RESUMEN

The artery of Percheron (AOP) is an anatomical variant of the thalamoperforating arteries. AOP occlusion can cause bilateral paramedian thalamic infarctions and is referred to as a "stroke chameleon" because it lacks the classic signs of stroke. Coexistence of AOP occlusion and other neurologic disease is rare and can cause disturbance of consciousness. A 78-year-old woman had acute onset of left limb weakness and drowsy consciousness. Brain magnetic resonance angiography (MRA) revealed acute bilateral paramedian thalamic infarctions. However, serum and cerebrospinal fluid (CSF) cryptococcal antigen titers were 1:16 and 1:128, respectively. The CSF culture grew Cryptococcus neoformans. Although consciousness and muscle power improved after treatment, the patient later died of pneumonia. A 68-year-old woman developed acute disturbance of consciousness followed by delirium. Brain MRA revealed acute bilateral paramedian thalamic infarctions. Elevated free thyroxine, anti-thyroperoxidase, and anti-thyroglobulin antibodies were detected. She received 3 days of steroid pulse therapy followed by oral prednisolone. Her consciousness gradually improved after Hashimoto encephalopathy and stroke were controlled. AOP occlusion was diagnosed early in these two patients. However, other concomitant life-threatening diseases could have been overlooked because of the complicated diagnostic determination. Further serum cryptococcal antigen, anti-TPO Ab, and anti-TG Ab surveys might help to exclude cryptococcal meningitis and Hashimoto encephalopathy. CSF study is warranted when central nervous system infection is strongly suspected. This "Percheron artery-plus syndrome" comprises multifaceted disorders beyond the stroke chameleon and requires attention.

RESUMEN

BACKGROUND: The treatment of pemphigus is based on systemic corticosteroid use and adjuvant therapies, but some patients are resistant to conventional therapy. Tirabrutinib is a highly selective oral Bruton's tyrosine kinase inhibitor that may be clinically effective in treating pemphigus by suppressing B-cell signaling. OBJECTIVE: We investigated the efficacy and safety of tirabrutinib in patients with refractory pemphigus. METHODS: This was a multicenter, open-label, single-arm phase 2 study of Japanese patients with refractory pemphigus receiving appropriate treatment with an oral corticosteroid and adjuvant therapies. Patients received postprandial oral tirabrutinib 80 mg once daily for 52 weeks. After 16 weeks of tirabrutinib treatment, the corticosteroid dose was tapered to ≤10 mg/day of prednisolone equivalent. RESULTS: In total, 16 patients were evaluated (mean age, 52.5 years; 50 % male). The complete remission rate after 24 weeks of treatment (primary endpoint) was 18.8 % (3/16; 95 % confidence interval, 6.6 %-43.0 %). By Week 52, eight patients (50.0 %) achieved complete remission and 10 patients (62.5 %) achieved remission. Over 52 weeks of treatment, the mean prednisolone dose decreased from 17.03 to 7.65 mg/day. Incidences of adverse events (AEs) and adverse drug reactions were 87.5 % and 43.8 %, respectively. A relationship with tirabrutinib was ruled out for all serious AEs and Grade ≥3 AEs. CONCLUSION: Treatment with tirabrutinib enabled remission and reduced oral corticosteroid exposure over time and did not result in any major safety concerns in patients with refractory pemphigus. Thus, oral tirabrutinib may be a new treatment option for patients with refractory pemphigus.

RESUMEN

Although prednisolone (PD) is used as an anti-arthritis drug due to its rapid and strong anti-inflammatory potential, its frequent and large dosing often brings about adverse effects. Therefore, targeting therapy has attracted increasing attention to overcome such adverse effects. In the present study, nanogels (NGs) composed of macromolecule-PD conjugates were developed as a novel targeting delivery system, and their anti-inflammatory potential was examined. Conjugates were prepared by carbodiimide coupling between glycyl-prednisolone (GP) and the natural anionic polysaccharides, alginic acid (AL) and hyaluronic acid (HA). NGs were produced by the evaporation of organic solvent from the conjugate solution. The obtained NGs, named AL-GP-NG and HA-GP-NG, respectively, were examined for particle characteristics, in vitro release, pharmacokinetics, and in vivo efficacy. Both NGs were several hundred nanometers in size, had negative zeta potentials, and several % (w/w) drug contents. They released PD gradually at pH 7.4 and 6. They exhibited fairly good retention in the systemic circulation. In the efficacy examination using rats with adjuvant-induced arthritis, both NGs showed the stronger and more prolonged suppression of paw inflammation than PD alone. These suggested that the present NGs should be possibly useful as anti-arthritis targeting therapeutic systems.

