A Two-Year Review on Epidemiology and Clinical Characteristics of Dengue Deaths in Malaysia, 2013-2014. 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). The Author(s) 2020. Huy NT, Van Giang T, Thuy DH, Kikuchi M, Hien TT, Zamora J, Hirayama K. PLoS Negl Trop Dis. as they fulfilled overlapping criteria for prolonged and saddleback fever. The analysis, which was. Would you like email updates of new search results? 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) Treatment of fever in adults usually involves ibuprofen, acetaminophen, or aspirin. Cavalli G, De Luca G, Campochiaro C, et al. It starts suddenly and lasts 3 to 5 days. . Ying-Hao P, Yuan-Yuan G, Hai-Dong Z, Qiu-Hua C, Xue-Ran G, Hai-Qi Z, Hua J. Like RA, rheumatic fever affects the joints. At the time of writing, the mortality rate from COVID-19 in Singapore was 0.09% [36]. 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. For cases with saddleback fever, fever recurred at a median (IQR) of 10 (812) days after symptom onset. Recommendations of the Scientific Working Group on Dengue. Fever of unknown origin (FUO) in adults is one of the most vexing clinical conditions for clinicians and patients. Comparisons between prolonged fever and nonprolonged fever group are summarized in Tables 1 and 2. Influenza (flu) and the common cold are both contagious respiratory illnesses, but they are caused by different viruses. A lower IP-10 level is consistent with the finding that saddleback fever cases tend to have better clinical outcomes than prolonged fever cases. Cytokines were determined with multiplex microbead-based immunoassay for a subgroup of patients. 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. Fever often occurs in response to infection, inflammation and trauma. History and physical examination alone are often sufficient to diagnose uncomplicated infectious causes of fever . Pediatrics 1975; 55:468. JAMA 2020; 323(11):10619. Members of the National Centre for Infectious Diseases COVID-19 Outbreak Research Team. In patients with saddleback fever, higher levels of IL-1, IL-21, IL-22, and SDF-1 were observed compared with control patients. Clinical features of patients infected with 2019 novel coronavirus in Wuhan, China. Physicians may consider stopping antimicrobials if all investigations are unyielding and patients remain hemodynamically stable. Young BE, Ong SWX, Kalimuddin S, et al. Retrospective characterisation and outcome of surgical treatment for cervical lymph node abscessation in 15 dogs. 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. Those with prolonged fever had a median duration of fever (interquartile range [IQR]) of 10 (9-11) days for prolonged fever cases, while fever recurred at a median (IQR) of 10 (8-12) days for those with saddleback fever. 8600 Rockville Pike Epub 2020 Oct 21. Prolonged fever beyond 7 days from onset of illness can identify patients who may be at risk of adverse outcomes from COVID-19. 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. 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. In addition, in comparison with other parameters such as respiratory rate, heart rate, or blood pressure, fever is easy to detect and readily identifiable as a risk factor for severe disease. Rheumatic fever mostly affects children aged 5-15 years, but it is rare in adults and children aged under 3 years. 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. 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 ). The levels of other immune mediators measured were not significantly different between groups. Careers. The global distribution and burden of dengue. Cases without prolonged or saddleback fever were included as controls. Some children also may have a sore throat, runny nose or cough along with or before the fever. Prevalence and Predictors of Persistent Symptoms After Clearance of SARS-CoV-2 Infection: A Multicenter Study from Egypt. The 4 cases who were excluded from the primary analysis demonstrated a saddleback pattern of fever that lasted >24 hours. Cytokines were determined with multiplex microbead-based immunoassay for a subgroup of patients. CMAJ Open. The https:// ensures that you are connecting to the While both prolonged and saddleback fever showed an association with hypoxia, only prolonged fever was associated with ICU admission. 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. 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).

