Effects of Honey on Oral Mucositis among Pediatric Cancer Patients Undergoing Chemo/Radiotherapy Treatment at King Abdulaziz University Hospital in Jeddah, Kingdom of Saudi Arabia

Prevention and Treatment of Oral Mucositis in Pediatric Patients: Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND/AIM

Oral mucositis (OM) is a common and serious side effect of cancer treatment. The incidence of chemotherapy-induced OM in pediatric patients can reach up to 91.5% and has a major impact on patients' quality of life. The aim of the study was to assess the efficacy of current interventions and agents for the management of OM in children undergoing chemo/radiotherapy or hematopoietic stem cell transplantation (HSCT).

MATERIALS AND METHODS

A systematic search of randomized controlled trials (RCTs) was conducted in the MEDLINE and Scopus databases from January 2000 until March 2023. Thirty-four randomized studies meeting the inclusion criteria were identified and five RCTs investigating the efficacy of Low Level Laser Therapy (LLLT) intervention or the agent honey were included in the meta-analysis.

RESULTS

The meta-analysis of two RCTs indicated that topical application of honey on oral mucosa was effective in shortening the mean duration of hospital stay in children with severe OM (MD=-4.33, p=0.002). However, LLLT was not found to be effective for the prevention or treatment of OM grade ≥II (RR=0.99, p=0.99). Moreover, the therapeutic application of LLLT did not show significant benefit for lower risk of OM grade ≥II (RR=0.48, p=0.58).

CONCLUSION

Various interventions and agents were examined in the present study for the management of OM. Honey could be a promising candidate for the treatment of OM in pediatric patients. Further high-quality RCTs are required to enhance our findings.

Evaluation of health-related quality of life and its domains in pediatric patients with cancer

BACKGROUND

Health-related quality of life has emerged as a significant component in pediatric oncology research during the last several decades. Measures of health-related quality of life provide a thorough assessment of the child's response to medical therapy, disease course, and adjustment outcomes in the context of pediatric oncology.

METHODS

The aim of the present study was to assess the cancer-specific health-related quality of life in cancer pediatric patients and to evaluate the contribution of its domains and some of the anthropometric, sociodemographic, and treatment-related variables on the overall quality of life, by using the PedsQL™ 3.0 Cancer Module.

RESULTS

The study included 110 cases. The mean value of the PedsQL™ 3.0 Cancer Module score was 49.3 ± 12.0. The lowest mean score of quality of life was for the "procedure anxiety" (8.7 ± 23.9), followed by the "worry" domains (16.6 ± 28.5). Higher "frequency of hospital visits" was associated with increased feeling of pain and treatment anxiety yet decrease in suffering from nausea and vice versa. The longer period of hospital admission for more than half of the recommended treatment period was associated with reduced pain suffering on the expense of increase in feeling of worry as well as communication problems. The perceived physical appearance was better among those patients who spent a treatment period for 3-6 months when compared to those who spent a treatment period less than 3 months or more than 6 months. There was a highly significant association between all the eight-cancer-specific quality-of-life domains except the pain domain- and the overall quality-of-life log scores. Nausea problem followed by worry and cognitive problems was the most effective domains on the overall quality-of-life score.

CONCLUSION

Cancer pediatric patients suffered low quality of life especially for anxiety procedure and worry domains with special consideration for the impact of nausea, worry, and cognitive problems on their perception of quality of life.

Integrative Medicine for Pain Management in Oncology: Society for Integrative Oncology-ASCO Guideline

PURPOSE

The aim of this joint guideline is to provide evidence-based recommendations to practicing physicians and other health care providers on integrative approaches to managing pain in patients with cancer.

METHODS

The Society for Integrative Oncology and ASCO convened an expert panel of integrative oncology, medical oncology, radiation oncology, surgical oncology, palliative oncology, social sciences, mind-body medicine, nursing, and patient advocacy representatives. The literature search included systematic reviews, meta-analyses, and randomized controlled trials published from 1990 through 2021. Outcomes of interest included pain intensity, symptom relief, and adverse events. Expert panel members used this evidence and informal consensus to develop evidence-based guideline recommendations.

RESULTS

The literature search identified 227 relevant studies to inform the evidence base for this guideline.

