Current practice in the diagnosis and management of IBD-associated anaemia and iron deficiency in Germany: The German AnaemIBD Study

Background/aimAnaemia is a common complication in inflammatory bowel disease (IBD), frequently resulting from iron deficiency. IBD guidelines advocate intravenous iron administration although some patients respond to oral supplementation. This non-interventional study investigates the current status of anaemia management in German IBD patients.MethodsBaseline data on pre-study treatment for anaemia were retrospectively analysed in IBD patients with anaemia participating in a prospective trial of the efficacy and safety of ferric carboxymaltose. Data were collected from 55 German gastroenterological centres up to August 2010. Subjects had received care at their centre for at least 12 months prior to baseline.Results193 cases of IBD-associated anaemia (115 Crohn's disease, 77 ulcerative colitis) were analysed (mean age: 39 years (18–83), 79 (41%) males). Anaemia and iron status were usually assessed by haemoglobin (100%), serum ferritin (97%), and transferrin saturation (82%). In the previous 6 months, only 84 patients (43.5%) had been treated for anaemia: 47 (56%) with oral iron, 13 (15%) parenteral iron, 16 (19%) oral plus parenteral iron and 8 (10%) transfusions. No patients received erythropoietin stimulating agents.ConclusionAlthough intravenous iron supplementation is recommended in IBD patients, current German practice still relies on oral therapy, even in severe anaemia. The high incidence of severe anaemia in this cohort reflects inadequate iron replacement and status monitoring. While the proportion of IBD patients with inadequately treated anaemia/iron deficiency is unknown, greater awareness of existing guidelines for iron deficiency management in IBD patients appears necessary.     

Course and characteristics of anaemia in patients with rheumatoid arthritis of recent onset.

OBJECTIVE: To describe the incidence, cause, and course of anaemia in rheumatoid arthritis (RA). METHODS: Medical records of 225 patients who received a diagnosis of RA between 1990 and 1992 were reviewed longitudinally for mention of anaemia. Anaemia was classified as anaemia of chronic disease if ferritin concentrations reflected adequate body iron stores. Among iron depleted anaemic patients, iron deficiency anaemia was identified using the response to iron supplementation. RESULTS: Anaemia developed in 64% of the patients, mostly within 18 months of follow up, but disappeared again in 54% of those patients. The prevalence of anaemia varied from 39% to 53% throughout follow up. Iron depletion was found in 38% of anaemic patients; 40% of them did not recover from their anaemia after iron supplementation and were classified as having anaemia of chronic disease. Anaemia of chronic disease thus caused 77% and iron deficiency anaemia 23% of observed anaemia. Recovery from anaemia occurred in 42% of the patients with anaemia of chronic disease and in 72% of iron depleted patients after iron supplementation. Anaemic patients, particularly those with anaemia of chronic disease, had a significantly greater number of the American College of Rheumatism criteria for RA, significantly more erosive joint damage, and significantly increased concentrations of serum rheumatoid factor than patients without anaemia. CONCLUSION: Anaemia appeared as a frequent and dynamic manifestation. Recovery and recurrence of anaemia was observed throughout follow up, leading to a longstanding and relatively high prevalence of the condition. Iron deficiency was diagnosed frequently and follow up revealed a considerable overlap with anaemia of chronic disease, making this the most important cause of anaemia in RA. Recovery from anaemia occurred more frequently in iron depleted anaemic patients than in those with anaemia of chronic disease. Anaemic patients, particularly those with anaemia of chronic disease, seemed to have a more serious course of their RA compared with non-anaemic patients.     

Prevalence of anaemia in inflammatory bowel disease in Switzerland: A cross-sectional study in patients from private practices and university hospitals

