Hypotension and peritoneal dialysis

Emphysematous cystitis (EC) is a relatively rare condition characterized by gas formation in the bladder wall and/or lumen. We report a case of emphysematous cystitis with a bladder perforation in an 84-year-old male on peritoneal dialysis who presented with fever, dysuria, hematuria, and hypotension. Gas in the bladder wall, as well as a small perforation in the roof of the urinary bladder, was seen on the abdominal CT scan. The causative organism identified was Escherichia coli. The patient recovered with broad-spectrum antibiotics along with bladder irrigation and drainage...

Blood pressure changes upon standing reflect a hemodynamic response, which depends on the baroreflex system and euvolemia. Dysautonomia and fluctuations in blood volume are hallmarks in kidney failure requiring replacement therapy. Orthostatic hypotension has been associated with mortality in hemodialysis patients, but neither this relationship nor the impact of changes in blood pressure has been tested in patients on peritoneal dialysis. We investigated both these relationships in a cohort of 137 PD patients...

Infants with acute kidney injury (AKI) who are critically ill often will have multiorgan dysfunctions. Objective of the present study was to find out mortality, recovery of kidney function at discharge and at 3 months, and to determine risk factors for mortality. Fifty-two infants (24 newborns and 28 postneonatal) with AKI were included. Staging was done as per Kidney Disease Improving Global Outcomes classification. Patients were subjected to medical treatment and peritoneal dialysis (PD), wherever indicated...

Acute kidney injury (AKI) complicates up to 50% of left ventricular assist device (LVAD) placements and up to 30% of these patients require dialysis. Despite advances in LVAD technology since the first-generation devices, the risk for AKI remains high. We present a case of a woman in her 50s with previously stable stage C heart failure who developed critical cardiogenic shock and resultant AKI. She required continuous kidney replacement therapy both before and after placement of an LVAD. Following multiple inpatient and outpatient hemodialysis sessions complicated by hypotension, she was transitioned to peritoneal dialysis (PD)...

OBJECTIVES: To compare different modalities of renal replacement therapy in critically ill adults with acute kidney injury. DATA SOURCES: We searched Medline, PubMed, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov from inception to 25 May, 2020. We included randomized controlled trials comparing the efficacy and safety of different renal replacement therapy modalities in critically ill patients with acute kidney injury. STUDY SELECTION: Ten reviewers (working in pairs) independently screened studies for eligibility, extracted data, and assessed risk of bias...

BACKGROUND: Intradialytic hypotension (IDH) remains the most frequent severe side effect of hemodialysis (HD) and increases patient morbidity and mortality. Excessive ultrafiltration (UF) is considered the leading cause of IDH. This study developed a suitable prescription of UF to reduce the incidences of IDH episodes. METHODS: A retrospective study was performed to analyze 33,224 HD/hemodiafiltration (HDF) treatments in 312 patients. The prescription of UF were determined following the International Society of Peritoneal Dialysis (ISPD) guideline...

We present the case of a 42-year-old male with a history of type-2 diabetes mellitus (complicated by end-stage renal disease on peritoneal dialysis) and chronic diarrhea was admitted to the emergency department due to an exacerbation in the number of evacuations.

Carnitine is a naturally occurring amino acid derivative that is involved in the transport of long-chain fatty acids to the mitochondrial matrix. There, these substrates undergo β-oxidation, producing energy. The major sources of carnitine are dietary intake, although carnitine is also endogenously synthesized in the liver and kidney. However, in patients on dialysis, serum carnitine levels progressively fall due to restricted dietary intake and deprivation of endogenous synthesis in the kidney. Furthermore, serum-free carnitine is removed by hemodialysis treatment because the molecular weight of carnitine is small (161 Da) and its protein binding rates are very low...

Uremic pericarditis and pericardial effusion are possible complications among patients with end-stage renal disease. The accumulation of toxic metabolites may contribute to the pathogenesis of uremic pericarditis. Bleeding diathesis in peritoneal dialysis patients raises the risk of hemorrhagic pericardial tamponade, which is a fatal complication of peritoneal dialysis. We report a case of hemorrhagic pericardial tamponade who was nonadherent to peritoneal dialysis with initial presentation of hypotension and syncope...

PURPOSE: This network meta-analysis aims to compare the efficacy and safety of various renal replacement therapy (RRT) modalities in critically ill patients with acute kidney injury (AKI). MATERIALS AND METHODS: We searched the electronic databases for randomized controlled trials (RCTs) comparing different RRT modalities, including continuous RRT, intermittent RRT, hybrid RRT, and peritoneal dialysis (PD), in critically ill patients with AKI through July 26, 2020...

