Data Sources: A PubMed search was completed using the key terms fever of unknown origin, FUO, pyrexia of unknown origin, and inflammatory markers. One case with prolonged fever had concomitant infection with ventilator-associated pneumonia, with Klebsiella pneumoniae grown from his endotracheal aspirate on day 8 of ICU admission (day 15 of illness). ; Singapore 2019 Novel Coronavirus Outbreak Research Team. Common causes of FUO are listed in Table 2.6,1523 Typical subgroups used in the differential for classical FUO are infection (20% to 40%), malignancy (20% to 30%), noninfectious inflammatory diseases (10% to 30%), miscellaneous (10% to 20%), and undiagnosed (up to 50%).1,46,1418,2224 Noninfectious inflammatory diseases commonly include connective tissue diseases, vasculitides, and granulomatous diseases.16,17 In developed countries, the noninfectious inflammatory diseases and undiagnosed groups comprise a higher proportion of FUO cases.5,10,15,17 Underdeveloped countries have higher rates of infection and neoplasm.6,24 Drug fever is implicated in 1% to 3% of FUO cases16 (Table 320,21,25,26 ). Your comment will be reviewed and published at the journal's discretion. Cases without prolonged or saddleback fever were included as controls. Ying-Hao P, Yuan-Yuan G, Hai-Dong Z, Qiu-Hua C, Xue-Ran G, Hai-Qi Z, Hua J. Seven more confirmed cases of novel coronavirus infection in Singapore. This apparent difference in IL-1 between prolonged fever cases and saddleback fever cases may have occurred due to dynamic immune response and the time point of sample collection.

FOIA 2013; 496: 504507. We conducted a hospital-based case-control study of patients admitted for COVID-19 with prolonged fever (fever >7 days) and saddleback fever (recurrence of fever, lasting <24 hours, after defervescence beyond day 7 of illness). When compared with controls, both prolonged and saddleback fever were associated with hypoxia, with the highest rate seen in cases with prolonged fever (27.8 percent and 14.3 percent vs 0.9 percent for prolonged and saddleback fever vs control, respectively; p<0.01 and p=0.03 for each respective comparison). Epub 2020 Oct 21. Adverse outcomes were hypoxia, intensive care unit (ICU) admission, mechanical ventilation, and mortality. But there are some important differences. Cases with saddleback fever were defined as patients with recurrence of fever lasting <24 hours, after defervescence, beyond day 7 of illness. No overall differences in safety or effectiveness . Nature. Prolonged fever was defined as fever lasting more than 7 days. Factors associated with dengue shock syndrome: a systematic review and meta-analysis. Immune mediator levels in Triton X-100 (1%; Sigma Aldrich) inactivated plasma from a subset of patients in all 3 groups were measured using Cytokine/Chemokine/Growth Factor 45-plex Human ProcartaPlex Panel 1 (ThermoFisher Scientific), in accordance with the manufacturers instructions. The Significance of Prolonged and Saddleback Fever in Hospitalised Adult Dengue. McClung HJ. Cases with prolonged fever were defined as patients with fever lasting >7 days. For cases with prolonged fever, investigations were repeated beyond day 7 of illness, and for cases with saddleback fever, investigations were repeated at point of fever recurrence. Cases who were already on supplemental oxygen or were already in the ICU at the time of satisfying criteria for prolonged or saddleback fever were excluded from the analysis. While it has been reported that complications of COVID-19 occur in the second week of illness, the significance of these 2 patterns of fever with regards to the development of complications is unknown [4]. In health, body temperature is regulated around a set point of 37 1C, and a circadian temperature rhythm exists in which the highest temperature of each day occurs around 6 p.m. Although there are more than 200 diseases in the differential diagnosis, most cases in adults are limited to several dozen possible causes. Untreated typhoid fever may progress to delirium, obtundation, intestinal hemorrhage, bowel. This study was funded by the National Medical Research Council COVID-19 Research Fund (COVID19RF-001) and Agency for Science, Technology and Research (A*STAR) COVID-19 Research funding (H/20/04/g1/006) provided to the Singapore Immunology Network by the Biomedical Research Council (BMRC), A*STAR. In hypoxic conditions, it can trigger the expression of chemokines that attract neutrophils and monocytes to the ischemic tissue [31]. Abbreviations: ALT, alanine aminotransferase; AST, aspartate aminotransferase; BP, blood pressure; CRP, C-reactive protein; LDH, lactate dehydrogenase. In this study, we aim to examine the characteristics of patients who developed these patterns of fever and their correlation to cytokine levels, as well as the association with adverse outcomes in COVID-19. Concentrations of 45 immune mediators