RESUMEN
To date, the effectiveness of direct-acting antivirals (DAAs) discontinued before 4 weeks has not been analysed in routine clinical practice. The study aimed to determine whether such a short therapy will enable achieving a sustained virological response under real-world experience. The study population of 97 patients who discontinued DAA therapy and had data enabling analysis of patient and disease characteristics, and assessment of treatment effectiveness was selected from 16,815 patients registered in the EpiTer-2 database. The most common reason for discontinuation was hepatic decompensation (20.6%) or the patient's personal decision (18.6%). Patients who discontinued treatment were significantly older, more frequently therapy-experienced, more likely to have cirrhosis, a history of decompensation and a Child-Pugh B or C classification than those who completed treatment. SVR was achieved by 93.5% of patients who discontinued treatment after 4 weeks, 60.9% if discontinued at 3 or 4 week and 33.3% at Week 1 or 2. Patients receiving pangenotypic but not genotype-specific treatment who discontinued after 4 weeks were as likely to achieve SVR as those who completed therapy. Patients who responded to treatment that lasted no longer than 2 weeks had a low baseline viral load (<400,000 IU/mL). Despite discontinuation of therapy after Week 4, the chances of SVR are high. Very early discontinuation does not preclude therapeutic success, especially in patients with low baseline viral load.
RESUMEN
BACKGROUND: Hepatitis C virus (HCV) infection affects 50 million people worldwide with around 242,000 deaths annually, mainly due to complications such as cirrhosis and hepatocellular carcinoma (HCC). Portal hypertension (PH) caused by cirrhosis leads to severe consequences, including esophageal varices (EV). This study aimed to evaluate the effectiveness and safety of direct-acting antiviral (DAA) treatment in patients with and without EV. METHODS: This retrospective analysis involved consecutive HCV-infected adults undergoing DAA therapy at 22 Polish hepatology centers from July 1, 2015, to December 31, 2022. Patients with cirrhosis were categorized based on the presence of EV diagnosed by gastroscopy. Treatment effectiveness was measured by sustained virologic response (SVR), with safety outcomes monitored for 12 weeks post-treatment. RESULTS: A population of 3393 HCV-infected patients with cirrhosis was divided into groups with (A, n = 976) and without (B, n = 2417) EV. Group A showed a significantly higher prevalence of comorbidities and concomitant medications. Genotype (GT)1b infections predominated in both groups, and GT3 infections were more common in the EV group. Group A exhibited more severe liver disease, and higher rates of decompensation, HCC, and HBV co-infection. SVR was significantly higher in group B (91.5% vs. 96.3%, p < 0.0001). Male gender, GT3, EV presence, and Child-Pugh grade B were identified as independent negative SVR predictors. Group A had a worse safety profile, with notably higher adverse event incidence and mortality. CONCLUSIONS: DAA therapies are highly effective and well tolerated in patients with cirrhosis, but EV presence predicts poorer virologic responses.
RESUMEN
Objectives: This study analyzed trends in HIV/AIDS in Poland over the time period of 2009-2021 and the potential impact of COVID-19 and the migration of war refugees from Ukraine. Methods: Long-term trends were assessed by joinpoint regression using data from Polish HIV/AIDS registries. The HIV/AIDS burden was also compared before and during the pandemic and refugee migration. Results: In 2009-2021, the upward tendency in the rate of new HIV infections until 2017 and decrease after 2017 was accompanied by a downward trend in new HIV/AIDS diagnoses and mortality. From the pandemic's beginning until March 2022, rates of new HIV/AIDS diagnoses dramatically decreased to later increase to pre-pandemic levels, which partially coincided with the wave of migration of refugees from Ukraine. Conclusions: Long-term analysis of HIV/AIDS in Poland showed a downward trend in new HIV/AIDS diagnoses and related mortality in 2009-2021. While the pandemic has reduced the number of detected HIV/AIDS cases, a subsequent increase in new HIV diagnoses in 2022 may be related to lifting the COVID-19 restrictions and war refugees' migration. These observations have implications for the WHO European Region, seeking to end AIDS as a public health problem by 2030.
RESUMEN
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic is associated with increases in morbidity and mortality worldwide. The mechanisms of how SARS-CoV-2 may cause cardiovascular (CV) complications are under investigation. The aim of the study was to assess the impact of the COVID-19 pandemic on CV risk. METHODS: These are single-centre Bialystok PLUS (Poland) population-based and caseâcontrol studies. The survey was conducted between 2018 and 2022 on a sample of residents (n = 1507) of a large city in central Europe and patients 6-9 months post-COVID-19 infection (n = 126). The Systematic Coronary Risk Estimation 2 (SCORE2), the Systematic Coronary Risk Estimation 2-Older Persons (SCORE2-OP), the Cardiovascular Disease Framingham Heart Study and the LIFEtime-perspective model for individualizing CardioVascular Disease prevention strategies in apparently healthy people (LIFE-CVD) were used. Subsequently, the study populations were divided into CV risk classes according to the 2021 ESC Guidelines on cardiovascular disease prevention in clinical practice. RESULTS: The study population consisted of 4 groups: a general population examined before (I, n = 691) and during the COVID-19 pandemic (II, n = 816); a group of 126 patients post-COVID-19 infection (III); and a control group matched subjects chosen from the pre-COVID-19 pandemic (IV). Group II was characterized by lower blood pressure, low-density lipoprotein cholesterol (LDL-c) and high-density lipoprotein cholesterol (HDL-c) values than group I. Group III differed from the control group in terms of lower LDL-c level. There was no effect on CV risk in the general population, but in the population post-COVID-19 infection, CV risk was lower using FS-lipids, FS-BMI and LIFE-CVD 10-year risk scores compared to the prepandemic population. In all subgroups analysed, no statistically significant difference was found in the frequency of CV risk classes. CONCLUSIONS: The COVID-19 pandemic did not increase the CV risk calculated for primary prevention. Instead, it prompted people to pay attention to their health status, as evidenced by better control of some CV risk factors. As the COVID-19 pandemic has drawn people's attention to health, it is worth exploiting this opportunity to improve public health knowledge through the design of wide-ranging information campaigns.

