Abstract   Background and aim Viral load is used for the diagnosis and monitoring the treatment of chronic hepatitis B (CHB). These methods are molecular-based and are expensive. Previous studies suggest that quantitative hepatitis B surface antigen (HBsAg) studied by automated chemiluminescent microparticle immunoassay can be a surrogate marker. In this study, we aimed to investigate whether quantitative HBsAg correlates hepatitis B virus (HBV) DNA levels during CHB treatment. Methods The study included 18 patients (13 male, 5 female, mean age: 33 ± 9 years) with CHB. They were given pegylated interferon ± lamivudine for 52 months and serum samples were obtained in weeks 0, 4, 8, 24, 48, 52, and 76. HBV DNA was measured by TaqMan polymerase chain reaction (PCR; Erasmus MC, University Medical Center, Rotterdam, The Netherlands). Quantitative HBsAg was studied by automated chemiluminescent microparticle immunoassay (Architect HBsAg, Abbott, IL). Results HBV DNA levels were measured as follows: 9.66, 7.69, 7.06, 5.93, 5.89, 5.88, and 7.27 logarithmic genome equivalent/ml, respectively. The corresponding HBsAg quantitation results were 42,888, 31,176, 37,882, 27,277, 28,279, 29,471, and 31,535 IU/ml, respectively. They showed a significant correlation (canonical correlation = 0.85). Conclusions HBsAg studied by automated chemiluminescent microparticle immunoassay correlates with HBV DNA and can be a surrogate marker during the monitoring of the efficacy of HBV treatment.

Hepatitis C virus (HCV) is the most common chronic blood-borne infection in the worldwide. This infection is often insidious and one-half of infected patients are asymptomatic. Determination of risk factors for HCV transmission is very important. The aim of this study was to assess the risk factors, transmission to spouses and children for HCV infection in Turkish population. One hundred and fifty-one patients with chronic hepatitis C and 151 control cases were investigated for the probable risk factors of HCV infection. Complete blood count, ALT, AST, albumin, prothrombin time, upper abdomen ultrasonography assessment and percutaneous liver biopsy (not for cirrhotics) were performed in all patients with chronic hepatitis C. Anti-HCV testing was done by using second-generation ELISA in 302 cases. Minor surgical operation (p< 0.001), major surgical operation (p= 0.001), blood transfusion (p< 0.001), multi-partner sex (p< 0.05), frequent dental therapy (p< 0.05), and dental extraction (p< 0.001) in patients with a chronic HCV infection were found to be higher than the control group. No significant difference was found in other risk factors. The rate of hepatitis C virus in index cases was found to be 1.8% in their spouses and 1.2% in their children. Our study showed that surgical operation, frequent dental therapy, dental extraction, multi-partner sex, and blood transmission are the main risk factors for HCV infection in Turkish community.

Abstract  Hydatid disease involving the vertebral body and paravertebral soft tissues is rare even in rural areas where echinococcosis is endemic. The case of a 34-year-old woman with vertebral hydatid disease mimicking tuberculous spondylodiscitis (Pott's disease) is presented in this report. Spinal hydatid disease should be considered in the differential diagnosis of spondylodiscitis in endemic countries, and tested for with imaging and serology. [ABSTRACT FROM AUTHOR]

Objective: Urinary tract infections (UTIs) due to extended-spectrum betalactamase (ESBL) producing Escherichia coli and Klebsiella pneumoniae are among the leading causes of morbidity and mortality in older adults. Identifying associated factors for ESBL production may contribute to more appropriate empirical treatment. Materials and methods: This was a prospective observational study. Hospitalized patients of age > 65 with community-onset or hospital-acquired upper UTI due to E. coli or Klebsiella pneumoniae were included. A multivariate analysis was performed. Results: A total of 97 patients were included. ESBL prevalence among UTIs with E. coli or Klebsiella pneumoniae was 69.1% (n = 67). CRP values at the time of UTI diagnosis were found to be significantly higher in the ESBL-producing group (p = 0.004). The multivariate analysis revealed that male gender (OR: 2.72, CI: 1.02-7.25), prior recurrent UTI (OR: 3.14, CI: 1.21-8.14), and the development of secondary bacteremia (OR: 4.95, CI: 1.03-23.89) were major associated factors for UTI in older adults due to ESBL-producing E. coli and Klebsiella pneumoniae. Conclusion: Severe UTI in older men with a history of recurrent UTI may be a warning to the clinician for ESBL production in the setting of high ESBL prevalence. Carbapenems may be prioritized in the empirical treatment of patients with known risk factors for ESBL. [ABSTRACT FROM AUTHOR]

