Impacto del ejercicio físico en pacientes con enfermedad renal crónica: revisión sistemática y metaanálisis

Physical exercise may offer multiple benefits to patients with chronic kidney disease (CKD). However, it was not traditionally recommended because of the possibility of impairing renal function and increasing proteinuria. The objective of this study is to review the clinical trials on physical exercise in patients with CKD and describe its effect on the progression of kidney disease and other factors associated. Randomized clinical trials (RCT) comparing an intervention that included an exercise component with a control group without physical exercise in non-dialysis patients with CKD from 2007 to 2018 in English and Spanish were included. PubMed, Scopus, Embase, Ovid (Medline) and PEDro databases were used for the search. Effects of physical exercise were summarized by the standardized mean difference (SMD). No differences were found in glomerular filtration rate or proteinuria between the intervention group and the control group: SMD −0.3 (P = .81); SMD 26.6 (P = .82). Positive effects were obtained on peak oxygen consumption: SMD 2.5 (P < .001), functional capacity: SMD 56.6 (P < .001), upper limb strength: SMD 6.8 (P < .001) and hemoglobin: SMD 0.3 (P = .003). An improvement on the quality of life was also evident using the KDQOL-36 survey: SMD 3.56 (P = .02) and the SF-36 survey: SMD 6.66 (P = .02). In conclusion, the practice of low-intensity physical exercise routinely has no negative impact on renal function. On the contrary, it improves aerobic and functional capacity, impacting positively on the quality of life.     

Cribado de enfermedad pulmonar intersticial difusa en pacientes con artritis reumatoide: una revisión sistemática

AimsInterstitial lung disease (ILD) is frequent in patients with rheumatoid arthritis (RA) and is associated with significant morbidity and mortality. The aim of this review was to identify the different screening methods for ILD in patients with RA.MethodsWe ran a systematic search in Pubmed, Embase and Cochrane Library up to April 2020 and did a hand search of the references of the retrieved articles. The search was limited to humans and articles published in English, Spanish or French. We selected studies with any design where: a) the population included adult patients with RA; b) the intervention was any screening method for ILD; and c) validity or reliability of the screening method were evaluated, or a screening method was described. Two reviewers independently screened the articles by title and abstract and subsequently extracted the information using a specific data extraction form.Results25 studies were included with a total of 2,593 patients. The most frequently used tool for ILD screening was high resolution computed tomography (HRCT) of the lung. Electronic auscultation, biochemical markers, bronchoalveolar lavage (BAL), pulmonary function tests (PFTs) and lung ultrasonography were also evaluated. Across the different studies, electronic auscultation and lung ultrasonography achieved higher accuracy than PFTs, BAL and biochemical markers.ConclusionsHRCT resulted as the most sensitive tool for ILD screening in patients with RA. Given its harmlessness and high sensitivity, lung ultrasonography may become the first-choice tool in the future.

Tratamiento ideal del Helicobacter pylori: una revisión sistemática

BackgroundThe success rates of therapies for treating Helicobacter pylori vary greatly worldwide and the ideal treatment has yet to be clearly established.AimsA systematic review was carried out to evaluate the effectiveness of current first and second-line therapies in treating H. pylori infection.MethodsTwo researchers independently carried out Internet search engine reviews (PUBMED, EMBASE, MEDLINE) of clinical trials on adults published between 1990 and 2012 in both English and Spanish.ResultsForty-three (n = 8,123) clinical trials were evaluated that included first and second-line triple, quadruple, and sequential therapies. The eradication rates of the standard triple therapy are unacceptable (≤ 80%) in countries where H. pylori is highly resistant to clarithromycin and metronidazole. Administration of the standard triple therapy for more than 7 days does not improve its effectiveness. No statistically significant differences were observed between the eradication rates of the quadruple therapy with bismuth and the standard triple therapy. Even though the sequential and concomitant therapies are equally successful regimens, the triple therapy with levofloxacin offers the best results as first and second-line treatment, but quinolone resistance can diminish its effectiveness. The triple therapy with levofloxacin and the sequential and concomitant treatments were superior to the standard triple regimen as first-line therapy.ConclusionsCurrently there is no ideal first or second-line treatment for achieving 100% eradication. The therapeutic order should be carried out according to the initial treatment and local antimicrobial resistance studies.

