Efficacy and safety of first-line anti-tuberculosis drugs combined with Linezolid for the treatment of pediatric tuberculous meningitis in real-word practice

Objective: To evaluate the efficacy and safety of first-line anti-tuberculosis (TB) drugs combined with linezolid in treatment of children with tuberculous meningitis (TBM). Methods: A retrospective cohort study design was performed. Eight-nine Children diagnosed as TBM during January 1st 2016 and December 31st 2023 in Department of Infectious Disease, Children's Hospital of Chongqing Medical University were enrolled in the study. According to different treatment regimens, children were divided into a group of first-line anti-tuberculous drugs (isoniazid, rifampicin, pyrazinamide, ethambutol (HRZE)) and a group of HRZE and linezolid combination (HRZEL). The efficacy and safety of the 2 regimens were compared and the relationship between linezolid drug concentration and adverse reactions were analyzed. Comparisons between groups were performed using χ2 test and Mann-Whitney U test. Results: The 89 children with TBM included 53 males and 36 females with an onset age of 4.6 (1.4, 9.6) years. There were 27 cases in the HZREL group and 62 cases in the HRZE group. Before treatment, positive rate of interferon-gamma release assays (IGRA) in HRZEL group was lower than that in HRZE group (64% (16/25) vs.92% (55/60), χ2=9.82, P<0.05), but protein level of cerebrospinal fluid (CSF) was higher than that in HRZE group (1.2 (1.0, 2.0) vs.0.8 (0.4,1.4) g/L, Z=0.32, P<0.05). By the end of the intensive phase, there were no significant differences of rates of CSF improvement and etiology negativity between HRZEL group and HRZE group (both P>0.05).The 44 TBM children with high CSF protein (>1 g/L) included 25 males and 19 females with an onset age of 6.7 (3.0, 11.8) years. There were 21 cases in the HZREL group and 23 cases in the HRZE group accordingly. Before treatment, there were no significant differences of positive rate of IGRA test and CSF protein level between the 2 groups (62% (13/21) vs. 87% (20/23), 1.7 (1.1, 2.2) vs. 1.5 (1.2, 1.9) g/L, χ2=3.67, Z=0.23, both P>0.05). There were no significant differences in CSF indicators, etiology negativity or imaging remission between the two groups by the end of intensive phase (all P>0.05). Higher frequencies of granulocytopenia, gastrointestinal symptoms as well as withdrawal or change of drugs were found in HRZEL group when compared to those in HRZE group (44% (12/27) vs. 19% (12/62), 7% (2/27) vs. 0, 33% (9/27) vs. 3% (2/62), χ2=6.01, 4.70, 15.74, all P<0.05). Conclusions: The efficacy of HRZEL regimen is similar to conventional HRZE regimen in children with TBM, but with higher adverse effect. Prudentially evaluating the pros and cons of linezolid in the usage of drug-susceptible TB and carefully monitoring of linezolid associated adverse effects is suggested.

Prosthetic Valve Endocarditis: A Retrospective Cohort Study Conducted at "Dr. Carol Davila" Central Military Emergency University Hospital in Bucharest.

To evaluate patients with prosthetic valves who developed infective endocarditis by comparing treatment outcomes in both early- and late-onset IE episodes following prosthetic valve replacement surgery. This study sought to conduct a comprehensive assessment of the efficacy of these methodologies. The insights derived from this assessment can be utilized to enhance the quality of care for individuals with infective endocarditis who have undergone prosthetic valve replacement surgery. During the period of investigation (January 2017-December 2022), 78 patients diagnosed with infective endocarditis (IE) on a prosthetic valve were admitted to the Infectious Diseases Department of the "Dr. Carol Davila" Central Military Emergency University Hospital in Bucharest. In 28 patients (35.8%), the onset of PVE occurred within 12 months of surgery (early onset), whereas in 50 patients (64.2%), the onset occurred more than 12 months after surgery (late onset). The mortality rate was 35.9% (53.6% among the early onset patients and 26% among the late-onset patients). Among patients who received surgical and medical therapy, the mortality rate was 29.6%, whereas among those who received only medical therapy, a 39.2% mortality rate was reported. According to the extracted data, antibiotic therapy was successful in 72.6% of the patients. In contrast, a combination of surgical and drug-based approaches resulted in a cure in 76.1% of patients. The most common etiological agent was Staphylococcus aureus (38.5%), followed by Enterococcus faecalis (26.9%) and Streptococcus mitis (10.3%). The mortality rate of patients infected with S. aureus was 29.2%, indicating the severity of this infectious agent. Prosthetic valve endocarditis (PVE) is a serious condition associated with a high mortality rate both in the short and long term. Regardless of the therapy used, the risk of death remains high.

