Abstract
Sjögren's disease (SjD) is a chronic, systemic autoimmune disease with no approved disease-modifying therapies. Dazodalibep (DAZ), a novel nonantibody fusion protein, is a CD40 ligand antagonist that blocks costimulatory signals between T and B cells and antigen-presenting cells, and therefore may suppress the wide spectrum of cellular and humoral responses that drive autoimmunity in SjD. This study was a phase 2, randomized, double-blinded, placebo (PBO)-controlled trial of DAZ with a crossover stage in two distinct populations of participants with SjD. Population 1 had moderate-to-severe systemic disease activity and population 2 had an unacceptable symptom burden and limited systemic organ involvement. All participants had a diagnosis of SjD, with 21.6% and 10.1% having an associated connective tissue disease (rheumatoid arthritis or systemic lupus erythematosus) in populations 1 and 2, respectively. The remaining participants would be considered as having primary Sjögren's syndrome. The primary endpoint for population 1 (n = 74) was the change from baseline in the European League Against Rheumatism Sjögren's Syndrome Disease Activity Index at day 169. The primary endpoint for population 2 (n = 109) was the change from baseline in the European League Against Rheumatism Sjögren's Syndrome Patient Reported Index at day 169. The primary endpoints (least squares mean ± standard error) were achieved with statistical significance for both population 1 (DAZ, -6.3 ± 0.6; PBO, -4.1 ± 0.6; P = 0.0167) and population 2 (DAZ, -1.8 ± 0.2; PBO, -0.5 ± 0.2; P = 0.0002). DAZ was generally safe and well tolerated. Among the most frequently reported adverse events were COVID-19, diarrhea, headache, nasopharyngitis, upper respiratory tract infection, arthralgia, constipation and urinary tract infection. In summary, DAZ appears to be a potential new therapy for SjD and its efficacy implies an important role for the CD40/CD40 ligand pathway in its pathogenesis.

Treatment of non-systemic Sjögren's syndrome: Potential prevention of systematization with immunosuppressant agent/biotherapy. J Transl Autoimmun 2024; 8:100238. [PMID: 38496268 PMCID: PMC10940795 DOI: 10.1016/j.jtauto.2024.100238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Revised: 02/27/2024] [Accepted: 02/28/2024] [Indexed: 03/19/2024] Open
Abstract
Sjögren's syndrome (SS) is a systemic autoimmune pathology manifested mainly by a dry syndrome, intense asthenia and arthromyalgia. Systemic manifestations may also occur. Since 2019, immunosuppressant agents (IS) or biotherapies are recommended only for patients with systemic involvement. However, before 2019, in some cases, paucisymptomatic patients had been treated with IS/biotherapies, often off-label. Objective: We propose to evaluate the benefit and safety of using IS/biotherapy in patients with SS without systemic involvement. Methods: We retrospectively collected the clinical records of all patients with SS diagnosed according to ACR/EULAR diagnostic criteria followed up between January 1980 and October 2023 at Grenoble University Hospital (France). Results: Eighty-three patients were included: 64 with an initially non-systemic form. Of these patients with an initially non-systemic form, 24 were treated with IS/biotherapy. None of them developed secondary systematization, whereas 11 out of 40 patients in the untreated group did (p < 0.05). On the other hand, IS/biotherapy did not appear to improve dry syndrome. There were no serious adverse events. Conclusion: Early introduction of an IS/biotherapy treatment appears to provide a benefit for the patient without side effects.

Abstract
Sjögren disease (SD) is a chronic, autoimmune disease of unknown aetiology with significant impact on quality of life. Although dryness (sicca) of the eyes and mouth are the classically described features, dryness of other mucosal surfaces and systemic manifestations are common. The key management aim should be to empower the individual to manage their condition-conserving, replacing and stimulating secretions; and preventing damage and suppressing systemic disease activity. This guideline builds on and widens the recommendations developed for the first guideline published in 2017. We have included advice on the management of children and adolescents where appropriate to provide a comprehensive guideline for UK-based rheumatology teams.

Identification of outcome domains in primary Sjögren's disease: A scoping review by the OMERACT Sjögren disease working group. Semin Arthritis Rheum 2024; 65:152385. [PMID: 38340608 DOI: 10.1016/j.semarthrit.2024.152385] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 12/29/2023] [Accepted: 01/03/2024] [Indexed: 02/12/2024]
Abstract
OBJECTIVES Sjögren's disease (SjD) is a heterogenous disease with a wide range of manifestations, ranging from symptoms of dryness, fatigue, and pain, to systemic involvement. Considerable advances have been made to evaluate systemic activity or patient-reported outcomes, but most of the instruments were not able to assess all domains of this multifaceted disease. The aim of this scoping review was to generate domains that have been assessed in randomized controlled trials, as the first phase of the Outcome Measures in Rheumatology (OMERACT) process of core domain set development. METHODS We systematically searched Medline (Pubmed) and EMBASE between 2002 and March 2023 to identify all randomized controlled trials assessing relevant domains, using both a manual approach and an artificial intelligence software (BIBOT) that applies natural language processing to automatically identify relevant abstracts. Domains were mapped to core areas, as suggested by the OMERACT 2.1 Filter. RESULTS Among the 5,420 references, we included 60 randomized controlled trials, focusing either on overall disease manifestations (53%) or on a single organ/symptom: dry eyes (17%), xerostomia (15%), fatigue (12%), or pulmonary function (3%). The most frequently assessed domains were perceived dryness (52% for overall dryness), fatigue (57%), pain (52%), systemic disease activity (45%), lacrimal gland function (47%) and salivary function (55%), B-cell activation (60%), and health-related quality of life (40%). CONCLUSION Our scoping review highlighted the heterogeneity of SjD, in the study designs and domains. This will inform the OMERACT SjD working group to select the most appropriate core domains to be used in SjD clinical trials and to guide the future agenda for outcome measure research in SjD.

