Objective.The risk of clinically manifested major cardiovascular (CV) events in primary Sjögren syndrome (pSS) remains unclear. This study aimed to assess myocardial fibrosis in pSS and investigate the associated disease characteristics by cardiac magnetic resonance imaging (cMRI).Methods.We performed a cross-sectional study of patients with pSS without cardiac symptoms. Labial gland biopsy was documented in 44 patients (85%). Patients without CV risk factors underwent contrast-enhanced cMRI. Late gadolinium enhancement (LGE) was used to assess myocardial fibrosis. Myocardial edema was assessed using T2-weighted imaging (T2WI). We compared the left ventricular (LV) geometry and function between the groups with and without LGE. Further, we explored the associations of cMRI abnormalities with pSS characteristics.Results.Fifty-two women with pSS (median age 55, IQR 47.0–65.7 yrs) were enrolled in the study. LGE was observed in 10 patients (19%), two of whom showed high intensity on T2WI. High intensity on T2WI was observed in 3 patients (5.8%). LV mass index and LV mass/end-diastolic volume tended to be higher in the LGE-positive group than in the LGE-negative group (P = 0.078 and 0.093, respectively). Salivary gland focus score (FS) ≥ 3 was independently associated with LGE-positive in the multivariable analysis (OR 11.21, 95% CI 1.18–106.80).Conclusion.Subclinical myocardial fibrosis, as detected by cMRI, was frequent in patients with pSS without cardiac symptoms. Abnormal cMRI findings were associated with salivary gland FS ≥ 3.

We report a 68-years-old woman with systemic sclerosis and interstitial pneumonia (IP). She had developed subacute progressively encephalopathy and dementia while treated with oral cyclophosphamide and prednisolone. She admitted to our hospital because of syncope. Laboratory tests indicated slight elevated cerebrospinal fluid protein, and levels of serum C-reactive protein (CRP), levels of soluble IL-2 receptor was normal. But, magnetic resonance imaging (MRI) of the brain showed multiple infarct-like lesions mainly in the white matter, which mimics progressive multiple leukoencephalopathy (PML). Twenty days after admission, the retested MRI of the brain disclosed initial lesions progressively enlarged and numbers of the lesions were increased. The polymerase chain reaction (PCR) for JC virus of cerebrospinal fluid was negative. To make diagnosis, brain biopsy was performed. Microscopic examination revealed that small vessels were filled with lymphoma cells (CD20+, CD79+, CD3-), and intravascular lymphoma (IVL) was diagnosed. She treated with regimens of R-CHOP. After chemotherapy her consciousness and dementia were gradually improved. IVL of central nerve system (CNS) is a rare disease, and its common symptoms are ischemia, infarction and dementia. Diagnosis of IVL of CNS is difficult when the lesion mimics PML, and patient with similar laboratory examinations and radiographic findings of PML should undergo brain biopsy detected malignant cell in small vessels, which is a value of diagnosis.

Background: Elderly acute myeloid leukemia (AML) patients and patients with higher-risk myelodysplastic syndromes (MDS) have a much poorer prognosis than younger patients despite intensive chemotherapy. Methods: Ten patients with higher-risk MDS and 12 patients with AML over 65 years of age were enrolled into this study and received oral induction therapy with cytarabine ocfosfate and etoposide. Results: The therapy response rates were 60% in the MDS group and 41.7% in the AML group. The difference in overall survival among MDS and AML patients was not statistically significant. The difference in the median survival times of the responsive and nonresponsive groups, which included MDS and AML patients, was statistically significant (790 and 174 days, respectively). Conclusions: Based on a comparison of the data of this therapy in elderly higher-risk MDS patients versus elderly AML patients, we conclude that this therapy is well tolerated and can be cost-effective and useful for higher-risk MDS in elderly patients.

Objectives Minodronic acid hydrate, an oral bisphosphonate, has a greater inhibitory effect on bone resorption than do other approved drugs; however, this has been studied only in patients with primary osteoporosis. Here, we administered minodronic acid hydrate to patients with steroid-induced osteoporosis who have been treated with steroids for rheumatoid arthritis or other collagen diseases, and the efficacy and safety of minodronic acid hydrate were prospectively investigated. Methods Twenty-five patients treated in our rheumatology clinic received minodronic acid hydrate 1 mg/day. The changes in bone mineral density (BMD) and bone turnover markers were investigated at 3 and 6 months, and adverse events, including the presence or absence of an incident osteoporotic fracture, were examined over a period of 6 months. Results Percent changes in BMD of the lumbar spine and femur significantly increased. The values of bone turnover markers significantly decreased. There were no patients with a radiographically apparent incident fracture. Adverse events included toothache for which the patient discontinued the treatment and three cases of gastrointestinal disorder that did not lead to discontinuation, and thus minodronic acid hydrate was well tolerated. Conclusions Here, we show that minodronic acid hydrate is effectively and safely used for treatment of steroid-induced osteoporosis.

