The aim of this study was to compare liver transplant recipients (LTRs) with the general population regarding their knowledge of skin cancer, sun health, sun protection behaviors, and affecting factors. This cross-sectional study was conducted in Turkey between March 2016 and September 2016 with 104 LTRs and 100 participants from the general population group (GPG). The mean age of the LTRs was 53.2 ± 11.8 and that of the GPG was 42.7 ± 14.5. The LTRs' skin cancer and sun knowledge were significantly lower than in the GPG, but there was no difference between the two groups in terms of their sun protection behavior scores...

Radiation is an important therapy for cancer with many benefits; however, its side effects, such as impaired wound healing, are a major problem. While many attempts have been made to overcome this particular disadvantage, there are few effective treatments for impaired wound healing in an X-ray-irradiated field. One reason for this deficiency is the lack of experimental models, especially animal models. We have previously reported a mouse model of impaired wound healing in which the irradiation area was restricted to the hindlimbs...

Bordetella bronchiseptica is a gram-negative coccobacillus that infects animals, but rarely affects humans. B. bronchiseptica has been reported to cause disease in immunocompromised hosts. We present a case of a 61-year-old man with a renal transplant who developed B. bronchiseptica bacteremia likely as a result of close contact between dogs and his skin cancer biopsy sites. The patient was successfully treated with 2 weeks of oral levofloxacin. This case alerts physicians to B. bronchiseptica as a cause of bacteremia in solid organ transplant patients with exposure to animals...

Fibroblast growth factor-binding protein 1 (FGFBP1, FGF-BP) is a secreted chaperone that mobilizes paracrine-acting FGFs, stored in the extracellular matrix, and presents them to their cognate receptors. FGFBP1 enhances FGF signaling including angiogenesis during cancer progression, and is upregulated in various cancers. Here we evaluated the contribution of endogenous FGFBP1 to development and homeostasis as well as to skin pathologies utilizing Fgfbp1-knockout (KO) mice. Relative to wild-type (WT) littermates KO mice showed no gross pathologies...

Actinic keratoses (AKs) are highly dynamic lesions and AK activity has been shown to be associated with squamous cell carcinoma (SCC). We sought to explore risk factors which may affect the 12-month turnover of AKs in organ transplant recipients (OTRs). The number of incident AKs, regressed AKs and net change in AK counts were calculated. Negative binomial regression and Poisson regression models were used to estimate rate ratios (RR) for these 3 outcomes. Among 150 renal and 89 liver OTRs, those who spent > 50% of a typical weekday in the sun had a lower rate of AK regression than those who spent minimal time in the sun during a typical weekday...

Most cancer forms known to be caused by viruses are increased among the immunosuppressed, but several cancer forms without established viral etiology are also increased, notably non-melanoma skin carcinoma (NMSC). We followed all 13429 solid organ transplantation patients in Sweden for cancer occurrence after transplantation. We requested these tumor specimens and sequenced the first 89 specimens received (62 NMSCs, 27 other cancers). The sequences were analyzed for viruses based on two bioinformatics algorithms (paracel-blast (sensitive for detection of known viruses) and hidden Markov model (HMM; sensitive for distantly related viruses))...

BACKGROUND: Heart transplantation (HTx) is the preferred treatment for patients with end-stage heart failure and has been successful for >30 y. The clinical course of recipients at the extreme of age is unknown. We reviewed our experience to determine the overall health and prevalence of Tx-related medical problems for recipients in their ninth decade. METHODS: We reviewed the UCTP experience from 1985 to present to identify patients who survived into their 80s and matched (1:1) with other recipients for gender and age at HTx, but did not survive to ≥80 y...

OBJECTIVES: Recent studies have shown a high prevalence of hypovitaminosis D, defined as a serum 25-hydroxyvitamin D level less than 30 ng/ml, in both healthy populations and patients with chronic kidney disease. Patients undergoing kidney transplant are at an increased risk of skin cancer and are advised to avoid sunlight exposure. Therefore, these patients might share two major risk factors for hypovitaminosis D: chronic kidney disease and low sunlight exposure. This paper describes the prevalence and clinical characteristics of hypovitaminosis D among patients undergoing kidney transplant...

There is emerging evidence on the mechanisms of pancreatic cancer pain. Following the establishment of an orthotropic transplantation model of pancreatic cancer, microarray analysis was performed to identify changes in the expression levels of pain‑associated genes in the spinal cord. A mouse model of pancreatic cancer‑induced pain was established by implanting SW 1990 cells into the pancreases of female BALB/c‑nu mice. The survival rate and body weight were measured following orthotropic transplantation...

BACKGROUND: Voriconazole has previously been associated with increased risk for cutaneous squamous cell carcinoma (SCC) in solid organ transplant recipients. Less is known about the risk in patients after hematopoietic cell transplantation (HCT). OBJECTIVE: We evaluated the effect of voriconazole on the risk for nonmelanoma skin cancer (NMSC), including SCC and basal cell carcionoma, among those who have undergone allogeneic and autologous HCT. METHODS: In all, 1220 individuals who had undergone allogeneic HCT and 1418 who had undergone autologous HCT were included in a retrospective cohort study...

