Malformación linfática quística gigante del hígado: dos casos pediátricos con diferente abordaje quirúrgico / Giant cystic lymphatic malformation of the liver: two pediatric cases with different surgical approach

Introducción. Las malformaciones linfáticas quísticas, también llamadas linfangiomas quísticos, aparecen muy raramente de forma aislada en el hígado. Casos clínicos. Se presentan dos pacientes femeninas de edad preescolar con marcada hepatomegalia, dependiente de lesiones quísticas multitabicadas, secundarias a malformación linfática quística gigante del hígado, que fueron tratadas en el Hospital Pediátrico Universitario William Soler, La Habana, Cuba. Resultados. En ambos casos el diagnóstico se apoyó en los estudios de imágenes, la laparoscopia y el análisis histopatológico. En un caso el tratamiento fue la hepatectomía derecha, mientras que en el otro se empleó la escleroterapia, ambas con evolución favorable. Conclusión. A pesar de su rareza, este diagnóstico no debe obviarse ante un paciente pediátrico con lesiones hepáticas quísticas. El tratamiento de elección es la resección quirúrgica, pero su indicación y envergadura debe valorarse de forma individualizada

Introduction. Cystic lymphatic malformations, also called cystic lymphangiomas, are very rarely found in the liver. Clinical cases. Two pediatric female preschool-age patients. presented with hepatomegaly due to multi-septated cystic lesions of the liver, who received treatment at Hospital Pediátrico Universitario William Soler, La Habana, Cuba. Results. We report two pediatric cases with giant cystic lymphatic malformation of the liver. In both cases, the diagnosis were based on imaging, laparoscopy and pathology. In one case the treatment was right hepatectomy, whereas in the other, sclerotherapy was performed, both with a favorable outcome. Conclusion. Despite its rarity, this diagnosis should be considered in pediatric patients with hepatic cystic lesions. The recommended treatment is surgical resection, but its indication and extent should be assessed individually for each patient.

Splicing abnormalities caused by a novel mutation in the PHKA2 gene in children with glycogen storage disease type IX / 中华肝脏病杂志

Objective: Glycogen storage disease type IX (GSD-IX) is a rare primary glucose metabolism abnormality caused by phosphorylase kinase deficiency and a series of pathogenic gene mutations. The clinical characteristics, gene analysis, and functional verification of a mutation in a child with hepatomegaly are summarized here to clarify the pathogenic cause of the disease. Methods: The clinical data of a child with GSD-IX was collected. Peripheral blood from the child and his parents was collected for genomic DNA extraction. The patient's gene diagnosis was performed by second-generation sequencing. The suspected mutations were verified by Sanger sequencing and bioinformatics analysis. The suspected splicing mutations were verified in vivo by RT-PCR and first-generation sequencing. Results: Hepatomegaly, transaminitis, and hypertriglyceridemia were present in children. Liver biopsy pathological examination results indicated glycogen storage disease. Gene sequencing revealed that the child had a c.285 + 2_285 + 5delTAGG hemizygous mutation in the PHKA2 gene. Sanger sequencing verification showed that the mother of the child was heterozygous and the father of the child was of the wild type. Software such as HSF3.1 and ESEfinder predicted that the gene mutation affected splicing. RT-PCR of peripheral blood from children and his mother confirmed that the mutation had caused the skipping of exon 3 during the constitutive splicing of the PHKA2 gene. Conclusion: The hemizygous mutation in the PHKA2 gene (c.285 + 2_285 + 5delTAGG) is the pathogenic cause of the patient's disease. The detection of the novel mutation site enriches the mutation spectrum of the PHKA2 gene and serves as a basis for the family's genetic counseling.