Abstract
Chronic cholestasis is the hallmark clinical feature of primary biliary cholangitis. In addition to progressive liver damage, chronic cholestasis can lead to serious complications, many of which occur outside the liver. Bile acids are ligands for nuclear hormone receptors, and alterations in their concentration disrupt normal functioning of numerous different cell types. This article discusses the clinical presentation, pathophysiology, and management of pruritus (itching), fatigue, osteoporosis, hyperlipidemia, fat-soluble vitamin deficiencies, malignancies, cardiac dysfunction, bacterial cholangitis, cholemic (bile cast) nephropathy, and Sicca syndrome.

Abstract
Salivary gland hypofunction (SGH) caused by systemic disease, drugs, aging, and radiotherapy for head and neck cancer can cause dry mouth, which increases the risk of disorders such as periodontitis, taste disorders, pain and burning sensations in the mouth, dental caries, and dramatically reduces the quality of life of patients. To date, the treatment of SGH is still aimed at relieving patients' clinical symptoms and improving their quality of life, and is not able to repair and regenerate the damaged salivary glands. Pluripotent stem cells (PSCs), including embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), and extended pluripotent stem cells (EPSCs), are an emerging source of cellular therapies that are capable of unlimited proliferation and differentiation into cells of all three germ layers. In recent years, the immunomodulatory and tissue regenerative effects of PSCs, their derived cells, and paracrine products of these cells have received increasing attention and have demonstrated promising therapeutic effects in some preclinical studies targeting SGH. This review outlined the etiologies and available treatments for SGH. The existing efficacy and potential role of PSCs, their derived cells and paracrine products of these cells for SGH are summarized, with a focus on PSC-derived salivary gland stem/progenitor cells (SGS/PCs) and PSC-derived mesenchymal stem cells (MSCs). In this Review, we provide a conceptual outline of our current understanding of PSCs-based therapy and its importance in SGH treatment, which may inform and serve the design of future studies.

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
In this study, we evaluated the effectiveness of a single-dose oral pilocarpine administration on tear film (TF), as well as dry eye and dry mouth symptoms, in 53 eyes of 27 Sjögren syndrome (SS) patients who were experiencing dry mouth. To evaluate the changes in tear volume, a digital video-meniscometer was used to measure the radius of the lower central tear meniscus curvature (R, mm) of each eye at prior to the administration of 5 mg oral pilocarpine, and at 15 (R:(15)), 30 (R:(30)), and 60 (R:(60)) minutes after administration. The fluorescein breakup time (FBUT, seconds) and ocular and oral dryness symptoms were evaluated before and at 60 min after administration using a visual analogue scale (VAS, mm). A significant increase in R was observed at 15 and 30 min after administration compared to that at prior to administration. FBUT showed significant improvement at 60 min after administration, and the VAS score for ocular and oral dryness symptoms was found to have decreased significantly at 60 min after administration. A single-dose administration of 5 mg oral pilocarpine had a beneficial effect on TF, as well as on ocular and oral dryness symptoms, in patients with SS.

Indeed, the clinical presentations are heterogeneous, and one must be able to identify prognostic markers to adapt the follow-up. In addition, there is no validated treatment. Nevertheless, international experts have been working for several years to establish recommendations to guide management. Since research in this field is extremely active, we anticipate the development of effective treatments for our patients in the near future.

The efficacy and safety of varenicline nasal spray for the management of dry eye signs: a systematic review and meta-analysis. BMC Ophthalmol 2023; 23:319. [PMID: 37452334 PMCID: PMC10347795 DOI: 10.1186/s12886-023-03069-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Accepted: 07/03/2023] [Indexed: 07/18/2023] Open
Abstract
BACKGROUND Dry eye disease (DED) is caused by a persistently unstable tear film leading to ocular discomfort and is treated mainly with tear supplementation. There is emerging evidence that nicotinic acetylcholine receptor (nAChR) agonists (e.g., varenicline and simpinicline) nasal sprays are effective for DED. Our systematic review and meta-analysis assessed the efficacy and safety of varenicline nasal spray (VNS) for DED treatment. METHODS The Medline, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched. Only randomized controlled trials (RCTs) that evaluated the efficacy of VNS versus placebo were included. The efficacy endpoint was the mean change in the anesthetized Schirmer test score (STS), a measure of basal tear production, from baseline. The safety endpoints were serious adverse events (SAEs) and adverse events (AEs). The standardized mean difference (SMD) was used for continuous outcomes, while the risk ratio (RR) was used to demonstrate dichotomous variables. The certainty of the evidence was rated utilizing the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The risk of bias assessment was conducted using the Revised Cochrane risk of bias tool for randomized trials. RESULTS Three RCTs (n = 1063) met the eligibility criteria. All RCTs had a low risk of bias. The meta-analysis found a statistically significant increase in the mean STS change from baseline on day 28. The pooled analysis found no significant difference between VNS and placebo in the frequency of SAEs and ocular AEs. However, VNS had a significant effect on developing nasal cavity-related AEs. CONCLUSION VNS caused a highly significant improvement regarding the efficacy endpoint but caused an increased frequency of some nasal cavity-related AEs (i.e., cough and throat irritation). However, it caused neither SAEs nor ocular AEs. Included studies had a low risk of bias.

Abstract
Sjögren's syndrome (SS) is an autoimmune disease characterized by the involvement of exocrine glands such as the salivary and lacrimal glands. The minor salivary glands, from which tissue samples may be obtained, are important for the diagnosis, evaluation of therapeutic efficacy, and genetic analyses of SS. In the onset of SS, autoantigens derived from the salivary glands are recognized by antigen-presenting dendritic cells, leading to the activation of T and B cells, cytokine production, autoantibody production by plasma cells, the formation of ectopic germinal centers, and the destruction of salivary gland epithelial cells. A recent therapeutic approach with immune checkpoint inhibitors for malignant tumors enhances the anti-tumor activity of cytotoxic effector T cells, but also induces SS-like autoimmune disease as an adverse event. In the treatment of xerostomia, muscarinic agonists and salivary gland duct cleansing procedure, as well as sialendoscopy, are expected to ameliorate symptoms. Clinical trials on biological therapy to attenuate the hyperresponsiveness of B cells in SS patients with systemic organ involvement have progressed. The efficacy of treatment with mesenchymal stem cells and chimeric antigen receptor T cells for SS has also been investigated. In this review, we will provide an overview of the pathogenesis of salivary gland lesions and recent trends in therapeutic approaches for SS.

