[Pulmonary hypertension caused by talcoma in a couple of drug addicts].

The authors report a case of severe pulmonary hypertension (PHT) in a couple of HIV seropositive heroin addicts. The parallel clinical course in these two patients with only mild immunodeficiency and the fact that they both had the same supplier were in favour of PHT secondary to talcoma. In the light of these cases, one wonders whether, as suggested by certain epidemiological studies currently underway, drug addiction should be considered to be a cause of PHT in its own right. According to the authors, this approach would underestimate the incidence of this disease in this particular population and would therefore bias the epidemiological data.
