In HIV-endemic regions, maternal HIV-exposed but HIV-uninfected infants, which is the majority of children affected by HIV, also show poor growth and increased morbidity. Although nutrition has been examined, the effects of HCMV infection have not been evaluated. We studied the effects of HCMV infection on the growth, development, and health of maternally HIV-exposed and unexposed infants in Zambia.</p><p><bold><italic>Methods.</italic></bold> Infants were examined in a cohort recruited to a trial of micronutrient-fortified complementary foods.

It is mainly a pathogen in an immunocompromised setting, particularly for human immunodeficiency virus (HIV)/AIDS and transplantation patients, where HCMV can reactivate. HCMV is the main infectious cause of mental retardation and neurodevelopmental impairment in neonates; this includes hearing loss, chiefly from congenital infection in utero [<xref ref-type="bibr" rid="bib1">1</xref>–<xref ref-type="bibr" rid="bib4">4</xref>]. In transplantation patients, HCMV-associated pneumonitis has a high mortality rate that is controlled primarily with ganciclovir. Prior to antiretroviral therapy (ART) in adult HIV/AIDS patients, HCMV was a major opportunistic infection that correlated with retinitis, leading to blindness as well as disseminated infections and in turn mortality [<xref ref-type="bibr" rid="bib5">5</xref>]. In childhood HIV, HCMV coinfection can be particularly severe; studies in the United States showed increased neurological disease, AIDS progression, and mortality [<xref ref-type="bibr" rid="bib6">6</xref>, <xref ref-type="bibr" rid="bib7">7</xref>]. In HIV-endemic sub-Saharan Africa, pediatric ART is restricted and HCMV complications are only beginning to be addressed; even the extent of HCMV effects on the general child population has not been established. In Kenyan infants, HIV infection was associated with impaired control of HCMV replication [<xref ref-type="bibr" rid="bib8">8</xref>]. In Zambia, autopsy studies of HIV-positive children who died from respiratory disease identified HCMV as a frequent infection, often together with tuberculosis [<xref ref-type="bibr" rid="bib9">9</xref>, <xref ref-type="bibr" rid="bib10">10</xref>].</p><p>HCMV may also affect infants born to HIV-positive mothers, even if the infants remain HIV-negative. HIV-positive mothers can have reduced maternal passive immunity to protect their infants against HCMV disease. This includes protective cytokines or antibodies, immunoglobulin G (IgG) transcytosed across the placenta in utero to the fetus, or immunoglobulin A (IgA) secreted in breast milk to protect against gut infection in the newborn. Moreover, immunosuppression in the HIV-positive mother can lead to increased HCMV levels due to reactivation or secondary infection. Little is known about how these effects impact childhood HCMV in HIV-endemic African populations. The number of children who are maternally HIV exposed but not infected is increasing due to the epidemic spread of HIV and also ART introduction to decrease mother-to-child HIV transmission.</p><p>We previously reported that in Zambia, where HIV is endemic, children are exposed to a complex collection of HCMV strains, as exists elsewhere, but also show increased prevalence of higher loads transmitted from HIV-positive mothers [<xref ref-type="bibr" rid="bib10">10</xref>]. HIV-exposed infants do not grow as well as unexposed infants, have increased morbidity, and are particularly vulnerable when they transition from breastfeeding [<xref ref-type="bibr" rid="bib11">11</xref>, <xref ref-type="bibr" rid="bib12">12</xref>]. Here we report the effects of HCMV infection on growth, development, and health of HIV-exposed and unexposed infants in Zambia who were recruited to a double-blind, randomized controlled trial of micronutrient-fortified infant foods [<xref ref-type="bibr" rid="bib13">13</xref>]. The results identify HCMV as a pathogen associated with poor development including evidence of increased morbidity, irrespective of diet.</p><sec sec-type="methods"><title>METHODS</title><sec><title>Study Design, Population, and Recruitment</title><p>A total of 811 infants were recruited for a trial of micronutrient-fortified complementary foods.

Qualitative and quantitative polymerase chain reaction (PCR) was performed on DNA extracted from 200 μL of sera using the QIAamp DNA Blood Mini Kit (Qiagen). PCR was used to amplify HCMV glycoprotein gB (UL55), as described previously [<xref ref-type="bibr" rid="bib10">10</xref>], with baseline and high-load cutoff sensitivities of 50 and 1000 copies/mL of sera, respectively.</p></sec><sec><title>Morbidity Assessments</title><p>The clinical officer (J.

