Estimated C-reactive protein (CRP) velocity for rapidly distinguishing bacterial from other etiologies in children presenting to emergency department with remarkably elevated CRP levels.

The use of a single C-reactive protein (CRP) value to differentiate between bacterial and non-bacterial causes is limited. Estimated CRP velocity (eCRPv) has shown promise in enhancing such discrimination in adults. This study aims to investigate the association between eCRPv and bacterial etiologies among pediatric patients with very elevated CRP levels. We conducted a retrospective analysis of patients under 18 years of age who had been admitted to our Pediatric Emergency Department from 2018 to 2020 with a fever and CRP levels ≥ 150 mg/L. Bacterial and non-bacterial etiologies were determined from hospital discharge diagnoses, which were monitored independently by three physicians from the research team. The records of 495 suitable patients (51.2% males, median age 3.2 years) were retrieved of whom 444 (89.7%) were eventually diagnosed with bacterial infections. The mean CRP levels were significantly higher for bacterial etiologies compared with other causes (209.2 ± 59.8 mg/L vs. 185.6 ± 35.8 mg/L, respectively, p < .001), while the mean eCRPv values did not differ significantly (p = .15). In a time course analysis, we found that specifically in patients presenting ≥ 72 h after symptom onset, only a eCRPv1 level > 1.08 mg/L/h was an independent predictor of bacterial infection (aOR = 5.5 [95% CI 1.7-17.8], p = .004).   Conclusion: Pediatric patients with very high CRP levels and fever mostly have bacterial infections. eCRPv levels, unlike CRP values alone, can serve as the sole independent predictor of bacterial infection > 72 h from symptom onset, warranting further prospective investigations into CRP kinetics in pediatric patients. What is Known: • The use of a single C-reactive protein (CRP) value to differentiate between bacterial and non-bacterial causes is limited. • Estimated CRP velocity (eCRPv) has shown promise in enhancing such discrimination in adults, but data on CRP kinetics in pediatric patients is sparse. What is New: • eCRPv levels, unlike CRP values alone, can serve as the sole independent predictor of bacterial infection > 72 h from symptom onset in pediatric patients with remarkably elevated CRP levels.

Pott's Puffy Tumor in Pediatric Patients: Case Series and Literature Review.

BACKGROUND: Pott's puffy tumor (PPT) is a rare complication of frontal sinusitis. Although it may occur at any age, the incidence is higher during adolescence. METHODS: We report a series of 10 pediatric patients (9-17 years of age) who presented with PPT in 2 tertiary care pediatric hospitals in central Israel between January 2018 and August 2022 and review the published literature on pediatric PPT. RESULTS: The most common clinical presentations included headache (10 cases), frontal swelling (6 cases) and fever (5 cases). Symptom duration before admission was between 1 and 28 days (median 10 days). The diagnosis of PPT was made by imaging studies at a median of 1 day after admission. All 10 patients underwent computed tomography studies, and 6 patients also underwent magnetic resonance imaging. The overall rate of intracranial complications was 70%. All 10 children were treated with systemic antibiotics and surgical interventions. Streptococcus constellatus group was the most common causal bacteria. All 10 patients recovered uneventfully. CONCLUSIONS: Our findings show that a high index of suspicion for PPT should be applied to adolescents presenting with prolonged headache and frontal swelling. Contrast-enhanced computed tomography is an appropriate first tool for the evaluation; however, an magnetic resonance imaging should be performed to determine the necessity of intracranial interventional treatments if there is any suspicion of intracranial involvement. Complete recovery can be expected with appropriate antibiotic treatment and surgical intervention in most of the cases.

Elevated liver enzymes of newly diagnosed pediatric celiac patients-a prospective-observational study.

Celiac disease clinical presentation is constantly changing. We set to determine the prevalence of elevated transaminases in newly diagnosed celiac patients and to evaluate this sub-group of patients for associated clinical and laboratory findings and assess their natural course of disease following therapeutic diet initiation. We conducted a prospective-observational study of all newly diagnosed pediatric celiac patients, between August 2016 and April 2018, in a pediatric gastroenterology clinic. Clinical data, anthropometrics, and blood test results were recorded at diagnosis and at 3, 6, and 12 months, respectively, of follow-up. We compared patients with normal and elevated transaminases at diagnosis. ALT threshold was set at 24 U/l. Of 125 newly diagnosed celiac patients, 31 (24.8%) had elevated ALT at diagnosis; two (1.6%) with over 3 × ULN. Patients with elevated ALT at diagnosis were significantly younger (mean age 5.5 (SD 3.4) vs. 7.3 (SD 3.7) years, p < 0.01) and more commonly presented with diarrhea (32.3% vs. 14.9%, p = 0.03). Eighty percent of patients with elevated ALT levels normalized their ALT within 3 months and all within 1 year. Following gluten-free diet initiation, patients with elevated ALT had similar clinical course, growth, serology normalization rate, and laboratory results, compared to patients with normal ALT over a 1-year follow-up. A single patient was simultaneously co-diagnosed with celiac disease and autoimmune hepatitis.Conclusion: Clinically significant ALT abnormalities are rare among newly diagnosed pediatric celiac patients. Significant elevations failing to normalize on a gluten-free diet should raise concern of a concomitant primary liver disease and warrant further investigations. What is Known: • Elevated liver enzymes may be an extra-intestinal manifestation of celiac disease. • Reported prevalences of ALT elevations among children with a new diagnosis of celiac disease ranges between 5 and 40%. What is New: • ALT elevations are present in 25% of children with a new diagnosis of celiac disease. • Significant elevations (>3 × ULN) are rare (1.6%). • Elevated liver enzymes are associated with earlier age at diagnosis. • The natural history of patients with elevated liver enzymes at diagnosis is comparable to those without.
