Opciones terapéuticas en pacientes con diabetes mellitus post trasplante (dmpt)

La diabetes mellitus postrasplante (DMPT) es una complicación que se encuentra de forma frecuente y se sucede al trasplante de órganos. Existen factores predisponentes a esta complicación, son varios y pueden estar presentes en el pretrasplante, peritrasplante o ya en el pos trasplante; dentro de estos, se resaltan las terapias inmunosupresoras asociadas. La importancia clínica de DMPT radica en su impacto para la enfermedad cardiovascular (ECV) y enfermedad renal crónica (ERC). En el presente artículo hacemos una revisión de las intervenciones tradicionales y las nuevas terapias para el manejo y tratamiento de la DMPT.

Post-transplant diabetes mellitus (PTDM) is a frequent complication after organ transplantation. There are several predisposing factors for this complication, which may be present in the pre-transplant, peri-transplant, or already post-transplant; within these, associated immunosuppressive therapies will be highlighted. The clinical importance of DMPT lies in its impact on cardiovascular disease (CVD) and chronic kidney disease (CKD). In this article, we review traditional interventions and new therapies for managing and treating PTDM.

Immune Deficiency/Dysregulation Associated Lymphoid Proliferations, EBV+ In Persons Living With HIV

ABSTRACT Background: The 5th edition of the World Health Organization Classification of Hematolymphoid Tumors recently defined immune deficiency/dysregulation (IDD)-associated-lymphoid-proliferations in HIV settings, where information is scarce, often gone under or misdiagnosed. Objectives: To describe the clinical picture, histopathology, and outcomes of IDD-associated-lymphoid-proliferations Epstein-Barr virus+ (EBV) in people living with HIV without organ transplantation, antiretroviral therapy (ART) treated. Methods: HIV+ patients diagnosed with IDD-associated-lymphoid-proliferations seen at an academic medical center in Mexico from 2016 to 2019 were included. Immunohistochemical studies, in situ hybridization, and polymerase chain reaction analysis for EBV and LMP1 gene deletions were performed and correlated with clinical data. Results: We included 27 patients, all men who have sex with men, median age 36 years (interquartile range [IQR] 22-54). The median baseline CD4+ T cells were 113/mL (IQR 89-243), the CD4+/CD8+ ratio was 0.15 (IQR: 0.09-0.22), and the HIV viral load was 184,280 copies/mL (IQR: 76,000-515,707). Twenty patients (74.07%) had IDD-associated-lymphoid-proliferations hyperplasia plasma cell type EBV+, 3 (11.1%) had hyperplasia mononucleosis-like type (IM-type), 1 patient (3.70%) had florid follicular hyperplasia, 3 (11.1%) IDD-associated-lymphoid-proliferations polymorphic type, and there were 22 cases (81.4%) of synchronic Kaposi Sarcoma. Two patients were diagnosed with Hodgkin lymphoma following a second positron emission tomography-computed tomography scan-guided biopsy. The median follow-up was 228 weeks (IQR 50-269); 6 patients died (22.2%) of causes unrelated to IDD-associated-lymphoid-proliferations related. Conclusion: IDD-associated-lymphoid-proliferations EBV+ occured in severely immunosuppressed HIV+ patients, a high percentage of whom had concomitant Kaposi sarcoma. The prognosis was good in patients treated only with ART.

Criptococosis Meníngea en pacientes viviendo con HIV experiencia en cuidados intensivos / Meningeal cryptococcosis in patients living with HIV. Experience in intensive care

