Dehydroepiandrosterone (DHEA) Supplementation in Rheumatic Diseases: A Systematic Review.

Background: Dehydroepiandrosterone (DHEA) is an adrenal hormone used to treat rheumatic conditions such as systemic lupus erythematosus (SLE), Sjogren's syndrome (SS), rheumatoid arthritis (RA) with controversial results. Aim: To review the results of DHEA use in rheumatic diseases. Methods: PubMed, Scielo, Scopus, and Embase databases were systematically searched for articles on the treatment of rheumatic diseases with DHEA between 1966 and April 2023. Results: Twenty-one studies were identified: 13 in SLE, 5 in SS, 2 in RA, and 1 in fibromyalgia. DHEA use in SLE has shown a mild to moderate effect on disease activity, a positive effect on bone mineral density (BMD), and improved fatigue. The studies on SS showed a decrease in symptoms of dry mouth, but its performance did not differ from placebo in disease activity. In RA, a questionable effect on disease activity was noted. The only study on fibromyalgia failed to show any improvement. The drug was well tolerated; mild androgenic effects were the most common complaints. Conclusion: DHEA seems to have a place in SLE treatment, where it improves BMD and disease activity. The use in RA, SS, and FM is questionable.

Successful Treatment of a Fibromyalgia Patient Using a Homeopathic Preparation of Cannabis sativa.

BACKGROUND: Homeopathy has been used in observational and controlled studies to treat patients with fibromyalgia (FM), but none has previously used the remedy Cannabis sativa. CASE HISTORY: A 51-year-old female patient presenting with diffuse pain and sleep disorder was diagnosed with FM using the relevant American College of Rheumatology criteria. She reported having 18 tender points, a pain score (visual analog scale, VAS) of 9.0, and a well-being VAS of 5.0. She was prescribed Cannabis sativa 6 cH, five drops sublingually thrice a day. RESULTS: After 2 months, she returned asymptomatic, with 0 tender points, pain VAS of 0, and well-being VAS of 9.0. The Modified Naranjo Criteria for Homeopathy score was equal to +9, suggesting the clinical outcome was causally attributable to the medicine prescribed. CONCLUSION: This case study reveals the positive role of homeopathic treatment in FM. Studies using a randomized controlled design, including pragmatic trials to determine treatment effectiveness in real-world clinical practice, are indicated in this field.

Primary antiphospholipid syndrome with and without limb ischemia: A retrospective observational study.

OBJECTIVE: To compare clinical and laboratory data obtained from patients with primary Antiphospholipid Syndrome (PAPS) with and without limb ischemia (LI). METHODS: A transverse study with 66 (83.3% female) PAPS patients was performed. All data were evaluated. Patients were subdivided into one of two groups: PAPS with LI and PAPS without LI and compared. RESULTS: Sixty-six primary APS were selected. PAPS with LI group exhibited a longer disease duration (p = .012) and more arterial events (p = .002). A lower frequency of venous events was observed in PAPS with LI (p = .007), and deep venous thrombosis (p = .016). Furthermore, PAPS with LI patients had more deficiency of protein C of coagulation (p = .015) than the others. CONCLUSION: PAPS and LI have a distinct clinical and laboratory spectra from those without LI and it is characterized by an increased frequency of protein C deficiency, and a lower frequency of venous events, deep venous thrombosis and IgM anticardiolipin.

Resveratrol in Rheumatological Diseases: A Systematic Review.

Resveratrol is an antioxidant with anti-inflammatory and cell-protective properties. The aim of our article is to review the use of resveratrol in rheumatic diseases. PubMed/Medline, Embase, and Scielo were screened for articles on resveratrol and rheumatic diseases in the period between of January 1966 and March 2023. Five articles were depicted, including 481 patients. The included diseases were osteoarthritis (n=3), rheumatoid arthritis (n=1), and Takayasu arteritis (n=1). The age varied from 32 to 58.2 years, and the female gender ranged from 62% to 74% in the studies. Disease duration ranged from 3.5 ± 3.2 to 9.4 ± 5.8 years. The resveratrol dosage went from 250 mg to 1000 mg/day. All those articles demonstrated improvements in the diverse rheumatic diseases, including pain intensity, function, disease activity (DAS 28), swelling joints, and reduced inflammation markers (erythrocyte sedimentation rate, C-reactive protein, interleukinIL-1, IL-6, and tumor necrosis factor). No side effects were detected in all studies. In conclusion, resveratrol seems to be a safe therapy for various rheumatic diseases, although the evidence is very limited. The improved subjective and objective complaints and laboratory parameters are promising. However, there is a need to reconfirm, reproduce, and investigate the topic in more extensive, well-controlled, double-blind, cross-over studies.

