- 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.

Tidskriftsartikel (refereegranskat)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.

- 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.

- 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.

Tidskriftsartikel (refereegranskat)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.

Risk of HIV transmission from patients on antiretroviral therapy: A position statement from the Public Health Agency of Sweden and the Swedish Reference Group for Antiviral Therapy
- 2014

Tidskriftsartikel (refereegranskat)abstract
- The modern medical treatment of HIV with antiretroviral therapy (ART) has drastically reduced the morbidity and mortality in patients infected with this virus. ART has also been shown to reduce the transmission risk from individual patients as well as the spread of the infection at the population level. This position statement from the Public Health Agency of Sweden and the Swedish Reference Group for Antiviral Therapy is based on a workshop organized in the fall of 2012. It summarizes the latest research and knowledge on the risk of HIV transmission from patients on ART, with a focus on the risk of sexual transmission. The risk of transmission via shared injection equipment among intravenous drug users is also examined, as is the risk of mother-to-child transmission. Based on current knowledge, the risk of transmission through vaginal or anal intercourse involving the use of a condom has been judged to be minimal, provided that the person infected with HIV fulfils the criteria for effective ART. This probably also applies to unprotected intercourse, provided that no other sexually transmitted infections are present, although it is not currently possible to fully support this conclusion with direct scientific evidence. ART is judged to markedly reduce the risk of blood-borne transmission between people who share injection equipment. Finally, the risk of transmission from mother to child is very low, provided that ART is started well in advance of delivery.

Infective endocarditis: a diagnostic and therapeutic challenge for the new millennium.

Tidskriftsartikel (refereegranskat)abstract
- This review on infective endocarditis (IE) is based on clinical studies carried out in Göteborg since 1984, data obtained from a Swedish national registry of IE since 1995 and existing literature. IE is still a great challenge in medicine, although improved bacteriological and echocardiographical techniques have facilitated diagnosis. In Sweden the incidence of IE is about 6 per 100,000 inhabitants a year. During recent decades IE has changed character. Patients are older, fever is often the only major symptom and a new murmur is less frequent. Streptococci, including viridans species and staphylococci, are still the most common bacteria found. Antibiotic treatment for 4-6 weeks may reduce mortality of IE to 30-50%. For further reduction, heart surgery is necessary in 20-25% of patients in order to remove infected tissues and restore valve function. Rapid diagnosis, careful antibiotic treatment and optimal surgery may reduce mortality associated with treatment to 10%. Antibiotic treatment is still mainly empiric. Penicillin and aminoglycoside for 2 weeks only seem to be effective in uncomplicated IE caused by alpha-streptococci. Otherwise, 4 weeks of treatment is needed, but aminoglycoside treatment may be reduced to 1 week in general and 2 weeks for enterococcal infections.

Tidskriftsartikel (refereegranskat)abstract
- In 2009 we described an outbreak caused by extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli in southern Sweden that occurred during 2005–2006. An important finding from the investigation was the long carriage times of the ESBL-producing E. coli in several of the patients, which in some cases exceeded 30 months. Here we report findings from the continued follow-up of bacterial carriage. In September 2010, 5 of the 42 patients still carried the bacteria after a median of 58 months (range 41–59 months), 18 had had repeatedly negative cultures after shedding bacteria for a median of 7.5 months (range 0–39 months), 16 had died while still shedding the bacteria for a median of 9 months (range 0–38 months), and 3 had been lost to follow-up.

Tidskriftsartikel (refereegranskat)abstract
- Recently, molecular methods capable of detecting almost all microbial agents that may cause acute respiratory infection have been introduced. The FilmArray Respiratory Panel assay, which integrates nucleic acid extraction, nested amplification and detection in a reaction pouch preloaded with all reagents required for detection of 17 viruses and 3 bacteria, was compared with an in-house real-time PCR that detects these agents in 8 parallel amplifications. When 128 clinical samples representing 18 of these agents were analysed by both assays the agreement was excellent, with kappa values ranging between 0.54 and 1.0. Discordances were mainly observed for adenovirus, but not when version 1.7 of FilmArray was used. The results show that these assays detect a wide range of pathogens with similar performance. FilmArray provides results after approximately 1 h, including approximate to 5 min hands-on time, and does not require advanced equipment or expertise in molecular diagnostics, making it a useful point-of-care-test for acute respiratory infections.

