Abstract Background Tropheryma whipplei pneumonia is an infrequent medical condition. The clinical symptoms associated with this disease are nonspecific, often resulting in misdiagnosis or missed diagnosis. Therefore, sharing and summarizing the experiences diagnosis treatment of can deepen global understanding awareness it. Case presentation patient a 78-year-old married Han Chinese female who was admitted to hospital after experiencing fever, dry cough, fatigue for 4 days. A lung computed tomography scan revealed inflammatory exudation lower left lung, accompanied by pleural effusion. bronchoalveolar lavage fluid subjected further analysis using metagenomic next-generation sequencing, which identified 41 genetic sequences . Consequently, she diagnosed pneumonia. After initiating doxycycline biapenem, patient’s showed significant improvement. Upon discharge, continued combination hydroxychloroquine, discontinued At 12-month follow-up, reported overall good health, no any other discomfort.

Query fever (Q fever), a zoonotic disease, caused by Coxiella burnetii, is an infectious disease that has long been considered rare and regionally restricted disease. It can be responsible for endocarditis endovascular infections. Systemic capillary leak syndrome (SCLS), of unknown etiology most commonly develops in adults 50–70 years age, diagnosed clinically based on characteristic symptomatic triad hypotension, hemoconcentration (elevated hemoglobin or hematocrit), serum hypoalbuminemia resulting from fluid extravasation. Although Q increasingly recognized reported recent years, the treatment complicated SCLS, with etiological diagnosis aided metagenomic next-generation sequencing (mNGS), remains uncommon. This report describes case acute concurrent SCLS 54-year-old male who worked slaughterhouse. The patient presented fever, chest tightness, shortness breath, accompanied severe headache. His condition rapidly deteriorated, leading to generalized weakness, hypotension. Due respiratory failure shock, he was admitted intensive care unit (ICU) treatment. Despite empirical antibiotic therapy along resuscitation, his blood pressure continued decline, metabolic acidosis distress worsened. As failed improve, tracheal intubation performed. mNGS detected both burnetii BALF samples. Based results, started doxycycline, alongside penicillin antibiotics, vasopressors, continuous renal replacement (CRRT). patient's gradually improved, discharged home after 12 days At 90-day follow-up, had nearly fully recovered pre-illness status. plays crucial role assisting which enables timely underlying triggering SCLS. This, combined restrictive resuscitation strategies, essential improving outcomes.

Abstract Background Effective infectious disease diagnostics (IDD) are vital for informing clinical decision-making regarding the treatment and patient management of infections. In England, conventional methods rely upon culture-dependent techniques, there has been little shift in acceptance integration culture-independent sequencing into routine IDD. This study explored stakeholders’ experiences within IDD, including those working settings conducting research at forefront microbial genomics. From participants’ experiences, aimed to identify barriers facilitators driving development implementation metagenome as a diagnostic. Methods Virtual semi-structured interviews were conducted with purposively selected individuals involved The implementing diagnostic tool decisions about which used identifying bacteria-causing Thematic analysis was analyse data, an Interpretive Phenomenological approach throughout. Results Ten interviewed between July 2021 October 2021, scientists, consultants, professors academia. Their experience ranged from limited knowledge expert understanding phenomenon. thoughts perspectives participants could be grouped five themes: Availability diseases; Clinical laboratory infrastructure; Ethical Data Sharing: Enhancing metagenomics through Open Access; Case action: COVID-19; importance communication improve developments new diagnostics. Participants recognised need implemented overcome limitations current approaches but highlighted integrating settings, such impact on decision-making, accreditation, cost. Further, felt that lessons learnt using COVID-19 how other platforms have integrated over last 20 years. Conclusions provided insights opinions address gap literature identified drive IDD settings. Knowledge upcoming genomic testing is not equally distributed throughout UK, impacting integrate Improvements access positively population health.

An increasing number of critically ill patients are immunocompromised. These at high risk intensive care unit (ICU) admission because numerous complications. Acute respiratory failure due to severe community-acquired pneumonia (SCAP) is one the leading causes admission. Early targeted antibiotic therapy crucial for improving prognosis these patients. Metagenomic next-generation sequencing (mNGS) in bronchoalveolar lavage fluid (BALF) has shown significant value pathogen detection recent years. However, there few studies on summarizing profiles SCAP immunocompromised We performed a multicenter retrospective analysis with ICU diagnosed between May 2021 October 2024. Bronchoalveolar (BALF), blood, and sputum samples were collected subjected mNGS conventional microbiological tests (CMTs). The detected by two methods compared. In our study, compared CMTs, increased rates mixed infections group (58.82% vs 17.96%, P < 0.05) immunocompetent (44.58% 18.72%, 0.05), while also reducing rate no (4.90% 38.73%, 0.05; 8.37% 32.76%, 0.05). both groups, proportion positive clinical impacts (diagnosis) resulting from results exceeded 90% (96.57% 93.84%), treatment effectiveness was higher than (65.69% 56.40%, Further showed that when mNGS-guided effective, 28-day mortality significantly improved (31.34% 74.29%, (42.36% 40.68%, ineffective. This study indicates SCAP, particularly those who immunocompromised, more likely have polymicrobial infections. BALF provides rapid comprehensive profiling pulmonary infections, thereby having impact diagnosis, SCAP.

As survival increases after allogeneic hematopoietic stem cell transplantation (allo-HCT), several organ complications have emerged, including those involving the lung, which require a multidisciplinary management approach. The constant evolution of allo-HCT procedures, advances in diagnostic tools for infections and pulmonary disease, as well new treatment approaches, frequent updating knowledge this field. We review multiple infectious noninfectious lung that occur both early late allo-HCT. This includes an updated description these complications, risk factors, approach outcome. A literature search was performed using PubMed-indexed journals. diagnosis remains challenging, further complicated by association co-infections and/or links between infection complications. development metagenomic next-generation sequencing (mNGS) should enhance yield bronchoalveolar lavage but its clinical relevance to be evaluated. better understanding pathophysiology chronic graft-versus-host disease (GVHD) improved phenotyping are essential advancing therapeutic management. requires revision criteria identification biomarkers disease.

Acute lower respiratory tract infections (ALRIs) is a leading cause of child mortality worldwide. Metagenomic next-generation sequencing (mNGS) identifies ALRIs pathogens and explores the lung microbiota's role in disease severity clinical outcomes. This study examines association between microbiota outcomes children, exploring its potential as prognostic biomarker.
