Behçet Disease Associated With Myelodysplastic Syndrome

Ophthalmic Manifestations in Patients with Blood Malignancies

Ocular complications can occur in up to 90% of patients with blood malignancies. Such complications range from direct infiltration to local hemostatic imbalance and treatment-related toxicity. This narrative review is based on a systematic computerized search of the literature conducted until January 2024 and examines the common ocular complications associated with blood cancers. Ocular complications from primary disease include mass effects from ocular adnexal lymphomas and intraocular lymphomas, with B-cell lymphomas accounting for 95% of primary ocular presentations. Secondary disease involvement from systemic hematological malignancies can lead to a wide range of ocular manifestations, such as leukemic retinopathy. Furthermore, toxicity from antineoplastic therapies and ocular graft versus host disease (oGVHD) after hematopoietic stem cell transplantation present additional risks to ocular health. In conclusion, ocular complications in blood cancer patients are an integral part of patient management, requiring regular ophthalmic evaluations and close collaboration between oncologists and ophthalmologists. Advances in therapy and an increased focus on early symptom recognition are essential for preserving vision and enhancing patient quality of life.

Osteonecrosis as a rare musculoskeletal complication in Behcet's disease- the largest case series with literature review

BACKGROUND

Behcet disease (BD) as a variable vessel vasculitis is mainly characterized by ocular involvement, genital and oral aphthosis, and erythema nodosum. However, major organ involvements including gastrointestinal involvement, nervous system, and vascular involvement are among the severe complications. Osteonecrosis is a rare complication of patients with BD. We aim to report the largest series of BD patients suffering from osteonecrosis.

METHODS

We have retrospectively reviewed all patients in Iran Behcet's Disease Registry and reported those with osteonecrosis. Patients' medication and clinical features, symptoms, and details of osteonecrosis will also be presented. Furthermore, previously reported cases will also be reviewed.

RESULTS

Seven thousand eight hundred thirty-one patients were diagnosed with BD and registered. 18 patients developed ON with an incidence of 0.22%. The most common involvement during the disease progression was oral aphthosis which appeared in 100% of patients followed by ocular involvement in 85.7% and skin involvement in 71.4%. Vascular, ocular, and nervous system involvements are significantly higher in BD patients with osteonecrosis than the other BD patients. For the management of acute episode of uveitis, deep vein thrombosis, severe gastrointestinal involvement, arterial involvement, nervous system Involvement, and joint involvement high dose of glucocorticoids is indicated.

CONCLUSIONS

ON tends to appear as a multifocal involvement in BD patients, hence, after diagnosis of ON in one joint other possible sites of ON should be investigated.

[Behçet's-like syndrome and other dysimmunitary manifestations related to myelodysplastic syndromes with trisomy 8]

Myelodysplastic syndromes (MDS) are clonal hematopoietic malignancies which are also characterised by immune dysregulation. The impaired immune response is mainly due to T lymphocytes (CD8 and T regulatory cells) with increased cell apoptosis. MDS could be associated in some cases with various clinical dysimmune features; however, only MDS with trisomy 8 is correlated with particular clinical phenotype. The latter is mainly Behçet's-like disease which includes orogenital aphtosis, skin features and severe ulcerative digestive disease of ileocaecal distribution. Other clinical manifestations, such as arthritis or neutrophilic dermatosis, have been also described in MDS patients with trisomy 8. The dysimmune manifestations, and among them the Behçet's-like disease, do not impact the overall survival or the risk of progression to acute myeloid leukemia. Immunosuppressive and immunomodulatory therapies, and among them TNF-α inhibitors, are usually ineffective to control the dysimmune manifestations. Targeting the underlying clonal disease with specific therapies, such as azacitidine, seems to be the best strategy to control these disorders, even in MDS patients with low-risk disease.

