    Full Text Available PURPOSE: Although nonselective nonsteroidal anti-inflammatory drugs (nsNSAIDs and opioids are effective treatments for acute renal colic, they are associated with adverse events (AEs. As cyclooxygenase-2 selective NSAIDs may provide a safer alternative, we compared the efficacy and safety of parecoxib versus an nsNSAID in subjects with acute renal colic. MATERIALS AND METHODS: Phase IV., multicenter, double-blind, noninferiority, active-controlled study: 338 subjects with acute renal colic were randomized to parecoxib 40 mg i.v. plus placebo (n = 174 or ketoprofen 100 mg IV plus placebo (n = 164. 338 subjects with acute renal colic were randomized to parecoxib 40 mg IV (n = 174 or ketoprofen 100 mg IV(n = 164 plus placebo. Subjects were evaluated 15, 30, 45, 60, 90 and 120 minutes after treatment start and 24 hours after discharge. Primary endpoint was the mean pain intensity difference (PID at 30 minutes by visual analog scale (VAS (per-protocol population. An ANCOVA model was used with treatment group, country, and baseline score as covariates. Non-inferiority of parecoxib to ketoprofen was declared if the lower bound of the 95% confidence interval (CI for the difference between the two groups excluded the pre-established margin of 10 mm for the primary endpoint. RESULTS: Baseline demographics were similar. The mean (SD mPID30 min was 33.84 (24.61 and 35.16 (26.01 for parecoxib and ketoprofen, respectively. For treatment difference (parecoxib-ketoprofen the lower bound of the 95% CI was 6.53. The mean change from baseline in VAS 30 minutes after study medication was ~43 mm; AEs were comparable between treatments. CONCLUSIONS: Parecoxib is as effective as ketoprofen in the treatment of pain due to acute renal colic, is well tolerated, and has a comparable safety profile.

    Full Text Available Abstract Background There is great variation in the Accident and Emergency workload and location of Urology services in UK hospitals. This study investigated the relationship of the initial management of acute renal colic with the department workload plus local facilities including location of X-ray and urology services in UK Accident and Emergency (A&E departments. Methods A&E departments in each of the 11 UK Deanery regions were stratified based on departmental workload, namely small; 30,000 to 50,000 (medium; 50,000 to 80,000 (large and >80,000 (very large patients per year. One third of departments were selected in each group leading to a sample size of 106. A questionnaire was administered. Associations between categorical variables were investigated using the chi-squared test and when not valid, Fisher's Exact test was employed. Differences between groups in ordinal variables were investigated using the Mann-Whitney test. Results All questionnaires were returned. Twenty-nine units (27.4% did not perform any radiological investigation on renal colic patients. The number of radiological investigations that were available to departments was associated with workload (P = 0.003; with 57.1% of the small departments performing none and at least 82.8% of units in the other categories performing at least one. Of those departments with X-ray facilities in or adjacent to the department, 63% performed an intravenous urography (IVU compared to 25% of those departments without (P = 0.026. Of those departments with on-site urology services, 86% performed at least one radiological investigation compared to 52% of units without such services (P = 0.001. Department workload was associated with the first choice analgesia (NSAIDs or parenteral opiates (P = 0.011. Of the small departments, 64.3% used NSAIDs, 21.4% used parenteral opiates and 14.3% used neither. In comparison, NSAIDS were used by at least 87%, and opiates by at most 12.5% of units in each of

    Aim: To evaluate a new imaging pathway for the investigation of patients presenting with suspected acute renal colic. Materials and methods: A retrospective review of 500 consecutive cases of suspected acute renal colic was undertaken to evaluate the initial results of a new imaging pathway introduced at our institution, which completely replaced the intravenous urogram (IVU) with unenhanced multidetector CT (CT KUB). Results: The positive rate for urolithiasis was 44% (221/500), the negative rate 46% (229/500) and the rate of other significant findings was 12% (59/500). Female patients had a low positive rate compared with male patients (27.5 versus 57.5%; p < 0.001). Urological intervention was required in 28% (61/221) and these patients had a larger average stone size (6.6 versus 3.7 mm; p < 0.001) and the stone was located more proximally. Out-of-hours imaging was performed in 37% (186/500), and these patients had a higher positive rate (52 versus 40%; p < 0.001). Other findings included a wide range of acute non-urological conditions. Conclusion: The feasibility of replacing the acute IVU with CT KUB in the initial assessment of suspected acute renal colic was demonstrated in the present study. The technique enables rapid diagnosis of urolithiasis, stratification of patients likely to proceed to urological intervention, and prompt diagnosis of a variety of other acute pathological conditions.

    Twenty patients free from urodynamic disturbances and 26 patients presenting with nephritic colic were studied in an ultrasound investigation into the urinary system and renal arteries. The examinees divided into the following groups: controls, patients with acutely congestive kidney, patients with calculi in the ureter without manifest obstruction, and patients with renal calculi. There were three pregnant women in the above series. Patients with acutely congestive kidney demonstrated significant elevation (P < 0.05) of PI, IR, S/D, and decrement of Vmin by comparison with controls. The results obtained with Doppler Ultrasound (DU) formed the basis for catheterization of the ureter in 1 pregnant female examinee, for endovesical ureterolithoextraction in 1 patient, with three others having had their calculi reduced to fine particles. Employment of DU to study renal arteries in patients presenting with disordered urodynamics of the upper urinary tract is helpful when choosing between therapeutic policies to be adopted, with particular emphasis being given to the management of pregnant female patients.

    Renal colic is a common reason for presentation to emergency departments, and imaging has become fundamental for the diagnosis and clinical management of this condition. Ultrasonography and particularly noncontrast computed tomography have good diagnostic performance in diagnosing renal colic. Radiologic management will depend on the tools available at the center and on the characteristics of the patient. It is essential to use computed tomography techniques that minimize radiation and to use alternatives like ultrasonography in pregnant patients and children. In this article, we review the epidemiology, clinical and radiologic presentations, and clinical management of ureteral lithiasis.

    Full Text Available Objective: To compare the efficacy of desmopressin (DDAVP, tramadol and indomethacin on pain intensity of patients with acute renal colic caused by urolithiasis. Methods: This prospective, randomized clinical trial was conducted between July 2005 and July 2006 including 120 patients (70 men and 50 women, mean age 38.2±5.8 years referring to emergency room of Shahid Faghihi hospital with renal colic caused by urolithiasis without any previous treatment. The patients were randomly assigned to three groups: group A received tramadol 50mg intramuscularly (n=40, group B received desmopressin 40 µg intranasally (n=40 and group C received indomethacin 100mg rectally (n=40. The pain was assessed both on admission and 30 minutes after the intervention. The pain intensity and the side effects were compared between two study groups. Results: There was no significant difference between two study groups regarding the baseline characteristics. The intensity of pain of presentation was almost similar in all groups. In group A, 30 patients (75%, in group B, 15 patients (37.5% and in group C, 19 patients (47.5% had complete pain relief. The pain intensity decreased significantly after the intervention within all three groups ( p<0.001. Conclusion: According to the results of the current study, rectal indomethacin, intramuscular tramadol and intranasal desmopressin are effective and safe routs of controlling pain in acute renal colic secondary to urolithiasis. Tramadol was the most effective agent in controlling the pain. Clinical Trial Registry: The current study is registered with Iranian Registry for Clinical Trials (www.irct.ir; IRCT2015030919470N18

    With the introduction of a 3-T scanner, magnetic resonance urography (MRU) may be an alternative imaging modality for evaluation of acute renal colic. We performed a prospective study to compare the performance of computed tomography (CT) with half-Fourier single shot turbo spin-echo (HASTE) MRU in the evaluation of patients with suspected renal colic. Patients presenting to the emergency department with acute renal colic were eligible for inclusion. Following a standard CT stone evaluation, patients underwent a non-contrast HASTE MRU study with a 3-T scanner. The presence of perinephric fluid, hydronephrosis, ureteral obstruction, and calculus was assessed. A total of 22 patients completed the study. Twenty (91 %) were diagnosed with an upper tract stone by radiographic findings. MRU detected a discrete stone in 50 % of the patients with stones detected by CT. Perinephric fluid was noted in 12 MRUs, compared to 7 CTs. Using CT as the reference standard, the combination of stone or perinephric fluid and ureteral dilation gave MRU a sensitivity of 84 %, specificity of 100 %, and accuracy of 86 % (95 % CI 0.72-1.0). HASTE MRU with a 3-T MR scanner can reliably detect the presence of upper urinary tract obstruction. Although CT imaging remains the superior modality with which to detect calculi, MRU detects a greater number of secondary signs of upper tract obstruction. For situations in which the use of ionizing radiation is undesirable, MRU is a reasonable imaging alternative.

    Full Text Available Renal infarction is a rare cause of acute kidney injury which could lead to permanent loss of renal function. A prompt diagnosis is necessary in order to achieve a successful revascularization of the occluded artery. Given the rarity of the disease and the paucity of the reported cases in the previous literature a high index of suspicion must be maintained not only in the classical cardiac sources of systemic emboli (atrial fibrillation, dilated cardiomyopathy, or endocarditis, but also in the situations when a hypercoagulable state is presumed. The unspecific presenting symptoms often mask the true etiology of the patient’s complaints. We present here a rare case of renal infarction that occurred in the setting of a hypercoagulable state, in a female patient with a history of breast cancer and documented hepatic metastases.

    Computed tomography is considered as an imaging modality of choice in acute ureteric colic. However due to concerns regarding radiation exposure, sonograms are re-emerging as imaging methods in such situations. To evaluate the role of sonography in detection of calculus in acute ureteric colic. Total 384 patients were enrolled. Hydronephrosis was graded as mild, moderate or severe. Calculus was detected as an intraluminal echogenic focus with distal shadowing with twinkling artifact. Number, size and position of the calculi were assessed. Patients were categorized into four groups:I. ureteric colic only II. ureteric colic with hematuria III. ureteric colic with hydronephrosis and IV. ureteric colic with hematuria and hydronephrosis and then the possibility of detection of calculi has been compared among these groups. Out of 384 patients, 254 were found to have calculi ranging between 2.7-27 mm. Nineteen had in the pelvis/ pelviureteric junction, 64 in proximal ureter, 125 in distal ureter, 6 at iliac crossing and 40 at vesicoureteric junction. Two hundred forty one had single and 14 had multiple calculi. Calculus detection is easier in category III and IV patients. The sensitivity and specificity of ultrasonography were 87.98% and 93.07%. Degree of hydronephrosis is strongly correlated with the number of calculi but weakly correlated with the size of the calculus. Sonogram can be used in all cases of acute ureteric colic. Hydronephrosis is the most important finding because it paves the way out for the detection of calculus.

    To evaluate renal colic frequency in different seasons and around full moon. A total of 1481 patients with renal colic were studied retrospectively addressing days of a month both in solar and lunar calendar. The mean age of the patients was 57 ± 13 years. Total admissions in summer was 613; of which 288 (41%), 199 (39%), and 126 (43%) were in years 2002, 2003, and 2004, respectively. The highest frequencies in solar calendar were on days 2 (56), 20 (63), and 27 (59) and the lowest were on days 6 (36), 22 (38), 26 (34), and 31 (31). We did not find any statistically significant association according to solar calendar (P = .3). In lunar calendar, most of the admissions were on day 15 (69) and the lowest rates were on days 1 (25) and 30 (26), which was statistically significant (P = .04). Renal colic frequency is not correlated with solar calendar, but its highest frequency in lunar calendar is in the middle of the month period. Although we found a correlation between full moon effect and renal tide, but this is a new window for further studies.

    Full Text Available Introduction: Renal colic can be managed by preventing the contraction movements of ureter muscles. By reducing acetylcholine in the nerve terminals, magnesium sulfate could be effective in this regard. The aim of this study is to investigate the effect of magnesium sulfate on acute renal colic pain relief. Method: The present study was a double-blind clinical trial in which the patients suffering from acute renal colic were randomly divided into 2 groups of who either received standard protocol (intravenous infusion of 0.1 mg/Kg morphine sulfate, 30 mg of Ketorolac, and 100 ml normal saline as placebo/15 minutes or standard protocol plus 15 mg/Kg of intravenous magnesium sulfate 50%/100 ml normal saline/15 minutes. Severity of patients’ pain was measured by visual analogue scale (VAS at baseline, and 30 and 60 minutes after infusion. The collected data were analyzed using STATA statistical software. Results: 100 cases were randomly allocated to intervention or control group. The two groups were similar in baseline pain score and demographic characteristics. At 30 and 60 minutes, mean pain score was less in the intervention group compared to the control group. Moreover, the difference between the two groups was statistically significant regarding the additional amount of morphine, suggesting that the intervention group needed less additional morphine than the control group. Conclusion: The results of this study showed that Magnesium sulfate can be used as an adjunct drug in treatment of patients suffering from renal colic. It not only alleviates the pain in the patients, but also diminishes the need for pain medications.

    Full Text Available Several studies have reported that symptoms of anxiety and depression are significantly associated with diseases characterized by painful crises. However, there is little information about the psychological aspects of recurrent painful episodes of renal stone disease. Our objective was to evaluate the association of symptoms of anxiety, depression and recurrent painful renal colic in a case-control study involving 64 subjects (32 cases/32 controls matched for age and sex. Cases were outpatients with a confirmed diagnosis of nephrolithiasis as per their case history, physical examination, image examination and other laboratory exams. Patients had a history of at least two episodes within a 3-year period, and were currently in an intercrisis interval. The control group consisted of subjects seen at the Ophthalmology Outpatient Clinic of this University Hospital with only eye refraction symptoms, and no other associated disease. Symptoms of anxiety were evaluated by the State-Trait Anxiety Inventory and symptoms of depression by the Beck Depression Inventory. Statistically significant differences were observed between patients with nephrolithiasis and controls for anxiety state (P = 0.001, anxiety trait (P = 0.005 and symptoms of depression (odds ratio = 3.74; 95%CI = 1.31-10.62. The Beck Depression Inventory showed 34.5% of respondents with moderate and 6% with severe levels of depression. There was a significant linear correlation between symptoms of anxiety (P = 0.002 and depression (P < 0.001 and the number of recurrent colic episodes (anxiety-state: P = 0.016 and anxiety-trait: P < 0.001. These data suggest an association between recurrent renal colic and symptoms of both anxiety and depression.

    Full Text Available Introduction: Although the synergistic effects of opioids and other analgesic drugs such as non-steroidal anti-inflammatory drugs (NSAIDs have been established in relieving acute pain due to renal calculi, no studies today have evaluated the concomitant administration of opiates and other drugs with analgesic effects, such as serotonin re-uptake inhibitors. Considering the high prevalence of renal colic, the present study was carried out to compare the effect of concomitant prescription of morphine and a placebo with that of morphine and citalopram on the management of acute pain due to renal calculi. Methods: The present double-blind randomized clinical trial was carried out from October 2012 to March 2013 in the Al-Zahra educational Hospital in Isfahan, Iran. A total of 90 patients with acute renal colic pain were randomly divided into two groups of 45 subjects. The subjects in one group received morphine/ placebo and another one morphine/citalopram. The patients’ pain severity was determined by visual analogue scale (VAS before and 20 minutes after administration of medications. In case of persistent pain the second or even third dose was administered and the pain severity was once again determined. Data were analyzed with STATA 11.0 using chi-squared, two-way ANOVA, Bonferroni post hoc test, and log rank test. Results: The decrease in pain severity in the morphine/citalopram group was significantly compared to the morphine/placebo group and the time before administration of the medications (p<0.001. In contrast, administration of morphine/placebo did not have a significant effect on pain severity at this interval (p=0.32. Kaplan-Meier curve showed that the first injection was successful in relieving pain in 15 (33.3% and 26 (57.8% subjects in the morphine/placebo and morphine/citalopram groups, respectively. The second injection of these medications resulted in therapeutic success in 35 (87.8% and 42 (95.6% subjects in the above groups

    Few previous studies have examined the association between temperature and renal colic in developing regions, especially in China, the largest developing country in the world. We collected daily emergency ambulance dispatches (EADs) for renal colic from Guangzhou Emergency Center from 1 January 2008 to 31 December 2012. We used a distributed-lag nonlinear model in addition to the over-dispersed generalized additive model to investigate the association between daily ambient temperature and renal colic incidence after controlling for seasonality, humidity, public holidays, and day of the week. We identified 3158 EADs for renal colic during the study period. This exposure-response curve was almost flat when the temperature was low and moderate and elevated when the temperature increased over 21 °C. For heat-related effects, the significant risk occurred on the concurrent day and diminished until lag day 7. The cumulative relative risk of hot temperatures (90th percentile) and extremely hot temperatures (99th percentile) over lag days 0-7 was 1.92 (95 % confidence interval, 1.21, 3.05) and 2.45 (95 % confidence interval, 1.50, 3.99) compared with the reference temperature of 21 °C. This time-series analysis in Guangzhou, China, suggested a nonlinear and lagged association between high outdoor temperatures and daily EADs for renal colic. Our findings might have important public health significance to prevent renal colic.

    Full Text Available Background. Renal colic is a medical emergency due to the rapid onset and devastating nature of its pain. Opioids and nonsteroidal anti-inflammatory drugs (NSAIDs are both used as first-line choices in its management. Aim. This study aimed to compare the efficacy and safety of opioids and NSAIDs in the management of acute renal colic. Methods. One hundred and fifty-eight patients were divided into two groups (n=79 and received either 10 mg morphine or 100 mg indomethacin suppositories. The severity of pain was measured using verbal numeric rating scale at baseline and 20, 40, 60, and 90 minutes after the administration of analgesics. Drug side effects as well as patients’ vital signs were also recorded. Results. The mean decrease in the pain score during the first 20 minutes was significantly higher among those who received morphine suppository. However, no significant difference was observed between the two groups regarding the mean decrease in pain score during the first 40, 60, and 90 minutes after the admission. Prevalence of drug side effects or changes in the vital signs was not significantly different between the two groups. Conclusions. Morphine suppositories seem to be more efficient in achieving rapid pain relief comparing to indomethacin.

    To determine whether magnetic resonance urography (MRU), obtained before helical computed tomography (CT) in patients with acute renal colic, can help delimit the obstructed area to be subsequently examined by a targeted CT scan, thus reducing the dose of radiation. Patients (51) with symptoms of acute renal colic underwent MRU and a total urinary tract helical CT. CT images from the 5 cm below the level of ureteral obstruction as demonstrated by MRU were selected out. Combined interpretation of MRU and selected CT images constituted protocol A. Protocol B consisted of the entire unenhanced helical CT of the urinary tract. The two protocols were compared regarding the following points: 1) sensitivity in diagnosing the presence of obstructing urinary stones, and 2) the delivered radiation dose. Protocol A and protocol B had, respectively, 98% and 100% sensitivity in demonstrating ureteral stone as a cause of renal colic. Estimated average dose calculated from phantom study was 0.52 mSv for protocol A and 2.83 mSv for protocol B. Therefore, the effective radiation dose was 5.4 times lower in protocol A compared to protocol B. Combined MRU and short helical CT has a high sensitivity in detecting ureteral calculi with a reduced radiation dose. Copyright 2004 Wiley-Liss, Inc.

    The purpose of our study was to compare a low-dose abdominal CT protocol, delivering a dose of radiation close to the dose delivered by abdominal radiography, with standard-dose unenhanced CT in patients with suspected renal colic. One hundred twenty-five patients (87 men, 38 women; mean age, 45 years) who were admitted with suspected renal colic underwent both abdominal low-dose CT (30 mAs) and standard-dose CT (180 mAs). Low-dose CT and standard-dose CT were independently reviewed, in a delayed fashion, by two radiologists for the characterization of renal and ureteral calculi (location, size) and for indirect signs of renal colic (renal enlargement, pyeloureteral dilatation, periureteral or renal stranding). Results reported for low-dose CT, with regard to the patients' body mass indexes (BMIs), were compared with those obtained with standard-dose CT (reference standard). The presence of non-urinary tract-related disorders was also assessed. Informed consent was obtained from all patients. In patients with a BMI 3 mm. Low-dose CT was 100% sensitive and specific for depicting non-urinary tract-related disorders (n = 6). Low-dose CT achieves sensitivities and specificities close to those of standard-dose CT in assessing the diagnosis of renal colic, depicting ureteral calculi > 3 mm in patients with a BMI < 30, and correctly identifying alternative diagnoses.

    Full Text Available Urolithiasis affects an estimated 5% of the population and the lifetime risk of passing a stone in the urinary tract is estimated to be 8-10%. Urinary calculus formation is highly variable and while certain risk factors such as age, gender, seasonality, anatomic abnormality, and metabolic diseases have been identified, not much is known regarding the association of environmental factors such as lunar phases on renal colic. We conducted a retrospective study to test the hypothesis that full moon phase is an environmental factor associated for increased emergency department (ED visits for renal colic due to ureteral calculus.We analyzed 559 renal colic diagnoses by the ED at the University of Nebraska Medical Center in a 24-month period and compared them with corresponding lunar phases as well as supermoon events. The lunar phases were defined as full moon ± two days, new moon ± two days, and the days in-between as normal days according to the lunar calendar. Supermoon event dates were obtained from NASA.90 cases (16.1% were diagnosed during full moon phase, 89 cases (15.9% were diagnosed during new moon phase, and 380 cases (68.0% were diagnosed during normal days. The incidence of renal colic showed no statistically significant association with lunar phases or supermoon events.In this retrospective longitudinal study with adequate power, neither full moon phase nor supermoon event exhibited an association with increased renal colic diagnoses due to ureteral calculus by the ED at the University of Nebraska Medical Center.

    Full Text Available Although the application of ureteroscopy in the treatment of ureteral calculi during pregnancy has been on the rise, for persistent renal colic patients without ultrasound-detected ureteral calculi, it may represent a clinical dilemma due to the potential risks for both mother and fetus.The aim of the present study is to present our experience with the application of the ureteroscope in the emergency treatment of persistent renal colic patients during pregnancy.From March 2009 to September 2014, a total of 117 pregnant women who received ureteroscopy for persistent renal colic were retrospectively analyzed. Patients were divided into three groups according to duration of the persistent renal colic: Group A (within 12 hours; 24 cases; Group B (12 to 24 hours; 76 cases; and Group C (more than 24 hours; 17 cases. The stone-free rate, complications, and other qualitative data were analyzed.Of the 117 patients, 31 patients who were found not to have renal or ureteral calculi received ureteroscopic double-J (DJ stent insertion, whereas 86 patients who were found with ureteral calculi received ureteroscopic lithotripsy (URSL and DJ stent insertion. Among them, 24 patients (27.9% were found with ureteral calculi by ureteroscopy rather than ultrasound. In addition, 73 patients (84.9% had complete fragmentation of calculi; 12 patients (10.3% had a threatened abortion (the rates of threatened abortion in Groups A, B and C were 8.3% vs. 6.5% vs. 29.4%; Group C compared with Groups A and B, p<0.05, and one patient (1.2% had urosepsis (in Group C. However, these complications were cured with conservative treatment, without postpartum infant and maternal complications.For pregnant patients with persistent renal colic/ureteral calculi and hydronephrosis, ureteroscopic DJ stent insertion and URSL are effective and safe options when conservative treatment fails, even if no urinary calculi were found by ultrasound. At the same time, for patients with persistent

    Full Text Available Introduction: The main purpose of emergency department (ED management for renal colic  is prompt pain relief. The present study aimed to compare the analgesic effects of intravenus (IV ketofol with morphine in management of ketorolac persistent renal colic. Methods: This study is a single blind randomized, clinical trial, on patients who were presented to ED with renal colic, whose pain was resistant to 30 mg IV ketorolac. The patients were randomly assigned to either IV morphine (0.1 mg/kg or IV ketofol (0.75 mg/kg propofol and 0.75 mg/kg and the measures of treatment efficacy were compared between the groups after 5 and 10 minutes. Results: 90 patients with mean age of 38.01 ± 9.78 years were randomly divided into 2 groups of 45 (66.7% male. Treatment failure rate was significantly lower in ketofol group after 5 (20% vs 62.2%, p < 0.001 and 10 minutes (11.1% vs 44.4%, p < 0.001. ARR and NNT for ketofol after 5 miutes were 42.22% (95% CI: 23.86 – 60.59 and 3 (95% CI: 1.7 - 4.2, respectively. After 10 minutes, these measures reached 33.33 (95% CI:16.16 – 50.51 and 4 (95% CI: 2.0 - 6.2, respectively. NNH and ARI for hallucination or agitation were 12 (95%CI: 5.8 - 174.2 and 8.89% (0.57 - 17.20, respectively. Conclusion: The results of the present study, showed the significant superiority of ketofol (NNT at 5 minute = 3 and NNT at 10 minute = 4  in ketorolac resistant renal colic pain management. However, its NNH of 12, could limit its routine application in ED for this purpose.

    Full Text Available Mostafa Yakoot,1 Amel Salem,2 Sameh Yousef,2 Sherine Helmy31Green Clinic and Research Center, 2Alexandria Helmy Medical Center, 3Pharco Corporation, Alexandria, EgyptBackground: Renal colic is typically characterized by the sudden onset of severe pain radiating from the flank to the groin and its acute management in emergency departments essentially aims at rapid pain relief. Spasmofen® is a brand of Amriya Pharmaceutical Industries in the form of rectal suppositories containing ketoprofen 100 mg and hyoscine butylbromide 10 mg. This combination is intended for the rapid relief of severe colicky pain in the renal system, hepatobiliary system, or gastrointestinal tract. This trial aims to compare a single-dose of Spasmofen rectal suppository to a single intravenous (IV ketorolac tromethamine 30 mg/2 mL dose in patients with acute renal colic.Methods: A total of 80 eligible consecutive patients presenting to the emergency departments of two medical centers with acute renal colic were included in the study. Eligible patients who signed the informed consent were randomly assigned into two treatment groups: an experimental group (Spasmofen group who received one Spasmofen rectal suppository plus an IV injection of 2 mL of normal saline solution; and a control group (ketorolac group who received one ketorolac 30 mg/2 mL ampoule IV plus one placebo suppository. Treatment success, defined as a change in the verbal rating score from severe or moderate pain to none or mild at 60 minutes after the dose, was compared between groups using the chi-square/Fisher's exact test. Percentage reductions in visual pain analog scale (VPAS scores at 15 and 60 minutes after the dose were compared between groups using the Z-test for proportions.Results: Successful treatment at 60 minutes occurred in 35 of 40 (87.5% of Spasmofen-treated patients and in 33 of 40 (82.5% of ketorolac-treated patients. The difference was not statistically significant by Fisher's exact test

    Sex-related differences occur in many areas of medicine. Emergency department (ED) studies have suggested differences in access to care, diagnostic imaging use, pain management, and intervention. We investigated sex-based differences in the care and outcomes for ED patients with acute renal colic. This was a multicenter population-based retrospective observational cohort study using administrative data and supplemented by structured chart review. All patients seen in Calgary Health Region EDs between January 1 and December 31, 2014, with an ED diagnosis of renal colic based on the following ICD-10 codes were eligible for inclusion: calculus of kidney (N200), calculus of ureter (N201), calculus of kidney with calculus of ureter (N202), hydronephrosis with renal and ureteral calculous obstruction (N132), unspecified renal colic (N23), and unspecified urinary calculus (N209). ED visit data and test results were accessed in the regional ED clinical database. Stone characteristics were captured from diagnostic imaging reports. Regional hospital databases were used to identify subsequent ED encounters, hospital admissions, and surgical procedures within 60 days. Outcomes were stratified by sex. The primary outcome, intended as a marker of overall effectiveness of ED care, was the unscheduled 7-day ED revisit rate among patients who were discharged home after their index ED visit. Secondary outcomes included ED pain management as reflected by administration of narcotics or intravenous nonsteroidals, the performance of advanced imaging-either ultrasound (US) or computed tomography (CT), and the proportion of patients who required hospitalization or surgical intervention within 60 days. From January 1 to December 31, 2014, a total of 3,104 eligible patients were studied: 1,111 women (35.8%) and 1,993 men (64.2%). Baseline characteristics, access times, analgesic use, and admission rates were similar in both groups. Men were more likely to have CT (68.9% vs. 58

    2015-03-01

    Full Text Available Introduction: In the United States there is debate regarding the appropriate first test for new-onset renal colic, with non-contrast helical computed tomography (CT receiving the highest ratings from both Agency for Healthcare Research and Quality and the American Urological Association. This is based not only on its accuracy for the diagnosis of renal colic, but also its ability to diagnose other surgical emergencies, which have been thought to occur in 10-15% of patients with suspected renal colic, based on previous studies. In younger patients, it may be reasonable to attempt to avoid immediate CT if concern for dangerous alternative diagnosis is low, based on the risks of radiation from CTs, and particularly in light of evidence that patients with renal colic have a very high likelihood of having multiple CTs in their lifetimes. The objective is to determine the proportion of patients with a dangerous alternative diagnosis in adult patients age 50 and under presenting with uncomplicated (non-infected suspected renal colic, and also to determine what proportion of these patients undergo emergent urologic intervention. Methods: Retrospective chart review of 12 months of patients age 18-50 presenting with “flank pain,” excluding patients with end stage renal disease, urinary tract infection, pregnancy and trauma. Dangerous alternative diagnosis was determined by CT. Results: Two hundred and ninety-one patients met inclusion criteria. One hundred and fifteen patients had renal protocol CTs, and zero alternative emergent or urgent diagnoses were identified (one-sided 95% CI [0-2.7%]. Of the 291 encounters, there were 7 urologic procedures performed upon first admission (2.4%, 95% CI [1.0-4.9%]. The prevalence of kidney stone by final diagnosis was 58.8%. Conclusion: This small sample suggests that in younger patients with uncomplicated renal colic, the benefit of immediate CT for suspected renal colic should be questioned. Further studies are

    Full Text Available Abstract Background Despite the fact that numerous medications have been introduced to treat renal colic, none has been proven to relieve the pain rapidly and thoroughly. In this study, we aimed at comparing the effects of intravenous lidocaine versus intravenous morphine in patients suffering from renal colic. Methods In a prospective randomized double-blind clinical trial performed in the emergency department of Imam Reza educational hospital of Tabriz, Iran, we studied 240 patients, 18–65 years old, who were referred due to renal colic. Patients were divided into two groups. In group I (120 people single-dose intravenous lidocaine (1.5 mg/kg was administered and in group II (120 people single-dose intravenous morphine (0.1 mg/kg was administered slowly. Visual Analogue Pain Scale (VAS was recorded while admission, 5, 10, 15 and 30 minutes after injection. Statistical data and results were studied using descriptive statistics as percentage and Mean ± SD. To compare the response to treatment, Mann–Whitney U-test was used in two groups. Consequently, the data were analyzed using the SPSS16 software. Results Pain score measured in two groups five minutes after the injection of lidocaine and morphine were 65 % and 53 % respectively (95% CI 0.60 - 0.69, CI 0.48 – 0.57, p = 0.0002.108 (90 % patients (95 % CI 0.84 – 0.95 from group I and 84 (70% patients (95 % CI 0.62 - 0.78 from group II responded appropriately at the end of the complete treatment. The difference was statistically significant (p = 0.0001. Conclusions Changing the smooth muscle tone and reducing the transmission of afferent sensory pathways, lidocaine causes a significant reduction in pain.

    To determine an optimal invasive intervention for renal colic patients during pregnancy after conservative treatments have been found to be unhelpful. Among the available invasive interventions, we investigated the reliability of a ureteral stent insertion, which is considered the least invasive intervention during pregnancy. Between June 2006 and February 2015, a total of 826 pregnant patients came to the emergency room or urology outpatient department, and 39 of these patients had renal colic. The mean patient age was 30.49 years. In this retrospective cohort study, the charts of the patients were reviewed to collect data that included age, symptoms, the lateralities and locations of urolithiasis, trimester, pain following treatment and pregnancy complications. Based on ultrasonography diagnoses, 13 patients had urolithiasis, and 13 patients had hydronephrosis without definite echogenicity of the ureteral calculi. Conservative treatments were successful in 25 patients. Among these treatments, antibiotics were used in 15 patients, and the remaining patients received only hydration and analgesics without antibiotics. Several urological interventions were required in 14 patients. The most common intervention was ureteral stent insertion, which was performed in 13 patients to treat hydronephrosis or urolithiasis. The patients' pain was relieved following these interventions. Only one patient received percutaneous nephrostomy due to pyonephrosis. No pregnancy complications were noted. Ureteral stent insertion is regarded as a reliable and stable first-line urological intervention for pregnant patients with renal colic following conservative treatments. Ureteral stent insertion has been found to be equally effective and safe as percutaneous nephrostomy, which is associated with complications that include bleeding and dislocation, and the inconvenience of using external drainage system.