Resumen Introducción : La criptococosis meníngea (CM) es una causa frecuente de meningoencefalitis en personas que viven con HIV (PVHIV) y produce una importante morbi-mortalidad (20-55%). Se describen las características clínicas, la letalidad y las variables de mal pronóstico en PVHIV con CM, en unidades de cuidados intensivos (UCI). Métodos : Estudio observacional y retrospectivo. Pe ríodo 21/11/2006 a 24/05/2023. Población evaluada: 154 PVHIV adultos, admitidos en UCI con diagnóstico de CM. Los porcentajes y valores absolutos, fueron comparados mediante Chi-Cuadrado o test de Fisher y las medianas mediante test de Mann-Whitney. La asociación con mortalidad se evaluó por regresión logística. Se utilizó el programa SPSS 23.0. Un valor p<0.05 fue considerado significativo. Resultados : Los pacientes que fallecieron y los que so brevivieron fueron comparables en edad y sexo (p>0.05). El análisis univariado, observó que un estado funcional y nutricional alterado, falta de tratamiento antirretroviral previo (TARV), CD4 <100 células/μl, APACHE II ≥13 y un score pronóstico de PVHIV ≥8 puntos, requerir ventilación mecánica (VM), sufrir insuficiencia respiratoria, renal, disfunción neurológica o sepsis, podrían estar asociados (p<0.05) con mortalidad. La regresión logística estableció que un estado funcional y nutricional alterado, un score pronóstico PVHIV ≥8, necesitar VM y sufrir sepsis serían variables independientes asociadas a mortalidad. Conclusión : Los resultados indican que el estado funcional y nutricional alterado, un score pronóstico PVHIV ≥8 puntos, requerir VM y sufrir sepsis al ingreso a UCI podrían servir como variables independientes para predecir un mayor riesgo de mortalidad.

Abstract Introduction : Meningeal cryptococcosis (MC) is a frequent cause of meningoencephalitis in people living with HIV (PLHIV), leading to substantial morbidity (20- 55%). Clinical characteristics, lethality and adverse prog nostic factors in PLHIV with MC admitted to intensive care units (ICUs) are described. Methods : A retrospective observational study. Period from 11/21/2006 to 05/24/2023. It involved 154 adult PLHIV diagnosed with MC and admitted to ICUs. Percen tages and absolute values were compared by Chi-Square or Fisher's test and medians by Mann-Whitney test. The association with mortality was assessed by logistic re gression. SPSS 23.0 software was used. A p-value <0.05 was considered significant. Results : Patients who died and those who survived were comparable in age and sex (p>0.05). Univariate analysis showed that impaired functional and nutritio nal status, lack of previous highly active antiretroviral therapy, CD4 <100 cells, APACHE II ≥13 and a PLHIV prognostic score ≥8 points, requiring mechanical venti lation (MV), respiratory failure, renal failure, neurological dysfunction or sepsis could be associated (p<0.05) with mortality. Logistic regression established that impaired functional and nutritional status, a PLHIV prognostic score ≥8, need for MV and presence of sepsis would be independent variables associated with mortality. Conclusion : The results indicate that altered functio nal and nutritional status, a PLHIV prognostic score ≥ 8 points, requiring MV and suffering sepsis on admission to the ICU are more frequent in deceased patients, and they could therefore serve as independent variables to predict a higher risk of mortality.

Elevated serum IL-6 levels predict treatment interruption in patients with moderate to severe psoriasis: a 6-year real-world cohort study

Abstract Background: Real-world, primary data on the treatment of psoriasis are scarce, especially concerning the role of soluble biomarkers as outcome predictors. Objective: The authors evaluated the utility of Th1/Th17 serum cytokines along with clinical characteristics as predictors of drug survival in the treatment of psoriasis. Methods: The authors consecutively included participants with moderate to severe psoriasis who were followed up for 6 years. Baseline interferon-α, tumor necrosis factor-α, and inter-leukin (IL)-2, IL-4, IL-6, IL-10, and IL-17A were measured using a cytometric bead array; clinical data were assessed. The authors calculated hazard ratios (HRs) for drug survival using a Cox proportional hazards model. Results: The authors included 262 patients, most of whom used systemic immunosuppressants or biologics. In the multivariate model, poor quality of life measured by the Dermatology Life Quality Index (HR = 1.04; 95% CI 1.01-1.07; p = 0.012) and elevated baseline IL-6 (HR = 1.99; 95% CI 1.29-3.08; p = 0.002) were associated with treatment interruption. Study limitations: The main limitation of any cohort study is the presence of confounders that could not be detected in clinical evaluation. Conclusions: Poor quality of life and elevated baseline serum IL-6 level predicted treatment interruption in patients with moderate to severe psoriasis. Although IL-6 is not the most important mediator of the inflammatory pathway in the skin environment, it is an interesting biomarker candidate for predicting psoriasis treatment response.

