OBJECTIVETo compare the incidences of anemia, osteoporosis, and irritable bowel syndrome (IBS) after the application of different endocrine therapies in patients with prostate cancer.

METHODSTotally 125 patients aged 58 to 84 years with biopsy-confirmed local prostate cancer were recruited between September 2008 and September 2010. Of them 52 treated with orchiectomy (castration group) and 73 with luteinizing hormone-releasing hormone analogue (goserelin acetate 3.6mg/month) combined with androgen antagonist (bicalutamide 50mg/d) for at least 12 months (hormone group), but without blood transfusion or erythropoietin. Changes in total testosterone (TT), free testosterone (FT), prostate specific antigen (PSA), hemoglobin (Hb), red blood cell (RBC), hematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red blood cell distribution width (RDW), bone mineral density (BMD) and gastrointestinal symptom rating scales (GSRS) were recorded and analyzed before treatment and 12 months after the initiation of treatment.

RESULTSIn the castration group, after 12 months, TT (P=0.0007), FT (P=0.0003), PSA (P=0.0006), Hb (P=0.0001), RBC (P=0.020), Hct (P=0.016), Z-score of lumbar spine (P=0.008), and femoral neck (P=0.004) decreased significantly, and GSRS (P=0.029) increased significantly. In hormone group, after 12 months, TT (P=0.0008), FT (P=0.0006), PSA (P=0.0006), Hb (P=0.0003), RBC (P=0.0001), Hct (P=0.0002), Z-score of lumbar spine (P=0.002), femoral neck (P=0.0002), and RDW (P=0.045) decreased significantly, and GSRS (P=0.010) increased significantly. After 12 months, TT (P=0.004), FT (P=0.012), PSA (P=0.007), Hb (P=0.016), Z-score of lumbar spine (P=0.033), and femoral neck (P=0.015) in hormone group were significantly lower than in the castration group, while GSRS (P=0.027) in hormone group was significantly higher than in the castration group. The incidences of anemia (P=0.006), osteoporosis (P=0.009), and IBS (P=0.022) were significantly different between these two groups. The serum level of testosterone was positively correlated with Hb, RBC, Hct, and BMD in both groups (P=0.039). Negative linear correlations could be seen between serum level of testosterone and GSRS in both groups (P=0.021), and between serum level of testosterone and RDW in medical group only (P=0.044).

CONCLUSIONThe endocrine therapies, particularly maximal androgen blockage, in patients with prostate cancer can be associated with anemia, osteoporosis, and IBS.

Evaluation of the mechanism of anemia in cancer patients might help to select patients for the more efficient use of erythropoietin (EPO, a growth factor for erythroid precursor cells). For this, we investigated whether the production of EPO responds to anemia and the bone marrow responds to EPO appropriately, and whether chronic inflammation is inhibitory to erythropoiesis in anemic cancer children. Serum levels of EPO, soluble transferrin receptor (sTfR), tumor necrosis factor (TNF)-alpha, and erythrocyte sedimentation rate (ESR) in anemic cancer children were measured by enzyme-linked immunosorbent assay and then the correlation coefficients between those parameters and hemoglobin (Hb) were determined. Both in leukemia and in solid tumor patients, there were significant inverse correlations between Hb and EPO (leukemia: tau=-0.547, p<0.0001; solid tumor: tau=-0.591, p<0.0001), and between sTfR and EPO (leukemia: tau=-0.223, p<0.05; solid tumor: tau=-0.401, p<0.05). In contrast, sTfR showed a correlation with Hb in leukemia (tau=0.216, p<0.05) but not in solid tumor patients. sTfR was suppressed in 53% of anemic episodes of leukemia and 78% of those of solid tumor patients. Our results suggest that in cancer children, the EPO production is not defective and chronic inflammation is not inhibitory to erythropoiesis. Rather, the defective erythropoiesis itself is thought to be responsible for the anemia.

