    The sarcoidosis is a systemic granulomatosis affecting most frequently the lungs and the mediastinum. An acute renal failure reveals exceptionally this disease. It's a retrospective study implicating 12 cases of sarcoidosis complicated of acute renal failure. The aim of this study is to determine epidemiological, clinical, biological and histological profile in these cases and then to indicate the interest to consider the diagnosis of sarcoidosis in cases of unexplained renal failure. Extra-renal complications, therapeutic modalities and the outcome were determined in all patients. Our series involved 12 women with an average age of 40 years. Biological investigations showed an abnormal normocalcemia in 7 cases, a hypercalcemia in 5 cases, a hypercalciuria in 10 cases and polyclonal hypergammaglobulinemia in 7 cases. An acute renal failure was found in all patients with a median creatinin of 520 umol/L. For all patients, the renal echography was normal however, the kidney biopsy showed tubulo-interstitial nephritis. The extra-renal signs highlighting pulmonary interstitial syndrome in 5 cases, a sicca syndrome in 4 cases, mediastinal lymph nodes in 2 cases, a lymphocytic alveolitis in 3 cases, an anterior granulomatous uveitis in 2 cases and a polyarthritis in 5 cases. Five patients benefited of hemodialysis. The treatment consisted of corticosteroid in all cases. The follow up was marked by complete resolution of clinical and biological signs. The diagnosis of renal sarcoidosis must be done quickly to prevent renal failure.

    Pregnancy in women with chronic renal failure is a complex therapeutic problem requiring a multidisciplinary approach. It is associated with a higher risk of many perinatal complications. The most common abnormalities are related to: progression of renal failure, development of preeclampsia development of nephrotic syndrome, anemic syndrome, IUGR and fetal death. The prognosis depends on the values of serum creatinine prior to pregnancy, the degree of deterioration of renal function, development of additional obstetric complications and the specific etiological reasons that have led to the occurrence of renal failure. Determining the optimum time for authorization birth depends on the condition of the mother, the condition of the fetus and the rate of progression of renal failure, and the deadline the pregnancy should be terminated is 35 weeks. We present a case of a patient with chronic renal failure, with favorable perinatal outcome.

    Renal failure secondary to acetaminophen poisoning is rare and occurs in approximately 1-2 % of patients with acetaminophen overdose. The pathophysiology is still being debated, and renal acetaminophen toxicity consists of acute tubular necrosis, without complication if treated promptly. Renal involvement can sometimes occur without prior liver disease, and early renal manifestations usually occur between the 2nd and 7th day after the acute acetaminophen poisoning. While therapy is exclusively symptomatic, sometimes serious metabolic complications can be observed. The monitoring of renal function should therefore be considered as an integral part of the management of children with acute, severe acetaminophen intoxication. We report 3 cases of adolescents who presented with acute renal failure as a result of voluntary drug intoxication with acetaminophen. One of these 3 girls developed severe renal injury without elevated hepatic transaminases. None of the 3 girls' renal function required hemodialysis, but one of the 3 patients had metabolic complications after her acetaminophen poisoning.

    AIM: Clostridium difficile infection is primarily a nosocomial infection but asymptomatic carriers of Clostridium difficile can be found in up to 5% of the general population.Ampicillin, cephalosporins and clindamycin are the antibiotics that are most frequently associated with Clostridium difficile-associated diarrhea or colitis. Little is known about acute renal failure as a consequence of Clostridium difficile-associated diarrhea.METHODS: In this case report, we describe the course of Clostridium difficile-associated diarrhea in an 82-yearold patient developing acute renal failure. Stopping the offending agent and symptomatic therapy brought a rapid improvement of diarrhea and acute renal failure, full recovery was gained 18 d after admission. In a systematic review we looked for links between the two conditions.RESULTS: The link between Clostridium difficilr-associated diarrhea and acute renal failure in our patient was most likely volume depletion. However, in experimental studies a direct influence of Clostridium difficile toxins on renal duct cells could be shown.CONCLUSION: Rapid diagnosis, nonspecific supportive treatment and specific antibiotic treatment, especially in the elderly, may lower excess mortality Clostridium difficile-associated diarrhea and renal failure being possible complications.

  6. Sugammadex in patients with chronic renal failure: two case reports

    Full Text Available Rocuronium is a non-depolarizing aminosteroidal neuromuscular blocking agent that is widely used in general anesthesia. Its effects may be prolonged in patients with renal disease, especially renal failure, due to reduced clearance of the drug. Sugammadex, a modified γ-cyclodextrin, is known to be a highly effective reversal agent for rocuronium-induced muscle relaxation. However, the administration of sugammadex for reversal of rocuronium-induced neuromuscular block in patients with renal disease is controversial. Recently, we administered rocuronium for neuromuscular blockade during the surgery of two patients with chronic renal failure, instead of cisatracurium, a benzylisoquinoline compound. Therefore, we had to administer sugammadex to ensure maximum alleviation of residual neuromuscular blockade risk after surgery. Although the effect of rocuronium was prolonged during surgery, sugammadex quickly and completely restored the response of train-of-four stimulation postoperatively. There were no residual neuromuscular block signs or symptoms observed in these patients throughout the postoperative period. In this report, we share our experience with these cases, and discuss the effectiveness and safety of sugammadex in the context of chronic renal failure.   Keywords: Neuromuscular blockade; Neuromuscular monitoring; Renal failure; Residual neuromuscular blockade; Rocuronium; Sugammadex

    Full Text Available Acute renal failure (ARF in patients with malignancy occurs due to causes such as prerenal, renal and post renal as in normal population. Tumor infiltration of kidneys is usually uncommon. However, renal function may be impaired in fast-growing hematological malignancies such as acute leukemia or lymphoma, depending on tumor involvement. Herein, we presented a case of ARF and later diagnosed as B-cell Non-Hodgkin's lymphoma. 54-year-old male patient was admitted due to ARF. Although development of ARF due to tumor infiltration is rare, in cases who did not have risk factors for development of ARF, leukemic or lymphomatous infiltration should be considered.

    Full Text Available Cutaneous involvement in renal disease is due to a host of factors ranging from metabolic disturbances to immunosuppressive drugs. Herein we report a series of six cases of renal failure with varied cutaneous manifestations ranging from infections to neoplasms due to prolonged immunosuppression. Our first case had cutaneous cryptococcosis where skin lesions gave a clue to the diagnosis of altered sensorium and underlying meningitis. The second case initially presented with florid warts and was treated successfully but later presented with an explosive recurrence of skin lesions due to malignant transformation. Our third case had basal cell carcinoma over the presternal region that was successfully treated with liquid nitrogen cryotherapy. Our fourth case had diabetic nephropathy that presented with septicemia and purpura fulminans. The last case had cutaneous manifestations of drug therapy because of heparin infusion. To conclude, cutaneous manifestations in patients with renal failure are varied and a high degree of suspicion is needed for early diagnosis and aggressive treatment to effectively combat mortality and morbidity.

    We report the case of an 87-year-old white woman with myasthenia gravis who presented with nausea, shortness of breath, azotemia, and hyperkalemia shortly after completing a course of intravenous immunoglobulin (IVIG). She had been receiving monthly transfusions of IVIG, but this time had received daily infusions for 5 days rather than 1 day. She had received this same dose in the past without incident. Her history was significant for coronary artery disease, atrial fibrillation, deep venous thrombosis, pulmonary embolism, chronic steroid use, and recurrent urinary tract infection. On examination, she was slightly confused, mildly dehydrated, had a grade II systolic ejection murmur along the upper left sternal border, had bilateral and symmetric mild weakness of the upper and lower extremities, and exhibited mild edema of the lower extremities. Before transfer from the emergency room, she was found to have an elevated serum urea nitrogen and creatinine of 55 and 5.8 mg/dL (19.6 mmol/L and 512.7 micromol/L, respectively). Creatinine 8 days earlier was 0.9 mg/dL (79.6 micromol/L). The hospital course of the acute renal failure is presented with a review of the literature on cases of acute renal failure after IVIG.

  14. Myoclonus in renal failure: Two cases of gabapentin toxicity

    Directory of Open Access Journals (Sweden)

    Kenneth R. Kaufman

    2014-01-01

    Full Text Available Gabapentin, an AED approved for the adjunctive treatment of partial seizures with/without secondary generalization and for the treatment of postherpetic neuralgia, is frequently used off-label for the treatment of both psychiatric and pain disorders. Since gabapentin is cleared solely by renal excretion, dosing requires consideration of the patient's renal function. Myoclonic activity may occur as a complication of gabapentin toxicity, especially with acute kidney injury or end-stage renal disease. We report 2 cases of myoclonic activity associated with gabapentin toxicity in the setting of renal disease which resolved with discontinuation of gabapentin and treatment with hemodialysis and peritoneal dialysis. As gabapentin has multiple indications and off-label uses, an understanding of myoclonus, neurotoxicity, and renal dosing is important to clinicians in multiple specialties.

    2010-01-01

    Cases of catatonia in patients with renal failure have been rarely reported. In this report, we describe two renal-insufficient patients with catatonia who had a good response to intramuscular lorazepam whereby the catatonic symptoms were relieved. Case 1 involved a patient with end-stage renal disease and severe pneumonia related respiratory failure. He responded well to intramuscular lorazepam (total dose, 4 mg) whereby the catatonia was elieved. Case 2 involved a patient with alcoholic liver cirrhosis and rhabdomyolysis-related acute renal failure. He showed great improvement with intramuscular lorazepam (2 mg) whereby the catatonia was subsequently relieved. This report demonstrates that intramuscular lorazepam is safe, effective and rapid in relieving catatonia associated with renal function impairment. Neither of the patients had a recurrence of catatonia during a period of 6- months follow-up. In conclusion, intramuscular lorazepam may play an important role in the treatment of catatonia associated with renal insufficiency.

    2004-10-01

    An unusual but well-documented presentation of minimal change disease is nephrotic proteinuria and acute renal failure. One pathophysiological mechanism proposed to explain this syndrome is nephrosarca, or severe oedema of the kidney. We describe a patient with minimal change disease who presented with heavy proteinuria and acute renal failure but had no evidence of renal interstitial oedema on biopsy. Aggressive fluid removal did not reverse the acute renal failure. Renal function slowly returned concomitant with resolution of the nephrotic syndrome following corticosteroid therapy. The time profile of the clinical events is not compatible with the nephrosarca hypothesis and suggests an alternative pathophysiological model for the diminished glomerular filtration rate seen in some cases of minimal change disease.

    2014-04-01

    Hypoparathyroidism is an uncommon disease and its coexistence with chronic renal failure is quite rare. Hypocalcemia and hyperphosphatemia are seen in both diseases. Diagnosis of hypoparathyroidism may be overlooked when parathormone response is not evaluated in patients with chronic renal failure. A 19-year-old female patient who had been receiving hemodialysis for 3 years because of chronic renal failure was diagnosed as idiopathic hypoparathyroidism and hashimoto thyroiditis. When her medical records on the first admission and medical history were evaluated, hypoparathyroidism and hashimoto thyroiditis were seen to be present also when she was started hemodialysis. Idiopathic hypoparathyroidism should be suspected in case as absence of parathormone response to hypocalcemia in patients with chronic renal failure. It should be taken into consideration that hashimoto thyroiditis may accompany and required analysis should be done.

    Full Text Available Abstract Introduction Tenofovir is a potent nucleotide analogue reverse-transcriptase inhibitor used with other antiretroviral agents for the treatment of human immunodeficiency virus (HIV infection. Despite the absence of renal toxicity observed in the major clinical trials of tenofovir, several case reports of acute renal failure (ARF and proximal tubule dysfunction have been described. Case presentation We report a patient who developed ARF and Fanconi syndrome during treatment with tenofovir. Despite severe metabolic acidosis associated with a creatinine of 9.8 mg/dL (866 μmol/L, this patient's condition improved on discontinuation of tenofovir treatment without requiring renal replacement therapy. Conclusion Vigilant screening of kidney function is required regularly after initiation of tenofovir due to possible appearance of renal failure.

We retrospectively studied 12 patients presenting with chronic renal failure and brown tumor related to secondary hyperparathyroidism. Eleven patients were on chronic hemodialysis. The median duration between renal failure and end stage renal failure was 36 months (range: 12-190 months and the median duration in dialysis for 11 cases: 92 months (range: 72-252 months. The bone pain was noted in all cases (100%, pathological fracture in one case (8% and a palpable bone tumor in 10 cases (83%. Elevated serum Calcium (> 2.35 mmol/L was noted in four cases (33%, elevated serum Phosphate (> 1.78 mmol/L in ten cases (80%, elevated serum Alkaline Phosphate (> 290 UI/L in all cases and intact PTH was > 300 pg/mL in all cases with a serum median rate at 1475 pg/mL (range: 682-3687 pg/L. Subtotal parathyroidectomy was performed in all cases with a resultant decrease in size of brown tumors. We report here patient with CKD with unusual frequency and variable locations. This may be attributed tothe lack of the new calcium free phosphate binders and calcimimetics.

    Hepatitis A virus is the most common acute viral hepatitis worldwide with approximately 1.5 million cases annually. Hepatitis A virus infection in general is self-limited. In rare cases, hepatitis A virus infection may cause renal failure, hemolytic anemia, and/or cholestasis. We report the first case of acute cholestatic hepatitis A virus infection complicated by hemolytic anemia, and renal failure in one patient. A 42-year-old Caucasian male presented with cholestasis, hemolytic anemia and renal failure after consuming street tacos in Central and South America while on a business trip. His protracted course required corticosteroid therapy, multiple sessions of plasma exchange, and numerous units of packed red blood cells. This case demonstrates the importance of vaccination in high-risk adults. A prompt diagnosis of acute hepatitis A virus infection is essential, as uncommon presentations may delay diagnosis leading to permanent morbidity and potentially death in fulminant cases. We also demonstrate the efficacy of treatment of cholestatic hepatitis A virus infection, hemolytic anemia, and renal failure with corticosteroids and plasma exchange. PMID:25431704

Therefore, he was diagnosed with severe acute liver failure with acute renal failure (ARF) caused by HAV infection. Prognosis was expected to be poor because of complications by ARF and high serum HGF. However, liver and renal functions both improved rapidly without intensive treatment, and he was subsequently discharged from our hospital on the 21(st) hospital day. Although complication with ARF and high levels of serum HGF are both important factors predicting poor prognosis in acute liver failure patients, the present case achieved a favorable outcome. Endogenous HGF might play an important role as a regenerative effector in injured livers and kidneys.

    Dengue is an emerging, rapidly expanding disease, whose clinical and biological manifestations vary. Kidney injury is not usual but can be severe, and it is most often associated with dengue hemorrhagic fever or shock. Guadeloupe, which is located in an endemic area, experienced an epidemic from 2013 to 2014. During this outbreak, a case of renal failure during dengue was observed in a 10-year-old child. No evidence of dengue hemorrhagic fever or shock syndrome was found. The clinical and biological course improved with symptomatic treatment. The association of acute renal failure with hemolytic anemia suggested a diagnosis of hemolytic uremic syndrome. However, this could not be confirmed in the absence of thrombocytopenia and cytopathologic evidence. This case illustrates the diversity of clinical presentations of dengue, and the possibility of severe renal impairment unrelated to the usual factors encountered in dengue.

    Full Text Available Acute renal failure (ARF is a common diagnosis in hospitalized patients, particularly in intensive care units (ICU. Determining the cause and contributing factors associated with ARF is crucial during treatment. The etiology is complex, and several factors often contribute to its development. Medications can cause acute tubular necrosis, acute interstitial nephritis, and crystal-induced or post-obstructive nephropathy. There have been several case reports of ARF secondary to fluoroquinolones. Here we report the development of acute renal failure within a few days of initiating oral ciprofloxacin therapy and briefly describe the different types of renal failure secondary to fluoroquinolone administration. Clinical studies demonstrate that using fluoroquinolones with other potentially nephrotoxic medications requires monitoring of renal function to limit the renal toxicity with these medications. Also, the risk-benefit profile of patients requiring fluoroquinolones should be considered.

    Elizabeth De Francesco Daher

    Full Text Available CONTEXT: Rhabdomyolysis is a severe and life-threatening condition in which skeletal muscle is damaged. Acute renal failure due to rhabdomyolysis has been widely described and its main pathophysiological mechanisms are renal vasoconstriction, intraluminal cast formation and direct myoglobin toxicity. OBJECTIVE: To report on a case of acute renal failure (ARF induced by rhabdomyolysis due to strenuous exercise and alcohol abuse and to describe the pathophysiology of this type of ARF. CASE REPORT: A 39-year-old man arrived at the hospital emergency service with swollen legs and lower extremity compartment syndrome. He was oliguric and had serum creatinine and urea levels of 8.1 mg/dl and 195 mg/dl, respectively. The diagnosis of rhabdomyolysis was made through clinical and laboratory findings (creatine kinase activity of 26320 IU/l. The initial treatment consisted of fluid replacement and forced diuresis. The specific treatment for compartment syndrome, such as fasciotomy, was avoided in order to prevent infection. Partial recovery of renal function was recorded, after ten hemodialysis sessions. Complete recovery was observed after two months of follow-up.

  3. Lactulose and renal failure.

    1997-01-01

    The introduction of lactulose as a new therapeutic agent for treatment of hepatic encephalopathy was a major breakthrough in this field. It was hypothesized that lactulose might prevent postoperative renal impairment after biliary surgery in patients with obstructive jaundice. The presumable mechanism purported was the diminished endotoxinemia by lactulose. Unfortunately, such a reno-protective effect has not been shown conclusively until now in clinical studies. In chronic renal failure lactulose is known to promote fecal excretion of water, sodium, potassium, amonium, urea, creatinine and protons. Thus, lactulose could be useful for the treatment of chronic renal failure. However, compliance to the therapy represents a major problem.

    γ-Butyrolactone (GBL) is a popular drug of abuse which is easily available over the internet. Following a UK classification change to a class C drug in January 2010, internet supply has become difficult. Some of the effects have resulted in sourcing GBL from industrial solvents. We report a case of a 24-year-old man who was admitted for detoxification from GBL. He reported having sourced the GBL by diluting the contents of nail varnish remover pads with water. During his admission he developed a severe withdrawal delirium and acute renal failure. He required admission to the intensive care unit. Physicians and psychiatrists should be aware of toxic sources of GBL leading to renal failure and consider GBL in those presenting with agitation, psychosis or coma.

  5. Perioperative acute renal failure.

    2012-02-03

    PURPOSE OF REVIEW: Recent biochemical evidence increasingly implicates inflammatory mechanisms as precipitants of acute renal failure. In this review, we detail some of these pathways together with potential new therapeutic targets. RECENT FINDINGS: Neutrophil gelatinase-associated lipocalin appears to be a sensitive, specific and reliable biomarker of renal injury, which may be predictive of renal outcome in the perioperative setting. For estimation of glomerular filtration rate, cystatin C is superior to creatinine. No drug is definitively effective at preventing postoperative renal failure. Clinical trials of fenoldopam and atrial natriuretic peptide are, at best, equivocal. As with pharmacological preconditioning of the heart, volatile anaesthetic agents appear to offer a protective effect to the subsequently ischaemic kidney. SUMMARY: Although a greatly improved understanding of the pathophysiology of acute renal failure has offered even more therapeutic targets, the maintenance of intravascular euvolaemia and perfusion pressure is most effective at preventing new postoperative acute renal failure. In the future, strategies targeting renal regeneration after injury will use bone marrow-derived stem cells and growth factors such as insulin-like growth factor-1.

    Full Text Available The annual incidence is about 150 per million in the UK, but this figure is six times greater in the >80 years old group. Prerenal azotemia is considered as the most serious reason in community or hospital acquired acute renal failure (ARF. A 67-year-old middle age male was admitted to the hospital with a chief complaint of generalized weakness, volume depletion and dysuria. He has treated with metronidazole for diarrhoea caused by Clostridium difficile considered as the precipitating factor for the ARF. The patient has severe osteoarthritis and takes high dose non-steroidal anti-inflammatory drugs from the last two years. He also complains for obstructive sleep apnea (OSA and obesity. He has controlled hypertension was on lisinopril to control blood pressure. ARF is quite common, occurring in 80 million populations. Urinary obstruction should be excluded (a cause in around 5-10 of cases because this is readily reversible if it is diagnosed early. A renal US will be sufficient to identify obstruction in 95 of cases. Most cases of ARF are expected to pre renal failure/acute tubular necrosis (ATN 70-80%. Risk factor for development for at ATN are old age, drugs (non-steroidal anti-inflammatory drugs, gentamicin, sepsis, and chronic kidney disease and must be considered.

    Phenazopyridine is a commonly used urinary analgesic available throughout the United States. Ingestion of large quantities can lead to methemoglobinemia, hemolytic anemia, jaundice, and acute renal failure. We report a case of a 78-year-old male with previously normal renal function who developed acute renal failure and jaundice without methemoglobinemia or hyperbilirubinemia after taking nearly 8 g of phenazopyridine over the course of 4 days. Initially presenting with oliguria, the urine output began to increase by day 2 of his admission, and the creatinine peaked 11 days after he began taking phenazopyridine, and he was discharged safely soon after. To our knowledge, this is the first such case of renal failure and jaundice without methemoglobinemia or hemolytic anemia in an adult patient with normal renal function.

    Full Text Available Introduction. Acute renal failure (ARF develops in 33% of the patients with rhabdomyolysis. The main etiologic factors are alcoholism, trauma, exercise overexertion, and drugs. In this report we present a rare case of ARF secondary to probably donepezil-induced rhabdomyolysis. Case Presentation. An 84-year-old male patient was admitted to the emergency department with a complaint of generalized weakness and reduced consciousness for two days. He had a history of Alzheimer’s disease for one year and he had taken donepezil 5 mg daily for two months. The patient’s physical examination revealed apathy, loss of cooperation, and decreased muscle strength. Laboratory studies revealed the following: urea: 128 mg/dL; Creatinine 6.06 mg/dL; creatine kinase: 3613 mg/dL. Donepezil was discontinued and the patient’s renal function tests improved gradually. Conclusion. Rhabdomyolysis-induced acute renal failure may develop secondary to donepezil therapy.

    Rhabdomyolysis caused by cocaine abuse is multifactorial, involving tissue ischemia secondary to vasoconstriction and cellular damage caused by the drug. Renal failure may or may be not associated to rhabdomyolysis. We report a 41-year-old male admitted with a severe rhabdomyolysis after a cocaine overdose. In spite of a vigorous hydration and alkalization, he developed acute renal failure. Renal function recovered after several weeks of dialysis.

    Many chronic renal diseases lead to the final common state of decrease in renal size, parenchymal atrophy, sclerosis and fibrosis. The ultrasound image show a smaller kidney, thinning of the parenchyma and its hyperechogenicity (reflecting sclerosis and fibrosis). The frequency of renal cysts increases with the progression of the disease. Ultrasound generally does not allow for the exact diagnosis of an underlying chronic disease (renal biopsy is usually required), but it can help to determine an irreversible disease, assess prognosis and avoid unnecessary diagnostic or therapeutic procedures. The main exception in which the ultrasound image does not show a smaller kidney with parenchymal atrophy is diabetic nephropathy, the leading cause of chronic and end-stage renal failure in developed countries in recent years. In this case, both renal size and parenchymal thickness are preserved until end-stage renal failure. Doppler study of intrarenal vessels can provide additional information about microvascular and parenchymal lesions, which is helpful in deciding for or against therapeutic intervention and timely planning for optimal renal replacement therapy option.

    Enteropathy-associated T-cell lymphoma (EATCL) is a high grade, pleomorphic peripheral T-cell lymphoma usually with cytotoxic phenotypes. We describe a first case of patient with EATCL that is remarkable for its fulminant course and invasion of both kidneys manifested as acute renal failure. The patient was a 23 year old woman with a long history of celiac disease. She was presented with acute renal failure and enlarged mononuclear infiltrated kidneys. Diagnosis of tubuloi-nterstitial nephritis and polyserositis was confirmed with consecutive pulse doses of steroid therapy. After reco-very, she had disseminated disease two months later. Magnetic resonance imaging showed thickened intestine wall, extremely augmented kidneys, enlarged intra-abdominal lymph nodes with extra-luminal compression of common bile duct. Laparotomy with mesenterial adipous tissue and lymph glands biopsy was done. Consecutive pathophysiological and immunohistochemical analyses confirmed the diagnosis of EATCL: CD45RO+, CD43+,CD3+. The revision of renal pathophysiology sub-stantiated the diagnosis. The patient received chemotherapy,but unfortunately she died manifesting signs of pulmonary embolism caused by tumor cells.

    Bilateral renal vein thrombosis is an unusual etiology of acute renal failure and usually is associated with nephrotic syndrome. We report a 77-year-old man, consulting in the emergency room for anuria that appeared 24 hours after a syncope. The patient was carrier of an inferior vena cava filter prophylactically installed 17 months earlier and was not receiving anticoagulation. Serum creatinine on admission was 5.45 mg/dl and blood urea nitrogen was 54 mg/dl. Computed tomography and Doppler ultrasonography showed an extensive thrombosis of inferior vena cava and both renal veins. Heparin therapy was started with a rapid recovery of renal function and diuresis.

    Miriplatin is a novel lipophilic platinum complex that was developed to treat hepatocellular carcinoma (HCC). Although HCC patients frequently have coexisting chronic renal failure, little prospective data are available regarding the clinical toxicity of chemotherapeutic agents used to treat HCC patients with chronic renal failure. In a phase II study, the plasma concentration of total platinum in patients who received miriplatin was very low, and no severe renal toxicity caused by miriplatin injection was reported. Here, we present three cases of HCC with stage 4 chronic renal failure who received transcatheter arterial chemotherapy with miriplatin. All cases were male, ages 72, 84, and 83 years, and had serum creatinine levels of 2.3, 1.6, and 1.9 mg/dL, respectively. Their estimated glomerular filtration rates were 21.9, 20.3, and 22.2 mL/min, respectively. All cases were treated for unresectable HCC with transcatheter arterial chemotherapy with miriplatin. No serious adverse events were observed, and serum creatinine levels did not elevate, even in the patient who experienced renal failure caused by cisplatin administration. These results might suggest that transcatheter arterial chemotherapy with miriplatin can be safely used in HCC patients with chronic renal failure.

    Renal fluoride toxicity in human beings is difficult to assess in the literature. Although experimental studies and research on methoxyflurane toxicity have shown frank renal damage, observations of renal insufficiency related to chronic fluoride exposure are scarce. We report a case of fluoride intoxication related to potomania of Vichy water, a highly mineralized water containing 8.5 mg/L of fluoride. Features of fluoride osteosclerosis were prominent and end-stage renal failure was present. The young age of the patient, the long duration of high fluoride intake, and the absence of other cause of renal insufficiency suggest a causal relationship between fluoride intoxication and renal failure.

    Renal failure during pregnancy affects both mother and fetus, and may be related to preexisting disease or develop secondary to diseases of pregnancy. Causes include hypovolemia, sepsis, shock, preeclampsia, thrombotic microangiopathies, and renal obstruction. Treatment focuses on supportive measures, while pharmacologic treatment is viewed as second-line therapy, and is more useful in mitigating harmful effects than treating the underlying cause. When supportive measures and pharmacotherapy prove inadequate, dialysis may be required, with the goal being to prolong pregnancy until delivery is feasible. Outcomes and recommendations depend primarily on the underlying cause.

  19. CHRONIC RENAL FAILURE TODAY

    Directory of Open Access Journals (Sweden)

    Svetislav Kostić

    2004-07-01

    Full Text Available The syndrome of chronic renal failure (CRF is already known for more than 150 years. Current research in this domain changed our understanding in epidemiology, aetiology, prevention of disease progression, classifications, definition, and adequate treatment of comorbid conditions in predialytic period. With data collection and registration on CRF patients it is obvious an increase in prevalence and incidence of patients with CRF in the world. The diabetic nephropathy is the most common disease leading in 40% of cases to terminal CRF. In the follow up of these patients the most important goal is slowing down the disease progression with low protein diet (0,6-0,8 g/kg BW/day and vigorous blood pressure control (target values: 120-135/75-85 mmHg. The adequate therapy of anaemia and secondary hyperparathyroidism including predialytic use of erythopoietin and vitamin D significantly slow down the progression of CRF and postpones the beginning of dialytic treatment. Numerous comorbid conditions present in predialytic period fasten the progression of CRF. The most common are of cardiovascular origin (congestive heart failure and coronary artery disease. Those cardiovascular comorbid conditions have an impact on CRF progresion as well as on the outcome in dialytic therapy. The most common causes of cardiovascular comorbidity are hypertension, anemia and secondary hyperparathyroidism, all of which should be treated in predialytic period. Of special concern is use of nephrotoxic drugs, particularly nephrotoxic antibioticsaminoglycosides. The optimal timing of creation of permanent vascular access and vaccination against hepatitis B in predialytic period are cost-effective and have an impact on quality of dialysis.

    Full Text Available It has been hypothesized that chronic renal failure (CRF predisposes patients to infection with intestinal protozoa. We tested this hypothesis with a matched case-control study to determine the prevalence of these protozoa and their diarrhea associated symptoms among 50 patients with CRF (cases from Taif, western Saudi Arabia. Fifty diarrheal patients without CRF were recruited in the study as controls. Participants were interviewed by a structured questionnaire and stool samples were collected. Samples were thoroughly examined with microscopy and three coproantigens detection kits. Enteric protozoa were detected in 21 cases and 14 controls. Blastocystis spp. were the most predominant parasite (16% in cases versus 8% in controls, followed by Giardia duodenalis (10% in cases versus 12% in controls and Cryptosporidium spp. (10% in cases versus 6% in controls. Cyclospora cayetanensis was identified in two cases, while Entamoeba histolytica was described in one case and one control. Intestinal parasitism was positively associated with the male gender, urban residence, and travel history. Clinical symptoms of nausea/vomiting and abdominal pain were significantly varied between the parasitized cases and controls (P value ≤ 0.05. Given the results, we recommend screening all diarrheal feces for intestinal protozoa in the study’s population, particularly those with CRF.

    A 58 year-old woman developed an acute renal failure very quickly after ingestion of two 500 mg tablets of ciprofloxacin, without any other identifiable risk factor. Renal biopsy was performed. No sign of acute interstitial nephritis was observed but tubular lesions were found, accompanied by deposits of a brown-yellowish substance identified by infrared microscopy as a ciprofloxacin salt. The outcome was favourable. This observation gives the opportunity to remind the different forms of quinolone-induced renal injury and to discuss the possible ways for preventing renal side-effects related to the quinolone use.

    2011-11-01

    We report the case of a 55-year-old male with renal failure as the initial manifestation of interstitial and focal infiltration of the kidneys by a small B-cell lymphoma. Since three years, this patient had a history of CLL with plasmocytic differentiation and was left untreated owing to stade A Binet classification. After chemotherapy, the lymphocytosis and the adenopathies disappear and the renal function improve. Infiltration of the kidneys by non-Hodgkin small B-cell lymphoma, including chronic lymphocytic leukaemia (CLL), is usually asymptomatic, fortuitously discovered at the time of an X-ray examination or at autopsy. Association with renal failure is extremely rare. We review the reported cases of renal failure associated with lymphomatous infiltration (13 cases of CLL and five cases of lymphoplasmocytic lymphoma kappa or lambda IgM), with the following conclusions: in most cases, renal insufficiency appears in a few months and significantly disappears after chemotherapy; the renal infiltrate is usually focal in lymphoplasmocytic lymphoma and rather massive and diffuse in CLL; the neoplastic feature of a small B-cell lymphoïd infiltrate may be difficult to determine: a poorly limited, monomorphous, CD20+ CD5+ lymphoid infiltrate is lymphomatous. In case of plasmocytic differentiation, it must be looked for kappa or lambda monotypy; the type of the lymphomatous infiltrate according to the WHO 2008 classification may be difficult to determine in a small sampling of renal tissue: the renal infiltrate must be compared, if possible, with a lymph node infiltrate. Owing to its bad prognosis, mantle cell lymphoma must be distinguished from other small B-cell lymphoma like CLL/small lymphocytic lymphoma, marginal zone lymphoma and lymphoplasmocytic lymphoma.

    2015-07-01

    High-dose antibiotic-loaded bone cement (ALBC) spacers are commonly used to treat prosthetic joint infections following total hip and knee arthroplasties. This methodology can provide high local antibiotic concentrations while minimizing systemic exposure and toxicity. The occurrence of acute kidney injury (AKI) is rarely reported. Available literature suggests that the rate may be higher than previously thought. We report a case of significant systemic tobramycin absorption with concomitant acute renal failure in a 69-year-old female following the implantation of a high-dose ALBC spacer containing both tobramycin and vancomycin. The tobramycin level 24 h post-surgery was 5.8 mcg/mL. Due to concomitant renal failure, antibiotic clearance was poor and resulted in prolonged exposure to elevated aminoglycoside levels. Recovery of renal function occurred, but clinicians should be vigilant in considering the potential impact ALBC spacers can have on post-operative renal function if antibiotic elution is higher than expected.

Case 1: A 57-year-old obese woman in the post-operative period after giant incisional hernia correction with an intra-abdominal pressure of 24 mm Hg. She was sedated and curarized, and the intra-abdominal pressure fell to 15 mm Hg. Case 2: A 73-year-old woman with acute inflammatory abdomen was undergoing exploratory laparotomy when a hypertensive pneumoperitoneum was noticed. During the surgery, enhancement of urinary output was observed. Case 3: An 18-year-old man who underwent hepatectomy and developed coagulopathy and hepatic bleeding that required abdominal packing, developed oliguria with a transvesical intra-abdominal pressure of 22 mm Hg. During reoperation, the compresses were removed with a prompt improvement in urinary flow. Case 4: A 46-year-old man with hepatic cirrhosis was admitted after incisional hernia repair with intra-abdominal pressure of 16 mm Hg. After paracentesis, the intra-abdominal pressure fell to 11 mm Hg.

    We report 3 cases of renal toxicity associated with use of the antiviral agent tenofovir. Renal failure, proximal tubular dysfunction, and nephrogenic diabetes insipidus were observed, and, in 2 cases, renal biopsy revealed severe tubular necrosis with characteristic nuclear changes. Patients receiving tenofovir must be monitored closely for early signs of tubulopathy (glycosuria, acidosis, mild increase in the plasma creatinine level, and proteinuria).

    The woman with complications of chemical abortion (often induced by soap or Lysol solution) is a prototype of the critically ill surgical patient. Usual mortality where hysterectomy is delayed or not done is 60%. 5 such patients, all with sepsis and uterine necrosis were treated by hysterectomy. All had renal failure, 4 required dialysis; 1 underwent diuresis after injection of ethacrynic acid. Major complications, in addition to renal failure, were pulmonary. 2 patients who had prophylactic vena-cava clips and ligation of ovarian veins escaped pulmonary complications. All patients survived without physiologic disturbances.

  8. Acute gouty arthritis and rapidly progressive renal failure as manifestation of multiple myeloma: clinical case description

    2017-09-01

    Full Text Available The article describes a clinical case of multiple myeloma in 78-year-old man, its clinical onset was as an acute attack of gout. The patient was admitted to hospital due to the development of the first acute attack of gout. The attack was characterized by polyarthricular joint lesion of the upper and lower extremities, pronounced inflammatory reaction, insufficient response to the use of non-steroidal anti-inflammatory drugs, and a high level of hyperuricemia. The serum uric acid concentration ranged from 636 to 712 μmol/l. The study of the synovial fluid of the inflamed knee joint made it possible to reveal uric acid crystals and to confirm the diagnosis of acute gouty arthritis. Simultaneously, the patient had significant renal impairment: creatinine was 574 μmol/l, urea — 39.9 mmol/l, glomerular filtration rate according to CKD-EPI — 8 ml/min. The daily proteinuria was 1.8 g. A retrospective assessment of laboratory parameters allowed to reveal completely normal indicators of renal function 6 months ago. Considering the development of acute gouty arthritis, its polyarticular nature, persistent course, rapid involvement of new joints, high uric acid levels during an acute attack exceeding 600 μmol/l (10 mg/dL, rapid development of renal failure within 6 months until the terminal stage, it was suggested the secondary nature of gout on the background of kidney damage by another pathological process. Further clinical, laboratory and instrumental studies allowed verifying multiple myeloma with renal damage. Bence Jones protein in the urine was not detected, there was also no evidence of hyperproteinemia. However, pain in the spine, ribs and chest was the basis for carrying out an X-ray study of the bones of the skeleton. Changes in the skeleton typical for multiple myeloma have been identified. Myelogram showed a high content of plasma cells (21.1 %, electrophoresis of blood proteins showed a high M-gradient (30.42 %, and a cytochemical

    We report a patient with neuroleptic malignant syndrome (NMS) who developed acute renal failure and was successfully treated by hemodialysis. A 60-year-old man with a 26-year history of schizophrenia had been treated with thioridazine and sulpiride. He was admitted to our hospital for muscular rigidity and oliguria. After the diagnosis of NMS with acute renal failure was established, thioridazine and sulpiride were discontinued and hemodialysis was instituted. Renal function gradually improved and hemodialysis was discontinued after 17th treatment. We also reviewed 57 cases of NMS with acute renal failure reported in the literature. To our knowledge, 26 years is the longest latency between initiation of neuroleptic drug treatment and onset of NMS. Our review of reported NMS cases with acute renal failure identified those risks for poor prognosis as high level of BUN, age and female gender.

    Kidney injury associated with lymphocytic leukemia (CLL) is typically caused by direct tumor infiltration which occasionally results in acute renal failure. Glomerular involvement presenting as proteinuria or even nephrotic syndrome is exceptionally rare. Here we report a case of 54-year-old male CLL patient with nephrotic syndrome and renal failure. The lymph node biopsy confirmed that the patients had CLL with remarkable immunoglobulin light chain amyloid deposition. The renal biopsy demonstrated the concurrence of AL amyloidosis and neoplastic infiltration. Combined treatment of fludarabine, cyclophosphamide and rituximab resulted in remission of CLL, as well as the renal disfunction and nephrotic syndrome, without recurrence during a 12-month follow-up. To our knowledge, this is the first case of CLL patient showing the nephrotic syndrome and acute renal failure caused by AL amyloidosis and neoplastic infiltration. Though AL amyloidosis caused by plasma cell dyscrasia usually responses poorly to chemotherapy, this patient exhibited a satisfactory clinical outcome due to successful inhibition of the production of amylodogenic light chains by combined chemotherapy.

    Delusional infestation is an aspecific psychiatric condition manifested either as a primary psychotic disorder or a secondary disorder induced by a wide range of very different medical conditions. Both primary and secondary delusional infestations seem to respond to typical and atypical antipsychotics. The latter are considered the first-line treatment although the use of second-generation antipsychotics featuring a higher metabolic, cardiovascular, and renal tolerability is preferable in secondary cases, which often occur in patients with multiple, severe medical conditions. We report a case of a 72-year-old patient affected by delusional infestation associated with severe renal failure, metabolic syndrome, hypertensive cardiopathy, and chronic cerebrovascular disease.

    Chronic renal failure can give rise to a wide spectrum of oral manifestations, owing mainly to secondary hyperparathyroidism complicating this disease. However, any systemic disease responsible for kidney failure can produce oral manifestations, which can be misdiagnosed. This report describes the case of a 40-year-old male patient referred for oral assessment before kidney and liver transplantation. He had primary hyperoxaluria complicated by end-stage renal failure and secondary hyperparathyroidism. Panoramic radiography indicated not only external root resorption, but also maxillary and mandibular radiolucencies consistent with brown tumors. Unexpectedly, histologic study of the bone biopsy specimen led to the diagnosis of jaws oxalosis. Primary hyperoxaluria is a systemic genetic disease. The affected genes are involved in glyoxylate metabolism and their deficiency results in overproduction of oxalates. Inability of the kidney to excrete oxalates leads to deposition of these crystals in almost all tissues (oxalosis) and to multiple-organ failure. Several oral findings have been described in patients with oxalosis, such as periodontal disease and root resorptions, but radiolucencies in the jaws have rarely been described. This case report is of particular interest because of the unusual location of oxalate crystal deposition in the jaws, which could be misdiagnosed in a patient with renal failure and secondary hyperparathyroidism.

    There is a widening gap between the needs and possibilities of kidney transplantation. In order to solve the problem of organ shortage, the selection criteria for kidney donors have been less stringent over the last years. Favorable outcome of renal transplantation from deceased donors with acute renal failure requiring dialysis may have an important role in expanding the pool of donors. We present the case of two renal transplantations from a polytraumatized 20-years old donor with acute renal failure requiring dialysis. One recipient established good diuresis from the first post-transplant day and did not require hemodialysis. The second recipient had delayed graft function and was treated with 8 hemodialysis sessions. The patient was discharged with good diuresis and normal serum creatinine. After two years of follow-up, both recipients have normal graft function. According to our experience, kidneys from deceased young donors with acute renal failure requiring dialysis may be transplanted, in order to decrease the number of patients on transplantation waiting lists.

  16. A child presenting with acute renal failure secondary to a high dose of indomethacin: a case report

    2009-02-01

    Full Text Available Abstract Introduction Acute renal failure caused by nonsteroidal anti-inflammatory drugs administered at therapeutic doses is generally mild, non-anuric and transitory. There are no publications on indomethacin toxicity secondary to high doses in children. The aim of this article is to describe acute renal failure secondary to a high dose of indomethacin in a child and to review an error in a supervised drug prescription and administration system. Case presentation Due to a medication error, a 20-day-old infant in the postoperative period of surgery for Fallot's tetralogy received a dose of 10 mg/kg of indomethacin, 50 to 100 times higher than the therapeutic dose. The child presented with acute, oligo-anuric renal failure requiring treatment with continuous venovenous renal replacement therapy, achieving complete recovery of renal function with no sequelae. Conclusion In order to reduce medication errors in critically ill children, it is necessary to develop a supervised drug prescription and administration system, with controls at various levels.

  17. ANCA Associated Vasculitis and Renal Failure Related to Propylthiouracil and Hyperthyroidism Induced Cholestasis in the Same Case

    Directory of Open Access Journals (Sweden)

    Mehmet Tuncay

    2014-01-01

    Full Text Available Introduction. Liver involvement due to hyperthyroidism and also ANCA positive vasculitis related renal failure cases were reported separately several times before. However, to our knowledge, these two complications together in the same case had never been observed before. Case Presentation. The case of an ANCA positive 71-year-old Caucasian male with renal failure and lung involvement, subclinical hyperthyroidism, and intrahepatic cholestatic jaundice was presented in this paper. After exclusion of all of the other possibilities, cholestatic hepatitis was explained by subclinical hyperthyroidism; renal failure and lung involvement were interpreted as ANCA related vasculitis which might be a side effect of propylthiouracil use. Conclusion. The coexistence of these rare conditions in the same patient deserves emphasis and it is worth reporting. This case demonstrates that following the clinical course of the patient is essential after prescribing any medications to see whether any complication occurs or not. If the complications of this case were noticed earlier, it would be possible to treat and to prevent the permanent damages.

    A 63-year-old man was admitted to our hospital for evaluation of generalized edema. Coexistence of severe hypothyroidism and nephrotic syndrome was detected by laboratory examination. High titer of both antimicrosomal antibody and antithyroid peroxidase antibody indicated Hashimotoâs disease. Renal biopsy showed minimal change glomerular abnormality, but no findings of membranous nephropathy. A series of medical treatments, including steroid therapy, thyroid hormone and human albumin replacement therapy, were administered. However, acute renal failure accompanied by hypotension, was not sufficiently prevented. After 9 sessions of plasmapheresis therapy, the severe proteinuria and low serum albumin levels were improved. Even after resting hypotension was normalized, neither renal function nor thyroid function were fully recovered. After discharge, renal function gradually returned to normal, and the blood pressure developed into a hypertensive state concomitant with the normalization of thyroid function. This report is a rare case of autoimmune thyroid disease complicated with minimal change nephrotic syndrome. In most cases of nephritic syndrome, acute renal failure (ARF) has been reported to coexist with hypertension. Although pseudohypothyroidism is well-known in nephrotic pathophysiology, complications of actual hypothyroidism are uncommon. It is suggested that the development of hypotension and ARF could be enhanced not only by hypoproteinemia, but also by severe hypothyroidism.

    Due to a combination of ingested ethanol and inhaled trichloroethylene (Tri) a 28 year old man developed toxic hepatitis and acute oliguric renal failure, both of which had a favorable evolution. Tri has been described as a cause of hepatic disfunction and acute renal failure due to acute tubular necrosis, although some of the cases described are controversial, because Tri was either contaminated by other dissolvents or could not be proven pure, with the exception of one case. In many there was ethanol ingestion. The Tri inhaled by our patient was found to contain less than 1% of carbon tetrachloride (C-Tchl). This would suggest the C-Tchl to be responsible for the clinical picture although the combination Tri/ethanol cannot be discarded as the causal agent, due to the small amount of contaminant present.

    Full Text Available Abstract Introduction Group B streptococci are a well-known cause of early and late onset sepsis. In neonates and older children gram-negative bacteria are mostly found in urinary tract infections and urosepsis. In adults predisposing factors for group B streptococci urinary tract infection may include diabetes mellitus and chronic renal failure. Case presentation We present a rare case of a five-month-old Caucasian boy with ultra late onset urosepsis and acute renal failure caused by group B streptococci serotype V. Excretion urography showed a subvesical obstruction that consequently was surgically corrected after antibiotic treatment of the acute infection. Conclusions Group B streptococci serotype V, urogenitary tract malformations, previous hospitalization and medical interventions may be important risk factors for the development of ultra late onset Group B streptococci sepsis in non-neonates.

