Abstract
INTRODUCTION Sickle cell disease (SCD), an inherited hemoglobinopathy, affects primarily African Americans in the U.S.A. In addition, about 15% African Americans carry sickle cell trait (SCT). Despite the risk associated with blood transfusions, SCD patients have lower risk of acquiring HIV-1 infection. SCT individuals might also have some protection from HIV-1 infection. AREAS COVERED Here, we will review recent and previous studies with the focus on molecular mechanisms that might underlie and contribute to the protection of individuals with SCD and SCT from HIV-1 infection. As both of these conditions predispose to hemolysis, we will focus our discussion on the effects of systemic and intracellular iron on HIV-1 infection and progression. We will also review changes in iron metabolism and activation of innate antiviral responses in SCD and SCT and their effects on HIV-1 infection. EXPERT OPINION Previous studies, including ours, showed that SCD might protect from HIV-1 infection. This protection is likely due to the upregulation of complex protein network in response to hemolysis, hypoxia and interferon signaling. These findings are important not only for HIV-1 field but also for SCD cure efforts as antiviral state of SCD patients may adversely affect lentivirus-based gene therapy efforts.

Infect Dis Ther 2021; 11:265-275. [PMID: 34800268 PMCID: PMC8847480 DOI: 10.1007/s40121-021-00560-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2021] [Accepted: 10/25/2021] [Indexed: 11/27/2022] Open
Abstract
INTRODUCTION The purpose of the study was to assess hepcidin levels and iron metabolism in otherwise healthy human immunodeficiency virus-1 (HIV-1)-infected males and the influence of antiretroviral therapy on hepcidin production, as data in this group are scarce. METHODS A total of 89 HIV-1-infected males, 42 on effective antiretroviral therapy (ART)-group A, 47 treatment-naïve-group B, and 27 healthy controls-group C, were enrolled. Erythrocytes parameters, iron metabolism parameters, hepcidin, highly sensitive C-reactive protein (hsCRP), interleukin 6 (IL-6), and soluble transferrin receptor (sTfR) levels were assessed. Conditions related to inflammatory activity, systemic metabolic diseases and iron supplementation were exclusion criteria. Convenience sampling was used. RESULTS Median age in HIV-1 group was 33 years, and 27 years in the control group. Median CD4+ T-cell count was 724 cells/μl in group A, and 488 cells/μl in group B (p = 0.0000). Nadir CD4+ T-cell count was 397 cells/μl in group A and 475 cells/μl in group B (p = 0.0001). Median value of HIV-1 viral load (VL) in group B was 16 900 copies/mL. The hepcidin value was lower in group A than in groups B (p = 0.0008) or C (p = 0.0004), without differences between groups B and C. The hepcidin value correlated with ferritin in groups A (r2 = 0.16; p = 0.008) and B (r2 = 0.39; p = 0.000), but not in group C (r2 = 0.11; p = 0.09). In group A, the hepcidin value correlated with current CD4+ count (r = 0.48, p = 0.0012), but there was no correlation in group B. There were no correlations of hepcidin values with CD4+ T cell nadir in group A (p = 0.371) or in group B (p = 0.477); ART period (p = 0.614); VL in group B (p = 0.71). No abnormalities of iron metabolism, hsCRP, IL-6, or sTfR were noted. CONCLUSIONS Asymptomatic HIV-1 infection does not cause clinically important iron metabolism alterations or increased hepcidin production. Hepcidin values decrease on effective antiretroviral therapy.

Abstract
People living with HIV (PLWHIV) are at high risk of anemia due to inadequate iron intake, HIV and opportunistic infections, and inflammation, and as a side effect of antiretroviral therapy. Though iron supplementation can reduce iron deficiency anemia (IDA) in the general population, its role in anemia and in the health of PLWHIV is unclear due to concerns that iron supplementation may increase HIV replication and risk of opportunistic infections. We systematically reviewed the evidence on indicators of iron status, iron intake, and clinical outcomes among adults and children with HIV. The evidence suggests that anemia is associated with an increased risk of all-cause mortality and incident tuberculosis among HIV-infected individuals, regardless of anemia type, and the magnitude of the risk is greater with more severe anemia. High serum ferritin is associated with adverse clinical outcomes, although it is unclear if this is due to high iron or inflammation from disease progression. One large observational study found an increased risk of all-cause mortality among HIV-infected adults if they received iron supplementation. Published randomized controlled trials of iron supplementation among PLWHIV tend to have small sample sizes and have been inconclusive in terms of effectiveness and safety. Large randomized trials exploring approaches to safely and effectively provide iron supplementation to PLWHIV are warranted.

