Introduction: Fibromyalgia (FM) prevalence is much higher in patients with other rheumatic diseases than in the general population. This leads to increase in the perceived disease activity scores and prevents patients from reaching remission. Elucidating the pathogenesis of such “secondary” FM can help alleviate some unmet needs in these diseases. Methods: MEDLINE and Scopus databases were searched for a scoping review for hypothesis generation regarding the genesis of secondary FM. Results: FM has been postulated to be due to cytokine dysfunction, neurogenic neuroinflammation, stress, including social defeat, sleep disturbances, sympathetic overactivity, and small fibre neuropathy. These factors increase in most autoimmune and autoinflammatory diseases. Further the evidence for the role of these factors in the pathogenesis of FM is seems strong. Metabolic syndrome and mitochondrial dysfunction are also associated with FM, but it is difficult to distinguish between cause and effect. Conclusion: FM is the common phenotype arising from the amalgamation of various aetiologies. Recruitment or amplification of the above 6 factors by various rheumatic diseases may thus lead precipitation of secondary FM in susceptible individuals.

In the current Thematic Issue of Current Vascular Pharmacology (CVP), entitled “Systemic Autoimmune Rheumatic Diseases and Cardiology”, presented in two parts, Part 1 and Part 2, review articles are included from specialists in cardiology, rheumatology, immunology and related fields. These reviews discuss the cardiovascular complications of the main systemic Autoimmune Rheumatic Diseases (ARDs). For example, the underlying pathogenetic mechanisms, the role of cardiovascular imaging and recommendations for prevention and management. These articles place inflammation as the key process, linking cardiovascular complications with ARDs. From all these reviews, the conclusion is the need for collaboration between the disciplines of Rheumatology and Cardiology to establish the emerging field of Cardio- Rheumatology. This will aid to fine-tune risk stratification and optimize preventive strategies and pharmacological therapies for patients with ARDs.

Abstract BackgroundThe clinical characteristics and outcomes of small fibre neuropathy (SFN) in Chinese patients with type 2 diabetes have not been thoroughly described, and we investigated metabolic and neurological indexes and the prognosis of type 2 diabetic patients based on skin biopsy. MethodsThirty-four healthy Chinese volunteers were recruited for skin biopsy to establish the reference range of intraepidermal nerve fibre density (IENFD). Eighty-nine patients with type 2 diabetes from the Department of Endocrinology at Nanjing Drum Tower Hospital between December 2015 and April 2020 were included in the final study. Metabolic and neurological indexes were evaluated at baseline. Diabetic cardiovascular autonomic function was tested through cardiovascular autonomic reflex tests (CARTs). Seventeen pure SFN subjects and 9 mixed diabetic polyneuropathy (DPN) subjects were reassessed after the follow-up. ResultsLevels of HbA1c and postprandial blood glucose were lower (P=0.005 and P=0.041, respectively), while postprandial C-peptide and insulin were higher (P=0.001 and P=0.019, respectively) in the pure SFN group than in the mixed DPN group. Regarding the CARTs, the mixed DPN group obtained the highest score, indicating the worst cardiovascular autonomic neuropathy (CAN). Among the four CART items, postural BP change was lower while deep breathing max-min was higher in the pure SFN group than in the mixed DPN group (P=0.023 and P=0.040, respectively). A partial correlation showed that there was a negative correlation between IENFD of the distal leg and CART scores (r=-0.513, P=0.001) after adjusting for age and duration of diabetes. Only vitamin B12 (p=0.028) and motor nerve conduction velocity (MCV) of the common peroneal nerve (p=0.045) were increased in the 17 patients with pure SFN after the follow-up. However, MCVs of the common peroneal nerve (p=0.025) and tibial nerve (p=0.047) were decreased at the final visit in the mixed DPN group. ConclusionsBetter islet function and cardiovascular autonomic function were observed in patients with pure SFN compared with mixed DPN. CART scores were negatively correlated with IENFD in the distal leg even after adjusting for age and duration of diabetes. The metabolic and neurological indexes remained relatively stable in the follow-up of pure SFN subjects.