RECOMMENDATIONS

Among adult patients, acupuncture should be recommended for aromatase inhibitor-related joint pain. Acupuncture or reflexology or acupressure may be recommended for general cancer pain or musculoskeletal pain. Hypnosis may be recommended to patients who experience procedural pain. Massage may be recommended to patients experiencing pain during palliative or hospice care. These recommendations are based on an intermediate level of evidence, benefit outweighing risk, and with moderate strength of recommendation. The quality of evidence for other mind-body interventions or natural products for pain is either low or inconclusive. There is insufficient or inconclusive evidence to make recommendations for pediatric patients. More research is needed to better characterize the role of integrative medicine interventions in the care of patients with cancer.Additional information is available at https://integrativeonc.org/practice-guidelines/guidelines and www.asco.org/survivorship-guidelines.

Use of Honey in the Management of Chemotherapy-Associated Oral Mucositis in Paediatric Patients

Background

Oral mucositis (OM) is a critical condition during chemotherapy in both adult and child cancer patients. Paediatric cancer patients have a higher prevalence of OM than adult cancer patients. Honey is a natural product that has been reported to have the best tissue healing properties. The present mini-review focused on the evaluation of the effectiveness of oral care with honey products in the treatment and prophylaxis of chemotherapy-induced OM in child patients.

Methods

A network of electronic English databases including CINAHL, CENTRAL, EMBASE, MEDLINE and PubMed, were used for primary search from April 2010 to April 2020. We have also considered data collected from ClinicalTrials.gov, Web of Science and Google Scholar. PRISMA software was used to build collective data. Controlled trials were included in this review and were critically appraised by Down and Black. The narrative synthesis was performed.

Results

A total number of 346 data of children and adolescents with cancer were considered in this short review. All patients were from three randomized controlled trial articles and two were non-randomised controlled trial articles. Based on the evidence so far revealed, honey may show an effect in the treatment and prophylaxis of OM. The analysis of collected data revealed that the probability value P<0.05. The honey enhanced recovery time and severity of OM were significantly compared with those without honey treatment receiving group of pediatric patients.

Conclusion

Honey not only has been shown to have the capability for healing injured tissues but it is also a more economical treatment, and it has fewer side effects compared to synthetic drugs. Honey or honey products can prevent chemotherapy-induced OM (CIOM) and be the best treatment to grade I, II and III CIOM. However, it is disappointing that studies involving children as patients were few, and limited data available so far.

Oral Mucositis Induced by Chemoradiotherapy in Head and Neck Cancer—A Short Review about the Therapeutic Management and the Benefits of Bee Honey

Background and Objectives: Oral mucositis, a severe non-hematological complication, can be induced by chemoradiotherapy. It is associated with severe local dysfunction, severely affecting the patient’s quality of life; it increases the risk of oral infections and interrupts oncological treatment, thus prolonging the duration and cost of hospitalization. Besides all of the agents used in the prevention and treatment of oral mucositis induced by oncological treatment, can there be found an easier one to administer, with an effective preparation, high addressability, both for adults and paediatric patients, without side effects, and at the same time cheap and easy to purchase? The aim of the present paper is to demonstrate the existence of this product, which is available to everyone, having multiple benefits. Materials and Methods: For the purpose of writing this article, materials were searched in electronic databases in between 2019 and 2021, taking into consideration papers where authors have demonstrated the effectiveness of this product through its topical or systemic use. Results: Numerous studies have highlighted the benefits of honey on oral mucositis. Through its analgesic, anti-inflammatory, anti-cancerous and antibacterial action, honey has proved to have a major impact on the patient’s quality of life and nutritional status by promoting tissue epithelialization and healing of the chemoradiotherapy-induced lesions. Conclusions: Superior to many natural agents, bee honey can be successfully used in both preventing and treating oral mucositis. There are currently numerous studies supporting and recommending the use of bee honey in the management of this oncological toxicity.

Effect of Honey on Pediatric Radio/Chemotherapy-Induced Oral Mucositis (R/CIOM): A Systematic Review and Meta-Analysis

Background

As a common side effect of radio/chemotherapy, oral mucositis severely affects patients' quality of life. Honey has been recommended for adults with radio/chemotherapy-induced oral mucositis (R/CIOM), but its effect for pediatric patients has not been systematically evaluated. Therefore, the aim of this systematic review and meta-analysis was to illuminate whether honey is effective in treating pediatric R/CIOM.

Methods

Two authors searched electronic databases including PubMed, Embase, the Cochrane Library, Web of Science, and Scopus to identify relevant studies, published in English. Then, the outcomes data was extracted from eligible studies and pooled in the meta-analysis.

