Jong An Lee, Kab Deuk Kim, Hwa Sik Song
ABSTRACT
BACKGROUND: Tsutsugamushi disease, Leptospirosis, and Hemorrhagic fever with renal syndrome(HFRS) are an acute febrile illness of autumn-winter type which are characterized by fever, headache, myalgia in acute stage. We reported the clinical and laboratory characteristics of 49 cases under investigation far febrile illness in rural communities of Korea in order to differentiate the diagnosis among Tsutsugamushi disease, Leptospirosis, and HFRS.
METHODS:
This study was done retrospectively by investigation of patient's age, occupation, symptom, laboratory findings and chest X-ray findings of Tsutsugamushi disease, Leptospirosis, and HFRS. All patients was seen in our hospital between September and November in 1997 and 1998 consecutive year.
RESULTS:
The most characteristic symptoms and signs of Tsutsugamushi disease were eschar(90.1%), and skin rash(70%). The epidemiological and laboratory characteristics of Tsutsugamushi disease were age 40 or more, farmer(90.1%), s-GOT(serum glutamic oxaloacetic transaminase) and s-GPT(serum glutamic pyruvic transaminase) elevation. The most characteristic symptoms and signs of Leptospirosis were sputum and cough(75%). The epidemiological and laboratory characteristics of Leptospirosis were all farmers(100%), hyperbilirubinemia(1.67 mg/dl). The most characteristic symptoms and signs of HFRS were gastrointestinal disturbance(100%), flank pain(66.7%). The epidemiological and laboratory characteristics of HFRS were leukocytosis, thrombocytopenia, azotemia, proteinuria (91.6%), and hematuria (83.3%).
CONCLUSION:
As the clinical feature, presence of eschar and skin rash were suggestive of Tsutsugamushi disease. As the clinical feature, presence of cough and sputum and laboratory finding such as elevation of bilirubin level were suggestive of Leptospirosis. As the clinical feature, presence of gastrointestinal disturbance, flank pain and laboratory finding of thrombocytopenia, and renal dysfunction were suggestive of HFRS.
