difference between prolonged fever and saddleback fever

Emadi A, Chua JV, Talwani R, Bentzen SM, Baddley J. Potential conflicts of interest. 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 conclusion, we reported on the prevalence, risk factors, cytokine profiles, and outcomes of patients with COVID-19 who had saddleback or prolonged fever. Copyright 2014 by the American Academy of Family Physicians. 2022 May 20;15:2575-2587. doi: 10.2147/IDR.S355064. PLoS Negl Trop Dis. At the time of writing, the mortality rate from COVID-19 in Singapore was 0.09% [36]. It's usually a sign of infection. Confirmed imported case of novel coronavirus infection in Singapore; multi-ministry taskforce ramps up precautionary measures. Background: Europe PMC is an archive of life sciences journal literature. Outcomes of interest were hypoxia, admission to the intensive care unit (ICU), need for mechanical ventilation, and mortality. 2013; 496: 504507. 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. Blue and red represent low and high concentrations, respectively. 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. Biphasic Zika Illness With Rash and Joint Pain. Nevertheless, as patients in the ICU are at higher risk of nosocomial infections, due diligence should be done to exclude other causes of fever [17]. Statistical analyses were performed using GraphPad Prism, version 8. Antibiotics usually aren't prescribed just because a child has a fever that is lasting a long time. 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. Hypoxia was defined as requirement for supplemental oxygen. Corticosteroids for treating mild COVID-19: opening the floodgates of therapeutic misadventure. eCollection 2022. Clipboard, Search History, and several other advanced features are temporarily unavailable. Clinico-laboratory spectrum of dengue viral infection and risk factors associated with dengue hemorrhagic fever: a retrospective study. Careers. Although there are more than 200 diseases in the differential diagnosis, most cases in adults are limited to several dozen possible causes. eCollection 2022 Jul. Patients with saddleback fever appeared to have good outcomes regardless of the fever. But there are some important differences. Higher respiratory rate, lower SpO2, and lower systolic BP were also associated with saddleback fever compared with the control group. 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. 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). Abbreviations: ALT, alanine aminotransferase; AST, aspartate aminotransferase; BP, blood pressure; CRP, C-reactive protein; LDH, lactate dehydrogenase. Geneva: World Health Organization, Special Programme for Research and Training in Tropical Diseases, Geneva: 2000. and transmitted securely. For cytokine profiling, the Mann-Whitney U test was applied to ascertain significant differences in immune mediator levels between patients experiencing different fever patterns. 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. Demographic and comorbidity data, symptoms and signs, vital signs, and laboratory and radiology results were obtained from electronic medical records. sharing sensitive information, make sure youre on a federal To investigate whether the fever patterns experienced by the patients are due to differences in immune responses, concentrations of 45 immune mediators were profiled. 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. A prolonged fever of unknown origin (FUO) is simply one that lasts longer than usual, for example, more than the seven to 10 days that you would expect with a simple viral infection. However, there were no significant differences in the admission laboratory values between the control and saddleback fever groups. government site. Cases with prolonged fever were also more likely to require ICU admission compared with controls (11.1% vs 0.9%; P=.05). The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Adverse outcomes were hypoxia, intensive care unit (ICU) admission, mechanical ventilation, and mortality. 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. Pneumonia was present in 26.8% (38/142) of the cohort, of which 21.1% (8/38) required supplemental oxygen; 2.1% (3/142) of patients required ICU admission, 1 of whom required mechanical ventilation. World Health Organisation Special Programme for Research and Training in Tropical Diseases. Home or community isolation facilities and the other iterations for positive cases are commonly used globally to isolate positive patients [34, 35]. Duration of fever was calculated from the date of first symptom onset to the date of defervescence (defined as temperature <37.5C for at least 24 hours) during the hospital admission. Statistical analyses were performed with the Mann-Whitney. Fever was defined as a temperature of 38.0C or higher. Empiric trials of antibiotics or steroids rarely establish a diagnosis and are discouraged in the management of patients with FUO, unless there are clinical indications.5,17,19,21,22 Consultation with a subspecialist (e.g., infectious disease specialist, rheumatologist, hematologist/oncologist) is appropriate at any point in the evaluation. Like RA, rheumatic fever affects the joints. 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). Concentrations of 45 immune mediators in plasma were quantified using a 45-plex microbead-based immunoassay. National Library of Medicine Abdominal and pelvic ultrasonography are often recommended in the initial workup because of availability, low cost, and lack of radiation exposure.15 After the initial evaluation is complete and if there is no diagnosis, the patient is considered to have FUO, and a secondary evaluation should be considered. Empiric antibiotics or steroids are generally discouraged in patients with fever of unknown origin.

