ABSTRACT

BACKGROUND: Thalidomide is the drug of choice for the treatment of type 2 leprosy reactions and is often associated with corticosteroids. The use of these drugs in multiple myeloma is associated with the risk of cardiovascular events, but there have been few studies assessing this risk in leprosy patients. OBJECTIVE: To evaluate the occurrence of cardiovascular events in patients with multibacillary leprosy and their correlation with the use of thalidomide and prednisone. METHODS: Analytical cross-sectional study of all patients diagnosed with multibacillary leprosy treated at the Dermatology Service between 2012 and 2022, using electronic medical records. Thromboembolic vascular events, both arterial and venous, including acute myocardial infarction, were considered. The main independent variable was the concomitant use of thalidomide and prednisone during follow-up. RESULTS: A total of 89 patients were included, of which 19 used thalidomide and prednisone concomitantly. There were five cardiovascular events (26.3%), three of which of deep venous thrombosis. The combined use of medications was associated with the events (PR=6.46 [3.92 to 10.65]; p<0.01). STUDY LIMITATIONS: Small number of events, single-center retrospective study. CONCLUSION: The hypothesis of an association between cardiovascular events and the concomitant use of thalidomide and prednisone is supported, but more robust prospective studies are required for a better assessment.

ABSTRACT

PURPOSE: This is a retrospective, single-center PSM study evaluating the efficacy and safety of chidamide combined with the CHOEP (C-CHOEP) regimen versus the single CHOEP regimen in patients with untreated peripheral T cell lymphomas (PTCL). PATIENTS: Patients newly diagnosed with PTCL between January 2015 and June 2021 were recruited, and were 1:1 divided into C-CHOEP and CHOEP groups according to their first-line chemotherapy regimens. The PSM method was used to match the baseline variables to balance the confounding factors. RESULTS: A cohort of 33 patients each in the C-CHOEP and CHOEP groups was generated after propensity score-matching (PSM). The complete remission (CR) rates of the C-CHOEP regimen were higher than that of the CHOEP regimen (56.3 vs. 25.8%, p = 0.014), whereas the duration of response of the C-CHOEP group was shorter (median DOR 30 vs. 57 months), resulting in roughly similar progression-free survival (PFS) and (overall survival) OS between the two groups. The responding patients who received chidamide maintenance therapy showed a trend of superior PFS and OS compared with patients who did not receive maintenance therapy. CONCLUSIONS: The C-CHOEP regimen was well tolerated but failed to show advantages over the CHOEP regimen in patients with untreated PTCL; however, the chidamide maintenance may contribute to a more durable response and stable long-term survival.

ABSTRACT

La osteonecrosis múltiple es una entidad poco frecuente que se define por el compromiso de al menos tres regiones diferentes. Es indispensable el abordaje multidisciplinario de los pacientes que la padecen tanto para el diagnóstico como el tratamiento oportuno. Presentamos el caso clínico de un paciente joven que presenta una osteonecrosis múltiple con compromiso de ambas caderas, hombros, rodillas, codo derecho y cuello de pie izquierdo. El principal factor de riesgo presente en nuestro caso es el consumo de glucocorticoides.


Multiple osteonecrosis is a rare entity that is defined by the involvement of at least three different regions. A multidisciplinary approach to patients who suffer from it is essential for both diagnosis and timely treatment. We present the clinical case of a young patient who presented multiple osteonecrosis with involvement of both hips, shoulders, knees, right elbow, and neck of the left foot. The main risk factor present in our case is the consumption of glucocorticoids.

