After the declaration Global Health Sector Strategy on Viral Hepatitis by the World Health Organization in 2016, the Turkish Government defined a national strategy covering 2018-2023 to reach goals by 2030. Following a participatory decision process and a series of workshops, the strategy was built on eight separate subheadings. Apart from the official Prevention and Control Program, two separate road maps for hepatitis B and C were developed to obtain targets accessible with the cooperation of the Viral Hepatitis Society and the Turkish Association for the Study of the Liver in 2018 and 2020, respectively. Up to 2023, achievements and the current situation of the National Viral Hepatitis Prevention and Control Program and the hepatitis B virus and hepatitis C virus road maps were assessed in detail on June 28th, 2022, by the subject matter experts in Turkey. Besides the officially reported achievement rate (42\%) of the Program in 2021, participants mentioned undesirable effects of the coronavirus disease-2019 pandemic, unregulated migration, low levels of professional and public awareness, and barriers to access to anti-viral treatment. Recommendations focused on increasing the efficiency of screening and surveillance by integrating the viral carrier identity of individuals into the national health information system, simplifying the drug supplement and treatment initiation process and insisting on education to raise awareness.

Background Critically ill COVID-19 patients are prone to bloodstream infections (BSIs). Aim To evaluate the incidence, risk factors, and prognosis of BSIs developing in COVID-19 patients in the intensive care unit (ICU). Methods Patients staying at least 48 h in ICU from 22 March 2020 to 25 May 2021 were included. Demographic, clinical, and laboratory data were analyzed. Results The median age of the sample (n = 470) was 66 years (IQR 56.0-76.0), and 64% were male. The three most common comorbidities were hypertension (49.8%), diabetes mellitus (32.8%), and coronary artery disease (25.7%). Further, 252 BSI episodes developed in 179 patients, and the BSI incidence rate was 50.2 (95% CI 44.3-56.7) per 1000 patient-days. The source of BSI is central venous catheter in 42.5% and lower respiratory tract in 38.9% of the episodes. Acinetobacter baumannii (40%) and carbapenem-resistant Klebsiella pneumoniae (21%) were the most common pathogens. CRP levels were lower in patients receiving tocilizumab. Multivariable analysis revealed that continuous renal replacement therapy, extracorporeal membrane oxygenation, and treatment with a combination of methylprednisolone and tocilizumab were independent risk factors for BSI. The estimated cumulative risk of developing first BSI episode was 50% after 6 days and 100% after 25 days. Of the 179 patients, 149 (83.2%) died, and a statistically significant difference ( p Conclusion BSI is a common complication in COVID-19 patients followed in the ICU, and it can lead to mortality. Failure in infection control measures, intensive immunosuppressive treatments, and invasive interventions are among the main factors leading to BSIs.

Objective: This study was conducted to describe the demographic, clinical, and microbiological characteristics of vertebral osteomyelitis in the last decade, mainly by comparing literature and the previous case series performed in our center. Material and Methods: This is a retrospective, observational, descriptive study performed between 2009-2019 at Istanbul University-Cerrahpasa, Cerrahpasa School of Medicine. All patients were divided into three main groups: pyogenic (PVO), tuberculous (TVO) and brucellar (BVO). Results: A total of 100 cases were included in this study. Of these 100 patients, 59 had pyogenic, 15 had brucellar and 26 had tuberculous spondylodiscitis. The disease developed postoperatively in 22 (37.4%) of the 59 PVO cases. The common isolated microorganism was Staphylococcus aureus (n = 11), followed by coagulase negative staphylococci (n = 6). BVO rate was lower than previous case series (15 vs. 24). The median time to improvement in the laboratory findings after the administration of the appropriate treatment was 14 days. PET-CT was diagnostic in 81.8% of PVO patients, similar to MRI. However, PET-CT diagnosis rate was significantly low in TVO patients (3 out of 9, p = 0.040). Conclusion: S. aureus remained the most common etiologic agent. Coagulase negative staphylococci infection rate, mainly related to spinal surgery, and postoperative spondylodiscitis rate is higher than before. Brucellar VO rate is lower, which is mostly related to effective animal vaccination and pasteurization. Although, MRI is the gold standard, PET-CT is a promising technique in diagnosis for PVO.

Introduction: We aimed to determine the indicators for poor long-term outcome in older adults with community-acquired pneumonia (CAP). Methodology: Patients with CAP requiring hospitalization were included in this retrospective study. The long-term mortality was defined as all-cause 1-year mortality following hospital admission. Results: A total of 145 patients with CAP were recorded. The median age was 70 (18-103), of whom 94 (65%) were ≥ 65 years old and 86 (59.5%) were male. Long-term mortality rates following CAP requiring hospitalization were substantially high in both the younger (n = 16, 31.4%) and older adults (n=43, 45.7%). In univariate analysis, the Pneumonia Severity Index (PSI) (p = 0.007), mechanical ventilation (p > 0.001), mental status changes (p = 0.018) as well as the modified Charlson Comorbidity Index (p=0.001), presence of malignancy (p < 0.001) and hospital readmission (p < 0.001) were associated with long-term mortality in the older group. Our results revealed that the need for mechanical ventilation (OR = 47.61 CI = 5.38-500.0, p = 0.001) and hospital readmission (OR = 15.87 CI = 5.26-47.61, p < 0.001) were major independent predictors of 1-year mortality. Conclusions: Clinicians should consider the lethal possibilities of CAP even after hospital discharge. The need for mechanical ventilation and hospital readmission may predict long-term mortality. Therefore, the patients who have these predictors should be closely monitored.

