Awareness Regarding Corticosteroids use and Side Effects among Patients and Irrational Users in Gadarif, Sudan: A Cross-Sectional Study

Background: Corticosteroids are widely used medications essential for managing various autoimmune, allergic, and inflammatory conditions. However, their misuse and prolonged use can lead to significant adverse effects, necessitating careful considerations and proper use. Aims and Objectives: To assess the awareness of corticosteroid use and side effects among patients and those using them irrationally, to explore behaviors related to their use, and to identify and report associated side effects. Materials and Methods: A structured questionnaire was administered through interviews to collect data from a total of 300 participants. The data collection was conducted by a team of well-trained assistant researchers at Gadarif Teaching Hospital, Outpatient clinics, and cosmetic shops where steroidal products are sold. Data analysis was performed using SPSS version 27, employing standard descriptive and analytical statistics, While POWER BI was utilized for data visualization. Results: The study found that misuse of corticosteroid was prevalent, and only (21.0%) of participants demonstrating adequate awareness of their side effects. There was a week positive correlation between education level and awareness. Conclusion: Enhanced education and increased awareness of the appropriate use of corticosteroids, along with vigilance for potential side effects, are crucial to optimizing patient safety and outcomes.

Risks and benefits of anti-TNF therapy for ulcerative colitis in a patient with autoimmune hepatitis-related cirrhosis: Case report.

Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) characterized by continuous inflammation of the colonic mucosa. Autoimmune hepatitis (AIH) is a chronic liver disease characterized by hypergammaglobulinemia, circulating autoantibodies, interface hepatitis, and favorable response to immunosuppression. An association between IBD and AIH is uncommon, and experts have suggested that in patients with overlapping IBD and AIH, the anti-tumor necrosis factor agents can be used. Therefore, this study reports a rare case of a patient with liver cirrhosis due to AIH and UC refractory to conventional treatment and discusses the risks and benefits of using anti-tumor necrosis factor in both conditions. A 28-year-old female presented with symptoms of diarrhea, abdominal pain, asthenia, and inappetence, accompanied by abdominal collateral circulation, anemia, alteration of liver enzymes, and elevation of C-reactive protein levels. The patient underwent a liver biopsy, which was consistent with liver cirrhosis due to AIH. Colonoscopy showed an inflammatory process throughout the colon, compatible with moderately active UC. The patient received mesalazine, azathioprine, and corticotherapy, with no control of the inflammatory process. Faced with refractoriness to drug treatment and side effects of corticosteroids with an increased risk of severe infection due to cirrhosis, we opted to use infliximab for the treatment of UC. The patient presented with a clinical response and infliximab therapy was maintained. Eight months after starting infliximab therapy, the patient developed pneumonia with complications from disseminated intravascular coagulation and died. AIH is a rare cause of elevated transaminase levels in patients with UC. The best treatment to control the 2 conditions should be evaluated with vigilance for the side effects of medications, mainly infections, especially in patients with cirrhosis.

Cardiac sarcoidosis treated with nonsteroidal immunosuppressive therapy

BackgroundNonsteroidal immunosuppressive therapy is a potential therapeutic strategy for cardiac sarcoidosis. However, it is not recommended as an established treatment option. This study aimed to demonstrate the clinical outcomes of patients with cardiac sarcoidosis using nonsteroidal immunosuppressants through the ILLUstration of the Management and PrognosIs of JapaNese PATiEnts with Cardiac Sarcoidosis multicenter retrospective registry. MethodsFrom a cohort of 512 patients, 426 who received corticosteroid therapy and 26 who received other immunosuppressive therapy were included for analysis. Clinical outcomes included all-cause death, fatal ventricular arrhythmic events (FVAE), and worsening heart failure with hospitalization. ResultsNonsteroidal immunosuppressants were used for retained fluorodeoxyglucose uptake in the heart (n = 14), corticosteroid side effects (n = 7), ventricular arrhythmia (n = 4), complete atrioventricular block (n = 2), worsened extracardiac sarcoidosis (n = 2), and other reasons (n = 2). They comprised of methotrexate (n = 20), cyclosporine (n = 2), cyclophosphamide (n = 2), and azathioprine (n = 3). After the addition of a nonsteroidal immunosuppressant, corticosteroids were reduced in 14 of 26 patients (5 [5–17] mg), although no patient discontinued corticosteroids. Of the 14 patients, decreased fluorodeoxyglucose uptake was observed in seven at follow-up. Clinical outcomes were observed in 11 patients (42.3 %). Detected events included all-cause death in five patients (19.2 %), FVAE in four (15.4 %), and worsening heart failure with hospitalization in five (19.2 %), with some overlap. ConclusionsNonsteroidal immunosuppressive therapy may be a possible treatment option for patients who are not stabilized with corticosteroids alone or develop corticosteroid side effects.

