Abstract
INTRODUCTION Nonagenarians constitute a rising percentage of inpatients, with acute kidney injury (AKI) being frequent in this population. Thus, it is important to analyze the clinical characteristics of this demographic and their impact on mortality. METHODS Retrospective study of nonagenarian patients with AKI at a tertiary hospital between 2013 and 2022. Only the latest hospital admission was considered, and patients with incomplete data were excluded. A logistic regression analysis was conducted to define risk factors for mortality. A p-value < 0.05 was considered statistically significant. RESULTS A total of 150 patients were included, with a median age of 93.0 years (91.2-95.0), and males accounting for 42.7% of the sample. Sepsis was the most common cause of AKI (53.3%), followed by dehydration/hypovolemia (17.7%), and heart failure (17.7%). ICU admission occurred in 39.3% of patients, mechanical ventilation in 14.7%, vasopressors use in 22.7% and renal replacement therapy (RRT) in 6.7%. Death occurred in 56.7% of patients. Dehydration/hypovolemia as an etiology of AKI was associated with a lower risk of mortality (OR 0.18; 95% CI 0.04-0.77, p = 0.020). KDIGO stage 3 (OR 3.15; 95% CI 1.17-8.47, p = 0.023), ICU admission (OR 12.27; 95% CI 3.03-49.74, p < 0.001), and oliguria (OR 5.77; 95% CI 1.98-16.85, p = 0.001) were associated with mortality. CONCLUSION AKI nonagenarians had a high mortality rate, with AKI KDIGO stage 3, oliguria, and ICU admission being associated with death.

Abstract
PURPOSE This study was to investigate the association between albumin-corrected anion gap (AG) (ACAG) levels and the risk of acute kidney injury (AKI) in intensive care unit (ICU) patients. METHODS The ICU patients of this retrospective cohort study were collected from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database between 2008 and 2019. ACAG = AG + {4.4 - [albumin (g/dl)]} × 2.5. The incidence of AKI was determined using the Kidney Disease: Improving Global Outcomes (KDIGO) definition. The logistic regression model was used to evaluate the association between ACAG levels and the risk of AKI. Subgroup analyses were applied based on age, gender, mechanical ventilation, vasopressors, the Charlson comorbidity index (CCI), and the Simplified Acute Physiology Score II (SAPS II). RESULTS Totally, 5586 patients were enrolled, of which 1929 patients (34.53%) occurred AKI. The higher levels of ACAG were associated with the risk of AKI in ICU patients, with the odds ratio (OR) value being 1.23 [95% confidence interval (CI): 1.22-1.24, P = 0.005] in ACAG level between 16.5 and 19.5, and OR value being 1.20 (95% CI 1.16-1.24, P = 0.016) in ACAG level > 19.5. A higher ACAG level was associated with a higher risk of AKI in ICU patients aged < 65 years, in ICU patients of female gender, in ICU patients who used mechanical ventilation, in ICU patients who did not use vasopressors, in patients without cardiogenic shock, and in ICU patients with CCI ≥ 2, and SAPS II > 31 (all P < 0.05). CONCLUSION There is an association between ACAG level and the risk of AKI in ICU patients. A higher ACAG value in ICU patients should therefore receive more attention.

Abstract
Background The elderly population in India is expected to increase to 319 million by 2050. Managing critically ill elderly patients in intensive care units (ICUs) is a difficult task. Proper planning and development of healthcare infrastructure are of prime importance to face this challenge. Objectives To study the clinical profile and outcomes of elderly patients admitted to the medical ICUs. Materials and methods A time-bound, prospective observational study on elderly patients admitted to medical ICUs for more than 48 hours was conducted from March 2019 to September 2020. The demographic, biochemical, hematologic, and microbiological data on antibiotic susceptibility patterns on various organisms and procalcitonin (PCT) reports were collected. Acute Physiology and Chronic Health Evaluation II (APACHE II) score was calculated. Various treatment modalities, such as mechanical ventilation, inotropes, hemodialysis, antibiotics, culture report in sepsis patients, and length of ICU stay were collected. Results The age of the patients and the length of their ICU stay were not significantly associated with outcomes. Sepsis and APACHE II scores are significantly associated with outcomes. Receipt of mechanical ventilation, vasopressor support, and hemodialysis are significantly associated with mortality (p < 0.001). Conclusion The patients' ages were not significantly associated with outcomes. The most common cause of death among elderly patients was found to be sepsis, followed by pneumonia. In elderly ICU patients, gram-negative organisms are the most common causative agents in bloodstream infections. The APACHE II score, sepsis, receipt of mechanical ventilation, vasopressor support, and hemodialysis are significantly associated with mortality.