Although the effects of angiotensin II receptor blockers (ARBs) on non-diabetic glomerulonephritis have been reported, studies of their effects on collagenvascular diseases, particularly lupus nephritis, are limited. In this retrospective, observational study, systemic lupus erythematosus (SLE) patients ( n = 7) with lupus nephritis and uncontrolled proteinuria were treated with an angiotensin-converting enzyme inhibitor followed by the ARB losartan (25–50 mg/day). Urinary protein excretion and renal function were evaluated. After 12 months of losartan, mean urinary protein excretion decreased significantly by 84.8%. Mean systolic and diastolic blood pressures also decreased significantly during the 12 months of losartan treatment, although not in normotensive patients. Complement 4, total complement activity and anti-dsDNA antibody levels, which are indices of SLE activity, and serum creatinine levels, which is an index of renal function, showed no change in response to losartan treatment. A more extensive evaluation of the effects of ARBs in patients with lupus nephritis and poorly controlled proteinuria is required.

To evaluate the vulnerability of the central nervous system (CNS) in patients with systemic lupus erythematosus (SLE).Forty-eight patients with SLE, 58 with schizophrenia in remission and 39 healthy controls were enrolled in the study. Patients vocally generated 100 numbers in a random fashion, using numbers 0 to 9, and were evaluated with seriality scores. Patients with SLE were subgrouped according to differences in the presence of Raynaud's phenomenon, anti-phospholipid antibody, lupus activity, and a history of neuropsychiatric (NP) lupus, and these patients were also evaluated by comparison with their counterparts.In general, patients with SLE showed lower seriality scores than patients with schizophrenia, and higher seriality scores than normal controls. The scores of the patients with a history of NP lupus matched those with schizophrenia, and the scores of never having NP lupus matched those of the healthy controls.CNS vulnerability may be prolonged in patients who have a history of NP lupus even when they appear to be in normal NP status. The damage in random number generation (RNG) observed in patients with a history of NP lupus seemed equal to that found in those with schizophrenia, whereas those patients never having NP lupus appeared to be equal to the controls. The current study suggests a heterogeneous nature of SLE and prolonged damage, especially in CNS vulnerability, when evaluating with RNG.

We report a rare case of systemic lupus erythematosus (SLE) complicated by alveolar hemorrhage and cytomegalovirus (CMV) colitis. Despite the successful treatment of lupus nephritis by steroid pulse therapy, the patient developed an acute alveolar hemorrhage 2 months later. Cyclophosphamide pulse therapy ameliorated the hemorrhage. One month later, she suddenly developed melena secondary to CMV colitis. Antiviral therapy was successful. We emphasize the importance of timely and precise differential diagnosis for successful management of complicated SLE.

Objective To examine whether Coxiella burnetii (C. burnetii) is involved in chronic fatigue syndrome (CFS), we administered tetracycline antibiotics to subjects with CFS, and followed changes in clinical symptoms, PCR findings, and C. burnetii antibody titers.Patients and Methods The subjects were 8 patients with CFS and 213 with nonspecific complaints such as chronic fatigue and low-grade fever for several months or longer but not meeting the diagnostic criteria for CFS. All were examined for C. burnetii infection by nested PCR and the indirect immunofluorescence test (IF).Results Four CFS patients (the CFS group) and 54 controls [the post-Q fever fatigue syndrome (QFS) group] positive for C. burnetii were treated mainly with minocycline or doxycycline (100 mg/day) for 3 months. After treatment, all 58 patients tested negative for C. burnetii infection. In the CFS group, no significant difference was noted between the mean pre- and post-treatment temperatures or headache scores. Similarly, there was no significant improvement in performance status (PS) scores. In the QFS group, however, mean temperatures and headache scores were significantly decreased after treatment (p

A 65-year-old Japanese woman was diagnosed in 1996 with a pathological fracture of the left femur caused by immunoglobulin D-type myeloma (IgD myeloma). She responded well to combination chemotherapy followed by irradiation. The patient experienced renal failure and became dependent on haemodialysis. In 1999, large plasmacytomas developed in the abdomen and left humerus. The abdominal tumour appeared to induce gastroduodenal ulcers and jejunal obstruction. We initiated irradiation therapy without chemotherapy to prevent further growth of the plasmacytoma, although treatment-resistant gastroduodenal ulcers developed. Continued blood loss from the gastroduodenal ulcers resulted in a deterioration in the patient's health, which prevented successful haemodialysis. An autopsy showed that the plasmacytoma had undergone coagulation necrosis. We conclude that the use of combination chemotherapy with topical irradiation was an acceptable treatment measure against IgD plasmacytoma; irradiation without chemotherapy was the most likely cause of the coagulation necrosis seen in the plasmacytoma at autopsy.

