Correlation between depression and adherence to respiratory function exercise in elderly frail patients with tuberculosis: A cross-sectional survey.

We investigated the current state of frailty in elderly patients with tuberculosis and analyzed the factors that influence it. Using a convenience sampling method, 120 elderly patients with tuberculosis were selected from the Department of Infectious Diseases at Lishui Hospital of Traditional Chinese Medicine in Zhejiang Province. A cross-sectional survey was conducted using general demographic questionnaires, the FRAIL (fatigue, resistance, aerobic capacity, illnesses, and loss of weight) screening scale, the self-rating depression scale (SDS), and a questionnaire on respiratory function exercise adherence. The influencing factors for depression were analyzed using logistic regression. The average depression score of the 120 elderly patients with frailty and tuberculosis was 54.88 ± 5.61, indicating a mild level of depression. The correlation between this score and respiratory function exercise adherence was negative. According to a logistic regression analysis, marital status and payment methods were influencing factors for depression in these elderly patients with frailty and tuberculosis. There is a need to increase respiratory function exercise adherence among elderly patients with frailty and tuberculosis who have a high incidence of depression. Medical staff should assess adverse emotions in patients and their adherence to respiratory function exercises on a periodic basis.

Epidemio-clinical aspects and neuro-meningeal tuberculosis prognosis in Batna

Neuromeningeal tuberculosis is rare, affecting around 1-2% of all tuberculosis cases and 5% of extra pulmonary tuberculosis cases. Our aim is to describe the epidemio-clinical, prognostic and evolutionary aspects of neuromeningeal tuberculosis. Materials and methods: To determine the spectrum of etiological agents of HIV-negative encephalitis and meningoencephalitis in Batna, we conducted a prospective study using an expanded testing approach. Patients were recruited from three departments (intensive care unit, infectious diseases department, pediatrics) during the period from April 1, 2012, to August 31, 2015. Data were collected according to the FLIPS case definition with a standardized form. We sought to identify etiological pathogens following a standardized procedure and to describe the epidemiological, clinical and biological features and outcomes associated with different causes. Results: A total of 141 patients with infectious encephalitis and meningoencephalitis were included in the study. Bacterial etiology was determined in 65/141 (46.1%) of whom 30 cases (21.3%) were of tuberculous origin; 21 confirmed and/or probable cases 9 possible cases with high clinical, epidemiological and radiological probability. The median age was 30.5 (0-83), predominantly female 12/18, 23.3% comorbidity with a frequency of motor deficits (86.7%) and psychiatric disorders (26.8%), respiratory involvement was present in 60% of cases, pleocytosis was present in 22/25 (73.4%). hyperalbuminorachy in 66. 7%, and hypoglycorachia in (46.7%). Anti-tuberculosis treatment was instituted in 90% of cases,17.6% were initially admitted to an intensive care unit, and the median length of hospital stay was 38.5 (1-146). death was identified in 46.6%, with 10% having sequelae. Conclusion: In our study, in addition to viruses, bacteria (especially intracellular) can be responsible for encephalitis and meningoencephalitis, in varying proportions. The most frequent and leading form of bacterial meningoencephalitis in adults is tuberculosis, the prognosis of which depends on early treatment.

