Clinical characteristics and analysis of risk factors for disease progression of patients with SARS-CoV-2 Omicron variant infection: A retrospective study of 25207 cases in a Fangcang hospital. Financial support. Prolonged fever of unknown origin: a record of experiences with 54 childhood patients. aInvestigations were repeated at the point at which they satisfied criteria for prolonged or saddleback fever. The results of these microbiological investigations were also collected and analyzed. PLoS One. Woon YL, Hor CP, Hussin N, Zakaria A, Goh PP, Cheah WK. Nature. . Plasma fractions, MeSH 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. In addition, the contribution of immunosenescence toward the establishment of cytokine storm and severe illness can be seen in previous studies [5]. 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. Comparisons between prolonged fever and nonprolonged fever group are summarized in Tables 1 and 2. Prolonged fever was defined as fever lasting more than 7 days. 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. Before 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. A more recent qualitative definition requires only a reasonable diagnostic evaluation. Rheumatic fever mostly affects children aged 5-15 years, but it is rare in adults and children aged under 3 years.

Interestingly, there are also higher plasma levels of IL-1RA in patients with prolonged fever compared with control patients. . Your comment will be reviewed and published at the journal's discretion. Influenza (flu) and the common cold are both contagious respiratory illnesses, but they are caused by different viruses. Other illnesses and inflammation. Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19. Clin Pediatr (Phila) 1977; 16:768. RSV is a contagious illness that infects the respiratory tract and can lead to more severe infections like pneumonia or bronchiolitis. Home or community isolation facilities and the other iterations for positive cases are commonly used globally to isolate positive patients [34, 35]. Available at: Wang D, Hu B, Hu C, et al. 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. Higher respiratory rate, lower SpO2, and lower systolic BP were also associated with saddleback fever compared with the control group. A P value of<.05 indicated statistical significance. Additional references were identified from the articles reviewed. There were no deaths in our study. CONCLUSIONS: Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19. Similar fever patterns are observed in COVID-19 with unclear significance. 2013 Oct 20;20(1):75. doi: 10.1186/1423-0127-20-75. -, Bhatt S, Gething PW, Brady OJ, Messina JP, Farlow AW, Moyes CL, et al. Prolonged fever (fever > 7 days duration) was present in 572 (20.1%) of patients. PMC Fever of unknown origin is more often an atypical presentation of a common disease rather than an unusual disease. Ng DH, Wong JG, Thein TL, Leo YS, Lye DC. Statistical analyses were performed using Stata, version 14 (StataCorp, College Station, TX, USA). Those with prolonged fever had a median duration of fever for 10 days (IQR 9-11 days) for prolonged fever cases, while fever recurred at a median of 10 days (IQR 8-12 days) for those with saddleback fever. However, ESR does not help discriminate between active autoimmune disease and infection, and malignancies and noninfectious inflammatory diseases can cause an elevated ESR and CRP level. ; Singapore 2019 Novel Coronavirus Outbreak Research Team. However, it is interesting that there are higher pro-inflammatory IL-1 levels in patients with saddleback fever. Cytokines were determined with multiplex View PDF Save to Library Fever is a nonspecific symptom that may be caused by infectious and noninfectious conditions, including malignancies, systemic rheumatic diseases, and drug reactions. The search included reviews, case series, meta-analyses, and randomized controlled trials. Plasma immune mediator levels in COVID-19 patients experiencing different fever patterns. 2014; 8: e2777 10.1371/journal.pntd.0002777 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. 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). Shivering, shaking, and chills Aching muscles and joints or other body aches Headache Intermittent sweats or excessive sweating Rapid heart rate and/or palpitations Skin flushing or hot skin Feeling faint, dizzy, or lightheaded Eye pain or sore eyes Weakness Loss of appetite Fussiness (in children and toddlers) But normal body temperature can range between 97 F (36.1 C) and 99 F (37.2 C) or more. Physicians may consider stopping antimicrobials if all investigations are unyielding and patients remain hemodynamically stable. 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. Bethesda, MD 20894, Web Policies P.Y.C. In conclusion, we reported on the prevalence, risk factors, cytokine profiles, and outcomes of patients with COVID-19 who had saddleback or prolonged fever. J Biomed Sci. CMAJ Open. 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. Prolonged fever was also associated with lower platelet count and higher CRP compared with controls. Confirmed imported case of novel coronavirus infection in Singapore; multi-ministry taskforce ramps up precautionary measures.2020. This site needs JavaScript to work properly. 