Moringa oleifera regulates the health of people living with HIV in developing countries: a systematic review

If left untreated, HIV has the potential to increase morbidity and mortality rates to 14 times higher than that of HIV and AIDS-free persons of the same sex and age group. Currently, treatment of HIV is by use of ART, which has proved to prolong the lives of people living with HIV (PLWHIV). In addition to ART, HIV patients opt to also use traditional medicines. Moringa oleifera is one of the traditional herbs that is used by HIV patients in developing countries. However, its use is only recommended by non-professionals due to a lack of consensus on the impact of moringa on the health of PLWHIV. Therefore, the goal of this review is to investigate the impact of moringa oleifera on health-related quality of life of PLWHIV. Three scientific databases were accessed from 1 July to 31 August 2022 using as key words "moringa oleifera", "health outcomes", herbal supplementation" and "traditional medicines". Articles published in peer-reviewed journals were selected. 20 articles were retrieved, and 11 articles were excluded since they either did not use a randomised control study design, or were a review. The articles reviewed indicated that moringa supplementation resulted to increases in CD4 cell count and body mass index, improvements in psychological well-being, in management of depression and anxiety and the function of vital body organs and control of cholesterol levels. In conclusion, use of moringa oleifera supplementation improves the health of PLWHIV. It is therefore recommended that health personnel should consider the use of moringa oleifera alongside ART to ensure optimal treatment outcomes.

Does <em>Moringa oleifera</em> Lam. leaves supplementation have an impact on the weight and bone mass index of people living with HIV that are on antiretroviral therapy? A double-blind randomized control trial

Background

HIV-related weight loss and wasting were the most common malnutrition and AIDS-defining conditions before HAART. HAART has led to more obese PLHIV. HIV-positive patients should eat micro- and macronutrient-rich foods to maintain optimal nutrition. This study examined whether Moringa oleifera Lam. leaf supplementation affects PLHIV receiving ART.

Methods

A randomized, double-blind, controlled trial was conducted. Two hundred patients with informed consent were randomly assigned to either the Moringa oleifera Lam. (MOG) group or the control group (COG). From baseline to six months of Moringa oleifera Lam. leaf supplementation, anthropometric parameters [weight; BMI] of the participants were assessed.

Results

One hundred seventy-seven patients completed the 6-month follow-up (89 MOG vs. 88 COG). During the study period, the MOG and COG had similar weights and BMIs (p>0.05). At baseline and six months, most participants in both study groups had a healthy BMI (18.5-24.9). Many participants were overweight; few were underweight ((BMI <18.5). MOG and COG BMI differences at baseline and six months were not significant (p> 0.05). All experiments were 95CI.

Conclusions

Moringa oleifera Lam. leaf powder had no effect on HIV-positive adults receiving antiretroviral therapy, in accordance with this study.

Dietary diversity and impact of Moringa oleifera Lam. leaves supplemented - Diet on the nutritional status and CD4 cell counts of patients receiving antiretroviral therapy in Nigeria: A double - Blind randomized trial

Background

To maintain an optimal nutritional status and immunological function in PLHIV, a diet with adequate nutrients is of utmost importance. This is a major challenge among poor populations in developing worlds like Nigeria, where malnutrition and food insecurity are endemic. This study aimed to assess the type of regular diet consumed and assess the impact of supplementation of the diet with Moringa oleifera Lam. leaves on the nutritional status and CD4 cell counts of PLHIV that are on ART in Nigeria.

Method

A double-blind, randomized trial was conducted. Two hundred consented patients were randomly allocated to either the Moringa oleifera Lam. group (MOG) or the control group (COG). The FAO individual dietary diversity questionnaire was used. The regular diets of participants at baseline and six months were monitored. The measurements of weight, BMI, MUAC, and CD4 cell counts were obtained from baseline to six months of Moringa oleifera Lam. leaves supplementation.

Results

One hundred and seventy-seven patients completed the six-month follow-up (89 MOG versus 88 COG). At both baseline and sixth month, the foods most commonly consumed by the participants in both MOG and COG were cereals, spices and condiments, oils, fats and palm oil, and dark green vegetables. At baseline, significantly higher consumption of legumes, nuts & seeds (p = 0.001) was observed in the MOG and higher consumption of other vegetables (p = 0.024) in COG. Consumption of cereals, roots, and tubers was significantly higher (p = 0.024; 0.045) in the COG in the sixth month. In both groups, participants were in the medium or low dietary diversity tercile. Throughout the study period, all the nutritional status variables observed were not significantly different between the two study groups [(p > 0.0001); weight; p = 0.5556; BMI; p = 0.5145; MUAC; p = 0.6456]. Over the study period, the treatment by time interaction shows a significant difference in CD4 counts by treatment group (p < 0.0001) and an estimate of fixed effects 10.33 folds greater in the MOG than COG. All tests were conducted at 95CI.

