ABSTRACT
BACKGROUND: This study aimed to compare the effect of two methods of maintenance intravenous fluid therapy on hyponatremia in hospitalized infants with sepsis. METHODS: In a double-blinded randomized clinical trial, 60 term infants with sepsis were enrolled. Blood samples were taken to determine sodium, potassium, Creatinine, and BUN levels before the initiation of treatment. Urine samples were taken to assess specific gravity and urinary output. Infants in the intervention group received half saline in 10% dextrose and infants in the control group were assigned to receive the conventional solution as maintenance. The above indicators were re-evaluated 24 and 48 h after the initiation of treatment. Two groups were compared concerning the incidence of hyponatremia, and other criteria such as urinary output and urinary specific gravity, blood urea nitrogen (BUN), and creatinine levels. RESULTS: Hyponatremia was more common in the control group. Sodium levels were significantly higher in half saline recipients 24 h (137.83 ± 2.86 vs. 134.37 ± 1.91 mmol/L), and 48 h (138.10 ± 2.41 vs. 133.66 ± 1.98 mmol/L) after treatment (P < 0.001). Although BUN in the intervention group was significantly higher in comparison to the control group, the difference in urinary output, urine specific gravity, potassium, and Creatinine levels were not significant in the two groups. CONCLUSIONS: The use of a half-saline solution as maintenance fluid reduces the risk of hyponatremia after 48 h when compared to 0.18%NaCl. TRIAL REGISTRATION: This has been registered at Iranian Registry of Clinical Trials (Retrospectively registered, Registration date: 2017-10-12, identifier: IRCT2017053034223N1, https://irct.behdasht.gov.ir/trial/26204 ).

Purpose: Chest computed tomography (CT) is used to determine the severity of COVID-19 pneumonia, and pneumonia is associated with hyponatremia. This study aims to explore the predictive value of the semi-quantitative CT visual score for hyponatremia in patients with COVID-19 to provide a reference for clinical practice. Methods: In this cross-sectional study, 343 patients with RT-PCR confirmed COVID-19, all patients underwent CT, and the severity of lung lesions was scored by radiologists using the semi-quantitative CT visual score. The risk factors of hyponatremia in COVID-19 patients were analyzed and combined with laboratory tests. The thyroid function changes caused by SARS-CoV-2 infection and their interaction with hyponatremia were also analyzed. Results: In patients with SARS-CoV-2 infection, the total severity score (TSS) of hyponatremia was higher [M(range), 3.5(2.5-5.5) vs 3.0(2.0-4.5) scores, P=0.001], implying that patients with hyponatremia had more severe lung lesions. The risk factors of hyponatremia in the multivariate regression model included age, vomiting, neutrophils, platelet, and total severity score. SARS-CoV-2 infection impacted thyroid function, and patients with hyponatremia showed a lower free triiodothyronine (3.1 ± 0.9 vs 3.7 ± 0.9, P=0.001) and thyroid stimulating hormone level [1.4(0.8-2.4) vs 2.2(1.2-3.4), P=0.038]. Conclusion: Semi-quantitative CT score can be used as a risk factor for hyponatremia in patients with COVID-19. There is a weak positive correlation between serum sodium and free triiodothyronine in patients with SARS-CoV-2 infection.

Hyponatraemia has indeed been extensively studied from multiple angles, including volume status, tonicity, and aetiology; however, the specific consideration of the osmolar gap (OG) within the context of hyponatraemia and its potential impact on their overall outcomes received limited attention in research. The current study represents an effort to address this gap in our understanding. This prospective exploratory study was conducted on adults aged 14 years and older at the Indus Hospital, Karachi, from 2017 to 2020. The study involved categorising severity of hyponatraemia and volume status. The osmolar gap (OG) was calculated and categorised as either increased (OG>10) or normal (OG<10). Among the 262 patients included in the study, there were 139 females and 123 males. Elevated OG was observed in 141(53.8%) patients. There were 28 (10.7%) recorded fatalities and majority of these individuals had an elevated OG. These findings underscore the importance for clinicians to consider the osmolar gap when managing patients with hyponatraemia.

We report the case of a term neonate who was somnolent at birth with ventilatory distress and experienced 2 seizures shortly after delivery. Laboratory tests revealed the neonate had a serum sodium of 113 mmol/L. The seizures stopped after treatment with midazolam, and the sodium was corrected slowly with 3% hypertonic saline without further sequelae. The severe neonatal hyponatremia and seizures were attributed to maternal consumption of excessive amounts of coconut water during labor. This case demonstrates the importance of careful consideration of both fluid volume and fluid electrolyte composition during labor to prevent adverse maternal and neonatal outcomes.

