RESUMO

Despite high incidence rates and severe complications, the management of xerostomia lacks clinical guidelines. The aim of this overview was to summarize the clinical experience derived from the last 10 years of treatments and prevention using systemic compounds. Results showed that the cytoprotective drug amifostine, and its antioxidant agents, are the most discussed as preventive agents of xerostomia in head and neck cancer (HNC) patients. In the presence of the disease, the pharmacological treatments have been mainly directed to stimulate secretion of the damaged salivary glands, or to counteract a decreased capacity of the antioxidant system, in view of an increasing of reactive oxygen species (ROS). However, the data demonstrated low ability of the drugs, together with a great number of side effects, which strongly limit their use. Concerning traditional medicine (TM), valid clinical trials are so limited that neither the efficacy nor the absence of interferences to concomitant chemical therapies can be validated. Consequently, the management of xerostomia and its devastating complications remain a very significant void in daily clinical practice.

RESUMO

A middle-aged male who suffered from heartburn ingested 1 tablespoon of bicarbonate dissolved in water to relieve symptoms. Minutes afterwards he debuted with severe abdominal pain. Upon arrival at hospital 35 minutes later he was septic with peritonitis. Surgery without preoperative radiology was contemplated. However, a promptly available CT-scan interpreted by a radiologist revealed small amounts of pneumoperitoneum. During laparotomy findings were minor and the anticipated perforation could not be localized. However, after extensive air insufflation with a gastroscope a perforation below the gastroesophageal junction was detected.  This case illustrates how a seemingly harmless home remedy resulted in a life-threatening condition. During night-time in Sweden, primary radiological services are often only offered digitally by remote radiologists. Such a remote organization at our hospital might have resulted in omitting CT to avoid delay, but with an increased risk of misdiagnosing our patient.

RESUMO

BACKGROUND: Use of traditional medicine (TM) is widespread in sub-Saharan Africa as a treatment option for a wide range of disease. We aimed to describe main characteristics of TM users and estimate the association of TM use with control of hypertension. METHODS: We used data on 2128 hypertensive patients of a cross-sectional study (convenience sampling), who attended cardiology departments of 12 sub-Saharan African countries (Benin, Cameroon, Congo, Democratic Republic of the Congo, Gabon, Guinea, Côte d'Ivoire, Mauritania, Mozambique, Niger, Senegal, Togo). To model association of TM use with odds of uncontrolled, severe and complicated hypertension, we used multivariable mixed logistic regressions, and to model the association with blood pressure (systolic (SBP) and diastolic (DBP)) we used mixed linear models. All models were adjusted for age, sex, wealth, adherence to hypertension conventional treatment and country (random effect). RESULTS: A total of 512 (24%) participants reported using TM, varying across countries from 10% in the Congo to 48% in Guinea. TM users were more likely to be men, living in rural area, poorly adhere to prescribed medication (frequently due to its cost). Use of TM was associated with a 3.87 (95% CI 1.52 to 6.22)/1.75 (0.34 to 3.16) mm Hg higher SBP/DBP compared with no use; and with greater odds of severe hypertension (OR=1.34; 95% CI 1.04 to 1.74) and of any hypertension complication (OR=1.27; 95% CI 1.01 to 1.60), mainly driven by renal complication (OR=1.57; 95% CI 1.07 to 2.29) after adjustment for measured confounders. CONCLUSIONS: The use of TM was associated with higher blood pressure, more severe hypertension and more complications in Sub-Saharan African countries. The widespread use of TM needs to be acknowledged and worked out to integrate TM safely within the conventional healthcare.

RESUMO

The use of phytochemicals is gaining interest for the treatment of metabolic syndromes over the synthetic formulation of drugs. Senna is evolving as one of the important plants which have been vastly studied for its beneficial effects. Various parts of Senna species including the root, stem, leaves, and flower are found rich in numerous phytochemicals. In vitro, in vivo, and clinical experiments established that extracts from Senna plants have diverse beneficial effects by acting as a strong antioxidant and antimicrobial agent. In this review, Senna genus is comprehensively discussed in terms of its botanical characteristics, traditional use, geographic presence, and phytochemical profile. The bioactive compound richness contributes to the biological activity of Senna plant extracts. The review emphasizes on the in vivo and in vitro antioxidant and anti-infectious properties of the Senna plant. Preclinical studies confirmed the beneficial effects of the Senna plant extracts and its bioactive components in regard to the health-promoting activities. The safety, side effects, and therapeutic limitations of the Senna plant are also discussed in this review. Additional research is necessary to utilize the phenolic compounds towards its use as an alternative to pharmacological treatments and even as an ingredient in functional foods.

