Blood sugar, blood urea nitrogen (BUN), creatinine, sodium, potassium, calcium, magnesium, phosphorus, rheumatologic tests, HBS antigen, anti-HCV antibody, anti-HAV antibody (IgM), anti-HIV antibody, and urinalysis were negative or within the normal ranges all the time. AST: aspartate aminotransferase; ALT: alanine aminotransferase; ALP: alkaline phosphatase; ESR: erythrocyte sedimentation rate; WBC: white blood cell; HB: hemoglobin; MCV: mean corpuscular volume; MCH: mean corpuscular hemoglobin; MCHC: mean corpuscular hemoglobin concentration; RDW-CV: red cell distribution width-coefficient of variation; PLT: platelet.
