Abstract
Growth retardation is a major complication in children with chronic kidney disease (CKD) and on kidney replacement therapy (KRT). Conversely, better growth in childhood CKD is associated with an improvement in several hard morbidity-mortality endpoints. Data from pediatric international registries has demonstrated that improvements in the overall conservative management of CKD, the search for optimal dialysis, and advances in immunosuppression and kidney transplant techniques have led to a significant improvement of final height over time. Infancy still remains a critical period for adequate linear growth, and the loss of stature during the first years of life influences final height. Preliminary new original data from the European Society for Paediatric Nephrology/European Renal Association-European Dialysis and Transplant Association (ESPN/ERA-EDTA) Registry confirm an association between the final height and the height attained at 2 years in children on KRT.

Abstract
BACKGROUND Improved management of growth impairment might have resulted in less growth retardation after pediatric kidney transplantation (KT) over time. We aimed to analyze recent longitudinal growth data after KT in comparison to previous eras, its determinants, and the association with transplant outcome in a large cohort of transplanted children using data from the European Society for Paediatric Nephrology/European Renal Association and European Dialysis and Transplant Association Registry. METHODS A total of 3492 patients transplanted before 18 years from 1990 to 2012 were included. Height SD scores (SDS) were calculated using recent national or European growth charts. We used generalized equation models to estimate the prevalence of growth deficit and linear mixed models to calculate adjusted mean height SDS. RESULTS Mean adjusted height post-KT was -1.77 SDS. Height SDS was within normal range in 55%, whereas 28% showed moderate, and 17% severe growth deficit. Girls were significantly shorter than boys, but catch-up growth by 5 years post-KT was observed in both boys and girls. Children <6 years were shortest at KT and showed the greatest increase in height, whereas there was no catch-up growth in children transplanted >12. CONCLUSIONS Catch-up growth post-KT remains limited, height SDS did not improve over time, resulting in short stature in nearly half of transplanted children in Europe.

Abstract
OBJECTIVES Predicting the risk of posthepatectomy liver failure is important when performing extended hepatectomy. However, there is no established method to evaluate liver function and improve preoperative liver function in pediatric patients. MATERIALS AND METHODS We show the clinical features of pediatric patients who underwent living donor liver transplant for posthepatectomy liver failure in hepatoblastoma. The subjects were 4 patients with hepatoblastoma who were classified as Pretreatment Extent of Disease III, 2 of whom had distal metastasis (chest wall and lung). RESULTS Hepatic right trisegmentectomy was performed in 3 patients and extended left hepatectomy in 1 patient. The median alpha-fetoprotein level at the diagnosis of hepatoblastoma was 986300 ng/mL (range, 22500-2726350 ng/mL), and the median alpha-fetoprotein level before hepatectomy was 8489 ng/mL (range, 23-22500 ng/mL). The remnant liver volume after hepatectomy was 33.3% (range, 20% to 34.9%). Four patients had cholangitis after hepatectomy and progressed to posthepatectomy liver failure. The peak serum total bilirubin after hepatectomy was 11.4 mg/dL (range, 8.7-14.6 mg/dL). Living donor liver transplant was performed for these 4 patients with posthepatectomy liver failure, and they did not have a recurrence. CONCLUSIONS When the predictive remnant liver volume by computed tomography-volumetry before extended hepatectomy for patients with hepatoblastoma is less than 40%, the possibility of posthepatectomy liver failure should be recognized.

Abstract
INTRODUCTION Growth retardation is a common problem in children with CKD. This study aims to describe growth, prevalence of short stature before RTx, catch-up growth after RTx, and associated factors. METHODS We retrospectively reviewed 74 renal allograft recipients who underwent RTx at Fundación Cardioinfantil, Colombia, between January 2008 and September 2016 with follow-up for 2 years afterwards. Pre-RTx Height_SDS and demographic characteristics were compared between children with normal and short stature. Post-RTx Height_SDS at 1 and 2 years post-RTx and FAH, when available, were retrieved. Children were classified into catch-up growth and no catch-up growth groups depending on whether or not Height_SDS increased ≥0.5 per year within the first 2 years post-RTx. Possible associated factors were compared. RESULTS Seventy-four patients were included. Mean age at RTx was 11 ± 4.0 years, and 43.2% (32/74) were females. Mean Height_SDS for the entire study population at pre-RTx was -2.8 ± 1.5. Before RTx, 68.9% (51/74) had short stature, and 44.6% (33/74) had severe short stature. 37.2% presented catch-up growth post-RTx. Time on dialysis was associated with short pre-RTx stature (OR 1.66; 95% CI [1.15-2.39]; P = .006) and catch-up growth (OR 2.15; 95% CI [1.15-3.99]; P = .016). 44.59% (33/74) reached FAH, and 48.4% (16/33) presented short FAH. CONCLUSIONS Growth continues to be suboptimal after RTx. Given that pre-RTx height is a significantly associated factor, it is important to plan early interventions in terms of growth improvement in these children.

