Prednisone combined with letrozole reduced risk of ovarian hyperstimulation syndrome (OHSS) in women undergoing long-term gonadotropin-releasing hormone analog treatment

BACKGROUND

Ovarian hyperstimulation syndrome (OHSS) is a severe disease that can lead to serious complication. Letrozole has been applied during controlled ovarian hyperstimulation (COH) to reduce the rate of OHSS in women undergoing long-term Gonadotropin-releasing Hormone Analog (GnRHa) treatment for assisted fertility. Prednisone can prevent vasodilatation and increased vascular permeability, which is common during OHSS. However, few studies have evaluated the combined effect of letrozole and prednisone in preventing severe OHSS and is the aim of our retrospective study of patients receiving GnRHa treatment.

METHODS

A total of 296 women who accepted autologous in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatments were included in this retrospective study. There were three groups: 146 women had letrozole, including letrozole alone (LE group, n=60) and letrozole with prednisone (LE + Pre group, n=86), and 150 women had no treatment (C group). Severe OHSS was diagnosed according to clinical evidence of hydrothorax, severe dyspnea, oliguria/anuria, and intractable nausea/vomiting.

RESULTS

The addition of prednisone to letrozole successfully reduced the occurrence rate of severe OHSS than those women administered letrozole alone (55.0% vs. 70.6%, P=0.022). However, the ongoing pregnancy rate was lower in the LE + Pre group than that in the LE-alone group (64.3% vs. 87.0%, P=0.025). Surprisingly, progesterone level on the trigger day (>0.895 ng/mL) is a strong predictor for pregnancy failure with a specificity of 68.3% and sensitivity of 65.7% in the LE-alone group.

CONCLUSIONS

Treatment with a combination of letrozole and prednisone may lower the rate of severe OHSS in women with prolonged gonadotropin-releasing hormone agonist protocol during assisted fertility treatment. When the progesterone level on trigger day is over 0.895 ng/mL, letrozole treatment may negatively affect clinical pregnancy.

Prednisone Reprograms the Transcriptional Immune Cell Landscape in CNS Autoimmune Disease

Glucocorticoids (GCs) are widely used immunosuppressive drugs for autoimmune diseases, although considerable gaps exist between current knowledge of the mechanisms of GCs and their conclusive immune-regulatory effects. Here we generated a single-cell transcriptional immune cell atlas based on prednisone-treated or untreated experimental autoimmune uveitis (EAU) mice. Immune cells were globally activated in EAU, and prednisone partially reversed this effect in terms of cell composition, gene expression, transcription factor regulation, and cell-cell communication. Prednisone exerted considerable rescue effects on T and B cells and increased the proportion of neutrophils. Besides commonly regulated transcriptional factors (Fosb, Jun, Jund), several genes were only regulated in certain cell types (e.g. Cxcr4 and Bhlhe40 in T cells), suggesting cell-type-dependent immunosuppressive properties of GC. These findings provide new insights into the mechanisms behind the properties and cell-specific effects of GCs and can potentially benefit immunoregulatory therapy development.

Higher-risk myelodysplastic syndrome in an elderly patient: Long-term partial remission with low-dose prednisone, G-CSF, and epoetin alfa

Currently, most patients with higher-risk MDS are treated with 5-azacitidine or decitabine. These agents are toxic. The treatment described here is safe, devoid of toxicity, fosters improved quality of life, and helps reduce transfusion requirements.

A prospective trial of abiraterone acetate plus prednisone in Black and White men with metastatic castrate-resistant prostate cancer

BACKGROUND

Retrospective analyses of randomized trials suggest that Black men with metastatic castration-resistant prostate cancer (mCRPC) have longer survival than White men. The authors conducted a prospective study of abiraterone acetate plus prednisone to explore outcomes by race.

