Abstract
PURPOSE Bone diseases account for an enormous cost burden on health systems. Bone disorders are considered as age-dependent diseases. The aging of world population has encouraged scientists to further explore the most effective preventive modalities and therapeutic strategies to overcome and reduce the high cost of bone disorders. Herein, we review the current evidence of melatonin's therapeutic effects on bone-related diseases. METHODS This review summarized evidences from in vitro, in vivo, and clinical studies regarding the effects of melatonin on bone-related diseases, with a focus on the molecular mechanisms. Electronically, Scopus and MEDLINE®/PubMed databases were searched for articles published on melatonin and bone-related diseases from inception to June 2023. RESULTS The findings demonstrated that melatonin has beneficial effect in bone- and cartilage-related disorders such as osteoporosis, bone fracture healing, osteoarthritis, and rheumatoid arthritis, in addition to the control of sleep and circadian rhythms. CONCLUSION A number of animal and clinical studies have indicated that various biological effects of melatonin may suggest this molecule as an effective therapeutic agent for controlling, diminishing, or suppressing bone-related disorders. Therefore, further clinical studies are required to clarify whether melatonin can be effective in patients with bone-related diseases.

de Carvalho JF, Skare TL. Melatonin supplementation improves rheumatological disease activity: A systematic review. Clin Nutr ESPEN 2023; 55:414-419. [PMID: 37202076 DOI: 10.1016/j.clnesp.2023.04.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Revised: 02/20/2023] [Accepted: 04/15/2023] [Indexed: 05/20/2023]
Abstract
BACKGROUND Melatonin is a pineal hormone with a complex role. It is linked to sleep, inflammatory, oxidative, and immunological processes. AIM To review the use of melatonin supplementation in rheumatological diseases. METHODS A systematic search of PubMed, Embase, and Scielo databases was performed, looking for articles on Melatonin and rheumatic diseases published between 1966 and August 2022. RESULTS Thirteen articles were identified: in fibromyalgia (n = 5 articles), rheumatoid arthritis (n = 2), systemic sclerosis (n = 1), systemic lupus erythematosus (n = 1) and osteoporosis/osteopenia (n = 3) and osteoarthritis (n = 1). There were positive results of melatonin administration in fibromyalgia, osteoarthritis, and osteoporosis/osteopenia but not in rheumatoid arthritis and lupus. The drug was well tolerated with mild side effects. CONCLUSION This review shows the efficacy of Melatonin in some rheumatic diseases. However, new studies are needed to elucidate the real role of this treatment in rheumatology.

Abstract
BACKGROUND The neuroendocrine system is known to influence immunity, but the precise interactions between different hormones and autoimmune disorders remain obscure. AIMS The present study aimed to investigate the role of daily serum melatonin concentrations in the development of systemic lupus erythematosus (SLE) in women. STUDY DESIGN Case-control study. METHODS One-hundred and eleven SLE female patients and 46 healthy women were included in the study. Daily serum melatonin levels were investigated in all participants. RESULTS SLE patients showed significantly lower daily melatonin levels in comparison to healthy women during the short photoperiod (17.75±7.13 pg/mL [16.05] vs. 21.63±6.60 pg/mL [20.10], p=0.012). Hormone concentrations were inversely related to the SLE activity index (SLEDAI) (r= -0.268, p=0.004), but they did not correlate to any particular American College Rheumatology (ACR) criterion (p>0.05 for all). CONCLUSION Daily melatonin levels were decreased in women with systemic lupus erythematosus and correlated inversely to the activity of the autoimmune disease. Further studies are needed to clarify the importance of the pineal and extrapineal melatonin secretion in patients with systemic lupus erythematosus as well as the interrelations between hormones and autoimmunity.

Abstract
Circumventricular organs (CVOs) are specialized brain structures located around the third and fourth ventricles. They differ from the rest of the brain parenchyma in that they are highly vascularised areas that lack a blood-brain barrier. These neurohaemal organs are classified as "sensory", when they contain neurons that can receive chemical inputs from the bloodstream. This review focuses on the sensory CVOs to describe their unique structure, and their functional roles in the maintenance of body fluid homeostasis and cardiovascular regulation, and in the generation of central acute immune and febrile responses. In doing so, the main neural connections to visceral regulatory centres such as the hypothalamus, the medulla oblongata and the endocrine hypothalamic-pituitary axis, as well as some of the relevant chemical substances involved, are described. The CVOs are vulnerable to circulating pathogens and can be portals for their entry in the brain. This review highlights recent investigations that show that the CVOs and related structures are involved in pathological conditions such as sepsis, stress, trypanosomiasis, autoimmune encephalitis, systemic amyloidosis and prion infections, while detailed information on their role in other neurodegenerative diseases such as Alzheimer's disease or multiple sclerosis is lacking. It is concluded that studies of the CVOs and related structures may help in the early diagnosis and treatment of such disorders.

Abstract
Inflammatory and immune mediated diseases of the nervous system are reflected by a broad spectrum of different clinical deficits. The reason for this is that inflammation may affect any part of the nervous system. Nevertheless, certain regions in the brain and spinal cord are more frequently affected than others. The topographical distribution of inflammatory lesions in the nervous system depends upon a large variety of different factors, which are different in the various infectious and autoimmune diseases. Aim of this short review is to discuss the main factors determining lesional topography in brain inflammation and to illustrate these patterns of tissue injury with clinical examples.