BACKGROUND AND AIMS: Chronic liver diseases belong to the most common diseases worldwide and are associated with increased morbidity and mortality. Although more than one in three adults are estimated to have metabolic dysfunction-associated steatotic liver disease (MASLD), awareness of this condition is low amongst the general public, health care professionals and policy makers. However, meaningful knowledge transfer is essential for raising awareness and improving prevention and treatment. This study set out to investigate the use of the major internet search engine to understand how knowledge transfer has evolved by analyzing liver-related searches trends. METHODS: We investigated Google search trends by measuring the number of hits relating to liver diseases between 2004 and 2021 in seven languages and European countries but also worldwide. All analyses were performed in R using the R Google trends package gtrendsR. RESULTS: We found that interest in MASLD [formerly non-alcoholic fatty liver disease (NAFLD)] has generally increased over time, but that interest in metabolic associated steatohepatitis (MASH) - the most severe form of MASLD - has decreased. Interest in viral hepatitis C has decreased, whereas the number of queries regarding viral hepatitis B have been stable but dominated by interest in vaccination for it. Recent medical developments (in viral hepatitis) did not lead to a noticeable change in overall search behavior. Users preferred searching using their native language and less complex medical terms and acronyms (e.g., fatty liver instead of NAFLD). CONCLUSIONS: In the last two decades, Google search trends have followed the general development in the field of hepatology. Searches were dominated by non-experts and are not being rapidly influenced by novel scientific developments. Also, users preferred search terms in their native languages rather than English and tended to avoid complex medical search terms. Awareness and communication strategies around MASLD should consider these preferences when addressing the general public.