Abstract
INTRODUCTION While patients with diabetes are at higher risk of developing acute kidney injury (AKI), there are few studies on the recurrence of AKI in older adult patients. This study therefore aimed to examine the impact of diabetes on AKI recurrence and long-term outcomes in older male patients. METHODS This retrospective cohort study included older male patients who experienced AKI during hospitalization from July 2007 to August 2011. Medical records of all patients were followed up for 10 years. Patients with AKI were classified into groups with and without diabetes. We analyzed differences in common geriatric comorbidities, AKI recurrence frequency, and severity between the two groups, identified risk factors affecting recurrence frequency, and assessed outcomes. RESULTS Of all 266 patients, 128 had diabetes and 138 did not. The AKI recurrence rate was significantly higher in the group with diabetes (80.5 vs. 66.7%; P = 0.011). There was a significantly higher proportion of AKI caused by infections in patients with diabetes (43.3 vs. 33.2%, P = 0.006). The proportion of patients with an AKI recurrence frequency ≥ 3 was significantly higher in the group with diabetes (44.7 vs. 29.4%, P = 0.027). Diabetes and coronary heart disease were independent risk factors for AKI recurrence (P < 0.05), diabetes control was associated with multiple AKI recurrences (P = 0.016), and no significant difference was found between the groups regarding the 10-year prognosis (P = 0.522). However, a subgroup analysis showed that patients with multiple AKI recurrences within 2 years had the worst survival outcome (P = 0.004). CONCLUSIONS Older male patients with diabetes are prone to AKI recurrence after initial onset of AKI. Diabetes is an independent risk factor for AKI recurrence, and active diabetes control (HbA1c < 7%) may thus reduce the recurrence of AKI and improve the very poor outcomes of patients with multiple recurrences of AKI within 2 years.

Prophylactic Perioperative Terlipressin Therapy for Preventing Acute Kidney Injury in Living Donor Liver Transplant Recipients: A Systematic Review and Meta-Analysis. J Clin Exp Hepatol 2022; 12:417-427. [PMID: 35535072 PMCID: PMC9077193 DOI: 10.1016/j.jceh.2021.06.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Accepted: 06/18/2021] [Indexed: 12/12/2022] Open
Abstract
Background Acute kidney injury (AKI) is common in the perioperative transplant period and is associated with poor outcomes. Few studies reported a reduction in AKI incidence with terlipressin therapy by counteracting the hemodynamic alterations occurring during liver transplantation. However, the effect of terlipressin on posttransplant outcomes has not been systematically reviewed. Methods A comprehensive search of electronic databases was performed. Studies reporting the use of terlipressin in the perioperative period of living donor liver transplantation were included. We expressed the dichotomous outcomes as risk ratio (RR, 95% confidence interval [CI]) using the random effects model. The primary aim was to assess the posttransplant risk of AKI. The secondary aims were to assess the need for renal replacement therapy (RRT), vasopressors, effect on hemodynamics, blood loss during surgery, hospital and intensive care unit (ICU) stay, and in-hospital mortality. Results A total of nine studies reporting 711 patients (309 patients in the terlipressin group and 402 in the control group) were included for analysis. Terlipressin was administered for a mean duration of 53.44 ± 28.61 h postsurgery. The risk of AKI was lower with terlipressin (0.6 [95% CI, 0.44-0.8]; P = 0.001). However, on sensitivity analysis including only four randomized controlled trials (I2 = 0; P = 0.54), the risk of AKI was similar in both the groups (0.7 [0.43-1.09]; P = 0.11). The need for RRT was similar in both the groups (0.75 [0.35-1.56]; P = 0.44). Terlipressin therapy reduced the need for another vasopressor (0.34 [0.25-0.47]; P < 0.001) with a concomitant rise in mean arterial pressure and systemic vascular resistance by 3.2 mm Hg (1.64-4.7; P < 0.001) and 77.64 dyne cm-1.sec-5 (21.27-134; P = 0.007), respectively. Blood loss, duration of hospital/ICU stay, and mortality were similar in both groups. Conclusions Perioperative terlipressin therapy has no clinically relevant benefit.

Abstract
BACKGROUND The increase in life expectancy leads to higher hospitalisation rates in elderly patients. The aim of this work is to study the characteristics of the population over 90 years of age that are admitted due to acute kidney injury (AKI). MATERIAL AND METHODS A cross-sectional study was conducted that included all patients admitted to hospital with AKI in the years 2013 and 2014. Epidemiological characteristics, comorbidity, medication and baseline analytical data were collected, and a comparison was made between patients with age over 90 years-old and the others. RESULTS A total of 1733 patients were included, of whom 264 (15%) were over 90 years-old. A significantly higher proportion of these patients were women. The most frequent cause of AKI in patients older than 90 years was functional (81%) (p < 0.001 compared to other age groups). The main cause of hospital admission was infection. In the group of over 90 years of age, a higher prevalence was found for arterial hypertension (p = 0.005), chronic kidney disease (p = 0.014), congestive heart failure (p = 0.006), and cognitive impairment (p < 0.0001). The baseline glomerular filtration rate by CKD-EPI was lower in the group of patients older than 90 years (p < 0.0001). Patients under 90 years admitted to hospital due to AKI, had a higher prevalence of diabetes mellitus (p < 0.001), dyslipidaemia (p < 0.001), history of neoplasia (p < 0.001), and a higher Barthel index (p < 0.0001). CONCLUSIONS Nonagenarians admitted due to AKI have functional aetiology as the most common factor. These patients have a higher prevalence of hypertension, heart failure, chronic kidney disease, low functional status, and more cognitive impairment.
