[PMID: 37762719 PMCID: PMC10531646 DOI: 10.3390/jcm12185777] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 08/21/2023] [Accepted: 08/29/2023] [Indexed: 09/29/2023] Open
Abstract
Lichen planus (LP) is a chronic, inflammatory mucocutaneous disorder associated with systemic diseases such as hepatitis C (HCV). The objective of this study is to evaluate the association between LP and HCV bidirectionally through a systematic review and meta-analysis. A comprehensive search of studies published was performed in the databases of PubMed, Embase, and Web of Science. Out of 18,491 articles, 192 studies were included. The global prevalence of HCV positive (HCV+) in LP patients registered from 143 studies was 9.42% [95% confidence interval (CI), 7.27-11.58%], and from these, 84 studies showed HCV+ 4-fold more frequent in LP than a control group (OR, 4.48; 95% CI, 3.48-5.77). The global prevalence of LP in patients HCV+ recorded from 49 studies was 7.05% (95% CI, 4.85-9.26%), and from these, 15 registered a 3-fold more LP in HCV (OR, 3.65; 95% CI, 2.14-6.24). HCV+ in LP patients showed great geographic variability (OR, 2.7 to 8.57), and the predominantly cutaneous location was higher (OR, 5.95) than the oral location (OR, 3.49). LP in HCV+ patients was more frequent in the Eastern Mediterranean (OR, 5.51; 95% CI, 1.40-15.57). There is a higher prevalence of HCV+ in LP and vice versa than in the control group, especially in certain geographical areas that should be taken into consideration when doing screening in countries with an upper prevalence of HCV among the general population.

J Viral Hepat 2021; 28:809-816. [PMID: 33550705 DOI: 10.1111/jvh.13481] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Accepted: 01/23/2021] [Indexed: 12/09/2022]
Abstract
Hepatitis B virus (HBV) infection has been proposed to play a role in the development of Sjögren's syndrome. However, to date, there are no reports on the risk of SS in HBV-infected patients following nucleos(t)ide analogue therapy. Due to Taiwan has higher prevalence of HBV infection and therapy was well recorded in the Taiwan's single-payer national health insurance database, we hypothesized that a long-term retrospective analysis of the risk of Sjögren's syndrome in HBV-infected patients following nucleotide therapy will increase our understanding of Sjögren's syndrome development following HBV infection. We identified 26,147 adults diagnosed with HBV infection between 1997 and 2012 in claims data. Finally, a total of 3268 HBV-infected patients who ever received nucleotide therapy (treated cohort) were frequency-matched on age and sex at 1:4 ratios to select a control group of 13,072 counterparts without therapy (untreated cohort). To identify Sjögren's syndrome risk, competing risk analysis adjusted for all covariates was performed. The risk was significantly lower in the treated cohort (15-year cumulative incidence, 2.4%; 95% confidence interval [CI], 1.4%-3.7%) than in the untreated cohort (7.1%; 95% CI, 2.5%-15.2%) (p = .015), and the adjusted HR was 0.6 (95% CI, 0.41-0.88; p = .009). Multivariable stratified analysis further verified the consistent associations between nucleoside therapy and risk reduction of Sjögren's syndrome across all strata. Our finding suggests that HBV infection treated with nucleotides is associated with lower risk of Sjögren's syndrome, implying a potential role of HBV infection in the development of Sjögren's syndrome.

Abstract
In Japan, the method of treatment for hepatitis is well established due to the high rates of hepatitis C. However, the identification of patients with hepatitis who do not receive appropriate treatment poses a major problem. Some patients with this disease may need to consult with a dentist due to the development of extrahepatic manifestations, such as lichen planus, in the oral cavity. Alternatively, the dentist might discover patients with untreated hepatitis C and hepatitis B during routine dental examination. In such cases, the patient should be referred to a hepatologist for further examinations and treatment. Thus, dentists are required to act as 'gatekeepers of hepatitis'. Furthermore, Japanese dentists need to increase hepatitis B vaccine coverage for infection control. By acting as a 'care coordinator of hepatitis', the dentist will be able to contribute to the eradication of liver cancer in Japan, thereby eliminating the discrimination and prejudice against patients with hepatitis. Dentists need to have a deep understanding of liver disease from the viewpoints of both nosocomial infection control and treatment of oral diseases.

Abstract
Periodontal disease has been associated with liver disease; however, the identities of the periodontal disease-causing bacteria in patients with viral liver disease remain unknown. The aim of the present study was to determine the counts of the 3 periodontal pathogens that form the red complex in chronic periodontitis (Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola) and 3 other bacteria (Aggregatibacter actinomycetemcomitans, Prevotella intermedia and Fusobacterium necrophorum) in patients with liver disease. A total of 47 patients with liver disease were divided into two groups based on the counts of the red complex bacteria: group A (high counts of red complex bacteria) and group B (low counts of red complex bacteria). The counts of the 6 types of bacteria in saliva and the prevalence of P. gingivalis-specific fimA genotype were determined. In addition, salivary occult blood tests and serological assays were performed. Univariate and multivariate logistic regression analyses were used to analyze the risk factors between the two groups of patients. Hepatitis C virus-related liver disease was the most frequent (41/47; 87.2%) occurrence followed by liver cirrhosis (LC; 12/47; 25.5%) and oral lichen planus (32/47; 68.1%). The significant risk factors between the two groups were LC, albumin (Alb) level, ratios of each bacteria and prevalence of the fimA II genotype. The 3 factors identified in the multivariate analysis to be associated with the red complex bacteria count were low Alb level (<3.7 g/dl), LC and fimA II genotype, with adjusted odds ratios of 6.93, 4.72 and 4.08, respectively (P<0.05). These data indicated that patients with LC were at increased risk of presenting with the red complex bacteria leading to periodontal disease progression. Therefore, these patients may need to take additional care of their oral health compared with patients without LC, which may prove beneficial for the maintenance of their general health.

Abstract
BACKGROUND Although the prevalence of extrahepatic manifestations of chronic hepatitis C virus (HCV) infection has been reported from Western countries, their prevalence in East Asian countries is not well known. AIM To perform a systematic review to quantify the prevalence of selected extrahepatic manifestations of HCV among patients from East Asia. METHODS Medline, CINAHL, EMBASE, Cochrane and country-specific databases were reviewed according to standard guidelines for meta-analyses. Only articles with patients from East Asian countries were included. RESULTS After review, 34 articles were selected (Japan = 9; China = 5, Korea = 3, Taiwan = 16, multiple countries = 1) with 646 228 subjects, 66 436 with HCV. Mean age for HCV-infected patients was 56 years (range 41-72 years), 50% were male (range 26%-73%). The pooled prevalence of type 2 diabetes in East Asian HCV patients was 19.0% (95% confidence interval 15.6%-22.9%) (n = 19 studies) with an increased risk when compared to non-HCV: odds ratio (OR) 1.58 (1.28-1.94). The prevalence of chronic kidney disease in HCV was 9.2% (5.0%-16.2%) (n = 7 studies), also with a significantly increased risk: OR=1.98 (1.41-2.77). Pooled prevalence of cardiovascular disease in HCV was 8.6% (3.5%-19.9%) (n = 6 studies), also with an increased risk: OR = 1.55 (1.21-1.98). The prevalence of lichen planus in HCV was 8.9% (3.6%-20.6%) (n = 6 studies) while the prevalence of rheumatoid arthritis was 4.5% (0.6%-25.7%) (n = 4 studies). CONCLUSIONS These data show increased risk of developing extrahepatic manifestations in East Asian patients with HCV. Both hepatic and extrahepatic manifestations of the infection should be used to accurately determine the total burden of the disease in the region.