Clinical features of Kawasaki disease complicated by macrophage activation syndrome: an analysis of 27 cases / 中国当代儿科杂志

OBJECTIVES@#To investigate the clinical manifestations and laboratory examination results of children with Kawasaki disease complicated by macrophage activation syndrome (KD-MAS), and to provide a basis for identifying early warning indicators for the early diagnosis and treatment of KD-MAS.@*METHODS@#A retrospective study was performed on 27 children with KD-MAS (KD-MAS group) and 110 children with KD (KD group) who were admitted to Wuhan Children's Hospital, Tongji Medical College, Huazhong University of Science and Technology, from January 2014 to January 2022. Clinical and laboratory data were compared between the two groups. The receiver operating characteristic (ROC) curve was used to investigate the value of laboratory markers with statistical significance in the diagnosis of KD-MAS.@*RESULTS@#Compared with the KD group, the KD-MAS group had significantly higher incidence rates of hepatomegaly, splenomegaly, incomplete KD, no response to intravenous immunoglobulin, coronary artery damage, multiple organ damage, and KD recurrence, as well as a significantly longer length of hospital stay (P<0.05). Compared with the KD group, the KD-MAS group had significantly lower levels of white blood cell count, absolute neutrophil count, hemoglobin, platelet count (PLT), erythrocyte sedimentation rate, serum albumin, serum sodium, prealbumin, and fibrinogen (FIB), a significantly lower incidence rate of non-exudative conjunctiva, and significantly higher levels of C-reactive protein, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase (LDH), and serum ferritin (SF) (P<0.05). The ROC curve analysis showed that SF, PLT, FIB, and LDH had high value in the diagnosis of KD-MAS, with areas under the curve (AUC) of 0.989, 0.966, 0.932, and 0.897, respectively (P<0.001), and optimal cut-off values of 349.95 μg/L, 159×109/L, 3.85 g/L, and 403.50 U/L, respectively. The combination of SF, PLT, FIB, and LDH had a larger AUC than PLT, FIB, and LDH alone in the diagnosis of KD-MAS (P<0.05), but there was no significant difference in the AUC between the combination of SF, PLT, FIB, and LDH and SF alone (P>0.05).@*CONCLUSIONS@#KD-MAS should be considered when children with KD have hepatosplenomegaly, no response to intravenous immunoglobulin, coronary artery damage, and KD recurrence during treatment. SF, PLT, FIB, and LDH are of high value in the diagnosis of KD-MAS, especially SF is of great significance in the diagnosis of KD-MAS.

Characteristics of plasma Epstein-Barr virus DNA in children with primary infection / 中华儿科杂志

Objective: To explore the characteristics of plasma Epstein-Barr virus (EBV) DNA in primary infection in pediatric cases. Methods: The laboratory and clinical data of 571 children diagnosed with EBV primary infection in Children's Hospital of Fudan University during September 1st, 2017 to September 30th, 2018 were retrospectively analyzed. According to the results of plasma EBV DNA, they were divided into positive group and negative group. According to the EBV DNA, they were devided into high plasma virol load group and low plasma virol load group. The Chi-square test, Wilcoxon rank sum test were used to compare the differences between groups. Results: Among the 571 children with EBV primary infection, 334 were males and 237 were females. The age of first diagnosis was 3.8 (2.2, 5.7) years. There were 255 cases in positive group and 316 cases in negative group. The percentage of cases with fever,hepatomegaly and (or) splenomegaly, elevated transaminase in the positive group were higher than those in the negative group (235 cases (92.2%) vs. 255 cases (80.7%), χ2=15.22, P<0.001; 169 cases (66.3%) vs. 85 cases (26.9%), χ2=96.80, P<0.001; and 144 cases (56.5%) vs. 120 cases (38.0%), χ2=18.27, P<0.001; respectively).In the positive group, 70 cases were followed up for 46 (27, 106) days, 68 cases (97.1%) turned negative within 28 days, with the exception of 2 cases (2.9%) developed chronic active EBV infection by follow-up revision.There were 218 cases in high plasma viral DNA copies group and 37 cases in low copies group. More cases presented with elevated transaminases in the high plasma viral DNA copies group than those in the low group (75.7% (28/37) vs. 56.0%(116/207), χ2=5.00, P=0.025).Both the positive rate of EBV DNA in peripheral blood leukocytes (84.2% (266/316) vs. 44.7% (255/571), χ2=76.26, P<0.001) and the copies of EBV DNA (7.0×107 (1.3×107, 3.0×108) vs. 3.1×106 (1.6×106, 6.1×106) copies /L, Z=15.23, P<0.001) were higher than that of plasma. Conclusions: In immunocompetent pediatric cases diagnosed as EBV primary infection, cases with positive plasma EBV DNA were prone to have fever, hepatomegaly and (or) splenomegaly, and elevated transaminase than those with negative plasma viral DNA. The plasma EBV DNA usually turns negative within 28 days after initial diagnosis.Most cases with high viral load in plasma showed elevated aminotransferase.