Strategic Approaches in Formulation Development for Atopic Dermatitis

Atopic dermatitis (AD) is the most common chronic skin disease, significantly impacting patients’ quality of life. One of the most effective management approaches for AD involves addressing the defective skin barrier by urging AD patients to regularly use suitable moisturizers. Therapeutic moisturizers designed for AD are precisely formulated with ingredients targeting critical and often early symptoms of AD (e.g., itch, inflammation, damaged skin barrier). Dermo-cosmetic products, which are rich in moisturizing and emollient agents contributing to recovery as well as strengthening the skin barrier, have proven to be excellent adjuncts in AD treatment. There are various galenic forms of dermo-cosmetics, such as lotions, gels, creams, foams, and sprays, requiring a rationale in choosing ingredients for the product formulation and development. In addition, the role of moisturizer and emollient therapy to address skin dryness linked to dermatological conditions is hugely dependent on varying chemistry and morphology in the deeper regions of the skin. There are also limits to the efficacy of treatments, corticosteroid side effects, and product sensory appeal, which may decrease patient acceptance and compliance. The objective of this review is thus to offer a comprehensive overview of the critical aspects involved in the development of cosmetic vehicles, as well as a detailed examination of the primary ingredients used in formulations for AD.

Pulse methylprednisolone therapy triggered sinus bradycardia in two children

Intravenous methylprednisolone is an important therapeutic modality in many conditions, owing to their anti-inflammatory and immune-modulating properties. Along with other side-effects of corticosteroids, cardiovascular side-effects are also seen in varying degree in children. Sinus bradycardia is reported uncommonly in children following high dose intravenous methylprednisolone. We report two paediatric cases without any underlying cardiac problems with asymptomatic bradycardia following high dose intravenous methylprednisolone. Heart rate reduction was seen from 30-40% compared to the baseline heart rate, which returned to its normal value after 24-36 hours of stoppage of the offending drug. A high index of suspicion along with strict cardiovascular monitoring is necessary in patients receiving high dose of methylprednisolone.

Awareness of Side Effects of Corticosteroids among Users and Nonusers in Saudi Arabia

ABSTRACT Background: Corticosteroids are anti-inflammatory medications that are used to reduce inflammation and inhibit the immune system in a variety of disorders, including allergies, asthma, systemic lupus erythematous, eczema, inflammatory bowel disease, and swollen joints or muscles. The goal of this study was to assess the level of awareness and sources of information about the side effects of corticosteroids among the general population in Saudi Arabia. Methods: This observational cross-sectional study was conducted in Saudi Arabia using an electronic questionnaire. A non-probability convenience sampling technique was used. Statistical Package for the Social Sciences (SPSS) was used for data analysis. Results: The study included 755 participants from Saudi Arabia (67.3% females and 32.7% males). Around 26.8% reported using corticosteroids, and 73.9% were aware of the side effects of glucocorticoids. Among steroid users (202 participants), the most common conditions were allergies (36.1%), asthma or chronic obstructive pulmonary disease (COPD) (21.8%), and skin diseases (27.7%). The majority of respondents (57.9%) used steroids for less than 2 weeks, and topical application (52.5%) was the most common form. Only 30.7% received information about side effects at the time of prescription. The most reported side effects were truncal obesity, moon face, skin thinning, bruising, and slower wound healing. Conclusion: This study highlights the importance of promoting awareness and knowledge regarding the side effects of corticosteroids in Saudi Arabia. While overall awareness levels were relatively satisfactory, specific side effects require further attention in educational efforts.

