ABSTRACT

Al editor: Clásicamente se ha considerado la amiloidosis cardiaca como una afección rara, con un amplio espectro de síntomas que requiere un alto índice de sospecha. Sin embargo, los estudios han demostrado que la amiloidosis cardiaca por transtiretina (TTR) es más común de lo que previamente se creía1,2. Las características clínicas que se han asociado a la amiloidosis cardiaca por TTR son el sexo masculino, la edad avanzada, la hipertrofia concéntrica y la función ventricular izquierda preservada1. Se realizó un análisis descriptivo retrospectivo de las gammagrafías solicitadas en nuestro centro para descartar amiloidosis cardiaca por TTR desde septiembre de 2016 hasta noviembre de 2019. En dicho periodo se realizaron 39 gammagrafías, con una tendencia al alza en los últimos meses. Los objetivos fueron evaluar las gammagrafías solicitadas y conocer el porcentaje de gammagrafías diagnósticas de amiloidosis por TTR, establecer qué características son más frecuentes en los pacientes con amiloidosis por TTR en nuestra población de referencia y analizar las características diferenciales de las distintas posibilidades diagnósticas. Del total de las pruebas, 22 (56.4% de la muestra) mostraron una captación de grado 2-3 de Perugini, diagnóstica de amiloidosis por TTR. De acuerdo con las recomendaciones de diagnóstico no invasivo de amiloidosis cardiaca por TTR3, se descartó la presencia de pico monoclonal. Únicamente se realizó estudio genético a 10 pacientes, en dos de los cuales se detectó una mutación patogénica (Val50Met y variante patogénica c.290C>A en heterocigosis); los ocho restantes no mostraron mutaciones en el estudio molecular del gen TTR.

ABSTRACT

RESUMEN La amiloidosis laríngea es un desorden infrecuente con síntomas inespecíficos que dificultan su diagnóstico. A través de la descripción y análisis de tres casos valorados en el Hospital Universitario San Ignacio, Bogotá buscamos ampliar el conocimiento en esta patología y comparar nuestros hallazgos con los descritos en la literatura. Se realizó una búsqueda retrospectiva de pacientes con diagnóstico de amiloidosis laríngea en los últimos cinco años en nuestra institución, obteniendo un total de 3 pacientes que cumplieron con nuestros criterios de selección. El síntoma más frecuente en estos pacientes fue la disfonía. La principal presentación encontrada fue de tipo sistémica, contrario a lo reportado en la literatura. Se realizó una remodelación de la vía aérea mediante microcirugía laríngea con láser de dióxido de carbono, obteniendo resultados clínicos satisfactorios. Es importante realizar más estudios del tema en nuestro país, teniendo en consideración el número reducido de casos debido a su baja prevalencia.


SUMMARY Laryngeal amyloidosis in an infrequent disorder, with nonspecific symptoms that difficult the diagnosis and without a consensus for its treatment. Through the description, analysis and comparison of three cases of laryngeal amyloidosis at the Hospital Universitario San Ignacio Bogotá, we seek to expand the knowledge in this pathology and compare it with what is described in the literature. We made a retrospective research of patients with a diagnosis of laryngeal amyloidosis in the last five years in our institution, obtaining a final sample of 3 cases that met the inclusion criteria. The most frequent symptom was dysphonia, the most frequent presentation was systemic, contrary to what was reported in the literature. Airway remodeling was performed using laryngeal microsurgery with carbon dioxide laser, obtaining good clinical results. We con-sider important to carry out more studies on the subject in our country.

