3. • HIV infection and malnutrition lower the body’s
defenses, and measles and whooping cough
temporarily impair the strength of the immune
system. In the presence of any of these conditions, TB
can develop more easily (WHO pocket book of
hospital care for children, 2013).

5. • TB is most often severe when it is located in the lungs,
meninges or kidney. Cervical lymph nodes, bones, joints,
abdomen, ears, eyes and skin may also be affected (WHO
pocket book of hospital care for children, 2013).

6. Signs and symptoms of TB
• Many children present only with failure to grow normally
• Weight loss
• prolonged fever and
• Cough for > 14 days
(WHO pocket book of hospital care for children, 2013).

7. History questions
• When it started
A history of:
• unexplained weight loss or failure to grow normally
• unexplained fever, especially when it continues for longer than 2 weeks
• chronic cough (i.e. cough for > 14 days, with or without a wheeze)
• exposure to an adult with probable or definite infectious pulmonary TB.
• History of BCG vaccine
• Ask about other danger signs.

8. Physical examination
• Fluid on one side of the chest (reduced air entry, stony dullness to
percussion).
• Enlarged non-tender lymph nodes or a lymph node abscess, especially in
the neck.
• Signs of meningitis, especially when these develop over several days and
the spinal fluid contains mostly lymphocytes and elevated protein.
• Abdominal swelling, with or without palpable lumps.
• Progressive swelling or deformity in the bone or a joint, including the spine.
(WHO pocket book of hospital care for children,
2013).

10. Laboratory value
• The diagnosis of TB in children can be very difficult owing to the wide
range of symptoms.
• Sputum cannot often be obtained from children and in any case it is
often negative even on culture. Symptoms in children are not typical.
• The diagnosis should therefore be based on clinical findings, family
history of contact with a smear positive case, X-ray examination and
tuberculin testing
4/5/2017 +255758061770 10
11. Tuberculin Testing
• The tuberculin skin test is valuable as a diagnostic tool in children, in child
who did not receive a BCG vaccine an induration of 10mm or more
interpreted as positive, if a child did receive a BCG, the induration should
be at least 15mm to be positive.
• Test may be negative in children with TB who have HIV/AIDS, miliary
disease, severe malnutrition or recent measles.
• Absence of a response does not exclude TB because individuals of the
condition above may not have sufficient immunity for a positive Mantoux
test despite active TB
(WHO pocket book of hospital care for children, 2013;Tanzania standard
treatment guideline, 2013).
4/5/2017 +255758061770 11
12. • Obtain a chest X-ray. A diagnosis of TB is supported when a chest X-
ray shows a miliary pattern of infiltrates or a persistent area of
infiltrate or consolidation, often with pleural effusion, or a primary
complex.

13. Treatment
• To reduce the risk for drug-induced hepatotoxicity in children, follow the
recommended dosages:
– Isoniazid (H): 10 mg/kg (range, 10–15 mg/kg); maximum dose, 300
mg/day
– Rifampicin (R): 15 mg/kg (range, 10–20 mg/kg); maximum dose, 600
mg/kg per day
– Pyrazinamide (Z): 35 mg/kg (range, 30–40 mg/kg)
– Ethambutol (E): 20 mg/kg (range, 15–25 mg/kg).
(WHO pocket book of hospital care for children,
2013).
4/5/2017 +255758061770 13
14. Management
• Monitoring
Confirm that the medication is being taken as instructed, by direct
observation of each dose. Monitor the child’s weight gain daily and
temperature twice a day in order to check for resolution of fever.
These are signs of response to therapy.
• When treatment is given for suspected TB, improvement should be
seen within 1 month. If this does not occur, review the patient, check
compliance, re-investigate and reconsider the diagnosis.
(WHO pocket book of hospital care for
children, 2013).
4/5/2017 +255758061770 14
15. • Children < 5 years of age who are household or close contacts of
people with TB and who, after an appropriate clinical evaluation, are
found not to have active TB should be given 6 months of isoniazid
preventive therapy (10 mg/kg/day, range 7–15 mg/kg, maximum dose
300 mg/day) (WHO pocket book of hospital care for children, 2013).
