Non-anionic gap metabolic acidosis

Guidelines on the use of dialysis treatment in patients with chronic kidney disease (CKD) and TPM (Topiramate) intoxication are controversial. A 51-year-old man with epilepsy and CKD was carried to our emergency department for dysuria and sickness. He chronically assumed TPM 100 mg 3/day. Creatinine level was 2.1 mg/dL, blood urea nitrogen 70 mg/dL, and inflammation indexes were increased. We started empirical antibiotic therapy and rehydration. The day two he had diarrhea and an acute insurgence of dizziness, confusion, and bicarbonate levels reduction...

Linezolid has been the mainstay of treatment for multidrug-resistant Gram-positive bacteria. Common adverse effects with linezolid include diarrhea, nausea, headache, and bone marrow suppression. A less common and understudied side effect is lactic acidosis. This study describes a 19-year-old man with linezolid-induced lactic acidosis (LILA). The patient was admitted for the management of acute decompensated systolic heart failure, which improved on guideline-directed medication therapy (GDMT). During hospitalization, he developed an erythematous weeping cellulitis infection of his right lower extremity and was started on linezolid 600 mg every 12 hours with wound and blood cultures collected...

Lactic acidosis is considered to be one of the most common causes of high anion gap metabolic acidosis in hospitalized patients. Warburg effect can present with type B lactic acidosis and is considered to be a rare but well-known complication of hematological malignancies. Here, we present the case of a 39-year-old male who had type B lactic acidosis and recurrent hypoglycemia secondary to newly diagnosed Burkitt lymphoma. This case highlights the importance of considering malignancy workup in any case of unexplained type B lactic acidosis with vague clinical presentation, which can aid in early diagnosis and management...

BACKGROUND: Nephrolithiasis as a feature of rheumatologic diseases is under recognized. Understanding presenting features, diagnostic testing is crucial to proper management. CASE PRESENTATION: A 32 year old woman with a history of recurrent complicated nephrolithiasis presented to a rheumatologist for a several month history of fatigue, dry eyes, dry mouth, arthralgias. She had a positive double-stranded DNA, positive SSA and SSB antibodies. She was diagnosed with Systemic Lupus erythematosus (SLE) and Sjogren's syndrome and was started on mycophenalate mofetil...

The association of renal tubular acidosis (RTA) and Sjögren's syndrome (SS) has been well-documented in the literature previously but is often undiagnosed in clinical practice. In this case report, we present a case of a woman with distal RTA who presented with nausea, vomiting, and confusion. The case shows the diagnostic value of urine studies when evaluating a patient who has exaggerated and unexplained electrolyte losses and how this will change management. Recognizing the extra glandular manifestations of patients with SS is important for patient care to prevent delays in care and treatment...

OBJECTIVES: This study assessed the ability of end-tidal carbon dioxide (ETCO2 ) in predicting in-hospital mortality and intensive care unit (ICU) admission compared to standard vital signs at ED triage as well as comparing to measures of metabolic acidosis. METHODS: This prospective study enrolled adult patients presenting to the ED of a tertiary care Level I trauma center over 30 months. Patients had standard vital signs measured along with exhaled ETCO2 at triage...

This case report describes the recurrence of diabetic ketoacidosis (DKA) leading to hypertriglyceridemia-induced pancreatitis. Hypertriglyceridemia is present in 2-5% of patients with diabetic ketoacidosis. Hypertriglyceridemiainduced pancreatitis occurs in up to 4% of patients with diabetic ketoacidosis and is a well-reported complication. This is the first case report to the author's knowledge, where the same patient had two separate episodes of acute pancreatitis that have been attributed to diabetic ketoacidosis and resultant severe hypertriglyceridemia, etiology determined to be medication non-compliance...

Hypokalemic periodic paralysis has a high risk of life-threatening dysrhythmias. Hyperchloremic acidosis with hypokalemia is a dangerous condition. There are several causes of hypokalemia, in addition to common diseases, such as hyperthyroidism, hyperaldosteronism, and Cushing's syndrome; the other rare diseases include renal tubular acidosis (RTA), Bartter's syndrome, and Gitelman's syndrome. We present an unusual case of hypokalemic periodic paralysis, which was caused by a medullary sponge kidney with distal RTA...

OBJECTIVE: The aim of this study was to identify arterial blood gas (ABG) abnormalities, with a focus on a high anion gap (AG) metabolic acidosis and evaluate outcomes in coronavirus disease 2019 (COVID-19) patients admitted to the ICU. METHODS: A retrospective, observational study was conducted in a tertiary hospital in Cape Town during the first and second COVID-19 waves. Age, gender, sodium (Na), potassium (K), chloride (Cl), bicarbonate (HCO3std), pH, partial pressure of carbon dioxide (pCO2), creatinine, estimated glomerular filtration rate (eGFR), lactate levels and ABG results were obtained...

