    Abstract We performed a descriptive study to characterize effects from COVID-19 among chronic dialysis patients compared with the general population in Argentina during March 2020-February 2021. COVID-19 case-fatality rate of chronic dialysis patients was 10 times the national rate; the age-standardized mortality ratio was 6.8 (95% CI 6.3-7.3).

    Abstract Chronic kidney disease (CKD) represents a major challenge for Latin American (LatAm) because of its epidemic proportions. Therefore, the current status and knowledge of CKD in Latin America is not clearly understood. Moreover, there is a paucity of epidemiologic studies that makes the comparison across the countries even more difficult. To address these gaps, a virtual kidney expert opinion meeting of 14 key opinion leaders from Argentina, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Guatemala, Mexico, and Panama was held in January 2022 to review and discuss the status of CKD in various LatAm regions. The meeting discussed the following: (i) epidemiology, diagnosis, and treatment of CKD, (ii) detection and prevention programs, (iii) clinical guidelines, (iv) state of public policies about diagnosis and management of chronic kidney disease, and (v) role of innovative therapies in the management of CKD. The expert panel emphasized that efforts should be made to implement timely detection programs and early evaluation of kidney function parameters to prevent the development or progression of CKD. Furthermore, the panel discussed the importance of raising awareness among health care professionals; disseminating knowledge to the authorities, the medical community, and the general population about the kidney and cardiovascular benefits of novel therapies; and the need for timely updating of clinical practice guidelines, regulatory policies, and protocols across the region.

    Abstract In June 2009, the World Health Organization declared a novel influenza A, S-OIV (H1N1), pandemic. We observed 44 consecutive patients during the "first wave" of the pandemic. 70.5% of them showed co-morbidities (hypertension, obesity, chronic respiratory diseases, chronic renal disease, diabetes, pregnancy). Serious cases were admitted to the intensive care unit (ICU), particularly those with severe acute respiratory failure. Some of them developed acute kidney injury (AKI) and required renal replacement therapy (RRT). The average time between admission to the ICU and initiation of RRT was 3.16 ± 2.6 days. At initiation of RRT, most patients required mechanical ventilation. No relationship was found with creatinine-kinase levels. Seventy-five percent of the cases were observed during a 3-week period and mortality, related to respiratory failure, doubling of alanine amino transferase and use of inotropics was 81.8%. In conclusion, the H1N1-infected patients who developed RRT-requiring AKI, in the context of multi-organ failure, showed a high mortality rate. Thus, it is mandatory that elaborate strategies aimed at anticipating potential renal complications associated to future pandemics are implemented.

    Abstract Introduction: The presence of chronic allograft nephropathy (CAN) in protocol biopsies is negatively associated with graft survival. Although recent studies have indicated that the resistive index (RI) is a predictor of graft failure, it does not correlate with CAN in stable grafts. We therefore studied the relationship between RI and CAN and examined the predictive value of both parameters on graft outcome.
    Methods: Included were patients transplanted between 1997 and 2002 and who had protocol biopsies and RI determinations. Renal lesions were blindly evaluated according to Banff 97 criteria. Mean glomerular volume, cortical interstitial volume fraction and intimal arterial volume fraction were estimated using a point counting technique. RI was determined before biopsy in at least two different renal locations. The outcome variable was defined as graft failure or a 30% serum creatinine increase between protocol biopsy and last follow-up.
    Results: Eighty-seven patients were included. RI correlated with recipient age (R = 0.52, P < 0.0001), diastolic blood pressure (R = -0.36, P = 0.0006), pulse pressure index (R = 0.27, P = 0.009) and g-score for histological glomerulitis (rho = 0.30, P = 0.0054), but there were no correlations between RI and chronic Banff scores or any morphometric parameter. The presence of CAN (relative risk, 3.5; 95% confidence interval 1.2-10.2; P = 0.02) but not RI was associated with the outcome variable.
    Conclusion: RI was associated with surrogate measures of vascular compliance such as recipient age and pulse pressure index but not with chronic allograft damage, even when it was evaluated by histomorphometry. Our results indicate that histology may be superior to RI in predicting graft function deterioration, at least in patients with stable renal function.
