Subclinical acute antibody-mediated rejection in positive crossmatch renal allografts.

Subclinical antibody-mediated rejection (AMR) has been described in renal allograft recipients with stable serum creatinine (SCr), however whether this leads to development of chronic allograft nephropathy (CAN) remains unknown. We retrospectively reviewed data from 83 patients who received HLA-incompatible renal allografts following desensitization to remove donor-specific antibodies (DSA). Ten patients had an allograft biopsy showing subclinical AMR [stable SCr, neutrophil margination in peritubular capillaries (PTC), diffuse PTC C4d, positive DSA] during the first year post-transplantation; 3 patients were treated with plasmapheresis and intravenous immunoglobulin. Three patients had a subsequent rise in SCr and an associated biopsy with AMR; 5 others showed diagnostic or possible subclinical AMR on a later protocol biopsy. One graft was lost, while remaining patients have normal or mildly elevated SCr 8-45 months post-transplantation. However, the mean increase in CAN score (cg + ci + ct + cv) from those biopsies showing subclinical AMR to follow-up biopsies 335 +/- 248 (SD) days later was significantly greater (3.5 +/- 2.5 versus 1.0 +/- 2.0, p = 0.01) than that in 24 recipients of HLA-incompatible grafts with no AMR over a similar interval (360 +/- 117 days), suggesting that subclinical AMR may contribute to development of CAN.

Identification of quantitative trait loci (QTL) for oil and protein contents and their relationships with other seed quality traits in Brassica juncea.

A detailed RFLP-genomic map was used to study the genetics of oil, seed and meal protein and sum of oil and seed/meal protein contents in a recombinant doubled-haploid population developed by crossing black- and yellow-seeded Brassica juncea lines. Two yellow seed color genes (SC-B4, SC-A6) and one QTL for erucic acid content (E(1b)) showed pleiotropic effect for oil, protein and sum of oil and seed/meal protein contents. Six (O-A1, O-A6, O-A9, O-B3, O-B4, O-B5) and five (SP-A1, SP-A9, SP-B4, SP-B6, SP-C) QTLs were significant for oil and seed protein contents, respectively. Tight linkage of three of these QTLs (SP-A1, SP-A9, SP-B4, O-A1, O-A9, O-B4), with opposite effects, poses challenge to the plant breeders for simultaneous improvement of negatively correlated (r = -0.7**) oil and seed protein contents. However, one QTL for oil content (O-B3) and two for seed protein content (SP-B6, SP-C) were found to be unlinked, which offer the possibility for simultaneous improvement of these two traits. QTLs significant for meal protein (MP-A1, MP-A6, MP-A9, MP-B5, MP-B6) were significant at least for oil, seed protein or sum of oil and seed/meal protein contents (T-A6, T-A7, T-B4, T-B5). Sum of oil and seed protein contents and sum of oil and meal protein contents had a perfect correlation, as well as same epistatic interactions and QTLs with similar additive effect. This indicates that protein in seed or meal has practically the same meaning for breeding purposes. Epistatic interactions were significant for the quality traits, and their linkage reflected association among the traits.

Association of HLA class I antigen matching and early graft outcome in living donor kidney transplantation.

INTRODUCTION: HLA antigen matching often plays an important role in organ transplantation. As for HLA class I antigen matching, there are differences of opinion regarding its influence on the outcome of renal transplantations. The aim of this study was to evaluate the association of HLA class I antigen matching with early graft outcomes in living donor kidney transplantation. PATIENTS AND METHODS: We evaluated graft outcomes in the first month of transplantation. Major events were slow graft function (serum creatinine > 250 micromol/L at the end of first week), delayed graft function (patients requiring dialysis in first week), and acute rejection episode. Graft outcomes were compared for normal renal function (NRF, serum creatinine < or = 175 micromol/L) impaired renal function (IRF, serum creatinine > 175 micromol/L) or impaired graft function due to an acute rejection episode (IGF). RESULTS: The 115 subjects had a mean age of 29 +/- 8 years and their donors 38 +/- 11 years (P < .01). Immunosuppression included prednisolone, azathioprine, and cyclosporine. Parents, siblings, and others were kidney donors in 46%, 33%, and 21%, respectively. Comparisons between NRF/IRF (serum creatinine 133 +/- 24 vs 201 +/- 36 micromol/L, P < .01) and NGF/IGF (serum creatinine 146 +/- 44 vs 161 +/- 39 micromol/L, P < .05) showed no difference in number or pattern of HLA matching. CONCLUSION: HLA class I antigen matching may not produce an added influence on early graft outcome among living donor kidney transplantations.