Objectives - To estimate the effect of brain function due to IFN-alpha in chronic hepatitis C patients by the quantitative EEG. Methods - 56 chronic hepatitis C patients were administered IFN-alpha intramuscularly at 9×10 6 IU daily for the first 4 weeks and then 3 times/week for the next 20 weeks. Serial EEGs were obtained in each subject before, at 2 and 4 weeks, and after completing the treatment. Resting EEG without artifacts was selected for quantitative EEG analysis, which was performed blindly. The frequency range was divided into delta to beta. The absolute and relative powers of each frequency band in each subject were calculated and the differences of these powers at different stages were analyzed statistically. Results - The absolute powers of slow waves (delta, theta 1, and theta 2) increased while alpha 2 and fast wave (beta) decreased significantly at all locations during IFN-alpha administration. The total power and alpha 1 values revealed no significant alterations. The relative power revealed the same alteration during treatment. These changes disappeared following the treatment. Such diffuse slowing in the EEG was revealed by the total change in the whole subjects. Conclusions - Diffuse slowing in the EEG was induced by IFN-alpha, was reversible, and was evident as the total change in the subjects. These findings suggested mild IFN-alpha-induced encephalopathy.

We have encountered five hemodialysis patients who had received enteral nutrition and recovered from erythropoietin-resistant anemia with neutropenia after the correction of copper deficiency. We reduced the required doses of recombinant human erythropoietin (rHuEPO) to maintain the target hematocrit levels and three patients were finally weaned from the rHuEPO therapy. Thus, copper deficiency is involved in erythropoietin-resistant anemia in hemodialysis patients.

Beyond the obvious step of limiting use of non-steroidal anti-inflammatory drugs (NSAIDs), the treatment of ulcers induced by NSAIDs remains controversial. We evaluated the efficacy of the proton-pump inhibitor lansoprazole on NSAID-induced ulcers. Ulcers were endoscopically diagnosed in 47 NSAID users. These patients received 30 mg/day lansoprazole, orally, for 6 or 8 weeks (6 weeks for duodenal ulcers and 8 weeks for other ulcers). Ulcer healing was assessed using an established classification system. The presence of immunoglobulin G antibody against Helicobacter pylori was also evaluated. The antibody was present in the sera of 51% of patients (24/47). Most of the ulcers reached scarring stages S1 (healing) or S2 (good healing), and the S2 healing rate was 35%. Two H. pylori seropositive patients did not reach these stages; their ulcers were improved by H. pylori eradication therapy, followed, in one case, by medication with misoprostol. Lansoprazole seemed to be useful for most patients with NSAID-induced ulcers, but a few needed additional treatments.

A 59-year-old patient with schizophrenia developed Sjögren's syndrome. She also presented with the lupus anticoagulant attributed to long-term medication with chlorpromazine. Serial plasmapheresis treatments were performed to decrease the anti-coagulant activity. As a result, the activated partial thromboplastin time was temporarily improved, but the lupus anti-coagulant activity did not change. Because of her unstable emotional state, she continued to require chlorpromazine, but took a low dose of aspirin (87 mg/day) and never manifested any signs of thrombotic events. In view of the potential anti-thrombotic effects of chlorpromazine, it may not be necessary to use plasmapheresis in an attempt to reduce anti-coagulant activity among patients with chlorpromazine-induced lupus anti-coagulant.

To investigate the clinical characteristics and risk factors of Pneumocystis jirovecii pneumonia (PCP) in rheumatoid arthritis (RA) patients treated with adalimumab.We conducted a multicenter, retrospective, case-control study to compare RA patients treated with adalimumab with and without PCP. Data from 17 RA patients who were diagnosed with PCP and from 89 RA patients who did not develop PCP during adalimumab treatment were collected.For the PCP patients, the median age was 68 years old, with a median RA disease duration of eight years. The median length of time from the first adalimumab injection to the development of PCP was 12 weeks. At the onset of PCP, the median dosages of prednisolone and methotrexate were 5.0 mg/day and 8.0 mg/week, respectively. The patients with PCP were significantly older (p0.05) and had more structural changes (p0.05) than the patients without PCP. Computed tomography of the chest revealed ground-glass opacity without interlobular septal boundaries in the majority of the patients with PCP. Three PCP patients died.PCP may occur early in the course of adalimumab therapy in patients with RA. Careful monitoring, early diagnosis, and proper management are mandatory to secure a good prognosis for these patients.