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). Corticosteroids for treating mild COVID-19: opening the floodgates of therapeutic misadventure. In patients with saddleback fever, higher levels of IL-1, IL-21, IL-22, and SDF-1 were observed compared with control patients. The global distribution and burden of dengue. National Library of Medicine eCollection 2017 Summer. Keywords: Published by Oxford University Press on behalf of Infectious Diseases Society of America. In contrast, cases with saddleback fever showed no significant change upon repeating their laboratory tests. 2013 Jul;23(7):463-7. Viruses, bacteria, fungi, and parasites can cause infections. JAMA 2020; 323(11):10619. Available at: Ministry of Health (MOH) Singapore. Fever often occurs in response to infection, inflammation and trauma. Concentrations of 45 immune mediators in plasma were quantified using a 45-plex microbead-based immunoassay. doi: 10.1371/journal.pntd.0002412. Patients with prolonged fever may have had higher levels of IL-1 earlier on before sample collection. We also excluded 4 patients whose fever pattern did not fulfill the case definition for prolonged or saddleback fever. Careers. A fever is a rise in body temperature. IL-1RA is naturally secreted by human hosts to limit the activity of IL-1 during hyperinflammation [22]. Infect Drug Resist. 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). If noninvasive diagnostic tests are unrevealing, then the invasive test of choice is a tissue biopsy because of the relatively high diagnostic yield. The site is secure. Recommendations of the Scientific Working Group on Dengue. 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. Conclusions: Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19. 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). Concentrations of 45 immune mediators in plasma were quantified using a 45-plex microbead-based immunoassay. COVID-19 and sinus infections share several symptoms like nasal congestion, fever, and coughing. 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. 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).

For cases with saddleback fever, fever recurred at a median (IQR) of 10 (812) days after symptom onset. Additional microbiological investigations, such as blood and urine cultures, influenza and respiratory viral multiplex PCR, dengue NS1 and serology, were ordered at the discretion of the primary treating clinician. Patients who tested positive were not discharged until they had 2 negative PCR tests 24 hours apart [13]. Prolonged fever is associated with adverse outcomes in dengue viral infection. Approval for data collection by retrospective chart review with a waiver of written informed consent from study participants was granted by the Singapore Ministry of Health under the Infectious Diseases Act as part of the outbreak investigation [14]. Pung R, Chiew CJ, Young BE, et al. 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. Repeat laboratory investigations and CXR were done for those with prolonged or saddleback fever and collected. Qiu H, Wu J, Hong L, Luo Y, Song Q, Chen D. Arend WP, Malyak M, Guthridge CJ, Gabay C. Essayan DM, Fox CC, Levi-Schaffer F, Alam R, Rosenwasser LJ. PLoS Negl Trop Dis. FOIA 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). The 4 cases who were excluded from the primary analysis demonstrated a saddleback pattern of fever that lasted >24 hours. 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). Geneva: World Health Organization, Special Programme for Research and Training in Tropical Diseases, Geneva: 2000. 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. 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. 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. 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. -. Both prolonged (27.8% vs 0.9%, p <0.01) and saddleback fever (14.3% vs 0.9%, p= 0.03) were associated with hypoxia compared to controls. 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. Prolonged fever is associated with adverse outcomes in dengue viral infection. The .gov means its official. 2022 Jul 26;2022(7):omac079. Conti P, Panara MR, Barbacane RC, et al. 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]. The findings of the study are useful for informing the optimal placement of patients with COVID-19, the researchers pointed out. But there are some important differences. 40-year-old woman fever rash arthralgia Dx? Our observational study observed the 24-h continuous tympanic temperature pattern of 15 patients with dengue fever and . Biphasic Zika Illness With Rash and Joint Pain. 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. 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. Importantly, upregulation of the IL-1 pathway on monocytes can increase prostaglandin E2 expression and drive fever [32]. A more recent article on fever of unknown origin in adults is available. Available at: Ministry of Health (MOH) Singapore. eCollection 2022. Upon admission, all patients underwent a chest x-ray (CXR), admission full blood count (FBC), renal and liver panel, C-reactive protein (CRP), lactate dehydrogenase (LDH), and nasopharyngeal swab for SARS-CoV-2 PCR. Retrospective characterisation and outcome of surgical treatment for cervical lymph node abscessation in 15 dogs. 7 days, a Singapore study reveals. Disclaimer. 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.