A Comparative Study of Intra-Articular Knee Injection of Leukocyte-Poor Platelet-Rich Plasma Compared to Corticosteroids and Local Anesthetics in Patients with Knee Osteoarthritis

Background: Knee osteoarthritis (OA) is the most common reason for orthopedic secondary care referral. And it is one of the main causes of disability in adults worldwide. It is estimated to affect between 10 to 25% of patients over the age of 60. Intra-articular corticosteroid injection (IA CS) and physical therapy were the two choices in an attempt to provide symptomatic management or deferred surgery. There is a growing trend is intra-articular platelet-rich plasma (IA PRP) injection to reduce pain and improve function in OA patients. PRP is divided into two types: leukocyte-poor platelet-rich plasma (LP-PRP) and leukocyte-rich platelet-rich plasma (LR-PRP). It was shown that LR-PRP increases pro-inflammatory factors and also decreases anti-catabolic mediators, and LP-PRP has the opposite aspect.
 Methods: In our research 40 patients were divided into two equal groups, IA corticosteroid and leukocyte-poor platelet-rich plasma (LP-PRP) 40 cc of blood from the basilic vein of the upper limb is used with two step centrifugation. The final samples were 4 millilitres product injected intra-articular. group two (corticosteroid (CS)) received an intra-articular injection of triamcinolone acetate (Kenalog) 40 mg/ml along with 4 ml of lidocaine 0.02% (Abureyhan Co.) for a total of 5 ml. The needle used is a 22-gauge pencil-point Quincke needle (Dr. Japan Co, Ltd), which is performed with the Sonosite Edge II ultrasound guide and in an anterior-lateral manner in the knee joint. Pain was assessed on a visual analogue scale (VAS range 0-10 points) before, one week, one month, two month and 3 months after the operation. The WOMAC questionnaire was also filled before injection and three months following injection and other variables were examined.
 Results: There were no significant differences between the groups across all the baseline parameters including age, sex, body mass index and comorbidities including high blood pressure, diabetes and smoking. Both injection groups were effective in reducing patients' pain from one week to three months after injection. The level of pain in the first week after injection was significantly lower in the corticosteroid group than in the PRP group. In the first month and the third month after the injection, the pain reduction according to mean scores of VAS was the same in both groups.
 Conclusion: In short, one injection of PRP can reduce the pain of patients with osteoarthritis of the knee as much as corticosteroids during a three-month treatment process. Considering the possible side effects of corticosteroids, this alternative treatment can be considered with further investigation.

A Case Series of Idiopathic Granulomatous Mastitis: Surgical Intervention is not the Only Option

Idiopathic Granulomatous Mastitis (IGM) is a benign inflammatory disease of the breast that is difficult to treat, as there is no definitive protocol for management and it has a higher recurrence rate. The present case series presents five patients who exhibited clinical symptoms such as breast swelling, pain and nipple discharge, and were diagnosed with IGM. They were treated with a multimodality approach (surgical and/or conservative management) based on their symptoms. All patients were successfully treated for IGM using the multimodality approach. While a recurrence was observed in one out of five patients, it was further successfully treated with additional conservative management. The proposed multimodality treatment is effective in treating IGM. It eliminates the risk associated with surgical intervention among patients clinically diagnosed with IGM. It also eliminates the risk of corticosteroid side-effects among patients whose initial clinical diagnosis and postoperative histopathological examination is negative for IGM.

Optimizing Neurocysticercosis Care: Pharmacotherapy, Surgery, and Monitoring

Neurocysticercosis, caused by Taenia solium larval invasion of the central nervous system, demands a nuanced approach. Treatment involves corticosteroids (dexamethasone, prednisolone, prednisone) and antiparasitic agents (albendazole, praziquantel), tailored to lesion characteristics. Surgical interventions may be necessary. Pregnancy requires anthelmintic therapy deferment. Vigilant monitoring, weaning off antiepileptics, and managing corticosteroid side effects are crucial. This concise overview navigates the intricate landscape of neurocysticercosis management for optimal patient outcomes.