ABSTRACT

PURPOSE: Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma subtype. The purpose of this study was to evaluate the clinical features, prognostic factors, and results of DLBCL that was treated in the cancer centers of the public health system in Chile and compare cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) with rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). PATIENTS AND METHODS: Patients age > 15 years who were treated in 18 cancer centers in the country between 2001 and 2017 were included. The Kaplan-Meier method was used to calculate overall survival (OS), and Cox proportional hazard regression modeling was used to evaluate the effect of the addition of rituximab to CHOP on OS. RESULTS: A total of 1,807 patients were evaluated. The median age at diagnosis was 62 (range, 15-95) years, with a female predominance (53%). Half of the patients were age ≥ 60 years. Serology for HIV infection was positive in 5% of cases (96 cases). International Prognostic Index scores were available for 90% of patients, of which 45% had low-risk, 25% low-intermediate-risk, 18% high-intermediate-risk, and 11% high-risk scores. CHOP was administered to 986 patients (55%; median follow-up, 13.2 years) and R-CHOP to 821 patients (45%; median follow-up, 8.4 years). R-CHOP was associated with superior OS compared with CHOP (5-year 66% v 48%, and 10-year 53% v 35%; P < .001). CONCLUSION: Rituximab improved the survival of patients with DLBCL diagnosed and treated in Chile. The benefit was sustained over time, with curative rates of > 50%. This intervention shows that the inclusion of this biological drug justified the expenses incurred by the Ministry of Health in the National Lymphoma Protocols in Chile.

ABSTRACT

BACKGROUND: Nodal peripheral T-cell lymphoma (nPTCL) constitute a heterogeneous group of neoplasms with aggressive behavior and poor-survival. They are more prevalent in Latin America and Asia, although data from Brazil are scarce. Its primary therapy is still controversial and ineffective. Therefore, we aim to describe clinical-epidemiological characteristics, outcomes, predictors factors for survival and compare the results of patients treated with CHOP and CHOEP regimens. METHODS: Retrospective, observational and single-center study involving 124 nPTCL patients from Brazil treated from 2000 to 2019. RESULTS: With a median follow-up of 23.7 months, the estimated 2-year overall survival (OS) and progression-free survival (PFS) were 59.2% and 37.3%, respectively. The median age was 48.5 years and 57.3% (71/124) were male, 81.5% (101/124) had B-symptoms, 88.7% (110/124) had advanced disease (stage III/IV) and 58.1% (72/124) presented International Prognostic Index (IPI) score ≥3, reflecting a real-life cohort. ORR to first-line therapy was 58.9%, 37.9% (N = 47) received CHOP-21 and 35.5% (N = 44) were treated with CHOEP-21; 30.1% (37/124) underwent to consolidation with involved field radiotherapy (IF-RT) and 32.3% (40/124) were consolidated with autologous hematopoietic stem cell transplantation (ASCT). The overall response rate (ORR) was similar for CHOP-21 (76.6%) and CHOEP-21 (65.9%), P = .259. Refractory disease was less frequent in the CHOEP-21 group (4.5% vs. 21.2%, P = .018). However, few patients were able to complete 6-cycles of CHOEP-21 (31.8%) than to CHOP-21 (61.7%), P = .003. Delays ≥2 weeks among the cycles of chemotherapy were more frequent for patients receiving CHOEP-21 (43.1% vs. 10.6%), P = .0004, as well as the toxicities, including G3-4 neutropenia (88% vs. 57%, P = .001), febrile neutropenia (70% vs. 38%, P = .003) and G3-4 thrombocytopenia (63% vs. 27%, P = .0007). The 2-year OS was higher for CHOP (78.7%) than CHOEP group (61.4%), P = .05, as well as 2-year PFS (69.7% vs. 25.0%, P < .0001). In multivariate analysis, high LDH (HR 3.38, P = .007) was associated with decreased OS. CR at first line (HR: 0.09, P < .001) and consolidation with ASCT (HR: 0.08, P = .015) were predictors of increased OS. CONCLUSION: In the largest cohort of nPTCL from Latin America, patients had poor survival and high rate of chemo-resistance. In our cohort, the addition of etoposide to the CHOP-21 backbone showed no survival benefit and was associated with high-toxicity and frequent treatment interruptions. Normal LDH values, obtaintion of CR and consolidation with ASCT were independent factors associated with better outcomes.

