Jason An, Branko Braam
Rationale: We hope to increase awareness that hypokalemic paralysis may be the first presentation of Sjögren syndrome, for which potassium-sparing diuretics can be an effective adjunct to potassium replenishment. Presenting concerns: A 73-year-old female presented to a peripheral hospital with quadriparesis and a critically low serum potassium of 1.6 mmol/L with U waves on the electrocardiogram (ECG). The initial arterial blood gas showed a pH of 7.19, bicarbonate of 13 mEq/L, and a CO2 of 35 mm Hg...

The recently published PRESERVE trial is presently the largest and most comprehensive clinical trial comparing commonly applied strategies for prevention of iodinated contrast-induced acute kidney injury in high-risk patients. The fundamental conclusion of the PRESERVE trial is that oral acetylcysteine and intravenous sodium bicarbonate are not superior to simple intravenous hydration with isotonic saline for the prevention of contrast-induced renal sequelae. In this commentary, we discuss the results in the context of selected past major trials, and provide insights into the strengths and potential weaknesses of the PRESERVE trial...

A 61-year-old woman was admitted to our hospital because of muscle paralysis and was found to have severe hypokalemia. A gallium-67 scintigram revealed a positive accumulation in the bilateral salivary glands, and a labial minor salivary gland biopsy demonstrated a massive lymphocyte infiltrate around the salivary ducts. She was diagnosed with Sjögren's syndrome (SS) associated with renal tubular acidosis. Renal biopsy revealed tubulointerstitial nephritis with a mild focal infiltration of lymphocytes and plasma cells...

Two cases of children diagnosed with renal tubular acidosis (RTA) associated with autoimmune hypothyroidism are presented. Case 1 developed an intestinal ileus at the age of five in the context of a respiratory problem. The tests performed confirmed metabolic acidosis, hyperchloraemia, hypokalaemia and nephrocalcinosis. Case 2 was diagnosed with hypothyroidism at the age of 11, and with RTA two years later. In both patients, the diagnosis of RTA was verified when decreased maximum urinary pCO2 was found. In case 2, a proximal bicarbonate leak (type 3 RTA) was also confirmed...

Ochratoxin A (OTA) is a mycotoxin considered the most powerful renal carcinogen in rodents and classified as a possible human carcinogen. Though its mechanism of action is still unknown, indirect DNA reactivity mediated by oxidative stress has been hypothesized to play an important role. Moreover, large sex-differences have been observed in carcinogenicity studies, male rats being more sensitive than females. Male and female F344 rats were administered (p.o.) with bicarbonate or 0.5 mg OTA/kg b.w. for 7 days; or with bicarbonate, 0...

Sodium bicarbonate (NaHCO3 ) slows the decline in kidney function in patients with chronic kidney disease (CKD), yet the mechanisms mediating this effect remain unclear. The Dahl salt-sensitive (SS) rat develops hypertension and progressive renal injury when fed a high salt diet; however, the effect of alkali loading on kidney injury has never been investigated in this model. We hypothesized that 'NaHCO3 protects from the development of renal injury in Dahl salt-sensitive rats via luminal alkalization which limits the formation of tubular casts, which are a prominent pathological feature in this model...

REVIEW
Megan A Van Berkel, Jessica L Elefritz
PURPOSE: Current off-label uses of acetazolamide in hospitalized patients are reviewed. SUMMARY: Acetazolamide is a carbonic anhydrase inhibitor typically used for indications including epilepsy, glaucoma, edema, and altitude sickness but it may be prescribed in hospitalized patients for off-label indications. It inhibits carbonic anhydrase, which leads to reduced hydrogen ion secretion in the proximal renal tubule, resulting in increased bicarbonate and cation excretion and causing urinary alkalization and diuresis...

Expression of the glutamine transporter SNAT3 increases in kidney during metabolic acidosis, suggesting a role during ammoniagenesis. Microarray analysis of Nrf2 knock-out (KO) mouse kidney identified Snat3 as the most significantly down-regulated transcript compared to wild-type (WT). We hypothesized that in the absence of NRF2 the kidney would be unable to induce SNAT3 under conditions of metabolic acidosis and therefore reduce the availability of glutamine for ammoniagenesis. Metabolic acidosis was induced for 7 days in WT and Nrf2 KO mice...

Calciphylaxis presents with painful purpura and intractable skin ulcers on the trunk and particularly the distal extremities, and it mainly occurs in patients on chronic dialysis. A 66-year-old man with renal failure due to diabetic nephropathy was on peritoneal dialysis alone for 1 year, followed by peritoneal dialysis combined with hemodialysis for 3 years. He developed calciphylaxis of the penis, which was diagnosed from the skin biopsy findings and clinical observation. To treat this condition, PD was stopped and HD was performed three times a week...

Chronic kidney disease (CKD) is a very common disorder in elderly cats. A proper renal diet represents the most efficient therapeutic intervention to improve survival and life quality in feline patients with 3 and 4 International Renal Interest Society (IRIS) stages. Twenty cats were selected in this study. Ten were administered the dietary supplementation for 360 days and the other ten, whose owners did not give consent for any supplemental therapies apart from the renal diet, were selected from a clinical database and used as control group...

Prolonged effects of dietary acid intake on acid-base status and kidney function have not yet been studied in an intervention study in healthy subjects. Dietary acid load can be estimated by calculating the potential renal acid load (PRAL) of foods. Effects of low-PRAL and moderate-PRAL diets on acid-base status and kidney function were investigated during a 12-week exercise training period. Healthy, 20-50-year-old men ( n = 21) and women ( n = 25) participated in the study and were randomly divided into low-PRAL and moderate-PRAL groups...

Acute lymphoblastic leukemia (ALL) presenting as Fanconi syndrome (FS) is extremely rare. Here, we report a case of ALL presenting as bilateral nephromegaly following FS. A 2-year-old girl was unexpectedly diagnosed with bilateral nephromegaly. After 2 weeks, she developed general fatigue, thirst, and polyuria. Laboratory examinations revealed renal tubular acidosis, hypokalemia, hypophosphatemia, and aminoaciduria, and FS was diagnosed. Replacement of bicarbonate and potassium did not improve her condition...

REVIEW
Miriam Zacchia, Giovanna Capolongo, Luca Rinaldi, Giovambattista Capasso
The thick ascending limb (TAL) of Henle's loop is a crucial segment for many tasks of the nephron. Indeed, the TAL is not only a mainstay for reabsorption of sodium (Na+ ), potassium (K+ ), and divalent cations such as calcium (Ca2+ ) and magnesium (Mg2+ ) from the luminal fluid, but also has an important role in urine concentration, overall acid-base homeostasis, and ammonia cycle. Transcellular Na+ transport along the TAL is a prerequisite for Na+ , K+ , Ca2+ , Mg2+ homeostasis, and water reabsorption, the latter through its contribution in the generation of the cortico-medullar osmotic gradient...
