Hyponatremia and Hypernatremia MICHAEL M
This is a corrected version of the article that appeared in print. Diagnosis and Management of Sodium Disorders: Hyponatremia and Hypernatremia MICHAEL M. BRAUN, DO, Madigan Army Medical Center, Tacoma, Washington CRAIG H. BARSTOW, MD, Womack Army Medical Center, Fort Bragg, North Carolina NATASHA J. PYZOCHA, DO, Madigan Army Medical Center, Tacoma, Washington Hyponatremia and hypernatremia are common findings in the inpatient and outpatient settings. Sodium disorders are associated with an increased risk of morbidity and mortality. Plasma osmolality plays a critical role in the patho- physiology and treatment of sodium disorders. Hyponatremia and hypernatremia are classified based on volume status (hypovolemia, euvolemia, and hypervolemia). Sodium disorders are diagnosed by findings from the history, physical examination, laboratory studies, and evaluation of volume status. Treatment is based on symptoms and underlying causes. In general, hyponatremia is treated with fluid restriction (in the setting of euvolemia), isotonic saline (in hypovolemia), and diuresis (in hypervolemia). A combination of these therapies may be needed based on the presentation. Hypertonic saline is used to treat severe symptomatic hyponatremia. Medications such as vaptans may have a role in the treatment of euvolemic and hypervolemic hyponatremia. The treatment of hypernatremia involves correcting the underlying cause and correcting the free water deficit. Am( Fam Physician. 2015;91(5):299-307.

DDAVP Nasal Spray Is Provided As an Aqueous Solution for Intranasal Use
DDAVP® Nasal Spray (desmopressin acetate) Rx only DESCRIPTION DDAVP® Nasal Spray (desmopressin acetate) is a synthetic analogue of the natural pituitary hormone 8-arginine vasopressin (ADH), an antidiuretic hormone affecting renal water conservation. It is chemically defined as follows: Mol. wt. 1183.34 Empirical formula: C46H64N14O12S2•C2H4O2•3H2O 1-(3-mercaptopropionic acid)-8-D-arginine vasopressin monoacetate (salt) trihydrate. DDAVP Nasal Spray is provided as an aqueous solution for intranasal use. Each mL contains: Desmopressin acetate 0.1 mg Sodium Chloride 7.5 mg Citric acid monohydrate 1.7 mg Disodium phosphate dihydrate 3.0 mg Benzalkonium chloride solution (50%) 0.2 mg The DDAVP Nasal Spray compression pump delivers 0.1 mL (10 mcg) of DDAVP (desmopressin acetate) per spray. CLINICAL PHARMACOLOGY DDAVP contains as active substance desmopressin acetate, a synthetic analogue of the natural hormone arginine vasopressin. One mL (0.1 mg) of intranasal DDAVP has an antidiuretic activity of about 400 IU; 10 mcg of desmopressin acetate is equivalent to 40 IU. 1. The biphasic half-lives for intranasal DDAVP were 7.8 and 75.5 minutes for the fast and slow phases, compared with 2.5 and 14.5 minutes for lysine vasopressin, another form of the hormone used in this condition. As a result, intranasal DDAVP provides a prompt onset of antidiuretic action with a long duration after each administration. 1 2. The change in structure of arginine vasopressin to DDAVP has resulted in a decreased vasopressor action and decreased actions on visceral smooth muscle relative to the enhanced antidiuretic activity, so that clinically effective antidiuretic doses are usually below threshold levels for effects on vascular or visceral smooth muscle. -
Versus High-Chloride-Containing Hypertonic Solution for the Treatment

Journal of Intensive Care (2020) 8:32 https://doi.org/10.1186/s40560-020-00449-0 RESEARCH Open Access Low-chloride- versus high-chloride- containing hypertonic solution for the treatment of subarachnoid hemorrhage– related complications: The ACETatE (A low ChloriE hyperTonic solution for brain Edema) randomized trial Ofer Sadan1*, Kai Singbartl2, Jacqueline Kraft1, Joao McONeil Plancher1, Alexander C. M. Greven3, Prem Kandiah1, Cederic Pimentel1, C. L. Hall1, Alexander Papangelou4, William H. Asbury5, John J. Hanfelt6 and Owen Samuels1 Abstract Background: Recent reports have demonstrated that among patients with subarachnoid hemorrhage (SAH) treated with hypertonic NaCl, resultant hyperchloremia has been associated with the development of acute kidney injury (AKI). We report a trial comparing the effect of two hypertonic solutions with different chloride contents on the resultant serum chloride concentrations in SAH patients, with a primary outcome aimed at limiting chloride elevation. Methods: A low ChloridE hyperTonic solution for brain Edema (ACETatE) trial is a single-center, double-blinded, double-dummy, randomized pilot trial comparing bolus infusions of 23.4% NaCl and 16.4% NaCl/Na-acetate for the treatment of cerebral edema in patients with SAH. Randomization occurred when patients developed hyperchloremia (serum Cl− ≥ 109 mmol/L) and required hyperosmolar treatment. Results: We enrolled 59 patients, of which 32 developed hyperchloremia and required hyperosmolar treatment. 15 patients were randomized to the 23.4% NaCl group, and 17 patients were randomized to the 16.4% NaCl/Na- acetate group. Although serum chloride levels increased similarly in both groups, the NaCl/Acetate group showed a significantly lower Cl− load at the end of the study period (978mEq vs. -
Clinical Physiology Aspects of Chloremia in Fluid Therapy: a Systematic Review David Astapenko1,2* , Pavel Navratil2,3, Jiri Pouska4,5 and Vladimir Cerny1,2,6,7,8,9
Astapenko et al. Perioperative Medicine (2020) 9:40 https://doi.org/10.1186/s13741-020-00171-3 REVIEW Open Access Clinical physiology aspects of chloremia in fluid therapy: a systematic review David Astapenko1,2* , Pavel Navratil2,3, Jiri Pouska4,5 and Vladimir Cerny1,2,6,7,8,9 Abstract Background: This systematic review discusses a clinical physiology aspect of chloride in fluid therapy. Crystalloid solutions are one of the most widely used remedies. While generally used in medicine for almost 190 years, studies focused largely on their safety have only been published since the new millennium. The most widely used solution, normal saline, is most often referred to in this context. Its excessive administration results in hyperchloremic metabolic acidosis with other consequences, including higher mortality rates. Methods: Original papers and review articles eligible for developing the present paper were identified by searching online in the electronic MEDLINE database. The keywords searched for included hyperchloremia, hypochloremia, and compound words containing the word “chloride,” infusion therapy, metabolic acidosis, renal failure, and review. Results: A total of 21,758 papers published before 31 May 2020 were identified; of this number, 630 duplicates were removed from the list. Upon excluding articles based on their title or abstract, 1850 papers were screened, of which 63 full-text articles were assessed. Conclusions: According to the latest medical concepts, dyschloremia (both hyperchloremia and hypochloremia) represents a factor indisputably having a negative effect on selected variables of clinical outcome. As infusion therapy can significantly impact chloride homeostasis of the body, the choice of infusion solutions should always take into account the potentially adverse impact of chloride content on chloremia and organ function. -