Conclusion

This study revealed a poor dietary diversity amongst PLHIV. Supplementation of regular diet with Moringa oleifera Lam. leaves did not affect the nutritional status but could improve the immune response of HIV-positive adults attending the antiretroviral treatment centre in the present study area.

A double-blind, randomized controlled trial to examine the effect of Moringa oleifera leaf powder supplementation on the immune status and anthropometric parameters of adult HIV patients on antiretroviral therapy in a resource-limited setting

BACKGROUND

People living with HIV (PLHIV) in resource-limited settings are vulnerable to malnutrition. Nutritional interventions aimed at improving food insecurity and malnutrition, together with antiretroviral therapy (ART), could improve treatment outcomes. In Nigeria, there is a high awareness of the nutraceutical benefits of Moringa oleifera. Thus, this study aimed to evaluate the effects of Moringa oleifera leaf supplementation on the CD4 counts, viral load and anthropometric of HIV-positive adults on ART.

METHODS

This was a double-blind, randomized study. Two hundred HIV-positive patients were randomly allocated to either the Moringa Oleifera group (MOG) given Moringa oleifera leaf powder or the control group (COG) given a placebo. Changes in anthropometric parameters [weight; body mass index (BMI)] and CD4 cell counts were measured monthly for six months, while HIV-1 viral loads were measured at baseline and the end of the study for both groups.

RESULTS

Over the study period, the treatment by time interaction shows a significant difference in CD4 counts by treatment group (p<0.0001). A further estimate of fixed effects showed that the CD4 counts among MOG were 10.33 folds greater than COG over the study period. However, the viral load (p = 0.9558) and all the anthropometric parameters (weight; p = 0.5556 and BMI; p = 0.5145) between the two groups were not significantly different over time. All tests were conducted at 95CI.

CONCLUSION

This study revealed that Moringa oleifera leaf supplementation was associated with increased CD4 cell counts of PLHIV on ART in a resource-limited setting. Programs in low-resource settings, such as Nigeria, should consider nutritional supplementation as part of a comprehensive approach to ensure optimal treatment outcomes in PLHIV.

Impact of Moringa Oleifera leaves supplementation on quality of life of people living with HIV: A double-blind randomized controlled trial

PURPOSE

Advances in antiretroviral therapy (ART) and increased interest on nutritional interventions have led to improvements in life expectancy of people living with HIV (PLHIV). These have led to greater emphasis on their quality of life (QoL). This study was aimed at exploring the effects of Moringa oleifera leaves supplementation on QoL of HIV-positive adults in Nigeria.

METHOD

A double-blind randomized controlled trial was conducted to determine the six months' impact of consuming Moringa oleifera leaves powder as a nutritional supplement on the different domains of QoL of PLHIV that are on ART. Two hundred consented patients were randomly allocated to either Moringa Oleifera group (MOG) or control group (COG). The WHOQOL-HIV-BREF was used to assess QoL at baseline and at six-month follow-up.

RESULTS

One hundred and seventy seven patients completed the study. At six-month follow-up, a significant (p < 0.05) increase in the mean scores of all the six domains of QoL was observed in the MOG. However, in the COG, a significant increase was observed in the social relationship, environment, and spirituality/religion/personal beliefs domains. The comparison between the MOG and COG at 6 months' follow-up showed a significant mean score difference in the MOG in the physical, psychological, level of independence, and social relationships domains of QoL.

CONCLUSION

This study shows that supplementation with Moringa oleifera leaves for PLHIV that are on ART improves the QoL domains of physical, psychological, level of independence, and social relationships. Clinical Trial Registry registration number: PACTR201811722056449.

Use of Moringa oleifera leaves in broiler production chain. 1 - Effect on Sasso breeder hens performances, internal quality of hatching eggs and serum lipids

An experiment was conducted to determine the effect of Moringa oleifera leaves (MOL) on breeder hen performance, hatching egg quality and blood parameters. A total of 180 Sasso broiler breeder hens were used for the study. They were allotted to two groups each containing 3 replicates of 30 hens of 18 weeks of age. Dietary treatments were a control diet (basal diet without moringa leaves) and a diet containing 10g of moringa leaves in 1kg of control diet (1% w/w). The experiment lasted 40 weeks. The following production parameters; feed intake, egg weight, laying rate and feed conversion ratio were measured for the whole experimental period while egg quality and blood parameters were assessed at different ages. Results showed that laying rate and hatching egg weight were improved by moringa meal diet for the whole experimental period. Feed intake and feed conversation ratio were decreased (p < .05) by incorporation of moringa leaves. Differences (p < .01) were observed in albumen and yolk ratio at 55th week of age. Yolk colour was (p < .001) improved by moringa meal at 31st, 43rd and 55th week of age. At the end of the experiment, serum concentrations of triglycerides, total cholesterol, low‐density lipoprotein cholesterol and atherogenic index were decreased (p < .05) while high‐density lipoprotein cholesterol was unaffected (p > .05) by incorporation of moringa in the diet. It was concluded that the use of moringa leaves as feed additive in Sasso breeders diet improved productivity and quality of hatching eggs.