ABSTRACT

OBJECTIVES: We aimed to study the daily dose of glucocorticoids in the first month associated with damage after 5 years of systemic lupus erythematosus (SLE) diagnosis; and to assess the daily dose of prednisone during the first year, over which damage after 5 years could be predicted. METHODOLOGY: A retrospective cohort study of SLE patients from the diagnosis and up to 5 years of follow-up was performed. Cumulative prednisone doses in the first month (T1m), at 1 year (T12m), and at 5 years (T5y) were calculated. Damage was estimated using the SLICC index and activity by the SLEDAI-2K. Damage at T5y was categorized as "present" or "absent". To determine the cutoff point of prednisone dose for the first month and for the first year of treatment, related to damage at 5 years, a ROC curve was done. A logistic regression was performed to control damage at 5 years by the activity levels, anti-DNA titers, and the corticosteroid burden between 1 and 5 years. RESULTS: Forty-eight patients were included with a mean age of 42.4 (12.6) years; 46 (95.8%) were female. The cumulative dose in T1m associated with greater sensitivity and specificity in the ROC curve (1.54; AUC 0.793; 95% CI: 0.66-0.92) to predict glucocorticoid-related damage at 5 years of follow-up was 980mg, which leads to a daily dose for the first month of 32.6 mg/day. The daily dose during the first year associated with damage at 5 years, allowed to calculate an optimal cutoff point of 7.38 mg/day, with a sensitivity of 92.9% (AUC 0.695, 95% CI: 0.52-0.86) to predict damage at 5 years. In the logistic regression, this estimate was maintained, controlling for SLEDAI-2K and for positivity or not of anti-DNA antibodies and for the cumulative dose of prednisone between T5y and T12m. CONCLUSION: This pilot study allows to estimate a threshold dose of 32.6 mg/day during the first month and 7.38 mg/day during the first year, over which the risk of permanent damage is high at 5 years, regardless of the activity levels and the glucocorticoid doses considered between the first and the fifth year of follow-up.

ABSTRACT

Mast cell tumors (MCTs) are common neoplasms in dogs, and treatments for these diseases include surgery, polychemotherapy and targeted therapy with tyrosine kinase inhibitors. This study aimed to evaluate the response and the adverse events of treatment with imatinib mesylate (IM) compared to conventional therapy using vinblastine and prednisolone (VP) in canine cutaneous MCTs. Twenty-four dogs were included in the study; 13 animals were treated with IM and 11 with VP. Tumor tissue samples were submitted for histological diagnosis, grading and KIT immunostaining. The response to treatment was assessed by tomographic measurements according to VCOG criteria. Adverse events were classified according to VCOG-CTCAE criteria. The IM and VP groups had dogs with similar breeds, gender, ages, MCT localization, WHO stages and lymph node metastasis profiles. Most MCTs were grade 2/low and had KIT- patterns 2 and 3. The objective response rate (ORR) was significantly higher (30.79%) in the IM group then in VP group (9.09%). Adverse events (AE) in IM group were all grade 1, significantly different from VP. In conclusion, IM presented better ORR and less severe adverse events when compared to VP, representing a suitable option for the treatment of low-grade canine MCTs.

ABSTRACT

OBJECTIVE: To systematically describe the short stature of patients with Diamond-Blackfan anemia and to explore factors affecting the height development of patients with Diamond-Blackfan anemia. STUDY DESIGN: This cross-sectional study was conducted at the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, and the height, weight, and clinical data of 129 patients with Diamond-Blackfan anemia were collected from June 2020 to September 2020. RESULTS: The median height-age-z score (HAZ) of children affected by Diamond-Blackfan anemia was -1.54 (-6.36-1.96). Short stature was found in 37.98% of the patients. Specific Diamond-Blackfan anemia growth curves were developed for weight, height, and body mass index, separately for male and female patients. Multivariable logistic regression models showed that female sex (aOR 4.92; 95% CI 1.29-18.71; P = .0195), underweight (aOR 10.41, 95% CI 1.41-76.98, P = .0217), cardiovascular malformations (aOR 216.65; 95% CI 3.29-14279.79; P = .0118), and RPL11(aOR 29.14; 95% CI 1.18-719.10; P = .0392) or RPS26 (aOR 53.49; 95% CI 1.40-2044.30; P = .0323) mutations were independent risk factors for short stature. In the subgroup of patients who were steroid-dependent, patients with a duration of steroid therapy over 2 years (OR 2.95; 95% CI 1.00-8.66; P = .0494) or maintenance dose of prednisone >0.1 mg/kg per day (OR 3.30; 95% CI 1.02-10.72; P = .0470) had a higher incidence of short stature. CONCLUSIONS: Patients with Diamond-Blackfan anemia had a high prevalence of short stature. The risk of short stature increased with age and was associated with sex, underweight, congenital malformations, and RPL11 or RPS26 mutations. The duration of steroid therapy and maintenance dose of steroid was significantly associated with the incidence of short stature in steroid-dependent patients with Diamond-Blackfan anemia.

