Abstract
OBJECTIVE Bone marrow examination is valuable for identifying the cause of fever of unknown origin (FUO) in HIV-infected patients. Based on the outcomes of bone marrow examination of patients with FUO, we aimed to develop a predictive model for identifying the factors that can increase the diagnostic yield of bone marrow examination. DESIGN For this retrospective cohort study, we enrolled HIV-infected patients, aged more than 15 years and diagnosed with FUO, at Songklanakarind Hospital in Southern Thailand, between January 2009 and December 2019. METHODS Evaluations were based on bone marrow aspiration, biopsy, and culture; any missing data were imputed with regression imputation. RESULTS Among the final 108 included patients, 44 (40.74%) showed positive bone marrow results. The diagnoses mainly comprised histoplasmosis, penicilliosis, and tuberculosis. Bone marrow examination led to treatment modifications in approximately 33% patients. Platelet count less than 150 000 cells/μl, alkaline phosphatase (ALP) level at least 200 U/l, and no previous antibiotic treatment were significantly associated with higher diagnostic yields. The HIV bone marrow (HIVBM) model, comprising of spleen size, hematocrit (Hct), platelet count before bone marrow examination, ALP level at admission, and previous antibiotic treatment, was generated as a nomogram to predict the diagnostic yield of bone marrow examination in HIV-infected patients with FUO. CONCLUSION The results of this study indicate that the HIVBM model can be used to predict the diagnostic yield of bone marrow examination, and therefore assist in clinical decision-making regarding bone marrow procedures, to be performed for identifying the origin of fever in HIV-infected patients.

Abstract
INTRODUCTION Febrile conditions often have an infectious etiology. However, there are also fevers associated with occupational exposures. A detailed occupational history can hold the key to the diagnosis. In the case of exposure to organic dusts, the development of hypersensitivity pneumonitis (HP) is possible. Thus, HP should be considered in the presence of interstitial lung disease of unclear etiology. Failure to recognize this can have dramatic consequences and, in extreme cases, lead to lung transplantation. Differentially, organic dust toxic syndrome (ODTS) must be considered. The syndrome of metal fume fever provoked by inhalation of inorganic substances is usually benign and self-limiting. The disease manifests with fever, cough, and flu-like sensations.

Abstract
INTRODUCTION Fever of unknown origin (FUO) remains one of the most challenging clinical conditions. It demands an exhaustive diagnostic approach, considering its varied etiologies spanning infectious, autoimmune, inflammatory, and malignant causes. PATIENT CONCERNS This report shows the journey of diagnosing a 28-year-old male who presented with persistent fever and lower-extremity weakness over 9 months. Despite seeking care at multiple hospitals, a definitive diagnosis remained elusive. DIAGNOSIS The patient underwent a series of evaluations in various specialties, including gastroenterology, infectious diseases, rheumatology, hematology, and cardiology. Multiple tests and treatments were administered, including antiviral therapy for hepatitis B and antibiotics for suspected infections. INTERVENTIONS After an initial misdiagnosis and unsuccessful treatments, a positron emission tomography-computed tomography scan and lymph node biopsy ultimately led to the diagnosis of peripheral T-cell lymphoma-T follicular helper type (PTCL-TFH) lymphoma. The patient was referred to the hematology clinic and initiated on CHOEP (cyclophosphamide, vincristine, etoposide, and prednisone) chemotherapy. OUTCOMES The patient showed a positive response to CHOEP therapy, as indicated by a posttreatment positron emission tomography-computed tomography scan. He reported a significant improvement in his quality of life. Additional rounds of the same regimen were planned to further manage the lymphoma. CONCLUSION This case emphasizes the importance of a comprehensive and persistent diagnostic approach in managing FUO. Initially, the focus on infectious causes led to extensive treatments, but the disease's progression and complications shifted attention to other specialties. The eventual diagnosis of PTCL-TFH lymphoma highlights the significance of advanced imaging techniques and multidisciplinary collaboration in uncovering elusive diagnoses. Thorough surveillance, timely reassessments, and repeated testing can uncover definitive changes critical for diagnosis. PTCL-TFH lymphoma, although rare, should be considered in the differential diagnosis of FUO, especially when initial evaluations are inconclusive.

Abstract
Fever of unknown origin in adolescents is a challenging disease state for which potential underlying etiology can include infectious, non-infectious inflammatory, and malignancy processes. Careful and thorough history (including exposure history), serial examination, and targeted laboratory and imaging testing is critical for these patients. In adolescents in which an etiology is discovered, infectious etiology remains the most prevalent, followed by non-infectious inflammatory diseases. In patients with non-diagnostic overall reassuring work up, the prognosis is typically self-limiting and favorable.

Abstract
BACKGROUND While presumably less common with modern molecular diagnostic and imaging techniques, fever of unknown origin (FUO) remains a challenge in kidney transplant recipients (KTRs). Additionally, the impact of FUO on patient and graft survival is poorly described. METHODS A cohort of adult KTRs between January 1, 1995 and December 31, 2018 was followed at the University of Wisconsin Hospital. Patients transplanted from January 1, 1995 to December 31, 2005 were included in the "early era"; patients transplanted from January 1, 2006 to December 31, 2018 were included in the "modern era". The primary objective was to describe the epidemiology and etiology of FUO diagnoses over time. Secondary outcomes included rejection, graft and patient survival. RESULTS There were 5590 kidney transplants at our center during the study window. FUO was identified in 323 patients with an overall incidence rate of .8/100 person-years. Considering only the first 3 years after transplant, the incidence of FUO was significantly lower in the modern era than in the early era, with an Incidence Rate Ratio (IRR) per 100 person-years of .48; 95% CI: .35-.63; p < .001. A total of 102 (31.9%) of 323 patients had an etiology determined within 90 days after FUO diagnosis: 100 were infectious, and two were malignancies. In the modern era, FUO remained significantly associated with rejection (HR = 44.1; 95% CI: 16.6-102; p < .001) but not graft failure (HR = 1.21; 95% CI: .68-2.18; p = .52) total graft loss (HR = 1.17; 95% CI: .85-1.62; p = .34), or death (HR = 1.17; 95% CI: .79-1.76; p = .43. CONCLUSIONS FUO is less common in KTRs during the modern era. Our study suggests infection remains the most common etiology. FUO remains associated with significant increases in risk of rejection, warranting further inquiry into the management of immunosuppressive medications in SOT recipients in the setting of FUO.

Abstract
INTRODUCTION Fever of unknown origin (FUO) poses a diagnostic challenge, often requiring a systematic evaluation to uncover its elusive cause. This case study delves into the presentation of a 42-year-old Chinese male with persistent fever, muscle pain, and a perplexing rash. PATIENT CONCERNS The patient's symptoms included a prolonged fever, chills, muscle pain, and throat discomfort, with a history of pulmonary tuberculosis. Initial diagnoses of upper respiratory infection and unspecified infection were followed by antibiotic treatments, yet the fever persisted, accompanied by an exacerbating rash. DIAGNOSIS Extensive diagnostic investigations, including laboratory tests, imaging studies, and skin dermoscopy, provided valuable insights. The patient exhibited elevated inflammatory markers, hepatosplenomegaly, lymphadenopathy, and lung nodules. Differential diagnoses included adult-onset Still disease and drug-induced hypersensitivity syndrome. INTERVENTIONS The patient received a series of antibiotic treatments, which initially had limited success. Upon considering an autoimmune etiology, corticosteroids were introduced, followed by cyclosporine. The patient exhibited a positive response to this immunosuppressive therapy. OUTCOMES Treatment adjustments were made, and the patient responded positively to a combination of corticosteroids and cyclosporine. His fever subsided, and laboratory markers normalized. One month after discharge, the patient showed continued improvement. CONCLUSION FUO cases often demand a multidisciplinary approach, considering rare and uncommon diseases. This case underscores the importance of thorough evaluation, collaboration between specialties, and vigilant monitoring of treatment responses. The patient's unique presentation emphasizes the need to consider drug-induced reactions, even when symptoms deviate from typical disease patterns, highlighting the complexities in diagnosing and managing FUO.

