Hi Dear !! Thanks for your query to HCM . Read and reviewed your query and health concerns. You seems to suffer from-TB lympadenitis. Please find replies to your queries as follows- 1) What is the chance of relapse Ans-1-With 18 mths of Dots treatment-you should have cured by this treatment.But in conditions of certain stress in life, which is out of hands of a common man,chances of recurring Glandular /or Lung Tb do exist. The cause for this relapse, is the weakened immunity,which leads to reactivation of some dormant bacteria,at the opportune time. Q-2) how can the patient be sure that the TB does not exist anymore Ans-2-IGRA blood test with gain of body weight and reduction in the lymphnode size,and lac of fever with increased appetite,are the signs of recovery.But practically-its not possible to be sure that the TB does not exist anymore.As one cant reach out the organisms burried in the fibrosed healed scars in lymphnodes.Being omnipresent,recurrence of TB cant be prevented in times of stress,when either the old dormant bacteria in patients body/ or from the outside aggravate the relapsing infection in TB. Except IGRA blood test-which indicates the active TB infection,there is no certain test to declare that the TB does not exist anymore.This declaration is subject to these practical limitations. Hence practically,those patient in whom the patient comes out of the symptoms of the disease and maintains the criteria of clinical recovery with weight gain and recovery of complaints,it is not certain to define and declare the total cure of EXtra-pulmonary lymphadenitis,by now with current techniques. Q- 3) Does the tB medication affect future pregnancy Ans-3-Its not the TB medication which affects the future pregnancy.ON the contrary, chances of having future pregnancy,after TB medication have increased comparatively.But in certain percentage, the failure is from the permanent changes which are out of correction tools either by medicines or by surgical correction of the anatomical barriers-like adhesiolysis. Q- 4) If someone who has completed TB medication happens to have a miscarriage could it be related/associated due to TB medication Ans-In the given scenario-Miscarriage is not related to TB medication as such,as the drug effects don t persist that long,and once the chance is taken for pregnancy,the drug effects are ruled out along with the general fitness of the body condition to sustain that pregnancy. Its the scarring and missed out unhealthy endometrium ,which could be the cause of the miscarriage in such cases-where the chance is taken for pregnancy.