    Various drugs have been used to relieve abdominal pain in patients with renal colic. Ketamine is a popular choice as an analgesic. To compare the effectiveness of intranasal (IN) ketamine versus intravenous (IV) morphine in reducing pain in patients with renal colic. A randomized double-blind controlled trial was performed in 53 patients with renal colic recruited from the emergency department (ED) in 2015. Finally, 40 patients were enrolled in this study. Patients in the ketamine group received IN ketamine 1 mg/kg and IV placebo while patients in the control group received IV morphine 0.1mg/kg and IN placebo. Our goal was to assess visual analogue scale (VAS) changes between the 2 groups. Patients' VAS scores were reported before and 5, 15, 30min after drug injection. Before drug administration, the mean±SD VAS score was 7.40±1.18 in the morphine group (group A) and 8.35±1.30 in the ketamine group (group B) (P-value=0.021). After adjustment by the appropriate analysis, the mean±SD VAS score in group (A) and (B) at 5min were (6.07±0.47 vs 6.87±0.47; mean difference -0.79, 95% confidence interval (CI) -1.48 to -1.04) (P-value=0.025), at 15 and 30min, the mean±SD VAS score in group (A) and (B) were (5.24±0.49 vs 5.60±0.49; mean difference -0.36, 95% CI -1.08 to 0.34) and (4.02±0.59 vs 4.17±0.59; mean difference -0.15, 95% CI -1.02 to 0.71) (P-value=0.304 and 0.719) respectively. IN ketamine may be effective in decreasing pain in renal colic. Copyright © 2016 Elsevier Inc. All rights reserved.

    To evaluate all possible risk factors that can cause impairment of overall renal function in patients with unilateral ureteral calculus and a normal contralateral kidney. This is a prospective study of 90 patients who presented to our institute complaining of renal colic secondary to unilateral ureteral calculus. All patients were evaluated with a thorough history, physical examination, and laboratory and radiological investigations including renal function testing, urine analysis, non-contrast computed topography, and radionucleotide scan. Patients were divided into two groups according to their calculated creatinine clearance using the Modification of Diet in Renal Disease (MDRD) formula. Group I (favorable group) had a creatinine clearance >60 ml/min, while group II (unfavorable group) had a creatinine clearance II included 36 patients (40 %). On univariate analysis, factors that were associated with overall renal function impairment were patients' age, urea-to-creatinine ratio (UCR), use of nonsteroidal anti-inflammatory drugs, stone location, and presence of obstruction. However, using binary logistic regression analysis, only patients' age, UCR, and presence of obstruction sustained statistical significance in association with renal function impairment. The study of factors that help explain the presence of renal impairment in patients with unilateral ureteral calculus is important in the clinical setting. Patients' age, urea-to-creatinine ratio, and degree of obstruction seem to be significantly associated with overall renal function impairment.

    An 11-year-old Andalusian stallion developed marked signs of colic associated with an acute small intestine obstruction. Exploratory laparotomy revealed a distal jejunum full-thickness wall induration and multiple small adherent intraluminal masses. Fifteen centimeters of jejunum, including the induration, and several intraluminal masses were resected. Histologic examination revealed an adenocarcinoma and multiple polypoid adenomas. The horse was discharged, and no complications were reported 12 months postoperatively. Colic was considered secondary to partial jejunal lumen obstruction by the adenocarcinoma. Adenocarcinoma recurrence or transformation from remaining adenomas into an adenocarcinoma is still a major risk.

    Hepatobiliary and pancreatic ascariasis occur due to migration of the round worm ascaris lumbricoides through the bile duct orifice finally reaching the common bile duct, main pancreatic duct, intrahepatic ducts or gallbladder. These resulted in acute epigastric and right hypochondriac region colicky pain. Ultrasound is the investigation of choice in hepatobiliary ascariasis. We present here sonographic images on four pediatric patients with acute biliary colic.

    Full Text Available We present the case of a young man with Klinefelter syndrome, who was admitted to our clinic with renal colic. Shortly after admittance, spontaneous decrease in pain has occurred. Ultrasound and intravenous contrast computed tomography were performed, which showed the evidence of urine extravasation at the level of left renal pelvis and a 4 mm stone in the lower third of the left ureter. The management with a double-J ureteric stent for three weeks was successful. Then, the stent was removed and computed tomography confirmed the absence of urine extravasation. We also analyze the literature related to this case and discuss the main mechanisms of collecting system rupture.

    Logistic regression is the most common statistical model for processing multivariate data in the medical literature. Artificial intelligence models like an artificial neural network (ANN) and genetic algorithm (GA) may also be useful to interpret medical data. The purpose of this study was to perform artificial intelligence models on a medical data sheet and compare to logistic regression. ANN, GA, and logistic regression analysis were carried out on a data sheet of a previously published article regarding patients presenting to an emergency department with flank pain suspicious for renal colic. The study population was composed of 227 patients: 176 patients had a diagnosis of urinary stone, while 51 ultimately had no calculus. The GA found two decision rules in predicting urinary stones. Rule 1 consisted of being male, pain not spreading to back, and no fever. In rule 2, pelvicaliceal dilatation on bedside ultrasonography replaced no fever. ANN, GA rule 1, GA rule 2, and logistic regression had a sensitivity of 94.9, 67.6, 56.8, and 95.5%, a specificity of 78.4, 76.47, 86.3, and 47.1%, a positive likelihood ratio of 4.4, 2.9, 4.1, and 1.8, and a negative likelihood ratio of 0.06, 0.42, 0.5, and 0.09, respectively. The area under the curve was found to be 0.867, 0.720, 0.715, and 0.713 for all applications, respectively. Data mining techniques such as ANN and GA can be used for predicting renal colic in emergency settings and to constitute clinical decision rules. They may be an alternative to conventional multivariate analysis applications used in biostatistics.

    Full Text Available Objective: To compare the analgesiceffects of Nitrous oxide and morphine sulfate in patients with acute renal colic due to urolithiasis. Methods: This was randomized clinical trial being performed in Imam Hossein hospital affiliated with Shahid Beheshti University of Medical Sciences during a 1-year period from May2013 to May2014. A total of number of 100 patients, with an age range of 20-50 years, who presented with renal colic secondary to urolithiasis confirmed by ultrasonography were randomly assigned to receive morphine sulfate injection (0.1 mg/kg with 100 mg diclofenac suppository (n=50 or Entonox exhalation (50% nitric oxide and 50% oxygenfor 30-minutes with 100 mg diclofenac suppository (n=50. Quantitative measurement was of pain was performed according to a visual analogue scale (VAS, before, 3, 5, 10 and 30-minute after the intervention. The pain severity and side effects were measured between two study groups. Results: The baseline characteristics of the patients in two study groups were comparable. The frequencies of pain persistence (at least 50% at 3-, 5-, 10- and 30-minute intervals in morphine sulfategroup were 96%, 80%, 50% and 8%, respectively; these frequencies in Entonex were 82%, 42%, 12% and 2%, respectively (p<0.001. Cox regression modeling showed that use of Entonox was the only effective agent in the success of treatment, compared to the use of morphine, i.e. use of Entonox increased the success of treatment up to 2.1 folds compared to the use of morphine (HR=2.1; 95% CI: 1.2-3.6; p=0.006. Conclusion: The results of the present study demonstrate that inhalation of Entonox is an effective and safe analgesic regimen for acute renal colic. It acts more rapidly and is more potent in relieving renal colic when compared to morphine sulfate.Entonox can be regarded as an appropriate alternative to analgesics like opioids in this ground.

    2010-07-01

    Acute ureteric colic is a common emergency, often dealt with by the emergency physician or general practitioner and referred on to the urologist. Unenhanced CT of the kidneys, ureters and bladder (CTKUB) is the 'gold standard' imaging investigation for establishing a diagnosis and guiding management. An appreciation of the CTKUB signs, which support or refute a diagnosis of ureteric colic, is highly valuable to the clinician when making a urological referral, and to the urologist, who must make appropriate management plans. All salient diagnostic and supportive features of ureteric colic are carefully illustrated, as are important radiological mimics, with the objectives of educating and informing the non-radiologist. Ready access to the picture archive and communication system (PACS) allows all specialists involved to interpret the radiological report with the benefit of images. A stone within the ureter may not always be readily apparent. Soft tissue rim sign around a calcific focus is an important indicator of a ureteric stone, whereas a comet tail sign suggests a phlebolith (a calcified venous thrombosis), a radiological mimic of a ureteric stone. Numerous secondary signs of ureteric obstruction may be present including hydronephrosis and perinephric stranding, and can help to confirm the diagnosis. The relative diagnostic weighting of signs is discussed, and a checklist is provided to assist with interpretation. Unexpected alternative radiological diagnoses are also illustrated, which may have significant management consequences necessitating specialist referral.

    The acute phase proteins (APP) serum amyloid A (SAA), haptoglobin, and fibrinogen are valuable blood biomarkers in equine inflammatory diseases, but knowledge of factors influencing their concentrations in blood and peritoneal fluid (PF) of horses with colic is needed. The objective of this study was to investigate the influence of demographics (age, sex, breed), disease process (simple obstruction, strangulating obstruction, inflammatory), disease location, disease duration, hypovolemia, and admission hospital on concentrations of APP, lactate and white blood cell counts (WBC) in horses with colic admitted to 2 referral hospitals. The study included 367 horses with colic admitted at 2 referral hospitals. Prospective multicenter observational study of clinical data, as well as blood and PF biomarkers. Associations between biomarker concentrations and clinical variables were analyzed using multivariate linear regression analysis. Increasing pre-admission duration of colic was associated with increased concentrations of APP in blood and PF. Blood concentrations of SAA and fibrinogen were associated with disease process (inflammatory, strangulations, simple obstructions) in more colic duration groups (5-12 and >24 hours) than any of the other biomarkers. No relevant associations between demographic factors, hospital, or hydration status and the measured biomarkers were found. In horses with colic, concentrations of APP are associated mainly with disease process and duration of colic and may thus be used for assessment of disease independently of demographic or geographic factors. Serum amyloid A may be a diagnostic marker for use in colic differential diagnosis, but further evaluation is needed. Copyright © 2015 by the American College of Veterinary Internal Medicine.

  10. 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.

    In recent years, noncontrast helical computed tomography has modified the imaging techniques employed in the management of patients who arrive in the emergency service presenting signs of renal colic. Based on the literature and our own experience with 140 patients who complained of pain suggestive of a colic probably due to stone disease, we review the radiological features of this entity and discuss the utility of the technique in confirming the diagnosis, predicting the clinical course and detecting other diseases that present with identical symptomatology.

    2009-09-01

    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.

    Aim: To establish whether non-contrast enhanced computed tomography (NCCT) renders the kidneys-ureters-bladder (KUB) radiograph redundant as the initial imaging investigation for suspected acute ureteric colic. Materials and methods: The imaging investigations for 120 patients consecutively admitted to an emergency department-led clinical decisions unit (CDU) with suspected acute ureteric colic were retrospectively reviewed. A multidisciplinary meeting reviewed the findings and recommended that KUB radiographs should not be routinely performed prior to NCCT. Prospective assessment of 116 consecutive patients admitted over a comparable period was then undertaken. Results: In the retrospective group, 61 (50.8%) patients had calculi to account for symptoms (positive NCCT) and 59 (49.2%) patients did not have stone disease (negative NCCT). Ninety (75%) patients had a KUB radiograph prior to NCCT. However, in 46 (38% of total) of these patients the NCCT was negative for stones, and therefore, they had been subjected to an unnecessary radiographic examination. These results prompted a change in practice. In the subsequent and prospectively studied group, preliminary KUB radiographs were performed in only 6% of the patients, with no significant change in the positive NCCT rate (50.8 versus 51.7%) or the total number of examinations performed (120 versus 116). Conclusion: NCCT should be the initial imaging examination for acute ureteric colic. Up to 50% of patients with clinical suspicion do not have stone disease, and therefore, preliminary KUB radiographs with attendant radiation and cost implications are unjustified. Preliminary KUB radiographs can be omitted from the imaging pathway with no resultant indication creep or increase in demand for NCCT examinations.

Medical records of patients with diagnosis of acute RI, established by contrast enhanced computed tomography (CT and at least 1 year follow-up data, who were hospitalized in our clinic between 1998 and 2012 were retrospectively reviewed; including descriptive data, clinical signs and symptoms, etiologic factors, laboratory findings, and prescribed treatments. Patients with solitary infarct were treated with acetylsalicylic acid (ASA only, whereas patients with atrial fibrillation (AF or multiple or global infarct were treated with anticoagulants. Estimated Glomerular Filtration Rate (eGFR referring to renal functions was determined by the Modification of Diet in Renal Disease (MDRD formula. Twenty-seven renal units of 23 patients with acute RI were identified. The mean age was 59.7 ± 15.7 years. Fourteen patients (60.8% with RI had atrial fibrillation (AF as an etiologic factor of which four had concomitant mesenteric ischemia at diagnosis. At presentation, 20 patients (86.9% had elevated serum lactate dehydrogenase (LDH, 18 patients (78.2% had leukocytosis, and 16 patients (69.5% had microscopic hematuria. Two patients with concomitant mesenteric ischemia and AF passed away during follow up. Mean eGFR was 70.8 ± 23.2 mL/min/1.73 m2 at admission and increased to 82.3 ± 23.4 mL/min/1.73 m2 at 1 year follow up. RI should be considered in patients with persistent flank or abdominal pain, particularly if they are at high risk of thromboembolism. Antiplatelet and/or anticoagulant drugs are both effective treatment options according to the amplitude of the infarct for preserving kidney functions.

    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

    management of patients with nephritic colic in a referral hospital, their monitoring and the incidence of alternative diagnoses. Methods. This is a retrospective review of 182 randomly selected patients who presented a clinical diagnosis compatible with nephritic colic in a referral hospital. In these cases initial treatment, monitoring and alternative diagnoses have been evaluated. Results. Fifty-five point four percent of the patients were male, the mean age was 47.7 years and 40% of the cases were in spring. Urinalysis was carried out in every patient (62.7% dipstick and 72% urinary sediment; they were pathological in over 70%. In 26.4% of cases renal function deteriorated, always transiently. Abdominal radiography (81.9% was the most frequently diagnostic test performed, followed by ultrasound (25.8%. Treatment included a serum therapy in 31.3%; metamizol (61% was the most commonly used analgesic followed by ketorolac (44.5%. More than one non-steroidal anti-inflammatory was used by 46.2%. Hospital admission was required by 24 patients, and 5 of them needed emergency surgery. Twenty-four point one percent of patients had relapses during the next six months. Forty-one point six percent were referred to urology discharge on from the emergency room. Eighteen point one percent of patients had alternative diagnoses; acute pyelonephritis was the most frequent of these (55%. Conclusions. In our work we found a significant variation in the diagnostic and therapeutic management of these patients. The use of clinical guidelines could help us to unify the management of patients with nephritic colic, both in the emergency room and on discharge. Due to the high prevalence of alternative diagnoses, we have to systematically exclude more serious diseases.

    To evaluate a low-dose abdominal computed tomography (LDCT) protocol, delivering a radiation dose close to that delivered by an abdominal plain film (APF), in patients with a clinical suspicion of renal colic. A total of 139 patients for whom an APF was requested for suspicion of renal colic were randomized into two groups. The patients in group 1 (n = 68) underwent an admission LDCT scan delivering a 2.1-mSv radiation dose to women and 1.6 mSv to men, instead of the APF. Patients in group 2 (n = 71) underwent an APF. Clinical and radiologic follow-up data were obtained for each patient. The number of additional abdominal ultrasound and CT scans performed to reach a confident final diagnosis and determine the proper treatment was compared between the two groups. A mean effective radiation dose was obtained in each group. Of the 68 patients in group 1 (LDCT), 10 (15%) underwent ultrasonography, 9 (13%) conventional abdominal CT, and 2 (3%) both. In group 2 (APF), the corresponding percentages were 27% (19 of 71), 28% (20 of 71), and 23% (16 of 71). Of the 68 patients in group 1, 47 (69%) did not require any additional examinations compared with 16 (23%) of the 71 patients in group 2 (P < 0.0001). The mean effective dose was 3.5 and 6.9 mSv in groups 1 and 2, respectively (P < 0.0001). In patients with suspicion of renal colic, replacing the admission APF with our LDCT protocol will significantly reduce the need for additional CT or ultrasonography. Also, our LDCT protocol decreases by almost 50% the mean radiation dose per patient.

  1. Renal tubule cell repair following acute renal injury.

    Science.gov (United States)

    Humes, H D; Lake, E W; Liu, S

    1995-01-01

    Experimental data suggests the recovery of renal function after ischemic or nephrotoxic acute renal failure is due to a replicative repair process dependent upon predominantly paracrine release of growth factors. These growth factors promote renal proximal tubule cell proliferation and a differentiation phase dependent on the interaction between tubule cells and basement membrane. These insights identify the molecular basis of renal repair and ischemic and nephrotoxic acute renal failure, and may lead to potential therapeutic modalities that accelerate renal repair and lessen the morbidity and mortality associated with these renal disease processes. In this regard, there is a prominent vasoconstrictor response of the renal vasculature during the postischemic period of developing acute renal failure. The intravenous administration of pharmacologic doses of atrial natriuretic factor (ANF) in the postischemic period have proven efficacious by altering renal vascular resistance, so that renal blood flow and glomerular filtration rate improve. ANF also appears to protect renal tubular epithelial integrity and holds significant promise as a therapeutic agent in acute renal failure. Of equal or greater promise are the therapeutic interventions targeting the proliferative reparative zone during the postischemic period. The exogenous administration of epidermal growth factor or insulin-like growth factor-1 in the postischemic period have effectively decreased the degree of renal insufficiency as measured by the peak serum creatinine and has hastened renal recovery as measured by the duration of time required to return the baseline serum creatinine values. A similarly efficacious role for hepatocyte growth factor has also been recently demonstrated.

    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.

    Four renal transplant patients on immunosuppressive therapy who presented with acute myeloid leukaemia are described. In two cases, azathioprine may have played an important role as a cofactor in leukaemogenesis. In a third case, the alkylating agent cyclophosphamide may have contributed. All patients were treated for leukaemia with full doses of cytotoxic chemotherapy and, in each case, a functioning renal allograft was preserved throughout the treatment despite attenuation of immunosuppressive therapy. Three patients achieved complete remission. Of the three, one is surviving at 2 years and two expired during the pancytopenic phase of their treatment with no active leukaemia present, and with intact renal function. As increasing expertise in the field of organ transplantation allows patients to survive longer, such patients' exposure to immunosuppressive and potentially leukaemogenic drugs is prolonged. The risk of secondary neoplasia has been previously documented in this population. Two of the four cases reported here suffered from polycystic kidney disease as their underlying condition. While this report suggests that the leukaemias are related to renal transplantation, we cannot rule out an association with the underlying disease which led to the transplant. This report further suggests that the leukaemia that develops in such patients may respond to standard therapy, and that such treatment does not compromise the transplanted kidney.

    To report our experience with magnetic resonance urography (MRU) in pregnant women suspected of having obstructing upper tract calculi. The diagnosis of an upper tract calculus in the pregnant woman can be challenging. Recent evidence suggests that MRU can be used to effectively evaluate renal colic. From 2008-2011, 9 pregnant women were referred for evaluation of suspected renal colic caused by an obstructing upper tract stone. All patients underwent MRU with a half Fourier single-shot turbo spin-echo (HASTE) protocol. Medical records and imaging studies were reviewed for demographic and clinical data as well as outcome measures. The mean age of the subjects was 25 years (range 20-34); average gestational age of the fetus was 23 weeks (range 9-36). In all cases, a renal ultrasound was the initial imaging study obtained, with nondiagnostic findings. HASTE MRU detected 4 ureteral stones and 4 cases of physiological hydronephrosis of pregnancy. In one case, interpretation of the MRU was limited as a result of patient motion. Of the patients with obstructing stones, 1 required endourologic management during her pregnancy and 3 were followed conservatively. No adverse events related to MRU occurred. HASTE MRU is an informative imaging study for pregnant women with suspected upper tract stone disease. Information gathered from this study augments that gained from alternative modalities, and aids in medical decision-making. The lack of ionizing radiation exposure, coupled with the capture of detailed anatomic imaging, makes HASTE MRU a particularly useful study in this setting. Copyright © 2012 Elsevier Inc.

    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.

  7. Infantile colic

    Full Text Available Infantile colic is one of the most common functional gastrointestinal disorders in infants, usually occurring between 2 weeks to 4 months of age. According to the definition, infantile colic is characterised by episodes of inconsolable crying, generally observed in the evening. Although these symptoms usually resolve spontaneously in the first six months of life, they often cause parental anxiety, leading to repeated medical appointments in search for help. Despite 40 years of research, the causes of this disorder are still unclear; hypersensitivity to cow’s milk protein, lactose intolerance, impaired gut microbiota, immaturity of the nervous system, the negative impact of tobacco smoke, inappropriate childcare techniques and psychosocial factors are believed to be involved in the pathogenesis. The treatment involves behavioural methods, i.e. reducing infant exposure to external stimuli. Breastfeeding mothers are advised to eliminate caffeine and hot spices from their diet and, in some cases, switch to a dairy-free diet. For formula-fed infants, it is recommended to use hydrolysates with a high degree of hydrolysis. Simethicone is commonly used in the pharmacological treatment as it reduces the surface tension of intestinal gases, enabling their easier elimination. The Rome III Diagnostic Criteria recommend to appropriately continue any method if considered effective by the parents, provided that there are no harmful consequences.

    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.

    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.

  11. Acute renal dysfunction in liver diseases

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Renal dysfunction is common in liver diseases, either as part of multiorgan involvement in acute illness or secondary to advanced liver disease. The presence of renal impairment in both groups is a poor prognostic indicator. Renal failure is often multifactorial and can present as pre-renal or intrinsic renal dysfunction. Obstructive or post renal dysfunction only rarely complicates liver disease. Hepatorenal syndrome (MRS) is a unique form of renal failure associated with advanced liver disease or cirrhosis, and is characterized by functional renal impairment without significant changes in renal histology. Irrespective of the type of renal failure, renal hypoperfusion is the central pathogenetic mechanism, due either to reduced perfusion pressure or increased renal vascular resistance. Volume expansion, avoidance of precipitating factors and treatment of underlying liver disease constitute the mainstay of therapy to prevent and reverse renal impairment. Splanchnic vasoconstrictor agents, such as terlipressin, along with volume expansion, and early placement of transjugular intrahepatic portosystemic shunt (TIPS) may be effective in improving renal function in HRS. Continuous renal replacement therapy (CRRT) and molecular absorbent recirculating system (MARS) in selected patients may be life saving while awaiting liver transplantation.

    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.

  13. 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.

    The thrombotic occlusion of one renal artery may become completely asymptomatic, due to the functionality of the contralateral kidney. However, in rare circumstances, such is the case of individuals with a solitary kidney, a situation of anuria and acute renal failure may constitute the main presentation of the condition. The authors report the clinical case of a 43 year old male patient, with the previous diagnosis of an infrarenal aortic occlusion and a single left kidney, who developed a thrombotic occlusion of the renal artery, with anuria and acute renal failure. The patient underwent an emergency revascularization procedure, consisting in the implantation of a prosthetic bypass graft from the superceliac aorta to the renal artery, with immediate recovery of the diuresis and renal function. Seventeen months later as a consequence of an anastomotic hyperplasia, an occlusion of the bypass graft occurred, again with anuria and acute renal failure. The patient was reoperated on and due to the inadequacy of both saphenous veins to be used as the material of choice for the revascularization procedure, a redundant segment of the left colic artery (Riolan's arcade) was removed and used as an interposition graft, from the middle colic artery to the renal artery, followed by an immediate restoration of diuresis and renal function. The singular and recurrent character of this clinical condition and the utilization of an original, eventually unique and well succeeded revascularization procedure, prompted its presentation and divulgation.

    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.

    The incidence of nephrolithiasis is rising worldwide, especially in women and with increasing age. Incidence and prevalence of kidney stones are affected by genetic, nutritional, and environmental factors. The aim of this study is to investigate the link between various meteorological factors (independent variables) and the daily number of visits to the Emergency Department (ED of the S. Croce and Carle Hospital of Cuneo for renal colic (RC) and urinary stones (UC) as the dependent variable over the years 2007-2010. The Poisson generalized regression models (PGAMs) have been used in different progressive ways. The results of PGAMs (stage 1) adjusted for seasonal and calendar factors confirmed a significant correlation ( p 1), with a first peak after 5 days (lag ranges 0-1, 0-3, and 0-5) and a second weak peak observed along the 5-15 lag range days. The estimated RR for females was significant, mainly in the second and fourth age group considered (19-44 and >65 years): RR for total ED visits 1.27, confidence interval (CI) 1.11-1.46 (lag 0-5 days); RR 1.42, CI 1.01-2.01 (lag 0-10 days); and RR 1.35, CI 1.09-1.68 (lag 0-15 days). The research also indicated a moderate involvement of the thermal factor in the onset of RC caused by UC, exclusively in the female sex. Further studies will be necessary to confirm these results.

  19. Growth factors and acute renal failure.

    Hirschberg, R; Ding, H

    1998-03-01

    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.

    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.

    1983-03-01

    To evaluate the effect of graft irradiation in the treatment of acute rejection of renal transplants, a randomized study was conducted from 1978 to 1981. Patients with acute rejection were given standard medical management in the form of intravenous methylprednisolone, and were chosen randomly to receive either graft irradiation (175 rads every other day, to a total of 525 rads) or simulated (sham) irradiation. Eighty-three rejections occurring in 64 grafts were randomized to the protocol. Rejection reversal was recorded in 84.5% of control grafts and 75% of the irradiated grafts. Recurrent rejections were more frequent and graft survival was significantly lower in the irradiated group (22%) than in the control group (54%). Graft irradiation does not appear to be beneficial in the treatment of acute rejection of renal transplants when used in conjunction with high-dose steroids.

    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.

  13. Acute renal failure due to rhabdomyolyisis

    Directory of Open Access Journals (Sweden)

    Nieto-Ríos, John Fredy

    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.

    In pediatric intensive care unit, the available modalities of acute renal replacement therapy include intermittent hemodialysis, peritoneal dialysis and continuous renal replacement therapies. No prospective studies have evaluated to date the effect of dialysis modality on the outcomes of children. The decision about dialysis modality should therefore be based on local expertise, resources available, and the patient's clinical status. Poor hemodynamic tolerance of intermittent hemodialysis is a common problem in critically ill patients. Moreover, many pediatric intensive care units are not equipped with dedicated water circuit. Peritoneal dialysis, a simple and inexpensive alternative, is the most widely available form of acute renal replacement therapy. However, its efficacy may be limited in critically ill patients. The use of continuous renal replacement therapy permits usually to reach a greater estimated dialysis dose, a better control of fluid balance, and additionally, to provide adequate nutrition.

    1995-10-01

    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.

  17. [Extracorporeal renal replacement therapies in acute renal failure].

    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.

    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.

    The aims of this study were to identify arteriographic manifestations of acute renal hemorrhage and to evaluate the efficacy of emergency embolization. Emergency renal artery angiography was performed on 83 patients with acute renal hemorrhage. As soon as bleeding arteries were identified, emergency embolization was performed using gelatin sponge, polyvinyl alcohol particles, and coils. The arteriographic presentation and the effect of the treatment for acute renal hemorrhage were analyzed retrospectively. Contrast extravasation was observed in 41 patients. Renal arteriovenous fistulas were found in 12 of the 41 patients. In all, 8 other patients had a renal pseudoaneurysm, 5 had pseudoaneurysm rupture complicated by a renal arteriovenous fistula, and 1 had pseudoaneurysm rupture complicated by a renal artery-calyceal fistula. Another 16 patients had tumor vasculature seen on arteriography. Before the procedure, 35 patients underwent renal artery computed tomography angiography (CTA). Following emergency embolization, complete hemostasis was achieved in 80 patients, although persistent hematuria was present in 3 renal trauma patients and 1 patient who had undergone percutaneous nephrolithotomy (justifying surgical removal of the ipsilateral kidney in this patient). Two-year follow-up revealed an overall effective rate of 95.18 % (79/83) for emergency embolization. There were no serious complications. Emergency embolization is a safe, effective, minimally invasive treatment for renal hemorrhage. Because of the diversified arteriographic presentation of acute renal hemorrhage, proper selection of the embolic agent is a key to successful hemostasis. Preoperative renal CTA plays an important role in diagnosing and localizing the bleeding artery.

    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

    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.

    Acute renal infarction presents in a similar clinical picture to that of a renal stone. We report a 55-year-old Saudi female, known to have atrial fibrillation secondary to mitral stenosis due to rheumatic heart disease. She presented with a two day history of right flank pain that was treated initially as a renal stone. Further investigations confirmed her as a case of renal infarction. Renal infarction is under-diagnosed because the similarity of its presentation to renal stone. Renal infarction should be considered in the differential diagnosis of loin pain, particularly in a patient with atrial fibrillation.

    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.

    Introduction Non-contrast helical CT (NHCT) became the procedure of choice for investigating Emergency Department (ED) patients presenting with suspected renal colic at Beaumont Hospital, Dublin, in 2008. The impact of NHCT on waiting times and patient management was compared with intravenous pyelography (IVP). Methods A retrospective, comparative cohort analysis of 95 patients who had IVP and 109 patients who had NHCT was performed. Length of ED stay from time of scan ordering to referral or discharge was analysed relative to time of day and scan result. Results Patients having NHCT who attended between 00:00-08:00 h, had a twofold longer length of stay than those who had IVP between the same hours (median 7.07 h vs 3.03 h, p=0.0294). The length of ED stay for patients attending between 08:00 and 24:00 h was similar in both groups. The presence of urolithiasis did not impact on length of stay. A significant alternate\\/incidental diagnosis was reported in 28 patients having NHCT, of which 12 were cancerous growths. Conclusion NHCT allows for the detection of incidental\\/alternate diagnoses that may not be otherwise detected in patients with renal colic. Compared to IVP, NHCT has not impacted positively on the speed of patient processing in the ED under study. For patients presenting after midnight, it is associated with over a twofold longer length of stay from the time of scan ordering to referral or discharge. This leads to prolonged patient stays in the ED, and as such contributes to overcrowding.

    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 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.

    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 Acute bilateral renal cortical necrosis following acute pancreatitis is extremely rare condition. Among all cases of acute renal failure, the incidence of renal cortical necrosis was 3.8% in one of the study in North India. Till date, only eight cases of bilateral cortical necrosis following acute pancreatitis were reported in the literature. We report a case of a 27-year-old male patient with abdominal pain, nausea and vomiting since 2 days duration and anuria since 24 h. Serum amylase and lipase were raised, and elevated serum creatinine was noted on admission. Contrast-enhanced computed tomography scan of the abdomen revealed changes of acute pancreatitis with hypoenhancement of renal cortex compared to medulla on both sides (reverse rim sign-stronger enhancement of the renal medulla compared to cortex, suggest an acute renal cortical necrosis.

    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

    2007-01-01

    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.

    2013-04-01

    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.

    2011-01-01

    Full Text Available The aim of this study was to find an accurate, easily available and safe imaging modality as an alternative to intravenous urography for the diagnosis of acute urinary obstruction. This retrospective study included 332 patients, who underwent both excretory urography (EU preceeded by plain radiograph as well as ultrasonography for evaluation of acute flank pain. There were 198 male and 134 female patients. The presence or absence of urinary stones, level of obstruction, excretion delay on EU and dilated excretory system on either or both techniques were recorded. The sensitivity, specificity, predictive values, and accuracy for plain radiograph, ultrasonography, and for both modalities together were measured considering EU as a standard reference. The sensitivity and specificity of combined plain radiograph and ultrasound were 97% and 67%, respectively, with positive and negative predictive values and accuracy rates of 92%, 99%, and 97%, respectively. Our study suggests that the combination of plain radiograph and ultrasonography yields a high sensitivity, negative predictive value, and accuracy in depiction of urinary stones. Thus, EU need not be used as a routine diagnostic procedure in patients with acute obstructive uropathy.

    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.

    Full Text Available Background. Several factors are implicated in renal stone formation and peak incidence of renal colic admissions to emergency departments (ED. Little is known about the influence of potential environmental triggers such as lunar gravitational forces. We conducted a retrospective study to test the hypothesis that the incidence of symptomatic renal colics increases at the time of the full and new moon because of increased lunar gravitational forces. Methods. We analysed 1500 patients who attended our ED between 2000 and 2010 because of nephrolithiasis-induced renal colic. The lunar phases were defined as full moon ± 1 day, new moon ± 1 day, and the days in-between as “normal” days. Results. During this 11-year period, 156 cases of acute nephrolithiasis were diagnosed at the time of a full moon and 146 at the time of a new moon (mean of 0.4 per day for both. 1198 cases were diagnosed on “normal” days (mean 0.4 per day. The incidence of nephrolithiasis in peak and other lunar gravitational phases, the circannual variation and the gender-specific analysis showed no statistically significant differences. Conclusion. In this adequate powered longitudinal study, changes in tractive force during the different lunar phases did not influence the incidence of renal colic admissions in emergency department.

    Acute renal infarction is an uncommon and under-diagnosed disease. Its clinical presentation is nonspecific and often mimics other more common disease entities. The diagnosis is usually missed or delayed, which frequently results in irreversible renal parenchyma damage. High index of suspicion is required for early diagnosis, as timely intervention may prevent loss of kidney function. We report a case of acute renal infarction following coronary angiography in a patient with paroxysmal atrial fibrillation who initially presented with acute abdominal pain mimicking appendicitis.

    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.

    Currently, partial hepatectomy is the treatment of choice for a wide variety of liver and biliary conditions. Among the possible complications of partial hepatectomy, acute kidney injury(AKI) should be considered as an important cause of increased morbidity and postoperative mortality. Difficulties in the data analysis related to postoperative AKI after liver resections are mainly due to the multiplicity of factors to be considered in the surgical patients, moreover, there is no consensus of the exact definition of AKI after liver resection in the literature, which hampers comparison and analysis of the scarce data published on the subject. Despite this multiplicity of risk factors for postoperative AKI after partial hepatectomy, there are main factors that clearly contribute to its occurrence. First factor relates to large blood losses with renal hypoperfusion during the operation, second factor relates to the occurrence of post-hepatectomy liver failure with consequent distributive circulatory changes and hepatorenal syndrome. Eventually, patients can have more than one factor contributing to post-operative AKI, and frequently these combinations of acute insults can be aggravated by sepsis or exposure to nephrotoxic drugs.

