    Rheumatoid arthritis (RA) is a progressive inflammatory disorder characterized by swollen joints, discomfort, tightness, bone degeneration and frailty. Genetic, agamogenetic and sex-specific variables, Prevotella, diet, oral health and gut microbiota imbalance are all likely causes of the onset or development of RA, perhaps the specific pathways remain unknown. Lactobacillus spp. probiotics are often utilized as relief or dietary supplements to treat bowel diseases, build a strong immune system and sustain the immune system. At present, the action mechanism of Lactobacillus spp. towards RA remains unknown. Therefore, researchers conclude the latest analysis to effectively comprehend the ultimate pathogenicity of rheumatoid arthritis, as well as the functions of probiotics, specifically Lactobacillus casei or Lactobacillus acidophilus, in the treatment of RA in therapeutic and diagnostic reports. RA is a chronic inflammation immunological illness wherein the gut microbiota is affected. Probiotics are organisms that can regulate gut microbiota, which may assist to relieve RA manifestations. Over the last two decades, there has been a surge in the use of probiotics. However, just a few research have considered the effect of probiotic administration on the treatment and prevention of arthritis. Randomized regulated experimental trials have shown that particular probiotics supplement has anti-inflammatory benefits, helps people with RA enhance daily activities and alleviates symptoms. As a result, utilizing probiotic microorganisms as therapeutics could be a potential possibility for arthritis treatment. This review highlights the known data on the therapeutic and preventative effects of probiotics in RA, as well as their interactions.

    Chandirasekar R, Kumar BL, Jayakumar R, Uthayakumar V, Jacob R, Sasikala K
    Clin Chim Acta, 2015 Jan 15;439:77-83.
    PMID: 25307208 DOI: 10.1016/j.cca.2014.10.005
    BACKGROUND: Rheumatoid arthritis is the commonest inflammatory joint disease, affecting nearly 1% of the adult population worldwide. Early and accurate diagnosis and prognosis of rheumatoid arthritis (RA) have become increasingly important. In the present study, we aimed to elucidate the relationships between hematological, biochemical, immunological and cytogenetic parameters in rheumatoid arthritis patients and healthy normal controls.
    METHODS:The study group comprised of 126 RA patients and equal number of healthy normal control subjects. The blood wa s collected and analyzed for biochemical, immunological, enzymatic and cytogenetic parameters.
    RESULTS: Results of the present study indicated that 20% of RA patient's hematological, 31% of biochemical and 70% immunological parameters had a significant difference from the controls and reference range. The RF and anti-CCP antibody levels were also positive in 70% of RA patients. A significant increase in minor chromosomal abnormalities was also observed in patients as compared to controls.
    CONCLUSION: The knowledge about autoimmune diseases is very low among the South Indian population. The present study has thus helped in understanding the RA disease in a better way based on a pattern of various clinical markers of the disease condition which might help in planning therapeutic intervention strategies and create awareness about the disease management among RA patients of the population studied.

  4. Fulltext Predictors of frequent oral analgesic use in rheumatoid arthritis
    Das Gupta E, Tee HS, Sakthiswary R
    Pak J Med Sci, 2014 Sep;30(5):976-81.
    PMID: 25225510 DOI: 10.12669/pjms.305.5112
    Objective: The main objective of this study was to determine the predictors of frequent oral analgesic use among Rheumatoid Arthritis (RA) patients who were prescribed with the above medication on an ‘as needed’ basis.
    Methods: Patients with RA were recruited consecutively from the Rheumatology outpatient clinics in this cross-sectional study. The sociodemographic data, frequency of oral analgesic intake, Patient Global Assessment (PGA) scores and HAQ (Health Assessment Questionnaire) scores were determined by interviewing the subjects. Subjects were divided into 2 groups; frequent users (3 days and above in a week) and less frequent users (less than 3 days in a week).
    Results: In a total of 112 subjects, 39 (34.8%) were frequent analgesic users. Both the HAQ and PGA scores were significantly higher among the frequent users (p < 0.05). Using multivariate analysis, the HAQ scores (p=0.015, odds ratio 3.161 [95% confidence interval of 1.246-8.015]) and PGA scores (p=0.039 odds ratio 1.291 [95% confidence interval of 1.012-1.646]) were found to be independent predictors of frequent analgesic use.
    Conclusions: Our study confirms that the frequency of analgesic intake in Rheumatoid Arthritis has a significant relationship with patient-reported functional capacity and well being.

