Drug Resistant Tuberculosis in Special Situations
Pp. 76-83 (8)
There are three special situations in drug resistant tuberculosis that merit a
more detail description: HIV co-infection, pregnancy and drug resistant TB in children.
HIV co-infection: The risk of reactivation of latent tuberculosis infection is 50-100
times higher for subject living with HIV and up to 170 times higher for those with
AIDS. Every patient diagnosed with TB must be tested for HIV infection and vice
versa. The WHO recommends that ARV treatment in patients recently diagnosed as
co-infected with HIV and tuberculosis should start within 8 weeks from the start on
Pregnancy: The best way to deal with MDR-TB during pregnancy is to prevent it. All
females of child-bearing age being treated for MDR-TB should be encouraged to adopt
an effective contraceptive method or even a combination of them. Most of the drugs
used to treat MDR-TB are classified as unsafe during pregnancy or their safety is
Pediatric tuberculosis: Unlike the adults, most MDR-TB pediatric cases are the result
of infection with an already resistant strain, frequently from contact with a household
adult. Children with signs and symptoms compatible with active tuberculosis and risk
factors for MDR-TB should be started on MDR-TB treatment even if the diagnosis has
not been confirmed bacteriologically.
