The aim of this work is to describe real-world biologic-experienced psoriasis patients initiating ixekizumab by prior biologic therapy status and compare the effectiveness of ixekizumab between patients who previously failed secukinumab and those who failed other biologics. We hypothesized that (1) clinical outcomes and patient-reported outcomes would improve following a switch to IXE, and (2) there would be no differences in responses between patients who previously failed secukinumab and those who failed other biologics.Participants (n = 419) included adult psoriasis patients enrolled in the CorEvitas Psoriasis Registry through 9/10/20 who switched to ixekizumab after discontinuing another biologic. Patients were classified by the biologic used immediately prior to ixekizumab and reason for discontinuation: prior secukinumab failure; prior secukinumab non-failure; prior other biologic failure; and prior other biologic non-failure. Discontinuations for efficacy reasons were considered failures; all others were considered non-failures. Baseline descriptive statistics were calculated. Multivariable Poisson regression models estimated the likelihood of response of other failure relative to secukinumab failure.Mean age was 51 years; 48% were women. Psoriasis disease characteristics were similar across prior biologic groups. At 6-month follow-up, disease severity improved for all who initiated ixekizumab after discontinuing another biologic. Secukinumab failure patients who switched to ixekizumab achieved BSA ≤ 1 (49%), BSA ≤ 3 (59%), PASI75 (46%), PASI ≤ 3 (64%), and IGA ≤ 1 (40%). Other failure patients achieved BSA ≤ 1 (55%), BSA ≤ 3 (72%), PASI75 (59%), PASI ≤ 3 (74%), and IGA ≤ 1 (54%). In regression modeling, we observed patients in the other biologics failure group had an increased likelihood of achieving response for BSA ≤ 3, PASI75, PASI90, PASI100, and IGA ≤ 1 compared to patients who failed secukinumab.These findings suggest that patients with psoriasis who switch to ixekizumab after discontinuing another biologic demonstrate improvement in disease severity after six months. Patients who discontinued biologics other than secukinumab may be more likely to respond to ixekiziumab compared to those who switched from secukinumab.

Limited real-world data are available comparing multiple biologics on their adherence, persistence, and the use of concomitant biologics in the treatment of moderate-to-severe psoriasis in clinical practice. The objective was to compare persistence of and adherence to ixekizumab (IXE) treatment, as monotherapy or with concomitant medication, versus patients receiving other commonly prescribed biologics.Patients who newly initiated IXE, adalimumab (ADA), etanercept (ETN), secukinumab (SEC), or ustekinumab (UST) in IBM MarketScanA higher proportion of patients receiving IXE had had previous biologic therapies (50.3%) versus other biologics (ADA: 9.1%, ETN: 10.9%, SEC: 33.9%, UST: 19.7%). Patients treated with IXE showed statistically (p 0.001) greater persistence than patients treated with SEC, ADA, UST, or ETN at both 1-year follow-up and up to 3 years of follow-up. Adherence for patients treated with IXE was significantly (p 0.001) higher compared to ADA, ETN, and UST at both 1-year follow-up and up to 3 years of follow-up. There was no significantly higher adherence in patients treated with IXE compared to those treated with SEC at 1-year follow-up, but IXE had higher adherence than SEC (p 0.05) at 1-3 year follow-up. IXE showed longer time on monotherapy than ADA (p 0.001), ETN (p 0.001), SEC (p 0.05), and UST (p 0.001) for both 1-year and 1-3 year follow-up. Sensitivity analyses on persistence, adherence, and monotherapy with further model adjustments after IPTW confirmed the findings.Patients treated with IXE were more persistent on and adherent to treatment and remained on monotherapy longer compared to those on all other commonly prescribed biologics combined or with individual biologics.

Objective To describe adherence, persistence, discontinuation, restarting, switching, dosing, and health care costs among patients with psoriatic arthritis (PsA) treated with ixekizumab (IXE). Methods MarketScan administrative claims databases were used to select adults (≥18 years) initiating IXE between January 1, 2016, and June 30, 2019, for this retrospective study (earliest IXE claim = index). Eligible patients had one or more PsA diagnoses during the 12 months preceding the index and had 12 months of follow‐up time after the index. Adherence (measured by proportion of days covered [PDC]) persistence ( 0.80)to IXE prior to discontinuation. Dose values were consistent with prescribing information for patients with and without comorbid psoriasis. Although IXE costs ($5233 [SD = $2497]) accounted for 85.6% of PsA‐related health care costs, only 3.5% of IXE costs were patient out‐of‐pocket expenses. Adjusting for the ICER discounts decreased all‐cause and PsA‐related costs by $2509 PPPM. Conclusion Results from this real‐world analysis suggest that treatment patterns and costs among patients with PsA initiating IXE are consistent with prior literature for other biologics.

