Biweekly vs Triweekly Cabazitaxel in Older Patients With Metastatic Castration-Resistant Prostate Cancer: The CABASTY Phase 3 Randomized Clinical Trial.

Importance: Many patients 65 years or older with metastatic castration-resistant prostate cancer (mCRPC) are denied taxane chemotherapy because this treatment is considered unsuitable. Objective: To determine whether biweekly cabazitaxel (CBZ), 16 mg/m2 (biweekly CBZ16), plus prophylactic granulocyte colony-stimulating factor (G-CSF) at each cycle reduces the risk of grade 3 or higher neutropenia and/or neutropenic complications (eg, febrile neutropenia, neutropenic infection, or sepsis) compared with triweekly CBZ, 25 mg/m2 (triweekly CBZ25), plus G-CSF (standard regimen). Design, Setting, and Participants: A total of 196 patients 65 years or older with progressive mCRPC were enrolled in this prospective phase 3 randomized clinical trial conducted in France (18 centers) and Germany (7 centers) between May 5, 2017, and January 7, 2021. All patients had received docetaxel and at least 1 novel androgen receptor-targeted agent. Interventions: Patients were randomly assigned 1:1 to receive biweekly CBZ16 plus G-CSF and daily prednisolone (experimental group) or triweekly CBZ25 plus G-CSF and daily prednisolone (control group). Main Outcome and Measures: The primary end point was the occurrence of grade 3 or higher neutropenia measured at nadir and/or neutropenic complications. Results: Among 196 patients (97 in the triweekly CBZ25 group and 99 in the biweekly CBZ16 group), the median (IQR) age was 74.6 (70.4-79.3) years, and 181 (92.3%) had an Eastern Cooperative Oncology Group performance status of 0 or 1. The median (IQR) follow-up duration was 31.3 (22.5-37.5) months. Relative dose intensities were comparable between groups (median [IQR], 92.7% [83.7%-98.9%] in the triweekly CBZ25 group vs 92.8% [87.0%-98.9%] in the biweekly CBZ16 group). The rate of grade 3 or higher neutropenia and/or neutropenic complications was significantly higher with triweekly CBZ25 vs biweekly CBZ16 (60 of 96 [62.5%] vs 5 of 98 [5.1%]; odds ratio, 0.03; 95% CI, 0.01-0.08; P < .001). Grade 3 or higher adverse events were more common with triweekly CBZ25 (70 of 96 [72.9%]) vs biweekly CBZ16 (55 of 98 [56.1%]). One patient (triweekly CBZ25 group) died of a neutropenic complication. Conclusions and Relevance: In this randomized clinical trial, compared with the standard regimen, biweekly CBZ16 plus G-CSF significantly reduced by 12-fold the occurrence of grade 3 or higher neutropenia and/or neutropenic complications, with comparable clinical outcomes. The findings suggest that biweekly CBZ16 regimen should be offered to patients 65 years or older with mCRPC for whom the standard regimen is unsuitable.

High-dose (40†mg) versus low-dose (20†mg) prednisolone for treating sarcoidosis: a randomised trial (SARCORT trial).

BACKGROUND: Current guidelines recommend 20-40 mg·day-1 of oral prednisolone for treating pulmonary sarcoidosis. Whether the higher dose (40 mg·day-1) can improve outcomes remains unknown. METHODS: We conducted an investigator-initiated, single-centre, open-label, parallel-group, randomised controlled trial (ClinicalTrials.gov identifier NCT03265405). Consecutive subjects with pulmonary sarcoidosis were randomised (1:1) to receive either high-dose (40 mg·day-1 initial dose) or low-dose (20 mg·day-1 initial dose) oral prednisolone, tapered over 6 months. The primary outcome was the frequency of relapse or treatment failure at 18 months from randomisation. Key secondary outcomes included the time to relapse or treatment failure, overall response, change in forced vital capacity (FVC, in litres) at 6 and 18 months, treatment-related adverse effects and health-related quality of life (HRQoL) scores using the Sarcoidosis Health Questionnaire and Fatigue Assessment Scale. FINDINGS: We included 86 subjects (43 in each group). 42 and 43 subjects completed treatment in the high-dose and low-dose groups, respectively, while 37 (86.0%) and 41 (95.3%), respectively, completed the 18-month follow-up. 20 (46.5%) subjects had relapse or treatment failure in the high-dose group and 19 (44.2%) in the low-dose group (p=0.75). The mean time to relapse/treatment failure was similar between the groups (high-dose 307 days versus low-dose 269 days, p=0.27). The overall response, the changes in FVC at 6 and 18 months and the incidence of adverse effects were also similar. Changes in HRQoL scores did not differ between the study groups. INTERPRETATION: High-dose prednisolone was not superior to a lower dose in improving outcomes or the HRQoL in sarcoidosis and was associated with similar adverse effects.

