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

Refractory Intestinal Behçet-Like Disease Associated with Trisomy 8 Myelodysplastic Syndrome Resolved by Parenteral Nutrition

Intestinal Behçet disease (BD), associated with myelodysplastic syndrome (MDS), is often refractory to treatment. An 80-year-old man with trisomy 8 MDS (refractory anemia) developed intermittent fever. Despite investigations to exclude infectious disease, autoimmune disease, and malignancy as the cause of the fever, the etiology could not be determined. A colonoscopy revealed several shallow round ulcers in the ileocecal region and ascending colon, and the biopsy specimens showed nonspecific inflammation. Thereafter, the patient experienced abdominal pain and diarrhea. Other than an oral aphthous ulcer, the patient did not show symptoms to meet the diagnostic criteria for BD. The patient was diagnosed with intestinal ulcers (intestinal BD-like disease) with MDS and trisomy 8. After treatment failure with 5-aminosalicylic acid, steroid, colchicine, and azacitidine, cerebral infarction occurred. Eating was difficult because of the patient's impaired consciousness; hence, total parenteral nutrition (TPN) was commenced. The fever and abdominal symptoms improved with bowel rest over approximately 1 month. Small amounts of food were orally administered to the patient following recovery from the after-effects of the cerebral infarction, but diarrhea and fever repeatedly flared up. Therefore, TPN was continued at home. The patient has not experienced any further intestinal BD symptoms for approximately 1 year with bowel rest. Nutritional therapy, including bowel rest, may be an effective treatment option for intestinal BD with MDS, and might be used as an induction therapy of remission or a supportive therapy for other treatments.

Chromosomal abnormalities related to fever of unknown origin in a Chinese pediatric cohort and literature review

BACKGROUND

Fever of unknown origin (FUO) has been difficult to diagnose in pediatric clinical practice. With the gradual change in the disease spectrum, genetic factors have received increasing attention. Limited studies have shown an association between FUO and chromosomal abnormalities. In this study, we investigated the clinical and genetic characteristics of patients with FUO presenting with chromosomal abnormalities in a Chinese pediatric cohort.

RESULTS

Chromosomal abnormalities were detected in 5.5% (8/145) of the patients with FUO. Six patients with inflammatory fever presented with pharyngitis/amygdalitis (4/6), oral aphthous ulcer (2/6), digestive symptoms (3/6), developmental delay (4/6) and elevated C-reactive protein levels (6/6) during fever. These patients were often considered to have systemic inflammatory diseases, such as Behcet's disease or systemic juvenile idiopathic arthritis. Trisomy 8, 7q11.23 dup, 3p26.3-p26.1 del/17q12 dup, 22q11.21 del, and 6q23.3-q24.1 del were identified in patients with inflammatory fever. The TNFAIP3 gene was included in the 6q23.3-q24.1 deletion fragment. Two patients with central fever were characterized by facial anomalies, developmental delay, seizures and no response to antipyretic drugs and were identified as carrying the de novo 18q22.3-q23 del. By performing a literature review, an additional 19 patients who had FUO and chromosomal abnormalities were identified. Trisomy 8, 6q23.2-q24.3 del and 18q22.3-q23 del were reported to present as fever, similar to the findings of our study.

CONCLUSIONS

We emphasized the important role of detecting chromosomal abnormalities in patients with FUO, especially in patients with systemic inflammatory manifestations or developmental delay. Identifying chromosomal abnormalities may change the diagnosis and management of patients with FUO.

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.

Mimicker of necrotising fasciitis with systemic inflammatory response syndrome: recurrent necrotising Sweet's syndrome associated with chronic myelogenous leukaemia

A 73-year-old man presented with severe right upper quadrant abdominal pain, overlying erythema, hypotension and fever. CT scan revealed fasciitis and myositis of the right rectus abdominis muscle with subcutaneous inflammation involving the fasciae and muscle. Laboratory studies showed extreme leucocytosis. The combination of his symptoms, CT findings and laboratory results suggested necrotising fasciitis with systemic inflammatory response syndrome. Subsequent negative cultures on skin and muscle biopsy led to a diagnosis of necrotising neutrophilic panniculitis. Recurrent episodes of fever, and abdominal and buttocks pain at various sites, suggested an underlying haematological condition. Bone marrow biopsy and genetic analysis revealed chronic myelogenous leukaemia. The patient's symptoms of Sweet's syndrome resolved with glucocorticoid treatment and did not recur after starting treatment with a tyrosine kinase inhibitor.

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.

Successful treatment by azacitidine therapy of intestinal Behçet's disease associated with myelodysplastic syndrome

Myelodysplastic syndrome (MDS) is a heterogeneous group of clonal hematopoietic stem cell diseases. It has been reported that several autoimmune diseases are associated with MDS. Recently, the co-occurrence of MDS with trisomy 8 and rare disorders of the immune system, such as Behçet's disease (BD), has been described. Prognosis in the older-onset group of MDS-associated BD is unfavorable. Here, we report a case of MDS-associated intestinal BD treated successfully by azacitidine therapy. A 59-year-old Japanese male suffering from recurrent high fever, melena, and oral and genital ulcerations was diagnosed with MDS with trisomy 8 and intestinal BD by endoscopic and bone marrow examinations. Immunosuppressive therapies, including infliximab, were ineffective. Due to his severe emphysema, the patient was considered ineligible for stem cell transplantation, and azacitidine therapy was initiated. With the exception of fever, the symptoms of intestinal BD improved, and severe malnutrition and anemia were ameliorated. Fluorescence in situ hybridization analyses of the bone marrow before the eighth cycle revealed that the trisomy 8 had not decreased. To our knowledge, this is the first report of azacitidine therapy for MDS-associated BD. We suggest that azacitidine may control intestinal BD by mechanisms other than those responsible for its effect in MDS.