The seroprevalence of COVID-19 among people living with HIV in Morocco

The association of COVID-19 and HIV infection would seem deadly in terms of prognosis and the possibilities of viral clearance given the immunodeficiency. However, a lower seroprevalence has been reported in some studies compared to that found in the non-HIV population. The objective of this study is to determine the seroprevalence of COVID-19 among people living with HIV (PLHIV) in Morocco. This is a prospective study carried out in the infectious diseases department of the Ibn Rochd University Hospital in Casablanca. We included PLHIV who consulted the Infectious Diseases Day-Hospital service between January 18, 2021 and March 10, 2021. After informed consent, patients completed a survey and had blood drawn for SARS-CoV-2 antibody testing. The determination of IgG antibodies against SARS-CoV-2 in blood was carried out using chemiluminescence microparticle immunoassay technology. We included 418 PLHIV in the study, most patients were male (50.24%), the average age was 40 years, 90.2% of patients were on antiretroviral treatment, 56.7% had a viral load <20 copies/ml, and 47.37% had a CD4 count greater than 500 cells/μL. The IgG test was positive in 53 patients, representing a seroprevalence of 12.68%. None of the patients had clinical signs. Seroprevalence was higher in female patients (58.49%), aged between 30 and 40 years (41.51%), in patients with a negative viral load (64.15%) and a CD4 count greater than 500 cells/mm3 (49.6%). Our study showed that the seroprevalence of COVID-19 was higher among PLHIV compared to people without HIV infection. All the patients had asymptomatic forms which pushes us to evoke a theory, to demonstrate, of the action of antiretrovirals against SARS-CoV-2.

Covid-19 in HIV-infected patients: A report of 14 cases experience of the infectious diseases department of the University Hospital Mohamed VI Marrakech - Faculty of Medicine and Pharmacy Marrakech

Objective: Evaluation of clinical, biological, radiological characteristics, therapeutic management and outcome in patients with HIV / SARS-COV-2 co-infection. Materials and Methods: Descriptive retrospective study of 14 files of patients with HIV / SARS-COV-2 co-infection confirmed by SARS-COV-2 PCR between April 2020 and May 2022 in the infectious diseases department of the University Hospital Mohamed VI Marrakech Results: 14 patients were included, with a sex ratio M/F: 2.5. The mean age of our patients was 40.7 years. The clinical symptoms presented by our patients were: asthenia (71%); febrile pneumonia (64.20%); anosmia (46.6%); diarrhea (28.5%); and lower limb thrombophlebitis (7.14%). The HIV status was as follows: 9 new cases (64.2%), while HIV was already present in 5 patients (35.8%). On the radiological level, 10 patients had moderate damage (72%), 3 patients had mild damage (21%), while 1 patient had severe damage (7%). Our patients' treatment changed during the study period; in particular, one group of patients was treated with the national covid-19 therapeutic protocol, while others received molnupiravir. The outcome was overall good, with a clear clinical and biological improvement; and only 4 patients died. Conclusion: The predisposition to SARS-COV2 infection as well as the clinical presentation and evolution of Covid 19 in PLHIV do not differ from the general population.

Characterization of acute-on-chronic liver diseases: A multicenter prospective cohort study.

Acute-on-chronic liver disease (AoCLD) accounts for the majority of patients hospitalized in the Department of Hepatology or Infectious Diseases. To explore the characterization of AoCLD to provide theoretical guidance for the accurate diagnosis and prognosis of AoCLD. Patients with AoCLD from the Chinese Acute-on-Chronic Liver Failure (ACLF) study cohort were included in this study. The clinical characteristics and outcomes, and the 90-d survival rate associated with each clinical type of AoCLD were analyzed, using the Kaplan-Meier method and the log-rank test. A total of 3375 patients with AoCLD were enrolled, including 1679 (49.7%) patients with liver cirrhosis acute decompensation (LC-AD), 850 (25.2%) patients with ACLF, 577 (17.1%) patients with chronic hepatitis acute exacerbation (CHAE), and 269 (8.0%) patients with liver cirrhosis active phase (LC-A). The most common cause of chronic liver disease (CLD) was HBV infection (71.4%). The most common precipitants of AoCLD was bacterial infection (22.8%). The 90-d mortality rates of each clinical subtype of AoCLD were 43.4% (232/535) for type-C ACLF, 36.0% (36/100) for type-B ACLF, 27.0% (58/215) for type-A ACLF, 9.0% (151/1679) for LC-AD, 3.0% (8/269) for LC-A, and 1.2% (7/577) for CHAE. HBV infection is the main cause of CLD, and bacterial infection is the main precipitant of AoCLD. The most common clinical type of AoCLD is LC-AD. Early diagnosis and timely intervention are needed to reduce the mortality of patients with LC-AD or ACLF.