The aim of this study was to compare healthcare costs between ixekizumab (IXE)-treated and secukinumab (SEC)-treated patients with psoriasis over a 24-month follow-up period in the United States.Patients with psoriasis diagnosis were identified from IBM Watson Health MarketScanOverall, 1461 patients (IXE users, n = 471; SEC users, n = 990) were included. IXE versus SEC users had higher weighted PPPM all-cause, psoriasis-related, and index drug costs (p ≤ 0.001). IXE versus SEC users had comparable ICER-adjusted mean PPPM all-cause costs (US$4172 ± 3349 vs US$3978 ± 2619; p = 0.227) and psoriasis-related costs (US$2950 ± 1332 vs US$2899 ± 1152; p = 0.447). After applying ICER and adherence adjustments, index drug costs were similar between IXE and SEC users (US$3794 ± 1822 vs US$3766 ± 1973; p = 0.795).All-cause and psoriasis-related costs were comparable between IXE and SEC users after ICER adjustments; index drug costs were similar after ICER and adherence adjustments.

Background: Real-world data on patients newly initiating ixekizumab is limited. Our study describes the characteristics of patients who initiated ixekizumab and other biologics for psoriasis treatment in North American dermatological practices. Materials & methods: Characteristics of patients ascertained at registry enrollment are described via means and frequencies. Results: Compared with other biologic initiators, ixekizumab initiators had: longer disease duration (17.1 vs 15.1 years); more were considered least severe by body surface area (33 vs 26%); moderate-to-severe by IGA (56 vs 48%); were biologic-experienced (80 vs 52%); obese (54 vs 47%); and experienced greater impact in work productivity (5.3 vs 2.9%) versus other biologic initiators. Conclusion: Psoriasis patients initiating ixekizumab had more severe disease, biologic experience, and worse patient-reported outcomes than those initiating other biologics.

To compare long-term healthcare resource utilization (HCRU) and costs among patients who initiated ixekizumab (IXE) or adalimumab (ADA) for treatment of psoriasis in the United States.Adult patients with psoriasis who had ≥1 claim for IXE or ADA were identified from IBM MarketScan claims databases prior to the COVID-19 pandemic (1 March 2016-31 October 2019). The index date was the date of first claim for the index drug of interest. Inverse probability of treatment weighting was employed to balance treatment cohorts. All-cause and psoriasis-related HCRU and costs were examined for 24 months of follow-up. Costs were reported as per patient per month. Costs of psoriasis-related biologics were adjusted using published Institute for Clinical and Economic Review (ICER) discount factors. Index drug costs were adjusted for adherence and ICER discount rates.The analyses included 407 IXE and 2,702 ADA users. IXE users had significantly higher inpatient admission rate (all-cause HCRU: 14.9% vs. 11.0%;Study relied on administrative claims data, subjected to data coding limitations and data entry errors. Rebates, patient assistance programs, and commission to wholesalers are not always captured in claims. Adjustment made by ICER discount factors may lead to double-discounting if the discounts have been applied in claim payments.All-cause HCRU was higher in IXE than ADA users. Healthcare costs were also higher in IXE than ADA users after ICER adjustment, over 24 months. Cost differences were largely driven by higher treatment adherence associated with IXE. Index drug costs were comparable after ICER and adherence adjustments.

