Eficacia y seguridad del calcipotriol y el dipropionato de betametasona en pacientes adultos con psoriasis vulgar en placas moderada o severa, no respondedores a la terapia tópica y sistémica convencional, y no tributarios a terapia biológica / Efficacy and safety of calcipotriol and betamethasone dipropionate in adult patients with moderate or severe plaque psoriasis vulgaris, unresponsive to conventional topical and systemic therapy, and not amenable to biological therapy

ANTECEDENTES: En el marco de la metodología ad hoc para evaluar solicitudes de tecnologías sanitarias, aprobada mediante Resolución de Institución de Evaluación de Tecnologías en Salud e Investigación N° 111-IETSI-ESSALUD-2021, se ha elaborado el presente dictamen que expone la evaluación de la eficacia y seguridad del calcipotriol y dipropionato de betametasona (DB) en pacientes adultos con psoriasis vulgar en placas moderada o severa, no respondedores a la terapia tópica y sistémica convencional, y no tributarios a terapia biológica. Así, la médico dermatóloga, Dra. Lorraine Lía Málaga Medina del Servicio de Dermatología del Hospital Nacional Carlos Seguin Escobedo, siguiendo la Directiva N.° 003-IETSI-ESSALUD-2016, envió al Instituto de Evaluación de Tecnologías en Salud e Investigación - IETSI la solicitud de uso por fuera del petitorio farmacológico de EsSalud el producto farmacéutico calcipotriol en combinación con el (DB), para el tratamiento de los pacientes adultos con psoriasis vulgar en placas moderada o severa, no respondedores a la terapia tópica y sistémica convencional, y no tributarios a terapia biológica. ASPECTOS GENERALES: La psoriasis vulgar en placas es una enfermedad crónica de la piel que se presenta como placas eritematosas y escamosas que aparecen, mayoritariamente, en el cuero cabelludo, el tronco, los glúteos, y los miembros inferiores y superiores (de Rie et al., 2004). Esta enfermedad es considerada como un problema de salud pública por su alta prevalencia, alto riesgo de morbilidad y porque deteriora la calidad de vida y salud mental en los pacientes que la padecen (Boehncke & Schón, 2015). La psoriasis afecta del 1 % al 3 % de la población mundial; y la psoriasis vulgar en placas representa hasta el 90 % de todas las manifestaciones de la psoriasis (Augustin et al., 2010). Además, la presencia de esta enfermedad se asocia a mayor riesgo de sufrir artritis psoriásica, enfermedades cardiovasculares, diabetes mellitus, obesidad, enfermedad del hígado graso no alcohólico y enfermedades inflamatorias del intestino (Gisondi et al., 2020). Asimismo, el 75 % de estos pacientes percibe un deterioro en su calidad de vida y cerca del 10 % ha tenido ideación suicida (Bhosle et al., 2006). METODOLOGÍA: Se llevó a cabo una búsqueda bibliográfica exhaustiva con el objetivo de identificar la mejor evidencia disponible sobre la eficacia y seguridad del CAL-DB, en comparación con mejor terapia de soporte, en pacientes adultos con psoriasis vulgar en placas moderada o severa no respondedores a la terapia tópica y sistémica convencional y no tributarios a terapia biológica. La búsqueda se realizó en las bases de datos bibliográfica de PubMed, The Cochrane Library y LILACS. Asimismo, se realizó una búsqueda manual dentro de las páginas web pertenecientes a grupos que realizan evaluación de tecnologías sanitarias (ETS) y guías de práctica clínica (GPC) incluyendo el National Institute for Health and Care Excellence (NICE), la Agency for Healthcare Research and Quality's (AHRQ), la Scottish I ntercollegiate Guidelines Network (SIGN), la New Zealand Guidelines Group (NZGG), la National Health and Medical Research Council (NHMRC), el Instituto de Evaluación de Tecnologías en Salud e Investigación (IETSI), el Centro Nacional de Excelencia Tecnológica en Salud (CENETEC), la Canadian Agency for Drugs and Technologies in Health (CADTH), el Institute for Quality and Efficiency in Health Care (IQWIG), el Scottish Medicines Consortium (SMC), la Comissáo Nacional de I ncorpornáo de Tecnologías no Sistema Único de Saúde (CONITEC), el Instituto de Evaluación Tecnológica en Salud (IETS) y el Instituto de Efectividad Clínica y Sanitaria (IECS). Finalmente, se realizó una búsqueda adicional en la página web de registro de ensayos clínicos (EC) www.clinicaltrials.gov, para identificar EC en curso o aún no publicados. RESULTADOS: Tras ampliar los criterios de selección de documentos, se incluyó una GPC publicada por el NICE (2012) que realiza recomendaciones sobre la evaluación y el tratamiento de pacientes con psoriasis vulgar de severidad moderada o severa. Además, se incluyeron dos ETS publicadas por la CONITEC (2012), y la HAS (2019) que tuvieron como objetivo evaluar la evidencia disponible acerca de la eficacia y seguridad del uso del Cal-DB en pacientes adultos con psoriasis vulgar en placas e incluyeron, en su cuerpo de evidencia, ECA donde participaron pacientes con psoriasis vulgar de severidad moderada a severa. También, se incluyó el estudio pivotal citado en la ficha técnica del Daivobet ® aprobada por DIGEMID (2018), el cual es un ECA de fase II que comparó la eficacia y seguridad del uso del CAL-DB versus el calcipotriol en monoterapia, el DB en monoterapia y placebo, en pacientes con psoriasis vulgar de cualquier severidad de enfermedad (Fleming et al., 2010). Por último, se incluyó un estudio observacional que comparó el uso de la fototerapia y el CAL-DB en pacientes con severidad de enfermedad de moderada a severa (Polanska et al., 2019). ONCLUSIÓN: Por lo expuesto, el Instituto de Evaluación de Tecnologías en Salud e Investigación no aprueba el uso combinado del calcipotriol y el dipropionato de betametasona en pacientes adultos con psoriasis vulgar moderada o severa, no respondedores a la terapia tópica y sistémica convencional y no tributarios a terapia biológica, como producto farmacéutico no incluido en el Petitorio Farmacológico de EsSalud.

