Quality of life transformations before and after kidney transplantation: A prospective qualitative study.

The aim of this IRB-approved study was to analyze prospectively quality of life (QOL) and psychological changes in 30 ESRD patients before and after kidney transplantation (KT). Semi-structured interviews were conducted after inclusion on the waiting list (A). Follow-up interviews were performed 6 months later with patients still awaiting KT (B6, n= 15), and with transplant recipients 6, 12 and 24 months after KT (C6, n=15; C12, n=15; C24, n=14). Qualitative thematic analysis was performed. A: All patients reported loss of freedom, 87% tried to maintain normality; 57% modified medical directives. All mentioned emotional fragility, negative thoughts (43%), and suicidal thoughts (20%) related to loss of QOL from dialysis (D), and professional tension (26%). B6: 40% reported no change compared to baseline, while 60% mentioned increase of illness intrusiveness, 46% D side effects, 40% communication problems, and 33% concerns about the waiting list handling. Fear of emotional breakdown (40%), couple problems (47%), and worsened professional difficulties (20%) were reported. C6: All patients reported recovery of QOL and concerns about acute rejection. 73% were anxious about laboratory results. 93% felt dependent on immunosuppressants (IS), 47% reported difficulties coping with their regimen, and 47% were concerned about side effects; 67% had resumed work, but medical constraints led 40% to professional stigmatization. C12: All enjoyed good QOL. Adherence to IS was mandatory (100%). All were aware of the limited long-term graft survival and 47% anxious about a possible return to D. 60% underlined positive life value; 47% resumed a full time job; 40% were on social security. C24: Good QOL was underlined (86%). Patients stated they would prefer re-TX to resuming D (71%). Post-TX health problems were mentioned (64%); increase of creatinine levels induced fear (36%). 79% complained about side effects. 64% reported changes in life values. This study reveals positive QOL and psychological transformations after KT, which are associated with positive changes related to graft survival and freedom from D. Psychological follow-up should be offered to patients who face relapsing ESRD or post-TX co-morbidities.

Feasibility and effectiveness of using coronary stents in the treatment of hepatic artery stenoses after orthotopic liver transplantation: preliminary report.

OBJECTIVE: Our aim is to evaluate the feasibility, efficacy, and patency of using coronary stents for the treatment of hepatic artery stenosis after liver transplantation. CONCLUSION: Hepatic artery stenosis after liver transplantation can be treated using coronary stents. The low rate of complication, high technical success, and 1-year patency rates are encouraging.

Varicella Zoster Virus CNS disease in hematopoietic cell transplantation: A single center experience

Background: Varciella Zoster Virus (VZV) can lead to serious complications in Hematopoietic Cell Transplant (HCT) recipients. Central nervous system (CNS) VZV can be one of the most devastating infections in transplant recipients, yet little is known about this rare disease. Objectives: To describe CNS VZV in the post-transplant period and to define potential risk factors in the HCT population. Methods: We reviewed the course of all patients who received a first HCT at the Fred Hutchinson Cancer Center (FHCRC) in Seattle, WA from 1/1996 through 12/2007. Data were collected retrospectively using the Long-Term Follow-Up database, which includes on-site examinations, outside records, laboratory tests, and yearly questionnaires. Patients were classified as CNS VZV if they had laboratory confirmation of VZV in the cerebrospinal fluid (CSF), or had zoster with associated clinical and laboratory findings consistent with CNS disease. Results: A total of six patients developed VZV CNS disease during the evaluation period (table 1). Diagnosis was confirmed in 3/6 by detection of VZV in CSF by PCR. All other patients had a clinical diagnosis based on the presence of CNS symptoms, zoster, lymphocytic pleiocytosis, and response to IV acyclovir. Patients who developed CNS disease had a mean age of 42 years (range 34-51) at time of transplant. CNS disease developed at a mean of 9 months posttransplantation (range 0.5-24 months), and severity varied, ranging from meningitis (3/6) to encephalitis/myelitis (3/6). All had active graft-versus host disease (GHVD) and all were being treated with immunosuppressive therapy at time of diagnosis. Fever and headache were the most common symptoms, but patients who developed focal CNS findings or seizures (3/6) had a more complicated clinical course. While most patients presented with classic VZV/zoster skin lesions, 2/6 patients had no dermatologic findings associated with their presentation. Four (66%) of patients who developed VZV CNS disease died, two related to VZV complications despite aggressive antiviral therapy. Conclusions: In this cohort of HCT patients, VZV CNS disease was a rare complication. Mortality due to CNS VZV is high, particularly in patients who develop focal neurologic findings or seizures. Even in the absence of skin lesions, VZV CNS disease should be considered in patients who develop fevers and neurologic symptoms.

