- Lymphocyte count as a sign of immunoparalysis and its correlation with nutritional status in pediatric intensive care patients with sepsis: A pilot study(2016) MANZOLI, Talita Freitas; DELGADO, Artur Figueiredo; TROSTER, Eduardo Juan; CARVALHO, Werther Brunow de; ANTUNES, Ana Caroline Barreto; MARQUES, Desiree Mayara; ZAMBERLAN, PatriciaOBJECTIVES: Developing malnutrition during hospitalization is well recognized worldwide, and children are at a relatively higher risk for malnutrition than adults. Malnutrition can lead to immune dysfunction, which is associated with a higher mortality rate due to sepsis, the most frequent cause of death in pediatric intensive care units (PICUs). The aim of this study was to investigate whether malnourished patients are more likely to have relative or absolute lymphopenia and, consequently, worse prognoses. METHODS: We enrolled 14 consecutive patients with sepsis whose legal representatives provided written informed consent. Patients were classified as normal or malnourished based on anthropometric measurements. As an additional evaluation of nutritional status, serum albumin and zinc were measured on the 1 st and 7 th days of hospitalization. Lymphocyte count was also measured on the 1 st and 7 th days. Clinicaltrials. gov: NCT02698683. RESULTS: Malnutrition prevalence rates were 33.3% and 42.8% based on weight and height, respectively. Laboratory analyses revealed a reduction of serum albumin in 100% of patients and reduction of zinc in 93.3% of patients. A total of 35% of patients had fewer than 500 lymphocytes/mm(3) on their first day in the PICU. Lymphocyte counts and zinc concentrations significantly increased during hospitalization. CONCLUSIONS: Nutritional evaluations, including anthropometric measurements, were not correlated with lymphocyte counts. Lymphocyte counts concomitantly increased with zinc levels, suggesting that micronutrient supplementation benefits patients with sepsis.

Design: Survey with a questionnaire sent to Latin American Society of Pediatric Intensive Care members. Setting: PICUs of participant hospitals. Patients: Critically ill children between 1 month and 18 years old. Interventions: None. Measurements and Main Results: Forty-seven surveys from 17 countries were analyzed. Sixty-seven percent of PICUs were from university-affiliated hospitals, with a median of 380 admissions/yr. Sixty-eight percent and 48.9% had a nutritional support team and nutritional support protocol, respectively. Seventy-five percent completed nutritional evaluations, with 34.2% at admission. PICUs with high-volume admissions were likely to have a nutritional support team (p < 0.005), and university-affiliated hospitals showed a trend of having a nutritional support team (p = 0.056). Measured, estimated, and ideal weights were used in 75%, 14.6%, and 10.4%, respectively. Energy requirements were calculated using Holliday & Segar and Schofield equations in 90% of the PICUs; 43% used correction factors. Only three PICUs had indirect calorimetry. At day 3 of initiation of nutritional support, 57.3% of PICUs provided at least 50% of the calculated energy requirement, and 91.5% at day 5. Protein needs were estimated according to American Society for Parenteral and Enteral Nutrition and European Society for Clinical Nutrition and Metabolism/European Society for Paediatric Gastroenterology Hepatology and Nutrition guidelines in 55.3% and 40.4%, respectively. Enteral nutrition was the preferred feeding method, initiated in 97.7% at 48 hours. The feeding route was gastric (82.9%), by bolus (42.5%) or continuous (57.4%). Monitoring methods included gastric residual measurement in 55.3%. Enteral nutrition was discontinued in 82.8% when gastric residual was 50% of the volume. Prokinetics were used in 68%. More than half of PICUs used parenteral nutrition, with 95.8% of them within 72 hours. Parenteral nutrition was administered by central vein in 93.6%. Undernourished children received parenteral nutrition sooner, whether or not enteral nutrition intolerance was present. When enteral nutrition was not tolerated beyond 72 hours, parenteral nutrition was started in 57.4%. Parenteral nutrition was initiated when enteral nutrition delivered less than 50% in 97%. Conclusions: Nutritional practices are heterogeneous in Latin American PICUs, but the majority use nutritional support strategies consistent with international guidelines.
