Abstract
Peripheral neuropathies are surprisingly common and can be associated with a number of conditions, including rheumatological diseases. Whether the co-existence of peripheral neuropathies with rheumatological disorders is coincidental or related to a common pathogenic mechanism, these disabling conditions can affect the outcome of rheumatological patients and should be targeted with specific treatment. The clinical presentation of peripheral neuropathy can be multifaceted and difficult to recognize in polysymptomatic patients. However, physicians adopting state-of-art diagnostic strategies, including nerve imaging, may improve the detection rate and management of neuropathies. In particular, a diagnostic approach relying exclusively on clinical history and nerve conduction studies may not be sufficient to disclose the etiology of the nerve damage and its anatomical location and thus requires integration with morphological studies. High-Resolution Ultrasound (HRUS) is increasingly adopted to support the diagnosis and follow-up of both joint disorders in rheumatology and peripheral neuropathies of different etiologies. In this review, the different types of nerve disorders associated with the most common syndromes of rheumatological interest are discussed, focusing on the distinctive sonographic features.

Abstract
Purpose of review: To discuss and summarize recent findings in peripheral neuropathy (PN) related to connective tissue diseases (CTD) including its prevalence, clinical manifestations, pathogenesis, diagnosis and treatment. Recent findings: Although PN is a common complication in CTD and has been well studied, recent research has shown that PN is more diverse and frequent in different subtypes of CTD than was expected. The incidence of PN in Sjögren’s syndrome and rheumatoid arthritis (RA) varies according to different disease subtypes, and the pathogenesis of neuropathic pain in different subtypes of eosinophilic granulomatosis with polyangiitis (EGPA) may also differ. Neurogenic inflammation, autoantibody-mediated changes, ischemia of the vascular wall and metabolic mechanisms have been shown to contribute to the pathogenesis of PN in CTD. Moreover, allergic inflammation has been recently identified as a possible new mechanism producing peripheral neuropathic pain associated with MPO-ANCA negative EGPA patients. Glucocorticoids are routinely used to relieve pain caused by PN. However, these steroids may cause hyperalgesia, exacerbate neuropathic pain, and activate the early phase of pain induction and produce hyperalgesia. Recently, neuroactive steroids, such as progesterone, tetrahydroprogesterone and testosterone, have been shown to exert protective effects for several PN symptoms, and in particular neuropathic pain. Neuroactive steroids will be an interesting topic for future research into PN in CTD. Summary: It is essential for the diagnosis and treatment of PN in CTD to be updated. Timely diagnosis, appropriate treatments, and multidisciplinary care are essential to minimize morbidity and decrease the risk of permanent neurologic deficits. Further studies are needed to guide diagnosis and treatment.

Carpal Tunnel Syndrome in Autoimmune Rheumatic Diseases and Inflammatory Bowel Diseases: Retrospective Population Cohort Study. Am J Phys Med Rehabil 2021; 100:760-765.

Abstract
OBJECTIVE The relationship between autoimmune rheumatic diseases, inflammatory bowel diseases, and carpal tunnel syndrome is unclear. We aimed to survey the occurrence and characteristics of carpal tunnel syndrome in autoimmune rheumatic diseases and inflammatory bowel diseases, compared with the general population. METHODS We used the Longitudinal Health Insurance Database 2015 from Taiwan's National Health Insurance Research Database. Patients diagnosed with autoimmune rheumatic diseases/inflammatory bowel diseases were identified. The incidence rates and surgical rates of carpal tunnel syndrome among individual diseases were calculated. The hazard ratios when compared with age and sex matched, and 1:1 ratio control groups were surveyed. RESULTS A total of 2591 women and 701 men were identified. The incidence rate of carpal tunnel syndrome was highest in Crohn disease (1001 per 100,000 person-years, 95% confidence interval = 0-2747), followed by scleroderma and Sjögren syndrome. The incidence rate in the control group was 571 per 100,000 person-years (95% confidence interval = 314-829). Significantly increased adjusted hazard ratios were seen in Sjögren syndrome (1.44, 95% confidence interval = 1.09-1.90) and rheumatic arthritis (1.33, 95% confidence interval = 1.05-1.70). The overall surgical rate was 0.2% in patients with autoimmune rheumatic diseases/inflammatory bowel diseases and 0.3% in the control group, without a significant difference (P = 0.85). CONCLUSIONS Patients with Sjögren syndrome and rheumatic arthritis are susceptible to carpal tunnel syndrome. Patients with autoimmune rheumatic diseases/inflammatory bowel diseases have similar surgical rates as general population.

Abstract
Carpal tunnel syndrome (CTS) is the most common mononeuropathy in patients with end-stage renal disease (ESRD). The association between chronic inflammation and CTS in hemodialysis (HD) patients has rarely been investigated. HD patients with a high normalized protein catabolic rate (nPCR) and low serum albumin level likely have adequate nutrition and inflammation. In this study, we assume that a low serum albumin level and high nPCR is associated with CTS in HD patients. We recruited 866 maintenance hemodialysis (MHD) patients and divided them into 4 groups according to their nPCR and serum albumin levels: (1) nPCR <1.2 g/kg/d and serum albumin level <4 g/dL; (2) nPCR ≥1.2 g/kg/d and serum albumin level <4 g/dL; (3) nPCR <1.2 g/kg/d and serum albumin level ≥4 g/dL; and (4) nPCR ≥1.2 g/kg/d and serum albumin level ≥4 g/dL. After adjustment for related variables, HD duration and nPCR ≥1.2 g/kg/d and serum albumin level <4 g/dL were positively correlated with CTS. By calculating the area under the receiver-operating characteristic curve, we calculated that the nPCR and HD duration cut-off points for obtaining the most favorable Youden index were 1.29 g/kg/d and 7.5 years, respectively. Advance multivariate logistic regression analysis revealed that in MHD patients, nPCR ≥1.29 g/kg/d and serum albumin <4 g/dL, and also HD duration >7.5 years were associated with CTS. A high nPCR and low serum albumin level, which likely reflect adequate nutrition and inflammation, were associated with CTS in MHD patients.
