Abstract Introduction Patients with post-operative hypoparathyroidism mostly require Calcium supplements and Calcitriol with goal of maintaining calcium levels in low normal range. However, calcium balance can further be dysregulated by other factors including renal failure in patients with otherwise stable levels. We present a case of recurrent symptomatic hypercalcemia leading to multiple hospital visits in a patient with otherwise stable longstanding post-operative hypoparathyroidism that was precipitated after episode of Acute Renal Failure. Case Presentation 71 Year old male with past medical history of Atrial fibrillation, Hypertension, Primary Hyperparathyroidism status post Parathyroidectomy (Parathyroid hyperplasia with removal of 3/12 glands) in 2003 with subsequent Hypoparathyroidism presented with lethargy and confusion few days after cardioversion attempt for atrial fibrillation. He was noted to have bradycardia and hypotension post procedure which improved subsequently. His medications included Calcitriol 0.25 mcg twice daily and Calcium Carbonate 1.25 grams twice daily. His Calcium had remained stable over the years on this regimen. On presentation, he was found to have elevated corrected calcium of 12.5 mg/dl and Acute Renal failure with Creatinine of 8.3 mg/dl which was normal 1 week prior. He underwent hydration and subsequently required few sessions of hemodialysis with improvement in kidney function and further hemodialysis was not needed. On discharge his corrected calcium was 8.6 mg/dl and Creatinine was 3.9 mg/dl. His Calcitriol and Calcium were resumed on discharge. However, 3 weeks later he presented again with lethargy and calcium was again elevated at 14.8 mg/dl. All other workup for hypercalcemia including PTHRP, Bone marrow biopsy, Serum electrophoresis were negative. Subsequently, he had 2 more admissions for hypercalcemia and 1 admission for hypocalcemia within 1 month. Finally his calcium levels stabilized with reduced dose of Calcitriol and Calcium with close weekly monitoring initially as outpatient. Discussion In advancing kidney disease, the kidneys are no longer able to increase urine calcium excretion, and this removes an important safety mechanism to prevent calcium excess in patients with Chronic kidney disease. In patients with hypoparathyroidism on Calcitriol and Calcium supplements, renal failure may offset the calcium balance leading to dysregulation and erratic levels with increased tendency towards hypercalcemia. Conclusion Acute Renal Failure may lead to hypercalcemia in patients with otherwise stable levels. However, limited understanding of calcium balance/ regulation in renal failure, especially in setting of hypoparathyroidism further complicates the situation and may lead to difficult titration of medications.

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.

Acute renal failure and chronic kidney disease are more common in HIV-infected patients compared with the general population. Several studies have shown age to be a risk factor for HIV-associated kidney disease. The improved life expectancy of HIV-infected patients as a result of widespread use of antiretroviral therapy has resulted in progressive aging of HIV cohorts in the developed world, and an increased burden of cardiovascular and kidney disease. Consequently, HIV care increasingly needs to incorporate strategies to detect and manage these non-infectious co-morbidities.

The 24-hour urine proteinuria or albuminuria ratio is still prescribed for protein detection in urine, despite the fact that it has been replaced by the albuminuria or protein/creatininuria ratio. The use of this ratio eliminates the misinterpretation of 24-hour urine proteinuria. The objective of this development is to clarify the importance of the ratio for the search for albumin or protein in the urine. We conducted a review of the literature focusing on different diagnostic recommendations. Indeed, 24-hour urine collection is tedious and prone to many errors. The ratio is therefore a simple, reliable and standardized indicator for assessing proteinuria except in acute renal failure patients. The correlation between these ratios and 24-hour urine has been demonstrated in several studies in various populations and is currently considered to be the most adequate measure for proteinuria quantification despite the variability in creatinine excretion. The Kidney Disease Improving Global Outcomes recommendations therefore suggest the use of the albumin/creatinine ratio and the protein/creatinine ratio on a 1st morning urine sample to test for proteinuria.