Abstract
Accurate and interpretable differential diagnostic technologies are crucial for supporting clinicians in decision-making and treatment-planning for patients with fever of unknown origin (FUO). Existing solutions commonly address the diagnosis of FUO by transforming it into a multi-classification task. However, after the emergence of COVID-19 pandemic, clinicians have recognized the heightened significance of early diagnosis in patients with FUO, particularly for practical needs such as early triage. This has resulted in increased demands for identifying a wider range of etiologies, shorter observation windows, and better model interpretability. In this article, we propose an interpretable hierarchical multimodal neural network framework (iHMNNF) to facilitate early diagnosis of FUO by incorporating medical domain knowledge and leveraging multimodal clinical data. The iHMNNF comprises a top-down hierarchical reasoning framework (Td-HRF) built on the class hierarchy of FUO etiologies, five local attention-based multimodal neural networks (La-MNNs) trained for each parent node of the class hierarchy, and an interpretable module based on layer-wise relevance propagation (LRP) and attention mechanism. Experimental datasets were collected from electronic health records (EHRs) at a large-scale tertiary grade-A hospital in China, comprising 34,051 hospital admissions of 30,794 FUO patients from January 2011 to October 2020. Our proposed La-MNNs achieved area under the receiver operating characteristic curve (AUROC) values ranging from 0.7809 to 0.9035 across all five decomposed tasks, surpassing competing machine learning (ML) and single-modality deep learning (DL) methods while also providing enhanced interpretability. Furthermore, we explored the feasibility of identifying FUO etiologies using only the first N-hour time series data obtained after admission.

Abstract
Mesenteric panniculitis is a non-neoplastic condition involving inflammation and fibrosis of the small bowel mesentery. We describe a man in his 60s who presented with 3 months of febrile episodes, confusion and weight loss. The diagnosis of mesenteric panniculitis had been established 2 weeks prior based on an abdominal computerized tomography scan. Extensive diagnostic investigations during his hospitalisation were unrevealing, and the symptoms were ultimately attributed to the mesenteric panniculitis. The fevers resolved over several weeks, and no further episodes have occurred since discharge. This case suggests that mesenteric panniculitis merits consideration in the differential diagnosis of fever of unknown origin.

Abstract
Evaluation of patients that may be infected is challenging. Imaging to identify or localize a site of infection is often limited because of the nonspecific nature of the findings on conventional imaging modalities. Available imaging methods lack the ability to determine if antibiotics are reaching the site of infection and are not optimized to follow response to therapy. Positron emission tomography (PET) is a method by which radiolabeled molecules can be used to detect metabolic perturbations or levels of expression of specific targets. The most common PET agent is the glucose analog 2-deoxy-2-[18F]fluoro-D-glucose (18F-FDG). 18F-FDG has some applicability to localizing a site of infection, but its lack of specificity limits its usefulness. There is a need for the development of pathogen-specific PET radiotracers to address the imaging shortcomings noted above. Preclinical and clinical progress has been made, but significant challenges remain.

Abstract
Despite an essential differential diagnosis for fever of unknown origin (FUO) in young adults, adult-onset Still's disease (AOSD) is infrequently considered and remained underdiagnosed in low-middle-income countries. The present study analyzed the clinical, serological, radiological, and pathological characteristics of AOSD presented as FUO in India. A hospital-based retrospective study of patients aged > 13 years admitted with FUO and later diagnosed with AOSD in Postgraduate Institute of Medical Education and Research, Chandigarh (India), was conducted between January 2014 and December 2020. Petersdorf and Beeson's criteria were used to define FUO. The diagnosis of AOSD was made based on Yamaguchi's criteria. Twenty-seven patients (median age 26 years, 14 females) were enrolled. All presented with intermittent fever with a median duration of 10 weeks. The typical features of AOSD at admission were arthralgia (n = 24), hepatosplenomegaly (n = 21), spiking fever ≥ 39 °C (n = 19), lymphadenopathy (n = 18), typical rash (n = 17), and sore throat (n = 11). Leukocytosis (n = 25) and neutrophilia (n = 19) were frequent. Hyperferritinemia was universal (range, 700-145,003 ng/ml; ≥ 2000, n = 23). At admission, AOSD was suspected in only nine FUO cases, while tuberculosis (n = 16), undifferentiated connective tissue disorder (n = 14), and lymphoproliferative disorder (n = 11) were common diagnostic possibilities. Crispin et al. clinical scale detected AOSD in only 15 (55.5%) FUO patients. Whole-body imaging (n = 27), including fluorodeoxyglucose positron emission tomography (n = 12), demonstrated reticuloendothelial organ-system involvement and serositis. Seventeen (63%) patients had macrophage activation syndrome at the time of AOSD diagnosis. AOSD FUO presents with typical but nonspecific features; thus, early differentiation from common causes (e.g., tuberculosis, lymphoma) is difficult. Macrophage activation syndrome is common in AOSD with FUO presentation.

Abstract
Fever is one of the most common chief complaints that brings pediatric patients to seek medical care. Although fever is, in most cases, a physiologic response to a pathogen that has alerted the immune system, prolonged fever can be challenging to work up for the treating pediatrician. In addition to assessing causes of fever, pediatricians must also address the fears that many caregivers may have surrounding elevations in body temperature and provide education as to when fever becomes a concern. Fever can be classified by its duration as well as the presence or absence of associated symptoms. Fever without a source is defined as a fever that has been present for 1 week without a clear cause. Fever of unknown origin is a fever that has been present daily for 8 days or more without an apparent source. This article will walk through considerations for a clinician evaluating a pediatric patient with prolonged fever. [Pediatr Ann. 2023;52(4):e124-e126.].

Abstract
Fever of unknown origin (FUO) is a serious challenge for physicians. The aim of the present study was to consider epidemiology and dynamics of FUO in countries with different economic development. The data of FUO patients hospitalized/followed between 1st July 2016 and 1st July 2021 were collected retrospectively and submitted from referral centers in 21 countries through ID-IRI clinical research platform. The countries were categorized into developing (low-income (LI) and lower middle-income (LMI) economies) and developed countries (upper middle-income (UMI) and high-income (HI) economies). This research included 788 patients. FUO diagnoses were as follows: infections (51.6%; n = 407), neoplasms (11.4%, n = 90), collagen vascular disorders (9.3%, n = 73), undiagnosed (20.1%, n = 158), miscellaneous diseases (7.7%, n = 60). The most common infections were tuberculosis (n = 45, 5.7%), brucellosis (n = 39, 4.9%), rickettsiosis (n = 23, 2.9%), HIV infection (n = 20, 2.5%), and typhoid fever (n = 13, 1.6%). Cardiovascular infections (n = 56, 7.1%) were the most common infectious syndromes. Only collagen vascular disorders were reported significantly more from developed countries (RR = 2.00, 95% CI: 1.19-3.38). FUO had similar characteristics in LI/LMI and UMI/HI countries including the portion of undiagnosed cases (OR, 95% CI; 0.87 (0.65-1.15)), death attributed to FUO (RR = 0.87, 95% CI: 0.65-1.15, p-value = 0.3355), and the mean duration until diagnosis (p = 0.9663). Various aspects of FUO cannot be determined by the economic development solely. Other development indices can be considered in future analyses. Physicians in different countries should be equally prepared for FUO patients.

