Acute and subacute toxicity profile of ethanolic stem bark extract of Albizia coriaria Welw. ex Oliv. in Wistar albino rats. Toxicol Rep 2024; 12:178-185. [PMID: 38304700 PMCID: PMC10832497 DOI: 10.1016/j.toxrep.2024.01.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 11/20/2023] [Accepted: 01/10/2024] [Indexed: 02/03/2024] Open
Abstract
Albizia coriaria (Fabaceae) crude extracts are key ingredients of several licensed and unlicensed herbal products in East Africa. However, there is limited and often contradicting information regarding its toxicity. We therefore evaluated the acute and subacute toxicity of the ethanolic stem bark extract of A. coriaria in mature healthy Wistar albino rats following Lorke's method and OECD guidelines 407. The LD50 of the ethanolic stem bark extract of A. coriaria was 2000 mg/kg. The acute toxicity signs observed included piloerection, hyperventilation, lethargy, and loss of righting reflex. There was a significant increase in aspartate aminotransferase, alkaline phosphatase, red blood cells and haemoglobin in rats after 28 days at the dose of 500 mg/kg. Histological analyses revealed multifocal random parenchymal necrosis and scattered periportal mononuclear inflammatory cells infiltration in the liver, interstitial nephritis in the kidney and multifocal lymphoid accumulation in the peribronchiolar and perivascular lung tissue at 500 mg/kg. The ethanolic stem bark of A. coriaria was therefore moderately toxic to the rats when administered in a single high oral dose within 24 h. The extract caused a dose dependent toxicity with significant damage to the kidney, liver and lung tissues at a dose of 500 mg/kg after 28 days. Herbal medicines containing A. coriaria extracts should be consumed cautiously due to likelihood of toxicity particularly at higher doses greater than 500 mg/kg.

Abstract
BACKGROUND Malaria, a treatable disease mainly caused by Plasmodium falciparum has remained a health challenge in Africa, a continent that accounted for 96% of total global cases and deaths in 2021. Uganda, a malaria endemic country is experiencing malaria parasite resistance to some of the drugs used in the artemisinin-based combination therapy (ACT). In an effort to prioritize herbal medicines for new product development, this review synthesized the available safety and efficacy literature on the Ugandan anti-malarial plants to suggest most effective herbal plants. METHODS Literature was exhaustively searched using engines and databases, such as Google scholar, Pubmed, and Scopus-indexed journals during the period of June 2020-December 2021. In the first phase, information on ethnobotanical uses of anti-malarial plants in Uganda was gathered and synthetized to generate a list of plants, followed by data on anti-malarial efficacy (both in vitro and in vivo) on each listed plant. Minimum inhibitory concentrations (µg/ml), and % parasite suppression for every plant were scored using The Research Initiative on Traditional and Antimalarial Methods (RITAM) scoring system. The best twenty (20) plants were evaluated for acute safety (LD50) data in rat model, plant parts used, ease of cultivation, presence of clinical studies and other relevant factors for suggesting the best three (3) plants for future anti-malarial product development. RESULTS Over one hundred twenty-six (126) plant species are used in Uganda for treatment of malaria in local communities. Out of these, about 33% (41) have been studied for efficacy and safety, with Artemisia annua and Vernonia amygdalina being the most extensively studied and among the best twenty (20) anti-malarial plants in Uganda. Both are limited by parasite recrudescence in clinical studies. Microglossa pyrifolia, a very potent plant (IC50 = 0.03 - 0.05 µg/ml has potential to penetrate the liver and could ameliorate the challenge of recrudescence if combined with A. annua and V. amygdalina in a polyherbal formulation. CONCLUSION There are many plants with promising potential for malaria treatment in Uganda and a herbal combination of A. annua, V. amydalina and M. pyrifolia could offer the next herbal ACT if carefully studied and developed.

Abstract
Introduction Following chronic inflammation and other disease specific factors, the risk of liver disease is believed to be higher among HIV-infected patients than in the general population despite shared risk factors. Understanding this differentiated burden and its drivers will inform policy and priority populations for intervention. Methods This was a cross sectional study among 516 adults attending care clinics in Kampala Uganda. Significant liver fibrosis (SLF) was defined as liver stiffness measurement ≥7.2 KPa identified by Fibroscan®. Data analyses were stratified by HIV status and we performed logistic regression performed to identify correlates. Results The prevalence of SLF was higher among HIV un-infected patients ((24% Vs 14%; p0.004). Overall HIV-uninfected patients were more likely to be overweight and or obese, with elevated serum cholesterol levels. Elevated measurement of fatty change in the liver (CAP scores >248 dB/m) was associated with SLF among HIV un-infected patients (OR 2.3 CI (1.0-5.2); p = 0.046). Low nadir CD4 counts (200cell/mm3) was predictive of SLF among HIV-infected patients (OR 3.3 CI (1.0-10.7); p = 0.05). Conclusion The prevalence of SLF was unexpectedly higher among HIV un-infected than HIV affected patients attending care clinics in urban Uganda. This observed burden is most likely driven by non-alcoholic fatty liver disease (NAFLD) resulting from metabolic syndrome.

Abstract
INTRODUCTION Herbal medication use among patients with COVID-19 imposes a significant risk of drug-herbal interactions and adverse events. This study aimed to assess the prevalence and factors associated with herbal medicine use among patients hospitalized with COVID-19 attending two large COVID-19 Treatment Units (CTU) in Uganda. METHODS A hospital-based descriptive cross-sectional study was conducted recruiting patients with COVID-19 hospitalized at the Mulago National Referral Hospital and Namboole Stadium CTUs. Chi-square or Fishers' exact test for categorical and Mann-Whitney U-test for numerical were used to determine the association between dependent and independent variables. RESULTS The study was terminated early because of significant reduction in the number of patients hospitalized with COVID-19 and the closure of Namboole CTU. Of the anticipated 422 participants, we recruited 108 (25.6%). Of this, 58 (53.7%) were female, with a median age of 38 (range: 20-75) years. Forty-nine (45.4%) had received at least one dose of the COVID-19 vaccine. Fifty-eight (57.3%) of the participants had ever used herbal medicine and the majority had used them in the past 12 months (71.9%, n = 41) either before the diagnosis of COVID-19 (85.4%, n = 35) or after (36.6%, n = 15). Being vaccinated for COVID-19 (adjusted odds ratio (aOR): 3.1, 95% confidence interval (CI): 1.4-6.8, p = 0.005) and having attained tertiary level of education (aOR: 6.2, 95% CI: 1.7-23.1, p = 0.006), as well as the accessibility to herbalists (aOR: 31.2, 95% CI: 3.7-263.2, p = 0.002) were significantly associated with herbal medication use. The majority of participants reported some improvement after using herbal medicine (80.7%, n = 46) and their doctors or nurses asked almost half of the participants about herbal medicine use (49.5%, n = 53). CONCLUSION The use of herbal medicines to treat or prevent COVID-19 among hospitalized patients is a widespread practice in Uganda amidst unpublished evidence of their safety and efficacy.

