Vertebral metastasis of hepatocellular carcinoma secondary to viral hepatitis B: case report of 2 patients.

Bone metastases from liver cancer are rare. We report two cases of bone metastases revealing HBV-induced HCC. A 26-year-old african man presented with 4 months of low back pain in the context of general deterioration. Examination revealed a lumbar spinal syndrome and hepatomegaly. Abdominal ultrasound revealed a multinodular liver, and a CT scan of the spine revealed osteolytic lesions. Biological tests revealed a hepatic cytolysis syndrome, hepatic cholestasis and hepatocellular insufficiency. Alpha foetoprotein levels were elevated and hepatitis B serology was positive. We adopted the diagnosis of HCC of viral B origin with bone metastasis. The second case involved a 44-year-old African man admitted for 10 days with back pain. Examination revealed a spinal syndrome, paraplegia and hepatomegaly. A thoracic-abdominal-pelvic CT scan revealed typical HCC lesions and osteolytic lesions on the ribs, pelvis and vertebrae. The biology revealed a biological inflammatory syndrome, hepatic cytolysis, a hepatocellular insufficiency syndrome and a cholestasis syndrome. Alfa-feto proteins were elevated and HBV serology was positive. The diagnosis of bone metastasis of HCC secondary to HBV infection was accepted.

Noninvasive prediction of insufficient biochemical response after ursodeoxycholic acid treatment in patients with primary biliary cholangitis based on pretreatment nonenhanced MRI.

OBJECTIVES: To explore the feasibility of pretreatment nonenhanced magnetic resonance imaging (MRI) in predicting insufficient biochemical response to ursodeoxycholic acid (UDCA) in patients with primary biliary cholangitis (PBC). METHODS: From January 2009 to April 2022, consecutive PBC patients who were treated with UDCA and underwent nonenhanced MRI within 30 days before treatment were retrospectively enrolled. All MR images were independently evaluated by two blinded radiologists. Uni- and multivariable logistic regression analyses were performed to develop a predictive model for 12-month insufficient biochemical response. Model performances were evaluated by computing the area under the receiver operating characteristic curve (AUC), sensitivity, and specificity. RESULTS: A total of 74 patients (50.6 ± 11.9 years; 62 females) were included. Three pretreatment MRI features, including hepatomegaly (odds ratio [OR]: 4.580; p = 0.011), periportal hyperintensity on T2-weighted imaging (T2WI) (OR: 4.795, p = 0.008), and narrowing of the bile ducts (OR: 3.491; p = 0.027) were associated with 12-month insufficient biochemical response in the multivariable analysis. A predictive model based on the above indicators had an AUC of 0.781, sensitivity of 85.4%, and specificity of 61.5% for predicting insufficient biochemical response. CONCLUSIONS: A noninvasive model based on three pretreatment MRI features could accurately predict 12-month insufficient biochemical response to UDCA in patients with PBC. Early identification of PBC patients at increased risk for insufficient response can facilitate the timely initiation of additional treatment. CLINICAL RELEVANCE STATEMENT: A noninvasive predictive model constructed by incorporating three pretreatment MRI features may help identify patients with primary biliary cholangitis at high risk of insufficient biochemical response to ursodeoxycholic acid and facilitate the timely initiation of additional treatment. KEY POINTS: • Noninvasive imaging features based on nonenhanced pretreatment MRI may predict an insufficient biochemical response to UDCA in PBC patients. • A combined model based on three MRI features (hepatomegaly, periportal hyperintensity on T2-weighted imaging, and narrowing of the bile ducts) further improved the predictive efficacy for an insufficient biochemical response to UDCA in PBC patients, with high sensitivity and specificity. • The nomogram of the combined model showed good calibration and predictive efficacy for an insufficient biochemical response to UDCA in PBC patients. In particular, the calibration curve visualised the clinical applicability of the prediction model.

[Analysis of 9 cases of drug induced hypersensitivity syndrome related hemophagocytic lymphohistiocytosis].

