Prevalence of and Factors Associated with Nephropathy in Diabetic Patients Attending an Outpatient Clinic in Harare, Zimbabwe

Audit of essential knowledge of diabetes in patients with diabetes in Zimbabwe

Introduction

in Zimbabwe, the organized diabetes education in the governmental health care system is limited, but the Diabetes Association has some educational activities in which persons with diabetes can participate. In this study, the purpose was to measure essential knowledge of diabetes and its management in persons with diabetes living in Zimbabwe.

Methods

a cross-sectional descriptive study design was used to audit essential knowledge of diabetes and its management in persons with type 2 diabetes through a survey of 64 persons attending meetings at the Zimbabwe Diabetes Association. Both descriptive and analytic statistical methods were used.

Results

in general respondents have acceptable knowledge of diabetes, whereas their knowledge of glycaemic control is low (45%), likewise their knowledge of how to manage medical treatment when ill. Knowledge concerning lifestyle-related issues was generally low. Respondents had limited knowledge about changes in blood glucose during physical activity (18%) and their knowledge about appropriate food for people with diabetes was low (67%). Most respondents were aware of the importance of regular examinations to avoid long-term complications related to diabetes (>87%) but their knowledge of how to prevent foot complications and perform daily preventive foot care was limited (73 %).

Conclusion

there is limited knowledge of diabetes in Zimbabwean persons with type 2 diabetes even if they have participated in educational activities at the patient associations. This further supports the need for development of education for patients in health care which requires increased competence in the field among health care staff.

Correlation of C-Peptide With Complications Observed in Children and Adolescents With Type 1 Diabetes in Tanzania: A Cross-Sectional Survey

Type 1 diabetes mellitus (T1DM) complications corelate with C-peptide levels. However, the C-Peptide role has not been explored in resource limited countries. This study explored the relationship between C-peptide and complications. A cross-sectional study involving participants aged 0 to 25 years with T1DM in Dar es salaam Tanzania, between 2021 and 2022 was done. Diabetes nephropathy and retinopathy were assessed. About 281 (92.4%) participants were screened, 144 (51.2%) were females. Mean age was 19 ± 6 years. Majority 175 (62.3%) had poor glycemic control (HbA1c) > 10%, and low C-Peptide level 201 (71.5%). Retinopathy was 11.7% and risk for nephropathy was 41.3%. About 13.4% and 41.8% with low C peptide had Retinopathy and high-risk nephropathy respectively. Age at diagnosis, poor glycemic control, low c peptide and duration of diabetes were associated with complications. Further prospective studies are needed to capture when complications set in, so to have better strategies to prevent complications.

Indicators of optimal diabetes care and burden of diabetes complications in Africa: a systematic review and meta-analysis

OBJECTIVE

Contemporary data on the attainment of optimal diabetes treatment goals and the burden of diabetes complications in adult populations with type 2 diabetes in Africa are lacking. We aimed to document the current status of attainment of three key indicators of optimal diabetes care and the prevalence of five diabetes complications in adult African populations with type 2 diabetes.

METHODS

We systematically searched Embase, PubMed and the Cochrane library for published studies from January 2000 to December 2020. Included studies reported any information on the proportion of attainment of optimal glycated haemoglobin (HbA1c), blood pressure (BP) and low-density lipoprotein cholesterol (LDLC) goals and/or prevalence of five diabetes complications (diabetic peripheral neuropathy, retinopathy, nephropathy, foot ulcers and peripheral arterial disease). Random effect model meta-analysis was performed to determine the pooled proportion of attainment of the three treatment goals and the prevalence of five diabetes complications.

RESULTS

In total, 109 studies with a total of 63 890 participants (53.3% being females) were included in the meta-analysis. Most of the studies were conducted in Eastern African countries (n=44, 40.4%). The pooled proportion of attainment of an optimal HbA1c, BP and LDLC goal was 27% (95% CI 24 to 30, I²=94.7%), 38% (95% CI 30 to 46, I²=98.7%) and 42% (95% CI 32 to 52, I²=97.4%), respectively. The pooled prevalence of diabetic peripheral neuropathy, retinopathy, diabetic nephropathy, peripheral arterial disease and foot ulcers was 38% (95% CI 31 to 45, I²=98.2%), 32% (95% CI 28 to 36, I²=98%), 31% (95% CI 22 to 41, I²=99.3%), 19% (95% CI 12 to 25, I²=98.1%) and 11% (95% CI 9 to 14, I²=97.4%), respectively.

CONCLUSION

Attainment of optimal diabetes treatment goals, especially HbA1c, in adult patients with type 2 diabetes in Africa remains a challenge. Diabetes complications, especially diabetic peripheral neuropathy and retinopathy, are highly prevalent in adult populations with type 2 diabetes in Africa.