Introduction: We aimed to evaluate clinical and laboratory findings of hospitalized asthma and chronic obstructive pulmonary disease (COPD) patients with COVID-19 and demonstrate that they have different symptoms and/or laboratory results and outcomes than COVID-19 patients with comorbidity (CoV-com) and without comorbidity (CoV-alone). Methodology: The data of the demographic, clinical, laboratory findings of hospitalized CoV-alone, asthma, COPD patients with COVID-19 (CoV-asthma, CoV-COPD, respectively), and CoV-com were analyzed. Results: Out of 1082 patients hospitalized for COVID-19, 585 (54.1%) had CoV-alone, 40 (3.7%) had CoV-asthma, 46 (4.3%) had CoV-COPD and 411 (38%) had CoV-com. Cough, shortness of breath, fever and weakness were the most common four symptoms seen in all COVID-19 patients. Shortness of breath, myalgia, headache symptoms were more common in CoV-asthma than the other groups (p < 0.001, p < 0.01, p < 0.05 respectively). Sputum was more common in CoV-COPD than other groups (p < 0.01). COPD group most frequently had increased values, different from the other groups with CRP>5ng/mL in 91.3%, D-dimer > 0.05mg/dL in 89.1%, troponin > 0.014micg/L in %63.9, INR>1.15 in 52.2%, CK-MB>25U/L in 48.5%, PT>14s in 40.9% of patients (p < 0.05, p < 0.001, p < 0.001, p < 0.001, p < 0.05, p < 0.001, respectively). NT-ProBNP was found to have the highest AUC value and the best differentiating parameter for CoV-asthma from CoV-alone. Typical CT findings were present in 44.4% of CoV-alone, 57.5% of CoV-asthma, 28.3% of CoV-COPD and 38.9% of CoV-com groups. CoV-COPD and CoV-com patients died more frequently than other groups (17.8%, 18.5%). Conclusions: CoV-asthma and CoV-COPD patients might have different symptoms and laboratory parameters than other COVID-19 patients which can guide the physicians.

Introduction This study aims to evaluate the cost-effectiveness of remdesivir compared to other existing therapies (SoC) in Turkey to treat COVID-19 patients hospitalized with < 94% saturation and low-flow oxygen therapy (LFOT) requirement. Methods We compared remdesivir as the treatment for COVID-19 with the treatments in the Turkish treatment guidelines. Analyses were performed using data from 78 hospitalized COVID-19 patients with SpO(2) < 94% who received LFOT in a tertiary healthcare facility. COVID-19 episode costs were calculated for 78 patients considering the cost of modeled remdesivir treatment in the same group from the payer's perspective. The incremental cost-effectiveness ratio (ICER) per quality-adjusted life-year (QALY) was calculated for remdesivir versus the SoC for the population identified. For Turkey, a reimbursement threshold value between USD 8599 (1 x per capita gross domestic product-GDP) and USD 25.797 (3 x GDP) per QALY was used. Results In the remdesivir arm, the length of hospital stay (LOS) was 3 days shorter than the SOC. The low ventilator requirement in the remdesivir arm was one factor that decreased the QALY disutility value. In patients who were transferred to intensive care unit (ICU) from the ward, the mean LOS was 17.3 days (SD 13.6), and the mean cost of stay was USD 155.3/day (SD 168.0), while in patients who were admitted to ICU at baseline, the mean LOS was 13.1 days (SD 13.7), and the mean cost of stay was USD 207.9/day (SD 133.6). The mean cost of episode per patient was USD 3461.1 (SD 2259.8) in the remdesivir arm and USD 3538.9 (SD 3296.0) in the SOC arm. Incremental QALYs were estimated at 0.174. Remdesivir treatment was determined to be cost saving vs. SoC. Conclusions Remdesivir, which results in shorter LOS and lower rates of intubation requirements in ICU patients than existing therapies, is associated with higher QALYs and lower costs, dominating SoC in patients with SpO(2) < 94% who require oxygen support.

