Safety and Efficacy of Imatinib for Hospitalized Adults with COVID-19: A structured summary of a study protocol for a randomised controlled trial. Prolonged fever was also associated with lower platelet count and higher CRP compared with controls. Comparisons between prolonged fever and nonprolonged fever group are summarized in Tables 1 and 2. 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. Higher heart rate and respiratory rate and lower oxygen saturation (spO2), systolic and diastolic blood pressure (BP) were associated with prolonged fever compared with controls (Table 1). 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 there are some important differences. Fever is a nonspecific symptom that may be caused by infectious and noninfectious conditions, including malignancies, systemic rheumatic diseases, and drug reactions. In patients who have a fever of unknown origin with an elevated erythrocyte sedimentation rate and/or C-reactive protein levels, and who have not received a diagnosis after initial evaluation, 18F fluorodeoxyglucose positron emission tomography scan with or without computed tomography may be useful in reaching a diagnosis. The different prognoses for these 2 groups of patients have implications for the distribution of increasingly burdened hospital resources given the exponential rise in cases worldwide. PLoS One. Interestingly, there are also higher plasma levels of IL-1RA in patients with prolonged fever compared with control patients. 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). Risk Factors Associated With Mortality Among Patients With COVID-19 in Intensive Care Units in Lombardy, Italy. FOIA Fever of unknown origin (FUO) in adults is one of the most vexing clinical conditions for clinicians and patients. 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. 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. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Normal body temperature can vary depending on the individual, the time of day, and even the weather. -. COVID-19 and sinus infections share several symptoms like nasal congestion, fever, and coughing. 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. JAMA 2020; 323(11):10619. Prolonged fever in children: review of 100 cases. Although DHF and SD were more likely to occur in patients in those with saddleback fever, DSS was not. CONCLUSIONS: Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19. 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. Cases with prolonged fever were defined as patients with fever lasting >7 days. Federal government websites often end in .gov or .mil. 2021 Nov 5;114(8):541-542. doi: 10.1093/qjmed/hcab138. 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]. Open Forum Infect Dis. But normal body temperature can range between 97 F (36.1 C) and 99 F (37.2 C) or more. but the rest of the symptoms did not have a difference between the 2 serotypes. The 2011 dengue haemorrhagic fever outbreak in Lahore - an account of clinical parameters and pattern of haemorrhagic complications. Hypoxia was defined as requirement for supplemental oxygen. While both prolonged and saddleback fever showed an association with hypoxia, only prolonged fever was associated with ICU admission. Notably, patients with prolonged fever had higher IP-10 and lower IL-1 levels as compared with patients with saddleback fever (Figure 1B). 2013; 496: 504507. Additional references were identified from the articles reviewed. 8600 Rockville Pike Conclusions: Mallhi TH, Khan AH, Adnan AS, Sarriff A, Khan YH, Jummaat F. BMC Infect Dis. For cytokine profiling, the Mann-Whitney U test was applied to ascertain significant differences in immune mediator levels between patients experiencing different fever patterns. 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. 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. PMC 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). [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. 2020 Oct 1;180(10):1345-1355. doi: 10.1001/jamainternmed.2020.3539. The .gov means its official. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). More studies are required to validate the findings of this report. 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.

J Coll Physicians Surg Pak. Statistical analyses were performed using GraphPad Prism, version 8. 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. Erythrocyte sedimentation rate and C-reactive protein levels should be measured in the initial workup of a patient who has prolonged febrile illness without a clear source. This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. government site. Statistical data analysis on the types of fevers 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 ). 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). Saddleback fever was present in 165 (5.8%). QJM. Plasma fractions were isolated from blood samples of COVID-19 patients collected during the acute phase (median post-illness onset, 6 days). Careers. Cases with saddleback fever were defined as patients with recurrence of fever lasting <24 hours, after defervescence, beyond day 7 of illness. 2014; 8: e2777 10.1371/journal.pntd.0002777 Singapore reported its first imported case of COVID-19 in a traveler from Wuhan on January 23, 2020, followed by its first locally transmitted case on February 7, 2020 [2, 3]. Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19. Out-of-hospital cardiac arrest and in-hospital mortality among COVID-19 patients: A population-based retrospective cohort study. In general, fever is defined as a temperature > 38C (100.4F). Nature. On repeat testing, prolonged fever was associated with a drop in hemoglobin and a rise in CRP and LDH (Table 2). Conflicts that the editors consider relevant to the content of the manuscript have been disclosed. Fever duration was longer in patients 6 to 12 months old and 12 to 18 . 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. Lohr JA, Hendley JO. J Biomed Sci. 