A cross-sectional study evaluating the prevalence and predictors of malnutrition among children and adolescents visiting an urban academic hospital in Nepal

OBJECTIVE

To examine the prevalence of malnutrition among children and adolescents visiting Kanti Children’s Hospital (KCH) and identify predictors associated with malnutrition. Results will guide the development of a newly established nutrition programme at KCH.

DESIGN

This cross-sectional pilot study recruited children and adolescents over a 1-month period. Nutritional anthropometrics (height, weight and mid-upper arm circumference (MUAC)) and socio-demographic questionnaires were administered. Clinical data were abstracted from the medical chart.

SETTING

KCH in Kathmandu, Nepal.

PARTICIPANTS

370 children and adolescents.

RESULTS

Most participants were male (65·1 %); mean age was 3·9 years (±3·4 years). The prevalence of stunting was 25·9 %, wasting was 17·3 % and 24·0 % when classified by BMI-for-age Z-score or MUAC, respectively. Two percent of participants were overweight. Notably, 32·1 % of children ≥5 years were classified with wasting based on MUAC-for-age Z-score, which is higher than that observed in children <5 (20·2 %). Food insecurity was reported among 58·2 % of children with stunting and 34·0 % with wasting. Chronic medical conditions predicted stunting and wasting. The lowest level of wealth predicted stunting, while ethnicity predicted wasting. Ethnicity and education level predicted food insecurity.

CONCLUSIONS

We found that the prevalence of stunting and wasting at KCH are higher than previously published studies in Nepal. Malnutrition persists beyond 5 years, and we identified several predictors of malnutrition. Increased provision of and access to clinical nutrition programmes is an essential need for KCH. Twinning programs that provide local clinicians with increased opportunities for education and mentorship of local staff remains a pressing need in Nepal.

Abstract 5216: The effect of polymorphisms in DAT1 and DRD4 on dietary intake during chemotherapy for childhood leukemia

Outcomes of acute lymphoblastic leukemia (ALL) are associated with both host and environmental factors. We hypothesized that there is also an interaction between them, with genetic variants influencing dietary choices. The dopamine transporter 1 (DAT1) and D4 subtype of the dopamine receptor (DRD4) genes are polymorphic, with a variable number of nucleotide repeats (VNTR) that affect dopaminergic neurotransmission, and reward circuitry for food cravings. Specifically, the 9-tandem repeats (9R) allele of DAT1 and the 7-tandem repeats (7R) allele of DRD4 are risk factors for eating disorders or undereating behavior in children. The goal of this study was to determine whether these polymorphisms are associated with altered dietary intake during therapy for childhood ALL. DNA was isolated from peripheral blood mononuclear cells collected from 439 children being treated on Dana Farber Cancer Institute ALL Consortium Protocol 05-001 (NCT00400946). Target alleles in DAT1 and DRD4 were determined using PCR product length analysis. Each subject was classified as having either zero or at least one copy of the target alleles. Dietary intake was previously determined using food frequency questionnaires collected at three timepoints: time of diagnosis, end of induction, and continuation therapy. As previously published dietary composition in fat and carbohydrate differed significantly among three timepoints. There was no significant difference between those with or without the target alleles in DAT1 or DRD4 in percent from fat or percent from carbohydrate at any of the three timepoints. However, significant differences were observed when dietary intake was compared to the Dietary Reference Intake (DRI). Notably, a greater portion of male participants with DAT1 9R polymorphism had fat consumption below the DRI at the time of diagnosis. On the contrary, significantly decreased portion of females with DAT1 9R had fat consumption below the DRI during continuation therapy. When compared to normative values, a significantly increased number of children had total calorie consumption below DRI during induction therapy. The DRD4 7R polymorphism was associated with fat intake below DRI during induction therapy in males. However, neither DAT1 nor DRD4 polymorphisms were related to variation in carbohydrates consumption. In addition, a greater portion of participants that carry both DAT1 and DRD4 polymorphism exhibited a trend toward undereating behavior in fat intake compared to the controls. Our results are the first to indicate that DAT1 and DRD4 polymorphisms are associated with altered dietary intake during chemotherapy for childhood ALL. Future study will further elucidate whether this modulation is associated with changes in their body weight, BMI, glucose level, and disease relapse.

