The future interferon-free treatment of hepatitis C virus (HCV) infection could include NS3 protease inhibitors (PIs) for potent pan-genotypic effect. We studied the prevalence of pre-existing PI resistance associated amino acid variants (RAVs) in 126 treatment-naive patient samples of HCV genotypes 1a, 2b and 3a, the most common genotypes in Sweden. The(More)
The emergence of the popular, physically demanding and highly nature-interactive sport of orienteering was marked in Sweden by an elevated rate of sudden unexpected cardiac deaths in young competitors during the years 1979-92, with a common underlying cause or causes suspected. Subsequently, sera were collected during 1992-93 from the elite segment of(More)
During the period 1979-92, an increasing number of sudden unexpected cardiac deaths (SUCD) occurred in young, Swedish, male elite orienteers. Myocarditis was the most common diagnosis in the 16 victims, and in 4 cases was also associated with fatty infiltration mimicking arrhythmogenic right ventricular cardiomyopathy (ARVC). Tissues from autopsies of 5(More)
BACKGROUND Sixteen cases of sudden unexpected cardiac death, 15 males and one female, are known to have occurred among young Swedish orienteers from 1979 to 1992, of which seven cases occurred between 1989 and 1992. This is considered to be indicative of an increased death rate. RESULTS Histopathological evaluation showed myocarditis in a higher than(More)
The elite athlete has a potentially increased sensitivity to respiratory infections, rendering protective measures particularly important. Some other infections that may appear in clusters in the sports setting, such as gastroenteritis, leptospirosis, herpes simplex and viral hepatitis, also require special precautionary attention. Strenuous exercise during(More)
Methyl mercury (MeHg) has been shown to change Coxsackie virus type B3 (CB3) myocarditis in a direction compatible with the development of chronic disease. Murine models of CB3 myocarditis closely mimic the pathogenesis in humans. There are also indications that metals, such as mercury, and trace elements may interact and adversely affect viral replication(More)
Serum samples were collected from healthy blood donors in 5 regions in Sweden in 1999, i.e. from the local Blood Centres (collecting facilities) in Boden, Jönköping, Lund, Skövde, and Uppsala. In total, 498 serum samples (63% males, 37% females) were received and tested by immunofluorescence assay for antibodies against B. elizabethae, B. grahamii, B.(More)
In a search for methods for subtyping of Bartonella henselae in clinical samples, we amplified and sequenced a 701-bp region in the 3' end of the ftsZ gene in 15 B. henselae isolates derived from cats and humans in the United States and Europe. The ftsZ sequence variants that were discovered were designated variants Bh ftsZ 1, 2, and 3 and were compared(More)
Infectious myocarditis is a common condition which often passes unrecognized, and the true incidence is thus unknown. Lymphocytic myocarditis has been recorded in 1.06% of 12,747 unselected routine autopsies performed over a 10-year period. Dilated cardiomyopathy (DCM) has an estimated frequency of 7.5-10% per 100,000 inhabitants per year. Overall, the(More)
During the years 1979-1992 an accumulation of sudden unexpected cardiac deaths (SUD) occurred among young Swedish orienteers. A reevaluation of material saved from 16 autopsies was undertaken. Myocarditis was most frequent. It was found in different stages in the majority of cases, indicating subacute or chronic disease with ongoing reparative processes.(More)