Melatonin supplementation improves rheumatological disease activity: A systematic review.

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.

Low-Dose Naltrexone in Rheumatological Diseases.

Background: Naltrexone has been approved for alcohol and opioid abuse by the FDA. At low-dose naltrexone (LDN) has been used in several diseases including chronic pain and autoimmune conditions, including rheumatic disorders. Aim: To review the use of LDN in rheumatic diseases: systemic sclerosis (SSc), dermatomyositis (DM), Sjögren's syndrome (SS), rheumatoid arthritis (RA), and fibromyalgia (FM). Methods: PubMed and Embase databases were searched for articles on LDN and rheumatic diseases between 1966 and August 2022. Results: Seven studies in FM have been identified: in this disease LDN has showed beneficial effects on pain and well-being. In SS, two articles with 3 cases description showed that LDN may be of help in the pain treatment. LDN relieved pruritus in scleroderma (a case description with a series of 3 patients) and dermatomyositis (description of 3 patients in two articles). In RA a study using Norwegian Prescription Database showed that LDN was associated to reduction in the use of analgesic and DMARDs. No serious side effects were detected. Conclusion: This review shows that LDN is a promising and safe therapy to be used in some rheumatic disease. However, the data is limited and needs to be reproduced in larger studies.

Prevalence of Metabolic Syndrome and Insulin Resistance in Adult Patients with Acne: Association with Traditional Cardiovascular Risk Factors and Acne Severity.

Introduction: Acne is a chronic inflammatory disease that affects the pilosebaceous unit, and there are conflicting evidences regarding its association with metabolic syndrome (MS) and insulin resistance (IR). Methods: A cross-sectional study was performed with 162 acne patients, over 20 years of age, matched for age and sex with 78 healthy controls without acne. The measured parameters included waist circumference (WC), body mass index (BMI), systolic blood pressure, diastolic blood pressure, fasting blood glucose, fasting insulin, high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides (TG), and total cholesterol. Acne severity was determined according to the Global Acne Grading System. The criteria used for the diagnosis of MS were those of the Harmonizing the Metabolic Syndrome Statement, adjusted for South Americans, and the IR was calculated using the HOMA-IR. Results: The prevalence of MS was significantly higher in cases, compared to controls (12.3% vs. 2.6%, P = 0.014), as was the prevalence of IR (11.7% vs. 3.8%, P = 0.047). In addition, MS and IR showed a positive correlation with the degree of acne severity (P = 0.011 and P = 0.021, respectively). HDL levels were significantly lower in cases (P = 0.012) and showed an association with acne severity (P = 0.038). In the logistic regression model, the risk factor that independently influenced both MS and IR in patients with acne was the WC (P = 0.001). Conclusions: Adults with acne, especially the most severe cases, are significantly more likely to have MS, IR, and lower HDL levels, compared to controls without acne.

Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) with postural orthostatic tachycardia syndrome after silicone breast implantation: Case report.

This study illustrates two patients who developed autoimmune/inflammatory syndrome induced by adjuvants (ASIA) with postural orthostatic tachycardia syndrome (POTS) after silicone breast implant (SBI) and improved after SBI extraction.

Lymphocytic Interstitial Pneumonia Associated with Sjögren Syndrome: Case-Based Review.

BACKGROUND: Few studies have described lymphocytic interstitial pneumonia (LIP) in Sjögren's syndrome (SS). We aimed to analyze the clinical, therapeutic, and outcome of patients with SS and LIP. METHODS: We searched for articles in PubMed/MEDLINE, LILACS, SciELO, and Cochrane from 1966 to 2020, in English, Spanish, French, Chinese, and Japanese literature had an English summary about LIP and SS. The keywords were "Sjögren syndrome" and "Lymphocytic interstitial pneumonia." Additionally, we report a patient with SS and LIP. RESULTS: 27 patients with SS and LIP were found. The age range ranged from 14 to 73 years old, with only 3 male patients, with a predominance of LIP cases in patients with primary SS (22/27). In the following case, the LIP preceded SS by 2 years; in the other 26 patients, SS preceded it. The majority presented dyspnea, mainly on exertion, followed by a dry cough. Lung biopsy was performed in 10 studies. Therapy varied from the use of clinical observation, corticosteroids alone, or associated with immunosuppressants. Most studies have shown improvement or stabilization of the pulmonary condition after therapy (13/16 studies). CONCLUSION: This article reviews cases of lymphocytic interstitial pneumonia associated with Sjögren syndrome and shows a good outcome with adequate treatment. It emphasizes that early LIP diagnosis in patients with Sjogren Syndrome may be determined using lung computed tomography.

