RESUMO
OBJECTIVES: The pediatric Glucocorticoid Toxicity Index (pGTI) is a new, pediatric-specific tool to quantify glucocorticoid (GC)-related morbidity in children. We evaluated the feasibility and construct validity of retrospective pGTI scoring in patients with pediatric-onset systemic lupus erythematosus (pSLE) and identified risk factors for cumulative toxicity. METHODS: We conducted a retrospective cohort study of patients with pSLE treated with GCs at two pediatric centers (1999-2023). GC exposure was estimated using interval-averaged oral prednisone-equivalent dose and cumulative prednisone-equivalent dose. We scored change in GC toxicity every 6 months (±2) using a modified pGTI including 7 of 10 domains. We calculated the Cumulative Worsening Score (CWS), a continuous summation of toxicity accrued. Mixed effects linear regression was used to identify factors associated with CWS. RESULTS: There were 126 patients with pSLE, including 88 with nephritis, with a median of 6 visits/patient. Nearly half (47 %) experienced toxicity in the Blood Pressure domain. Other common toxicities were mood disturbance (25 %), followed by increased body mass index (BMI), striae, and sleep disturbance (21 % each). Decreased growth velocity was observed in 18 %. There was modest correlation between cumulative GC dose and CWS (rho 0.3; p < 0.01). Greater cumulative toxicity was associated with younger age, elevated BMI, and rituximab use at the time of GC initiation, albeit indications for the latter were not captured. CONCLUSIONS: Patients with pSLE experience a high burden of GC toxicity, particularly related to blood pressure, BMI, sleep, and growth. Standardized, pediatric-specific GC toxicity assessment is feasible in real-world settings and can facilitate evaluation of strategies to reduce morbidity in children requiring chronic GC treatment.

Certain sociodemographic factors are associated with low technology access and digital healthy literacy.
RESUMO
The nummular phenotype of atopic dermatitis is clinically characterized by pruritic, coin-shaped plaques that are frequently recalcitrant to treatment. In this study, a retrospective chart review was conducted to evaluate the effectiveness and safety of dupilumab in children with nummular lesions of dermatitis. Twelve out of 14 patients demonstrated significant clinical improvement at a median time of 2.5 months (interquartile range, 1-4) after dupilumab initiation. A single case of paradoxical psoriasiform eruption was the only side effect reported in our cohort.

Urticaria in infants can cause significant anxiety in parents, especially if a trigger cannot be identified. In a retrospective study of 246 infants seen for urticaria of unknown etiology at Boston Children's Hospital, 88.2% had resolution of urticaria within 6 weeks. The etiology of urticaria was ultimately established in 62.6% (72/115) of acute urticaria and 12.5% (2/16) of chronic urticaria cases with follow-up data. Pediatric healthcare providers can counsel families that while etiology of urticaria is never determined in over 40% of infants, symptoms are most likely to resolve spontaneously.

Alcohol is a well-known risk factor for hepatocellular carcinoma. Autophagy plays a dual role in liver cancer, as it suppresses tumor initiation and promotes tumor progression. Transcription factor EB (TFEB) is a master regulator of lysosomal biogenesis and autophagy, which is impaired in alcohol-related liver disease. However, the role of TFEB in alcohol-associated liver carcinogenesis is unknown. Liver-specific Tfeb knockout (KO) mice and their matched wild-type (WT) littermates were injected with the carcinogen diethylnitrosamine (DEN), followed by chronic ethanol feeding. The numbers of both total and larger tumors increased significantly in DEN-treated mice fed ethanol diet than in mice fed control diet. Although the number of tumors was not different between WT and L-Tfeb KO mice fed either control or ethanol diet, the number of larger tumors was less in L-Tfeb KO mice than in WT mice. No differences were observed in liver injury, steatosis, inflammation, ductular reaction, fibrosis, and tumor cell proliferation in DEN-treated mice fed ethanol. However, the levels of glypican 3, a marker of malignant hepatocellular carcinoma, markedly decreased in DEN-treated L-Tfeb KO mice fed ethanol in comparison to the WT mice. These findings indicate that chronic ethanol feeding promotes DEN-initiated liver tumor development, which is attenuated by genetic deletion of hepatic TFEB.
