RESUMO

Nearly half of the deaths among hospitalized human immuno deficiency virus-infected patients in the highly active antiretroviral therapy era have been attributed to liver disease. This may range from an asymptomatic mild increase of liver enzymes to cirrhosis and liver failure. Different works of literature elucidated both retroviral infection and the adverse effects of highly active antiretroviral therapy as a cause of hepatotoxicity. Individual adaptations to medications and environmental exposures, shaped by cultural norms and genetic predispositions, could potentially modulate the risk and progression of liver disease in this population. Therefore, this study aims to assess the predictors of severe hepatotoxicity in retroviral-infected adults receiving highly active antiretroviral therapy regimens within the Ilubabor Zone, Southwest Ethiopia. A facility-based cross-sectional study was conducted among adult retroviral-infected patients in five selected anti-retro virus therapy clinics from May1 to July 30/2022. A systematic sampling technique was used to select 457 study participants and Binary logistic regression statistical data analysis was used, P value < 0.05 was considered statistically significant. The prevalence of severe hepatotoxicity was 21.44% in the study population. CD+4 count < 200 cells/mm3 (AOR = 2.19, 95% CI 1.04-5.22, P = 0.01), human immunodeficiency virus co-infection with tuberculosis (AOR = 2.82, 95% CI 1.01-8.29, P = 0.03) and human immuno deficiency virus co-infection with hepatitis-B/hepatitis C virus (AOR = 5.02, 95% CI 1.82-16.41) were predictors of severe hepatotoxicity. The magnitude of severe hepatotoxicity was high among adult retroviral-infected patients on highly active anti-retroviral drug regimens. Co-infection of human immuno deficiency virus with hepatitis B virus or hepatitis C virus, tuberculosis and CD4+T-cell count below 200 cells/mm3 were predictors of severe hepatotoxicity. Therefore, HIV patients on highly active antiretroviral therapy require close attention and regular monitoring of their liver function.

RESUMO

Highly active antiretroviral therapy (ART) can effectively inhibit virus replication and restore immune function in most people living with human immunodeficiency virus (HIV). However, an important proportion of patients fail to achieve a satisfactory increase in CD4+ T cell counts. This state is called incomplete immune reconstitution or immunological nonresponse (INR). Patients with INR have an increased risk of clinical progression and higher rates of mortality. Despite widespread attention to INR, the precise mechanisms remain unclear. In this review, we will discuss the alterations in the quantity and quality of CD4+ T as well as multiple immunocytes, changes in soluble molecules and cytokines, and their relationship with INR, aimed to provide cellular and molecular insights into incomplete immune reconstitution.

RESUMO

OBJECTIVE: Previous research indicates an increased risk of cerebral aneurysm formation in adults living with human immunodeficiency virus (ALWH), however there are few longitudinal studies on the risk factors for and outcomes of cerebral aneurysms in this population. We aim to describe the characteristics and evolution of cerebral aneurysms in a large cohort of ALWH. MATERIALS AND METHODS: A chart review was completed for all adults evaluated at an urban, safety-net U.S. hospital between January 1, 2000, and October 22, 2021, with history of both HIV and at least one cerebral aneurysm. RESULTS: A total of 82 cerebral aneurysms were identified amongst 50 patients (52% female sex). Forty-six percent of patients with a nadir CD4 count less than 200 cells/mm3 (N=13) and 44% of patients with maximum viral load >10,000 copies/mL (N=18) developed new aneurysms or were found to have aneurysm growth over time compared with 29% of patients with a CD4 nadir above 200 cells/mm3 (N=21) and 22% of patients with maximum viral load