Introduction: XAV-19 is a glyco-humanized swine polyclonal antibody targeting SARS-CoV-2 with high neutralizing activity. The safety and clinical efficacy of XAV-19 were investigated in patients with mild to moderate COVID-19. Methods: This phase II/III, multicentric, randomized, double-blind, placebocontrolled clinical trial was conducted to evaluate the safety and clinical efficacy of XAV-19 in patients with a seven-point WHO score of 2 to 4 at randomization, i.e., inpatients with COVID-19 requiring or not requiring lowflow oxygen therapy, and outpatients not requiring oxygen (EUROXAV trial, NCT04928430). Adult patients presenting in specialized or emergency units with confirmed COVID-19 and giving their consent to participate in the study were randomized to receive 150 mg of XAV-19 or placebo. The primary endpoint was the proportion of patients with aggravation within 8 days after treatment, defined as a worsening of the seven-point WHO score of at least one point between day 8 and day 1 (inclusion). The neutralization activity of XAV-19 against variants circulating during the trial was tested in parallel. Results: From March 2021 to October 2022, 279 patients received either XAV-19 (N = 140) or placebo (N = 139). A slow enrollment and a low rate of events forced the termination of the premature trial. XAV-19 was well tolerated. Underpowered statistics did not allow the detection of any difference in the primary endpoint between the two groups or in stratified groups. Interestingly, analysis of the time to improvement (secondary endpoint) showed that XAV-19 significantly accelerated the recovery for patients with a WHO score of 2 or 3 (median at 7 days vs. 14 days, p = 0.0159), and even more for patients with aWHO score of 2 (4 days vs. 14 days, p = 0.0003). The neutralizing activity against Omicron and BA.2, BA.2.12.1, BA.4/5, and BQ.1.1 subvariants was shown. Discussion: In this randomized placebo-controlled trial with premature termination, reduction of aggravation by XAV-19 at day 8 in patients with COVID-19 was not detectable. However, a significant reduction of the time to improvement for patients not requiring oxygen was observed. XAV-19 maintained a neutralizing activity against SARS-CoV-2 variants. Altogether, these data support a possible therapeutic interest for patients with mild to moderate COVID-19 requiring anti-SARS-CoV-2 neutralizing antibodies. [ABSTRACT FROM AUTHOR]

Objectives: Hepatitis B virus (HBV), one of the biggest health problems of the world and our country, still constitutes the largest cause of liver failure and liver transplantation in the world. Here, we will introduce the HBV virus closely and share the health problems of HBV in the world and in our country in the literature data. Methods: İnönü University Liver Transplant Institute Patients who underwent liver transplantation due to any reason related to HBV were included in the study. Patients who underwent liver transplantation due to liver diseases caused by HBV in our institute between 2009 and 2023 were included in the study. . A total of 3679 patients underwent liver transplantation between 2002 and 2024. Of these patients, 1275 patients were operated on with the diagnosis of HBV. When 530 patients whose data were not available and 49 patients who were retransplanted were excluded from the study, a total of 695 patients were included in the study. Results: Treatment is given in combination with antiviral and HBIG. It is available in centers where powerful antivirals are used alone. Although the approaches of the centers vary, patients who have had a liver transplant due to HBV definitely need postoperative medical treatment to prevent HBV recurrence. Conclusion: Patients who have undergone liver transplantation due to HBV must have their Hbs-ag level checked when they are discharged from the hospital. Informing the patient about HBV recurrence and medical treatment provides a more meticulous medical treatment. [ABSTRACT FROM AUTHOR]

