Direct-acting antivirals in women of reproductive age infected with hepatitis C virus. J Viral Hepat 2024; 31:309-319. [PMID: 38483035 DOI: 10.1111/jvh.13936] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 02/16/2024] [Accepted: 03/03/2024] [Indexed: 05/18/2024]
Abstract
Eliminating hepatitis C virus (HCV) infection in the population of women of reproductive age is important not only for the health of women themselves but also for the health of newborns. This study aimed to evaluate the implementation of this goal by analysing the effectiveness of contemporary therapy in a large cohort from everyday clinical practice along with identifying factors reducing therapeutic success. The analysed population consisted of 7861 patients, including 3388 women aged 15-49, treated in 2015-2022 in 26 hepatology centres. Data were collected retrospectively using a nationwide EpiTer-2 database. Females were significantly less often infected with HCV genotype 3 compared to males (11.2% vs. 15.7%) and less frequently showed comorbidities (40.5% vs. 44.2%) and comedications (37.2% vs. 45.2%). Hepatocellular carcinoma, liver transplantation, HIV and HBV coinfections were reported significantly less frequently in women. Regardless of the treatment type, females significantly more often reached sustained virologic response (98.8%) compared to males (96.8%). Regardless of gender, genotype 3 and cirrhosis were independent factors increasing the risk of treatment failure. Women more commonly reported adverse events, but death occurred significantly more frequently in men (0.3% vs. 0.1%), usually related to underlying advanced liver disease. We have demonstrated excellent effectiveness and safety profiles for treating HCV infection in women. This gives hope for the micro-elimination of HCV infections in women, translating into a reduced risk of severe disease in both women and their children.

Abstract
BACKGROUND The introduction of direct-acting antivirals (DAAs) with their effectiveness and safety has revolutionized the approach to treating hepatitis C virus (HCV) infections. Nevertheless, elderly patients have often been excluded from clinical trials, so the results of real-world studies are particularly important in the context of the geriatric population. The study aimed to analyze the effectiveness and safety of antiviral DAA treatment in HCV-infected patients over the age of 65, with notable inclusion of those over the age of 85. METHODS The analyzed patients were divided by age into three groups: group A (65-74 years), group B (75-84 years) and group C (85 years or older). Patients started DAA based therapy at 22 hepatology centers between July 2015 and December 2022. RESULTS A total of 3505 elderly patients were included in the analysis, and this group consisted of 2501 patients in group A, 893 in group B, and 111 in group C. The study population, regardless of age, was dominated by women. Patients had a high prevalence of comorbidities (84.9%, 92.2%, and 93.7%, respectively) as well as a high rate of concomitant medications. The sustained virological response was 97.9% in groups A and B and 100% in group C. The therapy was well-tolerated, with a comparable safety profile observed in all analyzed groups. CONCLUSIONS DAA-based therapies are highly effective and well tolerated by the elderly patients, including those over 85. Age should not be a barrier to treatment, but careful management is necessary.

Abstract
OBJECTIVES The assessment of the prevalence of anti-SARS-CoV-2 antibodies in various professional groups is very important. Hence, the purpose of the following study was to analyze the seroprevalence of anti-SARS-CoV-2 antibodies among employees performing both medical and nonmedical professions before the launch of SARS-CoV-2 vaccination. MATERIAL AND METHODS The study was conducted among employers of 1 of the institutions: The Provincial Specialist Hospital of Władysław Biegański in Łódź, Poland, Radio Łódź and the Border Guards of Łódź Airport. Blood samples were collected in December 2020-February 2021. Patients were screened for the presence of SARS-CoV-2 antibodies. Simultaneously respondents were asked to complete a self-designed questionnaire including demographic data, detailed profession, history of SARS-CoV-2 infection and willingness to be vaccinated against COVID-19. RESULTS Seroprevalence was significantly higher in the group of rural residents (p < 0.012), participants who declared previous COVID-19 infection (p < 0.001) and healthcare workers (HCWs) (p = 0.002), especially nurses (35.5%, p = 0.003) and medics worked in areas dedicated to COVID-19 than in other specialties (38.7% vs. 26.8%, respectively, p = 0.017). There was no association between the presence of antibodies and the gender (p = 0.118), age (p = 0.559) or BMI (p = 0.998). CONCLUSIONS Healthcare workers, in particular nurses, are at high risk of contracting COVID-19 in the workplace. Occupational infections can occur during occur not only during contact with the patient, but also with members of the medical team who do not show typical symptoms of the disease. Shortages in medical staff may also increase the number of infections among HCWs. Medical and hospital staff providing health services during the COVID-19 epidemic in Poland, may seek compensation in the event of consequences related to SARS-CoV-2 infection. The effectiveness of education and self-discipline in complying to safety rules among HCWs should also be constantly monitored. Int J Occup Med Environ Health. 2023;36(5):643-55.

Comparison of Post-Vaccination Response between mRNA and Vector Vaccines against SARS-CoV-2 in Terms of Humoral Response after Six Months of Observation. Vaccines (Basel) 2023; 11:1625. [PMID: 37897027 PMCID: PMC10611196 DOI: 10.3390/vaccines11101625] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Revised: 10/15/2023] [Accepted: 10/20/2023] [Indexed: 10/29/2023] Open
Abstract
BACKGROUND The emergence of the SARS-CoV-2 (COVID-19) pandemic has accelerated work on the creation of effective vaccines, both in terms of previously known vector vaccines and new-generation (mRNA) vaccines. The scientific research on vaccination against COVID-19 infection is limited; therefore, understanding how the immune system responds to vaccines is critical. In our study, we conducted a long-term analysis of the presence and persistence of the immune response via chemiluminescence, analyzing the level of IgG antibodies and neutralizing antibodies in subjects vaccinated with two types of mRNA (Comirnaty) and vector (Vaxzevria) vaccines. MATERIALS AND METHODS Healthcare workers and a group of teachers were recruited for this study according to the 2021 government-launched vaccination calendar. They received two doses of the Comirnaty or Vaxzevria vaccine. SRBD (spike-receptor binding domain) IgG antibody levels were measured monthly for 6 consecutive months with a chemiluminescent assay (CLIA) and neutralizing antibodies for two periods-1 and 5 months from the completion of the vaccination course. RESULTS 168 people were recruited for this study: 135 people for the mRNA vaccine group and 33 people for the vector vaccine group. Comparing the serum IgG levels between the two types of vaccines, a significant difference in median values can be noted at all time points. In consecutive months, the mRNA-vaccinated group exhibited significantly higher SRBD levels compared to the vector group, with peak concentrations at one month after the complete vaccination cycle (745 AU/mL vs. 15.44 AU/mL; p < 0.001). Peak antibody concentration for the vector vaccine was observed one month later, at the third follow-up visit; however, the median IgG concentration was almost 7.7 times higher for the Comirnaty group. Both products were effective in stimulating neutralizing antibody production after vaccination. Higher median values were observed for the mRNA vaccines in both evaluations. At first evaluation, the median value for NA concentration in the Comirnaty group was 6 times higher than in the Vaxzevria group (median value 12.23 [IQR 27.3] vs. 1.7 [IQR 3.3]; p < 0.001. CONCLUSIONS People vaccinated with the mRNA vaccine (Comirnaty) showed a stronger immune response to the vaccination than the group of people administered the vector vaccine (Vaxzevria). The Comirnaty group showed higher levels of IgG, including neutralizing antibodies, at all time points during the follow-up period, and this was independent of having had a SARS-CoV-2 infection. A natural decrease in antibody levels was seen within 6 months. A booster vaccination may be required. No serious side effects were observed in either group.

