Drug addiction in hepatitis C patients leads to a lower quality of life.

The subjective health status of hepatitis C patients has been relatively poorly studied. By using the Short Form 36 (SF-36), health-related quality of life (HRQOL) was assessed in a group of 42 hepatitis C patients. In all nine scales examined, the scores were generally low, and present drug use and being single were associated with especially large reductions in HRQOL. Compared with the Norwegian norms, scores were lower across all nine scales and significantly lower in eight. The study showed that the hepatitis C patients had definite reductions in HRQOL, but the impairment could not be fully explained by their hepatitis. Different non-viral factors such as drug use and marital status significantly influenced the results. This underlines the importance of taking other factors into account when studying the health status of hepatitis C patients.

Hepatitis B virus infection in drug addicts: no acute fatalities, no chronicity and could have benefits.

In a group of 159 drug addicts with acute hepatitis B in the 1970s there were no fatalities. During an observation period of about 25 years, 51 of the 159 died of various causes, but no deaths could be attributed to the hepatitis B infection. From 1998 to 2001, a follow-up examination of 53 of the 108 patients still alive, none of the 53 had a chronic hepatitis B virus infection. Fifteen out of thirty-five patients who had completely stopped using narcotics claimed that hospitalisation for acute hepatitis B had been an important factor in their decision to quit drugs.

Death rates and causes of death in cohorts of serum hepatitis patients followed up for more than 20 years.

A cohort of 214 drug addicts with serum hepatitis and a cohort of 193 hepatitis patients without drug addiction were examined in respect of death rates, causes of death and a number of risk factors for reduced survival. The death rate was significantly higher among the drug addicts than among non-addicts. The annual mortality rate was 1.5% in the drug addict group and 0.7% in the non-addict group. The highest relative risk of death was 860 for female drug addicts in age group 15-24 compared to females of the same age in the general population. The most prevalent cause of death in the drug addict group was drug overdose (53%), whereas in the other group 66% died from various somatic diseases. Hepatitis or complications of viral hepatitis played no role as cause of death among the drug addicts, and infections as a whole were also responsible for very few deaths. For male drug addicts, imprisonment before admission and leaving hospital without the doctors' permission were risk factors for early death.

[Yellow staphylococci with borderline resistance to methicillin]. / Gule stafylokokker med nedsatt meticillinfølsomhet.

Over the last four years there has been an increase in the incidence of borderlineresistant Staphylococcus aureus isolated from bacteriological samples at the Ullevål University Hospital, Department of Medical Microbiology. Several severe infections caused by these bacteria have been noticed in the Department of Infectious Diseases at Ullevål University Hospital. From December 1994 to April 1997, 24 patients suffering from this type of S. aureus infection were examined with regard to clinical and microbiological outcome. 15 of the patients had hospital-acquired infections, and all except one had acquired the infection in Norway. 13 of the patients had at least one predisposing factor, 50% had received antibiotics (mainly cefalosporins) beforehand. Three of the 24 patients died from the infection. We discuss etiology, identification of groups at risk and management of the infection.

Adsorption of immunolgobulin A onto oral bacteria in vivo.

Oral bacteria become coated with immunoglobulin A in human saliva in vivo. This may indicate that the salivary immunoglobulin A possesses antibacterial activity. Some of the immunoglobulin-coated cocci grow in extremely long chains and exhibit synchronous cell division. The long chain phenomenon may result from growth in the presence of salivary antibody specific to antigenic determinants of the bacterial cell walls.

Immunoglobulin M: local synthesis and selective secretion in patients with immunoglobulin A deficiency.

Local synthesis seems to be decisive for the selective secretion of 19S immunoglobulin M into parotid secretions. The "transport piece" is apparently not involved in the secretion of immunoglobulin M, for there is no association between the two components. The possible significance of the normal association of transport piece with secreted immunoglobulin A remains to be clarified.
