- An enzyme-linked immunosorbent assay (ELISA) based on recombinant nucleocapsid protein (rN delta) (aa 1-117) of Hantaan, Seoul, Dobrava, Sin Nombre and Puumala hantaviruses was used to determine the prevalence of antibodies among randomized and stratified individuals from northern Sweden. In total, 137/1533 individuals (8.9%) had specific serum IgG antibodies to Puumala virus, the only hantavirus known to occur in the region. The prevalence of antibodies to Puumala virus (8.9%) was determined to be higher than previously reported (5.4%) in the same serum material, by use of immunofluorescence assay. As expected, sera reactive to Puumala virus rN delta did frequently cross-react with Sin Nombre virus protein. Unexpectedly, 21/1533 (1.4%) individuals recognized the Sin Nombre virus rN delta exclusively. Another 8 subjects showed reactivity in the ELISA to Hantaan, Seoul, or Dobrava virus-derived rN delta but not Puumala virus or Sin Nombre virus rN delta. The present demonstration in some individuals of antibodies specifically recognizing the Sin Nombre, Dobrava, Hantaan and Seoul virus protein justifies an awareness of the possibility that hantaviruses antigenically different from Puumala virus might occur in the region.

Tidskriftsartikel (refereegranskat)abstract
- The incidence, concomitant conditions and case fatality rate of Haemophilus influenzae (Hi) and pneumococcal meningitis and of invasive meningococcal infections were studied retrospectively in Sweden (population 8.4 million) for the years 1987-89, the period before vaccination against Hi type b started. A total of 1,019 cases with culture-verified infection were found. The incidence rates per 100,000 per year were 1.8 for Hi meningitis, 1.2 for pneumococcal meningitis and 1.0 for invasive meningococcal infections. The age-specific incidence was highest in the 3-23 months age group for the 3 bacterial species. Pneumococcal meningitis was common in individuals > or = 60 years and meningococcal infections in the age-group 10-24 years. A serious concomitant condition was known in 57% of all patients with pneumococcal meningitis while this was uncommon for the other organisms. The case fatality rate was 2% for Hi meningitis, 24% for pneumococcal meningitis and 10% for meningococcal infections. All 81 pneumococcal isolates which had been serotyped belonged to serotypes in the 23-valent pneumococcal vaccine. Of the meningococcal isolates, 65% belonged to serogroup B. In conclusion, the high incidence of Hib meningitis justifies general Hib vaccination. Development of a vaccine against N. meningitidis group B should have high priority. Furthermore, improved pneumococcal vaccines are needed for patients with predisposing conditions. The currently available pneumococcal polysaccharide vaccine seems to be underused.

Tidskriftsartikel (refereegranskat)abstract
- 16 patients with chronic hepatitis C virus (HCV) infection were treated with a combination of interferon-alpha and ribavirin for 24 weeks in an open study. One patient declined further treatment due to depression after week 16 and did not complete further follow-up. A moderate decline was observed in hemoglobin and an increase in bilirubin level both reversible after discontinuing the treatment. 24 weeks after treatment cessation 9/15 (60%) evaluable patients had complete clearance of HCV-RNA as measured with PCR. HCV genotype did not seem to be correlated with response, but patients with sustained response to treatment had a significantly reduced number of HCV RNA copies/ml serum at treatment start compared with the other patients. These findings support the promising results of this combination therapy noted in other pilot studies.

Tidskriftsartikel (refereegranskat)abstract
- To compare the clinical and microbiological efficacy of azithromycin in curing chlamydial infections in women with that of lymecycline, and with a view of the possibility of minimizing the problem of compliance by means of single-dose administration, 146 women with culture-positive Chlamydia trachomatis infections were randomly assigned to treatment with a 1 g bolus dose of azithromycin or a 10-day course of lymecycline 300 mg twice daily. Clinical and microbiological evaluations were performed and adverse effects monitored at check-ups after 15-35 and 40-65 days. Of the 146 patients enrolled in the study, 120 were evaluable. At the second check-up, C. trachomatis was found to have been eradicated in all patients in both treatment groups. Of the 51 patients who had clinical signs and symptoms of genital infection at enrolment, 96% (22/23) of those in the azithromycin group were considered cured (n = 18) or improved (n = 4), as compared with 100% (28/28) of those considered cured (n = 22) or improved (n = 6) in the lymecycline group. Adverse events related, or possibly related, to treatment were reported by 16 (21.6%) of the lymecycline group, but by only 6 (8.3%) of the azithromycin group. The 2 drugs were comparable with regard to microbiological and clinical efficacy in the treatment of genital chlamydial infection in women. The markedly lower rate of side-effects associated with azithromycin may be a feature conducive to patient compliance.

