Ryoo J, Choi A, Cho H, Bae W. Relationship of severity of hyponatremia and adverse outcomes in children visiting the emergency department. Front Pediatr 2024; 12:1379727. [PMID: 38948239 PMCID: PMC11211560 DOI: 10.3389/fped.2024.1379727] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Accepted: 06/03/2024] [Indexed: 07/02/2024] Open
Abstract
Mild hyponatremia is often found in patients visiting pediatric emergency departments (PEDs), but there are few large-scale studies on its association with adverse outcomes, including mortality. We conducted this study to identify the association of mild hyponatremia with adverse outcome. This retrospective observational study included children under 18 years of age visiting the PED at a tertiary hospital. We used electronic medical record data from January 1, 2009 to December 31, 2020. Clinical outcomes, including ward admission, vasopressor administration, pediatric intensive care unit (PICU) admission, and mortality, were assessed for the total of 44,147 patients. Among these, 1,639 (3.7%) were in the hyponatremia group, with 1,521 (3.4%) exhibiting mild hyponatremia. Mild hyponatremia was more prevalent in younger patients, particularly in the 1-3 years age group, and less common in females. Patients with mild hyponatremia had a significantly prolonged median length of stay in the PED compared to normonatremic patients (5.8 h vs. 4.4 h, p < 0.001). Moreover, they showed significantly higher rates of ward admission (51.1% vs. 35.6%, p < 0.001), vasopressor administration (1.1% vs. 0.6%, p = 0.014), PICU admission (2.4% vs. 1.0%, p < 0.001), and mortality (1.5% vs. 0.3%, p < 0.001). Compared with the normonatremia group, the odds ratios (95% CI) for ward admission, vasopressor administration, PICU admission, and mortality in the mild hyponatremia group were 1.90 (1.71-2.10), 1.91 (1.17-3.13), 2.62 (1.86-3.68), and 5.56 (3.51-8.80), respectively. Furthermore, our findings demonstrate a notable upward trend in adverse outcomes, including vasopressor administration, PICU admission, and mortality, from mild hyponatremia to severe hyponatremia. In conclusion, we found that adverse outcomes increase with the severity of hyponatremia in children presenting to the PED, highlighting the importance of immediate intervention alongside the identification of the underlying cause.

Zobel MJ, Stewart L. Hyponatremia is associated with more severe biliary disease. World J Gastrointest Surg 2020; 12:45-54. [PMID: 32128028 PMCID: PMC7044107 DOI: 10.4240/wjgs.v12.i2.45] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2019] [Revised: 11/04/2019] [Accepted: 12/15/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Sodium level is an important clinical predictor of complex biliary disease. Hyponatremia has been observed in conjunction with biliary disease, however the nature of this association remains unclear.
AIM To investigate the association between serum sodium and severe biliary disease.
METHODS Of 920 patients with gallstone disease treated at the SFVA Hospital from 1989-2019 were studied. We conducted multivariate analyses of correlation between sodium level and biliary disease severity, the presence/location of biliary bacteria, and other factors. Minimum sodium level pre-intervention was collected. Gallstones, bile, and blood (as relevant) were cultured. Illness severity was characterized: (1) None (no infectious manifestations); (2) Systemic inflammatory response syndrome; (3) Severe illness (gangrenous cholecystitis, cholangitis, necrotizing pancreatitis); and (4) Multiple organ dysfunction syndrome (bacteremia, hypotension, organ failure). Comorbidity was defined using the Charlson Comorbidity Index (CCI).
RESULTS Decreased sodium level significantly correlated with worsening illness severity, ascending bacterial infection, gangrenous changes, elevated CCI score, increasing age, male sex, and glucose. On multivariate analysis, all factors, except age, gender and glucose, independently correlated with sodium level and factors were additive.
CONCLUSION This unique study is the first to explore, with such granularity, the relationship between biliary disease and sodium. No prior studies have examined specific culture and clinical data. It illustrates an inverse, independent correlation between illness severity and sodium. Culture data demonstrate that sodium decreases as infection ascends from gallstone colonization to bactibilia to bacteremia. Patient comorbidity and gangrenous changes also independently correlate with sodium on multivariate analysis. Sodium level is an important clinical indicator of disease severity for patients with biliary disease.

