Destructive osteomyelitis involving Parvimonas micra and Campylobacter rectus.

We present a rare case of destructive osteomyelitis of the sternum caused by Parvimonas micra and Campylobacter rectus A previously healthy female patient in her 40s presented to the emergency department due to a spontaneous rupture of an abscess located to the chest wall. Imaging confirmed abscess formation with osteomyelitis of the sternum. Emergent surgical debridement was performed, blood and bone cultures were taken and the patient received antibiotic treatment. Cultures of the bone and deep tissue revealed infection with Parvimonas micra and Campylobacter rectus, both being members of the oral flora and associated with chronic periodontitis. Receiving targeted antibiotic treatment, our patient made a quick recovery. After treatment of the osteomyelitis, our patient was referred to the dentist where chronic periodontitis could be confirmed. Invasive infections with Parvimonas micra and Campylobacter rectus are rare. Investigation of a dental origin is crucial to prevent recurrent infections.

Risk for adverse pregnancy outcome in axial spondyloarthritis and rheumatoid arthritis: disease activity matters.

OBJECTIVE: To analyse pregnancy outcome and delivery mode in patients with RA and axial spondyloarthritis (axSpA) in relation to disease activity and anti-rheumatic drugs. METHODS: Patients with RA and axSpA were compared with age-matched healthy controls (HCs) with respect to pregnancy outcome and delivery mode. Disease activity (DAS28, ASDAS, CRP) and medication use of patients was assessed once at each trimester. ORs with 95% CI were calculated with univariate and multivariate regression models. RESULTS: We analysed 244 pregnancies, of which 96 occurred in patients with RA, 78 in patients with axSpA and 70 in HCs. The adjusted analysis showed that pregnant women with RA and axSpA had a higher risk of pregnancy complications (gestational diabetes, preeclampsia, infection, preterm premature rupture of membranes), small for gestational age infants and preterm deliveries (all P < 0.05). Active disease was a predictor for preterm delivery in both RA [odds ratio (OR) = 3.9, 95% CI: 1.25, 12.15] and axSpA (OR = 13.8, 95% CI: 1.33, 143.94). Regarding delivery mode, most patients had vaginal deliveries. However, women with RA revealed an increased risk of caesarean section compared with HC (P < 0.05), which was not seen in patients with axSpA. CONCLUSION: Our findings show that disease activity of RA and axSpA during pregnancy influences pregnancy outcome. To allow for successful pregnancy a treatment strategy that targets inactive disease beyond conception should be followed.

Risk factors for flare and treatment of disease flares during pregnancy in rheumatoid arthritis and axial spondyloarthritis patients.

BACKGROUND: During pregnancy, patients with rheumatoid arthritis (RA) and axial spondyloarthritis (axSpA) can experience active disease, which might be influenced by adjustment of treatment around conception. The aim of this study was to identify possible risk factors of disease flares during pregnancy and to evaluate the effect of treatment in pregnant patients experiencing a flare. METHODS: Pregnant patients with RA and axSpA were prospectively followed before, during, and after pregnancy. Disease activity and flares of disease activity were analyzed in regard to medication. RESULTS: Among 136 pregnant patients, disease flares during pregnancy occurred in 29% of patients with RA and in 25% of patients with axSpA. In both diseases, active disease and tumor necrosis factor inhibitor (TNFi) discontinuation in early pregnancy were identified as risk factors for disease flares during pregnancy. Of 75 patients with RA, 15 patients were on TNFi and discontinued the treatment at the time of the positive pregnancy test. After stopping TNFi, disease activity increased, which was reflected by peaking C-reactive protein levels at the first trimester. The relative risk of flare in patients with RA stopping TNFi was 3.33 (95% CI 1.8-6.1). Initiation of TNFi or glucocorticosteroid (GC) treatment in 60% of these patients resulted in disease improvement at the second and third trimesters. In comparison, patients with RA without TNFi in the preconception period, most of whom had used pregnancy-compatible antirheumatic drugs, showed mild and stable disease activity before and during pregnancy. Of 61 patients with axSpA, 24 patients were on TNFi and discontinued the treatment at the time of the positive pregnancy test. In patients with axSpA stopping TNFi, a disease aggravation at the second trimester could be observed. The relative risk of flare in this group was 3.08 (95% CI 1.2-7.9). In spite of initiated TNFi or GC treatment in 62.5% of these patients, disease activity remained elevated throughout pregnancy. Patients with axSpA without TNFi in the preconception period showed persistent high disease activity from prepregnancy until the postpartum period. CONCLUSIONS: On the basis of a risk-benefit analysis, to stabilize disease activity and to prevent a flare during pregnancy in patients with RA and axSpA, tailored medication including TNF inhibitors should be considered beyond conception.

[McKittrick-Wheelock syndrome]. / Syndroom van McKittrick-Wheelock.

BACKGROUND: The McKittrick-Wheelock syndrome is rare and is characterized by hypersecretion of fluids and electrolytes by a large rectal villous adenoma. Untreated disease may cause fatal renal failure or arrhythmia. We present 2 cases with different symptoms. CASE DESCRIPTIONS: An 83-year-old female with long-standing renal failure of unknown origin was admitted due to dehydration with recurrent collapse and electrolyte imbalance. Colonoscopy was performed because of persistent diarrhoea, which revealed an extensive rectal adenoma. After endoscopic mucosal resection, electrolyte values normalized entirely. A 66-year-old male presented with malaise, weight loss and severe renal failure. A giant rectal adenoma was found. After endoscopic mucosal resection, the electrolyte imbalance disappeared and renal function normalized. A fibrotic remnant required surgical removal and revealed submucosally invasive carcinoma. CONCLUSION: In rare cases, renal failure and electrolyte imbalance may be caused by large rectal adenomas.