RESUMO

Antiretroviral therapy may alter susceptibility to nonkeratinocyte skin cancers (NKSCs) by improving immunity in people living with HIV. Using linked data from HIV and cancer registries in 12 states/regions in the United States during the antiretroviral therapy era (1996‒2018), we calculated standardized incidence ratios for 27 NKSCs, comparing incidence with that of the general population. Risk factors for NKSCs were evaluated using Poisson regression. There were 2,743 NKSCs diagnosed in 585,706 people living with HIV followed for 4,575,794 person-years. Kaposi sarcoma was the most common cancer (82%), followed by melanoma (12%) and cutaneous lymphoma (2.6%). Incidence was elevated for virus-related NKSCs: Kaposi sarcoma (standardized incidence ratio = 147, 95% confidence interval = 141‒153), diffuse large B-cell lymphoma (standardized incidence ratio = 5.19, 95% confidence interval = 3.13‒8.11), and Merkel cell carcinoma (standardized incidence ratio = 3.15, 95% confidence interval = 1.93‒4.87); elevated incidence for diffuse large B-cell lymphoma and Merkel cell carcinoma was observed only among people living with HIV with a previously acquired immunodeficiency syndrome diagnosis. Kaposi sarcoma risk was highest among men who have sex with men. Incidence was not increased for melanoma, adnexal carcinomas, and sarcomas. Melanoma and Merkel cell carcinoma arose disproportionately on sun-exposed skin, supporting a role for UVR in their development. In conclusion, risk for most NKSCs was similar to that of the general population during the antiretroviral therapy era, suggesting that people living with HIV without NKSC risk factors may not require intensive skin surveillance.

RESUMO

INTRODUCTION: Human immunodeficiency virus (HIV) positive patients are at high risk for osteonecrosis along with age-related osteoarthritis, resulting in a high number of joint reconstruction surgeries at younger ages in these immunosuppressed patients. Few previous studies have reported on patient outcomes in HAART (highly active antiretroviral therapy) compliant patients undergoing primary arthroplasty. The aim of this study is to report one institution's overall rate of complications and revision in HAART-compliant patients after primary hip and knee arthroplasty. METHODS: A retrospective chart review was performed spanning a 4 year period. This study included 50 primary joint arthroplasty patients diagnosed with HIV including 13 TKA (total knee arthroplasty) and 37 THA (total hip arthroplasty) with a prior diagnosis of HIV infection. Preoperative CD4 count and viral loads were recorded. Charts were reviewed for post-operative complications including infection and revision. RESULTS: The were a total of 11 postoperative complications (22%). There were 3 cases (6%) of soft tissue infection, 3 cases (6%) of implant loosening, 2 cases (4%) of dislocation, 1 case (2%) of lower extremity weakness, 1 case (2%) of venous thrombosis, and 1 case (2%) of arthrofibrosis. Of all patients, there were 6 cases of revision in this cohort (12%), 5 of which were aseptic etiology. All 3 infected patients had a history of IVDU. Two of these infected patients resolved with IV antibiotics while 1 underwent two-stage revision (2%). Patients that experienced post-operative complications had significantly elevated preoperative CD4 levels (983 versus 598, p = 0.003). CONCLUSION: Arthroplasty is a viable option for HAART-compliant patients. Most previous studies showing a higher risk for deep tissue infection and revision in HIV patients have not accounted for modern HAART. Our results show that compliance with HAART has vastly improved the outcomes of arthroplasty in these patients, while a history of IVDU is likely the largest risk factor for infection in this population.

RESUMO

Highly active anti-retroviral therapy (HAART) is currently the main stay in the treatment of Human Immunodeficiency Virus (HIV) disease. This treatment regimen typically combines three or more antiretroviral drugs and like most drug combinations or polypharmacy, has side effects including those on reproductive function which could place HIV patients on HAART under double risk in terms of reproductive function. Part of tissue damage following HAART administration is blamed on oxidative stress. We therefore sought to explore effects of Omega 3 and Selenium, two common antioxidants on HAART-induced male reproductive impairment in a non-HIV animal model. Sixteen male adult Wistar rats weighing 120g to 250g used for the study were grouped into 4 groups of four rats each (control, HAART-only, HAART + Omega 3 and HAART + Selenium groups). Duration of daily administration was six weeks. Results showed no significant changes in pH of epidydimal semen among the groups. Sperm count and viability were significantly reduced in HAART-only compared with control (p<0.05) but increased in HAART + Omega 3 and HAART + Selenium groups compared with HAART-only group (p< 0.05). Sperm motility was significantly reduced in HAART-only compared with control group (p< 0.05). A significantly higher percentage of total sperm defects was observed in HAART-only group compared with control (p <0.05) but significantly lower in the HAART + Selenium compared with HAART-only groups (p<0.05). Serum testosterone was significantly reduced in HAART-only compared with control groups (p<0.05) but significantly increased in HAART + Omega 3 and HAART + Selenium groups compared with HAART- only group (p<0.05). Serum concentration of luteinizing and follicle stimulating hormones were not significantly different among the groups. Testicular concentration of malondialdehyde was significantly increased in HAART-only compared with control (p<0.05) but significantly reduced in HAART + Omega 3 and HAART + Selenium groups compared with HAART-only group (p<0.05 in each). Testicular glutathione peroxidase activity was significantly reduced in HAART-only and HAART + Selenium groups compared with control (p< 0.05), but significantly higher in HAART + Omega 3 and HAART + Selenium compared with HAART-only groups (p<0.05 each). Testicular superoxide dismutase activity was significantly lower in the HAART-only and HAART + Selenium compared with control (p<0.05) but significantly higher in HAART + Omega 3 and HAART + Selenium compared with HAART-only groups (p<0.05 each). Level of tumour necrosis factor - alpha in testes was significantly higher in HAART-only (p<0.05) but lower in the HAART + Selenium (p<0.05) groups compared with control. Tumor necrosis factor-alpha was however significantly reduced in HAART + Omega 3 and HAART + Selenium groups compared with HAART-only (p<0.05 each) groups. Interleukin-6 levels were significantly increased in all HAART-administered groups compared with control (p<0.05 each) though significantly reduced in HAART + Omega 3 and HAART + Selenium compared with HAART-only groups (p<0.05 each). In conclusion, co-administration of Omega 3 or Selenium with HAART ameliorates HAART-induced male reproductive impairment, alteration in redox and inflammatory status in rats. Keywords: HAART, male reproductive impairment, Omega 3, Selenium.