Cardiac functional and morphologic changes of renal allograft recipients in the early posttransplant period.

UNLABELLED: After renal transplantation there is a substantial alteration in cardiac morphology and functions. This prospective study was undertaken to observe changes in different cardiac parameters in early months after transplantation. PATIENTS AND METHODS: Twenty-two allograft recipients (primary disease glomerulonephritis) were evaluated in the immediate pretransplant period (0 month) and 1 and 3 months after transplantation by clinical and echocardiographic (M mode, 2D) evaluations. RESULTS: Pretransplant echocardiogram showed left ventricular hypertrophy (LVH) in 100% subjects, LV dilation in 52%, and systolic dysfunction in 18%. By the third month, significant differences in systolic blood pressure (SBP-161 +/- 16 to 133 +/- 26 mm Hg, P < .002); diastolic BP (DBP-101 +/- 9 to 86 +/- 11 mm Hg, P < .006), and hemoglobin level (Hgb-7.3 +/- 1.6 to 11.2 +/- 3.9 g/dL, P < .006) were evident. Echocardiography showed decreased left atrial diameter (LADd-41 +/- 5 to 35 +/- 3 mm, P < .001); left ventricular internal diameter (LVIDd-54 +/- 6 to 47 +/- 6 mm, P < .02); left ventricular muscle mass index (LVMI-379 +/- 114 to 248 +/- 58 g/m(2), P < .001); and left ventricular end diastolic volume index (LVEDVI-96 +/- 28 to 64 +/- 17 ml/m2, P < .002). Bivariate correlations showed positive associations of mean blood pressure (MBP) and serum creatinine with LVMI, LVEDVI, and negative association of hemoglobin with MBP, serum creatinine, LVMI, and LVEDVI. CONCLUSION: From these observations, we concluded that cardiac morphological parameters start improving in the early posttransplant period. Improvements in renal function, anemia status, and lower blood pressure showed strong associations with these changes.

Quantitative detection of promoter hypermethylation as a biomarker of acute kidney injury during transplantation.

Aberrant promoter hypermethylation, also known as epigenetics, is thought to be a promising biomarker approach to diagnose malignancies. Kidney repair after injury is a recapitulation of normal morphogenesis, with similarities to malignant transformation. We hypothesized that changes in urine epigenetics could be a biomarker approach during early kidney transplant injury and repair. We examined urine DNA for aberrant methylation of two gene promoters (DAPK and CALCA) by quantitative methylation-specific polymerase chain reaction from 13 deceased and 10 living donor kidney transplant recipients on postoperative day 2 and 65 healthy controls. Results were compared with clinical outcomes and to results of the kidney biopsy. Transplant recipients were significantly more likely to have aberrant hypermethylation of the CALCA gene promoter in urine than healthy controls (100% vs 31%; P < .0001). There was increased CALCA hypermethylation in the urine of deceased versus living donor transplants (21.60 +/- 12.5 vs 12.19 +/- 4.7; P = .04). Furthermore, there was a trend toward increased aberrant hypermethylation of urine CALCA in patients with biopsy-proven acute tubular necrosis versus acute rejection and slow or prompt graft function (mean: 20.40 +/- 6.9, 13.87 +/- 6.49, 17.17 +/- 13.4; P = .67). However, there was no difference of CALCA hypermethylation in urine of patients with delayed graft function versus those with slow or prompt graft function (16.9 +/- 6.2 vs 18.5 +/- 13.7, respectively; P = .5). There was no aberrant hypermethylation of DAPK in the urine of transplant patients. Urine epigenetics is a promising biomarker approach for acute ischemic injury in transplantation that merits future study.

C4d and C3d staining in biopsies of ABO- and HLA-incompatible renal allografts: correlation with histologic findings.