Catch-up growth in children with chronic kidney disease started on enteral feeding after 2 years of age. Pediatr Nephrol 2020; 35:113-118. [PMID: 31646404 PMCID: PMC6901400 DOI: 10.1007/s00467-019-04382-9] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Revised: 07/27/2019] [Accepted: 09/25/2019] [Indexed: 02/02/2023]
Abstract
BACKGROUND Enteral feeding by tube in chronic kidney disease (CKD) before 2 years of age improves growth. Whether it is effective after this age is unknown. We assessed whether height and weight SDS changed after tube feeding was started in children with CKD above 2 years of age. METHODS Retrospective study of pre-transplant, pre-pubertal children (< 11 years) with CKD stages 2-5 started on nasogastric tube or gastrostomy feeds for the first time after age 2 years. Children were identified by searching dietetic records and the renal database. Children on growth hormone were excluded. Height, weight, and BMI were documented 1 year prior to and at the start of tube feeds, and after 1 and 2 years. Data collection ceased at transplantation. RESULTS Fifty children (25 male) were included. The median (range) age at start of tube feeds was 5.6 (2.1-10.9) years. Sixteen children were dialysed (1 haemodialysis, 15 peritoneal dialysis); 34 predialysis patients had a median (range) eGFR of 22 (6-88) ml/min/1.73 m2. Overall height SDS (Ht SDS) improved from - 2.39 to - 2.27 at 1 year and - 2.18 after 2 years (p = 0.02). BMI SDS improved from - 0.72 to 0.23 after 1 year and was 0.09 after 2 years of enteral feeding (p < 0.0001). Height SDS improved more in children aged 2-6 years (- 2.13 to - 1.68, p = 0.03) and in children not on dialysis (- 2.33 to - 1.99, p = 0.002). CONCLUSIONS Enteral tube feeding commenced after 2 years of age in prepubertal children with CKD improves height and weight SDS, with stability of BMI during the second year. Younger children and those not on dialysis had the greatest benefit.

Abstract
Introduction: Growth retardation is one of the main complications of chronic kidney disease (CKD) in children and induces a negative impact on quality of life. Materials and Methods: Retrospective analysis of all consecutive patients younger than 18 years old who received a first KT in our center between 2008 and 2018. Results: 95 first KT recipients, median age at KT of 7.83 years. At the time of KT, 65.52% of males and 54.05% females showed normal height. After transplantation, linear growth improved from -1.53 at transplant to -1.37 SDS height at the last visit. We detected a different linear growth pattern according to patient age at KT. Children younger than 3 years old exhibited the most significant growth retardation at baseline and the greatest linear growth over time (-2.29 vs. -1.82 SDS height), whereas catch-up was not observed in older patients. Multivariate analysis showed that use of corticosteroids was negatively related to SDS height at 1 year after transplantation and final SDS height only was positively associated with SDS height at KT. 44.2 and 22.1% patients received rhGH treatment before and after KT. 71.88% patients reached adulthood with normal final height. Conclusions: In our study, pediatric KT recipients exhibited a normal height in more than half of cases at KT and in more than two thirds at the final adult height. Only children younger than 6 years old presented a relevant growth catch-up after KT. Treatment with rhGH was used before and after KT with significant improvement in height.

