My father aged 68, has completed tb spine medications for 14 months. Its been 3 months that tb medications have been stopped after doctor confirmed that tb is cured. However, he suffered some other issues like visual blurriness from ethambutol and eye doctor is saying there is cataract and we need that operated. His creatinine is at 2.2 with elevated bun and blood urea. All blood work is good except platelets are low at 80. Hba1c - 5.5, fbs: 91. Pps: 146. Urine analysis shows no protein but pus cells loaded, blood, nitrite and bacteria. We did his kft every 3 months and it was moderately high for a year. Nephrologist thinks some repetitive kidney infection which he says can be cured. He is saying that because there is no protein in urine we can mostly say its not diabetic nephropathy. My father is regularly on glimy 1 mg, rosutor gold 20/75 and metxl 25 mg. I am worried if it is not tb resurfacing or if this is anything to do with diabetes though his sugar has been is very good control. Glocometer show fasting of 86 and pp: 100 on most days. Any suggestions or information would be helpful to take the right course of actions. Nephrologist asked for urine culture and fundus examination in view of diabetic retinopathy.
