Cardiac Dysfunction Among Ugandan HIV-infected Children on Antiretroviral Therapy

Cardioprotective effects of early versus late initiated antiretroviral treatment in adolescents with perinatal HIV-1 infection

Whether, and how, cardioprotective effects of antiretroviral treatment (ART) in adolescents with perinatal HIV infection (APHIV) vary with age at treatment initiation is unknown. We used magnetic resonance imaging to compare cardiac status between APHIV initiated on ART at < 5 years of age (early ART, n = 37) and ≥ 5 years of age (delayed ART, n = 34) versus HIV-uninfected peers (n = 21), reporting z-score mean differences adjusted for confounders. Relative to HIV-uninfected adolescents, APHIV with early ART had higher left ventricular (LV) global circumferential strain (GCS) [adjusted mean (95%CI) z-score: 0.53 (0.13, 0.92)] and maximum indexed left atrium volume (LAVi) [adjusted z-score: 0.55 (0.08, 1.02)]. In contrast, APHIV with delayed ART had greater indexed LV end-diastolic volume (LVEDVi) [adjusted z-score: 0.47 (0.09, 0.86)] and extracellular volume fraction [adjusted z-score: 0.79 (0.20, 1.37)], but lower GCS [adjusted z-score: -0.51 (-0.91, -0.10)] than HIV-uninfected peers. APHIV had distinct albeit subclinical cardiac phenotypes depending on ART initiation age. Changes in early ART suggested comparatively worse diastology with preserved systolic function while delayed ART was associated with comparatively increased diffuse fibrosis and LV dilatation with reduced systolic function. The long-term clinical significance of these changes remains to be determined.

Cardioprotective effects of antiretroviral treatment in adolescents with perinatal HIV infection are heterogeneous depending on age at treatment initiation

The cardioprotective effects of antiretroviral treatment (ART) in adolescents with perinatal HIV infection (APHIV) may depend on age at ART initiation. We used cardiovascular magnetic resonance (CMR) to characterize and compare residual cardiac changes in apparently healthy APHIV with early and delayed ART initiation compared to sex- and age-similar HIV uninfected peers. We defined early and delayed ART as, respectively, treatment initiated at <5 years and ≥5 years of age. Cardiac function, mechanical deformation, geometry and tissue composition were assessed. APHIV had distinct albeit subclinical cardiac phenotypes depending on timing of ART initiation. For example, changes in early ART suggested comparatively worse diastology with preserved systolic function while delayed ART was associated with comparatively increased diffuse fibrosis and LV dilatation with reduced systolic function. The long-term clinical significance of these changes remains to be determined.

Antibody interventions in HIV: broadly neutralizing mAbs in children

PURPOSE OF REVIEW

Treatment strategies for children with HIV are evolving, with considerations beyond plasma viremic control that raise the possibility of reducing or eliminating latent reservoirs to achieve posttreatment control. Novel strategies that maintain HIV viral suppression and allow time off small molecule antiretroviral therapy (ART) are of high priority. Trials with broadly neutralizing mAbs (bNAbs) have begun in children and may become a viable alternative treatment option. Recent bNAb treatment studies in adults indicate that bNAbs may be associated with a reduction in viral reservoirs, providing optimism that these agents may provide a pathway towards posttreatment control that rarely occurs with small molecule ART.

RECENT FINDINGS

Children with HIV provide an ideal opportunity to study bNAbs as an alternative treatment strategy that reduces direct ART toxicities during critical periods of growth and development, allows time off ART and takes advantage of the distinct features of the developing immune system in children that could facilitate induction of more potent autologous cellular and humoral immune responses against HIV-1. To date, paediatric bNAb studies with reported results include IMPAACT P1112, IMPAACT 2008, IMPAACT P1115 and the Tatelo study, and these results will be reviewed.

SUMMARY

In this review, we summarize the current and planned paediatric bNAb studies, with an emphasis on trial results available to date. We highlight the potential benefits of immune-based therapies for the maintenance of viral suppression and its potential for achieving viral remission in children living with HIV.

Left ventricular hypertrophy in African children infected with HIV/AIDS: a case-control study

Introduction

left ventricular hypertrophy (LVH) measured by echocardiography seen in human immunodeficiency virus/acquired immunodeficiency disease (HIV/AIDS) affects the morbidity and mortality. The hemodynamic and metabolic changes in (HIV/AIDS) affect the heart adversely causing hypertrophic remodeling with left ventricular hypertrophy. The aim of this study was to determine the prevalence and risk factors associated with LVH in African children with HIV/AIDS.