  5. Potential mechanisms linking periodontitis to rheumatoid arthritis
    Lee YH, Lew PH, Cheah CW, Rahman MT, Baharuddin NA, Vaithilingam RD
    J Int Acad Periodontol, 2019 07 01;21(3):99-110.
    PMID: 31473702
    Periodontitis (PD), a chronic inflammatory disease which results in irreversible attachment loss, bone destruction and tooth loss, is a major oral health problem. Rheumatoid arthritis (RA), with a global prevalence of 1%, is an autoimmune disease characterized as a chronic inflammatory disorder leading to synovial inflammation and destruction of cartilage and bone. Studies have reported an association between PD and RA whereby PD is reportedly more severe in patients with established RA. Justification for the plausible link between both conditions is based on shared characteristics and pathogenic similarities with regard to risk factors, immunogenetics and tissue destruction pathways. The search for the possible mechanism linking PD to RA continues as it can play an important role in enabling early intervention in the form of prevention and treatment of infection. This will ultimately improve patients' oral health related quality of life and reduce societal burden related to increased patient discomfort and treatment costs. The current review provides an update on the cellular and molecular events that have thus far explained the link.

    Rheumatoid arthritis (RA) is a chronic inflammatory condition that can be associated with abnormal bone turnover and hence osteoporosis. Osteocalcin (OC) levels are increased in conditions with high bone turnover, including high RA disease activity. Thus, OC levels could possibly be used as a marker to assess bone health and disease activity in RA patients. As there have been no previous studies looking at serum OC levels in Malaysian RA patients, this study was performed to examine possible correlations between OC, bone mineral density (BMD) and disease activity in this population. A cross-sectional study of 75 female RA patients and 29 healthy controls was performed. Serum OC was measured using a Quantikine® ELISA kit. Dualenergy x-ray absorptiometry (DXA) was used to assess BMD. Serum OC levels were not significantly different between RA patients (median 14.44 ng/mL, interquartile range [IQR 12.99]) compared to healthy controls (median 11.04 ng/mL IQR 12.29) (p=0.198). Serum OC increased with age (Spearman’s rho r=0.230, p=0.047). There was no significant correlation between serum OC and body mass index (BMI), menopause status, BMD, DAS28, swollen or tender joint counts. Overall, there were 11 (14.7%) patients with osteoporosis and 27 (36.0%) with osteopenia. Menopause status was significantly associated with BMD at all sites (lumbar spine p=0.002, femoral neck p=0.004, total hip p=0.002). Serum OC were similar in RA patients compared to healthy controls. In RA patients, serum OC did not correlate with RA disease activity or BMD. Menopause status remains an important influence on BMD. Thus, measuring serum OC levels in Malaysian RA patients was not useful in identifying those at risk of low BMD.

  7. Fulltext Septic hip dislocation with a preserved femoral head: successful outcome following open reduction
    Kamal J, Abdul Halim AR, Sharaf I
    Medicine & Health, 2017;12(2):335-340.
    MyJurnal
    Septic arthritis of the hip in children represents a serious disorder with unfavourable long-term sequelae. In neonates, a poor hip outcome is expected especially if the treatment was delayed. Late sequelae can lead to structural joint damage and instability, causing deformity and dislocations which ultimately may result in limb length discrepancy, early degenerative changes and limited range of motion. Surgery at the appropriate time can improve the hip condition and functional outcome. Previous classifications of post septic hip sequelae are useful guides for treatment, but did not discuss one particular group of patient. This group-septic hip dislocation with a preserved femoral head, has recently been described as a distinct entity. This report highlights an 11-year follow-up of a 2-year-old child who had a successful outcome following open reduction and varus derotation
    osteotomy for a septic hip dislocation with a preserved femoral head.

  8. Bacterial quality of urinary tract in patients with alkaptonuria
    Al-Tarawneh A, Al-Limoun M, Khlaifat AM, Tarawneh I, Mwafi N, Khleifat K, et al.
    Am J Med Sci, 2023 Apr;365(4):368-374.
    PMID: 36608845 DOI: 10.1016/j.amjms.2022.12.028
    BACKGROUND: The aim of the current study was to determine whether there is an association between alkaptonuria (AKU) and urinary tract infection (UTI) by exploring the bacterial quality of the urinary tract, as most of the patients with AKU present with frequent occurrence of urinary tract symptoms such as incomplete emptying of urinary bladder, dysuria and nocturia.