Abstract
INTRODUCTION The Profile of Fatigue and Discomfort-Sicca Symptoms Inventory-Short Form (PROFAD-SSI-SF) is a 19-item patient-reported outcome (PRO) measure to assess pain, fatigue, and dryness in patients with primary Sjögren's syndrome (pSS). This analysis identified concepts important to measure, and evaluated the content validity and measurement properties of the PROFAD-SSI-SF, in patients with pSS. METHODS Qualitative analyses (GSK Study 208396) used transcripts from an online concept elicitation (CE) discussion forum with patients with pSS and interviews with key opinion leaders (KOLs) to finalize a disease model depicting important concepts for patients with pSS. Cognitive debriefing (CD) interviews with patients with pSS were conducted to further evaluate the content validity of the PROFAD-SSI-SF. Quantitative analyses (GSK Study 213253) used post hoc analyses of blinded data from a phase 2 trial to assess PROFAD-SSI-SF measurement properties. RESULTS The CE discussion forum (N = 46) revealed dryness (oral 87.0%, ocular 73.9%, cutaneous 37.0%, vaginal 23.9%, nasal 15.2%, otic 6.5%), pain (89.1%), and fatigue (87.0%) as the most reported symptoms. KOLs (N = 5) found the concepts identified in the disease model accurate and understandable, and confirmed that PROs used in pSS studies should focus on dryness, joint pain, and fatigue. In the CD interviews (N = 20), of the 19 participants asked, all found the PROFAD-SSI-SF easy to understand, and 14/19 items were considered relevant by ≥ 18/20 participants. The quantitative analyses found an acceptable fit of the PROFAD-SSI-SF factor structure, with adequate internal consistency, test-retest reliability, convergent validity with other PRO measures, known-groups validity with Patient Global Assessment, and ability to detect change in patients with pSS. CONCLUSION The final disease model confirmed that the PROFAD-SSI-SF assesses concepts that are relevant and important to patients with pSS. Our findings support the content validity and measurement properties of the PROFAD-SSI-SF as a fit-for-purpose PRO measure appropriate for use in clinical trials in patients with pSS. CLINICAL TRIAL REGISTRATION NUMBER FOR THE PHASE 2 TRIAL: Clinicaltrials.gov NCT02631538.

Abstract
The upper gastrointestinal (GI) tract is frequently involved in systemic sclerosis (SSc) and may impact quality of life, physical function and survival. Although we are currently very proactive in terms of screening for heart and lung involvement, patients with SSc are not routinely screened for GI involvement. This review details the available investigations for common upper GI symptoms in SSc, including dysphagia, reflux and bloating and provides advice as to how to integrate these investigations into current clinical care.

Abstract
Historically, boiled sweets have been recommended by ear, nose, and throat surgeons for their sialagogue effect in patients with sialolithiasis. This study presents an in vivo analysis of boiled sweets and solutions to determine sialagogue superiority. Six high-street boiled sweets (lemon sherbets, rhubarb sweets, mint humbugs, Werther's Original® (August Storck, Germany), Fox's Glacier Fruits® (Fox's Confectionery, Braunstone, Leicester, United Kingdom), and Chupa Chups® lollipops (Perfetti Van Melle, Breda, Netherlands)) and two solutions (malt vinegar and lemon juice) were compared to two controls (no sweet and inert plastic) in two healthy participants. Malt vinegar and lemon juice produced the highest salivary flow. The best-performing boiled sweets were Chupa Chups lollipops and lemon sherbet. Substances with the highest concentrations of citric or lactic acid were the best sialagogues. This pilot study provides a proof of concept for further investigation in this cohort of patients.

Abstract
The gastrointestinal tract (GI) is the second most affected organ system in individuals suffering from systemic/localized scleroderma (SSc) or localized scleroderma. SSc can affect any part of the GI, between the oral cavity and anorectum. The annual incidence of SSc in the United States is estimated to be 19.3 cases per million adults, with the highest incidence reported in people aged 44 to 55. Females are 5 times more likely than males to suffer from SSc. Morbidity and mortality rates associated with SSc are predominantly elevated among patients with GI manifestations. Esophageal and intestinal manifestations impact 90% and 40% to 70% of patients with systemic scleroderma, respectively. SSc patients are known to suffer from small bowel hypomotility and small intestinal bacterial overgrowth, which cause malabsorption and malnutrition, ultimately contributing to the 50% mortality rate. Fecal incontinence is a common symptom of SSc that can lead to depression. SSc patients may suffer from gastrointestinal complications that can negatively impact their quality of life on a daily basis. Multidisciplinary approaches are necessary for systematically managing gastrointestinal complications associated with SSc. A prospective study should focus on developing targeted therapies to improve recovery patterns and prognosis in cases of SSc. This article summarizes the epidemiology, commonly reported clinical manifestations, complications, and available treatments for treating GI pathology in SSc patients.

Abstract
Xerostomia is linked to an increased risk of dental caries, oral fungal infections, and speaking/swallowing difficulties, factors that may significantly degrade patients’ life, socially- or emotionally-wise. Consequently, there is an increasing interest in developing management approaches for confronting this oral condition, at which pilocarpine, a parasympathomimetic agent, plays a vital role. Although the therapeutic effects of orally administrated pilocarpine on the salivary gland flow and the symptoms of xerostomia have been proved by numerous studies, the systemic administration of this drug is affiliated with various adverse effects. Some of the typical adverse effects include sweating, nausea, vomiting, diarrhea, rhinitis, dizziness and increased urinary frequency. In this vein, new strategies to develop novel and effective dosage forms for topical (i.e., in the oral cavity) pilocarpine administration, in order for the salivary flow to be enhanced with minimal systemic manifestations, have emerged. Therefore, the purpose of the current review is to survey the literature concerning the performance of topical pilocarpine delivery systems. According to the findings, the topical delivery of pilocarpine can be regarded as the equivalent to systemic delivery of the drug, efficacy-wise, but with improved patient tolerance and less adverse effects.