    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

    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.

    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.

    The clinical manifestations of drug-induced renal disease may include all the manifestations attributed to natural or spontaneous renal diseases such as acute renal failure, chronic renal failure, acute nephritic syndrome, renal colic, haematuria, selective tubular defects, obstructive nephropathy, etc. It is therefore vital in any patient with renal disease whatever the clinical manifestations might be, to obtain a meticulous drug and toxin inventory. Withdrawal of the offending drug may result in amelioration or cure of the renal disorder although in the case of severe renal failure it may be necessary to utilise haemodialysis or peritoneal dialysis to tide the patient over the period of acute renal failure. Analgesic nephropathy is an important cause of terminal chronic renal failure and it is therefore vital to make the diagnosis as early as possible. The pathogenesis of some drug-induced renal disorders appears to be immunologically mediated. There are many other pathogenetic mechanisms involved in drug-induced renal disorders and some drugs may under appropriate circumstances be responsible for a variety of different nephrotoxic effects. For example, the sulphonamides have been incriminated in examples of crystalluria, acute interstitial nephritis, acute tubular necrosis, generalised hypersensitivity reactions, polyarteritis nodosa and drug-induced lupus erythematosus.

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

    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.

    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.

    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.

    Addison's disease is a rare condition. Its onset of symptoms most often is nonspecific contributing to a diagnostic and therapeutic delay. Acute renal failure can be the first manifestation of this disease. We report the case of a patient with Addison's disease who was initially treated for acute renal failure due to multiple myeloma and whose diagnosis was adjusted thereafter. Patient's condition dramatically improved after treatment with intravenous rehydration; injectable hydrocortisone.

    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.

    Acute renal cortical necrosis in which there is destruction of the renal cortex and sparing of the renal medulla, is a relatively rare cause of acute renal failure. A definitive diagnosis of acute renal cortical necrosis is based on renal biopsy, but on CT(computed tomography) the rather specific contrast-enhanced appearance of acute renal cortical necrosis has been described. As renal biopsy is not available, contrast-enhanced CT is a useful, noninvasive investigate modality for the early diagnosis of acute renal cortical necrosis. We report the characteristic CT findings of acute renal cortical necrosis in a patient with acute renal failure following an operation for abdominal trauma.

    Full Text Available Genes involved in acute rejection (AR after organ transplantation remain to be further elucidated. In a previous work we have demonstrated the under-expression of VE-Cadherin by endothelial cells (EC in AR following murine and human heart transplantation. Serial sections from 15 human kidney Banff-graded transplant biopsies were examined for the presence of VE-Cadherin and CD34 staining by immunohistochemistry (no AR (n=5, AR grade IA (n=5, or AR grade IIA (n=5. Quantification of peritubular EC staining were evaluated and results were expressed by the percentage of stained cells per surface analysed. There was no difference in CD34 staining between the 3 groups. VE-Cadherin expression was significantly reduced in AR Grade IIA when compared to no AR (P=.01 and to AR grade IA (P=.02. This study demonstrates a reduced VE-Cadherin expression by EC in AR after renal transplantation. The down-regulation of VE-Cadherin may strongly participate in human AR.

    Full Text Available Acute kidney injury (AKI independently increases morbidity and mortality in children admitted to the hospital. Renal replacement therapy (RRT is an essential therapy in the setting of AKI and fluid overload. The decision to initiate RRT is complex and often complicated by concerns related to patient hemodynamic and thermodynamic instability. The choice of which RRT modality to use depends on numerous criteria that are both patient and treatment center specific. Surprisingly, despite decades of use, no randomized, controlled trial study involving RRT in pediatrics has been performed. Because of these factors, clear-cut consensus is lacking regarding key questions surrounding RRT delivery. In this paper, we will summarize existing data concerning RRT use in children. We discuss the major modalities and the data-driven specifics of each, followed by controversies in RRT. As no standard of care is in widespread use for RRT in AKI or in multiorgan disease, we conclude in this paper that prospective studies of RRT are needed to identify best practice guidelines.

    Acute kidney injury (AKI) is a common problem in hospitalized patients and is associated with significant morbidity and mortality. Two large trials showed no benefit from increased doses of renal replacement therapy (RRT) despite previous clinical data suggesting that increased clearance from RRT has beneficial effects. Since infection is the leading cause of death in AKI, my group and others hypothesized that increased RRT antibiotic clearance might create a competing morbidity. The data from my group, as well as those of other groups, show that many patients are underdosed when routine "1 size fits all" antibiotic dosing is used in patients with AKI receiving continuous RRT (CRRT). Here, concepts of drug distribution and clearance in AKI are briefly discussed and then 1 antibiotic (piperacillin) is discussed in depth to illustrate the challenges in applying the medical literature to clinical practice. The fact that published data on drug dosing in AKI and dialysis reflect the evolution of practice patterns and often do not apply to present prescribing habits is also discussed. A more general approach to drug dosing facilitates situation-specific prescribing by the nephrologist and critical care specialist. Copyright © 2013 National Kidney Foundation, Inc.

Methods:160 renal colic patients were randomly divided into 2 groups with 80 patients in each group:the patients in diclofenac group were treated with diclofenac intramuscular injection and phloroglucinol intravenous drip;while patients in tramadol group were treated with tramadol intramuscular injection and phloroglucinol intravenous drip. The therapeutic effects, pain began to relieve time and complete response time, as well as adverse reactions of patients in 2 groups were observed. Results:The effective rate of diclofenac group was 92.5%(58/80), which was obviously higher than tramadol group (P<0.05). The pain began to relieve time and complete response time of diclofenac group were all signiifcantly shorter than tramadol group (P<0.05). The adverse reaction rate of diclofenac group was obviously lower than tramadol group (P<0.05). Conclusions:Treating renal colic with diclofenac combined phloroglucinol can get deifnite therapeutic effects, so it is worthy of spreading in clinic.

    A nephritic colic is one of the most common pictures of urologic conditions, a primary causes being the occurrence of lithiasis concretions along the urinary tract. A series of 140 cases of nephritic colic diagnosed in the emergency ward and later referred to our office for follow-up are presented here. The relevance of the physical examination is emphasized, pointing out that with practice the simple performance of abdominal X-ray, ultrasound and urinary sediments is usually enough to reach a certainty diagnosis. There is, however, near 10% cases where it is necessary to carry out contrast studies or endoscopic manoeuvres to be able to differentiate a nephritic colic from other conditions. The primary aim of treatment is to overcome pain, facilitate the advance of the lithiasis obstacle and to preserve the renal function. A description is made of the various drugs used, while endoscopic manoeuvres are reserved for the more selected cases of compromised kidney or when the patient's general condition so requires.

    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.

    Full Text Available Acute lymphoblastic leukemia (ALL is the most common malignancy in the pediatric patient population. However, renal involvement as the primary manifestation of ALL is rare. We report a case of a 4-year-old boy with bilateral renal lesions resembling nephroblastic rests as the first finding of early stage ALL preceding hematological changes and subsequent classic clinical findings by two weeks. These renal hypodensities completely resolved after one week of induction chemotherapy. This case demonstrates that renal involvement can be the only initial presenting finding of leukemia. Children with lesions resembling nephroblastic rests need appropriate surveillance due to the risk of malignant disease.

    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.

    The clinical manifestation of renal vein thrombosis varies with the speed and degree of venous occlusion. Such patients may be asymptomatic, have minor nonspecific symptoms such as nausea or weakness, or have more specific symptoms such as upper abdominal pain, flank pain, or hematuria. Acute scrotal pain is a very uncommon clinical expression of renal vein thrombosis. Here, we report a case of membranous glomerulonephritis-induced renal vein thrombosis presented with the symptom of acute scrotal pain caused by thrombosis-induced varicocele. This case report suggests that renal vein thrombosis should be considered in the diagnosis of acute scrotal pain; it also emphasizes that an investigation of retroperitoneum should be performed for adult patients with the sudden onset of varicocele.

    2017-04-01

    Question Acute pyelonephritis in children is of great concern and I usually refer these patients to a pediatrician or send them to the emergency department owing to the risk of renal scarring. Are steroids an acceptable treatment to reduce risk of scarring? Answer Several agents have been studied in an effort to prevent renal scar formation following acute pyelonephritis in children. Use of corticosteroids, in conjunction with standard therapy for acute pyelonephritis, shows promising findings. However, evidence is very limited and steroids should not be offered on a regular basis as part of treatment. Copyright© the College of Family Physicians of Canada.

    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 kidney injury (AKI is a recognised complication of intravenous pentamidine therapy. A direct nephrotoxic effect leading to acute tubular necrosis has been postulated. We report a case of severe renal allograft dysfunction due to nebulised pentamidine. The patient presented with repeated episodes of AKI without obvious cause and acute tubular necrosis only on renal histology. Nebulised pentamidine was used monthly as prophylaxis for Pneumocystis jirovecii pneumonia, and administration preceded the creatinine rise on each occasion. Graft function stabilised following discontinuation of the drug. This is the first report of nebulized pentamidine-induced reversible nephrotoxicity in a kidney allograft. This diagnosis should be considered in a case of unexplained acute renal allograft dysfunction.

    Colic in infants causes one in six families (17%) with children to consult a health professional. One systematic review of 15 community-based studies found a wide variation in prevalence, which depended on study design and method of recording. We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for colic in infants? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 27 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: advice to increase carrying, advice to reduce stimulation, casein hydrolysate milk, cranial osteopathy, crib vibrator device, focused counselling, gripe water, infant massage, low-lactose milk, simethicone, soya-based infant feeds, spinal manipulation, and whey hydrolysate milk.

    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.

    The purpose of this study was to assess the incidence of spontaneous renal artery dissection (SRAD) as a cause of acute renal infarction, and to evaluate the clinical and multidetector computed tomography (MDCT) findings of SRAD. From November 2011 to January 2014, 35 patients who were diagnosed with acute renal infarction by MDCT were included. We analyzed the 35 MDCT data sets and medical records retrospectively, and compared clinical and imaging features of SRAD with an embolism, using Fisher's exact test and the Mann-Whitney test. The most common cause of acute renal infarction was an embolism, and SRAD was the second most common cause. SRAD patients had new-onset hypertension more frequently than embolic patients. Embolic patients were found to have increased C-reactive protein (CRP) more often than SRAD patients. Laboratory results, including tests for lactate dehydrogenase (LDH) and blood urea nitrogen (BUN), and the BUN/creatinine ratio (BCR) were significantly higher in embolic patients than SRAD patients. Bilateral renal involvement was detected in embolic patients more often than in SRAD patients. MDCT images of SRAD patients showed the stenosis of the true lumen, due to compression by a thrombosed false lumen. None of SRAD patients progressed to an estimated glomerular filtration rate renal disease during the follow-up period. SRAD is not a rare cause of acute renal infarction, and it has a benign clinical course. It should be considered in a differential diagnosis of acute renal infarction, particularly in patients with new-onset hypertension, unilateral renal involvement, and normal ranges of CRP, LDH, BUN, and BCR.

  11. Renal functional reserve and renal recovery after acute kidney injury.

    Renal functional reserve (RFR) represents the capacity of the kidney to increase glomerular filtration rate (GFR) in response to certain physiological or pathological stimuli or conditions. Once baseline GFR is determined, RFR can be assessed clinically after an oral protein load or intravenous amino acid infusion. In clinical practice, baseline GFR displays variable levels due to diet or other factors. RFR is the difference between peak 'stress' GFR induced by the test (p.o. or i.v.) and the baseline GFR. In clinical scenarios where hyperfiltration is present (high baseline GFR due to pregnancy, hypertension or diabetic nephropathy, in solitary kidney or kidney donors), RFR may be fully or partially used to achieve normal or supranormal renal function. Since commonly used renal function markers, such as GFR, may remain within normal ranges until 50% of nephrons are lost or in patients with a single remnant kidney, the RFR test may represent a sensitive and early way to assess the functional decline in the kidney. RFR assessment may become an important tool to evaluate the ability of the kidney to recover completely or partially after a kidney attack. In case of healing with a defect and progressive fibrosis, recovery may appear complete clinically, but a reduced RFR may be a sign of a maladaptive repair or subclinical loss of renal mass. Thus, a reduction in RFR may represent the equivalent of renal frailty or susceptibility to insults. The main aim of this article is to review the concept of RFR, its utility in different clinical scenarios, and future perspective for its use.

    Objective:To evaluate the therapeutic safety and efficacy of double-J stent in renal colic combined with pregnancy. Methods: Clinical data of 22 patients of renal colic during pregnancy who were treated with double-J stent in Shengjing hospital from June 2000 to November 2010 were collected and retrospectively analyzed. Results:All the patients received the double-J stent insertion and the subsequent anti-infection treatment. After 1 ~5 days of all the treatment, the symptoms of pain, fever, nausea and vomiting in all patients were obviously relieved. Three days after the treatment, the percentage of microscopic hematuria, pyu-ria, elevated white blood cell, elevated serum creatinine and urinary nitrogen was decreased, compared to the preoperative level. One month after the treatment, the hydronephrosis of 16 patients were vanished and the hydronephrosis in another 6 patients were alleviated. All patients had no pregnancy complications, while only one patient had symptoms of renal colic and fever near three months after the treatment of double-J stent. The retention time of double-J stent in all patients varied from 1 to 7 months, the average retention time was 3.4 months. Among the 22 patients,21 patients successfuly delivery, only one patient took induced a-bortion as the left tuberculous exative pleurisy. Conclusions: For pregnant women with renal colic, if conservative management fails, the double-J stent treatment is a less invasive and efficient method to relieve the pain and control the hydronephrosis.%目的:探讨留置双J管治疗妊娠期肾绞痛的有效性及安全性.方法:回顾性分析2000年6月至2010年11月因肾绞痛就诊于盛京医院泌尿外科及产科并留置双J管治疗的22例妊娠期患者的临床资料.分析其临床特征,并观察留置双J管治疗的疗效.结果:所有患者在留置双J管和辅助抗感染治疗后,肾绞痛、发热及恶心、呕吐等症状均于治疗后1~5天明显缓解;术后3

    The usefulness of the renal scan in diagnosing technical complications in the transplant patient is well established. However, the ability of the renal scan to differentiate between acute rejection and acute tubular necrosis has remained uncertain. We have evaluated the effectiveness of the /sup 99m/Tc DTPA computer-derived time-activity curve of renal cortical perfusion, as well as data obtained from scintillation camera images, in making such diagnoses. Fifteen patients with a clinical diagnosis of either acute rejection or acute tubular necrosis, or both, were studied retrospectively. Technetium scan diagnoses did not agree with the clinical assessment in nine of the patients. Thus selection of a course of treatment should not be based on data obtained from the scan alone.

    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.

    This paper reports on the association between renal sinus hyperechogenicity and acute pyelonephritis. The medical records and imaging studies of 18 children displaying this pattern were retrospectively studied. Thickening of the renal pelvis and renal enlargement were the most frequent associated sonographic abnormalities. Further subtle findings can be found on sonography and colour/power Doppler. Their identification can help in the diagnostic approach to acute pyelonephritis and may obviate the need for other imaging modalities such as enhanced CT or {sup 99} {sup m}Tc-DMSA scintigraphy. Renal sinus hyperechogenicity was also identified in a parallel study performed in female rabbits with experimental pyelonephritis and was shown, histologically, to be related to exudates of fibrin and polymorphonuclear leukocytes, interstitial oedema and micro-abscesses.

    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 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.

    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.

    Full Text Available A 14-year-old boy presented with asymptomatic right hydronephrosis detected on routine yearly ultrasound examination. Previously, he had at least two normal renal ultrasonograms, 4 years after remission of acute myeloblastic leukemia, treated by AML-BFM-93 protocol. A function of the right kidney and no damage on the left was confirmed by a DMSA scan. Right retroperitoneoscopic nephrectomy revealed 3 renal arteries with the lower pole artery lying on the pelviureteric junction. Histologically chronic tubulointerstitial nephritis was detected. In the pathogenesis of this severe unilateral renal damage, we suspect the exacerbation of deleterious effects of cytostatic therapy on kidneys with intermittent hydronephrosis.

    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.

    `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.

    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.

    Full Text Available At present, the diagnosis of renal allograft rejection requires a renal biopsy. Clinical management of renal transplant patients would be improved if rapid, noninvasive and reliable biomarkers of rejection were available. This study is designed to determine whether such protein biomarkers can be found in renal-graft tissue proteomic approach. Orthotopic kidney transplantations were performed using Fisher (F344 or Lewis rats as donors and Lewis rats as recipients. Hence, there were two groups of renal transplant models: one is allograft (from F344 to Lewis rats; another is syngrafts (from Lewis to Lewis rats serving as control. Renal tissues were collected 3, 7 and 14 days after transplantation. As many as 18 samples were analyzed by 2-D Electrophoresis and mass spectrometry (MALDI-TOF-TOF-MS. Eleven differentially expressed proteins were identified between groups. In conclusion, proteomic technology can detect renal tissue proteins associated with acute renal allograft rejection. Identification of these proteins as diagnostic markers for rejection in patients′ urine or sera may be useful and non-invasive, and these proteins might serve as novel therapeutic targets that also help to improve the understanding of mechanism of renal rejection.

    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

Baseline regimen of mycophenolate mofetil (MMF), cyclosporin (CsA), methylprednisolone (MPD) and prednisone (Pred) were administered to all patients. The treatment of Daclizumab was based on baseline regimen. The Daclizumab group received Daclizumab twice before and after renal transplant. The occurrence of post-transplantation acute rejection, renal function and T lymphocyte subtypes were sequentially monitored; meanwhile adverse events, infection episode, and patient and graft survival were observed.All of patients received a follow-up of 12 months at least. Results :The occurrence of acute rejection in Daclizumab group in 1,3, 6 and 12 months after renal transplantation was 7.7%, 19.2%, 23.1% and 30.8%, respectively,while it was 15.6% ,28.9%,35.6% and 46.7% in the control group. There was significant difference between the two group(P < 0.05). There was no difference in infection episodes and adverse events between the Daclizumab group and control group. One year patient survival was 92.3% in Daclizumab group, 91.1% in control group (P > 0.05), compared with graft survival of 96.2 % and 93.3 % for Daclizumab and control group, respectively (P > 0. 05). The renal function in Daclizumab group in 1, 6 and 12 months after renal transplantation was better than that in control group (P < 0.05). The CD3+ and CD4+ subtypes decreased in both two groups after operation but no significant difference (P > 0.05). Conclusion:Daclizumab combined with MMF, CsA, MPD and Pred therapeutic regimen was effective to reduce the occurrence of acute rejection in renal transplant recipients and have no influence on T lymphocyte subtypes.

    Full Text Available Infantile colic is a distressing condition in infants, pathogenesis of which is still not clear. Several treatment strategies have been attempted before, but only some of them proven successful. The aim of this paper is to review studies on treatment options for infantile colic. For this, a systematic literature review was done on studies regarding pathophysiology, medical and conventional interventions for infantile colic from 1954 to March 2011. Forty nine articles included in Cochrane database were reviewed. Fourteen studies on pathophysiology and risk factors, 7 studies on effect of infantlie colic on parents and family,19 studies on management, 5 studies on other related factors and 4 literature reviews were included for review. Pathophysiology has been described in various ways in different studies and yet not conclusive. Regarding studies on management, simethicone could not significantly control colic, dicyclomine hydrochloride had serious side effects and cimetropium bromide results were favourable, but milder side effects were noted. Some nutritional studies reported low-allergen maternal diets in breastfed infants but suitability of these methods are questionable in Bangladesh. Behavioural studies on the use of decreased stimulation and contingent music were favourable in some studies. Mixed herbal tea and probiotic like Lactobacillus reuteri studies showed encouraging results. There are some scientific evidences to support a low-allergen maternal diet in breastfed infants with infantile colic. Some encouraging results exist for mixed herbal tea, cimetropium bromide and probiotics.

    Acute renal infarction (ARI) is a rare disease. ARI causes decline in renal function in both the acute and chronic phases. However, the correlation between the volume of the infarction and degree of renal function decline has not been fully investigated. Therefore, we aimed to examine the relationship between the volume of the infarction and degree of renal function decline. We performed a single-center, retrospective, observational study investigating clinical parameters and the volume of the infarction. The volume of the infarction was measured using reconstructed computed tomography data. A total of 39 patients (mean age, 72.6 ± 13.2 years; men, 59%) were enrolled. The median infarction volume was 45 mL (interquartile range, 14-91 mL). The volume of the infarction was significantly associated with the peak lactate dehydrogenase (LDH) level (median, 728 IU/L; interquartile range, 491-1227 U/L) (r = 0.58, p function decline in both acute and chronic phases (r = -0.44, -0.38, respectively, p LDH level was significantly correlated with the degree of renal function decline in the acute phase but not in the chronic phase (r = -0.35, -0.21; p function decline in ARI. Therefore, assessment of infarct volume in ARI is important.

  12. Preventing acute renal failure is crucial during acute tumor lysis syndrome

    Full Text Available Tumour Lysis syndrome (TLS is characterized by the massive destruction of tumoral cells and the release in the extracellular space of their content. While TLS may occur spontaneously before treatment, it usually develops shortly after the initiation of cytotoxic chemotherapy. These metabolites can overwhelm the homeostatic mechanisms and cause hyperuricemia, hyperkalemia, hyperphosphatemia and hypocalcemia. Moreover, TLS may lead to an acute renal failure (ARF. In addition to the hospital mortality induced by the acute renal failure itself, development of an ARF may preclude optimal cancer treatment. Therefore, prevention of the acute renal failure during acute tumor lysis syndrome is mandatory. The objective of this review is to describe pathophysiological mechanisms leading to acute tumor lysis syndrome, clinical and biological consequences of this syndrome and to provide up-to-date guidelines to ensure prevention and prompt management of this syndrome.

  13. Renal parenchymal oxygenation and hypoxia adaptation in acute kidney injury.

    Rosenberger, Christian; Rosen, Seymour; Heyman, Samuel N

    2006-10-01

    The pathogenesis of acute kidney injury (AKI), formally termed acute tubular necrosis, is complex and, phenotypically, may range from functional dysregulation without overt morphological features to literal tubular destruction. Hypoxia results from imbalanced oxygen supply and consumption. Increasing evidence supports the view that regional renal hypoxia occurs in AKI irrespective of the underlying condition, even under circumstances basically believed to reflect 'direct' tubulotoxicity. However, at present, it is remains unclear whether hypoxia per se or, rather, re-oxygenation (possibly through reactive oxygen species) causes AKI. Data regarding renal hypoxia in the clinical situation of AKI are lacking and our current concepts regarding renal oxygenation during acute renal failure are presumptive and largely derived from experimental studies. There is robust experimental evidence that AKI is often associated with altered intrarenal microcirculation and oxygenation. Furthermore, renal parenchymal oxygen deprivation seems to participate in the pathogenesis of experimental AKI, induced by exogenous nephrotoxins (such as contrast media, non-steroidal anti-inflammatory drugs or amphotericin), sepsis, pigment and obstructive nephropathies. Sub-lethal cellular hypoxia engenders adaptational responses through hypoxia-inducible factors (HIF). Forthcoming technologies to modulate the HIF system form a novel potential therapeutic approach for AKI.

    This study aimed to characterize the influence of acute renal artery stenosis on cyclooxygenase-2 (COX-2) and renin expression in the juxtaglomerular apparatus. For this purpose, male Sprague-Dawley rats received a left renal artery clip, and COX-2 mRNA, COX-2 immunoreactivity, plasma renin...... causal relationship between the changes of COX-2 and of renin expression, clipped rats were treated with the COX-2 blocker celecoxib (40 mg. kg(-1). day(-1)). This treatment, however, did not change renin mRNA either in the clipped or in the contralateral intact kidney. Our findings indicate that renal...... artery stenosis causes ipsilaterally an acute upregulation and contralaterally a downregulation of juxtaglomerular COX-2 expression. The lacking effect of celecoxib on renin gene expression does not support the concept of a direct mediator function of COX-2-derived prostaglandins in the control of renin...

  15. 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 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.

    Acute renal injury caused by acute necrotizing pancreatitis (ANP) is a common complication that is associated with a high rate of mortality. Paeoniflorin is the active ingredient of paeonia radix and exhibits a number of pharmacological effects, such as anti‑inflammatory, anticancer, analgesic and immunomodulatory effects. The present study detected the potential treatment effects of paeoniflorin on acute renal injury induced by ANP in a rat model. The optimal dose of paeoniflorin for preventing acute renal injury induced by ANP was determined. Then, the possible protective mechanism of paeoniflorin was investigated. The serum levels of tumor necrosis factor (TNF)‑α, interleukin (IL)‑1β and IL‑6 were measured with enzyme‑linked immunosorbent assay kits. Renal inflammation and apoptosis were measured by immunohistochemistry and terminal deoxynucleotidyl transferase‑mediated dUTP nick end labeling assay. The expression of nitric oxide in kidney tissues was also evaluated. The p38 mitogen‑activated protein kinases (MAPKs) were measured by western blotting. The results shown that paeoniflorin may ameliorate acute renal injury following ANP in rats by inhibiting inflammatory responses and renal cell apoptosis. These effects may be associated with the p38MAPK and nuclear factor‑κB signal pathway.

    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.

    Full Text Available Nephrolithiasis are multi-factorial diseases that result from the combined influence of epidemiological, biochemical and genetically risk factors. Defective drainage due to urinary tract obstruction at the narrowest part (ureterovesical junction, ureteropelvic junction, and near the pelvic brim via stones will eventually cause the agonizing renal colic pain. Therapeutic managements of nephrolithiasis to relief acute colic pain are the primary objective. Non-steroidal anti-inflammatory drugs are the most commonly used drugs as suggested by many studies. It is very important to consider side effects of the drugs used in the treatment of colic pain. In order to preserve renal function and to relief obstruction, medical expulsion therapy are used for urethral calculi as a conservative management. These medications will aid the passage urethral calculi, an area that currently seems to be a field for continuous investigation.

    Rapid and reliable biomarkers of renal allograft rejection have not been available. This study aimed to investigate biomarkers in renal allograft tissue using proteomic analysis. Orthotopic kidney transplantations were performed using Fisher (F344) or Lewis rats as donors and Lewis rats as recipients. Syngenic control group (Group I) constituted F344-to-F344 orthotopic kidney allo-transplantations (n = 8); and allogenic group (Group II) consisted of F344-to-Lewis orthotopic kidney allo-transplantations (n = 8). Renal tissues were harvested 7 days after transplantation. Samples were analyzed using 2-D electrophoresis and matrix assisted laser desorption ionization-time of flight mass spectrometry. 6 differentially expressed proteins were identified between allogenic group and syngenic control group. A rat model of acute renal allograft rejection was successfully set up. Differentially expressed proteins in renal allograft tissue of rat were detected using proteomic analysis and might serve as novel diagnostic and therapeutic targets in human. Quantitative proteomics, using MALDL-TOF-MS methodology has the potential to provide a profiling and a deeper understanding of acute renal rejection.

    The objectives of this study were to define the acute and chronic effects of 1-hour unilateral in vivo renal ischemia on renal function and histology in cats. Twenty-one adult purpose-bred research cats were anesthetized, and 1 kidney underwent renal artery and vein occlusion for 1 hour. Serum creatinine and urea concentrations, urine protein:creatinine ratio, urine-specific gravity, glomerular filtration rate, hematocrit, platelet concentration and function, and white blood cell count were measured at baseline and variable time points after ischemia. Renal histopathology was evaluated on days 3, 6, 12, 21, 42, and 70 postischemia; changes in smooth muscle actin and interstitial collagen were examined. Following ischemia, whole animal glomerular filtration rate was significantly reduced (57% of baseline on day 6; P acute epithelial necrosis accompanied by evidence of regeneration of tubules predominantly within the corticomedullary junction. At later periods, postischemic kidneys had evidence of tubular atrophy and interstitial inflammation with significantly more smooth muscle actin and interstitial collagen staining and interstitial fibrosis when compared with the contralateral control kidneys. This study characterizes the course of ischemic acute kidney injury in cats and demonstrates that ischemic acute kidney injury triggers chronic fibrosis, interstitial inflammation, and tubular atrophy in feline kidneys. These late changes are typical of those observed in cats with naturally occurring chronic kidney disease.

    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.

    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.

    2009-10-01

    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.

    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.

    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.

    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.

    The authors report on a rare case of neonatal scrotal oedema occurring concurrently with pain upon palpation of the spermatic cord on the first day of life. An ultrasound examination showed poor perfusion of the left testicle and a thrombosis of the left renal vein; intraoperative exploration indicated necrosis of the left testicle without signs of torsion. Gorged vessels with paravasal bleeding were found in the spermatic cord. The authors hypothesise that necrosis of the testicle may result from haemorrhagic infarction caused by renal venous thrombosis. Acute scrotal discolouration with pain upon palpation in neonates is usually attributed to testicular torsion. The authors report a case where these symptoms had a different cause.

  19. Growth factors and cytokines in acute renal failure.

    The mammalian kidney is susceptible to injury by ischemia/reperfusion and toxins, and regeneration after injury is characterized by hyperplasia and recovery of the damaged epithelial cells that line the tubules. Locally produced growth factors may serve as mediators of nephrogenesis and differentiation during renal development and of renal regeneration after acute injury. In cultured cells, administration of one or a mixture of growth factors to quiescent cells will initiate progression through the cell cycle and cell division. In the adult kidney, cell division normally is very low, but will increase up to 10-fold after acute injury. In addition to proliferation after lethal injury, there also is cellular repair in cells that have undergone sublethal injury. Recent studies indicate that growth factors inhibit programmed cell death in response to acute injury. Growth factors also may initiate or promote protein and lipid biosynthesis and provide an intracellular milieu that promotes cellular repair. In addition to cellular repair, growth factors also may be involved in the re-establishment of cell-extracellular matrix and cell-cell integrity. Finally, growth factors may limit injury by decreasing the factors that induce damage. Increased local renal expression of growth factors in response to acute injury include heparin binding epidermal growth factor (HB-EGF), hepatocyte growth factor (HGF), insulin-like growth factor-I (IGF-I), transforming growth factor-beta, parathyroid hormone-related peptide, and acidic fibroblast growth factor. In a number of experimental models of acute renal injury, administration of exogenous growth factors has been shown to accelerate both structural and functional recovery. Specifically, EGF, IGF-1, and HGF all have been shown to be effective in this regard. These studies are reviewed and potential therapeutic uses of growth factors and cytokines will be discussed.

    Full Text Available Acute disseminated encephalomyelitis (ADEM, seen mostly in children, is an acute demyelinating disease, affecting mainly the white matter of brain and spinal cord. We report an unusual case of ADEM in an 11-year old boy with end-stage renal disease, who underwent hemopoietic stem cell transplantation prior to renal transplantation. He needed admission to the intensive care unit and required mechanical ventilation. He responded to intravenous injection of steroids and upon recovery, underwent renal transplantation successfully.

    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.

    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.

    This study aimed to characterize the influence of acute renal artery stenosis on cyclooxygenase-2 (COX-2) and renin expression in the juxtaglomerular apparatus. For this purpose, male Sprague-Dawley rats received a left renal artery clip, and COX-2 mRNA, COX-2 immunoreactivity, plasma renin...... activity, and renin mRNA levels were determined. COX-2 mRNA and COX-2 immunoreactivity in the macula densa region in the clipped kidneys increased as early as 6 h after clipping and reached a maximal expression 1-2 days after clipping. Although values for plasma renin activity were elevated markedly at all...... artery stenosis causes ipsilaterally an acute upregulation and contralaterally a downregulation of juxtaglomerular COX-2 expression. The lacking effect of celecoxib on renin gene expression does not support the concept of a direct mediator function of COX-2-derived prostaglandins in the control of renin...

  8. Role of adenosine in tubuloglomerular feedback and acute renal failure.

    Osswald, H; Vallon, V; Mühlbauer, B

    1996-12-01

    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.

  9. Infantile colic, facts and fiction

    Full Text Available Abstract Infantile colic is one of the major challenges of parenthood. It is one of the common reasons parents seek medical advice during their child’s first 3 months of life. It is defined as paroxysms of crying lasting more than 3 hours a day, occurring more than 3 days in any week for 3 weeks in a healthy baby aged 2 weeks to 4 months. Colic is a poorly understood phenomenon affecting up to 30% of babies, underlying organic causes of excessive crying account for less than 5%. Laboratory tests and radiological examinations are unnecessary if the infant is gaining weight normally and has a normal physical examination. Treatment is limited and drug treatment has no role in management. Probiotics are now emerging as promising agents in the treatment of infantile colic. Alternative medicine (Herbal tea, fennel, glucose and massage therapy have not proved to be consistently helpful and some might even be dangerous. In conclusion infantile colic is a common cause of maternal distress and family disturbance, the cornerstone of management remains reassurance of parents regarding the benign and self-limiting nature of the illness. There is a critical need for more evidence based treatment protocols.

