1/86. Immunologically diagnosed malignancy in Sjogren's pseudolymphoma.Studies of lymphocyte markers in a patient with sjogren's syndrome who exhibited histologically benign lymphoproliferation in the lung revealed a malignant cell clone. T and B cells were quantitated according to their ability to form spontaneous rosettes with sheep erythrocytes and to fluoresce with fluorescein-conjugated antiserums, respectively. Circulating lymphocytes were 66 percent T cells (N = 58 /- 2 per cent) and 14 percent B cells (N = 22 /- 1 percent), the latter exhibiting normal polyclonal distribution of membrane immunoglobulins. However, lymphocyte suspensions obtained from fresh lymph node and from biopsy specimens from a lymphoid lung nodule revealed 95 percent and 88 percent B cells, with 1 percent and 2 percent T cells, respectively. Moreover, when cryostat-frozen sections from both tissues were reacted with each of the heavy and light chain-specific antiserums, most cells demonstrated the presence of intracytoplasmic mu kappa immunoglobulin exclusively. Twenty-two months later, a clinically and histologically classic lymphoma developed. Repeat marker studies performed on cells freshly isolated and on frozen sections from the histologically malignant lymph node revealed persistence of the monoclonal marker on most cells.- - - - - - - - - - ranking = 1keywords = cord (Clic here for more details about this article) |
2/86. Primary sjogren's syndrome in children and adolescents: proposal for diagnostic criteria.OBJECTIVE: Primary sjogren's syndrome (pSS) in childhood is a rare disease. Diagnostic criteria are available for adult patients only. In order to establish diagnostic criteria for juvenile pSS an analysis of 7 girls and one boy suffering from pSS with early onset is reported. Due to the rarity of the disease, data on patients with pSS reported in the literature are included in the proposal for modified diagnostic criteria. methods: The diagnosis of pSS was established according to the criteria for adulthood pSS, duly modified, which include clinical symptoms and laboratory immunological evaluation. RESULTS: The average age of our patients at clinical onset was 13.5 years (range: 10-17 yrs.). Clinical signs included systemic (fever, fatigue) as well as local (parotitis, vulvovaginitis, conjunctivitis) symptoms. paralysis due to hypokalemia linked to renal tubular acidosis and central nervous system (CNS) involvement was seen in one patient. Asymptomatic renal tubular acidosis was diagnosed in another 2 patients. Autoimmune hepatitis was present in 2 patients. All patients had laboratory abnormalities: hyperimmunoglobulinemia IgG, high titers of antinuclear antibodies (anti-SS-A and/or anti-SS-B) and elevated serum amylases. Sicca syndrome was never seen during childhood, although it developed later in 3 patients, after 7 to 10 years of follow-up. CONCLUSIONS: It has been stressed that the classical diagnostic criteria for adult sjogren's syndrome, especially sicca syndrome, are not applicable to a pediatric onset of the disease. On the other hand, the presence of typical laboratory abnormalities can allow the diagnosis of these patients in the early stages. Both laboratory and clinical symptoms typical for childhood are included in our proposal for diagnostic criteria applicable to juvenile pSS. life-threatening conditions such as hypokalemic paralysis, CNS involvement and hepatitis may also occur in children. Sicca syndrome tends to develop much later in pediatric patients.- - - - - - - - - - ranking = 1keywords = cord (Clic here for more details about this article) |
3/86. Primary sjogren's syndrome with severe central nervous system disease.OBJECTIVE: central nervous system (CNS) involvement in primary sjogren's syndrome (pSS) is controversial with regard to frequency, significance, and etiology. methods: We describe a young woman with pSS and severe CNS disease and review the literature on the pathophysiology, clinical significance, symptoms, diagnostic examinations, and treatment of CNS disease with concomitant pSS (CNS-SS). RESULTS: Our patient with pSS had a 5-month history of benign lymphadenopathy and myositis, after which she developed severe CNS disease, vasculitic lesions on her hands, and a neurogenic bladder attributable to spinal cord involvement. The diagnosis was based on the clinical picture and the results of a brain magnetic resonance imaging (MRI) scan, electroencephalography (EEG), and cerebrospinal fluid (CSF) analysis. The disease did not respond to corticosteroids, but the administration of cyclophosphamide resulted in recovery. In the literature, the incidence of CNS-SS varies widely, from rare to incidence rates of 20% to 25%. The clinical picture is diverse, ranging from mild cognitive symptoms to fatal cerebrovascular accidents. The pathophysiology of CNS-SS is unclear, specific diagnostic methods are not available, and diagnosis is based on the clinical picture and a combination of examinations. MRI is the most sensitive test and cerebral angiography the most specific. CSF reflects involvement of the leptomeninges, and EEG is nonspecific. There are no controlled studies of the treatment of CNS-SS. Regimens for vasculitis are commonly used. CONCLUSIONS: CNS-SS is uncommonly recognized and difficult to diagnose. Increasingly accurate and available diagnostic examinations will yield more information about the association of CNS disease with pSS.- - - - - - - - - - ranking = 18.037782246481keywords = spinal cord, spinal, cord (Clic here for more details about this article) |
4/86. Painful tonic/dystonic spasms in sjogren's syndrome.Three patients with sjogren's syndrome are presented in whom frequent tonic/dystonic spasms of the limbs developed during the course of the illness. These patients' clinical findings suggested spinal cord involvement, a localization that was confirmed by magnetic resonance imaging in two patients. In one patient the painful movements responded to treatment with phenytoin and in one other to baclofen. sjogren's syndrome should be considered in the differential diagnosis of conditions that produce tonic/dystonic limb spasms.- - - - - - - - - - ranking = 14.678742379265keywords = spinal cord, spinal, cord (Clic here for more details about this article) |
