BACKGROUND: Liddle syndrome is an autosomal dominant form of monogenic hypertension. Phenotypic variability makes it difficult to identify patients with Liddle syndrome, resulting in misdiagnosis and severe complications at early age. OBJECTIVES: To identify mutation in SCNN1B and SCNN1G genes in an adolescent with suspicious Liddle syndrome and his family members and to explore the screening target subjects of Liddle syndrome. METHODS: Genetic analysis of the C-terminus of SCNN1B and SCNN1G genes was conducted in an adolescent, with treatment-resistant hypertension and hypokalemia, who was suspected of having Liddle syndrome, and his family members...

OBJECTIVE: Disturbances in potassium (K) levels are relatively common and may be associated with significant morbidity and mortality; however, treatments vary. Our purpose was to determine the incidence, treatments, and outcomes associated with hyperkalemia and hypokalemia in emergency department (ED) patients. METHODS: We performed a structured, retrospective review of electronic medical records of consecutive adult ED patients with K measured while in the ED. Demographic, clinical, and laboratory data as well as treatments, disposition, and in-hospital complications were collected...

REVIEW
Anwar Dayan Osborne
Accelerated therapeutic protocols targeting metabolic conditions are ideal for observation unit care. Because many conditions, such as hypokalemia and hyperglycemia, have little to no diagnostic uncertainty, the care in the unit is often straightforward. Additionally, some components of care for the endocrine condition may exhaust services, such as phlebotomy. Hence, this discussion focuses resource utilization and management considerations for the purposes of matching the level of care to the severity of the conditions...

OBJECTIVE: The current study aimed to evaluate the role of Küpers' score in predicting unilateral aldosteronism, and develop a modified score in Chinese patients with primary aldosteronism. METHODS: The current retrospective study included 406 patients with primary aldosteronism who underwent successful adrenal venous sampling (AVS) and were divided into the unilateral (n = 211) and bilateral (n = 195) groups according to the AVS results. Normokalemia was noted in both the unilateral (n = 64) and bilateral groups (n = 84) when plasma and urinary aldosterone were measured...

Xiaoyan Peng, Lanping Jiang, Chen Chen, Yan Qin, Tao Yuan, Ou Wang, Xiaoping Xing, Xuemei Li, Min Nie, Limeng Chen
BACKGROUND: Gitelman syndrome (GS), an inherited autosomal recessive salt-losing renal tubulopathy caused by mutations in SLC12A3 gene, has been associated with normal prostaglandin E2 (PGE2) levels since 1995 by a study involving 11 clinically diagnosed patients. However, it is difficult to explain why cyclooxygenase-2 (COX2) inhibitors, which pharmacologically reduce PGE2 synthesis, are helpful to patients with GS, and few studies performed in the last 20 years have measured PGE2 levels...

Primary aldosteronism (PA) is the most common form of secondary hypertension (HTN), with an estimated prevalence of 4% of hypertensive patients in primary care and around 10% of referred patients. Patients with PA have higher cardiovascular morbidity and mortality than age- and sex-matched patients with essential HTN and the same degree of blood pressure elevation. PA is characterized by an autonomous aldosterone production causing sodium retention, plasma renin supression, HTN, cardiovascular damage, and increased potassium excretion, leading to variable degrees of hypokalemia...

We present the case of a 58-year-old woman who developed hypokalaemia and metabolic alkalosis 2 weeks after therapy with colistimethate sodium for the treatment of chronic lower limb ulcer infection by extensively drug-resistant (XDR) Pseudomonas aeruginosa. The metabolic changes observed resembled Bartter syndrome, a group of congenital disorders affecting the distal segments of the renal tubules. The metabolic abnormalities reversed spontaneously 6 days after drug discontinuation. Acquired forms of Bartter syndrome have been reported during courses of antibiotic therapy; however, to our knowledge, this is the first documented case associated with colistimethate therapy in an adult...

The study reports a female neonate with a gestational age of 29(+2) weeks and a birth weight of 1 210 g. Ten minutes after birth, the neonate was admitted to the hospital due to shortness of breath. Several days after birth, the neonate presented with hyperglycemia, polyuria, and poor weight gain, accompanied by azotemia, hypochloremic metabolic alkalosis, hypokalemia, and hyponatremia. Laboratory examinations showed elevated levels of aldosterone, renin, and angiotensin II. Gene detection revealed SLC12A1 gene mutation...

