Pulmonary Involvement in SARS-CoV-2 Infection Estimates Myocardial Injury Risk. Medicina (B Aires) 2022; 58:medicina58101436. [PMID: 36295594 PMCID: PMC9610985 DOI: 10.3390/medicina58101436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2022] [Revised: 10/06/2022] [Accepted: 10/08/2022] [Indexed: 11/21/2022] Open
Abstract
Background and Objectives: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection represents a pathology with primary pulmonary involvement and multisystemic impact, including cardiovascular injuries. The present study aimed to assess the value of clinical, biochemical, and imaging factors in COVID-19 patients in determining the severity of myocardial involvement, and to create a model that can be used toevaluate myocardial injury risk based on clinical, biochemical and imaging factors. Materials and Methods: We performed an observational cohort study on 150 consecutive patients, evaluating their age, sex, hospitalization period, peripheral oxygen saturation (SpO2) in ambient air, systolic and diastolic blood pressure, heart rate, respiratory rate, biochemical markers of cardiac dysfunction (TnI, and NT-proBNP), inflammatory markers (C reactive protein (CRP), fibrinogen, serum ferritin, interleukin-6 (IL-6), tumor necrosis factor alpha (TNFα)), D-dimers, lactate dehydrogenase (LDH), myoglobin and radio-imaging parameters. All patients underwent computerized tomography chest scan in the first two days following admission. Results: We observed elevated heart and respiratory rates, higher systolic blood pressure, and a lower diastolic blood pressure in the patients with cardiac injury; significant differences between groups were registered in TnI, NT-proBNP, LDH, CRP, and D-dimers. For the radiological parameters, we found proportional correlations with the myocardial injury for the severity of lung disease, number of pulmonary segments with alveolar consolidation, number of pulmonary lobes with pneumonia, crazy paving pattern, type of lung involvement, the extent of fibroatelectatic lesions and the mediastinal adenopathies. Conclusions: Myocardial injury occurred in 12% of patients in the study group. Ground glass opacities, interstitial interlobular septal thickening (crazy paving pattern), fibroatelectasic lesions and alveolar consolidations on CT scan were correlated with myocardial injury. Routine lung sectional imaging along with non-specific biomarkers (LDH, D-dimers, and CRP) can be further valuable in the characterization of the disease burden, thus impacting patient care.

Abstract
Objectives In 2020, according to the UNAIDS (Joint United Nations Programme on HIV/AIDS), more than 37 million people lived with human immunodeficiency virus (HIV) infection worldwide. The disease is known to affect several organs, and one of the most affected organs is the heart. Cardiac diseases are highly prevalent among HIV-infected individuals, and recent findings suggest that this could be due to the damage caused by the virus. HIV patients are subject to advanced immunosuppression, which may lead to cardiac muscle damage and, in turn, cardiomyopathy. We aimed to study the incidence of HIV-related cardiomyopathy. Methods A pilot cross-sectional study was conducted to assess cardiomyopathy among 200 HIV patients who presented to the Heart Center, Bushehr, Iran. Patients’ files were used to determine the demographic data including age, gender, education, marital status, history of illicit drug use, unsafe/unprotected sexual contact, and whether the patient was a prisoner. Several laboratory data were also collected from these files. Physical examination of the cardiovascular system and echocardiography were also included as part of the evaluation. Results Although at least four out of five patients presented with some kind of cardiac damage, including valvular damage and pericardial effusion, none was diagnosed with cardiomyopathy. Valvular dysfunction was detected in 88.5% of the patients. Diastolic dysfunction was found in 7.7% of them. The mean ejection fraction was found to be 58%. In addition to cardiomyopathy, none of the patients developed systolic dysfunction, wall motion abnormality, intra-cardiac mass, or vegetation. Conclusions Cardiovascular complications are common among HIV-infected patients. Cardiomyopathy was not detected in our patients. In addition, the most common manifestations that were detected among our patients were valvular heart diseases and pericardial effusion.

