RESUMO
BACKGROUND AND OBJECTIVE: Ulcerative colitis (UC) clinical guidelines include the best available evidence, although not all clinical situations are answered, so their management can be controversial. The aim of this study is to identify the situations of mild to moderate UC susceptible to controversy and to evaluate the degree of agreement or disagreement with specific proposals. METHODS: Inflammatory bowel disease (IBD) expert discussion meetings were used to identify criteria, attitudes and opinions regarding the management of UC. A Delphi questionnaire was then developed with 60 items regarding antibiotics, salicylates and probiotics; local, systemic and topical corticosteroids; and immunosuppressants. RESULTS: Consensus was reached in 44 statements (73.3%); 32 in agreement (53.3%) and 12 in disagreement (20.0%). Some of them were: it is not necessary the systematic use of antibiotics despite the severity of the outbreak, being reserved when there is suspicion of infection or systemic toxicity; when faced with a mild-moderate outbreak of UC and in patients who do not respond to aminosalicylates, it is appropriate to use a dose of beclomethasone of 10mg/day for one month and 5mg/day for another month; it is advised that the dose of azathioprine be administered in a single dose. CONCLUSIONS: IBD experts agree on most of the proposals identified for managing mild to moderate UC and there is a need for scientific evidence in some specific situations where expert opinion may be helpful.

Immunosuppressants and immunomodulators are widely used in dermatology. Some of these drugs, however, can increase the risk of severe COVID-19. New antivirals against SARS-CoV-2 have been shown to reduce progression to COVID-19 pneumonia in susceptible patients, but their availability is limited. On May 23, 2022, the Spanish Agency for Medicines and Medical Devices (AEMPS) updated its priority eligibility criteria for SARS-CoV-2 antiviral therapy. In this practical guide, we review the indications for these new drugs and provide guidance on which patients with mild to moderate COVID might benefit from their use in dermatology.

INTRODUCTION: Since the first edition of the Guidelines was published in 2013, much information has been generated around the treatment of ulcerative colitis, and new drugs and action protocols have been introduced. Clinical practice has changed substantially, warranting new approaches and a comprehensive review and update of the evidence. MATERIAL AND METHODS: Once again, we used the GRADE approach, supported by an electronic tool (https://gradepro.org). The clinical scenarios are the same as in the previous version (induction and maintenance in severe and mild-moderate flare-ups), as are the variables and their evaluation. However, in the updated guidelines, three questions have been deleted, 14 added and 30 maintained, making a total of 44 clinical questions. After an exhaustive review of the evidence, the recommendations are now updated. RESULTS: Of the 44 questions analysed, no recommendation could be established in two due to the very low quality of the evidence, while in the other 42, based on different degrees of quality of evidence, recommendations were made according to the GRADE system. In 25 of these questions the final recommendation is strongly in favour, in six strongly against, in seven weakly in favour and in four weakly against. According to the scenarios and recommendations, six algorithms are proposed as a simple guide for practical decision-making. CONCLUSIONS: The aim of this update of the 2013 guidelines is to provide answers, based on the GRADE approach, to the different questions we ask ourselves daily when deciding the most appropriate treatment for our patients with ulcerative colitis in the different clinical scenarios.

INTRODUCTION: Autoimmune hepatitis is a chronic liver disease that impacts on morbidity and mortality of patients. Few epidemiological data exist of this in Latin America and Colombia. OBJECTIVES: The aim of this study is to describe the demographic, clinical and laboratory characteristics of the patients; the treatment and the response to it, the evolution and course of the disease, requirement of liver transplantation and mortality. METHODS: Historical cohort study that include patients attended at an University Hospital in Medellin, Colombia between January 2010 and December 2016 with ≥16 years age at the time of diagnosis of autoimmune hepatitis. Data collection was done from the review of medical records. Statistical analysis was performed using SPSS version 20. RESULTS: The study included 278 patients, 90% of the patients were women, the median age at diagnosis was 50 years. 37.8% were cirrhotic at the time of diagnosis. The biochemical remission was 85%. In patients who developed cirrhosis it was found a higher proportion of men (21.2 vs. 7.8%, p=.027), a greater frequency of overlap autoimmune-primary sclerosant cholangitis (6.0 vs. 0% p=.006) and a greater frequency of non-response to treatment (12.1 vs. 1.6%, p=.004). CONCLUSION: Autoimmune hepatitis is not a rare disease in Colombian population; it predominates in women but has a less favourable course in men. An important number of patients are cirrhotic at the time of diagnosis, the response to treatment and complications in our population are similar to those described worldwide.