in plasma were quantified using a 45-plex microbead-based immunoassay. Disclaimer. Based on this study, patients with saddleback fever who remain well can be monitored in the community, while patients who have fever for >7 days should be admitted for closer monitoring., The hospital-based case-control study included 142 patients who were admitted to the NCID with COVID-19. Rheumatic fever mostly affects children aged 5-15 years, but it is rare in adults and children aged under 3 years. Home or community isolation facilities are commonly used globally for less sick patients such that hospital beds are free up to cater for sicker patients. Statistical analyses were performed using Stata, version 14 (StataCorp, College Station, TX, USA). 40-year-old woman fever rash arthralgia Dx? Infections predominate early in FUO diagnoses, and the longer FUO remains undiagnosed, the less likely it is caused by an infection.27 After infections, the etiology of FUO transitions to noninfectious inflammatory diseases and malignancies, which can guide subsequent testing. In general, fever is defined as a temperature > 38C (100.4F). Clipboard, Search History, and several other advanced features are temporarily unavailable. Angela Chow Li Ping, Brenda Sze Peng Ang, Chen Seong Wong, Cheng Chuan Lee, Ding Ying, Jun-Yang Tay, Kalisvar Marimuthu, Lawrence Soon U.

Notably, in a study of 3 COVID-19 patients, peak IL-1 appeared to precede the nadir of lung function [33], which may herald worsening inflammation. The reference values for the normal ranges of laboratory tests were in accordance with those used by the hospital laboratory. as they fulfilled overlapping criteria for prolonged and saddleback fever. Cavalli G, De Luca G, Campochiaro C, et al. When compared with controls, both prolonged and saddleback fever were associated with hypoxia, with the highest rate seen in cases with prolonged fever (27.8 percent and 14.3 percent vs 0.9 percent for prolonged and saddleback fever vs control, respectively; p<0.01 and p=0.03 for each respective comparison). The presence of prolonged or saddleback fever in dengue patients should therefore prompt detailed evaluation for complications of dengue, as well as early investigation to evaluate for development of nosocomial infection. Published by Oxford University Press on behalf of Infectious Diseases Society of America. A lower IP-10 level is consistent with the finding that saddleback fever cases tend to have better clinical outcomes than prolonged fever cases. Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19. This site needs JavaScript to work properly. A total of 142 patients were included in the study; 12.7% (18/142) of cases had prolonged fever, and 9.9% (14/142) had saddleback fever. The median age was 34 years of age (5 th - 95 th percentile: 17-59) and males comprised 1971 (69.3%) of study sub- PLoS Negl Trop Dis 2012; 6(8): e1760 10.1371/journal.pntd.0001760 2021 Nov 5;114(8):541-542. doi: 10.1093/qjmed/hcab138. Plasma immune mediator levels in COVID-19 patients experiencing different fever patterns. Ahmed S, Mohammad WW, Hamid F, Akhter A, Afzal RK, Mahmood A. J Coll Physicians Surg Pak. 2017 Jun 22;4(3):ofx133. Prolonged fever is associated with adverse outcomes in dengue viral infection. Repeat CXR was not performed for cases in the control group and 1 case of saddleback fever. Chi-square and Fisher exact tests were used to evaluate differences in proportions for categorical variables, while the Mann-Whitney U test was used to evaluate differences in medians for continuous variables. [The] lower IP-10 level [with saddleback fever] is consistent with the finding that saddleback fever cases tend to have better clinical outcomes than prolonged fever cases, they noted. official website and that any information you provide is encrypted Members of the National Centre for Infectious Diseases COVID-19 Outbreak Research Team. Qiu H, Wu J, Hong L, Luo Y, Song Q, Chen D. Arend WP, Malyak M, Guthridge CJ, Gabay C. Essayan DM, Fox CC, Levi-Schaffer F, Alam R, Rosenwasser LJ. Patients who tested positive were not discharged until they had 2 negative PCR tests 24 hours apart [13]. Dengue fever is an acute febrile illness with a duration of 2-12 days. Conclusions: Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19. History and physical examination alone are often sufficient to diagnose uncomplicated infectious causes of fever . There were no deaths in our study. It's usually a sign of infection. Several diagnostic algorithms have been suggested for FUO, but few are supported by evidence from prospective studies.17 Region-specific serologic tests, more advanced radiologic studies, and more invasive diagnostic procedures can be guided by potentially diagnostic clues. ELIZABETH C. HERSCH, COL, MC, USA, AND C. ROBERT, OH, LTC, MC, USA. A comprehensive history and physical examination should be performed if there are no