Nephrotic syndrome has been described as one of the clinical forms of chronic graft-versus-host disease (cGVHD), but a limited number of cases have been described. We experienced a young female patient with nephrotic syndrome developed 22 months after allogeneic hematopoietic stem cell transplantation (HSCT) for severe aplastic anemia. She had been well after successful management for gut-limited cGVHD until she developed a clinical nephrotic syndrome with hypoalbuminemia of 2.0 g/dL and 24-hr urine protein of 6.88 g/dL. On physical examination and laboratory findings, there was no other evidence of cGVHD. Clinical and renal biopsy findings were consistent with cGVHD-related membranous nephropathy, and immunosuppressive agents with cyclosporine and prednisone were prescribed. After 3 month of treatment, the proteinuria decreased to normal range; and the patient from nephrotic syndrome nearly recovered. We recommend cGVHD-related glomerulonephritis should be considered in all patients with hypoalbuminemia following allogeneic HSCT, even if there is no other evidence of clinical GVHD.

Renin-angiotensin system (RAS) has been shown to be involved in the growth, production, proliferation and differentiation of the bone marrow (BM) hematopoietic cells, while aplastic anemia (AA) is a disease in which proliferation ability of the BM hematopoietic cells is damaged with defective hematopoietic microenvironment. To investigated the pathogenesis of AA, the rennin activity, angiotensin I (Ang I) and angiotensin II (Ang II) concentration in peripheral blood and BM of 22 AA patients were detected by radioimmunoassay, 16 nonhematological disease patients with normal blood counts and BM picture were used as control, and the difference between two groups was compared. The results showed that BM Ang II concentration in the AA patients was significantly lower than that in the control (P < 0.01). In nonhematological disease patients, Ang II concentration in BM was significantly higher than that in peripheral blood, the renin activities and Ang I concentrations were not significantly different in the two groups (P > 0.05). In conclusion, the decreased BM Ang II concentration in AA patients may be involved to the pathogenesis of AA.

OBJECTIVEAnti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis is a disorder with poor prognosis. This study aimed to improve the diagnosis and treatment of ANCA associated vasculitis of children, to analyze the clinical features, pathological characteristics and the prognosis of children with ANCA-associated vasculitis.

METHODFifteen children with ANCA associated vasculitis who were hospitalized from 2003 to 2012 in our hospital were included. Their data of pre-diagnosis status, clinical manifestations, renal pathology, treatment and prognosis were reviewed retrospectively.

RESULTOf the 15 children, 11 were girls and 4 boys with a mean age of 10.7 years. Fourteen children were categorized as microscopic polyangitis. The time to diagnosis varied from 0.5 month to 40 months. Hematuria and proteinuria were revealed by urine analysis in all of them, only 6 children complained with gross hematuria or edema of oliguria. Decreased glomerular filtration rate was revealed in 13 children, 8 of whom had a creatinine clearance rate of less than 15 ml/(min·1.73 m(2)). Twelve children underwent renal biopsy, crescent formation was found in 11 children. Most of the crescents were cellular fibrous crescents or fibrous crescents. Six children were diagnosed as crescentic nephritis; the process of rapidly progressive nephritis was only observed in 2 children. Segmental glomerulosclerosis or global glomerulosclerosis were found in 10 children, 3 of them were diagnosed as sclerotic glomerulonephritis. Anemia and pulmonary injury were the most common extra renal manifestations. Other extra renal manifestations included rash, pain joint, gastrointestinal symptoms, abnormal findings of cardiac ultrasonography and headache. Eight children were treated with steroid combined with cyclophosphamide, 4 were treated with steroid and mycophenolate mofetil, 2 were treated with steroid, cyclophosphamide and mycophenolate mofetil, 3 children were treated with plasma exchange. Fourteen children were followed up for 0.5 month to 4 years. The renal function did not recover in children with creatinine clearance rate of less than 30 ml/(min·1.73 m(2)), who showed crescentic glomerulonephritis or sclerotic glomerulonephritis. The children who had creatinine clearance rate of more than 30 ml/(min·1.73 m(2))had better prognosis.

CONCLUSIONMore attention should be paid to ANCA-associated vasculitis among school age girls with anemia or pulmonary diseases. The renal damage was serious in children; however, the clinical manifestations were not obvious. Children with a creatinine clearance rate of less than 30 ml/(min·1.73 m(2)) had poor prognosis. Early accurate diagnosis is very important.