ABSTRACT

OBJECTIVE@#To summarize and compare the clinical baseline characteristics of patients with monoclonal gammopathy of undetermined significance (MGUS), primary light chain amyloidosis (pAL), multiple myeloma (MM), or MM with concurrent amyloidosis, especially the differences in cytogenetic abnormalities.@*METHODS@#The clinical data of 15 cases of MGUS, 34 cases of pAL, 842 cases of MM and 23 cases of MM with concurrent amyloidosis were analyzed and compared retrospectively.@*RESULTS@#Cytogenetic statistics showed that the incidence of t (11; 14) in the four groups (MGUS vs pAL vs MM vs MM with concurrent amyloidosis) was 0%, 33.3%, 16.4%, and 15.8%, respectively (P=0.037); that of 13q deletion was 20.0%, 14.7%, 45.8% and 56.5%, respectively (P<0.001); gain of 1q21 was 50.0%, 12.5%, 47.4% and 40.9%, respectively (P=0.001). Proportion of pAL patients with 0, 1 and≥2 cytogenetic abnormalities (including 13q deletion, 17p deletion, 1q21 amplification and IgH translocation) accounted for 41.9%, 41.9% and 16.1%, respectively; while the proportion of the same category in MM was 17.6%, 27.3%, and 55.2% respectively; this ratio of MM with concurrent amyloidosis was more similar to MM. Subgroup analysis showed that genetic abnormalities (including 13q deletion, 17p deletion and 1q21 amplification) were comparable within t (11; 14) negative and positive groups. Compared with positive cases, t(11; 14) negative patients with MM or MGUS were more likely to have 13q deletions and multiple genetic abnormalities.@*CONCLUSION@#Clinical characteristics of pAL, especially cytogenetic abnormalities, are significantly different from MM with concurrent amyloidosis. It suggests that although the onset characteristics are similar, actually the two diseases belong to different disease subtypes which should be carefully predicted and identified.

ABSTRACT

A amiloidose é uma condição rara que descreve um grupo heterogêneo de distúrbios que cursam com a deposição extracelular de agregados proteicos fibrilares em tecidos e órgãos. Relata-se aqui o caso de paciente do sexo masculino, com 76 anos de idade, que, há 2 meses, iniciou quadro progressivo de dispneia aos mínimos esforços. Na investigação, observou-se aumento cardíaco global, e o ecocardiograma evidenciou cardiopatia restritiva infiltrativa e derrame pericárdico. Pela elevada suspeição clínica, foi solicitada ressonância magnética cardíaca, que foi altamente sugestiva de amiloidose cardíaca. Dessa forma, assim como no caso relatado, o acometimento cardíaco possui como principal forma de manifestação o tipo miocardiopatia restritivo, sendo um quadro de insuficiência cardíaca crônica com etiologia de difícil diagnóstico em pacientes acima de 50 anos, com prognóstico bastante reservado. Assim, apesar de permanecer como um desafio diagnóstico para o clínico, sua hipótese deve sempre ser aventada na ausência de outra causa que justifique tais achados (AU)

ABSTRACT

First described by Rokitansky in 1842, and further characterized by Virchow in 1854, amyloidosis is a disorder caused by amyloid deposition, a fibrillary insoluble protein. The clinical spectrum of amyloidosis is broad, as the amyloid deposition may virtually occur in all tissues. Herein, we report the case of a 66-year-old man with a long-lasting emaciating disease, diagnosed, at autopsy, with primary systemic amyloidosis. Amyloid protein deposition was found in many tissues and organs. The involvement of the vessels' wall rendered ischemic injury most prominent in the intestinal loops causing mesenteric ischemia. Despite the thorough organic involvement, the immediate cause of death was aspiration bronchopneumonia. Massive amyloid deposition was found in virtually all major organs, such as the heart, liver, kidneys, spleen, pancreas, adrenals, prostate, skin, and thyroid: the latter, a complication of the amyloidosis known as amyloid goiter. Post-mortem review of the deceased's laboratory workup showed a slightly abnormal kappa:lambda ratio in the blood; however, no clonal lymphoplasmacytic disorder was confirmed in the bone marrow and other lymphoreticular system organs either by the microscopic examination and immunohistochemical staining. Laser-capture microdissection and tandem mass spectrometry of the splenic tissue detected a peptide profile consistent with an immunoglobulin Kappa light chain. The presence of amyloid purpura favors the diagnosis of primary systemic amyloidosis.