METHODS

This race-stratified, multicenter study estimated radiographic progression-free survival (rPFS) in Black and White men with mCRPC. Secondary end points included prostate-specific antigen (PSA) kinetics, overall survival (OS), and safety. Exploratory analysis included genome-wide genotyping to identify single nucleotide polymorphisms associated with progression in a model incorporating genetic ancestry. One hundred patients self-identified as White (n = 50) or Black (n = 50) were enrolled. Eligibility criteria were modified to facilitate the enrollment of individual Black patients.

RESULTS

The median rPFS for Black and White patients was 16.6 and 16.8 months, respectively; their times to PSA progression (TTP) were 16.6 and 11.5 months, respectively; and their OS was 35.9 and 35.7 months, respectively. Estimated rates of PSA decline by ≥50% in Black and White patients were 74% and 66%, respectively; and PSA declines to <0.2 ng/mL were 26% and 10%, respectively. Rates of grade 3 and 4 hypertension, hypokalemia, and hyperglycemia were higher in Black men.

CONCLUSIONS

Multicenter prospective studies by race are feasible in men with mCRPC but require less restrictive eligibility. Despite higher comorbidity rates, Black patients demonstrated rPFS and OS similar to those of White patients and trended toward greater TTP and PSA declines, consistent with retrospective reports. Importantly, Black men may have higher side-effect rates than White men. This exploratory genome-wide analysis of TTP identified a possible candidate marker of ancestry-dependent treatment outcomes.

A Rare Case of a Patient with Systemic Lupus Erythematosus who Presented with Rowell Syndrome Responding to Treatment with Hydroxychloroquine and Prednisone with One Year of Relapse Free Survival on Belimumab

Rowell Syndrome, first described in 1963 by Rowell et al., is an infrequently reported and unique syndrome occurring in patients with Systemic Lupus Erythematosus (SLE). This syndrome characteristically presents with erythema multiforme-like lesions as well as other specific immunologic and histopathologic manifestations. Since Rowell's original description, diagnostic criteria have been proposed and modified to better describe the syndrome. We describe a 32-year-old African American female patient with a previous history of SLE who presented with dermatologic, immunologic, and histopathologic manifestations that fit the modified diagnostic criteria for Rowell Syndrome.

Treatment of Metastatic Castration-resistant Prostate Cancer Patients With Abiraterone Acetate and Prednisone and Corresponding Survival Prognostic Factors

BACKGROUND/AIM

The aim of the study was to evaluate the combined treatment with abiraterone acetate and prednisone (AA+P) in patients with castration-resistant prostate cancer (mCPRC), and to identify the survival prognostic factors.

PATIENTS AND METHODS

Patients diagnosed with mCPRC not previously treated with chemotherapy and administered with AA+P were classified into two groups: those with lower and higher survival rates (at 30 months vs. 60 months).

RESULTS

A total of 53 patients were studied at the time of mCRPC diagnosis. Patients with the highest survival rate had suffered prostate cancer for >45 months. At the time of initial prostate cancer diagnosis, they belonged to the risk groups 1-4, had pain intensity measured according to the brief pain inventory (BPI) scale of 0-2, were treated with AA+P>16 months, and had the following tumour marker serum levels: LDH baseline ≤163 U/l, alkaline phosphatase at 6 months ≤56 U/l and PSA at 6 months ≤0.95 ng/ml.

CONCLUSION

Good response to treatment with AA+P for patients with mCRPC was demonstrated. Factors that contributed to the higher prognostic accuracy were time suffering from prostate cancer, the intensity of the pain measured by the BPI scale, the duration of AA+P treatment, and tumour marker levels.