Abstract
The number of cancer survivors are increasing and so are the oral toxicities from cancer therapy. Most patients receiving treatment for cancer develop some form of oral adverse events including, but not limited to, mucositis, opportunistic infections, dry mouth, and/or osteonecrosis of the jaw. One of the most common complications from head and neck cancer radiation therapy is salivary gland dysfunction (SGD). SGD is an umbrella term that includes the subjective sensation of dry mouth (xerostomia) and hyposalivation (objective reduction of the salivary flow rate). Dry mouth in cancer patients may lead to functional defects (e.g., eating, speaking, and swallowing), increase the risk of dental caries and oral candidiasis, and can have a negative effect on the nutritional and psychological status of the patients. The aim of this mini review was to summarize the current criteria for diagnosis and management of SGD associated with cancer treatment.

Abstract
BACKGROUND Aqueous deficiency dry eye disease is a chronic and potentially sight-threatening condition, that occurs due to the dysfunction of the lacrimal glands. The aim of this review was to describe the various recent developments in the understanding, diagnosis and treatment of lacrimal gland insufficiency in aqueous deficiency dry eye disease. METHODS A MEDLINE database search using PubMed was performed using the keywords: "dry eye disease/syndrome", "aqueous deficient/deficiency dry eye disease", "lacrimal gland" and "Sjogren's syndrome". After scanning through 750 relevant abstracts, 73 eligible articles published in the English language from 2016 to 2021 were included in the review. RESULTS Histopathological and ultrastructural studies have revealed new insights into the pathogenesis of cicatrising conjunctivitis-induced aqueous deficiency, where the lacrimal gland acini remain uninvolved and retain their secretory property, while significant ultrastructural changes in the gland have been observed. Recent advances in diagnosis include the techniques of direct clinical assessment of the lacrimal gland morphology and secretion, tear film osmolarity, tear film lysozyme and lactoferrin levels, tear film interferometry and lacrimal gland confocal microscopy. Developments in the treatment of aqueous deficiency dry eye disease, apart from the nanoparticle-based tear substitutes, include secretagogues like diquafosol tetrasodium and rebamipide, anti-inflammatory topical agents like nanomicellar form of cyclosporine and lifitegrast, scleral contact lenses, neurostimulation, and acupuncture for increasing the amount of tear production, minor salivary gland transplantation, faecal microbial transplantation, lacrimal gland regeneration and mesenchymal stem cell therapy. CONCLUSIONS Significant advances in the understanding, diagnosis and management of lacrimal gland insufficiency and its role in aqueous deficiency dry eye disease have taken place within the second half of the last decade. Of which, translational breakthroughs in terms of newer drug formulations and regenerative medicine are most promising.

Abstract
Pilocarpine-induced salivary secretion could serve as a nontherapeutic target engagement biomarker in a clinical setting to test the activity of an M3 positive allosteric modulator (PAM). The potentiating effect on the reactivity of the M3 receptor to the agonistic effect of pilocarpine would support the mechanism of action of an M3 PAM in a variety of therapeutic areas. The aim of this study was to determine the optimal pilocarpine dose needed for evaluation of this potentiating effect. Therefore, the effects of pilocarpine on salivary secretion rate and its pharmacokinetics were explored at single doses of 2.5, 5, and 10 mg of pilocarpine or placebo. The study also explored the test-retest variability of the pilocarpine-induced effects on salivary secretion. Pilocarpine caused a reproducible, dose-related increase in overall and maximum salivary secretion rate, in line with pilocarpine exposure. Oral doses of pilocarpine from 2.5 to 10 mg were safe and well tolerated, consistent with the published safety profile. These results support the use of pilocarpine in single-dose pharmacological challenge studies. The recommended dose for evaluating M3 PAM activity would be between 2.5 and 5 mg, showing a small increase in salivary secretion rate with room for further increase due to PAM activation.

Abstract
Objectives To determine the general condition of elderly xerostomia patients, we collected their background and medication data in order to potentially treat their xerostomia. It is critical to identify the drugs causing xerostomia in elderly patients. A total of 521 patients who were examined at the Xerostomia Clinic of Osaka University Dental Hospital were included in the study. We obtained patients’ data on age, sex, number of primary illnesses, Saxon test scores, oral moisture test, subjective symptoms, and drug types from their clinical records. Results The mean age of the patients was 65.2 ± 13.3 years. Although all patients exhibited xerostomia symptoms, there were a lot of patients without hyposalivation. With respect to medication, each elderly xerostomia patient took an average of 6.8 ± 4.4 medicines. A total of 26.1% of patients in their 70 s took more than ten number of drugs. In addition, the number of frequently used medication medicine was different between elderly and young patients. Most of the medicines had xerostomia as a side effect in medical package inserts. Moreover, the quantity of salivation significantly decreased in patients who took more than seven drugs in comparison with the patients who did not take medicine. Conclusions As patients age, the number of medications they take tends to increase, subsequently increasing their risk of xerostomia. For the health of the patients, it is critical that an accurate diagnosis is made. Clinical relevance To establish therapeutic strategies for treatment of xerostomia, this study provides new and important information that will help in the development of xerostomia medical treatment.

Xerostomia: an immunotherapy-related adverse effect in cancer patients. Support Care Cancer 2021; 30:1681-1687. [PMID: 34562169 DOI: 10.1007/s00520-021-06535-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Accepted: 08/31/2021] [Indexed: 12/19/2022]
Abstract
PURPOSE Xerostomia is an underrecognized adverse effect of immunotherapy (IO) that can significantly impact patients' quality of life by leading to poor nutritional status, dental caries, and oral candidiasis. The purpose of this case series was to describe the onset, severity, clinical course, and management of IO-induced xerostomia. METHODS This was a retrospective case series conducted at an outpatient cancer center. Data collection was conducted via chart review. The severity of dry mouth symptoms was graded using the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. RESULTS Six patients with advanced solid tumors who received a PD-1 inhibitor or PD-1/CTLA-4 inhibitor combination therapy were evaluated. The median time to onset of xerostomia was 4.5 months overall, though symptoms developed sooner in patients who received IO as subsequent-line therapy (median = 1.9 months). All patients developed other immune-related adverse events (IRAEs) such as hypothyroidism. Five patients (83%) had grade 2 dry mouth symptoms, and similarly, 5 patients eventually required prescription medications such as sialogogues and topical or systemic corticosteroids to alleviate symptoms. Two patients (33%) required interruptions in IO. All 3 patients who received cevimeline noticed improvement in symptoms, and one patient who received prednisone dosed at 1 mg/kg/day tapered over 5 weeks also experienced significant relief. CONCLUSION While the optimal management of IO-induced xerostomia has not yet been established by national guidelines, increased awareness can prompt faster initiation of supportive care measures that can prevent significant discomfort and poor oral intake. Thoughtful use of over-the-counter topical agents, sialogogues, corticosteroids, and treatment interruptions can help improve tolerability of this adverse effect.