localizing signs and symptoms in patients with prolonged febrile illness. Cytokines were determined with multiplex View PDF Save to Library There were no significant changes in laboratory findings when repeated at the point of fever, except for a rise in platelet and lymphocyte counts (Table 2). A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. In this study, saddleback fever was defined as temperature >37.5C with defervescence of at least one day, followed by a second peak lasting at least one day. Additional microbiological investigations, such as blood and urine cultures, influenza and respiratory viral multiplex PCR, dengue NS1 and serology, were ordered at the discretion of the primary treating clinician. Biphasic Zika Illness With Rash and Joint Pain. In addition, as these patients with saddleback fever tend to do well, there is also no need for repeat laboratory testing or chest X-ray, as the results are unlikely to change management or clinical outcomes, they said. Empiric antibiotics or steroids are generally discouraged in patients with fever of unknown origin. 2016 Dec 9;11(12):e0167025. doi: 10.1371/journal.pone.0167025. Coronavirus disease 2019 (COVID-19) situation report101. 2015 Sep 30;15:399. doi: 10.1186/s12879-015-1141-3. 2022 Aug;14(8):321-326. doi: 10.14740/jocmr4791. Elevated lactate dehydrogenase levels can be indicative of infectious and malignant causes of FUO, including malaria, lymphoma, and leukemia.15,21 Measurement of ferritin levels may also be helpful.33 An elevated ferritin level in prolonged febrile illness may indicate malignancy (especially myeloproliferative disorders) and other noninfectious inflammatory diseases, such as systemic lupus erythematosus or temporal arteritis.21,33 One study established a ferritin level of 561 ng per mL (1,261 pmol per L) as the optimal cutoff value to predict that FUO was due to a noninfectious cause.22 Extreme elevation of ferritin levels (greater than 1,000 ng per mL [2,247 pmol per L]) can point to adult Still disease.34 Infection is the most common reason ESR is extremely elevated, but if there is no evidence of infectious causes, clinicians should consider malignancy, renal disease, and inflammatory disorders if the ESR is 100 mm per hour or greater.29. 2013 Jul;23(7):463-7. Available at: Ministry of Health (MOH) Singapore. Lohr JA, Hendley JO. There was progression of infiltrates on the CXR for 72.2% (13/18) of cases with prolonged fever and 38.5% (5/13) in those with saddleback fever. Compared with prolonged fever, saddleback fever did not show many significant associations except for diarrhea, abdominal pain, clinical fluid accumulation, hematocrit and platelet change, and lower systolic blood pressure. Background: Pizzo PA, Lovejoy FH Jr, Smith DH. Fever was defined as a temperature of 38.0C. Like RA, rheumatic fever affects the joints. PMC This study aims to examine the prevalence of prolonged and saddleback fever in dengue as well as their associations with dengue severity. Differences Between Prolonged Fever and Nonprolonged Fever Groups. The mean duration of symptoms and signs before diagnosis (28.4 13.2 versus 45.0 30.8 days; P < 0.05), . -. Although prolonged and saddleback fever have been reported in dengue fever, there are no specific studies on their significance in dengue. The differences in cytokine and chemokine profiles among [the three groups] suggest that different immunological responses could result in the differences in the clinical phenotype observed, said Ng and co-authors. When there are no clear localizing signs or symptoms, clinicians should expand on the patient's symptoms and historical information, looking for potentially diagnostic clues to guide the evaluation (Table 4).1720,25,27 This is a continuous, iterative process.1921 Potentially diagnostic clues lead to a diagnosis in 62% of patients, although clues can be misleading because they are found in 97% of patients.1517, If no potentially diagnostic clues are found, a minimum diagnostic workup should be performed. In conclusion, we reported on the prevalence, risk factors, cytokine profiles, and outcomes of patients with COVID-19 who had saddleback or prolonged fever. Some children also may have a sore throat, runny nose or cough along with or before the fever. Methods We conducted a hospital-based case-control study of patients admitted for COVID-19 with prolonged fever (fever >7 days) and saddleback fever (recurrence of fever, lasting <24 hours, after defervescence beyond day 7 of illness). The results of these microbiological investigations were also collected and analyzed. Patients with prolonged fever had higher induced protein-10 and lower interleukin-1 levels compared with those with saddleback fever at the early acute phase of disease. Please enable it to take advantage of the complete set of features! One limitation of the study is the small sample size of our cohort.

