Association between familial aggregation of chronic kidney disease and its incidence and progression

Genetic Assessment of Living Kidney Transplant Donors: A Survey of Canadian Practices

Background

Kidney failure is a prevalent condition with tendency for familial clustering in up to 27% of the affected individuals. Living kidney donor (LKD) transplantation is the optimal treatment option; however, in Canada, more than 45% of LKDs are biologically related to their recipients which subjects recipients to worse graft survival and donors to higher future risk of kidney failure. Although not fully understood, this observation could be partially explained by genetic predisposition to kidney diseases. Genetic testing of potential LKDs may improve risk assessment and inform the safety of donation. The strategies to evaluate these donors are still evolving. In Canada, little is known about the practice of assessing for genetic conditions among LKDs.

Aim

The aim was to examine the Canadian practices regarding LKDs genetic assessment.

Methods

Questionnaires were sent to 23 Canadian adult transplant centers to examine their protocols for LKDs genetic assessment.

Design

The questionnaire comprised of 10 sections and 21 questions including case scenarios of different LKD encounters. Major domains of the survey addressed general demographics, information sharing practices, effect of mode of inheritance on candidacy decision, having a policy for LKD genetic evaluation, and case scenarios covering the following conditions: autosomal dominant polycystic kidney disease (ADPKD), Alport syndrome, Fabry disease, familial focal and segmental glomerulosclerosis (FSGS), atypical hemolytic uremic syndrome (aHUS), autosomal dominant tubulointerstitial kidney disease (ADTKD), sickle cell, and apolipoprotein L1 mutation (APOL1).

Participants

The questionnaire was sent to the living-donor assessment committee representative (nephrologist) in adult and pediatric kidney transplant centers across Canada.

Results

In total, 16 of 23 Canadian centers responded to the survey. Of the 8 surveyed genetic conditions, ADPKD, Alport syndrome, and aHUS were the most frequently encountered. More centers have specific policies for donor evaluation for ADPKD (25%) and aHUS (21.4%) vs none to very few for other genetic conditions. The most cited guidelines are Kidney Disease Improving Global Outcomes (KDIGO), Canadian Society of Nephrology/Canadian Society of Transplantation (CSN/CST), and the Canadian Blood Services' Kidney Paired Donation Protocol.

Conclusions

Canadian transplant centers follow a case-by-case approach rather than a standard protocol for genetic assessment of LKDs given that current guideline recommendations are based on expert opinion due to a lack of a reliable body of evidence. With the expected rise in utilization of the increasingly available genetic testing, early multidisciplinary assessment including medical geneticists has the potential to improve personalized management. Studies examining long-term donor and graft outcomes are needed to construct the basis for evidence-based recommendations and inform the safety of donations.

Prevalence of chronic kidney disease and associated factors among adult diabetic patients: a hospital-based cross-sectional study

Background

Chronic kidney disease (CKD) has a significant impact on public health with a high morbidity and death rate. Most diabetic patients, in the course of their lives, develop diabetic kidney disease. In the least developed nations, its size is outstripping itself. This study aimed to determine the prevalence of chronic kidney disease and associated factors among adult diabetic patients.

Methods

A hospital-based cross-sectional study was conducted on 328 adult diabetic patients from 1 December 2023 to 4 April 2024 at the Ayder Comprehensive Specialized Hospital, northern Ethiopia. A systematic random sampling method was utilized to select the study participants. Pretested structured questionnaires were used to collect sociodemographic, economic, and behavioral/lifestyle factors. Medical records were also reviewed to collect clinical data. Creatinine analysis was performed by kinetic alkaline picrate method and Chronic Kidney Disease Epidemiology Collaboration 2021 equation was used to calculate the glomerular filtration rate from the serum creatinine, age, and sex. Proteinuria was determined by using the dipstick semiquantitative method. Data were entered and analyzed using SPSS version 29. A variable with a p-value of <0.25 in bivariate logistic regression analyses was analyzed in multivariate logistic regression to identify the associated factors. In multivariable logistic regression, a variable was deemed statistically significant if it had a p-value <0.05. Associations were presented as odds ratio (OR) along with 95% confidence intervals (CIs).

Results

The prevalence of chronic kidney diseases in adult diabetic patients was 26.5% (95% CI, 21.8%-31.7%). About 5.2%, 12.5%, 7.3%, 0.9%, and 0.6% had stage 1-5 chronic kidney diseases, respectively. Hypertension [adjusted OR (AOR) = 2.390; 95% CI, 1.394-4.099, p = 0.002], >10-year duration of diabetes (AOR = 2.585; 95% CI, 2.321-5.807; p = 0.001), and family history of kidney diseases (AOR = 2.884; 95% CI, 1.338-6.218; p = 0.007) were associated factors of chronic kidney diseases.

Conclusions

The study revealed that one in four diabetic patients had chronic kidney disease. Special attention should be given to patients with family history of CKD, long duration on diabetes, and concomitant hypertension.