Methods

an analytical case-control study was conducted using echocardiography to assess cardiac function. Descriptive statistics was used to determine percentages and univariate analysis to find association between dependent variable and independent variables. Independent variables that had an association in a univariate were included in the multivariate model to determine strength of association.

Results

the mean age of the study population was 7.8 ± 2.07 years for controls and 8.3 ± 3.04 years for cases respectively. They were made up of 51.2% (n= 86) males and 48.8% (n = 82) females (M: F=1.05: 1). We studied eighty-four (n= 84) cases, and LVH was seen in 67.7% (n= 56) of the patients. Mean left ventricular mass index (g/m2) was significantly higher in the cases (90.37± 35.50) than controls (89.37 ± 14.25, p= 0.04.) Relative wall thickness (mm) was within normal in the control, 0.35 ± 0.06 and high in the cases, 0.67 ± 0.17, p= 0.01. Eccentric hypertrophy was the most common type seen in 36.9% (n= 31) of the patients. Multiple linear regression analysis, revealed that the presence of LVH was associated with 0.212 (95% CI: 0.001 - 0.014; p= 0.001) lower Body mass index (BMI) for age and 0.396 (95% CI; 0.002 - 0.066; p= 0.03) lower CD4+ cell count as predictors of LVH.

Conclusion

the prevalence of LVH was high. Lower body mass index (BMI) and CD4+cells count predicted LVH. This supports the recommendation by the National Heart, Lung and Blood Institute (NHLBI) working group on research priorities for cardiovascular complications in HIV/AIDS, for baseline and periodic echocardiography in the management of children with HIV/AIDS.

Review of electrocardiographic abnormalities among people living with HIV in Sub-Saharan Africa: A systematic review

INTRODUCTION

Electrocardiographic (ECG) abnormalities are increasingly being reported among people living with HIV (PLWH). However, the exact prevalence of ECG abnormalities among PLWH in Sub-Saharan Africa (SSA), a region with one of the highest burdens of HIV, is not known. Through a systematic review, we determined the prevalence and patterns of ECG abnormalities among PLWH in SSA.

METHODS

We conducted a search in online databases including EMBASE, MEDLINE, CINAHL and Research for Life for studies published between 1st January 2000 and 31st December 2020. Studies reporting any form of ECG abnormalities published in English were screened and reviewed for eligibility. Retrieved studies were assessed for validity using the modified Newcastle-Ottawa Scale. Data was summarized qualitatively, and ECG abnormalities were further subcategorized into rate, conduction, and rhythm abnormalities as well as atrial and ventricular enlargements.

RESULTS

We retrieved seventeen of the 219 studies assessed for eligibility published between 2001 and 2020, with a total of 2,572 eligible participants. The mean age of the participants ranged between 6.8 years and 58.6 years. Of the 17 studies, 8 (47%) were case-control, 6 (35.3%) cross-sectional and 3 (17.6%) were cohort in design. Thirteen studies were conducted in the adult population while four were conducted in the pediatric population. The prevalence of ECG abnormalities ranged from 10% to 81% and 6.7% to 26.5% in the adult and pediatric population respectively. Among studies done in the adult population, conduction abnormalities were the most reported (9 studies) with a prevalence ranging from 3.4% to 53.5%. In the pediatric population, rate abnormalities were the most reported (4 studies) with a prevalence ranging from 3.9% to 20.9%. The heterogeneity in results could be attributed to the absence of uniform criteria to define ECG abnormalities.

CONCLUSION

Our findings highlight a high prevalence of ECG abnormalities among PLWH in SSA. Consideration of ECG in the comprehensive evaluation of cardiac dysfunction among PLWH in SSA maybe warranted.

Proinflammatory and cardiovascular biomarkers are associated with echocardiographic abnormalities in children with HIV taking antiretroviral therapy

OBJECTIVES

Children with perinatally acquired HIV (PHIV) and taking antiretroviral therapy (ART) have a high prevalence of subclinical cardiac disease. We hypothesized that cardiac disease may be a consequence of dysregulated systemic immune activation driven by HIV infection. We examined cardiovascular and proinflammatory biomarkers and their association with echocardiographic abnormalities in children with PHIV.

DESIGN

Cross-sectional analysis of soluble biomarkers from a prospective cohort of children aged 6-16 years with PHIV and age-matched HIV-uninfected comparison group.

