Does an episode of diabetic ketoacidosis affect thyroid function tests in pediatric patients?

OBJECTIVES: The aim of our study was to investigate the changes in thyroid hormone levels during and after acute metabolic disorder in patients with diabetic ketoacidosis (DKA). METHODS: Eighty five patients diagnosed with DKA were included in the study. Patients with control thyroid function test (TFT) values at admission (the first blood sample) and 1 month later were included in the study. Thyroid function tests obtained during diabetic ketoacidosis and at the first month follow-up were compared. Euthyroidism and euthyroid sick syndrome were defined and grouped according to current guidelines. The mild and moderate groups, according to DKA classification, were combined and compared with the severe group. RESULTS: A significant increase was observed between the first admission and the control TFT values 1 month later. However, there was no significant difference found in TFT between mild/moderate and severe groups taken at the time of DKA. Difference between two groups, euthyroid sick syndrome and euthyroid, was examined and the result that was different from the literature was the difference between TSH levels. We found that low FT4 levels were associated with higher HgbA1c, although the correlation was weak. CONCLUSIONS: Thyroid hormone levels may not reflect a thyroid disease during severe DKA attack. Therefore, it is unnecessary to check thyroid function tests.

The effect of myocardial dysfunction on mortality in children with septic shock: a prospective observational study.

Pediatric septic shock is defined as progressive multi-organ dysfunction and cardiovascular dysfunction accompanying sepsis. Studies showing myocardial dysfunction associated with pediatric septic shock are very limited. The aim of this study was to evaluate the relationship between myocardial functions calculated by echocardiography, disease severity, and clinical outcomes in children with septic shock. This observational prospective study was conducted in a pediatric intensive care at a university-affiliated tertiary hospital. The patients diagnosed with septic shock between January 2021 and February 2022 were included in the study. The study was conducted with 56 patients. The rate of myocardial dysfunction (systolic and/or diastolic dysfunction) was 50%. Of these, 39.3% (n = 22) had systolic dysfunction, 17.9% (n = 10) had diastolic dysfunction, and 8.9% (n = 5) had both systolic and diastolic dysfunction. PRISM III score (p = 0.004), VIS (p < 0.001), lactate (p = 0.002), CK-MB (p = 0.023), troponin (p = 0.038), EF (p = 0.004) EF z-score (p = 0.003), MAPSE z-score (p = 0.049), TAPSE (p = 0.010), TAPSE z-score (p = 0.003), and mitral valve E/e ´z-score (p = 0.028) were statistically significant difference with mortality. No significant difference was found for mortality with MAPSE (p = 0.090), mitral valve E/A (p = 0.624), and mitral valve E/A z-score (p = 0.327). EF z-score was found to be associated with 30-day mortality (OR = 0,681, 95% CI 0,480 to 0.991, p = 0,045). We found the TAPSE z-score to be the most significant parameter with 30-day mortality (OR = 0,690, 95% CI 0,489 to 0.998, p = 0,032).  Conclusion: We found left ventricular dysfunction associated factor with mortality. TAPSE showing right ventricular dysfunction was found to be the independent risk factor most associated with mortality. What is Known: • Studies showing myocardial dysfunction associated with pediatric septic shock are limited. • Little is known about the use of echocardiography in pediatric septic shock, and there are no specific guidelines for treatment and follow-up in pediatric patients. What is New: • Characteristics, echocardiographic measurements, and outcomes were comprehensively assessed in children with septic shock. • As a result of our analysis, we found that TAPSE, which is easily measured at the bedside, is the most critical parameter in relation to mortality. • We offer recommendations for its use in the follow-up of children with septic shock.

The impact of central line bundles on the timing of catheter-associated bloodstream infections and their microbiological distribution in critically ill children.