RESUMO

OBJECTIVE: Mangifera indica Linn, Bridelia ferruginea Benth, and Alstonia boonei De Wild are three plants commonly used in the traditional treatment of urinary tract infections in Benin. This study sets out to assess the cytotoxic and teratogenic effects of extracts of these plants on Artemia salina larvae and hen embryos. METHODS AND RESULTS: The aqueous and ethanolic extracts were obtained by maceration of the powders in solvents. Larval cytotoxicity was performed on Artemia salina larvae. The teratogenic effect of these plants was evaluated on chick embryos at 100 mg/kg and 300 mg/kg. The extracts were injected on the 7th and 14th days of incubation. The quality of the hatched chicks was evaluated by the Tona score followed by the hematological and the biochemical parameter assays. The extracts did not show cytotoxicity on the larvae. The eggs treated with plant extracts at 300 mg/kg significantly lowered the hatchability rate, except for the Mangifera indica Linn. The chicks obtained were all at the very good quality. Then, no significant variation was observed between hematological parameters except white blood cells. For the biochemical parameters, only ASAT showed some significant variations for a few extracts. It would be important to assess the genotoxicity of the plant extracts to determine more broader toxicity. These data justify the use of these medicinal plants in traditional Beninese medicine and constitute in fact a source of production of anti-infectious drugs.

RESUMO

Acute gastroenteritis (AGE) is the highest cause of mortality worldwide in children under the age of 5 years, with the highest mortalities occurring in low-to-middle income countries. Treatment can involve use of unregulated herbal medication and antibiotics. A cross sectional study was carried out to investigate the use of antibiotics and traditional herbal medications in the management of AGE among Yòrùbá-speaking communities in Kwara State, Nigeria. Our findings suggest habitual use of antibiotics (54.6%) and herbal medication (42.5%) in the management of AGE with high levels of self-prescription of antibiotics (21.7%) and herbal medications (36.2%) within the community. Ethanolic extracts of selected herbal plants reported (i.e. Aristolochia ringens, Azadirachta indica, Chromolaena odorata, Etanda Africana, Ficus capensis, Ficus vogelii, Mangifera indica, Momordica charantia, Ocimum gratisimum, Senna alata, Sorghum bicolor and Vernonia amygdalina) were investigated for antibacterial properties, using bacteria known to be causative agents of AGE. Our findings showed that, with exception of Ficus vogelii, which enhanced bacterial growth, the plant extracts reported all showed some antibacterial activity. We further discuss our findings within a regulatory context, with the aim to guide the use of traditional and herbal medication in low-to medium income countries (LMICs) and reduce the potential risks associated with the development of antimicrobial resistance.

RESUMO

Acute interstitial nephritis can result due to exposure to any medication, toxins, infections or malignancy. In the midst of this Coronavirus (COVID-19) pandemic, there has been a race for finding remedies to prevent the spread of and control the complications due to Severe Acute Respiratory Syndrome Coronavirus 2. Certain Indian medicinal herb concoctions like kabasura kudineer and nilavembu kudineer are being widely publicized to boost immunity and reduce the risk of developing COVID-19. Little knowledge exists about the adverse effects of these herbal remedies. We report two patients who presented to us with vague complaints following the ingestion of kabasura kudineer and we diagnosed them with acute tubulointerstitial nephritis (ATIN). The temporal relationship of ingestion of these remedies to the development of ATIN calls for vigilance and caution with regular monitoring of renal functions especially in those with chronic kidney disease.

