Syndrome of inappropriate secretion of antidiuretic hormone in tuberculous meningitis
Pediatric Nephrology
We describe the first reported case of a syndrome of inappropriate secretion of antidiuretic hormone (SIADH) induced by low-dose tacrolimus in a patient with autoimmune disease. A 41-year-old man with systemic lupus erythematosus (SLE) developed hyponatremia induced by SIADH after administration of tacrolimus (0.06 mg/kg per day). In this case, the hyponatremia promptly resolved upon withdrawal of tacrolimus. This case strongly suggests that SIADH is a potentially important complication of tacrolimus administration, irrespective of dosage, and should be borne in mind whenever the drug is used.

Intracranial pressure (ICP) monitored shortly after admission over a period of 1 h in 31 children with tuberculous meningitis (TBM) was significantly higher (median 22.5 mmHg, range 8.4-50.9 mmHg) in 19 children with laboratory evidence of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) than in 12 children without such evidence (median 16.2 mmHg, range 5.8-42.5 mmHg; P=0.027). Neither plasma nor cerebrospinal fluid arginine vasopressin (AVP) was related to ICP (r= 0.33 and 0.13 respectively). Mean arterial pressure (MAP) was measured in 23 children and a moderate correlation was found with plasma AVP (r=0.62; P=0.0019). In TBM, plasma AVP may be secreted as a response to raised ICP in an effort to raise MAP and maintain cerebral perfusion pressure. In this setting excess fluid may be inappropriately retained, leading to hyponatremia and hypo-osmolemia.
Cerebral salt wasting in tuberculous meningitis: Two cases and review of the literature. Case Report
PubMed, 2015
Cerebral salt wasting syndrome (CSWS) is characterized by severe natriuresis and volume depletion in the presence of cerebral pathology. In literature, there are few reports about tuberculous meningitis and cerebral CSWS. In this article, we report two tuberculous meningitis cases with CSWS and present a review of the literature on this topic. Cerebral salt wasting diagnosis was based on hyponatraemia associated with high urinary sodium excretion and inappropriately high urine output in the presence of dehydration. Treatment was made with sodium-fluid replacement plus fludrocortisone therapy in both cases. In agreement with the literature we argue that cerebral salt wasting syndrome might be more common than the syndromes of inappropriate antidiuretic hormone secretion (SIADH) in cerebral disorders. Differentiating the cerebral salt wasting syndrome from the SIADH is very important because unrecognized cerebral salt wasting syndrome can lead to inadequate management and result in unnecessary hyponatremia-related morbidity. The electrolyte and hydration status of patients should be monitored closely in patients with tuberculous meningitis.
Serum sodium and osmolal changes in tuberculous meningitis
Indian pediatrics, 1994
Twenty children from 2 months to 7 years (mean age 2.74 years +/- 1.62) diagnosed to have tuberculous meningitis (TBM) were evaluated for serial serum sodium levels and osmolality of cerebrospinal fluid (CSF), serum and urine on admission and the results compared with 20 age and nutritionally matched controls, and these investigations repeated on day 3 and day 10. Mean serum sodium levels (130.7 +/- 6.26 mEq/L), and osmolality of CSF (272.0 +/- 7.0 mOsm/kg) and serum (275.5 +/- 6.09 mOsm/kg) were significantly lower (p < 0.001) than in controls. Hyponatremia was detected in 65% of cases on admission, 47% on day 3 and in 30.8% on day 10. All the patients with hyponatremia had biochemical evidence of syndrome of inappropriate secretion of antidiuretic hormone (SIADH) on admission. Incidence of SIADH gradually decreased to 41.2% on day 3 and 15.4% on day 10. In some of the cases serum sodium levels and osmolality of serum and CSF took about 3 weeks to return to normal. CSF osmolalit...
Frequency of Hyponatremia in Tuberculous Meningitis Patients
Pakistan Journal of Medical and Health Sciences
Back Ground: A severe inflammation of the meninges is often referred to as meningitis. Hyponatremia has been associated with tuberculous meningitis in numerous studies. Objective: To assess the frequency of hyponatremia in tuberculous meningitis patients Methodology: This cross sectional study was carried out at the department of Neurology Bolan Medical Complex Hospital, Fatima Jinnah Institute of Chest Diseases and Sheikh Khalifa Bin Zayyed Al Nahyan Medical Complex Quetta for duration of one year from September 2021 to September 2022. All the required data like name, gender and presence or absence of hyponatremia were documented in a special proforma designed for this research. Data analysis was carried out by using SPSS version 23. Results: In our study, totally 210 patients were included. The male participants in our study were 94 (44.76%) while female participants were 116 (55.24%). The mean sodium level in serum was observed to be 133 with SD of ± 4.29. The overall frequency o...
Cerebral salt wasting in tuberculous meningitis: treatment with fludrocortisone
Annals of Tropical Paediatrics, 2005
Three cases of cerebral salt wasting complicating tuberculous meningitis are described. Diagnosis was based on hyponatraemia associated with high urinary sodium excretion and inappropriately high urine output in the presence of dehydration. Treatment with fludrocortisone resulted in sodium and fluid homeostasis.
Bladder dysfunction and urodynamic study in tuberculous meningitis
Journal of the Neurological Sciences, 2013
Background: Micturitional disturbances in tuberculous meningitis have been reported infrequently and that too without urodynamic studies. Bladder dysfunction in tuberculous meningitis is often considered secondary to tuberculous radiculomyelopathy. We, in this study, evaluated the incidence and pattern of bladder dysfunction in tuberculous meningitis. Materials and method: In this prospective study, 51 patients were included. In addition to clinical evaluation, patients were subjected to a urodynamic study along with magnetic resonance imaging (MRI) of brain and spine. Patients were followed up for 6 months. A follow-up urodynamic study was performed after 6 months. Results: Out of 51 patients, urinary symptoms were present in one-third of the patients. Approximately, 70% (36) of the patients had urodynamic abnormalities. The commonest (22/51) urodynamic abnormality was detrusor hyporeflexia/areflexia. Other urodynamic abnormalities were neurogenic detrusor overactivity in 10, detrusor sphincter dyssynergia in 6, normal detrusor activity in 19, reduced bladder sensation in 12, raised cystometric capacity in 9, and larger volumes of post-void residual urine in 12 patients. Six patients were unable to void on command. Three patients with neurogenic detrusor overactivity had leak during study. MRI showed spinal meningeal enhancement in 37, lumbosacral arachnoiditis in 25, myelitis in 12 patients, CSF loculations in 6, and cord atrophy in 5 patients. Spinal arachnoiditis and urinary symptoms showed significant association with urodynamic abnormalities. Follow-up urodynamic study showed resolution of urodynamic abnormalities in 72.6% of the patients with treatment. Seven (28%) patients, with normal baseline urodynamic findings, paradoxically developed new abnormalities. Conclusion: Bladder dysfunctions, in tuberculous meningitis, are frequently encountered. A significant association exists between urodynamic abnormalities and tuberculous lumbosacral arachnoiditis and myeloradiculopathy.