Tidskriftsartikel (refereegranskat)abstract
- Abstract Background: The aims of this study were to investigate the prevalence of methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE) and extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae in residents living in Swedish nursing homes, and if carriage of resistant bacteria was related to antibiotic treatment, other risk factors, and/or staff's adherence to guidelines for infection control. Methods: Five hundred and sixty residents from 9 nursing homes on a total of 67 wards participated in the study and had microbiological cultures taken. Faecal samples were obtained from 495 residents (88.3%). ESBL-positive residents were followed for 2 y with repeated sampling. Two hundred and ninety-six staff members were interviewed and observed regarding familiarity with and adherence to infection control guidelines. Results: No resident was positive for MRSA or VRE. Fifteen of the residents were found to be ESBL-positive. Residents living on wards where ESBL-positive residents were identified had been treated more frequently with antibiotics (42%), compared to those on wards where no residents with ESBL were found (28%; p = 0.02). ESBL-positive Escherichia coli isolates from residents living in adjacent rooms were found to be closely genetically related when analysed by pulsed-field gel electrophoresis, indicating transmission between residents. Staff adherence to infection control guidelines sometimes revealed shortcomings, but no significant differences regarding compliance to the guidelines could be found. Conclusion: Carriage of resistant bacteria was uncommon and only ESBL-producing Enterobacteriaceae were identified in Swedish nursing homes. Usage of antibiotics was higher on wards where ESBL-positive residents were detected and there was an indication of transmission of ESBL between residents.

- Background: The objective of this study was to compare the efficacy of ritonavir boosted atazanavir versus ritonavir boosted lopinavir or efavirenz, all in combination with 2 nucleoside analogue reverse transcriptase inhibitors (NRTIs), over 144 weeks in antiretroviral-naïve HIV-1-infected individuals. Methods: A prospective open-label randomized controlled trial was conducted at 29 sites in Sweden and Norway between April 2004 and December 2009. Patients were randomized to receive either efavirenz 600 mg once daily (EFV), or atazanavir 300 mg and ritonavir 100 mg once daily (AZV/r), or lopinavir 400 mg and ritonavir 100 mg twice daily (LPV/r). The primary endpoints were the proportion of patients with HIV-1 RNA 100,000 copies/ml at baseline had similar response rates in all arms. Conclusion: EFV was superior to LPV/r at week 48, but there were no significant differences between the 3 arms in the long-term (144 weeks) follow-up.

- The aim of this study is to present diagnostic patterns, diagnostics used and antibiotic treatment in relation to guidelines in 3 repeated diagnosis-prescription studies conducted simultaneously in general practice in 5 Swedish counties, during 1 week in November 2000, 2002 and 2005. General practitioners (GPs) at the participating health centres were asked to complete a form for all patients with symptoms of an infectious disease. During the studied periods a total of 15,371 consultations was registered. Consultations with GPs diagnosed as respiratory tract infection (RTI), especially consultations for sore throat, decreased considerably between y 2000 and 2005. The percentage of patients allocated an RTI diagnosis and prescribed an antibiotic declined significantly from 54% to 49% and the decline was most pronounced among children. Penicillin V remained the dominant antibiotic prescribed throughout the study periods. For lower urinary tract infections there was a significant change in choice of prescribed antibiotics with an increase for pivmecillinam and nitrofurantoin and a decrease for trimethoprim, in accordance with recommendations. The results indicate a quite close adherence to current guidelines, with changes in the pattern of consultations as well as in the management of infectious diseases in general practice in Sweden.

Tidskriftsartikel (refereegranskat)abstract
- A diagnosis-antibiotic prescribing study was performed in 5 counties in Sweden during 1 week in November in the y 2000 and 2002, respectively. As part of the study, the characteristics and clinical management of patients who received diagnoses of urinary tract infections (UTIs) (n = 1564) in primary care, were analysed. 85% of the visits were by women, and 74% of all consultations were diagnosed as lower UTIs. One or more diagnostic tests were performed in 98% of the women with suspected lower or recurrent UTIs and 95% were prescribed an antibiotic. The most commonly prescribed antibiotics for lower UTIs were trimethoprim followed by pivmecillinam and a quinolone. The study indicated a change in antibiotic prescribing with improved adherence to the national recommendations. There was an increase of prescribed nitrofurantoin and a decrease of prescribed quinolones to women with lower UTIs between the studied y. Furthermore, 3-d treatment with trimethoprim increased although the prescribed duration was mostly 7 d. In contrast to the guidelines, few urine cultures were performed. The study highlights the necessity of updating the guidelines for the management of lower UTIs in general practice.