HIV-negative immunosuppressed patients comprise a heterogeneous group including transplant patients, patients undergoing treatment with immunosuppressors, uremic patients, alcoholics, undernourished patients, diabetics, patients on dialysis, elderly patients, and those diagnosed with severe or neoplastic processes. Epileptic seizures, focal neurologic signs, and meningoencephalitis are neurologic syndromes that require urgent action. In most of these situations, neuroimaging tests are necessary, but the findings can be different from those observed in immunocompetent patients in function of the inflammatory response. Infectious disease is the first diagnostic suspicion, and the identification of an opportunistic pathogen should be oriented in function of the type and degree of immunosuppression. Other neurologic emergencies include ischemic stroke, cerebral hemorrhage, neoplastic processes, and pharmacological neurotoxicity. This article reviews the role of neuroimaging in HIV-negative immunodepressed patients with a neurologic complication that requires urgent management.

Inflammatory bowel disease is a chronic disorder of unknown aetiology that results from a pathologic response from both the innate and acquired immune systems, leading to chronic inflammation of the gastrointestinal tract. New drugs have been introduced into the therapeutic armamentarium of inflammatory bowel disease but are not effective in all patients; moreover, among initial responders, there have been reports of loss of response over time. In addition, these drugs sometimes have adverse effects and are often expensive. The present article reviews the studies presented at Digestive Disease Week 2016 that provided new data on the optimisation of currently approved treatments for inflammatory bowel disease, experience with recently approved drugs in clinical practice, and some studies on molecules that are under development for the treatment of these diseases.

Numerous studies were presented in Digestive Disease Week 2015 (DDW 2015) on the natural history, complications, and safety of treatments in inflammatory bowel disease (IBD), as well as novel findings on fertility, pregnancy, and breastfeeding. The present article reviews presentations on the natural history of IBD, the risk of complications and their prevention, treatment safety, aspects related to fertility, pregnancy, and breastfeeding, as well as the risk of cancer and its association with IBD and with drugs used in its treatment. In the next few years, more data will become available on treatment safety and the possible complications that can develop in IBD patients due to the disease itself and the drugs employed in its treatment, which will allow measures to be adopted to improve prognosis.

Idiopathic nephrotic syndrome is the most common glomerular disease in childhood, affecting 1 to 3 per 100,000 children under the age of 16. It most commonly occurs in ages between 2 and 10. Its cause is unknown, and its histology corresponds to minimal change disease in 90% of cases, or focal segmental glomerulosclerosis. Steroid-resistant nephrotic syndrome represents 10-20% of idiopathic nephrotic syndrome in pediatrics. It has a poor prognosis, and its management is a significant therapeutic challenge. Half of patients evolve to end-stage renal disease within 5 years, and are additionally exposed to complications secondary to persistent NS and to the adverse effects of immunosuppressive therapy. The primary goal of treatment is to achieve complete remission, but even a partial remission is associated with a better renal survival than the lack of response. This paper is the result of the collaborative effort of the Nephrology Branch of the Chilean Society of Pediatrics with aims at helping pediatricians and pediatric nephrologists to treat pediatric idiopathic nephrotic syndrome. In this second part, handling of steroid-resistant nephrotic syndrome as well as nonspecific therapies are discussed.

The objective of this article is to summarize reports presented at Digestive Disease Week 2014 that relate to fertility and pregnancy, inflammatory bowel disease in elderly patients, the risk of cancer and its relationship to treatment and finally, developments regarding psychological aspects that may affect patients with inflammatory bowel disease. Studies were selected at the discretion of the author, mainly considering those with conclusions that can be applied immediately to clinical practice. Using anti-TNF drugs during pregnancy is safe in the short term. This currently seems to be true for the medium and the long term. To limit fetal exposure, the mother can safely stop taking the anti-TNF drugs in the second trimester of the pregnancy if she is in remission. Elderly patients with inflammatory bowel disease require stricter monitoring than younger patients due to the risk of complications, especially infections associated with the disease and treatments. The effect of inflammatory bowel disease and the drugs for its treatment on the risk of development is still not well established, but the magnitude of the effect seems possibly lower than previously described. The causal link between psychological factors and the occurrence of IBD relapse is by no means established.