ABSTRACT

Presentamos el caso de un paciente de 56 años con antecedente de Mieloma Múltiple, que evoluciona con inflamación periorbitaria de ambos parpados, bilateral, de coloración amarillenta-violácea, ulcerada e indolora. Se planteó el diagnóstico diferencial con las enfermedades xantogranulomatosas orbitarias del adulto, en especial con su asociación con Mieloma Múltiple (MM). Al realizar biopsia de la lesión, se observan en la histología fragmentación de haces de colágeno dérmico y alrededor de vasos un material amorfo acelular eosinófilo pálido, rojo congo positivo y coloración verde manzana con luz polarizada, llegando al diagnóstico de Amiloidosis y Xantogranuloma Orbitario del Adulto.


We present the case of a 56-year-old patient with a history of Multiple Myeloma, who evolves with periorbital inflammation of both eyelids, bilateral, yellowish-violet, ulcerated and painless. The differential diagnosis with the adult orbital xanthogranulomatous diseases was raised, especially XN due to its association with MM. When performing a biopsy of the lesion, fragmentation of dermal collagen bundles and around vessels a pale eosinophilic acellular material, positive congo red and apple-green color with polarized light are observed in the histology, reaching the diagnosis of Amyloidosis and Orbital Xantogranuloma of the Adult.

ABSTRACT

Resumo Evidências recentes sugerem que a amiloidose cardíaca é uma doença amplamente subdiagnosticada, particularmente na sua forma ligada à transtirretina, podendo ser uma causa comum de insuficiência cardíaca com fração de ejeção preservada (ICFEP) no idoso. Os novos paradigmas sobre a doença incluem o desenvolvimento de novas terapias específicas que modificam a história natural da doença. Este artigo traz uma síntese destes novos conceitos.


Abstract Recent evidence suggests cardiac amyloidosis (CA) is a mostly underdiagnosed condition, particularly in the transthyretin-mediated form, and is a frequent cause of heart failure with preserved ejection fraction (HFpEF) in the elderly. New paradigms about CA also involve the development of disease-modifying specific therapies. This article summarizes these new concepts.

Objetivo: Describir un caso de amiloidosis cardiaca asociada a macroglobulinemia. Caso clínico: Paciente masculino que fue admitido por astenia, disfonía, y durante su evolución desarrolló disnea progresiva, insuficiencia cardiaca y efusión pleural. Adicionalmente, la ecocardiografía mostró patrón granular miocárdico, y la biopsia pleural resultó positiva para la tinción rojo congo. Posteriormente, recibió tratamiento con bortezomib, dexametasona y rituximab con evolución favorable. Conclusiones: En esta enfermedad el diagnóstico temprano es una ventaja importante para la supervivencia. Es por esa razón, que su manejo es paliativo de las manifestaciones cardiacas. El presente caso pone en manifiesto un reto diagnóstico, en el cual se deben tomar en cuenta las etiologías menos frecuentes de insuficiencia cardiaca(AU)


Introduction: Waldenström's macroglobulinemia is a hematological neoplasm belonging to the group of monoclonal gammopathies, which includes systemic symptoms and those related to an increase in M paraprotein. Objective: To describe a case of cardiac amyloidosis associated with macroglobulinemia. Clinical case: Male patient who was admitted for asthenia, dysphonia, and who, during his evolution, developed progressive dyspnea, heart failure and pleural effusion. Additionally, echocardiography showed myocardial granular pattern, while pleural biopsy was positive for Congo red staining. Subsequently, he received treatment with bortezomib, dexamethasone and rituximab, with favorable evolution. Conclusions: In this disease, early diagnosis is an important advantage for survival. Therefore, its management is palliative of cardiac manifestations. The present case shows a diagnostic challenge, in which the less frequent etiologies of heart failure must be taken into account(AU)

ABSTRACT

SUMMARY Cardiac amyloidosis is an infiltrative disease which requires a high degree of clinical suspicion for appropriate diagnosis. Early diagnosis and the definition of the type of amyloidosis play a key role in the early treatment and prognosis of this disease. In this context, the use of cardiac biomarkers such as troponins and NT-proBNT associated with analysis by multimodality imaging methods like echocardiographic techniques such as strain, nuclear medicine, and cardiovascular resonance imaging have an increasing role in patients with cardiac amyloidosis. This article details the role of non-invasive diagnostic methods in patients with cardiac amyloidosis.


