Attrition at 24 weeks was similar in the MTX monotherapy and combination groups. Of the 370 evaluable participants in the initial MTX group, 28% achieved low levels of disease activity and did not step-up to combination therapy (MTX monotherapy group). The mean ± SD DAS28-ESR in participants continuing to take MTX monotherapy at week 102 was 2.7 ± 1.2, which is similar to that in participants who were randomized to immediate combination therapy (2.9 ± 1.2). Participants who received MTX monotherapy had less radiographic progression at week 102 as compared to those who received immediate combination therapy (mean ± SD change in modified Sharp score 0.2 ± 1.1 versus 1.1 ± 6.4). Participants assigned to initial MTX who required step-up to combination therapy at 24 weeks (72%) demonstrated similar DAS28-ESR values (3.5 ± 1.3 versus 3.2 ± 1.3 at week 48) and radiographic progression (change in modified Sharp score 1.2 ± 4.1 versus 1.1 ± 6.4 at week 102) as those assigned to immediate combination therapy. The results for either of the immediate combination approaches, whether triple therapy or MTX plus etanercept, were similar.

Numerous agents, including sulfasalazine, have been associated with agranulocytosis. Agranulocytic patients frequently experience life-threatening bacterial and fungal infections. Administration of colony stimulating factors may reduce the duration of agranulocytosis and incidence of life-threatening infections.

Sulphasalazine is a potent and selective inhibitor in vitro of prostaglandin 15-hydroxydehydrogenase in rabbit colon (ID50 = 50 micrometer) and in several other organs of different species, but does not inhibit prostaglandin delta-13 reductase or microsomal prostaglandin synthesis from arachidonic acid. It is suggested that this action may underly the therapeutic usefulness of sulphasalazine in ulcerative colitis for the prevention of relapse.

We constructed a Markov model to compare two strategies over 2 yr: (a) no maintenance 5-ASA, with 5-ASA 4.8 g/day given for flares, (b) maintenance 5-ASA 2.4 g/day, escalated and maintained at 4.8 g/day after the first flare. In both arms, the failure to induce remission led to other treatments, as needed: prednisone, parenteral corticosteroids, cyclosporine, 6-mercaptopurine, infliximab, and colectomy.

Computerized searches of bibliographic databases were carried out to identify studies published up to October 1993 that were randomized controlled trials of sulfasalazine or mesalazine as single drug therapy in the prevention of symptomatic disease relapse in quiescent Crohn's disease. We extracted and statistically aggregated data from the trials, using a fixed effects model.

The Peto odds ratio for the failure to maintain clinical or endoscopic remission (withdrawals and relapses) for 5-ASA versus placebo was 0. 47 (95% CI, 0.36 to 0.62) with an NNT of 6. These values were also calculated for the trials in which SASP and 5-ASA were compared, revealing an odds ratio of 1.29 (95% CI, 1.05 to 1.57), with a negative NNT value (-19), suggesting a higher degree of therapeutic effectiveness for SASP. SASP and 5-ASA had similar adverse event profiles, with odds ratios of 1.16(0.62 to 2.16), and 1.31(0.86 to 1.99), respectively. The NNH values were determined to be 171 and 78 respectively.

K pneumoniae specific antibody levels of both IgA1 and IgA2 subclasses were increased in the sera of patients with AS compared with healthy controls. The increased levels were present in patients with axial and with peripheral AS, and there were no statistically significant differences in the antibody levels between these two groups. Sulphasalazine treatment decreased the Klebsiella specific antibody level of IgA1 subclass in patients with axial AS, but there were no statistically significant changes in the IgA2 subclass, or in the patients with peripheral type AS.

Gliomas are among the most commonly diagnosed central nervous system tumors. Celecoxib has been utilized with success in the treatment of several types of cancer, including gliomas. The present study examined the antiproliferative effects of celecoxib and its benzimidazole-based analog, LLW-3-6, when used as co-treatment with sulfasalazine against human glioma LN18 cells. At 48-h treatment, the glioma cells maintained 60% viability in the presence of celecoxib or LLW-3-6 at the maximum concentration tested (40 μM). Co-treatment of glioma cells under a non-lethal dose (50 μM) of sulfasalazine and either celecoxib or LLW-3-6 (administered at different concentrations) resulted in improved inhibition of cell viability. The concentration of the molecules required to reduce cell growth in the combined treatment was significantly less than that needed when either molecule was administered independently. Based on computational values, LLW-3-6 has physiochemical characteristics that should allow for improved bioavailability in comparison to that of celecoxib.

