Imaging Activated-T-Lymphocytes in the Salivary Glands of Patients with Sjögren's Syndrome by 99mTc-Interleukin-2: Diagnostic and Therapeutic Implications. J Clin Med 2022; 11:jcm11154368. [PMID: 35955984 PMCID: PMC9369053 DOI: 10.3390/jcm11154368] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 07/23/2022] [Accepted: 07/25/2022] [Indexed: 12/12/2022] Open
Abstract
Background: Sjögren’s syndrome (SS) is a progressive autoimmune disease characterized by local mononuclear cell infiltration of the salivary and lachrymal glands. Labial biopsy demonstrates local infiltration by Th1 cells that produce pro-inflammatory cytokines, such as interleukin-2 (IL2). The aim of this study was to assess the utility of 99mTc-labelled-IL2 (99mTc-IL2) in evaluating in vivo the extent and severity of lympho-mononuclear cell infiltration in the salivary glands of patients with SS. Methods: We investigated 48 patients with primary SS and 27 control subjects using 99mTc-IL2 scintigraphy. Furthermore, in a subgroup of 30 patients, we also performed 99mTc-pertechnetate scintigraphy (99mTcO4−) for evaluation of the salivary gland function. Results: 99mTc-IL2 uptake in the salivary glands of SS patients was higher than in the control subjects (1.30 ± 0.16 vs. 0.83 ± 0.08 for parotids and 1.36 ± 0.15 vs. 1.16 ± 0.07 for submandibular glands; p < 0.0001). The salivary gland uptake of 99mTc-IL2 in patients with a longer history of disease was lower compared with the recently diagnosed patients. A significant direct correlation was found between the uptake of 99mTc-IL2 and histology. Conclusions: 99mTc-IL2 scintigraphy showed that the degree of lymphocytic infiltration of major salivary glands is variable in patients with different disease durations. Patients with a high 99mTc-IL2 uptake could be efficiently treated with immuno-modulatory drugs and the efficacy of treatment could be followed-up by 99mTc-IL2 scintigraphy.

Abstract
BACKGROUND/OBJECTIVES The present controlled sialographical study was conducted to learn more from the horizontal and vertical symmetry of the ductal lesions of the major salivary glands in primary (pSS) and secondary (sSS) forms of the disease. MATERIALS AND METHODS A total of 98 patients (38 pSS patients, 38 sSS patients, 22 control subjects) were included in the study. Contrast radiography of both parotid and submandibular glands was performed within the same session. A 6-point scoring system allowed summary indexes for each of the glands to be calculated. RESULTS Pansialography was accomplished within 30 min each. The sparsity of the branching pattern of the ducts was the most frequent pathological finding. In pSS, horizontal symmetry was more pronounced in the parotid glands, whereas in sSS it was more pronounced in the submandibular glands. The most discriminating features were the width of the peripheral ducts in the parotid and the number of acinar dilatations in the submandibular glands. The most advanced lesions were found in the left parotid gland. CONCLUSION The peripheral ducts are more affected by SS than the main excretory duct. There is a tendency for asymmetric involvement of the parotid glands in pSS and of the submandibular glands in sSS. Parotid glands are globally more involved than submandibular glands. Differential diagnosis between pSS and sSS cannot be accomplished by means of pansialography alone. Left parotid sialography is recommended for routine use.

Abstract
Three-dimensional imaging of the mucosa of the lower lip and labial minor salivary glands is demonstrated in vivo using swept source optical coherence tomography (OCT) system at 1310 nm with modified interface. Volumetric data sets of the inner surface of the lower lip covering ~230 mm(2) field are obtained from patients with Sjögren's syndrome and a control group. OCT enables high-resolution visualization of mucosal architecture using cross-sectional images as well as en-face projection images. Comprehensive morphometry of the labial minor salivary glands is performed, and statistical significance is assessed. Statistically significant differences in morphometric parameters are found when subgroups of patients with Sjögren's syndrome are analyzed.

