Rhabdomyolysis is diagnosed based on the levels of blood biomarkers such as creatine kinase (CK), but the use of CK levels to predict long-term renal function remains controversial. This current report presents a case with a very high CK level with the presentation of acute kidney injury (AKI) who regained full renal function. A 29-year-old man, in a manic mood and presenting with dyspnoea, was admitted to hospital following an episode of ketamine use along with a history of drug abuse. The laboratory analyses identified rhabdomyolysis (CK, 35 266 U/l) and AKI (serum creatinine, 3.96 mg/dl). Despite treatment with intravenous normal saline (4000 ml/day), his CK level reached at least 300 000 U/l. He underwent 13 sessions of haemodialysis and his renal function fully recovered. The final measurements were serum creatinine 1.0 mg/dl and CK 212 U/l. These findings support the view that the predictive power of CK level on AKI is limited, especially regarding long-term renal function. Close follow-up examinations of renal function after haemodialysis are mandatory for patients with rhabdomyolysis.

Abstract Background COVID-19 infection manifests as pneumonia associated with multiple organ failure, and death. Acute kidney injury is a risk factor for mortality. There is limited scientific literature on COVID-19 infection and allergic tubulointerstitial nephritis, its clinical course and short- and long-term prognosis. Method We performed a retrospective study where medical records of 60 patients with histological diagnosis of allergic tubulointerstitial nephritis from January 2009 to November 2020. In these patients, we studied the incidence of COVID-19 infection, clinical characteristics and prognosis from March to the actual date. Results Of 60 patients with allergic tubulointerstitial nephritis, 6 (10%) patients were diagnosed with COVID-19. The first case, an 85-year-old woman with a history of metastatic melanoma treated with nivolumab and allergic tubulointerstitial nephritis by immunobiological agents in 2018, diagnosed with mild COVID-19 infection in April 2020 without deterioration of renal function in controls at 3 and 6 months of follow-up. The second case, a 51-year-old woman with a history of large B-cell lymphoma with plasmacytic differentiation and progression to multiple myeloma of lambda light chains and allergic tubulointerstitial nephritis due to chemotherapy since 2019, admitted for acute pyelonephritis and PRES syndrome secondary to first dose of bortezomib complicated with COVID-19 nosocomial pneumonia and acute pancreatitis treated with corticosteroids and broad spectrum antibiotic therapy; she died of abdominal refractory septic shock. The third patient, a 64-year-old man without prior renal impairment, was admitted for severe COVID-19 pneumonia and acute kidney injury secondary to acute tubulointerstitial nephritis of uncertain etiology that required orotracheal intubation and continuous veno-venous hemodiafiltration for a week who received methylprednisolone in bolus for 3 days and continued treatment with corticosteroid therapy with complete recovery of renal function and improvement in proteinuria at 3 months of follow-up. The fourth patient, an 82-year-old woman with acute kidney injury AKIN 3 secondary to acute allergic tubulointerstitial nephritis related to ciprofloxacin complicated with severe COVID-19 nosocomial pneumonia, who died despite ventilatory support and high-dose steroids therapy and tocilizumab. The fifth patient, a 75-year-old with a history of metastatic lung adenocarcinoma treated with immunobiological agents and allergic tubulointerstitial nephritis in  2018, admitted in march 2020 for mild COVID-19 pneumonia treated with steroids and hydroxychloroquine without deterioration of respiratory and kidney function.  The sixth patient, an 86-years-old man with acute kidney injury AKIN 3 due to acute allergic tubulointerstitial nephritis secondary to proton-binding inhibitors and nosocomial COVID-19 infección with improvement of kidney function with steroids therapy only.  Conclusion Our 6 patients with allergic tubulointerstitial nephritis and COVID-19 infection presented different spectrum of the disease. It seems that nosocomial COVID-19 infection in patients admitted with recent diagnosis of acute allergic tubulointerstitial nephritis presented a worse clinical prognosis compared with long-term diagnosed acute tubulointerstitial nephritis. Further studies with a larger sample size are needed.

