RESUMO

BACKGROUND/AIMS: In patients with active ulcerative colitis (UC), pharmacologics, although initially effective in most patients, are associated with refractoriness, loss of response or unfavourable side effects as additional morbidity factors. Depletion of myeloid lineage leucocytes like the CD14(+)CD16(+) monocyte phenotype, which is a major source of tumour necrosis factor-α, by granulocyte/monocyte apheresis (GMA) if effective, is also known to be free from side effects. METHODS: In clinical practice setting, 77 consecutive patients with moderate to severe UC, who failed to respond to first-line medications received GMA with the Adacolumn as remission induction therapy. Patients who achieved remission were followed for 3 years. RESULTS: Among the 77 patients, 46.8% were corticosteroids-naïve, 26% corticosteroid-dependent and 27.3% corticosteroid-refractory. The overall clinical remission rate was 79.2%, and the overall mucosal healing (MH) rate according to the Mayo endoscopic subscore ≤1 was 58.5%. MH rates in corticosteroid-naïve, corticosteroid-dependent and corticosteroid-refractory subgroups were 70.8, 56.3, and 38.5%, respectively. The 3-year sustained clinical remission rates in corticosteroid-naïve, corticosteroid-dependent and corticosteroid-refractory subgroups were 83.3, 68.8, and 23.1%, respectively. CONCLUSION: Corticosteroid-naïve patients appeared to benefit the most from the Adacolumn GMA, and attain a favourable long-term clinical course. Accordingly, GMA should be a first-line therapy in this clinical setting.

RESUMO

We examined the relationship between host as well as tumor factors and postoperative survival rate in patients who received combination therapy of mitomycin C + fluoropyrimidine oral antineoplastics + protein-bound polysaccharide K (PSK) (MFP therapy) after curative resection of colorectal cancer. Markers that determine prognosis, such as preoperative humoral factors (complement 3 and 4), immunosuppressive acidic protein (IAP), lymphocyte transformation (cellular factors) induced by phytohemagglutinin (PHA), pokeweed mitogen (PWM), and PSK, and various tumor markers (CEA, CA19-9) were measured. For each parameter, patients were divided into a high-level and a low-level group according to a predetermined cut-off value, and survival rates were compared between the two groups. The host factors that determined prognosis were 1-month postoperative IAP level [IAP(1M)], preoperative PHA value, and preoperative CA19-9 level. The levels of IAP(1M) <740 microg/ml, preoperative PHA > or =210 (SI value), and preoperative CA19-9 <13 U/ml were associated with a favorable prognosis. When combined with the tumor factors, the prognosis was favorable in Dukes A+B cases with preoperative CA19-9 <13 U/ml, and in Dukes C cases with preoperative PHA > or =210 SI. By the Cox proportional hazard model analysis, among IAP, PHA and CA19-9, CA19-9 was the strongest host factor associated with the prognosis of MFP therapy.

RESUMO

BACKGROUND: Cytomegalovirus (CMV) is frequently detected in ulcerative colitis (UC) lesions of steroid-refractory patients. This has led to the suspicion that CMV might cause colitis and steroid refractoriness. METHODS: During 2003 and 2011, 187 consecutive patients were divided into group I (n = 105), corticosteroid-free and thiopurine-free in the past 6 months, and group II (n = 82), all corticosteroid refractory. The combination of serum CMV immunoglobulin (Ig)M, CMV IgG, CMV antigenemia (Ag), and real-time polymerase chain reaction assays were performed to identify CMV(+) patients. RESULTS: In group I, 79 patients were CMV IgG(+) and 26 patients were CMV IgG(-) and CMV IgM(-). In group II, 61 patients were CMV IgG(+), 1 CMV IgM(+), and 20 CMV IgG(-) and CMV IgM(-). All CMV IgG(+) patients were screened for CMV Ag. In group I, 6 of the 79 CMV IgG(+) patients were CMV Ag(+). In group II, 27 patients were CMV Ag(+). Colonoscopy was performed in all patients before screening for CMV. Similar colonoscopic features including punched out ulcers, geographic ulcers, and irregular ulcers were found in both CMV(+) and CMV(-) patients, without any striking difference between the 2 groups. CONCLUSIONS: CMV reactivation might be encouraged by immunosuppressive drugs, like corticosteroids, immunomodulators, and therefore, patients with UC are at a high risk of CMV reactivation, potentially exacerbating UC. However, this study of 187 patients, CMV(+) and CMV(-), could not find colonoscopic features unique to CMV, except that CMV might be one factor for steroid refractoriness, and UC exacerbation.

RESUMO

Autoimmune hepatitis (AIH) is a disorder of unknown etiology, which often progresses to cirrhosis and carries a high mortality, even though its treatment with corticosteroids has become common. Hepatocellular carcinoma (HCC) has been reported as a rare complication of AIH. We describe herein a patient with HCC associated with AIH, in whom microwave coagulation therapy provided a means of definitive management, and we also review the literature. Male sex and longstanding cirrhosis seem to be the risk factors for hepatocarcinogenesis in AIH. The prognosis of this disease is extremely poor because of the low resectability caused by poor hepatic reserve. It is important to pay attention to hepatic disorders and the possible development of HCC at the time of diagnosis of AIH. Surgeons should select suitable treatment, without undue surgical stress, whenever the diagnosis of HCC has been established. Microwave coagulation therapy is a preferred option for the treatment of high-risk patients with poor hepatic reserve or unresectable multiple HCCs.