RESUMO

Traditional medicine utilisation during antenatal care has been on the increase in several countries. Therefore, addressing and reinforcing the Sustainable Development Goal of maternal mortality reduction, there is a need to take traditional medicine utilisation during pregnancy into consideration. This paper explores traditional medicine utilisation during antenatal care among women in Bulilima District of Plumtree in Zimbabwe. A cross-sectional survey was conducted on 177 randomly selected women using a semi-structured questionnaire. Fisher's Exact Test, Odds Ratios, and Multiple Logistic Regression were utilised to determine any associations between different demographic characteristics and traditional medicine utilisation patterns using STATA SE Version 13. The prevalence of Traditional Medicine utilisation among pregnant women was estimated to be 28%. Most traditional remedies were used in the third trimester to quicken delivery. The majority of women used holy water and unknown Traditional Medicine during pregnancy. There was a strong association between age and Traditional Medicine utilisation as older women are 13 times more likely to use Traditional Medicine than younger ones. Women use traditional medicine for different purposes during pregnancy, and older women's likelihood to use Traditional Medicine is higher than their counterparts. The traditional system plays an essential role in antenatal care; therefore, there is a need to conduct further studies on the efficacy and safety of utilising Traditional Medicines.

RESUMO

BACKGROUND: Symptom resolution is the most common clinical practice during assessment and evaluation of helicobacter pylori infected patients after employing eradication therapy. OBJECTIVE: Prediction of eradication of H. pylori with symptom resolution and assess factors affecting symptom resolution. METHOD: Facility based follow up study was done on consented H. pylori positive adult patients who received standard triple therapy consisting of a proton pump inhibitor, amoxicillin, and clarithromycin from May 2016 to April 2018 at Bahir Dar city in Ethiopia. Sociodemographic and clinical data was collected before and after eradication therapy by using pre-developed structured questionnaire. Both positive and negative predictive values were calculated. SPSS version 23 was used to conduct bivariate and backward stepwise multivariate logistic regression to analyze data. P-value < 0.05 at 95%CI was considered as significant. RESULT: The study involved a total of 421 patients who completed follow up. Patients' mean age and body weight (±SD) were 30.63 (± 10.74) years and 56.71 (± 10.19) kg, respectively. Complete symptom resolution was achieved in 84.3% of the patients and eradication of H. pylori was successful in 90% of patients. Positive predictive value of complete symptom resolution for H. pylori eradication was 98.9% (351/355) and whereas negative predictive value was 57.6%(38/66). Factors associated with complete symptom resolution were regimen completion (AOR: 2.77 95%CI (1.12-6.86), p = 0.028) and no use of traditional homemade supplements prepared from Fenugreek or Flaxseed (AOR: 2.09 95%CI (1.22-3.58), p = 0.007). CONCLUSION: Complete symptom resolution is a powerful predictor of success of H. pylori eradication and can be used to assess H. pylori status after eradication therapy. Assessment of complete symptom resolution should consider regimen completion and traditional practice of using homemade supplements prepared from Fenugreek or Flaxseed.