Prescriptions for antibiotics or antimalarials were provided at the study clinic. Hospital referrals were defined as those made to the local tertiary facility (UTH), with severe symptoms (inability to drink or breastfeed, severe vomiting, convulsions, respiratory distress, loss of consciousness, or severe lethargy), for surgery, or with an illness requiring consultation with a specialist.</p></sec><sec><title>Bayley Testing of Development</title><p>Child development tests were administered by 2 trained psychologists using Bayley scales of infant development (BSID II). The mental development index (MDI) and psychomotor development index (PDI) were used as standardized in the United States [<xref ref-type="bibr" rid="bib14">14</xref>] and age-normalized to a population mean of 100 and SD of 15. Some items were adapted to local settings (doll appearance or house pictures) while keeping underlying constructs. The test was translated to local languages (Bemba and Nyanja). If a child was sick at the time of assessment, the mother was asked to bring the child back 1–2 weeks after recovery. For logistical reasons, testing was conducted on a subset, including all with HIV-positive mothers and alternate infants with HIV-negative mothers.</p></sec><sec><title>Statistical Analysis</title><p>Growth and reported illness were compared between infants with and without HCMV using χ<sup>2</sup> tests. The impact of HCMV infection on length-for-age (LAZ), weight-for-age (WAZ), head circumference-for-age (HCZ), and arm circumference-for-age (ACZ) <italic>z</italic> scores at 18 months was analyzed as a continuous variable using linear regression and 95% confidence intervals (CIs) for regression coefficients. The impact on incidence of severe morbidity, defined as hospital referral or death, was estimated using rate ratios (RRs) and 95% CIs obtained using random-effects Poisson regression to account for repeated referrals among infants. Any planned surgeries were excluded (5 circumcisions, 4 hernias, and 4 other congenital abnormalities). It was decided a priori to perform analyses stratified by maternal HIV status; this excluded the 70 infants of HIV-unknown women. Maternal education, socioeconomic status (SES), and diet intervention arm were determined a priori as potential confounders. Adjustments were made for these a priori confounders as well as for breastfeeding duration (shorter or longer than 6 months), which was determined to be associated with HCMV infection in risk factor analyses. SES was measured by an asset index, as described previously [<xref ref-type="bibr" rid="bib13">13</xref>]. Interobserver reliability of the Bayley test was obtained in 663 testing sessions during which the same child was scored by the 2 psychologists. The intraclass correlation coefficient (ICC) of the scores was calculated using 1-way analysis of variance. A good agreement between scorers was found for both MDI (ICC = 0.91 [95% CI, .89–.92]) and PDI (ICC = 0.91 [95% CI, .90–.92]). MDI and PDI scores were analyzed as continuous variables and checked for normality on a normal probability plot. The association of Bayley test scores and HCMV seropositive antibody at 18 months was examined using linear regression with subsequent adjustment for SES, mother’s education, diet intervention arm, and breastfeeding duration. A 2-sided <italic>P</italic> value ≤.05 was considered statistically significant. Stata software (version 11.1, StataCorp) was used in all analyses.</p></sec><sec><title>Multiple Imputation Analyses</title><p>Among the 811 children enrolled in the study, 561 (69%) were available for HCMV DNA at 6 months, 430 (53%) for HMCV DNA at 18 months, and 460 (57%) for HCMV antibody at 18 months. Any missing data were mainly due to limitations on the infant serum sample volume after the large number of previous metabolic assays, which were used to interpret the primary outcome analyses, as described [<xref ref-type="bibr" rid="bib13">13</xref>]. Ninety samples were missing due to participant withdrawal from the study. In order to account for infants who were missing data, we used multiple imputations with chained equations methods using Stata software. Factors predictive of missing data (small child), risk factors for HCMV (mother’s education, SES, breastfeeding duration, and maternal HIV status), and the micronutrient diet intervention arm were used to impute 10 data sets. All continuous variables used in the imputation were normally distributed; SES and mother’s education were treated as ordered categorical variables. In addition to the main analyses of observed data, complete analyses were conducted with all imputed data.</p></sec><sec><title>Ethics</title><p>The study received approval from the ethics committees of the University of Zambia and the London School of Hygiene and Tropical Medicine.

