Abstract
AIM Until now, the performance of interferon-γ release assay (IGRA) and Mantoux tests remains unclear in infant tuberculous meningitis (TBM). Therefore, a systematic review is performed to evaluate the sensitivity of IGRA and Mantoux tests for the diagnosis of infant TBM in low and intermediate tuberculosis (TB) burden countries, while following PRISMA. METHODS Several databases, including PubMed, EBSCO, Embase, Scopus, Web of Science, ClinicalTrials.gov, and Cochrane Central Register of Controlled Trials, were searched. Articles describing the results of IGRA or Mantoux tests among infant TBM were included for analysis. Data, such as age, sex, Mantoux test or IGRA, and cerebrospinal fluid (CSF) microbiological examinations (such as acid-fast bacilli (AFB) smear, TB PCR, and TB culture), were extracted from each study. RESULTS A total of 31 articles were enrolled for further analysis, including 48 cases. The mean age was 9.4 ± 5.8 months and boys accounted for 57.1% of infants (24/42). Mantoux test was positive in 57.4% (27/47) of tested infants and IGRA was positive in 77.8% (7/9) of infants. In addition, among the infants with confirmed TB, 18 (52.9%, 18/34) of them have positive Mantoux responses and 7 (20.0%, 7/35) have positive IGRA results. CONCLUSIONS In low or intermediate TB burden countries, the Mantoux test has a poor performance for diagnosing TBM among infants, and IGRAs appear to have a moderate sensitivity for the diagnosis of infant TBM.

Abstract
BACKGROUND Cerebrospinal fluid (CSF) examinations play an important role in the diagnosis of tuberculous meningitis (TBM). However, their yield in the diagnosis of infant TBM remains unclear. This scoping review aims to detail the role of CSF examination for the diagnosis of infant TBM. METHODS A comprehensive literature search of PubMed, EBSCO, Embase, Scopus, Web of Science, ClinicalTrials.gov, and Cochrane Central Register of Controlled Trials was performed to identify articles published prior to October 14th, 2021. Articles describing the results of CSF exanimations among infant TBM were eligible for inclusion. Data extracted from each study included age, sex, CSF microbiological evidence (such as AFB smear, TB PCR, and TB culture), and routine CSF examinations (such as appearance, red blood cell count, white blood cell count, protein, and glucose). RESULTS A total of 98 cases were included in the final analysis. The yield of microbiological methods was listed as follows: CSF AFB smear, 20.5% (9/44); CSF TB culture 47.5% (29/61); CSF TB PCR, 65.0% (26/40); the combination of them, 57.3% (47/82). According to Marais criteria, the positivities of CSF examinations were calculated as follows: WBC count (ref, 50-500/μL), 65.5% (55/84); lymphocyte predominance (ref, >0.5), 75.4% (49/65); total protein (ref, >100 mg/dL), 67.8% (59/87); glucose (ref, <2.2 mmol/L, or CSF/serum ratio < 0.5), 68.2% (58/85). CONCLUSIONS Our data demonstrated that routine microbiological tools for infant TBM diagnosis have a sensitivity ranging from 20.5% to 65.0%, and most CSF features are non-specific and insufficient to predict a diagnosis of infant TBM. Therefore, further effort is required to develop new tools for infant TBM diagnosis.Key messages: Routine microbiological tools (such as acid-fast bacilli smear, PCR, and culture) have an unsatisfactory sensitivity for infant TBM diagnosis, and most CSF features are non-specific and insufficient to predict a diagnosis of infant TBM. Therefore, further effort is required to develop new tools for infant TBM diagnosis.