Pangenotypic triple versus double therapy in HCV-infected patients after prior failure of direct-acting antivirals. Clin Exp Hepatol 2023; 9:193-201. [PMID: 37790681 PMCID: PMC10544061 DOI: 10.5114/ceh.2023.130935] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Accepted: 08/20/2023] [Indexed: 10/05/2023] Open
Abstract
Aim of the study Despite the excellent effectiveness of direct-acting antivirals (DAA) in the treatment of hepatitis C virus (HCV) infection, still a few percent of patients fail therapy. The study aimed to determine the effectiveness of triple vs double rescue treatment in such a population. Material and methods The study included all consecutive DAA-experienced patients retreated with pangenotypic options from the EpiTer-2 database, a retrospective national multicenter real-world project evaluating antiviral treatment in HCV-infected patients in 2015-2023. Results The studied population consisted of 269 patients, of whom 208 were treated with the double (P2) and 61 with the triple (P3) pangenotypic option. No statistically significant differences were found between these subpopulations, except a significantly more frequent history of liver transplantation in the P3 group (6.6% vs. 0.5%, p = 0.01). In the P2 group, two-thirds of patients were treated with velpatasvir/sofosbuvir, while in the P3 group the majority of patients received a combination of velpatasvir/sofosbuvir/voxilaprevir. Virological response at the end of therapy was comparable in both analyzed subpopulations, but the sustained virologic response (SVR) rate was significantly higher in triple retherapy, 98.3% vs. 88.7%, p = 0.02, calculated after exclusion of patients lost to follow-up. Lower SVR was achieved in genotype 3-infected men with cirrhosis, 88.9% and 80% in P3 and P2, respectively. Conclusions A comparison of double and triple pangenotypic retherapy in patients after failure of DAA therapy showed a higher sustained virological response in the triple option with a comparable response at the end of therapy. The factors reducing the chances of cure were cirrhosis, genotype 3 infection and male gender.

Abstract
This study aimed to compare the clinical picture of COVID-19 in the initial and later period of Omicron dominance and to identify populations still at risk. A retrospective comparison of the clinical data of 965 patients hospitalized during the early period of Omicron's dominance (EO, January-June 2022) with 897 patients from a later period (LO, July 2022-April 2023) from the SARSTer database was performed. Patients hospitalized during LO, compared to EO, were older, had a better clinical condition on admission, had a lower need for oxygen and mechanical ventilation, had less frequent lung involvement in imaging, and showed much faster clinical improvement. Moreover, the overall mortality during EO was 14%, higher than that in LO-9%. Despite the milder course of the disease, mortality exceeding 15% was similar in both groups among patients with lung involvement. The accumulation of risk factors such as an age of 60+, comorbidities, lung involvement, and oxygen saturation <90% resulted in a constant need for oxygen in 98% of patients, an 8% risk of mechanical ventilation, and a 30% mortality rate in the LO period. Multiple logistic regression revealed lower odds of death during the LO phase. Despite the milder course of infections caused by the currently dominant subvariants, COVID-19 prophylaxis is necessary in people over 60 years of age, especially those with comorbidities, and in the case of pneumonia and respiratory failure.

Real-world effectiveness and safety of direct-acting antivirals in hepatitis C virus patients with mental disorders. World J Gastroenterol 2023; 29:4085-4098. [PMID: 37476581 PMCID: PMC10354581 DOI: 10.3748/wjg.v29.i25.4085] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 04/01/2023] [Accepted: 04/28/2023] [Indexed: 06/28/2023] Open
Abstract
BACKGROUND It is estimated that 58 million people worldwide are infected with the hepatitis C virus (HCV). Patients with severe psychiatric disorders could not be treated with previously available interferon-based therapies due to their unfavorable side effect profile. This has changed with the introduction of direct-acting antivirals (DAA), although their real-life tolerance and effectiveness in patients with different psychiatric disorders remain to be demonstrated. AIM To evaluate the effectiveness and safety of DAA in patients with various mental illnesses. METHODS This was a retrospective observational study encompassing 14272 patients treated with DAA for chronic hepatitis C in 22 Polish hepatology centers, including 942 individuals diagnosed with a mental disorder (anxiety disorder, bipolar affective disorder, depression, anxiety-depressive disorder, personality disorder, schizophrenia, sleep disorder, substance abuse disorder, and mental illness without a specific diagnosis). The safety and effectiveness of DAA in this group were compared to those in a group without psychiatric illness (n = 13330). Antiviral therapy was considered successful if serum ribonucleic acid (RNA) of HCV was undetectable 12 wk after its completion [sustained virologic response (SVR)]. Safety data, including the incidence of adverse events (AEs), serious AEs (SAEs), and deaths, and the frequency of treatment modification and discontinuation, were collected during therapy and up to 12 wk after treatment completion. The entire study population was included in the intent-to-treat (ITT) analysis. Per-protocol (PP) analysis concerned patients who underwent HCV RNA evaluation 12 wk after completing treatment. RESULTS Among patients with mental illness, there was a significantly higher percentage of men, treatment-naive patients, obese, human immunodeficiency virus and hepatitis B virus-coinfected, patients with cirrhosis, and those infected with genotype 3 (GT3) while infection with GT1b was more frequent in the population without psychiatric disorders. The cure rate calculated PP was not significantly different in the two groups analyzed, with a SVR of 96.9% and 97.7%, respectively. Although patients with bipolar disorder achieved a significantly lower SVR, the multivariate analysis excluded it as an independent predictor of treatment non-response. Male sex, GT3 infection, cirrhosis, and failure of previous therapy were identified as independent negative predictors. The percentage of patients who completed the planned therapy did not differ between groups with and without mental disorders. In six patients, symptoms of mental illness (depression, schizophrenia) worsened, of which two discontinued treatments for this reason. New episodes of sleep disorders occurred significantly more often in patients with mental disorders. Patients with mental illness were more frequently lost to follow-up (4.2% vs 2.5%). CONCLUSION DAA treatment is safe and effective in HCV-infected patients with mental disorders. No specific psychiatric diagnosis lowered the chance of successful antiviral treatment.

Changes in characteristics of patients with hepatitis C virus-related cirrhosis from the beginning of the interferon-free era. World J Gastroenterol 2023; 29:2015-2033. [PMID: 37155527 PMCID: PMC10122793 DOI: 10.3748/wjg.v29.i13.2015] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 01/16/2023] [Accepted: 03/20/2023] [Indexed: 04/06/2023] Open
Abstract
BACKGROUND Nearly 290000 patients with chronic hepatitis C die annually from the most severe complications of the disease. One of them is liver cirrhosis, which occurs in about 20% of patients chronically infected with the hepatitis C virus (HCV). Direct-acting antivirals (DAAs), which replaced interferon (IFN)-based regimens, significantly improved the prognosis of this group of patients, increasing HCV eradication rates and tolerability of therapy. Our study is the first to assess changes in patient profile, effectiveness, and safety in the HCV-infected cirrhotic population in the IFN-free era.
AIM To document changes in patient characteristics and treatment regimens along with their effectiveness and safety profile over the years.
METHODS The studied patients were selected from 14801 chronically HCV-infected individuals who started IFN-free therapy between July 2015 and December 2021 in 22 Polish hepatology centers. The retrospective analysis was conducted in real-world clinical practice based on the EpiTer-2 multicenter database. The measure of treatment effectiveness was the percentage of sustained virologic response (SVR) calculated after excluding patients lost to follow-up. Safety data collected during therapy and the 12-wk post-treatment period included information on adverse events, including serious ones, deaths, and treatment course.
RESULTS The studied population (n = 3577) was balanced in terms of gender in 2015-2017, while the following years showed the dominance of men. The decline in the median age from 60 in 2015-2016 to 57 years in 2021 was accompanied by a decrease in the percentage of patients with comorbidities and comedications. Treatment-experienced patients dominated in 2015-2016, while treatment-naive individuals gained an advantage in 2017 and reached 93.2% in 2021. Genotype (GT)-specific options were more prevalent in treatment in 2015-2018 and were supplanted by pangenotypic combinations in subsequent years. The effectiveness of the therapy was comparable regardless of the period analyzed, and patients achieved an overall response rate of 95%, with an SVR range of 72.9%-100% for the different therapeutic regimens. Male gender, GT3 infection, and prior treatment failure were identified as independent negative predictors of therapeutic success.
CONCLUSION We have documented changes in the profile of HCV-infected cirrhotic patients over the years of accessibility to changing DAA regimens, confirming the high effectiveness of IFN-free therapy in all analyzed periods.

