RESUMO
Resumen Introducción: la bacteriemia en pacientes cirróticos es frecuente y se asocia con una alta mortalidad y hospitalización prolongada. Este estudio describe las características demográficas, clínicas y de laboratorio en pacientes con cirrosis hepática y bacteriemia en un hospital de cuarto nivel. Métodos: estudio observacional de cohorte retrospectiva. Incluyó pacientes con cirrosis hepática y bacteriemia entre el 1 de enero de 2010 y el 31 de diciembre de 2017 en el Hospital Pablo Tobón Uribe de Medellín, Colombia. Se recogieron variables demográficas, clínicas y de laboratorio. Se estimó la supervivencia durante el tiempo de hospitalización y hasta 30 días desde el diagnóstico de bacteriemia. Resultados: se hallaron 78 pacientes con cirrosis y bacteriemia. La media de edad fue de 65 años, 66,7 % fueron mujeres. Las principales etiologías de la cirrosis fueron: criptogénica (30,8 %) y esteatohepatitis no alcohólica (EHNA; 19,3 %). La principal fuente de infección fue la vía urinaria (24 %), seguida de colangitis (23 %) y la bacteriemia espontánea (19 %). Los bacilos gramnegativos (BGN) representaron la mayoría de los aislamientos (67,9 %). La prevalencia de multidrogorresistentes (MDR) fue de 25,6 % y el uso adecuado de antibiótico empírico fue de 80,8 %. La mortalidad a 30 días fue de 11,5 %. Como mejores predictores de mortalidad se encontraron la puntuación Child-Pugh y Model for End-stage Liver Disease (MELD) al ingreso con área bajo la curva ROC (AUROC) de 0,79 (p = 0,008) y 0.72 (p = 0,042), respectivamente. Conclusiones: los hallazgos permiten conocer las principales características de los pacientes con cirrosis que desarrollan bacteriemia en nuestro medio. Se encontró un número considerable de infecciones MDR. Los pacientes con un grado avanzado de la cirrosis son los que presentan un mayor riesgo de mortalidad.
Abstract Introduction: Bacteremia in cirrhotic patients is frequent and associated with high mortality and prolonged hospital stays. This study describes the demographic, clinical, and laboratory characteristics of patients with liver cirrhosis and bacteremia treated at a quaternary care hospital. Methodology: Observational, retrospective cohort study. The sample consisted of patients with liver cirrhosis and bacteremia treated between January 1, 2010, and December 31, 2017, at the Hospital Pablo Tobon Uribe of Medellín, Colombia. Demographic, clinical, and laboratory variables were collected. Survival was estimated during the time of hospitalization and up to 30 days following the diagnosis of bacteremia. Results: 78 patients had cirrhosis and bacteremia. The average age was 65 years; 66.7% were women. Cirrhosis was labeled cryptogenic in 30.8% of the cases and NASH in 19.3%. The main source of infection was the urinary tract (24%), followed by cholangitis (23%) and spontaneous bacteremia (19%). Gram-negative bacteria were observed in most of the isolates (67.9%). The prevalence of MDR was 25.6%, and the adequate use of empirical antibiotics was 80.8%. The 30-day mortality rate was 11.5%. The best mortality predictors were the Child-Pugh and MELD scores on admission with AUROC of 0.79 (P=0.008) and 0.72 (P=0.042), respectively. Conclusions: The findings allow describing the main characteristics of patients with cirrhosis who develop bacteremia in our environment. A considerable number of MDR infections were found. Patients with an advanced degree of cirrhosis are at the highest risk of mortality.

Cryptococcosis is an opportunistic infection caused by the Basidiomycota Cryptococcus neoformans (Cryptococcus gattii), which affects immunosuppressed patients and less frequently immunocompetent patients. Solid-organ transplant recipients are a particularly high-risk group, depending on the net state of immunosuppression. In these patients, the infection usually appears after the first year after transplant, although it may occur earlier in liver transplant recipients. In most cases, the infection is secondary to the reactivation of a latent infection, although it may be due to an unidentified pretransplant infection by primary infection. Less frequently, it may be transmitted by the graft. The lung and central nervous system are most frequently involved. Extrapulmonary involvement is seen in 75% of the cases, and disseminated disease occurs in 61%, with mortality ranging from 17% to 50% when the central nervous system is involved. Here, we report a case of disseminated cryptococcosis (lymphadenitis, meningitis, pulmonary nodules, and possibly sacroiliitis) in a patient after liver transplant, with good clinical and microbiological outcomes and without relapse.

