Real-world case series and summary of current literature of infants and toddlers with severe hemophilia A with inhibitor on prophylaxis with emicizumab.
Garcia, J, Zia, A
Pediatric blood & cancer. 2021;(5):e28942
Abstract
Emicizumab is a recombinant, humanized, and a bispecific monoclonal antibody that bridges activated factor (F) IX and FX in place of FVIII to restore hemostasis in persons with hemophilia A (PHA). Data on the efficacy and safety of emicizumab in young children is limited. Immunologic naivety, physiologically decreased production of vitamin K dependent proteins, specifically FIX, and enhanced clearance of emicizumab in infants may support decreased emicizumab effectiveness. We report on the facilitation of care rendered by using emicizumab in young PHA with inhibitors and extend data on the efficacy and safety in PHA < 3 years.

Abstract
BACKGROUND Multicentric Castleman's disease is a life-threatening disorder involving a systemic inflammatory response and multiple organ failure caused by the overproduction of interleukin-6. Although renal complications of Castleman's disease include AA amyloidosis, thrombotic microangiopathy, and membranoproliferative glomerulonephritis, membranous nephropathy is relatively rare. We experienced a case of secondary membranous nephropathy associated with Castleman's disease. CASE PRESENTATION The patient was a 43-year-old Japanese man who had shown a high zinc sulfate value in turbidity test, polyclonal hypergammaglobulinemia, anemia, and proteinuria. A physical examination revealed diffuse lymphadenopathy, an enlarged spleen and papulae of the body trunk. A skin biopsy of a papule on the patient's back showed plasma cells in the perivascular area and he was diagnosed with multicentric Castleman's disease, plasma cell variant. Kidney biopsy showed the appearance of bubbling in the glomerular basement membranes in Periodic acid methenamine silver stain and electron microscopy revealed electron dense deposits within and outside the glomerular basement membranes. Since immunofluorescence study showed predominant granular deposition of IgG1 and IgG2, he was diagnosed with secondary membranous nephropathy associated with Castleman's disease. He was initially treated with prednisolone alone, however his biochemical abnormalities did not improve. After intravenous tocilizumab (700 mg every 2 weeks) was started, his C-reactive protein elevation, anemia, and polyclonal gammopathy improved. Furthermore, his urinary protein level declined from 1.58 g/gCr to 0.13 g/gCr. The prednisolone dose was gradually tapered, then discontinued. He has been stable without a recurrence of proteinuria for more than 6 months. CONCLUSIONS Tocilizumab might be a treatment option for secondary membranous nephropathy associated with Castleman's disease.

Abstract
INTRODUCTION Immunotherapy has changed the management of patients with various types of malignancies (melanoma, renal, lung, and bladder cancers) but immune checkpoint inhibitors may be associated with several adverse events. Up to 20% of patients treated with immune checkpoint inhibitors may develop dermatological immune-related adverse events, mostly rashes and pruritus but rarely even bullous pemphigoid. CASE REPORT We report a case of an elderly patient with advanced non-small cell lung cancer in therapy with pembrolizumab, 200 mg/body every three weeks. After 26 cycles of therapy, the patient developed widespread itching and then after 28 cycles she developed strained blisters filled with serous fluids on predominantly erythematous skin with suspicious of bullous pemphigoid.Management and outcome: Skin biopsy confirms bullous pemphigoid, so we decided to permanently discontinue therapy with pembrolizumab and the patient is currently on therapy with doxycycline, nicotinamide, and clobetasol propionate with good regression of symptoms and cutaneous lesions. DISCUSSION In the literature, the first case of bullous pemphigoid induced by pembrolizumab has been described in 2015. On Pubmed, from 2015 to date, we have found 19 cases of bullous pemphigoid during pembrolizumab therapy but only three of them are related to non-small cell lung cancer, adding our patient we reach a total of 20 cases. It could be interesting to investigate if there is a specific relationship between the appearance of itching and the development of bullous pemphigoid.

