RESUMEN
Infections in patients with systemic vasculitis represent one of the main causes of mortality. Corticosteroid use, immunosuppressive therapy, age, associated organic involvement and dialysis dependence are risk factors of infection. OBJECTIVES: To determine the prevalence of severe infection and associated factors in patients diagnosed with ANCA-associated vasculitis (AAV) and Polyarteritis Nodosa (PAN). METHODS: retrospective study was conduced in a single rheumatology center (2000-2018). We included patients diagnosed with AAV (Granulomatosis with Polyangiitis (GPA), Eosinophilic Granulomatosis with Polyangiitis (EGPA) and Microscopic Polyangiitis (PAM) and Polyarteritis nodosa (PAN). Serious infectious events requiring hospitalisation or prolonged antibiotic/antiviral treatment, recurrent infection of Herpes Zoster Virus or opportunistic infections were evaluated. Sites of infection, isolated microorganisms and mortality related were analyzed. RESULTS: 105 patients were analyzed, follow-up time median 18â¯m, 58.7% were women and median age was 52 years. Types of vasculitis: 41.9% PAM, 16.2% EPGA, 40% GPA, 1.9% PAN. Constitutional, pulmonary, renal and otorhinolaryngology manifestations were the most frequent. PREVALENCE OF INFECTION: 34.2%, with a median of 3 months from diagnosis of vasculitis to the infectious event. Low respiratory tract (42.8%), sepsis (31.4%), and urinary tract (14.3%) were the most common sites of infections. Bacterial aetiology was the most prevalent (67.7%). Mortality at the first event was 14.3% and a 72.2% of patients were in the induction phase of treatment. Infectious events were significantly associated with age > 65 years (pâ¯=â¯0.030), presence of lung (pâ¯=â¯0.016) and renal involvement (pâ¯=â¯0.001), BVASv3â¯>â¯15, mortality (pâ¯=â¯0.0002). CONCLUSIONS: The prevalence of infection was 34.2%. Lower airway infections, septicemia and urinary tract infections were the most prevalent. Infections were associated with renal and pulmonary involvement, age older than 65 years and score BVASâ¯>â¯15. Severe infections were associated with mortality, especially in elderly patients.

INTRODUCTION: Vasculitides are a heterogeneous group of disorders producing inflammation of blood vessels (e.g. arteries or veins). All major vasculitides potentially have ophthalmological symptoms and signs including visual loss. Co-morbidity, multimorbidity, polypharmacy, and geriatric syndromes all play important roles in patient outcomes for these rheumatic conditions in the elderly. This monograph reviews the NCBI PubMed database (Feb 2023) literature on the neuro-ophthalmic and geriatric considerations in vasculitis. AREAS COVERED: Cogan Syndrome, Granulomatosis with Polyangiitis, Giant Cell Arteritis, Polyarteritis Nodosa, Takayasu Arteritis, Vasculitis epidemiology, and neuro-ophthalmological symptoms. EXPERT OPINION: Geriatric patient care for vasculitis with neuro-ophthalmological manifestations can be complicated by the interplay of multiple co-morbidities, polypharmacy, and specific geriatric syndromes. The valuation and treatment of vasculitis and the complications associated with the disease can negatively impact patient care. Advances in noninvasive imaging and updates in diagnostic criteria have enabled increased identification of patients at earlier stages with less severe disease burden. Novel therapeutic agents can be glucocorticoid sparing and might reduce the adverse effects of chronic steroid use. Holistic care models like the 5 M geriatric care model (mind, mobility, medications, multicomplexity, and matters most) allow patients' needs to be in the forefront with biopsychosocial aspects of a patient being addressed.