Bullous pemphigoid (BP) is an autoimmune subepidermal bullous disease in which autoantibodies are directed against components of the basement membrane. Most of these antibodies belong to the immunoglobulin G class and bind principally to 2 hemidesmosomal proteins: the 180-kD antigen (BP180) and the 230-kD antigen (BP230). It is the most common blistering disease in the adult population in developed countries, with an estimated incidence in Spain of 0.2 to 3 cases per 100,000 inhabitants per year. The disease primarily affects older people, although it can also occur in young people and even in children. In recent years, advances in clinical practice have led to a better understanding and improved management of this disorder. These advances include new diagnostic techniques, such as enzyme-linked immunosorbent assay for BP180 and new drugs for the treatment of BP, with diverse therapeutic targets. There is, however, still no international consensus on guidelines for the management of BP. This article is an updated review of the scientific literature on the treatment of BP. It focuses primarily on evidence-based recommendations and is written from a practical standpoint based on experience in the routine management of this disease.

OBJECTIVE: The objective of this review is to gather the available evidence on the different drugs used in immune-mediated inflammatory diseases in pregnancy, lactation, their influence on female and male fertility, advice on discontinuation before conception and to help in routine clinical practice for better patient advice on family planning. METHODS: A bibliographic search was carried out, where published articles (review studies, observational studies and case series) in English or Spanish until April 2020 that analyzed the management of pregnancy, lactation and/or fertility in patients on treatment in immune-mediated diseases were selected. RESULTS: A total of 95 references were selected and the information on each drug was synthesized in tables. Drugs contraindicated in pregnancy are topical retinoids, pimecrolimus, cyclooxygenase 2 inhibitors, methotrexate, mycophenolate mofetil, leflunomide, acitretin, and thiopurines. The lack of data advises against the use of apremilast, tofacitinib, baricitinib, anakinra, abatacept, tocilizumab and the new biologicals. Topical salicylates, paracetamol, ultraviolet therapy and hydroxychloroquine treatment are safe, and anti-TNF biological therapy are considered low risk, with certolizumab being the drug of choice throughout pregnancy and lactation. Most are compatible with paternal exposure except for sulfasalazine, mycophenolate and leflunomide, for which suspension of treatment prior to conception is recommended, and cyclosporine with dose requirements of less than 2mg/kg/day. CONCLUSIONS: In this context of chronic treatments with teratogenic potential, it is necessary to highlight the importance of pregnancy planning to select the safest drug. Given the quality of the available data, it is still necessary to continuously update the information, as well as to promote observational studies of cohorts of pregnant patients and men of childbearing age, including prospective studies, in order to generate more scientific evidence.

The number of people with immunosuppression is increasing considerably due to their greater survival and the use of new immunosuppressive treatments for various chronic diseases. This is a heterogeneous group of patients in whom vaccination as a preventive measure is one of the basic pillars of their wellbeing, given their increased risk of contracting infections. This consensus, developed jointly by the Sociedad Española de Infectología Pediátrica (Spanish Society of Pediatric Infectious Diseases) and the Advisory Committee on Vaccines of the Asociación Española de Pediatría (Spanish Association of Paediatrics), provides guidelines for the development of a personalised vaccination schedule for patients in special situations, including general recommendations and specific recommendations for vaccination of bone marrow and solid organ transplant recipients, children with inborn errors of immunity, oncologic patients, patients with chronic or systemic diseases and immunosuppressed travellers.