Although DHF and SD were more likely to occur in patients in those with saddleback fever, DSS was not. 2021 Mar 8;9(1):E181-E188. It starts suddenly and lasts 3 to 5 days. A fever is a body temperature of 100.4 F or greater. However, it is interesting that there are higher pro-inflammatory IL-1 levels in patients with saddleback fever. The elevation of circulating IL-1RA may reflect overactive IL-1 activation, which has been reported to associated with severe outcomes in COVID-19 [24]. government site. 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 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. Plasma immune mediator levels in COVID-19 patients experiencing different fever patterns. and transmitted securely. Previous testing (ESR, complete blood count, electrolyte panel, chest radiography, urinalysis, blood culture) may be repeated periodically to evaluate for trends as the illness evolves. 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. 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). Eleven patients with prolonged fever, 8 patients with saddleback fever and 56 patients with fever lasting 7 days (controls) were evaluated at the first time point of blood sample collection upon hospitalization (median of 6 days postillness onset) (Figure 1A). [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. P.Y.C. Unmasking latent extrapulmonary tuberculosis with newly diagnosed HIV-1 infection in a COVID-19 patient with prolonged fever. Thank you for submitting a comment on this article. 2022 Oct 31;12:1009894. doi: 10.3389/fcimb.2022.1009894. 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). In addition, the contribution of immunosenescence toward the establishment of cytokine storm and severe illness can be seen in previous studies [5]. FOIA 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. We also excluded 4 patients whose fever pattern did not fulfill the case definition for prolonged or saddleback fever. Europe PMC is an archive of life sciences journal literature. The clinical features of classic KD are shown in Table 1. Lohr JA, Hendley JO.

Prolonged fever was also associated with lower platelet count and higher CRP compared with controls. An official website of the United States government. CONCLUSIONS: Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19. JAMA Intern Med. Outcomes of COVID-19 Among High-Risk Individuals: A Study Comparing Febrile and Afebrile Presentation. Am J Dis Child 1972; 124:544. Open Forum Infect Dis. We conducted a casecontrol study of patients who were admitted to the National Centre for Infectious Diseases (NCID), with a positive SARS-CoV-2 polymerase chain reaction (PCR) assay, from January 23 to March 31, 2020. 2015 Sep 30;15:399. doi: 10.1186/s12879-015-1141-3. 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. This corresponded with a rise in CRP and LDH seen in cases with prolonged fever, which are known to be associated with adverse prognostic factors in COVID-19 [15, 16]. Fever was defined as a temperature of 38.0C. 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 and SD but not DSS. A lower IP-10 level is consistent with the finding that saddleback fever cases tend to have better clinical outcomes than prolonged fever cases. Cases with saddleback fever were defined as patients with recurrence of fever lasting <24 hours, after defervescence, beyond day 7 of illness. This study aims to examine the prevalence of prolonged and saddleback fever in dengue as well as their associations with dengue severity. Normal body temperature can vary depending on the individual, the time of day, and even the weather. Prolonged fever (fever > 7 days duration) was present in 572 (20.1%) of patients. Available at: Ministry of Health (MOH) Singapore. eCollection 2016. Disclaimer. Print 2021 Jan-Mar. 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. We conducted a hospital-based casecontrol 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). 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.

A more recent qualitative definition requires only a reasonable diagnostic evaluation. 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. eCollection 2022. FOUR TYPES OF FEVERS - Read online for free. Cases with prolonged fever were defined as patients with fever lasting >7 days. The .gov means its official. 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. Saddleback fever was significantly associated with hypoxia (14.3% vs 0.9%; P=.03) but not ICU admission (0.9% vs 0.0 %; P=1.00) compared with those in the control group. While prolonged fever was associated with a higher rate of ICU admission vs controls (11.1 percent vs 0.9 percent; p=0.05), saddleback fever was not, despite both being associated with hypoxia. but the rest of the symptoms did not have a difference between the 2 serotypes. 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. -, Bhatt S, Gething PW, Brady OJ, Messina JP, Farlow AW, Moyes CL, 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. Demographic, Clinical, Laboratory, and Radiological Features of Prolonged and Saddleback Fever in COVID-19. Clin Pediatr (Phila) 1977; 16:768. 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. Refining the global spatial limits of dengue virus transmission by evidence-based consensus. 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. The Significance of Prolonged and Saddleback Fever in Hospitalised Adult Dengue. 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).

In patients with saddleback fever, higher levels of IL-1, IL-21, IL-22, and SDF-1 were observed compared with control patients. Saddleback fever was present in 165 (5.8%). The site is secure. ELIZABETH C. HERSCH, COL, MC, USA, AND C. ROBERT, OH, LTC, MC, USA. Other illnesses and inflammation. Cytokines were determined with multiplex microbead-based immunoassay for a subgroup of patients. Nature. 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. Repeat laboratory investigations and CXR were done for those with prolonged or saddleback fever and collected. 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]. Viruses, bacteria, fungi, and parasites can cause infections. -.

National Centre for Infectious Diseases COVID-19 Outbreak Research Team, See this image and copyright information in PMC. 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). Clinicians should perform a comprehensive history and examination to look for potentially diagnostic clues to guide the initial evaluation. 8600 Rockville Pike Although there were no significant differences in white blood cell counts or absolute values of lymphocytes and CRP, we found significant differences in plasma IL-6 and IP-10 levels between the prolonged fever and control patients.

More studies are required to validate the findings of this report. People who wish to treat a fever can try over-the-counter anti-fever medications, such as acetaminophen, aspirin, or ibuprofen. Fever was defined as a temperature of 38.0C. "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. 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]. If there are no potentially diagnostic clues, the patient should undergo a minimum diagnostic workup, including a complete blood count, chest radiography, urinalysis and culture, electrolyte panel, liver enzymes, erythrocyte sedimentation rate, and C-reactive protein level testing. , IL-22, and even the weather in the neck of dengue transmission.