RESUMEN

BACKGROUND: Portal vein thrombosis (PVT) is a rare presentation in dogs with protein-losing enteropathy (PLE). Rivaroxaban, an oral, selective, direct factor Xa inhibitor, has not been reported to be administrated for canine PVT and the effect is unclear in dogs with PLE. CASE PRESENTATION: An 11-year-old Yorkshire Terrier presented with moderate ascites. The dog had severe hypoalbuminemia (1.2 g/dL), and a portal vein thrombus was confirmed on computed tomographic angiography (CTA). On endoscopic examination, it became apparent that the hypoalbuminemia was caused by PLE, which was consequent of lymphatic dilation and lymphoplasmacytic enteritis. Therefore, the dog was initially treated with oral administrations of spironolactone and clopidogrel, with dietary fat restriction. However, a follow-up CTA showed no changes in the ascites, thrombus, and portal vein to aorta (PV/Ao) ratio. Therefore, the dog was additionally prescribed rivaroxaban and low-dose prednisolone for the portal vein thrombus and hypoalbuminemia due to lymphoplasmacytic enteritis, respectively. Following the treatment, the PV/Ao ratio decreased because of a decrease in the thrombus and the ascites disappeared completely with an elevation of albumin concentration (1.9 g/dL). CONCLUSIONS: This case report demonstrated that oral administration of rivaroxaban combined with low-dose glucocorticoid was effective management for PVT in a dog with PLE.

RESUMEN

The outbreak of coronavirus disease 2019 (COVID-19) has involved more than 159 countries and more than 5 million people worldwide. A 40-year-old man with a history of rheumatoid arthritis treated with prednisolone, Disease-Modifying Anti-Rheumatic Drugs (DMARDs), and biologic agents was admitted with chief complaints of fever, chills, malaise, myalgia, and dyspnea. Chest computed tomography showed bilateral subsegmental atelectasis and diffuse ground-glass opacities in both lungs inducing the suspicion of COVID-19 infection. The oro-nasopharynx swab sample for COVID-19 polymerase chain reaction was positive. In addition to supportive care, lopinavir/ritonavir 400/100 mg twice daily and oseltamivir (75 mg) twice daily were started in combination with a starting dose of hydroxychloroquine (400 mg). The methotrexate dose was decreased, and the dose of prednisolone was increased to 30 mg for 10 days. Azathioprine and adalimumab were continued at previous doses. The use of biologic agents and DMARDs in rheumatic patients is a serious challenge in the COVID-19 pandemic. In conclusion, during the COVID-19 pandemic, due to the key roles of cytokines in the promotion of the disease, the rheumatic patients may benefit from continuing their previous treatment, which may have protective effects.

RESUMEN

BACKGROUND: Oral lichen planus (OLP) is a mucocutaneous autoimmune disease with T-cell mediation. Corticosteroids are considered as a first choice in OLP and should be used for a long period with a subsequent increase in dose since the disease has a chronic and recalcitrant nature. There have been efforts to use alternative therapies due to the Corticosteroid's side effects. Curcumin is a non-toxic natural product with different effects on various oral diseases. It demonstrates antioxidant, anti-inflammatory, antimicrobial, and anticarcinogenic activities. It seems that Curcumin can be used as a proper alternative for Corticosteroid treatments. To overcome limitations in the bioavailability of Curcumin, the therapeutic effect of oral Nano-Curcumin was evaluated for the first time. METHODS: Sixty OLP patients were included in this double-blinded randomized clinical trial. The patients were randomly divided into two groups and received either 'Nano-Curcumin 80 mg' or 'Prednisolone 10 mg' treatments for 1 month. The patients should take one capsule after having their breakfast. The VAS scale was used to analyze pain severity and burning sensation. To assess lesion size the Thongprasom scale was employed. Repeated measures and independent t-tests, as well as LSD paired-test, were used to analyze the data. RESULTS: Data from 57 patients were analyzed. The level of pain, burning sensation, and OLP lesions decreased in both groups of Curcumin and Prednisolone and no statistically significant difference was observed between the two groups. CONCLUSION: Despite many studies conducted to find an effective approach for managing OLP, the results have often been unsatisfactory. In comparison with previous studies, current results clarify the importance of Nano-Curcumin bioavailability in therapeutic effects. Pain VAS and lesion size were decreased with oral Curcumin. The results have shown that oral Curcumin can be used as an alternative therapy for OLP in patients with the contraindicated Corticosteroids or should be used with caution. Oral Curcumin can be used in preventing the recurrence of OLP lesions after the treatment and initial control. Moreover, the amount of Curcumin dose is more important than its use duration in improving OLP. TRIAL REGISTRATION: IRCT, IRCT20100101002950N5.