Acute kidney injury of mild to moderate severity in patients with COVID-19

THE AIM: to study the incidence of mild to moderate acute kidney injury in patients with COVID-19.PATIENTS AND METHODS. The data of the case histories of 200 patients hospitalized in the infectious diseases department of the Naro-Fominsk Regional Hospital of the Moscow region for COVID-19 were analyzed, mainly with mild to moderate severity of lung damage according to computed tomography, which do not require respiratory support and renal replacement therapy.RESULTS. Despite the fact that the analyzed group of patients did not have the most severe course of COVID-19, the first stage of acute kidney injury was detected in 22.5% of patients, which was manifested by a temporary decrease in hourly diuresis, increased creatinine, urea, proteinuria and erythrocyturia.CONCLUSION. The development of acute kidney injury was most often associated with older age, coronary heart disease, arterial hypertension, diabetes mellitus and obesity.

Clinical and Radiological Features of Pyogenic and Brucellar Spondylodiscitis

Aim: Since spondylodiscitis continues to be seen with increasing incidence; thus, starting antibiotherapy targeted towards the etiological agent is crucial for reducing complications and mortality. This study aimed to determine the clinical and radiological characteristics of spondylodiscitis’ causative microorganisms. Material and Methods: Patients hospitalized in the Department of Infectious Diseases and Clinical Microbiology with a diagnosis of spondylodiscitis between 2015 and 2023 were retrospectively evaluated. Results: Low back pain was present in 97.5% of the total 40 patients as the most common symptom. Tissue biopsy culture results were obtained for 21 (52.5%) patients, with culture positivity observed in five (12.5%) patients. Consumption of raw milk/dairy products in the anamnesis and fever were found to be statistically significantly higher in patients with brucellosis (p &lt; 0.001, p = 0.015), whereas neurological deficits were significantly higher in the pyogenic group (p = 0.007). No significant differences were observed between the pyogenic and brucella spondylodiscitis groups in terms of laboratory parameters (sedimentation rate, C-reactive protein, white blood cell count) and magnetic resonance imaging findings. Conclusion: Since no distinctive clinical and radiological parameters were identified for distinguishing between brucellar and pyogenic spondylodiscitis, serological tests for brucellosis should be investigated when considering the diagnosis, particularly in endemic regions. In cases of pyogenic spondylodiscitis, empirical antibiotic use prior to pathogen isolation may lead to delays in diagnosis and appropriate treatment, potentially resulting in complications such as neurological deficits. Therefore, interventional methods for tissue biopsy culture should be planned before antibiotherapy, especially in patients who do not immediately require antibiotherapy.

Clinical analysis of cases of otogenic sigmoid sinus thrombosis in children

Objective:To analyze the clinical characteristics of middle ear mastoiditis combined with sigmoid sinus thrombophlebitis in children. Methods:Author retrospectively analyzed the clinical data of 6 children with middle ear mastoiditis combined with sigmoid sinus thrombophlebitis who were hospitalized in the Department of Infectious Diseases and Department of Neurology with first diagnosis of fever/headache, and subsequently underwent middle ear mastoidectomy in our department. All patients underwent comprehensive otoscopic, audiologic, imaging, and pathogenetic examinations. Clinical manifestations, pathogenetic features, treatment methods and prognosis were summarized, and the follow-up period was 3-6 months. Results:All 6 cases were first diagnosed with intracranial complications such as fever and headache in the internal medicine department. Within one month, all patients developed ear symptoms including pain, discharge, and hearing loss. Audiologic examination revealed conductive hearing loss in five cases and total deafness in one case. MRI, MRV and MRA examinations suggested that there were 6 cases of middle ear infection combined with thrombophlebitis of the ethmoid sinus, of which 3 cases had thrombus in the ethmoid sinus. 6 cases received surgical treatments: 2 cases of radical mastoidectomy+grommet Insertion, and 4 cases of radical mastoidectomy. Pathogenetic examination identified Streptococcus pneumoniae in three cases, Pseudomonas aeruginosa in one case, Enterobacter cloacae complex in one case, and no pathogens were detected in one case. Postoperative pathology was inflammatory granulation in all 6 cases. Follow-up was 3-6 months with no recurrence of intracranial and middle ear lesions on regular review. Conclusion:Children with recurrent fever, headache, and a recent history of acute and chronic otitis media should be evaluated for the possibility of sigmoid sinus thrombophlebitis, and imaging tests should be performed in a timely manner to clarify the diagnosis. Once diagnosed, surgery to remove the lesions around the ethmoid sinus, smooth drainage combined with antibiotic therapy is the most direct and effective treatment, and anticoagulation therapy is given when necessary. Timely diagnosis, multidisciplinary collaboration, and accurate timing of the management of primary foci and comorbidities are crucial to the treatment of the disease.

