The sodium does not affect joint pain and functional activity of knee osteoarthritis patients.

Background: The sodium may aggravate synovial inflammation and cartilage thinning. This incidence can cause joint pain and reduce functional activity. Not many people know the effect of sodium on the incidence of osteoarthritis. Objective: This study aims to determine the relationship between sodium in the body and knee joint pain which results in functional activity. Methods: The quantitative descriptive study used accidental sampling. The study was conducted at three outpatient polyclinic orthopedics of hospitals and was approved by the Health Ethics Committee. All data were collected during the interview. The Semi-Quantitative Food Frequency Questionnaire and the Nutrisurvey Indonesia 2007 application were used as a tool to collect daily sodium intake (mg). Knee joint pain score was measured using the Visual Analog Scale (VAS), while functional body activity was measured using the Western Ontario McMaster Osteoarthritis Index (WOMAC). The Pearson and Spearman test (P<0.05) were used as a correlation test. Results: 80 subjects were recruited according to the inclusion criteria. Characteristics of the subjects were pre-elderly (32, 40%), women (74, 92.5%), body mass index ≥30 kg/m2 (54, 67.5%) and occupation (43, 53.75%). Average sodium intake = 2090.78±1084.33 mg, VAS score = 6.28±1.95 and WOMAC score = 32.65±14.88. The correlation sodium, VAS, and WOMAC were not significant (P=0.196, P=0.372). Conclusions: Increased sodium intake is not associated with knee joint pain and functional body activity.

The roles of Single Nucleotide Polymorphism (SNP) Endoplasmic Reticulum Aminopeptidase 1 (ERAP 1) gene in axial spondyloarthritis Indonesian adults.

Background: Axial Spondyloarthritis (AxSpA) is chronic inflammatory arthritis involving the axial joint whose pathogenesis is related to the SNP ERAP1 gene, HLA B27, and cytokine proinflammatory (IL-17A and IL-23). Objective: Analyzed the role of SNP gene ERAP1 on disease activity and proinflammatory cytokines. Methods: This study comprised of two phases including a cross-sectional study and an in-vitro experiment in post-test with a control-group design. Participants underwent a PCR investigation searching for HLA-B27. Disease activities were measured by Ankylosing Spondylitis Disease Activity Score-Erythrocyte Sedimentation Rate (ASDAS-ESR) and modified Stokes Ankylosing Spondylitis Spinal Score (mSASSS). Subjects with HLA-B27 positive underwent PCR ERAP1 gene rs27434, genome-sequencing, and analysis. ELISA sandwich method was used to measure ERAP-1, IL-17, and IL-23 levels with lipopolysaccharide and IFN-γ induction. Analysis using independent t-test, Mann Whitney, and Pearson correlation test with p < 0.05. Results: The average ASDAS-ESR was 3.33 ± 0.89 and the average mSASSS was 26.53 ± 9.90. In HLA B27 positive group, SNP ERAP1 gene rs 27434 in which alleles A changed to G and A/G with genotypes AA to AG/GG was observed. SNPs of the ERAP1 gene had a correlation on mSASSS (r = 0.553; p < 0.05) and no correlation on ASDAS-ESR (r = 0.232; p = 0.235). There were significant differences observed in the SNP ERAP1 gene on ERAP1 and IL-17A levels in subjects with lipopolysaccharide and IFN-γ induction (p = 0.05) but no significant difference in IL-23 levels (p > 0.05). Conclusion: The SNP ERAP1 gene affects mSASSS value, ERAP1 levels, and IL-17A levels whereas ASDAS-ESR value and IL-23 level were not associated.

Association of Polymorphisms in C-Reactive Protein (CRP) Promoter -821 A>G, -390 C>A/T, and Plasma Interferon-α (IFN-α) with Plasma CRP Level in Javanese Systemic Lupus Erythematosus (SLE) Patients.