RESUMO

ABSTRACT: Kaposi sarcoma is a tumor caused by Kaposi sarcoma herpesvirus, also known as human herpesvirus 8. Its occurrence is associated with an immunocompromised state. Kaposi sarcoma that occurs among people living with HIV (PLWH) is known as epidemic Kaposi sarcoma. Despite the decline in HIV-associated complications because of the introduction of combination antiretroviral therapy two decades ago, Kaposi sarcoma continues to affect PLWH worldwide. It affects young African American men more than other age and racial groups and can result in multiorgan dysfunction, leading to short-term and chronic debilitating symptoms as well as death. While some patients with epidemic Kaposi sarcoma are managed as outpatients, others may require higher levels of care and their acuity may fluctuate throughout their life span. Therefore, nurses, regardless of their specialty, may experience caring for a patient with epidemic Kaposi sarcoma at some point in their career. Learning about this condition and the needs of patients who have it will help nurses provide effective care. Here, the authors describe Kaposi sarcoma in general as well as the epidemiology, characteristics, and management of epidemic Kaposi sarcoma. They also describe specific nursing considerations in the care of PLWH who have the disease.

RESUMO

Highly active antiretroviral therapy (HAART) comprises a combination of two or three antiretroviral (ARV) drugs that are administered together in a single tablet. These drugs target different steps within the human immunodeficiency virus (HIV) life cycle, providing either a synergistic or additive antiviral effect; this enhances the efficiency in which viral replication is suppressed. HIV cannot be completely eliminated, making HAART a lifetime treatment. With long-term HAART usage, an increasing number of patients experience a broadening array of complications, and this significantly affects their quality of life, despite cautious use. The mechanism through which ARV drugs induce toxicity is associated with metabolic complications such as mitochondrial dysfunction, oxidative stress, and inflammation. To address this, it is necessary to improve ARV drug formulation without compromising its efficacy; alternatively, safe supplementary medicine may be a suitable solution. The medicinal plant Moringa oleifera (MO) is considered one of the most important sources of novel nutritionally and pharmacologically active compounds that have been shown to prevent and treat various diseases. MO leaves are rich in polyphenols, vitamins, minerals, and tannins; studies have confirmed the therapeutic properties of MO. MO leaves provide powerful antioxidants, scavenge free radicals, promote carbohydrate metabolism, and repair DNA. MO also induces anti-inflammatory, hepatoprotective, anti-proliferative, and anti-mutagenic effects. Therefore, MO can be a source of affordable and safe supplement therapy for HAART-induced toxicity. This review highlights the potential of MO leaves to protect against HAART-induced toxicity in HIV patients.

