Introduction: Hyponatremia and/or hypoglycorrhachia are commonly encountered biochemical derangements during the acute stage of childhood tuberculous meningitis (TBM). Few studies have explored the correlation between these derangements and the staging of TBM disease (severity), or explored their role as biomarkers for vascular ischemic events, hydrocephalus, or seizures.Methods: We aimed to identify the prevalence and the correlation between serum hyponatremia (mild, moderate and severe) and/or hypoglycorrhachia in relation to clinical TBM features such as stage of disease, seizures and stroke in children diagnosed with definite and probable TBM, between 1985 and 2015, at Tygerberg Hospital, Cape town, South Africa.Results: The prevalence of hyponatremia was 344 out of 481 (71.5%) patients; 169 (49.1%) had mild hyponatremia, 146 (42.4%) moderate hyponatremia and 29 (8.4%) severe hyponatremia. Children with severe hyponatremia had higher frequency of stroke [odds ratio (OR) 4.36, 95% confidence interval (CI) 1.24–15.35; p = 0.01], brainstem dysfunction (OR 7.37, 95% CI 2.92–18.61; p < 0.01), cranial nerve palsies (OR 2.48, 95% CI 1.04–5.91; p = 0.04) and non-communicating hydrocephalus (OR 2.66, 95% CI 1.09–6.44; p = 0.03). Children with moderate hyponatremia and mild hyponatremia compared to those without hyponatremia similarly were more likely to exhibit signs of brainstem dysfunction (OR 1.91, 95% CI 1.11–3.28; p = 0.02) and hydrocephalus (OR 3.18, 95% CI 1.25–8.09; p = 0.01), respectively. On multivariable analysis only brainstem dysfunction was significantly associated with severe hyponatremia [adjusted odds ratio (aOR) 4.46, 95% CI 1.62–12.30; p < 0.01]. Children with hypoglycorrhachia compared to normoglycorrhachia were more likely to have had longer symptom duration prior to admission (OR 1.87, 95% CI 1.09–3.20; p = 0.02), non-communicating hydrocephalus (OR 1.64, 95% CI 0.99–2.71; p = 0.05), higher cerebrospinal white cell counts (OR 3.00, 95% CI 1.47–6.12; p < 0.01) and higher CSF protein concentrations (OR 2.51, 95% CI 1.49–4.20; p < 0.01). On multivariable analysis raised CSF protein concentration >1 g/L was significantly associated with hypoglycorrhachia (aOR 2.52, 95% CI 1.44–4.40; p < 0.01). Death rates did not differ by sodium level category or presence of hypoglycorrachia, however an increasing trend of children that had demised was noted the more severe the sodium category.Conclusion: Hyponatremia and/or hypoglycorrhachia occur in more than two-thirds of children with TBM. Severe TBM disease complications such as brainstem dysfunction was associated with moderate hyponatremia, while severe hyponatremia was associated with brainstem dysfunction, stroke, cranial nerve palsies and non-communicating hydrocephalus. Cerebrospinal fluid (CSF) glucose depletion correlated with non-communicating hydrocephalus and increased CSF inflammation.

Acute intermittent porphyria (AIP) is a rare autosomal dominant and the most severe form of the inherited hepatic porphyrias, affecting mainly young women. We present the case of an 18-year-old female who presented with severe abdominal pain, purple urine, autonomic dysfunction, and severe hyponatremia, seizures on further evaluation came out to be a case of AIP. This case report is a reminder to keep AIP among the differentials in young female patients with a classic constellation of abdominal urine discoloration syndrome of inappropriate secretion of antidiuretic hormone and autonomic dysfunction.

Hyponatremia is a common electrolyte disorder, especially in the frail elderly population. With the increasing number of surgeries in the aging population, hyponatremia is frequently encountered by anesthesiologists and surgeons. Unfortunately, management of hyponatremia is often complex in the elderly population as it is often multifactorial, and they are physiologically susceptible. While it is well known that preoperative hyponatremia is associated with increased perioperative morbidity and mortality, a lack of recommendations or guidelines adds to the dilemma in managing such cases. The most common cause of chronic hyponatremia in the elderly is the syndrome of inappropriate antidiuretic hormone (SIADH), which can be resistant to conventional treatment. On the other hand, paraneoplastic SIADH leading to hyponatremia is rare, and surgery may be the only option available for its correction. We present a case of a 78- years-gentleman to highlight such a dilemma. He was diagnosed with renal cell carcinoma and had chronic refractory severe hyponatremia despite treatment with fluid restriction, low dose hydrocortisone, tolvaptan, and 3% sodium chloride.

Amiodarone is an antiarrhythmic drug belonging to Vaughan-Williams Class III with additional Class IV effects, which is known to cause many adverse drug reactions (ADRs) necessitating close monitoring. In about 20% of patients, their therapy is discontinued due to adverse effects such as hepatic impairment, thyroid dysfunction, and several pulmonary complications. Although dyselectrolytemia is a common adverse reaction reported with many cardiac medications, the incidence of hyponatremia associated with amiodarone intake is not reported widely in the literature. We are reporting a case of a 73-year-old female patient, with hypertension and ischemic heart disease (IHD) receiving oral amiodarone, presenting with severe hyponatremia, requiring recurrent hospitalization. Amiodarone was found to be responsible after evaluating for the possible causes of hyponatremia. As the incidence of amiodarone-associated hyponatremia is unknown, and not many cases are reported, this case report serves to sensitize the clinician to consider amiodarone-induced hyponatremia as one of the differential diagnoses in cases of unexplained hyponatremia.