Abstract
Direct-acting antivirals (DAA) regimens have provided hope for eliminating hepatitis C virus (HCV) infection. Patients following ineffective therapy with DAA, especially those previously treated with inhibitors of non-structural protein 5A (NS5A), remain a challenge. The study aimed to assess the effectiveness of DAA pangenotypic options in patients after failure of NS5A containing genotype-specific regimens. The analysis included 120 patients selected from the EpiTer-2 database with data on 15675 HCV-infected individuals treated with IFN-free therapies from 1 July 2015 to 30 June 2022 at 22 Polish hepatology centres. The majority of them were infected with genotype (GT) 1b (85.8%) and one-third was diagnosed with fibrosis F4. Among the rescue pangenotypic regimens, the most commonly used was the sofosbuvir/velpatasvir (SOF/VEL) ± ribavirin (RBV) combination. The sustained virologic response, which was a measure of treatment effectiveness, was achieved by 102 patients, resulting in cure rate of 90.3% in the per protocol analysis. All 11 non-responders were infected with GT1b, 7 were diagnosed with cirrhosis, and 9 were treated with SOF/VEL±RBV. We demonstrated the high effectiveness of the pangenotypic rescue options in patients after genotype specific NS5A-containing regimens failures, identifying cirrhosis as a negative prognostic factor of treatment effectiveness.

Abstract
The recommendations define the principles of diagnosis and treatment of hepatitis C virus (HCV) infection according to the latest knowledge. The main goal of the treatment of HCV infection is to eliminate the virus from the body, which in turn leads to stopping the progression or causes the regression of previously formed changes in the liver. The current version of the guidelines prioritizes pangenotypic regimens and includes guidelines for special patient populations such as children, patients with cirrhosis, human immunodeficiency virus (HIV) and hepatitis B virus (HBV) infection, patients with renal failure, liver failure and lack of response to previous therapies as well as patients in the peri-transplant period.

Abstract
INTRODUCTION Despite the overall excellent efficacy of pangenotypic direct-acting antiviral (DAA) options, there is still a small percentage of patients with hepatitis C virus (HCV) infection who do not respond to therapy. OBJECTIVES This analysis was designed to evaluate the effectiveness of pangenotypic retreatment in pangenotypic failures. PATIENTS AND METHODS The study included patients treated with the pangenotypic regimen selected from the EpiTer-2 database, real-world project evaluating DAA-based treatment in Poland. RESULTS Among 15,123 patients, 4,345 received one course of pangenotypic treatment (PAN-group) and 48 patients were retreated with pangenotypic regimens after pangenotypic failure (PAP-group). Patients from PAP-group were more often males (79% vs 53%, P<0.001), had higher BMI (27.5 IQR:25.7-30.1 vs 25.7 IQR: 22.9-28.7 kg/m2, P<0.001), were more often infected with genotype (GT) 3 (58% vs 27%, P<0.001) and more frequently had liver cirrhosis (46% vs 21%, P<0.001) compared with the PAN-group. Importantly, no significant difference in treatment effectiveness was found between PAP and PAN-groups with sustained virologic response (SVR) rate of 89.6% vs 93.7% (P=0.39) in intent-to-treat and 91.5% vs 97.6% (P=0.17) in per protocol analysis. The selection of a specific retherapy regimen did not affect SVR. CONCLUSIONS Our study demonstrated the excellent effectiveness of pangenotypic regimens and that most DAA non-responders could be successfully retreated with next pangenotypic regimen. The best retreatment strategy is a triple pangenotypic regimen, especially in patients with unfavorable response factors such as GT3 infection, cirrhosis, and male sex.

Abstract
BACKGROUND The revolution in treatment of patients with chronic hepatitis C virus (HCV) infection dates back to the introduction of direct-acting antivirals (DAAs). The increase in efficacy was most pronounced in patients infected with genotype (GT) 1b, as this was the most poorly responsive population to treatment during the interferon era.
AIM To identify the most effective interferon-free therapy for GT1b-infected patients and to determine positive and negative predictors of virological response.
METHODS This real-world retrospective analysis included patients chronically infected with GT1b HCV whose data were obtained from the multicenter observational EpiTer-2 database. Treatment effectiveness was evaluated for each therapeutic regimen as the percentage of sustained virological responses (SVR). Assessment of the safety was based on the evaluation of the course of therapy, the occurrence of adverse events including serious ones, deaths during treatment and in the post 12-wk follow-up period.
RESULTS The studied population consisted of 11385 patients with a mean age of 53 ± 14.8 years and a female predominance (53.4%). The majority of them were treatment-naïve (74.6%) and patients with cirrhosis accounted for 24.3%. Of the DAA regimens used, 76.9% were GT-specific with ombitasvir/paritaprevir/ritonavir + dasabuvir ± ribavirin being the most used option (32.4%). A total of 10903 patients responded to treatment resulting in a 98.1% in the per-protocol analysis after excluding 273 patients without SVR data. The effectiveness of all regimens exceeded 90% and the highest SVR of 98.9% was achieved in patients treated with a combination of glecaprevir/pibrentasvir. Logistic regression analyses showed that the virologic response was independently associated with female sex [odds ratio (OR) = 1.67], absence of decompensated cirrhosis at baseline (OR = 2.42) and higher baseline platelets (OR = 1.004 per 1000/μL increase), while the presence of human immunodeficiency virus (HIV) coinfection significantly decreased the odds of response (OR = 0.39). About 95%-100% of patients completed therapy irrespective of the drug regimen. At least one adverse effect occurred in 10.9%-36.3% and most of them were mild. No treatment related deaths have been reported.
CONCLUSION We documented very high effectiveness and a good safety profile across all DAA regimens. Positive predictors of SVR were female sex, absence of decompensated cirrhosis at baseline and higher platelet count while HIV coinfection reduced the effectiveness.

Remdesivir Decreases Mortality in COVID-19 Patients with Active Malignancy. Cancers (Basel) 2022; 14:cancers14194720. [PMID: 36230641 PMCID: PMC9563758 DOI: 10.3390/cancers14194720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 09/19/2022] [Accepted: 09/23/2022] [Indexed: 12/15/2022] Open
Abstract
Data on the use of remdesivir, the first antiviral agent against SARS-CoV-2, are limited in oncologic patients. We aimed to analyze contributing factors for mortality in patients with malignancies in the real-world CSOVID-19 study. In total, 222 patients with active oncological disorders were selected from a nationwide COVID-19 study of 4890 subjects. The main endpoint of the current study was the 28-day in-hospital mortality. Approximately half of the patients were male, and the majority had multimorbidity (69.8%), with a median age of 70 years. Baseline SpO2 < 85% was observed in 25%. Overall, 59 (26.6%) patients died before day 28 of hospitalization: 29% due to hematological, and 20% due to other forms of cancers. The only factor increasing the odds of death in the multivariable model was eGFR < 60 mL/min/m2 (4.621, p = 0.02), whereas SpO2 decreased the odds of death at baseline (0.479 per 5%, p = 0.002) and the use of remdesivir (0.425, p = 0.03). This study shows that patients with COVID-19 and malignancy benefit from early remdesivir therapy, resulting in a decrease in early mortality by 80%. The prognosis was worsened by low glomerular filtration rate and low peripheral oxygen saturation at baseline underlying the role of kidney protection and early hospitalization.

Hepatitis C Infection as a Risk Factor for Hypertension and Cardiovascular Diseases: An EpiTer Multicenter Study. J Clin Med 2022; 11:5193. [PMID: 36079122 PMCID: PMC9456581 DOI: 10.3390/jcm11175193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2022] [Revised: 08/17/2022] [Accepted: 08/29/2022] [Indexed: 11/21/2022] Open
Abstract
Hepatitis C infection is one of the main reasons for liver cirrhosis and hepatocellular carcinoma. In recent years, more and more is being heard about extrahepatic manifestations of the hepatitis C infection including its possible influence on the development of hypertension and cardiovascular diseases. In the given work, the frequency analysis of the incidence of hypertension and cardiovascular diseases among 2898 HCV-infected patients treated in Poland and the assessment of their relevance to the HCV genotype and the progression of liver fibrosis can be found. The prevalence of hypertension in the group of analyzed patients was 39% and was significantly associated with old age (OR = 1.08 (1.07-1.08)) and female sex, as well as the progression of liver fibrosis (OR = 1.54 (1.29-1.85)). Hypertension was found in 47.6% of patients with F4 fibrosis, 42.1% of patients with F3 fibrosis, and 25% of patients with F1 fibrosis. The incidence of cardiovascular disease in the studied group of patients was as follows: all incidents, 131 (4.52%); including ischemic heart disease 104, (3.95%); stroke, 2 (0.07%); atherosclerosis, 21 (0.72%); and aneurysms, 4 (0.14%). The obtained results prove that the prevalence of cardiovascular diseases is significantly associated with the advanced age of patients and the progression of liver fibrosis. The relevance of sex and the HCV genotype to the prevalence frequency of cardiovascular diseases in the study group has not been proven. This being the case, no differences in the frequency of their incidence depending on the HCV genotype, including genotype 3, was found. Hepatitis C infection as a non-classical risk factor for cardiovascular disease and hypertension does require further studying.

