Pregnancies in Women After Liver Transplant due to Wilson's Disease-Case Series

Wilson's disease is a rare autosomal recessive disorder. Due to a defect in membrane copper transporter, copper is not excreted in the bile and accumulates in the tissues. The only treatment for acute liver failure in Wilson's disease is a liver transplant.

AIM

Assessment of the course of pregnancies and comparison of obstetric outcomes in female liver transplant recipients in the course of Wilson's disease.

METHODOLOGY

Retrospective analysis of data of women, who were pregnant and gave birth in the years: 2017 to 2023. Evaluation of their liver function used pharmacotherapy and obstetric outcomes.

RESULTS

We recorded 11 pregnancies in liver transplantation recipients due to Wilson's disease. Ten single pregnancies and 1 twin (DCDA) were observed. In all pregnancies, graft functions and immunosuppressive drug concentrations were monitored. Three women suffered from epilepsy, one was diagnosed with psychiatric disorder. Two were diagnosed with cholestasis, and another 2 with gestational diabetes. Two of them were treated for pregnancy-induced hypertension and 2 developed preeclampsia. Deterioration of liver function parameters in pregnancy was observed in 2 cases. In total, 8 full-term babies were born and 4 late-preterm, including twins at 35 weeks of gestation. Seven pregnancies were delivered by caesarean section and 4 delivered vaginally. No complications in early postpartum period have been reported.

CONCLUSIONS

Women with Wilson's disease treated with organ transplantation have a chance of successful pregnancies and deliveries.

The volume and structural covariance network of thalamic nuclei in patients with Wilson's disease: an investigation of the association with neurological impairment

OBJECTIVE

This study aimed to examine the volumes of thalamic nuclei and the intrinsic thalamic network in patients with Wilson's disease (WDs), and to explore the correlation between these volumes and the severity of neurological symptoms.

METHODS

A total of 61 WDs and 33 healthy controls (HCs) were included in the study. The volumes of 25 bilateral thalamic nuclei were measured using structural imaging analysis with Freesurfer, and the intrinsic thalamic network was evaluated through structural covariance network (SCN) analysis.

RESULTS

The results indicated that multiple thalamic nuclei were smaller in WDs compared to HCs, including mediodorsal medial magnocellular (MDm), anterior ventral (AV), central median (CeM), centromedian (CM), lateral geniculate (LGN), limitans-suprageniculate (L-Sg), reuniens-medial ventral (MV), paracentral (Pc), parafascicular (Pf), paratenial (Pt), pulvinar anterior (PuA), pulvinar inferior (PuI), pulvinar medial (PuM), ventral anterior (VA), ventral anterior magnocellular (VAmc), ventral lateral anterior (VLa), ventral lateral posterior (VLp), ventromedial (VM), ventral posterolateral (VPL), and right middle dorsal intralaminar (MDI). The study also found a negative correlation between the UWDRS scores and the volume of the right MDm. The intrinsic thalamic network analysis showed abnormal topological properties in WDs, including increased mean local efficiency, modularity, normalized clustering coefficient, small-world index, and characteristic path length, and a corresponding decrease in mean node betweenness centrality. WDs with cerebral involvement had a lower modularity compared to HCs.

CONCLUSIONS

The findings suggest that the majority of thalamic nuclei in WDs exhibit significant volume reduction, and the atrophy of the right MDm is closely related to the severity of neurological symptoms. The intrinsic thalamic network in WDs demonstrated abnormal topological properties, indicating a close relationship with neurological impairment.