Abstract
Global health partnerships between high-income countries and low/middle-income countries can mirror colonial relationships. The growing call to advance global health equity therefore involves decolonising global health partnerships and outreach. Through decolonisation, local and international global health partners recognise non-western forms of knowledge and authority, acknowledge discrimination and disrupt colonial structures and legacies that influence access to healthcare.Despite these well-described aims, the ideal implementation process for decolonising global health remains ill-defined. This ambiguity exists, in part, because partners face barriers to adopting a decolonised perspective. Such barriers include overemphasis on intercountry relationships, implicit hierarchies perpetuated by educational interventions and ethical dilemmas in global health work.In this article, we explore the historical entanglement of education, health and colonialism. We then use this history as context to identify barriers that arise when decolonising contemporary educational global health partnerships. Finally, we offer global health partners strategies to address these challenges.

Metabolic Toxification of 1,2-Unsaturated Pyrrolizidine Alkaloids Causes Human Hepatic Sinusoidal Obstruction Syndrome: The Update. Int J Mol Sci 2021; 22:ijms221910419. [PMID: 34638760 PMCID: PMC8508847 DOI: 10.3390/ijms221910419] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 09/09/2021] [Accepted: 09/14/2021] [Indexed: 12/15/2022] Open
Abstract
Saturated and unsaturated pyrrolizidine alkaloids (PAs) are present in more than 6000 plant species growing in countries all over the world. They have a typical heterocyclic structure in common, but differ in their potential toxicity, depending on the presence or absence of a double bond between C1 and C2. Fortunately, most plants contain saturated PAs without this double bond and are therefore not toxic for consumption by humans or animals. In a minority of plants, however, PAs with this double bond between C1 and C2 exhibit strong hepatotoxic, genotoxic, cytotoxic, neurotoxic, and tumorigenic potentials. If consumed in error and in large emouns, plants with 1,2-unsaturated PAs induce metabolic breaking-off of the double bonds of the unsaturated PAs, generating PA radicals that may trigger severe liver injury through a process involving microsomal P450 (CYP), with preference of its isoforms CYP 2A6, CYP 3A4, and CYP 3A5. This toxifying CYP-dependent conversion occurs primarily in the endoplasmic reticulum of the hepatocytes equivalent to the microsomal fraction. Toxified PAs injure the protein membranes of hepatocytes, and after passing their plasma membranes, more so the liver sinusoidal endothelial cells (LSECs), leading to life-threatening hepatic sinusoidal obstruction syndrome (HSOS). This injury is easily diagnosed by blood pyrrolizidine protein adducts, which are perfect diagnostic biomarkers, supporting causality evaluation using the updated RUCAM (Roussel Uclaf Causality Assessment Method). HSOS is clinically characterized by weight gain due to fluid accumulation (ascites, pleural effusion, and edema), and may lead to acute liver failure, liver transplantation, or death. In conclusion, plant-derived PAs with a double bond between C1 and C2 are potentially hepatotoxic after metabolic removal of the double bond, and may cause PA-HSOS with a potential lethal outcome, even if PA consumption is stopped.

Abstract
Introduction Sickle Cell Disease (SCD) is the leading genetic disease in sub-Saharan Africa and therefore remains a global public health threat. Use of complementary and alternative medicines (CAM) most especially herbal medicine (HM) in chronic diseases such as sickle cell disease has widely been reported in Africa where advanced technologies are greatly lacking. Despite a large presence of the sickle cell disease in Uganda, the extent to which herbal medicines are used in management of children with sickle cell disease has not been documented. This study purposed to determine the prevalence of herbal medicine (HM) use and associated factors among caregivers of children with SCD at Mulago National Referral Hospital. Methods a total of 384 child caretakers were interviewed in a descriptive cross-sectional quantitative study conducted at the Mulago Sickle cell clinic in March 2019. Enrolment was done consecutively and a structured interviewer administered questionnaire administered to collect data from the caretakers which was managed using SPSS version 23. Multivariate logistic regression was used to identify the factors associated with herbal medicine (HM) use. Factors with p-value <0.05 were regarded significant. Results the rate of herbal use was 77.6% (298 of 384 caregivers). At multivariate analysis, the odds of a caregiver who agreed that; HM cures symptoms faster than conventional medicine (CM) were 3 times those who disagreed with this statement (AOR =3.439, 95% CI: 1.447 - 8.176). The odds that a caregiver who agreed that HM has fewer side effects than CM were almost 4 times those that disagreed with this statement (AOR = 3.528, 95% CI: 1.917 -6.494). The odds that a caregiver who agreed that marketing HM through televisions adverts encourages HM use were 4 times those who disagreed with this statement (AOR = 4.185, 95% CI: 2.036 -8.603). Conclusion this study reports a high prevalence of HM use among caregivers of children with SCD at Mulago Hospital, in Uganda. The practice is significantly influenced by caretakers´ perception that HM cures symptoms faster than CM, has fewer side effects and that telemarketing has greatly facilitated its use over CM. More effort is therefore needed to encourage clinic attendances and CM use and limit the unfounded TV adverts on HM. There is also need for studies to identify the common HM used so that their efficacy and safety are well studied.

Abstract
Atopic dermatitis (AD) is a common inflammatory dermatologic disease clinically characterized by intense itch, recurrent eczematous lesions, and a chronic or relapsing disease course. Mild-to-moderate AD can be controlled by using moisturizers and topical immunomodulators such as topical corticosteroids and calcineurin inhibitors. If topical therapies fail, phototherapy and systemic immunosuppressant therapies, such as ciclosporin, methotrexate, and azathioprine, can be considered. However, relapse and side effects could still occur. The pathogenesis of AD involves epidermal barrier dysfunction, skin microbiome abnormalities, and cutaneous inflammation. Inflammatory mediators, such as interleukin (IL)-4, IL-13, IL-31, IL-33, IL-17, IL-23, and thymic stromal lymphopoietin, are involved in AD development. Therefore, a series of biological agents targeting these cytokines are promising approaches for treating AD. Dupilumab is the first biological agent approved for the treatment of AD in patients aged 6 years and older in the United States. Tralokinumab, lebrikizumab, and nemolizumab have also been confirmed to have significant efficacy against AD in phase III or IIb clinical trials. Also, fezakinumab was effective in severe AD patients in a phase IIa trial. However, phase II trials of ustekinumab, tezepelumab, etokimab, secukinumab, and omalizumab have failed to meet their primary endpoints. Phase II trials of GBR 830 and KHK 4083 are ongoing. In general, further studies are needed to explore new therapeutic targets and improve the efficacy of biological agents.