  1. Nutrition in acute renal failure

    Directory of Open Access Journals (Sweden)

    Sérgio Mussi Guimarães

    Full Text Available Nutritional status has been considered to be one of the possible determinants of mortality rates in cases of acute renal failure (ARF. However, most studies evaluating possible mortality indicators in ARF cases have not focused on the nutritional status, possibly because of the difficulties involved in assessing the nutritional status of critically ill patients. Although the traditional methods for assessing nutritional status are used for ARF patients, they are not the best choice in this population. The use of nutritional support for these patients has produced conflicting results regarding morbidity and mortality. This review covers the mechanisms and indicators of malnutrition in ARF cases and the types of nutritional support that may be used.

    Acute and chronic renal failure secondary to bilateral severe hydroureteronephrosis is a rare sequela of uterine prolapse. We report a case of neglected complete uterine prolapse in a 72-year-old patient resulting in bilateral hydroureter, hydronephrosis, and chronic renal failure. In an attempt to diminish the ureteral obstruction a vaginal pessary was used to reduce the uterine prolapse. Finally, surgical repair of prolapse by means of a vaginal hysterectomy was performed. In conclusion, all patients presenting with complete uterine prolapse should be screened to exclude urinary tract obstruction. If present, obstructive uropathy should be relieved by the reduction or repair of the prolapse before irreversible renal damage occurs.

An aggressive course in immunocompetent healthy patients is unusual. Case presentation We report the case of an immunocompetent 16-year-old Egyptian boy with encephalitis, acute renal failure, and acute hepatitis triggered by viral infection with a complete recovery following antiviral treatment. Conclusion We believe that this case adds to the understanding of the molecular biology, clinical presentation and increasing index of suspicion of many viral infections.

    The efficacy and safety of biologic treatments have been established in patients with moderate to severe psoriasis, but there are few reports on biologic therapy for patients with psoriasis complicated by end-stage renal failure on hemodialysis (HD). In this report, we demonstrated the efficacy and safety of adalimumab for patients with severe psoriasis on HD. A 46-year-old Japanese man with a 14-year history of psoriasis was referred to our clinic in September 2009. He had developed hypertension and renal failure during a 7-year history of cyclosporin treatment. With the infliximab treatment, he achieved 75% improvement of the Psoriasis Area and Severity Index (PASI) score within 3 months from the PASI of 42.3 before the treatment. However, his renal failure gradually deteriorated, and HD was initiated at 1 year after the introduction of infliximab. Because of hydration during the i.v. injection of infliximab, he developed pulmonary edema with every infliximab treatment after starting HD. We switched to ustekinumab treatment, but his psoriasis was not improved. Then, we switched to adalimumab and achieved a PASI-100 response within 2 months. The patient received adalimumab treatment for more than a year without any adverse effects. In addition to our case, five articles reported cases of psoriasis patients with renal failure on HD who were treated with biologics. The psoriatic lesions were improved by biologics in these cases, and no severe adverse effects on the renal function were reported. Thus, biologics are a reasonable treatment option for patients with severe psoriasis with renal failure on HD.

  6. Penile gangrene associated with chronic renal failure - report of 2 cases and review of literature

    2001-01-01

    Full Text Available Penile gangrene associated with chronic renal failure, is a rare entity. Patients usually have associated diseases like diabetes, hypertension. Gangrene occurs because the dystrophic calcific infiltration causes huninal obstruction. This is an accompaniment of generalized soft tissue calcification and bony abnormality resulting. from secondary hyperparathyroidism. Calcium phosphate product exceeds plasma solubility causing precipitation of calcium phosphate. Medical treatment may maintain the product below precipitation levels. Mortality in these patients remains high due to the severity of the associated systemic illnesses. Conservative surgical treatment is advocated in view of short life span.

  7. A complicated case of antepartum eclamptic fit with HELLP syndrome, acute renal failure and multiple intracranial hemorrhages: A mortality report

    2016-04-01

    Full Text Available HELLP is an acronym for hemolysis, elevated liver enzymes and low platelets count, affecting 0.2–12% of all pregnancies or 4–12% of those with preeclampsia. The maternal mortality reported from the literature is up 4% due to disseminated intravascular coagulation, placental abruption, acute renal failure, eclampsia, and cerebral hemorrhage. A 20 year old, G2P1, at 36 weeks of gestation, was referred to our hospital because of postictal coma state with bilateral mydriasis and epistaxis due to repeated antepartum eclamptic fits. Elevated blood pressure level 170/110 mmHg was accompanied with massive proteinuria. Cesarean section was performed and female newborn were delivered. Laboratory findings were characteristic of preeclampsia, HELLP syndrome and renal failure. The patient developed an intraventricular hematoma and an intracerebral hemorrhage with subarachnoid one, which were not suitable to neurosurgical treatment. The patient died from refractory hemolytic anemia, spontaneous bleeding of multiple organs, renal failure and intracranial hemorrhage. Preeclampsia, HELLP syndrome, and acute fatty liver of pregnancy might overlap and be associated with potentially fatal complications, including intracranial hemorrhage, as in the present case. Early detection and diagnosis are crucial to ensure appropriate management and treatment success.

    Full Text Available When we talk about severe malaria, we usually think of Plasmodium falciparum. However, in recent times, Plasmodium vivax has also been reported to cause severe multi-organ dysfunction and life-threatening disease similar to P. falciparum. We report here a case of P. vivax malaria in a young boy from an endemic zone, who developed acute renal failure, severe thrombocytopenia, and anemia and later developed spontaneous subarachnoid hemorrhage. Multisystem involvement in a patient with P. vivax is rare, and subarachnoid hemorrhage is an unusual presentation.

    A 46-year-old man developed neuroleptic malignant syndrome with acute myoglobinuric renal failure after the discontinuation of sulpiride and maprotiline treatment. He showed the characteristic features of hyperpyrexia, altered consciousness, muscle rigidity, and autonomic dysfunction. Laboratory data showed lysis of skeletal muscle cells and renal impairment. Muscle biopsy revealed necrosis and regenerative changes in muscle fibers. Renal biopsy showed focal tubulitis and interstitial infiltration of small inflammatory cells. The combination of sulpiride and maprotiline has not previously been reported to be the cause of neuroleptic malignant syndrome and acute myoglobinuric renal failure.

  10. Bladder rupture causing pseudo acute renal failure

    Full Text Available Bladder rupture is a rare condition associated with significant morbidityand mortality. It is classified into traumatic, nontraumatic or idiopathic andspontaneous. The nonspecific initial clinical presentation is followed bydiscomfort in the lower abdomen, oliguria, hematuria and ascitis. Laboratoryabnormalities simulate the picture of acute renal failure and occurs by amechanism called auto reverse dialysis, with absorption of excreta throughthe peritoneal membrane. The authors describe a case of bladder rupturein morphologically and functionally normal urinary bladder associated withalcohol intake in young healthy man, manifested by abdominal discomfort,pseudo renal failure and massive ascitis. The diagnosis was made by anabdominal multidetector computed tomography confirmed by the finding of7 cm laceration at laparotomy.

    Renal involvement is a common finding in non-Hodgkin's lymphoma (NHL). Acute renal failure at initial presentation due to lymphomatous infiltration of the kidneys has been described infrequently. We report a 17-year-old male who presented with acute renal failure due to massive lymphomatous infiltration of the kidneys, which necessitated hemodialysis. The diagnosis of B-cell NHL was established by tru-cut biopsy of the kidneys and the patient had an excellent response to high-dose chemotherapy with no major complication. The presence of extrarenal involvement in the testes and the retroperitoneal lymph nodes made the diagnosis of primary renal lymphoma debatable. However, considering the delay in diagnosis and the high proliferative rate of B-cell NHL, we might postulate that the disease had originated primarily in the kidneys. We recommend that in NHL cases with severe renal involvement, full-dose chemotherapy should be instituted with meticulous clinical and laboratory follow-up in order to improve clinical and renal failure status rapidly and to avoid further dissemination of NHL.

    Almueilo, Samir H

    2015-01-01

    Renal dysfunction is encountered in 20-25% of patients with multiple myeloma (MM) at the time of diagnosis. There is often a precipitating event. Several biochemical and clinical correlations with renal failure in MM have been reported. Renal failure in MM is associated with worse outcome of the disease. We retrospectively analyzed the medical records of 64 patients with MM admitted to our institution during the period January 1992 to December 2012. Abnormal renal function was observed in 24 (37.5%) patients and 17 (26.6%) of them had renal failure; 14 of the 17 (82.4%) of patients with renal failure had Stage III MM. Urine Bence- Jones protein was positive in ten (58.8%) patients with renal failure versus ten (21.3%) patients without renal failure (P = 0.004). Potential precipitating factors of renal failure were determined in nine patients. Renal function normalized in 11 patients with simple measures, while six patients required hemodialysis; one remained dialysis dependent till time of death. Early mortality occurred in five (29.4%) patients with renal failure as compared with two (4.3%) patients in the group without renal failure (P = 0.005). In conclusion, renal failure is associated with a higher tumor burden and Bence-Jones proteinuria in patients with MM. It is reversible in the majority of patients; however, early mortality tends to be higher in patients with persistent renal failure.

    The prevalence of both hypogonadism and renal failure is increasing. Hypogonadism in men with renal failure carries with it significant morbidity, including anemia and premature cardiovascular disease. It remains unclear whether testosterone therapy can affect the morbidity and mortality associated with renal failure. As such, in this review, we sought to evaluate the current literature addressing hypogonadism and testosterone replacement, specifically in men with renal failure. The articles ...

    The paper briefly summarizes issues related to urinary tract infections in adults: predispositions and risk factors, classification, assessment of pathogenicity of bacterial agents, the role of bacteriuria and leucocyturia, interpretation of findings, treatment principles and an association with chronic renal failure. Urinary tract infections are the second most frequent infectious disease in the population. They most often affect women of childbearing potential and then seniors of both sexes who have multiple risk factors. Escherichia coli and Staphylococcus saprophyticus are the most pathogenic towards urinary tract; they are responsible for 85% and 10-15% of cases of acute uncomplicated urinary infections, respectively. Chronic pyelonephritis, a chronic interstitial nephritis, is the fourth most frequent cause of chronic renal failure. Chronic renal failure is a risk factor for the development of urinary infections due to metabolic disorders resulting in secondary immunodeficiencywith a disorder of all components of immunity. In patients with chronic renal failure, urinary tract infections occur most frequently after kidney transplantation when graft pyelonephritis is a life-threatening complication. Therefore, urinary tract infection prevention with co-trimoxazole once daily over at least 6 months is recommended in renal allograft recipients.

    Full Text Available Introduction: Papillary renal-cell carcinoma, which represents around 20% of renal cell carcinomas, is a heterogeneous disease that includes different tumor types with several clinical and molecular phenotypes. Nivolumab, a fully human IgG4 programmed cell death protein 1 immune checkpoint inhibitor antibody, has shown not only an overall survival advantage when compared to everolimus, but also a relatively good side-effect profile among patients with previously treated advanced or metastatic renal-cell carcinoma. Case report: We describe a case of a young man diagnosed with papillary renal-cell carcinoma that achieved a durable response to nivolumab despite a temporary suspension of the treatment due to a renal function side effect. To our knowledge, it is the first renal failure secondary to nivolumab in a metastatic renal-cell carcinoma patient.Concluding Remarks: Nivolumab is a promising drug in patients with metastatic papillary renal-cell carcinoma and long-term responses can be achieved. In case of acute renal failure secondary to this treatment, temporary therapy suspension and a low dose of systemic corticosteroids can recover renal function without a negative impact on treatment efficacy.

  17. A low-carbohydrate diet may prevent end-stage renal failure in type 2 diabetes. A case report

    2006-06-01

    Full Text Available Abstract An obese patient with type 2 diabetes whose diet was changed from the recommended high-carbohydrate, low-fat type to a low-carbohydrate diet showed a significant reduction in bodyweight, improved glycemic control and a reversal of a six year long decline of renal function. The reversal of the renal function was likely caused by both improved glycemic control and elimination of the patient's obesity. Insulin treatment in type 2 diabetes patients usually leads to weight increase which may cause further injury to the kidney. Although other unknown metabolic mechanisms cannot be excluded, it is likely that the obesity caused by the combination of high-carbohydrate diet and insulin in this case contributed to the patient's deteriorating kidney function. In such patients, where control of bodyweight and hyperglycemia is vital, a trial with a low-carbohydrate diet may be appropriate to avoid the risk of adding obesity-associated renal failure to already failing kidneys.

    Full Text Available The prevalence of both hypogonadism and renal failure is increasing. Hypogonadism in men with renal failure carries with it significant morbidity, including anemia and premature cardiovascular disease. It remains unclear whether testosterone therapy can affect the morbidity and mortality associated with renal failure. As such, in this review, we sought to evaluate the current literature addressing hypogonadism and testosterone replacement, specifically in men with renal failure. The articles chosen for this review were selected by performing a broad search using Pubmed, Embase and Scopus including the terms hypogonadism and renal failure from 1990 to the present. This review is based on both primary sources as well as review articles. Hypogonadism in renal failure has a multifactorial etiology, including co-morbid conditions such as diabetes, hypertension, old age and obesity. Renal failure can lead to decreased luteinizing hormone production and decreased prolactin clearance that could impair testosterone production. Given the increasing prevalence of hypogonadism and the potential morbidity associated with hypogonadism in men with renal failure, careful evaluation of serum testosterone would be valuable. Testosterone replacement therapy should be considered in men with symptomatic hypogonadism and renal failure, and may ameliorate some of the morbidity associated with renal failure. Patients with all stages of renal disease are at an increased risk of hypogonadism that could be associated with significant morbidity. Testosterone replacement therapy may reduce some of the morbidity of renal failure, although it carries risk.

    Acute renal failure (ARF) in a neonate is a serious condition that impacts 8% to 24% of hospitalized neonates. There is a need for prompt evaluation and treatment to avoid additional complications. In this review, a neonate was found to have renal failure associated with renal vein thrombosis. There are varying etiologies of ARF. Causes of ARF are typically divided into three subsets: pre-renal, renal or intrinsic, and post-renal. Treatment of ARF varies based on the cause. Renal vein thrombosis is an interesting cause of renal or intrinsic ARF and can be serious, often leading to a need for dialysis.

    Three dead dogs were brought to the College of Veterinary Medicine, Kyungpook National University for study. Clinically, all the dogs showed emaciation, anorexia, depression, hemorrhagic vomiting and diarrhea for 7-10 days before death. All the clinical signs were first noted for about one month after feeding the dogs with commercial diets. At necropsy, all 3 dogs had severe renal damage with the same green-yellowish colored nephroliths in the renal pelvis. They also showed systemic hemorrhage and calcification of several organs, which might have been induced by uremia. Microscopically, necrosis, calcification and calculi were detected in the renal tubules, and especially in the proximal convoluted tubules and collecting ducts of the kidney. These findings were supportive of a mycotoxic effect, and especially on their kidneys. However, the precise cause of the toxic effect in these cases of canine renal failure could not be determined.

    Full Text Available Gastrointestinal (GI hemorrhage is a frequent and sometimes life-threatening complication of end-stage renal failure. Angiodysplasia (AD, vascular malformation, is the most common cause of recurrent lower-intestinal hemorrhage in patients with renal failure. We report four chronic hemodialysis patients with AD. All patients presented with severe anemia requiring transfusion. GI hemorrhage ceased spontaneously in three cases and after treatment with argon plasma coagulation in another. Diagnosis of AD is usually challenging, since its cause is still unknown, and its clinical presentation is variable. Lesions are multiple in 40-75% of cases, often located in the stomach and duodenum but can affect the colon and the jejunum. Diagnosis is improved by endoscopy which has a much higher sensitivity compared to angiography. Capsular endoscopy may reveal the hemorrhage site in the small intestine when regular endoscopy fails, and therapeutic intervention usually include argon plasma coagulation.

    There are many reports on pregnancy In chronic renal failure with creatinine (Cr levels ≤ 1.5 mg/dl, but pregnancy is uncommon when the levels are above this limit and specially over 3 mg/dl. It is likely that hormonal abnormalities involving low progesterone and high prolactine levels playa key role. We report on three cases with Cr levels equal to or greater than 6 mg/dl during pregnancy or after delivery. We recommend that Cr levels be determined in the initial follow-up of any woman who wishes to become pregnant.

    Se han publicado numerosos reportes de embarazo en pacientes con insuficiencia renal crónica, con creatinina (Cr ≤ 1.5 mg/dl, pero el embarazo es poco común con niveles de Cr mayores, principalmente ≥: 3 mg/dl. Es probable que los niveles bajos de progesterona o altos de prolactina jueguen un papel clave aquí. Publicamos tres casos con Cr ≥: 6 mg/dl durante el embarazo o el postparto. Recomendamos que en toda mujer embarazada o que planee embarazarse se determine la Cr.

    Doxylamine succinate is an antihistaminic drugwith additional hypnotic, anticholinergic and local anesthetic effects first described in 1948. In Korea and many other countries, it is a common-over-the counter medication frequently involved in overdoses. Clinical symtomatology of doxylamine succinate overdose includes somnolence, coma, seizures, mydriasis, tachycardia, psychosis, and rhabdomyolysis. A serious complication may be rhabdomyolysis with subsequent impairment of renal function and acute renal failure. We report a case of acute renal failure and acute pancreatitis complicating a doxylamine succinate intoxication.

    Coronary artery bypass grafting for patients with ischemic heart disease and hypothyroidism contains many controversies, and chronic renal failure causes perioperative water-electrolyte balance disorders. We experienced a case of unstable angina pectoris combined with hypothyroidism and chronic renal failure successfully treated by off-pump coronary artery bypass grafting (OPCAB). A 68-year-old man with a history of hypothyroidism and chronic renal failure was hospitalized with chest pain. Cardiac catheterisation revealed a 90% stenosis of segment 3, 11 and right ventricular (RV) branch, 75% stenosis of segment 6 and 50% stenosis of segment 5. His thyroid function was normal with orally administered levothyroxine. OPCAB was performed safely with hemodialysis until a day before operation and hemofiltration from a day after operation, and postoperative course was uneventful.

    The neuroleptic malignant syndrome is characterized by hyperpyrexia, muscle rigidity, extrapyramidal motion disorder, vegetative symptoms and mental disorientation. This group of symptoms develops abruptly and may lead to serious complications. One of these complications is the acute renal failure. Permanent muscle rigidity causes the damage of muscle cells which result in myoglobinaemia, myoglobinuria and elevations in muscle related creatine phosphokinase. The authors report the case of a young man who underwent neuroleptic medication because of hebephrenia. During the medication the following symptoms were developed: extrapyramidal symptoms, restlessness, muscle rigidity, high fever. These symptoms eventually lead to acute renal failure caused by rhabdomyolysis (characteristic urine finding, significant elevations in serum creatine phosphokinase). With regards to the neuroleptic malignant syndrome dantrolenum and bromocriptin treatment were applied with the discontinuation of neuroleptic medication. As a part of the complex therapy a massive volumen-supplementing and alkalizing treatment was used but haemodialysis had also become necessary. During the above mentioned treatment symptoms referring to the neuroleptic malignant syndrome resolved and the acute renal failure was cured. The case report calls attention to a specific group of symptoms and the possibilities for prevention and treatment. The above case report is the first observation in Hungary.

    Review of the literature concerning contrast-induced renal dysfunction shows that the currently used agents are remarkably safe with careful patient selection. Clinically apparent kidney failure after their use is essentially nonexistent in those without preexistent renal insufficiency. The incidence rises rapidly in those with azotemia from any cause, however, and diabetic persons with nephropathy are perhaps at special risk. Vigorous volume expansion is possibly effective as a preventive measure and may attenuate adverse effects in those in whom postcontrast dysfunction occurs. New agents are becoming available. It is not yet known if these will prove safer or cost-effective. They have some experimentally demonstrated and theoretical advantages over the presently used agents. 58 references, 1 figure, 2 tables.

    Hospitalizations due to heart failure are increasing steadily despite advances in medicine. Patients hospitalized for worsening heart failure have high mortality in hospital and within the months following discharge. Kidney dysfunction is associated with adverse outcomes in heart failure patients. Recent evidence suggests that both deterioration in kidney function and renal congestion are important prognostic factors in heart failure. Kidney congestion in heart failure results from low cardiac output (forward failure), tubuloglomerular feedback, increased intra-abdominal pressure or increased venous pressure. Regardless of the cause, renal congestion is associated with increased morbidity and mortality in heart failure. The impact on outcomes of renal decongestion strategies that do not compromise renal function should be explored in heart failure. These studies require novel diagnostic markers that identify early renal damage and renal congestion and allow monitoring of treatment responses in order to avoid severe worsening of renal function. In addition, there is an unmet need regarding evidence-based therapeutic management of renal congestion and worsening renal function. In the present review, we summarize the mechanisms, diagnosis, outcomes, prognostic markers and treatment options of renal congestion in heart failure.

    Full Text Available Introduction. Little is known about the effects of volume change by hemodialysis (HD and mechanical stress caused by an anatomical structure being in contact with the left atrium on the progression of atrial remodeling. We experienced a case of atrial tachycardia (AT in a patient who had left atrial (LA scarring at the LA roof and a low-voltage area with slow conduction around the LA scar as components of AT circuit. Here, we present the conceivable hypothesis of the LA scar and the low-voltage area formation. Our concept can be useful in developing a strategy for ablation in a patient with chronic renal failure (CRF on HD. Case Report. A 65-year-old man with CRF on HD was referred for AT ablation. Three-dimensional electroanatomical mapping revealed that the AT conducted around an LA scar in a counterclockwise fashion. There was a slow conduction area at the superior side of the LA scar, where the AT was terminated during the ablation. Computed tomography indicated a close relationship between the LA and the anatomical structures (ascending aorta and pulmonary artery. Conclusion. Volume change by HD and close contact of anatomical structures to the LA can promote atrial remodeling, resulting in AT occurrence.

    Full Text Available BACKGROUND The kidney and the skin are the two large networks of the body with abundant blood supply associated with various cutaneous manifestations. This study aims to detect the various cutaneous manifestations and its incidence in patients with chronic renal failure and renal transplantation. MATERIALS AND METHODS This study was done for a period of 1 year from January 2016 to December 2016 at Nephrology OPD ward and Medicine wards, Government KAPV Medical College Hospital, Trichy. During this period, 100 patients who had the presence of skin manifestations were selected and studied (80 renal failure patients and 20 renal transplantation patients. RESULTS Most of the specific cutaneous manifestations of chronic renal failure and renal transplantation were noted in this study. Pruritus and xerosis were the most common manifestations noted in chronic renal failure while infections was commonly noted in renal transplantation patients. CONCLUSION Pruritus and xerosis were the most common among the specific cutaneous manifestations in chronic renal failure followed by nail abnormalities and pigmentary changes. Cutaneous manifestations of renal transplantation were mostly due to infections of which fungal infection is the most common followed by viral infection.

    Full Text Available Malaria has protean clinical manifestations and renal complications, particularly acute renal failure that could be life threatening. To evaluate the incidence, clinical profile, out-come and predictors of mortality in patients with malarial acute renal failure, we retrospectively studied the last two years records of malaria induced acute renal failure in patients with peripheral smear positive for malarial parasites. One hundred (10.4% (63 males, 37 females malaria induced acute renal failure amongst 958 cases of acute renal failure were evaluated. Plasmodium (P. falciparum was reported in 85%, P. vivax in 2%, and both in 13% patients. The mean serum creatinine was 9.2 ± 4.2 mg%, and oligo/anuria was present in 82%; 78% of the patients required hemodialysis. Sixty four percent of the patients recovered completely, 10% incompletely, and 5% developed chronic kidney failure; mortality occurred in 21% of the patients. Low hemoglobin, oligo/anuria on admission, hyperbilirubinemia, cerebral malaria, disseminated intravascular coa-gulation, and high serum creatinine were the main predictors of mortality. We conclude that ma-laria is associated with acute renal failure, which occurs most commonly in plasmodium falci-parum infected patients. Early diagnosis and prompt dialysis with supportive management can reduce morality and enhance recovery of renal function.

    2016-04-01

    Full Text Available Acute renal failure is a frequent cause of morbidity and mortality in emergency, hospitalization and critical care services. In 15 % of cases it is due to rhabdomyolysis, in which there is breakdown of skeletal muscle with massive necrosis and leakage of muscle cell contents into the circulation. It has many different etiologies. The rhabdomyolysis-induced acute kidney injury results from the combination of several mechanisms, including tubular obstruction, vasoconstriction and oxidative stress. The most important therapeutic measures are: Aggressive repletion of fluids, forced diuresis and avoidance of exposure to nephrotoxic substances. In cases of severe uremia, metabolic acidosis, hiperkalemia or fluid overload it is necessary to start renal replacement therapy. As a rule, kidney function is completely recovered, but these patients have higher risk of future chronic kidney disease.

RESULT The number of cases in each grade of CRF were mild 80 (26.67%, moderate 84 (28%, severe 75 (25%, end stage renal disease 61 (20.33%. In all the groups the commonest cause of CRF were Hypertension (HTN 123 out of 300(41% and diabetes 98(32.67%. The commonest ocular symptoms in CRF was blurring of vision 68%. CONCLUSION Many important ocular findings like vitreous haemorrage, retinal detachment, neovascular glaucoma and cataract are the presentation in chronic renal failure, which can cause marked vision loss. Hence proper awareness should be provided to the people in time to prevent these ocular complications.DOI: http://dx.doi.org/10.3126/jcmsn.v10i2.12949 Journal of College of Medical Sciences-Nepal, 2014, Vol.10(2; 18-26

    Together with the prolongation and improving the quality of life of young women with chronic renal failure (CRF), procreation becomes an important issue. Pregnancies in women on renal replacement therapy are associated with an increased risk of health complications, both for mothers and for fetuses. Medical management of pregnant women with CRF is a great challenge and requires a close co-operation of nephrologists, transplantologists, gynecologists and neonatologists. The complexity of problems in these particular pregnancies has urged us to describe the case of a woman with CRF who successfully delivered two babies. We also review the current state of knowledge on the topic. The first pregnancy five years after renal transplantation, was completed with the delivery of term newborn with Tetralogy of Fallot. Also the second pregnancy on hemodialysis therapy was finished by the birth of a healthy neonate at term. The described case indicates that the gynecologists should be prepared for the challenge of the care for pregnancies in women suffering from chronic renal failure on renal replacement therapy.

    AIM: To evaluate the possibility of an association between polyethylene glycol (PEG) and acute renal failure (ARF) in elderly patients using a health insurance claims database.METHODS: We conducted a population-based casecrossover study using information obtained from Korean Health Insurance Review and Assessment Service (HIRA)claims from January 1, 2005 to December 31, 2005(Seoul, Korea). The study population consisted of elderly patients who received PEG prior to experiencing their first ARF-related hospitalization from April 1, 2005 to December 31, 2005. For each patient, one case and two control periods were matched. PEG use in a 2- or 4-wk window period prior to hospitalization for ARF was compared with PEG use in two earlier 2- or 4-wk control window periods. Conditional logistic regression analysis was used to estimate odds ratios (ORs) and 95% CI, adjusting for concomitant uses of diuretics, angiotensin converting enzyme inhibitors, non-steroidal anti-inflammatory drugs,antibiotics, anti-cancer drugs, and contrast media.RESULTS: Within the HIRA database which contained 1 093 262 elderly patients, 1156 hospitalized ARF cases were identified. Among these cases, PEG was prescribed to 17 (1.5%) patients before hospitalization. The adjusted ORs when applying the 2- and 4-wk window periods were 0.4 (95% CI: 0.03-5.24) and 2.1 (95% CI:0.16-27.78), respectively.CONCLUSION: No increased risk of ARF was found in elderly PEG users. However, based on the limited number of study subjects, further analysis should be performed to confirm these results.

    There is a paucity of information about the epidemiology of acute renal failure in Chile. To perform a prospective multicentric survey of severe acute renal failure in Chile. All patients admitted to ten hospitals in Metropolitan Santiago, during a period of six months with severe acute renal failure, were studied. The criteria for severity was the requirement of renal replacement therapy. All patients information was gathered in special forms and the type of renal replacement therapy and evolution was registeres. One hundred fourteen patients were studied (65 males, age range 18 to 87 years). The calculated incidence of acute renal failure was 1.03 cases per 1000 hospital discharges. The onset was nosocomial in 79 subjects (69%) and community acquired in the rest. Renal failure was oliguric in 64 cases (56%) and in 60% of patients it had two or more causative factors. Sepsis, isolated or combined with other causes, was present in 51 of patients. Other causes included ischemia in 47%, surgery in 26%, exogenous toxicity in 25%, endocenous toxicity in 11%, acute glomerular damage in 6% and obstructive uropathy in 6%. Cardiac surgery was responsible for 47% of post operative cases of acute renal failure. Intermittent conventional hemodialysis, continuous renal replacement techniques and daily prolonged hemodialysis were used in 66%, 29% and 2% of patients, respectively. Overall mortality was 45% and it was higher in oliguric patients. Gender, age, cause or the type of therapy did not influence survival. Nine percent of surviving patients had some degree of kidney dysfunction at discharge. There is still a great space for prevention of severe acute renal failure in Chile, considering the main etiologies found in this study.

  6. Rapid improvement in renal function in patients with multiple myeloma and renal failure treated with bortezomib

    Full Text Available Multiple Myeloma (MM frequently presents with renal dysfunction apart from other manifestations. Development of renal failure in patients with MM carries a poor prognosis. Bortezo-mib is a new addition to drugs used in MM and has shown good efficacy and safety profiles. Previous trials have shown its efficacy in relapsed and refractory MM as well. Studies have also shown that bortezomib is also effective in patients with MM who present with renal failure. We report here six cases of renal failure secondary to MM treated with bortezomib. All patients had poor performance status of 3-4 on ECOG scale. Five out of six patients showed satisfactory anti-myeloma response to bortezomib. Reversal of renal failure was observed in all six patients. Adverse effects to bortezomib were mild and manageable. Reversal of renal failure persisted despite incomplete response to MM in two cases, and progression of disease in one patient. It appears that bortezomib may have an effect on the kidneys in reversal of renal failure, other than its anti-myeloma effect. In conclusion, borte-zomib appears to be an effective treatment for patients with advanced MM and renal failure irres-pective of performance status and age.

    Renal replacement therapy became a common clinical tool to treat patients with severe acute kidney injury (AKI) since the 1960s. During this time dialytic options have expanded considerably; biocompatible membranes, bicarbonate dialysate and dialysis machines with volumetric ultrafiltration control have improved the treatment for acute kidney injury. Along with advances in methods of intermittent hemodialysis, continuous renal replacement therapies have gained widespread acceptance in the treatment of dialysis-requiring AKI. However, many of the fundamental aspects of the renal replacement treatment such as indication, timing of dialytic intervention, and choice of dialysis modality are still controversial and may influence AKI patient's outcomes. This review outlines current concepts in the use of dialysis techniques for AKI and suggests an approach for selecting the optimal method of renal replacement therapy.

    1993-01-01

    Ischemic and toxic acute renal failure is reversible, due to the ability of renal tubule cells to regenerate and differentiate into a fully functional lining epithelium. Recent data support the thesis that recruitment or activation of macrophages to the area of injury results in local release of growth factors to promote regenerative repair. Because of intrinsic delay in the recruitment of inflammatory cells, the exogenous administration of growth promoters early in the repair phase of acute renal failure enhances renal tubule cell regeneration and accelerates renal functional recovery in animal models of acute renal failure. Molecular therapy for the acceleration of tissue repair in this disease process may be developed in the near future.

    Multiple tumor-like ectopic calcifications is a rare syndrome characterized by subcutaneous mass deposits of calcium phosphate in periarticular tissues. Although several cases of the surgical treatment of tumoral calcinosis have been reported, the present case is unique in that multiple ectopic calcifications in subcutaneous tissues were found in a hemodialysis patient who had been operated on a total of five times within a period of 1.5 years. A hemodialysis 60-year-old male presented with multiple tumor-like ectopic calcifications bilateral in the shoulders, right buttock and right thigh. He had been operated on a total of five times within a period of 1.5 years; the operations included a subtotal parathyroidectomy with parathyroid autotransplantation in the right forearm. Complete excisions of the ectopic calcifications were performed in the left shoulder, right buttock and right thigh, without signs of recurrence in the same sites at follow-up. Incomplete excision of the ectopic calcification in the right shoulder resulted in recurrence in the same site, and the patient was operated on two more times 1.5 years following the initial surgery. Subtotal parathyroidectomy with parathyroid autotransplantation decreased serum levels of PTH, but the levels of serum calcium and phosphorus remained unchanged post-surgery, which appeared not to inhibit the recurrence of ectopic calcification in patients with CRF. If conservative therapy failed, then early and complete surgical excision may be a good therapeutic option. Copyright © 2016 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    Burn care providers are usually challenged by multiple complications during the management of acute burns. One of the most common complications worldwide is renal failure. This article reviews the various aspects of renal failure management in burn patients. Two different types of renal failures develop in these patients. The different aetiological factors, incidence, suspected prognosis, ways of diagnosing, as well as prevention methods, and the most accepted treatment modalities are all discussed. A good understanding and an effective assessment of the problem help to reduce both morbidity and mortality in burn management.

  13. Diagnosing vascular causes of renal failure.

    Science.gov (United States)

    Abuelo, J G

    1995-10-15

    The incidence of renal failure due to vascular diseases is increasing. Two reasons for this are the epidemic of atherosclerotic vascular disease in the aging population and the widespread use of vasoactive drugs that can adversely affect renal function. These vascular causes of renal failure include vasomotor disorders such as that associated with nonsteroidal antiinflammatory drugs, small-vessel diseases such as cholesterol crystal embolization, and large-vessel diseases such as renal artery stenosis. These causes of azotemia are less familiar to physicians than more classic causes, such as acute tubular necrosis, and are less likely to be recognized in their early stages. This article describes the various vascular diseases that impair renal function and outlines the steps necessary to identify them. Although some of these conditions, such as renal artery stenosis, can gradually impair function, the vascular causes of acute renal failure are emphasized in this article. Because the vasculitides primarily cause renal failure through secondary glomerulonephritis, they are mentioned only briefly. Extensive testing is rarely necessary because the cause is usually suspected through syndrome recognition. The diagnosis can then be confirmed by the results of one or two additional tests or by improved renal function after treatment.

    Lesch-Nyhan syndrome is an X-linked recessive inborn error of purine metabolism, due to deficiency of the enzyme HPRT (hypoxanthine-guanine phosphoribosyl transferase) and underlying HPRT gene mutations (over 300 mutations identified up to date). It is characterized by a wide range of neurological symptoms and signs (mainly a combination of spastic diplegia with choreoathetosis and an overall psychomotor redardation). Herein, we report of two cousins with Lesch-Nyhan syndrome and a confirmed novel HPRT gene mutation: c.65T>C, who both developed nephrocalcinosis and renal failure, findings not been previously published in children with HPRT deficiency.

In this report, we would introduce a 77-year-old woman who was diagnosed as C1q nephropathy by means of electron microscopic and immunofluorescence examination. Facial and lower extremity edema was the main reason for her to go for medical treatment, and she developed into acute renal failure within 5 d. Complete remission was observed after hemodialysis and steroid drugs treatments.

    Guaifenesin is a common nonprescription medication that has been implicated in drug-induced nephrolithiasis. Dextromethorphan, a nonprescription antitussive found in some guaifenesin-containing preparations, is increasingly recognized as a substance of abuse by many youth and young adults. Renally excreted medications known to have poor solubility in urine have the potential to precipitate when ingested in large quantity, leading to acute obstruction of the ureters and renal failure. We describe the case of a 22-year-old male who developed severe bilateral flank pain, hematuria, and oliguria after an isolated recreational ingestion of guaifenesin and dextromethorphan. The patient was found to have bilateral ureteral obstruction and acute renal failure, suspected to be secondary to precipitation of medication metabolites in the urine. This case highlights the potential for acute renal failure secondary to guaifenesin and dextromethorphan abuse. Copyright © 2014 Elsevier Inc. All rights reserved.

    Sexual dysfunction in end-stage renal disease is a troublesome, multifactorial disorder. Abnormality of the hypothalamo-pituitary-gonadal axis is but one of the causes leading to the impotence and infertility commonly encountered in chronic renal failure. Short of kidney transplantation, no therapy is available. Though infertility is the rule in end-stage renal disease, successful fatherhood and deliveries have occurred on rare occasions.

    We report the first case of acute renal failure with hyperkalemia associated with the recently marketed direct renin inhibitor aliskiren. To optimize blood pressure control, the antihypertensive medication of a 76-year-old hypertensive female patient was changed from the angiotensin II receptor antagonist irbesartan to aliskiren. Spironolactone was continued, as serum creatinine and potassium levels were initially normal. Two weeks later the patient presented with acute oliguric renal failure, symptomatic hyperkalemia and metabolic acidosis, necessitating emergency dialytic treatment. Unrecognized pre-existing renal insufficiency (CKD Stage 2 - 3) and the continuation of spironolactone were identified as predisposing risk factors.

    Acute renal failure (ARF), which is diagnosed in 3.4-20% of newborns, is polyetiological in most cases. We present a newborn with non-oliguric ARF diagnosed in the first day of life, and caused by asphixia, intrauterine infection (IUI) and nephrotoxic effects of metotrexate treatment during pregnancy. Antibiotics, including netilmicin and vankomycin, were given because of IUI and infected central venous catheter. Dosage of drugs was adjusted to renal failure parameters, but monitoring of their serum levels was not available. It could cause augmented acute tubular necrosis and interstitial nephritis. Analysis of ARF risk factors in newborns helps in early diagnosis of renal damage and in prompt implementation of therapy.

    Renal function is one of the most consistent prognostic determinants in heart failure. The prognostic information it provides is independent of the ejection fraction and functional status. This article reviews the various renal function assessment measures, with special emphasis on the fact that the patient's clinical situation and response to the heart failure treatment should be considered for the correct interpretation of the results. Finally, we review the literature on the performance of tubular damage biomarkers.

    2000-05-15

    The most serious forms of acute renal failure (ARF) are nowadays encountered in the intensive care unit (ICU), where up to 25% of new patients are reported to develop ARF. Lethality rates may reach 50 to 90% when the ARF is part of a multiple organ dysfunction syndrome. A multitude of extracorporeal procedures have been introduced into intensive care medicine. Applied with adequate skills and experience, most of these techniques will suffice to replace excretory renal function. However, because of low efficacy arterio-venous procedures (CAVH and CAVHD) have been abandoned for the veno-venous, pump-driven techniques (CVVH and CVVHD). Up to now, there is no consensus whether continuous or intermittent renal replacement therapy is more advantageous. In many cases, oliguric patients with circulatory instability will be treated by CVVH, even though there is no prospective study to show that in terms of outcome continuous treatment is superior to intermittent hemodialysis. It is equally conceivable to treat such patients with daily, prolonged (intermittent) hemodialysis. Apparently, the dose of replacement therapy, be it continuous filtration (36 to 48 l/24 h) or intermittent hemodialysis (daily 3 to 4 h) with a target BUN of less than 50 mg/dl, is more important than the modality of treatment. Moreover, there is good evidence that the use of biocompatible membranes (no complement- or leukocyte activation) is preferable and that with high-volume hemofiltration bicarbonate-containing replacement fluids should be used. However, despite all the technical advances, we firmly believe that the skills and the experience of those physicians and nurses who actually perform renal replacement therapy in the ICU are more important than the modality of treatment applied.

    In spite of recent advances in perioperative management, the risk of neurosurgical intervention for patients with chronic renal failure is still considered too high. In this study, coil embolization for incidental aneurysms in such patients is demonstrated in reference to midterm results. A 42-year-old woman with a history of hemodialisis for 7 years presented with subcortical hemorrhage in her right frontal lobe. The magnetic resonance angiography (MRA) demonstrated a distal anterior cerebral artery aneurysm, but it was considered to be unrelated to the hemorrhage. Two and a half months after the hemorrhage the aneurysm was embolized with interlocking detachable coils. Thirty months after embolization, the angiogram revealed the coil compaction and the recanalization of the aneurysm neck. However, 54 months after embolization, the figure of the embolized aneurysm and neck remnant was the same as the previous findings. A 69-year-old woman with a history of hemodialisis for 5 years suddenly experienced left hemiparesis. Computed tomography revealed cerebral infarction in the right frontoparietal white matter. In addition, a left middle cerebral artery aneurysm was unexpectedly found on the MRA. Five months after the onset of the attack, the aneurysm was embolized with a Guglielmi detachable coli. An angiogram obtained 24 months after the embolization showed the aneurysm to be almost completely obliterated. In considering the therapeutic risks and benefits for incidental aneurysms of patients with chronic renal failure, intra-vascular surgery could be recommended as a less invasive treatment.

    A previously healthy young man presented with acute renal failure due to extensive spontaneous deep vein thrombosis, including the inferior vena cava (IVC) and both renal veins. The patient was treated with selectively delivered thrombolytic therapy over a 7-day-period, which resulted in renal vein patency and complete recovery of renal function. A stent was placed over a segment stenosis of the IVC. No thrombophilic factors were identified. Bilateral renal vein thrombosis in young fit individuals is an unusual cause of acute renal failure. Thrombolytic therapy, even with delay, can completely restore renal function.

    2014-09-01

    Decompensation in heart failure occurs when the heart fails to balance venous return with cardiac output, leading to fluid congestion and contributing to mortality. Decompensated heart failure can cause acute kidney injury (AKI), which further increases mortality. Heart failure activates signaling systems that are deleterious to kidneys such as renal sympathetic nerve activity (RSNA), renin-angiotensin-aldosterone system, and vasopressin secretion. All three reduce renal blood flow (RBF) and increase tubular sodium reabsorption, which may increase renal oxygen consumption causing AKI through renal tissue hypoxia. Vasopressin contributes to venous congestion through aquaporin-mediated water retention. Additional water retention may be mediated through vasopressin-induced medullary urea transport and hyaluronan but needs further study. In addition, there are several systems that could protect the kidneys and reduce fluid retention such as natriuretic peptides, prostaglandins, and nitric oxide. However, the effect of natriuretic peptides and nitric oxide are blunted in decompensation, partly due to oxidative stress. This review considers how neurohormonal signaling in heart failure drives fluid retention by the kidneys and thus exacerbates decompensation. It further identifies areas where there is limited data, such as signaling systems 20-HETE, purines, endothelin, the role of renal water retention mechanisms for congestion, and renal hypoxia in AKI during heart failure.

    The causes of malnutrition in chronic terminal kidney failure are reviewed in the situation both before and after dialysis, as are the malnutrition rates in both circumstances and their treatment. Malnutrition has a high prevalence in terminal kidney patients, partly as a result of the therapeutic restriction on calories and proteins, but also due to the metabolic reactions typical of the disease and to anorexia. In patients subjected to dialytical methods, certain other mechanisms are added. In addition to malnutrition, there are alterations in the metabolism of calcium, phosphorus and potassium, as well as lipids, thus limiting nutritional therapy's ability to restore the nutritional status to normal. An awareness of energy expenditure in chronic terminal kidney failure and the consequences of malnutrition have led to new challenges in nutritional therapy, both in the dose and quality of the proteins, with a debate raging over the advantages of ketoanalogues, and also in the methods for providing nutrients. The ideal nutritional method for repletion is oral administration, but this can be enhanced with artificial support such as oral supplements, parenteral nutrition during dialysis or such alternatives as enteral nutrition at home in the case of chronic kidney problems in children, using percutaneous endoscopic gastrostomy (PEG), in order to nourish the patients and minimize growth disorders.

  11. Malignancy and chronic renal failure.

    Science.gov (United States)

    Peces, Ramon

    2003-01-01

    Increased incidence of cancer at various sites is observed in patients with end-stage renal disease (ESRD). Certain malignant diseases, such as lymphomas and carcinomas of the kidney, prostate, liver and uterus, show an enhanced prevalence compared with the general population. In particular, renal cell carcinoma (RCC) shows an excess incidence in ESRD patients. A multitude of factors, directly or indirectly associated with the renal disease and the treatment regimens, may contribute to the increased tumor formation in these patients. Patients undergoing renal replacement therapy (RRT) are prone to develop acquired cystic kidney disease (ACKD), which may subsequently lead to the development of RCC. In pre-dialysis patients with coexistent renal disease, as in dialysis and transplant patients, the presence of ACKD may predispose to RCC. Previous use of cytotoxic drugs (eg, cyclophosphamide) or a history of analgesic abuse, are additional risk factors for malignancy. Malignancy following renal transplantation is an important medical problem during the follow-up. The most common malignancies are lymphoproliferative disorders (early after transplantation) and skin carcinomas (late after transplantation). Another important confounder for risk of malignancy after renal transplantation is the type of immunosuppression. The type of malignancy is different in various countries and dependent on genetic and environmental factors. Finally, previous cancer treatment in a uremic patient on the transplant waiting list is of great importance in relation to waiting time and post-malignancy screening.