Abstract
Idiopathic inflammatory myopathies (IIMs) represent a heterogeneous group of disorders in which skeletal muscle is inappropriately targeted by the immune system. IIMs are characterized by inflammation of muscle and varying degrees of muscle dysfunction. Extra-muscular manifestations may involve heart, skin, joints, lungs, and gastrointestinal tract. Cardiovascular involvement is a feared event because is one of the leading causes of mortality in IIM patients. As the myocardium shares many features with the skeletal muscle, it is supposed that it can be affected by the same inflammatory processes, which take place during the different forms of IIMs. However, the full extent of this link and the mechanisms behind it are still not fully understood. Animal models have greatly improved our understanding of IIM pathomechanisms and have proven to be a useful tool for discovering therapeutic drug targets. Here we report the evidence of heart muscle involvement in different animal models of spontaneous IIMs, assuming a common autoimmune mechanism and presenting them as study models for human pathology.

Abstract
OBJECTIVES People living with HIV (PLWH) have increased risk of cardiovascular diseases compared with uninfected populations. We assessed structural cardiac abnormalities and their associated risk factors in well-treated PLWH and uninfected controls using multidetector computed tomography (MDCT). METHODS People living with HIV and age- and sex-matched uninfected controls underwent MDCT to determine left atrial volume (LAV), left ventricular diastolic volume (LVDV), right ventricular diastolic volume (RVDV) and left ventricular mass (LVM). All outcomes were indexed to body surface area (BSA) (LAVi, LVDVi, RVDVi and LVMi). RESULTS A total of 592 PLWH and 1184 uninfected controls were included in the study. PLWH had smaller mean (SD) LAVi [40 (8) vs. 41 (9) mL/m2 ; P = 0.002] and LVDVi [61 (13) vs. 65 (14) mL/m2 ; P < 0.001] but larger RVDVi [89 (18) vs. 86 (17) mL/m2 ; P < 0.001] than uninfected controls. HIV was independently associated with 7 mL (95% CI: -10 to -3) smaller LVDV, and with 12 mL (95% CI: 8-16) larger RVDV, and 4 g (95% CI: 1-6) larger LVM after adjustment for cardiovascular risk factors and BSA. Large RVDV in PLWH was not associated with obstructive lung function. CONCLUSIONS HIV was independently associated with smaller LVDV and larger RVDV and LVM. Alterations in cardiac chamber volumes in PLWH were mainly minor. The clinical impact of these findings is uncertain, but it seems unlikely that alterations in cardiac chamber volumes explain the increased burden of cardiovascular disease previously observed in PLWH.

Abstract
Background Human immunodeficiency virus (HIV) has been associated with an increased risk of coronary artery disease (CAD) in women. HIV-positive pre-menopausal women lose the cardio-protective effect of estrogen and are at a higher risk for developing CAD. Our study intended to assess the cardiovascular risk in HIV-positive pre-menopausal women. Methods This is a cross-sectional study using National Health and Nutrition Examination Survey (NHANES) datasets. The 10-year Framingham risk score for developing CAD was calculated for HIV-positive and HIV-negative women. The individual risk factors contributing to CAD were compared. The populations’ intent to reduce their risk and their doctor’s advice to reduce the risk were analyzed. A P-value < 0.05 was considered significant. Results Out of the available sample of 82,091 people, 9,635 women (11.7%) met the inclusion criteria of the study. Among them, 25 women were HIV-seropositive (0.25%). Though there was no significant difference in blood pressure, hemoglobin A1c, C-reactive protein, high-density lipoprotein or total cholesterol (P > 0.05), the mean Framingham risk score in pre-menopausal HIV-positive women (mean (M) = 2.12, standard deviation (SD) = 2.73) was significantly higher than the HIV-negative women (M = 0.95, SD = 1.94) (P < 0.01). Neither did majority of the HIV-positive women intend to decrease their cardiovascular risk nor did their healthcare providers advise them to do so. Conclusions The risk of developing CAD in pre-menopausal women is higher from traditional risk factors itself. While HIV is now proven to be an independent risk factor for developing CAD in women, focus should be on reducing the risk from traditional methods.