Intralesional or intraorbital rituximab injection for the management of biopsy-proven idiopathic orbital inflammation involving the lacrimal gland

ObjectifMesurer l'efficacité de l'injection intralésionnelle de rituximab dans la prise en charge de l'inflammation orbitaire idiopathique (IOI) touchant la glande lacrymale, soit le sous-type le plus fréquent. MéthodeOn a inclus 18 patients consécutifs qui présentaient une IOI touchant la glande lacrymale objectivée par biopsie et auxquels on a administré le rituximab (50 mg/5 mL) directement dans la lésion une fois par mois. RésultatsDu point de vue clinique, tous les patients présentaient un œdème et une ptose de la paupière supérieure. La plupart d'entre eux (56 %) avaient en outre une douleur périoculaire et une masse supéro-temporale palpable. Les biopsies ont fait ressortir une inflammation chronique sans fibrose chez 14 patients (78 %) et une inflammation chronique s'accompagnant de fibrose chez 4 patients (22 %). Ainsi, 1 patient (6 %) a reçu une seule dose de rituximab par voie intralésionnelle parce qu'il a bénéficié d'une réponse complète après la première injection; 11 patients (61 %) ont reçu 2 doses tandis que 6 patients (33 %) ont reçu 3 doses en raison d'une réponse partielle après les 2 premières injections. Après un suivi moyen de 33 mois (médiane : 33 mois; fourchette : 11–59 mois), 16 patients (89 %) ont eu une réponse clinique, dont 14 patients (78 %) chez lesquels la réponse était complète (soit la disparition de toutes les lésions) et 2 patients (11 %) chez lesquels la réponse était partielle (soit une diminution de ≤ 30 % du diamètre de la lésion). Par ailleurs, 2 patients (11 %) n'ont eu aucune réponse après 3 injections et ont dû entreprendre un traitement par voie générale associant un corticostéroïde et le méthotrexate. Enfin, 2 des patients (11 %) qui avaient eu une réponse complète ont subi une récurrence 12 et 49 mois après la dernière injection. Ces 2 patients ont reçu 2 doses supplémentaires de rituximab, espacées de 1 mois, et affichaient une réponse complète lors de l'examen de suivi 27 et 11 mois après le traitement, respectivement. ConclusionL'injection intralésionnelle de rituximab peut constituer un traitement efficace de l'IOI touchant la glande lacrymale, le taux de réponse complète ayant atteint 78 % dans notre série de cas. L'administration locale de rituximab permet d’éviter les éventuels effets indésirables oculaires et systémiques typiques des corticostéroïdes et des immunosuppresseurs administrés par voie générale.

Anti-inflammatory reprogramming of microglia cells by metabolic modulators to counteract neurodegeneration; a new role for Ranolazine

Microglia chronic activation is a hallmark of several neurodegenerative diseases, including the retinal ones, possibly contributing to their etiopathogenesis. However, some microglia sub-populations have anti-inflammatory and neuroprotective functions, thus making arduous deciphering the role of these cells in neurodegeneration. Since it has been proposed that functionally different microglia subsets also rely on different metabolic routes, we hypothesized that modulating microglia metabolism might be a tool to enhance their anti-inflammatory features. This would have a preventive and therapeutic potential in counteracting neurodegenerative diseases. For this purpose, we tested various molecules known to act on cell metabolism, and we revealed the anti-inflammatory effect of the FDA-approved piperazine derivative Ranolazine on microglia cells, while confirming the one of the flavonoids Quercetin and Naringenin, both in vitro and in vivo. We also demonstrated the synergistic anti-inflammatory effect of Quercetin and Idebenone, and the ability of Ranolazine, Quercetin and Naringenin to counteract the neurotoxic effect of LPS-activated microglia on 661W neuronal cells. Overall, these data suggest that using the selected molecules -also in combination therapies- might represent a valuable approach to reduce inflammation and neurodegeneration while avoiding long term side effects of corticosteroids.