Resumen Introducción: en la hepatitis autoinmune (HAI), los ancianos representan una población especial debido a que, según se ha descrito, poseen una predisposición mediada por el antígeno leucocitario humano (Human Leukocyte Antigen, HLA) y padecen un curso indolente y progresivo de la enfermedad. No se conocen datos en la población latinoamericana. Objetivos: Analizar comparativamente las características de los pacientes con HAI mayores y menores de 65 años en cuanto a su presentación clínica, diagnóstico, tratamiento, respuesta al tratamiento y curso de la enfermedad. Métodos: estudio de cohorte retrospectiva de pacientes con HAI evaluados entre enero de 2010 y diciembre de 2016. Se realizó un análisis estadístico utilizando el programa SPSS versión 20.1. Resultados: se incluyeron 214 pacientes. Los pacientes ancianos tuvieron, en su mayoría, hipertensión arterial (34,5 % frente a 15,1 %, p = 0,011), dislipidemia (20,7 % frente a 5,9 %, p = 0,006) y enfermedad cardiovascular (17,2 % frente a 2,7 %, p = 0,001). Además, al momento del diagnóstico, los pacientes ancianos tuvieron una mayor frecuencia de cirrosis evaluada histológica y radiológicamente (55,1 % frente a 33,5 %, p = 0,024). Los pacientes mayores tuvieron una mayor remisión bioquímica con el tratamiento (100 % frente a 83,9 %, p = 0,022). No hubo diferencias en la analítica hepática, autoanticuerpos, tipo de tratamiento farmacológico recibido, recaídas, efectos adversos relacionados con el tratamiento, requerimiento de trasplante hepático y muerte. Conclusión: La HAI afecta a población colombiana adulta de todas las edades y debe ser considerada en el abordaje diagnóstico de los ancianos con enfermedad hepática, debido a que este grupo de pacientes tiene una mayor frecuencia de cirrosis al momento del diagnóstico. Un diagnóstico temprano es importante debido a que el tratamiento es efectivo y bien tolerado.
Abstract Introduction: Elderly patients with autoimmune hepatitis (AIH) are a special population because of predisposition mediated by the human leukocyte antigen (HLA) system. An indolent and progressive course of the disease has been described. No data are known for the Latin American population. Objectives: This study compares clinical presentations, diagnoses, treatments, responses to treatment and course of disease for AIH patients who are over 65 years of age with those of AIH patients who are under 65. Methods: This is a retrospective cohort study of patients with HAI evaluated between January 2010 and December 2016. Statistical analyses used SPSS version 20.1. Results: Two hundred fourteen patients were included. Elderly patients had hypertension (34.5% vs 15.1%, p = 0.011), dyslipidemia (20.7% vs 5.9%, p = 0.006) and cardiovascular disease (17.2% vs 2.7%, p = 0.001) more frequently than did the younger patients. In addition, the elderly had a higher frequency of cirrhosis confirmed histologically and radiologically (55.1% vs. 33.5%, p = 0.024) at the time of diagnosis. Older patients had a higher rate of biochemical remission resulting from treatment (100% vs 83.9%, p = 0.022). There were no differences in hepatic analyses, autoantibodies, type of pharmacological treatment received, relapses, adverse effects related to treatment, requirements for liver transplantation and deaths. Conclusion: AIH affects the Colombian adult population at all ages and should be considered in the diagnostic approach of elderly patients who have liver disease because this group has a higher frequency of cirrhosis at the time of diagnosis. Early diagnosis is important because treatment is effective and well tolerated.

BACKGROUND AND AIM: Drug-induced autoimmune hepatitis (DIAIH) is an adverse effect associated with several drugs that usually occurs acutely, with variable latency, and it may potentially be mortal. There are a few reports and studies about DIAIH. METHODS: This was an analytical study of a retrospective cohort of patients, discriminated according to idiopathic or drug-induced etiology, followed up for a 7-year period until 31 December 2016. RESULTS: A total of 190 patients were selected for the analysis, 12 (6.3%) with DIAIH. The two main drugs related to DIAIH were nitrofurantoin, n = 8 (67%), and NSAID, n = 2 (17%), constituting 84% of the cases. There were no significant differences in seropositivity between AIH with DIAIH in antinuclear antibodies (ANA) and anti-smooth muscle antibodies (ASMA) antibodies, with 82.6% versus 82.6% and 34% versus 16%, respectively. The fibrosis stages were similar, except for the F4 stage, in a greater proportion in AIH. None of the patients with DIAIH had cirrhosis or developed it during follow-up, but it was present in 42.1% of the AIH cases at diagnosis (P = 0.003). Biochemical remission with management was higher in DIAIH but not significant (91.7% vs 80.9%, P = 0.35). The definitive interruption of immunosuppression was successfully performed in 25% of those with DIAIH without relapses but was only possible in 2.8% in AIH (P < 0.001) with 32 cases of relapses. CONCLUSION: DIAIH constitutes a minor proportion of AIH. The clinical and histological characteristics may be similar; DIAIH patients have a greater chance of having treatment suspended with a low risk of relapse, progression to cirrhosis, or need for liver transplant.
