Life (Basel) 2023; 13:life13020416. [PMID: 36836775 PMCID: PMC9962158 DOI: 10.3390/life13020416] [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: 11/27/2022] [Revised: 01/30/2023] [Accepted: 01/31/2023] [Indexed: 02/05/2023] Open
Abstract
Interstitial lung disease (ILD) has been recognized as an extrahepatic manifestation ofprimary biliary cholangitis (PBC), althoughlimited data are available on its prevalence and clinical significance. Therefore, we evaluated the occurrence and clinical features of ILD in a cohort of PBC patients. Ninety-three individuals without concomitant rheumatic diseases were enrolled in our prospective cohort study. All patients underwent chest high-resolution computed tomography (HRCT). Liver-related and lung-related survival wereassessed. A lung-related outcome was defined as death from ILD complications; a liver-related outcome was defined as liver transplantation or death from liver cirrhosis complications. HRCT findings suggestive ofILD were detected in 38 patients (40.9%). A sarcoid-like pattern of PBC-associated ILD was the most frequent, followed by subclinical ILD and organizing pneumonia. Patients with ILD were less likely to have liver cirrhosis and liver-related symptoms and presented with higher serum immunoglobulin M(IgM) and M2 subtype antimitochondrial antibodies (AMA-M2) positivity rates. In a multivariate analysis, the absence of liver disease symptoms at the disease presentation (OR 11.509; 95% CI 1.210-109.421; p = 0.033), the presence of hepatic non-necrotizing epithelioid cell granulomas (OR 17.754; 95% CI 1.805-174.631; p = 0.014), higher serum IgM (OR 1.535; 95% CI 1.067-2.208; p = 0.020) and higher blood leukocyte count (OR 2.356; 95% CI 1.170-4.747; p = 0.016) were independent risk factors associated with ILD in PBC. More than a third of patients with ILD showed no respiratory symptoms, and only one ILD-related death occurred during a follow-up of 29.0 months (IQR 11.5; 38.0). Patients with ILD had better liver transplant-free survival.ILD in PBC had a benign course and was associated with a lower liver disease severity. PBC-associated ILD should be included in a list of differential diagnoses of ILD.

Abstract
The most important autoimmune liver disease include: autoimmune hepatitis, primary biliary cholangitis and primary sclerosing cholangitis. In general, about one in three patients with an autoimmune liver disease have a concomitant extrahepatic autoimmune disease, which may include rheumatological, endocrinological, gastrointestinal, pulmonary or dermatological conditions. The pathogenesis of these conditions includes the production of both innate and adaptive immune responses targeting cholangiocytes as well as different extrahepatic tissues. In this sense, extrahepatic autoimmunity represent a continuous spectrum of autoimmunity involving liver and extrahepatic tissues. This review aims to focus the clinical and pathophysiological aspects of extrahepatic autoimmunity associated to autoimmune liver diseases.

Abstract
Patients with PBC have at least 60% of probability to have an autoimmune extrahepatic condition. The pathogenesis of these conditions includes a common mechanism involving both innate and adaptive immune responses targeting cholangiocytes and different extrahepatic tissues. The recent EASL guidelines recommend the management of these conditions, although detailed practical treatments have not been indicated. Autoimmune extrahepatic conditions may include: rheumatologic, endocrine, pulmonary, gastrointestinal, dermatologic diseases. This review aims to focus the most important extrahepatic autoimmune conditions associated to PBC with practical recommendation regarding diagnostic approach and management.

Abstract
Primary biliary cirrhosis (PBC) is a chronic progressive cholestatic liver disease caused by diffuse inflammation, destruction and fibrosis of the intrahepatic bile ducts, ultimately leading to cirrhosis, portal hypertension and liver failure. The pathogenesis of PBC is incompletely understood, but current data suggest roles for genetic susceptibility and environmental factors. PBC is often thought of as an organ-specific autoimmune disease, which mainly targets the liver; however, lung tissue is also a site for autoimmune involvement of PBC. The pulmonary manifestations of PBC include abnormalities in gas transfer and pulmonary function, subclinical alveolitis, interstitial lung disease, granulomatous lung disease, airway disease, pulmonary hypertension, pulmonary hemorrhage and pleural effusion.

