Leprosy Neuropathy in a Non-Endemic Area: A Clinical and Pathological Study. Biomedicines 2023; 11:2468.

Abstract
The extent of nerve involvement in leprosy is highly variable in distribution and clinical presentation. Mononeuropathies, multiple mononeuropathies, and polyneuropathies can present both in the context of a cutaneous and/or systemic picture and in the form of pure neuritic leprosy (PNL). The differential diagnosis of leprosy neuropathy remains challenging because it is a very rare condition and, especially in Western countries, is often overlooked. We report one case of the polyneuropathic form of PNL (P-PNL) and one case of multiple mononeuropathy in paucibacillary leprosy. In both cases, the diagnosis was achieved by performing a sural nerve biopsy, which showed subverted structure, severe infiltration of inflammatory cells in nerve fascicles, granulomatous abnormalities, and the presence of alcohol-acid-resistant, Ziehl-Neelsen-positive bacilli inside the nerve bundles. Leprosy remains an endemic disease in many areas of the world, and globalization has led to the spread of cases in previously disease-free countries. In this perspective, our report emphasizes that the diagnostic possibility of leprosy neuropathy should always be taken into account, even in Western countries, in the differential diagnostic process of an acquired sensory polyneuropathy or multineuropathy and confirms that nerve biopsy remains a useful procedure in working up neuropathies with unknown etiology.

Development of pulmonary sarcoidosis in Crohn's disease patient under infliximab biosimilar treatment after long-term original infliximab treatment: a case report and literature review. BMC Gastroenterol 2021; 21:373. [PMID: 34641810 PMCID: PMC8513323 DOI: 10.1186/s12876-021-01948-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Accepted: 09/30/2021] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND Inflammatory bowel disease (IBD) is chronic inflammation of the gastrointestinal tract, although its etiology has largely been unclear. Tumor necrosis factor inhibitors (TNF-I) are effective for the treatment. Recently, biosimilars of TNF-I, such as CT-P13, have been developed and are thought to possess equal efficacy and safety to the original TNF-I. Sarcoidosis is also a systemic granulomatous disease of unknown etiology. In steroid-resistant cases of sarcoidosis, TNF-I have been reported effective for achieving resolution. However, the progression of sarcoidosis due to the TNF-I also has been reported. We herein report a case of pulmonary sarcoidosis with a Crohn's disease (CD) patient developed after a long period administration (15 years) of TNF-I. CASE PRESENTATIONS A 37-year-old woman with CD who had been diagnosed at 22 years old had been treated with the TNF-I (original infliximab; O-IFX and infliximab biosimilar; IFX-BS). Fifteen years after starting the TNF-I, she developed a fever and right chest pain. Chest computed tomography (CT) revealed clustered small nodules in both lungs and multiple enlarged hilar lymph nodes. Infectious diseases including tuberculosis were negative. Bronchoscopic examination was performed and the biopsy specimens were obtained. A pathological examination demonstrated noncaseating granulomatous lesions and no malignant findings. TNF-I were discontinued because of the possibility of TNF-I-related sarcoidosis. After having discontinued for four months, her symptoms and the lesions had disappeared completely. Fortunately, despite the discontinuation of TNF-I, she has maintained remission. CONCLUSIONS To our knowledge, this is the first case in which sarcoidosis developed after switching from O-IFX to IFX-BS. To clarify the characteristics of the cases with development of sarcoidosis during administration of TNF-I, we searched PubMed and identified 106 cases. When developing an unexplained fever, asthenia, uveitis and skin lesions in patients with TNF-I treatment, sarcoidosis should be suspected. Once the diagnosis of sarcoidosis due to TNF-I was made, the discontinuation of TNF-I and administration of steroid therapy should be executed promptly. When re-starting TNF-I, another TNF-I should be used for disease control. Clinicians should be aware of the possibility of sarcoidosis in patients under anti-TNF therapy.