Abstract
The sweat test is the gold standard for the diagnosis of cystic fibrosis (CF). The test utilizes iontophoresis to administer pilocarpine to the skin to induce sweating for measurement of chloride concentration in sweat. However, the sweat test procedure needs to be conducted in an accredited lab with dedicated instrumentation, and it can lead to inadequate sweat samples being collected in newborn babies and young children due to variable sweat production with pilocarpine iontophoresis. We tested the feasibility of using microneedle (MN) patches as an alternative to iontophoresis to administer pilocarpine to induce sweating. Pilocarpine-loaded MN patches were developed. Both MN patches and iontophoresis were applied on horses to induce sweating. The sweat was collected to compare the sweat volume and chloride concentration. The patches contained an array of 100 MNs measuring 600 μm long that were made of water-soluble materials encapsulating pilocarpine nitrate. When manually pressed to the skin, the MN patches delivered >0.5 mg/cm2 pilocarpine, which was double that administered by iontophoresis. When administered to horses, MN patches generated the same volume of sweat when normalized to drug dose and more sweat when normalized to skin area compared to iontophoresis using a commercial device. Moreover, both MN patches and iontophoresis generated sweat with comparable chloride concentration. These results suggest that administration of pilocarpine by MN patches may provide a simpler and more-accessible alternative to iontophoresis for performing a sweat test for the diagnosis of CF.

A Phase I, Open-label, Randomized, 2-Way Crossover Study to Evaluate the Relative Bioavailability of Intranasal and Oral Varenicline. Clin Ther 2021; 43:1595-1607. [PMID: 34456060 DOI: 10.1016/j.clinthera.2021.07.020] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2021] [Revised: 07/08/2021] [Accepted: 07/26/2021] [Indexed: 01/21/2023]
Abstract
PURPOSE To estimate the systemic bioavailability of OC-01 (varenicline) nasal spray, an investigational treatment for dry eye disease, relative to oral varenicline approved for smoking cessation. METHODS The Study to Evaluate the Relative Bioavailability of Varenicline Administered as OC-01 (Varenicline) Nasal Spray as Compared to Varenicline Administered Orally as Chantix (ZEN study) was a Phase I, open-label, randomized, single-center, 2-way crossover study. On day 1, 22 healthy participants were randomized 1:1 to a single intranasal dose of varenicline 0.12 mg in OC-01 nasal spray or a single oral dose of varenicline 1 mg. On day 15, all participants crossed over to receive a single dose of the alternate treatment. Plasma samples were collected for 6 days after each dose, and pharmacokinetic parameters were estimated using noncompartmental analysis. Tolerability was monitored throughout. FINDINGS After a single dose of intranasal varenicline 0.12 mg in OC-01 nasal spray, peak systemic exposure (mean plasma Cmax) was 0.34 ng/mL, which occurred at a median Tmax of 2.0 hours. In comparison, mean plasma Cmax after oral varenicline 1 mg was 4.63 ng/mL at a median Tmax of 3.0 hours. On the basis of geometric mean ratio point estimates, peak exposure (Cmax) and total exposure (AUC0-∞) after intranasal varenicline 0.12 mg were 7.0% and 7.5%, respectively, of the systemic exposure associated with oral varenicline 1 mg. Dose-normalized Cmax and AUC0-∞ for intranasal varenicline remained 39% and 33% lower versus oral varenicline, respectively. No new or unexpected tolerability signals were detected. IMPLICATIONS At its highest intended single dose in OC-01 nasal spray, intranasal varenicline delivered less drug to the systemic circulation than oral varenicline at its highest approved single dose.

Abstract
OBJECTIVES Various oral symptoms, including xerostomia and burning mouth syndrome, may occur in menopausal women. These symptoms reduce quality of life (QOL). However, the actual condition of xerostomia after menopause is not clear. The purpose of this study was to reveal the factors associated with xerostomia in perimenopausal women. METHODS Participants included 118 outpatients (mean age, 49.9 ± 3.2 years; range, 45-55 years) at a department of gynecology in Japan. Information was collected concerning age, medical history, medications, menstrual status, and history of treatment for climacteric symptoms. Oral symptoms, including xerostomia were evaluated with a 3-point scale. The climacteric symptom checklist for Japanese women and 36-Item Short-Form Health were used to evaluate climacteric symptoms and QOL, respectively. In addition, the volume of unstimulated saliva, oral moisture, salivary α-amylase, chromogranin A, and 17-β estradiol were measured. RESULTS Higher age, the total number of medications, psychotropic drug, hormone replacement therapy, treatment for climacteric symptoms, sticky mouth, burning sensation of tongue, dryness of nose and 14 of the 21 climacteric symptoms significantly affected xerostomia. In addition, treatment for climacteric symptoms, fall asleep but often awake at night, headaches and dryness of nose were significantly associated with xerostomia. In conclusion, xerostomia is closely associated to factors such as treatment for climacteric symptoms and certain menopausal symptoms, and it may be related to QOL in perimenopausal women.

