Abstract
Coronavirus disease 2019 (COVID-19) is still an active global public health issue. Although vaccines and therapeutic options are available, some patients experience severe conditions and need critical care support. Hence, identifying key genes or proteins involved in immune-related severe COVID-19 is necessary to find or develop the targeted therapies. This study proposed a novel construction of an immune-related protein interaction network (IPIN) in severe cases with the use of a network diffusion technique on a human interactome network and transcriptomic data. Enrichment analysis revealed that the IPIN was mainly associated with antiviral, innate immune, apoptosis, cell division, and cell cycle regulation signaling pathways. Twenty-three proteins were identified as key proteins to find associated drugs. Finally, poly (I:C), mitomycin C, decitabine, gemcitabine, hydroxyurea, tamoxifen, and curcumin were the potential drugs interacting with the key proteins to heal severe COVID-19. In conclusion, IPIN can be a good representative network for the immune system that integrates the protein interaction network and transcriptomic data. Thus, the key proteins and target drugs in IPIN help to find a new treatment with the use of existing drugs to treat the disease apart from vaccination and conventional antiviral therapy.

Abstract
OBJECTIVES Rituximab is the front-line therapy for pemphigus disease. Although very effective, relapse rates are high. We assessed factors associated with disease remission and early relapse following the first rituximab cycle. MATERIAL AND METHODS A single center, retrospective cohort study of patients with pemphigus treated with rituximab (1000 mg days 0,14) at the Autoimmune Bullous Disease Clinic of the Division of Dermatology in Rabin Medical Center, Israel, between January 1, 1995 and March 31, 2020. RESULTS The cohort included 99 patients with a median follow-up of 37 months (range 12-155). After a single rituximab cycle, 74 patients (75%) achieved remission. Increased time to rituximab was associated with decreased remission rates (OR, 0.98 per month; 95%CI, 0.97-0.998). Of patients in remission with sufficient follow-up, 15/69 (22%) experienced an early relapse (≤12 months from remission). Prolonged time to rituximab and increased baseline disease severity, were associated with early relapse (OR, 1.02 per month; 95%CI, 1.001-1.04; OR, 1.04 per point; 95%CI, 1.01-1.08, accordingly). CONCLUSIONS Initiating rituximab early following diagnosis is recommended. Maintenance rituximab infusions, especially for patients with severe baseline disease, should be further investigated.

Abstract
In December 2019, a cluster of pneumonia caused by a novel coronavirus (2019-nCoV), officially known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged in Wuhan, Hubei province, China. Cytokine storm is an uncontrolled systemic inflammatory response resulting from the release of large amounts of pro-inflammatory cytokines and chemokines that occurs at phase 3 of viral infection. Such emergence led to the development of many clinical trials to discover efficient drugs and therapeutic protocols to fight with this single-stranded RNA virus. Corticosteroids suppress inflammation of the lungs during the cytokine storm, weaken immune responses, and inhibit the elimination of pathogen. For this reason, in COVID-19 corticosteroid therapy, systemic inhibition of inflammation is observed with a wide range of side effects. The present review discusses the effectiveness of the corticosteroid application in COVID-19 infection and the related side effects of these agents. In summary, a number of corticosteroids, including and especially methylprednisolone and dexamethasone, have demonstrated remarkable efficacy, particularly for COVID-19 patients who underwent mechanical ventilation.

Abstract
BACKGROUND A combined regimen of rituximab with corticosteroids for the treatment of pemphigus was effective in a prospective randomized controlled trial. OBJECTIVE To assess real-life response to rituximab in patients with pemphigus. METHODS A retrospective cohort of patients with pemphigus treated with ≥1 rituximab cycles (1,000 mg on days 0 and 14). The primary outcome was remission rate after 1 cycle. For efficacy analyses, a minimal 6-month follow-up was required. Adverse events were assessed in all patients. RESULTS The cohort included 117 patients for safety analysis, 108 for efficacy analysis (median follow-up of 33 months). All but one received concomitant corticosteroids, a third also received adjuvants. Overall, 80/108 patients (74%) achieved remission after the first rituximab cycle at a median of 5.5 months. Relapses occurred in 39 patients (49%) at a median of 18 months. Repeating treatment in relapsed patients increased remission rates to 75 and 88% after the second and third cycles, respectively. Adverse events were similar to those of previous publications. Two elderly patients died of infections attributable to rituximab combined with high-dose corticosteroids. CONCLUSION In a large real-life long-term cohort, rituximab with corticosteroids ± adjuvants induced remission in most patients with pemphigus, with relatively favorable safety. Repeating treatment following relapse or remission failure was beneficial.