ABSTRACT Introduction: preeclampsia can be associated with future renal disease. Objectives: To measure changes in renal function overtime in patients with preeclampsia. Methods: urine and serum samples from eleven patients with preeclampsia and eight patients with a normal pregnancy were obtained during pregnancy, postpartum, and 3 years after delivery. Urine podocalyxin, protein, and serum creatinine were measured. Results: after 3 years, there were no significant differences in urinary podocalyxin in patients with or without preeclampsia: 4.34 ng/mg [2.69, 8.99] vs. 7.66 ng/mg [2.35, 13], p = 0.77. The same applied to urinary protein excretion: 81.5 mg/g [60.6, 105.5] vs. 43.2 mg/g [20.9, 139.3] p = 0.23. Serum creatinine was 0.86 mg/dL [0.7, 0.9] vs. 0.8 mg/dL [0.68, 1] p = 0.74 in those with and without preeclampsia. In normal patients, urinary podocalyxin decreased from 54.4 ng/mg [34.2, 76.9] during pregnancy to 7.66 ng/mg [2.35, 13] three years after pregnancy, p = 0.01. Proteinuria decreased from 123.5 mg/g [65.9, 194.8] to 43.2 mg/g [20.9, 139.3], p = 0.12. In preeclampsia patients, urinary podocalyxin decreased from 97.5 ng/mg [64.9, 318.4] during pregnancy to 37.1 ng/mg within one week post-partum [21.3, 100.4] p = 0.05 and 4.34 ng/mg [2.69, 8.99] three years after, p = 0.003. Proteinuria was 757.2 mg/g [268.4, 5031.7] during pregnancy vs. 757.2 mg/g [288.2, 2917] postpartum, p = 0.09 vs. 81.5 mg/g [60.6, 105.5] three years later, p = 0.01. Two patients still had proteinuria after 3 years. Conclusions: in preeclampsia patients, postpartum urinary podocalyxin decreased before proteinuria. After three years, serum creatinine, urinary podocalyxin, and protein tended to normalize, although some patients still had proteinuria.

Abstract Background and Aims Acute Kidney Injury (AKI) is an important determinant of outcome in hospitalized patients. Further, there is a risk for development of Chronic Kidney Disease (CKD) in the future. Though the long-term impact of AKI has been studied in developed countries, there is a paucity of data in this area from the Indian subcontinent. This single-centre study aimed to assess the pattern, clinical spectrum, short-term and long-term outcomes of AKI. Method In this prospective observational cohort study, detailed demographic and clinical data at presentation, during hospital stay and follow-up at 1, 3, 6 and 12 months after discharge were obtained prospectively for a cohort of patients with AKI. Both community (CAAKI) and hospital acquired AKI (HAAKI) were included. Patient with pre-existing CKD were excluded. Outcome variables examined were in-hospital mortality, renal function at discharge and on follow-up after discharge from hospital. Results In our study cohort with 476 patients, majority of the cases were CAAKI (395, 83%). The mean age at presentation was 44.8 ± 18.7 years. Medical causes (84%) contributed to the majority of AKI while the remaining were due to surgical (10%) and obstetrical (6%) causes. Sepsis (176/476; 36.9%) was the most common cause of AKI. The most common source for sepsis was respiratory (41%) followed by urological source (18.7%). The in-hospital mortality rate for patients with AKI was 38%. Age >60 years (HR = 1.51; 95% CI, 1.11 – 2.07), oliguria (HR = 1.48; 95% CI, 1.05 – 2.10), need for ventilator (HR = 2.45; 95% CI, 1.36 – 4.41) and/or inotropes (HR = 14.4; 95% CI, 6.28 – 33.05) were predictors of mortality. At discharge, 146 (30.7%) patients had complete renal recovery, while 149 (31.3%) had partial renal recovery. Oliguria (p < 0.001), hypoalbuminemia (p = 0.001) and need for renal replacement therapy (RRT) (p = 0.01) were significantly associated with partial recovery. Of the 295 patients on follow-up at discharge, 211 (71.5%) patients had normal renal function, 4 (1.4%) died and 33 (11.2%) were lost to follow up; 47(15.9%) patients developed CKD of which 6 (2%) were dialysis dependent. Elderly patients, higher AKIN stage with oliguria and those requiring RRT were more likely to develop CKD. Among these, the need for in-hospital RRT was the single most important factor predicting the risk of CKD (OR 1.77, 95% CI, 1.12-2.78). Conclusion In conclusion, our data shows that AKI in hospitalized patients still has high mortality in emerging countries like India. Though a fairly good percentage of cases recovered, there is a definite risk of CKD development, especially in patients who required RRT during hospitalization.