RESUMO

BACKGROUND: Cachexia is usually associated with elevated serum interleukin-6 (IL.6) as it stimulates the breakdown of muscle proteins and promotes wasting. OBJECTIVE: A case-control study to evaluate the relationship between weight loss, facial fat loss, and IL-6 in antiretroviral-naïve and treated participants living with HIV/AIDS. METHODS: IL-6 was assayed by High performance liquid chromatography (HPLC) in 97 in consecutive newly diagnosed antiretroviral-naive (ART-naïve) people living with HIV/AIDS (age ≥18 years); and 118 consecutive, age-matched participants currently on Highly Active Antiretroviral Therapy (HAART), using age as a criterion. In the treated group, 78 (66.7%) subjects were on zidovudine, lamivudine with nevirapine (Z+L+N); 27(23.1%) on tenofovir, lamivudine with emtricitabine (T+L+E); 5(4.3%) on zidovudine, lamivudine with emtricitabine (Z+L+E); 4(3.4%) on zidovudine, lamivudine with tenofovir (Z+L+T); 2(1.7%) on lamivudine, tenofovir with nevirapine (L+T+N); 1(0.9%) on tenofovir, zidovudine, emtricitabine (Z+T+E). RESULTS: A total of 215 participants: 97 ART-naive and 118 HAART-treated, age-matched subjects (40.3±9.6 versus 42.7±10.20years, p=0.08). The mean IL-6 was significantly higher in naïve than treated (0.69±0.04 versus 0.66±0.04 pg/ml, p =0.002). In all, 73 subjects experienced weight loss, 56(76.7%) naive, 17(23.3%) treated, p <0.0001, with significantly higher IL-6 in those with weight loss (0.69±0.05 versus 0.67±0.05pg/ml, p= 0.047). Fifty-eight (27.0%) subjects experienced facial fat loss, 49 (84.5%) naïve, and 9 (15.5%) treated, p <0.0001, with significantly higher IL-6 in those with facial fat loss (0.7 ± 0.05 versus 0.67±0.05pg/ml, p= 0.0001). Negative correlation exists between IL-6 and CD4+ count (r=-0.141, p=0.041). In logistic regression, independent predictors of weight loss include: IL-6 (Adjusted Odds Ratio, aOR 1.3, 95%CI 0·1-2·6, p=0.047); HIV duration (aOR 11.6, p <0.0001); AIDS-defining illness (aOR 3.5, p <0.0001); CD4+ count (aOR 3.2, p=0.004); HAART status (aOR 2.7, p<0.0001). CONCLUSION: HIV infection is associated with elevation of serum interleukin-6, which likely contributes to weight and facial fat loss among the treatment-naïve participants; while HAART is associated with suppressed IL-6 levels, thereby ameliorating weight and facial fat loss. Inverse relationship exists between serum IL-6 and CD4+ count; serum IL-6 could differentiate between mild- to moderate and severe immunosuppressive states.

RESUMO

OBJECTIVE: To compare the HIV-related ocular manifestations between HAART-naïve (Highly active antiretroviral therapy) and HAART-treated patients. STUDY DESIGN: Observational (comparative) Study. Place and Duration of the Study: Department of Ophthalmology and Family Care Centre of Hayatabad Medical Complex, Peshawar, Pakistan, from October 2019 to July 2021. METHODOLOGY: HIV-infected patients, who were receiving HAART treatment as well as HAART-naïve, were recruited. A complete ocular examination was performed to check for HIV-related ocular manifestations. Anterior and posterior segment findings were recorded and compared between the two groups. RESULTS: Of the 80 participants (40 in each group), 62 (77.5%) were males and 18 (22.5) were females with no significant difference between the groups for either gender (p=1.0). A significant difference, between the two groups, was found in the mean duration (838.64 + 908.16 days) of HIV infection at the time of recruitment (p<0.001). HIV-related ocular manifestations were found in 6 (7.5%) with no statistically significant difference between the two groups (p=1.0). Similarly, the involvement of systemic co-infections was found in 6 (7.5%) with no statistically significant difference between the groups (p=0.675). CONCLUSION: There was no difference in both groups when analysed for HIV-related ocular manifestations or systemic co-infections. The authors' finding contradict with some of the previously published data. Therefore, it is recommended that further research should be carried out to reach definite conclusion. KEY WORDS: HIV, Eye manifestations, Acquired immunodeficiency syndrome, Highly active antiretroviral therapy, HIV-related opportunistic infections, Pakistan.