Reactive hemophagocytic lymphohistiocytosis: Epidemiological, clinico-biological and etiological profile

Hemophagocytic lymphohistiocytosis (HLH) is an hyperinflammatory state resulting from increased secretion of proinflammatory cytokines, which are responsible for clinical, biological and cytological manifestations. ObjectiveThe aim of our study is to describe the epidemiological, clinical, biological, etiological and evolutionary profile of HLH in Tunisia. MethodsA retrospective study that involved patients, with images of hemophagocytosis in myelograms analyzed at the laboratory of biological hematology of the University Hospital "Hédi-Chaker" of Sfax-Tunisia, followed at these departments: hematology, internal medicine, department of infectious-diseases and department of gastroenterology, (June2017- May2021). First, we identified all patients with hemophagocytosis images. Secondly, we selected the patients who fulfilled the diagnostic criteria of the HLH-2004-score. ResultsNineteen patients were included in this study. Nine men and 10 women with a mean age of 37.95 years. Fever was present in all patients. Organomegaly was described in 74% of cases. The most frequent cytopenia was anemia (100%). Hypertriglyceridemia was noted in 79% of cases and hyperferritinemia (> 500 ng/mL) was ubiquitous. In myelogram, 68% of patients had slides showing numerous or very numerous images of hemophagocytosis. The infectious pathology was the most common cause of HLH (42%). No cause was found in 10% of cases. The corticosteroid therapy at a dose of 1 mg/kg/day was prescribed in 89% of our patients. The overall evolution was favorable in 58% of cases. The mortality was not associated with the causal pathology (p=0.218). ConclusionSecondary HLH is likely to be under-recognized, which contributes to its high morbidity and mortality. Early recognition is crucial for any reasonable attempt at curative therapy.

Clinical and epidemiological analysis of intestinal infections in a children's infectious diseases hospital, experience in using the PEWS scale

Purpose of the work: to conduct a clinical-epidemiological analysis of intestinal infections in a pediatric infectious diseases hospital and the effectiveness of the PEWS scale.Materials and methods: a retrospective study was conducted at the Moscow City Clinical Hospital «Communarka» and City Clinical Hospital No. 1 in the pediatric infectious disease departments from June 1, 2023, to August 31, 2023. Laboratory, clinical, and anamnestic data were obtained from the medical information system «EMIAS» and the laboratory information system (LIS) «ALISA». The study analyzed 838 medical records of children with acute respiratory infections.Results: when conducting a statistical analysis of indicators in two groups (group 1 — PEWS ≥ 3 points, recorded at least once during the entire period of hospitalization, group 2 — PEWS from 1 to 2 points, recorded at least once during hospitalization period) no significant differences were observed in terms of etiology, age, day of illness, blood test results, and length of hospital stay. All patients had a moderate form of acute respiratory infection, however, patients with PEWS ≥ 3 points required increased attention from medical staff and had a higher risk of deterioration without additional medical intervention, with the most significant risk in predicting deterioration being related to changes in the cardiovascular system. All children were discharged home in satisfactory condition with PEWS = 0.Conclusion: In our conducted research, for the first time in the Russian Federation, the experience of using the PEWS scale in pediatric practice for patients with gastrointestinal infections was applied with the aim of early detection of the risk of clinical deterioration. It can be assumed that the most significant risk in predicting deterioration in the condition of a child with acute gastrointestinal infection, as well as with acute respiratory infection, is predominantly due to disturbances in the cardiovascular system.