Influence of Different Types of Corticosteroids on Heart Rate Variability of Individuals with Duchenne Muscular Dystrophy-A Pilot Cross Sectional Study

Individuals with Duchenne Muscular Dystrophy (DMD) have an impairment of cardiac autonomic function categorized by parasympathetic reduction and sympathetic predominance. The objective of this study was to assess the cardiac autonomic modulation of individuals with DMD undergoing therapy with Prednisone/Prednisolone and Deflazacort and compare with individuals with DMD without the use of these medications and a typically developed control group. Methods: A cross-sectional study was completed, wherein 40 boys were evaluated. The four treatment groups were: Deflazacort; Prednisone/Prednisolone; no corticoid use; and typical development. Heart Rate Variability (HRV) was investigated via linear indices (Time Domain and Frequency Domain) and non-linear indices Results: The results of this study revealed that individuals with DMD undertaking pharmacotherapies with Prednisolone demonstrated HRV comparable to the Control Typically Developed (CTD) group. In contrast, individuals with DMD undergoing pharmacotherapies with Deflazacort achieved lower HRV, akin to individuals with DMD without any medications, as demonstrated in the metrics: RMSSD; LF (n.u.), HF (n.u.), LF/HF; SD1, α1, and α1/α2, and a significant effect for SD1/SD2; %DET and Ratio; Shannon Entropy, 0 V%, 2 LV% and 2 ULV%. Conclusions: Corticosteroids have the potential to affect the cardiac autonomic modulation in adolescents with DMD. The use of Prednisone/Prednisolone appears to promote improved responses in terms of sympathovagal activity as opposed to Deflazacort.

Radix Paeoniae Rubra Ameliorates Lupus Nephritis in Lupus-Like Symptoms of Mrl Mice by Reducing Intercellular Cell Adhesion Molecule-1, Vascular Cell Adhesion Molecule-1, and Platelet Endothelial Cell Adhesion Molecule-1 Expression

OBJECTIVE

Vasculitis is the basic pathological change of systemic lupus erythematosus (SLE). Radix Paeoniae Rubra (RPR), a traditional Chinese herb with the function of reducing blood stasis, has anti-inflammatory and immunoregulatory properties. This study explored the effects of RPR on the kidneys of lupus-like symptoms of mrl (MRL/lpr) mice from the perspective of intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and platelet endothelial cell adhesion molecule-1 (PECAM-1).

METHODS

Eighteen MRL/lpr lupus model mice were randomly divided into three groups, the model control group, prednisone-treated group, and RPR-treated group, and 6 C57BL/ 6 mice were classified as a control group. After the mice had been treated for 12 weeks, the expression of ICAM-1, VCAM-1 and PECAM-1in the kidney was determined by immunohistochemistry and Reverse Transcription-Polymerase Chain Reaction (RT-PCR).

RESULTS

After 12 weeks, there were significant differences in body weight in the model, prednisone and RPR groups compared with the normal group (P <0.05). Pathological observation: Compared with the model group, the proliferation of inflammatory cells infiltrated glomeruli and interstitial cells in prednisone and RPR groups were reduced, and renal pathological damage was reduced. Compared with the model group, urine protein level of prednisone and RPR groups were reduced with no significance (P> 0.05). The mRNA expression levels of ICAM-1 and VCAM-1 were significantly reduced in the prednisone group and RPR group compared with the model group (P <0.05 or P <0.01). Meanwhile, the immunohistochemistry expressions of ICAM-1 and VCAM- 1 expressed in the kidney were significantly reduced in the prednisone group and RPR group (P <0.01 or P <0.05). However, The mRNA expression level and the immunohistochemistry expressions of PECAM-1 expressed in the kidney were reduced in each treatment group (prednisone group and RPR group), but these differences were not significant (P>0.05).

CONCLUSIONS

ICAM-1, VCAM-1 and PECAM-1 expression in the model group was found to be significantly increased. In addition, RPR could reduce the expression of ICAM-1, VCAM-1 and PECAM-1 in MRL/lpr lupus mice as effectively as prednisone, which may result in the dosage reduction of prednisone, thus decreasing the toxicity and improving the efficacy of prednisone - based treatment of SLE.

Combination of Rituximab, Low-Dose Cyclophosphamide, and Prednisone for Primary Membranous Nephropathy: A Case Series With Extended Follow Up

RATIONALE & OBJECTIVE

B-cell depletion with rituximab has emerged as a first-line therapy for primary membranous nephropathy (MN). However, most patients do not achieve complete remission with rituximab monotherapy. In this case series, we report longer-term remission and relapse rates, anti-phospholipase A₂ receptor (PLA₂R) antibody levels, B-cell levels, and serious adverse events in patients with primary MN who received rituximab combined with an initial short course of low-dose oral cyclophosphamide and a course of rapidly tapered prednisone.