BackgroundAnaemia represents a common complication of inflammatory bowel disease (IBD). Most studies on anaemia in IBD patients have been performed in tertiary referral centres (RC) and data from gastroenterologic practices (GP) are lacking. We investigated the frequency and severity of anaemia in IBD patients from tertiary referral centres and gastroenterologic practices compared to the general population.MethodsData were acquired from patients included in the Swiss IBD Cohort Study. IBD activity was evaluated by CDAI and modified Truelove and Witts severity index (MTWSI). Anaemia was defined as haemoglobin ≤ 120 g/L in women and ≤ 130 g/L in men.Results125 patients from RC (66 with Crohn's disease (CD) and 59 with ulcerative colitis (UC)) and 116 patients from GP (71 CD and 45 UC) were included and compared to 6074 blood donors. Anaemia was found in 21.2% (51/241) of the IBD patients and more frequently in patients from RC as compared to GP and healthy controls (28.8% vs. 12.9% vs. 3.4%; P < 0.01). IBD patients from RC suffered more frequently from active disease compared to IBD patients in GP (36% vs. 23%, P = 0.032). Supplementation therapy (iron, vitamine B12, folic acid) was performed in 40% of anaemic IBD patients in GP as compared to 43% in RC.ConclusionsAnaemia is a common complication in patients with IBD and significantly more prevalent in patients from referral centres as compared to patients from gastroenterologic practices. Physicians treating IBD patients should pay attention to the presence of anaemia and ensure sufficient supplementation therapy.     

The use of sirolimus (rapamycin) in the management of refractory inflammatory bowel disease in children

BackgroundManagement of refractory inflammatory bowel disease (IBD) in children is challenging and once response to conventional medical therapy deviates from the expected, options are often limited. Sirolimus is commonly used in post-transplantation management and is used sparsely as rescue therapy in refractory Crohn's disease. In the present study, we report the efficacy of sirolimus as an adjuvant immunosuppressive therapy in a retrospective case review of a selected group of IBD children who were refractory to the conventional treatments.MethodsMedical records of children with refractory IBD unresponsive to conventional therapy and started on sirolimus between 2006 and 2012 were retrospectively reviewed. Clinical response, through Pediatric Ulcerative Colitis Activity Index (PUCAI) and Pediatric Crohn's Disease Activity Index (PCDAI), as well as intestinal inflammation, through specific histological scores, was evaluated.ResultsThe records of 14 patients were analyzed. Eleven of them had ulcerative colitis (UC) and 3 Crohn's disease (CD); mean age at diagnosis was 9.1 years (standard deviation 3.8). Of UC patients, 5 (45%) achieved clinical remission and 2 (18%) showed clinical response. All CD patients went into clinical remission. Mucosal healing was achieved by 5 children (45%) with UC and 2 (67%) with CD patients. One child with ulcerative colitis was weaned off adalimumab, while 2 children with CD were weaned off prednisolone and methotrexate successfully.ConclusionOur data provide evidence that sirolimus seems to be effective as rescue therapy in a subgroup of children with severe IBD refractory to conventional therapies by inducing both clinical remission and mucosal healing.     

Crohn's-like clinical and pathological manifestations of giant inflammatory polyposis in IBD: A potential diagnostic pitfall

Background & aimsGiant inflammatory polyposis (GIP), characterized by mass-like agglomerations of inflammatory polyps, is a rare complication of inflammatory bowel disease (IBD). We reviewed a series of cases of GIP to determine its diagnostic impact on the clinical and pathologic distinction between ulcerative colitis (UC) and colonic Crohn's disease (CD).MethodsAll colons with GIP resected over a 13-year period were identified prospectively and the corresponding clinical and pathologic records were reviewed.ResultsTwelve cases of GIP were identified, accounting for 0.8% of colectomies for IBD during the same time interval. Preoperatively, 6 (50%) patients were diagnosed with UC, 2 (17%) with CD and 4 (33%) with indeterminate colitis (IC). Postoperatively, 6 of the diagnoses (50%) were revised based on strict histopathologic criteria: all 4 diagnoses of IC to UC, one diagnosis of CD to UC, and one diagnosis of UC to CD, for a total of 10 diagnoses of UC (83%) and two of CD (17%). Significantly, 7 of 10 cases with postoperative diagnoses of UC (70%) had Crohn's-like transmural inflammation exclusively within the polyposis segments attributed to fecal entrapment and stasis and accounting for the Crohn's-like clinical complications in these cases.ConclusionsThis case series of GIP, the largest reported from a single center, highlights the high rate of Crohn's-like clinical and pathological manifestations of GIP and their potential to confound the accurate classification of patients with IBD. A diagnosis of UC should not be amended to CD based on the findings of the polyposis segment alone.     

