A fever is a rise in body temperature. https://www.who.int/docs/default-source/coronaviruse/situation-reports/2 https://www.moh.gov.sg/news-highlights/details/confirmed-imported-case-o https://www.moh.gov.sg/news-highlights/details/seven-more-confirmed-case World Health Organization. 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. Plasma fractions were isolated from blood samples of COVID-19 patients collected during the acute phase (median post-illness onset, 6 days). Notably, patients with prolonged fever had higher IP-10 and lower IL-1 levels as compared with patients with saddleback fever (Figure 1B). CONCLUSIONS: Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19. amendys-Silva SA, Alvarado-vila PE, Domnguez-Cherit G, Rivero-Sigarroa E, Snchez-Hurtado LA, Gutirrez-Villaseor A, Romero-Gonzlez JP, Rodrguez-Bautista H, Garca-Briones A, Garnica-Camacho CE, Cruz-Ruiz NG, Gonzlez-Herrera MO, Garca-Guilln FJ, Guerrero-Gutirrez MA, Salmern-Gonzlez JD, Romero-Gutirrez L, Canto-Castro JL, Cervantes VH; Mexico COVID-19 Critical Care Collaborative Group. Pediatrics 1975; 55:468. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). The variance between the highest and lowest core temperature in a given day is usually no more than 1 to 1.5C. 10.1038/nature12060 Epub 2020 Oct 21. Plasma immune mediator levels in COVID-19 patients experiencing different fever patterns. Copyright 2023 MIMS Pte Ltd. All rights reserved. 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. 2016 May 20;10(5):e0004575. Treatment of fever in adults usually involves ibuprofen, acetaminophen, or aspirin. On repeat testing, prolonged fever was associated with a drop in hemoglobin and a rise in CRP and LDH (Table 2). Your child may also develop swollen lymph nodes in the neck. 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. Patients who tested positive were not discharged until they had 2 negative PCR tests 24 hours apart [13]. Heart Lung. Blue and red represent low and high concentrations, respectively. Saddleback fever refers to biphasic fever with an initial peak that remits and appears again. Adverse outcomes were hypoxia, intensive care unit (ICU) admission, mechanical ventilation, and mortality. 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). Cytokines were determined with multiplex microbead-based immunoassay for a subgroup of patients. Cytokines were determined with multiplex microbead-based immunoassay for a subgroup of patients. Pung R, Chiew CJ, Young BE, et al. Moreover, cases with prolonged fever also showed significantly higher plasma levels of inflammatory biomarkers such as interleukin (IL)-6 (p<0.01), IL-1RA (p<0.05), and induced protein-10 (IP-10; p<0.001) compared with controls during the early acute disease phase. Demographic and comorbidity data, symptoms and signs, vital signs, and laboratory and radiology results were obtained from electronic medical records. Infect Drug Resist. Prolonged fever is associated with adverse outcomes in dengue viral infection. Corticosteroids for treating mild COVID-19: opening the floodgates of therapeutic misadventure. Ahmed S, Mohammad WW, Hamid F, Akhter A, Afzal RK, Mahmood A. J Coll Physicians Surg Pak. Repeat laboratory investigations and CXR were done for those with prolonged or saddleback fever and collected. 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). Empiric antibiotics or steroids are generally discouraged in patients with fever of unknown origin. 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. 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. 8600 Rockville Pike This site needs JavaScript to work properly. Khalaf M, Alboraie M, Abdel-Gawad M, Abdelmalek M, Abu-Elfatth A, Abdelhamed W, Zaghloul M, ElDeeb R, Abdeltwab D, Abdelghani M, El-Raey F, Aboalam H, Badry A, Tharwat M, Afify S, Elwazzan D, Abdelmohsen AS, Fathy H, Wagih Shaltout S, Hetta HF, Bazeed SE. Lohr JA, Hendley JO. Fever was defined as a temperature of 38.0C. However, there were no significant differences in the admission laboratory values between the control and saddleback fever groups. But normal body temperature can range between 97 F (36.1 C) and 99 F (37.2 C) or more. 2013 Sep 26;7(9):e2412. The 4 cases who were excluded from the primary analysis demonstrated a saddleback pattern of fever that lasted >24 hours. Extreme poverty first: An argument on the equitable distribution of the COVID-19 vaccine in Peru. A dysregulated immune response in COVID-19 has been postulated to lead a deleterious cytokine storm [12]. Comparing the difference between prolonged fever cases and saddleback fever cases, we found an increased IL-1 level and lower IP-10 level on admission. J Clin Med Res. It starts suddenly and lasts 3 to 5 days. In addition, in comparison with other parameters such as respiratory rate, heart rate, or blood pressure, fever is easy to detect and readily identifiable as a risk factor for severe disease. 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). For cytokine profiling, the Mann-Whitney U test was applied to ascertain significant differences in immune mediator levels between patients experiencing different fever patterns. In particular, fever was reported in about 72%98.6% of patients, usually lasting <7 days [4, 710]. Fever, face edema, fatigue, fungal infection, malaise, . Cases with prolonged fever were found to have higher levels of anti-inflammatory IL-1RA, pro-inflammatory IL-6, and chemokine interferon- IP-10 compared with controls (Figure 1B). 2020 Oct 1;180(10):1345-1355. doi: 10.1001/jamainternmed.2020.3539. Available at: Ministry of Health (MOH) Singapore. Teleconferencing is often used to monitor these cases for potential deterioration. 