Assessment of some micronutrients serum levels in children with severe acute malnutrition with and without cerebral palsy- A follow up case control study

Micronutrient supplementation practices in relation to the World Health Organisation 2013 guidelines on management of severe acute malnutrition

In 2013, the World Health Organisation (WHO) updated the recommendations for micronutrient deficiency correction in hospitalised under-5 children with complicated severe acute malnutrition (SAM). This study aimed to describe the micronutrient deficiency correction practices in relation to WHO 2013 recommendations. Data from medical records of under-5 children admitted for SAM management at two hospitals in South Africa and three tertiary hospitals in Ghana were extracted. Micronutrient correction practices were compared to the WHO 2013 recommendations by considering the dosage, timing of micronutrient supplementation (vitamin A, iron and folic acid) and therapeutic feeds administered. In total, 723 medical records were included. Nearly half (48.3%) of the children received at least one of the studied micronutrients as a supplement. Vitamin A was supplemented in 27.4% of the children, while iron and folic acid were supplemented in 9.5% and 34.9%, respectively. Among the children who received vitamin A, 60.1% received the first dose on Day 1 of admission. Also, 46.4% of the iron-supplemented children received iron within the first week of admission. Vitamin A, iron and folic acid were administered within the dose range of 100,000-180,000 IU, 3.1-7.7 mg per kg per day, and 3-5 mg per day, respectively. Additionally, 71.7% of the children reportedly received therapeutic feeds that met WHO recommendations. The micronutrient deficiency correction practices regarding dose and timing differed from the 2013 WHO guidelines. Qualitative studies investigating the reasons for the disparities are recommended.

Micronutrient status in children aged 6-59 months with severe wasting and/or nutritional edema: implications for nutritional rehabilitation formulations

Undernutrition remains a global struggle and is associated with almost 45% of deaths in children younger than 5 years. Despite advances in management of severe wasting (though less so for nutritional edema), full and sustained recovery remains elusive. Children with severe wasting and/or nutritional edema (also commonly referred to as severe acute malnutrition and part of the umbrella term "severe malnutrition") continue to have a high mortality rate. This suggests a likely multifactorial etiology that may include micronutrient deficiency. Micronutrients are currently provided in therapeutic foods at levels based on expert opinion, with few supportive studies of high quality having been conducted. This narrative review looks at the knowledge base on micronutrient deficiencies in children aged 6-59 months who have severe wasting and/or nutritional edema, in addition to highlighting areas where further research is warranted (See "Future Directions" section).

Malnutrition and nutritional deficiencies in children with cerebral palsy: a systematic review and meta-analysis

OBJECTIVES

This systematic review study and meta-analysis sought to estimate the prevalence of malnutrition and nutritional deficiencies in children with cerebral palsy (CP).

STUDY DESIGN

This is a systematic review and meta-analysis.

METHODS

The systematic review was conducted according to the PRISMA guidelines. The articles were chosen using the PubMed, Embase, Scopus, Web of Science, Cochrane Library, SciELO, and Lilacs databases and the bibliographical reference lists of the articles. No limitations were placed on the time of publication, but the articles had to include children from 0 to 18 years old with CP who presented the prevalence of malnutrition and nutritional deficiencies. The methodological quality of the articles was assessed using the verification list for analytical cross-sectional studies, the Newcastle-Ottawa scale, and the Cochrane Collaboration tool for randomized studies. The meta-analysis of proportions was conducted based on the prevalence data for malnutrition or nutritional deficiencies. The study is registered in PROSPERO under CRD number 42020175068.

RESULTS

Sixty-seven articles (N = 453,804) published between 1986 and 2019 were included. Most of the articles presented a low risk of bias and no publication was excluded for quality reasons. The most widely used anthropometric index for diagnosing nutritional status was weight-to-age and the estimated prevalence of malnutrition was 40% (95% CI = 28.0-53.0). Nutrient deficiency was investigated by nine publications, with hypocalcemia and reduced serum concentrations of zinc, copper, and vitamin D being reported the most.

CONCLUSIONS

We found a high rate of malnutrition in the population in this review, moreover, we suggest that some nutritional deficiencies are associated with food deficit and that the socio-economic and age factors of these children may relate with the poor nutritional outcome. This makes monitoring and personalized nutritional management necessary, in accordance with the characteristics and particularities of children with CP.