BACKGROUND: The landscape of polyarteritis nodosa (PAN) has substantially changed during the last decades. Recent data regarding causes, characteristics, and prognosis of systemic PAN in the modern era are lacking. METHODS: This retrospective study included patients with systemic PAN referred to the French Vasculitis Study Group between 2005 and 2019. Characteristics, associated conditions and outcomes were collected, and predictors of relapse and death were analyzed. RESULTS: 196 patients were included. Main clinical symptoms were constitutional (84%), neurological (59%), skin (58%) and musculoskeletal (58%) manifestations. Secondary PAN accounted for 55 (28%) patients, including myelodysplastic syndrome (9%), solid cancer (7%), lymphoma (4%) and autoinflammatory diseases (4%). No patient had active HBV infection. All treated patients (98.5%) received glucocorticoids (GCs), alone (41%) or in combination with immunosuppressants (59%), with remission achieved in 90%. Relapses were independently associated with age >65 years (HR 1.85; 95% CI1.12-3.08), gastrointestinal involvement (1.95; 95% CI1.09-3.52) and skin necrotic lesions (HR 1.95; 95%CI 1.24-3.05). One-, 5- and 10-year overall survival rates were 93%, 87% and 81%, respectively. In multivariate analyses, age >65 years (HR 2.80; 95%CI 1.23-6.37), necrotic purpura (HR 4.16; 95%CI 1.62-10.70), acute kidney injury (HR 4.89; 95% 1.71-13.99) and secondary PAN (HR 2.98; 95%CI 1.29-6.85) were independently associated with mortality. CONCLUSION: Landscape of PAN has changed during the last decades, with the disappearance of HBV-PAN and the emergence of secondary PAN. Relapse rate remains high, especially in aged patients with gastrointestinal and cutaneous necrosis, as well as mortality.

OBJECTIVES: This study aimed to clarify the epidemiological and clinical features and treatment of patients with polyarteritis nodosa (PAN) in Japan. METHODS: We used the database of the Ministry of Health, Labour and Welfare (MHLW) of Japan in 2013 and 2014. We analysed 121 patients who were antineutrophil cytoplasmic antibodies negative among the patients certified as PAN according to the MHLW diagnostic criteria. RESULTS: The analysis included 60 males and 61 females, with a mean age of 52.9 ± 21.0 years. As a general manifestation, fever was observed in 53.7%. Regarding organ involvement, skin manifestations (82.6%), joint and muscle manifestations (75.2%), and neuropsychiatric manifestations (50.4%) were common. Male patients had a higher proportion of mononeuritis multiplex involving motor neuropathy than female patients. Elderly patients had a higher proportion of general and respiratory manifestations. Glucocorticoids were used for treatment in all patients, and 19.0% underwent methylprednisolone pulse. Concomitant immunosuppressants were used in 25.6%, one-third of whom received cyclophosphamide. Methylprednisolone pulse and cyclophosphamide were mostly used in patients with life-threatening organ involvement. CONCLUSIONS: PAN developed in middle-aged people and led to numerous clinical manifestations. The common manifestations varied with age, and treatment was determined based on the type of organ involvement and disease severity.

BACKGROUND: Diagnosis of childhood polyarteritis nodosa (PAN) has become challenging after the definition of deficiency of adenosine deaminase 2 (DADA2). We aimed to define the differential features of pediatric PAN and DADA2 patients in our center and in the literature. METHODS: The charts of pediatric PAN and DADA2 patients followed at the Pediatric Rheumatology Unit of Hacettepe University between 2010-2020 were analyzed. A systematic literature review was conducted for articles regarding pediatric PAN or DADA2. RESULTS: Thirty-four pediatric PAN and 18 pediatric DADA2 patients were included. The age at onset was younger, parental consanguinity, livedo reticularis, neurologic involvement (especially strokes), lymphopenia, and hypogammaglobulinemia were more frequent, while thrombocytosis and panniculitis were less frequent in DADA2 patients. The primary treatment was anti-tumor necrosis factor (anti-TNF) in DADA2. For induction treatment, all systemic PAN patients received corticosteroids, and cyclophosphamide (n=11) or mycophenolate mofetil (MMF) (n = 3). Cyclophosphamide was replaced with MMF in nine once remission was confirmed with PVAS. In the literature, 28 articles describing 613 pediatric PAN patients and 26 articles describing 207 pediatric DADA2 patients were identified. Neurologic, gastrointestinal, and cardiac involvements were more frequent in DADA2, while constitutional symptoms and testis involvement were more common in PAN. CONCLUSION: In a child with PAN-like phenotype, DADA2 should be considered in the presence of young age at disease onset, parental consanguinity, strokes, lymphopenia, and lack of thrombocytosis during active disease. Anti-TNF treatment is indicated for vasculitic DADA2. Cyclophosphamide could be switched to MMF when remission is confirmed with PVAS in severe PAN.