Treatment of anaemia in inflammatory bowel disease with iron sucrose

Background: Inflammatory bowel disease (IBD)‐associated anaemia usually responds to intravenous iron. If not, additive treatment with erythropoietin has been proposed. The objective of the present retrospective study was to evaluate the effectiveness of treatment with iron sucrose alone. Methods: Sixty‐one patients with IBD and anaemia (average haemoglobin 97?g/L) were treated with iron sucrose (iron dose 1.4?±?0.5?g). The indications for iron sucrose were poor response and/or intolerance to oral iron. Treatment response was defined as an increase in haemoglobin of ≥20?g/L or to normal haemoglobin levels (≥120?g/L). Two independent investigators retrospectively assessed laboratory variables, clinical findings, and concomitant medication. Results: Two patients were transferred to other hospitals after treatment and therefore could not be evaluated. Fifty‐four of the remaining 59 patients (91%) responded within 12 weeks. Sixty percent of the patients had responded within 8 weeks. Five patients had no or only a partial response to iron sucrose of which three had prolonged gastrointestinal blood losses. Eight patients with normal or elevated levels of ferritin could be considered to have anaemia of chronic disease, and all of them responded to iron sucrose. During a follow‐up period of 117?±?85 (4–291) (mean?±?s (standard deviation) (range)) weeks 19 patients (32%) needed at least one second course of iron sucrose because of recurrent disease. Conclusions: Anaemia associated with IBD can be successfully treated with intravenously administered iron sucrose, provided that bowel inflammation is treated adequately and enough iron is given. Treatment with iron sucrose is safe. Follow‐up of haemoglobin and iron parameters to avoid further iron deficiency anaemia is recommended.     

Helicobacter pylori and Iron Deficiency Anaemia in Children

Background: Both iron deficiency anaemia and Helicobacter pylori infection are rare in developed countries. A possible connection has been suggested between these two diseases and our aim was to define the clinical picture and to study the effect of bacterial eradication in H. pylori colonized children with severe anaemia. Methods: Eight children with iron deficiency anaemia refractory to iron supplementation were examined with gastroscopy because of suspicion of H. pylori infection. Anaemia was treated with oral ferrous sulphate. Two patients needed blood transfusions. Eradication therapy was given either with combination of colloidal bismuth subcitrate and metronidazole or with omeprazole, clarithromycin and amoxycillin. Eradication was confirmed by urea breath test 4 weeks post-treatment. Results:H. pylori infection was confirmed histologically and microbiologically in all children, who also presented with chronic, active gastritis. Bacteria were successfully eradicated in 7/8 patients. Correction of haemoglobin values was observed post-treatment, iron stores still being deficient at control in 4/8 children. Conclusions: Our results suggest that H. pylori might have a role in causing iron deficiency anaemia in school-age children. Screening for H. pylori should be extended to cover those patients with other clinical manifestations than symptoms from gastrointestinal tract.     

Iron treatment and inflammatory bowel disease: What happens in real practice?

Background and aimsIron deficiency anaemia (IDA), the most common extra-intestinal complication of inflammatory bowel disease (IBD), negatively impacts quality of life. We audited the recent practice of anaemia treatment in an unselected IBD population.MethodsA questionnaire was distributed to adult IBD outpatients in a university hospital to assess the form and frequency of iron prescribed, duration of use, side effects, and completion of therapy. The efficacy of treatment was determined by the resolution of anaemia and change in haemoglobin from baseline.ResultsOf 87 IBD patients (60 patients with Crohn's disease, 25 with ulcerative colitis, 2 with microscopic colitis), 85 received various dosing regimens of iron tablets; 15 patients also received IV iron. Side effects were reported in 43 (51%) patients, with no clear relationship to dose prescribed and 26 (32%) patients were unable to complete the intended course. Only 36 (42%) patients completed the course of oral iron without side effects and in these patients, haemoglobin normalised in about 30%. Their median haemoglobin change was 12.5 (5.3–23.5) g/l. The median duration of treatment in those without side effects was 4.5 months, and in those with adverse effects was 2 months. Only one adverse effect was reported for IV iron.ConclusionsTreatment with oral iron results in failure to control anaemia in 2 out of 3 IBD patients, which is likely in part to be due to the side effects reported by over half of patients. Patients failing to tolerate or adequately respond to therapy should be offered alternative treatment.     

Anaemia in rheumatoid arthritis: the role of iron, vitamin B12, and folic acid deficiency, and erythropoietin responsiveness.