  10. Elimination communication as colic therapy.

    Jordan, Geraldine J

    2014-09-01

    Colic is generally defined as excessive crying in early infancy and can have negative consequences on the infant as well as on the infant's family life. Excessive crying can result in escalating parental stress levels, abusive caregiver response, increased risk of shaken baby syndrome and parental postpartum depression. In addition to excessive crying, symptoms and descriptors of infant colic include inconsolable crying, screaming, legs drawn up against the abdomen, furrowing of eyebrows, distended abdomen, arched back, passing gas, post-feeding crying and difficulty defecating. There are few well-designed, reproducible, randomized, large-scale studies which demonstrate efficacy of any therapeutic method for colic. An unexplored etiology is that colic is functionally related to a decrease in stooling frequency. Gut distention may periodically result in intensifying discomfort for the infant and in concomitant inconsolable crying. Elimination communication (EC; also known as Natural Infant Hygiene and sometimes referred to as infant potty training, baby-led potty training or assisted infant toilet training) involves the use of cues by which the infant signals to the caregiver that the infant needs to micturate or defecate. Such cues can include types of crying, squirming, straining, wriggling, grimacing, fussing, vocalizing, intent look at caregiver, red face, passing gas and grunting, many of which are the same initial symptoms related to the onset of colicky infant states. A caregiver's attentive and nurturant response to an infant's cues involve uncovering the infant's intergluteal cleft and cradling the infant gently and non-coercively in a supported, secure squatting position. This position will increase the infant's anorectal angle thus facilitating complete defecation. It is hypothesized that effective and timely elimination will cause increased physical comfort for the infant; colic symptoms will concomitantly decrease.

    Renal impairment influences the prognosis of patients with cardiovascular disease and increases cardiovascular risk. Renal dysfunction is a marker of lesions in other parts of the vascular tree and detection facilitates early identification of individuals at high risk of cardiovascular events. In patients with cardiovascular disease, renal function is assessed by measuring albuminuria in a spot urine sample and by estimating the glomerular filtration rate using creatinine-derived predictive formulas or equations. We recommend the Chronic Kidney Disease Epidemiology Collaboration or the Modification of Diet in Renal Disease formulas. The Cockcroft-Gault formula is a possible alternative. The administration of drugs that block the angiotensin-renin system can, on occasion, be associated with acute renal dysfunction or hyperkalemia. We need to know when risk of these complications exists so as to provide the best possible treatment: prevention. Given the growing number of diagnostic and therapeutic procedures in the field of cardiology that use intravenous contrast media, contrast-induced nephrotoxicity represents a significant problem. We should identify the risk factors and patients at greatest risk, and prevent it from appearing.

    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.

  15. 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 toxicity is a hallmark of uranium exposure, with uranium accumulating specifically in the S3 segment of the proximal tubules causing tubular damage. As the distribution, concentration and dynamics of accumulated uranium at the cellular level is not well understood, here, we report on high-resolution quantitative in situ measurements by high-energy synchrotron radiation X-ray fluorescence analysis in renal sections from a rat model of uranium-induced acute renal toxicity. One day after subcutaneous administration of uranium acetate to male Wistar rats at a dose of 0.5 mg uranium kg(-1) body weight, uranium concentration in the S3 segment of the proximal tubules was 64.9 ± 18.2 µg g(-1) , sevenfold higher than the mean renal uranium concentration (9.7 ± 2.4 µg g(-1) ). Uranium distributed into the epithelium of the S3 segment of the proximal tubules and highly concentrated uranium (50-fold above mean renal concentration) in micro-regions was found near the nuclei. These uranium levels were maintained up to 8 days post-administration, despite more rapid reductions in mean renal concentration. Two weeks after uranium administration, damaged areas were filled with regenerating tubules and morphological signs of tissue recovery, but areas of high uranium concentration (100-fold above mean renal concentration) were still found in the epithelium of regenerating tubules. These data indicate that site-specific accumulation of uranium in micro-regions of the S3 segment of the proximal tubules and retention of uranium in concentrated areas during recovery are characteristics of uranium behavior in the kidney.

    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.

    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. Serum creatinine values improved after 48 days. At six months following the

    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

    Full Text Available Acute kidney injury (AKI is a common complication in patients with severe burn injury and one of the major causes of death. It has a negative prognostic value and almost always develops in the context of multiple organ dysfunction syndrome (MODS induced by sepsis. Over the last 20 years, according to data avaliable, the mortality rate has been reported to reach about 75%. Several definitions of AKI have been used , but nowadays the RIFLE classification is considered the gold standard, enabling a more objective comparison of populations. There are several ways to treat AKI in burn patients, including peritoneal dialysis (PD, intermittent hemodialysis, and continuous renal replacement therapy (CRRT. CRRT is generally used in patients in whom intermittent hemodialysis has failed to control hypovolemia, as well as in patients who cannot tolerate intermittent hemodialysis. Additionally, PD is not suitable for patients with burns within the abdominal area. For these reasons, most patients with unstable hemodynamic conditions receive CRRT. In burn patients with acute renal failure the dialytic treatment with continuous renal replacement therapies permitted us to achieve a survival and dialytic adequacy; however, mortality rate is high and related to septic shock and MODS. Despite the wide variation of the analysed burn populations and definitions of AKI, this review clearly showed that AKI remains prevalent and is associated with increased mortality in patients with severe burn injury.

    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.

    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.

    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.

    AIM: To evaluate the effect of ligustrazine, a traditional Chinese medicine, on renal injury in a rat model of acute necrotizing pancreatitis (ANP).METHODS: A total of 192 rats were randomly divided into three groups: control (C group), ANP without treatment (P group), and ANP treated with ligustrazine (T group). Each group was further divided into 0.5,2, 6, 12 h subgroups. All rats were anesthetized with an intraperitoneal injection of sodium pentobarbital.Sodium taurocholate was infused through the pancreatic membrane to induce ANP. T group was infused sodium taurocholate as above, and 0.6% ligustrazine was then administered via the femoral vein. Serum urea nitrogen (BUN) and creatinine (Cr) concentrations were measured for the evaluation of renal function. The effects of ligustrazine on the severity of renal injury were assessed by renal function, TXA2/PGI2 and histopathological changes. Renal blood flow was determined by the radioactive microsphere technique (RMT).RESULTS: Compared with control group, the renal blood flow in P group was decreased significantly. Serious renal and pancreatic damages were found in P group, the BUN and Cr levels were elevated significantly, and the ratio of TXA2 to PGI2 was increased at 2, 6 and 12 h. Compared with P group, the blood flow of kidney was elevated significantly at 6 and 12 h after induction of ANP, the renal and pancreatic damages were attenuated, and the BUN and Cr levels were decreased significantly, and the ratio of TXA2 to PGI2 was decreased at 6 and 12 h in T group.CONCLUSION: Microcirculatory disorder (MCD) is an important factor for renal injury in ANP. Ligustrazine can ameliorate the condition of MCD and the damage of pancreas and kidney.

    Diagnosis and management of acute renal allograft dysfunction often pose challenge to nephrologists during practice. Acute rejection is a major cause of acute graft dysfunction but is rare in patients with leucopenia. Acute rejection can have either humoral or cellular components or sometimes mixed components. Mixed acute cellular and humoral rejection often present as steroid resistant rejection. Here we report a patient with live related renal transplant recipient with acute graft dysfunction with leucopenia who was found to have mixed acute cellular and humoral rejection.

    Catabolism is usually enhanced in acute renal failure (ARF). Its magnitude varies from one patient to another and can change significantly in the same patient from day to day, reflecting its clinical course. It depends on the severity of the ARF, the underlying process, the associated co-morbidity, and therapeutic approach. The detection of patients at high risk for malnutrition is extremely important; nutritional markers and indexes of caloric and protein requirements are useful to adapt renal replacement and nutritional support to ARF patients. Various biochemical parameters (namely, serum albumin and prealbumin), anthropometic measures, indirect calorimetry, urea and creatinine kinetics are all useful tools to evaluate metabolic status and requirements nutritional. Commonly, the caloric requirements are nearly 35 kcal/kg/24 h with correction factors applied for certain clinical situations: carbohydrates account for 50 to 60% of those needs whereas lipids account for the rest. The total amount of fluid administered has to be adapted to the possible ultrafiltration achieved by dialysis. Daily dialysis sessions and continuous renal replacement therapy allow larger volumes and thus facilitate nutritional support. Protein needs frequently exceed 1.2 g/kg/24 h to maintain the nitrogen balance, with a calorie to protein ration close to 150 kcal per g of nitrogen. Sufficient amounts of vitamins and oligo-elements are necessary. Stimulating anabolism by exogenous mediators, such as androgenic hormones or growth factors (rh-IGF1, rh-GH) is an avenue that deserves better definition in critically ill ARF patients.

    Acute renal vein thrombosis (RVT) causes rapid deterioration of renal function if it is not treated aggressively. Conventional anticoagulation therapy is the standard mode of treatment; however, the need for rapid and complete resolution has led to the development of newer modes of treatment such as percutaneous catheter-directed techniques. We describe a case of acute RVT with deteriorating renal functions that highlights the rational of percutaneous catheter-directed combined pharmacomechanical thrombolysis-thrombectomy approach to successfully restore the renal vein patency with improvement of the renal function.

    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.

    Full Text Available Urinary tract infections are common in children. The available gold standard method for diagnosis, Tc-99m dimercaptosuccinic acid scan is expensive and exposes patients to considerable amount of radiation. This study was performed to compare and assess the efficacy of Power Doppler Ultrasound versus Tc-99m DMSA scan for diagnosis of acute pyelonephritis. A quasi experimental study was conducted on 34 children with mean age of 2.82.7 years who were hospitalized with their first episode of febrile urinary tract infection. All children were evaluated in the first 3 days of admission by Doppler Ultrasound and Tc-99m DMSA scan. Patients with congenital structural anomalies were excluded. Each kidney was divided into three zones. The comparison between efficacy of Doppler Ultrasound and DMSA scan was carried out based on number of patients and on classified renal units. Based on the number of patients enrolled; the sensitivity, specificity, positive and negative predictive values and accuracy of Doppler Ultrasound were 89%, 53%, 70%, 80% and 74%, respectively but based on the renal units, it was 66%, 81%, 46%, 91% and 79% , respectively. Although Doppler Ultrasound has the potential for identifying acute pyelonephritis in children, but it is still soon to replace DMSA scan.

    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.

    Estimation of renal function and drug renal disposition in acute kidney injury (AKI), is important for appropriate dosing of drugs and adjustment of therapeutic strategies, but is challenging due to fluctuations in kidney function. Multiphoton microscopy has been shown to be a useful tool in studying drug disposition in liver and can reflect dynamic changes of liver function. We extend this imaging technique to investigate glomerular filtration rate (GFR) and tubular transporter functional change in various animal models of AKI, which mimic a broad range of causes of AKI such as hypoxia (renal ischemia- reperfusion), therapeutic drugs (e.g. cisplatin), rhabdomyolysis (e.g. glycerol-induced) and sepsis (e.g. LPSinduced). The MPM images revealed acute injury of tubular cells as indicated by reduced autofluorescence and cellular vacuolation in AKI groups compared to control group. In control animal, systemically injected FITC-labelled inulin was rapidly cleared from glomerulus, while the clearance of FITC-inulin was significantly delayed in most of animals in AKI group, which may reflect the reduced GFR in AKI. Following intravenous injection, rhodamine 123, a fluorescent substrate of p-glycoprotein (one of tubular transporter), was excreted into urine in proximal tubule via p-glycoprotein; in response to AKI, rhodamine 123 was retained in tubular cells as revealed by slower decay of fluorescence intensity, indicating P-gp transporter dysfunction in AKI. Thus, real-time changes in GFR and transporter function can be imaged in rodent kidney with AKI using multiphoton excitation of exogenously injected fluorescent markers.

    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.

    Acute renal infarction (ARI) is an uncommon disease, whose real incidence is probably higher than expected. It is associated with poor prognosis in a high percentage of cases. To describe the main clinical, biochemical and radiologic features and to determine which factors are associated with poor prognosis (death or permanent renal injury). The following is a retrospective, observational, single-hospital-based study. All patients diagnosed with ARI by contrast-enhanced computed tomography (CT) over an 18-year period were included. Patients were classified according to the cardiac or non-cardiac origin of their disease. Clinical, biochemical and radiologic features were analysed, and multiple logistic regression model was used to determine factors associated with poor prognosis. A total of 62 patients were included, 30 of which had a cardiac origin. Other 32 patients with non-cardiac ARI were younger, had less comorbidity, and were less frequently treated with oral anticoagulants. CT scans estimated mean injury extension at 35%, with no differences observed between groups. A total of 38% of patients had an unfavourable outcome, and the main determinants were: Initial renal function (OR=0.949; IC 95% 0.918-0.980; p=0.002), and previous treatment with oral anticoagulants (OR=0.135; IC 95% 0.032-0.565; p=0.006). ARI is a rare pathology with non-specific symptoms, and it is not associated with cardiological disease or arrhythmias in more than half of cases. A substantial proportion of patients have unfavourable outcomes, and the initial renal function is one of the main prognostic factors. Copyright © 2015 Sociedad Española de Nefrología.

    Federico M. Sarmiento

    2006-01-01

    Full Text Available Acute ureteral obstruction produces renal damage and complications that are proportional to the severity and length of the obstruction. Anatomic diagnosis of the obstruction may be insufficient to manage the patient. Intravenous urogram (IVU is the method usually advised by radiologists to obtain functional information, but requires iodinated contrast agents. IVU anatomic information is superior to anatomic information obtained with renal scintigraphy, but normally the physician already has the anatomic information (unenhanced CT or ultrasound. A renal scan offers better physiologic information than the IVU, has neither adverse effects nor complications, is accurate to confirm or discard significant ureteral obstruction, and depicts obstruction complications. This paper presents a patient with spontaneous urine extravasation secondary to acute renal obstruction who is diagnosed with renal scintigraphy. The authors describe the scintigraphic signs of extraperitoneal, diffuse perinephric, urine extravasation and emphasize the role of renal scintigraphy in diagnosis and follow-up of renal colic.

  20. Renal Cortical Lactate Dehydrogenase: A Useful, Accurate, Quantitative Marker of In Vivo Tubular Injury and Acute Renal Failure.

    Directory of Open Access Journals (Sweden)

    Richard A Zager

    Full Text Available Studies of experimental acute kidney injury (AKI are critically dependent on having precise methods for assessing the extent of tubular cell death. However, the most widely used techniques either provide indirect assessments (e.g., BUN, creatinine, suffer from the need for semi-quantitative grading (renal histology, or reflect the status of residual viable, not the number of lost, renal tubular cells (e.g., NGAL content. Lactate dehydrogenase (LDH release is a highly reliable test for assessing degrees of in vitro cell death. However, its utility as an in vivo AKI marker has not been defined. Towards this end, CD-1 mice were subjected to graded renal ischemia (0, 15, 22, 30, 40, or 60 min or to nephrotoxic (glycerol; maleate AKI. Sham operated mice, or mice with AKI in the absence of acute tubular necrosis (ureteral obstruction; endotoxemia, served as negative controls. Renal cortical LDH or NGAL levels were assayed 2 or 24 hrs later. Ischemic, glycerol, and maleate-induced AKI were each associated with striking, steep, inverse correlations (r, -0.89 between renal injury severity and renal LDH content. With severe AKI, >65% LDH declines were observed. Corresponding prompt plasma and urinary LDH increases were observed. These observations, coupled with the maintenance of normal cortical LDH mRNA levels, indicated the renal LDH efflux, not decreased LDH synthesis, caused the falling cortical LDH levels. Renal LDH content was well maintained with sham surgery, ureteral obstruction or endotoxemic AKI. In contrast to LDH, renal cortical NGAL levels did not correlate with AKI severity. In sum, the above results indicate that renal cortical LDH assay is a highly accurate quantitative technique for gauging the extent of experimental acute ischemic and toxic renal injury. That it avoids the limitations of more traditional AKI markers implies great potential utility in experimental studies that require precise quantitation of tubule cell death.

    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

    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.

Early diagnosis using scintigraphy with technetium-99m-labeled dimercaptosuccinic acid (DMSA scan and early treatment may decrease or prevent development of renal parenchymal lesions. The aim of this study was to assess the occurrence of renal parenchymal lesion in children admitted with a first-time symptomatic UTI and to evaluate the relation between renal parenchymal damage and severity of vesicoureteral reflux (VUR. A total of 102 children with first time acute pyelonephritis (APN were enrolled in the study. All children studied with DMSA scan and ultrasonography (US. Voiding cystourethrography (VCUG was performed in 98 children when urine culture became negative. Changes on the DMSA scan and US were found in 178 (88% and 5 (2.4% out of 203 renal units during the acute phase, respectively. All abnormal renal units on US showed severe parenchymal involvement on DMSA. We also found significant correlation between severity of VUR and abnormal US results on kidneys. Of 40 kidneys with reflux, 38 (95% were found to have abnormal renal scan. Among 155 kidneys with non-refluxing ureters 132 (85.2% revealed parenchymal changes on renal cortical scintigraphy. Kidneys with moderate to severe reflux were more likely to have severe renal involvement. We found a high incidence of renal parenchymal changes in children with APN. Additionally, renal involvement was significantly higher in children with moderate to severe reflux. When there are high-grade VUR and female gender, the risk of renal parenchymal involvement is higher.

    Full Text Available Background Infantile colic is a painful phase in the first months of infancy but no safe and effective conventional treatment exists. Massage is used in traditional medicine as a control and treatment method for infantile colic. The aim of this study is to evaluate the efficacy and safety of massage in the control and treatment of infantile colic. Materials and Methods We searched international database such as PubMed, EMBASE, Cochrane library, and Iranian databases such as SID, Magiran, Iranmedex using a searching strategy with key words "Infantile colic", "Massage", "Complementary of Alternative Medicine" during 2000 to 2015. Analysis of data extraction and quality evaluation of the literature were performed independently by two investigators. Results Most articles provides the strongest evidence for benefits of massage in stress, anxiety reduction, pain control, cancer, skin disease, weight gain, sleep, promote growth, development in premature infants, neuromuscular and gastrointestinal disease such as infantile colic. The infantile colic massage helps relax the gastrointestinal tract and good digestion.   Conclusion Our findings demonstrated that pediatric massage therapy is effective in the treatment of infantile colic.  Compared to other possible treatments for colic, massage is a safe and enjoyable procedure; the risk of serious adverse effects is low. The pediatrician should feel comfortable discussing massage therapy with patients and be able to refer patients to a qualified massage therapist as appropriate.

    Full Text Available The aim of this study was to estimate the diagnostic value of renal cortex copper (Cu concentration in clinical cases of acute copper poisoning (ACP. A total of 97 calves that died due to subcutaneous copper administration were compiled in eleven farms. At least, one necropsy was conducted on each farm and samples for complementary analysis were taken. The degree of autolysis in each necropsy was evaluated. The cases appeared on extensive grazing calf breeding and intensive feedlot farms, in calves of 60 to 200 kg body weight. Mortality varied from 0.86 to 6.96 %, on the farms studied. The first succumbed calf was found on the farms between 6 and 72 hours after the susbcutaneous Cu administration. As discrepancies regarding the reference value arose, the local value (19.9 parts per million was used, confirming the diagnosis of acute copper poisoning in 93% of the analyzed kidney samples. These results confirm the value of analysis of the cortical kidney Cu concentration for the diagnosis of acute copper poisoning.

  6. Renal and urinary levels of endothelial protein C receptor correlate with acute renal allograft rejection.

    Lionel Lattenist

    Full Text Available The Endothelial Protein C Receptor (EPCR is expressed on leukocytes, on endothelium of large blood vessels and to a lesser extent on capillaries. Membrane bound EPCR plays an important role in the activation of protein C which has anticoagulant, anti-inflammatory and cytoprotective effects. After cleavage by a protease EPCR is also found as a soluble protein. Acute rejection of kidney allografts can be divided in T-cell-mediated rejection (TCMR and antibody-mediated (ABMR rejection. The latter is characterized by strong activation of coagulation. Currently no reliable non-invasive biomarkers are available to monitor rejection. Renal biopsies were available from 81 renal transplant patients (33 without rejection, 26 TCMR and 22 ABMR, we had access to mRNA material, matched plasma and urine samples for a portion of this cohort. Renal EPCR expression was assessed by RT-PCR and immunostaining. Plasma and urine sEPCR levels were measured by ELISA. ABMR patients showed higher levels of EPCR mRNA than TCMR patients. EPCR expression on glomeruli was significantly elevated in ABMR patients than in TCMR or control patients. In the peritubular capillaries EPCR expression was higher in ABMR patients than in control patients. EPCR expression was higher in tubules and arteries of rejection patients than in control patients. Plasma sEPCR levels did not differ. Urine sEPCR levels were more elevated in the ABMR group than in patients with TCMR or without rejection. ROC analysis demonstrated that urinary sEPCR is appropriate to discriminate between ABMR patients and TCMR or control patients. We conclude that urinary sEPCR could be a novel non-invasive biomarker of antibody mediated rejection in renal transplantation.

    Background Infantile colic is a condition of unknown origin characterized by paroxysms of crying during the first months of life. A few studies have identified low birth weight (BW) as a risk factor among infants born at term, while the association between gestational age (GA) and infantile colic......, low BW was associated with infantile colic only in infants born at term (gestational weeks 37-41), but not in pre- or post-term infants. Conclusion The results indicate that low birth weight and preterm birth are independently associated with infantile colic. After adjusting for gestational age, low...... birth weight increased the risk of infantile colic in children born at term (gestational weeks 37-41)....

    2012-10-01

    The incidence of acute abdominal pain ranges between 5-10% of all visits at emergency department. Abdominal emergencies of hospital visits may include surgical and non-surgical emergencies. The most common causes of acute abdomen are appendicitis, biliary colic, cholecystitis, diverticulitis, bowel obstruction, visceral perforation, pancreatitis, peritonitis, salpingitis, mesenteric adenitis and renal colic. Good skills in early diagnosis require a sound knowledge of basic anatomy and physiology of gastrointestinal tract, which are reflected during history taking and particularly, physical examination of the abdomen. Advanced diagnostic approaches such as radiography and endoscopy enhance the treatment for acute abdomen including pharmacological and surgical treatment. Therapeutic endoscopy, interventional radiology treatment and therapy using adult laparoscopy are the common modalities for treating patients with acute abdomen.

    BACKGROUND: Renal dysfunction in patients with acute myocardial infarction (MI) is an important predictor of short- and long-term outcome. Cardiac abnormalities dominated by left ventricular (LV) hypertrophy are common in patients with chronic renal dysfunction. However, limited data exists...... on the association between LV systolic- and diastolic function assessed by comprehensive echocardiography and renal dysfunction in contemporary unselected patients with acute MI. METHODS: We prospectively included 1054 patients with acute MI (mean age 63 years, 73% male) and performed echocardiographic assessment...... fraction or GLS attenuated its importance considerably. CONCLUSION: Renal dysfunction in patients with acute MI is independently associated with echocardiographic evidence of increased LV filling pressure. However, the prognostic importance of renal dysfunction is attenuated to a greater degree by LV...

    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 Backgrounds: Criteria that may guide early renal replacement therapy (RRT initiation in patients with acute kidney injury (AKI currently do not exist. Methods: In 120 consecutive patients with AKI, clinical and laboratory data were analyzed on admittance. The prognostic power of those parameters which were significantly different between the two groups was analyzed by receiver operator characteristic curves and by leave-1-out cross validation. Results: Six parameters (urine albumin, plasma creatinine, blood urea nitrogen, daily urine output, fluid balance and plasma sodium were combined in a logistic regression model that estimates the probability that a particular patient will need RRT. Additionally, a second model without daily urine output was established. Both models yielded a higher accuracy (89 and 88% correct classification rate, respectively than the best single parameter, cystatin C (correct classification rate 74%. Conclusions: The combined models may help to better predict the necessity of RRT using clinical and routine laboratory data in patients with AKI.

    Today, infection remains the most common disease of the urinary tract and constitutes almost 75% of patient problems requiring urologic evaluation. There have been several major factors responsible for our better understanding of the nature and pathophysiology of urinary tract infection. One has been quantitated urine bacteriology and another, the discovery that a significant part of the apparently healthy adult female population has asymptomatic bacteriuria. Abnormal conditions such as neurogenic bladder, bladder malignancy, prolonged catheter drainage and reflux, altered host resistance, diabetes mellitus, and urinary tract obstruction, as well as pregnancy, may either predispose to or be implicated in the pathogenesis of urinary tract infection. There is a wide range of conditions that result in acute renal inflammation and those under discussion affect primarily the interstitium. This term refers to the connective tissue elements separating the tubules in the cortex and medulla. Hence, the interstitial nephritides are to be distinguished from the glomerulonephritides and fall into two general etiologic categories: infectious and noninfectious.

    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.

    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

    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 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.

    Acute renal impairment (ARI) secondary to immersion and near-drowning is rarely described and poorly understood. A retrospective case-control study was performed: (1) to determine the incidence of ARI associated with near-drowning or immersion and (2) to define the clinical syndrome and to assess clinical predictors of ARI. Of 30 patients presenting after immersion or near-drowning, 50% were identified with ARI, with a mean admission serum creatinine of 0.24 +/- 0.33 mmol/L (2.7 +/- 3.7 mg/dl). These patients were a heterogeneous group: Eight had mild reversible ARI, three had ARI related to shock and multisystem failure, two had rhabdomyolysis-related ARI, and two had severe isolated ARI. Two patients required supportive hemodialysis and two died. Patients with ARI experienced more marked acidosis than control patients, as measured by serum bicarbonate (P drowning and is a heterogeneous condition. Although mild reversible renal impairment (serum creatinine drowning or immersion should be assessed for potential ARI by serial estimations of serum creatinine, particularly when there is an increase in the initial serum creatinine, marked metabolic acidosis, an abnormal urinalysis, or a significant lymphocytosis.

    Acute kidney injury (AKI) in the ICU frequently requires costly supportive therapies, has high morbidity, and its long-term prognosis is not as good as it has been presumed so far. Consequently, AKI generates a significant burden for the healthcare system. The problem is that AKI lacks an effective treatment and the best approach relies on early secondary prevention. Therefore, to facilitate early diagnosis, a broader definition of AKI should be established, and a marker with more sensitivity and early-detection capacity than serum creatinine - the most common marker of AKI - should be identified. Fortunately, new classification systems (RIFLE, AKIN or KDIGO) have been developed to solve these problems, and the discovery of new biomarkers for kidney injury will hopefully change the way we approach renal patients. As a first step, the concept of renal failure has changed from being a "static" disease to being a "dynamic process" that requires continuous evaluation of kidney function adapted to the reality of the ICU patient.

    Acute rejection (AR) remains the primary risk factor for renal transplant outcome; development of non-invasive diagnostic biomarkers for AR is an unmet need. We used shotgun proteomics applying LC-MS/MS and ELISA to analyze a set of 92urine samples, from patients with AR, stable grafts (STA), proteinuria (NS), and healthy controls (HC). A total of 1446 urinary proteins were identified along with a number of NS specific, renal transplantation specific and AR specific proteins. Relative abundance of identified urinary proteins was measured by protein-level spectral counts adopting a weighted fold-change statistic, assigning increased weight for more frequently observed proteins. We have identified alterations in a number of specific urinary proteins in AR, primarily relating to MHC antigens, the complement cascade and extra-cellular matrix proteins. A subset of proteins (UMOD, SERPINF1 and CD44), have been further cross-validated by ELISA in an independent set of urine samples, for significant differences in the abundance of these urinary proteins in AR. This label-free, semi-quantitative approach for sampling the urinary proteome in normal and disease states provides a robust and sensitive method for detection of urinary proteins for serial, non-invasive clinical monitoring for graft rejection after kidney transplantation.

    Impaired renal function and anaemia are common among patients with acute myocardial infarction (AMI). While both conditions are known independent risk factors for increased mortality, their interaction as risk factors for increased mortality in AMI is unclear. We studied 5395 subjects hospitalized for AMI between January 2000 and December 2005. An estimated glomerular filtration rate (GFR) Anaemia was defined as anaemia, 1105 (20.5%) patients with impaired GFR without anaemia, 465 (8.6%) patients with preserved GFR and anaemia, and 3012 (55.8%) patients with preserved GFR without anaemia; one-year mortality rates were 56.5%, 41.8%, 31.8% and 10.3% respectively in these 4 groups. Among patients with impaired GFR, anaemia was associated with an adjusted OR of 1.47 (95% CI=1.17-1.85) for one-year mortality, while among patients with preserved GFR, anaemia was associated with a higher adjusted OR of 2.07 (95% CI=1.54-2.76) for one-year mortality, interaction Panaemia confers greater than five-fold increased risk of mortality after AMI. The differential effect of anaemia among patients with impaired and preserved GFR on mortality suggests that in patients with preserved GFR anaemia confers a greater relative hazard than in patients with impaired renal function.

    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. Anticoagulation of the extracorporeal circuit was achieved with systemic heparin in 26 patients; frequent saline flushes were used in the other 24 patients. Results: Of the 50 patients studied, 29 were males and 21 females (1.4:1. The average age was 52.88 years (range: 20-75 years. Causes of ARF included sepsis in 24 (48%, hemodynamically mediated renal failure (HMRF in 18 (36%, and acute over chronic kidney disease in 8 (16% patients. The overall mortality was

    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.

    Rhabdomyolysis contributes to 7-10% of total AKI cases. Myoglobinuria as a cause of acute renal allograft dysfunction is extremely uncommon. Renal allograft recipient on cyclosporine or tacrolimus can develop myoglobinuria in presence of other precipitating factors. Present case describes an interesting report of myoglobinuria in a patient with post transplant diabetic nephropathy mimicking acute graft rejection. Clinically myoglobinuria presenting as renal allograft dysfunction is diagnosis of exclusion and renal biopsy is extremely important in making a correct diagnosis and planning optimal management in such cases.

    Full Text Available A Injúria Renal Aguda (IRA no contexto do paciente politraumatizado ocorre, na maioria das vezes, por uma conjuntura de fatores que passam por eventos correlacionados à ressuscitação volêmica inicial, ao grau de resposta inflamatória sistêmica associada ao trauma, ao uso de contraste iodado para procedimentos diagnósticos, à rabdomiólise e à síndrome compartimental abdominal. Atualmente, passamos por uma fase de uniformização dos critérios diagnósticos da IRA com o Acute Kidney Injury Network (AKIN, sendo a referência mais aceita. Consequentemente, o estudo da IRA no politraumatismo também passa por uma fase de reformulação. Esta revisão da literatura médica visa trazer dados epidemiológicos, fisiológicos e de implicação clínica para o manuseio destes pacientes, bem como expor os riscos do uso indiscriminado de expansores volêmicos e particularidades sobre a instituição de terapia renal substitutiva em indivíduos sob risco de hipertensão intracraniana.Acute Kidney Injury (AKI in trauma is, in most cases, multifactorial. Factors related to the initial ressuscitation protocol, degree of the systemic inflamatory response to trauma, contrast nephropathy in diagnostic procedures, rhabdomyolysis and abdominal compartment syndrome are some of those factors. Nowadays a uniformization in diagnostic criteria for AKI has been proposed by the Acute Kidney Injury Network (AKIN and as a result the incidence of AKI and its impact in outcomes in trauma patients also needs to be reconsider. In this review we aim to approach epidemiologic, physiologic and clinical relevant data in the critical care of patients victims of trauma and also to expose the risks of indiscriminate use of volume expanders and the interaction between renal replacement theraphy and intracranial hypertension.

    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.

Herein, we reported a case of acute appendicitis in a patient with crossed renal ectopia. A 22-year-old man with abdominal pain admitted to the emergency department. His physical examination revealed muscular defense and painful mass at the lower quadrant. Abdominal ultrasonography revealed crossed renal ectopia with no sign of stones and acute appendicitis. Tomography confirmed crossed renal ectopia but not acute appendicitis. On-going clinical symptoms lead to surgical intervention and acute appendicitis diagnosis. The patient was treated with appendectomy with no perioperative complications. Appendectomy is a common surgical procedure in surgical clinical practice. Acute abdominal pain must be managed carefully in patients with unusual anatomy. Also surgeons should be aware of ectopic organs in surgical procedures, to avoid iatrogenic intraoperative injuries.

  8. Trimethoprim-sulfamethoxazole induced acute interstitial nephritis in renal allografts; clinical course and outcome.

    Acute interstitial nephritis (AIN) secondary to trimethoprim-sulfamethoxazole (TMP-SMX) is well documented as a cause of acute renal failure in native kidneys. TMP-SMX is the standard prophylactic agent against pneumocystis carinii (PCP) used in the early post-transplant period, however, it has to date only been indirectly associated with AIN in renal allografts. DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS: We describe eleven renal transplant patients with acute allograft dysfunction in whom a transplant biopsy demonstrated primary histopathologic features of allergic AIN, all of whom were receiving TMP-SMX in addition to other medications known to cause AIN.

    Aristolochic acid nephropathy (AAN) is a progressive kidney disease caused by a Chinese herb containing aristolochic acid. Excessive death of renal tubular epithelial cells (RTECs) characterized the acute phase of AAN. Therapies for acute AAN were limited, such as steroids and angiotensin-receptor blockers (ARBs)/angiotensin-converting enzyme inhibitors (ACEIs). It was interesting that, in acute AAN, female patients showed relative slower progression to renal failure than males. In a previous study, female hormone 17β-estradiol (E2) was found to attenuate renal ischemia-reperfusion injury. Thus, the aim of this study was to investigate the potential protective role of E2 in acute AAN. Compared with male C57BL/6 mice of acute AAN, lower serum creatinine (SCr) and less renal injury, together with RTEC apoptosis in females, were found. Treatment with E2 in male AAN mice reduced SCr levels and attenuated renal tubular injury and RTEC apoptosis. In the mice kidney tissue and human renal proximal tubule cells (HK-2 cells), E2 both attenuated AA-induced cell apoptosis and downregulated the expression of phosphor-p53 (Ser15), p53, and cleaved-caspase-3. This study highlights that E2 exhibited protective effects on the renal injury of acute AAN in male mice by reducing RTEC apoptosis, which might be related to inhibiting the p53 signaling pathway.