Biopsies of ABO-incompatible and positive crossmatch (HLA-incompatible) renal allografts were retrospectively examined to compare results of C4d and C3d staining, and the correlation between such staining and histologic findings suggestive of antibody-mediated rejection (AMR). A total of 75 biopsies (55 protocol, 17 for graft dysfunction, 3 for other indications) of 24 ABO-incompatible grafts and 244 biopsies (103 protocol, 129 for graft dysfunction, 12 for other indications) of 66 HLA-incompatible grafts were examined; all were stained for C4d and approximately 40% for C3d. In ABO-incompatible grafts, 80% of protocol biopsies and 59% performed for graft dysfunction showed C4d staining in peritubular capillaries (PTC); this staining was not correlated with neutrophil margination in PTC. In HLA-incompatible grafts, PTC C4d was present in 26% of protocol biopsies and 60% of biopsies for graft dysfunction; 92% of biopsies with >1+ (0-4+ scale), diffuse PTC C4d had > or =1+ margination and/or thrombotic microangiopathy (TMA), compared with 12% of C4d-negative biopsies. C3d was somewhat more predictive of margination than C4d in ABO-incompatible, but not HLA-incompatible, grafts. In summary, while PTC C4d deposition indicates probable AMR in biopsies of HLA-incompatible grafts, including protocol biopsies, there is no histologic evidence that C4d deposition is correlated with injury in most ABO-incompatible grafts.

Vascular change in the placenta of diabetic mothers and hypertensive diabetic mothers.

Pregnancy complicated by diabetes and/or hypertension is a significant medical problem not only affecting maternal health, but also jeopardizing fetal normalcy. The placenta being the bridge between maternal fetal activity, this structure is considered as a window through which understanding of maternal dysfunctions as well as of their impacts on fetal wellbeing can be obtained. And as it is an almost all-vessel organ, its functional status depends primarily on the structural status of its vessels. To observe vascular changes in the placenta, a study was carried out on 44 placentas.19 from overt diabetic mothers having no hypertension and 5 from hypertensive diabetic mothers, and 20 from control group having no hypertension or diabetes. These were collected just after delivery though caesarian section. Macroscopic findings of the study was that there was a trend of increase weight, volume and number of cotyledons in overt diabetes group, where as the in the hypertensive diabetes group was the opposite. But none of these levels has reached a significant level. For all these variables, the hypertensive diabetes group had smaller values than the overt diabetes group, significantly so for the number of cotyledons. The placental diameter was non-significantly larger in the overt diabetes group than in the control group, but a smaller than control value was found in the hypertensive diabetes group. Although neonatal weight did not show any significant change in either group, but in overt diabetes group, it showed a significant positive correlation with placental weight.

Molecular markers for seed colour in Brassica juncea.

A detailed RFLP map was used to map QTLs associated with seed colour in Brassica juncea using a doubled-haploid population derived from a cross between a black/brown-seeded cultivar and a yellow-seeded breeding line. Segregation analysis suggested that seed colour was under control of 2 unlinked loci with duplicate gene action. However, QTL analysis revealed 3 QTLs, SC-B4, SC-A10 and SC-A6, affecting seed colour. The QTLs were consistent across environments, and individually explained 43%, 31%, and 16%, respectively, and collectively 62% of the phenotypic variation in the population. Digenic interaction analysis showed that closest flanking locus of QTL SC-B4, wg7b6cNM, had strong epistasis with the locus wg5a1a, which is tightly linked to QTL SC-A6. The interaction of these 2 loci explained 27% of the phenotypic variation in the population, while the whole model explained 84%. In a multiple regression model, the effects of QTL SC-A10, as well as its interaction with other loci, were non-significant, whereas the effects of loci wg7b6cNM and wg5a1a and their interaction were significant. Ninety-eight percent of the DH lines carried the expected alleles of loci wg7b6cNM and wg5a1a for seed colour, confirming that only these 2 loci were linked to seed colour in B. juncea. Four additional digenic interactions significantly affected seed colour, and all 5 digenic interactions were consistent across environments.

Socio-economic status of chronic arsenicosis patients in Bangladesh.

The study showed that the maximum number of arsenicosis patients (71%) belonged to low income group and 29% belong to middle class income group but none was found in high income group and all these patients were from rural areas of the country. Majority of all these patients was related with the traditional occupation of the country like cultivation (53%) in addition to lower level of educational background (81.5%). Most of the patients of chronic arsenicosis were suffering from malnutrition (91%). The present study which reflects that the vast majority of patients of chronic arsenicosis in the country belonged to low income group, but also to low educational background and individuals, who had been suffering from malnutrition, needs a special consideration in the management of the problem. Emphasis has been given to have access to arsenic-free water and protein rich diet to people of arsenic affected areas.