Comparative Effectiveness and Safety of Different Types of Inhaled Long-Acting ß2-Agonist Plus Inhaled Long-Acting Muscarinic Antagonist vs Inhaled Long-Acting ß2-Agonist Plus Inhaled Corticosteroid Fixed-Dose Combinations in COPD A Propensity Score-Inverse Probability of Treatment Weighting Cohort Study.

BACKGROUND: Despite multiple available fixed-dose combinations (FDCs) of inhaled long-acting ß2-agonists (LABAs) plus long-acting muscarinic antagonists (LAMAs) and LABAs plus inhaled corticosteroids (ICS) for COPD, uncertainty remains regarding their comparative effects. RESEARCH QUESTION: Can comparative effectiveness and safety of LABA plus LAMA (LABA/LAMA) and LABA plus ICS (LABA/ICS) FDCs vary by different individual components of the dual combinations in COPD? STUDY DESIGN AND METHODS: We conducted a new user, propensity score-inverse probability of treatment weighting cohort study to compare the effectiveness and safety of two frequently used LABA/LAMA FDCs (indacaterol plus glycopyrronium [IND/GLY] and vilanterol plus umeclidinium [VI/UMEC]) vs three commonly prescribed LABA/ICS FDCs (salmeterol plus fluticasone propionate [SAL/FP], formoterol fumarate plus budesonide [FF/BUD], and formoterol fumarate plus beclomethasone dipropionate [FF/BDP]) using the Taiwanese nationwide health care claims from 2014 through 2017. The primary effectiveness outcome was the annual moderate to severe exacerbation rate, and safety outcomes included risks of severe pneumonia and cardiovascular disease requiring hospitalization. Weighted generalized linear mixed models and Cox proportional hazard models were used to assess the effectiveness and safety outcomes, respectively. RESULTS: Patients with COPD initiating IND/GLY and VI/UMEC showed an 11% (incidence rate ratio [IRR], 0.89; 95% CI, 0.80-0.98) and 20% (IRR, 0.80; 95% CI, 0.71-0.90) reduced annual rate of moderate to severe exacerbations, respectively, than those initiating SAL/FP, but showed a similar rate as those initiating FF/BUD or FF/BDP. Both LABA/LAMA FDCs, compared with SAL/FP and VI/UMEC vs FF/BDP, were associated with a 27% (hazard ratio [HR], 0.73; 95% CI, 0.59-0.90) to 42% (HR, 0.58; 95% CI, 0.48-0.70) reduced pneumonia risk. Cardiovascular risk was comparable in five groups. An intraclass difference existed in rates of moderate to severe COPD exacerbation and risks of pneumonia among LABA/ICS FDCs, but not between LABA/LAMA FDCs. INTERPRETATION: Both LABA/LAMAs vs SAL/FP are associated with a lower exacerbation rate and pneumonia risk, but exhibit similar effectiveness and safety outcomes compared with FF/BDP or FF/BUD, suggesting that comparative effects may differ by individual components of the dual therapies in COPD.