OBJECTIVE: Cogan's syndrome (CS) is an inflammatory disease classified as variable vessel vasculitis. It is a rare disease with few published series, and therefore we reviewed our experience in the last ten years in two centres. MATERIALS AND METHODS: Description of 7 diagnosed cases of CS, according to the classification criteria (typical or atypical), their clinical manifestations, treatments used and their complications. A comparative analysis was performed with the series and cases described in the literature. RESULTS: Seven cases were included, three men and four women, with a mean age at diagnosis of 43 years, and an average disease duration of 47 months. Five patients met the typical characteristics according to the 1980 classical criteria, the rest being atypical cases, one due to the absence of interstitial keratitis and another due to a period between the onset of ocular and auditory-vestibular clinical symptoms greater than two years. All received immunosuppressants, methotrexate being the most commonly used, followed by azathioprine. In 5 cases, biological drugs were used, infliximab in 4 times and 2 tocilizumab. One patient died from bacterial endocarditis and septic shock. CONCLUSION: The characteristics of the series presented are like those published to date, with clinical differences mainly in the involvement of large vessels. Given the low frequency, it seems necessary to create multicentre records to improve the evidence regarding the management of patients with CS.
RESUMO
Kidney transplantation is the renal replacement therapy of choice in patients with end-stag ekidney disease. Immunosuppressive drugs are the main pillar of treatment in solid organ transplantation as they reduce rejection rates and increase graft survival. However, they can also cause significant side effects that can complicate transplant progression. The objective of this chapter is to outline the main characteristics of immunosuppressantsagents, their mechanisms of action and the side effects.
El tratamiento de elección en los pacientes con enfermedad renal avanzada es el trasplante renal. Los fármacos inmunosupresores constituyen el pilar fundamental de la terapia en el trasplante de órgano sólido, ya que permiten disminuir las tasas de rechazo y aumentar la supervivencia del injerto. Sin embargo, también pueden provocar efectos adversos que pueden complicar la evolución del trasplante. El objetivo de este capítulo es exponer las características de los principales inmunosupresores, sus mecanismos de acción y principales efectos secundarios.

Coronavirus disease 2019 (COVID-19) is a serious respiratory illness caused by SARS-CoV-2. There is controversy about whether their immunosuppressive status is a risk factor or a protective factor for developing severe disease. We report herein the clinical outcome of three family members that had COVID-19 infection, presenting with and without different risk factors that have been described in more severe disease. Paradoxically, the patient with more risks of developing a severe disease, a 64-year-old woman, 2-years liver transplant recipient under treatment with tacrolimus, presented a similar outcome compared to the two other members of the family. She showed shorter hospitalization time, similar clinical outcome with fewer oxygen needs. The present clinical observation raises the question about the possible beneficial effect of tacrolimus in patients with COVID-19. Indeed, tacrolimus (FK-506) have an inhibitory effect on human coronaviruses by: 1) an antiviral effect by binding to the FK-506-binding proteins (FKBP) with a subsequent inhibition of their peptidyl-prolyl cis/trans isomerase (PPIase) activity, which seems to be important for the coronavirus life cycle; and 2) regulating the immune response by the inhibition of the activity of the nuclear factor of activated T-cells (NFAT) required for immunosuppression. The present observation states that liver recipients' patients with COVID-19 may not have worse outcomes when compared with other patients that have COVID-19 risk factors and puts in evidence the two mechanisms related to tacrolimus.

INTRODUCTION: The COVID-19 pandemic is changing approaches to diagnosis, treatment, and care provision in multiple sclerosis (MS). During both the initial and peak phases of the epidemic, the administration of disease-modifying drugs, typically immunosuppressants administered in pulses, was suspended due to the uncertainty about their impact on SARS-CoV-2 infection, mainly in contagious asymptomatic/presymptomatic patients. The purpose of this study is to present a safety algorithm enabling patients to resume pulse immunosuppressive therapy (PIT) during the easing of lockdown measures. METHODS: We developed a safety algorithm based on our clinical experience with MS and the available published evidence; the algorithm assists in the detection of contagious asymptomatic/presymptomatic cases and of patients with mild symptoms of SARS-CoV-2 infection with a view to withdrawing PIT in these patients and preventing new infections at day hospitals. RESULTS: We developed a clinical/microbiological screening algorithm consisting of a symptom checklist, applied during a teleconsultation 48hours before the scheduled session of PIT, and PCR testing for SARS-CoV-2 in nasopharyngeal exudate 24hours before the procedure. CONCLUSION: The application of our safety algorithm presents a favourable risk-benefit ratio despite the fact that the actual proportion of asymptomatic and presymptomatic individuals is unknown. Systematic PCR testing, which provides the highest sensitivity for detecting presymptomatic cases, combined with early detection of symptoms of SARS-CoV-2 infection may reduce infections and improve detection of high-risk patients before they receive PIT.