RESUMO

The human immunodeficiency virus (HIV) is one of the most prevalent diseases globally. It is estimated that 37.7 million people are infected with HIV globally, and 8.2 million persons are infected with the virus in South Africa. The highly active antiretroviral therapy (HAART) involves combining various types of antiretroviral drugs that are dependent on the infected person's viral load. HAART helps regulate the viral load and prevents its associated symptoms from progressing into acquired immune deficiency syndrome (AIDS). Despite its success in prolonging HIV-infected patients' lifespans, the use of HAART promotes metabolic syndrome (MetS) through an inflammatory pathway, excess production of reactive oxygen species (ROS), and mitochondrial dysfunction. Interestingly, Spirulina platensis (SP), a blue-green microalgae commonly used as a traditional food by Mexican and African people, has been demonstrated to mitigate MetS by regulating oxidative and inflammatory pathways. SP is also a potent antioxidant that has been shown to exhibit immunological, anticancer, anti-inflammatory, anti-aging, antidiabetic, antibacterial, and antiviral properties. This review is aimed at highlighting the biochemical mechanism of SP with a focus on studies linking SP to the inhibition of HIV, inflammation, and oxidative stress. Further, we propose SP as a potential supplement for HIV-infected persons on lifelong HAART.

RESUMO

BACKGROUND: Though the initiation of Highly Active Antiretroviral Therapy (HAART) has led to decreased HIV/AIDS related mortality, the regimen has been reported to be associated with lipid toxicities. Baseline data on such disturbances are required to induce countrywide interventional HIV/AIDS programs. The aim of this study was to determine the frequency and risks of dyslipidemia in HIV patients on HAART medication in Eritrea. METHODS: A cross sectional study was conducted on HIV/AIDS patients in two national referral hospitals in Asmara, Eritrea. A structured questionnaire was used to collect demographic data and blood sample was taken for analyses of lipid profile tests. Data was analyzed using chi-square test, Post Hoc and logistic regression in SPSS software. RESULTS: The study included 382 participants of whom 256(67%) were females. Their median age, CD4+ T cell count (cell/microliter) and duration of HAART (years) was 45(IQR: 38-51), 434(IQR: 294-583) & 5(IQR: 3-5) respectively. The prevalence of dyslipidemia was 331(86.6%). Increased Low Density Lipoprotein-C (LDL-C) 213(55.8%) was the predominant abnormality. Abacavir was significantly related with highest means of triglycerides (TG) (228.17 ± 193.81) and lowest means of High Density Lipoprotein (HDL-C) (46.94 ± 12.02). Females had substantially higher proportions of TG (aOR = 2.89, 95% CI: 1.65-5.05) and TC/HDL ratio (aOR = 2.33, 95% CI: 1.40-3.87) and low HDL-C (aOR = 2.16, 95% CI: 1.34-3.48). Increased age was related with increased pro-atherogenic lipid parameters. High LDL-C was more infrequent in non-smokers (aOR = 0.028, 95% CI: 0.12-0.69). CONCLUSION: The study showed a high prevalence of dyslipidemia in HIV-patients receiving HAART in Eritrea. Sex, age and smoking practice were among key factors associated with dyslipidemia. The necessity to assess lipid profiles and other cardiovascular risk factors before initiation of HAART treatment and continuous monitoring during therapy is mandatory.

RESUMO

Cancers are the leading cause of death among people living with HIV/AIDS (PLWHA); however, nationwide studies on cancer incidence are limited. We aimed to determine the trends in the incidence rates of AIDS-defining cancers (ADCs) and non-AIDS-defining cancers (NADCs) among Korean PLWHA. Data from the National Health Insurance Sharing Service from 2004 to 2017 were collected. Age- and sex-adjusted standardized incidence ratios (SIRs) for various cancer types relative to the general population were calculated. Of the 11,737 PLWHA followed-up for 65,052 person-years (PYs), 445 (ADCs, 130 and NADCs, 298) developed cancer. The incidence rate of ADCs decreased, whereas that of NADCs remained unchanged. PLWHA were at an increased risk of ADCs (SIR: 12.6, 95% CI: 10.6-15.0), including Kaposi's sarcoma, non-Hodgkin's lymphoma, and cervical cancer, and some NADCs, including anal cancer, lung cancer, liver cancer, and oropharyngeal cancer. Of the 396 patients who received antiretroviral therapy (ART), 215 with optimal adherence had lower incidence rates for ADCs and NADCs than those with non-optimal adherence. The 5-year survival rate of PLWHA with NADCs was 57.8%. Close surveillance and routine screening of cancers and improvement in ART adherence are required to improve the clinical outcomes of PLWHA.