Objective: To analyze the clinical features,treatment and prognosis of drug induced hypersensitivity syndrome related hemophagocytic lymphohistiocytosis (DIHS-HLH). Methods: This was a retrospective case study. Clinical characteristics, laboratory results, treatment and prognosis of 9 patients diagnosed with DIHS-HLH in Beijing Children's hospital between January 2020 and December 2022 were summarized. Kaplan-Meier survival analysis was used to calculate the overall survival rate. Results: Among all 9 cases, there were 6 males and 3 females, with the age ranged from 0.8 to 3.1 years. All patients had fever, rash, hepatomegaly and multiple lymph node enlargement. Other manifestations included splenomegaly (4 cases), pulmonary imaging abnormalities (6 cases), central nervous system symptoms (3 cases), and watery diarrhea (3 cases). Most patients showed high levels of soluble-CD25 (8 cases), hepatic dysfunction (7 cases) and hyperferritinemia (7 cases). Other laboratory abnormalities included hemophagocytosis in bone marrow (5 cases), hypofibrinogenemia (3 cases) and hypertriglyceridemia (2 cases). Ascending levels of interleukin (IL) 5, IL-8 and interferon-γ (IFN-γ) were detected in more than 6 patients. All patients received high dose intravenous immunoglobulin, corticosteroid and ruxolitinib, among which 4 patients were also treated with high dose methylprednisolone, 2 patients with etoposide and 2 patients with cyclosporin A. After following up for 0.2-38.6 months, 7 patients survived, and the 1-year overall survival rate was (78±14)%. Two patients who had no response to high dose immunoglobulin, methylprednisolone 2 mg/(kg·d) and ruxolitinib died. Watery diarrhea, increased levels of IL-5 and IL-8 and decreased IgM were more frequently in patients who did not survive. Conclusions: For children with fever, rash and a suspicious medication history, when complicated with hepatomegaly, impaired liver function and high levels of IL-5 and IL-8, DIHS-HLH should be considered. Once diagnosed with DIHS-HLH, suspicious drugs should be stopped immediately, and high dose intravenous immunoglobulin, corticosteroid and ruxolitinib could be used to control disease.

Clinical and laboratory features associated with macrophage activation syndrome in Still's disease: data from the international AIDA Network Still's Disease Registry.

To characterize clinical and laboratory signs of patients with Still's disease experiencing macrophage activation syndrome (MAS) and identify factors associated with MAS development. Patients with Still's disease classified according to internationally accepted criteria were enrolled in the AutoInflammatory Disease Alliance (AIDA) Still's Disease Registry. Clinical and laboratory features observed during the inflammatory attack complicated by MAS were included in univariate and multivariate logistic regression analysis to identify factors associated to MAS development. A total of 414 patients with Still's disease were included; 39 (9.4%) of them developed MAS during clinical history. At univariate analyses, the following variables were significantly associated with MAS: classification of arthritis based on the number of joints involved (p = 0.003), liver involvement (p = 0.04), hepatomegaly (p = 0.02), hepatic failure (p = 0.01), axillary lymphadenopathy (p = 0.04), pneumonia (p = 0.03), acute respiratory distress syndrome (p < 0.001), platelet abnormalities (p < 0.001), high serum ferritin levels (p = 0.009), abnormal liver function tests (p = 0.009), hypoalbuminemia (p = 0.002), increased LDH (p = 0.001), and LDH serum levels (p < 0.001). At multivariate analysis, hepatomegaly (OR 8.7, 95% CI 1.9-52.6, p = 0.007) and monoarthritis (OR 15.8, 95% CI 2.9-97.1, p = 0.001), were directly associated with MAS, while the decade of life at Still's disease onset (OR 0.6, 95% CI 0.4-0.9, p = 0.045), a normal platelet count (OR 0.1, 95% CI 0.01-0.8, p = 0.034) or thrombocytosis (OR 0.01, 95% CI 0.0-0.2, p = 0.008) resulted to be protective. Clinical and laboratory factors associated with MAS development have been identified in a large cohort of patients based on real-life data.

Active-phase Plasma Alkaline Phosphatase Isozyme Activity Is a Sensitive Biomarker for Excessive Fructose Intake.

