A survey on lymphocyte T CD3, CD4 and CD8 in peripheral blood of kidney transplant recipients using mycophenolic acid

Introduction: Immunological monitoring could indirectly measure the suppressive effects of the drugs and provide early guidance on necessary preventive interventions in transplant recipients. Objectives: Our goal was to determine whether mycophenolic acid (MPA) modulates peripheral blood lymphocyte T in kidney transplant recipients. Patients and Methods: We assessed T lymphocytes CD3, CD4 and CD8 in peripheral blood in 30 donors and 35 recipients one day before and 10 days after transplantation using Becton Dickinson’s direct immune fluorescent light. Results: Comparisons showed that the number of T lymphocytes CD3+, CD4+, CD8+ in peripheral blood of transplant recipients were lower than donors (TCD3 was 1690.31±503.45 versus 2280.73± 522.48; TCD4 was 549.51 ±211.72 cell/µL versus 766.37± 341.72 cell/µL and CD8 was 1134.37 ±431.07 cell/µL versus 1523.4± 349.23 cell/µL with P<0.001; P=0.001 and P= 0.0002 respectively). Additionally, post-transplantation lymphocytes TCD4 decreased in 10/35 of recipients and increased in 22/35 of recipients (P=0.036). Conclusion: The T lymphocytes CD3, CD4 and CD8 in peripheral blood should be monitored at multiple post-transplant times to make early predictions of transplant rejection during follow-up treatment.

Kidney ultrasound biometric data dynamics in women with gestational hypertension

Introduction: The stable level of morbidity in the Russian Federation of pregnant women with gestational arterial hypertension (GAH) and as a consequence of the disability of women of working age and their offspring actualizes the search for early ultrasound markers of kidney damage as a target organ urgent. Objectives: Despite the variety of publications on ultrasound semiotics of the kidneys, there are no specific biometric parameters of the kidneys in pregnant women without somatic pathology, which actualizes this study. Patients and Methods: A comprehensive clinical examination of 183 outpatients and inpatients (mean age 27.9 ± 4.7 years) with gestational hypertension performed. Results: There is a significant increase in the volume of the right kidney, the left kidney shape index, the diameter of the renal calyces and pelvis, the coefficient of asymmetry, the ratio of the diameter of the renal calyces to the volume of the right kidney with an increase in the degree of gestational hypertension. Conclusion: Structural changes of kidneys are interconnected with hemodynamic parameters observed and can be expressed by mathematical model.

Beneficial effects of Terminalia phillyreifolia (Van Heurck & Müll.Arg.) Gere & Boatwr. bark extract in streptozotocin induced hyperglycaemia and diabetic nephropathy in rats

Introduction: Renal damage is a common clinical manifestation in diabetic patients. Therefore, nephroprotective effect is a desirable property for an antidiabetic agent. Natural compounds belonging to Terminalia phillyreifolia (TP) owing to their potent antioxidant and anti-inflammatory activity may prove to be such agents. Objectives: The objectives of the present study were to evaluate methanolic extract of TP bark for its antihyperglycemic, antioxidant and nephroprotective effect in streptozotocin (STZ) induced diabetes mellitus and nephropathy in rats. Materials and Methods: Diabetic male Wistar rats were divided into five groups; namely, normal control, disease control, standard (NPH insulin, subcutaneously), BE100 (bark extract 100 mg/kg, p.o.) and BE300 (bark extract 300 mg/kg, orally). Treatment was continued for 8 weeks. Plasma glucose levels, oxidative stress parameters, serum creatinine levels, blood urea nitrogen (BUN) levels, per day urine output, urinary protein excretion (UPE) and kidney hypertrophy index were determined at appropriate time points. Results: Untreated animals developed severe hyperglycemia and major disturbance in renal function. Rats in standard and BE treated groups had significantly lower plasma glucose levels and oxidative stress markers as compared to disease control animals. BE rats also exhibited nearly normal urine volumes indicating better glomerular filtration rate. They had lower urinary protein, serum creatinine, BUN levels and lower renal hypertrophy index as compared to untreated animals. Conclusion: TP Bark extract corrected the hyperglycaemia and exerted protective effect against diabetes induced renal damage in rats, which may be partly due to its anti-oxidant effect. Therefore, TP extract can be further evaluated as potential antidiabetic therapy

Urinary risk factors for calcium oxalate urolithiasis in children with monosymptomatic enuresis

Introduction: A disturbed calcium-phosphate balance is an important issue for kidney stone formation in nephrolithiasis. Hypercalciuria (HC) has been proposed as an essential etiology of monosymptomatic nocturnal enuresis (MNE). Objectives: We may suspect that patients with MNE may be at risk of stone formation hence the objective of this paper was to assess the risk in MNE children using Bonn Risk Index (BRI). Patients and Methods: The urinary work-up of 204 children (83 with MNE and 121 controls) included urinary calcium (Ca), magnesium (Mg) and sodium (Na) excretion, Ca/creatinine ratio, BRI, ionized calcium (Ca2+), Mg/creatinine and Ca/citrate ratios, urinary citrates and oxalates (Ox). Results: Ca/creatinine and Mg/creat ratios were higher in the MNE group. There were no differences in Mg and Ca amount in urine and Mg/Ca ratio between MNE and the reference group. Both groups differed in Mg and Ca excretion per kg of body mass. MNE children differed from controls regarding BRI, Ox and urinary Ca2+. No differences in urinary citrate excretion nor Ca/citrate ratio between MNE and the controls were found. