Safety and tolerability of intravenous immunoglobulin infusion in Down syndrome regression disorder.

Three large multi-center studies have identified the clinical utility of intravenous immunoglobulin (IVIg) in the treatment of Down syndrome regression disorder (DSRD). Yet the tolerability of infusions in individuals with DS and the safety of IVIg remains unknown in this population. This study sought to evaluate the safety and tolerability of IVIg in individuals with DSRD compared to a real-world cohort of individuals with pediatric onset neuroimmunologic disorders. A single-center, retrospective chart review evaluating clinically documented infusion reactions was performed for individuals meeting international consensus criteria for DSRD and having IVIg infusions between 2019 and 2023. Infusion reactions were evaluated for severity and need for alterations in infusion plan. This cohort was compared against an age and sex matched cohort of children with neuroimmunologic conditions who had also received IVIg infusions. In total, 127 individuals with DSRD and 186 individuals with other neuroimmunologic disorders were enrolled. There was no difference in the overall rate of adverse reactions (AEs) between the DSRD and general neuroimmunology cohorts (p = 0.31, 95% CI: 0.80-2.00), but cardiac-related AEs specifically were more common among the DSRD group (p = 0.02, 95% CI: 1.23-17.54). When AEs did occur, there was no difference in frequency of pharmacologic intervention (p = 0.12, 95% CI: 0.34-1.13) or discontinuation of therapy (p = 0.74, 95% CI: 0.06-7.44). There was a higher incidence of lab abnormalities on IVIG among the general neuroimmunology cohort (p = 0.03, 95% CI: 0.24-0.94) compared to the DSRD cohort. Transaminitis was the most common laboratory abnormality in the DSRD group. In a large cohort of individuals with DSRD, there were no significant differences in the safety and tolerability of IVIg compared to a cohort of children and young adults with neuroimmunologic conditions.

Daily compared with alternate-day levamisole in pediatric nephrotic syndrome: an open-label randomized controlled study.

BACKGROUND: Levamisole is less expensive and has a better toxicity profile compared to other steroid sparing agents used in nephrotic syndrome. It has a plasma half-life of 2.0 to 5.6 hours, but is conventionally administered on alternate days. We aimed to assess whether daily levamisole is safe and more effective than standard alternate-day therapy in maintaining remission in children with frequently relapsing or steroid-dependent nephrotic syndrome (FR/SDNS). METHODS: An open-label randomized controlled trial was conducted in children with FR/SDNS. Group A received daily while Group B received alternate-day levamisole (2-3 mg/kg/dose) for 12 months. Prednisolone was tapered off by 3 months. Patients were monitored for relapses, further steroid requirement, and adverse effects. RESULTS: A total of 190 children with FR/SDNS (94 in Group A and 96 in Group B) were analyzed. Sustained remission for 12 months was observed in 36% of Group A and 27% of Group B patients (p = 0.18). Numbers completing 12 months in the study were 67% in Group A and 56% in Group B (p = 0.13). Time to first relapse, persistent FR/SDNS, and withdrawal due to poor compliance were statistically similar in both groups, while relapse rate and cumulative steroid dosage were significantly lower in Group A compared to Group B (p = 0.03 and p = 0.02, respectively). The incidence of adverse effects was comparable in both groups, with reversible leucopenia and hepatic transaminitis being the commonest. CONCLUSIONS: Daily levamisole therapy was not superior to alternate-day therapy in maintaining sustained remission over 12 months. Nevertheless, relapse rate and cumulative steroid dosage were significantly lower without increased adverse effects.

Gastrointestinal and hepatic manifestations in patients with generalised pustular psoriasis.

Generalised pustular psoriasis (GPP) is a rare and severe form of pustular psoriasis. It is defined by persisting or relapsing macroscopically visible sterile primary pustules occurring on non-acral skin and not within psoriasis plaques. Due to its rarity, there is a lack of randomised controlled trials on GPP and its associated gastrointestinal (GI) and liver disorders. In this article, we present a review of the GI and hepatic disorders associated with GPP. GPP is known to be associated with extracutaneous manifestations such as neutrophilic cholangitis. Abnormal liver function tests are reported in up to 90% of patients with GPP upon diagnosis. Less commonly, pancreatitis and gastrointestinal bleeding have been attributed to GPP. While a psoriasis registry with 7.5% prevalence of pustular psoriasis reported an association with viral hepatitis B and C, the true relationship remains to be elucidated as hepatitis B is endemic in Asia where GPP prevalence is higher. Common genetic mutations between GPP and conditions such as hepatocellular carcinoma and inflammatory bowel disease have been identified, explaining their possible associations and providing answers to potential therapeutic options for these conditions. A lack of recognition of these association may result in unnecessary withdrawal of efficacious and definitive drugs for the treatment of GPP. Understanding the characteristics of the associated GI and hepatic disorders will have important implications for targeting the appropriate therapeutics.

