Patients with PTB had more frequent CRP levels >10 mg/L, anaemia, elevated ferritin, neutrophilia, high neutrophil/lymphocyte ratio, increased alkaline phosphatase, and lower albumin levels compared with Non-PTB patients, similar to data reported by others.5,35,36 However, our findings suggest elevated levels of CRP and alkaline phosphatase, with the presence of cavity on CXR, and lower occurrence of current MDD are associated with PTB. This evidence concerns the gene CRP and anemia.
