BACKGROUND: Helicobacter pylori eradication rates have tended to decrease recently possibly related with increasing antibiotic resistance. The present study investigated the efficacy of three different ranitidine bismuth citrate (RBC) based triple regimens in a population with high prevalence of H. pylori. METHODS: 300 consecutive H. pylori positive patients with non-ulcer dyspepsia were randomized into three regimens: (1) RBC 400 mg, amoxicillin 1000 mg and tetracycline 500 mg [RBC-AT], (2) RBC 400 mg, amoxicillin 1000 mg and clarithromycin 500 mg [RBC-AC], (3) RBC 400 mg, metronidazole 500 mg and tetracycline 500 mg [RBC-MT]. Tetracycline was given q.i.d, all other drugs were given b.i.d. for 14 days. Gastroscopy and (14)C-Urea breath test (UBT) were performed before enrollment and UBT only was repeated 6 weeks after the end of treatment. RESULTS: 274 patients completed the protocols. The overall 'intention to treat' and 'per protocol' H. pylori eradication rates in all subjects were 57.6% (95% CI: 52-63) and 63.1% (95% CI: 57-68), respectively. The eradication rates achieved in the groups (RBC-AT, RBC-AC and RBC-MT) were 64.4% (95% CI: 54-74), 66.2% (95% CI: 56-76), and 58.9% (95% CI: 49-68) on 'per protocol' analyses, respectively. There was no difference in eradication rates, compliance and major side effects between the groups. CONCLUSION: The current RBC-based H. pylori eradication therapy is not adequately effective. 相似文献

Background: The ventricular late potential (VLP) detected using the technique of signal average electrocardiography (SAECG) interacts with several factors, primarily time. Method: In this study, we examined the interaction, over time, of VLP with the initial ischemic burden and enzyme levels in acute myocardial infarction. Patients diagnosed as having acute myocardial infarction were included in the study. On the first day, the patients underwent enzyme analysis and electrocardiography (ECG) follow‐up every 6 hours. A 24‐hour ambulatory ECG was performed on the seventh day in order to determine the ischemic burden. SAECG findings (TQRS, RMS, LAS were obtained on the seventh day, in the first and third months. The study was continued with the patients who did not require angioplasty as decided with angiographic evaluation in the first month. Results: The study included 30 patients with acute myocardial infarction (mean age 51 ± 12, 28 males and 2 females). The initial mean CK‐MB levels and the mean ischemic burden were 98 ± 31 U/L and 44 ± 96 minutes. The TQRS (ms), LAS (ms), and RMS (μV) values (mean ± SD) obtained at day 7, month 1, and month 3 are 97 ± 12, 96 ± 9, 103 ± 11, P = 0.01; 31 ± 10, 31 ± 11, 32 ± 10, P = 0.46; 43 ± 28, 41 ± 26, 33 ± 25, P = 0.01, respectively. We observed that the TQRS and RMS values changed significantly with time, but these levels of significance disappeared when adjusted for the initial ischemic burden and CK‐MB levels (P = 0.06; P = 0.53). The VLP frequency was 33% at day 7 and 23% at month 3. Unlike the CK‐MB level, the initial ischemic burden was significantly different between the patients with and without VLP at month 3 (150.85 ± 149.28, 12.34 ± 26.48, P = 0.001). When tested together with age and gender, it was found that the high initial ischemic burden increased the possibility of VLP (OR: 24, Cl: 2.09–279.52, P = 0.01) at month 3. Conclusion: SAECG findings in patients with myocardial infarction changed with time; however, this change occurred depending on the initial ischemic burden and CK‐MB levels. Of these, only the initial ischemic burden, especially in high levels, was a determinant for the presence of VLP in the late period of myocardial infarction. A.N.E. 2002;7(3):242–246 相似文献

