Guidelines for the Management of Hyponatraemia in Hospitalised Patients
Guidelines for the management of hyponatraemia in hospitalised patients Authors: V Mishra Aims: To provide guidelines for appropriate investigations and treatment of hyponatraemia in hospitalised patients. Normal range Mild Moderate hyponatraemia Severe hyponatraemia hyponatraemia 135-146 mmol/L 130-135 mmol/L 120-129 mmol/L <120 mmol/L Evaluation of hyponatraemia STEP 1: Rule out artefactual causes Is the patient on IV fluids? If so, could the sample have been taken “downstream” from the infusion site? Could the sample have been taken from the same line? STEP 2: Clinical history Check fluid balance to exclude fluid overload Is the patient diabetic? Hyperglycemia may cause dilutional hyponatraemia and increased urinary loss of sodium Correct serum sodium for hyperglycemia (rise in plasma glucose >5.5mmol/L) by using equation given in (Appendix 1) Consider medications (Table 1). In some cases, stopping the medication or changing to an alternative that does not cause hyponatraemia may be sufficient. Monitor sodium concentrations to assess the effects of this management. It may take several days for the sodium to normalise after withdrawing medications Review clinical history for relevant conditions (such as congestive cardiac failure, kidney disease, liver failure, lung pathology) Loss of weight /appetite: investigate for malignancy 1 Table 1: Drugs known to cause hyponatraemia Drug group Examples known to causecause hyponatraemia (other compounds may exist) TThiazidehiazide diuretics Bendroflumethiazide, Metolazone, Indapamide, -
DIURETICS Diuretics Are Drugs That Promote the Output of Urine Excreted by the Kidneys
DIURETICS Diuretics are drugs that promote the output of urine excreted by the Kidneys. The primary action of most diuretics is the direct inhibition of Na+ transport at one or more of the four major anatomical sites along the nephron, where Na+ reabsorption takes place. The increased excretion of water and electrolytes by the kidneys is dependent on three different processes viz., glomerular filtration, tubular reabsorption (active and passive) and tubular secretion. Diuretics are very effective in the treatment of Cardiac oedema, specifically the one related with congestive heart failure. They are employed extensively in various types of disorders, for example, nephritic syndrome, diabetes insipidus, nutritional oedema, cirrhosis of the liver, hypertension, oedema of pregnancy and also to lower intraocular and cerebrospinal fluid pressure. Therapeutic Uses of Diuretics i) Congestive Heart Failure: The choice of the diuretic would depend on the severity of the disorder. In an emergency like acute pulmonary oedema, intravenous Furosemide or Sodium ethacrynate may be given. In less severe cases. Hydrochlorothiazide or Chlorthalidone may be used. Potassium-sparing diuretics like Spironolactone or Triamterene may be added to thiazide therapy. ii) Essential hypertension: The thiazides usually sever as primary antihypertensive agents. They may be used as sole agents in patients with mild hypertension or combined with other antihypertensives in more severe cases. iii) Hepatic cirrhosis: Potassium-sparing diuretics like Spironolactone may be employed. If Spironolactone alone fails, then a thiazide diuretic can be added cautiously. Furosemide or Ethacrymnic acid may have to be used if the oedema is regractory, together with spironolactone to lessen potassium loss. Serum potassium levels should be monitored periodically. -

