RESUMO
(1) Background: We aimed to investigate the outcomes of human leukocyte antigen (HLA)-incompatible transplantation for patients who received desensitization with intravenous immunoglobulins (IVIg), plasmapheresis, and rituximab. (2) Methods: A comprehensive search of multiple electronic databases to identify studies that utilized desensitization was conducted. The random-effects model was used to calculate the pooled rates and the 95% confidence interval (CI). (3) Results: A total of 1517 studies were initially identified. From these, 16 studies met the inclusion criteria, encompassing 459 patients, with a mean age of 45 years, of whom 40.8% were male. CDC crossmatch was positive in 68.3% (95% CI: 43.5-85.8; I2 87%), and 89.4% (95% CI: 53.4-98.4%; I2 89.8%) underwent living-donor transplantation. The 1-year graft survival pooled rate was 88.9% (95% CI: 84.8-92; I2 0%) and the 5-year graft survival rate was 86.1% (95% CI: 81.2-89.9; I2 0%). The 1-year patient survival rate was 94.2% (95% CI: 91-96.3; I2 0%), and the 5-year patient survival rate was 88.9% (95% CI: 83.5-92.7%; I2 7.7%). The rate of antibody-mediated rejection was 37.7% (95% CI: 25-52.3; I2 80.3%), and the rate of acute cell-mediated rejection was 15.1% (95% CI: 9.1-24; I2 55%). (4) Conclusions: Graft and patient survival are favorable in highly sensitized patients who undergo desensitization using IVIg, plasmapheresis, and rituximab for HLA-incompatible transplantation.
RESUMO
Drug-induced acute interstitial nephritis (AIN) presents as acute kidney injury (AKI) with the use of certain offending drugs. Antibiotics, such as ß-lactams, trimethoprim-sulfamethoxazole, fluoroquinolones, and rifampin, account for up to 50% of drug-induced AIN cases. The onset of drug-induced AIN following drug exposure usually ranges from few days to several weeks or months. We present a patient with lupus who had rapid decline in renal function with a single dose of vancomycin and piperacillin-tazobactam (VPT) administration, termed as the "workhorse" regimen at many institutions. In addition, she did not exhibit many clinical and laboratory signs of AIN, making diagnosis challenging. Prompt kidney biopsy and early steroid therapy had a critical role in recovery of the patient's renal function. The median duration for renal impairment in vancomycin-induced AIN is 26 days. Onset of AKI is usually rapid from VPT, within 3 - 5 days of drug exposure. However, the severity of AKI is often low, in contrast to this patient whose AKI reached a stage 3 (AKIN/KDIGO) within 2 days from drug exposure. This study highlights the nephrotoxic potential of piperacillin, especially when used along with vancomycin, concurrent with recent evidence. Within rising antibiotic usage rates, is important to consider AIN in the differential diagnosis of rapidly declining AKI, especially with the combined use of VPT.
RESUMO
BACKGROUND: To date, no data exist on gender-related publication biases in nephrology. This study was conducted to determine whether gender differences exist in the current literature published in high-ranking US nephrology journals, and how they may have changed over time. METHODS: The PubMed search was performed using the easyPubMed package in R, which extracted all articles indexed in PubMed from 2011 to 2021 from the US nephrology journals with the highest impact factors, i.e., Journal of the American Society of Nephrology (JASN), American Journal of Nephrology (AJN), American Journal of Kidney diseases (AJKD), and the Clinical Journal of the American Society of Nephrology (CJASN). Gender with predictions > 90% were accepted and the remaining were manually identified. Descriptive statistical analysis was carried out on the data. RESULTS: We identified 11,608 articles. On average, the ratio of male to female first authors decreased from 1.9 to 1.5 (p < 0.05). Additionally, in 2011, women accounted for 32% of first authors, a number that rose to 40% in 2021. All but the American Journal of Nephrology showed a variation in the ratio of men to women first authors. For the JASN, the ratio changed from 1.81 to 1.58, p = 0.001, for CJASN, the ratio declined from 1.91 to 1.15, p = 0.005 and for AJKD, the ratio declined from 2.19 to 1.19, p = 0.002. DISCUSSION AND CONCLUSIONS: Our study shows that gender biases in publications continue to exist in first-author publications in high-ranking Nephrology journals published in the US; the gap is however closing. We hope this study lays the groundwork to continue following and evaluating gender trends in publication.