Behçet disease (BD) and BD-like clinical phenotypes: NF-κB pathway in mucosal ulcerating diseases

Behçet's disease (BD) is a heterogeneous multi-organ disorder in search of a unified pathophysiological theory and classification. The disease frequently has overlapping features resembling other disease clusters, such as vasculitides, spondyloarthritides and thrombophilias with similar genetic risk variants, namely HLA-B*51, ERAP1, IL-10, IL-23R. Many of the BD manifestations, such as unprovoked recurrent episodes of inflammation and increased expression of IL-1, IL-6 and TNFα, overlap with those of the hereditary monogenic autoinflammatory syndromes, positioning BD at the crossroads between autoimmune and autoinflammatory syndromes. BD-like disease associates with various inborn errors of immunity, including familial Mediterranean fever, conditions related to dysregulated NF-κB activation (eg TNFAIP3, NFKB1, OTULIN, RELA, IKBKG) and either constitutional trisomy 8 or acquired trisomy 8 in myelodysplastic syndromes. We review here the recent advances in the immunopathology of BD, BD-like diseases and the NF-κB pathway suggesting new elements in the elusive BD etiopathogenesis.

Intestinal Behçet's Disease with Primary Myelofibrosis Involving Trisomy 8

Behçet's disease (BD) is a disorder characterized by systemic inflammation of multiple organs, including the intestines. Several studies have reported a relationship between myelodysplastic syndrome and BD, and trisomy 8 was frequently seen, especially in intestinal BD. However, the association of BD with primary myelofibrosis (PMF) has not been well documented. A 58-year-old Japanese female was diagnosed with PMF in 2014. The symptoms of PMF resolved with ruxolitinib. However, she developed fever and intestinal perforation due to multiple ulcers in the terminal ileum in 2017. Intestinal perforation recurred 1 month later, and the dose of ruxolitinib was tapered. After discontinuation of ruxolitinib, she presented with recurrent oral aphthous ulcers and uveitis. Subsequently, intestinal perforation recurred, and she was diagnosed with intestinal BD. Trisomy 8 was identified in her peripheral blood. She underwent steroid therapy, azathioprine, and infliximab. This case suggests relationships between PMF, trisomy 8, and BD.

Clinical characteristics of avascular necrosis in patients with Behçet disease: a case series and literature review

Avascular necrosis (AVN), also known as osteonecrosis, is characterized by death of the osteocytes due to inadequate blood supply caused by various mechanisms. The hip is the most common affected joint followed by knee. Incidence of AVN in rheumatic diseases is variable and high corticosteroid (CS) therapy is a known major risk factor for development of AVN. Data on the AVN in Behçet disease (BD) are limited. The purpose of this study is to examine the clinical and treatment characteristics of BD patients with diagnosis of AVN. Retrospective medical records of 337 BD patients were reviewed. Nine BD patients with AVN were detected. The clinical data of these patients with AVN have been reviewed. All patients had MRI of the symptomatic joints compatible with AVN. All of the nine patients who were diagnosed with AVN were male. Median duration of BD was 7 years. Median time between diagnosis of BD and detection of AVN was 3 years (1-16 years). Multiple joints were involved in seven patients. Six patients had bilateral knee AVN. Six patients had vascular BD. The median time interval between initial CS dose and AVN development was 24 months (range = 2-100). The median highest daily CS dose was 64 mg/day (range = 32-80) and median cumulative CS dose prior to AVN was 18 g. All of patients had intravenous pulse steroids. CS treatment, smoking and vascular involvement may predispose to AVN in patients with BD. According to this cohort, AVN in BD frequently tended to be in the knee joint and bilateral.

Inflammatory disorders associated with trisomy 8-myelodysplastic syndromes: French retrospective case-control study

OBJECTIVE

We report cases of myelodysplastic syndrome/myeloproliferative neoplasms (MDS/MPN) with trisomy 8 associated with inflammatory and autoimmune diseases (IADs).