    METHODS: Study samples were collected from 22 participants; 9 from patients with AKU, 9 from individuals who were AKU carriers, and 4 people served as control. Confirmation of AKU diagnosis was established by the ferric chloride test and quantitative determination of urinary homogentisic acid (HGA) levels.

    RESULTS: In the ferric chloride test, the urine samples of AKU patients showed a characteristic black ring upon addition of few drops of ferric chloride solution. During urinary HGA determination, patients with AKU had increased levels of urinary HGA as compared to carriers and controls. The following 10 bacterial species were isolated from the urinary tract of AKU patients, carriers and controls: Sphingomonas paucimobilis, Escherichia coli, Francisella tularensis, Staphylococcus hominis, Staphylococcus haemolyticus, Leuconostoc mesenteroides, Dermacoccus nishinomiyaensis, Kytococcus sedentarius, Serratia fonticola and Granulicatella adiacens. The presence of S. paucimobilis was found in three male patients, and one female each from the carrier and control groups. Almost all study samples were positive for D. nishinomiyaensis and K. sedentarius. S. fonticola and G. adiacens were found only in AKU carrier females.

    CONCLUSIONS: The results deduced that males show symptoms of arthritis early and more severely than females and by this it appears that there is an association between these symptoms and the percentage of bacterial infection in males that requires more accurate diagnosis and treatment to clarify such relationship. In the current study, males (patients, carriers, and controls) were more likely to have bacterial infections than females (64% vs. 36%). The 16 and 2 bacterial isolates, detected in 7 males and 2 females AKU patients, respectively, revealed that male AKU patients had a 2.3-fold greater rate of bacterial infection than female AKU patients. Therefore, further studies are warranted to investigate if there's any relationship between higher incidence of bacterial infections and development of AKU-related clinical symptoms in the male population.

  9. Fulltext Interleukin-23 and its correlation with disease activity, joint damage, and functional disability in rheumatoid arthritis
    Dalila AS, Mohd Said MS, Shaharir SS, Asrul AW, Low SF, Shamsul AS, et al.
    Kaohsiung J. Med. Sci., 2014 Jul;30(7):337-42.
    PMID: 24924839 DOI: 10.1016/j.kjms.2014.02.010
    The purpose of this study was to compare the serum interleukin (IL)-23 levels between rheumatoid arthritis (RA) patients and healthy controls and to determine the correlation of IL-23 levels with disease activity, joint damage and functional disability in RA. Serum samples were obtained from 45 patients with RA and 45 healthy controls. The enzyme-linked immunosorbent assay method was used for quantitative analysis of IL-23. All the RA patients were assessed for disease activity based on the 28-joint disease activity score, joint damage based on modified Sharp score, and functional ability using the Health Assessment Questionnaire-Disability Index. The mean serum IL-23 level was much higher among the RA patients (24.50 ± 13.98 pg/mL) compared to the controls (5.98 ± 3.40 pg/mL; p < 0.01). There was a significant positive relationship between IL-23 levels and disease activity and questionnaire scores (p = 0.003 and 0.020, respectively). On logistic regression analysis, IL-23 levels were significantly higher in patients with moderate to high disease activity (p = 0.008, odds ratio = 1.073, 95% confidence interval = 1.019-1.130) and patients with significant functional disability (p = 0.008, odds ratio = 1.085, 95% confidence interval = 1.021-1.153). RA patients have significantly higher levels of serum IL-23. The IL-23 levels correlate well with disease activity and functional disability but not with radiographic joint damage.

    Total talus dislocation is a rare injury and is commonly accompanied by associated fractures. Common worrisome sequelae are infection, avascular necrosis and post-traumatic arthritis. We report here on a patient who sustained an open total talus dislocation with an ipsilateral medial malleolus fracture. Following early debridement, reduction and a combination of internal and external fixations, early recovery was good with no evidence of avascular necrosis.