RESUMO A amiloidose cardíaca é uma doença infiltrativa que exige um alto grau de suspeição clínica para o diagnóstico apropriado. O diagnóstico precoce e a definição do subtipo de amiloidose têm um papel fundamental para a terapêutica e prognóstico desta doença. Nesse contexto, o emprego de biomarcadores cardíacos como as troponinas e NT-proBNT associados à análise por métodos de imagem multimodalidade por técnicas ecocardiográficas atuais como o strain, medicina nuclear e a ressonância magnética cardíaca têm papel crescente em pacientes com amiloidose. Este artigo detalha a utilização dos métodos não invasivos para a avaliação de pacientes com amiloidose cardíaca.

ABSTRACT

We describe an autopsy case of a 45-year-old male diagnosed with autosomal dominant polycystic kidney disease who presented with complaints of altered sensorium. The autopsy revealed multiple tumor-like masses in the liver, which on histological examination depicted multiple large suppurative granulomas with the presence of variable acid-fast coccobacilli (consistent with Brucella spp.). Interestingly, extensive amyloid deposition in multiple organs was noted. To the best of our knowledge, this is the first case of chronic brucellosis causing tumor-like abscesses in the liver accompanied by secondary systemic amyloidosis in a patient with underlying autosomal dominant polycystic kidney disease.

ABSTRACT

El diagnóstico diferencial de la macroglosia es amplio y puede estar en el contexto de una patología localizada o una enfermedad sistémica. Dentro de las enfermedades sistémicas que se manifiestan con macroglosia se describe la amiloidosis, caracterizada por un depósito irreversible de una proteína amorfa y fibrilar El compromiso de esta patología en el territorio de cabeza y cuello es infrecuente y su depósito en la lengua corresponde a menos del 9% de los casos. Se presenta el caso de un paciente que consultó por dolor en hemilengua derecha, disfagia y baja de peso. Se estudió inicialmente con exámenes de laboratorio y nasofibroscopía, sin hallazgos concluyentes. Dado persistencia de síntomas se realizó resonancia nuclear magnética (RM) que mostraba signos sugerentes de enfermedad de depósito, confirmándose mediante estudios histopatológicos una amiloidosis sistémica secundaria. El paciente fue derivado a hematología para completar estudio e iniciar el tratamiento. La amiloidosis sistémica es un diagnóstico infrecuente, que debe ser considerado por su mal pronóstico vital. El diagnóstico en etapas iniciales puede mejorar sustancialmente la sobrevida y calidad de vida de aquellos que padecen la enfermedad. Por lo anterior, es necesario completar un estudio acabado de la patología, apoyándose en métodos no invasivos como la RM.


The differential diagnosis of macroglossia is broad, and it may be present in the context of a localized pathology or a systemic disease. One of the systemic diseases that present macroglossia is amyloidosis, which is characterized by an irreversible deposit of an amorphous and fibrillar protein. The manifestation of this pathology in head and neck territory is infrequent, and its deposit in the tongue represents less than 9% of all types of amyloidosis. We present the case of a patient, who consulted with pain in the tongue, dysphagia, and weight loss. He was initially studied with laboratory tests and a nasofibroscopy with no conclusive findings. Given the persistence of symptoms, magnetic resonance imaging (MRI) was performed, showing signs of an infiltrative disease, which was confirmed as secondary systemic amyloidosis through histopathological studies. Given the above, the patient was referred to hematology to start treatment. Systemic amyloidosis is an uncommon diagnosis that should be suspected since it implies a poor vital prognosis. Moreover, an early diagnosis can substantially improve the survival rate and quality of life of those who suffer this disease. Therefore, a comprehensive study of this condition is needed, complementing with non-invasive methods such as MRI.

