Abstract

Association between inflammatory bowel disease (IBD) and myelodysplastic syndrome, in particular aplastic anaemia was reported with possible share a common immune dysfunction pathway. Extra intestinal manifestations of IBD are also common and usually related to the activity of IBD. We report a case of active ulcerative colitis associated with aplastic anaemia, dermatological and thromboembolic extra intestinal manifestations.

Key words

aplastic anaemia, immune dysfunction pathway, inflammatory bowel disease

Introduction

Ulcerative colitis (UC) is an autoimmune disease that mainly affects the mucosa of the colon. Haematological affection is commonly associated with UC.It can be due to multiple causes: blood loss, malabsorption, chronicity of UC, sepsis, associated myelodysplastic syndromes, or hemolysis [1]. There is a clinical association between inflammatory bowel disease (IBD) and myelodysplastic syndrome, maybe they share an immune dysfunction and impairment of T-lymphocytes activities [2]. Extra intestinal manifestations of IBD are usually accompanied with activity of IBD.

Case presentation

We present a case of male patient 35 years old, complained of bloody diarrhoea more than 6 times / day. Patient has been diagnosed as ulcerative colitis for four years. On examination he was pale, average built, with slight diminution of vision. There was area of Pyoderma gangrenosum on extensor side of his right thigh. Patient had history of deep venous thrombosis for which he received warfarin for 6 months. His current therapy also included mesalamine 3 grams/day, 300 mg hydrocortisone was started after his admission in Mansoura specialized medical hospital. Abdomen ultrasound and CT were free.

His laboratory testing showed: Complete Blood Count: haemoglobin was 9.2 gm/dl, MCV: 77 fl, Platelets: 42 /cmm3, WBCs:3 /cmm3, Reticulocyte count:1.2%, INR: 1, ferritin: 11.5 ng/ml, LDH :265 U/I (100-190), Creatinine: 0.9 mg/dl, uric acid: 4.8, Urinalysis: NAD. Serum calcium ionized 0.83 mmol/L(1.15-1.32), Serum albumin: 3.8 g/dl, serum bilirubin : 0.8 mg/dl (direct) 0.2 mg/dl, ALT: 13 mg/dl, AST: 13 mg/dl, alkaline phosphatase :228 U/L HBs-Ag, HBc -Ab IgM, HCV Ab, HIV Ab: all are –ve, CMV IgM -ve, Quantiferon TB:-ve. ESR: 30, CRP: 60, faecal calprotectin: 1000 ug/g, Coomb’s (direct) positive, (indirect) negative, ANA –ve, Prothrombin gene mutation: normal, Factor V Leiden: heterogenous gene mutation was detected.

CBC was repeated serially due to pancytopenia. Haematological consultation advised bone marrow biopsy that showed marked hypo cellular bone marrow with 5-10% cellularity, the erythroid series is represented by few megakaryocytes and reduced myeloid series, with no detected abnormal deposits; picture suggestive of aplastic anaemia. He was advised to start Eltrombopag daily and epoetin alpha weekly with frequent substitution by transfusion of packed RBCs and platelets. Anticoagulant was started by recombinant hirudin 15 mg sc/12 hours. There was problem related to stating azathioprine as immune modulator due to his pancytopenia yet, anti TNF infliximab was started after 2 weeks of his admission as well as cyclosporine by dose 300 mg daily. He showed improvement concerning the pyoderma gangrenosum and the activity of ulcerative colitis (Table 1).

During his admission patient complained of more diminution of vision. Ophthalmological consultation ordered fluorescein angiography of the right eye that showed dilated capillaries of optic disc indicating disc edema and areas of haemorrhage giving impression of non-ischemic central retinal vein occlusion with diffuse maculopathy. As for the left eye there was mild retinal haemorrhage (impending vein occlusion) with increased central macular thickness and neurosensory detachment. He was advised to have frequent laser photocoagulation sessions that showed slight improvement (Figure 1).

Discussion and conclusion

Ulcerative colitis (UC) is an inflammatory bowel disease of unknown etiology that mainly affects the mucosa of the colon due to immune reaction and immunogenetic factors. Haematological affection is commonly associated with UC.It can be due to multiple causes: blood loss, malabsorption, chronicity of UC, sepsis, associated myelodysplastic syndromes, or haemolysis [1]. Several investigators have suggested a clinical association between inflammatory bowel disease (IBD) and myelodysplastic syndrome, may be they share an immune dysfunction and impairment of T-lymphocytes activities, that contribute to peripheral blood pancytopenia and bone marrow hypoplasia [2-5].

Aplastic anaemia (AA) is a clinical syndrome with failure of bone marrow hematopoietic synthesis. The symptoms of AA include bone marrow hypoplasia, pancytopenia and anaemia, bleeding, and infection syndrome. The possible pathogenic elements of AA related to IBD case include drugs like mesalazine and sulfasalazine, chemicals, radiation, immune dysfunction, and hereditary reasons [6,7]. Mesalazine induced severe AA in patients with UC has also been reported after the treatment by 4 months [8]. In the presented case, the AA was diagnosed after UC by 4 years. When mesalamine treatment was stopped and started antiTNF the AA was still present.

Aplastic anaemia relation to IBD may be considered a matter of association rather than complication or extra intestinal manifestation making the treatment of such cases a big challenge. The association of AA is more common with UC than CD, yet six cases of CD were reported associated with AA [9]. It was reported that in more than half of the cases there is a favourable response to treatment with immunosuppressants for patients with UC and AA due to the common immune pathogenesis [10]. Immunosuppressants as cyclosporine acts directly by suppressing lymphokine production by T cells and it shows a good response in a case of UC associated AA[11]. However, it does not show improvement in our case despite its use for about 6 months. This supports the idea of considering AA to be associated with UC rather than to be supposed as an extra intestinal manifestation of IBD. So the next step in the management of AA in our case may be bone marrow transplant (BMT) that may show success .This can be the same as it was reported in a case of AA that was associated with UC and failed cyclosporine treatment so BMT was done [12].

The ophthalmological manifestation in this case was in the form of central retinal vein occlusion. It can be mostly attributed to the hypercoagulable complication of the active UC. Thromboembolic events resulting from hypercoagulable state in patients with IBD can lead to pulmonary embolism. Thrombosis has been reported in 1.8% of patients with UC due to inflammation, fluid depletion, hospital immobilization, surgery, steroid therapy, and use of central venous catheters. Some proinflammatory cytokines have thrombogenic effect such as interleukin-6 [13-15]. Therefore, our patient continued anticoagulant therapy. Recombinant hirudin was used to avoid heparin induced thrombocytopenia.

Our case of UC was complicated with pyoderma gangrenosum, which highlights the dermatological complications of UC. Skin involvement has been described in 10% to 15% of patients with IBD [15]. Maybe either erythema nodosum or pyoderma gangrenosum. Lesions are found typically on the extensor surfaces of the extremities, and usually resolves with treatment of the underlying IBD [17] the same that happened in our case after starting the antiTNF.

This can be the only case mentioned in literature that combine the extra intestinal manifestation of UC in the form of pyoderma gangrenosum and thromboembolic manifestations together with the association of AA.