Hyponatraemia, defined as sodium concentration below 135 mmol/l, is one of the most common electrolyte imbalances. Differential diagnosis of hyponatraemia is difficult. We describe 3 cases of children with transient, severe hyponatraemia (< 125 mmol/l). While diagnosing hyponatraemia, it is of major importance to carefully ask in the anamnesis about habits related to the amount of fluid intake and the type of consumed fluids. It should also be noted that a frequent procedure during an infection is to increase fluid ingesting as a prevention of dehydration. One, however, should remember about the possibility of inducing water poisoning in a patient consuming excessive amounts of hypotonic fluids, especially when exposed to non-osmotic antidiuretic hormone stimulus, such as an acute infection or stress, and/or reduced renal excretory capacity. Only the presence of polyuria does not justify a diagnosis of arginine vasopressin deficiency (AVP-D), and especially the implementation of desmopressin treatment before all diagnostic procedures are completed, specifically in the case of hyponatraemia. Desmopressin can be used simultaneously with intravenous 3% saline solution only in the treatment of a very severe hyponatraemia, to avoid overcorrection of natraemia. In patients after profound hyponatraemia, polyuria can be observed after normalisation of fluid intake, but it is temporary.

Hyponatremia, though common in women with preeclampsia, has not been well studied. Our primary objectives are to assess the clinical characteristics and emergency therapy applied to subjects diagnosed with preeclampsia. We hypothesize that hyponatremia present in preeclamptic patients with severe features is associated with greater use of emergency hypertensives, antenatal steroids, and cesarean delivery. This is a retrospective descriptive study utilizing an electronic health record database (TriNetX ®). We collected and evaluated the following data of subjects aged 15 to 54 years with preeclampsia with severe features diagnosis: demographics, diagnostic codes, medication codes, procedure codes, deaths, and laboratory results. A total of 2,901 subjects [215 (7.4%)] with a sodium level below 134 mEq/L and [2686 (92.6%)] with a sodium level above 135 mEq/L were included. A higher proportion of subjects in the below 134 sodium group received emergency antihypertensives [165 (76.7%) versus 1811 (67.4%), p = 0.01], antenatal steroids [103 (47.9%) versus 953 (35.5%), p = 0.001], and cesarean section [27 (12.6%) versus 97 (3.6%), p = <0.001]. We found that hyponatremia may be associated with emergency antihypertensive use, antenatal steroid use, and cesarean section in patients with preeclampsia with severe features. Future research is needed to determine if routine sodium levels assessed in preeclamptic subjects with severe features identify subjects at risk of receiving these treatments.

BACKGROUND: The incidence of dysnatremia in children with acute gastritis/gastroenteritis varies, and factors associated with either dysnatremia or hyponatremia at presentation have not been identified clearly. METHODS: This retrospective study included patients aged 1 month to 18 years hospitalized for community-acquired acute gastritis/gastroenteritis from January to October 2016. Factors associated with dysnatremia at presentation were identified using multivariable analysis. RESULTS: Among the 304 children included, the median age was 2.2 (1.0, 4.2) years. The incidence of dysnatremia at presentation was 17.1% (hyponatremia 15.8%; hypernatremia 1.3%). Patients who had moderate (p = 0.03) and severe dehydration (p = 0.04) and presented with vomiting and diarrhea simultaneously (p = 0.03) were associated with dysnatremia at presentation. Patients presented with vomiting and diarrhea simultaneously was associated with hyponatremia at presentation (p = 0.02). CONCLUSIONS: Dysnatremia was common in children with acute gastritis/gastroenteritis. Moderate to severe dehydration and the presence of vomiting and diarrhea simultanously were significantly associated with dysnatremia at presentation. Furthermore, presenting with vomiting and diarrhea silmutaneously was associated with hyponatremia at presentation. Serum electrolytes should be monitored in patients with those conditions.

The objective of the present study was to evaluate the risk factors and outcomes associated with hyponatremia in patients with Guillain-Barré syndrome (GBS). We retrospectively studied 80 consecutive patients with GBS who visited our hospital and compared clinical, laboratory, and electrophysiological findings of patients with and without hyponatremia. Disability was evaluated using the Hughes grading system. Of the 80 patients, 18 (23%) had hyponatremia. Hyponatremia was significantly associated with older age (P = 0.003), urinary retention (P < 0.0001), Hughes grade ≥ 4 at admission and nadir (P = 0.003 and P < 0.001, respectively), acute inflammatory demyelinating polyneuropathy subtype (P = 0.017), sepsis (P = 0.001), mechanical ventilator support (P = 0.013), longer hospitalization length of stay (P < 0.0001), and inability to walk independently at 6 months (P < 0.001). Multivariate analysis performed to assess the risk factors of hyponatremia revealed that urinary retention (odds ratio [OR] 30.7, 95% confidence interval [CI] 3.6-264.4; P = 0.002) and mechanical ventilator support (OR 13.8, 95% CI 1.6-118.0; P = 0.017) were significant independent risk factors of hyponatremia. In assessing the outcomes of patients with hyponatremia, multivariate analysis showed that hyponatremia was independently associated with hospitalization length of stay ≥ 60 days and inability to walk independently at 6 month, with the former showing statistical significance but the latter not (OR 9.3, 95% CI 1.8-47.7; P = 0.007 and OR 4.9, 95% CI 0.9-26.3; P = 0.066, respectively). Therefore, we demonstrate that, along with mechanical ventilator support, urinary retention-possibly indicating autonomic dysfunction-is a risk factor of hyponatremia in GBS. Moreover, we confirm that hyponatremia is associated with poor outcome in GBS.