Abstract
BACKGROUND Corticosteroids (CS) with or without adjuvant immunosuppressant agents are standard treatment for pemphigus vulgaris (PV). The efficacy of adjuvant therapies in minimizing steroid-related adverse events (AEs) is unproven. OBJECTIVES To utilize data collected in a French investigator-initiated, phase III, open-label, randomized controlled trial to demonstrate the efficacy and safety of rituximab and seek approval for its use in PV. METHODS This was an independently conducted post hoc analysis of the moderate-to-severe PV subset enrolled in the Ritux 3 study. Patients were randomized to rituximab plus 0·5 or 1·0 mg kg-1 per day prednisone tapered over 3 or 6 months, or 1·0 or 1·5 mg kg-1 per day prednisone alone tapered over 12 or 18 months, respectively (according to disease severity). The primary end point was complete remission at month 24 without CS (CRoff) for ≥ 2 months, and 24-month efficacy and safety results were also reported. RESULTS At month 24, 34 of 38 patients (90%) on rituximab plus prednisone achieved CRoff ≥ 2 months vs. 10 of 36 patients (28%) on prednisone alone. Median total cumulative prednisone dose was 5800 mg in the rituximab plus prednisone arm vs. 20 520 mg for prednisone alone. Eight of 36 patients (22%) who received prednisone alone withdrew from treatment owing to AEs; one rituximab-plus-prednisone patient withdrew due to pregnancy. Overall, 24 of 36 patients (67%) on prednisone alone experienced a grade 3/4 CS-related AE vs. 13 of 38 patients (34%) on rituximab plus prednisone. CONCLUSIONS In patients with moderate-to-severe PV, rituximab plus short-term prednisone was more effective than prednisone alone. Patients treated with rituximab had less CS exposure and were less likely to experience severe or life-threatening CS-related AEs. What's already known about this topic? Pemphigus vulgaris (PV) is the most common type of pemphigus. Corticosteroids, a standard first-line treatment for PV, have significant side-effects. Although their effects are unproven, adjuvant corticosteroid-sparing agents are routinely used to minimize steroid exposure and corticosteroid-related side-effects. There is evidence that the anti-CD20 antibody rituximab is effective in the treatment of patients with severe recalcitrant pemphigus and in patients with newly diagnosed pemphigus. What does this study add? This study provides a more detailed analysis of patients with PV enrolled in an investigator-initiated trial. Rituximab plus prednisone had a steroid-sparing effect and more patients achieved complete remission off prednisone. Fewer patients experienced grade 3 or grade 4 steroid-related adverse events than those on prednisone alone. This collaboration between academia and industry, utilizing independent post hoc analyses, led to regulatory authority approvals of rituximab in moderate-to-severe PV.

Abstract
BACKGROUND Various systemic agents have been assessed for the treatment of alopecia areata (AA); however, there is a paucity of comparative studies. OBJECTIVE To assess and compare cyclosporine and betamethasone minipulse therapy as treatments for AA with regard to effectiveness and safety. METHODS Data were collected from 88 patients who received at least 3 months of oral cyclosporine (n=51) or betamethasone minipulse therapy (n=37) for AA. Patients with ≥50% of terminal hair regrowth in the alopecic area were considered responders. RESULTS The responder of the cyclosporine group was 54.9% and that of the betamethasone minipulse group was 37.8%. In the cyclosporine group, patients with mild AA were found to respond better to the treatment. Based on the patient self-assessments, 70.6% of patients in the cyclosporine group and 43.2% of patients in the betamethasone minipulse group rated their hair regrowth as excellent or good. Side effects were less frequent in the cyclosporine group. CONCLUSION Oral cyclosporine appeared to be superior to betamethasone minipulse therapy in terms of treatment effectiveness and safety.

Abstract
Treatment of autoimmune haemolytic anaemia is still a challenge to clinicians. Even today it may be lethal. Half of the cases are secondary due to an underlying disease, and the others are primary or idiopathic cases. According to the specificity and type of autoantibodies there are warm and cold type forms of autoimmune haemolytic anaemia. The hallmark of the diagnosis is to detect the presence of haemolysis by clinical and laboratory signs and detect the underlying autoantibodies. Treatment of autoimmune haemolytic anaemia is still a challenge to clinicians. We still loose patients due to excessive haemolysis or severe infections caused by immunosuppression. First line treatment is corticosteroids. Other immunosuppressive agents like: cyclophosphamide, azathioprine, cyclosporine or the off label rituximab can be used in case of corticosteroid refractoriness. Splenectomy is a considerable option in selective cases. The authors discuss treatment options and highlight difficulties by presenting 4 cases. Orv. Hetil., 2015, 156(11), 449–456.

Abstract
BACKGROUND Rituximab is increasingly being appreciated as a remarkably effective treatment for pemphigus, mostly concomitantly with other immunosuppressive medications. The majority of studies have used a single cycle of rituximab with the same dosage as approved for the treatment of lymphomas, ie, 375 mg/m(2) weekly × 4 weeks. Rituximab is also approved for the treatment of rheumatoid arthritis, with a different dosing regimen: 1000 mg × 2, days 1 and 15. OBJECTIVE We aimed to assess the clinical response of patients with pemphigus to a single cycle of rituximab at the dosage used in rheumatoid arthritis. We also evaluated the response to repeated cycles of rituximab. METHODS A total of 47 patients with pemphigus who were treated with rituximab at a dosage of 1000 mg × 2, days 1 and 15, most with concurrent immunosuppressive medications, were retrospectively studied. RESULTS Remission rates after the first treatment cycle reached 76%. Repeating the treatment further increased the remission rates to 91%. There was a 22% relapse rate at a median time of 8 months, but 75% of relapsing patients achieved remission again with additional cycles. The side-effect profile was similar to previous reports, except for an immediate postinfusion pemphigus exacerbation in 4 patients. LIMITATIONS This was a retrospective study with a limited follow-up period. CONCLUSION The rheumatoid arthritis dosage of rituximab was efficacious and well tolerated in patients with pemphigus. Patients who fail to achieve remission after 1 cycle or patients who relapse seem to benefit from repeated rituximab cycles.

