Jagdish RK, Chappity P, Lata S. Dental and ENT Evaluation Before Liver Transplantation. J Clin Exp Hepatol 2024; 14:101431. [PMID: 38745755 PMCID: PMC11090062 DOI: 10.1016/j.jceh.2024.101431] [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: 07/16/2023] [Accepted: 04/14/2024] [Indexed: 05/16/2024] Open
Abstract
The assessment of dental and ear, nose and throat (ENT) conditions holds significant importance in the pre-transplantation evaluation for individuals undergoing liver transplantation. This evaluation aims to address concerns related to dental and ENT issues both before and after liver transplantation. These concerns include the risk of sepsis, the impact of post-transplantation immunosuppression, the detection of existing malignancies, including oral potentially malignant disorders (OPMDs), and identifying any contraindications to the transplantation procedure. However, it is worth noting that there exists a notable absence of clear guidelines and protocols in the existing literature regarding this practice. Moreover, recent studies have presented conflicting results, and concerns have arisen regarding the cost-effectiveness of these evaluations. It is crucial to perform these investigations judiciously to avoid unnecessary testing burdens and delays in placing patients on waiting lists, particularly when considering live donor liver transplantation (LDLT) evaluations. A comprehensive examination of the oral and ENT regions, in conjunction with relevant laboratory tests, can play a pivotal role in identifying and managing oral and ENT diseases before the liver transplantation procedure. Timely recognition and treatment of potential issues are essential for minimizing perioperative morbidity and mortality. There is an evident need for prospective trials and studies to further explore and establish guidelines in the critical area of dental and ENT evaluation in liver transplantation recipients. Such research efforts would contribute significantly to enhancing our understanding and management of oral and ENT conditions in the pre-transplantation setting, ultimately improving patient care and outcomes.

Abstract
Individuals with chronic liver disease (CLD) have an increased risk of bleeding from thrombocytopenia and changes in hemostasis. The aim of this study was to evaluate the frequency of and the factors associated with the occurrence of bleeding in CLD patients who underwent dental surgical procedures. This was a retrospective study whose data were collected in a hospital dentistry service between 2010 and 2016. The patients were referred from the gastroenterology and liver transplantation services of a university hospital for dental treatment. The study followed the STROBE guidelines. Among the 71 surgical procedures performed, there were 17 (24%) perioperative and postoperative bleeding episodes, 14 of which were in pretransplant patients and 11 received blood transfusion before dental surgery. Individuals with a previous history of bleeding (PR = 2.67, CI = 1.07-6.67, P = 0.035) and those with a platelet count before surgery 50 × 109/l or less (PR = 7.48, CI = 1.70-32.86, P = 0.008) had a higher prevalence of perioperative and postoperative bleeding episodes than their peers without a previous history of bleeding, and those with platelet count greater than 50 × 109/l. The approach to individuals with CLD is complex and represents a challenge to the clinician. A careful anamnesis combined with laboratory screening of coagulation disorders appears to be useful to identify individuals at a major risk of bleeding. Studies identifying the predisposing factors of bleeding in CLD patients support well tolerated protocols for oral surgery in this group.

Abstract
The prevention and management of bleeding and thrombosis in patients with cirrhosis poses several difficult clinical questions. These Clinical Practice Guidelines have been developed to provide practical guidance on debated topics, including current views on haemostasis in liver disease, controversy regarding the need to correct thrombocytopenia and abnormalities in the coagulation system in patients undergoing invasive procedures, and the need for thromboprophylaxis in hospitalised patients with haemostatic abnormalities. Multiple recommendations in this document are based on interventions that the panel feels are not useful, even though widely applied in clinical practice.

Abstract
BACKGROUND Gaps of knowledge still exist about the potential association between severe thrombocytopenia and increased risk of procedure-associated bleeding in patients with liver disease. METHODS In this narrative review, we aimed at examining the association between procedure-related bleeding risk and platelet count in patients with cirrhosis and severe thrombocytopenia in various settings. We updated to 2020 a previously conducted literature search using MEDLINE/PubMed and EMBASE. The search string included clinical studies, adult patients with chronic liver disease and thrombocytopenia undergoing invasive procedures, any interventions and comparators, and haemorrhagic events of any severity as outcome. RESULTS The literature search identified 1276 unique publications, and 15 studies met the inclusion criteria and were analysed together with those identified by the previous search. Most of the new studies included in our analysis did not assess the association between post-procedural bleeding risk and platelet count alone in patients with chronic liver disease. Furthermore, some results could have been biased by prophylactic platelet transfusions. A few studies found that severe thrombocytopenia may be predictive of bleeding following percutaneous liver biopsy, dental extractions, percutaneous ablation of liver tumours and endoscopic polypectomy. CONCLUSIONS Currently available literature cannot support definitive conclusions about the appropriate target platelet counts to improve the risk of bleeding in cirrhotic patients who underwent invasive procedures; moreover, it showed enormous variability in the use of prophylactic platelet transfusions.

