Breaking through the steroid stigma: a single-centre study on topical corticosteroid perception and adherence in dermatology patients and caregivers.

INTRODUCTION: Topical corticosteroid phobia is a common phenomenon that can result in poor treatment adherence and therapeutic failure. OBJECTIVES: This study aims to evaluate the prevalence and degree of topical corticosteroid phobia and its impact on treatment adherence in various dermatological conditions. Additionally, we explored the sources of information regarding topical corticosteroids. MATERIALS AND METHODS: A cross-sectional study was conducted among 300 participants with topical corticosteroid usage experience. Topical corticosteroid phobia was assessed with the topical corticosteroid phobia (TOPICOP) scale, and treatment adherence was measured with the Elaboration d'un outil d'evaluation de l'observance des traitements medicamenteux (ECOB) score. Information sources regarding topical corticosteroids were identified, and their level of trust was assessed. The data were collected via questionnaires in three languages, namely English, Malay and Mandarin. RESULTS: The study found that topical corticosteroid phobia was prevalent, with 98% of participants expressing a certain degree of phobia. The mean global TOPICOP score was 32.7 ± 6.7%. The mean score of each domain was 27.1 ± 17.2% for knowledge and belief, 35.7 ± 23.8% for fears and 40.8 ± 25.8% for behaviour. Patients/caregivers who have eczema, highly educated, severe disease, low tolerability to symptoms, previous adverse effects with topical corticosteroids and tend to traditional/non-steroidal alternative therapy usage had a significant association with topical corticosteroid phobia (p<0.05). Dermatologists were the most common and trusted source of information on topical corticosteroids. CONCLUSIONS: This study highlights the widespread topical corticosteroid phobia in dermatological practice. Dermatologists should take the lead in combating steroid phobia and provide patients with public awareness regarding topical corticosteroids to improve treatment adherence and therapeutic outcomes.

Emotional well-being of living kidney donors: findings from the RELIVE Study.

Following kidney donation, short-term quality of life outcomes compare favorably to US normative data but long-term effects on mood are not known. In the Renal and Lung Living Donors Evaluation Study (RELIVE), records from donations performed 1963-2005 were reviewed for depression and antidepressant use predonation. Postdonation, in a cross-sectional cohort design 2010-2012, donors completed the Patient Health Questionnaire (PHQ-9) depression screening instrument, the Life Orientation Test-Revised, 36-Item Short Form Health Survey and donation experience questions. Of 6909 eligible donors, 3470 were contacted and 2455 participated (71%). The percent with depressive symptoms (8%; PHQ-9>10) was similar to National Health and Nutrition Examination Survey participants (7%, p=0.30). Predonation psychiatric disorders were more common in unrelated than related donors (p=0.05). Postdonation predictors of depressive symptoms included nonwhite race OR=2.00, p=0.020), younger age at donation (OR=1.33 per 10 years, p=0.002), longer recovery time from donation (OR=1.74, p=0.0009), greater financial burden (OR=1.32, p=0.013) and feeling morally obligated to donate (OR=1.23, p=0.003). While cross-sectional prevalence of depression is comparable to population normative data, some factors identifiable around time of donation, including longer recovery, financial stressors, younger age and moral obligation to donate may identify donors more likely to develop future depression, providing an opportunity for intervention.

Demographic, metabolic, and blood pressure characteristics of living kidney donors spanning five decades.

While cautious criteria for selection of living kidney donors are credited for favorable outcomes, recent practice changes may include acceptance of less than ideal donors. To characterize trends in donor acceptance, the Renal and Lung Living Donors Evaluation (RELIVE) Study evaluated 8,951 kidney donors who donated between 1963 and 2007 at three major U.S. transplant centers. Over the study interval, there was an increase in the percentage of donors >40 years old from 38% to 51%; donors >60 years varied between 1% and 4%. The proportion of donors with obesity increased from 8% to 26% and with glucose intolerance from 9% to 25%. The percentage of hypertensive donors was consistent (5-8%). Accepted donors ≥60 years old were more likely to have obesity, glucose intolerance, and/or hypertension compared to younger donors (p<0.0001). Our results demonstrate important trends in acceptance of older and more obese donors. The fraction of older donors accepted with glucose intolerance or hypertension remains small and for the majority includes mild elevations in glucose or blood pressure that were previously classified as within normal limits.

Isolated central nervous system posttransplant lymphoproliferative disorder treated with high-dose intravenous methotrexate.

Posttransplant lymphoproliferative disorder (PTLD) is an uncommon neoplastic complication of kidney transplantation, affecting about 1% of recipients. It is generally associated with Epstein-Barr virus (EBV) infection of B-lineage lymphocytes. Central nervous system (CNS) involvement is rare. There is little clinical experience with treatment of CNS PTLD due to the relative rarity of the disease other than reduction or withdrawal of immunosuppression, but it is usually fatal. We describe six patients with renal allografts and histologically proven isolated CNS PTLD. Tissue analysis from the biopsy specimens was positive for EBV material in five of the six patients. All six patients were treated with high-dose intravenous methotrexate (HD IV MTX). Methotrexate was initiated at 8 g/m2, with later adjustments for creatinine clearance. With MTX therapy, four patients have had a sustained complete response, and two had progressive disease and were referred for radiation therapy. This finding suggests a subgroup of patients may benefit from MTX but our case series is inadequate to describe overall efficacy. No unexpected toxicities were encountered in 37 courses of treatment. HD IV MTX chemotherapy should be considered as an alternative for treatment of CNS PTLD.