Abstract
The anti-inflammatory effects of fuciodan and Cistanche tubulosa (CT) extract were investigated in vitro macrophage culture system and in vivo carrageenan-induced air pouch inflammation model. CT extract inhibited nitric oxide production from activated RAW 264.7 macrophage cells, while fucoidan was inactive. In vivo air pouch inflammation model, carrageenan-induced vascular exudation and increased nitric oxide and prostaglandin E2 concentrations in the exudates were synergistically suppressed by co-administration of fucoidan or CT extract. Moreover, tissue inflammation was substantially attenuated by the combinational therapy. However, there was no synergistic effect against the inflammatory cell infiltration, although fucoidan and CT extract each markedly reduced the cell numbers. Therefore, it is suggested that fucoidan blocks infiltration of inflammatory cells, while CT extract inhibits activation of the cells, and that their combinational treatment could be a promising candidate for the relief of various types of inflammation.

Abstract
Despite a number of studies on steroid therapy as a prophylactic measure in fat embolism syndrome (FES), there is no universal agreement about its role in this critical situation. The present article attempts to search the available literature, and provides a more lucid picture to the readers on this issue. Seven articles (total 483 patients) were reviewed and analyzed. Total of 223 patients received steroid (methyl prednisolone sodium succinate), while the remaining 260 patients formed the control population. Among these subjects, 9 patients in steroid-receiving group and 60 patients in the control group developed FES (P < 0.05). The lack of uniformities in these studies, variable dose and single-center trial are the principal limitations and confuses the surgeons to have definite conclusion. Large-scale, more uniformly designed, multi-centered, randomized, prospective trials are needed to determine the correct situations and dosage in which steroids provide the maximum benefit (with the least possible risk).

The anti-arthritic and anti-oxidative effect of NBD (6-nitro-1,3-benzodioxane) in adjuvant-induced arthritis (AIA) in rats. Inflamm Res 2012; 61:875-87. [PMID: 22538965 DOI: 10.1007/s00011-012-0480-4] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2011] [Revised: 04/07/2012] [Accepted: 04/11/2012] [Indexed: 10/28/2022] Open
Abstract
OBJECTIVES The present study evaluated the anti-arthritic and anti-oxidative effects of 6-nitro-1,3-benzodioxane in the adjuvant-induced arthritis model in rats. METHODS Arthritis was induced in female rats by intradermal injection of MT37Ra. Arthritis was evaluated by arthritic score, body weight loss, paw volume measurement, and histological changes. The plantar test was used to evaluate the effect of NBD on hyperalgesia. RESULTS The hyperalgesia (p < 0.0001) and hind paw inflammation (p < 0.034) was significantly decreased with parallel increase in the body weight of the NBD-treated (25 mg/kg) group compared to arthritic control rats. The antioxidant activity analysis demonstrated that the treatment of NBD significantly suppressed the levels of nitric oxide (p < 0.001) and peroxide (p < 0.002) with a significant increase in the glutathione (p < 0.021) compared to the arthritic control group. Since the IL-1β and TNF-α are key pro-inflammatory cytokines in arthritis, we therefore measured their levels in the serum samples. In comparison to the arthritic control group, the NBD treatment significantly reduced the levels of IL-1β (p < 0.003) and TNF-α (p < 0.026). CONCLUSION Our results suggests that NBD is an anti-arthritic agent that not only reduces the severity of the disease process but also affects contributing factors of arthritic inflammation including free radicals and inflammatory cytokines production.

Abstract
OBJECTIVE Glucosamine is a naturally occurring amino monosaccharide that maintains the elasticity and strength of the cartilage tissues. It has been used to treat osteoarthritis in humans; however, in severe conditions of inflammation and pain, glucosamine alone is not enough, and it is important to improve its biological activity. Our research group has recently taken an interest in the synthetic manipulation of amino sugars to develop some efficient pharmacophores, e.g., β-D-glucosamine, to combat rheumatoid arthritis, and tested its anti-arthritic effects in the collagen-induced arthritis (CIA) model in rats. METHODS Arthritis was induced in female Sprague-Dawley rats by multiple intradermal injections of bovine type II collagen and challenged again with the same antigen preparation 7 days later. Arthritis was evaluated by arthritic score, body weight loss, paw volume measurement, and histological changes. RESULTS The animals in the arthritic control group showed a gradual decrease in their body weight and concurrent increase in the paw volumes compared to the normal control group. In contrast, increased hind paw swelling was significantly suppressed with no further noticeable reduction in body weight in the glucosamine (p < 0.05) and GN1-treated (p < 0.02) arthritic animals. Histopathological evaluation of isolated knee joints by grading system and classification of the stages in arthritic lesion development revealed suppression of the inflammatory changes in the GN1-treated animals. Moreover, both the pro-inflammatory markers C-reactive protein (CRP) and low-density lipoprotein (LDL) levels were found to be significantly decreased in animals treated with GN1 (p < 0.03 for CRP and p < 0.05 for LDL) compared to the arthritic control group. CONCLUSION These results suggest that GN1 has both anti-arthritic and anti-inflammatory properties. Its effects in the CIA model suggest that it could be useful in the treatment of rheumatoid arthritis.

