Hyponatremia in kidney injury

BACKGROUND: Diclofenac is the non-steroidal anti-inflammatory drug (NSAID) mostly prescribed worldwide, but it is highly associated with hypertension and acute kidney injury. Despite that, little information is available about the renal effects of diclofenac in hypertensive individuals, which led us to carry out this comparative study between the renal effects of this NSAID in normotensive (NTR) and spontaneously hypertensive rats (SHR). METHODS: Male Wistar NTR and SHR were orally treated with vehicle (V: 10 mL/kg) or diclofenac sodium (D: 100 mg/kg) once a day for 3 days...

Treatment of severely hyponatremic patients with continuous renal replacement therapy (CRRT) presents a unique challenge given the lack of commercial options for hypotonic replacement solutions or dialysate. We report the case of a 55-year-old male who presented with profound, symptomatic hyponatremia in the setting of acute kidney injury (AKI). The patient was found to have a serum sodium concentration of 97 mEq/L because of free water retention that occurred during severe AKI from viral gastroenteritis and rhabdomyolysis...

OBJECTIVES: Midodrine, an oral α-1-adrenergic receptor agonist, counters arterial hypovolemia and reduces complications in adult patients with cirrhosis. This randomized controlled trial (RCT) aimed to assess the efficacy and safety of midodrine in preventing complications and improving survival in children with cirrhosis and ascites who are awaiting liver transplantation (LT). METHODS: This open-label RCT conducted from January 2022 to May 2023 included children under 18 years with cirrhosis and ascites...

BACKGROUND: On February 6th, 2023, two consecutive earthquakes struck southeastern Türkiye with magnitudes of 7.7 and 7.6, respectively. This study aimed to analyze the clinical and laboratory findings, as well as management of pediatric victims with Crush Syndrome (CS) and Acute Kidney Injury (AKI). METHODS: The study included pediatric earthquake victims who were presented to Mersin University Hospital. Clinical and laboratory characteristics of the patients were collected retrospectively...

BACKGROUND: Diagnostic codes are commonly used as inputs for clinical prediction models, to create labels for prediction tasks, and to identify cohorts for multicenter network studies. However, the coverage rates of diagnostic codes and their variability across institutions are underexplored. The primary objective was to describe lab- and diagnosis-based labels for 7 selected outcomes at three institutions. Secondary objectives were to describe agreement, sensitivity, and specificity of diagnosis-based labels against lab-based labels...

The maintenance of fluid and electrolyte homeostasis by the kidney requires proper folding and trafficking of ion channels and transporters in kidney epithelia. Each of these processes requires a specific subset of a diverse class of proteins termed molecular chaperones. One such chaperone is GRP170, which is an Hsp70-like, endoplasmic reticulum (ER)-localized chaperone that plays roles in protein quality control and protein folding in the ER. We previously determined that loss of GRP170 in the mouse nephron leads to hypovolemia, electrolyte imbalance, and rapid weight loss...

Maintenance intravenous fluids are the most frequently ordered medications for hospitalized children. Since the American Association of Pediatrics published national guidelines, there has been an increased reflexive use of isotonic solutions, especially 0.9% saline, as a prophylaxis against hyponatremia. In this educational review, we discuss the potential deleterious effects of using 0.9% saline, including the development of hyperchloremia, metabolic acidosis, acute kidney injury, hyperkalemia, and a proinflammatory state...

As Odisha is an endemic region for malaria with many acute kidney injury (AKI) cases, this study evaluated the clinical profile and treatment outcomes of patients with malaria complicated by AKI. This prospective observational study was conducted between December 2015 and September 2017. Detailed histories and clinical examinations were recorded. On admission, tests for routine hematology, plasma glucose, liver function, renal function, serum electrolytes, thick smears, thin smears, and malarial parasites were performed...

INTRODUCTION: Clinical guidelines recommend monitoring for metabolic derangements while on preventive pharmacologic therapy for kidney stone disease. The study objective was to compare the frequency of side effects among patients receiving alkali citrate, thiazides, and allopurinol. METHODS: Using claims data from working-age adults with kidney stone disease (2008-2019), we identified those with a new prescription for alkali citrate, thiazide, or allopurinol within 12 months after their index stone-related diagnosis or procedure...

OBJECTIVE: Almost two thirds of the world's aneurysmal subarachnoid hemorrhage (aSAH) are in low- and middle-income countries. Herein, we aimed to evaluate the impact of complications on the outcome of aSAH in a middle-income country. METHODS: Baseline data (age, sex, World Federation of Neurosurgical Society, time ictus-treatment, treatment modality) and medical and neurologic complications from a cohort in Brazil (2016-2019) were evaluated: delayed cerebral ischemia; hydrocephalus; meningitis; seizures; intracranial hypertension; infections (pneumonia, bloodstream, urinary tract infection infection of undetermined source); sodium disturbances; acute kidney injury; and cardiac and pulmonary complications...

