CKD is a major co-morbidity in pediatric lung transplant recipients. We report the prevalence of renal impairment post-lung transplant at a single center, using a modified, age-adjusted eGFR for the best approximation of true GFR, and investigated associations and possible predictors of decline in renal function post-transplant. Renal function was assessed by eGFR pre-transplant, three and 12 months post-transplant, and at last follow-up. Decline in renal function was analyzed as percentage fall in eGFR in two phases (0-3 and 3-12). Furthermore, we investigated impact of gender, age, pre-transplant diagnosis and renal function, transplant type, early post-transplant dialysis, and tacrolimus trough levels on decline in eGFR using multivariate analysis. Over a five-yr period, 30 transplants were performed. Mean eGFR pretransplant was 117 mL/min/1.73 m(2) (s.d. 35) with mean decline in eGFR during the first three months post-transplant of 33% (s.d. 31, p < 0.001). Thereafter, mean decline in eGFR was 8% (s.d. 18, p = 0.02). None of the factors assessed were significantly associated with decline in eGFR post-transplant. In conclusion, many children have decline in renal function following lung transplantation, particularly early post-transplant. Unlike in adults, we were unable to detect any predictors of renal impairment in pediatric lung transplant recipients.

Background: Live attenuated influenza vaccine (LAIV) is recommended for annual influenza vaccination in children from age 2 years. However, some guidelines recommend against its use in children with asthma or recurrent wheeze due to concerns over its potential to induce wheezing. Objective: We sought to assess the safety of LAIV in children with moderate to severe asthma, and in preschool children with recurrent wheeze. Methods: Prospective, multicenter, open-label, phase IV intervention study in 14 specialist UK clinics. LAIV was administered under medical supervision, with follow-up of asthma symptoms 72 hours and 4 weeks late, using validated questionnaires. Results: A total of 478 young people (median, 9.3; range, 2-18 years) with physician-diagnosed asthma or recurrent wheeze were recruited, including 208 (44%) prescribed high-dose inhaled corticosteroids and 122 (31%) with severe asthma. There was no significant change in asthma symptoms in the 4 weeks after administration (median change, 0; P 5 .26, McNemar test), with no impact of level of baseline asthma control/symptoms in predicting either a worsening of asthma or exacerbation after LAIV using a regression model. A total of 47 subjects (14.7%; 95% CI, 11%-19.1%) reported a severe asthma exacerbation in the 4 weeks after immunization, requiring a short course of systemic corticosteroids; in 4 cases, this occurred within 72 hours of vaccination. No association with asthma severity, baseline lung function, or asthma control was identified. Conclusions: LAIV appears to be well tolerated in the vast majority of children with asthma or recurrent wheeze, including those whose asthma is categorized as severe or poorly controlled.

Background People with cystic fibrosis are at an increased risk of fat-soluble vitamin deficiency including vitamin E. Vitamin E deficiency can cause a host of conditions such as haemolytic anaemia, cerebellar ataxia and cognitive di iculties. Vitamin E supplementation is widely recommended in cystic fibrosis and aims to ameliorate this deficiency. This is an updated version of the review. Objectives To determine the e ects of any level of vitamin E supplementation on the frequency of vitamin E deficiency disorders in people with cystic fibrosis. Search methods We searched the Cochrane Group's Cystic Fibrosis Trials Register and also searched international trial registers for any ongoing clinical trials that were not identified during our register search.

A 2‐mo‐old infant born to a mother with Graves’ disease and having symptoms of thyrotoxicosis was started on antithyroid drugs. Life‐threatening hypocalcaemia requiring high‐dose calcium infusions developed 1 mo after starting therapy. Serum alkaline phosphatase and paratharmone levels were elevated. This communication may serve to alert treating physicians about this rare complication in infants with thyrotoxicosis after initiation of antithyroid therapy. Conclusion: Severe hypocalcaemia may follow initiation of antithyroid therapy in infants with thyrotoxicosis.