Lysosomal acid lipase deficiency in pediatric patients: a scoping review

Abstract Objective: Lysosomal acid lipase deficiency (LAL-D) is an underdiagnosed autosomal recessive disease with onset between the first years of life and adulthood. Early diagnosis is crucial for effective therapy and long-term survival. The objective of this article is to recognize warning signs among the clinical and laboratory characteristics of LAL-D in pediatric patients through a scope review. Sources: Electronic searches in the Embase, PubMed, Livivo, LILACS, Web of Science, Scopus, Google Scholar, Open Gray, and ProQuest Dissertations and Theses databases. The dataset included observational studies with clinical and laboratory characteristics of infants, children and adolescents diagnosed with lysosomal acid lipase deficiency by enzyme activity testing or analysis of mutations in the lysosomal acid lipase gene (LIPA). The reference selection process was performed in two stages. The references were selected by two authors, and the data were extracted in June 2020. Summary of the findings: The initial search returned 1593 studies, and the final selection included 108 studies from 30 countries encompassing 206 patients, including individuals with Wolman disease and cholesteryl ester storage disease (CESD). The most prevalent manifestations in both spectra of the disease were hepatomegaly, splenomegaly, anemia, dyslipidemia, and elevated transaminases. Conclusions: Vomiting, diarrhea, jaundice, and splenomegaly may be correlated, and may serve as a starting point for investigating LAL-D. Familial lymphohistiocytosis should be part of the differential diagnosis with LAL-D, and all patients undergoing upper gastrointestinal endoscopy should be submitted to intestinal biopsy.

A rare case of mixed adult Hepatoblastoma mimicking as Hepatocellular Carcinoma

@#Hepatoblastoma (HB) is a rare pediatric malignant tumor of the liver. Most of these tumors arise in the embryo and this is usually discernible in the first 3 years of life; thus, its occurrence in the adult population seems to be unusual. We present this case due to its rarity and its potential to mimic other primary liver tumors in adults such as HCC. To the best of our knowledge with literature review, there are only 40 cases of adult HB reported worldwide. In this paper, we report a case of a 49-year-old female, diagnosed with Chronic Hepatitis B, admitted due to abdominal pain. Physical examination revealed hepatomegaly. Liver function test was unremarkable. AFP was elevated at >50,000ng/mI. Triphasic CT scan revealed a hypodense mass in the right lobe of the liver measuring approximately 11 × 11 × 13cm suggestive of HCC. Subsequently, patient underwent right hepatectomy. Pathological examination, however, demonstrated that the tumor showed a malignant neoplasm with epithelial and mesenchymal components consistent with adult HB, mixed type. Since treatment of adult HB is not yet established, studies have suggested that it is logical to follow the treatment protocol for childhood HB. Hence, this patient underwent chemotherapy with Cisplatin, Vincristine and 5-Fluorouracil. The low incidence of HB in adults presents a diagnostic challenge, requiring a high index of suspicion and a thorough evaluation. Since prognosis could be improved with early detection and treatment, it is important for clinicians not to overlook HB.