OBJECTIVETo explore impaired erythropoiesis and relative inadequacy of erythropoietin production in the anemic cancer patients and the correlation of tumor necrosis factor-alpha (TNF-alpha) or interferon-gamma (IFN-gamma) with inadequate erythropoietin (EPO) response and impaired erythropoiesis in cancer patients with anemia.

METHODSFifty adult anemic and 15 non-anemic tumor patients were studied. Serum EPO levels were measured by radioimmunoassay (RIA) and serum soluble transferrin receptor (sTfR). TNF-alpha and IFN-gamma levels by enzyme-linked immunosorbent assay (ELISA). Log transformed EPO and sTfR values were used in statistical analysis. The R correlation analyses were performed.

RESULTSThe mean serum immunoreactive erythropoietin level in anemic cancer patients [(23.11 +/- 10.00) IU/L] was not significantly higher than in healthy people (P = 0.053), but significantly lower than in IDA patients with similar degree of anemia [(43.00 +/- 22.00) IU/L, P < 0.01]. Both O/P EPO [0.88 (0.54-1.10)] and O/P sTfR [0.89 (0.57-1.22)] were significantly lower in anemic cancer patients than in controls and in non-anemic cancer patients. There was no significant difference between the latter two groups. Furthermore, the expected inverse linear relation between serum EPO and hemoglobin levels was absent in the anemic cancer patients, and so did the relation between serum sTfR and hemoglobin levels. There was no correlation between O/P EPO and O/P sTfR. The serum levels of both TNF-alpha and IFN-gamma in anemic cancer patients [(25.75 +/- 26.71) ng/L, (50.49 +/- 42.12) ng/L, respectively] were significantly higher than those in healthy controls (both P < 0.01) or in nonanemic cancer patients (both 0.01 < P < 0.05), and so did between non-anemic cancer patients and controls. The serum levels of TNF-alpha were inversely correlated with hemoglobin levels (r = - 0.40, P = 0.004), O/P EPO (r = -0.32, P = 0.025) or O/P sTfR (r = -0.36, P = 0.01); while serum levels of IFN-gamma were inversely correlated with hemoglobin levels (r = -0.36, P = 0.01) or O/P sTfR (r = 0.39, P = 0.006), but not with O/P EPO. Conclusions Anemia of cancer is due to impaired erythropoiesis and relative inadequacy of EPO production. TNF-alpha might inhibit EPO production and erythropoiesis, while IFN-gamma maybe directly inhibit erythropoiesis and be independent of EPO response inadequacy.

OBJECTIVETo determin the extent to which parvovirus B19 (B19V) and co-infection of B19V and malaria contribute to risk of anaemia in children.

METHODSB19V DNA and malaria parasites were screened for 234 children at the PML Children's Hospital in Accra. The role of B19V and co-infection with B19V and malaria in anaemia was evaluated by analysing full blood cell counts, malaria and B19V DNA results from these children.

RESULTSThe prevalence of B19V, malaria and co-infection with B19V and malaria was 4.7%, 41.9% and 2.6%, respectively. Malaria posed a greater risk in the development of mild anaemia compared to severe anaemia (OR=5.28 vrs 3.15) whereas B19V posed a higher risk in the development of severe anaemia compared to mild anaemia (OR=4.07 vrs 1.00) from a non-anaemic child. Persons with co-infection with B19V and malaria had 2.23 times the risk (95% CI=0.40-12.54) of developing severe anaemia should they already have a mild anaemia. The degree of anaemia was about three times affected by co-infection (Pillai's trace=0.551, P=0.001) as was affected by malaria alone (Pillai's trace=0.185, P=0.001). B19V alone did not significantly affect the development of anaemia in a non-anaemic child. Microcytic anaemia was associated with B19V and co-infection with B19V and malaria more than normocytic normochromic anaemia.

CONCLUSIONSB19V was associated with malaria in cases of severe anaemia. The association posed a significant risk for exacerbation of anaemia in mild anaemic children. B19V and co-infection with B19V and malaria may be associated with microcytic anaemia rather than normocytic normochromic anaemia as seen in cases of B19V infection among persons with red cell abnormalities.

