Characterization and prognostic factors of children with sepsis in a high complexity hospital. / Caracterización y factores pronósticos de niños con sepsis en un hospital de alta complejidad.

OBJECTIVE: To describe the clinical and laboratory characteristics of patients with sepsis admitted to a high-complexity healthcare center in Latin America. PATIENTS AND METHOD: Descriptive observational study. Patients between one month to 17 years of age with sepsis diagnosis were included. Studied variables included demographics, clinical and laboratory characteristics, and treatment administered, determining predictors of mortality. A descriptive analysis was performed using the Chi-square or Fisher test. RESULTS: 186 patients were included and 72% of them had comorbidities. Respiratory disease was the most frequent source of sepsis (29%), followed by gastrointestinal infection (11%) and catheter-related bacteremia (11%). 60% of patients had at least one organ dysfunction, the most frequent being respiratory dysfunction (70%). 60% of the patients presented multiple organ dysfunction syndrome (MODS). Blood cultures showed a positive result in 37% of cases. The two most common first-hour interventions included IV resuscitation fluids (67%) and antibiotics (36%). Vasopressor support and mechanical ventilation were used in 33% and 34% of patients, respectively. Overall mortality was 12% and was higher in patients diagnosed with MODS (59%) or who presented with some organ dysfunction. CONCLUSION: Organ dysfunction was frequent. Patients with some type of organ dysfunction or MODS presented higher mortality. Despite global and institutional guidelines focused on improving diagnosis and treatment, in less than half of the patients sepsis was adequately detected and first-hour IV fluids and antibiotics administration rates were below 70%.

Clinical Characteristics of Children With SARS-CoV-2 Infection in a Hospital in Latin America.

Objective: COVID-19 infections have shown a different behavior in children than in adults. The objective of this study was to describe the clinical characteristics and severity of SARS-CoV-2 infection in pediatric patients seen at a reference hospital in Colombia. Method: A descriptive, observational study in patients under the age of 18 years with a positive test for SARS-CoV-2 infection (RT-PCR or antigen) between April 2020 and March 2021. Multiple variables were studied, including demographic data, clinical characteristics, lab measurements, treatments administered, intensive care unit admission, and mortality. Results: A total of 361 patients were included of whom 196 (54%) were males. The median age was 3 years. Of all the patients, 65 (18%) were asymptomatic. The majority of patients had no comorbidities (n = 225, 76%). In those who were symptomatic (n = 296, 82%), the most frequent complaints were fever (n = 178, 60%), nasal congestion (n = 164, 55%) and cough (n = 149, 50%). Chest x-rays were normal in 73 patients (50%). When abnormalities were found, interstitial (29%) and alveolar (12%) patterns were the most prevalent. One hundred and fifty-seven children (53%) required general ward hospitalization, and 24 patients (8%) required pediatric intensive care admission. The global mortality was 0.8% (3 patients). Conclusions: The majority of cases were asymptomatic or mild. However, a significant percentage of patients required general ward admission, and some even required intensive care. The main symptom of COVID-19 infections in newborns was apnea. A second COVID-19 RT-PCR may be necessary to detect infections in critically ill patients with a high clinical suspicion of the disease if an initial test was negative.

Characterization of serum vitamin D levels in pediatric patients with chronic lymphocytic thyroiditis.

BACKGROUND: Chronic lymphocytic thyroiditis or Hashimoto's thyroiditis is the most frequent cause of acquired hypothyroidism in children. An association between low levels of 25-hydroxyvitamin D (25OH vitamin D) and the development of the disease have been detected. The aim of this study was to describe 25OH vitamin D levels in patients aged 5 to 18 years with a diagnosis of Hashimoto's thyroiditis in three pediatric endocrinology outpatient centers in Medellín, Colombia. METHODS: We conducted a cross-sectional observational study with retrospective data collection. We evaluated the sociodemographic characteristics, diagnoses, presence of comorbidities, and frequency of vitamin D deficiency. RESULTS: Sixty patients were included. The 25OH vitamin D levels were sufficient in 65% of the cases according to the Institute of Medicine (IOM) criteria and in 10% of the cases according to the Endocrine Society criteria. Serum calcium and phosphorus values were normal in 53% and 45% of the patients, respectively. All patients had normal magnesium and parathyroid hormone levels. No differences were found in the exploratory analysis when comparing 25OH vitamin D levels, thyroid antibody levels, and thyroid volume. CONCLUSIONS: In this chronic lymphocytic thyroiditis population, we did not find an increased prevalence of vitamin D deficiency according to IOM or the Endocrine Society criteria compared with previous data from the general population. No statistically significant differences were found in the exploratory analysis.

INTRODUCCIÓN: La tiroiditis linfocítica crónica o tiroiditis de Hashimoto es la causa más frecuente de hipotiroidismo adquirido en la edad pediátrica. Se ha detectado una asociación entre concentraciones bajas de 25-hidroxivitamina D (25OH vitamina D) y el desarrollo de la enfermedad. El objetivo de este trabajo fue describir las concentraciones de 25OH vitamina D en pacientes de 5 a 18 años con diagnóstico de tiroiditis linfocítica crónica en tres centros de consulta externa de endocrinología pediátrica enMedellín,Colombia. MÉTODOS: Se llevó a cabo un estudio observacional de corte transversal con recolección retrospectiva de la información. Se evaluaron características sociodemográficas, particularidades del diagnóstico, presencia de comorbilidad y frecuencia de deficiencia de vitamina D. RESULTADOS: Se incluyeron 60 pacientes. La concentración de 25OH vitamina D fue suficiente en el 65% de los casos según los criterios de Institute of Medicine (IOM) y en el 10% de los casos según los criterios de la Endocrine Society. Los valores de calcio y fósforo sérico fueron normales en el 53% y el 45% de los pacientes, respectivamente. Todos los pacientes presentaron concentraciones normales de magnesio y paratohormona. No se encontraron diferencias en el análisis exploratorio al comparar la concentración de 25OH vitamina D, de anticuerpos tiroideos y el volumen tiroideo. CONCLUSIONES: En esta población con tiroiditis linfocítica crónica no se encontró una mayor prevalencia de deficiencia de 25OH vitamina D según los criterios del IOM y de la Endocrine Society en comparación con datos previos de la población general. En el análisis exploratorio no se encontraron diferencias estadísticamente significativas.