Results

Totally, five studies containing 316 patients were included in our systematic review and meta-analysis. The result indicated that honey intervention significantly reduced the recovery time (MD = −5.10, 95% CI [−9.60, −0.61], P < 0.001, I² = 98%, random-effect model) in pediatric patients. Honey also reduced the occurrence of all grades of R/CIOM (RR = 0.19, 95% CI [0.12, 0.30], P < 0.001, I² = 0%, fixed-effect model) and the occurrence of grade III and grade IV R/CIOM (RR = 0.18, 95% CI [0.08, 0.41], P < 0.001, I² = 7%, fixed-effect model), and the sensitivity analysis showed the results were stable and robust.

Conclusion

Therefore, honey could be a competent candidate for the complementary treatment of pediatric R/CIOM.

Honey Bee Products: Preclinical and Clinical Studies of Their Anti-inflammatory and Immunomodulatory Properties

Inflammation is a defense process triggered when the body faces assaults from pathogens, toxic substances, microbial infections, or when tissue is damaged. Immune and inflammatory disorders are common pathogenic pathways that lead to the progress of various chronic diseases, such as cancer and diabetes. The overproduction of cytokines, such as interleukin (IL)-1β, IL-6, and tumor necrosis factor-α, is an essential parameter in the clinical diagnosis of auto-inflammatory diseases. In this review, the effects of bee products have on inflammatory and autoimmune diseases are discussed with respect to the current literature. The databases of Google Scholar, PubMed, Science Direct, Sci-Finder and clinical trials were screened using different combinations of the following terms: “immunomodulatory”, “anti-inflammatory”, “bee products”, “honey”, “propolis”, “royal jelly”, “bee venom”, “bee pollen”, “bee bread”, “preclinical trials”, “clinical trials”, and “safety”. Honey bee products, including propolis, royal jelly, honey, bee venom, and bee pollen, or their bioactive chemical constituents like polyphenols, demonstrate interesting therapeutic potential in the regulation of inflammatory mediator production as per the increase of TNF-α, IL-1β, IL-6, Il-2, and Il-7, and the decrease of reactive oxygen species (ROS) production. Additionally, improvement in the immune response via activation of B and T lymphocyte cells, both in in vitro, in vivo and in clinical studies was reported. Thus, the biological properties of bee products as anti-inflammatory, immune protective, antioxidant, anti-apoptotic, and antimicrobial agents have prompted further clinical investigation.

A Narrative Review about Nutritional Management and Prevention of Oral Mucositis in Haematology and Oncology Cancer Patients Undergoing Antineoplastic Treatments

Cancer is a prevalent disease worldwide, and treatments such as radiotherapy and chemotherapy sometimes lead to adverse events. Oral mucositis is one of the most disabling adverse events, and clinical guidelines do not take into account nutritional interventions. The primary endpoint was to gather the evidence about the efficacy of nutritional interventions in the prevention and/or treatment of antineoplastic-induced oral mucositis in oncological patients. A bibliographic review was carried out in the PubMed data base by combining MeSH terms with Boolean operators. Articles were selected based on inclusion and exclusion criteria; 50 final articles were found. Although further evidence is needed, glutamine, honey, and vitamins appear to be good therapeutic options. The rest of the compounds presented controversial or insufficient results, making it difficult to draw conclusions over their utilization as prevention or treatment options. Little evidence is reported about oral mucositis nutritional interventions in spite of them being attainable and affordable compounds. Scarce evidence is shown in paediatric patients compared with adults. Developing higher quality studies and combinations with the compounds researched is necessary for creating a stronger body of evidence.

Honey in wound healing: An updated review

Wound healing is a complex process with many interdependent pathophysiological and immunological mediators to restore the cellular integrity of damaged tissue. Cutaneous wound healing is the repair response to a multitude of pathologies induced by trauma, surgery, and burn leading to the restoration and functionality of the compromised cells. Many different methods have been employed to treat acute and chronic wounds, such as antimicrobial therapy, as most wounds are susceptible to infection from microbes and are difficult to treat. However, many antimicrobial agents have become ineffective in wound treatment due to the emergence of multiple drug-resistant bacteria, and failures in current wound treatment methods have been widely reported. For this reason, alternative therapies have been sought, one of which is the use of honey as a wound treatment agent. The use of honey has recently gained clinical popularity for possible use in wound treatment and regenerative medicine. With this high demand, a better delivery and application procedure is required, as well as research aiming at its bioactivity. Honey is a safe natural substance, effective in the inhibition of bacterial growth and the treatment of a broad range of wound types, including burns, scratches, diabetic boils (Skin abscesses associated with diabetic), malignancies, leprosy, fistulas, leg ulcers, traumatic boils, cervical and varicose ulcers, amputation, burst abdominal wounds, septic and surgical wounds, cracked nipples, and wounds in the abdominal wall. Honey comprises a wide variety of active compounds, including flavonoids, phenolic acid, organic acids, enzymes, and vitamins, that may act to improve the wound healing process. Tissue-engineered scaffolds have recently attracted a great deal of attention, and various scaffold fabrication techniques are being researched. Some incorporate honey to improve their delivery during wound treatment. Hence, the aim of this review is to summarize recent studies on the wound healing properties of honey.

