INTRODUCTION: For adequate disease control the World Health Organization has proposed the diagnosis and treatment of latent tuberculous infection (LTBI) in groups of risk of developing the disease such as children. There is no gold standard (GS) test for the diagnosis of LTBI. The objective of this study was to estimate the prevalence of LTBI in young children in contact with a household case of tuberculosis (TB-HCC) and determine the accuracy and precision of the Tuberculin Skin Test (TST) and QuantiFERON-TB Gold in-tube (QFT) used in the absence of a GS...

INTRODUCTION: The National tuberculosis program (NTP) in Ivory Coast recommends that children under 5 years living in a family environment with contagious tuberculosis patients, should receive Prophylactic treatment with INH (PTI), whatever the result of the tuberculin skin test (positive or negative) and their BCG status (vaccinated or not), at a dose of 5mg/kg/day for 6 months. We conducted this study to check the implementation of this recommendation in three support services of tuberculosis in Abidjan, the economic capital...

BACKGROUND: Lower respiratory tract infection in children is increasingly thought to be polymicrobial in origin. Children with symptoms suggestive of pulmonary tuberculosis (PTB) may have tuberculosis, other respiratory tract infections or co-infection with Mycobacterium tuberculosis and other pathogens. We aimed to identify the presence of potential respiratory pathogens in nasopharyngeal (NP) samples from children with suspected PTB. METHOD: NP samples collected from consecutive children presenting with suspected PTB at Red Cross Children's Hospital (Cape Town, South Africa) were tested by multiplex real-time RT-PCR...

Since the global Expanded Program on Immunization (EPI) was launched in 1974, vaccination against six diseases (tuberculosis, polio, diphtheria, tetanus, pertussis, and measles) has prevented millions of deaths and disabilities (1). Significant advances have been made in the development and introduction of vaccines, and licensed vaccines are now available to prevent 25 diseases (2,3). Historically, new vaccines only became available in low-income and middle-income countries decades after being introduced in high-income countries...

In this review, reports were retrieved in which vitamin D status, as assessed by serum 25-hydroxyvitamin D [25(OH)D] levels, was measured in South African population groups with varied skin colours and ethnicities. Healthy children and adults were generally vitamin D-sufficient [25(OH)D level >50 nmol/L] but the majority of those aged above 65 years were deficient. A major role for exposure to solar ultraviolet radiation (UVR) in determining 25(OH)D levels was apparent, with the dietary contribution being minor...

Rapid and accurate diagnosis is critical for timely initiation of anti-tuberculosis (TB) treatment, but many people with TB (or TB symptoms) do not have access to adequate initial diagnosis. In many countries, TB diagnosis is still reliant on sputum microscopy, a test with known limitations. However, new diagnostics are starting to change the landscape. Stimulated, in part, by the success and rollout of Xpert MTB/RIF, an automated, molecular test, there is now considerable interest in new technologies. The landscape looks promising with a pipeline of new tools, particularly molecular diagnostics, and well over 50 companies actively engaged in product development, and many tests have been reviewed by WHO for policy endorsement...

BACKGROUND: Langerhans cell histiocytosis (LCH), typically found in children, is a rare single or multisystem disorder with a wide range of clinical and radiological manifestations. Unusual presentations of LCH are occasionally encountered and it may be difficult to distinguish LCH from an infection or a benign or malignant tumor. RESULTS: A 35-year-old female presented with pain in her back and left buttock, malaise, and weight loss, with a duration of several months...

Globally there is a burgeoning epidemic of drug mono-resistant tuberculosis (TB), multi-drug-resistant TB (MDR-TB), and extensively drug-resistant TB (XDR-TB). Almost 20% of all TB strains worldwide are resistant to at least 1 major TB drug including isoniazid. In several parts of the world there is an increasing incidence of MDR-TB, and alarmingly almost a third of MDR-TB cases globally are resistant to either a fluoroquinolone or aminoglycocide. This trend cannot be ignored because DR-TB is associated with greater morbidity compared to drug-sensitive TB, it accounts for almost 25% of global TB mortality, is extremely costly to treat, consuming substantial portions of budgets allocated to national TB programmes in TB endemic countries, and is a major threat to healthcare workers who are already in short supply in resource-poor settings...

Paradoxical immune reconstitution inflammatory syndrome is a well-described entity even in immunocompetent children, principally in association with Mycobacterium tuberculosis infections. Central nervous system involvement is a potential life-threatening form, sometimes refractory to standard treatment. We report the case of an HIV-negative refugee teenager, who presented with brain tuberculomas and pseudoabscesses responsive only to thalidomide.

BACKGROUND: Children are at higher risk of tuberculosis (TB) dissemination and extrapulmonary disease, contributing greatly to TB-associated morbidity and long-term sequelae. However, there are very few studies that assess the impact and clinical spectrum of pediatric extrapulmonary TB (EPTB) in low-prevalence regions. METHODS: Children <18 years of age diagnosed with TB in Madrid region (2005-2013) were reviewed. We compared the epidemiology, clinical characteristics and the performance of diagnostic tests in childhood extrapulmonary and pulmonary disease...

Tuberculosis is a pulmonary disease with an especially high mortality rate in immuno-compromised populations, specifically children and HIV positive individuals. The causative agent, Mycobacterium tuberculosis (Mtb), is a very slow growing and difficult organism to work with, making both diagnosis and development of effective treatments cumbersome. We utilize a fiber-optic fluorescence microendoscope integrated with a whole-body imaging system for in vivo Mtb detection. The system exploits an endogenous enzyme of Mtb (β-lactamase, or BlaC) using a BlaC-specific NIR fluorogenic substrate...

BACKGROUND: The diagnostic accuracy of Quantiferon-TB Gold In-Tube (QFT-IT) is uncertain in the pediatric population, while tuberculin skin test (TST) is still conventionally used despite its limitations. The aim of this study was to compare the performance of QFT-IT with TST in a large cohort of children screened for TB infection because of contact tracing, suspected TB, arrival from endemic country or immunosuppressive therapy. METHODS: A retrospective analysis was conducted on 517 children 0-14 years of age evaluated at the pediatric unit of the S...