STUDY DESIGN

Single-center retrospective case series.

SETTING & PARTICIPANTS

60 consecutive patients with primary MN treated with the combination of rituximab, low-dose cyclophosphamide, and prednisone at the Vasculitis and Glomerulonephritis Center at the Massachusetts General Hospital.

FINDINGS

After treatment initiation, median follow-up was 38 (interquartile range [IQR], 25-62) months; 100% of patients achieved partial remission, defined as a urinary protein-creatinine ratio (UPCR) < 3 g/g and a 50% reduction from baseline, at a median of 3.4 months. By 2 years after treatment initiation, 83% achieved complete remission, defined as a UPCR < 0.3 g/g. The median time to complete remission was 12.4 months. Immunologic remission (defined by an anti-PLA₂R titer < 14 RU/mL) was achieved by 86% and 100% of anti-PLA₂R seropositive patients (n = 29) at 3 and 6 months, respectively, after treatment initiation. After 1 year, the median UPCR fell from 8.4 (IQR, 5.0-10.7) to 0.3 (IQR, 0.2-0.8) g/g (P < 0.001). No patient relapsed throughout the duration of B-cell depletion. Relapse occurred in 10% of patients at 2 years after the onset of B-cell reconstitution following the last rituximab dose. Over a combined follow-up time of 228 patient-years, 18 serious adverse events occurred. One death occurred unrelated to treatment or primary MN, and 1 patient progressed to kidney failure requiring kidney replacement therapy.

LIMITATIONS

Absence of a comparison group.

CONCLUSIONS

All patients with primary MN treated with combination therapy achieved partial remission and most achieved a durable complete remission with an acceptable safety profile.

Unusual Bilateral Upper Extremity Pitting Edema in a Patient With Severe Dermatomyositis

A 56-year-old Hispanic female presented with six weeks of progressive dysphagia, proximal muscle weakness, erythematous rash, bilateral upper extremity pitting edema, and left lower extremity pitting edema. She had preserved heart function and a normal echocardiogram (ECG). She presented with elevated creatine kinase (CK) and aldolase, with normal renal function. Muscle biopsy suggested idiopathic polymyositis. No blood clot was seen on deep vein thrombosis (DVT) ultrasound. The myositis antibody panel showed the NXP-2 antibody, which is usually seen in pediatric dermatomyositis cases. In our literature search, extremity pitting edema is an unusual way of presentation in dermatomyositis. She responded with intravenous immunoglobulin (IVIg) and high-dose intravenous steroids. We used azathioprine for remission maintenance; her rash recurred after tapering steroids. We resumed tapering steroid therapy and started her on weekly methotrexate along with daily azathioprine. With this combination therapy, her rash and muscle function improved. We successfully tapered her steroids. In our literature search, combination therapy with azathioprine and methotrexate was not reported. Our patient is tolerating this therapy very well.

The Efficacy of High-Dose Dexamethasone vs. Other Treatments for Newly Diagnosed Immune Thrombocytopenia: A Meta-Analysis

