Lupus mesenteric vasculitis (LMV) is a unique clinical entity found in patients who present with gastrointestinal manifestations of systemic lupus erythematosus, and is the main cause of acute abdominal pain in these patients. LMV usually presents as acute abdominal pain with sudden onset, severe intensity and diffuse localization. Other causes of abdominal pain, such as acute gastroenteritis, peptic ulcers, acute pancreatitis, peritonitis, and other reasons for abdominal surgery should be ruled out. Prompt and accurate diagnosis of LMV is critical to ensure implementation of appropriate immunosuppressive therapy and avoidance of unnecessary surgical intervention. The pathology of LMV comprises immune-complex deposition and complement activation, with subsequent submucosal edema, leukocytoclastic vasculitis and thrombus formation; most of these changes are confined to small mesenteric vessels. Abdominal CT is the most useful tool for diagnosing LMV, which is characterized by the presence of target signs, comb signs, and other associated findings. The presence of autoantibodies against phospholipids and endothelial cells might provide information about the likelihood of recurrence of LMV. Immediate, high-dose, intravenous steroid therapy can lead to a favorable outcome and prevent serious complications such as bowel ischemia, necrosis and perforation.
Circulating IL-34 levels in RA correlated with autoantibody production. Further investigations of localized and systemic effects of IL-34 are warranted to elucidate RA pathogenesis.
Poor sleep quality is the common independent risk factor for poor HRQoL in both middle-aged SLE patients with fibromyalgia and without fibromyalgia. Sleep quality improvement may improve HRQoL in female SLE patients, even in those without fibromyalgia.
The purpose of this study was to evaluate the relationships between the prevalence of depression and dental pain using a well characterised, nationally representative, population-based study. This study analysed data from the 2012 Korea National Health and Nutrition Examination Survey (n = 4886). Oral health status was assessed using the oral health questionnaire, and oral examination was performed by trained dentists. Depression was defined as the participant having been diagnosed as depression during the previous year. Logistic regression was applied to estimate adjusted odds ratios (AOR) and 95% confidence intervals (CI), controlling for a range of covariates. Results demonstrated that participants included in 'root canal treatment is necessary' showed higher prevalence of self-reported dental pain; in particular, participants with depression presented more dental pain than those without depression. After adjusting for sociodemographic factors, self-reported dental pain increased in participants with depression. The AOR (95% CI) for having self-reported dental pain was 1·58 (1·08-2·33) in dentists' diagnosis of no dental pain/depression group, 1·62 (1·32-1·98) in dentists' diagnosis of dental pain/no depression group and 2·84 (1·10-7·37) in dentists' diagnosis of dental pain/depression group. It was concluded that depression was associated with dental pain after adjustment for potential confounders in Korean adults. Thus, dentists should consider the possible presence of psychopathology when treating patients with dental pain.
A 55 yr-old man presented with progressive muscle weakness and oliguria for 5days. Laboratory findings suggested rhabdomyolysis complicated with acute renal failure. A diagnosis of polymyositis was based upon the proximal muscle weakness on both upper and lower limbs, elevated muscle enzyme levels, muscle biopsy findings and the needle electromyography findings. The muscle biopsy showed extensive muscle necrosis and calcification. Investigations for underlying malignancy demonstrated hepatocellular carcinoma. The patient was managed with hemodialysis and high dose prednisolone. His renal function was fully recovered and his muscle power did improve slightly, but he died of a rupture of the hepatic tumor. In our view, this is an interesting case in that the hepatocellular carcinoma was associated with polymyositis and fulminant rhabdomyolysis-induced acute renal failure requiring hemodialysis.
ObjectiveWe aimed to evaluate the clinical outcomes and safety of biologic and targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs) and to identify predictors of treatment responses to b/tsDMARDs in elderly patients with rheumatoid arthritis (RA).
MethodsData from the nationwide cohort of elderly (≥ 65 years) patients enrolled in the KOBIO Registry were analysed. Clinical outcomes were assessed, including changes in the Simplified Disease Activity Index, after treatment. Adverse events and reasons for drug discontinuation were assessed. Multivariable logistic regression analyses were performed to determine which baseline variables affected treatment responses and adverse events (AE).
ResultsElderly patients treated with b/tsDMARDs (n=355) or conventional synthetic DMARDs (csDMARDs) (n=104) were included. The median age was 70 years and 77% were female. After 1 year, 63% of patients in the b/tsDMARD group and 68% in the csDMARD group achieved remission or low disease activity (LDA). Overall, 27% of patients in the b/tsDMARDs group and 24% in the csDMARDs group experienced AE. A total of 43.4% of patients on b/tsDMARDs discontinued therapy due to lack of effectiveness (27%), AE (34%), or other reasons (35%). The estimated median retention of b/tsDMARDs was 2.5 years. Male sex and non-exposure to tobacco at baseline were independent factors associated with achieving remission or LDA after 1 year. Interstitial lung disease (ILD) was the most prominent comorbidity associated with AE.
ConclusionTreatment with b/tsDMARDs is effective and well tolerated in elderly patients with RA; nonetheless, ILD is a key comorbidity that should be monitored carefully.