Se diagnosticó con MW refractaria y es candidato para recibir Ibrutinib; no disponible en nuestro me - dio. Conclusión: La escasa casuística de enfermedad de MW en Honduras dificulta el diagnóstico oportuno y tratamiento óptimo en nuestro medio...(AU)

Enfermedad de Caroli: revisión sistemática de la literatura / Characterization of patients with Caroli's disease: Systematic review

Resumen Introducción: La enfermedad de Caroli es un trastorno congénito poco usual, el cual cursa con dilatación segmentaria multifocal de los conductos biliares intrahepáticos. Fue descrita por Jacques Caroli en 1958 como una dilatación sacular, segmentada o fusiforme de los ductos biliares intrahepáticos. Objetivo: Caracterizar a la población que ha padecido la enfermedad de Caroli. Metodología: Revisión sistemática de la literatura. Resultados: Se analizaron 66 artículos, el grupo de edad más afectado es los menores de 10 años, en el que se evidenció una mayor prevalencia en varones, y se encontró asociado con otras comorbilidades como el riñón poliquístico (20 %). La manifestación más frecuente fue la hepatomegalia (44,7 %), seguido de la fiebre (42,4 %) y el dolor abdominal en el hipocondrio derecho (41,2 %). Como método diagnóstico más utilizado se encontraba la resonancia magnética (73,8 %); dentro de los hallazgos predominó la dilatación intrahepática (76,5 %) y el manejo más empleado fue la antibioticoterapia para tratar las recurrencias por colangitis. Conclusión: La enfermedad de Caroli tiene una baja prevalencia, se presenta con mayor frecuencia en el continente americano, afecta principalmente a la primera década de la vida, tiene predilección por el sexo masculino y se caracteriza por una dilatación de los conductos intrahepáticos que pueden afectar a otros órganos como los riñones, lo que produce quistes renales.

Abstract Caroli's disease (CD) is a rare congenital disease, which presents with multifocal segmental intrahepatic bile duct dilatation. It was first described by Jacques Caroli in 1958 as a saccular or fusiform dilatation of the intrahepatic bile ducts. Objective: To characterize the population that has been diagnosed with Caroli's disease. Materials and methods: Systematic review. Results: 66 articles were analyzed. The age group most affected was children under 10 years old, where a higher prevalence was evidenced in males. This condition was associated with other comorbidities such as polycystic kidney in 20%. The most frequent manifestation was hepatomegaly (44.7%), followed by fever (42.4%), and abdominal pain in the right upper quadrant (41.2%). The most used diagnostic method was magnetic resonance imaging in 73.8% of the sample. The findings showed predominance of intra-hepatic dilatation in 76.5%. The most widely used treatment was antibiotic therapy to treat recurrences due to cholangitis. Conclusion: Caroli's disease has an extremely low incidence and occurs more frequently in the American continent, affecting mainly patients in the first decade of life, with a predilection for the male sex. It is characterized by a dilatation of the intrahepatic ducts that can affect other organs such as the kidneys, causing renal cysts.

Rare and unknown canine systemic mastocytosis: clinical and laboratory features of an aberrant c-Kit mutation neoplasia / A rara e desconhecida mastocitose sistêmica canina: características clínicas e laboratoriais de uma neoplasia aberrante na mutação c-Kit

Systemic mastocytosis (SM) pathology is extremely rare in canine practice, with insufficient reported data. The knowledge of the clinical behavior of this pathology is scarce. In human medicine, SM has been widely investigated, being defined as a rare hematopoietic disorder by the World Health Organization (2016), within the type of myeloproliferative neoplasms. Herein, we describe a systemic mastocytosis case in a Portuguese Serra-da-Estrela dog, where a cutaneous grade III/high-grade MCT was also diagnosed. The clinical decline of the animal and owner's insistence throughout anamnesis that the dog was markedly different after the cytologic exam performed in another clinic, along with both severe eosinophilia and hepatomegaly, led to the clinical suspicion of SM. The animal passed away 7 days later. Post-morteminvestigation confirmed SM pathology, and a deletion of 15 base pairs change on c-Kit gene exon 11 was identified. Contemplating the low number of cases described in the literature, this publication aims to disclose clinical and laboratory features of rare and poorly described canine SM, taking into consideration human outcomes described in the literature.(AU)

