Impact of Herbal Preparations on Outcomes of Highly Active Antiretroviral Therapy: A One-Year Prospective Cohort Study. Chin J Integr Med 2019; 26:497-501. [PMID: 30941681 DOI: 10.1007/s11655-019-3156-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/05/2018] [Indexed: 10/27/2022]
Abstract
OBJECTIVE To investigate the impacts of two herbal preparations for human immunodeficiency virus/aquired immune deficiency syndrome (HIV/AIDS) patients, Shenling Fuzheng Capsule (, SLFZC) and Qingdu Capsule (, QDC), on the efficacy of highly active antiretroviral therapy (HAART). METHODS HIV/AIDS patients met the criteria were all enrolled in a 1-year cohort study, in which patients receiving HAART alone were designated as Group A, those receiving HAART in combination with SLFZC were designated as Group B, and those receiving HAART in combination with QDC were designated as Group C, 100 cases in each group. The dose of SLFZC was 1.48 g (4 capsules), 3 times daily, and QDC 1.56 g (4 capsules), 3 times daily. T cell subsets, HIV RNA and HIV-1 drug resistance were detected at enrollment and 1 year after treatment. Patients were followed up every 3 months, during which side-effects and other clinical data were recorded. RESULTS After 1-year treatment, the median increment in CD4 counts was 165.0, 178.0 and 145.0 cells/μL for Group A, B and C, respectively. HIV RNA was undetectable in 94% of patients in Group A, 96% in Group B and 92% in Group C. There were no differences regarding the increment in CD4 counts, HIV RNA and frequency of HIV-1 drug resistance mutations. Two of the 14 suspected side-effect symptoms, i.e. fatigue and dizziness, were lower in Groups B and C than in Group A (P<0.05, respectively) CONCLUSIONS: SLFZC and QDC do not have a negative impact on immunological and virological response to HAART; however, these preparations are not as potent in reducing HAART-associated side-effects as anticipated.

Decolonising the mindsets, attitudes and practices of the allopathic and indigenous health practitioners in postcolonial society: An exploratory approach in the management of patients. Afr J Prim Health Care Fam Med 2018; 10:e1-e8. [PMID: 29943598 PMCID: PMC6018654 DOI: 10.4102/phcfm.v10i1.1518] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2017] [Revised: 02/08/2018] [Accepted: 02/17/2018] [Indexed: 12/04/2022] Open
Abstract
Background The indigenous health care system continues in the postcolonial era to be perceived by antagonists as a threat to Western medicine. It has been associated with ‘witchcraft’, actively discouraged and repressed through official government prohibition laws. Despite that, human immunodeficiency virus and acquired immunodeficiency syndrome (HIV and AIDS) patients consult both allopathic and indigenous health practitioners. Aim The study explored a collaboration model between allopathic and traditional health practitioners in the management of patients living with HIV and AIDS in postcolonial South Africa. Setting We conducted six combined focus group discussions and four separate group discussions with each category of co-researchers. Methods Combined and separate focus group discussions were conducted with community members, allopathic and indigenous health practitioners, applying the cyclical method in the decolonisation process. Their perceptions and experiences in the management of HIV and AIDS patients were explored, and finally decolonisation strategies suitable for collaboration in their context were identified. Results The two health systems were rendering services to the same HIV and AIDS communities. Lack of communication created confusion. Collaboration was long overdue. A change in mindsets, attitudes and practices among practitioners was critical, with an acknowledgement that ‘neither health system is better than the other, but the two should be complementary, recognising that the culture and beliefs of patients influence their health-seeking behaviour’. Conclusion Co-researchers were committed to working together in the fight against HIV and AIDS infections. Their model for collaboration addresses the challenges of patients’ secrecy, treatment overdose and the abandonment of antiretroviral treatment. Through the application of a decolonisation process, their mindsets, attitudes and practices towards each other were changed, enabling the joint development of a custom model for collaboration between allopathic health practitioners and indigenous health practitioners in the management of patients living with HIV and AIDS.