Assessment of laboratory tests and intraoperative bleeding in patients with liver cirrhosis undergoing tooth extractions. Oral Surg Oral Med Oral Pathol Oral Radiol 2021; 133:148-155. [PMID: 34275775 DOI: 10.1016/j.oooo.2021.05.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 05/21/2021] [Accepted: 05/24/2021] [Indexed: 12/19/2022]
Abstract
OBJECTIVES The objective of this study was to quantify intraoperative bleeding in patients with cirrhosis and correlate it with clinical characteristics and laboratory coagulation tests. STUDY DESIGN A case-control study was carried out with 74 patients with cirrhosis who were submitted to preoperative coagulation tests (complete blood count, platelet count, prothrombin time/international normalized ratio, thrombin time, activated partial thrombin time, platelet aggregation, fibrinogen, protein C, protein S, antithrombin, and von Willebrand factor level and activity). The levels of nitrogen compounds that can affect the platelet function were determined in saliva and blood by using automated enzymatic-colorimetric assays. RESULTS Patients with cirrhosis had changes in almost all coagulation tests. The average volumes of intraoperative bleeding and blood lost per minute in the study group (5.36 mL/min and 0.19 mL/min, respectively) were greater than those in the control group (3.05 mL/min and 0.11 mL/min, respectively; P < .05). In the control group, ascites (P = .012) and presence of periapical lesion (0.034) were positively correlated with bleeding (mL/min). With regard to coagulation tests and nitrogen compounds, only a positively moderate correlation with the platelet aggregation test was observed. CONCLUSIONS No patients had hemorrhagic events and it was not possible to correlate a greater amount of bleeding with coagulation tests or nitrogen compounds in the study group.

Abstract
BACKGROUND The liver is responsible for the production of almost all coagulation factors, but does this indicate a risk of developing unusual bleeding in patients with liver cirrhosis during dental surgery? TYPES OF STUDIES REVIEWED In this systemic review, the authors followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist and performed a search of PubMed, Latin American and Caribbean Health Sciences Literature, Web of Science, Scopus, and Cochrane databases. RESULTS Seven studies met the inclusion criteria. The sample sizes ranged from 23 through 318 participants, number of extracted teeth ranged from 62 through 1,183, platelet count ranged from 16,000 through 216,000 per cubic milimeter, and the international normalized ratio was less than 4. The prevalence of hemorrhagic events in the studies ranged from 0% through 8.9%, and almost all were controlled with local hemostatic measures. CONCLUSIONS AND PRACTICAL IMPLICATIONS During dental treatment, patients with liver cirrhosis have a low bleeding risk in spite of the decreased number of platelets and increased international normalized ratio.

Abstract
Little is known about the prevention and management of acquired coagulopathies, such as those affecting cirrhotic patients. The objective of this analytic retrospective observational study was to evaluate patients on the liver transplant waiting list according to the following outcomes: (1) presence of unusual intraoperative bleeding (>10min after routine haemostatic procedures); and (2) presence of postoperative haemorrhagic complications. The outcomes were analysed according to clinical and laboratory variables. A total of 190 visits were performed for extraction of 333 teeth (ranging from 1 to 9 teeth per visit), with platelet count ranging from 16,000 to 216,000 and international normalized ratio (INR) below 3. Twelve cases (6.31%) had unusual intraoperative bleeding and 12 had postoperative haemorrhagic complications. All the events were controlled by local measures. Intraoperative bleeding was associated with low count of platelets (P=0.026). However, this counting could explain only 16% (adjusted R2=0.16) of the cases of bleeding (P=0.44), meaning that platelet function changes might be involved. Our results show that cirrhotic patients presenting platelet count above 16,000 and INR below 3 need no previous blood transfusion, with local measures being enough to manage haemorrhagic events.

