Abstract
INTRODUCTION The symptom of dry mouth has multiple potential etiologies and can be a diagnostic clue to the presence of common systemic diseases encountered in rheumatology practice. The presence of decreased saliva flow (i.e. salivary hypofunction) defines a subset of dry mouth patients in whom there may be reversible drug effects, an iatrogenic insult such as head and neck irradiation, or a disease that directly involves the salivary glands (e.g. Sjögren's disease). The assessment of salivary hypofunction includes sialometry, salivary gland imaging, salivary gland biopsy, and an assessment for relevant systemic diseases. Optimal management of dry mouth requires accurate definition of its cause, followed by general measures that serve to alleviate its symptoms and prevent its complications. AREAS COVERED Through a literature search on xerostomia and salivary hypofunction, we provide an overview of the causes of dry mouth, highlight the potential impact of salivary hypofunction on oral and systemic health, detail routine evaluation methods and treatment strategies, and emphasize the importance of collaboration with oral health care providers. EXPERT OPINION Our Expert Opinion is provided on unmet needs in the management of dry mouth and relevant research progress in the field.

Abstract
Sjögren’s syndrome (SS) is an autoimmune disease especially targeting exocrine glands, such as the salivary and lacrimal glands. A radical therapy for SS based on its etiology has not been established because of the complex pathogenesis of the disease. Several studies have demonstrated a relationship between virus infection and SS pathogenesis. In particular, infection with the Epstein-Barr (EB) virus among others is a potent factor associated with the onset or development of SS. Specifically, virus infection in the target organs of SS triggers or promotes autoreactive responses involving the process of autoantigen formation, antigen-presenting function, or T-cell response. Our review of recent research highlights the crucial roles of virus infection in the pathogenesis of SS and discusses the critical association between virus infection and the etiology of autoimmunity in SS.

Abstract
Hepatitis C virus (HCV) infection is the most common blood-borne chronic infection in the United States. Chronic lymphocytic sialadenitis and sicca syndrome have been reported in chronic HCV infection. Up to 55% of these patients may have xerostomia; the mechanisms of the xerostomia and salivary gland (SG) hypofunction remain controversial. The objectives of this project are to establish if xerostomia associates with SG and HCV infection and to characterize the structural changes in SG and saliva composition. Eighteen HCV-infected patients with xerostomia were evaluated for SG dysfunction; 6 of these patients (patients 1–6) were further evaluated for SG histopathological changes and changes in saliva composition. The techniques used include clinical and laboratory assessment, SG ultrasonography, histological evaluation, sialochemical and proteomics analysis, and RNA in situ hybridization. All the HCV patients had low saliva flow, chronic sialadenitis, and SG fibrosis and lacked Sjögren syndrome (SS) characteristic autoantibodies. Further evaluation of a subgroup of 6 HCV patients (patients 1–6) demonstrated diffuse lymphocytic infiltrates that are predominantly CD8+ T cells with a significant increase in the number of inflammatory cells. Alcian Blue/periodic acid–Schiff staining showed significant changes in the ratio and intensity of the acinar secretory units of the HCV patients’ minor SG. The submandibular glands showed significant ultrasonographic abnormalities in the parenchyma relative to the parotid glands. Significant changes were also observed in the concentration of sodium and mucin 5b. Although no significant correlation was observed between the lymphocytic infiltrates and the years of HCV chronic infection, a positive correlation was observed between HCV RNA–positive epithelial cells and the years of HCV infection. Consistent with the low saliva flow and xerostomia, patients showed changes in several markers of SG acinar and ductal function. Changes in the composition of the saliva suggest that HCV infection can cause xerostomia by mechanisms distinct from SS.