Catheter-associated bloodstream infection, also known as CLABSI, is the most serious consequence of central venous access devices. These infections increase the risk of mortality and morbidity. The use of central line bundles in clinical settings is increasing worldwide with the purpose of lowering the risk of catheter-associated bloodstream infections. In this study, we investigated the effect of implementing a central line bundle for the prevention of CLABSIs, the distribution of pathogens, and the duration of time it took for CLABSIs to develop in patients who had subclavian-inserted central venous catheters. This research project was a cross-sectional study investigation carried out in a pediatric tertiary teaching hospital. Participants consisted of children who had been admitted to the pediatric critical care unit with subclavian catheters during a period of 13 years. We compared the prebundle period with the bundle period for CLABSI specifically focusing on the time to infection, the number of polymicrobial infections, the proportion of Candida parapsilosis, and the percentage of Coagulase-negative staphylococci (CoNS). The "prebundle period" included the period from May 2007 to May 2013, and the "bundle period" included the period from June 2013 to June 2020. Throughout the course of the study, a total of 286 cases of CLABSI were documented. Among these patients, 141 (49.3%) had CLABSIs associated with subclavian catheters. During the prebundle period, 55 CLABSIs were diagnosed in 5235 central line days, with an overall rate of 10.5 CLABSIs per 1000 central line days; after the implementation of central line bundle, 86 CLABSIs were diagnosed in 12,450 CL days, with an overall rate of 3.6 CLABSIs per 1000 CL days. This showed a statistically significantly lower rate in the bundle period (p = 0.0126). In the prebundle period, the mean time to develop CLABSI was 15 days, whereas during the bundle period, the mean time to develop CLABSI was 27.9 days, a significantly longer time to onset (p = 0.001). While the percentage of other microorganisms was not statistically different between the prebundle and bundle periods (p > 0.05), the percentage of C. parapsilosis was significantly higher in the prebundle period (p = 0.001).   Conclusion: The results of this study imply that the use of central line bundles not only reduces the incidence of CLABSI but also delays the time to which CLABSI patients acquire an infection. In addition, as a direct consequence of the CLB, the number of CLABSIs caused by gram-positive cocci did not increase, while the proportion of CLABSIs caused by C. parapsilosis decreased. What is Known: • The most significant negative consequence of central venous access devices is catheter-associated bloodstream infections. • "Care bundles" for CLABSI prevention have been reported to reduce the CLABSI rate. What is New: • Consider what would happen if the "Care bundle" failed to prevent CLABSI. • The findings of this study imply that using central line bundles not only reduces the risk of CLABSI but also extends the time it takes for patients to develop CLABSI. While the number of CLABSIs caused by gram-positive cocci did not increase as a direct result of CLB, the rate of CLABSIs caused by C. parapsilosis, which has recently become a major problem, has decreased.

Clinical Features and Management of Status Epilepticus in the Pediatric Intensive Care Unit.

OBJECTIVES: Status epilepticus (SE) is associated with significant morbidity and mortality in children. SE in the pediatric intensive care unit (PICU) are not well characterized. The aim of this study is to retrospectively investigate the clinical features and treatment of seizures in children admitted to the PICU of our hospital. METHODS: We retrospectively examined the clinical characteristics of patients aged between 1 month and 18 years who were admitted to our hospital with SE or who were diagnosed with SE after hospitalization and were followed up with continuous electroencephalographic monitoring between January 2015 and December 2019. RESULTS: A total of 88 patients with SE, 50 (56.8%) boys and 38 (43.2%) girls, were included. The median age was 24 months (interquartile range, 12-80 months). When we evaluate the continuous electroencephalographic monitoring data, 27 (30.7%) were lateralized, 20 (22.7%) were multifocal, 30 (34.1%) were generalized, and 11 (12.5%) were bilateral independent epileptic activity. Seventy nine patients (89.8%) were evaluated as convulsive status epilepticus (CSE) and 9 (10.2%) as nonconvulsive status epilepticus (NCSE). Pediatric Risk of Mortality (PRISM III) score and mortality of patients with NCSE were higher ( P = 0.004 and P = 0.046, respectively). Thirteen eight patients (43.1%) were diagnosed as SE, 38 patients (43.1%) as refractory SE, and 12 patients (13.6%) as super-refractory SE. The overall mortality rate was 10.2%. CONCLUSIONS: Status epilepticus is a neurological emergency that causes mortality and morbidity. Electroencephalographic monitoring is important for the recognition of seizures and rapid intervention. No superiority of second-line treatments or combined treatments was demonstrated in patients with SE.