Tidskriftsartikel (refereegranskat)abstract
- A diagnosis-prescribing study was performed in 5 Swedish counties during 1 week in November in 2000 and repeated in 2002. The aim of the present study was to analyse data for children 0-15y of age who consulted a general practitioner with symptoms of an infection. During the 2 weeks studied, 4049 children were consulted. Respiratory tract infections (RTI) were the predominant diagnoses, above all among the youngest children, while the proportion of urinary tract infections and skin infections increased with increasing age. Between the y 2000 and 2002, the proportion of children allocated the diagnosis streptococcal tonsillitis and pneumonia decreased (p<0.01 and p<0.001, respectively) while the proportion of common cold increased (p<0.001). Antibiotic prescribing decreased from 55% to 48% (p<0.001) for respiratory infections between the years studied. The only significant changes in type of antibiotics prescribed were the increase of isoxazolylpenicillins (p<0.001) used for skin infection and the decrease of macrolides (p=0.001). A diagnostic test was used in more than half of the consultations. Of children allocated a RTI diagnosis, 36% were prescribed antibiotics when a C-reactive protein test was performed compared to 58% in those not tested. Further studies are needed in general practice to determine the optimal use of near-patient tests in children with RTI.

Tidskriftsartikel (refereegranskat)abstract
- A diagnosis-antibiotic prescribing study was performed in 5 counties in Sweden during 1 week in November in 2000 and 2002 respectively. As a part of the study, the use and results of C-reactive protein (CRP) tests in relation to duration of symptoms and antibiotic prescribing in 6778 patients assigned a diagnosis of respiratory tract infections were analysed. In almost half (42%) of the patients, a CRP test was performed. The majority of CRP tests (69%) were performed in patients assigned diagnosis upper respiratory tract infection, where the test is not recommended. Overall, there was a minor decrease in antibiotic prescribing when CRP was used (41%), in comparison to 44% of the patients where no CRP was performed (p<0.01). Patients assigned diagnoses implying a bacterial aetiology were prescribed antibiotics irrespective of result of CRP or length of symptoms before consultation. For patients assigned viral diagnoses, antibiotic prescribing increased with increasing duration of symptoms and increasing value of CRP. The use of CRP decreased antibiotic prescribing in patients assigned to viral diagnoses and with longstanding symptoms (p<0.001). However, 59% of the patients assigned viral diagnoses with CRP≥25 received antibiotics, which seems to indicate a misinterpretation of CRP and a non-optimal use of antibiotics.

Tidskriftsartikel (refereegranskat)abstract
- A diagnosis/antibiotic prescribing study was performed in 5 counties in Sweden for 1 week in November 2000. As part of this study, the characteristics and clinical management of patients with upper respiratory tract infections (n = 2899) in primary care were analyzed. Almost half of the patients were aged < 15 y and one-fifth of the patients consulted out of hours. Of all patients seeking primary care for upper respiratory tract infections, 56.0% were prescribed an antibiotic. Almost all patients who were given the diagnoses streptococcal tonsillitis, acute otitis media or acute sinusitis were prescribed antibiotics, compared to 10% of patients with common cold or acute pharyngitis. The most frequently prescribed antibiotic was penicillin V (79.2%) and this was even more pronounced out of hours, when the diagnoses otitis media and streptococcal tonsillitis were more frequently used. In patients with common cold and acute pharyngitis, the percentage who received antibiotics increased with increasing length of symptoms and increasing CRP levels. In patients with acute pharyngitis or streptococcal tonsillitis, antibiotics were prescribed less frequently provided streptococcal tests were performed. The management of patients with upper respiratory tract infections in general practice seems to be in good agreement with current Swedish guidelines. However, the study indicates some areas for improvement. The diagnosis of acute sinusitis seems to have been overestimated and used only to justify antibiotic treatment.