There are no published guidelines, nor is there a recommended standard approach to the diagnosis. 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. Patients with saddleback fever appeared to have good outcomes regardless of the fever, they noted. The .gov means its official. P.Y.C. and transmitted securely. 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. Ministry of Health Singapore. Patients with saddleback fever appeared to have good outcomes regardless of the fever. Unable to load your collection due to an error, Unable to load your delegates due to an error, Collaborators, 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. -. Roseola often starts with a high fever often higher than 103 F (39.4 C). COVID-19 and sinus infections share several symptoms like nasal congestion, fever, and coughing. Trials. Demographic and comorbidity data, symptoms and signs, vital signs, and laboratory and radiology results were obtained from electronic medical records. Seven more confirmed cases of novel coronavirus infection in Singapore.2020. 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. PLoS One. Laboratory Results for Prolonged and Saddleback Fever. IL-1 is dual function cytokine that can act as both a transcription factor and a damage-associated molecular pattern (DAMP), which can be released by necrotic cells to promote and exacerbate inflammation via IL-1R1 [30]. This corroborated well with our findings of increased hypoxia in patients with prolonged fever. 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. Affiliations, Plasma immune mediator levels in COVID-19 patients experiencing different fever patterns. 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. Europe PMC is an archive of life sciences journal literature. Copyright 2023 MIMS Pte Ltd. All rights reserved. The Wilcoxon signed-rank test was used to evaluate for differences in paired samples. All authors have submitted the ICMJE Form for Disclosure of Potential Conflicts of Interest. 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. 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. Cases with prolonged fever were also more likely to require ICU admission compared with controls (11.1% vs 0.9%; P = .05). Despite the progression on CXR in over one-third of cases with saddleback fever, these cases tend to do well. Available at: Wang D, Hu B, Hu C, et al. However, it is interesting that there are higher pro-inflammatory IL-1 levels in patients with saddleback fever. 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. Factors associated with dengue shock syndrome: a systematic review and meta-analysis. Disclaimer. Unauthorized use of these marks is strictly prohibited. The findings of the study are useful for informing the optimal placement of patients with COVID-19, the researchers pointed out. 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. Your child may also develop swollen lymph nodes in the neck. 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]. In many cases, no specific cause of the fever is found, 2 . Out-of-hospital cardiac arrest and in-hospital mortality among COVID-19 patients: A population-based retrospective cohort study. Accessibility A dysregulated immune response in COVID-19 has been postulated to lead a deleterious cytokine storm [12]. The average body temperature is 98.6 F (37 C). 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. 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. Fever was defined as a temperature of 38.0C. None had symptoms of urinary tract infection, thrombophlebitis, or Clostridioidesdifficile diarrhea. 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. In general, fever is defined as a temperature > 38C (100.4F). 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. People who wish to treat a fever can try over-the-counter anti-fever medications, such as acetaminophen, aspirin, or ibuprofen. doi: 10.1093/ofid/ofx133. 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. 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. Moreover, cases with prolonged fever also showed significantly higher plasma levels of inflammatory biomarkers such as interleukin (IL)-6 (p<0.01), IL-1RA (p<0.05), and induced protein-10 (IP-10; p<0.001) compared with controls during the early acute disease phase. Two remained in the general ward throughout their stay without any complications, while 2 were admitted to the ICU, 1 of whom died from acute respiratory distress syndrome. 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]. In particular, fever was reported in about 72%98.6% of patients, usually lasting <7 days [4, 710]. Bethesda, MD 20894, Web Policies The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). The results of this study can be used to optimize placement of patients with COVID-19. Please enable it to take advantage of the complete set of features! 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. [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. FOIA Concentrations of 45 immune mediators in plasma were quantified using a 45-plex microbead-based immunoassay. Plasma fractions were isolated from blood samples of COVID-19 patients collected during the acute phase (median post-illness onset, 6 days). 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. 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. Plasma fractions were isolated from blood samples of COVID-19 patients collected during the acute phase (median post-illness onset, 6 days). 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. All efforts have been undertaken to anonymize the data. 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. Dengue hemorrhagic fever (DHF), dengue shock syndrome (DSS) and severe dengue (SD) were significantly more likely to occur in patients with prolonged fever. Unmasking latent extrapulmonary tuberculosis with newly diagnosed HIV-1 infection in a COVID-19 patient with prolonged fever. Cases with prolonged fever were also more likely to require ICU admission compared with controls (11.1% vs 0.9%; P=.05). 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. Interim guidance for implementing home care of people not requiring hospitalization for coronavirus disease 2019 (COVID-19). Clinico-laboratory spectrum of dengue viral infection and risk factors associated with dengue hemorrhagic fever: a retrospective study.

Copyright 2014 by the American Academy of Family Physicians. The definition of what constitutes FUO remains controversial.1,2 FUO was first described in a 1961 case series as prolonged febrile illness (temperature of 101F [38.3C] or higher) for three weeks or longer that did not have an established etiology despite a one-week inpatient evaluation.3,4 The arbitrarily defined three weeks allowed most acute, self-limited illnesses to resolve, as well as sufficient time to complete the initial investigation.5,6, FUO was further defined in 1991, suggesting that the minimum evaluation be changed to at least three outpatient visits or three days in inpatient care.7 Others have proposed shorter lengths of time (e.g., two weeks, because today's patients present earlier and receive a diagnosis more quickly).8,9 A retrospective review of 226 hospitalized febrile patients examined the timing of diagnosis from initial visit for fever through the end of hospitalization.