Intradermal hepatitis B vaccination in health care workers. Response rate and experiences from vaccination in clinical practise

-
Ingår i: Scandinavian Journal of Infectious Diseases. - : Informa UK Limited. - 0036-5548 .- 1651-1980. ; 31:2, s. 197-200

Tidskriftsartikel (refereegranskat)abstract
- Health care workers at risk for hepatitis B virus infection are recommended for vaccination. Low-dose intradermal (i.d.) administration of vaccine has been suggested as a less expensive alternative to intramuscular (i.m.) inoculation. To evaluate the i.d. vaccination route, health care workers were included in a prospective study. The subjects were vaccinated with 0.1 ml (= 2 microg) recombinant vaccine (Engerix B, SmithKline Beecham) i.d. at 0, 1 and 6 months. Two months after the third vaccination, measurement of the anti-HBs level was conducted. An anti-HBs level > or =10 IU/l was considered protective. Those with an anti-HBs level <10 IU/l were given a fourth dose with new serological control after another 2 months. The results are based on the 1406 subjects that it was possible to evaluate. The seroconversion rate to protective anti-HBs level after 3 doses was 68% and after 3 or 4 doses 89%. Factors associated with a lower response rate were increasing age (p<0.05) and smoking (p<0.001). Sex or body mass index had no influence on the results. Vaccination technique seems to be of utmost importance when the i.d. route is used. Well instructed and experienced nurses are required and quality control with follow-up of overall seroconversion rate within each centre is needed.

Diagnosis of pulmonary infections in immunocompromised patients by fiber-optic bronchoscopy with bronchoalveolar lavage and serology
- 1996
-
Ingår i: Scandinavian Journal of Infectious Diseases. - : Informa UK Limited. - 0036-5548 .- 1651-1980. ; 28:5, s. 479-485
-
Tidskriftsartikel (refereegranskat)abstract
- Fiber-optic bronchoscopy (FOB) and bronchoalveolar lavage (BAL) were performed on 67 occasions in 57 immunocompromised patients with symptoms consistent with pulmonary infection. Diagnosis was achieved more often in renal transplant patients than in patients with hematological malignancies (85% versus 28%). Culture (bacteria, virus, fungi), staining and microscopy (bacteria, fungi, Pneumocystis carinii (PC)) and antigen detection by indirect immunofluorescence (cytomegalovirus (CMV), respiratory viruses, PC, Legionella) were used for diagnosis. On 20 occasions transbronchial biopsies with histopathologic examination were performed. In addition, serology comprising the herpes group (HHV-6) and respiratory viruses was done. A microbial diagnosis was obtained on 45% of occasions. The most common pathogens found were CMV (31%) and PC (25%). On 22 (33%) occasions a rapid diagnosis of 1 or more microbial agents was obtained within 24 h by conventional staining or indirect immunofluorescence. The clinical relevance of findings of CMV, HHV-6, and Epstein-Barr virus in BAL by polymerase chain detection on 18, 6 and 3 occasions is discussed. On 4 occasions pathogenic bacteria were found. It was not possible to relate findings of coagulase-negative staphylococci, alpha-streptococci and Candida albicans to the pulmonary infection.

Hepatitis C virus transmission, 1988-1991, via blood components from donors subsequently found to be anti-HCV-positive
- 1996

Tidskriftsartikel (refereegranskat)abstract
- The recipients of blood components, from the first 12 anti-hepatitis C virus (HCV) positive donors identified by blood donor screening, 1985-1991, were traced retrospectively and tested to assess the HCV transmission rate, HCV genotypes and disease severity. Three enzyme-linked immunosorbent assay (ELISA) positive but RIBA-indeterminate and HCV RNA-negative donors did not transmit HCV to their 9 traced recipients. Nine RIBA- and HCV RNA-positive donors had donated blood to 27 now living recipients of whom 16/27 (59%) were viraemic 1-5 years later. Nine recipients had resolved infection, as determined by PCR HCV RNA. Five of these were RIBA-2 positive but HCV RNA-negative and 4 recipients were RIBA-2-indeterminate and HCV RNA-negative. Two recipients negative in all tests had probably received blood before the donor became infected with HCV. The HCV genotype in each case was identical between the donor and the recipient. Of the viraemic recipients, 50% (8/16) were unsuitable for further investigation or therapy due to their high age and/or underlying severe disease. At most, only 30% (8/27) of the recipients were suitable for further investigation and/or treatment. Two of these were already diagnosed as being infected with HCV before being traced. It is concluded that the benefit of a general tracing of recipients of blood components from HCV-infected donors is doubtful since only a few of them are suitable candidates for treatment. Our results seem to indicate that it is more appropriate to recommend anti-HCV testing to those seeking medical care who have received transfusions or undergone major surgery before 1992, i.e. before anti-HCV-screening was initiated.