OBJECTIVES: Neonatal-onset organic acidemias (OAs) account for 80% of neonatal intensive care unit (NICU) admissions due to inborn errors of metabolism. The aim of this study is to analyze clinical features and follow-up of neonates diagnosed with OAs in a metabolic referral center, focusing on perinatal characteristics and the impact of first the metabolic crisis on long-term outcome. METHODS: Perinatal features, clinical and laboratory characteristics on admission and follow-up of 108 neonates diagnosed with OAs were retrospectively analyzed...

INTRODUCTION: Patients with ethanol dependence may consume vanilla extract for the high alcohol content. CASE PRESENTATION: A 42-year-old male with ethanol dependence who developed status epilepticus, severe anion gap metabolic acidosis and a hyperosmolar non-ketotic coma after ingestion of 600 mL vanilla essence. He was found to have an osmolar gap of 151 with a marked pseudohypertriglyceridaemia of 96.4 mmol/L (8350 mg/dL), found to be secondary to significantly elevated glycerol levels...

Acid-base disorders are common in the intensive care unit. By utilizing a systematic approach to their diagnosis, it is easy to identify both simple and mixed disturbances. These disorders are divided into four major categories: metabolic acidosis, metabolic alkalosis, respiratory acidosis, and respiratory alkalosis. Metabolic acidosis is subdivided into anion gap and non-gap acidosis. Distinguishing between these is helpful in establishing the cause of the acidosis. Anion gap acidosis, caused by the accumulation of organic anions from sepsis, diabetes, alcohol use, and numerous drugs and toxins, is usually present on admission to the intensive care unit...

BACKGROUND: Alcoholic ketoacidosis (AKA) is a common reversible biochemical pathology arising from hyperketonaemia in patients with a history of chronic alcohol consumption. It is typically fatal when there is a delay in early recognition and management. A further complicating factor is that this condition is frequently confused with diabetic ketoacidosis (DKA). CASE PRESENTATION: This report presents the case study of an elderly Chinese man with a 40-year history of alcohol consumption...

To highlight the implications of the metabolic stress response and the role of anaesthesia in attenuating its deleterious effects, we present this extremely rare case of non-diabetic euglycaemic ketoacidosis with rapid weight loss in a post-traumatic surgical patient. Ketoacidosis is the accumulation of ketone bodies in blood and is generally associated with relative or absolute insulin deficiency secondary to diabetes mellitus, sodium-glucose cotransporter 2 inhibitors and extensive fasting. The stress of systemic disease, trauma or surgery in such predisposed patients could precipitate ketoacidosis...

INTRODUCTION: There are variable complications of hyperthyroidism, including atrial fibrillation, heart failure, osteoporosis, and thyroid storm. One infrequent complication of hyperthyroidism is non-diabetic ketoacidosis (NDKA). To the best of our knowledge, our case is the third report of NDKA related to thyrotoxicosis. PATIENT CONCERN: We describe a case of a 41-year-old African lady with no past medical history presented to our hospital with severe abdominal pain and vomiting for three weeks...

Background: Post-COVID-19 nephropathies have been reported profusely in the literature with diverse pathophysiological mechanisms. To the best of our knowledge, this is the first report of transient distal (type 1) renal tubular acidosis (dRTA) in an infant with confirmed COVID-19. Case Presentation . We describe a 32-day-old female with diarrhea and fever without respiratory complaints. Her weight, height, and head circumference were normal for age. The primary lab test showed leukocytosis, neutrophilia, elevated inflammatory markers, and non-anion-gap metabolic acidosis...

Co-existence of bats with a wide range of infectious agents relates to their co-evolutionary history and specific physiology. Here, we examined blood samples collected during hibernation and the post-hibernation period to assess the influence of trypanosomes and babesias on the health status of 50 Noctule bats ( Nyctalus noctula ) using nested PCR. The impact of blood parasites on health was assessed by analysis of haematology and blood chemistry parameters in 21 bats. Prevalence of trypanosomes ( Trypanosoma dionisii and T...

Ischemic colitis is one of the most common ischemic pathologies of the gastrointestinal system and can be divided into non-gangrenous and gangrenous forms. The pathophysiology involves restricted blood supply to the colonic mucosa. Several risk factors have been implicated in the development of ischemic colitis. Lactulose, one of the mainstay therapies for the treatment of hepatic encephalopathy in patients with cirrhosis, has been rarely reported as a cause of ischemic colitis. To the best of our knowledge, there has been only one case report associating lactulose use with the development of ischemic colitis...