Abstract
Spontaneous resolution is common in patients with classic fever of unknown origin (FUO). Identifying predictors of spontaneous resolution could reduce the usage of unnecessary, invasive tests or empirical therapy, and furthermore reduce patient anxiety. Identify predictors associated with spontaneous resolution of FUO. A single center, retrospective, cohort study. All hospitalized patients who underwent an [18F] FDG PET-CT scan for the investigation of classical FUO between 1/2012 and 1/2020 were included. We compared patients with spontaneous resolution of fever and clinical symptoms, to those who were diagnosed with a specific etiology of FUO (subdivided to infectious diseases, non-infectious inflammatory diseases (NIID), and malignancies). Epidemiologic characteristics as well as laboratory and PETCT study results were compared. Variables that were found to be associated with spontaneous resolution of FUO on univariate analysis (p < 0.1) were entered into a multivariable regression analysis. The results are reported as odds ratios (OR) and 95% confidence intervals (CI). A total of 303 patients were hospitalized for the investigation of classical FUO and underwent complete assessment. Fever resolved without a diagnosis in 84/303 patients (28%). Variables that were associated with spontaneous resolution of FUO on multivariable analysis included: no anemia, no hypoalbuminemia and no pathological FDG uptake on PET-CT. In 17.8% (15/84) of studies, PET-CT yielded false-positive results that led to additional unnecessary, invasive investigation. Patients without anemia or hypoalbuminemia, and those without uptake on PET-CT are more likely to have spontaneous resolution of classical FUO.

Abstract
Sphingobacterium species are ubiquitous and are abundant in nature and rarely involved in causing human infections. A 62-year-old man presented with recurrent episodes of high fever up to 40 °C accompanied by rigors, sweating, and malaise for the past 4 weeks. After a thorough workup, only elevated C-reactive protein with a leucocytosis was evident. Blood culture showed growth of Gram-negative bacilli which was identified as spingobacterium spiritivorum. Although S. spiritivorum is rare, with limited cases reported in the literature, it must be considered as a causative organism in patients with persistent fevers with sepsis.

Abstract
Importance Patients meeting the criteria for fever of unknown origin (FUO) can be evaluated with structured or nonstructured approaches, but the optimal diagnostic method is unresolved. Objective To analyze differences in diagnostic outcomes among patients undergoing structured or nonstructured diagnostic methods applied to prospective clinical studies. Data Sources PubMed, Embase, Scopus, and Web of Science databases with librarian-generated query strings for FUO, PUO, fever or pyrexia of unknown origin, clinical trial, and prospective studies identified from January 1, 1997, to March 31, 2021. Study Selection Prospective studies meeting any adult FUO definition were included. Articles were excluded if patients did not precisely fit any existing adult FUO definition or studies were not classified as prospective. Data Extraction and Synthesis Abstracted data included years of publication and study period, country, setting (eg, university vs community hospital), defining criteria and category outcome, structured or nonstructured diagnostic protocol evaluation, sex, temperature threshold and measurement, duration of fever and hospitalization before final diagnoses, and contribution of potential diagnostic clues, biochemical and immunological serologic studies, microbiology cultures, histologic analysis, and imaging studies. Structured protocols compared with nonstructured diagnostic methods were analyzed using regression models. Main Outcomes and Measures Overall diagnostic yield was the primary outcome. Results Among the 19 prospective trials with 2627 unique patients included in the analysis (range of patient ages, 10-94 years; 21.0%-55.3% female), diagnoses among FUO series varied across and within World Health Organization (WHO) geographic regions. Use of a structured diagnostic protocol was not significantly associated with higher odds of yielding a diagnosis compared with nonstructured protocols in aggregate (odds ratio [OR], 0.98; 95% CI, 0.65-1.49) or between Western Europe (Belgium, France, the Netherlands, and Spain) (OR, 0.95; 95% CI, 0.49-1.86) and Eastern Europe (Turkey and Romania) (OR, 0.83; 95% CI, 0.41-1.69). Despite the limited number of studies in some regions, analyses based on the 6 WHO geographic areas found differences in the diagnostic yield. Western European studies had the lowest percentage of achieving a diagnosis. Southeast Asia led with infections at 49.0%. Noninfectious inflammatory conditions were most prevalent in the Western Pacific region (34.0%), whereas the Eastern Mediterranean region had the highest proportion of oncologic explanations (24.0%). Conclusions and Relevance In this systematic review and meta-analysis, diagnostic yield varied among WHO regions. Available evidence from prospective studies did not support that structured diagnostic protocols had a significantly better rate of achieving a diagnosis than nonstructured protocols. Clinicians worldwide should incorporate geographical disease prevalence in their evaluation of patients with FUO.

Abstract
OBJECTIVE To date, there is no standard diagnostic practice to identify the underlying disease-causing mechanism for paediatric patients suffering from chronic fever without any specific diagnosis, which is one of the leading causes of death in paediatric patients. Therefore, we aimed this retrospective study to analyse medical records of paediatric patients with fever of unknown origin (FUO) to provide a preliminary basis for improving the diagnostic categories and facilitate the treatment outcomes. DESIGN A retrospective study. SETTING Beijing Children's Hospital. PARTICIPANTS Clinical data were collected from 1288 children between 1 month and 18 years of age diagnosed with FUO at Beijing Children's Hospital between January 2010 and December 2017. INTERVENTIONS According to the aetiological composition, age, duration of fever and laboratory examination results, the diagnostic strategies were analysed and formulated. PRIMARY AND SECONDARY OUTCOME MEASURES The statistical analyses were carried out using SPSS V.24.0 platform along with the χ2 test and analysis of variance (p<0.05). RESULTS The duration of fever ranged from 2 weeks to 2 years, with an average of 6 weeks. There were 656 cases (50.9%) of infectious diseases, 63 cases (4.9%) of non-infectious inflammatory diseases (NIIDs), 86 cases (6.7%) of neoplastic diseases, 343 cases (26.6%) caused by miscellaneous diseases and 140 cases (10.9%) were undiagnosed. With increasing age, the proportion of FUO from infectious diseases gradually decreased from 73.53% to 44.21%. NIID was more common in children over 3 years old, and neoplastic diseases mainly occurred from 1 to 6 years of age. Among miscellaneous diseases, the age distribution was mainly in school-aged children over 6 years. Respiratory tract infection was the most common cause of FUO in children, followed by bloodstream infections. Bacterial infection was the most common cause in children with less than 1 year old, while the virus was the main pathogen in children over 1 year old. CONCLUSIONS The diagnosis of neoplastic diseases and miscellaneous diseases-related diseases still depends mainly on invasive examination. According to our clinical experience, the diagnostic process was formulated based on fever duration and the type of disease. This process can provide a guide for the diagnosis and treatment of paediatric FUO in the future.