Research progress on T lymphocyte subsets in immunosuppression of sepsis in children / 中国小儿急救医学

Although a great deal of research has been done on sepsis in children，its pathogenesis remains controversial and unresolved，one of which is immune dysfunction.Immunosuppression is the core part of immune dysfunction，and it is related to the disease progression，treatment options，and prognosis changes in patients with sepsis.Since T lymphocytes play a crucial role in immune function，they have been regarded as an important indicator for judging changes in immune function in clinical practice.This review explained the mechanism of immunosuppression caused by some T lymphocyte subsets and its clinical application value in the evaluation，prognosis and immune intervention of sepsis.

Endoplasmic reticulum stress(ERS)is a subcellular pathological state formed by imbalance of environment in endoplasmic reticulum,and is regarded as an important pathway that mediates apoptosis.Recent studies have found that after ERS occurs in various immune tissues and cells,immunosuppressive effect that produced is involved in regulating body's immune homeo-stasis,affecting occurrence,outcome and prognosis of many diseases.This article reviews production of ERS,signal regulation and pathophysiological changes in immune organs and immune cells,and its role in development of inflammatory diseases and tumors.

Research advances of myeloid-derived suppressor cells mediated by programmed death-1/programmed death-ligand 1 pathway in sepsis-induced immunosuppression / 中华危重病急救医学

Sepsis is a life-threatening organ dysfunction due to dysregulation of the body's response to infection. The immunosuppressive phase of sepsis is also an important cause of high morbidity and mortality in patients with advanced sepsis. Myeloid-derived suppressor cell (MDSC), as a heterogeneous population of Gr1 +CD11b + immature cells, play a pivotal role in the immune process of advanced sepsis together with programmed death-1 (PD-1) and programmed death-ligand 1 (PD-L1) with immunosuppressive properties. This review summarized the research progress of PD-1/PD-L1 pathway-mediated mechanism of MDSC in septic immunosuppression in recent years. The mechanism of action of PD-1/PD-L1 pathway in the immunosuppressive stage, the effects of PD-1/PD-L1 pathway on the "dual-signaling" model of MDSC through the signaling pathway and cytokines, as well as the time course of PD-1/PD-L1 pathway mediation in sepsis were described.

Research progress on oral lichenoid drug reactions / 口腔疾病防治

@#Oral lichenoid drug reactions (OLDRs) are inflammatory reactions of the oral mucosa caused by the use of specific drugs in sensitive individuals and are classified as oral lichenoid lesions (OLLs). Its clinical and pathological manifestations do not have significant specificity compared to other types of OLL. Various types of drugs have been reported to induce OLDR, including antihypertensive drugs, nonsteroidal anti-inflammatory drugs, hypoglycemic drugs, antipsychotics, and immunosuppressants, among other drugs. Apart from local or systemic administrate glucocorticoids, the most effective treatment measure is to stop using suspicious drugs. Most patients can achieve significant relief from mucosal ulcers and erosion, but white lines may still remain. OLDR has been widely reported in the literature. However, due to a lack of systematic understanding, we do not have a recognized standard for the diagnosis and treatment of this disease. There are still doubts about the causal relationship between related drugs and oral lichen-like lesions. In response to the abovementioned problems, we searched the literature on drug-related oral lichen planus and lichen-like lesions at home and abroad over the past 20 years, most of which were case reports and only a few of which were case-control studies. This article describes the current research status of lichenoid lesions from four perspectives: concepts, suspicious drugs, clinical and pathological manifestations, and treatment prognosis. We hope to provide a theoretical reference for the prevention, diagnosis, and clinical treatment of related lichenoid lesions. A literature review demonstrated that there are still many unclear issues related to the etiology, pathogenesis, clinical diagnosis and treatment, treatment prognosis, and other aspects of this disease, and further clinical and basic research is needed for in-depth exploration.