Abstract
Question Is exposure to tumor necrosis factor inhibitors associated with risk of inflammatory demyelinating and nondemyelinating central nervous system events in patients with an autoimmune disease? Findings In this case-control study of 212 patients with or without inflammatory CNS events, exposure to tumor necrosis factor inhibitors was associated with an increased risk of inflammatory central nervous system events. The association was similar for both inflammatory demyelinating and nondemyelinating central nervous system events. Meaning The association observed between exposure to tumor necrosis factor inhibitor and increased risk of inflammatory demyelinating and nondemyelinating central nervous system events warrants future research to ascertain whether the association may indicate de novo inflammation or exacerbation of already aberrant inflammatory pathways. Importance Tumor necrosis factor (TNF) inhibitors are common therapies for certain autoimmune diseases, such as rheumatoid arthritis. An association between TNF inhibitor exposure and inflammatory central nervous system (CNS) events has been postulated but is poorly understood. Objective To evaluate whether TNF inhibitor exposure is associated with inflammatory demyelinating and nondemyelinating CNS events in patients with an indication for TNF inhibitor use and to describe the spectrum of those CNS events. Design, Setting, and Participants A nested case-control study was conducted using the medical records of patients with autoimmune diseases treated at 3 Mayo Clinic locations (Rochester, Minnesota; Scottsdale, Arizona; and Jacksonville, Florida) between January 1, 2003, and February 20, 2019. Patients were included if their records reported International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, diagnostic codes for US Food and Drug Administration–approved autoimmune disease indication for TNF inhibitor use (ie, rheumatoid arthritis, ankylosing spondylitis, psoriasis and psoriatic arthritis, Crohn disease, and ulcerative colitis) and diagnostic codes for inflammatory CNS events of interest. Patients were matched 1:1 with control participants by year of birth, type of autoimmune disease, and sex. Exposures TNF inhibitor exposure data were derived from the medical records along with type of TNF inhibitor, cumulative duration of exposure, and time of exposure. Main Outcomes and Measures The main outcome was either inflammatory demyelinating (multiple sclerosis and other diseases such as optic neuritis) or nondemyelinating (meningitis, meningoencephalitis, encephalitis, neurosarcoidosis, and CNS vasculitis) CNS event. Association with TNF inhibitor was evaluated with conditional logistic regression and adjusted for disease duration to determine the odds ratios (ORs) and 95% CIs. Secondary analyses included stratification of outcome by inflammatory demyelinating and nondemyelinating CNS events and by autoimmune disease (rheumatoid arthritis and non–rheumatoid arthritis). Results A total of 212 individuals were included: 106 patients with inflammatory CNS events and 106 control participants without such events. Of this total, 136 were female (64%); the median (interquartile range) age at disease onset for patients was 52 (43-62) years. Exposure to TNF inhibitors occurred in 64 patients (60%) and 42 control participants (40%) and was associated with an increased risk of any inflammatory CNS event (adjusted OR, 3.01; 95% CI, 1.55-5.82; P = .001). These results were similar when the outcome was stratified by demyelinating and nondemyelinating CNS events. Secondary analyses found the association was predominantly observed in patients with rheumatoid arthritis (adjusted OR, 4.82; 95% CI, 1.62-14.36; P = .005). Conclusions and Relevance This study found that exposure to TNF inhibitors in patients with autoimmune diseases appeared to be associated with increased risk for inflammatory CNS events. Whether this association represents de novo or exacerbated inflammatory pathways requires further research.

Abstract
A 69-year-old woman presented with appetite loss, fatigue, and a low-grade fever. She had been receiving certolizumab pegol for rheumatoid arthritis for six years. Computed tomography of the chest showed multiple micronodules in both lungs and bilateral hilar and mediastinal lymphadenopathy. An ophthalmic examination showed the findings of uveitis. Lymphocytosis with an increased CD4/CD8 ratio was seen in the bronchoalveolar lavage fluid. Video-assisted thoracoscopic biopsy specimens obtained from the right lung and a right hilar lymph node showed noncaseous epithelioid cell granulomas. Anti-tumor necrosis factor-α-induced sarcoidosis was diagnosed, and she was successfully treated with cessation of certolizumab pegol and systemic corticosteroid therapy.

Abstract
Antitumor necrosis factor-α therapy has been used effectively in treatment of many inflammatory diseases such as rheumatoid arthritis, psoriasis, psoriatic arthritis, ankylosing spondylitis, and inflammatory bowel disease. There are increasing number of paradoxical reactions associated with this therapy that are being reported. We present the case of a 63-year-old male with psoriatic arthritis maintained on adalimumab and methotrexate (previous treatment trials of prednisone and leflunomide) who developed severe symptomatic sarcoidosis in the brain, liver, and lung. Upon discontinuation of adalimumab, the symptoms resolved but the imaging findings persisted. Although the development of sarcoidosis (usually in the lung, skin, and eyes) while on antitumor necrosis factor-α therapy is increasingly reported, the brain and liver are less commonly involved but should be borne in mind by physicians when extensive granulomatous lesions develop.

