent and predictable reductions in circulating LDL cholesterol with resulting reproducible improvements in cardiovascular risk by retarding or even regressing the march of atherosclerosis in all major arterial trees (coronary, cerebral and peripheral). Clinical trials have demonstrated their capacity not only to extend life, but also to improve its quality by retarding the progression of diabetes mellitus and chronic renal disease and by enhancing central and peripheral blood flow. They are amongst the most extensively investigated pharmaceutical agents in current clinical use. In cardiovascular end-point trials they have proven ability to help prevent that first and all important myocardial infarction and to reduce the likelihood of a recurrence in those who do succumb. They are equally effective in men and women of all ages and at all levels of cardiovascular risk, whether caused by hypercholesterolaemia, hypertension, cigarette smoking, diabetes mellitus or the metabolic syndrome. In addition, they improve the outlook of patients with familial hypercholesterolaemia whose LDL receptor function is deficient or defective; and all of this comes at minimal risk to the recipient. Their most important potential side effect is myopathy, which on very rare occasions may lead to rhabdomyolysis. Clinical experience shows that myopathic symptoms with creatine kinase levels raised to more than 10 times the upper limit of normal is seen in <0.01% of recipients and progression to fatal rhabdomyolysis because of renal failure has been recorded in only 0.15 cases per million prescriptions. Liver function abnormalities are also, rarely, seen. Again, the frequency of raised aspartate or alanine aminotransferase to more than three times the normal limit is encountered in no more than 1-2% of all treated patients and is completely reversible upon withdrawal of treatment. Progression to hepatitis or liver failure does not occur. This constellation of benefits with little side effect penalty has resulted in the comparison of statins with antibiotics in the global battle against cardiovascular disease.

In 1997, a new DNA virus, designated TTV "Transfusion Transmitted Virus", was isolated and seemed to be associated with non A-G post-transfusion hepatitis. The virus infects mainly patients at risk for parenteral exposure and hence, prone to develop chronic liver disease, as well as healthy populations worldwide. Few reports, however, have been published on the epidemiology and potential significance of TTV infection in patients with renal disease. This paper reviews, characterization of the virus, the history of its discovery, taxonomy and identification. Current status of TTV infection in patients with renal diseases are also summarised.

Insulin resistance (IR) in childhood has importance to the understanding and prevention of the growing epidemic of insulin resistance syndrome (IRS) in adults with attendant obesity, type 2 diabetes (T2DM), atherosclerotic diseases, hypertension, gout, non-alcoholic, steato-hepatitis (NASH), gall bladder disease, nephropathy, polycystic ovarian disease (PCOS), infertility and premature senility. The severity of IR and its' complications in children unfortunately and usually progresses in their pubertal transition to adulthood; affected young children are more likely than adults to have underlying causal monogenic disorders; the sequence of natural history and events give insights into disease pathogeneses, and optimal life style choices that last are best made during the early formative years. Some features of IR in children discussed herein are: a strong tendency to low birth weight for gestational age, adverse effects of adrenarche and therapeutic steroid therapy, predisposition to premature pubarche, acanthosis nigricans, tall stature despite pituitary GH suppression, allergic diathesis, hyperandrogenism and PCOS, dyslipidemia and fatty liver disease, and diagnosis by clinical and biochemical markers of IR including insulin regulated hepatic hormonal binding proteins such as IGFBP-1. The national preoccupation with the "metabolic syndrome" T2DM and obesity, should be appropriately directed to an improved understanding of IR in children and their management, if the looming health crisis in affected adults is to be seriously addressed. The nation is facing its' first generation of children who will be less healthy and die younger than the previous generation (Marks (2005) Presentation to the American Association of Diabetes Educators 32nd Annual Meeting and Exhibition, August 10-13, Washington, DC).

Diffuse hepatic calcification is a rare condition. Previous reports have described patients with end-stage renal disease who developed diffuse hepatic calcification after ischemic hepatitis caused by shock. We herein present a similar case. A 41-year-old man on chronic hemodialysis developed ischemic hepatitis due to shock induced by ventricular tachycardia, followed by progressive hepatic failure. Necropsy of the liver revealed diffuse hepatocellular calcification. Given the similarity by which our case and previously reported cases developed this rare condition, we postulate that chronic renal failure is involved in the pathogenesis of diffuse hepatic calcification.

Renal diseases associated with hepatitis C virus (HCV) infection are a significant problem for clinicians and diagnostic pathologists. A wide variety of disorders, including a spectrum of immune-complex glomerulonephritides, has been reported in association with hepatitis and cirrhosis caused by HCV. For some of these diseases, including membranoproliferative glomerulonephritis type I and cryoglobulinemic glomerulonephritis, plausible links between HCV and the glomerular pathology have been proposed. In other cases, the role of the virus in the pathogenesis of the renal disease is less certain. This communication catalogues the renal manifestations of HCV infection, providing clinical and pathological descriptions of the most prevalent disorders. Where available, evidence implicating HCV in the causation of the disorders is also discussed.

Bentazone is a herbicide widely used in the agrochemical field and acts by interference in photosynthesis in plants. Case reports of bentazone poisoning in humans are rare, but hepatorenal damage and death have been described, though the mechanism of toxicity remains speculative. We describe 2 cases of acute bentazone poisoning and compare these with other literature reports. The clinical picture included nausea, vomiting, diarrhea, abdominal pain with gastrointestinal corrosive injury, dyspnea and acute hepatorenal dysfunction. Respiratory failure, acute hepatitis, acute renal failure requiring hemodialysis, and death occurred following a large ingested dose of 1,764 mg/kg. Bentazone may have direct organ toxicity, especially in liver and kidney, in subjects with renal hypoperfusion, rhabdomyolysis, preexisting renal disease or concomitant nephrotoxic drug consumption. Aggressive supportive therapy, hydration and measures to prevent renal hypoperfusion are essential to reverse acute renal failure.