ABSTRACT

Prednisone (PD) is one of the most commonly used corticosteroids in immunosuppressive therapy for patients with autoimmune diseases and transplants. Chronic use of corticosteroids is associated with several side effects and an increase in neoplasia. Since genotoxic effects are associated with an increased risk of cancer development, this study evaluated the genotoxic and cytotoxic activities of PD using the SMART/wing assay in Drosophila melanogaster and the micronucleus test and comet assay in mouse bone marrow cells. Further, the toxic effects of PD on mouse organ tissues were assessed using histopathological analyses. In the SMART/wing assay, PD showed a significant genotoxic activity at all concentrations tested (0.375, 0.75, 1.5, and 2.0 mg/mL) compared to the negative control (p < 0.05). The micronucleus test and comet assay also showed an elevated genotoxicity of PD at all treatment conditions (24, 48, and 120 h with doses ranging from 0.5 to 1.5 mg/kg) compared to the negative control (p < 0.05). The histopathological analyses did not show toxicity of PD in mouse cells and tissues. Therefore, our results demonstrate that PD is a potent genotoxic immunosuppressant in mice and D. melanogaster cells. Somatic recombination was the primary contributor (46%-82%) to the induced genotoxicity observed in the SMART test.

ABSTRACT

PURPOSE: Considering the increased cancer patient survivorship, the focus is now on addressing the impacts of treatment on quality of life. In young people, altered reproductive function is a major issue and its effects in young males are largely neglected by novel research. To improve clinician awareness, we systematically reviewed side effects of chemotherapy for Hodgkin lymphoma (HL) in young males. METHODS: The review was prospectively registered (PROSPERO N. CRD42019122868). Three databases (Medline via PUBMED, SCOPUS, and Cochrane Library) were searched for studies featuring males aged 13-51-years who underwent chemotherapy for HL using ABVD (Adriamycin® (doxorubicin), bleomycin, vinblastine, and dacarbazine) or BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisolone) regimens. These chemotherapy regimens were compared against each other using sperm characteristics, FSH, and inhibin B levels to measure fertility levels. RESULTS: Data were extracted from five studies featuring 1344 patients. 6 months post-ABVD saw marked deterioration in sperm count, further reduced by more cycles (P = 0.05). Patients treated with BEACOPP rather than ABVD were more prone to oligospermia. Receiving fewer cycles of both regimens increased the likelihood of sperm production recovering. Patients treated with 6-8 cycles of BEACOPP did not recover spermiogenesis. CONCLUSIONS: ABVD and BEACOPP regimens significantly reduce fertility function to varying effects depending on treatment duration. ABVD temporarily causes significant reductions in male fertility, whereas BEACOPP's effects are more permanent. Therefore, clinicians should discuss fertility preservation with male patients receiving infertility-inducing gonadotoxic therapy. Further high-quality studies are required to more adequality describe the risk to fertility by chemotherapy.