Intratracheal budesonide mixed with surfactant to increase survival free of bronchopulmonary dysplasia in extremely preterm infants: statistical analysis plan for the international, multicenter, randomized PLUSS trial

BackgroundBronchopulmonary dysplasia (BPD), an inflammatory-mediated chronic lung disease, is common in extremely preterm infants born before 28 weeks’ gestation and is associated with an increased risk of adverse neurodevelopmental and respiratory outcomes in childhood. Effective and safe prophylactic therapies for BPD are urgently required. Systemic corticosteroids reduce rates of BPD in the short term but are associated with poorer neurodevelopmental outcomes if given to ventilated infants in the first week after birth. Intratracheal administration of corticosteroid admixed with exogenous surfactant could overcome these concerns by minimizing systemic sequelae. Several small, randomized trials have found intratracheal budesonide in a surfactant vehicle to be a promising therapy to increase survival free of BPD. The primary objective of the PLUSS trial is to determine whether intratracheal budesonide mixed with surfactant increases survival free of bronchopulmonary dysplasia (BPD) at 36 weeks’ postmenstrual age (PMA) in extremely preterm infants born before 28 weeks’ gestation.MethodsAn international, multicenter, double-blinded, randomized trial of intratracheal budesonide (a corticosteroid) mixed with surfactant for extremely preterm infants to increase survival free of BPD at 36 weeks’ postmenstrual age (PMA; primary outcome). Extremely preterm infants aged < 48 h after birth are eligible if (1) they are mechanically ventilated, or (2) they are receiving non-invasive respiratory support and there is a clinical decision to treat with surfactant. The intervention is budesonide (0.25 mg/kg) mixed with poractant alfa (200 mg/kg first intervention, 100 mg/kg if second intervention), administered intratracheally via an endotracheal tube or thin catheter. The comparator is poractant alfa alone (at the same doses). Secondary outcomes include the components of the primary outcome (death, BPD prior to or at 36 weeks’ PMA), and potential systemic side effects of corticosteroids. Longer-term outcomes will be published separately, and include cost-effectiveness, early childhood health until 2 years of age, and neurodevelopmental outcomes at 2 years of age (corrected for prematurity).Statistical analysis planA sample size of 1038 infants (519 in each group) is required to provide 90% power to detect a relative increase in survival free of BPD of 20% (an absolute increase of 10%), from the anticipated event rate of 50% in the control arm to 60% in the intervention (budesonide) arm, alpha error 0.05. To allow for up to 2% of study withdrawals or losses to follow-up, PLUSS aimed to enroll a total of 1060 infants (530 in each arm). The binary primary outcome will be reported as the number and percentage of infants who were alive without BPD at 36 weeks’ PMA for each randomization group. To estimate the difference in risk (with 95% CI), between the treatment and control arms, binary regression (a generalized linear multivariable model with an identity link function and binomial distribution) will be used. Along with the primary outcome, the individual components of the primary outcome (death, and physiological BPD at 36 weeks’ PMA), will be reported by randomization group and, again, binary regression will be used to estimate the risk difference between the two treatment groups for survival and physiological BPD at 36 weeks’ PMA.

Investigation of side effects to treatment and cause of death in 63 Scandinavian dogs suffering from meningoencephalitis of unknown origin: a retrospective study

