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. 2022 May 20;15:2575-2587. doi: 10.2147/IDR.S355064. Heart Lung. Copyright 2014 by the American Academy of Family Physicians. 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. 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. Woon YL, Hor CP, Hussin N, Zakaria A, Goh PP, Cheah WK. The author(s) received no specific funding for this work. and transmitted securely. Cases with prolonged fever were also more likely to require ICU admission compared with controls (11.1% vs 0.9%; P = .05). Unauthorized use of these marks is strictly prohibited. Mallhi TH, Khan AH, Adnan AS, Sarriff A, Khan YH, Jummaat F. BMC Infect Dis. Statistical analyses were performed using GraphPad Prism, version 8. Physicians may consider stopping antimicrobials if all investigations are unyielding and patients remain hemodynamically stable. For cytokine profiling, the Mann-Whitney U test was applied to ascertain significant differences in immune mediator levels between patients experiencing different fever patterns. Search life-sciences literature (41,164,937 (41,164,937 Communicable Diseases Surveillance in Singapore 2005. 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. More studies are required to validate the findings of this report. J Microbiol Immunol Infect. Recommendations of the Scientific Working Group on Dengue. A fever may be caused by a virus, bacteria, fungus, blood clot, tumor, drug, or the environment. 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. PLoS Negl Trop Dis 2012; 6(8): e1760 10.1371/journal.pntd.0001760 However, there were no significant differences in the admission laboratory values between the control and saddleback fever groups. 2020 Oct 28;21(1):897. doi: 10.1186/s13063-020-04819-9. A fever is a rise in body temperature. Safety and Efficacy of Imatinib for Hospitalized Adults with COVID-19: A structured summary of a study protocol for a randomised controlled trial. 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). 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. 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. Clipboard, Search History, and several other advanced features are temporarily unavailable. Seven more confirmed cases of novel coronavirus infection in Singapore. Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19. 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. Further testing should include blood cultures, lactate dehydrogenase, creatine kinase, rheumatoid factor, and antinuclear antibodies. Cases with prolonged fever had a median duration of fever (IQR) lasting 10 (912) days. It starts suddenly and lasts 3 to 5 days. Europe PMC is an archive of life sciences journal literature. The higher levels of IL-1 could initiate the first occurrence of fever, while the pro-inflammatory cytokines IL-21 and IL-22 mediate the activation of T cells and M1 macrophages [25, 26], which drive the recurrence of fever in saddleback fever cases. A larger cohort might help to improve our understanding of these patients. 2022 Jul 26;2022(7):omac079. doi: 10.1371/journal.pone.0167025. Corticosteroids for treating mild COVID-19: opening the floodgates of therapeutic misadventure. Hirata K, Watanabe K, Sasaki T, Yoshimasu T, Shimomura A, Ando N, Yanagawa Y, Mizushima D, Teruya K, Kikuchi Y, Oka S, Tsukada K. Oxf Med Case Reports. Figure 1 outlines a diagnostic approach to patients with prolonged febrile illness and FUO.1,2,47,1520,23,27, Hospitalization may be considered at any time during the evaluation, especially if the patient exhibits signs of a critical illness. Front Cell Infect Microbiol. The 18F fluorodeoxyglucose has better uptake and is cleared more rapidly than older modalities (e.g., gallium Ga 67 citrate), but it is costly and not widely available.14, Liver, lymph node, or temporal artery biopsy may help establish a definitive diagnosis.3,19 A prospective study of 192 patients found that biopsies produced up to a 35% diagnostic yield (about 10% to 35%), especially if performed later in the evaluation when infection is less likely, and malignancies and noninfectious inflammatory diseases are more common.2 Liver biopsy, with a diagnostic yield between 14% and 17%,5,19 can reveal granulomatous hepatitis and determine its cause, which could be infectious, inflammatory, or neoplastic processes.22,27 Lymph node biopsy is most useful in diagnosing lymphoma, infectious diseases, and granulomatous diseases.19,27 In patients 55 years or older, temporal arteritis causes more than 15% of cases of FUO, so biopsy should be considered.5,15,18, Bone marrow biopsy is diagnostically useful, particularly with neoplasm and infectious disease, especially tuberculosis.19,27 One study of 280 hospitalized febrile patients found that bone marrow biopsy was helpful in reaching a diagnosis in nearly 25% of the 130 patients who underwent biopsy.41 Conversely, bone marrow aspiration and culture have a diagnostic yield of only 0% to 2%.3,5,15,22,41. Dengue fever is an acute febrile illness with a duration of 2-12 days. 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]. Concentrations of 45 immune mediators in plasma were quantified using a 45-plex microbead-based immunoassay. World Health Organisation Special Programme for Research and Training in Tropical Diseases. Before Out-of-hospital cardiac arrest and in-hospital mortality among COVID-19 patients: A population-based retrospective cohort 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). Cytokine level for healthy controls (n=23) is indicated by the black dotted line. 2021 Jan-Feb;50(1):28-32. doi: 10.1016/j.hrtlng.2020.10.013.

Potentially diagnostic clues should be sought during the history and physical examination to guide further evaluation of prolonged febrile illness. In particular, fever was reported in about 72%98.6% of patients, usually lasting <7 days [4, 710]. Prolonged fever of unknown origin in children. 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. doi: 10.1093/ofid/ofx133. When there are no clear localizing signs or symptoms, clinicians should expand on the patient's symptoms and historical information, looking for potentially diagnostic clues to guide the evaluation (Table 4).1720,25,27 This is a continuous, iterative process.1921 Potentially diagnostic clues lead to a diagnosis in 62% of patients, although clues can be misleading because they are found in 97% of patients.1517, If no potentially diagnostic clues are found, a minimum diagnostic workup should be performed. 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. 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. FOUR TYPES OF FEVERS - Read online for free. A lower IP-10 level is consistent with the finding that saddleback fever cases tend to have better clinical outcomes than prolonged fever cases. Clin Pediatr (Phila) 1977; 16:768. The results of these microbiological investigations were also collected and analyzed. In addition to their pro-inflammatory properties, both IL-6 and IP-10 have been reported to be associated with disease severity and ICU admission in COVID-19 [18, 19] .

Dengue fever is gaining importance in Singapore with an increase in the number of cases and mortality in recent years. History and physical examination alone are often sufficient to diagnose uncomplicated infectious causes of fever . 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. 2022 Oct 31;12:1009894. doi: 10.3389/fcimb.2022.1009894. 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). Statistical analyses were performed with the Mann-Whitney. These patients required prolonged periods of observation and symptomatic treatment. Author disclosure: No relevant financial affiliations. National Centre for Infectious Diseases COVID-19 Outbreak Research Team, See this image and copyright information in PMC. PMC On repeat testing, prolonged fever was associated with a drop in hemoglobin and a rise in CRP and LDH (Table 2). Antibiotics usually aren't prescribed just because a child has a fever that is lasting a long time. Fever is a nonspecific symptom that may be caused by infectious and noninfectious conditions, including malignancies, systemic rheumatic diseases, and drug reactions. The global distribution and burden of dengue. 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. Accessibility Blue and red represent low and high concentrations, respectively. aInvestigations were repeated at the point at which they satisfied criteria for prolonged or saddleback fever. doi: 10.1371/journal.pntd.0002412. 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. 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. An official website of the United States government. 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. 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. 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. Importantly, upregulation of the IL-1 pathway on monocytes can increase prostaglandin E2 expression and drive fever [32]. 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.

National Library of Medicine The Wilcoxon signed-rank test was used to evaluate for differences in paired samples. 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. Prolonged fever (fever > 7 days duration) was present in 572 (20.1%) of patients. Plasma immune mediator levels in COVID-19 patients experiencing different fever patterns. . Your comment will be reviewed and published at the journal's discretion. Plasma fractions were isolated from blood samples of COVID-19 patients collected during the acute phase (median post-illness onset, 6 days). Prolonged fever was defined as fever lasting more than 7 days. 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. 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).

Some children also may have a sore throat, runny nose or cough along with or before the fever. 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].

Data were collected for the remaining 110 patients from this cohort as controls; 57.0% (81/142) of all study subjects were male, and the median age (interquartile range [IQR]) was 42 (3154) years. Results: Infect Drug Resist. 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. 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. 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. Although there are more than 200 diseases in the differential diagnosis, most cases in adults are limited to several dozen possible causes. Viruses, bacteria, fungi, and parasites can cause infections. A more recent article on fever of unknown origin in adults is available. Lohr JA, Hendley JO.

Nature. 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. 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. 2021 Mar 8;9(1):E181-E188. Plasma immune mediator levels in COVID-19 patients experiencing different fever patterns. COVID-19 and sinus infections share several symptoms like nasal congestion, fever, and coughing.