Abstract
Background and Objectives Both hyponatremia and acute kidney injury (AKI) are common and harmful in hospitalized patients. However, their combined effects on patient mortality have been little studied. Methods We retrospectively enrolled 19191 adult patients who were admitted for 1 year. Pre-existing hyponatremia was defined as a serum sodium level < 135 mmol/L on the first measurement of their admission. AKI was defined as a rise in serum creatinine by ≥ 26.5 μmol/L or ≥ 1.5 times of the baseline value of creatinine during the hospital stay. Results The prevalence of pre-existing hyponatremia was 8.2%. During a median 6.0 days of hospital stay, the incidence rates of AKI and in-hospital patient mortality were 5.1% and 0.9%, respectively. Pre-existing hyponatremia independently predicted AKI development and in-hospital mortality (adjusted hazard ratio [HR] 1.300, P = 0.004; HR 2.481, P = 0.002, respectively). Pre-existing hyponatremia and subsequent development of AKI increased in-hospital mortality by 85 times, compared to the patients with normonatremia and no AKI. In subgroup analysis, the AKI group showed higher rates of de novo hypernatremia than the non-AKI group during the admission. De novo hypernatremia, which might be associated with over-correction of hyponatremia, increased in-hospital mortality (HR 3.297, P <0.001), and patients with AKI showed significantly higher rates of de novo hypernatremia than patients without AKI (16.2% vs. 1.4%, P < 0.001, respectively). Conclusion Pre-existing hyponatremia may be associated with the development of AKI in hospitalized patients, and both hyponatremia and hospital-acquired AKI could have a detrimental effect on short term patient mortality, which might be related to the inappropriate correction of hyponatremia in AKI patients.

Abstract
BACKGROUND Hyponatraemia occurs during bronchiolitis, sometimes with neurological manifestations. The prevalence of the latter differs widely and little is known about the time of occurrence and associated factors. This study was undertaken to investigate these complications. METHODS This was a retrospective observational chart review of a cohort of 233 infants under 2 years of age admitted with bronchiolitis to a teaching hospital in the United Arab Emirates. RESULTS Hyponatraemia (serum sodium <135 mmol/L) occurred in 105 infants (45%, 95% CI 38-51). Hyponatraemia was present on admission in 84 infants (80%) with 90% of cases occurring within 6 days of the onset of illness. It was mild (130-135) in 100 infants (95%) and severe (<130) in five (5%). It was not significantly associated with age, duration of illness before admission, viral aetiology, white cell count or serum C-reactive protein concentrations, or the volume of administered intravenous fluid or use of 0.18% sodium chloride (NaCl). Neurological manifestations occurred in a 29-day-old child with a serum sodium level of 123 mmol/L while receiving two-thirds intravenous maintenance fluids (0.18% NaCl). His developmental milestones remained normal on follow-up to the age of 5 years. CONCLUSION Hyponatraemia is common in infants with bronchiolitis and occurs in the majority within 6 days of onset of symptoms. There was a significant association between the presence of fever (>38°C) on admission and the duration of hospitalisation.

Abstract
Timely diagnosis of hyponatremia is important for preventing potential morbidity and mortality as it is often an indicator of underlying disease. The most common cause of eurvolemic hyponatremia is the syndrome of inappropriate antidiuretic hormone (SIADH) secretion. Recent studies have demonstrated that proinflammatory cytokines such as interleukin (IL) 1β and IL-6 are involved in the development of hyponatremia, a condition that is associated with severe inflammation and is related to antidiuretic hormone (ADH) secretion. Serum sodium levels in hyponatremia are inversely correlated with the percentage of neutrophils, C-reactive protein, and N-terminal-pro brain type natriuretic peptide. Additionally, elevated levels of serum IL-6 and IL-1β are found in inflammatory diseases, and their levels are higher in patients with hyponatremia. Because it is significantly correlated with the degree of inflammation in children, hyponatremia could be used as a diagnostic marker of pediatric inflammatory diseases. Based on available evidence, we hypothesize that hyponatremia may be associated with inflammatory diseases in general. Understanding the mechanisms responsible for augmented ADH secretion during inflammation, monitoring patient sodium levels, and selecting the appropriate intravenous fluid treatment are important components that may lower the morbidity and mortality of patients in a critical condition.

Abstract
Macrophage activation syndrome, a life-threatening complication of rheumatic disorders, is accompanied by the overproduction of cytokines. We describe a girl with macrophage activation syndrome complicating systemic-onset juvenile arthritis who developed hyponatremia, hypophosphatemia, and hypouricemia associated with a high level of serum tumor necrosis factor alpha. Renal proximal tubule dysfunction was considered to be the cause, which may be attributable to tumor necrosis factor alpha.

Abstract
In a retrospective analysis we evaluated the occurrence of infections in 59 children with acute lymphoblastic leukemia (ALL) during the entire duration of their anticancer chemotherapy. We recorded a total of 245 infection episodes, 118 (50%) being during neutropenia and 119 (50%) during nonneutropenia. The infections most commonly detected during neutropenia were fevers of undetermined origin (36%), clinically or microbiologically defined focal infections (33%), and bacteremias (28%). During nonneutropenia, upper respiratory tract infections (55%) were the most common. Patients needed hospitalization for infections for a total of 1951 days (i.e., a mean of 33 days per patient) and the mean number of infection episodes was 4.2 per patient. Recurrent fever developed in 21% of the children with bacteremia. Mortality caused by bacteremias was 10%. Infections during the chemotherapy of ALL were a significant cause of morbidity in children, but mortality was low.