Abstract
PURPOSE Cirrhotic patients awaiting liver transplantation require eradication of infectious oral foci to prevent septic episodes after transplantation; however, cirrhosis can hinder hemostasis and can result in severe bleeding. The present study assessed the bleeding risk factors connected with the clinical history of these patients and the characteristics of the extractions. MATERIALS AND METHODS We retrospectively analyzed 1183 extractions in 318 patients, including 47 with severe end-stage liver disease who were outside of our intention-to-treat bracket (ie, platelet count [PLT] >40 × 103/μL and international normalized ratio [INR] <2.5). Follow-up examinations included inspection of the oral cavity on the first, third, and seventh days, with reparatory surgery in the case of severe bleeding. Continuous variables were compared using the Mann-Whitney U and Kruskal-Wallis tests, and categorical variables were compared using Fisher's exact test. Binary logistic regression analysis was also performed. RESULTS Within the intention-to-treat bracket, 1 of the 271 patients (0.4%) required surgical repair. The bleeding rate for an INR of 2.5 or more was significantly greater than that for a PLT of 40 × 103/μL or less (4 of 10 [40%] versus 2 of 34 [6%]; P = .02]. All 3 patients with both an INR of 2.5 or more and a PLT of 40 × 103/μL or less exhibited severe bleeding. No significant association between the occurrence of bleeding with either liver disease etiology or the number of molars extracted was found. No patient required hospitalization. CONCLUSIONS Patients with a PLT greater than 40 × 103/μL and an INR of less than 2.5 can be considered relatively low-risk patients. However, an INR of 2.5 or more and, to a minor degree, a PLT of 40 × 103/μL or less represent significant risk factors.

Abstract
Periodontitis is an oral disease that is highly prevalent worldwide, with a prevalence of 30–50% of the population in developed countries, but only ~10% present with severe forms. It is also estimated that periodontitis results in worldwide productivity losses amounting to ~54 billion USD yearly. In addition to the damage it causes to oral health, periodontitis also affects other types of disease. Numerous studies have confirmed the association between periodontitis and systemic diseases, such as diabetes, respiratory disease, osteoporosis and cardiovascular disease. Increasing evidence also indicated that periodontitis may participate in the progression of liver diseases, such as non-alcoholic fatty liver disease, cirrhosis and hepatocellular carcinoma, as well as affecting liver transplantation. However, to the best of our knowledge, there are currently no reviews elaborating upon the possible links between periodontitis and liver diseases. Therefore, the current review summarizes the human trials and animal experiments that have been conducted to investigate the correlation between periodontitis and liver diseases. Furthermore, in the present review, certain mechanisms that have been postulated to be responsible for the role of periodontitis in liver diseases (such as bacteria, pro-inflammatory mediators and oxidative stress) are considered. The aim of the review is to introduce the hypothesis that periodontitis may be important in the progression of liver disease, thus providing dentists and physicians with an improved understanding of this issue.

Abstract
Patients with cirrhosis present with hemostatic alterations secondary to reduced availability of pro-coagulant and anti-coagulant factors. The net effect of these changes is a rebalanced hemostatic system. The Italian Association of the Study of the Liver (AISF) and the Italian Society of Internal Medicine (SIMI) promoted a consensus conference on the hemostatic balance in patients with cirrhosis. The consensus process started with the review of the literature by a scientific board of experts and ended with a formal consensus meeting in Rome in December 2014. The statements were graded according to quality of evidence and strength of recommendations, and approved by an independent jury. The statements presented here highlight strengths and weaknesses of current laboratory tests to assess bleeding and thrombotic risk in cirrhotic patients, the pathophysiology of hemostatic perturbations in this condition, and outline the optimal management of bleeding and thrombosis in patients with liver cirrhosis.