Case Report: A Rare Case of Elderly-Onset Adult-Onset Still's Disease in a Patient With Systemic Lupus Erythematosus.

The rare systemic inflammatory disorder 'adult-onset Still's disease (AOSD)' is characterized by recurrent fever, evanescent rash, arthralgia, and leukocytosis with neutrophilia. The Yamaguchi criteria are widely used to diagnose AOSD; these criteria can be used for diagnosis after a wide range of infectious, rheumatic, and neoplastic diseases have been excluded. AOSD generally does not overlap with other rheumatic diseases. We present the rare case of an 80-year-old Japanese woman who presented with arthralgia, fever, and skin rash during treatment for systemic lupus erythematosus (SLE), which was finally diagnosed as an overlap of AOSD. Blood tests revealed leukocytosis with neutrophilia, high C-reactive protein (CRP), and liver dysfunction. Her anti-ds-DNA antibody titer and serum complement titer were at the same level as before and remained stable. We suspected AOSD based on the high serum ferritin level but hesitated to diagnose AOSD because of the patient's SLE history. We measured serum interleukin (IL)-18; it was extremely high at 161,221 pg/mL, which was strongly suggestive of AOSD. We thus diagnosed AOSD complicated during the course of treatment for SLE. The patient's arthralgia and high CRP level persisted after we increased her oral prednisolone dose and added oral methotrexate, but her symptoms eventually improved with the addition of intravenous tocilizumab. We note that the presence of autoantibodies or other rheumatic diseases cannot be absolutely ruled out in the diagnosis of AOSD. Although high serum IL-18 levels are not specific for AOSD, the measurement of serum IL-18 may aid in the diagnosis of AOSD in similar rare cases.

Abiraterone acetate and prednisolone with or without enzalutamide for high-risk non-metastatic prostate cancer: a meta-analysis of primary results from two randomised controlled phase 3 trials of the STAMPEDE platform protocol.

