RESUMO

The incidence of cytomegalovirus (CMV) reactivations in patients with multiple myeloma (MM) receiving autologous stem cell transplantation (ASCT) is relatively low. However, the recent increased use of novel agents, such as bortezomib and/or immunomodulators, before transplant, has led to an increasing incidence of Herpesviridae family virus infections. The aim of the study was to establish the incidence of post-engraftment symptomatic CMV reactivations in MM patients receiving ASCT, and to compare this incidence with that of patients treated with novel agents or with conventional chemotherapy before transplant. The study was a survey of 80 consecutive patients who underwent ASCT after treatment with novel agents (Group A). These patients were compared with a cohort of 89 patients treated with VAD regimen (vincristine, doxorubicin, and dexamethasone) before ASCT (Group B). Overall, 7 patients (4.1%) received an antiviral treatment for a symptomatic CMV reactivation and 1 died. The incidence of CMV reactivations was significantly higher in Group A than in Group B (7.5% vs. 1.1%; P = 0.048). When compared with Group B, the CMV reactivations observed in Group A were significantly more frequent in patients who received bortezomib, whether or not associated with immunomodulators (9.4% vs. 1.1%; P = 0.019), but not in those treated with immunomodulators only (3.7% vs. 1.1%; P = 0.396). These results suggest that MM patients treated with bortezomib-based regimens are at higher risk of developing a symptomatic CMV reactivation after ASCT.

RESUMO

AIM: In the elderly, prevalence of bleeding- and/or iron malabsorption-related gastrointestinal (GI) causes of iron deficiency anemia (IDA) has not been addressed yet. The aim of this study was to assess the occurrence of malabsorptive diseases and bleeding lesions of the upper and lower GI tract in early (65-74 year-old) and late (over 75 year-old) elderly group compared with adult (50-64 year-old) outpatients. METHODS: The study enrolled 136 consecutive adult (N.=31), early (N.=48) and late elderly (N.=57) IDA outpatients who were referred to the Gastroenterology Department for IDA evaluation and underwent gastroscopy/histology and colonoscopy. RESULTS: Bleeding lesions were significantly less frequent in adult patients than in elderly patients (29% vs. 49.5%, P=0.0252). The most common bleeding lesions were large hiatal hernia (14.7%) and colon cancer (12.5%). Iron malabsorption diseases (Hp-related pangastritis, atrophic body gastritis and celiac disease) were more frequent in the adult group than in the early elderly group (80.6% vs. 56.2%, P=0.0367). In elderly patients, the observed prevalence of bleeding and iron malabsorption IDA causes was similar, whereas in adult patients iron malabsoptive diseases were more frequently detected (P<0.0001). The occurrence of concomitant IDA causes was not different among the three age-groups. CONCLUSION: In the early and late elderly, almost half of GI IDA causes are related to bleeding lesions which are more frequently observed respect to the adult patients. Iron malabsorption diseases affect almost 60% of early and late elderly groups. As for adult patients, an accurate upper and lower endoscopical/histological evaluation diagnoses IDA causes in the vast majority of the elderly outpatients.

RESUMO

BACKGROUND: Iron-deficiency anaemia (IDA) is common in premenopausal women and menorrhagia is often considered responsible. Aim To evaluate prospectively the occurrence of bleeding and iron malabsorption related gastrointestinal (GI) diseases likely responsible of IDA in premenopausal women regardless of their menstrual flow. METHODS: One hundred and eighty-seven premenopausal women [median age 39 (20-56) years] irrespective of their menstrual flow underwent gastroscopy with gastric and duodenal biopsies and faecal occult blood test (FOBT). Patients over 50 years, positive 1st degree family history for colonic cancer and/or positive FOBT underwent colonoscopy too. RESULTS: Menorrhagia was present in 67.4% of premenopausal women. A possible GI cause of IDA was found in 129/187 patients; in 65.2% the cause of IDA was possibly related to iron malabsorption diseases. GI bleeding as a cause of IDA was found in seven patients. An exclusive GI cause of IDA was found in 26.7% of premenopausal women, whereas a possible GI cause was observed in 34.2% of menorrhagic premenopausal women. The main risk factor for the presence of likely GI causes was the presence of upper GI symptoms (OR 5.2: 95% CI = 1.6-16.4). CONCLUSIONS: Most premenopausal women had a possible upper GI cause of IDA because of diseases related to iron malabsorption. Menorrhagia and a GI cause coexist in one-third of women with iron-deficiency anaemia.

