[Clinical analysis of allogeneic hematopoietic cell transplantation in 9 patients with hematological malignancies complicated by Gilbert's syndrome].

From January 1, 2013, to March 1, 2024, nine patients with hematological malignancies complicated by Gilbert's syndrome in Peking University People's Hospital underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT). The patients comprised seven male and two female cases, with a median age of 38 (13-60) years old. Among them, three cases were acute myeloid leukemia, three cases were acute lymphocytic leukemia, two cases were myelodysplastic syndrome, and one case was chronic myelomonocytic leukemia. None of the patients had viral hepatitis. Of the nine cases, seven cases received the Bu-Cy+ATG regimen, while the other two cases received the TBI-Cy+ATG regimen (Bu, busulfan; Cy, cyclophosphamide; ATG, antithymocyte immunoglobulin; and TBI, total body irradiation). All patients achieved neutrophil engraftment, and eight received platelet engraftment. The median total bilirubin level was 45.4 (22.5-71.2) µmol/L before transplantation and 22.0 (18.0-37.2) µmol/L on -1d of preconditioning. The total bilirubin level on +20d after the transplantation of eight patients decreased compared with the baseline level before transplantation. Moreover, one patient had a transient increase in the total bilirubin level on +5d after transplantation, which was considered to be attributed to the toxicity of Bu. No patients were complicated by hepatic veno-occlusive disease. The median follow-up time was 739 (42-2 491) days. During the follow-up period, one patient died of recurrence, and the remaining eight patients had disease-free survival events.

Identification of a novel splice variant in SEC23B gene in a patient with concomitant presence of congenital dyserythropoietic anemia II and Gilbert's syndrome.

BACKGROUND: Congenital dyserythropoietic anemia Ⅱ (CDA Ⅱ) is a rare inherited disorder of defective erythropoiesis caused by SEC23B gene mutation. CDA Ⅱ is often misdiagnosed as a more common type of clinically related anemia, or it remains undiagnosed due to phenotypic variability caused by the coexistence of inherited liver diseases, including Gilbert's syndrome (GS) and hereditary hemochromatosis. METHODS: We describe the case of a boy with genetically undetermined severe hemolytic anemia, hepatosplenomegaly, and gallstones whose diagnosis was achieved by targeted next generation sequencing. RESULTS: Molecular analysis revealed a maternally inherited novel intronic variant and a paternally inherited missense variant, c.[994-3C > T];[1831C > T] in the SEC23B gene, confirming diagnosis of CDA Ⅱ. cDNA analysis verified that the splice acceptor site variant results in two mutant transcripts, one with an exon 9 skip and one in which exons 9 and 10 are deleted. SEC23B mRNA levels in the patient were lower than those in healthy controls. The patient was also homozygous for the UGT1A1*6 allele, consistent with GS. CONCLUSION: Identification of the novel splice variant in this study further expands the spectrum of known SEC23B gene mutations. Molecular genetic approaches can lead to accurate diagnosis and management of CDA Ⅱ patients, particularly for those with GS coexisting.

Acalculous Cholecystitis as a Complication of Primary Epstein-Barr Virus Infection: A Case-Based Scoping Review of the Literature.

Primary Epstein-Barr virus (EBV) infection manifests with diverse clinical symptoms, occasionally resulting in severe complications. This scoping review investigates the rare occurrence of acute acalculous cholecystitis (AAC) in the context of primary EBV infection, with a focus on understanding its prevalence, clinical features, and underlying mechanisms. The study also explores EBV infection association with Gilbert syndrome, a condition that potentially exacerbates the clinical picture. Additionally, a case report of an 18-year-old female presenting with AAC and ascites secondary to EBV infection enhances the review. A comprehensive literature review was conducted, analyzing reported cases of AAC secondary to EBV infection. This involved examining patient demographics, clinical presentations, laboratory findings, and outcomes. The search yielded 44 cases, predominantly affecting young females. Common clinical features included fever, cervical lymphadenopathy, tonsillitis/pharyngitis, and splenomegaly. Laboratory findings highlighted significant hepatic involvement. The review also noted a potential link between AAC in EBV infection and Gilbert syndrome, particularly in cases with abnormal bilirubin levels. AAC is a rare but significant complication of primary EBV infection, primarily observed in young females, and may be associated with Gilbert syndrome. This comprehensive review underscores the need for heightened clinical awareness and timely diagnosis to manage this complication effectively.