Abstract
Objective The association between Sjögren’s syndrome (SS) and chronic hepatitis virus infection is inconclusive. Hepatitis B (HBV) and hepatitis C virus (HCV) infections are highly prevalent in Taiwan. We used a population-based case-control study to evaluate the associations between SS and HBV and HCV infections. Materials and Methods We identified 9,629 SS patients without other concomitant autoimmune diseases and 38,516 sex- and age-matched controls without SS from the Taiwan National Health Insurance claims data between 2000 and 2011. We utilized multivariate logistic regression to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) of the associations between SS and HBV and HCV infections. Sex- and age-specific (<55 and ≥55 years) risks of SS were evaluated. Results The risk of SS was higher in patients with HCV than in those without chronic viral hepatitis (OR = 2.49, 95% CI = 2.16–2.86). Conversely, HBV infection was not associated with SS (OR = 1.10, 95% CI = 0.98–1.24). Younger HCV patients were at a higher risk for SS (<55 years: OR = 3.37, 95% CI = 2.62–4.35; ≥55 years: OR = 2.20, 95% CI = 1.84–2.62). Men with HCV were at a greater risk for SS (women: OR = 2.26, 95% CI = 1.94–2.63; men: OR = 4.22, 95% CI = 2.90–6.16). Only men with chronic HBV exhibited a higher risk of SS (OR = 1.61, 95% CI = 1.21–2.14). Conclusion HCV infection was associated with SS; however, HBV only associated with SS in men.

Abstract
PURPOSE To investigate the independent risk factors of dry eye syndrome (DES) in Chinese. METHODS A hospital-based age- and sex-matched population was enrolled with a case-control ratio of 1:2, with 789 DES case patients and 1119 healthy family members. Both groups underwent standard ophthalmologic examinations, including slit-lamp evaluation of the anterior segment, measurement of tear film breakup time, Schirmer test, and corneal fluorescein staining. Data on demographic characteristics and lifestyle habits were collected using a questionnaire. Dry eye syndrome risk factors were identified by univariate and multivariate logistic regression analyses. RESULTS The following independent risk factors showed significant association with DES: diabetes (odds ratio [OR], 1.408; 95% confidence interval [CI], 1.031 to 1.924), hepatitis C (OR, 3.326; 95% CI, 1.632 to 6.776); connective tissue disease (OR, 2.157; 95% CI, 1.679 to 2.771), benign prostatic hyperplasia (OR, 3.892; 95% CI, 2.476 to 6.116), rosacea (OR, 3.747; 95% CI, 1.972 to 7.120), posttraumatic stress disorder (OR, 1.449; 95% CI, 1.043 to 2.013), hematopoietic stem cell transplantation (OR, 7.269; 95% CI, 2.312 to 22.849), head and neck radiotherapy (OR, 8.776; 95% CI, 3.096 to 24.873), postmenopausal estrogen therapy (OR, 1.912; 95% CI, 1.160 to 3.151), antihistamines (OR, 2.040; 95% CI, 1.516 to 2.746), antidepressants (OR, 1.982; 95% CI, 1.077 to 3.647), contact lenses (OR, 2.366; 95% CI, 1.266 to 4.423), and video display terminal exposure for more than 6 h/d (OR, 2.275; 95% CI, 1.451 to 3.568). Potentially protective factors against DES were vitamin supplements (OR, 0.716; 95% CI, 0.528 to 0.972) and Ω-3 fatty acid-rich diet (OR, 0.514; 95% CI, 0.332 to 0.796). CONCLUSION Several known risk factors of DES are applicable to Chinese, and some distinctive dietary factors may be protective in this population.