Beclomethasone dipropionate, formoterol fumarate and glycopyrronium bromide: Synergy of triple combination therapy on human airway smooth muscle ex vivo.

BACKGROUND AND PURPOSE: Combining inhaled corticosteroids (ICSs), long-acting ß2 -adrenoceptor agonists (LABAs) and long-acting muscarinic antagonists (LAMAs) is recommended to treat severe forms of asthma and chronic obstructive pulmonary disease (COPD). Clinical benefits have been demonstrated for ICS/LABA/LAMA combinations. This study characterized the interaction between the ICS beclomethasone dipropionate, the LABA formoterol fumarate and the LAMA glycopyrronium bromide in human airways. EXPERIMENTAL APPROACH: Human passively sensitized airways and bronchi from COPD donors were stimulated with histamine or carbachol. Tissues were incubated overnight with beclomethasone and then treated with formoterol and glycopyrronium, alone or in triple combination. The interaction was assessed by using Bliss Independence and Unified Theory theorems. KEY RESULTS: Beclomethasone/formoterol/glycopyrronium combination synergistically relaxed medium bronchi and small airways. Beclomethasone/formoterol/glycopyrronium combination at 100:6:12.5 combination ratio was a balanced drug mixture leading to very strong synergistic effect on relaxation of medium bronchi (Combination Index: from 0.042 to 0.96) and middle to very strong synergy in small airways (Combination Index: from 0.018 to 0.310). The synergy was related with the activation of intracellular glucocorticoid receptors and Gsα subunit G-protein of ß2 -adrenoceptors, leading to the modulation of cyclic AMP-dependent PKA pathway. CONCLUSION: Triple beclomethasone/formoterol/glycopyrronium combination induces synergistic bronchorelaxant effect in medium and small human airways, at least in ex vivo experiments. Further research is needed to confirm these findings in clinical studies in patients with asthma or COPD.

Single inhaler triple therapy with extrafine beclomethasone, formoterol, and glycopyrronium for the treatment of chronic obstructive pulmonary disease.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) management focuses on the alleviation of symptoms and prevention of exacerbations. Inhaled long acting bronchodilators and inhaled corticosteroids (ICS) are the main classes of treatment for COPD. Triple therapy with a long acting beta2-agonist (LABA), long acting muscarinic antagonist (LAMA), and ICS is commonly prescribed for symptomatic COPD patients experiencing regular exacerbations. Triple therapy is usually administered using separate inhalers; there is little clinical trial evidence of an effect on exacerbation prevention with this approach. Areas covered: This evaluation reviews the single inhaler extrafine combination containing beclometasone diproprionate (BDP), formoterol fumarate (FF), and glycopyrronium bromide (GB) which has been developed as a simplified triple regime. BDP/FF/GB significantly reduced exacerbation rates in three clinical trials (1-year duration) compared against LAMA monotherapy (20% exacerbation reduction), ICS/LABA combination (23% exacerbation reduction), and LAMA/LABA combination (15% exacerbation reduction). Expert opinion: The practical benefits of single inhaler triple therapy in the real world have not been studied. However, the robust clinical trial evidence that BDP/FF/GB reduces exacerbations compared to double combination treatments and LAMA monotherapy cements triple therapy positioning as an escalation step in COPD management pathways.

Efficacy and Safety of Beclomethasone Dipropionate versus 5-Aminosalicylic Acid in the Treatment of Ulcerative Colitis: A Systematic Review and Meta-Analysis.