A patologia da mastocitose sistêmica (SM) é extremamente rara na prática clínica canina, com escassos casos descritos na literatura científica. O conhecimento do comportamento clínico desta patologia é mínimo. Na medicina humana, a SM tem sido amplamente investigada, sendo definida como uma doença hematopoiética rara pela Organização Mundial da Saúde (2016), dentro do tipo de neoplasias mieloproliferativas. Descrevemos aqui um caso de mastocitose sistêmica num cão Serra-da-Estrela português, diagnosticado também com um mastocitoma cutâneo grau III / alto grau. O declínio clínico do animal e a insistência do proprietário durante a anamnese de que o cão estava marcadamente diferente após o exame citológico realizado em outra clínica, juntamente com eosinofilia e hepatomegalia graves, levantaram a suspeita clínica de SM. O animal faleceu 7 dias depois. A investigação post-mortem confirmou a patologia SM, e o estudo molecular revelou uma deleção de 15 pares de bases no exon 11 do gene c-Kit. Contemplando o baixo número de casos descritos na literatura, o objetivo desta publicação é divulgar características clínicas e laboratoriais de SM canina, levando em consideração informações clínicas descritas em humanos.(AU)

Acute liver failure due to radiographically occult infiltration of urothelial cancer

Introduction Acute liver failure (ALF) due to diffuse infiltrating solid malignancy without any focal lesions on radiographic imaging is rare. Case report A 70-year-old man was admitted due to mental confusion, abdominal pain, and ALF. Three years before, he had undergone a left nephrectomy for urothelial carcinoma followed by adjuvant chemotherapy. The abdominal computed tomography (CT) showed hepatomegaly and ascites. Ascitic fluid had transudate characteristics, with no malignant cells. Percutaneous liver biopsy (LB) showed diffuse liver infiltration of metastatic urothelial carcinoma. The patient rapidly deteriorated and died in a week due to ALF. Discussion History of solid cancer and hepatomegaly and/or liver failure without other obvious explanation should encourage to perform LB. Conclusion LB is warranted to avoid misdiagnosis, prolonged hospital stays, and delay in palliative care.

Hepatoesplenomegalia relacionada a linfoma de Burkitt en paciente pediátrico / Hepatoesplenomegalia related to Burkitt´s lymphoma in a pediatric patient

RESUMEN El linfoma de Burkitt, se trata de un subtipo poco frecuente del linfoma no Hodgkin, con elevada frecuencia en aquellos pacientes con sida. La hepatoesplenomegalia es un signo clínico de gran importancia para el diagnóstico oportuno de algunas patologías; entre los mecanismos de formación de la hepatoesplenomegalia se encuentra la infiltración celular, ocasionada por la migración de células tumorales. Se presenta por inflamaciones debido a la presencia de infecciones por virus o bacterias las cuales son muy comunes en pacientes con sida. Se presentó un caso de un paciente masculino de 4 años, diagnosticado con VIH positivo, con la configuración correspondiente de criterios clínicos en clasificación C para sida. El cual desarrolló a nivel de cavidad oral un Burkitt primario, que se acompañó de hepatoesplenomegalia. Se pretendió describir la relación y el comportamiento de este tipo de linfoma con la hepatoesplenomegalia, así como la repercusión a nivel del sistema estomatognático, a nivel sistémico y el plan de tratamiento. Por el cuadro clínico e inmunológico del paciente estudiado, se planteó un pronóstico reservado por presentar un cuadro clínico infrecuente, en el que se observó Burkitt; tanto a nivel del sistema estomatognático como a nivel abdominal. Se hizo necesario realizar un diagnóstico oportuno y certero para iniciar el tratamiento a tiempo, se comenzó inmediatamente con tratamiento (AU).

