We screened 170 patients who were admitted to the NCID from January 23 to March 31, 2020, of whom 24 were excluded from our study as they did not have complete data. https://www.moh.gov.sg/content/moh_web/home/Publications/Reports/2006/co http://www.who.int/tdr/publications/documents/dengue-swg.pdf, Brady OJ, Gething PW, Bhatt S, Messina JP, Brownstein JS, Joen AG, et al.

Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19. Lancet 2020; 395:497506. This suggests that in patients with prolonged fever, close monitoring for deterioration should be instituted, while patients with saddleback fever who remain well and do not require supplemental oxygenation are unlikely to require close monitoring in the hospital, explained Ng and co-authors. In multiple studies, procalcitonin has been shown to have a specificity ranging from 70% to 98%, with a higher specificity for bacterial infection than other markers.28,31,32 It may be helpful in distinguishing between fevers with a bacterial cause vs. noninfectious inflammatory diseases, but its role in the workup of FUO is currently undefined.28,32, If the diagnosis remains elusive, tests targeting malignancies and noninfectious inflammatory diseases should be considered. doi: 10.1093/ofid/ofx133. Cases with prolonged fever were more likely to have hypoxia (27.8% vs 0.9%; P<.01) and ICU admission (11.1% vs 0.9%; P=.05) compared with cases in the control group (Table 1).

To investigate whether the fever patterns experienced by the patients are due to differences in immune responses, concentrations of 45 immune mediators were profiled. Prolonged fever (fever > 7 days duration) was present in 572 (20.1%) of patients. See permissionsforcopyrightquestions and/or permission requests. Fever was defined as a temperature of 38.0C or higher.

FOIA 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.

In general, fever is defined as a temperature > 38C (100.4F). Influenza (flu) and the common cold are both contagious respiratory illnesses, but they are caused by different viruses.

Concentrations of 45 immune mediators in plasma were quantified using a 45-plex microbead-based immunoassay. Bethesda, MD 20894, Web Policies Figure 1 outlines a diagnostic approach to patients with prolonged febrile illness and FUO.1,2,47,1520,23,27, Hospitalization may be considered at any time during the evaluation, especially if the patient exhibits signs of a critical illness. 10.1038/nature12060 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.

The clinical features of classic KD are shown in Table 1. COVID-19; cytokines; fever; prolonged; saddleback. A total of 2843 polymerase-chain reaction (PCR) confirmed dengue patients admitted to Tan Tock Seng Hospital from 2004 to 2008 were included in the study. Saddleback fever was present in 165 (5.8%). Emadi A, Chua JV, Talwani R, Bentzen SM, Baddley J. Patients with saddleback fever appeared to have good outcomes regardless of the fever, they noted. Copyright 2014 by the American Academy of Family Physicians. Meanwhile, the levels of IP-10 in patients with saddleback fever was lower than those with prolonged fever (p<0.001) at a level almost matching that in controls. Testing for antinuclear antibodies, rheumatoid factor, human immunodeficiency virus, Epstein-Barr virus, cytomegalovirus, purified protein derivative (or interferon-gamma release assay), and antineutrophil cytoplasmic antibodies, as well as measurement of the creatine kinase level, can suggest other infectious sources and common noninfectious inflammatory disease etiologies, such as systemic lupus erythematosus, rheumatoid arthritis, and vasculitides. There was no difference in types of diagnoses for those who met the strict 1991 definition compared with those who received a diagnosis in less than three weeks.10 Therefore, FUO may be assumed when no reasonable diagnosis is reached after an appropriate inpatient or outpatient investigation.2,6,1017 Table 1 compares the evolution of the definition of FUO.2,3,6,7,1017, Other subtypes of FUO are nosocomial, neutropenic, and human immunodeficiency virusassociated.7 These subtypes have different approaches to evaluation and are beyond the scope of this article.17, The etiologies of FUO have changed over time because of shifting disease patterns and new diagnostic techniques.14 There are more than 200 diseases in the differential diagnosis.4,15,17 In multiple case series, however, the etiology of FUO is limited to several dozen causes, and patients often have an atypical presentation of a common disease.2,6,18. Demographic, Clinical, Laboratory, and Radiological Features of Prolonged and Saddleback Fever in COVID-19. A lower IP-10 level is consistent with the finding that saddleback fever cases tend to have better clinical outcomes than prolonged fever cases. 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. B, Comparison of immune mediator levels in patients with prolonged fever (n=11), patients with saddleback fever (n=8), and patients with fever that lasted 7 days (control; n=56). Epub 2022 Aug 11. Patient samples that are not detectable are presented as the value of logarithm transformation of limit of quantification (LOQ), indicated by the blue dotted line. Mucosal bleeding, anorexia, diarrhea, abdominal pain, nausea or vomiting, lethargy, rash, clinical fluid accumulation, hepatomegaly, nosocomial infection, leukopenia, higher neutrophil count, higher hematocrit, higher alanine transaminase (ALT) and aspartate transaminase (AST), higher creatinine, lower protein and prolonged activated partial thromboplastin time (APTT) were significantly associated with prolonged fever but not platelet count or prothrombin time (PT). Cases without prolonged or saddleback fever were included as controls. PMC In contrast, cases with saddleback fever showed no significant change upon repeating their laboratory tests. 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. Recommendations of the Scientific Working Group on Dengue. Ministry of Health Singapore. This content is owned by the AAFP. Bookshelf 2 A diagnosis of classic KD is made in patients with prolonged fever (five or more days) and four or more of the following principal . Those with prolonged fever had a median duration of fever for 10 days (IQR 9-11 days) for prolonged fever cases, while fever recurred at a median of 10 days (IQR 8-12 days) for those with saddleback fever. 2021 Jan-Feb;50(1):28-32. doi: 10.1016/j.hrtlng.2020.10.013. 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. Chan SY, Tsai YF, Yen MY, Yu WR, Hung CC, Kuo TL, Chen CC, Yen YF, Huang SH, Huang TC, Huang SJ. Viruses, bacteria, fungi, and parasites can cause infections. In addition, as these patients with saddleback fever tend to do well, there is also no need for repeat laboratory testing or CXR, as the results are unlikely to change management or clinical outcomes. Financial support. Fever of unknown origin (FUO) in adults is one of the most vexing clinical conditions for clinicians and patients. Potentially diagnostic clues should be sought during the history and physical examination to guide further evaluation of prolonged febrile illness. Available at: Wang D, Hu B, Hu C, et al. 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.