RESUMEN

There is a trend towards offering immunotherapy to women with unexplained reproductive failure based on abnormal Natural Killer (NK) cell levels. Previous systematic reviews evaluating immunotherapy usage have not focused on women with abnormal level of NK cells. To address the gap in literature, this systematic review aims to evaluate the efficacy of immunotherapy to improve pregnancy outcome in women with recurrent miscarriage (RM) or implantation failure (RIF) specifically selected based on abnormal levels and/or activity of NK cells. Six databases were searched for peer-reviewed studies following PRISMA guidelines. Risk of bias assessment was conducted using RoB2 for randomized controlled trials (RCT) and ROBINS-I for non-RCT. Of 1025 studies identified, seven studies on intravenous immunoglobulin (IVIG) (four), prednisolone (one), etanercept (one) and intralipid (one) were included. Meta-analysis of the non-RCT IVIG studies (557 participants; 312 intervention, 245 controls) showed livebirth in favour of intervention (RR 2.57; 95 % CI = 1.79-3.69; p < 0.05), however there were significant heterogeneity (I2 = 62 %) and moderate to severe risk of bias in these studies. Individual RCTs reported improved livebirth outcome in etanercept, intralipid and prednisolone and this was significant in the former two (p < 0.05). In conclusion, there may be some benefit of immunotherapy, but paucity of high quality evidence means that it is not possible to support the use of immunotherapy even when selected based on abnormal NK cell level/activity. Further research with application of scientifically validated immunological biomarkers in well-planned large scale RCTs will determine whether immunotherapy is beneficial in this subpopulation of women.

RESUMEN

Treatment of patients with the rare disease eosinophilic granulomatosis with polyangiitis (EGPA) with mepolizumab, a monoclonal antibody to interleukin-5 (IL-5) that reduces blood eosinophil counts, as an add-on therapy to glucocorticoid treatment, results in more accrued weeks in remission, reductions in glucocorticoid use and reductions in relapse rate. However, treatment response varies across a continuum. Therefore, to investigate if large genetic effects could identify responders, the impact of genetic variants on efficacy in EGPA subjects taking mepolizumab and glucocorticoids was assessed in this post hoc study. Using linear regression and a negative binomial model, genetic variant association with three endpoints (accrued duration of remission, average oral glucocorticoid dose, and frequency of relapse) was tested in 61 EGPA subjects dosed with mepolizumab from MIRRA, a phase 3 trial. Candidate gene and genome-wide approaches were used. The candidate gene analysis was designed to investigate drug target effects with eight gene regions selected that were focused on the intersection of the glucocorticoid response (steroidal response) and IL-5 response mechanisms and recognizing potential overlap between EGPA and severe eosinophilic asthma diseases for which mepolizumab is used. The sample size was insufficient to enable testing of rare variants for effects. No genetic variant from either the candidate gene analysis or the GWAS associated with any endpoint. Thresholds to declare significance were p < 0.0008 (candidate variant) and p < 2.5 × 10-8 (genome-wide) analyses. Large genetic effects on mepolizumab-treatment response were not identified which could help differentiate responders from non-responders.

