Material and Methods. Estimates of incidence and spectrum of EPTB
in Siberia are presented on the basis of the statistical reports for 1999 –
2009.
Results. During the last decade the incidence rate of TB in Siberia
increased up to 20%. Every year there are about 1000 new EPTB
patients. Within the last decade the spectrum of EPTB has changed
significantly. TB of the central nervous system almost doubled from
4.9% to 8.5%, mostly due to co-morbidity with HIV. Bone and joints
TB increased from 20.3% to 30.8%, and among this group TB
spondylitis with neurological disorders predominates. The proportion of
UGTB decreased from 42.9% to 33.9% with change in gender
distribution from male : female of 1:2 in 1999 to 1:1 in 2008. In
contrary, there was a decrease of peripheral lymph nodes TB from
16.7% to 11.0%, but fistulous disease still frequent. At the end of the
last century ocular TB in Siberia accounted for 7.4% and in 2008 (in
2009 listed in “others”) for 4.4% of the patients with EPTB.
Accordingly, in 1999 other form of TB accounted for 7.8% and in 2009
for 15.8%.