METHODS: We conducted a medical records review study (1975-2018) that included patients with childhood- and adult-onset PAN. Demographics, organ involvement, phenotype, treatment, and outcomes were assessed and compared against previously published cohorts. RESULTS: Thirty-one patients were included, 20 (64.5%) female, with a median age at diagnosis of 28 years (interquartile range [IQR], 16-42). Seven (23%) were classified as cutaneous; 23 (74%), systemic; and 1 (3%), progressive systemic phenotype. Eleven patients (35%) had childhood-onset PAN. Most common manifestations were musculoskeletal (71%), cutaneous (68%), constitutional (61%), peripheral neuropathy (39%), and gastrointestinal (29%). The median Birmingham Vasculitis Activity Score and Five-Factor Score at diagnosis were 9 (IQR, 4-13) and 1 (IQR, 0-1), respectively. Most patients were treated with glucocorticoids (94%). Twenty-four (80%) achieved complete and 6 (20%) partial remission at a median follow-up time of 30 months (8-192 months). The median Vasculitis Damage Index at last follow-up was 1 (IQR, 0-1). Nineteen (66%) experienced relapses. Patients with childhood-onset PAN more frequently had central nervous system and gastrointestinal involvement (36% vs 5%, p = 0.04 and 64% vs 10%, p = 0.003, respectively), microaneurysms (100% vs 38%, p = 0.02), and lower levels of C-reactive protein (0.3 vs 15.4 mg/dL, p = 0.03), compared with adult-onset PAN patients. CONCLUSIONS: Our cohort of PAN patients showed predominantly a systemic phenotype. Outcomes were generally good, with most patients achieving complete remission. Childhood-onset differed from adult-onset PAN in terms of clinical and serological characteristics, whereas clinical manifestations and outcomes may be different than the ones reported in other cohorts.

Childhood-onset polyarteritis nodosa (PAN) is a rare and systemic necrotising vasculitis in children affecting small- to medium-sized arteries. To date, there have been only a few reports because of its rarity. Thus, we aimed to investigate the clinical manifestations, laboratory findings, treatment, and long-term outcomes in patients with childhood-onset PAN and to evaluate the usefulness of the paediatric vasculitis activity score (PVAS). We retrospectively analysed the data of nine patients with childhood-onset PAN from March 2003 to February 2020. The median ages at symptom onset, diagnosis, and follow-up duration were 7.6 (3-17.5), 7.7 (3.5-17.6), and 7.0 (1.6-16.3) years, respectively. All patients had constitutional symptoms and skin manifestations, while five exhibited Raynaud's phenomenon. Organ involvement was observed in one patient. The median PVAS at diagnosis was 7 (range: 2-32). Prednisolone was initially used for induction in all patients, and other drugs were added in cases refractory to prednisolone. All patients survived, but three patients with high PVAS at diagnosis experienced irreversible sequelae, including intracranial haemorrhage and digital amputation. In conclusion, early diagnosis and treatment may minimise sequelae in patients with childhood-onset PAN. This study suggests that high PVAS score at diagnosis may be associated with poor prognosis.

Cardiac vasculitis is recognized as a heterogeneous disease process with a wide spectrum of manifestations including pericarditis, myocarditis, valvular heart disease and less frequently, coronary artery vasculitis (CAV). CAV encompasses an emerging field of diseases which differ from conventional atherosclerotic disease and have a proclivity for the younger population groups. CAV portends multiple complications including the development of coronary artery aneurysms, coronary stenotic lesions, and thrombosis, all which may result in acute coronary syndromes. There are several aetiologies for CAV; with Kawasaki's disease, Takayasu's arteritis, Polyarteritis Nodosa, and Giant-Cell Arteritis more frequently described clinically, and in literature. There is a growing role for multi-modality imaging in assisting the diagnostic process; including transthoracic echocardiography, cardiac magnetic resonance imaging, computed tomography coronary angiography, fluorodeoxyglucose-positron emission tomography and conventional coronary angiogram with intravascular ultrasound. Whilst the treatment paradigms fundamentally vary between different aetiologies, there are overlaps with pharmacological regimes in immunosuppressive agents and anti-platelet therapies. Interventional and surgical management are is a consideration in select populations groups, within a multi-disciplinary context. Further large-scale studies are required to better appropriately outline management protocols in this niche population.