Background: The CHADS-VASC score does not incorporate renal dysfunction in stroke risk assessment in patients with atrial fibrillation and the prevalence of atrial fibrillation, atrial flutter, and cerebrovascular accidents (CVA) in patients with concurrent CHF and CKD is not well investigated. Objective: Evaluate the prevalence of history of stroke, atrial fibrillation, atrial flutter in patients with CHF and CKD. Methods: Data from the single institution Get With The Guidelines- Heart Failure (GWG-HF) cohort of 2938 consecutive inpatients with known GFR was utilized. CHADS-VASC score was calculated from the GWG-HF variables. Chronic kidney disease (CKD) was defined as GFR <60 ml/min. Results: An overwhelming majority (95%) of GWG-HF patients had elevated >1 CHADS-VASC score, which was also significantly more common in patients with CKD (97.6% vs. 91.7% in patients without CKD, p<0.0001). Average CHADS-VASC score was also significantly increased in patients with CKD (4+/-1.3 vs. 3.3+/-1.4, p<0.0001). Furthermore, CKD was associated with increased prevalence of atrial fibrillation and/or flutter (45.6% vs. 35.3%, p<0.0001) and stroke history (17.5% vs. 12.3%, p=0.002). When stroke and TIA histories were removed from the CHADS-VASC score ("CHAD-VASC score"), the remaining variables were strongly predictive of stroke or TIA (14.2% vs. 3.8%, p<0.0001). In multivariate logistic regression analysis, both CHAD-VASC score (OR 2.6, 95%CI 1.3-5.4, p=0.009) and CKD (OR 1.5, 95%CI 1.2-1.8, p=0.001) were associated significantly increased odds of prior stroke or TIA. Conclusions: In patients admitted with heart failure, CKD is associated with increased prevalence of atrial fibrillation or atrial flutter as well as increased prevalence of CVA/TIA. Further prospective studies are warranted to examine whether CKD history should be included in stroke risk assessment in patients with atrial fibrillation or atrial flutter, in conjunction with existing risk assessment frameworks.

ABSTRACT Given the shortage of organs transplantation, some strategies have been adopted by the transplant community to increase the supply of organs. One strategy is the use of expanded criteria for donors, that is, donors aged >60 years or 50 and 59 years, and meeting two or more of the following criteria: history of hypertension, terminal serum creatinine >1.5mg/dL, and stroke as the donor´s cause of death. In this review, emphasis was placed on the use of donors with acute renal failure, a condition considered by many as a contraindication for organ acceptance and therefore one of the main causes for kidney discard. Since these are well-selected donors and with no chronic diseases, such as hypertension, renal disease, or diabetes, many studies showed that the use of donors with acute renal failure should be encouraged, because, in general, acute renal dysfunction is reversible. Although most studies demonstrated these grafts have more delayed function, the results of graft and patient survival after transplant are very similar to those with the use of standard donors. Clinical and morphological findings of donors, the use of machine perfusion, and analysis of its parameters, especially intrarenal resistance, are important tools to support decision-making when considering the supply of organs with renal dysfunction.

