Unexpectedly High Efficacy of SARS-CoV-2 BNT162b2 Vaccine in Liver versus Kidney Transplant Recipients-Is It Related to Immunosuppression Only?

The BNT162b2 vaccine is reportedly effective in preventing severe disease in more than 90% of the general population, but its efficacy in transplant recipients remains controversial. We aimed to determine the immune response to the BNT162b2 vaccine in kidney (KTRs) and liver transplant recipients (LTRs). In this retrospective cohort study, we included randomly 65 KTRs and 65 LTRs, who received two 30 μg doses of BNT162b2 vaccine in 3-to6-week intervals.

Reversal of stage 5 chronic kidney disease by aortic valve replacement in kidney transplant recipient: a case report.

Background: Cardiorenal syndrome (CRS) is a group of pathophysiological disorders affecting heart and kidneys.

Case Presentation: We present 44-year-old kidney transplant recipient with acute-on-chronic graft failure in the course of CRS due to acutely decompensated heart failure associated with severe aortic regurgitation successfully treated with aortic valve replacement. Because of graft failure progression and difficult to eradicate infections he was treated with dialysis and radical minimization of immunosuppression.

Plasma microRNA-126-3p and neutrophil-to-lymphocyte ratio in patients with chronic kidney disease: relationships to ambulatory 24-h blood pressure.

Pro-inflammatory milieu of chronic kidney disease (CKD) results in endothelial damage and contributes to increased cardiovascular risk. The aim of the study was to evaluate association between neutrophil-to-lymphocyte ratio (NLR) and plasma relative expression of endothelially abundant miR-126-3p with circadian blood pressure (BP) pattern in CKD patients. This single-center observational study involved CKD stage 1-5 patients and healthy age- and sex-matched control subjects.

CXCL12 in Patients with Chronic Kidney Disease and Healthy Controls: Relationships to Ambulatory 24-Hour Blood Pressure and Echocardiographic Measures.

Background/aims: Chronic kidney disease is a pro-inflammatory condition where the interplay between different regulatory pathways and immune cells mediates an unfavorable remodeling of the vascular wall and myocardial hypertrophy. These mechanisms include the action of CXCL12. The aim of this study is to evaluate the association between serum CXCL12 with left ventricular hypertrophy (LVH) and blood pressure control in chronic kidney disease (CKD) patients.

Circadian and short-term blood pressure abnormalities after liver transplantation.

Liver transplantation remains the only therapeutic method in end-stage liver disease. Cardiovascular system diseases, including arterial hypertension, are considered one of the main risk factors increasing mortality in this population. The aim of the study was the evaluation of circadian blood pressure patterns in liver transplant recipients.

Plasma microRNA-155-5p is increased among patients with chronic kidney disease and nocturnal hypertension.

MicroRNAs play multiple roles in the regulation of blood pressure (BP). Nevertheless, to date, no study has assessed the association between microRNA plasma expression and BP control in chronic kidney disease (CKD) patients. Given this background, we evaluated the plasma expression of miR-155-5p, a translational inhibitor of angiotensin receptor type I, in CKD patients, to determine the association between miR-155-5p level and BP control.

Simple platelet markers: Mean platelet volume and congestive heart failure coexistent with periodontal disease. Pilot studies.

Background: Conducted pilot study concerning mean platelet volume (MPV) parameter among patients suffering from congestive heart failure and periodontal disease.

Methods: Examination of dynamic changes of platelet and periodontal markers in group of 50 patients before and an average of 6 months subsequent to professional periodontal treatment.

Results: Both platelet and periodontal parameters decreased after periodontal treatment, what is more, the decrease of MPV value due to periodontal disease/mm improvement was shown to be statistically significant (p = 0.

Plasmatic NT-proBNP concentrations in patients with coexistent periodontal disease and congestive heart failure: pilot studies.

Background: The presented pilot study was conducted in order to evaluate dynamic fluctuations of blood inflammation markers among patients with congestive heart failure (CHF) and coexistent periodontitis (PD).

Aim: The study hypothesis stated that elimination of chronic inflammation caused by PD has a significant impact on inflammation markers and, secondarily, also on the course and prognosis of CHF. N-terminal pro-B-type natriuretic peptide (NT-proBNP) and tumour necrosis factor alpha (TNF-α) markers were assessed due to their proven diagnostic significance.

Blood pressure and intracranial aneurysms in autosomal dominant polycystic kidney disease.

Background/aims: Autosomal dominant polycystic kidney disease (ADPKD) is correlated with an increased frequency of both intracranial aneurysms (ICANs), and arterial hypertension (AH). The aim of our study was to search for the association between blood pressure (BP) and ICANs in ADPKD patients.

