Abstract
BACKGROUND It is assumed that the prevalence of hepatitis D in HBsAg-positive individuals reaches 4.5-13% in the world and on average about 3% in Europe. Data from several European countries, including Slovakia, are missing or are from an older period. METHODS We analyzed all available data on hepatitis D from Slovakia, including reports from the Slovak Public Health Authority and the results of one prospective study, and three smaller surveys. The determination of anti-HDV IgG and IgM antibodies and/or HDV RNA was used to detect hepatitis D. RESULTS In the years 2005-2022, no confirmed case of acute or chronic HDV infection was reported in Slovakia. The presented survey includes a total of 343 patients, of which 126 were asymptomatic HBsAg carriers, 33 acute hepatitis B, and 184 chronic hepatitis B cases. In a recent prospective study of 206 HBsAg-positive patients who were completely serologically and virologically examined for hepatitis B and D, only 1 anti-HDV IgG-positive and no anti-HDV IgM or HDV RNA-positive cases were detected. In other smaller surveys, two anti-HDV IgG-positive patients were found without the possibility of HDV RNA confirmation. In total, only 3 of 329 HBsAg-positive patients (0.91%) tested positive for anti-HDV IgG antibodies, and none of 220 tested positive for HDV RNA. CONCLUSION The available data show that Slovakia is one of the countries with a very low prevalence of HDV infection, reaching less than 1% in HBsAg-positive patients. Routine testing for hepatitis D is lacking in Slovakia, and therefore it is necessary to implement testing of all HBsAg-positive individuals according to international recommendations.

Abstract
Background: SEN virus (SENV) is the latest virus proposed as a cause of unknown hepatitis cases. Among nine detected genotypes of the virus, genotypes D and H are more frequent in hepatitis cases of unknown origin. The aim of this study was to determine the frequency of SENV-D and SENV-H genotypes in the sera of healthy individuals and hepatitis B and C patients. Methods: Totally, 200 serum samples from healthy individuals as well as 50 hepatitis B and 50 hepatitis C patients were collected. Anti-HCV (hepatitis C virus), anti-human immunodeficiency virus, hepatitis B surface antigen and anti-HBV (hepatitis B virus) core antigen were detected, and serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured. Viral DNA was subjected to nested PCR. Fisher's exact and unpaired ANOVA tests were used for statistical analyses. Results: SENV was detected in 90%, 66%, and 46% of the healthy individuals HBV and HCV-positive individuals, respectively. The frequency of SENV and its two genotypes were significantly lower in hepatitis B and hepatitis C patients (P<0.01). Also, the frequency of SENV-H was higher than SENV-D in all studied groups. In SENV-positive HBV patients, the level of ALT and AST enzymes were significantly less than SENV-negative patients (P<0.05). It was the same for SENV-H-negative and -positive cases. Conclusions: The levels of liver enzymes were significantly lower in HBV patients co-infected with SENV compared to HBV patients (P<0.05), indicating a positive impact of the virus in liver pathology by decreasing liver damage and thus decreasing the liver enzymes.

Prevalence and genotyping of group 3 torque teno viruses detected in health care workers in Hungary. Virus Genes 2009; 39:39-45.

Abstract
Torque teno viruses (TTVs) are classified into the Anellovirus genus of the Circoviridae family. In addition to TTV isolates, TTV genogroup 3 also includes the 8 virus strains known as SENV-A to H. In this study, the prevalence of TTV group 3 viruses and that of SENV-D and H in particular were determined among the staff of a hospital in Budapest. Viruses were genotyped using type-specific PCR primers and by cloning and sequencing of PCR products. Frequency of infection with TTV group 3 was high among both the hospital staff and the control group. Prevalence of SENV-H was similar in the two groups, but SENV-D infection was significantly more common in the study group than in controls. Sequencing of PCR products showed that viruses closely related to isolate TUS01 are common in Hungary. Several sequences could not be genotyped and may represent a previously undescribed genotype within the genogroup. TTV group 3 sequences detected in the serum samples of a symptomless health care worker were followed-up for 15 years. Some strains persisted for up to 10 years, while others caused transient infections and could be detected in only one of the samples. Results showed that TTV infection, superinfection, and viral clearance often occur over the years without apparent symptoms.