BACKGROUND: Men with high-risk non-metastatic prostate cancer are treated with androgen-deprivation therapy (ADT) for 3 years, often combined with radiotherapy. We analysed new data from two randomised controlled phase 3 trials done in a multiarm, multistage platform protocol to assess the efficacy of adding abiraterone and prednisolone alone or with enzalutamide to ADT in this patient population. METHODS: These open-label, phase 3 trials were done at 113 sites in the UK and Switzerland. Eligible patients (no age restrictions) had high-risk (defined as node positive or, if node negative, having at least two of the following: tumour stage T3 or T4, Gleason sum score of 8-10, and prostate-specific antigen [PSA] concentration ≥40 ng/mL) or relapsing with high-risk features (≤12 months of total ADT with an interval of ≥12 months without treatment and PSA concentration ≥4 ng/mL with a doubling time of <6 months, or a PSA concentration ≥20 ng/mL, or nodal relapse) non-metastatic prostate cancer, and a WHO performance status of 0-2. Local radiotherapy (as per local guidelines, 74 Gy in 37 fractions to the prostate and seminal vesicles or the equivalent using hypofractionated schedules) was mandated for node negative and encouraged for node positive disease. In both trials, patients were randomly assigned (1:1), by use of a computerised algorithm, to ADT alone (control group), which could include surgery and luteinising-hormone-releasing hormone agonists and antagonists, or with oral abiraterone acetate (1000 mg daily) and oral prednisolone (5 mg daily; combination-therapy group). In the second trial with no overlapping controls, the combination-therapy group also received enzalutamide (160 mg daily orally). ADT was given for 3 years and combination therapy for 2 years, except if local radiotherapy was omitted when treatment could be delivered until progression. In this primary analysis, we used meta-analysis methods to pool events from both trials. The primary endpoint of this meta-analysis was metastasis-free survival. Secondary endpoints were overall survival, prostate cancer-specific survival, biochemical failure-free survival, progression-free survival, and toxicity and adverse events. For 90% power and a one-sided type 1 error rate set to 1·25% to detect a target hazard ratio for improvement in metastasis-free survival of 0·75, approximately 315 metastasis-free survival events in the control groups was required. Efficacy was assessed in the intention-to-treat population and safety according to the treatment started within randomised allocation. STAMPEDE is registered with ClinicalTrials.gov, NCT00268476, and with the ISRCTN registry, ISRCTN78818544. FINDINGS: Between Nov 15, 2011, and March 31, 2016, 1974 patients were randomly assigned to treatment. The first trial allocated 455 to the control group and 459 to combination therapy, and the second trial, which included enzalutamide, allocated 533 to the control group and 527 to combination therapy. Median age across all groups was 68 years (IQR 63-73) and median PSA 34 ng/ml (14·7-47); 774 (39%) of 1974 patients were node positive, and 1684 (85%) were planned to receive radiotherapy. With median follow-up of 72 months (60-84), there were 180 metastasis-free survival events in the combination-therapy groups and 306 in the control groups. Metastasis-free survival was significantly longer in the combination-therapy groups (median not reached, IQR not evaluable [NE]-NE) than in the control groups (not reached, 97-NE; hazard ratio [HR] 0·53, 95% CI 0·44-0·64, p<0·0001). 6-year metastasis-free survival was 82% (95% CI 79-85) in the combination-therapy group and 69% (66-72) in the control group. There was no evidence of a difference in metatasis-free survival when enzalutamide and abiraterone acetate were administered concurrently compared with abiraterone acetate alone (interaction HR 1·02, 0·70-1·50, p=0·91) and no evidence of between-trial heterogeneity (I2 p=0·90). Overall survival (median not reached [IQR NE-NE] in the combination-therapy groups vs not reached [103-NE] in the control groups; HR 0·60, 95% CI 0·48-0·73, p<0·0001), prostate cancer-specific survival (not reached [NE-NE] vs not reached [NE-NE]; 0·49, 0·37-0·65, p<0·0001), biochemical failure-free-survival (not reached [NE-NE] vs 86 months [83-NE]; 0·39, 0·33-0·47, p<0·0001), and progression-free-survival (not reached [NE-NE] vs not reached [103-NE]; 0·44, 0·36-0·54, p<0·0001) were also significantly longer in the combination-therapy groups than in the control groups. Adverse events grade 3 or higher during the first 24 months were, respectively, reported in 169 (37%) of 451 patients and 130 (29%) of 455 patients in the combination-therapy and control groups of the abiraterone trial, respectively, and 298 (58%) of 513 patients and 172 (32%) of 533 patients of the combination-therapy and control groups of the abiraterone and enzalutamide trial, respectively. The two most common events more frequent in the combination-therapy groups were hypertension (abiraterone trial: 23 (5%) in the combination-therapy group and six (1%) in control group; abiraterone and enzalutamide trial: 73 (14%) and eight (2%), respectively) and alanine transaminitis (abiraterone trial: 25 (6%) in the combination-therapy group and one (<1%) in control group; abiraterone and enzalutamide trial: 69 (13%) and four (1%), respectively). Seven grade 5 adverse events were reported: none in the control groups, three in the abiraterone acetate and prednisolone group (one event each of rectal adenocarcinoma, pulmonary haemorrhage, and a respiratory disorder), and four in the abiraterone acetate and prednisolone with enzalutamide group (two events each of septic shock and sudden death). INTERPRETATION: Among men with high-risk non-metastatic prostate cancer, combination therapy is associated with significantly higher rates of metastasis-free survival compared with ADT alone. Abiraterone acetate with prednisolone should be considered a new standard treatment for this population.

Outcome of low-dose prednisolone use for the induction of remission in lupus nephritis patients.