- Background: To our knowledge no clinical criteria for the identification of community onset viral gastroenteritis in individual patients have been evaluated systematically with modern PCR-based diagnostic assays as gold standard. Objective: The aim of this study was to identify factors independently associated with the detection of virus by PCR in rectal swab samples from patients with acute community onset gastroenteritis. Methods: A prospective observational study was conducted from December 2010 through March 2011 at the emergency department (ED) of a large teaching hospital. All patients who reported vomiting and/or diarrhoea up to 48 h prior to their visit to the ED were asked to participate. A rectal swab sample was obtained from each patient. Symptoms, date of onset, and epidemiological data were recorded. Samples were analysed with a multiple real-time PCR targeting 6 viral agents (astrovirus, adenovirus, rotavirus, sapovirus, and norovirus GI and GII). Results: Two hundred and five patients fulfilled the inclusion criteria, of whom 66 agreed to participate; their median (IQR) age was 65 (38-84) y and 43 (65%) were females. Thirty-one (47%) were positive by PCR for at least 1 of the agents examined (26 norovirus, 2 sapovirus, 2 rotavirus, and 1 adenovirus). Diarrhoea and a short duration of symptoms (≤ 2 days) were independently associated with a positive rectal swab sample, with odds ratios of 7.5 (95% confidence interval (CI) 2.0-28) and 10.4 (95% CI 1.9-56), respectively (p < 0.01 for both). A multivariate model including these 2 variables had a sensitivity of 81% (25/31) and a specificity of 69% (24/35). Conclusions: Diarrhoea and a short duration of symptoms were the only anamnestic criteria independently associated with acute community onset viral gastroenteritis confirmed by PCR.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The Travel Medicine Clinic in Umeå is one of Sweden's largest public providers of vaccination and counselling prior to international travel. During the study period it was the only travel medicine clinic in Umeå. This study describes the demography of the visitors to the clinic and travel destinations and durations, as well as vaccinations administered. METHODS: This was a retrospective study for the period January 2005 to April 2008 based on pre-travel consultation questionnaires and on vaccine expenditure data. A 10% sample of 16,735 first visits prior to international travel was consecutively selected according to the chronology of the visits. RESULTS: Data on 1698 travellers were included in the study. Thailand was the most common destination among visitors, accounting for one third of all destinations. Medical problems affecting pre-travel health planning were rare. Four out of 5 visitors (79%) received only 1 vaccination, mainly for hepatitis A. Travellers to Thailand more often sought travel health advice compared to travellers to Turkey, despite the fact that the 2 destinations were almost equally distributed among travellers from Umeå. We found differences between men and women in money spent on vaccines and in particular in vaccination against Japanese encephalitis. CONCLUSIONS: To assess the optimal vaccination level at a travel medicine clinic is difficult. Decisions are affected by general recommendations and the risk perception of the travel medicine practitioner, as well as the risk perception of the traveller. The sex difference found in this study might be due to gender differences in risk perception and should be further investigated.

Tidskriftsartikel (refereegranskat)abstract
- Background: Travel health advice is an important and difficult part of a pre-travel consultation. The aim of this study was to determine whether the travel health advice given is followed by the traveller and whether it affects disease and injury experienced during travel. Methods: A prospective survey study was carried out from October 2009 to April 2012 at the Travel Medicine Clinic of the Department of Infectious Diseases, Umea University Hospital, Umea, Sweden. The Travel Medicine Clinic in Umea is the largest travel clinic in northern Sweden. Results: We included 1277 individuals in the study; 1059 (83%) responded to the post-travel questionnaire. Most visitors (88%) remembered having received travel health advice; among these, 95% found some of the health advice useful. Two-thirds (67%) claimed to have followed the advice, but fell ill during travel to the same extent as those who did not. Younger travellers (< 31 y) found our travel health advice less beneficial, were less compliant with the advice, took more risks during travel, and fell ill during travel to a greater extent than older travellers. Conclusions: Helping travellers stay healthy during travel is the main goal of travel medicine. Younger travellers are a risk group for illness during travel and there is a need to find new methods to help them avoid illness. Travellers find travel health advice useful, but it does not protect them from travel-related illness. Factors not easily influenced by the traveller play a role, but a comprehensive analysis of the benefits of travel health advice is needed.

Tidskriftsartikel (refereegranskat)abstract
- We have investigated pre-travel advice, behaviour, chemoprophylaxis and diagnostic delay in travellers returning to Sweden with falciparum malaria. Questionnaires were distributed to patients having been notified with falciparum malaria from 1994 to 2001. Of 408 notified patients, 237 (58%) returned the questionnaires; 62% were males and 43% above the age of 45 y. Africa was the travel destination in 90% of the cases, and 27% had travelled to Kenya. 69% had spent more than 1 night in the countryside, and 6% had stayed in modern urban areas only. 40% took an adequate dose of chemoprophylaxis, although this proportion decreased from 55% to 12% during the study period. Nine per cent used both bed nets and mosquito repellents regularly. The median time from onset of symptoms to contact with health care professionals was 2 d, and from that contact to start of malaria treatment the median time was less than 24 h.