    Spontaneous ruptures of the quadriceps tendon are infrequent injuries, it is seen primarily in patients with predisposing diseases such as gout, rheumatoid arthritis and chronic renal failure. A 32-year-old man had a history of end stage renal disease and received regular hemodialysis treatment for more than 5 years. He was admitted in our service for total functional impotence of the right lower limb with knee pain after a common fall two months ago. The radiogram showed a ''patella baja" with suprapatellar calcifications. The ultrasound and MRI showed an aspect of rupture of the quadriceps tendon in its proximal end with retraction of 3 cm. Quadriceps tendon repair was performed with a lengthening plasty, and the result was satisfactory after a serial rehabilitation program. The diagnosis of quadriceps tendon ruptures needs more attention in patients with predisposing diseases. They should not be unknown because the treatment of neglected lesions is more difficult. We insist on the early surgical repair associated with early rehabilitation that can guarantee recovery of good active extension.

    Cardiotoxicity is an emerging concern with a new class of drugs known as targeted agents, which include trastuzumab and sunitinib. Sunitinib is a small molecule that inhibits multiple tyrosine kinase receptors. This drug was approved by the United States Food and Drug Administration in 2006 for the treatment of clear cell metastatic renal cell carcinoma and advanced gastrointestinal stromal tumors. We describe a 65-year-old woman who was treated with sunitinib for metastatic clear cell renal cell carcinoma. After 5 months of therapy, she developed acute heart failure requiring hospitalization; sunitinib was immediately discontinued. The patient had classic symptoms of heart failure, including pleural effusion. An echocardiogram revealed a left ventricular ejection fraction of 30%. She received standard treatment for heart failure, including a beta-blocker, an angiotensin-converting enzyme inhibitor, and diuretics. Within 1 month, the patient's symptoms resolved, and subsequent cardiac evaluation showed that her left ventricular ejection fraction returned to normal. According to the Common Terminology Criteria for Adverse Events developed by the National Cancer Institute, her cardiac event associated with sunitinib was defined as grade III toxicity. One month later, sorafenib, another tyrosine kinase inhibitor, was started with the aim of continuing her previous response to sunitinib. After 7 months of sorafenib therapy, the patient had no evidence of heart failure, and her condition was responding to treatment. Clinicians should be aware that sunitinib-induced heart failure occurs occultly and that many--but not all--cases resolve with discontinuation of the drug. Use of sorafenib after sunitinib-induced heart failure appears to be safe and effective, which suggests that cardiotoxicity is not a general class effect of the tyrosine kinase inhibitors.

    HBV infection in chronic renal failure (CRF) becomes chronic in 30 to 60% compared with less than 10% in nonuremic patients. Immunological dysfunction in patients on hemodialysis may be related to imbalanced cytokine systems, such as tumor necrosis factor (TNF-|α|) and interleukin (IL) 6,1 by retention of renal metabolite in uremia and chronic inflammation and have a poor immunological reaction to T-cell-dependent antigens, like hepatitis B vaccination. Immunocompromised patients who are unre...

    The aim of study was to introduce and evaluate a method for quantifying the parathyroid hormone (PTH) secretion during hemodialysis in secondary hyperparathyroidism due to end-stage renal failure. We developed a method suitable for inducing sequential hypocalcemia and hypercalcemia during....../ionized calcium curves were constructed, and a mean calcium set-point of 1.16 mmol/liter was estimated compared to the normal mean of about 1.13 mmol/liter. In conclusion, we demonstrate that it is important to use a standardized method to evaluate parathyroid hormone dynamics in chronic renal failure. By the use...... of a standardized method we show that the calcium set-point is normal or slightly elevated, indicating normal parathyroid reactivity to calcium in chronic renal failure....

    Exposure to organic solvents has been suggested to cause or exacerbate renal disease, but methodologic concerns regarding previous studies preclude firm conclusions. We examined the role of organic solvents in a population-based case-control study of early-stage chronic renal failure (CRF). All native Swedish residents aged 18 to 74 yr, living in Sweden between May 1996 and May 1998, formed the source population. Incident cases of CRF in a pre-uremic stage (n = 926) and control subjects (n = 998), randomly selected from the study base, underwent personal interviews that included a detailed occupational history. Expert rating by a certified occupational hygienist was used to assess organic solvent exposure intensity and duration. Relative risks were estimated by odds ratios (OR) in logistic regression models, with adjustment for potentially important covariates. The overall risk for CRF among subjects ever exposed to organic solvents was virtually identical to that among never-exposed (OR, 1.01; 95% confidence interval [CI], 0.81 to 1.25). No dose-response relationships were observed for lifetime cumulative solvent exposure, average dose, or exposure frequency or duration. The absence of association pertained to all subgroups of CRF: glomerulonephritis (OR, 0.96; 95% CI, 0.68 to 1.34), diabetic nephropathy (OR, 1.02; 95% CI, 0.74 to 1.41), renal vascular disease (OR, 1.16; 95% CI, 0.76 to 1.75), and other renal CRF (OR, 0.92; 95% CI, 0.66 to 1.27). The results from a nationwide, population-based study do not support the hypothesis of an adverse effect of organic solvents on CRF development, in general. Detrimental effects from subclasses of solvents or on specific renal diseases cannot be ruled out.

    Although acute renal failure is encountered with administration of nephrotoxic drugs, ischemia, or unilateral nephrectomy, there has been no effective drug which can be used in case of acute renal failure. Hepatocyte growth factor (HGF) is a potent hepatotropic factor for liver regeneration and is known to have mitogenic, motogenic, and morphogenic activities for various epithelial cells, including renal tubular cells. Intravenous injection of recombinant human HGF into mice remarkably suppressed increases in blood urea nitrogen and serum creatinine caused by administration of cisplatin, a widely used antitumor drug, or HgCl_2, thereby indicating that HGF strongly prevented the onset of acute renal dysfunction. Moreover, exogenous HGF stimulated DNA synthesis of renal tubular cells after renal injuries caused by HgCl_2 administration and unilateral nephrectomy and induced reconstruction of the normal renal tissue structure in vivo. Taken together with our previous finding that expression of HGF was rapidly induced after renal injuries, these results allow us to conclude that HGF may be the long-sought renotropic factor for renal regeneration and may prove to be effective treatment for patients with renal dysfunction, especially that caused by cisplatin.

  20. Factors influencing general practitioner referral of patients developing end-stage renal failure: a standardised case-analysis study.

    LENUS (Irish Health Repository)

    Montgomery, Anthony J

    2006-01-01

    BACKGROUND: To understand why treatment referral rates for ESRF are lower in Ireland than in other European countries, an investigation of factors influencing general practitioner referral of patients developing ESRF was conducted. METHOD: Randomly selected general practitioners (N = 51) were interviewed using 32 standardised written patient scenarios to elicit referral strategies. Main outcome measures: General practitioner referral levels and thresholds for patients developing end-stage renal disease; referral routes (nephrologist vs other physicians); influence of patient age, marital status and co-morbidity on referral. RESULTS: Referral levels varied widely with the full range of cases (0-32; median = 15) referred by different doctors after consideration of first laboratory results. Less than half (44%) of cases were referred to a nephrologist. Patient age (40 vs 70 years), marital status, co-morbidity (none vs rheumatoid arthritis) and general practitioner prior specialist renal training (yes or no) did not influence referral rates. Many patients were not referred to a specialist at creatinine levels of 129 micromol\\/l (47% not referred) or 250 micromol\\/l (45%). While all patients were referred at higher levels (350 and 480 micromol\\/l), referral to a nephrologist decreased in likelihood as scenarios became more complex; 28% at 129 micromol\\/l creatinine; 28% at 250 micromol\\/l; 18% at 350 micromol\\/l and 14% at 480 micromol\\/l. Referral levels and routes were not influenced by general practitioner age, sex or practice location. Most general practitioners had little current contact with chronic renal patients (mean number in practice = 0.7, s.d. = 1.3). CONCLUSION: The very divergent management patterns identified highlight the need for guidance to general practitioners on appropriate management of this serious condition.

    Full Text Available Background/Aim. Hemodynamic stress is the leading cause of acute renal failure (ARF in premature neonates. Incidence of ARF in this population is between 8 and 24%. The aim of this study was to determine the frequency of presence of ARF in premature neonates, as well as its impact on their survival. Methods. A retrospective study of 114 premature neonates [(gestational age, GA less than 37 gestation weeks (gw] admitted to the Intensive Care Unit (ICU at the Pediatric Clinic, Institute of Child and Youth Healthcare of Vojvodina in 2007 was conducted. Serum creatinine, urea and bilirubine were determined on the 3rd day of life in 65 newborns who met inclusion criteria. ARF was diagnosed in 16 newborns (n=16/65; 25%. Results. The premature neonates with ARF had significantly lower GA [<28 gw - 8/16 (50% vs. 5/49 (10%; p < 0.05], birth weight (BW (1 265 g vs. 1615 g; p < 0.05 and systolic blood pressure (43.37 mm Hg vs. 52.7 mmHg; p < 0.05 than ones without ARF. Non-olyguric ARF was diagnosed in 62% of newborns with ARF (n=10/16, while the rest had the olyguric type (n = 6/16; 38%. Twenty-five percent of premature neonates with ARF (n = 4/16 died in contrast to 10% of premature neonates without ARF (n = 5/49. ARF was treated conservatively in all but 3 cases when peritoneal dialysis was performed. Renal function has recovered completely in all of the survivors. In order to determine their predictivity in relation to ARF, following parameters were analyzed: GA, BW < 1 500 g, presence of concomitant sepsis and intracranial hemorrhage grade III/IV. BW < 1 500 g demonstrated the highest sensitivity (se 0.75, while GA < 28 gw, sepsis and intracranial hemorrhage grade III/IV showed high specificity (sp = 0.90, 0.89 0.88, respectively. Conclusion. Acute renal failure frequently occurs in population of premature neonates and requires meticulous fluid and electrolyte balance, especially in the case of low birth weight and extreme immaturity.

    2012-07-01

    After broad cardiological and nephrological evaluation and consideration of optimal conservative options according to national and international guidelines, renal replacement therapy might be helpful in patients with refractory heart failure even if they are not dialysis-dependent. This is even more important as renal failure is a strong predictor for mortality in patients with severe congestive heart failure (CHF) and CHF is one of the fastest growing morbidities in western countries. Although peritoneal dialysis (PD) is frequently used in patients with CHF its role remains unclear. Acute chronic volume overload in refractory CHF is still an unresolved clinical problem. In patients with acute heart and renal failure with need of management in an intensive care unit, extracorporeal ultrafiltration or a dialysis modality should be preferred. In patients with chronic refractory CHF, volume overload and renal failure, peritoneal dialysis should be the therapy of choice. Due to the limited data available, treatment and outcome parameters should be recorded in the registry of the German Society of Nephrology (http://www.herz-niere.de).

    We report a case of a 68 year old male who presented with an acute onset of anuric renal failure. Investigations revealed a histologically confirmed “double-positive” anti-GBM disease with initially undetectably high antibody values. An induction therapy with plasma exchange, cyclophosphamide and initially high dose steroids and further maintenance therapy for three months was initiated. The patient remained dialysis-dependent despite partial recovering of renal function. Without pulmonary involvement there were no clues for Goodpasture’s disease. Renal prognosis is unfavourable.

    Full Text Available Renal failure is a serious complication of malaria, with a mortality of 14 to 33%. In view of the significant morbidity and mortality due to acute renal failure in malaria, there is need to identify patients at an early stage and to intensify care given to reduce morbidity and mortality. AIMS  To evaluate the clinical profile of Acute Renal Failure (ARF in malaria.  To evaluate the factors associated with adverse outcome, relation of severity of renal impairment on final outcome in patients with ARF due to malaria. MATERIAL AND METHODS This study was conducted at a tertiary care hospital over a period of 12 months. STUDY DESIGN  Type of study: Prospective Analytical, Observational Study.  Sample Size: 50 patients admitted to ICU, Kidney Unit, and the Medicine Wards with Malaria and ARF. Inclusion Criteria Clinically screened patients with evidence of malarial parasites in the blood smears or by antigen detection with clinical features or biochemical evidence of acute renal failure. Exclusion Criteria  Presence of any disease or condition leading to ARF or affecting the outcome of malarial ARF.  Other causes of Fever, Jaundice and Oliguria, like Leptospirosis, Dengue. METHODOLOGY Fifty patients who fulfilled the inclusion criteria were interrogated with regards to the complaints, clinical signs. Blood tests were sent on admission. Details were recorded as per the clinical proforma. The patients were followed until their discharge/death. RESULTS Oliguria was present in only 30% of patients. 30% of patients received haemodialysis. The mortality was 12% for severe renal failure. On Univariate analysis, Acidosis and Cerebral malaria were highly significant predictors of mortality. Other significant predictors were Renal failure, Oliguria, Shock, DIC, Hyperparasitemia, Leukocytosis (TLC. On Multivariate analysis, Oliguria, Cerebral malaria, Acidosis, Shock and two or more complications were the independent predictors of mortality

    2014-01-01

    Full Text Available Metamizole or dipyrone is a pyrazolone derivative that belongs to the non-steroidal anti-inflammatory drugs. Its main side-effect is hematological toxicity. Thrombocytopenia due to metamizole is rare and is usually associated with the involvement of the two other blood series. Drug-induced thrombocytopenia is more frequently related to immune mechanisms, and the diag-nosis is still largely made by exclusion of other causes and by correlation of timing of thrombocytopenia with the administration of drug. Metamizole may cause acute renal failure due to hemodynamic renal failure/acute tubular necrosis and/or acute tubulointerstitial nephritis. We report a case of acute renal failure and severe thrombocytopenia after metamizole. As far as we know, this combination of adverse effects from this drug has not been reported previously.

    Full Text Available Acute renal failure (ARF is a rare complication of acute pyelonephritis in adult immunocompetent patients. Recovery of renal function usually occurs if antibiotics are promptly initiated. However, long-term consequences of renal scarring due to acute pyelonephritis are probably underestimated, and some patients present with prolonged renal failure despite adequate antibiotic therapy. We report two cases of severe ARF complicating bacterial pyelonephritis successfully treated with corticosteroids in association with conventional antibiotics.

    Endothelial dysfunction is principally characterized by impaired endothelium- dependent transduction mechanisms related to vascular relaxation, as an outcome of decreased release of endothelium-derived relaxing factors, mainly nitric oxide, as well as augmented oxidative stress, increased inflammation and predominance of vascular action produced by endothelium-derived contracting factors. Current data strongly suggest that pathological development of different types of kidney impairment with further progression to renal failure includes notable vascular changes associated with endothelial dysfunction. In accordance, this scientific field represents an advancing area of investigation, involving different biomarkers of endothelial dysfunction linked to renal impairment, as well as clinical findings with new information that can provide a more comprehensive understanding of the role of endothelial dysfunction in kidney disease. With regards to quoted facts, the aim of this article was to review the latest data related to endothelial dysfunction and renal failure by selection of relevant articles released from 2010 to 2015.

    During acute renal injury, there are alterations in the expression of several growth factors and their receptors in the kidney. The increased expression of several growth factors and/or their receptors at sites of nephron injury suggests important contributions to repair. Exogenous administration of some growth factors, such as IGF-I, EGF and HGF, accelerates recovery of renal function in experimental acute renal failure (ARF). In ARF growth factors act through several mechanisms, which may include altered cell cycle regulation and mitogenesis, differentiation of recovered cells, regulation of apoptosis, improved renal hemodynamics, and others. There is evidence for interactions of growth factors with other growth factors as well as with other genes resulting in complex orchestration of biologic events contributing to recovery from ARF.

    Renal sonography is a routine step in the evaluation of new onset renal failure. When renal masses are discovered in this setting, functional imaging may be critical. We report a case of bilateral renal masses in a girl with urinary tract infection and renal insufficiency found to have vesicoureteral reflux. Renal scintigraphy revealed these masses to be the only remaining functional renal tissue, preventing potentially harmful resection. (orig.)

    The acute renal failure is the frequent medical complication observed in liver transplant patients. The objective of this study was to determine the cause of acute renal failure in post liver transplant patients. A total of 70 patients who underwent (cadaveric 52, live 18) liver transplantation were categorized based on clinical presentation into two groups, namely hepatorenal failure (HRF, n = 29), and Hepatic failure (HF, n = 41). All the patients after the liver transplant had received tacrolimus, mycophenolate and steroids. We analyzed the modification of diet in renal disease, (MDRD) serum urea, creatinine and albumin before and after 5th and 30th day of liver transplant and data was categorized into survivors and non-survivors group. In HRF survivor group, serum creatinine, and urea levels were high and, albumin, MDRD were low in pre- transplant and reached to normal levels on 30th day of post transplant, and 79.3 % of patients in this group showed resumption of normal kidney function. On the contrary in HRF nonsurvivor group, we did not observed any significant difference and 20.7 % of patients showed irreversible changes after the liver transplant. In HF survivor group, 82.9 % of liver failure patients did not show any deviation in serum creatinine, urea, albumin and MDRD, whereas in HF non survivor group, 17.1 % of liver failure patients who had HCV positive before the transplant developed acute renal failure. The levels of creatinine, urea, albumin and MDRD were normal before the transplant and on day 30th, the levels of albumin and MDRD were significantly low whereas serum urea, creatinine levels were high. In conclusion, based on these observations, an diagnosis and treatment of Acute renal failure is important among the liver transplantation cases in the early postoperative period.

    Fungal infection of the kidneys is a rare condition that has been reported in premature babies and in diabetic or immunocompromised adult patients. Candida spp. is the most frequent micro-organism involved. This paper reports a case of an immunocompetent newborn with a bladder exstrophy who suffered from an acute renal failure caused by bilateral renal aspergilloma (Aspergillus flavus). The newborn was treated with amphotericin B urinary tract irrigation through bilateral nephrostomy catheters, combined with liposomal amphotericin B and voriconazole therapy, which improved his renal function. However, due to persistent fungal colonization, a long antifungal treatment and permanent ureterostomies were necessary to deal with new episodes of ureterorenal obstruction. As of November 2009, despite the renal injuries, renal function had been conserved. The management of the mechanical obstruction and the choice of antifungal drugs are discussed in this unusual case.

    Full Text Available Abstract Background Condom catheters are indicated in spinal cord injury patients in whom intravesical pressures during storage and voiding are safe. Unmonitored use of penile sheath drainage can lead to serious complications. Case report A 32-year old, male person, sustained complete paraplegia at T-11 level in 1985. He had been using condom catheter. Eleven years after sustaining spinal injury, intravenous urography showed no radio-opaque calculus, normal appearances of kidneys, ureters and bladder. Blood urea and Creatinine were within reference range. A year later, urodynamics revealed detrusor pressure of 100 cm water when detrusor contraction was initiated by suprapubic tapping. This patient was advised intermittent catheterisation and take anti-cholinergic drug orally; but, he wished to continue penile sheath drainage. Nine years later, this patient developed bilateral hydronephrosis and renal failure. Indwelling urethral catheter drainage was established. Five months later, ultrasound examination of urinary tract revealed normal kidneys with no evidence of hydronephrosis. Conclusion Spinal cord injury patients with high intravesical pressure should not have penile sheath drainage as these patients are at risk for developing hydronephrosis and renal failure. Intermittent catheterisation along with antimuscarinic drug should be the preferred option for managing neuropathic bladder.

    Full Text Available Acute renal failure (ARF is defined as a rapid decrease in the glomerular filtration rate, occurring over a period of hours to days. The Science and Technology University Hospital, Sana′a, is a referral hospital that caters to patients from all parts of Yemen. The aim of this study is to have a deeper overview about the epidemiological status of ARF in Yemeni patients and to identify the major causes of ARF in this country. We studied 203 patients with ARF over a period of 24 months. We found that tropical infectious diseases constituted the major causes of ARF, seen in 45.3% of the patients. Malaria was the most important and dominant infectious disease causing ARF. Hypotension secondary to infection or cardiac failure was seen in 28.6% of the patients. Obstructive nephropathy due to urolithiasis or prostate enlargement was the cause of ARF in a small number of patients. ARF was a part of multi-organ failure in 19.7% of the patients, and was accompanied by a high mortality rate. Majority of the patients were managed conservatively, and only 39.9% required dialysis. Our study suggests that early detection of renal failure helps improve the outcome and return of renal function to normal. Mortality was high in patients with malaria and in those with associated hepatocellular failure.

    The prevalence of chronic renal failure (CRF) at the time of kidney biopsy ranges between 5% and 37% in different renal biopsy registries. This wide variability is mainly dependent on the different definitions of CRF. In the period 1998-2006, the Triveneto Renal Biopsy Registry recorded 816 cases with CRF (defined as serum creatinine persistently > or =1.5 mg/dL), accounting for a prevalence of 27%. At the time of biopsy, the average age and glomerular filtration rate were 54 years and 41 mL/min, respectively; 70% of CRF patients are men and the prevalence of CRF increases with age. IgA nephropathy (IgAN) is the main histological form of glomerulonephritis, accounting for 23% of all cases of CRF. However, in subjects older than 65 years, membranous glomerulonephritis (MG) exceeds IgAN, thus becoming the main diagnosis in elderly patients with renal impairment. With a cutoff value for proteinuria of 3 g/day, the main diagnoses in cases with proteinuria below and above the cutoff are IgAN and MG, respectively. IgAN remains the main histological form of nephropathy throughout all levels of renal failure. These data confirm the findings of the Italian Registry of Renal Biopsies, but correspond only in part with data from other registries. The differences can to a certain extent be explained by the different criteria for the definition of renal impairment, patient selection, and differences in diagnosis among registries.

    Full Text Available Protein energy wasting is frequently observed in patients with advanced chronic renal failure and end-stage renal disease. Anorexia and reduced food intake are critical contributing factors and negatively impact on patients' survival. Ghrelin is a prophagic peptide produced by the stomach and acting at the hypothalamic level to increase the activity of orexigenic neurons. In patients with chronic renal disease, plasma levels are increased as a likely effect of reduced renal clearance. Nevertheless, patients' food intake is significantly reduced, suggesting inflammation-mediated resistance of hypothalamic nuclei to peripheral signals. A number of forms of evidence show that ghrelin resistance could be overcome by the administration of exogenous ghrelin. Therefore, ghrelin has been proposed as a potential strategy to improve food intake in chronic renal failure patients with protein energy wasting. Preliminary data are encouraging although larger prospective clinical trials are needed to confirm the results and to identify those patients who are likely to benefit most from the administration of exogenous ghrelin.

    Full Text Available Traditional herbal medicine is a global phenomenon especially in the resource poor economy where only the very rich can access orthodox care. These herbal products are associated with complications such as acute renal failure and liver damage with a high incidence of mortalities and morbidities. Acute renal failure from the use of herbal remedies is said to account for about 30–35% of all cases of acute renal failure in Africa. Most of the herbal medications are not usually identified, but some common preparation often used in Nigeria includes “holy water” green water leaves, bark of Mangifera indica (mango, shoot of Anacardium occidentale (cashew, Carica papaya (paw-paw leaves, lime water, Solanum erianthum (Potato tree, and Azadirachta indica (Neem trees. We report a rare case of a young man who developed acute renal failure two days after ingestion of Chinese herb for “body cleansing” and general wellbeing. He had 4 sessions of haemodialysis and recovered kidney function fully after 18 days of admission.

    Seven episodes of rhabdomyolysis with acute renal failure (ARF) have been observed in 6 patients treated with various short-acting tranquilizers and antidepressants. Clinical features usually included severe hyperthermia, diffuse hypertonicity with or without coma, circulatory failure or unstable blood pressure, and often acute respiratory failure. Serum CPK were always elevated. The type of ARF was prerenal failure without oliguria in 5/7 episodes, and acute tubular necrosis in 2/7 episodes, requiring hemodialyses in one patient. Three patients died. In any case, the tranquilizers and antidepressants responsible for this syndrome were stopped, and electrolyte disorders and acidosis were corrected. Associated acute circulatory failure, septicemia and/or acute hepatic failure required prompt therapy, and artificial ventilation was required in 4 instances. The further use of phenothiazines, butyrophenones, sulpiride and their derivatives should be avoided in any patient having developed such an accident, whose pathophysiology is similar to that described in malignant hyperthermia of various origin.

    Full Text Available Acute renal failure can cause neurologic manifestations such as mood swings, impaired concentration, tremor, stupor, coma, asterixis, dysarthria. Those findings can also be a sign of cerebral infarct. Here, we report a case of watershed cerebral infarction in a 70-year-old female patient with acute renal failure secondary to contrast administration and use of angiotensin converting enzyme inhibitor. Patient was evaluated with magnetic resonance imaging because of dysarthria. Magnetic resonance imaging revealed milimmetric acute ischemic lesion in the frontal and parietal deep white matter region of both cerebral hemisphere which clearly demonstrated watershed cerebral infarction affecting internal border zone. Her renal function returned to normal levels on fifth day of admission (BUN 32 mg/dl, creatinine 1.36 mg/dl and she was discharged. Dysarthria continued for 20 days.

    Staphylococcus Aureus is a Gram-positive cocci bacteria which had been found to be the causative organism in over 88% of patients with primary iliopsoas abscess. We report the case of a 53-year-old diabetic woman with end-stage renal failure diagnosed with left iliopsoas abscess with a catheter-related infection. Computed tomogram (CT) of abdomen and pelvis revealed hypodense lesions of left psoas, iliacus and quadratus lumborum suggestive of psoas abscesses. In addition, osteomyelitis changes at left sacroiliac and hip joint were seen. At surgery, she was found to have abscess at the posterior psoas muscle where she underwent open surgery drainage and percutaneous drain was inserted. A high index of suspicion of iliopsoas abscess should be maintained among haemodialysis patients presenting with intradialytic pelvic and hip pain and treated with optimal antibiotics therapy with appropriate surgical intervention.

    This article reviews our current understanding of the mechanisms of growth failure in chronic renal disease. The neuro-endocrine control of growth hormone secretion and insulin-like growth factor gene expression subject to use of corticosteroids, uremia, and metabolic acidosis are presented. It has been shown in other non-growth hormone deficient conditions such as Turner's syndrome that the use of exogenous growth hormone increases linear growth but also accelerates closure of the growth plate with no significant difference in the final height of such children. An understanding of growth factors is especially important and timely because of the tendency these days to use growth hormone to overcome the growth impairment of children with chronic renal failure.

    Introduction Acute Renal Failure (RF) is a rare but well recognized complication of Dengue Infection (DI). There has been paucity of published data regarding renal involvement in DI. Aim The aim of the present study was to elucidate different clinical presentations, disease outcomes of DI. To study the frequency, severity and predictors of RF in DI. Materials and Methods Patients diagnosed either as Dengue Fever (DF) or Dengue Haemorrhagic Fever/Dengue Shock Syndrome (DHF/DSS) respectively were enrolled for this study. The diagnostic criteria for DI were febrile illness associated with one of the following: 1) detection of dengue-specific IgM capture antibody or Non-Structural Protein1 (NS1) antigen; or 2) a four-fold or greater increase of dengue-specific IgG capture antibody by ELISA and haemoagglutination inhibition assay. Patients were diagnosed as having Acute RF, if serum creatinine was >1.2 mg/dl or who showed improvement by 50% in serum creatinine from the initial value. It is an observational study of medical charts, data of age, gender, and medical history of any underlying diseases in association with the severity of DI of each patient recorded. All of the laboratory results were collected. Parameters that influenced the clinical presentations and outcomes for development of classical DF or DHF/DSS in patients with or without RF were analysed and compared. Descriptive and inferential statistical analysis was carried. The Statistical software namely SAS 9.2, SPSS 15.0, Stata 10.1, Med Calc 9.0.1, Systat 12.0 and R environment ver.2.11.1 were used. Results Most common symptoms were fever followed by headache and pain in abdomen. Among the patients with RF, all patients had recovery. The patients with DHF/DSS were more susceptible to develop renal failure compared to DF group. There were statistically significant higher frequencies of renal failure, haemoconcentration, thrombocytopenia, low serum cholesterol. Patients in the RF group also had significantly

    We present a case of a non-Q wave myocardial infarction and acute renal failure following an ingestion of naphtha, a petroleum distillate composed primarily of hydrocarbons. The patient's renal, metabolic, and cardiac status improved over several days with aggressive volume replacement and bicarbonate therapy. Acute cardiotoxic effects of hydrocarbon exposure generally manifest as dysrhythmias, secondary to myocardial sensitization to circulating catecholamines, or, possibly, coronary vasospasm. Ischemia from associated hypotension or direct myocardial toxicity are other potential causes of naphtha-related cardiac injury.

    In chronic renal failure (CRF), renal impairment correlates with tubulointerstitial fibrosis characterized by inflammation, interstitial expansion with accumulation of extracellular matrix (ECM), tubular atrophy and vascular obliteration. Tubulointerstitial injury subsequent to glomerular sclerosis may be induced by proteinuria, leakage of glomerular filtrate or injury to the post-glomerular peritubular capillaries (hypoxia). In vivo data in animal models suggest that CRF is associated with hypoxia, with the decline in renal Po2 preceding ECM accumulation. Chronic renal failure is characterized by loss of microvascular profiles but, in the absence of microvascular obliteration, hypoxia can occur by a variety of complementary mechanisms, including anaemia, decreased capillary flow, increased vasoconstriction, increased metabolic demand and increased diffusion distances due to ECM deposition. Hypoxia regulates a wide array of genes, including many fibrogenic factors. Hypoxia-inducible factors (HIF) are the major, but not the sole, transcriptional regulators in the hypoxic response. In CRF, hypoxia may play a role in the sustained inflammatory response. In vitro studies in tubulointerstitial cells suggest that hypoxia can induce profibrogenic changes in proximal tubular epithelial cells and interstitial fibroblasts consistent with changes observed in CRF in vivo. The effect of hypoxia on renal microvascular cells warrants investigation. Hypoxia may play a role in the recruitment, retention and differentiation of circulating progenitor cells to the kidney contributing to the disease process and may also affect intrinsic stem cell populations. Chronic hypoxia in CRF fails to induce a sustained angiogenic response. Therapeutic manipulation of the hypoxic response may be of benefit in slowing progression of CRF. Potential therapies include correction of anaemia, inhibition of the renin-angiotensin system, administration of exogenous pro-angiogenic factors to protect the

    2009-01-01

    Full Text Available Acute renal failure (ARF is a common complication of sepsis and carries a high mortality. Renal replacement therapy (RRT during the acute stage is the mainstay of therapy. Va-rious modalities of RRT are available. Continuous RRT using convective methods are preferred in sepsis-induced ARF, especially in hemodynamically unstable patients, although clear evidence of benefit over intermittent hemodialysis is still not available. Peritoneal dialysis is clearly inferior, and is not recommended. Early initiation of RRT is probably advantageous, although the optimal timing of dialysis is yet unknown. Higher doses of RRT are more likely to be beneficial. Use of bio-compatible membranes and bicarbonate buffer in the dialysate are preferred. Anticoagulation during dialysis must be carefully adjusted and monitored.

    Atherosclerotic renal artery disease presents with a broad spectrum of clinical features, including heart failure as well as hypertension, and renal failure. Although recent randomized controlled trials failed to demonstrate renal artery stenting can reduce blood pressure or the number of cardiovascular or renal events more so than medical therapy, increasing attention has been paid to flash pulmonary edema and congestive heart failure associated with atherosclerotic renal artery disease. This clinical entity "renovascular heart failure" is diagnosed retrospectively. Given the increasing global burden of heart failure, this review highlights the background and catheter-based therapeutic aspects for renovascular heart failure.

    Full Text Available A insuficiência renal crônica é doença de elevada morbidade e mortalidade e sua incidência e prevalência em estágio terminal têm aumentado progressivamente a cada ano. Segundo a Sociedade Brasileira de Nefrologia, as principais causas de insuficiência renal crônica são hipertensão arterial, glomerulonefrite e diabetes mellitus. Diversos fatores elevam o risco de mortalidade em pacientes com nefropatia crônica, principalmente idade, presença de diabetes e número de comorbidades associadas. Para pacientes com menos de 50 anos de idade a taxa de sobrevida em 5 anos é de 62% e para aqueles acima desta idade e com diagnóstico de diabetes mellitus a sobrevida é de apenas 23%. A carambola, fruta originária da Ásia e muito difundida na maioria dos países tropicais, tem sido reportada como contendo uma neurotoxina capaz de provocar graves alterações neurológicas em pacientes com histórico de nefropatia crônica. Dentre estas alterações podemos observar desde quadros leves, como soluços e confusão mental, até quadros mais sérios, como convulsões e morte. Essa neurotoxina parece apresentar especificamente inibição sobre o sistema de condução GABAérgico. Descrevemos o caso de um paciente nefropata crônico que, após ingestão de carambola, inicia quadro de mal-estar, náuseas e vômitos, seguidos de episódios convulsivos reentrantes e vai a óbito mesmo com o tratamento hemodialítico convencional.Chronic renal failure is a high morbidity and mortality condition, with its terminal phase incidence and prevalence steadily growing year after year. According to the Sociedade Brasileira de Nefrologia [Brazilian Society of Nephrology], the main causes of renal failure are arterial hypertension, glomerulonephritis and diabetes mellitus.

    2005-01-01

    The intravascular administration of iodinated radiocontrast media can lead to acute renal dysfunction. Even small changes in renal function have been associated with increased morbidity and mortality, making the prevention of radiocontrast nephropathy of paramount importance. This review summarizes the principal risk factors for radiocontrast nephropathy and evidence-based preventive strategies that should be used to limit its occurrence. Risk factors for radiocontrast nephropathy include preexistent kidney disease, diabetes mellitus, dose of radiocontrast used, advanced congestive heart failure, and intravascular volume depletion. Proven preventive measures include volume expansion with intravenous saline or sodium bicarbonate and the use of low-osmolar or iso-osmolar radiocontrast media. Studies evaluating N-acetylcysteine have been conflicting, with meta-analyses suggesting a small beneficial effect. Studies of other pharmacologic agents have not demonstrated clinical benefit.

    1990-05-01

    This report encompasses data collected from all Canadian patients starting treatment for end-stage renal failure (ESRF) from 1981 until the end of 1987. Gross mortality showed an initial decline, but has stabilized since 1985. The year of entry into the system did not change the survival rate. There was an increase in the rate of acceptance of new patients between 1982 and 1987. The largest increases were in the older age groups, and resulted in a concomitant increase in the number of registered patients in older age groups. Survival on dialysis by age group declined with age. There was no difference in patient survival on hemodialysis or peritoneal dialysis. The probability of death for all patients entering the ESRF system remained constant notwithstanding year of entry into the system. It was slightly higher for males than females, much higher for patients with diabetes or renal vascular disease, higher with age, and much higher for patients not undergoing transplant.

    Leming, Melissa K; Breyer, Michael J

    2012-01-01

    Patients with renal failure who are taking trimethoprim have an increased risk of developing hyperkalemia, which can cause muscle weakness. In patients with postpolio syndrome, a normal creatinine level could be abnormally high, renal failure is possible because of lack of creatinine production, and the muscle weakness from resultant hyperkalemia could be more severe because of their underlying condition. This abnormally high creatinine level has been termed from this point relative renal failure. The objective of the study was to review a case in which relative renal failure and hyperkalemia caused muscle weakness that manifested as shortness of breath and confusion with electrocardiographic changes. A dehydrated patient with relative renal failure and postpolio syndrome had taken trimethoprim-sulfamethoxazole that caused symptomatic hyperkalemia. The patient presented with muscle weakness, shortness of breath, and confusion, with her postpolio syndrome compounding the situation and likely making the muscle weakness more severe. A patient on trimethoprim with renal failure is at an increased risk of developing hyperkalemia. Patients with postpolio syndrome could have severe muscle weakness from the hyperkalemia and could have renal failure even with a normal creatinine level. This case report will remind treating physicians to evaluate such patients for hyperkalemia if they present with muscle weakness, especially if the patient has renal failure and is on trimethoprim.

  1. Gastrointestinal function in chronic renal failure.

    Ravelli, A M

    1995-12-01

    Feeding problems, anorexia and vomiting are common in infants and children with chronic renal failure (CRF), and play a major role in the growth failure often found in this condition. However, the gastroenterological and nutritional aspects of CRF in children have received little attention, hence therapeutic interventions are usually empirical and often ineffective. Gastritis, duodenitis and peptic ulcer are often found in adults with CRF on regular haemodialysis and following renal transplantation. Despite persistent hypergastrinaemia, gastric acid secretion is decreased rather than increased in most of these patients, and active peptic disease appears to be promoted by the removal of the acid output inhibition (neutralisation of gastric acid by ammonia) that follows active treatment. Helicobacter pylori, on the other hand, does not seem to play a significant role in the pathogenesis of peptic disease in CRF. Gastro-oesophageal reflux has been found in about 70% of infants and children with CRF suffering from vomiting and feeding problems, and thus appears to be a major problem in these patients. In a number of symptomatic patients with CRF, gastric dysrhythmias and delayed gastric emptying have also been found; hence there appears to be a complex disorder of gastrointestinal motility in CRF. Serum levels of several polypeptide hormones involved in the modulation of gastrointestinal motility [e.g. gastrin, cholecystokinin (CCK), neurotensin] and the regulation of hunger and satiety (e.g. glucagon, CCK) are significantly raised as a consequence of renal insufficiency, and can be reverted to normal by renal transplantation. Furthermore, several other humoral abnormalities (e.g. hypercalcaemia, hypokalaemia, acidosis, etc.) are not uncommon in CRF. By directly affecting the smooth muscle of the gut or stimulating particular areas within the central nervous system, all these humoral alterations may well play a major role in the gastrointestinal dysmotility, anorexia

    2015-01-01

    Acute renal failure, now termed acute kidney injury(AKI), is frequently found in patients with cirrhosis. The occurrence of AKI, irrespective of the underlying cause, is associated with reduced in-hospital, 3-mo and 1-year survival. Hepatorenal syndrome is associated with the worst outcome among AKI patients with cirrhosis. Several definitions for AKI that have been proposed are outlined and evaluated in this paper. Among these, the International Club for Ascites-AKI criteria substantially strengthen the quality of early diagnosis and intervention according to underlying cause of AKI.

    2006-11-01

    Full Text Available Abstract Background Hornet stings are generally associated with local and occasionally anaphylactic reactions. Rarely systemic complications like acute renal failure can occur following multiple stings. Renal failure is usually due to development of acute tubular necrosis as a result of intravascular haemolysis, rhabdomyolysis or shock. Rarely it can be following development of acute tubulo-interstitial nephritis. Case presentation We describe a young male, who was stung on face, head, shoulders and upper limbs by multiple hornets (Vespa orientalis. He developed acute renal failure as a result of acute tubulo-interstitial nephritis and responded to steroids. Conclusion Rare causes of acute renal failure like tubulo-interstitial nephritis should be considered in a patient with persistent oliguria and azotemia following multiple hornet stings. Renal biopsy should be undertaken early, as institution of steroid therapy may help in recovery of renal function

    We present the case of a young adult patient with chronic renal failure who developed painful subcutaneous nodules after failed renal transplant and recommencing dialysis. These nodules were juxta-articular in location and initially located over both shoulders. Radiological evaluation suggested tumoral calcinosis. The patient was placed on a strict dialysis and dietary regimen but was suboptimally compliant with same. The patient developed progressive disease with an increase in size and number of juxta-articular calcified soft-tissue masses. However, 6 months following a second renal transplant clinical and radiological follow up demonstrated marked resolution both in symptomatology and radiographic findings. We present the plain radiographic, CT and MRI findings which demonstrate the typical radiological features of tumoral calcinosis. We correlate these findings with clinical course and histological findings following surgical excision of one of these masses.

    Full Text Available Adult coeliac disease commonly presents without classical symptoms as chronic diarrhea and weight loss. We describe the case of a 31-year-old woman with persistent life-threatening hypokalemia, acute renal failure, and acute quadriplegia due to diarrhea that had continued for one month. Although there are cases of coeliac disease diagnosed with hypokalemic rhabdomyolysis in the literature, none of the cases developed acute renal failure. This is the first case in the literature diagnosed with acute renal failure due to hypokalemic rhabdomyolysis as a presentation of coeliac disease. In acute renal failure cases that present with hypokalemic rhabdomyolysis due to severe diarrhea, coeliac disease should be considered as a differential diagnosis despite the negative antigliadin IgA antibody.

    2010-01-01

    Full Text Available Although hypercalcemia is a known metabolic complication of sarcoidosis, it is rarely a presenting manifestation. Long-standing hypercalcemia and hypercalciuria can cause nephrocalcinosis and chronic renal failure. Acute renal failure, although described, is also a rare presentation of patients with sarcoidosis. We describe two patients with sarcoidosis, who presented with severe hypercalcemia and worsening renal function. Parathyroid hormone levels were appropriately suppressed. This led to an extensive search for the cause of hypercalcemia. Finally, after a lymph node biopsy in both cases, a diagnosis of sarcoidosis was established, hypercalcemia resolved, and renal function improved in both cases after administration of prednisone.

    1975-01-01

    The term ‘functional renal failure’ has been used to describe the renal failure developing in advanced cirrhosis in which tubular function and structure remain intact. It may develop spontaneously, in which case prognosis is poor, but may be secondary to gastro-intestinal haemorrhage or excessive use of diuretics, in which case correction of the precipitating factor leads to improvement in renal function. It is suggested that the renal failure is due to a reduction in effective circulating plasma volume. PMID:1234327

    A retrospective study of 35 newborn with acute renal failure is presented. The main causes of renal failure were neonatal hypoxia by asfixia or hemorrhagic shock (eight), congenital malformations (two) and hypertonic dehydration (25). Mortality rate was 22% including two neonates with severe congenital malformations. Sepsis was considered as the main complicating factor and often as inducer of renal failure. It was present on 55% of cases and on 75% of the deceased newborn. Cerebral injury was frequent but a follow-up study is necessary to establish the rate of neurologic sequelae. Early diagnosis and treatment of renal failure will decrease complications with improvement in prognosis. Etiological analysis of neonatal renal failure shows the need of a better health education of people and also medical control of pregnancy and perinatal period.

    Acute decompensated heart failure is a common cause of hospitalisation. This is a period of vulnerability both in altered pathophysiology and also the potential for iatrogenesis due to therapeutic interventions. Renal dysfunction is often associated with heart failure and portends adverse outcomes. Identifying heart failure patients at risk of renal dysfunction is important in preventing progression to chronic kidney disease or worsening renal function, informing adjustment to medication management and potentially preventing adverse events. However, there is no working or consensus definition in international heart failure management guidelines for worsening renal function. In addition, there appears to be no concordance or adaptation of chronic kidney disease guidelines by heart failure guideline development groups for the monitoring of chronic kidney disease in heart failure. Our aim is to encourage the debate for an agreed definition given the prognostic impact of worsening renal function in heart failure. We present the case for the uptake of the Acute Kidney Injury Network criteria for acute kidney injury with some minor alterations. This has the potential to inform study design and meta-analysis thereby building the knowledgebase for guideline development. Definition consensus supports data element, clinical registry and electronic algorithm innovation as instruments for quality improvement and clinical research for better patient outcomes. In addition, we recommend all community managed heart failure patients have their baseline renal function classified and routinely monitored in accordance with established renal guidelines to help identify those at increased risk for worsening renal function or progression to chronic kidney disease.

    A 16 year old boy with Noonan syndrome diagnosed in the 3rd month of life was treated for renal insufficiency and hepatic tumor. Hemodialisis was started in preparation for surgery. Exacerbation of renal insufficiency occurred after surgical removal of the hepatic tumor together with the right hepatic lobe. Histopathologic examination showed adenoma hepatocellulare. Cysts in the extraperitoneal space appeared in the following months and were identified as cystes dysontogenetici benigni ``hamartia``. Renal function deteriorated during this time to end stage renal disease. The authors emphasize the possibility of good mental development in a patients with Noonan syndrome as well as the presence of urinary tract abnormalities and renal insufficiency of unknown origin - a phenomenon that has not yet been reported in other cases of Noonan syndrome.

    Renal specimens were obtained at surgery or postmortem from patients with autosomal dominant polycystic kidney disease (ADPKD). Patients had either serum creatinine (SCr) below 350 mumol/liter (N = 12) or terminal renal failure (N = 50). Specimens were examined by two independent observers using a carefully validated score system. Mean glomerular diameters were similar in ADPKD patients with early renal failure (176 +/- 38 microns) and in victims of traffic accidents (177 +/- 23 microns), while they were significantly greater in diabetics with comparable renal function (205 +/- 16 microns). Glomerular diameters in ADPKD patients with terminal renal failure (191 +/- 45 microns) and with early renal failure were not significantly different. On average, 29% of glomeruli (17 to 62) were globally sclerosed in early renal failure, and 49% (19 to 93) in terminal renal failure. The proportion of glomeruli with segmental sclerosis was less than 4% in both groups. Marked vascular sclerosis, interstitial fibrosis, and tubular atrophy were present in early renal failure, and even more so in terminal renal failure. Interstitial infiltrates were scarce and consisted mainly of CD4 positive lymphocytes and CD68 positive macrophages. Immunestaining with monoclonal renin antibodies showed an increased juxtaglomerular index and expression of renin by arterioles adjacent to cysts, as well as by cyst wall epithelia. The data show more severe vascular and interstitial, but not glomerular, changes in ADPKD with advanced as compared to early renal failure.

    Full Text Available Myxomas are rare tumors that can appear in many anatomical locations. There are only 14 cases of renal involvement documented in the literature. This article reports a case of renal myxoma in an elderly woman with recurrent cystitis. After five years of follow-up, the computed tomography (CT revealed a large solid tumor mass in the left kidney. Tumor resection was performed preserving the affected kidney with histopathological diagnosis of renal myxoma. The objective of this study is to report a rare case of renal myxoma, emphasizing the importance of the differential diagnosis from other benign and malignant mesenchymal tumors.

