Abstract:
Objective:To analyze the clinical characteristics and prognosis of dengue fever inpatients in Guangzhou area, so that to provide references for clinical diagnosis and treatment.Methods:The demographic data, laboratory findings, clinical manifestations, and outcomes of 116 dengue fever cases admitted to Guangzhou Red Cross Hospital, Jinan University and the First Affiliated Hospital, Jinan University from August 1st to December 21st, 2024 were retrospectively analyzed.Results:Among the 116 patients, 99 cases (85.34%) were classified as non-severe dengue, while 17(14.66%) progressed to severe dengue (SD). The cohort was comprised of 62(53.45%) males and 54(46.55%) females, with an age of 63.5(22.0) years, and the hospitalization duration was 6(4) days, with the fever duration of 6(2) days. Sixty-two patients (53.45%) were complicated with comorbidities, among which hypertension (66.13%(41/62)), diabetes mellitus (25.81%(16/62)) and coronary atherosclerotic heart disease (22.58%(14/62)) accounted for the highest proportion. Primary clinical manifestations included fever (113 cases, 97.41%), with 86.21%(100/116) experiencing fever ≥five days, followed by fatigue (92 cases, 79.31%), myalgia (65 cases, 56.03%), anorexia (56 cases, 48.28%), cough/sputum (55 cases, 47.41%), and headache (54 cases, 46.55%). Early laboratory findings revealed leukopenia (2.22(1.75)×10 9/L], lymphopenia (0.63(0.50)×10 9/L), and thrombocytopenia (77.00(57.00)×10 9/L). Among 17 SD cases, 17 cases experienced severe organ damage, two cases had severe gastrointestinal bleeding, and two cases had septic shock. Among the patients with severe organ damage, there were eight cases of severe cardiac injury, followed by six cases of severe respiratory system injury, four cases of multiple organ dysfunction syndrome, three cases of acute kidney injury, three cases of neurological injury, and three cases of disseminated intravascular coagulation. Severe cardiac injury was manifested with acute heart failure in five cases, malignant arrhythmia in three cases, stress cardiomyopathy in one case, and acute myocardial infarction in one case. Severe respiratory system injuries were manifested with acute respiratory distress syndrome in five cases, severe pneumonia in three cases, and acute pulmonary embolism in one case. Neurological damage was manifested with viral meningitis in one case, acute cerebral infarction in one case, and sensorineural hearing loss in one case. All patients were cured or discharged after symptomatic supportive treatment and active prevention and treatment of complications. Conclusions:In 2024, dengue fever inpatients in Guangzhou area predominantly consist of elderly patients, who are complicated with comorbidities and present a high proportion of severe cases. Severe patients are primarily characterized by organ damage, with cardiovascular system injury being the most common severe manifestation. Dengue patients have a good prognosis.