METHODS

Cryopreserved plasma samples were used to measure seven soluble biomarkers using multiplex bead assay (Luminex). Multivariable logistic regression assessed how biomarker levels related to cardiac abnormalities.

RESULTS

A total of 406 children participated in this study (195 PHIV and 211 HIV-uninfected). Mean [standard deviation (SD)] ages of PHIV and HIV-uninfected participants were 10.7 (2.6) and 10.8 (2.8) years, respectively. Plasma levels of CRP, TNF-α, ST2, VCAM-1 and GDF-15 were significantly higher in the PHIV group compared with uninfected control ( P  < 0.001). Among children with PHIV, with one-unit representing one SD in biomarker level, a one-unit increase in CRP and GDF-15, was associated with increased odds of having left ventricular (LV) diastolic dysfunction [adjusted odds ratio (aOR), 1.49 (1.02-2.18; P  < 0.040)] and [aOR 1.71 (1.18-2.53; P  = 0.006)], respectively. Each one unit increase in GDF-15 was associated with increased odds of LV hypertrophy [aOR 1.84 (95% CI 1.10-3.10; P  < 0.021)].

CONCLUSION

Children with PHIV had higher levels of proinflammatory and cardiovascular biomarkers compared with HIV-uninfected children. Increased CRP and GDF-15 were associated with cardiac abnormalities in children with PHIV.

Pulmonary Hypertension in Children across Africa: The Silent Threat

Pulmonary hypertension (PH) is a complex puzzle in Africa, especially among children who present with a cocktail of issues including recurrent pulmonary infections, unoperated congenital heart disease, and advanced rheumatic heart disease. Sickle cell anemia and neonatal complications of transiting from fetal circulation also contribute to the burden of pulmonary hypertension. Mortality from pulmonary arterial hypertension (PAH) remains high in Africa (18-21%), claiming sufferers in the first 6 months after diagnosis. Unfortunately, PH remains underreported in sub-Saharan Africa since many centers lack the capacity to diagnose and confirm it by the recommended gold standard, right heart catheterization. The unresolved burden of unoperated congenital heart lesions and rheumatic heart disease, among other preventable causes, stand out as major causes of PH in African children. This paper highlights pediatric PAH as a result of major gaps in care and illustrates the need for its prevention as well as for the promotion of research into the most important drivers, to prevent premature mortality in the continent.

Cardiometabolic Complications in Youth With Perinatally Acquired HIV in the Era of Antiretroviral Therapy

PURPOSE OF REVIEW

Antiretroviral therapy (ART) scale-up has dramatically reduced rates of pediatric HIV mortality and morbidity. Children living with perinatally acquired HIV (PHIV) are now expected to live through adolescence and well into adulthood, such that adolescents now represent the largest growing population living with HIV. This review aims to discuss the prevalence and mechanisms for cardiometabolic comorbidities in the setting of newer ART regimens and the research gaps that remain.

RECENT FINDINGS

Data highlight the continued risks of subclinical cardiometabolic complications in PHIV in the setting of newer ART. Novel techniques in imaging and omics may help identify early cardiometabolic abnormalities in this young population and potentially identify early changes in the mechanistic pathways related to these changes. Further studies to determine risk and management strategies of the cardiometabolic effects in PHIV adolescents, beyond ART, are warranted. Focus should be on prevention of these complications in youth to avoid new epidemic of diabetes and cardiovascular disease when these youths become aging adults.

Craniofacial morphology of HIV-infected adolescents undergoing highly active antiretroviral therapy (HAART): An original research

OBJECTIVES:

To analyze the craniofacial morphology in child patients and adolescents by evaluating the skeletal cephalometric profile of the HIV infected patients in this age group and comparing them with the HIV-negative controls.

MATERIALS AND METHODS:

The present study was a planned case-control study which included 25 HIV-positive adolescent patients aged between 10 and 18 years (the study group) who were compared with 25 age- and sex-matched HIV-negative adolescent controls (the control group). All the patients had been HIV infected via a vertical transmission with positive serology confirmed in two different tests and had been kept on HAART since they were born. The diagnostic aids used for orthodontic documentation included facial photographs, digital orthopantomographs, lateral teleradiographs, and study models.

RESULTS:

With reference to the methodologies used for taking the cephalometric values, all the methods used were in strong agreement with each other for almost all the variables studied and had high intra-class correlation coefficient values except Co-A, SN.ANSPNS, and SNB which, too, had a good agreement of 60%. Nevertheless, the agreement was positive for these variables, too, since the P values obtained were found to be statistically significant (P < 0.05).