ABSTRACT Burkitt lymphoma (BL) is a rare subtype of non-Hodgkin lymphoma, with high frequency in those patients with AIDS. Hepatosplenomegaly is a clinical sign of great importance for the timely diagnosis of some pathologies; cellular infiltration is found among the mechanisms of hepatosplenomegaly formation; it is caused by the migration of tumor cells. It emerges by inflammations due to the presence of infections by virus or bacteria which are very common in patients with AIDS. The authors present the case of a male patient, aged 4 years, with a positive HIV diagnosis, and the correspondent configuration of clinical criteria in C classification for AIDS, who developed a primary Burkitt lymphoma at the level of oral cavity We present the case of a 4-year-old male patient diagnosed with HIV positive, with the corresponding configuration of clinical criteria in classification C for AIDS; who developed a primary LB at the oral cavity level that was accompanied by hepatosplenomegaly. The authors pretended to describe the relation and behavior of this kind of lymphoma with hepatosplenomegaly, and also the repercussion at the stomatognathic level, at the systemic level and the treatment plan. Due to the clinical and immunological characteristics of the studied patient a reserved prognosis was given because of presenting infrequent clinical characteristics in which a Burkitt was observed both, at the stomatognathic and at the abdominal level. It was necessary to make an opportune and accurate diagnosis to begin the treatment on time (AU).

Estudios de la naturaleza de la Efectividad y Dirección Funcional de Suplemento Biológicamente Activo en el Tratamiento Integral de la Hepatitis Alcohólica Aguda / Nature Studies of the Effectiveness and Functional Direction of Biologically Active Supplement in Comprehensive Treatment of Acute Alcoholic Hepatitis

The article examines the influence of the Biologically Active Dietary Supplement (BADS) "Oleopren Hepa" as a hepatoprotective effect in the comprehensive treatment of acute alcoholic hepatitis. During the study, the authors obtained evidence of the effectiveness and functional orientation of the BADS. The materials for the research are the data obtained during the examination and treatment of 60 patients with acute alcoholic hepatitis. All examined patients were divided into 2 groups: 1st group (main), which received dietary supplements; the 2nd group (control) who did not receive this supplement. The average age of patients was 38.7 ± 9.3 years. The study was carried out based on the gastroenterological department of the city clinical hospital. As a result of the use of BADS in the comprehensive therapy of patients with acute alcoholic hepatitis, hepatomegaly was significantly reduced, and a decrease in the levels of total bilirubin, AsAt, AlAT, GGTP and cholesterol was observed. Additional intake of a specialized product enhanced the hepatoprotective effect of the main treatment. According to the tested biochemical parameters, the dynamics were better than in the control group. The use of the BADS, in addition to comprehensive therapy, increases the effectiveness of treatment of acute alcoholic hepatitis.

Síndrome de Budd-Chiari: etiología, manejo y resultados en una cohorte de 35 pacientes del Hospital Pablo Tobón Uribe / Budd-Chiari Syndrome: Etiology, management, and outcomes in a study of 35 patients at the Hospital Pablo Tobón Uribe