Introduction: The purpose of the study was to determine the volume and extent of general human immunodeficiency viruses (HIV)/acquired immunodeficiency syndrome (AIDS) research in Turkey as well as the coverage of national HIV/AIDS research agenda. Material and methods: Web of Science (WoS) Core Collection advanced search engine was applied to conduct bibliometric search. "HIV or AIDS or HIV/AIDS or Human immunodeficiency virus or HIV-1 or HIV-2 or acquired immunodeficiency syndrome" and "Turkey" were used as search key words. In addition, the study included "Language = English", "Document area = medicine" and "Document type = Article". We also selected science citation index expanded (SCI-EXPANDED) and social sciences citation index (SSCI) as Web of Science indexes. The data in WoS improved all information on publications, including fields of study, institutions, group authors, funding agencies, journals, citations, and co-authorship. Results: In total, 313 articles were found. The first document was published in 1996, and 310 (99%) papers were published in the last 20 years. The documents were mostly (62.300%) published in science citation index expanded (SCI-EXPANDED) indexed journals. Most of the publications were from medicine general internal (33.866%) area. The top-ranked affiliations from Turkey in HIV/AIDS research were Istanbul University (19.169%), Ege University (10.863%), University of Health Sciences (9.265%), and Hacettepe University (8.626%). ACTHIV-IST (ACTion against HIV in Istanbul) study group (n = 3, 0.958) was Turkey's most productive HIV/AIDS research group. 87.220% of the studies were not funded. Conclusions: According to the findings, Turkey has limited HIV/AIDS research output. Furthermore, the majority of investigations were conducted by only a few centers. Because the study covered the entire country, and there are more centers that follow HIV/AIDS patients, these centers should also take part in the research. As a result, the current study emphasizes the importance of increasing targeted financing for HIV/AIDS research. [ABSTRACT FROM AUTHOR]

Hepatitis D virus (HDV) infection represents the most serious form of chronic hepatitis. Turkey is among the countries with high HDV and intermediate hepatitis B virus prevalence. In Turkey, hepatitis B virus (HBV) vaccine series was included in the routine vaccination program in 1998. There have been regional differences in prevalence of HBV and HDV. Although a decline in HDV prevalence is estimated, there are uncertainties about the epidemic patterns of it. HDV prevalence was studied in varying groups and geographic regions. In this study, we aimed to analyse hepatitis D epidemiology in all groups and geographic regions in recent 35 years. During the study period of 35 years, 111 publications were noted. The analysis was done on the basis of three periods: 1999 and before (Period 1), 2000–2009 (Period 2), and 2010 and after (Period 3). The groups studied included inactive carrier state, chronic hepatitis B, all HBsAg‐positive individuals and special groups. Among inactive HBV carriers, HDV prevalence did not change significantly over three decades. Among patients with chronic hepatitis, studies reported decreasing (from Period 1 to Period 2) and then increasing (from Period 2 to period 3) HDV prevalence. The studies including all HBsAg‐positive patients reported decreasing (from Period 1 to Period 2) and then increasing (from Period 2 to period 3) HDV prevalence. Cumulative data of these 3 groups were taken to reveal HDV prevalence in HBV‐infected patients, and it showed decreasing (from Period 1 to Period 2) and then increasing (from Period 2 to period 3) HDV prevalence. Cumulative data of these 3 groups analysed according to the geographic regions of the country showed that Eastern and Southeastern Anatolia regions still have a high burden of HDV. The study showed that although HDV prevalence decreased from 8.3% in Period 1 to 4.8% in Period 2, it tended to increase 5.5% in Period 3. HDV infection is still a healthcare problem in Turkey.

Aims: This study aimed to determine HIV incidence and prevalence in Turkey and to estimate the cost-effectiveness of improving testing and diagnosis in the next 20 years. Background: HIV incidence in Turkey has been rapidly increasing in the last decade with a particularly high rate of infection for younger populations, which underscores the urgent need for a robust prevention program and improved testing capacity for HIV. Methods: We developed a dynamic compartmental model of HIV transmission and progression among the Turkish population aged 15–64 and assessed the effect of improving testing and diagnosis. The model generated the number of new HIV cases by transmission risk and CD4 level, HIV diagnoses, HIV prevalence, continuum of care, the number of HIV-related deaths, and the expected number of infections prevented from 2020 to 2040. We also explored the cost impact of HIV and the cost-effectiveness of improving testing and diagnosis. Results: Under the base case scenario, the model estimated an HIV incidence of 13,462 cases in 2020, with 63% undiagnosed. The number of infections was estimated to increase by 27% by 2040, with HIV incidence in 2040 reaching 376,889 and HIV prevalence 2,414,965 cases. Improving testing and diagnosis to 50%, 70%, and 90%, would prevent 782,789, 2,059,399, and 2,336,564 infections-32%, 85%, and 97% reduction in 20 years, respectively. Improved testing and diagnosis would reduce spending between $1.8 and $8.8 billion. Conclusions: In the case of no improvement in the current continuum of care, HIV incidence and prevalence will significantly increase over the next 20 years, placing a significant burden on the Turkish healthcare system. However, improving testing and diagnosis could substantially reduce the number of infections, ameliorating the public health and disease burden aspects. [ABSTRACT FROM AUTHOR]