Background CoronaVac, an inactivated whole-virion SARS-CoV-2 vaccine, has been shown to be well tolerated with a good safety profile in individuals aged 18 years and older in phase 1/2 trials, and provided a good humoral response against SARS-CoV-2. We present the interim efficacy and safety results of a phase 3 clinical trial of CoronaVac in Turkey. Methods This was a double-blind, randomised, placebo-controlled phase 3 trial. Volunteers aged 18-59 years with no history of COVID-19 and with negative PCR and antibody test results for SARS-CoV-2 were enrolled at 24 centres in Turkey. Exclusion criteria included (but were not limited to) immunosuppressive therapy (including steroids) within the past 6 months, bleeding disorders, asplenia, and receipt of any blood products or immunoglobulins within the past 3 months. The K1 cohort consisted of health-care workers (randomised in a 1:1 ratio), and individuals other than health-care workers were also recruited into the K2 cohort (randomised in a 2:1 ratio) using an interactive web response system. The study vaccine was 3 mu g inactivated SARS-CoV-2 virion adsorbed to aluminium hydroxide in a 0.5 mL aqueous suspension. Participants received either vaccine or placebo (consisting of all vaccine components except inactivated virus) intramuscularly on days 0 and 14. The primary efficacy outcome was the prevention of PCR-confirmed symptomatic COVID-19 at least 14 days after the second dose in the per protocol population. Safety analyses were done in the intention-to-treat population. This study is registered with ClinicalTrials.gov (NCT04582344) and is active but no longer recruiting. Findings Among 11 303 volunteers screened between Sept 14, 2020, and Jan 5, 2021, 10 218 were randomly allocated. After exclusion of four participants from the vaccine group because of protocol deviations, the intention-to-treat group consisted of 10 214 participants (6646 [65.1%] in the vaccine group and 3568 [34.9%] in the placebo group) and the per protocol group consisted of 10 029 participants (6559 [65.4%] and 3470 [34.6%]) who received two doses of vaccine or placebo. During a median follow-up period of 43 days (IQR 36-48), nine cases of PCR-confirmed symptomatic COVID-19 were reported in the vaccine group (31.7 cases [14.6-59.3] per 1000 person-years) and 32 cases were reported in the placebo group (192.3 cases [135.7-261.1] per 1000 person-years) 14 days or more after the second dose, yielding a vaccine efficacy of 83.5% (95% CI 65.4-92.1; p, TUSEB, We are grateful to all participants who volunteered to be part of this study and to all members of the clinical research teams of the participating sites.

Objectives Vaccination against COVID-19 emerges as an effective strategy for combating the pandemic. While many of our patients with rheumatic diseases (RD) wonder whether it is safe to get the vaccine, vaccine hesitancy is rising among the general population. We assessed the willingness to get vaccination and its probable predictors among patients with RD compared to healthcare workers and a sample from the general population. Methods We conducted a web-based questionnaire survey in a cross-sectional design in 3 groups of participants just before the mass vaccination program in Istanbul, Turkey. The questionnaire sought socio-demographic variables, COVID-19 related risk factors, willingness to get vaccination, and concerns and thoughts about vaccine. COVID-19 anxiety scale (CAS) was also evaluated. Results We studied in total 732 patients with RD (Group 1), 763 individuals representing general population (Group 2) and 320 hospital workers (Group 3). Dysfunctional anxiety related to COVID-19 was found in 4.9%, 3.8% and 4.1%, in Group 1, 2 and 3, respectively. Of the patients with RD, 29.2% were willing to be vaccinated, 19.0% were unwilling and 51.8% were undecided. These were somewhat similar among the general population (yes: 34.6%, no: 23.3% and unsure: 42.1%), with significantly less undecided individuals (p

Objectives: Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) is a recommended and widely used regimen for HIV infection. In this study, we aimed to determine the efficacy and safety of E/C/F/TAF in people living with HIV (PLWH), who are either treatment-naïve or switched from any tenofovir disoproxil fumarate-containing regimen. For switched patients, we aimed to determine the impact of switching from tenofovir disoproxil fumarate (TDF) to TAF on lipid profile and kidney functions. Methods: ACTHIV-IST Study Group produced a database, and five dedicated HIV centres in Istanbul entered data of PLWH who switched from any TDF-containing regimen to E/C/F/TAF and treatment-naïve patients who were initiated with the E/C/F/TAF regimen between January 2017 and December 2019. Clinical findings, viral parameters, lipid studies, renal function tests, adverse events and adherence to the treatment were recorded in this prospective observational study. Results: The study included a total of 614 switched and treatment-naïve patients. Of 430 treatment-experienced patients, 89% (382) were men, and the mean age was 42 ± 12 years. Among them, 47% (181/382) self-identified as men who have sex with men (MSM). The median duration of HIV diagnosis was 54 ± 29 months. The median duration of E/C/F/TAF use was 20 ± 36 months and that of previous treatment was 23 ± 18 months. HIV-RNA was undetectable at baseline and month 12 in 84.1% (360/428) and 86.1% (328/381) of patients, respectively ( p > 0.05). Mean CD4 counts were 708 ± 287 cells/µL and 802 ± 305 cells/µL at baseline and month 12, respectively ( p < 0.001). Serum creatinine levels remained stable during the treatment period. Mean total cholesterol levels at baseline and month 12 were 172 and 211 mg/dL ( p < 0.01), LDL-cholesterol 104 and 138 mg/dL ( p < 0.01), HDL-cholesterol 39 and 49 mg/dL ( p < 0.01) and triglycerides 134 and 174 mg/dL ( p < 0.01), respectively. The treatment was generally well tolerated. Eight patients discontinued the therapy (drug interaction: 3; lost to follow-up: 1; pregnancy: 1; pulmonary tuberculosis: 1; side effect: 1; patient’s decision: 1). Of 184 treatment-naïve patients, 88% (162) were men, and the mean age was 36.5± 12 years. Among them, 50% (81/162) self-identified as MSM. The mean duration of HIV infection was 21.6 ± 17.1 months. The mean duration of E/C/F/TAF use was 16 ± 4 months. HIV-RNA was undetectable at baseline and month 12 in 1% and 89.1% of patients, respectively. Mean CD4 counts at baseline and month 12 were 469 ± 223 cells/µL and 740 ± 298 cells/µL, respectively. During the treatment period, creatinine levels remained stable. Total cholesterol, LDL-cholesterol, triglyceride and also HDL-cholesterol levels increased. Mean total cholesterol levels at baseline and month 12 were 167 and 211 mg/dL ( p < 0.01), LDL-cholesterol 108 and 143 mg/dL ( p < 0.01), HDL-cholesterol 41 and 47 mg/dL ( p < 0.01) and triglycerides 136 and 172 mg/dL, respectively ( p < 0.01). The treatment was generally well tolerated. Three patients discontinued the therapy (drug interaction: 1; non-responder: 1; patient’s decision: 1). Conclusion: Starting with or switching to E/C/F/TAF in PLWH effectively suppresses HIV infection, is associated with an increase in CD4 cell count and is well tolerated in a real-life setting. Renal functions remained stable during the treatment. E/C/F/TAF use was associated with an increase in LDL-cholesterol and triglyceride levels along with an increase in HDL-cholesterol levels.