BACKGROUND: As an acute-phase reactant, CRP is needed to clear apoptotic cells and immune complexes in SLE. This unresponsive CRP may be caused by genetic variation and abundant IFN-α that might inhibit CRP secretion. This study aims to analyze the association of single nucleotide polymorphisms (SNP) in CRP promoter and plasma IFN-α with CRP level in Javanese SLE patients. We also analyzed the association of these SNPs with SLE. METHODS: Forty SLE and 40 spondyloarthritis (as control) patients were included. SLE subjects underwent routine laboratory test, CRP level, serum IFN-α, and DNA sequencing to detect SNPs in CRP promoter. The control group only underwent DNA sequencing. RESULTS: The median age of SLE patients was 31.5 years. The median SLAM score was 8.5. The median age of the control group was 39 years. The average CRP was 5.19 SD 2.69 mg/L, median plasma IFN-α was 46.02 pg/ml. There was no significant difference of SNPs in CRP -821 (rs2794521) or -390 (rs3091244) between SLE and control. New SNP was found in CRP -456 A>G in 5 SLE patients, but none in controls. This SNP would increase SLE risk 2.143 times. There was a moderate negative correlation between IFN-α level and plasma CRP. Linear regression only showed IFN-α level (not either SNP) correlated with serum CRP. CONCLUSION: Plasma IFN-α correlated with CRP level. There was no association of SNPs in CRP -821, -390, and -456 with CRP level. SNP CRP -456 A>G would increase the risk of SLE with an odds ratio of 2.143.

Effects of Hyperbaric Oxygen on T helper 17/regulatory T Polarization in Antigen and Collagen-induced Arthritis: Hypoxia-inducible Factor-1α as a Target.

OBJECTIVES: We sought to investigate and prove the effect of hyperbaric oxygen therapy (HBOT) on T helper 17 (Th17)/regulatory T (Treg) cell polarization through changes in the expression of hypoxia-inducible factor-1 alpha (HIF-1α) in rheumatoid arthritis (RA) animal model. METHODS: We used antigen and collagen-induced arthritis (ACIA) as a RA animal model. Sixteen male BALB/c models of ACIA mice were divided into two groups, the non-HBOT group as the control group and the HBOT group as the treatment group. Expression of HIF-1α, Th17 anti-cluster differentiation 196 (CD196), and Treg anti-interleukine 2 receptor ß-chain cells (IL-2Rß) in tissue from the left knee joint tissue were determined histologically. Oxidative stress and systemic inflammation were assessed by levels of superoxide dismutase (SOD), interleukin 17a (IL-17a), C-reactive protein (CRP), and rheumatoid factor (RF) using the enzyme-linked immune-sorbent assay. The degree of arthritis was assessed by clinical scoring of paw swelling and the diameter of paw swelling. RESULTS: We found a significant decrease (p < 0.050) in the expression of HIF-1α, Th17 (CD196), IL-17a, RF levels, and the clinical scores and the diameter of paw swelling when comparing both groups. There was no significant decrease in the level of CRP in the treatment group compared to the control group. The expression of Treg (IL-2Rß) increased significantly (p < 0.050) and the level of SOD increased but not significantly (p > 0.050) in the treatment group compared to the control group. CONCLUSIONS: HBOT has effects on the polarization of Th17 to Treg through a decrease in expression of HIF-1α in mice with ACIA. HBOT is recommended for use as a support therapy for RA in combination with drug therapy.

The Role of Serum Expression Levels of Microrna-21 on Bone Mineral Density in Hypostrogenic Postmenopausal Women with Osteoporosis: Study on Level of RANKL, OPG, TGFß-1, Sclerostin, RANKL/OPG Ratio, and Physical Activity.