BACKGROUND: Inconsistencies in outcome reporting and frequent omission of patient-centered outcomes can diminish the value of trials in treatment decision making. We identified critically important outcome domains in kidney transplantation based on the shared priorities of patients/caregivers and health professionals. METHODS: In a 3-round Delphi survey, patients/caregivers and health professionals rated the importance of outcome domains for trials in kidney transplantation on a 9-point Likert scale and provided comments...

BACKGROUND: Skin cancer is the most common malignancy after solid organ transplant and can lead to significant morbidity. The likelihood of developing squamous cell carcinomas and melanomas is 100 and 2.4 times more likely, respectively, in kidney transplant recipients when compared with the general population. There are few data regarding the assessment and influence of solid organ transplant recipient (SOTR) knowledge of skin cancer and its effect on short- and long-term awareness and behavior...

BACKGROUND: Kidney transplant recipients (KTRs) receiving the mammalian target of rapamycin inhibitor sirolimus may display a reduced risk of skin cancer development compared to KTRs receiving calcineurin inhibitors. Despite studies investigating the effects of these 2 drug classes on T cells in patient blood, the effect these drugs may have in patient skin is not yet known. METHODS: Fifteen patients with chronic kidney disease (not recipients of immunosuppressive drugs), and 30 KTRs (15 receiving a calcineurin inhibitor, and 15 receiving sirolimus) provided matched samples of blood, sun exposed (SE) and non-SE skin...

The risk of melanoma in organ transplant recipients (OTR) is increased compared with the general population. This retrospective study registered all cases of post-transplant melanoma in kidney, heart, lung, and liver transplant recipients followed in our specialized post-transplant Dermatology Clinic since 1991. The yearly prevalence of melanoma and skin carcinoma between 2000 and 2015 was computed and compared in this population. Based on another cohort of kidney transplant recipients grafted since 2005, adjusted age- and sex-standardized incidence ratio (SIR) was calculated using a renal transplantation registry...

BACKGROUND: The symmetrical immune network theory, developed in 1975, is based on the existence of specific T cell factors and hypothesizes that normal IgG immune responses comprise the production of 2 kinds of antibodies, namely antigen-specific antibodies and anti-idiotypic antibodies. OBJECTIVE: The aim of this study was to confirm the existence of specific T cells factors and to show that immunization of C3H mice with BL/6 skin or using nominal antigen for immunization (Tetanus Toxoid) induced production of antigen-specific (anti-BL/6 or antitetanus) antibodies plus anti-idiotypic antibodies (C3H anti-anti-C3H)...

The role of cutaneous viral infections in the development of non-melanoma skin cancer (NMSC), including cutaneous squamous cell carcinoma (SCC), among chronic lymphocytic leukemia (CLL) and blood and marrow transplant (BMT) patients is not established. CLL (n = 977) and BMT (n = 3587) patients treated at the Moffitt Cancer Center were included in a retrospective cohort study. Human papillomavirus (HPV) and human polyomavirus (HPyV) DNA were examined in a subset of incident SCC tumors. Five-year cumulative incidence of NMSC was 1...

DIDS is a unique form of combined immune deficiency characterized by an unusual susceptibility to cutaneous viral infections, severe allergies with eosinophilia and elevated immunoglobulin E titers, autoimmunity, and cancer. HSCT is considered the standard of care for this deadly disease. We have retrospectively analyzed the outcome of allogeneic HSCT from unrelated donors in patients with DIDS. Data from four patients, with five transplants, are presented. All patients received transplants from unrelated donors' BM, except for one patient who received a cord blood transplant...

BACKGROUND: Skin cancer occurs frequently in organ transplant patients as a result of induced immunosuppression. Most cases involve carcinomas or B-cell lymphomas induced by the Epstein Barr virus (EBV). Cutaneous T-cell lymphomas remain rare. We report a case of cutaneous T-cell lymphoma of the mycosis fungoides type in a heart transplant recipient. PATIENTS AND METHODS: A 68-year-old man who had received a heart transplant 21years earlier and was being treated with tacrolimus, mycophenolate mofetil and prednisolone had been presenting a psoriasiform rash on his trunk, limbs and head for 4years...

Cancer is one of the major causes of mortality in organ transplant patients receiving immunosuppressive regimen based on Cyclosporin A (CsA). Organ transplantation and chronic immunosuppression are typically associated with skin cancers (both squamous cell carcinoma and melanoma) and renal cell carcinoma (RCC). Recent studies have shown that in addition to its immunosuppressive effects, accounted for by the inhibition of calcineurin and the modulation of the transcriptional programme of lymphocytes, CsA also directly stimulates the growth and aggressive behaviour of various cancer cells...

Plasma cell leukemia is an uncommon, aggressive variant of leukemia that may occur de novo or in association with multiple myeloma. Leukemia cutis is the cutaneous manifestation of leukemia, and indicates an infiltration of the skin by malignant leukocytes or their precursors. Plasma cell leukemia cutis is a rare clinical presentation of leukemia. We present a man who developed plasma cell leukemia cutis in association with multiple myeloma. Cutaneous nodules developed on his arms and legs 50 days following an autologous stem cell transplant...
