RESUMO

BACKGROUND: We report the results of a phase IIB study investigating the safety and effectiveness of atorvastatin use with standard anti-TB drugs.METHODS: In this multicentre, open-labelled study, we recruited treatment-naÏve patients with uncomplicated pulmonary TB aged at least 18 years. Participants were randomly assigned to standard-of-care or standard-of-care plus oral dose of atorvastatin (40 mg) daily for 2 months. Primary end points were safety measured by the number of participants with severe adverse events and effectiveness measured by the number of participants with negative sputum culture. Secondary endpoint was chest X-ray (CXR) severity score.RESULTS: Of the 185 participants screened, 150 were enrolled and equally assigned to the standard-of-care and atorvastatin groups. Adverse event severity was similar in the two groups. There was increased frequency of muscle pain in the trial group (12/75, 16% vs. 4/75, 5%). For efficacy analysis, respectively 64 (97%) and 57 (85.1%) patients in the trial and control groups had culture-negative results (P = 0.02) and experienced a reduction in CXR severity score of respectively 37% and 22%, with a mean difference of 1.4-4.9%.CONCLUSION: Atorvastatin is safe and associated with improved microbiological and radiological outcomes in TB.

RESUMO

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disorder that affects millions of people worldwide and inhalation therapy is central to the symptomatic management of the disease. Therefore, knowledge of the minimum Peak inspiratory flow (PIF) requirements for specific inhalers especially dry powder inhalers (DPI's) is necessary when prescribing inhalation therapy. The purpose of this study is to assess the effect of COPD severity on PIF in patients with COPD. METHODOLOGY: A total of 150 subjects (75 patients with stable COPD, and 75 apparently healthy subjects) participated in the study. PIF was assessed using the In-check Inhaler Assessment Kit (manufactured by Clement Clarke International Ltd, Harlow, UK). Lung function was assessed by spirometry with subjects divided into four groups based on the severity of their airway obstruction using the GOLD criteria. The Modified Medical Research Council (MMRC) dyspnea scale was used to assess dyspnea severity. Exercise capacity was assessed using the 6-minute walk test. Statistical analysis was performed with SPSS 23.0 software. In all the statistical tests, a p value of <0.05 was considered significant. RESULTS: The mean age for the COPD patient and control population are 72.48 ± 8.01 and 70.69 ± 5.82 respectively. The control group had higher PIF than COPD group; however, only the clickhler and pMDI had statistically significant difference between the mean PIF of the patients compared with the control group. Generally, there was an observed trend of a decrease in mean PIF as the COPD stage progresses with a statistically significant difference observed for Easibreathe (F= 3.52, p= 0.019) and pressurized Metered dose inhaler (pMDI) (F= 4.26, p= 0.008). There was a significant positive correlation between FEV1%, FVC, Exercise capacity (6-minute walk distance) and PIF for Clickhaler, Autohaler, Easybreathe and pMDI. For pMDI, there was a statistically significant difference between means of PIF across the MMRC dyspnea scale with PIF decreasing with increasing severity of dyspnea (F= 2.85, p= 0.033). CONCLUSION: COPD patients have slightly lower PIF than controls. Poor exercise tolerance and lower spirometric pulmonary function parameters may contribute to low PIF.