The association of airborne particulate matter and benzo[a]pyrene with the clinical course of COVID-19 in patients hospitalized in Poland. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2022; 306:119469. [PMID: 35580710 PMCID: PMC9106990 DOI: 10.1016/j.envpol.2022.119469] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Revised: 05/02/2022] [Accepted: 05/09/2022] [Indexed: 05/06/2023]
Abstract
Air pollution can adversely affect the immune response and increase the severity of the viral disease. The present study aimed to explore the relationship between symptomatology, clinical course, and inflammation markers of adult patients with coronavirus disease 2019 (COVID-19) hospitalized in Poland (n = 4432) and air pollution levels, i.e., mean 24 h and max 24 h level of benzo(a)pyrene (B(a)P) and particulate matter <10 μm (PM10) and <2.5 μm (PM2.5) during a week before their hospitalization. Exposures to PM2.5 and B(a)P exceeding the limits were associated with higher odds of early respiratory symptoms of COVID-19 and hyperinflammatory state: interleukin-6 > 100 pg/mL, procalcitonin >0.25 ng/mL, and white blood cells count >11 × 103/mL. Except for the mean 24 h PM10 level, the exceedance of other air pollution parameters was associated with increased odds for oxygen saturation <90%. Exposure to elevated PM2.5 and B(a)P levels increased the odds of oxygen therapy and death. This study evidences that worse air quality is related to increased severity of COVID-19 and worse outcome in hospitalized patients. Mitigating air pollution shall be an integral part of measures undertaken to decrease the disease burden during a pandemic of viral respiratory illness.

Abstract
The emergence of a highly transmissible and a more pathogenic B.1.617.2 (delta) variant of SARS-CoV-2 has brought concern over COVID-19 vaccine efficacy and the increased risk of severe breakthrough infections. The objective of this study was to assess the frequency and the clinical characteristics of severe breakthrough COVID-19 cases recorded in 10 Polish healthcare units between 1 June and 31 December 2021, a period during which a rapid surge in the share of B.1.617.2 infections was seen, while a significant number of populations were already fully vaccinated. Overall, 723 individuals who completed the initial vaccination regime (fully vaccinated group) and an additional 18 who received a booster dose were identified—together, they represented 20.8% of all the COVID-19 patients hospitalized during the same period in the same healthcare institutions (0.5% in the case of a group that received a booster dose). Although laboratory and clinical parameters did not differ between both groups, patients who received a booster tended to have lower CRP, IL-6, PCT, and d-dimer levels and they required oxygen therapy less frequently. The most common early COVID-19 symptoms in the studied group were fatigue, cough, fever (>38 °C), and dyspnea. Individuals with no detectable anti-spike IgG antibodies constituted 13%; the odds of being a humoral non-responder to the vaccine were increased in patients aged >70 years. Fully vaccinated patients hospitalized after more than 180 days from the last vaccine dose were significantly older and they were predominantly represented by individuals over 70 years and with comorbidities, particularly cardiovascular disease. Contrary to mRNA vaccines, most patients vaccinated with adenoviral vector vaccines were infected within six months. A total of 102 fatal cases (14% of all deaths among vaccinated individuals; 0.7% in the case of a group that received a booster dose) were recorded, representing 17.6% of all the COVID-19 fatalities recorded in June−December 2021 in the considered healthcare units. The odds of death were significantly increased in men, individuals aged >70 years, patients with comorbidities, and those identified as humoral non-responders to vaccination; in fully vaccinated patients the odds were also increased when the second vaccine dose was given >180 days before the first COVID-19 symptoms. The mortality rate in immunocompromised subjects was 19%. The results indicate that compared to vaccinated individuals, severe COVID-19 and deaths in the unvaccinated group were significantly more prevalent during the B.1.617.2-dominated wave in Poland; and, it highlight the protective role of a booster dose, particularly for more vulnerable individuals.

Abstract
The first Polish recommendations regarding the management of patients with COVID-19 were published by the Polish Society of Epidemiologists and Infectiologists (PTEiLChZ) on March 31, 2020, and the last annex was dated November 12, 2021. The ongoing state of pandemic, the emergence of new variants of the virus, and the availability of new drugs necessitate their updating. Changes introduced in the current version of recommendations for the management of COVID-19 comprised the possibility of using remedesivir in an outpatient setting, previously reserved for inpatient treatment, as well as other antiviral drugs-molnupiravir and nirmatrelvir / ritonavir. We revised the possibility of using monoclonal antibodies due to the resistance of the currently dominant Omicron variant. Anakinra, an antagonist of interleukin 1 receptors, has been added as a treatment option in advanced stages of the disease, and the recommended daily dose of glucocorticosteroids used in the most severe forms of COVID-19 has been increased. Information on vaccination and pre-exposure prophylaxis in specific populations has also been updated.

Abstract
The introduction of the direct-acting antivirals (DAA) has substantially improved the effectiveness of the therapy in patients with chronic hepatitis C. We aimed to compare the efficacy of pangenotypic and genotype-specific DAA in the cohort of genotype (GT) four patients with HCV monoinfection and HIV coinfection. A total of 662 GT4-infected patients treated in 2015–2020—of whom 168 (25.3%) were coinfected with HIV, selected from the retrospective EpiTer-2 database—were enrolled in the analysis. Among HIV-coinfected patients, 54% (90) were treated with genotype-specific regimens and 46% (78) with pangenotypic options, while among HCV-monoinfected patients, the rates were 72% and 28%, respectively. Significantly higher rate of males (67.9% vs. 57.7%, p = 0.01), a lower rate of liver cirrhosis (10.2% vs. 18.1%, p = 0.02), and higher of treatment-naïve patients (87.5% vs. 76.7%, p = 0.003) were documented in the HIV coinfected population. The overall sustained virologic response after exclusion of non-virologic failures was achieved in 98% with no significant difference between HIV-positive and HIV-negative patients, 96.2% vs. 98.5%, respectively. While the genotype-specific regimens resulted in a similar cure rate regardless of the HIV status, the pangenotypic options were more efficacious in patients with HCV monoinfection (99.3% vs. 94.4%, p = 0.05). Hereby, we demonstrated the high effectiveness and good safety profile of the DAA therapy in the population of HCV GT4 infected patients with HIV coinfection supporting the current recommendations to treat HCV/HIV coinfected patients with the same options as those with HCV monoinfection.

Efficacy of 8- versus 12-week treatment with ledipasvir/sofosbuvir in chronic hepatitis C patients eligible for 8-week regimen in a real-world setting. Arch Med Sci 2022; 18:1460-1466. [PMID: 36457986 PMCID: PMC9710286 DOI: 10.5114/aoms.2019.86569] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2019] [Accepted: 06/05/2019] [Indexed: 11/17/2022] Open
Abstract
INTRODUCTION Non-cirrhotic treatment-naive hepatitis C patients infected with genotype 1 can be treated with ledipasvir/sofosbuvir (LDV/SOF) for 8 weeks, but in practice this regimen is frequently extended up to 12 weeks at least in part due to insufficient real-world data supporting shortening of treatment. The aim of our study was to compare 8- and 12-week regimens' efficacy in patients eligible for 8-week therapy in a real-world setting. MATERIAL AND METHODS Data of HCV genotype 1 infected patients treated with LDV/SOF between 2015 and 2018 included in the EpiTer-2 database were analyzed with respect to patients' characteristics and length of treatment. RESULTS Among a total of 1718 patients treated with LDV/SOF, 679 were included in the analysis, 238 (35%) received 8-week regimen, whereas 441 were treated for 12 weeks although they fulfilled the criteria for a shorter course. The majority of patients were infected with genotype 1b (89%) and demonstrated minimal fibrosis (55%). The 12-week regimen was assigned significantly more frequently to patients with comorbidities, concomitant medications and advanced liver fibrosis. The sustained virologic response rate was similar after 8 (98%) and 12 (97%) weeks of therapy according to intent-to-treat analysis and reached 99% in both groups after exclusion of patients lost to follow-up. CONCLUSIONS We confirmed high effectiveness regardless of treatment duration with LDV/SOF in non-cirrhotics infected with HCV genotype 1 eligible for the 8-week regimen according to the current label. This real-world study also demonstrated no need for addition of ribavirin (RBV) in this population and showed that shortening of treatment significantly improves the safety profile of LDV/SOF medication.