Candidemia is a nosocomial infection mostly found in critically ill patients. Our objectives were to evaluate the change in distribution and resistance profile of Candida spp. isolated from candidemic patients in our intensive care unit over two 5-year periods spanning 15 years and to evaluate the risk factors. Records from the microbiology laboratory were obtained, from January 2004 to December 2008 and from January 2013 to December 2017, retrospectively. Antifungal susceptibility was performed by E-test and evaluated according to EUCAST breakpoints. A total of 210 candidemia cases occurred; 238 Candida spp. were isolated in 197 patients (58.8% male; mean age, 59.2 ± 19.6 years). The most predominant risk factor was central venous catheter use. Species distribution rates were 32%, 28%, 17%, and 11% for C. albicans (n = 76), C. parapsilosis (n = 67), C. glabrata (n = 40), and C. tropicalis (n = 27), respectively. Resistance rate to anidulafungin was high in C. parapsilosis over both periods and increased to 73% in the second period. Fluconazole showed a remarkable decrease for susceptibility in C. parapsilosis (94 to 49%). The prevalence of MDR C. parapsilosis (6%/33%) and C. glabrata (0%/44%) increased in the second period. We observed a predominance of non-albicans Candida spp., with C. parapsilosis being the most frequent and C. glabrata infections presenting with the highest mortality. High level of echinocandin resistance in C. parapsilosis and increasing prevalences of MDR C. parapsilosis and C. glabrata seem emerging challenges in our institution.

Hepatitis delta virus (HDV) infection causes the most severe form of viral hepatitis. PEG-interferon alpha-2a (PEG-IFN alpha-2a) is the only effective treatment but its long-term clinical impact is unclear. the aim of this study was to investigate the long-term outcome after 48 weeks of pegylated interferon alpha-2a therapy. We performed a retrospective follow-up study of the Hep-Net-International-Delta-Hepatitis-Intervention-Study 1 (HIDIT-I trial). Patients had received 48 weeks of treatment with either PEG-IFN alpha-2a plus adefovir dipivoxil (ADV) (Group I), PEG-IFN alpha-2a alone (Group II) or adefovir dipivoxil alone (Group III). Liver-related complications were defined as liver-related death, liver transplantation, liver cancer and hepatic decompensation defined as development of Child-Pugh scores B or C or an increase in Model for End-stage Liver Disease (MELD) scores of five or more points in relation to baseline values. Patients were considered for further analysis when they were retreated with PEG-IFN alpha-2a. Follow-up data (at least 1 visit beyond post-treatment week 24) were available for 60 patients [Group I, (n = 19), Group II (n = 20), Group III (n = 21)]. Mean time of follow-up was 8.9 (1.6 - 13.4) years. 19 patients were retreated with IFN-based therapy: 42% (n = 8) in PEG-IFN alpha-2a arms and 58% (n = 11) in the adefovir only arm. Clinical complications on long-term follow-up occurred in 17 patients and were associated with nonresponse to therapy and baseline cirrhosis. the annual event-free survival rate in patients with cirrhosis vs noncirrhotic patients at year 5 and 10 was 70% vs 91% and 35% vs 76%. Long-term follow-up of a large randomized clinical trial suggests that off-treatment HDV RNA response to PEG-IFN alpha-2a treatment leads to improved clinical long-term outcome., German Centre for Infection Research (DZIF), partner site Hannover-Braunschweig; German Liver Foundation; EASL registry grant, This study was funded by the German Centre for Infection Research (DZIF), partner site Hannover-Braunschweig with a grand to the HepNet Study-House, the German Liver Foundation and an EASL registry grant.