Abstract
BACKGROUND Growth retardation is a common problem for children with chronic kidney disease. Although renal transplantation (RTx) resolves endocrine metabolic and uremic disturbances, growth continues to be suboptimal. This study aims to describe changes in height from diagnosis to final adult height (FAH) in Korean renal allograft recipients and determine factors associated with posttransplantation growth. METHODS We retrospectively reviewed 63 renal allograft recipients who underwent RTx at <15 years of age with regular follow-up for >3 years afterwards. Pre- and post-RTx growth was analyzed by height Z scores (Ht_Z) at RTx, 2 and 5 years follow-up, and at FAH. RESULTS Ht_Z decreased from diagnosis to dialysis by -0.8 (P = .009) and from dialysis to RTx by -0.46 (P < .001). The mean baseline Ht_Z at RTx was -1.62 ± 1.36. The change in Ht_Z at 2 and 5 years after transplantation was 0.68 ± 0.88 and 0.48 ± 0.86, respectively. Both variables were negatively correlated with baseline age at RTx. Mean FAH was -1.22 ± 1.11 and was positively correlated with baseline height at RTx. Height at start of dialysis and dialysis duration were significant determinants of baseline height at RTx (P < .001). CONCLUSIONS Although there is significant posttransplant catch-up growth among younger recipients and among those with greater baseline height deficit, catch-up growth is not sustained and greater FAH is attained in those who are taller at RTx. Achieving greater height before dialysis and decreasing dialysis duration leads to maximal height at RTx as well as greater FAH.

Abstract
BACKGROUND Achieving a normal final adult height (FH) remains a challenge in the field of pediatric kidney transplantation (KTx). To examine the optimal approach to assuring normal FH following KTx, we retrospectively examined the post-transplant growth and FH of pediatric KTx recipients. METHODS Since the relevant factors affecting the FH of children following KTx are multifactorial and notably complex, KTx recipients with persistent good graft function and successful steroid minimization until FH attainment were selected for this study. RESULTS Thirteen patients were enrolled in this study. The mean estimated glomerular filtration rate was 72.1 ± 15.3 ml/min/1.73 m(2), and the mean corticosteroid dose was 0.05 ± 0.05 mg/kg on alternate days at the time of FH attainment. Despite highly successful KTx, four (30.8 %) patients (one who underwent KTx before puberty and three during puberty) showed a decrease in the height standard deviation score (hSDS) from the time of KTx until FH attainment. Moreover, of these, two male patients had an FH with an SD <-2. CONCLUSION FH remained suboptimal despite highly successful KTx. Not only highly successful KTx but also further treatment such as steroid avoidance, early steroid withdrawal or using rhGH might be necessary to assure a normal FH in some pubertal patients.

Abstract
Data on long-term outcomes after pediatric renal transplantation (Tx) are still limited. We report on a 20-year single-center experience. Medical charts of all consecutive pediatric Tx performed between 1987 and 2007 were reviewed. Data of patients who had been transferred to adult units were extracted from the French databases of renal replacement therapies. Outcomes were assessed using Kaplan-Meier and Cox models. Two hundred forty Tx were performed in 219 children (24.1% pre-emptive and 17.5% living related donor Tx). Median age at Tx was 11.1 years and median follow-up was 10.4 years. Patient survival was 94%, 92%, and 91% at 5, 10, and 15 years post-Tx, respectively. Overall, transplant survival was 92%, 82%, 72%, and 59% at 1, 5, 10, and 15 years post-Tx, respectively. The expected death-censored graft half-life was 20 years. Sixteen patients developed malignancies during follow-up. Median height at 18 years of age was 166 cm in boys and 152 cm in girls with 68% of patients being in the normal range. The proportion of socially disadvantaged young people was higher than in general population. Excellent long-term outcomes can be achieved in pediatric renal Tx, but specific problems such as malignancies, growth, and social outcome remain challenging.

Abstract
Interest in intensified hemodialysis (HD) regimens is increasing internationally, as there is growing evidence that they are associated with improved outcomes. Appreciation that conventional hemodialysis (CHD), delivered as 4-hour sessions three times a week, is not providing optimal physiological replacement of renal function has led to the development of intensified dialysis therapies. These include long intermittent hemodialysis typically lasting 6-8 hours and delivered three times a week, short daily hemodialysis, providing more frequent sessions 4-7 days a week lasting 2-3.5 hours, and nocturnal hemodialysis, performed 5-7 days a week for 6-8 hours. Studies evaluating outcomes from these programs have indicated superior results to those achieved with CHD, including favorable modifications of cardiovascular risk factors and improvements in a variety of clinical measures. The objective of this review is to present available evidence supporting the hypothesis that in an attempt to provide a "more normal physiology," intensified HD regimens achieve outcomes superior to those historically achieved with CHD.