Elevated transaminases and development of cardiomyopathy in a 32-year-old woman with metastatic breast cancer after treatment with ribociclib followed by palbociclib.

INTRODUCTION: Cyclin-dependent kinase 4 and 6 inhibitors, ribociclib and palbociclib, are associated with reports of transaminitis and adverse cardiac events. CASE REPORT: The patient is a previously healthy 32-year-old female diagnosed with estrogen receptor-positive, progesterone receptor-positive, and human epidermal growth factor 2 negative metastatic breast cancer. From July to September 2021, the patient was initiated on ribociclib followed by palbociclib for metastatic breast cancer. She subsequently experienced two episodes of transaminitis and was diagnosed with cardiomyopathy. MANAGEMENT AND OUTCOME: The patient experienced transaminitis 2 weeks after the initiation of ribociclib resulting in discontinuation. When rechallenged with palbociclib, the patient experienced transaminitis within 1 week of initiation, which resulted in discontinuation. Approximately 1 month after palbociclib discontinuation, the patient was diagnosed with congestive heart failure with a left ventricular ejection fraction of 24%. DISCUSSION: To our knowledge, there are few case studies investigating cyclin-dependent kinase 4 and 6 inhibitor rechallenge following transaminitis. Prior literature suggests that transaminitis with cyclin-dependent kinase 4 and 6 inhibitors is not a class effect, but this case report suggests otherwise. This report presents a rare case of cardiomyopathy and transaminitis following the administration of cyclin-dependent kinase 4 and 6 inhibitors, ribociclib and palbociclib.

Acute Budd Chiari syndrome in an ECMO patient.

INTRODUCTION: Point-of-care ultrasound (POCUS) is widely utilized to make timely decisions regarding patient care. This approach allowed us to diagnose the cause of acutely rising transaminases in a patient in severe ARDS secondary to influenza pneumonia requiring veno-venous extracorporeal membrane oxygenation (VV-ECMO). CASE REPORT: A 36-year-old female presented with acute hypoxemic respiratory failure secondary to influenza A infection. Within 24 hours, she required intubation and met severe ARDS criteria with a PaO2/FiO2 ratio of 62. She was managed with high PEEP and low tidal volume ventilation strategy, however her clinical status continued to deteriorate and the decision was made to pursue VV-ECMO. Within hours of cannulation her aspartate aminotransferase (AST) dramatically increased from 736 to 4512 µ/L, with concurrent mild increases in alanine aminotransferase (ALT) and creatine phosphokinase (CPK). Point-of-care ultrasound was performed which revealed a complete absence of flow in the hepatic vein, secondary to acute obstruction by an 25-French drainage catheter for the ECMO circuit. The catheter was exchanged with a smaller French catheter and the patient's transaminases and CPK levels quickly decreased and returned to normal within several days. DISCUSSION: Budd-Chiari syndrome (BCS) is a rare but potentially life-threatening condition caused by acute obstruction of hepatic vein blood flow that can lead to fulminant liver failure if left untreated. BCS is usually caused by a hepatic vein thrombus, however any mechanical obstruction can lead to the same pathology. Point-of-care ultrasound lead to a prompt diagnosis and allowed for quick action to correct the obstruction. Although BCS is not a common problem with VV-ECMO, the syndrome should always be on the differential of any patient on VV-ECMO with acutely rising transaminases. CONCLUSION: Ultrasound played an integral role in providing a crucial diagnosis of BCS secondary to obstruction by an ECMO drainage catheter.

Hepatic safety of repeated treatment with pyronaridine-artesunate versus artemether-lumefantrine in patients with uncomplicated malaria: a secondary analysis of the WANECAM 1 data from Bobo-Dioulasso, Burkina Faso.