OBJECTIVES: This study aimed to compare the efficacy of low-dose prednisolone with conventional high-dose regimen in proliferative lupus nephritis (LN) for remission. METHODS: This open-label randomized clinical trial was conducted in the Department of Rheumatology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. A total of 32 LN patients were randomized into low-dose (experimental) and high-dose (control) groups. All subjects received standard dose of intravenous (I/V) methylprednisolone and pulse I/V cyclophosphamide. Oral prednisolone, 0.5 mg/kg/d and 1 mg/kg/d were given to experimental and control groups respectively for initially 4 weeks then tapered. The patients were followed for 24 weeks. The rates of renal remission (complete and partial) were assessed at 24 weeks. The disease activity, biochemical markers, and quality of life were evaluated at baseline and at 24 weeks. RESULTS: Complete renal remission was achieved by 66.7% of patients in each group (P = .99). Renal remission (partial/complete) was achieved by 86.7% and 83.3% of patients in the prednisolone low-dose group and high-dose group respectively (P = .99). In between groups, no significant difference was observed in the improvement of active urinary sediments, serum creatinine level, anti-double-stranded DNA level, complements level, disease activity and Short Form-12 score. The prednisolone dose-related adverse events like cushingoid facies, abdominal stria, infections and serious adverse events like death occurred more in the high-dose prednisolone group. CONCLUSIONS: It has been observed that low-dose prednisolone regimen may be effective in LN. Steroid dose-related side effects and rate of infections were lower in this group.

Changes in oral corticosteroid use in asthma treatment-A 20-year Danish nationwide drug utilisation study.

Oral corticosteroids (OCS) are used in asthma management but can cause serious adverse effects. We aimed to investigate the usage trends in a nationwide asthma cohort in Denmark from 1999 to 2018. Using national registers, we identified young adults (18-45 years) with two or more asthma drug collections within 12 months since the age of 15 years as indicative of active asthma. OCS exposure level was stratified as high use (≥5 mg prednisolone/day/year) and low use (<5 mg/day/year). Lorenz curves were computed to illustrate potential skewness of consumption among the OCS users. We identified 318 950 individuals with a median age of 29 years (IQR 20-38 years) whereof 57% were women. The 1-year prevalence of OCS users was stable at 4.8% (median, IQR 4.7%-4.8%), but with nearly 40% decrease in high-users from 0.54% in 1999 to 0.33% in 2018. The median annual exposure decreased from 500 mg/year (1999) to 250 mg/year (2018). We found a substantial skewness in the distribution of OCS usage with 10% of users accounting for almost 50% of all OCS use. The prevalence of OCS users among young adults with active asthma has been relatively stable from 1999 to 2018, but with a decreasing prevalence of high-users and annual consumption.

Potential benefits of precise corticosteroid therapy for critical COVID-19.

This study was aimed to explore the precise dose of corticosteroid therapy in critical COVID-19. A total of forty-five critical COVID-19 patients were enrolled. The process of critical COVID-19 was divided into alveolitis and fibrosis stages. Most nonsurvivors died in fibrosis phase. Nonsurvivors had more dyspnea symptoms, fewer days of hospitalization, shorter duration of alveolitis and fibrosis. High-dose daily corticosteroid therapy (≥150 mg/d) was associated with shorter survival time and lower lymphocyte count in fibrosis phase. Moreover, a high cumulative dose (≥604 mg) was tied to longer duration of virus shedding, lower oxygenation index (OI), higher incidence of tracheal intubation, fewer lymphocytes and higher levels of C-reactive protein (CRP) and lactate dehydrogenase (LDH). In alveolitis phase, the low-to-moderate-dose daily corticosteroid therapy and a small cumulative dose reduced lymphocytes. In conclusion, low-to-moderate dose corticosteroids may be beneficial in the fibrosis phase. High-dose corticosteroid therapy in the fibrosis phase aggravates the severity of critical COVID-19.

New-onset Evans syndrome associated with systemic lupus erythematosus after BNT162b2 mRNA COVID-19 vaccination.

Evans syndrome presents as concurrent autoimmune hemolytic anemia (AIHA) and immune thrombocytopenia (ITP). Systemic lupus erythematosus (SLE) is the most frequent autoimmune disorder associated with Evans syndrome. We herein report a case of new-onset Evans syndrome associated with SLE after BNT162b2 mRNA coronavirus disease 2019 (COVID-19) vaccination in a 53-year-old woman. Blood examination at diagnosis showed hemolytic anemia with a positive Coombs test and thrombocytopenia. Hypocomplementemia and the presence of lupus anticoagulant indicated a strong association with SLE. Prednisolone administration rapidly restored hemoglobin level and platelet count. This case suggests that mRNA COVID-19 vaccination may cause an autoimmune disorder. Physicians should be aware of this adverse reaction by mRNA COVID-19 vaccination and should consider the benefits and risks of vaccination for each recipient.