RESUMO

This review focuses on four new product categories of food supplements: pre-workout, fat burner/thermogenic, brain/cognitive booster, and hormone/testosterone booster. Many food supplements have been shown to be contaminated with unauthorized substances. In some cases, the ingredients in the new categories of dietary supplements were medicinal products or new synthetic compounds added without performing clinical trials. Some of the new ingredients in dietary supplements are plant materials that are registered in the pharmacopoeia as herbal medicines. In other cases, dietary supplements may contain plant materials that have no history of human use and are often used as materials to 'camouflage' stimulants. In the European Union, new ingredients of dietary supplements, according to European Food Safety Authority or unauthorized novel food. Furthermore, selected ingredients in dietary supplements may be prohibited in sports and are recognized as doping agents by World Anti-Doping Agency.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: The increasing national prevalence of diabetes mellitus (DM) and its complications have overstretched the health care system in Tanzania and influenced patients to use herbal medicines as alternative therapeutic strategies. Therefore, an urgent need exists to validate the safety and efficacy of plants used locally. AIM OF THE STUDY: To identify plants used for the management of DM in Tanzania and analyses their pharmacological, phytochemistry, and safety evidence with a special focus on the mechanism of action. METHODS: Researchers searched Medline, web of science, and Scopus for published articles. Also, specialized herbarium documents of Muhimbili Institute of traditional medicine were reviewed. Articles were assessed for relevance, quality, and taxonomical accuracy before being critically reviewed. RESULTS: We identified 62 plant species used locally for DM management. Moringa oleifera Lam. and Cymbopogon citratus (D.C) stapf were the most mentioned. Fifty-four phytochemicals from 13 species had DM activities. These were mainly; polyphenolics, phytosterols, and triterpenoids. Extracts, fractions, and pure compounds from 18 species had in vitro antidiabetic activities of which 14 had α-glucosidase and α-amylase inhibition effects. The most studied -Momordica charantia L. increased; glucose uptake and adiponectin release in 3T3-L1 adipocytes, insulin secretion, insulin receptor substrate-1 (IRS-1), GLUT-4 translocation, and GLP-1 secretion; and inhibited protein tyrosine phosphatase 1 B (PTP1B). Preclinical studies reported 30 species that lower plasma glucose with molecular targets in the liver, skeletal muscles, adipose tissues, pancreases, and stomach. While three species; Aspilia mossambiscensis (Oliv.) Willd, Caesalpinia bonduc (L.) Roxb, and Phyllanthus amarus Schumach. & Thonn. had mild toxicity in animals, 33 had no report of their efficacy in DM management or toxicity. CONCLUSION: Local communities in Tanzania use herbal medicine for the management of DM. However, only a fraction of such species has scientific evidence. A. mossambiscensis, C. bonduc., and P. amarus had mild toxicity in animals. Together, our findings call for future researches to focus on in vitro, in vivo, and phytochemical investigation of plant species for which their use in DM among the local communities in Tanzania have not been validated.

RESUMO

The popularity of natural medicine is growing worldwide. Unlike conventional licensed medicines, herbal medicine practices are usually not supported by effectiveness, efficacy, or safety studies, which raise concerns about potential risks involved in their usage, particularly in high-risk patients such as pregnant women where teratogenicity is a concern. Despite a lack of science-based evidence, the use of herbal products for the management of pregnancy-associated challenges is common, due to the common notion that they are free of toxic effects and adverse reactions because they are "natural." The lack of concern about utilizing herbal remedies during pregnancy is strengthened by the lack of regulation in most countries for their marketing. However, plant-based remedies are not free of adverse reactions. Medicinal plants and herbal remedies contain substances that can be toxic to the human body and the fetus. Potential effects of indiscriminate use of medicinal plants are embryotoxicity, teratogenic, and abortifacient effects. Some plant constituents can cross the placenta and reach the fetus. Phytochemicals and their metabolites are known to induce stimulation of uterine contraction and hormone imbalance that could result in abortion. The alterations to the hormonal profile can affect conception, induce teratogenic activity, and halt the pregnancy or produce a congenital malformation. Due to the wide range of modes of action of phytochemicals, some medicinal plants may be safe to use during certain trimesters of pregnancy and harmful at other stages. This manuscript reviews available scientific information concerning potential health hazards associated with the consumption of herbal medicines during pregnancy, highlighting those herbs that should be avoided due to their potential abortifacient and/or teratogenic activity. We focused on plants that were tested by preclinical studies, and studies of these plants are summarized. Common therapeutic use of these herbs, estimated effects, toxicological effects, and animal studies of these plants is summarized. The literature reviewed suggests that consumption of the following medicinal plants should be avoided during pregnancy: Abrus precatorius, Achyranthes aspera, Ailanthus excelsa, Aloe vera, Aristolochia indica, Areca catechu, Bambusa vulgaris, Cassia occidentalis, Cicer arietinum, Cimicifuga racemose, Dolichandrone falcate, Ginkgo biloba, Hydrastis canadensis, Indigofera trifoliate, Lavandula latifolia, Maytenus ilicifolia, Momordica cymbalaria, Moringa oleifera, Musa rosacea, Oxalis corniculate, Phytolacca dodecandra, Plumeria rubra, Ricinus communis, Ruta graveolens, Stachys lavandulifolia, Senna alata, Trigonella foenum-graecum, Vitus agnus-castus, and Valeriana officinalis.