Pediatric Status Epilepticus Severity Score (STEPSS): Predictive Performance of Functional Outcomes: A Prospective Single-Center Study.

Objective: To prospectively investigate the predictive value of the modified Status Epilepticus Severity Score (STESS) for pediatric use (STEPSS) regarding unfavorable outcomes in the short term. Methods: Patients diagnosed as status epilepticus in the emergency department between January 2019 and June 2021 at a tertiary center of the University of Health Sciences, Dr. Behcet Uz Children's Hospital, were included in the study. The patients were followed up in the emergency department, neurology clinic, and pediatric intensive care unit until discharge. Demographic and clinical characteristics, STEPSS, and Pediatric Overall Performance Category Scale (POPC) scores were calculated. We defined a Pediatric Overall Performance Category Scale score ≥3 as an unfavorable outcome. We compared the effect of STEPSS on unfavorable outcomes and mortality. Results: 124 children were included. The median age was 33 months (interquartile range 16.2-84.7). Seventy-two (58.1%) patients had acute symptomatic etiology. We found that the STEPSS score with the receiver operating characteristic curve (area under the curve = 0.917, P < .001) could predict unfavorable outcomes (Pediatric Overall Performance Category Scale score ≥3) in children with status epilepticus. The Youden index (0.76) showed that a STEPSS score >2 was the optimal cutoff point for an unfavorable outcome. We found STEPSS useful in predicting mortality (area under the curve = 0.853, P < .001). The Youden index (0.58) indicated that a STEPSS >2 was the optimal cutoff for mortality: sensitivity 0.90 (95% confidence interval [CI] 0.58-0.99), specificity 0.67 (95% CI 0.57-0.77), positive predictive value 0.21, negative predictive value 0.98, positive likelihood ratio 2.7, negative likelihood ratio 0.14. Conclusion: We determined that STEPSS can be predicted unfavorable outcomes and mortality. We think that STEPSS can be used as a useful clinical score with further studies and external validations.

Could lactate clearance be a marker of mortality in pediatric intensive care unit?

BACKGROUND: Hyperlactatemia is a common finding in critically ill patients and has significant prognostic implications. However, a single lactate measurement has not been correlated to mortality consistently. In this study, we aimed to correlate the clinical efficacy of lactate clearance for the prediction of mortality in pediatric intensive care unit patients. METHODS: This retrospective observational study was performed in the pediatric intensive care unit in patients with lactate level >3 mmol/lt. Initial, 6th h, and 24th h lactate levels were recorded and lactate clearance was calculated using these values (lactate level at admission - level 6 h later × 100/lactate level at admission). RESULTS: A total of 172 patients were included in the study. Forty-four out of 172 patients died. Median (IQR) lactate (mmol/L) at admission was low in those who survived in comparison to nonsurvivors 4.4 (3.1) vs. 5.75 (7.7) (p = 0.002). Clearance at 6th h was significantly lower in those who died (11.7%) than those who survived (36.7) (p = 0.001). 6th h lactate clearance level <20.7% predicted mortality with a sensitivity of 63.6% and specificity of 69.5% along with a positive predictive value of 41.8 and a negative predictive value of 84.8 (p = 0.004). Both lactate levels and lactate clearance values were significantly predictive factors for mortality (p < 0.05). Only a positive moderate correlation was found between the percentage of PRISM-IV % and 6th h lactate level. DISCUSSION: The present study revealed that lactate clearance is a simple and rapid risk-stratification tool holding to be a potential biomarker of managing the treatment efficacy of children in the pediatric intensive care unit.

A Comparative Study of Children with MIS-C between Admitted to the Pediatric Intensive Care Unit and Pediatric Ward: A One-Year Retrospective Study.