BACKGROUND/AIM: Excessive fructose intake reportedly leads to the development of nonalcoholic fatty liver disease (NAFLD). In our previous study, we reported that plasma activities of alkaline phosphatase (ALP) isozymes were markedly changed in rats with excessive fructose intake-induced hepatomegaly. In this study, we examined ALP isozyme activity prior to the occurrence of hepatomegaly, and investigated the effect of the timing of sample collection, to explore its potential as a biomarker. MATERIALS AND METHODS: After 1-week intake of a 63% high-fructose diet (HFrD), blood samples were collected from male rats during sleep or active phases to analyze biochemical parameters. RESULTS: Body and liver weights were similar between the HFrD and control diet groups, indicating that hepatomegaly due to excessive fructose intake had not occurred. The triglyceride levels and glutamate dehydrogenase (GLDH) activity were significantly elevated to similar degrees at both time points. HFrD intake significantly increased liver-type ALP (L-ALP) activity, stimulating it by 12.7% at the sleep phase and by 124.3% at the active phase. HFrD consumption also significantly decreased intestinal-type ALP (I-ALP) at the active phase, but only showed a decreasing trend during the sleep phase. CONCLUSION: Measurements of plasma ALP isozyme and GLDH activity, and triglyceride levels are effective early biomarkers of impending NAFLD caused by excessive fructose intake. L-ALP and I-ALP activities during the active phase are particularly sensitive for detection of excessive fructose intake before the occurrence of NAFLD.

Virome Profiling of Chickens with Hepatomegaly Rupture Syndrome Reveals Coinfection of Multiple Viruses.

Liver diseases seriously challenge the health of chickens raised on scaled farms and cause tremendous economic losses to farm owners. The causative agents for liver diseases are still elusive, even though various pathogens, such as the hepatitis E virus, have been reported. In the winter of 2021, a liver disease was observed on a chicken farm in Dalian, China, which increased chicken mortality by up to 18%. We conducted panvirome profiling of the livers, spleens, kidneys, and recta of 20 diseased chickens. The viromic results revealed coinfection of multiple viruses, including pathogenic ones, in these organs. The viruses were highly identical to those detected in other provinces, and the vaccine and field strains of avian encephalomyelitis virus (AEV) and chicken infectious anemia virus (CIAV) cocirculated on the farm. In particular, the liver showed higher abundance of AEV and multiple fowl adenoviruses than other organs. Furthermore, the liver also contracted avian leukemia virus and CIAV. Experimental animals with infected liver samples developed minor to medium lesions of the liver and showed a virus abundance profile for AEV across internal organs similar to that in the original samples. These results suggest that coinfection with multiple pathogenic viruses influences the occurrence and development of infectious liver disease. The results also highlight that strong farm management standards with strict biosafety measures are needed to minimize the risk of pathogenic virus introduction to the farm.

Fructose-1,6-bisphosphatase is a nonenzymatic safety valve that curtails AKT activation to prevent insulin hyperresponsiveness.

Insulin inhibits gluconeogenesis and stimulates glucose conversion to glycogen and lipids. How these activities are coordinated to prevent hypoglycemia and hepatosteatosis is unclear. Fructose-1,6-bisphosphatase (FBP1) is rate controlling for gluconeogenesis. However, inborn human FBP1 deficiency does not cause hypoglycemia unless accompanied by fasting or starvation, which also trigger paradoxical hepatomegaly, hepatosteatosis, and hyperlipidemia. Hepatocyte FBP1-ablated mice exhibit identical fasting-conditional pathologies along with AKT hyperactivation, whose inhibition reversed hepatomegaly, hepatosteatosis, and hyperlipidemia but not hypoglycemia. Surprisingly, fasting-mediated AKT hyperactivation is insulin dependent. Independently of its catalytic activity, FBP1 prevents insulin hyperresponsiveness by forming a stable complex with AKT, PP2A-C, and aldolase B (ALDOB), which specifically accelerates AKT dephosphorylation. Enhanced by fasting and weakened by elevated insulin, FBP1:PP2A-C:ALDOB:AKT complex formation, which is disrupted by human FBP1 deficiency mutations or a C-terminal FBP1 truncation, prevents insulin-triggered liver pathologies and maintains lipid and glucose homeostasis. Conversely, an FBP1-derived complex disrupting peptide reverses diet-induced insulin resistance.

