Metformin intoxication with lactic acidosis, a potentially lethal condition, may develop in diabetic patients when the drug dose is inappropriate and/or its clearance is reduced. Diagnosis and therapy may be delayed due to nonspecific symptoms at presentation, with severe anion gap metabolic acidosis and elevated serum creatinine values being the most prominent laboratory findings. Confirmation requires measurement of serum metformin by high-performance liquid chromatography-tandem mass spectrometry, but this technique is available only at specialized institutions and cannot be relied on as a guide to immediate treatment...

BACKGROUND: Gordon syndrome (GS) is a rare form of monogenic hypertension characterized by low renin hypertension, hyperkalemia, hyperchloremic metabolic acidosis, and normal glomerular filtration rate. To date, four genes causing GS have been identified as: WNK1, WNK4, CUL3, and KLHL3. CASE REPORT: We report three cases of GS in two families. All patients presented with typical clinical features of GS and had a known dominant KLHL3 mutation. Oral thiazide treatment with low salt diet resulted in normalization of blood pressure and serum electrolytes in all three cases...

In this review, we analyze the etiopathogenic principles of urinary lithiasis formation. In the kidney, calcifications that may cause renal lithiasis are produced as a consequence of processes that injury the urothelium at the papilla and Bellini's ducts. With the improvement of imaging techniques, mainly micro CT scan, it is possible to detect them and we may be able to anticipate to the formation of lithiasis. As we well know, there are different factors that influence the formation of the calculi depending on their composition...

Urinary lithiasis is a prevalent disorder of uncertain origin which provokes health problems through potential harm to the urinary system, renal parenchyma or the body as a whole, with a frequent trend to relapse. Historically urinary calculi have been studied and treated as an isolated disease but nowadays we know more about their connection with other pathological entities. In a small percentage of patients, diseases like primary hyperparathyroidism, tubular renal acidosis, inflammatory bowel disease or bariatric surgery have a fairly well studied physiopathological link with kidney stones...

OBJECTIVES: To report the long-term outcome of ileal ureteric replacement (IUR) in complex reconstruction of the urinary tract. PATIENTS AND METHODS: From 1991 to 2016, IUR was performed in 157 patients with structural or functional ureteric loss. In 52 patients, bilateral IUR became necessary. Implantation sites where either the native urinary bladder (n=79) or intestinal reservoirs (n=78). In the latter group, the technique was used at the time of primary urinary diversion (n=34), in a secondary approach (n=29) and in undiversion or conversion procedures (n=15)...

The infant (a girl aged 6 months) was admitted to the hospital because of oliguria and acute renal dysfunction. The laboratory examination results showed serious metabolic acidosis and increased blood urea nitrogen and serum creatinine levels. The patient continued to be anuric after 10 days of treatment with continuous renal replacement therapy (CRRT). she died a day later. The family history showed that the patient's sister died of acute renal failure 6 months after birth. The genomic sequencing results showed AGXT mutation in the patient and confirmed the diagnosis of primary hyperoxaluria type 1 (PH1)...

Use of 0.9% sodium chloride for total gut irrigation (TGI) through nasogastric route is an effective method of bowel preparation in children undergoing colorectal surgeries. TGI with normal saline (NS) can result in nausea, vomiting, abdominal distension, and mild electrolyte imbalance; however, hyperchloremic metabolic acidosis has not been documented. We report two cases of hyperchloremic metabolic acidosis in children posted for colorectal surgery following TGI with NS who were successfully managed.

BACKGROUND: Recent studies have shown that early antiretroviral therapy (ART) initiation results in significant HIV transmission reduction. This is the rationale behind the "test and treat" policy of the World Health Organization (WHO). Implementation of this policy will lead to an increased incidence of ART-related adverse effects, especially in sub-Saharan Africa (SSA). Is the region yet ready to cope with such a challenging issue? MAIN BODY: The introduction and widespread use of ART have drastically changed the natural history of HIV/AIDS, but exposure to ART leads to serious medication-related adverse effects mainly explained by mitochondrial toxicities, and the situation will get worse in the near future...

Mechanical ventilation is widely recommended for reptiles during anesthesia, and while it is well-known that their low ectothermic metabolism requires much lower ventilation than in mammals, very little is known about the influence of ventilation protocol on the recovery from anesthesia. Here, 15 ball pythons (Python regius) were induced and maintained with isoflurane for 60min at one of three ventilation protocols (30, 125, or 250mlmin(-1)kg(-1) body mass) while an arterial catheter was inserted, and ventilation was then continued on 100% oxygen at the specified rate until voluntary extubation...

BACKGROUND AND OBJECTIVES: Uncorrected metabolic acidosis leads to higher death risk in dialysis patients. We observed the relationship between metabolic acidosis status and mortality rate in patients on renal replacement therapy during a median follow up time of 60 months. METHODS: We studied 76 patients on an on-line hemodiafiltration. The dialysis adequacy was defined by Kt/V for urea. The Framingham risk score (FRS) points were used to determine the 10-year risk for coronary heart disease...

Oceanic uptake of CO2 from the atmosphere has significantly reduced surface seawater pH and altered the carbonate chemistry within, leading to global Ocean Acidification (OA). The blood clam, Tegillarca granosa, is an economically and ecologically significant marine bivalve that is widely distributed along the coastal and estuarine areas of Asia. To investigate the physiological responses to OA, blood clams were exposed to ambient and three reduced seawater pH levels (8.1, 7.8, 7.6 and 7.4) for 40 days, respectively...

Interstitial acidification is a hallmark of solid tumor tissues resulting from the combination of different factors, including cellular buffering systems, defective tissue perfusion and high rates of cellular metabolism. Besides contributing to tumor pathogenesis and promoting tumor progression, tumor acidosis constitutes an important intrinsic and extrinsic mechanism modulating therapy sensitivity and drug resistance. In fact, pharmacological properties of anticancer drugs can be affected not only by tissue structure and organization but also by the distribution of the interstitial tumor pH...

BACKGROUND: Distal renal tubular acidosis (dRTA) is characterized by hyperchloraemic metabolic acidosis, hypokalaemia, hypercalciuria and nephrocalcinosis. It is due to reduced urinary acidification by the α-intercalated cells in the collecting duct and can be caused by mutations in genes that encode subunits of the vacuolar H(+)-ATPase (ATP6V1B1, ATP6V0A4) or the anion exchanger 1 (SLC4A1). Treatment with alkali is the mainstay of therapy. METHODS: This study is an analysis of clinical data from a long-term follow-up of 24 children with dRTA in a single centre, including a genetic analysis...

Metformin-associated lactic acidosis (MALA) is a rare but life-threatening complication. We report a case of MALA in a man aged 71 years who was treated with continuous renal replacement therapy (CRRT). The patient was brought to the hospital for prolonged and gradual worsening gastrointestinal symptoms. Although he received intravenous treatment, he developed catecholamine-resistant shock, and blood gas analysis revealed lactic acidosis. Bicarbonate and antibiotics for possible sepsis were initiated, but with no clear benefit...

This paper details the case of a 26-year-old woman with depletion syndrome and the effectiveness of her treatment with indomethacin. Villous adenomas are benign neoplasms with a high incidence of becoming malignant. A small percentage of villous adenomas are known to cause depletion syndrome, also referred to as the McKittrick-Wheelock syndrome, a condition characterised by secretory diarrhoea, dehydration, hyponatremia, hypokalaemia, hypochloraemia, metabolic acidosis and acute renal failure. Prostaglandin-E2 mediates the hypersecretion mechanism observed in depletion syndrome, and can be inhibited by cyclo-oxygenase inhibitors...
