Evaluation of the correlation between oral infections and systemic complications in kidney transplant patients: a retrospective pilot study. BMC Oral Health 2022; 22:530. [PMID: 36424574 PMCID: PMC9685840 DOI: 10.1186/s12903-022-02590-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Accepted: 11/14/2022] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Data regarding the efficacy of the dental clearance required prior to kidney transplantation (KT) for preventing post-transplant complications is controversial. The aim of this retrospective study was to investigate a possible correlation between any untreated oral infectious foci and the onset of systemic complications in KT patients. METHODS Patients scheduled for regular check-ups during the post-transplant period were visited at the C.I.R. Dental School in Turin, Italy. Patients were asked to bring orthopantomography (OPT) acquired prior to transplantation to compare the possible presence of untreated infectious foci at the time of transplantation with the time of their post-transplant visit. Patients were then divided, according to the evaluation of the OPT obtained prior to the transplantation, into two groups according to their dental status prior to the transplant. "Group Infected" was comprised of patients with no dental clearance, and "Group Clear" included patients with dental clearance. The medical records were then retrospectively reviewed for the evaluation of any systemic complications that occurred after transplantation. The following medical complications were considered: fever, pneumonia, urinary tract infections, systemic infections, kidney rejection, and death. Complications were divided in two groups: early complications, which occurred within 100 days of transplantation, and late complications, which occurred more than 100 days after transplantation. RESULTS A total of 77 patients were enrolled in the study. Group Infected was composed of 19 subjects (25%), while Group Clear was composed of 58 patients (75%). In Group Infected, 13 (68%) patients developed complications within 100 days of transplantation, and 11 (58%) did so after 100 days. In Group Clear, 31 (53%) patients had complications within 100 days of the transplant, and 23 (40%) did after 100 days. Patients in Group Infected had a statistically significant increase in episodes of fever (p = 0.03), compared to Group Clear, with a higher relative risk (RR) of 3.66 in the first 100 days after transplantation. CONCLUSION Within the limitations of the present retrospective pilot study, and based on the results, a correlation between the absence of dental clearance prior to KT and a higher RR of developing a fever within the first 100 days post transplantation was highlighted. The present results encourage doctors to continue research on the topic, which remains controversial. Further prospective studies are required to confirm the results of the present study.

Abstract
AIMS This study aims to know whether poor oral health increases the risk of acute rejection and hospitalization in kidney allograft recipients. METHODS AND RESULTS This is a prospective cohort study. The same dentist followed participants for 2 months after renal transplant for monitoring oral health (clinical evaluation, DTMF index, and CPITN index), signs of graft rejection, infection, and hospitalization. We compiled rates and reasons for hospital readmission or extended hospital stay. The CPITN had a mean score of 0.38 ± 0.71, increasing to 0.90 ± 0.84, 60 days after transplant (P < .001). No one rejected the graft in the period of study. Patients with older age (P = .009; OR: 1.07; CI 95% 1.01-1.12) were at higher risk of hospitalization at each year of age and patients presenting pretransplant dental focus (P = .001; OR: 7.23; CI 95% 2.13-24.56) had 7.23 times more chance to be hospitalized in the first 2 months after the transplant. One participant was hospitalized due to acute foci of dental infection. CONCLUSION There was an association between dental focus and hospital readmission/stay. However, our methods do not provide conclusive proof of causality. Hospitalization due to acute dental infection was rare.