Influence of IFNL3/4 Polymorphisms on the Incidence of Cytomegalovirus Infection After Solid-Organ Transplantation.

BACKGROUND: Polymorphisms in IFNL3 and IFNL4, the genes encoding interferon λ3 and interferon λ4, respectively, have been associated with reduced hepatitis C virus clearance. We explored the role of such polymorphisms on the incidence of cytomegalovirus (CMV) infection in solid-organ transplant recipients. METHODS: White patients participating in the Swiss Transplant Cohort Study in 2008-2011 were included. A novel functional TT/-G polymorphism (rs368234815) in the CpG region upstream of IFNL3 was investigated. RESULTS: A total of 840 solid-organ transplant recipients at risk for CMV infection were included, among whom 373 (44%) received antiviral prophylaxis. The 12-month cumulative incidence of CMV replication and disease were 0.44 and 0.08 cases, respectively. Patient homozygous for the minor rs368234815 allele (-G/-G) tended to have a higher cumulative incidence of CMV replication (subdistribution hazard ratio [SHR], 1.30 [95% confidence interval {CI}, .97-1.74]; P = .07), compared with other patients (TT/TT or TT/-G). The association was significant among patients followed by a preemptive approach (SHR, 1.46 [95% CI, 1.01-2.12]; P = .047), especially in patients receiving an organ from a seropositive donor (SHR, 1.92 [95% CI, 1.30-2.85]; P = .001), but not among those who received antiviral prophylaxis (SHR, 1.13 [95% CI, .70-1.83]; P = .6). These associations remained significant in multivariate competing risk regression models. CONCLUSIONS: Polymorphisms in the IFNL3/4 region influence susceptibility to CMV replication in solid-organ transplant recipients, particularly in patients not receiving antiviral prophylaxis.

Sélection et suivi prétransplantation des patients candidats à la greffe cardiaque en Suisse romande [Selection and preoperative follow-up of heart transplantation candidates in the French part of Switzerland].

Heart transplantation (HTx) started in 1987 at two university hospitals (CHUV, HUG) in the western part of Switzerland, with 223 HTx performed at the CHUV until December 2010. Between 1987 and 2003, 106 HTx were realized at the HUG resulting in a total of 329 HTx in the western part of Switzerland. After the relocation of organ transplantation activity in the western part of Switzerland in 2003, the surgical part and the early postoperative care of HTx remained limited to the CHUV. However, every other HTx activity are pursued at the two university hospitals (CHUV, HUG). This article summarizes the actual protocols for selection and pre-transplant follow-up of HTx candidates in the western part of Switzerland, permitting a uniform structure of pretransplant follow-up in the western part of Switzerland.

Toward improved immunocompetence of adoptively transferred CD8+ T cells.

Adoptive transfer of autologous or allogenic T cells to patients is being used with increased frequency as a therapy for infectious diseases and cancer. However, many questions remain with regard to defining optimized procedures for preparation and selection of T cell populations for transfer. In a new study in this issue of the JCI, Gattinoni and colleagues used a TCR transgenic mouse model to examine in vitro-generated tumor antigen-specific CD8+ T cells at various stages of differentiation for their efficacy in adoptive immunotherapy against transplantable melanoma. The results confirm that CD8+ T cells progressively lose immunocompetence with prolonged in vitro cultivation and suggest that effector CD8+ T cells alone may be considerably less potent at protecting hosts with advanced tumors than are less differentiated T cells.

