Prevalence of Sjögren's syndrome in patients with dry mouth in the region of Central Hungary.

OBJECTIVE: One-third of the Hungarian population suffers from xerostomia. Since there is no evidence of the actual prevalence of Sjögren's syndrome (SS) in Hungary, this study aimed to evaluate the same. MATERIALS AND METHODS: Data were collected from the Faculty of Dentistry, Semmelweis University from 2008 to 2015. A diagnosis of SS was established based on the American College of Rheumatology and European League Against Rheumatism criteria. RESULTS: Of the 1076 patients examined with sicca symptoms, 188 patients had confirmed SS. Primary SS (pSS) was diagnosed in 135 patients and secondary SS (sSS) was confirmed in 53 patients. According to the available statistical records of the public health service of Hungary, there were an average of 16 (0.0014%, 5-26) newly diagnosed SS cases in the entire population and 141 SS patient-practitioner consultations (49-232) per 100,000 inhabitants in the country over the past 10 years (based on the past 10 years: 2011-2020). CONCLUSION: Results revealed that approximately 1/5th-1/6th of patients with sicca symptoms have SS, among whom 72% and 285 have pSS and sSS, respectively. Global Hungarian records simultaneously revealed that the number of both new diagnoses and doctor-SS patient encounters has significantly decreased (by 50%) yearly over the last decade.

Standardisation of ACPA tests: evaluation of a new candidate reference preparation.

INTRODUCTION: Commercial assays measuring antibodies to citrullinated protein/peptide (ACPA) show poor quantitative agreement. The diagnostic industry has never adopted the International Union of Immunological Societies-Centers for Disease Control and Prevention (IUIS-CDC) ACPA reference standard. Recently, the National Institute for Biological Standards and Control (NIBSC) prepared a new candidate ACPA standard (18/204). We evaluated both reference materials using different commercially available ACPA assays. MATERIALS AND METHODS: This is an international study in which the NIBSC candidate ACPA standard and the IUIS-CDC ACPA reference material were analysed together with 398 diagnostic samples from individuals with rheumatoid arthritis (RA) and in 1073 individuals who did not have RA using nine commercial ACPA assays. RESULTS: For both reference materials and samples from individuals with RA and individuals who did not have RA, there were large differences in quantitative ACPA results between assays. For most assays, values for the IUIS-CDC standard were lower than values for NIBSC 18/204 and the IUIS-CDC/NIBSC ratio was comparable for several, but not all assays. When NIBSC 18/204 was used as a calibrator, an improvement in alignment of ACPA results across several of the evaluated assays was obtained. Moreover, NIBSC 18/204 could align clinical interpretation for some but not all assays. CONCLUSION: Adoption of an international standard for ACPA determination is highly desirable. The candidate NIBSC 18/204 standard improved the standardisation and alignment of most ACPA assays and might therefore be recommended to be used as reference in commercial assays.

IgA rheumatoid factor in rheumatoid arthritis.

OBJECTIVES: Rheumatoid factor (RF) is a well-established marker for the diagnosis and classification of rheumatoid arthritis (RA). Most studies evaluated IgM RF or isotype-nonspecific total RF assays. We evaluated the added value of IgA RF in this context. METHODS: An international sample cohort consisting of samples from 398 RA patients and 1073 controls was tested for IgA RF with 3 commercial assays. For all RA patients and 100 controls essential clinical and serological data for ACR/EULAR classification were available. RESULTS: The sensitivity of IgA RF for diagnosing RA was lower than the sensitivity of IgM RF. Differences in numerical values between IgA RF assays were observed. With all assays, the highest IgA RF values were found in patients with primary Sjögren's syndrome. Double positivity for IgM RF and IgA RF had a higher specificity for RA than either IgM RF or IgA RF. The sensitivity of double positivity was lower than the sensitivity of either IgA RF or IgM RF. Single positivity for IgA RF was at least as prevalent in controls than in RA patients. Adding IgA RF to IgM RF and anti-citrullinated protein antibodies (ACPA) did not affect RA classification. However, combined positivity for IgA RF, IgM RF and IgG ACPA had a higher specificity and lower sensitivity for RA classification than positivity for either of the antibodies. CONCLUSIONS: IgA RF showed a lower sensitivity than IgM RF. Combining IgA RF with IgM RF and ACPA did not improve sensitivity of RA classification. Combined positivity (IgA-RF/IgM-RF/ACPA) increased specificity.