Glycogenic hepatopathy is associated with type 1 diabetes mellitus in only a minority of cases in a contemporary adult population.

OBJECTIVES: This study examines the clinical-pathological profiles of patients with glycogenic hepatopathy in a contemporary cohort of patients at an adult acute care hospital. METHODS: Liver biopsies with glycogenic hepatopathy were retrieved from the departmental surgical pathology database, the histological findings were studied, and the clinical findings were reviewed. RESULTS: Five cases of glycogenic hepatopathy were found, including cases associated with type 1 diabetes mellitus (n = 1), type 2 diabetes mellitus (n = 1), corticosteroids (n = 2), and anorexia (n = 2, including the patient with type 1 diabetes). AST and ALT were normal to mildly elevated (13-115 U/L and 7-126 U/L, respectively). Trace ascites was present in two patients. Hepatomegaly was only present in the patient with type 1 diabetes at the time of diagnosis. CONCLUSIONS: Four of five cases were associated with etiologies other than type 1 diabetes, which is widely reported as the most common etiology of glycogenic hepatopathy. This study suggests that etiologies currently only rarely recognized may actually be more common causes of glycogenic hepatopathy than type 1 diabetes in a contemporary adult population. It is important not only to recognize that these rarely reported causes of glycogenic hepatopathy may be underrecognized, but that the clinical presentation may also be mild.

Hepatic amyloidosis: a prevalence study and clinical characterization of a rare and severe disease.

BACKGROUND AND AIM: Amyloidosis is a systemic disease characterized by extracellular deposition of amyloid protein, most commonly in the heart and kidney. Hepatic amyloidosis is a rare form of presentation that ranges from mild hepatomegaly and altered liver biochemical tests to acute liver failure. The aims of this study were to evaluate the prevalence of amyloidosis in patients undergoing liver biopsy and describe its main clinical characteristics and prognostic impact. METHODS: A retrospective analysis of all patients with a histological diagnosis of hepatic amyloidosis between January 2010 and December 2019 was performed. MAJOR RESULTS: A total of 7 patients were identified from a total of 1773 liver biopsy procedures (0.4%), with a female predominance (6/7) and median age of diagnosis of 62 years. The most common clinical manifestations included hepatomegaly (4/7), jaundice (2/7) and peripheral edema (2/7), whereas 3/7 patients were asymptomatic. Every patient presented abnormalities in liver biochemical tests, more commonly cholestasis (6/7), but also cytolysis (4/7) or hyperbilirubinemia (2/7). Abnormal imaging findings included hepatomegaly, steatosis or parenchymal heterogeneity. In most patients (5/7), other organs were involved, most commonly with nephrotic syndrome (3/7) and infiltrative cardiomyopathy (3/7). The most common type was AA amyloidosis (3/7) followed by AL amyloidosis (2/7). The 1-year mortality rate was 43% and the median survival was 24 months. CONCLUSIONS: We report a low prevalence (0.4%) of amyloidosis among patients undergoing liver biopsy. Although rare, hepatic amyloidosis is associated with a dismal prognosis and a high index of suspicion is crucial to achieve an early diagnosis. .

Right ventricular failure in left heart disease: from pathophysiology to clinical manifestations and prognosis.

