G. Angarano et al., DRUG-RESISTANCE OF MYCOBACTERIUM-TUBERCULOSIS STRAINS ISOLATED FROM HIV-INFECTED ITALIAN PATIENTS - PRELIMINARY-REPORT FROM A MULTICENTRIC STUDY, The New microbiologica, 18(1), 1995, pp. 69-72
A multicentric prospective study started in March '93 to describe both
initial and acquired resistance of Mycobacterium Tuberculosis in Ital
ian HIV+ patients (Pyrazinamide (pts.) to first line drugs: Rifampin (
R), Isoniazid (I), Pyrazinamide (P), Ethambutol (E), Streptomycin (S).
All tuberculosis (TB) cases diagnosed in HIV+ patients (pts.) were in
cluded, along with clinical-anamnestical data. Drug-susceptibility tes
ts were performed centrally. Preliminary results indicate an overall l
ow frequency of TB resistance to first line drugs: R=2%, P=4%, S=9%, I
/E=none. However, a relevant nosocomial outbreak of multiple drug resi
stant (DR) TB was detected. This finding, along with some previous Ita
lian reports of DR-TB clusters, may herald a further spread of DR-TB.
Surveillance, therefore, is mandatory in Italy from now on.