METHOD

Data for 21 patients with trisomy 8-MDS/MPN and IADs were analyzed and compared to 103 patients with trisomy 8-MDS/MPN without IADs.

RESULTS

The median age of MDS/MPN patients with IADs was 67 [59-80]. The IADs were Behçet's-like disease in 11 (52%) patients, inflammatory arthritis in 4 (19%) and Sjögren's syndrome, autoimmune hemolytic anemia, aseptic abscess, periarteritis nodosa, Sweet's syndrome and unclassified vasculitis in one patient each. Overall, 17/21 (81%) patients with IADs received treatment (88% with steroids), with complete and partial response in 7/17 (35%) and 8/17 (47%), respectively. The effect of MDS treatment on IADs could be assessed in seven patients receiving azacytidine: five achieved remission and two partial response. As compared with the 103 trisomy 8-MDS/MPN cases without IADs, those with IADs were more often non-European (P = 0.005) and had poor karyotype (P < 0.001). We found no difference in overall survival or acute myeloid leukemia progression between trisomy 8-associated MDS/MPN with and without IADs.

CONCLUSION

The spectrum of IADs associated with trisomy 8-positive MDS/MPN is dominated by Behçet's-like disease. Steroid therapy is effective, but mostly sparing therapies are necessary. Azacytidine could be an effective alternative.

High Incidence of Gastrointestinal Ulceration and Cytogenetic Aberration of Trisomy 8 as Typical Features of Behçet's Disease Associated with Myelodysplastic Syndrome: A Series of 16 Consecutive Chinese Patients from the Shanghai Behçet's Disease Database and Comparison with the Literature

This study aimed to investigate the characteristics of Chinese patients with Behçet disease (BD) and myelodysplastic syndrome (MDS) and explore the role played by trisomy 8. This was a retrospective study of patients with BD and MDS from the Shanghai Behçet's disease database who were diagnosed between October 2012 and July 2017. There were 805 patients with BD and 16 also had MDS. Trisomy 8 was examined in patients with BD-MDS and some patients with gastrointestinal (GI) BD. Patients with BD and MDS (16/805; 2%) were more likely to be female and older; display fever and intestinal lesions; have lower leukocyte count, hemoglobin, platelet count; and show higher C-reactive protein and erythrocyte sedimentation rate (ESR) than patients with BD without MDS (all P < 0.05). Trisomy 8 was common (81.3%) in patients with BD-MDS. Ulcers in the ileocecal region were more frequently seen in intestinal patients with BD-MDS than in BD without MDS (90.0% versus 48.9%; P = 0.032). GI ulceration is common in patients with BD-MDS. Cytogenetic aberrations, especially trisomy 8, may play a role in the pathogenesis of intestinal involvement in patients with BD-MDS.

The burden of autoimmunity in myelodysplastic syndromes

The clinical history of patients with myelodysplastic syndromes (MDS) is characterised by bone marrow insufficiency as well as by the possible evolution into acute leukaemia. However a number of reports highlight the frequent occurrence of autoimmune manifestations involving different sites and organs. The present review will first describe the clinical pictures most often observed in MDS patients. The actual burden of autoimmunity will be then addressed by focusing on the few available registry studies. Finally, the potential collateral impact of specific treatments for MDS on the evolution of autoimmune disorders will be considered.

Acute Monocytic Leukemia Masquerading Behçet's Disease-Like Illness at Onset in an Elderly Female

A previously healthy 74-year-old Japanese female was hospitalized with fever and high C-reactive protein. She developed palatal herpangina-like aphthous ulcers, localized intestinal wall thickening, terminal ileum ulcers, and an erythematous acneiform rash; thus Behçet's disease-like illness was suspected. Significant peripheral blood acute monocytosis developed during her hospitalization and acute monocytic leukemia (FAB M5b) with normal karyotype was diagnosed. By immunostaining, the infiltrating cells in the skin and the terminal ileum were identified as monocytic leukemic cells. This case exhibited a unique initial presentation of Behçet's disease-like illness associated with acute monocytic leukemia.