Abstract
BACKGROUND This study was conducted to evaluate the pubertal development in adolescents after renal transplantation (RTx) in childhood. METHODS We performed a retrospective review of medical records of 109 RTx recipients (72 males) transplanted at the median age of 4.5 years (range: 0.9-15.8 years). Data on the clinical signs of puberty, growth, bone age, medication, and graft function of 98 patients were analyzed. Furthermore, serum levels of reproductive hormones in 87 patients were assessed to evaluate the progression and outcome of pubertal development. RESULTS The age at the onset of puberty averaged 12.7 years (range: 9.4-16.2 years) in 55 males and 10.7 years (range: 8.9-12.7 years) in 29 females. The mean age at menarche was 12.5 years (range: 10.5-14.5 years). Twenty-two percent of the boys and none of the girls had a moderately delayed onset of puberty. Children who underwent RTx before the age of 5 years reached puberty earlier than those transplanted at later age (boys 12.3±1.2 vs. 13.4±1.5 years, P<0.01; girls 10.3±0.9 vs. 11.0±1.0 years, P>0.05). The mean length of puberty was 3.9 and 4.7 years for boys and girls, respectively. The bone age was delayed in practically all, and final height was reached at the mean age of 18.1 and 16.0 years in boys and girls, respectively. Pubertal maturation resulted in acceptable final height and reproductive hormone status in great majority of the patients. CONCLUSION Pubertal development was normal in all female and most male adolescents after RTx in childhood.

Abstract
BACKGROUND AND OBJECTIVES In 2000, we reported the outcome of 101 children with a GFR <20 ml/min per 1.73 m2 at 0.3 yr of age (range 0.0 to 1.5 yr). Long-term data on such young children are scarce. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Mortality, treatment modalities, and growth were reanalyzed 9.9 yr later. RESULTS Of the 101 patients, 28 died and three were lost to follow-up during 13.90 yr (range 0.03 to 22.90 yr). One-, 2-, 5-, 10-, 15-, 20-, and 22-yr survivals were 87, 81, 77, 75, 73, 72, and 64%, respectively. Fifty-one children had comorbidities. Sixty-six percent were tube fed for 1.7 yr (range 0.1 to 6.9 yr), 37% had a gastrostomy, and 13% had a Nissen fundoplication. Mean height SD score (SD) was -0.42 (2.33) at birth (n = 40), -2.07 (1.34) at 0.5 (n = 62), -1.93 (1.38) at 1 (n = 72), -1.14 (1.14) at 5 (n = 67), -1.04 (1.15) at 10 (n = 62), -1.84 (1.32) at 15 (n = 40), and -1.68 (1.52) at age > or =18 yr (n = 32). Comorbidities adversely influenced growth (P < 0.01) and final height (P = 0.02): Mean height SD score (SD) was -1.16 (1.38) in otherwise normal adults. CONCLUSIONS Growth and final height in infants with severe chronic kidney disease are influenced by comorbidity. Intensive feeding and early transplantation resulted in a mean adult height within the normal range in patients without comorbidities. Overall mortality is comparable to that of older children.

Abstract
The 2009 Kidney Disease: Improving Global Outcomes (KDIGO) clinical practice guideline on the monitoring, management, and treatment of kidney transplant recipients is intended to assist the practitioner caring for adults and children after kidney transplantation. The guideline development process followed an evidence-based approach, and management recommendations are based on systematic reviews of relevant treatment trials. Critical appraisal of the quality of the evidence and the strength of recommendations followed the Grades of Recommendation Assessment, Development, and Evaluation (GRADE) approach. The guideline makes recommendations for immunosuppression, graft monitoring, as well as prevention and treatment of infection, cardiovascular disease, malignancy, and other complications that are common in kidney transplant recipients, including hematological and bone disorders. Limitations of the evidence, especially on the lack of definitive clinical outcome trials, are discussed and suggestions are provided for future research.

Abstract
Growth may be severely impaired in children with chronic renal insufficiency. Since short stature can have major consequences on quality of life and self-esteem, achieving a 'normal' height is a crucial issue for renal transplant recipients. However, despite successful renal transplantation, the final height attained by most recipients is not the calculated target height. Catch-up growth spurts post-transplantation are usually insufficient to compensate for the retardation in growth that has occurred during the pre-transplant period. Longitudinal growth post-transplantation is therefore influenced by the age at transplantation but also by subsequent allograft function and steroid exposure, both of which interfere with the growth hormone/insulin-like growth factor axis. The management of growth retardation in renal transplant recipients includes adequate nutritional intake, correction of metabolic acidosis, prevention of bone disease, steroid-sparing strategies and a supraphysiological dose of recombinant human growth hormone in selected cases.