Abstract Background and Aims Crystal-induced kidney disease refers to kidney injury caused by intratubular crystal deposition. The most common forms of crystalline nephropathy encountered in renal pathology are nephrocalcinosis and oxalate nephropathy. The purpose of our study is to determine the epidemiological and clinical characteristics of hyperoxaluria diagnosed from renal biopsy. Method We retrospectively reviewed all kidney biopsy specimens evaluated at renal pathology laboratory, from 1976 to 2019. The biopsy specimens were received from multiple medical department and medical centers. We studied 8900 biopsy specimens and we were focused on patients whose diagnosis of hyperoxaluria was made from renal biopsy Results We identified 25 cases (15 children and 10 adults) with a sex ratio H / F of 0.9. Mean age at diagnosis was 17.2 years old [4 months-73 years old]. Most patients were offspring of consanguineous mating (14 of 25) with intermarriage of first-degree cousins being the most common pattern. A family history of chronic kidney disease was found in 13 patients: indeterminated nephropathy (n = 6) and renal stone (n = 5) and primary hyperoxaluria (n=2). Among our patients, five had a history of urolithiasis. One patient had a history of chronic diarrhea related to Crohn's disease and one patient had a history of cephalic pancreatectomy and ileal resection. Initial symptoms and signs were dominated by renal failure (n = 25) with mean creatinine of 789.5 μmol / l [306-1832μmol / l], associated with proteinuria in 10 patients and hematuria in 11 patients. Arterial hypertension was present in 4 patients. Oligo anuria was reported in 4 patients without dilation of the urinary excretory pathways. In our patients, the diagnosis of crystalin nephropathy was revealed by renal biopsy. In one case, the diagnosis was made after renal transplant. In 4 cases the diagnosis was made by postmortem kidney biopsy. In all cases, the kidney biopsy specimen showed extensive intratubular crystal deposition and tubulointerstitial mononuclear cell infiltration with features of tubular injury and interstitial fibrosis. Examination of histologic slides showed colorless refractile crystals of polygonal appearance. Multicolored birefringence under polarized light identified these crystals as calcium oxalate. After different investigations (genetic and biological analysis), the diagnosis of hyperoxaluria was confirmed. Hyperoxaluria was primary in 23 patients and secondary in 2 patients. Conclusion Hyperoxaluria is a rare condition, often serious, involving renal prognosis and sometimes life-threatening, especially in early-onset forms. Early diagnosis and treatment should be done as soon as possible to slow the progression to end-stage renal failure. In patients with renal insufficiency, the diagnosis of hyperoxaluria is difficult. Renal biopsy can help when clinical and radiological data are not sufficient.

Bilateral hydronephrosis secondary to urinary obstruction leads to a buildup of back pressure in the urinary tract and may lead to impairment of renal function. We present a case of a 57-year-old male with a history of alcoholic liver cirrhosis, who presented with tense ascites and acute renal failure. Bilateral hydronephrosis was seen on abdominal ultrasound. Multiple large-volume paracenteses resulted in resolution of hydronephrosis and prompt improvement in renal function.

e22104 Background: Risk of acute renal failure (ARF) among breast cancer (BC) patients may increase with nephrotoxic chemotherapy and other exposures, but this risk is not well characterized. Furthermore, among patients who present with renal insufficiencies (RI) at cancer diagnosis, subsequent treatment patterns are not well described. Methods: We performed a retrospective cohort study using a large national commercial claims database. The cohort included all women diagnosed with BC from 2000 to 2007 who were 18–64 years at diagnosis with no history of cancer (n=13,296). We defined a diagnosis of BC as at least one inpatient or two outpatient claims more than 30 days apart with an ICD-9 code of 174. Among patients with no history of RI (n=13,150), we calculated the cumulative incidence (CI) of ARF_the proportion with at least one inpatient or two outpatient claims with an ICD-9 code of 584 or 586 in the first year following cancer diagnosis. Treatment for BC patients with a history of RI (n=146) was also assessed. Results: Among BC patients with no history of RI, 0.3% were diagnosed with ARF within a year after cancer diagnosis. The CI of ARF was higher in patients with metastases: 0.7% for any metastasis, 2.3% for bone metastasis, and 0.1% for no metastasis. The CI of ARF among patients undergoing radiation or mastectomy was similar to the overall rate (0.3%) but was higher in patients receiving nephrotoxic chemotherapy (1.0%) or intravenous bisphosphonates (IV BPs) (2.1%). The CI of ARF was higher in patients with congestive heart failure (1.4%), diabetes (0.9%), and/or hypertension (0.8%) at cancer diagnosis compared to patients without these comorbidities (0.2%). Among BC patients with a history of RI, 7.5% were administered nephrotoxic chemotherapy, 30.1% received potentially nephrotoxic chemotherapy, and 1.4% were given IV BPs. Conclusions: Breast cancer patients who present with comorbidities, develop metastases, or are given nephrotoxic chemotherapy or IV bisphosphonates are at higher risk of acute renal failure in the first year after breast cancer diagnosis. More research is warranted on the treatment of breast cancer patients with a history of renal insufficiency. [Table: see text]