2021 Nov 5;114(8):541-542. doi: 10.1093/qjmed/hcab138. Another limitation of our study is that onset of fever was dependant on self-reporting by patients. The differences in cytokine and chemokine profiles among control patients with fever7 days, patients with prolonged fever, or patients with saddleback fever at the early acute phase of illness suggest that different immunological responses could result in the differences in the clinical phenotype observed. Your body temperature can vary depending . Please check for further notifications by email. Clipboard, Search History, and several other advanced features are temporarily unavailable. 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. eCollection 2017 Summer. 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 ). These patients required prolonged periods of observation and symptomatic treatment. Hospitalized COVID-19 patients with prolonged fever showed more pronounced inflammatory response and were more likely to require ICU admission than cases with saddleback fever or with fever lasting 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. At the initial encounter, testing for common infections should include a complete blood count with differential, electrolyte panel, liver enzymes, urinalysis with culture, blood culture, and chest radiography. Statistical analyses were performed using Stata, version 14 (StataCorp, College Station, TX, USA). Disclaimer. Published by Oxford University Press on behalf of Infectious Diseases Society of America. PMC For cases with saddleback fever, fever recurred at a median (IQR) of 10 (812) days after symptom onset. Copyright 2023 American Academy of Family Physicians. as they fulfilled overlapping criteria for prolonged and saddleback fever. Would you like email updates of new search results? Clinical and laboratory predictive markers for acute dengue infection. Among these patients, 12.7 percent had prolonged fever (median interquartile range [IQR], 10 days) while 9.9 percent had saddleback fever, with fever recurring at a median IQR of 10 days. 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. Duration of fever was prolonged with increased age. Both prolonged (27.8% vs 0.9%; P < .01) and saddleback fever (14.3% vs 0.9%; P = .03) were associated with hypoxia compared with controls. Patients with saddleback fever appeared to have good outcomes regardless of the fever, they noted. A lower IP-10 level is consistent with the finding that saddleback fever cases tend to have better clinical outcomes than prolonged fever cases. Concentrations of 45 immune mediators in plasma were quantified using a 45-plex microbead-based immunoassay. In conclusion, we reported on the prevalence, risk factors, cytokine profiles, and outcomes of patients with COVID-19 who had saddleback or prolonged fever. Depending on clinical clues, this may include liver, lymph node, temporal artery, or bone marrow biopsy. Outcomes of interest were hypoxia, admission to the intensive care unit (ICU), need for mechanical ventilation, and mortality. sharing sensitive information, make sure youre on a federal Fever of unknown origin has been described as a febrile illness (temperature of 101F [38.3C] or higher) for three weeks or longer without an etiology despite a one-week inpatient evaluation. doi: 10.1371/journal.pone.0167025. Epub 2022 Aug 27. Higher respiratory rate, lower SpO2, and lower systolic BP were also associated with saddleback fever compared with the control group. To investigate whether the fever patterns experienced by the patients are due to differences in immune responses, concentrations of 45 immune mediators were profiled. Affiliations, Plasma immune mediator levels in COVID-19 patients experiencing different fever patterns. 2013; 496: 504507. The relationship of these episodes to the long tissue half-life of azithromycin and subsequent prolonged exposure to antigen is presently unknown. 2015 Sep 30;15:399. doi: 10.1186/s12879-015-1141-3. In many cases, no specific cause of the fever is found, 2 . However, there was a proportion of patients from our hospital who displayed 2 patterns of fever: 1 group had fever persisting into the second week of illness, while the second group displayed a saddleback pattern of fever, similar to that previously observed in dengue [11]. FOUR TYPES OF FEVERS - Read online for free. Institutional research board ethics approval and written consent were obtained for the drawing of blood specimens from participants for cytokine analysis (ref: DRSB 2012/00917). Patients with prolonged fever are more likely to develop hypoxia and have a more pronounced inflammatory response in comparison with those in the saddleback fever group, which is also reflected in the different cytokine profiles between the 2 groups. eCollection 2022. Epub 2022 Aug 11. . Like RA, rheumatic fever affects the joints. Concentrations of 45 immune mediators in plasma were quantified using a 45-plex microbead-based immunoassay. 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. Statistical analyses were performed with the Mann-Whitney. This is an Open Access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs licence (. The author(s) received no specific funding for this work. The results of these microbiological investigations were also collected and analyzed. Two remained in the general ward throughout their stay without any complications, while 2 were admitted to the ICU, 1 of whom died from acute respiratory distress syndrome. eCollection 2016. 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). but the rest of the symptoms did not have a difference between the 2 serotypes. In hypoxic conditions, it can trigger the expression of chemokines that attract neutrophils and monocytes to the ischemic tissue [31]. Available at: Wang D, Hu B, Hu C, et al. Two of these patients were admitted to the ICU, which may suggest another phenotype of patients who are at higher risk of adverse outcomes. Our cohort only had 1 mortality, and this may be reflective of the overall low mortality rate in Singapore. 