Tidskriftsartikel (refereegranskat)abstract
- Beta-haemolytic group A streptococci (GAS) is a common cause of sore throat, usually spread person-to-person. Outbreaks related to infected food have more seldom been reported. The bacteria may originate from the throat or from wounds on the hands of persons handling the food. An outbreak in Sätila, Sweden, in April/May 2003 involving 153 individuals who fell ill after eating contaminated 'sandwich-layer cakes' was investigated in a descriptive, retrospective cohort study. Questionnaires were distributed, one immediately after the outbreak and one 3 months later. The average attack rate was 72%. 143 individuals sought medical care and 137 were treated with antibiotics. 76 individuals were ill for more than 4 days. GAS isolates of identical T-type were obtained from the throats of the patients, wounds on the caterer's fingers and also from the cakes. PFGE banding patterns of 14 representative isolates were identical, as well as the emm-sequence type, emm 89, of 3 chosen isolates. The study shows that GAS from a small wound on a finger can cause illness in a large number of individuals. To prevent further outbreaks, it is important to increase public awareness of this type of transmission.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The use of nasopharyngeal secretions to enhance diagnostic yields of pneumococcal aetiology in community-acquired pneumonia (CAP) is of interest. We evaluated the Binax NOW Streptococcus pneumoniae immunochromatographic test (ICT) on nasopharyngeal aspirates (NPA) in order to support pneumococcal aetiology in CAP.METHODS: The NPA ICT was applied on 180 adult CAP patients and 64 healthy controls. The rate of pneumococcal detection in the nasopharynx was compared to rates for lytA polymerase chain reaction (PCR) and culture on NPA.RESULTS: According to blood and sputum culture and urine ICT, the test sensitivity in 59 patients with a pneumococcal aetiology was 81%. The specificity was suboptimal, with 72% negative tests among CAP patients without a pneumococcal aetiology. However, the test was positive in only 11% of patients with atypical pneumonia and in 4.7% of healthy controls. The positivity rate was higher for NPA ICT compared to culture on NPA in all CAP patients, and to both PCR and culture on NPA in non-pneumococcal non-atypical CAP patients. In 113 (63%) patients with β-lactam monotherapy, cure without treatment alteration was noted more often in cases with positive compared to negative NPA ICT at admission (91% vs 69%; p < 0.01).CONCLUSIONS: The high sensitivity and the low positivity rates in patients with atypical pneumonia and healthy controls, in combination with the correlation between positive test results and clinical cure with β-lactam therapy, may support a pneumococcal aetiology in CAP in populations with low pneumococcal carriage rates.

Interaction of staphylococcus epidermidis from infected hip prostheses with neutrophil granulocytes
- 2001
-
Ingår i: Scandinavian Journal of Infectious Diseases. - : Informa UK Limited. - 0036-5548 .- 1651-1980. ; 33:6, s. 408-412

Tidskriftsartikel (refereegranskat)abstract
- This study focuses on the interaction of Staphylococcus epidermis isolated from granulation tissue covering infected hip prostheses and neutrophil granulocytes. Bacterial strains isolated from normal flora were used as controls. The bacteria were well characterized with routine methods and further characterized with random amplified polymorphic DNA analyses and slime tests. Phagocytosis and chemiluminescence (CL) assays were used in the neutrophil interaction studies. The prostheses strains were ingested to a lesser extent than strains from normal flora (p ≤ 0.001). There was no significant difference between the prostheses strains and the normal flora strains in terms of total CL response. However, the extracellular CL response from the neutrophils was lower in comparison with the normal flora when interacting with the prostheses strains. The results of this study support the notion that S. epidermidis strains isolated from infected hip prostheses have an enhanced capacity to resist phagocytosis and that most of these strains elicit a reduced inflammatory response, measured as the production of extracellular oxidative metabolites from the neutrophils, compared to normal flora.

Tidskriftsartikel (refereegranskat)abstract
- In 1735 Carolus Linnaeus wrote that quinine was the preferred treatment for malaria but that the bark of the ash (Fraxinus excelsior) and worm-wood (Artemisia absinthium) also had effects on the disease. We here report that lipo- and hydrophilic extracts of the bark of the ash inhibit the in vitro growth of the asexual stages of P. falciparum. The data suggests that the knowledge of the treatment of malaria was already available in Europe some 300 years ago.