Real-life impact on antimicrobial prescription of Syndromic Molecular Testing in adults hospitalized in infectious disease departments. Respiratory Syndromic Molecular Testing panel: Is it worth it?

BackgroundWhile sensitive molecular diagnostic tests enable accurate and rapid diagnosis of many respiratory viruses, their impact on antibiotic management remains uncertain.Our study aimed to evaluate the impact of respiratory syndromic molecular testing panel in real-life clinical practice. MethodRetrospective descriptive study involving consecutive hospitalized patients in an infectious disease department who had been prescribed a respiratory syndromic molecular testing panel on nasopharyngeal swab samples (FilmArray Respiratory Panel 2 plus) during hospitalization from October 1st, 2021, to February 28th, 2023. ResultsAll in all, 94 out of 210 screened patients were included in the study. Syndromic molecular testing results influenced antibiotic treatment in seven cases: discontinuation in four cases (three virus identifications), changes in two (Mycoplasma pneumoniae positive cases), and initiation in two (negative viral PCRs and one positive bacterial culture). ConclusionIn our study, respiratory syndromic molecular testing had low impact on antibiotic modification.

Transforming health care: Investigating Influenzer, a novel telemedicine-supported early discharge program for patients with lower respiratory tract infection: A non-randomized feasibility study.

The COVID-19 pandemic has posed unprecedented challenges to healthcare systems globally, necessitating innovative care models like hospital-at-home and virtual care programs. The Influenzer telemedicine program aims to deliver hospital-led monitoring and treatment to patients at home. Integrating telemedicine technology with domestic visits provides an alternative to traditional hospitalization, with the aim of easing the burden on healthcare facilities without compromising patient safety. To evaluate the effectiveness of the Influenzer program, a randomized controlled trial is proposed. This study aimed to assess the feasibility of the proposed clinical trial design. A non-randomized feasibility study was conducted at the Department of Pulmonary and Infectious Diseases at Nordsjaellands Hospital offering a telemedicine-supported early discharge program to patients with lower respiratory tract infections, including COVID-19. The feasibility of trial procedures, including recruitment, adherence, and retention, was analyzed. Also, participants' characteristics and trajectory during the intervention, including telemedicine and domestic services, were assessed. Nineteen patients were enrolled from June 2022 to April 2023 and treated at home. Forty patients were not enrolled as 15 (25%) were non-eligible according to study protocol, 15 (25%) refused to participate and 10 (17%) had not been approached. Subjects treated at home had comparable clinical outcomes to those treated in the acute hospital, no major safety incidences occurred and patients were highly satisfied. Participants demonstrated 99% adherence to planned daily monitoring activities. In total, 63% completed all survey assessments at least partially including baseline, at discharge, and 3 months post-discharge, while 89% participated in a follow-up interview. No participants withdrew their consent. The feasibility study documented that the Influenzer home-hospital program was feasible and well accepted in a Scandinavian setting in terms of no withdrawals and excellent participant adherence to the planned daily monitoring activities. Challenges in the organizational structures including patient recruitment and data collection required resolution prior to our randomized clinical trial. Insights from this feasibility study have led to the improved design of the final Influenzer program evaluation trial. ClinicalTrials.gov, NCT05087082. Registered on 18 August 2021.

Tenascin-C in patients with central nervous system infections

BackgroundThe extracellular matrix protein tenascin-C has been discovered to be an important regulator of the response to tissue injury and repair in cerebrovascular diseases. This study investigated if tenascin-C is released in response to infections in the central nervous system (CNS). MethodsTenascin-C concentration in the cerebrospinal fluid (CSF) was measured in patients, (>18 years) with and without CNS infections, admitted to a department of infectious diseases in Denmark. CSF tenascin-C was measured on the Meso-scale platform. Results174 patients were included of which 140 were diagnosed with a CNS infection and 34 where this was ruled out (control group). Median CSF tenascin-C levels were significantly higher among patients with bacterial meningitis (147 pg/mL), viral meningitis (33 mg/mL), viral encephalitis (39 pg/mL) and Lyme neuroborreliosis (45 pg/mL) when compared to controls (21 pg/mL). Correlations between tenascin-C and CSF markers of inflammation and age were only moderate. ConclusionLevels of CSF tenascin-C are higher among patients with bacterial and viral neuroinfections, already on admission, but exhibit only a modest correlation with baseline indices of neuroinflammation. CSF tenascin-C is highest among patients with bacterial meningitis compared to the other CNS infections. Patients with unfavorable outcomes presented with higher median CSF tenascin-C than their counterparts.