Abstract
Immune checkpoint inhibitors (ICIs) have improved the overall survival of many patients with advanced cancers. However, unlike cytotoxic and targeted drugs, ICIs may cause various immune-related adverse events (irAEs). Among these irAEs, autoimmune meningitis is very rare. Here, we report a case of early-onset, atezolizumab-induced meningitis after administration of one dose of atezolizumab. A 56-year-old man with lung adenocarcinoma had received seventh-line treatment with atezolizumab when he experienced dysarthria. Blood examinations, including the measurement of electrolytes, glucose, and organ functions, were unremarkable, but enhanced head magnetic resonance imaging T1-weighted images showed meningeal enhancement. Although cerebral spinal fluid (CSF) examinations revealed elevated lymphocyte and protein levels, no cancer cells were detected in the CSF. CSF cultures and serological tests, including polymerase chain reaction for herpes simplex virus, were negative. The patient was therefore diagnosed with atezolizumab-triggered autoimmune meningitis. With steroid treatment, the patient's clinical and neurological state improved immediately and he recovered to baseline conditions. Prompt diagnosis and therapeutic intervention are essential for the effective treatment of autoimmune meningitis.

Abstract
Severe acute respiratory syndrome coranovirus-2 (SARS-CoV-2) infection has become an important health-care issue worldwide. The coronavirus disease 2019 (COVID-19) has also raised concerns among patients with inflammatory rheumatic conditions and their treating physicians. There are emerging data regarding the potential risks of SARS-CoV-2 for this particular patient group. However, less is known with regard to the course of COVID-19 among patients receiving IL-17 inhibitors. The aim of the current article is to review the growing body of knowledge on the course/management of COVID-19 in patients with inflammatory rheumatic diseases by presenting a SARS-CoV-2 infected case with ankylosing spondylitis under secukinumab therapy. A 61-year old patient with ankylosing spondylitis who was on secukinumab therapy for 5 months admitted with newly onset fever and gastrointestinal complaints. After being hospitalized, she developed respiratory manifestations with focal pulmonary ground-glass opacities and multiple nodular densities in both lungs. The patient was tested positive for SARS-CoV-2 infection. Substantial clinical improvement was obtained following a management plan, which included tocilizumab, hydroxychloroquine, prednisolone and enoxaparin sodium. PubMed/MEDLINE and Scopus databases were searched by using relevant keywords and their combinations. The literature search revealed four articles reporting the clinical course of COVID-19 in seven rheumatic patients on secukinumab. The clinical course of SARS-CoV-2 infection was mild in most of these patients, while one of them experienced severe COVID-19. Interleukin-17 has been related to the hyperinflammatory state in COVID-19 and IL-17 inhibitors were presented as promising targets for the prevention of aberrant inflammation and acute respiratory distress in COVID-19. However, this hypothesis still remains to be proved. Further studies are warranted in order to test the benefits and risks of IL-inhibitors in SARS-CoV-2 infected individuals.

Abstract
BACKGROUND Anticoagulation in heart transplant (HT) recipients increases the risk of hemorrhagic complications, so correct reversal of anticoagulation is needed. Dabigatran, a direct thrombin inhibitor, is increasingly used for anticoagulation in patients with non-valvular atrial fibrillation (NVAF) whose effect can be reversed by idarucizumab. AIM: To present a nationwide experience using idarucizumab for the urgent reversal of dabigatran before HT. METHODS Multicenter observational study in 12 Spanish centers to analyze the clinical outcomes after using idarucizumab before HT surgery. RESULTS Fifty-three patients were included (81.1% male). 7.5% required re-operation in the immediate postoperative period to control bleeding and 66% transfusion of blood products. Median length of stay in the intensive care unit was 6 days and total hospital stay 24 days. 30-day survival was 92.4%. There were four deaths in the first month, all in the first 5 days post-HT. Only in one patient (transplanted due to a congenital heart disease, after sternotomy) who had surgical problems and right ventricular failure post-HT death was associated with bleeding. CONCLUSIONS These results may support the use of dabigatran as an alternative to vitamin K antagonists in patients listed for HT requiring anticoagulation due to NVAF. More studies are needed to reaffirm these observations.