Abstract
This review is devoted to the distinct associations of inflammatory bowel diseases (IBD) and chronic liver disorders with chronic airway diseases, namely chronic obstructive pulmonary disease and bronchial asthma, and other chronic respiratory disorders in the adult population. While there is strong evidence for the association of chronic airway diseases with IBD, the data are much weaker for the interplay between lung and liver multimorbidities. The association of IBD, encompassing Crohn's disease and ulcerative colitis, with pulmonary disorders is underlined by their heterogeneous respiratory manifestations and impact on chronic airway diseases. The potential relationship between the two most prevalent liver-induced pulmonary vascular entities, i.e. portopulmonary hypertension and hepatopulmonary syndrome, and also between liver disease and other chronic respiratory diseases is also approached. Abnormal lung function tests in liver diseases are described and the role of increased serum bilirubin levels on chronic respiratory problems are considered.

Abstract
A 47-year-old male was admitted with subacute onset of dry cough and fever. Chest tomography demonstrated multifocal areas of consolidation and ground glass attenuation. Cytological analysis of bronchoalveolar lavage revealed lymphocytosis and eosinophilia and anatomopathological exam of transbronchial cryobiopsy showed poorly formed non-caseous granulomas associated to interstitial lympho-plasmocitary infiltrate. The diagnosis of idiopathic granulomatous lung disease (GLD) was assumed and the patient started oral prednisolone, presenting clinical, functional and radiological improvement. Two years later, the patient was diagnosed with primary biliary cirrhosis (PBC). At this time, it was possible to associate GLD with the autoimmune hepatobiliary disease. Clinical, epidemiological and pathological aspects of this uncommon case of interstitial lung disease as first presentation of PBC in a male patient are discussed.

Abstract
Lung complications may occur as a result of hepatic disease from any cause and represent a highly heterogeneous group of conditions. Early recognition of such complications may be challenging but is crucial both in forming a meaningful differential diagnosis and in avoiding severe sequelae and irreversible damage. Although a number of different pathogenetic mechanisms are likely to be involved, chronic liver dysfunction may cause pulmonary manifestations because of alterations in the production or clearance of circulating cytokines and other mediators. This is likely to be the case in hepatopulmonary syndrome, portopulmonary hypertension and primary biliary cirrhosis, although their pathogenesis remains largely speculative. Moreover, the severity of lung manifestations may or may not correspond to that of liver impairment, making disease outcome often unpredictable. Congenital and inflammatory disorders, however, may primarily affect both the liver and lung. Apart from specific diseases, a number of medications can also result in pulmonary and hepatic toxic effects. This is particularly important with cytokine therapy - used to treat viral hepatitis, among other diseases - because treatment consists of drug discontinuation, which, in turn, may cause reactivation or progression of the underlying disease that the drug was used for. This review summarizes salient diagnostic and therapeutic aspects of these often misdiagnosed conditions and highlights, based on the most recent literature, the need for early referral of such patients to centres with specific expertise in the field. In fact, a multidisciplinary approach involving pulmonologists, hepatologists and, in particularly severe cases, transplant surgeons has been already proven successful.

Abstract
Interstitial lung disease (ILD) has been reported in patients with primary biliary cirrhosis (PBC); however, its frequency and pathogenesis are still poorly documented. Sjogren's syndrome (SS) is fairly common among patients with PBC, but the relationship between SS and PBC also remains controversial. To determine whether ILD and SS in PBC is a causal or casual association, whether SS accompanying PBC, could be considered secondary to or associated with PBC. One hundred and nine consecutive PBC cases were analyzed, and the differences of clinical features, histological stages, and serum autoantibodies between the PBC patients with and without SS were compared. There were 46 PBC patients with SS and 63 without SS, and 11 patients met the criteria of ILD. SS is associated with PBC in the form of secondary SS. The frequency of ILD in PBC patients with SS was 21.7% while only 1.6% in PBC patients without SS (P<0.0001). ILD in PBC was related to SS, with Spearman's rank coefficient of 0.330 (P=0.000). The association of SS with PBC, significantly higher in patients with than without ILD, which supports the hypothesis that ILD and SS in PBC, may be a causal, not casual, association.