RESUMO

BACKGROUND: Lipodystrophy associated with the human immunodeficiency virus (HIV) is an unpleasant disorder found in 6%-80% of patients infected with HIV. Brazil has a universal public health system, an effective program for patients diagnosed with HIV, providing lipodystrophy treatment since 2004. The objective of this article is to describe the Brazilian approach to this complication. METHOD: A search in the Brazilian Health Care Legislation and the Brazilian Health System database was conducted to identify all the inclusion criteria and surgical treatment offered to HIV patients with lipodystrophy, identify all the facilities that offer this, and describe their geographic distribution. In addition, the number of procedures performed was obtained. RESULTS: The inclusion criteria were the following:1 diagnosis of HIV/AIDS and lipodystrophy due to the use of antiretroviral drugs for at least 12 months;2 no response or the impossibility of changing ART;3 clinical stability for six months without clinical manifestations suggestive of immunodeficiency in the last 6 months;4 laboratory results showing CD4 cell count >250 cells/mm3 and viral load <10,000 copies/ml in the last 6 months; and5 stable clinical and laboratory parameters. A total of 4,760 procedures were performed, with the most common procedure being facial filler with polymethylmethacrylate. Eleven hospitals were registered to offer this treatment. CONCLUSION: The Brazilian Health Care System approach to lipodystrophy has an organized plan with universal and integral coverage. All the procedures offered were safe and well-tolerated, according to the literature. However, regional distribution is the main issue and needs to be improved.

RESUMO

Recently, the interest on multifocal avascular necrosis (AVN) among people living with HIV (PLWH) is rising. PLWH have an incidence of symptomatic AVN significantly higher than the general population. The chronic viral infection may induce a direct damage via necrotizing vasculitis, on the other hand the highly active antiretroviral therapy represents a probable risk factor as it can indirectly lead to multifocal necrosis. Regardless of etiopathology, the AVN management in PLWH is the same as in the general population. Depending on symptoms, stage, and location, the AVN can be treated conservatively or surgically, but in its final stages joint replacement is often the most appropriate therapeutic option. The safety and outcomes of such major orthopedic surgery in PLWH are debated topics. In agreement with the literature in our case series we observed, despite some complication, a significant pain relief and excellent recovery of function after hip replacements. Although increased complication rates, several other independent risk factors associated with HIV infection can act as confounding factors. These confounders must be taken into account both in clinical practice and in data analysis. This case-based review highlights the increasing incidence of AVN in PLWH, and emphasizes the safety and effectiveness of the prosthetic joint replacement in this population.

RESUMO

BACKGROUND: Although antiretroviral therapy has significantly altered the natural history of human immunodeficiency virus infection and improved the quality of life of patients, there are conflicting reports regarding its impact on hematological outcomes. Thus, this study aimed at investigating the prevalence and predictors of anemia among adults on antiretroviral therapy in Northeast Ethiopia. MATERIALS AND METHODS: A retrospective cohort study was carried out among adults who began antiretroviral treatment between September 2005 and January 2019 at two governmental hospitals in Dessie town. Data were collected from patients' medical records using a pretested data extraction instrument. Anemia was the primary outcome variable of the study. It was defined based on WHO criteria after adjustment for altitude and smoking status of measured values. Data were entered and validated using EpiData Version 3.1 and then exported to SPSS Version 20.0 for analysis. Descriptive analysis was done for prevalence and binary logistic regression was carried out to assess whether covariates were associated with experiencing anemia. Statistical significance has been considered at p-value <0.05. RESULTS: Medical records of 392 patients (mean age: 35.58 ± 9.46 years) were reviewed. Of the total 392 patients, 218 (55.6%) were females, 261 (66.6%) were categorized under WHO clinical stage III/IV and 134 (34.2%) had a baseline CD4 cell count of <100 cells/mm3. The mean baseline CD4 cell count was 179 cells/mm3 (range: 2 to 853 cells) and 230 (58.7%) of the participants were on zidovudine-based regimen. Anemia was diagnosed among 162 (41.3%) patients. After adjustment for other confounding factors, risk of anemia was significantly associated with low baseline CD4 cell count (AOR 1.80, 95% CI 1.05-3.06) and tenofovir based regimen (AOR 2.05, 95% CI 1.31-3.21). On the other hand, being educated was found to be protective (AOR 0.40, 95% CI 0.21-0.78). CONCLUSION: In this research, the prevalence of anemia was relatively high. Low baseline CD4 cell count and tenofovir based regimen were independent predictors of anemia; while being educated was protective. Treatment programs should focus on early diagnosis and treatment of HIV as well as routine screening and proper treatment of anemia.

