The hidden financial catastrophe of chronic kidney disease under universal coverage and Thai "Peritoneal Dialysis First Policy".

Objective: Universal health coverage can decrease the magnitude of the individual patient's financial burden of chronic kidney disease (CKD), but the residual financial hardship from the patients' perspective has not been well-studied in low and middle-income countries (LMICs). This study aimed to evaluate the residual financial burden in patients with CKD stage 3 to dialysis in the "PD First Policy" under Universal Coverage Scheme (UCS) in Thailand. Methods: This multicenter nationwide cross-sectional study in Thailand enrolled 1,224 patients with pre-dialysis CKD, hemodialysis (HD), and peritoneal dialysis (PD) covered by UCS and other health schemes for employees and civil servants. We interviewed patients to estimate the proportion with catastrophic health expenditure (CHE) and medical impoverishment. The risk factors associated with CHE were analyzed by multivariable logistic regression. Results: Under UCS, the total out-of-pocket expenditure in HD was over two times higher than PD and nearly six times higher than CKD stages 3-4. HD suffered significantly more CHE and medical impoverishment than PD and pre-dialysis CKD [CHE: 8.5, 9.3, 19.5, 50.0% (p < 0.001) and medical impoverishment: 8.0, 3.1, 11.5, 31.6% (p < 0.001) for CKD Stages 3-4, Stage 5, PD, and HD, respectively]. In the poorest quintile of UCS, medical impoverishment was present in all HD and two-thirds of PD patients. Travel cost was the main driver of CHE in HD. In UCS, the adjusted risk of CHE increased in PD and HD (OR: 3.5 and 16.3, respectively) compared to CKD stage 3. Conclusions: Despite universal coverage, the residual financial burden remained high in patients with kidney failure. CHE was considerably lower in PD than HD, although the rates remained alarmingly high in the poor. The "PD First' program" could serve as a model for other LMICs. However, strategies to minimize financial distress should be further developed, especially for the poor.

Membranous Nephropathy following Full-Dose of Inactivated SARS-CoV-2 Virus Vaccination: A Case Report and Literature Review.

Vaccination against the SARS-CoV-2 virus (COVID-19) has proven to be the most effective measure to prevent the spread and reduce infection severity. A case report of de novo membranous nephropathy (MN) following immunization with inactivated virus vaccine (CoronaVac®, Sinovac Biotech) is presented here. A 53-year-old man presented with a sudden onset of leg edema a week after receiving an inactivated virus vaccine and a relapse of nephrotic syndrome (NS) with acute kidney injury (AKI) after a booster dose. Screening for serum anti-phospholipase A2 receptor antibody and secondary causes of MN were negative. Kidney biopsy revealed an early MN pattern with focal spike formation, whilst numerous subepithelial electron-dense deposits and a few small deposits in the mesangial area were observed through electron microscopy. A short course of steroids and oral cyclophosphamide was prescribed, resulting in the complete remission of NS and AKI. MN following SARS-CoV-2 vaccination should call for medical importance. Awareness of the association between vaccination and MN should be kept in mind to avoid unnecessary treatment with long-term immunosuppressive agents.

Health-Related Problems and Drivers of Health-Related Quality of Life Among Community-Dwelling Older Adults.

Purpose: The aims of this study were to explore prevalence of health-related problems and identify factors associated with health-related quality of life (HRQOL) among community-dwelling older adults (CDOAs) in rural Thailand. Methods: A total of 384 CDOAs with mean age of 71 years (SD = 7.6) were recruited. The Thai Ministry of Public Health's comprehensive geriatric assessment (CGA) was used to measure the CDOAs' health conditions in the primary care unit of community hospitals. HRQOL of the participants was assessed by using the EQ-5D questionnaire. Results: The results showed that the most common health-related problems were risk of glaucoma (89.6%) and hypertension (64.6%). The HRQOL were predicted by the incidence of falls (ß = -0.076, P < .001), Timed Up and Go Test (ß = -0.087, P < .001), and age (ß = -0.667, P = .002). Discussion: This study highlighted the need to incorporate CGA in family practice, which included risk of falls assessment by measuring TUG test, fall prevention, and to provide resources for caring older adults at home which ultimately will improve CDOAs' quality of life.

Hyperparathyroidism and increased fractional excretion of phosphate predict allograft loss in long-term kidney transplant recipients.