Abstract
Introduction Decreased vascular responses to salivary gland stimulation are observed in Sjögren's syndrome patients. We investigate whether impaired vascular responses to parasympathetic stimulation and muscarinic receptor activation in salivary glands parallels hyposalivation in an experimental model for Sjögren's syndrome. Methods Blood flow responses in the salivary glands were measured by laser Doppler flowmeter. Muscarinic receptor activation was followed by saliva secretion measurements. Nitric oxide synthesis-mediated blood flow responses were studied after administration of a nitric oxide synthase inhibitor. Glandular autonomic nerves and muscarinic 3 receptor distributions were also investigated. Results Maximal blood flow responses to parasympathetic stimulation and muscarinic receptor activation were significantly lower in nonobese diabetic (NOD) mice compared with BALB/c mice, coinciding with impaired saliva secretion in nonobese diabetic mice (P < 0.005). Nitric oxide synthase inhibitor had less effect on blood flow responses after parasympathetic nerve stimulation in nonobese diabetic mice compared with BALB/c mice (P < 0.02). In nonobese diabetic mice, salivary gland parasympathetic nerve fibres were absent in areas of focal infiltrates. Muscarinic 3 receptor might be localized in the blood vessel walls of salivary glands. Conclusions Impaired vasodilatation in response to parasympathetic nerve stimulation and muscarinic receptor activation may contribute to hyposalivation observed in nonobese diabetic mice. Reduced nitric oxide signalling after parasympathetic nerve stimulation may contribute in part to the impaired blood flow responses. The possibility of muscarinic 3 receptor in the vasculature supports the notion that muscarinic 3 receptor autoantibodies present in nonobese diabetic mice might impair the fluid transport required for salivation. Parasympathetic nerves were absent in areas of focal infiltrates, whereas a normal distribution was found within glandular epithelium. Trial registration The trial registration number for the present study is 79-04/BBB, given by the Norwegian State Commission for Laboratory Animals.

Abstract
Abnormal findings on salivary gland scintigraphy (SGS) are part of the classification criteria for Sjøgren's syndrome (SS), but SGS is operator dependent and poorly standardised. We studied the use of quantitative data on the uptake, concentration and excretion of the four major salivary glands in the evaluation of sicca patients. During an initial clinical evaluation for sicca symptoms (mean duration, 51 months), 24 subjects were classified as either SS (n = 8) or isolated sicca (IS; n = 16). SGS was then performed after i.v. injection of 200 MBq pertecnetat. Digitalised quantitative data on time-to-peak uptake (Tmax), peak tracer distribution (C%) and stimulated excretion (E%) were calculated from time-activity curves and compared between groups and controls (n = 8) and correlated to clinical data. Statistical analysis was performed with non-parametric tests. SS patients had longer Tmax in both parotic glands (18.1 min; p < 0.01)) and both submandibular glands (mean 13.7 min, p < 0.05); whereas Tmax in IS patients was similar as in controls in both parotic (10.4 min; p > 0.2) and submandibular glands (9.4 min; p > 0.4). C% was significantly lower in the parotic glands of both the SS and the IS group compared to the controls (p < 0.01). E% was significantly reduced in SS patients (16.3% for parotic and 17.4% for submandibular glands; p < 0.01); whereas in the IS patients, excretion (32, 2% for parotic and 26, 9% for submandibular glands) was similar from all glands as in the control groups (35, 2% for parotic and 27, 8% for submandibular glands). No correlation was found between these SGS results and age, focus score, erythrocyte sedimentation rate, serum creatinin or immunoglobulin levels. No IS patient progressed to full-blown pSS during the 4 years of follow-up. Quantitative SGS data are useful and objective tools to distinguish patients with SS.

Abstract
BACKGROUND Salivary gland dysfunction is one of the key manifestations of Sjögren's syndrome. OBJECTIVES (1) To assess prospectively loss of function of individual salivary glands in patients with primary and secondary Sjögren's syndrome in relation to disease duration and use of immunomodulatory drugs. (2) To study changes in sialochemical and laboratory values and subjective complaints over time. METHODS 60 patients with Sjögren's syndrome were included in this study. Whole and gland-specific saliva (parotid and submandibular/sublingual (SM/SL)), samples were collected at baseline and after a mean of 3.6 (SD 2.3) years of follow-up. Disease duration was recorded for all patients. RESULTS Patients with Sjögren's syndrome with short disease duration had significantly higher stimulated flow rates at baseline than those with longer disease duration (p<0.05). When compared with healthy controls, the decrease in SM/SL flow rates at baseline was more prominent than that in parotid flow rates (p<0.05). Over time, there was a significant further decrease of stimulated flow rates, especially of the parotid gland, accompanied by increasing problems with swallowing dry food (p<0.05). The decrease was independent of the use of corticosteroids or disease-modifying antirheumatic drugs (DMARDs). Sialochemical variables remained stable. CONCLUSIONS Early Sjögren's syndrome is characterised by a decreased salivary gland function (parotis>SM/SL), which shows a further decrease over time, regardless of the use of DMARDs or steroids. Patients with Sjögren's syndrome with longer disease duration are characterised by severely reduced secretions of both the parotid and SM/SL glands. These observations are relevant for identifying patients who would most likely benefit from intervention treatment.