Vitamin A and association with asparaginase-associated pancreatitis in children with acute lymphocytic leukemia

10021

Background: Asparaginase is a key component of treatment of acute lymphoblastic leukemia (ALL), which is the most common cancer in the pediatric population. However, asparaginase is associated with many toxicities, including pancreatitis, which is observed in up to 10% of patients and can lead to severe sequelae. Methods: We performed analysis of (1) transcriptomic data from (a) asparaginase-treated leukemic cells, and (b) the pancreas of mice that were induced with a chemical form of pancreatitis; (2) the US FDA Adverse Reporting System (FAERS) and electronic health records (TriNetX); (3) global plasma metabolomic screen and dietary intake evaluation from ALL patients; and (4) experimental animal studies to identify factors that impact asparaginase-associated pancreatitis (AAP). Results: Connectivity map analysis showed that asparaginase-induced gene signatures are potentially reversed by the retinoids (vitamin A and its natural and synthetic analogs). Analysis of TriNetX and FAERES demonstrated a 2-fold reduction in AAP risk with concomitant exposure to vitamin A. Further, we performed a case-control metabolomic study of 50 subjects with ALL enrolled in the Dana-Farber Cancer Institute DFCI ALL clinical trial protocols 05-001 (NCT00400946) and 11-001 (NCT01574274). All subjects were given a single dose of pegylated E. Coli asparaginase during induction therapy. Twenty-four subjects developed pancreatitis within 9 months from the start of induction therapy and were considered cases. The median time to develop pancreatitis among cases was 3.68 months (interquartile range: 3.58 months). Twenty-six control subjects were identified among patients who did not develop pancreatitis within the same evaluation period. The controls were matched for age, sex, and initial ALL risk. The screening revealed that the plasma levels of carotene diol isomers, from the start of induction to its end, were reduced by about 60% in the cases compared to the controls. A detailed 30-day dietary recall showed that the cases had received less dietary vitamin A than the controls during induction therapy. Notably, the median value for the composite intake of vitamin A constituents, termed the RAE (retinol activity equivalents) was 656.92 mcg per day among the controls, but was 34.6% lower among in the cases (median of 429.40 mcg per day, which is just above the recommended dietary allowance level of 400 mcg per day for the 4–8 year-old age group). In mice, asparaginase administration as a single agent was sufficient to reduce circulating and hepatic retinol levels. Conclusions: Based on these data, we propose that circulating retinoids maintain pancreatic health, that asparaginase reduces circulating retinoids, and AAP is more likely to develop with reduced dietary vitamin A intake. The systems approach provides the impetus to examine the role of dietary vitamin A supplementation for preventing or treating AAP.

Efficacy of ready-to-use therapeutic food in malnourished children with cancer: Results of a randomized, open-label phase 3 trial

BACKGROUND

The adverse influence of undernutrition in children with cancer may be remediated by early nutritional intervention. This study assessed the efficacy of ready-to-use therapeutic food (RUTF) in improving nutritional status and reducing treatment-related toxicities (TRTs) in such children.

METHODS

In a randomized controlled phase-3 open-label trial, severely and moderately undernourished children with cancer were randomized 1:1 to receive standard nutritional therapy (SNT) or SNT+RUTF for 6 weeks. The primary outcome (weight gain >10%) and secondary outcomes (improved/maintained nutritional status, improved body composition) were assessed after 6 weeks. TRTs were assessed over 6 months.

RESULTS

Between July 2015 and March 2018, 260 subjects were enrolled, 126 were analyzable in both arms at 6 weeks. More children on RUTF had weight gain (98 [77.8%] vs. 81 [64.2%], p = .025) with a greater increase in fat mass as a percentage of body mass (median 2% [IQR -0.12 to 4.9] vs. 0.5% [IQR -1.45 to 2.27, p = .005]) but a greater loss of lean mass (median -1.86% [IQR -4.4 to 0.50] vs. -0.4% [IQR -2.4 to 1.4, p = .007]) compared to the SNT arm. Fewer subjects on the RUTF arm had episodes of severe infection (10.6% vs. 31%, p < .0001), treatment delays (17.7% vs. 39%, p < .0001), and severe mucositis (11% vs. 23.8%, p = .006) compared to the SNT arm. The odds of developing TRTs on the RUTF arm were lower even after adjusting for improvement in nutritional status.

CONCLUSIONS

RUTF is efficacious in improving weight gain and nutritional status in undernourished children with cancer and decreases TRTs. Incorporating RUTF into a healthy, balanced diet should be considered in undernourished children with cancer.

Nutritional status at diagnosis of cancer in children and adolescents in Guatemala and its relationship to socioeconomic disadvantage: A retrospective cohort study

BACKGROUND

At least 80% of children with cancer live in low- and middle-income countries where the prevalence of malnutrition and socioeconomic disadvantage is high. We examined the relationship between nutritional status (NS), assessed by arm anthropometry, and socioeconomic status (SES) in children diagnosed with cancer at Unidad Nacional de Oncologia Pediatrica (UNOP) in Guatemala over a three-year period.

METHOD

Patients aged 0 to 18 years of age diagnosed between January 2015 and December 2017 were included. NS was evaluated by mid-upper arm circumference, triceps skin fold thickness, and serum albumin level, and subjects were classified as adequately nourished, moderately depleted, and severely depleted nutritionally. SES was measured by a 15-item instrument developed at UNOP.