ABSTRACT

OBJECTIVE: The American Academy of Ophthalmology recommends a maximum hydroxychloroquine (HCQ) dose of ≤5.0 mg/kg/day to reduce the risk of HCQ-induced retinopathy. To determine if this dose adjustment would have an impact on the clinical course of SLE, we compared outcome measures in a cohort of patients with SLE before and after adjusting HCQ dose. METHODS: Sixty Puerto Ricans with SLE (per 1997 American College of Rheumatology criteria) treated with HCQ who were changed to HCQ ≤5.0 mg/kg/day were studied. Visits were ascertained every 6 months for 2 years before and 2 years after HCQ dose adjustment (baseline visit). Disease activity (per Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)), SLE exacerbations, emergency room visits, hospitalisations, disease damage (per Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index), corticosteroids exposure, prednisone dose and immunosuppressive drugs exposure were determined before and after HCQ dose change. RESULTS: At baseline visit, the mean age was 43.8±15.1 years. All patients were women. The mean disease duration was 13.8±9.1 years. After HCQ dose adjustment, patients required a lower prednisone dose when compared with visits before HCQ dose reduction. No significant differences were observed for mean SLEDAI scores, lupus exacerbations, emergency room visits, hospitalisations, disease damage and exposure to immunosuppressive drugs before and after HCQ dose adjustment. CONCLUSIONS: This study suggests that adjustment of daily HCQ dose to ≤5.0 mg/kg/day of actual body weight does not have a significant impact on the short-term and mid-term outcomes in this group of patients with SLE.

ABSTRACT

Abstract Tolosa-Hunt syndrome is a painful ophthalmoplegia caused by non-specific granulomatous inflammation, corticoid-sensitive, of the cavernous sinus. The etiology is unknown. Recurrences are common. The diagnosis is made by exclusion, and a variety of other diseases involving the orbital apex, superior orbital fissure and cavernous sinus should be ruled out. This study reports a case of a 29-year-old woman, diagnosed with Tolosa-Hunt Syndrome, who presented ophthalmoparesis and orbital pain. She had poor response to corticotherapy and developed colateral effects, so she was treated with single infliximab dose immunosuppression, evolving total remission of the disease.


Resumo A Síndrome de Tolosa-Hunt é uma oftalmoplegia dolorosa causada por uma inflamação granulomatosa não específica, sensível a corticoides, do seio cavernoso. A etiologia é desconhecida. Recorrências são comuns. O diagnóstico é feito por exclusão, devendo ser descartada uma variedade de outras doenças que envolvem o ápice orbitário, fissura orbitária superior e seio cavernoso. O presente estudo trata-se de um relato de caso de uma paciente de 29 anos, diagnosticada com Síndrome de Tolosa-Hunt, que apresentou paresia e dor em região orbital. Obteve resposta pouco efetiva a corticoterapia e desenvolveu efeitos colaterais, por isso foi tratada com dose única de infliximabe, evoluindo com remissão total da doença.

ABSTRACT

The relationship between parasites and glomerulonephritis (GN) is well documented in certain parasitoses, but not in cases of Strongyloides stercolaris (S. stercolaris) where there are few cases described being the majority GN of minimal changes. We report a case of hyperinfestation by S. stercolaris in a patient affected by a membranous GN treated with oral corticosteroids with fatal outcome for the patient. This case provides a double teaching: first about a rare association of strongyloid and membranous GN and second about the importance of establishing a diagnosis of suspected and appropriate treatment for certain infections or diseases with little clinical expression before starting any immunosuppressive treatment.

ABSTRACT

BACKGROUND: Limited studies have been carried out with prednisone (PRED) in treatment by glucose intolerant individuals, even in this model the animals presented low blood glucose levels at adulthood, by the high regenerative capacity of ß-cell. OBJECTIVE: The aim was to evaluate the effects of the treatment of PRED in mild diabetes on biochemical and immunological biomarkers. METHODS: Rats were randomly divided into four groups: control (C), treated control C+PRED (treatment of 1.25 mg/Kg/day PRED); diabetic DM (mild diabetes) and treated diabetic DM+PRED (treatment with same dose as C+PRED group). Untreated groups received vehicle, adjusted volume to body weight. The treatment lasted 21 days and measured body weight, food and water intake, and glycemia weekly. In the 3rd week, the Oral Glucose Tolerance Test (OGTT) and the Insulin Tolerance Test (ITT) was performed. On the last day, the rats were killed and the blood was collected for biochemical analyzes, leukogram and immunoglobulin G levels. RESULTS: There was a significant decrease in body weight in mild diabetes; however, the treatment in diabetic groups increased food intake, glycemia, and the number of total leukocytes, lymphocytes and neutrophils. On the other hand, it decreased the levels of triglycerides, high-density and very lowdensity lipoproteins. In addition, diabetic groups showed glucose intolerance and mild insulin resistance, confirming that this model induces glucose intolerant in adult life. CONCLUSION: The results showed that the use of prednisone is not recommended for glucose intolerant individuals and should be replaced in order to not to aggravate this condition.