Abstract
This study aimed to investigate the effects of various concentrations of cevimelines (CVMs) and compare them with commercial drugs in a murine model of dry eye. The experimental mouse model used male and female NOD.B10.H2b mice over 12 weeks of age. Desiccation stress was performed at 30-40% ambient humidity, and subcutaneous injection of 0.5 mg/0.2 mL scopolamine hydrobromide was performed four times a day for 10 days. The efficacy of various concentrations of CVMs (seven experimental groups) was first evaluated, and then 2% CVM was compared with commercial drugs, such as cyclosporine A (CsA), diquafosol (DQS), and rebamipide (REB) (seven experimental groups). The clinical changes, including tear production, corneal irregularity, and fluorescein staining, were measured after the instillation of various concentrations of CVMs and commercial drugs for 0, 3, 5, 7, and 10 days. Histological changes, such as corneal detachment, conjunctival goblet cell and mucin density staining, were assessed by staining the cornea or conjunctiva with hematoxylin-eosin, periodic acid-Schiff, and alcian blue. The expression of inflammatory markers and mucin factors was detected by immunohistochemistry and immunofluorescence in the lacrimal gland, cornea, and conjunctiva. Tear production was significantly increased in the 2% CVM group and was similar to that in the DQS and REB groups (P < 0.05). The corneal smoothness and fluorescein staining score were significantly improved in the 2% CVM group and were similar to those in the REB group (P < 0.05). Corneal epithelial cells were significantly decreased in the 2% CVM group, with similar observations made in the DQS and REB groups (P < 0.05). The conjunctival goblet cells and mucin density recovered in the 2% CVM group were similar to those in the CsA and REB groups (P < 0.05). The 2% CVM group showed suppressed expression of inflammatory factors in the lacrimal gland and was comparable to that seen in the CsA and REB groups. The expression of mucin factors was upregulated in the cornea and conjunctiva of the 2% CVM group and was similar to that of the CsA and REB groups. In conclusion, administration of CVM resulted in recovery or clinical and histological improvement of the murine dry eye model, and all the observed parameters were comparable to those with commercial drugs.

Abstract
The lacrimal gland is essential for lubrication and protection of the eye. Disruption of lacrimal fluid production, composition, or release results in dry eye, causing discomfort and damage to the ocular surface. Here, we describe the establishment of long-term 3D organoid culture conditions for mouse and human lacrimal gland. Organoids can be expanded over multiple months and recapitulate morphological and transcriptional features of lacrimal ducts. CRISPR-Cas9-mediated genome editing reveals the master regulator for eye development Pax6 to be required for differentiation of adult lacrimal gland cells. We address cellular heterogeneity of the lacrimal gland by providing a single-cell atlas of human lacrimal gland tissue and organoids. Finally, human lacrimal gland organoids phenocopy the process of tear secretion in response to neurotransmitters and can engraft and produce mature tear products upon orthotopic transplantation in mouse. Together, this study provides an experimental platform to study the (patho-)physiology of the lacrimal gland.

Abstract
γ-Butyrolactone, a five-membered lactone moiety, is one of the privileged structures of diverse natural products and biologically active small molecules. Because of their broad spectrum of biological and pharmacological activities, synthetic methods for γ-butyrolactones have received significant attention from synthetic and medicinal chemists for decades. Recently, new developments and improvements in traditional methods have been reported by considering synthetic efficiency, feasibility, and green chemistry. In this review, the pharmacological activities of natural and synthetic γ-butyrolactones are described, including their structures and bioassay methods. Mainly, we summarize recent advances, occurring during the past decade, in the construction of γ-butyrolactone classified based on the bond formation in γ-butyrolactone between (i) C5-O1 bond, (ii) C4-C5 and C2-O1 bonds, (iii) C3-C4 and C2-O1 bonds, (iv) C3-C4 and C5-O1 bonds, (v) C2-C3 and C2-O1 bonds, (vi) C3-C4 bond, and (vii) C2-O1 bond. In addition, the application to the total synthesis of natural products bearing γ-butyrolactone scaffolds is described.

Abstract
Sjögren’s syndrome (SS) is a chronic, progressive, inflammatory, autoimmune disease, characterized by the lymphocyte infiltration of exocrine glands, especially the lacrimal and salivary, with their consequent destruction. The onset of primary SS (pSS) may remain misunderstood for several years. It usually presents with different types of severity, e.g., dry eye and dry mouth symptoms, due to early involvement of the lacrimal and salivary glands, which may be associated with parotid enlargement and dry eye; keratoconjunctivitis sicca (KCS) is its most common ocular manifestation. It is still doubtful if the extent ocular surface manifestations are secondary to lacrimal or meibomian gland involvement or to the targeting of corneal and conjunctival autoantigens. SS is the most representative cause of aqueous deficient dry eye, and the primary role of the inflammatory process was evidenced. Recent scientific progress in understanding the numerous factors involved in the pathogenesis of pSS was registered, but the exact mechanisms involved still need to be clarified. The unquestionable role of both the innate and adaptive immune system, participating actively in the induction and evolution of the disease, was recognized. The ocular surface inflammation is a central mechanism in pSS leading to the decrease of lacrimal secretion and keratoconjunctival alterations. However, there are controversies about whether the ocular surface involvement is a direct autoimmune target or secondary to the inflammatory process in the lacrimal gland. In this review, we aimed to present actual knowledge relative to the pathogenesis of the pSS, considering the role of innate immunity, adaptive immunity, and genetics.

Abstract
Introduction Oral administration of pilocarpine enhances salivary flow in sicca patients but its effect upstream on ultrasound (US) of salivary glands (SG) and downstream on periodontium remain unknown.
Methods Sicca patients were prospectively included. Echostructural and vascularization of SG were assessed using B mode and pulsed Doppler (USPD). Vascularization of SG was measured using resistive index (RI) before and after stimulation by lemon juice. Echostructure (measure of glandular length in cm2, evaluation of parotid and submandibular glands parenchymal abnormalities) was assessed at baseline (M0) and after 3 months (M3) of treatment with pilocarpine. A dental consultation was performed at M0 and M3 to evaluate changes in unstimulated salivary flow (USSF), stimulated salivary flow (SSF), and periodontal parameters such as modified gingival index (Lobene), plaque index (Silness), bleeding index, pocket depth, and pH.
Results Nineteen patients were included but only 11 received pilocarpine treatment for 3 months, as six stopped pilocarpine due to side effects and two were excluded for other causes. Among the 11 patients who completed the 3-month follow-up, five had primary Sjögren’s syndrome according to the American-European’s classification criteria. As expected, statistical differences were found concerning SSF (p = 0.018) and USSF (p = 0.027) between M0 and M3 while no statistical change in both SG echostructure and vascularization or periodontal evaluation was shown. Conclusions Pilocarpine improved SSF and USSF measurements in sicca syndrome but no ultrasonography of major salivary glands (SGUS) structural and vascular changes were detected as well as periodontal evaluation.