Abstract
BACKGROUND Although injection substance users and individuals co-infected with Human Immunodeficiency Virus-1 and Mycobacterium tuberculosis suffer marked hematologic derangements, the rates, levels, morphologic types and associated risk factors of anemia among Human immunodeficiency virus and Mycobacterium tuberculosis coinfected injection substance users has not been reported in Kenya. METHODS This cross-sectional study determined anemia rates, levels and morphologic types. Anemia was associated with clinical markers of disease- underweight, immunosuppression and viral load. Complete blood count, CD4 T-cell enumeration and viral load were determined via standard laboratory methods. RESULTS All injection substance users had higher rates of anaemia (HIV+TB+ ISUs, 79.3%; HIV-TB+ISUs, 70.0%; HIV+TB- ISUs, 56.6% and HIV-TB- ISUs, 56.2%) relative to non-ISUs (16.6%; P<0.05). A significant proportion of HIV+TB+ISUs (47.8%) developed severe anemia than other clinical groups. The commonest morphologic type of anemia in HIV+TB+ISUs was microcytic hypochromic (43.5%) followed by normocytic hypochromic (17.4%) relative to the other clinical groups. HIV+TB+ ISUs with CD4 T-cells <200/uL (OR: 2.94, 95% CI: 1.41-6.13, P=0.004) and CD4 Tcells of 200-349/uL (OR: 3.24, 95% CI: 1.66-6.31, P=0.001) associated with higher odds of developing anemia. CONCLUSION This study revealed that severe anemia and microcytic hypochromic anemia are the most common erythrocytic sequelae among Human Immunodeficiency Virus-1 and Mycobacterium tuberculosis co-infected ISUs. Those with CD4 T-cells < 350/uL are utmost expected to develop anemia.

Abstract
This review was written to update the review that we published in Nutrition Research in 2007 by examining studies published in the last 11 years which describe the effects of trace mineral deficiencies and micronutrient supplementation on HIV infection and its progression. In addition, we included studies that explore the interactions between Highly Active Anti-Retroviral Therapy (HAART) and micronutrient nutrition, focusing on the essential trace minerals. This review summarizes the results described in relevant articles that were identified by literature searches conducted using the OVID Medline database. Four of the nine essential trace minerals, specifically chromium, iron, selenium, and zinc, can influence HIV progression and/or its treatment. Notably, copper-containing filters may prevent transmission of the HIV virus via breastfeeding. However, there is a lack of good evidence to date that fluoride, iodine, manganese, or molybdenum influence HIV infection. Recent studies reveal that HAART can alter serum trace mineral and vitamin concentrations, but the effects vary based on the medications used. Although they have contributed useful new data, the sample sizes for most of these studies were too small to draw definitive conclusions for introducing changes in the management of HIV infection. Larger studies are needed to better understand and define the roles of trace mineral and vitamin deficiencies and micronutrient supplementation in the management and treatment of HIV-infected patients.