Abstract
Although the extensive rollout of antiretroviral (ARV) therapy resulted in a longer life expectancy for people living with human immunodeficiency virus (PLHIV), such individuals display a relatively increased occurrence of cardiovascular diseases (CVD). This health challenge stimulated significant research interests in the field, leading to an improved understanding of both lifestyle-related risk factors and the underlying mechanisms of CVD onset in PLHIV. However, despite such progress, the precise role of various risk factors and mechanisms underlying the development of HIV-mediated CVD still remains relatively poorly understood. Therefore, we review CVD onset in PLHIV and focus on 1) the spectrum of cardiovascular complications that typically manifest in such persons and 2) underlying mechanisms that are implicated in this process. Here, the contributions of such factors and modulators and underlying mechanisms are considered in a holistic and integrative manner to generate a unifying hypothesis that includes identification of the core pathways mediating CVD onset. The review focuses on the sub-Saharan African context, as there are relatively high numbers of PLHIV residing within this region, indicating that the greater CVD risk will increasingly threaten the well-being and health of its citizens. It is our opinion that such an approach helps point the way for future research efforts to improve treatment strategies and/or lifestyle-related modifications for PLHIV.

Abstract
BACKGROUND Involvement of right-sided heart chambers (RSHCs) in patients infected with human immunodeficiency virus (HIV) is common and is usually attributed to pulmonary arterial or venous hypertension (PH). However, myocardial involvement in patients with HIV is also common and might affect RSHCs even in the absence of overt PH. Our aim was to define morphologic and functional alterations in RSHC in patients with HIV and without PH. METHODS AND RESULTS A total of 50 asymptomatic patients with HIV and 25 control subjects without clinical or echocardiographic signs for PH were included in the study. Transthoracic echocardiography was used to obtain measurements. Patients with HIV had significantly increased right ventricular end-diastolic diameter (RVEDD) and right ventricular free wall thickness (RVFWT), as well as increased right atrial area and pulmonary arterial diameter, compared with control subjects. After adjustment for age, sex, and body surface area, RVFWT (average 1.81 mm, 95% confidence interval [CI] 0.35-3.26 mm) and RVEDD (average 6.82 mm, 95% CI 2.40-11.24 mm) were significantly higher in subjects infected with HIV. More patients with right ventricular hypertrophy were on antiretroviral treatment, and RVFWT was on average 1.3 mm higher (95% CI 0.24-2.37 mm) in patients on antiretroviral treatment after adjustment for confounders. CONCLUSIONS These findings suggest that alterations in RSHCs were present in patients with HIV without PH.

Abstract
Objective: Human immunodeficiency virus (HIV) infection may also be associated with cardiac dysfunction, thus negatively affecting patients’ morbidity and mortality. This preliminary study aimed at evaluating whether bi-and three-dimensional (3D) strain echocardiographic facilities were able to identify alterations in the right ventricular (RV) function in highly selected – because free from cardiovascular risk factors and other comorbidities – HIV patients. Materials and Methods: Eight of these specific HIV patients (age: 32.0 ± 3.6 years; 7 months) treated with highly active antiretroviral therapy (HAART) were enrolled and compared with 8 sex-, age-, and cardiovascular risk profile-matched healthy individuals. All underwent clinical evaluation and transthoracic echocardiography coupled with tissue Doppler, two-dimensional (2D), and 3D speckle tracking imaging to examine their RV function. Results: All standard echocardiographic parameters resulted in the normal range, with no significant differences between HIV and controls. On the contrary, 2D longitudinal strain (16.1% ±1.6% vs. 17.8% ±0.9%, P = 0.02) and Global 3D strain (28.5% ±3.6% vs. 33.5% ±1.9%, P = 0.0002) were reduced in the HIV group. Moreover, Global 3D strain values showed a direct correlation with RV fractional area change values (r = 0.66, P = 0.005). Conclusions: 2D longitudinal and 3D Global strain can identify an early asymptomatic RV impairment in HIV patients free from other risk factors and comorbidities. These findings seem to imply that also in treated with HAART and well-controlled HIV patients an early asymptomatic systolic RV dysfunction is present, as a distinctive and separated pathological entity compared with classic HIV-related pulmonary arterial hypertension and left ventricular dysfunction. In these patients, RV dysfunction is not revealed by standard echocardiography.