Bilimbi/belembu fruit belongs to the family of Oxalidacae, species Averrhoa bilimbi. Freshly prepared concentrated juice of bilimbi has very high oxalic acid content and consumption carries a high risk of developing acute kidney injury (AKI) by deposition of calcium oxalate crystals in renal tubules. AKI due to Averrhoa bilimbi juice injestion is very rare. We report the case history of a 60-year-old hypertensive, dyslipidemic patient, with normal renal function, who ingested around 600ml of juice in fasting state for treating dyslipidemia. The patient developed AKI and required three sessions of hemodialysis. Her renal function returned to normal after five weeks.Bangladesh Crit Care J September 2015; 3 (2): 71-73

Background. Severe acute kidney injury (AKI) among hospitalized patients often necessitates initiation of short-term dialysis. Little is known about the long-term outcome of those who recover to normal renal function. The aim of this study was to determine the long-term renal outcome of patients experiencing AKI requiring dialysis secondary to hypoperfusion injury and/or sepsis who recovered to apparently normal renal function. Methods. All adult patients with AKI requiring dialysis in our centre between 1 January 1980 and 31 December 2010 were identified. We included patients who had estimated glomerular filtration rate (eGFR) >60 mL/min/1.73 m2 12 months or later after the episode of AKI. Patients were followed up until 3 March 2015. The primary outcome was time to chronic kidney disease (CKD) (defined as eGFR persistently <60 mL/min/1.73 m2) from first dialysis for AKI. Results. Among 2922 patients with a single episode of dialysis-requiring AKI, 396 patients met the study inclusion criteria. The mean age was 49.8 (standard deviation 16.5) years and median follow-up was 7.9 [interquartile range (IQR) 4.8–12.7] years. Thirty-five (8.8%) of the patients ultimately developed CKD after a median of 5.3 (IQR 2.8–8.0) years from first dialysis for AKI giving an incidence rate of 1 per 100 person-years. Increasing age, diabetes and vascular disease were associated with higher risk of progression to CKD [adjusted hazard ratios (95% confidence interval): 1.06 (1.03, 1.09), 3.05 (1.41, 6.57) and 3.56 (1.80, 7.03), respectively]. Conclusions. Recovery from AKI necessitating in-hospital dialysis was associated with a very low risk of progression to CKD. Most of the patients who progressed to CKD had concurrent medical conditions meriting monitoring of renal function. Therefore, it seems unlikely that regular follow-up of renal function is beneficial in patients who recover to eGFR >60 mL/min/1.73 m2 by 12 months after an episode of AKI.

Introduction: At present, we are witnessing an increase in preeclampsia, especially the most severe forms, which are associated with an increased risk of maternal-perinatal morbidity and mortality. As a severity criterion, acute kidney injury (AKI) has been associated with a worse prognosis, and for this reason, the maternal and perinatal variables associated with AKI in patients with severe preeclampsia (SP) were analysed in this study. Methods: An observational, retrospective, single-centre study of patients with SP treated at a tertiary hospital between January 2007 and December 2018 was conducted. The case criteria based on the criteria established by the ACOG Practice Guidelines for Gestational Hypertension and Preeclampsia. AKI is considered when serum creatinine exceeds 1.1 mg/dL in a pregnant woman with previously normal renal function. In patients with existing chronic kidney disease (CKD), it is referred to as AKI if the baseline serum creatinine increases by 1.5 fold. Pregestational, gestational and postpartum variables were analysed up to 12 weeks postpartum using univariate and multivariate logistic regression analysis. Results: During the study period, 76,828 births were attended, and 303 pregnant women were diagnosed with SP. The annual incidence of SP increased gradually throughout the study period, reaching 1.79/100 births/year in 2018. Acute kidney injury (AKI) occurred in 24.8% of the patients. The multivariate analysis revealed an increased association with a history of previous CKD, the use of assisted reproductive techniques and caesarean section. Uric acid and thrombotic microangiopathy (TMA) had a high correlation with AKI. Indications for caesarean section are associated with AKI in SP. Regarding perinatal outcomes in cases of AKI, there was a higher percentage of neonates who required foetal lung maturation with steroids and an increased need for NICU admission. No case of maternal death was recorded; however, an increase in neonatal mortality was found among patients who did not develop AKI. After 12 weeks postpartum, 72 patients were referred to the nephrology consultation for persistent hypertension, proteinuria or renal failure. Conclusions: In preeclampsia, AKI is a common complication, especially among patients with a history of CKD, those who became pregnant using assisted reproduction techniques and those who delivered via caesarean section. The perinatal impact of AKI is mainly centred on a higher rate of NICU admission and a lower mortality rate. Among biochemical and haematological markers, the uric acid level prior to renal failure has a direct and significant correlation with the risk of AKI, as does the development of TMA in patients with preeclampsia. Therefore, the monitoring of renal function in cases of preeclampsia should be strict, and referral for a nephrology consultation may be necessary in some cases.