    Full Text Available Renal failure secondary to granulomatous sarcoidosis without clinical features or radiological evidence of disease is rare. In this case report, we describe a 14-year old girl who developed progressive renal failure over a two-month period which was associated with weight loss and epigastric pain. Physical examination did not show any abnormality. Laboratory investigations were normal except for normocytic normochromic anemia, high serum urea, high serum creatinine (452 tmol/L and polyclonal gammopathy. Percutaneous kidney biopsy showed severe interstitial nephritis with non-caseating granulomata. She was treated with tapered prednisone after a starting dose of 1 mg/kg. The treatment with prednisolone resulted in a complete remission that lasted up to two years of follow up. This case highlights the variable expression of sarcoidosis, which should be considered in the management of such disease.

    Full Text Available Paroxysmal nocturnal hemoglobinuria is a rare acquired disease, characterized by hemolytic anemia, recurrent infections, cytopenias, and vascular thrombosis. It occurs by non-malignant clonal expansion of one or more hematopoietic stem cells that acquired somatic mutations in PIG-A gene linked to chromosome X. This mutation results in lower erythrocyte expression of CD55 and CD59 surface proteins and consequently increased susceptibility to the complement system. The renal involvement is generally benign, resulting in mild impairment in urinary concentration. Acute renal failure requiring hemodialytic support accompanying PNH is rarely observed. The authors report a case of a 37-year-old male who presented with bicytopenia (hemolytic anemia and thrombocytopenia associated with acute renal failure requiring dialysis. Diagnosis was challenging because of the rarity and unfamiliarity with this entity, but was confirmed by flow cytometry. In the course of the disease, acute pyelonephritis with multiple renal abscesses was diagnosed requiring prolonged antibiotic therapy. Patient outcome was favorable after the control of hemolysis and the infection treatment.

    Renal amyloidosis is characterized by progressive deposition of extracellular material, most commonly in the glomeruli. Most often, patients present with nephrotic range proteinuria and the disease progresses gradually to renal failure. Rapid worsening of renal functions is rare. We report a case of crescentic glomerulonephritis superimposed on amyloidosis, clinically presenting as rapidly progressive renal failure, and present a review of the literature.

    1987-04-01

    In this study 17 patients, 11 with end-stage renal failure and six with nephrotic syndrome were selected. The selection criteria were presence of active intestinal schistosomiasis and absence of any surgical or other medical disease which could explain the renal disease. When examined by light microscopy, kidney biopsies showed membranoproliferative glomerulonephritis in nine, membranous in four, focal segmental glomerulosclerosis in two, sclerosing glomerulonephritis in one case, and no changes in another case. Direct immunofluorescence showed IgG deposits in 13 cases, IgM in 10 and different complement components (C3, C1q) in eight cases. Eluates from the kidney biopsies of the 17 schistosomal as well as six control cases were examined by ELISA against schistosoma mansoni adult worm antigen (AWA). This test showed the presence of antibodies against the AWA in 12 out of 17 of the schistosomal cases, and zero out of six of the controls. When examined by direct IFA using sheep anti-circulating anodic antigen/FITC and by indirect IFA using monoclonal antischistosomal CAA IgG3, kidney biopsies of the ELISA positive cases showed granular deposits of circulating anodic antigen (CAA). We conclude that schistosomal specific nephropathy does exist in the clinical settings and can lead to end-stage renal disease, with CAA probably being a major responsible antigen.

  18. A Medical Mystery: Unexplained Renal Failure in Burn Patients.

    Science.gov (United States)

    Lands, Harrison M; Drake, David B

    The objective of this study was to review the investigation that uncovered the medical mystery of burn patients developing unexpected renal failure. The authors examined published and unpublished manuscripts and case reports, as well as conducted personal interviews with primary sources. In the late 1970s, emergence of resistant bacterial strains to the topical antimicrobial silver sulfadiazine occurred at the University of Virginia Medical Center. In the search for an alternative topical antimicrobial with known coverage of Pseudomonas aeruginosa, Furacin Soluble Dressing was substituted. However, Furacin Soluble Dressing produced an unexpected toxicity syndrome of hyperosmolality, metabolic gap acidosis, hypercalcemia, and ultimately renal failure. In a search for an antimicrobial with an improved spectrum against Pseudomonas, a Federal Drug Administration-approved product was used to treat large surface area burns. An unexpected toxicity syndrome developed which was traced to the polyethylene glycol base of Furacin Soluble Dressing. This substance was absorbed through the burn wounds, metabolized, and resulted in a toxicity syndrome leading to renal failure. The burn community should be cautious when using products that may be approved as nontoxic for small surface area application, as they may have unexpected medical side effects when used with large surface area burns.

    Background Causes of “true” late kidney allograft failure remain unclear as study selection bias and limited follow-up risk incomplete representation of the spectrum. Methods We evaluated all unselected graft failures from 2008–2014 (n = 171; 0–36 years post-transplantation) by contemporary classification of indication biopsies “proximate” to failure, DSA assessment, clinical and biochemical data. Results The spectrum of graft failure changed markedly depending on the timing of allograft failure. Failures within the first year were most commonly attributed to technical failure, acute rejection (with T-cell mediated rejection [TCMR] dominating antibody-mediated rejection [ABMR]). Failures beyond a year were increasingly dominated by ABMR and ‘interstitial fibrosis with tubular atrophy’ without rejection, infection or recurrent disease (“IFTA”). Cases of IFTA associated with inflammation in non-scarred areas (compared with no inflammation or inflammation solely within scarred regions) were more commonly associated with episodes of prior rejection, late rejection and nonadherence, pointing to an alloimmune aetiology. Nonadherence and late rejection were common in ABMR and TCMR, particularly Acute Active ABMR. Acute Active ABMR and nonadherence were associated with younger age, faster functional decline, and less hyalinosis on biopsy. Chronic and Chronic Active ABMR were more commonly associated with Class II DSA. C1q-binding DSA, detected in 33% of ABMR episodes, were associated with shorter time to graft failure. Most non-biopsied patients were DSA-negative (16/21; 76.1%). Finally, twelve losses to recurrent disease were seen (16%). Conclusion This data from an unselected population identifies IFTA alongside ABMR as a very important cause of true late graft failure, with nonadherence-associated TCMR as a phenomenon in some patients. It highlights clinical and immunological characteristics of ABMR subgroups, and should inform clinical practice and

    Kerosene is a freely accessible hydrocarbon used in Sri Lankan (and other Asian) households for cooking and for lighting lamps. Kerosene poisoning is rarely reported among adults and its toxicological effects are not well known. Metformin is a commonly used oral hypoglycemic drug and its overdose leads primarily to lactic acidosis. Combined poisoning of metformin and kerosene and their interactions have not been reported. An 18-year-old, previously healthy, unmarried Sinhalese woman was referred following ingestion of 17.5 g of metformin and approximately 200 mL of kerosene oil in a suicide attempt. She had vomiting, burning epigastric pain, and a hypoglycemic seizure (capillary blood glucose of 42 mg/dL). Subsequently, she developed severe lactic acidosis followed by acute renal insufficiency, was treated with sodium bicarbonate, and underwent intermittent hemodialysis with bicarbonate. She recovered completely. This report proposes possible interactions that occur between metformin and kerosene that augment toxicity when the two are ingested together. It also stresses the importance of early treatment with intermittent hemodialysis in severe lactic acidosis with maintenance of blood glucose.

    Acute renal failure (ARF) is a serious medical complication during pregnancy, and, in the post-partum period, is associated with significant maternal morbidity and mortality as well as fetal loss. The objective of our study is to find the etiology and maternal outcome of ARF during pregnancy. The study was conducted at the Obstetrics and Gynecology Department of the Institute of Kidney Disease and Research Center, Ahmedabad, India from January 2009 to January 2011. Fifty previously healthy patients who developed ARF, diagnosed on oliguria and serum creatinine >2 mg%, were included in the study. Patients with a known history of renal disease, diabetes and hypertension were excluded from the study. All patients were followed-up for a period of six months. Patient re-cords, demographic data, urine output on admission and preceding history of antepartum hemorrhage (APH), post-partum hemorrhage (PPH), septicemia, operative interventions and retained product of conception were noted and need for dialysis was considered. Patients were thoroughly examined and baseline biochemical investigations and renal and obstetrical ultrasound were performed on each patient and bacterial culture sensitivity on blood, urine or vaginal swabs were performed in selected patients. The age range was 19-38 years (mean 26 ± 3.8). The first trimester, second trimester and puerperal groups comprised of four (8%), 25 (50%) and 21 patients (42%), respectively. Hemorrhage was the etiology for ARF in 15 (30%), APH in ten (20%) and PPH in five (10%) patients. Eleven (22%) patients had lower segment cesarian section (LSCS) while 36 (78%) patients had normal vaginal delivery. In 20 (40%) patients, puerperal sepsis was the etiological factor, while pre-eclampsia, eclampsia and HELLP syndrome accounted for 18 (36%) patients. Two (4%) patients had disseminated intravascular coagulation on presentation while one (2%) patient was diagnosed with hemolytic uremic syndrome. Maternal mortality was 12% (n = 6

    Full Text Available Acute nontraumatic exertional rhabdomyolysis may arise when the energy supply to muscle is insufficient to meet demands, particularly in physically untrained individuals. We report on a psychiatric patient who developed large bruises and hemorrhagic blisters on both hands and arms, rhabdomyolysis of both forearm muscles with a moderate compartment syndrome, and consecutive acute renal failure following excessive work in the garden. Although specifically asked, the patient denied any hard physical work or gardening, and heteroanamnestic data were not available. The diagnosis of rhabdomyolysis was easy to establish, but until reliable anamnestic data were obtained, the etiology remained uncertain. Four days after arrival, the patient recalled working hard in the garden. The etiology of rhabdomyolysis was finally reached, and the importance of anamnestic data was once more confirmed.

    Full Text Available "nAcute renal failure (ARF following cardiac surgery occurs in 1 to 10% of patients. Patients who develop ARF have higher rates of mortality. This study was undertaken to estimate the role of perioperative variables in predicting of post cardiac surgery ARF. We studied a cohort of 398 adult patients who underwent cardiac surgery at our institution from February 2004 to February 2006. Adult patients who were scheduled for cardiac valvular surgery, coronary artery bypass grafting (CABG or both, with or without cardiopulmonary bypass (CPB were included. Exclusion criteria were death within two days of operation (n= 8, incomplete patient data, and preexisting renal dysfunction and dialysis requirement or a baseline serum creatinine > 4 mg/dl. Age, sex, left ventricular ejection fraction, diabetes, preoperative, presence of proteinuria (on dipstick, type of surgery, use of CPB and duration of surgery were recorded. A logistic regression analysis was performed to assess independent contribution of variables in the risk of ARF. A binary logistic regression revealed age was an independent predictor of ARF (P < 0.05. When both all variables were included in a multinominal logistic regression model, preoperative proteinuria independently predicted ARF (Odds ratio= 3.91, 95% CI: 1.55-9.91, P = 0.004. Our results revealed that special considerations should be given to elderly and patients with proteinuria when managing post cardiac surgery ARF.

    Full Text Available HBV infection in chronic renal failure (CRF becomes chronic in 30 to 60% compared with less than 10% in nonuremic patients. Immunological dysfunction in patients on hemodialysis may be related to imbalanced cytokine systems, such as tumor necrosis factor (TNF-|α| and interleukin (IL 6,1 by retention of renal metabolite in uremia and chronic inflammation and have a poor immunological reaction to T-cell-dependent antigens, like hepatitis B vaccination. Immunocompromised patients who are unresponsive to hepatitis B vaccination seem to be unable to enhance IL-10 synthesis for control of monokine overproduction. Moreover, human leukocyte antigen (HLA genes, which play a major role in the antigen presentation to immunocompetent cells, have also been shown to modulate this immune response. Unfortunately, seroconversion to anti-HBS has been reported to occur in only 40 to 50% of the vaccine, a significantly lower rate than that observed in healthy adults. Various methods including adjutants such as zinc, gamma interferon, thymopentine, GM-CSF and Levamisol for improving immune responses have been advised. Experience with Pres1/s2, third-generation vaccines is limited and they have not been proven more effective than intradermally (ID administered second-generation S antigen vaccines. Both intramuscular (IM and intradermal (ID vaccinations against hepatitis B have variable efficiency in hemodialysis and non-responders should be retreated by ID route.

    2017-01-01

    The activation of the sympathetic nervous system is associated with cardiovascular hospitalizations and death in heart failure. Renal denervation has been shown to effectively reduce sympathetic overdrive in certain patients with uncontrolled hypertension. Pilot trials investigating renal denervation as a potential treatment approach for heart failure were initiated. Heart failure comorbidities like obstructive sleep apnea, metabolic syndrome and arrhythmias could also be targets for renal denervation, because these occurrences are also mediated by the activation of the sympathetic nervous system. Therefore, renal denervation in heart failure is worthy of further investigation, although its effectiveness still has to be proven. Herein, we describe the pathophysiological rationale and the effect of renal denervation on surrogates of the heart failure syndrome.

    Euphorbia paralias is known in traditional medicine as an anti-inflammatory agent, a purgative and for its local anesthetic property. To the best our knowledge, renal toxicity of this substance has not been previously reported. In this paper, we report the case of a 29-year-old male who developed renal damage following ingestion of Euphorbia paralias. He had been on follow-up for nephrotic syndrome since 1986, although irregularly, with several relapses but each responding well to steroid therapy. A kidney biopsy had not been performed earlier due to refusal by the patient. He was off steroids since April 2008 because the patient developed osteoporosis. He was admitted with general malaise and oliguria to our department in May 2009, following repeated vomiting and watery diarrhea for three days. On examination, he was edematous but had normal vital signs except for a pulse rate of 120/min. Hemoglobin was only 5.5 g/dL but with normal white cell and platelet counts. Blood biochemistry showed evidence of advanced renal failure with a serum creatinine level of 1835 μmol/L and urea at 44.6 mmol/L, sodium of 132 μmol/L and potassium at 4.3 mmol/L. He had features of nephrotic syndrome with severe hypoproteinamia and 24-h urinary protein of 10.45 g. Ultrasonography revealed enlarged kidneys with a reduced echogenecity of the medulla and the papillae. Subsequently, after hemodialysis with blood transfusion, a kidney biopsy was performed that showed focal segmental glomerulosclerosis associated with an acute tubular injury. On intensive interrogation, the patient gave a history of ingesting boiled Euphorbia paralias as a native treatment for edema, ten days prior to the onset of the current illness. A diagnosis of acute renal failure (ARF) resulting from the possible nephrotoxic effect of Euphorbia paralias poisoning was made. He was treated with intermittent hemodialysis and corticosteroids.

    Hashimoto's thyroiditis is the commonest form of autoimmune thyroiditis in the world. It occurs most frequently in women (female/male ratio, 6:1) in the age group between 30 and 60 years. Here we report the case of a 38-year-old Caucasian man who presented with a few days' history of upper limb paresthesias, widespread joint and muscle pain, and headaches. Laboratory findings showed increased CPK, myoglobin and plasma creatinine levels with acute renal failure. Low free T3 and T4 values associated with a high TSH value, the presence of antithyroid globulin and peroxidase autoantibodies pointed to a diagnosis of hypothyroidism with Hashimoto's thyroiditis. Treatment with levothyroxine was initiated and within 2 months normalization of renal function, myoglobin, CPK and thyroid hormone levels was observed.

The disease is divided into two groups: the primary group and the secondary group. The classical or primary perforating dermatoses are subdivided into four types according to the eliminated dermal materials: Kyrle disease, perforating reactive collagenosis, elastosis perforans serpiginosa, and perforating folliculitis. The secondary form is known as acquired perforating dermatosis. The term was proposed in 1989 by Rapini to designate the perforating dermatoses affecting adult patients with systemic disease, regardless of the dermal materials eliminated. This report describes a case of the disease with elimination of collagen and elastic fibers in a patient with chronic renal failure.

    Hepatitis A infection may result in acute hepatitis, and rarely, fulminant hepatitis may ensue. Extrahepatic manifestations of hepatitis A are uncommon. The authors present the case of a 77-year-old male who had development of acute renal failure and pericarditis during the clinical course of acute hepatitis A infection. He died as a result of septic shock on the fifth day of hospitalization. To the best of our knowledge, this is the first report of both these rare and serious complications appearing in the same patient.

    Full Text Available Abstract Background Dialysis disequilibrium syndrome (DDS is the clinical phenomenon of acute neurologic symptoms attributed to cerebral edema that occurs during or following intermittent hemodialysis (HD. We describe a case of DDS-induced cerebral edema that resulted in irreversible brain injury and death following acute HD and review the relevant literature of the association of DDS and HD. Case Presentation A 22-year-old male with obstructive uropathy presented to hospital with severe sepsis syndrome secondary to pneumonia. Laboratory investigations included a pH of 6.95, PaCO2 10 mmHg, HCO3 2 mmol/L, serum sodium 132 mmol/L, serum osmolality 330 mosmol/kg, and urea 130 mg/dL (46.7 mmol/L. Diagnostic imaging demonstrated multifocal pneumonia, bilateral hydronephrosis and bladder wall thickening. During HD the patient became progressively obtunded. Repeat laboratory investigations showed pH 7.36, HCO3 19 mmol/L, potassium 1.8 mmol/L, and urea 38.4 mg/dL (13.7 mmol/L (urea-reduction-ratio 71%. Following HD, spontaneous movements were absent with no pupillary or brainstem reflexes. Head CT-scan showed diffuse cerebral edema with effacement of basal cisterns and generalized loss of gray-white differentiation. Brain death was declared. Conclusions Death is a rare consequence of DDS in adults following HD. Several features may have predisposed this patient to DDS including: central nervous system adaptations from chronic kidney disease with efficient serum urea removal and correction of serum hyperosmolality; severe cerebral intracellular acidosis; relative hypercapnea; and post-HD hemodynamic instability with compounded cerebral ischemia.

    A uremic patient on hemodialysis, who had concurrent cardiomyopathy showed intense myocardial uptake of {sup 99m}Tc-methylene diphosphonate (MDP). The presumed cause of uptake in the myocardium is metastatic calcification due to hypercalcemia secondary to the renal failure. However, supplementary mechanism caused by cardiomyopathy should be considered. We describe a case with bone tracer uptake in the myocardium in the absence of infarction in a patient with chronic renal failure.

    Background Acute renal failure describes as a syndrome by rapid decline in the ability of the kidney to eliminate waste products, regulate acid–base balance, and manage water homeostasis. When this impairment is prolonged and entered chronic phase, erythropoietin secretion by this organ is decreasing and toxic metabolic accumulates and causes hematological changes include decrease of HCT, MCV and RBC and platelet counts. This study evaluates present of anemia and thrombocytopenia in patients with acute and chronic renal failure. Materials and Methods This study conducted on 132 patients with renal impairment and also 179 healthy individuals as two separated control groups. Initially patients with renal problem were tested and after confirmation of impairment, patients were divided in two groups, acute with less than 3 months and chronic with more than 3 months renal failure, based on duration of the disease. Then complete blood count performed for each patient and finally obtained data were analyzed by SPSS software. Results Comparison between 96 patients with acute and 36 patients with chronic renal failure revealed that severity of anemia (HCT, Hb and MCV) between these two groups were statistically high in comparison with control groups (P > 0.05) but thrombocytopenia in patients with chronic renal failure was statistically different from control and the acute ones (P < 0.001). Conclusion It was recommended that in patients with chronic renal failure, to prevent the risk of bleeding, platelet count should be checked periodically. PMID:24505541

    Full Text Available Systemic lupus erythematosus (SLE is a chronic, occasionally life-threatening, multisystem disorder, and renal involvement is one of the most common and most serious complications of SLE. Among the various histological types of lupus nephritis, diffuse proliferative nephritis carries the worst prognosis. A 28-year-old woman was admitted to Baskent University Adana Hospital with the complaints of dyspnea, chest pain, and fatigue. The patient had active lupus manifestations including generalized pleural and pericardial effusion, hypoalbuminemia, anemia, leucopenia, hypocomplementemia, markedly elevated ANA, acute kidney injury, and uncontrolled hypertension. Renal biopsy had been performed at another institute and shown type 4 lupus nephritis. She had been managed with methylprednisolone and cyclophosphamide (CYP for 6 months. We started immunosuppressive therapy with intravenous methylprednisolone (1 gr/day for 3 days as an induction therapy. The treatment was continued with oral methylprednisolone 0.5 mg/kg/day and mycophenolate mofetil (MMF 1 gr/day. Hemodialysis (HD therapy was initiated because of progressive renal failure and hypervolemia during the clinical course. Despite the improvement in her general condition, the patient underwent HD treatment three times a week for 5 months. On the fifth month of MMF therapy the renal function and diuresis were progressively improved and HD treatment was terminated. Management with MMF may be effective for remission of lupus nephritis in patients who are nonresponders to initial CYC therapy.

    Can science discover some secrets of Greek mythology? In the case of Prometheus, we can now suppose that his amazing hepatic regeneration was caused by a peptide growth factor called hepatocyte growth factor (HGF). Increasing evidence indicates that HGF acts as a multifunctional cytokine on different cell types. This review addresses the molecular mechanisms that are responsible for the pleiotropic effects of HGF. HGF binds with high affinity to its specific tyrosine kinase receptor c-met, thereby stimulating not only cell proliferation and differentiation, but also cell migration and tumorigenesis. The three fundamental principles of medicine-prevention, diagnosis, and therapy-may be benefited by the rational use of HGF. In renal tubular cells, HGF induces mitogenic and morphogenetic responses. In animal models of toxic or ischemic acute renal failure, HGF acts in a renotropic and nephroprotective manner. HGF expression is rapidly up-regulated in the remnant kidney of nephrectomized rats, inducing compensatory growth. In a mouse model of chronic renal disease, HGF inhibits the progression of tubulointerstitial fibrosis and kidney dysfunction. Increased HGF mRNA transcripts were detected in mesenchymal and tubular epithelial cells of rejecting kidney. In transplanted patients, elevated HGF levels may indicate renal rejection. When HGF is considered as a therapeutic agent in human medicine, for example, to stimulate kidney regeneration after acute injury, strategies need to be developed to stimulate cell regeneration and differentiation without an induction of tumorigenesis.

  3. Nephrotic Syndrome and Acute Renal Failure Apparently Induced by Sunitinib

    Full Text Available We report a case of nephrotic syndrome and acute renal failure apparently induced by sunitinib. A 67-year-old man with a history of metastatic renal cell carcinoma presented with progressive kidney dysfunction with proteinuria, general edema, and body weight gain of 21 kg after undergoing 3 weeks of sunitinib therapy. The patient had taken no other over-the-counter medications, and all other possible causes of nephrotic syndrome were excluded. The Naranjo Adverse Drug Reaction Probability Scale score for this event was 6, indicating a high probability that the observed presentations were associated with use of the drug. However, despite the discontinuation of sunitinib, his condition deteriorated, and hemodialysis was initiated for respiratory distress. A renal biopsy was performed, which revealed ischemic acute tubular necrosis with minimal change nephropathy. In conclusion, nephrologists and oncologists should be aware that nephrotic syndrome with ischemic acute tubular necrosis is a possible adverse effect of sunitinib. For early diagnosis of this condition and to avoid renal damage, we recommend differential diagnosis of serum creatinine and proteinuria in patients undergoing sunitinib therapy.

    Manifestations of breast abnormalities in these patients included breast calcifications, duct dilatation, fibrocystic change, rapidly enlarged multiple fibroadenomas, edema, invasive ductal cancer, extensive fibrosis, spontaneous hemorrhage, and Mondor's disease. These interesting cases we experienced are reported. Prolactin, growth hormone, and cortisol are required concurrently for normal development of mammary epithelium. Hormonal profile of chronic renal failure is different to normal person due to decreased renal clearance. The incidence of breast cancer is also increased in CRF. Metastatic soft tissue calcification is well described finding in chronic renal failure related to an increase in serum calcium phosphate product and secondary hyperparathyroidism. Kidney failure alone may increases prolactin level. The possibility of deranged hypothalamic-pituitary control mechanisms do not excluded. Impaired prolactin response to TRH stimulation has also been observed. Methyldopa and tricyclic antidepressants specifically were associated with hyperprolactinemia. Cyclosporin administration may elevate serum prolactin levels with simultaneous down regulation of prolactin receptors. Some populations of lymphocytes and fibroblasts exhibit cyclosporin receptors. Cyclosporin could potentially promote fibroadenomas by direct action, and seems to alter LH secretion.

    Perirenal fluid accumulation has been described as an ultrasonographic feature of urine leakage, hemorrhage, abscessation, or neoplasia. The purpose of this retrospective study was to report perirenal effusion as an additional ultrasonographic finding in canine and feline patients with acute renal failure. The causes of acute renal failure in 18 patients included nephrotoxicity (4), leptospirosis (3), ureteral obstruction (2), renal lymphoma (2), ureteronephrolithiasis (2), prostatic urethral obstruction (1) and interstitial nephritis and ureteritis (1). An underlying cause was not identified in three patients. The sonographic finding of perirenal fluid was bilateral in 15 patients. Unilateral perirenal fluid was identified ipsilateral to the site of ureteric obstruction in two patients. Large effusions extended into the caudal retroperitoneal space. Additional sonographic findings suggestive of renal parenchymal disease included mild (5), moderate (5) or severe (2) pyelectasia, increased renal echogenicity (11), increased (9) or decreased renal size (2) and ureteral and/or renal calculi (3). There did not appear to be an association between the volume of perirenal fluid and the severity of renal dysfunction. All patients with large effusions underwent euthanasia. Perirenal fluid developing in acute renal failure is thought to be an ultrafiltrate associated with tubular back-leak into the renal interstitium that overwhelms lymphatic drainage within the perirenal and retroperitoneal connective tissues although obstruction to urine flow may also play a role. Localized perirenal retroperitoneal free fluid may be a useful ultrasonographic feature to assist with the characterization of, and determination of prognosis in, patients with suspected renal disease.

    Full Text Available Rhabdomyolysis is caused by muscle breakdown resulting in the release of myoglobin into the systemic circulation. Acute renal failure results from the nephrotoxicity of myoglobin. Heroin use is one of the causes of rhabdomyolysis and acute renal failure. Aim: The aim of this literature review was highlight the importance of early recognition and treatment by a nurse of acute renal failure from rhabdomyolysis after heroin. Method: The method followed in this review was based on retrospective studies and research, conducted during the period 2000-2012 and retracted from the international databases Medline, Pubmed, Cinahl and the Greek database Iatrotek on acute renal failure from rhabdomyolysis after heroin use. Key-words were used: acute renal failure, rhabdomyolysis, heroin, international guidelines, based-evidence nursing care. Results: The clinical presentation occurs with muscle pain, muscle weakness, and brown-redish urine. High values of CPK and myoglobin make the diagnosis. Toxicology tests confirm heroin use. For the treatment is required naloxone administration, the rapid hydration of the patient, alkalinization of urine, good diuresis, regulation of electrolyte disturbances and dialysis if necessary. Conclusions: Early recognition and treatment of acute renal failure from rhabdomyolysis after heroin use is vital for the survival of the patient. It is necessary to educate nurses on specific issues such as acute renal failure from rhabdomyolysis after heroin use and the implementation of protocols for the treatment and cure.

  7. Mechanisms of renal cell repair and regeneration after acute renal failure.

    In many cases, acute renal failure (ARF) is the result of proximal tubular cell injury and death and can arise in a variety of clinical situations, especially following renal ischemia and drug or toxicant exposure. Although much research has focused on the cellular events leading to ARF, less emphasis has been placed on the mechanisms of renal cell repair and regeneration, although ARF is reversed in over half of those who acquire it. Studies using in vivo and in vitro models have demonstrated the importance of proliferation, migration, and repair of physiological functions of injured renal proximal tubular cells (RPTC) in the reversal of ARF. Growth factors have been shown to produce migration and proliferation of injured RPTC, although the specific mechanisms through which growth factors promote renal regeneration in vivo are unclear. Recently, interactions between integrins and extracellular matrix proteins such as collagen IV were shown to promote the repair of physiological functions in injured RPTC. Specifically, collagen IV synthesis and deposition following cellular injury restored integrin polarity and promoted repair of mitochondrial function and active Na(+) transport. Furthermore, exogenous collagen IV, but not collagen I, fibronectin, or laminin, promoted the repair of physiological functions without stimulating proliferation. These findings suggest the importance of establishing and/or maintaining collagen IV-integrin interactions in the stimulation of repair of physiological functions following sublethal cellular injury. Furthermore, the pathway that stimulates repair is distinct from that of proliferation and migration and may be a viable target for pharmacological intervention.

    Renal transplantation is the best therapeutic option for end-stage chronic renal disease. Assuming that it is more advisable if performed early, we aimed to show the clinical, social, and economic advantages in 70% of our patients who were dialyzed only for a short period. For this purpose, we retrospectively collected data over 28 years in 142 kidney transplants performed in patients with transplantation, 64% of our patients had no public support; however, 64% of them returned to work and got health insurance 2 months later. Full rehabilitation was achieved in all cases, including integration to the family, return to full-time work, school and university, sports, and reproduction. Immunosuppression consisted of 3 drugs, including steroids, cyclosporine, and azathioprine or mycophenolate. The cost in the 1st year, including patient and donor evaluation, surgery, immunosuppression, and follow-up, was $13,300 USD versus $22,320 for hemodialysis. We conclude that preemptive renal transplantation with renal failure, especially in developing countries such as Bolivia, where until last year, full public support for renal replacement therapy was unavailable.

    The authors observed two cases with crossed renal dystopia, to which venous urography, renal scintigraphy, echographic and gamma-chamber investigations were performed. The venous urography, in case of the appropriate symptomatics, is stressed to be able to establish the presence of heterolateral dystopia by as far as the distributional function of the anomaly is concerned--the gamma-chamber investigation is with the highest information value.

    Renal failure is a frequent complication of multiple myeloma (MM). Recently, the combination of lenalidomide-dexamethasone has become one of the cornerstone regimens for the treatment of MM. Impairment of renal function exacerbation is a rare, but potential, complication of lenalidomide therapy in plasma cell dyscrasias. We present two patients who developed exacerbation of renal function during their first cycle of therapy with lenalidomide. In the first case, we present a 76-year-old-male with MM and impaired renal function, who declined two weeks after initiation of second-line therapy with lenalidomide. His renal functions improved after discontinuation of lenalidomide and with supportive care. In the second case, we describe a 61-year-old woman who was started on lenalidomide for relapsed MM and admitted to intensive care unit three weeks later due to severe renal failure. Despite intensive supportive care, her renal function deteriorated even more and she died. We conclude that renal failure is an uncommon, but serious, potential complication of lenalidomide therapy in plasma cell dyscrasias, particularly MM. Close monitoring of renal function is clearly recommended during this treatment.

    Full Text Available BACKGROUND: We have noticed a recent rise in the incidence and severity of acute renal failure (ARF in malaria. AIM: To study the incidence, severity and outcome of ARF in malaria. SETTING and DESIGN: It is a retrospective analysis of data of one year from a tertiary medical centre in a metropolitan city. MATERIALS AND METHODS: Patients with ARF and smear positive malaria were evaluated. STATISTICAL ANALYSIS: Results were expressed as mean, range and standard deviation. RESULTS: Out of 402 detected smear positive malaria, 24 had ARF. Eighteen were of the age group 21-40 years. Plasmodium falciparum (PF was detected in 16, Plasmodium vivax in three, and mixed infection in five. Non-oliguric ARF was seen in 14. Eighteen showed severe ARF (Serum creatinine >5 mg%. Twenty-two patients needed dialysis. Prolonged ARF lasting for 2-6 weeks was seen in eight. Seventeen patients recovered completely, while seven showed fatal combination of disseminated intravascular coagulation (DIC, acute respiratory distress syndrome (ARDS, severe ARF and PF malaria. No response was seen to chloroquine and artesunate given alone and twenty patients required quinine. CONCLUSION: ARF necessitating dialysis was seen in 92% of patients with ARF in malaria. PF infection, severe ARF, DIC and ARDS were poor prognostic factors. Resistance was noted to both chloroquine and artesunate.

    2001-01-01

    The aim of this work was to review evidence on the role of the sympathetic nervous system (SNS) in chronic renal failure (CRF). Three main points are discussed: 1) SNS and pathogenesis of arterial hypertension; 2) SNS and cardiovascular risk; 3) implication of SNS in arterial hypotension during hemodialysis. Several lines of evidence indicate the presence of a sympathetic hyperactivity in CRF, and its relationship with arterial hypertension. It is suggested that diseased kidneys send afferent nervous signals to central integrative sympathetic nuclei, thus contributing to the development and maintenance of arterial hypertension. The elimination of these impulses with nephrectomy could explain the concomitant reduction of blood pressure. Several experiments confirmed this hypothesis. Regarding SNS and cardiovascular risk, some data suggest that reduced heart rate variability identifies an increased risk for both all causes and sudden death, independently from other recognized risk factors. Symptomatic hypotension is a common problem during hemodialysis treatment, occurring in approximately 20-30% of all hemodialysis sessions and is accompanied by acute withdrawal of sympathetic activity, vasodilation and relative bradicardia. This reflex is thought to be evoked by vigorous contraction of a progressively empty left ventricle, activating cardiac mechanoceptors. This inhibits cardiovascular centers through vagal afferents, and overrides the stimulation by baroreceptor deactivation. Alternative explanations include cerebral ischemia and increased production of nitric oxide, which inhibit central sympathetic activity. It is hoped that therapies aimed at modulating sympathetic nerve activity in patients with CRF will ameliorate their prognosis and quality of life.

    A 63-year old male was referred to our emergency unit due to acute renal failure. The level of serum renal function tests levels, blood urea nitrogen (BUN)/creatinine, were 63 mmol/L/848 μmol/L. CT (Computarised Tomography) scan showed a huge bladder stone (5 cm x 6 cm x 5 cm) with increased bladder wall thickness. Post-renal acute renal failure due to bilateral ureterohydronephrosis was diagnosed. The huge bladder stone was considered to be the cause of ureterohydronephrosis and renal failure. The patient was catheterised and received haemodialysis immediately. He received haemodialysis four times during ten days of hospitalization and the level of serum renal function tests levels (BUN/ creatinine) decreased 18 mmol/L/123 μmol/L. After improvement of renal function, we performed cystoscopy that demonstrated normal prostatic urethra and bladder neck and bilaterally normal ureteral orifices. Bladder wall was roughly trabeculated and Bladder outlet was completely obstructed by a huge bladder stone. After cystoscopy open, cystolithotomy was performed to remove calcium phosphate and magnesium ammonium phosphate stone weighing 200 g removed. Four days after operation the patient was discharged uneventfully and urethral catheter was removed on the seventh day. Post-renal acute renal failure due to large bladder stones is rare in literature. According to the our knowledge; early diagnosis of the stone avoid growth to large size and prevent renal failure.

    Full Text Available Venomous snakebite is a common problem in India. The aim of this study is to assess the prevalence, risk factors and prognostic factors in snakebite induced acute renal failure and to determine their outcome from a tertiary care center in India. A total of 1548 cases of snakebite admitted to adult medical wards of Government Rajaji hospital from January 2003 to December 2004, were studied from hospitalization to discharge or death. There were 1180 poisonous and 368 nonpoisonous snakebites. Among the poisonous, there were 1121 viperidae and 59 elapidae bites. A total of 159 (13.5% patients (M = 98, F = 61 developed acute renal failure; of them 72 (45.3% required dialysis and 36 (22.6% expired (of them, 23 required dialysis. ARF patients were older than non ARF (39.1 vs. 35.4 years, p = 0.03. Cellulites (OR 9.20, p = 0.032, regional lymphadenopathy (OR 22.0, p= 0.001, intravascular hemolysis (OR 3.70, p = 0.004 and bite to needle time more than 2 hours (OR 2.10, p = 0.001 were identified as independent risk factors for the development of acute renal failure. Bite to needle time more than 2 hours (OR 2.10, p = 0.01, presence of intravascular hemolysis (OR 13.0, p = 0.004 and hypotension (OR 22.2, p = 0.04 and the presence of bleeding manifestations (OR 7.91, p = 0.032 were identified as independent predictors of poor outcome in snakebite victims. We conclude that our study demonstrates several risk factors and predictors for the development and outcome of ARF in patients with snakebites.

    Renal transplantation is often associated with severe complications. Except for acute rejection, infections and toxicity of immunosuppressive treatment are the most frequent problems observed after transplantation. Infections with hepatic viruses (HBV, HDV, HCV, HGV) and cytomegalic virus (CMV) are the main infectious complications after renal transplantation. Cyclosporine toxicity is not unusual for a patient with renal transplantation and is even more frequent for patients with hepatic impairment due to viral infections. The subjects of this report are two renal transplant recipients with acute pancreatitis, severe hepatitis and acute renal failure on graft, receiving immunosuppressive therapy for maintaining renal graft function

    The association between cardiac failure and renal function impairment has gained wide recognition over the last decade. Both structural damage in the form of systemic atherosclerosis and (patho) physiological hemodynamic changes may explain this association. As regards hemodynamic factors, renal impairment in chronic heart failure is traditionally assumed to be mainly due to a decrease in cardiac output and a subsequent decrease in renal perfusion. This will lead to a decrease in glomerular filtration rate and a compensatory increase in tubular sodium retention. The latter is a physiological renal response aimed at retaining fluids in order to increase cardiac filling pressure and thus renal perfusion. In heart failure, however, larger increases in cardiac filling pressure are needed to restore renal perfusion and thus more volume retention. In this concept, in chronic heart failure, an equilibrium exists where a certain degree of congestion is the price to be paid to maintain adequate renal perfusion and function. Recently, this hypothesis was challenged by new studies, wherein it was found that the association between right-sided cardiac filling pressures and renal function is bimodal, with worse renal function at the highest filling pressures, reflecting a severely congested state. Renal hemodynamic studies suggest that congestion negatively affects renal function in particular in patients in whom renal perfusion is also compromised. Thus, an interplay between cardiac forward failure and backward failure is involved in the renal function impairment in the congestive state, presumably along with other factors. Only few data are available on the impact of intervention in volume status on the cardio-renal interaction. Sparse data in cardiac patients as well as evidence from cohorts with primary renal disease suggest that specific targeting of volume overload may be beneficial for long-term outcome, in spite of a certain further decrease in renal function, at least

    In patients with renal or hepatic failure, the pharmacokinetics of opioids may be affected in several ways, leading to the necessity to correct the dose. The liver is the major site for biotransformation of most opioids. The major metabolic pathway is oxidation. Exceptions to this are morphine and buprenorphine, which undergo primarily glucuronidation, and remifentanil which is cleared by esther hydrolysis. The hydrophilic metabolites are predominantly excreted by the kidneys and may accumulate in patients with renal insufficiency. Some metabolites such as morphine-6-glucuronide (M6G) or normeperidine are active opioid agonists. With high concentrations they may cause narcotic effects or respiratory depression. In addition, special risks are known for normepridine that has been shown to exert neurotoxic effects with the risk of seizures. Few cases of respiratory depression following the administration of codeine, dihydrocodeine and tramdol have been reported. The elimination half-life of these drugs was prolonged. Lastly, the disposition of methadone, buprenorphine, fentanyl, sufentanyl and remifentanil appears to be unaffected in renal failure. In patients with hepatic cirrhosis it has been shown that oxidation of opioids is reduced, resulting in a decreased drug clearance (meperidine, propoxyphene, pentazocine, tramadol and alfentanil) and increased oral bioavailability due to reduced first-pass metabolism (meperidine, propoxyphene, pentazocine, dihydrocodeine). Although glucuronidation is thought to be less affected in liver cirrhosis, the clearance of morphine was found to be decreased and its oral bioavailability increased. The consequence of reduced drug metabolism is the risk of accumulation in the body, especially with repeated administrations. As for patients with renal failure, special risks are known for meperidine with potential accumulation of normeperidine, which can cause seizures, and for propoxyphene for which several cases of hepatotoxicity have

    Sepsis is a clinical syndrome related to severe infection and is characterized by systemic inflammation and injury to multiple organs and functional systems. Sepsis is one of the main causes of acute renal failure (ARF). Diuretics are frequently administered during ARF. However, there is scant evidence that diuretics provide any benefit to the patients with ARF. This case report highlights the occurrence of uremia and nonrecovery of renal function after administration of diuretics in a patient with ARF caused by sepsis. It is suggested that physicians should be cautious in prescribing diuretics to patients with ARF due to septicemia. Diuretics cause uremia and may lead to false diagnosis of chronic renal failure and nonrecovery of renal function. The patient may unnecessarily require prolonged dialysis. PMID:22022011

    The human erythrocyte (RBC) is a target organ for parathyroid hormone (PTH) and the hormone increases RBC osmotic fragility and induces their hemolysis. The present study was undertaken to examine whether elevated blood levels of PTH affect RBC survival, and therefore whether PTH, being an extracorpuscular factor, is responsible for the shortened RBC survival in chronic renal failure. 51Cr-labeled RBC survival was elevated in six normal dogs, in six animals with chronic renal failure and seco...

    The realisation that circulating gastrin is heterogeneous necessitates a reappraisal of gastrin's role in the increased incidence of duodenal ulcer disease that occurs in chronic renal failure. Radioimmunoassays employing region-specific antisera have been used to examine renal and extrarenal factors controlling serum gastrin concentration in patients with chronic renal failure. The present study has shown that basal serum gastrin concentrations measured with a carboxyl-terminal specific antibody were significantly higher in eight patients with chronic renal failure treated by dietary restriction (388+/-196 pM) than in 14 patients with chronic renal failure treated by haemodialysis (28.7+/-4.6 pM). However, basal gastrin concentrations in both groups of patients were significantly higher than in 25 normal subjects (12.3+/-1.8 pM) and showed significant negative correlations with maximal gastric acid secretion (p renal failure patients who were also achlorhydric. Although the peak postprandial increment in big gastrin concentration in 11 chronic renal failure patients (34.0+/-7.5 pM) was significantly greater (p exogenous little gastrin was similar in four chronic failure patients (clearance half time: 8.1+/-0.7 min) and four normal subjects (clearance half time: 6.5+/-1.2 min). These studies suggest that the human kidney is unimportant in the metabolism of little gastrin. As circulating little gastrin is six times more potent than big gastrin in stimulating acid secretion, these studies suggest that the raised gastrin concentrations observed in patients with chronic renal failure have little significance in terms of their increased incidence of duodenal ulcer disease.

    Acute renal failure may occur in varied circumstances. It is potentially reversible spontaneously or after specific treatment. It is rare after hunger strike and fewer cases were reported in the literature. The physiopathological mechanisms are varied and remain incompletely known. We report the case of a prisoner having presented an acute renal failure after a hunger strike wich was completely reversible. He's a 29 year old man, without a past medical facts, in July 2004 he was incarcereted in prison. In October 2004 he undertake a hunger strike during one month. In November 2004 he was hospitalized for global dehydration and shock. His physical examination showed blood pressure 60/40 mmHg, weight 59 Kg with a loss of weight about 10 Kg, diuresis 800 cc/day. His biological findings showed urea 100 mmol/l, creatinemia 679 (mo/l, natremia 179 mmol/l, kaliemia 5 mmol/l, glycemia 5.2 mmol/l, albuminemia 35 g/l, calcemia 2.35 mmol/l and biological marques of rhabdomyolysis: CPK at 11 times the normal and LDH two times the normal. His treatment consisted on rehydratation, parenteral then enteral refeeding and psychiatric talks. The evolution was favourable, re-establishment of good hydration state with a gain weight of 7 Kg, normalization of renal function, his creatininemia reached 85 (mol/l in three weeks and normalization of muscles enzymes in one month. Hunger strike continue to pose a problem because of it's frequency in penitentiary structures and its organic disorders which can lead to death. A good psychiatric cares may be undertaked in order to prevent a such bad manifestations.

    MYH9 disorders are autosomal dominant diseases characterized by giant platelets, thrombocytopenia, and granulocyte inclusion bodies. These diseases are caused by mutations in the MYH9 gene that encodes nonmuscle myosin heavy chain IIA. We describe the case of a 27-year-old male who presented with macrothrombocytopenia and leukocyte inclusion bodies. Chronic kidney disease, probably due to progressive glomerulosclerosis, and high-tone sensorineural deafness were evident. Although deterioration of renal function necessitated renal replacement therapy in the form of peritoneal dialysis, we reconsidered the etiology of the kidney disease due to the patient's clinical history. We identified an in-frame deletion mutation in exon 24 of the MYH9 gene that resulted in the removal of 21 nucleotides. The patient was diagnosed with an MYH9 disorder. We report this novel abnormality of the nucleotide sequence and compare it with previous cases and their associated phenotypes.

    1993-09-01

    In patients with chronic renal failure on regular dialysis treatment, limboconjunctival degenerations and calcifications are commonly observed. In this study three groups of patients were followed over a period of 6 years. The first group consisted of 47 patients with renal failure, the second group of 17 patients with renal failure and hyperparathyroidism not controlled by drugs, and the third group seven patients with primary hyperparathyroidism without renal failure. The aim of this study was to determine the progression of the limboconjunctival changes over time. The hypothesis that an increase in serum calcium and phosphorus concentrations, as a result of tertiary hyperparathyroidism, could possibly add a corneal component to the limbal calcification was also tested. All patients with renal failure (in as much as the degenerative limbal features were not obscured by deposits of lime salts), had a type II white limbus girdle of Vogt. This limbal degeneration was observed in only 45% of controls. In all 47 patients with renal failure conjunctival calcification was observed; 26 of them also had limbal calcification. After 6 years 41 patients had developed limbal calcification. This progression was statistically significant. In 15 out of 17 patients with tertiary hyperparathyroidism a band-shaped keratopathy developed in addition to the limboconjunctival calcification.

