ROLE OF USG IN EARLY DETECTION AND PREDICTING SEVERITY OF DENGUE INFECTION

Background: Early detection and severity assessment are crucial for managing dengue fever. Ultrasound (USG) imaging can help identify key features such as capillary leakage and organ involvement, aiding in diagnosis and prognosis.

Aims: To correlate ultrasound findings with the severity of dengue infection. To evaluate USGs sensitivity in detecting early capillary leakage and its prognostic value.

Methods: The study involved 66 patients (40 males, 26 females aged 12-70) with serologically confirmed dengue, observed from August 2022 to October 2023. USG was performed within 3 days of fever onset and again after 1 week.

Results: Day 1-3: Gallbladder wall thickening (60.6%) and pericholecystic fluid were common. Pleural effusion (34.8%) was observed in milder cases. Day 7: Gallbladder wall thickening persisted in 89.4%. New findings included ascites (24.2%), bilateral pleural effusion (31.8%), and pericardial effusion (9.1%). Severe cases showed hepatomegaly and splenomegaly.

Conclusion: USG is a valuable tool for early detection and severity assessment of dengue fever. Key findings like gallbladder wall thickening and pleural effusion can help predict disease severity and guide clinical management.

研究背景：登革热的早期检测与病情严重程度评估对疾病管理至关重要。超声（Ultrasound, USG）成像可识别毛细血管渗漏、器官受累等关键特征，辅助临床诊断与预后判断。
研究目的：探讨超声检查结果与登革热感染严重程度的相关性；评估USG检测早期毛细血管渗漏的灵敏度及其预后价值。
研究方法：本研究纳入2022年8月至2023年10月期间随访的66例经血清学确诊的登革热患者，其中男性40例、女性26例，年龄区间为12至70岁。所有患者均于发热起病3天内完成首次超声检查，并于发病1周后复查超声。
研究结果：发病1~3天时，胆囊壁增厚（占比60.6%）与胆囊周围积液为常见超声表现；轻症患者中可见胸腔积液（占比34.8%）。发病7天时，89.4%的患者仍存在胆囊壁增厚；新增超声表现包括腹腔积液（占比24.2%）、双侧胸腔积液（占比31.8%）与心包积液（占比9.1%）；重症患者可出现肝大与脾大。
研究结论：USG是登革热早期检测与病情严重程度评估的有效工具；胆囊壁增厚、胸腔积液等关键超声表现可辅助预测疾病严重程度，指导临床诊疗决策。