INTRODUCTION: With the introduction of highly effective and safe therapies with next-generation direct-acting antivirals (DAAs), that act without interferon, hepatitis C virus (HCV) infection remains the only treatable chronic infectious disease. AREAS COVERED: The review aims to provide an overview of the therapy revolution with a description of specific DAAs, their mechanisms of action, a summary of the safety and efficacy of specific regimens, and a discussion of populations requiring special therapeutic approaches. EXPERT OPINION: DAAs are highly effective, safe, and easy to use. However, challenges such as access to health services and loss of patients from the cascade of care, especially in groups disproportionately affected by HCV infection, such as substance abusers, make it difficult to achieve the WHO's goal of HCV elimination. The proposed strategy to combat these difficulties involves a one-step approach to diagnosing and treating the infection, the availability of long-lasting forms of medication, and the development of an effective vaccine. The aforementioned opportunities are all the more important as the world is facing an opioid epidemic that is translating into an increase in HCV prevalence. This phenomenon is of greatest concern in women of childbearing age and in those already pregnant due to treatment limitations.
Hepatitis C virus (HCV) is an insidious pathogen. Most people infected with HCV will develop chronic infections that may not give any symptoms for years or decades but eventually lead to liver disease and liver cancer. It is essential to diagnose infected individuals as soon as possible and start the treatment to increase the elimination of the virus from the organism and prevent harmful long-term effects.Fortunately, these goals are possible nowadays, and this is due to a remarkable example of translational research at work. The discovery of the virus in 1989 (for which Harvey J. Alter, Michael Houghton, and Charles M. Rice received the Nobel Prize in 2020) was followed by the rapid development of diagnostic tests and later by the introduction of the first interferon therapies, which had numerous shortcomings. The revolution started in 2011 when the first oral drugs that act directly on HCV (direct-acting antivirals, DAAs) were registered. Another giant leap for HCV treatment was made in 2018 when the combinations of DAAs that act on different HCV genotypes were introduced.In this paper, we review in detail the DAAs used to treat HCV infection and explain different combinations in which they can be used while showing their favorable safety profile, short-term and convenient treatment regimen, and impressive effectiveness in clearing HCV infection. Although we believe eliminating HCV is eventually reachable, we also argue that there is room for improvement. HCV testing and DAAs availability must improve in selected groups, including people without health insurance, prisoners, and drug addicts. There are still people living with chronic HCV infection without knowing it. Their identification and start of effective treatment is equal to savings in future medical care related to liver disease and cancer, not to mention benefits from the individual health perspective. In addition, and in line with a popular phrase that prevention is better than cure, it is reasonable to pursue the development of the HCV vaccine, which is currently unavailable. The last word on managing the health burden caused by this pathogen is yet to be said.

Long COVID (LC) is characterized by persistent symptoms following SARS-CoV-2 infection, with various mechanisms offered to explain its pathogenesis. This study explored whether adaptive humoral anti-SARS-CoV-2 responses differ in LC. Unvaccinated COVID-19 convalescents (n = 200) were enrolled, with 21.5% (n = 43) presenting LC three months post-infection. LC diagnosis was based on persistent symptom(s) and alterations in biochemical/clinical markers; three phenotypes were distinguished: cardiological, pulmonary, and psychiatric LC. All three phenotypes were characterized by significantly decreased seroprevalence of IgG antibodies against nucleocapsid (anti-NP). LC was associated with decreased odds of testing positive for anti-NP (OR = 0.35, 95%CI: 0.16-0.78, p = 0.001). Seropositive LC patients had lower anti-S1 and anti-S2 levels than individuals without LC, and those with pulmonary and psychological phenotypes also revealed decreased anti-RBD concentrations. The results indicate that LC can be characterized by diminished humoral response to SARS-CoV-2. The potential implication of this phenomenon in post-acute viral sequelae is discussed.

BACKGROUND COVID-19 manifests with varying degrees of severity across different age groups; adults typically experience more severe symptoms than children. Matrix metalloproteinases (MMPs), known for their role in tissue remodeling and immune responses, may contribute to the pathophysiological disparities observed between these groups. We sought to delineate differences in serum MMP profiles between adult and pediatric COVID-19 patients, assess the influence of anti-inflammatory treatment on MMP levels, and examine potential implications for long-term consequences. MATERIAL AND METHODS Serum samples from adult and pediatric COVID-19 patients, alongside controls, were analyzed for MMP-1, MMP-2, MMP-3, MMP-7, MMP-8, MMP-9, MMP-10, MMP-12, MMP-13, EMMPRIN, TNF-alpha, TIMP-1, TIMP-2, TIMP-3, and TIMP-4. A subset of adult patients received treatment with glucocorticoids, tocilizumab, and convalescent plasma, and MMP levels were compared with those of untreated patients. RESULTS Elevated levels of MMP-1, MMP-7, TIMP-1, and TIMP-2 were observed in adult and pediatric patients. Adult patients displayed higher concentrations of MMP-3, MMP-8, MMP-9, TNF-alpha, and TIMP-4 than children. Post-treatment reduction in MMP-1, MMP-8, MMP-9 levels was observed, with median decreases from 21% to 70%. MMP-3 and MMP-7 remained largely unchanged, and MMP-2 concentrations increased after treatment. Notably, anti-inflammatory treatment correlated with reduced post-treatment MMP levels, suggesting potential therapeutic benefit. CONCLUSIONS Distinctive inflammatory responses in COVID-19 were evident between adults and children. While certain MMPs exhibited post-treatment reduction, the persistence of elevated levels raises concerns about potential long-term consequences, including lung fibrosis. Our findings emphasize the need for personalized treatment strategies and further investigation into the dynamics of MMP regulation in COVID-19.

