Introduction: The routine and gold standard method to diagnose of acid - base disturbance is arterial blood gas (ABG) sampling. Capnography could be used to measure the end-tidal carbon dioxide (ETCO2) levels and ETco2 has a close correlation with the PaCo2. The aim of this study was comparison the ETco2 and arterial blood bicarbonate levels in patients with metabolic acidosis. Methods: In a descriptive-analytical study that performed in Emergency Department of Emam Reza Medical Research and Training Hospital of Tabriz on patients with metabolic acidosis, ETco2 level and blood bicarbonate levels in 262 patients were evaluated...

Dichloroacetate (DCA) has several therapeutic applications based on its pharmacological property of inhibiting pyruvate dehydrogenase kinase. DCA has been used to treat inherited mitochondrial disorders that result in lactic acidosis, as well as pulmonary hypertension and several different solid tumors, the latter through its ability to reverse the Warburg effect in cancer cells and restore aerobic glycolysis. The main clinically limiting toxicity is reversible peripheral neuropathy. Although administration of high doses to rodents can result in liver cancer, there is no evidence that DCA is a human carcinogen...

BACKGROUND: Correction of metabolic acidosis (MA) with nutritional therapy or bicarbonate administration is widely used in chronic kidney disease (CKD) patients. However, it is unknown whether these interventions reduce insulin resistance (IR) in diabetic patients with CKD. We sought to evaluate the effect of MA correction on endogenous insulin action in diabetic type 2 (DM2) CKD patients. METHODS: A total of 145 CKD subjects (83 men e 62 women) with DM2 treated with oral antidiabetic drugs were included in the study and followed up to 1 year...

BACKGROUND: Children with chronic kidney disease are frequently born small for gestational age (SGA) and prone to disproportionately short stature. It is unclear how SGA affects growth after kidney transplantation (KTx). METHODS: Linear growth (height, sitting height, and leg length) was prospectively investigated in a cohort of 322 pediatric KTx recipients, with a mean follow-up of 4.9 years. Sitting height index (ratio of sitting height to total body height) was used to assess body proportions...

There are published reports stating that some of the congenital metabolic diseases, such as lysinuric protein intolerance, multiple sulphatase deficiency, galactosemia, Gaucher disease, Pearson syndrome, and galactosialidosis, might lead to secondary hemophagocytic lymphohistiocytosis (HLH). However, to date, to our knowledge, the long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency has never been investigated among patients with HLH. Here, we report on a patient who was referred to our institution for a differential diagnosis of pancytopenia, liver failure, and rhabdomyolysis...

Celiac crisis, an atypical presentation of celiac disease, is characterized by acute diarrhea and severe metabolic derangements. This diagnosis is often missed in the differential of acute diarrheal illness. Our patient is a 69-year-old man who presented with ICD firing and was found to have profound metabolic derangements. Further evaluation revealed undiagnosed celiac disease and his symptoms resolved with a gluten-free diet. Celiac crisis should be considered in all patients presenting with acute diarrhea, metabolic acidosis, and severe electrolyte abnormalities as management can be life-saving...

In the management of patients with chronic kidney diseases (CKD), a low-protein diet usually refers to a diet with protein intake of 0.6 to 0.8 grams per kilogram of body weight per day (g/kg/day) and should include at least 50% high-biologic-value protein. It may be supplemented with essential acids or nitrogen- free ketoanalogues if <0.6 g/kg/d. Low-protein diet can reduce proteinuria especially in non-diabetic CKD patients. In hypoalbuminemic patients it may lead to an increase in serum albumin level...

In sickle cell trait (SCT), hemoglobin A (HbA) and S (HbS) are co-expressed in each red blood cell (RBC). While homozygous expression of HbS (HbSS) leads to polymerization and sickling of RBCs resulting in sickle cell disease (SCD) characterized by hemolytic anemia, painful vaso-occlusive episodes and shortened life-span, SCT is considered a benign condition usually with minor or no complications related to sickling. However, physical activities that cause increased tissue oxygen demand, dehydration and/or metabolic acidosis leads to increased HbS polymerization and life-threatening complications including death...

BACKGROUND Besides providing anesthesia for surgery, the anesthesiologist's role is to optimize the patient for surgery and for post-surgical recovery. This involves timely identification and treatment of medical comorbidities and abnormal laboratory values that could complicate the patient's perioperative course. There are several potential causes of anion and non-anion gap metabolic acidosis in surgical patients, most of which could profoundly affect a patient's surgical outcome. Thus, the presence of an acute acid-base disturbance requires a thorough workup, the results of which will influence the patient's anesthetic management...

Nitazoxanide (NTZ) is a broad-spectrum anti-parasitic drug used against a wide variety of protozoans and helminthes. Albendazole, its active metabolite albendazole sulfoxide (ABZSO), is one of the drugs of choice to treat both intestinal and tissue helminth and protozoan infections. However little is known regarding their impact on the metabolism of parasites. The aim of this study was to compare the in vitro effect of NTZ and ABZSO in the glycolysis of Taenia crassiceps cysticerci. The cysticerci were treated with 1...

Medium- and short-chain acyl-CoA dehydrogenase deficiency is a disorder of fatty acid β-oxidation. Gene mutation prevents medium- and short-chain fatty acids from entry into mitochondria for oxidation, which leads to multiple organ dysfunction. In this study, serum acylcarnitines and the organic acid profile in urea were analyzed in two children whose clinical symptoms were hypoglycemia and metabolic acidosis. Moreover, gene mutations in the two children and their parents were evaluated. One of the patients was a 3-day-old male who was admitted to the hospital due to neonatal asphyxia, sucking weakness, and sleepiness...

The regulation of the acid-base balance and pH is critical for the organism. The most important buffer system is CO2 / HCO3(-). The kidney controls systemic bicarbonate and therefore the metabolic regulation and the lung is relevant for respiratory regulation by an effective CO2 elimination. There are four acid-base disorders with two metabolic and two respiratory disorders (acidosis and alkalosis). The anion gap enables a further workup of metabolic acidosis.

A large proportion of empirical research and reviews investigating the ergogenic potential of sodium bicarbonate (NaHCO3) supplementation have focused predominately on performance outcomes and only speculate about underlying mechanisms responsible for any benefit. The aim of this review was to critically evaluate the influence of NaHCO3 supplementation on mechanisms associated with skeletal muscle fatigue as it translates directly to exercise performance. Mechanistic links between skeletal muscle fatigue, proton accumulation (or metabolic acidosis) and NaHCO3 supplementation have been identified to provide a more targeted, evidence-based approach to direct future research, as well as provide practitioners with a contemporary perspective on the potential applications and limitations of this supplement...

D-lactic acidosis is a rare complication that occurs mainly in patients with malabsorption due to a surgically altered gastrointestinal tract anatomy, namely in short bowel syndrome or after bariatric surgery. It is characterized by rapid development of neurological symptoms and severe metabolic acidosis, often with a high serum anion gap. Malabsorbed carbohydrates can be fermented by colonic microbiota capable of producing D-lactic acid. Routine clinical assessment of serum lactate covers only L-lactic acid; when clinical suspicion for D-lactic acidosis is high, special assays for D-lactic acid are called for...