Demographic and Clinical Overview of Hospitalized COVID-19 Patients during the First 17 Months of the Pandemic in Poland. J Clin Med 2021; 11:jcm11010117. [PMID: 35011858 PMCID: PMC8745464 DOI: 10.3390/jcm11010117] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Revised: 12/17/2021] [Accepted: 12/23/2021] [Indexed: 11/16/2022] Open
Abstract
Long-term analyses of demographical and clinical characteristics of COVID-19 patients can provide a better overview of the clinical course of the disease. They can also help understand whether changes in infection symptomatology, disease severity, and outcome occur over time. We aimed to analyze the demographics, early symptoms of infection, laboratory parameters, and clinical manifestation of COVID-19 patients hospitalized during the first 17 months of the pandemic in Poland (March 2020-June 2021). The patients' demographical and clinical data (n = 5199) were extracted from the national SARSTer database encompassing 30 medical centers in Poland and statistically assessed. Patients aged 50-64 were most commonly hospitalized due to COVID-19 regardless of the pandemic period. There was no shift in the age of admitted patients and patients who died throughout the studied period. Men had higher C-reactive protein and interleukin-6 levels and required oxygenation and mechanical ventilation more often. No gender difference in fatality rate was seen, although the age of males who died was significantly lower. A share of patients with baseline SpO2 < 91%, presenting respiratory, systemic and gastrointestinal symptoms was higher in the later phase of a pandemic than in the first three months. Cough, dyspnea and fever were more often presented in men, while women had a higher frequency of anosmia, diarrhea, nausea and vomiting. This study shows some shifts in SARS-CoV-2 pathogenicity between March 2020 and July 2021 in the Polish cohort of hospitalized patients and documents various gender-differences in this regard. The results represent a reference point for further analyses conducted under the dominance of different SARS-CoV-2 variants.

Abstract
The current study aimed to determine to what extent prior COVID-19 infection affects the response of specific antibodies following vaccination. The study involved 173 healthcare professionals who completed the two-dose vaccination course with BNT162b2, including 40 who previously experienced clinical COVID-19. The levels of anti-SARS-CoV-2 S1S2 IgG (anti-S) and, in some cases, anti-SARS-CoV-S-RBD IgG (anti-S-RBD) were determined six months after complete vaccination. A level exceeding the cut-off values for both anti-S and anti-S-RBD was observed in 100% of subjects, but after setting the analysis to 5- and 10-fold cut-off levels, the percentage of subjects meeting this criterion was significantly higher for anti-S-RBD. The 100-fold cut-off level was achieved by only 21% and 16% for anti-S and anti-S-RBD, respectively. Anti-S and anti-S-RBD levels above ten times the positive cut-off were respectively observed in 91% and 100% individuals with a history of COVID-19, while among those without COVID-19, these values were 64% and 90%, respectively. Significantly higher incidence of values above 10 and 100 times the cut-off became apparent among people with a history of COVID-19. In conclusion, vaccination against COVID-19 following infection with the disease provides higher levels of specific antibodies 6 months after vaccination than those of individuals without a history of the disease, which supports the use of a booster dose, particularly for those who have not experienced SARS-CoV-2 infection.

Abstract
BACKGROUND AND AIMS The aim of this study was to assess the real-life effectiveness and safety of direct acting antivirals (DAAs) in patients with cirrhosis and history of hepatic decompensation compared to those with compensated cirrhosis. METHOD Data of patients treated with DAAs and included in the EpiTer-2 database (N = 10 152) were collected retrospectively. The primary endpoint was sustained viral response (SVR) at 12 weeks posttreatment. Patients were also evaluated in terms of liver-related adverse events and treatment modification/discontinuation. RESULTS The overall SVR rate was 91.4% in the intent to treat (ITT) analysis and 95.2% in the per-protocol (PP) analysis (P < .001). Patients with decompensated cirrhosis had lower SVR rates compared to those with compensated cirrhosis in ITT analysis (86.4% vs 92.0%, P < .001), while not in PP analysis (92.9% vs 95.5%, P > .05). Adverse events (AE) occurred 45.6% and 29.3% of patients with decompensated and compensated cirrhosis (P < .001). Patients with decompensated cirrhosis were at higher risk of death (5.4% vs 0.9%; P < .0001) or liver decompensation (21.5% vs 1.3%; P < .0001). Treatment with protease inhibitors was not associated with hepatic decompensation (P = .3). Only 82.6% of patients with decompensated cirrhosis completed DAA treatment (vs 92.8% in compensated cirrhotics; P < .0001). CONCLUSION Despite higher frequency of AE and treatment modifications, once completed, DAAs yield comparable results for patients with decompensated and compensated cirrhosis. High rate of serious adverse events in patients with advanced liver disease treated with PI may not be related to the detrimental effect of the medications, but rather to the disease itself.

Abstract
There is still limited data available from real-world experience studies on the pangenotypic regimens in patients with genotype (GT) 3 hepatitis C virus (HCV) infection and liver cirrhosis. The current study aimed to evaluate the efficacy and safety of pangenotypic regimens in this difficult-to-treat population. A total of 236 patients with mean age 52.3 ± 11.3 years and male predominance (72%) selected from EpiTer-2 database were included in the analysis; 72% of them were treatment-naïve. The majority of patients (55%) received the combination of sofosbuvir/velpatasvir (SOF/VEL), 71 without and 58 with ribavirin (RBV), whereas the remaining 107 individuals were assigned to glecaprevir/pibrentasvir (GLE/PIB). The effectiveness of the treatment following GLE/PIB and SOF/VEL regimens (96% and 93%) was higher compared to SOF/VEL + RBV option (79%). The univariate analysis demonstrated the significantly lower sustained virologic response in males, in patients with baseline HCV RNA ≥ 1,000,000 IU/mL, and among those who failed previous DAA-based therapy. The multivariate logistic regression analysis recognized only the male gender and presence of ascites at baseline as the independent factors of non-response to treatment. It should be emphasized that despite the availability of pangenotypic, strong therapeutic options, GT3 infected patients with cirrhosis still remain difficult-to-treat, especially those with hepatic impairment and DAA-experienced.

Abstract
(1) Background: Treatment of hepatitis C virus (HCV) infections with direct-acting antivirals (DAA) has demonstrated high efficacy and an excellent safety profile. The cured patients showed a sustained virological response and improved liver function, but also a continued risk of hepatocellular carcinoma (HCC) during the 2-3 years of follow-up after treatment; (2) Methods: A total of 192 patients out of 209 of the primary AMBER study were analyzed five years after treatment with ombitasvir/paritaprevir/ritonavir with or without dasabuvir and with or without ribavirin. Results: We confirmed that HCV clearance after DAA treatment is stable regardless of baseline liver fibrosis. We found that sustained virologic response is associated with a gradual but significant reduction in liver stiffness over 5 years. Liver function improved during the first 2 years of follow-up and remained stable thereafter. The risk of death due to HCC as well as death due to HCV persists through 5 years of follow-up after successful DAA treatment. However, in non-cirrhotic patients, it appears to clear up 3 years after treatment; (3) Conclusions: Monitoring for more than 5 years after curing HCV infection is necessary to assess the long-term risk of possible development of HCC, especially in patients with cirrhosis of the liver.