Understanding how the infectious disease burden was affected throughout the COVID-19 pandemic is pivotal to identifying potential hot spots and guiding future mitigation measures. Therefore, our study aimed to analyze the changes in the rate of new cases of Poland's most frequent infectious diseases during the entire COVID-19 pandemic and after the influx of war refugees from Ukraine. We performed a registry-based population-wide study in Poland to analyze the changes in the rate of 24 infectious disease cases from 2020 to 2023 and compared them to the prepandemic period (2016-2019). Data were collected from publicly archived datasets of the Epimeld database published by national epidemiological authority institutions. The rate of most of the studied diseases (66.6%) revealed significantly negative correlations with the rate of SARS-CoV-2 infections. For the majority of infectious diseases, it substantially decreased in 2020 (in case of 83%) and 2021 (63%), following which it mostly rebounded to the prepandemic levels and, in some cases, exceeded them in 2023 when the exceptionally high annual rates of new cases of scarlet fever, Streptococcus pneumoniae infections, HIV infections, syphilis, gonococcal infections, and tick-borne encephalitis were noted. The rate of Clostridioides difficile enterocolitis was two-fold higher than before the pandemic from 2021 onward. The rate of Legionnaires' disease in 2023 also exceeded the prepandemic threshold, although this was due to a local outbreak unrelated to lifted COVID-19 pandemic restrictions or migration of war refugees. The influx of war migrants from Ukraine could impact the epidemiology of sexually transmitted diseases. The present analysis indicates that continued efforts are needed to prevent COVID-19 from overwhelming healthcare systems again and decreasing the control over the burden of other infectious diseases. It also identifies the potential tipping points that require additional mitigation measures, which are also discussed in the paper, to avoid escalation in the future.

BACKGROUND: The aim of this study was to evaluate the real-life efficacy of pangenotypic antivirals in HIV-HCV-positive patients. RESEARCH DESIGN AND METHODS: The analysis included 5650 subjects who were treated with pangenotypic anti-HCV drugs: 5142 were HCV-positive and 508 were HIV-HCV-positive. RESULTS: Patients with HCV-monoinfection were older (p < 0.0001), however patients with HCV-monoinfection had a higher proportion of advanced fibrosis F4 (p < 0.0001). There were no differences between the study groups in the rate of SVR12 in ITT-analysis (87,6% versus 93,9% in coinfection and monoinfection group, respectively; p > 0.05). However, there was a difference between study groups in PP-analysis, HIV/HCV and HCV, respectively 95.9% vs 97.9%, p = 0.0323. Additionally, there were a higher rate of patients who did not apply for follow-up (SVR12) in coinfected patients (7,9% vs 3,6% respectively p = 0.0001). In multivariante analysis, factors associated with worse response to the pangenotypic anti-HCV therapy included male sex, HCV genotype 3, stage of fibrosis and decompensation of liver function and HIV coinfection. CONCLUSIONS: The real-life results of pangenotypic anti-HCV treatment are veryeffective in the group of HIV-HCV-coinfected patients. However, the finaleffectiveness is slightly lower than that obtained in HCV monoinfectedpatients.
RESUMEN
The COVID-19 pandemic has reinforced an interest in the relationship between air pollution and respiratory viral infections, indicating that their burden can be increased under poor air quality. This paper reviews the pathways through which air pollutants can enhance susceptibility to such infections and aggravate their clinical course and outcome. It also summarizes the research exploring the links between various viral infections and exposure to solid and gaseous pollution in Poland, a region characterized by poor air quality, especially during a heating season. The majority of studies focused on concentrations of particulate matter (PM; 86.7%); the other pollutants, i.e., BaP, benzene, CO, NOx, O3, and SO2, were studied less often and sometimes only in the context of a particular infection type. Most research concerned COVID-19, showing that elevated levels of PM and NO2 correlated with higher morbidity and mortality, while increased PM2.5 and benzo[a]pyrene levels were related to worse clinical course and outcome in hospitalized, regardless of age and dominant SARS-CoV-2 variant. PM10 and PM2.5 levels were also associated with the incidence of influenza-like illness and, along with NO2 concentrations, with a higher rate of children's hospitalizations due to lower respiratory tract RSV infections. Higher levels of air pollutants also increased hospitalization due to bronchitis (PM, NOx, and O3) and emergency department admission due to viral croup (PM10, PM2.5, NOx, CO, and benzene). Although the conducted studies imply only correlations and have other limitations, as discussed in the present paper, it appears that improving air quality through reducing combustion processes in energy production in Poland should be perceived as a part of multilayered protection measures against respiratory viral infections, decreasing the healthcare costs of COVID-19, lower tract RSV infections, influenza, and other respiratory viral diseases prevalent between autumn and early spring, in addition to other health and climate benefits.