INTRODUCTION: La bronchopneumopathie chronique obstructive (BPCO) est un trouble respiratoire chronique qui touche des millions de personnes dans le monde et la thérapie par inhalation est essentielle à la gestion symptomatique de la maladie. Par conséquent, il est nécessaire de connaître les exigences minimales en matière de débit inspiratoire de pointe (DIP) pour certains inhalateurs, en particulier les inhalateurs de poudre sèche (IPS), lors de la prescription d'un traitement par inhalation. L'objectif de cette étude est d'évaluer l'effet de la gravité de la BPCO sur le débit de pointe inspiratoire chez les patients atteints de BPCO. MÉTHODOLOGIES: Un total de 150 sujets (75 patients atteints de BPCO stable et 75 sujets apparemment sains) ont participé à l'étude. Le PIF a été évalué à l'aide du kit d'évaluation In-check Inhaler (fabriqué par Clement Clarke International Ltd, Harlow, UK). La fonction pulmonaire a été évaluée par spirométrie, les sujets étant répartis en quatre groupes en fonction de la gravité de l'obstruction des voies respiratoires selon les critères GOLD. L'échelle de dyspnée modifiée du Medical Research Council (MMRC) a été utilisée pour évaluer la sévérité de la dyspnée. La capacité d'exercice a été évaluée à l'aide du test de marche de 6 minutes. L'analyse statistique a été réalisée avec le logiciel SPSS 23.0. Dans tous les tests statistiques, une valeur p de <0,05 a été considérée comme significative. RÉSULTATS: L'âge moyen des patients atteints de BPCO et de la population de contrôle est respectivement de 72,48 ± 8,01 et 70,69 ± 5,82. Le groupe de contrôle avait un PIF plus élevé que le groupe BPCO; cependant, seuls le clickhler et le pMDI présentaient une différence statistiquement significative entre le PIF moyen des patients et celui du groupe de contrôle. D'une manière générale, on a observé une tendance à la diminution du FRP moyen au fur et à mesure de l'évolution de la BPCO, avec une différence statistiquement significative pour l'Easibreathe (F= 3,52, p= 0,019) et l'aérosol-doseur pressurisé (pMDI) (F= 4,26, p= 0,008). Il existe une corrélation positive significative entre le VEMS, la CVF, la capacité d'exercice (distance de marche de 6 minutes) et le PIF pour Clickhaler, Autohaler, Easybreathe et pMDI. Pour le pMDI, il y avait une différence statistiquement significative entre les moyennes de PIF sur l'échelle de dyspnée du MMRC, le PIF diminuant avec l'augmentation de la sévérité de la dyspnée (F= 2,85, p= 0,033). CONCLUSION: Les patients atteints de BPCO ont un PIF légèrement inférieur à celui des témoins. Une mauvaise tolérance à l'exercice et des paramètres spirométriques de la fonction pulmonaire plus faibles peuvent contribuer à la faiblesse du PIF.

RESUMO

BACKGROUND: The aim of these clinical standards is to aid the diagnosis and management of asthma in low-resource settings in low- and middle-income countries (LMICs).METHODS: A panel of 52 experts in the field of asthma in LMICs participated in a two-stage Delphi process to establish and reach a consensus on the clinical standards.RESULTS: Eighteen clinical standards were defined: Standard 1, Every individual with symptoms and signs compatible with asthma should undergo a clinical assessment; Standard 2, In individuals (>6 years) with a clinical assessment supportive of a diagnosis of asthma, a hand-held spirometry measurement should be used to confirm variable expiratory airflow limitation by demonstrating an acute response to a bronchodilator; Standard 3, Pre- and post-bronchodilator spirometry should be performed in individuals (>6 years) to support diagnosis before treatment is commenced if there is diagnostic uncertainty; Standard 4, Individuals with an acute exacerbation of asthma and clinical signs of hypoxaemia or increased work of breathing should be given supplementary oxygen to maintain saturation at 94-98%; Standard 5, Inhaled short-acting beta-2 agonists (SABAs) should be used as an emergency reliever in individuals with asthma via an appropriate spacer device for metered-dose inhalers; Standard 6, Short-course oral corticosteroids should be administered in appropriate doses to individuals having moderate to severe acute asthma exacerbations (minimum 3-5 days); Standard 7, Individuals having a severe asthma exacerbation should receive emergency care, including oxygen therapy, systemic corticosteroids, inhaled bronchodilators (e.g., salbutamol with or without ipratropium bromide) and a single dose of intravenous magnesium sulphate should be considered; Standard 8, All individuals with asthma should receive education about asthma and a personalised action plan; Standard 9, Inhaled medications (excluding dry-powder devices) should be administered via an appropriate spacer device in both adults and children. Children aged 0-3 years will require the spacer to be coupled to a face mask; Standard 10, Children aged <5 years with asthma should receive a SABA as-needed at step 1 and an inhaled corticosteroid (ICS) to cover periods of wheezing due to respiratory viral infections, and SABA as-needed and daily ICS from step 2 upwards; Standard 11, Children aged 6-11 years with asthma should receive an ICS taken whenever an inhaled SABA is used; Standard 12, All adolescents aged 12-18 years and adults with asthma should receive a combination inhaler (ICS and rapid onset of action long-acting beta-agonist [LABA] such as budesonide-formoterol), where available, to be used either as-needed (for mild asthma) or as both maintenance and reliever therapy, for moderate to severe asthma; Standard 13, Inhaled SABA alone for the management of patients aged >12 years is not recommended as it is associated with increased risk of morbidity and mortality. It should only be used where there is no access to ICS.The following standards (14-18) are for settings where there is no access to inhaled medicines. Standard 14, Patients without access to corticosteroids should be provided with a single short course of emergency oral prednisolone; Standard 15, Oral SABA for symptomatic relief should be used only if no inhaled SABA is available. Adjust to the individual's lowest beneficial dose to minimise adverse effects; Standard 16, Oral leukotriene receptor antagonists (LTRA) can be used as a preventive medication and is preferable to the use of long-term oral systemic corticosteroids; Standard 17, In exceptional circumstances, when there is a high risk of mortality from exacerbations, low-dose oral prednisolone daily or on alternate days may be considered on a case-by-case basis; Standard 18. Oral theophylline should be restricted for use in situations where it is the only bronchodilator treatment option available.CONCLUSION: These first consensus-based clinical standards for asthma management in LMICs are intended to help clinicians provide the most effective care for people in resource-limited settings.

