Selective neonatal BCG vaccination: Specialist BCG clinics arean alternative
Dear Sir,
We read with interest the article by Bakshi and
Sharief [1]. Selective neonatal BCG vaccination is
currently recommended in the United Kingdom for
infants “at risk” of tuberculosis (TB). Most health
trusts have local guidelines based on an accepted
national policy of selective immunization as recom-
mended by the Department of Health [2] and the
British Thoracic Society [3]. Audits are mostly local,
limited to a health authority area, as there are no
studies done on a national basis.
The authors of the cited paper [1] have shown an
85% vaccination rate in Basildon, Essex, which is quite
encouraging. We would like to discuss a few issues that
have surfaced in recent times in our experience
regarding this issue. Defining “risk” of TB based only
on ethnicity of either parent excludes white British
children with family and/or contact history of TB,
asylum seekers of any ethnic origin and children of
travelling families among others who are perceived to
be at risk of TB as well. Surveillance of childhood TB
from September 1996 to December 1999 conducted
through the Welsh Paediatric Surveillance System
(WPSS) reported 38 cases of TB and 59 children on
chemoprophylaxis. The majority of cases were noted to
be in the white population, and most had not received
BCG [4]. This was consistent with a previous study
conducted in Wales [5]. Therefore, what constitutes
“risk” will have a significant bearing on the inter-
pretation of these results. Another issue is regarding
the exclusion of infants born to parents who had
not visited their home country for more than 5 y.
Reactivation of TB in their parents as well as exposure
to TB from visiting relatives will remain a possibility
in such cases. We agree that the major bulk of the
infants at risk do come from well-defined foreign
ethnic groups, but the above exclusions are clearly
important. Regarding the conclusion that neonates at
risk of TB rarely get immunized in the community, one
has to interpret this finding in light of the process
adopted to vaccinate these subjects. The authors are
testing their existing process of ensuring BCG vacci-
nation prior to hospital discharge, but not a process
designed for post-discharge vaccination in the
community.
In our experience, lack of junior doctor familiarity
with performing intradermal injections, lack of single
dose ampoules and vaccine availability over consider-
able periods of time in recent years (second half of
2002) make such a process of pre-discharge vacci-
nation difficult. Many health trusts now adopt a policy
of appointing these infants to specialist BCG clinics
manned by trained nursing teams experienced in
administering BCG vaccine. The advantage of such a
system is not only reliable vaccination technique, but
also review facilities with strong community links
which help in tracking defaulters and reappointing
them. This also gives TB prevention a holistic and
family-oriented dimension.
It has always been regarded ideal to catch the
“at risk” babies before their discharge, but the salient
issues are availability of vaccine and cost effectiveness
of using multidose vials on an ad hoc basis, thus regu-
larly wasting vaccine, as opposed to using full resources
by organizing “baby clinics” after discharge. More
importantly, the dubious efficacy of immunization
given by rather “unpractised” health professionals
(doctors or midwives) simply by virtue that they do not
get the opportunity to regularly practice the skill should
be borne in mind as well. Arguably, babies will benefit
more from having a BCG from someone who is
consistently administering the vaccine. The benefits
from having such a custom-built service will have a
broader applicability, considering that the issues
discussed are not peculiar to our local area in the UK.

Bilateral panuveitis and optic neuritis following BacillusCalmette-Guerin (BCG) vaccination
Sir,
Uveitis and associated arthritis have been reported
following intravesical and intradermal BCG vaccine
[1]. Yen and Liu reported the first case of bilateral optic
neuritis in a young girl following BCG vaccination [2].
We would like to describe a case of simultaneous
uveitis and optic neuritis following intradermal BCG
vaccination in a girl with immunoglobulin (IgA and
IgM) deficiency. To the best of our knowledge, we are
unaware of similar observations.
A 14-y-old girl was examined at an eye clinic for
bilateral sore and red eyes. Her presenting visual
acuity was 6/9 in the right and 2/60 in the left. On
examination of the left eye, positive findings were:
cells in the anterior chamber and a vitreous, relative
afferent pupilary defect and swollen optic disc. The
right eye also demonstrated few cells in aqueous and
vitreous with swollen optic disc. The retina looked
healthy in both eyes. Colour vision was reduced in
both eyes. Goldman visual field demonstrated gener-
alized constriction in either eye. She also complained
of accompanying sore wrists, which subsided with
oral non-steroidal anti-inflammatory tablets. Family
history revealed her brother as having a mild deficiency
of IgA and IgM. Five weeks prior to the sore eyes,
she had received BCG vaccination, as she was found
negative for tuberculin skin test. An investigation of
the brain and optic nerves with magnetic resonance
imaging scan was normal. Full blood count, serum
electrolytes, erythrocyte sedimentation rate (ESR),
C-reactive protein (CRP), serum calcium (Ca++),
serum angiotensin-converting enzyme, fluorescent
treponemal antibody test, viral serology, urinalysis,
chest X-ray, antinuclear antibodies and cerebro spinal
fluid analysis were normal. She was HLA-B27 and
rheumatoid factor negative. Her immunoglobulin assay
also showed low IgA (0.59 g/l) and IgM (0.29 g/l)
levels. She received 3 d of intravenous methyl predni-
sone (500 mg/d) followed by a tapering dose of oral
prednisolone (60 mg/d). She also received topical
prednisone (1%) QID and cyclopentolate (1%) BID to
both eyes. Both optic neuritis and uveitis resolved
completely with improvement in vision to 6/5 in both
eyes. Currently, she is on methotrexate (10 mg/wk)
with visual acuities of 6/5 in both eyes and almost full
recovery of visual fields.
A case of arthritis and iritis has been reported 3 wk
after BCG therapy for bladder cancer [3]. Our case
developed eye symptoms and arthritis 5 wk after the
BCG vaccination. Up to 25% of patients may have
ocular inflammation following BCG immunotherapy
in bladder cancer [1]. Arthritis following BCG vacci-
nation is mainly of the small joints (90%), consistent
with the sore wrists in our case [1]. The dose of BCG
vaccination is 0.05–0.1 ml; however, BCG immu-
notherapy for bladder cancer is between 50–120 mg
[4,5]. This dose difference may contribute to more
systemic side effects following BCG immunotherapy.
The amplification of the systemic side effects follow-
ing a BCG vaccine in our case has probably been
contributed by immunoglobulin deficiency. The
pathogenesis of complications following BCG immu-
notherapy is thought to be T-cell mediated, and the
role of HLA-B27 is debatable [1,6].
In the absence of other demonstrable aetiologies
and considering the close proximity to BCG vacci-
nation, we think the panuveitis and optic neuritis
is probably secondary to her vaccination. This
case suggests a strong causal relationship between
panuveitis and optic neuritis with BCG vaccination.
There is no definitive test to confirm this, and only
similar observations in the future can substantiate our
hypothesis.