Perceptions of diabetes patients and their caregivers regarding access to medicine in a severely constrained health system: A qualitative study in Harare, Zimbabwe

Nearly half of all sub-Saharan African countries lack operational Diabetes Mellitus policies. This represents an opportunity to build reliable evidence to underpin such policies when they are eventually developed. Representing the interests of those with the experience of living with the condition in national diabetes policies is important, particularly the interests regarding medicine access, a key pillar in diabetes management. One way to achieve this representation is to publish patient perceptions. Patient perspectives are especially valuable in the context of diabetes in Sub-Saharan Africa, where much of the empirical work has focused on clinical and epidemiological questions. We therefore captured the challenges and suggestions around medicine access articulated by a population of diabetes patients and their caregivers. This was a qualitative interpretivist study based on data from focus group discussions with adult diabetes patients and their caregivers. Eight FGDs of 4-13 participants each whose duration averaged 13.35 minutes were conducted. Participants were recruited from diabetes outpatient clinics at two health facilities in Harare. One site was Parirenyatwa Hospital, the largest public referral and teaching hospital in Zimbabwe. The other was a private for-profit facility. Ethics approval was granted by the Joint Research Ethics Committee for University of Zimbabwe College of Health Sciences and the Parirenyatwa Group of Hospitals (Ref: JREC 295/18). Diabetes patients and their caregivers are interested in affordable access to medicines of acceptable form and quality with minimum effort. Yet, they often find themselves privileging one dimension of access over another e.g. prioritising affordability over acceptability. Based on participants' articulations, a sound diabetes policy should: 1. provide for financial and consumer protections, 2. regulate healthcare business practices and medicine prices, 3. provide for a responsive health workforce attentive to patient problems, 4. accord the same importance to diabetes that is accorded to communicable diseases, 5. decentralize diabetes management to lower levels of care, 6. limit wastage, corruption, bad macro-financial governance and a lack of transparency about how funding for health is used, and 7. provide support to strengthen patients' and caregivers' psychosocial networks. A diabetes policy acceptable to patients is one infused with principles of good governance, fairness, inclusiveness and humanity; characterised by: financial protection and price regulation, consumer protection, equity in the attention accorded to different diseases, decentralized service delivery, inclusion of patient voice in political decision-making, a responsive compassionate health workforce, psychosocial support for patients and their caregivers and allocative efficiency and transparency in public expenditure.

Relationship of serum vitamin D levels with diabetic microvascular complications in patients with type 2 diabetes mellitus

Background:

Vitamin D deficiency has been reported to be associated with diabetic microvascular complications, but previous studies have only focused on the relationship between vitamin D and specific complications. Therefore, we aimed to explore the relationship between vitamin D level and diabetic microvascular complications in general, including diabetic retinopathy (DR), diabetic nephropathy (DN), and diabetic peripheral neuropathy (DPN).

Methods:

This was a cross-sectional study of 815 patients with type 2 diabetes mellitus (T2DM). Clinical information and laboratory results were collected from the medical records. The relationship between vitamin D and the three diabetic microvascular complications was investigated.

Results:

The serum 25-hydroxyvitamin D (25 [OH] D) level of patients with DPN and/or DN was significantly lower than that of T2DM patients without any microvascular complications (P < 0.01). Univariate analysis showed that the 25 (OH) D level was related to DPN and DN, but not DR. After adjustment, the 25 (OH) D level was confirmed to be an independent protective factor for DPN (odds ratio [OR]: 0.968, P = 0.004]) and DN (OR: 0.962, P = 0.006). The prevalence of DPN and DN increased significantly as the serum 25 (OH) D levels decreased. Furthermore, patients with both DPN and DN had the lowest concentration of serum 25 (OH) D (P < 0.001), and the prevalence of macroalbuminuria increased more abruptly than that of microalbuminuria across the 25 (OH) D tertiles. Among the patients with vitamin D insufficiency, those with DPN presented more comorbid macroalbuminuria than those without DPN (15.32% vs. 4.91%; P = 0.001).

Conclusions:

Vitamin D deficiency is independently associated with higher risk of DPN and DN, but not DR, in T2DM patients. Further, it may be a potential predictor for both the occurrence and severity of DPN and DN.

Burden of diabetic kidney disease among persons with type 2 diabetes mellitus registered in a tertiary care center, Puducherry

BACKGROUND & AIMS

To determine burden of diabetic kidney disease (DKD) and estimate yield and number needed to screen (NNS) in a tertiary diabetes care center.

METHODS

DKD was diagnosed if estimated Glomerular Filtration Rate (eGFR) < 60 ml/min/1.73 m² or Urinary Albumin Creatinine Ratio (UACR) ≥30 mg/g in two urine samples.

RESULTS

Of 511 participants, 206 (40%) had DKD. Using both UACR and eGFR, yield and NNS were 39% and three, respectively.

CONCLUSION

Using eGFR alone, yield and NNS to find a case of DKD among consecutive adult (≥18 years age) patients with type 2 diabetes mellitus were 26.4% and 4, respectively.