Pregnancy in Liver and Kidney Female Recipient: A Case Report

Deterioration of kidney function after orthotopic liver transplantation is a common complication that may occur after perioperative acute kidney injury (AKI) and preexisting or developing chronic kidney disease (CKD). AKI is described in the early postoperative period in more than half of recipients, whereas the main cause of CKD is pharmacotherapy. When end-stage renal failure occurs, patients may be qualified for additional transplantations. We present a rare case of a 27-year-old woman who, as a teenager, underwent 2 liver transplantations due to Wilson's disease. Surgeries were complicated by systemic infection and multiple organ failure. The kidneys did not regain their function, and therefore, after 6 months of dialysis, the organ was transplanted. Three organ transplantations were performed. Due to the patient's willingness and good graft functions, the patient started trying to conceive. Three months before successful conception, immunosuppressive therapy was changed to tacrolimus and azathioprine. Pregnancy was complicated by pregnancy-induced hypertension, and its course was closely monitored. Organ functions and immunosuppressive therapy were regularly assessed. Due to the pre-eclampsia developed in the 35th week of gestation, a Cesarean delivery was performed, and she gave birth to a daughter weighing 2350 g (Apgar 7-7-8). The patient decided to breastfeed. There were no obstetric complications or graft function deterioration in the early postpartum period. Mother and daughter left home after 7 days of hospitalization. The presented clinical situation proves that multiorgan transplantation recipients can have a successful pregnancy without impairing graft functions. Therefore, the pregnancy requires adequate preparation and increased care.

Construction of a nomogram for predicting compensated cirrhosis with Wilson's disease based on non-invasive indicators

BACKGROUND

Wilson's disease (WD) often leads to liver fibrosis and cirrhosis, and early diagnosis of WD cirrhosis is essential. Currently, there are few non-invasive prediction models for WD cirrhosis. The purpose of this study is to non-invasively predict the occurrence risk of compensated WD cirrhosis based on ultrasound imaging features and clinical characteristics.

METHODS

A retrospective analysis of the clinical characteristics and ultrasound examination data of 102 WD patients from November 2018 to November 2020 was conducted. According to the staging system for WD liver involvement, the patients were divided into a cirrhosis group (n = 43) and a non-cirrhosis group (n = 59). Multivariable logistic regression analysis was used to identify independent influencing factors for WD cirrhosis. A nomogram for predicting WD cirrhosis was constructed using R analysis software, and validation of the model's discrimination, calibration, and clinical applicability was completed. Due to the low incidence of WD and the small sample size, bootstrap internal sampling with 500 iterations was adopted for validation to prevent overfitting of the model.

RESULTS

Acoustic Radiation Force Impulse (ARFI), portal vein diameter (PVD), and serum albumin (ALB) are independent factors affecting WD cirrhosis. A nomogram for WD cirrhosis was constructed based on these factors. The area under the ROC curve (AUC) of the model's predictive ability is 0.927 (95% CI: 0.88-0.978). As demonstrated by 500 Bootstrap internal sampling validations, the model has high discrimination and calibration. Clinical decision curve analysis shows that the model has high clinical practical value. ROC curve analysis of the model's rationality indicates that the model's AUC is greater than the AUC of using ALB, ARFI, and PVD alone.

CONCLUSION

The nomogram model constructed based on ARFI, PVD, and ALB can serve as a non-invasive tool to effectively predict the risk of developing WD cirrhosis.

Taste and smell function in Wilson's disease

OBJECTIVE

Wilson's disease (WD) is a metabolic disorder associated with abnormal copper metabolism that results in hepatic, psychiatric, and neurologic symptoms. No investigation of taste function has been made in patients with WD, although olfactory dysfunction has been evaluated.

METHODS

Quantitative taste and smell test scores of 29 WD patients were compared to those of 790 healthy controls. Taste was measured using the 53-item Waterless Empirical Taste Test (WETT®) and smell using the 40-item revised University of Pennsylvania Smell Identification Test (R-UPSIT®). Multiple linear regression analysis controlled for age and sex.

RESULTS

Average WETT® scores did not differ meaningfully between WD and control subjects (respective medians & IQRs = 32 [28-42] & 34 [27-41]); linear regression coefficient = 1.19, 95% CI [-0.81, 3.19], p = 0.242). In contrast, WD was associated with significantly reduced olfactory function [respective median (IQR) R-UPSIT® scores = 35 (33-37) vs. 37 (35-38); adjusted linear regression coefficient = -1.59, 95% CI [-2.34, -0.833]; p < 0.001)]. Neither olfaction nor taste were influenced by WD symptom subtype [23 (79.3%) were hepatic-predominant; 6 (20.7%) neurologic predominant]; R-UPSIT®, p = 0.774; WETT®, p = 0.912). No effects of primary medication or years since diagnosis (R-UPSIT®, p = 0.147; WETT®, p = 0.935) were found. Weak correlations were present between R-UPSIT® and WETT® scores for both control (r=0.187, p < 0.0001) and WD (r=0.237) subjects, although the latter correlation did not reach the 0.05 α level (p = 0.084).