Prolonged Jaundice in a Premature Breastfed Infant With Gilbert's Syndrome.

INTRODUCTION: Neonatal jaundice and prematurity pose significant barriers to breastfeeding in the first days of life. There is limited literature exploring the relationship between prolonged jaundice in breastfed infants and Gilbert's (Meulengraght) syndrome. This case study describes the diagnostic and therapeutic challenges associated with Gilbert's syndrome in a late preterm breastfed infant born in Germany. MAIN ISSUE: In this case report, an infant born to a primipara woman presented at 3 weeks postpartum to an International Board Certified Lactation Consultant. The initial assessment revealed a late preterm infant with inadequate weight gain and jaundice. The dyad received breastfeeding support and eventually achieved adequate weight gain; however, the infant's jaundice persisted. MANAGEMENT: The consulting midwife suggested that the persistent jaundice was "breastmilk jaundice" and recommended temporarily interrupting breastfeeding. Due to a suspected family history of Gilbert's Syndrome, the dyad was referred, instead, to a pediatric gastroenterologist. Pathologic liver disease was excluded, and genetic testing confirmed Gilbert's Syndrome. At 6 months of age, the dyad was successfully breastfeeding and beginning complementary feeding. CONCLUSION: Genetic testing for Gilbert's Syndrome should be considered for infants with prolonged jaundice and positive family history. Interruption or cessation of breastfeeding are not evidence-based recommendations, and current guidelines do not support these practices. Lactation professionals play a critical role in the management of breastfeeding for preterm infants with prolonged jaundice and should refer to specialists to rule out pathologic etiologies.

Cardiovascular and metabolic effects of hyperbilirubinemia in a cohort of Italian Olympic athletes.

INTRODUCTION: Bilirubin was supposed to have cardio-metabolic protective role by signaling functions. Indeed, mild hyperbilirubinemia has immunosuppressive and endocrine activities and may offer protection against oxidative stress-mediated diseases. Gilbert syndrome (GS) has been hypothesized to provide cardio-metabolic benefits. OBJECTIVE: To investigate the prevalence of hyperbilirubinemia and its cardio-metabolic effects in a cohort of elite Italian athletes engaged in different sports disciplines. METHODS: We enrolled 1492 elite athletes (age 25.8 ± 5.1) practising different disciplines (power, skills, endurance, and mixed) underwent blood, echocardiographic, and exercise tests. GS was diagnosed per exclusionem in athletes with isolated asymptomatic unconjugated hyperbilirubinemia. RESULTS: GS was highlighted in 91 athletes (6%; globally 9% male and 2.4% female); 82% were males (p < 0.0001) showing higher indirect bilirubin (0.53 ± 0.4 vs. 0.36 ± 0.24 mg/dL in females, p < 0.0001). GS athletes had fewer platelets (201 ± 35 vs. 214 ± 41, p = 0.01), higher iron (male: 124 ± 44 vs. 100.9 ± 34 mcg/dL, p < 0.0001; female: 143.3 ± 35 vs. 99.9 ± 42 mcg/dL, p < 0.0001), and lower erythrocyte sedimentation rate, (1.93 ± 0.9 vs. 2.80 ± 2.7 mm/H, p = 0.03). At multivariate analysis, male (OR 3.89, p = 0.001) and iron (OR 3.47, p = 0.001) were independently associated with GS. No significant differences were found in cardiac remodeling, heart rate, blood pressure, arrhythmias, or power capacity at stress test. Endurance athletes (313) presented higher total (p = 0.003) and indirect bilirubin (p = 0.001). CONCLUSION: Bilirubin has several metabolic effects (including immunosuppressive and endocrine) and plays a role in regulating antioxidant pathways exercise-related with hematological consequences but seems not to affect significantly cardiovascular remodeling. Endurance athletes present higher bilirubin concentrations, likely as an adaptive mechanism to counteract increased oxidative stress.

Olfactory reference plus Truman symptoms in one patient with Gilbert syndrome and antiphospholipid antibodies (Hughes disease) secondary to probable chronic Lyme neuroborreliosis.

After reading an article in the journal, regarding affective disorders in patients with rare illnesses, the authors would like to discuss a case of non-affective psychosis, presenting with olfactory reference and Truman symptoms, in a patient with three unusual conditions: Gilbert disease, Hughes syndrome and Lyme neuroborreliosis.