Abstract
Many therapeutic modalities have been used to treat alopecia areata, with variable efficacy and safety profiles. Unfortunately, none of these agents is curative or preventive. Also, many of these therapeutic agents have not been subjected to randomized, controlled trials, and, except for topical immunotherapy, there are few published studies on long-term outcomes. The treatment plan is designed according to the patient's age and extent of disease. In this paper, the therapeutic agents are organized according to their efficacy and safety profiles into first-line, second-line, and third-line options.

Abstract
PURPOSE To evaluate whether intravitreal fluocinolone acetonide (FA) implantation (Retisert) leads to scleral thinning. METHODS Scleral thickness was measured at the pars plana region (4 quadrants) with anterior segment OCT (Visante) in FA implanted eyes (18) with noninfectious posterior uveitis in comparison to eyes with prior vitrectomy (8), and normal eyes without prior surgery (30). RESULTS Mean scleral thickness in normal (nonsurgical) eyes was 0.99/0.93/0.88/0.86, and 0.92 mm in the inferonasal/inferotemporal/superotemporal/superonasal quadrants, and overall, respectively. Sclera was thinner in each quadrant of the FA implanted eyes compared to the fellow or nonsurgical eyes, although none reached statistical significance, as the differences were small. However, a few FA implanted eyes demonstrated more dramatic scleral thinning than others. CONCLUSIONS FA implant appears to lead to statistically nonsignificant scleral thinning overall with few exceptions. Clinicians should be aware of potential scleral thinning in select cases, important for reimplantation and long-term follow-up.

Abstract
The present study was carried out to study the anti-arthritic and anti-inflammatory activity of N-(2-hydroxy phenyl) acetamide in adjuvant-induced arthritis in adult female Sprague Dawley rats. During experimental period, body weight and paw oedema volume were observed. At the end of each experiment, plasma and serum samples were collected and used for estimation of pro-inflammatory cytokines IL-1 beta and TNF-alpha and oxidative stress markers i.e., nitric oxide, peroxide and GSH. Our results suggested that, the reduction in body weight and increase in paw oedema volume were significantly retarded in the AIA rats receiving 5mg/kg and 10mg/kg doses of N-(2-hydroxy phenyl) acetamide as compared to diseased control animals. The serum levels of IL-1 beta and TNF-alpha were reduced as compared to those in the diseased control group. Treatment with N-(2-hydroxy phenyl) acetamide also altered oxidative stress markers in relation to its anti-inflammatory activity. Based on our results, it can be concluded that N-(2-hydroxy phenyl) acetamide possesses promising anti-arthritic property.

Abstract
The anti-inflammatory effects of an ethanol extract of Angelica gigas (EAG) were investigated in vitro and in vivo using croton oil-induced inflammation models. Croton oil (20 microg/mL) up-regulated mRNA expression of cyclooxygenase (COX)-I and COX-II in the macrophage cell line, RAW 264.7, resulting in the release of high concentrations of prostaglandin E(2) (PGE(2)). EAG (1 approximately 10 microg/mL) markedly suppressed croton oil-induced COX-II mRNA expression and PGE(2) production. Application of croton oil (5% in acetone) to mouse ears caused severe local erythema, edema and vascular leakage, which were significantly attenuated by oral pre-treatment with EAG (50 approximately 500 mg/kg). Croton oil dramatically increased blood levels of interleukin (IL)-6 and PGE(2) without affecting tumor-necrosis factor (TNF)-alpha and nitric oxide (NO) levels. EAG pre-treatment remarkably lowered IL-6 and PGE(2), but did not alter TNF-alpha or NO concentrations. These results indicate that EAG attenuates inflammatory responses in part by blocking the COX - PGE(2) pathway. Therefore, EAG could be a promising candidate for the treatment of inflammatory diseases.

Abstract
UNLABELLED Various therapeutic agents have been described for the treatment of alopecia areata (AA), but none are curative or preventive. The aim of AA treatment is to suppress the activity of the disease. The high rate of spontaneous remission and the paucity of randomized, double-blind, placebo-controlled studies make the evidence-based assessment of these therapies difficult. The second part of this two-part series on AA discusses treatment options in detail and suggests treatment plans according to specific disease presentation. It also reviews recently reported experimental treatment options and potential directions for future disease management. LEARNING OBJECTIVES After completing this learning activity, participants should be able to compare the efficacy and safety of various treatment options, formulate a treatment plan tailored to individual patients, and recognize recently described treatments and potential therapeutic approaches.