BACKGROUND: Coronary artery involvement is a severe but uncommon manifestation of polyarteritis nodosa (PAN), so clinicians have little knowledge of it. Our aim was to investigate the clinical characteristics, risk factors and outcomes of patients with PAN complicated with coronary artery lesions. METHODS: Data from 145 patients with PAN who were admitted to Peking Union Medical College Hospital from January 2000 to September 2019 were retrospectively collected. RESULTS: Nineteen patients (13.1%) had coronary artery lesions due to PAN. The age at the onset of PAN was 32.3 ± 11.8 years. There were no significant differences in common risk factors for coronary arterial atherosclerosis between the patients with coronary artery involvement and those without. Affected branches of the coronary arteries were left anterior descending branch (15 patients), right coronary artery (14 patients), and left circumflex branch (9 patients). Eleven of the 19 patients exhibited multivessel lesions. Multivariate logistic regression analysis showed that celiac artery involvement (odds ratio [OR] 3.722, 95% confidence interval [CI] 1.115-12.427; P = 0.033) and new-onset hypertension (OR 6.668, 95% CI 1.936-22.961; P = 0.003) were risk factors for coronary artery involvement in patients with PAN. Stent placement was performed for 2 patients, and in-stent restenosis occurred in 1 of those patients a year later. CONCLUSIONS: PAN with coronary artery involvement exhibits more combined involvement of arteries of other organs and more severe diseases. PAN should be considered when treating young adults with an unknown origin of coronary artery lesions. In addition to systemic immunosuppressive treatment, other measures including antiplatelet and anticoagulation therapy should be initiated; however, determining the optimal time to perform procedures such as intervention or surgery is still challenging.

PURPOSE OF THE REVIEW: Rheumatic diseases usually have very diverse and complex pathophysiology resulting in different clinical phenotypes. Some certain phenotypes cluster together with a common presentation, course, and outcome. Our primary aim is to review the known disease clusters in certain rheumatological conditions. RECENT FINDINGS: Cluster analysis has been reported in several rheumatic diseases, Behcet disease being the most common. Five individual clusters together with some clinical associations have been reported in Behcet patients. Certain antibody-phenotype associations and damage clusters have been reported in systemic lupus erythematosus (SLE) patients as well. Although there is no proper cluster analysis, two distinct phenotypes are evident in deficiency of ADA2 (DADA2): those with a polyarteritis nodosa-like vasculopathy and hematological involvement with pure red cell aplasia or bone marrow failure. The variants are claimed to be different regions of this gene for these 2 phenotypes. Lastly, there is a recent paper grouping ANCA-associated vasculitis according to disease phenotype and antibody associations. There are distinct clusters in certain rheumatic diseases which might help us to predict comorbidities, disease course, and treatment response.

OBJECTIVES: To characterize inpatient burden, expenditures and association with comorbidities of polyarteritis nodosa (PAN). METHODS: Patients with PAN were identified from the Nationwide Inpatient Sample (NIS) database for the year 2014 using ICD-9 diagnostic codes. The primary outcome was determining the inpatient prevalence of PAN in hospitalized patients in the US. Secondary outcomes included determining inpatient mortality, morbidity, comorbidities, hospital length of stay (LOS) and total hospital costs and charges. A cohort of patients without PAN was also identified from the same database to serve as comparators for analysis of comorbidities. Multivariate regression analysis was used to adjust for age, gender, ethnicity, comorbidities and hospital characteristics. RESULTS: A total of 4,110 patients with PAN were included in the study. The mean age was 59.5 years and 61% were female. The inpatient prevalence of PAN was 11.6 cases per 100,000 discharges. Patients with PAN displayed increased adjusted odds of mortality (OR:1.35, pâ¯=â¯0.13), shock (OR:1.75, p<0.01), ICU admission (OR:1.88, p<0.01) and multiorgan failure (OR:3.12, p<0.01) compared to patients without PAN. Patients with PAN also displayed significantly higher hospital costs (additional adjusted mean [aAM]: $9,693, p<0.01), hospitalization charges (aAM: $34,273, p<0.01) and LOS (aAM: 4.1 days, p<0.01) compared to patients without PAN. Analysis of comorbidities found a significant association between PAN and venous thromboembolism, renal injury and sepsis. The main limitation of this study was reliance on accuracy of diagnostic coding. The high inpatient prevalence of PAN might have been inflated and we cannot be certain that the higher risk of comorbidities and expenditures were entirely attributable to PAN as some patients in this cohort may have other vasculitides. CONCLUSIONS: The inpatient prevalence of PAN is higher than what would be expected from the overall general prevalence. Hospitalizations of patients with PAN are associated with significantly higher rates of morbidity and expenditures.