Abstract
The collagen vascular diseases, also referred to as connective tissue diseases, are a diverse group of systemic inflammatory disorders thought to be immunologically mediated. The concept of collagen vascular disease began to take shape in the 1930s, when it was recognized that rheumatic fever and rheumatoid arthritis can affect connective tissues throughout the body.1,2 During the following decade, as conditions such as systemic lupus erythematosus (SLE) and scleroderma came to be viewed as systemic diseases of connective tissue, the terms diffuse connective disease and diffuse collagen disease were proposed.3,4 During the same period, the designation of diffuse vascular disease was proposed for diseases such as scleroderma, polymyositis, SLE, and polyarteritis nodosa, which featured widespread vascular involvement.5 With the realization that many of these entities can exhibit both systemic connective tissue manifestations and vascular abnormalities, the unifying designation of collagen vascular disease was introduced.6

Abstract
Primary biliary cirrhosis (PBC) is characterized by loss of tolerance against ubiquitously expressed mitochondrial autoantigens followed by biliary and salivary gland epithelial cell (BEC and SGEC) destruction by autoreactive T cells. It is unclear why BECs and SGECs are targeted. Previous work demonstrated that the reduced form of the major PBC autoantigen predominated in apoptotic BECs and SGECs as opposed to an oxidized form in other apoptotic cells. This led to the hypothesis that presentation of novel self-peptides from phagocytosed apoptotic BECs might contribute to BEC targeting by autoreactive T cells. The effect of autoantigen redox status on self-peptide formation was examined along with the phagocytic ability of BECs. Oxidation of PBC autoantigens first was shown to be due to protein S-glutathionylation of lipoyllysine residues. Absence of protein S-glutathionylation generated novel self-peptides and affected T cell recognition of a lipoyllysine containing peptide. Liver biopsy staining revealed BEC phagocytosis of apoptotic BECs (3.74+/-2.90% of BEC) was present in PBC (7 of 7 cases) but not in normal livers (0 of 3). BECs have the ability to present novel mitochondrial self-peptides derived from phagocytosed apoptotic BECs. Apoptotic cell phagocytosis by non-professional phagocytes may influence the tissue specificity of autoimmune diseases.

Abstract
A 55-year-old woman with a 6-year history of primary biliary cirrhosis presented with an acute onset of fever, dyspnoea, crackles over both lower lung fields, and diffuse interstitial and bibasilar patchy pulmonary opacities. After exclusion of an infectious aetiology, an open lung biopsy was performed which revealed two histopathological features: (1) bronchiolitis obliterans organising pneumonia and (2) lympho-histiocytic interstitial pneumonitis and destructive bronchiolitis. Treatment response to corticosteroids and azathioprine followed a bimodal pattern with immediate resolution of her initial presenting symptoms and late resolution of residual gas exchange defects.

Abstract
The association of primary biliary cirrhosis (PBC) and bronchial asthma was observed in three patients. All of these patients were female (53, 54, and 41 years old, respectively), and were positive for antimitochondrial antibodies. The patients fulfilled the diagnostic criteria of both PBC and bronchial asthma. Bronchial asthma preceded PBC in two patients, and the reverse order was seen in the other. Patient the clinical symptoms were mainly due to the bronchial asthma. Two patients had asymptomatic PBC and the third patient complained of pruritus. The liver histology showed mild to moderate eosinophilic infiltration in addition to the ductal and hepatic parenchymal changes characteristic of PBC. A survey of 266 cases of PBC referred to us disclosed that, in 6 of these, the PBC was associated with bronchial asthma, while no association with bronchial asthma was the material of found in 166 patients with viral hepatitis in our liver biopsy files. The 3 present cases we experienced suggest that bronchial asthma may be included in the list of extrahepatic diseases associated with PBC. The significance of this association is unclear and may merit further study. Steroid therapy, which is known to cause adverse effects in PBC, was employed for bronchial asthma in these 3 patients. Another therapeutic approach will have to be considered in patients with bronchial asthma associated with PBC.