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.

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.

Hepatitis A virus (HAV) is the most common cause of acute viral hepatitis, which is preventable by vaccination. This study analyzed trends of HAV infections in Poland according to socio-demographic features in the years 2009-2022 and assessed the potential impact of the COVID-19 pandemic (2020-2023) and the migration of war refugees from Ukraine (since February 2022). In 2009-2022, 7115 new cases of HAV infection were diagnosed in Poland, especially among men (66.4%) and in urban areas (77.4%). Infections among men were most common at the age of 25-34 (median rate 0.43 per 105) and in women aged 15-24 (median rate 0.39 per 105). Analysis of the 14-year frequency of HAV infections exhibited three trends, regardless of gender, age, and residence. The infections revealed a downward trend in 2009-2014, increased significantly in 2014-2018, and decreased again after 2018. A particularly rapid increase in HAV infections occurred between March 2017 and February 2018 (median rate 0.79 per 105). The high level of new infections persisted until the beginning of the COVID-19 pandemic, at which point it dropped significantly but did not reach the level recorded before March 2017. During the Omicron SARS-CoV-2 dominance period, the median rate of HAV infections was 0.053 per 105, with a four-fold increase being observed from February 2022 (when the migration of war refugees from Ukraine began) to August 2022. The presented results can serve as a reference point for further observations in Central Europe. The HAV epidemiological situation is unlikely to escalate in Poland but requires further monitoring.

This review aims to explore the role of professional diagnostic rapid testing of acute respiratory infections (ARIs), especially COVID-19 and influenza, ensuring proper disease management and treatment in Europe, and particularly in Czech Republic, Poland, and Romania. The paper was constructed based on a review of scientific evidence and national and international policies and recommendations, as well as a process of validation by four experts. The development of new testing technologies, treatment options, and increased awareness of the negative multidimensional impact of ARI profiles transformed differential diagnosis into a tangible and desirable reality. This review covers the following topics: (1) the multidimensional impact of ARIs, (2) ARI rapid diagnostic testing platforms and their value, (3) the policy landscape, (4) challenges and barriers to implementation, and (5) a set of recommendations illustrating a path forward. The findings indicate that rapid diagnostic testing, including at the point of care (POC), can have a positive impact on case management, antimicrobial and antibiotic stewardship, epidemiological surveillance, and decision making. Integrating this strategy will require the commitment of governments and the international and academic communities, especially as we identified room for improvement in the access and expansion of POC rapid testing in the focus countries and the inclusion of rapid testing in relevant policies.
RESUMEN
INTRODUCTION: Pangenotypic therapies for infections with hepatitis C virus (HCV), although universal and highly effective, entail a risk of treatment failure. OBJECTIVES: Our study aimed to identify the population of HCVinfected patients most difficult to cure with the sofosbuvir / velpatasvir (SOF/VEL) regimen. PATIENTS AND METHODS: The effectiveness of the SOF/VEL regimen with a possible addition of ribavirin (RBV) was evaluated in populations known to be less responsive to treatment, and then in a population characterized by the combination of all factors impairing effectiveness, comprising patients treated with this regimen in the EpiTer2 multicenter retrospective study. RESULTS: A total of 2267 patients were treated with SOF/VEL±RBV. Of those, 2078 (96.4%) achieved sustained virologic response. The cure rate was 93.5% among 646 patients infected with genotype (GT) 3, 92.3% among 635 patients with cirrhosis, 95.5% in a population of 1233 men, and 94.1% among 421 patients with body mass index (BMI) above 30. An analysis in a group of 43 men with cirrhosis and obesity infected with GT3 showed the effectiveness of pangenotypic therapy at only 79.1%, falling to 66.7% in individuals with previous treatment failure. CONCLUSIONS: In a large population of SOF/VELtreated HCVinfected patients, we showed relatively low effectiveness of the regimen in treatmentexperienced men with cirrhosis and obesity, infected with GT3. Triple therapy should be considered when initiating the treatment of HCV infections in this group, which, however, needs to be confirmed in further studies. Previous studies were conducted in less demanding populations, because they did not take into account sex and BMI, which significantly affect the treatment effectiveness.

