Laboratory findings of scrub typhus cases
| Laboratory findings | Patients (%) |
|---|---|
| AKI* (increase SCr > 1.5 times of normal level; N = 146) | 28 (19.2) |
| Renal at risk (increase SCr × 1.5 times of normal level) | 6 (4.1) |
| Renal injury (increase SCr × 2 times of normal level) | 7 (4.8) |
| Acute renal failure (increase SCr × 3 times of normal level or if baseline SCr > 4 mg/dL and increase SCr > 0.5 mg/dL) | 15 (10.3) |
| Abnormal chest radiograph findings (N = 142 cases) | 62 (43.6) |
| Bilateral interstitial infiltration | 36 (25.4) |
| Bilateral patchy consolidation | 6 (4.2) |
| Pulmonary edema | 6 (4.2) |
| Localized infiltration | 4 (2.8) |
| Unilateral pleural effusion | 2 (1.4) |
| Cardiomegaly | 8 (5.6) |
| Abnormal ECG findings (N = 79 cases) | 39 (49.4) |
| Sinus tachycardia | 17 (21.5) |
| Atrial fibrillation (new onset) | 9 (11.3) |
| Supraventricular tachycardia | 3 (3.8) |
| Nonspecific ST-T change | 3 (3.8) |
| Right bundle branch block | 3 (3.8) |
| Left anterior fascicular block | 1 (1.3) |
| Premature ventricular complex | 1 (1.3) |
| First degree AV block | 1 (1.3) |
| Complete heart block | 1 (1.3) |
AV = atrioventricular; AKI = acute kidney injury; ECG = electrocardiographic; SCr = serum creatinine.
*
For patients with unknown baseline creatinine level, the modification of Diet in Renal Disease equation was used to estimate renal function based on age, sex, and race.