Thirty six patients with rheumatoid arthritis (RA) (25 with anaemia) were studied to establish the role of iron, vitamin B12, and folic acid deficiency, erythropoietin responsiveness, and iron absorption in the diagnosis and pathogenesis of anaemia in RA. Iron deficiency, assessed by stainable bone marrow iron content, occurred in 13/25 (52%), vitamin B12 deficiency in 7/24 (29%), and folic acid deficiency in 5/24 (21%) of the anaemic patients. Only 8/25 (32%) had just one type of anaemia. The iron deficiency of anaemia of chronic disease (ACD) was distinguished by ferritin concentration, which was higher in that group. Mean cell volume (MCV) and mean cell haemoglobin (MCH) were lower in both anaemic groups, but most pronounced in iron deficient patients. Folic acid, and especially vitamin B12 deficiency, masked iron deficiency by increasing the MCV and MCH. Iron absorption tended to be highest in iron deficiency and lowest in ACD, suggesting that decreased iron absorption is not a cause of ACD in RA. No specific causes were found for vitamin B12 or folic acid deficiency. Haemoglobin concentration was negatively correlated with erythrocyte sedimentation rate in the group with ACD. Erythropoietin response was lower in ACD than in iron deficient patients. It was concluded that generally more than one type of anaemia is present simultaneously in anaemic patients with RA. The diagnosis of each type may be masked by another. Studies on pathogenesis of the anaemia are difficult as deficiencies generally coexist with ACD. Disease activity and, possibly, erythropoietin responsiveness are major factors in ACD pathogenesis.     

Anaemia in the elderly: An aetiologic profile of a prospective cohort of 95 hospitalised patients

Background and objectivesAnaemia is a significant problem in the elderly, and the cause of anaemia in approximately one third of the general population is unidentified. To date, only a few studies have focused on hospitalised patients.Patients and methodsWe prospectively included anaemic patients (according to OMS criteria) aged 65 years and older who were hospitalised in the internal medicine department. The typical clinical data were collected, and a standardised set of biological tests, including cupraemia was performed.ResultsOf 360 total patients, 191 (53%) patients were anaemic; however, 96 patients were excluded because their data were incomplete. Of the remaining 95 patients that were included, 45 were men (47.4%) and 50 were women (52.6%); the mean patient age was 79.7 years (66–101 years). At least one cause of anaemia was diagnosed in 87 of the 95 (91.6%) patients, and anaemia was multifactorial in 44 of the 95 (46.3%) cases. The five most prominent causes of anaemia were inflammation (62.1%), iron deficiency (30.5%), folic acid deficiency (21%), chronic renal failure (17.9%) and cobalamin deficiency (11.6%). Microcytosis was present in only 27.5% of the patients who had an iron deficiency, and macrocytosis was present in only 7.4% of the patients who had a folic acid and/or cobalamin deficiency. The cause of anaemia could not be identified for 8 of the patients. The cupraemia was normal in all the patients.ConclusionA predefined protocol for older hospitalised patients was ability to identify the aetiology of anaemia in 91.6% of the cases; strikingly, anaemia was frequently caused by more than one factor (43.5%). Diagnostic orientation based on the mean corpuscular volume does not appear to correlate with mean cellular volume profile. Finally, anaemia caused by an unknown aetiology is rare and copper deficiency was not documented in any case.     

A prospective, cross-sectional study of anaemia and peripheral iron status in antiretroviral na?ve, HIV-1 infected children in Cape Town, South Africa

Background  

Anaemia is a common manifestation of paediatric HIV infection. Although there are many causes, anaemia of chronic diseases is the most frequent type. In poor countries iron deficiency is widespread. It is probable that many HIV-infected children in these countries are also iron deficient. This study describes the relationship between paediatric HIV infection and anaemia, and documents the peripheral iron status of antiretroviral naive, HIV-infected children.     