Renal Tubular Acidosis in Children: State of the Art, Diagnosis and Treatment
www.medigraphic.org.mx Bol Med Hosp Infant Mex 2013;70(3):178-193 REVIEW ARTICLE Renal tubular acidosis in children: state of the art, diagnosis and treatment Ricardo Muñoz-Arizpe,1 Laura Escobar,2 Mara Medeiros3 ABSTRACT Overdiagnosis of renal tubular acidosis (RTA) has been recently detected in Mexican children, perhaps due to diagnostic errors as well as due to a lack of knowledge regarding the pathophysiology and molecular biochemistry involved in this illness. The objective of the present study is to facilitate the knowledge and diagnosis of RTA, a clinical condition infrequently seen worldwide. RTA is an alteration of the acid-base equilibrium due to a bicarbonate wasting in the proximal renal tubules [proximal RTA, (pRTA) or type 2 RTA] or due to a distal nephron hy- drogen ion excretion defect [distal RTA (dRTA) or type 1 RTA]. Hyperkalemic, or type 4 RTA, is due to alterations in aldosterone metabolism. RTA may be primary, secondary, acquired or hereditary and frequently presents secondary to an array of systemic diseases, usually accom- panied by multiple renal tubular defects. The main defect occurs in the transmembrane transporters such as carbonic anhydrase (CA I and + - - + - II), H -ATPase, HCO3 /Cl (AE1) exchanger and Na /HCO3 (NBCe1) cotransporter. Diagnosis should include the presence of hyperchloremic metabolic acidosis with normal serum anion gap (done in an arterial or arterialized blood sample), lack of appetite, polyuria, thirst, growth failure, and rickets; nephrocalcinosis and renal stones (in dRTA); abnormal urine anion gap and abnormal urine/serum pCO2 gradient. Diagnosis of a primary systemic disease must be made in cases of secondary RTA. -
Oxytocin Regulates the Expression of Aquaporin 5 in the Latepregnant Rat
RESEARCH ARTICLE Molecular Reproduction & Development 81:524–530 (2014) Oxytocin Regulates the Expression of Aquaporin 5 in the Late-Pregnant Rat Uterus ESZTER DUCZA,* ADRIENN B. SERES, JUDIT HAJAGOS-TOTH, GEORGE FALKAY, AND ROBERT GASPAR Department of Pharmacodynamics and Biopharmacy, Faculty of Pharmacy, University of Szeged, Szeged, Hungary SUMMARY Aquaporins (AQPs) are integral membrane channels responsible for the transport of water across a cell membrane. Based on reports that AQPs are present and accumulate in the female reproductive tract late in pregnancy, our aim was to study the expression of AQP isoforms (AQP1, 2, 3, 5, 8, and 9) at the end of pregnancy in rat in order to determine if they play a role in parturition. Reverse-transcriptase PCR revealed that specific Aqp mRNAs were detectable in the myometrium of non- pregnant and late-pregnancy (Days 18, 20, 21, and 22 of pregnancy) rat uteri. The expression of Aqp5 mRNA and protein were most pronounced on Days 18À21, and were dramatically decreased on Day 22 of pregnancy. In contrast, a significant increase was found in the level of Aqp5 transcript in whole-blood samples ÃCorresponding author: on the last day of pregnancy.The effect of oxytocin on myometrial Aqp5 expression in Department of Pharmacodynamics an organ bath was also investigated.

Abstract: Nowadays, humanity faces one of the most serious health crises, the severe acute respi- ratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. The severity of coronavirus disease 2019 (COVID-19) pandemic is related to the high rate of interhuman transmission of the virus, variability of clinical presentation, and the absence of specific therapeutic methods. COVID-19 can manifest with non-specific symptoms and signs, especially among the elderly. In some cases, the clinical manifestations of hyponatremia may be the first to appear.