Nutraceuticals improved physical performance in an ankylosing spondylitis patient reaching 200 km of cycling per week.

BACKGROUND: To describe for the first time a patient with ankylosing spondylitis (AS) successfully treated with cycling, and marked improvement of his physical performance after nutraceuticals. CASE REPORT: A 63-year-old male with a diagnosis of AS. He received several kinds of drugs. He practices physical activity since he was a teenager, and cycling 10 years ago reaching 30 km/week. He had excellent disease control with cycling, and all medications were stopped. His physical examination demonstrates limitations of the lumbar and cervical spine movements. X-ray confirmed AS. He was treated with a nutraceutical supplementation and probiotics. He felt a progressive improvement in his physical performance and marked improvement of his mild residual AS clinical symptoms. After 1 year of follow up, he was doing 200 km/week by cycling. CONCLUSION: This study illustrates a patient with AS under control, who could get a higher performance cycling after nutraceuticals supplementation.

Lidocaine in fibromyalgia: A systematic review.

BACKGROUND: Fibromyalgia (FM) patients are treated with antidepressants, and in most cases, these drugs lose efficacy or present side effects. Intravenous lidocaine (IL) is an anesthetic drug used in some FM trials. AIM: To systematically review the safety and efficacy of IL in FM patients. METHODS: To systematically search PubMed for articles in English, Spanish, and Japanese with English Abstracts on FM and lidocaine between 1966 and February 2021. This study was registered at PROSPERO. RESULTS: We found only ten articles published in this field, with a total of 461 patients. Females predominated varying from 95% to 100% in the studies. Age varied from 40.9 to 55 years old. Disease duration varied from 1 mo to 6.4 years. Lidocaine dose varied from 2 to 7.5 mg/kg via intravenous infusion. Follow-up period varied from 65.7 to 90 days. Regarding outcomes, most studies used the visual analogue scale (VAS) for pain; before short-term lidocaine administration, VAS was between 6.1 and 8.1 and after treatment was between 1.7 and 4.5 mm. Concerning long term lidocaine, VAS varied from 30% to 35.4% after lidocaine infusion. Side effects were observed in 0% to 39.6% of cases, they were usually mild or moderate. CONCLUSION: This study demonstrates the short-term effectiveness and safety of intravenous lidocaine in FM patients. However, more studies, including long-term follow-up, are still needed.

Avaliação da transferência materno-infantil de anticorpos em pacientes com síndrome antifosfolípide / Evaluation of maternal-child antibody transfer of patients with antiphospholipid syndrome

Introdução: a síndrome antifosfolípide (SAF) é caracterizada por eventos trombóticos e perdas gestacionais de repetição sendo considerada a trombofilia adquirida mais comum. Objetivo: realizar uma revisão narrativa da passagem transplacentária de anticorpos em pacientes com SAF. Metodologia: revisão narrativa da literatura. Resultados: quando não está associada a alguma doença do tecido conectivo é dita primária e quando em associação com lúpus eritematosos sistêmico é dita secundária. A morbidade gestacional é frequente e torna-se de importância avaliar a passagem desses anticorpos transplacentariamente, desde que existem modelos animais da síndrome com transferência passiva desses anticorpos. A passagem transplacentária de anticorpos específicos já foi determinada em estudos, os quais demonstraram baixos níveis destes anticorpos no soro materno, porém uma eficiente passagem transplacentária para o neonato. Conclusão: existem poucos estudos sobre essa passagem materno-infantil em pacientes com SAF, que são aqui revisados.

Introduction: a antiphospholipid syndrome (APS) is characterized by thrombotic events and recurrent pregnancy losses and is considered the most common acquired thrombophilia. Objective: to carry out a narrative review of the transplacental passage and antibodies in patients with APS. Methodology: narrative literature review Results: when it is not associated with any connective tissue disease, it is said to be primary and when in association with systemic lupus erythematosus it is said to be secondary. Gestational morbidity is frequent and it is important to evaluate the passage of these antibodies transplacentally, since there are animal models of the syndrome with passive transfer of these antibodies. The transplacental passage of specific antibodies has already been determined in studies, which demonstrated low levels of these antibodies in the maternal serum, but an efficient transplacental passage for the newborn. Conclusion: there are few studies on this maternal-infant passage in patients with APS, which are reviewed here.

Clinical and therapeutical features of patients with systemic lupus erythematosus associated with gastroparesis: A systematic review.

