Aseptic meningitis followed by mononeuritis multiplex in a patient with primary Sjögren's syndrome.

A 38-year-old woman was admitted to hospital because of fever and headache. Increased cerebrospinal cell count and protein without evidence of infection led to a diagnosis of aseptic meningitis. Although she improved with acyclovir and glyceol, she experienced left forearm pain and sensory disturbance with drop fingers. Poor derivation of compound muscle action potentials in the left radial nerve was observed, leading to a diagnosis of mononeuritis multiplex with sensorimotor neuropathy. Because the patient had primary Sjögren's syndrome with anti-Ro/SS-A antibody and salivary gland hypofunction, treatment with methylprednisolone, intravenous immunoglobulin, and intravenous cyclophosphamide was followed by oral glucocorticoid therapy. After these intensive therapies, her drop fingers gradually improved, although sensory disturbance remained. In conclusion, we report a case of aseptic meningitis and subsequent mononeuritis multiplex that was successfully treated with intensive immunotherapy in a patient with primary Sjögren's syndrome.

Risk factors associated with relapse after methotrexate dose reduction in patients with rheumatoid arthritis receiving golimumab and methotrexate combination therapy.

AIM: To identify risk factors for relapse after methotrexate (MTX) dose reduction in rheumatoid arthritis (RA) patients receiving golimumab (GLM)/MTX combination therapy. METHOD: Data on RA patients ≥20 years old receiving GLM (50 mg) + MTX for ≥6 months were retrospectively collected. MTX dose reduction was defined as a reduction of ≥12 mg from the total dose within 12 weeks of the maximum dose (≥1 mg/wk average). Relapse was defined as Disease Activity Score in 28 joints using C-reactive protein level (DAS28-CRP) score ≥3.2 or sustained (≥ twice) increase of ≥0.6 from baseline. RESULTS: A total of 304 eligible patients were included. Among the MTX-reduction group (n = 125), 16.8% of patients relapsed. Age, duration from diagnosis to the initiation of GLM, baseline MTX dose, and DAS28-CRP were comparable between relapse and no-relapse groups. The adjusted odds ratio (aOR) of relapse after MTX reduction was 4.37 (95% CI 1.16-16.38, P = 0.03) for prior use of non-steroidal anti-inflammatory drugs (NSAIDs), and the aORs for cardiovascular disease (CVD), gastrointestinal disease and liver disease were 2.36, 2.28, and 3.03, respectively. Compared to the non-reduction group, the MTX-reduction group had a higher proportion of patients with CVD (17.6% vs 7.3%, P = 0.02) and a lower proportion of prior use of biologic disease-modifying antirheumatic drugs (11.2% vs. 24.0%, P = 0.0076). CONCLUSION: Attention should be given to RA patients with history of CVD, gastrointestinal disease, liver disease, or prior NSAIDs-use when considering MTX dose reduction to ensure benefits outweigh the risks of relapse.

Successful treatment for eosinophilic granulomatosis with polyangiitis causing severe myocarditis followed by cardiac magnetic resonance.

A 38-year-old woman had a history of asthma for 20 years. Bullous lesions had appeared on her left side of the back. Two months before admission, the biopsy revealed eosinophilic cellulitis. One month later, she experienced numbness in both legs. She was admitted to our hospital for emergency treatment due to chest pain and loss of consciousness. Emergency coronary angiography revealed triple-vessel vasospasm. She had cardiac arrest for 4 min during the examination. We suspected eosinophilic granulomatosis with polyangiitis due to pulmonary infiltrate, eosinophilia, and a history of illness. We, therefore, started methylprednisolone pulse therapy. Although her condition and laboratory findings improved, cardiac magnetic resonance (CMR) imaging performed on day 16 showed myocardial oedema and myocardial fibrosis on late gadolinium enhancement. Coronary angiography on day 35 revealed no spasm, and myocardial biopsy showed the absence of vasculitis. There was no improvement in myocardial oedema. CMR showed enlargement of late gadolinium enhancement and formation of a ventricular aneurysm. As myocarditis did not improve sufficiently, five courses of intravenous cyclophosphamide pulse therapy were administered. CMR on day 152 showed the disappearance of myocardial oedema. We report a unique case of successful treatment of severe myocarditis and the usefulness of follow-up CMR.

Successful early introduction of mepolizumab for peripheral neuropathy with a peripheral circulatory disorder in a patient with myeloperoxidase anti-neutrophil cytoplasmic antibody-negative eosinophilic granulomatosis with polyangiitis.

A 26-year-old woman presented with abdominal pain, diarrhoea, vomiting, fever, and progressive paralysis in the lower limbs. She had a history of bronchial asthma and experienced sinusitis, progressive peripheral neuropathy, polyarthritis, and leukocytosis with prominent eosinophilia. The patient was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA). Abdominal pain was considered to be an ischaemic enteritis associated with EGPA. She was administered 1,000 mg/day of methylprednisolone for 3 days and intravenous immunoglobulin (400 mg/kg/day of γ-globulin for 5 days) followed by 50 mg (1 mg/kg)/day of oral prednisolone due to rapidly progressing peripheral neuropathy. Her symptoms temporarily improved; however, peripheral neuropathy recurred after a week, and the eosinophil count increased. Eighteen days after following the resumed treatment, 300 mg of mepolizumab, a humanised monoclonal antibody, was administered. Subjective symptoms, nerve conduction velocity, and skin perfusion pressure (an index of peripheral circulation in the lower extremities) improved after 4 weeks. Although mepolizumab has been approved for EGPA, there is no evidence of its efficacy against peripheral neuropathy. Early introduction of mepolizumab may contribute to an the early improved progressive peripheral neuropathy with eosinophilia.

High incidence of colonic perforation during colonoscopy in hemodialysis patients with end-stage renal disease.

BACKGROUND & AIMS: Colonic perforation is a rare but life-threatening complication of colonoscopy. We evaluated the incidence of colonic perforation that resulted from colonoscopy in patients who underwent hemodialysis compared with those who did not have this procedure (controls). METHODS: Data from a total of 15,098 consecutive patients who underwent colonoscopy from January 2001 to December 2008 in Nagoya Kyoritsu Hospital were analyzed retrospectively. Patients were divided into 2 groups: 1106 hemodialysis patients and 13,992 controls. The incidence of colonic perforation, patient characteristics, and locations of perforation during colonoscopy were compared between the 2 groups. Furthermore, perforated mucosa samples from colons were examined by pathology analysis. RESULTS: Colonic perforations occurred in 5 hemodialysis patients and 3 controls. The incidence of colonic perforation was markedly higher in the hemodialysis group than in the control group (0.45% vs 0.02%; odds ratio, 21.17; 95% confidence interval, 5.05-88.73; P < .0001). Even after multivariate analysis of age, sex, and patients who received polypectomies, hemodialysis still was associated independently with the risk of colonic perforation during colonoscopy (odds ratio, 19.91; 95% confidence interval, 4.61-85.93; P < .0001). Pathologic examination of perforated mucosa was performed in 3 hemodialysis patients and 3 control patients. beta2-microglobulin deposition was observed in all 3 hemodialysis patients. In contrast, beta2-microglobulin deposition was not detected in control patients. CONCLUSIONS: There is a higher risk of colonic perforation during colonoscopy among patients who received hemodialysis compared with those who did not. beta2-microglobulin deposition might have a role in perforation in patients who receive hemodialysis.