BackgroundMeningoencephalitis of unknown origin is a common cause of severe neurological disease in dogs. The term covers a heterogeneous group of noninfectious inflammatory diseases, with immune dysregulation widely accepted as the underlying disease mechanism. Current treatment consists of immunosuppression, with corticosteroids being the mainstay of virtually all treatment regimens. However, side effects of corticosteroids can be severe, and might be the cause of death in some patients. This retrospective, multi-centric study aimed at describing a population of Scandinavian dogs with meningoencephalitis of unknown origin in regards to reported side effects and cause of death, and to highlight possible differences in survival, when comparing corticosteroid monotherapy with other treatment regimens.ResultsWithin the 5-year study period, 63 dogs were included. Of these, 35 (49.3%) died or were euthanized during the study period. Median survival time from time of diagnosis based on Kaplan-Meier curves for the overall population was 714 days (equivalent to around 25 months, range 0-1678 days). There was no statistically significant difference (P = 0.31) in survival between dogs treated with corticosteroid monotherapy (n = 26, median survival time 716 days, equivalent to around 25 months, range 5–911 days), dogs receiving a combination of corticosteroids and ciclosporin (n = 15, median survival time 916 days, equivalent to around 31 months, range 35–1678 days), and dogs receiving corticosteroids combined with either cytosine arabinoside, leflunomide, or a combination of 2 or more add-on drugs (n = 13, median survival time 1186 days, equivalent to around 40 months, range 121–1640 days). Side effects were registered for 47/63 dogs. Polyphagia (n = 37/47), polyuria/polydipsia (n = 37/47), diarrhea (n = 29/47) and lethargy (n = 28/47) were most frequently reported. The most common cause for euthanasia was relapse (n = 15/35, 42.9%), followed by insufficient or lack of treatment response (n = 9, 25.7%). Side effects were the direct cause of euthanasia in 2/35 dogs (5.7%).ConclusionsA large proportion of dogs in the overall population were euthanized due to relapse, emphasizing a need for treatment regimens aimed at specifically preventing relapse for an improved long-term survival. Side effects in dogs receiving corticosteroid monotherapy were rarely a direct cause of death, but were reported for all dogs. No statistically significant difference in survival was found when corticosteroid monotherapy was compared to other treatment regimens.

Public Awareness Regarding Corticosteroid Use and Side Effects: A Cross-Sectional Study in Riyadh, Saudi Arabia.

The administration of corticosteroids may have possible hazards, ranging from minor adverse medication reactions to more serious considerations. We aimed to assess levels of public awareness concerning corticosteroid use, side effects, and predictors of its use. A cross-sectional study was conducted online throughout the period of May to July 2023. The present investigation utilized a previously developed questionnaire tool. The study encompassed a cohort of 732 individuals. Upon inquiry regarding the adverse effects of corticosteroid treatment, the participants predominantly reported weight gain, skin alterations, and fluid retention leading to breathing difficulties, constituting 44.4%, 30.3%, and 27.7% of the responses, respectively. The prevailing adverse effects observed in individuals using corticosteroids were weight gain, alterations in mood, and changes in skin characteristics, which accounted for 38.1%, 25.7%, and 21.8% of reported cases, respectively. Individuals within the age range of 41-50 years and those who are currently not working show a higher propensity for utilizing corticosteroids in comparison to other demographic groups (p < 0.05). The level of general public knowledge about corticosteroids and the side effects connected with them in Saudi Arabia was adequate. Demographic factors, such as age, gender, and education, have an impact on the use of corticosteroids.

Long-Term Weight Changes After Starting Anti-IL-5/5Ra Biologics in Severe Asthma: The Role of Oral Corticosteroids.

Many patients with severe asthma are overweight or obese, often attributed to unintentional weight gain as a side effect of oral corticosteroids (OCSs). Anti-IL-5/5Ra biologics significantly reduce OCS use, but their long-term effects on weight are unknown. To examine (1) weight change up to 2 years after anti-IL-5/5Ra initiation in subgroups on the basis of maintenance OCS use at start of treatment and (2) whether cumulative OCS exposure before or changes in OCS exposure during treatment are related to weight change. Real-world data on weight and cumulative OCS dose from adults included in the Dutch Registry of Adult Patients with Severe asthma for Optimal DIsease management before and at least 2 years after starting anti-IL-5/5Ra were analyzed using linear mixed models and linear regression analyses. For the included 389 patients (55% female; mean body mass index, 28 ± 5 kg/m2; 58% maintenance OCS), mean weight decreased-0.27 kg/y (95% CI,-0.51 to-0.03; P= .03), with more weight loss in patients with maintenance OCS use than in those without maintenance OCS use (-0.87 kg/y [95% CI,-1.21 to-0.52; P < .001] vs+0.54 kg/y [0.26 to 0.82; P < .001]). Greater weight loss at 2 years was associated with higher cumulative OCS dose in the 2 years before anti-IL-5/5Ra initiation (β=-0.24 kg/g; 95% CI,-0.38 to-0.10; P < .001) and, independently, greater reduction in cumulative OCS dose during follow-up (β= 0.27 kg/g; 95% CI, 0.11 to 0.43; P < .001). Anti-IL-5/5Ra therapy is associated with long-term weight reduction, especially in patients with higher OCS exposure before treatment and those able to reduce OCS use during treatment. However, the effect is small and does not apply to all patients, and so additional interventions seem necessary if weight change is desired.