INTRODUCTION: Progressive multifocal leukoencephalopathy is a demyelinating disease of the central nervous system caused by the reactivation of the JC virus. This opportunistic encephalopathy mainly affects immunodepressed patients with stage III HIV infection, although in recent years it has also been found in association with treatment with immunosuppressors such as natalizumab. MRI plays an important role in both the early diagnosis and follow-up of this disease. Recently, it has been reported that hypointensities in U-fibers and cortex adjacent to white-matter lesions characteristic of the disease can be identified on T2-weighted gradient-echo and susceptibility-weighted sequences in patients with progressive multifocal leukoencephalopathy. OBJECTIVE: We aimed to analyze the presence and usefulness of cortical hypointensity on T2-weighted gradient-echo sequences in relation to the diagnosis of progressive multifocal leukoencephalopathy and to review the literature on the topic. MATERIAL AND METHODS: We analyze three cases of progressive multifocal leukoencephalopathy seen at our center in three patients with immunosuppression of different origins: one with stage III HIV infection, one with multiple sclerosis being treated with natalizumab, and one with rheumatoid arthritis being treated with rituximab. RESULTS: In all three cases MRI showed the cortical hypointensity adjacent to the white-matter lesion in the T2-weighted gradient-echo sequence. In the patient with multiple sclerosis, this sign appeared earlier than the abnormal signal in the white matter. The patient being treated with rituximab was diagnosed postmortem and the pathology findings correlated with the MRI findings. CONCLUSION: The finding of cortical hypointensity on T2-weighted gradient-echo MRI sequences seems to support the diagnosis of progressive multifocal leukoencephalopathy, regardless of the type of immunosuppression, so this finding should routinely assessed in patients suspected of having this disease.

BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin disease that typically affects children. Severe forms may have a profound effect on patients' quality of life. Some forms are resistant to conventional treatment and require the use of systemic immunosuppressants such as azathioprine (AZA) to adequately manage the disease. OBJECTIVE: To evaluate the effectiveness and tolerance of AZA in children with severe AD. PATIENTS AND METHODS: We performed a retrospective study of children with severe AD treated with AZA between January 2007 and May 2017. RESULTS: We reviewed the cases of 11 patients (6 boys and 5 girls) with a mean age of 13 years (range, 8-18 years). The mean (SD) age at start of treatment was 10.9 (2.2) years (95% CI 8.6-13.1). The mean initial dosage of AZA was 1.8 (0.2) mg/kg/d. We evaluated treatment response after 4 weeks, 12 to 16 weeks, and 6 months. Mean treatment duration was 10.8 (5.7) months. Treatment had to be suspended in 2 patients because of adverse effects. Seven of the 9 remaining patients presented complete or almost complete clearance of the AD after 6 months of treatment. CONCLUSION: In our experience, AZA is well tolerated and may be considered as a treatment option in children with severe AD resistant to conventional treatment.

OBJECTIVE: The treatment of noninfectious uveitis includes steroids and immunomodulatory drugs, the use of which has increased in the last few years, and the options have been enriched with the development of new treatments. However, clear therapeutic guidelines and protocols have not been developed. The purpose is to analyze the response to the drugs used and the characteristics of the patients treated at a multidisciplinary uveitis clinic. MATERIAL AND METHODS: Observational and retrospective study of the patients attended to from January 2012 to December 2015. Infectious, posttraumatic and postoperative uveitis, as well as masquerade syndrome, were excluded. RESULTS: Two hundred six patients were included. Overall, 58.80% had uveitis without association of systemic disease, mostly idiopathic uveitis, and 35.65% had uveitis with systemic involvement, mainly related to spondyloarthritis. Uveitis without systemic association and anterior uveitis achieved disease control with local treatment more frequently than others (p=.002 and p <.001, respectively). In all, 49.76% of the patients required systemic treatment. Among those treated with immunomodulators, 53.26% needed a second drug and 31.52% needed a third drug. Women required immunomodulators more often than men (P=.042). Methotrexate was the most widely used immunomodulator. Posterior uveitis responded less favorably to the second immunomodulator than anterior uveitis (p=.006). CONCLUSIONS: Almost half of the patients needed an immunomodulatory drug and some of them required successive drug changes. Intermediate uveitis was the most treatment-refractory uveitis.