RESUMO

BACKGROUND: Most adults with coeliac disease have a subclinical form of the disease and iron-deficiency anaemia may be the sole presenting symptom. AIM: To evaluate demographic, clinical and biochemical characteristics of adult coeliac disease patients presenting with iron-deficiency anaemia. PATIENTS: A total of 108 iron-deficiency anaemia patients in whom coeliac disease has been diagnosed were studied. As a control group 108 non-coeliac iron-deficiency anaemia patients, comparable for sex and age, were studied. RESULTS: Of the 108 coeliac disease patients, 95 (88%) were female (mean age 34 years, range 19-72) and 13 (12%) were male (mean age 33 years, range 15-65). The median duration of iron-deficiency anaemia before diagnosis was 66 months in coeliac disease patients and 14 months in the iron-deficiency anaemia control group (P = 0.0001). The occurrence of at least one gastrointestinal symptom, not spontaneously reported, was observed in 92 (85%) patients with coeliac disease and in 67 (62%) patients in the control group (P = 0.001). The concomitant presence of diarrhoea, abdominal pain and abdominal bloating was detected in 14% patients with coeliac disease with respect to 3% in the control group (P = 0.005). CONCLUSIONS: The vast majority of coeliac disease patients with iron-deficiency anaemia presentation were unaware of the gastrointestinal symptoms and this relationship is useful for diet compliance.

RESUMO

This study evaluated the impact of a new epoetin alfa dosing regimen on quality of life (QOL), transfusion requirements, and hemoglobin (Hb) levels in 133 patients with low-risk myelodysplastic syndrome (MDS) and Hb < or =10 g/dl. Epoetin alfa 40,000 IU was given subcutaneously twice weekly; after 4 weeks, the dose could be reduced to 40,000 IU weekly in patients achieving erythroid response. QOL was assessed using the functional assessment of cancer therapy-anemia (FACT-An) questionnaire. FACT-An scores increased on average by 7.5 after 4 weeks and by 8.8 after 8 weeks compared with baseline. FACT-An scores were positively associated with Hb values (r=0.53, P<0.01). The mean FACT-An score increase at week 8 was 10.2 in responders and 5.6 in nonresponders. The overall erythroid response rate at week 8 was 68%: 74% in transfusion-independent patients and 59% in transfusion-dependent patients. Of all responders at week 8, response was maintained in 86% at week 12, 71% at week 16, 65% at week 20, and 54% at week 24. Treatment was generally well tolerated. Our data provide new and encouraging results regarding the benefits of 40,000 IU biweekly induction doses followed by 40,000 IU weekly in improving QOL, correcting anemia, and reducing transfusion requirements in low-risk MDS patients.

RESUMO

BACKGROUND: In premenopausal women, iron-deficiency anaemia is common and menstrual flow is often held responsible, but it is not clear whether these women should be submitted to gastrointestinal (GI) evaluation. We aim to prospectively investigate whether premenopausal women with iron-deficiency anaemia benefit from GI evaluation regardless of menstrual flow. METHODS: The study population comprised 59 consecutive premenopausal women with iron-deficiency anaemia. Excluded were women with obvious or suspected causes of anaemia and those < or = 21 years. Heavy menstrual loss was not considered an exclusion criterion. All subjects had: complete blood count, ferritin, non-invasive testing by faecal occult blood (FOB), 13C-urea breath test (13C-UBT), anti-tissue transglutaminase antibodies (tTG) and gastrin levels. Gastroscopy with antral (n = 3), corporal (n = 3) and duodenal (n = 2) biopsies was performed in women with positive 13C-UBT or tTG titre or hypergastrinaemia. RESULTS: Heavy menstrual loss was present in 50.8%. Non-invasive tests were positive in 40/59 (67.8%): 30 had positive 13C-UBT, 12 had hypergastrinaemia, 7 had positive tTG and 3 had positive FOB. Women tested positive were similar to those tested negative as far as concerned age, haemoglobin and ferritin levels and heavy menstrual flow (55% versus 42.1%). All 40 women tested positive underwent gastroscopy with biopsies. Four (10%) had bleeding-associated lesions and 34 (85%) had non-bleeding-associated lesions. As regards upper GI findings, no differences were observed between women with normal and those with heavy menstrual flow. No lower GI tract lesions were detected in the three women with positive FOB. CONCLUSIONS: Our data suggest that premenopausal women with iron-deficiency anaemia benefit from endoscopic evaluation of the upper GI tract irrespective of menstrual flow.