Perception and usage of short-term prednisone and prednisolone in dogs.

Corticosteroids are widely used with low rates of reported side effects and a broad level of comfort in the hands of most veterinarians. With a low side effect reporting level of < 5% and high level of comfort there may be complacency and underestimation of the impact side effects of corticosteroids may have on a pet and pet owner. The objective of this clinical study was to describe the experience and perception of an owner who administered anti-inflammatory doses of oral prednisolone and prednisone to their dog for up to 14days. We hypothesized dogs receiving anti-inflammatory doses of prednisone and prednisolone would experience much greater rates of side effects by day 14 then reported in current literature. There were 45 dogs initially enrolled in the study. At each study point, 31 owners provided results. On day 5, 74% (23/31) reported at least 1 change in their dog's behavior including polyuria, polydipsia, polyphagia, polypnea and/or increased vocalization, with 11 individuals (35%) reporting these changes greatly increased. On day 14, 90% of owners (28/31) reported at least 1 change in their dog's behavior including polyuria, polydipsia, polyphagia, and/or polypnea as the most common changes noted. Overall, 61% (19/31) of owners reported an increase in filling of the water bowl over baseline and one-third (11/31) of pet owners reported cleaning up urinary accidents for pets who had been continent prior to the start of the study. Pet owner steroid satisfaction remained high through day 14 at 4.5/5 (1 = very unsatisfied, 5 = very satisfied). This study highlights the impact short term anti-inflammatory doses of prednisone or prednisolone have on dog behaviour and confirms our hypothesis that by day 14, 90% of dogs experienced one or more behaviour changes, with polyuria and polydipsia most commonly reported. Adverse events were noted regardless of starting dosage or regimen. Although most pet owners expressed satisfaction with steroid treatment due to its high efficacy, 70% would select a more costly treatment if that treatment had fewer side effects.

A Mixed-Method Study Exploring Patient-Experienced and Caregiver-Reported Benefits and Side Effects of Corticosteroid Use in Duchenne Muscular Dystrophy.

Corticosteroids are recommended to all people with Duchenne as standard of care; patient experience data is important to guide corticosteroid decision making and as a comparator for new treatment options. This study assesses patient and caregiver-reported benefits and side effects from corticosteroids to treat Duchenne muscular dystrophy, their importance, and satisfaction. Using one-on-one interviews (n = 28) and an online survey (n = 236), parents and adults with Duchenne reported corticosteroid benefits and side effects rated as both experienced and important. Benefits to breathing, heart function, arm strength, slowing progression of weakness, and getting around were rated as particularly important, regardless of ambulatory status. Important side effects included increased fracture risk, unwanted weight gain, and diabetes/prediabetes. Parents rated behavior issues and adults rated delayed puberty as having high importance. Being ambulatory was independently associated with reporting more net benefit (p = 0.02). For side effects, parent scores were significantly higher than adult score (p = 0.02). Corticosteroid type was not significant. Participants were, overall, satisfied with corticosteroids (means ranging from 6.2 to 7.7 on a scale of 0-10), with no significant differences based on corticosteroid type. Overall, most participants were satisfied with the use of corticosteroids. While a range of side effects were rated as important and relatively common, individuals using corticosteroids and their caregivers indicate that benefits outweigh the side effects. Qualitative data indicate that high acceptability is influenced by lack of treatment alternatives. Patient experience data on use of corticosteroids in Duchenne may be relevant to drug development, regulatory assessment of new treatments, and to families making decisions about corticosteroid use.

Instrumented cervical fusion using patient specific end-plate conforming interbody devices with a micro-porous structure in nine dogs with disk-associated cervical spondylomyelopathy.

