RESUMO
During a 3-year period (August 1st, 1985 to July 31st, 1988) a systematic investigation of medico-legal autopsy cases with regard to the presence of antibodies for HIV-virus was carried out at the Department of Forensic Medicine in Stockholm, Sweden. Prior to autopsy, blood samples were taken from femoral or subclavian veins and were investigated by use of ELISA-screening and Western blotting test. During the first year of study, HIV infection was demonstrated in 11 out of 3464 deaths (0.32%), during the second year in 29 out of 3483 deaths (0.83%), and during the last year in 13 out of 3107 deaths (0.42%). It was shown that 48 out of the total of 53 HIV positive cases were previously registered, but information about the infection was available to the autopsist in only 27 cases. Drug addicts dominated 41 of 53 cases. There were only eight homo- and bisexual males, two non drug addict Central Africans and two persons who received blood transfusions. Eight of the 53 persons died of natural causes whereas 45 deaths were due to violence and drugs. The causes of death of the HIV positive drug addicts were compared to the causes of death of the HIV negative addicts. The HIV positive drug addicts tended to die suddenly in connection with the intravenous administration of heroin and at lower blood concentrations of morphine more often than the HIV-negative addicts. No increase in the suicide frequency was noted in drug addicts in Stockholm during the studied period.