CONCLUSION

Although WD negatively impacts smell function, taste is spared. Research is needed to understand the pathophysiologic mechanisms responsible for this divergence.

Systemic lupus erythematosus combined with Wilson's disease: a case report and literature review

BACKGROUND

Systemic lupus erythematosus (SLE) and Wilson's disease (WD) are both systemic diseases that can affect multiple organs in the body. The coexistence of SLE and WD is rarely encountered in clinical practice, making it challenging to diagnose.

CASE REPORT

We present the case of a 9-year-old girl who initially presented with proteinuria, haematuria, pancytopenia, hypocomplementemia, and positivity for multiple autoantibodies. She was diagnosed with SLE, and her blood biochemistry showed elevated liver enzymes at the time of diagnosis. Despite effective control of her symptoms, her liver enzymes remained elevated during regular follow-up. Laboratory tests revealed decreased serum copper and ceruloplasmin levels, along with elevated urinary copper. Liver biopsy revealed chronic active hepatitis, moderate inflammation, moderate-severe fibrosis, and a trend towards local cirrhosis. Genetic sequencing revealed compound heterozygous mutations in the ATP7B gene, confirming the diagnosis of SLE with WD. The girl received treatment with a high-zinc/low-copper diet, but her liver function did not improve. Upon recommendation following multidisciplinary consultation, she underwent liver transplantation. Unfortunately, she passed away on the fourth day after the surgery.

CONCLUSIONS

SLE and WD are diseases that involve multiple systems and organs in the body, and SLE complicated with WD is rarely encountered in the clinic; therefore, it is easy to misdiagnose. Because penicillamine can induce lupus, it is not recommended. Liver transplantation is indicated for patients with liver disease who do not respond to medical treatment with WD. However, further research is needed to determine the optimal timing of liver transplantation for patients with SLE complicated with WD.

Clinical profile of adult and pediatric patients with hepatic Wilson's disease

BACKGROUND

The clinical profile varies in patients with Wilson's disease (WD). There is paucity of data regarding adult and pediatric patients with hepatic WD.

METHODS

As many as 140 consecutive patients diagnosed with hepatic WD between December 2006 and January 2021 were included in the study. Data was collected regarding the demographic parameters, clinical presentation, extrahepatic organ involvement, liver histology and laboratory investigations. Adult and children (0-14 years) with hepatic WD were compared regarding these features.

RESULT

Eighty-eight adults and 52 children were included in the study. The median age of presentation was 17 years (range: 1.1-42 years). Male preponderance was seen (adult 68/88, 69%; children 40/52, 77%). Adults as compared to children presented more commonly as cirrhosis (52/88 vs. 15/52, p = 0.0005) and with hepatic decompensation (35/88 vs. 9/52, p = 0.005). Presentation with acute-on-chronic liver failure (ACLF) was more common in children (10/52 vs. 2/88, p = 0.0005). Twenty-eight-day mortality was 50% (5/10) in children and none in adults presenting with ACLF. Nazer's Prognostic Index (≥ 7) and New Wilson Index were more accurate in predicting mortality among children with ACLF with AUROC 1, while AARC (APASL ACLF Research Consortium) was less accurate with AUROC 0.45. Liver histology findings were similar in adults and children. Extrahepatic involvement was also similar. (8/88 in adults vs. 3/52 children, p value 0.48).

CONCLUSION

Most patients with WD present as cirrhosis in adulthood. ACLF is more common in children. Nazer's prognostic index and new Wilson Index score are accurate in predicting mortality in children with ACLF.

