Familial Association of Granulomatosis With Polyangiitis: A Case-Based Review of Literature.

ABSTRACT: Anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV) is a class of small vessel vasculitis that includes granulomatosis with polyangiitis (GPA), eosinophilic GPA (EGPA), and microscopic polyangiitis (MPA). Despite extensive research, the mechanisms behind AAV etiology remain obscure. The genetics of AAV is a complex area of investigation because of the rarity of familial cases. However, recent multi-center genome-wide association studies (GWAS) have greatly contributed to our understanding of the genetic basis of AAV. In this study, we report a rare occurrence of GPA in two Caucasian family members who presented with similar clinical symptoms and performed a comprehensive review to study the present literature available regarding the heritability of this disease.

Project description:BackgroundGranulomatosis with polyangiitis (GPA), a necrotizing granulomatous disease, very rarely involves the central nervous system (CNS), particularly the pituitary. Delayed treatment may cause permanent bilateral blindness. We report an isolated case of pituitary GPA that manifested as a progressive bilateral temporal visual field (VF) defect and was diagnosed via pituitary biopsy. Additionally, we review ocular, chiasmal and cranial nerve involvement in pituitary GPA.Case presentationA 20-year-old Chinese man was referred for repeated fever, sudden headache, diplopia with a bilateral best-corrected visual acuity (BCVA) of 10/20, ptosis in both eyes and restricted abduction on the right side. VF tests showed bitemporal hemianopsia. Laboratory tests revealed hypothyroidism and were negative for autoimmune markers. Enhanced magnetic resonance imaging (MRI) showed pituitary enlargement. The diagnosis was lymphocytic pituitaritis. After intravenous (IV) dexamethasone treatment, full recovery occurred within 2 months. Two years later, the patient was readmitted for headache recurrence. With oral prednisone, the visual acuity in his right eye rapidly decreased to hand motion (HM) within one month. Enhanced MRI showed pituitary enlargement and a new, invasive suprasellar CNS lesion. All infection- and autoimmune-related tests were negative. The visual acuity in his right and left eye decreased to no light perception (NLP) after 6 days and 2 weeks, respectively. The biopsy results suggested GPA. After IV methylprednisolone treatment, complete remission of the symptoms occurred and was confirmed by MRI. The 15-month follow-up showed no signs of recurrence.ConclusionGPA typically affects the respiratory tract, lungs and kidneys. To date, 50 cases with pituitary involvement have been reported. Chiasmal and cranial nerve involvement leading to visual acuity impairment are common. We found 2 cases with severe visual loss resembling our case and discuss certain similarities.

Project description:Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare disease associated with vascular inflammation and multisystem organ damage. The literature reporting EGPA incidence or prevalence is limited. We performed a systematic literature review and meta-analysis to describe the incidence, prevalence, and disease burden associated with EGPA. Real-world, observational, English-language studies in MEDLINE, MEDLINE In-Process, and Embase up to 6 June, 2019, were included. A single investigator screened all identified titles/abstracts and extracted data; an additional, independent investigator repeated the screening and validated the extracted data. A random-effects meta-analysis was conducted to generate pooled estimates for EGPA incidence and prevalence. Data from 100 eligible publications were extracted (32 with incidence/prevalence data, 65 with morbidity/healthcare resource data; 3 with both types of data). Significant evidence of between-study heterogeneity for reported incidence (p = 0.0013-0.0016) and prevalence (p = 0.0001-0.0006) estimates was observed. Global and European pooled estimates (95% confidence interval) of EGPA incidence were 1.22 (0.93, 1.60) and 1.07 (0.94, 1.35) cases per million person-years, respectively; global and European pooled estimates (95% confidence interval) for EGPA prevalence were 15.27 (11.89, 19.61) and 12.13 (6.98, 21.06) cases per million individuals, respectively. The proportions of patients experiencing relapses, or who had nasal polyps or severe asthma, varied considerably across studies. EGPA healthcare resource use was high, with inpatient admissions and emergency department visits reported for 17-42% and 25-42% of patients, respectively. Our results indicate that although global and European EGPA incidence and prevalence is low, the associated disease burden is substantial. Key points • We performed a systematic literature review and meta-analysis of real-world, observational studies describing the incidence, prevalence, and disease burden associated with eosinophilic granulomatosis with polyangiitis (EGPA). • Based on meta-analysis data from 35 eligible studies reporting incidence and prevalence, the incidence and prevalence of EGPA were low (globally 1.22 cases per million person-years and 15.27 cases per million individuals, respectively). • Among the 49 studies with morbidity and/or healthcare resource data, most reported a large proportion of patients with EGPA relapses and comorbidities of nasal polyps and severe asthma. • Healthcare resource use was also high among patients with EGPA in these studies, with inpatient admissions and emergency department visits reported for 17-42% and 25-42% of patients, respectively. Taken together, these data indicate the substantial disease burden associated with EGPA.

Project description:BackgroundGranulomatosis with polyangiitis, formerly known as Wegener granulomatosis, is a necrotizing vasculitis with granulomatous inflammation that belongs to the class of antineutrophil cytoplasmic antibodies-positive diseases. It occurs in a localized and a systemic form and may present with a variety of symptoms. Involvement of the upper respiratory tract is very common, while neurologic, endocrinological, and nephrological dysfunction may occur.Case presentationWe describe the case of a 29-year-old Central European male patient presenting with severe bilateral sensorineural hearing loss, otorrhea, and one-sided facial nerve paralysis. The patient was unsuccessfully treated with i.v. antibiotics at another hospital in Berlin, and tympanic tubes were inserted. After presentation to our emergency room, he was hospitalized and further diagnostics started. Increased fluid intake and 12 kg weight gain over the last months were reported. The patient was diagnosed with granulomatosis with polyangiitis and diabetes insipidus. The patient's condition improved after treatment with rituximab.DiscussionA comprehensive PubMed search of all articles with granulomatosis with polyangiitis and diabetes insipidus was conducted to assess which combination of symptoms occurs simultaneously and whether other parts of the pituitary are commonly involved. The 39 selected articles, describing 61 patients, showed that ear-nose-throat involvement occurred most commonly, in 71% of cases. Of patients, 59% had involvement of the anterior pituitary gland, while true panhypopituitarism occurred in 13% of cases. Only one case report featured the same set of symptoms as described herein.ConclusionGranulomatosis with polyangiitis is a highly variable disease, commonly involving the upper airways, but that may present with symptoms solely related to the pituitary gland. Clinicians should have a low threshold to investigate for granulomatosis with polyangiitis in patients with therapy-resistant otorrhea. Patients may present with a complex set of symptoms, and integrating different specialists when additional symptoms occur may lead to faster diagnosis.