Pain in rheumatic diseases is primarily due to mechanical or inflammatory mechanism, but neuropathic pain (NP) component is also occurring in many conditions and is probably underdiagnosed. The purpose of this article is to provide an overview of prevalence, pathophysiological and currently available treatment of NP in rheumatic diseases. When associated with clinical evaluation assessing neurological clinical signs and neuroanatomical distribution, Douleur Neuropathique 4 Questions, painDETECT, Leeds assessment of neuropathic symptoms and signs and Neuropathic Pain Questionnaire can detect NP component. Inflammatory or connective diseases, osteoarthritis, back pain or persistent pain after surgery are aetiologies that all may have a neuropathic component. Unlike nociceptive pain, NP does not respond to usual analgesics such as paracetamol and non-steroidal anti-inflammatory drugs. Entrapment neuropathy, peripheral neuropathy or small-fibre neuropathy are different aetiologies that can lead to NP. A part of the pain labelled neuropathic is rather nociplastic, secondary to a central sensitisation mechanism. Identifying the right component of pain (nociceptive vs neuropathic or nociplastic) could help to better manage pain in rheumatic diseases with pharmacological and non-pharmacological treatments.

Abnormal Sleep

There is a tight association between mood and sleep as disrupted sleep is a core feature of many mood disorders. The paucity in available animal models for investigating the role of sleep in the etiopathogenesis of depression-like behaviors led us to investigate whether prior sleep disturbances can predict susceptibility to future stress. Hence, we assessed sleep before and after chronic social defeat (CSD) stress. The social behavior of the mice post stress was classified in two main phenotypes: mice susceptible to stress that displayed social avoidance and mice resilient to stress. Pre-CSD, mice susceptible to stress displayed increased fragmentation of Non-Rapid Eye Movement (NREM) sleep, due to increased switching between NREM and wake and shorter average duration of NREM bouts, relative to mice resilient to stress. Logistic regression analysis showed that the pre-CSD sleep features from both phenotypes were separable enough to allow prediction of susceptibility to stress with >80% accuracy. Post-CSD, susceptible mice maintained high NREM fragmentation while resilient mice exhibited high NREM fragmentation, only in the dark. Our findings emphasize the putative role of fragmented NREM sleep in signaling vulnerability to stress.

This article focuses on the main contemplative principles of the ‘Heart Essence’ (sNying thig), a Tibetan Buddhist tradition that is characterized by a vision of non-duality and primordial wholeness. Due to this vision, which asserts an original reality that is not divided into perceiving subject and perceived object, the ‘Heart Essence’ advocates a contemplative practice that undermines the usual intuitions of temporality and enclosed selfhood. Hence, unlike the common principles of intentional praxis, such as deliberate concentration and gradual purification, the ‘Heart Essence’ affirms four contemplative principles of non-objectiveness, openness, spontaneity and singleness. As these principles transcend intentionality, temporality, and multiplicity, they are seen to directly disclose the nature of primordial awareness, in which the meanings of knowing and being are radically transformed. Therefore, the article will also consider the role of these non-dual contemplative principles in deeply changing our understanding of being and knowing alike.

De Gaulle

This article highlights the role of Charles de Gaulle in the history of united post-war Europe, his approaches to the internal and foreign French policies, also vetoing the membership of the United Kingdom in the European Community. The authors describe the emergence of De Gaulle as a politician, his uneasy relationship with Roosevelt and Churchill during World War II, also the roots of developing a “nationalistic” approach to regional policy after the end of the war. The article also considers the emergence of the Common Agricultural Policy (hereinafter - CAP), one of Charles de Gaulle’s biggest achievements in foreign policy, and the reasons for the Fouchet Plan defeat.