Usefulness of Honey as an Adjunct in the Radiation Treatment for Head and Neck Cancer: Emphasis on Pharmacological and Mechanism/s of Actions

BACKGROUND

In the treatment of head and neck cancer (HNC), ionizing radiation is an important modality in achieving curative objectives. However, the effective use of radiation is compromised by the side effects resulting from the damage to the adjacent normal tissue. Preclinical studies carried out in the recent past have shown that the age old dietary agent honey, which also possess myriad medicinal use is beneficial in mitigating diverse radiation-induced side effects like mucositis, xerostomia, fatigue, weight loss and to promote healing of refractory wounds.

OBJECTIVE

The objective of this memoir is to review the beneficial effects of honey in mitigating radiation-induced side effects in HNC and to emphasize on the underlying mechanism of action for the beneficial effects Methods: Two authors searched Google Scholar, PubMed, Embase, and the Cochrane Library for publications up to December 2019 to assess the ability of honey in reducing the severity of radiation-induced ill effects in the treatment of HNC. Subsequently, the adjunct pharmacological effects and mechanism/s responsible were also searched for and appropriately used to substantiate the underlying mechanism/s of action for the beneficial effects.

RESULTS

The existing data is suggestive that honey is beneficial in mitigating the radiation-induced mucositis, xerostomia, healing of recalcitrant wounds in radiation exposed regions and multiple pathways mediate the beneficial effects especially, free radical scavenging, antioxidant, wound healing, anticancer, analgesic, anti-inflammatory, anabolic, anti-fatigue and anti-anaemic effects that add additional value to the use of honey as an adjunct in cancer therapy.

CONCLUSION

For the first time this review addresses the underlying pharmacological effects related to the beneficial effects of honey in radiation-induced damage, and attempts at emphasizes the lacunae that need further studies for optimizing the use of honey as an adjunct in radiotherapy of HNC. The authors suggest that future studies should be directed at understanding the detail molecular mechanisms responsible for the beneficial effects using validated cell culture and animal models of study. Large multi centric clinical trials with standardised honey is also needed to understand the clinical use of honey.

Clinical applicability of natural products for prevention and treatment of oral mucositis: a systematic review and meta-analysis

OBJECTIVE

A systematic review and meta-analysis was carried out to verify evidence regarding the efficacy and safety of the clinical applicability of natural products in the prevention and treatment of oral mucositis induced by chemotherapy and/or radiotherapy.

METHODOLOGY

An electronic research according to the PICOS strategy, using the terms "natural products" and "oral mucositis," was carried out at Pubmed, Cochrane, Embase, and "gray literature." The stages of eligibility, data extraction, and quality assessment of the studies were carried out independently and in duplicate.

RESULTS

The number of studies identified as eligible was 151, including 47 randomized controlled trials, reporting a total of 3075 participants undergoing some therapy with natural products on oral mucositis. The included clinical trials covered a variety of 31 types of natural products. Considering the risk of bias of the clinical trials, 24 studies (51.1%) were considered to have a low overall risk of bias, nine (19.1%) were at moderate risk, and 14 clinical trials (29.8%) were at high risk of bias. Honey was the most assessed natural agent. Fourteen studies (3.4%) reported that natural agents reduced pain.

CONCLUSION

The results of the meta-analysis support a positive effect of honey and Aloe vera in reducing mucositis in patients receiving cancer therapy.

CLINICAL RELEVANCE

The results found add relevant information to the scientific community regarding the prevention and treatment of mucositis. Graphical abstract.

MASCC/ISOO clinical practice guidelines for the management of mucositis: sub-analysis of current interventions for the management of oral mucositis in pediatric cancer patients

OBJECTIVE

The aim of this sub-analysis was to highlight the MASCC/ISOO clinical practice guidelines for the management of oral mucositis (OM) in pediatric patients and to present unique considerations in this patient population.