Methods: Sixty-eight adult, pre-dialysis phase ADPKD patients underwent both screening for ICANs with magnetic resonance angiography of the brain, and ambulatory blood pressure monitoring (ABPM).

Rehabilitation and 6-minute walk test after liver transplantation.

Background: Measurement of exercise capacity is an integral element to assess patients after surgery. Although the 6-minute walk test (6MWT) provides information regarding functional capacity, response to therapy, and prognosis across a range of conditions, its applicability for liver transplant recipients remains to be established. The aim of our study was to examine whether the 6MWT in combination with a subjective rating of perceived exertion (Borg Scale [BS]) could be used to evaluate exercise capacity among patients after liver transplantation (OLT).

Prevention of hepatitis B recurrence after liver transplantation using lamivudine and hepatitis B immune globulin.

Background: Patients undergoing liver transplantation (ltx) for hepatitis B-related liver disease are prone to recurrence. Historically, ltx has been associated with aggressive reinfection and poor survival results. The mainstay of prophylaxis has been passive immunotherapy with hepatitis B immune globulin(HBIG).

Recurrence of primary sclerosing cholangitis in patients after liver transplantation.

Background: Primary sclerosing cholangitis (PSC) is a chronic cholestatic disease that progresses to end-stage liver disease. There are several specific problems related to the posttransplantation period in these patients. The aim of this study was to analyze a single center experience with 17 orthotopic liver transplantations (OLT) due to PSC.

Economic evaluation of sirolimus-based immunosuppressive regimens in kidney graft recipients.

Introduction: The aim of this study was an economic evaluation of three sirolimus (SRL)-based regimens in the first 2 years after renal transplantation.

Materials And Methods: The three SRL-based immunosuppressive regimens in renal transplant patients between June 2000 and September 2002 were: (1) SRL + steroids + cyclosporine (CsA) permanently; (2) SRL + steroids + tacrolimus (Tac); and (3) SRL + steroids + CsA, with CsA discontinuation at 3 months posttransplant. Ten patients were included in each group in an intent-to-treat analysis.

Renal function after liver transplantation: calcineurin inhibitor nephrotoxicity.

Renal failure, mainly due to calcineurin inhibitor (CNI) nephrotoxicity, is the most common complication following orthotopic liver transplantation (ltx). The aim of this study was to evaluate the incidence and course of renal failure in adult ltx patients. Severe acute renal failure in early postoperative period due to impaired hemodynamics and CNI nephrotoxicity, occurred in 14 patients, 3 of whom required dialysis.

[Effect of immunosuppressive treatment on diurnal profile of blood pressure].

Prevalence of arterial hypertension suddenly rose in patients after renal transplantation since cyclosporine A was introduced. Arterial hypertension is now diagnosed in 67-90% of patients after renal transplantation. It has not only negative effect on cardiovascular system but also shortens survival of renal graft.

[Expression of mRNA for growth factors and cytokines in the renal artery wall of chronically rejected renal allograft].

The vascular hallmark of chronic rejection (CR), as well as of atherosclerosis, is initial hyperplasia. It results from migration and proliferation of vascular smooth muscle cell and increased deposition of extracellular matrix proteins. A possible mechanism responsible for formation of neointima is the release of growth factors and cytokines, such as: transforming growth factor beta (TGF-beta), tumour necrosis factor alfa (TNF-alpha), interleukin 1 (IL-1) and interleukin 6 (IL-6).

[Noninvasive monitoring of chronic glomerulonephritides progression].

Progression to end-stage renal failure is the final common pathway of many forms of glomerular diseases, independent of the type of initial insult. Tubulointerstitial fibrosis is tis near invariable finding and significant prognostic feature. We have reviewed immunological (cytokines, inflammatory cells) and nonimmunological factors (extracellular matrix proteins and proteolytic enzymes), being involved in mechanisms leading from glomerular disease to tubulointerstitial scarring, from the point of view of potential clinical usefulness of measuring its urine activities and levels to noninvasive diagnostic of kidney diseases.

[Treatment of diabetes mellitus in patients after renal transplantation].

Diabetes mellitus (DM) is the most common metabolic disease, an independent risk factor of coronary disease, and shortens lifetime in all populations of patients, including kidney transplant recipients. Patients after kidney transplantation are exceptionally predisposed to develop or to exacerbate the preexisting DM. Age, DM in family, CMV infections, genetic factor (HLA A26 and B27), immunosuppressive treatment with steroids or calcineurin inhibitors belong to the major risk factors of diabetes.