Objective: To compare the therapeutic efficacies of high dose dexamethasone, prednisone and rituximab in combination with dexamethasone for newly diagnosed ITP (Immune Thrombocytopenia, ITP) patients. Methods and results: Relevant publications for this study were obtained by searching PubMed, Embase, Cochrane, and CNKI (National Knowledge Infrastructure, CNKI) databases following the PRISMA guidelines. A total of, 15 publications were retrieved that contained sufficient data from 1,362 patients for high quality analysis of this study endpoints. Data analysis was carried out using Stata 11.0 software. The primary outcomes were OR (Overall Response, OR) at 1 month after intervention and SR at 6 and 12 months. The secondary outcomes were AEs and relapse. There were no differences in the OR, while the SR was higher at 6 months (p = 0.001) as well as 12 months (p < 0.001) in the rituximab + dexamethasone group. In addition, the incidences of AEs (p = 0.008) were also higher in the rituximab + dexamethasone group. Dexamethasone was superior to prednisone based on OR (p = 0.006). We found no differences in SR at 6 months between dexamethasone and prednisone but SR at 12 months was higher in the dexamethasone group (p = 0.014). The relapse rate was higher in the high dose dexamethasone group compared to the rituximab + dexamethasone group (p = 0.042). Conclusion: This demonstrated that new treatment options such as Rituximab + dexamethasone, could be a good alternative to traditional therapy in improving long-term response and reducing the rate of relapse. However, further studies are required on the increased risk of AEs associated with Rituximab + dexamethasone.

Case Report: A Rare Case of Nasal Forehead Mass in Kimura's Disease

Background: Kimura's disease is a rheumatic immune disease and head and neck lymph nodes are often involved. A mass occurring in the nasal forehead is rare. Good prognosis after surgical resection by glucocorticoid therapy is more rare. Case Summary: We report the rare case of a nasal forehead mass in a 45-year-old male patient with Kimura's disease. The patient underwent resection of the mass in October 2018 in a local hospital and the postoperative pathology was unclear. He then underwent a second resection in our department in December 2019 mainly because growth of the mass was affecting his appearance. Postoperative pathology confirmed that the patient had Kimura's disease, and he accepted systemic treatment with prednisone. We followed the patient for 10 months after surgery. He is now recovering well and continues to be closely monitored during follow-up. Conclusion: It is rare that the painless mass in the nasal forehead is diagnosed as a Kimura's disease.After completely resection of the mass and systemic treatment with prednisone, the patient had a good outcome. We provide experience for the treatment of Kimura's disease in nasal forehead.

Steroid-Induced Sinus Bradycardia

Steroids are one of the most commonly used drugs and known to be associated with several side effects. There have been case reports about the associated sinus bradycardia with pulse dose corticosteroids administration both IV and oral. We present a case of asymptomatic sinus bradycardia associated with oral prednisone 40 mg. A 69-year-old male was admitted to the ICU for sepsis and subsequently was found to have gastrointestinal (GI) bleed. He developed an acute gout attack during hospitalization and was treated with prednisone 40 mg. Over the next 24 hours, the patient's heart rate dropped to 30s to 40s beats/minute while other vitals have remained stable. He was monitored on telemetry and review of the rhythm strips, as well as a 12-lead electrocardiogram (EKG), that showed sinus bradycardia; no pauses or atrio-ventricular (AV) nodal blocks were identified. The patient was not on any beta blocker or other therapies commonly associated with sinus bradycardia. His steroids were stopped while all other medications were continued. His heart rate slowly started to improve over the next 24 hours. He was not found to have any further episodes of bradycardia. Our case is unusual as we noted transient asymptomatic bradycardia with oral prednisone 40 mg dose. While bradycardia is reversible and may go unnoticed, it is important for the clinician to be aware of this adverse effect and include it in the list of potential differentials for bradycardia.

Clinical efficacy of high-dose dexamethasone with sequential prednisone maintenance therapy for newly diagnosed adult immune thrombocytopenia in a real-world setting

OBJECTIVE

As first-line treatments for newly diagnosed adult immune thrombocytopenia (ITP), high-dose dexamethasone (HD-DXM) and conventional-dose prednisone achieve good initial responses, but their long-term efficacy is poor. To improve the long-term outcome of newly diagnosed ITP, we explored the efficacy and safety of HD-DXM with sequential prednisone maintenance therapy.

METHODS

This retrospective study in a real-world setting assessed 72 consecutive newly diagnosed ITP patients administered first-line HD-DXM with sequential prednisone maintenance therapy from 1 June 2016 to 31 December 2019.