Placebo controlled trial of methotrexate in systemic sclerosis.

Eighteen adult patients of systemic sclerosis were included in this prospective study from Rheumatology Clinic of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka during the period of July 1997 to December 1999 to observe the effectiveness of treatment with methotrexate (MTX) versus placebo. Among the eighteen patients 9 patients were randomly assigned to MTX and 9 to placebo therapy. Nine patients were dropped out (6 in placebo and 3 in the MTX group), because of toxicity and non-compliance. Clinical improvement following treatment was observed in 33.33% of the patient in MTX group but none in placebo group, but this difference was not statistically significant. Anorexia, nausea and occasional vomiting were common side effects in MTX group and subsided in most cases with the passage of time despite the continuation of therapy.

Correlation of serum parathormone level with biochemical parameters in chronic renal failure.

A prospective study was carried out to assay the level of serum intact parathormone and its correlation with biochemical parameters in patients with chronic renal failure (CRF). The study included 64 children (44 with CRF, and 20 age and sex matched controls). Serum intact parathormone (iPTH), serum creatinine, urea, calcium, inorganic phosphate and alkaline phosphatase were estimated. Creatinine clearance (Ccr) was estimated by Schwartz formula. Patients with CRF were divided into four groups based on their Ccr (mild CRF with mean Ccr 59.17 +/- 1:18.53 mL/min/1.73 m2 (n = 6) moderate CRF with mean Ccr 34.98 +/- 7.75 mL/min/1.73 m2 (n = 7); severe CRF with mean Ccr 17.71 +/- 5.40 mL/min/1.73 m2 (n = 15); and end-stage renal disease with mean Ccr 6.46 +/- 1.71 mL/min/1.73 m2 (n = 16). Mean serum iPTH levels were 93.00 +/- 46.62 pg/mL in CRF and 16.52 +/- 9.35 pg/mL in controls. Groupwise mean serum (iPTH) levels were 48.50 +/- 4.76, 67.29 +/- 7.91, 82.42 +/- 9.67 and 130.66 +/- 58.74 pg/mL in mild, moderate, severe CRF and endstage renal failure respectively. Mean serum iPTH level of CRF (93.00 +/- 46.42 pg/mL) negatively correlated with mean Ccr (22.02 +/- 18.53 mL/min/l.73 m2) (P < 0.001) and mean serum calcium (7.30 +/- 1.02 mg/dL) (P < 0.001) and positively correlated with mean inorganic phosphate (5.76 +/- 1.1 mg/dL) (P < 0.05) and mean alkaline phosphatase (355.14 +/- 185.53 UL) (P < 0.001). We conclude that increased iPTH level occur even early in the course of CRF and progressive hypocalcemia and hyperphosphatemia are the initiating factors for the development of hyperparathyroidism.

Chronic renal failure in children.

The study was carried out to see the etiology and outcome of chronic renal failure in children. It is a prospective study, carried out to evaluate all new cases of CRF in children < 15 years in nephrology unit of BSMMU from May 2000 to May 2002. Diagnosis of CRF was based on Ccr < 75 ml/min/m(2) along with other features of CRF with no evidence of recovery over ensuing three months. A total of 44 children with CRF having mean age of 8.73 3.56 years were diagnosed during study period, among them, 30 cases (68.19%) were male and 14 cases (31.81%) were female. Causes of CRF were obstructive uropathy in 24 cases (54.55%) followed by glomerular diseases in 15 cases (34.9%), hereditary disorders in 3 cases (6.81%), and reflux nephropathy in 2 cases (4.54%). At presentation, 13 (29.55%) children had mild to moderate CRF and 31 (70.45%) children had severe CRF and ESRD. Mean follow up period was 32.3 weeks. At the end of the study period, 8 patients of mild to moderate CRF were on conservative treatment, 6 patients of severe CRF and ESRD group attended for maintenance dialysis irregularly of which 3 died at hospital and rest of the patients did not attend at follow up due to financial reason or opted against IPD. In the present study, majority of the children with CRF is due to treatable obstructive uropathy; mostly PUV and most of them presented with advanced renal disease.