Abstract
Dry eye symptoms can negatively affect the psychological, physical, and social functioning, which can potentially impair the health-related quality of life. This review evaluated the association between autoimmune related dry eye in the absence of significant ocular surface co-morbidities and mental health. This review found a significantly higher prevalence of mental health disorders (such as depression and anxiety) in systemic lupus erythematous, rheumatoid arthritis, systemic sclerosis, Behcet’s disease, and primary Sjogren’s syndrome patients when compared to the general population. Moreover, patients with depression and anxiety interpret ocular sensations differently than healthy controls and the perception of dry eye symptoms can be influenced by their mood. Somatization is common in depression, and this could influence the perception of ocular discomfort. Anti-depressants and anxiolytics with their potential side effects on the tear film status may also contribute or aggravate the dry eye symptoms in these patients. Although ophthalmologists manage the dry eye disease, as per standardized algorithms, they should be mindful of different ocular sensation interpretation and coexistent mental health issues in a large number of this patient group and initiate a multidisciplinary management plan in certain cases. While rheumatologists look after their autoimmune condition, it may be worth liaising with GP and/or psychiatrist colleagues in order to address their neuropathic type pain and mental health co-morbidities.

Abstract
Parasympathetic nervous system dysfunction is common in patients with liver disease. We have previously shown that muscarinic acetylcholine receptors (mAchRs) play an important role in the regulation of hepatic fibrosis and that the receptor agonists and antagonists affect hepatocyte proliferation. However, little is known about the impact of the different mAchR subtypes and associated signaling pathways on liver injury. Here, we treated the human liver cell line HL7702 with 10 mmol/L carbon tetrachloride (CCL4) to induce hepatocyte damage. We found that CCL4 treatment increased the protein levels of group I mAchRs (M1, M3, M5) but reduced the expression of group II mAchRs (M2, M4) and activated the Nrf2/ARE and MAPK signaling pathways. Although overexpression of M1, M3, or M5 led to hepatocyte damage with an intact Nrf2/ARE pathway, overexpression of M2 or M4 increased, and siRNA-mediated knockdown of either M2 or M4 decreased the protein levels of Nrf2 and its downstream target genes. Moreover, CCL4 treatment increased serum ALT levels more significantly, but only induced slight changes in the expression of mAchRs, NQO1 and HO1, while reducing the expression of M2 and M4 in liver tissues of Nrf2-/- mice compared to wild type mice. Our findings suggest that group II mAchRs, M2 and M4, activate the Nrf2/ARE signaling pathway, which regulates the expression of M2 and M4, to protect the liver from CCL4-induced injury.

Abstract
Sjögren's syndrome is a systemic autoimmune disease defined by its targeted inflammation of the salivary and lacrimal glands, resulting in dry mouth and eyes in the majority and persistent or recurrent salivary gland enlargement in a minority of those affected. Involvement of major organs, an increased risk of lymphoma, and autoantibodies against ubiquitous cellular ribonucleoproteins define some of its systemic features. Those affected have a high symptom burden and the development of disease-modifying therapies is thus an urgent need. A stratified medicine approach offers promise as a means of targeting specific therapies to patients for whom the mechanism of action is most relevant. Implementation of this approach will require an understanding of the pathophysiological processes underlying different patient subsets, and then identifying or developing a drug that targets this pathway. Such therapies would be most effective if implemented early in the disease course before the advent of adverse outcomes or glandular damage. This review will provide a disease overview followed by an analysis of the feasibility of a stratified medicine approach, focusing on the disease heterogeneity, predictors of disease progression and adverse outcomes, and recent advances in the development of relevant outcome measures and new therapies.

Abstract
Background Primary Sjögren’s syndrome (pSS) is associated with dental caries. Pilocarpine, a salivary stimulant, can improve the amount and flow rate of saliva in patients with pSS. This study aimed to assess whether the risk of dental caries decreases with the use of pilocarpine in patients with pSS. Methods For this prospective cohort study, we identified pSS patients from the catastrophic illnesses registry of the National Health Insurance Research Database of Taiwan between 2009 and 2013. We divided participants into pilocarpine and non-user groups based on the pilocarpine prescriptions available during the first 3-month follow-up. The primary endpoint was dental caries. The secondary endpoints were periodontitis and oral candidiasis. We compared the risk of these oral manifestations using the Cox proportional hazard model. Results A total of 4973 patients with new-onset pSS were eligible for analysis. After propensity score matching, we included 1014 patients in the pilocarpine group and 2028 patients in the non-user group. During the mean follow-up of 2.6 years, the number of events was 487 in the pilocarpine group (48.0%) and 1047 in the non-user group (51.6%); however, the difference was not significant (hazard ratio [HR] 0.93, 95% confidence interval [CI] 0.82 to 1.06). Furthermore, there was no significant difference between groups regarding risk of periodontitis (HR 0.91, 95% CI 0.81 to 1.03) and oral candidiasis (HR 1.16, 95% CI 0.70 to 1.94). Conclusion Pilocarpine may have no protective effect on dental caries, periodontitis, or oral candidiasis in patients with pSS.

Abstract
Systemic dry syndrome affects quality of life, and various effective methods are being developed for its treatment. We recently found that rooibos (Aspalathus linearis) extract activates muscarinic M3 receptor and improves dryness in mice and humans. We identified eriodictyol-6-C-β-D-glucoside (E6CG) as the active component affecting the secretory functions of exocrine glands; however, the pharmacokinetics and distribution of E6CG in exocrine glands have not been elucidated in mice receiving rooibos extract. We have developed a quantification method using LC-MS/MS to detect E6CG without an internal standard. Experiments on C57BL/6 mice administered rooibos extract showed that E6CG was transferred into blood plasma, with its concentration levels peaking 19.3 min after treatment. Substantial levels of E6CG were detected in the submandibular, sublingual, parotid, and lacrimal glands and in the sweat glands in palm skin. This study reports that rooibos extracts containing E6CG can be used as functional foods for improving systemic dryness.