Abstract
Sera from patients with neuropsychiatric lupus (NP lupus) were screened for antibodies to mouse choroid plexus cell line ECPC-4 by Western blotting. A 29-kDa protein band detected in NP lupus sera was identified as triosephosphate isomerase (TPI). Using Western blotting with TPI, TPI was confirmed as the reactive molecule in sera (6 of 14 samples) and in cerebrospinal fluids (1 of 2 samples) of patients with NP lupus. Enzyme-linked immunosorbent assay with TPI showed that the serum anti-TPI antibody index of 89.8 (SD, 70.1) in NP lupus group was significantly higher than in systemic lupus erythematosus without NP manifestations, 34.6 (29.6); scleroderma, 38.2 (39.9); polymyositis/dermatomyositis, 42.1 (51.5); and control, 31.7 (27.4) groups (p<0.02). Sensitivity, specificity, and positive and negative likelihood ratios of serum anti-TPI antibody index for NP lupus were 42.9%, 94.7%, 8.1%, and 0.6%, respectively. These results suggest that anti-TPI antibodies are closely associated with NP lupus.

Abstract
The aim of this study was to investigate the effect of increased number and frequency of vaccination on immune complex deposition in the choroid plexus and glomeruli of non-nephrectomized and unilateral nephrectomized mice. Fifty-five non-nephrectomized, 40 nephrectomized, and 7 control Swiss albino mice were used. Half of each group was vaccinated only with diphtheria-tetanus and the other half with multiple vaccines, which are used in pediatric practice. Each group was divided into subgroups, which were vaccinated with increasing frequency. No immune deposits were detected in the choroid plexus of any vaccinated mice. There were immune deposits in glomeruli in 2 of 55 (3.6%) of the non-nephrectomized and in 3 of 40 (7.5%) of the nephrectomized mice (P=0.199). The difference between the diphtheria-tetanus and multiple vaccine groups in non-nephrectomized (P=0.236) and nephrectomized (P=1.000) mice was not significant. A significant positive correlation between increased frequency of vaccination and glomerular immune complex deposition 8 weeks after the last immunization was detected in the multiple vaccine group of nephrectomized mice (P=0.048, r=0.447). Our results suggest that the large number and frequent doses of vaccines would not lead to immune complex deposition in choroid plexus and do not significantly increase the deposition of immune complexes in glomeruli in unilateral nephrectomized mice compared with non-nephrectomized mice.

Abstract
The brain, with the exception of the choroid plexuses and circumventricular organs, is partially protected from the invasion of blood-borne chemicals by the specific morphological properties of the cerebral micro-vessels, namely, the tight junctions of the blood-brain barrier. Recently, several enzymes that are primarily involved in hepatic drug metabolism have been shown to exist in the brain, albeit at relatively low specific activities. In the present study, the hypothesis that these enzymes are located primarily at blood-brain interfaces, where they form an "enzymatic barrier," is tested. By using microdissection techniques or a gradient-centrifugation isolation procedure, the activities of seven drug-metabolizing enzymes in isolated microvessels, choroid plexuses, meningeal membranes, and tissue from three circumventricular organs (the neural lobe of the hypophysis, pineal gland, and median eminence) were assayed. With two exceptions, the activities of these enzymes were higher in the three circumventricular organs and cerebral microvessel than in the cortex. Very high membrane-bound epoxide hydrolase and UDP-glucuronosyltransferase activities (approaching those in liver) and somewhat high 7-benzoxyresorufin-O-dealkylase and NADPH-cytochrome P-450 reductase activities were determined in the choroid plexuses. The pia-arachnoid membranes, but not the dura matter, displayed drug-metabolizing enzyme activities, notably that of epoxide hydrolase. The drug-metabolizing enzymes located at these nonparenchymal sites may function to protect brain tissue from harmful compounds.

Abstract
The level of cerebrospinal fluid (CSF) protein is elevated in diseases and disease models that are associated with circulating immune complexes such as serum sickness. Circulatory immune complexes are known to deposit in the basal lamina of fenestrated capillaries and may, as a result, affect both capillary bed and parenchymal function. Since the brain has both fenestrated and unfenestrated capillaries and immune complexes deposit to a varying extent in the fenestrated capillaries in chronic serum sickness, cerebral capillary permeability to protein may be altered in some brain areas and lead to the elevation of CSF proteins. In addition various other cerebrovascular and metabolic functions may also be affected by this condition. In this study either radio-iodinated serum albumin (RISA) or 2-[14C]deoxyglucose (14C-2DG) was intravenously injected into control Wistar rats and Wistar rats with chronic serum sickness; subsequently the tissue levels of radioactivity were measured by quantitative autoradiography in 4 brain areas with fenestrated capillaries and 11 brain areas with unfenestrated capillaries. The 2-min distribution of RISA, which demarcates the volume of circulating plasma in perfused microvessels and is generally proportional to local plasma flow, was the same in control and experimental rats. The passage of RISA from blood into brain over 30 min was negligible in both groups; thus cerebral capillary permeability to albumin was not detectably increased in any of these 15 brain areas by chronic serum sickness. The rate of local cerebral glucose utilization, an indicator of local metabolic and neural activity, was calculated from the 14C-2DG data and was virtually identical in control and experimental rats.(ABSTRACT TRUNCATED AT 250 WORDS)