Abstract
Sub-clinical lung impairment, mostly represented by a reduced diffusion of alveolar gases, is a recognised complication of advanced primary biliary cirrhosis. The aim of the study was to evaluate the prevalence and type of pulmonary involvement in primary biliary cirrhosis and the relationship between lung function abnormalities and selected epidemiological and clinical variables. Sixty-one patients with different stages of primary biliary cirrhosis consecutively seen in our outpatient clinic were evaluated. The advancement of primary biliary cirrhosis was characterised by the histological stage, the presence of signs of portal hypertension and the Mayo Risk Score: a Cox regression model using serum bilirubin and albumin levels, prothrombin time, age and degree of oedema as selected variables. We measured static and dynamic lung volumes, by means of a spirometer, and diffusing capacity for carbon monoxide. Rheumatological disorders were evaluated by an independent rheumatologist. No patient complained of respiratory symptoms. Airway obstruction was present in one patient. In 24 patients (39%) the alveolar diffusion capacity was reduced. We did not find any significant relationship between diffusing capacity and smoking habits, advancement of liver disease and concomitant Sjogren syndrome. Reduced diffusion capacity showed a significant correlation with the presence of complete or incomplete CREST syndrome (p < 0.01) and with the presence of circulating anti-centromere antibodies (p < 0.05). Alveolar diffusion capacity is frequently impaired in patients with primary biliary cirrhosis, usually in the absence of clinical manifestations. These alterations mostly affect patients with concomitant CREST syndrome.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Phagocytes, the first-line cells of the body's defence mechanisms against invading pathogens, kill microorganisms by means of lysosomal degradative enzymes and highly toxic reactive oxygen intermediates. The reactive oxygen compounds are produced, in a process called the 'respiratory burst', by the NADPH oxidase complex in plasma membranes, and by myeloperoxidase in phagolysosomes after degranulation. These processes generate electronically excited states which, on relaxation, emit photons, giving rise to phagocyte chemiluminescence (CL). This paper describes the conditions for the measurement of CL, and reviews the activity of phagocytes from individuals undergoing stress or disease. The capability of phagocytes to emit photons reflects remarkably well the pathophysiological state of the host. In many cases even the magnitude of the stress, the presence of a pathogen in the body, or the activity of the disease can be estimated. Physiological changes, e.g. in the reproductive cycle, can also be predicted.

Abstract
The purpose of this study was to determine the phenotype profiles of immune effector cells and the concentrations of immunoglobulins in the lower respiratory tract of non-smoking patients with alcoholic liver cirrhosis (ALC). Nine nonsmoking patients with liver biopsy-proved ALC (grade B or C cirrhosis in Child's classification), free of clinical pulmonary symptoms, and with normal chest roentgenogram were included in the study. The control group included 12 healthy nonsmokers. Each patient had fiberoptic bronchoscopy with bronchoalveolar lavage (BAL). The number of T cells and of lymphocyte subpopulations was determined by immunofluorescence studies using monoclonal antibodies that were specific for CD3, CD4, and CD8 markers. Patients with ALC exhibited a dramatically increased percentage of CD8+ cells in BAL that induced a low CD4/CD8 ratio (0.96 +/- 0.15 vs 1.8 +/- 0.12 in healthy controls). Further characterization of lymphocyte subsets' dual immunofluorescence analysis demonstrated that most of the CD8+ alveolar lymphocytes had a phenotype of cytotoxic cells (CD8+ CD11b-; 48 percent +/- 13 in ALC vs 10 percent +/- 5 in controls). ALC was associated with an appreciable alveolar-capillary "leak" as demonstrated by a significant increase in BAL fluid albumin. In addition, the concentrations of immunoglobulins in BAL fluid were significantly greater in ALC than in controls. However, the relative (to albumin) coefficient of excretion of IgG, A, and M in and alpha 2-macroglobulin BAL fluid was not significantly different between controls and ALC. Our results indicate that increased proportions of CB8+ and especially of CD8+ CD11b- cells are a common feature in the lower respiratory tract of nonsmoking patients with ALC. These changes may be of potential functional importance in the regulation of the local pulmonary immune response in ALC.

Abstract
Alcoholic individuals are predisposed to respiratory infections. However, mechanisms of perturbations leading to increased susceptibility to lung infections of individuals with alcoholic liver cirrhosis (ALC) are not fully understood. We studied the antibacterial activity and oxidant generation (before and after stimulation by phorbol myristate acetate or opsonized zymosan) of alveolar macrophages from 16 patients with ALC. Our results were compared with those obtained from 12 healthy control subjects, from 8 patients with primary biliary cirrhosis (PBC), and from 8 alcoholic individuals without cirrhosis. All were nonsmokers, had normal chest X-rays, and did not present evidence of lung infection 3 months before. The total number of cells recovered by bronchoalveolar lavage did not significantly differ between control subjects and patients. The cellular viability of alveolar macrophages (trypan blue exclusion) was greater than 90% in all cases. The antibacterial activity of alveolar macrophages versus Staphylococcus aureus was severely impaired in ALC (-21 +/- 8.2%) whereas it was normal in PBC (52 +/- 4.2%), in alcoholic subjects (44.6 +/- 5.4%), and in control subjects (60 +/- 5.5%). The same pattern of results was observed versus Escherichia coli (-47.7 +/- 10,28 +/- 8,28 +/- 12, and 29 +/- 8.5%, respectively). Previous incubation of normal alveolar macrophages with serum or BAL fluid from ALC patients or with normal serum or normal BAL fluid did not result in a significant decrease in antibacterial activity of normal alveolar macrophages. To distinguish ingested bacteria from adherent extracellular bacteria, cells that had been incubated with bacteria for 90 min were then incubated with lysostaphin (1 microgram/ml).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Subclinical alveolitis is a frequent finding in immunologic systemic disorders. However the significance of subclinical alveolar inflammation does not seem to be univocal and varies according to the disease. The fact that pulmonary involvement is rare during the course of extrathoracic granulomatosis like Crohn's disease or primary cirrhosis and that subclinical alveolitis is frequent suggests that alveolar inflammation may be the expression in the lung of a systemic immune disorder. In contrast subclinical alveolitis in collagen-vascular diseases, particularly progressive systemic sclerosis, is frequently associated with abnormalities of lung parenchyma as assessed by CT scan supporting the hypothesis that subclinical alveolitis is associated with development of ILD. Close follow-up of these patients is needed to better determine whether subclinical alveolitis precedes ILD and whether early detection of subclinical alveolitis in immunologic systemic disorders may identify those patients that are at risk for the development of ILD in the future.

