Liddle's-like syndrome associated with nephrotic syndrome secondary to membranous nephropathy: the first case report.

BMC Nephrol 2018 May 23;19(1):122. Epub 2018 May 23.

Department of Nephrology and Rheumatology, Iwate Prefectural Central Hospital, 1-4-1, Morioka, 020-0066, Japan.

Background: Liddle's syndrome is a rare monogenic form of hypertension caused by truncating or missense mutations in the C termini of the epithelial sodium channel (ENaC) β or γ subunits. Patients with this syndrome present with early onset of hypertension, hypokalemia, metabolic alkalosis, hyporeninemia and hypoaldosteronism, and a potassium-sparing diuretics (triamterene or amiloride) can drastically improves the disease condition. Although elderly patients having these characteristics were considered to have Liddle's syndrome or Liddle's-like syndrome, no previous report has indicated that Liddle's-like syndrome could be caused by nephrotic syndrome of primary glomerular disease, which is characterized by urinary excretion of > 3 g of protein/day plus edema and hypoalbuminemia, or has explained how the activity function of ENaC could be affected in the setting of high proteinuria.

Diabetes mellitus and hyperkalemic renal tubular acidosis: case reports and literature review.

J Bras Nefrol 2017 Oct-Dec;39(4):481-485

Hospital de Egas Moniz, Centro Hospitalar de Lisboa Ocidental, Lisboa, Portugal.

Hyporeninemic hypoaldosteronism, despite being common, remains an underdiagnosed entity that is more prevalent in patients with diabetes mellitus. It presents with asymptomatic hyperkalemia along with hyperchloraemic metabolic acidosis without significant renal function impairment. The underlying pathophysiological mechanism is not fully understood, but it is postulated that either aldosterone deficiency (hyporeninemic hypoaldosteronism) and/or target organ aldosterone resistance (pseudohypoaldosteronism) may be responsible.

Clinical perspectives in congenital adrenal hyperplasia due to 11β-hydroxylase deficiency.

Endocrine 2017 Jan 7;55(1):19-36. Epub 2016 Dec 7.

Department of Endocrinology, Royal Darwin Hospital, Darwin, NT, Australia.

Congenital adrenal hyperplasia due to 11 beta-hydroxylase deficiency is a rare autosomal recessive genetic disorder. It is caused by reduced or absent activity of 11β-hydroxylase (CYP11B1) enzyme and the resultant defects in adrenal steroidogenesis. The most common clinical features of 11 beta-hydroxylase deficiency are ambiguous genitalia, accelerated skeletal maturation and resultant short stature, peripheral precocious puberty and hyporeninemic hypokalemic hypertension.

Hyporeninemic hypoaldosteronism and diabetes mellitus: Pathophysiology assumptions, clinical aspects and implications for management.

World J Diabetes 2016 Mar;7(5):101-11

André Gustavo P Sousa, Adriana Bezerra Nunes, Department of Clinical Medicine, Federal University of Rio Grande do Norte, Natal, RN 59012-300, Brazil.

Patients with diabetes mellitus (DM) frequently develop electrolyte disorders, including hyperkalemia. The most important causal factor of chronic hyperkalemia in patients with diabetes is the syndrome of hyporeninemic hypoaldosteronism (HH), but other conditions may also contribute. Moreover, as hyperkalemia is related to the blockage of the renin-angiotensin-aldosterone system (RAAS) and HH is most common among patients with mild to moderate renal insufficiency due to diabetic nephropathy (DN), the proper evaluation and management of these patients is quite complex.

Apparent mineralocorticoid excess and the long term treatment of genetic hypertension.

J Steroid Biochem Mol Biol 2017 01 15;165(Pt A):145-150. Epub 2016 Feb 15.

Adrenal Steroid Disorder Group, Department of Pediatrics, Icahn School of Medicine at Mount Sinai, New York, NY, United States.

Apparent mineralocorticoid excess (AME) is a genetic disorder causing severe hypertension, hypokalemia, and hyporeninemic hypoaldosteronism owing to deficient 11 beta-hydroxysteroid dehydrogenase type-2 (11βHSD2) enzyme activity. The 11βHSD2 enzyme confers mineralocorticoid receptor specificity for aldosterone by converting cortisol to its inactive metabolite, cortisone and inactivating the cortisol-mineralocorticoid receptor complex. The 20year follow-up of a consanguineous Iranian family with three sibs affected with AME shows the successes and pitfalls of medical therapy with spironolactone. Read More

[Drug-induced exacerbation of hypoaldosteronism in autoimmune polyglandular syndrome type 2].