MTX, SSZ, and antimalarials have become the most commonly used traditional DMARD for rheumatoid arthritis. Their use is more often limited by toxicity than by inefficacy. If tolerated, they can be retained for long periods of time.

The total volume as well as the total cost of drug consumption for RA in Sweden was relatively constant during our 11 year observation period, despite a notable increase in the use of DMARD. This was mainly due to a decrease in costs per DDD of NSAID, and an increased use of cyclosporine. Drug related adverse reactions were dominated by hematological reactions, and fatal events were few. This emphasizes the need for an extended evaluation of which safety procedures are most cost effective for monitoring the drugs used for RA.

After failure of medical therapy, children with refractory inflammatory bowel disease may require surgical intervention. In this article the authors describe one child in whom, after traditional therapies for refractory ulcerative colitis failed, full remission of the disease occurred after the addition of 6-mercaptopurine and cyclosporine A to her medical regimen. 6-Mercaptopurine has been used with increasing frequency in refractory inflammatory bowel disease; the use of cyclosporine A for this condition is still under investigation.

Psoriatic arthritis is an inflammatory arthritis, which occurs in up to 30% of individuals with psoriasis. Dermatologists and other physicians treating psoriasis are in an ideal position to screen for the condition, and with rheumatologists, strategize optimal therapy. Mild skin and joint manifestations may be treated effectively with topical agents, ultraviolet light therapy, and nonsteroidal anti-inflammatory drugs. More severe manifestations of the disease, including progressive peripheral joint damage, spine disease, enthesitis, dactylitis, and severe skin changes, require systemic therapy. Traditional systemic agents include methotrexate, sulfasalazine, and cyclosporine. When these agents are not adequate or not tolerated, new biologic agents, particularly anti-tumor necrosis factor (TNF) compounds, have shown significant and enduring benefit in all disease domains, improvement in quality of life and function, and inhibition of progressive joint damage.

A total of 160 patients (78 in the combination group and 82 in the single group) completed the 5-year extension study. At 2 years, 40% of the patients in the combination-DMARD group and 18% in the single-DMARD group had achieved remission (P < 0.009). At 5 years, the corresponding percentages were 28% and 22% (P not significant). The median Larsen radiologic damage scores at baseline, 2 years, and 5 years in the combination-DMARD and single-DMARD groups were 0 and 2 (P = 0.50), 4 and 12 (P = 0.005), and 11 and 24 (P = 0.001), respectively.

Although medication-induced colonotoxicity is uncommon, it is important that it be recognized, because the initial therapy for this condition is medication discontinuation. This review categorizes the association between the listed medications and colonotoxicity as "well-established" or "probable," according to the following criteria: number of clinical studies by independent clinical investigators, total number of reported cases, plausibility of an association based on experimental and pharmacologic studies, and validity of an association in each reported case. Medications associated with colonic ischemia include cocaine, ergotamine, estrogen, amphetamines, digitalis, methysergide, and vasopressin. Medications associated with colonic pseudoobstruction include narcotics, phenothiazines, vincristine, atropine or other anticholinergics, ganglionic blocking agents, and tricyclic antidepressants. Medications promoting infectious or necrotizing enterocolitis include numerous antibiotics associated with pseudomembranous colitis, deferoxamine associated with Yersinia enterocolitis, chemotherapy associated with neutropenic colitis, and hyperosmolar medications or formulas in infants. Medications associated with an allergic, inflammatory, or cytotoxic colitis include gold compounds, nonsteroidal antiinflammatory drugs, alpha-methyldopa, flucytosine, methotrexate, salicylates, and sulfasalazine. Potassium chloride, administered in slow-release wax matrices, can cause intestinal ulcers. Chronic cathartic use leads to colonic hypomotility and abdominal distention. Methysergide can cause a colonic stricture due to retroperitoneal fibrosis. Intrarectally administered compounds that have produced a toxic colitis include powerful acids, bases, and other corrosives. Enemas using hypertonic radiographic contrast agents have been associated with colitis in patients with colonic obstruction.