Abstract
Fever of unknown origin is defined as a clinically documented temperature of 101°F or higher on several occasions, coupled with an unrevealing diagnostic workup. The differential diagnosis is broad but is typically categorized as infection, malignancy, noninfectious inflammatory disease, or miscellaneous. Most cases in adults occur because of uncommon presentations of common diseases, and up to 75% of cases will resolve spontaneously without reaching a definitive diagnosis. In the absence of localizing signs and symptoms, the workup should begin with a comprehensive history and physical examination to help narrow potential etiologies. Initial testing should include an evaluation for infectious etiologies, malignancies, inflammatory diseases, and miscellaneous causes such as venous thromboembolism and thyroiditis. If erythrocyte sedimentation rate or C-reactive protein levels are elevated and a diagnosis has not been made after initial evaluation, 18F fluorodeoxyglucose positron emission tomography scan, with computed tomography, may be useful in reaching a diagnosis. If noninvasive diagnostic tests are unrevealing, then the invasive test of choice is a tissue biopsy because of the relatively high diagnostic yield. Depending on clinical indications, this may include liver, lymph node, temporal artery, skin, skin-muscle, or bone marrow biopsy. Empiric antimicrobial therapy has not been shown to be effective in the treatment of fever of unknown origin and therefore should be avoided except in patients who are neutropenic, immunocompromised, or critically ill.

Abstract
Introduction The diagnosis of infection-caused fever of unknown origin (FUO) is still challenging, making it difficult for physicians to provide an early effective therapy. Therefore, a novel pathogen detection platform is needed. Metagenomic next-generation sequencing (mNGS) provides an unbiased, comprehensive technique for the sequence-based identification of pathogenic microbes, but the study of the diagnostic values of mNGS in FUO is still limited. Methods In a single-center retrospective cohort study, 175 FUO patients were enrolled, and clinical data were recorded and analyzed to compare mNGS with culture or traditional methods including as smears, serological tests, and nucleic acid amplification testing (NAAT) (traditional PCR, Xpert MTB/RIF, and Xpert MTB/RIF Ultra). Results The blood mNGS could increase the overall rate of new organisms detected in infection-caused FUO by roughly 22.9% and 19.79% in comparison to culture (22/96 vs. 0/96; OR, ∞; p = 0.000) and conventional methods (19/96 vs. 3/96; OR, 6.333; p = 0.001), respectively. Bloodstream infection was among the largest group of those identified, and the blood mNGS could have a 38% improvement in the diagnosis rate compared to culture (19/50 vs. 0/50; OR, ∞; p = 0.000) and 32.0% compared to conventional methods (16/50 vs. 3/50; OR, 5.333; p = 0.004). Among the non-blood samples in infection-caused FUO, we observed that the overall diagnostic performance of mNGS in infectious disease was better than that of conventional methods by 20% (9/45 vs. 2/45; OR, 4.5; p = 0.065), and expectedly, the use of non-blood mNGS in non-bloodstream infection increased the diagnostic rate by 26.2% (8/32 vs. 0/32; OR, ∞; p = 0.008). According to 175 patients’ clinical decision-making, we found that the use of blood mNGS as the first-line investigation could effectively increase 10.9% of diagnosis rate of FUO compared to culture, and the strategy that the mNGS of suspected parts as the second-line test could further benefit infectious patients, improving the diagnosis rate of concurrent infection by 66.7% and 12.5% in non-bloodstream infection, respectively. Conclusion The application of mNGS in the FUO had significantly higher diagnostic efficacy than culture or other conventional methods. In infection-caused FUO patients, application of blood mNGS as the first-line investigation and identification of samples from suspected infection sites as the second-line test could enhance the overall FUO diagnosis rate and serve as a promising optimized diagnostic protocol in the future.

Abstract
BACKGROUND Fever of unknown origin (FUO) is a challenge for clinicians treating patients with HIV/AIDS. CD4 counts can be helpful in the diagnosis and treatment. This study aimed to determine several common etiologies of FUO stratified by CD4 count levels in HIV/AIDS patients. METHODS A cross-sectional retrospective and prospective study was conducted in 195 HIV/AIDS patients with FUO admitted to the National Hospital for Tropical Diseases from January 2016 to June 2019. Clinical parameters, immune status, and etiologies for each patient were recorded. Odds ratios were calculated to compare the distributions of common etiologies in groups with two different CD4 count levels: < 50 cells/mm3 and ≥ 50 cells/mm3. RESULTS The proportions of opportunistic infections and noninfectious etiologies were 93.3% and 3.6%, respectively. Tuberculosis was the most common opportunistic infection (46.7%), followed by talaromycosis (29.2%) and Pneumocystis jiroveci (PCP) infection (20.5%). Tuberculosis was predominant in all CD4 level groups. Most patients with talaromycosis had CD4 counts below 50 cells/mm3. In total, 53.8% of the patients were infected by one pathogen. The risks of tuberculosis and talaromycosis in FUO-HIV patients were high when their CD4 counts were below 50 cells/mm3. CONCLUSIONS Opportunistic infections, especially tuberculosis, are still the leading cause of FUO in HIV/AIDS patients. Tuberculosis and Talaromyces marneffei (TM) infection should be considered in patients with CD4 cell counts < 50 cells/mm3. This study implies that guidelines for appropriate testing to identify the etiology of FUO in HIV/AIDS patient based on the CD4 cell count should be developed, thereby reducing resource waste.

Abstract
Fever of unknown origin represents a clinical syndrome characterized by a fever of over 38.3 °C documented on several occasions during a period of at least 3 weeks, etiology of which remains unexplained after obtaining a detailed history, conducting a thorough physical exam, and an array of basic laboratory tests and diagnostic imaging. Most cases of this syndrome are caused by infections, non-infectious inflammatory diseases, and neoplasms. In addition, drug fevers and internal medicine diseases should be included in the differential diagnostic work-up in all patients. This article presents five case reports of fever of unknown origin managed at an outpatient clinic of a tertiary care center for infectious diseases. This case series emphasizes the need for a consistent, broad and interdisciplinary diagnostic work-up. In addition, we present a review of the etiology and clinical management of fever of unknown origin.

Abstract
BACKGROUND Sometimes, the underlying causes of inflammation cannot be established despite meticulous investigation, including medical history, physical examination, laboratory tests, and radiologic procedures. Rheumatologists are often faced with patients whose condition is known as inflammation of unknown origin (IUO). Differential diagnosis of IUO is diverse, and investigation of these cases is challenging and time-consuming. OBJECTIVE The study aimed to assess the diagnostic role of positron emission tomography/computed tomography (PET/CT) in the evaluation of patients with IUO. METHODS The study sample consisted of 97 adult patients with IUO who have not been previously diagnosed with an infectious, inflammatory, or malignant disease. The necessary data were collected from January 2015 to June 2018 with a 6-month follow-up period. The patients were screened using PET/CT after a specific diagnosis could not be established with detailed laboratory and radiologic evaluations. RESULTS A final diagnosis was established at follow-up, and 47 (54%) of the 97 patients had inflammatory diseases, 30 (34.4%) had malignancies, and 10 (11.4%) had infections. Despite meticulous investigation, 10 patients were left undiagnosed in the follow-up. PET/CT aided diagnosis in 59 patients (60.8%), but it was not helpful in 38 patients (39.2%). PET/CT was positive in 30 (63%) of the 47 patients with inflammatory diseases, whose final diagnosis was inflammatory rheumatic disease, as follows: large-vessel vasculitis in 19 patients, polymyalgia rheumatica in 7 patients, and seronegative arthritis or other rare miscellaneous diseases in 4 patients. The sensitivity of PET/CT was 67% with a specificity and diagnostic accuracy of 100% and 71%, respectively. CONCLUSIONS Investigation of the underlying etiology of IUO is time-consuming and challenging. PET/CT may help identify the final diagnosis more quickly by locating an obscure inflammatory site; thus, it may reduce the number of unnecessary biopsies, diagnostic time, anxiety, work loss, morbidity, and mortality.