Changing etiological spectrum of acute liver failure

BACKGROUND AND OBJECTIVES

Acute liver failure (ALF) is an uncommon but potentially dramatic syndrome characterized by massive hepatic necrosis and has a very high mortality rate of 50% to 75% without liver transplantation. This study is aimed at analyzing the etiological spectrum of ALF patients and compare these with ALF mimics such as malaria, dengue fever and other tropical infectious diseases.

METHODS

The study population included patients who presented with ALF and ALF mimics in a tertiary care center over two years. We retrospectively analyzed the patient case files and a comparison was made concerning the baseline demographic details, clinical profile, laboratory values and outcomes.

RESULTS

Sixty-three patients were assessed, with 32 in ALF and 31 in ALF mimics group. The most common cause for ALF was hepatitis A virus (25%), followed by hepatitis B virus (18.7%), drug-induced liver injury (12.7%), autoimmune hepatitis (12.5%), hepatitis E virus (9.3%) and Wilson's disease (6.25%). In the ALF mimics group, malaria (58.06%) was the most common cause, followed by dengue fever (16.1%), leptospirosis (12.9%) and scrub typhus (12.9%). Patients in the ALF mimics group had significantly higher incidence of fever (p = 0.001), hepatosplenomegaly (p = 0.01), anemia (p = 0.02) and shorter jaundice to encephalopathy duration (p = 0.032) as compared to the ALF group, while higher transaminase levels (p = 0.03), bilirubin (p = 0.01), prothrombin time (p = 0.01), serum ammonia (p = 0.02) and mortality (p = 0.02) were observed in ALF patients.

CONCLUSIONS

The most common cause for ALF was hepatitis A virus, followed by hepatitis B virus, while in ALF mimics it was malaria followed by dengue fever, in our study. Patients of ALF mimics can have similar presentation, but a high index of suspicion and awareness is required to identify the common infectious ALF mimics for early diagnosis.

Renal Cell Carcinoma and Hepatocellular Carcinoma in a Patient with Wilson's Disease

No reports of renal cancer in patients with Wilson's disease (WD) exist. We herein report a 37-year-old Japanese man diagnosed with WD who had been treated with d-penicillamine 9 years prior. Hepatocellular carcinoma had been diagnosed at 36 years old and treated with radiofrequency ablation therapy. One year later, renal cancer and recurrent hepatocellular carcinoma had developed. The hepatocellular carcinoma was treated after renal cancer surgical resection of a clear-cell-type renal cell carcinoma, with iron, rather than copper, deposited on the renal cancer cells. This patient harbored a novel mutation, p. Leu1395Terfs in ATP7B.

Distal renal tubular acidosis as presenting manifestation of Wilson disease in a 11-year-old girl

A 11-year-old girl was referred to the pediatric nephrology services of our hospital for evaluation of vitamin-D-refractory rickets. She was born to second-degree consanguineous parents. On examination, she had wrist widening and bilateral genu varum. She had normal anion gap metabolic acidosis, hypokalemia, and hyperchloremia. The fractional excretion of bicarbonate was 3% and the urine anion gap was positive. She also had hypercalciuria, but no phosphaturia, glucosuria or aminoaciduria. In view of a family history of an elder sister having rigidity with cognitive and speech impairment, an ophthalmic evaluation by slit lamp examination was performed in the index case that revealed bilateral Kayser-Fleischer rings. Serum ceruloplasmin was low and 24-h urine copper was elevated in the index case. Whole exome sequencing unveiled a novel pathogenic variant in exon 2 of the ATP7B gene (chr13: c.470del; Depth: 142x) (homozygous) that resulted in a frameshift and premature truncation of the protein, 15 amino acids downstream to codon 157 (p. Cys157LeufsTer15; NM_000053.4) confirming Wilson disease. There were no mutations in the ATP6V0A4, ATP6V1B1, SLC4A1, FOXI1, WDR72 genes or other genes that are known to cause distal RTA. Therapy with D-penicillamine and zinc supplements was initiated. A low dose of 2.5 mEq/kg/day of potassium citrate supplementation normalized the serum bicarbonate levels. This case was notable for the absence of hepatic or neurological involvement at admission. Wilson disease is well known to cause proximal renal tubular acidosis and Fanconi syndrome, with relatively lesser involvement of the distal renal tubules in the literature. However, isolated distal renal tubular involvement as presenting manifestation of Wilson disease (without hepatic or neurological involvement) is rare and can lead to diagnostic confusion.

