Nutritional Support for Lactating Women and Azithromycin to Infants - Mumta Lactating Women Trial

A community-based, randomized control, assessor blinded trial in peri-urban settings of Karachi, Pakistan to study the impact of Lipid-based Nutritional Supplement for Pregnant and Lactating women which is balanced energy-protein (BEP) dietary supplement, a locally produced ready-to-use nutritional product for lactating women (LW) and single prophylaxis dose of Azithromycin for infants, on growth of infants over the period of six months since birth compared to current standard of care. LW and her infant will be enrolled in the trial within 168 hours of the birth and LW will be randomized in either of the arm:

1. Arm A: 'Control Arm', LW will only receive standard of care which comprises of standard nutritional counseling, key messages of exclusive breastfeeding, essential newborn and infant care and immunization. 2. Arm B: 'Nutritional supplement only', LW randomized will recieve nutrition supplement product for next 6 months to be consumed in a dose of 2 sachets of 75 grams per day. Further, LW will also receive standard of care which comprises of standard nutritional counseling, key messages of exclusive breastfeeding, essential newborn and infant care and immunization. 3. Arm C: ''Nutritional supplement plus Azithromycin', LW randomized will receive nutritional supplement product for next 6 months to be consumed in a dose of 2 sachets of 75 grams per day. Further, the infant of LW will receive a single dose of Azithromycin (20mg/kilogram) at day 42 of age. Further, LW will also receive standard of care which comprises of standard nutritional counseling, key messages of exclusive breastfeeding, essential newborn and infant care and immunization.

Study aim is to assess the efficacy of nutritional product in a proposed dose to lactating women for at least 6 months of lactation, alone or in combination of single dose of Azithromycin as 20mg/kg to infants at 42 days of age on lenght velocity as primary, and weight velocity as secondary outcome.

Participants will receive nutrition counseling along with guidance related to exclusive breastfeeding and further assessment will be done to assess breast milk composition, Haemoglobin, Ferritin and Transferrin receptor, and inflammatory biomarkers, as secondary outcomes. Further, this study will also look at the comparison of length-for-age, weight-for-length, and weight-for-age Z scores as other secondary outcome at 6 months of age among three arms.

Primary outcomes

  1. Length velocity at 6 months of infant's age

    Time frame: 6 months of infant age, after birth and enrollment through monthly assessment

    Mean difference in length velocity of >0.12 cm /month to look at comparisons between multiple arms

Secondary outcomes

  1. Growth velocity at 6 months of infant's age

    Time frame: 6 months of infant age, after birth and enrollment through monthly assessment

    Mean difference in growth velocity of >0.4 gram/kg/day to look at comparisons between multiple arms

  2. Length-for-Age Z-score (LAZ) of infants at 6 months of age

    Time frame: 6 months of infant age, after birth and enrollment through monthly assessment

    Mean difference in LAZ >0.5 to look at comparisons between multiple arms

  3. Weight-for-Length Z-score (WLZ) of infants at 6 months of age

    Time frame: 6 months of infant age, after birth and enrollment through monthly assessment

    Mean difference in WLZ of >0.5 to look at comparisons between multiple arms

  4. Weight-for-Age Z-score of (WAZ) infants at 6 months of age

    Time frame: 6 months of infant age, after birth and enrollment through monthly assessment

    Mean difference in WAZ of >0.5 to look at comparisons between multiple arms

Other outcomes

  1. Breast milk composition

    Time frame: breast milk specimens will be collected at day 40-42 and 56 of infant age

    50 systematically selected lactating women in each arm will be approached for breast milk specimen to assess quality of breast milk composition (macro- and micro-nutrients), Human Milk Oligosaccharides (HMO), immunoglobulins and microbiome analysis. Same 50 women will be selected for outcome 7 and 8

  2. Stool specimens of lactating women and infants

    Time frame: At day 40-42 and 56 of infant age

    Same 50 systematically selected lactating women in each arm will also be approached for stool samples on the same day and stool from the same infant will also be collected. Stool will be collected for TaqMan Array Card (TAC) analysis of enteric pathogens, B. Infantis, Calprotectin, Lipocalin 2 and Myeloperoxidase (MPO) as a marker of gut inflammation and will be assessed using a metagenomic approach

  3. Blood specimens of lactating women

    Time frame: At day 40-42 and 56 of infant age

    Same 50 systematically selected lactating women in each arm will be approached for blood specimens to assess haemoglobin, serum Ferritin, Transferrin receptor and Acute phase proteins such as AGP and CRP

  4. Blood specimens of infants

    Time frame: At day 40-42 and 56 of infant age

    All infants will be approached for blood speciemens to assess haemoglobin, serum Ferritin, Transferrin receptor, plasma proteomics and Acute phase proteins such as AGP and CRP