Un estudio descriptivo de la enfermedad inflamatoria intestinal en un centro de atención terciario egipcio

Introduction and aimsInflammatory bowel disease (IBD) is a group of chronic intestinal disorders that trigger prolonged inflammation of the digestive tract. Its incidence and prevalence appear to be increasing in the African population and in Egypt. The present study aims to highlight the pattern and management of IBD in Egyptian patients.Materials and methodsTwo hundred patients with IBD were assessed for ulcerative colitis (UC), through the Mayo score, and for Crohn's disease (CD), with the Crohn's disease activity index (CDAI).ResultsMedian patient age was 35 years, with a predominance of females. UC was more common than CD (88% and 12%, respectively) and severity was moderate, in the majority of cases. Most UC patients had left-sided lesions, whereas ileitis was the most common finding (37.5%) in the CD patients. Proctitis was the least common finding in both diseases and Crohn's fistulizing disease was detected in 4.1% of the patients. Interestingly, peripheral arthropathy was the most common extraintestinal manifestation in the IBD patients (70%) and axial arthropathy was the least common (6%). Severe ocular or mucocutaneous involvement was very rare. Finally, biologic treatment was prescribed to 15.4% of the UC patients and 20.8% of the CD patients.ConclusionsAlthough the clinical presentation of IBD in Egypt is comparable to that reported worldwide, diagnoses were found to be delayed. There were fewer cases of CD than UC, but more mild-to-moderate disease severity. The surveillance of patients with IBD must continue and awareness of the disease in the Egyptian medical community needs to increase. A national registry must be established, multicenter studies need to be conducted, and molecular diagnostics is recommended.     

Change of diagnosis during the first five years after onset of inflammatory bowel disease: Results of a prospective follow-up study (the IBSEN Study)

Objective. An exact diagnosis of inflammatory bowel disease (IBD) and further subclassification may be difficult even after clinical, radiological and histological examinations. A correct subclassification is important for the success of both medical and surgical therapeutic strategies, but there is a dearth of information available on the frequency of changes in diagnosis in population-based studies. The objective of this work was prospectively to re-evaluate the diagnosis in an unselected cohort of IBD patients during the first five years after the initial diagnosis. Material and methods. Patients classified as IBD or possible IBD in the period 1990–94 (the IBSEN cohort) had their diagnosis re-evaluated after 1 and 5 years. Initially, the patients were classified as ulcerative colitis (UC), Crohn's disease (CD), indeterminate colitis (IC) or possible IBD. At the 5-year visit, patients were classified as UC, CD or non-IBD. Results. A total of 843 patients (518 UC, 221 CD, 40 IC and 64 possible IBD) were identified. Clinical information was available for 94% of the patients who survived after 5 years. A change in diagnosis was found in 9% of the patients initially classified as UC or CD. A change to non-IBD was more frequent than a change between UC and CD. A large proportion of patients initially classified as IC or possible IBD were diagnosed as non-IBD after 5 years (22.5% versus 50%). When IBD was confirmed in these groups, UC was more frequent than CD. Two changes in diagnosis during follow-up were observed in 2.8% of the patients; this was more frequent in patients initially classified as IC or possible IBD. Conclusions. There are obvious diagnostic problems in a minority of patients with IBD; a systematic follow-up is therefore important in these patients.     

Incidence and clinical presentation of IBD in children: Comparison between prospective and retrospective data in a selected Norwegian population

Objective. The results of recent research suggest that there is an increasing incidence of inflammatory bowel disease (IBD) among children. Newly diagnosed IBD was compared between two consecutive 6-year periods in the same catchment area of southeastern Norway. Material and methods. Children subjected to endoscopy from 1993 to 2004 were recorded retrospectively in the first 6-year period and prospectively for the subsequent period. The mean size of the child population under 16 years in the area was 70,500. The study reports on incidence numbers, age at diagnosis, disease distribution and clinical presentation at diagnosis. Results. There were 23 incident cases of IBD in the first period and 25 in the subsequent period. The rates of Crohn's disease (CD) for the two periods were, respectively, 1.95 and 3.64, and for ulcerative colitis (UC) 3.67 and 2.05/100,000 children/year. Total incidence rates of IBD for the two periods were 5.6 and 5.7, respectively, similar to the findings of the IBSEN study of 1990–94. The change in CD and UC rates from the first to the second period can be explained by better methods of diagnosis. Conclusions. The total incidence of IBD was not changed between time periods, whereas a trend towards an increase in CD and a reduction in UC was recorded. The incidence rates are in accordance with previously reported national and international data from the past decade. The extent of disease in CD and UC may indicate a serious prognosis of IBD among children.     