The antibody was used to measure infection occurring in the cohort by 18 months; the DNA assay detects HCMV viremia on recruitment at 6 months, either primary or earlier, uncontrolled infections.</p><p>Among all children there was no significant effect of HCMV viremia on growth from age 6 months to 18 months. However, when the population was stratified for maternal HIV exposure, there were significant associations, but in opposing directions (<xref ref-type="table" rid="tbl1">Table 1</xref>). Among HIV-exposed children with HCMV viremia at 6 months, there was reduced LAZ (<italic>P</italic> = .04), with evidence for interaction of HCMV viremia with maternal HIV on LAZ (interaction, <italic>P</italic> = .007). Similar but nonsignificant directions were seen for WAZ and HCZ. With multiple imputations, the effect on LAZ in HIV-exposed infants remained (regression coefficient of −0.40 to −0.28; interaction, <italic>P</italic> = .07).

sec-type="discussion"><title>DISCUSSION</title><p>The results show that HCMV is a widespread pathogen that affects healthy growth and development of infants in Zambia. In the maternally HIV-exposed infants, HCMV infection was also associated with increased prevalence of stunting, reduced head size, and decreased psychomotor development. Previous analyses of this cohort showed that reduced growth in the HIV-exposed infants was unaffected by micronutrient fortification but was affected by socioeconomic factors [<xref ref-type="bibr" rid="bib13">13</xref>, <xref ref-type="bibr" rid="bib16">16</xref>]. The effects of HCMV on growth were also influenced by socioeconomic factors; however, the effects still existed after adjustments were made for socioeconomic factors, education level, breastfeeding duration, and diet. In Zambia we showed that HCMV infections occurred earlier, that is, during infancy, and were more prevalent (83% IgG seropositive in this cohort) than in many other geographic regions. Therefore, effects of HCMV on growth could affect the majority of the infant population. Moreover, growth effects at such an early age have been linked with lifetime risks of adult chronic disease and thus HCMV infection is a general public health concern [<xref ref-type="bibr" rid="bib17">17</xref>]. In the United States, children studied from age 6 years, showed reduced growth associated with increased infectious burden, including HCMV (30%–50% seropositive at outset). This resulted in health disparities that persisted to middle age [<xref ref-type="bibr" rid="bib18">18</xref>, <xref ref-type="bibr" rid="bib19">19</xref>].</p><p>HIV-unexposed infants with HCMV viremia at 6 months had higher length and head circumference <italic>z</italic> scores, whereas among maternally HIV-exposed infants, HCMV viremia was associated with lower <italic>z</italic> scores. This suggests that HIV-uninfected mothers, but not infected, provide some protective maternal immunity, permitting infants to tolerate HCMV infection. In the HIV-unexposed infants, HCMV may provide beneficial immune stimulation at this age, possibly contributing to the high HCMV seroprevalence in this population. There are similar examples with other sequential infections; for example, prior influenza infection affects outcome for subsequent respiratory syncytial virus infection [<xref ref-type="bibr" rid="bib20">20</xref>]. HCMV encodes a number of immunomodulatory proteins that favor virus persistence, but these proteins may also affect responses to other infections and host survival [<xref ref-type="bibr" rid="bib21">21</xref>–<xref ref-type="bibr" rid="bib23">23</xref>]. However, even if beneficial in the short term, long-term HCMV immune stimulation during infancy can be detrimental by driving early immune senescence [<xref ref-type="bibr" rid="bib24">24</xref>]. In West Africa, Malawi, and Gambia, HCMV-infected infants had expanded HCMV-specific T lymphocytes with markers of aged anergic cells, which have been previously identified in elderly European populations where HCMV is acquired later [<xref ref-type="bibr" rid="bib25">25</xref>, <xref ref-type="bibr" rid="bib26">26</xref>]. HCMV immune senescence may compromise the ability to respond to new infections during infancy in Africa, as suggested for the elderly in Europe [<xref ref-type="bibr" rid="bib24">24</xref>–<xref ref-type="bibr" rid="bib26">26</xref>]. Therefore, increased overall burden of all infections may affect healthy growth. This is supported by the 18-month HCMV antibody data, which shows that when overall HCMV infection is considered at times when maternal immunity wanes, there is a negative effect on growth.