Tidskriftsartikel (refereegranskat)abstract
- The objective of the study was to evaluate the economic consequences of a general childhood vaccination programme against Haemophilus influenzae type b (Hib) in Sweden. A retrospective pre-vaccination annual cohort of 0-4-y-old children was compared with an annual cohort of the same age group after a complete implemented vaccination program against Hib. The cost analysis shows that vaccination against Hib is cost saving when indirect costs are included in the analysis. In the cost-benefit analysis it is shown that society will gain approximately 88 million Swedish Crowns (SEK) annually when Hib vaccination is totally implemented. In conclusion, general childhood Hib vaccination is a cost-effective public health intervention in Swedish society.

Tidskriftsartikel (refereegranskat)abstract
- The number of patients with meningitis and bacteremia due to Haemophilus influenzae was studied in Sweden over the period 1987-1994. Conjugated H. influenzae type b vaccines were introduced in Sweden in 1992, and all children born after December 31, 1992, were offered vaccination free of charge. A rapid decline of H. influenzae meningitis and bacteraemia was observed in the autumn of 1993, when the expected peak incidence failed to appear. In the prevaccination period 1987-1991, the average annual incidence (cases/100,000) was 34.4 in children aged 0-4 years. In 1994, the annual incidence fell to 3.5. No significant decline was observed in older children or adults. There was a 92% reduction in the number of meningitis cases and an 83% reduction in cases of bacteraemia. A similar decline was noted in 2 regions which followed different strategies for the introduction of the vaccination programme.

Prevalence of Borrelia burgdorferi sensu lato infection in Ixodes ricinus in Sweden
- 1995
-
Ingår i: Scandinavian Journal of Infectious Diseases. - : Informa UK Limited. - 0036-5548 .- 1651-1980. ; 27:6, s. 597-601
-
Tidskriftsartikel (refereegranskat)abstract
- Between 1988-1991, a total of 3,141 Ixodes ricinus ticks, 2,740 adults and 401 nymphs, was collected from different localities in 23 of the 25 provinces of Sweden. The ticks were identified, dissected and examined for the presence of Borrelia spirochetes. Indirect immunofluorescence was performed, using an antiserum obtained from rabbits, immunized with sonicated, whole Borrelia burgdorferi spirochetes isolated from Swedish Ixodes ricinus ticks. Borrelia-positive I. ricinus were found in all 23 provinces. The prevalence of infection in adults ranged from 3% in Jämtland to 23% in Södermanland. In nymphs, the infection prevalence ranged from 0% in 9 provinces to 15% in Södermanland. A significantly greater proportion of the adult ticks were found to be positive for Borrelia in the southern and central parts of Sweden as compared to the northern part (Norrland). No significant difference in prevalence could be demonstrated between the western and eastern parts of Sweden. On average, 10% of the nymphs and 15% of the adult I. ricinus were positive for Borrelia. Of 41 non-I. ricinus ticks, none was positive for Borrelia. This study shows that Borrelia burgdorferi sensu lato is present throughout the distributional area of I. ricinus in Sweden. This should lead to increased awareness of signs and symptoms compatible with Lyme borreliosis in persons living in or visiting areas where I. ricinus is present.

Intrathecal immunoactivation in patients with HIV-1 infection is reduced by zidovudine but not by didanosine
- 1996
-
Ingår i: Scand J Infect Dis. - : Informa UK Limited. ; 28:4, s. 329-33
-
Tidskriftsartikel (refereegranskat)abstract
- The effect of zidovudine and didanosine on the cerebrospinal fluid (CSF) concentrations of neopterin was studied in 12 patients with human immunodeficiency virus type-1 (HIV-1) infection 3-12 months after initiation of antiretroviral therapy. Ten treatment periods on zidovudine and 7 on didanosine were analysed. The CSF concentrations of neopterin decreased by 63% (from 29.6 to 12.9 nmol/l, p < 0.01) during zidovudine but increased by 15% (from 22.6 to 25.9 nmol/l, not significant during didanosine treatment. The CSF monocytic cell count decreased during zidovudine but increased during didanosine treatment. The results suggest that zidovudine but not didanosine reduces intrathecal immunoactivation during HIV-1 infection.

-
Tidskriftsartikel (refereegranskat)abstract
- In a prospective study between January 1987 and December 1992, 103 patients with invasive Haemophilus influenzae (Hi) infection were identified in a well-defined population before large-scale Haemophilus influenzae type b (Hib) vaccination was introduced. The incidence (cases/100,000/year) of invasive Hi infection was 5.9 for the whole population, 55 for children 0-4 years old and as high as 2.8 for adults. Hib was the predominant cause of the infection (83 cases) in children but, in adults, 13/39 (30%) cases were caused by non-typable Hi and 6/39 (19%) by Hi serotype f. Three patients (3%) died and 6 (5.8%) suffered a permanent sequel from the infection. All patients with such a sequel had invasive Hib infection. No significant difference between patients 0-6 years old and matched controls regarding the frequency of subnormal serum levels of immunoglobulins was found.