OBJECTIVES: Numerous studies have been conducted to investigate the effects of preoperative hyponatremia on survival after liver transplantation. The variable findings underscore the necessity for performing a systematic review to elucidate the potential effects of preoperative hyponatremia. MATERIALS AND METHODS: We searched PubMed, Scopus, Web of Science, Science Direct, Cochrane Library, and reference lists of articles for observational cohort studies that reported association between preopera-tive hyponatremia and survival after liver transplant in adults regardless of publication year. We used the random-effect model to pool the extracted data for meta-analysis. RESULTS: Meta-analyses of mean difference in serum sodium levels showed that nonsurviving recipients had 2.58 mEq/L lower preoperative serum sodium levels than surviving recipients (0.02; 95% CI, .33-4.83). Two observational methods were used to assess survival after liver transplant of patients with preoperative hyponatremia. According to meta-analyses, no dif-ference in survival was shown between recipients with and without preoperative hyponatremia (sodium> 130 mEq/L) (≤1 month : 0.69 [95% CI, 0.9-1.07], 3-month survival: 0.54 [95% CI, 0.95-1.02]). Second, when we compared posttransplant survival of recipients with preoperative hypo-natremia versus those with normal serum sodium levels (sodium = 130-145 mEq/L), we found that recipients with preoperative hyponatremia had lower survival after liver transplant than those with normal preoperative serum sodium levels. CONCLUSIONS: Liver transplant recipients with preop-erative hyponatremia probably have shorter survival posttransplant than those with normal preoperative serum sodium level.

INTRODUCTION: Hyponatremia, defined as a serum sodium concentration <135 mmol/l, is a frequent electrolyte disorder in patients presenting to an emergency department (ED). In this context, appropriate diagnostic and therapeutic management is rarely performed and challenging due to complex pathophysiologic mechanisms and a variety of underlying diseases. OBJECTIVE: To implement a feasible pathway of central diagnostic and therapeutic steps in the setting of an ED. METHODS: We conducted a narrative review of the literature, considering current practice guidelines on diagnosis and treatment of hyponatremia. Underlying pathophysiologic mechanisms and management of adverse treatment effects are outlined. We also report four cases observed in our ED. RESULTS: Symptoms associated with hyponatremia may appear unspecific and range from mild cognitive deficits to seizures and coma. The severity of hyponatremia-induced neurological manifestation and the risk of poor outcome is mainly driven by the rapidity of serum sodium decrease. Therefore, emergency treatment of hyponatremia should be guided by symptom severity and the assumed onset of hyponatremia development, distinguishing acute (<48 hours) versus chronic hyponatremia (>48 hours). CONCLUSIONS: Especially in moderately or severely symptomatic patients presenting to an ED, the application of a standard management approach appears to be critical to improve overall outcome. Furthermore, an adequate work-up in the ED enables further diagnostic and therapeutic evaluation during hospitalization.

Cystic fibrosis is a multisystem disease with extremely variable onset, symptoms and course. One of the onset modality but also a complication of the disease is the pseudo-Bartter syndrome, characterized by hyponatremia, hypochloremic dehydration and metabolic alkalosis in absence of any renal disease. This syndrome occurs more frequently in the first year of life and has a peak in the summer. In this article, we describe two cases of cystic fibrosis associated with pseudo-Bartter syndrome in childhood. Excluding every possible cause of metabolic alkalosis associated with hyponatremia was crucial for our diagnostic pathway, and the experience gained with the first case helped a lot with the second one.

