Chronic Kidney Disease among Middle-Aged and Elderly Population: A cross-sectional screening in a Hospital Camp in Varanasi, India

Balloon angioplasty: A promising adjunct to arteriovenous fistula creation compared with hydrostatic dilatation in small-caliber cephalic veins

BACKGROUND

To maintain the patency and longevity of arteriovenous fistula, the availability of a venous segment with adequate diameter is important. In Indian population, many chronic kidney disease patients have poor caliber veins. The study aimed to evaluate the efficacy of hydrostatic dilatation versus Primary balloon angioplasty of small caliber cephalic veins of (≤2.5 mm) preoperatively in terms of patency rate and maturation time of arteriovenous fistula.

METHODS

Patients (n = 80) with an end-stage renal disease requiring arteriovenous access surgery for hemodialysis with small caliber cephalic veins were randomized into two groups, i.e., hydrostatic dilatation and primary balloon angioplasty, each with 40 patients. All patients underwent a thorough clinical examination as well as duplex ultrasound vein mapping of both upper extremities. Patients were followed up for six months and primary patency, maturation time, and complications were noted.

RESULTS

Immediate technical success with good palpable thrill was achieved in 97.5% of patients in the primary balloon angioplasty group and 87.5% in the hydrostatic dilatation group. The fistula maturation time in the primary balloon angioplasty group was 34.41 days and 46.18 days in the hydrostatic dilatation group. In the primary balloon angioplasty group, the primary patency of the fistula was 97.5% and 87.5% in the hydrostatic dilatation group, at six months. The arteriovenous fistula functioning rate was 77.5% in the hydrostatic dilatation group as compared to 92.5% in the primary balloon angioplasty group at six months. The incidence of surgical site infection was 5% in the primary balloon angioplasty group as compared to 10% in the hydrostatic dilatation group.

CONCLUSION

Primary balloon angioplasty of small caliber cephalic veins (≤2.5 mm) performed prior to arteriovenous fistula creation for hemodialysis is a beneficial procedure.

Community-based screening to determine the prevalence, health and nutritional status of patients with CKD in rural and peri-urban Bangladesh

Background:

Studies have labelled chronic kidney disease (CKD) among the adult population in urban Bangladesh. To address knowledge gaps on CKD, we aimed to generate data on prevalence, health and nutrition of CKD individuals living in rural and peri-urban Bangladesh.

Methods:

Participants were recruited from the Mirzapur Demographic Surveillance System by age-stratified random sampling. We screened participants by measuring serum creatinine and urine albumin to creatinine ratio, and collected socio-demographic, lifestyles and health information (phase I). After 3 months (phase II), we repeated the urine and blood tests as per the Kidney Disease Outcomes Quality Initiative guidelines. The glomerular filtration rate was calculated using the CKD Epidemiology Collaboration equation.

Results:

Among 928 participants, 872 completed the study. In phase I, probable CKD cases were 281 (32.2%); in phase II, confirmed cases were 192 (22.0%) (stage 1, 4.0%; stage 2, 11.8%; stage 3, 5.5%; stage 4, 0.6%; stage 5, 0.1%). In multivariable analysis, associated factors for prevalent CKD included aged ⩾60 years [adjusted odds ratio (aOR) 5.02; 95% confidence interval (CI) 1.85–13.65], hypertension (aOR 3.08; 95% CI 2.07–4.59), diabetes (aOR 2.52; 95% CI 1.60–3.96), presence of red blood cell in urine (aOR 3.20; 95% CI 1.71–5.98) and anemia (aOR 2.50; 95% CI 1.63–3.84).

Conclusions:

This is the first ever research on CKD prevalence in rural and peri-urban Bangladesh and recorded about 22%, which is higher than urban settings. Monitoring systems are needed to evaluate the overall burden and to mitigate risk factors with an emphasis on the rural and peri-urban population.

Stretching the boundaries: suitability of an arteriovenous fistula in elderly patients on hemodialysis-a northern India experience

PURPOSE

Considering various factors, such as multiple co-morbidities, unsuitable vessels for access creation, non-maturation, vascular calcifications, the outcome of arteriovenous fistula (AVF) in the elderly population, may not be similar to the younger people. Our study aims to analyze the outcomes of AVF in elderly patients (> 65 year).

METHODS

It was a prospective observational study. Patients of more than 65 years of age in whom AVF was created from January 2012 to December 2015 were included in the study. These patients were followed up for 4 years. The primary endpoint of our study was to assess primary and secondary patency rates.

RESULTS

A total of 450 AVFs were included in the study. The mean age was 68.5 years. The most common site of AVF was radiocephalic (RCAVF) in 70% (n = 315), brachiocephalic (BCAVF) in 24% (n = 108) and basilic vein transposition (BVT) in 6% (n = 27). At 48 months, the primary patency rate of RCAVF, BCAVF, and BVT was 55%, 61.6%, and 60.4%, respectively. The commonest cause of access failure was thrombosis followed by non-maturation.

CONCLUSION

AVF remains the preferred vascular access for hemodialysis even in the elderly population. Failure to mature and thrombosis continue to be a concern with AVF. Location of the AV access does not seem to impact the long-term patency.

Current Management Strategies of Chronic Kidney Disease in Resource-Limited Countries

The incidence and prevalence of chronic kidney disease (CKD) and kidney failure continues to increase worldwide, especially in resource-limited countries. Many countries in this category already have a massive burden of communicable diseases, as well as socio-economic and socio-demographic challenges. The rising CKD burden and exorbitant economic cost associated with treatment are mainly responsible for the alarming mortality rate associated with kidney disease in these regions. There is often poor risk factor (diabetes and hypertension) and CKD awareness in these countries and limited availability and affordability of treatment options. Given these observations, early disease detection and preventive measures remain the best options for disease management in resource-limited settings. Primary, secondary and tertiary preventive strategies need to be enhanced and should particularly include measures to increase awareness, regular assessment to detect hypertension, diabetes and albuminuria, options for early referral of identified patients to a nephrologist and options for conservative kidney management where kidney replacement therapies may not be available or indicated. Much is still needed to be done by governments in these regions, especially regarding healthcare funding, improving the primary healthcare systems and enhancing non-communicable disease detection and treatment programs as these will have effects on kidney care in these regions.