Abstract
Follow-up of patients with subclinical inflammatory alveolitis associated with systemic diseases may represent the best opportunity to study the mechanisms responsible for the development of interstitial lung disease. We report a seven-year sequential pulmonary evaluation of one patient with clinically isolated gastric sarcoidosis, treated by gastrectomy, without evidence of clinical, radiologic or functional lung impairment and with chronic subclinical lymphocyte alveolitis. Five years later, she developed an overt interstitial lung disease characterized by fine crackles, diffuse parenchymal opacities and impaired diffusing capacity, preceded by an expansion of polymorphonuclear neutrophils in the lower respiratory tract, raising the hypothesis that these cells may be implicated in the pathogenesis of pulmonary derangement in sarcoidosis. This observation illustrates the importance of pulmonary follow-up of unaffected patients with systemic diseases and with subclinical inflammatory alveolitis, and the potential predictive value of neutrophil alveolitis in the pulmonary outcome of these patients.

Abstract
Chemiluminescence is a simple and reliable method of assessing phagocytic function. The bactericidal properties of phagocytes are dependent on the production of powerful oxidising species by the respiratory burst. These reactive oxygen radicals react with biological substrates to form excited compounds which then relax to their ground state by photon emission. This energy release is in the form of light which can be amplified by chemiluminescent probes and measured in a luminometer. Activation of cells is achieved using various agents that stimulate the respiratory burst. There is a close correlation between chemiluminescence and other methods of assessing phagocytic function, including bactericidal ability. The technique can be used to assess the function of polymorphonuclear leukocytes, monocytes, and tissue macrophages in response to disease, drugs, and toxins. This article describes the theory of cellular chemiluminescence, and the use of chemiluminescent probes and various cellular stimuli. Practical aspects of cell isolation and factors affecting chemiluminescence are considered. Finally, the clinical applications of chemiluminescence are discussed.

Abstract
Bronchoalveolar lavage was performed in eight patients with biopsy proved sarcoidosis and eight control subjects matched for age and smoking habit, three sequential 60 ml aliquots of sterile saline being used. Each aliquot was aspirated and analysed separately to determine total and differential cell counts. Cellular metabolic activity was stimulated with latex and measured by means of luminol enhanced chemiluminescence to assess neutrophil activity and lucigenin enhanced chemiluminescence to assess macrophage activity. In control subjects mean total cell counts were significantly greater in the second aspirate than in the first, but fell slightly in the third. Similarly, in the patients with sarcoidosis mean total cell counts increased from aspirate 1 to a maximum in aspirate 2, before falling again marginally in aspirate 3. The only significant difference in cell counts between patients with sarcoidosis and controls was an approximately threefold increase in total lymphocyte counts in the former in each of the three aspirates. Luminol chemiluminescence was similar in patients with sarcoidosis to that in controls in the first aspirate, but was significantly greater in the second and third aspirates. Lucigenin chemiluminescence was also significantly greater in the second and third aspirates only. Thus in patients with sarcoidosis lymphocyte numbers are increased in all three aspirates whereas cellular metabolic activity is increased to a greater extent in later aspirates, which may reflect events occurring in the periphery of the lung segment.