Abstract
While mortality rates related to cardiovascular disease (CVD) have decreased over time among adults with HIV, excess risk of CVD in the HIV-infected population may persist despite highly active antiretroviral therapy (HAART) treatment and aggressive CVD risk factor control. Beyond atherosclerotic CVD, recent studies suggest that HIV infection may be associated with left ventricular systolic and diastolic function, interstitial myocardial fibrosis, and increased cardiac fat infiltration. Thus, with the increasing average age of the HIV-infected population, heart failure and arrhythmic disorders may soon rival coronary artery disease as the most prevalent forms of CVD. Finally, the question of whether HIV infection should be considered in clinical risk stratification has never been resolved, and this question has assumed new importance with recent changes to lipid treatment guidelines for prevention of CVD.

Abstract
Background: Increasing rates of HIV have been observed in women, African Americans, and Hispanics, particularly those residing in rural areas of the United States. Although cardiovascular (CV) complications in patients infected with human immunodeficiency virus (HIV) have significantly decreased following the introduction of antiretroviral therapy on a global scale, in many rural areas, residents face geographic, social, and cultural barriers that result in decreased access to care. Despite the advancements to combat the disease, many patients in these medically underserved areas are not linked to care, and fewer than half achieve viral suppression. Methods: Databases were systematically searched for peer-reviewed publications reporting infectious and non-infectious etiologies of cardiovascular disease in HIV-infected patients. Relevant articles cited in the retrieved publications were also reviewed for inclusion. Results: A variety of outcomes studies and literature reviews were included in the analysis. Relevant literature discussed the manifestations, diagnosis, treatment, and outcomes of infectious and non-infectious etiologies of cardiovascular disease in HIV-infected patients. Conclusion: In these medically underserved areas, it is vital that clinicians are knowledgeable in the manifestations, diagnosis, and treatment of CV complications in patients with untreated HIV. This review summarizes the epidemiology and causes of CV complications associated with untreated HIV and provide recommendations for management of these complications.

Abstract
Viral infections have been implicated as the cause of cardiomyopathy in several mammalian species. This study describes hypertrophic cardiomyopathy (HCM) and myocarditis associated with feline immunodeficiency virus (FIV) infection in five cats aged between 1 and 4 years. Clinical manifestations included dyspnoea in four animals, one of which also exhibited restlessness. One animal showed only lethargy, anorexia and vomiting. Necropsy examination revealed marked cardiomegaly, marked left ventricular hypertrophy and pallor of the myocardium and epicardium in all animals. Microscopical and immunohistochemical examination showed multifocal infiltration of the myocardium with T lymphocytes and fewer macrophages, neutrophils and plasma cells. An intense immunoreaction for FIV antigen in the cytoplasm and nucleus of lymphocytes and the cytoplasm of some macrophages was observed via immunohistochemistry (IHC). IHC did not reveal the presence of antigen from feline calicivirus, coronavirus, feline leukaemia virus, feline parvovirus, Chlamydia spp. or Toxoplasma gondii. The results demonstrate the occurrence of FIV infection in inflammatory cells in the myocardium of five cats with myocarditis and HCM.

