ABSTRACT
Despite the well-known role of obesity as risk factor for Juvenile Idiopathic Arthritis (JIA) severity, emerging but limited evidence suggested a similar role for underweight. We investigated the role of body mass index (BMI) across its full spectrum in a cohort of children with JIA.We retrospectively studied 113 children with JIA classified according to the International League of Association for Rheumatology (ILAR) criteria attending our Rheumatology Clinic. The patients underwent a comprehensive evaluation including both clinical and biochemical assessments. According to BMI Z-score, the cohort was divided into five groups as underweight, normal weight, overweight (OW), obesity (OB), and severe OB. Disease activity was calculated by Juvenile Arthritis Disease Activity Score 10 (JADAS-10) joint reduced count and relapses were defined according to Wallace criteria.The mean age of the cohort was 7.43 ± 4.03 years. The prevalence of underweight, normal weight, OW, OB, and severe OB was 7.2%, 54.1%, 10.8%, 17.1%, and 10.8%, respectively. Significant higher ferritin levels and erythrocyte sedimentation rate values were found in patients with severe OB and underweight compared to subjects belonging to normal weight, OW, and OB groups. A greater JADAS-10 score was observed in underweight patients and in those with severe OB than other groups. The relapse rate was higher in patients with severe OB and underweight compared to other groups. Conclusions: Both underweight and OB might negatively affect JIA course. Weight control is fundamental in children with JIA to avoid a more unfavourable course of the disease. What is Known: ⢠Obesity represents a well-known risk factor for JIA severity. ⢠The role of underweight in children with JIA is still poorly explored. What is New: ⢠As observed in children with obesity, underweight young patients with JIA seem to experience a more severe JIA course. ⢠Healthy lifestyle promotion in children with JIA is a crucial step in the management of the disease.

In addition to disease-specific complications, juvenile idiopathic arthritis (JIA) has been linked to metabolic impairments in adults. Recent data supported the usefulness of uric acid (UA) as risk factor for cardiometabolic derangements. Given the lack of pediatric evidence in this field, we aimed to explore this association in a cohort of children diagnosed with JIA. We retrospectively evaluated 113 children diagnosed with JIA classified according to the International League of Association for Rheumatology (ILAR) criteria attending our Rheumatology Clinic. Both clinical and biochemical assessments were performed. Participants were stratified in four groups according to quartiles of serum UA. Disease activity was calculated by the Juvenile Arthritis Disease Activity Score 10 (JADAS-10) joint reduced count, and cut-offs for disease states were applied. Patients belonging to the highest UA quartile showed higher serum triglycerides, total cholesterol, creatinine, and glucose levels (p = 0.01, p = 0.025, p = 0.04, and p = 0.005, respectively) and lower HDL cholesterol values (p < 0.0001) than subjects belonging to the lowest quartiles. Ferritin, erythrocyte sedimentation rate levels, and age at disease onset did not significantly differ across UA quartiles (all p > 0.05). As activity disease index, JADAS-10 score significantly increased across UA quartiles (p = 0.009). CONCLUSION: Children with JIA presented with a worse cardiometabolic profile and a greater disease severity across UA quartiles. Our findings suggest that in clinical practice, UA might represent a useful marker of cardiometabolic risk and disease severity in children with JIA. WHAT IS KNOWN: ⢠JIA has been linked to metabolic derangements in adulthood. ⢠UA has been recognized as a marker of cardiometabolic risk both in adults and children. WHAT IS NEW: ⢠Children with JIA belonging to the highest UA quartile showed a worse cardiometabolic profile and a greater disease severity. ⢠UA might represent a helpful marker not only of cardiometabolic risk but also of disease severity in children with JIA.

As a result of the obesity epidemic, non-alcoholic fatty liver disease (NAFLD) represents a global medical concern in childhood with a closely related increased cardiometabolic risk. Knowledge on NAFLD pathophysiology has been largely expanded over the last decades. Besides the well-known key NAFLD genes (including the I148M variant of the PNPLA3 gene, the E167K allele of the TM6SF2, the GCKR gene, the MBOAT7-TMC4 rs641738 variant, and the rs72613567:TA variant in the HSD17B13 gene), an intriguing pathogenic role has also been demonstrated for the gut microbiota. More interestingly, evidence has added new factors involved in the "multiple hits" theory. In particular, omics determinants have been highlighted as potential innovative markers for NAFLD diagnosis and treatment. In fact, different branches of omics including metabolomics, lipidomics (in particular sphingolipids and ceramides), transcriptomics (including micro RNAs), epigenomics (such as DNA methylation), proteomics, and glycomics represent the most attractive pathogenic elements in NAFLD development, by providing insightful perspectives in this field. In this perspective, we aimed to provide a comprehensive overview of NAFLD pathophysiology in children, from the oldest pathogenic elements (including genetics) to the newest intriguing perspectives (such as omics branches).
ABSTRACT
The relationship between nonalcoholic fatty liver disease (NAFLD) and chronic kidney disease (CKD) has gained considerable scientific interest in adults over the past few years. However, this association has recently emerged in children. Several published studies have suggested a role for NAFLD as a risk factor for CKD from the earliest age, with a potential influence of the major NAFLD risk polymorphisms, resulting in an increased risk of both cardiovascular and metabolic diseases. In view of the progressive course and increased cardiometabolic risk closely related to NAFLD and CKD, we focused on the link between these diseases in childhood.

RATIONALE: Henoch-Schönlein Purpura (HSP) is an acute small vessel vasculitis. It is the most common vasculitis in children. In majority of the cases, the disease is self-limited. Relapses can occur, in particular during the first year of the disease. There is no consensus on a specific treatment. The efficacy and safety of steroidal treatment in treating HSP is still controversial. Immunosuppressive treatment of HSP nephritis is used in patients with severe renal involvement (nephrotic range proteinuria and/or progressive renal impairment). The literature on immunosuppressive treatment of severe HSP without kidney involvement is scanty. PATIENTS CONCERNS: We report 2 case reports of 2 adolescents affected from Henoch-Schönlein Purpura and severe gastrointestinal involvement. Both patients presented a poor response to steroids treatment. DIAGNOSES: The diagnosis of HSP was made according to the diagnostic criteria published by European League against Rheumatism and Pediatric Rheumatology European Society in 2006. INTERVENTIONS: In consideration of the recurrence of the Henoch Schönlein Purpura and the gastrointestinal involvement, we decided to start Mycophenolate Mofetil treatment. OUTCOMES: In both patients all clinical manifestations resolved in few days. LESSONS: In our cases of HSP with gastrointestinal involvement Mycophenolate Mofetil treatment has been very effective. This experience teaches us that immunosuppressive agents may be very useful to induce and maintain remission not only in renal involvement, but in all cases of persistent, recurrent, or complicated Henoch Schönlein Purpura in children.
