==Overview==
==Overview==
[[Tuberculosis]] in children aged 15 years or younger is considered a [[public health]] issue of special significance because it is a [[marker]] for recent [[Transmission (medicine)|transmission]] of TB. The likelihood of developing life-threatening forms of tuberculosis, such as [[miliary TB]] or [[TB meningitis]] is more in [[Infant|infants]] and young [[children]]. [[Screening]] in children is essential, because the [[signs]] and [[Symptom|symptoms]] are usually vague or non-specific.  History of close contact with [[tuberculosis]] patients plays an major role in the [[diagnosis]] of TB in children.  The [[treatment]] is similar to adults, with adjustment of the doses according to the child's weight.

===Diagnostic Algorithm===
==Diagnosis==
 
*Children must have a complete evaluation for tuberculosis, which includes a meticulous medical history, a complete physical examination, [[tuberculin skin test]] ([[TST]]), [[chest X-ray]], [[sputum]] or gastric aspirate studies ([[microscopy]] and culture), and [[HIV]] testing.
*Bacteriological testing might be difficult among children, but it should be performed whenever possible.
*Adolescents usually have the adult clinical presentation, but may also present with symptoms and findings seen in smaller children.
*Even though a scoring system has been developed in some countries<ref>{{Cite journal

*[[Empirical|Empirica]]<nowiki/>l treatment should be started and the regimen should be modified according to the [[DST]] ([[Drug susceptibility testing]]) results.
*Drug dosing should be calculated according to the child's weight, regardless the age.
*Pediatricians should closely monitor adverse drug reactions and manage them appropriately.
*For [[drug-resistant tuberculosis]], hospitalization is often required for the administration of IV medications.
*The treatment duration for drug-susceptible TB is 6 months.
*The treatment duration for drug-resistant tuberculosis will depend on the culture results. The duration of therapy should be at least 18 months after the culture is negative.
*Weight gain and resolution of symptoms are good markers for a good response to treatment.

<!---
Because of the high risk of disseminated tuberculosis in infants and children younger than 4 years of age, treatment should be started as soon as the diagnosis of tuberculosis is suspected. In general, the regimens recommended for adults are also the regimens of choice for infants, children, and adolescents with tuberculosis, with the exception that [[ethambutol]] is not used routinely in children. Because there is a lower bacillary burden in childhood-type tuberculosis there is less concern with the development of acquired [[drug resistance]]. However, children and adolescents may develop "adult-type" tuberculosis with upper lobe infiltration, cavitation, and [[sputum]] production. In such situations an initial phase of four drugs should be given until susceptibility is proven. When clinical or epidemiologic circumstances suggest an increased probability of [[INH]] resistance, [[EMB]] can be used safely at a dose of 15--20 mg/kg per day, even in children too young for routine eye testing. [[Streptomycin]], [[kanamycin]], or [[amikacin]] also can be used as the fourth drug, when necessary.
Most studies of treatment in children have used 6 months of [[INH]] and [[RIF]] supplemented during the first 2 months with [[PZA]]. This three-drug combination has a success rate of greater than 95% and an [[adverse drug reaction]] rate of less than 2%. Most treatment studies of intermittent dosing in children have used daily drug administration for the first 2 weeks to 2 months. DOT should always be used in treating children.
Because it is difficult to isolate ''M. tuberculosis'' from a child with pulmonary tuberculosis, it is frequently necessary to rely on the results of drug susceptibility tests of the organisms isolated from the presumed source case to guide the choice of drugs for the child. In cases of suspected drug-resistant tuberculosis in a child or when a source case isolate is not available, specimens for [[microbiological]] evaluation should be obtained via early morning [[gastric]] [[aspiration]], [[bronchoalveolar lavage]], or [[biopsy]].
In general, extrapulmonary tuberculosis in children can be treated with the same regimens as [[pulmonary]] disease. Exceptions are disseminated tuberculosis and tuberculous meningitis, for which there are inadequate data to support 6-month therapy; thus 9--12 months of treatment is recommended.
The optimal treatment of pulmonary tuberculosis in children and adolescents with [[HIV]] infection is unknown. The [[American Academy of Pediatrics]] recommends that initial therapy should always include at least three drugs, and the total duration of therapy should be at least 9 months, although there are no data to support this recommendation.