Competitive binding of ibuprofen and naproxen to bovine serum albumin : modified form of drug-drug displacement interaction at the binding site.

The competitive binding characteristics of ibuprofen and naproxen with respect to binding site on bovine serum albumin (BSA) was studied by equilibrium dialysis method at pH 7.4 and 25 degrees C. We studied the effect of one drug on the free concentration of another in vitro during concurrent administration. There was remarkable increase in free concentration of naproxen when ibuprofen (2x10(-5) M) was added to a 1:1 naproxen-BSA mixture (2x10(-5) M: 2x10(-5) M), suggesting that ibuprofen displaced naproxen from its binding sites. However free fraction of naproxen was not increased up to the level expected from direct competitive displacement. Free concentration of ibuprofen was hardly increased by naproxen when naproxen (2x10(-5) M) was added to the ibuprofen-BSA (1:1) mixture. But in both cases, in presence of ranitidine (site I specific probe), the free concentration of the displaced drug increased more prominently compared to that in absence of ranitidine. This result suggests that, ibuprofen displaces naproxen and vice versa from its high affinity binding site (site II) and the displaced drug rebounds to its low affinity binding site (site I) on BSA molecule. This form of modified displacement has been arbitrarily referred to as site-to-site displacement.

Obstetric deaths in Bangladesh, 1996-1997.

OBJECTIVES: The purpose of this study was to measure and to describe obstetric deaths in Bangladesh. METHODS: We reviewed hospital records and interviewed health workers in clinic sites and field workers who cared for pregnant women. RESULTS: We obtained case reports of 28998 deaths of women aged 10-50, of which 8562 (29.5%) were maternal deaths. Most (7086, 82.8%) of these deaths were due to obstetric causes. The most common causes of direct obstetric death were eclampsia (34.3%), hemorrhage (27.9%), and obstructed and/or prolonged labor (11.3%). National direct obstetric death rate was estimated to be 16.9 per 100,000 women. CONCLUSIONS: Efforts to reduce fertility in Bangladesh have led to an estimated 49% reduction in the maternal mortality rate per 1000 women during the past 18 years. Variations in maternal mortality suggest the need to develop local strategies to improve obstetric care.

Isolation, characterization, inheritance and linkage of microsatellite DNA markers in white spruce (Picea glauca) and their usefulness in other spruce species.

Microsatellite DNA/simple-sequence-repeat (SSR) loci were identified, isolated and characterized in white spruce (Picea glauca) by screening both a non-enriched partial genomic library and a partial genomic library enriched for (AG/TC)n-containing clones. Inheritance and linkage of polymorphic SSR loci were determined in F1 progeny of four controlled crosses. We also assessed the compatibility and usefulness of the P. glauca microsatellite DNA markers in five other Picea species. Twenty-four microsatellites were identified by sequencing 32 clones selected from screens of 5,400 clones from the two libraries. The (AG/TC)n microsatellites were the most abundant in the non-enriched library. Eight microsatellite DNA loci were of the single-copy type, and six of these were polymorphic. A total of 87 alleles were detected at the six polymorphic SSR loci in 32 P. glauca individuals drawn from several populations. The number of alleles found at these six SSR loci ranged from 2 to 22, with an average of 14.5 alleles per locus, and the observed heterozygosity ranged from 0.48 to 0.91, with a mean of 0.66 per locus. Parents of the controlled crosses were polymorphic for five of the six polymorphic SSR loci. Microsatellite DNA variants at each of these five SSR loci followed a single-locus, codominant, Mendelian inheritance pattern. Joint two-locus segregation tests indicated complete linkage between PGL13 and PGL14, and no linkage between any of the remaining SSR loci. Each of the 32 P. glauca individuals examined had unique single or two-locus genotypes. With the exception of non-amplification of PGL12 in P. sitchensis, P. mariana, and P. abies and the monomorphic nature of PGL7 in P. mariana, primer pairs for all six polymorphic SSR loci successfully amplified specific fragments from genomic DNA and resolved polymorphic microsatellites of comparable sizes in P. engelmanni, P. sitchensis, P. mariana, P. rubens, and P. abies. The closely related species P. mariana and P. rubens, and P. glauca and P. sitchensiss could be distinguished by the PGL12 SSR marker. The microsatellite DNA markers developed and reported here could be used for assisting various genetics, breeding, biotechnology, tree forensics, genome mapping, conservation, restoration, and sustainable forest management programs in spruce species.

