Intra-host changes in Kaposi sarcoma-associated herpesvirus genomes in Ugandan adults with Kaposi sarcoma. PLoS Pathog 2021; 17:e1008594. [PMID: 33465147 PMCID: PMC7845968 DOI: 10.1371/journal.ppat.1008594] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Revised: 01/29/2021] [Accepted: 11/24/2020] [Indexed: 12/14/2022] Open
Abstract
Intra-host tumor virus variants may influence the pathogenesis and treatment responses of some virally-associated cancers. However, the intra-host variability of Kaposi sarcoma-associated herpesvirus (KSHV), the etiologic agent of Kaposi sarcoma (KS), has to date been explored with sequencing technologies that possibly introduce more errors than that which occurs in the viral population, and these studies have only studied variable regions. Here, full-length KSHV genomes in tumors and/or oral swabs from 9 Ugandan adults with HIV-associated KS were characterized. Furthermore, we used deep, short-read sequencing using duplex unique molecular identifiers (dUMI)–random double-stranded oligonucleotides that barcode individual DNA molecules before library amplification. This allowed suppression of PCR and sequencing errors to ~10−9/base as well as afforded accurate determination of KSHV genome numbers sequenced in each sample. KSHV genomes were assembled de novo, and rearrangements observed were confirmed by PCR and Sanger sequencing. 131-kb KSHV genome sequences, excluding major repeat regions, were successfully obtained from 23 clinical specimens, averaging 2.3x104 reads/base. Strikingly, KSHV genomes were virtually identical within individuals at the point mutational level. The intra-host heterogeneity that was observed was confined to tumor-associated KSHV mutations and genome rearrangements, all impacting protein-coding sequences. Although it is unclear whether these changes were important to tumorigenesis or occurred as a result of genomic instability in tumors, similar changes were observed across individuals. These included inactivation of the K8.1 gene in tumors of 3 individuals and retention of a region around the first major internal repeat (IR1) in all instances of genomic deletions and rearrangements. Notably, the same breakpoint junctions were found in distinct tumors within single individuals, suggesting metastatic spread of rearranged KSHV genomes. These findings define KSHV intra-host heterogeneity in vivo with greater precision than has been possible in the past and suggest the possibility that aberrant KSHV genomes may contribute to aspects of KS tumorigenesis. Furthermore, study of KSHV with use of dUMI provides a proof of concept for utilizing this technique for detailed study of other virus populations in vivo. Kaposi sarcoma (KS) is a leading cancer in sub-Saharan Africa and in persons with HIV co-infection. Kaposi sarcoma-associated herpesvirus (KSHV, also referred to as human herpesvirus-8, or HHV-8) is the etiologic agent of KS, but the factors that contribute to the development of KS, which occurs in only a small subset of infected individuals, remain largely unknown. While strain differences or mutations in other tumor viruses are known to affect the risk and progression of their associated cancers, whether genetic variation in KSHV is important to the natural history of KS is unclear. Most studies of KSHV diversity have only characterized ~4% of its 165-kb genome, and the observed variation in some studies is likely to have been impacted by PCR or cloning artifacts. To precisely define genomic diversity of KSHV in vivo, we evaluated full-length viral genomes (except the internal repeat regions) using a technique that greatly lowers sequencing error rates and thus measures genomic diversity much more accurately than previous studies. In addition, we extended our analyses to look for potential tumor-specific changes in the KSHV genomes by examining viruses in both tumor and non-tumor tissues. To these ends, we performed highly sensitive, single-molecule sequencing of whole KSHV genomes in paired KS tumors and oral swabs from 9 individuals with KS. We found that KSHV genomes were virtually identical within the 9 individuals, with no evidence of quasispecies formation or multi-strain infection. However, KSHV genome aberrations and gene-inactivating mutations were found to be common in KS tumors, often impacting the same genes and genomic regions across individuals. Whether theses mutations influence KS tumorigenesis or result from genomic instability commonly found in tumors warrants further study. Lastly, aberrant KSHV genomes were found to be shared by distinct tumors within individuals, suggesting the capacity of KS tumor cells to metastasize and seed new lesions.