balkan, ilker/0000-0002-8977-5931 WOS:000573999000010 Objectives: We aimed to evaluate the etiological, epidemiological and laboratory characteristics of adult patients admitted to our hospital with acute hepatitis. Materials and Methods: The patients with alanine aminotransferase (ALT) levels exceeding 10-fold and appropriately examined for etiology were included in the study The markers for hepatothropic viruses and the others, autoimmune markers and hepatobilian/ultrasound were evaluated. Results: In this study 111 patients were included, 46 (41%) were female and 41.4% of the patients had AH-A, 17.1% had AH-B, 2.7% had AH-C and 6.3% were not found any cause. The mean age was 22.11 +/- 6.05 years in AH-A. The majority of AH-A cases were male with 65%. The mean age was 33.5 +/- 14.78 in AH-B. There was a statistically significant difference between ages of patients with AH-A and AH-B (p=0.004). Conclusion: Since no specific treatment is available for acute viral hepatitis, preventive measures are more significant. The prevalence of AH-A and AH-B have declined in the recent years. It is clear that extensive vaccine policies and improved sanitation help eliminate these diseases. In order to ensure complete elimination of viral hepatitis, it is essential to give due importance to the vaccination in childhood as well as in adults.

HIV/AIDS-related stigma remains a crucial public health problem in the world. Unfortunately, health provider staffs such as nurses and physicians are the major source of stigmatization and discrimination against peoples living with HIV (PLHIVs) including in Turkey. The aim of this study was to assess HIV-related stigma towards to PLHIV by nurses and physicians and to examine related factors. Descriptive Assessment Form and the HIV-Related Stigma Scale used for data collection. The study consisted of 405 health workers including 251 nurses and 154 physicians. Over 86% of physicians and 69.3% of nurses had no specific education about HIV. More than 11% of the nurses and 8.4% of the physicians expressed that HIV can be transmitted with handshaking or breathing in a shared environment. Fear-driven stigma was significantly different by age, education, occupation, and work experience. Over 14% of the discrimination (Adjusted

Myroides spp. are opportunistic environmental Gram-negative bacteria. These affect mostly immunocompromised hosts and generally lead to soft tissue, and urinary tract infections. Bacteremia most commonly develop secondary to soft tissue or catheter related infections and may lead rarely to mortality. Myroides spp. are generally suscetible to fluoroquinolones, piperacillin/tazobactam, trimethoprim/sulfamethoxazole, carbapenems or tetracyclines however, pan-resistant isolates and multiple resistance genes have been reported in clinical isolates of Myroides spp. We report a pan-resistant Myroides odoratimimus bacteremia in a patient with severe COVID-19 ending with fatality and in this context a review of reported Myroides bacteremias are also described. In this study, a 64-year old male patient with history of coronary artery bypass was admitted to ICU with severe COVID-19 pneumonia accompanied by pneumomediastinum and pneumopericardium. Continous renal replacement therapy and extracorporeal membraneous-oxygenation were initiated due to acute renal failure and persistent hypercarbia/hypoxia, respectively. Within four weeks of hospitalization various episodes of bacteremia developed and multiple antibiotics were used. On the 5th week of follow-up, acute phase reactants increased and empirical broad spectrum antibiotics were initiated. Blood culture revealed Gram-negative rods. The patient became hypotensive and despite maximum medical care he was lost due to cardiac arrest. M. odoratimimus was identified by MALDI-TOF and the bacterium was pan-resistant. According to Center for Genomic Epidemiology results the strain was identified as M. odoratimimus PR63039 and the genome analysis revealed antibiotic resistance genes associated with resistance to beta-lactams (bla OXA-347, bla MUS-1, bla EBR-1), tetracyclines (tetX), sulfonamides (sul2), macrolides (ereD), (ermF).

Background: Efficacy of elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil (E/C/F/TDF) in treatment-naïve and experienced patients with HIV infection was demonstrated in phase 3 trials. The primary objective of this study was to evaluate effectiveness and safety of E/C/F/TDF in real world settings. Methods: Retrospective, observational data collected by the Turkish ACTHIV-IST study group between May 2015 and December 2016 were analysed. Results: A total of 387 patients were prescribed E/C/F/TDF; 210 patients with available data at 6th month were eligible; 91.5% were male, and mean age was 35.2 (SD: 10.8) years; 54.0% of males identified themselves as MSM. Sixty-three percent (133) of the study population were treatment-naïve patients, and 37% (77) were treatment experienced. HIV RNA level was below 100 copies/mL in 78.9% of treatment-naïve patients and 89.9% of treatment experienced patients at month 6. Median increase in CD4 T lymphocyte count was 218 copies/mL in treatment-naïve patients and remained stable or increased in treatment experienced patients. Adverse events were observed in 15% of the patients, and the regimen was discontinued in only six patients. Conclusion: Real world data on the effectiveness and safety of E/C/F/TDF is comparable with the phase 3 trial results Adverse events are uncommon and manageable. Keywords: Elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate; HIV; effectiveness; safety.

