Iron Profile in Term Small for Gestational Age Infants at 10 Weeks of Age and Correlation With Maternal Iron Profile : A Prospective Cohort Study.

BACKGROUND: Term small for gestational age (SGA) babies are at risk for developing iron deficiency anemia. The association between maternal and infant iron stores is not clear. OBJECTIVE: To assess proportion of term SGA neonates developing iron deficiency anemia by 10 weeks of age, and measure correlation between iron profile and hepcidin of babies at birth and at 10 weeks of age with maternal iron profile. DESIGN: Prospective cohort study conducted from November, 2018 to April, 2020. PARTICIPANTS: 120 term SGA babies and their mothers. INTERVENTION: Hemogram, iron profile and serum hepcidin (every fourth case) estimated in mother, cord blood and baby at 10 weeks. Babies developing anemia at 6 weeks detected by hemogram and ferritin were started on iron supplementation and excluded from the study. OUTCOME: Proportion of babies developing iron deficiency anemia at 10 weeks of age. RESULTS: 35 (29.2%) of 120 term SGA babies developed anemia (hemoglobin <9 g/dL) at 6 weeks. Proportion of infants who developed iron deficiency anemia (hemoglobin <9 g/dL and serum ferritin <40 µ/dL) at 6 and 10 weeks of age was 14.2% and 23.3%, respectively. No significant correlation was found bet-ween hemoglobin, iron and hepcidin of the baby in cord blood and at 10 weeks of age with that of mothers. Serum hepcidin in babies at birth (137.5 ng/mL) were higher than maternal values (128 ng/mL). CONCLUSION: A significant proportion of term SGA infants deve-loped anemia during early infancy, irrespective of maternal iron status.

Optimum dose of oral folic acid supplementation in transfusion-dependent thalassemia: a randomized controlled trial.

AIM AND OBJECTIVES: We compared the effect of different doses of oral folic acid (FA) supplementation (5 mg/day vs. 2.5 mg/day vs. 5 mg/week) on the proportion of children with folate excess (serum folate >20 ng/ml) and plasma homocysteine (Hcys) excess (>15 µmol/l) in transfusion-dependent thalassemia (TDT). MATERIALS AND METHODS: Children with TDT aged 5-18 years received oral FA in doses of 5 mg/day (Group 1), 2.5 mg/day (Group 2) and 5 mg/week (Group 3) for 9 months, after a wash-off period of 8 weeks. Folate levels (Serum and RBC) and plasma Hcys levels were measured after the therapy. RESULTS: Ninety children were randomized to receive one of the three interventions (30 per group). After wash-off period, the median serum folate levels were significantly lower and five children developed folate deficiency; the median [interquartile range (IQR)] serum folate levels (ng/dl) were comparable in the three groups [Group 1: 6.5 (3.3-14.2), Group 2: 5.1 (2.6-10.5) and Group 3: 4.8 (3.4-10.0)]. After 9 months of intervention, the median (IQR) serum folate levels (ng/ml) were comparable in all participants [Group 1: 18.0 (6.5-28), Group 2: 13.5 (6.4-24.5) and Group 3: 9.7 (5.3-22.5); p = 0.11]. Proportion of children with serum folate excess was 40%, 26.7% and 26.7% in Group 1, Group 2 and Group 3 (p = 0.48). Proportion of children with RBC folate excess was 92%, 86.7% and 86.7% in Group 1, Group 2 and Group 3 (p = 0.79). Hyperhomocysteinemia was seen in eight children with no significant difference between median Hcys levels in the groups (p = 0.75). CONCLUSION: Folic acid supplementation is recommended in TDT with 5 mg weekly dose being adequate.

Diagnosis, Treatment and Prevention of Nutritional Anemia in Children: Recommendations of the Joint Committee of Pediatric Hematology-Oncology Chapter and Pediatric and Adolescent Nutrition Society of the Indian Academy of Pediatrics.