BACKGROUND: Ulcerative colitis (UC) is a chronic and remitting inflammatory disease that is characterized by chronic idiopathic inflammation of the colon and bloody diarrhea. Currently drug treatment is the main intervention for patients with mild to moderate UC. Mesalazine (5-ASA) and beclomethasone dipropionate (BDP) have been widely used for the treatment of UC and have yielded satisfactory results. This study compared the effectiveness of 5-ASA and BDP in the treatment of UC. METHODS: The PubMed, Medline, SinoMed, Embase, and Cochrane Librinary databases were searched for eligible studies. Data were extracted by two of the coauthors independently and were analyzed using RevMan statistical software, version 5.3. Weighted mean differences (WMDs), odds ratios (ORs), and 95% confidence intervals (CIs) were calculated. Cochrane Collaboration's Risk of Bias Tool was used to assess the risk of bias. RESULTS: Seven randomized controlled trials that compared BDP with 5-ASA in treating UC were identified as eligible. The methodological quality of the trials ranged from low to moderate. A pooled analysis of effectiveness based on the Disease Activity Index (DAI) or other assessment method after treatment revealed that in the treatment of UC, there are no obvious differences between BDP and 5-ASA in inducing remission and clinical improvement (OR = 0.76, 95% CI = 0.56-1.03, P = 0.08). The total numbers of adverse events associated with BDP and 5-ASA treatments for UC were similar (OR = 1.21, 95% CI = 0.71-2.09, P = 0.48). The safety profiles for these two drugs are good. According to subgroup-analysis, we found no obvious differences of clinical efficacy between BDP and 5-ASA no matter oral or enema administration was used in the treatment of UC. A sensitivity analysis demonstrated the stability of the pooled results. CONCLUSION: During induction treatment of mild to moderate UC, there is no obvious difference between the two groups with respect to remission and clinical improvement. Given that the upper confidence limit for the OR barely exceeds 1.0 and that the p-value is close to 0.05 for this primary efficacy outcome as well as that the horizontal block lies to the left of the vertical line, it indicates that the clinical efficacy of BDP may be better than 5-ASA. However, taking into account that BDP has the risk of hypothalamic-pituitary-adrenal axis (HPA) suppression, 5-ASA has a potential advantage of safety in the treatment of mild to moderate UC.

Effect of tranilast in comparison with beclomethasone in chronic murine model of asthma.

AIM OF THE STUDY: The current investigation was taken to scrutinize the action of tranilast on the airway remodeling in chronic asthma in mice. MATERIALS AND METHODS: Intraperitoneal injection of ovalbumin was applied to mice for sensitization and subsequent inhalation of 1% ovalbumin three times week for 10 weeks for challenge. Beclomethasone or tranilast were given daily for the 10 week challenge period. At the end of the study, lung weight index, total collagen content, bronchoalveolar lavage level of total and differential cell counts, interleukin-13, in addition to lung tissue nitrate/nitrite and transforming growth beta-1 were measured. Also, histological analysis was done. RESULTS: Asthmatic mice demonstrated apparent fibrotic changes. Significant airway fibrosis was demonstrated by hyperplasia of goblet cells and thickening of airway epithelium, increased content of lung collagen, lung and bronchoalveolar lavage of transforming growth factor beta-1 and interleukin-13 mutually accompanied by reduction in nitrate/nitrite generation. CONCLUSIONS: Beclomethasone influence on airway remodeling was mediated mainly via suppression of eosinophilic recruitment into the airways and reduction of interleukin-13 cytokine levels. Whereas, tranilast effects on airway remodeling was found to be mainly mediated via its inhibitory effect on transforming growth beta-1. Both beclomethasone and tranilast influence airway remodeling by different degrees and mechanisms.

An update regarding the treatment of nonallergic rhinitis.

PURPOSE OF REVIEW: The review presents some information on known options for treatment of nonallergic rhinitis (NAR) with introduction to new therapies. The merits and limitations of recent advancements in pharmacotherapy of this common problem are briefly discussed as well. RECENT FINDINGS: Intranasal corticosteroids are first-line therapy for NAR. Fluticasone propionate and beclomethasone remain the only topical corticosteroids approved for NAR. The use of azelastine - another first-line option - has also been found to be effective even though NAR is a nonallergic entity by definition. Combination of fluticasone propionate and azelastine is a promising option in achieving better symptom reduction. Coadministration of intranasal corticosteroid and topical decongestants is an attractive topic that requires additional safety studies before recommending treatment. Although promising, no scientifically valid recommendation can be made for treatment of NAR with capsaicin. Surgical options in patients with refractory NAR are limited. New studies demonstrate a lack of correlation between objective outcome of radiofrequency ablation of the inferior turbinate and subjective patient symptoms. SUMMARY: The heterogeneity in clinical presentation makes NAR treatment a daily challenge for otolaryngologists. The diversity of clinical studies with use of unique outcome measures limit systematic reviews which may be instrumental in providing strong recommendations.