    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.

    To investigate Doppler sonographic findings valuable for detecting acute rejection in transplanted kidney with chronic allograft dysfunction. Forty-three renal allografts who underwent renal Doppler sonography and renal biopsy due to chronic allograft dysfunction were included. According to histopathologic findings, patients were classified into 2 groups: chronic component only(group 1, n=30) and acute rejection with or without chronic component 2 groups were performed. No definite difference in radio of renal size, cortical echogenecity, corticomedullary differentiation was noted between group 1 and group 2.Resistive index was 0.61{+-}0.18 in group 1 and 0.64{+-}0.22 in group 2, which showed no statistically significant difference. Characteristic Doppler sonographic findings suggesting acute rejection in cases of chronic allograft dysfunction were not found inauther's study. Therefore, minimal invasive renal biopsy to determine histopathologic status of transplanted kidney is essential in evaluation of the chronic allograft dysfunction

    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.

    Early data are now appearing relating to the measurement of biomarkers of acute kidney injury during renal replacement therapy. These data go some way in describing the clearance of these molecules during renal support. Understanding the potential clearance, or otherwise, of these proteins may lead to directing our therapies in the future particularly with regard to cessation of renal support. We describe a recent study which has provided data that may aid in addressing this issue.

    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.

    At 5:28 a.m. (local time) on December 26, 2003, an earthquake measuring 6.51 on the Richter scale struck the city of Bam in the Kerman Province in southeastern Iran. Among the most important morbid events in survivors were acute renal problems. Clinical findings, laboratory data, and management of the renal victims, all of whom were transferred to Shiraz Hospitals, have been the subject of this analysis. Medical records of twenty patients with acute renal failure admitted to three university hospitals and one community hospital were reviewed. Overall, 801 patients were transferred to Shiraz hospitals, of whom 20 (mean age 36.2 +/- 14.8 years, 15 males) developed acute renal failure with mean duration of 14.5 +/- 9.6 days. Total mortality was 21 (2.6%) and acute renal failure mortality was 3 (15%). Seven patients received standard fluid therapy and 13 patients received variable volume treatment. In total, 79 dialysis sessions were performed in 15 patients (mean 5.2, 3.3 +/- 1 sessions per patients). There was a positive correlation between time spent under rubble and peak serum CK (creatine phosphokinase) level (p = 0.035), acute renal failure duration (p = 0.047), and admission potassium levels (p = 0.033). Serum CK level was positively correlated with acute renal failure duration (p = 0.008). Patients who had received standard treatment had significantly shorter duration of acute renal failure (7.1 versus 9.4 days, p = 0.008) and less need for dialysis (1 versus 6, p = 0.007) than patients who were treated variably. In victims of earthquake, time spent under rubble and peak serum CK level can serve to estimate morbidity, and early standard treatment may decrease renal morbidity.

    2014-02-01

    Autoregulation of glomerular capillary pressure via regulation of the resistances at the afferent and efferent arterioles plays a critical role in maintaining the glomerular filtration rate over a wide range of mean arterial pressure. Angiotensin II and prostaglandins are among the agents which contribute to autoregulation and drugs which interfere with these agents may have a substantial impact on afferent and efferent arteriolar resistance. We describe a patient who suffered an episode of anuric acute kidney injury following exposure to a nonsteroidal anti-inflammatory agent while on two diuretics, an angiotensin-converting enzyme inhibitor, and an angiotensin receptor blocker. The episode completely resolved and we review some of the mechanisms by which these events may have taken place and suggest the term "acute renal autoregulatory dysfunction" to describe this syndrome.

    Compartment syndrome of the thigh is a rare emergency often treated operatively. The purpose of this study was to evaluate the effects of nonoperative treatment for compartment syndrome of the thigh associated with acute renal failure after the 2008 Wenchuan earthquake. Nonoperative treatment, which primarily involves continuous renal replacement therapy, was performed in 6 patients (3 men and 3 women) who presented with compartment syndrome of the thigh associated with acute renal failure. The mean mangled extremity severity score (MESS) and laboratory data regarding renal function were analyzed before and after treatment, and the clinical outcome was evaluated at 17-month follow-up. Laboratory data regarding renal function showed improvements. All 6 patients survived with the affected lower limbs intact after nonoperative treatment. Follow-up revealed active knee range of motion and increased muscle strength, as well as a recovery of sensation. A positive linear correlation was found between MESS and the time required to achieve a reduction in swelling, as well as the time required for the recovery of sensation and knee range of motion (r>0.8; P<.05). Satisfactory clinical outcomes were obtained in patients with compartment syndrome of the thigh associated with acute renal failure.Urine alkalization, electrolyte and water balance, and continuous renal replacement therapy have played an important role in saving lives and extremities. Nonoperative treatment should be considered in the treatment of compartment syndrome of the thigh associated with acute renal failure.

    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

    Plasmodium ovale is one of the causative agents of human malaria. Plasmodium ovale infection has long been thought to be non-fatal. Due to its lower morbidity, P. ovale receives little attention in malaria research. Two Malaysians went to Nigeria for two weeks. After returning to Malaysia, they fell sick and were admitted to different hospitals. Plasmodium ovale parasites were identified from blood smears of these patients. The species identification was further confirmed with nested PCR. One of them was successfully treated with no incident of relapse within 12-month medical follow-up. The other patient came down with malaria-induced respiratory complication during the course of treatment. Although parasites were cleared off the circulation, the patient's condition worsened. He succumbed to multiple complications including acute respiratory distress syndrome and acute renal failure. Sequencing of the malaria parasite DNA from both cases, followed by multiple sequence alignment and phylogenetic tree construction suggested that the causative agent for both malaria cases was P. ovale curtisi. In this report, the differences between both cases were discussed, and the potential capability of P. ovale in causing severe complications and death as seen in this case report was highlighted. Plasmodium ovale is potentially capable of causing severe complications, if not death. Complete travel and clinical history of malaria patient are vital for successful diagnoses and treatment. Monitoring of respiratory and renal function of malaria patients, regardless of the species of malaria parasites involved is crucial during the course of hospital admission.

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

    Science.gov (United States)

    Ishikawa, Isao

    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

    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.

    2014-01-01

    The RIFLE and AKIN criteria have definitely help out to draw attention to the relationship between a deterioration of renal function that produces a small increase in serum creatinine and a worse outcome. However, the specific clinical utility of using these criteria remains to be well-defined. It is believed that the main use of these criteria is for the design of epidemiological studies and clinical trials to define inclusion criteria and objectives of an intervention. AKI adopting term, re-summoning former ARF terminology, it is appropriate to describe the clinical condition characterized by damage to kidney, in the same way as the term is used to describe acute lung damage where the lung injury situation still has not increased to a situation of organ failure (dysfunction). The serum and urine biomarkers (creatinine, urea, and diuresis) currently in use are not sensitive or specific for detecting kidney damage, limiting treatment options and potentially compromising the outcome. New biomarkers are being studied in order to diagnose an earlier and more specific AKI, with the potential to change the definition criteria of AKI with different stages, currently based in diuresis and serum creatinine.

    Full Text Available Aim: The aim of this study was to investigate the etiological factors, clinical progression and management of acute renal failure (ARF in hospitalized children. Materials and Method: Medical records of 63 patients aged between 1 month and 18 years who were hospitalized at Uludag University, Department of Pediatrics or at various intensive care departments of the faculty and diagnosed with ARF between January 2005 and August 2006 were retrospectively analyzed. Results: Forty two of study patients were male and 21 were female. Mean age was 5.4±5.3 years. ARF was found in 4.9% of all hospitalized patients. Sepsis was the most frequent etiological factor with a ratio of 23.8%; which was followed by gastroenteritis (19.1%, tumor lysis syndrome (17.4% and cardiac surgery (15.9%. Oliguria, sepsis, hyperkalemia, acidosis and dialysis were found to be associated with increased mortality (p<0.05.

    Renal dysfunction is a frequent finding in patients with acute heart failure (AHF) and an important prognostic factor for adverse outcomes. Worsening of renal function occurs in 30-50% of patients hospitalised for AHF, and is associated with increased mortality, prolonged hospital stay and increased risk of readmission. Likely mechanisms involved in the decrease in renal function include impaired haemodynamics and activation of neurohormonal factors, such as the renin-angiotensin-aldosterone system, the sympathetic nervous system and the arginine-vasopressin system. Additionally, many drugs currently used to treat AHF have a detrimental effect on renal function. Therefore, pharmacotherapy for AHF should carefully take into account any potential complications related to renal function. Serelaxin, currently in clinical development for the treatment of AHF is a recombinant form of human relaxin-2, identical in structure to the naturally occurring human relaxin-2 peptide hormone that mediates cardiac and renal adaptations during pregnancy. Data from both pre-clinical and clinical studies indicate a potentially beneficial effect of serelaxin on kidney function. In this review, we discuss the mechanisms and impact of impairment of renal function in AHF, and the potential benefits of new therapies, such as serelaxin, in this context.

    Postinfectious proliferative glomerulonephritis may occur in HIV-infected patients, although it is not a common cause of severe acute renal failure in them. We report a woman with HIV infection, who developed hypocomplementemic acute nephritic syndrome 10 days after an upper respiratory infection. Systemic diseases were excluded. The serum creatinine level increased to 6.6 mg/dl. Renal biopsy showed diffuse endocapillary proliferative glomerulonephritis, with mesangial and capillary walls, granular deposits of IgG and C3 by immunofluorescence. She was given corticosteroids with progressive normalization of her renal function. No opportunistic infections have occurred during 1-year follow-up.

    Full Text Available The article focuses on the results of the investigation of peripheral blood lymphocyte morphofunctional status in healthy volunteers and renal allograft recipients for early postoperative period. Working out noninvasive tests for diagnosis of acute renal allograft rejection based on the measuring of cell morphometric parameters by method of coherent phase microscopy (CPM. It was found out that the lymphocyte phase height was proportional cell image density and its geometrical thickness. Our results showed that the variations of immunocompetent cell morphometric indicants can be in advance the dynamics of blood creatine increasing and answer for early criteria of acute renal allograft rejection.

    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.

    Full Text Available Glutaric Aciduria type I (GA-I is a rare organic acidemia, caused by mutations in the GCDH gene, and characterized by encephalopathic crises with neurological sequelae. We report herein a patient with GA-I who presented with severe acute renal failure requiring dialysis, following an acute diarrheal illness. Histopathological evaluation demonstrated acute tubular necrosis, and molecular diagnosis revealed the patient to be homozygous for a previously unreported mutation, p.E64D. As renal impairment is not part of the clinical spectrum typical to GA-I, possible associations of renal failure and the underlying inborn error of metabolism are discussed, including recent advancements made in the understanding of the renal transport of glutaric acid and its derivatives during metabolic disturbance in GA-I.

    When imaging a renal transplant, the combination of absent flow in the main renal vein and reversed diastolic flow in the intrarenal arteries is considered highly suggestive of renal vein thrombosis. We present a case of torsion of a transplant kidney presenting with identical findings. Renal transplant torsion in general is a rare entity, previously described only in intraperitoneally placed organs; this case is the first that we are aware of with torsion occurring in a retroperitoneally placed graft.

  4. Acute hepatic ischemic-reperfusion injury induces a renal cortical "stress response," renal "cytoresistance," and an endotoxin hyperresponsive state.

    Hepatic ischemic-reperfusion injury (HIRI) is considered a risk factor for clinical acute kidney injury (AKI). However, HIRI's impact on renal tubular cell homeostasis and subsequent injury responses remain ill-defined. To explore this issue, 30-45 min of partial HIRI was induced in CD-1 mice. Sham-operated or normal mice served as controls. Renal changes and superimposed injury responses (glycerol-induced AKI; endotoxemia) were assessed 2-18 h later. HIRI induced mild azotemia (blood urea nitrogen ∼45 mg/dl) in the absence of renal histologic injury or proteinuria, implying a "prerenal" state. However, marked renal cortical, and isolated proximal tubule, cytoprotective "stress protein" gene induction (neutrophil gelatinase-associated lipocalin, heme oxygenase-1, hemopexin, hepcidin), and increased Toll-like receptor 4 (TLR4) expression resulted (protein/mRNA levels). Ischemia caused release of hepatic heme-based proteins (e.g., cytochrome c) into the circulation. This corresponded with renal cortical oxidant stress (malondialdehyde increases). That hepatic derived factors can evoke redox-sensitive "stress protein" induction was implied by the following: peritoneal dialysate from HIRI mice, soluble hepatic extract, or exogenous cytochrome c each induced the above stress protein(s) either in vivo or in cultured tubule cells. Functional significance of HIRI-induced renal "preconditioning" was indicated by the following: 1) HIRI conferred virtually complete morphologic protection against glycerol-induced AKI (in the absence of hyperbilirubinemia) and 2) HIRI-induced TLR4 upregulation led to a renal endotoxin hyperresponsive state (excess TNF-α/MCP-1 gene induction). In conclusion, HIRI can evoke "renal preconditioning," likely due, in part, to hepatic release of pro-oxidant factors (e.g., cytochrome c) into the systemic circulation. The resulting renal changes can impact subsequent AKI susceptibility and TLR4 pathway-mediated stress.

    Acute kidney injury (AKI) is a very common complication after allogeneic bone marrow transplantation (BMT) and associated with poor prognosis. Generally kidneys are assumed to be no direct target of Graft-versus-Host Disease (GvHD), and renal impairment is often attributed to several other factors occurring in the early phase after BMT. Our study aimed to prove the existence of renal GvHD in a fully MHC-mismatched model of BALB/c mice conditioned and transplanted according to two different intensity protocols. Syngeneically transplanted and untreated animals served as controls. 4 weeks after transplantation, allogeneic animals developed acute GvHD that was more pronounced in the high-intensity protocol (HIP) group than in the low-intensity protocol (LIP) group. Urea and creatinine as classic serum markers of renal function could not verify renal impairment 4 weeks after BMT. Creatinine levels were even reduced as a result of catabolic metabolism and loss of muscle mass due to acute GvHD. Proteinuria, albuminuria, and urinary N-acetyl-beta-Dglucosaminidase (NAG) levels were measured as additional renal markers before and after transplantation. Albuminuria and NAG were only significantly increased after allogeneic transplantation, correlating with disease severity between HIP and LIP animals. Histological investigations of the kidneys showed renal infiltration of T-cells and macrophages with endarteriitis, interstitial nephritis, tubulitis, and glomerulitis. T-cells consisted of CD4+, CD8+, and FoxP3+ cells. Renal expression analysis of allogeneic animals showed increases in indoleamine-2,3 dioxygenase (IDO), different cytokines (TNFα, IFN-γ, IL-1α, IL2, IL-6, and IL-10), and adhesion molecules (ICAM-1 and VCAM-1), resembling findings from other tissues in acute GvHD. In summary, our study supports the entity of renal GvHD with histological features suggestive of cell-mediated renal injury. Albuminuria and urinary NAG levels may serve as early markers of renal

    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. This is due to the increasing and earlier use of extrarenal depuration techniques. Modifications in nutritional and metabolic support regimen aimed at preventing renal failure progression, classically recommended, would not have an indication in these situations but in cases not treated with one of these depurative techniques. Thus, protein intake should be

    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.

    The acute Page kidney phenomenon occurs as a consequence of external compression of the renal parenchyma leading to renal ischemia and hypertension. Between January 2000 and September 2007, 550 kidney transplants and 518 ultrasound-guided kidney biopsies were performed. During that time, four recipients developed acute oligo-anuria following ultrasound-guided allograft biopsy. Emergent doppler-ultrasounds were performed demonstrating absence of diastolic flow as well as a sub-capsular hematoma of the kidney. Prompt surgical exploration with allograft capsulotomy was performed in all cases. Immediately after capsulotomy, intraoperative Doppler study demonstrated robust return of diastolic flow. Three patients maintained good graft function, and one kidney was lost due to acute antibody-mediated rejection. We conclude that postbiopsy anuria associated with a subcapsular hematoma and acute absence of diastolic flow on doppler ultrasound should be considered pathognomonic of APK. All renal transplant specialists should be able to recognize this complication, because immediate surgical decompression can salvage the allograft.

    Over a million patients get hospitalized with the diagnosis of acute decompensated heart failure which poses an insurmountable financial burden on the health care system. Heart failure alone incurs over 30 billion dollars with half the cost spent towards acute hospitalizations. Majority of the treatment strategies have focused towards decongesting patients which often comes with the cost of worsening renal function. Renal dysfunction in the setting of acute decompensated heart failure portends worse morbidity and mortality. Recently, there has been a change in the focus with shift towards therapies attempting to conserve renal function. In the past decade, we have witnessed several large randomized controlled trials testing the established as well as emerging therapies in this subset of population with mixed results. This review intends to provide a comprehensive overview of the pharmacologic therapies commonly utilized in the management of acute decompensated heart failure and the body of evidence supporting these strategies.

  14. The management of neonatal acute and chronic renal failure: A review.

    Most babies with chronic renal failure are identified antenatally, and over half that are treated with peritoneal dialysis receive kidney transplants before school age. Most infants that develop acute renal failure have hypotension following cardiac surgery, or multiple organ failure. Sometimes the falls in glomerular filtration and urine output are physiological and reversible, and sometimes due to kidney injury, but (illogically) it is now common to define them all as having 'acute kidney injury'. Contrary to widespread opinion, careful interpretation of the plasma creatinine concentrations can provide sensitive evidence of early acute renal failure. Conservative management frequently leads to under-nutrition or fluid overload. Acute peritoneal dialysis is often technically fraught in very small patients, and haemotherapies have been limited by vascular access and anticoagulation requirements, the need to blood-prime circuits, and serious limitations in regulating fluid removal. Newer devices, including the Nidus, have been specifically designed to reduce these difficulties.

    The objective of this study was to determine the risk factors of postoperative acute renal failure (ARF) in orthotopic liver transplantation (OLT). We reviewed 184 consecutive OLT. Postoperative ARF was defined as a persistent rise of 50% increase or more of the S-creatinine (S-Cr). The patients were classified as early postoperative ARF (E-ARF) (first week) and late postoperative ARF (L-ARF) (second to fourth week). Preoperative variables were age, sex, comorbidity, indication for OLT, Child-Pugh stage, united network for organ sharing status, analysis of the blood and urine, and donor's data. Intraoperative variables were systolic arterial pressure, mean arterial pressure, pulmonary capillary wedge pressure, cardiac index, and systemic vascular resistance index. Surgical technique, number of blood products transfused, need for adrenergic agonist drugs, and intraoperative complications were also important. Postoperative variables were duration of stay in the intensive care unit, time on mechanic ventilation, liver graft dysfunction, need for adrenergic agonist drugs, units of blood products infused, episodes of acute rejection, re-operations, and bacterial infections. Firstly we carried out a univariate statistical analysis, and secondly a logistic regression analysis. The risk factors for E-ARF were: pretransplant ARF (odds ratio (OR)=10.2, P=0.025), S-albumin (OR=0.3, P=0.001), duration of treatment with dopamine (OR=1.6, P=0.001), and grade II-IV dysfunction of the liver graft (OR=5.6, P=0.002). The risk factors for L-ARF were: re-operation (OR=3.1, P=0.013) and bacterial infection (OR=2.9, P=0.017). The development of E-ARF is influenced by preoperative factors such as ARF and hypoalbuminemia, as well as postoperative factors such as liver dysfunction and prolonged treatment with dopamine. The predicting factors of L-ARF differ from E-ARF and correspond to postoperative causes such as bacterial infection and surgical re-operation.

    2014-09-01

    Full Text Available OBJECTIVE: Colistin is a polymyxin antibiotic with a polypeptide structure and is effective against gram-negative bacilli. Although its use had decreased due to its side effects, it has increased again in recent years, especially for multi-drug resistant Pseudomonas aeruginosa, Klebsiella pneumoniae, Acinetobacter and Enterobacteriaceae. In the present study, patients that received colistin at one center were retrospectively analysed in terms of nephrotoxicity. MATERIAL and METHODS: Patients hospitalized and treated with colistin in the intensive care unit between January 2012 and August 2013 were analyzed. Demographic data; biochemical tests at baseline, daily during hospitalization and after discharge; and the initial, maintenance and total doses of colistin were evaluated. RESULTS: The mean age was 62±13 (31-86 years for the 27 patients with 17 (63% males that were followed-up for an average duration of 63±89 days. During follow-up, 18 patients (66.7% developed acute renal failure (ARF and 17 (63% of died. There were 12 (66.7% mortalities in the ARF group and 5 (55% in the group without ARF ( p> 0.05. The total colistin dose and leukocyte count were higher in the ARF group with 3.75±2.34 g and 12.04±5.05/mm3 than the non-ARF group at 3.32±1.86 g and 7.60±3.7/mm3 but did not reach statistical significance. CONCLUSION: ARF increases the mortality in ICU patients. Although colistin is an effective therapeutic agent used for resistant infections, we have to avoid higher doses due to its potential side effect of ARF.

    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.

  19. The value of urine cytologic examination findings in the diagnosis of the acute renal allograft rejection

    Directory of Open Access Journals (Sweden)

    Tatomirović Željka

    2003-01-01

    Full Text Available Background. Acute rejection of allograft is one of the most serious complications of renal transplantation that requires fast and precise diagnostic approach. In this paper our experience in cytologic urinalysis as a diagnostic method of the acute renal allograft rejection was reviewed. Methods. The study group included 20 of 56 patients with transplanted kidneys who were assumed for the acute allograft rejection according to allograft dysfunction and/or urine cytology findings. Histological findings confirmed allograft rejection in 4 patients. Urine sediment obtained in cytocentrifuge was air-dried and stained with May-Grunwald-Giemsa. Acute allograft rejection was suspected if in 10 fields under high magnification 15 or more lymphocytes with renal tubular cells were found. Results. Acute transplant rejection occured in 32.1% patients. In 15 patients clinical findings of the acute renal allograft rejection corresponded with cytological and histological findings (in the cases in which it was performed. Three patients with clinical signs of the acute allograft rejection were without cytological confirmation, and in 2 patients cytological findings pointed to the acute rejection, but allograft dysfunction was of different etiology (acute tubular necrosis, cyclosporine nephrotoxicity. In patients with clinical, cytological and histological findings of the acute allograft rejection urine finding consisted of 58% lymphocytes, 34% neutrophilic leucocytes and 8% monocytes/macrophages on the average. The accuracy of cytologic urinalysis related to clinical and histological finding was 75%. Conclusion. Urine cytology as the reliable noninvasive, fast and simple method is appropriate as the a first diagnostic line of renal allograft dysfunction, as well as for monitoring of the graft function.

    Patients with acute pyleonephritis may present with a spectrum of clinical symptoms and signs. There are few noninvasive diagnostic studies, however to confirm or exclude this diagnosis. To evaluate the clinical utility of {sup 99m}Tc-DMSA renal scan in diagnosis of acute pyelonephritis, we performed {sup 99m}Tc-DMSA renal scan in 37 patients suspected with urinary tract infection. Simultaneously kidney ultrasonography was done in 21 patients diagnosed with acute pyelonephritis, clinically. And we performed the followup scan after treatment in two to six weeks. The results were as follows. 1) {sup 99m}Tc-DMSA renal scan disclosed single of multiple cortical defects and decreased radiouptake ratio of affected kidney in 23 patients among 25 patients diagnosed with acute pyleonephritis. 2) In the 21 patients with acute pyelonephritis, kidney ultrasonography showed abnormal findings in the 7 patients. And {sup 99m}Tc-DMSA renal scan disclosed abnormal cortical defects in this 7 patients also. 3) Between the patients with acute pyelonephritis and those with lower urinary tract infection, asymptomatic bacteriuria or pyuria, right-to-left radiouptake ratios (R/L ratio ) were significantly different(p<0.001). 4) In two to six weeks after antibiotic therapy, we performed followup {sup 99m}Tc-DMSA renal scan for 5 patients among 25 acute pyelonephritis patients. And we have found the improvement of cortical defects and the right-to-left radiouptake ratio. In conclusion, we thought that {sup 99m}Tc-DMSA renal scan should be useful in diagnosis of acute pyelonephritis and follow up examination.

    The term Acute Renal Failure (ARF) has been replaced by the term Acute Kidney Injury (AKI). AKI indicates an abrupt (within 24-48h) decrease in Glomerular Filtraton Rate, due to renal damage, that causes fluid and metabolic waste retention and alteration of electrolyte and acid-base balance. The renal biomarkers of AKI are substances or processes that are indicators of normal or impaired function of the kidney. The most used renal biomarker is still serum creatinine that is inadequate for several reasons, one of which is its inability to differentiate between hemodynamic changes of renal function ("prerenal azotemia") from intrinsic renal failure or obstructive nephropathy. Cystatin C is no better in this respect. After the description of the pathophysiology of "prerenal azotemia" and of Acute Kidney Injury (AKI) due to ischemia or nephrotoxicity, the renal biomarkers are listed and described: urinary NAG, urinary and serum KIM-1, serum and urinary NGAL, urinary IL-18, urinary L-FABP, serum Midkine, urinary IGFBP7 and TIMP2, urinary α-GST and π-GST, urinary ɣGT and AP, urinary β2M, urinary RBP, serum and urinary miRNA. All have been shown to appear much earlier than the rise of serum Creatinine. Some of them have been demonstrated to predict the clinical outcomes of AKI, such as the need for initiation of dialysis and mortality.

    Acute renal injury is a common severe clinical syndrome, occurring in many clinical situations. It is necessary to explore effective drugs to treat it. Eupafolin is a flavonoid compound, derived from Phyla nodiflora, which has been previously reported to possess a variety of pharmacological activities, including anti-inflammatory and antioxidant effects. However, it is known little about how it works in acute renal injury. Also, eupafolin is characterized by skin penetration and poor water solubility, limiting its clinical applications. Thus, we synthesized an eupafolin nanoparticle delivery system. We found that eupafolin nanoparticle could address the physicochemical defects of raw eupafolin and increase water solubility without any toxicity to normal renal cells via reducing particle size. Eupafolin nanoparticle attenuated LPS-induced acute renal injury in mice through inhibiting oxidative stress and inflammation accompanied with up-regulated SOD activity and down-regulated pro-inflammatory cytokines. Additionally, inactivation of NF-κB and MAPKs of p38, ERK1/2 and JNK signaling pathways was a main molecular mechanism by which eupafolin nanoparticle improved renal injury. Together, eupafolin nanoparticle exhibits effective anti-oxidant and anti-inflammatory activities, which could be used as a potential drug to ameliorate acute renal injury clinically.

    Objectives Recently, several authors reported that Tc-99m DMSA renal scan frequently showed cortical defects of the involved kidneys even in the patients with acute pyelonephritis who did not show abnormal findings in the ultrasonography and intravenous pyelography IVP). Methods In order to evaluate the utilities of Tc-99m DMSA renal scan and the clinical meanig of cortical defects in the Tc-99m DMSA renal scan of the patients with acute pyelonephritis, ninety two patients with acute pyelonephritis, from March 1991 to February 1994 in Chungnam National University Hospital(CNUH), were included in this study. Patients were subdivided as Group A:Patients showing normal Tc-99m DMSA renal scan(n=42) and Group B:Patients with definit cortical defects on the Tc-99m DMSA renal scan(n=50). We compared clinical characteristics such as age and sex, recurrency, duration of fever, bacterial culture study, incidence of renal insufficiency and the results of renal ultrasonography and intravenous pyelography between the two groups. Results Fifty four percents of 92 patients with acute pyelonephritis showed a significantly longer febrile period after admission, higher positive rates on the urine and blood culture studies and higher incidence of renal insufficiency than those of the Group A patients. Sixty nine percents of Group B patients showed normal results in ultrasonography or IVP study. Conclusions Tc-99m DMSA renal scan was a more sensitive imaging test than ultrasonography in kidneys and IVP to detect pyelonephritis lesions and may be useful to predict the patient group with a severe disease course. These patients may need more careful management and further studies to evaluate the possibility of complications. PMID:7626556

    Introduction: Splenic and renal infarctions are usually related to vascular disease or haematologic abnormalities. Their association is infrequent and rarely observed in trauma. In this study, we analyze our data to look at the occurrence of renal and splenic infarctions based on CT findings in a period of 4 years. Materials and Methods: We retrospectively reviewed the imaging findings of 84 patients admitted to our Department of Diagnostic Imaging from June 1998 to December 2002, who underwent emergency abdominal spiral CT examination and in whom there was evidence of splenic and/or renal infarction. Results: We found 40 cases of splenic infarction and 54 cases of renal infarction, associated in 10 patients. In 26 patients, there was also evidence of intestinal infarction. A traumatic origin was found in 19 cases; non-traumatic causes were found in 65 patients. Association between renal and splenic infarction in the same patient was related to trauma in two cases. Conclusions: Although renal and splenic infarctions are a common manifestation of cardiac thromboembolism, other systemic pathologies, infections or trauma may lead to this occurrence. Renal infarction may be clinically and/or surgically managed with success in most cases. There are potential complications in splenic infarction, such as development of pseudocysts, abscesses, hemorrhage, subcapsular haematoma or splenic rupture; splenectomy in these cases may be necessary. Some patients with splenic and/or renal infarction may be clinically asymptomatic. The high accuracy of CT examination is needed to allow a correct evaluation of infarcted organs.

    Renal zygomycosis, caused by invasive fungi, is a rare and potentially fatal infection. The patient usually presents with non-specific symptoms and renal failure. A 34-year-old male non-diabetic and without any predisposing factors for systemic fungal infection presented to the emergency department with diffuse abdominal pain, high-grade fever and acute renal failure with a serum creatinine of 6.5. A computed tomography showed bilateral diffuse globular nephromegaly. A urine smear for fungal examination showed right angle branching hyphae and kidney biopsy showed fungal hyphae within the glomeruli, tubules and interstitium. Although radiological investigations can give us a clue, the definitive diagnosis can only be made by kidney biopsy. A high index of suspicion and timely diagnosis is important for a proper management.

    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

    Acute interstitial nephritis is a well-recognized cause of acute kidney injury in native kidneys. While the most common etiology being drug-induced, other causes are infectious, autoimmune, and idiopathic forms of disease. Drug-induced acute interstitial nephritis is not only uncommon in renal transplant recipients but is difficult to diagnose as it mimics acute cellular rejection histologically. We have described herein a renal transplant recipient with acute kidney injury to highlight the difficulties to distinguish acute interstitial nephritis from acute cellular rejection.

Relatamos aqui o caso de uma paciente de 47 anos, branca, internada em uma unidade de emergência de Hospital Universitário, devido a sintomas e achados radiológicos sugestivos de pneumonia. Desde o início da internação ela se apresentava com quadro laboratorial de insuficiência renal aguda, inicialmente atribuída ao histórico recente de uso abusivo de anti-inflamatórios. No entanto, devido à evolução arrastada e aparentemente desfavorável, inclusive com necessidade de terapia renal substitutiva (TRS, a paciente foi submetida a uma biópsia renal para esclarecimento diagnóstico e avaliação prognóstica. A descrição histológica mostrava um quadro de nefrite intersticial aguda granulomatosa, característico de sarcoidose renal, diagnóstico confirmado após revisão do prontuário médico, que revelava internação anterior devido a evento pulmonar da doença. Iniciado tratamento com prednisona 1 mg/kg/dia, a paciente evoluiu com melhora do quadro de insuficiência renal aguda, não mais necessitando de TRS. Atualmente, a paciente é mantida em acompanhamento ambulatorial com função renal estável.Sarcoidosis is a systemic disease of unknown etiology, characterized by chronic granulomatous inflammation, which affects most frequently the lungs, skin, and eyes, and most rarely the kidneys.

    Full Text Available Within the first week of the disease, acute kidney injury (AKI is among the most common causes of mortality in acute pancreatitis (AP. Recently, serum angiopoietin-2 (Ang-2 has been associated with hyperdynamic state of the systemic circulation. The aim of this study was to examine the associations between Ang-2 and the clinical AP severity during the first 72 hours of the disease, and organ disfunction, including AKI. Methods. Study included patients admitted to the surgery ward, diagnosed with AP. AKI was diagnosed according to KDIGO guidelines and renal failure according to modified Marshall scoring system. Ang-2 was determined in serum with ELISA. Results. AP was classified as mild (MAP in 71% of patients, moderately severe (MSAP in 22%, and severe (SAP in 8%. During the first 72 hours of AP, 11 patients developed AKI and 6 developed renal failure. Ang-2 at 24, 48, and 72 hours following the onset of AP symptoms significantly predicted SAP and MSAP, as well as AKI and renal failure. Also, Ang-2 significantly correlated with acute phase proteins as well as with the indicators of renal disfunction. Conclusions. Serum Ang-2 may be a relevant predictor of AP severity, in particular of the development of AP-renal syndrome.

    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.

    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.