METHODS

This sub-analysis of the pediatric patient population is based on the systematic review conducted by the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISSO) published in 2019/2020. Studies were scored and assigned a level of evidence based on previously published criteria. Data regarding adverse effects and compliance was collected from the original publications.

RESULTS

A total of 45 papers were included and assessed in this sub-analysis, including 21 randomized controlled trials (RCTs). Chewing gum was demonstrated to be not effective in preventing OM in pediatric cancer patients in 2 RCTs. The efficacy of all other interventions could not be determined based on the available literature.

CONCLUSION

There is limited or conflicting evidence about interventions for the management of OM in pediatric cancer patients, except for chewing gum which was ineffective for prevention. Therefore, currently, data from adult studies may need to be extrapolated for the management of pediatric patients. Honey and photobiomodulation therapy in this patient population had encouraging potential. Implementation of a basic oral care protocol is advised amid lack of high level of evidence studies.

Honey and children: only a grandma's panacea or a real useful tool?

Honey is a natural product that has been used as medication since the ancient times for its nutritive and therapeutic value. Despite these properties, honey use has been limited in evidence-based medicine due to the lack of evidence in clinical settings, particularly in paediatric population. An increasing interest has grown towards honey during the last years. The aim of this article is to examine the possible role of honey as a therapeutic tool in paediatrics. We performed a literature search to summarise the highest quality evidences, analysed articles regarding honey's nutritional properties and therapeutic value. The state of the art is represented by evidences related to beneficiary effects of honey on respiratory, gastroenterological and oncohaematologic diseases. Many other uses could promisingly come from in vitro studies or clinical trial based on adult samples. Honey shows an excellent risk-benefit profile and can be safely administrated in children older than 12 months. In conclusion, honey does not only represent a grandma's remedy, but is a real useful tool in different clinical settings, including paediatrics practice. However, there is a need for high-quality, large randomised controlled trials confirming effectiveness and practical application of honey in paediatric population.

Comparative prevention potential of 10 mouthwashes on intolerable oral mucositis in cancer patients: A Bayesian network analysis

BACKGROUND

There is a wide variety of mouthwashes currently available for the prevention of intolerable oral mucositis (OM) onset. Because of a lack of evidence from head-to-head randomized controlled trials (RCTs), the relative effects of these mouthwashes in intolerable OM patients remain unclear. This study compared the preventive effect of ten mouthwashes in intolerable OM.

METHODS

A literature search was performed of the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, and MEDLINE (PubMed) databases. Reports published from 1990 to 2019 focusing on mouthwashes for preventing OM were identified. Authors assessed the studies' risk of bias in accordance with the Cochrane Handbook for Systematic Reviews of Interventions, and followed the PRISMA for Network Meta-Analyses Statement. Authors estimated summary odds ratios (ORs) using pairwise and Bayesian network meta-analysis with random effects.

RESULTS

Thirty-six RCTs, with a total of 2594 patients, were included in the present study. Bayesian network analysis showed that honey (Odd Ratio [OR] 0.17, 95%CI 0.09 to 0.30), chamomile (OR 0.09, 95% CI 0.01 to 0.52), curcumin (OR 0.23, 95% CI 0.08 to 0.67) and benzydamine (OR 0.26, 95% CI 0.12 to 0.54) mouthwashes were superior to placebo. Honey mouthwashes were more efficacious than chlorhexidine (OR 0.34, 95% CI 0.12 to 0.92), sucralfate (OR 0.26, 95% CI 0.06 to 0.96) and povidone-iodine (OR 0.30, 95% CI 0.11 to 0.82) mouthwashes. Other mouthwashes showed no significant differences.

CONCLUSIONS

According to the analysis of rank probabilities, chamomile, honey, curcumin and benzydamine mouthwashes may be the most advantageous in terms of the prevention of intolerable OM.

What is wrong with the meta-analyses on honey and oral mucositis due to cancer therapies?

OBJECTIVES

The results of meta-analyses currently represent the highest level of evidence in modern medicine. Taking the example of radiotherapy and radiochemotherapy-induced oral mucositis and the effects of honey, we analysed six meta-analyses on the topic to assess the quality of the meta-analyses.

DESIGN

We analysed the various meta-analyses in detail and compared whether the authors have correctly included the various trials or not.

RESULTS

We found that the quality of these meta-analyses was low. Especially the more recent meta-analyses included trials in which radiotherapy was not part of the medical intervention or where substances other than pure honey were used.