BACKGROUND: The use of pyronaridine-artesunate (PA) has been associated with scarce transaminitis in patients. This analysis aimed to evaluate the hepatic safety profile of repeated treatment with PA versus artemether-lumefantrine (AL) in patients with consecutive uncomplicated malaria episodes in Bobo-Dioulasso, Burkina Faso. METHODS: This study analysed data from a clinical trial conducted from 2012 to 2015, in which participants with uncomplicated malaria were assigned to either PA or AL arms and followed up to 42 days. Subsequent malaria episodes within a 2-years follow up period were also treated with the same ACT initially allocated. Transaminases (AST/ALT), alkaline phosphatase (ALP), total and direct bilirubin were measured at days 0 (baseline), 3, 7, 28 and on some unscheduled days if required. The proportions of non-clinical hepatic adverse events (AEs) following first and repeated treatments with PA and AL were compared within study arms. The association of these AEs with retreatment in each arm was also determined using a logistic regression model. RESULTS: A total of 1379 malaria episodes were included in the intention to treat analysis with 60% of all cases occurring in the AL arm. Overall, 179 non-clinical hepatic AEs were recorded in the AL arm versus 145 in the PA arm. Elevated ALT was noted in 3.05% of treated malaria episodes, elevated AST 3.34%, elevated ALP 1.81%, and elevated total and direct bilirubin in 7.90% and 7.40% respectively. Retreated participants were less likely to experience elevated ALT and AST than first episode treated participants in both arms. One case of Hy's law condition was recorded in a first treated participant of the PA arm. Participants from the retreatment group were 76% and 84% less likely to have elevated ALT and AST, respectively, in the AL arm and 68% less likely to present elevated ALT in the PA arm. In contrast, they were almost 2 times more likely to experience elevated total bilirubin in both arms. CONCLUSIONS: Pyronaridine-artesunate and artemether-lumefantrine showed similar hepatic safety when used repeatedly in participants with uncomplicated malaria. Pyronaridine-artesunate represents therefore a suitable alternative to the current first line anti-malarial drugs in use in endemic areas. Trial registration Pan African Clinical Trials Registry.

Hepatobiliary Adverse Events.

Immune checkpoint inhibitors (ICIs) are increasingly used for multiple cancer types. Hepatotoxicity is a reported adverse event of ICI treatment. It can present as asymptomatic elevation of aspartate transaminase and alanine transaminase or symptomatic hepatitis with fever, malaise, and even death in rare cases. The diagnosis of ICI-induced hepatitis is made after exclusion of other etiologies based on medical history, laboratory evaluation, and imaging and histological findings. Treatment of ICI-induced hepatitis consists of ICI discontinuation and immunosuppression in severe cases. Pancreatic injury as asymptomatic lipase elevation or acute pancreatitis-like disease with abdominal pain and evidence on imaging has been documented as a toxicity of ICI therapy. Appropriate treatment of pancreatitis still needs further investigation. Few cases, reports, and series documented cholecystitis and cholangitis as possible adverse events related to ICI therapy as well.

Unusual Etiology for Transaminitis.

An infection with Enterobius vermicularis (pinworm) commonly affects the gastrointestinal (GI) tract. The ectopic localization of an enterobius infectious is rare, especially in the liver. We report the case of a 37-year-old man who presented to the gastroenterology clinic with abdominal pain and was found to have elevated transaminases. Workup for acute/chronic liver disease was unrevealing. He underwent endoscopic evaluation showing a live pinworm in the colon. He was treated with albendazole with improvement in GI symptoms and resolution of his transaminitis. There are scarce reports in the literature describing pathognomonic, clinical, imaging, and laboratory findings for pinworm infection. Here, we attempt to review the literature for hepatic involvement with an enterobius infection and discuss the findings via this case.

Letermovir associated hepatic transaminitis: A case report.

Letermovir is an antiviral agent recently approved by the Food and Drug Administration for prophylaxis of cytomegalovirus infection in adult patients that are cytomegalovirus-seropositive recipients of an allogeneic hematopoietic stem cell transplant. Liver toxicity was not observed in the clinical trials that led to its approval. This report highlights a case of letermovir associated transaminitis with successful rechallenge through peak and recovery of the hepatic serum enzymes. Because there is currently no published evidence to support the adverse event, the temporal relationship and response to rechallenge that was observed is essential to establishing the probable causality in this case.