Abstract
Background Liver fibrosis is common among HIV-infected patients. Risk factors vary by location. Understanding this variation may inform prevention strategies. We compared the prevalence and correlates of liver fibrosis among HIV-infected patients attending care clinics in Uganda. Methods This was a cross-sectional study involving 2030 HIV-infected patients attending care clinics in urban and rural Uganda. Liver fibrosis was defined as liver stiffness measurement (LSM) >7.1 KPa. Proportions and correlates of liver fibrosis were assessed and compared using logistic regression stratified by gender and site. Results Prevalence of liver fibrosis was higher among participants in the rural clinic (15% vs 11%; P = .017). History of tobacco use (urban P = .022; rural P = .035) and serologic evidence of hepatitis C infection (HCV; urban P = .028; rural P = .03) was associated with liver fibrosis in all men. Elevated liver transaminases (urban P = .002; rural P = .028) and increasing age (urban P = .008; rural P = .052) were risk factors among all women. Tobacco use among women was only a risk factor in those attending the rural clinic (P = .003), and detectable HIV viral load (P = .002) for men in the urban clinic. Conclusions Liver fibrosis is prevalent among HIV-infected persons in Uganda. HIV viral suppression and avoiding tobacco may be strategies to prevent liver fibrosis and cancer risk.

[PMID: 32388879 PMCID: PMC8919060 DOI: 10.1111/jvh.13320] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2019] [Revised: 02/20/2020] [Accepted: 04/12/2020] [Indexed: 12/09/2022]
Abstract
Liver fibrosis may be assessed noninvasively with transient electrography (TE). Data on the performance of TE for detecting liver fibrosis in sub-Saharan Africa are limited. We evaluated the diagnostic accuracy of TE by performing liver biopsies on persons with liver fibrosis indicated by TE. We enrolled HIV-infected and HIV-uninfected participants with TE scores consistent with at least minimal disease (liver stiffness measurement [LSM]≥7.1 kPa). Biopsies were performed and staged using the Ishak scoring system. A concordant result was defined using accepted thresholds for significant fibrosis by TE (LSM ≥ 9.3 kPa) and liver biopsy (Ishak score ≥ 2). We used modified Poisson regression methods to quantify the univariate and adjusted prevalence risk ratios (PRR) of the association between covariates and the concordance status of TE and liver biopsy in defining the presence of liver fibrosis. Of 131 participants with valid liver biopsy and TE data, only 5 participants (3.8%) had Ishak score ≥ 2 of whom 4 had LSM ≥ 9.3 kPa (sensitivity = 80%); of the 126 (96.2%) with Ishak score < 2, 76 had LSM < 9.3 kPa (specificity = 61%). In multivariable analysis, discordance was associated with female gender (adjPRR = 1.80, 95%CI 1.1-2.9; P = .019), herbal medicine use (adjPRR 1.64, 95% CI = 1.0-2.5; P = .022), exposure to lake or river water (adjPRR 2.05, 95% CI = 1.1-3.7; P = .016), and current smoking (adjPRR 1.72, 95%CI 1.0-2.9; P = .045). These data suggest that TE among rural Ugandans has low specificity for detection of histologically confirmed liver fibrosis. Caution should be exercised when using this tool to confirm significant liver fibrosis.

Abstract
OBJECTIVES To examine the prevalence, determinants, safety perceptions, effectiveness and knowledge of herbal medicines (HMs) and reasons for non-hospital utilisation. DESIGN Cross-sectional study. SETTING Ekiti state, southwest Nigeria. PARTICIPANTS A representative sample (n=1600) of adults (18 years or above) currently living in Ekiti state, southwest Nigeria for at least 2 years, at the time of study. RESULTS The majority of the respondents (85% n=1265) have used HMs in the last 2 years. Across economic classes use, middle income (88.3%) was the highest (p<0.001), suggesting poverty is not a major factor, even with income inequality. Their use was the most common among respondents with a primary level of education (91.4%, p=0.001); and 100% use (p=0.009) of respondents practising African traditional religion; farmers and those 70 years or above. Our study also reveals more men (p<0.001) used HMs (89.9%) than women (78.6%) and effectiveness was a major reason for use (39.6%) followed by affordability (31.9%). Although the majority of the respondents (90%) knew the difference between certified and uncertified HMs, uncertified ones were the most commonly used (37.3%) in the population. CONCLUSION Although there is a cultural history of HM use within the study population, the choice of use was based on their effectiveness. Therefore, a scientifically valid analysis of this claim within the study population may help achieve a cheaper and affordable healthcare alternative which will be safe. This is important, considering that uncertified HMs were chosen over certified ones, even though a large majority of respondents were aware of differences and likely consequences. This study highlights the need for further investment by the government, individuals and corporate stakeholders in HM research and improvement of conventional healthcare system. This is in addition to public health awareness on the danger of use of uncertified herbal products.

Abstract
Primary liver cancer, particularly hepatocellular carcinoma (HCC), remains a major killer in sub-Saharan Africa. In this dreadful landscape, West and Central Africas are more particularly affected. However, a small country located on the equator, Gabon, is apparently not concerned by this adverse situation. Despite worrying prevalences of many bona fide risk factors of HCC, including high rates of chronic infections with hepatitis viruses and very high alcohol consumption, Gabon presents theoretically an amazingly low incidence of HCC when compared to other countries of the region. Reports from many places in the world have emphasized the widespread underreporting of HCC cases presumably attributable to the difficulties of proper diagnosis or to a lack of local cancer registry. In Gabon, the remarkably vivid tradition of religious initiation called Bwiti includes some therapeutic rituals exerted by healers or Ngangas. Those treatments are particularly popular in case of severe diseases generally associated with a supernatural etiology. In the present paper, we hypothesize that, in Gabon, the remarkably low incidence of HCC is primarily due to the diversion of patients from the modern medical system due to their preference for Ngangas. Promotion of a form of medical syncretism respecting both systems might be an efficient policy to increase the attractiveness of modern medicine and to ultimately promote public health in Gabon.