Abstract
Given the challenges in exploring lifelong therapy with little side effect for human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) cases, there is increasing interest in developing traditional Chinese medicine (TCM) treatments based on specific TCM syndrome. However, there are few objective and biological evidences for classification and diagnosis of HIV/AIDS TCM syndromes to date. In this study, iTRAQ-2DLC-MS/MS coupled with bioinformatics were firstly employed for comparative proteomic profiling of top popular TCM syndromes of HIV/AIDS: accumulation of heat-toxicity (AHT) and Yang deficiency of spleen and kidney (YDSK). It was found that for the two TCM syndromes, the identified differential expressed proteins (DEPs) as well as their biological function distributions and participation in signaling pathways were significantly different, providing biological evidence for the classification of HIV/AIDS TCM syndromes. Furthermore, the TCM syndrome-specific DEPs were confirmed as biomarkers based on western blot analyses, including FN1, GPX3, KRT10 for AHT and RBP4, ApoE, KNG1 for YDSK. These biomarkers also biologically linked with the specific TCM syndrome closely. Thus the clinical and biological basis for differentiation and diagnosis of HIV/AIDs TCM syndromes were provided for the first time, providing more opportunities for stable exertion and better application of TCM efficacy and superiority in HIV/AIDS treatment.

Abstract
Herbal medicines are currently in high demand, and their popularity is steadily increasing. Because of their perceived effectiveness, fewer side effects and relatively low cost, they are being used for the management of numerous medical conditions. However, they are capable of affecting the pharmacokinetics and pharmacodynamics of coadministered conventional drugs. These interactions are particularly of clinically relevance when metabolizing enzymes and xenobiotic transporters, which are responsible for the fate of many drugs, are induced or inhibited, sometimes resulting in unexpected outcomes. This article discusses the general use of herbal medicines in the management of several ailments, their concurrent use with conventional therapy, mechanisms underlying herb-drug interactions (HDIs) as well as the drawbacks of herbal remedy use. The authors also suggest means of surveillance and safety monitoring of herbal medicines. Contrary to popular belief that "herbal medicines are totally safe," we are of the view that they are capable of causing significant toxic effects and altered pharmaceutical outcomes when coadministered with conventional medicines. Due to the paucity of information as well as sometimes conflicting reports on HDIs, much more research in this field is needed. The authors further suggest the need to standardize and better regulate herbal medicines in order to ensure their safety and efficacy when used alone or in combination with conventional drugs.

Abstract
The human immunodeficiency virus (HIV) infects cells of the immune system and destroys their function. Approximately, 2 million people die every year from HIV as reported by the World Health Organization. HIV/AIDS is difficult to treat as the virus continuously develops resistance to drugs being developed. Approach is now turning toward natural products for the development of anti-HIV drugs. Although HIV/AIDS is not a new disease, but research based on plant-derived products is still under clinical trials. Experimentally, it has been proven that plants have the potential for HIV treatment. The process involves identification of the active ingredients responsible for the reported anti-HIV activities, testing of the extract, and development of appropriate bioassays. Further development would require optimization of the formulation and manufacturing in compliance with preclinical safety and efficacy testing. The most challenging task for the natural product scientists is to separate these highly complex extracts containing several compounds into its individual components that are biologically active. Recently developed direct binding assay with mass spectrometry (MS) technology (viz., real-time time-of-flight-MS) is helpful in this respect but needs extensive optimization. At present, we have compiled all the information for the various phytochemicals present in Terminalia catappa having anti-HIV properties. These include tannins, gallotannins, ellagitannins, cyanidin, and flavonoids. Further, we have also discussed their pharmacological as well as pharmacokinetics studies.

Abstract
To respond to the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) epidemic in China, the integration of antiretroviral therapy (ART) and traditional Chinese medicine (TCM) has important implications in health outcomes, especially in China where the use of TCM is widespread. The National Free TCM Pilot Program for HIV Infected People began in 5 provinces (Henan, Hebei, Anhui, Hubei, and Guangdong) in 2004, and quickly scaled up to 19 provinces, autonomous regions, and municipalities in China including some places with high prevalence, 26,276 adults have been treated thus far. Usually, people with HIV infection seek TCM for four main reasons: to enhance immune function, to treat symptoms, to improve quality of life, and to reduce side effects related to medications. Evidences from randomized controlled clinical trials suggested some beneficial effects of use of traditional Chinese herbal medicine for HIV infections and AIDS. More proofs from large, well-designed, rigorous trials is needed to give firm support. Challenges include interaction between herbs and antiretroviral drugs, stigma and discrimination. The Free TCM Program has made considerable progress in providing the necessary alternative care and treatment for HIV-infected people in China, and has strong government support for continued improvement and expansion, establishing and improving a work mechanism integrating Chinese and Western medicines.