Right heart failure (RHF) is a clinical syndrome in which symptoms and signs are caused by dysfunction and/or overload of the right heart structures, predominantly the right ventricle (RV), resulting in systemic venous hypertension, peripheral oedema and finally, the impaired ability of the right heart to provide tissue perfusion. Pathogenesis of RHF includes the incompetence of the right heart to maintain systemic venous pressure sufficiently low to guarantee an optimal venous return and to preserve renal function. Virtually, all myocardial diseases involving the left heart may be responsible for RHF. This may result from coronary artery disease, hypertension, valvular heart disease, cardiomyopathies and myocarditis. The most prominent clinical signs of RHF comprise swelling of the neck veins with an elevation of jugular venous pressure and ankle oedema. As the situation worsens, fluid accumulation becomes generalised with extensive oedema of the legs, congestive hepatomegaly and eventually ascites. Diagnosis of RHF requires the presence of signs of elevated right atrial and venous pressures, including dilation of neck veins, with at least one of the following criteria: (1) compromised RV function; (2) pulmonary hypertension; (3) peripheral oedema and congestive hepatomegaly. Early recognition of RHF and identifying the underlying aetiology as well as triggering factors are crucial to treating patients and possibly reversing the clinical manifestations effectively and improving prognosis.

Impact of Preoperative Protein Sparing Modified Fast Diet on Bariatric Surgery.

INTRODUCTION: Bariatric surgery can become technically challenging in the setting of liver steatosis and hepatomegaly. The protein sparing modified fast (PSMF) diet helps in achieving rapid weight loss. The aim of this study is to explore the results of a preoperative PSMF diet on liver volume and steatosis as well as on intraoperative and postoperative complications in patients with hepatomegaly undergoing Roux-en-Y gastric bypass (RYGB). METHODS: Between January 2010 and January 2021, 713 patients undergoing RYGB as a primary bariatric surgery were divided in two groups. Those with a measured liver length above 16 cm and or evidence of liver steatosis on ultrasound (group 1) were offered a preoperative PSMF diet while the remaining (group 2) proceeded directly to surgery. Between January 2010 and April 2012, patients included in group 1 had liver volume measurements on magnetic resonance imaging the day before the diet was started and the day before the surgery. For the length of the study, intraoperative and postoperative data were recorded for both groups. RESULTS: Five days of preoperative PSMF diet resulted in a significant reduction of total and left liver volume (15.8% and 21% respectively, p < 0.001). There was no difference in intraoperative bleeding and conversion rate or postoperative complication rate between both groups. CONCLUSION: The PSMF diet helps in achieving a rapid decrease in liver volume. Patients with hepatomegaly initially thought to be at a higher risk of intraoperative complications reached comparable rates to patients without hepatomegaly after the diet regimen without any impact on the postoperative course.

Isolated Hepatic Sarcoidosis: A Case Report and Literature Review.

BACKGROUND: Sarcoidosis is a multi-systemic disorder of unknown aetiology that primarily involves the pulmonary system with the histological hall mark of a non-caseating granuloma. Isolated hepatic involvement is a manifestation of sarcoidosis. OBJECTIVE: We report an incidental finding of hepatic sarcoidosis in a hypertensive and diabetic patient who presented with abdominal pain and fatigue. METHODS: A case report of sole diagnosis of hepatic sarcoidosis from a Gastroenterology service in Port Harcourt metropolis Nigeria. A literature search was made using the words 'sarcoidosis' and 'hepatic' in PubMed Central, Cochrane and Google search engines. From the search results, literature in English were extracted and reviewed. RESULTS: The index case was referred on account of hepatomegaly with associated abdominal pain and fatigue. A diagnosis of isolated hepatic sarcoidosis was made from elevated liver enzymes, elevated angiotensin converting enzyme, sero-negative autoimmune studies, hepatomegaly with liver nodule on abdominal computerized tomography scan and non-caseating granuloma from liver biopsy. There was no evidence of other systems involvement. CONCLUSION: Hepatic sarcoidosis is rare in African literature more so as no specific laboratory or radiological test is diagnostic. Delayed diagnosis and underreporting of hepatic sarcoidosis are likely in our environment due to the elaborate evaluation needed.