Articular manifestations in inflammatory bowel disease patients: A prospective study

Background and aimsRheumatic manifestations are frequent in inflammatory bowel disease (IBD) and are associated with a wide range of clinical patterns.MethodsArticular symptoms and signs were investigated by questionnaire in a cohort of 651 pts, mean age 42 ± 14 years, followed at two referral hospitals over a 12-month period.Results142 ulcerative colitis (UC) and 120 Crohn's disease (CD) patients referred articular pain during their IBD history: in 46% this was associated with active IBD, in 56% symptoms were intermittent and in 19% symptoms preceded IBD diagnosis. 62 pts (28 UC, 34 CD) complaining of articular symptoms at the time of the interview, were investigated by the rheumatologist: arthropathy was axial in 52%, oligoarticular in 16% and polyarticular in 23%. Oligoarthritis commonly involved the lower limbs and was more commonly associated with UC. The mean number of small joints involved was significantly higher in CD than in UC pts (9.9 ± 8.2 vs. 5.6 ± 4.3; p < 0.01). Bone scintigraphy was abnormal in 70% of pts.ConclusionsPrevalence of self-reported articular symptoms in IBD patients exceeds 40% with 9.5% incidence during 1-year follow up. Symptoms predict entheropatic involvement of the locomotor system.     

Diagnostic yield of upper endoscopy in paediatric patients with Crohn's disease and ulcerative colitis. Subanalysis of the HUPIR registry

Background, aimsAccording to Porto Criteria upper gastrointestinal (UGI) endoscopy is recommended in patients with suspected inflammatory bowel disease (IBD). Nevertheless, previous studies revealed frequent involvement of UGI tract even in patients with ulcerative colitis (UC). The aim of the present study was to determine the diagnostic role of esophagogastroduodenoscopy (EGD) and assess the prevalence and different aspects of UGI involvement in children registered in the Hungarian Pediatric IBD Registry (HUPIR) from 1st of January 2007 to 31th of December 2009.MethodsTwenty seven institutes provided prospective follow-up data about newly diagnosed IBD patients to HUPIR. The registry was based on detailed questionnaire (76 parameters) involving anamnestic data, laboratory findings, activity indexes, diagnostic procedures, endoscopic examinations (EGD and ileocolonoscopy), and histological data. Localization and phenotype of disease were based on the Montreal classification criteria.ResultsDuring the 3-year period 420 children were diagnosed with IBD, 265 (63%) of them had Crohn's disease (CD), 130 (31%) UC, and 25 (6%) IBD-unclassified (IBD-U). The mean age at diagnosis was 13.2 years (range: 1.2–18 years). EGD was performed in 237 patients (56%), in most cases in patients suffering from CD. Macroscopic lesions on EGD were noted in 64% of patients with CD and 40% of children with UC. Characteristic lesions for CD (ulcer, erosion, aphthous lesion, and granuloma) were noted in 31% of CD patients, however, EGD helped to establish the final diagnosis in 9% of CD patients (diagnostic yield, 9%).ConclusionsThere was a high frequency of UGI involvement in children with CD and UC. One third of CD patients showed significant lesions at upper endoscopy and one patient out of ten had real diagnostic help from EGD.     

Unexplained iron deficiency anaemia: Is it worthwhile to perform capsule endoscopy?

BackgroundIn around 30% of iron deficiency anaemia (IDA) cases a definite diagnosis cannot be made.AimTo investigate the role of capsule endoscopy (CE) in detecting lesions in patients with unexplained IDA after a negative endoscopic, serologic and haematologic diagnostic work up and its possible role in influencing clinical outcome.Methods138 patients suffering from IDA were identified among 650 consecutive patients undergoing CE at our unit.ResultsCE revealed the following positive findings in 91/138 patients: angiodysplasias in 51 patients; jejunal and/or ileal micro-ulcerations in 12; tumours/polyps in 9; erosive gastritis in 4; Crohn's disease in 5; jejunal villous atrophy in 5; a solitary ileal ulcer in 1 and active bleeding in the last 4 patients. Follow up data were available for 80/91 patients (87.9%). In 15 out of 46 patients with angiodysplasias IDA spontaneously resolved without any treatment; 9 patients required iron supplementation; 10 patients healed after lanreotide administration; APC was performed in 9 out of 46 patients and 3 patients underwent regular blood transfusion without any success on IDA. 10 out of the 12 patients with small bowel micro-ulcers spontaneously recovered from IDA whilst 2 patients after iron supplementation. All 9 patients affected by tumours/polyps were surgically addressed. In all erosive gastritis cases, patients recovered from IDA after PPI and Helicobacter pylori eradication. Four patients with Crohn's disease diagnosis restored to health with medical therapy. One out of the 4 patients with jejunal villous atrophy and the sole patient with a solitary ileal ulcer spontaneously healed. In 1 out of 3 patients with active bleeding IDA resolved without further treatment after blood transfusion whilst 2 patients were referred for surgical treatment. At follow up, complete resolution of IDA was achieved in 96.25%.ConclusionsSmall bowel investigation is a matter of great importance in IDA patients after negative upper and lower gastrointestinal endoscopy.     