Knowledge, attitudes, and practices (KAPs) regarding tick-borne rickettsial disease among medical staff in endemic areas of China.

Tick-borne rickettsial disease (TBRD) is a perilous acute infection that often eludes diagnosis in its early stages. The triad of knowledge, attitudes, and practices (KAPs) among medical professionals is key to reducing missed diagnosis rates. Therefore, a meticulous evaluation of KAPs is imperative. This study aimed to delve into the understanding of TBRD and explore the beliefs and practices related to personal prevention methods among individuals in Lu'an, a hotspot for TBRD. During the summer months of 2023, convenience sampling was employed by circulating a confidential questionnaire to 1,206 participants in the endemic regions of China. This questionnaire painted a comprehensive picture of the participants' sociodemographic profiles and their KAPs levels vis-à-vis TBRD. The findings revealed that participants scored a mere 55.78% in knowledge, while their attitudes and practices garnered impressive scores of 90.09% and 90.83%, respectively. Upon further analysis using multiple linear regression, several intriguing patterns emerged. Male participants, employed in the Infectious Disease Department, held vice-senior or higher titles, or had prior medical training demonstrated superior knowledge scores. On the other hand, medical personnel who were younger than 30, possessed graduate degrees or higher qualifications, and had training excelled in attitudes and practices. Notably, when employing the Boston Consulting Group (BCG) matrix, a significant distribution of medical personnel was observed across the four quadrants. Specifically, 37.43%, 13.19%, 19.61%, and 29.77% fell into the first, second, third, and fourth quadrants. This survey underscores the commendable attitudes and practices of medical staff towards TBRD in endemic regions of China. However, their knowledge level remains wanting and demands urgent improvement.

The effect of early remdesivir administration in COVID-19 disease progression in hospitalised patients.

Antiviral drugs have become crucial in managing COVID-19, reducing complications and mortality. Remdesivir has emerged as an effective therapeutic drug for hospitalized patients at risk of disease progression, especially when alternative treatments are infeasible. While the recommended treatment duration of remdesivir extends up to 7days post-symptom onset, this study examines how early remdesivir administration impacts clinical outcomes. We conducted aretrospective analysis using clinical data from consecutively PCR confirmed SARS-CoV‑2 adult patients (≥ 18years) who received remdesivir during their hospitalization at the department of infectious diseases, Klinik Favoriten in Vienna. The data covered the period from July1, 2021, to April31, 2022. Patients were divided into two groups based on the timing of remdesivir administration: an early group (0-3days since symptom onset) and alate group (≥ 4days since symptom onset). The primary outcome was in-hospital disease progression, assessed using the WHO COVID-19 Clinical Progression Scale (≥ 1point increase). Multivariable logistic regression, adjusted for age, sex, SARS-CoV‑2 variant, and COVID-19 vaccination status, was used to assess clinical outcomes. In total 219 patients were included of whom 148 (67.6%) were in the early group and 71(32.4%) were in the late group. The average age was 66.5 (SD: 18.0) years, 68.9% of the patients were vaccinated, and 72.6% had the Omicron virus variant. Late remdesivir administration was associated with asignificantly higher probability of needing high-flow oxygen therapy (OR 2.52, 95% CI 1.40-4.52, p = 0.002) and ICU admission (OR 4.34, 95% CI 1.38-13.67, p = 0.012) after adjusting for confounders. In the late group there was atrend towards ahigher risk of clinical worsening (OR 2.13, 95% CI 0.98-4.64, p = 0.056) and need for any oxygen therapy (OR 1.85, 95% CI 0.94-3.64, p = 0.074). Compared to patients who received remdesivir within the first 3days after symptom onset, administering remdesivir after day3 in hospitalized COVID-19 patients is associated with higher risk for complications, such as the need for high-flow oxygen therapy and ICU admission.