Assessment of sleep disturbance in patients with Wilson's disease

BACKGROUND

Wilson's disease (WD) is frequently manifested with anxiety, depression and sleep disturbance; this investigation aimed to elucidate these manifestations and identify the influencing factors of sleep disturbance.

METHODS

Sleep disturbance, anxiety and depression were compared in 42 WD and 40 age- and gender-matched healthy individuals. 27 individuals indicated a neurological form of the disease (NV), and 15 had a non-neurological variant (NNV).

RESULTS

This investigation revealed that the Parkinson's disease sleep scale (PDSS) score of WD individuals was lower, whereas their Epworth Sleepiness Scale (ESS), Pittsburgh sleep quality index (PSQI), Hamilton Anxiety Scale (HAMA), and Hamilton Depression Scale (HAMD) scores were higher than the healthy individuals (p < 0.05). Furthermore, the WD subjects had markedly increased prevalence of poor sleep quality, anxiety, and depression than healthy individuals (p < 0.05). Subgroup analysis showed that NV subjects had significantly higher scores on the UWDRS, PSQI, HAMA, and HAMD scales than those in the NV group, as well as higher rates of EDS, anxiety, and depression (p < 0.05). In patients with sleep disturbance, we identified UWDRS, neurological variant, and depression as associated factors. The linear regression model demonstrated depression as the dominant risk factor.

CONCLUSIONS

Depression is highly correlated with and is a determinant of sleep disturbance in WD patients.

Bilateral optic atrophy in Wilson disease: A case report and literature review

Wilson disease (WD) is an autosomal recessive disorder of copper metabolism. The clinical manifestations of WD are complex and variable, with Kayser-Fleischer ring (K-F ring) and the sunflower cataract being the most common ocular findings. Visual impairment is rare in patients with WD. We report the case of a 17-year-old female with bilateral optic atrophy associated with WD and summarize the clinical features of previously reported cases of optic neuropathy in WD, Clinicians should be aware that WD is a rare cause of optic neuropathy and that optic neuropathy in patients with WD may need to be recognized and screened.

Neurological complications due to copper deficiency in the context of Wilson disease treatment: a case report with long-term follow-up and review of the literature

The objective is to investigate the presentation, complications, management, and outcomes of copper deficiency-induced neurological pathologies due to Wilson disease (WD) overtreatment. We examined the case of a WD patient who developed a low thoracic dorsal myelopathy due to chronic hypocupremia from excessive zinc therapy. A comprehensive literature review was conducted to identify similar cases. Ten additional cases of neurological pathology resulting from copper deficiency in the context of WD over-treatment were identified, all occurring during therapy with zinc salts. Myelopathy and peripheral neuropathy were the most common complications, while two additional groups reported leukoencephalopathy. Early cytopenia was often associated with copper deficiency-related neurological pathology appearing early in the context of copper deficiency. WD patients undergoing treatment, especially with zinc salts, should be closely monitored to prevent over-treatment and the consequent copper deficiency. Regular complete blood counts could provide early detection of copper deficiency, avoiding irreversible neurological damage. Swift recognition of new neurological signs not consistent with WD and timely discontinuation of the decoppering therapy are critical for improving outcomes. The optimal management, including the potential benefit of copper supplementation in patients with WD and subsequent therapy adjustments, remains unclear and necessitates further investigation. Despite the general poor functional neurological outcomes, there were some exceptions that warrant further exploration.

