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. Print 2021 Jan-Mar. The search included reviews, case series, meta-analyses, and randomized controlled trials. Outcomes of COVID-19 Among High-Risk Individuals: A Study Comparing Febrile and Afebrile Presentation. The mean duration of symptoms and signs before diagnosis (28.4 13.2 versus 45.0 30.8 days; P < 0.05), . 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. 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. Outcomes of interest were hypoxia, admission to the intensive care unit (ICU), need for mechanical ventilation, and mortality. We also excluded 4 patients whose fever pattern did not fulfill the case definition for prolonged or saddleback fever. PLoS One. Similar fever patterns are observed in COVID-19 with unclear significance. 2016 Dec 9;11(12):e0167025. It's usually a sign of infection. Over- or under-reporting of the onset of fever before admission could affect the number of patients found to have prolonged or saddleback fever. Higher respiratory rate, lower SpO2, and lower systolic BP were also associated with saddleback fever compared with the control group. Pediatrics 1975; 55:468. The site is secure. Available at: Ministry of Health (MOH) Singapore. Cases with prolonged fever were also more likely to require ICU admission compared with controls (11.1% vs 0.9%; P=.05). Young BE, Ong SWX, Kalimuddin S, et al. Fever is a nonspecific symptom that may be caused by infectious and noninfectious conditions, including malignancies, systemic rheumatic diseases, and drug reactions. This site needs JavaScript to work properly. If noninvasive diagnostic tests are unrevealing, then the invasive test of choice is a tissue biopsy because of the relatively high diagnostic yield. Unable to load your collection due to an error, Unable to load your delegates due to an error, Collaborators, Notably, patients with prolonged fever had higher IP-10 and lower IL-1 levels as compared with patients with saddleback fever (Figure 1B). Coronavirus disease 2019 (COVID-19) situation report101. 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. 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. Conflicts that the editors consider relevant to the content of the manuscript have been disclosed. Treatment. 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). These patients required prolonged periods of observation and symptomatic treatment. Epub 2022 Aug 11. Self-recorded temperature monitoring for COVID-19 patients at home or community isolation facilities can be used to triage patients who need admission to the hospital. None of the 3 patients who entered the ICU had culture-proven nosocomial infections, suggesting that the fevers observed in the ICU were likely related to COVID-19 infection. In one study of patients with FUO, chest and abdominal CT had high sensitivity (82% and 92%, respectively) and were recommended if the initial evaluation was unrevealing.15 CT specificity ranged from 60% to 70%, consistent with other case series.15,16 Echocardiography is recommended if there are clinical indications of endocarditis.5,20 Venous Doppler ultrasonography is indicated for suspected thromboembolism.20 Magnetic resonance imaging of the aortic arch and great vessels of the neck was shown to be helpful when vasculitis was suspected.36, Nuclear imaging studies are noninvasive, image the whole body, and can localize a potential infectious or inflammatory cause for FUO.5,14,19,3740 Recently, 18F fluorodeoxyglucose positron emission tomography technology has been evaluated for guiding further invasive testing, especially in patients who have an elevated ESR or CRP level.14,37 The 18F fluorodeoxyglucose is taken up by inflammatory and cancer cells because of their high rate of glucolysis.14,18,37 Several studies examining this method in patients with FUO found diagnostic yields ranging from 16% to 69%,15,37,38 with a high positive predictive value (93%) and negative predictive value (100%).39,40 A hybrid of CT and 18F fluorodeoxyglucose positron emission tomography has a higher diagnostic yield (sensitivity of 56% to 100%; specificity of 75% to 81%18). Those with prolonged fever had a median duration of fever (interquartile range [IQR]) of 10 (911) days for prolonged fever cases, while fever recurred at a median (IQR) of 10 (812) days for those with saddleback fever. is funded by the National Medical Research Council (NMRC/Fellowship/0056/2018). 40-year-old woman fever rash arthralgia Dx? 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. For most people, a temperature of 98.6 F or 37 C is baseline. PMC sharing sensitive information, make sure youre on a federal eCollection 2022 Jul. Open Forum Infect Dis. Heart Lung. While both prolonged and saddleback fever showed an association with hypoxia, only prolonged fever was associated with ICU admission.

FOIA Refining the global spatial limits of dengue virus transmission by evidence-based consensus. Adverse outcomes were hypoxia, intensive care unit (ICU) admission, mechanical ventilation, and mortality. Prolonged fever lasting more than 7 days after illness onset can help physicians identify patients at high risk for adverse outcomes from COVID-19, according to a study. Epub 2020 Oct 21. Unauthorized use of these marks is strictly prohibited. Treatment of fever in adults usually involves ibuprofen, acetaminophen, or aspirin. 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. "It is extremely difficult to tell the difference," explains Dr. Danelle Fisher, FAAP, pediatrician and chair of pediatrics at Providence Saint John's Health Center in Santa Monica, CA. Background: One review found that noninvasive procedures led to most of the diagnoses, whereas of the invasive procedures, biopsies had the highest diagnostic yield.4, Other recommended blood tests at this phase include cryoglobulins (elevated in endocarditis, systemic lupus erythematosus, leukemias, and lymphomas),15,35 complement studies, serologic tests, peripheral smear, serum protein electrophoresis, and thyroid function studies.

Oxford University Press is a department of the University of Oxford. Differences Between Prolonged Fever and Nonprolonged Fever Groups. -. 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. Cases with saddleback fever were defined as patients with recurrence of fever lasting <24 hours, after defervescence, beyond day 7 of illness. In patients with a prolonged febrile illness, a minimum diagnostic workup should be performed before classifying the disease process as a fever of unknown origin. Some children also may have a sore throat, runny nose or cough along with or before the fever. Unauthorized use of these marks is strictly prohibited.

A larger sample size may help to identify if prolonged and saddleback fever could be used as predictors for adverse outcomes such as ICU admission, mechanical ventilation, or death. All authors: no reported conflicts of interest. However, as the number of patients with prolonged fever requiring ICU admission is small in this cohort, further studies should be done to prove this correlation. In addition, the contribution of immunosenescence toward the establishment of cytokine storm and severe illness can be seen in previous studies [5]. In addition to their pro-inflammatory properties, both IL-6 and IP-10 have been reported to be associated with disease severity and ICU admission in COVID-19 [18, 19] .

Patients with saddleback fever appeared to have good outcomes regardless of the fever. 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. Both prolonged fever and saddleback fever were not significantly associated with mechanical ventilation as compared with the control group (Table 1). But normal body temperature can range between 97 F (36.1 C) and 99 F (37.2 C) or more.

The higher levels of IL-1 could initiate the first occurrence of fever, while the pro-inflammatory cytokines IL-21 and IL-22 mediate the activation of T cells and M1 macrophages [25, 26], which drive the recurrence of fever in saddleback fever cases. 2013 Sep 26;7(9):e2412. Interestingly, there are also higher plasma levels of IL-1RA in patients with prolonged fever compared with control patients. Two of these patients were admitted to the ICU, which may suggest another phenotype of patients who are at higher risk of adverse outcomes. 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). Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19. Empiric antibiotics or steroids are generally discouraged in patients with fever of unknown origin. Trials. doi: 10.1371/journal.pntd.0002412.
