Abstract
Background: Chronic inflammation and elevated basal metabolic rate (BMR) are established features of sickle-cell anemia (SCA). However, there is little information on the possible impacts of these afore-mentioned features on glycemia and insulin sensitivity status of this group of people. Aim: This study aims to determine the insulin sensitivity status as well the effect of BMR on glycemia in adults with SCA in steady state. Materials and Methods: Fifty participants comprising 30 adults with SCA in steady state and 20 age- and gender-matched apparently healthy adults with hemoglobin genotype AA (HbAA) genotype that served as controls. Anthropometric and clinical indices were obtained using standard methods. After an overnight fast, fasting plasma glucose (FPG), and serum insulin levels were determined using the glucose oxidase method and ELISA, respectively. Indices of insulin sensitivity and β-cell function as well as BMR were appropriately calculated. Results: The mean fasting insulin resistance (IR) index, homeostatic model of assessment of IR (HOMA-IR) and of β-cell function (HOMA2-β%), and mean insulin level were significantly lower while the mean HOMA of insulin sensitivity (HOMA2-S%), quantitative insulin sensitivity check index, inverse of insulin sensitivity (1/FI), glucose-insulin ratio, C-reactive protein (CRP), and BMR was significantly higher in patients with SCA compared with the controls. The mean FPG and insulin levels and the mean values of indices of insulin sensitivity and secretion were not significantly different in SCA patients with elevated BMR compared with SCA patients with lower BMR. In addition, BMR had no significant correlation with FPG and HOMA-IR in patients with SCA. Conclusion: Despite the established chronic inflammation in SCA patients in steady state, they seem to have better insulin sensitivity status but impaired β-cell activity when compared with adults with HbAA. Furthermore, BMR does not have any pronounced effect on glycemic and insulin sensitivity status in SCA patients in steady state.

Abstract
BACKGROUND The burden of childhood obesity is increasing in most developing countries particularly in the urban areas owing to globalization; and children with sickle cell anemia (SCA) in such environment do not live in isolation. The study is aimed at determining the prevalence of obesity in younger children with SCA. METHODS A consecutive recruitment of 58 children with SCA aged between 1 year and 5 years 4 months (subjects) and their age and sex matched controls selected using multistage sampling technique were carried out. The weight and height of the children were obtained using standard equipment. The WHO Anthro and Anthro-Plus software were used for analyzing the nutritional status of the children based on standard deviation (z-scores). The data were analyzed using SPSS version 19.0 while the level of significance was set at p < 0.05. RESULTS The mean BMI for the subjects was 15.38 ± 1.93 (range from 11.50-20.80) and 17.10 ± 2.28 (range from 13.4-23.20) in the controls. Overweight (z-score > + 1 ≤ 2) and obesity (z score >+2) were recorded in 10 (17.2%) and 2 (3.4%) of the subjects while in the controls overweight and obesity were observed in 16 (27.6%) and 13 (22.4%), respectively (p = 0.000). CONCLUSIONS Obesity and overweight is becoming prevalent among children with SCA and so awareness and preventive health education about obesity should be created among caregivers of children with sickle cell anemia in our setting to avert its possible complications.

Abstract
Sickle cell anemia (SCA) is a genetic disease that affects mostly individuals of African and/or Hispanic descent, with the majority of cases in sub-Saharan Africa. Individuals with this disease show slowed growth, delayed sexual maturity, and poor immunologic function. These complications could partly be explained by the state of undernutrition associated with the disease. Proposed mechanism of undernutrition include protein hypermetabolism, decreased dietary intake possibly from interleukin-6-related appetite suppression, increased cardiac energy demand/expenditure, and increased red cell turnover. All the above mechanisms manifest as increased resting energy expenditure. Nutritional intervention utilizing single or multiple nutrient supplementation has led to improved clinical outcome, growth, and sexual maturation. Studies are currently underway to determine the best possible approach to applying nutritional intervention in the management of SCA. Management of SCA will, of necessity, involve a nutritional component, given the sociodemographic distribution of those most affected by the disease, the ease of a nutritional approach, and the wider reach that such an approach will embody.

Abstract
BACKGROUND Reduced growth is common in children with sickle cell anemia, but few data exist on associations with long-term clinical course. Our objective was to determine the prevalence of malnutrition at enrollment into a hospital-based cohort and whether poor nutritional status predicted morbidity and mortality within an urban cohort of Tanzanian sickle cell anemia patients. DESIGN AND METHODS Anthropometry was conducted at enrollment into the sickle cell anemia cohort (n=1,618; ages 0.5-48 years) and in controls who attended screening (siblings, walk-ins and referrals) but who were found not to have sickle cell anemia (n=717; ages 0.5-64 years). Prospective surveillance recorded hospitalization at Muhimbili National Hospital and mortality between March 2004 and September 2009. RESULTS Sickle cell anemia was associated with stunting (OR=1.92, P<0.001, 36.2%) and wasting (OR=1.66, P=0.002, 18.4%). The greatest growth deficits were observed in adolescents and in boys. Independent of age and sex, lower hemoglobin concentration was associated with increased odds of malnutrition in sickle cell patients. Of the 1,041 sickle cell anemia patients with a body mass index z-score at enrollment, 92% were followed up until September 2009 (n=908) or death (n=50). Body mass index and weight-for-age z-score predicted hospitalization (hazard ratio [HZR]=0.90, P=0.04 and HZR=0.88, P=0.02) but height-for-age z-score did not (HZR=0.93, NS). The mortality rate of 2.5 per 100 person-years was not associated with any of the anthropometric measures. CONCLUSIONS In this non-birth-cohort of sickle cell anemia with significant associated undernutrition, wasting predicted an increased risk of hospital admission. Targeted nutritional interventions should prioritize treatment and prevention of wasting.