RESUMEN

PURPOSE: To evaluate the effects of prednisolone against sodium diclofenac both with ciprofloxacin compared to artificial tears on the symptoms and signs of acute viral conjunctivitis. METHODS: Study included 37 patients diagnosed with acute conjunctivitis and distributed by three groups: A (1% prednisolone acetate + ciprofloxacin (0.3%); B (Sodium diclofenac (0.1%) + ciprofloxacin (0.3%) and C (artificial tears + ciprofloxacin (0.3%). Patients received medication 6/6 hours daily. Signs and symptoms (e.g. lacrimation, burning, photophobia, etc.) were scored at baseline and on the first, third, fifth and seventh days and in the end of treatment using a standardized questionnaire and slit lamp anterior segment examination. RESULTS: All three groups demonstrated an improvement in the signs and symptoms of conjunctivitis in their follow-up visits. There was no significant difference in symptom and sign scores between Group A and B and B and C in the study visits ( p >0.05). However, the comparison between groups A and C showed a clinical trend (p=0.05) on third evaluation suggesting better clinical action using the corticosteroids. CONCLUSION: The prednisolone acetate was not superior to the use of sodium diclofenac or artificial tears in relieving the signs and symptoms of viral conjunctivitis.

RESUMEN

PURPOSE: The efficacies of hyperbaric oxygen therapy (HBO), systemic steroid, prostaglandin E1, or the combination of any two modalities have been reported in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). However, little is known about the combined efficacy of HBO, systemic steroid, and prostaglandin E1 for this disorder. We aimed to investigate the efficacy of HBO combined with systemic steroids and prostaglandin E1 as triple therapy in patients with ISSNHL. MATERIALS AND METHODS: We retrospectively evaluated the records of 67 patients with ISSNHL who were treated with systemic steroid and prostaglandin E1, with (n = 38) or without (n = 29) HBO. The inclusion criteria included a diagnosis of ISSNHL within 14 days of symptom onset, age ≥15 years, treatment according to the protocol, and clinical follow-up of at least 1 month. The patients' hearing levels were evaluated 1 month after hearing loss onset. The primary outcome was hearing improvement on pure tone audiometry. We also evaluated the demographic profiles of patients. RESULTS: Patients treated with triple therapy showed significantly greater hearing improvement (p < 0.01) than those treated without HBO, despite some differences between the two treatment groups. Multivariate logistic regression analysis revealed a significant positive correlation between pure tone audiometry improvement and hyperbaric oxygen therapy, after adjustment for confounding factors (odds ratio = 7.42; 95% and confidence interval = 2.37-23.3; p = 0.001). CONCLUSION: HBO with systemic steroid and prostaglandin E1 administration conferred significant therapeutic benefits for ISSNHL. Therefore, routine use of triple therapy is recommended for patients with ISSNHL.

RESUMEN

BACKGROUND: Prednisolone (PD) is extremely effective for treating rheumatoid arthritis (RA). However, it distributes nonspecifically throughout the body and its use is associated with serious side effects, which promoted us to compound it into a phytomedicine for greater efficacy and safety. METHODS: We combined PD with curcumin (CU), an effective monomer from traditional Chinese medicine, and human serum albumin (HSA) in a nanoparticulate system (N-PD/CU) to compensate for the poor bioavailability of PD and CU. N-PD/CU was prepared by high-pressure homogenization, and its characteristics were evaluated in vitro. Next, we investigated its toxicity and mechanism of anti-inflammatory to macrophages. Finally, its pharmacokinetics, biodistribution and therapeutic efficacy were assessed in rats with adjuvant-induced arthritis (AIA). RESULTS: N-PD/CU showed a narrow size distribution around 150.4 ± 2.4 nm, a polydispersity index of 0.22 ± 0.02 and drug loading efficiency (DLE) of 88.75 ± 1.82% for PD and 85.79 ± 1.43% for CU. N-PD/CU showed sustained release of both drugs in vitro. N-PD/CU had no toxicity to macrophages in vitro on concentrations between 0.1 and 1.2 µmol/mL. In activated macrophages, N-PD decreased levels of pro-inflammatory cytokines, while N-CU increased levels of anti-inflammatory IL-10, and N-PD/CU exhibited best therapeutic effect in vitro, suggesting co-delivery of PD and CU may synergistically control the course of RA. In AIA rats, N-PD/CU accumulated in inflamed joints through the effect of extravasation through leaky vasculature and subsequent inflammatory cell-mediated sequestration (ELVIS effect) in inflammatory lesion and showed higher therapeutic efficacy than single-loaded nanoparticles, either free drug on its own, or a simple mixture of the two drugs. CONCLUSION: This codelivery system based on HSA is a promising platform for combination chemotherapy in RA.