[PMID: 34295173 PMCID: PMC8291861 DOI: 10.2147/jir.s322645] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Accepted: 07/05/2021] [Indexed: 12/15/2022] Open
Abstract
Purpose The pathogenesis of coronavirus disease 2019 (COVID-19) is complicated, and in addition to antiviral therapy and combating coagulopathy, treatment should also include inhibition of the proinflammatory cytokines overproduction. The purpose of this study is to compare the effectiveness of tocilizumab (TCZ) and dexamethasone (DEX) administered alone or in combination in patients with severe COVID-19. Patients and Methods Patients were selected from the SARSTer database, containing 3330 individuals with COVID-19 treated between 1 March 2020 and 10 March 2021. The current study included adult patients with baseline oxygen saturation (SpO2) ≤90%, requiring regular or non-invasive high-flow oxygen supplementation. Results Among included 460 patients, 59 were treated with TCZ, 125 with TCZ and DEX, 169 with DEX, and 107 did not receive TCZ nor DEX. The groups were balanced regarding demographics, coexisting diseases, baseline SpO2, and comedications with remdesivir or low-molecular-weight heparin. The death rate of 6.8% was significantly lower in patients receiving TCZ alone than each arm (19.6%–23.1%), particularly in patients with interleukin-6 concentration exceeding 100pg/mL (5% vs 22.9%–51.7%, respectively). Analysis of clinical improvement demonstrated doubled, significantly higher rate after 21 and 28 days in patients treated with TCZ alone (60% and 75%, respectively) compared to DEX (27.6% and 37.9%, respectively). The need for mechanical ventilation was similar in all arms. Conclusion In patients with severe course of COVID-19, particularly those developing cytokine storm, administration of TCZ provides a significantly better effect than DEX regarding survival, clinical improvement, and hospital discharge rate. The combination of TCZ and DEX does not improve therapy effectiveness in patients with severe COVID-19 compared to the administration of TCZ alone.

Is an 8-week regimen of glecaprevir/pibrentasvir sufficient for all hepatitis C virus infected patients in the real-world experience? J Gastroenterol Hepatol 2021; 36:1944-1952. [PMID: 33171526 DOI: 10.1111/jgh.15337] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Revised: 10/30/2020] [Accepted: 11/03/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND AND AIMS The revolution of the antiviral treatment of hepatitis C virus (HCV) infection resulting in higher effectiveness came with the introduction of direct-acting antivirals with pangenotypic regimens as a final touch. Among them, the combination of glecaprevir (GLE) and pibrentasvir (PIB) provides the opportunity for shortening therapy to 8 weeks in the majority of patients. Because of still insufficient evaluation of this regimen in the real-world experience, our study aimed to assess the efficacy and safety of 8-week GLE/PIB in chronic hepatitis C patients depending on liver fibrosis and genotype (GT). METHODS The analysis included patients who received GLE/PIB for 8 weeks selected from the EpiTer-2 database, large retrospective national real-world study evaluating antiviral treatment in 12 584 individuals in 22 Polish hepatology centers. RESULTS A total of 1034 patients with female predominance (52%) were enrolled in the analysis. The majority of them were treatment naïve (94%), presented liver fibrosis (F) of F0-F3 (92%), with the most common GT1b, followed by GT3. The overall sustained virologic response after exclusion of nonvirologic failures was achieved in 95.8% and 98%, respectively (P = 0.19). In multivariate logistic regression HCV GT-3 (beta = 0.07, P = 0.02) and HIV infection (beta = -0.14, P < 0.001) were independent predictors of nonresponse. CONCLUSIONS We demonstrated high effectiveness of 8-week GLE/PIB treatment in a non-GT3 population irrespective of liver fibrosis stage. Comparable efficacy was achieved in non-cirrhotic patients regardless of the genotype, including GT3 HCV.

Factors influencing the failure of interferon-free therapy for chronic hepatitis C: Data from the Polish EpiTer-2 cohort study. World J Gastroenterol 2021; 27:2177-2192. [PMID: 34025072 PMCID: PMC8117732 DOI: 10.3748/wjg.v27.i18.2177] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Revised: 03/13/2021] [Accepted: 04/21/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The introduction of direct-acting antiviral drugs into clinical practice has revolutionized the treatment of chronic hepatitis C, making it highly effective and safe for patients. However, few researchers have analyzed the factors causing therapy failure in some patients.
AIM To analyze factors influencing the failure of direct antiviral drugs in the large, multicenter EpiTer-2 cohort in a real-world setting.
METHODS The study cohort consisted of patients with chronic hepatitis C treated at 22 Polish centers from 2016-2020. Data collected from the online EpiTer-2 database included the following: hepatitis C virus (HCV) genotype, stage of fibrosis, hematology and liver function parameters, Child-Turcotte-Pugh and Model for End-stage Liver Disease scores, prior antiviral therapy, concomitant diseases, and drugs used in relation to hepatitis B virus (HBV) and/or human immunodeficiency virus (HIV) coinfections. Adverse events observed during the treatment and follow-up period were reported. Both standard and machine learning methods were used for statistical analysis.
RESULTS During analysis, 12614 patients with chronic hepatitis C were registered, of which 11938 (mean age: 52 years) had available sustained virologic response (SVR) data [11629 (97%) achieved SVR and 309 (3%) did not]. Most patients (78.1%) were infected with HCV genotype 1b. Liver cirrhosis was diagnosed in 2974 patients, while advanced fibrosis (F3) was diagnosed in 1717 patients. We included patients with features of hepatic failure at baseline [ascites in 142 (1.2%) and encephalopathy in 68 (0.6%) patients]. The most important host factors negatively influencing treatment efficacy were liver cirrhosis, clinical and laboratory features of liver failure, history of hepatocellular carcinoma, and higher body mass index. Among viral factors, genotype 3 and viral load also exerted an influence on treatment efficacy. Classical statistical analysis revealed that treatment ineffectiveness seemed to be influenced by the male sex, which was not confirmed by the multivariate analysis using the machine learning algorithm (random forest). Coinfection with HBV (including patients with on-treatment reactivation of HBV infection) or HIV, extrahepatic manifestations, and renal failure did not significantly affect the treatment efficacy.
CONCLUSION In patients with advanced liver disease, individualized therapy (testing for resistance-associated variants and response-guided treatment) should be considered to maximize the chance of achieving SVR.

Abstract
BACKGROUND The exact effects of alcohol drinking on cardiac function are not clear. AIMS The determine the relationship between consumed amount of alcohol, myocardial injury, and prognosis. METHODS Myocardial function and cardiac outcomes were examined in subjects with chronic alcoholism by classical and strain echocardiographic parameters, including global (GLS) and layer-specific longitudinal strain of the endocardial (GLSendo) and epicardial (GLSepi) layer. One group of 65 alcohol-overusers (ALC), median (IQR) age 44(38-51) years, was compared with 30 controls (CG). RESULTS Median (IQR) alcohol dose (in alcohol units, 1AU = 10 gram of ethanol) per week was 30 (12-51) AU in ALC and 0 in CG, P <0.001, and the mean (SD) drinking period was 16 (9) years. ALC patients demonstrated higher left ventricular (LV) mass and impaired diastolic function. The ALC group demonstrated lower median (IQR) LV ejection fraction (EF): 52 (37-57)% vs. 60 (55-63)% (P <0.001); GLS: 17 (9-20)% vs. 19 (18-21)% (P = 0.01); absolute layer-specific strain values. GLSendo <19% and GLSepi <15% predicted worsened mid-term prognosis, as did elevated N - terminal brain natriuretic peptide (NT-proBNP) and lower EF and GLS. CONCLUSIONS Long-term alcohol overuse, even with a rather low reported median (IQR) dose of 4 (2-7) AU per day resulted in LV hypertrophy, diastolic and systolic dysfunction. Diminished GLS <18%, endocardial <19% and epicardial <15% layer strain predicted combined endpoints but did not significantly improve the prognostic power of tested models, based on NT-proBNP and EF in follow-up.

Abstract
Symptomatic Clostridium difficile infection (CDI) is an acute inflammatory disease of the gastrointestinal tract, manifesting in at least 3 unformed stools within 24 hours. Predicting factors for CDI include contact with medical care (mainly hospitalization), antibiotic therapy in the last 12 weeks, use of proton pump inhibitors (PPI), H2 blockers, cancer chemotherapy, especially in the neutropenia stage, gastrointestinal surgery, advanced age and concomitant chronic diseases (renal failure, liver failure, chronic inflammatory bowel disease - especially ulcerative bowel disease, cancer, HIV infection, cachexia and hypoalbuminaemia) and vitamin D deficiency. Clinical classification distinguishes three types of CDI - mild / moderate, severe, and fulminant. The principles of treatment of the first and subsequent CDI incidents depending on the clinical course are based on oral vancomycin. CDI is recurrent. The basis for treating CDI relapses is vancomycin administered orally at a dose of 4x125 mg for 10 days followed by concomitant vancomycin dose reduction therapy. The use of fecal microbiota transfer (FMT) in the treatment of CDI relapses is considered to be the most effective therapy for recurrent CDI. An indication for FMT is antibiotic-resistant C. difficile infection, regardless of the number of incidents CDI. The panel of tests recommended for a bacterial flora donor is presented in the recommendations.