Background/aims: 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. Method: Patients with HBeAg-negative CHB who used oral antiviral agents for at least 3 years were evaluated retrospectively. Results: 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. Conclusion: 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. [ABSTRACT FROM AUTHOR]

There are limited data about humoral response to vaccine in Behçet's syndrome (BS). We compared SARS-CoV-2 antibody response after two doses of inactivated (Sinovac/CoronaVac) or mRNA (Pfizer/BioNTech) vaccines in patients with BS and healthy controls (HCs). We studied 166 (92M/74F) patients with BS (mean age: 42.9 ± 9.6 years) and 165 (75M/90F) healthy controls (mean age: 42.4 ± 10.4 years), in a single-center cross-sectional design between April 2021 and October 2021. A total of 80 patients with BS and 89 HCs received two doses of CoronaVac, while 86 patients with BS and 76 HCs were vaccinated with BioNTech. All study subjects had a negative history for COVID-19. Serum samples were collected at least 21 days after the second dose of the vaccine. Anti-spike IgG antibody titers were measured quantitatively using a commercially available immunoassay method. We found that the great majority in both patient and HC groups had detectable antibodies after either CoronaVac (96.3% vs 100%) or BioNTech (98.8% vs 100%). Among those vaccinated with CoronaVac, BS patients had significantly lower median (IQR) titers compared to HCs [36.5 (12.5–128.5) vs 102 (59–180), p < 0.001]. On the other hand, antibody titers did not differ among patients with BS and HCs who were vaccinated with BioNTech [1648.5 (527.0–3693.8) vs 1516.0 (836.3–2599.5), p = 0.512). Among different treatment regimen subgroups in both vaccine groups, those who were using anti-TNF-based treatment had the lowest antibody titers. However, the difference was statistically significant only among those vaccinated with CoronaVac. Among patients vaccinated with BioNTech, there was no statistically significant difference between different treatment regimen groups. Compared to inactivated COVID-19 vaccine, mRNA-based vaccine elicited higher antibody titers among BS patients. Only in the CoronaVac group, patients especially those using anti-TNF agents were found to have low titers compared to healthy subjects. BS patients vaccinated with BioNTech were found to have similar seroconversion rates and antibody levels compared to healthy controls. Further studies should assess whether the low antibody titers are associated with diminished protection against COVID-19 in both vaccine groups. [ABSTRACT FROM AUTHOR]

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 < 0.001) was found in the survival distribution in favor of the group without BSI. 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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

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).

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 < 0.001 for all). Although all of these values were significant in multivariate logistic regression analysis, the most important ones were dyspnea (Odds ratio (OR) 57.916, 95% confidence interval (CI) 23.439–143.104, P < 0.001), polypharmacy (OR 6.782, 95% CI 3.082–14.927, P < 0.001), and thorax CT classification (typical; OR 9.633, 95% CI 2.511–37.122, P < 0.001). Conclusion: Older age, polypharmacy, dyspnea, and abnormal thorax CT were the most significant mortality criteria and in addition appropriate anticoagulant use was associated with reduced mortality. Identifying the risk factors to predict mortality in older adults with COVID-19 is important to treat future cases successfully. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