RESUMEN

OBJECTIVE: To determine whether extending initial prednisolone treatment from eight to 16 weeks in children with idiopathic steroid sensitive nephrotic syndrome improves the pattern of disease relapse. DESIGN: Double blind, parallel group, phase III randomised placebo controlled trial, including a cost effectiveness analysis. SETTING: 125 UK National Health Service district general hospitals and tertiary paediatric nephrology centres. PARTICIPANTS: 237 children aged 1-14 years with a first episode of steroid sensitive nephrotic syndrome. INTERVENTIONS: Children were randomised to receive an extended 16 week course of prednisolone (total dose 3150 mg/m2) or a standard eight week course of prednisolone (total dose 2240 mg/m2). The drug was supplied as 5 mg tablets alongside matching placebo so that participants in both groups received the same number of tablets at any time point in the study. A minimisation algorithm ensured balanced treatment allocation by ethnicity (South Asian, white, or other) and age (5 years or less, 6 years or more). MAIN OUTCOME MEASURES: The primary outcome measure was time to first relapse over a minimum follow-up of 24 months. Secondary outcome measures were relapse rate, incidence of frequently relapsing nephrotic syndrome and steroid dependent nephrotic syndrome, use of alternative immunosuppressive treatment, rates of adverse events, behavioural change using the Achenbach child behaviour checklist, quality adjusted life years, and cost effectiveness from a healthcare perspective. Analysis was by intention to treat. RESULTS: No significant difference was found in time to first relapse (hazard ratio 0.87, 95% confidence interval 0.65 to 1.17, log rank P=0.28) or in the incidence of frequently relapsing nephrotic syndrome (extended course 60/114 (53%) v standard course 55/109 (50%), P=0.75), steroid dependent nephrotic syndrome (48/114 (42%) v 48/109 (44%), P=0.77), or requirement for alternative immunosuppressive treatment (62/114 (54%) v 61/109 (56%), P=0.81). Total prednisolone dose after completion of the trial drug was 6674 mg for the extended course versus 5475 mg for the standard course (P=0.07). There were no statistically significant differences in serious adverse event rates (extended course 19/114 (17%) v standard course 27/109 (25%), P=0.13) or adverse event rates, with the exception of behaviour, which was poorer in the standard course group. Scores on the Achenbach child behaviour checklist did not, however, differ. Extended course treatment was associated with a mean increase in generic quality of life (0.0162 additional quality adjusted life years, 95% confidence interval -0.005 to 0.037) and cost savings (difference -£1673 ($2160; €1930), 95% confidence interval -£3455 to £109). CONCLUSIONS: Clinical outcomes did not improve when the initial course of prednisolone treatment was extended from eight to 16 weeks in UK children with steroid sensitive nephrotic syndrome. However, evidence was found of a short term health economic benefit through reduced resource use and increased quality of life. TRIAL REGISTRATION: ISRCTN16645249; EudraCT 2010-022489-29.

RESUMEN

PURPOSE: This investigation was aimed to explore the targeting potential of folate conjugated double liposomes (fDLs) bearing combination of synergistic drugs (Prednisolone and Methotrexate) for effective management of the rheumatoid arthritis (RA). METHODS: To overcome the drawbacks of monotherapy, a combination of prednisolone (PRD) (an anti-inflammatory agent) and methotrexate (MTX) (a disease modifying anti-rheumatoid agent, DMARDs) was chosen for dual targeting approach. fDLs were prepared in two steps i.e. development of inner liposomes (ILs) using thin film casting method followed by encapsulation of ILs within folate conjugated outer liposomes (double liposomes; fDLs). Developed liposomes were characterized for various physicochemical parameters and in vivo performance. RESULTS: fDLs were prepared using FA-PEG-4000-NH-DSPE conjugate. These double liposomes were having 429.3 ± 3.6 nm in size with 0.109 PDI, 8.01 ± 0.3 mV zeta potential (ζ) and 66.7 ± 3.9% and 45.3 ± 1.7% entrapments of PRD and MTX, respectively. After 24 h, the concentrations of PRD in blood were observed to be 8.66 ± 3.11 (ILs) and 15.13 ± 0.81% (DLs) while concentration of MTX were found to be 10.89 ± 0.69 and 2.34 ± 3.15% when given as ILs and fDLs, respectively. The concentration of both drugs in inflamed joint was observed to be higher than that in the non-inflamed joints. CONCLUSIONS: The folate conjugated double liposomes possess superior targeting efficiency than conjugated and unconjugated single liposomes.