Abstract
Anti-inflammatory effects of an ethanol extract of Angelica gigas (EAG; 50, 160, or 500 mg/kg) were investigated in a carrageenan-induced air pouch inflammation model. Injection of 1 ml of carrageenan (1%) into mouse air pouches markedly increased the exudate volume and exudate albumin concentration, which were significantly attenuated by oral pretreatment with EAG. EAG also markedly reduced carrageenan-induced infiltrations of neutrophils, monocytes, and lymphocytes, but did not influence eosinophils or basophils. Carrageenan dramatically increased levels of tumor necrosis factor-alpha and interleukin-6, which might be derived from the infiltrated cells. It also elevated nitric oxide, and slightly increased prostaglandin E(2). EAG pretreatment significantly lowered tumor necrosis factor-alpha and nitric oxide, but did not alter interleukin-6 or prostaglandin E(2) levels. These results indicate that EAG attenuates some inflammatory responses by blocking the tumor necrosis factor-alpha-nitric oxide pathway, and that EAG could be a promising anti-inflammatory drug candidate for inflammatory diseases.

Abstract
Voluntary exercise is associated with the prevention and treatment of numerous physical and psychological illnesses, yet the mechanisms by which it confers this protection remain unclear. In contrast, stress, particularly under conditions of prolonged or repeated exposure when glucocorticoid levels are consistently elevated, can have a devastating impact on health. It has been suggested that the benefits of physical exercise may lie in an ability to reduce some of the more deleterious health effects of stress and stress hormones. The present series of experiments provides evidence that voluntary exercise facilitates habituation of corticosterone but not adrenocorticotropin hormone responses to repeated stress presentations. After 6 weeks of running wheel access or sedentary housing conditions, rats were exposed to 11 consecutive daily 30 min presentations of 98 dB noise stress. Similar corticosterone responses in exercised rats and sedentary controls were observed following the first, acute stress presentation. While both groups demonstrated habituation of corticosterone secretory responses with repeated noise stress exposures, the rate of habituation was significantly facilitated in exercised animals. These results suggest that voluntary exercise may reduce the negative impact of prolonged or repeated stress on health by enhancing habituation of the corticosterone response ultimately reducing the amount of glucocorticoids the body and brain are exposed to.

Abstract
In the present study, azothioprine, chloroquine, D-penicillamine, methotrexate and sodium aurothiomalate (gold salt) were evaluated for possible disease-modifying effects in the adjuvant-induced arthritis model of human rheumatoid arthritis in rats. Gait analysis was used to examine the role of disease-modifying antirheumatic drugs in the development of pain. Body weights were also measured to monitor the progression of disease and the systemic antiarthritic effects of the test compounds used in this study, as well as their systemic toxicity. Our results showed that azothioprine (5 mg/kg/day), chloroquine (12.5 mg/kg/day), sodium aurothiomalate (2.5 mg/kg/day) and methotrexate (1 mg/kg/week) not only inhibited the macroscopic changes such as erythema and swelling of limbs, but also exhibited significant reversal of gait deficits seen in the untreated or saline-treated arthritic rats. No reduction in the body weights were observed in the arthritic rats treated with azothioprine, chloroquine, sodium aurothiomalate and methotrexate. D-Penicillamine (12.5 mg/kg/day), however, showed a significant reduction (P < 0.03) in the body weights of the arthritic rats over a period of 22 days; furthermore, it was unable to show any reduction in arthritic score (P < 0.1). In earlier experiments, chloroquine and methotrexate failed to suppress carageenan-induced edema, suggesting that the mode of antiarthritic action may be different from those of nonsteroidal anti-inflammatory agents. Since these disease-modifying antirheumatic drugs are reported to have an immunomodulatory role, especially the gold salt, which influences the monocyte–macrophage system, it is suggested that the observed antiarthritic effects of disease-modifying antirheumatic drugs may be partly attributed to their immunomodulatory activity.

Abstract
Background: Physicians frequently prescribe short-term corticosteroids (CSs) to treat acute and self-limiting diseases. Standard texts and articles do not usually discuss the possible, although infrequent, risks of short-term CSs. Objective: To demonstrate that side effects, although uncommon, can occur with short-term CSs and that these can occasionally be serious. Methods: Medline peer review literature in English (1985–2006) was searched to identify the potential risks of CSs. Standard textbooks of dermatology, gastroenterology, ophthalmology, pharmacology, respirology, and rheumatology were reviewed. Because the results showed some factual discordance and a dearth of precise data, the results for each body system were reviewed with two relevant clinical specialists at North York General Hospital (with at least 20 years' experience). Further information was obtained from a questionnaire of 200 physicians in North York General Hospital and by feedback from an additional 100 physicians during a presentation of this material at the American Academy of Dermatology. Results: Short-term CSs are generally safe, but there have been numerous reports of associated avascular necrosis and a few cases of fatal varicella-zoster in immunocompetent patients. Severe mood changes and psychotic reactions rarely occur unpredictably with short-term CSs. These events are rare, and most treatments with short-term CSs are problem free. Conclusions: Problems are infrequent, but patients must be informed of all material risks and treatment options. Thorough chart documentation is required, and patient consent must be given. CS doses should be as low as possible, and CS courses should be as infrequent and as short as possible. The literature reviewed in this article clearly indicates that a short course of CS of 1 week, in the absence of specific contraindications, is unlikely to be harmful (psychotic or prepsychotic episodes possibly excepted).

