Acute tubulointerstitial nephritis (ATIN) is a common cause of acute kidney injury. Although haematuria is a risk factor for the development of renal disease, no previous study has analyzed the significance of haematuria in ATIN. Retrospective, observational analysis of 110 patients with biopsy-proven ATIN was conducted. Results: Haematuria was present in 66 (60%) ATIN patients. A higher percentage of ATIN patients with haematuria had proteinuria than patients without haematuria (89.4% vs. 59.1%, p = 0.001) with significantly higher levels of proteinuria (median (interquartile range) protein:creatinine ratio 902.70 (513–1492) vs. 341.00 (177–734) mg/g, p <0.001). Moreover, those patients with more haematuria intensity had a higher urinary protein:creatinine ratio (1352.65 (665–2292) vs. 849.60 (562–1155) mg/g, p = 0.02). Those patients with higher proteinuria were more likely to need renal replacement therapy (22.7 vs. 0%, p = 0.03) and to suffer relapse (4 vs. 0%, p = 0.03). At the end of follow up, haematuric ATIN patients had higher serum creatinine levels (3.19 ± 2.91 vs. 1.91 ± 1.17 mg/dL, p = 0.007), and a trend towards a higher need for acute dialysis (7 vs. 1%, p = 0.09) and renal replacement therapy (12.1 vs. 2.3%, p = 0.12). Haematuria is common in ATIN and it is associated with worse renal function outcomes.

Abstract Background Acute kidney injury is a major challenge for today’s healthcare systems around the globe. Renal replacement therapy has been shown to be beneficial in acute kidney injury, but treatment highly depends on the cause of the acute kidney injury. One less common cause is tubulointerstitial nephritis, which comes in different entities. A very rare type of tubulointerstitial nephritis is tubulointerstitial nephritis and uveitis syndrome, in which the patient presents with additional uveitis. Case presentation A 19-year-old caucasian male presented with mild dyspnea, lack of appetite, weight loss, and moderate itchiness. Lab results showed an acute kidney injury with marked increase of serum creatinine. The patient was started on prednisolone immediately after admission. As the patient in this case showed symptoms of uremia on admission, we decided to establish renal replacement therapy, which is unusual in tubulointerstitial nephritis and uveitis syndrome. During his course of dialysis, the patient developed symptoms of sepsis probably due to a catheter-related infection requiring intensive care and antibiotic treatment, which had to be terminated early as the patient developed a rash. Intensified immunosuppression, combined with antibiotics, significantly resolved excretory kidney dysfunction. Conclusions Since both the primary inflammatory process and the secondary infectious complication significantly impaired excretory kidney function, kidney function of younger individuals with new-onset anterior uveitis should be monitored over time and during follow-up.

<b><i>Background/Aim:</i></b> This study mainly aimed to explore the therapeutic effects of 3 renal replacement therapy (RRT) modalities on acute kidney injury (AKI) caused by wasp stings. <b><i>Methods:</i></b> A retrospective study from September 2016 to December 2019 was conducted. Thirty-one patients with AKIs caused by wasp sting were selected and divided into 3 groups according to the initial RRT modality received, namely, (1) the intermittent hemodialysis combined with hemoperfusion (IHD + HP) group, (2) the continuous veno-venous hemodiafiltration (CVVHDF) group, and (3) the CVVHDF combined with HP (CVVHDF + HP) group. The laboratory results were measured and analyzed before treatment on the 3rd, 7th, and 14th days of treatment. The renal function outcomes and survival of the patients were investigated at 3 months follow-up. <b><i>Results:</i></b> The laboratory results of enzyme measures and inflammatory indicators in wasp sting patients increased significantly in the early stage and 3 RRT modalities were effective in reducing these indicators. In addition, continuous RRT modality (CVVHDF and CVVHDF + HP) showed better clearance of myoglobin than IHD + HP. The serum creatinine levels of patients in the 3 groups did not recover to baseline within 14 days after beginning treatment. Nevertheless, the CVVHDF + HP group was better than the CVVHDF group, and CVVHDF was better than the IHD + HP group on the 3rd day. The interleukin (IL)-6 and IL-10 levels in CVVHDF + HP and IHD + HP groups were obviously lower than those in the CVVHDF group on the 3rd day. In the follow-up study, the recovery rate of renal function in CVVHDF and CVVHDF + HP groups was significantly better than that in the IHD + HP group. <b><i>Conclusion:</i></b> Early RRT was effective in the treatment of patients with A KI caused by wasp sting. CVVHDF + HP and CVVHDF modalities were better than the IHD + HP group in venom clearance and renal function recovery.

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 Acute kidney injury is a common sequela after major burn injury, but only a small proportion of patients need renal replacement therapy. In the majority of patients, need for renal replacement therapy subsides before discharge from the burn center but limited literature exists on long-term outcomes. A few studies report an increased risk for chronic renal failure after burn injury. We investigated the long-term outcome of severely burned patients receiving renal replacement therapy during acute burn injury treatment. Data on 68 severely burned patients who received renal replacement therapy in Helsinki Burn Centre between November 1988 and December 2015 were collected retrospectively. Thirty-two patients survived and remained for follow-up after the primary hospital stay until December 31, 2016. About 56.3% of discharged patients were alive at the end of follow-up. In 81.3% of discharged patients, need for renal replacement therapy subsided before discharge. Two patients received renal replacement therapy for longer than 3 months; however, need for renal replacement therapy subsided in both patients. One patient required dialysis several years later on after the need for renal replacement therapy had subsided. This study showed that long-term need for renal replacement therapy is rare after severe burn injury. In the vast majority of patients, need for renal replacement therapy subsided before discharge from primary care. Acute kidney injury in association with burns is a potential but small risk factor for later worsening of kidney function in fragile individuals.