Abstract
OBJECTIVE Poor dental status is known to cause infections in severely sick and in elderly patients. In patients awaiting lung transplantation, rigorous dental treatment is a common prerequisite, although evidence-based data are lacking with regard to extent, necessity and effect on post-transplantation infectious status. MATERIALS AND METHODS In the present retrospective study, dental status [dental history (missing teeth, caries, tooth restorations and extractions, prevalence of periodontitis) and dental treatment prior transplantation] was assessed in 85 lung transplant candidates at the University Hospital of Freiburg, Germany and evaluated for infectious foci in the first 3 years following transplantation. RESULTS Forty-nine patients got transplanted in the observed timespan. Total tooth count differed significantly between chronic obstructive pulmonary disease (16 ± 9), pulmonary fibrosis (22 ± 7) or cystic fibrosis (30 ± 3) patients prior transplantation (P > 0.001). Periodontitis prevalence yielded no difference and was mainly not treated prior transplantation. No dental-related infectious focus could be diagnosed post-transplantation. However, 15% of post-transplantation infections were of unknown focus, and infection rate was increased in year 2 post-transplantation in patients without periodontitis. CONCLUSION No clearly defined dental foci were registered following transplantation. This raises the question of whether current dental treatment in these highly compromised patients is too rigorous with regard to tooth extractions. However, no focus could be detected in 15% of the registered infections. Therefore, controversially, post-transplantation dental care could also be insufficient with regard to undertreated periodontitis.

Abstract
Aim: The purpose of this study was to investigate the prevalence of apical periodontitis (AP) and endodontic treatment in liver transplant candidates and control healthy subjects.
Material and Methods: A descriptive cross-sectional study. Forty two liver transplant candidates (LTC) (study group) and 42 control subjects. Digital panoramic radiographs where used. Periapical status was scored according to the periapical index (PAI). Results were analysed statistically using the Chi-squared test and logistic regression.
Results: Radiographic signs of AP in one or more teeth was found in 79% of patients in the study group and in 50% of control subjects (p = 0.008; OR = 3.7; C. I. 95% = 1.4 - 9.5). One or more root-filled teeth (RFT) were found in 19% and 62% of study and control subjects, respectively (p = 0.0001; OR = 0.14; 95% C. I. = 0.05 - 0.38). Among LTC patients 14.7% of the teeth had AP, whereas in the control subjects 4.2% of teeth were affected (p= 0.0002). The percentage of RFT in the study and control groups was 1.5% and 6.8%, respectively (p = 0.0002). Conclusions: Liver transplant candidates have significantly higher prevalence of radiographic periapical lesions and lower frequency of RFT than controls healthy subjects.

Abstract
OBJECTIVE The significant number of complications in kidney graft recipients can not be easily explained. The paper assesses whether poor oral health increases the risk of acute rejections and hospitalizations in kidney allograft recipients. MATERIALS AND METHODS Ninety-one kidney transplant recipients were divided into three sub-groups according to post-transplant time (< 1, 1-5 and > 5 years). Dental examination evaluated oral hygiene index (OHI-S) and Community Periodontal Index of Treatment Needs (CPITN), which were correlated with the occurrence of post-transplant complications. RESULTS Within the first year after transplantation the indicators of the increased risk of hospitalizations and acute rejection episodes was the OHI-S (hazard ratio 1.02 and 1.11, respectively), also CPITN score correlated with acute rejections (R = 0.82, p < 0.01). CONCLUSION The neglect in oral health is associated with the increased risk of clinical complications within first year after kidney transplantation.

Abstract
Oral manifestations of renal disease are common. They may present as unique signs of multi-system disease affecting the kidneys (such as vasculitis), or as common oral pathologies found at an increased prevalence in patients with end-stage renal disease. Despite more oral and dental disease in patients on renal replacement therapy, attendance at dental clinics is infrequent, and physician awareness of the problem is low. In our short review, aimed at renal, transplant, and general physicians, we discuss the link between clinical changes in the mouth and multi-systemic disease involving the kidney. We suggest a standardized approach to oral examination to increase diagnostic yield and discuss common oral complications in patients on dialysis or successfully transplanted. Finally, we suggest potential treatments for oral disease that nephrologists might safely institute.