BMC Complement Med Ther 2020; 20:169. [PMID: 32493310 PMCID: PMC7268757 DOI: 10.1186/s12906-020-02959-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2019] [Accepted: 05/19/2020] [Indexed: 02/03/2023] Open
Abstract
Background There is some evidence that patients with liver diseases commonly use complementary and alternative therapies to address general and liver-disease specific health concerns. The purpose of this study was to assess and describe prevalence, patterns and related factors of herbal medicine use among adults diagnosed with viral and non-viral hepatitis in Kampala, Uganda. Methods A cross-sectional study was conducted on 310 adult patients attending the gastrointestinal clinic in Mulago hospital referral hospital in Kampala. Data on prevalence, types and reasons for herbal medicine use was collected using standardized questionnaires and focus group discussions. Modified Poisson regression analyses were used to examine factors related to use. Results Usage of various herbal remedies within 12 months prior to April 2018 was reported by 46.1% (143/310) of patients with 27.3% (39/143) of these reporting having used conventional and herbal therapies concurrently. Herbal remedies were used to treat various health conditions including hepatitis. Patients with hepatitis C virus infection (PRR = 1.16, p = 0.02) compared to those with hepatitis B virus infection, and those who believed that it was safe to use herbal and conventional therapies concurrently (PRR = 1.23, p = 0.008) had higher prevalence odds of herbal medicine use. Conversely, patients who had been newly diagnosed with hepatitis (PRR = 0.69, p = 0.03) compared to those who had been diagnosed more than one-year prior, had lower prevalence odds of herbal medicine use. Various types of local herbs were reported as most commonly used however most patients did not know the ingredients of commercially prepared herbal therapies. Conclusion A high prevalence of herbal medicine use was found among newly-diagnosed patients and patients with hepatitis C more likely to use herbal remedies after adjusting for other factors. Usage was influenced by the belief that herbal medicine is safe and effective. Health workers need to consistently elicit information about herbal remedy use. Research is needed on benefits, adverse effects and outcomes in patients who use herbal remedies to treat primary liver diseases in order to facilitate evidence of efficacy and product safety.

Traditional and Complementary Medicine Use Among Adult Cancer Patients Undergoing Conventional Treatment in Sub-Saharan Africa: A Scoping Review on the Use, Safety and Risks. Cancer Manag Res 2020; 12:3699-3712. [PMID: 32547206 PMCID: PMC7246319 DOI: 10.2147/cmar.s251975] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2020] [Accepted: 04/29/2020] [Indexed: 12/30/2022] Open
Abstract
Background Use of traditional and complementary medicine (T&CM) is very common among patients in sub-Saharan Africa (SSA). However, there are limited data on concurrent use of T&CM with conventional cancer therapies. In this scoping review, we sought to describe the (i) prevalence of use, (ii) types of medicine, (iii) reasons for taking T&CM, (iv) current knowledge on safety and risks, (v) characteristics of adult cancer patients who use T&CM, and (vi) perceived treatment outcomes among cancer patients undergoing conventional cancer treatment in SSA. Methods We conducted a systematic literature search for articles published in the English language in three scientific databases (PubMed, Embase and Web of Science). We used a scoping review approach to map relevant literature on T&CM use among cancer patients undergoing conventional cancer treatments. We assessed 96 articles based on titles and abstracts, and 23 articles based on full text. Twelve articles fulfilled preset eligibility criteria. Results More than half of the included articles were from only two countries in SSA: Nigeria and Uganda. Median prevalence of use of T&CM was 60.0% (range: 14.1-79.0%). Median percent disclosure of use of T&CM to attending healthcare professionals was low at 32% (range: 15.3-85.7%). The most common reasons for non-disclosure were: the doctor did not ask, the doctor would rebuke them for using T&CM, and the doctors do not know much about T&CM and so there is no need to share the issue of use with them. T&CM used by cancer patients included herbs, healing prayers and massage. Reported reasons for use of T&CM in 8 of 12 articles included the wish to get rid of cancer symptoms, especially pain, cure cancer, improve physical and psychological well-being, treat toxicity of conventional cancer therapies and improve immunity. There were limited data on safety and risk profiles of T&CM among cancer patients in SSA. Conclusion Use of traditional and complementary medicines is common among cancer patients undergoing conventional cancer treatments. Healthcare professionals caring for cancer patients ought to inquire and communicate effectively regarding the use of T&CM in order to minimize the risks of side effects from concurrent use of T&CM and biomedicines.

Abstract
AbstractOne of the major problems with the formulation of herbal medicines is the quality control of plant material to ensure its efficacy and safety. Quality control of medicinal plants requires analysis of many bioactive compounds present in the plant. C-alkylated flavonoids are an important bioactive subclass of flavonoids. A simple, rapid, sensitive and selective method is presented here for the quantification of bioactive C-alkylated flavonoids. This is the first quantitative method for analysis of C-alkylated flavonoids based on the multiple reaction monitoring (MRM) approach so far. This study focuses on method development for quantification of bioactive C-alkylated flavonoids. Quantification of a total of five C-alkylated flavonoids was done employing the MRM approach on an HPLC-QqQ-MS instrument. LODs and LOQs for quantified flavonoids were in the range of 0.41–1.32 and 1.23–3.96 ng/mL, respectively. Linear calibration curves between 25 and 1500 ng/mL were obtained with the regression coefficients of ≥0.996. Accuracy (% bias) and precision (% RSD) of the analyses were found to be less than 5%. Developed HPLC-ESI-MS/MS can be employed as a quality control method of plant raw materials.