JUSTIFICATION: Anemia in children is a significant public health problem in our country. Comprehensive National Nutrition Survey 2016-18 provides evidence that more than 50% of childhood anemia is due to an underlying nutritional deficiency. The National Family Health Survey-5 has reported an increase in the prevalence of anemia in the under-five age group from 59% to 67.1% over the last 5 years. Clearly, the existing public health programs to decrease the prevalence of anemia have not shown the desired results. Hence, there is a need to develop nationally acceptable guidelines for the diagnosis, treatment and prevention of nutritional anemia. OBJECTIVE: To review the available literature and collate evidence-based observations to formulate guidelines for diagnosis, treatment and prevention of nutritional anemia in children. PROCESS: These guidelines have been developed by the experts from the Pediatric Hematology-Oncology Chapter and the Pediatric and Adolescent Nutrition (PAN) Society of the Indian Academy of Pediatrics (IAP). Key areas were identified as: epidemiology, nomenclature and definitions, etiology and diagnosis of iron deficiency anemia (IDA), treatment of IDA, etiology and diagnosis of vitamin B12 and/or folic acid deficiency, treatment of vitamin B12 and/or folic acid deficiency anemia and prevention of nutritional anemia. Each of these key areas were reviewed by at least 2 to 3 experts. Four virtual meetings were held in November, 2021 and all the key issues were deliberated upon. Based on review and inputs received during meetings, draft recommendations were prepared. After this, a writing group was constituted which prepared the draft guidelines. The draft was circulated and approved by all the expert group members. RECOMMENDATIONS: We recommend use of World Health Organization (WHO) cut-off hemoglobin levels to define anemia in children and adolescents. Most cases suspected to have IDA can be started on treatment based on a compatible history, physical examination and hemogram report. Serum ferritin assay is recommended for the confirmation of the diagnosis of IDA. Most cases of IDA can be managed with oral iron therapy using 2-3 mg/kg elemental iron daily. The presence of macro-ovalocytes and hypersegmented neutrophils, along with an elevated mean corpuscular volume (MCV), should raise the suspicion of underlying vitamin B12 (cobalamin) or folic acid deficiency. Estimation of serum vitamin B12 and folate level are advisable in children with macrocytic anemia prior to starting treatment. When serum vitamin B12 and folate levels are unavailable, patients should be treated using both drugs. Vitamin B12 should preferably be started 10-14 days ahead of oral folic acid to avoid precipitating neurological symptoms. Children with macrocytic anemia in whom a quick response to treatment is required, such as those with pancytopenia, severe anemia, developmental delay and infantile tremor syndrome, should be managed using parenteral vitamin B12. Children with vitamin B12 deficiency having mild or moderate anemia may be managed using oral vitamin B12 preparations. After completing therapy for nutritional anemia, all infants and children should be advised to continue prophylactic iron-folic acid (IFA) supplementation as prescribed under Anemia Mukt Bharat guidelines. For prevention of anemia, in addition to age-appropriate IFA prophylaxis, routine screening of infants for anemia at 9 months during immunization visit is recommended.

Sunlight Exposure vs Oral Vitamin D Supplementation for Prevention of Vitamin D Deficiency in Infancy: A Randomized Controlled Trial.