Abstract
BACKGROUND In patients with fever or inflammation of unknown origin (fever of unknown origin [FUO] or inflammation of unknown origin [IUO], respectively), expert consensus recommends the use of positron emission tomography with fluorine-18-fluorodeoxy glucose combined with computed tomography (FDG-PET/CT) when standard work-up fails to identify diagnostic clues. However, the clinical variables associated with successful localization of the cause by FDG-PET/CT remain uncertain. Moreover, the long-term outcomes of patients with unexplained FUO or IUO after negative FDG-PET/CT results are unknown. Therefore, we assessed predictors of successful diagnosis of FUO or IUO caused by FDG-PET/CT and associations of spontaneous remission of symptoms with FDG-PET/CT results. METHODS All patients with FUO or IUO, who underwent FDG-PET/CT from 2013 to 2019 because diagnostic work-up failed to identify a cause, were retrospectively included. We calculated the diagnostic yield and performed multivariable logistic regression to assess characteristics previously proposed to be associated with successful localization of FUO or IUO causes. We also assessed whether the FDG-PET/CT results were associated with spontaneous remissions. RESULTS In total, 50 patients with diagnostically challenging FUO or IUO (35 with FUO and 15 with IUO) were assessed. Other than one case of infection, all the identified causes were either malignancy or non-infectious inflammatory diseases (each with 18 patients), and FDG-PET/CT correctly localized the cause in 29 patients (diagnostic yield = 58%). None of the proposed variables was associated with successful localization. All 13 patients with sustained unexplained cause remained alive (median follow-up, 190 days). Spontaneous remission was observed in 4 of 5 patients with a negative FDG-PET/CT, and 1 of 8 with a positive result (P = 0.018). CONCLUSION In the current cohort, the proposed variables were not predictive for successful localization by FDG-PET/CT. A negative FDG-PET/CT scan may be prognostic for spontaneous remission in patients with sustained FUO or IUO.

Abstract
There are over 200 causes of fever of unknown origin (FUO), and although parasitic infection is an increasingly uncommon cause, a definitive diagnosis remains important to ensure rapid treatment and to prevent adverse sequelae through delay. Here, we studied the clinical features and outcomes of patients admitted with FUO and diagnosed with parasitic infection to improve our understanding of the features of parasitic FUO.Medical records of patients admitted to Peking Union Medical College Hospital between 2013 and 2019 with FUO and diagnosed with parasitic infection were reviewed. The clinical features and outcomes of patients for whom follow-up data were available were summarized.Six patients were admitted with FUO and diagnosed with parasitic infections (6/1013; 0.59%). Patients were more commonly middle-aged men and had a relatively long disease course. Most suffered from hyperpyrexia and other non-specific symptoms. Routine examinations were non-specific, and some patients had positive tumor markers, antinuclear antibodies, or positron emission tomography/computed tomography results. Diagnoses were confirmed by bone marrow smears, serum antibody testing, or feces examination. All 6 cases received anthelmintic treatments and recovered well.Parasitic infections must be screened for and actively excluded in FUO patients so that targeted therapy can be rapidly administered to ensure optimal outcomes.

Abstract
Despite the diagnostic means currently available, fever of unknown origin (FUO) remains a diagnostic challenge for the practitioner, requiring a detailed and systematic approach. The etiologies can be classified into 4 main groups: infectious diseases, systemic inflammatory diseases, neoplasia and various rarer entities such as drug-induced or endocrine fevers. A non-negligible percentage of FUOs remains without a clear etiology, generally with a spontaneously favorable evolution. In this article, we propose an algorithm for a step-by-step diagnostic approach and highlight clues that can lead to a diagnosis. However, clinical judgment remains the main pillar in the proposed approach in order to avoid futile investigations.

Abstract
BACKGROUND New hemocytometric parameters can be used to differentiate causes of acute febrile illness (AFI). We evaluated a software algorithm-Infection Manager System (IMS)-which uses hemocytometric data generated by Sysmex hematology analyzers, for its accuracy to detect bacteremia in AFI patients with and without malaria in Burkina Faso. Secondary aims included comparing the accuracy of IMS with C-reactive protein (CRP) and procalcitonin (PCT). METHODS In a prospective observational study, patients of ≥ three-month-old (range 3 months- 90 years) presenting with AFI were enrolled. IMS, blood culture and malaria diagnostics were done upon inclusion and additional diagnostics on clinical indication. CRP, PCT, viral multiplex PCR on nasopharyngeal swabs and bacterial- and malaria PCR were batch-tested retrospectively. Diagnostic classification was done retrospectively using all available data except IMS, CRP and PCT results. FINDINGS A diagnosis was affirmed in 549/914 (60.1%) patients and included malaria (n = 191) bacteremia (n = 69), viral infections (n = 145), and malaria-bacteremia co-infections (n = 47). The overall sensitivity, specificity, and negative predictive value (NPV) of IMS for detection of bacteremia in patients of ≥ 5 years were 97.0% (95% CI: 89.8-99.6), 68.2% (95% CI: 55.6-79.1) and 95.7% (95% CI: 85.5-99.5) respectively, compared to 93.9% (95% CI: 85.2-98.3), 39.4% (95% CI: 27.6-52.2), and 86.7% (95% CI: 69.3-96.2) for CRP at ≥20mg/L. The sensitivity, specificity and NPV of PCT at 0.5 ng/ml were lower at respectively 72.7% (95% CI: 60.4-83.0), 50.0% (95% CI: 37.4-62.6) and 64.7% (95% CI: 50.1-77.6) The diagnostic accuracy of IMS was lower among malaria cases and patients <5 years but remained equal to- or higher than the accuracy of CRP. INTERPRETATION IMS is a new diagnostic tool to differentiate causes of AFI. Its high NPV for bacteremia has the potential to improve antibiotic dispensing practices in healthcare facilities with hematology analyzers. Future studies are needed to evaluate whether IMS, combined with malaria diagnostics, may be used to rationalize antimicrobial prescription in malaria endemic areas.

Abstract
BACKGROUND Our purpose was to provide a detailed clinical description, of symptoms and laboratory abnormalities, and temporality in patients with confirmed Zika and dengue infections, and other acute illnesses of unidentified origin (AIUO). METHODS/ PRINCIPAL FINDINGS This was a two-year, multicenter, observational, prospective, cohort study. We collected data from patients meeting the Pan American Health Organization's modified case-definition criteria for probable Zika infection. We identified Zika, dengue chikungunya by RT-PCR in serum and urine. We compared characteristics between patients with confirmed Zika and dengue infections, Zika and AIUO, and Dengue and AIUO at baseline, Days 3,7,28 and 180 of follow-up. Most episodes (67%) consistent with the PAHO definition of probable Zika could not be confirmed as due to any flavivirus and classified as Acute Illnesses of Unidentified Origin (AIUO). Infections by Zika and dengue accounted for 8.4% and 16% of episodes. Dengue patients presented with fever, generalized non-macular rash, arthralgia, and petechiae more frequently than patients with Zika during the first 10 days of symptoms. Dengue patients presented with more laboratory abnormalities (lower neutrophils, lymphocytosis, thrombocytopenia and abnormal liver function tests), with thrombocytopenia lasting for 28 days. Zika patients had conjunctivitis, photophobia and localized macular rash more frequently than others. Few differences persisted longer than 10 days after symptoms initiation: conjunctivitis in Zika infections, and self-reported rash and petechia in dengue infections. CONCLUSIONS Our study helps characterize the variety and duration of clinical features in patients with Zika, dengue and AIUO. The lack of diagnosis in most patients points to need for better diagnostics to assist clinicians in making specific etiologic diagnoses.