Background There is lack of real-world treatment pattern comparison data between ixekizumab and adalimumab which are approved for the treatment of moderate-to-severe plaque psoriasis. Objective To compare real-world treatment patterns among psoriasis patients initiating ixekizumab or adalimumab in the United States. Methods Psoriasis patients with ≥1 claim for ixekizumab or adalimumab between March 1, 2016, and May 31, 2018, were identified (index date = date of first ixekizumab or adalimumab claim) from the IBM Watson Health MarketScan® databases. Patients were required to be continuously enrolled for ≥12 months before the index date and followed for a minimum of 6 months until inpatient death, enrollment end, or study end, whichever occurred first. Treatment persistence, adherence, discontinuation, restart, and switching were analyzed. Inverse probability of treatment weighting and multivariable regression modeling were employed to address cohort imbalances and estimate the adjusted risk of non-persistence, discontinuation, and switching, and the odds of adherence. Results A total of 646 ixekizumab and 3668 adalimumab users were included and followed for a mean of 14.0 and 16.5 months, respectively. Compared to adalimumab, ixekizumab was associated with 19% lower risk of non-persistence (hazard ratio [HR]=0.81, 95% confidence interval [CI]: 0.69-0.95), 26% lower risk of discontinuation (HR=0.74, 95% CI: 0.62-0.88), and 28% lower risk of switching (HR=0.72, 95% CI: 0.57-0.91). Ixekizumab users had higher odds of medication possession ratio ≥80% (odds ratio [OR]=1.36, 95% CI: 1.10-1.69) but similar odds by proportion of days covered ≥80% (OR=1.22, 95% CI: 0.98-1.53). Conclusion Psoriasis patients treated with ixekizumab demonstrated longer persistency, higher adherence and were less likely to discontinue or switch treatment compared to adalimumab users. However, while patients achieving highly adherent threshold significantly differed by MPR ≥80%, it did not by PDC ≥80%; hence, further analysis using fixed-length follow-up is required.

Introduction Real-world data comparing effectiveness of ixekizumab (IXE) and secukinumab (SEC) among biologic-experienced patients are limited. This study compared treatment patterns over 18 months among biologic-experienced patients with psoriasis receiving IXE or SEC in the USA. Methods A retrospective observational study using administrative claims data from IBM® Watson Health MarketScan® Research Databases included adult patients with ≥ 1 inpatient or ≥ 2 non-diagnostic (≥ 30 days apart) outpatient claim/s with diagnosis of psoriasis between March 1, 2015 and October 31, 2019, and ≥ 1 claim/s for index drugs, IXE or SEC, between March 1, 2016 and October 31, 2019. Patients had to have ≥ 1 claim/s for biologics indicated for psoriasis in the 6-month pre-period. During the 18-month follow-up, treatment adherence (proportion of days covered [PDC]), high adherence (PDC ≥ 80%), persistence, discontinuation, reinitiation, and switching were assessed. To address cohort imbalances, inverse probability of treatment weighting was employed. Logistic regression was used to estimate odds ratio for high adherence. Cox proportional hazard models were used to estimate hazard ratio for non-persistence, discontinuation, and switching. Results Overall, 411 IXE and 780 SEC users were included. After weighting, IXE users had significantly higher rate of high treatment adherence (42% vs. 35%, p = 0.019), higher persistence rate (44.9% vs. 36.9%, p = 0.007), lower discontinuation rate (48.4% vs. 56.0%, p = 0.012), and lower switching rate (26.6% vs. 34.0%, p = 0.009) compared with SEC users. After multivariable adjustment, compared with SEC, IXE use was associated with 36% higher odds of high treatment adherence (OR 1.36, 95% CI 1.05–1.74), 20% lower risk of treatment non-persistence (HR 0.80, 95% CI 0.68–0.93), 19% lower risk of discontinuation (HR 0.81, 95% CI 0.68–0.96), and 25% lower risk of switching (HR 0.75, 95% CI 0.60–0.93). Conclusion This study suggests that IXE treatment is associated with significantly higher adherence rates and significantly lower non-persistence, discontinuation, and switching compared with SEC treatment.

To compare drug survival of ixekizumab to other IL‐17 inhibitors (IL‐17i) and TNF inhibitors (TNFi) among patients with psoriasis (PsO) in a real‐world setting. Participants included adult PsO patients enrolled in the Corrona Psoriasis Registry who initiated ixekizumab, TNFi, or other IL‐17i between 16 March 2016 to 10 August 2019 and completed ≥1 follow‐up visit. Multivariable adjusted hazard ratios (HR) were calculated to estimate the risk for drug discontinuation in the ixekizumab group relative to the other drugs. Among the 1604 drug initiations, 552 initiated ixekizumab, 450 initiated TNFi, and 602 initiated other IL‐17i. Mean age was 51 years, 49% were women, and 52% were obese (BMI > 30). Ixekizumab patients had a higher proportion of patients with PASI >12 at drug initiation (24%) than TNFi (15%) and other IL‐17i (19%). Over a median of 11 months of follow‐up, 723/1604 (45%) drug discontinuations occurred. Persistence of ixekizumab, TNFi, and other IL‐17i at 24‐months were 68%, 33%, and 46%, among biologic‐naïve patients (n = 543), and 46%, 23%, and 36%, for biologic‐experienced patients (n = 1061), respectively. Ixekizumab patients had a 64% lower risk of discontinuation vs TNFi (HR = 0.36; 95% CI 0.27‐0.47) and a 31% lower risk vs other IL‐17i (HR = 0.69, 95% CI 0.55‐0.87) after adjustment for biologic experience and other covariates. HRs were similar when limited to patients with moderate‐to‐severe PsO (BSA > 3, PASI > 3, and IGA > 1, n = 1076) at initiation. In our study of real‐world patients with PsO, initiators of ixekizumab had more prolonged drug survival than both initiators of TNFi and other IL‐17i up to 2 years of follow‐up.