Since specific treatment has not yet been decided on for Crohn's disease, the immediate target is the induction of remission and its maintenance. We examined the effects of an elemental diet (ED) in Crohn's disease with special reference to the maintenance of remission. Eighty-four patients received total enteral nutrition with the ED (35 to 40 kcal/kg ideal body weight/day) and/or conventional drug treatment for induction of remission. Sixty-one patients in remission were then followed-up with prolonged ED therapy (home elemental enteral hyperalimentation, HEEH) and/or drugs. During the follow-up periods the course of patients receiving HEEH was better than those of patients without HEEH, namely the cumulative continuous remission rates after one, 2 and 4 years were, 94%, 63% and 63% in the group receiving HEEH, 75%, 66% and 66% in the group receiving HEEH and drugs, 63%, 42% and 0% in the group receiving drugs, and 50%, 33% and 0% in the group receiving no maintenance therapy, respectively. In particular, when more than 30 kcal/kg ideal body weight/day of the ED was given, the maintenance of remission was successful in 95% of the patients. These results indicated that ED therapy was effective not only for the induction of remission but also for the maintenance of remission in Crohn's disease.

Fifteen children followed as outpatients with chronic inflammatory disease of the colon were given sulfasalazine in doses from 1 to 4 gm/day (22 to 68 mg/kg, or 0.69 to 2.33 gm/m2). No correlation was found between the dose/m2 administered and the total serum sulfapyridine levels. However, 11 of 15 patients achieved SP levels greater than or equal to 17 micrograms/ml, a level approximating that reputedly associated with therapeutic efficacy. Patients who were either slow acetylators or slow hydroxylators of sulfapyridine had total SP levels significantly higher than patients who were both rapid acetylators and hydroxylators (20.0 +/- 1.2 vs 14.6 +/- 1.6). Total SP serum levels were not correlated with the activity of the disease. No toxic levels (greater than 50 micrograms/ml of SP) were encountered. We conclude that a dose of SASP in the range of 1.5 to 2.0 gm/m2 can be safely administered to children and is usually associated with serum SP levels considered in the therapeutic range. Although one-third of children are both rapid acetylators and hydroxylators and will have somewhat lower SP levels, the routine monitoring of SASP therapy with SP levels is not necessary for management of disease.

Significant clinical success of colon targeted dosage forms has been limited by their inappropriate release profile at the target site. Their failure to release the drug completely in the colon may be attributed to changes in the colonic milieu because of pathological state, drug effect and psychological stress accompanying the diseased state or, a combination of these. Alteration in normal colonic pH and bacterial picture leads to incomplete release of drug from the designed delivery system. We report the effectiveness of a targeted delivery system wherein the constant replenishment of the colonic microbiota is achieved by concomitant administration of probiotics along with the polysaccharide based drug delivery system. Guar gum coated spheroids of sulfasalazine were prepared. In the dissolution studies, these spheroids showed markedly higher release in the simulated colonic fluid. In vivo experiments conducted in rats clearly demonstrated the therapeutic advantage of co-administration of probiotics with guar gum coated spheroids. Our results suggest that concomitant use of probiotics along with the polysaccharide based delivery systems can be a simple strategy to achieve satisfactory colon targeting of drugs.

Rheumatoid arthritis (RA) is a systemic inflammatory arthritis that leads to severe joint damage and is associated with high morbidity and mortality. Disease-modifying antirheumatic drugs (DMARDs) are the mainstay of treatment in RA. DMARDs not only relieve the clinical signs and symptoms of RA but also inhibit the radiographic progression of disease. Recently, a new class of disease-modifying medications, the biologic agents, has been added to the existing spectrum of DMARDs in RA. However, patients' response to these agents is not uniform, with considerable variability in both efficacy and toxicity. There are no reliable means of predicting an individual patient's response to a given DMARD prior to initiation of therapy. In this chapter, the current published literature on the pharmacogenomics of traditional DMARDs and the newer biologic DMARDs in RA is highlighted. Pharmacogenomics may help individualize drug therapy in patients with RA in the near future.

The COBRA (Combinatietherapie Bij Reumatoide Artritis) multicenter trial compared the efficacy of prednisolone, methotrexate, and sulfasalazine against sulfasalazine alone in 155 patients with early RA. Two blinded observers interpreted radiographs in sequence (using the Sharp/Van der Heijde scoring system); in each center, one blinded observer performed clinical assessments every 3 months. The current analysis is based on clinical and radiologic data of the individual metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints of 135 patients. Conditional stepwise logistic regression analyzed the relationship between damage (progression) and clinical signs at baseline and followup for each of these joints individually in each patient.