Abstract
BACKGROUND Due to the lack of a standard case definifion and the diffuculty in estabilishing a definitive diagnsos, TB in children needs increasing attention by physicians caring for pediatric patients. Tuberculous meningitis (TBM) is the most serious form of extrapulmonary tuberculosis that is associated with significant morbidity and mortality rate in the pediatric age group, especially in infants. This descriptive study was conducted in an University hospital, at the South of Turkey, from May 1999 to May 2019. METHODS The hospital records of 26 TBM infant that was diagnosed at our hospital were retrospectively evaluated. The epidemiological findings (age, gender, family history of TB, tuberculin skin test results, status of BCG scaring), stage of TBM at admission and clinical, laboratory and radiological features were collected. RESULTS Of the 26 infants, 61.5% were male and mean age of the patients was 7,65±2,6 (range, 3-12 months). The history of close contact with an infected adult was encountered in 73.1% (19 infant) of the cases. Only 69.2% of the patients (18 case) had a BCG scar. The prodromal stage (period between the onset of symptoms to hospital admission) ranged from 4 days to 180 days (39±51.3). 2 cases were defined as stage I, 10 cases as stage II and 14 cases as stage III TBM. Only two patients were initially positive for PPD test. While no neurological findings were found in 2 patients (diagnosed as stage I), neurologic findings at the time of admission included increased intracranial pressure; alteration in consciousness (92.3%), seizures (88.4%), vomiting (61.5%) cranial nerve palsy (23%), irritability 19.2%, hemiplegia 15.3% and meningeal signs (7%, only 2 patients). The presence of hepatomegaly 26.9 % and/or splenomegaly 11.5 % and/or extrapulmonary lymphadenopathy 3.8 % in nearly half of the cases suggested that totally 42,2% of cases had disseminated of tuberculosis. On admission, 46.1% of the patients were noted to have hyponatremia. Microbiologic confirmation was established in eleven (42.3%) of the 26 infant. A positive CSF culture for Mtb and/or smear for AFB and/or PCR was obtained in only 5 (19.2%) patients, whereas 3 of the cases had accompaining gastric aspirate examination positivity. Pulmonary consolidation in 14 (53.8%) patients, miliary patern in 10 (41.6%) and pulmonary hilar lymphadenopathy in only 5 (20.8%) patients. 23 (88.4 %) had hydrocephalus, 15 (57.6 %) infarction, 10 (38.4 %) basilar meningitis and 9 (34.6%) tuberculomas. Empiric anti-tuberculosis treatment was instituted in all, at a median of 3 days (range 1-15 days) following admission. 8 (30.7%) died, 3 (11.5%) recovered completely, and 15 (57.6%) recovered with sequelae. 12 case (2 died) of the infants had required ventriculoperitoneal shunting. CONCLUSION As early diagnosis and specific treatment appears to prevent serious complications and reduce mortality, a high index of suspicion among pediatricians is especially required in an infant with an atypical picture suggestive of tuberculosis infection.

Epidemiological Trends in the Form of Childhood Tuberculosis in a Referral Tuberculosis Hospital in Shandong, China. BIOMED RESEARCH INTERNATIONAL 2020; 2020:6142567. [PMID: 32851083 PMCID: PMC7436284 DOI: 10.1155/2020/6142567] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Revised: 07/13/2020] [Accepted: 08/01/2020] [Indexed: 11/17/2022]
Abstract
Background In China, the prevalence of tuberculosis (TB) diseases and epidemiological trends in the TB forms among children are still unclear; a retrospective study was conducted aiming to assess it. Methods Between January 2007 and September 2020, 1577 consecutive childhood TB patients (aged ≤ 15 years) were included in the study. Data, including demographic information and underlying diseases, were collected from medical records. Then, patients were categorized and reported according to the anatomical site of TB disease. To analyze the epidemiological trends in the proportion of each form of TB disease, a linear-by-linear association was used, and a P value of <0.05 was considered to indicate that a significant change had occurred in the proportion of TB disease over the studied period. Results During the fourteen-year study period, a total of 1577 children patients were enrolled, including 954 boys (60.5%) and 623 girls (39.5%), with a mean age of 9.26 ± 5.18 years. Among the studied patients, 810 (51.4%) patients have pulmonary TB, 1137 (72.1%) have extrapulmonary TB, 372 (23.6%) have both conditions, and another 765 (48.5%) extrapulmonary cases presented in isolated form. Pleural TB (29.0%) and tuberculous lymphadenitis (23.7%) were the most frequent two forms of childhood TB. In addition, during the past decade, the proportions of pulmonary TB, pleural TB, and tuberculous lymphadenitis showed an increasing trend (all P < 0.05). However, no significant trends in the proportions of other forms of TB disease, such as extrapulmonary TB (P > 0.05), tuberculous meningitis (P > 0.05), endobronchial TB (P > 0.05), and disseminated TB (P > 0.05), were found. Conclusion Our findings suggest that childhood TB is facing new challenges, and the policy should be adjusted timely to fit the real situation.

Abstract
To achieve the End Tuberculosis (TB) Strategy, it is important to understand the characteristics of TB in China, which may provide the government with important clues for controlling TB by 2030. Data from the Global Burden of Disease Study 2015 (GBD 2015) and Institute for Health Metrics and Evaluation (IHME) were reviewed and analysed. The age-standardized death rate decreased by 83.79% [95% uncertainty interval (UI) 73.06–87.10] from 1990 to 2015. The age-standardized prevalence of TB in males decreased steadily by 33.88% (95% UI 29.35–37.67) but nearly increased by 6.24% (95% UI -2.02–15.07) in females from 1990 to 2015. Disability-adjusted life years (DALYs) were higher in males than in females, and the highest TB burden was found in the elderly (70+ years of age). Over the period 1990–2015, the attributable age-standardized DALY rates for smoking decreased by 12.98% (95% UI 2.40–24.27), but increased for alcohol use and high fasting plasma glucose (HFPG). Greater attention should be paid to females especially in the under 5 years of age group, and more latent reasons explaining TB DALYs should be explored in future studies.