We investigated the cases with Aeromonas bacteremia in terms of clinical and microbiological characteristics, underlying disease and mortality rates. Patients with positive blood cultures were included in this research. Aeromonas bacteremia was diagnosed as at least one positive blood culture for Aeromonas species. The bacteremia was defined as community origin if the onset was in the community or within 72 hours of hospital admission. The others were considered as nosocomial. All bacteria were defined as Aeromonas with conventional method. Species identification was verified by VITEK system. Antibiotic susceptibility tests were analyzed with the disc diffusion, E-test method or VITEK system. Thirty-three patients were diagnosed with bacteremia due to Aeromonas spp. Hematologic and solid tumors were the leading underlying conditions, followed by cirrhosis. Two patients (6%) had community-acquired infections. Aeromonas hydrophila was the most common isolated bacterium. The crude mortality rate was 36%. 12 patients died and 6 deaths and 4 deaths were detected in patients with bacteremia caused by A. hydrophila and Aeromonas sobria respectively. All strains were resistant to ampicillin and more than 90% of the strains were susceptible to trimethoprim-sulfamethoxazole, fluoroquinolone, third generation cephalosporins, and carbapenems. Aeromonas sp. is not a frequent cause of bacteremia however, it may lead to high mortality rates, especially in the immunocompromised hosts and patients with liver cirrhosis. Nosocomial Aeromonas bacteremia is not uncommon in these populations. Broad-spectrum cephalosporins, piperacillin-tazobactam, fluoroquinolones, and carbapenems remain as effective antimicrobial agents for therapy of Aeromonas bacteremia. [ABSTRACT FROM AUTHOR]

Mortality due to K. pneumoniae bacteremia is on rise, particularly in regions with high rates of carbapenem and colistin resistance. We aimed to define risk factors for colistin resistance and its impact on mortality. Patients diagnosed with "carbapenem-resistant K. pneumoniae (CRKp)" bacteremia between 2014 and 2018 were divided into two groups as "colistin susceptible (ColS)" and "colistin resistant (ColR)" based on broth microdilution method. Retrospective case-control study was conducted to compare characteristics and outcomes. Multiple logistic regression model was used to define independent risk factors for acquired colistin resistance and Cox proportional hazard model for 28-day mortality. A total of 82 patients (39 ColS and 43 ColR) were included. Mean age was 61.5 years, and 50 (61%) were male. Colistin resistance was significantly increased with duration of hospital stay (p = 0.007) and prior colistin use (p = 0.007). Overall, the 28-day mortality rate was 66%. Age (p = 0.014) and colistin resistance significantly increased 28-day (p = 0.009) mortality. Microbiological response to treatment within 7 days favors survival. PFGE analysis revealed an outbreak with K. pneumoniae ST78 and ST45 clones. Patients treated with combined antimicrobials had significantly lower 28-day mortality (p = 0.045) in comparison to monotherapy. However, types of combinations did not show significant superiority on each other. Colistin resistance increases 28-day mortality in CRKp bacteremia. Although combined regimens are more effective than monotherapy, existing antibacterial combinations have no apparent superiority to each other. New treatment options are pivotal.

Introduction: The aim of this was to describe the predictors of mortality related to COVID-19 infection and to evaluate the association between overweight, obesity, and clinical outcomes of COVID-19. Methods: We included the patients >18 years of age, with at least one positive SARS-CoV-2 reverse transcriptase-polymerase chain reaction. Patients were grouped according to body mass index values as normal weight <25 kg/m2 (Group A), overweight from 25 to <30 kg/m2 (Group B), Class I obesity 30 to <35 kg/m2 (Group C), and ≥35 kg/m2 (Group D). Mortality, clinical outcomes, laboratory parameters, and comorbidities were compared among 4 groups. Results: There was no significant difference among study groups in terms of mortality. Noninvasive mechanical ventilation requirement was higher in group B and D than group A, while it was higher in Group D than Group C (Group B vs. Group A [p = 0.017], Group D vs. Group A [p = 0.001], and Group D vs. Group C [p = 0.016]). Lung involvement was less common in Group A, and presence of hypoxia was more common in Group D (Group B vs. Group A [p = 0.025], Group D vs. Group A [p < 0.001], Group D vs. Group B [p = 0.006], and Group D vs. Group C [p = 0.014]). The hospitalization rate was lower in Group A than in the other groups; in addition, patients in Group D have the highest rate of hospitalization (Group B vs. Group A [p < 0.001], Group C vs. Group A [p < 0.001], Group D vs. Group A [p < 0.001], Group D vs. Group B [p < 0.001], and Group D vs. Group C [p = 0.010]). Conclusion: COVID-19 patients with overweight and obesity presented with more severe clinical findings. Health-care providers should take into account that people living with overweight and obesity are at higher risk for COVID-19 and its complications. [ABSTRACT FROM AUTHOR]

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 SpO2 < 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 × per capita gross domestic product—GDP) and USD 25.797 (3 × 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 SpO2 < 94% who require oxygen support.