Abstract
Background Dilated cardiomyopathy occurring in HIV-infected patients raises both diagnostic and therapeutic challenging problems. Indeed myocardial involvement in HIV infection has been variously attributed to several causes, including viral, toxic, nutritional and autoimmune, but no specific treatment capable to substantially improve patients’ prognosis has been recognized so far. Case Presentation Hereby we describe the case of an autoimmune myocarditis manifesting with heart failure in a3 9-year-old man with HIV infection. Left ventricular endomyocardial biopsy showed a lymphocytic myocarditis characterized by over-expression of HLA-DR and negative polymerase chain reaction for cardiotropic viruses. Steroid treatment was followed by recovery of cardiac dimension and function. Conclusion Presence of auto-reactive myocarditis should be considered in patients with HIV-associated dilated cardiomyopathy. Its recognition by endomyocardial biopsy followed by steroid administration may result in a complete resolution of cardiac disease.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) infection has evolved from a highly stigmatized disease with certain progression to acquired immunodeficiency syndrome (AIDS) to a chronic disease affecting over 1 million Americans. With the success of current anti-retroviral therapies, cardiovascular disease, including advanced heart failure (HF), will be a major cause of morbidity and mortality in this population. METHODS A survey concerning heart transplantation (HT) and left ventricular assist device (LVAD) implantation attitudes and outcomes in HIV-infected patients was distributed to 103 American and 9 Canadian HT centers via fax, e-mail or telephone. RESULTS Eighty-nine centers (79%) responded. Eighteen HTs were performed in HIV(+) patients with 1-, 2- and 5-year survival of 100%, 100% and 63%, respectively. Eighty-two centers (92%) have never performed HT in HIV(+) patients and 51 centers (57%) marked HIV(+) status as a contraindication. Rationales for contraindication included: (1) high-risk patients should be avoided given the scarcity of organ supply (59%); (2) immunosuppression required for HT may induce progression to AIDS (51%); and (3) drug interactions may worsen patients' clinical outcomes (49%). Thirty-five left ventricular assist device (LVAD) implantations in HIV(+) patients were reported. Sixty-eight centers (76%) have never implanted an LVAD in an HIV(+) patient and 21 centers (20%) marked HIV(+) status as a contraindication, of which 61% indicated concern for device-related infection. CONCLUSIONS Most centers either explicitly consider HIV(+) status as a contraindication for or have never treated HIV(+) patients with advanced HF therapy. Our findings suggest unequal access to care and underscore the need to educate cardiovascular health-care providers on progress made with HIV therapies.

Abstract
BACKGROUND HIV-infected individuals are at increased risk for pulmonary hypertension and cardiomyopathy, portending a poor prognosis. Right ventricular (RV) dysfunction is associated with worse outcomes in these conditions, yet its prevalence is poorly defined in HIV. We sought to determine the prevalence of RV dysfunction in an outpatient HIV cohort. METHODS Echocardiograms were evaluated from 104 HIV-infected adults. Measurements included estimated pulmonary arterial systolic pressure (PASP) and several measures of RV function, including tricuspid annular plane systolic excursion (TAPSE), RV longitudinal myocardial strain (RVLMS), RV fractional area change (RVFAC), and myocardial performance index (MPI). RESULTS Sixteen subjects (15%) had PASP >35 mm Hg, yet RV function did not differ significantly from those with normal estimated PASP. RV dysfunction defined by RVFAC <35% occurred in 11%. RVLMS had a median value of -27.3%, and individuals below the median had lower TAPSE but no differences in left ventricular ejection fraction (LVEF), PASP, or other measures. Dyspnea was associated with the lowest quintile of RVLMS (≥-21.05%). There were 6 subjects with LVEF <50%, and these individuals had lower TAPSE but no differences in PASP or other RV functional measures. CONCLUSIONS RV dysfunction was common as estimated PASP >35 mm Hg and LV dysfunction, but these findings did not cosegregate. RV dysfunction in HIV-infected individuals may be a separate entity from LV/global cardiomyopathy or pulmonary hypertension and deserves further study.

