Vasculitis is a clinically diverse group of diseases with histopathological signs of blood vessel inflammation, which contributes to vascular damage and ischemic damage to the affected tissues. Vasculitic neuropathy is a common complication of the primary systemic vasculitides, such as polyartertis nodosa and antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis, systemic diseases of the connective tissue - systemic lupus erythematosus and Sjogren syndrome, vasculitis associated with infection, most often viral hepatitis C and B and non - systemic vasculitis neuropathy. Vessels of medium and small caliber are involved in the pathological process in these diseases. With all vasculitis, except for those caused by the direct effect of the infectious trigger on the blood vessel walls, the main pathogenetic mechanism is an autoimmune process with the development of vasa nervorum vasculitis - small arteries and vessels that supply peripheral nerves, and the outcome - nerve ischemia. The classic clinical presentation is an acute or subacute painful multifocal neuropathy that has a predilection for the lower extremities, affects two or more named nerves, and progresses in a step wise manner. However, vasculitic neuropathy can manifest in a variety of ways, including asymmetric polyneuropathies and distal symmetric sensory neuropathies, and it also can be slowly progressive, particularly in cases of nonsystemic vasculitic neuropathy (NSVN), a form of vasculitis that clinically remains restricted to peripheral nerves. Nerve biopsy can help establish the diagnosis of a systemic vasculitis, particularly when other organ involvement is not clinically apparent, and is required for diagnosis of NSVN. Neuropathy due to systemic vasculitis should be treated in accordance with the recommendations for the treatment of the underlying disease. In NSVH, the main medicine of choice are glucocrticoids, and in severe/progressive cases, pulse therapy with cyclophosphamide.

ObjectiveReported prevalence of vasculitic neuropathy (VN) in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is highly variable, and associations with other organ manifestations have not been studied systematically while accounting for diagnostic certainty of VN.MethodsData of all patients with AAV within the Diagnostic and Classification criteria for primary systemic VASculitis study were analyzed cross-sectionally. VN was categorized as definite (histology proven), probable (multiple mononeuropathy or nerve biopsy consistent with vasculitis), or possible (all others). Associations with other organ manifestations were compared in patients with and without VN.ResultsNine hundred fifty-five patients (mean age 57 years, range 18–91 years, 51% female) were identified. Of these, 572 had granulomatosis with polyangiitis (GPA), 218 microscopic polyangiitis (MPA), and 165 eosinophilic granulomatosis with polyangiitis (EGPA). The prevalence of VN was 65% in EGPA, 23% in MPA, and 19% in GPA. Nerve biopsy was performed in 32/269 (12%) patients, demonstrating definite vasculitis in 17/32 (53%) of patients. VN was associated with myeloperoxidase-ANCA positivity (p = 0.004) and skin (p < 0.001), musculoskeletal, (p < 0.001) and cardiovascular (p = 0.005) involvement. Patients with VN were less likely to have renal (p < 0.001), eye (p < 0.001), and gastrointestinal (p = 0.023) involvement.ConclusionsOur study provides comprehensive insights into the prevalence and organ associations of VN in a large, systematically collected AAV cohort. VN is most commonly associated with skin, musculoskeletal, and cardiovascular manifestations. In routine clinical practice, diagnosis of VN is infrequently confirmed by the gold standard of nerve biopsy but rather supported by the clinical setting of active systemic AAV.

Systemic Process

Abstract Peripheral neuropathy is a common feature of systemic vasculitis and can also occur when vessel wall inflammation is confined to the vasa nervorum, as a tissue-specific condition—non-systemic vasculitic neuropathy (NSVN). Typically, the clinical picture in both systemic and non-systemic cases is of a lower limb predominant, distal, asymmetric or multifocal neuropathy, which is painful and subacute in onset. For NSVN, nerve biopsy is required to make the diagnosis, and nerve biopsy also has a role when vasculitic neuropathy is suspected and a systemic process has not yet declared itself. Early recognition of the disorder is important, because it is treatable, and without treatment potentially disabling, or even lethal if part of an undiagnosed systemic process. Treatment is generally with combination therapy (glucocorticoid plus other immunosuppressant), after which motor and sensory recovery are likely to occur, albeit slowly, but the patient may be left with chronic neuropathic pain.

AbstractVasculitic neuropathies are disorders that result from inflammation in the peripheral nerves' vascular supply, resulting in ischemic injury. These disorders may be a result of systemic inflammation or may be confined to the peripheral nervous system. Causative etiologies include primary systemic vasculitis, vasculitis secondary to other conditions such as primary connective tissue disorders, infectious, paraneoplastic, and drug-induced conditions, and nonsystemic vasculitic neuropathy. Early recognition and treatment of these conditions is imperative to prevent substantial morbidity and mortality. The goal of this review is to provide an organization of the vasculitic neuropathies and an overview of principles of diagnosis and treatment for the clinical neurologist.

Chronological Sequence

The analysis of the mechanisms of the formation of a rare clinical combination of pulmonary embolism (PE) and diffuse alveolar hemorrhage (DAH), which are complications of systemic vasculitis associated with antibodies to the cytoplasm of neutrophils (primarily granulomatosis with polyangiitis), systemic lupus erythematosus and secondary antiphlogistic syndrome primary antiphospholipid syndrome and Goodpastures syndrome. Taking into account the chronological sequence of the occurrence of PE and DAH, 3 variants of the onset of these potentially fatal additions to the underlying disease were considered: the anticipatory DAH development of PE, delayed from DAH PE and joint (within 24 hours) formation of PE and DAH. A review of single descriptions of such a combination of complications of granulomatosis with polyangiitis is carried out, criteria are indicated, a working classification of severity is given and, taking this into account, a modern program of therapy for DAH as an independent event and in combination with PE.