Abstract
Background Oral lichen planus (OLP) and hyposalivation have been reported as extrahepatic manifestations of hepatitis C virus (HCV) infection. Our study evaluated the effect of direct antiviral agents (DAAs) on OLP and hyposalivation in convicts with chronic hepatitis C, examining patients before, during and after the antiviral treatment period with direct acting antiviral agents (DAAs). Methods We screened 198 inmates for the presence of the HCV antibody. Patients found to be positive underwent a quantitative HCV-RNA test and HCV genotype typing, as well as an oral cavity examination using a scoring system for OLP (REU score) and the clinical oral dryness score (CODS). Subsequently, all patients underwent DAA therapy and a systematic physical examination of the oral cavity at 1, 3 and 6 months from the beginning of treatment. Results Fifty patients (25.25%) had a positive HCV-RNA test. At baseline, OLP was detected in 4 patients (8%), with a mean REU score of 10.13±4, and different degrees of hyposalivation were seen in 17 patients (34%), with a mean CODS score of 4.71±1.72. Six months after the start of DAA therapy, we observed resolution of OLP in 3 patients (75%) and improvement in the remaining subject with a significantly lower mean REU score (2±4). Hyposalivation disappeared in 5 patients, improved in 10, and remained unchanged in 2 patients with a significantly lower mean CODS score (0.06±0.24). Conclusion This study demonstrated the effectiveness of DAAs in the treatment of OLP and hyposalivation.

Abstract
We developed an electrolyte pre-deposition-based saliva pattern modulation method to detect ovulation with high accuracy and reliability. Ovulation tests using human saliva have advantages in terms of the earlier ovulation detection and more convenient sample collection procedure; however, accuracy is low, which is a critical limitation given that the concentrations of salivary constituents can vary depending on the health status of the tested individual and subjective user judgement of the test result. In this study, we quantitatively analyzed saliva patterns according to the concentrations of electrolytes and proteins in the ovulation test and found that changes in the saliva pattern during the ovulatory period can be controlled by sodium chloride (NaCl) pre-deposition, which directly affects the accuracy of ovulation detection. The 100 nmol NaCl pre-deposition condition proved optimal, being two-fold more sensitive to changes in saliva pattern versus the non-pre-deposition condition (accuracy of ovulation detection = 66.6% and 33.3%, respectively). Although accuracy remained insufficient for actual applications compared to the urine-based ovulation detection method, we expect that the electrolyte pre-deposition method will greatly contribute to enhancing the performance of saliva-based ovulation detection tests, toward a commercially satisfactory level of accuracy.

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
Hepatitis C virus can be detected in blood and other bodily fluids, such as saliva. The aim of this study was to detect and quantify the HCV-RNA in saliva and plasma from patients with chronic hepatitis C infections, as well as check the level of viral load in sex groups (age, ethnicity and virus subtypes). Whole saliva and blood from 70 patients with chronic hepatitis C infections attended at the department of gastroenterology from University Hospital. The HCV-RNA load was performed by qRT-PCR using Sybr Green I master mix. HCV-RNA was detected in 80% (56/70) of patients in saliva and 92.85% (65/70) in plasma. The median of the viral load in the plasma was of 4.87 log10, and in saliva, it was 3.32log10, (p = 0.0005). Female patients and black patients exhibited a negative correlation between the HCV-RNA load in saliva vs. the HCV-RNA load in plasma (r = -0.3172, CI95% -0.6240 to -0.03736, p = 0.0491) and (r = -0.3141; IC95% -0.6069 to -0.05926; p = 0.0209), respectively. HCV-RNA was detected and quantified in saliva samples, and according to the quantification levels, saliva may be a possible transmission source of HCV, particularly in women and people of black ethnicity who develop chronic HCV infections.

Abstract
INTRODUCTION Hepatitis C virus (HCV) infections are associated with extrahepatic manifestations in 40-75 % of cases. Sialitis and secondary Sjögren syndrome are well characterized complications of chronic HCV infections but the mechanisms (primary or secondary) leading to xerostomia are not understood. Similarly, brain lesions due to HCV can be primary or secondary but the pathology of primary HCV-related brain lesions is not well described. CASE REPORT We report the postmortem case of a 60-year old patient initially presenting with sicca syndrome and dementia. HCV was identified in the brain but not in the salivary glands using transcription-mediated amplification (TMA). Focal sialitis was found in submandibular glands. Neuropathological examination revealed the presence of multiple dot-sized demyelination foci. CONCLUSION Sicca syndrome is a common concern in chronic HCV infections and may be due to secondary immune mechanisms (we could not isolate HCV in salivary gland tissues). TMA had never been applied to the detection of viruses in salivary glands and neural tissues and proves to be a promising technique. Neuropathological reports in HCV infections are rare and the lesions we report may be the first characterization of the direct effect of HCV on brain cells. More cases are needed to define the full spectrum of lesions potentially caused by the direct action of the HCV on salivary glands and neural tissues.

