Background Inflammatory bowel disease (IBD) is a chronic immune-mediated disease with high impact on nutritional status. Sarcopenia was related to higher risk of intestinal resection and rescue therapy in adult IBD patients; however, data in paediatric population is missing. The aim of this study was to evaluate muscle mass as a predictor of disease outcome in paediatric IBD. Methods All paediatric IBD patients that underwent a magnetic resonance enterography (MRE) study for disease assessment at the Tel Aviv Sourasky Medical Center in 2008–2019 were retrospectively included. Muscle mass was assessed by measuring the area of the psoas muscle at the upper level of L3 on MRE by a freehand region of interest (ROI). Psoas index was defined as the average psoas area divided by body surface area, and then was divided into quartiles. Disease location and radiological signs of IBD were documented. Clinical data including disease activity and course, medications, exacerbations and laboratory results were documented. Results We included 101 patients, 69 (68.3%) Crohn’s disease patients and 32 (31.7%) ulcerative colitis patients. The mean age was 13.05 ± 3.48 years at diagnosis and 15.03 ± 3.27 years at MRE. The psoas index was significantly lower in patients with presence of fatty proliferation (p = 0.021), comb sign (p = 0.001) and extensive disease in MRE (p = 0.012) and in radiologic evidence of disease complications such as abscess or fistula (p = 0.027). In a univariate analysis, patients with psoas index in the lower quartile had significantly higher risk of need for biologic therapy during follow-up (HR = 35.1, p < 0.001; Figure 1) and higher risk of disease exacerbation (HR = 25.1, p < 0.001; Figure 2) compared with patients with psoas index in the upper quartile. In a multivariate analysis adjusted for age, gender, disease type, haemoglobin, C-reactive protein, albumin, disease activity and interval from diagnosis to MRE, patients with psoas index in the lower quartile had significantly higher risk of need for biologic therapy (HR = 12.1, p = 0.046) and of disease exacerbation (HR = 9, p = 0.047) compared with patients with psoas index in the upper quartile. Conclusion Sarcopenia correlates with the radiological severity of IBD and was found to be an independent predictor for severe clinical disease course. Muscle mass in MRE studies may be used as a possible marker for disease outcome in paediatric IBD.
Background: Complex anatomical changes have been the main challenges for optimal treatment results of tear trough deformities through hyaluronic acid (HA) injections. The authors present a novel technique consisting of a preinjection tear trough ligament stretching (TTLS-I) leading to its release, and compared its efficacy, safety, and patient satisfaction to tear trough deformity injection (TTDI). Methods: This was a 4-year, retrospective, single-center cohort study of 83 TTLS-I patients, with a follow-up period of 1 year. One hundred thirty-five TTDI patients served as a comparison group. Outcome analyses included the analysis of possible risk factors for adverse outcome and comparative statistics between the complication and satisfaction rates of the two groups. Results: TTLS-I patients received significantly less HA (0.3 cc; range, 0.2 to 0.3 cc) than TTDI patients did (0.6 cc; range, 0.6 to 0.8 cc; P < 0.001). The injected HA amount was a significant predictive factor for complications (P < 0.05). Complication rates assessed during the follow-up visit for hematomas, edema, and the need for corrective hyaluronidase injection were low in both groups, with no significant differences between the groups. TTDI patients had significantly higher rates (5.1%) of lump surface irregularities during follow-up, compared with 0% in the TTLS-I group (P < 0.05). After 1 year of follow-up, 98.8% of TTLS-I patients were satisfied, whereas 95.6% of TTDI patients were satisfied, with no significant difference between groups. Conclusions: TTLS-I is a novel, safe, and effective treatment method, necessitating significantly less HA compared with TTDI. Moreover, it leads to very high satisfaction rates and very low complication rates. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