Background. The real impact of septic shock-associated acute kidney injury (AKI) on the long-term renal outcome is still debated, and little is known about AKI-burn patients. In a cohort of burn survivors treated by continuous renal replacement therapy (CRRT) and sorbent technology (CPFA-CRRT), we investigated the long-term outcome of glomerular and tubular function. Methods. Out of 211 burn patients undergoing CRRT from 2001 to 2017, 45 survived, 40 completed the clinical follow-up (cumulative observation period 4067 months, median 84 months, IR 44-173), and 30 were alive on 31 December 2020. Besides creatinine and urine albumin, in the 19 patients treated with CPFA-CRRT, we determined the normalized GFR by 99mTc-DTPA (NRI-GFR) and studied glomerular and tubular urine protein markers. Results. At the follow-up endpoint, the median plasma creatinine and urine albumin were 0.99 (0.72–1.19) and 0.0 mg/dL (0.0–0.0), respectively. NRI-GFR was 103.0 mL/min (93.4–115). Four patients were diabetic, and 22/30 presented at least one risk factor for chronic disease (hypertension, dyslipidemia, and overweight). Proteinuria decreased over time, from 0.47 g/day (0.42–0.52) at 6 months to 0.134 g/day (0.09–0.17) at follow-up endpoint. Proteinuria positively correlated with the peak of plasma creatinine (r 0.6953, p 0.006) and the number of CRRT days (r 0.5650, p 0.035) during AKI course, and negatively with NRI–GFR (r −0.5545, p 0.049). In seven patients, urine protein profile showed a significant increase of glomerular marker albumin and glomerular/tubular index. Conclusions. Burn patients who experienced septic shock and AKI treated with CRRT had a long-term expectation of preserved renal function. However, these patients were more predisposed to microalbuminuria, diabetes, and the presence of risk factors for intercurrent comorbidities and chronic renal disease.

Background. Acute kidney injury (AKI) is a common complication of cardiac surgery but its long-term consequences, in patients with chronic kidney disease (CKD), are not known.Methods. We compared the long-term prognoses of CKD patients who developed (n=23) and did not develop (n=35) AKI during the period of hospitalization after undergoing coronary artery bypass graft (CABG). Fifty-eight patients who survived (69.6±8.4years old, 72% males, 83% Whites, 52% diabetics, baseline GFR:46±16 mL/min) were followed up for47.8±16.4months and treated for secondary prevention of events.Results. There were 6 deaths, 4 in the AKI+ and 2 in the AKI− group (Log-rank = 0.218), two attributed to CV causes. At the end of the study, renal function was similar in the two groups. One AKI− patient was started on dialysis. Only 4 patients had an increase in serum creatinine ≥ 0.5 mg/dL during follow-up.Conclusion. CKD patients developing AKI that survived the early perioperative period of coronary intervention present good renal and nonrenal long-term prognosis, compared to patients who did not develop AKI.