RESUMO

BACKGROUND: Shoulder pain syndrome (SPS) is a chronic condition affecting the shoulder joint, its periarticular structures, or less commonly, radicular pain typically from the neck. OBJECTIVES: The objectives of this study were to assess the frequency and pattern of shoulder pain syndrome in OAUTHC, Ile-Ife. METHODOLOGY: This was a descriptive study in which 50 patients with shoulder pain were recruited from the medical and general outpatient departments of Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC), Ile-Ife over six months out of 350 patients with various musculoskeletal complaints. Detailed history, physical examinations and laboratory tests were done. Plain radiographs were taken for all the patients. Ethical approval was obtained and data analyzed using SPSS version 20.0. RESULTS: The frequency of shoulder pain was 14.3%. Eighteen were males and 32 were females with a M: F ratio of 1:1.7. The mean age for all the patients was 59.74years (±10.64) with patients in the age range 50-59years accounting for the highest proportion (38%). The most common cause of shoulder pain syndrome was rotator cuff tendinopathy accounting for 72% of cases. Diabetes was the most frequent comorbidity and was found in 50% of patients. CONCLUSION: Shoulder pain predominantly occurs in females with people in the fifth decade mostly affected. The most frequent cause of shoulder pain syndrome in this environment is rotator cuff disorder. Diabetes mellitus is an important comorbidity associated with shoulder pain. Therefore, management of shoulder pain should include assessment for risk factors.


CONTEXTE: Le syndrome douloureux de l'épaule (SPS) est une affection chronique qui touche l'articulation de l'épaule, ses structures périarticulaires ou, plus rarement, une douleur radiculaire provenant généralement du cou. OBJECTIFS: Les objectifs de cette étude étaient d'évaluer la fréquence et les caractéristiques du syndrome douloureux de l'épaule à l'OAUTHC, Ile-Ife. MÉTHODOLOGIES: il s'agit d'une étude descriptive dans laquelle 50 patients souffrant de douleurs à l'épaule ont été recrutés dans les services de consultation médicale et générale du complexe hospitalier universitaire Obafemi Awolowo (OAUTHC), à Ile-Ife, sur une période de six mois, parmi 350 patients souffrant de diverses affections musculo-squelettiques. Des antécédents détaillés, des examens physiques et des tests de laboratoire ont été effectués. Des radiographies simples ont été prises pour tous les patients. L'approbation éthique a été obtenue et les données ont été analysées à l'aide de la version 20.0 de SPSS. RÉSULTATS: La fréquence de la douleur à l'épaule était de 14,3 %. Dix-huit patients étaient des hommes et 32 des femmes, soit un rapport M/F de 1/1,7. L'âge moyen de tous les patients était de 59,74 ans (±10.64), les patients âgés de 50 à 59 ans représentant la proportion la plus élevée (38 %). La cause la plus fréquente du syndrome douloureux de l'épaule était la tendinopathie de la coiffe des rotateurs, qui représentait 72 % des cas. Le diabète est la comorbidité la plus fréquente et concerne 50 % des patients. CONCLUSION: Les douleurs à l'épaule touchent principalement les femmes et les personnes de la cinquième décennie sont les plus touchées. La cause la plus fréquente du syndrome douloureux de l'épaule dans cet environnement est le trouble de la coiffe des rotateurs. Le diabète sucré est une comorbidité importante associée à la douleur à l'épaule. Par conséquent, la prise en charge de la douleur à l'épaule devrait inclure l'évaluation des facteurs de risque.