OBJECTIVES: FMF is the most common periodic fever syndrome, characterized by recurrent episodes of fever and serosal inflammation accompanied with high acute phase reactants. The analysis of possible comorbidities is important to understand the impact of these conditions on clinical care and whether they share a common aetiological pathway. In this study, we aimed to evaluate the comorbidities associated with FMF patients in a large genetically diagnosed cohort. METHODS: We retrospectively evaluated the medical and genetic records of FMF patients who were followed up by rheumatologists in Hacettepe University for 15 years. The FMF patients who had homozygous or compound heterozygous mutations were included in the study. Comorbidities associated with FMF were divided into three groups: (i) comorbidities directly related to FMF, (ii) comorbidities due to increased innate inflammation, and (iii) comorbidities that were regarded as being incidental. RESULTS: A total of 2000 patients with a diagnosis of FMF were enrolled in the study. Among them 636 were children (31.8%) and M694V was the most common mutation in patients with associated inflammatory conditions. The frequency of AS, Iga Vasculitis (Henoch-Schönlein purpura), juvenile idiopathic arthritis, polyarteritis nodosa, multiple sclerosis and Behçet's disease were increased in patients with FMF when compared with those in the literature. CONCLUSION: This study represents the largest genetically confirmed cohort and compares the frequencies with existing national and international figures for each disease. The increased innate immune system inflammation seen in FMF may be considered as a susceptibility factor since it predisposes to certain inflammatory conditions.

OBJECTIVES: Polyarteritis nodosa is a necrotising vasculitis of predominantly medium size vessels. The present study aimed to summarise the characteristics of PAN patients, and also analyse the trend of decreasing PAN frequency in the last 25 years. METHODS: PAN patients followed up between 1990 and 2015 were included. The demographics, clinical findings and outcomes were retrospectively evaluated. RESULTS: One hundred thirty-three patients, including 66 children, were enrolled in the study. Among 133 patients, 86 (64.7%) had fever, 108 (81.2%) had skin involvement, 54 (40.6%) had renal involvement, 43 (32.3%) had neurological involvement, 32 (24.1%) had gastrointestinal involvement, 10 (7.5%) had cardiac involvement, 6 (4.5%) had pulmonary involvement. The median (minimum-maximum) leukocyte count, erythrocyte sedimentation rate and C-reactive protein levels at the time of diagnosis were 10400 (6100-32000)/mm3, 58 (2-132) mm/h and 5.22 (0-46) mg/dL, respectively. All patients were ANCA negative. Hepatitis serology was analysed in 121 patients and found positive in 13 of them. MEFV mutations were screened among 65 patients, 24 of them had mutations in at least one allele. Biopsy was performed in 109 patients and angiography was performed in 92 patients. The number of PAN patients declined significantly after 2010. 9 patients were re-categorised as DADA2 after 2014 and no patient were diagnosed with FMF+PAN after 2008. CONCLUSIONS: Our results suggest a decrease in PAN in our country which may be due to improved healthcare and dissecting mimicking diseases. Further prospective studies with prolonged follow-up could help us to better understand the disease characteristics.

