Accurate estimates of Mycobacterium tuberculosis (M.tb) infection in young children provide a critical indicator of on-going community M.tb transmission. Cross reactions due to infection with environmental mycobacteria and/or Bacille Calmette-Guérin (BCG) vaccination compromise the estimates derived from population-level tuberculin skin test surveys using traditional cut-off methods. Newer statistical approaches are prone to failure of model convergence, especially in settings where the prevalence of M.tb infection is low and environmental sensitisation is high...

Clear skeletal evidence of prehistoric tuberculosis (TB) is rare, especially in children. We describe and differentially diagnose the pathological changes displayed by a five-year-old child, Pollera 21 (PO21) dated to the Middle Neolithic of Liguria (Italy), or 5740±30 BP (Beta-409341; 6635-6453cal BP, 2σ, OxCal 4.2). PO21 shows a number of osteoarticular lesions, mainly of a lytic nature with very little bone proliferation: the vertebral column, the shoulder and pelvic girdles, and the ribcage are involved...

INTRODUCTION: Diagnosis of Tuberculosis (TB) in children is difficult because the clinical presentation is not specific, the chest X-ray interpretation has low accuracy and sputum sample is difficult to obtain. Antigen detection test such as rapid urine LAM is a non-invasive alternative for diagnosing TB . Lipoarabinomannan (LAM) is the main component of M.tuberculosis cell wall. AIM: To determine the diagnostic value of urinary LAM antigen for diagnosis of childhood TB...

BACKGROUND: Poorer virologic response to nevirapine- versus efavirenz-based antiretroviral therapy (ART) has been reported in adult systematic reviews and pediatric studies. METHODS: We compared drug discontinuation and viral load (VL) response in ART-naïve Ugandan/Zimbabwean children ≥3 years of age initiating ART with clinician-chosen nevirapine versus efavirenz in the ARROW trial. Predictors of suppression <80, <400 and <1000 copies/mL at 36, 48 and 144 weeks were identified using multivariable logistic regression with backwards elimination (P = 0...

Tuberculosis (TB) is a major public health problem, invading all age groups world-wide. It is an opportunistic infection affecting the individuals alone or with co-infections. Childhood TB is a neglected aspect and a significant health problem in epidemic areas. It constitutes more than 20% of TB incidence. Pediatric TB exists in the shadow of adult TB. The clinicians concentrate on pulmonary manifestation of TB, whereas it is a major problem in both pulmonary and extra-pulmonary infections. The rate of infection with this disease is mostly associated with poverty, social disruption and human immunodeficiency virus (HIV) infection...

Primary tuberculosis osteomyelitis of metacarpal bone is rare. The majority of cases occur in children and young adults and there is difficulty in diagnosis mainly in young children. We report a new case in children aged of 3 years, presenting a swelling on the dorsal side of her right hand since 8 months. X-ray showed an expansile, cystic and lytic lesion involving the little finger metacarpal. Tuberculosis was confirmed on histological examination. No lesions in lung parenchyma or lymphadenopathy were associated...

Tropical pulmonary eosinophilia (TPE) is an exaggerated immunological response to filarial antigens mainly seen in adults in endemic areas and is uncommonly reported in children. The diagnosis is frequently delayed as it mimics asthma clinically, while the chest radiograph might show miliary mottling which is often confused with that in pulmonary tuberculosis. A 5-year-old girl presented with episodes of nocturnal cough, wheeze, low grade fever and breathlessness for the previous 4 months and was being treated for asthma...

BACKGROUND: Following infection with Mycobacterium tuberculosis (M.tb), children are more susceptible to develop disease particularly extrapulmonary disease than adults. The exact mechanisms required for containment of M.tb are not known, but would be important to identify correlates of protection. OBJECTIVE: To comprehensively analyze key immune responses to mycobacteria between HIV-negative children with extrapulmonary TB (EPTB) compared to children with pulmonary TB (PTB) or healthy controls...

The incidence of drug-resistant tuberculosis (DR-TB) in pediatric populations is a critical indicator of national TB management and treatment strategies. Limited data exist regarding the rate of pediatric DR-TB. In this study, we aimed to analyze the status of DR-TB in Korean children from 2007 to 2013. We analyzed specimens submitted to the Korean Institute of Tuberculosis using Mycobacterium tuberculosis culture and drug susceptibility tests (DSTs) from January 2007 through December 2013. Specimens from patients ≤ 19 years of age were included...

PURPOSE: Tuberculosis (TB) remains a problem in the community. TB patients usually experience malnutrition, which is characterized by both decreased body weight (BW) and body fat percentage (BFP). Leptin, an important regulator of BW, also plays an important role in cellular immunity, which is integral to defense against Mycobacterium tuberculosis infection. We analyzed the effect of an anti-TB treatment regimen on the leptin level, BW, and BFP of children with TB. METHODS: The design of this study was a group interrupted time series...

OBJECTIVES: The diagnosis of pediatric tuberculosis (TB) presents many challenges, and is further complicated in HIV-infected patients. While many diagnostic systems have been proposed, there is no pediatric TB diagnosis gold standard. The outcomes of four TB diagnostic systems in HIV-infected children were compared in this study. METHODS: A retrospective cohort study was conducted at a TB/HIV reference hospital in Rio de Janeiro. HIV-infected pediatric patients evaluated for TB from 1998 to 2010 were reassessed using four diagnostic systems: Kenneth Jones, 1969; Tidjani, 1986; Ben Marais, 2006; Brazilian Ministry of Health, 2010...

INTRODUCTION: Lopinavir/ritonavir-based antiretroviral therapy (ART) is recommended for all HIV-infected children less than three years. However, little is known about its field implementation and effectiveness in West Africa. We assessed the 12-month response to lopinavir/ritonavir-based antiretroviral therapy in a cohort of West African children treated before the age of two years. METHODS: HIV-1-infected, ART-naive except for a prevention of mother-to-child transmission (PMTCT), tuberculosis-free, and less than two years of age children with parent's consent were enrolled in a 12-month prospective therapeutic cohort with lopinavir/ritonavir ART and cotrimoxazole prophylaxis in Ouagadougou and Abidjan...

Childhood tuberculosis (TB) is a significant global health burden. There are more than 1 million new cases of childhood TB annually. Despite this, many national TB control programs largely focus on identification and treatment of smear positive adults. Early case detection is essential if childhood TB is to be controlled and eradicated.Delayed diagnosis of TB is associated with more advanced disease and worse treatment outcomes. Younger children who go undiagnosed for long periods are at risk of developing severe pulmonary and extrapulmonary disease, such as meningitis...

BACKGROUND: The 2016 World Health Organization guidelines recommend all children <3 years start antiretroviral therapy (ART) on protease inhibitor-based regimens. But lopinavir/ritonavir (LPV/r) syrup has many challenges in low-income countries, including limited availability, requires refrigeration, interactions with anti-tuberculous drugs, twice-daily dosing, poor palatability in young children, and higher cost than non-nucleoside reverse transcriptase inhibitor (NNRTI) drugs. Successfully initiating LPV/r-based ART in HIV-infected children aged <2 years raises operational challenges that could be simplified by switching to a protease inhibitor-sparing therapy based on efavirenz (EFV), although, to date, EFV is not recommended in children <3 years...