BACKGROUND: Retrospective case series suggest that abnormalities in fluid, electrolyte, and acid-base homeostasis may occur among infants with a febrile urinary tract infection. Potentially inaccurate laboratory methods of sodium testing have often been used. METHODS: Between January 2009 and June 2016, we managed 80 previously healthy infants (52 males and 28 females) ≥4 weeks to ≤24 months of age with their first episode of acute pyelonephritis. Ionized sodium, ionized potassium and ionized chloride were determined by direct potentiometry, as recommended by the International Federation of Clinical Chemistry...

Background: The prolonged use of injectable agents in an MDR-TB regimen is recommended by the WHO despite association with ototoxicity and nephrotoxicity.Objective: We undertook this study to look at the relative adverse effects of capreomycin and amikacin.Methods: We reviewed the case notes of 100 consecutive patients treated at 4 MDR-TB treatment centres in the UK.Results: The median total duration of treatment with an injectable agent was 178 (IQR 109-192, n=73) days for those with MDR-TB, 179 (104-192, n=12) days for those with MDR-TB plus fluoroquinolone resistance and 558 (324-735, n=8) days for those with XDR-TB...

This 52-week, randomized, open-label study evaluated long-term safety/tolerability of fixed-dose combination azilsartan medoxomil/chlorthalidone (AZL-M/CLD) vs fixed-dose combination olmesartan medoxomil/hydrochlorothiazide (OLM/HCTZ) in patients with essential hypertension (stage 2; clinic systolic blood pressure 160-190 mm Hg). Initial AZL-M/CLD 40/12.5 mg/d (n=418) or OLM/HCTZ 20/12.5 mg/d (n=419) could be uptitrated during weeks 4 to 52 (AZL-M/CLD to 80/25 mg; OLM/HCTZ to 40/25 mg [United States] or 20/25 mg [Europe]) to meet blood pressure targets...

Ectopic ACTH/CRH co-secreting tumors are a very rare cause of Cushing's syndrome and only a few cases have been reported in the literature. Differentiating between Cushing's disease and ectopic Cushing's syndrome may be particularly difficult if predominant ectopic CRH secretion leads to pituitary corticotroph hyperplasia that may mimic Cushing's disease during dynamic testing with both dexamethasone and CRH as well as bilateral inferior petrosal sinus sampling (BIPSS). We present the case of a 24-year-old man diagnosed with ACTH-dependent Cushing's syndrome caused by an ACTH/CRH co-secreting midgut NET...

PURPOSE OF REVIEW: The physiologic determinants of each of the components of the basic metabolic profile in patients with heart failure will be explored. Additionally, the review will discuss the prognostic value of alterations in the basic metabolic profile as well as their effects on management. RECENT FINDINGS: Abnormalities in the basic metabolic profile have significant correlation with clinical outcomes and can modify treatment in heart failure. Hypochloremia has recently received increased attention for these reasons...

OBJECTIVE: To evaluate whether adverse event reports to the US Food and Drug Administration on incidents of ketoacidosis from use of sodium glucose cotransport inhibitors (SGLT2 inhibitors) provide insight into ways this new class of drugs is being prescribed with other antihyperglycemic agents; to examine possible mechanisms to explain ketoacidosis. DESIGN AND METHODS: Reports of adverse events concerned to SGLT2 inhibitors, namely, empagliflozin, dapagliflozin, and canagliflozin were obtained under the Freedom of Information Act for 5 years ending in August 31, 2015...

OBJECTIVES: Severe acute exacerbation (SAE) of chronic hepatitis B (CHB) may progress to liver failure with high potential mortality despite the prompt treatment with nucleos(t)ide analogs. This study aimed to evaluate the efficacy and safety of glycyrrhizin in the treatment of CHB with SAE. METHODS: Sixty patients with SAE of CHB were randomly treated with tenofovir plus intravenous glycyrrhizin (group A, n=30) or with tenofovir alone (group B, n=30). Primary end points were the improvement of serum levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) and model for end-stage liver disease (MELD) score...