Abstract
Sjogren syndrome (SS) is an autoimmune disease that affects exocrine glands and therefore may affect the gastrointestinal system, from the mouth, esophagus, and bowel to the liver and pancreas. Oral involvement in SS is mainly characterized by dryness, with a wide spectrum of symptoms, from mild-to-severe xerostomia with dysgeusia and tooth decay. The dysphagia, although common, does not correlate with the reduced salivary flow rate or the dysmotility that may be present. Dyspepsia, found in up to 23% of patients, may be associated with gastritis, reduced acid production, and antiparietal cell antibodies, but rarely pernicious anemia. Pancreatic involvement, although rare, includes pancreatitis and pancreatic insufficiency. The most common causes of liver disease are primary biliary cirrhosis, autoimmune hepatitis, nonalcoholic fatty liver disease, and hepatitis C virus (HCV). Although abnormal liver tests are found in up to 49% of patients, they are usually mild. Although sicca syndrome, abnormal histology of the salivary glands, and abnormal sialograms are common in primary biliary cirrhosis, the antibodies to Ro/SSA or La/SSB antigens are infrequent. Xerostomia, sialadenitis, abnormal salivary flow rates, and abnormal Schirmer test in HCV vary widely among the studies, although the antibodies to Ro/SSA or La/SSB are only 1%. Several studies show that HCV is in saliva, although how this may impact sicca syndrome or SS in HCV is unclear. SS as a disease of exocrine glands affects many parts of the gastrointestinal system.

Abstract
BACKGROUND AND AIMS Viral hepatitis is a significant global health problem that, depending upon the virus, affects individuals of the developing and/or developed world. In recent years, there has been renewed interest in whether oral fluids can be considered as a source of viral hepatitis transmission and whether oral fluid, in particular, whole saliva, may be a useful source for viral detection as part of the diagnosis and monitoring of viral hepatitis. The aim of this article was to review current data concerning the possible carriage of the hepatitis A, B and C viruses within saliva and gingival crevicular fluid. Such knowledge will indicate if (i) oral fluid is a possible source of infection and (ii) whether oral fluid can be used for diagnosis and monitoring of viral hepatitis. DATA AND SOURCES A literature search was conducted using PubMed (Medline), EMBASE/Excerpta medica, the Cochrane database and Scopus. The results were limited to published material after 2000. Relevant material was evaluated and reviewed. CONCLUSION There is some evidence that hepatitis viruses A, B and C are present in oral fluids, particularly whole saliva and gingival crevicular fluid and may thus be possible sources of viral detection in clinical diagnosis and monitoring. However, the data are inconsistent and warrant the need for well-planned longitudinal studies to explore the precise frequency of oral carriage of such viruses and to determine the virological and host factors that may influence the oral presence of hepatitis A, B and C viruses.

Abstract
Oral candidosis is the most common fungal infection encountered in general dental practice. It manifests in a variety of clinical presentations which may mimic more sinister diseases, and can occasionally be refractory to treatment requiring the attention of an oral medicine specialist. Management of oral candidosis should always include a thorough investigation of underlying predisposing conditions, as the disease often presents when the patient is systemically compromised. This update highlights the pathogenesis, clinical presentation, and management strategies of oral Candidal lesions commonly encountered in dental practice.

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.