CONCLUSION:

Most of the measurements in the HIV-infected adolescents were found to be similar to the ones obtained for the HIV-negative controls, although, the study results highlighted the significance of further studies to be conducted in this regard, especially, the longitudinal study designs wherein the said variables can be studied on a follow-up basis in longitudinal studies to have an idea of the exact changes observed and their pattern in the included groups.

Chronic comorbidities in children and adolescents with perinatally acquired HIV infection in sub-Saharan Africa in the era of antiretroviral therapy

Globally, 1·7 million children are living with HIV, of which 90% are in sub-Saharan Africa. The remarkable scale-up of combination antiretroviral therapy has resulted in increasing numbers of children with HIV surviving to adolescence. Unfortunately, in sub-Saharan Africa, HIV diagnosis is often delayed with children starting antiretroviral therapy late in childhood. There have been increasing reports from low-income settings of children with HIV who have multisystem chronic comorbidities despite antiretroviral therapy. Many of these chronic conditions show clinical phenotypes distinct from those in adults with HIV, and result in disability and reduced quality of life. In this Review, we discuss the spectrum and pathogenesis of comorbidities in children with HIV in sub-Saharan Africa. Prompt diagnosis and treatment of perinatally acquired HIV infection is a priority. Additionally, there is a need for increased awareness of the burden of chronic comorbidities. Diagnostic and therapeutic strategies need to be collectively developed if children with HIV are to achieve their full potential.

Multisystem impairment in South African adolescents with Perinatally acquired HIV on antiretroviral therapy (ART)

INTRODUCTION

Adolescents with perinatally acquired HIV (PHIV) are at risk of chronic disease due to long-standing immune suppression, HIV disease and antiretroviral therapy (ART) exposure. However, there are few data on multisystem disease in this population. We investigated the overlapping burden of neurocognitive, cardiovascular, respiratory and/or renal impairment among PHIV positive (PHIV+) adolescents.

METHODS

In this cross-sectional analysis, participants aged 9 to 14 years on ART for >6 months were recruited from seven sites across Cape Town from July 2013 through March 2015, together with age-matched HIV-negative (HIV-) adolescents. Impairment at enrolment was assessed across neurocognitive functioning (using the youth-International HIV Dementia Scale); cardiac function (echocardiogram abnormality); respiratory function (abnormal spirometry) and renal function (abnormal glomerular filtration rate).

RESULTS AND DISCUSSION

Overall, 384 PHIV+ and 95 HIV- adolescents were included (mean age, 11.9 years; 49% female). Median age of ART initiation was 4.2 years (IQR: 1.7 to 7.6) and median CD4 count was 709 (IQR: 556 to 944) with 302 (79%) of PHIV+ adolescents virologically suppressed. Abacavir and Zidovudine were the most commonly used nucleoside reverse transcriptase inhibitors (NRTIs) with 60% of adolescents on non-nucleoside reverse transcriptase inhibitors (NNRTI) and 38% on a protease inhibitor (PI). Among PHIV+ adolescents, 167 (43.5%) had single system impairment only, 110 (28.6%) had two systems involved, and 39 (10.2%) had three or four systems involved. PHIV+ participants had more 2-system and 3-system impairment than HIV-, 110 (28.6%) versus 17 (17.9%), p = 0.03 and 39 (10.2%) versus 3 (4.3%), p = 0.03. PHIV+ participants who had failed a year of school (73.8% vs. 46.4%, p = 0.00) and with a viral load >1000 copies/mL at enrolment (16.8% vs. 8.1%, p = 0.03) were more likely to have dual or multisystem impairment. Of those with cardiac impairment, 86.7% had an additional system impaired. Similarly, in those with neurocognitive impairment, almost 60% had additional systems impaired and of those with respiratory impairment, 74% had additional systems impaired.

CONCLUSIONS

Despite relatively early ART initiation, there is a substantial burden of multisystem chronic impairment among PHIV+ adolescents. This phenomenon needs to be further explored as this population ages and begins to engage in adult lifestyle factors that may compound these impairments.

Cardiopulmonary dysfunction in perinatally HIV-infected South African adolescents on antiretroviral therapy: baseline findings from the Cape Town Adolescent Antiretroviral Cohort

INTRODUCTION

Antiretroviral therapy (ART) has reduced morbidity and mortality in sub-Saharan Africa, but the burden of coexistent cardiopulmonary disease in perinatally HIV-positive adolescents on antiretroviral therapy (ART) has not been well described. The aim of this study was to investigate the prevalence and associations of cardiopulmonary dysfunction in adolescents with perinatally acquired HIV on ART.