Tidskriftsartikel (refereegranskat)abstract
- Invasive disease caused by antibiotic resistant pneumococci is a worldwide problem. All invasive pneumococcal strains in an area of south-west Sweden with 1.7 million inhabitants were collected prospectively during 1998-2001. Minimum inhibitory concentrations (MICs) were determined by E-test and correlated to serotypes and clinical characteristics. Of 827 strains, 744 (90%) were susceptible (S) to all agents tested and 83 (10%) were indeterminate (I) or resistant (R) to at least 1 agent. 22 isolates (2.7%) were I to penicillin (MIC >0.06 to < or = 1.0 mg/l), but none were R (MIC >1.0 mg/l). Numbers and proportions of decreased susceptibility against other agents tested were as follows: erythromycin R: 30 (3.6%), clindamycin R: 6 (0.7%), tetracycline R: 16 (1.9%), moxifloxacin R: 1 (0.1%), cotrimoxazole I: 17 (2%) and R: 31(4%). Non-susceptibility to at least 1 agent was not correlated with age, clinical manifestation, underlying diseases and outcome. The serotype distribution differed between non-susceptible and susceptible strains. The serotypes in the 7-valent pneumococcal conjugate vaccine covered 42% of all infections and 73% of those caused by non-susceptible strains. In conclusion, the impact of antibiotic resistance in invasive pneumococcal disease remains limited in south-west Sweden.

- Sequential CAT scan studies of the brain were performed in a 7-year-old boy with Listeria monocytogenes serotype 1 meningoencephalitis. The infection occurred while he was receiving maintenance chemotherapy for T-cell non-Hodgkin lymphoma. A lesion in the right hemisphere during the infection resulted in an excessive enlargement of the right ventricle 10 months later, most probably caused by arterial occlusion.

-
Tidskriftsartikel (refereegranskat)abstract
- In a 5 y retrospective follow-up study in southern Sweden of 708 adult individuals with erythema migrans as the single manifestation of Lyme borreliosis, the clinical outcome and the antibiotic treatment were studied. 80%, were treated with phenoxymethyl penicillin, 15% with doxycycline and 5% with other antibiotics. Phenoxymethyl penicillin and doxycycline were extremely effective: 98 and 94% of the individuals reported complete recovery without complications. Few individuals reported the development of new symptoms following treatment and none developed any late manifestation of Lyme borreliosis during the observation period. Thus, in the area studied the treatment of the early localized manifestation of Lyme borreliosis (erythema migrans) with antibiotics was extremely successful. The current Swedish recommendation to use phenoxymethyl penicillin, when no sign of disseminated infection or coinfection with other tick-borne pathogens is present, seems excellent.

Tidskriftsartikel (refereegranskat)abstract
- In a 5-y retrospective follow-up study in southern Sweden that initially included > 1000 individuals with previously diagnosed erythema migrans, factors that influenced the risk of reinfection with Lyme borreliosis were elucidated. The total frequency of reinfection was 4% and the number of tick bites influenced the risk of reinfection: those bitten > 10 times during the observation period had a 4-8-fold increased risk compared with those bitten < 5 times. Women manifested to a greater extent than men although both genders were bitten equally by ticks, thus indicating that women may be more susceptible to reinfection. All reinfected women were > 44 y old. The county of Kalmar including Oland was found to be highly endemic for reinfection with Lyme borreliosis. Thus the number of tick bites, gender, age and study area influenced the risk of reinfection.

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
- Pneumococci isolated from blood and cerebrospinal fluid from 1998 to 2001 in 2 counties in south-west Sweden were serotyped with the capsular reaction test. Of the 836 strains, 353 (42%), 598 (72%) and 789 (94%) belonged to serotypes included in the 7- and 11-valent pneumococcal conjugate vaccines and in the 23-valent polysaccharide vaccine, respectively. The most common serotype was type 1 (119 isolates) followed in descending frequency by serotypes 7F, 9V, 14, 4 and 12F (90-49 isolates per serotype). The coverage rates of the 7- and 11-valent conjugate vaccines among 58 strains isolated from children and adolescents 0-19 y of age were 46% and 93%, respectively. A comparison of clinical characteristics of infections caused by different serotypes showed that types 1 and 7F were less commonly associated with severe underlying diseases, that patients infected with these serotypes were younger than the average and, thus, had a lower case-fatality rate.