OBJECTIVE: To compare the efficacy of sunlight exposure and oral vitamin D3 supplementation to achieve vitamin D sufficiency in infants at 6 months of age. DESIGN: Open-label randomized controlled trial. SETTING: Public hospital in Northern India (28.7°N). PARTICIPANT: Breastfed infants at 6-8 weeks of age. INTERVENTION: Randomized to receive sunlight exposure (40% body surface area for a minimum of 30 minutes/week) or oral vitamin D3 supplementation (400 IU/day) till 6 months of age. OUTCOME: Primary - proportion of infants having vitamin D sufficiency (>20 ng/mL). Secondary - proportion of infants developing vitamin D deficiency (<12ng/mL) and rickets in both the groups at 6 months of age. RESULTS: Eighty (40 in each group) infants with mean (SD) age 47.8 (4.5) days were enrolled. The proportion of infants with vitamin D sufficiency increased after intervention in the vitamin D group from 10.8% to 35.1% (P=0.01) but remained the same in sunlight group (13.9%) and was significant on comparison between both groups (P=0.037). The mean (SD) compliance rate was 72.9 (3.4) % and 59.7 (23.6) % in the vitamin D and sunlight group, respectively (P=0.01). The geometric mean (95% CI) serum 25(OH) D levels in the vitamin D and sunlight group were 16.23 (13.58-19.40) and 11.89 (9.93-14.23) ng/mL, respectively; (P=0.02), after adjusting baseline serum 25(OH)D with a geometric mean ratio of 1.36 (1.06-1.76). Two infants in sunlight group developed rickets. CONCLUSION: Oral vitamin D3 supplementation is more efficacious than sunlight in achieving vitamin D sufficiency in breastfed infants during the first 6 months of life due to better compliance.

Pulmonary Dysfunction in Transfusion-Dependent Thalassemia and Response to Intensive Chelation Therapy.

OBJECTIVE: To evaluate pulmonary functions in children with transfusion-dependent thalassemia, and its reversal (lung dysfunction) using intensive intravenous chelation with desferrioxamine (DFO) (4 weeks). METHODS: This descriptive study enrolled 77 children with transfusion-dependent thalassemia. Pulmonary function test (PFT) and iron load (serum ferritin (SF) and T2* MRI of heart and liver) were done. PFT included spirometry, total lung capacity (TLC) by helium dilution test and diffusion capacity by carbon monoxide (DLCO). Follow-up PFT was available for 13 children with moderate to severe lung dysfunction given intravenous DFO. RESULTS: 50 (68.8%) patients had lung dysfunction, most commonly diffusional impairment (48; 96%), and reduced TLC (11; 22%); and none had obstructive pattern. 9 (81.8%) patients with restrictive defect had moderate to severely deranged DLCO. PFT and T2* MRI values were inversely correlated with serum ferritin. Among 13 patients receiving intensive chelation for 4 weeks, significant improvement was noticed in forced expiratory volume in one minute/ forced vital capacity ratio (DFEV1/FVC) (P=0.009), DDLCO (P=0.006) and DSF (P=0.01). CONCLUSIONS: Pulmonary dysfunction is common in children with multi-transfused thalassemia, and routine screening by PFT needs to be part of the management guidelines.

Low dose depot oral vitamin D3v. daily oral vitamin D3 for treating nutritional rickets: a randomised clinical trial.

We aimed to compare the efficacy of daily v. low dose depot oral vitamin D3 for treating nutritional rickets. We conducted a randomised controlled trial in the department of paediatrics of a tertiary care hospital catering to semi-urban and rural population in Delhi, India. We randomised sixty-six children aged 3 months to 5 years with nutritional rickets to receive either daily oral vitamin D3 drops (3-12 months: 2000 IU; > 12 months to 5 years: 4000 IU; n 33) for 12 weeks duration or a single oral depot dose of vitamin D3 granules (3-12 months: 60 000 IU; > 12 months to 5 years: 150 000 IU; n 33). Participants in both groups had comparable demographic characteristics, laboratory features and radiological severity of rickets. Thirty-three participants in each group received the assigned intervention and all were followed up till 12 weeks. At 12 weeks follow-up, children in both groups showed a significant improvement in all biochemical parameters (serum Ca, P, alkaline phosphatase (ALP), parathormone and 25(OH) vitamin D levels) as well as radiological healing. At 12 weeks, the mean serum 25(OH) vitamin D levels (nmol/l) were statistically comparable in both groups (daily: 120·2 (sd 83·2), depot: 108 (sd 74), P = 0·43) and 31 (93·9 %) children in each group had radiological healing (Thacher score < 1·5). Two children in each group persisted to have raised ALP, and one child each in the daily group continued to have hypocalcaemia and hypophosphataemia at 12 weeks. Low dose oral depot vitamin D3 is an effective alternative to daily oral vitamin D3 for nutritional rickets.

