A Descriptive Evaluation of Health Literacy and Determinants of COVID-19 Vaccine Acceptance among Patients with IgA Nephropathy with High Vaccine Uptake.

Aims: Shared decision-making regarding COVID-19 vaccination in IgA nephropathy involves the ability to handle health information regarding potential benefits and risk of flare, but few studies have evaluated health literacy in the context of vaccination. We aimed to evaluate the health literacy and COVID-19 vaccination uptake and acceptance in IgA nephropathy. Methods: Single-center cross-sectional study of 126 consecutive patients with IgA nephropathy. Health literacy was assessed using the HLS-EU-47 questionnaire. Determinants of vaccine acceptance such as contextual influences, individual and group influences, and vaccine-specific issues were adapted from the World Health Organization framework. Results: Forty-eight patients (38.1%) with IgAN nephropathy completed the survey between June and August 2021. The participants' median age was 40.5 (31.6, 52.8) years with median disease duration of 2.8 (1.3, 4.3) years. The median general health literacy index was 31.74 (29.88, 35.82) with significantly greater difficulty in the competency of appraising health information and in the domain of disease prevention (p < 0.001). Forty-five patients (93.8%) received at least one dose of COVID-19 vaccine between January and August 2021. Among the 3 unvaccinated patients, 2 intended to receive the vaccination while and 1 did not intend to get vaccinated. There was a high level of trust and belief that their government and healthcare providers had their best interests at heart and that the healthcare providers were honest about the vaccine's risk and benefits, although 31.2% did not understand how the vaccine works and 22.9% believed that there were other ways to prevent infection. Most thought there was adequate safety information, were confident in the system for tracking adverse events and had no issues with access to the vaccine. Conclusion: Participants with IgA nephropathy had high health literacy scores and low vaccine hesitancy. The determinants for vaccine acceptance can potentially guide efforts to optimize vaccination coverage.

Changes in primary glomerulonephritis in Singapore over four decades
.

This review of 3,289 native kidney biopsies over the past four decades in Singapore documents the changing pattern of biopsy-proven glomerulonephritis (GN)from that of a third world country to that of a developed nation. In the 1st decade, mesangial proliferative GN was the most common form of primary GN, similar to the Asian region. In the 2nd decade, the percentage of mesangial proliferative GN decreased, but membranous GN became more common, as was seen in China and Thailand. In the 3rd decade, focal segmental glomerulosclerosis (FSGS) and membranous nephropathy continued to rise, but it was only recently, in the 4th decade, that FSGS prevalence increased dramatically, although membranous nephropathy continues to increase in some Asian countries. In the last decade in Singapore, Malaysia, and Japan, prevalence of IgA nephritis has decreased but remains the most common GN. The percentage of FSGS continues to increase in many countries like in Italy, United States of America, United Kingdom, China, and Malaysia. We surmise that socioeconomic factors play significant roles in the evolution of the renal biopsy pattern.