Glucocorticoid receptor polymorphisms in rheumatoid arthritis: results from a single centre.

OBJECTIVES: Until now, glucocorticoids (GCs) with their anti-inflammatory and immune suppressive effects are one of the most effective agents in therapy of several autoimmune disorders including rheumatoid arthritis (RA). Glucocorticoid receptor (GR) polymorphisms may result in variable sensitivity to glucocorticoids playing an important role in the development and control of symptoms in RA. We aimed to test whether the functional polymorphisms of the GR encoding gene (NR3C1) are associated with susceptibility to RA and with various clinical signs and symptoms. METHODS: 146 patients were enrolled at the National Institute of Reumatology. Clinical diagnosis was based on the criteria of the American College of Rheumatism (ACR) 2010. Complex clinical, routine laboratory and immunlaboratory evaluations were performed. For genotyping of the GR polymorphisms N363S (rs6195), BclI (rs41423247) and 9ß (rs6198) peripheral blood DNA was used, extracted with commercially available reagents. Genotyping was performed with routine molecular biological methods. Genetic data were compared to those obtained in a healthy control group (n=160) using Chi square or Fisher tests. Associations between GR genotypes and clinical and immunological parameters were determined with ANOVA. RESULTS: The main finding of the present study is the lower frequency of the BclI in RA patients. Furthermore, regarding the laboratory and immunoserological parameters, the level of anti-DNA antibody was significantly higher in homozygous BclI carriers compared to heterozygous carriers, irrespective of the anti-TNF-alpha therapy. CONCLUSIONS: Our results reveal that although GR polymorphisms are not key players in development or clinical course of RA, they might affect glucocorticoid action and, together with other endogenous and exogenous factors, interfere with the pathomechanism of RA. Our results reveal some possible factors (including BclI polymorphism), and therefore contribute to elucidate the implication of the combination of GR functional variants.

Genetic Polymorphism of GSTP-1 Affects Cyclophosphamide Treatment of Autoimmune Diseases.

Cyclophosphamide is one of the most potent and reliable anti-cancer and immunosuppressive drugs. In our study, 33 individuals with different autoimmune diseases were treated with cyclophosphamide according to standard protocols. The responses to the treatments were determined by measuring the alteration of several typical parameters characterizing the given autoimmune diseases over time. We concluded that about 45% of the patients responded to the treatment. Patients were genotyped for polymorphisms of the CYP3A4, CYP2B6, GSTM1, GSTT1, and GSTP1 genes and disease remission cases were compared to the individual polymorphic genotypes. It was found that the GSTP1 I105V allelic variation significantly associated with the cyclophosphamide treatment-dependent disease-remissions. At the same time the GSH content of the erythrocytes in the patients with I105V allelic variation did not change. It appears that the individuals carrying the Ile105Val SNP in at least one copy had a significantly higher response rate to the treatment. Since this variant of GSTP1 can be characterized by lower conjugation capacity that results in an elongated and higher therapeutic dose of cyclophosphamide, our data suggest that the decreased activity of this variant of GSTP1 can be in the background of the more effective disease treatment.

The Hungarian version of the Juvenile Arthritis Multidimensional Assessment Report (JAMAR).

The Juvenile Arthritis Multidimensional Assessment Report (JAMAR) is a new parent/patient-reported outcome measure that enables a thorough assessment of the disease status in children with juvenile idiopathic arthritis (JIA). We report the results of the cross-cultural adaptation and validation of the parent and patient versions of the JAMAR in the Hungarian language. The reading comprehension of the questionnaire was tested in 10 JIA parents and patients. Each participating centre was asked to collect demographic, clinical data and the JAMAR in 100 consecutive JIA patients or all consecutive patients seen in a 6-month period and to administer the JAMAR to 100 healthy children and their parents. The statistical validation phase explored descriptive statistics and the psychometric issues of the JAMAR: the three Likert assumptions, floor/ceiling effects, internal consistency, Cronbach's alpha, interscale correlations, test-retest reliability, and construct validity (convergent and discriminant validity). A total of 206 JIA patients (3.9% systemic, 41.3% oligoarticular, 28.2% RF-negative polyarthritis, 26.6% other categories) and 90 healthy children, were enrolled in two centres. The JAMAR components discriminated healthy subjects from JIA patients. All JAMAR components revealed good psychometric performances. In conclusion, the Hungarian version of the JAMAR is a valid tool for the assessment of children with JIA and is suitable for use both in routine clinical practice and clinical research.