Clinical Characteristics and Outcomes of Patients With Heart Failure With Reduced Ejection Fraction and Chronic Obstructive Pulmonary Disease: Insights From PARADIGM-HF.

Background Chronic obstructive pulmonary disease (COPD) is a common comorbidity in heart failure with reduced ejection fraction, associated with undertreatment and worse outcomes. New treatments for heart failure with reduced ejection fraction may be particularly important in patients with concomitant COPD. Methods and Results We examined outcomes in 8399 patients with heart failure with reduced ejection fraction, according to COPD status, in the PARADIGM-HF (Prospective Comparison of Angiotensin Receptor Blocker-Neprilysin Inhibitor With Angiotensin-Converting Enzyme Inhibitor to Determine Impact on Global Mortality and Morbidity in Heart Failure) trial. Cox regression models were used to compare COPD versus non-COPD subgroups and the effects of sacubitril/valsartan versus enalapril. Patients with COPD (n=1080, 12.9%) were older than patients without COPD (mean 67 versus 63 years; P<0.001), with similar left ventricular ejection fraction (29.9% versus 29.4%), but higher NT-proBNP (N-terminal pro-B-type natriuretic peptide; median, 1741 pg/mL versus 1591 pg/mL; P=0.01), worse functional class (New York Heart Association III/IV 37% versus 23%; P<0.001) and Kansas City Cardiomyopathy Questionnaire-Clinical Summary Score (73 versus 81; P<0.001), and more congestion and comorbidity. Medical therapy was similar in patients with and without COPD except for beta-blockade (87% versus 94%; P<0.001) and diuretics (85% versus 80%; P<0.001). After multivariable adjustment, COPD was associated with higher risks of heart failure hospitalization (hazard ratio [HR], 1.32; 95% CI, 1.13-1.54), and the composite of cardiovascular death or heart failure hospitalization (HR, 1.18; 95% CI, 1.05-1.34), but not cardiovascular death (HR, 1.10; 95% CI, 0.94-1.30), or all-cause mortality (HR, 1.14; 95% CI, 0.99-1.31). COPD was also associated with higher risk of all cardiovascular hospitalization (HR, 1.17; 95% CI, 1.05-1.31) and noncardiovascular hospitalization (HR, 1.45; 95% CI, 1.29-1.64). The benefit of sacubitril/valsartan over enalapril was consistent in patients with and without COPD for all end points. Conclusions In PARADIGM-HF, COPD was associated with lower use of beta-blockers and worse health status and was an independent predictor of cardiovascular and noncardiovascular hospitalization. Sacubitril/valsartan was beneficial in this high-risk subgroup. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT01035255.

Seven versus 10 days antibiotic therapy for culture-proven neonatal sepsis: A randomised controlled trial.

AIM: Optimal duration of parenteral antibiotics for treating neonatal sepsis ranges from 7-14 days. We compared the efficacy of 7 versus 10 days duration of intravenous antibiotics for neonatal septicaemia. METHODS: We randomised blood culture-proven septic neonates (≥32 weeks and birth weight ≥1.5 kg) to receive either 7 or 10 days duration of intravenous antibiotics. We followed up neonates upto 28 days after stopping antibiotics for treatment failure defined by reappearance of clinical sepsis with a blood culture growing the same organism as cultured earlier, or in the absence of a positive culture, the presence of C-reactive protein and as adjudicated by an expert committee. RESULTS: A total of 132 neonates were randomised to receive either 7 (n = 66) or 10 (n = 66) days duration of antibiotic therapy. Out of 128 neonates (64 per group) followed up, two (one per group) were regarded as 'treatment failure', and two were labelled as fresh episodes of sepsis (both in 10-day group). The risk (95% confidence interval) for treatment failure in the 7-day group was (1.0 (0.064-15.644) was not significantly higher. Neonates in both groups had comparable need for oxygen, inotropic support and blood products, duration of oxygen therapy and time to attainment of full feeds. The duration of hospitalisation was significantly longer in the 10-day group. CONCLUSION: A 7-day course of intravenous antibiotics may be sufficient to treat neonatal sepsis with the advantage of shorter hospital stay, but a larger meta-analysis would be required to state this with a degree of certainty.