Isolated TSH deficiency is a rare cause of congenital hypothyroidism. We here report four children from two consanguineous Turkish families with isolated TSH deficiency. Affected children who were screened at newborn age had an unremarkable TSH result and a low serum TSH level at diagnosis. Age at diagnosis and clinical phenotype were variable. All affected children carried an identical homozygous splice site mutation (IVS2 + 5 G--> A) in the TSHbeta gene. This mutation leads to skipping of exon 2 and a loss of the translational start codon without ability to produce a TSH-like protein. However, using specific monoclonal antibodies, we detected a very low concentration of authentic, heterodimeric TSH in serum, indicating the production of a small amount of correctly spliced TSH mRNA. By genotyping all family members with polymorphic markers at the TSHbeta locus, we show that the mutation arose on a common ancestral haplotype in three unrelated Turkish families indicating a founder mutation in the Turkish population. These results suggest that this TSHbeta mutation is among the more common TSHbeta gene mutations and stress the need for a biochemical and molecular genetic workup in children with symptoms suggestive of congenital hypothyroidism, even when the neonatal TSH screening is normal. 相似文献

The aim of the study is to review the clinical manifestations and the hematological findings of brucellosis and pancytopenia, with or without hematological malignancies. The records of 202 patients with brucellosis were evaluated retrospectively. Among these cases of brucellosis seen in a 6 year period between April 1999 and June 2005, 30 patients with pancytopenia were identified. The most common manifestation was fever, followed by weight loss, anorexia, malaise, arthralgia, and hepatosplenomegaly. Bone marrow biopsies revealed hypercellularity or normocellularity. The most common findings in the bone marrow evaluation were histiocytic hemophagocytosis and granulomas. Among all cases, we diagnosed 5 hematological malignancies (1 acute myelogenous leukemia, 2 acute lymphoblastic leukemia, and 2 multiple myeloma) concurrently with brucellosis. The clinical symptoms and findings were similar in patients with and without malignancies. In cases with malignancies, the bone marrow biopsy revealed predominant primary disease involvement. Significant increases in ESR and CRP, severe anemia and thrombocytopenia were observed in patients with malignancies. Peripheral blood counts in patients without malignancies returned to normal after antibiotic treatment for brucellosis. However, pancytopenia in two patients with malignancies did not recover because of primary resistant disease. We conclude that while histiocytic hemophagocytosis may be considered as a major cause of pancytopenia, leukemic infiltration can also be an extreme and unusual cause of pancytopenia in patients in whom brucellosis was concurrently diagnosed with hematological malignancies. 相似文献

Objectives: To determine whether the cellular inflammatory markers of activated macrophages, neopterin (NEO), chitotriosidase activity and the acute-phase inflammatory marker C-reactive protein (CRP) are elevated in pregnancy with threatened preterm labor (TPL).Methods: Thirty-two pregnant women with TPL and 32 women with uncomplicated pregnancy (UP) were included this study. The primary aim was to compare the NEO, chitotriosidase activity and CRP levels between women with TPL and women with UP.Results: NEO levels were all significantly elevated in patients with TPL compared to UP (median 25–75%; 9.61 [8.47–12.29] versus 4.46 [3.59–6.92], respectively; p?0.001). Chitotriosidase activity was significantly elevated in pregnant women with TPL compared to UP (median 25–75%; 59.00 [38.00–87.25] versus 43.50 [23.25–65.25], respectively; p?=?0.036). However, CRP levels were not different in women with TPL compared to UP (p?=?0.573). Furthermore, a significant moderate negative correlation was found between delivery week and NEO level (r?=??0.557, p?=?0.001). However, a significant correlation was not seen between delivery week and chitotriosidase activity (r?=??0.042, p?=?0.741).Conclusions: Inflammatory markers such as NEO and chitotriosidase activity, which are markers of macrophages, are more elevated in pregnant women with TPL than in women with UP. These data suggest that there are striking increases in inflammation and cellular immune activation in TPL. 相似文献