Postransplant lymphoproliferative disorder localized near the allograft in renal transplantation.

BACKGROUND: Posttransplant lymphoproliferative disorder (PTLD), a complication of immunosuppression, develops in approximately 1% of renal allograft recipients. Typically, PTLD is a proliferation of B-cells associated with Epstein-Barr virus (EBV) infection; it is said to be most often a systemic disease. Involvement occasionally is localized near the allograft. METHODS: This is a retrospective analysis of all cases of PTLD in recipients of 1474 renal transplants performed at University of Alabama at Birmingham between 1993 and 1997. RESULTS: Of 14 patients developing PTLD, 10 had disease localized near the allograft. The mean interval from transplantation to diagnosis was 221 +/- 70 days. All patients presented with renal dysfunction; an ultrasound examination revealed a hilar mass, with hydronephrosis in five and stenosis of renal vessels in eight. No patient had lymphadenopathy, according to computerized tomographic or magnetic resonance imaging findings. After reduction of immunosuppressive therapy, seven required a nephrectomy because of rejection, progressive dysfunction, or mass enlargement. Tissue recovered in four patients was consistent with PTLD; the tumors in the remaining three patients were unresectable and regressed. One patient died 1 month after a nephrectomy, and another died 4 years after surgery; neither had evidence of PTLD when they died. Three patients retain functional grafts without clinical or radiographical evidence of progression. All patients with disseminated disease died. CONCLUSIONS: In a large cohort of renal allograft recipients, PTLD affected 1%. Disease localized near the allograft was the most common variant. For most patients with localized disease, the outcome was graft loss, and the mortality was low. Localized PTLD should be considered in the differential diagnosis of allograft dysfunction in the 1st posttransplant year.

High flux plasma exchange using a modified rotating membrane system.

The results of increasing blood flow capability in a modified system for plasma exchange with a rotating filter are reported. There were 742 treatments performed with the authors' original system (OS), limited to blood flows of 100 ml/ min, and 327 treatments performed with the updated system (US), allowing for blood flows of 150 ml/min. Blood flows for OS were 98 +/- 5 ml/min (mean +/- SD) vs 145 +/- 12 ml/min for US (p < 0.001). Plasma flows were 65 +/- 7 ml/min for OS vs 98 +/- 12 ml/min for US (p < 0.001). Plasma removal rate was 42 +/- 8 ml/min for OS vs 61 +/- 14 ml/min for US (p < 0.001). Mean treatment time was reduced from 76 +/- 23 min for OS to 52 +/- 17 min for US (p < 0.001) in spite of providing a similar amount of plasma removed per treatment (3,113 +/- 577 ml/Rx for OS vs 3078 +/- 797 ml/Rx for US; p = 0.48). Despite statistical significance, there were only small differences in filtration fractions (65 +/- 12% for OS vs 62 +/- 11% for US; p < 0.001) and patient hematocrits (34 +/- 6% for OS vs 33 +/- 6% for US; p < 0.001). In conclusion, modification of the OS to allow for increased blood flow has resulted in a substantial improvement in procedure efficiency and a clinically useful decrease in treatment time.

Metastatic testicular carcinoma from the colon with clinical, immunophenotypical, and molecular characterization: report of a case.

We report a case of testicular metastasis from a colonic adenocarcinoma. The presentation of testicular metastasis, diagnosis, management, and possible modes of spread are reported. In addition to conventional investigations and histopathologic techniques, a molecular study of the testicular metastasis and colon primary, using microsatellite analysis, was performed to confirm the primary origin. Its potential uses are discussed.

The best way to manage hypertension after renal transplantation.

Hypertension in renal allograft recipients is a common problem arising from multiple factors, including peripheral vascular damage caused by pretransplant hypertension, side effects of immunosuppressive medications, allograft dysfunction, renal artery stenosis, recurrent glomerulonephritis, synthesis of vasoconstrictive hormones by the native kidneys, and excessive dietary salt intake. Identification of modifiable factors causing hypertension and concurrent medical conditions, and measurement of glomerular filtration rate, cyclosporine/tacrolimus blood levels, and magnitude of proteinuria are essential to tailor treatment for an individual patient. Lifestyles that exacerbate hypertension should be modified. For pharmacological therapy, diuretics and calcium channel blockers are first-line agents in patients on cyclosporine shortly after transplant. Angiotensin-converting enzyme inhibitors are good choices for patients with significant proteinuria. Reduction of immunosuppression will improve hypertension in some patients, but entails a potential risk of rejection or graft loss. Angioplasty is necessary in patients with a functionally significant stenosis of the allograft renal artery. Other patients on maximal medical therapy may benefit from native nephrectomy.

Focal posttransplantation lymphoproliferative disorder at the renal allograft hilum.

OBJECTIVE: This report describes the imaging characteristics of focal posttransplantation lymphoproliferative disorder. CONCLUSION: Posttransplantation lymphoproliferative disorder may be limited to the allograft. A focal complex mass in the renal allograft hilum surrounding the main renal blood vessels is a common finding and can be visualized with sonography. MR imaging can help increase diagnostic confidence.
