Infections, high temperature and many of the toxic substances can cause kidney damage. Acute kidney injury is a well known complication of some work-related diseases, e.g., lead intoxication. Chronic kidney disease can also be caused by some occupational factors. Three work-related nephropathies, in which causal connection with work has been proved, are discussed in this article. There are different risk factors of nephrolithiasis, lead nephropathy and silica nephropathy, but each of them can cause chronic kidney disease...

This is a case report of a 71-year-old male with known diabetes, hypertension and diabetic nephropaty who over the course of one year developed an unrecognized myopathy due to concomitant treatment with high-dose simvastatin and amlodipin. Due to rhabdomyolysis he was after seven days of treatment with roxithromycin admitted to hospital with loss of the ability to walk. We wish to raise awareness of the potentially severe side effects of simvastatin and to emphasize that these can be limited by increased attention to patients with risk factors and to interactions with other drugs...

CD11b and CD54 expression on neutrophils in patients with diabetic nephropathy (DN), arterial hypertension patients and healthy donors were examined. Development of DN associates with an increase of the number of CD11b and CD54 positive cells and violation of cellular co-operation. In the conditions of diabetic microenvironment expression of adhesion molecules rises substantially, what may characterized the mechanism of connection between hyperglycemia and vascular and tissues injury at DN. Authentication of morphological and biochemical markers of intercellular co-operation must in a prospect assist the deeper understanding of pathogenic mechanisms of DN...

Diabetic nephropathy (DN) is one of the most common causes of terminal stadium damage to the kidneys. The angiotensin-converting enzyme (ACE) represents a significant risk factor for the progression of DN. ACE inhibitors are medications of particular interest knowing the role of angiotensin II in the development of DN. This study aimed to examine the effects of ACE inhibitor treatment perindopril (PER), administered to rats with streptozotocin (STZ) induced DN, that developed albuminuria, renal hypertrophy and mild glomerulussclerosis...

UNLABELLED: Glomerular protein handling mechanisms have received much attention in studies of nephrotic syndrome. Histopathological findings in renal biopsies from severely proteinuric patients support the likelihood of protein endocytosis by podocytes. ClC-5 is involved in the endocytosis of albumin in the proximal tubule. AIM: To investigate whether ClC-5 is expressed in the glomerular compartment and whether it has a role in proteinuric nephropathies. ClC-5 expression was studied using Real-time PCR in manually- and laser-microdissected biopsies from patients with type 2 diabetes (n 37) and IgA nephropathy (n 10); in biopsies of membranous glomerulopathy (MG) (n 14) immunohistochemistry for ClC-5 (with morphometric analysis) and for WT1 was done...

For a long time, nephrotoxicity has been definitively defined as renal injury or dysfunction that arises as a direct or indirect result of exposure to drugs and industrial or environmental chemicals. There are a number of inherent difficulties in diagnostic procedures for toxic nephropathy, which include the absence of standard diagnostic criteria and the inability to relate exposure to a given agent and the observed effect. Critically ill newborns represent a high risk population for developing toxic nephropathy because of incomplete maturation of the kidney; furthermore, they are often treated with a combination of various therapeutic agents, each of them potentially inducing renal tissue injury...

Oxidative stress disturbs organism's homeostasis and leads to excessive reactive oxygen species (ROS) production. Researchers are still focused on antioxidants that help to reduce oxidative stress level and are helpful in treatment of diseases were ROS overproduction is observed. Among those antioxidants is lipoic acid (LA). When applied systemically LA accumulates in tissues and is converted to dihyrolipoic acid (DHLA) by lipoamide dehydrogenase. Both LA and DHLA are biologically active. LA scavenges hydroxyl radical, subchloric acid and singlet oxygen...

Immunoglobulin A nephropathy (N.IgA) is the world most common glomerular disease; 15-50% of patients develop loss of renal function in 10-20 years, and the rest remission or mild proteinuria/ hematuria. The optimal treatment is uncertain. Our aim was to develop evidence-based recommendations through research in Medline, Embasse, Lilacs and Cochrane Central Register of Controlled Trials. The study-quality was independently assessed by the reviewers following the Cochrane Renal Group checklist: randomization, blinding, intention-to-treat analysis and follow-up period...

ACE inhibitors and angiotensin receptor blockers confer renal protection in proteinuric nephropaties, but recently worsening of renal outcomes has been reported in non-proteinuric patients treated with a combination of ramipril and telmisartan, compared to ramipril only. In view of these apparently contradictory data, the review wants to shed light on treatment modalities of patients with hypertension and chronic kidney disease.