    Full Text Available OBJECTIVE: The conditions underlying chronic renal failure have become epidemics in the world. The aim of this study was to reveal the degree of awareness of chronic renal failure among family physicians. MATERIAL and METHODS: Using data collected with a structured questionnaire and considering physicians’ socio-demographic features and their education on nephrology, we evaluated physicians’ awareness of the definition, frequency and clinical features of chronic renal failure. The questionnaire was filled in by volunteering family medicine specialists (FMS, family medicine assistants (FMA and family physicians (FP during a family medicine meeting. RESULTS: Out of 310 physicians, 25.2% (n=78 were FMS, 27.7% (n=86 FMA and 47.1% (n=146 FP. %35,2 of physicians (n=109 (FMS: % 62,8 (n=49, FMA: %52.3 (n=45, FP: %10.3 (n=15, p0.05. However, less than 15% of the physicians reported that they felt competent enough to follow patients with chronic renal failure. The rate of the physicians who felt the need to refer these patients to health institutions was high. However, the Fps did not like the patient care style of internal medicine specialists and thought that patients faced financial problems to access the nephrologist. CONCLUSION: Appropriate care and management of referrals are life-saving for patients with chronic renal failure. New strategies should be developed to increase awareness concerning chronic renal failure and the management of this condition.

    Full Text Available Angiotensin converting enzyme inhibitor (ACEI- induced acute renal failure (ARF is not as commonly reported in children as in adults. We report two cases of idiopathic nephrotic syndrome that developed ARF following captopril (an ACEI treatment for prednisolone-induced hypertension. The two cases further alert us to the potential risk of ACEI-induced ARF in any nephrotic child on ACEI treatment. Low or high dose ACEIs should be given with extreme caution in active nephrotics in view of their relative hypovolemic state that may provoke ARF. The nephrotic children, who must be treated with ACEIs with or without diuretics, should be closely monitored for the development of ARF during the use of ACEIs.

  15. Acute renal failure with severe loin pain and patchy renal ischemia after anaerobic exercise in patients with or without renal hypouricemia.

    2002-08-01

    Acute renal failure induced by rhabdomyolysis after strenuous exercise is well known. We describe here a new type of acute renal failure with severe loin pain which develops after anaerobic exercise (ALPE), for example, 200-meter track racing. The patients complained of severe loin pain several hours after exercise and presented at the emergency room. Since our first description 118 cases have been reported. The serum creatinine concentration was 4.7 +/- 2.9 mg/dl (mean +/- SD) at the initial examination and 6.0 +/- 3.0 mg/dl at maximum. Forty-nine of 96 cases whose serum uric acid levels were described revealed renal hypouricemia (51.0%). A specific risk factor is suggested by the fact that acute renal failure recurred after exercise in 20 of 118 cases. The creatine phosphokinase and serum myoglobin concentrations were normal or only slightly elevated, suggesting damaged type 2 muscle fibers. Renal computed tomography scans, performed several hours to 1-2 days after contrast medium administration, revealed multiple wedge-shaped areas of contrast enhancement. Forty-six of 50 cases examined by delayed computed tomography scan revealed bilateral wedge-shaped contrast enhancement. Although less efficient, radioisotopic scans, such as a methylene diphosphonate bone scan, have also been employed to detect patchy accumulation of isotopes in the kidneys (12 of 19 cases). The pathogenesis of ALPE may be patchy vasoconstriction of the renal vessels, because of its wedge-shaped distribution and its reversibility. Such vascular spasm would account for the renal pain. The prognosis was good, although 20 of 109 cases required dialysis treatment. In conclusion, there are two types of exercise-induced acute renal failure: one is the well-known myoglobin-induced acute renal failure, and the other is ALPE that may be nonmyoglobin induced or induced by myolysis of type 2 muscle fibers due to anaerobic exercise. One hundred and eighteen cases of ALPE were collected from the

    Full Text Available Acute renal failure is a frequent entity in the elderly. This is due on one hand to the structural and physiological changes of the aged kidney, and on the other hand to the exposure of this population to polypharmacy and their reduced capability to metabolize drugs. In the present report we present a case of a seventy year-old woman who developed acute renal failure secondary to severe dehydration with a clinical and laboratory pattern of intermediate syndrome: laboratory results compatible with parenchymal renal insufficiency (elevated urinary sodium, plasma urea and creatinine, but with a positive response to hydration. The main characteristics of the aged kidney that predispose to the development of an intermediate syndrome are: the vascular dysautonomy and reduced capability of sodium and water reabsorption. The intermediate syndrome is a typical pattern of pre-renal insufficiency in the elderly. RESUMEN: La insuficiencia renal aguda es frecuente en el anciano. Esto se debe por un lado a los cambios estructurales y funcionales propios del riñón senil, y por otro a la gran exposición que esta población tiene a la polifarmacia, y su reducida capacidad para metabolizar los medicamentos. En este reporte presentamos el caso de una mujer de 70 años que desarrolló una insuficiencia renal aguda secundaria a severa deshidratación, mostrando un patrón clínico y de laboratorio propio de un sindrome intermedio: laboratorios compatibles con una insuficiencia renal parenquimatosa (sodio urinario, uremia y creatininemia elevadas, pero con una respuesta favorable a la hidratación. Las principales características del riñón senil que predisponen al desarrollo del sindrome intermedio: son la disautonomía vascular y la reducida capacidad en la recuperación de sodio y agua El sindrome intermedio es un patrón típico de insuficiencia prerrenal en el anciano.

    The analysis of the scientific literature devoted to organ and tissue changes of oral cavity at the chronic renal insufficiency (CRI)is made. The number of patients in an end-stage of CRI constantly increases and patients receiving renal replacement therapy including hemodialysis, peritoneal dialysis or renal transplantation will comprise an enlarging segment of the dental patient population. Owing to CRI and its treatment there is a set of changes of teeth and oral cavity fabrics which remain even in a end-stage. Renal replacement therapy can affect periodontal tissues including gingival hyperplasia in immune suppressed renal transplantation patients and increased levels of bacterial contamination, gingival inflammation, formation of calculus, and possible increased prevalence and severity of destructive periodontal diseases. Besides, the presence of undiagnosed periodontitis may have significant effects on the medical management of the patients in end-stage of CRI.

  18. RENAL REPLACEMENT THERAPY IN ACUTE KIDNEY FAILURE - AN OVERVIEW

    Directory of Open Access Journals (Sweden)

    Treesa P. Varghese

    2014-10-01

    Full Text Available Renal failure is the loss of renal function, either acute or chronic, that results in azotemia and syndrome of uremia. Acute renal failure, is also known as acute kidney injury (AKI, is defined as an abrupt (within 48 hours reduction in kidney function. The initial management of acute kidney failure involves treating the underlying cause, stopping nephrotoxic drugs and ensuring that the patient is euvolaemic with an adequate mean arterial blood pressure. However, no specific treatments have been shown to reverse the course AKF so Renal Replacement Therapy (RRT is the cornerstone of further management. RRT therapy can be administrated either intermittently or continuously. Multiple modalities of RRT are currently available. The purpose of this review is to familiarize different modalities of RRT for blood purification.

    Increased neurohumoral stimulation resulting in excessive sodium avidity and extracellular volume overload are hallmark features of decompensated heart failure. Especially in case of concomitant renal dysfunction, the kidneys often fail to elicit effective natriuresis. While assessment of renal function is generally performed by measuring serum creatinine-a surrogate for glomerular filtration-, this only represents part of the nephron's function. Alterations in tubular sodium handling are at least equally important in the development of volume overload and congestion. Venous congestion and neurohumoral activation in advanced HF further promote renal sodium and water retention. Interestingly, early on, before clinical signs of heart failure are evident, intrinsic renal derangements already impair natriuresis. This clinical review discusses the importance of heart failure (HF) induced changes in different nephron segments. A better understanding of cardiorenal interactions which ultimately result in sodium avidity in HF might help to treat and prevent congestion in chronic and acute HF.

    Full Text Available Nine cases of tuberculosis (TB were diagnosed among 800 uremic patients, followed-up during 11 years, a prevalence of 1125%, 2.5 times higher than that in the general population. Six patients (66.7% had lymph node involvement (4 cervical and 2 mediastinal. Three patients (33.3% had pulmonary involvement (2 pleuro-pulmonary and 1 bilateral apical pulmonary. Eight patients were undergoing dialysis and 1 was pre-dialytic. The duration of dialysis ranged from 1 to 60 months. Three patients had previously received immunosuppressive drugs for unsuccessful renal transplantation. Daily fever was present in all but one patient; he was asymptomatic and TB was suspected after routine chest radiography. Biopsy was the diagnostic procedure in 7 patients (77.8%, four by direct cervical lymph node biopsy, 2 by mediastinal, performed by mediastinoscopy and 1 by pleural biopsy. In 2 other patients TB was confirmed by the presence of tubercle bacilli; in sputum (1 patient and in a bronchial flushing specimen (the other patient. Triple therapy was used in all patients (isoniazid and ethambutol in all, plus rifampicin in 8 and streptomycin in 1. One patient had jaundice and another had optical neuritis. Five patients were cured. The other four died during treatment of causes unrelated to TB or its treatment.

  1. Progressive renal failure due to renal infiltration by BK polyomavirus and leukaemic cells: which is the culprit?

    2011-02-01

    Renal infiltration with leukaemic cells is a common finding in patients suffering with chronic lymphocytic leukaemia (CLL) but rarely does it lead to significant renal dysfunction. Similarly, BK nephropathy is a recognized cause of graft failure in renal transplant recipients but rarely causes significant disease in native kidneys. In the few reports where leukaemic infiltration of the kidney has led to significant renal impairment, the pathological process causing renal dysfunction is not identified on biopsy. In these cases, it is unclear whether BK polyomavirus (BKV) nephropathy has been excluded. We describe a case of dual pathologies in a patient with Binet stage C CLL and deteriorating renal function where renal biopsy reveals leukaemic infiltration of the kidney occurring alongside BKV nephropathy. The relative importance of each pathology in relation to the rapid decline to end-stage renal failure remains unclear, but the presence of both pathologies appears to impart a poor prognosis. Additionally, we describe the novel histological finding of loss of tubular integrity resulting in tubular infiltration and occlusion by leukaemic cells. It is possible that the patient with advanced CLL is at particular risk of BK activation, and the presence of BK nephropathy may compromise tubular integrity allowing leukaemic cell infiltration and obstruction of tubules. This case bares remarkable resemblance to the first and only other report of its kind in the literature. It is not clear how available immunocytochemistry for polyoma infection is outside transplant centres, and it is possible that BK nephropathy is being under-diagnosed in patients with CLL in the context of declining renal function. At present, the combination of BKV nephropathy and leukaemic infiltration represents a management conundrum and the prognosis is poor. Further research is required in order to better understand the pathological process and therefore develop management strategies.

    Renal injury is an important factor for worsening outcome in acute decompensated heart failure (ADHF). An 81-year-old woman was admitted due to ADHF with dyspnea and mild peripheral edema. The patient was managed with intravenous administration of atrial natriuretic peptide (ANP) at a dose of 0.0125 μg/kg/minute, which did not control volume overload even at an increased dose of 0.025 μg/kg/minute. After a low dose of dopamine (DA) of 1.0 μg/kg/ minute was added, urine output increased markedly to 120 from 30 mL/hour. Furthermore, her heart rate decreased to 80-100 from 120 bpm and the congestion improved with a reduced brain natriuretic peptide level. Interestingly, the combination of ANP and DA therapy reduced serum creatinine as well as the levels of urinary liver-type fatty acid binding protein, a novel reno-tubular stress marker, by 98.9%, and an oxidative stress marker, urinary 8-hydroxydeoxyguanosine, by 88.2% from baseline levels. Thus, this ADHF patient, a nonresponder to ANP alone, improved without renal injury when administered combination therapy consisting of low doses of ANP and DA, suggesting that this combined therapy might be useful for better management of ADHF in patients without diuretic responses with ANP alone. Further prospective studies are warranted.

    Renal infarction (RI) is a rarely seen disorder, and the diagnosis is often missed. The two major causes of RI are thromboemboli originhating from a thrombus in the heart or aorta, and in-situ thrombosis of a renal artery.

    Eight patients aged between 5 and 26 years developed rapid deterioration of renal function and became oliguric/anuric with duration ranging from 1 to 21 days. The initial functional assessment revealed severe degree of glomerular, tubular, and vascular dysfunctions. The magnitude of renal dysfunction was quantified and expressed in terms of a clinical score. The degree of glomerular and tubular dysfunctions were inversely proportional to the renal plasma flow and peritubular capillary blood flow (PTCB), respectively. Similar findings have been observed in a variety of severe glomerulonephropathies. In this aspect, it is likely that the reduction of peritubular capillary blood flow and tubulointerstitial disease are interrelated. Further evidence to support the primary role of reduction of PTCB in inducing tubulointerstitial disease is provided by the following: (a) Reduction of PTCB is documented in mesangial proliferative nephrosis with steroid resistance prior to the detection of tubulointerstitial disease. (b) Ischemic insult can induce tubulointerstitial disease in experimental setting of renal artery occlusion in animal, (c) Improved tubular function can be achieved following the increase in PTCB with the enhanced renal perfusion therapy.

    We report the case of an HIV-positive patient with visceral leishmaniasis and several relapses after treatment with the two first-line anti-leishmanial drugs, liposomal amphotericin B and miltefosine. End-stage renal failure occurred in 2007 when the patient was on long-term treatment with miltefosine. A relapse of leishmaniasis in 2008 was successfully treated with a novel combination regimen of intravenous pentamidine and oral fluconazole. Secondary prophylaxis with fluconazole monotherapy did not prevent parasitological relapse of leishmaniasis.

This article talks about a case of baclofen overdose in a child with renal failure.A 6-year-old boy admitted to the emergency department with a loss of consciousness, hypotonia, and areflexia following administration of 20 mg baclofen (1mg/kg/daily in total dose for his voiding dysfunction. His laboratory tests showed advanced renal failure. After withholding the medication andsupportive therapy, he recovered completely after two days. After arousal, he complained of insomnia, strange sensations on the skin, intentional tremors, and ataxia. He left the hospital in good condition in three days.Renal function control before baclofen administration is mandatory especially in high-risk groups. A total dose of 1mg/kg lead to encephalopathy in children with advanced renal failure, with subtle persistent complaints persist are often overlooked for a while.

    Full Text Available Congenital Hepatic Fibrosis (CHF is a rare disease that affects both the liver and kidneys.  Congenital hepatic fibrosis (CHF is an autosomal recessive inherited malformation defined pathologically by a variable degree of periportal fibrosis and irregularly shaped proliferating bile ducts. Affected individuals also have impaired renal function, usually caused, in children and teenagers, by an autosomal recessive polycystic kidney disease (ARPKD. Impaired renal function associated with CHF in adults is caused by an autosomal dominant polycystic kidney disease (ADPKD. Case presentation: We report the case of a 8-year-old Iranian girlwas admitted to our hospital for evaluation ofrenal failure. In patient hepatomegaly was noted incidentally on a routine physical examination and then kidney biopsy showed global sclerosis and   A liver biopsy revealed proliferation of collagen fibres surrounding the portal area, a finding that was compatible with congenital hepatic fibrosisand our patient was scheduled for kidney and  liver transplantation. Conclusion: The relationship of ARPKD to CHF is the subject of substantial controversy. Some clinicians suggest that the two conditions represent one disorder with a range of clinical/pathological presentations Key word: Congenital Hepatic Fibrosis Polycystic Kidney Disease, CRF.

    `Hematologic malignancies (leukemia, lymphoma, multiple myeloma, et al.), as well as solid tumours (renal, liver, lung, ovarian, etc.), can lead to acute or chronic renal failure.The most common clinical manifestation is acute renal failure within the tumour lysis syndrome (TLS). It is characterized by specific laboratory and clinical criteria in order to prove that kidney disorders result from cytolysis of tumour cells after chemotherapy regimen given, although on significantly fewer occasions it is likely to occur spontaneously or after radiotherapy. Essentially, failure is the disorder of functionally conserved kidney or of kidney with varying degrees of renal insufficiency, which render the kidney impaired and unable to effectively eliminate the end products of massive cytolysis and to correct the resulting disorders: hyperuricemia, hyperkalemia, hypocalcaemia, hyperphosphatemia, and others. The risk of TLS depends on tumour size, proliferative potential of malignant cells, renal function and the presence of accompanying diseases and disorders. Hydration providing adequate diuresis and administration of urinary suppressants (allopurinol, febuxostat) significantly reduce the risk of developing TLS. If prevention of renal impairment isn't possible, the treatment should be supplemented with hemodynamic monitoring and pharmacological support, with the possible application of recombinant urate-oxidase enzyme (rasburicase). Depending on the severity of azotemia and hydroelectrolytic disorders, application of some of the methods of renal replacement therapy may be considered.

  11. Review of Helicobacter pylori infection and chronic renal failure.

    2011-02-01

    Chronic renal failure patients receiving hemodialysis and continuous ambulatory peritoneal dialysis often encounter gastrointestinal troubles over their long treatment period. Helicobacter pylori infection has close association with development of peptic ulcer, gastric cancer and gastric lymphoma, and is thought to be one of the major risk factors for gastrointestinal troubles in dialysis patients. However, it is unclear whether H. pylori infection is directly associated with progression of renal dysfunction and prognosis of chronic renal failure patients. Recent consensus shows that the prevalence of H. pylori infection in chronic renal failure patients is significantly lower than in subjects with normal renal function. In the natural history of H. pylori infection in hemodialysis patients, the prevalence of infection decreases as dialysis periods progressed, in particular within the first four years after the start of treatment. However, the chance of natural eradication becomes rare for patients receiving dialysis treatment for a long time. Moreover, chronic renal failure patients with H. pylori infection have a higher incidence of gastroduodenal diseases, and therefore, are recommended to receive eradication therapies, especially for those receiving treatment for a long time and with higher risks of complication. Intensive endoscopic check-ups for the prevention of gastrointestinal events and the discovery of peptic ulcer and neoplastic diseases at an early phase may be required.

    Necrotizing fascitiis due to Streptococcus Pyogenes has a high mortality rate. Detection of the infection before it developes to the streptococcal toxic shock syndrome is quite challenging and its one of the main goals of its management because at this final stage the treatment is in most of the cases ineffective. In a secuence of events of the progression of the infection to shock, renal failure occurs before hipotension very often. We report the case of a 38-year-old patient affected by a fulminant necrotizing fascitiis by Streptococcus Pyogenes which presented at admission with lower leg cellulitis and acute renal failure.

    Full Text Available Rhabdomyolysis is a syndrome characterized by muscle necrosis which causes the release of myoglobin into the bloodstream. The manifestations of this syndrome range from asymptomatic elevation of serum muscle enzymes to life-threatening cases associated with extremely high enzyme levels, electrolyte imbalance, and acute renal failure. Symptoms of rhabdomyolysis include dark urine, muscle weakness, and fatigue. Statins are commonly used drugs for the prevention and management of dyslipidemia. We present an interesting and critical case on statin-induced rhabdomyolysis with renal failure and previously undiagnosed idiopathic hypothyroidism.

    Full Text Available The powder of henna plant (Lawsonia inermis Linn. is extensively used as a decorative skin paint for nail coloring and as a hair dye. Most reports of henna toxicity have been attributed to adding a synthetic dye para-phenylenediamine (PPD. PPD is marketed as black henna added to natural henna to accentuate the dark color and shorten the application time. PPD toxicity is well known and extensively reported in medical literature. We report a case of a young Saudi male who presented with characteristic features of acute renal failure and intravascular hemolysis following ingestion of henna mixture. Management of PPD poisoning is only suppor-tive and helpful only if instituted early. Diagnosis requires a high degree of clinical suspicion, as the clinical features are quite distinctive.

    Full Text Available Catatonia, originally described by Karl Kahlbaum in 1874, may be regarded as a set of clinical features found in a subtype of schizophrenia, but the syndrome may also stem from organic causes including vascular parkinsonism, brain masses, globus pallidus lesions, metabolic derangements, and pharmacologic agents, especially first generation antipsychotics. Catatonia may include paratonia, waxy flexibility (cerea flexibilitas, stupor, mutism, echolalia, and catalepsy (abnormal posturing. A case of catatonia as a result of acute renal failure in a patient with dementia with Lewy bodies is described. This patient recovered after intravenous fluid administration and reinstitution of the atypical dopamine receptor blocking agent quetiapine, but benzodiazepines and amantadine are additional possible treatments. Recognition of organic causes of catatonia leads to timely treatment and resolution of the syndrome.

  16. Radiological diagnosis of pulmonary edema in chronic renal failure

    Energy Technology Data Exchange (ETDEWEB)

    Tret' yakov, A.E. (Tsentral' naya Klinicheskaya Bol' nitsa, Moscow (USSR))

    Pulmonary edema has been revealed in 132 patients (51.6 %) during radiologic examination of 256 patients with chronic renal failure. The performance of anterio-posterior chest radiographs was in most cases necessary and quite sufficient for making diagnostic conclusions. Follow up study of patients with pulmonary edema and analysis of radiologic picture of the alterations permitted physicians to distinguish approximately 3 stages of the process development, which transit from one into another. Stage 1 involves early disorders and prodromes of pulmonary edema; Stage 2 interstitial lung edema; Stage 3 alveolar edema. The circulation enforcement of the upper lobar vessels has been the main feature of stage 1. Radiogramometry provided additional information for the pulmonary edema diagnosis. For instance, cardioradiometric data are useful for pulmonary edema diagnosis and evidence in favour of its close connection with heart disorders.

    2015-08-01

    Full Text Available Heart failure (HF is a serious debilitating condition with poor survival rates and an increasing level of prevalence. Heart failure is associated with an increase in renal norepinephrine spillover, which is an independent predictor of mortality in HF patients. The excessive sympatho-excitation that is a hallmark of heart failure has long-term effects that contribute to disease progression. An increase in directly recorded renal sympathetic nerve activity has also been recorded in animal models of heart failure. This review will focus on the mechanisms controlling sympathetic nerve activity to the kidney during normal conditions and alterations in these mechanisms during heart failure. In particular the roles of afferent reflexes and central mechanisms will be discussed.

    Science.gov (United States)

    Druml, W

    2014-05-01

    Traditionally, renal dysfunction in congestive heart failure (cardiorenal syndrome type 1) has been attributed to reduced cardiac output and low mean arterial perfusion pressure, which elicit a series of neurohumoral activations resulting in increased renal vascular resistance and decreased renal function.During the last decade, several studies have shown that the extent of renal dysfunction is not so closely associated with indices of forward failure-such as the cardiac index or mean arterial pressure-but rather with indicators of congestion, such as left ventricular enddiasystolic pressure or central venous pressure (CVP), which are indicators of backward failure. The impact of backward failure on renal function is not confined to an elevation of CVP, the renal drainage pressure, but includes a broad spectrum of mechanisms. Involved are the organ systems right heart, lung, the liver, the proinflammatory signals originating from the intestines, but also renal interstitial edema (renal compartment syndrome) and the intraabdominal pressure.The therapeutic measures must focus on the modulation of the preload adapted to the specific situation of an individual patient. This includes diuretics aiming at different segments of the tubulus system including antagonists of aldosteron and ADH, extracorporeal fluid elimination by ultrafiltration or peritoneal dialysis.

    The incidence of chronic renal failure in the elderly is rising due to the ageing of the general population. Its management, and notably nephroprotective therapies, must be adapted to the elderly person who is often frail and with multiple pathologies. The decision to start extra-renal purification does not depend on the patient's chronological age but on their physiological age and requires dialogue between the patient and their family, the geriatrician and the nephrologist.

    We analyzed 19 patients with focal segmental glomerulosclerosis (FSGS): 11 males and 8 females (mean age 38.3 yrs. (SD 16.4), who were under observation for 39.4 months (SD 17.2). At the moment of renal biopsy 73.7% of patients had arterial hypertension, 52.6%--nephrotic proteinuria, 36.9%--chronic renal failure. Global glomerulosclerosis was present in 14 biopsies (73.7%), and intersticial fibrosis--in 13 biopsies (68.4%). The results of analysis showed multiple risk factors for progression of renal failure: initial renal failure (p=0.005), proteinuria (> or =3 g/l) (p=0.005), expressed glomerulosclerosis (p=0.005) and expressed interstitial fibrosis (p=0.034). Focal segmental glomerulosclerosis were found to have a relatively bad long-term prognosis--the renal survival rate in 5 years was 77.8%. Kaplan-Meier survival analysis showed that expressed glomerulosclerosis was risk factor (logrank p=0.016, Breslov p=0.043) associated with end-stage renal disease in 5 years.

    Full Text Available Sudden cardiac death continues to be a major public health problem. Ventricular arrhythmia is a main cause of sudden cardiac death. The present review addresses the links between renal function tests, several laboratory markers, and ventricular arrhythmia risk in patients with renal disease, undergoing or not hemodialysis or renal transplant, focusing on recent clinical studies. Therapy of hypokalemia, hypocalcemia, and hypomagnesemia should be an emergency and performed simultaneously under electrocardiographic monitoring in patients with renal failure. Serum phosphates and iron, PTH level, renal function, hemoglobin and hematocrit, pH, inflammatory markers, proteinuria and microalbuminuria, and osmolarity should be monitored, besides standard 12-lead ECG, in order to prevent ventricular arrhythmia and sudden cardiac death.

    Full Text Available Hymenoptera is a class of insects that sting in order to subdue their prey. Humans coming into accidental contact with these insects results in stings that may cause from mild local reaction like weal formation around the sting site to severe systemic reactions such as intravascular hemolysis, acute renal failure, pulmonary edema, cerebral edema, and rarely pancreatitis. We report here the clinical course of a patient who developed concurrent acute pancreatitis and pigment-induced acute renal failure after multiple hornet stings.

    Duchenne muscular dystrophy (DMD) is a progressive muscular disorder in which respiratory and heart failures are the main causes of death. Intensive intervention in respiratory and cardiac function has dramatically improved the prognosis; however, dysfunction in other multiple organs may emerge in the later stages of the disease. We report the case of four non-ambulatory DMD patients who presented with renal failure. Common findings included decreased fluid intake, use of diuretics, and presence of chronic heart failure. The levels of serum cystatin C (CysC), a marker of kidney function unaffected by reduced muscle mass, were elevated in all four patients. In two patients, renal failure improved by increasing fluid intake, and discontinuing or reducing the dose of diuretics. The findings suggest that non-ambulatory DMD patients are at a risk of reduced kidney perfusion, which potentially leads to prerenal failure. Therefore, in DMD patients, dehydration signs and CysC levels should be monitored.

    Full Text Available Background: The incidence of acute renal failure (ARF in the hospital setting is increasing. It portends excessive morbidity and mortality and a considerable burden on hospital resources. Extracorporeal therapies show promise in the management of patients with shock and ARF. It is said that the potential of such therapy goes beyond just providing renal support. The aim of our study was to analyze the clinical setting and outcomes of critically ill ARF patients managed with continuous renal replacement therapy (CRRT. Patients and Methods: Ours was a retrospective study of 50 patients treated between January 2004 and November 2005. These 50 patients were in clinical shock and had concomitant ARF. All of these patients underwent CVVHDF (continuous veno-venous hemodiafiltration in the intensive care unit. For the purpose of this study, shock was defined as systolic BP < 100 mm Hg in spite of administration of one or more inotropic agents. SOFA (Sequential Organ Failure Assessment score before initiation of dialysis support was recorded in all cases. CVVHDF was performed using the Diapact ® (Braun CRRT machine. The vascular access used was as follows: femoral in 32, internal jugular in 8, arteriovenous fistula (AVF in 4, and subclavian in 6 patients. We used 0.9% or 0.45% (half-normal saline as a prefilter replacement, with addition of 10% calcium gluconate, magnesium sulphate, sodium bicarbonate, and potassium chloride in separate units, while maintaining careful monitoring of electrolytes.

    Full Text Available Introduction. Properly preserved renal perfusion is the basic determinant of oxygenation, vitality, nutrition, and organ function and its structure. Perfusion disorders are functional changes and are ahead of the appearance of biochemical markers of organ damage. The aim of this study was to evaluate a relationship between the renal cortex perfusion and markers of cardiovascular organ damage in patients with stable chronic renal failure (CKD. Methods. Seventeen patients (2 F; 15 M; age 47±16 with stable CKD at 2–4 stages and hypertension or signs of heart failure were enrolled in this study. Blood tests with an estimation of renal and cardiac functions, echocardiographic parameters, intima-media thickness (IMT, renal resistance index (RRI, and total (TPI, proximal (PPI, and distal (DPI renal cortical perfusion intensity measurements were collected. Results. DPI was significantly lower than PPI. TPI significantly correlated with age, Cys, CKD-EPI (cystatin, and IMT, whereas DPI significantly depended on Cystain, CKD-EPI (cystatin; cystatin-creatinine, IMT, NT-proBNP, and troponin I. In multiple stepwise regression analysis model only CKD-EPI (cystatin independently influenced DPI. Conclusions. Cardiovascular and kidney damage significantly influences renal cortical perfusion. Ultrasound measurement of renal perfusion could be a sensitive method for early investigation of cardiovascular and renal injuries.

    Peripartum acute renal failure is an important complication related to pregnancy leading to significant morbidity and mortality. Emphysematous pyelonephritis (EPN) is a severe necrotizing infection of the renal parenchyma, with formation of gas within the collecting system, renal parenchyma, or perirenal tissues. EPN is common in persons with diabetes or urinary tract obstruction. Herein we report a case of bilateral emphysematous pyelonephritis in a postpartum lady who had no evidence of diabetes or urinary tract obstruction. Management of this condition has traditionally been aggressive, and surgery has been considered mandatory. Our patient was managed successfully with antibiotics and supportive measures alone.

    Twin pregnancies are considered at a higher risk for fetal mortality than singleton pregnancies. The antenatal death of one of the twins is associated with an increasing rate of cerebral impairment and lesions in other organs in the surviving fetus, especially if the pregnancy is monochorionic. We describe a case of isolate renal failure becoming evident gradually after birth in a surviving twin after the antenatal death of the co-twin. Considering the deleterious effects of vascular disruption in a surviving twin, our findings suggest careful investigation of renal function, even if no intrauterine signs of diminished renal function were previously detected.

    To analyze the treatment of acute renal failure caused by irrational drug use. Data of 41 cases of acute renal failure seen from July 2008 to June 2012 in our hospital were reviewed. Bilateral renal parenchymas diffuse echo was found enhanced by ultrasound in all cases. Calculus image was not found by X-ray. All children had medical history of using cephalosporins or others. Alkalinization of urine and antispasmodic treatment were given to all children immediately, 17 children were treated with hemodialysis and 4 children accepted intraureteral cannula placement. In 24 children who accepted alkalinization of urine and antispasmodic treatment micturition could be restored within 24 hours, in 11 children micturition recovered after only one hemodialysis treatment and 2 children gradually restored micturition after hemodialysis twice, 4 children who accepted intraureteral cannula immediately restored micturition. In all children micturition recovered gradually after a week of treatment. Ultrasound examination showed that 39 children's calculus disappeared totally and renal parenchymas echo recovered to normal. The residual calculi with diameter less than 5 mm were found in 2 children, but they had no symptoms. The children received potassium sodium hydrogen citrate granules per os and were discharged from hospital. Ultrasound showed calculus disappeared totally one month later. Irrational drug use can cause children urolithiasis combined with acute renal failure, while renal dysfunction can reverse by drug withdrawal and early alkalinization of urine, antispasmodic treatment, intraureteral cannula or hemodialysis when necessary, most calculus can be expelled after micturition recovered to normal.

    Impaired mineral homeostasis and inflammation are hallmarks of chronic kidney disease (CKD), yet the underlying mechanisms of electrolyte regulation during CKD are still unclear. Here, we applied two different murine models, partial nephrectomy and adenine-enriched dietary intervention, to induce kidney failure and to investigate the subsequent impact on systemic and local renal factors involved in Ca(2+) and Pi regulation. Our results demonstrated that both experimental models induce features of CKD, as reflected by uremia, and elevated renal neutrophil gelatinase-associated lipocalin (NGAL) expression. In our model kidney failure was associated with polyuria, hypercalcemia and elevated urinary Ca(2+) excretion. In accordance, CKD augmented systemic PTH and affected the FGF23-αklotho-vitamin-D axis by elevating circulatory FGF23 levels and reducing renal αklotho expression. Interestingly, renal FGF23 expression was also induced by inflammatory stimuli directly. Renal expression of Cyp27b1, but not Cyp24a1, and blood levels of 1,25-dihydroxy vitamin D3 were significantly elevated in both models. Furthermore, kidney failure was characterized by enhanced renal expression of the transient receptor potential cation channel subfamily V member 5 (TRPV5), calbindin-D28k, and sodium-dependent Pi transporter type 2b (NaPi2b), whereas the renal expression of sodium-dependent Pi transporter type 2a (NaPi2a) and type 3 (PIT2) were reduced. Together, our data indicates two different models of experimental kidney failure comparably associate with disturbed FGF23-αklotho-vitamin-D signalling and a deregulated electrolyte homeostasis. Moreover, this study identifies local tubular, possibly inflammation- or PTH- and/or FGF23-associated, adaptive mechanisms, impacting on Ca(2+)/Pi homeostasis, hence enabling new opportunities to target electrolyte disturbances that emerge as a consequence of CKD development.

    Kidney failure is one of the leading causes of disability and death and one of the most disabling features of kidney failure and dialysis is encephalopathy. This is probably caused by the accumulation of uremic toxins. Other important causes are related to the underlying disorders that cause kidney failure, particularly hypertension. The clinical manifestations of uremic encephalopathy include mild confusional states to deep coma, often with associated movement disorders, such as asterixis. Most nephrologists consider cognitive impairment to be a major indication for the initiation of renal replacement therapy with dialysis with or without subsequent transplantation. Sleep disorders, including Ekbom's syndrome (restless legs syndrome) are also common in patients with kidney failure. Renal replacement therapies are also associated with particular neurologic complications including acute dialysis encephalopathy and chronic dialysis encephalopathy, formerly known as dialysis dementia. The treatments and prevention of each are discussed. © Thieme Medical Publishers.

    Simultaneous bilateral spontaneous rupture of the quadriceps tendon is a very rare condition and only a few cases have been reported in the literature. The etiology is not clear yet. But it occurs infrequently in patients with chronic metabolic disorders. A 30-year-old female patient with simultaneous bilateral spontaneous quadriceps tendon rupture visited our hospital. She had chronic renal failure and her parathyroid hormone level was elevated due to parathyroid adenoma. We report a surgical repair of both quadriceps tendons of a patient with chronic renal failure as well as management of hyperparathyroidism.

    Porphyria cutanea tarda (PCT) can occur in HIV patients. Current evidence suggests that HIV infection may interfere with the hepatic cytochrome oxidase system, leading to porphyrin metabolism impairment. Moreover, chronic hemodialysis in renal failure may be a risk factor for PCT. In addition to the contributory factors for PCT associated to HIV infection, it is possible that porphyrin accumulation secondary to renal failure may play a role in the expression of this disease. We report a case of PCT in an HIV-1 infected patient under blood dialysis, refractory to antimalarials and controlled with desferrioxamine.

    Hereditary fructose intolerance is a rare inherited metabolic disorder. Although fructose intolerance usually presents in the paediatric age group, individuals can survive into adulthood by self.manipulation of diet. Hospitalisation can become a high.risk environment for these individuals because of loss of control of their strict dietary constraints and the added danger of administration of medications containing fructose, sucrose and sorbitol. We report a case of hereditary fructose intolerance in an adult presenting with hepatic and renal failure associated with an amiodarone infusion and explore the possibility of polysorbate 80 as a cause of this patient's hepatic and renal failure.

    The mechanism of impaired renal concentrating ability following nonoliguric ischemic acute renal failure was studied in the rat. Fifty min of complete occlusion of the renal artery and vein with contralateral nephrectomy resulted in reversible, nonoliguric acute renal failure. Eight days following induction of acute renal failure, a defect in 30 hr dehydration urine osmolality was present when experimental animals were compared with uninephrectomized controls (1,425 +/- 166 versus 2,267 +/- 127 mOsm/kg water respectively, P less than 0.001). Comparable postdehydration plasma vasopressin levels in experimental and control animals and an impaired hydro-osmotic response to exogenous vasopressin in experimental animals documented a nephrogenic origin of the defect in urine concentration. Lower urinary excretion of prostaglandin E2 in experimental animals and a failure of cyclo-oxygenase inhibition with 10 mg/kg of indomethacin to improve dehydration urine osmolality suggested that prostaglandin E2 antagonism of vasopressin action did not contribute to the concentration defect. Postdehydration inner medullary (papillary) interstitial tonicity was significantly reduced in experimental animals versus controls (870 +/- 85 versus 1,499 +/- 87 mOsm/kg water respectively, P less than 0.001). To determine if this decreased interstitial tonicity was due to vascular mechanisms, papillary plasma flow was measured and found to be equivalent in experimental and control animals. To examine a role for biochemical factors in the renal concentration defect, cyclic nucleotide levels were measured in cytosol and membrane fragments. A decrease in vasopressin and sodium fluoride-stimulated adenylate cyclase was found in outer medullary tissue of experimental animals. In contrast, vasopressin-stimulated adenylate cyclase activity was comparable in the inner medullary tissue of control and experimental animals. Our study suggests a defect in generation of renal inner medullary interstitial

    To assess the diagnostic value of indices measured on a first-pass curve, we performed 72 radionuclide renal first-pass studies (RFP) in 21 patients during the early weeks following renal allograft transplantation. The diagnosis was based on standard clinical and biochemical data and on fine needle aspiration biopsy (FNAB) of the transplant. Aortic and renal first-pass curves were filtered using a true low-pass filter and five different indices of renal perfusion were computed, using formulae from the literature. Statistical analysis performed on the aortic and renal indices indicated excellent reproducibility of the isotopic study. Although renal indices presented a rather large scatter, they all discriminated well between normal and rejection. Three indices have a particularly good diagnostic value. In the discrimination between rejection and Acute Tubular Necrosis (ATN), only one index gave satisfying results. The indices, however, indicate that there are probably ATN with an alternation of renal perfusion and rejection episodes where perfusion is almost intact. We conclude that radionuclide first-pass study allows accurate and reproducible quantitation of renal allograft perfusion. The measured parameters are helpful to follow up the course of a post-transplantation renal failure episode and to gain more insight into renal ischemia following transplantation.

    Full Text Available Background and Objectives: Renal failure patients show significant impairment on measures of attention and memory, and consistently perform significantly better on neuropsychological measures of memory and attention, approximately 24 hours after hemodialysis treatment. The objectives are to determine the cognitive dysfunction in patients with renal failure requiring hemodialysis. Materials and Methods: A total of 60 subjects comprising of 30 renal failure patients and 30 controls were recruited. The sample was matched for age, sex, and socioeconomic status. The tools used were the Standardized Mini-Mental State Examination and the Brief Cognitive Rating Scale. Results: The patients showed high cognitive dysfunction in the pre-dialysis group, in all the five dimensions (concentration, recent memory, past memory, orientation and functioning, and self-care, and the least in the 24-hour post dialysis group. This difference was found to be statistically significant (P=0.001. Conclusion: Patients with renal failure exhibited pronounced cognitive impairment and these functions significantly improved after the introduction of hemodialysis.

    Full Text Available Introduction: Peptide levels in urine are found to be decreased in renal failure. In the current study urinary peptide levels were determined in chronic renal failure (CRF patients. Method: 86 CRF patients and 80 healthy controls were selected for the study. Urinary proteins and peptide levels were determined by spectrophotometer based Lowry and Bradford methods. Urinary creatinine levels were determined by clinical chemistry analyzer. Results: There was significant decrease in urinary peptide levels in CRF patients and Urinary % peptides were significantly decreased in CRF patients as compared to healthy controls. Urinary % peptides correlated negatively with proteinuria. Conclusion: we have found decrease in urinary peptides and % urinary peptides in CRF patients and possibly measurement of % urinary peptides may possibly serve as better indicator in early detection of impairment in renal function.

  12. Peritoneal dialysis in acute renal failure in canines: A review

    Directory of Open Access Journals (Sweden)

    R. H. Bhatt

    Full Text Available Peritoneal dialysis is a technique whereby infusion of dialysis solution into the peritoneal cavity is followed by a variable dwell time and subsequent drainage. During peritoneal dialysis, solutes and fluids are exchanged between the capillary blood and the intraperitoneal fluid through a biologic membrane, the peritoneum. Inadequate renal function leads to disturbance in the removal of the extra fluid and waste products. It removes the waste product and extra fluid from the body in renal failure in small animal practice. Peritoneal dialysis is more accessible, more affordable and easier to administer to the small animal patient. The most common indication for peritoneal dialysis in dogs is acute renal failure (ARF. Peritoneal dialysis is an important therapeutic tool for mitigating clinical signs of uremia and giving the kidneys time to recover in cats with acute kidney injury when conventional therapy is no longer effective.

    Full Text Available Background: Antioxidant depletion occurring in chronic renal failure patients is an important cause of associated morbidity & mortality, which in turn imposes a great socioeconomic burden of health care. Early diagnosis & targeted management of this preventable deficiency may have a positive impact on the management of co morbidities associated with chronic renal failure. Aims & Objectives: To evaluate the status of antioxidants as an early indicator of cardiometabolic risk in chronic renal failure patients. Settings & Design: This was a randomised case Control study including 10 controls of either sex with normal renal function between age group 20-60 years and 15 patients of chronic renal failure on dialysis between the age group of 16 - 60 years. Methods: 12 hour fasting venous blood samples were collected from all the participants and were assayed for various antioxidants. Statistical analysis: Results were analyzed by unpaired t test, p value was determined & Correlation coefficient was calculated amongst various parameters. Results: In the present study, significantly low levels of vitamin C ( Cases: 0.367 ± 0.13 mg/dl controls: 1.324 ± 0.61 mg/dl; p < 0.01 & vitamin E (cases: 0.235 ± 0.102 mg/dl, controls (0.854 ± 0.28 mg/dl; p < 0.01 were observed in chronic renal failure patients as compared to controls. Conclusion: Diminished levels of Vitamin C & E in our study may be an indicator of increased oxidative stress which can be a responsible factor for increased incidence of cardiovascular complications. Supplementing these patients with recommended dosage of these vitamins may provide an essential tool to reduce the burden of suffering. [Int J Res Med Sci 2013; 1(2.000: 87-92

    1988-01-01

    The pharmacokinetics of a single oral dose of roxatidine acetate 150 mg were studied in 31 patients with varying degrees of chronic renal failure. The patients were divided into 5 groups according to their creatinine clearance (Clcr): controls (Clcr 94.5 +/- 13.9 ml/min; n = 6); mild chronic renal failure (Clcr 47 +/- 6 ml/min; n = 4); moderate chronic renal failure (Clcr 27.3 +/- 3.1 ml/min; n = 4); severe chronic renal failure (Clcr 12.8 +/- 1.4 ml/min; n = 5) and uraemia (Clcr 6.6 +/- 0.6 ml/min; n = 12). Serum and urine samples were analysed with capillary gas chromatography to measure the salt of the desacetyl metabolite of roxatidine acetate (roxatidine). The terminal half-life was 6.02 +/- 0.31 hours in controls and 7.35 +/- 0.57, 9.3 +/- 0.83, 14.6 +/- 3.7 and 18.10 +/- 2.77 hours, respectively, in the 4 other groups, with progressively decreasing creatinine clearance. Maximum serum concentration and time to maximum serum concentration rose from 816 +/- 75 ng/ml and 2.08 +/- 0.22 hours, respectively, in controls to 1364.7 +/- 156 ng/ml and 4.05 +/- 0.47 hours, respectively, in uraemic patients. Relative total clearance progressively decreased with decreasing glomerular filtration rate (GFR) [from 353.6 +/- 26 ml/min in controls to 90.31 +/- 12.2 ml/min in patients with uraemia]. Renal clearance decreased from a control of 243.9 +/- 56 ml/min to 12.32 +/- 0.18 ml/min in uraemic patients. A linear correlation between creatinine clearance and both relative total clearance and renal drug clearance was noted.(ABSTRACT TRUNCATED AT 250 WORDS)

    Objective To investigate the common etiologies and their differences in patients with chronic renal failure (CRF) ,thus allowing for guidance of the prevention and treatment. Methods We did a retrospective review on the etiologies of CRF in 937 adults who were treated with hemodialysis and peritoneal dialysis in the in-patient or out-patient clinics, Fourth Affiliated Hospital of China Medical University,between January 2006 and December 2010,for determination of the etiologic features. Results The five leading etiologies of CRF were as follows:chronic glomerulonephritis (26. 15% ) ,diabetic nephropathy (25. 51% ) ,chronic interstitial nephritis (19.64% ) ,hypertensive renal impairment (14. 41% ) and obstructive nephropathy (5. 23% ). The distribution of etiologies varied considerably in different age groups and CKD stages. Our results showed that diabetic nephropathy was the leading cause of CRF in patients aged over 60 years and those at stages CKD3/CKD4 (26. 54% and 27. 57% ,respectively). Whereas chronic glomerulonephritis was the most common etiology of CRF in patients aged less than 59 years and those at stage CKD5 (43. 06% and 29. 84% ,respectively). Conclusion Chronic glomerulonephritis retains its first ranking in the etiology yet incidence of diabetic nephropathy is approaching. In patients with CRF aged over 60 years and those at stages CKD3/CKD4,diabetic nephropathy has become the leading etiology, followed by interstitial nephritis, hypertensive renal impairment and chronic obstructive nephropathy.%目的 探讨慢性肾功能衰竭(CRF)的常见病因并分析其病因变化,为指导CRF的病因诊断和正确防治提供依据.方法 回顾性分析2006年9月至2011年12月在中国医科大学附属第四医院住院、门诊、血液净化中心透析、腹膜透析的937例患者的CRF病因,了解其病因特点.结果 CRF患者的病因构成前5位依次为慢性肾小球肾炎(26.15%)、糖尿病肾病(25.51%)、慢性间质性肾炎(19

    Renal replacement therapy in acute renal failure (ARF) and chronic renal failure (end-stage renal disease; ESRD) has been based on the use of modifications of dialysis (continuous arteriovenous hemofiltration and hemodiafiltration) to remove middle-molecular-weight toxins, consisting of low-molecular-weight proteins and peptides (LMWP) and cytokines involved in inflammation. High-flux dialyzers are not efficient at removing LMWP, and for this reason, sorbents have been studied to augment or replace dialysis. Removal of LMWP such as beta2-microglobulin, leptin, complement factor D, angiogenin and cytokines such as interleukin (IL)-1, IL-6, IL-10, IL-18 and tumor necrosis factor-alpha has been established in animal models of sepsis and in ESRD patients using sorbents. Sorbent devices added to hemodialysis, or the use of such devices alone in inflammatory states, including sepsis, ARF, cardiopulmonary bypass, pre-explantation of donor organs and ESRD, are being studied.