We aimed to explore long-term results of oral antiviral agents in treatment-naïve "HBeAg negative chronic hepatitis B (CHB)" and determine the factors affecting the complete virological response.Patients with HBeAg-negative CHB who used oral antiviral agents for at least 3 years were evaluated retrospectively.A total of 173 patients were recorded. The mean duration of treatment was 62.2 ± 28.9 months. Complete virological responses (CVR) were 82.8% (n = 53/64) in tenofovir disoproxil fumarate (TDF), 84.4% (n = 49/58) in lamivudine (LAM), 83.9% (n = 26/31) in entecavir (ETV), 95% in telbivudine (LdT) (n = 19/20) (p = 0.290). Multivariate analysis revealed age ≤ 40 (p = 0.012, 95%CI = 1.38-13.76, OR = 4.36) and baseline HBV DNA value (p = 0.003, 95%CI = 1.23-2.63, OR = 1.78) as independent factors for CVR. Virological breakthrough was detected in 29 (50%) patients on LAM therapy, two (6.4%) patients on ETV therapy, and two (10%) patients on LdT therapy. Treatment was switched to another antiviral agent due to osteoporosis in four patients in the TDF group, muscle pain in nine patients in the LDT group, and headache in one patient in the ETV group. Hepatocelluler cancer was detected in five patients. HBsAg seroclearance developed in two patients. Anti-HBs seroconversion was not detected.CVR was achieved at similar rates with all four antiviral agents, while younger age (≤ 40) and low baseline viral load were the main factors for virological response. However, drug resistance and virological breakthrough in the LAM group and side effects in the LdT group were detected during the long-term follow-up. Moreover, HBsAg seroclearance was achieved at very low rates with oral antiviral agents.

Most of the published data relate to classical forms of rheumatic diseases (RD) and information on rare inflammatory disorders such as Behçet's syndrome (BS) and familial Mediterranean fever (FMF) is limited. We studied the frequency of side effects and disease flares after COVID-19 vaccination with either Pfizer/BioNTech or Sinovac/CoronaVac in 256 patients with BS, 247 with FMF, and 601 with RD. Telephone interviews were conducted using a questionnaire survey in a cross-sectional design in patients with BS, FMF, and RD followed by a single university hospital. Study participants were vaccinated either with CoronaVac (BS:109, FMF: 90, and RD: 343,) or BioNTech (BS: 147, FMF: 157 and RD: 258). The majority have received double dose (BS: 94.9%, FMF 92.3% and RD: 86.2%). BioNTech ensured a significantly better efficacy than CoronaVac against COVID-19 in all patient groups (BS: 1.4% vs 10.1%; FMF: 3.2% vs 12.2%, RD:2.7% vs 6.4%). Those with at least one adverse event (AE) were significantly more frequent among those vaccinated with BioNTech than those with CoronaVac (BS: 86.4% vs 45%; FMF: 83.4% vs 53.3%; and RD: 83.3% vs 45.5%). The majority of AEs were mild to moderate and transient and this was true for either vaccine. There were also AEs that required medical attention in all study groups following CoronaVac (BS: 5.5%, FMF: 3.3%, and RD:2.9%) or BioNTech (BS: 5.4%, FMF: 1.9%, and RD: 4.7%). The main causes for medical assistance were disease flare and cardiovascular events. Patients with BS (16.0%) and FMF (17.4%) were found to flare significantly more frequently when compared to those with RD (6.0%) (p 0.001). This was true for either vaccine. BS patients reported mainly skin-mucosa lesions; there were however, 11 (4.3%) who developed major organ attack such as uveitis, thrombosis or stroke. Flare in FMF patients were associated mainly with acute serositis with or without fever. Arthralgia/arthritis or inflammatory back pain were observed mainly in the RD group. Our study demonstrates that BS and FMF patients vaccinated with either CoronaVac or BioNTech demonstrated similar AE profile and frequency compared to RD patients. AEs that required physician consultation or hospitalization occurred in all study groups after either CoronaVac or BioNTech. Increased frequency of flares in BS and FMF compared to that seen in RD might reflect defects in innate immunity and deserves further investigation. Caution should be required when monitoring these patients after vaccination.

Introduction: People who inject drugs (PWID) should be treated in order to eliminate hepatitis C virus (HCV) in the world. Aims: The aim of this study was to compare direct acting antivirals (DAAs) treatment of HCV for PWID and non-PWID in real life setting. Materials and methods: We performed a prospective, non-randomized, observational multi-center cohort study in 37 centers. All patients treated with DAAs therapy between April 1, 2017 to February 28, 2019 were included. In total, 2,713 patients were included in the study among which 250 were PWID and 2,463 were non-PWID. Besides patient characteristics, treatment response, follow-up and side effects of treatment were also analyzed. Results: Genotype 1a and 3 were more prevalent in PWID infected patients (20.4% vs 9.9% and 46.8% vs 5.3%). The number of naïve patients was higher in PWID (90.7% vs 60.0%), while the number of patients with cirrhosis was higher in non-PWID (14.1% vs 3.7%). The loss of follow up was higher in PWID (29.6% vs 13.6%). There was no difference in the sustained virologic response at 12 weeks after treatment (98.3% vs 98.4%), but the end of treatment response was lower in PWID (96.2% vs 99.0%). In addition, the rate of treatment completion was lower in PWID (74% vs 94.4%). Conclusion: DAAs were safe and effective in PWID. Primary measures should be taken to prevent the loss of follow-up and poor adherence in PWID patients in order to achieve World Health Organization’s objective of eliminating viral hepatitis.