METHODS

For this cross-sectional analysis, 515 perinatally HIV-positive adolescents ages 9 to 14 years on ART for at least six months, and a comparator group of 110 age-matched HIV-uninfected adolescents were tested between August 2013 and April 2015 using echocardiography, six-minute walk test (6MWT) and spirometry. Those with either abnormal spirometry or abnormal 6MWT and any right or left systolic or diastolic dysfunction or abnormal mean pulmonary arterial pressure were considered as having impaired cardiopulmonary function. Logistic regression was used to investigate determinants of impaired cardiopulmonary function.

RESULTS

Overall, 474 adolescents with perinatally acquired HIV (mean [SD] age, 12 [1.6] years; median [IQR] ART duration, 7 [4.6 to 9.3] years; median [IQR] CD4 count, 712 [571 to 959] cell/mm3 ) and 109 HIV-uninfected adolescents mean (SD) age 11.8 (1.8) years, had successful cardiac and lung function testing. Impaired cardiopulmonary function was detected in 13% of adolescents with perinatally acquired HIV and 8% of HIV-uninfected adolescents, p = 0.136. Among adolescents with perinatally acquired HIV, those with low tricuspid annular plane systolic excursion (TAPSE) had significantly lower mean FEV1 , 1.5 L versus 1.6 L, p = 0.011. Height (OR 0.7, 95%CI 0.5 to 0.9), body mass index (OR 0.7, 95%CI 0.5 to 0.9) and past pulmonary tuberculosis (OR 2.3, 95%CI 1.2 to 4.4) were significantly associated with a low cardiopulmonary function.

CONCLUSIONS

Despite being on ART, cardiopulmonary dysfunction occurs in an appreciable proportion of perinatally HIV-infected adolescents but no significant difference to uninfected controls. This finding requires further exploration. Factors associated with dysfunction may be amenable to public health interventions to reduce cardiopulmonary disease in this population.

HIV and Cardiovascular Disease: Update on Clinical Events, Special Populations, and Novel Biomarkers

PURPOSE OF REVIEW

The objective of this review is to provide an update on the link between HIV infection and cardiovascular disease (CVD). We will focus our review mainly on literature describing clinical CVD events and understudied topics of importance.

RECENT FINDINGS

Heart failure, peripheral artery disease, and stroke are CVD modalities deserving more attention in the context of HIV infection in the highly active antiretroviral therapy era. Incidence data on clinical CVD from HIV populations in low- and middle-income countries are limited. Multisubstance use is common in HIV, but understudied as a moderator or mediator of the association between HIV and CVD. CVD risk assessment in HIV remains challenging, but new research into novel biomarkers may provide further insights. There is also a need for inclusion of non-biologic factors in our attempts to understand, quantify, and predict CVD risk among PLWHA. Significant attention has been paid to generating and testing hypotheses to understand the mechanisms of myocardial infarction in HIV. Similar attention is deserving for heart failure, PAD, stroke, and cardiovascular disease risk in resource-limited settings and among substance users with HIV.

Need for active cardiovascular screening in HIV-infected children under antiretroviral therapy in Africa

Unacceptably high incidence of pediatric HIV despite worldwide increased access to antiretroviral therapy. The routine management of these children includes provision of antiretroviral therapy, and periodic assessment of its results and complications. However, no systematic assessment of the nutritional status, lipid profile or screening for cardiovascular disease is done. Our study aimed at describing the occurrence of cardiovascular abnormalities in HIV-infected children under antiretroviral therapy, and at determining the vital outcomes 5 years after. A prospective observational study was implemented at a dedicated HIV center in Maputo City, where we gathered detailed socio-demographic data and performed full cardiovascular evaluation, including transthoracic cardiac ultrasound. A total of 47 children were examined (24 male) of which 10 had abnormal cardiac ultrasound: impaired systolic function (5 children); three had congenital heart defects; one had severe rheumatic aortic regurgitation and one had tuberculous pericarditis. Heart failure was present in five children. The study also uncovered the presence of malnutrition (36 patients; 80% had BMI below 18.5 kg/m2) and anemia in a considerable proportion of children. On 5 year follow up there was one death due to malária; three new cases of left ventricular dysfunction occurred among children who had normal ultrasound on recruitment. Our results support systematic cardiovascular risk profiling and disease screening in HIV-infected children on antiretroviral therapy, using cardiac ultrasound wherever possible.