Enfermedad diverticular de colon no complicada sintomática: revisión sistemática del diagnóstico y tratamiento

Symptomatic uncomplicated diverticular colon disease (SUDCD) is a highly prevalent disease in our setting, which significantly affects the quality of life of patients. Recent changes in understanding the natural history of this disease and technological and pharmacological advances have increased the available options for both diagnosis and treatment. However, consensus regarding the use of these options is scarce and sometimes lacks scientific evidence. The objective of this systematic review is to clarify the existing scientific evidence and analyse the use of the different diagnostic and therapeutic options for SUDCD, comparing their advantages and disadvantages, to finally suggest a diagnostic-therapeutic algorithm for this pathology and, at the same time, propose new research questions.     

Rentabilidad diagnóstica y seguridad de la criobiopsia pleural durante la toracoscopia médica en el estudio del derrame pleural. Una revisión sistemática y metaanálisis

ObjectiveCurrent evidence on the diagnostic yield and safety of pleural cryobiopsy (CB) is based on a series of heterogeneous studies with limited cohorts. A pooled analysis of these studies could improve the evidence and contribute to a better understanding of this new technique.MethodologyWe performed a systematic review and meta-analysis of published studies that included data on the yield and diagnostic safety of pleural CB compared with procedures performed using conventional flexible forceps. The heterogeneity of the analysis was evaluated by determining the I² index, while study quality was measured with the QUADAS-2 tool.ResultsSeven studies involving 356 patients were used for the final evaluation. In 55.6%, the etiology of the pleural effusion was malignant, 61.1% of which were lung cancer. The diagnostic yield of pleural CB was 95% (95% CI 92-97) vs. 91% (95% CI 87-94) with conventional flexible forceps (P = .019). Mild bleeding was reported in 67% of CB procedures (95% CI 62-72) compared with 85% of conventional flexible forceps procedures (95% CI 79-90) (P < .001). CB specimens were larger, and fewer artifacts were detected. A pooled analysis of the detection of molecular changes could not be performed. Heterogeneity was moderate to high, although the quality of the studies was acceptable.ConclusionsPleural CB is a safe technique with a high yield for etiological diagnosis of pleural effusion, and larger specimens with fewer artifacts are obtained. Molecular determinations should be investigated in more depth.     

Caracterización y prevalencia de manifestaciones extraintestinales en una cohorte de pacientes con enfermedad inflamatoria intestinal en Medellín (Colombia)

IntroductionExtraintestinal manifestations (EIMs) are frequent in patients with inflammatory bowel disease (IBD). Our objective is to characterize and determine the prevalence of MEIs in our cohort of patients with IBD.Patients and methodsA retrospective study was carried out in adult patients with IBD at the Pablo Tobón Uribe Hospital in Medellín. Colombia. Articular MEIs, primary sclerosing cholangitis (PSC), both ophthalmological and dermatological, were considered. Absolute and relative frequencies were used. The Chi square test of independence was used to compare 2 proportions and the odds ratio (OR) was estimated.ResultsOur registry has 759 patients with IBD, 544 present UC (71.6%), 200 CD (26.3%) and 15 unclassifiable IBD (1.9%); 177 patients with IBD (23.3%) presented EIMs, 123 of 544 (22.6%) with UC and 53 of 200 (26.5%) with CD (OR: 0.81, 95% CI: 0.55-1.17, P = 0.31). Regarding the type of EIMs, the articular ones were the most frequent (13.5%), more in CD than in UC (20.0 vs. 11.3%, OR 1.94, 95% CI: 1.25-3.00, P = 0.0037). Patients with IBD and EIMs used more antibodies against tumor necrosis factor (anti-TNFs), compared to those without EIMs (43.5 vs. 18.5%, OR 3.38, 95% CI: 2.31-4.90, P = 0.0001).ConclusionsThe prevalence of EIMs in our cohort is high (23.3%) and the most frequent type is joint. Anti-TNFs are most used when IBD and EIMs coexist. Our study provides valuable information on the association of EIMs and IBD in Latin America.     