INTRODUCTION: Hepatitis B virus (HBV) and hepatitis C virus (HCV) share a similar transmission route, which increases coinfection odds and worsens clinical outcomes. OBJECTIVES: Our aim was to investigate coinfected patients undergoing HCV treatment with direct-acting antivirals (DAAs) to understand their characteristics, risk of HBV reactivation, and effectiveness of the therapy. PATIENTS AND METHODS: Our study comprehensively analyzed 1118 patients with chronic HCV infection, divided into 3 subgroups based on their HBV status. RESULTS: We documented that 0.7% of the analyzed population was positive for hepatitis B virus surface antigen (HBsAg), while 14.3% had evidence of a past HBV infection. The patients without HBV coinfection were less burdened with comorbidities, and were mostly treatment-naive, while the individuals suffering from coinfection were younger and more likely to have a history of a previous therapy. Infection with HCV genotype 3 was more common among the HBsAg-positive patients than in the other studied groups. Response to DAA therapy was comparable between the groups, and most patients completed the course of treatment as planned. Only 3 cases of HBV reactivation were observed, all of which achieved sustained virologic response after DAA therapy. Two were women on immunosuppressants with antihepatitis B core positive antibodies, and the third patient was an HBsAgpositive man. These patients remained in long-term follow-up. CONCLUSIONS: Neither the presence of HBV markers nor HBV reactivation during DAA treatment reduced effectiveness of the therapy. Our findings are important for future recommendations and guidelines on managing HBV/HCV coinfection.

The hepatitis B virus (HBV) continues to cause substantial health and economic burdens, and its target of elimination may not be reached in 2030 without further efforts in diagnostics, non-pharmaceutical prevention measures, vaccination, and treatment. Current therapeutic options in chronic HBV, based on interferons and/or nucleos(t)ide analogs, suppress the virus replication but do not eliminate the pathogen and suffer from several constraints. This paper reviews the progress on biotechnological approaches in functional and definitive HBV treatments, including gene-editing tools, i.e., zinc-finger proteins, transcription activator-like effector nucleases, and CRISPR/Cas9, as well as therapeutics based on RNA interference. The advantages and challenges of these approaches are also discussed. Although the safety and efficacy of gene-editing tools in HBV therapies are yet to be demonstrated, they show promise for the revitalization of a much-needed advance in the field and offer viral eradication. Particular hopes are related to CRISPR/Cas9; however, therapeutics employing this system are yet to enter the clinical testing phases. In contrast, a number of candidates based on RNA interference, intending to confer a functional cure, have already been introduced to human studies. However, larger and longer trials are required to assess their efficacy and safety. Considering that prevention is always superior to treatment, it is essential to pursue global efforts in HBV vaccination.

This study analyzed data for 1098 children: 575 diagnosed with COVID-19 between January and June 2022 (early Omicron) and 523 hospitalized from July 2022 to April 2023 (late Omicron). New Omicron subvariants lead to similar recovery rates without deaths and acute respiratory distress syndrome in children as BA.1 and BA.2, however, they more often cause fever and croup. Children suffering from comorbidities, presenting with pulmonary lesions and older, may be prone to a more severe consequences of COVID-19 in terms of the currently dominating Omicron subvariants.