Purpose Proper adherence and persistence to medications are crucial for better quality of life and improved outcomes in rheumatoid arthritis (RA), psoriasis (PsO), and psoriatic arthritis (PsA). We systematically describe current adherence and persistence patterns for RA, PsO, and PsA, with a focus on biologics and identifying factors associated with adherence and persistence. Patients and methods Using various databases, a systematic literature review of US-based studies published from 2000 to 2015 on medication adherence and persistence to biologics and associated factors was conducted among patients with RA, PsO, and PsA. Results Using the medication possession ratio or the percentage of days covered >80%, RA and PsO adherence rates for etanercept, adalimumab, and infliximab ranged from 16% to 73%, 21% to 70%, and 38% to 81%, respectively. Using the criteria of a ≥45-day gap, RA persistence rates for etanercept, adalimumab, and infliximab ranged from 46% to 89%, 42% to 94%, and 41% to 76%, respectively. In PsO, persistence rates for etanercept and adalimumab ranged from 34% to 50% and 50% to 62%, respectively. Similar persistence rates were observed in PsA. Experienced biologics users showed better adherence and persistence. Younger age, female gender, higher out-of-pocket costs, greater disease severity, and more comorbidities were associated with lower adherence and persistence rates. Qualitative surveys revealed that nonpersistence was partly due to perceived ineffectiveness and safety/tolerability concerns. Conclusion Biologic adherence and persistence rates in RA, PsO, and PsA in the United States were low, with significant opportunity for improvement. Various factors - including decrease in disease severity; reduction of comorbidities; lower out-of-pocket costs; refilling at specialty pharmacies; and awareness of drug effectiveness, safety, and tolerability - can inform targeted approaches to improve these rates.

As more biologics become available for the treatment of psoriasis (PsO), there is a lack of direct comparisons of health care costs between patients who are treated by different medications, including ixekizumab (IXE), secukinumab (SEC), and adalimumab (ADA).To compare the real-world health care costs of patients with PsO initiating IXE with those of patients initiating either SEC or ADA.Patients diagnosed with PsO between July 1, 2015, and May 31, 2018, were identified from the IBM MarketScan commercial and Medicare databases. Two weighted patient sample sets were constructed based on drug claims between March 1, 2016, and May 31, 2018: IXE versus SEC and IXE versus ADA. Within each sample, the first claim of eligible drugs was set as the index date. Patients were aged ≥ 18 years and had ≥ 12 months of continuous eligibility before and after the index date. Patients with other indications for the index drug in the preperiod or with use of the index drug within 90 days before the index date were excluded. Inverse probability of treatment weighting (IPTW) was employed to balance cohorts. All-cause and PsO-related health care costs per member per month (PMPM) incurred during the 12-month follow-up period were assessed. Monthly PsO-related pharmacy costs were adjusted using drug discount rates published by the Institute for Clinical and Economic Review (ICER). Annual index drug costs were estimated by adjusting for medication possession ratio and ICER discount rates. All costs were weighted by IPTW.Two study samples were identified: 357 IXE users were compared with 763 SEC users, and 388 IXE users were separately compared with 2,578 ADA users. Before weighting, IXE users were demographically and clinically similar to SEC users but were older and had worse health status than ADA users. Cohorts were balanced postweighting. After weighting, mean monthly all-cause health care costs were $7,313 and $6,477 (After adjusting for drug discount programs (through application of ICER discount rate), this real-world study estimated that average monthly PsO-related costs during the first year of treatment were similar between patients treated with IXE compared with those treated with SEC or ADA.Funding for this study was provided to IBM Watson Health by Eli Lilly and Company.