Abstract
This study aimed to evaluate the therapeutic effect of traditional Chinese medicine (TCM) by observing the changes in CD4 T-lymphocyte cell count of 110 cases with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) treated continuously with TCM for 84 months. Information of 110 HIV/AIDS patients from 19 provinces and cities treated with TCM from 2004 to 2013 was collected. Changes in the indexes of CD4 counts ( ≤ 200, 201-350, 351-500 and > 500 cells/mm(3)) at five time points (0, 12, 36, 60 and 84 months) and different treatments [TCM and TCM plus antiretroviral therapy (ART)] were compared. Repeated measures test indicated no interaction between group and time (P > 0.05). Degrees of increasing and decreasing CD4 count of the two groups at four different frames were statistically significant compared with the baseline. The CD4 count between the two groups was not statistically significant. For CD4 count of ≤ 200 cells/mm(3), the mean CD4 count changes were 21 and 28 cells/mm(3) per year for the TCM group and TCM plus ART group, respectively. For CD4 count of 201-350 cells/mm(3), the mean CD4 count changes were 6 and 25 cells/mm(3) per year for the TCM group and TCM plus ART group, respectively. For CD4 count of 351-500 cells/mm(3), the mean CD4 count changes were -13 and -7 cells/mm(3) per year for the TCM group and TCM plus ART group, respectively. For CD4 count of > 500 cells/mm(3), the mean CD4 count changes were -34 and -17 cells/mm(3) per year for the TCM group and TCM plus ART group, respectively. Long-term use of TCM could maintain or slow the pace of declining CD4 counts in patients with HIV/AIDS, and may achieve lasting effectiveness.

Abstract
Highly active antiretroviral therapy (HAART) has been successful in reducing human immunodeficiency virus (HIV)-1-associated morbidity and mortality since its introduction in 1996. However, it fails to eradicate HIV-1 infection. The high cost of life-long highly active antiretroviral therapy and the emergence of drug resistance among HIV-1-infected individuals have brought renewed pressure for the discovery of novel antivirals and alternative medicines. Traditional Chinese medicine (TCM) is a complementary and alternative medicine, and serves as a rich resource for new drug development. Despite the almost 100 plant-derived compounds that are in clinical trials, few target HIV-1 infection. In this study, we discovered that Sanguisorba officinalis extract (SOE) has anti-HIV-1 properties. Using a cell-based assay and single-cycle luciferase reporter viruses pseudotyped with envelopes from HIV-1 or control viruses, we found that SOE exhibited significant inhibitory ability against both CCR5 and CXCR4 tropic HIV-1 (ADA and HXB2), with respective IC50 values of 1.91 ± 0.16 μg/mL and 3.70 ± 0.53 μg/mL. SOE also inhibited simian immunodeficiency virus infection but failed to block vesicular stomatitis virus, severe acute respiratory syndrome coronavirus, and influenza H5N1 pseudoviruses. Furthermore, we showed that SOE had no effect on postentry events of HIV-1 replication. Because SOE pretreatment with the virus but not with cell lines expressing viral receptors showed the maximal inhibitory activity, we can state that SOE probably blocks entry by acting on the viral envelope directly. In addition, SOE was able to inhibit reverse transcriptase inhibitor resistant viruses (K103N, Y188L, and K103N/Y188L/G190A) and a protease inhibitor resistant strain (PI-2840). Our findings demonstrate SOE as a novel and specific entry inhibitor, which sheds light on the discovery of anti-HIV-1 drugs from traditional herbal medicines.

Abstract
To assess the effects of TCHM on patients with HIV infection and AIDS, we reviewed eleven randomized placebo-controlled trials involving 998 patients. Due to the limited number of RCTs for included trials and the small sample size of each study, we are not able to draw firm conclusions concerning TCHM therapy in treating patients with HIV infection and AIDS. However, some high-quality clinical studies do exist.
Studies of diarrhea and oral candidiasis, which are challenging symptoms of AIDS, were demonstrated to have positive effects. Study of peripheral leukocytes, which are a side effect of antiretroviral drugs, suggested that an integrated treatment approach may be of benefit. The overall methodological quality of the trials was adequate; however, randomization methods should be clearly described and fully reported in these trials according to the Consolidated Standards of Reporting Trials (CONSORT).