Abstract
Bronchial responsiveness to inhaled methacholine was measured four to six days before fibreoptic bronchoscopy in 22 asthmatic patients (10 smokers) and 20 control subjects (12 smokers). The asthmatic patients had a baseline FEV1 greater than 60% predicted and a PD20FEV1 (provocative dose of methacholine causing a 20% fall in FEV1) of 0.006-3.7 mg. The 20 control subjects had normal pulmonary function and a PD20FEV1 above the maximum cumulative dose of methacholine of 6.4 mg. Bronchoalveolar lavage of a middle lobe segment (lingula in four subjects) was performed with three sequential 60 ml aliquots of sterile saline. Cellular metabolic activity was stimulated with latex in aliquots of resuspended cells, and measured by means of luminol enhanced chemiluminescence to assess neutrophil activity and lucigenin enhanced chemiluminescence to assess macrophage activity. Mean absolute total cell counts were similar in the asthmatic and control groups but there were differences in differential cell counts, with a significant increase in eosinophil (p less than 0.05) and lymphocyte (p less than 0.005) counts in asthma. PD20FEV1 was negatively correlated with percentage neutrophil counts (p less than 0.005). Luminol enhanced chemiluminescence/1000 neutrophils was increased about twofold in asthmatic subjects (p less than 0.001), but was not correlated with PD20FEV1 Lucigenin enhanced chemiluminescence/1000 macrophages was increased nearly fourfold in asthmatic patients (p less than 0.001) and showed a negative correlation with PD20FEV1 (p less than 0.01). The macrophage count was increased twofold in current smokers in both groups, but other cell numbers were not altered significantly. Smoking did not affect cellular metabolic activity in either group. This study supports the idea that an inflammatory process is present in the airways of those with asthma, and suggests a relation between bronchial responsiveness and both neutrophil numbers and macrophage activity.

Abstract
A 65-year-old case diagnosed as primary biliary cirrhosis without definite signs of Sjögren's syndrome at age 62 developed interstitial lung disease, which was clinically, histologically, radiographically, and scintigraphically compatible with fibrosing alveolitis. Analysis of the cells in bronchoalveolar lavage fluid revealed, however, increased proportions of not only neutrophils but also lymphocytic cells, which were predominant. This case should focus attention on the association of primary biliary cirrhosis and fibrosing alveolitis.

Abstract
We initiated this study to determine the cellular composition and T-lymphocyte subpopulations of fluid from bronchoalveolar lavage from 15 patients with primary Sjögren's syndrome (1SS), six patients with secondary Sjögren's syndrome associated with primary biliary cirrhosis (2SS-PBC), eight patients with secondary Sjögren's syndrome associated with collagen-vascular diseases (2SS-CVD), and 12 normal subjects. All were nonsmokers who were free of clinical pulmonary symptoms and had normal findings on chest roentgenograms. Lymphocyte subsets were identified by mouse monoclonal antibodies that were specific for T-cells, helper/inducer, and suppressor/cytotoxic (namely, OKT3, OKT4, and OKT8). Patients with 1SS, patients with 2SS-PBC, and patients with 2SS-CVD had a significantly increased percentage of lymphocytes in fluid from bronchoalveolar lavage (respectively, 21.6 +/- 3.7 percent, 24.3 +/- 6.1 percent, and 25.6 +/- 3.9 percent) compared with the normal value of control subjects (9.9 +/- 1.5 percent). In addition, two of the 15 patients with 1SS and five of the eight patients with 2SS-CVD demonstrated an increased percentage of alveolar neutrophils. The predominant T-cell subset in patients with 1SS was T4+, and the mean T4:T8 ratio was normal. The percentage of T4+ cells was increased in patients with 2 SS-PBC, resulting in an increased T4:T8 ratio. In contrast, patients with 2 SS-CVD demonstrated a markedly increased percentage of T8+ cells, reflected by a shift in the T4:T8 ratio which was inverted. Patients with Sjögren's syndrome and with neutrophilia on bronchoalveolar lavage had a marked expansion of the T8+ lymphocyte subpopulation, where as patients with Sjögren's syndrome and with pure lymphocytosis on bronchoalveolar lavage showed predominantly T4+ cells. In addition, we found a strong positive correlation between the number of neutrophils and the number of T8+ cells in bronchoalveolar lavage from patients with Sjögren's syndrome (r = 0.74; p less than 0.05). Until the functional activities of OKT4+ and OKT8+ cells are better defined, the role that these cells play in the pathogenesis of pulmonary disease in Sjögren's syndrome remains unclear.