Successful rituximab treatment of an elderly Japanese patient with HHV8-positive, HIV-negative multicentric Castleman disease.

Human herpesvirus-8 (HHV8)-positive, human immunodeficiency virus (HIV)-negative multicentric Castleman disease (MCD) is a rare and age-related lymphoproliferative disorder caused by cytokine storm. Rituximab treatment is currently recommended because B-cell depletion eliminates the primary reservoir for HHV8. We report the first case of effective rituximab treatment of a Japanese patient (an 87-year-old woman) with this disorder. Her inflammatory symptoms and lymphadenopathy improved after medium-dose steroid therapy, but these symptoms recurred during steroid tapering. After one course of rituximab therapy, she achieved sustained remission. HHV8-associated MCD should be considered as a possible diagnosis in HIV-negative patients with inflammatory symptoms and lymphadenopathy.

Optimizing the corticosteroid dose in steroid-sensitive nephrotic syndrome.

The use of corticosteroids in the treatment of steroid-sensitive nephrotic (SSNS) syndrome in children has evolved surprisingly slowly since the ISKDC consensus over 50 years ago. From a move towards longer courses of corticosteroid to treat the first episode in the 1990s and 2000s, more recent large, well-designed randomized controlled trials (RCTs) have unequivocally shown no benefit from an extended course, although doubt remains whether this applies across all age groups. With regard to prevention of relapses, daily ultra-low-dose prednisolone has recently been shown to be more effective than low-dose alternate-day prednisolone. Daily low-dose prednisolone for a week at the time of acute viral infection seems to be effective in the prevention of relapses but the results of a larger RCT are awaited. Recently, corticosteroid dosing to treat relapses has been questioned, with data suggesting lower doses may be as effective. The need for large RCTs to address the question of whether corticosteroid doses can be reduced was the conclusion of the authors of the recent corticosteroid therapy for nephrotic syndrome in children Cochrane update. This review summarizes development in thinking on corticosteroid use in SSNS and makes suggestions for areas that merit further scrutiny.

Risk factors for failure of ileal pouch-anal anastomosis in patients with refractory ulcerative colitis.

BACKGROUND: Proctocolectomy with ileal pouch-anal anastomosis is the standard surgical procedure for ulcerative colitis refractory to medical treatment. In a few cases, ileal pouch-anal anastomosis cannot be completed due to intraoperative technical problems. The aim of this single-center study was to identify risk factors for a technically failed ileal pouch-anal anastomosis. METHODS: In total, 391 patients with ulcerative colitis who received ileal pouch-anal anastomosis were identified. Clinical and perioperative data from patients with successful ileal pouch-anal anastomosis (IPAA+) were compared to data from failed ileal pouch-anal anastomosis (IPAA-). Definition of failed ileal pouch-anal anastomosis was intraoperative failure to perform ileal pouch-anal anastomosis. Risk factors for failed ileal pouch-anal anastomosis were assessed by logistic regression. Cut-off values were calculated on the basis of receiver operating characteristic curves and the Youden Index. RESULTS: The rate of failed ileal pouch-anal anastomosis was 26 of 391 (6.6%). In 22 of 26 cases (84.6%), there was an insufficient length of the small intestinal mesentery. Patients with failed ileal pouch-anal anastomosis were more often male (80.8% vs 54.5%, P = .009), older (47.1 ± 14.1 vs 39.2 ± 12.8 years, P = .007), had a higher body mass index 27.2 ± 4.5 vs 23.7 ± 4.3 kg/m2, P < .001), and had extraintestinal manifestations more frequently (65.4% vs 26.3%, P < .001). Further risk factors for failed ileal pouch-anal anastomosis were hypertension and Cushing's syndrome. CONCLUSION: Technical failure of ileal pouch-anal anastomosis is elevated in patients with higher body mass index, with refractory ulcerative colitis, and/or extended immunosuppressive medication. Three-staged ileal pouch-anal anastomosis and optimizing preoperative conditions may help to elevate the rate of successful ileoanal pouch construction in these patients.

Abiraterone acetate versus nonsteroidal antiandrogen with androgen deprivation therapy for high-risk metastatic hormone-sensitive prostate cancer.

