Early corticosteroid withdrawal is associated with improved adult height in pediatric kidney transplant recipients.

BACKGROUND: Catch-up growth after pediatric kidney transplantation (kTx) is usually insufficient to reach normal adult height. We aimed to analyze the effect of pre-transplant recombinant human growth hormone (rhGH) and corticosteroid withdrawal on linear growth in the first year after kidney transplantation and identify factors associated with final height (FH). METHODS: Patients who underwent kTx between 1996 and 2018 at below 18 years old in five Belgian and Dutch centers were included. We analyzed the differences between height Z-scores at kTx and 1 year post-transplant (Δ height Z-score) in children with and without corticosteroids at 1 year (CS + /CS -) and with and without rhGH treatment before kTx (rhGH + /rhGH -). Univariable and multivariable linear regression analysis was applied to identify factors associated with height Z-score at 1 year post-kTx, Δ height Z-score, and FH Z-score. RESULTS: A total of 177 patients were included, with median age 9.3 years at kTx. Median height Z-scores pre-kTx and 1 year later in the CS - /rhGH - , CS + /rhGH - , CS - /rhGH + , and CS + /rhGH + groups were - 1.42/ - 0.80, - 0.90/ - 0.62, - 1.35/ - 1.20, and - 1.30/ - 1.60 (p = 0.001). CS use 1 year post-kTx was the only factor associated with Δ height (p = 0.003) on multivariable analysis. CS use at 1 year was the only variable associated with FH (p = 0.014) in children with pre-transplant height Z-score below - 1 (n = 52). CONCLUSIONS: Increase in height Z-score in the first year post-kTx was highest in the CS - /rhGH - group and lowest in the CS + /rhGH + group. The use of corticosteroids at 1 year post-kTx is associated with catch-up growth and in children with pre-transplant height Z-score below - 1 also with final height.

Differences in Management of Eosinophilic Esophagitis in Europe: An Assessment of Current Practice.

OBJECTIVES: The aim of the study was to assess differences in the diagnosis and management of eosinophilic esophagitis (EoE) by European pediatric (PG) and adult gastroenterologists (AG), and their self-reported adherence to guidelines. METHODS: A multiple-choice questionnaire gauged the diagnostic and management strategies of gastroenterologists treating children or adults in 14 European countries and the United Arab Emirates (UAE). RESULTS: Questionnaires were completed by 465 PG and 743 AG. PG were significantly more likely to take biopsies in patients with symptoms of esophageal dysfunction (86.2% PG vs 75.4% AG, P < 0.001) and to perform endoscopic follow-up (86.3% PG vs 80.6% AG, P < 0.001). After failure of proton-pump inhibitors (PPIs), topical steroids were the preferred second-line therapy; however, PG opted more frequently for elimination diets (47.5% PG vs 13.7% AG, P < 0.001). More PG than AG indicated having read recent guidelines (89.4% PG vs 58.2% AG, P < 0.001). Geographic differences in practice were reported, with respondents from the United Kingdom, Portugal, and Spain more often adhering to recommended biopsy protocols. Physicians in the UAE, France, Lithuania, and Poland tended to opt for steroid therapy or elimination diets as first-line therapy, in contrast to most other countries. CONCLUSIONS: Significant differences in general practice between PG and AG were demonstrated with notable divergence from consensus guidelines. International practice variations are also apparent. Among other strategies, educational activities to highlight current recommendations may help harmonize and optimize clinical practice.

Juvenile Papillomatosis in a Young Child: A Case of Infantile Bloody Nipple Discharge.

BACKGROUND: Bloody nipple discharge (BND) is a rare and distressing finding in infants, although its etiology is usually benign. Diagnostic management of BND and breast lesions in children calls for an adapted approach. CASE: We present the case of an 11-month-old girl with unilateral BND and a painless breast mass. Sonographic and histologic examination identified juvenile papillomatosis of the breast. SUMMARY AND CONCLUSION: Juvenile papillomatosis of the breast is a rare cause of breast lesions in young patients with specific sonographic and histologic characteristics. Because of the associated risk of malignancy, surgical excision is the preferred therapy.