Acute hepatitis B outbreak in a nursing home for the disabled in Türkiye.

Although hepatitis B is vaccine-preventable, it remains a significant health problem. To the best of our knowledge, this is the first hepatitis B outbreak report from Türkiye. To investigate the cause of hepatitis B outbreak in a nursing home for the disabled and make recommendations for prevention. An outbreak of acute hepatitis B was declared in a nursing home for the disabled following the admission of 3 patients from the home in a hospital. Collaborative response was initiated with the Provincial Health Directorate through the Public Health Infectious Diseases Department. We began tracking the infection and monitoring active cases. Audits and controls were carried out to determine the source, establish protection and control measures, and prevent further transmission. Six of the 65 nursing home residents were diagnosed with acute hepatitis B. Four of them had diabetes and their blood glucose levels were monitored for at least 12 months. Two of the patients had received dental treatment in the last 6 months. The frequency of both variables, which may be an indication of the transmission route, was statistically significantly greater in the acute hepatitis B group. All the patients who could be sequenced were identified as genotype D. While 3 patients recovered fully, 2 were diagnosed with chronic hepatitis B and one died due to fulminant hepatitis. Standard routine immunization should be implemented as a preventive measure for acute hepatitis B. Frequent supervision and training on hygiene practices and safety precautions should be conducted for care staff working in collective residential facilities.

Tocilizumab in the treatment of hyperferritinemic syndrome and capillary leak syndrome secondary to rheumatoid arthritis: Case report and literature review.

Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease, which is mainly characterized by joint swelling, pressure pain and joint destruction. Some patients may suffer from a variety of serious complications, which require prompt diagnosis and treatment. Otherwise, the patient condition may deteriorate rapidly, leading to premature death. We reported a case of RA combined with hyperferritinemic syndrome and capillary leak syndrome (CLS) that was successfully treated with tocilizumab (TCZ), with the aim of improving diagnostic ideas for clinicians and consequently improving the diagnosis and treatment of the hyperferritinemic syndrome and CLS. A 55-year-old female patient was admitted to the Department of Infectious Diseases of our hospital due to "recurrent fever for more than 1 month and aggravation for 3 days." The patient was diagnosed with fever of unknown origin (lung infection?) and received anti-infective therapy with large encirclement of anti-bacterial, antifungal and empirical anti-tuberculosis successively during hospitalization in the Department of Infectious Diseases. Yet her condition continues to progress. The patient was eventually diagnosed with RA combined with hyperferritinemic syndrome and CLS. Then she received glucocorticoids (GC) (160 mg qd) combined with intravenous immunoglobulin (IVIG, 20 g/d, for 3 days). We considered that the patient also had an overwhelming proinflammatory cytokine storm, so she received a strong anti-inflammatory treatment with TCZ (400 mg qm). The patient symptoms and follow-up chest CT showed significant improvement following treatment. TCZ has good efficacy in the treatment of RA combined with hyperferritinemic syndrome and CLS and is expected to be a promising treatment.

Launch of Board Certification in Pediatric Infectious Diseases in Japan.