</p><p>HCMV may also directly affect growth and development, depending on the route of infection. HCMV frequently reactivates in HCMV IgG-positive mothers during lactation, and the virus is detectable in milk whey. Furthermore, HCMV is a pathogen of the gastrointestinal tract of HIV/AIDS patients and so may alter nutrient absorption, and can invade the central nervous system, possibly affecting development [<xref ref-type="bibr" rid="bib3">3</xref>, <xref ref-type="bibr" rid="bib4">4</xref>, <xref ref-type="bibr" rid="bib27">27</xref>, <xref ref-type="bibr" rid="bib28">28</xref>]. HCMV infection acquired in utero can cause neurological disease, while later postnatal infections, primarily via breast milk, are generally asymptomatic [<xref ref-type="bibr" rid="bib5">5</xref>]. In utero infection may account for HCMV effects on reduced head size and psychomotor development in HIV-exposed infants because adjustments for breastfeeding increased the effect. However, in separate analyses, we showed that the major route for infection in this cohort is via breastfeeding and that its duration over age 6 months is a risk factor, particularly for HIV-exposed infants. Studies in Europe of preterm births show symptomatic HCMV infection acquired via breast milk is associated with a growth disadvantage [<xref ref-type="bibr" rid="bib29">29</xref>, <xref ref-type="bibr" rid="bib30">30</xref>]. High HCMV load and prolonged excretion in breast milk are risk factors for acquisition [<xref ref-type="bibr" rid="bib27">27</xref>]; both factors were apparent for this HIV-exposed Zambian cohort.</p><p>Maternal HIV exposure increased some adverse effects of HCMV. Our previous analyses indicated that maternal HIV exposure led to a greater prevalence of high-load viremic infant HCMV infections [<xref ref-type="bibr" rid="bib10">10</xref>]. High-load HCMV viremia can correlate with symptomatic infection [<xref ref-type="bibr" rid="bib4">4</xref>, <xref ref-type="bibr" rid="bib31">31</xref>, <xref ref-type="bibr" rid="bib32">32</xref>]. Studies in Kenya of HIV-positive mother/child pairs showed that detection of maternal HCMV plasma DNA was associated with infant mortality [<xref ref-type="bibr" rid="bib33">33</xref>]. In our Zambian cohort, there was some evidence of increased hospitalization with HCMV viremia in the HIV-infected children, but this was not significant with maternal HIV exposure. Therefore, by affecting other diseases, the effects of HCMV on growth and development could be partially indirect; the effects appear to be a combination of direct and indirect causes. A limitation of our study was that the maternal CD4 count or HCMV status was not available and we could not determine the effects of HIV on maternal immunity or HCMV. Study strengths include analyses of HCMV effects in infants using both 6-month DNA for viremia and 18-month antibody for infection, with comparisons between maternally HIV-exposed and HIV-unexposed infants, controls for major confounding factors, and a large population-based study, the first in this region.</p><p>What may limit the effects of HCMV on infant growth and development in this region? Diagnostics for symptomatic congenital infections and their treatment with ganciclovir or its derivatives may be appropriate [<xref ref-type="bibr" rid="bib34">34</xref>, <xref ref-type="bibr" rid="bib35">35</xref>]. Recent evidence shows that high-avidity HCMV IgG can cross the placenta and contribute to viral replication control [<xref ref-type="bibr" rid="bib36">36</xref>]. This is an indication that hyperimmune globulin could also limit placental infection [<xref ref-type="bibr" rid="bib35">35</xref>], and so improving maternal immunity could limit infection. In France, ART of HIV-positive women decreased HCMV congenital infection [<xref ref-type="bibr" rid="bib37">37</xref>]. For HIV-positive mothers, limiting breastfeeding duration over 6 months could reduce infant HCMV infection; however, further study is required to assess the effects. In Zambia, HIV-positive women with advanced HIV/AIDS improved infant survival by decreasing breastfeeding, while those with less advanced HIV/AIDS improved survival of HIV-positive infants by increasing breastfeeding duration to longer than 4 months [<xref ref-type="bibr" rid="bib38">38</xref>, <xref ref-type="bibr" rid="bib39">39</xref>]. Because HCMV is frequently secreted in urine, improved hygiene could limit horizontal transmission. Preliminary analyses showed lower HCMV infant infection with the presence of private indoor toilets compared with outdoor toilets. Ultimately, HCMV vaccination could control new infections or reduce viremia in those already infected. Early trials of a subunit vaccine show promise [<xref ref-type="bibr" rid="bib40">40</xref>, <xref ref-type="bibr" rid="bib41">41</xref>].</p><p>In conclusion, HCMV infection in Zambia resulted in poor growth and development of maternally HIV-exposed infants and poor growth of HIV-unexposed children. Other African countries also have high HCMV childhood infection and endemic HIV. Therefore, efforts to improve child health will need to consider HCMV, particularly for effects on growth and development.</p></sec></body><back><ack><title>Notes</title><sec><title>Acknowledgments.</title><p>We thank all the mothers and children who participated in the study and are grateful for the support of Lusaka District Health staff who permitted the project.