Psoriatic arthritis affects 5% to 7% of patients with psoriasis. Genetic, immunologic, and environmental factors play a role in its pathogenesis. The role of inflammatory cytokines has been better defined buy azulfidine online , and recent immunohistochemical studies of the synovial membranes have shown important differences and similarities between psoriatic arthritis and rheumatoid arthritis. The association of psoriatic arthritis with infection, particularly HIV, remains an interesting observation. The most common clinical presentation appears to be peripheral polyarticular, and extra-articular manifestations including the SAPHO (synovitis, acne, pustulosis, hypertosis, and osteitis) syndrome are not common. Methotrexate and sulfasalazine therapy are effective in patients who do not respond to nonsteroidal anti-inflammatory drugs.

A spectrum of presenting features is possible, ranging from bone lesions alone to lesions combined with arthritis, palmoplantar pustulosis or psoriasis. The diagnosis was delayed from two weeks to five years. Roentgenographic evaluation was often normal at the beginning of the disease or showed nonspecific bone reactions. Radioisotope bone scans assisted in establishing the diagnosis and in identifying lesions that were initially clinically silent. Bone biopsies were performed in seven cases. Histopathological examination showed only mild inflammatory nonspecific changes. Microbiological cultures were always negative. Treatments were different according to the evolution of the disease and the hospital. There was no response to antibiotics in seven patients.

Clinical and laboratory factors influencing the discontinuation of second-line antirheumatic drugs were prospectively studied using survival analysis in a consecutive series of 245 patients with recently diagnosed rheumatoid arthritis. A statistically significant buy azulfidine online influence of age, sex, serum IgA and HLA-DR3 on the discontinuation rate of chrysotherapy because of toxicity was observed. The discontinuation of sulfasalazine was increased by advanced age and high rank order of prescription. With respect to efficacy, high initial disease activity appeared to predispose to treatment termination of hydroxychloroquine, sulfasalazine and penicillamine. Furthermore, an influence of the rank order of prescription on discontinuation of sulfasalazine therapy because of lack of efficacy was found. Of interest is that discontinuation of hydroxychloroquine therapy because of lack of efficacy occurred less frequently in HLA-DR3-positive than in HLA-DR3-negative patients. Although these prognostic factors are of secondary importance in clinical practice, they may be of significance in the interpretation and comparison of clinical trials.

Benzalazine (salicylazobenzoic acid, SAB), a 5-azo derivative of 5-aminosalicylic acid, has been designed as a new therapeutic agent for the treatment of inflammatory bowel disease which might lack the frequent side effects caused by the sulfapyridine moiety of the sulfasalazine molecule (SASP). Here, we report on a prospective, randomized, double-blind comparison of SAB and SASP in patients with an acute relapse of ulcerative colitis. 43 patients with an acute relapse of ulcerative colitis proven by the pertinent endoscopic-macroscopic and histologic criteria were randomized to receive a 6-week course of either 1 g SASP (n = 21) or the equivalent dose of 0.72 g SAB (n = 22) three times a day. Both groups were comparable with respect to demographic data, previous duration and extension of the disease as well as clinical, endoscopic and histologic severity of the relapse. 1 patient on SASP had to be removed from the study due to side effects, while 3 patients on SAB were removed due to buy azulfidine online rapid worsening of the disease requiring either surgery (1 patient with toxic megacolon) or additional steroid treatment (2 patients). 2 SAB patients were lost to follow-up after substantial improvement had been observed within the first 3 weeks of treatment. In the remaining patients (20 SASP, 17 SAB), stool frequency, stool consistency and macroscopic appearance as well as histology of the diseased mucosa were improved within 6 weeks, with no significant difference between the two groups with respect to any of the parameters recorded. Side effects were recorded in 5 patients on SASP (3 with nausea, 1 with pruritus and 1 with a generalized exanthema) and in 3 patients on SAB (all nausea and vomiting; difference not statistically significant). We conclude that SAB and SASP in equivalent doses are of similar efficacy in the treatment of active ulcerative colitis.