To cultivate specialists in pediatric infectious diseases (ID) in Japan, the Japanese Society for Pediatric Infectious Diseases initiated board certification for pediatric ID in 2017. Previously, in 2014, we had formed a committee for board certification in pediatric ID and discussed the fundamentals of the board certification system, including the goals, requirements for designated training institutions, provisional certification of pediatric ID specialists and eligibility for and content of the board certification examination. After approval from 31 programs, the pediatric ID programs started in 2017 with 8 fellows in 7 programs. The first 6 graduates received board certification in 2020. To date, 61 pediatricians have been board certified as pediatric ID specialists. In parallel, we introduced board certification for pediatricians who work mainly in primary care settings and have a special interest in pediatric ID. This system has certified 338 pediatricians. During and after the development of the programs, we achieved substantial progress in highlighting the pivotal role of pediatric ID specialists, including the establishment and maintenance of antimicrobial stewardship programs, pediatric ID consultations and introduction of viral diagnosis by polymerase chain reaction at institutions. However, several issues need to be addressed, including the establishment of independent pediatric ID departments in institutions, payment of consultation fees, program site visits, maintenance of certification and cultivation of physician-scientists. These challenges will be the focus of future efforts.

Predictors of Nucleos(t)ide Analogues Discontinuation Relapse: Hepatitis B Virus RNA versus Hepatitis B Surface Antigen.

To compare the predictive value of hepatitis B virus (HBV) RNA and HBsAg quantification upon discontinuation of nucleos(t)ide analogues (NAs) therapy for clinical and virological relapse in chronic hepatitis B (CHB). Observational study. Place and Duration of the Study: Department of Infectious Diseases and Hepatology, The Second Hospital of Shandong University, Jinan, China, from July 2014 to December 2020. CHB patients received single NAs and discontinued treatment following appropriate standards. HBsAg quantification was conducted using the i2000 Chemiluminescent Immunoassay (CLIA) Analyser, while serum HBV RNA quantification was performed using specific RNA target capture and simultaneous amplification and testing. The main observational endpoints included virological relapse and clinical relapse. Eighty-one patients were recruited, with 15 patients achieving HBsAg loss at cessation. Twenty-nine individuals encountered virological relapse, while 13 patients experienced clinical relapse. Thirty-one patients achieved HBsAg <100 IU/ml at NAs cessation, among whom 26 achieved undetectable HBV RNA, while four patients suffered virological relapse (15.4%). Serum HBV RNA emerged as an independent determinant of virological relapse (HR 1.850), clinical relapse (HR 2.020), and HBsAg loss after NAs cessation (HR 0.138). The presence of HBsAg <100 IU/ml at cessation did not serve as a predictor for virological relapse and clinical relapse. Lower HBV RNA levels predict a better off-treatment response. Discontinuation of prolonged NAs therapy appears as a viable and safe choice for patients with undetectable HBV RNA. In comparison to HBV RNA, HBsAg <100 IU/ml at cessation did not show sufficient predictive value for virological relapse and clinical relapse. HBV RNA, Hepatitis B surface antigen, Chronic hepatitis B, Relapse.

Analysis of Aetiological Agents in Infectious Endocarditis in the Central Military Emergency University Hospital "Dr. Carol Davila" Bucharest.

Infective endocarditis (IE) is a pathological condition caused by various microbial agents that can lead to severe complications affecting the heart. Accurate diagnosis is crucial for the effective management of patients with IE. Blood culture is the gold standard for identifying the primary infectious agents, which is a key factor in diagnosing IE using the modified Duke criteria. The main objective of this study was to investigate the distribution of the etiological agents of IE and the most common secondary diagnoses associated with it. A total of 152 patients aged 23-95 years with a diagnosis of IE and proven etiology (through blood cultures or serological tests) were included in this study. The most common etiological agent identified through blood tests was Enterococcus faecalis, which was detected in 39 patients (23.5%). Staphylococcus aureus was the second most common agent and was identified in 33 patients (19.9%), followed by Staphylococcus epidermidis, which was identified in 12 patients (13.1%). Nine patients (5.8%) had high levels of anti-Coxiella burnetti IgG phase I and II antibodies. IE is a leading cause of death in the Department of Infectious Diseases. Early and accurate diagnosis, along with interdisciplinary treatment, can significantly increase the chances of patient survival. Currently, Enterococcus faecalis and Staphylococcus aureus are the dominant etiological agents of IE, highlighting the need to revise protocols for prophylaxis, diagnosis, and initial treatment of this condition.