OBJECTIVE: To investigate differences between childhood (cPAN)- and adult-onset polyarteritis nodosa (aPAN) patients. METHODS: cPAN patients' clinical findings at onset and outcomes were compared to those of aPAN patients from the French Vasculitis Study Group registry matched for year of enrollment and initial systemic versus cutaneous disease. Their information on medications, disease activity and damage were collected. Kaplan-Meier relapse-free survival curves and the log-rank test were used to analyze cPAN versus aPAN differences for predefined outcomes. RESULTS: Twenty-one children with systemic and 13 with cutaneous PAN were compared with 84 systemic- and 27 cutaneous-matched aPAN patients. Median follow-up exceeded 5â¯years for both groups. At study entry, mononeuritis multiplex was less frequent in systemic cPAN than systemic aPAN (Pâ¯=â¯0.04), and purpura and myalgias were less frequent in cutaneous cPAN than cutaneous aPAN (Pâ¯<â¯0.03). During follow-up, systemic cPAN relapsed more often than matched systemic aPAN (Pâ¯<â¯0.0001), while relapse rates were similar for cutaneous disease (Pâ¯>â¯0.05). Mostly minor relapses, predominantly involving the skin, occurred in all 4 groups. At last visit, damage accrual was comparable for cPAN and aPAN patients, but fewer systemic cPAN patients were treatment-free (15% versus 42%; Pâ¯=â¯0.03). Two (6%) cPAN and 8 (7%) aPAN patients died. CONCLUSION: Systemic PAN is equally severe in children and adults and carries a higher risk of relapse. The main cutaneous PAN features seem not to be influenced by age at disease onset.

OBJECTIVE: The aim of the study was to describe the evolution of mortality and cause-specific mortality over time in patients with systemic necrotizing vasculitides (SNV), including polyarteritis nodosa (PAN), granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA). METHODS: Patients with SNV from the French Vasculitis Study Group registry were divided into 5 groups according to the date of diagnosis: <1980, 1980-1989, 1990-1999, 2000-2010, and ≥â¯2010. The causes of death were classified as vasculitis, infection, cardiovascular, malignancy, miscellaneous, or unknown. RESULTS: Among the 2217 patients included (PAN 16.1%, GPA 41.7%, EGPA 22.6%, MPA 19.6%), overall incidence of death was 2.26 per 100 person-years. The overall survival improved during each period considered. The 5-year survival rate increased from 72.2% (95% confidence interval [CI] 59.7-87.2) for patients diagnosed before 1980 to 94.5% (95% CI 90.4-98.8) after 2010 (pâ¯<â¯0.001). Periods of diagnosis, age, and male gender were independently associated with a poor survival with a non-significant difference between vasculitis. The incidence of mortality between the 1980s and after 2010 significantly decreased for vasculitis-related (pâ¯=â¯0.03) and cardiovascular-related deaths (pâ¯=â¯0.04). Incidence of death by infection remained stable between the 1980s and the 2000s but no death by infection occurred after 2010. The incidence of death by malignancy remained stable over time. CONCLUSION: Overall survival of SNV patients has improved since the 1980s with the decrease of vasculitis- and cardiovascular-related deaths, but cancer-related mortality remained stable. These results highlight malignancy as the current target to improve the overall prognosis.

OBJECTIVES: To estimate the annual incidence rate of paediatric primary systemic vasculitis (PSV) in a defined geographical area in southern Sweden. METHODS: Potential cases of PSV [IgA vasculitis (IgAV, Henoch-Schönlein purpura), Kawasaki disease (KD), granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), eosinophilic granulomatosis with polyangiitis (EGPA), polyarteritis nodosa (PAN), and Takayasu's arteritis (TAK)] were identified in a comprehensive regional healthcare register. The study area is Skåne, the southernmost county of Sweden (population 1.29 million; 21.4% aged <18 years). Case records for children (0-17 years) assigned a diagnosis code between M300 and M319 and/or D690 were reviewed to ascertain diagnosis. Only patients diagnosed between 2004 and 2014 were included. RESULTS: In total, 556 patients with PSV were identified. The annual incidence rate per million children (95% confidence interval) was estimated to be 200 (183-217) for all PSV, 175.5 for IgAV (160-191), 20.1 for KD (14.9-25.4), 1.4 (0-2.8) for each of GPA and MPA, 0.7 (0-1.7) for PAN, and 0.4 (0-1.1) for each of EGPA and TAK. Among children aged <10 years, 99.5% of cases were either IgAV or KD, both exhibiting a seasonal pattern paralleling infections. There were no deaths, but three cases of end-stage renal disease were noted, all in MPA. CONCLUSIONS: Vasculitis is relatively common during childhood. Mild cases associated with the infection season are most common in the youngest age groups, while during adolescence a substantial proportion has more severe forms of vasculitis.