ABSTRACT

BACKGROUND: Standard-of-care treatment for patients with newly diagnosed multiple myeloma includes combination therapies for patients who are not eligible for autologous stem-cell transplantation. At the primary analysis for progression-free survival of the phase 3 ALCYONE trial, progression-free survival was significantly longer with daratumumab in combination with bortezomib, melphalan, and prednisone (D-VMP) versus bortezomib, melphalan, and prednisone (VMP) alone in patients with transplant-ineligible, newly diagnosed multiple myeloma. Here we report updated efficacy and safety results from a prespecified, interim, overall survival analysis of ALCYONE with more than 36 months of follow-up. METHODS: ALCYONE was a multicentre, randomised, open-label, active-controlled, phase 3 trial that enrolled patients between Feb 9, 2015, and July 14, 2016, at 162 sites in 25 countries across North America, South America, Europe, and the Asia-Pacific region. Patients were eligible for inclusion if they had newly diagnosed multiple myeloma and were ineligible for high-dose chemotherapy with autologous stem-cell transplantation, because of their age (≥65 years) or because of substantial comorbidities. Patients were randomly assigned in a 1:1 ratio and by permuted block randomisation to receive D-VMP or VMP. An interactive web-based randomisation system was used. Randomisation was stratified by International Staging System disease stage, geographical region, and age. There was no masking to treatment assignments. All patients received up to nine 6-week cycles of subcutaneous bortezomib (1·3 mg/m2 of body surface area on days 1, 4, 8, 11, 22, 25, 29, and 32 of cycle one and on days 1, 8, 22, and 29 of cycles two through nine), oral melphalan (9 mg/m2 once daily on days 1 through 4 of each cycle), and oral prednisone (60 mg/m2 once daily on days 1 through 4 of each cycle). Patients in the D-VMP group also received intravenous daratumumab (16 mg/kg of bodyweight, once weekly during cycle one, once every 3 weeks in cycles two through nine, and once every 4 weeks thereafter as maintenance therapy until disease progression or unacceptable toxicity). The primary endpoint was progression-free survival, which has been reported previously. Results presented are from a prespecified interim analysis for overall survival. The primary analysis population (including for overall survival) was the intention-to-treat population of all patients who were randomly assigned to treatment. The safety population included patients who received any dose of study treatment. This trial is registered with ClinicalTrials.gov, NCT02195479. FINDINGS: 706 patients were randomly assigned to treatment groups (350 to the D-VMP group, 356 to the VMP group). At a median follow-up of 40·1 months (IQR 37·4-43·1), a significant benefit in overall survival was observed for the D-VMP group. The hazard ratio (HR) for death in the D-VMP group compared with the VMP group was 0·60 (95% CI 0·46-0·80; p=0·0003). The Kaplan-Meier estimate of the 36-month rate of overall survival was 78·0% (95% CI 73·2-82·0) in the D-VMP group and 67·9% (62·6-72·6) in the VMP group. Progression-free survival, the primary endpoint, remained significantly improved for the D-VMP group (HR 0·42 [0·34-0·51]; p<0·0001). The most frequent adverse events during maintenance daratumumab monotherapy in patients in the D-VMP group were respiratory infections (54 [19%] of 278 patients had upper respiratory tract infections; 42 [15%] had bronchitis, 34 [12%] had viral upper respiratory tract infections), cough (34 [12%]), and diarrhoea (28 [10%]). INTERPRETATION: D-VMP prolonged overall survival in patients with newly diagnosed multiple myeloma who were ineligible for stem-cell transplantation. With more than 3 years of follow-up, the D-VMP group continued to show significant improvement in progression-free survival, with no new safety concerns. FUNDING: Janssen Research & Development.