Abstract
Background It is well established that Ebola Survivors experience a myriad of physical and psychological sequelae. However, little is known about how they seek care to address their health needs. Our study determines the current healthcare seeking behaviour among Ebola survivors and determines the prevalence, pattern of use and correlates of traditional and complementary medicine (T&CM) use among Ebola survivors in Sierra Leone. Methods We conducted a nationwide questionnaire survey among a cross-sectional sample of Ebola Survivors in Sierra Leone between January and August 2018. We employed descriptive statistics, chi-square test, Fisher exact two-tailed test and backward stepwise binary regression analysis for data analysis. A p-value less than 0.05 was considered statistically significant. Results Ebola Survivors who participated in our study (n = 358), visited a healthcare provider (n = 308, 86.0%), self-medicated with conventional medicines (n = 255, 71.2%) and visited a private pharmacy outlet (n = 141, 39.4%). Survivors also self-medicated with T&CM products (n = 107, 29.9%), concurrently self-medicated with conventional and T&CM products (n = 62, 17.3%), and visited a T&CM practitioner (n = 41, 11.5%). Almost half of (n = 163, 45.5%) Ebola survivors reported using T&CM treatments for post ebola related symptoms and non-Ebola related symptoms since their discharge from an Ebola treatment centre. Ebola survivors who considered their health to be fair or poor (AOR = 4.08; 95%CI: 2.22–7.50; p<0.01), presented with arthralgia (AOR = 2.52; 95%CI: 1.11–5.69, p = 0.026) and were discharged three years or less (AOR = 3.14; 95%CI: 1.13–8.73, p = 0.028) were more likely to use T&CM. Family (n = 101,62.0%) and friends (n = 38,23.3%) were the common sources of T&CM information. Abdominal pain (n = 49, 30.1%) followed by joint pain (n = 46, 28.2%) and back pain (n = 43, 26.4%) were the most cited post–Ebola indications for T&CM use. More than three-quarters of T&CM users (n = 135, 82.8%) failed to disclose their use of T&CM to their healthcare providers. Conclusion Ebola survivors in Sierra Leone employ a myriad of healthcare options including T&CM in addressing their healthcare needs. Researchers, health policy makers and healthcare providers should be aware of the substantial role of T&CM in the health seeking of survivors, and this topic that should be factored into future research, policy formulation and implementation as well as routine practice regarding Ebola survivors.

Abstract
Introduction: Drug-induced liver injury (DILI) has become the most frequent cause of acute liver failure in high-income countries. However, little is known about the determinants of DILI in sub-Saharan Africa (SSA), where the prescription of antimicrobials and the use of potentially hepatotoxic traditional medicine are common. Areas covered: Based on an extensive literature search, we summarize current data available on the epidemiology and risk factors of DILI in SSA. We discuss the most likely causes of DILI in the region, including antimicrobial therapies and traditional medicine. We also highlight research gaps as well as barriers to diagnosis and management of the condition, and explore ways to address these important challenges. Expert opinion: DILI is underestimated in SSA and several factors challenge its early diagnosis, including lack of information on the causes of DILI in the region, sub-optimal knowledge about the condition among clinicians, and structural difficulties faced by health care systems. In order to better prevent the occurrence of DILI and its complications, it is crucial to enhance awareness among health care providers and patients, adapt drug prescription habits and regulations, and improve current knowledge on the main risk factors for DILI, including host genetic and environmental determinants.

Medicinal plant species used by local communities around Queen Elizabeth National Park, Maramagambo Central Forest Reserve and Ihimbo Central Forest Reserve, South western Uganda. JOURNAL OF ETHNOPHARMACOLOGY 2019; 239:111926. [PMID: 31067488 DOI: 10.1016/j.jep.2019.111926] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2019] [Revised: 04/05/2019] [Accepted: 04/29/2019] [Indexed: 05/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The application of ethnobotanical indigenous knowledge is very important in improving primary healthcare systems among the local communities living around and within protected areas in South Western Uganda. In this area, there are biodiversity endowed Queen Elizabeth National Park (QENP), Maramagambo Central Forest Reserve (MCFR) and Ihimbo Central Forest Reserve (ICFR). Despite the rich floral diversity and cultural heritage, there is no published documentation on the use of medicinal plants in this area. This information can be used as a basis for the selection of medicinal plants for further phytochemical and pharmacological studies. STUDY AIM This study identified and documented the use of medicinal plants, plant parts used, and mode of preparation and administration by the local communities living around and within QENP, MCFR and ICFR. MATERIALS AND METHODS A cross-sectional study was used to collect data from 202 informants using semi-structured questionnaires, open interviews and field visits. Ethnobotanical data was analyzed using use reports (UR), frequency of citation (FC) and Informant Consensus Factor (FIC). The plants species were identified by botanists and voucher specimens were deposited. RESULTS A total of 302 medicinal plant species were mentioned by informants, out of which only 211 species belonging to 65 families and 165 genera were collected, identified and documented. The remaining 91 species were not available for collection and informants stated that they had become very rare within the study area. Herbs (35.8%) were the main source of herbal medicine. Leaves (60.4%) were the most commonly used plant parts used in the preparation of herbal remedies. Most of the medicinal plants were harvested from the wild, either growing in abundance (41%) or as rare species (21%). The most common mode of administration was oral, while other exceptional modes such as touching with bare hands and sweeping over the affected part were reported for the first time. The medicinal plant species were reported to treat 134 physical ailments, which were grouped into 16 ICPC-2 disease categories. Digestive disorders (854 UR) and general and unspecified disorders (507) scored the highest FIC value of 0.83. The highest number of medicinal plants (146 plant species) was used for treatment of digestive disorders. Among the species with higher use reports, Gouania longispicata had the highest frequency of citation (FC = 174) and was mentioned to be used to treat 41 physical ailments. The most important ailment treated by Gouania longispicata was allergy with 102 use reports. CONCLUSIONS A variety of medicinal plants are used by communities living near protected areas in South Western Uganda. Most species were used in the treatment of digestive disorders, followed by general and unspecified disorders. Much as allergy has not been identified as a major threat by the health sector in Uganda, the study found out that it is one of the prevalent ailments in the study area. While the therapeutic value of some of the documented medicinal plant species, especially those with higher frequency of citation have been scientifically validated, the efficacy and safety of other species with wide application need to be investigated. In this study, we recommend further scientific studies on Gouania longispicata to validate its wide usage in the study area.