  16. ACUTE RENAL FAILURE WITH NORMAL PLASMA UREA LEVEL SECONDARY TO ACUTE PYELONEPHITIS IN A SINGLE KIDNEY PATIENT

    2007-04-01

    Full Text Available SUMMARY: Acute renal failure is a syndrome that usually runs with an increase in creatinine and urea plasma levels. However, there are clinical situations in which this syndrome may run with an increase in plasma creatinine keeping normal the urea one. In this report we present a case of acute renal failure with normal plasma urea level secondary to an acute pyelonephritis in a single kidney patient. The patient had an increased fractional excretion of urea which could explain the normal plasma urea levels found despite of his reduced glomerular filtration. This increased urea excretion state was interpreted as a consequence of the nephrogenic diabetes insipidus and alteration of the intra-renal urea reciclying process that the acute pyelonephritis induced. In conclusion: Acute pyelonephritis in a single kidney patient can appear as a pattern of acute renal failure with normal plasma urea levels.RESUMEN: La insuficiencia renal aguda es un sindrome que característicamente cursa con niveles plasmáticos elevados de urea y creatinina. Sin embargo, hay situaciones clínicas en las cuales este sindrome puede cursar con un incremento de la creatininemia sin presentar elevación de la uremia. En este reporte presentamos un caso clínico de una insuficiencia renal aguda con uremia normal secundaria a una pielonefritis aguda en un paciente con riñón único. El paciente presentaba una elevada excreción fraccional de urea lo cual podía explicar su uremia normal pese a estar cursando una caída del filtrado gomerular. Dicha excreción de urea elevada fue interpretada como secundaria a una diabetes insipida nefrogénica y una alteración en el recirculado intra-renal de la urea ambos producto de la pielonefritis aguda. Concluimos que la pielonefritis aguda en un paciente mono-reno puede presentarse con un patrón de insuficiencia renal aguda con uremia normal.

    Over 12 months, urine samples were systematically collected from 40 children who underwent renal transplantation for the treatment of end-stage renal disease. Sequential determinations of the excretion of individual amino acids relative to that of creatinine were carried out on 15 subjects. Nine of these (including three who sustained episodes of acute rejection) retained a native kidney in-situ, while in six patients (including three who underwent an episode of acute rejection) both native kidneys had been removed. In both subgroups, the amino acid/creatinine ratios of early morning urine samples were higher shortly before clinical manifestations of acute rejection became evident than in patients who, following renal transplantation, had stable kidney function, chronic graft rejection, or acute tubular necrosis, with one exception: a patient with one native kidney in-situ in whom acute tubular necrosis developed immediately after transplantation. The amino acids showing the greatest increase included Thr, Ser, Gly, and Ala. These values fell dramatically immediately prior to the clinical episode of acute rejection, with Thr, Ala, and Phe showing the most consistent changes. These alterations in urinary amino acid excretion occurred several days before changes in urinary protein excretion or the serum concentrations of urea and creatinine, and may have a role to play in the monitoring of renal transplant recipients.

    Sunitinib is a multiple tyrosine kinase receptors inhibitor that is approved for the treatment of advanced renal cell carcinoma. Amongst its targets are fetal liver tyrosine kinase receptor 3 (FLT 3) and vascular endothelial growth factor receptor (VEGFR). Renal toxicity has not been reported from the trials, but several patients have been reported to develop a pre-eclampsia-like syndrome. We report the first case of acute tubular necrosis in a patient with multiple myeloma following treatment with sunitinib.

  2. Power doppler sonography in early renal transplantation: Does it differentiate acute graft rejection from acute tubular necrosis?

    2014-01-01

    Full Text Available To evaluate the role of power Doppler in the identification and differentiation bet-ween acute renal transplant rejection and acute tubular necrosis (ATN, we studied 67 live donor renal transplant recipients. All patients were examined by spectral and power Doppler sono-graphy. Assessment of cortical perfusion (CP by power Doppler was subjective, using our grading score system: P0 (normal CP; homogenous cortical blush extending to the capsule, P1 (reduced CP; cortical vascular cut-off at interlobular level, P2 (markedly reduced CP; scattered cortical color flow at the interlobar level. Renal biopsies were performed during acute graft dysfunction. Pathological diagnoses were based on Banff classification 1997. The Mann- Whitney test was used to test the difference between CP grades with respect to serum creatinine (SCr, and resistive index (RI. For 38 episodes of acute graft rejection grade I, power Doppler showed that CP was P1 and RI ranging from 0.78 to 0.89. For 21 episodes of acute graft rejection grade II, power Doppler showed that CP was P1, with RI ranging from 0.88 to >1. Only one case of grade III rejection had a CP of P2. Twelve biopsies of ATN had CP of P0 and RI ranging from 0.80 to 0.89 There was a statistically significant correlation between CP grading and SCr (P <0.01 as well as between CP grading and RI (P <0.05. CP grading had a higher sensitivity in the detection of early acute rejection compared with RI and cross-sectional area measurements. We conclude that power Doppler is a non-invasive sensitive technique that may help in the detection and differentiation between acute renal transplant rejection and ATN, particularly in the early post-transplantation period.

    A 58-year-old man was admitted to our hospital. Laboratory data showed severe liver injury and that the patient was positive for immunoglobulin M anti-hepatitis A virus (HAV) antibodies. He was also complicated with severe renal dysfunction and had an extremely high level of serum hepatocyte growth factor (HGF). 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.

    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.

    Increasing evidence demonstrates that reactive oxygen species plays important roles in sepsis-induced acute kidney injury. This study investigated the effects of VitD3 pretreatment on renal oxidative stress in sepsis-induced acute kidney injury. Mice were intraperitoneally injected with lipopolysaccharide (LPS, 2.0mg/kg) to establish an animal model of sepsis-induced acute kidney injury. In VitD3+LPS group, mice were orally pretreated with three doses of VitD3 (25 μg/kg) at 1, 24 and 48 h before LPS injection. As expected, oral pretreatment with three daily recommended doses of VitD3 markedly elevated serum 25(OH)D concentration and efficiently activated renal VDR signaling. Interestingly, LPS-induced renal GSH depletion and lipid peroxidation were markedly alleviated in VitD3-pretreated mice. LPS-induced serum and renal nitric oxide (NO) production was obviously suppressed by VitD3 pretreatment. In addition, LPS-induced renal protein nitration, as determined by 3-nitrotyrosine residue, was obviously attenuated by VitD3 pretreatment. Further analysis showed that LPS-induced up-regulation of renal inducible nitric oxide synthase (inos) was repressed in VitD3-pretreated mice. LPS-induced up-regulation of renal p47phox and gp91phox, two NADPH oxidase subunits, were normalized by VitD3 pretreatment. In addition, LPS-induced down-regulation of renal superoxide dismutase (sod) 1 and sod2, two antioxidant enzyme genes, was reversed in VitD3-pretreated mice. Finally, LPS-induced tubular epithelial cell apoptosis, as determined by TUNEL, was alleviated by VitD3 pretreatment. Taken together, these results suggest that VitD3 pretreatment alleviates LPS-induced renal oxidative stress through regulating oxidant and antioxidant enzyme genes.

    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.

    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.

    Management of acute renal artery occlusion in patients with a solitary kidney has a poorly defined prognosis. Loss of renal function is reported by some when acute warm ischemia reaches 2 hours. We report a unique case of a patient that had a 24-hour onset of anuria and acute renal failure upon arrival to the hospital. Nuclear imaging showed trace uptake of the right kidney, without evidence of excretion. Conventional digital subtraction angiography was performed; however, evidence of nephrogram or distal filling of the renal artery was not demonstrated. Secondary to conflicting studies, a computed tomography of the abdomen and pelvis with intravenous contrast revealed only minimal cortical perfusion despite complete occlusion of the previously grafted right renal artery. Patient was taken for urgent hepatorenal bypass surgery. Intraoperative return of urine output occurred immediately after completion of the bypass. Hemodialysis, which was required preoperatively, was stopped after renal salvage, the patient has maintained a normal glomerular filtration rate and patency of her bypass by duplex follow-up.

    The ideal time for distinguishing a renal scar from acute inflammatory lesions by renal DMSA scintigraphy remains controversial. To determine the time needed for resolution of lesions after acute pyelonephritis. A total of 105 children with acute pyelonephritis underwent renal sonography, voiding cystourethrography and baseline DMSA scintigraphy. Two subsequent scans were performed during the 6th and 12th months in patients with abnormal findings on the previous scan. The baseline DMSA scintigraphy revealed cortical lesions in 37 patients. At 6 months, 13 patients (38.2%) were found to have cortical lesions. At 12 months, 6 patients (17.6%) were found to have persistent renal cortical lesions. The resolution rates for lesions detected on the first scan were 61.8% and 82.4% on the 6- and 12-month scans, respectively. Vesicoureteric reflux, and bilaterality or multifocality were not relevant for resolution of lesions. Female gender seemed to be associated with a higher persistence rate. The renal cortical defects present at 6 months have a high rate of resolution later during follow-up. DMSA scintigraphy performed 12 months after the infection provides more reliable data regarding persistence of renal cortical lesions. (orig.)

    Objectives: To study the prevalence and characteristics of renal and perirenal space involvement and its relation to the severity of acute pancreatitis (AP) using MRI. Methods: 115 patients with AP who underwent MRI with the clinical kidney function test were retrospectively analyzed in this study. MRI sequences included conventional and diffusion weighted imaging (DWI) sequences. The renal and perirenal space involvement in AP was noted on MRI. The renal apparent diffusion coefficient (ADC) on DWI was measured for each kidney. The severity of AP on MRI was graded using MR severity index (MRSI). The relationships among the renal and perirenal space involvement on MRI, the renal ADC, MRSI and the results of the kidney function test were analyzed. Results: In the 115 patients with AP, the renal and perirenal space abnormalities detected included renal parenchymal abnormalities (0.8%), abnormalities of the renal collecting system (2.6%), renal vascular abnormalities (1.7%), thickened renal fascia (99%), perirenal stranding (62%) and perirenal fluid collection (40%). The prevalence of perirenal space abnormalities was correlated with the severity of AP based on MRSI (P < 0.05). The renal ADC values were lower in patients with abnormal kidney function than in those without kidney injury (P < 0.05). The prevalence of kidney function abnormalities was 9.4%, 32% and 100% in mild, moderate, and severe AP cases, respectively (P = 0.00). Conclusion: Perirenal space involvement is much more than renal parenchymal involvement in AP. The prevalence of perirenal space involvement in AP on MRI has a positive correlation with the severity of AP according to MRSI.

  13. Role of renal oxygenation and mitochondrial function in the pathophysiology of acute kidney injury.

    There are unique features of renal oxygenation that render the kidney susceptible to oxygen demand-supply mismatch and hypoxia. Renal oxygen consumption by oxidative metabolism is closely coupled to and driven by tubular transport, which is linked to the filtered solute load and glomerular filtration rate (GFR). In turn, filtered solute load and GFR are dependent on the renal blood flow. Hence, changes in renal blood flow increase oxygen delivery but also increase oxygen demand (consumption) simultaneously by increasing the tubular workload of solute transport. The renal blood flow to different regions of kidney is also inhomogeneous, increasing the oxygen demand-supply mismatch in particular areas such as the outer medulla which become more susceptible to injury. Thus, tubular transport and oxidative metabolism by miochondria are closely coupled in the kidney and are the principal determinants of intrarenal oxygenation. Here we review the published literature characterizing renal oxygenation and mitochondrial function in ischemic and sepsis-associated acute kidney injury (AKI). However, the coupling of transport and metabolism in AKI has not been examined. This is a potentially fruitful area of research that should become increasingly active given the emerging data linking renal oxygenation and hypoxia to acute and chronic dysfunction in the kidney. 2014 S.

    Vitamin D receptor (VDR) is highly expressed in human and mouse kidneys. Nevertheless, its functions remain obscure. This study investigated the effects of vitamin D3 (VitD3) pretreatment on renal inflammation during lipopolysaccharide (LPS)-induced acute kidney injury. Mice were intraperitoneally injected with LPS. In VitD3 + LPS group, mice were pretreated with VitD3 (25 μg/kg) at 48, 24 and 1 h before LPS injection. As expected, an obvious reduction of renal function and pathological damage was observed in LPS-treated mice. VitD3 pretreatment significantly alleviated LPS-induced reduction of renal function and pathological damage. Moreover, VitD3 pretreatment attenuated LPS-induced renal inflammatory cytokines, chemokines and adhesion molecules. In addition, pretreatment with 1,25(OH)2D3, the active form of VitD3, alleviated LPS-induced up-regulation of inflammatory cytokines and chemokines in human HK-2 cells, a renal tubular epithelial cell line, in a VDR-dependent manner. Further analysis showed that VitD3, which activated renal VDR, specifically repressed LPS-induced nuclear translocation of nuclear factor kappa B (NF-κB) p65 subunit in the renal tubules. LPS, which activated renal NF-κB, reciprocally suppressed renal VDR and its target gene. Moreover, VitD3 reinforced the physical interaction between renal VDR and NF-κB p65 subunit. These results provide a mechanistic explanation for VitD3-mediated anti-inflammatory activity during LPS-induced acute kidney injury.

    Full Text Available SUMMARYAcute renal failure is a syndrome that usually runs with an increase in creatinine and urea plasma levels. However, there are clinical situations in which this syndrome may run with an increase in plasma creatinine keeping normal the urea one.In this report we present a case of acute renal failure with normal plasma urea level secondary to an acute pyelonephritis in a single kidney patient. The patient had an increased fractional excretion of urea which could explain the normal plasma urea levels found despite of his reduced glomerular filtration. This increased urea excretion state was interpreted as a consequence of the nephrogenic diabetes insipidus and alteration of the intra-renal urea reciclying process that the acute pyelonephritis induced. In conclusion: Acute pyelonephritis in a single kidney patient can appear as a pattern of acute renal failure with normal plasma urea levels. RESUMEN:La insuficiencia renal aguda es un sindrome que característicamente cursa con niveles plasmáticos elevados de urea y creatinina. Sin embargo, hay situaciones clínicas en las cuales este sindrome puede cursar con un incremento de la creatininemia sin presentar elevación de la uremia.En este reporte presentamos un caso clínico de una insuficiencia renal aguda con uremia normal secundaria a una pielonefritis aguda en un paciente con riñón único. El paciente presentaba una elevada excreción fraccional de urea lo cual podía explicar su uremia normal pese a estar cursando una caída del filtrado gomerular. Dicha excreción de urea elevada fue interpretada como secundaria a una diabetes insipida nefrogénica y una alteración en el recirculado intra-renal de la urea ambos producto de la pielonefritis aguda. Concluimos que la pielonefritis aguda en un paciente mono-reno puede presentarse con un patrón de insuficiencia renal aguda con uremia normal.

    Full Text Available Hydrogen (H2, a new antioxidant, was reported to reduce •OH and ONOO− selectively and inhibit certain proinflammatory mediators to product, without disturbing metabolic redox reactions or ROS involved in cell signaling. We herein aim to explore its protective effects on acute renal injury in sodium taurocholate-induced acute pancreatitis and its possible mechanisms. Rats were injected with hydrogen-rich saline (HRS group or normal saline (SO and SAP group through tail intravenously (6 mL/kg and compensated subcutaneously (20 mL/kg after successful modeling. Results showed that hydrogen-rich saline attenuated the following: (1 serum Cr and BUN, (2 pancreatic and renal pathological injuries, (3 renal MDA, (4 renal MPO, (5 serum IL-1β, IL-6, and renal TNF-α, HMGB1, and (6 tyrosine nitration, IκB degradation, and NF-κB activation in renal tissues. In addition, it increased the level of IL-10 and SOD activity in renal tissues. These results proved that hydrogen-rich saline attenuates acute renal injury in sodium taurocholate-induced acute pancreatitis, presumably because of its detoxification activity against excessive ROS, and inhibits the activation of NF-κB by affecting IκB nitration and degradation. Our findings highlight the potential value of hydrogen-rich saline as a new therapeutic method on acute renal injury in severe acute pancreatitis clinically.

    INTRODUCTION: In ICU the need for acute renal replacement therapy (RRT) associates with high mortality and risk of end-stage renal disease (ESRD), but there are limited long-term data. We investigated these outcomes and their risk factors. METHODS: Retrospective analysis of all adult patients...... admitted to a general, university hospital ICU 2005-2012, excluding chronic dialysis patients. ESRD was defined as need of RRT > 90 days or kidney transplant. RESULTS: Of 5766 patients included, 1004 (16%) received acute RRT; their 30-day mortality was 42% vs. 16% for those not requiring acute RRT...... (adjusted hazard ratio (HR) 1.13 (0.96-1.32)). The 90-day mortality was 55% for patients receiving acute RRT vs. 22% for those who did not (adjusted HR 1.32 (1.15-1.51)) and 1-year mortality was 63% vs. 30%, respectively, (adjusted HR 1.31 (1.16-1.48)).

    Objective: The diagnosis of acute pyelonephritis in children remains a clinical challenge. It may cause permanent renal scar formation and results in the chronic renal failure if prompt diagnosis and treatment are delayed. The purpose of this study is to compare magnetic resonance imaging (MRI) and renal cortical scintigraphy (RCS) findings in childhood acute pyelonephritis and to determine pyelonephritic foci in the acute phase. Materials and method: Twenty children (15 females and five males) with symptoms dysuria, enuresis, costovertebral pain, fever of 37.5 degree sign C or more and/or positive urine culture were imaged by unenhanced turbo spin echo T2, spin echo T1-weighted, pre- and post-gadolinium inversion recovery MRI and RCS. Both imaging techniques were read independently by two radiologists and nuclear medicine specialists. Sensitivity and specificity of MRI in detecting acute pyelonephritic foci and scar lesions were calculated. Furthermore, in order to calculate the reliability of MRI over RCS in differentiating scar tissue and acute pyelonephritic foci, follow-up MRI studies were done in six patients after treatment of acute pyelonephritis. Results: Sensitivity and specificity of MRI in the detection of pyelonephritic lesions were found to be 90.9 and 88.8%, respectively. There is no statistically significant difference in lesion detection between the two diagnostic modalities (P>0.05). Conclusion: Post-gadolinium MR images show significant correlation with RCS in the determination of renal pathology. Moreover, the ability of discriminating acute pyelonephritic foci and renal scar in early stages of disease is the superiority of MRI.

    Full Text Available Objective To evaluate the value of color Doppler flow imaging (CDFI and pulsed-wave Doppler (PWD in monitoring renal hemodynamics in rabbits with acute hemorrhagic shock. Methods The experimental model of acute hemorrhagic shock was reproduced in 16 normal New Zealand white rabbits by controlled exsanguination which was divided into 4 different grades: normal (100% MAP, mild (70% MAP, moderate (50% MAP, and severe (40% MAP. The right kidney of the experimental animal was examined by gray-scale ultrasound (2DUS, CDFI and PWD. The structure of the right kidney was observed with 2DUS. CDFI was used to monitor the change in right renal hemodynamics along with the progression of shock. The hemodynamic parameters of main renal artery (MRA, segmental renal artery (SRA and interlobar renal artery (IRA were measured by PWD, including the peak systolic velocity (Vmax, minimum diastolic velocity (Vmin and resistive index (RI. Results The animal model of hemorrhagic shock was successfully reproduced in 16 healthy New Zealand rabbits, of which 14 rabbits survived at the end of the experiment, and 2 died of severe shock. The mean arterial pressure (MAP declined, while the respiratory rate and heart rate increased as the circulation changed from normal to severe shock (P<0.05. Observation of the right renal structure by 2DUS revealed no obvious changes after bleeding in different degrees. CDFI showed a gradually reduced distribution of blood flow in renal hemodynamics along with the progression of hemorrhagic shock. Vmax and Vmin declined gradually, while RI intensity increased as the hemorrhagic shock progressed from minor to severe. There was statistically significant difference in RI intensity between different grades of shock (P<005. Conclusion CDFI and PWD can quantitatively assess the renal hemodynamics during acute hemorrhagic shock, so it can be used as a noninvasive monitoring tool in the diagnosis and treatment of hemorrhagic shock.

    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.

    2012-05-01

    This study was aimed at evaluating the clinicopathologic features of plasma cell-rich acute rejection (PCAR) of renal allograft and comparing them with acute cellular rejection (ACR), non-plasma cell-rich type. During a 2-year period, eight renal allograft biopsies were diagnosed as PCAR (plasma cells >10% of interstitial infiltrate). For comparison, 14 biopsies with ACR were included in the study. Detailed pretransplant data, serum creatinine at presentation, and other clinical features of all these cases were noted. Renal biopsy slides were reviewed and relevant immunohistochemistry performed for characterization of plasma cell infiltrate. The age range and duration of transplantation to diagnosis of acute rejection were comparable in both the groups. Histologically, the proportion of interstitial plasma cells, mean interstitial inflammation, and tubulitis score were higher in the PCAR group compared with cases with ACR. A significant difference was found in the outcome at last follow-up, being worse in patients with PCAR. This study shows that PCAR portends a poor outcome compared with ACR, with comparable Banff grade of rejection. Due to its rarity and recent description, nephrologists and renal pathologists need to be aware of this entity.

    2007-04-01

    Percutaneous nephrolithotomy (PCNL) involves gaining access into the urinary collecting system to remove kidney stones. Animal studies demonstrated that a reduction in renal filtration and perfusion in both kidneys, and a decline in tubular organic anion transport in the treated kidney characterizes the acute (hours) functional response to unilateral percutaneous access. The acute morphologic and histological changes in the treated kidney were consistent with blunt trauma and ischemia. Only tubular organic anion transport remained depressed during the late (3-day) response to the access procedure. Human studies revealed an acute decline in glomerular function and bilateral renal vasoconstriction following unilateral PCNL. Therefore, percutaneous access is not a benign procedure, but is associated with acute functional and structural derangements.

    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.

    Administration of human recombinant erythropoietin (EPO) at time of acute ischemic renal injury (IRI) inhibits apoptosis, enhances tubular epithelial regeneration, and promotes renal functional recovery. The present study aimed to determine whether darbepoetin-alfa (DPO) exhibits comparable renoprotection to that afforded by EPO, whether pro or antiapoptotic Bcl-2 proteins are involved, and whether delayed administration of EPO or DPO 6 h following IRI ameliorates renal dysfunction. The model of IRI involved bilateral renal artery occlusion for 45 min in rats (N = 4 per group), followed by reperfusion for 1-7 days. Controls were sham-operated. Rats were treated at time of ischemia or sham operation (T0), or post-treated (6 h after the onset of reperfusion, T6) with EPO (5000 IU/kg), DPO (25 mug/kg), or appropriate vehicle by intraperitoneal injection. Renal function, structure, and immunohistochemistry for Bcl-2, Bcl-XL, and Bax were analyzed. DPO or EPO at T0 significantly abrogated renal dysfunction in IRI animals (serum creatinine for IRI 0.17 +/- 0.05 mmol/l vs DPO-IRI 0.08 +/- 0.03 mmol/l vs EPO-IRI 0.04 +/- 0.01 mmol/l, P = 0.01). Delayed administration of DPO or EPO (T6) also significantly abrogated subsequent renal dysfunction (serum creatinine for IRI 0.17 +/- 0.05 mmol/l vs DPO-IRI 0.06 +/- 0.01 mmol/l vs EPO-IRI 0.03 +/- 0.03 mmol/l, P = 0.01). There was also significantly decreased tissue injury (apoptosis, P EPO at T0 or T6. These results reaffirm the potential clinical application of DPO and EPO as novel renoprotective agents for patients at risk of ischemic acute renal failure or after having sustained an ischemic renal insult.

    Full Text Available Abstract Background Diabetes mellitus and renal dysfunction are prognostic factors after acute myocardial infarction (AMI. However, few studies have assessed the effects of renal insufficiency in association with diabetes in the context of AMI. Here, we investigated the clinical outcomes according to the concomitance of renal dysfunction and diabetes mellitus in patients with AMI. Methods From November 2005 to August 2008, 9905 patients (63 ± 13 years; 70% men with AMI were enrolled in a nationwide prospective Korea Acute Myocardial Infarction Registry (KAMIR and were categorized into 4 groups: Group I (n = 5700 had neither diabetes nor renal insufficiency (glomerular filtration rate [GFR] ≥ 60 ml/min/1.73 m2, Group II (n = 1730 had diabetes but no renal insufficiency, Group III (n = 1431 had no diabetes but renal insufficiency, and Group IV (n = 1044 had both diabetes and renal insufficiency. The primary endpoints were major adverse cardiac events (MACE, including a composite of all cause-of-death, myocardial infarction, target lesion revascularization, and coronary artery bypass graft after 1-year clinical follow-up. Results Primary endpoints occurred in 1804 (18.2% patients. There were significant differences in composite MACE among the 4 groups (Group I, 12.5%; Group II, 15.7%; Group III, 30.5%; Group IV, 36.5%; p p = 0.001; and HR, 2.42; 95% CI, 1.62-3.62; p Conclusions Renal insufficiency, especially in association with diabetes, is associated with the occurrence of composite MACE and indicates poor prognosis in patients with AMI. Categorization of patients with diabetes and/or renal insufficiency provides valuable information for early-risk stratification of AMI patients.

    Full Text Available Abstract Introduction – Acute renal failure (ARF has a poor prognosis in patients with cancer requiring intensive care unit (ICU admission. Our aim is finding prognostic factors for hospital mortality in patients with cancer with ARF requiring renal replacement therapy (RRT. Methods – In this retrospective study, all patients with cancer with ARF treated with continuous venovenous filtration (CVVHDF in the ICU of the Institut Jules Bordet, between January 1st 2003 and December 31st 2012, were included in the study.Results – 103 patients are assessed: men/women 69/34, median age 62 years, solid/haematologic tumours 68/35, median SAPS II 56. Mortality rate was 63%. Seven patients required chronic renal dialysis. After multivariate analysis, two variables were statistically associated with hospital mortality : more than one organ failure (including kidney (OR 5.918 ; 95% CI 2.184 – 16.038 ; p<0,001 and low albumin level (OR 3.341; 95% CI 1.229 – 9.077; p=0,02. Only minor complications related to CVVHDF have been documented.Conclusions – Despite the poor prognosis associated with ARF, CVVHDF is an effective and tolerable renal replacement technique in patients with cancer admitted to the ICU. Multiple organ failure and hypoalbuminemia, two independent prognostic factors for hospital mortality have to be considered when deciding for introducing RRT.

    Full Text Available Acute generalized exanthematous pustulosis (AGEP is a severe adverse cutaneous reaction characterized by an acute episode of sterile pustules over erythematous-edematous skin. The main triggering drugs are antibiotics, mainly beta-lactam and macrolides. Non-steroid anti-inflammatory drugs may rarely be responsible. We describe a case of a woman with AGEP, who presented with generalized pustulosis lesions after the use of piroxicam for renal colic. The diagnosis was confirmed by the clinical and histological correlations and the dermatosis resolved after withdrawal of the drug.

    2012-06-01

    Full Text Available Abstract Background Neutrophil gelatinase associated lipocalin (NGAL is a highly predictive biomarker of acute kidney injury. To understand the role of NGAL in renal injury during sepsis, we investigated the temporal changes and biological sources of NGAL in a rat model of acute kidney injury, and explored the relationship between renal inflammation, humoral NGAL and NGAL expression during endotoxemia. Methods To induce acute renal injury, rats were treated with lipopolysaccharide (LPS, 3.5 mg/kg, ip, and the location of NGAL mRNA was evaluated by in situ hybridization. Quantitative RT-PCR was also used to determine the dynamic changes in NGAL, tumor necrosis factor α (TNFα and interleukin (IL-6 mRNA expression 1, 3, 6, 12, and 24 hours following LPS treatment. The correlation among NGAL, TNFα and IL-6 was analyzed. Urinary and plasma NGAL (u/pNGAL levels were measured, and the relationship between humoral NGAL and NGAL expression in the kidney was investigated. Results Renal function was affected 3–12 hours after LPS. NGAL mRNA was significantly upregulated in tubular epithelia at the same time (P P P P Conclusions NGAL upregulation is sensitive to LPS-induced renal TNFα increase and injury, which are observed in the tubular epithelia. Urinary NGAL levels accurately reflect changes in NGAL in the kidney.

    We investigated three possible causes of the increased ratio of amylase/creatinine clearance observed in acute pancreatitis. The presence of rapidly cleared isoamylase was excluded by studies of serum and urine, which demonstrated no anomalous isoamylases. In pancreatitis, the ratios (+/-1 S.E.M.) of both pancreatic isoamylase (9.2+/-0.6 per cent) and salivary isoamylase (8.6+/-1.6 per cent) were significantly (P less than 0.01) elevated over respective control values (2.4+/-0.2 and 1.8+/-0.2 per cent). Increased glomerular permeability to amylase was excluded by the demonstration of normal renal clearance of dextrans. We tested tubular reabsorption of protein by measuring the renal clearance of beta2-microglobulin, which is relatively freely filtered at the glomerulus and then avidly reabsorbed by the normal tubule. During acute pancreatitis the ratio of the renal clearance of beta2-microglobulin to that of creatinine was 1.22+/-0.52 per cent, an 80-fold increase over normal (0.015+/-0.002 per cent), with a rapid return toward normal during convalescence. Presumably, this reversible renal tubular defect also reduces amylase reabsorption and accounts for the elevated renal clearance of amylase/creatinine observed in acute pancreatitis.

    Full Text Available Restrictive renal diet (low protein, low potassium, low phosphate and low salt is frequently ordered for patients with acute and chronic renal failure. This is however not necessary for all renal patients, who are at risk of compromised nutrition. Nutritional status of 60 patients (35 males, 25 females; mean age: 67±17; mean BMI: 23.4±4.6 kg/m2 with renal failure was assessed using the Subjective Global Assessment (SGA. 53%, 45% and 2% of patients were classified as well nourished, mild-moderately malnourished and severely malnourished respectively. SGA ratings had the strongest correlation with serum albumin (r=−0.226, p=0.082 compared with age (r=0.153, p=0.243, BMI (r=−0.204, p=0.139 and eGFR (r=−0.055, p=0.679. Patients with acute and chronic renal failure were equally likely to have compromised nutritional status. Similarly there was no difference in nutritional status between patients with and without dialysis (p=0.498. In conclusion, the prevalence of compromised nutritional status in hospitalized renal patients was high at 47%. Dietetic intervention is necessary to prevent further decline in nutritional status of this group of patients. Dietary restrictions should be personalized and based on biochemical profile.

    We report our experience using catheter-directed thrombectomy/thrombolysis (CDT) to treat a patient with acute renal vein thrombosis (RVT) associated with systemic lupus erythematosus (SLE). A 34-year-old woman presented with persistent left flank pain, and a renal ultrasonography examination revealed an enlarged left kidney. Contrast-enhanced computed tomography confirmed the presence of acute left RVT. Because medical treatment failed to relieve her pain and the renal function was deteriorating, we attempted to salvage the occluded left renal vein using an endovascular approach. The pain was completely relieved after a CDT and an overnight urokinase infusion. A follow-up computed tomography examination revealed the complete resolution of the thrombus. The creatinine level returned to normal (1.7-0.4 mg/dL), along with contrast enhancement in the left kidney, and this suggested the preservation of renal function. To our knowledge, this is the first report utilizing CDT to treat SLE-associated RVT. When the renal function is deteriorating, CDT is worth considering for RVT if conventional medical treatment has failed. © 2016 Wiley Periodicals, Inc.

    Background In 2008, infants in some areas of China suffered from stones of the urinary system which were caused by melamine-contaminated milk formula. Most of the infants were asymptomatic, and a few suffered from acute renal failure induced by urinary obstruction by stones. This study aimed to assess the significance of blood purification therapy in treatment of infants with acute obstructive oligo-anuric renal failure. Corrective perception, timely diagnosis, and active treatment of this complex disease are critical factors that guarantee a quick recovery of renal function of infants and help them to prevent multiple organ system failure.Methods Thirteen infants with acute renal failure induced by urinary multiple obstruction caused by melamine-containing stones who had been admitted to Beijing Children's Hospital Affiliated to Capital Medical University in 2008 were investigated for the epidemiological characteristics, image features and indications of dialysis. All these infants were treated with dialysis. The efficacy of dialysis was compared with that of two control groups treated with cystoscopic retrograde catheterization into the ureter and medical treatment for the recovery of renal function.Results The 13 infants with life-threatening complications treated with dialysis showed a blood urea nitrogen (BUN) level of (30.9±7.9) mmol/L and a creatinine (Cr) level of (572+173) pmol/L. Of these infants, 8 were treated with peritoneal dialysis (PD), and 5 with hemodialysis (HD). Ten infants recovered to urinate 24-72 hours after dialysis and 3 infants with persistent ureteral obstruction were further treated with cystoscopic retrograde catheterization into the ureter for drainage, and urination resumed soon after the operation. The average time of PD and HD were (2.1±0.8) days and (1.2±0.4) days, respectively. The total average time of PD and HD dialysis was (1.77±0.83) days. The recovery time of renal function of infants after dialysis was (3.08±1.20) days

    Full Text Available Context: There is a need for identifying risk factors aggravating development of acute renal failure after attaining trauma and defining new parameters for better assessment and management. Aim of the study was to determine the incidence of acute renal failure among trauma patients, and its correlation with various laboratory and clinical parameters recorded at the time of admission and in-hospital mortality. Subjects and Methods: The retrospective cohort study included admitted 208 trauma patients over a period of one year. 135 trauma patients at the serum creatinine level >2.0 mg/dL were enrolled in under the group of acute renal failure. 73 patients who had normal creatinine level made the control group. They were further assessed with clinical details and laboratory investigations. Results: Incidence of acute renal failure was 3.1%. There were 118 (87.4% males and average length of stay was 9 (1, 83 days. Severity of injury (ISS, GCS was relatively more among the renal failure group. Renal failure was transient in 35 (25.9% patients. They had higher incidence of bone fracture (54.0% (P = 0.04. Statistically significant association was observed between patients with head trauma and mortality 72 (59.0% (P = 0.001. Prevalence of septic 24 (59.7% and hemorrhagic 9 (7.4% shock affected the renal failure group. Conclusion: Trauma patients at the urea level >50 mg/dL, ISS >24 on the first day of admission had 23 times and 7 times the risk of developing renal failure. Similarly, patients with hepatic dysfunction and pulmonary dysfunction were 12 times and 6 times. Patients who developed cardiovascular dysfunction, hematological dysfunction and post-trauma renal failure during the hospital stay had risk for mortality 29, 7 and 8 times, respectively. The final prognostic score obtained was: 14FNx01hepatic dysfunction + 11FNx01cISS + 18FNx01cUrea + 12FNx01cGlucose + 10FNx01pulmonary dysfunction. Optimal score cut-off for prediction of renal failure was

    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.