Vitamin D Supplementation for Treatment and Prevention of Pneumonia in Under-five Children: A Randomized Double-blind Placebo Controlled Trial.

OBJECTIVE: To evaluate the efficacy of single oral mega-dose of Vitamin D3 for treatment and prevention of pneumonia in under-five children. DESIGN: Randomized, double blind, placebo-controlled trial. SETTING: Tertiary-care hospital. PARTICIPANTS: 324 children (of 980 assessed) between 6 mo-5 y age (median (IQR): 12 (7,19.8) mo) with WHO-defined severe pneumonia. Of these, 126 (39%) were vitamin D deficient (serum 25(OH)D <12 ng/mL). INTERVENTION: 100,000 IU of oral cholecalciferol (n= 162) or placebo (n= 162) in single dose, administered at enrolment. Outcome variables: Primary: Time to resolution of severe pneumonia and proportion of children having recurrence of pneumonia in next 6 months; Secondary: Change in serum levels of 25(OH)D; immunoglobulins IgA, IgG, IgM, and cathelicidin 2 weeks following supplementation; and time taken for overall resolution of illness. OUTCOME VARIABLES: Primary: Time to resolution of severe pneumonia and proportion of children having recurrence of pneumonia in next 6 months; Secondary: Change in serum levels of 25(OH)D; immunoglobulins IgA, IgG, IgM, and cathelicidin 2 weeks following supplementation; and time taken for overall resolution of illness. RESULTS: Median (95% CI) time for resolution of severe pneumonia was 30 (29, 31) h in the vitamin D group as compared to 31 (29,33) h in the placebo group [adjusted hazard ratio (95% CI): 1.39 (1.11, 1.76); P = 0.005]. The risk of recurrence of pneumonia in next 6 months was comparable in the two groups [placebo: 36/158 (22.8%); vitamin D: 39/156 (25%); RR (95% CI): 1.13 (0.67,1.90); P 0.69]. Proportion of vitamin D deficient children declined from 38% to 4% in the supplementation group, and from 41% to 33% in the placebo group, two weeks after supplementation. There was no significant effect of vitamin D supplementation on serum levels of cathelicidin, IgA and IgG. The time taken for complete recovery from pneumonia, duration of hospitalization, and fever clearance time were comparable for the two groups. No adverse event was noted related to the intervention. CONCLUSION: There is no robust evidence of a definite biological benefit, either for therapy or prevention, to suggest a routine megadose supplement of vitamin D3 for under-five children with severe pneumonia.

Oral zinc supplements are ineffective for treating acute dehydrating diarrhoea in 5-12-year-olds.

AIM: Many countries have guidelines recommending the use of oral zinc in acute dehydrating diarrhoea in children aged 2 months to 5 years of age, but no guidelines exist for older children. This study tested how effective existing recommendations are in children from 5 to 12 years of age. METHODS: Children hospitalised with acute dehydrating diarrhoea (n = 134) were randomised to receive 40 mg of oral zinc sulphate tablets or a placebo for 14 days. The primary outcome variable was the time taken for diarrhoea to stop. Secondary outcome variables included time taken for rehydration, duration of hospitalisation and recurrence of diarrhoea in the next 3 months. RESULTS: The median time for resolution of diarrhoea was 60 h in both groups. The zinc group was marginally better, but not statistically significant, for resolution (hazard ratio = 0.89, 95% CI 0.63-1.24), rehydration (hazard ratio = 0.93, 95% CI 0.66-1.32) and hospitalisation (hazard ratio = 0.94, 95% CI 0.67-1.34). The risk ratio of recurrence for zinc versus placebo (95% CI) was 0.65 [0.37-1.23] [p = 0.11]. CONCLUSION: Daily zinc supplements (40 mg for 14 days) in children aged 5-12 years with acute dehydrating diarrhoea did not shorten the duration of diarrhoea or reduce subsequent episodes. Further adequately sized, community-based trials are needed.

