- Acute petrified myocardium associated with meningococcal sepsis in childhood-onset systemic lupus erythematous: a fatal case(2019) SANTOS, Ana Carolina Etrusco Zaroni; LUGLIO, Michele; DELGADO, Artur Figueiredo; SCHUWARTZ, Constance Dell Santo Vieira; MARQUES, Heloisa Helena Sousa; VALOES, Clarissa Carvalho de Miranda; DOMINGUEZ, Maria Andreina Cabrera; CARVALHO, Werther Brunow de; SILVA, Clovis Artur; DUARTE-NETO, Amaro NunesAcute petrified myocardium associated with septic shock, diagnosed by autopsy has rarely been described. A 15-year-old adolescent male was diagnosed with childhood-onset systemic lupus erythematosus. One year later, he was hospitalized with fever, myalgia, headache, arthritis, vomiting, dyspnea and was diagnosed with sepsis secondary to bronchopneumonia and meningitis. Blood culture identified Neisseria meningitidis serogroup Y. Despite antibiotics and intensive therapeutic measures, he died after 29 days of hospitalization. The autopsy revealed necrotic cardiomyocytes with dystrophic calcification and interstitial fibrosis.

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.
- Effects of serum sodium and chloride levels in the outcome of critically ill pediatric patients in the post-operative period of liver transplantation(2023) LUGLIO, Michele; CARVALHO, Werther B. de; TANNURI, Uenis; TANNURI, Ana Cristina A.; MATSURA, Rodrigo Hideki; FRANCA, Gardenia Morais; DELGADO, Artur F.BackgroundSodium and chloride disturbances have attracted increasing attention in recent years. Many pathophysiological effects are associated with hyperchloremia, including reduction in mean arterial pressure and acute renal disease. Pediatric patients undergoing liver transplantation are at risk of developing various electrolyte and biochemical abnormalities, with an impact on their postoperative outcomes.ObjectiveTo analyze the impacts of serum sodium and chloride levels on prognosis of Pediatric Liver Transplant receptors.MethodsThis was a retrospective analytical observational study performed in a single transplant reference center in Sao Paulo, Brazil. Included patients were pediatric patients who underwent liver transplantation between January 2015 and July 2019. Statistical regression analysis and General Estimating Equations analysis were performed to evaluate the impacts of sodium and chloride disturbances on the development of acute renal failure and mortality.ResultsA total of 143 patients were included in this study. The main diagnosis was Biliary Atresia (62.9%). Twenty-seven patients died (18.9%), and graft dysfunction was the main cause of death (29.6%). The only variable individually associated with 28-days mortality was PIM-3 score (HR 1.59, CI 95% 1.165-2.177, p = 0.004). Forty-one patients (28.6%) developed moderate or severe AKI. PIM-3 score (OR 3.052, 95% CI 1.56-5.97, p = 0.001), hypernatremia (OR 3.49, 95% CI 1.32-9.23, p = 0.012), and hyponatremia (OR 4.24, 95% CI 1.52-11.85, p = 0.006) were independently associated with the development of moderate/severe AKI.ConclusionsIn pediatric patients after liver transplantation, PIM-3 score, and abnormal serum sodium levels were correlated with AKI development.

- COVID-19 and Liver Damage: Narrative Review and Proposed Clinical Protocol for Critically ill Pediatric Patients(2020) LUGLIO, Michele; TANNURI, Uenis; CARVALHO, Werther Brunow de; BASTOS, Karina Lucio de Medeiros; RODRIGUEZ, Isadora Souza; JOHNSTON, Cintia; DELGADO, Artur FigueiredoSARS-CoV-2 shares nearly 80% of its' genomic sequence with SARS-CoV and MERS-CoV, both viruses known to cause respiratory symptoms and liver impairment. The emergence of pediatric cases of multisystem inflammatory syndrome related to the SARS-CoV-2 infection (PIM-TS) has raised concerns over the issue of hepatic damage and liver enzyme elevation in the critically ill pediatric population with COVID-19. Some retrospective cohorts and case series have shown various degrees of ALT/AST elevation in SARS-CoV-2 infections. A limited number of liver histopathological studies are available that show focal hepatic periportal necrosis. This liver damage was associated with higher levels of inflammatory markers, C-reactive protein (CRP), and pro-calcitonin. Proposed pathophysiological mechanisms include an uncontrolled exacerbated inflammatory response, drug-induced liver injury, direct viral infection and damage to cholangiocytes, hypoxic-ischemic lesions, and micro-thrombosis in the liver. Based on the physiopathological characteristics described, our group proposes a clinical protocol for the surveillance, evaluation, management, and follow-up of critically ill pediatric COVID-19 patients with liver damage.

- Opioid tapering and weaning protocols in pediatric critical care units: a systematic review(2018) BICHAFF, Pedro; SETANI, Karina T.; MOTTA, Emiliana H. G.; DELGADO, Artur F.; CARVALHO, Werther B.; LUGLIO, MicheleOBJECTIVE: Opioid abstinence syndrome is common in the pediatric intensive care environment because sedation is often needed during the children's treatment. There is no specific guideline regarding the management of these patients; and lately, methadone is an important drug for the prevention of abstinence symptoms during the weaning of opioids. This study gathers the available research to establish the initial dose of methadone, the rate of taper and tools to recognize this syndrome and act promptly. METHODS: A systematic review was made from data of four different databases. Forty-nine articles of observational and experimental studies were selected based on the inclusion criteria (critical pediatric patients in acute use of opioids) and exclusion criteria (previous chronic use of opioids, other medications). The data regarding specific themes were separated in sections: initial dose of methadone, use of protocols in clinical practice, abstinence scales and adjuvant drugs. RESULTS: The articles showed a great heterogeneity of ways to calculate the initial dose of methadone. The pediatric intensive care units of the study had different weaning protocols, with a lower incidence of abstinence when a pre-defined sequence of tapering was used. The Withdrawal Assessment Tool - 1 was the most used scale for tapering the opioids, with good sensitivity and specificity for signs and symptoms. CONCLUSION: There is still little evidence of other medications that can help prevent the abstinence syndrome of opioids. This study tries to promote a better practice during opioid weaning.
- Importance of the use of protocols for the management of analgesia and sedation in pediatric intensive care unit(2016) MOTTA, Emiliana; LUGLIO, Michele; DELGADO, Artur Figueiredo; CARVALHO, Werther Brunow DeIntroduction: Analgesia and sedation are essential elements in patient care in the intensive care unit (ICU), in order to promote the control of pain, anxiety and agitation, prevent the loss of devices, accidental extubation, and improve the synchrony of the patient with mechanical ventilation. However, excess of these medications leads to rise in morbidity and mortality. The ideal management will depend on the adoption of clinical and pharmacological measures, guided by scales and protocols. Objective: Literature review on the main aspects of analgesia and sedation, abstinence syndrome, and delirium in the pediatric intensive care unit, in order to show the importance of the use of protocols on the management of critically ill patients. Method: Articles published in the past 16 years on PubMed, Lilacs, and the Cochrane Library, with the terms analgesia, sedation, abstinence syndrome, mild sedation, daily interruption, and intensive care unit. Results: Seventy-six articles considered relevant were selected to describe the importance of using a protocol of sedation and analgesia. They recommended mild sedation and the use of assessment scales, daily interruptions, and spontaneous breathing test. These measures shorten the time of mechanical ventilation, as well as length of hospital stay, and help to control abstinence and delirium, without increasing the risk of morbidity and morbidity. Conclusion: Despite the lack of controlled and randomized clinical trials in the pediatric setting, the use of protocols, optimizing mild sedation, leads to decreased morbidity.
