Transcript of "National guidelines on pediatric TB"

  1. 1. National guidelines on Pediatric TB : Diagnosis & Management Dr. Abhijeet
  2. 2. Updated based on the recent evidence andadvances in pediatric TB diagnosis andtreatment in consultation with IAPduringJanuary- February 2012.
  3. 3. Diagnosis of Pediatric TB• All efforts should be made to demonstrate bacteriological evidence in the diagnosis of pediatric TB.• Alternative specimens : (Gastric lavage, Induced sputum, broncho-alveolar lavage).
  4. 4. • Optimal strength of tuberculin : 2 TU (RT 23 or equivalent) to be used for diagnosis in children.• A positive Tuberculin skin test / Mantoux positive >=10 mm induration.
  5. 5. • No role for inaccurate/inconsistent diagnostics like serology (IgM, IgG, IgA antibodies against MTB antigens) , various in-house or nonvalidated commercial PCR tests and BCG test.• Loss of weight was defined as a loss of > 5% of the highest weight recorded in the past three months.
  6. 6. Diagnostic Algorithm for PTB
  7. 7. Algorithm for Lymph node TB
  8. 8. Intermittent versus Daily regimen:• The intermittent therapy will remain the mainstay of T/t• However, Among seriously ill ,severe disseminated disease or neurotuberculosis, the chances of vomiting or non-tolerance of oral drugs is high in the initial phase. - should be given daily supervised therapy during hospital stay.
  9. 9. Daily doses (mg per kg/day)• Rifampicin : 10-12 mg/kg (max 600 mg/day)• Isoniazid :10 mg/kg (max 300 mg/day)• Ethambutol :20-25mg/kg (max 1500mg/day)• PZA :30-35mg/kg (max 2000 mg/day)• Streptomycin: 15 mg/kg (max 1gm/day).
  10. 10. • After discharge :- thrice weekly DOT regimen
  11. 11. Newer Case definitions for pediatric TB patientsA. Failure to respond: - Who fails to have bacteriological conversion to negative status or fails to respond clinically or deteriorates after 12 weeks of compliant intensive phase. (Alternative diagnoses/ reasons for nonresponsiveness should be ruled out.)
  12. 12. B .Relapse : - A case of pediatric TB declared cured or completed therapy in past and now has (clinical or bacteriological) evidence of recurrence.C. Treatment after default : - A case of pediatric TB who has taken treatment for at least 4 weeks and comes after interruption of treatment for 2 months or more and has active disease (clinical or bacteriological).
  13. 13. D. Others : - For programmatic purposes of reporting, all types of retreatment cases where bacteriological evidence could not be demonstrated but decision to treat again was taken on clinical grounds would continue to be recorded and reported as “OTHERS” for surveillance purposes.
  14. 14. Treatment Catagories:• There will be only two treatment categories – 1. For treating ‘new’ cases 2. For treating ‘previously treated cases’.
  15. 15. Treatment Catagories
  16. 16. • Smear positive: Any sample (sputum, induced sputum, gastric lavage, broncho‐alveolar lavage) positive for acid fast bacilli.• New Case: A patient who has had no previous ATT or for less than 4 weeks.• Relapse: Patient declared cured/completed therapy in past and has evidence of recurrence.
  17. 17. • Treatment after Default: A patient who has taken treatment for at least 4 weeks and comes after interruption of treatment for 2months and has active disease.• Failure to respond: A case of pediatric TB who fails to have bacteriological conversion to negative status or fails to respond• Default : which do not fit the above definitions.
  18. 18. • TB Meningitis: During intensive phase of TB Meningitis, Injection Streptomycin is to be replaced byTab. Ethambutol• Extending intensive and continuation phase: Children who show poor or no response at 8 weeks of intensive phase should be given extension of IP for one more month. .
  19. 19. - In patients with TB Meningitis, spinal TB, miliary/disseminated TB and osteoarticular TB, the continuation phase shall be extended by 3 months making the total duration of treatment to a total of 9 months. - A further extension may be done for 3 more months in continuation phase (making the total duration of treatment to 12 months) on a case to case basis in case of delayed response and as per the discretion of the treating physician/ pediatrician
  20. 20. • TB preventive therapy: The dose of INH for chemoprophylaxis is 10 mg/kg (instead of currently recommended dosage of 5 mg/kg) administered daily for 6 months.• TB preventive therapy should be provided to:a. All asymptomatic contacts (under 6 years of age) of a smear positive case, after ruling out active disease and irrespective of their BCG or nutritional status.
  21. 21. b. Chemoprophylaxis is also recommended for all HIV infected children who either had a known exposure to an infectious TB case or are Tuberculin skin test (TST) positive (>=5mm induration) but have no active TB disease.
  22. 22. c. All Tuberculin positive children who are receiving immunosuppressive therapy (e.g.Children with nephrotic syndrome, acute leukemia, etc.)d. A child born to mother who was diagnosed to have TB in pregnancy should receive prophylaxis for 6 months, provided congenital TB has been ruled out. BCG vaccination can be given at birth even if INH chemoprophylaxis is planned.
  23. 23. When to suspect pulmonary TB?• Fever and / or cough of recent onset lasting for > 2 weeks should arouse suspicion of tuberculosis.• Cough persisting beyond 2 weeks• Recent unexplained loss of weight• History of exposure to an infectious TB patient (smear positive)
  24. 24. • Pneumonia not responding to antibiotic therapy .• Diagnosis is also more likely in presence of risk factors such as recent history of measles or whooping cough and immunocompromised state including steroid therapy.• Significant superficial lymphadenopathy
  25. 25. Extra-pulmonary Tuberculosis• TB lymphadenitis- progressive enlargement of lymph node for more than 2 weeks, firm, minimally tender or not tender,sometimes fluctuating, may be matted and may have chronic sinus formation.- Fine needle aspiration cytology (FNAC) is usuallyadequate for accurate diagnosis and it correlates well with biopsy in >90% of cases.
  26. 26. - Histopathologytypically shows necrosis and epitheloid granuloma.- When FNAC is inconclusive, biopsy isnecessary for confirmation of diagnosis
  27. 27. • Pleural Effusion - If chest X-ray is suggestive of pleural effusion, pleural aspiration should always be performed for biochemical, cytological and smear examination by ZN stain to confirm the diagnosis.
  28. 28. - Typically, a tubercular effusion fluid is straw colored (pus, if aspirated, is very rarely due to TB etiology) has large numbers of cells (predominantly mononuclear), with high proteins (>3g/dL). - Adenosine Deaminase (ADA) levels over 60 IU/L may be suggestive of tuberculousis
  29. 29. • Tubercular meningitis (TBM) - longer (>1 week) duration of fever, with vague CNS symptoms such as behavior changes, irritability, drowsiness, headache, vomiting and seizures. - Physical examination reveals typically global encephalopathy with focal deficits, hydrocephalus and movement disorder. - Risk factors for TBM include age < 5 years, contact with an adult suffering from tuberculosis, PEM grade III and IV, and HIV infection.
  30. 30. • Tuberculoma -Often seen in older children, it may present as a focal seizure or -symptoms and signs of raised intracranial tension with multiple localizing signs
  31. 31. Abdominal tuberculosis- mesenteric lymphadenopathy, intestinal disease, peritoneal involvement or systemic disseminated disease presenting as hepatosplenomegaly.- Large matted lymph node mass- The ascitic tap should always be done in such situations