Abstract
Previous studies have suggested an association between hepatitis C virus (HCV) infection and the development of Sjögren's syndrome (SS), also known as sicca syndrome. The main objective of this study was to summarize the existing evidence and quantitatively evaluate the association between hepatitis C virus infection and SS/sicca syndrome by performing a meta-analysis of observational studies. MEDLINE and PubMed (January 1980-August 2013) were searched to identify relevant studies in English. Outcomes were calculated and are reported as odds risk (OR) and 95% CIs based on a random-effects model. Heterogeneity was assessed with I(2) statistics. Quality assessment was performed with the Newcastle-Ottawa scale. Based on meta-analysis of five cross-sectional and five cohort studies, a significant positive relationship between HCV infection and development of SS/sicca syndrome was found, the pooled random effects OR being 3.31 (95% CI, 1.46-7.48; P < 0.001). In subset analyses, the studies that used European diagnostic criteria showed a higher summary OR than did studies that adopted other diagnostic criteria. When the data were stratified by source of controls, significant associations were also observed when healthy people (OR = 9.44; 95% CI = 2.67-33.40; P = 0.204) or subjects with hepatitis B virus infection (OR = 6.57; 95% CI = 1.21-35.57; P = 0.5) were used as controls, but not when the controls were hospital-based (OR = 0.99; 95% CI = 0.61-1.61; P = 0.169). In summary, the findings suggest that HCV infection is associated with SS/sicca syndrome. The observed increased risk in studies in which European diagnostic criteria and healthy controls were used and the decreased risk in studies with hospital-based controls may be attributable to selection bias or other unknown factors.

Abstract
The association of chronic hepatitis C with immune related syndromes has been frequently reported. There is a great range of clinical manifestations affecting various systems and organs such as the skin, the kidneys, the central and peripheral nervous system, the musculoskeletal system and the endocrine glands. Despite the high prevalence of immune related syndromes in patients with chronic hepatitis C, the exact pathogenesis is not always clear. They have been often associated with mixed cryoglobulinemia, a common finding in chronic hepatitis C, cross reaction with viral antigens, or the direct effect of virus on the affected tissues. The aim of this review is to analyze the reported hepatitis C virus immune mediated syndromes, their prevalence and clinical manifestations and to discuss the most supported theories regarding their pathogenesis.

Abstract
Saliva plays a key role in maintaining oral homeostasis, function, and health. The prevalence of xerostomia and its consequences are rising due to the increasing aging population, the effects of some systemic diseases, medical management, and commonly-prescribed medications that reduce saliva production. When salivary function is diminished, patients are at a greater risk of developing caries, discomfort in wearing dentures, and opportunistic diseases, such as candidiasis. The psychosocial aspects of xerostomia can range from a mild effect on self-rated oral health to frustration, embarrassment, unhappiness, or substantial disruptions in quality of life. This article reviews the clinical features, diagnosis, and prevalence of dry mouth, as well as its treatment strategies.

Abstract
PURPOSE OF REVIEW To summarize the recent developments concerning the potential viral pathomechanisms and involvement of viruses in Sjögren's syndrome, and to highlight the areas for future research and therapies. RECENT FINDINGS Activated IFN-1 pathway plays an important part in the autoimmune disease process of Sjögren's syndrome; therefore, several therapies aiming to reduce or inhibit the IFN-1 production and its effects may be a target for future treatment plans. Activated aryl hydrocarbon receptor may interact with latent Epstein-Barr virus (EBV) infection, which in turn may predispose to the development of Sjögren's syndrome. It is estimated that the population is 95% positive for EBV serology. Microbial factors may incite autoimmune disease. Although this hypothesis is proven in a few illnesses such as rheumatic fever, there is no definitive evidence of an infectious environmental trigger in Sjögren's syndrome. However, there are circumstantial data with regard to viruses and several potential mechanisms of disease. These include antigen mimicry, polyclonal lymphocyte activation, and infection-mediated innate end-organ inflammation. In addition, hepatitis C virus infection clearly causes a Sjögren's-syndrome-like illness. SUMMARY Data continue to implicate viral infection in the cause of Sjögren's syndrome, but there are no definitive studies incriminating a particular virus.