Salivary dysfunction associated with systemic diseases: systematic review and clinical management recommendations. ACTA ACUST UNITED AC 2007; 103 Suppl:S57.e1-15. [PMID: 17379156 DOI: 10.1016/j.tripleo.2006.11.010] [Citation(s) in RCA: 93] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2006] [Accepted: 11/08/2006] [Indexed: 01/29/2023]
Abstract
OBJECTIVES The objective of this study was to identify systemic diseases associated with hyposalivation and xerostomia and develop evidence-based management recommendations for hyposalivation/xerostomia. STUDY DESIGN Literature searches covered the English language medical literature from 1966 to 2005. An evidence-based review process was applied to management studies published from 2002 to 2005. RESULTS Several systemic diseases were identified. From studies published 2002 to 2005, 15 were identified as high-quality studies and were used to support management recommendations: pilocarpine and cevimeline are recommended for treating hyposalivation and xerostomia in primary and secondary Sjögren's syndrome (SS). IFN-alpha lozenges may enhance saliva flow in primary SS patients. Anti-TNF-alpha agents, such as infliximab or etanercept, are not recommended to treat hyposalivation in SS. Dehydroepiandrosterone is not recommended to relieve hyposalivation or xerostomia in primary SS. There was not enough evidence to support any recommendations for the use of local stimulants, lubricants, and protectants for hyposalivation/xerostomia. However, professional judgment and patient preferences may support the use of a specific product for an individual patient. CONCLUSIONS These evidence-based management recommendations should guide the clinician's management decisions for patients with salivary dysfunction related to systemic disease. Future treatment strategies may include new formulations of existing drugs, e.g., local application of pilocarpine. Recent discoveries on gene expression and a better understanding of the etiopathogenesis of SS may open new treatment options in the future.

Abstract
BACKGROUND A review of the literature reveals controversy regarding the relationship between hepatitis C virus (HCV) infection and oral leukoplakia (OL). The aim of this study was to determine the frequency of HCV antibodies in patients with OL and control subjects resident in Serbia. METHODS In this cross-sectional study 73 consecutive patients with histologically proven OL and 90 control subjects, whose age and gender were matched, were examined for the presence of serological evidence of chronic hepatic disease, hepatitis B surface antigen (HBsAg) and anti-HCV seropositivity. RESULTS None of the patients with OL or control subjects had antibodies to HCV or HBsAg. All patients with OL and control subjects had normal liver function. CONCLUSION The present data indicate that patients with OL resident in Serbia do not have evidence of HCV or HBV infection.

Abstract
Echo-planar diffusion-weighted (DW) magnetic resonance (MR) imaging was used to evaluate changes in the parotid glands during gustatory stimulation. The study protocol was approved by the local ethics committee, and informed consent was obtained from all volunteers. Twelve healthy volunteers (five women, seven men) with a median age of 25 years (range, 22-30 years) were examined with a 1.5-T MR unit. A DW MR imaging sequence was performed once at rest and continuously repeated over a mean period of 26 minutes (range, 24-28 minutes) during salivary stimulation with a tablet of ascorbic acid given orally. During the first 5 minutes (range, 1 minute 30 seconds--7 minutes 30 seconds) of salivary stimulation, a decrease in apparent diffusion coefficient (ADC) was observed in both the parotid (P = .0001) and the submandibular (P = .0004) glands in all volunteers. During the following 15 minutes, a steady increase in ADC from the baseline value was noted for the parotid glands (P = .0022), and peak ADC was reached a median of 21 minutes (range, 14-21 minutes) after the start of gustatory stimulation. The ADC of the submandibular glands did not increase significantly after the start of gustatory stimulation compared with the ADC at baseline. In conclusion, DW MR imaging allows physicians to noninvasively demonstrate functional changes in the salivary glands.

Abstract
Salivary gland disease gives rise to salivary gland enlargement, pain, and prolonged xerostomia (dry mouth). Xerostomia is the most common long-standing problem for the majority of affected patients. There are many causes of dry mouth, with long-standing xerostomia being a particular problem in Sjögren's syndrome and after radiation to the head and neck region. Xerostomia is usually managed with saliva substitutes, but a large number of potential systemic therapies of long-standing xerostomia now exist. Some-particularly immunosuppressants-are of fundamental interest for the potential reduction of gland damage in Sjögren's syndrome but as yet are of limited clinical usefulness. Others, particularly pilocarpine and cevimeline, are, or have the potential to be, clinically useful in stimulating salivation by virtue of their action on cholinergic receptors.