Beclomethasone dipropionate hydrofluoroalkane for the treatment of allergic rhinitis.

Allergic rhinitis (AR) is a common respiratory disease, and its prevalence is increasing all over the world, both in adults and in children. Patients experience symptoms that may negatively impact on physical, social and psychological well-being. Hence, if left untreated, allergic rhinitis may significantly affect quality of life. Under current guidelines, intranasal corticosteroids are considered the most effective drugs and they are recommended as first-line therapy. Among the several corticosteroid intranasal sprays available, beclomethasone dipropionate is one of the most prescribed. Recently, new intranasal hydrofluoroalkane-propelled formulations with little or no impact on the ozone layer have been developed for the treatment of AR. The use of these devices might improve patients' adherence to treatment, avoiding some of the most common side effects associated with aqueous formulations. This review provides the most recent evidence for the efficacy and safety of beclomethasone dipropionate hydrofluoroalkane nasal aerosol in the treatment of allergic rhinitis.

Enfermedad de Crohn y síndrome de Sweet: una asociación infrecuente / No disponible

El síndrome de Sweet o dermatosis neutrofílica febril aguda(SS) se caracteriza por la aparición brusca de lesiones eritematosas,(pápulas, nódulos y placas) dolorosas, junto con fiebre y neutrofilia,siendo de presentación poco frecuente. Las lesiones se localizanpreferentemente en manos, brazos, parte superior deltronco, cuello y cara, con distribución asimétrica. Suele haber elevaciónde reactantes de fase aguda y en las biopsias cutáneas seidentifica una infiltración dérmica de neutrófilos sin vasculitis. Seconsidera un marcador de enfermedad sistémica en más de la mitadde los casos, asociándose a infecciones, enfermedad inflamatoriaintestinal, conectivopatías autoinmunes y diversas neoplasias.Su asociación con la enfermedad de Crohn (EC) es poco habitual,asociado sobre todo a afectación colónica. Se han publicadomenos de 50 casos en la literatura médica desde su primera descripciónen 1964, algunos de ellos simultáneos con el primer brotede la EC. Presentamos dos pacientes con enfermedad deCrohn y síndrome de Sweet diagnosticados en nuestro servicio enel momento del diagnóstico de la EC, así como su respuesta al tratamiento,evolución posterior y revisión de la literatura científica(AU)

The uncommon Sweet’s syndrome or acute febrile neutrophilicdermatosis (SS) is characterized by the sudden onset of painfulerythematous lesions (papules, nodules, and plaques) togetherwith fever and neutrophilia. The lesions are typically located onhands, arms, upper trunk, neck and face, showing an asymmetricdistribution. Acute phase reactants are usually elevated and dermalinfiltration of neutrophils without vasculitis is seen on skinbiopsies. It is considered as a marker of systemic disease in overhalf of the cases, and is associated with infections, inflammatorybowel disease, autoimmune connective tissue disorders and variousneoplasias.Its association with Crohn’s disease (CD) is unusual and it appearsmainly in association with colonic involvement. Fewer than50 cases have been published in the medical literature since itsfirst description in 1964, some concurrent with the first episodeof CD. We present two patients with Crohn’s disease and Sweet’ssyndrome diagnosed in our department at the time of CD diagnosis,as well as their response to treatment, subsequent course ofthe disease, and a review of the scientific literature(AU)

Seasonal allergic rhinitis: limited effectiveness of treatments.