Abstract
Fever of unknown origin is a rare clinical syndrome, that represents a significant diagnostic challenge. There have been described more than 200 potential diseases, that can manifest as a fever of unknown origin. These are classically divided into following categories: infections, non-infectious inflammatory diseases, malignancies, and other miscellaneous disorders. Each of the disease type is associated with rather characteristic symptoms, clinical signs and laboratory findings, which are individually non-specific, but may provide helpful clues for a further focused diagnostic work-up. The clinicians task is to be able to identify these hallmark clinical features and to correctly interpret their significance and limitations in the appropriate differential diagnostic context. The aim of this review is to provide up-to-date clinical research evidence and to propose a concise clue-oriented diagnostic approach.

Abstract
In the early stages of the 2019 novel coronavirus disease (COVID-19) pandemic, containment of disease importation from epidemic areas was essential for outbreak control. This study is based on publicly accessible data on confirmed COVID-19 cases in Taiwan extracted from the Taiwan Centers for Disease Control website. We analysed the characteristics, infection source, symptom presentation, and route of identification of the 321 imported cases that were identified from 21 January to 6 April 2020. They were mostly returned Taiwanese citizens who had travelled to one or more of 37 countries for tourism, business, work, or study. Half of these cases developed symptoms before arrival, most of the remainder developed symptoms 1–13 days (mean 4.0 days) after arrival, and 3.4% never developed symptoms. Three-quarters of the cases had respiratory symptoms, 44.9% had fever, 13.1% lost smell or taste, and 7.2% had diarrhoea. Body temperature and symptom screening at airports identified 32.7% of the cases. Of the remainder, 27.7% were identified during home quarantining, 16.2% were identified via contact tracing, and 23.4% were reported by hospitals. Under the strict enforcement of these measures, the incidence of locally acquired COVID-19 cases in Taiwan remains sporadic. In conclusion, proactive border control measures are effective for preventing community transmission of this disease.

Abstract
OBJECTIVES To improve the diagnostic efficacy of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) for Chinese patients with fever of unknown origin (FUO) and inflammation of unknown origin (IUO), with combined clinical parameters. MATERIALS AND METHODS FUO/IUO patients who underwent a standard diagnostic work-up and 18F-FDG PET/CT scanning were enrolled and divided into a local uptake lesion subgroup and a non-specific abnormal uptake subgroup. Beneficial clinical parameters for improving the diagnostic efficacy of PET/CT were identified. RESULTS From January 2014 to January 2019, 253 FUO/IUO patients were studied. In total, 147 patients had local uptake lesions and 106 patients had non-specific abnormal uptake. In the local uptake lesion group, the positioning accuracy of PET/CT was 37.2% in grades 1 and 2, and 66.3% in grades 3 and 4. With the following combination of clinical parameters, the positioning accuracy increased to 75.0% and 90.0%, respectively: time from admission to performing PET/CT scanning <6.5 days and C-reactive protein level >95 mg/l. In the non-specific abnormal uptake group, the combination of sex (male), bicytopenia, and lactic dehydrogenase improved the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for diagnosing malignancy from 64.3%, 69%, 60%, and 72.7%, respectively, to 83.3%, 81%, 81.4%, and 82.9%, respectively. With the combination of sex (male), white blood count, serum ferritin level, and hepatosplenomegaly, the infection prediction model had a sensitivity, specificity, PPV, and NPV of 78%, 76.2%, 76.6%, and 77.6%, respectively. CONCLUSIONS Combined clinical parameters improved the localization diagnostic value of 18F-FDG PET/CT in the local uptake lesion subgroup and the etiological diagnostic value in the non-specific abnormal uptake subgroup.

Abstract
OBJECTIVE Bone marrow examination (BME) is an important modality for investigation of case of pyrexia of unknown origin (PUO). However, its yield in the diagnosis of infections has not been extensively studied and its role has not been well established. The aim of the study was to investigate the usefulness of BME and to evaluate the etiological and clinico-hematological profile in cases of bone marrow infections. MATERIAL AND METHOD This was a retrospective study where bone marrow cases were retrieved and a review of bone marrow findings with an infectious etiology from July 2014 to June 2018 was done. Detailed history, clinical examination and hematological parameters at presentation were recorded. Clinico-hematological correlation using descriptive statistics was performed. RESULTS The study included 55 cases, on analysis of which the maximum number of infections were those of leishmaniasis accounting for 35%, followed by HIV (29%) and tuberculosis (15%). Other etiological agents included fungal infections (histoplasmosis and aspergillosis), Enteric fever, Scrub typhus, parvovirus, falciparum malaria and filariasis. The most common clinical presentation was fever (80%) and the most common clinical finding was splenomegaly (66%). CONCLUSION Bone marrow examination is an important diagnostic tool to delineate etiological diagnosis in infectious conditions, particularly those presenting with PUO. Moreover, it is particularly important if urgent diagnosis is required or if alternate diagnostic modalities have not revealed a reason for PUO.

Abstract
Fever is the most common reason that children present to Emergency Departments. Clinical signs and symptoms suggestive of bacterial infection are often non-specific, and there is no definitive test for the accurate diagnosis of infection. The 'omics' approaches to identifying biomarkers from the host-response to bacterial infection are promising. In this study, lipidomic analysis was carried out with plasma samples obtained from febrile children with confirmed bacterial infection (n = 20) and confirmed viral infection (n = 20). We show for the first time that bacterial and viral infection produces distinct profile in the host lipidome. Some species of glycerophosphoinositol, sphingomyelin, lysophosphatidylcholine and cholesterol sulfate were higher in the confirmed virus infected group, while some species of fatty acids, glycerophosphocholine, glycerophosphoserine, lactosylceramide and bilirubin were lower in the confirmed virus infected group when compared with confirmed bacterial infected group. A combination of three lipids achieved an area under the receiver operating characteristic (ROC) curve of 0.911 (95% CI 0.81 to 0.98). This pilot study demonstrates the potential of metabolic biomarkers to assist clinicians in distinguishing bacterial from viral infection in febrile children, to facilitate effective clinical management and to the limit inappropriate use of antibiotics.

Abstract
BACKGROUND Fever of unknown origin (FUO) is one of the greatest challenges for clinicians and patients. There are more than 200 etiological agents of FUO, among these the most common is the role of infection, neoplasms, and diseases of connective tissue. The aim of the present study is to investigate the role of the infectious agents parvovirus B19 (B19V) and Coxiella burnetii (C. burnetii) in the development of fever of unknown origin by a set of immunoenzymatic and molecular methods. METHODS The present study included a total of 70 adult patients diagnosed with FUO and hospitalized in Bulgarian Hospitals. A control group of 26 healthy people were also included. Serological (indirect enzyme immunoassay test for detection of B19V and C. burnetii Ph. II specific IgM/IgG) and molecular (extraction and detection of infectious nucleic acids) methods were used. RESULTS From all patients with FUO, a positive result for B19V-IgM was obtained in 18/70 (25.71%, 95% CI: 15.47 - 35.95) and the highest percentage was found in age groups 0 - 9 and 10 - 19 years. Protective B19V immunity and past viral infection was reported in 41/70 (58.57%, 95% CI: 47.03 - 70.11), and this percentage corresponded with the control group 16/26 (61.54%, 95% CI: 42.84 - 80.24). Anti-C. burnetii Ph. II-IgM was demonstrated in 13/70 (18.57%, 95% CI: 9.46 - 27.68). A relatively high percentage of affected patients were ≤ 40 years. Anti-C. burnetii Ph. II-IgG was detected in 24/70 (34.29%, 95% CI: 23.17 - 45.41). The control group has a 100% negative result for acute B19V and C. burnetii infection. A positive B19V-DNA result was obtained in 12/70 (17.14%, 95% CI: 8.31 - 25.97) patients. In 11/12 (91.67%) it was in combination with positive B19V-IgM marker. Of the total 70 sera tested, a positive PCR results for C. burnetii-DNA were obtained in 11 (15.71%, 95% CI: 7.18 - 24.24). According to clinical manifestation and concomitant symptoms, a high percentage of B19V and C. burnetii positives were associated with FUO and fever, headache, chills, and rash. CONCLUSIONS It is of particular importance for a correct diagnosis of FUO to use a combined laboratory approach to prove acute or persistent infection and to test for a set of etiological agents.