Energy drinks: potions of illusion.

Energy drinks are widely consumed by adolescents as these claim to improve performance, endurance and alertness. Recent reports have shown that there are no real health benefits of these drinks. On the contrary, certain adverse effects due to energy drinks have come to the forefront, casting a big question-mark on their safety and utility. This review discusses the present status of energy drinks, their active ingredients and their safety. We conclude that energy drinks, despite having some short pleasant effects, can be harmful for the body and are best avoided.

Cytokine response to dietary rehabilitation with curd (Indian dahi) & leaf protein concentrate in malnourished children.

BACKGROUND & OBJECTIVE: Protein energy malnutrition (PEM), an important cause of secondary immune deficiency, is associated with several abnormalities in the immune system including cytokine production. In the present study cytokine levels (both pro- and anti-inflammatory) were evaluated in protein energy malnourished children following nutritional rehabilitation with curd (Indian dahi) and leaf protein concentrate (LPC). METHODS: Eighty moderately and severely malnourished children, 1-5 yr of age, received the WHO recommended diet for severe malnutrition, modified according to local dietary habits, containing in addition either curd or micronutrient-rich leaf protein concentrate, for a period of 15 days. Cytokine levels [tumour necrosis factor alpha (TNFalpha), interferon gamma (IFNgamma), interleukin-10 (IL-10), interleukin-4 (IL-4)] were measured before and after dietary rehabilitation. RESULTS: The baseline cytokine levels (TNFalpha, IFNgamma, IL-10 and IL-4) were high in malnourished children. Both the diets caused an increase in serum pro-inflammatory (TNFalpha, IFNgamma), and anti-inflammatory (IL-10) cytokine levels after nutritional rehabilitation. The increase in IL-10 was significant in children receiving curd. There was an insignificant fall in IL-4 levels with both the diets. The cytokine response was comparable in children with moderate and severe malnutrition, as also in children < 2 yr to those between 2-5 yr. INTERPRETATION & CONCLUSION: The study suggests that cytokines (TNFalpha, IFNgamma, IL-10 and IL-4) may serve as biological markers to assess the effect of functional foods like curd or LPC on immunity in malnutrition. Curd may help to maintain the balance in cytokine production by increasing the production of IL-10, and may be considered in place of milk in the nutritional rehabilitation of malnourished children.

A pilot study on the effects of curd (dahi) & leaf protein concentrate in children with protein energy malnutrition (PEM).

BACKGROUND & OBJECTIVE: In protein-energy malnutrition (PEM) there is a significant impairment of immunity, both cell-mediated and humoral, which may be reversed with nutritional rehabilitation. With the use of probiotics like curd (dahi) and micronutrient-rich leaf protein concentrate (LPC), this immune recovery may be hastened. This study was conducted to assess the impact of supplementation of curd and LPC on nutritional status, and immunity as assessed by anthropometry, haemoglobin, ferritin levels, T- cell subpopulation and C-reactive protein (CRP), in children suffering from PEM. METHODS: Eighty moderate to severely malnourished children (1-5 yr) were randomized to receive either curd or LPC in addition to WHO recommended two-step diet over 15 days. Nutritional, immunological and haematological parameters were measured before and after supplementation and compared within the groups. RESULTS: The change in weight, haemoglobin level and CD4:CD8 T-cell subpopulation was significant in both the groups after supplementation. Response of CRP was blunted in PEM. Serum ferritin decreased significantly after supplementation in both groups. INTERPRETATION & CONCLUSION: Curd and LPC when added to diet of malnourished children, may have therapeutic value by accelerating immune recovery. More studies need to be done on a larger sample to confirm these findings.