Abstract
In a retrospective, single-center cohort study, outcomes of infants and toddlers undergoing lung transplant at St. Louis Children's Hospital between 1990 and 2004 were compared to older children. Patients with cystic fibrosis (exclusively older children) and those who underwent heart-lung, liver-lung, single lung or a second transplantation were excluded from comparisons. One hundred nine lung transplants were compared. Thirty-six were in infants <1 year old, 26 in toddlers 1-3 years old and 47 in children >3 years old. Graft survival was similar for infants and toddlers (p = 0.35 and p = 0.3, respectively) compared to children over 3 years old at 1 and 3 years after transplant. Significantly more infants (p < 0.0001 and p = 0.003) and toddlers (p = 0.002 and p = 0.03) were free from acute rejection and bronchiolitis obliterans compared to older patients. While most infants and toddlers had only minimal lung function impairment, and achieved normal to mildly delayed developmental scores, somatic growth remained depressed 5 years after transplant. Lung transplantation in infants and young children carries similar survival rates to older children and adults. Further insights into the unique immunologic aspects of this group of patients may elucidate strategies to prevent acute and chronic rejection in all age groups.

Abstract
Growth is an important feature of childhood, but it is usually impaired before and after organ transplantation. Modest catch-up growth often occurs after renal transplantation. Nevertheless, patients remain short due to the effects of steroids used for immunosuppression. Children with chronic liver failure are also growth impaired, although not to the same extent. They also frequently have poor catch up growth after transplantation, again due to steroids. There are several randomized controlled clinical trials reporting growth hormone (GH) use after renal transplantation. These consistently show a beneficial effect of GH on linear growth. Patients with histories of frequent acute rejections before GH may have increased risk of acute rejection during treatment. Few data exist on liver transplant patients, although GH also appears effective. GH use may be safe and effective for renal transplant recipients who have been stable without acute rejection episodes. There needs to be long-term study of GH use in liver and renal transplant patients. It is critical to focus efforts on improving growth in renal failure before transplantation through GH use and to improve posttransplant growth in all recipients by minimizing steroid exposure.

Abstract
Seventy-two pediatric kidney recipients of living related donors (LRD) and 145 of cadaveric donors (CAD) were analyzed for height standard deviation scores (Ht-SDS) and glomerular filtration rates (GFR) directly after transplantation and over the following 5 years. GFR was significantly higher immediately after transplantation in LRD compared with CAD recipients; however, GFR was not different during the 5-year follow-up period. Although Ht-SDS was comparable at the time of transplantation in both groups, it was significantly higher among LRD recipients over the next 5 years. Multivariate and covariate analyses showed that Ht-SDS after 5 years was mainly influenced only by CAD vs LRD and not by GFR or other factors, namely, donor age, rejections, time of dialysis, preemptive transplantation, age at transplantation, or immunosuppression. Thus, children receiving grafts from LRD showed a better catch-up growth independent of the GFR than those after CAD transplantation. We concluded that the period of donor death and prolonged cold ischemia in CAD grafts may lead to changes in gene expression of cytokines and other mediator molecules that affect bone metabolism. Better growth seems to be an additional factor supporting the policy of LRD kidney transplantation as the best option in children.

Abstract
The extent to which growth after renal transplantation differs between children with a living related donor graft (LRD) and those with a cadaveric donor graft (CAD) is unclear. We retrospectively studied growth in the 5 years after transplantation in 30 boys who received LRD and 21 who received CAD. Height was similar in both groups after transplantation but was greater in LRD than in CAD recipients during follow-up. LRD recipients were taller at all ages, and had greater growth velocity in infancy and during puberty. Glomerular filtration rate (GFR) was higher immediately after transplantation in LRD than in CAD recipients, but did not differ between the groups during follow-up. GFR and other factors did not affect height 5 years after transplantation. These findings support use of LRD as the preferred option in children.