Abstract Introduction:Acute kidney injury (AKI) and chronic kidney disease (CKD) affect 10-70% of transplant recipients. Onset of kidney injury varies from days to months or years after transplantation. Kidney injury may be caused by multiple factors. Long-term data on cyclosporine induced nephrotoxicity post HSCT are limited. It is unclear if cyclosporine induced nephrotoxicity at early phase post HSCT will impact long term renal function. The objective of this study is to evaluate the progression of renal function in allogeneic hematopoietic stem cell transplant (HSCT) patients, before, during and after cyclosporine therapy. Methods:This is a retrospective single arm cohort study evaluating the impact of cyclosporine on renal function in patients who underwent allogeneic HSCT from 2003 through 2013. Patients age≥ 14 years who underwent allogeneic HSCT and received cyclosporine as graft-versus-host disease (GVHD) prophylaxis and alive two years post HSCT without disease relapse or GVHD were included in the study. Primary outcome was the change in serum creatinine and estimated creatinine clearance. Delta creatinine (baseline creatinine - creatinine on day 25, day 100, day 180, year 1 and year 2 post HSCT) was used to calculate the change in the serum creatinine and estimated creatinine clearance. Estimated creatinine clearance was calculated using Cockcroft and Gault formula (CG) for patients aged ≥ 18 years. Schwartz formula was used to estimate creatinine clearance for patients aged ≥ 14 years till 18 years. The secondary outcome was the incidence of acute kidney injury. AKI was defined as per RIFLE criteria. The severity grades were defined on the basis of the changes in serum creatinine. CKD was defined if estimated glomerular filtration rate (GFR) <60 ml/minute per 1.73 m2 for 3 months. All patient during the study period were screened. Descriptive statistics were used to describe the data, continuous variables were reported as mean ± stander deviation and categorical variables were summarized as frequencies and percentages. The study was approved by the Office of Research Affairs in our institution. Results: Out of 912 patients who underwent allogeneic HSCT from 2003 to 2013, 121 patients were included who met the inclusion criteria listed above in the method section (Figure 1). The majority of patients were males (55%) with sever aplastic anemia as primary disease (31%). Mean baseline serum creatinine was 52±16 µmol/l, mean baseline estimated creatinine clearance was 116±58 ml/minute per 1.73 m2 (Table 1). Mean duration of cyclosporine levels monitoring was 232±180 days. Serum creatinine increased from the baseline at day 25, day 100, day 180, 1 year and 2 years post HSCT (Mean± SD; 45.7 ±39, 66.2 ±45.9, 37.8±27.1, 31.9±22.55, 28±22.5 µmol/l, respectively) (Figure 2). This translated into reductions in the estimated creatinine clearance at day 25, day 100, day 180, 1 year and 2 years post HSCT (Mean± SD; -61.6±51 , -89.6 ±55.7,-67. ±55.34,-62.5±55.4,-57.6±56.ml/minute per 1.73 m2, respectively) (Figure 3). The highest incidence of AKI was at day 100 post HSCT in the included patients. 40% of them had supratherapeutic cyclosporine levels. There was association between developing acute kidney injury at day 100 and CKD at 2 years post HSCT, 23% of the included patients had acute kidney injury and 13 % of them found to have CKD at 2 years post HSCT as illustrated table 2. Conclusion:Our study demonstrated that cyclosporine represents a primary risk factor for progression of renal impairment in hematopoietic stem cell transplant recipients particularly in those who developed acute kindly injury at 100 days. Disclosures No relevant conflicts of interest to declare.

History Of

A 66-year-old women with no history of renal disease was admitted due to a coma and acute kidney injury with a serum creatinine level of 7.44 mg/dL which were ascribed to valacyclovir neurotoxicity and nephrotoxicity, respectively. She had received valacyclovir at a standard dosage for the treatment of herpes zoster and was finally discharged, having fully returned to her normal baseline mental status with a recovered serum creatinine level of 0.68 mg/dL. We feel that awareness of this pathology remains a challenge for physicians and therefore strongly recommend the further accumulation of experiences similar to our own. Our experience underscores the pitfalls of administering valacyclovir to elderly patients who barely appear to have a favorable renal function. Several concerns regarding the therapeutic management, including blood purification strategies, that emerged in this case are also discussed.