Abstract
OBJECTIVE Interleukin-6 (IL6), tumor necrosis factor-alpha (TNF-alpha) and interferon-gamma (IFN-gamma) are important mediators of the inflammatory response in human infection. The aim of this study was to determine the relationship between serum levels of IL6, TNF-alpha, IFN-gamma and CRP in febrile children with malignant disease, and relate these levels to aetiology of fever, presence of neutropenia and the effect of untreated malignancy. METHODS 110 febrile episodes in 70 children with malignant disease were included. Cytokine analyses were performed with sensitive immunoradiometric methods using double monoclonal antibodies. RESULTS IL6 had a sensitivity of 74% in detecting sepsis in children with fever and malignant disease. This sensitivity was not influenced by the presence of neutropenia or newly diagnosed malignancy. A positive correlation between IL6 and the CRP levels on the following day was observed (r = .53). TNF-alpha was elevated in 22% of the episodes and mean levels were significantly higher in untreated malignancy but lower in neutropenic patients. IFN-gamma was elevated in 18% of cases and correlated strongly with mean TNF-alpha levels. CONCLUSIONS IL6 is a sensitive and early predictor of bacterial infection in both neutropenic and non-neutropenic febrile children with malignancy. It is more sensitive than CRP in detecting sepsis, but the predictive value is too low to allow IL6 levels to influence initial treatment decisions in patients with granulocytopenia. TNF-alpha production seems to be impaired in neutropenic children and serum TNF-alpha cannot be employed as an indicator of bacterial infection.

Abstract
At the Children's Hospital, University of Helsinki, Finland, bone marrow transplantations have been performed since 1974. Between 1974 and 1992, 62 children received allogeneic bone marrow grafts. Median patient age was 9.3 years. Thirty-two patients had ALL, 13 AML and 11 had severe aplastic anemia (SAA). Graft failure occurred in 4 of the 62 patients. The overall long-term survival rate was 47%. Relapse of leukemia was the most common cause of death, especially in patients with ALL transplanted in second or later remission. Deaths during the first 2 months after transplant have decreased with time. In a small country such as Finland, it is important to centralize the experience of allogeneic BMTs, particularly for pediatric patients.

Abstract
BACKGROUND Infections cause significant morbidity in children with acute lymphoblastic leukemia (ALL). The incidence of viral infections commonly occurring in children with ALL receiving chemotherapy was compared with viral infections in control children and the spread of infections in families was traced. METHODS Fifteen families of children with ALL receiving chemotherapy (62 members) and 26 matched control families (106 members) were monitored for a total of 36,197 and 36,583 days, respectively, from November/ 1987 to December/1989 for the occurrence of infections. RESULTS The children with ALL had more infections than their control counterparts (P < 0.01) with respiratory infections the most common in both groups. Viral etiology was verified for 47 episodes [5.2/1000 days at risk, 95% confidence interval (CI) 3.9-7.0] in the children with ALL and 22 (2.4/1000 days at risk, 95% CI 1.5-3.7) in the control subjects (P < 0.01 for the difference). Parainfluenza viruses, enteroviruses, and adenoviruses were the most common agents in both groups. The infections of the other members of the patients' families were similar to those of their controls. The children most commonly fell ill first, and although children with ALL had more infections, they did not appear to spread the infections to their family members. CONCLUSIONS The children with ALL had more infections than their controls, but they managed to recover well from viral infections caused by common respiratory viruses. The children with ALL did not change the spread of infections among family members.

Abstract
The hospital files of 410 patients with hematological malignancy treated at our clinic between 1977 and 1990 were reviewed to determine the importance of infections as a cause of death. The total number of infections was 203 (49.5%). A microbiologically documented infection was detected in 27.3%, a clinically documented infection in 9.5% and a possible infection in 12.7% of the patients. Gram-positive bacteria were responsible for 25.9%, gram-negative bacteria for 31.3%, anaerobic bacteria for 2.7%, viruses for 4.5% and fungi for 25.9% of the microbiologically documented infections. Of 29 systemic fungal infections only 2 were diagnosed before the patients died. The remaining diagnoses rested on autopsy findings. Empiric antifungal therapy was introduced in 1983; still, 74.2% of systemic fungal infections in 1977-1990 were detected after 1982. Patients with a verified infection had statistically significantly higher CRP concentrations than patients who died of other causes (152 mg/l vs. 117.5 mg/l, p = 0.018). We conclude that infection is a significant cause of death in patients with these diseases. The number of systemic fungal infections is increasing, despite the widespread use of antifungal medication and thus better diagnostic methods and more effective treatment are needed.