Use of Moringa oleifera leaves as feed additive improve broiler breeders’ performances, number and weight of hatching eggs; and yolk colour. Except HDL cholesterol, serum lipids and atherogenic index are reduced by this phytobiotic.

Effect of Moringa oleifera consumption on diabetic rats

BACKGROUND

Therapeutic use of leaves of M. oleifera has been evaluated in diabetes because of its possible capacity to decrease blood glucose and lipids concentration after ingestion, as result of the polyphenols content and others compounds. Nevertheless most results have been obtain from leaf extract, therefore this study would use leaf powder as the regular way of consumption of population to know effects over toxicity glucose, triglycerides, cholesterol, corporal weight, and predominant groups of microbiota.

METHODS

Powdered leaf was administrated in different doses to know toxicity and genotoxicity using LD50 and micronuclei assay. Hyperglycemia was induced by alloxan on Sprague Dawley rats. Glucose and body weight were measured once a week meanwhile cholesterol and triglycerides were analyzed at the end of the study by commercial kits. Different organs were examined by hematoxylin-eosin technique. Lactic acid bacteria and Enterobacteriaceae were enumerated from stool samples.

RESULTS

The tested doses revealed no lethal dose and no significant differences in genotoxicity parameter. The consumption of the leaves showed a hypoglycemic effect (< 250 mg/dL in diabetic M. oleifera treated group), however in corporal weight showed an increased (> 30 g over no M. oleifera treated groups). There was no change in enumeration of lactic acid bacteria (8.4 CFU/g) but there were differences in the predominance of type of lactobacillus and enterobacteria enumeration.

CONCLUSIONS

These results help to increase information over the most popular use of M. oleifera and its safety. However there are needed more studies over the hypoglycemic mechanisms and effects over intestinal microbiota.

Impact of Moringa oleifera lam. Leaf powder supplementation versus nutritional counseling on the body mass index and immune response of HIV patients on antiretroviral therapy: a single-blind randomized control trial

BACKGROUND

To achieve effective antiretroviral therapy (ART) outcomes, adherence to an antiretroviral regimen and a good immunometabolic response are essential. Food insecurity can act as a real barrier to adherence to both of these factors. Many people living with human immunodeficiency virus (PLHIV) treated with ART in the Democratic Republic of the Congo (DRC) are faced with nutritional challenges. A significant proportion are affected by under nutrition, which frequently leads to therapeutic failure. Some HIV care facilities recommend supplementation with Moringa oleifera (M.O.) Lam. leaf powder to combat marginal and major nutritional deficiencies. This study aims to assess the impact of M.O. Lam. leaf powder supplementation compared to nutritional counseling on the nutritional and immune status of PLHIV treated with ART.

METHODS

A single-blind randomized control trial was carried out from May to September 2013 at an outpatient clinic for HIV-infected patients in Kinshasa (DRC). Sixty adult patients who were at stable HIV/AIDS clinical staging 2, 3 or 4 according to the World Health Organization (WHO), and were undergoing ART were recruited. After random allocation, 30 patients in the Moringa intervention group (MG) received the M.O. Lam. leaf powder daily over 6 months, and 30 in the control group (CG) received nutritional counseling over the same period. Changes in the body mass index (BMI) were measured monthly and biological parameters were measured upon admission and at the end of the study for the patients in both groups.

RESULTS

The two study groups were similar in terms of long-term nutritional exposure, sociodemographic, socioeconomic, clinical, and biological features. At 6 months follow-up, patients in the MG exhibited a significantly greater increase in BMI and albumin levels than those in the CG. The interaction between the sociodemographic, clinical, and biological characteristics of patients in the two groups was not significant, with the exception of professional activity.

CONCLUSIONS

Under medical supervision, M.O. Lam. leaf powder supplementation may represent a readily available and effective local solution to improve the nutritional intake and nutritional status of PLHIV undergoing ART.

TRIAL REGISTRATION

The study was retrospectively registered in the Pan African Clinical Trial Registry on 15 May 2015, no. PACTR201505001076143.