RESUMEN

An eighty-nine-year-old Japanese male was admitted to our hospital due to dry cough and dyspnea. Respiratory symptoms appeared soon after an administration of an oriental medicine, Kamikihito for tinnitus. Upon admission, chest computed tomography showed patchy consolidations and ground-glass opacities in the right upper lobe of the lungs, and ground-glass opacities in the bilateral lower lobes. Sulbactam-ampicillin combination (SBT/ABPC, 3 g × 2/day) was started in addition to the change or cessation of several other drugs, including Kamikihito, resulting in respiratory symptoms and chest radiographic exacerbations. Bronchoalveolar lavage fluid obtained from the right S3 showed an increase in the total cell number of lymphocytes. A drug lymphocyte stimulation test (DLST) for Kamikihito was also positive. Kamikihito-induced lung injury was most likely, and treatment with prednisolone (50 mg/day) was started. His respiratory symptoms and chest radiographic findings improved rapidly soon after initiating oral prednisolone. This is the first report of Kamikihito-induced lung injury.

RESUMEN

Autoimmune hepatitis is a corticosteroid-responsive liver disease arising consequent to immunogenetic and environmental risk factors. The clinical course reflects relapsing and remitting, hepatocyte targeted immunologic damage, which is countered by reparative responses to cell injury. Appropriate and timely immunosuppressive therapy drives the disease into remission, albeit with inevitable side effects. Many challenges faced in the clinic reflect practice that must capture a heterogeneous disease presentation, course, and treatment response, as well as treatment tolerability. In this Grand Round we appraise the evidence supporting current treatment approaches, address the impact of autoimmune liver disease 'crossover or overlap' presentations, explore important clinical correlates to immune-serological classifiers, and discuss the factors influencing choice of alternative therapy in difficult-to-treat situations.

RESUMEN

Vitamin D has been demonstrated to have an immunomodulatory role in cystic fibrosis with allergic bronchopulmonary aspergillosis (ABPA). Herein, we evaluate supplemental vitamin D in acute-stage ABPA complicating asthma. Thirty subjects were randomised to receive either prednisolone (n = 15, control) or prednisolone and oral vitamin D (n = 15, intervention arm). Serum vitamin D levels were significantly higher in the intervention versus the control arm, following therapy. The mean decline in total IgE at 2 months (primary outcome) was 10% higher in the intervention arm than the control arm; however, this was not statistically significant (48.6% vs 38.1%, P = 0.27). The percentage decline in total IgE after 4 and 6 months of randomisation was also similar in the two arms. There was no difference in asthma exacerbations (0 vs 2, intervention vs control; P = 0.16). No ABPA exacerbation occurred in either arm. The other outcomes including the Th2 (IL-4, IL-6 and IL-10) and Th17 (IL-17) cytokine levels were similar in the two groups. None of the participants experienced hypervitaminosis D. There was no significant improvement in the clinical or immunological outcomes following vitamin D supplementation. A larger trial is required to ascertain the role of vitamin D in ABPA complicating asthma [Clinicaltrials.gov: NCT03133299].

RESUMEN

Abstract Purpose To evaluate the effects of prednisolone against sodium diclofenac both with ciprofloxacin compared to artificial tears on the symptoms and signs of acute viral conjunctivitis. Methods Study included 37 patients diagnosed with acute conjunctivitis and distributed by three groups: A (1% prednisolone acetate + ciprofloxacin (0.3%); B (Sodium diclofenac (0.1%) + ciprofloxacin (0.3%) and C (artificial tears + ciprofloxacin (0.3%). Patients received medication 6/6 hours daily. Signs and symptoms (e.g. lacrimation, burning, photophobia, etc.) were scored at baseline and on the first, third, fifth and seventh days and in the end of treatment using a standardized questionnaire and slit lamp anterior segment examination. Results All three groups demonstrated an improvement in the signs and symptoms of conjunctivitis in their follow-up visits. There was no significant difference in symptom and sign scores between Group A and B and B and C in the study visits ( p >0.05). However, the comparison between groups A and C showed a clinical trend (p=0.05) on third evaluation suggesting better clinical action using the corticosteroids. Conclusion The prednisolone acetate was not superior to the use of sodium diclofenac or artificial tears in relieving the signs and symptoms of viral conjunctivitis.