RESUMO

BACKGROUND: The standard evaluation of a patient with iron deficiency anemia includes a complete evaluation of the gastrointestinal tract to identify a source of bleeding. However, even after a careful examination, many patients remain without a diagnosis. Because iron deficiency anemia results from iron loss or defective absorption, we sought to determine the prevalence of potential gastrointestinal sources for iron deficiency anemia in patients without gastrointestinal symptoms. METHODS: Over a 10-month period, 668 outpatients were referred to the University Hematology Department with iron deficiency anemia, defined by a hemoglobin concentration less than 14 g/dL (less than 12 g/dL in women), mean corpuscular volume less than 80 fL, and ferritin level less than 30 microg/L. After excluding patients with obvious causes of blood loss, inadequate diet, chronic diseases, or malignancies, there were 81 eligible patients, 10 of whom refused investigation. The remaining 71 patients (51 women, median age 59 years) underwent colonoscopy, as well as gastroscopy with gastric (antrum and body) and duodenal biopsies. RESULTS: A likely cause of iron deficiency anemia was detected in 60 patients (85%). Diseases associated with bleeding were found in 26 patients (37%), including colon cancer (10 patients), gastric cancer (2), peptic ulcer (7), hiatal hernia with linear erosions (5), colonic vascular ectasia (3), colonic polyps (2), and Crohn's disease (1). Causes not associated with bleeding were found in 36 patients (51%), including 19 with atrophic gastritis, 4 with celiac disease, and 13 with Helicobacter pylori gastritis. Six (8%) patients had coincident gastrointestinal findings, and 11 (15%) had no cause identified. Patients with an identified nonbleeding-associated cause were younger than those with a bleeding-associated cause (median, 56 vs 70 years; P = 0.001) and included 59% of women (n = 30) versus 30% of men (n = 6) (P = 0.04). Hemoglobin level was not related to the site and severity of disease. CONCLUSION: Gastrointestinal diseases that do not usually cause bleeding are frequently associated with iron deficiency anemia in patients without gastrointestinal symptom or other potential causes of gastrointestinal bleeding.

RESUMO

OBJECTIVE: Iron deficiency anemia has been reported as the most frequent extraintestinal symptom in adult celiac disease. Prospective studies on the effect of gluten-free diet on recovery from iron deficiency anemia are lacking. The aim of this study was to verify in adult patients with celiac disease the efficacy of and the time course of recovery from iron deficiency anemia by a gluten-free diet alone. METHODS: We studied 190 consecutive adult patients with iron deficiency anemia, screened for celiac disease by duodenal biopsies. New diagnosed celiac patients were invited to follow a gluten-free diet alone without iron supplementation. After 6 months of diet, duodenal biopsies were performed and hematological tests were repeated at 6, 12, and 24 months. RESULTS: Celiac disease was diagnosed in 26 (24 women, 2 men; 13.7%) adult patients. After 6 months of gluten-free diet 14 of 18 (77.8%) female patients recovered from anemia, but only 5 of 18 (27.8%) reversed from iron deficiency. At 12-month control all but one patient (94.4%) recovered from anemia and 9 patients (50%) from iron deficiency. After 24 months of diet, only the patient who did not recover from anemia at 12-month control was still anemic, whereas 10 patients (55.5%) reversed from iron deficiency. A significant inverse correlation (r = -0.7141, p = 0.0003) between increase of Hb concentrations and decrease of individual histological scores of duodenitis was observed. CONCLUSIONS: A screening for celiac disease should be carried out in adult patients with iron deficiency anemia. Recovery from anemia occurs between 6 and 12 months on a gluten-free diet alone as a consequence of normalization of histological alterations of the intestinal mucosa.

RESUMO

Granulocytic sarcoma (GS) is a rare extramedullary tumor composed of immature myeloid cells. It is usually associated with leukemia or other myeloproliferative disorders, but can also occur without overt hematologic disease, i.e. in patients with a normal bone marrow and no history of acute myelogenous leukemia. This primary extramedullary lesion may indeed represent a diagnostic and therapeutic dilemma for both the hematopathologist and oncologist. We describe a case of GS diagnosed in a nonleukemic patient and review the literature regarding the pathologic features and treatment of this condition.