Abstract
In the past sicca syndromes were attributed to destruction of glandular tissue. It is now thought that cytokines, autoantibodies, and parasympathetic nervous system dysfunction all have an important role in the xerostomia and xerophthalmia in Sjögren's syndrome.

Abstract
OBJECTIVE Despite the availability of many new imaging procedures, sialography has, after decades of use, maintained its status as the imaging procedure of choice for evaluating the oral component of Sjögren syndrome (SS). In this study, the clinical value of sialography as a diagnostic tool in SS was explored by assessing its diagnostic accuracy, observer bias, and staging potential. METHODS One hundred parotid sialograms were interpreted independently in a blinded fashion by 2 trained and 2 expert observers. Sialograms were derived from a group of consecutive patients referred for diagnostics of SS. Patients were categorized as SS and non-SS by the revised European classification criteria. RESULTS Trained observers reached a sensitivity of 95 and a specificity of 33% for SS by sialogram, whereas expert observers reached a sensitivity of 87 and a specificity of 84%. There was only "fair" interobserver agreement between trained and expert observers, whereas both expert observers showed "good" agreement with one another, according to Cohen's kappa. Intraobserver agreement was "good" to "very good" for all observers. The 4 different gradations of sialectasia, ie, punctate, globular, cavitary, and destructive, showed a weak but significant correlation with the duration of oral symptoms. CONCLUSIONS This study markedly shows that the diagnostic value of parotid sialography for diagnosing SS greatly depends on the skills of the observer, implying that sialography lacks general applicability as a diagnostic tool in SS and requires specific expertise. Nevertheless, given its potentially high sensitivity and specificity in diagnosing SS as well as its useful staging potential, sialography still has its use in the evaluation of the oral component of SS.

Abstract
Sjögren syndrome (SS) is an inflammatory disease of the exocrine glands. Although not always present, signs and symptoms of dry eyes and xerostomia are characteristic features of SS. Oral dryness is one of the most important data of patients with SS. Several sets of criteria have been published; however, there is no definitive agreement concerning which is the most useful. In addition to its various clinical manifestations, lack of understanding of the causes of SS delays prompt diagnosis. Histologically, the salivary gland shows a characteristic lymphocytic infiltrate, which is implicated in the destruction of gland cells. Saliva performs an important role in maintaining and protecting oral health. Deficient quality and quantity of saliva have a detrimental consequence for dental and oral health. In some patients, appropriate information regarding dry mouth care is not offered because most professionals either neglect or ignore adequate attention to oral health. Therefore, lack of treatment is frequent. Medical and dental studies that focus on the oral aspects of diagnosis, consequences, and treatment of SS are commented on. Diagnostic methods used for the oral component are also reviewed. The role of the oral tests developed to diagnose SS is assessed, especially tests used by the majority of criteria. Impairment of salivary secretion increases the risk of developing oral diseases; the therapeutic modalities designed to ameliorate these damages by increasing salivary output or by substitution of saliva are reviewed. We discuss published prevention techniques to diminish dental, periodontal, and soft tissue infections.