Abstract
Background Oral lichen planus (OLP) is seen frequently in patients with hepatitis C virus (HCV) infection. The aim of this study was to evaluate the occurrence of oral candidiasis, other mucosal lesions, and xerostomia during interferon (IFN) therapy for HCV infection. Methods Of 124 patients with HCV-infected liver diseases treated with IFN therapy in our hospital, 14 (mean age 56.00 ± 12.94 years) who attended to receive administration of IFN once a week were identified and examined for Candida infection and other oral lesions and for the measurement of salivary flow. Serological assays also were carried out. Results Cultures of Candida from the tongue surfaces were positive in 7 (50.0%) of the 14 patients with HCV infection at least once during IFN therapy. C. albicans was the most common species isolated. The incidence of Candida during treatment with IFN did not increase above that before treatment. Additional oral mucosal lesions were observed in 50.0% (7/14) of patients: OLP in three (21.4%), angular cheilitis in three (21.4%) and recurrent aphthous stomatitis in one (7.1%). OLP occurred in one patient before treatment with IFN, in one during treatment and in one at the end of treatment. 85.7% of the oral lesions were treated with topical steroids. We compared the characteristics of the 7 patients in whom Candida was detected at least once during IFN therapy (group 1) and the 7 patients in whom Candida was not detected during IFN therapy (group 2). The prevalence of oral mucosal lesions (P=0.0075) and incidence of external use of steroids (P=0.0308) in group 1 were significantly higher than in group 2. The average body weight of group 1 decreased significantly compared to group 2 (P=0.0088). Salivary flow decreased in all subjects throughout the course of IFN treatment and returned at 6th months after the end of treatment. In group 1, the level of albumin at the beginning of the 6th month of IFN administration was lower than in group 2 (P=0.0550). According to multivariate analysis, one factor, the presence of oral mucosal lesions, was associated with the detection of Candida. The adjusted odds ratio for the factor was 36.00 (95% confidence interval 2.68-1485.94). Conclusion We should pay more attention to oral candidiasis as well as other oral mucosal lesions, in patients with weight loss during IFN treatment.

Abstract
This article reviews current understanding of the clinical manifestations, diagnosis and treatment of Sjögren's syndrome. Sjögren's syndrome is a chronic inflammatory disorder of the exocrine glands with multiple nonexocrine features. It is found predominantly in middle-aged women but exists throughout the population. The diagnosis of Sjögren's syndrome can be challenging because the cardinal sicca symptoms may be subclinical or attributed to other causes, such as medications or aging. Differential diagnosis of Sjögren's syndrome can be confounded by the multiple exocrine manifestations in the mouth, eyes, ears, nose, skin, vagina, and respiratory and gastrointestinal tracts, as well as seemingly unrelated nonexocrine involvement in the thyroid, liver, kidneys and the musculoskeletal, vascular and nervous systems. This article concludes that early diagnosis of Sjögren's syndrome is crucial to prevent and/or minimize potentially life-threatening complications. Periodic follow-up of patients' status and collaboration between the primary-care physician and the rheumatologist, dentist, ophthalmologist and other specialists are indispensable.

Abstract
Patients with chronic hepatitis C virus (HCV) infection frequently have many extrahepatic manifestations, as persistent HCV infection often triggers lymphoproliferative disorders and metabolic abnormalities. These manifestations primarily include autoimmune disorders such as cryoglobulinemia, Sjögren's syndrome, and autoimmune thyroid disorders. It has been well established that chronic HCV infection plays important roles in the production of non-organ-specific autoantibodies, including antinuclear antibodies and smooth muscle antibodies, and organ-specific autoantibodies such as thyroid autoantibodies. However, the clinical significance of autoantibodies associated with the extrahepatic manifestations caused by HCV infection has not been fully recognized. In this paper, we mainly focus on the relationship between extrahepatic manifestations and the emergence of autoantibodies in patients with HCV infection and discuss the clinical relevance of the autoantibodies in the extrahepatic disorders.