Abstract
Chinese herbal medicines are often applied as an alternative therapy for viral diseases. However, the development of anti-HIV herbal drugs has proceeded slowly, partly because of the lack of a high-throughput system for screening these drugs. The present study evaluated 16 herbal medicines for anti-HIV activities in vitro and in vivo. Herbal medicines were first screened for the ability to regulate C-X-C receptor 4 (CXCR4) and C-C receptor 5 (CCR5) promoter activities. A single-round pseudotyped HIV-luciferase reporter virus system (HIV-Luc) was used to identify potential anti-HIV mechanisms. CD4+ T cells from healthy volunteers were examined for changes in CXCR4 and CCR5 levels. HIV-1 replication was evaluated by ELISA. Spica Prunellae and Herba Andrographitis were found to down-regulate the activities of both the CXCR4 and CCR5 promoters. Also, Spica Prunellae and Herba Andrographitis (>1000 μM) inhibited HIV-1 in a dose-dependent manner. CXCR4 and CCR5 levels were reduced in CD4+ T cells from healthy volunteers (p<0.05). Spica Prunellae and Herba Andrographitis (EC₅₀: 3.18 and 5.49 μg/mL, respectively) could suppress cell fusion and decrease p24 antigen. In conclusion, the data demonstrated that Spica Prunellae and Herba Andrographitis possessed anti-HIV-1 capabilities, perhaps through the inhibition of the CXCR4 and CCR5 promoters and HIV-1 replication.

Abstract
This study was to determine the effectiveness (CD4 count and viral load) of a safe herbal concoction, α-Zam used by clients seeking herbal remedy for treatment of HIV infection in Nigeria. 51 patients taking α-Zam as complementary and alternative therapy through the herbal therapist were studied for a period of 16 months. Preliminary medical and laboratory examinations using WHO and CDC criteria were done after confirmation of HIV infection by Western blotting in the nearest teaching hospitals to the residence of the patients. Regular visits were paid to the patients after commencement of the α-Zam to assess the side-effects, drug interactions, toxicity and effectiveness of the herbal remedy. There was a statistical significance (P<0.05) between pre-treatment and post-treatment CD4 count. 4 (7.8%) of the patients had average increase in CD4 count of 262±16 cell/µL, 23 (45.1%) patients with average increase 310±16 cell/µL, 16 (31.4%) patients with average increase 456±25 cell/µL and 8 (15.7%) patients with average increase 510±36 cell/µL( %) were at WHO staging I , II, III and IV respectively within 4 months on herbal therapy. There was very marked reduction in viral (HIV-RNA) load with 41 (80.4%) and10 (19.6%) HIV infected patients had undetectable viral load and <1000 copies/ml respectively after the therapy. All symptoms and signs associated with HIV infection in all patients fully subsided within 4 weeks of commencement of α-Zam therapy and there was no evidence of negative drug interaction in those HIV patients using both the herbal and highly active anti-retroviral therapy (HAART). The study is in progress to determine periodic immunological outcomes of post therapy in all patients.

Abstract
Background Highly active anti-retroviral therapy (HAART) is the current HIV/AIDS treatment modality. Despite the fact that HAART is very effective in suppressing HIV-1 replication and reducing the mortality of HIV/AIDS patients, it has become increasingly clear that HAART does not offer an ultimate cure to HIV/AIDS. The high cost of the HAART regimen has impeded its delivery to over 90% of the HIV/AIDS population in the world. This reality has urgently called for the need to develop inexpensive alternative anti-HIV/AIDS therapy. This need has further manifested by recent clinical trial failures in anti-HIV-1 vaccines and microbicides. In the current study, we characterized a panel of extracts of traditional Chinese medicinal herbal plants for their activities against HIV-1 replication. Methods Crude and fractionated extracts were prepared from various parts of nine traditional Chinese medicinal herbal plants in Hainan Island, China. These extracts were first screened for their anti-HIV activity and cytotoxicity in human CD4+ Jurkat cells. Then, a single-round pseudotyped HIV-luciferase reporter virus system (HIV-Luc) was used to identify potential anti-HIV mechanisms of these extracts. Results Two extracts, one from Euphorbiaceae, Trigonostema xyphophylloides (TXE) and one from Dipterocarpaceae, Vatica astrotricha (VAD) inhibited HIV-1 replication and syncytia formation in CD4+ Jurkat cells, and had little adverse effects on host cell proliferation and survival. TXE and VAD did not show any direct inhibitory effects on the HIV-1 RT enzymatic activity. Treatment of these two extracts during the infection significantly blocked infection of the reporter virus. However, pre-treatment of the reporter virus with the extracts and treatment of the extracts post-infection had little effects on the infectivity or gene expression of the reporter virus. Conclusion These results demonstrate that TXE and VAD inhibit HIV-1 replication likely by blocking HIV-1 interaction with target cells, i.e., the interaction between gp120 and CD4/CCR5 or gp120 and CD4/CXCR4 and point to the potential of developing these two extracts to be HIV-1 entry inhibitors.