Tests revealed a hemolytic anemia with thrombocytopenia. An initial diagnosis of thrombotic thrombocytopenic microangiopathy was made and plasma exchange was instigated. However, renal biopsy did not show thrombotic microangiopathy but instead revealed acute kidney injury with mild tubulointerstitial nephritis and numerous oxalate crystals, predominantly in the distal tubules. The patient had been taking large doses (>1100 mg daily of vitamin C for many months. She also gave a history of sclerotherapy using injections of an ethylene glycol derivative for superficial leg veins. The patient completed five sessions of plasma exchange and was able to discontinue dialysis. She eventually achieved full renal recovery. She has now discontinued sclerotherapy and vitamin supplementation.

    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.

    Kidney allografts induce strong T-cell and antibody responses which mediate acute rejection. Spleen tyrosine kinase (Syk) is expressed by most leucocytes, except mature T cells, and is involved in intracellular signalling following activation of the Fcγ-receptor, B-cell receptor and some integrins. A role for Syk signalling has been established in antibody-dependent native kidney disease, but little is known of Syk in acute renal allograft rejection. Sprague-Dawley rats underwent bilateral nephrectomy and received an orthotopic Wistar renal allograft. Recipient rats were treated with a Syk inhibitor (CC0482417, 30 mg/kg/bid), or vehicle, from 1 h before surgery until being killed 5 days later. Vehicle-treated recipients developed severe allograft failure with marked histologic damage in association with dense leucocyte infiltration (T cells, macrophages, neutrophils and NK cells) and deposition of IgM, IgG and C3. Immunostaining identified Syk expression by many infiltrating leucocytes. CC0482417 treatment significantly improved allograft function and reduced histologic damage, although allograft injury was still clearly evident. CC0482417 failed to prevent T-cell infiltration and activation within the allograft. However, CC0482417 significantly attenuated acute tubular necrosis, infiltration of macrophages and neutrophils and thrombosis of peritubular capillaries. In conclusion, this study identifies a role for Syk in acute renal allograft rejection. Syk inhibition may be a useful addition to T-cell-based immunotherapy in renal transplantation.

    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.

    Imbalance between renal oxygen delivery and demand in the first hours after reperfusion is suggested to be decisive in the pathophysiological chain of events leading to ischemia-induced acute kidney injury. Here we describe blood oxygenation level-dependent (BOLD) magnetic resonance imaging (MRI) for continuous monitoring of the deoxyhemoglobin-sensitive MR parameter T 2* in the renal cortex, outer medulla, and inner medulla of rats throughout renal ischemia/reperfusion (I/R). Changes during I/R are benchmarked against the effects of variations in the fraction of inspired oxygen (hypoxia, hyperoxia). This method may be useful for investigating renal blood oxygenation of rats in vivo under various experimental (patho)physiological conditions.

    Full Text Available We report a 52-year-old male with no family history of colonic cancer, who was found to have advanced colonic cancer with metastases two months post renal transplantation. With this case, we highlight the possibility of acute fulminant cancer metastases within short period after renal transplantation and the importance of periodic colorectal cancer screening pre-transplant. To our knowledge, this case is not yet reported in the literature, especially with such presentation of acute fulminant colonic cancer metastases post renal transplantation.

The HANDOUT study had examinded mortality and renal recovery of patients with AKI receiving either standard extendend or intensified dialysis after multi organ failure. Results: One hundred fifty-six former HANDOUT participants were analyzed. In-hospital mortality was 56.4%. Five-year survival after AKI/RRT was 40.1% (86.5% if discharged from hospital. Main causes of death were cardiovascular complications and sepsis. A total of 19 survivors presented to the outpatient department of our clinic and had good renal recovery (mean estimated glomerular filtration rate 72.5±30 mL/min/1.73 m2; mean proteinuria 89±84 mg/d.

    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.

    Gallbladder disease due to stones is well recognised as falling into two categories, presenting with either chronic symptoms or developing acute cholecystitis or other complications. We describe an intermediate group of 14 patients (11 women, three men, median age 31 years) presenting with 4-14 days of at least daily attacks of resolving biliary colic, who underwent early laparoscopic cholecystectomy within 24 hours of presentation. None had any evidence of acute inflammation, either at laparoscopy or on histology. Their surgery was straightforward with operating times ranging from 35-80 minutes and no complications. Patients with 'crescendo biliary colic' are often young women who can rarely afford invalidity. Rather than the current practice of analgesia for each attack and elective surgery weeks later, they are optimally managed by urgent laparoscopic cholecystectomy, preventing the development of complications and minimising the need for further medical involvement.

    Sheehan's syndrome occurs as a result of ischemic pituitary necrosis secondary to severe postpartum bleeding. It is one of the most common causes of hypopituitarism, characterized by variable clinical presentation. Acute kidney injury occurs rarely in Sheehan's syndrome and most of the cases have been found to be precipitated by rhabdomyolysis. We here present a case of Sheehan's syndrome with acute kidney injury where theprecipitating cause was chronic hypocortisolemia. We believe this is the first reported case of Sheehan's syndrome in which acute kidney injury was precipitated by adrenal insufficiency.

    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.

    Background Invasive kidney biopsy is a priority diagnostic method for the acute rejection after renal transplantation for the past decades. However, no effective and noninvasive assay for predicting the severity of acute rejection is in wide use at present. This study was designed to investigate the predictive value of programmed death 1 (PD-1) mRNA for acute rejection after renal transplantation with real-time reverse transcriptase polymerase chain reaction (RT-PCR). A noninvasive diagnostic method has been expected to replace the tranditional kidney biopsy for the diagnosis of acute rejection and prediction of the outcome after kidney transplantation.Methods The whole blood samples from 19 subjects with acute rejection, 20 subjects with delayed graft function (DGF)and 21 subjects with stable recipients after kidney transplantation in a single kidney transplantation center between 2006 and 2009 were collected. The messenger RNA (mRNA) of PD-1 was analyzed with real-time RT-PCR. The associations of PD-1 mRNA levels with acute rejection and disease severity were investigated.Results The log-transformed ratio of PD-1 mRNA to GAPDH mRNA was higher in peripheral blood mononuclear cell (PBMC) from the group with acute rejection (4.52±1.1) than that from the group with DGF (1.12±0.6) or the group with normal biopsy results (0.7±0.4) (P <0.01, by the Kruskal-Wallis test). PD-1 mRNA levels were correlated with serum creatinine levels measured at the time of biopsy in the acute rejection group (Spearman's correlation coefficient, r=0.81,P=0.03), but not in the group with DGF or the group with normal biopsy results. PD-1 mRNA levels identified subjects at risk for graft failure within six months after the incident episode of acute rejection.Conclusions Our data suggest that PD-1 status may be a new predictor of acute rejection and the levels of PD-1mRNA in whole blood cells may positively correlate with the severity of acute rejection after renal transplantation

    Full Text Available Vasculotoxic snake bites are well known to cause local complications like necrosis and cellulitis and systemic complications such as coagulopathy, acute renal failure (ARF, and hemolysis. We report a case of young female patient who was bitten by a viper. She developed cellulitis, sepsis, ARF, and Disseminated Intravascular Coagulation. She was treated for the above complications and all her renal and hematological parameters returned to normal on seventh day. After this, on the same day, patient developed Acute Respiratory Distress Syndrome probably due to the direct toxic effect of venom on pulmonary vascular endothelium which has been reported as a late complication of snake venom. With close monitoring and proper management of complications, the patient recovered and walked out of the hospital on the twenty first day without any complications.

    To identify acute renal allograft rejection biomarkers in human serum, two-dimensional differential in-gel electrophoresis (2-D DIGE) and reversed phase high-performance liquid chromatog-raphy (RP-HPLC) followed by electrospray ionization mass spectrometry (ESI-MS) were used. Serum samples from renal allograft patients and normal volunteers were divided into three groups: acute rejec-tion (AR), stable renal function (SRF) and normal volunteer (N). Serum samples were firstly processed using Multiple Affinity Removal Column to selectively remove the highest abundance proteins. Differ-entially expressed proteins were analyzed using 2-D DIGE. These differential protein spots were ex-cised, digested by trypsin, and identified by RP-HPLC-ESI/MS. Twenty-two differentially expressed proteins were identified in serum from AR group. These proteins included complement C9 precursor,apolipoprotein A-Ⅳ precursor, vitamin D-binding protein precursor, beta-2-glycoprotein 1 precursor,etc. Vitamin D-binding protein, one of these proteins, was confirmed by ELISA in the independent set of serum samples. In conclusion, the differentially expressed proteins as serum biomarker candidates may provide the basis of acute rejection noninvasive diagnosis. Confirmed vitamin D-binding protein may be one of serum biomarkers of acute rejection. Furthermore, it may provide great insights into un-derstanding the mechanisms and potential treatment strategy of acute rejection.

    Acute renal failure (ARF) is one of the complications of urolithiasis, but the role of medical treatment to relieve urinary obstruction in children with ARF is uncertain. We report on infants with acute obstructive uric acid lithiasis. We describe presentation features as well as diagnosis methods and medical treatment in five infants who were admitted to our institution with ARF due to uric acid lithiasis. The medical treatments for all patients were fluid liberalization, urine alkalinization, and oral allopurinol. Two children underwent urinary diversion. Within 8 h, urine output improved in all patients, and the stones passed spontaneously. All obstructed kidneys were relieved with medical treatment, and no renal sequel remained. So this series has showed a role of medical therapy in acute obstructive uric acid lithiasis.

    The treatment of the acute renal allograft rejection with the monoclonal antibody orthoclone OKT3 produces both systemic and neurologic alterations. In a series of 21 patients with an acute renal allograft rejection treated with this monoclonal antibody, 20 with a renal allograft transplantation and one with a renal and pancreatic allograft transplantation, 29% referred headache associated with fever and vomiting, and 14.2% presented severe neurological alterations induced by the treatment. We stress the need to know these secondary effects to differentiate them from other central nervous system disorders, particularly those of infectious origin.

    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.

    This descriptive report describes the case of a 50 year-old woman with bipolar disorder, whose maintenance therapy comprised risperidone, sodium valproato and lithium carbonate without any past occurrence of toxicity. Her past medical history was significant for hypertension, cardiopathy and obesity. She presented with a 1-week history of fever, increasing confusion and slurred speech. At presentation, the patient was somnolent. Laboratory investigations revealed a serum creatinine of 3,6 mg/dl, BUN 45 mg/dl serum lithium 3,0 mEq/L with polyuria defined as more than 3 litres a day. EEG and ECG were abnormal. CT brain scanning and lumbar puncture were negative for brain haemorrage or infection. Lithium toxicity causes impairment of renal concentration and encephalopathy due to lithium recirculation, a mechanism responsible for the so-called cerebro-renal syndrome, where dialysis plays an important role in treatment.The patient was treated with continous veno-venous haemodiafiltration (CVVHDF) over 35 hours with gradual improvement of her general condition and efficacy of renal concentration. Our case highlights a few important points. Lithium nefrotoxicity and neurotoxicity can cause a cerebro-renal syndrome even when serum lithium levels are not particularly raised (2,5-3,5 mEq/L). Haemodialysis is the treatment of choice to reduce the molecular mechanisms of lithium-related changes in urinary concentration and reinstate dopaminergic activity in the brain.

    Full Text Available Renal ischemia and reperfusion (I/R is the major cause of acute kidney injury in hospitalized patients. Mechanisms underlying reperfusion-associated injury include recruitment and activation of leukocytes and release of inflammatory mediators. In this study, we investigated the renal effects of acute administration of AVE0991, an agonist of Mas, the angiotensin-(1–7 receptor, the angiotensin-(1–7 receptor, in a murine model of renal I/R. Male C57BL/6 wild-type or Mas−/− mice were subjected to 30 min of bilateral ischemia and 24 h of reperfusion. Administration of AVE0991 promoted renoprotective effects, as seen by improvement of function, decreased tissue injury, prevention of local and remote leucocyte infiltration, and release of the chemokine, CXCL1. I/R injury was similar in WT and Mas−/− mice, suggesting that endogenous activation of this receptor does not control renal damage under baseline conditions. In conclusion, pharmacological interventions using Mas receptor agonists may represent a therapeutic opportunity for the treatment of renal I/R injury.

    Full Text Available The kidney is a very important complicated filtering organ of the body. When the kidney reaches stage 5 chronic kidney disease, end stage renal failure, the preeminent therapy is renal transplantation. Although it is the best form of treatment, lack of kidney donors is still challenging. Therefore, all efforts should be employed to prolong the survival rate of the transplanted kidney. However, graft dysfunction (e.g., acute rejection is one of the serious barriers to long term kidney transplant survival. Currently, graft dysfunction’s gold standard of diagnosis is renal biopsy. Although renal biopsy is helpful, it is not preferred due to its invasive nature, high morbidity rates, and expensiveness. Therefore, noninvasive imaging techniques have become the subject of extensive research and interest, giving a strong promise to replace, or at least to decrease, biopsy usage in diagnosing graft dysfunction. This survey will discuss not only the current diagnosis and treatment of graft dysfunction but also the state-of-the-art imaging techniques in detecting acute renal transplant rejection.

    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

    The effect of three statins (atorvastatin, lovastatin, simvastatin) on the renal function under conditions of experimental acute renal failure in rats was studied. The relatively effective doses were found to possess the most considerable renoprotective properties. All the statins were established to cause the restoration of functional activity of the kidneys under conditions of experimental rhabdomyolytic acute renal failure at various doses, but with the dose of 20 mg/kg they showed the most significant improvement in key indices of kidney function: an increase in diuresis by an average of 32% and glomerular filtration rate by an average of 90%, reduction of proteinuria in more than twice. At the same time, in the animals with acute renal failure the level of creatine phosphokinase was increased by 141%. However, the activity of blood plasma creatine phosphokinase of all animals treated with statins was 14% higher than in the intact control, indicating the minor myotrphic activity of statins in selected mode of administration. Thus, the use of 20 mg/kg dose is the most reasonable from the standpoint of renoprotective efficacy and safety.

    Idiopathic renal hypouricemia (IRHU) is a rare hereditary disease, predisposing the individual to exercise-induced acute renal failure (EIARF) and nephrolithiasis, and it is characterized by increased clearance of renal uric acid. Most of the described patients are Japanese, who have loss-of-function mutations in the SLC22A12 gene coding for the human urate transporter 1 (URAT1) gene. An 18-year-old youth, who was admitted for EIARF due to IRHU, and six consanguineous Israeli-Arab family members were included in the study. The family members were tested for fractional excretion of uric acid and molecular analysis of the URAT1 gene. Four family members, including the proband, had very low levels of blood uric acid and high rate of fractional excretion (FE urate> 100%) of uric acid. Genetic analysis of the affected family members did not reveal a mutation in the coding regions and intron-exon boundaries of SCL22A12. Haplotype analysis excluded SCL22A12 involvement in the pathogenesis, suggesting a different gene as a cause of the disease. We herein describe the first Israeli-Arab family with IRHU. A non-URAT1 genetic defect that causes decreased reabsorption or, more probably, increased secretion of uric acid, induces IRHU. Further studies are required in order to elucidate the genetic defect.

    Full Text Available A 68-year-old Caucasian female with a past medical history of a deceased donor kidney transplant four months prior was admitted with a two-day history of anuria and acute kidney injury. A renal ultrasound demonstrated thrombus in the transplanted kidney's renal vein that extended into the left iliac vein as well as into the left femoral venous system. Catheter-guided tissue thrombolytics were infused directly into the clot. Within twelve hours of initiating thrombolytic infusion, there was brisk urine output. Interval venography demonstrated decreasing clot burden. At the time of discharge her creatinine was 0.78 mg/dL, similar to her baseline value prior to presentation. The patient was noted to have May-Thurner syndrome on intravascular ultrasound (IVUS. Angioplasty followed by stent placement was done. Unique to our case report was the timing of the presentation of renal vein thrombosis (four months after transplant and the predisposing anatomy consistent with May-Thurner syndrome, which was diagnosed with IVUS and successfully treated with local thrombolytics.

    Los mecanismos del da no celular en la insuficiencia renal aguda Incluyen alteraciones en la producción de energía, la permeabilidad celular y el transporte de calcio. Dichas alteraciones producen cambios progresivos en la estructura celular que pueden ser reversibles si desaparece la causa que llevó a la falla renal, excepto cuando se alcanza la fase final de la lesión de la membrana y se llega a necrosis celular. Este mismo fenómeno probablemente ocurre tambIén en situaciones clínicas.

    The mechanisms of cellular damage In acute renal failure Include alterations In energy production, cell membrane permeability and calcium transport. These changes lead to progressive damage of the whole cellular structure which In general can be reversible If the precipitating cause disappears, except when the final stages of cell membrane lesion take place and cellular necrosis has occurred. This phenomenon probably applies for the clinical settling as well.

    Kobel, Marie Cæcilie; Nielsen, Tommy Kjærgaard; Graumann, Ole

    Percutaneous drainage proved to be successful in managing a renal subcapsular haematoma that was causing acute renal failure and hypertension in a 74-year-old woman. The patient presented with oliguria, nausea and malaise 2 days after a ureteronephroscopic procedure with biopsies of a suspected...... urothelial neoplasm in the right renal pelvis. The left kidney had recently been removed due to renal cell carcinoma. At admission, the patient's blood pressure and plasma creatinine levels were massively elevated. Ultrasonography revealed a moderate right-sided renal subcapsular haematoma. When the patient...

    Aspergillus species have angioinvasive properties and can involve extrapulmonary organs by hematogenous spread from the lungs. However, renal involvement by Aspergillus is uncommon and is usually associated with the formation of abscesses. We report an unusual case of invasive renal aspergillosis presenting with extensive renal infarction in a 5-year-old girl with acute lymphoblastic leukemia. This case emphasizes the fact that renal aspergillosis initially presents with only renal infarction, and metastatic-embolism by invasive aspergillosis should be considered in differential diagnosis for any focal lesion of kidney in a patient with leukemia.

    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.

    The aim of this study was to investigate the effects of hepatic and renal failure on the pharmacokinetics of flunixin in carbon tetrachloride (CCl(4))- and glycerol-treated rats. After intravenous administration of flunixin (2 mg/kg), the plasma concentration of flunixin was measured by high-performance liquid chromatography. Both acute hepatic and renal failure resulted in significantly increased area under the curve (AUC), prolonged elimination half-life (t(1/2β)), and reduced total body clearance (Cl(tot)) compared with respective controls (Pflunixin.

    Full Text Available Typhoid fever is an important health problem worldwide but its incidence is more in developing countries. Hepatic involvement is common, but both hepatic and renal involvement is rare in typhoid fever. We report a case of typhoid fever presenting with hepatitis and acute renal failure. A 17 year old male presenting with fever and pain abdomen was found to have raised blood urea, creatinine, liver enzymes and bilirubin. Widal and typhidot (IgM,IgG test were positive. His symptoms subsided and deranged parameters resolved with treatment of typhoid fever.

    We describe two cases of fungal granulomatous interstitial nephritis (GIN) presenting as acute kidney injury (AKI). Increased serum creatinine was detected in Patient 1 after chemotherapy for pharyngeal cancer and in Patient 2 after steroid pulse therapy for bronchial asthma. Renal histology of both patients revealed GIN. Polymerase chain reaction (PCR)-based detection of fungal DNA sequences from kidney tissue demonstrated Trichosporon laibachii and Candida albicans, respectively. When AKI occurs in an immunocompromised host, differential diagnosis of fungal interstitial nephritis should be considered. Furthermore, PCR-based detection of fungal DNA sequences from renal specimens can be useful for rapid diagnosis.

    Immunosuppressant agents such as calcineurin inhibitors (CNI) used after solid organ transplantation may cause endothelial dysfunction, and coronary and renal arterial vasospasm. We report a patient presenting acute ST segment elevation myocardial infarction (STEMI) at the second week of renal transplantation. In the case of STEMI in patients with solid organ transplants under immunosuppressive therapy with CNI, coronary vasospasm associated with these drugs should be kept in mind before starting any interventional procedure. High dose nitroglycerine may immediately resolve tacrolimus or cyclosporine A induced coronary vasospasm. Calcium channel blockers should immediately be added to treatment because of the short half-life of nitroglycerine. PMID:26161107

    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.

    2004-09-01

    A prognostic scoring system for hospital mortality in acute renal failure (Stuivenberg Hospital Acute Renal Failure, SHARF score) was developed in a single-centre study. The scoring system consists of two scores, for the time of diagnosis of acute renal failure (ARF) and for 48 h later, each originally based on four parameters (age, serum albumin, prothrombin time and heart failure). The scoring system was now tested and adapted in a prospective study. The study involved eight intensive care units. We studied 293 consecutive patients with ARF in 6 months. Their mortality was 50.5%. The causes of ARF were medical in 184 (63%) patients and surgical in 108 (37%). In the latter group, 74 (69%) patients underwent cardiac and 19 (18%) vascular surgery. As the performance of the original SHARF scores was much lower in the multicentre study than in the original single-centre study, we re-analysed the multicentre data to customize the original model for the population studied. The independent variables were the score developed in the original study plus all additonal parameters that were significant on univariate analysis. The new multivariate analysis revealed an additional subset of three parameters for inclusion in the model (serum bilirubin, sepsis and hypotension). For the modified SHARF II score, r(2) was 0.27 at 0 and 0.33 at 48 h, respectively, the receiver operating characteristic (ROC) values were 0.82 and 0.83, and the Hosmer-Lemeshow goodness-of-fit P values were 0.19 and 0.05. After customizing and by using two scoring moments, this prediction model for hospital mortality in ARF is useful in different settings for comparing groups of patients and centres, quality assessment and clinical trials. We do not recommend its use for individual patient prognosis.

    Purpose There are limited data regarding the clinical use of decitabine for the treatment of acute myeloid leukemia in patients with a serum creatinine of 2 mg/dL or greater. Methods We retrospectively evaluated 111 patients with acute myeloid leukemia who had been treated with decitabine and compared the development of toxicities during cycle 1 in those with normal renal function (creatinine clearance greater than or equal to 60 mL/min) to those with renal dysfunction (creatinine clearance less than 60 mL/min). Results Notable differences in the incidence of grade ≥3 cardiotoxicity (33% of renal dysfunction patients vs. 16% of normal renal function patients, p = 0.042) and respiratory toxicity (40% of renal dysfunction patients vs. 14% of normal renal function patients, p = 0.0037) were observed. The majority of heart failure, myocardial infarction, and atrial fibrillation cases occurred in the renal dysfunction group. The odds of developing grade ≥3 cardiotoxicity did not differ significantly between patients with and without baseline cardiac comorbidities (OR 1.43, p = 0.43). Conclusions This study noted a higher incidence of grade ≥3 cardiac and respiratory toxicities in decitabine-treated acute myeloid leukemia patients with renal dysfunction compared to normal renal function. This may prompt closer monitoring, regardless of baseline cardiac comorbidities. Further evaluation of decitabine in patients with renal dysfunction is needed.

    2000-01-01

    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.

    Acute renal failure (ARF) is one of the most common problems encountered in hospitalized critically ill patients. In recent years great effort has been focused on the introduction of herbal medicine as a novel therapeutic agent for prevention of ARF. Hence, the current study was designed to investigate the effect of Açai berry extract (ABE) on glycerol-induced ARF in rats. Results of the present study showed that rat groups that received oral ABE in a dose of 100 and 200 mg/kg/day for 7 days before or 7 days after induction of ARF by a single intramuscular glycerol injection reported a significant improvement in kidney functions tests [decrease in serum urea, serum creatinine, and blood urea nitrogen (BUN)] when compared to the ARF model groups. Moreover, there was significant amelioration in renal oxidative stress markers [renal catalase (CAT), renal reduced glutathione (GSH)] and renal histopathological changes in the ABE-treated groups when compared to ARF model groups. The most significant improvement was reported in the groups where ABE was administered in a dose 200 mg/kg/day. These results indicate that ABE has a potential role in ameliorating renal damage involved in ARF.

    Full Text Available Background. The aim of this study is to investigate the protective effects of hemin (the heme oxygenase-1 [OH-1] inducer against nephrotoxic effects induced by cisplatin [cis-diamminedichloroplatinum II (CP] in male rats. Methods. The evaluation was performed through monitoring renal redox parameters: lipid peroxidation (LPO, glutathione peroxidase (GPx, superoxide dismutase (SOD, glutathione reductase (GR, and reduced glutathione (GSH. The work also examined renal function tests (urea and creatinine, tissue proinflammatory mediator like nitric oxide (NO, and kidney cytopathology. Results. A single intraperitoneal dose of CP (10 mg/kg b.w. caused significant elevation of blood urea, serum creatinine, and renal LPO and NO, along with significant decline of the activities of GPx and GR, but renal SOD activity and GSH level were statistically insignificant as compared to control group. Subcutaneous injection of hemin (40 µmol/kg b.w. partially ameliorated CP-induced renal damage, based on suppression of blood urea, serum creatinine, the renal MDA and NO levels, and increased antioxidant capacity in CP-treated rats. The results of histopathological and ultrastructural investigations supported the renoprotective effect of hemin against CP-induced acute toxicity. Conclusion. The induction of HO-1 by hemin is a promising approach in the treatment of CP-induced nephrotoxicity. However, further preclinical studies are warranted to test effectiveness of CP/hemin on the outcome of tumor chemotherapy.

    Objective To assess the impact of the number, and time of acute rejection (AR) and outcome of anti-rejection therapy on the long-term survival of renal allografts and the relative risk factors. Methods The Kaplan-Meier analysis and log-rank test were used to calculate the survival rates of patients and grafts in no acute rejection group (NAR, 895 patients), 1 rejection episode group (1AR, 183), 2 and more than 2 rejection episodes group (2AR, 17), acute rejection group [AR (1AR+2AR), 200], early acute rejection group (within 90 days after transplantation, EAR, 125), late acute rejection group (91 days later, LAR, 58), completely AR reversed group (CAR, 105), and incompletely AR reversed group (IAR, 68). The relative risk factors were analyzed by the Cox proportional hazards regression. Results The 5- and 10-year survival rates of renal allografts were 75.4% and 17.1% in AR and 93.2% and 86.5% in the NAR group (P<0.0001). The long-term graft survival was much lower in the 2AR group than in the NAR or 1AR groups (P<0.0001 and P=0.002, respectively). It was similar in either the NAR or CAR groups (P=0.31), but it was significantly lower (P<0.0001) in the IAR group. Multivariate Cox regression analysis revealed that the outcome of anti-rejection therapy is an important risk factor affecting the long-term survival of allografts.Conclusions AR is significantly associated with poor long-term survival of renal allografts. But the long-term graft survival of patients with one acute rejection but completely reversed is not significantly different from that of patients without acute rejection.

    To determine whether the apparent benefit of revascularization of renal artery stenosis for "flash" pulmonary oedema extends to heart failure patients without a history of prior acute pulmonary oedema. A prospective study of patients with renal artery stenosis and heart failure at a single centre between 1(st) January 1995 and 31(st) December 2010. Patients were divided into those with and without previous acute pulmonary oedema / decompensation. Survival analysis compared revascularization versus medical therapy in each group using Cox regression adjusted for age, eGFR, blood pressure, and co-morbidities. There were 152 patients: 59% male, 36% diabetic, age 70 ± 9 years, eGFR 29 ± 17 mL/min/1.73 m(2) . 52 had experienced previous acute pulmonary oedema (34%), whereas 100 had no previous acute pulmonary oedema (66%). The revascularization rate was 31% in both groups. For heart failure without previous acute pulmonary oedema, the hazard ratio for death after revascularization compared to medical therapy was 0.76 (0.58-0.99, p = 0.04). In heart failure with previous acute pulmonary enema, the hazard ratio was 0.73 (0.44-1.21, p = 0.22). For those without previous acute pulmonary oedema, the hazard ratio for heart failure hospitalization after revascularization compared to medical therapy was 1.00 (0.17-6.05, p = 1.00). In those with previous acute pulmonary oedema, it was 0.51 (0.08-3.30, p = 0.48). The benefit of revascularization in heart failure may extend beyond the current indication of acute pulmonary oedema. However, findings derive from an observational study. This article is protected by copyright. All rights reserved.

  4. PHYSIOPATHOLOGY OF ACUTE RENAL FAILURE.NEW CLUES FOR AN OLD DILEMMA

    Directory of Open Access Journals (Sweden)

    Carlos G. Musso

    2008-01-01

    Full Text Available Acute renal failure (ARF is the term used to describe the sustained and abrupt reduction of the glomerular filtration, which causes the retention of waste products that come from the metabolism. Normally, the mechanisms potentially involved in ARF are divided into: pre-renal, parenchymatous, and post-renal. Regarding the etiology of the parenchymatous ARF, it would seem to be the sum of multiple pathogenic variables such as: tubular necrosis and apoptosis, alteration of the filtration barrier, retrodifusion of glomerular filtration, intrarenal vasoconstriction, contraction of the mesangium, intratubular obstruction, intersticial swelling, activation of proteolytic enzymes, and so on. Because of the above exposed data, only a multicausal perspective would seem to be adequate to understand and solve this syndrome.

    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.

    Acute renal failure was diagnosed in a German Short Haired Pointer bitch and a Kelpie cross-bred dog following envenomation by Bull ants. Both dogs had been tethered over a Bull ant nest and had experienced mass envenomation. There was local reaction at the envenomation sites and each dog had experienced vomiting that was poorly controlled by symptomatic therapy. Intensive treatment of renal failure was successful in the German Short Haired Pointer and the bitch remains well 19 months after envenomation. The Kelpie cross-bred deteriorated despite intensive treatment and was euthanased 36 hours after presentation. Necropsy examination revealed haemorrhage and necrosis of the small intestine and myocardium, bilateral nephrosis with tubular necrosis, and patchy haemorrhage of the lung alveoli, pancreas and adrenal cortices. Electron microscopy revealed necrosis of the small intestine and hydropic swelling of proximal renal tubules with necrosis of medullary tubules.

    Spontaneous renal vein thrombosis (RVT) is very rare in the absence of nephrotic syndrome. It is more common in newborns and infants. RVT should always be included in the differential diagnosis of flank pain and hematuria, and because RVT can induce acute renal injury. A 19-year-old man was admitted to our hospital because he complained of right flank pain and oliguria for 3 days. Another patient, a 24-year-old man, complained of a severe and sudden onset of bilateral flank pain and anuria for a day. They were both healthy before they developed the described symptoms and had different levels of decrease in renal function when they visited the hospital. Color Doppler ultrasonography revealed RVT in both the patients. The patients received therapy, including anticoagulation and thrombolysis, following their diagnoses, and they recovered in a few days.

    Objective: To study the clinical effect of continuous blood purification on acute renal failure. Methods: A total of 46 patients with acute renal failure treated with continuous renal replacement therapy in our hospital from April 2011 to December 2015 were retro-spectively analyzed. Patients choosing continuous veno-venous hemofiltration (CVVH) mode were collected into CVVH group and patients choosing continuous venovenous hemodiafiltration (CVVHDF) mode were collected into CVVHDF group, and their general condition, hospitalization conditions and blood biochemical indexes were analyzed. Results: Before and after treatment, the voided volumes and APACHE II scores of patients in CVVHDF group and CVVH group showed no differences. After treatment, the voided volumes of patients in the two groups were all higher than those before treatment and their APACHE II scores were all lower than those before treatment. The duration of continuous renal replacement therapy and the hospital stays in ICU of patients in CVVHDF group were all shorter than those in CVVH group. In CVVHDF group, the ratios of mechanical ventilation and death and the total hospitalization time had no sig-nificant differences with those in CVVH group. After treatment, the contents of blood urea nitrogen, serum creatinine, uric acid, β2 microglobulin, glutamic-pyruvic trans-aminase, aspartate transaminase, lactic dehydrogenase and creatine kinase isoenzyme of patients in CVVHDF group were all lower than those in CVVH group. Conclusions: Continuous blood purification therapy possesses exact curative effect on acute renal failure. The cleanup effect of CVVHDF mode on solutes and its protective effect on heart and liver were all superior to those of CVVH mode.