Abstract
Rapid spread of severe acute respiratory syndrome coranovirus-2 virus (SARS-CoV-2) caused the pandemic of Coronavirus Disease 19 (COVID-19). Clinical course of the disease presents symptoms mainly from the respiratory system such as: cough, dyspnea and fever, and among some patients, can deteriorate even further to acute respiratory distress syndrome (ARDS), eventually leading to death. This outbreak, as well as previous ones (SARS, MERS) pose a significant challenge for health care managers, epidemiologists and physicians. Below we are presenting the clinical profile of the COVID-19 among special group of patients; pregnant women and newborns, who require special clinical management during hospitalization. In the summary of this manuscript, we present practical guidelines for managing pregnant women infected with SARS-CoV-2, labor and care of the newborn of a positive mother, as well as practical guidelines for COVID-19 vaccinations. It is important to stress, that this manuscript is based on information available as of December 2020.

Abstract
Background Patients who undergo hemodialysis (HD) or kidney transplantation (KTx) previously had limited possibilities for treatment of hepatitis C virus (HCV) infection. Direct-acting antivirals (DAA) give these patients a chance of virus eradication and safe transplantation. The aim of this study was to evaluate the effectiveness and safety of DAA in KTx and HD patients in real-world settings. Methods Sustained virologic response (SVR) and treatment safety were analyzed in KTx and HD patients from the EpiTer-2 database, which included HCV-infected subjects treated with DAA between 2015 and 2019. Additionally, for KTx patients, changes in creatinine concentration, estimated glomerular filtration rate (eGFR), proteinuria within a year after treatment, and changes in the need for calcineurin inhibitors were assessed. Results Among 10,152 patients from the EpiTer-2 database 148 were selected, 85 after KTx and 63 undergoing HD. The most common genotype, 1b HCV, was found in 73% and 86% of patients, respectively. Cirrhosis was noted in 10% and 19%, respectively. The most common DAA regimen after KTx was sofosbuvir/ledipasvir (54%), whereas in HD patients it was ombitasvir/paritaprevir/ritonavir +/- dasabuvir (56%). All patients with available follow-up results achieved SVR. No deaths, kidney loss or acute rejection episodes were noted. The most common adverse effects in both groups were anemia and weakness. One year after treatment, creatinine concentration, eGFR and proteinuria remained stable in the majority of patients. Conclusion DAA treatment of HCV infection demonstrated high effectiveness and safety in hemodialyzed patients and patients who had undergone KTx in this real-world study.

Abstract
Od zakończenia zimnej wojny dzielenie świata na Globalną Północ i Globalne Południe stało się ogólnie przyjętym sposobem myślenia o globalnej różnicy. Ta opozycja binarna wymazuje jednak istnienie tego, co nazywam Globalnym Wschodem – krajów i społeczeństw, które zajmują pozycję pośrednią, pomiędzy Północą a Południem. Niniejszy artykuł problematyzuje geopolitykę wiedzy powstałą wskutek wykluczenia Globalnego Wschodu, nie tylko z Globalnej Północy i Południa, ale z koncepcji globalności w ogóle. Argumentuje, że w celu odzyskania Globalnego Wschodu dla nauki musimy wykorzystać stanowisko strategicznego esencjalizmu. Analizuje w tym kontekście globalne powiązania kryjące się za szklankami z fazowanego szkła z IKEI, by pokazać konieczność pomyślenia Globalnego Wschodu w sercu globalnych stosunków, a nie poza nimi. Myślenie o Globalnym Wschodzie jako przestrzeni liminalnej problematyzuje pojęcia Północy i Południa na rzecz bardziej inkluzywnego, ale również mniej dookreślonego myślenia teoretycznego.

Abstract
Background Tocilizumab, an inhibitor of the interleukin-6 receptor, may decrease the inflammatory response and control the symptoms of severe coronavirus disease 2019 (COVID-19), but the evidence is scarce. Methods This retrospective study included patients with severe COVID-19 requiring oxygen therapy who received tocilizumab in seven centers across Poland. We assessed on-treatment changes in clinical status and inflammatory markers. Results Twenty-eight patients were included (19 male), with a mean age of 61.7 ± 12.4 years. The mean time from symptom onset to the first tocilizumab dose was 10.5 ± 5.7 days. Clinical status improved within 24 hours in 11 (39%) patients, within one week in 23 (82%) patients, and within two weeks in 25 (89%); one (4%) patient showed no change and two (7%) patients died. Sixteen patients (57%) no longer needed oxygen therapy within a week (p < 0.001). The serum concentrations of C-reactive protein, procalcitonin, and fibrinogen decreased significantly (p ≤ 0.001). Lung changes improved in 21 (84%) patients within two weeks of treatment; 19 had minimal or no changes upon final examination. Conclusions Tocilizumab can control the symptoms of severe COVID-19 by reducing the inflammatory response and rapidly improves the clinical status in most patients.

Abstract
BACKGROUND AND AIM Grazoprevir/elbasvir (GZR/EBR) was approved for the treatment of chronic hepatitis C virus (HCV) genotype 1 and 4 infected patients with or without compensated liver cirrhosis. The aim of this study was to assess GZR/EBR regimen in the real-world experience, particularly in previously "difficult-to-treat" patients with chronic kidney diseases, human immunodeficiency virus-coinfected, cirrhotics, and treatment-experienced. METHODS The analysis included patients treated with GZR/EBR selected from 10 152 individuals from the EpiTer-2 database, large national real-world study evaluating antiviral treatment in 22 Polish hepatology centers between 2015 and 2018. Data were completed retrospectively and submitted online. RESULTS A total of 1615 patients who started GZR/EBR therapy in 2017 and 2018 with a female predominance (54%) and median age of 54 years were analyzed. The majority were infected with GT1b (89%) and treatment naïve (81%). Liver cirrhosis was diagnosed in 19%, and 70% of patients had comorbidities, of which chronic renal disease was present in 7% and HIV-coinfection in 4%. Overall, a sustained virologic response (SVR) was achieved by 95% according to intent-to-treat (ITT) and 98% after exclusion of lost to follow up (modified ITT). No differences were found in cure rate between all included patients and subpopulations previously considered as difficult-to-treat. Majority of patients completed the treatment course as scheduled, adverse events were mostly mild and did not lead to therapy discontinuation. CONCLUSIONS GZR/EBR treatment carried-out in patients infected with HCV genotype 1 and 4 demonstrated good tolerability and an excellent SVR rate with no effectiveness reduction in so called difficult-to-treat populations.

Abstract
OBJECTIVES The aim of the study was to analyze the prevalence and clinical characteristics of HCV/HBV coinfection and to evaluate the rate of HBV-reactivation during anti-HCV therapy in a large real-world study. METHODS Analyzed population consisted of 10,152 chronic hepatitis C patients treated with DAA between 2015 and 2019 in a nationwide study. Prior to the DAA all subjects had HBsAg and 60% anti-HBc testing. RESULTS 111 of 10,152 patients (1.1%) had detectable HBsAg and 1239 of 6139 (20.2%) anti-HBcAb. The prevalence of occult hepatitis B was 0.48%. HCV/HBV patients were younger with a higher proportion of males, HIV-coinfected, and advanced fibrosis. They were less often diagnosed with diabetes but more often with chronic kidney disease. In HBsAg(+) subjects with baseline HBV-DNA available 6/102 (5.9%) HBV-reactivations during or after DAA therapy were observed, and in two (1.9%) significant hepatic flares were noted. In HBsAg(-)/anti-HBc(+) group 2 (0.16%) reactivations were observed only in patients undergoing immunosuppressive therapy. DISCUSSION Data from a large European cohort suggest a relatively low risk of HBV-reactivation during DAA-therapy for HCV infection in HBsAg(+) patients. In HBsAg(-)/anti-HBc(+) HBV-reactivation seems to be limited to subjects with immunodeficiency. Importantly, previous exposure to HBV and occult hepatitis B is present in a significant proportion of HCV-infected.