RESULTS

Of 1365 patients diagnosed in the study period, 1060 (78%) fulfilled the eligibility criteria. Only 6% of patients were classified as medium to high, the remainder as medium-low to extremely low SES. Almost 47% were severely depleted at diagnosis, 19% moderately depleted, and 34% adequately nourished. SES was shown to be a determinant of NS; with progressively lower SES, the probability of a decline in NS increased by a factor of 1.04 points (P < 0.0001). Leukemia and lymphoma were also important predictors of nutritional depletion with odds ratios of 6.08 (95% CI, 1.74-28.28; P = 0.008) for leukemias and 4.83 (95% CI, 1.33-23.03; P = 0.03) for lymphomas.

CONCLUSION

Both low SES and a diagnosis of leukemia or lymphoma are strong predictors of poor NS at diagnosis in children with cancer in Guatemala.

Highlights from the 13th African Continental Meeting of the International Society of Paediatric Oncology (SIOP), 6-9 March 2019, Cairo, Egypt

The 13th African continental meeting of the international society of paediatric oncology, held on 6-9 March 2019 in Cairo, was organised in collaboration with the Children Cancer Hospital (57357) in Egypt and the global parents' organisation (Childhood Cancer International) and supported by a large international faculty. With 629 delegates from 37 countries (24 African), this was the largest forum of healthcare professionals focused on children and young people with cancer in Africa to showcase advances and discuss further improvements. Three targeted workshops, on nursing care, pharmacy and nutrition, attracted large numbers and catalysed new collaborative initiatives in supportive care studies, extended roles for pharmacists in quality control and care delivery and addressed malnutrition concurrently with cancer treatment. The Collaborative Wilms Tumour Africa Project, open in seven sub-Saharan countries, and the trials in Burkitt's lymphoma reported encouraging outcomes with further initiatives in supportive care (the supportive care for children with cancer in Africa project). While acknowledging deficits in radiotherapy provision, available in only 23 of 52 African countries, centres with facilities reported their technical advances that benefit patients. Of great importance for children with brain tumours, who are underdiagnosed in Africa, was the first announcement of African paediatric neuro-oncology society, whose 63 current members aim to tackle the shortage of neurosurgeons through training fellowships, workshops and a dedicated conference. The congress provided the opportunity to discuss how African countries will work with the WHO global initiative aiming to improve childhood cancer survival to 60% in all countries by 2030. This conference report is dedicated to the three Kenyan delegates who died tragically on the Ethiopian Airlines flight ET302 on their way home, full of new ideas and pride in what they had achieved so far. All those who heard their presentations are determined to continue their excellent work to improve cancer care for children in Africa.

Burkitt lymphoma – Nutritional support during induction treatment: Effect on anthropometric parameters and morbidity of treatment

Background: Malnutrition is common in children diagnosed with cancer in Africa, and it adds to the morbidity and mortality of treatment. Nutritional support is known to reduce morbidity and mortality of treatment.Aim: The aim of this study was to record changes in anthropometric parameters, morbidity and mortality in patients admitted with Burkitt lymphoma (BL) whose diet was supplemented with protein, vitamins and minerals during induction chemotherapy.Methods: Seventy consecutive newly diagnosed BL patients were enrolled. The diet was supplemented with a daily egg, 200 mL F-75 formula and vitamins. Guardians received 3 cups of dry rice and $1 daily to buy and prepare meals for the patient and themselves whilst in the hospital. Height, weight, triceps skinfold (TSF) and mid-upper arm circumference (MUAC) were recorded on days 1 and 28. Co-morbidities at diagnosis were treated, and neutropenia and febrile episodes managed with a standard protocol. Two patients who died within 24 h after admission were excluded from the anthropometric analyses.Results: The mean age was 8 (range 2–16) years and the male:female ratio was 42:28. The St Jude stage distribution was as follows: Stage I = 6%, II = 4%, III = 69%, IV = 21%. Weight for age was < 10th centile at diagnosis in 18% (but influenced by tumour mass). Weight was unchanged or increased by ≥ 5% in 66% of patients on Day 28. The TSF was < 3rd centile in 47% of patients and increased by ≥ 0.5 cm in 57%. The MUAC was < 3rd centile in 16% of patients at diagnosis and in 10% of patients on Day 28. Febrile episodes in 60% and neutropenia in 18% of patients were successfully treated. Two patients died from presumed renal failure. The overall death rate (including the two deaths within 24 h after admission before chemotherapy was started) was 5.5% (n = 4).Conclusion: The TSF improved in the majority and the MUAC improved in some patients. Febrile neutropenia and febrile episodes could be successfully managed. The death rate during induction was lower than in our previously published results with the same chemotherapy protocol. Dietary supplementation should be a standard component of treatment in paediatric patients with cancer.

