SETTING: Interferon-gamma (IFN-γ) release assays (IGRAs) play an important role in the diagnosis of Mycobacterium tuberculosis infection. However, in children with tuberculosis (TB), some studies have shown increased frequencies of false-negative or indeterminate IGRA results. OBJECTIVE: To analyse the spectrum of different cytokines to improve the diagnostic accuracy of IGRAs in latent tuberculous infection (LTBI) and active TB. DESIGN: We performed multiplex cytokine expression analysis of QuantiFERON® Gold In-Tube supernatants in children with active TB (n = 21) and disease-free contacts with (n = 15) and without LTBI (n = 12), to determine the sensitivity and specificity of the modified tests...

We aimed to estimate the burden of serious fungal infections in Egypt, currently unknown, based on the size of the populations at risk and available epidemiological data. Data were obtained from the World Health Organization (WHO), the Joint United Nations Programme on HIV/AIDS (UNAIDS), and published reports with clearcut denominators. When no data existed, risk populations were used to estimate frequencies of fungal infections, using previously described methodology. The population of Egypt in 2011 was ∼82,500,000; 31% children, and 8% women >60 years of age...

Children who are adopted internationally have an increased risk of infectious diseases due to endemic conditions and variable access to preventive health care, such as vaccines, in their country of origin. Pediatricians and other providers who care for children should be familiar with the recommended screening for newly arrived international adoptees. Testing for gastrointestinal pathogens, tuberculosis, hepatitis, syphilis, and HIV should be routinely performed. Other endemic diseases and common skin infections may need to be assessed...

Despite affecting men, women, and children for millennia, tuberculosis (TB) is the most neglected disease. In contrast, the global response to HIV has reached a defining moment. By uniting efforts, promptly integrating major scientific findings for both treatment and prevention, and scaling up services, the once inconceivable end to the HIV epidemic may no longer be an illusion. "The world has made defeating AIDS a top priority. This is a blessing. But TB remains ignored" - Nelson Mandela. While there is no doubt that revolutionary diagnostics and new and repurposed drugs have provided some hope in the fight against TB, it is evident that scientific advances on their own are inadequate to achieve the World Health Organization's ambitious goal to end TB by 2035...

The risk of TB among pediatric SOT recipients increases as the globalization of medical care continues to broaden. Unlike adults, children and especially infants are more susceptible to TB as a complication after transplantation. Little data exist regarding the true incidence of TB and the optimal risk-based management of this very vulnerable population. Here, we highlight the theoretical and practical issues that complicate the management of these patients and pose some questions that should be addressed when managing these patients...
