Currently, there is a lack of easily accessible and reliable predictors for IVIG resistance. This study systematically evaluates the utility of baseline peripheral blood cell counts and their ratios in predicting IVIG non-response. METHODS: We assembled a retrospective cohort from the Children’s Hospital of Chongqing Medical University, including all KD patients admitted between January 1, 2023, and June 30, 2025. Patients were classified as either IVIG-responsive or IVIG-resistant based on the resolution of fever following the initial IVIG treatment. We compared baseline demographics, laboratory data, and coronary artery lesion (CAL) status. Univariable analysis was conducted to identify factors associated with IVIG resistance, and receiver-operating characteristic (ROC) curves were utilized to quantify predictive performance. RESULTS: Among the 210 children diagnosed with KD, 15 (7.1%) were classified as IVIG-resistant, while 195 (92.9%) were responsive to treatment. No significant differences were observed in sex, age at onset, or the frequency of CAL between the two groups; however, the hospital length of stay was significantly longer in the resistant cases (P < 0.001). Prior to IVIG treatment, the resistant group exhibited elevated neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and systemic immune-inflammation index (SII) (P = 0.003, 0.001, 0.013, 0.029, respectively), alongside a lower absolute lymphocyte count (P < 0.001). ROC analysis revealed that NLR (AUC 0.733; cut-off 1.07; sensitivity 100%, specificity 84.6%) and PLR (AUC 0.766; cut-off 64.43; sensitivity 100%, specificity 84.1%) were the most robust pre-treatment predictors of IVIG resistance. Following IVIG administration, responsive patients demonstrated significant alterations in multiple cellular parameters, whereas resistant patients exhibited only minimal changes. The extent of change was markedly different between the groups, particularly for PLR: PLR decreased in resistant patients but increased in responders. The difference in PLR before and after infusion (ΔPLR) provided excellent discrimination (AUC 0.840; cut-off 81.77; sensitivity 93.3%, specificity 90.3%). CONCLUSIONS: Elevated baseline NLR, PLR, MLR, and SII are identified as risk factors for IVIG resistance in KD. NLR values exceeding 1.07 and PLR values greater than 64.43 demonstrate high predictive value. A decline in post-treatment PLR of ≥ 81.77 serves as an additional strong indicator of non-response to IVIG. </p>","PeriodicalId":14511,"journal":{"name":"Italian Journal of Pediatrics","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13244895/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147771630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Individual variability in metabolic health—independent of obesity severity—has led to the concept of metabolically healthy obesity (MHO). This study aimed to evaluate the relationship between metabolic health status and systemic inflammatory indices in childhood obesity, including analyses adjusted for sex and pubertal stage to account for physiologic developmental changes. METHODS: This retrospective study included children with BMI SDS ≥ 2, categorised as Metabolically Unhealthy Obese (MUO) if they had ≥ 1 of the following: fasting glucose ≥ 100 mg/dL, HOMA-IR ≥ 2.5 (prepubertal) or ≥ 4 (pubertal), triglycerides ≥ 150 mg/dL, HDL ≤ 40 mg/dL, or systolic/diastolic blood pressure ≥ 95th percentile. Children with none of these findings were classified as MHO. Inflammatory indices—neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), systemic inflammation index (SII), and systemic immune-response index (SIRI)—were analysed using ROC curves and multivariable regression. Additional analyses adjusted for age, sex, pubertal stage, and BMI SDS were performed to account for developmental influences on inflammatory markers. RESULTS: A total of 388 obese children (58.1% female, mean age 11.5 ± 2.9 years) were included; 35.4% were morbidly obese, and 45.6% were classified as MUO. MUO children had significantly higher white blood cell, neutrophil, and monocyte counts, as well as higher fasting glucose, HOMA-IR, triglycerides, and total cholesterol, with lower HDL levels. Dyslipidemia was the most common metabolic abnormality. SII demonstrated strong discriminatory ability for metabolic health (AUC = 0.854; 82% sensitivity; 72% specificity). SII was positively associated with HOMA-IR, TG/HDL-C, and non-HDL cholesterol (p = 0.006; p = 0.004; p = 0.01, respectively). After adjustment for age, sex, pubertal stage, and BMI SDS, the associations of SII and SIRI with metabolic health status were attenuated but remained directionally consistent, indicating that developmental factors partially influence systemic inflammatory responses. CONCLUSION: The high prevalence of MUO among obese children highlights their substantial cardiometabolic risk burden. SII and SIRI appear to be promising, readily accessible biomarkers for identifying metabolic deterioration, showing meaningful correlations with key cardiometabolic risk indicators.

METHODS: We conducted a database analysis including Italian children aged 0–14 years between 2015 and 2024 using data from the Pedianet database, which contains anonymized electronic health records of over 275,000 children. CA-UTI episodes were identified through ICD-9-CM codes and free-text searches, then manually validated. All antibiotic prescriptions (classified by ATC codes and AWaRe classification) issued during each episode and associated to the CA-UTI were included. An interrupted time-series (ITS) analysis using a Poisson model was conducted to evaluate the impact of the 2019 national consensus guidelines on yearly antibiotic prescribing patterns in children aged 2 months to 3 years with a first episode of CA-UTI.

METHODS: A multidisciplinary board of 16 participants identified eight PICO (Population/Patient/Problem, Intervention, Comparator and Outcome) questions, including definition, signs and symptoms, risk factors, diagnostic tests, treatment and prognosis of gastroesophageal reflux (GER) and GERD in children: four PICO questions were related to the diagnosis of GERD.

The preprint “Impact of Regional heterogeneity of RSV infection prophylaxis on bronchiolitis in Italy” provides timely information for clinicians and health-system planners; however, several methodological specifications require clarification to ensure reproducibility and valid cross-regional comparability, particularly for the Emilia-Romagna Region. In Emilia-Romagna, programme choices were supported by a retrospective analysis of routinely collected hospital discharge and birth registry data (2015–2023), documenting that most of the RSV-associated hospital-admission burden is concentrated in infancy and follows a marked seasonal pattern, with severe outcomes largely confined to the first year of life. This evidence informed a risk-stratified approach during the initial roll-out. Using region-wide hospital discharge records from all Emilia-Romagna hospitals, we observed larger reductions between October 2023–March 2024 and October 2024–March 2025 than those presented as “regional” estimates in the preprint: total hospitalisations decreased from 1384 to 607 (−56.1%) among children aged < 14 years and from 1131 to 364 (−67.8%) among infants aged < 1 year; paediatric intensive care unit admissions decreased from 136 to 32 (−76.5%) and from 126 to 23 (−81.7%), respectively. To maximise the policy value of cross-regional comparisons and to support a more uniform, evidence-based national strategy in future seasons, key methods should be reported in a clear and standardised way.</p>","PeriodicalId":14511,"journal":{"name":"Italian Journal of Pediatrics","volume":"52 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13067385/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147654318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