Research progress in adult liver retransplantation / 器官移植

Liver retransplantation is the final option for graft failure after liver transplantation. The interval between the first and second liver transplantation will directly affect surgical indications, technical difficulties and treatment outcomes of adult liver retransplantation. Previous studies have shown that the overall survival of liver allografts and recipients after liver retransplantation is significantly lower than that after the first liver transplantation. However, with comprehensive progress in organ preservation methods, anesthesia management concepts, intensive care strategies, surgical techniques and new immunosuppressive drugs, clinical efficacy of adult liver retransplantation has been significantly improved. In this article, the changes of indications, timing of operation, long-term efficacy and its influencing factors, technical difficulties, selection of immunosuppressive regimens and the implementation of living donor liver retransplantation were reviewed, and the achievements, challenges and potential solutions of adult liver retransplantation were summarized, aiming to provide reference for enhancing clinical efficacy of adult liver retransplantation.

Effect of early immunotherapy in preventing conversion of ocular myasthenia gravis to generalized myasthenia gravis / 西安交通大学学报(医学版)

【Objective】 To compare the risk of generalization in patients with ocular myasthenia gravis (OMG) receiving or not receiving immunosuppressive treatment. 【Methods】 The data of patients with OMG registered in Tangdu Hospital of Air Force Military Medical University from January 1, 2015 to May 1, 2019 were reviewed; the patients were divided into treatment group and control group according to whether they had received immunosuppressive treatment. The multivariate Cox proportional hazards regression model analysis was used to compare the risk of generalization between the two groups of patients within 2 years of onset. Sensitivity analysis was used to evaluate the duration of immunosuppressive treatment and the risk of generalization under different immunotherapy regimens. By using stratified analysis, the consistency of the main results across different levels of subgroup factors was evaluated. 【Results】 A total of 702 OMG patients were collected. Of them 367 patients (52.3%) were included in the treatment group, with an average onset age of (50.54±15.1) years, and 159 (43.3%) being female. Another 335 patients (47.7%) were included in the control group, with an average age of (49.1±14.6) years, and 159 ones (47.5%) were female. A total of 28 cases (7.7%) in the treatment group and 106 cases (31.6%) in the control group developed generalization during the observation period. After multivariate-adjusted Cox model analysis, patients who had received immunosuppressive treatment had a significantly lower risk of generalization compared with the control group (HR=0.24; 95% CI: 0.15-0.37; P<0.001). Sensitivity analysis found that the longer the duration of immunosuppression, the lower the risk of generalization (HR=0.88; 95% CI: 0.85-0.91; P<0.001). Stratified analysis showed that immunosuppressive therapy reduced the risk of generalization in different subgroups of patients. 【Conclusion】 Early immunosuppressive treatment can significantly reduce the risk of generalization in patients with OMG.

Latest research progress in airway stenosis after lung transplantation / 器官移植

With the optimization of surgical technologies and postoperative management regimens, the number of lung transplantation has been significantly increased, which has become an important treatment for patients with end-stage lung disease. However, due to the impact of comprehensive factors, such as bronchial ischemia and immunosuppression, the incidence of airway stenosis after lung transplantation is relatively high, which severely affects postoperative survival and quality of life of lung transplant recipients. In recent years, with the improvement of perioperative management, organ preservation and surgical technologies, the incidence of airway stenosis after lung transplantation has been declined, but it remains at a high level. Early diagnosis and timely intervention play a significant role in enhancing clinical prognosis of patients with airway stenosis. In this article, the general conditions, diagnosis, treatment and prevention of airway stenosis after lung transplantation were reviewed, aiming to provide reference for comprehensive management of airway stenosis after lung transplantation and improving clinical prognosis of lung transplant recipients.

Application of xenotransplantation in clinical practice / 器官移植

Organ transplantation is the optimal treatment for end-stage organ failure. Nevertheless, organ shortage is a global problem, which limits further development of organ transplantation. Recent research shows that genetically modified pig may become a realistic alternative source of clinical organ transplantation donor. Xenotransplantation may serve as one of the effective measures to resolve the problem of organ shortage. Since 2021, 2 cases of living xenotransplantation and 6 cases of xenotransplantation in brain death recipients have been performed worldwide, and phase Ⅰ clinical trial of xenotransplantation has been launched, and the results have exceeded expectations. Therefore, in this article, recent clinical trial results of xenotransplantation in living and brain death recipients were retrospectively analyzed, and scientific, technical and ethical issues related to clinical research of xenotransplantation were illustrated, hoping to provide reference for clinical research of xenotransplantation in China and promote the development of xenotransplantation in clinical practice.