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. Emadi A, Chua JV, Talwani R, Bentzen SM, Baddley J. Clinico-laboratory spectrum of dengue viral infection and risk factors associated with dengue hemorrhagic fever: a retrospective study. Prolonged fever was defined as fever lasting more than 7 days. For most people, a temperature of 98.6 F or 37 C is baseline. The mean duration of symptoms and signs before diagnosis (28.4 13.2 versus 45.0 30.8 days; P < 0.05), . 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. PLoS Negl Trop Dis. Coronavirus disease 2019 (COVID-19) situation report101.2020. Clinical characteristics of 138 hospitalized patients with 2019 novel coronavirus-infected pneumonia in Wuhan, China. 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. 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. Clinicians should perform a comprehensive history and examination to look for potentially diagnostic clues to guide the initial evaluation. 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. Nature. In patients with saddleback fever, higher levels of IL-1, IL-21, IL-22, and SDF-1 were observed compared with control patients. Prolonged fever of unknown origin in children. This phenomenon is also observed in other viral fevers, like dengue virus [27] and thrombocytopenia syndrome virus [28, 29], where patients with more severe illness have higher serum levels of IP-10. A fever is a body temperature of 100.4 F or greater. One limitation of the study is the small sample size of our cohort. 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. 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. The most common subgroups in the differential are infection, malignancy, noninfectious inflammatory diseases, and miscellaneous. Chan SY, Tsai YF, Yen MY, Yu WR, Hung CC, Kuo TL, Chen CC, Yen YF, Huang SH, Huang TC, Huang SJ. Patients with saddleback fever appeared to have good outcomes regardless of the 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- 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). It's usually a sign of infection. Blue and red represent low and high concentrations, respectively. Despite the progression on CXR in over one-third of cases with saddleback fever, these cases tend to do well. 8600 Rockville Pike Ministry of Health Singapore. ELIZABETH C. HERSCH, COL, MC, USA, AND C. ROBERT, OH, LTC, MC, USA. 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. 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. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Disclaimer. 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. Fever is a nonspecific symptom that may be caused by infectious and noninfectious conditions, including malignancies, systemic rheumatic diseases, and drug reactions. 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. 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. Plasma fractions were isolated from blood samples of COVID-19 patients collected during the acute phase (median post-illness onset, 6 days). The results of this study can be used to optimize placement of patients with COVID-19. Prevalence and Predictors of Persistent Symptoms After Clearance of SARS-CoV-2 Infection: A Multicenter Study from Egypt. COVID-19 generally presents as an acute respiratory illness, with fever, fatigue, and dry cough being commonly reported symptoms [46]. 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. Flu is caused by influenza viruses only, whereas the common cold can be caused by a number of different viruses, including rhinoviruses, parainfluenza, and seasonal coronaviruses. Saddleback fever cases were also found to have higher pro-inflammatory IL-1, T-cell-activating mediators IL-21 and IL-22, and chemokine stromal cellderived factor 1 (SDF-1) compared with controls (Figure 1B). Cavalli G, De Luca G, Campochiaro C, et al. Statistical data analysis on the types of fevers Although there are more than 200 diseases in the differential diagnosis, most cases in adults are limited to several dozen possible causes. Another 4 patients were excluded from the primary analysis as they had a saddleback pattern of fever that lasted >24 hours; 12.7% (18/142) of cases had prolonged fever and another 9.9% (14/142) had saddleback fever. Biphasic Zika Illness With Rash and Joint Pain. Patients with saddleback fever appeared to have good outcomes regardless of the fever. Some children also may have a sore throat, runny nose or cough along with or before the fever. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are nonspecific acute-phase reactants that are routinely part of the evaluation of febrile patients.5,28 An extremely elevated ESR (100 mm per hour or greater) suggests etiologies such as abdominal or pelvic abscess, osteomyelitis, and endocarditis. A Two-Year Review on Epidemiology and Clinical Characteristics of Dengue Deaths in Malaysia, 2013-2014. Prolonged fever of unknown origin: a record of experiences with 54 childhood patients. Interestingly, there are also higher plasma levels of IL-1RA in patients with prolonged fever compared with control patients. Similar fever patterns are observed in COVID-19 with unclear significance. 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. Roseola symptoms might include: Fever. Those with prolonged fever had a median duration of fever (interquartile range [IQR]) of 10 (9-11) days for prolonged fever cases, while fever recurred at a median (IQR) of 10 (8-12) days for those with saddleback fever. No overall differences in safety or effectiveness . Both prolonged fever and saddleback fever were not significantly associated with mechanical ventilation as compared with the control group (Table 1).