Effects of immunosuppressive drugs on HIV infection: implications for solid-organ transplantation.

With the advent of highly active antiretroviral therapy (HAART), HIV infection has become a chronic disease. Various end-stage organ failures have now become common co-morbidities and are primary causes of mortality in HIV-infected patients. Solid-organ transplantation therefore has been proposed to these patients, as HIV infection is not anymore considered an absolute contraindication. The initial results of organ transplantation in HIV-infected patients are encouraging with no differences in patient and graft survival compared with non-HIV-infected patients. The use of immunosuppressive drug therapy in HIV-infected patients has so far not shown major detrimental effects, and some drugs in combination with HAART have even demonstrated possible beneficial effects for specific HIV settings. Nevertheless, organ transplantation in HIV-infected patients remains a complex intervention, and more studies will be required to clarify open questions such as long-term effects of drug interactions between antiretroviral and immunosuppressive drugs, outcome of recurrent HCV infection in HIV-infected patients, incidence of graft rejection, or long-term graft and patient survival. In this article, we first review the immunological pathogenesis of HIV infection and the rationale for using immunosuppression combined with HAART. We then discuss the most recent results of solid-organ transplantation in HIV-infected patients.

Recurrent Hepatitis C After Liver Transplantation Experience of the First 21 Patients Treated in Lausanne

BACKGROUND AND AIM: Recurrent hepatitis C is a major cause of morbidity and mortality after liver transplantation (LT), and optimal treatment algorithms have yet to be defined. Here, we present our experience of the first 21 patients with recurrent hepatitis C treated in Lausanne. PATIENTS AND METHODS: Twenty-one patients with histologyproven recurrent hepatitis C after LT were treated since 2003. Treatment was initiated with pegylated interferon-α2a 135 μg per week and ribavirin 400 mg per day in the majority of patients, and subsequent doses were adapted individually based on on-treatment virological responses and clinical and/or biochemical side effects. RESULTS: On an intention-to-treat basis, sustained virological response (SVR) was achieved in 12/21 (57%) patients (5/11 [45%], 2/3 [67%], 4/5 [80%] and 1/2 [50%] of patients infected with genotypes 1, 2, 3 and 4, respectively). Two patients experienced relapse and 6 did not respond to treatment (NR). Treatment duration ranged from 24 to 90 weeks. It was stopped prematurely due to adverse events in 5/21 (24%) patients (with SVR achieved in 2 patients, NR in 2 patients, and death of one patient awaiting re-transplantation). Of note, SVR was achieved in a patient with combined liver and kidney transplantation. Importantly, SVR was achieved in some patients despite the lack of an early virological response or HCV RNA negativity at week 24. Darbepoetin α and filgrastim were used in 33% and 14%, respectively. CONCLUSION: Individually adapted treatment of recurrent hepatitis C can achieve SVR in a substantial proportion of LT patients. Conventional stopping rules do not apply in this setting so that prolonged therapy may be useful in selected patients.

The use of the Family Management Style Framework to evaluate the family management of liver transplantation in adolescence

Objective: To understand the family management experience of liver transplantation during adolescence based on the Family Management Style Framework(FMSF). Method: This is a case study that used the FMSF as theoretical framework and the hybrid model of thematic analysis as methodological reference. The case presented is from an adolescent’s family that lives in Salvador, Bahia. The data were collected through interviews with the mother and the patient charts analysis. Results: The results shows that the family defines the transplantation as threatening and there are divergence between mother and daughter related to the teen’s capabilities perception. Facing those discrepancies, the family assumes a protective posture by believing that the teen cannot take care of herself alone. The perceived consequences reflect how much the uncertainty permeates the family environment. Conclusion: It is concluded that the use of a model to evaluate the management can help professionals to direct and plan specific interventions.