CONTEXTE: La sarcoïdose est un trouble multisystémique d'étiologie inconnue qui touche principalement le système pulmonaire avec la marque de hall histologique d'un granulome non caséiforme. L'atteinte hépatique isoleé est une manifestation de la sarcoïdose. OBJECTIF: Nous rapportons la découverte fortuite d'une sarcoïdose hépatique chez un patient hypertendu et diabétique qui présentait des douleurs abdominales et de la fatigue. MÉTHODES: Un rapport de cas de diagnostic unique de sarcoïdose hépatique dans un service de gastro-entérologie de Port Harcourt au Nigeria. Une recherche documentaire a été effectuée en utilisant les mots " sarcoïdose " et " hépatique " dans les moteurs de recherche PubMed Central, Cochrane et Google. PubMed Central, Cochrane et Google. A partir des résultats de la recherche, la littérature en anglais a été extraite et examinée. RÉSULTATS: Le cas index a été référé en raison d'une hépatomégalie associée à des douleurs abdominale et fatigue associées. Un diagnostic de sarcoïdose hépatique isolée a été posé à partir de l'élévation des enzymes hépatiques, de l'élévation de l'enzyme de conversion de l'angiotensine, des études auto-immunes séro-négatives, hépatomégalie avec nodule hépatique sur la tomographie abdominale informatisée et tomographie abdominale assistée par ordinateur et granulome non caséiforme à la biopsie du foie. Il n'y avait aucun signe d'atteinte d'autres systèmes. CONCLUSION: La sarcoïdose hépatique est rare dans la littérature africaine d'autant plus que aucun test de laboratoire ou radiologique spécifique n'est diagnostique. Un diagnostic tardif et la sousdéclaration de la sarcoïdose hépatique sont probables dans notre environnement en raison de l'évaluation élaborée nécessaire. MOTS-CLÉS: Sarcoïdose, Foie.

Berardinelli Seip Syndrome: A rare case report.

Berardinelli Seip Congenital Lipodystrophy (BSCL) or Congenital Generalized Lipodystrophy (CGL) is one of the four subgroups of lipodystrophy syndrome which is characterized by varying degrees of loss of adipose mass in the body. It is an extremely rare autosomal recessive disorder and commonly reported clinical presentations include muscular hypertrophy, gigantism, hepatomegaly, impaired glucose tolerance, acanthosis nigricans, hypertriglyceridaemia, cardiomyopathy, intellectual impairment, bone cysts and phlebomegaly. We present a case of a 4.5 years old male child born to consanguineous parents, presented with pneumonia. There was history of recurrent diarrhea and chest infection in the past. He had acromegaly like features, hirsutism, firm hepatomegaly, a well defined bone cyst in proximal right femur, pancytopenias with normal bone marrow biopsy report, hypertriglyceridemia and selective IgA deficiency. This is the first case of BSCL, reported in Pakistan with a bone cyst and IgA deficiency. Such patients need to be identified and monitored for complications like diabetes mellitus and hypertrophic cardiomyopathy.

Haemophagocytic lymphohistiocytosis associated with bartonella peliosis hepatis following kidney transplantation in a patient with HIV.

Bacillary peliosis hepatis is a well recognised manifestation of disseminated Bartonella henselae infection that can occur in immunocompromised individuals. Haemophagocytic lymphohistiocytosis is an immune-mediated condition with features that can overlap with a severe primary infection such as disseminated Bartonella spp infection. We report a case of bacillary peliosis hepatis and secondary haemophagocytic lymphohistiocytosis due to disseminated Bartonella spp infection in a kidney-transplant recipient with well controlled HIV. The patient reported 2 weeks of fever and abdominal pain and was found to have hepatomegaly. He recalled exposure to a sick dog but reported no cat exposures. Laboratory evaluation was notable for pancytopenia and cholestatic injury. The patient met more than five of eight clinical criteria for haemophagocytic lymphohistiocytosis. Pathology review of a bone marrow core biopsy identified haemophagocytosis. A transjugular liver biopsy was done, and histopathology review identified peliosis hepatis. Warthin-Starry staining of the bone marrow showed pleiomorphic coccobacillary organisms. The B henselae IgG titre was 1:512, and Bartonella-specific DNA targets were detected by peripheral blood PCR. Treatment with doxycycline, increased prednisone, and pausing the mycophenolate component of his transplant immunosuppression regimen resulted in an excellent clinical response. Secondary haemophagocytic lymphohistiocytosis can be difficult to distinguish from severe systemic infection. A high index of suspicion can support the diagnosis of systemic Bartonella spp infection in those who present with haemophagocytic lymphohistiocytosis, especially in patients with hepatomegaly, immunosuppression, and germane animal exposures.