Formation of viable but non-culturable state (VBNC) of Aeromonas hydrophila and its virulence in goldfish, Carassius auratus.

In this study we investigated the viable but non-culturable (VBNC) state of Aeromonas hydrophila and its virulence in goldfish. Aeromonas hydrophila cultured in a 0.35% NaCl solution at pH 7.5 and at 25 degrees C for 50 days showed the VBNC state. In the VBNC state we were unable to detect viable bacteria by the plate count method but we did find 10(4) cells/ml by the direct viable count microscopical method after staining with fluorescein diacetate and ethidium bromide. The virulence comparison in goldfish showed that bacteria cultured at 25 degrees C for 1 day in a 0.35% NaCl solution were more virulent than bacteria cultured for 28 days. VBNC bacteria showed lower virulence in goldfish compared to 28-day-cultured bacteria by intraperitoneal injection. The results from the study suggest that A. hydrophila can remain in the aquatic environment for prolonged periods in the VBNC state but those cells are not pathogenic to goldfish.

Circular dichroism simulation shows a site-II-to-site-I displacement of human serum albumin-bound diclofenac by ibuprofen.

PURPOSE: The purpose of this study was to confirm the hypothesis that a site-II-to-site-I displacement takes place when some nonsteroidal anti-inflammatory drugs are displaced by another drug from their high-affinity binding site to a site of lower affinity on human serum albumin (HSA). METHODS: Diclofenac, sodium salt, was used as a representative example because of its prominent reversal of the Cotton effect. Effects of site-specific drugs on the free fraction of diclofenac were determined by equilibrium dialysis, and effects on induced circular dichroism (CD) of diclofenac bound to HSA were studied by CD and CD simulation techniques. RESULTS: Ibuprofen, a site-II-specific drug, altered the CD spectrum of the diclofenac-HSA complex at a molar ratio of 0.5 : 1 to that obtained at a higher ratio (5:1) without ibuprofen. The induced CD spectrum obtained in the presence of ibuprofen was very similar to one that assumed that all diclofenac displaced from its high-affinity binding site (site II) became rebound to a lower-affinity site (site I). The rebinding could be influenced by a free energy linkage between the two sites which would make site I (or parts thereof) more suitable for diclofenac binding. CONCLUSION: We have confirmed the existence of a site II-to-site I displacement, which is very striking and pharmacologically important, because the concentration of unbound drug being displaced is much lower than expected for a competitive mechanism.

Injury-related deaths among women aged 10-50 years in Bangladesh, 1996-97.

BACKGROUND: Few studies have examined injury-related deaths among women in Bangladesh. We did a case-finding study to identify causes and the impact of intentional and unintentional injury-related deaths among women aged 10-50 years in Bangladesh. METHODS: Between 1996 and 1997, health care and other service providers at 4751 health facilities throughout Bangladesh were interviewed about their knowledge of deaths among women aged 10-50 years. In addition, at all public facilities providing inpatient service, medical records of women who died during the study period were reviewed. The reported circumstances surrounding each death were carefully reviewed to attribute the most likely cause of death. FINDINGS: 28,998 deaths among women aged 10-50 years were identified in our study, and, of these, 6610 (23%) were thought to be caused by intentional or unintentional injuries. About half (3317) of the injury deaths were attributable to suicide, 352 (5%) to homicide, 1100 (17%) to accidental injuries, and the intent was unknown for 1841 (28%) deaths. The unadjusted rate of suicides were higher in the Khulna administrative division (27.0 per 100,000) than the other four administrative divisions of Bangladesh (range 3.5-11.3 per 100,000). Poisoning (n=3971) was the commonest cause of injury-related death--60% of all injury deaths (6610) and 14% of all deaths (28,998). Other common causes of injury deaths in order of frequency were hanging or suffocation, road traffic accidents, burns, drowning, physical assault, firearm or sharp instrument injury, and snake or animal bite. INTERPRETATION: Intentional and unintentional injuries are a major cause of death among women aged 10-50 years in Bangladesh. Strategies to reduce injury-related deaths among women need to be devised.