Resumen El síndrome de Budd-Chiari (Budd-Chiari syndrome, BCS) es una entidad rara, definida por la obstrucción del flujo venoso del hígado y corresponde a una condición heterogénea tanto en presentación como en manejo terapéutico. A continuación, presentamos un estudio retrospectivo de pacientes con diagnóstico de BCS, atendidos por el grupo de hepatología del el Hospital Pablo Tobón Uribe. Los resultados se expresan como proporciones en las variables categóricas y como medias y rangos para las variables continuas. La edad promedio de presentación fue de 37,7 años y no hubo preponderancia por el género. Los principales síntomas fueron dolor abdominal (91,4 %), ascitis (71,4 %) y hepatomegalia (60 %). Asimismo, 11 pacientes (31,4 %) presentaron hipercoagulabilidad primaria, mientras que en 7 (20 %) se encontró algún síndrome mieloproliferativo. Además, 6 (17,1 %) tenían neoplasias extrahepáticas: 3 con compresión mecánica y 3 por hipercoagulabilidad asociada; solo en 1 caso se documentaron membranas en la vena cava inferior. Y en 5 casos no fue posible determinar la causa de trombosis. De igual forma, 32 pacientes (91,4 %) recibieron anticoagulación como primer manejo; solo 4 sujetos fueron remitidos a procedimientos: 2 a angioplastia, 1 a derivación portosistémica intrahepática transyugular (Transjugular Intrahepatic Portosystemic Shunt, TIPS) y 1 a trasplante ortotópico hepático (TOH). Luego de ello, 17 (48,5 %) recibieron procedimientos invasivos como segunda línea: 8 (22,8 %) se condujeron a angioplastia y endoprótesis (stent), 5 (14,29 %) a TIPS y 4 necesitaron TOH. Así, los 6 pacientes que se llevaron a TIPS no necesitaron trasplante hepático. El BCS continúa siendo una condición poco frecuente que afecta la salud de personas jóvenes, tanto hombres como mujeres, con una presentación clínica heterogénea. Sin embargo, en la mayoría de los casos ocurre por una causa desencadenante clara, entre las cuales predominan las trombofilias y los síndromes mieloproliferativos. El uso de medidas terapéuticas invasivas, especialmente de la selección temprana de los enfermos que se benefician de TIPS, ha cambiado la historia natural y el pronóstico de este grupo de pacientes.

Abstract Budd-Chiari syndrome (BCS) is a rare disorder characterized by the obstruction of the veins of the liver. Both its presentation and therapeutic management are heterogenous. The following is a retrospective study of patients diagnosed with BCS treated by the hepatology service at the Hospital Pablo Tobón Uribe. The results of the categorical variables are expressed as proportions and the continuous variables as means and ranges. The average age of onset of this disease was 37.7 years and it was not predominant in neither sex. The most common symptoms were abdominal pain (91.4%), ascites (71.4%) and hepatomegaly (60%). Out of 35 patients, 11 (31.4%) had primary hypercoagulability, 7 (20%) had some myeloproliferative disorder, 6 (17.1%) had extrahepatic malignancies -3 with mechanical compression and 3 due to associated hypercoagulability-, and 1 case had a membranous obstruction of the inferior vena cava. 32 patients (91.4%) received anticoagulation as first-line therapy and only 4 were taken to surgery: 2 to angioplasty, 1 to transjugular intrahepatic portosystemic shunt (TIPS) and 1 to orthotopic liver transplantation (OLT). On the other hand, 17 (48.5%) individuals underwent invasive procedures as a second-line therapy, of which 8 (22.8%) underwent angioplasty and stenting, 5 (14.29%) underwent TIPS and 4 needed OLT. The 6 patients who were taken to TIPS did not need liver transplants. Budd-Chiari syndrome remains a rare condition affecting the health of young men and women alike, with a heterogeneous clinical presentation but, in most cases, with a clear trigger where thrombophilic and myeloproliferative disorders predominate. The use of invasive therapeutic measures, especially the early selection of patients who may benefit from TIPS, has changed the natural course and prognosis of this group of patients.

Ascariasis hepatobiliar en una lactante con desnutrición severa: reporte de caso / Hepatobiliary ascariasis in severely malnourished infant: case report

Resumen La Ascariasis es la geohelminitiasis más común del mundo, catalogándose como una enfermedad tropical desatendida, que puede causar compromiso pulmonar, gastrointestinal, hepatobiliar y nutricional. Se presenta el caso inusual de una lactante procedente de una zona de extrema pobreza quien consultó por fiebre, vómito, ausencia de deposiciones, distensión y dolor abdominal. Fue diagnosticada con pseudoobstrucción intestinal, desnutrición severa, choque séptico de origen intraabdominal, retraso del neurodesarrollo y deprivación psicoafectiva, cuyas imágenes reportaron ascariasis hepatobiliar y granulomas hepáticos calcificados y abscedados, con infestación severa por Ascaris lumbricoides. Recibió manejo antibiótico y antiparasitario con recuperación exitosa. En nuestro medio, las infecciones por helmintos son causa frecuente de anemia, retraso cognitivo y del crecimiento en niños en edad escolar. Sin embargo, la infestación y complicaciones hepatobiliares como colangitis, colecistitis, pancreatitis, litiasis biliar y hepatitis abscedada son inusuales en menores de dos años. A través de este caso se pretende resaltar la presentación atípica de la enfermedad en lactantes e incitar al fortalecimiento de las intervenciones en salud pública. MÉD.UIS.2020;33(1):67-72.

