Joint involvement consists of swelling or tenderness upon examination. The presence of synovitis may be confirmed on imaging studies. Points are allocated as follows: 1 large joint (ie, shoulders, elbows, hips, knees, ankles) = 0 points 2-10 large joints = 1 point 1-3 small joints (with or without involvement of large joints) (ie, MCP, PIP, second-fifth MTP, thumb IP, and wrist joints ) = 2 points 4-10 small joints (with or without involvement of large joints) = 3 points More than 10 joints (at least 1 small joint, plus any combination of large and additional small joints or joints such as temporomandibular, acromioclavicular, sternoclavicular, etc) = 5 points At least 1 serology test result is needed for classification. Points are allocated as follows: Negative RF and negative ACPA = 0 points Low-positive RF or low-positive ACPA = 2 points High-positive RF or high-positive ACPA = 3 points

It is a systemic autoimmune disease in which immune cells attack and destroy the exocrine glands that produce tears and saliva Sjögren's syndrome can exist as a disorder in its own right (Primary Sjögren's syndrome) or it may develop years after the onset of an associated rheumatic disorder such as rheumatoid arthritis, systemic lupus erythematosus, scleroderma, primary biliary cirrhosis etc. (Secondary Sjögren's syndrome). Sicca symptoms (dry eyes and dry mouth) Parotitis Patients with Sjögren syndrome may have a history of recurrent parotitis, often bilateral. Although in some patients the parotid glands become so large that the patients report this as a problem, more often the examining physician discovers them. Cutaneous symptoms Nonvasculitic cutaneous manifestations in Sjögren syndrome include dryness, eyelid dermatitis, pruritus, and erythema annulare. Cutaneous vasculitis, such as palpable purpura, develops in some patients with Sjögren syndrome, especially those with hypergammaglobulinemia or cryoglobulinemia.[31, 32] Raynaud phenomenon is observed in approximately 20% of patients. Pulmonary symptoms Patients with Sjögren syndrome can develop dryness of the tracheobronchial mucosa (xerotrachea), which can manifest as a dry cough. Less often, patients develop dyspnea from an interstitial lung disease that is typically mild.[33, 34]Patients may develop recurrent bronchitis or even pneumonitis (infectious or noninfectious). Gastrointestinal symptoms Dryness of the pharynx and esophagus frequently leads to difficulty with swallowing (deglutition), in which case patients usually describe food becoming stuck in the upper throat. Lack of saliva may lead to impaired clearance of acid and may result in gastroesophageal reflux and esophagitis. Abdominal pain and diarrhea can occur. Rarely, patients develop acute or chronic pancreatitis, as well as malabsorption due to pancreatic insufficiency. However, caution is advised when interpreting laboratory results because an elevated amylase level may arise from the parotid gland. In patients with gastritis, Helicobacter pylori infection should be sought because of its association with gastric mucosa-associated lymphoid tissue lymphomas. Patients with Sjögren syndrome are at increased risk for delayed gastric emptying, which can cause early satiety, upper abdominal discomfort, nausea, and vomiting. Cardiac symptoms Pericarditis and pulmonary hypertension, with their attendant symptomatology, can occur in Sjögren syndrome. Orthostatic symptoms related to dysfunction of autonomic control of blood pressure and heart rate is associated with increased severity of Sjögren syndrome. Neurologic symptoms The occurrence of central nervous system (CNS) and spinal cord involvement in Sjögren syndrome is estimated by various studies to be 8-40%, with manifestations including myelopathy, optic neuropathy, seizures, cognitive dysfunction, and encephalopathy.[24, 39, 40] Attempts must be made to distinguish other causes of these symptoms, including concomitant SLE, multiple sclerosis, cerebrovascular disease, and Alzheimer disease. Sensory, motor, or sensorimotor peripheral neuropathy, often subclinical, can be detected in up to 55% of unselected patients with Sjögren syndrome.Symptoms of distal paresthesias may be present. Cranial neuropathies can develop, particularly trigeminal neuropathy or facial nerve palsy. Mononeuritis multiplex should prompt a search for a vasculitis. Progressive weakness and paralysis secondary to hypokalemia due to underlying renal tubular acidosis can occur and is potentially treatable. Renal symptoms Renal calculi, renal tubular acidosis, and osteomalacia, nephogenic diabetes insipidus, and hypokalemia can occur secondary to tubular damage caused by interstitial nephritis, the most common form of renal involvement in Sjögren syndrome. Interstitial cystitis, with symptoms of dysuria, frequency, urgency, and nocturia, is strongly associated with Sjögren syndrome.[43, 44] Glomerulonephritis can be caused by Sjögren syndrome but is uncommon and is usually attributable to another disorder, such as SLE or mixed cryoglobulinemia.

Infectious agents: Chlamydiae, Salmonella, Shigella, Yersinia, Campylobacter yellowish serous papules at soles and palms even nails, scrotum, scalp and trunk.
Diagnostic tests: Angiotensin converting enzyme (ACE) Hypercalcemia Panda and lambda pattern gammagraphy Bronchoalveolar lavage (BAL)- Transbronchial lung biopsy (TBLB): The earliest pathologic finding in patients with sarcoidosis is a mononuclear alveolitis composed of increased CD4+lymphocytes (with an increased CD4/CD8ratio), monocyte-macrophages, and rare B lymphocytes.
Possible physical findings on slit lamp examination include blepharitis, atopic keratoconjunctivitis (AKC) scarring of the palpebral conjunctiva, papillary conjunctival reaction, Trantas dots (limbal deposits of eosinophils), atopic cataracts, and keratoconus. Unlike vernal conjunctivitis, the lower tarsus is involved more frequently. Hyperemia, chemosis, and discharge are more common than papillary or cobblestone reaction. Atopic cataracts develop in patients with long-standing atopic disease (10 or more years).These patients usually are older children or young adults. The incidence of atopic cataracts is estimated to be 10%, and they are most frequently bilateral. These cataracts tend to evolve rapidly and may opacify within 6 months. The cataracts often begin as a posterior subcapsular opacity and develop into an anterior cortex opacity that frequently resembles the shape of a shield or a bearskin rug.