OBJECTIVES: This descriptive study aimed to compare the clinical and laboratory features of the children with the multisystem inflammatory syndrome in children (MIS-C), requiring pediatric intensive care unit (PICU), admission with the MIS-C patients who did not require PICU admission. PATIENTS AND METHODS: This study was conducted between March 2020 and February 2021 at the University of Health Sciences Dr. Behçet Uz Children's Hospital, a referral center for pediatric infectious diseases in the Aegean Region of Turkey. All hospitalized patients aged 18 years old or less with MIS-C according to the definition of the universal guidelines were included in the study. Data of the patients with the diagnosis of MIS-C were recorded and collected from the electronic medical records of the hospital. The data included demographic characteristics, presenting signs and symptoms, laboratory findings and clinical data. RESULTS: A total of 58 patients with MIS-C were included in this study. Thirty-eight (65.5%) patients were male. The median age was 6 years (2 months-16 years). The patients admitted to PICU were 15 (25.9%). The rate of pulmonary involvement was 81.3% (n = 13) in the PICU group. The median procalcitonin, C-reactive protein, erythrocyte sedimentation rate, D-Dimer and ferritin values were significantly higher in the PICU group compared to non-PICU group (p < 0.001, p = 0.02, p < 0.001, p = 0.006 and p = 0.031). CONCLUSIONS: Besides the depressing cardiac functions reported before, the pulmonary involvement and signs of shock are important factors for PICU admission in children with MIS-C.

The Effect of COVID-19 Outbreak on the Mental Status of Health Care Professionals in the Pediatric Intensive Care Unit.

BACKGROUND: Coronavirus disease 2019 (COVID-19) may affect the mental status of health care professionals. The purpose of our study is to evaluate the mental health effects of the COVID-19 epidemic on health care professionals in the pediatric intensive care units (PICUs). SUBJECTS AND METHODS: Our study was conducted prospectively between 01.04.20 and 10.04.20. The created questionnaire was applied to health care professionals through online platforms. Thus it was involved in 5 different institutions that participated from different regions of Turkey. With the questionnaire, we applied; the participants' age, gender, the general status of contamination and the level of COVID-19 knowledge were questioned. Besides; Beck Anxiety Scale, Acute Stress Scale (PCL-5), STAI-1 and STAI-2 (State and Trait Anxiety Inventory 1-2) scales were used to determine the anxiety levels. RESULTS: A survey of 210 participants, 86 (41%) doctors, 124 (59%) nurses, were included in our study. When we evaluate the Beck anxiety levels, the majority of the participants (44%) were normal, while about one third had mild anxiety. When we evaluated the acute stress scale, all participants had a certain amount of stress levels. The majority (80 people each (38%)) experienced mild and moderate acute stress. Being female and having chronic disease poses a high risk for anxiety (OR, 0.330; 95% CI, 0.087-1.250, p<0.05 and OR, 0.246; 95% CI, 0.068-1.116, p<0.05), preoccupation (OR, 0.603; 95% CI 0.261-1.395, p<0.05 and OR, 0.433; 95% CI, 0.122-1.538, p<0.05) and acute stress (OR, 0.294; 95% CI, 0.033-2.649, p<0.05 and OR, 0.317; 95% CI 0.060-1.679, p<0.05). Professional definition, marital status and having a child do not pose any risk factors. CONCLUSION: Our study has shown that the COVID-19 outbreak affects the mental status of health care professionals working at PICU at various levels.

Association of Celiac Disease With Idiopathic Pulmonary Hemosiderosis; Lane Hamilton Syndrome.

INTRODUCTION: Idiopathic Pulmonary Hemosiderosis (IPH) is a rare cause of alveolar hemorrhage, which is seen primarily in childhood. Celiac disease is defined as a chronic, immune-mediated enteropathy of the small intestine, caused by exposure to dietary gluten in genetically pre-disposed individuals. Association of IPH and celiac disease is known as Lane Hamilton syndrome. There are limited number of case reports of this syndrome in literature. CASE PRESENTATION: Although there were no growth and developmental delay and gastrointestinal symptoms like chronic diarrhea, chronic constipation, vomiting, abdominal bloating and pain in the two patients with IPH, they were diagnosed with Lane Hamilton Syndrome. After initiation of gluten-free diet, their IPH symptoms disappeared and hemoglobin levels were observed to return to normal. CONCLUSIONS: Even if there were no gastrointestinal symptoms in a patient with IPH, celiac disease should be investigated. These patients may benefit from gluten free diet and IPH symptoms may disappear.