ABSTRACT

Paracoccidioidomycosis is a fungal infection that occurs in immunocompetent patients and are classified into two forms: the acute-subacute form, predominantly in young patients, and the chronic adult form that may present classic ulcerated lesions to rare sarcoid ones. We present the case of a boy whose infection began with sarcoid lesions but, after being mistakenly diagnosed with cutaneous sarcoidosis and treated (for three years) with prednisone, developed painful ulcerations throughout the body. After the correct diagnosis, with evidence of the fungus in histopathological and mycological examinations, the patient was properly treated with itraconazole for eight months and evolved with total remission of the disease.

ABSTRACT

Aim: To evaluate the effects of gene polymorphisms in the treatment of erythema nodosum leprosum with prednisone/thalidomide. Patients & methods: A total of 152 patients from different regions of Brazil were included. Generalized estimating equation was used to evaluate the influence of polymorphisms and haplotypes on the drug dose variation throughout the treatment. Results: An association between the genotype tuberculoid of polymorphism ABCB1 3435C>T (rs1045642; p = 0.02) and prednisone dose was found in the recessive model. An association between the haplotypes 1031T/-863C/-857C/-308A/-238G (p = 0.006) and 1031T/-863C/-857T/-308A/-238G (p = 0.040) of the TNF gene and the CYP2C19*2 polymorphism were also identified, in relation to thalidomide dosage variation over the course of treatment. Conclusion: This work presents the first pharmacogenetic report of association between gene polymorphisms and erythema nodosum leprosum treatment with prednisone/thalidomide.

ABSTRACT

BACKGROUND: Recommendations of the Myopathy Committee of the Brazilian Society of Rheumatology for the management and therapy of systemic autoimmune myopathies (SAM). MAIN BODY: The review of the literature was done in the search for the Medline (PubMed), Embase and Cochrane databases including studies published until June 2018. The Prisma was used for the systematic review and the articles were evaluated according to the levels of Oxford evidence. Ten recommendations were developed addressing the management and therapy of systemic autoimmune myopathies. CONCLUSIONS: Robust data to guide the therapeutic process are scarce. Although not proven effective in controlled clinical trials, glucocorticoid represents first-line drugs in the treatment of SAM. Intravenous immunoglobulin is considered in induction for refractory cases of SAM or when immunosuppressive drugs are contra-indicated. Consideration should be given to the early introduction of immunosuppressive drugs. There is no specific period determined for the suspension of glucocorticoid and immunosuppressive drugs when individually evaluating patients with SAM. A key component for treatment in an early rehabilitation program is the inclusion of strength-building and aerobic exercises, in addition to a rigorous evaluation of these activities for remission of disease and the education of the patient and his/her caregivers.

ABSTRACT

OBJECTIVE: To assess if the use of a dose-dense regimen of chemotherapy can improve the prognosis in patients with primary gastric diffuse large B-cell lymphoma in early stages (I-II) but associated with worse prognostic factors. METHODS: One hundred and eight consecutive patients with primary gastric diffuse large B-cell lymphoma in early stages (I-II) with high serum levels of lactic dehydrogenase and beta 2 microglobulin (more than >2 of normal levels), which were associated with a worse prognostic outcome, were treated with a dose-dense chemotherapy: CHOP with increased doses of cyclophosphamide and doxorubicin, was administered every 14 days (instead of 21 days). The end points of this study were to improve outcome measured from progression-free survival and overall survival and to evaluate acute toxicities. RESULTS: Complete response was achieved in 85 patients (78%). Actuarial curves at five years show that progression-free survival was 82% and overall survival was 85%. Hematological toxicities were severe, but no death-related treatment was observed. CONCLUSIONS: We considered that in this setting of patients, the use of a dose-dense regimen could be of benefit because it improves outcome and toxicities were well controlled.