Despite many suicidal cases in patients with systemic lupus erythematosus (SLE), literature on this subject is lacking. To elucidate and prevent this phenomenon, we re-evaluated the clinical records of seven suicidal patients with SLE. Six patients had photosensitivity and insomnia. At the time of the suicide attempt, hypocomplementemia was observed in five of six patients. Diffuse slowing on electroencephalograms were observed in four of five patients. One patient successfully committed suicide while on no therapy while five patients made their attempts under the tapering courses of steroids. Five patients manifested psychoses whereas two patients displayed no psychotic findings. All patients attempted suicide shortly after admission (mean time 20 days). The subsequent courses of the survivors who received more medication were favorable. Therefore, it appears that disease activity was not fully controlled in these patients. Furthermore, signs of an imminent suicide attempt were missed in some cases. Psychosis, insomnia, history of photosensitivity, an incompletely controlled disease state, receiving tapering steroid dose, diffuse slowings on electroencephalograms and the presence of hypocomplementemia appeared to be risks for attempting suicide in SLE. We would recommend that such patients be under psychiatric care for at least 2 months to prevent suicide. When the patient is still psychotic or unstable, further medical care will be required.

Two women with rheumatoid arthritis who had experienced miscarriages became pregnant while they were under etanercept treatment. One stopped etanercept after 3 weeks with increased doses of prednisolone, and the other restarted etanercept at a half doses 3 months later. They delivered a healthy baby at full term, and no problems in both expecting mothers and babies were observed. The use of etanercept in patients with rheumatoid arthritis seemed safe for pregnant mothers and their fetuses.

To evaluate the influence of Helicobacter pylori and sex difference on peripheral platelet counts, dyspeptic patients without immunohaematologic disorders were evaluated. H. pylori infection was verified with the rapid urease test and serum anti-H. pylori IgG antibody. Platelet counts were analysed with a reference to H. pylori infection and sex difference. Among H. pylori-eradicated patients, changes in platelet counts were separately evaluated. Totally, 655 patients were enrolled: 340 patients were infected with H. pylori and 178 patients received eradication therapy, with a success rate of 88.2% (157/178). Females with H. pylori infection definitely manifested elevated platelet counts (infected vs. uninfected 244 ± 57 vs. 219 ± 54 × 10(9)/l; p0.0001). H. pylori eradication reduced peripheral platelets by 8 weeks, 5-6 months, 1, 2 and ≥3 years after eradication in females from 248 ± 54 to 237 ± 49, 237 ± 54, 229 ± 48, 238 ± 61 and 232 ± 50 × 10(9)/l (p = 0.0003, 0.0182, 0.0041, 0.0398 and 0.0289), respectively. In males, the reduction was verified by 8 weeks, 1 year and ≥3 years from 226 ± 52 to 217 ± 47, 214 ± 44 and 200 ± 49 × 10(9)/l (p = 0.0464, 0.0164 and 0.0016), respectively. In conclusion, H. pylori infection upregulates platelet counts mainly in females, and eradication reduced peripheral platelets in both sexes. Females appeared more susceptible to H. pylori infection than males with regard to upregulation of platelet counts.

The incidence of systemic fungal infections has risen, as shown by increases in the numbers of immunosuppressed or immunocompromised patients. The consequences of these fungal infections are occasionally serious. However, the efficacy of antifungal prophylaxis in patients receiving corticosteroid treatment has not been well investigated, even though they are susceptible to severe fungal infections. Therefore, we retrospectively evaluated the prophylactic efficacy of an antifungal agent—oral itraconazole solution (ITCZ-OS)—for immunosuppressed patients receiving corticosteroids in a single institution. Of 39 patients, 18 received prophylaxis with ITCZ-OS at a dose of 200 mg/day, and 21 did not. As a result, no fungal infections developed in the prophylactic group, but 7 of the 21 patients (33%) in the non-prophylactic group suffered from fungal infections consisting of 3 non-invasive candidiases, 2 invasive candidiases, and 2 invasive pulmonary aspergilloses. Among the non-prophylactic group, aging and hypoalbuminemia were statistically significantly associated with incidence of invasive fungal infections. Of the four patients with invasive fungal infections, three had concomitant chronic illness such as diabetes. Toxicity among the prophylactic group was not statistically significantly different from that of the non-prophylactic group. In addition, none needed discontinuation of the drug. These results indicate the potential antifungal prophylactic effect of ITCZ-OS for a subset of patients treated with moderate or high doses of corticosteroids.