Overview

Tuberculosis in children aged 15 years or younger is considered a public health issue of special significance because it is a marker for recent transmission of TB. The likelihood of developing life-threatening forms of tuberculosis, such as miliary TB or TB meningitis is more in infants and young children. Screening in children is essential, because the signs and symptoms are usually vague or non-specific. History of close contact with tuberculosis patients plays an major role in the diagnosis of TB in children. The treatment is similar to adults, with adjustment of the doses according to the child's weight.

Diagnosis

  • Children must have a complete evaluation for tuberculosis, which includes a meticulous medical history, a complete physical examination, tuberculin skin test (TST), chest X-ray, sputum or gastric aspirate studies (microscopy and culture), and HIV testing.
  • Bacteriological testing might be difficult among children, but it should be performed whenever possible.
  • Adolescents usually have the adult clinical presentation, but may also present with symptoms and findings seen in smaller children.
  • Even though a scoring system has been developed in some countries[2][3][4][5][6], the WHO does not recommend this system for the evaluation of children with suspected TB.[1]
Diagnostic Approach in Children with Suspected Tuberculosis
History and Symptoms
Physical Examination
  • The physical examination might be unremarkable in children.
  • Extrapulmonary tuberculosis presents with abnormal physical findings.
Tuberculin Skin Test
  • Important for evaluating children with no history of close contact and to screen for TB infection.
  • In immunocompetent children, > 10 mm is considered positive.
  • In immunosuppressed children, > 5mm is considered positive.
Chest X-ray
  • Common findings include consolidation associated with an enlarged lymph node in the hilum.
Bacteriological Tests
  • Sputum or gastric aspirates should be assessed for the presence of M. tuberculosis.
  • Microscopy and culture should be done in every case possible to confirm the diagnosis.
HIV Test
  • In children with suspected TB, HIV testing should be offered.

Diagnostic Approach for Extrapulmonary Tuberculosis

Location Common Clinical Presentation Diagnostic Workup
Peripheral Adenopathy Painless lymph node enlargement, commonly in one side of the neck. Fine needle aspiration or biopsy of the lymph node, culture of aspirate.
Miliary Tuberculosis Lethargy, fever, non-specific symptoms. Order a chest X-ray and a lumbar puncture in suspicion of meningeal involvement.
Tuberculous Meningitis Lethargy, neck stiffness, headache, irritability, bulging fontanelle. Lumbar puncture, head CT.
Pleural Effusion Decreased breath sounds, dullness to percussion, chest pain. Order a chest X-ray, perform an analysis of the pleural fluid.
Tuberculous Peritonitis Order an abdominal ultrasound, consider abdominal fluid aspiration for analysis. Abdominal tenderness, ascites.
Bone or Joint Infection Altered ROM, joint swelling, monoarticular pain. X-ray of the affected limb, joint fluid aspiration and analysis.

  • Empirical treatment should be started and the regimen should be modified according to the DST (Drug susceptibility testing) results.
  • Drug dosing should be calculated according to the child's weight, regardless the age.
  • Pediatricians should closely monitor adverse drug reactions and manage them appropriately.
  • For drug-resistant tuberculosis, hospitalization is often required for the administration of IV medications.
  • The treatment duration for drug-susceptible TB is 6 months.
  • The treatment duration for drug-resistant tuberculosis will depend on the culture results. The duration of therapy should be at least 18 months after the culture is negative.
  • Weight gain and resolution of symptoms are good markers for a good response to treatment.