Application of metagenomic next-generation sequencing in prevention and control of infection in solid organ transplantation / 器官移植

Organ transplantation has become an effective treatment for multiple end-stage diseases. However, the recipients of organ transplantation need to take immunosuppressive drugs for a long time after operation, which leads to low immune function and relatively high incidence of bacterial, viral and fungal infections. Traditional microbial detection methods, such as pathogen culture, immunological detection and polymerase chain reaction, have been widely applied in infection detection, whereas these methods may cause problems, such as long detection time and presumed pathogens. Metagenomic next-generation sequencing has been widely adopted in infection prevention and control in organ transplantation in recent years due to high detection rate and comprehensive detection of pathogen spectrum. In this article, the application of metagenomic next-generation sequencing in the prevention and control of infection in solid organ transplantation was reviewed, aiming to provide reference for the diagnosis and treatment of transplantation-related infection.

Optimal diagnosis and treatment for renal allograft fibrosis / 器官移植

Renal allograft fibrosis is one of the common and severe complications after kidney transplantation, which seriously affects the function and survival rate of renal allograft, and may even lead to organ failure and patient death. At present, the researches on renal allograft fibrosis are highly complicated, including immunity, ischemia-reperfusion injury, infection and drug toxicity, etc. The diagnosis and treatment of renal allograft fibrosis remain extremely challenging. In this article, the latest research progress was reviewed and the causes, novel diagnosis and treatment strategies for renal allograft fibrosis were investigated. By improving diagnostic accuracy and optimizing treatment regimen, it is expected to enhance clinical prognosis of kidney transplant recipients, aiming to provide reference for clinicians to deliver proper management for kidney transplant recipients.

Strategies for ABO-incompatible liver transplantation / 器官移植

With rapid development of organ transplantation, the issue of global organ shortage has become increasingly prominent. At present, liver transplantation is the most effective treatment for end-stage liver disease. Nevertheless, the shortage of donors has been a key problem restricting the development of liver transplantation. China is a country with a larger number of hepatitis B, and the shortage of donor liver is particularly significant. Many critically ill patients often lose the best opportunity or even die because they cannot obtain a matched donor liver in time. As a strategy to expand the donor pool, ABO-incompatible (ABOi) liver transplantation offers new options for patients who are waiting for matched donors. However, ABOi liver transplantation is highly controversial due to higher risk of complications, such as severe infection, antibody-mediated rejection (AMR), biliary complications, thrombotic microangiopathy, and acute kidney injury, etc. In this article, research progress in preoperative, intraoperative and postoperative strategies of ABOi liver transplantation was reviewed, aiming to provide reference for clinical application and research of ABOi liver transplantation.

Expert views on screening for tuberculosis infection in patients commencing treatment with a biologic agent

ABSTRACT Objective: Many biologic agents cause some degree of immunosuppression, which can increase the risk of reactivation of tuberculosis infection (TBI). This risk is variable between individual biologics. We aimed to assess current (and recommended) clinical practice of TBI screening and treatment among patients initiating treatment with biologic agents. Methods: An online questionnaire was distributed via email to members of the Global Tuberculosis Network and associated professional organisations to seek insights into the screening for and treatment of TBI in patients treated with biologics. Results: A total of 163 respondents in 27 countries answered at least one question. For all biologics described in the questionnaire, respondents advised increasing screening relative to current practice. Observed and supported TBI screening rates in patients treated with TNF-a inhibitors were high, especially for older TNF-a inhibitors. Most participants supported TBI screening in patients treated with B- or T-cell inhibitors but not in those treated with interleukin inhibitors. Guideline awareness was higher for TNF-a inhibitors than for other biologic classes (79% vs. 34%). Conclusions: Although respondents stated that TBI screening rates are lower than what they consider ideal, there was a tendency to recommend TBI screening in patients treated with biologics not known to be associated with an increased risk of TBI. As a result, there is a potential risk of over-screening and over-treatment of TBI, potentially causing harm, in patients treated with biologics other than TNF-a inhibitors. There is a need to research the risk of TBI associated with biologics and for guidelines to address the spectrum of TBI risk across all types of biologics.