A Novel SPTA1 Mutation in a Patient with Hereditary Spherocytosis without a Family History and Coexisting Gilbert's Syndrome.

Most patients with hereditary spherocytosis (HS) have a family history of disease, while those without such a history are difficult to diagnose. We herein report a case of HS with no family history harboring a novel heterozygous mutation of SPTA1, c.2161G>A (p.E721K), and a homozygous polymorphism of UGT1A1*6. In silico analyses suggested that the mutation might contribute to the pathogenesis of HS. The coexistence of HS and Gilbert's syndrome increases the risk of gallstones. Therefore, splenectomy, alone or in combination with cholecystectomy, is recommended. The determination of genetic diathesis provides useful information for the management of hemolytic anemia.

A Novel α-Spectrin Pathogenic Variant in Trans to α-Spectrin LELY Causing Neonatal Jaundice With Hemolytic Anemia From Hereditary Pyropoikilocytosis Coexisting With Gilbert Syndrome.

Hereditary pyropoikilocytosis is a subtype of hereditary elliptocytosis because of biallelic mutations of SPTA1, SPTB, and EPB41. The authors present a proband with neonatal jaundice and hemolytic anemia, with poikilocytosis in the blood film. Targeted next-generation sequencing identified Q267del trans to the αLELY allele in SPTA1. In addition, the proband presented coexisting Gilbert syndrome as determined by homozygous mutation of UGT1A1. Investigation of 13 relatives and his sibling revealed that only his sibling showed the same phenotype and genotype as the proband. This is the first report of molecular confirmation of coexisting hereditary pyropoikilocytosis and Gilbert syndrome and a novel mutation in SPTA1.

Hereditary Spherocytosis Associated with Gilbert Syndrome Diagnosed with Liver Biopsy Examination and Exome Sequencing.

Depending on which part of the physiological pathway is affected by the pathology, jaundice is classified into three categories: pre-hepatic/hemolytic, hepatic/hepatocellular, and post-hepatic/cholestatic. With routine laboratory tests, most cases of jaundice can be etiologically diagnosed. However, exceptions do occur. Here, we present a case of a 14-year girl who presented with intermittent jaundice for one year that could not be diagnosed with a routine protocol. Her laboratory tests showed a moderate impairment of liver function and a positive osmotic fragility test. Computed tomography scan of her upper abdomen revealed multiple gallbladder stones and splenomegaly. With the help of liver pathological examination and exome sequencing, this patient was finally diagnosed as hereditary spherocytosis combined with Gilbert syndrome.

Carbon monoxide breath test assessment of mild hemolysis in Gilbert's syndrome.

BACKGROUND: Mild hemolysis is difficult to determinate by traditional methods, and its role in Gilbert's syndrome (GS) is unclear. The main aims were to inspect the erythrocyte (RBC) survival in GS by using Levitt's carbon monoxide (CO) breath test and to assess its contribution to unconjugated hyperbilirubinemia. METHODS: Fifty subjects with GS and 1 with type-II Crigler-Najjar syndrome (CN2) received RBC lifespan measurement with Levitt's CO breath test. Mean RBC lifespan was compared with normal referral value. Correlations of serum total bilirubin (TB) with RBC lifespan, blood panel data, demographic factors, and uridine diphosphate glucuronosyltransferase (UGT1A1) mutation load were calculated by Spearman analysis. Susceptibility factors for mild hemolysis were analyzed by multivariate regression analysis. RESULTS: The mean RBC lifespan of the GS subjects was significantly shorter than the normal reference value (95.4 ±â€Š28.9 days vs 126 days; t = -7.504, P < .01), with 30.0% below the lower limit of the normal reference range (75 days). The RBC lifespan of the participant with CN2 was 82 days. Serum TB correlated positively with UGT1A1 mutation load (γ = 0.281, P = .048), hemoglobin (γ = .359, P = .010) and hematocrit (γ = 0.365, P = .010), but negatively with RBC lifespan (γ = -0.336, P = .017). No significant susceptibility factors for mild hemolysis were found. CONCLUSIONS: The results indicate that mild hemolysis indeed, exists in a portion of patients with GS and might serve as an important contributor to unconjugated hyperbilirubinemia in addition to UGT1A1 polymorphism. Further studies on the mechanism and the potential risks in various medical treatments might be wanted.