    Renal transplant recipients are at an increased risk of developing Methicillin-resistant Staphylococcus aureus due to their immunosuppressed status. Herein, we investigate the incidence of MRSA infection in patients undergoing renal transplantation and determine the effect of MRSA colonisation on renal allograft function and overall mortality. Between January 1st 2007 and December 31st 2012, 1499 consecutive kidney transplants performed in our transplant unit and a retrospective 1:2 matched case-control study was performed on this patient cohort. The 1-, 3- and 5-year overall graft survival rates were 100%, 86% and 78%, respectively, in MRSA positive recipients compared with 100%, 100% and 93%, respectively, in the control group (P renal allograft failure at 5 years (hazard ratio: 4.6, 95% confidence interval: 1-30.7, P = 0.048). These findings demonstrate that the incidence of long-term renal allograft failure is significantly greater in this patient cohort compared with a matched control population.

    Hemorrhagic fever with renal syndrome (HFRS) is an acute viral disease characterized by fever, hemorrhage and renal failure. Among the various hemorrhagic complications of HFRS, spontaneous rupture of the kidney and perirenal hematoma are very rare findings. We report here on a case of HFRS complicated by massive perirenal hematoma, and this was treated with transcatheter arterial embolization. Hemorrhagic fever with renal syndrome (HFRS) is an acute infectious disease caused by hantavirus. HFRS is clinically characterized by fever, renal failure and hemorrhage in organs such as lung, kidney, spleen and the pituitary gland. Renal medullary hemorrhage is a well-known complication in the kidney, but spontaneous rupture of the kidney and perirenal hematoma in HFRS is rare, and patients showing continuous bleeding and massive perirenal hematoma have often been surgically treated. We report here on a case of HFRS complicated by massive perirenal hematoma, and the patient was treated with transcatheter arterial embolization. In summary, spontaneous rupture of the kidney and perirenal hematoma is a rare complication of HFRS. We report here on a case of HFRS that caused massive perirenal hematoma, and this was treated with superselective renal artery embolization.

  2. Congestive renal failure: the pathophysiology and treatment of renal venous hypertension.

    Longstanding experimental evidence supports the role of renal venous hypertension in causing kidney dysfunction and "congestive renal failure." A focus has been heart failure, in which the cardiorenal syndrome may partly be due to high venous pressure, rather than traditional mechanisms involving low cardiac output. Analogous diseases are intra-abdominal hypertension and renal vein thrombosis. Proposed pathophysiologic mechanisms include reduced transglomerular pressure, elevated renal interstitial pressure, myogenic and neural reflexes, baroreceptor stimulation, activation of sympathetic nervous and renin angiotensin aldosterone systems, and enhanced proinflammatory pathways. Most clinical trials have addressed the underlying condition rather than venous hypertension per se. Interpreting the effects of therapeutic interventions on renal venous congestion are therefore problematic because of such confounders as changes in left ventricular function, cardiac output, and blood pressure. Nevertheless, there is preliminary evidence from small studies of intense medical therapy or extracorporeal ultrafiltration for heart failure that there can be changes to central venous pressure that correlate inversely with renal function, independently from the cardiac index. Larger more rigorous trials are needed to definitively establish under what circumstances conventional pharmacologic or ultrafiltration goals might best be directed toward central venous pressures rather than left ventricular or cardiac output parameters.

    Two cases of diabetes mellitus with renal and retinal involvement developed acute renal failure after undergoing head computerized tomography. The first case was a 62-year-old male who had been diagnosed as having diabetes 25 years before. He had diabetic retinopathy of Scott IIIb. Before head computerized tomography, the serum BUN was 37 mg/dl, and creatinine was 4.1 mg/dl. Oliguria began immediately after the scanning and confinued for 48 hr. The serum levels of BUN and creatinine rose to 106 and 7.7 mg/dl, respectively. Case 2 was a 49-year-old male who had been diagnosed as having diabetes 15 years before. He showed Scott IIb and IV retinopathy. The BUN and creatinine levels in the serum were 32 and 2.3 mg/dl, respectively. After receiving head computerized tomography, he developed oliguria and remained oliguric for 48 hr. During that period, the serum levels of BUN and creatinin were elevated to 112 and 7.5 mg/dl, respectively. Fortunately, both of these patients recovered from the oliguria without resorting to hemodialysis. The iodine contrast medium routinely used for contrast enhancement in the head computerized tomography was implicated in the acute renal failure of these patients. Only eleven cases have so far been reported in the literature who developed acute renal failure following computerized tomography. In view of the three or four times greater dosis of iodine contrast medium employed in computerized tomography compared to intravenous pyelography, the acute incidence of such complications might be much higher. Among the thirteen cases including the two reported here, as many as eight were diabetic. It is well recongnized that the incidence of acute renal failure after intravenous pyelography is particularly high in cases of diabetic nephropathy.

    To investigative clinical and pathological characteristics of IgA nephropathy with chronic renal failure. Clinical and pathological findings from 65 cases of IgA nephropathy with chronic renal failure were reviewed. Pathological characteristics of all the cases were analyzed according to WHO definition and Oxford Classification. Evaluating the severity of pathological lesions by the Katafuchi R semiquantitative scoring system, and analyzing their relationship with clinical indexes of renal function. Of all 65 cases the male and female ratio was 1.4, and the mean age was 37 ± 13 years old. Levels of systolic pressure, mean arterial pressure (MAP), blood urea nitrogen (BUN), serum creatinine (Scr), uric acid (UA), album (Alb), serum IgG and 24 h urinary protein were related with eGRF level (p IgA deposition was the most common immunopathologic type. Of all the cases, 44.6% accompanied with C3 while 4.6% with C1q. Further analysis revealed there were no relationships between severity of pathological lesion and levels of clinical indexes (Scr and eGRF) (p > 0.05). IgA nephropathy with chronic renal failure usually occurred in young adults, and it had severe clinical condition and pathological changes, while there was no significant relationship between them.

    Full Text Available The insertion of indwelling ureteric stents is a routine procedure in urology practice. Complications secondary to the insertion of these stents have also increased, such as stent encrustation, stent fragmentation, stone formation, and recurrent urinary tract infections. Knot formation within the renal pelvis or in the coiled portion of the ureteral stent is an extremely rare condition, with less than 15 cases reported in literature. The authors report a rare case of knotted stent, complicated by an obstructive acute renal failure and urosepsis, in a patient with a solitary functioning kidney.

    Management of diabetic retinopathy should follow more strict and aggressive rules in patients at risk for severe acute renal impairment. Such patients should be identified and possibly prophylactically laser treated to avoid the severe consequences demonstrated in this case report. A 34-year-old type 2 diabetes patient with a stabilized diabetic retinopathy developed acute and severe retinal decompensation within weeks after acute renal failure complicated his chronic stable renal impairment. Fluorescein angiographic and optical coherence tomographic illustrations of the rapid evolution of the retinal condition are presented. The patient had previously been treated with panretinal photocoagulation in his left eye. After 8 years of regular 6-monthly checked stability, he developed rapid-onset proliferative diabetic retinopathy and macular edema in his right eye within 3 months of his last ocular check-up. Fluorescein angiography showed neovessels and major ischemic areas. Emergency panretinal photocoagulation and a sub-Tenon's injection were necessary to achieve control of the situation with regression of neovessels and complete regression of macular edema. This case shows that it is imperative for nephrologists to be well informed about a patient's ocular situation in order to give timely information to the ophthalmologist who can intervene to protect the retina in case of renal failure. On the other hand, the ophthalmologist should be familiar with the renal function of his patient with renal impairment so that he can decide to perform prophylactic retinal panphotocoagulation that should be imperatively considered even without strict indications in patients with renal impairment at risk for further deterioration of renal function, in order to prevent such explosive ischemic and proliferative retinopathy putting vision at risk.

    Objective: To report a comparative clinical and histopathological study on oliguric and non-oliguric acute renal failure (ARF) in malaria. Method: 311 consecutive cases of malaria out of which 74 (23.79%) had ARF as per WHO criteria were conducted. Mean age was 32.58 (range 15-60 years) and male: female was 2:1. Result: Most of the cases developed ARF within 10 d of onset. 18 cases (11 falciparum, 2 mixed, 5 vivax) presented with oliguric and 56 (41 falciparum, 6 mixed, 9 vivax) with non-oliguric renal failure. Associated major manifestations were jaundice (75.68%), cerebral malaria (41.89%), bleeding manifestations (32.43%), severe anemia (27.03%), hypotension (25.68%), multi-organ failure (18.92%), severe thrombocytopenia (12.16%), and ARDS (8.11%). Kidney biopsy (n=20) showed acute tubular necrosis (n=7), Mesangioproliferative glomerulonephritis (n=4) or both (n=9). Hemodialysis was done in 8 cases of oliguric renal failure out of which 4 survived (average no. of session 2.9). Conclusion: Most of the cases recovered within 3 weeks. Total mortality was 28.38% (n=21) and mortality was more in oliguric renal failure (72.22%) as compare to non-oliguric renal failure (14.29%).

    Case (description) the patient is a 20 years old male smoker, who was diagnosed with type 2 diabetes mellitus in 2006. Due to the inadequate response to the previously established treatment, the pharmacotherapy was modified by introducing exenatide (up to 10 μg, twice daily) instead of insulin glargine, but maintaining the treatment with the diuretic and angiotensin II receptor antagonist drugs. Two months later, the patient exhibited a very important intolerance to exenatide (continuous nausea, vomiting, and dehydration), finally leading to ischemic acute renal failure. When the angiotensin II receptor antagonist and exenatide were suspended, a very rapid recovery of renal function was observed. Conclusion ischemic acute renal failure is supposed to be the consequence of the extracellular volume contraction caused by exenatide (the result of continuous nausea and vomiting). This adverse effect could be caused by the co-administration of diuretics and angiotensin II receptor antagonists.

    Full Text Available Elevation of cardiac enzymes and troponins particularly in settings of sepsis and renal failure may cloud the diagnostic picture of acute coronary syndrome in many cases. Interpretation of such elevated enzymes thus warrants caution. It necessitates adequate awareness amongst clinicians, of conditions with such elevation in the absence of myocardial ischemia/infarction as well as those that harbinger false positives. We discuss one such case that posed a diagnostic dilemma and review the pertinent literature.

    We report a case of acute renal failure related to rhabdomyolysis in a patient with Sheehan syndrome, while other diseases that could cause rhabdomyolysis were excluded. The patient's kidney function completely recovered with 3 sessions of intermittent hemodialysis. After thyroxine replacement therapy, musculoskeletal symptoms disappeared and creatine kinase concentrations decreased. Steroid replacement therapy was also administered. The present case suggests that rhabdomyolysis could occur in a patient with Sheehan syndrome without other precipitating factors.

    2006-06-01

    Acute renal failure (ARF) is a common complication in critically ill patients, with ARF requiring renal replacement therapy (RRT) developing in approximately 5 to 10% of intensive care unit (ICU) patients. Epidemiological studies have demonstrated that ARF is an independent risk factor for mortality. Interventions to prevent the development of ARF are currently limited to a small number of settings, primarily radiocontrast nephropathy and rhabdomyolysis. There are no effective pharmacological agents for the treatment of established ARF. Renal replacement therapy remains the primary treatment for patients with severe ARF; however, the data guiding selection of modality of RRT and the optimal timing of initiation and dose of therapy are inconclusive. This review focuses on the epidemiology and diagnostic approach to ARF in the ICU and summarizes our current understanding of therapeutic approaches including RRT.

    Implantable left ventricular assist devices (LVADs) are increasingly being used as a bridge to transplantation or as destination therapy in patients with end stage heart failure refractory to conventional medical therapy. A significant number of these patients have associated renal dysfunction before LVAD implantation, which may improve after LVAD placement due to enhanced perfusion. Other patients develop AKI after implantation. LVAD recipients who develop AKI requiring renal replacement therapy in the hospital or who ultimately require long-term outpatient hemodialysis therapy present management challenges with respect to hemodynamics, volume, and dialysis access. This review discusses the mechanics of a continuous-flow LVAD (the HeartMate II), the effects of continuous blood flow on the kidney, renal outcomes of patients after LVAD implantation, dialysis modality selection, vascular access, hemodynamic monitoring during the dialytic procedure, and other issues relevant to caring for these patients.

    Noordzij, M J; Lefrandt, J D; Smit, A J

    2008-12-01

    The article aims to present an overview of the existing knowledge on advanced glycation end products (AGE). They are moieties that bind to proteins, but also lipids and nuclear acids. AGE are formed during glycation and oxidative stress. Accumulation of AGE occurs especially in diabetes and chronic renal failure and plays a major pathogenetic role. The deleterious effects of AGE result from cross-linking of proteins and activation of the receptor for advanced glycation end products. AGE accumulation can be noninvasively assessed by the skin autofluorescence reader. In diabetics, the skin autofluorescence predicts cardiac mortality and the occurrence of macro- and microvascular complications. In patients on haemodialysis, skin autofluorescence is highly elevated and predicts mortality. After renal transplantation AGE accumulation is lower than during haemodialysis, but still remains elevated and is a strong risk factor for chronic renal transplant dysfunction. Some of the potential methods to intervene with AGE accumulation are discussed in this article.

    Renal cell therapy in conjunction with continuous hemofiltration techniques may provide important cellular metabolic activities to patients with acute renal failure (ARF) and may thereby change the natural history of this disorder. The development of a tissue-engineered bioartificial kidney consisting of a conventional hemofiltration cartridge in series with a renal tubule assist device (RAD) containing 10(9) human renal proximal tubule cells provides an opportunity to evaluate this form of therapy in patients with ARF in the intensive care unit. Nine patients with ARF and multi-organ systems failure (MOSF) have been treated so far with a tissue-engineered kidney in an FDA-approved Phase I/II clinical study currently underway. Acute physiologic parameters and serum cytokine levels were assessed before, during and after treatment with a bioartificial kidney. Use of the RAD in this clinical setting demonstrates maintenance of cell viability and functionality. Cardiovascular stability appears to be maintained during RAD treatment. Human tubule cells in the RAD demonstrated differentiated metabolic and endocrinologic activity. Acute physiologic and plasma cytokine data demonstrate that renal cell therapy is associated with rapid and variable responses in patients with ARF and MOSF. The initial clinical experience with the bioartificial kidney and the RAD suggests that renal tubule cell therapy may provide a dynamic and individualized treatment program as assessed by acute physiologic and biochemical indices.

    Full Text Available Alberto Palazzuoli, Susanna Benincasa, Stefanie Grothgar, Pasquale Di Sipio, Giovanni Paganini, Marco Pellegrini, Ranuccio NutiDepartment of Internal Medicine and Metabolic Diseases, Cardiology Section, Le Scotte Hospital, University of Siena, ItalyAbstract: Chronic kidney disease (CKD is associated with a significant increase in death and cardiovascular mortality. However the exact mechanism by which CKD impairs the cardiovascular outcome is not well established. Some reasons may lie in the association of CKD with several other cardiovascular and noncardiovascular disorders including accelerated systemic atherosclerosis, endothelial dysfunction, increased levels of inflammatory factors, anemic status, bone mineral dysfunction, electrolyte imbalance, and renin–angiotensin–aldosterone system (RAAS activation. Therefore several risk factors such as hypertension, diabetes, lipid disorders, and older age are common in both conditions. In patients affected with heart failure (HF a key role is represented by the neurohormonal activation. This condition causes fluid and sodium retention, peripheral vasoconstriction, as well as increased congestion and cardiac workload. Moreover, HF during the decompensated phases is often associated with a worsening renal function that leads to further RAAS activation, microvascular damage, and intrarenal flow redistribution. In order to clarify the interactions between these factors, several questions need to be answered: the universal definition of “worsening renal function,” the identification of the best laboratory parameters to investigate renal function in terms of sensitivity and specificity, and a better definition of the comorbidities’ role in the determination of the outcome, especially in patients with chronic HF. A clarification of these key points could lead to the individualization of new specific therapeutic targets and to a reduction in mortality and hospitalization in patients with HF and

    Chronic kidney disease (CKD) is a worldwide public health problem. Cardiovascular disease (CVD) is frequently associated with CKD, which is important because individuals with CKD are more likely to die from CVD than to develop kidney failure. CVD in CKD is treatable and potentially preventable and CKD appears to be a risk factor for CVD. In order of incidence and frequency systemic hypertension, left ventricular failure, congestive cardiac failure, ischemic heart disease, anaemic heart failure, rhythm disturbances, pericarditis with or without effusion, cardiac tamponade, uraemic cardiomyopathy are various cardiovascular complications encountered in patients with chronic renal failure. A patient may present with one or more complications of cardiovascular system. The survival rate and prognosis to a great extent depends on proper management of these complications. Use of regular dialysis and renal transplant has changed the death pattern in developed countries but it is still a major problem in developing country. The aim of this article is early detection of CKD and proper management of it thereby preventing the major cardiovascular complications.

    The information available on the incidence and the characteristics of patients with acute renal failure (ARF) related to drugs is scarce. To estimate the incidence of drug-related ARF in hospitalised patients and to compare their characteristics with those of patients with ARF due to other causes. We selected a prospective cohort of patients with ARF during hospital admission (July 2010-July 2011). Information on patients' demographics, medical antecedents, ARF risk factors, ARF severity according to the RIFLE classification and hospital drug administration was collected. We analysed the relationship of drugs with the ARF episodes using Spanish Pharmacovigilance System methods and algorithm. A total of 194 cases had an episode of hospital-acquired ARF. The median age of patients was 72 years [IQR 20]; 60% were men. The ARF incidence during hospitalization was 9.6 per 1,000 admissions. According to the RIFLE classification, a risk of kidney damage or kidney injury was present in 77.8% of cases. In 105 (54.1%) cases, ARF was drug-related; the drugs most frequently involved were diuretics, agents acting on the renin-angiotensin system, immunosuppressants, β-blocking agents, calcium channel blockers, contrast media and non-steroid anti-inflammatory drugs. Patients with drug-related ARF had more multi-morbidity, fewer ARF risk factors and lower mortality. Half of ARF episodes during hospitalisation were drug related. Patients with drug-related ARF had higher cardiovascular morbidity than those with ARF related to other causes, but they had a lower frequency of ARF risk factors and mortality.

    Plasma renin activity, plasma aldosterone levels and renal tubular capacity to excrete hydrogen ions were studied in 13 patients suffering from diabetes mellitus with a creatinine clearance of less than 40 ml/min. The results were compared with those obtained in a control group, in a group of nondiabetic subjects with chronic renal failure (CRF) and in a group of diabetic patients without CRF. Twelve of the thirteen diabetic patients with CRF had data characteristic of hyporeninemic hypoaldosteronism associated with type IV renal tubular acidosis. On comparing the results with those of the other two groups of patients, it was observed that the manifestations of the latter two groups considered separately were different from those of the problem group, although in the diabetic patients with normal glomerular filtration rate (GFR) hyporeninism but not hypoaldosteronism was present accompanied by a lower net acid excretion (p less than 0.001) due to a lower excretion of NH4 (p less than 0.05) and titratable acid (p less than 0.001) when the patients were challenged with an NH4Cl overload. We believe that a conjunction of diabetes and renal failure is necessary for the diabetic patients with a decrease in GFR to show hyporeninemic hypoaldosteronism and type IV tubular acidosis.

    The purpose of the study was to investigate the coping behaviours of Chinese patients with chronic renal failure. The study, based on Lazarus and Folkman (Stress, Appraisal and Coping, Springer, New York, 1984) model of coping, was conducted to identify the process by which 11 chronic renal failure patients cope with their disease. The identified themes are coping with fluctuating feelings and concerns, motivation to cope, interdependent relationships between patients and their family members and modes of coping strategies. The significance of the results indicates that coping is the consequence not only of situational demands but also of life goals. Meaning in life is an important motivator in the coping process. Besides problem-focused coping and emotion-focused coping, another important element is relationship-focused coping. The interdependent influences of families on patients and patients on families are also important factors. The role of family and cultural factors is discussed as it affects how patients with chronic renal failure cope with their illness.

    Full Text Available Refugee camps are prone for easy spread of infections of various kinds and tuberculosis (TB is no exception. Refugees with renal failure are often a vulnerable group because they are immunocompromised due to reasons such as poor nutrition, overcrowding and immune suppression due to renal failure. Latent pulmonary TB is a particular problem in this patient population as it is not easily diagnosed and has immense potential for spread. Tuberculin Skin Test (TST, although easy to perform and is cost-effective, suffers from the limitations of giving false positive results due to cross-reaction with the vaccination. Chest radiography though cheap, has not yet been validated in refugee populations for this purpose. Sputum analysis shows promise due to ease of performing but again has not been validated in refugees. Newer assays such as IF-γ show great promise but needs large scale studies for validation and cheaper assays need to be developed for use in resource poor refugee setting. In short, an ideal tool for effective screening of latent TB in refugees with renal failure is lacking. Future studies are required to identify this ideal tool.

  7. Renal malakoplakia presenting as a renal mass in a 55-year-old man: a case report

    Full Text Available Abstract Introduction Malakoplakia is an uncommon chronic inflammatory condition that has a gross and microscopic appearance resembling that of xanthogranulomatous pyelonephritis. It is characterized by distinctive Michaelis-Gutmann bodies. Malakoplakia can affect any organ system but genitourinary tract involvement is the most common, particularly in immunocompromised individuals. Very rare cases have been reported to present as a unifocal lesion mimicking a renal tumor. Case presentation We report a case of renal malakoplakia in a 55-year-old Iranian man with a past history of recurrent urinary tract infections who presented with left flank pain. An ultrasound study showed a large solid left renal mass, and he underwent a left radical nephrectomy with a clinical diagnosis of a renal tumor. Pathology slides revealed the diffuse infiltration of sheets of Periodic Acid Schiff-positive histiocytes in his renal parenchyma; these cells showed strong immunoreactivity for CD 68. The final diagnosis was renal malakoplakia. Conclusion Renal malakoplakia must be kept in mind for patients presenting with a renal mass and a history of long-term recurrent renal infections or renal failure. The large, rapidly growing nodules of malakoplakia may mimic renal cell carcinoma in imaging studies. In these cases, a true cut needle biopsy may help the correct diagnosis and prevent unnecessary surgery.

    Renal dysfunction (RD) is a frequent comorbid condition and a major determinant of outcomes in patients with heart failure (HF). It is likely that the etiology of RD in patients with HF is much more complex than we first thought and represents a matrix of independent, albeit interacting, pathophysiological pathways with effects on both the kidney and the heart that share a common denominator: aging and inflammation. Renal dysfunction in HF has been attributed, among others, to biochemical, hormonal, and hemodynamic factors, coupled with pharmacological interventions. Regardless of the cause, the development of RD or worsening renal function is common in patients with HF, and is associated with increased morbidity and mortality. There is increasing evidence, however, that transient increases in creatinine in the setting of acute HF are not prognostically important, whereas persistent deterioration does portend a higher mortality in this patient population. In addition, congestion seems to play an important role in the course of renal deterioration, and the combination of congestion and worsening renal function is the most significant clinical prognosticator in HF patients. This review aims to provide an update on the epidemiology and prognostic significance of RD in HF patients, in both the acute and the chronic setting.

    1. Adenosine (ADO) can induce renal vasoconstriction and a fall in glomerular filtration rate. When the rate of ATP hydrolysis prevails over the rate of ATP synthesis the kidney generates ADO at an enhanced rate. 2. Tubuloglomerular feedback (TGF) is the vascular response to changes of the NaCl concentration in the tubular fluid at the macula densa segment, which is the result of transepithelial electrolyte reabsorption by the proximal tubule and the loop of Henle. 3. TGF can be inhibited by ADO-A1 receptor antagonists and is potentiated by substances that can elevate extracellular ADO concentrations. These observations led to the hypothesis that ADO is an element of the signal transmission processes in the juxtaglomerular apparatus. 4. Renal ischaemia and nephrotoxic substances can induce acute renal failure (ARF). ADO receptor antagonists have been shown to ameliorate renal function in several different models of ARF in laboratory animals and humans. 5. A number of factors, such as extracellular volume contraction, low NaCl diet, angiotensin II and cyclooxygenase inhibitors enhance to a similar extent: (a) the renal vascular response to endogenous and exogenous ADO; (b) the TGF response of the nephron; and (c) the severity of ARF. All three phenomena are susceptible to antagonism by ADO receptor antagonists. 6. Therefore, we conclude that ADO plays a significant role in normal and pathological states of kidney function.

    Renal failure is common in heart failure due to renovascular constriction and hypotension. We tested whether selective pharmacological renal artery vasodilation and active renal artery perfusion (ARP) could improve renal function without adverse effects on systemic blood pressure in a canine model of acute heart failure (AHF). AHF was induced by coronary microembolization in 16 adult mongrel dogs. In five dogs, selective intrarenal (IR) papaverine (1, 2, and 4 mg/min) was administered into the left renal artery. In six dogs, ARP was performed in the left renal artery to normalize mean renal arterial pressure followed by administration of IR papaverine (2 mg/min). In five dogs, ARP plus intravenous furosemide was tested. Urine output (UO) and cortical renal blood flow decreased during AHF and were restored by 2 mg/min IR papaverine (UO: baseline 4.2 +/- 0.6, AHF 1.6 +/- 1.3, IR papaverine 5.8 +/- 1.1 ml/15 min; cortical blood flow: baseline 4.3 +/- 0.2, AHF 2.4 +/- 0.6, IR papaverine 4.2 +/- 1.2 ml/min/g) with no significant change in aortic pressure. ARP also increased urine output and cortical renal blood flow (UO: baseline 5.0 +/- 1.1, AHF 0.5 +/- 0.4, ARP 3.8 +/- 3.1 ml/15 min; cortical blood flow: baseline 4.0 +/- 0.5, AHF 2.0 +/- 0.8, ARP 3.52 +/- 1.1 ml/min/g). A combination of these methods in AHF further increased urine output to twice the normal baseline (10.5 +/- 7.5 ml/15 min). Addition of furosemide synergistically increased UO above that achieved with ARP alone (5.5 +/- 2.6 versus 40.3 +/- 24.7 ml/15 min, p = 0.03). In conclusion, ARP and selective renal vasodilation may effectively promote salt and water excretion in the setting of heart failure, particularly when systemic blood pressure is low.

    There is great debate as to whether the benefit gained from the knowledge of renal histology outweighs the risk to the patient from the biopsy procedure. We conducted a prospective study of 276 native renal biopsies performed on 266 patients from a single centre in 1991 to assess the effect of the knowledge of renal histology on patient management. Biopsies were performed under ultrasound guidance using the Trucut biopsy needle. The indications for biopsy were: non-nephrotic proteinuria alone (25), haematuria and proteinuria (28), nephrotic range proteinuria (28), acute renal failure (31), haematuria alone (36), and chronic renal failure (128). Two hundred and sixty-three biopsies were successful. The mean number of glomeruli obtained was 23, range 0-115. Eight patients developed macroscopic haematuria of which two required blood transfusion. The result of the biopsy altered management in 24/28 (86%) of cases of nephrotic range proteinuria, 22/31 (71%) of cases of acute renal failure, 58/128 (45%) of cases of chronic renal failure, 9/28 (32%) of cases with haematuria and proteinuria, 3/25 (12%) of cases with non-nephrotic proteinuria alone, and 1/36 (3%) of cases with haematuria alone. management was altered in 42% of cases overall. These data suggest that knowledge of renal histology is essential in the management of patients with renal disease.

    Full Text Available Two clinical cases of patients who survived after numerous attacks of Africanized bees (600 and 1500 bee stings, respectively are reported. Clinical manifestation was characterized by diffuse and widespread edema, a burning sensation in the skin, headache, weakness, dizziness, generalized paresthesia, somnolence and hypotension. Acute renal failure developed and was attributed to hypotension, intravascular hemolysis, myoglobinuria due to rhabdomyolysis and probably to direct toxic effect of the massive quantity of injected venom. They were treated with antihistaminic, corticosteroids and fluid infusion. One of them had severe acute renal failure and dialysis was required. No clinical complication was observed during hospital stay and complete renal function recovery was observed in both patients. In conclusion, acute renal failure after bee stings is probably due to pigment nephropathy associated with hypovolemia. Early recognition of this syndrome is crucial to the successful management of these patients.Foram relatados dois casos clínicos de pacientes que sobreviveram a ataques maciços de abelhas africanizadas (600 e 1500 picadas. As reações caracterizaram-se por edema difuso e generalizado, sensação de queimação na pele, cefaléia, fraqueza, parestesia generalizada, sonolência e hipotensão. A insuficiência renal aguda desenvolveu-se, tendo sido atribuída à hipotensão, hemólise intravascular, mioglobinúria devido à rabdomiólise e provavelmente ao efeito tóxico direto da grande quantidade de veneno injetada. Os pacientes foram tratados com agentes anti-histamínicos, corticosteróides e reposição hídrica. Um paciente apresentou quadro grave de insuficiência renal aguda necessitando de tratamento dialítico. Nenhuma complicação clínica foi observada durante a internação e ambos evoluíram bem com recuperação completa da função renal. Assim, a insuficiência renal aguda após picadas de abelhas ocorre provavelmente

    Primary renal lymphoma is a controversial entity. Only 29 cases have been reported since 1980. Diagnostic criteria are not well established. We report here 3 new cases and review the literature. Primary renal lymphoma was considered on the basis of uni- or bilateral nonobstructive nephromegaly with or without renal failure. In all cases, the diagnosis was made after renal biopsy. Extrarenal abdominal involvement was excluded by imaging techniques. The role of staging laparotomy remains controversial. Chemotherapy is the treatment of choice, but the prognosis is poor. We propose a clinical definition of primary renal lymphoma in order to achieve a better management of the disease.

    Renal enlargement at time of diagnosis of acute leukemia is very unusual. We here in report 2 pediatric cases of acute leukemia who had their renal affection as the first presenting symptom with no evidences of blast cells in blood smear and none of classical presentation of acute leukemia. The first case is a 4-year-old girl who presented with pallor and abdominal enlargement. Magnetic resonance imaging showed bilateral symmetrical homogenous enlarged kidneys suggestive of infiltration. Complete blood picture (CBC) revealed white blood count 11 × 10⁹/L, hemoglobin 8.7 g/dL and platelet count 197 × 10⁹/L. Bone marrow aspiration was performed, and diagnosed precursor B-cell ALL was made. The child had an excellent response to modified CCG 1991 standard risk protocol of chemotherapy with sustained remission, but unfortunately relapsed 11 month after the end of therapy. The second child was 13-month old, presented with pallor, vomiting, abdominal enlargement, and oliguria 2 days before admission. Initial CBC showed bicytopenia, elevated blood urea, creatinine, and serum uric acid, while abdominal ultrasonography revealed bilateral renal enlargement. Bone marrow examination was done and showed 92% blast of biphenotypic nature. So, biphynotypic leukemia with bilateral renal enlargement and acute renal failure was subsequently diagnosed. The patients admitted to ICU and received supportive care and prednisolone. Renal function normalized and chemotherapy was started. The child achieved complete remission with marked reduction of kidney size but, unfortunately she died from sepsis in consolidation phase of therapy. This case demonstrates an unusual early renal enlargement in childhood acute leukemia. Renal involvement of acute leukemia should be considered in child presenting with unexplained bilateral renal enlargement with or without renal function abnormalities and bone marrow examination should be included in the workup.

    Rheumatoid arthritis (RA) is one of the commonest rheumatological diseases. Renal involvement is not common but can occur as a result of chronic inflammation as part of disease process or drug toxicity. Thrombotic microangiopathy (TMA) is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and organ failure of variable severity. Only a few cases of TMA in patients with RA were reported to date. We describe a 45-year-old female patient with RA who presented with oliguria and edema. Renal biopsy showed TMA with patchy cortical necrosis. She improved with hemodialysis and plasmapheresis. PMID:28182045

    Therapy of prolonged acute renal failure regularly requires a renal replacement therapy. This can be achieved by different extracorporal renal replacement therapies (ERRT) or by peritoneal dialysis. ERRT are classified according to the physical principle underlying toxin elimination as hemodialysis (diffusion) and hemofiltration (convection). Another classification refers to intermittent or continuous application modes. Biocompatibility of membranes is judged according to their activation of the complement system. Prospective randomized studies did not consolidate the assumptions about the benefit of particular modalities proposed on theoretical foundations. Mortality, duration and complication rates of acute renal failure are not significantly decreased by use of biocompatible membranes. Continuous modalities are not generally preferable but optimize treatment in hemodynamically unstable patients, in whom they endorse fluid balancing and maintenance of sufficient arterial blood pressure. The use of demanding hemofiltration techniques for cytokine removal should be limited to clinical studies. The effects of ERRT-"intensity" and the best timing for initiation of ERRT have not been evaluated sufficiently. The choice of the ERRT modality is subject to clinical judgement (criterion: hemodynamic situation), practical aspects (criteria: availability of equipment and handling experience), and costs. Prior to their general use new and expensive technical modalities and membrane types should be thoroughly evaluated in studies with regard to outcome-related aspects such as patient survival and preservation of renal function.

    Full Text Available A patient with miliary tuberculosis and a chronic urogenital focus is described, who had a borderline renal function at diagnosis and developed overt renal failure upon daily treatment with rifampin (RMP, isoniazid (INH and ethambutol (EMB. This is the first Brazilian report of BMP induced renal damage. A renal biopsy taken on the third day of oliguria showed recent tubular necrosis with acute interstitial inflammation and granuloma formation. The aspect of the granulomatous lesion hightly suggested drug etiology because of the lack of palisading, high incidence of neutrophils and absence of facid-fast bacilli. This is the first presentation of an acute granulomatous interstitial nephritis probably due to RMP. Furthermore the pathogenesis of the renal damage caused by tuberculosis and RMP are discussed.Apresentamos um paciente com tuberculose miliar a partir de um foco crônico urogenital. Em sua entrada no hospital tinha uma função renal limítrofe e desenvolveu franca insuficiência renal na vigência da terapêutica específica constituída por RMP, INH e EMB. Bióp-sia renal realizada no 3° dia de uremia revelou necrose tubular recente, com inflamação intersticial aguda, permeada por granulomas. As formações granulomatosas foram altamente sugestivas de reação alérgica à droga devido à ausência de paliçadas, alta incidência de neutrófilos e o não encontro de bacilos-álcool-ácido-resistentes. Esta é a primeira descrição de nefrite intersticial granulomatosa provavelmente causada pela RMP. São discutidos os principais aspectos fisiopatogênicos da insuficiência renal causada pela tuberculose acrescida dos efeitos nefrotóxicos da RMP.

    The extent to which hypothyroidism affects renal function in patients with heart failure remains incompletely explored, despite the known adverse prognostic implications of renal dysfunction in these patients.In a pilot retrospective study, we evaluated 75 patients (age, >or=18 yr) with left ventricular ejection fractions 5.5 micro IU/mL). Renal function, measured in terms of glomerular filtration rate, was analyzed once in each patient, and the populations were statistically compared, with P <0.05 conferring statistical significance.Baseline characteristics in all groups were similar. Mean glomerular filtration rate was better in patients with normal thyroid function than those with hypothyroidism (75.45 +/- 31.48 vs 63.95 +/- 21.43 mL/min/1.73 m2; P=0.032). There was no significant difference between patients with controlled hypothyroidism (66.89 +/- 24.18 mL/min/1.73 m2) and those with normal thyroid function (P=0.131). In patients with uncontrolled hypothyroidism, mean glomerular filtration rate (60.2 +/- 17.4 mL/min/1.73 m2) was significantly worse than in patients with normal thyroid function (P=0.015).We found that heart-failure patients with insufficiently treated hypothyroidism have worse renal function than do patients whose thyroid function is normal or whose hypothyroidism is effectively treated. Larger studies will be needed in order to evaluate this conclusion further. We recommend that hypothyroidism in heart-failure patients be strictly controlled, lest it affect prognosis adversely.

    We report a case of a healthy 24-year-old man who presented with acute renal failure and proteinuria while taking creatine and multiple other supplements for bodybuilding purposes. A renal biopsy showed acute interstitial nephritis. The patient recovered completely after he stopped taking the supplements. Creatine is a performance-enhancing substance that has gained widespread popularity among professional as well as amateur athletes. It is legal and considered relatively safe. Recently there have been case reports of renal dysfunction, including acute interstitial nephritis, associated with its use. Further studies are needed to evaluate the safety of creatine supplementation. It may be prudent to include a warning of this possible side effect in the product insert.

    Systemic hypertension is hypothesized to cause renal injury to dogs. This study was performed on dogs with surgically induced renal failure to determine whether hypertension was associated with altered renal function or morphology. Mean arterial pressure (MAP), heart rate (HR), systolic arterial pressure (SAP), and diastolic arterial pressure (DAP) were measured before and after surgery. Glomerular filtration rate (GFR) and urine protein:creatinine ratios (UPC) were measured at 1, 12, 24, 36, and 56-69 weeks after surgery, and renal histology was evaluated terminally. The mean of weekly MAP, SAP, and DAP measurements for each dog over the 1st 26 weeks was used to rank dogs on the basis of MAP, SAP, or DAP values. A statistically significant association was found between systemic arterial pressure ranking and ranked measures of adverse renal responses. When dogs were divided into higher pressure and lower pressure groups on the basis of SAP, group 1 (higher pressure, n = 9) compared with group 2 (lower pressure, n = 10) had significantly lower GFR values at 36 and 56-69 weeks; higher UPC values at 12 and 56-69 weeks; and higher kidney lesion scores for mesangial matrix, tubule damage, and fibrosis. When dogs were divided on MAP and DAP values, group 1 compared with group 2 had significantly lower GFR values at 12, 24, 36, and 56-69 weeks; higher UPC values at 12 and 56-69 weeks; and higher kidney lesion scores for mesangial matrix, tubule damage, fibrosis, and cell infiltrate. These results demonstrate an association between increased systemic arterial pressure and renal injury. Results from this study might apply to dogs with some types of naturally occurring renal failure.

    Aim:The aim of the present study was to investigate the effectiveness of trans-forming growth factor (TGF)-β1 antisense oligodeoxynucleotides (ODN) in ame-liorating deteriorated kidney function in rats with puromycin-induced chronic renal failure (CRF). Methods:Saline, puromycin, puromycin+TGF-β1 antisense ODN or puromycin+scrambled ODN were administered to unilaterally nephrecto-mized rats. Renal hemodynamic and excretory measurements were taken in the anaesthetized rats that had undergone surgical procedure. Results:It was ob-served that in the CRF rats, there was a marked reduction in the renal blood flow (RBF), glomerular filtration rate (GFR), severe proteinuria, and almost 6-fold in-creased fractional excretion of sodium (FE Na+) as compared to that in the control rats (all P<0.05). It was further observed that in the CRF rats, the treatment with TGF-β1 antisense, but not scrambled ODN, markedly attenuated the reduction of RBF, GFR, and proteinuria and markedly prevented the increase of the FE Na+ (all P<0.05). In addition, the renal hypertrophy in the CRF group (P<0.05 vs non-renal failure control) was markedly attenuated after treatment with TGF-1 antisense ODN (P<0.05). Focal segmental glomerulosclerosis was evident only in the un-treated and scrambled ODN-treated CRF groups. An interesting observation of this study was that in the CRF rats, although there was marked attenuating and preventive effects of the TGF-β1 antisense ODN on the deteriorated renal functions, the antisense treatment did not cause any marked change in the renal expression of TGF-β1 at the protein level. Conclusion:Collectively, the data obtained sug-gests that TGF-β1 antisense ODN possesses beneficial effects in puromycin-induced chronic renal failure and that the deterioration in morphology and im-paired renal function in this pathological state is in part dependent upon the action of TGF-β1 within the kidney.

    Full Text Available Several studies show the ability of macrophages to remove particles injected into the bloodstream. This function seems to be increased in the presence of acute renal failure. The objective of the present study was to assess the phagocytic function of the main organs (spleen, liver and lung of the mononuclear phagocytic system in renal and postrenal failures. Fifteen rats (250-350 g were divided into three groups (N = 5: group I - control; group II - ligature of both ureters, and group III - bilateral nephrectomy. On the third postoperative day, all animals received an iv injection of 1 ml/kg 99mTc sulfur colloid. Blood samples were collected for the assessment of plasma urea, creatinine, sodium, and potassium concentrations and arterial gasometry. Samples of liver, spleen, lung and blood clots were obtained and radioactivity was measured. Samples of liver, spleen, lung and kidney were prepared for routine histopathological analysis. Plasma urea, creatinine and potassium concentrations in groups II and III were higher than in group I (P<0.05. Plasma sodium concentrations in groups II and III were lower than in group I (P<0.05. Compensated metabolic acidosis was observed in the presence of postrenal failure. Group II animals showed a lower level of radioactivity in the spleen (0.98 and lung (2.63, and a higher level in the liver (105.51 than control. Group III animals showed a lower level of radioactivity in the spleen (11.94 and a higher level in the liver (61.80, lung (11.30 and blood clot (5.13 than control. In groups II and III liver steatosis and bronchopneumonia were observed. Renal and postrenal failures seem to interfere with blood clearance by the mononuclear phagocytic system.

    Full Text Available To determine the incidence of acute renal failure (ARF and nephrosonographic findings among asphyxiated neonates, and to correlate this with uric acid levels and the severity of hypoxic encephalopathy, we studied 80 full-term appropriate-for-date singleton neonates with perinatal asphyxia, and 30 healthy full-term neonates as controls from March 2006 to February 2007. A detailed history, thorough clinical examination along with investigations, including urine examination, 24-h urine collection, ultrasonography of abdomen and cranium, serum electrolytes, blood urea nitrogen, serum creatinine, and serum uric acid were obtained. ARF developed in 45% (36/80 of the asphyxiated neonates. Forty-eight (60% neonates showed significant elevation of blood urea and 41 (51.3% neonates had significant elevation of serum creatinine than the control group (P < 0.001. Sixty-two (77.5% neonates developed significant elevation of serum uric acid levels, and nephrosonography revealed hyperechogenicity in all of them, while only two among the healthy neonates showed the raised uric acid levels (P < 0.001. Nonoliguric renal failure was seen 28/36 (77.8% of the neonates with ARF, whereas eight (22.2% neonates had oliguric renal failure. Eight (27.8% patients among ARF patients maintained abnormal biochemical parameters after 2 weeks, and of whom four patients died after variable lengths of time with a mortality rate of 11.11%. Kidneys are the most common organs involved in perinatal asphyxia, and uric acid might be a causative factor for failure in addition to hypoxic insult. Routine use of kidney function test, along with abdominal ultrasonography form an important screening tool to detect any additional morbidity in these patients.

    Imaging techniques, especially ultrasonography and Doppler, can give an effective assistance in the differential diagnosis of acute renal failure (ARF). An resistance Index (RI) value >0.75 is reported as optimal in attempting differential diagnosis between acute tubular necrosis (ANT) and prerenal ARF. In hepatorenal syndrome (HRS) RIs is very increased. In some renal vasculitis, as nodose panarteritis (PN), hemolytic-uremic syndrome (HUS), thrombotic thrombocytopenic purpura (TTP), parenchymal perfusion is reduced and RI increased. In lupus nephritis the RI values are correlated with creatinine level and normal RI are considered as a good prognostic tool. In acute primitive or secondary glomerulonephritis (GN), RI value is normal, with diffuse parenchymal hypervascularization. In acute crescentic and proliferative GN and tubulo-interstitial disease, color Doppler (CD) and power Doppler (PD) reveal a decreased renal parenchymal perfusion, which correlates with increased RI values. In acute thrombosis of renal artery, US color Doppler (DUS) reveals either an absence of Doppler signal or a tardus-parvus pulse distal to the vascular obstruction. In this situation it is possible to visualize hyperthropic perforating vessels that redirect their flow from the capsular plexus to the renal parenchyma. In acute thrombosis of the renal vein Doppler analysis of parenchymal vessels reveals remarkable RI values, sometimes with reversed diastolic flow. In postrenal ARF an adjunct to the differentiation between obstruction and non obstructive dilatation can be found through RIs. Diagnostic criteria of obstruction as reported by literature are: RI>0.70 in the obstructed kidney and, mostly, a difference in RI between the 2 kidneys >0.06-0.1.

