<human>: Dear Dr.,My name is Prashant Patil. I used to have multi resistance TB. And I need your help regarding this.  My TB history:APRIL 2004: first time detected, cough fever etc. first treatment  for 3 months and I feel ok. (i was in munich germany) MAY 2005: came back: was in hospital for 8 weeks in isolation, MTB detected, treatment with Anti MTB medicines (i was in munich germany)... Strptomycin, Cirpofloxin, ethanbutol taken for 1 yr. and 3 months around. APRIL 2008: TB came back with very badly.. cough, fever etc... dr. suggested medicine (H/R/E/S/LFX)..I feel good but have lymphnodes in stomach. The x rays were become stable. October 2009: I came back to germany and regular CT scan check up... nodes found not decreasing. I had no fever, no cough nothing, I was okay. German doctor said the infection is increasing better to make operation the left most infected part of small upper lobe in left side is removed. (hospitalization in germany 8 weeks) from sept 2009 I have taken following medicationstill jan 2011: Moxifloxacine 400 mg 1-0-0Pyrazinamide 500 mg 3-0-0strptomycine 1 g     1-0-0 (stopped after 2 months)Para aminosaliclic acid (PSA granuals) 0-0-1Benzbromaron        1-0-0Omeprazol 20 mg    0-0-1Terizidon                1-1-2zyvoxid                  1-0-0  (medications have many side effects, missmaneged some drug after 8 months) Problem of today:I did CT scan in jun 2010 and it looks stable... After 6 months in 4 jan 2011, I did again one CT scan and on left side of lung, the is very little growth of bacteria found. Now my german doctors are very confused. Activities from last few months :brochiascopy has been done the sputum has been taken...The result is negative no bacteria found after 8 weeks also and bronchoscopy result also negative.. no bacteira found after 8 weeks no growth... I need  right suggestion, there is very little growth in left lung but not detected for TB, is it any other bacteria or TB or what.. anything else! and its treatment.. Physically, I am healthy. Thanks you very much. Best regards,
<bot>: Thanks for your question on Chat Doctor. I can understand your concern. I have gone through the detailed history you have given. Your bronchoscopy was normal. Your sputum AFB culture is also negative. So no need to worry about tuberculosis at present. CT scan is most likely showing old healed lesions. Tubercular lesions on lung heal by fibrosis. And these healed areas are seen on chest x-ray and CT scan life long. Since you are asymptomatic, healthy and all your bacteriological tests are negative, no need to worry about active tuberculosis. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