Abstract
BACKGROUND Oral lichen planus (OLP) decreases the quality of life because it can cause spontaneous pain during eating and tooth-brushing and an uncomfortable feeling in the mouth. In addition, OLP may be associated with HCV-related liver disease.We investigated the visual analogue scale (VAS) and effects of oral care gel, REFRECARE-H®, on patients with OLP associated with HCV infection. RESULTS Nine OLP patients (mean age 67.9 ± 7.6 years) with HCV-related liver diseases were recruited and their VAS score determined along with a biochemical examination of the blood. Types of OLP included erosive (6 patients) and reticular (3). REFRECARE-H®, an oral care gel (therapeutic dentifrice) containing hinokitiol, was applied by each patient as a thin layer on the oral membrane, after each meal and at bedtime for 30 days. Application of REFRECARE-H® improved the quality of life in all terms of dry mouth, breath odor, oral freshness, oral pain during rest, oral pain at a mealtimes, taste disorder, loss of appetite, sleep disorder, depressive mood and jitteriness. VAS scores of dry mouth, breath odor, oral freshness, and sleep disorder were significantly increased 30 days after application of REFRECARE-H® (P = 0.01, P = 0.05, P = 0.03, P = 0.04). VAS scores of oral pain at a mealtimes and taste disorder were increased 30 days after application of REFRECARE-H® (P = 0.06). There was an absence of side effects. CONCLUSIONS REFRECARE-H® improved the quality of life for OLP. It is necessary for the hepatologist to educate patients regarding oral hygiene, as well as provide treatment of liver disease.

Abstract
BACKGROUND There has been little discussion about the importance of oral management and interferon (IFN) therapy, although management of the side effects of therapy for chronic hepatitis C has been documented. This study determined whether dental problems delayed the initiation of IFN therapy for hepatitis C virus (HCV)-infected patients. RESULTS We analyzed 570 HCV-infected patients who were admitted to our hospital from December 2003 to June 2010 for treatment consisting of pegylated IFN (Peg-IFN) monotherapy or Peg-IFN/ribavirin combination therapy. The group comprised 274 men and 296 women with a mean age 57.2 years. Of the 570 patients, six could not commence Peg-IFN therapy, despite their admission, because of dental problems such as periodontitis, pupitis, and pericoronitis. The ages of six whose dental problems delayed the initiation of Peg-IFN ranged from 25 to 67 years, with a mean age of 47.3 +/- 15.2 years. IFN therapy was deferred for 61.3 +/- 47.7 days. Among the six subjects for whom IFN treatment was delayed, only one had a salivary flow that was lower than the normal value. CONCLUSIONS Treatment of dental infections is required before IFN therapy for HCV infection can be started. To increase the depth of understanding of oral health care, it is hoped that dentists and medical specialists in all areas will hold discussions to generate cooperation.

Abstract
OBJECTIVE Although multiple diseases associated with primary Sjögren's syndrome (pSS) have been reported, reliable data regarding the prevalence of specific medical comorbidities among patients with pSS remain sparse. We investigated the prevalence and risk for a broad spectrum of medical conditions among patients with pSS in Taiwan. METHODS A total of 1974 patients with pSS were eligible for inclusion in the study group. We randomly selected 9870 enrollees matched with the study subjects, using the Taiwan National Health Insurance Research Dataset for 2006 and 2007, inclusive. Conditional logistic regression analyses conditioned on sex, age, monthly income, and level of urbanization of the patient's community were used to calculate the odds ratios (OR) of various comorbid conditions. RESULTS Pearson chi-square tests revealed that patients with pSS had significantly higher prevalence of hyperlipidemia, cardiac arrhythmias, headaches, migraines, fibromyalgia (FM), asthma, pulmonary circulation disorders, hypothyroidism, liver disease, peptic ulcers, hepatitis B, deficiency anemias, depression, and psychoses. Conditional regression analyses showed that, compared to patients without the condition, patients with pSS were more likely to have hyperlipidemia (OR 1.42), cardiac arrhythmias (OR 1.32), headaches (OR 1.47), migraines (OR 1.86), FM (OR 1.71), asthma (OR 1.54), pulmonary circulation disorders (OR 1.42), hypothyroidism (OR 2.37), liver disease (OR 1.89), peptic ulcers (OR 1.88), hepatitis B (OR 2.34), deficiency anemias (OR 1.33), depression (OR 2.57), and psychoses (OR 2.15). CONCLUSION The prevalence of several comorbidities was increased among the patients with pSS. Our study provides epidemiological data for comorbidities among pSS patients in an ethnic Chinese population.