Comparison of 2 Days versus 5 Days of Octreotide after Endoscopic Therapy in Preventing Early Esophageal Varices Rebleed: A Randomized Controlled Study

In esophageal varices bleeding, following the initial endoscopic hemostasis, it is recommended to administer vasoactive medications for a period of 2-5 days in order to avoid early rebleeding. Octreotide is the preferred vasoactive medication for treating variceal bleeding due to its favorable safety profile. This study aimed to assess the effectiveness of a 2-day octreotide infusion against a 5-day octreotide infusion following endoscopic intervention in avoiding early rebleeding of esophageal varices in individuals with cirrhosis. This study was a prospective, parallel, randomised controlled experiment conducted on a cohort of 184 subjects who were recruited from the endoscopy unit of the Tropical Medicine and Infectious Diseases Department at Tanta University Hospital in Egypt. The five days rate of rebleeding was 16.85% in the 2-days group against 15.91% in the 5- days group without significant difference (P= 0.865). In cirrhotic individuals with bleeding esophageal varices, a 2-day regimen of octreotide is equally efficacious as a 5-day regimen in avoiding rebleeding over a 5-day period, following successful control of bleeding with endoscopic intervention.

ObjectivesContinuous curriculum improvements reveal the dedication of policy-makers to raising the quality of education and student learning. This study aims to report the impact of curriculum changes to the three-month pediatric course curriculum at Shahid Beheshti University of Medical Sciences (SBMU) on the satisfaction levels of medical students.MethodsOne hundred eighteen 4th-5th years medical students, who had completed their pediatric clinical rotation in SBMU-affiliated teaching hospitals including Mofid Children Hospital, Loghman Hakim Hospital, Shohada-e-Tajrish Hospital, and Imam Hossein Hospital from January to December 2022 were included in this cross-sectional study. After obtaining informed consent, a questionnaire was sent out to all participants, that included 27 statements about the impact of the modified curriculum on their satisfaction with their learning and performance. SPSS version 22 was used to analyze the data.ResultsThe level of satisfaction of trainees from attending clinics was 82-56%, prior introduction to the course was about 82%, and attending general hospitals (all hospitals except Mofid Children hospital, which is the only children hospital affiliated to SBMU) was 82-97%. The quality of patients-based learning was reported in terms of attendance at morning report sessions which was 92.3%, attendance at ward rounds, which was 71.8%, and attendance at clinics, which was 62.4%. The satisfaction rate from the senior attending mentor was 96.5%. The satisfaction rate of the pathology course was 67.2%, and the radiology was 82.4%. The satisfaction level of medical students from the infectious disease department was 70% and the gastroenterology department was 83.8%. The level of satisfaction with the implementation of the twelve-week program was 68.7%, with the expressiveness and usability of the presentation of materials was 53.9%, with the compatibility of the exams with the presented materials was 92%, and withholding weekly exams was 86.8%. The satisfaction rate of using the materials presented in the final exam in the digestive department and the infectious department was 85% and 68%, respectively. The overall satisfaction rate of the training course was 76.66%.ConclusionThe results provide vital insights for improving medical education. According to this study, medical student satisfaction with the pediatric curriculum after its recent revisions was in a satisfactory range. Attendance at clinics, information sharing, patient-based learning, practical training, attending mentorship, curriculum clarity, and alignment with student expectations all contributed to participants' high levels of satisfaction.