Iatrogenic kidney diseases may appeared as the consequence of medical mistakes or as the result of drug side effects. Present paper is dedicated mainly to this second group of disorders. Spectrum of different syndromes caused by the undesirable drug effects is very long and varied. There are among them water and electrolyte, disorders, tubulo-interstitial nephritis, glomerulopathies or acute renal failure. Also list of potentially nephrotoxic drugs is very long and including many different medicines. Additionally it is important to take into account existence of many risk factors enabling appearance of drug nephrotoxicity...

Pharmacological inhibition of the renin-angiotensin-aldosteron system (RAAS) constitutes a cornerstone strategy in the management of patients with chronic nephropaties and proteinuria. Angiotensin converting enzyme inhibitors (ACEI) as well as angiotensin II subtype 1 receptor antagonists (ARA) have been shown to decrease proteinuria, reduce the local renal inflammatory processes and slow the progression of renal insufficiency. Despite recent progress, there is still no optimal therapy which inhibits progression of renal disease...

UNLABELLED: HIV nephropathy (HIVAN) is the most frequent cause of chronic renal failure in HIV-infected black patients. However, the prevalence of other glomerulopathies mediated by immunocomplexes has increased in the last years. We report on the glomerular diseases observed in HIV patients in our Hospital. METHODS: A retrospective study of all patients with HIV infection and glomerular diseases diagnosed by renal biopsy. RESULTS: We found 27 patients with the following glomerular diseases: membranoproliferative glomerulonephritis (MPGN) in 8 patients, non-collapsing focal segmental glomerulosclerosis (FSGS) in 7, IgA nephropaty (IgA N) in 6, collapsing glomerulosclerosis in 4 (HIVAN, and membranous nephropaty (MN) in 2...

Prostaglandin E(2) (PGE(2)) belongs to a family of biologically active lipids derived from the 20-carbon essential fatty acids. Renal PGE(2) is involved in the development of the kidney; it also contributes to regulate renal perfusion and glomerular filtration rate, and controls water and electrolyte balance. Furthermore, this mediator protects the kidney against excessive functional changes during the transition from fetal to extrauterine life, when it counteracts the vasoconstrictive effects of high levels of angiotensin II and other mediators...

INTRODUCTION: It has always been thought that a reduction of renal tissue in childhood sometimes causes some irreversible injury in the remnant kidney as the years go by. The aim of this paper is to look over the presence of these changes and identify the risk of nephropaty throughout several parameters. MATERIAL AND METHODS: We reviewed 38 children, 23 males and 15 females, aged between 1 and 15 years, who had lost unilateral renal mass because of congenital or adquired diseases...

Angiodysplasia is an important cause of gastrointestinal bleeding in patients with chronic renal failure. Octreotide, a long-acting synthetic somatostatin analogue that reduces splachnic blood flow have been used to treat esophageal varicose hemorrhage, but its efficacy for bleeding vascular ecstasies is awaiting support. We present three patients with chronic renal failure (two with diabetic nephropaty and the third with mesangiocapilar glomerulonephritis and hepatic cirrosis), seric creatinine 3-4,5 mg/dl, and recurrent gastrointestinal bleeding due to diffuse angiodysplasia and vascular ecstasies, diagnosed by oral endoscopy, colonoscopy and video capsule...

UNLABELLED: Vascular diseases are the first cause of mortality within the occidental world. In Spain, they represent 35.5% within the total of deceases. Vascular diseases, jointly with Diabetic Nephropaty, are the first cause of inclusion of patients in dialysis. In precocious stages of renal disease, and as a consequence of the inflammatory condition generated already exists vascular damage. But its prevention is difficult, because habitually GFR is evaluated by means of plasmatic creatinin rate impeding the suitable detection of renal disease prevailing...

Increased interest in aneurysms involving the renal artery and its branches has occurred during the past 3 decades. The prevalence of renal artery aneurysms is approximately 0.01%-1% in the general population as well as 2.5% in hypertensive patients undergoing angiography. Intraparenchymal renal artery aneurysms (IPRAAs) are rare since being detected in less than 10% of patients with renal artery aneurysms. The Authors report an unusual case of multiple small intrarenal artery aneurysms associated with a large IPRAA located in the mid portion of the right kidney...