Abstract
Sepsis in patients with human immunodeficiency virus (HIV) may be associated with the appearance of cardiac dysfunction. This is a challenge, both when making the differential diagnosis and determining the proper treatment, as there are numerous risk factors: Myocarditis due to the HIV itself, the presence or absence of highly active antiretroviral therapy, toxic substances, and cardiomyopathy associated with sepsis. The diagnostic and therapeutic approach to an HIV positive patient with septic shock and cardiac dysfunction is described, as well as a brief review of the different causes of cardiomyopathy which may affect this group of patients is also presented.

Abstract
The last decade has witnessed major advances in our understanding of the epidemiology and pathophysiology of HIV-related cardiovascular disease in sub-Saharan Africa. In this review, we summarise these and discuss clinically relevant advances in diagnosis and treatment. In the Heart of Soweto Study, 10% of patients with newly diagnosed cardiovascular disease were HIV positive, and the most common HIV-related presentations were cardiomyopathy (38%), pericardial disease (13%) and pulmonary arterial hypertension (8%). HIV-related cardiomyopathy is more common with increased immunosuppression and HIV viraemia. With adequate antiretroviral therapy, the prevalence is low. Contributing factors such as malnutrition and genetic predisposition are under investigation. In other settings, pericardial disease is the most common presentation of HIV-related cardiovascular disease (over 40%), and over 90% of pericardial effusions are due to Mycobacterium tuberculosis (TB) pericarditis. HIV-associated TB pericarditis is associated with a greater prevalence of myopericarditis, a lower rate of progression to constriction, and markedly increased mortality. The role of steroids is currently under investigation in the form of a randomised controlled trial. HIV-associated pulmonary hypertension is significantly more common in sub-Saharan Africa than in developed countries, possibly as a result of interactions between HIV and other infectious agents, with very limited treatment options. It has recently been recognised that patients with HIV are at increased risk of sudden death. Infection with HIV is independently associated with QT prolongation, which is more marked with hepatitis C co-infection and associated with a 4.5-fold higher than expected rate of sudden death. The contribution of coronary disease to the overall burden of HIV-associated cardiovascular disease is still low in sub-Saharan Africa.

Abstract
AIMS Human immunodeficiency virus infection (HIV) has been associated with cardiac dysfunction that, if present, can negatively affect morbidity and mortality of HIV-infected patients. Unfortunately, many of the studies on this topic were performed before the highly active antiretroviral therapy (HAART) was established. Thus, we performed a comprehensive meta-analysis to critically appraise the incidence of cardiac dysfunction in HIV-infected pauci symptomatic patients. METHODS AND RESULTS Medline, Cochrane Library, and Biomed Central were systematically screened for studies reporting on systolic and/or diastolic dysfunctions in HIV pauci-symptomatic patients. Baseline treatment and cardiac imaging data were appraised and pooled with random effect methods computing summary. At pooled analysis, including a total of 2242 patients from 11 studies, an overall average incidence of traditional cardiovascular risk factors was observed, while a low rate of previous coronary artery disease was reported. Incidence of systolic and diastolic left ventricular dysfunction was 8.33% (95% CI: 2.20-14.25) and 43.38% (95% CI: 31.73-55.03), respectively. Diastolic dysfunction was graded as first [31.85% (95% CI: 24.85-43.73)], second [8.53% (95% CI: 2.12-14.93)], and third degree [3.02% (95% CI: 1.78-4.27)]. At multivariate analysis, a high sensitivity C-reactive protein level >5 mg/L, active tobacco smoking and previous history of myocardial infarction were predictors of left ventricular systolic dysfunction [odd ratio 1.70 (95% CI: 1.03-2.77); 1.57 (95% CI: 1.03-2.34); and 15.90 (95% CI: 1.94-329.00), respectively]. Hypertension (OR = 2.30; 95% CI: 1.20-4.50) and older age (OR = 2.50 per 10 years increase; 95% CI: 1.70-3.60) were predictors of left ventricular diastolic dysfunction (Figure 3). CONCLUSIONS Systolic and diastolic dysfunction represent a common finding in pauci symptomatic HIV-infected patients, regardless to HAART.