Study of Gilbert's Syndrome-Associated UGT1A1 Polymorphism in Jaundiced Neonates of ABO Incompatibility Hemolysis Disease.

OBJECTIVE: This study aimed to assess the probable relationship between icter in neonates with ABO incompatibility hemolysis and UGT1A1 gene polymorphism. STUDY DESIGN: There were 65 ABO hemolytic disease of the newborn (HDN) neonates of full term in the study group and 82 non-ABO HDN neonates of full term in the compared group. We tested the UGT1A1 gene mutation of neonates of ABO HDN and non-ABO HDN. We compared the incidence of hyperbilirubinemia between neonates with and without UGT1A1 mutations in the ABO HDN and non-ABO HDN, to determine the relationship between icter in neonates with ABO HDN and UGT1A1 gene polymorphism. SPSS 13.0 were used to analyze those two groups' data. RESULTS: There was statistically significant difference of the serum bilirubin level between the Gly71Arg homozygous and no mutation group in the ABO HDN patients (p < 0.05). When hyperbilirubinemia was defined as serum bilirubin concentration >342 µmol/L, the incidence of hyperbilirubinemia between patients of UGT1A1 and non-UGT1A1 mutations in the ABO HDN group was significantly different (p < 0.05). But in the non-ABO HDN group, no significant difference was found. CONCLUSION: Individuals with Gly71Arg homozygous contributed to their hyperbilirubinemia in ABO HDN patients.

The frequency, clinical course, and health related quality of life in adults with Gilbert's syndrome: a longitudinal study.

BACKGROUND: Gilbert syndrome (GS) is an autosomal recessive inherited disorder of bilirubin glucuronidation which has not been investigated in Egypt. This longitudinal study investigated the frequency, clinical course, genetic profile and health related quality of life in Egyptian adults. METHODS: An initial cross-sectional study was conducted to assess the frequency of Gilbert syndrome among Egyptian adults. Subjects fulfilling the criteria of GS were enrolled into the study and prospectively followed for the clinical features, risk factors for hyperbilirubinemia, health related quality of life [Short form-36 Health Survey version 2 (SF-36v2) and Chronic Liver Disease Questionnaire (CLDQ)], vitamins assessment and UGT1A1 polymorphisms. RESULTS: One hundred and one subjects fulfilled the criteria of GS with a prevalence of 8.016%. Recurrent jaundice was the only presentation in 47 (56.627%) GS subjects and jaundice was associated with abdominal pain, dyspepsia or loss of appetite in 54 (53.465%) subjects. A significant difference in 25-Hydroxyvitamin D3 levels was detected between GS patients and control subjects (P <  00001). Twelve subjects with GS developed significant unconjugated bilirubinemia during direct antiviral therapy (DAAs) therapy for HCV despite achieving sustained virologic response. Pregnancy was associated with significant exacerbation of unconjugated bilirubin which persisted through pregnancy. Risk factors for clinical jaundice included general anesthesia, pregnancy, fasting > 12 h, pregnancy, and low calorie weight losing plans, systemic infections, and intensive physical effort. During jaundice attacks, subjects with GS had significant differences in vitality, role emotional, social functioning, worry and general health domains of the SF-36v2 and CLDQ compared to controls. The homozygous polymorphism A(TA)7TAA was the most frequent polymorphism in Egyptians with GS. CONCLUSION: Gilbert syndrome is a frequent inherited disorder in Egypt. In a substantial percentage of subjects with GS, episodes of jaundice are associated with other symptoms and nutritional deficiencies which result in impairment of HRQOL. Screening, counseling, monitoring and individualized health care are recommended for subjects with GS in the setting of anesthesia, pregnancy, treatment with DAAs, deliveries, surgery and weight loss plans.

[Splenectomy in hemolitic disorders. Influence of Gilbert's disease in the occurrence of biliary complications]. / Esplenectomía en enfermedades hemolíticas. Influencia de la enfermedad de Gilbert en la aparición de complicaciones biliares.