Abstract
The present study revealed the synergistic effect of boswellic acid mixture (BA) and glucosamine for anti-inflammatory and anti-arthritic activities in rats. Two studies were conducted, that is, acute anti-inflammatory by carrageenan edema and chronic anti-arthritic by Mycobacterium-induced developing arthritis. Five groups of animals were included in each of the study: the vehicle control, positive control (ibuprofen 100mg/kg), boswellic acids (250 mg/kg), glucosamine (250 mg/kg) and a combination of boswellic acids (125 mg/kg) and glucosamine (125 mg/kg). BA when administered at 250 mg/kg in rats, carrageenan-induced paw edema and Mycobacterium-induced developing arthritis were significantly inhibited. In comparison to boswellic acids, glucosamine when administered at 250 mg/kg showed a mild effect in carrageenan-induced edema and moderate inhibition of paw swelling against developing arthritis. Although the combination of boswellic acids and glucosamine did not affect the acute inflammation to a greater extent yet a significant anti-arthritic activity was observed in rats. In conclusion, a synergistic effect was observed in chronic inflammatory conditions when two chemical entities were administered in combination in preclinical study.

Abstract
The focus of care for patients with brain metastases will always be on therapeutic options such as surgery, radiotherapy, and chemotherapy. However, proper symptom management and supportive care of non-therapeutic issues will be equally as important, including treatment of seizures, use of anticonvulsants, corticosteroids, and gastric acid inhibitors, assessment of swallowing dysfunction, treatment of thromboembolic events, appropriate use, and safe application of anticoagulation, and evaluation of psychiatric issues. Appropriate management of these supportive aspects of patient care will improve overall quality of life and allow the patient and family to more easily concentrate on treatment.

Abstract
The most common medical problems in brain tumor patients include the management of seizures, peritumoral edema, medication side effects, venous thromboembolism (VTE), fatigue and cognitive dysfunction. Despite their importance, there are relatively few studies specifically addressing these issues. There is increasing evidence that brain tumor patients who have not had a seizure do not benefit from prophylactic antiepileptic medications. Patients on corticosteroids are at greater risk of Pneumocystis jerovecii pneumonia and may benefit from prophylactic therapy. There is also growing evidence suggesting that anticoagulation may be more effective than inferior vena cava IVC) filtration devices for treating VTE in brain tumor patients and the risk of hemorrhage with anticoagulation is relatively small. Low-molecular weight heparin may be more effective than coumadin. Medications such as modafinil and methylphenidate have assumed an increasing role in the treatment of fatigue, while donepezil and memantine may be helpful with memory loss.

Abstract
A subretinal drug delivery system was developed to overcome the limitations of current treatments for retinal disease. A rod-shaped implant was made by embedding the corticosteroid triamcinolone acetonide within a biodegradable polycaprolactone polymer matrix. The implant was fabricated by homogeneously mixing the polymer and drug in solvent. The mixture was then dried, melted, and extruded, and the prepared solid form was drawn into a filament. The rods were mechanically sectioned to a length of 2 mm with a diameter of up to 320 microm. The rods were successfully implanted into the subretinal space of six rabbits. No complications were observed during the 4-week follow-up period. Initial observations of the implantation and elution characteristics revealed that polycaprolactone is well tolerated by the retinal tissue and that the implant can elute steroid for a period of at least 4 weeks without eliciting inflammatory response or complications. In vitro drug elution rates of different polymer to drug ratios and geometries into a balanced salt solution/bovine serum albumin (1%) solution showed an early rapid-release phase and late first-order phase. Histology and device retrieval after implantation revealed minimal encapsulation and good preservation of cellular morphology during the follow-up period and a more fibrous polymer microstructure of the implant.

Abstract
Pemphigus is a rare autoimmune disease that results in blistering of the skin and oral cavity. It is caused by autoantibodies directed against cell-surface antigens on keratinocytes, which when targeted lose their cellular adhesion properties and separate from one another to form blisters within the epidermis. Differences in the particular antigens targeted by the antibodies and in the distribution of these antigens in the different regions of the body and in the separate layers of the epidermis result in different clinical manifestations of the disease. The disease is diagnosed based on its clinical manifestations (flaccid blisters and erosions on skin and oral mucosa), histology (epidermal acantholysis), and immunological abnormalities (circulating and tissue-fixed antibodies against keratinocyte surface antigens). Pemphigus, which if left untreated is almost always fatal, is generally managed with topical, oral, or intralesional corticosteroids. Other options include plasmapheresis and intravenous immunoglobulin (IVIg), coupled with cytotoxic drugs. Immunosupressants, anti-inflammatory drugs, and antibiotics are used as adjuvants, but apart from IVIg, these therapy options are non-specific and more research is needed to develop treatments with improved side-effect profiles.