Abstract
Primary Sjögren's syndrome (pSS) is a chronic inflammatory systemic autoimmune disease affecting the exocrine glands and predominantly the salivary and lacrimal glands. The impaired gland function is assumed to be a result of progressive lymphocyte-mediated destruction of the exocrine gland tissue leading to the cardinal manifestations, hyposalivation and keratoconjunctivitis sicca (KCS), as well as devastating symptoms of oral and ocular dryness. Although primarily characterised as an exocrine dysfunction, non-exocrine organs may also be affected. The onset and course of pSS is usually insidious but may develop into a disabling disease, which profoundly affects the patient's general well being and quality of life. Moreover, pSS may even evolve into a lymphoid malignancy. The aetiology of pSS remains unknown but the pathogenesis of exocrine cell damage is apparently multi-factorial, including immunological, genetic, hormonal and viral components. Recent research also includes neurogenic aspects of exocrine gland dysfunction, including the interference of immune mediators with glandular response to neurotransmitters released from nerve fibres. pSS usually affects middle-aged women and the female:male ratio is 9:1. The prevalence varies from 0.29-4.8%, depending on the population sampled and the diagnostic criteria used. At present, there are no specific diagnostic tests for pSS and no universally accepted diagnostic criteria. The current therapy is primarily symptomatic. This review focuses on the current oral clinical, diagnostic, pathogenic and therapeutic aspects of pSS.

Abstract
OBJECTIVES To investigate the occurrence of and risk factors for focal sialadenitis in patients with rheumatoid arthritis (RA), mixed connective tissue disease (MCTD), ankylosing spondylitis (AS), and spondyloarthropathy (SpA). METHODS A total of 85 patients (25 with RA, 19 with MCTD, 19 with AS, 22 with SpA) participated in the study. Each patient filled out a questionnaire for eye and oral symptoms and for the use of medication, and was interviewed; other tests included Schirmer's test, laboratory tests, collection of unstimulated and stimulated whole saliva, and minor salivary gland biopsy. A focus score of > or =1 was regarded as an indicator of focal sialadenitis. RESULTS Focal sialadenitis was observed in 68% (57/84) of all patients. It affected 80% (20/25) of the patients with RA, 94% (17/18) of those with MCTD, 58% (11/19) of those with AS, and 41% (9/22) of those with SpA (chi(2) test, p=0.0013). Salivary secretion correlated negatively with the focus scores-that is, severity of focal sialadenitis. Patients with focal sialadenitis had both decreased salivary secretion and decreased tear secretion significantly more often than did patients without (chi(2) test, p=0.0074 and p=0.048 respectively). Patients with positive rheumatoid factor (RF), antinuclear antibodies (ANA), or SSA or SSB antibodies had sialadenitis significantly more often than did patients with negative antibodies. In the subgroup of patients with AS or SpA, no associations were found between focal sialadenitis and the presence of these antibodies. CONCLUSION In addition to patients with RA or MCTD, focal sialadenitis also affects a very high proportion of patients with AS or SpA. Focus scores are significantly higher in patients with RA or MCTD than in those with AS or SpA. A significant association exists between focal sialadenitis and RF, ANA, SSA and SSB. However, in the subgroup of patients with AS or SpA, no associations were found between focal sialadenitis and serological markers or clinical symptoms.

Abstract
Parotid saliva from patients with rheumatoid arthritis and Sjögren's syndrome contains elevated levels of multiple anionic proteins of pI approximately 3.75-4.75 and Mr approximately 32,000. Further studies on these components involving narrow range pH 3.5-5.0 immobilized pH gradients (IPGs) and two-dimensional (2D) electrophoresis with narrow- or broad-range IPGs in the first dimension have confirmed their association with these disorders. Immunoblotting showed that these proteins include multiple forms of tissue kallikrein. Treatment with neuraminidase results in removal of these anionic substances from the pH 3.75-4.75 region of gels, thereby indicating that heterogeneity arises from differences in sialation of the carbohydrate residues. The results of treatment with endo-beta-N-acetylglucosaminidase (Endo F) or peptide N-glycosidase (PNGase F) and comparison of the results with studies on human urinary kallikrein suggest that proteins other than kallikrein may also comigrate in the anionic region of gels and that deglycosylation of kallikrien is incomplete in the experimental conditions used, probably because of inadequate denaturation. The paper also reviews the limitations of current criteria used in the investigation of salivary gland function associated with connective tissue disorders and the diagnosis of these. It assesses the potential of electrophoresis in forming the basis of new diagnostic techniques and furthering the understanding of the nature of these diseases. The findings presented in this paper could make a key contribution to this.