Diagnostic value of plasma lysosphingolipids levels in a Niemann-Pick disease type C patient with transient neonatal cholestasis.

OBJECTIVES: Niemann-Pick disease type C (NPC) is a lysosomal storage disease due to impaired intracellular lipid trafficking caused by biallelic pathogenic variants in NPC1 or NPC2 genes. NPC is classified according to the age of onset of neurological manifestations. Cholestatic liver disease can be transient or lead to liver failure. Accompanying neurological findings can be observed at any age. In this report, an infant with a homozygous pathogenic variant in NPC1 gene whose diagnosis was eventually confirmed by specific biomarkers is described. CASE PRESENTATION: A sixteen-day-old male was admitted to hospital with prolonged jaundice. He had mild hepatosplenomegaly, conjugated hyperbilirubinemia, elevated liver transaminases, and mild hypoalbuminemia. Cholestasis resolved spontaneously and patient was readmitted due to progressive hepatosplenomegaly without any neurologic findings when he was 8 months old. Molecular investigations detected homozygous c.1123A > C (p.Thr375Pro) pathogenic variant in NPC1 gene. NPC-specific lysosomal biomarkers such as Lysosphingomyelin and Lysosphingomyelin-509 were elevated, confirming the diagnosis. CONCLUSIONS: The clinical features of NPC are highly heterogeneous, from disease severity or age of onset to disease progression. Patients presenting with transient neonatal cholestasis and should be regularly followed for neurodevelopmental status and visceromegaly. In the case of variants of unknown significance in NPC1 gene, lysosomal biomarkers play an important role when genetic analyses are inconclusive.

Reversible severe glycogenic hepatopathy in type 1 diabetes.

CASE PRESENTATION: We report a case of severe glycogenic hepatopathy in a 17-year-old boy with poorly controlled type 1 diabetes. On presentation, major findings included unexplained pronounced hepatomegaly and increased liver enzymes, ferritin, and triglycerides. Histology and electron microscopy evaluation showed severe glycogen storage, steatosis, and signs of fibrosis, resembling the histomorphological findings of Mauriac syndrome. After information about the nature of the disease and intensification of insulin therapy with insulin pump, liver enzymes, ferritin, and triglycerides normalized within 1 month. CONCLUSION: Glycogenic hepatopathy is a rare but important potential complication in poorly controlled juvenile diabetic patients. With improved metabolic control, it is fully reversible.

Eye pain and blurred vision as main complaints in a new case with MDPL syndrome.

INTRODUCTION: We report a novel phenotype of mandibular hypoplasia, deafness, and progeroid features with lipodystrophy (MDPL) syndrome with POLD1 mutation in a Chinese girl. CASE DESCRIPTION: Diabetic retinopathy was detected as the primary manifestation in a Chinese girl with MDPL syndrome carrying a known POLD1 mutation (c.1812_1814delCTC, p.Ser605del). Typical characteristics of the syndrome including mandibular hypoplasia, deafness, progeroid features, and diabetes were detected after comprehensive examinations. The patient suffered from blurred vision and eye pain due to the neovascularization of the retina (vitreous hemorrhage and retinal detachment) and iris (neovascular glaucoma). The literature review revealed that the prevalence of hepatomegaly and abnormal triglyceride levels were significantly higher in female than in male with MDPL syndrome carrying POLD1 mutations. CONCLUSION: These results expand our knowledge regarding the clinical phenotypes of MDPL syndrome with POLD1 mutations. Diabetic retinopathy is a non-negligible complication of MDPL syndrome. The phenotype varies among female and male patients with the syndrome. Hepatomegaly and abnormal triglyceride levels are more common in female patients with MDPL syndrome.
