Skin reaction to capsaicin in patients with systemic lupus erythematosus compared to healthy controls.

Caspian J Intern Med 2021 Mar;12(2):140-147

Rheumatic Diseases Research Center, Mashhad University of Medical Sciences, Mashhad, Iran.

Background: The interaction between nervous and immune systems has been under investigation. Transient receptor potential vanilloid type 1(TRPV1) is a ligand gated calcium channel expressed by sensory neurons which mediates neurogenic inflammatory response. Substance p which can be released following exposure to capsaicin is a TRPV1 inducer, shown to have altered concentration and function in mice with systemic lupus erythematosus (SLE). We evaluated skin reaction to capsaicin in newly diagnosed and established SLE patients compared to healthy controls.

Methods: Twenty-nine SLE patients (12 newly diagnosed cases under treatment, and 17 established ones, not receiving medications) who referred to rheumatologic disease research center, and 33 healthy subjects of the control group were recruited in this study. A topical solution of capsaicin (0.075%) was applied on the volar forearm during skin test, and time to the tingling sensation, area of induration and area of redness (centimeters) were recorded after 5, 10, and 20 minutes.

Results: The area of redness and area of induration within 15 minutes, time to the tingling sensation (P=0.02), and the overall frequency of tingling sensation (P=0.01) after capsaicin skin test was considerably higher in SLE patients than the healthy controls. Redness, induration and tingling sensation were more frequent but not statistically significant among the established SLE group compared to the newly diagnosed patients.

Conclusion: Since skin reaction to capsaicin is more prominent in SLE patients than the healthy individuals, neurogenic inflammation and the role of P substance should be investigated more in ongoing lupus. Capsaicin test can not predict lupus activity.

Evaluation of iron, ferritin, copper, and ceruloplasmin along with proviral load in human T lymphotropic virus type 1-associated myelopathy.

J Neurovirol 2021 Apr 20. Epub 2021 Apr 20.

Department of Neurology, Faculty of Medicine, Qaem Hospital, Mashhad University of Medical Sciences, Ahmadabad Avenue, 91766-99199, Mashhad, Iran.

Human T-cell lymphotropic virus type 1 (HTLV-1) infection can cause HTLV-I-associated myelopathy (HAM). In this study, we evaluated the levels of serum iron, ferritin, copper, and ceruloplasmin, and their correlations with HTLV-1 proviral load (PVL) and standard indices of HAM severity. In total, 114 subjects were recruited in this cross sectional study in Qaem Hospital, Mashhad, Iran between 2017 and 2018, including 36 HAM and 32 asymptomatic cases (ACs) and 46 healthy people (HSs). The clinical examination and evaluation of serum levels of biochemical factors and proviral load were performed. The PVL in HAM and ACs were 1835.49 ± 382.81 and 280.97 ± 67.41 copies/10 PBMCs, which statistically differed. Significant differences were also observed in plasma levels of iron, copper, and ceruloplasmin, among the three groups, while ferritin level was not considerably different. For HAM severity, the mean Osame motor disability scale (OMDS) and overactive bladder-validated-8-questionnaire (OABV-8) scores were 4.97 ± 0.38 and 15.75 ± 0.83, respectively, that had no significant correlations with the biochemical variables. Even though the studied elements in HAM group did not affect the severity of the disease, the levels of copper and ceruloplasmin might be determinants of the development and progression of HAM, as they are shown to play role in progression of other neurological diseases.

A follow-up study on Guillain-Barre syndrome and validation of Brighton criteria.

Iran J Neurol 2019 Apr;18(2):64-69

Inflammation and Inflammatory Disease Research Center, Mashhad University of Medical Sciences, Mashhad, Iran.

Guillain-Barre syndrome (GBS) is the major cause of acute flaccid paralysis (AFP). Comprehensive classification and predictive measures need to be created for GBS. This study was conducted to evaluate GBS patients' prognosis and Brighton criteria validity in Iranian population. This retrospective cohort study was conducted using medical records of patients with GBS admitted to Ghaem Hospital, Mashhad, Iran. After collecting data from cerebrospinal fluid (CSF) analysis, nerve conduction studies, and clinical examinations, Brighton criteria and GBS disability scores were calculated. Patients ultimately received follow-up telephone calls after 15 to 45 months of admission, checking on one's clinical status and the ability to walk independently. Data were analyzed using SPSS software. Patients were mostly men (78.0%) with the mean age of 48.58 years. GBS onset was reported more frequently in spring. According to Brighton criteria, 41.4%, 51.6%, and 7.0% of the patients were classified as levels 1, 2, and 4, respectively. For GBS disability score, 54.7%, 16.4%, 9.4%, and 6.2% of the patients had grades of 4, 3, 2, and 1, respectively. 37 patients (39.4%) restored the ability to walk within the first month, while 3 patients (3.2%) were unable to walk by the end of the second year. Significant relationship was observed between the ability of walking independently and GBS disability score (P < 0.001). In the Iranian GBS population, less than half of the patients met level 1 of Brighton criteria and more than half of them reached the GBS disability score of 4, and walking ability was correlated to GBS disability score.

Metabolic syndrome in lupus patients in northeast of Iran, and their lifestyle habits.

Caspian J Intern Med 2016 ;7(3):195-200

Rheumatic Diseases Research Center, School of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran.

Background: Systemic lupus erythematous is an autoimmune disease associated with atherosclerotic manifestations or metabolic disturbance due to inflammation. The aim of this study was to determine frequency of metabolic syndrome (MetS) in SLE compared to healthy controls.

Methods: In this cross-sectional study, 150 SLE patients and 220 healthy volunteers were enrolled. MetS was diagnosed according to ATPIII criteria. Patients and controls were compared according to prevalence of MetS. In addition, SLE patients with and without MetS were compared according to laboratory parameters. Each patient also fulfilled a checklist about routine daily activities and diet program. Data were analyzed by SPSS-11 software.

Results: MetS was significantly lower in SLE than healthy controls (18% vs 29.1%, P=0.015). Disease manifestations, major organ involvement, serum values of complements and anti-DNA antibody and pharmacological therapy did not correlate with MetS occurrence in patients. The mean TG, FBS, systolic and diastolic BP were statistically higher in lupus patients compared to healthy volunteers in contrast to waist circumference. HDL-cholesterol serum values did not show any significant difference between two groups.

Conclusion: It seems that despite higher values of blood pressure, serum lipids and glucose in lupus patients, the cumulative metabolic components were in a manner to make MetS more prevalent in healthy volunteers. As far as life habits are concerned, lupus patients in general did not exercise enough and did not go on a healthy diet despite of glucocorticoid therapy and hypertension.