Bullous dermatoses secondary to anti-PD-L1 agents: a case report and review of the literature.
Kosche, C, Owen, JL, Sadowsky, LM, Choi, JN
Dermatology online journal. 2019;(10)
Abstract
Immune checkpoint inhibitors are used to treat numerous malignancies but may be associated with severe adverse events. Bullous dermatoses, chiefly bullous pemphigoid (BP), are potentially progressive adverse events that cause blistering skin lesions and may involve a significant body surface area. Herein, we report an 87-year-old man with urothelial cell carcinoma undergoing atezolizumab treatment who presented with an acute-onset blistering eruption. Biopsy revealed a subepidermal bulla, direct immunofluorescence revealed linear IgG and C3 deposits at the dermal-epidermal junction, and serum studies revealed elevated levels of antibodies to BP180 and BP230. Anti-PD-L1-induced BP was diagnosed, immunotherapy was withheld, and he was treated with oral doxycycline with niacinamide and clobetasol ointment. He restarted atezolizumab and has successfully received four cycles (every 3 weeks) while continuing this BP treatment regimen. A literature review revealed eight other cases of anti-PD-L1-induced bullous disorders. The incidence of bullous dermatoses with anti-PD-1/anti-PD-L1 agents combined is 1%, whereas the reported incidence for anti-PD-L1 agents alone ranges from 1.3-5%, raising concerns for a higher overall risk. In addition to our case, only one other case reported successful resumption of immunotherapy. Early control and management of immunotherapy-induced BP may reduce complications and prevent treatment discontinuation.

Osteoblastic bone response mimicking bone progression during treatment with pembrolizumab in advanced cutaneous melanoma.
Comito, F, Ambrosini, V, Sperandi, F, Melotti, B, Ardizzoni, A
Anti-cancer drugs. 2018;(10):1026-1029
Abstract
Pembrolizumab is an immune checkpoint inhibitor approved for the treatment of patients with unresectable or metastatic melanoma. Appearance of bone metastases, either osteolytic or osteoblastic, during treatment qualifies as disease progression. We report the case of a 64-year-old White woman with a metastatic melanoma undergoing second-line treatment with pembrolizumab. At first evaluation, after 3 months of therapy, computed tomography scans showed the onset of osteosclerotic lesions and a significant reduction in all the previously identified metastases; on the contrary, a fluorine-18-fluorodeoxyglucose PET showed the normalization of fluorine-18-fluorodeoxyglucose uptake in all the baseline lesions, including bone metastases. Osteoblastic response, consisting of occurrence of new osteoblastic lesions on computed tomography imaging, as a consequence of an osteoblastic reaction of previously undetectable bone metastases, has been reported in some cancers that receive treatments such as chemotherapy, hormonal or targeted therapy. However, it had never been reported in patients with melanoma treated with immunotherapy. An apparent worsening of bone imaging on standard computed tomography scan in patients under checkpoint inhibitor should not lead to modification of treatment strategy, because misinterpretation as disease progression may lead to the premature cessation of a beneficial treatment and finally have a negative effect on patients' clinical outcome.

SIADH in Systemic JIA Resolving After Treatment With an IL-6 Inhibitor.
Hodax, JK, Bialo, SR, Yalcindag, A
Pediatrics. 2018;(1)
Abstract
Interleukin-6 (IL-6) is implicated in the pathogenesis of both systemic juvenile idiopathic arthritis (SJIA) and syndrome of inappropriate secretion of antidiuretic hormone (SIADH), but the 2 have not been previously described as occurring together. We report a case of a 6-year-old girl with symptoms of arthralgia, daily fevers, evanescent rash, lymphadenopathy, and laboratory evaluation showing elevated inflammatory markers, consistent with SJIA. At presentation, the patient had hyponatremia with a sodium level of 128 mEq/L. She had low serum osmolality with elevated urine osmolality, consistent with SIADH. Hyponatremia improved temporarily during times of fluid restriction as expected in SIADH, but did not resolve until SJIA was treated successfully with tocilizumab, an IL-6 receptor antibody that inhibits IL-6 activity. The positive response to treatment with tocilizumab supports the role of IL-6 in the pathogenesis of both SJIA and SIADH. Patients with SJIA should be monitored for SIADH to avoid complications of untreated hyponatremia.