Objectives: To describe ixekizumab treatment patterns, all-cause healthcare utilization, and costs among psoriasis patients. Methods: Adults diagnosed with psoriasis having ≥1 ixekizumab claim were selected from MarketScan® databases between March 01, 2016 and July 31, 2017. Patients were continuously enrolled for ≥6 months prior and ≥3 months after the index date (first ixekizumab claim) and followed until inpatient death, end of enrollment, or end of data. Treatment patterns included persistence, switching, and re-initiation. All-cause utilization and costs were reported per-patient-per-month (PPPM). Results: 801 patients (mean age 49 years; 55.8% male; median follow-up 201 days) were included. Among all patients, 87.4% were persistent (mean (median) duration 86 (75) days) Of the 12.6% of patients who discontinued ixekizumab, 11.9% re-initiated and 6.9% switched treatments. Mean (median) time to switching was 208 (206) days. Mean number of all-cause inpatient admissions and physician office visits PPPM were 0.01 and 0.72, respectively. Mean total cost PPPM was $8,371, of which pharmacy comprised $7,792. Ixekizumab costs, $7,079, occurred primarily during induction and were paid predominantly by health plans ($6,810 [96.2%]). Conclusion: Most (87.4%) ixekizumab users remained persistent during follow-up. Pharmacy was the primary driver of total healthcare costs, with the majority covered by health plans and

ObjectiveTo compare the characteristics of patients with psoriatic arthritis among patient groups stratified by degree of skin and joint involvement, and to evaluate the relationship between skin severity and joint activity.MethodsBody surface area (BSA) and Clinical Disease Activity Index (CDAI) at enrolment were analysed. Patient characteristics were stratified by skin severity and joint activity. Baseline patient characteristics, clinical and disease characteristics and patient-reported outcomes were compared. The strength of the relationship of skin severity and joint activity was evaluated using methods for categorical variables (χ2 test, Cramer’s V) and continuous variables (linear regression).Results1542 adult patients in the Corrona Psoriatic Arthritis/Spondyloarthritis Registry enrolled between 21 May 2013 and 20 September 2016 were analysed. Most patients in the BSA >3%/CDAI moderate/high subgroup had worse clinical and patient-reported outcomes. A significant (pConclusionSkin severity is modestly correlated with joint activity, and patients with higher skin severity are two times more likely to have increased joint involvement. Clinicians need to address both skin severity and joint activity in treatment decisions.

To characterize treatment patterns of psoriasis patients in a large US managed care database.Adults with newly-diagnosed psoriasis were identified from July 3, 2006-August 31, 2014. Patients had continuous enrollment with medical and pharmacy benefits for ≥6 months prior to and ≥1 year following the index date. The index date was the point at which any of the following inclusion criteria were satisfied: first psoriasis diagnosis by a dermatologist, ≥ 2 psoriasis diagnoses ≥30 days apart, or a diagnosis of psoriasis followed by a claim for psoriasis therapy. Of primary interest was to measure and describe the following psoriasis treatment patterns: utilization rates, time to treatment discontinuation, and lines of therapy for various therapeutic classes of pharmacologic therapies.From the 128,308 patients identified, 53% were female, mean ± SD age was 50 ± 16 years, with median 3 years follow-up. Topicals were received by 86% of patients, non-biologic systemics by 13%, biologics by 6%, phototherapy by 5%, and 13% received no psoriasis-related medication. Median time from index to first treatment was 0 days for topical, 6 months for non-biologic systemic, and 6 months for biologic. Of those treated, first-line therapies included topical (95%), non-biologic systemic (4%), and biologic (2%). For those with second-line treatment, non-biologic systemic (71%) and biologic (30%) therapies were more common. The most common treatment pattern was topicals only (83%), while all other patterns comprised5% of the treatment patterns observed.Like other observational studies, limitations to consider when interpreting results include the 6-month pre-index period of no psoriasis or the psoriasis medication claim may not perfectly select only incident user of psoriasis medications, claims-based algorithms may not accurately represent true treatment patterns, absence of over-the-counter medications data, and having no trend analyses over time or between groups.While the majority of patients with psoriasis initiated a pharmacological therapy, a significant portion did not have a claim for any psoriasis medication. Topical treatments are the most commonly used treatments for psoriasis. Non-biologic systemic and biologic therapies were rarely used first line, but became more common in later lines of treatment.