INTRODUCTION: Acute kidney injury (AKI) is the sudden loss of renal function with accumulation of nitrogenous waste compounds. In developing countries, community acquired AKI is common than AKI in hospitalized septic patients. With conservative management many patients recover renal function however few require renal support with intermittent Hemodialysis (HD). We conducted a study to find out the etiology and outcome of the patients presenting with AKI who required dialysis.METHODS: This is a descriptive follow up study of the patients who needed renal replacement therapy in the form of HD presenting to our Nephrology unit of the hospital over a period of two years. Patients were followed up for three months post discharge. Data were tabulated and analyzed using SPSS software.RESULTS: Total 50 patients were included in study with 67% male. The commonest etiologies were urinary tract infection (30%) and  acute gastroenteritis (24%).The mean creatinine at the time of nephrology consultation, maximum level and at the time of discharge were 6.5(SD± 2.62), 7.3(SD ±2.13) and 2.2(SD ±1.75) respectively. Uremia with anuria was the most common reason for the initiation of HD in 54% cases. The mean number of intermittent HD used was 3.36. Complete recovery was seen in 68%, death in 26% and CKD in 6%.CONCLUSION: UTI followed by acute gastroenteritis are the leading cause of AKI in our tertiary level hospital. Timely initiated renal replacement therapy in the form of intermittent HD could lead to substantial renal recovery in almost three fourth of patients.

Malignancy or its treatment affect kidney in several ways. The most common are acute kidney injury and chronic kidney disease. Other form of kidney diseases can also be present such as nephrotic syndrome, tubulointerstitial nephritis, thrombotic microangipathy etc. In addition, electrolyte abnormalities such as hypercalcemia, hyponatremia and hypernatremia, hypokalemia and hyperkalemia, and hypomagnesemia. are observed. Treatment of malignancy associated kidney disease is usually symptomatic. Cessation of the offending agent or other supportive measures if needed i.e. renal replacement therapy are also implemented.

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.

Abstract Background: The previous study demonstrated that there were no significant differences between saline and balanced crystalloid solution infused in critical illness. However, the sepsis subgroup analysis showed the statistical difference. Thus, we will specifically focus on septic patients in this study to compare the effects of saline and balanced solution. We hypothesize that effects of saline on acute kidney injury (AKI) are related to the underline AKI severity and total volumes of infusion. Methods/design: The investigators designed a pragmatic, multi-centered crossover trial recruiting 312 patients who are diagnosed as sepsis/septic shock in the intensive care unit (ICU) and will be assigned with either acetate Ringer's solution or saline in the corresponding month. Patients with an end-stage renal disease (ESRD) or who need renal replacement therapy (RRT) prior to or at the time of enrollment are excluded. Enrolled patients will be regarded as with mild, moderate or severe sepsis on the basis of the severity of their illness, and will be divided into subgroups according to their initial renal function and various intravenous infusion volumes when being analyzed. The primary outcome is major adverse kidney events (MAKE), including the composite of in-hospital death, receipt of new renal replacement therapy, or persistent renal dysfunction. Secondary outcomes include 28 days-mortality, internal environment disturbance, incidence and duration of vasoactive drug treatment, duration of mechanical ventilation, duration of RRT and ICU and hospital length of stay. Results and Conclusions: To our knowledge, this study will be the first to focus on septic patients and provide credible and evident data on the comparison of outcome between acetate Ringer’s solution and saline for intravenous infusion in adult septic patients on the basis of baseline renal function and infusion volumes taken into consideration.

Abstract Background and Aims Acute kidney injury (AKI) is a frequent complication after cardiac surgery. Its incidence ranges from 19 to 44% depending on the study and which definition is used. There are some well-known risk factors associated with AKI, including baseline patient characteristics (age and comorbidities), need of perioperative blood transfusion or presence of previous chronic kidney disease. We wanted to evaluate if a nephrologist management and control of potential risk factors of renal disease can be used to prevent AKI, thereby minimizing the risk of need RRT, reducing costs and improving survival in these patients. It will be the first study focused on this intervention. The aim of this study is to assess if a nephrology intervention before cardiac surgery can reduce the postoperative incidence of AKI. Method Unicentric prospective randomized controlled trial of 298 participants from 2015 to 2019. The inclusion criteria was patients undergoing scheduled cardiac surgery of &gt; 18 years old. The exclusion criteria was a requirement for renal replacement therapy before surgery. Clinical Research Ethics Committee of Bellvitge has approved the study before initiation. All patients have given written informed consent. We have done an intention-to-treat analysis, continuous variables have been compared between groups using Student's t test and categorical variables using X2. Results Nephrology intervention before surgery, included a preoperative study done minimum 1 month before the surgery to optimize the patient’ s overall condition by optimization of hydration state, remove or minimize dose of drugs that potentially deteriorate kidney function and correct metabolic disorders. No differences in the characteristics of the patients between groups was found (Table 1). The number of patients with AKI were 49 without differences between groups (0.112), with most of them presenting a stage 1 AKI, only 3 patients present a stage 3 AKI, but none of them required renal replacement therapy (Table 2). We found 1.3% of mortality (1 participant in the intervention group and 3 in control group). Data at 1 year follow-up (n= 144) showed low incidence of kidney disease (creatinine in intervention arm 91.87±30.79μmol/L and in control arm 87.08±23.58, p=0.292) without differences in albuminuria. Conclusion In summary, we did not find any difference in acute kidney injury and death when a nephrology intervention is done to cardiac surgery patients, probably it would be necessary to increase the sample size to make conclusions. The results at 1 year follow-up showed no kidney disease in these patients.