Abstract
OBJECTIVE Hepatitis C virus infection (HCV) is associated with various extrahepatic manifestations. Antibodies against alpha-fodrin are associated with sicca symptoms and may valuable diagnostic markers in patients with primary Sjögren syndrome (SS) lacking Ro antibodies. The frequency and role of alpha-fodrin antibodies in patients with chronic HCV infection are unknown. The aim of this study was to investigate the prevalence of alpha-fodrin antibodies in HCV-infected patients with SS. MATERIAL AND METHODS Alpha-fodrin antibodies were detected more often in hepatitis C patients (25%; n=142) than in HBV-infected individuals (8%; n=49) and healthy controls (6%; n=174) (p<0.01). Based on these findings, we investigated the frequency of sicca symptoms in a second cohort and studied other antibodies associated with SS. RESULTS HCV-infected individuals showed sicca symptoms in 53% of cases as determined by the Saxon and Schirmer tests, which was more frequent than in healthy controls (1%, p<0.01) but not in patients with autoimmune liver disease (51%). Antibodies specific for Ro (SS-A) were significantly more common in patients with autoimmune liver disease than in HCV-infected patients and healthy controls (16% versus 1% and 0%, p<0.003). SS was found in 18% of patients with HCV, in 15% of patients with autoimmune liver disease and in 1% of healthy controls. However, we found no correlation between sicca symptoms and the presence of antibodies against alpha-fodrin, Ro and La. CONCLUSIONS Patients with chronic HCV infection show a high prevalence of sicca symptoms and antibodies against alpha-fodrin. However, neither the frequency nor the severity of symptoms correlated with the presence of alpha-fodrin antibodies.

Abstract
OBJECTIVE Our purpose was to carry out an epidemiological study to assess the prevalence of oral mucosal conditions in Brazilian patients with chronic hepatitis C. METHODS A cross-sectional survey was carried out on 215 patients with chronic hepatitis C who were examined for oral mucosal conditions, including oral mucosal lesions and variations of normality. RESULTS The prevalence of patients with chronic hepatitis C presenting oral mucosal conditions was 96.3 percent (207 patients). Oral mucosal lesions were present in 147 patients (68.4 percent), whereas variations of normality were observed in 173 patients (80.5 percent). The most common lesions included cheek biting in 42 cases (19.5 percent), candidiasis in 39 cases (18.1 percent), and leukoplakia in 28 cases (13.0 percent). The association of oral lichen planus with hepatitis C virus (HCV) infection proved to be statistically significant (P = 0.002). The most frequent variations of normality included Fordyce's spots in 96 cases (44.7 percent), lingual varicosities in 67 cases (31.2 percent), and fissured tongue in 60 cases (27.9 percent). CONCLUSION The prevalence of patients with chronic hepatitis C presenting oral mucosal conditions was 96.3 percent. Despite this high prevalence, only the association between oral lichen planus and hepatitis C showed statistical significance. Considering that HCV infection may be associated with extrahepatic disorders, such as oral manifestations, efforts should be made to clarify the possible relation between oral conditions and HCV infection. This may be helpful in the earlier diagnosis of the infection mainly in asymptomatic patients.