Abstract
BACKGROUND Since the introduction of anti-tumour necrosis factor [TNF] therapy in inflammatory diseases, paradoxical reactions are increasingly being reported. One of these paradoxical reactions is the development of sarcoidosis-like lesions. This presentation is paradoxical since anti-TNF therapy can also be therapeutic in refractory cases of sarcoidosis. METHODS We report two cases of sarcoidosis-like lesions under anti-TNF therapy. Both were patients with inflammatory bowel disease [IBD], treated successfully with adalimumab. Next, we reviewed the literature for similar cases. Medical subject heading terms 'adalimumab', 'infliximab', 'etanercept', 'golimumab' or 'certolizumab', and 'sarcoidosis' were used to perform key word searches of the PubMed database. RESULTS We identified 90 reported cases of sarcoidosis-like lesions, which developed during anti-TNF therapy. In most cases, the anti-TNF drug involved was etanercept. The median age was 43 years and there was a predominance of female patients. The underlying disease was rheumatoid arthritis in most cases, followed by ankylosing spondylitis and psoriasiform arthritis. In six cases, the underlying disease was IBD. In 71 cases there was at least a partial resolution by discontinuation of the anti-TNF treatment, initiation of steroids or both. Re-initiation of anti-TNF therapy gave relapse in seven out of 20 cases. CONCLUSION Sarcoidosis-like lesions are increasingly reported during anti-TNF treatment. Vigilance is appropriate when patients present with symptoms compatible with sarcoidosis.

Abstract
There have been recent reports of sarcoid-like granulomatosis development following the administration of tumor necrosis factor (TNF) inhibitors. To date, only four cases of neurosarcoidosis have been reported in association with TNF inhibitors, two of which were attributed to etanercept. We present the first case of etanercept-induced neurosarcoidosis involving multiple cranial neuropathies, including the trigeminal, facial, and vestibulocochlear nerves, while also highlighting the differential diagnoses of multiple cranial neuropathies and the association of TNF inhibitors and neurosarcoidosis.

Abstract
There are only three cases in the literature that describe development of neurosarcoidosis in a patient who is on tumour necrosis factor α inhibitors. We describe a case of a 33-year-old woman with a history of juvenile rheumatoid arthritis and refractory uveitis (with previous treatment trials of adalimumab, infliximab, mycophenolate, methotrexate) who had been stable for 2 years on etanercept. She was diagnosed with biopsy-proven systemic sarcoidosis with meningeal and parenchymal neurosarcoidosis. She was switched to infliximab and methotrexate, with clinical and imaging improvements. This is a case that demonstrates the difficulty of choosing tumour necrosis factor α (TNF-α) inhibitors when treating patients with multiple clinical autoimmune entities. It is also a case where a change in the mechanism of TNF-α inhibition pathway can still be used to treat refractory sarcoidoisis and rheumatoid arthritis. It is still unclear what the exact difference between the TNF-α blockers and their neurological complications is, and who the patients at risk of developing neurological complications are.

Abstract
Background TNFα blockers have drastically improved rheumatoid arthritis prognosis by preventing joint destruction in DMARD resistant patients. Altering cytokine balance in immune diseases may expose to paradoxical adverse events. Case presentation We present the case of a 40-year-old woman, with a confirmed erosive and seropositive RA, successfully treated by TNFα blocker (etanercept) for seven years, and who developed a severe neurosarcoidosis. She had lymphocytic meningitis, bilateral peripheral facial paralysis and anosmia, associated with bilateral hilar lymph nodes, papilloedema, anterior uveitis and elevated serum angiotensin-converting enzyme level. Magnetic resonance imaging showed a bilateral thickening of the Gasser’s ganglia walls and enhanced signal of the vestibulocochlear, the facial and the proximal portion of trijeminal nerves. Conclusion This case raised the issue of the imputability of etanercept in the development of neurosarcoidosis. Neurological symptoms onset in patients on TNFα blockers should lead to exclude infections, induced lupus but also paradoxical neurosarcoidosis.
