Hungarian Immunology - 2005;4(01)

[The two archetypes of inflammatory bowel diseases, Crohn’s disease (CD) and ulcerative colitis (UC) have a considerably high prevalence and chronic morbidity, and thereby a striking public health relevance amongst the maladies involving the gastrointestinal tract. Unveiling their pathogenesis can be the key for the development of successful therapeutic approaches. Our view of these diseases has undergone radical changes in the past few years, and the latest discoveries have shed new light upon their pathomechanism. A multifactorial view is appropriate when explaining their pathogenesis, although certain factors are seemingly of particular importance.]

SZÁNTÓ Sándor, GONDA Andrea, MIKECZ Katalin, GLANT Tibor, SZEKANECZ Zoltán

[Animal models of experimental arthritis can be used to understand pathophysiology of the arthritic processes in patients and provide opportunity to develop new therapeutic approaches. The animal models can be divided into different categories based on the pathomechanism of the model and on the features that resemble human inflammatory joint diseases. This review provides an overview of the most widely used types of experimental arthritis models emphasizing their advantages and limitations in the basic arthritis research.]

CSIKI Zoltán, GALUSKA László, GARAI Ildikó, SZABÓ Nóra, GALAJDA Zoltán, VARGA József, ZEHER Margit

[INTRODUCTION - In patients presenting with isolated tissue perfusion disturbance without large vessel involvement the examination of hand microcirculation is of major importance. In our study we present the results of three examination methods used for hand perfusion monitoring which measure the tissue microcirculation in different depths. PATIENTS AND METHODS - We examined 58 primary Raynaud's patients using capillary microscopy, laser doppler perfusion imaging and hand perfusion scintigraphy with Tc-99m-DTPA. From our patients 38 were smokers, 42 patients frequently suffered from headache. For the validation of our laser Doppler results we involved into the study also 16 non-smoker healthy volunteers. For the standardisation of the results the studies were performed in a climatised room. During the laser examination we performed and analysed also the post-occlusion hyperaemia test. RESULTS - In the majority of our patients no morphological alterations were found with capillary microscopy. In primary Raynaud’s patients the perfusion values measured with laser-Doppler scanner in basic condition were significantly lower both in fingers’ and palm’s regions compared to healthy controls. In the primary Raynaud’s group the smokers had significantly lower hyperaemic response than the non-smokers and we measured also significantly lower FPR (finger-to-palm ratio) values with hand perfusion scintigraphy. Both with laser doppler imaging and hand perfusion scintigraphy there was no difference between the values measured in patients with or without headache. CONCLUSIONS - We consider of benefit the functional examination of hand circulation in all diseases involving the hand microcirculation.]

[Immune-dysfunctions in patients with Hodgkin’s lymphoma being in a long lasting complete remission]

ALEKSZA Magdolna, KERESZTES Katalin, BARÁTH Sándor, SIPKA Sándor, ILLÉS Árpád

[OBJECTIVES - Immunosuppression has long been known to be associated with Hodgkin’s lymphoma. The authors report on immunologic abnormalities with special focus on cellular immunity in patients with Hodgkin’s disease in complete remission. METHODS - We determined the proportion of the lymphocytes subpopulations, activated T cells, CD4+/CD25+ suppressor T cell population and intracytoplasmic cytokines by flow cytometry. The soluble cytokines were measured by classical ELISA technique. RESULTS - Based on lymphocyte cell surface antigen expression the subpopulations were as described in the literature, however a unique elevation of CD4+/CD25+ cell fraction was detected. The decreased amount of IFN-γ in the serum suggest Th2 dominance, but reduced intracellular IL-4 production in both CD4+ and CD8+ cells results from Th1 dominance. These results somewhat contrary but can not be completely compared as in vivo and in vitro techniques used for the analysis are not identical. However a constant elevation concentration and expression of IL-10 and TGF-β is observed. CONCLUSION - These alterations may reflect the existence of an immunosuppressive state also in the peripheral blood of Hodgkin’s lymphoma patients not only in the lymph nodes.]

[CT enteroclysis in small bowel Crohn’s disease]

TÓTH Géza, MAGYAR Péter

[PURPOSE - The aim of this paper is to demonstrate morphological changes of Crohn’s disease observed by CT enteroclysis and also to evaluate the role of the method in the diagnosis and the follow up of patients with known or suspected Crohn’s disease. PATIENTS AND METHODS - We evaluated retrospectively 50 typical cases who were examined earlier. Crohns’s disease was diagnosed in 42 patients before CT enteroclysis. Histological confirmation was available in 36 cases after colonoscopy and in six cases after surgery. In eight patients had a high suspicion of the disease, histological examination was not performed. CT enteroclysis findings were read by two radiologist independently and results were compared. RESULTS - CT enteroclysis showed typical signs of Crohn’s disease in all patients. Different degree of wall thickening was seen in all cases, pathological enhancement of small bowel wall (in cases 35), multilayered appearance (n=29), fibrofatty proliferation (n=33), enlarged lymph nodes (n=37), entero-enteric fistula (n=6), entero-cutan fistula n (=5), mesenteric abscess (n=5) was found. CONCLUSION - CT enteroclysis is an accurate method to detect mural and extramural abnormalities in patients with Crohn’s disease. CT enteroclysis proved highly accurate in detecting small bowel involvement and it also provides an estimation of clinical activity of the disease. CT enetroclysis can be considered as the first imaging method in patients with clinical signs of Crohn’s diseases and also in the follow up of patients with known disease.]