BACKGROUND: Although prostate cancer is a very common form of malignancy in men, the clinical significance of androgen deprivation therapy (ADT) with abiraterone acetate versus the nonsteroidal antiandrogen bicalutamide has not yet been verified in patients with high-risk metastatic hormone-sensitive prostate cancer (mHSPC). The present study was designed to initiate this verification in real-world Japanese clinical practice. METHODS: We retrospectively analyzed the records of 312 patients with high-risk mHSPC based on LATITUDE criteria and had received ADT with bicalutamide (n = 212) or abiraterone acetate (n = 100) between September 2015 and December 2020. Bicalutamide was given at 80 mg daily and abiraterone was given at 1000 mg daily as four 250-mg tablets plus prednisolone (5-10 mg daily). Overall survival (OS), cancer-specific survival (CSS), and time to castration-resistant prostate cancer (CRPC) were compared. The prognostic factor for time to CRPC was analyzed by Cox proportional hazard model. RESULTS: Patients in the bicalutamide group were older, and more of them had poor performance status (≧2), than in the abiraterone group. Impaired liver function was noted in 2% of the bicalutamide group and 16% of the abiraterone group (p < 0.001). Median follow-up was 22.5 months for bicalutamide and 17 months for abiraterone (p < 0.001). Two-year OS and CSS for bicalutamide versus abiraterone was 77.8% versus 79.5% (p = 0.793) and 81.1% versus 82.5% (p = 0.698), respectively. Median time to CRPC was significantly longer in the abiraterone group than in the bicalutamide group (NA vs. 13 months, p < 0.001). In multivariate analysis, Gleason score ≧9, high alkaline phosphatase, high lactate dehydrogenase, liver metastasis, and bicalutamide were independent prognostic risk factors for time to CRPC. Abiraterone prolonged the time to CRPC in patients with each of these prognostic factors. CONCLUSIONS: Despite limitations regarding the time-dependent bias, ADT with abiraterone acetate significantly prolonged the time to CRPC compared to bicalutamide in patients with high-risk mHSPC. However, further study with longer follow-up is needed.

Primeiros casos de rejeição em transplante penetrante após vacina contra COVID-19 / First cases of penetrating corneal transplant rejection after COVID-19 vaccines

RESUMO Este artigo descreve dois casos de reação imunológica de rejeição de transplante penetrante após a aplicação de dois tipos de vacina contra a COVID-19 - CoronaVac (Sinopharm/Butantan) e MRNA BNT162&2 (Pfizer-BioNTech) - com intervalo de 1 e 10 dias, respectivamente. A rejeição se manifestou com hiperemia, edema corneano e embaçamento da visão, que responderam rapidamente ao uso de corticoide tópico e subconjuntival. Até onde sabemos, este é o primeiro relato de rejeição de transplante penetrante de córnea pós-vacina anti-COVID-19. Recomendamos, presentemente, como prevenção, colírio de prednisolona a 1% 4 dias antes e durante 2 semanas após receber qualquer tipo de vacina para a COVID-19.

ABSTRACT This paper describes two cases of allograft corneal transplant rejection after the application of two types of COVID-19 vaccines - Coronavac (Sinopharm/Butantan) and MRNA BNT162&2 (Pfizer-BioNTech) vaccines - with an interval of 1 to 10 days, respectively. The rejection manifested in the form of corneal edema, hyperemia and blurred vision, which responded rapidly to the use of topical and subconjunctival corticosteroid. As far as we know, this is the first published report of immunological rejection of penetrating corneal transplant after COVID-19 vaccination. As a preventative measure, we now recommend the use of 1% prednisolone eye drop 4 days before and during 2 weeks after having received any type of COVID-19 vaccine.

A 56-Year-Old Man With Emphysema, Rash, and Arthralgia.

CASE PRESENTATION: A 56-year-old man presented to the pulmonary clinic with dyspnea and hypoxemia on exertion. He was an avid biker and skier who had noticed a significant decrease in high-level physical activity over the past 3 years. He reported dyspnea, desaturations at altitudes higher than 9,000 feet, dry cough, tachycardia, and palpitations with exercise. Review of systems was also notable for gluten-intolerance, Raynaud's phenomenon, recurrent skin lesions and joint swelling, pain, and stiffness in the areas overlying the jaw, wrists, knees, and ankles (after capsaicin exposure). He denied fever, chills, anorexia, weight loss, hair loss, ocular symptoms, jaw claudication, chest pain, or lower extremity swelling. He had a five pack-year smoking history, no history of prematurity, childhood asthma, recurrent infections, or environmental and occupational exposure. Based on pulmonary function tests from an outside provider, he had received a diagnosis of exercise-induced asthma and had been prescribed an albuterol inhaler to use on an as-needed basis, which failed to improve his symptoms. He was later prescribed a mometasone-formoterol inhaler, still with no symptomatic improvement.