Abstract
A case of primary sialoangiectasia, which in this case was initially misdiagnosed as Sjögren's syndrome, is described. Other diseases, including HIV infection, psoriatic arthritis, and acute parotitis, may cause glandular changes similar to the changes found in the syndrome. Therefore, sialography must be combined with other methods of assessment of the oral cavity when suspicion is high for Sjögren's syndrome. Properly applied, sialography provides essential information regarding the severity of glandular damage and the progression of the disease.

Abstract
PURPOSE Three decades of work to enhance the diagnostic accuracy of salivary scintigraphy have generated various plausible decision criteria. This study evaluates four commonly cited numeric indices in studies of xerostomic populations and how accurately they identify Sjögren's syndrome, chronic sialadenitis, radiation sialadenitis, and drug effects and distinguish each from the other. METHODS Stimulated dynamic salivary scintigraphy was performed on 295 xerostomic patients and on 31 controls. The nonparametric area under the receiver operating characteristic curves expressed the diagnostic accuracy of the following scintigraphic indices: the parotid:submandibular ratio of unstimulated glandular activity, the peak:baseline uptake ratio, its time of occurrence, and the stimulated excretion fraction. RESULTS The stimulated excretion fraction distinguished Sjögren's syndrome and radiation sialadenitis from healthy states with respective accuracies of 0.78 and 0.90. The maximum diagnostic payoff in Sjögren's syndrome occurred at a cutoff of 73%, yielding a 73% rate of test sensitivity and a 73% rate of specificity. The other three indices were not useful. Even the stimulated excretion fraction performed indifferently or poorly in most other diagnostic tasks. CONCLUSIONS In the scintigraphic examination of xerostomic and healthy populations, an acceptable diagnostic utility of the stimulated excretion fraction was evident only in Sjögren's syndrome and radiation sialadenitis. When presented with differential diagnostic alternatives not involving radiation sialadenitis, none of the four numeric indices performed acceptably.

Abstract
We present a case of a 15-year-old girl with bilateral parotid and sub-mandibular salivary gland enlargement as the sole presentation of primary Sjögren's syndrome. The clinical, radiological, immunological and pathological features have been discussed. The relevant literature has been reviewed. To our knowledge this is the only reported case of Sjögren's syndrome presenting as multicystic disease with bilateral major salivary gland involvement.

Abstract
OBJECTIVES The purpose of this study was to examine the sialographic presentations of Sjögren's syndrome and SOX (sialadenitis, osteoarthritis, and xerostomia) syndrome and to establish whether changes in duct dimensions were a feature of these conditions. STUDY DESIGN The sialograms of 17 patients with Sjögren's syndrome, 18 patients with SOX syndrome, and 19 patients with no salivary gland disease were examined. Through the use of an A010 Solitaire Image Analysis System, ductal diameters were measured. The films were then assessed subjectively. RESULTS There was more sialectasis seen in the patients with Sjögren's syndrome than in the SOX group (chi-squared test: p < 0.01). There were no differences in duct diameter between the three groups. Control subjects with normal glands were shown to have narrower main ducts than has been previously reported, with an age-related widening of 1 degree and 2 degrees ducts. CONCLUSIONS Sialectasis is not a feature of SOX syndrome. Ductal narrowing should not be thought of as a feature of either SOX or Sjögren's syndrome.

Abstract
Parotid sialography has been used for many years as a means of assessing salivary glands in Sjögren's syndrome (SS), and it is occasionally used as a diagnostic criterion for the salivary component of SS. To assess its diagnostic effectiveness, we reviewed studies in which sialography was applied to patients with SS and control subjects for the purpose of estimating its diagnostic sensitivity and specificity or comparing it with other means of assessing salivary glands. Sialography appears to be diagnostically less sensitive but more specific than salivary flow rate measurement and more sensitive but less specific than labial salivary gland (LSG) biopsy. Such calculations are based on the diagnosis of SS established in each study, but the various studies used widely different criteria to establish that diagnosis. Therefore, these calculations are not based on a consistent standard, and comparison between the calculations may be misleading, which underscores the need to develop internationally accepted diagnostic criteria for SS. Studies conducted so far have not shown that parotid sialography is either a sensitive indicator of the salivary component of SS or more closely associated than LSG biopsy with keratoconjunctivitis sicca, the only other component of primary SS with which ultimately to assess diagnostic specificity.