Abstract
The hepatitis C virus (HCV) is known as a main etiological cause of chronic hepatitis. HCV infection disturbs cholesterol metabolism of the host, which is frequently observed in patients suffering from chronic hepatitis C (CHC). The course of viral infections remains under strict control of microRNA (miRNA). In the case of HCV, miR-122 exerts a positive effect on HCV replication in vitro. The purpose of this study was to investigate the impact of peginterferon alpha (pegIFN-α) and ribavirin treatments on the expression of miR-122 and the cholesterol level in the peripheral blood mononuclear cells (PBMCs) of CHC patients. We report here that the level of miR-122 expression in the PBMCs decreased after the antiviral treatment in comparison to the pretreated state. Simultaneously, the level of cholesterol in the PBMCs of CHC patients was higher six months following the treatment than it was pretreatment. Consequently, it seems that the decrease of miR-122 expression in the PBMCs of CHC patients is one of the antiviral effects connected with the pegIFN-alpha/ribavirin treatments.

Abstract
PURPOSE Since 2017 treatment-naïve patients infected with genotype 1b of hepatitis C virus and minimal or moderate fibrosis can be treated with Ombitasvir/Paritaprevir/ritonavir + Dasabuvir (OPrD) for 8 weeks according to updated Summary of Product Characteristics. The aim of our study was to assess the comparative efficacy of 8 and 12-weeks therapy with OPrD in large cohort of patients eligible for 8 weeks regimen treated in real-world setting. MATERIALS AND METHODS We analysed data of 3067 HCV genotype 1b infected patients treated with OPrD between 2015 and 2017. Final analysis included patients with none, minimal or moderate fibrosis (F0-F2). RESULTS A total of 771 patients were enrolled in the study, including 197 (26%) treated for 8-weeks and 574 patients fulfilling criteria for 8-weeks but assigned to 12-weeks regimen. Majority of patients had no or minimal fibrosis (F0-F1). Longer treatment duration was more often administered in patients with moderate fibrosis, comorbidities, concomitant medications. SVR was achieved in 186 (94%) patients treated for 8 weeks and 558 (97%) for 12 weeks (p = 0.07). After exclusion of lost to follow-up patients, sustained virological response (SVR) rate reached 95% and 99%, respectively (p = 0.01). We were not able to identify factors associated with non-response. CONCLUSIONS This real-word experience study confirmed similar, high effectiveness of 8 and 12-weeks regimens of OPrD in genotype 1b HCV infected patients with non-advanced fibrosis. Despite of reduced SVR rate after 8-weeks regimen, there is no need to extend therapy to 12-weeks in vast majority of such patients and no need to add ribavirin.

Abstract
Background and Aims: Hepatocellular carcinoma (HCC) is the most common primary liver cancer. The etiology of this disease is known in 90% of the patients, and it is viral in most of the cases. According to recent predictions, nearly half of the world population will be suffering from obesity by 2030. Consequently, non-alcoholic fatty liver disease (NAFLD) may play a growing role in HCC epidemiology. In this review, we sought to explore the relationship between liver steatosis and HCC.Methods: A narrative review was conducted using the PubMed MeSH search. The eligible papers were identified using a standard PubMed search with relevant key terms and various synonyms.Results: According to the results, patients with NAFLD-HCC tended to be older than those with hepatitis C virus (HCV)-HCC, and they were more often obese and had concomitant diseases, such as diabetes. On the other hand, the synthetic liver function was better preserved in NAFLD-HCC patients, who also obtained lower scores on the Model for End-stage Liver Disease (MELD) and Child-Turcotte-Pugh (CTP). However, it has to be noted that HCC in patients with non-alcoholic steatohepatitis (NASH) may develop without underlying cirrhosis. Although NASH-HCC is usually smaller and well-differentiated compared to HCV-HCC, the prognosis is similar in both groups. Efficient HCC screening in NASH cirrhosis poses a challenge because it is difficult to perform ultrasound examination in obese patients and alfa-fetoprotein level is no longer considered reliable.Conclusions: The constantly increasing prevalence of NAFLD in the general population can contribute to a growing role of NAFLD/NASH in HCC epidemiology. Moreover, some particular challenges specific for patients with liver steatosis may impede proper HCC diagnosis, treatment and follow-up.

Week 48 Resistance Analyses of the Once-Daily, Single-Tablet Regimen Darunavir/Cobicistat/Emtricitabine/Tenofovir Alafenamide (D/C/F/TAF) in Adults Living with HIV-1 from the Phase III Randomized AMBER and EMERALD Trials. AIDS Res Hum Retroviruses 2020; 36:48-57.

Abstract
Darunavir/cobicistat/emtricitabine/tenofovir alafenamide (D/C/F/TAF) 800/150/200/10 mg is being investigated in two Phase III trials, AMBER (NCT02431247; treatment-naive adults) and EMERALD (NCT02269917; treatment-experienced, virologically suppressed adults). Week 48 AMBER and EMERALD resistance analyses are presented. Postbaseline samples for genotyping/phenotyping were analyzed from protocol-defined virologic failures (PDVFs) with viral load (VL) ≥400 copies/mL at failure/later time points. Post hoc analyses were deep sequencing in AMBER, and HIV-1 proviral DNA from baseline samples (VL <50 copies/mL) in EMERALD. Through week 48 across both studies, no darunavir, primary PI, or tenofovir resistance-associated mutations (RAMs) were observed in HIV-1 viruses of 1,125 participants receiving D/C/F/TAF or 629 receiving boosted darunavir plus emtricitabine/tenofovir-disoproxil-fumarate. In AMBER, the nucleos(t)ide analog reverse transcriptase inhibitor (N(t)RTI) RAM M184I/V was identified in HIV-1 of one participant during D/C/F/TAF treatment. M184V was detected pretreatment as a minority variant (9%). In EMERALD, in participants with prior VF and genoarchive data (N = 140; 98 D/C/F/TAF and 42 control), 4% had viruses with darunavir RAMs, 38% with emtricitabine RAMs, mainly at position 184 (41% not fully susceptible to emtricitabine), 4% with tenofovir RAMs, and 21% ≥ 3 thymidine analog-associated mutations (24% not fully susceptible to tenofovir) detected at screening. All achieved VL <50 copies/mL at week 48 or prior discontinuation. D/C/F/TAF has a high genetic barrier to resistance; no darunavir, primary PI, or tenofovir RAMs were observed through 48 weeks in AMBER and EMERALD. Only one postbaseline M184I/V RAM was observed in HIV-1 of an AMBER participant. In EMERALD, baseline archived RAMs to darunavir, emtricitabine, and tenofovir in participants with prior VF did not preclude virologic response.

Vertigo and Severe Balance Instability as Symptoms of Lyme Disease-Literature Review and Case Report. Front Neurol 2019; 10:1172. [PMID: 31798513 PMCID: PMC6861545 DOI: 10.3389/fneur.2019.01172] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2019] [Accepted: 10/21/2019] [Indexed: 11/17/2022] Open
Abstract
Lyme disease is caused by a tick-borne bacterium Borrelia sp. This zoonotic infection is common in the Northern Hemisphere, e.g., Europe. Clinical presentation may involve multisystem symptoms and depends on the stage of the disease. The involvement of nervous system in Lyme disease is commonly referred to as neuroborreliosis. Neuroborreliosis may involve meningitis, mononeuritis multiplex, or cranial neuritis including the inflammation of vestibulocochlear nerve. In the late or chronic stage of Lyme disease, vestibular involvement may be the sole presentation, although such cases are rare. Our study was designed to present our own case and review the available literature reporting cases of neuroborreliosis with vertigo/dizziness and severe balance instability as a main disease symptom. The studies were obtained by searching the following databases: PubMed, Medline, and Embase. We included case reports of Lyme disease presenting with vertigo or gait disorders as the main symptom, written in the English language. Initially, 60 papers were identified. After analyzing the abstracts, seven manuscripts focusing on 13 clinical cases were included in this review. We conclude that the patients with neuroborreliosis sometimes present vertigo/dizziness, but rarely gait ataxia as a sole symptom. These complaints are usually accompanied by a hearing loss. Antibiotic treatment is usually effective. Balance instability in the patients with neuroborreliosis may persist but it responds well to vestibular rehabilitation.