[Effective adalimumab treatment of a steroid-dependent Crohns’ disease patient suffering from general, abdominal and joint symptoms of multiple etiology]

[The 69-year-old male patient had been suffering from periodically relapsing rheumatological symptoms involving variable localisations (knee, ankle, MTP, sternoclavicular and hip joint) since 1964. On the basis of his joint symptoms, load-independent lower back pain, sacroileitis, recurrent iridocyclitis, urethroprostatitis and oral aphtous lesions, Reiter disease was diagnosed in 2000. The patient had Lyme-disease (confirmed Borrelia burgdorferi seropositivity) with peripheral facial paresis in 2003. The patients joint problems relapsed in 2006, accompanied by diarrhoea and fever, independent of any infecions. The possibility of IBD could not be confirmed either by macroscopic examination using colonoscopy or hystology. The patient was admitted to our department in March 2008 for the first time, presenting again with joint pain and disability of gait, 7-8 bowel movements a day, and fever. Taken together the clinical symptoms, the typical radiological findings and HLA-B27 positivity, Bechterew disease was diagnosed. Colonoscopy performed because of diarrhea revealed multiple segmental aphtoid lesions and irregular ulcers, suggesting Crohn disease that was confirmed by histology (cryptal abscess formation and microgranulomas). Sulfasalazin, 5-ASA, and other NSAIDs applied to treat rheumatological symptoms could not eliminate either the gastrointestinal or the rheumatological symptoms of the patient, which necessitated regular steroid therapy. Because of the patient’s steroid dependency, and considering his rheumatological symptoms, in June 2008 he was treated with adalimumab (ADA) induction therapy (80-40-40 mg s.c.). In two weeks, his gastrointestinal as well as extraintestinal symptoms substantially improved, and completely diminished through the course of maintenance ADA therapy (40mg weekly). The patient is still asymptomatic and is excercising (jogging) regularly.]

[Tension-type headache in ulcerative colitis]

TAJTI Jr. János, LÁTOS Melinda, ÁBRAHÁM Szabolcs, SIMONKA Zsolt, PASZT Attila, LÁZÁR György

[Background and purpose - Tension-type headache is a very common disease with a high socio-economic impact as its lifetime prevalence is 30-78% in the general population. The incidence of inflammatory bowel diseases is continuously rising. Limited data are accessible on quality of life in patients with surgically treated ulcerative colitis. The aim of our study is to examine quality of life, concerning headache, among patients who had undergone surgery due to ulcerative colitis. Methods - Between 1 January 2005 and 1 March 2016, surgery was performed due to ulcerative colitis in 75 patients. During this retrospective analysis the average duration of the follow-up was 46 (1-124) months. The pre-sence of headache was evaluated by the use of Brief Illness Perception and Headache Questionnaires. Results - Among the primary headache disorders (n=27), tension-type headache occurred in 19 (70.4%) cases, and 8 (29.6%) patients had migraine (without aura). Among tension-type headache cases 17 (89.5%) patients experienced episodic form and 2 (10.5%) suffered from chronic form. Patients with headache had obtained a significantly higher score on Brief Illness Perception Questionnaire. Conclusions - According to our study tension-type headache is common among patients with ulcerative colitis. This observation raises the question whether stress plays role in the pathogenesis of both diseases, which influences and worsens considerably quality of life. Neurological examination, psychological and psychiatric guidance are worth considering in patients with ulcerative colitis.]

[THE GENETICS OF INFLAMMATORY BOWEL DISEASE]

LAKATOS Péter László, LAKATOS László

[The pathogenesis of inflammatory bowel disease is only partly understood; various environmental and host factors (e.g., genetic, epithelial, immune and non-immune) are involved. It is a multifactorial polygenic disease probably with genetic heterogeneity; some genes confer susceptibility to IBD in general, while others specifically increase the risk of ulcerative colitis or Crohn's disease or affect location (localized or extensive) and/or behaviour (e.g., mild, severe, aggressive). This review presents recent advances in the genetics of inflammatory bowel disease including chromosome segments newly recognized to be involved in inflammatory bowel disease as well as the role of NOD2/CARD15, SLC22A4/A5 and DLG5. The increasing genetic information provides, for the time being, a better understanding of the pathogenesis of the disease thus setting a basis for potential targets for therapeutic intervention. In the future, however, genetics may also help in refining the diagnosis or predicting disease course.]

[Isolated anal form of Crohn’s disease with an extensive perianal septic complication]

DOBÓ István, JÓSVAY János

[INTRODUCTION - Perianal manifestations of Crohn’s disease are common. Treatment of advanced complications like strictures and incontinence may require a radical surgical intervention. We present a case of an extremely rare manifestation of Crohn’s disease. The disease localized exclusively to the anal canal for more than twenty years was complicated by an extensive perianal septic lesion. Besides our own surgical strategy, we discuss in detail other therapeutic options for perianal septic complications of Crohn’s disease. CASE REPORT - During 16 years of disease course the perianal process of the 34 year old female patient caused sphincter destruction and incontinence, and furthermore resulted in a chronic septic state by fistulous tracts involving the whole perineo-gluteal region. Following rectal extirpation, we performed a radical excision and a reconstructive operation using musculo- cutaneous/fascio-cutaneous advancement flaps. The final result of multiple operations of two years’ duration was functionally and aesthetically excellent. CONCLUSION - Fistulous tracts of perianal Crohn’s disease destructing widely their surroundings can only be cured by the radical excision of involved tissues. Extremely large consequent defects can also be covered with proper functional results by methods applying healthy tissues of good loadability i.e. musculocutaneous/ fascio-cutaneous advancement flaps.]