Inflammatory bowel disease in a colorectal cancer screening population: Diagnosis and follow-up

BackgroundInflammatory bowel disease (IBD) is usually diagnosed in subjects with gastrointestinal symptoms, but may also be asymptomatic and diagnosed incidentally.Aimsto determine the prevalence of IBD in asymptomatic adults.Methodswe identified subjects who underwent colonoscopy between 1 September 2013 and 31 August 2019 in a regional colorectal cancer screening program with endoscopic findings suggestive of IBD, and retrieved their clinical, histological and therapeutic information.Results5116 subjects underwent colonoscopy, and 4640 persons were considered assessable. Of these, 54 (1.16%) had endoscopic findings suggestive of IBD, including 40 of Crohn's disease (CD) and 14 of ulcerative colitis (UC). A definite diagnosis of IBD was made in 19 patients, for an overall IBD prevalence of 0.41%, with 13 cases of CD (0.28%) and 6 of UC (0.13%). The mean follow-up was 26.8 months after the first colonoscopy. Therapy was started in 5 of 13 CD patients and all UC patients.ConclusionEndoscopic findings suggestive of IBD are not infrequent in an asymptomatic colorectal cancer screening population. Visualization of the terminal ileum is recommended in this setting. A definite diagnosis of IBD was made in about 1 out of 3 subjects with endoscopic lesions. Most IBD patients had a mild form of disease, but some needed biologic therapy.     

Iron status of pregnant women at first antenatal booking in Mbarara University Teaching Hospital

An assessment of iron status was made on 96 pregnant women and 29 non-pregnant, non-lactating menstruating women of comparable age group as controls. Anaemia (haemoglobin < 110 g/l) was present in 84.4% of the pregnant women and in 48.3% of the control group. Iron deficiency (serum ferritin < 12.0 micrograms/l) was present in 51.1% of the pregnant group and 37.9% of the control group. Prevalence of anaemia with iron deficiency was 54.7% in anaemic pregnant women. Serum ferritin correlated significantly with low haemoglobin (P < 0.05). Median serum ferritin declined progressively until 31 weeks of gestation. Preliminary studies on their dietetics showed that low animal protein consumption and poor dietary iron bioavailability were associated with anaemia.     

Early microscopic findings in preclinical inflammatory bowel disease

BackgroundThe immune response involved in the pathogenesis of Inflammatory Bowel Disease (IBD) may be present years before the diagnosis, but the characteristics of the disease during the preclinical period have been scarcely investigated.AimTo describe the microscopic findings of preclinical IBD and its relationship with the natural history of the disease.MethodsMedical records from all patients with an incidental diagnosis of IBD during a screening colonoscopy were included in this multicentric and retrospective study. We assessed 15 histologic items in the biopsy samples at diagnosis, and the Geboes score was calculated in patients with Ulcerative Colitis (UC). The main outcome was the development of gastrointestinal symptoms during follow-up.ResultsWe included 110 patients (79 UC, 24 Crohn's Disease (CD) and 7 with unclassified disease). In UC the most common histologic findings were acute or chronic inflammatory infiltrate and crypt epithelial polymorphs, while in CD we observed acute or chronic neutrophilic infiltrate and epithelial irregularity. Granuloma were only observed in 4% of CD patients. Crypt distortion and the infiltration of neutrophils in the epithelium were associated with a higher risk of developing symptomatic disease.ConclusionsPreclinical IBD shows specific microscopic findings and they are associated with the progression to symptomatic disease.