Clinical Profile and Outcome of Dengue Fever in Multidisciplinary Intensive Care Unit of a Tertiary Level Hospital in India.

BACKGROUND: India is one of the seven identified countries in South-East Asia region regularly reporting dengue fever (DF)/dengue hemorrhagic fever (DHF) outbreaks. Even though the dengue prodrome and evolution of illness are most often similar in many patients, progress and outcome may differ significantly depending on the severity of illness as well as treatment instituted. We studied the clinical manifestations, outcome and factors predicting mortality of serology confirmed dengue fever cases admitted in Multidisciplinary Intensive Care Unit (MICU) of a high acuity healthcare facility in India. METHODOLOGY: All patients with serology proven dengue fever admitted to MICU between 1st July 2015 and1st December 2015 were included in the study. Clinical presentation, laboratory findings, severity of illness scores and outcome were recorded. RESULTS: Majority of the patients (58.4%) belonged to 21-40 year age group. Hepatic (96.8%) followed by hematological (79.2%) involvement were the most common findings. CNS involvement observed among 27%. Survival to hospital discharge was 78.9%. Respiratory and gastrointestinal system involvement was associated with increased mortality. Acute respiratory distress syndrome (ARDS), acute kidney injury (AKI) and shock were the clinical syndromes associated with mortality. Serum lactate, aspartate transaminase (AST) and alanine transaminase (ALT) were significantly elevated among non survivors. Significant difference in sequential organ failure assessment (SOFA) and acute physiology and chronic health evaluation (APACHE) scores was also observed among survivors and non survivors. CONCLUSION: Organ system involvement and higher disease severity scores are strong predictors of mortality. High index of suspicion for atypical manifestations of dengue is warranted.

Immune Checkpoint Inhibitors-Induced Hepatitis.

Immune checkpoint inhibitors (ICIs) have been increasingly used for multiple cancer types in the past decade. ICIs include CTLA-4 inhibitors (e.g., ipilimumab) and the PD-1 and PD-L1 inhibitors (e.g., nivolumab and pembrolizumab). Hepatotoxicity is not uncommon secondary to ICI treatment. It can occur 8-12 weeks after the initiation of ICI and presents with elevation of aspartate transaminase and alanine transaminase. ICI-induced hepatitis is usually asymptomatic but may present with fever, malaise, and even death in rare cases. It is a diagnosis of exclusion after other etiologies are excluded based on medical history, laboratory evaluation, and imaging and histological findings. ICI-induced hepatitis might require discontinuation of ICI and/or treatment with immunosuppressants.

Fifteen-minute consultation: The child with an incidental finding of elevated aminotransferases.

It is not unusual to encounter abnormal liver enzyme levels on routine blood tests. When the abnormal elevation in aminotransferases persist, they require prompt and appropriate investigations as liver diseases in children are often insidious in onset and clinically silent. This article aims to provide (1) an explanation to the aetiologies of elevated aminotransferases; (2) an investigational approach to these children and (3) an insight into further investigations performed at a liver centre.

Biochemical Profile of Nonalcoholic Fatty Liver Disease Patients in Eastern India with Histopathological Correlation.

Aminotransferase assay is often used as a screening test as well as an endpoint for resolution of disease in nonalcoholic fatty liver disease (NAFLD). Aim of the study was to evaluate the relationship of transaminase level with metabolic variables and histology in NAFLD. Single center observational study was conducted in a gastroenterology clinic at Cuttack in coastal Odisha. Subjects were consecutive patients presenting with functional bowel disease and undergoing abdominal sonography. All participants were evaluated for the presence of metabolic syndrome (MS), insulin resistance, liver function test and lipid profile. Various parameters were compared between NAFLD subjects and controls. 53.5 % of NAFLD had normal serum transaminases, whereas 20.8 % of healthy controls had transaminitis. NAFLD patients had significantly higher BMI, fasting plasma glucose, serum transaminases, serum triglycerides, serum insulin and homeostatic model assessment (HOMA) IR than controls. NAFLD patients who had transaminitis had significantly higher incidence of MS and higher mean HOMA IR than those without. There was no significant difference in histopathological features between NAFLD with and without transaminitis. To conclude, over half of NAFLD subjects do not have transaminitis while transaminitis is present in a fifth of healthy people without fatty liver. Hence serum transaminase should not be used as screening test for NAFLD. NAFLD patients with transaminitis had a higher incidence of MS and insulin resistance than those without. However, there was no significant difference in histopathological features between these two groups.