CONCLUSIONS

It is impossible to determine the underlying reasons why these meta-analyses were able to pass the peer-review system without the request for adequate improvements prior to publication. According to the literature at least 7% of the included meta-analyses revealed false results, but it was assumed that due to limitations of external validity and to the decreased likelihood of updating positive meta-analyses, the true proportion of false positives in the meta-analysis was likely to be higher. However, it is crucial that when severe flaws in meta-analyses are detected that they be reported or the meta-analyses are withdrawn, otherwise the normal reader will take the results as given.

The Relationship of Oral Care Practice at Home with Mucositis Incidence in Children with Acute Lymphoblastic Leukemia

Mucositis is a common and devastating side effect of chemotherapeutic agents in children undergoing chemotherapy. The prevention and management of mucositis are necessary to improve these children's quality of life. Oral care is a recommended strategy for preventing and managing oral mucositis. Thus, the objective of this study was to identify the relationship between oral care practice and mucositis incidence. A cross-sectional analytical design was used in this study. A total of 34 children from 3 to 12 years of age with acute lymphoblastic leukemia who were in the last cycle of chemotherapy were recruited through a snowball sampling method. The Oral Assessment Guide (OAG) was administered to assess the severity of mucositis. A majority of the participants (51.5%) had mucositis after completing the last cycle of chemotherapy. Furthermore, there was a statistically significant relationship between their oral care practice at home and mucositis incidence. These results show that oral care at home is linked with the incidence and severity of mucositis. Nurses should educate children with leukemia and their parents regarding good oral hygiene practice.

Complementary and integrative health methods used for the treatment of oral mucositis in children with cancer in Turkey

PURPOSE

We aimed to determine the complementary and integrative health (CIH) methods used by parents to treat oral mucositis in their children who have cancer.

DESIGN AND METHODS

In this multicenter, cross-sectional study, data for the study were collected via the demographic form and CIH form for oral mucositis. The data collection tools were filled out by the researchers during the face-to-face interviews. The parents (N = 302) of children with cancer who had undergone at least one round of chemotherapy were included in this study.

RESULTS

According to the parents' statements, oral mucositis developed in 91.1% of the children with cancer, and CIH was used in 50.9% of them to treat its side effects. Parents stated that to deal with the oral mucositis, they mainly used black mulberry (41.5%), carbonate (15.2%), and honey (11.6%). Some of the parents (51.8%) used CIH for their children without informing their healthcare providers.

PRACTICE IMPLICATIONS

The majority of healthcare providers were unaware of the parents' use of CIH for their children's oral mucositis treatment. Parents' opinions of these methods, of which the side effects and potential interactions with chemotherapeutic agents are not precisely known, and their use by parents for their children's oral mucositis should be evaluated by healthcare providers.

Prophylactic and therapeutic effects of honey on radiochemotherapy-induced mucositis: a meta-analysis of randomized controlled trials

PURPOSE

Oral mucositis is a common side effect of radiochemotherapy and may adversely affect the patients' quality of life (QoL). Honey application may reduce the mucositis grade in patients. Here, we conducted a meta-analysis of randomized controlled trials (RCTs) to evaluate the prophylactic and therapeutic effects of honey on radiochemotherapy-induced oral mucositis.

METHODS

Publications on RCTs were extracted from the PubMed, Embase, CINAHL, and Cochrane Library databases. The primary outcomes were mucositis grades and pain scores. Secondary outcomes were the recovery time and QoL. The study was registered with PROSPERO (number CRD42018108486).

RESULTS

Nineteen RCTs, involving 1276 patients, were reviewed. Honey considerably mitigated oral mucositis in both prophylactic and therapeutic phases. In the prophylactic phase, intolerable mucositis development was significantly prevented in the honey-treated group (RR = 0.18, 95% confidence interval [CI] = 0.09 to 0.41). Patients treated with honey showed significant decrease in pain scores in the first month of treatment (weighted mean difference [WMD] = - 3.25, 95% CI = - 4.41 to - 2.09) and at the end of the treatment (WMD = - 2.32, 95% CI = - 4.47 to - 0.18).

CONCLUSION

Honey, which is relatively cheap and easily available, prevented mucositis and effectively mitigate mucositis in patients after radiochemotherapy. Moreover, it significantly reduced the mucositis grade and engendered a fast and painless healing process. Therefore, honey use during and after radiochemotherapy is recommended for mucositis prevention and treatment.

The Effect of Oral Care with Chlorhexidine, Vitamin E and Honey on Mucositis in Pediatric Intensive Care Patients: A Randomized Controlled Trial

PURPOSE

This study was performed to determine the effect of oral care using chlorhexidine, vitamin E and honey on oral mucositis (OM) management in children treated in a pediatric intensive care unit (PICU).

