Improvement in human immunodeficiency virus-1/acquired immune deficiency syndrome patients' well-being following administration of “Phyto V7”

AIM:To corroborate the capacity of Phyto V7,a complex of phytochemicals,to improve the physical well-being of human immunodeficiency virus-1(HIV-1) infected and acquired immune deficiency syndrome(AIDS) patients not undergoing antiretroviral treatment.METHODS:Two hundred and thirty nine HIV-1 seropositive male and female voluntary inmates were recruited through the Uruguay National Program of AIDS.The study participants received for 90 consecutive days every eight hours two tablets(760 mg/each) of Phyto V7,containing a mix of the following phytochemicals:flavonols(Kaempferol,Quercetin),flavones(Apigenin,Luteolin),hydroxycinnamic acids(ferrulic acid),carotenoids(Lutein,Lycopene,Beta carotene) and organosulfur compounds,all from vegetal origin.The participants did not receive any antiretroviral treatment during the study.At days 0,30,60 and 90(± 2 d) the participants were evaluated for body mass index(BMI),tolerance to Phyto V7 and Index of Quality of Life based on the Karfnosky scale.ANOVA,Tukey Post-test,χ2 test and Wilcoxon Signed Rank test were used to analyze the effect of treatment.RESULTS:One hundred and nighty nine study participants finished the study.Already after 30 d of Phyto V7 consumption,the weight,BMI and Karnofsky score statistically significantly improved(P < 0.001),and continued to improve until the end of the study.The mean weight gain per participant during the 90 d wasof 1.21 kg(approximately 2% of body weight).The overall increase in the mean Karnofsky score after 90 d was 14.08%.The lower the BMI and Karnofsky score of the participants were at the beginning of the study,the more notorious was the improvement over time.For example,the mean increment of Index of Quality of Life,among the participants with an initial Karnofsky score of 5 or below(n = 33) from day 0 to day 90,was of 35.67%(0.476 ± 0.044 vs 0.645 ± 0.09; P < 0.001).The tolerability to Phyto V7 was very good and no adverse reactions were recorded or reported.CONCLUSION:Administration of the Phyto V7 can be an important tool to improve the well-being of HIV-1 seropositive individuals and AIDS patients,not undergoing antiretroviral treatment.

Human immunodeficiency virus/acquired immune deficiency syndrome: Using drug from mathematical perceptive

Entry of acquired immune deficiency syndrome virus into the host immune cell involves the participation of various components of host and viral cell unit. These components may be categorized as attachment of the viral surface envelope protein subunit, gp120, to the CD4+ receptor and chemokine coreceptors, CCR5 and CXCR4, present on T cell surface. The viral fusion protein, gp41, the second cleaved subunit of Env undergoes reconfiguration and the membrane fusion reaction itself. Since the CD4+ T cell population is actively involved; the ultimate outcome of human immunodeficiency virus infection is total collapse of the host immune system. Mathematical modeling of the stages in viral membrane protein-host cell receptor-coreceptor interaction and the effect of antibody vaccine on the viral entry into the susceptible host cell has been carried out using as impulsive differential equations. We have studied the effect of antibody vaccination and determined analytically the threshold value of drug dosage and dosing interval for optimum levels of infection. We have also investigated the effect of perfect adherence of drug dose on the immune cell count in extreme cases and observed that systematic drug dosage of the immune cells leads to longer and improved lives.

Investigation of perceived stigma among people living with human immunodeficiency virus/ acquired immune deficiency syndrome in Henan Province, China

Purpose:To investigate the level of and factors influencing perceived stigma and discrimination among people living with human immunodeficiency virus(HIV)/acquired immune deficiency syndrome(PLWHA)in Henan Province.Methods:In total,161 PLWHA from Zhengzhou and Zhenping were investigated using the Berger HIV stigma scale.Results:The mean Berger stigma scale score was 105.70±15.20,indicating a middle stigma level.Among the four subscales of the Berger stigma scale,the disclosure concerns score was highest,while the negative self-image score was lowest.Multivariate analyses showed that factors influencing perceived HIV stigma included the level of education and route of infection.Conclusion:The level of perceived HIV stigma and discrimination among PLWHA in Henan Province is moderate and was affected by the level of education and route of infection.Special intervention should be established to address this problem.