[Extraadrenal glucocorticoid synthesis]. / Extraadrenalis glükokortikoidszintézis.

Endogenous glucocorticoids exert a diverse array of physiological processes and play an important role in immune modulatory and anti-inflammatory responses. The secretion of cortisol by the adrenal gland is regulated through two mechanisms. Systemic regulation is substantiating by the hypothalamo-pituitary-adrenal axis. Furthermore, a tissue-specific local regulatory system, containing the 11ß-hydroxysteroid dehydrogenase enzyme responsible for local glucocorticoid synthesis and the glucocorticoid receptor, has also been demonstrated. Based on the recent evidences, an extra-adrenal corticosteroid synthesis exists in various tissues. Steroidogenic enzymes necessary for this de novo corticosteroid synthesis have been observed in the skin, intestine, thymus and possibly in the brain, heart and lung. These locally synthesized steroids most likely act in an autocrine and paracrine manner and their regulation is mediated by local regulatory loops. The importance of this de novo corticosteroid synthesis seems to be important in the regulation of local homeostasis, immune processes and tissue-specific inflammatory reactions.

Coronary Artery Manifestation of Ormond Disease: The "Mistletoe Sign".

A 69-year-old woman presented with symptoms of presumed cardiac involvement of idiopathic retroperitoneal fibrosis, otherwise known as Ormond disease. Distinct pericoronary tissue proliferations were depicted at cardiac magnetic resonance (MR) imaging and coronary computed tomographic (CT) angiography. On images, the coronary manifestation was termed the "mistletoe sign." The presence of the mistletoe sign on cardiac MR and coronary CT angiographic images is probably rare, but it might be a characteristic manifestation of retroperitoneal fibrosis. With the increasing number of noninvasive cardiac imaging tests performed worldwide, the recognition of the mistletoe sign could be helpful in diagnosing retroperitoneal fibrosis. © RSNA, 2016 Online supplemental material is available for this article.

[Recent advances in the treatment of large vessel vasculitides]. / Nagyérvasculitisek korszeru kezelése.

Giant cell arteritis and Takayasu arteritis classified to large vessel vasculitides have similar histopathology in the vascular wall proposing that these entities can be different phenotypes on a spectrum of a single disorder. Glucocorticoids are the mainstay of therapy combined with cyclophosphamide, azatioprine and mycofenolate mofetil, when it is required. However, a significant proportion of patients are glucocorticoid-dependent despite of the conventional disease-modifying antirheumatic drugs and suffer from serious side effects of the steroids, therefore alternate options for more effective disease management are needed. The article reviews the advances in the treatment of large vessel vasculitides. Tumor necrosis factor-alpha inhibitors seem to be effective in Takayasu arteritis, but have a little benefit in giant cell arteritis. Interleukin-6 inhibitor appears very promising in both refractory giant cell arteritis and Takayasu arteritis as well. Abatacept and ustekinumab also seem to be a good choice for the therapy. Orv. Hetil., 2017, 158(1), 5-12.

[Clinical guideline for the treatment of lupus nephritis and single-centre results of mycofenolate mofetil among patients with lupus nephritis in the National Institute of Rheumatology and Physiotherapy, Budapest]. / A lupus nephritis kezelésének irányelvei, valamint a mycofenolat mofetil hatékonyságának bemutatása intézetünk lupus nephritises betegeinek körében.

The authors present the latest guideline for the treatment of lupus nephritis and their own single-centre results with mycofenolate mofetil treated lupus nephritis. Lupus nephritis and mainly its proliferative form is a frequent and potentially life-threatening manifestation of systemic lupus erythematosus that can lead to end-stage renal disease. The treatment of lupus nephritis greatly improved in the last decades; mycofenolate mofetil has become an alternative of cyclophosphamide both in remission induction and as a maintenance regimen as well in the treatment of Class III and IV glomerulonephritis. The authors ordered mycofenolate mofetil for 25 patients with lupus nephritis so far. Histologically most of them had Class III (A/C) or IV (A) glomerulonephritis (30-30%), and only 16% of the patients had renal impairment at that time. Mycofenolate mofetil given after glucocorticoid and cyclophosphamide induction therapy reduced the daily proteinuria from 3.18 grs to 1.06 grs. Complete remission could be achieved in 24% and partial remission in 48% of the patients. The authors conclude that mycofenolate mofetil is effective in the therapy of lupus nephritis. Orv. Hetil., 2016, 157(35), 1385-1393.