Abstract
: Elevation of liver transaminases is common in patients infected with the HIV. Although this is usually an incidental finding during regular work-up, HIV-infected patients with transaminase elevations require additional visits for laboratory studies and clinical assessments, and often undergo interruptions and changes in antiretroviral therapy (ART). Alanine aminotransferase is present primarily in the liver, thus being a surrogate marker of hepatocellular injury. Aspartate aminotransferase is present in the liver and other organs, namely cardiac and skeletal muscle, kidney and brain. Serum levels of both liver transaminases predict liver-related mortality. Moreover, serum fibrosis biomarkers based on alanine aminotransferase and aspartate aminotransferase predict all-cause mortality. In a busy clinical setting, a diagnostic approach to elevated liver transaminases could be complicated given the frequency and nonspecificity of this finding. Indeed, HIV-infected individuals present multiple risk factors for liver damage and chronic elevation of transaminases, including coinfection with hepatitis B and C viruses, alcohol abuse, hepatotoxicity due to ART, HIV itself and frequent metabolic comorbidities leading to nonalcoholic fatty liver disease. This review provides an update on epidemiology of elevated liver transaminases, summarizes the main etiologic contributors and discusses the prognostic significance and a pragmatic approach to this frequent finding in the clinical practice of HIV medicine. With the aging of the HIV-infected population following the successful implementation of ART in Western countries, liver-related conditions are now a major comorbidity in this setting. As such, clinicians should be aware of the frequency, clinical significance and diagnostic approach to elevated liver transaminases.

Abstract
Background The WHO estimates that a considerable number of people in Sub-Saharan Africa (SSA) rely on traditional, complementary and alternative medicine (TCAM) to meet their primary healthcare needs, yet there remains a dearth of research evidence on the overall picture of TCAM utilisation in the region. Methods We conducted a literature search of original articles examining TCAM use in SSA between 1 January 2006 and 28 February 2017, employing Medline, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine Database, Scopus, ProQuest, PubMed, Embase and African Journals Online databases. A critical appraisal of relevant articles reporting a quantitative or mixed-method design was undertaken. Results Despite the heterogeneity and general low quality of the identified literature, the review highlights a relatively high use of TCAM alone or in combination with orthodox medicine, in both general population and in specific health conditions in SSA. TCAM users compared with non-TCAM users are more likely to be of low socioeconomic and educational status, while there were inconsistencies in age, sex, spatial location and religious affiliation between TCAM users and non-TCAM users. Most TCAM users (55.8%–100%) in SSA fail to disclose TCAM use to their healthcare providers, with the main reasons for non-disclosure being fear of receiving improper care, healthcare providers’ negative attitude and a lack of enquiry about TCAM use from healthcare providers. Conclusion TCAM use in SSA is significant, although most studies emerge from a few countries. Factors associated with TCAM use in SSA are similar to those observed in other regions, but further research may be required to further elucidate challenges and opportunities related to TCAM use specific to SSA.

Abstract
The last few decades have seen a rise in the use of herbal supplements, natural products, and traditional medicines. However, there are growing concerns related to the safety and toxicities of these medicines. These herbal medicines are associated with complications such as liver damage with a high incidence of mortalities and morbidities. Clinical manifestations range from asymptomatic cases with abnormal liver functions tests to sudden and severe liver failure necessitating liver transplantation. This work aimed to review the etiology, risk factors, diagnosis, clinical manifestations and selected clinical case reports of herbal hepatotoxicity in developing nations. PubMed and Google Scholar searches were undertaken to identify relevant literature. Furthermore, we scanned the reference lists of the primary and review articles to identify publications not retrieved by electronic searches. Little data exists on clinical cases of herb-induced liver injury in some developing countries such as Nigeria, as most incidences are either not reported to health care providers or reports from hospitals go unpublished. Studies in Nigeria have highlighted a possible correlation between use of herbs and liver disease. In Uganda, and association between the use of traditional herbal medicine with liver fibrosis in HIV-infected and non-HIV patients was demonstrated. Reports from China have revealed incidences of acute liver failure as a result of herbal medicine use. The actual incidence and prevalence of HILI in developing nations remain largely unknown due to both poor pharmacovigilance programs and non-application of emerging technologies. Improving education and public awareness of the potential risks of herbals and herbal products is desirable to ensure that suspected adverse effects are formally reported. There is need for stricter regulations and pre-clinical studies necessary for efficacy and safety.

Abstract
CONTEXT An ethnobotanical survey was completed in a remote village and surrounding country of Xinjiang, where most Uyghur medicinal plants could be collected. This work clarifies and increases ethnobotanical data. OBJECTIVES We surveyed and organized aromatic medicinal plants that are commonly used in clinical settings to provide a significant reference for studying new medical activities. MATERIALS AND METHODS In the survey, informants who have traditional knowledge on aromatic Uyghur medicinal plants were interviewed between March 2014 and September 2014. Aromatic medicinal plant species and pertinent information were collected. Some therapeutic methods and modes of preparation of traditional aromatic medicinal plants were found. RESULTS A total of 86 aromatic medicinal plant species belonging to 36 families were included in our study. We identified 34 plant species introduced from different regions such as Europe, India and Mediterranean areas. Fruits and whole plants were the most commonly used parts of plant, and most aromatic medicinal plants could be applied as medicine and food. We assigned the medicinal plants a use value (UV). Knowing the UV of species is useful in determining the use reliability and pharmacological features of related plants. CONCLUSIONS Xinjiang is an area in which indigenous aromatic medicinal plants are diversely used and has therefore established a sound dimensional medical healthcare treatment system. Some aromatic Uyghur medicinal plants are on the verge of extinction. Hence, further strategies for the conservation of these aromatic medicinal plants should be prioritized.

Abstract
OBJECTIVES To determine the incidence and risk factors of hospital-acquired suspected adverse drug reactions (ADRs) among Ugandan inpatients. We also constructed risk scores to predict and qualitatively assess for peculiarities between low-risk and high-risk ADR patients. METHODS Prospective cohort of consented adults admitted on medical and gynaecological wards of the 1790-bed Mulago National Referral Hospital. Hospital-acquired suspected ADRs were dichotomised as possible (possible/probable/definite) or not and probable (probable/definite) or not, using the Naranjo scale. Risk scores were generated from coefficients of ADR risk-factor logistic regression models. RESULTS The incidence of possible hospital-acquired suspected ADRs was 25% (194/762, 95% CI: 22% to 29%): 44% (85/194) experienced serious possible ADRs. The risk of probable ADRs was 11% (87/762, 95% CI 9% to 14%): 46% (40/87) had serious probable ADRs. Antibacterials-only (51/194), uterotonics-only (21/194), cardiovascular drugs-only (16/194), antimalarials-only (12/194) and analgesics-only (10/194) were the most frequently implicated. Treatment with six or more conventional medicines during hospitalisation (OR=2.31, 95% CI 1.29 to 4.15) and self-reported herbal medicine use during the 4 weeks preadmission (OR=1.96, 95% CI 1.22 to 3.13) were the risk factors for probable hospital-acquired ADRs. Risk factors for possible hospital-acquired ADRs were: treatment with six or more conventional medicines (OR=2.72, 95% CI 1.79 to 4.13), herbal medicine use during the 4 weeks preadmission (OR=1.68, 95% CI 1.16 to 2.43), prior 3 months hospitalisation (OR=1.57, 95% CI 1.09 to 2.26) and being on gynaecological ward (OR=2.16, 95% CI 1.36 to 3.44). More drug classes were implicated among high-risk ADR-patients, with cardiovascular drugs being the most frequently linked to possible ADRs. CONCLUSIONS The risk of hospital-acquired suspected ADRs was higher with preadmission herbal medicine use and treatment with six or more conventional medicines during hospitalisation. Our risk scores should be validated in large-scale studies and tested in routine clinical care.

