BACKGROUND: Despite antiretroviral therapy, it is generally believed that the risk for pneumococcal infections (PnIs) is high among patients infected with human immunodeficiency virus (HIV). However, most studies in this field have been conducted before 2010, and the proportion of virologically suppressed patients has drastically increased in these latter years thanks to larger indications and more effective antiretroviral regimens. This study aimed to re-evaluate the current risk of PnI among adult patients infected with HIV...

Community-acquired pneumonia (CAP) is associated with significant morbidity and mortality in Latin America and the Caribbean (LAC) region. Poverty, socioeconomic factors, and malnutrition influence the incidence and outcome of CAP in LAC. In LAC, Streptococcus pneumoniae is the most frequent microorganism responsible for CAP, (incidence: 24-78%); the incidence of atypical microorganisms is similar to other regions of the world. Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) is a growing problem in the LAC region, with the Caribbean being the second most affected area worldwide after Sub-Saharan Africa...

BACKGROUND: Streptococcus pneumoniae is a leading and serious coinfection in adults with human immunodeficiency virus (HIV) infection, particularly in Africa. Prevention of this disease by vaccination with the current 23-valent polysaccharide vaccine is suboptimal. Protein conjugate vaccines offer a further option for protection, but data on their clinical efficacy in adults are needed. METHODS: In this double-blind, randomized, placebo-controlled clinical efficacy trial, we studied the efficacy of a 7-valent conjugate pneumococcal vaccine in predominantly HIV-infected Malawian adolescents and adults who had recovered from documented invasive pneumococcal disease...

A serotype-specific urinary antigen detection (UAD) assay for 13 serotypes included in the pneumococcal conjugate vaccine (PCV13) was recently reported as a useful diagnostic tool for pneumococcal pneumonia. We aimed to assess the diagnostic accuracy of the UAD in HIV-infected South African adults. Urine specimens from a well-defined cohort of HIV-infected South African adults with pneumonia were evaluated retrospectively in the UAD assay. Pneumonia was considered pneumococcal if either sputum Gram stain, sputum culture, blood culture, or the immunochromatographic (ICT) BinaxNow S...

BACKGROUND: In addition to reducing Haemophilus influenzae type b (Hib) disease in vaccinated individuals, the Hib conjugate vaccine (HibCV) has indirect effects; it reduces Hib disease in unvaccinated individuals by decreasing carriage. Human immunodeficiency virus (HIV)-infected children are at increased risk for Hib disease and live in families where multiple members may have HIV. The aim of this study is to look at the impact of 2 doses of the HibCV on nasopharyngeal carriage of Hib in HIV-infected Indian children (2-15 years) and the indirect impact on carriage in their parents...

It is unclear whether HIV-infected individuals remain at higher risk of invasive pneumococcal disease (IPD) compared with HIV-uninfected individuals. We conducted a cohort study of HIV-infected and demographically matched HIV-uninfected adults within Kaiser Permanente Northern California during the period 1996-2011. We used Poisson models to obtain rate ratios (RRs) for incident IPD associated with HIV infection and other risk factors. Among 13,079 HIV-infected and 137,643 HIV-uninfected adults, the IPD rate per 100,000 person-years was 160 (n = 109 events) for HIV-infected and 8 (n = 75 events) for HIV-uninfected subjects, with an adjusted RR of 13...

BACKGROUND: Children hospitalized with culture-confirmed pulmonary tuberculosis (PTB) frequently present with acute symptoms, possibly because of superimposed pneumococcal pneumonia. We undertook a time-series analysis to determine whether routine immunization of children with pneumococcal conjugate vaccine (PCV) was temporally associated with changes in the incidence of hospitalization for PTB in South African children. METHODS: PCV was introduced in the South African public immunization program in April 2009, with coverage for the third dose of PCV of 10%, 64% and 89% in 2009, 2010 and 2011, respectively...

Infants born to human immunodeficiency virus (HIV) infected women are HIV-exposed but the majority remains uninfected [i.e., HIV-exposed uninfected (HEU)]. HEU infants suffer greater morbidity and mortality from infections compared to HIV-unexposed (HU) peers. The reason(s) for these worse outcomes are uncertain, but could be related to an altered immune system state. This review comprehensively summarizes the current literature investigating the adaptive and innate immune system of HEU infants. HEU infants have altered cell-mediated immunity, including impaired T-cell maturation with documented hypo- as well as hyper-responsiveness to T-cell activation...

The aim of this study was to compare the immunologic response to a prime-boost immunization strategy combining the 13-valent conjugate pneumococcal vaccine (PCV13) with the 23-valent polysaccharide pneumococcal vaccine (PPSV23) versus the PPSV23 alone in HIV-infected adults. HIV-infected adults were randomized to receive PCV13 at week 0 followed by PPSV23 at week 4 (n = 31, prime-boost group) or PPSV23 alone at week 4 (n = 33, PPSV23-alone group). Serotype specific IgG geometric mean concentration (GMC) and functional oposonophagocytic (OPA) geometric mean titer (GMT) were compared for 12 pneumococcal serotypes shared by both vaccines at week 8 and week 28...

Streptococcus pneumoniae infection is a predominant cause of bacterial infection in HIV-infected individuals. However, reported rates of pneumococcal vaccination with 23-valent polysaccharide vaccine (PPV23) are variable. We evaluated uptake of PPV23 in patients diagnosed with HIV between 1996 and 2012 (n = 507) in the United States Air Force, a centralized HIV program with free access to care including vaccines and medications. A total of 411 (81.1%) patients received at least 1 PPV23 dose. The PPV23 vaccination within 1 year of diagnosis was greater for those diagnosed between 2004 and 2012 (n = 184, 86%) compared with 1996 to 2003 (n = 104, 56...

INTRODUCTION: Pneumococcal infection is a leading cause of illness and death in HIV-infected adults. Current United States guidelines for HIV-infected adults recommend a single dose of the 13-valent pneumococcal conjugate vaccine (PCV-13) at any CD4 count and at least 1 y after receipt of the 23-valent pneumococcal polysaccharide vaccine (PPV). PPV is known to lead to hyporesponsiveness to subsequent pneumococcal vaccines for at least 1 y Whether PCV-13 would be more immunogenic if administered later after PPV receipt or at higher CD4 counts has not been tested...

UK guidelines for vaccinating HIV-infected adults against bacteria are based on limited data. We compared antibody responses between 211 HIV-infected and 73 HIV-uninfected adults vaccinated with pneumococcal polysaccharide (PPV) and Hib/meningococcal C glycoconjugate vaccines (Hib/MenC-TT). IgG responses to Hib/MenC-TT were not significantly different. PPV induced IgGs >1.3 μg/ml for 10/12 serotypes among HIV-uninfected, and 5/12 in HIV-infected participants. HIV-uninfected adults had higher post-vaccination IgGs than HIV-infected for 4/12 serotypes (p<0...

BACKGROUND: The number of aging human immunodeficiency virus-infected (HIV+) individuals living in the United States has substantially grown over the past two decades. Advanced age and HIV infection both increase susceptibility to Streptococcus pneumoniae infection due to B cell dysfunction. The combined impact of these factors on pneumococcal vaccine responses remains unknown. METHODS: We assessed serum immunoglobulin (Ig) G and IgM levels and opsonophagocytic killing assay (OPA) titers to pneumococcal serotypes 14 and 23F in HIV+ subjects and HIV-uninfected (HIV-) controls 50-65 years old...