BACKGROUND: MiR-21 is known to play a role in osteoclast proliferation and differentiation, but the role of serum miR-21 expression in osteoporosis remains unclear. Previous research found that serum miR-21 expression was positively correlated with bone mineral density in postmenopausal osteoporosis patients, but other factors involved in postmenopausal osteoporosis still unknown. This study aimed to determine the role of serum miR-21 expression, concentration of RANKL, OPG, TGF-ß1, sclerostin and serum calcium, RANKL/OPG ratio, and physical activity on bone mineral density of spine in hypoestrogenic postmenopausal women with osteoporosis (PMOP) compared with no osteoporosis (PMNOP), with point of interest on the expression of serum miR-21. METHODS: this study was conducted by comparative cross-sectional design. The subjects were divided into 2 groups of PMOP and PMNOP. We used an absolute quantification real-time PCR method to determine serum miR-21 expressions level. RESULTS: Median of serum miR-21 expression at the PMOP group was significantly higher compared to PMNOP group (p = 0.001). Serum miR-21 expression, RANKL, RANKL/OPG ratio, and physical activity were significantly correlated with BMD values in the PMOP group. Moderate physical activity was significantly negatively correlated with serum miR-21 expression. We also obtained a linear regression equation BMD = 1.373-0.085*Ln.miR-21-0.176*Log10.RANKL (R2 = 52.5%). CONCLUSION: serum miR-21 expression in PMOP was higher compared with PMNOP. Serum miR-21 expression proved to have a negative effect on spinal BMD values in hypoestrogenic postmenopausal women with osteoporosis of 8.5%. Obtained equation of BMD = 1.373-0.085*Ln.miR-21-0.176*Log10.RANKL can explain the value of spinal BMD by 52.5%.

The Coexistence of Systemic Lupus Erythematosus and Psoriasis: Is It Possible?

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with various clinical disorders and frequent exacerbations. Psoriasis vulgaris is a common skin disorder which affect 1-3% of general populations. The pathophysiology regarding the coexistence of these diseases is not fully understood. Therapeutic challenges arise since the treatment one of these diseases may aggravate the other. We reported two cases of SLE with psoriasis vulgaris with clinical manifestations as recurrent erythroderma with photosensitivity. Improvement in clinical condition was observed after treating the patients with methylprednisolone combined with methotrexate. The coexistence SLE and psoriasis are considered very rare. The presence of this overlap syndrome may precede one another or occur simultaneously and is closely related with the presence of anti-Ro/SSA. Thus, it raises new challenge regarding its relationships, diagnosis, therapeutic, and management.

Acute Appendicitis in a Patient with Systemic Lupus Erythematosus.

Systemic lupus erythematosus (SLE) is a chronic excacerbative autoimmune disease with wide clinical spectrum. Gastrointestinal manifestasion is a frequent clinical manifestasion seen in SLE. Management with glucocorticoid and non-steroid anti-inflammatory drugs (NSAID) can mask the gastrointestinal symptoms in patient with SLE. One of the etiologies of gastrointestinal manifestations in SLE is acute appendicitis. Patients with acute appendicitis usually have abdominal pain as its chief complaint. The pathophysiology of acute appendicitis can occur primarily from SLE and secondary from other causes eg: infection, inflammation, etc. When a SLE patient has acute appendicitis as its initial assessment, determining its etiology is pivotal to give comprehensive management and preventing life-threatening complications.

Expectant management of preterm preeclampsia in Indonesia and the role of steroids.

OBJECTIVE: To present the outcome of expectant management of preterm preeclampsia in Indonesia, and the effect of ongoing treatment with methylprednisolone (MP) on maternal and perinatal outcome. MATERIAL AND METHODS: Prospective RCT on 48 patients with early-onset preeclampsia. Following the administration of dexamethasone for fetal lung maturation, patients were randomized to receive 25 mg MP group IV for the first week, decreasing to 12.5 mg during 2nd week and continued till birth, or matching IV placebo treatment (PL group). Prolongation of entry to delivery interval served as primary outcome measurement. RESULTS: The average time gained with expectant management was almost 14 days. However, there was no difference of mean time interval between entry to delivery between the PL (13.8 days) and MP (13.7 days) groups. Antenatal ongoing treatment with IV MP also did not improve maternal and/or perinatal outcome and might be associated with a higher risk for severe maternal infections--in particular tuberculosis. CONCLUSION: Expectant management of preterm preeclampsia is a realistic option in a major Indonesian perinatal referral center. Steroids (outside the use for fetal lung maturation) should not be used in the expectant management of preterm preeclampsia in Indonesia.