Abstract
OBJECTIVE To describe liver disease epidemiology among HIV-infected individuals in Zambia. METHODS We recruited HIV-infected adults (≥18 years) at antiretroviral therapy initiation at two facilities in Lusaka. Using vibration controlled transient elastography, we assessed liver stiffness, a surrogate for fibrosis/cirrhosis, and analysed liver stiffness measurements (LSM) according to established thresholds (>7.0 kPa for significant fibrosis and >11.0 kPa for cirrhosis). All participants underwent standardised screening for potential causes of liver disease including chronic hepatitis B (HBV) and C virus co-infection, herbal medicine, and alcohol use. We used multivariable logistic regression to identify factors associated with elevated liver stiffness. RESULTS Among 798 HIV-infected patients, 651 had a valid LSM (median age, 34 years; 53% female). HBV co-infection (12%) and alcohol use disorders (41%) were common and hepatitis C virus co-infection (<1%) was rare. According to LSM, 75 (12%) had significant fibrosis and 13 (2%) had cirrhosis. In multivariable analysis, HBV co-infection as well as male sex, increased age and WHO clinical stage 3 or 4 were independently associated with LSM >7.0 kPa (all P < 0.05). HBV co-infection was the only independent risk factor for LSM >11.0 kPa. Among HIV-HBV patients, those with elevated ALT and HBV viral load were more likely to have significant liver fibrosis than patients with normal markers of HBV activity. CONCLUSIONS HBV co-infection was the most important risk factor for liver fibrosis and cirrhosis and should be diagnosed early in HIV care to optimise treatment outcomes.

Abstract
Background Prisoners represent a vulnerable population for blood-borne and sexually transmitted infections which can potentially lead to liver fibrosis and ultimately cirrhosis. However, little is known about the prevalence of liver fibrosis and associated risk factors among inmates in sub-Saharan Africa. Methods Screening of liver fibrosis was undertaken in a randomly selected sample of male inmates incarcerated in Lome, Togo and in Dakar, Senegal using transient elastography. A liver stiffness measurement ≥9.5 KPa was retained to define the presence of a severe liver fibrosis. All included inmates were also screened for HIV, Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) infection. Substances abuse including alcohol, tobacco and cannabis use were assessed during face-to-face interviews. Odds Ratio (OR) estimates were computed with their 95 % Confidence Interval (CI) to identify factors associated with severe liver fibrosis. Results Overall, 680 inmates were included with a median age of 30 years [interquartile range: 24–35]. The prevalence of severe fibrosis was 3.1 % (4.9 % in Lome and 1.2 % in Dakar). Infections with HIV, HBV and HCV were identified in 2.6 %, 12.5 % and 0.5 % of inmates, respectively. Factors associated with a severe liver fibrosis were HIV infection (OR = 7.6; CI 1.8–32.1), HBV infection (OR = 4.8; CI 1.8–12.8), HCV infection (OR = 52.6; CI 4.1–673.8), use of traditional medicines (OR = 3.7; CI 1.4–10.1) and being incarcerated in Lome (OR = 3.3; CI 1.1–9.8) compared to Dakar. Conclusions HIV infection and viral hepatitis infections were identified as important and independent determinants of severe liver fibrosis. While access to active antiviral therapies against HIV and viral hepatitis expands in Africa, adapted strategies for the monitoring of liver disease need to be explored, especially in vulnerable populations such as inmates.

Abstract
SETTING National tuberculosis control programme, Vanuatu. OBJECTIVE To assess tuberculosis (TB) trends, characterise sputum smear-positive patients with non-conversion at 2 months and assess their treatment outcomes. DESIGN Evaluation of programme data over a 9-year period (2004-2012), comparing 2-month sputum non-converters (delayed converters) with sputum smear converters diagnosed in 2011 and 2012. RESULTS Annual TB case numbers were similar over the study period, with an average TB notification rate of 58 per 100 000 population. Of 417 sputum smear-positive cases, 74 (18%) were delayed converters. Delayed converters were more likely than converters (88% vs. 79%) to have had high pre-treatment sputum smear grades (OR 2.5, 95%CI 0.97-6.45). Among delayed converters, treatment adherence was high (99% good adherence), outcomes were generally good (90% treatment success, 85% cure, 4% treatment failure) and no drug resistance was detected. Deaths were unexpectedly common among converters (11/80, 14%), with significantly more deaths in Tafea than in Shefa Province (7/58 vs. 2/80, OR 5.35, 95%CI 1.07-26.79). Tafea Province also had the greatest number of delayed converters (30/74, 40.5%) and the highest TB incidence rate. CONCLUSION Delayed sputum conversion was relatively uncommon, and was not associated with adverse outcomes or drug resistance. Regional differences require further investigation to better understand local factors that may compromise patient management.

Abstract
BACKGROUND & AIMS We investigated the association between significant liver fibrosis, determined by AST-to-platelet ratio index (APRI), and all-cause mortality among HIV-infected patients prescribed antiretroviral therapy (ART) in Zambia. METHODS Among HIV-infected adults who initiated ART, we categorized baseline APRI scores according to established thresholds for significant hepatic fibrosis (APRI ≥1.5) and cirrhosis (APRI ≥2.0). Using multivariable logistic regression we identified risk factors for elevated APRI including demographic characteristics, body mass index (BMI), HIV clinical and immunological status, and tuberculosis. In the subset tested for hepatitis B surface antigen (HBsAg), we investigated the association of hepatitis B virus co-infection with APRI score. Using Kaplan-Meier analysis and Cox proportional hazards regression we determined the association of elevated APRI with death during ART. RESULTS Among 20 308 adults in the analysis cohort, 1027 (5.1%) had significant liver fibrosis at ART initiation including 616 (3.0%) with cirrhosis. Risk factors for significant fibrosis or cirrhosis included male sex, BMI <18, WHO clinical stage 3 or 4, CD4(+) count <200 cells/mm(3) , and tuberculosis. Among the 237 (1.2%) who were tested, HBsAg-positive patients had four times the odds (adjusted odds ratio, 4.15; 95% CI, 1.71-10.04) of significant fibrosis compared HBsAg-negatives. Both significant fibrosis (adjusted hazard ratio 1.41, 95% CI, 1.21-1.64) and cirrhosis (adjusted hazard ratio 1.57, 95% CI, 1.31-1.89) were associated with increased all-cause mortality. CONCLUSION Liver fibrosis may be a risk factor for mortality during ART among HIV-infected individuals in Africa. APRI is an inexpensive and potentially useful test for liver fibrosis in resource-constrained settings.