(1) Seasonal allergic rhinitis, otherwise known as hayfever, is a harmless condition, although it can cause major discomfort and interfere with activities of daily living. We conducted a review of the literature, based on our in-house methodology, to determine the risk-benefits of treatments used in this setting. (2) Placebo-controlled trials show that sodium cromoglicate relieves symptoms, especially if it is used before symptoms appear. Adverse effects are rare with sodium cromoglicate nasal solutions and eye drops. (3) Nasal steroids have well-documented efficacy. Beclometasone is the best choice. Adverse effects include epistaxis, nasal irritation and, occasionally, systemic disorders. (4) Oral antihistamines are less effective than nasal steroids. They also provoke adverse effects, especially drowsiness. Nasal azelastine seems to have a similar efficacy as oral antihistamines. (5) The adverse effects of systemic steroids must not be overlooked, especially with long-term use. Oral administration is an alternative for severe symptoms that do not respond to other treatments, although this is rarely the case. Long-acting intramuscular steroids carry an increased risk of adverse effects. (6) Despite evaluation in several randomised controlled trials, there is no firm evidence that homeopathic preparations have any specific efficacy in allergic rhinitis. (7) Vasoconstrictors, ipratropium and montelukast, have negative risk-benefit balances in hay fever. (8) When a single allergen is responsible (grasses, ragweed, birch), clinical trials suggest that specific desensitisation can provide a modest improvement. However, this treatment carries a risk of local adverse effects, as well as a risk of rare but severe anaphylactic reactions, especially in patients who also have unstable severe asthma. (9) Sublingual desensitisation seems to be even less effective than subcutaneous desensitisation in adults. Follow-up is too short to know whether there is a risk of severe anaphylactic reactions. The results of paediatric studies are even less convincing. (10) In practice, when drug therapy is needed to relieve symptoms of seasonal allergic rhinitis, sodium cromoglicate is the first-line treatment. If a nasal steroid solution is chosen, it should be used for the shortest possible period.

[Effects of long term use of beclomethasone dipropionate nasal spray on bone density with perennial allergic rhinitis].

OBJECTIVE: To study the effects of long term use of beclomethasone dipropionate (BDP) nasal spray on bone density with perennial allergic rhinitis (AR) in adults. METHOD: A 5-year randomized study was conducted on the effects of BDP nasal spray on serum calcium, phosphorus, alkaline phosphatase, and bone density determined before and after the treatment in 36 adult patients with perennial AR. 20-45 years of age, were randomly divided into 3 groups. That is group A (nasal spray 1 - <3 year), group B (nasal spray BDP 3 - <5 year) and group C (nasal spray BDP > or =5 year). The data were analyzed by paired t test. RESULT: The perennial AR were followed up for more than > or =1 year, > or =3 year and > or =5 year to observe the influences of nasal spray BDP. There were no significant difference between the data examined before and after the treatment (P > 0.05). Bone development is not influenced by nasal spray BDP < or =400 microg/d within 5 years. CONCLUSION: Long term use of BDP nasal spray in adult patients does not lead to osteoporosis if the lowest effective steroid dose is given.

A randomised controlled trial of the Buteyko technique as an adjunct to conventional management of asthma.

OBJECTIVE: To assess the effectiveness of a non-pharmacological intervention in patients with asthma on conventional therapy including inhaled corticosteroid. DESIGN: A randomised controlled trial of the Buteyko technique in a group of adults with asthma. The control group was trained by a physiotherapist in breathing and relaxation techniques. SETTING: A single centre associated with a University-based asthma programme. MAIN OUTCOME MEASURE: Asthma control, defined by a composite score based on the Canadian asthma consensus report 6 months after completion of the intervention. RESULTS: Both groups showed substantial and similar improvement and a high proportion with asthma control 6 months after completion of the intervention. In the Buteyko group the proportion with asthma control increased from 40% to 79% and in the control group from 44% to 72%. In addition the Buteyko group had significantly reduced their inhaled corticosteroid therapy compared with the control group (p=0.02). None of the other differences between the groups at 6 months were significant. CONCLUSIONS: Six months after completion of the interventions, a large majority of subjects in each group displayed control of their asthma with the additional benefit of reduction in inhaled corticosteroid use in the Buteyko group. The Buteyko technique, an established and widely recognised intervention, or an intensive programme delivered by a chest physiotherapist appear to provide additional benefit for adult patients with asthma who are being treated with inhaled corticosteroid.

Swimming and persons with mild persistant asthma.