Corticosteroid Use and Risk of Herpes Zoster in a Population-Based Cohort.

OBJECTIVE: To examine the relationship between corticosteroid use and herpes zoster risk. METHODS: With data from a large cohort of adults (the 45 and Up Study) recruited between 2006 and 2009 and linked to health data sets, the effect of corticosteroid use on zoster risk was analyzed by Cox proportional hazards models, adjusting for age, sex, and other characteristics. RESULTS: During 602,152 person-years (median, 7.36 years) of follow-up, there were 20,048 new systemic corticosteroid users and 6294 incident herpes zoster events among 94,677 participants (zoster incidence, 11.0 per 1000 person-years). Compared with nonusers, the risk of zoster was 59% higher in those using systemic corticosteroids (adjusted hazard ratio [aHR], 1.59; 95% CI, 1.48 to 1.71) and greater with higher cumulative doses: aHR of 1.32 (95% CI, 1.17 to 1.48), 1.74 (95% CI, 1.55 to 1.95), and 1.80 (95% CI, 1.61 to 2.02) for use of less than 500 mg, 500 mg to less than 1000 mg, and 1000 mg or more prednisolone equivalents, respectively (P value for trend, <.001). Compared with nonusers, zoster risk increased significantly (aHR, 6.00; 95% CI, 4.85 to 7.42) in the month after a single prescription of systemic corticosteroids and returned to levels similar to those in nonusers by the third month after dispensing (aHR, 0.91; 95% CI, 0.49 to 1.69). CONCLUSION: Practitioners should be alert to the increased risk of zoster among patients taking systemic corticosteroids. Given the significant morbidity from zoster, particularly in older adults, these findings support judicious prescribing of corticosteroids, including using as low a dose and as short a course as possible.

Pilot study of dogs with suppurative and non-suppurative Malassezia otitis: A case series.

BACKGROUND: Rarely, Malassezia otitis presents as a painful, erosive otitis with an otic discharge containing Malassezia and neutrophils on cytology. There are no published reports of this type of suppurative Malassezia otitis (SMO). The role of Malassezia hypersensitivity in otitis is still unknown, and no association has been demonstrated with SMO. We compared Malassezia IgE levels, intradermal test and histology changes in SMO dogs with the more conventional Malassezia otitis (MO) presentation. RESULTS: Three dogs (case 1, case 2 and case 3) were diagnosed with SMO, one dog (case 4) was diagnosed with unilateral MO and unilateral SMO, and one dog (case 5) was diagnosed with MO. Only one case (case 4) with SMO/MO had a positive Intradermal Allergy Test (IDAT) and elevated IgE levels for Malassezia. Histopathology findings from SMO revealed: interface dermatitis (case 1 and 3), lymphocytic dermatitis (case 2) and chronic hyperplastic eosinophilic and lymphoplasmacytic dermatitis (case 4). Histopathology findings from MO showed perivascular dermatitis (case 4 and 5). All the cases were treated successfully. CONCLUSIONS: SMO presents with a distinct clinical phenotype in comparison with conventional MO. No consistent aetiology could be isolated. In these clinical cases it is possible that previous treatments could have influenced the results. More research is needed to understand the possible aetiologies and the pathogenesis of SMO.

Orally Fast Disintegrating Cyclodextrin/Prednisolone Inclusion-Complex Nanofibrous Webs for Potential Steroid Medications.