    8 patients suffering from acute renal failure (shock kidney) with anuria extending over 3 to 5 days, were treated with L-thyroxine for 5 to 9 days (5-6 mug per kg body weight per day orally). Diuresis was restored within 34 to 46 hrs. Plasma levels of urea and creatinine decreased earlier and much more rapidly to normal than was to be expected from the natural history of the disease, indicating the prompt and extensive increase of glomerular filtration rate. Polyuria seemed less pronounced and also shortened as compared with the ordinary course of that form of sudden renal insufficiency. Obviously, the well-known diuretic response in the normal individual to high doses of thyroid hormones in not a factor in the induction of diuresis in acute renal failure. The tendency with L-thyroxine treatment to dilate the preglomerular arterial vessel is considered a consequence of the stimulation of sodium reabsorption in the upper nephron. High values of RPF and GFR, regularly observed in hyperthyroidism or after L-thyroxine administration, do not depend on any augmentation of cardiac output or on arterial hypertension, since such symptoms were missed in our patients and, in our view, such an interpretation is excluded by the very existence of the so-called autoregulation of the kidney which leaves RPF (and therefore GFR) independent of systemic blood pressure. The same intrarenal feed-back mechanism, normally adapting the glomerular blood supply to the resorptive capacity of the proximal-tubular epithelium (mediation via the juxta-glomerular apparatus), is responsible for the GFR- and RPF-raising effect of exogenous L-thyroxine in the intact kidney as well as in acute renal failure: both sodium reabsorption and sodium filtration are accelerated.--The special conditions under which L-thyroxine interferes with the pathogenetic process of acute renal failure, the latter being characterised by the critical insufficiency of tubular sodium reabsorption and therefore by

    Screening colonoscopy with polipectomy reduces colonorectal cancer incidence and mortality. An adequate bowel cleansing is one of the keys to achieving best results with this technique. Oral sodium phosphate solution (OSP) had a widespread use in the 90s decade. Its efficacy was similar to polyethylene glycol (PEG) solution, but with less cost and convenient administration. Series of patients with acute renal failure due to OSP use have been reported. However, large cohorts of patients found no difference in the incidence of renal damage between these two solutions. From 2006 to 2009 we identified twelve cases of phosphate nephropathy after colonoscopy prepared with OSP. All patients were followed up to six months. All patients had received just a single dose. We analyzed 12 cases with phosphate nephropathy; three patients debuted with AKI and nine patients had chronic renal injury. Four cases were confirmed with renal biopsy. One patient with AKI needed hemodialysis at diagnosis without subsequent recovery. Two patients (both with chronic damage) fully recovered their previous renal function. The remaining patients (nine) had an average loss of estimated glomerular filtration rate of 24ml/min/1.73m(2). The use of OSP can lead to both acute and chronic renal damage. However, chronic injury was the most common pattern. Both forms of presentation imply a significant and irreversible loss of renal function. Further studies analyzing renal damage secondary to bowel cleaning should consider these two different patterns of injury. Copyright © 2016 Sociedad Española de Nefrología.

    Full Text Available El soporte nutricional en los pacientes críticos que presentan insuficiencia renal aguda ha sido motivo de cambio en los últimos años. Ello es debido al empleo cada vez más frecuente y precoz de las técnicas de depuración extrarenal. Las modificaciones en la pauta de soporte nutricional y metabólico destinadas a evitar la progresión del fracaso renal, recomendadas clásicamente, no tendrían indicación en estas situaciones salvo en los casos no tratados con alguna de las técnicas depurativas. El aporte proteico, por lo tanto, deberá ser adecuado a la situación clínica, no recomendándose ya el empleo de las formulaciones de aminoácidos compuestas exclusivamente por aminoácidos esenciales. La administración de glucosa no sería diferente a la recomendada en otras situaciones. La infusión de lípidos tendría un límite máximo de 1 gr/Kg/día. El empleo de dietas estándar, por tanto, no plantea problemas si los pacientes están siendo tratados con técnicas de depuración. No obstante, la relación entre el flujo de substratos a través de las membranas de diálisis y su efecto sobre la demanda de nutrientes está aún sin establecer de manera clara. Es probable que se requiera un incremento del aporte de nutrientes con el fin de contrarrestar la pérdida obligada por las técnicas de depuración. A la inversa, queda también por estudiar el papel de dichas técnicas como vía adecuada para el soporte nutricional en los pacientes críticos.Nutritional support in critically ill patients that present with acute renal failure has been a matter of change in recent years.

    In the management of patients with congestive heart failure (CHF), it is often desirable to have precise knowledge of overall renal function, including the effective renal plasma flow (ERPF). It has long been recognized that ERPF is diminished in CHF. Since glomerular filtration rate is often decreased to a much lesser extent, other noninvasive procedures such as the measurement of creatinine clearances may not be entirely suitable. ERPF determination by the single plasma sampling (SPS) method affords a rapid, simple, noninvasive, and economical technique that is quite accurate and reproducible. A SPS method has been well-tested in patients following renal transplantation plus a wide variety of nephrological disorders. We have been concerned whether the SPS method would be valid in volume expanded patients. In 28 determinations of ERPF in patients with CHF, and in five patients who did not have CHF, we have found the SPS estimation of ERPF to yield results that are not clinically significantly different from those obtained by the detailed compartmental analysis method. The volumes of /sup 131/I-orthoiodohippurate (OIH) distribution were found to be somewhat higher in CHF than in controls, but fractional rate constants were proportionately lower so that intercompartmental flow rates and OIH concentrations were not different from controls. Therefore, the SPS estimation of ERPF is valid in patients with CHF and may be useful in monitoring the renal effects of various hemodynamic and pharmacological interventions.

Thirty patients with a median glomerular filtration rate (GFR) of 25 ml/(min.1.73 m2) (range 10-43) were randomized to physical training...... the rate of progression judged by the slope of GFR versus time plot was equal in the two groups. Hence, the beneficial effect of exercise training, earlier observed in rat studies, could not be reproduced in our patients. Physical exercise had no untoward effect on progression of renal disease....... (30 min of bicycling daily or an equal amount of other physical activities) or to maintenance of the usual lifestyle. The median maximal work capacity increased significantly in the exercise group and remained unchanged in the control group during a median observation time of 20 months whereas...

    Exogenous arginine slows the progression of chronic renal failure (CRF) in remnant rats through a nitric oxide (NO)-dependent mechanism. We tested whether the inhibition of arginase could induce similar results through the increased availability of endogenous arginine. Three groups of remnant rats were studied for 8 wk: 1) untreated rats (REM); 2) remnant rats treated with 1% l-arginine (ARG); and 3) remnant rats administered a Mn(2+)-free diet to inhibit arginase (MNF). Normal rats (NOR) were used as controls. Liver arginase activity was depressed in MNF rats (-35% vs. REM, P renal hemodynamics. Despite the better GFR, proteinuria was decreased in both ARG and MNF rats (-42%, P renal level, arginase activity was only slightly depressed in MNF rats (-18% vs. REM), but intrarenal concentrations of arginine were lower in this latter group (P factors are involved in these modifications.

    Patients with chronic renal failure are characterized by a tonic elevation of sympathetic tone. This factor largely contributes to their increased cardiovascular risk. The increased sympathetic drive is caused by activiation of renal afferent fibers in the diseased kidneys. Therapeutic options for hypertensive patients with chronic renal failure with respect to their sympathetic overactivity are inhibitors of the renin-angiotensin-system and central sympatholytic drugs. The role of catheter-based renal denervation in these patients is currently under investigation.

    Renal dysfunction (RD) is associated with increased mortality in heart failure (HF). The aim of this study was to identify whether worsened or improved renal function during mid-term follow-up is associated with worsened outcomes in patients with chronic HF. A total of 892 participants from a multicenter cohort study of chronic HF were followed over 3.1 ± 1.9 years of enrollment. Worsened and improved renal functions were tested with multivariate models as independent predictors of HF hospitalization and mortality. Although 12% of subjects experienced a ≥25% decrease in estimated glomerular filtration rate (eGFR), 17% experienced a ≥25% increase in eGFR, and there was stability of kidney function observed in the cohort as a whole. The quartile with the worst RD at any point in time had increased risk of HF hospitalization and mortality. Worsened eGFR was associated with HF outcomes in the unadjusted (hazard ratio = 1.71, 95% confidence interval 1.04 to 2.81, p = 0.035), but not the adjusted analysis. Improvement in eGFR was not associated with outcome (p = 0.453). In chronic HF, the severity of RD predicts risk of poor outcome better than changes in renal function during mid-term follow-up. This suggests that in patients with appropriately treated chronic HF, worsening renal function in itself does not yield useful prognostic information and may not reflect poor outcome.

  5. NSAID nephrotoxicity revisited: acute renal failure due to parenteral ketorolac.

    Perazella, M A; Buller, G K

    1993-12-01

    The success of ketorolac as a nonnarcotic analgesic is likely to propagate its widespread use to control moderate to severe postoperative pain. Indeed, of the patients treated with ketorolac and described in the medical literature, nearly 90% had had a major surgical procedure. Since any such procedure may be associated with significant third-spacing of the fluid and result in renal hypoperfusion, care must be taken in administering ketorolac. Close attention to urine output and parameters of renal function must be maintained. Moreover, postoperative ketorolac therapy should be avoided in patients who have conditions that predispose to NSAID nephrotoxicity (as in our Case 1). Likewise, in nonsurgical patients the same degree of caution should be used with ketorolac as with any oral NSAID. Finally, since ketorolac is excreted almost entirely by the kidney, either elderly patients or patients with underlying renal insufficiency must have an adjustment of the dosing interval, or this medication should be avoided in such patients altogether.

    2016-07-01

    Acute renal failure (ARF) in adults in the intensive care unit (ICU) often evolves in a context of multiple organ failure, which explains the high mortality rate and increase treatment needs. Among, two modalities of renal replacement therapy, peritoneal dialysis (PD) was the first modality used for the treatment of ARF in the 1950s. Today, while PD is generalized for chronic renal failure treatment, its use in the ICU is limited, particularly, due to the advent of new hemodialysis techniques and the development of continuous replacement therapy. Recently, a renewed interest in the use of PD in patients with ARF has manifested in several emerging countries (Brazil, Vietnam). A systematic review in 2013 showed a similar mortality in ARF patients having PD (58%) and those treated by hemodialysis or hemodiafiltration/hemofiltration (56.1%). In the International society of peritoneal dialysis (ISPD)'s guideline (2013), PD may be used in adult ARF as the other blood extracorporeal epuration technics (recommendation with grade 1B). PD is the preferred method in cardiorenal syndromes, in frailty patients with hemodynamic instability and those lacking vascular access; finally PD is also an option in elderly and patients with bleeding tendency. In industrial countries, high volume automated PD with a flexible catheter (usually Tenckhoff) is advocated. Copyright © 2016 Association Société de néphrologie. Published by Elsevier SAS.

  8. Are calcium oxalate crystals involved in the mechanism of acute renal failure in ethylene glycol poisoning?

    Science.gov (United States)

    McMartin, Kenneth

    2009-11-01

    Ethylene glycol (EG) poisoning often results in acute renal failure, particularly if treatment with fomepizole or ethanol is delayed because of late presentation or diagnosis. The mechanism has not been established but is thought to result from the production of a toxic metabolite. A literature review utilizing PubMed identified papers dealing with renal toxicity and EG or oxalate. The list of papers was culled to those relevant to the mechanism and treatment of the renal toxicity associated with either compound. ROLE OF METABOLITES: Although the "aldehyde" metabolites of EG, glycolaldehyde, and glyoxalate, have been suggested as the metabolites responsible, recent studies have shown definitively that the accumulation of calcium oxalate monohydrate (COM) crystals in kidney tissue produces renal tubular necrosis that leads to kidney failure. In vivo studies in EG-dosed rats have correlated the severity of renal damage with the total accumulation of COM crystals in kidney tissue. Studies in cultured kidney cells, including human proximal tubule (HPT) cells, have demonstrated that only COM crystals, not the oxalate ion, glycolaldehyde, or glyoxylate, produce a necrotic cell death at toxicologically relevant concentrations. COM CRYSTAL ACCUMULATION: In EG poisoning, COM crystals accumulate to high concentrations in the kidney through a process involving adherence to tubular cell membranes, followed by internalization of the crystals. MECHANISM OF TOXICITY: COM crystals have been shown to alter membrane structure and function, to increase reactive oxygen species and to produce mitochondrial dysfunction. These processes are likely to be involved in the mechanism of cell death. Accumulation of COM crystals in the kidney is responsible for producing the renal toxicity associated with EG poisoning. The development of a pharmacological approach to reduce COM crystal adherence to tubular cells and its cellular interactions would be valuable as this would decrease the renal

    Life threatening conditions characterized by renal ischemia/reperfusion (RIR) such as kidney transplantation, partial nephrectomy, renal artery angioplasty, cardiopulmonary bypass and aortic bypass surgery, continue to be among the most frequent causes of acute renal failure. The current study investigated the possible protective effects of tadalafil alone and in combination with diltiazem in experimentally-induced renal ischemia/reperfusion injury in rats. Possible underlying mechanisms were also investigated such as oxidative stress and inflammation. Rats were divided into sham-operated and I/R-operated groups. Anesthetized rats (urethane 1.3g/kg) were subjected to bilateral ischemia for 30min by occlusion of renal pedicles, then reperfused for 6h. Rats in the vehicle I/R group showed a significant (p˂0.05) increase in kidney malondialdehyde (MDA) content; myeloperoxidase (MPO) activity; TNF-α and IL-1β contents. In addition significant (p˂0.05) increase in intercellular adhesion molecule-1(ICAM-1) content, BUN and creatinine levels, along with significant decrease in kidney superoxide dismutase (SOD) activity. In addition, marked diffuse histopathological damage and severe cytoplasmic staining of caspase-3 were detected. Pretreatment with combination of tadalafil (5mg/kg bdwt) and diltiazem (5mg/kg bdwt) resulted in reversal of the increased biochemical parameters investigated. Also, histopathological examination revealed partial return to normal cellular architecture. In conclusion, pretreatment with tadalafil and diltiazem combination protected against RIR injury.

    Heart and kidney interactions are fascinating, in the sense that failure of the one organ strongly affects the function of the other. In this review paper, we analyze how principal driving forces for glomerular filtration and renal blood flow are changed in heart failure. Moreover, renal autoregulation and modulation of neurohumoral factors, which can both have repercussions on renal function, are analyzed. Two paradigms seem to apply. One is that the renin-angiotensin system (RAS), the sympathetic nervous system (SNS), and extracellular volume control are the three main determinants of renal function in heart failure. The other is that the classical paradigm to analyze renal dysfunction that is widely applied in nephrology also applies to the pathophysiology of heart failure: pre-renal, intra-renal, and post-renal alterations together determine glomerular filtration. At variance with the classical paradigm is that the most important post-renal factor in heart failure seems renal venous hypertension that, by increasing renal tubular pressure, decreases GFR. When different pharmacological strategies to inhibit the RAS and SNS and to assist renal volume control are considered, there is a painful lack in knowledge about how widely applied drugs affect primary driving forces for ultrafiltration, renal autoregulation, and neurohumoral control. We call for more clinical physiological studies.

    Interventional catheterization procedures may be needed for patients with severe renal failure who are dependent on dialysis. To avoid the risk of fluid overload and electrolyte derangement during complex procedures in this oliguric/anuric patient population, we performed intra-procedural dialysis, either continuous renal replacement therapy (CRRT) or continous cycling peritoneal dialysis (CCPD). We performed a retrospective review of a cohort of pediatric patients, ages 0-18 years, with dialysis-dependent renal failure who received CRRT or CCPD during catheterization procedures from January 2013 to March 2016. Eight patients underwent a total of nine interventional catheterization procedures while receiving intra-procedural dialysis. Median age was 4.5 years (range 8 months to 17 years) and weight, 11.6 kg (11.2-62.6 kg). Six patients had end-stage renal disease (ESRD) and two patients had acute kidney injury (AKI), one due to hepatorenal syndrome and one due to multifactorial causes associated with congenital heart disease. The most common reason for catheterization was occlusive venous thrombosis requiring recanalization. CRRT was used during five cases and CCPD during four cases. Median procedure time was 337 min (95-651 min) and median contrast dose 4.2 mL kg(-1) (1.2-8.2 mL kg(-1) ). Euvolemia was maintained based on pre- and post-catheterizations weights, and no significant electrolyte abnormalities occurred based on lab monitoring during and post-procedure. Intra-procedural dialysis using CRRT or CCPD enables even small pediatric patients with severe renal failure to undergo long and complex interventional catheterizations by reducing the risk of fluid overload and electrolyte abnormalities. Collaboration between nephrology, cardiology, and dialysis teams is necessary for successful management of this challenging patient population. © 2017 Wiley Periodicals, Inc.

    Compressive myopathy syndrome (SCM) is a syndrome characterized by the lesion of skeletal muscle resulting in subsequent release of intracellular contents (myoglobin, creatine phosphokinase, potassium, etc.) into the circulatory system, which can cause potentially lethal complications. There are numerous causes that can lead to SCM resulting to acute rhabdomyolysis, and many patients present with multiple causes. The most common potentially lethal complication is acute renal failure. The occurrence of acute rhabdomyolysis should be considered as a possibility in any patient who can remain stationary for long periods, or is in a coma, or is intoxicated in any form. We report the rare case of a 26-year-old patient who developed SCM caused by ischemia reperfusion, with subsequent acute rhabdomyolysis and acute renal failure after prolonged compression of the right upper extremity.

    Full Text Available Aim. The case of successful surgical treatment of anterolateral papillary muscle rupture due to acute myocardial infarction with cardiogenic shock, pulmonary edema and acute renal failure. Case report. A 62-year old male from Belgrade with chest pain, hypotension and a new heart murmur refused hospitalization at the Military Medical Academy. On the third day of his illness he was readmitted to MMA as an emergency due to hemoptysis. Examination revealed mitral valve anterolateral papillary muscle rupture. The patient, with signs of cardiogenic shock and acute renal failure, was immediately operated on. The surgery was performed using extracorporeal circulation. An artificial mitral valve was implanted, and myocardial revascularization accomplished with one venous graft of the left anterior descending artery. On the second postoperative day, hemodialysis was carried out due to acute renal failure. On the 28th postoperative day, the patient was discharged from the hospital being hemodynamically stable with normal renal function and balanced anticoagulation. The case is interesting in terms of unrecognized papillary muscle rupture that led to the development of cardiogenic shock, hemoptysis and acute renal failure. Conclusion. Papillary muscle rupture is a fatal complication of acute myocardial infarction. Early recognition and urgent surgical intervention were lifesaving in the case of complete papillary muscle rupture. Surgical treatment, regardless of high risk, is the procedure of choice.

    Chronic renal failure is often associated with multiple organ co-morbidities, including thyroid dysfunction. This has been associated with poorer prognosis, particularly in patients with end-stage renal disease. This study aimed to examine the relationship between renal failure and thyroid dysfunction in an outpatient setting at the King Abdulaziz University Hospital, Saudi Arabia, from January 2011 to June 2012. Demographic and biochemical data were extracted from medical records. Differences in the levels of thyroid hormones and lipids between the four renal function groups were analyzed using the chi-square test for categorical variables and Kruskal- Wallis test for binomial variables. A total of 486 patients were included in the study population, of whom approximately half were female, and the median (range) age was 61 (17-90) years. According to creatinine measurements, renal function was normal in 48 participants, 290 had mild renal failure, 122 had moderate renal failure and 26 had severe renal failure. No significant relationships were observed between renal failure and cardiac or pulmonary dysfunction. Free triiodothyronine (FT3) levels were significantly reduced (P = 0.005) and both free thyroxin (FT4; P = 0.034) and parathyroid hormone (PTH; P = 0.028) significantly increased with increasing severity of renal failure. Patients with moderate to severe renal failure displayed reduced hemoglobin levels and were significantly more likely to be anemic (P renal dysfunction. To conclude, it was observed that renal dysfunction is associated with notable changes to other organ systems, including the thyroid. Further studies may investigate the association of multiple organ co-morbidities with prognosis in patients with chronic renal failure.

    Full Text Available Hepatitis C virus (HCV infection has come to the top of virus-induced liver diseases in many parts of the world. In Iran, it seems that HCV prevalence in general population is less than one percent, which is much lower than in most of the regional countries(1. However, the infection is emerging in Iran mostly due to problem of intravenous drug abuse and needle-sharing in the country (2, 3. The patients receiving maintenance transfusion such as chronic renal failure (CRF patients and the patients with thalassemia major are the other population who are at the high risk of HCV acquisition although compulsory blood screening has been able to remarkably decrease the HCV incidence in these patients (4. The prevalence of HCV infection among CRF patients on hemodialysis in Tehran, the capital of Iran, was around 13 percent in 2002 (5. There is no valid data regarding HCV incidence rate among CRF patients in country. However, according to the most recent official report of Management of Special Diseases and Transplantation Center (MSDT, the prevalence of HCV infection among patients on hemodialysis in the whole country has decreased from 14.4% in 1999 to 4.5% in 2005. Various reasons might be responsible for this reduction such as blood screening; developing technology of alternative modalities instead of transfusion in Iran like producing domestic Erythropoietin which has been resulted in decreasing transfusion; early transplantation; and training health staffs. On the other hand, the other reason such as mortality ofHCV infected CRF patients should not be neglected. Although there is no data in this regard in Iran, a meta-analysis, demonstrated that HCV infected patients on dialysis have an increased risk of mortality compared to HCV negative cases (6. Therefore, with the lack of data defining incidence rate in Iran, the reduction of HCV prevalence in the country should not overlook the necessity of designing a comprehensive strategy to control HCV

    Full Text Available Introduction. Hemodialysis and transplantation are performed not only to replace renal function, but also to improve patients' quality of life. The aim of our investigation was to compare the quality of life in patients with chronic renal failure (CRF before and after the introduction of active therapy. Material and methods. We tested 76 patients (pts: 20 pts on conservative therapy (CT, 21 pts on chronic hemodialysis and 35 pts with renal transplantation. A questionnaire (combining two questionnaires was used to investigate the physical, emotional and social aspects of health. Results. In regard to physical health of transplantation patients (TP it was established that work capacity and activities were less damaged, whereas physical activity was highest in pts on CT. Social activity was limited in a higher percentage in TP (40% than in hemodialysis patients (HD (19%, while family relationships were most damaged in pts on HD (28.57%. Discomforts were most common in pts on HD. The highest percentage of pts estimated their health status as good or average, but their health status improved after transplantation in 82.86% that is in 57.14% after HD. It was similar with the quality of life: 28.57% of kidney transplant patients rated their quality of life as very good, and 54.28% rated it as good; 38.09% of HD patients rated their quality of life as very good, whereas only 5% of CT patients rated it as very good, and 20% as good. .

  19. Oral disorders in patients with chronic renal failure. Narrative review

    Full Text Available Chronic renal failure (CRF is one of the best known renal diseases. It is characterized by a deterioration in the overall renal function and is associated with other conditions such as hypertension, diabetes mellitus, uropathy, chronic glomerulonephritis and autoimmune diseases. Patients with CRF show alterations of the masticatory system that are specific to the disease and other type of disorders as a result of treatment. Oral health in dialysis and transplant patients tends to be poor, which makes them more likely to develop pathological conditions in the oral cavity, potentially increasing morbidity, mortality and affecting the quality of life of patients. Among the lesions we can find dysgeusia, periodontitis, candidiasis, gingival bleeding, petechiae, and joint alterations. Gingivitis and xerostomia associated to long-term use medications can cause oral lesions. Children with CRF show two oral conditions of interest: high incidence of dental anomalies and low caries activity. In patients receiving a kidney transplant, previous dental treatment is critical because the immune status of the patient will be affected not only by the toxemia, but by the immunosuppressive drugs used to prevent transplant rejection. Therefore, the dentist plays an important role in training parents and/or guardians, doctors and paramedics on the treatment of oral lesions in these patients

    Full Text Available Management of patients with renal failure remains a major problem in poor-resource nations. Cutaneous manifestations in this group of patients are varied and remain helpful in differentiating acute from chronic renal failure (CRF. We studied the prevalence and pattern of skin disorders in patients with CRF at The University College Hospital, Ibadan, Nigeria, during the period between May 2006 and February 2007. Relevant information was collected with the aid of a questionnaire. The patients were then examined for skin disorders. One hundred and twenty patients who met the inclusion criteria were recruited into the study. The mean age of the CRF patients was 43.12 ± 15.38 years, while that of the control subjects was 43.13 ± 15.38 years. Seventy-six of the 120 patients (63.3% were on chronic hemodialysis while 44 (36.5% were on conservative management. A total of 107 patients (89.1% had at least one skin problem. The skin disorders seen include xerosis in 72 (60%, pruritus in 32 (26.7%, hyper-pigmentation, icthyosis and pityriasis versicolor in nine patients each (7.5%, either singly or in combination. Pallor of the skin was seen in three of the patients (2.5%, while uremic frost was seen in one (0.8%. Nail changes were seen in 48 patients (40%. We conclude that xerosis, pruritus, pigmentary and nail changes were the most common skin disorders in patients with CRF in our environment.

    Full Text Available Cardiovascular disease is highly prevalent in patients with chronic renal failure (CRF. However, data on the impact of CRF on the cerebral circulatory system are scarce—despite the fact that stroke is the third most common cause of cardiovascular death in people with CRF. In the present study, we examined the impact of CRF on behavior (anxiety, recognition and ischemic stroke severity in a well-defined murine model of CRF. We did not observe any significant increases between CRF mice and non-CRF mice in terms of anxiety. In contrast, CRF mice showed lower levels of anxiety in some tests. Recognition was not impaired (vs. controls after 6 weeks of CRF but was impaired after 10 weeks of CRF. Chronic renal failure enhances the severity of ischemic stroke, as evaluated by the infarct volume size in CRF mice after 34 weeks of CRF. Furthermore, neurological test results in non-CRF mice tended to improve in the days following ischemic stroke, whereas the results in CRF mice tended to worsen. In conclusion, we showed that a murine model of CRF is suitable for evaluating uremic toxicity and the associated neurological disorders. Our data confirm the role of uremic toxicity in the genesis of neurological abnormalities (other than anxiety.

    We report the case of a 45-year-old chronic smoker who presented with acute paraplegia occurring during coitus and subsequently developed acute renal failure (ARF) requiring dialysis. He had absent peripheral pulses in the lower limbs with evidence of acute ischemia. Doppler study showed dissecting aneurysm of thoracic aorta, thrombotic occlusion of the distal aorta from L1 level up to bifurcation and occlusion of the right renal artery by a thrombus that was confirmed by magnetic resonance imaging of the spine. He was not subjected to any vascular intervention as his lower limbs were not salvageable due to delay in the diagnosis. Post-coital aortic dissection and aortic dissection presenting with acute paraplegia and ARF are very rare. This is probably the first case report with post-coital acute aortic dissection presenting with paraplegia and ARF. This case emphasizes the importance of a careful examination of peripheral pulses in patients presenting with ARF and paraplegia.

    Impaired renal function is associated with an increased risk for cardiovascular events and death, but the pathophysiology is poorly defined. The hypothesis that coronary blood flow regulation and distribution of ventricular blood flow could be compromised during acute renal failure (ARF) was tested. In two separate groups (n = 14 each) of dogs with ARF, (1) coronary autoregulation (pressure-flow relations), vascular reserve (reactive hyperemia), and myocardial blood flow distribution (microspheres) and (2) coronary vessel responses to intracoronary infusion of select endothelium-dependent and -independent vasodilators were evaluated. In addition, coronary pressure-flow relations and vascular reserve after inhibition of nitric oxide and prostaglandin release were evaluated. Under resting conditions, myocardial oxygen consumption increased in dogs with ARF compared with no renal failure (NRF; 11.8 +/- 9.2 versus 5.0 +/- 1.5 ml O(2)/min per 100 g; P = 0.01), and the autoregulatory break point of the coronary pressure-flow relation was shifted to higher diastolic coronary pressures (60 +/- 17 versus 52 +/- 8 mmHg in NRF; P = 0.003); the latter was shifted further rightward after inhibition of both nitric oxide and prostaglandin release. The endocardial/epicardial blood flow ratio was comparable for both groups, suggesting preserved ventricular distribution of blood flow. In dogs with ARF, coronary vascular conductance also was reduced (P = 0.001 versus NRF), but coronary zero-flow pressure was unchanged. Vessel reactivity to each endothelium-dependent/independent compound also was blunted significantly. In conclusion, under resting conditions, coronary vascular tone, reserve, and vessel reactivity are markedly diminished with ARF, suggesting impaired vascular function. Consequently, during ARF, small increases in myocardial oxygen demand would induce subendocardial ischemia as a result of a limited capacity to increase oxygen supply and thereby contribute to higher

    Lithium users are offered routine renal monitoring but few studies have quantified the risk to renal health. The aim of this study was to assess the association between use of lithium carbonate and incidence of renal failure in patients with bipolar disorder. This was a retrospective cohort study using the General Practice Research Database (GPRD) and a nested validation study of lithium exposure and renal failure. A cohort of 6360 participants aged over 18 years had a first recorded diagnosis of bipolar disorder between January 1, 1990 and December 31, 2007. Data were examined from electronic primary care records from 418 general practices across the UK. The primary outcome was the hazard ratio for renal failure in participants exposed to lithium carbonate as compared with non-users of lithium, adjusting for age, gender, co-morbidities, and poly-pharmacy. Ever use of lithium was associated with a hazard ratio for renal failure of 2.5 (95% confidence interval 1.6 to 4.0) adjusted for known renal risk factors. Absolute risk was age dependent, with patients of 50 years or older at particular risk of renal failure: Number Needed to Harm (NNH) was 44 (21 to 150). Lithium is associated with an increased risk of renal failure, particularly among the older age group. The absolute risk of renal failure associated with lithium use remains small.

    Acute antibody mediated rejection (AMR) is one of the most important complications after kidney transplantation. Renal graft biopsy is safe and reliable without adverse effects on the patients and transplanted kidneys, which was of great instructive significance in diagnosis and treatment of renal allograft dysfunction after renal transplantation. This paper reported a case series of 106 patients underwent renal allograft biopsies. All biopsies were evaluated according to the Banff 2007 schema. 52 examples were obtained within 1 month after transplantation, and there were another 20 examples in one to two months and other 34 examples in two to three months. Appropriate therapy was applied and clinical outcomes were observed. All patients received renal biopsies and anti-inflammatory and hemostasis treatment without complications. There were 2 cases of hyperacute rejection, and 15 cases of acute AMR. All Paraffin-embedded samples were stained by HE, periodic acid-Schiff (PAS), Masson, and immunohistochemistry (C4d, cd20, cd45RO, SV40). All samples were found C4d immunohistochemical staining positive. Patients with acute AMR were managed by steroid intravenous pulse therapy, Rabbit anti-thymocyte globulin intravenous pulse therapy, anti CD20 monoclonal antibody intravenous therapy and so on. Two cases of hyperacute rejection had renal failure, and received kidney excision; 12 cases in 15 cases of AMR recovered, another 2 cases did not recover with high-level creatine, and other 2 cases of renal allograft received excision.

    Full Text Available Abstract Background Severe renal manifestation of systemic lupus erythematosus (SLE is not uncommon and is associated with an indeterminate prognosis. Complete remission can be obtained, however, at least in the young when chronic lesions are absent and adequate anti-inflammatory therapy is immediately initiated. Case presentation We report the unusual case of a 12-year-old girl who presented with severe oliguric renal failure, macrohematuria and skin rash. Renal biopsy revealed the diagnosis of severe diffuse proliferative glomerulonephritis (GN with cellular crescents in 15 out of 18 glomeruli and full-house pattern in immunofluorescence indicating lupus nephritis IVB according to WHO, IV-G(A according to ISN/RPS classification. The serological parameters confirmed the diagnosis of SLE and the patient was immediately treated with methylprednisolone, cyclophosphamide and immunoadsorption. Initially, despite rapid amelioration of her general condition, no substantial improvement of renal function could be achieved and the patient needed hemodialysis treatment for 12 weeks. Unexpectedly, in the further follow-up at first diuresis increased and thereafter also creatinine levels substantially declined so that hemodialysis could be discontinued. Today, 6 years after the initial presentation, the patient has normal renal function and a SLEDAI score of 0 under a continuous immunosuppressive therapy with Mycophenolate mofetil (MMF and low dose steroid. Conclusion Despite the severity of the initial renal injury and the unfavourable renal prognosis the kidney apparently has a tremendous capacity to recover in young patients when the damage is acute and adequate anti-inflammatory therapy is initiated without delay.

    Leptospirosis is an infectious disease caused by pathogenic leptospires and is characterized by a broad spectrum of clinical manifestations, varying from inappearent infection to fulminant, fetal disease. Eighty-five to 90% of leptospirosis infections are self-limiting. However, 5-10% of infection by L. interrogans can cause renal tubular damage, microvascular injury, acute renal failure (ARF), and interstitial nephritis. We studied 36 patients with leptospirosis. Twenty-seven (65%) cases of 36 patients had ARF. Fourteen (51%) had nonoliguric ARF. In thirteen (48%) oliguria appeared on the third or fourth days of hospitalization. Serum BUN, creatinine, serum bilirubine, ALT, AST, potassium and thrombocytopenia levels were higher in oliguric than nonoliguric patients (p 0.05). Thirteen patients (48%) needed in renal replacement therapy (RRT). 8 of them were treated by hemodialysis (HD) alone and 5 patients by HD in combination with hemoperfusion. Twenty-five patients (92%) recovered completely after 3-5 weeks. Two patients (7.4%) who had severe hepatorenal and hemorrhagic syndromes, died. We concluded that till now leptospirosis is actual problem for nephrologist in the developing countries because of very high percentage of renal disease, with good prognosis in patients without multiorgan failure and early treatment.

    Renal disease is a relatively common complication in patients infected with the human immunodeficiency virus (HIV). A collapsing form of focal glomerulosclerosis has been considered as the primary form of HIV nephropathy. HIV infection is also associated with an increasing number of different forms of renal disease. Acute renal failure (ARF) syndromes are frequently noted during the course of HIV infection. The most common include the following: acute and often reversible renal failure resulting from infection, hypotension, and administration of nephrotoxins used to treat opportunistic infections, and the use of highly active anti-retroviral therapy. ARF has been reported in up to 20% of hospitalized HIV infected patients compared to 3 to 5% of non-HIV infected patients. Primary HIV infection is usually symptomatic, and infected patients can present with a variety of symptoms. Although ARF syndromes are frequently noted during the course of infection, it is an uncommon presentation of primary HIV infection. We describe a 42-year-old man who presented at our hospital with acute self-limited rhabdomyolysis and who was found to have primary HIV infection. Our case and other reports suggest that a diagnosis of primary HIV infection needs to be considered in patients who present with acute rhabdomyolysis.

    Full Text Available BACKGROUND: Patients with CRF often have signs & symptoms suggestive of thyroid dysfunctions. Prevalence of hypothyroidism in patients with terminal renal failure is 5%, in comparison with that in hospitalized patients with normal renal function . CKD is associated with higher prevalence of hypothyroidism, both overt and subclinical, but not with hyperthyroidism. In fact, the prevalence of primary hypothyroidism is mainly in the subclinical form, which increases as GFR decreases. OBJECTIVES: To estimate thyroid hormone levels i. e. T 3 , T 4 & TSH in CRF. To estimate Serum urea & creatinine for selection and categorizing the study subjects in to different grades of CRF. To study the thyroid hormone levels and thyroid abnormalities as the severity of CRF increases. MATERIALS AND METHO DS: In this study 30 male patients of aged between 40 - 70yrs . with serum creatinine >5.5mg/dl & urea >55mg/dl and dipstick test positive for protein with symptoms of chronic renal failure are taken as cases. Age and sex matched normal healthy indi vi duals ar e taken as controls. Serum Urea Estimated by DAM Method, serum creatinine is estimated by Jaffe’s method and Serum levels of T 3 , T 4 & TSH were analysed by using CLIA method. Results: T 3 , T 4 decreases and TSH increases significantly in cases compare to the controls as the severity of dieses increases . In our study 10% of patients of CRF are hypothyroid and all these hypothyroid patients belongs to serum creatinine above 6 mg/dl category. CONC LUSION: Mean of T 3 , T 4 decreases TSH increases significantly in cases compare to controls as the severity of CRF increases. The risk of hypothyroidism in chronic renal failure is very high if serum creatinine level are above 6 mg/dl.

    Acute kidney injury (AKI) is an important clinical issue, especially in the setting of critical care. It has been shown in multiple studies to be a key independent risk factor for mortality, even after adjustment for demographics and severity of illness. There is wide agreement that a generally applicable classification system is required for AKI which helps to standardize estimation of severity of renal disfunction and to predict outcome associated with this condition. That's how RIFLE (Risk-Injury-Failure-Loss-End-stage renal disease), and AKIN (Acute Kidney Injury Network) classifications for AKI were found in 2004 and 2007, respectively. In the clinical setting of heart failure, a positive fluid balance (often expressed in the literature as weight gain) is used by disease management programs as a marker of heart failure decompensation. Oliguria is defined as urine output less than 0,3 ml/kg/h for at least 24 h. Since any delay in treatment can lead to a dangerous progression of the AKI, early recognition of oliguria appears to be crucial. Critically ill patients with oliguric AKI are at increased risk for fluid imbalance due to widespread systemic inflammation, reduced plasma oncotic pressure and increased capillary leak. These patients are particulary at risk of fluid overload and therefore restrictive strategy of fluid administration should be used. Objective, rapid and accurate volume assessment is important in undiagnosed patients presenting with critical illness, as errors may result in interventions with fatal outcomes. The historical tools such as physical exam, and chest radiography suffer from significant limitations. As gold standard, radioisolopic measurement of volume is impractical in the acute care enviroment. Newer technologies offer the promise of both rapid and accurate bedside estimation of volume status with the potential to improve clinical outcomes. Blood assessment with bioimpendance vector analysis, and bedside ultrasound seem to be

    Full Text Available Objectives To evaluate the result of treatment of acute renal failure (ARF in patients after cardiac surgery. Methods The clinical data of 54 cases admitted to the hospital from Jan. 2004 to Jan. 2014 and suffered from ARF after cardiac surgery were retrospectively analyzed. Among 54 cases, there were 35 males and 19 females, aged from one month to 79 years with a median of 52 years. The surgical procedures included coronary artery bypass grafting (CABG, 10 cases, valve surgery (22 cases, combined CABG and valve surgery (4 cases, operation on aorta (14 case, and radical correction of Fallot tetralogy (4 cases. After the operations mentioned above, 50 patients received continuous renal replacement therapy (CRRT, and 4 patients received peritoneal dialysis. Results Nine patients died, the mortality rate was 16.7%. Exploratory hemostasis by thoracotomy was performed in 8 patients, and extubation failure occurred in 4 cases. Of the 9 non-survivors, 6 died from multiple organ failure (MOF, 2 died from cerebral hemorrhage, and one died from acute respiratory failure. Serum creatinine (SCr and blood urea nitrogen (BUN levels declined obviously after CRRT and peritoneal dialysis (P<0.05, and all the patients were shown to have stable hemodynamics in the course of treatment, and no hemorrhage or embolism occurred. Conclusions ARF after cardiac surgery should be detected early and treated in time. CRRT and peritoneal dialysis are safe, convenient and effective procedures, and may decrease the mortality rate in patients with ARF after cardiac surgery. DOI: 10.11855/j.issn.0557-7402.2015.04.13

    Full Text Available The aim of this study was to analyse the demographic variables of chronic non-terminal (CRF and terminal (TRF renal failure patients (pts younger than 19 years treated in Serbia in June 2001. The prevalence of CRF pts was registered as 4,7 per million total population (pmtp or 14,1 per million child population (pmcp while corresponding values for TRF pts were 4,5 pmtp or 13,5 pmcp. The incidence of TRF pts during the period Jan.2000-Jan.2002 was 4,35 pmcp. Boys dominated only among CRF pts (34:14; 60,4% beeing between the ages of 6 and 19 yrs while at the time of diagnosis of HBI, 33,3 % of boys were yanger than 2 yrs.The causes of CRF were: reflux nephropathy 58,3%, congenital kidney disease 16,7%, familial/hereditary 14,6% glomerulonephritis 6,2% and Willms tu 4,1%. Reflux nephropathy was also the most common underlying disease of TRF accounted for 36,9% of total cases while glomerulonephritis was responsible for 23,9 %. Reflux nephropathy was associated with neural tube defect in 53,3% and with congenital lower urinary tract obstruction in 66,7%. The most of CRF (81,25% and TRF pts (95,6% were from Serbia, the others were from Monte Negro and Republic Srpska. The most of CRF (65% and TRF (80% pts were treated in University Children’s Hospital in Belgrade. Of CRF pts 46% had serum sreatinine 100-200 μmol/l, in 11% of pts it was 400-600 μmol/l and 2% of pts were in pre-terminal CRF. One third of CRF pts had proteinuria 150-500 mg/l, and second third had proteinuria greater of 1000 mg/l. Anemia was present in 54% of CRf pts, and arterial hypertension in 56%. Hemodialysis was dominant treatment modality for TRF pts and only 23,9% had functioning transplant. Conclusion: This is the first national study of demographic characteristics of pediatric CRF in Serbia. Since its prevalence is considerably lower than that in Western and North European countries the true prevalence is some what higher. The increasing incidence of pediatric TRF from 2

    Prolongation of the QTc interval, a risk factor for cardiac arrhythmias, has been observed in adult hemodialysis patients; there are few data on the QTc interval in children with chronic renal failure (CRF) and following renal transplantation (Tx). The purpose of our study was to determine the QTc interval in children with CRF and post renal Tx. Twenty children with CRF and 16 children with renal Tx who were followed at the University of California, Davis, underwent prospective EKG monitoring. The mean QTc interval in the CRF and post-Tx cohorts was normal at 407.9 ms and 408.2 ms, respectively. None of the children with CRF had QTc prolongation. Two Tx recipients had QTc prolongation; both had cardiac dilatation on echocardiography (ECHO). There was no correlation between the QTc interval and the creatinine clearance in either group. However, a significant correlation was noted between QTc prolongation and cardiac dilatation on ECHO in the Tx group (P=0.02, Fisher's exact test). In conclusion, QTc prolongation is uncommon in children with CRF and following Tx, in the absence of cardiac dilatation. However, caution is still needed before prescribing medications known to cause QTc prolongation.

    Full Text Available Beyazit ZencirciKahramanmaras, TurkeyBackground: Chronic renal failure is strongly associated with poor pregnancy outcome. Women dependent on hemodialysis before conception rarely achieve a successful live birth.Case presentation: A 31-year-old multiparous Turkish woman was scheduled for cesarean section under spinal anesthesia at 37 weeks and five days’ gestation because of hemorrhage due to secondary placenta previa. Spinal anesthesia with 8 mg of hyperbaric bupivacaine was successfully performed. Invasive blood pressure, central venous pressure, and heart rate were stable during the surgery. The mother returned to regular hemodialysis on the first postoperative day.Conclusion: Pregnancy is uncommon in women with chronic renal failure requiring chronic dialysis. Rates of maternal hypertension, pre-eclampsia, anemia, and infection in the pregnant chronic dialysis patient are high. However, our findings suggest that with careful, close, and effective monitoring preoperatively and intraoperatively, spinal anesthesia can be safely performed for cesarean section in patients undergoing hemodialysis.Keywords: chronic renal failure, pregnancy, spinal anesthesia, hemodialysis, placenta previa

    Full Text Available Experimental and clinical studies analyzing the impact of AVF on cardiovascular and renal parameters, as well as outcomes, in kidney transplant recipients are lacking. On the other hand, it is not known whether AVF ligation after transplantation modifies hemodynamic parameters and kidney function. We report a case of a renal transplant recipient who developed an acute congestive heart failure accompanied by renal failure, which were triggered by femorofemoral AVF angioplasty. Prompt AVF ligation rapidly reversed clinical symptoms and normalized cardiac and renal functions. This paper illustrates the potential deleterious consequences of high-output AVF after kidney transplantation and raises considerations regarding the impact of the fistula on cardiac status and kidney function after kidney transplantation and, consequently, the management AVF after transplantation.

    We present a case of acute hemolytic anemia, renal failure, and Clostridium perfringens bacteremia in a patient with acute myelogenous leukemia. The high fatality of C. perfringens bacteremia requires that clinicians recognize and rapidly treat patients at risk for this infection. Although other hemolytic processes are in the differential diagnosis of these events, the presence of high fever, chills, and rapidly positive blood cultures may help narrow the diagnosis. Most cases of C. perfringens bacteremia have a concomitant coinfection, which makes broad spectrum empiric therapy essential. There is a high mortality rate of C. perfringens infections associated with leukemia.

    The illegal enrichment of anabolic androgenic steroids in over-the-counter dietary supplements is well documented, but the health consequences have not been widely recognized. Three recent reports document cholestatic jaundice and nephropathy due to these compounds. We present 3 additional cases of anabolic androgenic steroid-enriched dietary supplement-induced hepatotoxicity and 1 case of renal failure, and we review the literature and the relevant features of this growing health concern. Recognition of this entity could obviate the need for invasive diagnostic testing and hospitalization and facilitate diagnosis and appropriate counseling.