Background and Objectives: The relationship between histidine-tryptophan-ketoglutarate (HTK)-induced hyponatremia and brain injury in adult cardiac surgery patients is unclear. This study analyzed postoperative neurological outcomes after intraoperative HTK cardioplegia infusion. Materials and Methods: A prospective cohort study was conducted on 60 adult patients who underwent cardiac surgery with cardiopulmonary bypass. Of these patients, 13 and 47 received HTK infusion and conventional hyperkalemic cardioplegia, respectively. The patients' baseline characteristics, intraoperative data, brain injury markers, Mini-Mental State Examination (MMSE) scores, and quantitative electroencephalography (qEEG) data were collected. Electrolyte changes during cardiopulmonary bypass, the degree of hyponatremia, and any associated brain insults were evaluated. Results: The HTK group presented with acute hyponatremia during cardiopulmonary bypass, which was intraoperatively corrected through ultrafiltration and normal saline administration. Postoperative sodium levels were higher in the HTK group than in the conventional cardioplegia group. The change in neuron-specific enolase levels after cardiopulmonary bypass was significantly higher in the HTK group (p = 0.043). The changes showed no significant differences using case-control matching. qEEG analysis revealed a significant increase in relative delta power in the HTK group on postoperative day (POD) 7 (p = 0.018); however, no significant changes were noted on POD 60. The MMSE scores were not significantly different between the two groups on POD 7 and POD 60. Conclusions: HTK-induced acute hyponatremia and rapid correction with normal saline during adult cardiac surgeries were associated with a potential short-term but not long-term neurological impact. Further studies are required to determine the necessity of correction for HTK-induced hyponatremia.

Hyponatremia is the most common disorder of electrolyte imbalances. It is necessary to develop new type of diuretics to treat hyponatremia without losing electrolytes. Urea transporters (UT) play an important role in the urine concentrating process and have been proved as a novel diuretic target. In this study, rat and mouse syndromes of inappropriate antidiuretic hormone secretion (SIADH) models were constructed and analyzed to determine if UTs are a promising drug target for treating hyponatremia. Experimental results showed that 100 mg/kg UT inhibitor 25a significantly increased serum osmolality (from 249.83 ± 5.95 to 294.33 ± 3.90 mOsm/kg) and serum sodium (from 114 ± 2.07 to 136.67 ± 3.82 mmol/L) respectively in hyponatremia rats by diuresis. Serum chemical examination showed that 25a neither caused another electrolyte imbalance nor influenced the lipid metabolism. Using UT-A1 and UT-B knockout mouse SIADH model, it was found that serum osmolality and serum sodium were lowered much less in UT-A1 knockout mice than in UT-B knockout mice, which suggest UT-A1 is a better therapeutic target than UT-B to treat hyponatremia. This study provides a proof of concept that UT-A1 is a diuretic target for SIADH-induced hyponatremia and UT-A1 inhibitors might be developed into new diuretics to treat hyponatremia.

A 60-year-old man was referred to our hospital presenting with unconsciousness due to severe hyponatremia. The twelvelead ECG on admission exhibited prominent J waves in the inferolateral leads. During the treatment for hyponatremia, ventricular fibrillation (VF) occurred and the electrogram (ECG) after the VF incident exhibited marked ST elevation in the inferolateral leads. An Ach provocation test induced vasospasms in the right and left coronary arteries and J wave augmentation, suggesting a high risk for vasospastic angina. Finally, a subcutaneous implantable cardioverter defibrillator was implanted in the patient. We hereby discuss the possible contribution of hyponatremia to VF episodes in early repolarization syndrome based on the present case.

Boswellia serrata is an herbal extract from the Boswellia serrata tree that has anti-inflammatory and analgesic properties and alleviates pain caused by rheumatoid arthritis, gout, osteoarthritis, and sciatica. Syndrome of inappropriate antidiuretic hormone secretion accompanied by hyponatremia, seizures, and rhabdomyolysis as a manifestation of Boswellia serrata intoxication has not been reported previously. A 38-year-old female suffered clinically isolated syndrome and has since been regularly taking B. serrata capsules (200mg/d) to strengthen her immune system. She experienced hypersensitivity to light, ocular pain, nausea, dizziness, and lower limb weakness four days after receiving her first BNT162b2 vaccine dose, and she increased the dosage of B. serrata to five capsules (1000mg/d) one week after vaccination. After taking B. serrata at a dosage of 1000mg/d for 3 weeks, she was admitted to the intensive care unit because of a first, unprovoked generalized tonic-clonic seizure. The patient's workup revealed syndrome of inappropriate antidiuretic hormone secretion, which resolved completely upon treatment and discontinuation of B. serrata. In summary, B. serrata potentially causes syndrome of inappropriate antidiuretic hormone secretion when it is taken at high doses. Patients should not self-medicate.

A 37-year-old woman presented with nausea, vomiting and headache. She was found to be profoundly hyponatraemic with a sodium of 121 mmol/L, which deteriorated following a fluid challenge. An initial hyponatraemia screen identified adrenal insufficiency, with cortisol of 48 nmol/L. History confirmed she had been taking the herbal plant, ashwagandha. After 3 days of fluid restriction and steroid replacement, her sodium returned to normal (139 mmol/L). This article reviews the possible harmful effects of over-the-counter herbal remedies and highlights the importance of considering a wide differential diagnosis in patients presenting with non-specific symptoms.