Abstract
BACKGROUND Physical growth is known to be impaired in children with sickle cell disease (SCD) and the prevalence and severity vary with geographical location. The factors which contribute to this sub-optimal growth are poorly understood. OBJECTIVES To describe the growth status of children and adolescents with SCD in Yemen using the new WHO reference values and to assess correlation of growth indicators with disease severity and with haematological and biochemical parameters. METHODS A cross-sectional study of children <16 years with SCD was conducted at Al-Wahda General Teaching Hospital, Aden. Anthropometric measurements of weight, length/height, mid-upper-arm circumference (MUAC) and body mass index (BMI) were collected. Disease severity was assessed using a severity index (SI) score. RESULTS A total of 102 children (56 male) were included and their mean age was 7.2 years (range 6 months to 15 years). Low weight, height and BMI-for-age Z-scores (<-2 SD) were observed in 45%, 54% and 35% of children, respectively. Regression analyses indicated an association of low height-for-age with male gender (p=0.02), low weight-for-age and weight-for-height with increased age (both p<0.001), low weight-for-age with raised alkaline phosphatase (p=0.04), and low BMI with reduced plasma albumin (p=0.04). There was no correlation between growth deficits and SI or anaemia severity. CONCLUSION Growth is severely impaired in children and adolescents with SCD in Yemen. Growth monitoring and nutritional support should be included in their comprehensive care package.

Abstract
BACKGROUND Poor growth and under-nutrition are common in children with sickle cell disease (SCD). This review summarises evidence of nutritional status in children with SCD in relation to anthropometric status, disease severity, body composition, energy metabolism, micronutrient deficiency and endocrine dysfunction. METHODS A literature search was conducted on the Medline/PUBMED, SCOPUS, SciELO and LILACS databases to July 2007 using the keywords sickle cell combined with nutrition, anthropometry, growth, height and weight, body mass index, and specific named micronutrients. RESULTS Forty-six studies (26 cross-sectional and 20 longitudinal) were included in the final anthropometric analysis. Fourteen of the longitudinal studies were conducted in North America, the Caribbean or Europe, representing 78.8% (2086/2645) of patients. Most studies were observational with wide variations in sample size and selection of reference growth data, which limited comparability. There was a paucity of studies from Africa and the Arabian Peninsula, highlighting a large knowledge gap for low-resource settings. There was a consistent pattern of growth failure among affected children from all geographic areas, with good evidence linking growth failure to endocrine dysfunction, metabolic derangement and specific nutrient deficiencies. CONCLUSIONS The monitoring of growth and nutritional status in children with SCD is an essential requirement for comprehensive care, facilitating early diagnosis of growth failure and nutritional intervention. Randomised controlled trials are necessary to assess the potential benefits of nutritional interventions in relation to growth, nutritional status and the pathophysiology of the disease.

Abstract
BACKGROUND & AIMS Oxidative stress plays a crucial role in the sickle cell disease. Alpha-lipoic acid (ALA) is a potent antioxidant that is employed in the treatment of several diseases. The objective of this study was to test the ALA effect in the sickle cell disease (SCD) treatment. METHODS Sixty subjects were selected and divided into groups according to the hemoglobin profile: AA (normal), AS (SCD trait subject) and SS (SCD patient). Patients were randomized into a placebo-controlled trial and treated with either ALA (200 mg) or vehicle. Blood samples were collected before supplementation and after 3 months of treatment. Catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx) activities and total antioxidant status (TAS) were evaluated as measure of antioxidant defense. Lipid and protein damages were quantified by malondialdehyde (MDA) and carbonyl assays, respectively. RESULTS CAT activity significantly increased in the AS group after ALA treatment and GPx activity presented significant decrease in all groups. SOD activity was not different in any group. Data on MDA and carbonyl levels showed significant reduction in the AA group with ALA treatment. TAS decreased in the same group. CONCLUSION ALA treatment protected AA individuals from oxidative damage to lipids and proteins. In SCD subjects, the dose applied was not effective to prevent the oxidative damage.

Abstract
As part of a larger study that examined pain experience, pain management, and pain outcomes among children with sickle cell disease, functional status (sleep, food intake, and activity levels) was examined during hospitalization for acute painful episodes. Children were asked to rate the amount of pain they experienced as well as the amount of time they slept, the amount of food they ate, and the amount of activity they had everyday. Children reported high levels of pain, which showed only a small decrease throughout hospitalization, and had disrupted sleep and wake patterns, decreased food intake, and decreased activity levels. Nurses need to routinely monitor functional status during acute painful episodes so that strategies to promote adequate sleep, food intake, and activity may be incorporated to minimize long-term negative outcomes in children with sickle cell disease.
