Immune checkpoint inhibitor-related acquired amegakaryocytosis thrombocytopenia: a case report and literature review.

Introduction: Immune checkpoint inhibitors (ICIs) are used in several advanced malignancies and may cause various immune-related adverse events (irAEs). Among them, hematological irAEs are less described. Acquired amegakaryocytic thrombocytopenia (AAT) is a rare immune hematologic disorder characterized by severe thrombocytopenia and complete absence of megakaryocytes in bone marrow. Case presentation: Herein, we present the case of a patient in their 40s with metastatic melanoma who developed an AAT after 12 cycles of nivolumab (anti-PD1). His platelet count decreased by ≤5 × 109/l without other cytopenia. Bone marrow biopsy showed normal cellularity with a complete absence of megakaryocyte and T-CD8+ lymphocyte infiltration. Given the failure of systemic steroids, eltrombopag was started, an oral thrombopoietin receptor agonist (TPO-RA), and his platelet count subsequently increased with complete response. Discussion: Four other cases are described on literature with the same features than non-ICI-related AAT. All cases occurred after anti-PD/PD-L1 treatment with a median onset of 5 weeks. The presentation of our case is quite different with delayed cytopenia. Both ciclosporin and TPO-RA seem to be efficient therapies. Conclusion: TPO-RA could be preferred in oncologic patients, but safety data are still missing to define clear guidelines for immune-related AAT management.

High prevalence of malnutrition in systemic sclerosis: Results from a French monocentric cross-sectional study.

OBJECTIVES: Systemic sclerosis (SSc) can cause malnutrition due to frequent gastrointestinal involvement. However, prevalence of malnutrition in SSc is poorly known. The aim of this study was to evaluate the prevalence of malnutrition in SSc and its potential associations with disease features in patients from a tertiary referral center. METHODS: All patients meeting American College of Rheumatology/European Alliance of Associations for Rheumatology criteria for SSc followed between January 1, 1985, and January 1, 2019, at the Department of Internal Medicine, Saint Eloi University Hospital, were included. Malnutrition was assessed using the 2020 French recommendations for SSc and the malnutrition universal screening tool score. Severe malnutrition was defined via the French Haute Autorité de Santé (National Health Authority) 2007 criteria. RESULTS: A total of 120 patients were included, with mean age 64 (± 15) y and a female-to-male sex ratio of 5:1. According to 2020 French recommendations, 71 patients (59.2%) were malnourished and 30 (25%) had at least one criterion of severe malnutrition. With the malnutrition universal screening tool score, 41.7%, 20%, and 38.3%, respectively, had low, medium, and high risk of malnutrition. Multivariate analysis revealed the following results: 1) malnutrition was associated with cardiac involvement (P < 0.01); 2) a high malnutrition universal screening tool score was also associated with specific cardiac involvement (P < 0.01); and 3) severe malnutrition was strongly correlated with interincisal distance <35 mm (P = 0.02). CONCLUSIONS: Malnutrition affects more than half of SSc patients and is associated with specific cardiac involvement. Interincisal distance <35 mm could be a red flag for severe malnutrition in SSc.

Clinical pattern of checkpoint inhibitor-induced liver injury in a multicentre cohort.

Background & Aims: Immune checkpoint inhibitors (ICIs) have changed the landscape of cancer therapy. Liver toxicity occurs in up to 25% of patients treated with ICIs. The aim of our study was to describe the different clinical patterns of ICI-induced hepatitis and to assess their outcome. Methods: We conducted a retrospective observational study of patients with checkpoint inhibitor-induced liver injury (CHILI) discussed in multidisciplinary meetings between December 2018 and March 2022 in three French centres specialised in ICI toxicity management (Montpellier, Toulouse, Lyon). The hepatitis clinical pattern was analysed by the ratio of serum alanine aminotransferase (ALT) and alkaline phosphatase (ALP) (R value = (ALT/ULN)/(ALP/ULN)) for characterisation as cholestatic (R ≤2), hepatocellular (R ≥5), or mixed (2

Long-term home parenteral nutrition in systemic sclerosis-related intestinal failure is feasible but unveils occult cardiac disease.

OBJECTIVE: The aim of this study was to compare safety and efficacy of long-term home parenteral nutrition between patients with systemic sclerosis and intestinal failure (IF) and controls with IF from another etiology. METHODS: A retrospective study was conducted in a referral center for systemic sclerosis (SSc) in Montpellier, France. Patients followed between 1985 and 2020 with SSc-related IF were included and compared with control patients with IF from another etiology. The patients included had to be treated for ≥4 wk by home parenteral nutrition (HPN). Primary outcome was occurrence of HPN-related complications. Secondary outcomes included duration of parenteral nutrition, body mass index at 12 mo, and survival. RESULTS: Cumulative duration of HPN was 23 397 catheter days. HPN resulted in body mass index increase in both groups. There was no statistical difference regarding catheter-related bloodstream infections and thrombosis between the groups, despite use of immunosuppressive drugs and autologous hematopoietic stem cell transplantation in patients with SSc. However, the patients with SSc had significantly more HPN-related cardiac overload than the controls (P < 0.0001). Overloads occurred in SSc patients with and without cardiac disease, arguing for comprehensive hemodynamic screening in this condition. CONCLUSION: Long-term HPN in SSc-related IF is feasible but unveils occult cardiac disease.