AIM: To determine mortality and its predictive factors in Japanese patients with polyarteritis nodosa (PAN). METHODS: This retrospective single-center study determined the mortality of 18 patients with PAN who were admitted to Juntendo University Hospital from 1994 to 2016. The variables at baseline, including patient demographics, clinical characteristics, and treatment, were analyzed for their association with mortality. RESULTS: The median age of onset was 57.0 years. The 1-year survival rate was 100% (16/16) and the 5-year survival rate was 80.0% (8/10). The relationship between mortality, as defined by the survival rate and each variable was evaluated by Cox univariate analysis. A higher 2009 five-factor score (FFS) was associated with increased mortality, with a hazard ratio of 2.34 (p = .04). Analysis of the secondary outcome of relapse-free survival time revealed an association with rapid progressive renal failure, Birmingham Vasculitis Activity Score (BVAS), the 1996 FFS, and the 2009 FFS, with hazard ratios of 7.28 (p = .048), 1.26 (p = .02), 2.32 (p = .03), and 1.82 (p = .04), respectively. CONCLUSION: We investigated mortality, relapse-free survival, and their predictive factors in Japanese patients with PAN. The BVAS and the 1996 FFS at diagnosis may be prognostic factors for relapse-free survival, and the 2009 FFS at diagnosis may be a prognostic factor for both mortality and relapse-free survival.

Cutaneous vasculitis, inflammatory destruction of blood vessels, can present with a wide range of clinical and pathologic findings across a number of heterogeneous conditions. Although some vasculitides are present in both children and adults, some important differences exist in clinical presentation, etiology, management, and prognosis in childhood vasculitis versus adult vasculitis. Cutaneous vasculitis is rare in children, and most childhood vasculitides, of which Henoch-Schönlein purpura is the most common, histologically are small vessel leukocytoclastic vasculitis. In children, infectious etiologies are more common than in adults. Childhood cutaneous vasculitis is most often self-limited with a good prognosis, and treatment is mainly supportive. © 2017 Elsevier Inc. All rights reserved.

OBJECTIVE: There has been a significant decrease in the number of published reports of classical polyarteritis nodosa (PAN) in the post-Chapel Hill consensus conference (CHCC) nomenclature era with only two series published from Asia. We report a case series of PAN from north India. PATIENTS AND METHODS: A retrospective study of all patients diagnosed to have PAN according to American College of Rheumatology criteria/CHCC nomenclature. The details of clinical presentation, investigation findings, treatment details and outcomes were noted from the records. These findings between the hepatitis B positive and negative groups were compared. RESULTS: Twenty-seven patients (20 male, seven female) were diagnosed as having PAN, out of which seven (25.9%) were hepatitis B surface antigen positive. Nervous system involvement was most common with 24 patients (88.9%) having mononeuritis multiplex. Weight loss was present in 20 (74%), fever in 14 (51.9%), renal involvement in 16 (59.3%), cutaneous in nine (33.3%), peripheral gangrene in eight (29.6%), gastrointestinal (GI) involvement in eight (29.6%), testicular pain in 6/20 (30%) and cardiac involvement in four (14.8%). Twenty-three (85.2%) patients recovered, three died (11.1%) and one was lost to follow-up. Median follow-up duration was 37 (interquartile range 22.00-69.75) months. The cumulative survival was 114.16 months (95% CI: 98.27-129.95). There was no significant difference in five factor score (FFS) or revised FFS between those patients who died and those who survived (P = 0.248, 0.894, respectively). Hepatitis B-related PAN had a lower FFS compared to non-hepatitis B-related PAN (P = 0.039). No other significant differences were noted between the two groups. CONCLUSION: In comparison to classic PAN in other populations, classic PAN in north India is associated with higher neurological involvement and lower GI involvement.
