Herpesvirus in the oral cavity of children with leukaemia and its impact on the oral bacterial community profile

"Results
All the children with leukaemia were positive for at least one type of
herpesvirus, compared with healthy participants (33.3%;
p<0.000). Human cytomegalovirus
(HCMV; 46.7%), human herpesvirus-7 (HHV-7; 20%) and HHV-8 (77.3%) were
in higher prevalence
in the LG (p≤0.01). Children with
leukaemia had positive associations with the presence of HCMV, HHV-7 and
HHV-8 in the oral
cavity when under chemotherapy
(p<0.05). There was a qualitative (means of DGGE bands) and
quantitative (means of 16S rRNA
gene abundance) difference in
relation to the bacterial community between the two groups (p<0.05).
Conclusions
Based on the results, the prevalence of herpesviruses and the
qualitative bacterial profiles was higher in children with
leukaemia and HCMV, HHV-7 and HHV-8
were related to the use of chemotherapy. Moreover, HHV-6 was correlated
with an increased
bacterial community profile in
patients with leukaemia (p<0.05). More attention should be paid to
the oral health of these
individuals, mainly those under
chemotherapy, in order to prevent infections by opportunistic pathogens"