RESUMO

BACKGROUND: Iron deficiency anemia is the most common form of anemia worldwide. Recent studies have suggested an association between Helicobacter pylori infection and iron deficiency. OBJECTIVE: To investigate the effects of eradicating H. pylori with combination antibiotic therapy on iron deficiency anemia in patients with H. pylori-associated gastritis. DESIGN: Case series. SETTING: University hospital. PATIENTS: 30 patients with a long history of iron deficiency anemia in whom H. pylori-associated gastritis was the only pathologic gastrointestinal finding detected. INTERVENTION: Eradication therapy with two antibiotics and discontinuation of iron replacement therapy. MEASUREMENTS: Complete blood count, ferritin levels, and gastroscopy with biopsy to evaluate H. pylori status. RESULTS: At 6 months, 75% of patients had recovered from anemia (P<0.001), ferritin values increased from 5.7+/-0.7 microg/L to 24.5+/-5.2 microg/L (95% CI, 8.85 to 29.97). After 12 months, 91.7% of patients had recovered from anemia. CONCLUSIONS: Cure of H. pylori infection is associated with reversal of iron dependence and recovery from iron deficiency anemia.

RESUMO

The relationships between acute myeloid leukaemia (AML), acute lymphocytic leukaemia (ALL), chronic myeloid leukaemia (CML) and refractory anaemia with excess of blasts (RAEB) and human herpes virus (HHV)-6 antibody level were investigated in a multicentre case-control study. An association between increased HHV-6 seropositivity and geometric mean titre ratio with AML was shown: P for trend = 0.022, adjusted odds ratio 1.20, 95% confidence interval 1.07-1.33 respectively. No association was found between HHV-6 and ALL, CML or RAEB.

RESUMO

BACKGROUND: The treatment of lymphoproliferative diseases requires extensive histological, immunohistochemical, and cytogenetic diagnosis. The aim of this study was to analyze the results of 66 laparoscopic procedures in the diagnosis, staging, and restaging of hematological malignancies localized in the abdominal cavity. METHODS: Between July 1993 and March 1998, 64 consecutive patients (28 male and 36 female; mean age 46.6 years, range 7 to 69) with diagnosed or suspected lymphoproliferative diseases were referred for primary diagnosis or reassessment and for staging/restaging. RESULTS: Sixty-two out of 66 procedures (93.9%) were completed laparoscopically. CONCLUSIONS: The minimally invasive approach, in the management of lymphoproliferative diseases, is able not only to provide an adequate specimen for proper diagnostic techniques, but also, when compared with open surgery, to offer a large number of advantages.

RESUMO

OBJECTIVE: Atrophic body gastritis (ABG) is characterized by atrophy of the gastric body mucosa, hypergastrinemia, and hypo/achlorhydria. Its association with pernicious anemia is well recognized. Gastric hypo/achlorhydria is known to affect iron absorption but ABG is rarely considered as a possible cause of iron deficiency (microcytic) anemia. The aims of this study were to validate a screening methodology for the detection of ABG in a consecutive series of patients with microcytic and macrocytic anemia and to investigate the clinical and gastric morphofunctional characteristics of the two hematological presentations of ABG. METHODS: A two-part prospective study was carried out. Part A aimed to validate the screening methodology to detect the presence of ABG in patients with macrocytic and microcytic anemia who have no specific GI symptoms, by measuring their gastrin levels and verified by performing gastroscopy with biopsy. Part B aimed to detect the presence of ABG in a larger sample of anemic patients by our validated method and, by pooling the data of ABG patients, to determine the clinical, gastric histological, and functional characteristics pertaining to the macrocytic and microcytic presentations of ABG. RESULTS: In part A, ABG was detected in 37.5% of patients with macrocytic and in 19.5% of those with microcytic anemia. Pooling the data of the ABG patients from part A and part B, microcytic ABG patients were on average 20 yr younger than those with macrocytic anemia. The majority of microcytic ABG patients were female, most of whom were premenopausal. H. pylori infection was widely represented in the microcytic ABG group (61.1%). They also had a lesser grade of body mucosal atrophy and lower hypergastrinemia levels, suggesting a less severe oxyntic damage of shorter duration. CONCLUSIONS: Macrocytic anemia is not the only hematological presentation of ABG. Physicians evaluating patients with unexplained iron deficiency anemia should consider ABG as a possible cause by determining fasting gastrin levels and performing gastroscopy with biopsies of the body mucosa.