This paper aims to analyze the clinical, therapeutic, and evolutionary characteristics of patients with systemic lupus erythematosus (SLE) that is associated with gastroparesis. We have systematically researched articles published in Pubmed, MEDLINE, LILACS, and Scielo dating from 1966 to April 2020. All the researched articles are based on gastroparesis and SLE in the following literature: English, Chinese, and Japanese. We obtained five cases of SLE associated with gastroparesis. There are three case reports included and two retrospective epidemiological studies where the clinical data are not detailed. Of the case reports, all of them were females aged between 27 and 58 years. All of them showed symptoms of nausea and vomiting. Abdominal pain and weight loss were reported in the only two-third of the cases. Only one case showed early satiety. All the cases were tested positive for antinuclear antibodies and anti-dsDNA antibodies at the time of gastroparesis. In all the cases, scintigraphy was performed to check gastric emptying. This is the gold standard for diagnosing gastroparesis. Concerning therapy used, three-third of the cases received glucocorticoids 1 mg/kg daily. In two-third of the cases, azathioprine was used. Before starting the corticosteroids therapy, all the cases received antibiotics and motility stimulants with poor outcomes. The early diagnosis of gastroparesis with SLE must be rapid so that the therapy can be initiated promptly. Due to the severity of the condition that may result in nausea, abdominal pains, and satiety, using endoscopy and gastric emptying scintigraphy is fundamental.

Metabolic and nutritional triggers associated with increased risk of liver complications in SARS-CoV-2.

Obesity, diabetes, cardiovascular and respiratory diseases, cancer and smoking are risk factors for negative outcomes in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which can quickly induce severe respiratory failure in 5% of cases. Coronavirus disease-associated liver injury may occur during progression of SARS-CoV-2 in patients with or without pre-existing liver disease, and damage to the liver parenchyma can be caused by infection of hepatocytes. Cirrhosis patients may be particularly vulnerable to SARS-CoV-2 if suffering with cirrhosis-associated immune dysfunction. Furthermore, pharmacotherapies including macrolide or quinolone antibiotics and steroids can also induce liver damage. In this review we addressed nutritional status and nutritional interventions in severe SARS-CoV-2 liver patients. As guidelines for SARS-CoV-2 in intensive care (IC) specifically are not yet available, strategies for management of sepsis and SARS are suggested in SARS-CoV-2. Early enteral nutrition (EN) should be started soon after IC admission, preferably employing iso-osmolar polymeric formula with initial protein content at 0.8 g/kg per day progressively increasing up to 1.3 g/kg per day and enriched with fish oil at 0.1 g/kg per day to 0.2 g/kg per day. Monitoring is necessary to identify signs of intolerance, hemodynamic instability and metabolic disorders, and transition to parenteral nutrition should not be delayed when energy and protein targets cannot be met via EN. Nutrients including vitamins A, C, D, E, B6, B12, folic acid, zinc, selenium and ω-3 fatty acids have in isolation or in combination shown beneficial effects upon immune function and inflammation modulation. Cautious and monitored supplementation up to upper limits may be beneficial in management strategies for SARS-CoV-2 liver patients.

Primary Antiphospholipid Syndrome with and Without Acute Myocardial Infarction/Angina: A Cross-Sectional Study.

INTRODUCTION: Acute myocardial infarct/angina (AMI-A) is a possible complication in primary antiphospholipid syndrome (pAPS) patients. This study compares data obtained from pAPS patients with and without AMI-A. METHODS: This cross-sectional study of 66 (85.2% female) pAPS patients (Sidney criteria). Demographics, clinical data, medication use, and antiphospholipid antibodies were evaluated. Patients were divided into two groups: pAPS with AMI-A and pAPS without AMI-A. RESULTS: Sixty-six patients with primary APS (six with AMI-A and 60 without AMI-A) were selected. They were similar for demographics, disease duration, and anthropometrics (p > 0.05). Patients with AMI-A compared to those patients without AMI-A had more frequently dyslipidemia (66 vs. 28%, p = 0.05), systemic hypertension (83 vs. 37%, p = 0.02), and increased levels of lipoprotein (a) (116 ± 67 vs. 36 ± 35 mg/dl, p = 0.0002). Interesting, current physical activity (66.7 vs. 23%, p = 0.04) was more seen in the first group when compared to the second one. Patients with AMI-A used more statins (66 vs. 22%, p = 0.017) and acetylsalicylic (100 vs. 28%, p = 0.05). Higher median levels of IgM anticardiolipin antibodies [70 (0-120) vs. 9 (0-120), p = 0.03] were observed in the first group. CONCLUSIONS: pAPS patients and AMI-A have distinct clinical and laboratory spectra from those without AMI-A. It is characterized by dyslipidemia and hypertension, hyper lipoprotein(a), and a lower IgM anticardiolipin frequency.
