Marc Miravitlles, Antonio Anzueto
Chronic infections are associated with exacerbation in patients with chronic obstructive pulmonary disease (COPD). The major objective of the management of these patients is the prevention and effective treatment of exacerbations. Patients that have increased sputum production, associated with purulence and worsening shortness of breath, are the ones that will benefit from antibiotic therapy. It is important to give the appropriate antibiotic therapy to prevent treatment failure, relapse, and the emergence of resistant pathogens...

There is increasing evidence supporting the use of corticotropin as an alternative treatment of refractory proteinuric glomerulopathies. The efficacy of short-acting corticotropin, however, remains unknown and was tested here in an adolescent with steroid-dependent nephrotic syndrome caused by minimal change disease. After developing Cushing syndrome and recently being afflicted with severe cellulitis, the patient was weaned off all immunosuppressants, including corticosteroids. This resulted in a relapse of generalized anasarca, associated with massive proteinuria and hypoalbuminemia...

BACKGROUND: Corticosteroids are the basis of treatment for nephrotic syndrome due to minimal change disease (MCD), but 25% of patients have frequently relapsing nephrotic syndrome (FRNS) and 30% become steroid dependent. Prolonged use of conventional immunosuppressants causes significant toxicity. Rituximab (RTX) is now included in guidelines for childhood MCD. Evidence for use in adult MCD is limited. We describe a single-centre experience of RTX use in adult MCD. METHODS: Outcomes of all adult MCD patients treated with RTX for FRNS between 2008 and 2015 were retrospectively analysed...

True renal lupus vasculitis (TRLV), a vascular lesion usually associated with proliferative lupus nephritis (LN), is resistant to conventional treatments. The expression of P-glycoprotein (P-gp) on activated lymphocytes causes drug resistance. We herein report a patient with TRLV, minimal change LN, overexpression of P-gp on peripheral B cells, and accumulation of P-gp(+) B cells at the site of TRLV. High-dose corticosteroids combined with intravenous cyclophosphamide pulse therapy resulted in clinical remission and the long-term normal renal function...

Nail involvement in pemphigus vulgaris (PV) is an unusual clinical finding. The most common clinical manifestations include chronic paronychia and onychomadesis. We report an adult female patient with PV who initially presented with chronic paronychia of multiple fingernails and toenails before the onset of vesiculobullous eruptions. Later on, after complete resolution, there was recurrence of pemphigus presenting as hemorrhagic paronychia of the left index finger. Systemic treatment with corticosteroids and azathioprine led to complete resolution of mucocutaneous lesions as well as nail manifestations...

Type 2 diabetes is increasingly recognized as a risk factor for Alzheimer's disease, but the underlying mechanisms remain poorly understood. Hyperphosphorylation of the microtubule-associated protein tau has been reported in rodent models of diabetes, including db/db mice, which exhibit insulin resistance and chronically elevated glucocorticoids due to leptin receptor insufficiency. In this report, we investigated endocrine mechanisms for hippocampal tau phosphorylation in db/db and wild-type mice. By separately manipulating peripheral and intrahippocampal corticosterone levels, we determined that hippocampal corticosteroid exposure promotes tau phosphorylation and activates glycogen synthase kinase 3β (GSK3β)...

BACKGROUND: The neutrophil to lymphocyte ratio (NLR) has been shown to be highly prognostic across many tumor types, and predictive of treatment outcome in advanced prostate cancer, and has been postulated to be an indirect measure of tumor inflammation. We evaluated the effect of low-dose steroids on NLR in men suffering from castration-resistant prostate cancer (CRPC). PATIENTS AND METHODS: The NLR was evaluated in a prospective randomized phase II trial that compared prednisolone 5 mg twice daily and dexamethasone 0...

Lipopolysaccharide (LPS) contributes to asthma exacerbations and development of inhaled corticosteroid insensitivity. Complete resistance to systemic corticosteroids is rare and most patients lie on a continuum of steroid responsiveness. The objective of this study was to examine the sensitivity of combined ovalbumin- (Ova) and LPS-induced functional and inflammatory responses to inhaled and systemic corticosteroid in conscious guinea-pigs, to test the hypothesis that the route of administration affects its sensitivity...

Some recent salient publications related to inhaled drug therapy are discussed. Unexpectedly, a 2.5-μg once-daily dose of tiotropium (Respimat) had greater efficacy than the 5.0-μg daily dose. Occurrence of a reverse dose response serves to caution us that administering more drug is not always beneficial. Small-airway inflammation contributes to pathogenesis of asthma, especially severe asthma. However, there is no conclusive evidence that the use of small-particle aerosols to target small airways improves clinical outcomes in controlled clinical trials...

BACKGROUND: Allergic bronchopulmonary aspergillosis (ABPA) affects 3-13% of patients with asthma. Its natural history includes possibly life-threatening exacerbations and evolution towards fixed obstructive ventilatory disorders or even irreversible lung fibrosis lesions. ABPA prognosis is directly associated with exacerbation control and the main objective of the treatment is to decrease their frequency and duration. Recommendations regarding dosage and duration of treatment are not very precise...

Focal segmental glomerulosclerosis (FSGS) is a frequent glomerular kidney disease that is revealed by proteinuria or even nephrotic syndrome. A diagnosis can be established from a kidney biopsy that shows focal and segmental glomerulosclerosis. This histopathological lesion may be caused by a primary podocyte injury (idiopathic FSGS) but is also associated with other pathologies (secondary FSGS). The first-line treatment for idiopathic FSGS with nephrotic syndrome is a prolonged course of corticosteroids. However, steroid resistance or steroid dependence is frequent, and despite intensified immunosuppressive treatment, FSGS can lead to end-stage renal failure...

Most children with asthma have their disease easily controlled if low-dose inhaled corticosteroids (ICSs) are regularly and correctly administered. If a child presents with asthma which is apparently resistant to therapy with high-dose ICS and other controllers, then they have problematic severe asthma. However, in light of the UK National Review of Asthma Deaths, definitions of severe asthma based solely on the levels of prescribed treatment are too narrow. A detailed assessment of all such children should be performed...

Both Th2 cells and group 2 innate lymphoid cells (ILC2s) contribute to allergic diseases. However, their exact role and relationship in nasal allergic disorders is unclear. In this study, we investigated the cooperation of Th2 cells and ILC2s in a mouse model of nasal allergic disorder. To differentially activate Th2 cells and/or ILC2s in nasal mucosa, mice were intranasally administered ovalbumin (OVA) antigen, papain, an ILC2-activator, or both for 2 weeks. Epithelial thickness and number of eosinophils in the nasal mucosa were evaluated at 24 hours after the final challenge...

BACKGROUND: Most cases of childhood nephrotic syndrome (NS) are due to minimal change disease (MCD), while a minority of children have focal segmental glomerulosclerosis (FSGS) and an unfavorable clinical course, requiring a kidney biopsy to confirm diagnosis. We hypothesized that clinical characteristics at diagnosis and initial response to corticosteroid treatment accurately predict FSGS and can be used to guide consistent practice in the indications for kidney biopsy. METHODS: This was a case control study (1990-2012)...

BACKGROUND: Chronic tendinopathy is a significant problem particularly in active populations limiting sporting and occupational performance. The prevalence of patellar tendinopathy in some sports is near 50% and the incidence of lower limb tendinopathy is 1.4% p.a. in the UK Military. Management includes isometric, eccentric, heavy slow resistance exercises and extracorporeal shockwave therapy (ESWT). Often these treatments are inadequate yet there is no good evidence for injection therapies and success rates from surgery can be as low as 50%...