Oxcarbazepine-induced liver injury after sensitization by valproic acid: a case report.

OBJECTIVE: The aim of the present case report is to describe a potential interaction between valproic acid and oxcarbazepine that resulted in hepatic injury. METHODS: We report the case of a 46-year-old man with schizoaffective disorder who was cross-titrated from valproic acid to oxcarbazepine because of liver injury. RESULTS: Initiation of oxcarbazepine four days after stopping valproic acid produced a significant elevation in liver enzymes that normalized with oxcarbazepine discontinuation and did not reappear with its reintroduction five days later. CONCLUSIONS: Our findings suggest that a longer washout period or another agent should be considered when transitioning from valproic acid to oxcarbazepine.

Standardized laboratory monitoring with use of isotretinoin in acne.

BACKGROUND: Laboratory monitoring for adverse effects to isotretinoin occurs with variability. Standardization of laboratory monitoring practices represents an opportunity to improve quality of care. OBJECTIVE: We sought to develop an evidence-based approach to laboratory monitoring of patients receiving isotretinoin therapy for acne. METHODS: We reviewed laboratory data from 515 patients with acne undergoing 574 courses of isotretinoin from March 2003 to July 2011. Frequency, timing, and severity of abnormalities were determined. RESULTS: Clinically insignificant leukopenia or thrombocytopenia occurred in 1.4% and 0.9% of patients, respectively. Elevated liver transaminases were detected infrequently and not significantly increased compared with baseline detection rates (1.9% vs 1.6% at baseline). Significant elevations occurred with triglyceride (19.3%) and cholesterol (22.8%) levels. The most severe abnormalities were grade 2 (moderate). Mean duration of treatment before abnormalities were detected was 56.3 days for hypertriglyceridemia, 61.9 days for alanine transaminitis, and 50.1 days for hypercholesterolemia. LIMITATIONS: This was a single-center experience examining variable isotretinoin laboratory monitoring practices. CONCLUSIONS: In healthy patients with normal baseline lipid panel and liver function test results, repeated studies should be performed after 2 months of isotretinoin therapy. If findings are normal, no further testing may be required. Routine complete blood cell count monitoring is not recommended.

Rare medical manifestations of severe restricting and purging: "Zebras," missed diagnoses, and best practices.

OBJECTIVE: Medical problems that arise due to severe restricting and/or purging may be misdiagnosed or suboptimally treated, from outpatient clinics to top medical hospitals. A symptom may be presumed to be a psychological manifestation of the eating disorder and inappropriately dismissed for further medical evaluation. Alternatively, a detailed medical workup may be performed, overlooking a classic relationship between starvation and a physical finding, which delays referral to eating disorder care. This review article focuses on rare medical issues (also called "zebras" in medical training), diagnoses that may be missed in patients with eating disorders, and best practices for management, organized by organ system. METHOD: A PubMed search was performed, using search terms "eating disorder," "anorexia nervosa," and "bulimia nervosa" in combination with different words for each organ system and known medical manifestations of severe eating disorders, with high quality and relevant studies from the past 20 years cited. DISCUSSION: Adults with eating disorders may present with extreme organ dysfunction and atypical signs and symptoms of typical medical problems. Timely diagnosis, risk awareness, appropriate treatment, and avoidance of harm are all vital. With judicious management and nutritional rehabilitation, most of these complications will significantly improve or resolve. ©

Glycogenic hepatopathy is an under-recognised cause of hepatomegaly and elevated liver transaminases in type 1 diabetes mellitus.

Glycogenic hepatopathy (GH) is an under-recognised complication of type 1 diabetes mellitus (T1DM) not controlled to target resulting in hepatomegaly and elevated liver transaminases. We report the case of a 19-year-old man with T1DM not controlled to target who presented with abdominal pain, hepatomegaly and deranged liver transaminases. He was subsequently diagnosed with GH on liver biopsy, with the mainstay of treatment being reduction in caloric intake and insulin.