  14. The association between HLA genes and radiological erosions in Malaysian patients with rheumatoid arthritis
    Yeap SS, Mohd A, Kumar G, Kong KF, Chow SK, Goh EM, et al.
    Autoimmunity, 2007 May;40(3):187-90.
    PMID: 17453717 DOI: 10.1080/08916930701233755
    OBJECTIVE:
    To assess the relationship between the HLA-DRB1 genes with disease severity as assessed by radiological erosions in Malaysian patients with rheumatoid arthritis (RA).

    METHODS:
    In this cross-sectional study, we studied 61 RA patients who fulfilled the ACR criteria for the diagnosis of RA. HLA-DRB1 genotyping was performed by sequence specific primer (SSP) - PCR. Radiological grading and erosive score of the hands and wrists was calculated according to the Larsen-Dale method. Demographic data and treatment given to the patients were obtained from their case records.

    RESULTS:
    Fifty-six females and five males were studied from three ethnic groups. In 57 patients with erosions, rheumatoid factor was detected in 80%, HLA-DR4 in 40%, HLA-DRB1*0405 in 24% and shared epitope (SE) in 31%. The median delay in starting DMARDs was 24 months. The presence of rheumatoid factor, HLA-DR4 and HLA-DRB1*0405 were not significantly associated with a worse erosive score. Patients who possessed the SE had a higher erosive scores, compared to those who did not (p = 0.05). Concurrently, a delay in starting DMARD was associated with a high erosive score (p = 0.023, r = 0.348). However, after adjustment for the delay in starting DMARD, SE was no longer significantly associated with the erosive score.

    CONCLUSIONS:
    In these patients, the delay in starting DMARDs had a greater influence on the erosive score than SE alone. Whilst we cannot discount the contribution of the SE presence, we would advocate early usage of DMARDs in every RA patient to reduce joint erosions and future disability.

    Objective. To compare ultrasound synovial thickness of the 2nd, 3rd and 4th metacarpophalangeal joints (MCPJ) in a group of patients with proven rheumatoid arthritis (RA) and a control group of normal individuals. Materials and Methods. This is a cross-sectional study comprising 30 rheumatoid arthritis patients and 30 healthy individuals. Ultrasound scans were performed at the dorsal side of 2nd, 3rd, and 4th MCPJ of both hands in RA patients and the healthy individuals. Synovial thickness was measured according to quantitative method. The synovial thickness of RA patients and healthy individuals was compared and statistical cut-off was identified. Results. Maximum synovial thickness was most often detected at the radial side of the 2nd MCPJ and 3rd MCPJ and ulnar side of the 4th MCPJ of both hands which is significantly higher (p < 0.05) in RA patients compared to healthy individuals. With high specificity (96%) and sensitivity (90%) the optimum cut-off value to distinguish RA patients and healthy individuals' synovial thickness differs for the radial side of the 2nd and 3rd MCPJ and ulnar side of the 4th MCPJ. Conclusion. Patients with early RA appear to exhibit a characteristic pattern of synovitis which shows radial side predominance in the 2nd and 3rd MCPJ and ulnar side in the 4th MCPJ.

    Razak M, Nasiruddin J
    Med J Malaysia, 1998 Sep;53 Suppl A:86-94.
    PMID: 10968188
    Forty-one patients with 42 joint infections were admitted to the hospital between June 1989 and June 1994. An overview on the behaviour of septic arthritis in both children and adults, at presentation and after various types of treatment was done. There were 32 knees, 7 hips, 2 elbows and 1 shoulder. Duration of symptoms, type of organism, type of joint drainage, presence of preexisting joint problems and presence of osteomyelitis are among the important factors with prognostic significance. Seventy three percent of patients with less than 7 days duration of symptoms had satisfactory results. Whereas when the duration of symptoms exceeded 7 days, 75% of the patients had unsatisfactory outcome. All cases with poor outcome had positive cultures. Staphylococcus aureus was responsible for 77% of the culture-positive cases. All Staphylococcus aureus in this study were penicillin-resistant but sensitive to cloxacillin. There were 3 instances where Staphylococcus became resistant to cloxacillin following recurrence of septic arthritis. However, they were still sensitive to third generation cephalosporin. Staphylococcus aureus was capable of producing poor results even when the case was treated early. Other organisms were gram-negative bacilli which infect patients with suppressed immune system, that is, intravenous drug abuser, systemic steroid therapy and diabetes mellitus. Open arthrotomy was the method of drainage used in all hip sepsis. This method was also the most reliable method of joint drainage in other joints compared to aspiration method when frank pus was already present. Most immuno-compromised patients recovered badly from septic arthritis. Associated adjacent osteomyelitis, preexisting chronic arthritis and recent intra-articular fractures were also noted to adversely affect the functional outcome.