5/86. Acute self-limiting jejunitis as the first manifestation of microscopic polyangiitis associated with Sjogren's disease: report of one case and review of the literature.We report a case of acute self-limiting ulcerative jejunitis of unknown aetiology in a 72-year-old female patient in which a subsequent diagnosis of microscopic polyangiitis and sjogren's syndrome was made. All known causes of jejunal ulceration and inflammation were excluded. Previously reported cases of acute self-limiting jejunitis are reviewed and the possibility that acute jejunitis in this patient had been the first manifestation of systemic vasculitis is discussed.- - - - - - - - - - ranking = 10.232769638354keywords = inflammation (Clic here for more details about this article) |
6/86. Anti-adhesion molecule therapy as an interventional strategy for autoimmune inflammation.Functional inactivation of leukocyte adhesion molecules has been used to intervene in the development of tissue injury in experimental models of postperfusion infarction as well as autoimmune inflammation. We investigated the use of humanized monoclonal antibodies (mAb) against CD18 in the treatment of five patients with vasculitic tissue injury sufficient to threaten infarction or gangrene. The treatment was monitored in three ways: (i) whole-body gamma camera scintiscanning of autologous indium-labeled PMN, (ii) an index of the therapeutic inhibition of adhesion derived from comparison pre, during, and post mAb treatment of the ability of patients' PMN to be aggregated after activation by fMLP, and (iii) flow cytometric analysis of PMN CD18 expression. Four of five patients given anti-CD18 at 20 mg/day for up to 3 weeks showed prompt clinical improvement, with healing of the ulceration and restoration of limb function within 4 weeks, which was sustained. The fifth patient, who was not doing well clinically, decided to withdraw from all active treatment: at autopsy there was no evidence of the underlying vasculitis evident pretreatment. Our findings suggest that anti-adhesion molecule treatment might be an effective immediate treatment in severe vasculitis especially when tissue viability is threatened by progressive infarction and/or development of gangrene.- - - - - - - - - - ranking = 51.163848191771keywords = inflammation (Clic here for more details about this article) |
7/86. sjogren's syndrome with primary biliary cirrhosis, complicated by transverse myelitis and malignant lymphoma.A 53-year-old woman with sjogren's syndrome (SS) and primary biliary cirrhosis (PBC) complicated by transverse myelitis (TM) and malignant lymphoma (ML) is reported. TM has been described only in seven cases of primary SS, including three with PBC and four without PBC. The features of SS associated with PBC and complicated by TM were less typical compared with those seen in SS without PBC complicated by TM. This case is the first report of a case with SS, PBC, TM and ML. SS in association with PBC is, in general, overlooked, but such cases must be investigated with great caution for extraglandular complications.- - - - - - - - - - ranking = 1448.0750805963keywords = myelitis (Clic here for more details about this article) |

9/86. sjogren's syndrome with acute transverse myelopathy as the initial manifestation.This is the first report of a patient with acute transverse myelopathy as the initial manifestation of primary sjogren's syndrome (SS). The patient developed tetraparesis and sensory disturbance within 6 days of onset. Spinal MRI showed an extensive intraparenchymal lesion with high T2-weighted signal intensity, gadolinium enhancement, and cord swelling. Although the patient did not show clinical sicca symptoms, primary SS was diagnosed on the basis of clinical tests on lacrimal and salivary glands which showed high levels of autoantibodies. Treatment with prednisone improved motor and sensory symptoms and resulted in improvement of MRI findings. The present case suggests that acute transverse myelopathy can occur as an initial symptom of SS.- - - - - - - - - - ranking = 2026.376615915keywords = myelopathy, cord (Clic here for more details about this article) |
10/86. Treatment of myelopathy in Sjogren syndrome with a combination of prednisone and cyclophosphamide.BACKGROUND: Peripheral neuropathy is a common complication of primary Sjogren syndrome, but central nervous system involvement also occurs and may be the only extraglandular manifestation. Sicca symptoms may also be minimal. Combinations of lesions along with relapses and remissions can suggest multiple sclerosis in the proper clinical setting, making the correct diagnosis elusive. OBJECTIVES: To report a case of progressive transverse myelopathy with previous optic neuropathy in primary central nervous system Sjogren syndrome (CNS-SS), and to review 17 previously reported cases and the patient's responses to various therapies. DESIGN: Case report and literature review. SETTING: University hospital. PATIENT: A 63-year-old Hispanic woman with a 10-month history of progressive spastic paraparesis associated with optic neuropathy and a T10 sensory level. magnetic resonance imaging demonstrated multifocal, contrast-enhancing lesions in the spinal cord. The patient was diagnosed as having CNS-SS because of the presence of sicca symptoms, abnormal serological test results, and salivary gland biopsy results, which fulfilled San Diego criteria for "definite" Sjogren syndrome. She responded to treatment with a combination of prednisone and cyclophosphamide. CONCLUSIONS: diagnosis of primary CNS-SS requires a high index of suspicion and specialized clinical testing. Treatment with pulse doses of corticosteroids alone may be suboptimal, but results of treatment with a combination of corticosteroids and either cyclophosphamide or chlorambucil have been encouraging.- - - - - - - - - - ranking = 1702.4925889751keywords = myelopathy, spinal cord, spinal, cord (Clic here for more details about this article) |
