Trial Outcomes & Findings for Zinc and/or Probiotic Supplementation of Rotavirus and Oral Polio Virus Vaccines (NCT NCT01616693)

NCT ID: NCT01616693

Last Updated: 2018-12-26

Results Overview

Defined as an increase in serum anti-rotavirus (RV) VP6 IgA antibodies consistent with seroconversion (detection of serum anti-RV VP6 immunoglobulin A (IgA) antibodies at a concentration ≥20 U/ml in a previously seronegative individual) or a fourfold rise in anti-RV VP6 IgA antibodies between baseline and 14 weeks of age. Pre-vaccination blood samples were taken when the subject received the first dose of rotavirus vaccine (when the subject was 6 weeks of age); post-vaccination blood samples were taken 4 weeks after the second dose of rotavirus vaccine was administered (14 weeks of age).

Participant Flow

Potential participants for this study lived in the area surrounding the Christian Medical College (CMC) in the town of Vellore, Tamil Nadu, India. Parents were contacted through the existing Demographic Surveillance System shortly after the child's birth. Procedures were conducted in the Chinallapuram Field Clinic.

SECONDARY outcome

Timeframe: from first dose of OPV to 4 weeks after last dose of OPV

A serologic immune response to OPV is defined as a neutralizing antibody titer to polio virus subtype 3 greater than or equal to 1:8 at 14 weeks of age. This antigen will be used as a conservative estimate because it gives the lowest immune response of all three polio antigens. Pre-vaccination blood samples were taken when the subject received the first dose of OPV vaccine (when the subject was 6 weeks of age); post-vaccination blood samples were taken 4 weeks after the second dose of OPV was administered (14 weeks of age).

Population: Subjects who received the vaccination on schedule and had valid stool samples on the days of testing.

Shedding of rotavirus following vaccination through detection of rotavirus antigen by ELISA and confirmed as vaccine type by Real-time polymerase chain reaction (RT-PCR). Stool samples were collected on Day 0 (i.e., day of vaccination or -1), Day 4 (±1) and Day 7 (-1 to +2) post vaccination.

SECONDARY outcome

Timeframe: 0, 4 and/or 7 day post dose 2 of rotavirus vaccine

Population: Subjects who received the vaccination on schedule and had valid stool samples on the days of testing.

Shedding of rotavirus following vaccination through detection of rotavirus antigen by ELISA and confirmed as vaccine type by RT-PCR. Stool samples were collected on Day 0 (i.e., day of vaccination or -1), Day 4 (±1) and Day 7 (-1 to +2) post vaccination.

n=118 Participants
Received daily zinc and probiotic supplements, in addition to rotavirus vaccine and trivalent oral polio vaccines. Probiotic: A capsule that contains at least 1 x 10\^9 Lactobacillus rhamnosus GG organisms per capsule. The contents of this capsule were given once daily orally. Zinc: Zinc sulphate syrup is zinc sulphate heptahydrate (concentration 1mg/ml). 5 ml of this suspension was given once daily orally.

SECONDARY outcome

Timeframe: from first day of study to 4 weeks after last dose

Field workers documented information on SAEs through the duration of the study during home visits (twice weekly between study clinic visits) or SAEs were documented by study clinicians at the study clinic or hospital. All SAEs occurring at any time during the study were recorded on a SAE Form and were reviewed and evaluated by a study clinician and the local IRB. The relationship of the SAE to study vaccine was evaluated and recorded and reported to the local institutional review board (IRB). All SAEs were followed until satisfactory resolution.
