1/5. Clinical and laboratory findings in immunocompetent patients with persistent parvovirus B19 dna in bone marrow.The clinical relevance of parvovirus B19 dna persistence in bone marrow was examined in 10 immunocompetent individuals undergoing examinations for unexplained fever, arthralgia or chronic leukopenia. Common causes of these symptoms had been ruled out and bone marrow aspiration was indicated at this stage of investigation. In addition to morphological analysis of the bone marrow, a test for B19 dna was performed with 2 nested PCRs. Five of these 10 selected patients had detectable B19 dna in their bone marrow, whereas no viraemia was observed. Additional bone marrow samples were collected at least 6 months after the first sample from the B19 dna-positive patients, of whom 3 were found to be still positive. Indeed, 2 of the patients have been positive for more than 5 y of follow-up. Sera from all patients with persistent B19 dna in bone marrow could neutralize the virus. One patient responded to treatment with immunoglobulin but later relapsed. No other cause of the symptoms was found, despite extensive investigations, and at least some of the prolonged disease manifestations may be due to parvovirus B19.- - - - - - - - - - ranking = 1keywords = still (Clic here for more details about this article) |
2/5. hepatitis b-assocciated adult-onset Still's disease presenting with neutrophilic urticaria.adult-onset Still's disease (AOSD) is an uncommon systemic inflammatory disorder that is characterized by quotidian fever, articular manifestations, neutrophilic leukocytosis, and maculopapular rash. The aetiology of the disease is unknown, however, an infectious cause has been suggested. Here we describe a patient in whom neutrophilic urticaria was the cutaneous manifestation of AOSD. In addition, the patient suffered from chronic hepatitis b infection that may be a potential trigger factor of AOSD. In patients with AOSD, serological investigations for detection of infection should include hepatitis serology. Further, we suggest that urticarial lesions may be a more common cutaneous manifestation of AOSD than has been recognized previously. Thus it is important to include AOSD in the differential diagnosis of urticaria.- - - - - - - - - - ranking = 0.34386569276032keywords = adult-onset (Clic here for more details about this article) |
3/5. vasculitis of the aortic arch and cardiac valves as the cause of relapsing fever of unknown origin in an elderly, white man.Here, we report the case of fever of unknown origin (FUO) in a 77-year-old white man. The patient presented with a 3-week history of fever (between 38.5 and 39 degrees C) and general malaise. These symptoms had occurred about five to seven times during the past 30 years, and despite repeated hospitalizations, no diagnosis was made. physical examination did not reveal any specific signs of infection nor did the patient fulfill the criteria for any rheumatic disease including vasculitides. blood chemistry showed a greatly elevated c-reactive protein (CRP; 158.2 mg/l) and an erythrocyte sedimentation rate >100 mm, indicating an active inflammatory process, and leukocytes were significantly elevated (20,000/mul). Rheumatological parameters showed only nonspecific changes. Finally, a 2-[(18)F]-fluoro-2-deoxy-D: -glucose-positron emission tomography was performed, revealing a markedly enhanced glucose uptake in the ascending aorta and the cardiac valves, indicating vasculitis as the cause of FUO in this patient. Based on this finding, treatment was started with corticosteroids, and 2 days after the initiation of treatment, the patient had normal body temperature, and after 5 days, CRP values had returned to normal. After tapering and final complete removal of steroid treatment, the patient was still free of symptoms, hence no disease-modifying antirheumatic drug therapy was necessary.- - - - - - - - - - ranking = 1keywords = still (Clic here for more details about this article) |
4/5. adult-onset Still's disease revealed by a pleuropericarditis.We report a case of adult-onset Still's disease (AOSD) revealed by pleuropericardial manifestations. A 40 yr old black woman was admitted for flu-like syndrome with pharyngitis, hectic fever, polymorphonuclear hyperleucocytosis and pleuropericarditis. The diagnosis of AOSD was supported by 3 major and 3 minor criteria after exclusion of infectious, haematological and connective tissue diseases. Pulmonary involvement is infrequent in AOSD, and consists of transient pulmonary infiltrates and chronic restrictive pattern. However, pleuritis, like pericarditis, is present in 25% of cases. Initial onset of pleuritis, associated with fever and hyperleucocytosis preceding articular manifestations could be responsible for a delay in diagnosis and a subsequent worsening in the prognosis of the disease. A rapid improvement is usually observed under nonsteroidal anti-inflammatory drug or corticosteroid treatment.- - - - - - - - - - ranking = 0.085966423190081keywords = adult-onset (Clic here for more details about this article) |
5/5. fever of unknown origin responding to steroid therapy.It is not uncommon to find cases of fever of unknown origin (FUO) in which no final diagnosis is made ever after various examinations. We investigated such cases of undiagnosed FUO, with fever persisting for a long periods and responding to steroid therapy. Among 4,596 patients who were hospitalized over 3-year period from September 1991, 25 met Petersdorf's definition of FUO. Among these 25 patient, six cases were steroid-responsive undiagnosed FUO (SR-FUO). patients with SR-FUO had the following characteristics: marked inflammatory findings and severe illness; without a definite underlying disease being found despite various examinations; no findings which indicated any known diseases such as adult-onset Still's disease, polymyalgia rheumatica, or other collagen diseases; elderly onset, at 58 to 77 years of age (mean age: 67 years); no improvement with antibiotics, antituberculous agents, or antimycotic drugs; significant improvement of symptoms and signs with steroid therapy; and a relatively good prognosis. SR-FUO, which is not caused by any known disease and is highly responsive to steroids, is included among the FUO cases which we have difficulty in diagnosing and treating.- - - - - - - - - - ranking = 0.085966423190081keywords = adult-onset (Clic here for more details about this article) |