Tejido graso epicárdico,calcificación arterial coronaria y mortalidad en pacientes con enfermedad renal crónica avanzada y hemodiálisis

Introduction and objectivesEpicardial and mediastinal adipose tissue (EAT, MAT) are linked to metabolic syndrome and coronary artery disease. Patients with chronic kidney disease (CKD) have thicker EAT. We assessed if EAT and MAT could be associated with increased mortality and cardiovascular events in patients with advanced CKD and haemodialysis therapy.MethodsA post-hoc study was performed. We analyzed a prospective series of 104 cases. EAT thickness was quantified by a multislice synchronized computed tomography (MSCT).ResultsThe follow-up period was 112.68 (109.94 -115.42) months. The optimal cut-off point of EAT for prediction of total mortality was 11.45 mm (92.86% and 43.75%). EAT thickness was associated with serum albumin levels, serum triglyceride levels, phosphorus and calcium phosphate product. The EAT was greater in haemodialysis patients compared to those with advanced CKD (P<.001). Patients with diabetes mellitus had greater EAT and MAT thickness (P=.018). At the end of follow up, the survival average time of patients with EAT thickness <11.45 mm was 97.48 months vs. 76.65 months for thickness > 11.45 mm (P=.007).ConclusionsA higher EAT and MAT thickness was associated with increased mortality. Furthermore, EAT was associated with lower free survival time to fatal and non-fatal cardiovascular events. The measurement of EAT and MAT by MSCT could be a prognostic tool to predict cardiovascular events and mortality risk in advanced CKD patients.

¿Es la obesidad un factor predictivo de falta de respuesta al tratamiento en la artritis psoriásica? Actualización de una revisión sistemática

ObjectivesTo update the study of the association between obesity and treatment response in psoriatic arthritis.MethodsUpdating a systematic review of clinical trials, prospective or retrospective longitudinal studies and case-control studies in psoriatic arthritis in which obesity was assessed as a predictor of efficacy or toxicity. Risks of bias were assessed with validated scales. A meta-analysis of the results of studies with similar outcome variables and weight measurements was performed.ResultsTwenty-one studies were included (6 review of clinical trials, 6 longitudinal studies, 7 registers and one case-control studie), with moderate quality. The risk of achieving an ACR20 response if weight ≥ 100 kg was estimated at OR = 1.42 (1-2.08) and that of withdrawing treatment in an OR of 1.60 (95% CI: 1.34 - 1.92).ConclusionsThere seems to be a greater risk of withdrawal of treatment due to inefficacy and difficulty in achieving remission in patients with psoriatic arthritis if they are obese.     

Prurito en pacientes en diálisis. Revisión de la literatura y nuevas perspectivas

Uremic pruritus (UP) is one of the most uncomfortable symptoms for patients in dialysis. UP has a great impact on dialysis patients’ quality of life and has a great prevalence between those (28–70%). Physiopathology of UP is unknown and usually is unnoticed for most nephrologists (in more than 65% of centers is underdiagnosed). This lack of awareness drives to the unsuccessful treatment of this symptom. Moreover, the fact that most studies have been carried out on small populations and the difficulty assessing UP complicates a correct therapeutical approach. For this reason, we have designed treatment algorithms based on the efficacy of the drugs but also its safeness to avoid adverse effects.     

Calcifilaxis en pacientes con enfermedad renal crónica: una enfermedad todavía desconcertante y potencialmente mortal

Calciphylaxis, also known as calcific uraemic arteriolopathy, is a rare syndrome that typically causes skin necrosis and usually affects dialysis patients. Its pathogenesis is multifactorial and is the consequence of many factors causing ectopic calcifications in patients with chronic kidney disease, such as calcium-phosphate metabolism disorders, hyper- or hypo-parathyroidism, diabetes, obesity, systemic inflammation and the use of vitamin K antagonists, among others. From a clinical point of view, calciphylaxis may progress from painful purpura to extensive areas of skin necrosis that can potentially lead to superinfection and the death of the patient due to sepsis. Treatment is primarily based on managing the wounds, eliminating all the possible precipitating factors of ectopic calcification and administering agents which are capable of inhibiting the process of calcification.     

Impacto pronóstico a largo plazo de la anticoagulación en pacientes en hemodiálisis con fibrilación auricular

Introduction and objectives

Evidence for the efficacy and safety of oral anticoagulation with dicumarines in patients with atrial fibrillation (AF) on hemodialysis is controversial. The aim of our study is to evaluate the long-term prognostic implications of anticoagulation with dicumarines in a cohort of patients with non-valvular AF on a hemodialysis program due to end-stage renal disease.
