A 6-year-old child with a new diagnosis of perinatal human immunodeficiency virus infection

Perinatal human immunodeficiency virus transmission, while rare in the United States, should be considered in children with a history of recurrent infections, chronic respiratory symptoms and developmental delay. A delayed diagnosis of human immunodeficiency virus in children can lead to significant morbidity and mortality. We present a 6-year-old male who presented for evaluation and management of antibiotic refractory chronic cough and purulent nasal secretions, with a history of recurrent bacterial pneumonias and sinus infections, disseminated varicella zoster, and global developmental delay. He likely had perinatally acquired human immunodeficiency virus. At the time of his human immunodeficiency virus diagnosis, he met the criteria for acquired immunodeficiency syndrome and was ultimately diagnosed with lymphocytic interstitial pneumonia (LIP). Our case illustrates the importance of universal human immunodeficiency virus screening of pregnant women, consideration of human immunodeficiency virus, and the prompt initiation of treatment. We believe this case serves as an important reminder for all medical providers who care for pregnant women and children

Changing Trends in Complications and Mortality Rates Among US Youth and Young Adults With HIV Infection in the Era of Combination Antiretroviral Therapy

Background. Combination antiretroviral therapy (cART) has resulted in a dramatic decrease in human immunodeficiency virus (HIV)–related opportunistic infections and deaths in US youth, but both continue to occur. Methods. We estimated the incidence of complications and deaths in IMPAACT P1074, a long-term US-based prospective multicenter cohort study conducted from April 2008 to June 2014. Incidence rates of selected diagnoses and trends over time were compared with those from a previous observational cohort study, P219C (2004–2007). Causes of death and relevant demographic and clinical features were reviewed. Results. Among 1201 HIV-infected youth in P1074 (87% perinatally infected; mean [standard deviation] age at last chart review, 20.9 [5.4] years), psychiatric and neurodevelopmental disorders, asthma, pneumonia, and genital tract infections were among the most common comorbid conditions. Compared with findings in P219C, conditions with significantly increased incidence included substance or alcohol abuse, latent tuberculosis, diabetes mellitus, atypical mycobacterial infections, vitamin D deficiency or metabolic bone disorders, anxiety disorders, and fractures; the incidence of pneumonia decreased significantly. Twenty-eight deaths occurred, yielding a standardized mortality rate 31.5 times that of the US population. Those who died were older, less likely to be receiving cART, and had lower CD4 cell counts and higher viral loads. Most deaths (86%) were due to HIV-related medical conditions. Conclusions. Opportunistic infections and deaths are less common among HIV-infected youth in the US in the cART era, but the mortality rate remains elevated. Deaths were associated with poor HIV control and older age. Emerging complications, such as psychiatric, inflammatory, metabolic, and genital tract diseases, need to be addressed