Abstract
Immunoxel (Dzherelo™) is an oral, herbal immunomodulator used in Ukraine for adjunct therapy of infectious and autoimmune diseases. Antiretroviral drug-naive, tuberculosis (TB)/HIV coinfected patients with active pulmonary TB were divided into two arms, A (n = 20) and B (n = 20), to receive first-line anti-TB therapy (ATT) or ATT + Dzherelo, respectively. As a result, three (16%) versus 12 (67%; p = 0.003) patients had Mycobacterium tuberculosis culture conversion, with time to negative culture of 6 and 4 months in arms A and B, respectively. In the ATT-alone arm, the healing of pulmonary cavitations was observed in 25% of patients at weeks 24–28, while 60% of individuals in arm B healed at 16–18 weeks (p = 0.025). The TB lesions, on chest x-ray, had cleared in 46 and 84%, with time-to-clearance of 24–28 and 16–18 weeks in arms A and B, respectively. In the ATT-alone arm, the bodyweight at baseline was 64 ± 6.3 kg, with 13 cachexic patients who had an average weight deficit of -5.2 ± 1.7 kg. At the end of 6 months of follow-up, they have lost an additional 0.6 kg (-5.8 ± 2.4). The study entry-level weight in arm B was 52 ± 5.7 kg, with 12 individuals who had a body mass deficit of -8.5 ± 2.7 kg. The immunotherapeutic intervention increased bodyweight by an average of 5.8 ± 2.6 kg above baseline (p < 0.0001). The inclusion of Dzherelo into the ATT regimen decreased the incidence of new opportunistic infections (OI) with three episodes of OI versus 12 in arm A (p = 0.003). These findings indicate that Dzherelo contributes positively to the clinical efficacy of TB drugs.

Abstract
In India, little is known about health care-seeking behavior among HIV-infected individuals. Similarly, little is known about how HIV is being treated in the community, in particular by Indian Systems of Medicine (ISM) providers. Therefore, while ART implementation programs continue to expand, it is important to determine whether the knowledge, attitudes, and treatment practices of HIV-infected individuals and their health care providers are aligned with current treatment recommendations. We conducted in-depth qualitative interviews with persons with HIV (n = 9 men and 17 women), family members of persons with HIV (n = 14 men and 3 women), and ISM providers (n = 7). Many of the patients we studied turned at some point to ISM providers because they believed that such practitioners offer a cure for HIV. ISM treatments sometimes had negative impacts including side effects, unchecked progression of an underlying illness, and financial depletion. Indian women tended to be less knowledgeable about HIV and HIV treatments, and had less access to financial and other resources, than men. Finally, most of the ISM providers reported dangerous misconceptions about HIV transmission, diagnosis, and treatment. While the existence of ART in India is potentially of great benefit to those with HIV infection, this study shows that a variety of social, cultural and governmental barriers may interfere with the effective use of these therapies. Partnerships between the allopathic and traditional/complementary health sectors in research, policy, and practice are essential in building comprehensive HIV/AIDS treatment strategies.

Abstract
Background Traditional medicine use has been reported is common among individuals with moderate and advanced HIV disease. The aim of this cross-sectional study was to assess the use of Traditional Complementary and Alternative Medicine (TCAM) for HIV patients prior to initiating antiretroviral therapy in three public hospitals in KwaZulu-Natal, South Africa. Methods Using systematic sampling, 618 HIV-positive patients were selected from outpatient departments from three hospitals and interviewed with a questionnaire. Results TCAM was commonly used for HIV in the past six months by study participants (317, 51.3%) and herbal therapies alone (183, 29.6%). The use of micronutrients (42.9%) was excluded from TCAM since mostly vitamins were provided by the health facility. Herbal therapies were the most expensive, costing on average 128 Rand (US$16) per patient per month. Most participants (90%) indicated that their health care provider was not aware that they were taking herbal therapies for HIV (90%). Herbal therapies were mainly used for pain relief (87.1%) and spiritual practices or prayer for stress relief (77.6%). Multivariate logistic regression with use of herbs for HIV as the dependent variable identified being on a disability grant and fewer clinic visits to be associated with use of herbs, and TCAM use for HIV identified being on a disability grant, number of HIV symptoms and family members not contributing to main source of household income to be associated with TCAM use. Conclusion Traditional herbal therapies and TCAM are commonly used by HIV treatment naïve outpatients of public health facilities in South Africa. Health care providers should routinely screen patients on TCAM use when initiating ART and also during follow-up and monitoring keeping in mind that these patients may not fully disclose other therapies.