Abstract
OBJECTIVE To determine the association between patterns of inflammation in labial salivary glands (LSG) and the ocular component of Sjögren's syndrome (SS). METHODS We classified LSG biopsy specimens from 618 patients with suspected SS as showing focal lymphocytic sialadenitis (FLS), other chronic sialadenitis (CS), or other diagnoses. We then determined the association of the other component of primary SS, keratoconjunctivitis sicca (KCS), with FLS, CS, parotid flow rate, and xerostomia. RESULTS FLS, rather than CS, was associated with a diagnosis of KCS (chi 2 = 191, P < 0.0001). The severity of KCS correlated directly with the severity of FLS (r = 0.52, P < 0.0001), but not of CS, and correlated inversely with parotid flow rate in those patients who had FLS (r = -0.29), but not in those who had CS (r = -0.03). Xerostomia was marginally associated with KCS (chi 2 = 5, P = 0.02). CONCLUSION The stronger KCS association found in patients whose LSG biopsies show FLS makes FLS the best criterion presently available for diagnosing the salivary component of SS. CS is a common feature of labial salivary glands but is neither associated with SS nor an end stage of primary SS. Histopathologic examination of salivary tissue is currently essential for diagnosing primary SS as well as secondary SS in which KCS is lacking, especially cases to be included in studies of SS.

Abstract
The major salivary glands were examined with 99m-Tc-pertechnetate scintigraphy in randomly selected subjects with (n = 30) and without (n = 12) symptoms of dry mouth and/or eyes, and in patients with primary Sjögren's syndrome (1 degree SS, n = 17). The scans were quantitatively evaluated and compared to other objective tests used to diagnose 1 degree SS. As compared with those for asymptomatic subjects, most values for the scintigraphic variables were non-significantly lower for symptomatic subjects and the time-activity curves were slightly flatter for all major salivary glands. In patients with 1 degree SS most values for the scintigraphic variables were significantly lowered and the submandibular glands were the glands most affected, as reflected in a flat time-activity curve, while the parotid glands were mainly affected during stimulated secretion. The scintigraphic variables correlated with the self-rated dryness of mouth in symptomatic subjects and with the abnormality of sialometry results in patients with 1 degree SS. We conclude that salivary gland scintigraphy is a sensitive and valid method to measure salivary gland function and abnormalities.

Abstract
We report a case of Sjögren's syndrome characterized by keratoconjunctivitis sicca, parotid swelling, reduced salivary flow, and abnormalities on nuclear scanning. Two labial gland biopsies showed complete atrophy. Biopsy of an enlarged submandibular gland revealed lymphoid follicles and glandular replacement consistent with the diagnosis of Sjögren's syndrome. This case supports the concept that a negative finding on labial biopsy does not rule out a diagnosis of Sjögren's syndrome.

Abstract
We report here the sialographic appearances of the submandibular gland in both primary and secondary Sjögren's syndrome (SS). In order to compare these with those of the parotid gland, we defined new criteria for the staging for SS based on the degree of depiction of the peripheral ducts. In 24 out of 74 cases the submandibular sialogram showed more advanced, destructive disease compared with the parotid. This study suggests that although SS involves the parotid gland first, it progresses in the submandibular gland more rapidly.

Abstract
The initial evaluation of 25 patients suspected of suffering from Sjögren's syndrome (SS) disclosed that sialopenia and glandular atrophy without focal sialo-adenitis was the second most common cause, after SS itself, of patient complaints. This emphasizes the importance of conclusive diagnostic criteria to prevent overdiagnosis and to form a sound basis for management of xerostomia patients. We found that at the time of diagnostic evaluation, the dental status of our SS patients did not differ from that of the normal Finnish population. This suggests that SS patients can greatly benefit from adequate dental care, assuming that attention is paid to early diagnosis and management. Accordingly, the diagnostic and therapeutic approach needs to be multidisciplinary. We present our current programme for oral and dental care of xerostomia patients and the results of an open trial with Sulfarlem (trithioparamethoxyphenylpropene) which was found not to be the drug of choice in the treatment of dry mouth associated with SS.