RESULTS

Seventy patients obtained response (97.2%), and 55 achieved sustained response (SR) (76.4%). Fifty-three obtained complete remission (CR) (73.6%), and 39 achieved continuous CR at 6 months (54.2%). Among 36 anti-nuclear antibody-positive patients, 100% achieved response, and 28 achieved CR (77.8%). Among 24 antithyroid antibody-positive patients, 23 (95.8%) achieved response, and 20 achieved CR (83.3%). For patients with initial response, the 12-month probability of SR was 78.6%. For patients with initial CR, the 12-month probability of continuous CR was 64.2%. At 12 months, 21.4% of patients with initial response and 11.3% of patients with initial CR showed loss of treatment response.

CONCLUSIONS

HD-DXM with sequential prednisone as the first-line treatment for newly diagnosed ITP patients may achieve good clinical efficacy.

Gender May Influence the Immunosuppressive Actions of Prednisone in Young Patients With Inflammatory Bowel Disease

Although the use of glucocorticoids (GC) is well established, the therapeutic response to these agents often shows important interindividual differences, in particular among young patients with inflammatory bowel diseases (IBD). Currently, GC resistance or dependence cannot be predicted by clinical or laboratory findings. The aim of this study was to investigate the association of gender and age with GC efficacy and with the expression of Glucocorticoid-Induced Leucine Zipper (GILZ). One hundred thirty patients (mean age at enrolment 12.6 years, 53 Crohn’s disease, 70 males) were enrolled in this retrospective study. IBD patients with active disease despite prednisone at a daily dose of up to 2 mg/kg over a period of 4 weeks were defined as steroid resistant. Patients who initially responded but relapsed upon dose reduction were considered steroid-dependent. Total RNA was extracted from biopsies of 14 patients (9 males) and the levels of GILZ mRNA were evaluated by real-time PCR. Association between clinical response to prednisone and the considered demographic variables was evaluated using logistic regression models. After 4 weeks of treatment, 112 patients were responders to prednisone and 18 were resistant; at this time-point, resistant patients were older than responders (p=0.032). After 12 weeks, 42, 71 and 12 patients were sensitive, dependent and resistant respectively; at this time-point, females were more prone than males to develop prednisone dependence vs a good response (p=0.028) while age had no effect. Age was associated with response both at 4 and 12 weeks in the subgroups of females: resistant patients were older than sensitive ones at 4 weeks (p=0.02). Likewise, at 12 weeks of therapy, dependent patients resulted older than sensitive ones (p=0.05). No association of age with prednisone response was found in males. In a subgroup of 14 patients (5 females), GILZ mRNA expression in intestinal biopsies was higher in males (p=0.0031). Patients with unfavorable response (7) presented lower GILZ expression at disease onset in comparison to the responder group (p=0.017). Older females with IBD have a higher incidence of prednisone unfavorable response and reduced intestinal expression of the GC pharmacodynamic marker GILZ.

The Effects of Prednisone/Ketoprofen Administration in Association with Amoxicillin Clavulanate Following Periodontal Surgical Therapy in Patients with Severe Chronic Periodontitis

Background and Objectives: The aim of this study was to evaluate and compare the effects of two different anti-inflammatory drugs (ketoprofen and prednisone) combined with an antibiotic (amoxicillin + clavulanic acid) and periodontal surgery on dental and periodontal parameters in patients with severe chronic periodontitis. In addition, salivary stress expressed by cortisol levels was assessed. Materials and Methods: An interventional study was performed on 22 periodontal subjects and 19 clinical healthy controls. The patients were divided in four groups, depending on treatment planning, as follows: eight patients received prednisone and antibiotherapy, associated with surgical periodontal therapy; seven patients received ketoprofen and antibiotherapy, associated with surgical periodontal therapy (group II); seven patients received only prednisone. Periodontal healthy patients underwent routine scaling and polishing. Bleeding on probing (BOP), dental mobility and salivary cortisol (ng/mL) were assessed before and after treatment. The means and standard deviations for the salivary cortisol levels (SCLs), dental and periodontal parameters were calculated for all groups using each patient as a unit of analysis. Results: Data analyses showed that the two different anti-inflammatory drugs associated with or without surgical therapy were efficient on inflammation periodontal parameters (BOP, dental mobility). Prednisone treatment alone was associated with a significant decrease of SCLs between pretreatment and post-treatment. Conclusions: In the present study, the effects of either of the anti-inflammatory drugs on inflammation evolution and salivary stress were comparable in patients undergoing antibiotherapy and surgical periodontal therapy.