Helicobacter pylori eradication is becoming a first-line therapy against idiopathic thrombocytopenic purpura (ITP) and its long term efficacy has already been reported. In contrast, eradication therapy reduced peripheral platelets in non-ITP patients 8 weeks later. To confirm the long term efficacy of Helicobacter eradication on platelet counts in non-ITP patients, we evaluated changes in peripheral platelet counts in endoscopically diagnosed patients with Helicobacter infection. Endoscopically diagnosed patients with Helicobacter infection received eradication therapy using amoxicillin (1500 mg/day), clarithromycin (400 mg/day) and lansoprazole (60 mg/day). The changes in platelet counts after Helicobacter eradication were serially evaluated for as long as 3 years or more. In total, 294 patients were enrolled: 243 patients successfully received eradication therapy and 51 were unsuccessfully treated. As a whole, peripheral platelet counts significantly decreased after Helicobacter eradication, being reduced by more than 1.0 × 10⁹/l by 5-6 months, 1 year, 2 years and 3 years or more (from 24.2+/-5.6 to 23.1+/-5.0, 23.0+/-5.0, 22.1+/-4.5, 22.4+/-5.6, and 21.6+/-5.3 × 10⁹/l: p =0.0001,0.0001, 0.0001, 0.0052, and0.0001, respectively). Helicobacter pylori eradication finally reduced peripheral platelet counts around 2.0 × 10⁹/l in non-ITP patients. There was a definite difference in platelet regulation by Helicobacter pylori between ITP and non-ITP patients. These bivalent effects, upregulation and downregulation, on the peripheral platelet induced by Helicibacter pylori infection appeared to originate from quite different mechanisms.

Precise mechanism of developing neuropathic arthropathy known as Charcot's joint is not fully understood.A 55-year-old Japanese woman with neurofibromatosis-1 complained of right gonalgia in December 2001. Physical examination revealed a huge tumor in the right lower leg without signs of inflammation. Laboratory findings were unremarkable. Radiographic examination disclosed the presence of osteoarthropathy in the right knee joint. In contrast, radiologic findings of the right foot and ankle were compatible with neuropathic arthropathy. Further investigations could not reveal abnormal findings in the nervous system. To improve patient's quality of life, partial resection of the tumor was performed. The resected tissues were compatible with neurofibromatosis without malignant transformation. The patient newly noticed pains in the right ankle and tarsal joints one year after the operation. Restricted mobility and insufficient blood supply in the right knee arising from the huge tumor might accelerate development of osteoarthropathy through malnutrition of the chondrocytes. Because the patient did not experience the arthralgia before the operation, the tumor might damage the peripheral nerves unabling to receive afferent signals from such joints resulting in neuropathic arthropathy.The damaged peripheral nerves might be contributory to developing or accelerating neuropathic arthropathy.

We evaluated the vulnerability of central nervous system (CNS) in patients with systemic lupus erythematosus (SLE) using exploratory eye movement analysis and random number generation (RNG), and compared the tests in evaluating CNS vulnerability. Nineteen patients received the tests more than a month after SLE onset in nonpsychotic status. Exploratory eye movements were analyzed using an eye-mark recorder that detects corneal reflection of infrared light, and numbers of eye fixations were counted to calculate responsive search score (RSS). Using digits 0 through 9, 100 numbers were vocally generated at a random fashion. “Seriality score” was calculated from the recorded 100 numbers. RSS of SLE patients was similar to that of normal individuals, irrespective of neuropsychiatric lupus history. Seriality score of patients having a history of neuropsychiatric lupus was higher than that of never having it (p

Proton-pump inhibitors have been reported to influence the human immune system, we therefore evaluated the effect of lansoprazole, a proton-pump inhibitor, on humoral immunity. Patients with gastric ulcer received lansoprazole 30 mg/day for 8 weeks, and serum immunoglobulins were evaluated before and upon completion of the treatment. There were 79 patients with gastric ulcer; 51 were H. pylori-infected and 28 were H. pylori-uninfected. Eighteen patients positive for H. pylori were receiving at least one non-steroidal anti-inflammatory drug, and 12 patients negative for H. pylori received one non-steroidal anti-inflammatory drug. H. pylori-infected patients showed significant increases in serum immunoglobulins G and M 8 weeks after the start of lansoprazole treatment ( P