Systemic Autoimmune, Rheumatic Diseases and Coinciding Psoriasis: Data from a Large Single-Centre Registry and Review of the Literature.

Psoriasis is a systemic immune-inflammatory disease characterized by chronic or recurrent skin symptoms, psoriatic arthritis, enthesopathy, and uveitis. Psoriasis has recently been published to appear with various autoimmune disorders, but the coexistence has been systematically reviewed by only few studies until now. In the present study, charts and electronic database of 4344 patients with various systemic autoimmune disorders, under regular medical control at our department, were reviewed retrospectively searching for association with psoriasis. Hereby, we demonstrate 25 psoriatic patients coinciding with various systemic autoimmune diseases. The coexistence of psoriasis and autoimmune diseases resulted in the worsening of the clinical outcome of the autoimmune diseases as indicated by higher frequency and dosages of glucocorticoid use, need for biologicals, and other comorbidities. These results suggest common environmental and genetic background as well as therapeutic possibilities in the future.

[Recent advances in the treatment of antineutrophil cytoplasm antibody associated vasculitides]. / Antineutrofil citoplazmatikus antitest asszociált vasculitisek korszeru kezelése.

The authors review the nomenclature of vasculitides and the classification of antineutrophil cytoplasm antibody associated vasculitides and present the method of measuring disease activity (Five-factor Score, Birmingham Vasculitis Activity Score) and its role in defining therapeutical needs. They discuss the treatment algorithm of antineutrophil cytoplasm antibody associated vasculitides, present the sometimes equipotential medications used during the induction therapy followed by a maintenance regimen, and outline their usage and possible side-effects that may require medical attention. They point out the importance of plasmapheresis as an adjunctive treatment in some cases, as well as indications and possible outcome of kidney transplantation in therapy-resistant cases. Finally, they review several ongoing clinical studies, as their outcome will probably influence therapeutical opportunities of antineutrophil cytoplasm antibody associated vasculitides in the next few years.

In-/off-label use of biologic therapy in systemic lupus erythematosus.

Current therapies for systemic lupus erythematosus (SLE) include corticosteroids as a persistent mainstay and traditional immunosuppressants which are given according to disease severity, organ involvement and patient status. No treatment entails certain efficacy devoid of mild-to-moderate adverse effects. Nowadays, novel therapies are being developed aiming to target specific molecules involved in SLE development and progression which show variable effectiveness and safety. Biologic agents considered for SLE comprise monoclonal antibodies (chimeric, humanized or fully human) as well as fusion molecules or antibody fragments mostly consisting of B cell-targeted therapies beside anti-cytokines as well as T cell-targeted therapies. Encouraging evidence on biologics is mostly provided by case series or uncontrolled studies; conversely, larger randomized controlled clinical trials have frequently missed their primary endpoints with the exception of BLISS-52 and BLISS-76 trials. Actually, apart from belimumab, biologics are employed in clinical practice as off-label treatments for lupus and results are often promising, depending on specific SLE features, dose regimens and individual responsiveness.

Complement receptor type 1 (CR1, CD35) is a potent inhibitor of B-cell functions in rheumatoid arthritis patients.

The involvement of B cells, complement activation and subsequent immune complex deposition has all been implicated in the pathogenesis of rheumatoid arthritis (RA). Although the reduced expression of complement receptor 1 (CR1, CD35) and 2 (CR2, CD21) on the B cells of RA patients has been known for a long time, their exact role in B-cell tolerance and autoimmunity is not yet fully understood. To get a deeper insight into the possible mechanisms, we studied the expression and function of CR1 and CR2 on various subsets of B cells of healthy donors and RA patients at various stages of the disease by FACS analysis, (3)H-thymidine incorporation and ELISA. We found that CD19(+)CD27(-) naive B cells up-regulate the expression of the inhibitory CR1 during differentiation to CD19(+)CD27(+) memory B cells both in healthy donors and in RA patients, whereas the expression of the activatory CR2 is down-regulated. This clearly demonstrates that the expression of these two antagonistic complement receptors is regulated differentially during the development of human B cells, a phenomenon which may influence the maintenance of peripheral B-cell tolerance. Our functional studies show that after clustering CR1 both by its natural ligand and To5 mAb, the inhibitory function of CD35 is maintained in RA patients, despite its significantly reduced expression compared with healthy individuals. Besides blocking B-cell receptor-induced proliferation, CR1 inhibits the differentiation of B cells to plasmablasts and their immunoglobulin production. Since the reduced expression of CR1 in RA patients does not affect its inhibitory function, this receptor might serve as a new target for therapeutical interventions.