To report the medium and long-term outcome of nine dogs with disk-associated cervical spondylomyelopathy (DA-CSM), treated by instrumented interbody fusion using patient specific end-plate conforming device that features a micro-porous structure to facilitate bone in-growth. A retrospective clinical study. Nine medium and large breed dogs. Medical records at two institutions were reviewed between January 2020 and 2023. Following magnetic resonance imaging (MRI) diagnosis of DA-CSM, pre-operative computed tomography (CT) scans were exported to computer software for in-silico surgical planning. Interbody devices were 3D-manufactured by selecting laser melting in titanium alloy. These were surgically implanted at 13 segments alongside mono-or bi-cortical vertebral stabilization systems. Follow-up included neurologic scoring and CT scans post-operative, at medium-term follow up and at long-term follow-up where possible. Interbody fusion and implant subsidence were evaluated from follow-up CT scans. Nine dogs were diagnosed with DA-CSM between C5-C7 at a total of 13 operated segments. Medium-term follow up was obtained between 2 and 8 months post-operative (3.00 ± 1.82 months). Neurologic scoring improved (p = 0.009) in eight of nine dogs. Distraction was significant (p < 0.001) at all segments. Fusion was evident at 12/13 segments. Subsidence was evident at 3/13 operated segments but was only considered clinically relevant in one dog that did not improve; as clinical signs were mild, revision surgery was not recommended. Long-term follow up was obtained between 9 and 33 months (14.23 ± 8.24 months); improvement was sustained in 8 dogs. The dog that suffered worsened thoracic limb paresis at medium-term follow up was also diagnosed with immune-mediated polyarthropathy (IMPA) and was euthanased 9 months post-operative due to unacceptable side-effects of corticosteroid therapy. End-plate conforming interbody devices with a micro-porous structure were designed, manufactured, and successfully implanted in dog with DA-CSM. This resulted in CT-determined fusion with minimal subsidence in the majority of operated segments. The technique described can be used to distract and fuse cervical vertebrae in dogs with DA-CSM, with favorable medium-and long-term outcomes.

H16 Arsenic to biologics: psoriasis treatment through the ages

Abstract In the 19th century when arsenic was the recommended treatment for psoriasis, little consideration was given to the toxic side-effects of the potent carcinogen. Thomas Girdlestone, an English physician, is said to have been the first to advocate for the use of arsenic to treat psoriasis. Girdlestone prescribed Fowler’s solution, a solution of potassium arsenite 1%. In 1876, Alexander John Balmanno Squire inadvertently discovered dithranol, a known treatment for ringworm, to be efficacious in treating psoriasis. However, it was Eugen Galewsky, in 1916, who then went on to synthesize anthralin, a synthetic form of dithranol, to target psoriasis. A key historical figure was William H. Geockerman, an American dermatologist, who developed Goekerman therapy—a regimen that combined the use of coal tar and ultraviolet (UV) light to treat moderate-to-severe plaque psoriasis. In 1953, John Ingram, an English dermatologist, discovered that the beneficial effects of dithranol paste could be enhanced by adding it to coal tar and UV light—later coined the ‘Ingram regimen’. Philip Showalter Hench, Edward Calvin Kendall and Tadeus Reichstein received the Nobel Prize in Medicine and Physiology for the development of cortisone; it proved to be useful in topically treating many skin diseases, but it had a limited effect on psoriasis. The production of synthetic corticosteroids soon followed, which, conversely, proved to be successful in treating psoriasis. However, the daunting side-effects of corticosteroids limited their long-term use. In 1951, a patient with rheumatoid arthritis showed dramatic improvement in their psoriasis when treated with aminopterin, as recorded by Richard Gubner, a New York cardiologist. PUVA was developed in the 1970s—a photochemotherapy for psoriasis that combined psoralen with UVA radiation to clear skin lesions. Interestingly, in 1500 Bc, the ancient Egyptians were known to use a combination of psoralen and sunlight to treat vitiligo. Furthermore, in the 1980s, researchers noted complete clearance of psoriasis in a patient with osteoporosis who was prescribed an oral form of vitamin D. This chance observation then led to the development of topical vitamin D analogues for the treatment of psoriasis that work by encouraging normal skin growth and slowing down overproduction of skin cells. Finally, in 2003, the first biologic treatments were approved for psoriasis by the US Food and Drug Administration—a significantly safer and more efficacious alternative to the controversial arsenic treatments that were used over 200 years ago.