DESIGN AND METHODS

The study was a randomized controlled trial with a parallel design. The study sample was composed of 150 children who were treated in the PICU of a university hospital in Turkey. Children enrolled in the study were randomly divided into six groups based on the oral care solutions used (n = 25 in each group). The Demographic Information Form and the World Health Organization Oral Mucositis Index were used for data collection.

RESULTS

The mucositis indices of the children presenting with and without OM upon admission to the PICU were compared on days 1, 3, 6, 9, 12, 15, 18 and 21 and the study found that the mucositis index values of the children treated with vitamin E were significantly lower than in the other groups (p < 0.05 for each), while those of the children given chlorhexidine were significantly higher than in the other groups (p < 0.05 for each).

CONCLUSIONS

At the end of the study, vitamin E was determined to be the most effective agent in OM management, followed by honey as the second most effective agent. Chlorhexidine was found to be less effective in OM management compared to the other two agents. Based on this, vitamin E is recommended for use in oral mucositis-preventive and therapeutic oral care practices.

PRACTICE IMPLICATIONS

The results of the present study conducted with PICU patients will be useful in the administration of oral care. These findings are also important for nurses who have the responsibility of oral mucositis management.

Natural Product Interventions for Chemotherapy and Radiotherapy-Induced Side Effects

Cancer is the second leading cause of death in the world. Chemotherapy and radiotherapy are the common cancer treatments. However, the development of adverse effects resulting from chemotherapy and radiotherapy hinders the clinical use, and negatively reduces the quality of life in cancer patients. Natural products including crude extracts, bioactive components-enriched fractions and pure compounds prepared from herbs as well as herbal formulas have been proved to prevent and treat cancer. Of significant interest, some natural products can reduce chemotherapy and radiotherapy-induced oral mucositis, gastrointestinal toxicity, hepatotoxicity, nephrotoxicity, hematopoietic system injury, cardiotoxicity, and neurotoxicity. This review focuses in detail on the effectiveness of these natural products, and describes the possible mechanisms of the actions in reducing chemotherapy and radiotherapy-induced side effects. Recent advances in the efficacy of natural dietary supplements to counteract these side effects are highlighted. In addition, we draw particular attention to gut microbiotan in the context of prebiotic potential of natural products for the protection against cancer therapy-induced toxicities. We conclude that some natural products are potential therapeutic perspective for the prevention and treatment of chemotherapy and radiotherapy-induced side effects. Further studies are required to validate the efficacy of natural products in cancer patients, and elucidate potential underlying mechanisms.

The effect of an oral care protocol and honey mouthwash on mucositis in acute myeloid leukemia patients undergoing chemotherapy: a single-blind clinical trial

OBJECTIVES

The purpose of the study is to evaluate and compare the effectiveness of honey mouthwash and an oral care protocol on mucositis and weight loss in patients with acute myeloid leukemia receiving chemotherapy.

MATERIALS AND METHODS

In this single-blind clinical trial, 53 acute myeloid leukemia (AML) patients receiving chemotherapy were randomly assigned into three groups: honey mouthwash (n = 17), oral care (n = 17), and control (n = 19). The severity of mucositis and weights was examined blindly at the baseline and 4-week follow-up.

RESULTS

The prevalence of grades of mucositis in the study groups was significant at the end of the third (p = 0.002) and fourth (p < 0.001) weeks. The mucositis severity decreased at the end of the third and fourth weeks in the honey mouthwash group (p < 0.05), whereas it increased in the control group (p < 0.001). The difference in the weight was significant between the honey mouthwash and the control groups (p < 0.05, MD = 1.95) at the end of the third week, and between the honey mouthwash group with the control (p < 0.01, MD = 2.92) and oral care groups (p < 0.05, MD = 1.95) at the end of the fourth week.

CONCLUSIONS

Honey mouthwash is effective in preventing and reducing the severity of mucositis, and weight loss and can be recommended for patients undergoing chemotherapy.

CLINICAL RELEVANCE

The results of this study suggest that honey mouthwash can reduce the incidence and severity of mucositis in patients, reduce or eliminate the possibility of weight loss in them, as well as encourage some weight gain. Compared to routine oral care, honey mouthwash is also easier to use and handle.