Renal and Hemorrhagic Complications Following Bee Sting Envenomation: A Case Report from the Hospital of Zinder

Renal and hemorrhagic complications following envenomation by bee stings are rare, posing significant problems for early diagnosis and treatment in the clinical setting. Bee venom is generally well tolerated. A 44-year-old patient was admitted to the infectious and tropical diseases department of the Zinder National Hospital with cervicofacial edema following bee stings. Initially, the patient lost consciousness. Respiratory symptoms included dyspnea and 91% desaturation on room air. The patient was put on oxygen to alleviate hypoxia, doxycycline to prevent secondary bacterial infections, and prednisone to reduce inflammation. The clinical picture was complicated by a worsening of the patient's condition due to a deterioration in renal function, and the subsequent appearance of hematemesis. A renal biopsy revealed acute tubulointerstitial nephropathy, due to direct venom toxicity on the tubules. He was discharged after 35 days. We report a rare case of bee sting complicated by hemorrhagic syndrome and renal involvement.

The Place of Generic Medicines in Hospital Prescriptions: A Survey Conducted in Medical Departments of the University Hospital of Marrakesh, Morocco.

A generic medication is a copy of an original drug for which the patent has expired. It contains the same active substances and is equivalent in terms of safety, efficacy, and pharmaceutical quality. Generic drugs are produced after the expiration of the brand-name drug's patent, which enables greater competition and reduces costs for patients and healthcare systems. They are subjected to strict regulatory and quality control standards to ensure compliance with pharmaceutical norms. This study aims to determine the current status of generic drug prescribing within the medical departments of the Mohammed VI University Hospital (UH) of Marrakesh. This is a cross-sectional study with descriptive and analytical aims, involving 224 prescriptions issued in the medical departments of the Mohammed VI University Hospital (UH) of Marrakesh. To obtain the data required for the study, we included medical records, prescription sheets, and prescriptions delivered to hospitalized patients. In our study, 224prescriptions were analyzed, with an overall total of 989 prescribed drugs, and a mean of 4.42 +- 2.39 drugs per prescription. Prescriptions from the Psychiatry Department accounted for 258 (26.09%) of total prescriptions, followed by those from the Cardiology Department at 130 (13.14%)and the Internal Medicine Department at 114 (11.53%). The generic prescribing rate for the UH's medical departments was 403 (40.75%). The Oncology Department had the highest generic prescribing rate (27 (64.29%)), followed by the Infectious Diseases and Rheumatology departments, at 29 (63.04%) and 34 (60.71%), respectively. In contrast, the Psychiatry Department had a generic prescribing rate of just 54 (20.93%). The most frequently prescribed classes as generic drugs were gastric antisecretory agents at 39 (100%), antiemetics at 32 (94.12%), and antivirals at nine (81.82%). The vast majority of drugs, 896 (90.59%), were reimbursable. In conclusion, we have noted that the generic drug prescription rate at the UH remains average compared with other institutions, and needs to be improved to optimize resources and control healthcare costs.

Thoughts on and Proposal for the Education, Training, and Recruitment of Infectious Disease Specialists.

The global pandemic of COVID-19 has underscored the significance of establishing and sustaining a practical and efficient infection control system for the benefit and welfare of society. Infectious disease (ID) specialists are expected to take on leadership roles in enhancing organizational infrastructures for infection prevention and control (IPC) at the hospital, community, and national levels. However, due to an absolute shortage and an uneven distribution, many core hospitals currently lack the ID specialists. Given the escalating global risk of emerging and re-emerging infectious diseases as well as antimicrobial resistance pathogens, the education and training of ID specialists constitutes an imperative concern. As demonstrated by historical changes in the healthcare reimbursement system, the establishment and enhancement of IPC measures is pivotal to ensuring medical safety. The existing structure of academic society-driven certification and training initiatives for ID specialists, contingent upon the discretionary decisions of individual physicians, possesses both quantitative and qualitative shortcomings. In this article, I first address the present situations and challenges related to ID specialists and then introduce my idea of securing ID specialists based on the new concepts and platforms; (i) ID Specialists as National Credentials, (ii) Establishment of the Department of Infectious Diseases in Medical and Graduate Schools, (iii) Endowed ID Educative Courses Funded by Local Government and Pharmaceutical Companies, and (iv) Recruitment of Young Physicians Engaged in Healthcare Services in Remote Areas. As clarified by the COVID-19 pandemic, ID specialists play a crucial role in safeguarding public health. Hopefully, this article will advance the discussion and organizational reform for the education and training of ID specialists.

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

Background: We investigated the current state of frailty in elderly patients with tuberculosis and analyzed the factors that influence it. Methods: 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. Results: 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. Conclusion: 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 &lt;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.
