Patients were divided into two groups as those with elastography scores higher than 8.45 kPa (n = 50) and those with elastography scores equal to or lower than 8.45 kPa (n = 50). Elastography measurements were performed with Siemens Acuson S2000 ultrasound system and the scores were compared with renal function parameters and other clinical characteristics.Results: Patients with high elastography scores had smaller kidney size (P = .010), lower eGFR (P = .002), and higher proteinuria and albuminuria levels (P < .05) than patients with low elastography scores. There was a significant association between elastography score and the risk of renal dysfunction (OR = 1.039, P = .006).Conclusions: A large elastography score may act as a significant biomarker for prognosing the risk of renal dysfunction in subjects undergoing kidney transplantation. These findings suggest that elastography may become an invaluable noninvasive tool during the long-term follow-up of patients with renal transplants.","PeriodicalId":94258,"journal":{"name":"Transplantation proceedings","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143639957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although parathyroidectomy (PTx) is an effective treatment option for post-KTx HPT, it is associated with postoperative elevation of serum creatinine levels. We hypothesized that pre-PTx calcimimetic treatment could alleviate the post-PTx increase in serum creatinine levels.Methods: This retrospective cohort study enrolled KTx patients who underwent initial PTx between 2004 and 2023. Patients' background characteristics and laboratory data were investigated. The primary outcome was a change in the estimated glomerular filtration rate (eGFR). The cohort was divided into 2 groups based on the presence of pre-PTx calcimimetic treatment. Multivariate linear regression analysis assessed the association between calcimimetic treatment and percent eGFR 1 week after PTx.Results: Of the 77 KTx patients who underwent PTx, 28 were treated with pre-PTx calcimimetics (calcimimetic group), and the others were not (noncalcimimetic group). Compared with the noncalcimimetic group, the calcimimetic group had lower serum calcium levels before PTx (10.3 vs 11.2 mg/dL, P < .001) and a significantly higher percentage of eGFR 1 week after PTx (95.1% vs 81.5%, P < .001). According to the multivariate analysis, pre-PTx calcimimetic treatment was positively associated with percent eGFR (regression coefficient estimate, 13.76; 95% confidence interval, 7.02-20.50; P < .001) 1 week after PTx.Conclusion: Pre-PTx calcimimetic treatment may prevent post-PTx elevation of serum creatinine levels in KTx patients.","PeriodicalId":94258,"journal":{"name":"Transplantation proceedings","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143639958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Serologic studies have great importance for understanding the virus's behavior in populations, as it can suggest the status of the epidemic in a community. This cross-sectional study aimed to analyze the serologic profile for COVID-19 in patients before and after pediatric heart transplantation.Methods: Serology data on IgG and IgM antibodies for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were collected in patients of the Pediatric Cardiology and Congenital Heart Diseases unit of a Brazilian hospital between January and August 2022. A total of 174 patients were recruited, including 28 on the transplantation waiting list and 146 heart transplant recipients. Information for each patient, including demographics (age, sex, state of origin), type of heart disease (congenital or acquired), and time after transplantation, was analyzed.Results: Overall, 72 patients had a positive serology for anti-N antibodies (48.0%), including 62 heart transplant recipients and 10 patients on the transplantation waiting list, The positivity rates in these 2 groups were 48.1% and 47.6%, respectively. Positivity rates for previously infected individuals were 62.5% and 62.1%, respectively.Conclusions: Approximately one-half of our study sample had IgM or IgG antibodies against the SARS-CoV-2 virus. Serologic studies on the duration and level of protection provided by these antibodies are relevant public health tools for health promotion of vulnerable groups and can be useful for future studies on antibody behavior.","PeriodicalId":94258,"journal":{"name":"Transplantation proceedings","volume":" ","pages":"1112-1114"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140961354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Serum creatinine (sCr) after 3 months of diagnosis of COVID-19 varied according to the severity of infection. The lethality rate was higher in the group with severe symptoms (65%) compared with those with mild infection (1.5%).Conclusion: The increase in sCr was associated with disease severity.