Background: Widespread and effective use of molecular diagnostic tests is indispensable for protecting public health and containing the severe respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. More than 1 year into the pandemic, as resources have reached a point of depletion, grouping samples in pools of certain sizes appears to be a reasonable method to reduce both the costs and the processing time without necessitating additional training, equipment, or materials. Aims: To assess whether the pooling strategy that was used in past outbreaks and is used in blood tests prior to transfusion for screening large populations can also be used in SARS CoV-2 tests. Study Design: Diagnostic accuracy study. Methods: This prospective study was conducted with 2815 samples, sent to the coronavirus disease 2019 (COVID-19) Laboratory of our hospital between February 12 and 21, 2021, to be tested for the presence of SARS-CoV-2. The samples were examined individually and in pools of five 100 µl taken from each sequential sample, using 3 different SARS-CoV-2 reverse transcription-polymerase chain reaction (RT-PCR) kits, the Allplex™ 2019-nCoV Assay kit (Seegene, Republic of Korea), the GeneMAP™ 2019-nCoV detection V.3 kit (GenMark, Türkiye), and the Bio-Speedy™ SARS-CoV-2 Double Gene™ RT-qPCR kit (Bioeksen, Türkiye) on the BioRAD CFX96™ Touch (Bio-Rad Laboratories Inc., Hercules, CA, USA) platform available in our laboratory. Results: Following the extraction of serial dilutions prepared from the SARS-CoV-2 RNA positive (cycle of threshold: 20) sample, the standard curves of RT-PCR were analyzed. By evaluating the efficiency (E) values, all 3 kits showed high sensitivity and similar results; while the highest level was detected with the Allplex™ 2019-nCoV Assay kit in the nucleocapsid (N) gene (E: 124%), the lowest was detected with the Double Gene™ RT-qPCR kit in the N and ORF 1ab genes (E: 90%). Of the samples included in the study, only 1 positive sample with low viral load was found to be negative when studied by pooling. The total number of kits to be used in pooled tests and then to individually retest the 5 samples in positive pools was calculated as 827 and the savings rate as 69.91% (1968/2815). Conclusion: The pooling strategy is an effective approach to extend the impact of limited testing resources and reagents available in certain periods of the COVID-19 pandemic. Testing by pooling samples requires improvement of RNA extraction methods and careful monitoring of RT-PCR test sensitivity to avoid missing low-positive entities. Therefore, based on the prevalence of COVID-19 in their regions, laboratories should conduct their own validation of pooling studies for RNA extraction and amplification methods they use.

Initial case series of small number of patients at the beginning of the pandemic reported a rather guarded prognosis for Behçet’s syndrome (BS) patients infected with SARS-CoV-2. In this prospective study, we describe the incidence, clinical characteristics, disease course, management, and outcome in a large cohort of BS patients with laboratory-confirmed infection of SARS-CoV-2. We defined a cohort of 1047 registered BS patients who were aged between 16 and 60 years and seen routinely before the pandemic at the multidisciplinary outpatient clinic. We followed prospectively this cohort from beginning of April 2020 until the end of April 2021. During 13 months of follow-up, of the 1047 (599 M/448 F) patients, 592 (56.5%) were tested for SARS-CoV-2 PCR at least once and 215 (20.5%; 95% CI 0.18–0.23) were tested positive. We observed 2 peaks which took place in December 2020 and April 2021. Of the 215 PCR positive patients, complete information was available in 214. Of these 214, 14 (6.5%) were asymptomatic for COVID-19. In the remaining, the most common symptoms were anosmia, fatigue, fever, arthralgia, and headache. A total of 40 (18.7%) had lung involvement, 25 (11.7%) were hospitalized, 1 was admitted to the intensive care unit while none died. Favipiravir was the most prescribed drug (74.3%), followed by colchicine (40.2%), and hydroxychloroquine (20.1%) in the treatment of COVID-19. After COVID-19, 5 patients (2.3%) were given supplemental O2 and 31 (14.5%) antiaggregant or anticoagulants. During COVID-19, of the 214 PCR positive patients, 116 (54.2%) decreased the dose of their immunosuppressives or stopped taking completely; 36 (16.8%) experienced a BS flare which was mostly oral ulcers (10.3%). None of the patients reported a thrombotic event. A total of 93 (43.5%) patients reported BS flares after a median 45 days of COVID-19 infection and this was found to be significantly associated with immunosuppressive drug discontinuation. Multiple regression analysis adjusted for age and gender indicated that smoking and using interferon-alpha decreased the likelihood of getting COVID-19. The incidence and severity of COVID-19 did not differ between those who were using colchicine or not. The cumulative incidence of COVID-19 in this prospectively followed cohort of BS patients was almost two folds of that estimated for the general population living in Istanbul, Turkey, however, the clinical outcome of COVID-19 was not severe and there was no mortality. The protective effect of smoking and interferon deserves further investigation. On the other hand, colchicine did not have any positive or negative effect against COVID-19. Significant number of patients flared after COVID-19, however, this was significantly associated with immunosuppressive discontinuation during the infection. Contrary to our previous observations, COVID-19 did not seem to exacerbate thrombotic events during or after the infection.

