| Abstract |
Purpose
: Ugly ulcer and keloid formation of injection site has sometimes been a
problem in Korea from the cosmetic point of view in intradermal vaccination. Since 3 or
4 years ago, multipuncture BCG vaccination has been used in Korea, there are no data
and information about multipuncture BCG vaccination. We therefore performed this study
to evaluate of conversion rate, complication and to make criteria of horizontal induration
of Mantoux test instead of erythema to use criteria of positive Mantoux test in Japan.
Methods
: 124 neonates who were born Kon-Kuk university hospital without family
history of tuberculosis were given multipuncture BCG vaccination within 4 weeks after
birth between Mar. and Oct. 1995. We observed change of local lesion for 1-3 months
after BCG vaccination. All neonates tested a Mantoux test with 5TU of PPD 3 months
after multipuncture BCG vaccination.
Results
:
1) There was no significant difference in conversion rate of Mantoux test by feeding
pattern.
2) There was no change of number of puncture site 1-3 months after BCG vaccination.
3) There was no ulcer in change of local lesion. Pusture, scab and redness was
decreased 3 months after multipuncture BCG vaccination. Redness of all was replaced
pigmentation.
4) The means¡¾2SD of diameters of induration, erythema on Mantoux test were
10.4¡¾3.0mm in horizontal induration, 13.2¡¾4.2mm in horizontal erythema, 8.0¡¾3.0mm in
vertical induration, 10.9¡¾3.5mm in vertical erythema.
5) Criteria for positive tuberculin reaction were diameters of induration, erythema :
equal to or greater than 7mm of horizontal induration, equal to or greater than 5mm of
vertical induration, equal to or greater than 10mm of horizontal and vertical erythema.
6) The positve conversion tuberculin rate were 87.8% in horizontal induration, 87.5%
of vertical induration, 83.8% of horizontal erythema, 69.4% of vertical erythema.
7) Conversion rate of neonates immunized later 21 days after birth were significantly
greater than neonates immunized within 21 days after birth.
8) There was no correlate Mantoux test conversion rate and strong reaction of local
lesion.
9) There were no specific complication after multipuncture BCG vaccination.
10) There were no severe pain and irritability at multipuncture BCG vaccination.
Conclusion
: Multipuncture BCG is a good BCG vaccination that we can use with
efficacious effect and slight local lesions instead of intradermal BCG vaccination. |