The aim of our study was to analyze the effect of recreational swimming on lung function and bronchial hyperresponsiveness (BHR) in patients with mild persistent asthma. This study included 65 patients with mild persistent asthma, who were divided into two groups: experimental group A (n = 45) and control group B (n = 20). Patients from both groups were treated with low doses of inhaled corticosteroids (ICS) and short-acting beta2 agonists salbutamol as needed. Our program for patients in group A was combined asthma education with swimming (twice a week on a 1-h basis for the following 6 months). At the end of the study, in Group A, we found a statistically significant increase of lung function parameters FEV1 (forced expiratory volume in 1 sec) (3.55 vs. 3.65) (p < 0.01), FVC (forced vital capacity) (4.27 vs. 4.37) (p < 0.05), PEF (peak expiratory flow) (7.08 vs. 7.46) (p < 0.01), and statistically significant decrease of BHR (PD20 0.58 vs. 2.01) (p < 0.001). In Group B, there was a statistically significant improvement of FEV1 3.29 vs. 3.33 (p < 0.05) and although FVC, FEV1/FVC, and PEF were improved, it was not significant. When Groups A and B were compared at the end of the study, there was a statistically significant difference of FVC (4.01 vs. 4.37), FEV1 (3.33 vs. 3.55), PEF (6.79 vs.7.46), and variability (p < 0.001), and statistically significantly decreased BHR in Group A (2.01 vs. 1.75) (p < 0.001). Engagement of patients with mild persistent asthma in recreational swimming in nonchlorinated pools, combined with regular medical treatment and education, leads to better improvement of their parameters of lung function and also to more significant decrease of their airway hyperresponsiveness compared to patients treated with traditional medicine.

Meta-analysis: the efficacy of rectal beclomethasone dipropionate vs. 5-aminosalicylic acid in mild to moderate distal ulcerative colitis.

BACKGROUND: Beclomethasone dipropionate (BDP) is a second-generation steroid with topical effects and minimal systemic activity for patients with ulcerative colitis (UC). AIM: To review all available literature to assess the efficacy of enema/foam BDP compared with enema/foam 5-aminosalicylic acid (5-ASA) in the control of left-sided mild-moderate UC. METHODS: We selected randomized controlled trials of enema/foam BDP compared with enema/foam 5-ASA treatment in patients with UC. Two reviewers assessed trial quality and extracted data independently. RESULTS: Four trials involving 428 UC patients, 209 treated with 5-ASA (1-4 g o.d.) and 219 with BDP (3 mg o.d.), were included. Intention-to-treat analysis showed that 5-ASA induced improvement/remission of UC in 146 (69.9%) patients, while BDP in 143 (65.3%). The test for heterogeneity (Cochran Q) was not significant and Mantel-Haenszel pooled estimate of odds ratio was 1.23 (95% CI = 0.82-1.85). The results did not change when analysis was performed on a per-protocol basis. CONCLUSION: The randomized controlled trials identified in this review showed that rectal BDP has equal effect as 5-ASA to control symptoms in UC.

Beclomethasone dipropionate versus mesalazine in distal ulcerative colitis: a multicenter, randomized, double-blind study.

BACKGROUND: Topical beclomethasone diproprionate has shown efficacy in ulcerative colitis. AIM: To assess, in a multicenter, randomized, double-blind study, the tolerability and safety of topical beclomethasone diproprionate (3mg) enema and foam versus mesalazine (2g) enema and foam in mild-moderate distal ulcerative colitis. PATIENTS: In 15 referral gastrointestinal units, 99 patients with distal ulcerative colitis were enrolled. This number was lower than planned according to the statistical analysis, due to a low recruitment rate. METHODS: Patients were randomly assigned to random preparations (beclomethasone diproprionate enema, beclomethasone diproprionate foam, mesalazine enema, mesalazine foam) once nightly for 8 weeks, with clinical and endoscopical assessment (Disease Activity Index score) at baseline (T0), 4 (T4) and 8 weeks (T8). Results were expressed as median and range (95% confidence interval). The efficacy was assessed by comparing the Disease Activity Index value at T4 and T8 by using the Student's t-test or the Wilcoxon-Mann-Whitney test. RESULTS: Efficacy was comparable in the beclomethasone diproprionate or mesalazine groups at both T4 and T8 (response at T4: beclomethasone diproprionate 78% [95% confidence interval 0.6-0.8] versus mesalazine 79% [95% confidence interval 0.6-0.8]; T8: beclomethasone diproprionate 84% [95% confidence interval 0.7-0.9] versus mesalazine 90% [95% confidence interval 0.7-1.0]; p=n.s.; remission at T4: beclomethasone diproprionate 24% [95% confidence interval 0.1-0.3] versus mesalazine 28% [95% confidence interval 0.1-0.3]; remission at T8: beclomethasone diproprionate 36% [95% confidence interval 0.2-0.5] versus mesalazine 52% [95% confidence interval 0.3-0.6]; p=n.s.). The Disease Activity Index lowered at T4 and T8 versus T0 in the four groups (T4 versus T0: beclomethasone diproprionate foam Disease Activity Index 2 versus 6 p<0.0001; beclomethasone diproprionate enema 4 versus 6, mesalazine enema 3 versus 6, mesalazine foam 3.5 versus 7, p<0.001 for all three groups; T8 versus T0: p<0.01). The Disease Activity Index lowered at T8 versus T4 in the beclomethasone diproprionate enema and foam (Disease Activity Index: 2 versus 4 and 1 versus 4, respectively; p<0.05) and in the mesalazine enema (Disease Activity Index: 1.5, range 0-4 versus 3, range 0-12; p<0.01), but not in the mesalazine foam group (Disease Activity Index: 1, range 0-9 versus 3.5, range 0-8; p=n.s.). The safety profile was favourable for all groups. CONCLUSIONS: Beclomethasone diproprionate and mesalazine enema and foam show a comparable tolerability and efficacy in mild active distal ulcerative colitis.