- Changes in lipid metabolism in pediatric patients with severe sepsis and septic shock(2018) BERMUDES, Ana Carolina G.; CARVALHO, Werther B. de; ZAMBERLAN, Patricia; MURAMOTO, Giovana; MARANHAO, Raul C.; DELGADO, Artur F.Objectives: Limited knowledge exists regarding the lipid profiles of critically ill pediatric patients with systemic inflammatory response syndrome. The aim of this study was to evaluate the relationship between the intensity of the inflammatory response and changes in the lipid profiles of critically ill pediatric patients admitted to a pediatric intensive care unit (PICU) with severe sepsis/septic shock. Methods: This was a prospective and observational study at a 15-bed PICU at a public university hospital. We analyzed the lipid profiles of 40 patients with severe sepsis/septic shock admitted to the PICU on the first and seventh days of hospitalization. C-reactive protein was used as a marker for systemic inflammation. Forty-two pediatric patients seen in the emergency department and without systemic inflammatory response syndrome were used to provide control values. Results: On day 1 of admission to the PICU, the patients had significantly lower levels of total cholesterol (TC), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) as well as higher concentrations of triacylglycerols compared with the control group. There was a significant increase in the TC, HDL, LDL, and apolipoprotein levels from day 1 to day 7 of the study. Conclusions: During severe sepsis/septic shock, we found lower serum levels of lipoproteins and apolipoproteins, and these were negatively correlated with C-reactive protein. As the inflammatory response improved, the levels of TC, HDL, LDL, and apolipoproteins increased, suggesting a direct relationship between changes in the lipid profiles and inflammation.
- Malnutrition and Nutrition Support in Latin American PICUs: The Nutrition in PICU (NutriPIC) Study(2023) CAMPOS-MINO, Santiago; FIGUEIREDO-DELGADO, Artur; ZARATE, Patricia; ZAMBERLAN, Patricia; MUNOZ-BENAVIDES, Eliana; COSS-BU, Jorge A.OBJECTIVES: To characterize the nutritional status of children admitted to Latin American (LA) PICUs and to describe the adequacy of nutrition support in reference to contemporary international recommendations. DESIGN: The Nutrition in PICU (NutriPIC) study was a combined point-prevalence study of malnutrition carried out on 1 day in 2021 (Monday 8 November) and a retrospective cohort study of adequacy of nutritional support in the week preceding. SETTING: Four-one PICUs in 13 LA countries. PATIENTS: Patients already admitted to the PICU of 1 month to 18 years old on the study day were included in the point-prevalence study. For the retrospective arm, we included patients receiving nutritional support on the study day and with a PICU length of stay (LOS) greater than or equal to 72 hours. Exclusion criteria were being a neonate, conditions that precluded accurate anthropometric measurements, and PICU LOS greater than 14 days. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 316 patients screened, 5 did not meet age criteria. There were 191 of 311 patients who were included in the point-prevalence study and underwent anthropometric evaluation. Underweight and length for age less than -2 z scores were present in 42 of 88 children (47.7%) and 41 of 88 children (46.6%) less than 24 months old, and 14 of 103 (13.6%) and (23/103) 22.3% of 103 children greater than or equal to 24 months, respectively. Evidence of obesity (body mass index > 2 z score) was present in 7 of 88 children (5.7%) less than 24 months old and 13 of 103 children (12.6%) greater than or equal to 24 months. In the 115 of 311 patients meeting criteria for the retrospective arm, a total of 98 patients reported complete nutritional data. The 7-day median (interquartile range) adequacy for delivered versus recommended enteral energy and protein requirement was 114% (75, 154) and 99% (60, 133), respectively. CONCLUSIONS: The NutriPIC study found that in 2021 malnutrition was highly prevalent especially in PICU admissions of less than 24 months old. Retrospectively, the 7-day median nutritional support appears to meet both energy and protein requirements.