    The aim of this study was to investigate the risk of acute renal failure (ARF), the need for renal replacement therapy, and the outcome of children with a solitary functioning kidney undergoing open heart surgery. The study was performed retrospectively on all children diagnosed with solitary functioning kidney and who required open heart surgery between January 2003 and January 2007. Demographic, perioperative renal function and intensive care course data were documented. Eight patients (six females) fulfilled the study criteria and were included in the study. Their median age and weight were 4.5 months and 3.6 kg, respectively. Their mean +/- standard deviation (SD) preoperative blood urea nitrogen (BUN) and creatinine levels were 3.7 +/- 1.6 mmol/L and 55 +/- 10 micromol/L, respectively. Postoperatively, the mean BUN and creatinine levels peaked on the first postoperative day to reach 7.8 +/- 2.6 mmol/L and 76 +/- 22 micromol/L, respectively, before starting to return to their preoperative values. Two out of eight patients (25%) developed ARF after surgery, but only one of them (12.5%) required renal replacement therapy. Open heart surgery on bypass can be performed safely for children with solitary functioning kidney with a good outcome. ARF requiring renal replacement therapy might occur temporarily after bypass surgery in a minority of cases.

    RENAL cell carcinoma (RCC) in a solitary kidney presents a unique clinical challenge to urological surgeons.Partial nephrectomy (PN) or nephron-sparing surgery in this condition provides good oncological and renal fuctional outcomes with an acceptable complication rate.1,2 Long-term renal function remains stable in most patients with solitary kidneys after a reduction of more than 50% in renal mass.3 PN is a surgical procedure reserved for patients with a tumor in a solitary kidney,bilateral renal tumors,or renal function impairment.4 The challenge of preserving renal parenchyma is significantly complicated with the discovery of multiple masses in a solitary kidney because any subsequent complications may result in a significant decline in quality of life.Particularly in the case of postoperative renal failure,dialysis becomes necessary.

    Malacoplakia is a chronic inflammatory disease which specificity is pathological: Von Hansemann's cells and Michaelis-Gutmann's bodies. Renal localization is very rare. Two cases have been collected, the diagnosis having been done in the two cases on a nephrectomy specimen. Because there is no specific symptomatology to renal malacoplakia, the presence of a particular context should suggest the diagnosis and lead to renal needle biopsy. Thus nephrectomy could be avoided. The primum movins of the affection is a trouble of the phagocytosis. The place of surgery in the treatment of renal malacoplakia remains uncertain due to the lack of experience with the medical treatment. The latter is based on the prescription of cholinergic drugs, and has proved some efficacy in other localizations, as bladder.

    Metastatic pulmonary calcification (MPC) is common in patients with chronic renal failure. The authors experienced a patient with chronic renal failure and primary hyperparathyroidism by parathyroid adenoma accompanied with rapid progressions of MPC and alveolar hemorrhage. Recent chest radiographs, compared with previous chest radiographs, showed rapid accumulation of calcification in both upper lungs. Following up on the high-resolution CT scan after five years demonstrates more increased nodules in size and ground glass opacity. The patient was diagnosed with MPC and alveolar hemorrhage by transbronchial lung biopsy. We assumed rapid progression of MPC and alveolar hemorrhage in underlying chronic renal failures could be a primary hyperparathyroidism which may be caused by parathyroid adenoma detected incidentally. Therefore parathyroid adenoma was treated with ethanol injections. Herein, we have reported on CT findings of MPC with alveolar hemorrhage and reviewed our case along with other articles.

    Renal failure is a frequent complication in liver transplant recipients and is associated with increased morbidity and mortality. A variety of risk factors for the development of renal failure in the pre- and post-transplantation periods have been described, as well as at the time of surgery. To reduce the negative impact of renal failure in this population, an active approach is required for the identification of those patients with risk factors, the implementation of preventive strategies, and the early detection of progressive deterioration of renal function. Based on published evidence and on clinical experience, this document presents a series of recommendations on monitoring RF in LT recipients, as well as on the prevention and management of acute and chronic renal failure after LT and referral of these patients to the nephrologist. In addition, this document also provides an update of the various immunosuppressive regimens tested in this population for the prevention and control of post-transplantation deterioration of renal function.

    2010-05-01

    Many aspects of the management of renal replacement therapy in acute renal failure (ARF), including the appropriate assessment of dialysis adequacy, remain unresolved, because ARF patients often are not in a metabolic steady state. The aim of this study was to evaluate a system of adequacy indices for dialysis in ARF patients using urea and creatinine kinetic modeling. Kinetic modeling was performed for two different fictitious patients (A and B) with characteristics described by the average parameters for two patient groups and for two blood purification treatments: sustained low efficiency daily dialysis (SLEDD) in Patient A and continuous venovenous hemofiltration (CVVH) in Patient B, based on data from a clinical report. Urea and creatinine generation rates were estimated according to the clinical data on the solute concentrations in blood. Then, using estimated generation rates, two hypothetical treatments were simulated, CVVH in Patient A and SLEDD in Patient B. KT/V, fractional solute removal (FSR) and equivalent renal clearance (EKR) were calculated according to the definitions developed for metabolically unstable patients. CVVH appeared as being more effective than SLEDD because KT/V, FSR, and EKR were higher for CVVH than SLEDD in Patients A and B. Creatinine KT/V, FSR, and EKR were lower and well correlated to the respective indices for urea. Urea and creatinine generation rates were overestimated more than twice in Patient A and by 30-40% in Patient B if calculated assuming the metabolically stable state than if estimated by kinetic modeling. Adequacy indices and solute generation rates for ARF patients should be estimated using the definition for unsteady metabolic state. EKR and FSR were higher for urea and creatinine with CVVH than with SLEDD, because of higher K.T and minimized compartmental effects for CVVH.

    Full Text Available The levels of serum total thyroxine (TT4, triiodothyronine (TT3, free T3, (FT3 free T4 (FT4 and thyrotropin (TSH were measured in 127 clinically euthyroid patients with varying grades of chronic renal failure (CRF; and 97 healthy individuals. They were grouped as: Group I containing 93 patients on conservative management; Group II containing 34 patients on regular dialysis therapy; and Group III (normals. Group I patients showed significant decrease in TT3, TT4 and FT3 levels (p less than 0.001 as compared to Group III, whereas FT4 and TSH values in group I were not significantly altered. TT3, TT4 and FT3 levels reduced as the severity of renal damage increased. Variations in TT3, TT4, FT3, FT4 and TSH levels in Group II patients were similar to those in Group I, except for a decrease in TSH levels (p less than 0.05 as compared to normals. Several thyroid function tests are abnormal in CRF patients, however, finding of normal FT4 and TSH levels would indicate functional euthyroid status.

    Full Text Available Nowadays, diabetes mellitus (DM and hypertension are considered as the most common causes of end-stage renal disease (ESRD. In this paper, other than presenting the role of DM in ESRD, glucose metabolism and the management of hyperglycemia in these patients are reviewed. Although in several large studies there was no significant relationship found between tight glycemic control and the survival of ESRD patients, it is recommended that glycemic control be considered as the main therapeutic goal in the treatment of these patients to prevent damage to other organs. Glycemic control is perfect when fasting blood sugar is less than 140 mg/dL, 1-h postprandial blood glucose is less than 200 mg/dL, and glycosylated hemoglobin (HbA1c is 6-7 in patients with type 1 diabetes and 7-8 in patients with type 2 diabetes. Administration of metformin should be avoided in chronic renal failure (CRF because of lactic acidosis, the potentially fatal complication of metformin, but glipizide and repaglinide seem to be good choices.

    Full Text Available Background: Chronic renal failure (CRF presents with an array of cutaneous manifestations. Newer changes are being described since the advent of hemodialysis, which prolongs the life expectancy, giving time for these changes to manifest. Aim: The aim of this study was to evaluate the prevalence of dermatologic problems among patients with chronic renal failure (CRF undergoing hemodialysis. Methods: One hundred patients with CRF on hemodialysis were examined for cutaneous changes. Results: Eighty-two per cent patients complained of some skin problem. However, on examination, all patients had at least one skin lesion attributable to CRF. The most prevalent finding was xerosis (79%, followed by pallor (60%, pruritus (53% and cutaneous pigmentation (43%. Other cutaneous manifestations included Kyrle′s disease (21%; fungal (30%, bacterial (13% and viral (12% infections; uremic frost (3%; purpura (9%; gynecomastia (1%; and dermatitis (2%. The nail changes included half and half nail (21%, koilonychia (18%, onychomycosis (19%, subungual hyperkeratosis (12%, onycholysis (10%, splinter hemorrhages (5%, Mees′ lines (7%, Muehrcke′s lines (5% and Beau′s lines (2%. Hair changes included sparse body hair (30%, sparse scalp hair (11% and brittle and lusterless hair (16%. Oral changes included macroglossia with teeth markings (35%, xerostomia (31%, ulcerative stomatitis (29%, angular cheilitis (12% and uremic breath (8%. Some rare manifestations of CRF like uremic frost, gynecomastia and pseudo-Kaposi′s sarcoma were also observed. Conclusions: CRF is associated with a complex array of cutaneous manifestations caused either by the disease or by treatment. The commonest are xerosis and pruritus and the early recognition of cutaneous signs can relieve suffering and decrease morbidity.

    A 3-yr-old captive-born California sea lion (Zalophus californianus) developed Sarcocystis neurona-induced myositis and rhabdomyolysis that led to acute renal failure. The sea lion was successfully managed with fluid therapy, antiprotozoals, antibiotics, anti-inflammatories, antiemetics, gastroprotectants, and diuretics, but developed severe delayed hypercalcemia, a syndrome identified in humans after traumatic or exertion-induced rhabdomyolysis. Treatment with calcitonin was added to the management, and the individual recovered fully. The case emphasizes that animals with rhabdomyolysis-induced renal failure risk developing delayed hypercalcemia, which may be life threatening, and calcium levels should be closely monitored past the resolution of renal failure.

    The aim of the study was to determine the role of transurethralresection of prostate (TURP) in normalising renal function in men presenting with obstructive renal failure secondary to benign prostatic hyperplasia. We reviewed the cases of 14 men who presented in the last 5 years with renal impairment associated with symptoms of bladder outflow obstruction and radiological evidence of obstructive uropathy. The mean serum creatinine at presentation was 632 ng\\/mL (range 1299 - 225). The mean age at presentation was 68.2 years (range 50 - 83 years). Duration of symptoms prior to presentation ranged between 1 - 118 months (mean 21.5 months). Following catheter insertion, all patients underwent TURP. Six of the 14 patients required dialysis prior to surgery. Histology of the resected prostate confirmed benign prostatic hypertrophy and\\/or hyperplasia in all cases. Patients with carcinoma of the prostate were excluded from the study. Following TURP, 2 of the 14 men (14%) failed to void spontaneously following removal of catheter - one patient performs clean self intermittent catheterization (CSIC), the other man has an in-dwelling catheter in situ. One patient died 7 months following TURP due to a myocardial infarction. However, 8 patients, (57%) remained dialysis dependent following TURP. Two of these patients have since undergone successful renal transplantation. Of the remaining 6 patients, only 3 have normal renal function with the other 3 experiencing moderately elevated serum creatinine (range 236 - 344 ng\\/mL). In patients presenting with renal failure due to bladder outflow obstruction, TURP restores normal voiding pattern in many cases. However renal failure due to bladder outflow obstruction tends to be more refractory and only 3 of 14 patients experienced return to normal renal function post treatment.

    We retrospectively identified patients with end-stage renal disease undergoing hemodialysis treated with the mammalian target of rapamycin inhibitors as a second- and/or third-line targeted therapy after treatment failure with the tyrosine kinase inhibitors for metastatic renal cell carcinoma. Patient medical records were reviewed to evaluate the response to therapies and treatment-related toxicities. Four patients were identified. All patients had undergone nephrectomy, and one had received immunotherapy before targeted therapy. Two patients had clear cell histology, and the other two had papillary histology. All patients were classified into the intermediate risk group according to the Memorial Sloan-Kettering Cancer Center risk model. All patients were treated with everolimus as a second- or third-line therapy, and two patients were treated with temsirolimus as a second- or third-line therapy after treatment failure with sorafenib or sunitinib. The median duration of everolimus therapy was 6.7 months, whereas that of temsirolimus was 9.5 months. All patients had stable disease as the best response during each period of therapy. There were no severe adverse events. The use of mammalian target of rapamycin inhibitors in patients who previously failed to respond to tyrosine kinase inhibitors appears to be feasible in patients with end-stage renal disease requiring hemodialysis.

    Longstanding renal calculus is a risk factor of squamous cell carcinoma (SCC) of the renal pelvis. It is highly aggressive and usually diagnosed at advanced stages with a poor prognosis. We present two cases of kidney stone complications with renal pelvic SCC. These two patients had a radical nephrectomy and the dissected tissues were renal pelvic SCC. Our cases further emphasize that renal pelvic SCC should be considered in patients with longstanding renal calculus. These cases contribute greatly to an early diagnosis and early treatment, both of which will significantly minimize the damage of, and markedly improve the prognosis of, renal pelvic SCC.

    Heart Failure (HF) is a common disease with a high rate of mortality. Anemia and renal failure (RF) are often found in patients with HF associated with higher severity of the heart disease and a worse prognosis. To evaluate the prevalence of anemia and RF, as well as the association between these two conditions, in non-hospitalized patients with HF. Patients treated at the HF Outpatient Clinic of a university hospital were followed from July 2003 to November 2006. Anemia was defined as hemoglobin levels Renal function was assessed by the glomerular filtration rate (GFR), calculated by the simplified formula of the MDRD (Modification of Diet in Renal Disease) study. Of the 345 patients included in this study, 26.4% (n = 91) had anemia and 29.6% had moderate to severe renal failure (GFR anemia and a higher prevalence of renal failure was statistically significant (41.8% vs. 25.2%; p = 0.005). The patients at functional class III and IV presented a higher incidence of anemia (39.0% vs. 19.4%; p renal failure (38.2% vs. 24.8%; p = 0.007). No association was observed between anemia or renal failure and history of hypertension, diabetes, systolic function or etiology of HF. The prevalence of anemia and renal failure was high in this population and was associated with the severity of the HF (functional classes III and IV).

    Glomerular filtration rate and/or creatinine are not accurate methods for renal failure prediction. This study tested homocysteine (Hcy) as a predictive and prognostic marker for end stage renal disease (ESRD). In total, 176 subjects were recruited and divided into: healthy normal group (108 subjects); mild-to-moderate impaired renal function group (21 patients); severe impaired renal function group (7 patients); and chronic renal failure group (40 patients) who were on regular hemodialysis. Blood samples were collected, and serum was separated for analysis of total Hcy, creatinine, high sensitive C-reactive protein (CRP), serum albumin, and calcium. Data showed that Hcy level was significantly increased from normal-to-mild impairment then significantly decreases from mild impairment until the patient reaches severe impairment while showing significant elevation in the last stage of chronic renal disease. Creatinine level was increased in all stages of kidney impairment in comparison with control. CRP level was showing significant elevation in the last stage. A significant decrease in both albumin and calcium was occurred in all stages of renal impairment. We conclude Hcy in combination with CRP, creatinine, albumin, and calcium can be used as a prognostic marker for ESRD and an early diagnostic marker for the risk of renal failure.

    Primitive neuroectodermal tumor (PNET) is a malignant small round cell tumor and typically arises from bone or soft tissue in adolescents and young adults. Renal PNET is extraordinarily rare and exhibits highly aggressive biological behavior with poor prognosis.We present here a new case of renal PNET in a 31-year-old female. The patients were referred to our hospital because of left flank pain with nausea and vomiting for 1 week. A computed tomography scan revealed a 14.7 × 12.7 cm well-defined, unevenly mass lesion with both solid and cystic components and the tumor was not enhanced uniformly.A preoperative diagnosis of cystic renal cell carcinoma and urinary tract infection was made. The patient undergone anti-inflammatory therapy followed by a left radical nephrectomy. Taken with morphological pattern and immunohistochemical markers, a diagnosis of renal PNET was made. Two cycles of combined chemotherapy were executed. At the 14-month follow-up, no evidence of metastasis or recurrence was indicated.This case reminds clinicians that for adolescents and young adults with a suspicious renal mass, a diagnosis of renal PNET should be always considered. An initial surgery followed by radiotherapy and chemotherapy is suggested for the therapeutic management.

    Full Text Available The effects of keishibukuryogan on the early stage of progressive renal failure were examined in rats subjected to 5/6 nephrectomy. Keishibukuryogan, one of the traditional herbal formulations, was given orally at a dose of 1% (w/w and 3% (w/w in chow. Administration of keishibukuryogan was started at 1 week after 5/6 nephrectomy and was continued for 4 weeks. At the end of the experiment, Azan staining did not reveal any severe histological changes in the kidneys of the nephrectomized rats. On the other hand, significant increases in mRNA expressions of transforming growth factor-β1 and fibronectin related to tissue fibrosis, as examined by Reverse Transcriptase-Polymerase Chain Reaction, were observed in nephrectomized rats, and they were significantly suppressed by 3% keishibukuryogan treatment. Against gene expressions related to macrophage infiltration, 3% keishibukuryogan treatment significantly suppressed osteopontin mRNA levels, and monocyte chemoattractant protein-1 and vascular cell adhesion molecule-1 mRNA levels showed a tendency to decrease, but without statistical significance. It was also observed that 3% keishibukuryogan attenuated serum urea nitrogen and urinary protein excretion levels. From these results, it was suggested that keishibukuryogan exerts beneficial effects that result in slowing the progression of chronic renal failure.

    Full Text Available OBJECTIVE: To evaluate the clinical and laboratory characteristics of acute kidney injury (AKI in newborns followed up in our neonatal intensive care unit (NICU. MATERIAL and METHODS: This prospective study was performed in 59 newborns referred to our NICU through the completion of previously prepared forms. The Mann-Whitney U test and Student t-test were used for statistical analysis. Ethical committee approval was obtained for the study. RESULTS: Eight hundred eighteen newborns were followed up in our NICU during the study period, 59 of whom (7.2% were diagnosed as AKI. In terms of type of renal failure, 80% of the cases had prerenal AKI, 17% had renal AKI and 3% had postrenal AKI. Eighty-three percent of cases with prerenal AKI had dehydration secondary to breast-feeding malnutrition. Thirty percent of cases with renal AKI had prolonged prerenal AKI. The clinical course of AKI was oliguric/unuric in 43 cases. Mortality rate was 1.7%. CONCLUSION: These results show that the most important cause of AKI in our region is inadequate breast-feeding. We think that this problem can be signifi cantly reduced by mothers receiving adequate training regarding breast-feeding and its importance during pregnancy and after delivery, and that babies should be discharged once the physician is sure that they are breast-fed adequately by their mothers.

    Full Text Available We report the case of a 68-year-old man suffering from incremental hepatic and renal failure one month after anterior myocardial infarction. Cardiac MRI showed a pronounced apical post-AMI aneurysm, a moderate to severe mitral and tricuspid regurgitation as well as a hemodynamically highly significant 12 mm apical ventricular septal defect with a left-to-right ventricular shunt of almost 63% as the underlying cause. Heart X-ray revealed a severe LAD in-stent restenosis. CAPD catheter drainage of hydroperitoneum due to congestive liver and renal failure was provided in combination with intensified CAPD hemodialysis. Heart surgery was performed where the apical aneurysm was excised, the mitral valve was reconstructed, the IVSD was closed and the subtotally in-stent occluded LAD was bypassed. Post-surgery, the ascites were significantly reduced, and CAPD hemodialysis therapy could be terminated since the renal function gradually improved (MDRD = 25 mL/min. To our knowledge, for the first time we report successful CAPD catheter drainage of hydroperitoneum in combination with CAPD hemodialysis.

    A case of Red-bellied Black snake envenomation resulting in intravascular haemolytic anaemia, rhabdomyolysis and anuric renal failure is described in the dog. A 12-year-old female desexed Golden Retriever was presented with a 15 hour history of profuse salivation, progressive lethargy, obtundence, inappetence and collapse. Significant findings on clinical examination were pallor, icterus, tachypnoea and dyspnoea with increased respiratory sounds and crackles in all lung fields. Generalised abdominal and muscular pain was apparent and dark red-brown urine was present around the perineal region. A diagnosis of Red-bellied Black snake (Pseudechis porphyriacus) envenomation was made and the dog was treated with intravenous fluid therapy, Tiger/Brown snake antivenom, packed red cell transfusions and Intermittent Positive Pressure Ventilation. Continued clinical deterioration occurred and a diagnosis of acute renal failure secondary to myohaemoglobinuric pigmenturia was made 12 hours after admission. Intensive treatment was attempted with diuresis and volume expansion. Oliguria and subsequent anuria ensued and the dog was euthanased due to a grave prognosis and lack of clinical response to treatment. Necropsy examination revealed muscular necrosis, accumulation of fluid in the thoracic and peritoneal cavities, and marked renal tubular necrosis with intraluminal occlusion secondary to pigmentary casts.

    Transarterial chemoembolization (TACE) is included among the wide therapeutic tools for the treatment of hepatocellular carcinoma (HCC), tumour with high frequency and malignancy. The approach is invasive and, beyond the discomfort for the patient, it is charged by a number of side effects and complications. In this study we report the case of renal acute failure of hypovolemic origin, as a consequence of a TACE in a patient suffering from HCC, occurred after one week of intervention. The different possible mechanisms involved in the pathogenesis of this complication are discussed.

    Renal infection with flagellated protozoa was retrospectively evaluated in 29 reptiles, including 12 turtles, 7 tortoises, and 6 chameleons; overall, 20 species of reptiles were represented. Most cases presented with nonspecific clinical signs or a combination of several concurrent diseases. Nineteen of 29 reptiles had tubulointerstitial nephritis associated with flagellates, and this lesion was considered contributory to death in 15 cases, although concurrent diseases were frequent. Infection was invasive into the renal interstitium in three reptiles due to tubular rupture and in one chameleon also spread to adjacent tissues, coelomic cavity, and blood vessels due to renal rupture. Cytologic or ultrastructural evaluation of trophozoites in two cases was consistent with diplomonad flagellates. Renal disease was often complicated with soft-tissue mineralization and/or gout. Gastrointestinal and cloacal infection with flagellates and inflammation were frequent in reptiles in which the digestive tract was available for histopathologic examination, and this supports the possibility of infections ascending the urinary tract from the cloaca. Renal disease associated with flagellate protozoa is rare in vertebrates but appears to be relevant in reptiles, particularly chelonians and chameleons.

Methods We retrospectively reviewed all hospitalized cancer patients with CRF from Sept. 1999 to Aug. 2009 in our hospital. The epidemic characteristics and cancer sites in CRF patients were compared with those in non-CRF cancer patients and those from National Cancer Survey in 2006. Results In a total 2324 hospitalized CRF patients, cancers were found in 46 cases (2%), of whom 9 (19.6%)were treated with dialysis (hemodialysis or continuous ambulatory peritoneal dialysis), and 35 (72.9%) were detected to have cancer within 2 years after the diagnosis of CRF. Cancers were mainly found in urological or digestive systems. The average age when the cancer was detected in CRF patients was elder than that in non-CRF cancer patients. Conclusions CRF patients are at the higher risk of developing cancers than general population. Cancer screening, especially for cancers in urological and digestive systems, should be conducted in patients of older age and diagnosed with CRF within two years.

    Amylase-creatinine clearance ratio (ACCR) and amylase isoenzyme clearance were determined simultaneously in patients with chronic renal failure. ACCR in patients with compensated renal failure (3.5 +/- 0.4%) was not significantly different from normals (2.6 +/- 0.2%), while that in patients with non-compensated renal failure (6.7 +/- 0.4%) was significantly higher than that in normals. Clearance ratio of pancreatic isoamylase (Amylase-1) relative to creatinine clearance (CAmy . 1/Ccr) in patients with both compensated (5.9 +/- 1.0%) and non-compensated (6.8 +/- 0.4%) renal failure was as high as that in patients with acute pancreatitis (6.6 +/- 0.5%). On the other hand, clearance ratio of salivary isoamylase (Amylase-3) relative to creatinine clearance (CAmy . 3/CCr) in patients with compensated renal failure (1.5 +/- 0.3%) was almost the same as that in normals (2.1 +/- 0.1%), while that in patients with non-compensated renal failure was 5.9 +/- 0.7%, which was significantly higher than that in normals. The present study revealed that elevated ACCR in patients with severely impaired renal function was due to the increase of the clearance ratio for both pancreatic and salivary amylase. These facts suggested that glomerular permeability and tubular reabsorption for pancreatic and salivary amylase might play an important role on ACCR in patients with severely impaired renal function.

    Multiple myeloma (MM) is a haematological tumour that is characterised by uncontrolled proliferation of plasma cells and a significant volume of serum free light chains (sFLCs), which can cause acute renal failure due to intratubular precipitation, resulting in cast nephropathy. Acute renal failure is a complication that can arise in more than 20% of patients with multiple myeloma, half of which will require dialysis. We report our experience with 13 patients who were treated with dialysis using high cut off filters (HCO) between July 2011 and February 2015. A total of 6 consecutive 6-hour sessions were performed using a 2.1 m(2) HCO filter (Theralite® by Gambro®). Afterwards, further 6-hour sessions were continued on alternate days. A total of 151 sessions were conducted, with an average of 11.6 sessions per patient (range 6-27). The treatment proved to be effective in removing both kappa and lambda sFLCs, resulting in a 93.7% fall in sFLCs by the end of treatment. The average reduction was 57.7% per dialysis session. 10 out of the 13 cases recovered sufficient renal function to become independent of dialysis. There were no major changes in albumin levels using an infusion protocol of 2 50-mL vials of 20% albumin at the end of the dialysis session. Combination treatment with chemotherapy and long dialysis with HCO filters was effective in reducing the sFLC levels and recovering sufficient renal function in 77% of cases. With HCO filters, significant cost savings are achieved, contrary to what was previously believed. Copyright © 2016 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U.

    A series of 46 patients with obstructive disease of the bile ducts complicated by acute renal failure (ARF) is presented. The patients exhibited obstructive jaundice with prevalence of conjugated bilirubine. In 80% of the cases biliary obstruction was associated with cholangitis. Disturbances of the liver function (from mild cholestasis to biliary cirrhosis) were also present. The renal damage was due to biliary disorders and was either present on admission (33 cases) or developed postoperatively (13 cases). Most of the patients presented nonoliguric ARF as well as poor perfusion resulting from decreased circulating blood volume (dehydration and electrolyte loss). Among the criteria used to determine the type of ARF, the urinary/plasma creatinine ratio less than 10 and urinary/plasma osmolarity ratio less than 1.1 were the most valuable. Management of ARF by dialysis alone was not satisfactory. Attention is called to the surgical treatment of the biliary disorder as being essential to prognosis. Patients not treated by radical surgery died in proportion of 87 to 100%. From the rest of 18 patients in whom the operation provided an adequate biliary drainage, in 15 the renal function was restored and 12 survived. Better prognosis in these patients was dependent not only on the ability to cure the cholestasis and infection, but on the early surgical treatment. The ultimate prognosis depends on the improvement of the liver function.

    Full Text Available Selenium (Se is an essential trace element in human and animal nutrition. It is also widely utilized in industrial processes. Reports of acute selenium toxicity in humans are rare. We report a case of a 23-year-old female who consumed about 100 mL of liquid selenite broth and presented with severe nausea, vomiting, abdominal pain, hematemesis and acute renal failure (ARF. The serum selenium level was significantly increased. Gastro-duodenoscopy revealed severe corrosive gastritis. Renal biopsy showed features of acute tubular necrosis (ATN, affecting primarily the proximal tubules. The patient was managed with gastric lavage, blood transfusions, infusion of fresh frozen plasma (FFP and platelet concentrates and hemo-dialysis. The patient was discharged five weeks after admission and her renal functions reco-vered completely by eight weeks after admission. She continues to be on regular follow-up for any possible sequelae of mucosal corrosive damage. This case highlights a case of selenium intoxication from selenite broth resulting in ARF and corrosive gastritis. The recovery was complete.

    The present study comprises of 10 dogs of either sex with primary indication of azotaemia. All the dogs were subjected to detailed clinical, haematobiochemical, urinalysis, and microbiological examination along with radiographical and ultrasonographical examination. Based on the ultrasonographic structural abnormalities, the different renal affections associated with CRF in majority of dogs were diagnosed. The different affections included "end-stage" kidneys (n = 4), hydronephrosis (n = 1), renomegaly (n = 1), nephritis (n = 1), nephrolithiasis (n = 1), nephrocalcinosis (n = 1), and renal cyst (n = 1). The significant ultrasonographic features in these affections included small kidneys with loss of corticomedullary demarcation ("end-stage" kidneys); increased cortical echogenicity (nephritis); dilation of the renal pelvis, separation of the central renal sinus with anechoic space, atrophy of renal medulla, (hydronephrosis); enlarged kidneys with increased overall echogenicity of renal cortex (renomegaly and associated nephritis); hyperechoic-mineralized structure with shadowing (nephrolithiasis); diffuse, small, multiple hyperechoic structures in the renal parenchyma with distal acoustic shadowing (nephrocalcinosis); small spherical intercortical anechoic structures fluid (renal cysts). In the present study, ultrasound proved to be a quick, convenient, and sensitive modality in detecting alterations in renal size and parenchymal architecture. All the dogs so diagnosed with CRF were rendered conservative medical treatment to control clinical signs of uraemia; maintain adequate fluid, electrolyte, and acid/base balance; provide adequate nutrition; minimize progression of renal failure.

    Neuropeptide Y (NPY) is coreleased with norepinephrine and stimulates vasoconstriction, vascular and cardiomyocyte hypertrophy via Y1 receptors (R) and angiogenesis via Y2R. Although circulating NPY is elevated in heart failure, NPY's role remains unclear. Activation of the NPY system was determined in Wistar rats with the aortocaval (A-V) fistula model of high-output heart failure. Plasma NPY levels were elevated in A-V fistula animals (115.7 +/- 15.3 vs. 63.1 +/- 17.4 pM in sham, P renal failure (urinary Na(+) excretion renal blood flow (RBF), and death within 5-7 days (DECOMP). Cardiac and renal tissue NPY decreased with heart failure, proportionate to the severity of renal complications. Cardiac and renal Y1R mRNA expression also decreased (1.5-fold, P failure. In contrast, Y2R expression increased up to 72-fold in the heart and 5.7-fold in the kidney (P failure and cardiac hypertrophy. Changes in receptor expression were confirmed since the Y1R agonist, [Leu31, Pro34]-NPY, had no effect on RBF, whereas the Y2R agonist (13-36)-NPY increased RBF to compensate for disease. Thus, in this model of heart failure, cardiac and renal NPY Y1 receptors decrease and Y2 receptors increase, suggesting an increased effect of NPY on the receptors involved in cardiac remodeling and angiogenesis, and highlighting an important regulatory role of NPY in congestive heart failure.

    The clinical course and medical treatment of patients with congestive heart failure (CHF) complicating acute myocardial infarction (AMI) are not well established, especially in patients with concomitant renal dysfunction. We performed a retrospective analysis of the prospective Korean Acute Myocardial Infarction Registry to assess the medical treatments and clinical outcomes of patients with CHF (Killip classes II or III) complicated by AMI, in the presence or absence of renal dysfunction. Of 13,498 patients with AMI, 2769 (20.5%) had CHF on admission. Compared to CHF patients with preserved renal function, in-hospital mortality and major adverse cardiac events were increased both at 1 month and at 1 year after discharge in patients with renal dysfunction (1154; 41.7%). Postdischarge use of aspirin, betablockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, or angiotensin II receptor blockers and statins significantly reduced the 1-year mortality rate for CHF patients with renal dysfunction; such reduction was not observed for those without renal dysfunction, except in the case of aspirin. Patients with CHF complicating AMI, which is accompanied by renal dysfunction, are at higher risk for adverse cardiovascular outcomes than patients without renal dysfunction. However, they receive fewer medications proven to reduce mortality rates.

    A 77-year-old male was hospitalized due to haematuria and developed septicaemia. He received dabigatran due to chronic atrial fibrillation. Doses were reduced because of renal failure according to guidelines. The patient showed extensive changes in his entire coagulation system. Due to renal fail...... failure forced diuresis was not possible, and continuous dialysis was performed. Patients with renal failure should be monitored closely - if there are any sign of bleeding it is important to consider change of anticoagulant therapy as long as an antidote does not exist....

    Advanced renal failure occurred in nine adult sickle cell disease patients. There were six men and three women with a mean age of 38.6 years. Eight patients had homozygous SS disease, one had sickle cell thalassemia. Three patients had acute renal failure from which they partially recovered. Six developed endstage kidney disease requiring dialysis. Two of these received a kidney transplant, and there was one death in the immediate postoperative period. Angina pectoris, hyperkalemia, and severe anemia complicated chronic dialysis, suggesting that early transplantation should be considered for sickle cell anemia patients with renal failure.

    We report a 35 month-old boy with acute renal failure caused by an obstructive ureteral stone associated with norovirus gastroenteritis. He visited his family physician because of fever, abdominal pain and vomiting. He was diagnosed as acute gastroenteritis. The symptoms relieved once, but abdominal pain and vomiting recurred two days after the visit and the volume of urine decreased. He was diagnosed as norovirus gastoenteritis and acute renal failure which was unresponsive to fluid replacement. Ultrasound study of the abdomen showed a solitary kidney with mild hydronephrosis. He was then admitted to our hospital. He was finally diagnosed as acute postrenal failure due to obstructive ureteral stone with left solitary kidney by abdominal computer tomography (CT). We performed transurethral catheterization immediately. The creatinine and blood urea nitrogen returned to normal level in 2 days. The CT performed on the 28th day post operation showed disappearance of the stone after uric alkalization. Recently, some cases of postrenal failure due to bilateral obstructive ureteral stones, mainly ammonium acid urate stones, associated with viral gastroenteritis were reported. As clinical features, they are common in boys three years or younger after an episode of rotavirus gastroenteritis with high uric acid concentration. By far, the most common cause of acute renal failure in patients with severe gastroenteritis is prerenal failure resulting from hypovolemia. But postrenal cause due to bilateral obstructive stones should be taken in a consideration.

    Full Text Available Introduction: Recent single-site studies and case reports have linked atazanavir (ATV with the occurrence of nephrolithiasis. The purpose of this study was to estimate and compare the incidence rate of nephrolithiasis and to characterize the occurrence of subsequent renal failure among patients on ATV, other protease inhibitors (PIs and PI-free regimens using real world data. Materials and Methods: This was a retrospective cohort analysis using claims data from a US commercial and a US public health insurance database (Medicaid spanning 2003–2011 and 2006–2011, respectively. We identified adult HIV patients who were prescribed ATV, other PIs or PI-free regimens with at least 6 months of continuous enrolment prior to the index claim. Nephrolithiasis was defined as an inpatient or outpatient ICD-9 diagnosis code for nephrolithiasis or an associated condition, plus an imaging/corrective procedure code. Renal failure was also identified using diagnosis codes among patients experiencing nephrolithiasis. Hazard ratios were estimated using propensity score (PS adjusted Cox regression, crude and adjusted for demographics, baseline comorbidities and comedications. Results: A total of 14,477 patients (ATV: 4,150; other PIs: 4,153; PI-free: 6,174 were identified in the commercial database: 83% male and 20% age ≥50 years. In the Medicaid database, 9,104 patients (ATV: 3,460; other PIs: 3,117; PI-free: 2,527 were identified: 53% male and 25% age ≥50 years. There were significant baseline differences in demographics, comorbidities and concomitant medications among the three cohorts. In adjusted analyses, ATV use was not significantly associated with nephrolithiasis when compared to other PIs. When ATV was compared to PI-free regimens, a positive association was observed in the commercial insurance but not the Medicaid database. In both databases, previous history of nephrolithiasis was the strongest predictor of nephrolithiasis in the ATV

    急性乙型肝炎并发肾功能衰竭十分少见,其肝外表现通常为血清病样表现,包括发热、皮疹和多动脉炎.我们报道1位男性34岁患者,诊断为急性HBV感染,临床表现为肝脏和肝外多器官的损害,以肾功能衰竭为突出的表现,推测是由循环免疫复合物沉积在肾小球血管壁,导致膜性肾小球肾炎而引起的.患者接受了血液透析和持续性血液滤过治疗、常规的护肝和对症治疗及恩替卡韦抗病毒治疗,最后痊愈.%Acute hepatitis B is often accompanied by serum-sickness-like syndrome, including fever, rash and polyarteritis. Acute renal failure in acute hepatitis B is extremely rare. A 34-year-old male presented to our hospital, with initial laboratory values showing acute hepatitis B virus infection. The clinical feature indicated hepatitis and extrahepatic impairments of kidney, myocardium and platelet, and renal failure was the prominent manifestation which appeared early in the day 3 of onsetting, including 19 days of oliguria and 6 days of anuria. Kidney impairment was presumed owing to deposition of immune complex which resulted in membranous glomerulonephritis. The patient accepted hemodialysis and continuous renal replacement therapy, and entecavir was applied to depress HBV DNA copying and may have shortened the course of the disease. At 2-month follow up, the patient healed completely.

    Full Text Available The purpose of this study was to evaluate periodontal disease (PD in dogs with chronic renal failure (CRF and to compare it to PD in dogs with normal renal function (NRF. Twelve dogs with CRF and 24 dogs with NRF, all presenting dental pocket formation, were compared. In all dogs, serum creatinine, blood urea nitrogen, urine specific gravity and total red and white blood cells were determined. A complete oral examination was also performed including evaluation of bacterial plaque, gingivitis, gingival recession, pocket, calculus, dental mobility, dental loss, and ulcers. These data were used to calculate plaque index (PI, gingival index (GI and periodontal destruction index (PDI. PD was graded as mild, moderate or severe based on the results. Mild, moderate or severe PD was observed in dogs with NRF, whereas dogs with CRF presented either mild or severe PD. Dogs with NRF showed higher involvement of the maxillary teeth, whereas dogs with CRF showed a higher involvement of the mandibular teeth. Plaque index was significantly higher in dogs with NRF. It was concluded that lesion distribution and periodontal disease progression may be altered in dogs with CRF, and gingival inflammatory response differs in dogs with NRF and CRF regarding to the stage of periodontal disease.

    Heart failure syndrome results from compensatory mechanisms that operate to restore - back to normal - the systemic perfusion pressure. Sympathetic overactivity plays a pivotal role in heart failure; norepinephrine contributes to maintenance of the systemic blood pressure and increasing preload. Cardiac norepinephrine spillover increases in patients with heart failure; norepinephrine exerts direct toxicity on cardiac myocytes resulting in a decrease of synthetic activity and/or viability. Importantly, cardiac norepinephrine spillover is a powerful predictor of mortality in patients with moderate to severe HF. This provided the rationale for trials that demonstrated survival benefit associated with the use of beta adrenergic blockers in heart failure with reduced ejection fraction. Nevertheless, the MOXCON trial demonstrated that rapid uptitration of moxonidine (inhibitor of central sympathetic outflow) in patients with heart failure was associated with excess mortality and morbidity, despite reduction of plasma norepinephrine. Interestingly, renal norepinephrine spillover was the only independent predictor of adverse outcome in patients with heart failure, in multivariable analysis. Recently, renal sympathetic denervation has emerged as a novel approach for control of blood pressure in patients with treatment-resistant hypertension. This article summarizes the available evidence for the effect of renal sympathetic denervation in the setting of heart failure. Key messages Experimental studies supported a beneficial effect of renal sympathetic denervation in heart failure with reduced ejection fraction. Clinical studies demonstrated improvement of symptoms, and left ventricular function. In heart failure and preserved ejection fraction, renal sympathetic denervation is associated with improvement of surrogate endpoints.

    Watermelon stomach or gastric antral vascular ectasia (GAVE) syndrome is an uncommon cause of sometimes severe upper gastro-intestinal bleeding. Essentially based on a pathognomonic endoscopic appearance, its diagnosis may be unrecognised because mistaken with portal hypertensive gastropathy, while treatment of these two entities is different. Its etiopathogeny remains still unclear, even if it is frequently associated with different systemic illnesses as hepatic cirrhosis, autoimmune disorders and chronic renal failure. The mechanism inducing these vascular ectasia may be linked with mechanical stress on submucosal vessels due to antropyloric peristaltic motility dysfunction modulated by neurohormonal vasoactive alterations. Because medical therapies are not very satisfactory, among the endoscopic modalities, argon plasma coagulation seems to be actually the first-line treatment because the most effective and safe. However, surgical antrectomy may be sometimes necessary. Recently GAVE syndrome appeared as a new adverse reaction of imatinib mesylate, one of the tyrosine kinase inhibitors used in chronic myeloid leukemia, and we report here the observation of such a pathology in one patient treated at the same time by haemodialysis and by imatinib mesylate for chronic myeloid leukemia.

    Manganese (Mn) is an essential trace element involved in the formation of bone and in amino acid, lipid and carbohydrate metabolism. Mn excess may be neurotoxic to humans, affecting specific areas of the central nervous system. However, relatively little is known about its physiological and/or toxicological effects, and very few data are available concerning the role of Mn in chronic renal failure (CRF). This paper describes a 12-month study of the evolution of plasma Mn levels in predialysis patients with CRF and the relationship with energy and macronutrient intake. The participants in this trial were 64 patients with CRF in predialysis and 62 healthy controls. Plasma levels of creatinine, urea, uric acid, total protein and Mn were measured. The glomerular filtration rate (GFR) was calculated using the Cockcroft-Gault index. The CRF patients had higher plasma levels of creatinine, urea, uric acid and Mn and a lower GFR than the controls. Plasma Mn was positively correlated with creatinine, plasma urea and plasma uric acid and was negatively correlated with the GFR and the intake of energy and macronutrients. In conclusion, CRF in predialysis patients is associated with increases in circulating levels of Mn.

    Objective:To evaluate hearing threshold and the severity of hearing loss at different frequencies in patients with chronic renal failure (CRF), and to analyze the role of duration of disease on hearing threshold in patients of CRF by measuring pure-tone audiometry (PTA) and distortion-product otoacoustic emission (DPOAE). Methods: There were analysed 61 subjects (122 ears) from which 12 were patients starting hemodialise (A), 24 subjects were patients undergoing hemodialise over a year (B), 15 subjects were patients undergoing conservative treatment (C) and 10 controls (D). We did hearing evaluation by testing them using tympanometry, PTA and DPOAEs. Other parameters (blood pressure, body weight, blood chemistries) were also evaluated. Results:It was found a severe high-frequency hearing loss among patients with CRF comparing to the control group. Duration on haemodialysis treatment does not seem to have a significant impact on the incidence of hearing loss, although the method of treatment may influence the impact of the disease on hearing. Hearing loss among patients with CRF seemed to deteriorate further a year after the first evaluation. Conclusions:DPOAE raised the percentages of detection of SNHL indicating that it is a better technique than the conventional PTA for evaluation of hearing acuity.

    This study investigates the effects of lysine-induced acute renal failure. Female dogs received a lysine hydrochloride (lysine) of 4500 mg/kg/day (3.75 ml/kg/hr) for 3 consecutive days. The dogs were observed for clinical signs. Body weights were recorded, food consumption and water consumption calculated, and urinalysis and blood biochemistry were performed daily. Plasma samples for amino acid determinations were obtained from all dogs, which were necropsied on Day 3. Histopathological examinations were done on all test animals. Compound-related findings include the following. Blood biochemistry results showed increases in ammonia, blood urea nitrogen, blood urea nitrogen/creatinine ratio, and creatinine. Urinary changes consisted of increases in urine volume, total protein, albumin, gamma-glutamyl transpeptidase, and N-acetyl-beta-D-glucosaminidase. In addition, macroscopic findings consisted of pale, congested capsule; microscopic findings consisted of hypertrophy of proximal convoluted tubule (mainly S1 segment), and degeneration/desquamation of urinary tubule (mainly S3 segment with hyaline casts) in the kidney. From these findings, it can be concluded that lysine is nephrotoxic in dogs. Nephrotoxicity of lysine may relate to direct tubular toxicity and to tubular obstruction.

    We performed oral fat loading tests in 10 patients with chronic renal failure (CRF) on hemodialysis (5 children and 5 adults). Fat absorption was measured by hourly determination of serum triglycerides (TG), cholesterol (CHOL), and lipoproteins (LP) after oral administration of a 'milkshake' containing 50 g of fat of dairy origin. 10 age-matched healthy volunteers with normal fasting serum TG levels and 10 subjects with fasting hypertriglyceridemia served as controls. Mean fasting serum TG levels in CRF patients were elevated compared to normal controls (177.6 +/- 14.6 mg/dl, 2.0 +/- 17 mmol/l vs. 91.0 +/- 10.5 mg/dl, 1.03 +/- 12 mmol/l). 6 patients (4 adults, 2 children) had type IV LP patterns and 2 patients (both children) showed type IIb hyperlipidemia. In only 2 patients, 1 child and 1 adult were TG, CHOL and LP electrophoresis all normal. The oral fat loading test in all CRF patients showed delayed appearance of TG and chylomicrons (CHYL) in the bloodstream i.c. impaired or slow absorption of fat from the gut. In contrast to normal and hypertriglyceridemic controls, TG and CHYL levels in CRF did not decrease by 5 h after the oral fat load. This study demonstrates impaired intestinal fat absorption in children and adults with CRF.