Abstract
OBJECTIVE To analyse the outcome of children with left ventricular dysfunction placed on Highly Active Antiretroviral Therapy. METHOD This study is a retrospective review of records of Human Immunodeficiency Virus-positive children with left ventricular dysfunction. Demographic data were collected. Left ventricular fractional shortening, CD4 percentage, viral load, and nutritional status were compared before and during antiretroviral therapy. RESULTS We reviewed the records of 34 Human Immunodeficiency Virus-positive children with left ventricular dysfunction. In all, 18 patients received antiretroviral therapy (group one) and 16 were antiretroviral therapy naive (group two). The median age of group one at initial visit was 94 months, with a male-to-female ratio of 1:1. Of those, 17 children showed improved left ventricular function on treatment, with an increase in fractional shortening (median: 17-33.5%; p less than 0.0001). There was no significant statistical difference between the groups regarding initial fractional shortening. In group one, the CD4 percentage improved (median: 12% to 30.5%; p less than 0.0001), with viral load suppression (median: 24,900 copies per millilitre to less than 25 copies per millilitre; p less than 0.0001). There was weight gain in group one (median z-score: -1.70 to -1.32; p equal to 0.0083). Proper statistical analysis in group two was not possible because of poor follow-up of patients. CONCLUSION The findings are in keeping with other reports that have shown improvement in left ventricular function in patients with Human Immunodeficiency Virus-associated cardiomyopathy treated with Highly Active Antiretroviral Therapy. Recovery of myocardial function is associated with improvement in immunological and nutritional statuses.

Abstract
OBJECTIVE The objective of this article was to compare the left ventricular (LV) systolic function of human immunodeficiency virus (HIV)-infected children with that of healthy controls, determine the prevalence of LV systolic dysfunction in HIV-infected children, and its association with age, stage of disease, and use of zidovudine. STUDY DESIGN This was a comparative cross-sectional descriptive study. SETTING A University Teaching Hospital in North-Central Nigeria in 2008. PATIENTS One hundred fifty HIV-infected children aged 6 weeks-14 years, and an equal number of age- and sex-matched apparently healthy controls. OUTCOME MEASURES Left ventricular internal dimensions in diastole and systole, LV fractional shortening (FS) and ejection fraction (EF). Left ventricular systolic dysfunction was considered present when FS was <28% or EF was <50%. RESULTS Mean LV internal dimensions in diastole was similar in subjects and controls (P= .26). Left ventricular internal dimensions in systole was significantly larger in subjects (2.7 cm, 95% confidence interval [CI] 2.6-2.8 cm) than controls (2.4 cm, 95% CI 2.3-2.5 cm) (P < .001). Mean FS of 27.8% (26.8-28.8%) in subjects was significantly reduced compared with 33.7% (33.1-34.3%) in controls (P < .001), as was EF 61.5% (60.7-62.3%) in subjects and 70.5% (69.7-71.3%) in controls (P < .001). Left ventricular systolic dysfunction was detected in 75 (50.0%, 95% CI 41.7-58.3%) subjects and 5 (3.3%, 95% CI 2.2-6.7) controls (P < .001). Subjects with left ventricular systolic dysfunction were significantly older than those without (P < .001) but did not differ significantly from them with respect to zidovudine therapy or stage of disease. CONCLUSIONS Left ventricular systolic dysfunction is significantly more frequent in HIV-infected children compared with controls. Left ventricular systolic function in HIV-infected children deteriorates with increasing age and should be serially evaluated in them.

Abstract
PURPOSE OF REVIEW Compared with vast literature on the clinical, imaging, and in-vivo microbiology aspects of HIV disease, there is less on biopsy pathology and even less on autopsy data. This review focuses on some current clinico-pathological issues, with indications of where there is less certainty than we would like. RECENT FINDINGS The most important change in causes of death in HIV disease, since the advent of highly active antiretroviral therapy (HAART), is the reduction of classical AIDS-defining opportunistic diseases, with the compensating increase in background comorbidities related to lifestyle, infections including the hepatitis viruses and HHV8, ageing, drug toxicity and immune reconstitution inflammatory syndrome phenomena. In low-income countries, HIV contributes significantly to maternal mortality. SUMMARY To understand HIV disease better and manage future patients better, we need more tissue clinico-pathological correlation, including quality biopsy and autopsy evaluations.