- What Is the Purpose of Using an Old Biomarker in the Prognosis in PICUs?(2016) ZAMBERLAN, Patricia; DELGADO, Artur Figueiredo; CARVALHO, Werther Brunow de
- Body composition in pediatric patients(2023) ZAMBERLAN, Patricia; MAZZONI, Beatriz P.; BONFIM, Maria A. C.; VIEIRA, Rafaela R.; TUMAS, Rosana; DELGADO, Artur F.Undernutrition is highly prevalent in children who are critically ill and is associated with increased morbidity and mortality, including a higher risk of infection due to transitory immunological disorders, inadequate wound healing, reduced gut function, longer dependency on mechanical ventilation, and longer hospital stays compared with eutrophic children who are critically ill. Nutrition care studies have proposed that early interventions targeting nutrition assessment can prevent or minimize the complications of undernutrition. Stress promotes an acute inflammatory response mediated by cytokines, resulting in increased basal metabolism and nitrogen excretion and leading to muscle loss and changes in body composition. Therefore, the inclusion of body composition assessment is important in the evaluation of these patients because, in addition to the nutrition aspect, body composition seems to predict clinical prognosis. Several techniques can be used to assess body composition, such as arm measurements, calf circumference, grip strength, bioelectrical impedance analysis, and imaging examinations, including computed tomography and dual-energy x-ray absorptiometry. This review of available evidence suggests that arm measurements seem to be well-established in assessing body composition in children who are critically ill, and that bioelectrical impedance analysis with phase angle, handgrip strength, calf circumference and ultrasound seem to be promising in this evaluation. However, further robust studies based on scientific evidence are necessary.
- Increased nutrition risk at admission is associated with longer hospitalization in children and adolescents with COVID-19(2022) ZAMBERLAN, Patricia; CARLOTTI, Ana Paula de Carvalho Panzeri; VIANI, Karina Helena Canton; RODRIGUEZ, Isadora Souza; SIMAS, Josiane de Carvalho; SILVERIO, Ariadne Beatriz; VOLPON, Leila Costa; CARVALHO, Werther Brunow de; DELGADO, Artur FigueiredoBackground We investigated the association of nutritional risk and inflammatory marker level with length of stay (LOS) in children and adolescents hospitalized for COVID-19 infection in two pediatric teaching hospitals in a developing country. Methods This was a cross-sectional analytical retrospective study performed in two pediatric hospitals. We included the data from all children and adolescents who were hospitalized with a SARS-CoV-2 infection between March and December 2020. Demographic, anthropometric, clinical, and laboratory data were extracted from electronic medical records. Nutritional risk was assessed according to the STRONGkids tool within 24 hours of admission and was categorized into two levels: >= 4 (high risk) and <4 (moderate or low risk). Means or medians were compared between nutritional risk groups using the t test and Mann-Whitney U test, respectively. The association of nutritional risk and inflammatory markers with LOS was estimated using the Kaplan-Meier method and log-rank test. Cox proportional-hazard and linear regression models were performed, and adjusted for sex, age, and respiratory symptoms. Results From a total of 73 patients, 20 (27.4%) had a STRONGkids score >= 4 at admission, which was associated with a longer LOS even after adjusting (beta = 12.30; 1.74-22.9 95% CI; P = 0.023). The same association was observed between LOS and all laboratory markers except for D-dimer. Conclusion Among children and adolescents with COVID-19, a STRONGkids score >= 4 at admission, lower values of albumin, lymphocytes, and hemoglobin, and higher CRP values were associated with longer LOS.
- Bioelectrical Impedance Phase Angle and Morbidity and Mortality in Critically Ill Children(2019) ZAMBERLAN, Patricia; FEFERBAUM, Rubens; DORIA FILHO, Ulysses; CARVALHO, Werther Brunow de; DELGADO, Artur FigueiredoBackgroundNutrition markers may be useful for diagnosis and monitoring and, also, as additional indicators of estimating death risk. We tested the association of body composition indicators (mid-upper arm circumference and phase angle) with pediatric intensive care unit (PICU) length of stay and mortality in critically ill pediatric patients. MethodsData from children aged 2 months-18 years were collected, and bioelectrical impedance was performed to obtain phase angle. Severity was evaluated by scoring the Pediatric Index of Mortality. Descriptive statistics were reported for nominal variables. Receiver operating characteristic curve was used to analyze the association of phase angle with 30-day mortality and to find the best cutoff. Survival probabilities and PICU length of stay were estimated using the Kaplan-Meier method. ResultsWe evaluated 247 children with a median age of 4.8 years whose main cause of admission was sepsis. Survival curves showed higher survival in patients with phase angle >2.8 degrees compared with patients with phase angle 2.8 degrees (P<.0001). Kaplan-Meier time-to-event analysis showed that children with lower phase angle values were more likely to remain in the PICU (hazard ratio, 1.84; P=.003). Lower survival was also observed in patients who presented mid-upper arm circumference values 5th percentile (P<.03). ConclusionsMid-upper arm circumference and phase angle were associated with mortality and morbidity in critically ill children, suggesting that these parameters may be useful not only for nutrition diagnosis and monitoring, but also as an additional indicator in estimating prognosis.