Prednisolone is a widely used immunosuppressive and anti-inflammatory drug type that suffers from low aqueous solubility and bioavailability. Due to the inclusion complexation with cyclodextrins (CDs), prednisolone's drawbacks that hinder its potential during the administration can be eliminated effectively. Here, we have early shown the electrospinning of free-standing nanofibrous webs of CD/prednisolone inclusion complexes (ICs) in the absence of a polymer matrix. In this study, hydroxypropyl-beta-CD (HPßCD) has been used to form ICs with prednisolone and generate nanofibrous webs with a drug loading capacity of ∼10% (w/w). Pullulan/prednisolone nanofibrous webs have been also fabricated as a control sample having the same drug loading (∼10%, w/w). It has been demonstrated that prednisolone has been found in an amorphous state in the HPßCD/prednisolone nanofibrous web due to inclusion complexation, while it has retained its crystal structure in the pullulan/prednisolone nanofibrous web. Therefore, the HPßCD/prednisolone IC nanofibrous web has shown a faster and enhanced release profile and superior disintegration feature in artificial saliva than the pullulan/prednisolone nanofibrous web. The complexation energy calculated using ab initio modeling displayed a more favorable interaction between HPßCD and prednisolone in the case of a molar ratio of 2:1 than 1:1 (CD: drug). Here, the HPßCD/prednisolone IC nanofibrous web has been developed without using a toxic component or solvent to dissolve drug molecules and boost drug loading in amorphous nature. The investigation of IC nanofibrous webs has been conducted to formulate a promising alternative to the orally disintegrating tablet formulation of prednisolone in the market. The nanofibrous structure and the improved physicochemical properties of prednisolone arising with the complexation might ensure a faster disintegration and onset of action against commercially available and orally disintegrating delivery systems during the desired treatment.

Systemic corticosteroids in the treatment of warm autoimmune hemolytic anemia: A clinical setting perspective.

INTRODUCTION: There are unmet answers about the effect of the different forms of corticosteroids in the treatment of the warm autoimmune hemolytic anemia (WAIHA). We aimed to describe the initial response rate and the safety profile of different regimens and forms of parenteral corticosteroids versus the solo oral prednisolone as first-line strategies for newly diagnosed adult WAIHA. METHODS: We recruited 156 patients who treated with either oral prednisolone 1 mg/kg daily for 3 weeks or intravenous corticosteroids like dexamethasone 40 mg daily for 4 days, Methylprednisolone 1 g/day for 3 days, or Methylprednisolone 1 g/day for 5 days then followed by oral prednisolone 1 mg/kg/day for 3 weeks. Full clinical and laboratory evaluations were done every 3 days for 3 weeks. RESULTS: The primary outcome was the rate of response at the end of the third-week post treatment. The rate of response was more in the group started the treatment intravenously (81.6% versus 41.7% and p = 0.0001). Multivariate cox regression analysis proved the predictivity of intravenous corticosteroid therapy for initial response. CONCLUSION: The safety profile of the different forms and regimens of corticosteroids were comparable. Therefore, parenteral regimens can be used as a rescue treatment in severe cases of WAIHA.

HLA genotyping in Japanese patients with multiple myeloma receiving bortezomib: An exploratory biomarker study of JCOG1105 (JCOG1105A1).

Bortezomib (Btz) shows robust efficacy in patients with multiple myeloma (MM); however, some patients experience suboptimal responses and show specific toxicities. Therefore, we attempted to identify specific HLA alleles associated with Btz-related toxicities and response to treatment. Eighty-two transplant-ineligible patients with newly diagnosed MM enrolled in a phase II study (JCOG1105) comparing two less intensive melphalan, prednisolone, plus Btz (MPB) regimens were subjected to HLA typing. The frequency of each allele was compared between the groups, categorized based on toxicity grades and responses to MPB therapy. Among 82 patients, the numbers of patients with severe peripheral neuropathy (PN; grade 2 or higher), skin disorders (SD; grade 2 or higher), and pneumonitis were 16 (19.5%), 15 (18.3%), and 6 (7.3%), respectively. Complete response was achieved in 10 (12.2%) patients. Although no significant HLA allele was identified by multiple comparisons, several candidates were identified. HLA-B*40:06 was more prevalent in patients with severe PN than in those with less severe PN (odds ratio [OR] = 6.76). HLA-B*40:06 and HLA-DRB1*12:01 were more prevalent in patients with SD than in those with less severe SD (OR = 7.47 and OR = 5.55, respectively). HLA-DRB1*08:02 clustered in the group of patients with pneumonitis (OR = 11.34). Complete response was achieved in patients carrying HLA-DQB1*03:02, HLA-DQB1*05:01, and HLA-DRB1*01:01 class II alleles. HLA genotyping could help predict Btz-induced toxicity and treatment efficacy in patients with MM, although this needs further validation.