Periodontal disease and detection of human herpesviruses in saliva and gingival crevicular fluid of chronic kidney disease patients. J Periodontol 2020; 91:1139-1147. [PMID: 32012280 DOI: 10.1002/jper.19-0583] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Revised: 12/04/2019] [Accepted: 12/30/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND Patients with chronic kidney disease (CKD) have inability to maintain the normal levels of protein metabolism products, blood pressure and hematocrit. Periodontal disease involves an inflammatory destructive process. Identification of opportunistic viruses is extremely important as they are associated with co-morbidities. The objective of this study was to analyse the presence of human herpesviruses in saliva and gingival crevicular fluid (GCF) from patients with CKD. METHODS One hundred and thirty one individuals were divided depending on the stage of CKD: Group 1 (clearance of creatinine > 75 mL/min) patients with no renal disease (n = 24); Group 2 (clearance of creatinine of 11-75 mL/min) patients with renal disease (n = 67); Group 3 (clearance of creatinine < 10 mL/min) patients on hemodialysis (n = 40). The parameters of periodontal disease were evaluated. The viral detection was assessed by PCR. RESULTS considering the three groups, the prevalence of herpes simplex virus 1 (HSV-1) were 9% in saliva and 5% in GCF; Epstein-Barr virus 36% in saliva and 39% in GCF; human cytomegalovirus (HCMV) 11% in GCF; varicella zoster virus 6% in saliva and 3% in GCF; of human herpesvirus-6 (HHV-6) 6% in saliva and 2% in GCF; and HHV-7 44% in saliva and 8% in GCF. Of these patients, 46.48% presented with severe periodontitis. A statistically significant association between HSV-1 and HCMV was found in hemodialysis patients and severe periodontitis was also more frequent among them. CONCLUSION These findings show the importance of evaluating the periodontal disease and detecting herpesviruses in patients with CKD as the inflammatory process observed in these clinical conditions may worsen the course of both periodontal disease and CKD.

Abstract
The incidence of Kaposi's sarcoma (KS) is increasing among renal transplant recipients. Patients with end-stage renal disease (ESRD) are immunocompromised and are candidates for renal transplantation, but HHV8 seroprevalence in ESRD patients has not been well documented. A cross-sectional study of 286 ESRD patients and 281 matched subjects without kidney disease was conducted at the First People's Hospital of Huzhou, Zhejiang province to explore the epidemiologic features of HHV8 among ESRD patients in China. Blood samples were collected and HHV8 antibodies and serologic indices were measured. The seroprevalence of HHV8 was 15.3% for ESRD patients and 8.9% for the comparison group. A significant difference in the geometric mean titer (GMT) of the HHV8 antibodies was detected between ESRD patients and the comparison group (617.1 vs 291.7; P = 0.042). The average level of hemoglobin was 11.56 ± 1.78 g/dL for the ESRD group and 13.73 ± 1.42 g/dL for the comparison group, (P > 0.05). Multiple linear regression revealed a negative association between HHV8 infection and plasma hemoglobin concentration (β = -0.682, P = 0.036). We found a higher HHV8 prevalence and a higher level of HHV8 antibody GMT in ESRD patients than the comparison group, which indicate a high risk of posttransplantation KS.

Abstract
OBJECTIVE To describe the shedding profile of human herpesviruses in the saliva of renal transplant recipients. METHODS This is a prospective case-control study of 50 renal transplant recipients and control group of 50 individuals (non-transplanted and immunocompetent). Mouthwash samples were collected via oral rinse and then submitted to screening for the presence of eight types of herpesviruses by using multiplex PCR. Fisher's exact, chi-square, and Student t tests were used for statistical analysis, and the significance level was set at 5%. RESULTS The mean age of the study group was 49.42 ± 12.94 years, 28/50 (56%) were female, and the time elapsed after transplantation was 68.20 ± 67.19 months. Herpes simplex virus 1 (HSV-1) (P = 0.025) and Epstein-Barr virus (EBV) (P = 0.024) were, statistically, more excreted in the saliva of renal transplant recipients compared to control group. Gender (P = 1.00) and age (P = 0.563) did not influence the salivary shedding of herpesviruses in renal transplant recipients. Individuals who excreted varicella-zoster virus in saliva had a shorter mean time of transplantation (22:00 + 2.82 months) (P < 0.001). CONCLUSION Renal transplant recipients excreted herpesviruses more often than controls, especially HSV-1 and EBV, with salivary shedding of herpesviruses being more frequent in patients with recent kidney transplantation. CLINICAL RELEVANCE The present findings support other longitudinal studies evaluating the relationship between oral shedding of human herpesviruses and clinical presence of active infection and renal transplant failure.

Abstract
PURPOSE OF REVIEW Ocular surface malignancy is a serious complication in HIV infection, but can often result in successful treatment if diagnosed appropriately. In the literature, most reviews focus on information for the ophthalmic community. Here, we provide a review of the literature with the pertinent information for the nonophthalmologist, as they are the first point of contact for most HIV patients. RECENT FINDINGS Ocular surface squamous neoplasia (OSSN) is the most common nonpigmented ocular surface malignancy. It can be treated well with surgery or topical chemotherapy, the newest method of treatment. When presenting in young patients, a high percentage have been found to be HIV positive. Kaposi's sarcoma is an AIDS-defining malignancy and critical to diagnose. It cannot be cured, but treatment is effective for keeping it controlled. Conjunctival lymphoma can be recognized with the salmon patch appearance. External beam radiation, systemic chemotherapy, and intralesional injections are the mainstays of treatment. SUMMARY Ocular surface malignancy manifests significantly in the HIV population. OSSN, Kaposi's sarcoma and conjuctival lymphoma all have different clinical presentations. The capacity of the managing physician to recognize these tumours and refer to an ophthalmologist is essential for appropriate treatment.