A 23-year-old Japanese woman with a fever and generalized skin eruptions was referred to our hospital in July 1999. At admission, her temperature was 38.9 degrees C, and she had fluctuating symptoms including erythema of the extremities, conjunctival hyperemia, strawberry tongue, and generalized skin eruptions, but lymphadenopathy was not verified. An initially elevated urine leukocyte count (more than 100 per high power field) later returned to normal range without antibiotic therapy. Adult Kawasaki disease was diagnosed on the basis of the above symptomology. Echocardiograph showed transient effusion in the pericardium. Using the Harada scoring system for treatment of Kawasaki disease, we gave the patient aspirin and did not administer intravenous immunoglobulin. The clinical course was uneventful, and on the day of discharge (day 22 after onset), the laboratory test results were nearly normal. Laboratory test results were negative for both Epstein-Barr virus and group A Streptococcus.

A 62-year-old Japanese woman with RA received an eradication therapy against Helicobacter pylori in November 1999. Eight weeks later, successful eradication was confirmed by negative results for rapid urease test, pathologic findings, and a fall in anti-H. pylori IgG antibody titer. During the course, parameters for RA activity were exacerbated: C-reactive protein 1.1-4.2 mg/dL, rheumatoid arthritis precipitation antigen 2560-5120 dils., erythrocyte sedimentation rate 52-123 mm/h, and complements CH50 50 to over 60 U/mL. Lansbury index increased from 70% to 105%. Two more weeks later, the patient noticed right shoulder pain. She also complained of bilateral gonalgia two months later, and physical examination revealed increased fluid in the knee joints. Prednisolone was required to control the disease activity. The results of this case suggested that RA patients might experience a deleterious effect on the disease activity following H. pylori eradication possibly through disruption of the established oral tolerance against stress protein such as mycobacterial heat shock protein 65.

Objective To address the presence of post-Q fever fatigue syndrome (post-QFS) in Japan, and to evaluate the efficacy of minocycline for this condition. Patients and Methods In 20 Coxiella burnetii (C. burnetii) seropositive patients with persistent nonspecific symptoms including general fatigue, low-grade fever, myalgia and arthralgia, changes in subjective symptoms, C. burnetii antibody titers and C. burnetii DNA were evaluated after antibiotic treatment. Results After treatment mainly with minocycline (100 mg/day for 3 months), the clinical picture improved in all 20 patients as evidenced by decreases in body temperature (13/17), general fatigue (20/20) and headache (9/12). The mean performance status (PS) score improved from 5.0 to 1.8 (p

Objective. Regarding the interaction of Helicobacter pylori and non-steroidal anti-inflammatory drugs (NSAIDs), we cannot accept unanimous conclusions in inducing gastric ulcer. We therefore evaluated the role of Helicobacter pylori and NSAIDs in inducing gastric ulcer. Methods. Dyspeptic patients receiving NSAIDs underwent endoscopic examination. Gastric ulcer formation and H. pylori status were investigated. Biopsy specimens from the antrum and lower body of the stomach were prepared for the rapid urease test and pathological evaluation. Anti-H. pylori antibody was measured by enzyme-linked immunosorbent assay. Results. Two hundred and twenty-six patients receiving NSAIDs (220 chronic and six on-demand users) underwent gastrofibrescopic examination. There were 110 patients with gastric ulcer and 111 non-ulcer patients with gastritis. The remaining five patients had neither. NSAID users with gastric ulcer showed a low prevalence of H. pylori compared with those without them w55u110 (50.0%) vs 79u111 (71.2%), P < 0.01x. The same tendency was seen when patients receiving low-dose aspirin and those with rheumatoid arthritis were analysed separately w13u29 (44.8%) vs 50u62 (80.6%), P < 0.01, and 11u33 (33.3%) vs 16u26 (61.5%), P < 0.06 with Yates’ correction, respectivelyx. Conclusion. Helicobacter pylori infection appeared to be a risk factor for developing gastritis, but we found no evidence that it increases gastric ulcer formation in NSAID users with dyspepsia.