RESUMEN

INTRODUCTION: Alcohol-induced intestinal dysbiosis is central to the development of the severe alcoholic liver disease. We present the first study to compare outcomes in patients of severe alcoholic hepatitis (SAH) on nutritional therapy, corticosteroids, pentoxifylline, and healthy donor fecal transplantation (FMT) and discuss distinct microbial community and microbiome metabolic functional changes after FMT. METHODS: Out of 1271 liver disease patients, 809 (63.7%) were diagnosed to have the alcoholic liver disease, of which 51 patients (8 treated with corticosteroids, 17 with nutritional support only, 10 with pentoxifylline, 16 receiving FMT) were included. Clinical, biochemical parameters, liver disease, and alcoholic hepatitis severity scores at baseline and mortality at the end of 1 and 3 months were analyzed between groups. Stool microbiota (SM) analysis was performed for healthy controls (HC) and respective recipients after FMT. RESULTS: All the patients were male. The proportions of patients surviving at the end of 1 and 3 months in the steroids, nutrition, pentoxifylline, and FMT group were 63%, 47%, 40% and 75% [p = 0.179] and 38%, 29%, 30%, and 75% [p = 0.036], respectively. When compared with FMT, relative risk and hazard ratios for death were higher in all the other groups. Following FMT, distinct and beneficial modulation of SM and pathways of dysregulated metabolism, infections, inflammation, and oxidative stress in SAH patients were noted in tandem with improved clinical outcomes. CONCLUSIONS: Healthy donor FMT for SAH improves survival beyond what is offered by current therapies and can function as a cost-effective bridge to liver transplant (LT) or for improving transplant-free survival. Larger studies and randomized trials are unmet needs.

RESUMEN

BACKGROUND: The use of glucocorticoids in various forms of administration is complicated by their systemic side effects. Although intravenous pulse therapy is considered to have lesser systemic side effects, there are few studies in literature comparing the effects of intravenous pulse glucocorticoids versus oral daily glucocorticoids on bone mineral density. AIM: To compare the effects of intravenous pulse glucocorticoids and oral daily glucocorticoids on bone mineral density with the aim of finding any site-specific osteopenic side effect. METHODS: The study was conducted by the department of dermatology of Postgraduate Institute of Medical Education and Research, Chandigarh, India. The study comprised of two groups of patients. Group A consisted of 28 patients with pemphigus vulgaris who received intravenous pulses of dexamethasone at 4 weekly intervals. Group B consisted of 21 patients with airborne contact dermatitis who received oral daily prednisolone therapy. All the patients had a dual X-ray absorptiometry scan at baseline, and at 3 and 6 months of follow-up. The results were analyzed as changes in bone mineral density. RESULTS: There was loss of bone mineral density at lumbar spine and the head of radius in both the groups. At the lumbar spine, Group B showed more reduction in bone mineral density at 3 months whereas in Group A it was more at the head of radius. In patients on oral steroids, the lumbar spine was significantly more affected than the head of radius at both 3 and 6 months of follow-up. However, in patients on intravenous pulse steroids, both the sites were equally affected at 3 and 6 months. LIMITATIONS: In our study, we used different glucocorticoids in the two groups: prednisolone in the oral daily group and dexamethasone in the intravenous pulse steroids group. A similar reduction in bone mineral density in both the groups may have been due to a longer half-life or more bone-directed side effects of dexamethasone as compared to prednisolone. CONCLUSION: Dermatologists need to be aware of the detrimental effects of high-dose intravenous pulsed glucocorticoids on bone mineral density and assessment of this parameter should be done before the initiation of therapy and also at regular intervals thereafter. During follow up, either the lumbar spine or the head of radius can be used to assess the osteopenic effect of intravenous pulse steroids, whereas the lumbar spine is a better site for this evaluation in patients on oral steroids.
