Common Clinical Problems in Children Living with HIV/AIDS: Systemic Approach

Clinical manifestations in children living with HIV/ AIDS differ from those in adults due to poorly developed immunity that allows greater dissemination throughout various organs. In developing countries, HIV-infected children have an increased frequency of malnutrition and common childhood infections such as ear infections, pneumonias, gastroenteritis and tuberculosis. The symptoms common to many treatable conditions, such as recurrent fever, diarrhea and generalized dermatitis, tend to be more persistent and severe and often do not respond as well to treatment. The use of Anti Retroviral Therapy (ART) has greatly increased the long term survival of perinatally infected children so that AIDS is becoming a manageable chronic illness. As the immunity is maintained, the incidence of infectious complications is declining while noninfectious complications of HIV are more frequently encountered. Regular clinical monitoring with immunological and virological monitoring and the introduction of genotypic and phenotypic resistance testing where resources are available have allowed for dramatically better clinical outcomes. However, these growing children are left facing the challenges of lifelong adherence with complex treatment regimens, compounded by complex psycho-social, mental and neuro-cognitive issues. These unique challenges must be recognized and understood in order to provide appropriate medical management.     

Vertical Transmission of HIV–An Update

One of the greatest successes in AIDS research to date has by far been the discovery of successful interventions that interrupt the transmission of HIV from mother to child. It is however important to note that these successes have occurred largely in countries with great resources and the least burden of perinatal transmission of HIV. In the developing world wherein currently 95% of vertical transmission of HIV occurs, it is highly condemnable that still every minute an infected infant is said to be born in spite of the fact that vertical transmission is largely preventable, mainly because translating knowledge into practice is not always possible or feasible; This has led to a continuous growing numbers of children with HIV, thereby making pediatric HIV a looming problem rapidly draining the already burdened health care system of these countries. It is the need of the hour to appropriately address the challenges to achieve zero percent transmission of HIV from an infected mother to her child thereby giving a hope for an AIDS-free new generation worldwide.     

Risk Factors for Varicella Susceptibility Among Refugees to Toronto,Canada

Several outbreaks of varicella have occurred among refugees. We aimed to estimate the prevalence of varicella susceptibility among refugees, and identify risk factors for varicella susceptibility. All refugees rostered at Crossroads Clinic in Toronto, Canada in 2011–2014 were included in our study. Varicella serology was assessed at the initial visit. Refugees’ age, sex, education, time since arrival, and climate and population density of birth country were abstracted from the chart. Multivariate logistic regression was used to identify risk factors for varicella susceptibility. 1063 refugees were rostered at Crossroads Clinic during the study; 7.9 % (95 % CI 6.1, 9.7) were susceptible to varicella. Tropical climate (OR 3.20, 95 % CI 1.53, 6.69) and younger age (OR_{per year of age} 0.92, 95 % CI 0.88–0.96) were associated with increased varicella susceptibility. These risk factors for varicella susceptibility should be taken into account to maximize the cost-effectiveness of varicella prevention strategies among refugees.
