Subjects with any medical condition in the moment of the Enrollment Visit determined by laboratory tests, which is likely to significantly interfere in the clinical manifestation of CFS. Here are detailed some of these medical conditions: ? Serum AST, ALT, ALP or total bilirubin levels exceeding more than 1.5 times the upper limit of normal (ULN) for the expected normal range for the testing laboratory. ? Serum creatinine or urea levels exceeding more than 1.5 time the ULN for the expected normal range for the testing laboratory. ? Serum CK totals levels exceeding the ULN for the expected normal range for the testing laboratory. ? Serum TSH levels exceeding the ULN for the expected normal range for the testing laboratory. ? Serum title of ANA exceeding 1:160 dilutions. ? Positive serum FR as per positivity criteria established for the testing laboratory. 9. Subjects suffering from a disease or medical condition that could increase associated risks to subjects? participation in the clinical trial, or interfere with the interpretation of the study results, and according to the investigator?s criteria, it would be inappropriate for the subjects? participation in the clinical trial. These diseases include, but are not limited to major depressive disorders with psychotic or melancholic features as bipolar disorders, schizophrenia, dementia, anorexia or nervous bulimia. 10.