The chemical structures of four impurities isolated from sulfasalazine were determined. Three impurities are the by-products of the reaction process in drug synthesis, i.e., during diazotization of sulfapyridine and during coupling with salicylic acid. Only one contaminant was identified as a starting material, sulfapyridine, in the drug synthesis. The four impurities were characterized as 2-[[p-(2-pyridylsulfamoyl)-phenyl]azo]hydroxybenzene (I), 3-[[P-(2-pyridylsulfamoyl) phenyl]-azo]salicylic acid (II), 5-[[p-[4-(2-pyridylanilino)]-N-phenyl]azo]salicylic acid (III), and sulfapyridine (IV). Compounds I-III are novel molecules, and IV is the precursor of sulfasalazine. The isolation of the impurities was accomplished by TLC and liquid extraction procedures. The methods used to characterize the impurities were a combination of IR, UV, and NMR spectroscopy, mass spectrometry, and TLC. buy azulfidine online For I and III, comparisons also were made with the synthesized materials to supplement the evaluation.

The antifolates, methotrexate, aminopterin, 10-deazaaminopterin and sulfasalazine are clinically useful in the treatment of rheumatoid arthritis. Toxicity, rather than efficacy, appears to the the major factor limiting the usefulness of the classical antifolates (i.e., methotrexate and 10-deazaaminopterin). The fact that folate supplementation of methotrexate-treated rheumatoid arthritis patients reduces toxicity without altering efficacy also suggests that inhibition of the drug's target enzyme, dihydrofolate reductase, is not complete and not essential for efficacy. Since polyglutamates of methotrexate are direct inhibitors of thymidylate synthase and folate dependent enzymes of purine biosynthesis, the efficacy of this agent may involve blockade of these pathways. We hypothesize that blockage of aminoimidazole carboxamide ribotide transformylase, the folate dependent enzyme responsible for the insertion of carbon 2 into the purine ring, produces an immunosuppression mediated by secondary inhibition of adenosine deaminase, and S-adenosyl homocystein hydrolase by aminoimidazolecarboxamide metabolites. This mechanism of immunosuppression may explain the clinical effect buy azulfidine online of methotrexate, 10-deazaaminopterin, and possibly sulfasalazine. Since purine biosynthesis is a fundamental process, blockading this pathway may also decrease leukotriene production and interleukin-1 expression, which also could contribute to the efficacy of methotrexate.

Gliostatin/platelet-derived endothelial cell growth factor (GLS/PD-ECGF) is known to have both angiogenic and arthritogenic activities. The purpose of this study was to investigate whether disease-modifying anti-rheumatic drugs (DMARDs) and steroids are involved in the regulation of GLS expression. Fibroblast-like synoviocytes (FLSs) obtained from patients with rheumatoid arthritis (RA) were cultured and stimulated by interleukin (IL)-1beta with or without DMARDs and steroids. The expression levels of GLS Accutane Cost were determined using the reverse transcription-polymerase chain reaction and an ELISA. In cultured rheumatoid FLSs, the expression of GLS mRNA was significantly increased by stimulation with IL-1beta. By contrast, GLS mRNA levels in IL-1beta-stimulated FLSs were reduced by treatment with aurothioglucose (AuTG) and dexamethasone (DEX). These findings indicate that AuTG and DEX have anti-rheumatic activity, which is mediated via the suppression of GLS production. Neither methotrexate (MTX) nor sulfasalazine (SSZ) had a significant influence on GLS levels in our study.

Rheumatoid arthritis (RA) is an aggressive inflammatory disease in which chemokines are thought to recruit leukocytes and induce angiogenesis. The aim of Duloxetine Cymbalta Dose this study was to investigate the effects of sulfasalazine (SASP) and its metabolites, sulfapyridine (SP), and 5-aminosalicylic acid (5ASA) on chemokine production by RA synovial tissue explants and interleukin (IL)-1beta-stimulated RA synovial tissue fibroblasts using enzyme-linked immunosorbent assays and flow cytometry. Synovial tissue explants from RA patients secreted a decreased amount of the chemokines IL-8 and growth-related gene product alpha (GROalpha) when treated with SASP over a broad range of concentrations based on the typical clinical dosage of 2 g/day. SP had a significant effect in that it decreased RA synovial tissue explant secretion of IL-8 (22%), GROalpha (55%), and monocyte chemotactic protein-1 (MCP-1) (42%) (P < 0.05). 5ASA had no effect on RA synovial tissue explant production of IL-8 and MCP-1, while increasing GROalpha production. In IL-1beta-stimulated RA synovial tissue fibroblasts, SASP significantly increased chemokine secretion, while SP significantly decreased IL-8 (24%) and GROalpha (21%) secretion (P < 0.05). Flow cytometry showed that the number of IL-8 expressing RA synovial tissue fibroblasts did not significantly change following SP treatment. These data suggest that SASP may function to reduce inflammation in RA through the effects of its metabolite SP to reduce the secretion of the inflammatory chemokines IL-8, GROalpha, and MCP-1.