Incidence of diabetic nephropathy in patients with type 2 diabetes mellitus at a tertiary healthcare setting in Ethiopia

BACKGROUND AND AIMS

Diabetic nephropathy (DN) is a leading cause of morbidity and mortality in diabetic patients representing a huge health and economic burden. Despite the increasing number of patients with Diabetes Mellitus in Ethiopia, the incidence of diabetic nephropathy in patients with DM has not been well established. Therefore, this study aimed to estimate the incidence and predictors of DN in patients with T2DM at tertiary healthcare setting, Ethiopia.

METHODS

An institution based retrospective follow study was conducted from March 1 to April 28, 2019. Kaplan-meier survival curve together with log rank test were used. Cox proportional hazard model was used at 5% level of significance to determine the net effect of each explanatory variable on diabetic nephropathy. An assumption was check by schoenfeld residual test.

RESULTS

The incidence rate of diabetic nephropathy was 3.6% per 100 person-years (95% CI = 2.49-11.47). The median time to develop nephropathy was 100(95% CI, 96.7-107) months. Predictors of diabetic nephropathy were males (AHR: 2.7, 95%CI: 1.39, 5.23), long duration of diabetes (AHR: 1.03, 95%CI: 1.01, 1.06), HbA1c> 7% (AHR: 1.74, 95% CI: 1.67, 3.12), high density lipoprotein (AHR: 0.37, 95% CI: 0.16, 0.83), and mixed anti-diabetic therapy (AHR: 0.07, 95% CI: 0.01, 0.59).

CONCLUSION

The incidence of diabetic nephropathy among T2DM patients was relatively high. Males, longer duration of diabetes, HbA1c, and fasting blood glucose were increase the risk of diabetic nephropathy.

Correlations among Diabetic Microvascular Complications: A Systematic Review and Meta-analysis

Early detection of diabetic microvascular complications is of great significance for disease prognosis. This systematic review and meta-analysis aimed to investigate the correlation among diabetic microvascular complications which may indicate the importance of screening for other complications in the presence of one disorder. PubMed, Embase, and the Cochrane Library were searched and a total of 26 cross-sectional studies met our inclusion criteria. Diabetic retinopathy (DR) had a proven risk association with diabetic kidney disease (DKD) [odds ratio (OR): 4.64, 95% confidence interval (CI): 2.47-8.75, p < 0.01], while DKD also related to DR (OR: 2.37, 95% CI: 1.79-3.15, p < 0.01). In addition, DR was associated with diabetic neuropathy (DN) (OR: 2.22, 95% CI: 1.70-2.90, p < 0.01), and DN was related to DR (OR: 1.73, 95% CI: 1.19-2.51, p < 0.01). However, the risk correlation between DKD and DN was not definite. Therefore, regular screening for the other two microvascular complications in the case of one complication makes sense, especially for patients with DR. The secondary results presented some physical conditions and comorbidities which were correlated with these three complications and thus should be paid more attention.

Diabetic nephropathy and hypertension in diabetes patients of sub-Saharan countries: a systematic review and meta-analysis

OBJECTIVE

This meta-analysis was undertaken to estimate the prevalence of diabetic nephropathy and its association with hypertension in diabetics of sub-Saharan African countries.

RESULTS

A total of 27 studies were included for the meta-analysis. The pooled overall prevalence of diabetic nephropathy was 35.3 (95% CI 27.46-43.14). In sub-group analyses by types of diabetes and regions, for instance, the prevalence was 41.4% (95% CI 32.2-50.58%) in type-2 diabetes mellitus and 29.7% (95% CI 14.3-45.1%) in Eastern Africa. Pooled point estimates from included studies revealed an increased risk of diabetic nephropathy with hypertension compared to without hypertension (OR = 1.67, 95% CI 1.31, 2.14). Diabetic nephropathy is a common complication in diabetic patients. Diabetic nephropathy complication is significantly higher in hypertensive patients. A preventive strategy should be adopted or planned to reduce diabetes mellitus and its complication of neuropathy, particularly in hypertensive.

Mechanistic Insight and Management of Diabetic Nephropathy: Recent Progress and Future Perspective

Diabetic nephropathy (DN) is the most serious microvascular complication of diabetes and the largest single cause of end-stage renal disease (ESRD) in many developed countries. DN is also associated with an increased cardiovascular mortality. It occurs as a result of interaction between both genetic and environmental factors. Hyperglycemia, hypertension, and genetic predisposition are the major risk factors. However, the exact mechanisms of DN are unclear. Despite the benefits derived from strict control of glucose and blood pressure, as well as inhibition of renin-angiotensin-aldosterone system, many patients continue to enter into ESRD. Thus, there is urgent need for improving mechanistic understanding of DN and then developing new and effective therapeutic approaches to delay the progression of DN. This review focuses on recent progress and future perspective about mechanistic insight and management of DN. Some preclinical relevant studies are highlighted and new perspectives of traditional Chinese medicine (TCM) for delaying DN progression are discussed in detail. These findings strengthen the therapeutic rationale for TCM in the treatment of DN and also provide new insights into the development of novel drugs for the prevention of DN. However, feasibility and safety of these therapeutic approaches and the clinical applicability of TCM in human DN need to be further investigated.