RESUMO

BACKGROUND: Inhalational therapy is the cornerstone in the management of chronic obstructive pulmonary disease (COPD) patients. Patients' peak inspiratory flow impacts effective dry powder inhaler (DPI) delivery and management outcome. OBJECTIVE: This study assessed peak inspiratory flow rates (PIFR) and determined the factors associated with suboptimal inspiratory flow rates among COPD patients. METHODS: A descriptive cross-sectional study was conducted among 60 participants (30 stable COPD patients and 30 age-and-sex matched controls). Socio-demographic characteristics was obtained and spirometry was done for all participants. PIFR assessment was done using the In-Check Dial Meter and was categorized as suboptimal (< 60L/min) or optimal (≥ 60L/min). P values less than 0.05 were taken as statistically significant. RESULTS: Mean age of the COPD patients and healthy controls were both 67.8 ± 10.3 years, with 53.3% being females. Post-bronchodilation FEV 1/FVC% for COPD patients was 54.15 ± 11.27%. The mean PIFR among COPD patients was significantly lower than that of healthy controls, in all DPIs simulated, especially for Clickhaler (46.2±13.4 vs 60.5±11.4L/min, p<0.001). A significant proportion of COPD patients had suboptimal PIFR, in the simulated resistances against Clickhaler and Turbuhaler (70% vs 80%; p<0.001). Older age, shorter height and low BMI were associated with suboptimal PIFR among COPD patients. However, independent predictors of suboptimal PIFR were BMI, PEFR, FEV1% and FVC%. CONCLUSION: Suboptimal PIFR was found in a significant number of COPD patients when compared with healthy respondents. Routine assessment using In-Check Dial meter should be done to determine the suitability of dry powder inhalers for patients with COPD.


CONTEXTE: Le traitement par inhalation est la pierre angulaire de la prise en charge des patients atteints de bronchopneumopathie chronique obstructive (BPCO). Le débit inspiratoire de pointe des patients a une incidence sur l'efficacité de l'inhalateur de poudre sèche et sur les résultats de la prise en charge. OBJECTIF DE L'ÉTUDE: Cette étude a évalué les débits inspiratoires de pointe et déterminé les facteurs associés aux débits inspiratoires sousoptimaux chez les patients atteints de BPCO. MÉTHODES: Une étude transversale descriptive a été menée auprès de 60 participants (30 patients atteints de BPCO stable et 30 témoins appariés selon l'âge et le sexe). Les caractéristiques socio-démographiques ont été recueillies et une spirométrie a été effectuée pour tous les participants. L'évaluation du PIFR a été réalisée à l'aide du Dial Meter In-Check et a été catégorisée comme suboptimale (< 60L/min) ou optimale (≥ 60L/min). Les valeurs P inférieures à 0,05 ont été considérées comme statistiquement significatives. RÉSULTATS: L'âge moyen des patients atteints de BPCO et des témoins sains était de 67,8 ± 10,3 ans, avec 53,3 % de femmes. Le pourcentage de VEMS/FVC après bronchodilatation chez les patients atteints de BPCO était de 54,15 ± 11,27 %. Le PIFR moyen des patients atteints de BPCO était significativement plus faible que celui des témoins sains, pour tous les DPI simulés, en particulier pour le Clickhaler (46,2±13,4 vs 60,5±11,4L/min, p<0,001). Une proportion significative de patients atteints de BPCO avait un PIFR sous-optimal, dans les résistances simulées contre Clickhaler et Turbuhaler (70% vs 80% ; p<0.001). L'âge avancé, la petite taille et un faible IMC étaient associés à une PIFR sous-optimale chez les patients atteints de BPCO. Cependant, les prédicteurs indépendants du PIFR suboptimal étaient l'IMC, le DEP, le VEMS et la CVF. CONCLUSION: Un nombre significatif de patients atteints de BPCO présente un PIFR sous-optimal par rapport aux personnes interrogées en bonne santé. Une évaluation de routine à l'aide de l'appareil de mesure In-Check Dial devrait être effectuée pour déterminer si les inhalateurs de poudre sèche conviennent aux patients atteints de BPCO.