We performed a CE analysis comparing 6 treatment options for patients with MTX-resistant RA: 1) etanercept + MTX, 2) etanercept monotherapy, 3) cyclosporine + MTX, 4) triple therapy (hydroxychloroquine, sulfasalazine, and MTX), 5) continuation of MTX monotherapy, and 6) no second-line agent. A decision model was used with a time horizon of 6 months. We used 2 measures of effectiveness based on published clinical trial Ponstel Generic Name data: the American College of Rheumatology 20% response criteria (ACR 20); and a weighted average of proportions of patients achieving responses of ACR 70, ACR 50, and ACR 20 (ACR 70 weighted response [ACR 70WR]). Incremental CE ratios were calculated as the additional cost per patient achieving either outcome, compared with the next least expensive option. To help interpret CE relative to these RA-specific outcomes, we conducted a separate, "reference" CE analysis of MTX use in MTX-naive RA patients, using the same outcomes.

Malignant melanoma occurred in 11 patients with inflammatory bowel disease (IBD). Six cases occurred in patients with ileocolitis, two in regional enteritis, one in granulomatous colitis, and two in patients with ulcerative colitis. The mean age at development of IBD was 24 yr, and at development of melanoma was 40 yr: the mean duration from onset of IBD to development of melanoma was thus 16 yr. All patients for whom complete information was available, except two, had received steroids and azulfidine for approximately a decade, as well as blood transfusions, usually multiple, and on repeated occasions. Six of the 11 patients had undergone one to seven prior operations (mean 3.5). All patients had wide radical excision of the melanoma, with or without concomitant or subsequent nodal dissection. Two patients (ages 25 and 36 yr) died rapidly from widely disseminated malignant melanoma. These cases may be coincidental, or else there may be an association between IBD and melanoma, related to immunosuppression either from the disease itself, from the medical and surgical therapy, and/or from x-ray exposure.

A simple and rapid assay for quantitation of sulfasalazine metabolites in rat urine and plasma was developed using high-performance liquid chromatography (HPLC). The method involves dilution of urine or plasma samples (0.1 mL) with methanol for protein precipitation, followed by mixing and centrifugation at 10,000 x g. Chromatography was accomplished with a reversed-phase ODS C-18 column (5 mu; 4.6 x 250 mm). The mobile phase consisted of 20% methanol in 5.0 mM phosphate buffer (pH 6.0), with 0.5 mM tetrabutylammonium chloride as an ion-pairing agent. The flow rate was 1.7 mL/min. An injection volume of 30 microL was used and the metabolites were quantitated by an ultraviolet detector at 254 nm. Benzamide was used as the internal standard. This method is linear in the range of 0.5 to 25 micrograms/mL for 5-aminosalicylic acid (5-ASA), acetylsulfapyridine (Ac-SP), and acetyl-5-aminosalicylic acid (Ac-5-ASA), and from 0.25 to 25 micrograms/mL for sulfapyridine (SP). The percent relative standard deviation ranged from 1 to 7.9% for the metabolite standard curves and precision studies. The limit of detection for 5-ASA, Ac-SP, and Ac-5-ASA is 100 ng/mL, and for SP is 50 ng/mL, in both urine and plasma. This method is rapid, precise, and accurate, and has been used to determine sulfasalazine metabolites in individual rat plasma and urine samples following an oral dose of 60 mg/kg of sulfasalazine.

Women with IBD appear to be at increased risk of giving birth prematurely, having low-birth-weight infants, and having cesarean sections. Neither 5-aminosalicylic acid nor sulfasalazine has been found to increase the rate of major malformations, fetal mortality, or morbidity. There is conflicting evidence regarding the use of corticosteroids and azathioprine and 6-mercaptopurine. There are limited data on the use of infliximab during pregnancy, although no pattern of defects or complications has been reported to date.