High prevalence of echocardiographic abnormalities in older HIV-infected children taking antiretroviral therapy

Background:

Antiretroviral therapy (ART) has decreased mortality so that increasing numbers of children with HIV are reaching adolescence. However, longstanding HIV infection and/or its treatment in children is associated with noninfectious complications including cardiac disease. We investigated the prevalence, spectrum and risk factors for echocardiographic abnormalities among children established on ART.

Methods:

HIV-infected children aged 6–16 years, on ART at least 6 months were enrolled into a cross-sectional study from a public-sector paediatric HIV clinic in Harare, Zimbabwe. A standardized examination including transthoracic echocardiography was performed. Local echocardiographic reference ranges were used to define cardiac abnormalities. Logistic regression was used to examine the association between cardiac abnormalities and risk factors.

Results:

Of the 201participants recruited, 92 (46%) were girls and median age was 11 (IQR 9–12) years; CD4⁺ cell count was 727 cells/μl (IQR 473–935) and 154 (78%) had viral load less than 400 copies/ml. Echocardiographic abnormalities were found in 83 (42%); left ventricular (LV) diastolic dysfunction was the most common abnormality 45 (23%) and LV hypertrophy in 22 (11%). LV and left atrial dilatation were found in 9 (5%) and 16 (8%), respectively. Right ventricular dilatation and systolic dysfunction were found in 13 (7%) and 4 (2%), respectively, of whom 60% had concurrent left heart abnormalities. Current use of nevirapine was associated with LVH [aOR 3.14 (1.13–8.72; P = 0.03)] and hypertension was associated with LV diastolic dysfunction [aOR 3.12 (1.48–6.57; P < 0.01)].

Conclusion:

HIV-infected children established on ART have a high burden of echocardiographic abnormalities. Right heart disease was predominantly associated with left heart abnormalities and may be part of a global cardiomyopathic process. Further studies are needed to investigate the natural history, aetiology, and pathogenesis of these abnormalities, so that appropriate monitoring and treatment strategies can be developed.

Features of cardiovascular disease in low-income and middle-income countries in adults and children living with HIV

PURPOSE OF REVIEW

The current article addresses crucial issues in identifying risk of cardiovascular disease (CVD) in people living with HIV in low-income and middle-income countries (LMICs). These issues are in need of urgent attention to advance our knowledge and inform actions to mitigate CVD in this population. We address CVDs in adults living with HIV as well as the unique aspects pertaining to children living with HIV (CLHIV), a group sorely under-represented in this field.

RECENT FINDINGS

CVDs affecting adults such as hypertension, dyslipidemia, coronary artery disease, and heart failure, in addition to myocardial dysfunction, vascular diseases, and autoimmune phenomena are also being reported in CLHIV. In addition to the background disparity in prevalence of traditional CVD risk factors, it is also likely that differential access to antiretroviral treatment, the younger age of the HIV-infected population, and types of antiretroviral treatment commonly used in LMICs contribute to the observed differences.

SUMMARY

Overall, the state of evidence for CVD in LMICs is limited and at times contradictory. We summarize the evidence with suggestions for high priorities for further scientific investigation. Now is the crucial time to intervene in modifying CVD risk in LMICs.

Craniofacial morphology of HIV-positive children and adolescents undergoing antiretroviral therapy: A pilot study

INTRODUCTION

In this study, we aimed to analyze craniofacial morphology by assessing the skeletal cephalometric profiles of HIV-positive patients receiving antiretroviral therapy.

METHODS

For this study, 21 HIV-positive patients aged between 6 and 17 years (study group) were selected and compared with 21 normoreactive patients (control group), paired by sex and age. The patients were also divided into 3 age ranges (6-8, 9-12, and 13-17 years) considering the pubertal growth spurt as the central event. Eighteen (linear and angular) measurements were traced on teleradiographs by using 2 methodologies. The mean values of each measurement were compared between the study and control groups by age range.

RESULTS

The majority of the measurements checked in the HIV-positive children and adolescents for the 13-to-17 year age range were diminished, but not enough to generate a statistically significant difference in craniofacial growth. Statistically significant differences (P <0.05) were found only in the inclination of the palatal plane (6-8 years) and the position of the maxilla in the anteroposterior direction (13-17 years).

CONCLUSIONS

These results led us to conclude that some cephalometric measurements of HIV-positive children and adolescents may be similar to those of normoreactive subjects.