Asthma control during the year after bronchial thermoplasty.

BACKGROUND: Bronchial thermoplasty is a bronchoscopic procedure to reduce the mass of airway smooth muscle and attenuate bronchoconstriction. We examined the effect of bronchial thermoplasty on the control of moderate or severe persistent asthma. METHODS: We randomly assigned 112 subjects who had been treated with inhaled corticosteroids and long-acting beta2-adrenergic agonists (LABA) and in whom asthma control was impaired when the LABA were withdrawn to either bronchial thermoplasty or a control group. The primary outcome was the frequency of mild exacerbations, calculated during three scheduled 2-week periods of abstinence from LABA at 3, 6, and 12 months. Airflow, airway responsiveness, asthma symptoms, the number of symptom-free days, use of rescue medication, and scores on the Asthma Quality of Life Questionnaire (AQLQ) and the Asthma Control Questionnaire (ACQ) were also assessed. RESULTS: The mean rate of mild exacerbations, as compared with baseline, was reduced in the bronchial-thermoplasty group but was unchanged in the control group (change in frequency per subject per week, -0.16+/-0.37 vs. 0.04+/-0.29; P=0.005). At 12 months, there were significantly greater improvements in the bronchial-thermoplasty group than in the control group in the morning peak expiratory flow (39.3+/-48.7 vs. 8.5+/-44.2 liters per minute), scores on the AQLQ (1.3+/-1.0 vs. 0.6+/-1.1) and ACQ (reduction, 1.2+/-1.0 vs. 0.5+/-1.0), the percentage of symptom-free days (40.6+/-39.7 vs. 17.0+/-37.9), and symptom scores (reduction, 1.9+/-2.1 vs. 0.7+/-2.5) while fewer puffs of rescue medication were required. Values for airway responsiveness and forced expiratory volume in 1 second did not differ significantly between the two groups. Adverse events immediately after treatment were more common in the bronchial-thermoplasty group than in the control group but were similar during the period from 6 weeks to 12 months after treatment. CONCLUSIONS: Bronchial thermoplasty in subjects with moderate or severe asthma results in an improvement in asthma control. (ClinicalTrials.gov number, NCT00214526 [ClinicalTrials.gov].).

Psoriasis en gotas / Guttate psoriasis

La psoriasis es una enfermedad cutánea, eritemato descamativa, de carácter inflamatorio, de curso crónico y recidivante y etiología desconocida. El diagnóstico es fundamentalmente clínico, aunque en ocasiones hay que recurrir a la biopsia, y se caracteriza por lesiones consistentes en pápulas y placas eritemato descamativas bien definidas, muchas veces pruriginosas. Presentamos el caso de una paciente de 20 años con un cuadro de psoriasis en gotas (AU)

Psoriasis is an inflammatory skin disease causing scaly, erythematous patches to appear on the skin. It is a chronic, reoccurring condition of unknown aetiology. The diagnosis is mainly clinical although on occasions a skin biopsy may be needed. It is characterized by red, scaly papules or plaques with well-defined borders which are often itchy. In this report we present a case of guttate psoriasis in a 20 year old female patient (AU)
