- Acanthamoeba species are widely distributed free-living amoebae showing an increased role as human pathogens causing encephalitis, keratitis, pneumonitis and dermatitis. A haematopoietic stem cell transplanted (HSCT) patient developed purulent meningitis while awaiting regrafting. The meningitis was thought to be an endogenous infection arising from the mucous membranes primarily involving the cervicofacial regions, probably due to haematogenous spread facilitated by surgery. We diagnosed a fatal case of granulomatous amoebic encephalitis caused by Acanthamoeba castellanii by direct microscopy of a cerebrospinal fluid sample (CSF), Acanthamoeba cultivation, Giemsa staining, polymerase chain reaction and sequencing.

In: Scandinavian Journal of Infectious Diseases. - : Informa UK Limited. - 0036-5548 .- 1651-1980. ; 47:4, s. 209-217

Journal article (peer-reviewed)abstract
- Background: Relapse of hepatitis C virus (HCV) infection after liver transplantation (LT) is universal. Tolerance for treatment with pegylated-interferon (peg-IFN) and ribavirin (RBV) is suboptimal and withdrawals due to adverse events frequent. We sought to improve tolerance for treatment to improve outcome. Methods: We used concentration-guided RBV dosing to achieve an intended 10 mu mol/L concentration with darbepoetin support in combination with peg-IFN alfa-2a, 180 mu g for genotype 1 and 135 mu g for genotype 2/3 to improve tolerance. Results: A total of 51/54 patients (94%) completed a full treatment course. In the per-protocol analysis 43% of patients (22/51) achieved sustained virological response (SVR), 82% with HCV genotype 2/3 and 22% with genotype 1, p = 0.0001. Patients with IL28B CC achieved SVR in 73% (8/11) and patients with non-CC in 33% (14/43), p = 0.016. Patients with mild fi brosis (fi brosis stage 1-2) achieved SVR in 56% (15/27), and patients with advanced fi brosis (fi brosis stage 3 -4) in only 26% (7/27), p = 0.0267. Conclusions: Concentration-guided RBV dosing with darbepoetin support substantially improves tolerance and offers high adherence to a full peg-IFN and RBV treatment course in patients with post-transplant HCV relapse. With this approach genotype 2 and 3 infections can be treated cost-effectively post-transplant. Genotype 1, IL28B non-CC genotype, and advanced fi brosis predicted a low SVR rate.

Bacterial aetiology in ventilator-associated pneumonia at a Swedish university hospital
- 2010
-
In: Scandinavian Journal of Infectious Diseases. - : Informa UK Limited. - 1651-1980 .- 0036-5548. ; 42:6-7, s. 469-474

Journal article (peer-reviewed)abstract
- Ventilator-associated pneumonia (VAP) is a common complication of respiratory support and is associated with increased mortality, morbidity and costs, and a prolonged stay in the intensive care unit. Scandinavian data on the aetiology in VAP are lacking. We hereby present a retrospective study on the aetiology of VAP diagnosed by protective specimen brush culture at Malmo University Hospital in relation to early-and late-onset VAP, antibiotic treatment and the incidence of drug-resistant bacteria. Patients registered with a diagnosis of VAP between January 2004 and September 2007 were included in the study. Sixty-five of 109 patients diagnosed with VAP met the inclusion criteria, and 103 bacterial isolates were cultured from these patients. The most common findings among the 65 VAP episodes were Enterobacteriaceae (28), Pseudomonas aeruginosa (13), Haemophilus influenzae (12) and Staphylococcus aureus (8). Patients with no antibiotic treatment at the onset of VAP had significantly more H. influenzae (p = 0.035) and Gram-positive pathogenic bacteria (p = 0.019). There was no difference in incidence of P. aeruginosa between early-and late-onset VAP. Resistant bacteria were found in 18% of the patients.

Brain abscess caused by methicillin-resistant Staphylococcus aureus
- 2000

Journal article (peer-reviewed)abstract
- A Swedish tourist was admitted to a Cuban hospital due to epileptic seizures caused by brain tumors. Upon return to Sweden and admission to our hospital, methicillin-resistant Staphylococcus aureus (MRSA) was isolated. He was later considered to be free of MRSA but then developed a brain abscess from which MRSA was isolated.

Health problems and self-medication among Swedish travellers.
- 1994
-
In: Scandinavian Journal of Infectious Diseases. - 0036-5548 .- 1651-1980. ; 26:6, s. 711-7
-
Journal article (peer-reviewed)abstract
- 500 consecutive travellers seeking pre-travel health advice were issued a questionnaire before leaving Sweden to continuously record health problems and use of medication during travel. Of 442 subjects who turned in assessable questionnaires (232 male and 210 female, mean age 37 years), 81% travelled to areas at high risk for the acquisition of diarrhea. The mean duration of travel was 4 weeks. During travel 218 (49% at 95% CI 44.3 to 53.7%) of the travellers experienced some illness and 61 (14%) had symptoms of more than one illness. The mean duration of illness was 4.5 days, and 65 subjects (30% of ill travellers) were confined to bed for a mean duration of 2 days. The incidence of illness was significantly (p < 0.01) higher among travellers to high risk than to low risk areas (55% vs 26%), among young travellers than among elderly (65% vs 33%), and among those going on adventure tours compared with recreational tourists (74% vs 41%). Diarrhea was reported by 36% (95% CI 31.6 to 40.5%), and respiratory tract infection by 21% (95% CI 17.2 to 24.8%). Self-medication with one or several drugs was initiated by 163 (75%) travellers experiencing illness during travel. Thus, every second Swedish traveller to tropical and subtropical areas experienced some kind of travel-related, often incapacitating, health problem.

Prevalence of serum antibodies to hantaviruses in northern Sweden as measured by recombinant nucleocapsid proteins.
- 1997
-
In: Scandinavian Journal of Infectious Diseases. - : Informa UK Limited. - 0036-5548 .- 1651-1980. ; 29:4, s. 349-54
-
Journal article (peer-reviewed)abstract
- 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.