Elevated homocysteine levels in human immunodeficiency virus-infected patients under antiretroviral therapy: A meta-analysis

AIM: To evaluate the association between the levels of homocysteine(Hcy), folate, vitamin B12 in human immunodeficiency virus(HIV)-infected patients who were treated with antiretroviral therapy(ART) or not treated with ART.METHODS: The Pub Med and Scielo databases were searched. Eligible studies regarding plasma Hcy level in HIV-infected patients were firstly identified. After careful analysis by two independent researches, the identified articles were included in the review according to two outcomes(1) Hcy, folate and vitamin B12 blood concentration in HIV-infected subjects vs health controls and;(2) Hcy blood concentration in HIV-infected subjects under ART vs not treated with ART. RevM an(version 5.2) was employed for data synthesis.RESULTS: A total of 12 studies were included in outcome 1(1649 participants, 932 cases and 717 controls). Outcome 1 meta-analysis demonstrated higher plasma Hcy(2.05 μmol/L; 95% CI: 0.10 to 4.00, P < 0.01) and decreased plasma folate concentrations(-2.74 ng/m L; 95%CI:-5.18 to-0.29, P < 0.01) in HIV-infected patients compared to healthy controls. No changes in vitamin B12 plasma concentration were observed between groups. All studies included in the outcome 2 meta-analysis(1167 participants; 404 HIVinfected exposed to ART and 757 HIV-infected non-ART patients) demonstrated higher mean Hcy concentration in subjects HIV-infected under ART compared to nonART HIV subjects(4.13 μmol/L; 95%CI: 1.34 to 6.92, P < 0.01).CONCLUSION: This meta-analysis demonstrated that the levels of Hcy and folate, but not vitamin B12, were associated with HIV infection. In addition, Hcy levels were higher in HIV-infected patients who were under ART compared to HIV-infected patients who were not exposed to ART. Our results suggest that hyperhomocysteinemia should be included among the several important metabolic disturbances that are associated with ART in patients with HIV infection.

Water,electrolytes,and acid-base alterations in human immunodeficiency virus infected patients

The clinical spectrum of human immunodeficiency virus （HIV） infection associated disease has changed significantly over the past decade, mainly due to the wide availability and improvement of combination antiretroviral therapy regiments. Serious complications associated with profound immunodeficiency are nowa-days fortunately rare in patients with adequate access to care and treatment. However, HIV infected patients, and particularly those with acquired immune defciency syndrome, are predisposed to a host of different water, electrolyte, and acid-base disorders （sometimes with opposite characteristics）, since they have a modified renal physiology （reduced free water clearance, and relatively increased fractional excretion of calcium and magnesium） and they are also exposed to infectious, inflammatory, endocrinological, oncological variables which promote clinical conditions （such as fever,tachypnea, vomiting, diarrhea, polyuria, and delirium）, and may require a variety of medical interventions （antiviral medication, antibiotics, antineoplastic agents）, whose combination predispose them to undermine their homeostatic capability. As many of these disturbances may remain clinically silent until reaching an advanced condition, high awareness is advisable, particularly in patients with late diagnosis, concomitant inflammatory conditions and opportunistic diseases. These disorders contribute to both morbidity and mortality in HIV infected patients.

The default mode network is affected in the early stage of simian immunodeficiency virus infection:a longitudinal study

Acquired immune deficiency syndrome infection can lead to cognitive dysfunction represented by changes in the default mode network.Most recent studies have been cross-sectional and thus have not revealed dynamic changes in the default mode network following acquired immune deficiency syndrome infection and antiretroviral therapy.Specifically,when brain imaging data at only one time point are analyzed,determining the duration at which the default mode network is the most effective following antiretroviral therapy after the occurrence of acquired immune deficiency syndrome.However,because infection times and other factors are often uncertain,longitudinal studies cannot be conducted directly in the clinic.Therefore,in this study,we performed a longitudinal study on the dynamic changes in the default mode network over time in a rhesus monkey model of simian immunodeficiency virus infection.We found marked changes in default mode network connectivity in 11 pairs of regions of interest at baseline and 10 days and 4 weeks after virus inoculation.Significant interactions between treatment and time were observed in the default mode network connectivity of regions of interest pairs area 31/V6.R and area 8/frontal eye field(FEF).L,area 8/FEF.L and caudal temporal parietal occipital area(TPOC).R,and area 31/V6.R and TPOC.L.ART administered 4 weeks after infection not only interrupted the progress of simian immunodeficiency virus infection but also preserved brain function to a large extent.These findings suggest that the default mode network is affected in the early stage of simian immunodeficiency virus infection and that it may serve as a potential biomarker for early changes in brain function and an objective indicator for making early clinical intervention decisions.