Teaching NeuroImage: Neuroimaging Features of Wilson Disease

A 13-year-old boy of nonconsanguineous parents presented with abnormal body movements, gait difficulty, and slurring of speech for 2 years. On examination, he had rigidity, dystonia, dysarthria, and drooling. Ophthalmologic examination revealed bilateral Kayser-Fleischer rings. He had elevated serum "free" copper levels (41.2 μg/dL [range:10-15]), 24-hour urine copper levels (895.7 μg/d [range:<60]), and reduced serum ceruloplasmin levels (4.3 mg/dL (range:20-40]). MRI revealed "face of giant panda" appearance (Figure A), T2-fluid attenuated inversion recovery hyperintensities (Figure, B and C), and frontal cystic encephalomalacic changes (Figure D), suggestive of Wilson disease (WD). Face of giant panda in WD, first described by Hitoshi et al.,1 is due to high signal intensity in tegmentum with normal signals in red nuclei forming the eyes, normal signals of pars reticulata (lateral portion) of substantia nigra forming the ears, and hypointensity of superior colliculus forming the chin.2 Bilateral cystic changes are less commonly reported in WD.3 Recognizing diverse neuroimaging signatures beyond well-known findings in WD enhances diagnostic accuracy.

A rare presentation of Wilson disease with neurological symptoms: Case report and genetic analysis

RATIONALE

Wilson disease is a rare genetic disorder primarily associated with hepatic symptoms; however, its unique neurological presentation remains a subject of interest in the medical literature. This case report contributes to existing knowledge by highlighting the unusual manifestation of Wilson disease with significant neurological symptoms.

PATIENT CONCERNS

The patient, pseudonym John Smith, presented with prominent neurological symptoms, including tremors, dystonia, and psychiatric manifestations. Clinical findings corroborated copper accumulation in the brain, prompting a thorough diagnostic investigation.

DIAGNOSES

Genetic analysis revealed two ATP7B mutations, confirming the primary diagnosis of Wilson disease. This case underscores the importance of recognizing atypical neurological presentations in the context of this rare genetic disorder.

INTERVENTIONS

Chelation therapy, initiated promptly upon diagnosis, targeted copper overload. The intervention led to notable improvements in neurological symptoms and psychiatric manifestations. The dosage and duration of treatment were adjusted based on regular monitoring.

OUTCOMES

Regular follow-up revealed a positive trajectory, with reduced tremors and improved overall well-being. Genetic testing, coupled with clinical assessments, contributed to monitoring treatment efficacy and optimizing therapeutic interventions.

LESSONS

The main takeaway lessons from this case include the significance of a comprehensive diagnostic approach, personalized therapeutic interventions, and the imperative to acknowledge the diverse clinical spectrum of Wilson disease. Early recognition and tailored treatment contribute to favorable outcomes in cases with atypical neurological presentations.

Intrahepatic Cholangiocarcinoma in Wilson's Disease: A Case Report

BACKGROUND Wilson's disease is a rare autosomal recessive disorder characterized by excessive accumulation of copper in the liver, brain, and kidneys. Although it affects only approximately 1 in 30 000 individuals, it leads to progressive liver damage and neurological issue. Wilson's disease presents a wide spectrum of clinical manifestations related to hepatic disease, ranging from asymptomatic cases to acute liver failure. The occurrence of hepatobiliary malignancies, including intrahepatic cholangiocarcinoma, is relatively uncommon in Wilson's disease, even among patients with cirrhosis. Only 14 cases have been published so far, including the present report, and its etiology remains unclear. CASE REPORT We report the successful treatment of intrahepatic cholangiocarcinoma in a 39-year-old woman with Wilson's disease. Twenty-two years after being diagnosed with Wilson's disease, intrahepatic cholangiocarcinoma was diagnosed. She had an intrahepatic mass that was found to be a 4.3-cm ill-defined hypodense lesion in liver segment 3/4, with features suggesting infiltrative intrahepatic cholangiocarcinoma rather than hepatocellular carcinoma. Laboratory results showed slightly elevated liver enzymes and tumor markers. There was no evidence of metastasis on chest computed tomography or positron emission tomography, and the tumor was resectable, so surgery was the first-choice treatment option. Left hepatectomy was performed successfully, and the final pathology confirmed adenocarcinoma with clear resection margins. The patient received adjuvant chemotherapy with capecitabine. To date, the patient has been doing well without evidence of recurrence or metastasis. CONCLUSIONS Despite limited knowledge regarding hepatic malignancy in Wilson's disease, it is crucial to prioritize careful monitoring and develop suitable treatment strategies upon diagnosis to achieve favorable outcomes, considering the potential occurrence of intrahepatic cholangiocarcinoma in Wilson's disease.

