difference between prolonged fever and saddleback fever
World Health Organisation Special Programme for Research and Training in Tropical Diseases. 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. 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). Oxford University Press is a department of the University of Oxford. Conti P, Panara MR, Barbacane RC, et al. Roseola symptoms might include: Fever. 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. Please enable it to take advantage of the complete set of features! Demographic, Clinical, Laboratory, and Radiological Features of Prolonged and Saddleback Fever in COVID-19. -. 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. 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. A lower IP-10 level is consistent with the finding that saddleback fever cases tend to have better clinical outcomes than prolonged fever cases. Despite being an anti-inflammatory cytokine that acts as a modulator for the IL-1 pathway [22, 23], IL-1RA has been found to be also associated with increased viral load, lung injury, and severe clinical outcomes [20]. Note that serologic tests are helpful only if there are potentially diagnostic clues and if the patient lives in or has visited an area where the suspected disease is prevalent.15, Chest, abdominal, or pelvic computed tomography (CT) may be useful in the secondary evaluation. 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. Accessibility A. Am J Dis Child 1972; 124:544. 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. 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). Epub 2020 Oct 21. 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. 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]. If there is no clear source of infection, then further testing should follow. Rowe EK, Leo Y-S, Wong JGX, Thein T-L, Gan VC, Lee LK, et al. All efforts have been undertaken to anonymize the data. Seven more confirmed cases of novel coronavirus infection in Singapore.2020. Some children also may have a sore throat, runny nose or cough along with or before the fever. On repeat testing, prolonged fever was associated with a drop in hemoglobin and a rise in CRP and LDH (Table 2). bOnly 1 sample of paired values available. However, it is interesting that there are higher pro-inflammatory IL-1 levels in patients with saddleback fever. J Microbiol Immunol Infect. 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). A larger cohort might help to improve our understanding of these patients. A fever is a rise in your body temperature. A more recent article on fever of unknown origin in adults is available. 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. 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. A standardized template was used for recording daily signs and symptoms, vital signs, and management. Europe PMC is an archive of life sciences journal literature. Statistical data analysis on the types of fevers Although DHF and SD were more likely to occur in patients in those with saddleback fever, DSS was not. Fever was defined as a temperature of 38.0C. Fever duration was longer in patients 6 to 12 months old and 12 to 18 . Other illnesses and inflammation. The search included reviews, case series, meta-analyses, and randomized controlled trials. But there are some important differences. Members of the National Centre for Infectious Diseases COVID-19 Outbreak Research Team. 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]. Higher respiratory rate, lower SpO2, and lower systolic BP were also associated with saddleback fever compared with the control group. Conflicts that the editors consider relevant to the content of the manuscript have been disclosed. 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. eCollection 2022. FOUR TYPES OF FEVERS - Read online for free. Methods: 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. 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. The global distribution and burden of dengue. 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. FOIA COVID-19 generally presents as an acute respiratory illness, with fever, fatigue, and dry cough being commonly reported symptoms [46]. COVID-19 and sinus infections share several symptoms like nasal congestion, fever, and coughing. Patients with saddleback fever appeared to have good outcomes regardless of the fever. A, Heatmap showing the relative concentration of cytokines across patients with different fever patterns. aInvestigations were repeated at the point at which they satisfied criteria for prolonged or saddleback fever. 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. The https:// ensures that you are connecting to the PLoS Negl Trop Dis. Approximately 12% to 35% of patients die from an FUO-related cause (generally infection or malignancy), yet of those whose conditions remain undiagnosed, most recover or have a benign course with a good prognosis.5,22. Blue and red represent low and high concentrations, respectively. An official website of the United States government. 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. 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]. ; Singapore 2019 Novel Coronavirus Outbreak Research Team. Outcomes of patients with COVID-19 in the intensive care unit in Mexico: A multicenter observational study. doi: 10.1371/journal.pntd.0004575. At the time of writing, there were no supporting studies on the association between elevated levels of IL-21, IL-22, and SDF-1 and COVID-19. Interestingly, there are also higher plasma levels of IL-1RA in patients with prolonged fever compared with control patients. Depending on clinical clues, this may include liver, lymph node, temporal artery, or bone marrow biopsy. Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19, said the researchers led by Dr Deborah Ng from National Centre for Infectious Diseases (NCID), Singapore, on behalf of the NCID COVID-19 Outbreak Research Team. eCollection 2013. Ng DH, Wong JG, Thein TL, Leo YS, Lye DC. Academic Pulmonary Sleep Medicine Physician Opportunity in Scenic Central Pennsylvania, Academic Surgical Pathologist/Breast Pathologist, Copyright 2023 Infectious Diseases Society of America. Similar fever patterns are observed in COVID-19 with unclear significance. "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. 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. 2021 Nov 5;114(8):541-542. doi: 10.1093/qjmed/hcab138.

Published by Oxford University Press on behalf of Infectious Diseases Society of America. HHS Vulnerability Disclosure, Help The Wilcoxon signed-rank test was used to evaluate for differences in paired samples. In addition, IP-10 has also been reported to be associated with increased viral load, lung injury, ICU admission, and mortality [21]. In many cases, no specific cause of the fever is found, 2 . 2013 Sep 26;7(9):e2412. 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. Fever was defined as a temperature of 38.0C or higher. official website and that any information you provide is encrypted 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. Woon YL, Hor CP, Hussin N, Zakaria A, Goh PP, Cheah WK. The 2011 dengue haemorrhagic fever outbreak in Lahore - an account of clinical parameters and pattern of haemorrhagic complications. -, Bhatt S, Gething PW, Brady OJ, Messina JP, Farlow AW, Moyes CL, et al. . 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. Patients with saddleback fever appeared to have good outcomes regardless of the fever. The authors have declared that no competing interests exist. 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). Both COVID-19 and the common cold can include a runny nose, sore throat, and fever, says Dr. Fisher, and both can last between a few days or a week. 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 . For most people, a temperature of 98.6 F or 37 C is baseline. Prolonged fever was also associated with lower platelet count and higher CRP compared with controls. Home or community isolation facilities and the other iterations for positive cases are commonly used globally to isolate positive patients [34, 35]. The most common subgroups in the differential are infection, malignancy, noninfectious inflammatory diseases, and miscellaneous. A, Heatmap showing the relative concentration of cytokines across patients with different fever patterns. 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). 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. Clin Pediatr (Phila) 1977; 16:768.

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. Conclusions: Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19. 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.