OBJECTIVETo summarize and review the clinical characteristics including clinical features, prenatal characteristics, diagnosis, treatments and short-term outcomes of the twin anemia-polycythemia sequence (TAPS) to improve the recognition of the disease.

METHODThe clinical data of one case with twin anemia-polycythemia sequence and the reports of 15 cases seen in the past 5 years were reviewed and analyzed.

RESULTThere was an increasing number of reports of cases with TAPS. Prenatal manifestation: among the 16 cases, TAPS occurred in 13 cases naturally and in 3 cases occurred after laser treatment. Amniotic fluid volume showed no significant difference in 16 cases. Middle cerebral artery peak systolic velocity (MCA-PSV) > 1.5 multiples of the median (MoM) in the donor were 11/16 cases and 3/16 cases were not tested. MCA-PSV < 1.0 MoM in the recipient were seen in 10/16 cases and in 3/16 cases MCA-PSV was not tested. Hydrops fetalis was found in 6/16 cases. Intrauterine intervention: intrauterine blood transfusion was performed in 4/16 cases, fetoscopic laser occlusion of chorioangiopagus vessels was performed in 4/16 cases, umbilical cord occlusion selective feticide was done in 2/16 cases and intrauterine hemodilution in the recipient was performed in 1/16 case. Postnatal manifestation: average hemoglobin concentration in the anemic neonate was 95 g/L and in the polycythemic one was 208 g/L, intertwin Hb difference was > 80 g/L in 10/16 cases and < 80 g/L in 2/16 cases (after intrauterine laser treatment). Intertwin reticulocyte count ratio was > 1.7 in 5/16 cases and < 1.7 in 1/16 case (after intrauterine laser treatment). Postnatal treatment: 9/16 cases of donor had anemia, among them, 6/16 cases were given blood transfusions, 6/16 cases of recipient with hyperviscosity underwent partial exchange transfusions. Neurodevelopmental follow-up during neonatal period was normal in 11/16 cases, in our case, neurodevelopmental follow-up at the corrected gestational age 3 months was normal.

CONCLUSIONTAPS is a new atypical form of twin-twin transfusion syndrome (TTTS) that presents as a large intertwin hemoglobin difference with one twin developing anemia and the other developing polycythemia, without oligohydramnios-polyhydramnios sequence that is required for the diagnosis of TTTS. We suggest that routine doppler studies and MCA-PSV measurements should be performed during each follow-up visit in all uncomplicated monochorionic twin pregnancies, in order to find out the cases required intrauterine intervention to decrease neonatal mortality rates and improve the prognosis.

AIMTo investigate the possible role of rate-limiting enzyme of heme metabolism and globin in the development of the low hemoglobin (Hb), red blood (cell) count (RBC) and hematocrit (Hct) after long-term exercise, and effect of nutrition supplement on sports anemia.

METHODSMale Wistar rats were randomly assigned to three groups (n = 10): control (C), exercise (P) and exercise + nutrition (G). Animals in the P and G groups started treadmill running at 30 m/min, 0% grade, 1 min/time. Running time was gradually increased with 2 min/time during initial 5 weeks and final 4 weeks. In addition, running frequency was 2 times/day except initial 2 weeks. At the end of eleventh week, gene expression of 5-aminolevulinate synthase (ALAS), ferrochelatase, alpha-globin and beta-globin in bone marrow were measured with RT-PCR. Mean-while heme oxygenase 1 (HO-1) activity in liver was measured with immunohistochemical method.

RESULTSEleven weeks of exercise induced a significant increase in HO-1 and a significant increase in gene expression of beta-globin (P < 0.01, P < 0.05, respectively). Treatment with anti-sports anemia compound dosage led to no significant differences in rate-limiting enzyme of heme metabolism and globin in the exercised rats. The G group had a significantly higher HO-1 level in liver than the C group (P < 0.01). These finds showed that exercise was associated with no significant difference in heme synthetase and alpha-globin gene expression, and significant difference in heme catabolic enzyme and beta-globin gene expression.

CONCLUSIONThe increase of HO-1 activity in liver might be one of the causes of the lower Hb, RBC and Hct status in exercised rats.