A case of Wilson's disease combined with intracranial lipoma and dysplasia of the corpus callosum with review of the literature

BACKGROUND

Wilson's disease (WD) is an inherited disorder of copper metabolism. Agenesis of the corpus callosum is the complete or partial absence of the major united fiber bundles connecting the cerebral hemispheres. Intracranial lipoma is an adipose tissue tumor resulting from an abnormal embryonic development of the central nervous system. The simultaneous occurrence of these three disorders is rare and has not been reported. This report focuses on the pathogenesis and association between the three disorders and highlights the importance of recognizing and effectively managing their coexistence.

CASE PRESENTATION

The purpose of this study was to present a patient with coexisting WD, intracranial lipoma, and corpus callosum dysplasia. We reviewed a female patient hospitalized in 2023 with clinical manifestations of elevated aminotransferases and decreased ceruloplasmin, as well as genetic testing for an initial diagnosis of Wilson's disease. Subsequently, a cranial MRI showed corpus callosum dysplasia with short T1 signal changes in the cerebral falx, leading to a final diagnosis of Wilson's disease combined with intracranial lipoma and corpus callosum dysplasia. The patient's WD is currently stable after treatment with sodium dimercaptosulfonamide (DMPS) and penicillamine, and the patient's abnormal copper metabolism may promote the growth of intracranial lipoma.

CONCLUSION

The pathogenesis of WD combined with intracranial lipoma and corpus callosum dysplasia is complex and clinically rare. The growth of intracranial lipomas may be associated with abnormal copper metabolism in WD. Abnormal copper metabolism affects lipid metabolism and triggers inflammatory responses. Therefore, early diagnosis and treatment are beneficial for improvement. Each new case of this rare co-morbidity is important as it allows for a better assessment and understanding of these cases' more characteristic clinical manifestations, which can help estimate the course of the disease and possible therapeutic options.

Late-onset Wilson Disease in a Patient Followed-up for Nonalcoholic Fatty Liver Disease

A 73-year-old woman was referred to our hospital for persistent liver dysfunction. When the patient was 45 years old, her youngest sister had been diagnosed with Wilson disease (WD). The patient therefore underwent several family screening tests, all of which were unremarkable. She had an annual medical checkup and was diagnosed with liver dysfunction and fatty liver at 68 years old. A liver biopsy and genetic testing were performed, and she was diagnosed with WD; chelation therapy was then initiated. In patients with hepatic disorders and a family history of WD, multiple medical examinations should be conducted, as the development of WD is possible regardless of age.

Changes in Hepatic Function After Splenectomy for Hepatolenticular Degeneration, Cirrhosis, and Hypersplenism

BACKGROUND

Patients with hepatic reticulum degeneration (HLD) may eventually develop complications of cirrhosis with splenomegaly and hypersplenism, requiring splenectomy to alleviate hypersplenism and complete lifelong copper therapy. The purpose of this study is to investigate the effect of splenectomy on liver function in patients with hypersplenism.

METHODS

A retrospective systematic analysis was conducted on the liver function indicators of 220 HLD patients who underwent splenectomy from January 2015 to January 2018 before surgery and on days 1, 3, 5, 7, and 14 after surgery. Among them, 30 patients were followed up for 6 months.

RESULTS

The Child score increased on the 1st day after surgery and gradually decreased after the 1st day. The level of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TB) increased 5 days after surgery (P < .01) and decreased on the 14th day after surgery (P < .01); the level of albumin (ALB) decreased on the 1st, 3rd, and 5th day after surgery (P < .01) and increased on the 14th day (P < .01). The follow-up results of the patient for 6 months showed that the levels of ALT and AST decreased, while the levels of ALB increased 6 months after surgery.

CONCLUSION

Splenectomy is proved to be beneficial for the improvement of liver function in HLD patients combined with hypersplenism, which realize a lifelong anti-copper treatment.