Abstract
PURPOSE To characterize bleeding risk and management of bleeding in thrombocytopenic patients undergoing dental extraction. MATERIALS AND METHODS This retrospective cohort study included 68 patients with hematologic disease and concomitant thrombocytopenia undergoing dental extractions. The inclusion criterion was a platelet count of 100,000/μL or less at the time of consultation or extraction. Patients using anticoagulation therapy were excluded from the study. Predictors measured were age, gender, platelet count, platelet transfusion before or during surgery, local hemostatic measurements at the time of surgery (absorbable hemostat or antifibrinolytic rinse), number of teeth extracted, diagnosis, and extraction type. The primary outcome was postoperative bleeding requiring intervention. A secondary outcome was surgical site infection. Descriptive and bivariate statistics were computed and the P value was set at .05. No logistic regression was used based on the distribution of outcomes. RESULTS Sixty-eight patients underwent extraction of 200 teeth. Five (7.4%) had postoperative bleeding that was always controlled with routine intervention. Mean platelet count was 44,647/μL. Bleeding was more frequent with lower platelet levels (P = .048). Thirty-two patients received platelet transfusion and 26 received local measures. Platelet transfusion and local hemostatic measures had no effect on bleeding outcomes. CONCLUSION Surgical and routine extractions are safe procedures in patients with thrombocytopenia, and postoperative bleeding is typically well handled with simple local measures. The benefits of pre- or intraoperative platelet transfusion are unclear in this population. Likewise, the benefit of prophylactic local hemostatic measures is unclear and should be based on the surgeon's discretion and experience.

Abstract
Liver transplantation has become a standard treatment for end-stage liver disease and
the number of recipients has grown rapidly in the last few years. Dental care during
pre-transplant workup is important to reduce potential sources of infection in the
drug-induced immunosuppression phase of liver transplantation.

Postoperative bleeding after dental extraction in liver pretransplant patients. J Oral Maxillofac Surg 2012; 70:e177-84.

Abstract
PURPOSE The aim of this prospective observational study was to evaluate the incidence of postoperative bleeding after dental extraction in candidates for liver transplantation and the efficacy of the association of tranexamic acid and absorbable hemostatic sponges. PATIENTS AND METHODS All individuals referred for oral health evaluation requiring extraction were considered in this study. Patients were included in the analysis when the blood examinations showed a platelet count of 30,000/mm(3) or greater and an international normalized ratio (INR) of 3.0 or less. In group 1 local pressure was applied by use of gauze soaked with tranexamic acid, and in group 2 gauze without tranexamic acid was used. Absorbable hemostatic sponges and cross sutures were used as a standard hemostatic measure. RESULTS In the 23 patients included in this study, 84 simple extractions were performed during 35 dental surgical procedures. The main preoperative blood tests found the following: a mean hematocrit level of 34.54% (SD, 5.84%; range, 21.7%-44.4%), platelet counts from 31,000/mm(3) to 160,000/mm(3), and a mean INR of 1.50 (SD, 0.39; range, 0.98-2.59). Postoperative bleeding occurred during only 1 procedure (2.9%), and local pressure with gauze was effective for achieving hemostasis. No statistically significant difference in the time to hemostasis was found between the 2 groups. CONCLUSIONS This study found a low risk of bleeding for tooth extractions in patients with liver cirrhosis, INRs of 2.50 or less, and platelet counts of 30,000/mm(3) or greater. Blood transfusions were not needed, and in the case of postoperative bleeding, the use of local hemostatic measures was satisfactory.

Abstract
Elimination of dental infection foci has been recommended before liver transplantation (LT) because lifelong immunosuppression may predispose to infection spread. Association between pre-LT oral health and the aetiology and severity of chronic liver disease (CLD) was investigated retrospectively. A total of 212 adult patients (median age 51.1) who had received LT during 2000-2006 in Finland were included. Their oral health had been pre-operatively examined. Patients were divided into seven different CLD groups. Common indications for LT were primary sclerosing cholangitis (PSC 25.5%), alcohol cirrhosis (ALCI 17.5%) and primary biliary cirrhosis (PBC 14.6%). Patients were also categorized by the Model for End stage Liver Disease (MELD) scoring system. Medical, dental and panoramic jaw x-ray data were analysed between groups. PBC patients had the lowest number of teeth with significant difference to PSC patients (19.7 vs. 25.6, P < 0.005, anova, t-test). ALCI patients had the highest number of tooth extractions with significant difference in comparison to PSC patients (5.6 vs. 2.5, P < 0.005). Lower MELD score resulted in fewer tooth extractions but after adjusting for several confounding factors, age was the most important factor associated with extractions (P < 0.005). The aetiology of CLD associated with the oral health status and there was a tendency towards worse dental health with higher MELD scores.