Diuretics are widely used, and have several indications in different cardiovascular disorders, particularly in hypertension and heart failure. Despite the large number of available anti-hypertensive drugs, diuretics remained a cornerstone of hypertension treatment. In the current editorial, we assessed the actual place of different diuretics in the hypertension guidelines focusing on the concept of tailored approach in prescribing them for hypertensive patients. Keywords: Diuretics; Hypertension; Hydrochlorothiazide; Indapamide; Guidelines Introduction Diuretics represent a large and heterogeneous class of drugs, differing from each other by structure, site and mechanism of action. Diuretics are widely used, and have several indications in different cardiovascular disorders, particularly in hypertension and heart failure. Despite the large number of available anti-hypertensive drugs, diuretics remained a cornerstone of hypertension treatment [1]. Indeed, they are the second most commonly prescribed class of antihypertensive medication. For instance, 12% of US adults were prescribed a diuretic, and the relative increase in prescriptions from 1999 through 2012 was 1.4 [2]. -
Approach to Managing Patients with Sulfa Allergy Use of Antibiotic and Nonantibiotic Sulfonamides
CME Approach to managing patients with sulfa allergy Use of antibiotic and nonantibiotic sulfonamides David Ponka, MD, CCFP(EM) ABSTRACT OBJECTIVE To present an approach to use of sulfonamide-based (sulfa) medications for patients with sulfa allergy and to explore whether sulfa medications are contraindicated for patients who require them but are allergic to them. SOURCES OF INFORMATION A search of current pharmacology textbooks and of MEDLINE from 1966 to the present using the MeSH key words “sulfonamide” and “drug sensitivity” revealed review articles, case reports, one observational study (level II evidence), and reports of consensus opinion (level III evidence). MAIN MESSAGE Cross-reactivity between sulfa antibiotics and nonantibiotics is rare, but on occasion it can affect the pharmacologic and clinical management of patients with sulfa allergy. CONCLUSION How a physician approaches using sulfa medications for patients with sulfa allergy depends on the certainty and severity of the initial allergy, on whether alternatives are available, and on whether the contemplated agent belongs to the same category of sulfa medications (ie, antibiotic or nonantibiotic) as the initial offending agent. RÉSUMÉ OBJECTIF Proposer une façon d’utiliser les médicaments à base de sulfamides (sulfas) chez les patients allergiques aux sulfas et vérifier si ces médicaments sont contre-indiqués pour ces patients. SOURCES DE L’INFORMATION Une consultation des récents ouvrages de pharmacologie et de MEDLINE entre 1966 et aujourd’hui à l’aide des mots clés MeSH «sulfonamide» et «drug sensitivity» a permis de repérer plusieurs articles de revue et études de cas, une étude d’observation et des rapports d’opinion consensuelles (preuves de niveau III). -

Diuretics for Hypertension
The Rx Files: Q&A Summary March 1998, LDR DIURETICS IN THE TREATMENT OF HYPERTENSION: CURRENT STATUS 1. When are thiazide diuretics considered first line antihypertensives? Antihypertensive therapy should be individualized by choosing agents that have favorable effects on comorbid conditions. The recent JNC VI report1 recommends thiazides (or â Blockers) as first line agents in the treatment of uncomplicated hypertension except where contraindicated, not tolerated, or concurrent medical conditions favor use of alternate agents (see Appendix 1).1 Thiazide diuretics and â Blockers are the only antihypertensives that have been well documented in long-term controlled trials to reduce cardiovascular morbidity and mortality, particularly MI and stroke.2 Current large-scale trials are underway to determine if other classes of antihypertensives have similar benefits. Thiazides are particularly effective in elderly patients with isolated systolic hypertension.1 They also have favorable effects in patients at risk of osteoporosis. When not used for initial monotherapy, addition of a low dose diuretic as the second agent is recommended unless contraindicated.1 2. Are low dose thiazides as effective in treating hypertension as higher doses? Doses as low as 12.5-25mg of hydrochlorothiazide (HCT), given once daily, have been as effective in lowering blood pressure as higher doses.3 In fact, doses above 25mg have little added benefit but greater incidence of adverse effects.3,7 A dose of 6.25mg HCT can often significantly augment the response of other antihypertensives when used in combination. 3. What about the adverse metabolic effects of thiazides? In doses of 25mg or less, incidence of hypokalemia is <5%, and few patients will actually require potassium supplementation or addition of a K+ sparing diuretic. -

Choice of Medicines for Hypertension
CORRESPONDENCE Hypertension guidelines versus individual studies: Should we hang our hat on ALLHAT? Recommendations in Best Practice Journal are tailored to the needs of primary care health professionals by incorporating information from guidelines, and where necessary, adapting this to a New Zealand context. Naturally, this guidance will sometimes differ from conclusions that are based on individual studies. “Hypertension in Adults: The silent killer”, BPJ 54 (Aug, 2013) was largely based on the United Kingdom National Choice of medicines for hypertension Institute of Health and Care Excellence (NICE) guidelines Dear Editor for the clinical management of primary hypertension in There were a few problems with the article: “Hypertension in adults (2011).1 The discrepancies highlighted between the adults: the silent killer”, BPJ 54 (Aug, 2013). I usually find the bpacnz recommendations in the Best Practice Journal article and the resources well written and evidence based. In this review there results of the Antihypertensive and Lipid Lowering Treatment were a number of key errors: to Prevent Heart Attack Trial (ALLHAT) represent differences in 1. Start with an ACE inhibitor or calcium channel blocker. clinical/expert opinion rather than “key errors”. Ironically there is data that neither of these medications are more effective than chlorthalidone – a thiazide-like diuretic: 1. We agree that the ALLHAT trial published in 2002 did see ALLHAT study, JAMA 2002;288:2981-97, which found, not show evidence of superiority for thiazide-like diuretics albeit for the secondary but important outcome of combined over ACE inhibitors or calcium channel blockers.