BACKGROUND AND OBJECTIVES: Human albumin (HA) solution is currently recommended only for patients with spontaneous bacterial peritonitis (SBP) and acute kidney injury (AKI). However, its use in hospitalized patients is quite frequent. The objective was to compare the outcomes of patients receiving HA in recommended (Gr. A) vs. non-recommended (Gr. B) indications. METHODS: In this prospective study, consecutive hospitalized patients who received HA were included...

We describe a case of a 28-year-old male who presented with general malaise, fatigue, anorexia, occasional epigastric pain, and vomiting a few days after a mild severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Clinical evolution led to weight loss (6 kg in six months) and craving for salty foods. Physical examination revealed dehydration, hypotension, and hyperpigmentation of the skin and mucosal surfaces. Laboratory tests demonstrated normocytic normochromic anemia, acute kidney injury, hyperkalemia, hyponatremia, and compensated metabolic acidosis...

OBJECTIVE: We aimed to investigate the frequency of dysnatremia among patients admitted with COVID-19 infection and its association with inpatient mortality. METHODS: This retrospective longitudinal study was conducted for 12 weeks. Serum sodium levels were recorded at admission, during the hospital stay, and within 48 hours of discharge or death. Logistic regression was used to determine the predictors of mortality. RESULTS: This study included 574 patients (69...

BRASH syndrome, characterized by bradycardia, renal failure, atrioventricular (AV) blockage, shock, and hyperkalemia, is an emerging clinical entity that challenges healthcare practitioners. This case report presents a unique instance of BRASH syndrome with an atypical presentation in a 56-year-old woman with a past medical history of hypertension, diabetes, and chronic kidney disease. Initial laboratory results revealed severe normocytic anemia, thrombocytopenia, renal dysfunction, acidosis, and hyponatremia, alongside hyperkalemia and hypothyroidism...

Plasmodium knowlesi ( Pk ) causes zoonotic malaria and is known as the "fifth human malaria parasite". Pk malaria is an emerging threat because infections are increasing and can be fatal. While most infections are in Southeast Asia (SEA), especially Malaysia, travelers frequently visit this region and can present with Pk malaria around the world. So, clinicians need to know (1) patients who present with fever after recent travel to SEA might be infected with Pk and (2) Pk is often misdiagnosed as P. malariae (which typically causes less severe malaria)...

Hypernatremia (plasma sodium > 145 mmol/L) reflects impaired water balance, and affected patients can suffer from severe neurologic symptoms. Hyponatremia, on the other hand, is the most frequent electrolyte disorder in hospitals. It may be diagnosed in acute kidney injury (AKI), but hyponatremia prior to the diagnosis of AKI has also predictive or prognostic value in the short term. Aim of the article was to summarize data on both, epidemiology and outcomes of in-hospital acquired hypernatremia ("In-hospital acquired" refers to the diagnosis of either hypo- or hypernatremia in patients, who did not exhibit any of these electrolyte imbalances upon admission to the hospital)...

BACKGROUND: Mamushi bites are the most common venomous snake bites in Japan, with known complications including rhabdomyolysis and acute kidney injury; however, adrenal insufficiency as a result of snake bites has not been previously reported. We report a case of empty sella with transient adrenal insufficiency during hospitalization for a Mamushi bite. CASE PRESENTATION: An 84-year-old man was admitted to our hospital with a Mamushi bite on the right fifth finger...

BACKGROUND: Colistin, a cationic polypeptide antibiotic of the polymyxin class has come back into use due to its potent antimicrobial activity against multidrug-resistant gram-negative bacteria and the lack of new antibiotics. The purpose of this study was to assess the critically ill infants treated with colistin in our neonatal intensive care unit and to identify predisposing factors for the emergence of acute kidney injury (AKI) following colistin treatment. METHODS: This was a retrospective case-control study that included infants with proven or suspected nosocomial infections in the neonatal intensive care unit of a University Hospital between January 2012 and March 2022...

Myxedema coma is a rare and life-threatening manifestation of severe hypothyroidism. Myxedema refers to altered mental status observed in these patients. Clinical characteristics observed include hypothermia, bradycardia, respiratory failure, hyponatremia, and altered mental status. We present the case of a 57-year-old female who was brought into the hospital with a history of collapse and a long lie. On initial assessment, she was hypothermic, hypotensive, bradycardic, and hypoglycemic with elevated infection markers, acute kidney injury, and electrolyte derangement...

OBJECTIVE: SARS-CoV-2 causes acute respiratory disease, interstitial and alveolar pneumonia, and involves numerous organs and systems such as the kidney, heart, digestive tract, blood, and nervous system. We aimed to evaluate the incidence of renal manifestations in patients diagnosed with COVID-19 infection. PATIENTS AND METHODS: We performed a monocentric, cross-sectional, observational study, conducted on 114 patients with SARS-CoV-2. Clinical and laboratory parameters [renal function, serum electrolytes, inflammatory state, blood gas analysis, Interleukin 6 (IL-6) and urinalysis] were evaluated...