Usefulness of Adalimumab for Treating a Case of Intestinal Behçet's Disease With Trisomy 8 Myelodysplastic Syndrome

Behçet's disease (BD) is a systemic vasculitis, while myelodysplastic syndrome (MDS) is a heterogeneous group of clonal hematologic disorders characterized by ineffective hematopoiesis. Some studies suggest a relationship between MDS and BD, especially intestinal BD, and trisomy 8 seems to play an important role in both diseases. There are several reports on patients with BD comorbid with MDS involving trisomy 8 that frequently have intestinal lesions refractory to conventional medical therapies. Tumor necrosis factor (TNF)-α is strongly involved in the pathophysiology of several autoimmune diseases such as rheumatoid arthritis, inflammatory bowel disease, and BD. In addition, TNF-α plays an important role in the pathophysiology of MDS by inhibiting normal hematopoiesis and inducing the programmed cell death of normal total bone marrow cells and normal CD34+ cells. Recent clinical reports demonstrate the favorable effect of TNF-α antagonists in patients with refractory intestinal BD and in those with MDS. We present the case of a patient with intestinal BD and MDS involving trisomy 8 who was successfully treated with adalimumab.

Refractoriness of intestinal Behçet's disease with myelodysplastic syndrome involving trisomy 8 to medical therapies - our case experience and review of the literature

BACKGROUND/AIMS

Gastrointestinal lesions of Behçet's disease (BD) are often refractory to medical therapy and sometimes result in serious comorbidities such as gastrointestinal perforation and massive bleeding. There are several reports of patients with BD comorbid with myelodysplastic syndrome (MDS) involving trisomy 8 that frequently have intestinal lesions refractory to conventional medical therapy. Little is known about the efficacy of infliximab (IFX) for these intestinal lesions.

METHODS

We present 2 cases of intestinal BD with MDS involving trisomy 8 who did not respond to IFX, and review previous reports of BD with MDS involving trisomy 8 concerning their responsiveness to conventional medical therapy.

RESULTS

Among 31 previously reported cases that received medical treatment for BD, 19 (61.3%) showed temporary improvement of the BD symptoms, 9 (29.0%) deteriorated, and 3 (9.7%) showed no change. All of the 9 cases that showed deterioration had intestinal lesions. Our 2 cases failed to respond to IFX, resulting in a poor prognosis.

CONCLUSIONS

IFX might not be effective for improving intestinal BD comorbid with MDS involving trisomy 8. Trisomy 8 is associated with the BD prognosis and refractoriness to conventional medical therapy.

Clinical features of three cases with pulmonary alveolar proteinosis secondary to myelodysplastic syndrome developed during the course of Behçet's disease

We have previously reported that myelodysplastic syndrome (MDS) is the most common underlying disease in cases of secondary pulmonary alveolar proteinosis (PAP). Here, we present 3 MDS cases in which PAP developed during the course of Behçet's disease (BD). All patients carried trisomy 8 in the bone marrow. Chest HRCT scans showed variable distribution of ground glass opacities, but none of the scans showed so called "crazy paving appearance". Two patients with intestinal BD who underwent potent immunosuppressive therapy died of sepsis. These findings demonstrate that PAP secondary to MDS may be occasionally associated with BD.

Acrocyanosis: the Flying Dutchman

Acrocyanosis is symmetric, painless, discoloration of different shades of blue in the distal parts of the body that is marked by symmetry, relative persistence of the skin color changes with aggravation by cold exposure, and frequent association with local hyperhidrosis of hands and feet. Described over a century ago and despite seeming familiarity, it remains a poorly understood condition that shares much in clinical presentation with other conditions characterized by skin color changes in the distal parts of the body. The diagnosis remains mostly clinical, and pathological mechanisms vary suggesting that acrocyanosis may not be a single entity. We performed an extensive literature review to summarize existing knowledge about the demographics, pathology, diagnosis, and treatment of this condition.

