Breast feeding and protection against neonatal sepsis in a high risk population.

Protection against neonatal sepsis by breast feeding was investigated in a developing community. A case-control study was carried out with 42 cases from a hospital and 270 controls, matched for age and socioeconomic conditions from the community. Exclusive breast feeding was extremely rare, most babies being partially breast fed and a few being given formula feed or animal milk. A highly significant odds ratio of 18 was obtained, showing that even partial breast feeding protects against neonatal sepsis in such a population.

Folate, vitamin B12, and homocysteine levels in South Asian women with growth- retarded fetuses

Objective.  To investigate whether intrauterine growth retardation (IUGR) and preterm delivery in a poor population of South Asia was associated with altered maternal and fetal levels of folate, vitamin B12, and homocysteine.

Cytokines in the Placenta of Pakistani Newborns With and Without Intrauterine Growth Retardation

Although intrauterine growth retardation (IUGR) is a major risk factor for increased neonatal mortality and morbidity, the mechanisms behind it are not clear. We analyzed cytokine gene expression and gene polymorphisms in infants with and without IUGR in Pakistan, where IUGR is very common. 45 IUGR and 55 control mother/infant pairs were studied. mRNA for IL-10, IL-8, TNF-α, TGF-β, IL-6, IL-4, IL-1β, IL-12, IFN-γ and GAPDH was quantified with RT-PCR from placenta. Cytokine and cytokine receptor gene polymorphisms for -1087IL10, -308TNFA, -174IL6, +915TGFB1, intron 2 IL1RN, +36TNFR1, 150V IL4RA and -159CD14 were determined from genomic DNA. The serum levels of IL-1β, IL-6, IL-8, IL-10, IL-12, TNF-α and TGF-β were measured.There was a significant decrease of IL-10 and IL-12, but increase of TGF-β in the decidua and similarly decrease of IL-10, but increase of TGF-β in the trophoblasts of the IUGR placentas compared with the non-IUGR placentas. We found significantly lower levels of IL-1β in serum from the mothers of the IUGR infants and of TGF-β in serum of the infants with IUGR compared with the non-IUGR infants. We note that the IL-10 mRNA expression in the decidua was down-regulated, but the TGF-β mRNA up-regulated in IUGR placentas of mothers from a population with multiple risk factors for IUGR. We propose that the low IL-10 in the placenta may be involved in the pathogenesis of IUGR and might possibly be treatable.

Feeding patterns diarrhoeal illness and linear growth in 0-24-month-old children.

The aim was to study the impact of simple healthcare interventions in 0-24-month-old children living in rural communities outside Lahore, Pakistan. Newborns belonging to four birth cohorts were followed monthly from 0-24 months of age living in rural communities. Three cohorts were from the same village: Cohort A (1984-1987), n = 485; Cohort B (1990-1992), n = 544; and Cohort C (1995-1997), n = 518. A fourth, Cohort D, was from neighbouring villages (1995-1997), n = 444. Findings from Cohort A formed the basis of a healthcare programme, including promotion of optimal breastfeeding practices, advice on oral rehydration therapy, and continued feeding during diarrhoea. The outcome measures studied were time of initiation of breastfeeding, feeding of prelacteals, exclusive breastfeeding, diarrhoeal illnesses, and postnatal linear growth. The median time of initiation of breastfeeding decreased from 47 to 3 h and exclusive breastfeeding increased from 5 per cent in Cohort A to more than 80 per cent in the subsequent cohorts, at 1 month of age. No prelacteals were given to 34 per cent of newborns in later cohorts compared with 100 per cent in Cohort A. Diarrhoeal illnesses during the first 6 months had reduced significantly. Postnatal linear growth improved by about 3 cm in the later cohorts. Appropriate changes in breastfeeding practices through integrated and focused healthcare, especially antenatally, can reduce diarrhoeal illnesses, and sustain and improve linear growth in young children.

Antisecretory factor effectively and safely stops childhood diarrhoea: a placebo-controlled, randomised study

We studied the response to high doses of egg yolk containing antisecretory factor (B221®, Salovum®) in young children with acute diarrhoea, presenting to the Childrens Hospital, Lahore, Pakistan.

Early-life Risk Factors for Adult Chronic Disease: Follow-up of a Cohort Born During 1964-1978 in an Urban Slum of Lahore, Pakistan

Evidence suggests that risk of chronic diseases may be programmed during the foetal and early life of the infant. With high rates of low birthweight coupled with a rapid nutritional transition, low-income countries are facing an epidemic of chronic diseases. Follow-up of a cohort of adults born during 1964–1978 in an urban slum in Lahore, Pakistan, is presented in this paper. In 695 of these adults (mean age=29.0 years, males=56%), blood pressure, fasting blood glucose, and body mass index (BMI) were measured to assess early-life predictors of risk of chronic diseases. Sixteen percent of the study population was born with a low birthweight (<2,500 g). A significant positive association (p=0.007) was observed between birthweight and BMI; additionally, adjusting for age and gender, the association with BMI was highly significant (p=0.000). Conversely, a significant negative association (p=0.016) was observed between birthweight and adult levels of fasting plasma glucose; after adjustment for age and gender, the association was more significant (p=0.005) No association was observed between birthweight and adult blood pressure. The results suggest that low birthweight may increase later risk of impaired glucose tolerance in urban Pakistani adults. Further research in this area is warranted.

Growth and Nutrition: The First Six Months

Today the WHO Growth Chart Standards, based on the growth of breastfed infants, are used. These growth curves solve the problem of the deviating observations for breastfed compared to non-breastfed infants using previous growth charts. Presently it is not clear how the mothers diet, especially the fat intake, influences the growth of the offspring. Animal experiments indicate that a low intake of n-3 polyunsaturated fatty acids via the milk may have short- and long-term negative consequences. There is limited information in man. It has been suggested that the mammary glands may have phylogenetically originated from glands providing innate immunity, later developing capacities for providing nutrition. This would agree with the fact that human milk contains so many major components which do not primarily function as nutrients, but seem to protect nutrition and growth. Lactoferrin, oligosaccharides, glycoproteins, secretory IgA antibodies, alpha-lactalbumin and the antisecretory factor have such functions.