We report two patients with scleroderma, 73-year-old female and 67-year-old female, who developed anti neutrophil cytoplasmic autoantibody (ANCA) associated rapid progressive glomerulonephritis (RPGN). Both patients have had a long history of scleroderma (23 and 14 years, respectively) when ANCA-associated glomerulonephritis occurred. In the first patient, scleroderma was localized in both fingers. She has been followed-up as CREST syndrome rather than systemic sclerosis. The complaints on admission were leg edema and left chest pain in the first patient, and a pyrexia and dyspnea in the second patient. Both patients showed pulmonary manifestation (pleural effusion in the first patient, interstitial pneumonia and alveolar hemorrhage in the second patient, respectively) and rapid progressive glomerulonephritis. Both patients died in spite of corticosteroid therapy. Autopsy findings in the second patient demonstrated crescentic glomerulonephritis and alveolar hemorrhage. Our cases demonstrated that MPO-ANCA associated glomerulonephritis could be associated with limited scleroderma as well as systemic scleroderma. In these condition, the prognosis will be poor if scleroderma seemed to be stable.

The objective of this study was to assess the effect of beraprost sodium, an oral prostacyclin analogue, on pulmonary function in patients with systemic sclerosis. Seventeen patients, with systemic sclerosis and predicted percent values of carbon monoxide diffusion capacity (%DLCO) of less than 95, received beraprost sodium for at least 12 months. Conventional testing for pulmonary function was performed at 12-month intervals and changes were evaluated with special reference to DLCO. Twelve patients completed the treatment. Nine patients showed improvement in DLCO (12.1 +/- 2.3 to 15.5 +/- 4.4 ml/min/mmHg, P0.006) and 10 patients showed an increase in %DLCO (66.6 +/- 11.9 to 87.7 +/- 23.2%, P0.004). Total lung capacity, vital capacity and forced expiratory volume remained unchanged. This study showed that DLCO levels in patients with systemic sclerosis improved after the administration of beraprost sodium, probably due to the decrease in pulmonary vascular resistance accompanied by increased cardiac output.

The psychiatric and cognitive condition of a patient with lupus psychosis was evaluated. Using a device that detects the corneal reflection of infrared light, the patterns of eye tracking movements were recorded before the onset of lupus psychosis, after remission, and again 1 year later. Electroencephalographic findings and cerebrospinal fluid levels of both interferon alpha and interleukin-6 were also obtained longitudinally. Electroencephalographic findings and clinical signs were correlated to the levels of interferon alpha in cerebrospinal fluid. Analysis of exploratory eye movements revealed marked decreases in the number of eye fixation, mean eye-scanning length and total eye-scanning length. Even though the lupus psychosis resolved and the electroencephalographic findings became normal, the eye movement patterns showed remaining deterioration. It was concluded that analysis of exploratory eye movements in patients with systemic lupus erythematosus may be useful in diagnosing lupus psychosis, and may also present a diagnostic clue to subclinical lupus psychosis.

A 43-year-old Japanese woman was referred to our hospital in 1997 because of Raynaud's phenomenon. Systemic lupus erythematosus was diagnosed on the basis of the presence of antinuclear antibody (1:1,280), anti-DNA antibody (1:640), anti-Sm antibody, antiphospholipid antibody, lymphopenia, and proteinuria. She developed pulmonary fibrosis in 1999 and pulmonary hypertension in 2001. In October 2002, a 24-hr continuous infusion of epoprostenol was started. Dyspnea, Raynaud's phenomenon, and pulmonary hypertension improved with low-dose epoprostenol (3.0 to 4.0 ng kg(-1) min(-1)). The patient could not tolerate larger doses of epoprostenol so 4.0 ng kg(-1) min(-1) was selected as the maintenance dose. The clinical course was uneventful at this dosage. It appears that pulmonary hypertension can be controlled with low-dose epoprostenol such as 3.0 to 4.0 ng kg(-1) min(-1) in some rheumatic patients.

The clinical use of antithymocyte globulin is rarely reported in patients with rheumatic diseases. We describe the use of this agent in a patient with systemic lupus erythematosus who concomitantly developed severe pancytopenia. High-dose methylprednisolone therapy had been unsuccessful in controlling either the disease exacerbation or the pancytopenia. Antithymocyte globulin and cyclosporin A were therefore administered to achieve immunosuppression. The exacerbation of disease activity was gradually lessened, except for persistent thrombocytopenia and anaemia. Severe and persistent immunosuppression, however, led to a fatal brain abscess. The combined use of both antithymocyte globulin and cyclosporin A induced potent immunosuppression, and should be confined to selected patients with systemic lupus erythematosus, and administered under detailed monitoring.