Objective: To assess antibody response to inactivated COVID-19 vaccine in patients with immune-mediated diseases (IMD) among hospital workers and people aged 65 and older. Methods: In this cross-sectional study, we studied 82 hospital workers with IMD (mean age: 42.2 ± 10.0 years) and 300 (mean age: 41.7 ± 9.9 years) controls. Among + 65 aged population, we studied 22 (mean age: 71.4 ± 4.5 years) patients and 47 controls (mean age: 70.9 ± 4.8 years). All study subjects had a negative history for COVID-19. Sera were obtained after at least 21 days following the second vaccination. Anti-spike IgG antibody titers were measured quantitatively using a commercially available immunoassay method. Results: Patients with IMD were significantly less likely to have detectable antibodies than healthy controls both among the hospital workers (92.7% vs 99.7%, p < 0.001) and elderly population (77.3% vs 97.9%, p = 0.011). Among patients with IMD, those using immunosuppressive or immune-modulating drugs (64/75, 85.3%) were significantly less likely to have detectable antibodies compared to those off treatment (29/29, 100%) (p = 0.029). Additionally, a negative association between age and the antibody titer categories among patients (r = − 0.352; p < 0.001) and controls (r = − 0.258; p < 0.001) were demonstrated. Conclusions: Among hospital workers, the vast majority of patients with IMD and immunocompetent controls developed a significant humoral response following the administration of the second dose of inactivated COVID-19 vaccine. This was also true for the elderly population, albeit with lower antibody titers. Immunosuppressive use, particularly rituximab significantly reduced antibody titers. Antibody titers were significantly lower among those aged ≥ 60 years both in patient and control populations. Whether these individuals should get a booster dose warrants further studies.

Summary: Aims: We aimed to determine the contribution of quantitative HBsAg in differentiating chronic infections from chronic hepatitis in HBeAg negative patients with HBV DNA 2000–20,000 IU/ml. Material and methods: A total of 79 untreated HBeAg negative patients were included. Patients were divided into 3 groups based on HBV DNA levels: group 1 (HBV DNA ≤ 2000 IU/ml), group 2 (HBV DNA: 2000–20,000 IU/ml) and group 3 (HBV DNA > 20,000 IU/ml). We collected serum from all patients for quantitative HBsAg analysis. We compared serum quantitative HBsAg levels with biochemical parameters, HBV DNA and liver biopsy results. Results: In this study 46 patients were female and the mean age was 42 years. Serum quantitative HBsAg levels were found to be significantly lower in chronic infections compared with chronic hepatitis. There was a positive correlation between quantitative HBsAg and HBV DNA, ALT (alanine aminotransferase), HAI score (histological activity index), fibrosis score and disease stage. The cut-off level of quantitative HBsAg was determined as 4425 IU/ml to differentiate chronic infection from chronic hepatitis. With the test specificity of 95%, we found quantitative HBsAg cut-off values 1026 IU/ml and 20,346 IU/ml for the diagnosis of chronic infection and chronic hepatitis, respectively. Conclusion: Our study suggests that the quantitative HBsAg ≤ 1000 IU/ml limit value might be used for the diagnosis of chronic infection not only in HBV DNA ≤ 2000 IU/ml but also in patients with HBV DNA between 2000–20,000 IU/ml. In addition, antiviral treatment could be considered in patients with quantitative HBsAg > 20,000 IU/ml and HBV DNA > 2000 IU/ml without further examinations such as liver biopsy.

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 < 0.001). On the other hand, hospital workers were significantly more willing (yes: 52.5%, no: 20.9% and unsure: 26.6%) (p < 0.001). Main concerns were probable side effects, unknown scientific results and having no trust. Being male, older age, working in a hospital, not having contracted COVID-19 and high scores on CAS were found to be independently associated with willingness. Conclusions: The low rate of vaccine acceptance among patients with RD, as well as general population sampling is worrying. Healthcare policies should aim to implement communication, promote confidence and increase demand for COVID-19 vaccine. [ABSTRACT FROM AUTHOR]