Prevalence and prognostic value of cutaneous manifestations in patients with myelodysplastic syndrome

BACKGROUND

Skin manifestations associated with myelodysplastic syndrome (MDS) may reveal bone marrow transformation into acute myeloid leukaemia.

OBJECTIVE

The objective of this study was to assess the prevalence of skin manifestations associated with MDS. In addition, we evaluated the risk of acute myeloid leukaemia transformation associated with skin manifestations.

METHODS

We studied a cohort of 157 patients with primary MDS followed up prospectively for a median of 44 months. Skin lesions were prospectively assessed as part of medical examination every 6 months by a board certified dermatologist. Survival analyses were performed to assess the association between the presence of skin lesions and the risk of acute myeloid leukaemia.

RESULTS

Fifteen patients (9.55%) experienced skin lesions previously reported as associated with MDS. These were neutrophilic dermatosis (7, 4.46%), specific lesions (5, 3.18%), cutaneous vasculitis (2, 1.27%) and Behçet disease (1, 0.63%). Survival analysis showed that the risk of transformation into acute myeloid leukaemia was slightly but not significantly increased in patients with skin lesions as compared with patients without skin lesions with a relative risk of 2.08 (95% CI 0.92-4.67).

CONCLUSION

The prevalence of skin lesions, mostly neutrophilic dermatosis and specific lesions, is relatively high in patients with MDS. There is a trend for a higher risk of transformation into acute myeloid leukaemia in patients with skin lesions.

Periodic fever and erythema nodosum associated with MDS with trisomy 8: report of two cases and review of the literature

We report two cases of myelodysplastic syndrome (MDS) with trisomy 8 who had periodic fever and erythema nodosum (EN). A 74-year-old man showed periodic fever and EN. A diagnosis of MDS with trisomy 8 was made, and he was successfully treated with prednisolone (PSL). A 71-year-old man presented with intermittent fever, EN, and recurrent elevation of myogenic enzymes. Despite sustained inflammation, laboratory tests showed macrocytic anemia and thrombocytopenia. Marrow aspiration showed MDS with the chromosomal abnormality trisomy 8. He was successfully treated with PSL without repeated transient fever and elevation of creatine kinase. The results of a literature review of 35 cases of MDS with trisomy 8 and Behçet's disease-like symptoms, such as EN, oral ulcer and intestinal ulcer, suggest that the disease entity of "trisomy 8 syndrome" may be considered, and that it is an important differential diagnosis of periodic fever and EN.

Constitutional trisomy 8 and Behçet syndrome

The characteristic clinical features of constitutional trisomy 8 include varying degrees of developmental delay, joint contractures and deep palmar and plantar creases. There is an established literature, which describes features of Behçet syndrome occurring in phenotypically normal individuals with myelodysplastic syndromes and trisomy 8 in their bone marrow. In this article, we describe four patients with constitutional trisomy 8, all with varying clinical phenotypes, who developed features of Behçet, in particular but not exclusively mucocutaneous ulceration. In addition, we examined gene copy numbers of the variable-number neutrophil defensin genes DEFA1A3 in one of the cases (case 1) and her parents, together with 14 cases of Behçet syndrome in comparison with 121 normal controls. The gene copy number was highest in case 1 (copy number 14) and was also increased in her parents (both copy number 9). However the mean copy number for DEFA1A3 among the 14 Behçet syndrome patients was actually lower (5.1) than among the controls (mean of 6.8 copies). Thus, we conclude that patients with constitutional trisomy 8 and those with trisomy 8 confined to the bone marrow are both at increased risk of developing features of Behçet syndrome. The mechanism may relate to increased chromosome 8 gene dosage with further analysis of candidate genes on chromosome 8 required.