Susceptibility of solid organ transplant recipients to viral pathogens with zoonotic potential: A mini-review

ABSTRACT A substantial number of zoonotic diseases are caused by viral pathogens, representing a significant menace to public health, particularly to susceptible populations, such as pregnant women, the elderly, and immunocompromised individuals. Individuals who have undergone solid organ transplantation frequently experience immunosuppression, to prevent organ rejection, and, thus are more prone to opportunistic infections. Furthermore, the reactivation of dormant viruses can threaten transplant recipients and organ viability. This mini-review examines the up-to-date literature covering potential zoonotic and organ rejection-relevant viruses in solid organ transplant recipients. A comprehensive list of viruses with zoonotic potential is highlighted and the most important clinical outcomes in patients undergoing transplantation are described. Moreover, this mini-review calls attention to complex multifactorial events predisposing viral coinfections and the need for continuous health surveillance and research to understand better viral pathogens' transmission and pathophysiology dynamics in transplanted individuals.

Contagem Absoluta de Linfócitos: um Preditor de PCR Sérica Positiva para o Trypanosoma cruzi em Pacientes com Chagas Submetidos ao Transplante Cardíaco / Absolute Lymphocyte Count: a Predictor of Positive Serum PCR for Trypanosoma cruzi in Patients with Chagas Disease Undergoing Heart Transplantation

Resumo Fundamento É desconhecido se a linfopenia é fator de risco para a reativação da doença de Chagas no transplante cardíaco (TxC), como recentemente descrito na reativação de citomegalovírus em pacientes transplantados. Objetivo Avaliar se a linfopenia no perioperatório do TxC está relacionada à parasitemia precoce pelo Trypanosoma cruzi. Métodos Amostra analisada (janeiro de 2014 a janeiro de 2023) em estudo observacional e retrospectivo. A parasitemia foi avaliada nos primeiros 3 meses após o TxC por meio da reação em cadeia da polimerase sérica (PCR) e comparada com a contagem total de linfócitos no perioperatório do TxC por curvas ROC. Comparadas características de base com a PCR Chagas por modelos de risco proporcionais de Cox independentes. Nível de significância adotado de 5%. Resultados Amostra (n = 35) apresentou idade média de 52,5 ± 8,1 anos e PCR Chagas positiva em 22 pacientes (62,8%). As médias dos menores valores de linfócitos nos primeiros 14 dias do TxC foram 398 ± 189 e 755 ± 303 células/mm3 em pacientes com e sem parasitemia nos 3 meses após o TxC, respectivamente (área sob a curva = 0,857; intervalo de confiança de 95%: 0,996 a 0,718, sensibilidade e especificidade de 83,3% e 86,4%). Determinado valor de corte inferior a 550 linfócitos/mm3 como fator de risco para presença de parasitemia. Pacientes com linfócitos < 550 unidades/mm3 nos primeiros 14 dias do pós-TxC apresentaram PCR positiva em 80% dos casos. Para cada aumento de 100 linfócitos/mm3, o risco de positividade da PCR é reduzido em 26% (razão de riscos = 0,74; intervalo de confiança de 95%: 0,59 a 0,93, p = 0,009). Conclusão Houve associação entre a linfopenia no perioperatório do TxC com a parasitemia precoce pelo T. cruzi detectada por PCR.