Abstract
Background Anemia is frequent during HIV infection and is predictive of mortality. Although cART has demonstrated to reduce its prevalence, several patients still experience unresolved anemia. We aimed to characterize iron homeostasis and inflammation in HIV-infected individuals with mild anemia in relation to cART. Methods In this retrospective cohort study, HIV-infected patients with mild
anemia, CD4+ cells > 200/mm3 at baseline, maintaining virological response for 12 months after cART starting were selected within the Standardized Management of Antiretroviral Therapy Cohort (MASTER) cohort. Several inflammation and immune activation markers and iron homeostasis indexes were measured in stored samples, obtained at cART initiation (T0) and 12 months later (T1). Patients were grouped on the basis of hemoglobin values at T1: group A (> 13 g/dl) and B (< 13 g/dl). Wilcoxon rank sum test was used to compare biomarker values. Pearson correlation coefficients were calculated for all variables. Results cART improved CD4+ and CD8+ cell counts and their ratio, but this effect was significant only in group A. Only these patients had mild iron deficiency at T0 and showed higher transferrin and lower percentage of transferrin saturation than patients of group B, but differences disappeared with cART. cART decreased inflammation in all patients, but group B had higher levels of all markers than group A, reaching statistical significance only for IL-8 values at T1 (16 vs 2.9 pg/ml; p = 0.017). Hepcidin and IL-6 levels did not show significant differences between groups. Hemoglobin levels both at T0 and T1 did not correlate with any marker. Conclusions Baseline mild anemia in HIV-infected patients cannot always be resolved with durable efficient cART, possibly due to residual inflammation or immune activation rather than unbalanced iron homeostasis. Further research is needed on cytokine profiling to understand the mechanisms that induce anemia in HIV with suppressive cART.

Abstract
HIV- and highly active antiretroviral therapy (HAART)-associated elevations in oxidative stress likely play a role in incomplete immune reconstitution, opportunistic infections and non-AIDS co-morbidities. We aimed to test the hypothesis that children living with HIV exhibit elevated markers of oxidative stress and reduced antioxidant profiles and that HAART-therapy will exacerbate these differences. HIV-positive HAART-naïve (n = 50) and HAART-treated (n = 50) and HIV-negative control (n = 50) participants, 3-15 years of age, were recruited from Black Lion Hospital in Ethiopia. Serum malondialdehyde (MDA) and bilirubin were higher and vitamin C and zinc were lower in HAART-naïve and HAART-treated compared with HIV-negative subjects and higher in HAART-treated compared with HAART-naïve subjects. Uric acid was higher in HAART-naïve compared with HAART-treated and HIV-negative subjects. Differences in MDA and several antioxidants were also observed across treatment regimens. Thus, children living with HIV exhibited systemic elevations in oxidative stress and reduction in antioxidants, which are exacerbated with HAART therapy.

Abstract
Iron is an essential metal for cell survival that is regulated by the peptide hormone hepcidin. However, its influence on certain diseases is directly related to iron metabolism or secondary to underlying diseases. Genetic alterations influence the serum hepcidin concentration, which can lead to an iron overload in tissues, as observed in haemochromatosis, in which serum hepcidin or defective hepcidin synthesis is observed. Another genetic imbalance of iron is iron-refractory anaemia, in which serum concentrations of hepcidin are increased, precluding the flow and efflux of extra- and intracellular iron. During the pathogenesis of certain diseases, the resulting oxidative stress, as well as the increase in inflammatory cytokines, influences the transcription of the HAMP gene to generate a secondary anaemia due to the increase in the serum concentration of hepcidin. To date, there is no available drug to inhibit or enhance hepcidin transcription, mostly due to the cytotoxicity described in the in vitro models. The proposed therapeutic targets are still in the early stages of clinical trials. Some candidates are promising, such as heparin derivatives and minihepcidins. This review describes the main pathways of systemic and genetic regulation of hepcidin, as well as its influence on the disorders related to iron metabolism.

Abstract
HIV is a pandemic disease, and many cellular and systemic factors are known to alter its infectivity and replication. Earlier studies had suggested that anemia is common in HIV-infected patients; however, higher iron was also observed in AIDS patients prior to the introduction of antiretroviral therapy (ART). Therefore, the relationship between iron and viral infection is not well delineated. To address this issue, we altered the levels of cellular iron in primary CD4(+) T cells and showed that higher iron is associated with increased HIV infection and replication. In addition, HIV infection alone leads to increased cellular iron, and several ART drugs increase cellular iron independent of HIV infection. Finally, HIV infection is associated with increased serum iron in HIV-positive patients regardless of treatment with ART. These results establish a relationship between iron and HIV infection and suggest that iron homeostasis may be a viable therapeutic target for HIV.