An up-to-date evaluation of abiraterone for the treatment of prostate cancer

Introduction: Abiraterone acetate, an oral 17-alpha-hydroxylase inhibitor, effectively prevents the synthesis of androgens from steroid precursors. Abiraterone has become a standard of care in patients with metastatic prostate cancer due to its efficacy in both castrate-sensitive and castrate-resistant disease when given in combination with androgen deprivation therapy (ADT). Abiraterone may have a role in additional aspects of prostate cancer treatment in the future.Areas covered: The present article focuses on the development and establishment of abiraterone among the available treatment options for prostate cancer. A literature search was performed in PubMed/Medline for prior studies and reviews of the drug. Current clinical trials were examined in the Clinicaltrials.gov database.Expert opinion: Abiraterone has shown efficacy in castrate-resistant metastatic prostate cancer, providing an additional degree of hormonal sensitivity for tumors resistant to ADT. Impressively, abiraterone in conjunction with ADT as a first-line treatment for castrate-sensitive prostate cancer also confers a significant overall survival benefit compared to ADT alone. With minimal additional toxicity, abiraterone has established itself as a well-tolerated, convenient, and effective treatment option. Ongoing studies are expected to broaden the drug's indications as well as its preference among other prostate cancer therapies.

Subacute Thyroiditis and Heart Failure in a Patient Presenting With COVID-19

A 67-year-old male was admitted with shortness of breath and diarrhea. His COVID-19 polymerase chain reaction test was positive, and he was found to be in acute heart failure. Troponin levels were elevated, echocardiogram showed ejection fraction of 24%, and his electrocardiogram was normal. Inflammatory markers were elevated. Further testing revealed suppressed thyroid-stimulating hormone and elevated free thyroxine (T4). Differential diagnosis at this point included possible myocarditis from the viral illness, exacerbation of heart failure from the viral infection or from thyrotoxicosis was considered. Patient’s heart failure improved with initiation of heart failure therapies; however, biochemically, his thyroid function tests (TFTs) did not improve, despite empiric methimazole. Thyroid antibody tests were unremarkable. Thyroid ultrasound showed mildly enlarged thyroid gland with no increased vascularity and 5-mm bilateral cysts. Thyroid dysfunction was attributed to subacute thyroiditis from COVID-19, methimazole was tapered, and prednisone was initiated. The patient’s TFTs improved. With the ongoing COVID-19 pandemic, it is imperative that clinicians keep a broad differential in individuals presenting with heart failure, and obtaining baseline TFTs may be reasonable. Rapid treatment of the underlying thyroiditis is important in these patients to improve the cardiovascular outcomes. In our experience, steroid therapy showed a rapid improvement in the TFTs.

Prednisone reduction for metastatic castration-resistant prostate cancer with recurrent pulmonary tuberculosis: Case report

INTRODUCTION

Prednisone (10 mg/d) is often used in combination with docetaxel or abiraterone in the treatment of advanced prostate cancer. LATITUDE studies have confirmed that the combination of abiraterone and prednisone (5 mg/d) can be used for the treatment of newly diagnosed high-risk metastatic castration-sensitive prostate cancer, and have achieved satisfactory results. However, it has not been reported that abiraterone combined with prednisone (5 mg/d) in the treatment of metastatic castration-resistant prostate cancer (mCRPC).

PATIENT CONCERNS

Here, we present a case of high-risk advanced prostate cancer with old pulmonary tuberculosis (PTB). The patient developed a relapse of old tuberculosis in both lungs that were discovered following 14 months of continuous application of prednisone (10 mg/d).