Abstract
OBJECTIVE Cardiovascular complications in patients with HIV infection include myocardial, endocardial, pericardial, and vascular diseases. The complications are caused by the HIV infection itself, opportunistic infections, HIV-related tumors, and the side effects of highly active antiretroviral therapy. The article reviews the CT and MRI findings suggestive of HIV-related cardiovascular diseases. CONCLUSION The cardiovascular complications of HIV infection frequently overlap, making the diagnosis difficult. CT and MRI are useful for the noninvasive evaluation of these complications.

Abstract
A wide variety of cardiac disease states can induce remodelling and lead to the functional consequence of heart failure. These complex disease states involve a plethora of parallel signal transduction events, which may be associated with tissue injury or tissue repair. Innate immunity is activated in hearts injured in different ways, evident as cytokine release from the heart, activation of toll-like receptors involved in recognizing danger, and activation of the transcription factor nuclear factor kappa B. Nuclear factor kappa B regulates gene programmes involved in inflammation as well as the resolution of inflammation. The impact of this is an enigma; while cytokines, toll-like receptors, and nuclear factor kappa B appear to elicit myocardial protection in studies of preconditioning, the literature strongly indicates a detrimental role for activation of innate immunity in studies of acute ischaemia–reperfusion injury. The impact of activation of cardiac innate immunity on the long-term outcome in in vivo models of hypertrophy and remodelling is less clear, with conflicting results as to whether it is beneficial or detrimental. More research using genetically engineered mice as tools, different models of evoking remodelling, and long-term follow-up is required for us to conclude whether activation of the innate immune system is good, bad, or unimportant in chronic injury models.

Abstract
BACKGROUND Although highly active antiretroviral therapy (HAART) has dramatically reduced the morbidity and mortality associated with HIV infection, a number of antiretroviral toxicities have been described, including myocardial toxicity resulting from the use of nucleotide and nucleoside reverse transcriptase inhibitors (NRTIs). Current treatment guidelines recommend the use of HAART regimens containing two NRTIs for initial therapy of HIV-1 positive individuals; however, potential cardiotoxicity resulting from treatment with multiple NRTIs has not been addressed. METHODOLOGY/PRINCIPAL FINDINGS We examined myocardial tissue from twelve CD8 lymphocyte-depleted adult rhesus macaques, including eight animals infected with simian immunodeficiency virus, four of which received combined antiretroviral therapy (CART) consisting of two NRTIs [(9-R-2-Phosphonomethoxypropyl Adenine) (PMPA) and (+/-)-beta-2',3'-dideoxy-5-fluoro-3'-thiacytidine (RCV)] for 28 days. Multifocal infiltrates of mononuclear inflammatory cells were present in the myocardium of all macaques that received CART, but not untreated SIV-positive animals or SIV-negative controls. Macrophages were the predominant inflammatory cells within lesions, as shown by immunoreactivity for the macrophage markers Iba1 and CD68. Heart specimens from monkeys that received CART had significantly lower virus burdens than untreated animals (p<0.05), but significantly greater quantities of TNF-α mRNA than either SIV-positive untreated animals or uninfected controls (p<0.05). Interferon-γ (IFN-γ), IL-1β and CXCL11 mRNA were upregulated in heart tissue from SIV-positive monkeys, independent of antiretroviral treatment, but CXCL9 mRNA was only upregulated in heart tissue from macaques that received CART. CONCLUSIONS/SIGNIFICANCE These results suggest that short-term treatment with multiple NRTIs may be associated with myocarditis, and demonstrate that the CD8-depleted SIV-positive rhesus monkey is a useful model for studying the cardiotoxic effects of combined antiretroviral therapy in the setting of immunodeficiency virus infection.