Abstract
A prerequisite dental evaluation is usually recommended for potential organ transplant candidates. This is based on the premise that untreated dental disease may pose a risk for infection and sepsis, although there is no evidence that this has occurred in organ transplant candidates or recipients. The purpose of this study was to assess the prevalence of dental disease and oral health behaviors in a sample of liver transplant candidates (LTCs). Oral examinations were conducted on 300 LTCs for the presence of gingivitis, dental plaque, dental caries, periodontal disease, edentulism, and xerostomia. The prevalence of these conditions was compared with oral health data from national health surveys and examined for possible associations with most recent dental visit, smoking, and type of liver disease. Significant risk factors for plaque-related gingivitis included intervals of more than 1 yr since the last dental visit (P = 0.004), smoking (P = 0.03), and diuretic therapy (P = 0.005). Dental caries and periodontal disease were also significantly associated with intervals of more than 1 yr since the last dental visit (P = 0.004). LTCs with viral hepatitis or alcoholic cirrhosis had the highest smoking rate (78.8%). Higher rates of edentulism occurred among older LTCs who were less likely to have had a recent dental evaluation (mean 88 months). In conclusion, intervals of more than 1 yr since the last dental visit, smoking, and diuretic therapy appear to be the most significant determinants of dental disease and the need for a pretransplantation dental screening evaluation in LTCs. Edentulous patients should have periodic examinations for oral cancer.

Abstract
The present article reviews, in detail, the current knowledge of the oral and dental aspects of chronic renal failure (CRF). Worldwide, increasing numbers of persons have CRF; thus, oral health care staffs are increasingly likely to provide care for patients with such disease. Chronic renal failure can give rise to a wide spectrum of oral manifestations, affecting the hard or soft tissues of the mouth. The majority of affected individuals have disease that does not complicate oral health care; nevertheless, the dental management of such individuals does require that the clinician understand the multiple systems that can be affected. The clinician should also consider the adverse side-effects of drug therapy and appropriate prescribing, in view of compromised renal clearance.

Abstract
Patients who have undergone organ transplantation can present with a variety of oral lesions that appear to be related either directly to their medication or arise as a consequence of drug-induced immunosuppression. Such lesions include hairy leukoplakia, an increased propensity to both fungal and viral infections and a high incidence of malignant change, especially lip cancer. Cyclosporin remains the immunosuppressant of choice in most transplant patients. Gingival overgrowth is the main unwanted oral effect associated with cyclosporin. Some 30% of dentate transplant experience this problem, which is further compounded by concomitant medication with a calcium channel blocker. This review appraises the various oral problems that can arise in this group of patients and emphasises the importance of regular oral screening and the establishment of links with the various transplant teams.

Abstract
This review considers the periodontal problems of renal transplant patients with particular reference to their drug therapy and the pretransplant uremia. It would appear that either disease- or drug-induced immunosuppression affords the renal transplant patient a degree of "protection" against periodontal breakdown. However, of more significance to the periodontologist is the problem of drug-induced gingival overgrowth with reference to both cyclosporin and nifedipine. Approximately 30% of dentate renal transplant patients medicated with cyclosporin alone experience significant gingival overgrowth which requires surgical excision. This figure increases to 40% when patients are medicated with both drugs. The pathogenesis of this unwanted effect is uncertain and the relationship between the expression of gingival overgrowth and various periodontal or pharmacokinetic variables remains a contentious issue. Clinical measures to prevent the occurrence of either cyclosporin- or nifedipine-induced gingival overgrowth are unsatisfactory.

Abstract
The same basic principles of dental management of the immunocompromised patient apply to patients receiving cardiac transplants: preimmunosuppressive therapy examination and elimination of all existing and potential sources of infection; counseling regarding the importance of meticulous oral hygiene obviating further medical complications; and frequent oral health assessments for interception of emerging oral problems, maintenance, and reinforcement of good oral care. Dental practitioners familiar with the more numerous patients with renal transplants will find differing therapy complications secondary to immunosuppression and maintenance drug regimens. The dental approach to the candidate for a cardiac transplant will differ in degree of morbidity and complexity of delivering necessary oral care before transplantation.