INTRODUCTION: In patients with hemolytic disorders (HD) splenectomy is recommended between 6-12 years. A higher risk of biliary complications (BC) has been described in those with associated Gilbert's disease (GD), but the ideal surgical age has not been stablished yet. Our aim is to quantify the risk of BC in patients with HD and GD to assess the benefit of early splenectomy. MATERIAL AND METHODS: Retrospective study of splenectomies performed in patients with HD between 2000-2017. The incidence of BC, its clinical consequences (admission or invasive treatment) and time of onset were analyzed. Two groups were considered: patients with GD and without GD. Survival curves were obtained and compared with log-rank test. RESULTS: Fourty-four patients underwent splenectomy, 15 of them (34.1%) with HD+GD. The median age at surgery was 10.3 years (range 5.4-14.8). Twenty-nine (65.9%) had BC. Half of the patients with GD had BC before 8 years vs. 10,5 years in the cases without GD (log-rank 3.9, p= 0.05). Patients with GD had more BC (86.7% vs. 55.2%; Chi2= 4.37, p= 0.037). In the HD+GD group, 8 cases (53%) required admission vs.8 patients (31%) in the group HD without GD (Chi2= 2, p= 0.1). Invasive treatment was performed in 2 patients (13%) in the HD+GD group and 2 others (7.6%) in the group HD without GD (Chi2= 0.3, p= 0.6). CONCLUSIONS: In our series, the BC incidence was higher in patients with HD and GD. There was a trend towards an earlier presentation of BC in this group, but neither this data nor its clinical consequences allow us to recommend early splenectomy.

INTRODUCCION: En pacientes con enfermedades hemolíticas (EH) se recomienda esplenectomía entre 6-12 años. En aquellos con enfermedad de Gilbert (EG) asociada se ha descrito mayor riesgo de complicaciones biliares (CB), sin establecerse edad quirúrgica óptima. Nuestro objetivo es cuantificar el riesgo de CB en pacientes con EH y EG para valorar el beneficio de esplenectomía temprana. MATERIAL Y METODOS: Estudio retrospectivo de las esplenectomías realizadas en pacientes con EH entre 2000-2017. Se analizó la incidencia de CB, su repercusión clínica (ingreso o tratamiento invasivo) y momento de aparición. Se consideraron dos grupos: pacientes con EG y sin EG. Se obtuvieron curvas de supervivencia y se compararon mediante log-rank test. RESULTADOS: Se realizaron 44 esplenectomías, 15 de ellas (34,1%) en pacientes con EH+EG. La edad mediana en la cirugía fue 10,3 años (rango 5,4-14,8). Veintinueve (65,9%) presentaron CB. El 50% de los pacientes con EG las presentaron antes de los 8 años vs.10,5 años en los casos sin EG (log-rank 3,9; p= 0,05). Los pacientes con EG presentaron más CB (86,7% vs. 55,2%; Chi2= 4,37, p= 0,037). En el grupo EH+EG, 8 casos (53%) necesitaron ingreso vs. 8 (31%) en el grupo sin EG (Chi2= 2, p= 0,1). El tratamiento invasivo fue necesario en 2 pacientes (13%) del grupo EH+EG y 2 pacientes (7,6%) del grupo sin EG (Chi2= 0,3, p= 0,6). CONCLUSIONES: En nuestra serie, la incidencia de CB fue superior en los pacientes con EG. Existió una tendencia a la presentación más temprana de CB en este grupo, pero ni este dato ni su repercusión clínica nos permiten recomendar la esplenectomía temprana.

An Infant With Unusually High Unconjugated Hyperbilirubinemia Due to Coexistence of Hereditary Spherocytosis and Gilbert Syndrome.

Hereditary spherocytosis is the most frequent congenital hemolytic anemia and is characterized with variable degree of anemia, jaundice, and splenomegaly. In the case of severe hyperbilirubinemia out of proportion with hemolysis, other causes of hyperbilirubinemia must be considered. Gilbert syndrome (GS) is an autosomal dominant disorder characterized with intermittent hyperbilirubinemia without any other sign and symptom of liver disease as a result of reduced activity of uridine diphosphate-glucuronyl transferase 1A1. The calculated rate of coexistence of these 2 diseases is 15 to 35/million births. Here we present a 21-month-old girl with hereditary spherocytosis diagnosed at the age of 40 days with hyperbilirubinemia out of proportion of hemolysis which led to diagnosis of GS. Thereby, the diagnosis of GS should be considered in unexplained unconjugated hyperbilirubinemia in different age groups, including infants and toddlers.