Abstract
The prevalence of primary Sjögren's syndrome (pSS) is between 1:100 and 1:1000 and it is therefore the most common connective tissue disease. Nevertheless, it can be difficult to diagnose pSS as the symptoms are frequently unspecific and diagnostic markers are lacking in many patients. In addition, only few controlled therapeutic studies of pSS have been carried out so that the optimal management is not yet clear. Meanwhile, outcome parameters to monitor clinical improvement have been developed and a large number of therapeutic studies are currently being performed. This review article summarizes the current diagnostic and treatment options for pSS.

Abstract
Pilocarpine is an M3 muscarinic agonist that is widely used for the treatment of xerostomia caused by various diseases and medical conditions. Pilocarpine induced the secretion of salivary fluid in perfused submandibular glands of rats. The secretion of salivary fluid observed after removal of pilocarpine was referred to as residual fluid secretion. The volume of fluid and time of the residual secretion depended on the dose of pilocarpine. Such a residual effect of pilocarpine was observed on fluid secretion via the paracellular pathway and oxygen consumption. When a muscarinic antagonist was added to the perfusate immediately after cessation of pilocarpine, residual secretion of salivary fluid did not occur. These observations indicate that the residual secretion of salivary fluid is a characteristics of the interaction of pilocarpine with muscarinic receptors.

Abstract
BACKGROUND Xerostomia is caused by different factors such as side effects of medication, radiotherapy by head and neck cancer as well as Sjögren syndrome. AIM The goal was to synthesize novel preactivated chitosan conjugates and to design adhesive dosage forms comprising sialagogue pilocarpine. METHODS Unmodified chitosan (CH) was covalently linked to sulfhydryl possessing mercaptonicotinic acid (MNA) via amide bond formation. In a second step, preactivation occurred via disulfide bond establishment between sulfhydryl linked chitosan and preactivation ligand MNA. Mucoadhesive and mucoprotective properties were scrutinized on buccal mucosa. Safety assessment was performed on head and neck squamous cells. Histology assay was conducted on buccal tissue. Pilocarpine was scrutinized in terms of controlled release behavior. RESULTS Novel preactivated CH was successfully synthesized and considered as not harmful to the cells at all. Furthermore, mucoadhesion was 1.3-fold improved in the presence of preactivated chitosan as compared to respective unmodified one. Pilocarpine exhibited a 3.1-fold controlled release in presence of novel synthesized chitosan as in comparison to unmodified CH. CONCLUSION The novelty of this promising polymeric carrier lies in the synthesis procedure leading to a pronounced mucoadhesive, mucoprotecting and controlled release encouraging dosage form in the management of xerostomia.

Abstract
In primary SS (pSS), clinical features in SS can be divided into two facets: the patient perceived manifestations such as dryness, pain and fatigue, and the systemic manifestations. In the past decades, with efforts made by an international collaboration, consensual clinical indexes were developed for assessing both facets: one patient reported outcome, the EULAR SS Patients Reported Index (ESSPRI), and one activity index for systemic manifestations, the EULAR SS Disease Activity Index (ESSDAI). In addition, objective measures were developed to quantify the importance and consequence of ocular and oral dryness, few being specific of pSS. Work is ongoing to develop indexes combining all these approaches. Recent changes in the assessment of pSS patients, and the emergence of new targeted therapies, have put a greater emphasis on the design of clinical trials in pSS, and led for the first time to a positive randomized clinical trial.

Abstract
Sjögren's syndrome (SS) is a systemic orphan disease. It is characterized by the involvement of epithelial tissues leading to the term of autoimmune epithelitis. New classification criteria have been developed in 2016. New scores have also been developed: a patient-reported outcome called ESSPRI and a score assessing systemic activity of the disease called ESSDAI. These new tools are very helpful to better stratify patients and to customize the management of this very heterogeneous disease. Among the autoimmune diseases, SS is associated with the highest risk of lymphoma. Five to ten percent of the patients will have a B cell lymphoma mostly a low-grade lymphoma developing from mucosa-associated lymphoid tissue (MALT). Major advances have been made in this field: pathogeny is better understood, new predictors are available and progresses have been made in the management of this severe complication. Research in the field of SS is very dynamic as illustrated by the high number of therapeutic trials. There is hope that these innovations, reviewed in the present article, will have potential significant repercussions for the patients in the next few years.

Abstract
Introduction: Sjogren's syndrome is an immunologic disorder, characterized by symptoms of dry mouth and dry eyes. Management of xerostomia is more difficult and challenging, various pharmacologic agents have been tried and evaluated in the management of xerostomia in these patients, but the results were inconsistent and variable. Hence, the present study is aimed at evaluation and comparison of different pharmacological agents in the management of xerostomia in patients with Sjogren's syndrome. Materials and methods: A meta-analysis of case-control studies was conducted on pharmacological management of xerostomia in patients with Sjogren's Syndrome and the collected data are subjected to exclusion and inclusion criteria and standard mean difference (SMD), ODD's ratio and confidence intervals (95% CI) were calculated by Review Manager software using fixed and random effects model from the data of five studies. Results: Both objective response and subjective response evaluation favored experimental group suggesting an increase in unstimulated salivary flow rate using pharmacological agents. Interferon alpha 150 IU three times daily had a good effect in increasing the unstimulated whole saliva flow rate with SMD 2.72 at 95% CI [2.43, 3.00] p < .00001. Cevimeline vs placebo showed good response with ODDS ratio 2.74 at 95% CI [1.58, 4.76] p = .0003. Conclusion: Interferon - α 150 IU thrice daily was proven to be effective in increasing salivary flow rate and also has an advantage of disease modification in SS patients attributing to its immunomodulatory action. Cevimeline 30 mg thrice daily also had a considerable therapeutic effect in SS patients compared to Pilocarpine.