Impact on survival and toxicity by duration of weight extremes during treatment for pediatric acute lymphoblastic leukemia: A report from the Children's Oncology Group

PURPOSE

Previous studies regarding the influence of weight on event-free survival (EFS) and treatment-related toxicity (TRT) in childhood acute lymphoblastic leukemia (ALL) considered only weight at diagnosis. Inasmuch as weight varies substantially over treatment, we hypothesized its impact on EFS is instead determined by cumulative time spent at an extreme weight during therapy and on TRT by weight at the time of toxicity.

PATIENTS AND METHODS

In a cohort of 2,008 children treated for high-risk ALL in Children's Oncology Group study CCG-1961, we determined the effect on EFS of cumulative time receiving therapy at an extreme weight (either obese or underweight) between end of induction and start of maintenance therapy. We also evaluated the association between weight category and incidence and patterns of TRT during 13,946 treatment courses.

RESULTS

Being obese or underweight at diagnosis and for ≥ 50% of the time between end of induction and start of maintenance therapy resulted in inferior EFS (hazard ratios, 1.43 and 2.30, respectively; global P < .001). Normalization of weight during that period resulted in mitigation of this risk comparable to never being obese or underweight. Obese or underweight status at start of each treatment course was significantly associated with specific patterns of TRT.

CONCLUSION

Influence of weight extremes on EFS and TRT is not set at diagnosis as previously reported but is moderated by subsequent weight status during intensive postinduction treatment phases. These observations suggest that weight is a potentially addressable risk factor to improve EFS and morbidity in pediatric ALL.

A phase I dose-finding study of silybin phosphatidylcholine (milk thistle) in patients with advanced hepatocellular carcinoma

PURPOSE

To determine the maximum tolerated dose per day of silybin phosphatidylcholine (Siliphos) in patients with advanced hepatocellular carcinoma (HCC) and hepatic dysfunction.

EXPERIMENTAL DESIGN

Patients with advanced HCC not eligible for other therapies based on poor hepatic function were enrolled in a phase I study of silybin phosphatidylcholine. A standard phase I design was used with 4 planned cohorts, dose escalating from 2, 4, 8, to 12 g per day in divided doses for 12 weeks.

RESULTS

Three participants enrolled in this single institution trial. All enrolled subjects consumed 2 g per day of study agent in divided doses. Serum concentrations of silibinin and silibinin glucuronide increased within 1 to 3 weeks. In all 3 patients, liver function abnormalities and tumor marker α-fetoprotein progressed, but after day 56 the third patient showed some improvement in liver function abnormalities and inflammatory biomarkers. All 3 participants died within 23 to 69 days of enrolling into the trial, likely from hepatic failure, but it could not be ruled out that deaths were possibly due to the study drug.

CONCLUSION

Short-term administration of silybin phosphatidylcholine in patients with advanced HCC resulted in detectable increases in silibinin and its metabolite, silibinin glucuronide. The maximum tolerated dose could not be established. Since patients died soon after enrollment, this patient population may have been too ill to benefit from an intervention designed to improve liver function tests.

Children's Oncology Group's 2013 blueprint for research: cancer control and supportive care

In cancer control research, the objective is to reduce overall morbidity and mortality by decreasing acute and delayed treatment-related toxicities in all children with cancer. To date, the Children's Oncology Group (COG) has focused on infection, neurocognition, quality of life (QoL), and nutrition/antiemetics. COG is conducting randomized controlled trials (RCTs) to determine prophylaxis strategies that will reduce infections in high-risk populations. Two RCTs are determining if modafinil or computerized cognitive training improve cognitive functioning in pediatric brain tumor patients. QoL is being assessed in acute leukemia patients. Improved supportive care outcomes will only occur when the most effective interventions are established.

Clinical applications of Silybum marianum in oncology

Milk thistle (Silybum marianum) is an herb that is increasingly used in oncology research and treatment settings. Historically, it has been used to treat liver and biliary disorders and has been used in detoxification and cleansing protocols. However, milk thistle is increasingly being investigated for its use in adult and pediatric populations for oncology indications. Possible indications during cancer treatment include cleansing and detoxification after chemotherapy, preventing hepatotoxicity during chemotherapy, treating hepatotoxicity after chemotherapy, and potentiating chemotherapy and radiation therapy as an adjunctive treatment. Milk thistle may also have applications in ameliorating long-term hepatic and cardiovascular effects of cancer treatment. Preliminary studies are investigating its use as a chemopreventive agent and possibly to treat cancer directly. Much of milk thistle's current clinical use grows out of historical uses but is informed by an increasing number of clinical trials and animal studies. This article provides an overview of the current clinical applications of milk thistle in the oncology setting, including guidelines on commonly used forms and doses.