Abstract
OBJECTIVE To identify the key diagnostic features and causes of fever of unknown origin (FUO) in Japanese patients. DESIGN Multicentre prospective study. SETTING Sixteen hospitals affiliated with the Japanese Society of Hospital General Medicine, covering the East and West regions of Japan. PARTICIPANTS Patient aged ≥20 years diagnosed with classic FUO (axillary temperature≥38.0°C at least twice within a 3-week period, cause unknown after three outpatient visits or 3 days of hospitalisation). A total of 141 cases met the criteria and were recruited from January 2016 to December 2017. INTERVENTION Japanese standard diagnostic examinations. OUTCOME MEASURES Data collected include usual biochemical blood tests, inflammatory markers (erythrocyte sedimentation rate (ESR), C reactive (CRP) protein level, procalcitonin level), imaging results, autopsy findings (if performed) and final diagnosis. RESULTS The most frequent age group was 65-79 years old (mean: 58.6±9.1 years). The most frequent cause of FUO was non-infectious inflammatory disease. After a 6-month follow-up period, 21.3% of cases remained undiagnosed. The types of diseases causing FUO were significantly correlated with age and prognosis. Between patients with and without a final diagnosis, there was no difference in CRP level between patients with and without a final diagnosis (p=0.121). A significant difference in diagnosis of a causative disease was found between patients who did or did not receive an ESR test (p=0.041). Of the 35 patients with an abnormal ESR value, 28 (80%) had causative disease identified. CONCLUSIONS Age may be a key factor in the differential diagnosis of FUO; the ESR test may be of value in the FUO evaluation process. These results may provide clinicians with insight into the management of FUO to allow adequate treatment according to the cause of the disease.

Abstract
Serious bacterial infection (SBI) is a major cause of morbidity and mortality in children. Distinguishing SBI from self-limiting viral infections is a very important task in the emergency department (ED), especially in the children with fever without source (FWS). The aim of this study was to analyze whether parents' statements about clinical manifestations, which were categorized according to grades, are related to the actual diagnosis of SBI in children with FWS.Retrospective analysis was conducted using prospectively acquired cohort data for all febrile children in the pediatric ED of Seoul National University Hospital from August 2016 to August 2017. The association of clinical manifestations and SBI was the main outcome of this study. The SBIs included diagnoses such as bacteremia, bacterial meningitis, urinary tract infection, and pneumonia. Clinical manifestations including activity, urination, and feeding were categorized into 3 or 4 grades according to the parents' statements. The linear-by-linear association test was used to examine linear associations between the severity of clinical manifestations and SBI. Receiver operating characteristic curves for clinical manifestations were constructed for patients with SBI. Area under the curve (AUC) statistics and 95% confidence intervals (CIs) were obtained to evaluate the predictive performance of clinical manifestations.There was no linear association between SBI and non-SBI when compared by severity of the clinical manifestations, such as duration of fever (P = .299), activity (P = .781), feeding (P = .161), and urination (P = .834). The AUC was 0.54 (95% CI 0.41-0.67) for duration of fever, 0.52 for activity (95% CI 0.40-0.64), 0.42 for feeding (95% CI 0.32-0.53), and 0.51 for urination (95% CI 0.39-0.62).There was no evidence that the test performance of the clinical manifestations is valid for predicting SBIs, even considering the severity of manifestations. For optimal evaluation of the children with FWS, more comprehensive approach including laboratory tests, are needed.

Abstract
RATIONALE Fungal infectious disease does not usually occur in low-risk patients. Clinicians tend to ignore the role of fungi in the fevers of low-risk patients. If there is not timely control of fungal infections and associated fever, the disease will continue to worsen, resulting in physical dysfunction or death. PATIENT CONCERNS Recurrent fever continued for 1 month in a young adult. DIAGNOSES AND INTERVENTIONS Non-albicans Candida (NAC) species probably was the main pathogen in this case based on the resolution of fever after capsofungin administration. OUTCOMES The fever and the associated indicators, including white blood cell count, C-reaction protein, erythrocyte sedimentation rate, and BDG levels, showed improvement quickly. The patient left the hospital successfully after 18 days of caspofungin treatment. There was no recurrent fever at a follow-up of 1 year. LESSONS Clinicians should be aware that the incidence of fungal infection is increasing in low-risk patients. The BDG assay is still an effective tool used to diagnose invasive fungal diseases. Caspofungin is an effective drug for the treatment of some unknown fungal infections.

Abstract
BACKGROUND Fever of unknown origin (FUO) and inflammation of unknown origin (IUO) are challenging medical problems. Previous studies have shown that 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) plays an important role in the diagnosis of FUO, but few studies have explored this diagnostic technique in relation to IUO. PURPOSE To systematically review and perform a meta-analysis of published data on the diagnostic performance of PET/CT in the diagnosis of FUO and IUO. MATERIAL AND METHODS A comprehensive literature search was performed in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines published in March 2018. Meta-analysis of diagnostic performance was performed using STATA 12.0 software. Subgroup analysis was performed by stratification based on study design, number of patients, geographic area, and final diagnosis based on 18F-FDG PET/CT. Meta-regression analyses were performed to recognize heterogeneity. RESULTS Our meta-analysis included 23 studies, comprising a total sample size of 1927 patients. The pooled diagnosis performance was calculated with a per-patient-based analysis: sensitivity = 0.84 (95% confidence interval [CI] = 0.79-0.89), specificity = 0.63 (95% CI = 0.49-0.75), positive likelihood ratio = 2.3 (95% CI = 1.5-3.4), negative likelihood ratio = 0.25 (95% CI = 0.16-0.38), diagnostic odds ratio = 9 (95% CI = 4.0-20), and AUC = 0.84 (95% CI = 0.81-0.87). CONCLUSION In patients with non-specific symptoms and signs, 18F-FDG PET/CT is very helpful for recognizing and excluding diseases, directing further diagnostic decisions, and avoiding unnecessary invasive examinations. We recommend that 18F-FDG PET/CT should be considered among the first-line diagnostic tools for patients with FUO and IUO.