Abstract
The etiology and pathogenesis of autoimmune diseases have long been an enigmatic subject that have involved genetic and environmental factors. Recent intriguing data has contributed to the mechanisms involved, including the relationship of infectious agents and loss of tolerance. This loss of tolerance is illustrated by the data on the immune response to Hepatitis B virus such as the molecular mimicry between HBV antigens and self proteins, the generation of immune complexes between HBV antigens and antibodies, and apoptosis/tissue damage resulting in the exposure of intracellular antigens to the immune system. In this paper, we review the current database related to HBV infection and a variety of autoimmune conditions, including autoimmune hepatitis, systemic lupus erythematosus, aplastic anemia, antiphospholipid syndrome, polyarteritis nodosa, rheumatoid arthritis, type 1 diabetes, multiple sclerosis, thyroid disease and uveitis.

Abstract
Hepatitis C virus (HCV) infection is frequently associated with anti-SSA/Ro and anti-SSB/La autoantibodies. The objective of this study is to examine the prevalence of anti-SSA/Ro and anti-SSB/La autoantibodies in HCV-infected patients and their possible associations with HLA-DRB1 polymorphism in Chinese patients in Taiwan. About 288 HCV-infected patients were recruited for autoantibody detection and HLA-DRB1 typing. Anti-SSA/Ro and anti-SSB/La autoantibodies were detected in 12.8 and 9.7% of HCV-infected patients. Anti-SSA/Ro antibody was positively associated with age over 55 [p = 0.04; odds ratio = 2.17; 95% confidence interval (CI), 1.03-4.57]. Anti-SSB/La antibody was negatively associated with HLA-DR2 carriage (p = 0.024; odds ratio = 0.30; 95% CI, 0.10-0.90). No significant correlation was found between autoantibody production and gender, autoimmune manifestation, presence of cirrhosis, or hepatocellular carcinoma in HCV infection. In conclusion, anti-SSA/Ro and anti-SSB/La antibodies present frequently in HCV-infected patients. Anti-SSB/La antibody is negatively associated with HLA-DR2 in HCV-infected patients in Taiwan.

Abstract
Morbidity associated with hepatitis C virus (HCV) infection is due not only to the sequelae of chronic liver disease, but also to a variety of extraheaptic manifestations (EHM). Some of the most frequently reported EHM of HCV infection involves the oral region predominantly or exclusively and they are the topics of this 2-part review. The current part 1 discusses the evidences on the association of salivary glands disorders with HCV. HCV- infected patients may frequently have histological signs of Sjögren-like sialadenitis with mild or even absent clinical symptoms. However, the pathogenetic role of HCV in Sjogren Syndrome (SS) development and the characteristics distinguishing classic SS from HCV-related sialadenitis are still an issue. It is unclear if the virus may cause a disease mimicking primary SS or if HCV is directly responsible for the development of SS in a specific subset of patients. Notably, some patients may present a triple association between HCV, SS-like sialadenitis and salivary gland lymphoma and the virus may be involved in the lymphomagenesis. The risk of having a salivary gland lymphoma is particularly high in patients with mixed cryoglobulinemia. Little attention has been paid to the effects of anti-HCV treatment on sialadenitis or lymphoma development.

Abstract
Living kidney donation is increasing because of prolonged waiting times on the transplant list, as well as improved outcomes for recipients. In 2001, the number of living donors surpassed the number of deceased donors; this trend likely will continue with ever-increasing margins. Because of this increase, as well as changes in our society's health, it is time to re-review the guidelines for selecting living kidney donors established by Kasiske et al in 1995. A conference will be held this year to review updated literature on medical conditions that impact on renal health. From this, new guidelines for the medical evaluation of living renal donors will be constructed. This review discusses information known to date on the outcomes of individuals undergoing unilateral nephrectomy, the impact of lifestyle on renal function in the setting of nephrectomy, and advancements in the detection of genetically transmitted renal diseases that impact on today's decisions on living donation.