Objective:To investigate the mechanisms of vasculitis in nonsystemic vasculitic neuropathy (NSVN) and microscopic polyangiitis (MPA), focusing on complement- and antineutrophil cytoplasmic antibody (ANCA)-associated pathogenesis.Methods:Sural nerve biopsy specimens taken from twenty-four patients with NSVN and 37 with MPA-associated neuropathy (MPAN) were examined. Twenty-two patients in the MPAN group tested positive for ANCA.Results:Immunostaining for complement component C3d deposition showed more frequent positive staining of epineurial small vessels in NSVN than in MPAN (p = 0.002). The percentages of C3d-positive blood vessels were higher in the NSVN group than those in the ANCA-positive MPAN and ANCA-negative MPAN groups (p = 0.002 and p = 0.009, respectively). Attachment of neutrophils to the endothelial cells of epineurial small vessels was frequently observed in the MPAN groups, irrespective of the presence or absence of ANCA, but was scarce in the NSVN group. Immunohistochemistry using antimyeloperoxidase (MPO) antibodies revealed that the number of MPO-positive cells attached to the endothelial cells of epineurial vessels was lower in the NSVN group than that in the ANCA-positive MPAN and ANCA-negative MPAN groups (p < 0.001 and p = 0.011, respectively).Conclusions:NSVN and MPA have distinct mechanisms of vasculitis. In MPA, the attachment of neutrophils to vascular endothelial cells seems to be an initial lesion of vasculitis, regardless of the presence or absence of ANCA. Complement participated in the pathogenesis of vasculitis in NSVN.

Targeted muscle reinnervation (TMR) has been shown to improve phantom and neuropathic pain in both the acute and chronic amputee population. Through rerouting of major peripheral nerves into a newly denervated muscle, TMR harnesses the plasticity of the brain, helping to revert the sensory cortex back toward the preinsult state, effectively reducing pain. We highlight a unique case of an above-elbow amputee for sarcoma who was initially treated with successful transhumeral TMR. Following inadvertent nerve biopsy of a TMR coaptation site, his pain returned, and he was unable to don his prosthetic. Revision of his TMR to a more proximal level was performed, providing improved pain and function of the amputated arm. This is the first report to highlight the concept of secondary neuroplasticity and successful proximal TMR revision in the setting of multiple insults to the same extremity.

Eosinophilic Granulomatosis

A 66-year-old woman with a history of bronchial asthma had shortness of breath and fatigue upon mild exercise. She was diagnosed as congestive heart failure. A blood test showed eosinophilia without the presence of anti-neutrophil cytoplasmic antibody (ANCA), and a myocardial biopsy specimen revealed eosinophilic infiltration in the myocardium. Eosinophilia was improved when she was administered short-term methylprednisolone. After that, she had numbness and pain in her lower limbs with re-elevation of eosinophils. She had dysesthesia and hypalgesia in the distal part of the limbs. Sural nerve biopsy revealed axonal degeneration and thickness of the arterial wall, indicating a diagnosis of eosinophilic granulomatosis with polyangiitis (EGPA). Two courses of steroid pulse therapy were performed, resulting in marked improvement of her sensory symptoms. ANCA-negative EGPA might be associated with myocarditis and peripheral neuropathy. A sufficient immunotherapy should have been considered to prevent rapid progression.

Background: Warm autoimmune haemolytic anaemia (wAIHA) is a haemolytic disorder, most commonly seen among adults and is classified as either primary or secondary to an underlying disease. We describe the age and sex distribution and the proportion of secondary wAIHA. Method: We retrieved 2635 published articles, screened abstracts and titles, and identified 27 articles eligible for full-text review. From these studies, we extracted data regarding number of patients, sex distribution, age at diagnosis, number of patients with secondary wAIHA, and whether the patients were diagnosed through local or referral centres. All data were weighted according to the number of included patients in each study. Results: 27 studies including a total of 4311 patients with wAIHA, of which 66% were females, were included. The median age at diagnosis was 68.7 years, however, wAIHA affected all ages. The mean proportion of secondary wAIHA was 49%, most frequently secondary to systemic lupus erythematosus. The proportions of secondary wAIHA reported from primary vs. referral centres were 35% vs. 59%, respectively. Conclusion: This review consolidates previously reported gender distribution. The higher proportion of secondary wAIHA in referral centres suggests that the most severely affected patients are disproportionally more frequent in such facilities.

The authors report a case of a 19-year-old woman admitted for the investigation of fever and hemolytic anemia for the previous 2 months. As an inpatient, she had convulsions and sudden loss of consciousness, developing hemoptysis, hypoxia, and respiratory insufficiency. Examination showed pericardial effusions on the echocardiogram and bilateral alveolar condensations on the thoracic radiograph. A hypothetical diagnosis of systemic lupus erythematosus was made, and measurement of the antinuclear factor was requested along with daily pulse therapy methylprednisolone, in spite of which the outcome was fatal. Afterwards, the result of the antinuclear factor test was positive, with a titer of 1:5120, showing a fine punctiform pattern, fulfilling the criteria for systemic lupus erythematosus according to the American College of Rheumatology. Secondary pulmonary hemorrhage in this connective tissue disease is an uncommon but serious complication that involves a high level of mortality in spite of intensive treatment, as is also reported in the literature.