Multi-layer amniotic membrane (MLAM) transplantation for non traumatic corneal perforations or descemetoceles

Purpose:To describe the indications, the surgical procedure and the clinical outcome of MLAM in the treatment of non traumatic corneal perforations and descemetoceles . Methods:A prospective, non comparative, interventional case series of eight consecutive patients (mean age 59 years old, 6 men and 2 women) with non traumatic corneal perforations or descemetoceles.The surgery consisted in a MLAM transplantation of a cryopreservated human amniotic membrane. The series included: three active herpetic keratitis, one rosacea, one perforation of an hydrops, one cicatricial pemphigoid, one perforation after an abcess in a corneal graft and one perforation after protonbeamtherapy. The clinical outcome included: the follow-up, the integrity of the eye, corneal epithelialization, inflammation and neovascularization, and the integration of the MLAM. Stromal thickness was followed precisely with the slit lamp. A corneal graft was performed at one patient after the MLAM, allowing microscopic investigation of the removed MLAM integrated in the cornea. Results:The mean follow-up was 8.78 months (range 3.57 to 30.17). Amniotic membrane transplantation was successful and reduced inflammation in 7 patients out of 8 ,after one procedure.One patient who presented a large herpetic keratitis epithelial defect with corneal anaesthesia had his MLAM dissolved after two weeks with an aqueous leakage. Epithelium healed within 3 weeks above 7 MLAM and remained stable at 3 months in 7 out of 8 patients. MLAM opacification gradually disappeared over a few months, however, stromal layers filling in the corneal perforations or above the descemetoceles remained stable. Conclusions:MLAM transplantation is a safe, effective and useful technique to cure non traumatic corneal perforations and descemetoceles. It can be performed in emergency despite the presence of an active inflammation or infection. By facilitating epithelialization, reducing inflammation and neovascularization, it allows corneal surface reconstruction in patients with persistent epithelial defects and corneal melting that usually ends in a perforation. For full visual rehabilitation, a delayed penetrating keratoplasty is required.

Psychological transformations in kidney transplantation: A prospective qualitative study

The aim of this IRB-approved study was to prospectively analyze psychological transformations in ESRD patients before and after transplantation (KT). Semi-structured interviews were conducted in 30 patients (mean age = 53±10) after their inclusion on the waiting-list (Gr. A). Follow-up interviews were performed 6 months later in 15 patients still awaiting KT (Gr. B6), and in 15 patients 6 months (Gr. C6) and 12 months (Gr. C12) after KT. Qualitative analysis was performed. Gr: A:All patients underlined loss of freedom, 87% devoted much energy to maintain normality, 57% modified medical directives. All reported emotional fragility related to dialysis and loss of quality of life (QOL), negative (43%) or suicidal thoughts (20%). Professional stigma was underlined (26%). Gr: B6:40% reported no change, 60% mentioned increase of illness intrusiveness, 46% dialysis side-effects, 40% communication problems, 33% tension with medical staff and waiting list handling. Fear of emotional breakdown (40%), couple problems (47%) and worsened professional difficulties (20%) were reported. Gr: C6:All patients mentioned improved QOL and freedom recovery (87%). All expressed concerns about possible acute rejection, 73% were anxious about laboratory results, 93% experienced dependence to immunosuppressants, 47% reported difficulties in handling medication, 21% feared to forget them, 47% were concerned about side-effects, 67% had resumed work but medical constraints led to professional tension (40%). Gr: C12:All mentioned recovered QOL. Medical controls were accepted as a routine (87%) and adherence to medication was mandatory (100%). All mentioned the limited long-term graft survival and 47% were anxious about possible return to dialysis, especially younger patients (27%). Positive identity and existential changes were reported (60%). This prospective qualitative study identifies psychological modifications in the course of KT. It provides a basis to adequately address concerns, but it shows also that KT is clearly associated with positive psychological transformations.