Wiad Lek 2012 ;65(4):239-42

Klinika Chorób Wewnetrznych i Farmakologii Klinicznej, Katedra Farmakologii, Slaski Uniwersytet Medyczny w Katowicach.

Hypoaldosteronism is a clinical condition resulting from inadequate stimulation of aIdosterone secretion (hyporeninemic hypoaIdosteronism), defects in adrenal synthesis of aldosterone (hyperreninemic hypoaldosteronism), or resistance to the peripheral action of this hormone (pseudohypoaldosteronism). The disease is characterized by a wide spectrum of clinical manifestations, ranging from asymptomatic hyperkalemia to life-threatening volume depletion, and, if unrecognized and untreated, it increases morbidity and mortality rates. In this paper, we report a case of a woman diagnosed with autoimmune polyglandular syndrome type 2. Read More

Targeted mutation of SLC4A5 induces arterial hypertension and renal metabolic acidosis.

Hum Mol Genet 2012 Mar 14;21(5):1025-36. Epub 2011 Nov 14.

Department of Cardiac Development and Remodelling, Max Planck Institute for Heart and Lung Research, Ludwigstrasse 43, D-61231 Bad Nauheim, Germany.

The human SLC4A5 gene has been identified as a hypertension susceptibility gene based on the association of single nucleotide polymorphisms with blood pressure (BP) levels and hypertension status. The biochemical basis of this association is unknown particularly since no single gene variant was linked to hypertension in humans. SLC4A5 (NBCe2, NBC4) is expressed in the collecting duct of the kidney and acts as an electrogenic ion-transporter that transports sodium and bicarbonate with a 1:2 or 1:3 stoichiometry allowing bicarbonate reabsorption with relatively minor concurrent sodium uptake.

Hyperkalemia.

Am Fam Physician 2006 Jan;73(2):283-90

Department of Family Medicine, Oregon Health & Science University, Portland, Oregon, USA.

Hyperkalemia is a potentially life-threatening metabolic problem caused by inability of the kidneys to excrete potassium, impairment of the mechanisms that move potassium from the circulation into the cells, or a combination of these factors. Acute episodes of hyperkalemia commonly are triggered by the introduction of a medication affecting potassium homeostasis; illness or dehydration also can be triggers. In patients with diabetic nephropathy, hyperkalemia may be caused by the syndrome of hyporeninemic hypoaldosteronism. Read More

Effects of preproglucagon-derived peptides and exendins on steroid-hormone secretion from dispersed adrenocortical cells of normal and streptozotocin-induced diabetic rats.

Int J Mol Med 2003 Jul;12(1):115-9

Department of Histology and Embryology, Karol Marcinkowski University of Medical Sciences, PL-60781 Poznan, Poland.

Many lines of evidence have shown that preproglucagon-derived peptides affect steroid secretion from dispersed adrenocortical cells, and that streptozotocin (STZ)-induced experimental diabetes alters adrenocortical-cell function. Hence, we compared the effects of glucagon, glucagon-like peptide (GLP)-1 and GLP-2 on basal and ACTH-stimulated secretion of dispersed adrenocortical cells from normal and STZ-induced diabetic rats. We also examined the effects of exendins (EX) 3 and 4, because EX4 is known to be a potent and long-lasting agonist of GLP-1 receptors. Read More

J Clin Endocrinol Metab 1998 Jul;83(7):2244-54

Department of Pediatrics, New York Hospital-Cornell Medical Center, New York 10021, USA.

Apparent mineralocorticoid excess (AME) is a genetic disorder causing pre- and postnatal growth failure, juvenile hypertension, hypokalemic metabolic alkalosis, and hyporeninemic hypoaldosteronism due to a deficiency of 11 beta-hydroxysteroid dehydrogenase type 2 enzyme activity (11 beta HSD2). The 11 beta HSD2 enzyme is responsible for the conversion of cortisol to the inactive metabolite cortisone and therefore protects the mineralocorticoid receptors from cortisol intoxication. Several homozygous mutations are associated with this potentially fatal disease. Read More
