| Gaia: | The diagnosis of tuberculosis in the childhood population represents a major obstacle to the health system because the pediatric patient is paucibacillary. This is done by four classic criteria: epidemiological, tuberculinic, radiological and clinical; however, this method has an approximate sensitivity of 50%. On the other hand, molecular tests are new methods for the diagnosis and treatment of these infections, due to the rapidity of the result, high sensitivity, specificity and also, it reports resistance to antituberculosis drugs. Therefore, the objective of the review is to investigate the diagnosis of molecular methods in pediatric tuberculosis, since it is considered a vulnerable population, with more probability of disease progression, diagnostic problems due to the condition of being pediatric patients, the difficult microbiological isolation and therapeutic difficulties. Objective: describe the evidence on the use of molecular tests in the diagnosis of childhood tuberculosis in Latin American countries reported in the scientific literature. Materials and methods: a narrative review of the literature was performed. The selection criteria were articles that evaluated molecular tests in pediatric patients up to 18 years with a diagnosis of tuberculosis in Latin American countries. A structured search was conducted in Medline via OVID and Embase using the keywords “tuberculosis”, “pediatric”, “children”, “diagnosis” and “molecular”. The language was limited to English and Spanish, but there was no date limit. Results: 1050 articles were found, of which 751 articles were removed by the selection criteria in the title / summary and 95 articles in the full text. A qualitative analysis was performed with the 8 selected articles, which were published between 2003 and 2018, in addition 50 % of the articles were made in Peru. It was also found that the nested PCR test was implemented in 87.5 % of the studies and only 12.5 % used the GeneXpert MTB / RIF test. Most of the articles showed that nPCR has high specificity, but low sensitivity compared to liquid cultures. The nPCR has a tendency to have more false positives. Conclusions: although there are multiple molecular tests, only the report of the nested PCR test and GeneXpert MTB / RIF was found in the articles. There is little literature reported on the application of molecular diagnostic methods in the pediatric population for Latin America. |