Aims In this study, we aimed to reveal mortality rates and factors affecting survival in geriatric patients infected with COVID-19. Methods This is a retrospective study of 873 geriatric patients with COVID-19 who were hospitalized between March 11, 2020 and March 11, 2021. Demographic, clinical, laboratory data, and treatment options were obtained from electronic medical records. Multivariate logistic regression was used to explore the risk factors for in-hospital death. Results During the specified period, 643 patients were discharged, and 230 patients died in the hospital. The mean age was 75.08 ± 7.39 years (mean ± SD) and 51.8% were males. We found that older age (≥ 85), polypharmacy, dyspnea, abnormal thorax computed tomography (CT), lower doses of anticoagulation, and high values of white blood cell, aspartate aminotransferase, C-reactive protein, lactate dehydrogenase, ferritin were associated with a significant increase in mortality (P

Aims: The COVID-19 pandemic has substantially changed lives and presented several barriers to health services. HIV care continuum needs a high rate of diagnosis, effective treatment, and sustained suppression of viral replication. The COVID-19 pandemic has affected these three steps of HIV care. This study investigated the characteristics of newly diagnosed patients living with HIV/AIDS (PLWH) during the COVID pandemic and compared them with those before the pandemic. Methods: All newly diagnosed patients in three HIV healthcare centers, in Istanbul, Turkey, were included in the study. The pandemic period included April 1, 2020, to April 1, 2021, and the prepandemic period included March 1, 2019, to March 1, 2020. Results: 756 patients were diagnosed with HIV/AIDS. In the pandemic period, this figure was 58% less: 315. Patients in the pre-pandemic and pandemic period had comparable age and gender distributions. PLWH diagnosed in the pandemic period had higher rates of low CD4 cells: low CD4 ( Conclusion: A low number of newly diagnosed PLWH can be explained by less HIV testing, less admission to health care, or an actual decrease of HIV prevalence during the pandemic. Sexual behaviors may have changed during the COVID-19 pandemic, leading to HIV transmission restriction. Lower CD4 counts among the newly diagnosed PLWH suggest that admittance to health care is late and a significant portion of PLWH remain undiagnosed.

Limited data exists to date on the predictors for the development of pneumonia in patients with mild and moderate coronavirus (COVID-19). In this study, it was aimed to evaluate the demographic characteristics and clinical findings of mild and moderate COVID-19 and to determine the risk factors for the development of COVID-19 pneumonia in patients admitted to the pandemic outpatient clinic of a university hospital. A total of 414 patients with laboratory confirmed COVID-19 were included. Of these, 220 (53.1%) were male, the mean age was 38.3 ± 12.7. Median duration of hospital admission from the onset of symptoms was three days (0-11). Of the confirmed COVID-19 cases, 154 (37.2%) had a history of family contact and the most common symptoms were weakness (68.4%), myalgia (61.8%), headache (56.5%), loss of smell (45.2%), loss of taste (43.2%) and anorexia (42.8%). Among females, weakness (p= 0.016), headache (p= 0.008), sore throat (p= 0.032), nausea (p= 0.003), anorexia (p= 0.045), loss of taste (p= 0.005) and loss of smell (p0.001) were more common. Loss of taste (47.6% vs. 25%, p0.001) and loss of smell (50% vs. 26.3%, p0.001) were more common in patients with under the age of 50 and cough (43.4% vs. 29.3%, p= 0.003) was more common in patients with above the age of 40. Among 46 (11.1%) patients with asymptomatic COVID-19, there was no significant difference (p= 0.500) between the genders. Pneumonia was detected in 150 (43.8%) of 339 patients who underwent thorax computed tomography. In the univariate analysis; advanced age (p0.001, odds ratio (OR)= 1.44), obesity (p0.001 OR= 2.5), not being actively smoking (p0.001, OR= 6.19), fever at first admission (p= 0.002, OR= 2.02), cough (p0.001, OR= 3.26), shortness of breath (p0.001, OR= 23.37), weakness (p= 0.042, OR= 1.63), anorexia (p= 0.009, OR= 1.79) and elevation of D-dimer (p= 0.014, OR= 1.92) were associated with the development of pneumonia. In multivariate analysis, obesity (p= 0.005, OR= 2.69), not being actively smoking (p0.001, OR= 5.43), cough at first admission p= 0.017, OR= 2.16) and shortness of breath (p= 0.008, OR= 16.22) was determined as an independent risk factor for the development of pneumonia. CRP (p0.001), D-dimer (p0.001), ferritin (p0.001) values among 108 (26.1%) patients with a body-mass index(BMI)30 were high, and 60.9% of the patients had pneumonia (p0.001) . CRP (p0.001), D-dimer (p= 0.010) values were low, lymphocyte count (p= 0.001) was high among 106 (25.6%) active smokers, and 15.6% of the patients had pneumonia (p0.001). Of the patients reported with persistent symptoms, 25.9% had loss of smell, 25% had weakness, and 23.1% had loss of taste on the seventh day; 21.1% had loss of smell, 21.1% had myalgia, and 19.7% had loss of taste on the 14th day. During their follow-up, the COVID-19 polymerase chain reaction (PCR) test was studied in 286 patients for control purposes. The median time of being negative for COVID-19 PCR test was eight days (3-56). In conclusion, symptoms may last longer than 14 days in 20- 30% of patients presenting with mild-moderate clinical findings. In addition, obesity should be considered as an important risk factor for COVID-19 pneumonia.