Is excessive acetaminophen intake associated with transaminitis in adult patients with dengue fever?

BACKGROUND: Dengue, an endemic infection causing severe flu-like symptoms and fever, is often treated with high-dose acetaminophen that can exceed recommended daily dosages. This leads to hepatotoxicity, although the underlying mechanism is poorly understood. We hypothesised that excessive acetaminophen causes hepatic toxicity in dengue patients. AIMS: To investigate a correlation between elevated serum transaminases and excessive acetaminophen intake, and other aggravating factors of liver injury in dengue cases. METHODS: This prospective observational study obtained blood samples from 150 participants with acute febrile illness for dengue serological tests, blood counts, and the detection of serum transaminases and acetaminophen levels. Other factors were determined by questionnaire. RESULTS: Of 150 participants enrolled, 77 had dengue fever. Abnormally high serum aspartate transaminase and alanine transaminase levels were present in 97.0% and 75.3% of dengue cases respectively. Multivariate analysis of cases with increased serum transaminases more than threefold normal upper limits indicated that male gender (odds ratio (OR) = 3.62, 95% confidence interval (CI) 1.38-9.42) and consuming >8 g acetaminophen orally (OR = 4.62, 95% CI 1.37-13.18) correlated with transaminitis. No correlation was found for other factors such as age, fever day at presentation, body mass index, alcohol intake or dengue severity classification (all P > 0.05). Chronic alcohol consumption was higher in non-dengue (2.6%) versus dengue cases (27.8%) (P < 0.01). CONCLUSIONS: Most dengue patients had mild-to-moderate transaminitis. Male gender and acetaminophen >8 g were associated with increased serum transaminases. Thus, 1000 mg acetaminophen every 8 h or <3000 mg/day is recommended for dengue cases. Chronic alcohol consumption might be protective against dengue infection.

Transient liver function abnormality following treatment with rabbit antithymocyte globulin for nonmyeloablative hematopoetic stem cell transplant: two case reports.

Rabbit antithymocyte globulin (rATG) is increasingly used in nonmyeloablative hematopoetic stem cell transplant (HSCT). Elevated liver function tests (LFTs) have been reported for antithymocyte globulin in the treatment of aplastic anemia, but not when used in a conditioning regimen for HSCT. We describe two cases of patients receiving a conditioning regimen for HSCT containing rATG who developed a transient, severe transaminase elevation. In the first case, a 66-year-old woman with a history of acute myeloid leukemia received the first dose of rATG and the patient's transaminases were found to be extremely elevated within a few hours. The aspartate transaminase (AST) peaked at 1286 U/L and alanine transaminase (ALT) peaked at 991 U/L and both resolved within a week. In the second case, a 72-year-old woman with a history of non-Hodgkin lymphoma received the first dose of rATG and the AST and ALT were found to be 1212 U/L and 689 U/L, respectively, 1 h after finishing the infusion. Like the previous case, the transaminase elevation resolved within a week. LFT abnormalities induced by rATG during conditioning therapy for HSCT may be transient and have a rapid onset after the first dose, but quickly subside without any complications or sequelae. It is important to follow the LFTs closely, as well as monitor for any signs and symptoms of acute liver failure.

Acute Severe Ulcerative Colitis Flare Complicated by Myopericarditis and Infliximab-Induced Hepatitis.

Ulcerative colitis (UC) is an autoimmune disease associated with both intestinal and extraintestinal manifestations. The latter may include heart complications, such as myopericarditis leading to life-threatening arrythmias. Nowadays, UC is commonly treated with biologic medications and infliximab is the first line therapy in an outpatient setting, while it is also used as rescue therapy in acute severe UC. However, it has been associated with severe immunosuppression, cytomegalovirus (CMV) reactivation and drug-induced hepatitis. We report a case of UC flare in a biologic naïve patient admitted with myopericarditis, which was further complicated by positive CMV biopsies and infliximab-induced transaminitis. LEARNING POINTS: In acute inflammatory bowel disease (IBD) flare presentation with tachycardia and chest pain, an underlying myocardial injury should be investigated.Mucosal healing should be evaluated endoscopically in cases of partial response to biologics.Both cytomegalovirus (CMV) infection and infliximab-induced liver injury may lead to acute hepatitis.