To describe healthcare resource utilization (HCRU) and costs among biologic-treated psoriasis patients in the US, overall and by disease severity.IQVIA PharMetrics Plus administrative claims data were linked with Modernizing Medicine Data Services Electronic Health Record data and used to select adult psoriasis patients between April 1, 2010 and December 31, 2014. Eligible patients were classified by disease severity (mild, moderate, severe) using a hierarchy of available clinical measures. One-year outcomes included all-cause and psoriasis-related outpatient, emergency department, inpatient, and pharmacy HCRU and costs.This study identified 2,130 biologic-treated psoriasis patients: 282 (13%) had mild, 116 (5%) moderate, and 49 (2%) severe disease; 1,683 (79%) could not be classified. The mean age was 47.6 years; 45.4% were female. Relative to mild psoriasis patients, patients with moderate or severe disease had more median all-cause outpatient encounters (28.0 [mild] vs 32.0 [moderate], 36.0 [severe]), more median psoriasis-related outpatient encounters (6.0 [mild] vs 7.5 [moderate], 8.0 [severe]), and a higher proportion of overall claims for medications that were psoriasis-related (28% [mild] vs 37% [moderate], 34% [severe]). Relative to mild psoriasis patients, patients with moderate or severe disease had higher median all-cause total costs ($37.7k [mild] vs $42.3k [moderate], $49.3k [severe]), higher median psoriasis-related total costs ($32.7k [mild] vs $34.9k [moderate], $40.5k [severe]), higher median all-cause pharmacy costs ($33.9k [mild] vs $36.5k [moderate], $36.4k [severe]), and higher median psoriasis-related pharmacy costs ($32.2k [mild] vs $33.9k [moderate], $35.6k [severe]).The assessment of psoriasis disease severity may not have necessarily coincided with the timing of biologic use. The definition of disease severity prevented the assessment of temporality, and may have introduced selection bias.Biologic-treated patients with moderate or severe psoriasis cost the healthcare system more than patients with mild psoriasis, primarily driven by higher pharmacy costs and more outpatient encounters.

In the last decade, student politics and governance of universities in Kenya and in other African countries have undergone a tremendous transformation. The unprecedented expansion and massification of public universities, the introduction of ‘Module 2’ programmes, the admission of private, ‘parallel’ and ‘school-based’ students, and the substantial increase in private universities have impacted on the governance of the institutions and student politics in different ways. In this context, this article explores student involvement in university governance and describes the structure of students’ unions in Kenyan universities in comparison with students exercising ‘comrades’ power’ in universities in Kenya.Keywords: Higher education; student politics; student activism; student unionism; university governance; representation

Rheumatic heart disease (RHD) is a preventable non-communicable condition that disproportionately affects the world's poorest and most vulnerable. The World Heart Federation Roadmap for improved RHD control is a resource designed to help a variety of stakeholders raise the profile of RHD nationally and globally, and provide a framework to guide and support the strengthening of national, regional and global RHD control efforts. The Roadmap identifies the barriers that limit access to and uptake of proven interventions for the prevention and control of RHD. It also highlights a variety of established and promising solutions that may be used to overcome these barriers. As a general guide, the Roadmap is meant to serve as the foundation for the development of tailored plans of action to improve RHD control in specific contexts.

Drug bio screening for potential anti-diabetics is scientifically motivated by the desire to discover newer, safer and affordable drugs that complement conventional strategies for management of diabetes. Urtica dioica grows naturally in many parts of Africa with a wide variety use in traditional medicine and diet. However, scientific validation for use of U. dioica has not been done for anti-diabetic activity. The aim of the study was to determine the antidiabetic effects of aqueous extracts of U. dioica in alloxan induced mice and the safety of U. dioica on mice models. The plant extracts were administered orally at doses of 25 mg/kg, 100 mg/kg, 200 mg/kg and 300 mg/kg which is the common route used in traditional herbal medicine administration. Evaluation for toxicity was determined at a dose of 1000 mg/kg body weight aqueous extracts of U. dioica. The results from the study indicated that the plant extracts exhibited insulin mimetic anti-diabetic activity. Evaluation for toxicity also indicated that a dose of 1000 mg/kg bw preserved the integrity of liver, kidney and lipid profiles for biochemical markers. Moreover, there was no significant change in the hematological and leucocyte counts. There was no significant change in gross body weight, organ body weight and histopathological changes on tissues of the body organs in this study. Furthermore, qualitative and quantitative phytochemical screening of aqueous leaf extracts of U. dioica indicated the presence of phenols, alkaloids, flavonoids, tannins and saponins. Various levels of different mineral elements were also recorded. In conclusion, this study confirmed that U. dioica at a dose of 50 mg/kg, 100 mg/kg, 200 mg/kg and 300 mg/kg body weights possessed anti-diabetic activity. It is also safe for use at a dose of 1000 mg/kg body weight. More studies should be explored on the potential anti-diabetic effects using other routes of administration.
