Pesticide Residue Analysis of Khat Leaves and Health Risks among Khat Chewers in the Amhara Region, Northwestern Ethiopia.

Introduction: Farmers use a large number of pesticides to increase the productivity of Khat cultivation. Since Khat is consumed by many Ethiopians as a habit, there may be a significant concentration of pesticide residues in Khat leaves which result in adverse effects among the exposed population. Excess use of pesticides in Khat causes cancer, genotoxicity, and endocrine disturbances. The current study aimed to determine the concentration of selected pesticide residues on Khat leaves samples and to estimate the possible health risk on consumers. Methods: Thirty Khat samples were collected from Khat cultivators in the Amhara region, Ethiopia. Pesticide residue extraction and cleanup of Khat samples were performed using the QuEChERS method. Data were also collected about personal variables and Khat consumption habits. The pesticide concentrations were determined and the health risks were estimated. Results: Profenofos, dimethoate, and chlorpyrifos were detected in 6 (20%), 24 (80%), and 28 (93.3%) Khat samples, respectively. However, diazinon was detected in two samples and endosulfan I was not detected. The average concentration of chlorpyrifos, dimethoate, profenofos, and diazinon in Khat samples was 75.39 ± 20.26, 130 ± 48.94, 242.45 ± 119.79, and 81.5 ± 21.0 µg/kg, respectively. The HQ for diazinon was greater than 1 which shows the chronic health risks associated with intake of diazinon among Khat chewers. The acute health risks associated with intake of profenofos and diazinon were minimal. Discussion. Pesticide residue exposure is a risk factor for cardiac complications, reduction in antioxidant defense system, and developing neurological symptoms. All the pesticides were higher than the European Union Maximum Residue Levels (EU-MRL). Diazinon has the potential to cause higher chronic health risks. Chronic Khat chewers in the region may face potential health risks from pesticide residues. Awareness creation among people in the study area is necessary to avoid the adverse health effects of pesticide residues.

A cross sectional study on beliefs and roles of community pharmacy professionals in preventing and managing metabolic syndrome in an Ethiopian setting.

INTRODUCTION: Metabolic syndrome (MetS) is a group of cardiovascular risk factors, and its prevalence is becoming alarmingly high in Ethiopia. Studies uncovered as community pharmacy professionals (CPPs) have not yet well integrated into public health programs and priorities. In low income setting like Ethiopia, evidence regarding the roles CPPs in preventing and management of MetS is dearth. OBJECTIVE: The study was aimed to assess community pharmacy professionals'(CPPs) opinions about metabolic syndrome, describe their perception level towards the effectiveness of the main interventions and explore their extent of involvement in counseling patients with the metabolic syndrome in Gondar town, Northwestern Ethiopia. METHOD: A descriptive, cross-sectional study was conducted among pharmacists and druggists working in community medication retail outlets (CMROs) in Gondar town, northwestern Ethiopia from April 1 to May 31, 2019. Data were collected using a self-administered pre-tested questionnaire. Descriptive statistics was used to summarize different variables, and presented in tables and figure. An independent t-test and one way ANOVA (Analysis of Variance) were used to compare mean scores. A 5% level of significance was used. RESULT: Out of the 75 CPPs approached, 65(40 pharmacists and 25 druggists) completed the survey giving a response rate of 86.7%. Smoking cessation practice was identified to be low. There were a statistically significant difference (t = 2.144, P = 0.036) in the involvement towards counseling patients between CPPs who claimed to work in pharmacy (mean = 3.96 out of 5 points Likert scale) and drug stores (mean = 3.80 out of 5 points Likert scale). CONCLUSION: The study concluded that the overall involvement of professionals in counseling patients, opinion about metabolic syndrome, and perception towards the effectiveness of the intervention was found to be more or less positive. However, the provision of services, such as monitoring therapy, selling equipment for home blood pressure and glucose monitoring and documenting patient care services needs to be encouraged. Given proper education and training, the current study hope that community pharmacists could be an important front-line contributors to contain this emerging epidemic in Gondar town as well as in the entire nation.
