Autoimmune haemolytic anaemia responding to anti-tuberculous treatment

We describe a very uncommon case of gastric duplication with heterotopic pancreas suggested by an acute pancreatitis and complicated by pseudocyst formation. Diagnostics, hypothesis and management are discussed.     

Warm IgM anti-IT causing autoimmune haemolytic anaemia

A patient with autoimmune haemolytic anaemia due to an autoagglutinin of anti-IT specificity is reported. The antibody was of the IgM class and bound complement; unexpectedly, it reacted optimally at 37 degrees C. A prozone was noted when testing serial dilutions of the patient's serum against appropriate red cells in saline, but was not found when testing an eluate prepared from the patient's red cells. Investigations suggested that the prozone was due to a blocking antibody of high molecular weight, which appeared to be specific for I and IT.     

Appendiceal inflammation in ulcerative colitis

The epoxyalkanoyl derivatives were designed and synthesized as ACE inhibitors. Coupling of unsaturated carboxylic acids with amino acids and following epoxidation with dimethyldioxirane gave the epoxyalkanoyls with high yield. The inhibitory activity of synthesized compounds on angiotensin converting enzyme was IC50 values of 0.06-5.5 microM.     

Risk factors in ulcerative colitis

In 504 Jewish patients with ulcerative colitis the following risk factors were evaluated: sex, age at onset of disease, community group, extent of disease, and duration of disease. The disease was more severe in females. Severe attacks, weight loss, iron deficiency, liver disease and arthritis were significantly more frequent in females than in mles. Mortality was higher in patients who contracted the disease above age 50. The disease appeared to be more severe in patiets of Ashkenazi origin as compared to Orientals. The difference failed to reach statistical signifcance except for mortality. We confirmed the well-known adverse effect of extensive colonic involvement. Severe attacks, a severe course of the disease and extensive colonic involvement are more frequent with increasing duration of the disease.     

X-ray symptoms in ulcerative colitis

Barium enema studies in 200 patients with ulcerative colitis were analyzed according to radiological symptoms. The results of the radiological examination were compared with those of rectoscopy and biopsy. In about 75 per cent of patients good agreement was achieved.     

Nephrotic syndrome in ulcerative colitis

Complicating disorders in various organs outside the intestinal tract are common in ulcerative colitis. This report deals with the occurrence of nephrotic syndrome in two patients with long-standing ulcerative colitis. In the patient studied in most detail, 2 episodes have taken place, the first developing into uremia. After colectomy had been performed, rapid improvement of renal function took place. The morphological changes in kidney biopsies were compatible with the presence of focal glomerular sclerosis. Activity in the complement system and a favorable response to steroid treatment indicate that humoral immune mechanisms are of pathogenetic importance with regard to the renal disease in these two patients. To our knowledge nephrotic syndrome has not previously been described as a complication to ulcerative colitis.     

Rifampicin for ulcerative colitis

The public health approach to injury control is now widely accepted. Since the development of this approach, there has been a shift in the perspective of public health programs to include broader definitions of health. There have also been increasing efforts to evaluate public health interventions in terms of health outcomes at the population level. In this context, it might be appropriate to broaden the focus of injury prevention to target more specifically injuries that are not life-threatening. Although they are not responsible for major morbidity at an individual level, they probably account for the greatest decrement in the health of the population as a whole.     

p-ANCA target antigens in ulcerative colitis

Isolated hearts from two strains of rats bred for sensitivity or resistance to amygdala kindling that also exhibit, in vivo, differential sensitivity to the cardiotoxicity of cocaine were studied. The goal was to determine if the differential cardiotoxic sensitivity was due, at least in part, to intrinsic strain-dependent differences in the heart. The Langendorff preparation was used (n=8 per strain). Hearts were perfused with increasing concentrations of cocaine (5 x 10(-6), 1 x 10(-5), 5 x 10(-5), 1 x 10(-4), and 5 x 10(-4) M) for 5 min with a 5 min washout between exposure to successive concentrations. Consistent with in vivo observations, hearts from genetically slow amygdala kindling rats (Slow) required lower cocaine doses to develop cardiac arrhythmias and arrest as compared to the hearts from genetically fast amygdala kindling rats (Fast). At 5 x 10(-5) M cocaine arrhythmias occurred in 38% (3/8) Slow and 0% Fast hearts. Five of 8 Slow hearts and none of 8 Fast hearts were arrested by 10(-4) M cocaine. Arrest in Fast hearts occurred only with 5 x 10(-4) M cocaine. Cocaine constricted coronary arteries (no significant difference between strains). On the other hand, coronary arteries of Slow but not Fast hearts dilated during cocaine washout after perfusion with all but the highest concentration of cocaine. We conclude that factors intrinsic to the heart and coronary artery influence the sensitivity or response of these structures to cocaine.
