Influence of low socioeconomic status on mortality in granulomatosis with polyangiitis.

Objectives: To evaluate the influence of low socioeconomic status (SES) on mortality among patients with granulomatosis with polyangiitis (GPA).Methods: Using nationwide registers, we established a cohort of 827 patients diagnosed with GPA in the public hospital system of Denmark. For each patient, information regarding educational level, civil status, employment status, and comorbidities at time of GPA diagnosis was collected. We used Cox regression analyses to calculate hazard ratios (HRs) adjusted for age, gender, calendar period of GPA diagnosis, and Charlson Comorbidity Index score for preceding illnesses as a measure of relative risk of death. We assessed the risk of death associated with three measures of low SES: basic schooling only, civil status as single, and being unemployed or recipient of disability pension.Results: The median age of patients at GPA diagnosis was 61 (interquartile range 51-69) years, and 508 were 18-64 years old. During a total of 4337 person-years, 237 patients died. Among patients aged 18-64 years at GPA diagnosis, all three measures of low SES were identified as risk factors for death [basic schooling only: HR = 2.04, 95% confidence interval (CI) 1.30-3.19; civil status as single: HR = 1.95, 95% CI 1.24-3.05; being unemployed or recipient of disability pension: HR = 2.96, 95% CI 1.72-5.08]. The association between low SES and mortality was less pronounced among patients aged ≥ 65 years.Conclusions: Our observations indicate that low SES is associated with increased mortality in GPA, especially among patients of working age.

Inpatient epidemiology and economic burden of granulomatosis with polyangiitis: a 10-year study of the national inpatient sample.

OBJECTIVE: To characterize inpatient epidemiology and economic burden of granulomatosis with polyangiitis (GPA). METHODS: Patients with GPA were identified from the Nationwide Inpatient Sample (NIS), the largest inpatient database in the USA consisting of over 4000 non-federal acute care hospitals, using the ICD-9 CM code. A cohort of comparators without GPA was also constructed from the same database. Data on demographics, procedures, length of stay, mortality, morbidity and total hospitalization charges were extracted. All analysed data were extracted from the database for the years 2005-2014. RESULTS: The inpatient prevalence of GPA was 32.6 cases per 100 000 admissions. GPA itself (38.3%), pneumonia (13.7%) and sepsis (8.4%) were the most common reasons for admission. After adjusting for potential confounders, the all-cause mortality adjusted odds ratio (aOR) of patients with GPA was significantly higher than that of patients without GPA (aOR 1.20; 95% CI: 1.41, 1.61). This was also true for several morbidities, including acute kidney injury, multi-organ failure, shock and need for intensive care unit admission. Hospitalizations of patients with GPA were associated with higher cost as demonstrated by an adjusted additional mean of $5125 (95% CI: $4719, $5531) for total hospital cost and an adjusted additional mean of $16 841 (95% CI: $15 280, $18 403) for total hospitalization charges when compared with patients without GPA. CONCLUSION: Inpatient prevalence of GPA was higher than what would be expected from prevalence in the general population. Hospitalizations of patients with GPA were associated with higher morbidity, mortality and cost.

Presentation and initial assessment of ENT problems in patients with granulomatosis with polyangiitis (Wegener's).

BACKGROUND: Granulomatosis with polyangiitis (formerly known as Wegener's granulomatosis) is a primary systemic vasculitis that affects medium to small sized vessels throughout the body. It often presents with symptoms and signs involving the ear, nose, and head and neck area. OBJECTIVE: To highlight salient features of ENT-related issues in granulomatosis with polyangiitis, and raise awareness of the condition. METHODS: A case report of a patient with limited disease and an insidious onset is presented, along with a review of the current literature. In addition, basic initial management is described. RESULTS: Eighty-six publications were used to describe salient features of ENT-related issues in granulomatosis with polyangiitis. CONCLUSION: The time to diagnosis has not reduced significantly in the last 10 years in the UK. A high index of suspicion is required for an earlier diagnosis of granulomatosis with polyangiitis.

Effect of Wegener's granulomatosis on work disability, need for medical care, and quality of life in patients younger than 40 years at diagnosis.

OBJECTIVES: To evaluate the effects of Wegener's granulomatosis (WG) on employment status, work disability, and need for medical care of 60 consecutive WG patients aged < or = 40 years at diagnosis. METHODS: Sixty WG patients (26 male, 34 female) with a median age of 36 years (range 17-48 years) and a median duration of disease of 39 months (range 0-228 months) completed self-administered questionnaires on hospitalization, medical care, and employment status plus the Medical Outcomes Study-Short Form-36 (SF-36) estimating their health-related quality of life. RESULTS: Thirty-two of the 60 patients reported full- or part-time employment more than 3 years after diagnosis. Only 14 of the 51 patients employed at diagnosis (27%) were currently receiving a permanent work disability pension due to WG. Two additional patients had lost work because of WG. Women who were employed at diagnosis had a nearly 3-fold higher risk of losing their jobs compared with men (P = 0.0006). There were no differences with regard to age at diagnosis, disease duration, disease severity, or education level between employed and unemployed patients. Employed patients had missed a median of 14 workdays (range 0-18 days) due to WG within the past 12 months. More than half of all patients (33 of 60) had been hospitalized during the previous 12 months because of WG. Ninety-three percent of all patients had visited their physician once or more per month, more than half of them at least once per week, regardless of employment status, severity of disease, or type of current medication. Unemployed WG patients experienced significant reductions in social and physical function and in their perceived degree of general health as assessed by the SF-36. CONCLUSIONS: Twenty-seven percent of WG patients younger than age 40 who were employed at diagnosis received permanent work disability within a disease duration of 39 months. Unemployment is followed by a considerable reduction in disease-related quality of life compared with employed patients, independent of severity and extent of disease. Furthermore, because patients were followed closely by an interdisciplinary team, a high rate of hospitalization and frequent visits to physicians resulted.

Wegener's granulomatosis: disease course, assessment of activity and extent and treatment.

Wegener's granulomatosis (WG) belongs to the group of necrotizing primary systemic vasculitides of unknown etiology, that are associated with anti-neutrophil cytoplasmic antibodies. The pathological hallmark of WG is the coexistence of vasculitis and granuloma. Due to more sensitive diagnostic instruments, especially ANCA testing, the incidence of diagnosis of WG has risen in the past ten years. Although the precise pathophysiology is not understood yet, there is ample evidence that ANCA, which can lead to cytotoxic reactions in the vascular texture, play a major role, possibly promoted by a dysbalance in the anti-idiotypic network. The clinical disease course is typically two-phasic, beginning with a granulomatous inflammation of the upper respiratory tract, that usually is followed by a generalized vasculitic phase, that can range from mild organ dysfuntion to life threatening multi-organ failure. Consequently, diagnostic procedures, patients' assessment and therapeutic regimens need to be individualized, adapted to stage and activity of the disease as well as standardized.