Conflicts that the editors consider relevant to the content of the manuscript have been disclosed. The site is secure. Importantly, upregulation of the IL-1 pathway on monocytes can increase prostaglandin E2 expression and drive fever [32]. The clinical features of classic KD are shown in Table 1. In particular, fever was reported in about 72%98.6% of patients, usually lasting <7 days [4, 710]. The search included reviews, case series, meta-analyses, and randomized controlled trials. Repeat laboratory investigations and CXR were done for those with prolonged or saddleback fever and collected. Infect Drug Resist. We wish to thank members of the Singapore Immunology Network Wilson How, Norman Leo Fernandez, Olaf Rtzschke, and Bernett Lee for their assistance with the multiplex microbead-based immunoassays and data analyses. However, this view of fever is merely an oversimplification as a growing body of evidence now suggests that fever represents a complex adaptive response of the host to various immune challenges whether infectious or non-infectious. Published by Oxford University Press on behalf of Infectious Diseases Society of America. Prolonged fever of unknown origin in children. Epub 2022 Aug 11. Singapore reported its first imported case of COVID-19 in a traveler from Wuhan on January 23, 2020, followed by its first locally transmitted case on February 7, 2020 [2, 3]. Confirmed imported case of novel coronavirus infection in Singapore; multi-ministry taskforce ramps up precautionary measures. 2016 May 20;10(5):e0004575. and transmitted securely. To our knowledge, this is the first study to examine the association between the patterns of fever and outcomes in COVID-19. Prolonged fever in children: review of 100 cases. Unauthorized use of these marks is strictly prohibited. A fever is a rise in your body temperature. Demographics were similar across the 3 groups (Table 1); 7.0% (10/142) of patients had comorbidities, such as diabetes (n=4), ischemic heart disease (n=3), and asthma (n=3). Clinical characteristics and analysis of risk factors for disease progression of patients with SARS-CoV-2 Omicron variant infection: A retrospective study of 25207 cases in a Fangcang hospital. JAMA 2020; 323(11):10619. In many cases, no specific cause of the fever is found, 2 .

Edupuganti S, Natrajan MS, Rouphael N, Lai L, Xu Y, Feldhammer M, Hill C, Patel SM, Johnson SJ, Bower M, Gorchakov R, Berry R, Murray KO, Mulligan MJ. Because there are no guidelines to the approach of the febrile patient, most evaluation recommendations are based on expert opinion.17 On initial presentation, most clinicians perform a history and physical examination in pursuit of an infection. This study demonstrates that prolonged fever may be associated with various warning signs and more severe forms of dengue (SD, DSS, DHF), while saddleback fever showed associations with DHF. The levels of other immune mediators measured were not significantly different between groups. The relationship of these episodes to the long tissue half-life of azithromycin and subsequent prolonged exposure to antigen is presently unknown. Patients were categorized as having prolonged fever (lasting >7 days), saddleback fever (defined as recurrent fever which lasts for <24 hours, after defervescence beyond day 7 of illness), or controls if their fever was 7 days. 20 ; 20 ( 1 ):75. doi: 10.1186/1423-0127-20-75 Mohammad WW, Hamid F, a!