Oral Mucosal Human Papillomavirus and Epstein-Bar Virus Rates in Patients with Dry Mouth and/or Sjögren's Syndrome in a Hungarian Cohort.

PURPOSE: To find an association between oral mucosal human papilloma- and/or Epstein-Barr (HPV, EBV) virus infection in patients with dry mouth and/or Sjögren's syndrome (SS) compared to healthy controls and to find connections with salivary gland histopathological alterations. MATERIALS AND METHODS: Ninety-two participants were divided into four groups: 1. healthy controls (n = 32); 2. xerostomia (n = 28); 3. hyposalivation (n = 22); and 4. SS groups (n = 10). To detect virus infection brush biopsy was outlined in all groups. Detections of virus-specific sequences were achieved with polymerase chain reaction (PCR). Lip biopsy and histopathological assessment was performed in groups 2, 3 and 4. RESULTS: HPV positivity of oral mucosal cells was shown in group 1: 1 (3.12%); group 2: 3 (10.7%); group 3: 2 (8.26%); and in group 4: 0 of the samples. EBV was present in group 1: 14 (43.7%); group 2: 17 (60.7%); group 3: 6 (27.3%); and in group 4: 5 (50%) of the cases. There was no statistically significant difference between the attributes. Intact salivary gland in 28.2%, chronic sialadenitis in 28.2%, stromal fibrosis in 6.5%, lipomatous atrophy in 8.6%, fibrous atrophy in 6.5% and positive focus score (SS) in 26.1% were found in the subjects. Neither HPV nor EBV infection caused statistically significantly more histological abnormalities. CONCLUSION: Orofacial mucosal HPV and/or EBV DNA rates did not differ statistically significantly in patients with xerostomia or hyposalivation or SS compared to healthy controls, therefore, it cannot prove the provocative role of these viruses in dry mouth and/or SS. Neither dry mouth nor SS were accompanied by statistically significantly more salivary gland alterations in HPV- and/or EBV-positive subjects; these alterations are frequent in the virus-negative cases too.

Psychosocial, educational, and somatic factors in chronic nonspecific low back pain.

Analysis of the effect of psychosocial factors and co-morbidities on the health status of patients with chronic nonspecific low back pain and patients with surgical intervention because of disk herniation was performed. One hundred and two nonselected consecutive inpatients with chronic nonspecific low back pain were included in the study. Their average age was 56.7 (SD = 10.9) years. The control group consisted of 199 subjects matched according to age and sex, chosen from the database of the national representative health survey Hungarostudy 2006, which involved 4,527 subjects. We measured quality of life including mental health with the SF-36 questionnaire validated for use in Hungary, the short 9-item version of the Beck Depression Inventory, the WHO-Five Well-Being Index, and the Hospital Anxiety-Depression Scale. We characterized the socio-demographic status with variables on age, sex, marital status, and education. Data on symptoms and signs of low back pain, other musculoskeletal diseases, and their treatments including spinal surgery were recorded. Co-morbidity and body mass index were considered as independent indicators of health. Depression as measured by Beck Depression Inventory and severity of depression did not vary significantly according to marital status, education, hypertension, diabetes, and gastrointestinal disease. Only half of the patients (52 %) were in the normal range of the scale; 22 % suffered from mild, 16 % from moderate, and 12 % from severe depression. Average values for anxiety and depression as measured by Hospital Anxiety-Depression Scale and Beck Depression Inventory were both significantly higher in the patient than in the control group (Hospital Anxiety Scale: p = 0.0001; Beck Depression Inventory: p = 0.0001). According to the WHO Well-Being Index-5 scale, the difference between patients and the control group was significant (p = 0.0001). Furthermore, correlation was found between the incidence of depression and surgery. Depression was demonstrated in 47.4 % of those patients who had no surgery, in 50 % of patients who had one round of surgery, and in 62.5 % of those who had undergone surgery more than once; the contingence coefficient was 0.211. According to different measurements, the psychological state of patients with chronic nonspecific low back pain was significantly altered as compared to the matched Hungarian population. Higher anxiety and depression markers occurred in 48 % of the patients. There was no correlation between the depression of patients with low back pain and variables such as marital status, education, and co-morbidities. Our study is the first to demonstrate that depression runs parallel with the number of surgical procedures. Therefore, if there is a relative indication for surgery, depression and severity of depression should be assessed and considered when deciding on the intervention.