Abstract
This study evaluated the antiinflammatory activities of pinitol and glucosamine either alone or in combination against carrageenan- and cotton pellet-induced acute and subacute inflammation in rats. Five groups were included in each of the acute and subacute inflammation studies: the vehicle control group, positive control group (aminopyrine 100 mg/kg), pinitol group (20 mg/kg), glucosamine group (25 mg/kg) and a pinitol (20 mg/kg) and glucosamine (25 mg/kg) combination group. When 20 mg/kg of pinitol was administered to the rats, paw edema induced by the carrageenan injection was significantly suppressed and the level of granuloma formation induced by the cotton pellet implantation was slightly reduced. When 25 mg/kg of glucosamine was administered, paw edema caused by the acute inflammation was slightly reduced and the level of granuloma formation caused by the subacute inflammation was strongly suppressed. Although the combined application of pinitol and glucosamine did not have an additional antiinflammatory effect on the paw edema caused by acute inflammation, it did have an increased antiinflammatory effect on the formation of granuloma induced by subacute inflammation. Therefore, pinitol and glucosamine have an antiinflammatory effect on acute and subacute conditions. Moreover, a synergistic antiinflammatory effect against subacute inflammation was observed when the two chemicals were administered in combination.

Abstract
Glucocorticoids are frequently used to treat patients with pulmonary diseases, but continuous long-term use of glucocorticoids may lead to significant bone loss and an increased risk of fragility fractures. Patients with certain lung diseases, regardless of pharmacotherapy-particularly COPD and cystic fibrosis-and patients waiting for lung transplantation are also at increased risk of osteoporosis. Fragility fractures, especially of the hip, will have substantial effects on the health and well-being of older patients. Vertebral collapse and kyphosis secondary to glucocorticoid-induced osteoporosis (GIO) may affect lung function. Identification of patients with osteopenia, osteoporosis, or fragility fractures related to osteoporosis is strongly recommended and should lead to appropriate treatment. Prevention of GIO in patients receiving continuous oral glucocorticoids is also recommended. In patients receiving either high-dose inhaled glucocorticoids or low- to medium-dose inhaled glucocorticoids with frequent courses of oral glucocorticoids, bone mineral density measurements should be performed to screen for osteopenia and osteoporosis. A bisphosphonate (risedronate or alendronate), calcium and vitamin D supplementation, and lifestyle modifications are recommended for the prevention and treatment of GIO.

Abstract
The efficacy of a minimum dose of methylprednisolone for the prevention of posttraumatic hypoxaemia and fat embolism syndrome (FES) was prospectively studied in 87 patients with isolated, closed or grade I open, femoral and tibial fractures. On admission, the patients were randomly allocated either to a control group given placebo (40 patients) or to a methylprednisolone-treated group (47 patients). A total dose of 6 mg/kg BW methylprednisolone (SoluMedrol, Upjohn) was administered intravenously, divided in six equal doses at 8 h intervals. Six patients (12.8%) in the control group and one patient (2.5%) in the trial group developed FES (P = 0.079) but the difference is not statistically significant. Twenty-four hours after admission, the steroid-treated patients displayed statistically significant higher p(O2) values compared to the control group (P = 0.035) and this difference persisted on the second and the third post-admission day as well (P = 0.008). No corticosteroid-related side-effects were noticed in any of the patients during hospitalisation. Our results support the prophylactic administration of methylprednisolone in small dosage to prevent posttraumatic hypoxaemia and probably FES in patients with isolated lower limb long bone fractures, especially when early fracture stabilisation is not possible.

Abstract
OBJECTIVE To demonstrate the possible beneficial effects of methotrexate (MTX) therapy for patients with sarcoid-associated optic neuropathy (SAON). DESIGN Retrospective, noncomparative, interventional case series. PARTICIPANTS Three patients diagnosed with SAON who received MTX. Two patients had tissue biopsies consistent with sarcoidosis, and 1 patient had clinically diagnosed sarcoidosis based on laboratory and radiographic studies. All 3 patients developed side effects with corticosteroid treatment of their optic neuropathy. INTERVENTION Patients were treated with weekly doses of oral MTX and monitored with neuro-ophthalmic, medical, and laboratory examinations. MAIN OUTCOME MEASURES Visual acuity, automated perimetry, and reduction of oral prednisone therapy. RESULTS After initiation of MTX, all 3 patients showed an improvement or stabilization of visual acuity. All patients had a decrease in their corticosteroid requirements, and all had improved or stabilized visual field deficits. One of the 3 patients developed leukopenia that necessitated a reduction of the methotrexate dose. CONCLUSION Methotrexate may be effective for SAON as an adjunct to corticosteroid therapy or as an alternative for corticosteroid-intolerant patients. Oral MTX reduced the corticosteroid requirements of 3 patients with SAON, and all 3 demonstrated stable or improved visual function.

Abstract
The spectrum of occupational diseases most commonly seen in the food industry includes occupational asthma, rhinitis, conjunctivitis, dermatitis, and hypersensitivity pneumonitis. Occupational asthma represents between 3% and 20% of all asthma cases and is the most common form of occupational lung disease. Occupational skin diseases may represent between 10% and 15% of all occupational diseases, and they have significant economic impact. Hypersensitivity pneumonitis affects the food industry, with farmer's lung representing a common form of the disease. Each of these diseases may have serious and potentially irreversible effects on the health of a farmer, food processor, or food preparer, even after removal of the offending exposure.