Prevalence of Chronic Kidney Disease in a High-Risk Population in Urban Lahore, Pakistan: A Cross-sectional Study

Background Chronic kidney disease (CKD) is a globally increasing health concern, and there is a growing focus on early screening and prevention efforts. However, the availability of data on CKD prevalence in Pakistan, particularly in the urban area of Lahore district, is limited. The objective of the Kidney Early Evaluation Program (KEEP) Lahore was to assess the prevalence of CKD in a high-risk population residing in the urban area of Lahore, Pakistan. Methods A cross-sectional study was conducted involving 254 participants, who were over 18 years old and belonged to a high-risk population according to the pre-defined operational definitions. The participants were randomly selected from various towns in Lahore. Screening camps were set up to measure serum creatinine levels and urinary albumin to creatinine ratio (UACR), and then the estimated glomerular filtration rate (eGFR) was calculated using the CKD Epidemiology Collaboration 2021 (CKD EPI) equation. Results Out of the total 254 participants, a diagnosis of CKD was made in 62 (24.2%) individuals. Significant associations were found between CKD and risk factors including hypertension, diabetes, family history of CKD, ischemic heart disease (IHD) or congestive heart failure (CHF), intake of painkillers, and herbal medicines. However, no association was found between obesity (BMI ≥ 30) and CKD. Participants diagnosed with CKD had a mean age of 49.9 years and a mean serum creatinine level of 1.2 mg/dL, while non-CKD participants had a mean age of 43.7 years and a mean serum creatinine level of 0.7 mg/dL. Conclusion Our study revealed that CKD was prevalent in about one-fourth of the participants from the high-risk population of Lahore, indicating a high prevalence of the disease within society. Moreover, hypertension, diabetes, family history of CKD, heart disease, painkillers, and the use of herbal medicines were all significantly linked to CKD in the surveyed sample population.

Out of sight: chronic kidney diseases among diabetic patients attending care and follow up. Findings from pastoralist health facilities of Southern Ethiopia

Background

In Ethiopia, the prevalence of chronic kidney disease (CKD) among the adult population ranges to 19.1%. The disease's impact has increased in low-resource settings due to a lack of knowledge about the condition and its risk factors. Diabetes is one of the numerous causes of CKD. Despite this, little was known in Ethiopia, particularly in the study area. This study aimed to identify the determinants of CKD among diabetic patients enrolled in care and follow up at pastoralist health facility of Jinka General Hospital (JGH), Southern Ethiopia, 2023.

Methods

An institutional-based cross-sectional study design was conducted among 626 diabetic patients recruited through a systematic random sampling. Data was collected using a structured interviewer-administered questionnaire and entered into Epi data version 7.2 and then exported to the Statistical Package for Social Sciences (SPSS) version 25 for further analysis. Bivariate and multivariate logistic regression analyses were conducted to find eligible variables for the later analysis. Variables with p < 0.25 at bivariate logistic regression were selected for multivariate logistic regression analysis. The variables with p < 0.05 at the multivariate analysis were taken as statically significant in the final model.

Results

The prevalence of CKD was 2.7% (95% CI: 1.12-6.01%). Place of residence (AOR: 4.84; 95% CI: 1.51-15.40), presence of hypertension (AOR: 5.69; 95% CI: 1.58-20.51) and family history of CKD (AOR: 6.20; 95% CI: 1.40-15.49) were factors associated with CKD among diabetes patients.

Conclusion

The prevalence found in this study was low when compared with the local studies. Provision of health education to diabetic patients on preventative measures such as physical exercise is cost-effective approach. Factors associated with CKD among diabetics can be significantly mitigated by strengthening the existing NCDs prevention packages in the study area particularly and in Ethiopia generally.

Leading Causes of Chronic Kidney Disease Among Dialysis Patients in Al-Baha Region, Saudi Arabia

Introduction Chronic kidney disease (CKD) and its progression to end-stage renal disease (ESRD) represent a growing health concern globally, with hypertension and diabetes commonly identified as primary etiological factors. This study evaluates the demographic and health profiles of individuals undergoing dialysis treatment in the Al-Baha region of Saudi Arabia, aiming to identify the predominant causes of ESRD and the associated socioeconomic and healthcare-related factors. Methodology This cross-sectional study analyzed data from patients receiving dialysis in Al-Baha. We assessed variables including etiology of ESRD, demographic data, presence of comorbid conditions, initial symptoms, and pre-dialysis health care engagement. Statistical analysis focused on the prevalence and correlations between the different variables and ESRD. The study also examined patients' educational background and employment status to ascertain ESRD's socioeconomic impact. Results The study found hypertension and diabetes as the leading causes of ESRD. Unknown etiologies accounted for 10.1% of cases, highlighting an area for further research. Notably, coronavirus disease 2019 (COVID-19) and cardiogenic shock emerged as potential new contributors, each representing 1.7% of cases. Most patients resided in urban areas, with the largest age group being 46 to 55 years. Men had a higher prevalence of ESRD than women. Low educational attainment was significant among patients, and unemployment due to ESRD was prevalent, pointing towards the need for vocational support. Clinical findings revealed late referrals to nephrologists, with a substantial proportion of diagnoses occurring in emergency settings. Family history suggested a higher-than-expected genetic component of CKD in the region. Conclusion The study confirms hypertension and diabetes as principal contributors to ESRD in Al-Baha while also pointing to the emergence of COVID-19 as a potential risk factor. Socioeconomic factors, including educational and employment status, are critical to patient management and outcomes. The high percentage of unknown etiologies and familial CKD prevalence warrants additional research. Improving early detection, enhancing patient education, and fostering timely nephrology consultations could mitigate the progression to ESRD and enhance patient quality of life.