Adjunctive Treatments for the Prevention of Chemotherapy- and Radiotherapy-Induced Mucositis

Background: Chemoradiotherapy-associated mucositis can manifest as pain, inflammation, dysphagia, diarrhea, weight loss, rectal bleeding, and infection. Mucositis is a major dose-limiting side effect of chemotherapy, affecting nutritional intake and oral and intestinal function. Despite several interventions being available, there is a need for safe and effective preventative and treatment options for treatment-induced mucositis. The goals of this review are to discuss interventions based on foods and natural products and present the research to date. Methods: A narrative literature review identified 60 clinical studies examining various nutritional compounds and 20 examining probiotics. 9 studies on probiotics for the prevention of diarrhea were also assessed on methodological quality and limitations identified. Results: Several compounds have been posited as useful adjuvants for cancer treatment–related mucositis. Probiotics demonstrate efficacy for the prevention and treatment of chemoradiotherapy-induced gastrointestinal toxicity without significant side effects. Glutamine and activated charcoal were reported to reduce chemotherapy-induced diarrhea but not radiation-induced intestinal mucositis. Honey has been reported to decrease treatment interruptions, weight loss, and delays the onset of oral mucositis. Zinc, glutamine, and topical vitamin E were demonstrated efficacy for oral mucositis. Conclusion: There is plausible clinical evidence for the administration of several adjunctive treatments for the prevention and treatment of mucositis. Probiotics were reported to reduce the burden of intestinal mucositis and treatment-induced diarrhea. Activated charcoal and glutamine are beneficial for chemotherapy-induced diarrhea, whereas the administration of honey, zinc, and glutamine reduce the risk of developing oral mucositis during chemotherapy or radiotherapy.

Global Health Journal Club: Is Honey Effective as a Treatment for Chemotherapy-induced Mucositis in Paediatric Oncology Patients?

Oral mucositis (OM) is an inflammatory response of mucosal epithelium to the cytotoxic effects of chemotherapy and radiotherapy causing severe oral pain and ulceration, which may complicate the management of cancer. The Mucositis Prevention Guideline Development Group has developed an international guideline for the prevention of mucositis in children receiving treatment for cancer or undergoing haematopoietic stem cell transplantation. Evidence-based preventative strategies include cryotherapy, low-level light therapy and keratinocyte growth factor. However, these strategies are often not available in resource-poor settings. There is some evidence that honey may be a suitable treatment for OM in adult patients. We performed a literature search of 11 databases to find papers exploring the use of honey to treat chemotherapy-associated mucositis in paediatric oncology patients. We found four papers, which provide Grade C evidence that honey is effective as a preventative and therapeutic measure for OM in paediatric oncology patients.

Propolis and Its Potential to Treat Gastrointestinal Disorders

There are a number of disorders that affect the gastrointestinal tract. Such disorders have become a global emerging disease with a high incidence and prevalence rates worldwide. Inflammatory and ulcerative processes of the stomach or intestines, such as gastritis, ulcers, colitis, and mucositis, afflict a significant proportion of people throughout the world. The role of herbal-derived medicines has been extensively explored in order to develop new effective and safe strategies to improve the available gastrointestinal therapies that are currently used in the clinical practice. Studies on the efficacy of propolis (a unique resinous aromatic substance produced by honeybees from different types of species of plants) are promising and propolis has been effective in the treatment of several pathological conditions. This review, therefore, summarizes and critiques the contents of some relevant published scientific papers (including those related to clinical trials) in order to demonstrate the therapeutic value of propolis and its active compounds in the treatment and prevention of gastrointestinal diseases.

Honey Mitigates Radiation-Induced Oral Mucositis in Head and Neck Cancer Patients without Affecting the Tumor Response

Radiation-induced mucositis is a dose-limiting factor in the effective treatment of head and neck (H & N) cancers. The objective of this study was to understand the efficacy of honey in mitigating radiation-induced mucositis and whether it would interfere with tumor control. This was a single-blinded, randomized, controlled study and was carried out in patients with H & N cancer requiring curative radiotherapy (>62 Gy (Gray)). The patients meeting the inclusion criteria were randomly assigned to receive either honey (n = 25) or povidone-iodine (active comparator) (n = 25) during radiotherapy. Oral mucositis was assessed using the RTOG (Radiation Therapy Oncology Group) grading system before the start, during, and at the end of the treatment by an investigator unaware of the treatment. The results indicate that when compared with the active comparator, honey reduced the radiation-induced oral mucositis, decreased the incidence of intolerable mucositis, treatment breaks, loss of treatment days (p < 0.0001 and < 0.0003) and did not affect the radiation-induced tumor response. The clinical observations indicate that honey mitigates the radiation-induced mucositis and does not interfere with tumor cell killing.