We present the unusual case of 16-year-old girl who developed intractable convulsions five days after the onset of a cold. Meningeal signs, lymphopenia, proteinuria, and lupus anticoagulant were also present. Treatment with anticonvulsants, antituberculous agents, and adenine arabinoside were ineffective. The initiation of methylprednisolone pulse therapy immediately resolved convulsions and fever. The diagnosis, suggested by the clinical course and the marked improvement of the meningoencephalitis by pulse therapy, was an encephalitic form of acute disseminated encephalomyelitis. Clinical and laboratory findings indicated that an immune disorder may have triggered an abnormal response to a viral infection leading to this patient's neurologic disorder.

A 68-year-old woman had been complained of xerostomia since she was 30 years old. Further symptoms of polyuria, polyposia and insomnia had been developed since she was 35 years old. The biopsy material from a minor salivary gland demonstrated the infiltration of lymphocytes into mesenchyme which was compatible with Sjogren's syndrome. She admitted to our hospital because of myalgia in bilateral gastrocnemius and petechiae in both lower extremities in addition to the complaints described above. Complete blood cell counts on admission revealed hemoglobin 9.7 g/dl, platelet count 12.5 x 10(4)/microliters, and white blood cell count 3,300/microliters. Marked polyuria, polyposia (more than 5,000 ml/day, respectively) and low urine gravity (1.005) were observed, although the serum creatinine level showed normal value. Serologic examination showed that the elevation of total serum protein concentration (9.5 g/dl) with marked elevation of serum IgG level (6,190 mg/dl). Her immunoglobulins contained cryoglobulin (cryocrit 20%), and immunoelectrophoresis demonstrated the existence of IgG-kappa monoclonal protein. A positive anti-nuclear antibody at 1:320 dilution, a positive rheumatoid factor and a positive antibody to SS-A (Ro) were also observed. The serial studies of blood gas analysis could not demonstrated the presence of metabolic acidosis. Together with the result of elevated plasma antidiuretic hormone level and results of vasopressin test, Fishberg's concentrating test and the tests of the overload of NH4Cl or bicarbonate, she was diagnosed Sjogren's syndrome with both diabetes insipidus and subclinical renal tubular acidosis. She was initially medicated with prednisolone (40 mg/day, orally), then she was given six courses of intravenous cyclophosphamide (750 mg/body/month).(ABSTRACT TRUNCATED AT 250 WORDS)

We estimated the concentration of soluble IL-2R (sIL-2R) in the serum of patients with systemic lupus erythematosus (SLE) and examined the relationship between the serum levels of sIL-2R and clinical features or laboratory data. We found that elevated levels of sIL-2R were present in the serum of SLE patients with discoid rash, and sIL-2R concentrations were correlated with the soluble CD4 and soluble CD8 concentrations but not with classical serological marker, anti-DNA antibody or complement titer.

A 41-year-old patient with chronic myelogenous leukemia in the accelerated phase was treated with mitoxantrone. She developed pyrexia 7 days after receiving the third administration of mitoxantrone. After 3 more days, she experienced dry cough and dyspnea. Bilateral fine crackles were audible, but no signs of heart failure were found. A chest X-ray film revealed diffuse reticulogranular infiltrates bilaterally. An increase in the prednisolone dosage led to an improvement. Specimens of the bronchoalveolar lavage revealed an increase in CD4–/CD8– lymphocytes. The peripheral lymphocytes also expressed neither CD4 nor CD8. Specimens of a transbronchial lung biopsy disclosed thickening of the alveolar wall with infiltration of lymphoid cells.

We examined the effect of famotidine, a histamine-type 2 receptor antagonist, on the immunocompetent cells. The number of DR(+) cells were significantly decreased in patients with systemic lupus erythematosus (P

A 34-year-old Japanese woman developed spiking fever, splenomegaly, arthritis, neutrophilia, hyperferritinaemia (22517 ng/ml), elevated C-reactive protein (9.1 mg/ml) and severe thrombocytopenia (1.7 x 10(4)/microl). The patient had depressed antithrombin III activity and abnormally high concentrations of both fibrin degradation products and thrombin-antithrombin complexes. This condition was resistant to high-dose prednisolone therapy (120 mg/day) and non-steroidal anti-inflammatory drugs. We initiated oral methotrexate therapy (7.5 mg/week, orally) with a favourable outcome. The patient's spiking fever subsided on the first day of methotrexate administration. Elevated levels of ferritin and C-reactive protein in the sera rapidly normalised. Methotrexate rapidly improved the disease state which suggested that methotrexate act via modulation of cytokine production or secretion.