Abstract
Treatment of autoimmune hemolytic anemias varies depending on whether the patient has autoimmune hemolytic anemia of warm antibody type, cold agglutinin syndrome, paroxysmal cold hemoglobinuria, or autoimmune hemolytic anemia secondary to an underlying disorder. Initial therapy for warm antibody autoimmune hemolytic anemia should be corticosteroids, such as prednisone at conventional doses of 1 to 1.5 mg/kg/d orally. Criteria must be established to determine whether the therapeutic response is adequate, because long-term therapy may lead to significant detrimental side effects. Splenectomy has the advantage over therapeutic options in that it has the potential for complete and long-term remission. The major adverse effect is the syndrome of overwhelming postsplenectomy infection. Other therapeutic options, which are less likely to have long-term benefit, are immunosuppressive drugs, danazol, intravenous immunoglobulin, and plasma exchange. Therapy of cold agglutinin syndrome often is unsatisfactory. All patients should avoid exposure to cold, and if additional therapy is necessary, the therapies used for warm antibody autoimmune hemolytic anemia may be tried with less likelihood of response. Paroxysmal cold hemoglobinuria requires aggressive supportive therapy, generally supplemented by corticosteroids. Hemolysis usually terminates spontaneously. Patients with secondary autoimmune hemolytic anemia may be treated similarly to those with idiopathic autoimmune hemolytic anemia, and additional therapy for the underlying disorder also may result in remission of the hemolysis.

Abstract
Patients receiving chronic steroids have an increased susceptibility to many different types of infections. The risk of infection is related to the dose of steroid and the duration of therapy. Although pyogenic bacteria are the most common pathogens, chronic steroid use increases the risk of infection with intracellular pathogens such as Listeria, many fungi, the herpes viruses, and certain parasites. Clinicians should consider both common and unusual opportunistic infections in patients receiving chronic steroids.

Abstract
Although dermatology now has the most extensive group of systemic medications available for the treatment of skin diseases at any time, GCSs remain the most important agents for managing inflammatory disorders. It is important that the dermatologist have a broad knowledge of guidelines for clinical use, pharmacology, and adverse effects of these drugs. Acute and chronic side reactions should be well recognized. An understanding of the HPA axis and reasons for administering GCSs in different ways is of great value. A good medical history should be taken on any patient treated with GCSs, including knowledge of conditions that would make GCSs inadvisable and other concomitant systemic medications that might produce drug interactions. During the course of therapy, physical examination should include all systems pertinent to side effects caused by these agents, including frequent evaluations of weight and blood pressure. Blood chemistries should be performed on a regular basis, including glucose, electrolytes, and serum lipids. Osteoporosis is one of the most significant adverse affects to be evaluated, with bone mineral density studies recommended on an annual basis for persons continuing on GCS therapy. If hip or other joint pain develops, MR imaging is the most specific and sensitive radiologic examination for evaluating the possibility of osteonecrosis. An ophthalmology examination should be performed every 6 to 12 months to detect early cataract or glaucoma development. Any early signs of infection should be evaluated by appropriate smears, wet preparations, and cultures. Many other studies, including gastrointestinal and pulmonary examinations, may be dictated by specific acute situations. It is important to begin early prevention of the bone loss that occurs with GCS-induced osteoporosis. The 1996 guidelines of the American College of Rheumatology, including adequate calcium and vitamin D intake, should be followed. Hormonal replacement, a bisphosphonate, calcitonin, or a thiazide diuretic may be indicated. Restriction of sodium in the diet is important, as well as adequate potassium intake. The diet should be low in saturated fat and calories and should be high in vegetable protein. Because osteoporosis is so prevalent with GCSs, keeping the patient as active as possible with mild-to-moderate exercise is important. Whenever possible, exposure to persons with infectious processes should be avoided, and proper treatment should be instituted at the initial signs of systemic or cutaneous infection. Oral doses of GCSs are best taken with food to prevent gastrointestinal irritation, and agents for gastric acidity occasionally may be indicated. Significant trauma should be prevented, as should severe exposure to the sun. Many situations may call for consultation with other medical or surgical subspecialists. The patient must be aware of the importance of regular physician evaluations and reporting of any adverse effects while on long-term GCSs. A good relationship and understanding between the patient and physician are vital in minimizing potential problems from these agents. If the dermatologist maintains the proper guidelines of care, patients on GCSs have the highest benefits and lowest risks possible.

Abstract
BACKGROUND One of the most probable pathogeneses of vitiligo is autoimmunity. Systemic corticosteroids suppress immunity and may arrest the progression of vitiligo and lead to repigmentation. The clinical efficacy of low-dose oral corticosteroids was assessed to minimize the side-effects in actively spreading vitiligo patients. METHODS Eighty-one patients with vitiligo were evaluated. The patients took daily doses of oral prednisolone (0.3 mg/kg body weight) initially for 2 months; the dosage was then reduced to half of the initial dose for the third month and was halved again for the fourth and final month. The effects of treatment were evaluated using photographs of before and after the study. Side-effects were assessed at the first, second, third and fourth month of treatment. RESULTS Arrested progression of vitiligo and repigmentation were noted in 87.7% and 70.4% of patients respectively. Male sex, a patient age of 15 years or under, and a duration of disease of 2 years or less showed increased repigmentation with statistical significance. The side-effects of treatment were minimal and did not affect the course of treatment. CONCLUSIONS Low-dose oral corticosteroids are effective without serious side-effects in preventing the progression and inducing repigmentation of actively spreading vitiligo, which is difficult to treat with topical corticosteroids or photochemotherapy.