Abstract Ascariasis is the most common geohelminitiasis in the world. It is categorized as an unattended tropical disease, which can cause pulmonary, gastrointestinal, hepatobiliary and nutritional compromise. We present the unusual case of an infant from an extreme poverty area presenting fever, vomiting, absence of bowel movements, bloating and abdominal pain. She was diagnosed with intestinal pseudoobstruction, severe malnutrition, abdominal septic shock, neurodevelopmental delay and emotional deprivation. The images reported hepatobiliary ascariasis and calcified and abscessed hepatic granulomas, with severe infestation by Ascaris lumbricoides and Trichuris trichiura. She was treated with antibiotics and antiparasitic agents with successful recovery. In our environment, helminth infections are a frequent cause of anemia, stunting and neurodevelopmental delay in school-age children. However, infestation and hepatobiliary complications such as cholangitis, cholecystitis, pancreatitis, biliary lithiasis and hepatic abscess are unusual in children under two years old. Through this case, it is intended to highlight the atypical presentation of this disease at the age of this patient and encourage the strengthening of public health interventions.

Acidemia propiónica: una causa sumamente rara de linfohistiocitosis hemofagocítica en un lactante / Propionic acidemia: an extremely rare cause of hemophagocytic lymphohistiocytosis in an infant

La linfohistiocitosis hemofagocítica (LHH) puede ser primaria (hereditaria) o secundaria a infecciones, tumores malignos, trastornos reumatológicos, síndromes de inmunodeficiencia y metabolopatías. Se informaron casos de intolerancia a la proteína lisinúrica, deficiencia de múltiples sulfatasas, galactosemia, enfermedad de Gaucher, síndrome de Pearson y galactosialidosis. No se sabe cómo se desencadena la LHH en las metabolopatías. Se diagnosticó LHH en un lactante de 2 meses con letargo, palidez, alimentación deficiente, hepatoesplenomegalia, fiebre y pancitopenia, y se instauró el protocolo HLH-2004. Se realizaron, en conjunto, análisis para detectar mutaciones genéticas y pruebas metabólicas; los resultados fueron negativos para las mutaciones genéticas de LHH primaria, pero se detectaron hiperamoniemia y concentración elevada de metilcitrato. Se diagnosticó acidemia propiónica. Aquí informamos sobre un caso de LHH secundaria a acidemia propiónica. Es posible la realización simultánea de pruebas de detección de trastornos metabólicos y de mutaciones genéticas para el diagnóstico temprano en los lactantes con LHH

Hemophagocytic lymphohystiocytosis (HLH) may be primary (inherited/familial) or secondary to infections, malignancies, rheumatologic disorders, immune deficiency syndromes and metabolic diseases. Cases including lysinuric protein intolerance, multiple sulfatase deficiency, galactosemia, Gaucher disease, Pearson syndrome, and galactosialidosis have previously been reported. It is unclear how the metabolites trigger HLH in metabolic diseases. A 2-month-old infant with lethargy, pallor, poor feeding, hepatosplenomegaly, fever and pancytopenia, was diagnosed with HLH and the HLH-2004 treatment protocol was initiated. Analysis for primary HLH gene mutations and metabolic screening tests were performed together; primary HLH gene mutations were negative, but hyperammonemia and elevated methyl citrate were detected. Propionic acidemia was diagnosed with tandem mass spectrometry in neonatal dried blood spot. We report this case of HLH secondary to propionic acidemia. Both metabolic disorder screening tests and gene mutation analysis may be performed simultaneously especially for early diagnosis in infants presenting with HLH.