Oh SJ, Cho JH, Son CG. Systematic review of the incidence of herbal drug-induced liver injury in Korea. JOURNAL OF ETHNOPHARMACOLOGY 2015; 159:253-256. [PMID: 25460587 DOI: 10.1016/j.jep.2014.11.027] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2014] [Revised: 10/16/2014] [Accepted: 11/15/2014] [Indexed: 06/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Herbal drugs have been generally believed to be safe, based on the natural sources and long clinical experience. With the increasing use of herbal medicine worldwide, the potential toxicity of herbal drugs, especially drug-induced liver injury (DILI), frequently becomes a medical issue. This study was aimed to estimate the incidence of DILI following herbal drug consumption in Korea METHODS AND MATERIALS A literature search for herbal DILI in eight databases, including PubMed, Medline, the Cochrane Library, EMBASE, and four Korean electronic databases. RESULTS Six studies (three prospective and three retrospective) met the necessary criteria for assessment of the risk of DILI following herbal medicine exposure. The total number of participants in the six studies was 1699 (756 males and 943 females), and the incidence of herbal DILI varied from 0 to 1.92 among them. Total incidence of herbal DILI was 0.71% (12 patients with herbal DILI), and it was significantly higher in male (1.32%) than female (0.21%) respectively (p<0.01). All of the patients that experienced DILI concomitantly ingested herbal medicine and conventional drugs. CONCLUSIONS This result showed the comprehensive data indicating the incident risk of hepatotoxicity in patients using herbal drugs in Korea, and presented the possibility of increased risk for the DILI by concurrent administration of herbal and conventional medicines.

Noncommunicable diseases in HIV infection in low- and middle-income countries: gastrointestinal, hepatic, and nutritional aspects. J Acquir Immune Defic Syndr 2014; 67 Suppl 1:S79-86. [PMID: 25117963 DOI: 10.1097/qai.0000000000000260] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/17/2022]
Abstract
The purpose of this review was to outline the interaction between HIV and noncommunicable diseases affecting the gastrointestinal (GI) tract, liver, and nutritional disorders in low- and middle-income countries (LMICs), and to identify research priorities. Noncommunicable GI tract disorders are only moderately influenced by HIV, and peptic ulceration is actually less common. However, the impact of HIV on GI cancers needs further investigation. HIV interacts strongly with environmental enteropathy, exacerbating malabsorption of nutrients and drugs. HIV has 2 major effects on noncommunicable liver disease: drug-induced liver injury and nonalcoholic fatty liver disease (particularly in persons of African genetic descent). The effect of HIV on nutrition was one of the first markers of the epidemic in the 1980s, and HIV continues to have major nutritional consequences. Childhood malnutrition and HIV frequently coexist in some regions, for example, southern Africa, resulting in powerful negative interactions with poorer responses to standard nutritional rehabilitation. HIV and nutritional care need to be better integrated, but many questions on how best to do this remain unanswered. Across the spectrum of GI, hepatic, and nutritional disorders in HIV infection, there is increasing evidence that the microbiome may play an important role in disease pathogenesis, but work in this area, especially in low- and middle-income countries, is in its infancy.

Abstract
This study's objective was to describe awareness of, access to, belief in, and utilization of the healing tea Kikombe cha babu and other alternative treatments for HIV in Tanzania. Associations with HIV testing, treatment, and prevention behaviors are also explored. A survey with questions about alternative medicine was administered to a sample in Tanzania using a stratified, multistage random selection method. Adults were interviewed face-to-face. Items concerning alternative HIV treatments addressed awareness, access, beliefs, and treatment-seeking behaviors. Questions about HIV prevention and treatment were also asked. Results showed participants indicated a high awareness of alternative treatments available in Tanzania, with 95.3% of 2313 adults having heard of these treatments. Of those, 6.0% had actually sought the treatment, and 46.8% had an acquaintance seek it. However, 81.0% indicated these treatments were not easily accessible. There is a high level of belief in the ability of these alternative treatments to cure HIV, with 44.0% of people who had heard of these treatments indicating they believe such treatments can cure HIV. Additionally, many people indicated having these alternative treatments available would result in decreased condom use (15.6%), no need to use condoms (94.9%), and no need to take antiretroviral therapy (81.7%). However, 57.4% indicated they would be more likely to get tested for HIV if alternative treatments were available. Belief in the ability of alternative treatments to cure HIV in Tanzania is high and should be further explored due to its implications for potentially sidelining HIV prevention and treatment initiatives.

Ekor M. The growing use of herbal medicines: issues relating to adverse reactions and challenges in monitoring safety. Front Pharmacol 2014; 4:177. [PMID: 24454289 PMCID: PMC3887317 DOI: 10.3389/fphar.2013.00177] [Citation(s) in RCA: 1215] [Impact Index Per Article: 121.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2013] [Accepted: 12/23/2013] [Indexed: 12/11/2022] Open
Abstract
The use of herbal medicinal products and supplements has increased tremendously over the past three decades with not less than 80% of people worldwide relying on them for some part of primary healthcare. Although therapies involving these agents have shown promising potential with the efficacy of a good number of herbal products clearly established, many of them remain untested and their use are either poorly monitored or not even monitored at all. The consequence of this is an inadequate knowledge of their mode of action, potential adverse reactions, contraindications, and interactions with existing orthodox pharmaceuticals and functional foods to promote both safe and rational use of these agents. Since safety continues to be a major issue with the use of herbal remedies, it becomes imperative, therefore, that relevant regulatory authorities put in place appropriate measures to protect public health by ensuring that all herbal medicines are safe and of suitable quality. This review discusses toxicity-related issues and major safety concerns arising from the use of herbal medicinal products and also highlights some important challenges associated with effective monitoring of their safety.