Selenium is essential for human health; its deficiency leads to cardiac dysfunction. We herein report a 79-year-old man on peritoneal dialysis who presented with refractory hypotension caused by selenium deficiency. He was admitted to our hospital with bacterial pneumonia and hypotension and abnormal electrocardiogram (ECG) findings. Despite improvement of pneumonia, his hypotension continued, and intravenous noradrenalin could not be discontinued. His serum selenium level was extremely low, and he was started on intravenous selenium...

Background: The efficacy of intravenous (IV) ferric carboxymaltose (FCM) has been demonstrated in haemodialysis and non-dialysis studies, but evidence is lacking in patients undergoing peritoneal dialysis (PD). Methods: This multicentre, retrospective study evaluated the effectiveness and safety of FCM in patients on PD over 12 months. We retrospectively reviewed the electronic medical records of PD patients who initiated FCM treatment between 2014 and 2017 across seven Spanish centres...

Hypotension, blood pressure fluctuation, and endothelial impairment indicate possible additive pathophysiological aspects in the development of posterior reversible encephalopathy syndrome in children on peritoneal dialysis.

The COVID-19 pandemic has greatly affected nephrology. Firstly, dialysis patients appear to be at increased risk for infection due to viral transmission next to an enhanced risk for mortality as compared to the general population, even in the face of an often apparently mild clinical presentation. Derangements in the innate and adaptive immune systems may be responsible for a reduced antiviral response, whereas chronic activation of the innate immune system and endothelial dysfunction provide a background for a more severe course...

Although the frequency of pregnancy in women on chronic dialysis is extremely low, it is associated with severe maternal and perinatal morbidity and mortality. This situation represents a challenge for the therapeutic team, which requires multidisciplinary management, as well as measures to adequate dialysis treatment. Such efforts include increasing the time and frequency of dialysis session, maintaining low uremia levels and ensuring hemodynamic stability by avoiding intra-treatment arterial hypotension and hydro electrolytic fluctuations...

A 65-year-old woman was hospitalized for heart failure and pneumonia in a nearby hospital. She had been previously diagnosed as light chain (AL) amyloidosis and treated with melphalan plus dexamethasone (Mel-Dex), and lenalidomide plus dexamethasone (Len-Dex). She started treatment including antimicrobials and diuretics, but her renal function worsened progressively, and she was transferred to our hospital for nephrological care. She was treated with antimicrobials, noradrenaline, dobutamine, and continuous hemodiafiltration...

Background: Peritonitis remains a major complication in peritoneal dialysis (PD). Abdominal imaging is often performed in the setting of peritonitis to evaluate for concomitant intra-abdominal processes. However, the usefulness of this procedure is unknown. Objective: The aim of this study was to assess the prevalence of abdominal imaging performed in the setting of PD peritonitis and to evaluate clinical parameters associated with abnormal imaging results to identify clinical situations in which radiographic examinations are informative...

BACKGROUND We present the possibility of successful peritoneal dialysis (PD) treatment in acute kidney injury (AKI) patients with multiple comorbidities. CASE REPORT A 60-year-old woman with chronic kidney disease (CKD, stage G3b), liver cirrhosis (Child-Pugh class A score), and thrombocytopenia developed AKI due to urosepsis. Laboratory tests showed serum creatinine 430.5 µmol/L, urea 44.0 mmol/L, potassium 5.7 mmol/L, C-reactive protein 208 mg/L, procalcitonin 8 ng/mL, platelets 14×10⁹/L, hemoglobin 5...

BACKGROUND: Calcium channel blockers (CCBs) are used to manage hypertension which is highly prevalent among people with chronic kidney disease (CKD). The treatment for hypertension is particularly challenging in people undergoing dialysis. OBJECTIVES: To assess the benefits and harms of calcium channel blockers in patients with chronic kidney disease requiring dialysis. SEARCH METHODS: We searched the Cochrane Kidney and Transplant Register of Studies to 27 April 2020 through contact with the Information Specialist using search terms relevant to this review...

Renal tubular dysgenesis (RTD) is a rare fatal disorder in which there is poor development of proximal tubules, leading to oligohydramnios and the Potter sequences. RTD occurs secondary to renin-angiotensin system (RAS) blockade during the early stages of fetal development or due to autosomal recessive mutation of genes in the RAS pathway. A boy born at 33+1 weeks due to cord prolapse was found to be anuric and hypotensive. Pregnancy was complicated by severe oligohydramnios from gestational age 28+4 weeks...