We have previously reported that transduction of murine colon cancer cells (MC38) with herpes simplex virus thymidine kinase (HSV-tk) gene results in a significant enhancement of tumor growth rate in vivo and overexpression of cyclooxygenase-2 (COX-2). Our current study aimed to investigate the involvement of nuclear factor-kappa B (NF-kappaB), a pivotal transcriptional regulator of COX-2, in the upregulation of COX-2 expression by HSV-tk. It was found that HSV-tk gene transduction of MC38 cells results in significantly enhanced NF-kappaB activity, increased phosphorylation and degradation of inhibitor-kappa Balpha (IkappaBalpha) and enhanced translocation of NF-kappaB to the nucleus. Treatment of HSV-tk-transduced MC38 cells with sulfasalazine, a potent NF-kappaB inhibitor, led to dose-dependent inhibition of NF-kappaB activity, IkappaB phosphorylation and nuclear translocation of NF-kappaB, accompanied by significantly decreased COX-2 expression and reduced release of prostaglandin E2. Transient transfection experiments with COX-2 promoter constructs fused to luciferase reporter gene revealed that mutation in NF-kappaB-responsive element of COX-2 promoter significantly reduced promoter activity in HSV-tk-transduced MC38 and COS-7 cells, whereas it had no effect on promoter activity in the respective wild-type cells. At last, it was found that HSV-tk gene transduction causes significant enhancement of NF-kappaB activity and COX-2 expression in two additional tumor cell lines, 9L and T24. These findings suggest that HSV-tk gene transduction results in NF-kappaB pathway activation, which is essential for COX-2 overexpression by HSV-tk.

Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiological agent of primary effusion lymphoma (PEL), a rapidly progressing malignancy mostly arising in HIV-infected patients. Even under conventional chemotherapy, PEL continues to portend nearly 100% mortality within several months, which urgently requires novel therapeutic strategies. We have previously demonstrated that targeting xCT, an amino acid transporter for cystine/glutamate exchange, induces significant PEL cell apoptosis through regulation of multiple host and viral factors. More importantly, one of xCT selective inhibitors, Sulfasalazine (SASP), effectively prevents PEL tumor progression in an immune-deficient xenograft model. In the current study, we use Illumina microarray to explore the profile of genes altered by SASP treatment within 3 KSHV(+) PEL cell-lines, and discover that many genes involved in oxidative stress/antioxidant defense system, apoptosis/anti-apoptosis/cell death, and cellular response to unfolded proteins/topologically incorrect proteins are potentially regulated by xCT. We further validate 2 downstream candidates, OSGIN1 (oxidative stress-induced growth inhibitor 1) and XRCC5 (X-ray repair cross-complementing protein 5), and evaluate their functional relationship with PEL cell survival/proliferation and chemoresistance, respectively. Together, our data indicate that targeting these novel xCT-regulated downstream genes may represent a promising new therapeutic strategy against PEL and/or other AIDS-related lymphoma.

SAPHO syndrome is a disorder involving the skin, bone and joints. The underlying causes of SAPHO are poorly understood, and treatment is, therefore, directed towards the individual symptoms. However, many patients are refractory to treatment, and new treatment options are needed. Herein, we describe a 28-year-old patient with SAPHO syndrome and palmoplantar pustulosis seen at our hospital. Treatment was initiated with non-steroidal anti-inflammatory drugs, but clinical improvement was poor. The addition of sulfasalazine and oral alendronate also failed to alleviate symptoms. We subsequently commenced treatment with adalimumab 40 mg every 15 days and suspended bisphosphonates. Following 4 weeks' treatment with adalimumab, there was clear articular improvement and disappearance of palmoplantar pustulous lesions. Nocturnal inflammatory lumbar pain and global disease assessment were also improved. To our knowledge, this is the first report on the use of adalimumab for SAPHO. More studies are required to confirm our findings.

Psoriatic arthritis is a heterogeneous condition, the pattern of which is determined by any combination of pathology affecting peripheral joints, the enthesis and the spine. There is a paucity of evidence for most of the conventional agents used to treat psoriatic arthritis, with many of them being used on the basis of experience in rheumatoid arthritis. Herein, we summarise the evidence compiled relating to effectiveness of treatment for various manifestation of PsA. For those patients with progressive forms of arthritis who may benefit from intervention of newer biological therapies, the continued use of conventional therapy needs ever increasing scrutiny.