Bilateral Central Retinal Vein Occlusions Combined with Artery Occlusions in A Patient with Acquired Immune Deficiency Syndrome

Purpose: This is the first report of a bilateral nonischemic central retinal vein occlusionscombined with artery occlusions in a patient with acquired immune deficiency syndrome(AIDS).

Chinese Herbal Medicine for the Treatment of Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome-Associated Diarrhea: A Protocol for the Systematic Review and Meta-Analysis of Randomized Clinical Trials

Diarrhea can occur at an early or advanced stage of acquired immunodeficiency syndrome(AIDS)as a usual symptom in people with human immunodeficiency virus(HIV)infection.While it is usually not fatal,it can influence patients’quality of life seriously.It has shown to be efficacious and improves people’s immune status to a certain extent to treat HIV/AIDS-related diarrhea on the basis of syndrome differentiation and treatment or Chinese herbs plus conventional treatment.Therefore,it may have a good application potential.Here,we outline a protocol for the systematic review of this health-care intervention,with the aim to evaluate the beneficial effects and safety of Traditional Chinese Medicine(TCM)for patients who suffer from HIV/AIDS-associated diarrhea.Randomized controlled trials that compare Chinese herbs with placebo or other effective treatments will be searched and included,in spite of publication status or language.The primary outcomes include diarrhea frequency and fecal character.The databases we will search as follows:China Science and Technology Journal Database(VIP),Chinese Biomedical Literature Database(Sino Med),Wanfang Data,China National Knowledge Infrastructure,Pub Med and the CENTRAL in Cochrane Library.Two authors will respectively conduct the screening of trials,data extraction,and use the Cochrane risk of bias tool to assess the methodological quality.We will analyze the data and perform a meta-analysis if possible.We intend to identify potential therapeutic modalities that may be of benefit to inform clinical practice by supplying existing evidence of the helpful effects and safety of TCM to treat patients suffering from HIV/AIDS-associated diarrhea.

Factors Associated with Antiretroviral Therapy Defaulting among Adult Patients Receiving Care at Chikankata Mission Hospital, Chikankata District, Zambia

Background: Defaulting on antiretroviral therapy has been identified as the most important factor contributing to the antiretroviral therapy failure rate. This study aimed to investigate factors associated with defaulting on antiretroviral therapy among adult patients receiving care at Chikankata Mission Hospital antiretroviral therapy clinic. Method: Cross-sectional analytical study on 385 participants selected by a computer generated random numbers technique of simple random sampling from among the patients receiving antiretroviral therapy at Chikankata Mission Hospital. Data collected were processed and analysed using Statistical Package for Social Science version 27. Univariate and backward multivariable logistic regression analysis was performed to identify factors associated with antiretroviral therapy defaulting. The level of significance was set at 5% with a confidence level of 95%. Results: Over half (58.4%) of the study participants defaulted on antiretroviral therapy. About 65.8% of study participants indicated improved health as the reason they defaulted on antiretroviral therapy. Most participants indicated that it was important to always go for antiretroviral therapy services (Adjusted Odds Ratio 1.95;95% Confidence Interval: [1.14 - 3.33], p = 0.015). Very few participants indicated poor family support for antiretroviral therapy services (Adjusted Odds Ratio 4.08;95% Confidence Interval: [2.02 - 8.23], p Conclusion: Defaulting on antiretroviral therapy continues to be a significant problem and needs to be addressed as a matter of priority. More counselling and awareness-raising programmes are required to improve knowledge and understanding on the importance of attending scheduled antiretroviral therapy clinics and services as well as the consequences of defaulting on antiretroviral therapy.

Fighting against Acquired Immunodeficiency Syndrome with Chinese Medicine:A Perspective from China

Continuing expansion of the human immunodeficiency virus （HIV）/ acquired immunodeficiency syndrome （AIDS） pandemic has been recognized as an exceptional challenge to global health. Taking highly active antiretroviral treatment （HAART）, a confirmed effective treatment, has its limitations. While a much cheaper and potential treatment--the Chinese medicine （CM） has not been paid enough attention from the worldwide. We explained the CM viewpoints about pathology and etiology to answer some questions about whether and how CM can treat AIDS. Some herbal formulae and their targeted patterns and common symptoms were also introduced. Chinese government has realized the important role of CM as an independent therapy for early management, bolstering immune-system functions depressed by HIV, and has funded large randomized double-blind controlled clinical trials to more accurately assess the benefits, and valued the fundamental research to establish a quantitative standardization of pattern diagnosis. Researchers of CM are looking for cooperation with all the world＇s top experts in the areas of AIDS and immunity to strive for victories in the fight against AIDS.