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]. The https:// ensures that you are connecting to the 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. A Two-Year Review on Epidemiology and Clinical Characteristics of Dengue Deaths in Malaysia, 2013-2014. Results: 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. 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. Coronavirus disease 2019 (COVID-19) situation report101. Before Copyright 2023 MIMS Pte Ltd. All rights reserved. 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. Dengue fever is gaining importance in Singapore with an increase in the number of cases and mortality in recent years. The results of this study can be used to optimize placement of patients with COVID-19. Outcomes of interest were hypoxia, admission to the intensive care unit (ICU), need for mechanical ventilation, and mortality. HHS Vulnerability Disclosure, Help The median age was 34 years of age (5 th - 95 th percentile: 17-59) and males comprised 1971 (69.3%) of study sub- A P value of<.05 indicated statistical significance. Never give a child aspirin, as this increases the risk of . Similar fever patterns are observed in COVID-19 with unclear significance. . Background: All authors: no reported conflicts of interest. The 4 cases who were excluded from the primary analysis demonstrated a saddleback pattern of fever that lasted >24 hours. Patients were categorized as having prolonged fever (lasting >7 days), saddleback fever (defined as recurrent fever which lasts for <24 hours, after defervescence beyond day 7 of illness), or controls if their fever was 7 days. Clin Pediatr (Phila) 1977; 16:768. Some children also may have a sore throat, runny nose or cough along with or before the fever. Since its first report in Wuhan, China, in December 2019, COVID-19 has rapidly spread, becoming a pandemic with more than 3 million confirmed cases [1]. In addition, IP-10 has also been reported to be associated with increased viral load, lung injury, ICU admission, and mortality [21]. . This circadian rhythm may differ among individuals but should be consistent in each person . Unable to load your collection due to an error, Unable to load your delegates due to an error, Collaborators, Affiliations, Plasma immune mediator levels in COVID-19 patients experiencing different fever patterns. 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. ; Singapore 2019 Novel Coronavirus Outbreak Research Team. 2017 Jun 22;4(3):ofx133. Although there are more than 200 diseases in the differential diagnosis, most cases in adults are limited to several dozen possible causes. We also excluded 4 patients whose fever pattern did not fulfill the case definition for prolonged or saddleback fever. Prolonged fever is associated with adverse outcomes in dengue viral infection. 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. Statistical analyses were performed with the Mann-Whitney. 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 . Epub 2020 Oct 21. RSV is a contagious illness that infects the respiratory tract and can lead to more severe infections like pneumonia or bronchiolitis. eCollection 2022. -. Corticosteroids for treating mild COVID-19: opening the floodgates of therapeutic misadventure. 2013 Jul;23(7):463-7. All authors have submitted the ICMJE Form for Disclosure of Potential Conflicts of Interest. Teleconferencing is often used to monitor these cases for potential deterioration. Patients with saddleback fever appeared to have good outcomes regardless of the fever. Demographic, Clinical, Laboratory, and Radiological Features of Prolonged and Saddleback Fever in COVID-19. The most common subgroups in the differential are infection, malignancy, noninfectious inflammatory diseases, and miscellaneous. Pediatrics 1975; 55:468. One limitation of the study is the small sample size of our cohort. Repeat laboratory investigations and CXR were done for those with prolonged or saddleback fever and collected. Effects of sericin and egg white on the inflammation of damaged skin in mice. 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. Cases without prolonged or saddleback fever were included as controls. 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. Depending on clinical clues, this may include liver, lymph node, temporal artery, or bone marrow biopsy. A fever may be caused by a virus, bacteria, fungus, blood clot, tumor, drug, or the environment. Retrospective characterisation and outcome of surgical treatment for cervical lymph node abscessation in 15 dogs. Geneva: World Health Organization, Special Programme for Research and Training in Tropical Diseases, Geneva: 2000. A. Ministry of Health Singapore. Available at: Wang D, Hu B, Hu C, et al. Despite the progression on CXR in over one-third of cases with saddleback fever, these cases tend to do well. 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). Cases with prolonged fever were also more likely to require ICU admission compared with controls (11.1% vs 0.9%; P=.05). In hypoxic conditions, it can trigger the expression of chemokines that attract neutrophils and monocytes to the ischemic tissue [31]. 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. Clipboard, Search History, and several other advanced features are temporarily unavailable. 2021 Mar 8;9(1):E181-E188.

Seven more confirmed cases of novel coronavirus infection in Singapore. 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. Abbreviations: ALT, alanine aminotransferase; AST, aspartate aminotransferase; BP, blood pressure; CRP, C-reactive protein; LDH, lactate dehydrogenase. 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. This site needs JavaScript to work properly. 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. Bethesda, MD 20894, Web Policies Huy NT, Van Giang T, Thuy DH, Kikuchi M, Hien TT, Zamora J, Hirayama K. PLoS Negl Trop Dis. 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. Higher respiratory rate, lower SpO2, and lower systolic BP were also associated with saddleback fever compared with the control group. 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. 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. Mahmood A.