Abstract Background It is unknown whether lymphopenia is a risk factor for the reactivation of Chagas disease in heart transplantation (HTx), as recently described in the reactivation of cytomegalovirus in transplant patients. Objective To evaluate whether lymphopenia in the perioperative period of heart transplantation is related to early Trypanosoma cruzi parasitemia. Methods This observational, retrospective study analyzed a sample from January 2014 to January 2023). Parasitemia was evaluated in the first 3 months after HTx using serum polymerase chain reaction (PCR) and compared with the total lymphocyte count in the perioperative period of HTx using receiver operating characteristic curves. Baseline characteristics were compared with PCR for Chagas using independent Cox proportional hazards models. A significance level of 5% was adopted. Results The sample (n = 35) had a mean age of 52.5 ± 8.1 years, and 22 patients (62.8%) had positive PCR for Chagas. The mean lowest lymphocyte values in the first 14 days after HTx were 398 ± 189 and 755 ± 303 cells/mm3 in patients with and without parasitemia, respectively, within 3 months after HTx (area under the curve = 0.857; 95% confidence interval: 0.996 to 0.718, sensitivity and specificity of 83.3% and 86.4%). A cutoff value of less than 550 lymphocytes/mm3 was determined as a risk factor for the presence of parasitemia. Patients with lymphocytes < 550 units/mm3 in the first 14 days after HTx presented positive PCR in 80% of cases. For every increase of 100 lymphocytes/mm3, the risk of PCR positivity was reduced by 26% (hazard rate ratio = 0.74; 95% confidence interval: 0.59 to 0.93, p = 0.009). Conclusion There was an association between lymphopenia in the perioperative period of HTx and early T. cruzi parasitemia detected by PCR.

Cutting-edge issues in sympathetic ophthalmia approach and six case reports: a T cell-mediated autoimmune response / As questões de ponta na abordagem da oftalmia simpática e 6 relatos de caso: uma resposta autoimune mediada por células T

ABSTRACT Sympathetic ophthalmia is a rare and potentially devastating bilateral diffuse granulomatous panuveitis. It is caused by surgical or non-surgical eye injuries and is an uncommon and serious complication of trauma. It is diagnosed clinically and supported by imaging examinations such as ocular ultrasonography and optical coherence tomography. Its treatment consists of immunosuppressive therapy with steroids and sometimes steroid-sparing drugs, such as cyclosporine, azathioprine, cyclophosphamide, and mycophenolate mofetil. Fast and effective management with systemic immunosuppressive agents allows for disease control and achievement of good visual acuity in the sympathizing eye. By contrast, enucleation should be considered only in situations where the injured eye has no light perception or in the presence of severe trauma. In addition to a bibliographic review of this topic, we report six cases involving different immunosuppressive and surgical treatment modalities.

RESUMO A oftalmia simpática consiste em uma panuveíte granulomatosa bilateral rara e potencialmente devastadora, ocorrendo geralmente após trauma ocular cirúrgico ou não cirúrgico. O diagnóstico é baseado em aspectos clínicos e apoiado por exames de imagem, como ultrassonografia ocular e tomografia de coerência óptica. O tratamento consiste em terapia imunossupressora com esteróides e, eventualmente, drogas poupadoras de esteróides, como ciclosporina, azatioprina, ciclofosfamida e micofonato de mofetila. O manejo rápido e eficaz com agentes imunossupressores sistêmicos permite o controle da doença e a obtenção de boa acuidade visual no olho simpatizante. A enucleação, por outro lado, poderia ser considerada apenas em situações em que o olho lesado não tem percepção luminosa ou há trauma grave. Além de uma revisão bibliográfica sobre o tema, foi relatada uma série de 6 casos com diferentes modalidades de tratamento imunossupressor e cirúrgico.

Autochtonal case of chronic, unifocal, pulmonary paracoccidioidomycosis with methotrexate use, in Salvador ‒ Brazil

Abstract Summary We report an autochthonous case of mild unifocal chronic pulmonary paracoccidioidomycosis in a 48-year-old previously healthy woman with no history of possible environmental exposures in endemic rural areas, supposedly resulting from reactivation of a latent pulmonary focus secondary to the use of methotrexate for the control of Chikungunya arthropathy. Laboratory investigation ruled out other immunosuppression. Her only symptoms were a dry cough and chest pain. Diagnosis confirmed by needle lung biopsy. There were no abnormalities on physical examination nor evidence of central nervous system involvement. MRI of the total abdomen showed no involvement of other organs. Computed chest tomography showed a favorable evolution under the use of itraconazole (200 mg/day). Different tomographic presentations findings are highlighted when performed before and after treatment. Conclusions PCM should be considered even in a woman without a history of consistent environmental exposure and in a non-endemic geographic area.