Activation-induced pyroptosis contributes to the loss of MAIT cells in chronic HIV-1 infected patients

Background: Mucosal-associated invariant T(MAIT) cells are systemically depleted in human immunodeficiency virus type 1(HIV-1) infected patients and are not replenished even after successful combined antiretroviral therapy(cART).This study aimed to identify the mechanism underlying MAIT cell depletion.Methods: In the present study, we applied flow cytometry, single-cell RNA sequencing and immunohistochemical staining to evaluate the characteristics of pyroptotic MAIT cells in a total of 127 HIV-1 infected individuals, including 69 treatment-naive patients, 28 complete responders, 15 immunological non-responders, and 15 elite controllers, at the Fifth Medical Center of Chinese PLA General Hospital, Beijing, China.Results: Single-cell transcriptomic profiles revealed that circulating MAIT cells from HIV-1 infected subjects were highly activated, with upregulation of pyroptosis-related genes. Further analysis revealed that increased frequencies of pyroptotic MAIT cells correlated with markers of systemic T-cell activation, microbial translocation, and intestinal damage in cART-naive patients and poor CD4+ T-cell recovery in long-term cART patients. Immunohistochemical staining revealed that MAIT cells in the gut mucosa of HIV-1 infected patients exhibited a strong active gasdermin-D(GSDMD, marker of pyroptosis) signal near the cavity side, suggesting that these MAIT cells underwent active pyroptosis in the colorectal mucosa. Increased levels of the proinflammatory cytokines interleukin-12(IL-12) and IL-18 were observed in HIV-1 infected patients. In addition, activated MAIT cells exhibited an increased pyroptotic phenotype after being triggered by HIV-1 virions, T-cell receptor signals, IL-12 plus IL-18, and combinations of these factors, in vitro.Conclusions: Activation-induced MAIT cell pyroptosis contributes to the loss of MAIT cells in HIV-1 infected patients,which could potentiate disease progression and poor immune reconstitution.

Fundus manifestations and HIV viral loads of AIDS patients before and after HAART

AIM: To investigate the fundus manifestations and human immunodeficiency virus(HIV) viral loads of acquired immune deficiency syndrome(AIDS) patients before and after highly active antiretroviral therapy(HAART).METHODS: This retrospective study included 21 AIDS patients(42 eyes) who presented to the Department of Ophthalmology, Peking Union Medical College Hospital, from 2007 to 2011. Among the patients, 16 showed a good response to HAART, 3 presented drug resistance and 2 were pre-HAART. All patients underwent comprehensive ophthalmic examinations. The HIV viral loads and the CD4+ T-cell counts were also determined.RESULTS: The best-corrected visual acuity(BCVA) of 38 eyes(19 patients) was improved, and cytomegalovirus retinitis(CMVR) in 5 eyes(3 patients) regressed after HAART. Furthermore, 16 patients treated with effective HAART had decreased plasma HIV viral loads(<78 copies/mL)and increased CD4+ T-cell counts(343±161 cells/μL, P<0.005), but the HIV viral load in tears was still detected at 2404 copies/mL. The CD4+ T-cell count was lower in the CMVR group than in the non-CMVR group(P=0.022), but the HIV viral load in the tears was not significantly different between the two groups(P=0.439).CONCLUSION: Most patients with AIDS show a good viral response with a decreased HIV viral load and an increased CD4+ T-cell count in plasma after HAART. However, the HIV viral load remain quite high in the tear samples. Based on our results, we suggest that AIDS patients undergo long-term HAART that should not be interrupted.

A rare cause of drug-induced hepatitis in an immunocompromised patient and the role of glutathione

The Food and Drug Administration (FDA) has issued a warning on numerous herbal drugs, including many popular products at General Nutrition Centers (GNC), regarding unstudied hepatotoxicity. There have been recent reports of GNC products such as hydroxycut and herbalife, causing drug-induced hepatitis. Herbal medications are over-the-counter products and are not investigated thoroughly by the FDA. Given that the mostcommon outpatient laboratory abnormality is elevated liver transaminases, a sign of hepatocellular toxicity; it is not surprising that some of these products end up causing hepatic dysfunction, especially when taken in large volume. There are numerous herbal supplements that are hepatotoxic, however, these medications have a much more significant effect in human immunodeficiency virus (HIV)/ acquired immune deficiency syndrome patients, which is secondary to depleted glutathione. We present a rare case of drug induced hepatitis secondary to herbal medications used to treat HIV and elucidate the role of glutathione depletion in immunocompromised patients.