Abstract
BACKGROUND Distinguishing arboviral infections from bacterial causes of febrile illness is of great importance for clinical management. The Infection Manager System (IMS) is a novel diagnostic algorithm equipped on a Sysmex hematology analyzer that evaluates the host response using novel techniques that quantify cellular activation and cell membrane composition. The aim of this study was to train and validate the IMS to differentiate between arboviral and common bacterial infections in Southeast Asia and compare its performance against C-reactive protein (CRP) and procalcitonin (PCT). METHODOLOGY/PRINCIPAL FINDINGS 600 adult Indonesian patients with acute febrile illness were enrolled in a prospective cohort study and analyzed using a structured diagnostic protocol. The IMS was first trained on the first 200 patients and subsequently validated using the complete cohort. A definite infectious etiology could be determined in 190 of 463 evaluable patients (41%), including 89 arboviral infections (81 dengue and 8 chikungunya), 94 bacterial infections (26 murine typhus, 16 salmonellosis, 6 leptospirosis and 46 cosmopolitan bacterial infections), 3 concomitant arboviral-bacterial infections, and 4 malaria infections. The IMS detected inflammation in all but two participants. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the IMS for arboviral infections were 69.7%, 97.9%, 96.9%, and 77.3%, respectively, and for bacterial infections 77.7%, 93.3%, 92.4%, and 79.8%. Inflammation remained unclassified in 19.1% and 22.5% of patients with a proven bacterial or arboviral infection. When cases of unclassified inflammation were grouped in the bacterial etiology group, the NPV for bacterial infection was 95.5%. IMS performed comparable to CRP and outperformed PCT in this cohort. CONCLUSIONS/SIGNIFICANCE The IMS is an automated, easy to use, novel diagnostic tool that allows rapid differentiation between common causes of febrile illness in Southeast Asia.

Abstract
Fever of unknown origin (FUO) is a frequently observed phenomenon in clinical practice. The present study was aimed to investigate potential causes of FUO, thereby improving clinical diagnosis of this disorder.In this retrospective study, clinical data were collected from 215 patients who were diagnosed with FUO between January 2009 and December 2010, and an 18 to 36 months follow-up visit was also performed for these patients.Among these FUO cases, the most common causes of the disease were infectious diseases (IDs) (42.3%), followed by connective tissue diseases (CTDs) (32.1%), miscellaneous (Mi) (10.7%) and neoplasm (N) (6.5%), while the causes for the other 18 cases (8.4%) were still unknown. The most common types of ID, CTD, and N were tuberculosis (16/91, 17.6%), adult onset Still disease (AOSD) (37/69, 53.6%) and non-Hodgkin lymphoma (6/14, 42.9%), respectively.IDs still represent the most common causes of FUO. Regularly intermittent fever with urinary infections and irregularly intermittent fever with infective endocarditis may be regarded as some signs in clinical diagnosis of FUO.

Abstract
BACKGROUND Fever and neutropenia (FN) clinical decision rules (CDRs) are recommended to help distinguish children with cancer at high and low risk of severe infection. The aim of this study was to validate existing pediatric FN CDRs designed to stratify children with cancer at high or low risk of serious infection or medical complication. METHODS Pediatric CDRs suitable for validation were identified from a literature search. Relevant data were extracted from an existing data set of 650 retrospective FN episodes in children with cancer. The sensitivity and specificity of each of the CDR were compared with the derivation studies to assess reproducibility. RESULTS Six CDRs were identified for validation: 2 were designed to predict bacteremia and 4 to predict adverse events. Five CDRs exhibited reproducibility in our cohort. A rule predicting bacteremia had the highest sensitivity (100%; 95% confidence interval (CI): 93%-100%) although poor specificity (17%), with only 15% identified as low risk. For adverse events, the highest sensitivity achieved was 84% (95% CI: 75%-90%), with specificity of 29% and 27% identified as low risk. A rule intended for application after a 24-hour period of inpatient observation yielded a sensitivity of 80% (95% CI: 73-86) and specificity of 46%, with 44% identified as low risk. CONCLUSIONS Five CDRs were reproducible, although not all can be recommended for implementation because of either inadequate sensitivity or failure to identify a clinically meaningful number of low-risk patients. The 24-hour rule arguably exhibits the best balance between sensitivity and specificity in our population.

Abstract
The syndrome of pyrexia of unknown origin (PUO) was first defined in 1961 but remains a clinical challenge for many physicians. Different subgroups with PUO have been suggested, each requiring different investigative strategies: classical, nosocomial, neutropenic and HIV-related. This could be expanded to include the elderly as a fifth group. The causes are broadly divided into four groups: infective, inflammatory, neoplastic and miscellaneous. Increasing early use of positron emission tomography-computed tomography (PET-CT) and the development of new molecular and serological tests for infection have improved diagnostic capability, but up to 50% of patients still have no cause found despite adequate investigations. Reassuringly, the cohort of undiagnosed patients has a good prognosis. In this article we review the possible aetiologies of PUO and present a systematic clinical approach to investigation and management of patients, recommending potential second-line investigations when the aetiology is unclear.

Abstract
Aortic dissection is the most devastating sequela of thoracic aortic disorder. Patients with acute aortic dissection typically manifest as an acute onset of severe chest pain, but occasionally present with atypical symptoms including fever of unknown origin. A total of 50 patients from 41 articles based on a complete literature retrieval were included in this study. More patients had a fever prior to pain. The time to presentation was 40.7 ± 105.6 days, the time to diagnosis was 52.9 ± 110.1 days, and the time to surgery/intervention was 1.8 ± 5.6 days. The patients' temperature on admission was 38.2 ± 0.6 °C and the maximal temperature recorded was 38.8 ± 0.4 °C. Laboratory findings showed increased white blood cell counts, cardiac enzymes, and inflammatory biomarkers. More pronounced laboratory findings of the infectious type than the inflammatory type aortic dissection could be helpful in the differential diagnosis. Half of patients warrant aortic repair with or without valve replacement, less than half of patients were conservatively managed, and a few were interventionally treated or were being followed up. The mortality rate was 9.5 %. Physicians should always bear in mind aortic dissection when patients present with fever of unknown origin particularly in those without chest pain. Laboratory findings may offer inflammatory evidence for the diagnosis. An early diagnosis as well as subsequent treatment is indispensable for patients' outcomes.

Abstract
Fever of unknown origin (FUO) is a rather rare clinical syndrome representing a major diagnostic challenge. The occurrence of more than three febrile attacks with fever-free intervals of variable duration during 6 months of observation has recently been proposed as a subcategory of FUO, Recurrent FUO (RFUO). A substantial number of patients with RFUO have auto-inflammatory genetic fevers, but many patients remain undiagnosed. We hypothesize that this undiagnosed subgroup may be comprised of, at least in part, a number of rare genetic febrile diseases such as Fabry disease. We aimed to identify key features or potential diagnostic clues for Fabry disease as a model of rare genetic febrile diseases causing RFUO, and to develop diagnostic guidelines for RFUO, using Fabry disease as an example of inserting other rare diseases in the existing FUO algorithms. An international panel of specialists in recurrent fevers and rare diseases, including internists, infectious disease specialists, rheumatologists, gastroenterologists, nephrologists, and medical geneticists convened to review the existing diagnostic algorithms, and to suggest recommendations for arriving at accurate diagnoses on the basis of available literature and clinical experience. By combining specific features of rare diseases with other diagnostic considerations, guidelines have been designed to raise awareness and identify rare diseases among other causes of FUO. The proposed guidelines may be useful for the inclusion of rare diseases in the diagnostic algorithms for FUO. A wide spectrum of patients will be needed to validate the algorithm in different clinical settings.

Abstract
Interstitial lung disease (ILD) has rarely been reported as a manifestation of giant cell arteritis (GCA). We herein report a unique case of GCA in a 76-year-old woman who presented with ILD as an initial manifestation of GCA. Ten years before admission, she had been diagnosed with granulomatous ILD of unknown etiology. Corticosteroid therapy induced remission. One year after the cessation of corticosteroid therapy, she was admitted with a persistent fever. After admission, she developed left oculomotor paralysis. Positron emission tomography with 2-deoxy-2-[fluorine-18]fluoro-D-glucose integrated with computed tomography (18F-FDG PET/CT) proved extremely useful in establishing the diagnosis. Our case promotes awareness of GCA as a possible diagnosis for granulomatous ILD with unknown etiology.