Pulsed Doppler tissue imaging can help to identify patients with right ventricular infarction 总被引:3,自引:0,他引:3
This study was planned to assess whether tissue Doppler imaging is a useful method for the detection of the right ventricular myocardial infarction. Forty-eight patients with acute inferior myocardial infarction and 24 age- and sex-matched healthy controls were included in this study. Twenty-four patients had electrocardiographic signs of inferior myocardial infarction without right ventricular infarction (group I), and the other 24 patients had electrocardiographic signs of inferior myocardial infarction with right ventricular infarction (group II). From the echocardiographic apical four-chamber view, peak systolic, early diastolic, and late diastolic velocities of the tricuspid annulus at the right ventricular free wall were recorded with the use of pulsed-wave Doppler tissue imaging. The tricuspid annular peak tissue Doppler imaging systolic velocity was significantly lower in group I (14.03 ± 2.57cm/s, P 0.005) and in group II (8.50 ± 0.84cm/s, P 0.005) than in controls (16.63 ± 2.31cm/s). The tricuspid annular peak systolic (8.50 ± 0.84cm/s vs 16.63 ± 2.31cm/s) and peak early diastolic (10.99 ± 3.28cm/s vs 19.39 ± 4.3cm/s) velocities were significantly lower in group II than in group I, as compared with controls (P 0.001). Peak early diastolic velocity of tricuspid annulus (10.99 ± 3.28cm/s vs 19.39 ± 4.3cm/s) was significantly lower in group I than in controls (P 0.001); however, late diastolic velocity was significantly lower in group II (15.98 ± 5.08cm/s, P 0.05) than in group I (18.21 ± 2.63cm/s, P 0.05) and in controls (19.02 ± 5.29cm/s). The results of this study indicate that tricuspid annular peak systolic and early diastolic velocities are reduced in patients with right ventricular infarction. The velocity of the tricuspid annulus by tissue Doppler imaging is simple and can be used to distinguish whether patients with inferior myocardial infarction have right ventricular infarction.This study was presented at the XXIII.

Alexithymia and anger in patients with fibromyalgia 总被引:2,自引:0,他引:2
Our objective was to delineate the relevance of the personality construct alexithymia and anger-in in patients with fibromyalgia syndrome. Fifty subjects with fibromyalgia syndrome were compared to 20 subjects with rheumatoid arthritis and 42 healthy controls on the measures of anxiety, depression, anger, alexithymia, pain intensity and disability. There was a significant difference on the measures of anxiety and anger between FMS and RA groups, and also between FMS patients and healthy controls. There was a significant difference between FMS patients and healthy controls on the measures of depression, difficulty in identifying feelings subscale of TAS (TAS-dif), and total alexithymia scores. When the severity of pain was controlled for, there was a significant difference on the measures of anger and alexithymia between the FMS and the RA groups. Fibromyalgia patients were more alexithymic than rheumatoid arthritis patients even when the level of depression was controlled for. Anger towards oneself, which is anger-in, was higher in patients with fibromyalgia patients than in the rheumatoid arthritis sample. A stepwise regression model showed that the anger-out scores and the anxiety scores predicted the level of pain severity, and this explained 32% of the variance in the fibromyalgia syndrome group. Although anger-in is consistently higher in fibromyalgia patients, it is the behavioral expression of anger, together with anxiety, that predicts the severity of the pain. The difficulty of identifying feelings, rather than other dimensions of alexithymia, seems to be associated with fibromyalgia.Abbreviations CLBP

Our aim was to investigate the effects of hyaluronan on inflammatory cytokines in the synovial fluid of patients with knee osteoarthritis. The study was single blind, placebo-controlled, and randomized. We administered hyaluronan to 22 patients in the study group and placebo to 19 in the control group. Enzyme-linked immunosorbent assay was used to determine the levels of cytokines. Both HA and placebo caused a significant decrease in interleukin (IL)-6 levels (P=0.0001 and P=0.04, respectively). But it was more significant in the study group. However, IL-8 and tumor necrosis factor alpha (TNF-) levels did not change in either group (P>0.05). The amount of effusion decreased significantly in the study group (P=0.001) but not in the control group (P=0.133). It can be concluded that hyaluronan considerably decreased IL-6 levels, which correlated with clinical improvement, but had no effect on IL-8 and TNF- levels in synovial fluid. However, larger studies with longer follow-up periods are needed to explain the effect of hyaluronan on cytokines. 相似文献