DIAGNOSIS

The histopathological findings showed prostate adenocarcinoma carcinoma with a Gleason score of 10 (5+5). Further laboratory investigations were suggestive of positive mycobacterium tuberculosis complex DNA in pleural effusion and sputum.

INTERVENTIONS

The patient underwent endocrine therapy, chemotherapy of docetaxel plus prednisone, radiotherapy, and abiraterone combined with prednisone treatment, but he eventually developed into the mCRPC stage. Then, prednisone was reduced to 5 mg/d plus abiraterone, and combined with anti-tuberculosis treatment according to multi-disciplinary diagnosis and treatment.

OUTCOME

Two months later, pleural effusion and atelectasis were relieved, and PSA was remained stable at a low level. The patient achieved complete remission.

CONCLUSION

We cannot, with complete certainty, say that this patient, or any patient, developed old PTB recurrence due to the use of prednisone. Based on the current evidence, endocrine therapy is the foundation, radiotherapy can reduce the tumor load, and early application of abiraterone is beneficial to survival for the high-risk mCRPC. The long-term use of prednisone can be appropriately reduced in mCRPC with old PTB, and a satisfactory curative effect can be achieved. More prospective trials are warranted before a definite recommendation could be drawn.

Predicting the risk of relapse in polymyalgia rheumatica: novel insights

INTRODUCTION

Polymyalgia rheumatica (PMR) is a common inflammatory disease found in people older than 50 years of Northern European descent. It is characterized by pain and stiffness in the shoulders, arms, hips, and neck. Relapses are common in patients with PMR.

AREAS COVERED

This review describes when and how relapses occur in patients with PMR. Potential predisposing factors associated with relapses and management are also discussed. An extensive literature search on the PubMed database was conducted for publications on 'polymyalgia rheumatica' AND 'relapses' AND 'risk factors'.

EXPERT OPINION

Relapses are common in PMR being observed in approximately half of the patients. They often occur when the dose of prednisone is below 5-7.5 mg/day. The speed of glucocorticoid tapering is considered to be the main factor influencing the development of relapses in isolated PMRs. In addition, a genetic component may favor the presence of relapses in isolated PMRs. HLA-DRB1*0401 alleles were associated with an increased risk of relapse. An implication of the IL-6 promoter -174 G/C polymorphism and the GG241 ICAM-1 genotype  was also reported. With regard to serological biomarkers, elevated levels of angiopoietin-2 were associated with an unfavorable course of PMR. Methotrexate and anti-IL6 receptor antibody tocilizumab may be required in PMR patients with multiple relapses.

Update on diagnosis and treatment of immune thrombocytopenia

BACKGROUND

Immune thrombocytopenia (ITP) is a heterogeneous acquired disorder characterized by isolated thrombocytopenia whose exact pathogenesis is not yet clear. Depending upon the presence or absence of an underlying treatable cause, ITP can be categorized as primary or secondary. Primary ITP is a diagnosis of exclusion and there is no gold standard test for its confirmation. Recent drug intake, infections, lymphoproliferative disorders, and connective tissue disorders should be ruled out before labeling a patient as primary ITP.

AREA COVERED

This review summarizes a comprehensive update on the diagnostic and therapeutic modalities for ITP. We reviewed the literature using GOOGLE SCHOLAR, PUBMED and ClinicalTrial.gov databases as needed to support the evidence. We searched the literature using the following keywords: 'immune thrombocytopenia,' 'idiopathic thrombocytopenic purpura,' 'thrombocytopenia,' 'immune thrombocytopenic purpura,' and 'isolated thrombocytopenia'.

EXPERT OPINION

We believe that more detailed studies are required to understand the exact pathophysiology behind ITP. The first-line drugs like corticosteroids have both short-term and long-term adverse effects. This brings the need to explore effective alternative medications and to reconsider their role in ITP treatment algorithm if guidelines can be modified based on new studies.
