- Objective. To evaluate the consultation rates of selected comorbidities in patients with antineutrophil cytoplasmic antibody-associated vasculitis (AAV) compared with the general population in southern Sweden. Methods. We used data from a population-based cohort of patients with AAV diagnosed between 1998 and 2010 in Southern Sweden (701,000 inhabitants). For each patient we identified 4 reference subjects randomly sampled from the general population and matched for year of birth, sex, area of residence, and index year. Using the population-based Skåne Healthcare Register, we identified relevant diagnostic codes, registered between 1998 and 2011, for selected comorbidities assigned after the date of diagnosis of AAV or the index date for the reference subjects. We calculated rate ratios for comorbidities (AAV:reference subjects). Results. There were 186 patients with AAV (95 women, mean age 64.5 yrs) and 744 reference persons included in the analysis. The highest rate ratios (AAV:reference) were obtained for osteoporosis (4.6, 95% CI 3.0-7.0), followed by venous thromboembolism (4.0, 95% CI 1.9-8.3), thyroid diseases (2.1, 95% CI 1.3-3.3), and diabetes mellitus (2.0, 95% CI 1.3-2.9). For ischemic heart disease, the rate ratio of 1.5 (95% CI 1.0-2.3) did not reach statistical significance. No statistically significant differences were found for cerebrovascular accidents. Conclusion. AAV is associated with increased consultation rates of several comorbidities including osteoporosis and thromboembolic and endocrine disorders. Comorbid conditions should be taken into consideration when planning and providing care for patients with AAV.

- Objective. Involvement of the gastrointestinal (GI) tract is a rare complication of granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). The aim was to describe frequency, diagnosis, treatment, and outcome of GI disease in a large series of patients in a single center. Methods. A database that includes all patients with GPA and MPA diagnosed since 1997 in a defined area of southeastern Sweden as well as prevalent older cases and tertiary referral patients was screened for patients with GI disease. Data were retrieved from the patients medical records, and GI manifestations of vasculitis were defined as proposed by Pagnoux, et al in 2005. Results. Fourteen (6.5%) of 216 consecutive patients with GPA/MPA had GI manifestations. Abdominal pain and GI bleeding were the most common symptoms. Radiology was important for detection of GI disease, while endoscopy failed to support the diagnosis in many patients. Because of perforation, 5 patients underwent hemicolectomy or small intestine resection. Primary anastomosis was created in 2/5 and enterostomy in 3/5 patients. One patient had a hemicolectomy because of lower GI bleeding. One sigmoid abscess was treated with drainage, and 1 intraabdominal bleeding condition with arterial coiling. Two patients died from GI disease. GPA and MPA patients with and without GI disease exhibited a similar overall survival. Conclusion. GI disease was found in 6.5% among 216 patients with GPA or MPA. Surgery was judged necessary only in cases with GI perforation or severe bleeding. Multidisciplinary engagement is strongly recommended.

- OBJECTIVE:Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is usually differentiated based on clinical phenotypes, but recent data indicate that myeloperoxidase (MPO)-AAV is genetically distinct from proteinase 3 (PR3)-AAV. We reviewed a population-based cohort of AAV, focusing on differences in clinical and laboratory characteristics and to compare renal outcome between MPO-ANCA and PR3-ANCA nephritis.METHODS:All new cases of AAV diagnosed between 1997 and 2009 in a geographically defined area in southern Sweden were retrieved using a validated search algorithm. Data were collected from time of diagnosis and end of followup. Renal and patient survival were analyzed according to ANCA serotype.RESULTS:During the study period, 201 patients were diagnosed with AAV, 98 tested positive for PR3-ANCA, and 85 for MPO-ANCA. Patients with PR3-ANCA were younger, had significantly higher inflammatory activity, and had a larger number of organs involved at diagnosis, but nephritis was more prevalent among patients with MPO-associated (72/85; 85%) versus PR3-associated disease (67/98, 68%). When comparing only patients with ANCA-associated nephritis, those with MPO-ANCA were more likely to develop endstage renal disease (n = 27, 38%) than those with PR3-ANCA (n = 10, 15%), p = 0.003. The risk remained significantly elevated after adjusting for sex, age, and s-creatinine level at diagnosis (HR 2.64; 95% CI 1.25-5.58; p = 0.003). There were no significant differences in mortality rates between the 2 groups.CONCLUSION:The outcome in this population-based cohort indicates that among AAV patients with nephritis, renal prognosis is better in the PR3-ANCA group, even after adjustment for sex, age, and renal function at diagnosis.

Severe infection in antineutrophil cytoplasmic antibody-associated vasculitis

- Objective. To compare the rate of severe infections after the onset of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) with the rate in the background population, and to identify predictors of severe infections among patients with AAV. Methods. The study cohort was 186 patients with AAV diagnosed from 1998 to 2010, consisting of all known cases in a defined population in southern Sweden. For each patient, 4 age- and sex-matched reference subjects were randomly chosen from the background population. Using the Skåne Healthcare Register, all International Classification of Diseases codes of infections assigned from 1998 to 2011 were identified. Severe infections were defined as infectious episodes requiring hospitalization. Rate ratios were calculated by dividing the rate in AAV by the rate among the reference subjects. Results. The rate ratio for all severe infections was 4.53 (95% CI 3.39-6.00). The highest rate ratios were found for upper respiratory tract: 8.88 (3.54-25.9), Clostridium difficile: 5.35 (1.54-23.8), nonspecific septicemia 4.55 (1.60-13.8), and skin 5.35 (1.69-19.8). Of the severe infections, 38.4% occurred within 6 months of diagnosis, 30.2% from 7-24 months, and 31.4% after 24 months. High serum creatinine and older age at diagnosis were associated with severe infection (p < 0.001). Of those with severe infection, 46.5% died during followup compared to 26% of patients without severe infection (p = 0.004). Conclusion. Patients with AAV have markedly higher rates of severe infection compared with the background population, especially patients with older age and impaired renal function. The risk of severe infection is particularly high in the first 6 months following the diagnosis of vasculitis.

- Objective. Age is a risk factor for organ damage, adverse events, and mortality in microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA). However, the relationship between treatment and damage, hospitalizations, and causes of death in elderly patients is largely unknown. Methods. Consecutive patients from Sweden, the United Kingdom, and the Czech Republic diagnosed between 1997 and 2013 were included. Inclusion criteria were a diagnosis of MPA or GPA and age 75 years or more at diagnosis. Treatment with cyclophosphamide (CYC), rituximab (RTX), and corticosteroids the first 3 months was registered. Outcomes up to 2 years from diagnosis included Vasculitis Damage Index (VDI), hospitalization, and cause of death. Results. Treatment data were available for 167 of 202 patients. At 2 years, 4% had no items of damage. There was a positive association between VDI score at 2 years and Birmingham Vasculitis Activity Score at onset, and a negative association with treatment using CYC or RTX. Intravenous methylprednisolone dose was associated with treatment-related damage. During the first year, 69% of patients were readmitted to hospital. Myeloperoxidase-antineutrophil cytoplasmic antibody positivity and lower creatinine levels decreased the odds of readmission. The most common cause of death was infection, and this was associated with cumulative oral prednisolone dose. Conclusion. Immunosuppressive treatment with CYC or RTX in elderly patients with MPA and GPA was associated with development of less permanent organ damage and was not associated with hospitalization. However, higher doses of corticosteroids during the first 3 months was associated with treatment-related damage and fatal infections.