RESUMO

HIV-infected patients are more susceptible to cancer due to their immune-compromised condition and HIV infection. Chronic inflammation and immune dysregulation are the main causes of cancer development in these patients. Because of lymphopenia and an immune-compromised condition, most HIV-infected patients with cancer were not considered for cytotoxic therapies, such as chemotherapy and radiotherapy. Immune checkpoint inhibitors (ICIs) have become a game-changer in many cancer types. However, not enough prospective data is available regarding the use of ICIs in HIV-infected patients with cancer. Retrospective data from case reports/series showed that ICIs are safe in HIV-infected patients with cancer.

RESUMO

OBJECTIVES: The aim of the study was to describe time trends in cancer incidence in people living with HIV (PLHIV) in Australia between 1982 and 2012. METHODS: A population-based prospective study was conducted using data linkage between the national HIV and cancer registries. Invasive cancers identified in PLHIV were grouped into AIDS-defining cancers (ADCs), infection-related non-ADCs (NADCs), and non-infection-related NADCs. Crude and age-standardized incidence rates of cancers were calculated and compared over five time periods: 1982-1995, 1996-1999, 2000-2004, 2005-2008 and 2009-2012, roughly reflecting advances in HIV antiretroviral therapy. Standardized incidence ratios (SIRs) compared with the Australian general population were calculated for each time period. Generalized linear models were developed to assess time trends in crude and age-standardized incidences. RESULTS: For ADCs, the crude and age-standardized incidences of Kaposi sarcoma and non-Hodgkin lymphoma substantially declined over time (P-trend < 0.001 for all) but SIRs remained significantly elevated. For infection-related NADCs, there were significant increases in the crude incidences of anal, liver and head and neck cancers. Age-standardized incidences increased for anal cancer (P-trend = 0.002) and liver cancer (P-trend < 0.001). SIRs were significantly elevated for anal cancer, liver cancer and Hodgkin lymphoma. For non-infection-related NADCs, the crude incidence of colorectal, lung and prostate cancers increased over time, but age-standardized incidences remained stable. CONCLUSIONS: Continuous improvements and high coverage of antiretroviral therapy have reduced the incidence of ADCs in PLHIV in Australia. Clinical monitoring of anal and liver cancers in people living with HIV should be performed, given the increasing incidence of these cancers.

RESUMO

OBJECTIVES AND METHODS: : Progressive multifocal leukoencephalopathy (PML) has rarely been reported in people with HIV (PWH) with long-term HIV immune-virological control. We describe the clinical and biological characteristics of patients with confirmed PML among PWH with a CD4+ cell count more than 200 cells/µl and an undetectable HIV RNA viral load after at least 6 months of combined antiretroviral therapy (cART) at the time of PML diagnosis, in the large French multicenter Dat'AIDS cohort. RESULTS: : Among 571 diagnoses of PML reported in the Dat'AIDS cohort between 2000 and 2019, 10 cases (1.75%) occurred in PWH with a CD4+ cell count greater than 200 cells/µl and an undetectable HIV RNA viral load after at least 6 months of cART. Median CD4+ cell count at PML diagnosis was 395 cells/µl (IQR 310-477). The median duration between the last detectable HIV viral load and the PML diagnosis was 41.1 months (IQR 8.2-67.4). Only one patient treated with rituximab-based chemotherapy for a large B-cell lymphoma had an established risk factor for PML. Among the nine other patients with no apparent severe immunodeficiency, multiple factors of impaired immunity could have led to the development of PML: hepatitis C virus (HCV) co-infection (n = 6), cirrhosis (n = 4), HHV-8 co-infection (n = 3) with Kaposi's sarcoma (n = 2) in association with Castleman's disease (n = 1) and indolent IgA multiple myeloma (n = 1). CONCLUSION: : This study highlights that factors other than low CD4+ cell count and high HIV viral load may be associated with the occurrence of PML. Further studies are warranted to investigate in greater detail the immunologic characteristics of PWH with immune-virological control who develop PML.
