RESUMO

Objective To study the clinical and immunologic features of 67 cases of patients with scrub typhus.Methods Epidemiological data,clinical manifestations,laboratory and image examination results and treatment of 67 cases of patients with scrub typhus hospitalized from January 2010 to December 2013 at the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed.Results Autumn-winter type scrub typhus was predominant in the 67 patents.The main clinical manifestations included hyperpyrexia (100%,67/ 67),eschar or ulcer (91.0%,61/67),rash (52.2%,35/67),lymphadenopathy (46.3%,31/67) and other non-specific symptoms.Laboratory test results:①80.6% (54/67) of the patients had normal or decreased white blood cell count,62.7% (42/67) of them with elevated lymphocytes (> 40%),thrombocytopenia was detected in 34.3% (23/67) of the patients,the lowest platelets count was 14 × 109/L.②14 of 17 cases (82.4%) had normal percentage of CD3+ T lymphocytes,CD8+ T lymphocytes increased in 16 of 17 cases (94.1%),while the percentage of CD4+ T lymphocytes (14 of 17,82.4%) and B lymphocytes (15 of 17,88.2%) decreased in most of the patients.③C reactive protein (CRP),ferritin and erythrocyte sedimentation rate (ESR) were elevated in 95.2% (59/62),93.8% (45/48) and 89.1% (49/55) of the patients,respectively.④Elevated alanine aminotransferase (77.6%,52/67) and aspartate aminotransferase (80.6%,54/67) were frequent findings.⑤94.6% (35/37) of the patients had increased adenosine deaminase.⑥ Antinuclear antibody was positive in 31.0% (13/42) patients.⑦Epstein-barr virus DNA was detected in 15.6% (7/ 45) cases,77.6% (38/49) was accompanied with chest radiographic abnormalities.Two cases had tuberculosis.All the patients recovered after therapy with doxycycline,levofloxacin or moxifloxacin.Conclusion Autumn-winter scrub typhus has typical clinical manifestations in the 67 patients,and it can cause patients' immune disorders.