Gelatin tannate for acute diarrhoea and gastroenteritis in children: a systematic review and meta-analysis.

OBJECTIVE: To determine the effectiveness and safety of gelatin tannate (GT) for reducing the duration of the acute diarrhoea and gastroenteritis (ADG) in children. DESIGN: Systematic review and meta-analysis. DATA SOURCES: MEDLINE, Embase, CINAHL, Cochrane Central Register of Controlled Trials, LILACS and grey literature, published from inception to October 2018. No language restrictions. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Randomised controlled trials in children with ADG, comparing GT with placebo. RESULTS: Of 797 titles identified, we included three studies (276 children). We performed a random effects model meta-analysis for the main outcome (diarrhoea duration). We did not find significant differences between GT and placebo for diarrhoea duration (mean difference (MD)=-15.85 hours; 95% CI -42.24 to 14.82, I2=92%; three studies), stool frequency at day 2 (MD=0.11 stools/day; 95% CI -0.39 to 0.62: I2=26%; two studies), diarrhoea at day 3 (risk ratio [RR]=0.46; 95% CI 0.06 to 3.47: I2=73%; two studies), vomiting (RR=1.31; 95% CI 0.95 to 1.80: I2=0%; two studies) or adverse events (RR=0.86; 95% CI 0.27 to 2.66: I2=0%; two studies). Most common adverse events included abdominal pain and nausea. CONCLUSION: The effect of GT was no different to placebo for mean diarrhoea duration (low certainty on the evidence) and stool frequency at day 2 (high certainty) and for the presence of diarrhoea at day 3 (very low certainty) of vomiting (moderate certainty) and of adverse events (low certainty).

Antiemetics in Children With Acute Gastroenteritis: A Meta-analysis.

CONTEXT: Several antiemetics have been used in children with acute gastroenteritis. However, there is still controversy over their use. OBJECTIVE: To determine the effectiveness and safety of antiemetics for controlling vomiting in children with acute gastroenteritis. DATA SOURCES: Medline, Embase, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, Latin America and the Caribbean Literature on Health Sciences, and gray literature, until December 2018. STUDY SELECTION: We selected randomized clinical trials comparing metoclopramide, ondansetron, domperidone, dexamethasone, dimenhydrinate, and granisetron. DATA EXTRACTION: Two reviewers independently screened abstracts and full texts, extracted the data, and assessed the risk of bias. We performed pairwise and network meta-analysis using the random-effects model. RESULTS: Twenty-four studies were included (3482 children). Ondansetron revealed the largest effect in comparison to placebo for cessation of vomiting (odds ratio = 0.28 [95% credible interval = 0.16 to 0.46]; quality of evidence: high) and for hospitalization (odds ratio = 2.93 [95% credible interval = 1.69 to 6.18]; quality of evidence: moderate). Ondansetron was the only intervention that reduced the need for intravenous rehydration and the number of vomiting episodes. When considering side effects, dimenhydrinate was the only intervention that was worse than placebo. LIMITATIONS: Most treatment comparisons had low- or very low-quality evidence, because of risk of biases and imprecise estimates. CONCLUSIONS: Ondansetron is the only intervention that revealed an effect on the cessation of vomiting, on preventing hospitalizations, and in reducing the need for intravenous rehydration. Ondansetron was also considered a safe intervention.

Acute Infectious Diarrhea and Gastroenteritis in Children.

PURPOSE OF REVIEW: We aimed to summarize the most current evidence on the main aspects of the diarrheal diseases in children. The following key elements were addressed: definitions, etiology, pathogenesis, diagnosis, dietary management, pharmacological treatments, and prevention. We covered the following questions: What are the most important clinical and laboratory features of the disease? What are the best approaches for the dietary management? What is the best way to classify the hydration status, and to prevent and treat the dehydration? What are the most effective and safe interventions for reducing the diarrhea and vomiting? RECENT FINDINGS: Diarrheal diseases are one of the most common diseases in childhood. The most common cause is rotavirus. A key element in the approach of a child with diarrhea is determining their hydration status, which determines the fluid management. Laboratory tests are nor routinely required, as most of the cases, they do not affect the management and it should be indicated only in selected cases. Several treatments have been studied to reduce the duration of the diarrhea. Only symbiotics and zinc have shown to be effective and safe with high certainty on the evidence. Rest of the interventions although seem to be effective have low to very low quality of the evidence. The only effective and safe antiemetic for controlling vomiting is ondansetron. A list of antimicrobials indications according to the identified microorganisms is provided. We summarized the most current evidence on diagnosis, management, and prevention of diarrhea in children. More research is needed in some areas such as dehydration scales, rehydration management, antidiarrheals, and antibiotic treatments.