ABSTRACT

Amyloidosis comprises a group of disorders that accumulate modified autologous proteins in organs, mainly the kidneys. Few studies have addressed the amyloid compartmental distribution and associated clinical outcomes. The aim of this study was to present a case series of renal amyloidosis correlating histopathological data with glomerular filtration rate (GFR) during kidney biopsy. We studied 53 cases reviewed by nephropathologists from 2000 to 2018 in a single kidney biopsy center in Brazil. GFR was estimated using the CKD-EPI formula. Cases were divided into Group A ≥60 and Group B <60 mL·min−1·(1.73 m2)−1 using the estimated GFR during kidney biopsy. Semiquantitative histopathological study was performed, including extension and distribution of amyloid deposits by compartments (glomeruli, tubulointerstitial tissue, and vessels). Statistical analyses were made to understand associations with lower GFR. No difference was seen for age, gender, proteinuria, hematuria, subtype of amyloid protein, arteriosclerosis, interstitial fibrosis/infiltrate, or glomerular and interstitial amyloid deposits. After a previous P value <0.1 in the descriptive analysis, the following variables were selected: globally sclerotic glomeruli, high blood pressure, and the extension of vascular amyloid deposition. A binary logistic regression model with GFR as the dependent variable showed history of hypertension and vascular amyloid to be robust and independent predictors of Group B <60 mL·min−1·(1.73 m2)−1. Beyond the histopathologic diagnosis of amyloidosis, a semiquantitative approach on renal biopsy could provide new insights. Vascular amyloid is an independent predictor of renal dysfunction in cases of renal amyloidosis.

ABSTRACT

Abstract İntroduction: Familial Mediterranean fever (FMF) is a hereditary auto-inflammatory disease characterized by recurrent fever and serosal inflammation. Anti-interleukin-1 (Anti-IL-1) treatments are recommended in colchicine resistant and/or intolerant FMF patients. This study aims to evaluate the efficacy of anakinra and canakinumab in FMF patients that are resistant/intolareted to colchicine or complicated with amyloidosis. Methods: Between January 2014 and March 2019, 65 patients following-up at Sivas Cumhuriyet University (Medical Faculty Rheumatology-Internal Medicine Department) who were diagnosed with FMF according to the criteria of Tel-Hashomer were included in the study. The laboratory values and clinical features of patients and disease activities were recorded at least every 3 months, and these data were analyzed. Results: Forty-one (63.1%) patients used anakinra (100 mg/day) and 24 (36.9%) patients used canakinumab (150 mg/8 week). The median duration of anti-IL-1 agents use was 7 months (range, 3-30). Fifteen (23.1%) cases were complicated with amyloidosis. Seven (10.8%) patients had renal transplantation. Overall, the FMF 50 score response was 96.9%. In the group that had a glomerular filtration rate (GFR) ≥ 60 ml/min/m2, the median proteinuria decreased from 2390 mg/day (range, 1400-7200) to 890 mg/day (range, 120-2750) (p = 0.008). No serious infections were detected, except in one patient. Conclusions: Anti-IL-1 agents are effective and safe in the treatment of FMF patients. These agents are particularly effective at reducing proteinuria in patients with GFR ≥ 60 ml/min/m2, but less effective in cases with FMF associated with arthritis and sacroiliitis. Large and long follow-up studies are now needed to establish the long-term effects of these treatments.

ABSTRACT

ABSTRACT Renal manifestations of spondyloarthritis are rare. The case is presented of a patient with ankylosing spondylitis of nine years of evolution. He had intense inflammation, as well as articular sequelae, with a significant deterioration in his quality of life. At the initial evaluation, the patient had a serum creatinine of 1.44mg/dL and a 24-h urine protein in the sub-nephrotic range (1.44 g). Renal biopsy showed the presence of Congophilic material, confirming the diagnosis of AA amyloidosis. Treatment with a TNF blocking agent was initiated with clinical improvement, especially regarding articular disease.


RESUMEN Las manifestaciones renales de la espondiloartritis son poco comunes. Se presenta el caso de un paciente con espondilitis anquilosante de 9 anos de evolución, con intensa inflamación y secuelas articulares y con un deterioro significativo en su calidad de vida. En la evaluación inicial, el paciente tenía una creatinina sérica de 1,44mg/dL y una proteína en orina de 24 horas en un rango subnefrótico (1,44 g). La biopsia renal mostró la presencia de material congofílico que confirmaba el diagnóstico de amiloidosis AA. Se inició tratamiento con un anti-TNF, con mejoría clínica, especialmente con respecto al componente articular.