Serum trace element and amino acid profile in children with cerebral palsy

BACKGROUND

The existing data demonstrate that both trace elements and amino acids play a significant role in neurodevelopment and brain functioning. Certain studies have demonstrated alteration of micronutrient status in children with cerebral palsy, although multiple inconsistencies exist.

THE OBJECTIVE

of the present study was to assess serum trace element and mineral, as well as amino acid levels in children with cerebral palsy.

METHODS

71 children with cerebral palsy (39 boys and 32 girls, 5.7 ± 2.3 y.o.) and 84 healthy children (51 boys and 33 girls, 5.4 ± 2.3 y.o.) were enrolled in the present study. Serum trace element and mineral levels were assessed using inductively-coupled plasma mass-spectrometry (ICP-MS). Amino acid profile was evaluated by means of high-pressure liquid chromatography (HPLC).

RESULTS

Children with cerebral palsy are characterized by significantly lower Cu and Zn levels by 6% and 8%, whereas serum I concentration exceeded the control values by 7%. A tendency to increased serum Mn and Se levels was also observed in patients with cerebral palsy. Serum citrulline, leucine, tyrosine, and valine levels were 15 %, 23 %, 15 %, and 11 % lower than those in healthy controls. Nearly twofold lower levels of serum proline were accompanied by a 44 % elevation of hydroxyproline concentrations when compared to the control values. In multiple regression model serum I, Zn, and hydroxyproline levels were found to be independently associated with the presence of cerebral palsy. Correlation analysis demonstrated a significant correlation between Cu, Mn, Se, I, and Zn levels with hydroxyproline and citrulline concentrations.

CONCLUSION

The observed alterations in trace element and amino acid metabolism may contribute to neurological deterioration in cerebral palsy. However, the cross-sectional design of the study does not allow to estimate the causal trilateral relationships between cerebral palsy, altered trace element, and amino acid metabolism.

The Impact of Malnutrition on Hospitalized Children With Cerebral Palsy

Children with cerebral palsy (CP) and other medical complexity comprise an outsized proportion of health care use. In this review, we describe the current science of assessment of nutritional status for children with CP, outline a systematic approach to assessing their nutritional status, delineate ramifications of malnutrition on hospitalization-associated outcomes, and identify knowledge gaps and means of addressing those gaps using quality improvement and clinical research tools. Methods to accurately assess body composition and adiposity in this population by using skinfolds, age, sex, and activity level are available but are not widely used. There are limitations in our current method of estimating energy needs in children with CP, who are at higher risk of both obesity and micronutrient deficiencies. There is some evidence of an association between malnutrition, defined as either underweight or obesity, and hospitalization-associated outcomes in children generally, although we lack specific data for CP. The gaps in our current understanding of optimal nutritional status and between current science and practice need to be addressed to improve health outcomes for this vulnerable patient population.

A Case-Control Study of Essential and Toxic Trace Elements and Minerals in Hair of 0-4-Year-Old Children with Cerebral Palsy

The objective of the present study was to assess hair essential and toxic trace elements and minerals in children with cerebral palsy in relation to age of the examinees. A total of 70 children with cerebral palsy and 70 healthy controls aged 0-4 years old were enrolled in the present study. The examined children were also divided into two age groups of those younger and older than 2 years old. Hair trace element content was assessed using ICP-MS at NexION 300D (PerkinElmer, USA). The obtained data demonstrate that hair boron was more than 2-fold lower in CP children as compared with the control group. At the same time, hair Na, Se, and V levels were 21%, 12%, and 20% lower when compared with healthy controls, respectively. It is also notable that a 9% and 28% decrease in hair Fe and Li levels respectively were nearly significant. The observed alterations were more profound in a younger group of patients. No significant group difference in hair toxic metal and metalloid levels was observed between the general cohorts of children with and without CP. In regression models, only hair Al and Ca contents were significantly associated with the presence of cerebral palsy, whereas hair Mg, Na, Ni, and Se levels were characterized as significant negative predictors. The observed alteration in trace element metabolism may also provide an additional link between cerebral palsy, psychomotor delay, and certain diseases, including diabetes, epilepsy, and osteoporosis. However, further studies using other substrates (blood, urine) or biomarkers are required.