Summary: Aims: We aimed to determine the proportion of vancomycin-resistant enterococci (VRE) colonized patients among all inpatients who later developed VRE bacteremia during hospital stay and to identify the risk factors for VRE bacteremia at a tertiary hospital. Material and methods: Patients with positive rectal screening or any clinically significant positive culture results for VRE were included in 1‑year follow-up. Colonization with VRE was defined as a positive culture (rectal, stool, urinary) for VRE without infection and VRE bacteremia was defined as positive blood culture if the signs and symptoms were compatible with infection. To determine the risk factors for VRE bacteremia among VRE colonized patients, a retrospective case control study was performed. The two groups were compared in terms of variables previously defined as risk factors in the literature. Results: Of 947 positive samples, 17 VRE bacteremia were included in the analysis. Cephalosporin use for more than 3 days within 3 months was a significant risk factor for bacteremia (p = 0.008). Prior use of carbapenems was found to be statistically significant for bacteremia (p = 0.007). In multivariate analyses the use of carbapenems and cephalosporins was an independent risk factor for developing bacteremia among VRE colonizers (odds ratio, OR, 6.67; 95% confidence interval, CI, 1.30–34; p = 0.022 and OR 4.32, 95% CI 1.23–15; p = 0.022, respectively). Conclusion: A VRE colonization in patients receiving broad-spectrum beta-lactam antibiotics including carbapenems and cephalosporins may result in bacteremia. It is possible to keep mortality at very low levels in VRE bacteremia with effective infection control measures, rapid infectious diseases consultation and rational antimicrobial treatment based on current epidemiological data.

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.

Background: One-fifth of COVID-19 patients are seriously and critically ill cases and have a worse prognosis than non-severe cases. Although there is no specific treatment available for COVID-19, early recognition and supportive treatment may reduce the mortality. The aim of this study is to develop a functional nomogram that can be used by clinicians to estimate the risk of in-hospital mortality in patients hospitalized and treated for COVID-19 disease, and to compare the accuracy of model predictions with previous nomograms.Methods: This retrospective study enrolled 709 patients who were over 18 years old and received inpatient treatment for COVID-19 disease. Multivariable Logistic Regression analysis was performed to assess the possible predictors of a fatal outcome. A nomogram was developed with the possible predictors and total point were calculated.Results: Of the 709 patients treated for COVID-19, 75 (11%) died and 634 survived. The elder age, certain comorbidities (cancer, heart failure, chronic renal failure), dyspnea, lower levels of oxygen saturation and hematocrit, higher levels of C-reactive protein, aspartate aminotransferase and ferritin were independent risk factors for mortality. The prediction ability of total points was excellent (Area Under Curve = 0.922).Conclusions: The nomogram developed in this study can be used by clinicians as a practical and effective tool in mortality risk estimation. So that with early diagnosis and intervention mortality in COVID-19 patients may be reduced. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Hepatitis delta virus (HDV) infection causes the most severe form of viral hepatitis. PEG‐interferon alpha‐2a (PEG‐IFNα‐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‐IFNα‐2a plus adefovir dipivoxil (ADV) (Group I), PEG‐IFNα‐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‐IFNα‐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‐IFNα‐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‐IFNα‐2a treatment leads to improved clinical long‐term outcome. [ABSTRACT FROM AUTHOR]

Background: Recent data have suggested the presence of a reciprocal relationship between COVID-19 and kidney function. To date, most studies have focused on the effect of COVID-19 on kidney function, whereas data regarding kidney function on the COVID-19 prognosis is scarce. Therefore, in this study, we aimed to investigate the association between eGFR on admission and the mortality rate of COVID-19. Methods: We recruited 336 adult consecutive patients (male: 57.1%, mean age: 55.0±16.0 years) that were hospitalized with the diagnosis of COVID-19 in a tertiary care university hospital. Data were collected from the electronic health records of the hospital. On admission, eGFR was calculated using the CKD-EPI formula. Acute kidney injury was defined according to the KDIGO criteria. Binary logistic regression and Cox regression analyses were used to assess the relationship between eGFR on admission and in-hospital mortality of COVID-19. Results: Baseline eGFR was under 60 mL/min/1.73m2 in 61 patients (18.2%). Acute kidney injury occurred in 29.2% of the patients. In-hospital mortality rate was calculated as 12.8%. Age-adjusted and multivariate logistic regression analysis (p: 0.005, odds ratio: 0.974, CI: 0.956–0.992) showed that baseline eGFR was independently associated with mortality. Additionally, age-adjusted Cox regression analysis revealed a higher mortality rate in patients with an eGFR under 60 mL/min/1.73m2. Conclusions: On admission eGFR seems to be a prognostic marker for mortality in patients with COVID-19. We recommend that eGFR be measured in all patients on admission and used as an additional tool for risk stratification. Close follow-up should be warranted in patients with a reduced eGFR.