Abstract
BACKGROUND Severe growth failure is frequently observed in children suffering from end-stage renal disease (ESRD). METHODS We analyzed the effect of renal transplantation (RTx) on longitudinal growth and final height in 37 children (19 girls) with ESRD with a mean follow-up of 8.5 years. The mean age at RTx was 11.3 years. RESULTS In children transplanted before start of puberty, mean height velocity increased significantly from 4.9 to 8.0 cm/year (P < 0.01), resulting in an increase in standardized height of 0.6 SD within two years post RTx. Although peak height velocity during puberty was significantly increased compared with healthy children, total pubertal height gain was reduced by 20% because of its shortened duration. Mean standardized height significantly increased from the time of RTx until final height by 1.3 SD and 0.7 SD in children transplanted before and after start of puberty, respectively. Mean adult height (boys 170 cm; girls 151 cm) was normal (> -2 SD) in 68% of patients. Change in standardized height from RTx until adult height was associated with initial degree of stunting and glomerular filtration rate (GFR; cumulative r2 0.49). Total pubertal height gain was associated with the age at start of puberty, GFR, and age at RTx (cumulative r2 0.57). CONCLUSION RTx in children with ESRD induces moderate catch-up growth during the prepubertal growth period. However, final height is reduced in about one third of patients due to the reduced pubertal height gain and preexisting height deficit at the time of RTx.

Abstract
Children undergoing successful renal transplantation anticipate optimal growth and development. The use of rhGH pre- and post-Tx has been evaluated and supported by randomized control trials. Several strategies are required to maximize the potential benefit of this treatment in the renal population including provision of adequate nutrition intake, following bone parameters with appropriate interventions, and strategies to reduce steroid therapy including utilization of alternate day steroid treatment. Studies are required to further assess the impact of rhGH on renal allograft function, rejection risk, and allograft ultrastructural changes.

Abstract
Long-term outcome of growth and final adult height (FH) are a major concern of children after a renal transplantation (Tx). We therefore studied the yearly measurements of height (Ht), expressed as the Z-score and bone age (BA), in 58 children (28 girls) transplanted in our departments and followed-up for 5-18 (mean 9.6) yr after the operation. Twenty-four children reached final adult height. Renal function was evaluated as the glomerular filtration rate (GFR), which is estimated from the clearance of inulin. The mean Ht Z-score at Tx was -1.3 in girls and -2.7 in boys and increased to -0.6 and -1.5, respectively, at 5 yr after Tx. The greatest increase, seen in the shortest children and those transplanted before 7 yr of age, occurred during the first 3 yr. Children aged 7-12 yr at Tx showed an increase in height during the first years after the transplant, while those transplanted at >12 yr of age were not growth-retarded and therefore did not change their Ht Z-score. The most growth-retarded were also the most BA retarded. The mean FH Z-score was -1.1. A direct correlation was seen between GFR at 1 yr after Tx and the increase in height Z-score from Tx to 1 and 5 yr after Tx. In summary, the increment in height following Tx was the greatest in the most growth-retarded children and most marked during the first 3 yr after the transplant. FH was within normal range in 75% of the children. A high Ht Z-score at Tx had a positive effect on FH. Thus, growth after Tx was affected by the degree of stunting at Tx and renal function after Tx.

Abstract
The complex issues related to the growth and development of pediatric kidney transplant recipients are explored in this paper. We divide the pediatric population into 3 age groups—toddlers and preschoolers, school age children, and adolescents—and review the literature describing growth and development in kidney transplant recipients and the normal population briefly for each age group. Planning and delivery of nursing care that is based on the implications of growth and development are discussed, and have relevance for all allied healthcare professionals caring for pediatric kidney transplant recipients and their parents. Allied healthcare professionals in adult settings who provide care to recipients who received a transplant before the age of 18 may also benefit from reviewing this article.

Abstract
Delayed puberty can be defined as the lack of pubertal development at an age of 2 SD above the mean, which corresponds to an age of approximately 14 years for males and 13 years for females, taking both sex and ethnic origin into consideration. Its incidence associated with chronic illnesses is unknown; however, its clinical importance is relevant due to the larger percentage of patients with chronic disorders surviving until the age of puberty. Virtually every child with any chronic disease could present with delayed puberty (due to recurrent infections, immunodeficiency, gastrointestinal disease, renal disturbances, respiratory illnesses, chronic anaemia, endocrine disease, eating disorders, exercise and a number of miscellaneous abnormalities). Pubertal delay associated with chronic illness is accompanied by a delay in growth and the pubertal growth spurt. The degree to which growth and pubertal development are affected in chronic illness depends upon the type of disease and individual factors, as well as on the age at illness onset, its duration and severity. The earlier its onset and the longer and more severe the illness, the greater the repercussions on growth and pubertal development. The mechanism that trigger the start of physiological puberty remain unknown. Although malnutrition is probably the most important mechanism responsible for delayed puberty, emotional deprivation, toxic substances, stress and the side effects of chronic therapy, among others, have been implicated in the pathophysiology of delayed puberty. Therefore, early diagnosis is essential and appropriate and specific therapy fundamental.