BACKGROUND: After kidney transplantation, fibroblast growth factor-23 (FGF-23) normally returns to baseline within 1 year whereas hyperparathyroidism persists in most kidney transplant (KT) recipients. As a result, serum phosphate remains relatively low in association with increased serum calcium and urinary phosphate excretion when compared to chronic kidney disease patients. The relationship between mineral metabolism and outcomes in long-term KT recipients has not been extensively studied. This study investigated whether the alteration in mineral metabolism influenced graft survival in long-term KT recipients. METHODS: This study included 273 KT recipients after 1 year of transplantation. Mineral parameters were obtained at the time of enrolment and patients were followed prospectively for an average of 71 months. RESULTS: Graft loss (death-censored) occurred in 41 (15%) patients. In univariate analysis, deceased donor transplantation, decreased serum albumin and estimated glomerular filtration rate, increased serum phosphate, parathyroid hormone (PTH), FGF-23 and fractional excretion of phosphate (FePi) predicted future allograft loss. After adjustments for cardiovascular disease risk factors, donor type, dialysis vintage, serum albumin and allograft function, only increased PTH and FePi remained associated with the outcome. Relationships between increased serum phosphate and FGF-23 with graft survival were lost after adjustments. Adjusted survival curves revealed the association between PTH > 90 pg/mL and FePi > 20% with worse graft survival. CONCLUSIONS: Hyperparathyroidism and increased FePi predicted allograft loss in long-term KT recipients.

Renal phosphate loss in long-term kidney transplantation.

BACKGROUND AND OBJECTIVES: Renal phosphate wasting occurs early postkidney transplantation as a result of an accumulation of parathyroid hormone and fibroblast growth factor 23 from the CKD period. Serum phosphate, parathyroid hormone, and fibroblast growth factor 23 return to baseline 1 year postkidney transplantation. What happens beyond this period is unknown. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Mineral parameters were obtained from 229 kidney transplant recipients at least 1 year posttransplantation; 46 normal subjects and 202 CKD patients with similar GFR served as controls. Factors associated with phosphate metabolism were analyzed. RESULTS: Despite the reduced graft function, most kidney transplant recipients had lower serum phosphate than normal subjects accompanied by renal phosphate loss. Fibroblast growth factor 23 was mostly lower or comparable with normal subjects, whereas parathyroid hormone was elevated in most patients. Hyperparathyroidism is also more common among kidney transplant recipients compared with CKD patients. Both parathyroid hormone and fibroblast growth factor 23 showed relationships with renal phosphate excretion, but only parathyroid hormone displayed an independent association. Parathyroid hormone showed the highest area under the curve in predicting renal phosphate leak. When patients were categorized according to parathyroid hormone and fibroblast growth factor 23 levels, only subset of patients with high parathyroid hormone had an increased renal phosphate excretion. CONCLUSIONS: Relatively low serum phosphate from renal phosphate leak continued to present in long-term kidney transplantation. Both parathyroid hormone and fibroblast growth factor 23 participated in renal tubular phosphate handling, but persistent hyperparathyroidism seemed to have a greater influence in this setting.

Acute respiratory failure due to Pneumocystis pneumonia: outcome and prognostic factors.

OBJECTIVES: To examine the outcome and prognostic factors of in-hospital mortality in patients with acute respiratory failure (ARF) caused by Pneumocystis pneumonia (PCP) admitted to a medical intensive care unit. METHODS: A retrospective review was conducted of all patients with ARF from PCP in Ramathibodi Hospital between 2000 and 2006. Patient characteristics, clinical presentation, and laboratory, radiological and microbiological findings, as well as therapy and clinical course were included in the analysis of prognostic factors of death. RESULTS: A total of 14 HIV-infected and 30 otherwise immunosuppressed patients were identified. The overall mortality rate was 63.6%. Logistic regression analysis demonstrated that APACHE II score on day 1 and level of PEEP used on day 3 of respiratory failure were associated with higher hospital mortality. In a comparison between the HIV group and the non-HIV group, the early mortality rate was significantly higher in the HIV group, but late hospital mortality was not different between the two groups. Using a univariate logistic regression model, four parameters were found to be significantly associated with death in the HIV group: sex, APACHE II score on day 1, CMV co-infection, and level of PEEP on day 3 of ARF. In the non-HIV group, corticosteroid use prior to diagnosis of PCP and level of PEEP on day 3 of ARF were found to be the significant parameters. CONCLUSION: The mortality rate in patients with ARF caused by PCP was high. Various variable factors were related to a poor prognosis. For improved survival, multimodality treatments are needed to reduce these risk factors.