RESUMO
Resumen Introducción: la recurrencia de hepatitis autoinmune (HAI) postrasplante implica riesgo de cirrosis y pérdida del injerto. Se han propuesto factores de riesgo para su recurrencia, de los cuales pocos datos se conocen en pacientes latinoamericanos. Objetivos: describir las características de los pacientes con trasplante hepático por HAI y evaluar aquellas asociadas con su recurrencia durante el postrasplante. Métodos: cohorte histórica, incluyó pacientes con HAI diagnosticada a partir de los 16 años y que fueron llevados a trasplante hepático en un hospital universitario de Medellín, Colombia, entre enero de 2010 y septiembre de 2017. La recolección de la información se realizó a partir de los registros de historia clínica. Resultados: se incluyeron 25 pacientes. Se diagnosticó recurrencia en el 24%. La mediana de seguimiento fue de 59,5 meses y de recurrencia 32,5 meses (rango 11-123 meses). El 100% del grupo de recurrencia era de sexo femenino y ninguna de estas se trasplantó por insuficiencia hepática aguda. No hubo diferencias en las características pretrasplante y de tratamiento, aunque se encontró una mayor actividad inflamatoria bioquímica e histológica pretrasplante en el grupo de recurrencia. Del grupo con recurrencia, el 100% recibió glucocorticoides a largo plazo y el 33,3% tuvo pérdida del injerto relacionada con la recurrencia, por lo que requirieron retrasplante (p = 0,008). Conclusión: La recurrencia de HAI postrasplante hepático en nuestros pacientes es similar a la reportada mundialmente, es una causa de disfunción del injerto para tener en cuenta especialmente después del primer año postrasplante, predomina en mujeres. El 33,3% de los pacientes requiere retrasplante hepático por disfunción del injerto.
Abstract Introduction: The recurrence of post-transplant autoimmune hepatitis implies risk of cirrhosis and graft loss. Risk factors have been proposed for recurrence, of which few data are known in Latin American patients. Objectives: To describe the characteristics of patients with liver transplantation for autoimmune hepatitis and to evaluate those associated with their recurrence during post-transplant. Methods: Historical cohort included patients with autoimmune hepatitis diagnosed after the age of 16 years and who were taken to liver transplant in a university hospital in Medellin, Colombia between January 2010 and September 2017. Collection of information from the registers of clinical history. Results: 25 patients were included. Recurrence was diagnosed in 24%. Median follow-up was 59.5 months and recurrence 32.5 months (range 11-123 months). 100% of the recurrence group were women and none of these were transplanted due to acute liver failure. There were no differences in the pre-transplant and treatment characteristics, although a higher biochemical and histological inflammatory activity was found pre-transplant in the recurrence group. Of the group with recurrence, 100% received long-term glucocorticoids and 33.3% had graft loss related to recurrence requiring retransplantation (p = 0.008). Conclusion: The recurrence of autoimmune hepatitis after liver transplantation in our patients is similar to that reported worldwide, is a cause of graft dysfunction to be taken into account especially after the first year post-transplant, it predominates in women. 33.3% of patients require hepatic retransplantation due to graft dysfunction.

BACKGROUND: Autoimmune hepatitis (AIH) with characteristics of primary biliary cholangitis (PBC) is known as overlap syndrome. Its prevalence and prognosis have not yet been determined comparatively with AIH. METHODS: A retrospective cohort study was conducted comparing patients diagnosed with AIH and AIH-PBC overlap syndrome, followed-up for seven years in a university hospital in Colombia, until 31 December 2016. RESULTS: A total of 210 patients were included (195 women, mean age 48.5years). Of these, 32 (15.2%) had AIH-PBC overlap syndrome. At diagnosis, no significant differences were found by demographic profile, positive autoantibodies (ANA, ASMA), except AMA (81.2% vs 3.9%, P<.001), and histological grade of fibrosis. The most frequent clinical presentations were nonspecific symptoms in AIH-PBC and acute hepatitis in AIH. Although there were no significant differences, AIH showed a greater biochemical response to immunosuppressive management (87.3% vs 74.2%, P=.061) and a greater number of relapses in those who achieved partial or complete remission during treatment (12.4% vs 7.63%; P=.727). Patients with AIH-PBC had greater progression to cirrhosis (22.2% vs 13.1%, P=.038), even in those who achieved partial or complete biochemical remission without relapse, with greater indication of orthotopic liver transplantation (P=.009), but not retransplantation (P=.183); there were no differences in mortality. CONCLUSIONS: AIH-PBC overlap syndrome accounts for a significant proportion of patients with AIH, with greater progression to cirrhosis, indication of liver transplantation and possibly retransplantation. This higher risk of adverse outcomes suggests closer monitoring, probably with follow-up until confirmed histopathological remission.