    PMID: 3265604
    410 cases of psoriasis [282 males (68%) and 127 females (31%)] were interviewed and examined to study the nail changes. The prevalence of nail changes was 78.0% (males = females). Common changes were pitting (67.5%) and onycholysis (67.2%). Dystrophy of varying degrees occurred in 35.0%, subungual hyperkeratosis in 24.7%, discoloration in 18.4%, loss of nails in 2.8% and pustulation in 1.3%. Pitting and onycholysis was the most common combination (45.6%). Nail changes were significantly more common in patients who have moderate to severe psoriasis as compared with patients with mild psoriasis; in patients who have psoriasis for greater than 5 years as compared with patients who have psoriasis for less than 5 years; and in patients older than age 50 as compared with those aged less than 50. A definite correlation was found between the prevalence of nail changes and the presence of scalp and periungual psoriasis, and the presence of joint involvement.

  19. Involvement of the kinin-forming system in the physiopathology of rheumatoid inflammation
    Sharma JN
    Agents Actions Suppl., 1992;38 ( Pt 3):343-61.
    PMID: 1334358
    Kinins are potent mediators of rheumatoid inflammation. The components of the kinin-forming system are hyperactive in RA. Excessive release of kinins in the synovial fluid can produce oedema, pain and loss of functions due to activation of B1 and B2 receptors. These receptors could be stimulated via injury, trauma, coagulation pathways (Hageman factor and thrombin) and immune complexes. The activated B1 and B2 receptors might cause release of other powerful non-cytokines and cytokines mediators of inflammation, for example, PGE2, PGI2, LTs, histamine, PAF, IL-1 and TNF derived mainly from polymorphonuclear leukocytes, macrophages, endothelial cells and synovial tissue. These mediators are capable of inducing bone and cartilage damage, hypertrophic synovitis, vessels proliferation, inflammatory cells migration, and possibly angiogenesis in pannus formation. These pathological changes, however, are not yet defined in human model of chronic inflammation (RA). Hence, the role of kinin and its interacting inflammatory mediators would soon start to clarify the detailed questions they revealed in clinical and experimental models of chronic inflammatory joint diseases. Several B1 and B2 receptor antagonists are being synthesized in an attempt to study the molecular functions of kinins in inflammatory processes (RA, periodontitis and osteomyelitis), and they represent and important area for continued research in rheumatology. Future development of specific, potent and stable B1 and B2 receptor antagonists or combined B1 and B2 antagonists with y-IFN might serve as pharmacological basis of more effective rationally-based therapies for RA. This may lead to significant advances in our knowledge of the mechanisms and therapeutics of rheumatic diseases.

    DOI: 10.1111/j.1756-185X.2008.00384.x
    Objective: To validate the Malay version of the Health Assessment Questionnaire (Malay-HAQ) for use in Malay-speaking rheumatoid arthritis (RA) patients in the Malaysian setting. The HAQ - Disability Index has been validated in several languages, but not in Malay.Methods: The original HAQ was modified and translated into Malay by two translators, one of whom was aware of the objectives of the Questionnaire and the other as a lay translator. Two sets of Malay-HAQ were distributed to RA patients during their routine follow-up visits; one set to be completed immediately and another set to be completed 2 weeks later. A total of 61 patients completed the two sets of Malay-HAQ. The data collected was analysed using SPSS V. 11.0. Reliability of the data was evaluated using the test-retest method and internal consistency was assessed by Cronbach's alpha.Results: The study showed that the Malay-HAQ is feasible and reliable. The Spearman's correlation coefficient ranged from 0.65 to 0.82, while the internal consistency was 0.88-0.92.Conclusion: The Malay-HAQ is a sensitive, reliable and valid instrument for the measurement of functional status in RA patients in a Malay setting. © 2008 Asia Pacific League of Associations for Rheumatology.