    1995-11-01

    Acute renal failure (ARF) commonly occurs in critically ill patients. Despite improved dialysis techniques and recent advances in intensive care medicine, mortality from this condition remains unacceptably high. Increased understanding of the factors that mediate cellular injury, such as adenosine triphosphate depletion, intracellular calcium accumulation, and generation of reactive oxygenation species, as well as those that mediate recovery, such as locally produced and systemically released growth factors, provide fresh insights that can be used to develop new strategies to limit renal damage after acute insults and speed the repair process. Exogenous administration of growth factors, adenine nucleotides, and thyroxine, each of which can facilitate recovery of experimental ARF, in addition to factors yet to be identified, is a potentially exciting new therapeutic strategy to improve survival of patients with this condition.

    We present a unique case of acute bacterial prostatitis caused by a very rare human pathogen, Raoultella planticola, in a renal allograft recipient 3.5 months post transplantation. Only a few cases of human infection by this pathogen have been reported worldwide. The present study reports the case of a 67-year-old man who was admitted to our transplant unit 3.5 months post transplantation with fever, dysuria, suprapubic pain, symptoms and signs of acute prostatitis, and elevated markers of inflammation and prostate-specific antigen. R. planticola was isolated in the urine culture. The patient was treated with ciprofloxacin (based on the antibiogram) and had a full recovery, with satisfactory renal function. To the best of our knowledge, this is not only the first reported case of R. planticola prostatitis, but also the first report of such an infection in a solid organ transplant recipient or in a patient on immunosuppressive medication.

    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.

    A 74-year-old female with acute cerebral infarction was treated with intravenous recombinant tissue plasminogen activator. Subsequent percutaneous transfemoral angiography and mechanical thrombectomy were performed due to a right middle cerebral artery occlusion, which was successfully recanalized. Two days after treatment, the patient complained of vague right abdominal pain and a laboratory test showed anemia. Abdominal computed tomography showed a right renal subcapsular hematoma. After conservative management, the patient was discharged without complications. We report a rare complication after intravenous thrombolysis in a patient with acute cerebral infarction.

    Prolonged immunosuppression in solid organ transplant recipients has been considered a risk for developing opportunistic infections and malignancies. Acute leukemia is a rare complication. We report a case of acute promyelocytic leukemia (APL) (FAB M3) after cadaveric renal transplant for focal segmental glomerulosclerosis in a 24-year-old woman. Her immunosuppressive therapy included tacrolimus, mycophenolate mofetil, and prednisone. Approximately 2 years after transplant, she became pancytopenic, prompting administration of filgrastim. A few doses caused a markedly increased blast count, resulting in a diagnosis of APL. She was successfully treated with all-trans-retinoic acid and arsenic trioxide. Myeloproliferative neoplasms after organ transplant or due to filgrastim are rare. PMID:27695174

    A non-immune, 31-year-old woman developed an acute infection with Plasmodium falciparum after travelling to Kenia. The parasites proved resistant to chloroquine and sulfadoxine/pyrimethamine. The course of the disease was complicated by acute renal failure, hepatocellular damage, disorders of blood coagulation, thrombocytopenia, hemolysis and cerebral involvement. Despite a very high level of parasitemia (50% parasitized erythrocytes) a rapid clinical improvement was achieved by plasmapheresis and hemodialysis. Our experience shows that plasmapheresis and hemodialysis are excellent additive methods which rapidly improve clinical symptoms and may reduce morbidity and mortality in severe malaria tropica.

    Objective: To investigate the protective effect of erythropoietin (EPO) pretreatment on ischemic acute renal failure in rats and its molecular mechanism. Methods: Male Sprague–Dawley rats were selected as experimental animals and they were randomly divided into the sham operation group (sham group), ischemia-reperfusion injury group (IRI group) and EPO pretreatment group (EPO group). Each group had 15 rats. Serum specimens and renal specimens were collected after a IRI model was built for 4, 12 and 24 h. The contents of creatinine, urea nitrogen tumor necrosis factor-alpha (TNF-a), interleukin-1 (IL-1), IL-6 and IL-8 in serum and the contents of TNF-a, IL-1, IL-6, IL-8, toll like receptor 4 (TLR4) and nuclear factor-kappa B (NF-kB) in the kidney tissue were determined. Results: After 4, 12 and 24 h reperfusion, there were differences between the contents of creatinine, urea nitrogen TNF-a, IL-1, IL-6 and IL-8 in serum and the contents of TNF-a, IL-1, IL-6, IL-8, TLR4 and NF-kB in rats of the three groups (P Conclusions: EPO pretreatment can protect the renal function of rats with ischemic acute renal failure by inhibiting the TLR4/NF-kB pathway mediated inflammatory responses.

  17. Rhabdomyolysis and acute renal failure after strenuous exercise and alcohol abuse: case report and literature review

    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.

    Calcineurin inhibitors such as cyclosporine A (CsA) are still commonly used after renal transplantation, despite CsA–induced nephrotoxicity (CIN), which is partly related to vasoactive mechanisms. The mineralocorticoid receptor (MR) is now recognized as a key player in the control of vascular tone, and both endothelial cell- and vascular smooth muscle cell (SMC)-MR modulate the vasoactive responses to vasodilators and vasoconstrictors. Here we tested whether vascular MR is involved in renal hemodynamic changes induced by CsA. The relative contribution of vascular MR in acute CsA treatment was evaluated using mouse models with targeted deletion of MR in endothelial cell or SMC. Results indicate that MR expressed in SMC, but not in endothelium, contributes to the increase of plasma urea and creatinine, the appearance of isometric tubular vacuolization, and overexpression of a kidney injury biomarker (neutrophil gelatinase–associated lipocalin) after CsA treatment. Inactivation of MR in SMC blunted CsA–induced phosphorylation of contractile proteins. Finally, the in vivo increase of renal vascular resistance induced by CsA was blunted when MR was deleted from SMC cells, and this was associated with decreased L-type Ca2+ channel activity. Thus, our study provides new insights into the role of vascular MR in renal hemodynamics during acute CIN, and provides rationale for clinical studies of MR antagonism to manage the side effects of calcineurin inhibitors.

    A 37-year-old woman was admitted to hospital with severe tonsillitis with unilateral necrotizing tonsillitis. She suddenly got fever, malaise, difficulties swallowing, pain in the throat and deterioration despite four days of penicillin treatment. During hospitalisation, she experienced abdominal pain, and blood tests showed pancytopenia. She was transferred to a haematological department, where a bone marrow biopsy showed acute myeloid leukaemia. Subsequently, an abdominal computed tomography with intravenous contrast revealed bilateral renal vein thrombosis, probably because of coagulopathy due to leukaemia.

    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.

    Full Text Available Gout (Podagra is a disorder of purine metabolism characterized by the deposition of monosodium urate crystals in joints and connective tissue and risk of deposition in kidney interstitium. Although acute gouty arthritis is familiar for most physicians, chronic gouty arthritis, which affects small joints of the hands can be difficult to distinguish from other common interphalangeal arthropathies such as rheumatoid arthritis (RA, psoriatic arthritis, and erosive osteoarthritis because of very similar presentations. Here we describe a 60-year-old male diabetic patient with pandigital, extensive subcutaneous tophaceous gout presented with uremic encephalopathy and joint deformities. He had been treated mistakenly as RA for 10 years.

    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.

    Full Text Available Objective : The present study was designed to investigate the ameliorative potential and possible mechanism of hydroalcoholic extract of flowers of P. granatum in glycerol-induced acute renal failure (ARF in rats. Materials and Methods : The rats were subjected to rhabdomyolytic ARF by single intramuscular injection of hypertonic glycerol (50% v/v; 8 ml/kg and the animals were sacrificed after 24 hours of glycerol injection. The plasma creatinine, blood urea nitrogen, creatinine clearance, and histopathological studies were performed to assess the degree of renal injury. Results : Pretreatment with hydroalcoholic extract of flowers of P. granatum (125 and 250 mg/kg p.o. twice daily for 3 days significantly attenuated hypertonic glycerol-induced renal dysfunction in a dose-dependent manner. BADGE (Bisphenol-A-diglycidyl ether (30 mg/kg, a peroxisome proliferator-activated receptor (PPAR-γ antagonist, and N(omega-nitro-l-arginine-methyl ester (L-NAME (10, 20, and 40 mg/kg, nitric oxide synthase inhibitor, were employed to explore the mechanism of renoprotective effects of Punica granatum. Administration of BADGE (30 mg/kg and L-NAME (40 mg/kg abolished the beneficial effects of P. granatum in glycerol-induced renal dysfunction. Conclusion : Hydroalcoholic extract of flowers of P. granatum has ameliorative potential in attenuating myoglobinuric renal failure and its renoprotective effects involve activation of PPAR-γ and nitric oxide-dependent signaling pathway.

    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.

  10. Long-term follow-up of patients after acute kidney injury: patterns of renal functional recovery.

    Etienne Macedo

    Full Text Available BACKGROUND AND OBJECTIVES: Patients who survive acute kidney injury (AKI, especially those with partial renal recovery, present a higher long-term mortality risk. However, there is no consensus on the best time to assess renal function after an episode of acute kidney injury or agreement on the definition of renal recovery. In addition, only limited data regarding predictors of recovery are available. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: From 1984 to 2009, 84 adult survivors of acute kidney injury were followed by the same nephrologist (RCRMA for a median time of 4.1 years. Patients were seen at least once each year after discharge until end stage renal disease (ESRD or death. In each consultation serum creatinine was measured and glomerular filtration rate estimated. Renal recovery was defined as a glomerular filtration rate value ≥60 mL/min/1.73 m2. A multiple logistic regression was performed to evaluate factors independently associated with renal recovery. RESULTS: The median length of follow-up was 50 months (30-90 months. All patients had stabilized their glomerular filtration rates by 18 months and 83% of them stabilized earlier: up to 12 months. Renal recovery occurred in 16 patients (19% at discharge and in 54 (64% by 18 months. Six patients died and four patients progressed to ESRD during the follow up period. Age (OR 1.09, p<0.0001 and serum creatinine at hospital discharge (OR 2.48, p = 0.007 were independent factors associated with non renal recovery. The acute kidney injury severity, evaluated by peak serum creatinine and need for dialysis, was not associated with non renal recovery. CONCLUSIONS: Renal recovery must be evaluated no earlier than one year after an acute kidney injury episode. Nephrology referral should be considered mainly for older patients and those with elevated serum creatinine at hospital discharge.

  11. 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

    Full Text Available Oxydant injury is considered to be an important mechanism in the pathophysiology of acute renal failure. It has been thought that decrease in extracellular and intracellular fluid and endotoxemia seen in obstructive jaundice may cause an increase in production of oxygen free radicals and impairment in antioxydant defense mechanism. This study is designed to investigate the possible role of oxydant injury in renal failure seen in jaundiced patients. In this study, 28 rats were divided into four groups: Control(C (N=7; Renal ischemia (RI (N=7; Obstructive jaundice+renal ischemia (OJ+RI (N=7; Obstructive jaundice (OJ (N=7. All groups were compared with each other according to renal failure findings and enzyme activities, such as Xanthine oxidase (XOD, Superoxide Dismutase (SOD and Catalase in renal cortex and Glutathione Peroxidase (GSH-Px, in blood at 3rd day after ischemia and reperfusion. Renal failure findings monitored by blood urea and creatinine levels, seemed more evident in OJ+RI than RI group (p <0.05. When compared with RI, in OJ+RI group, increase in XOD activity at 3rd day was statistically significant [0.259 ±0.01 U/g (tissue and 0.362±0.03 U/g (tissue respectively] (p <0.05. SOD and GSH-Px activities of each ischemic group at 3rd day were decreased compared to non-ischemic groups. This fall was significant (p <0.05. But there was no statistical difference between jaundiced and non-jaundiced groups. Alterations in catalase activities also had no statistical significance.

    Resistance to ischemic acute kidney injury has been shown to be higher in female rats than in male rats. We found that renal venous norepinephrine overflow after reperfusion played important roles in the development of ischemic acute kidney injury. In the present study, we investigated whether sex differences in the pathogenesis of ischemic acute kidney injury were derived from the renal sympathetic nervous system using male and female Sprague-Dawley rats. Ischemia/reperfusion-induced acute kidney injury was achieved by clamping the left renal artery and vein for 45 min followed by reperfusion, 2 weeks after contralateral nephrectomy. Renal function was impaired after reperfusion in both male and female rats; however, renal dysfunction and histological damage were more severe in male rats than in female rats. Renal venous plasma norepinephrine levels after reperfusion were markedly elevated in male rats, but were not in female rats. These sex differences were eliminated by ovariectomy or treatment with tamoxifen, an estrogen receptor antagonist, in female rats. Furthermore, an intravenous injection of hexamethonium (25mg/kg), a ganglionic blocker, 5 min before ischemia suppressed the elevation in renal venous plasma norepinephrine levels after reperfusion, and attenuated renal dysfunction and histological damage in male rats, and ovariectomized and tamoxifen-treated female rats, but not in intact females. Thus, the present findings confirmed sex differences in the pathogenesis of ischemic acute kidney injury, and showed that the attenuation of ischemia/reperfusion-induced acute kidney injury observed in intact female rats may be dependent on depressing the renal sympathetic nervous system with endogenous estrogen.

    2015-02-01

    Full Text Available Background: There appears to be a perception amongst parents and in popular literature that infantile colic is caused by feeding difficulties. Limited support for this perception is found in scientific literature. Whilst there is scientific evidence that suck, swallow and breathing are key components of successful feeding, these components and the coordination thereof in infants with colic have not been extensively researched.Objective: The objective of the study was to explore the suck, swallow and breathing coordination in infants with infantile colic and compare it with infants without the condition.Method: An assessment protocol for suck, swallow and breathing coordination was compiled from literature. This protocol was performed on a research group of 50 infants, independently diagnosed with infantile colic, and a control group of 28 infants without the condition. All participants were from two rural towns in the North–West province, South Africa, selected with a snowball selection method and strict selection criteria. The study followed a static comparison group design. Results: A significant difference in the key components of feeding and the presence of colic in participants of four age categories were found. The correlation between postural control and the presence of infantile colic were sustained in participants from 2–19 weeks old. Conclusion: Suck, swallow and breathing were found to be significantly associated with infantile colic. The findings should be investigated further. It appears that speech-language therapists may play an expanding role in infantile colic.[pdf to follow

    Full Text Available In this prospective study, we aimed to assess the clinical characteristics of acute renal failure (ARF, determine oxidative stress, as well as to predict the outcome in patients with severe falciparum malaria (FM. The study included a total of 75 subjects; there were 25 adult patients with acute severe FM and ARF, 25 adult patients with uncomplicated FM without ARF, and 25 age- and sex-matched healthy subjects who served as controls. In patients with severe FM and ARF (n = 25, renal failure was non-oliguric in 28% and oliguric in 72%. The average duration of renal failure was 10.53 ± 4.0 days. Sixty percent recovered and 40% died. All patients with non-oliguric presentation recovered. The mean serum malondialdehyde (MDA levels were 0.82 ± 0.43 μmol/L, 2.97 ± 1.11 μmol/L, and 6.86 ± 2.62 μmol/L, respectively, in healthy con-trols, in patients with uncomplicated FM, and in those with severe FM with ARF. The Acute Physiology Age and Chronic Health Evaluation II (APACHE II score, Sequential Organ Failure Assessment (SOFA score, and the Acute Tubular Necrosis-Individual Severity Index (ATN-ISI score were all significantly higher in the expired group (19 ± 5.49 when compared to the survivor group (14.4 ± 3.15 (P = 0.014. Kaplan-Meier survival analysis showed that survival was low in patients with delayed hospitalization and longer duration of symptoms. Also, we observed a high occurrence of acute respiratory distress syndrome and central nervous system involvement among the patients who expired.

    This study sought to assess the relationship between serum concentrations of the soluble ST2 (sST2) and B-type natriuretic peptide (BNP) and investigate the role of sST2 as a prognosticator in patients hospitalized with acute heart failure (HF) and renal insufficiency. sST2 was measured at admission and discharge in 66 patients hospitalized with acute decompensated HF and renal insufficiency (estimated glomerular filtration rate [eGFR] renal insufficiency (eGFR renal function, even though BNP level was much higher in patients with severe renal insufficiency. During 3 month follow-up, 9 (13.6%) died and 16 (24.2%) were readmitted due to HF aggravation.On multivariate analysis, sST2 at discharge was independently associated with death or HF readmission during 3 months after discharge (hazard ratio, 1.038; 95% confidence interval, 1.011-1.066, P = 0.006). In conclusion, sST2 is not affected by renal function compared with BNP in acute HF patients. The measurement of predischarge sST2 can be helpful in predicting short-term outcomes in acute decompensated HF patients with renal insufficiency.

    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 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.

    A randomized study of graft irradiation in the treatment of acute rejection of renal transplants was conducted from 1978 to 1981. Patients developing clinical signs of an acute graft rejection received customary antirejection treatment in the form of intravenous administration of high-dose (1 gm per day) of methylprednisolone. They were at the same time randomized to either receive therapeutic irradiation (175 rad every other day to a total of 525 rad) or sham irradiation. Neither the patient nor the Transplant Service surgeons knew at any time whether the radiation treatment had been given. Eighty-three rejection episodes occurring in 64 grafts were entered into the study. Acute rejection was reversed in 84.5% of grafts in the control and 75% in the treated group. The incidence of recurrent rejection was higher in the treated group (66 vs. 46%) and graft survival was lower (22% vs. 54%). The study failed to demonstrate a beneficial effect of graft irradiation in the treatment of acute renal allograft rejection, when used in conjunction with high dose steriods.

    Availability of a functional vascular access is a mandatory prerequisite for extracorporeal renal replacement therapy in patients with acute renal failure. The femoral site of insertion commonly is chosen because it is an easy and convenient access. However, an array of complications may substantially alter the quality of treatment, and it appears that catheter-related morbidity and dysfunction are more frequent with the femoral than internal jugular site. This study is designed to evaluate the potential benefits of using soft silicone tunneled catheters ((ST)Caths) at the femoral site. Thirty patients with acute renal failure treated by intermittent hemodialysis (IHD) and/or continuous venovenous hemodiafiltration (CVVHDF) were assigned to either twin (ST)Caths or twin polyurethane nontunneled femoral catheters. Time necessary for catheter insertion, catheter-related complications, and catheter lifespan were monitored. Catheter performance during IHD and the effect of catheter type on dialysis dose were evaluated. The time necessary for (ST)Cath insertion was significantly longer. The incidence of vein thrombosis and catheter-related infection was lower, and the ratio of venous return pressure to catheter blood flow was better with an (ST)Cath. Recirculation rates were similar for both types of catheters. Whether treated by using IHD or CVVHDF, patients with an (ST)Cath benefited from a greater delivered dialysis dose. Multivariate analysis confirmed that (ST)Cath use was a determinant factor to optimize dialysis dose delivery. (ST)Cath patency was significantly longer. In patients with acute renal failure, use of an (ST)Cath minimizes catheter-related morbidity and improves dialysis efficiency compared with conventional femoral catheters.

    Acute spontaneous tumor lysis (ASTL) syndrome, an extremely rare disease, requires prompt recognition and aggressive management because it is fulminant at its outset, associated with severe metabolic derangement, and potentially reversible. We describe an unusual case in which spontaneous tumor lysis occurred in anaplastic large T-cell lymphoma associated with acute uric acid nephropathy, persistent oliguria, and shock. This case contrasts markedly with previously reported cases of ASTL syndrome, which developed mainly in the pathologic type of Burkitt lymphoma. To our knowledge, this is the first reported occurrence of ASTL syndrome associated with anaplastic large T-cell type lymphoma. This report also chronicles our successful experience with continuous renal replacement therapy in the presence of compromised hemodynamic status.

    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

    Background: Acute kidney injury after cardiac surgery is associated with adverse in-hospital and long-term outcomes. Novel risk factors for acute kidney injury have been identified, but it is unknown whether their incorporation into risk models substantially improves prediction of postoperative acute kidney injury requiring renal replacement therapy. Methods: We developed and validated a risk prediction model for acute kidney injury requiring renal replacement therapy within 14 days after cardiac surgery. We used demographic, and preoperative clinical and laboratory data from 2 independent cohorts of adults who underwent cardiac surgery (excluding transplantation) between Jan. 1, 2004, and Mar. 31, 2009. We developed the risk prediction model using multivariable logistic regression and compared it with existing models based on the C statistic, Hosmer–Lemeshow goodness-of-fit test and Net Reclassification Improvement index. Results: We identified 8 independent predictors of acute kidney injury requiring renal replacement therapy in the derivation model (adjusted odds ratio, 95% confidence interval [CI]): congestive heart failure (3.03, 2.00–4.58), Canadian Cardiovascular Society angina class III or higher (1.66, 1.15–2.40), diabetes mellitus (1.61, 1.12–2.31), baseline estimated glomerular filtration rate (0.96, 0.95–0.97), increasing hemoglobin concentration (0.85, 0.77–0.93), proteinuria (1.65, 1.07–2.54), coronary artery bypass graft (CABG) plus valve surgery (v. CABG only, 1.25, 0.64–2.43), other cardiac procedure (v. CABG only, 3.11, 2.12–4.58) and emergent status for surgery booking (4.63, 2.61–8.21). The 8-variable risk prediction model had excellent performance characteristics in the validation cohort (C statistic 0.83, 95% CI 0.79–0.86). The net reclassification improvement with the prediction model was 13.9% (p < 0.001) compared with the best existing risk prediction model (Cleveland Clinic Score). Interpretation: We have developed

    Increased dialysis dose has been shown to improve morbidity and survival in chronic hemodialysis patients. Despite improvement in care and technological aspects of renal replacement therapy, mortality rates of acute renal failure (ARF) have remained essentially unchanged for over two decades, exceeding 50% in most studies. The occurrence of ARF in older patients with more complicated medical and surgical conditions has contributed to this lack of outcome amelioration, and death of ARF patients is now more frequently caused by underlying disease than ARF itself. A recent prospective survey at this institution found a mortality rate of 79.1% among a total of 363 ARF medical and surgical intensive care unit patients, with a mean age near 60 years and a mean admission APACHE II score of over 20, who were treated by intermittent hemodialysis and continuous renal replacement therapy (CRRT). Nonsurvivors had a mean of over four failed systems, in addition to the renal failure, compared with survivors who had less than four. The standards for dialysis adequacy in ARF are not currently defined. Increased catabolism seen in ARF patients in the intensive care unit may justify large dialysis dose delivery. An apparent influence of delivered dialysis dose on the outcome of ARF intensive care unit patients has been recently observed at our institution. Compared with nonsurvivors, survivors had received significantly higher dialysis dose, as assessed by Kt/V and urea reduction ratio. In ARF patients, the discrepancy between delivered versus prescribed dialysis dose may be particularly important and contributed to by the following: reduced blood flow rate and dialysis time consequent to patient intolerance; lower dialyzer in vivo clearances, particularly in heparin-free dialysis; blood recirculation when using temporary vascular access; and postdialysis urea rebound. Prolonging the course of renal failure is one of the risks attributed to frequent dialysis; hypotension and

  9. Changing picture of renal cortical necrosis in acute kidney injury in developing country.

    Renal cortical necrosis (RCN) is characterized by patchy or diffuse ischemic destruction of all the elements of renal cortex resulting from significantly diminished renal arterial perfusion due to vascular spasm and microvascular injury. In addition, direct endothelial injury particularly in setting of sepsis, eclampsia, haemolytic uremic syndrome (HUS) and snake bite may lead to endovascular thrombosis with subsequent renal ischemia. Progression to end stage renal disease is a rule in diffuse cortical necrosis. It is a rare cause of acute kidney injury (AKI) in developed countries with frequency of 1.9%-2% of all patients with AKI. In contrast, RCN incidence is higher in developing countries ranging between 6%-7% of all causes of AKI. Obstetric complications (septic abortion, puerperal sepsis, abruptio placentae, postpartum haemorrhage and eclampsia) are the main (60%-70%) causes of RCN in developing countries. The remaining 30%-40% cases of RCN are caused by non-obstetrical causes, mostly due to sepsis and HUS. The incidence of RCN ranges from 10% to 30% of all cases of obstetric AKI compared with only 5% in non-gravid patients. In the developed countries, RCN accounts for 2% of all cases of AKI in adults and more than 20% of AKI during the third trimester of pregnancy. The reported incidence of RCN in obstetrical AKI varies between 18%-42.8% in different Indian studies. However, the overall incidence of RCN in pregnancy related AKI has decreased from 20%-30% to 5% in the past two decades in India. Currently RCN accounts for 3% of all causes of AKI. The incidence of RCN in obstetrical AKI was 1.44% in our recent study. HUS is most common cause of RCN in non-obstetrical group, while puerperal sepsis is leading cause of RCN in obstetric group. Because of the catastrophic sequelae of RCN, its prevention and aggressive management should always be important for the better renal outcome and prognosis of the patients.

    Cerebral small-vessel disease (SVD) is associated with renal dysfunction such as chronic kidney disease. Although cerebral microbleeds (CMBs) are common in patients with acute lacunar infarcts (ALI), the association between renal dysfunction and CMBs in such patients remains unclear. Between April 2007 and March 2013, we evaluated consecutive first-ever ALI patients, who were admitted to our hospital within 24 hours of stroke onset. CMBs were defined as focal areas of signal loss in brain parenchyma less than 5 mm on T2(∗)-weighted gradient-echo imaging. Renal dysfunction was defined as an estimated glomerular filtration rate less than 60 mL/minute/1.73 m(2) on admission. Correlations between renal dysfunction and the presence (model 1) and location of CMBs (model 2; any deep or infratentorial CMBs) were determined by multivariable logistic regression analyses. Among 152 patients (33.6% men; mean age, 67.6 years), 53 had CMBs. Patients with CMBs were older (69.9 versus 66.3 years, P = .03) and had a higher frequency of white matter hyperintensity (WMH; 62.3% versus 25.3%, P CMBs. On multivariable analyses, renal dysfunction (odds ratio, 95% confidence interval; model 1: 2.38, 1.02-5.66; model 2: 2.78, 1.16-6.81), WMH (3.87, 1.76-8.80; 3.72, 1.64-8.71), SLI (3.85, 1.71-9.14; 4.20, 1.77-10.8), and diabetes mellitus (.26, .09-.63; .24, .08-.63) were independently associated with CMBs. In patients with ALI, renal dysfunction was positively associated with CMBs independent of cerebral SVD. Copyright © 2015 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Acute hepatitis A (AHA) is one of the most common infectious diseases; it is usually a self-limiting disease affecting the liver. Although extrahepatic manifestations are not common, some cases have been reported associated with acute renal failure. We reviewed the clinical features of patients with AHA complicated by acute renal failure (ARF group) and compared them with patients with noncomplicated AHA (non-ARF group). The medical records of 208 consecutive patients with AHA who were diagnosed between January 2003 and October 2008 were reviewed. We identified 15 patients (7.2%) with ARF associated with AHA. There were no differences between the ARF and non-ARF group with regard to gender and age. The peak value of alanine aminotransferase (ALT) (median: 6060 IU/L vs 1792 IU/L, P hepatic failure, and two patients died because of fulminant hepatic failure. There were no deaths among patients with noncomplicated AHA in the non-ARF group. Five patients underwent kidney biopsy; two patients were diagnosed with acute tubular necrosis, two patients with acute interstitial nephritis with IgA nephropathy and one patient with acute tubulointerstitial nephritis. All patients in the ARF group had microscopic haematuria and proteinuria (100%vs 31.1%, P < 0.001). Urine sodium levels were more than 10 mEq/L in 10 patients. The findings of high urinary sodium concentrations, microscopic haematuria and proteinuria did not support the diagnosis of hepatorenal syndrome (HRS). Patients with AHA with ARF had higher ALT levels, more prolonged PTs, and higher total bilirubin levels. The prognosis for these patients was poorer than for those without ARF. However, the patients with ARF and nonfulminant AHA had recovered with proper treatment and should not be confused with patients that have HRS.

    We undertook a combined retrospective and prospective analysis of duplex Doppler examinations performed over a perion of 10 months in order to assess the value of Doppler study(DS)in evaluating renal allograft dysfunction. A total of 110 DS on 82 transplant patients were performed including 79 normal transplants, 29 acute rejections and 2 acute tubular necrosis(ATN). Resistive Index(RI) in 79 normal transplants ranged from 0.44 to 0.7 (Mean;0.59+0.07) in the arcuate artery, and from 0.45 to 0.75(mean;0.61+0.08) in the interlobar artery. RI in 29 cases of acute rejection ranged from 0.61 to 1.0 (mean; 0.77+0.10) in the interlobar artery. In ATNRI ranged from 0.59 to 0.63 (mean 0.62) in the arcuate artery, and from 0.59 to 0.62(mean 0.61) in the interlobar artery. The RI in acute rejection is significantly higher than that of the normal transplants (p<0.001). With a resistive index greater than 0.8, 100% positive predictive value was obtained for the diagnosis of acute rejection. The value less than 0.7 was unlikely to suggest acute rejection(negative predictive value 92%)

    We report on a male patient with Tuberous Sclerosis Complex (TSC), which was prenatally diagnosed. At the age of 3 months the patient developed acute renal failure with excessive hyperuricemia. Kidney function improved after rehydration and application of rasburicase, however without full recovery. Due to the inappropriate high levels of uric acid compared to kidney function, screening of hypoxanthine-guanine phosphoribosyltransferase (HPRT) related diseases was initiated. Mutation analysis revealed a deletion of exon 2 and 3 of the HPRT gene confirming the diagnosis of Lesch-Nyhan Disease (LND). After initiation of allopurinol therapy renal function further improved. In the following months the patient developed clinically a typical neurological phenotype of LND and TSC with seizures, severe dystonia and developmental delay. Acute renal failure is a rare complication of HPRT related diseases. Combination of two inherited diseases may lead to a delayed diagnosis due to a mixed and maybe misleading phenotype.

    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.

    Full Text Available Objective: to study the effectiveness of some types of semipermeable dialysis membranes and replacement therapy techniques in patients with isolated acute renal failure (iARF. Subjects and methods: Eighty-nine patients aged 24 to 67 years, who received intensive and replacement/maintenance therapy, were examined. The patients were divided into 3 groups in accordance with their condition rated by the APACHE III scale, from the used dialysis membranes and renal replacement/maintenance therapy options. Results. By varying the permeability of a membrane, its area and the volume of convection, we can control the rate of substance elimination, which is similar to that of test markers having a molecular weight of 100 to 15000 Da. Conclusion. Adequate replacement therapy for iARF is possible only when high-flux, high-permeability dia-lyzers are applied. The indices of hemodialysis/hemodiafiltration adequacy in terms of urea cannot be determinants in patients with iARF. The achievement of elimination of low-molecular-weight proteins — markers of uremic intoxication to 30—35% and/or an increase in effective albumin concentrations as a summary marker of toxicity by 16—20% is of much more importance. Key words: isolated acute renal failure, uremic toxins, hemodialysis, hemodiafiltration.

    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.

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.

    Pregnancy-associated acute kidney injury (PAKI) is encountered frequently in developing countries. We evaluated the maternal, fetal and renal outcomes in women with PAKI who needed at least one session of dialysis. Of the total of 98 cases (mean age 28.85 ± 5.13 years; mean parity 2.65 ± 1.28) of PAKI, the most common cause of PAKI was postabortal sepsis. Eighteen patients died; those with oligoanuria, sepsis and central nervous system (CNS) involvement were at greater risk of mortality. The relative risk (RR) of neonatal mortality was lower after with full-term delivery (RR: 0.17, 95% confidence interval (CI): 0.03-0.96, P = 0.02) compared to preterm delivery. Of the 80 surviving patients, 60 (75%) patients achieved complete recovery of renal function at the end of 3 months; and of the remaining 14 had presumed (n = 4) or, biopsy-proven (n = 10) acute patchy cortical necrosis. The RR of non-recovery of renal function was high (RR: 24.7, 95% CI: 3.4- 179.5) in patients who did not recover at 6 weeks. Of the 14 patients with cortical necrosis, 3 (21.42%) became independent of dialysis at 6 months. PAKI patients should be watched for dialysis independency for 6 months.

    Full Text Available O ateroembolismo é uma doença multisistêmica que afeta vários órgãos, entre os quais o rim, através da liberação de êmbolos de colesterol de uma placa aterosclerótica erosada, ocasionando obstrução vascular em diversos tecidos. A doença renal ateroembólica (DRAE, histologicamente representada por cristais de colesterol nas arteríolas do rim acompanhados de um infiltrado inflamatório perivascular, é causa de insuficiência renal aguda muitas vezes grave e prolongada, que ocorre semanas ou mesmo meses após o episódio embólico. A DRAE apresesenta prognóstico ruim com elevada mortalidade. Apresentamos neste relato o caso de um paciente com DRAE que se manifestou clinicamente dois meses após a realização de um cateterismo cardíaco seguido de uma angioplastia coronária. A prevalência, manifestações clínicas, histologia renal, tratamento e o prognóstico da DRAE são discutidos.Atheroembolism is a multisytemic disease which affects many organs, including the kidneys, by the release of cholesterol emboli to tissues from an erosed atherosclerotic plaque, causing vascular obstruction in many tissues. The atheroembolic renal disease (AERD is histologically represented by cholesterol crystals in renal arterioles with an inflammatory infiltrate around the vessels, and causes acute renal failure that may be severe and prolonged, weeks or even months after the embolic episode. The AERD carries a bad prognosis, with a high mortality. We herein report a case of a patient presenting AERD which was manifested two months after he was submitted to a cardiac catheterism and coronary angioplasty. The prevalence, clinical findings, renal histology, treatment and prognosis of AERD are discussed.