[Behcet's disease: a rarely recognized orphan disorder]. / Egy ritkán felismert ritka betegség: a Behcet-kór.

Behcet's disease is a multisystem autoimmune disease with variable clinial manifestations. The diagnosis may pose a difficult challenge for the clinician, who has to be familiar with the wide spectrum and combination of the symptoms of Behcet's disease. It is considered a rare disease in Hungary, and there are only few reports on Behcet's disease in the Hungarian literature. However, the past history of Hungary, the worldwide growing incidence of the disease, and the authors' experience raise the possibility that the occurrence of the disease is higher than previously thought. In this review the authors present and discuss literature data on the pathogenesis and pathomechanism, as well as their own experience concerning the symptomatology of Behcet's disease in order to promote diagnosis and offer adequate therapy for the patients. The authors presume that the importance of the disease is underestimated in Hungary due to a considerable number of unrecognized cases and they propose to establish a national registry for Behcets disease.

[The stiff-person syndrome: a brief review and report of two cases]. / A stiff-person-szindrómáról két eset kapcsán.

The stiff-person syndrome is a rare and progressive neuromuscular disease which appears to have an immunpathological basis. It is characterised by painful muscle spasms and stiffness in the proximal muscles, especially those attached to the axial skeleton. The precise pathophysiology is still unknown, but several antibodies have been shown to be present in patients and these antibodies are directed against proteins which play a role in the inhibitor synapse linked to gamma-amino-butyrate. In the first part of the article the authors present two cases. In the second part they present a comprehensive review of our current knowledge about this rare disease.

[Successful completed pregnancies in patients with systemic lupus erythematosus]. / Sikeresen kiviselt terhességek jellemzése szisztémás lupus erythematosusban.

UNLABELLED: Systemic lupus erythematosus is a chronic autoimmune disorder which affects women with child bearing potential. AIM: The aim of this study was to investigate the successful pregnancies in patients with lupus in the past 10 years. Women were followed up at the 3rd Department of Internal Medicine, University of Debrecen. RESULTS: During this investigated period, 26 patients became pregnant. Seven patients had a positive history for lupus before the pregnancy. A total of 29 children were born. The mean gestational age was 35 weeks. The average birth weight was 2415 grams. Toxemic pregnancy was the most common complication found in 9 patients. Lupus nephritis activity occurred in 2 patients, and 1 of them had it for the first time during the course of her disease. CONCLUSIONS: In the past years, the number of pregnancies in patients with lupus has been increasing. Due to proper patient care and education, the outcome is more favourable.

Clinical Predictors of Lung-Function Decline in Systemic-Sclerosis-Associated Interstitial Lung Disease Patients with Normal Spirometry.

Interstitial lung disease (ILD) is the leading cause of mortality in systemic sclerosis (SSc). Progressive pulmonary fibrosis (PPF) is defined as progression in 2 domains including clinical, radiological or lung-function parameters. Our aim was to assess predictors of functional decline in SSc-ILD patients and compare disease behavior to that in idiopathic pulmonary fibrosis (IPF) patients. Patients with normal forced vital capacity (FVC > 80% predicted; SSc-ILD: n = 31; IPF: n = 53) were followed for at least 1 year. Predictors of functional decline including clinical symptoms, comorbidities, lung-function values, high-resolution CT pattern, and treatment data were analyzed. SSc-ILD patents were significantly younger (59.8 ± 13.1) and more often women (93 %) than IPF patients. The median yearly FVC decline was similar in both groups (SSc-ILD = −67.5 and IPF = −65.3 mL/year). A total of 11 SSc-ILD patients met the PPF criteria for functional deterioration, presenting an FVC decline of −153.9 mL/year. Cough and pulmonary hypertension were significant prognostic factors for SSc-ILD functional progression. SSc-ILD patients with normal initial spirometry presenting with cough and PH are at higher risk for showing progressive functional decline.