Opportunistic Infections and Impact on Morbidity and Mortality During HIV in the Infectious Diseases Department at Point G Hospital in Bamako

Aim: In the contexts of free treatment and the "test and treat" strategy, we conducted this study whose objectives are to identify the main opportunistic infections (OIs) and their impact on the future of HIV-infected patients. Patients and methods: This was a cross-sectional retrospective study of variables from the medical records of HIV-infected person hospitalized between January 1, 2015 and December 31, 2021. Results: Out of 2631 hospitalized patients, 1237 were HIV-positive (47%), 54,4% had OIs. The sex ratio was 0.86 and the mean age was 38.9 ± 10.37 years. The main opportunistic infections are candidiasis (39.32%), tuberculosis (25.25%) and cerebral toxoplasmosis (14.57%). The lethality was 43.7% (540/1237). Death was statistically related to opportunistic infections: tuberculosis (p &lt;0.0001), toxoplasmosis (p = 0.004), candidiasis (p &lt;0.0001) and prurigo (p = 0.04) and stage 4 of WHO (p &lt;0.0001) and CD4 ≤ 200 / ml. Conclusion: Death was statistically related to tuberculosis, toxoplasmosis, and stage 4 of WHO deep immunosuppression and CD4 ≤ 200/ml as reported by candidiasis and prurigo. Screening and early management of opportunistic infections and even HIV will help lower mortality

Is there an interest in systematic serum screening for aspergillosis in COVID-19 patients in a medical ward?

PurposeWe evaluated the interest of systematic screening of serum fungal markers in patients hospitalized in a medical ward. MethodsWe retrospectively analyzed all patients hospitalized in our infectious disease department from October 1st to October 31st, 2020 for COVID-19 without prior ICU admission, and for whom systematic screening of serum fungal markers was performed. ResultsThirty patients were included. The majority of patients received corticosteroids (96.7%). The galactomannan antigen assay was positive for 1/30 patients at D0, and 0/24, 0/16, 0/13 and 0/2 at D4, D7, D10 and D14 respectively. 1,3-ß-D-glucan was positive for 0/30, 1/24, 1/12, 0/12, 0/2 at D0, D4, D7, D10 and D14 respectively. No Aspergillus fumigatus PCR was positive. No cases of aspergillosis were retained. ConclusionOur study does not support the interest of systematic screening of fungal markers in immunocompetent patients with COVID-19 in a conventional unit.

Effect of HBV DNA load on the safety and prognosis of systematic therapy in advanced hepatocellular carcinoma

Objective: To study the effect of hepatitis B virus (HBV) infection on the occurrence of liver damage, HBV reactivation (HBVr) and the influence of HBVr on the prognosis of patients with advanced hepatocellular carcinoma (HCC) receiving systemic therapy. Methods: The clinical data of 403 patients with HBV-related HCC at the Department of Infectious Diseases, The Third Affiliated Hospital of Sun Yat-Sen University et al, from July 2018 to December 2020 were collected. The incidence of liver damage and HBVr during systematic therapy, and the influence of HBVr on survival prognosis were analyzed. Results: Of the 403 patients, 89.1% were male (n=359), with a median age of 51 years (51.5±12.1). Before propensity score matching (PSM), the proportion of patients with cirrhosis, TNM and advanced BCLC stage was higher in high HBV-DNA (baseline HBV-DNA>1000 U/ml, n=147) group comparing with the low HBV-DNA (baseline HBV DNA≤1000 u/ml, n=256) group (P<0.05). There was no significant difference in baseline indexes between the two groups after PSM. In 290 patients after PSM, there was no significant difference in the incidence of liver damage and HBVr between high HBV-DNA group and low HBV-DNA group (P>0.05). Survival analysis was performed on 169 patients with survival data, the median overall survival (OS) was found to be 11.49 months (95%CI: 7.77-12.89) and 16.65 months (95%CI: 10.54-21.99, P=0.008) in the high and low HBV-DNA groups, respectively. And median progression-free survival (PFS) was 7.41 months (95%CI: 5.06-8.67) and 10.55 months (95%CI: 6.72-13.54, P=0.038), respectively, with a statistically significant difference. There were no differences in overall survival (OS) and progression-free survival (PFS) between patients with and without HBVr and those with or without liver damage (P>0.05). Conclusions: HBV-DNA levels above 1 000 U/ml before systemic therapy do not increase the risk of liver damage or HBVr during systemic therapy in patients with HBV-related hepatocellular carcinoma, and such patients can safely receive systemic therapy.
