Abstract
BACKGROUND Solid organ transplantation is a risk predictor for virally-mediated anal squamous intraepithelial lesions and cancer (anal disease). Precancerous squamous intraepithelial lesions can be detected by screening, and treatment may prevent cancer progression. Screening recommendations are not well defined. We aim to define prevalence and describe risk predictors for anal disease in a large population of solid organ transplant recipients. METHODS Retrospective single-center cohort analysis included solid organ transplant recipients cared for between 2001 and 2022 (N = 15 362). The cohort of recipients who developed anal disease was compared with those who did not. Greedy propensity score matching was performed for organ-specific recipients, and time-to-event analysis for the development of anal disease was performed in those with genitourinary human papilloma virus (HPV) disease versus those without. RESULTS Prevalence of anal disease was 0.6% (cancer 0.2%). The average years from transplant to the diagnosis of anal disease was 11.67. Anal disease was more common in women (68.5% versus 31.5%, P < 0.001), patients who had other HPV-related genitourinary diseases (40.4% versus 0.6%, P < 0.001), who were of younger age at transplant (39.62 versus 46.58, P < 0.001), and had increased years from transplant (17.06 versus 12.57, P < 0.001). In multivariate analysis, the odds of anal disease increased by 4% each year posttransplant. History of genitourinary HPV disease (odds ratio 69.63) and female sex (odds ratio 1.96) were the most significant risk predictors for anal disease. CONCLUSIONS The prevalence of anal cancer among solid organ transplant recipients was equal to the general population (0.2%). Due to the low prevalence of overall disease, these data suggest that anal screenings in transplant recipients should be targeted to higher-risk subsets: female recipients farther out from transplant and patients with genitourinary HPV-related diseases.

Abstract
PURPOSE OF REVIEW Skin and soft tissue infections (SSTI) in solid organ transplant (SOT) recipients may be a great challenge for clinicians caring for SOT due to the involvement of both common and opportunistic pathogens associated with a blunted immune response. The purpose of this review is to outline current literature and describe open issues on the management of SSTI in this special population. RECENT FINDINGS Clinical presentation in SOT recipients can manifest as isolated skin lesions after primary inoculation or be the sign of a disseminated infection. Tissue samples for microscopy and histopathology are crucial to making an accurate diagnosis given the nonspecific and heterogeneous appearance of skin lesions. Multidisciplinary teams are required for a comprehensive diagnosis and management. SUMMARY SSTI are frequent contributors to morbidity and mortality in SOT. Specific research focused on the clinical presentation, risk factors and management in this special population is needed.

Anogenital distribution of mucosal HPV in males and females before and after renal transplantation. Infect Dis Now 2024; 54:104830.

Abstract
INTRODUCTION Immunosuppressive drugs taken by transplant recipients may favor HPV infection at anogenital sites. HPV-type prevalence was studied in males and females before and after renal transplantation. PATIENTS AND METHODS Anal, cervical and penile samples were taken from 62 patients before transplantation and from 41 patients after transplantation. HPV DNA was investigated using the INNO-LiPA HPV genotyping extra test and HPV-type distribution determined. RESULTS Before transplantation, up to 30% of analyzed samples harbored HPV DNA, with the highest prevalence found in cervical specimens (60%). After transplantation, a trend toward HPV clearance was observed in females. By contrast, a trend toward incident infections by a wide variety of HPV genotypes at the penis and anal level was documented in men. CONCLUSION High prevalence of HPV at anogenital sites was documented before and after renal transplantation. Immunosuppressive drugs taken after transplantation may impact HPV acquisition or reactivation, especially in males. Special attention should be paid in view of preventing HPV-associated diseases in this vulnerable population.

Immunogenicity of a quadrivalent human papillomavirus vaccine in pediatric kidney and liver transplant recipients. Pediatr Transplant 2023; 27:e14476. [PMID: 36740761 DOI: 10.1111/petr.14476] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Revised: 12/22/2022] [Accepted: 01/11/2023] [Indexed: 02/07/2023]
Abstract
BACKGROUND Solid-organ transplant recipients are at increased risk of developing human papillomavirus-related diseases. METHODS To evaluate the immunogenicity of a quadrivalent vaccine, a prospective observational study included females aged 12-19 years who had received kidney or liver transplants, or were otherwise healthy volunteers. With the three-dose vaccination, serum antibodies were measured. RESULTS The study included 17 transplant recipients (seven kidney and 10 liver) and 16 healthy participants. Six of seven kidney transplant recipients were on three immunosuppressive medications, whereas 9 of the 10 liver transplant recipients were on one. For the serology within 6 months from the last vaccine dose, the geometric mean titers of human papillomavirus types 6, 11, 16, and 18 were 26.7, 8.6, 35.7, and 42.4 (kidney transplant); 579.2, 569.3, 3097.3, and 835.7 (liver transplant); and 860.5, 638.8, 4391.6, and 902.6 milli-Merck Units/ml (healthy). The seropositivity rates of kidney transplant recipients for the four serotypes ranged from 50% to 75%, while all liver transplant recipients and healthy participants had 100% seropositivity rates for all four types. While there were no statistical differences of titers between liver transplant recipients and healthy participants, the titers of kidney transplant recipients were lower than those of healthy participants for type 6 (p = .034), type 11 (p = .032), and type 16 (p = .032). CONCLUSIONS The results support the recommendation of human papillomavirus vaccination in pediatric transplant recipients given the significant risk of human papillomavirus-related diseases in this population, though immunogenicity was lower in kidney transplant recipients on multiple immunosuppressive medications.

Nailescu C, Shew ML. Human papillomavirus infection-related cancer risk for kidney transplant recipients during adult life can be reduced by vaccination during childhood and adolescence. Front Pediatr 2022; 10:1057454. [PMID: 36533243 PMCID: PMC9749905 DOI: 10.3389/fped.2022.1057454] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Accepted: 11/15/2022] [Indexed: 12/02/2022] Open
Abstract
Malignancies are found between the first three reasons of mortality in pediatric and adult kidney transplant recipients, who overall have disproportionately higher rates of cancer compared to the general population, including human papillomavirus (HPV)-related genital, anal and oropharynx region cancers. Therefore, preventing HPV in this patient population is extremely important. HPV-vaccine was demonstrated to prevent HPV infection in individuals with intact immune systems. In addition, recent data reported less precancerous HPV lesions and cervical cancers with use of HPV vaccine. Since HPV is a sexually transmitted virus that is typically acquired shortly after the onset of sexual activity, it is best to administer the HPV vaccine immunization prior to the onset of sexual activity. This article reviews the epidemiology and pathophysiology of the HPV infection, as well as its role in the development of HPV-related pre-cancerous lesions and cancers in both general population and kidney transplant recipients. The focus is on the most effective primary prophylactic strategy, which is the HPV vaccination. The particularities of HPV vaccination strategies in kidney transplant recipients are compared to the general population. In addition, the article analyzes the various causes of suboptimal HPV immunization rates in kidney transplant candidates and recipients and discusses vaccination optimization strategies that can be applied during childhood and adolescence to reduce the burden of HPV-related disease states and cancer among adult kidney transplant recipients.