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 R2 =.14 F(15–389) = 4.46 P =.000), and 10% of the disclosure were explained by the variables (Adjusted R2 =.10 F(15–389) = 4.29 P =.000). The discrimination dimension had a strong positive relationship with the knowledge of HIV transmission modes. In our view, if physicians and nurses receive adequate and comprehensive training on HIV including stigma, the formations of stigma may be prevented and may not develop. [ABSTRACT FROM AUTHOR]

Antimicrobial stewardship is of major importance in patients with febrile neutropenia (FN). In this study, we aimed to investigate the trends in resistance and the relationship with mortality rates in patients with FN. The single-center surveillance data of inpatients with FN and diagnosed as microbiologically confirmed bloodstream infections (BSIs) between 2006 and 2016 were reviewed retrospectively. A total of 950 episodes in 552 patients with BSIs were analyzed. Of whom, 55.9% were male, the median age was 43 years, and 35.6% had acute myeloid leukemia. In total, 1016 microorganisms were isolated from blood cultures. Gram-negatives accounted for 42.4% (n = 403) of the episodes. Among Gram-negatives, Enterobacteriaceae accounted for 346 (86%) (E. coli, n = 197; 34% extended-spectrum β-lactamases (ESBL) producers, and Klebsiella spp., n = 120; 48.3% ESBL producers). Also, 24 (20.0%) of Klebsiella spp. had carbapenemase activity. There were 6 (5.0%) colistin-resistant Klebsiella spp. Thirteen (26.5%) of Pseudomonas spp. and 17 (60.7%) of Acinetobacter spp. had carbapenemase activity. There were 2 (5.6%) colistin-resistant Acinetobacter spp. The 30-day mortality rates were 12.0%, 21.5%, 34.6%, and 29.0% in BSIs due to Gram-positive, Gram-negative bacterial, fungal, and polymicrobial etiology respectively (p = 0.001). BSIs with ESBL-producing (p = 0.001) isolates, carbapenem (p < 0.001), and colistin-resistant isolates (p < 0.001) were associated with increased mortality risk. The tremendous rise in resistance rates among Gram-negatives is dreadfully related to increasing mortality and leads to sharp shifts toward extreme restrictions of unnecessary antibiotic uses. Antimicrobial stewardship in patients with FN requires vigilance and tailoring of treatment upon local surveillance data. [ABSTRACT FROM AUTHOR]

COVID-19 infection has a heterogenous disease course; it may be asymptomatic or causes only mild symptoms in the majority of the cases, while immunologic complications such as macrophage activation syndrome also known as secondary hemophagocytic lymphohistiocytosis, resulting in cytokine storm syndrome and acute respiratory distress syndrome, may also occur in some patients. According to current literature, impairment of SARS-CoV-2 clearance due to genetic and viral features, lower levels of interferons, increased neutrophil extracellular traps, and increased pyroptosis and probable other unknown mechanisms create a background for severe disease course complicated by macrophage activation syndrome and cytokine storm. Various genetic mutations may also constitute a risk factor for severe disease course and occurrence of cytokine storm in COVID-19. Once, immunologic complications like cytokine storm occur, anti-viral treatment alone is not enough and should be combined with appropriate anti-inflammatory treatment. Anti-rheumatic drugs, which are tried for managing immunologic complications of COVID-19 infection, will also be discussed including chloroquine, hydroxychloroquine, JAK inhibitors, IL-6 inhibitors, IL-1 inhibitors, anti-TNF-α agents, corticosteroids, intravenous immunoglobulin (IVIG), and colchicine. Early recognition and appropriate treatment of immunologic complications will decrease the morbidity and mortality in COVID-19 infection, which requires the collaboration of infectious disease, lung, and intensive care unit specialists with other experts such as immunologists, rheumatologists, and hematologists.