RESUMO

During a 7-month period a prospective study of 71 anaemic patients (29 males and 42 females) over the age of 50 was undertaken in order to identify patients with myelodysplastic syndrome (MDS). The mean values of mean corpuscular volume (MCV), serum ferritin, folate, vitamin B12 and red cell folate (RCF) of patients grouped according to the diagnosis were compared to those observed in age-matched blood donors. Forty-four of the 71 elderly patients showed macrocytic anaemia: 21 of them had gastric disease and the remaining 23 MDS. Two further patients with MDS showed microcytic anaemia. The 25 patients diagnosed with MDS were subclassified according to the FAB nomenclature: 9 had a refractory anaemia with excess of blasts and 16 refractory anaemia. The mean values of MCV, serum folate, ferritin, vitamin B12 and RCF were statistically different between patients with macrocytic anaemia due to gastric disease and patients with MDS. Among patients with MDS, the RCF level pathologically high was inversely correlated to the haemoglobin level (r=-0.39; p<0.05). Thus the RCF and serum folate may represent useful parameters for the diagnosis of MDS in elderly anaemic patients.

RESUMO

BACKGROUND: Very little information is presently available regarding risk factors for essential thrombocythemia (ET). METHODS: A case-control study was performed to study the possible association between ET and selected behavioral, occupational, and environmental exposures. RESULTS: Thirty-nine patients aged 20 years or older and 156 controls were enrolled in 2 Italian Hematology Departments located in Rome and Pavia. Controls were recruited among outpatients seen in the same hospitals and matched 4:1 to the patients after stratification by age and sex. Odds ratio (OR) estimates suggest an association between ET and hair dye use (in particular the use of dark hair dye for periods longer than 10 years: OR - 5.3; 95% confidence interval [CI], 1.4-19.9), living in houses built with tuff (a material with a high concentration of gamma-emitting radionuclides and radon) for longer than 9 years (OR = 5.1; 95% CI, 1.2-22.1), and selected occupations (electrical worker and shoemaker, OR +infinity and 2.7; 95% CI, 0.5-16 respectively). CONCLUSION: Behavioral exposures such as hair dyes, living in a tuff house, and working as an electrician are significantly associated with ET development. The data are consistent with those observed in acute leukemias.

RESUMO

BACKGROUND: The estimated incidence of acute promyelocytic leukemia (APL) is approximately 6 cases per 10 million people per year with no apparent differences between sexes. The age of APL cases is younger than that of other acute myeloid leukemias (AML). Spatial and temporal clusters of APL have been reported. These observations suggest a possible selective role for environmental and/or occupational factors in APL development. METHODS: A multicenter case-control study was carried out on risk factors for acute leukemias and preleukemias. In this report data related to APL are selectively analyzed from the larger study to identify specific risk factors. RESULTS: The case-control study on 38 cases of APL showed a strong association with shoemaking (odds ration 6.3, 95% confidence interval 1.3-31.1). A moderate leukemogenic effect from living in houses built with tuff, a polous building material containing gamma-emitting radionuclides and having a high radon concentration, and from using hair dyes was also suggested. CONCLUSIONS: These data, together with the reported spatial and temporal clustering of APL, support the hypothesis of specific environmental and/or occupational risk factors for APL among other AML subtypes and indicate the need for additional ad hoc multicenter studies.

RESUMO

There is a wealth of experiences concerning cancer and leukemia induced in human populations by radiation. The contribution of the nuclear industry to the radiation exposure of the general population is small, but there is the risk of catastrophic accidents causing a large number of deaths. The authors describe the case of a 48 year old black man accidentally exposed to the effects of radiations during the nuclear disaster of Chernobyl in 1986. The patient showed, many years later, a predominantly cutaneous high-grade T cell lymphoma, which was refractory to traditional treatments but sensitive to high doses of a recombinant interferon. Unluckily the patient died, six months later, because of autoinfection overwhelming. The goal of the authors is again to ask to reflect on the risk of the use of nuclear power and to debate the possible choice of the still experimental treatments.
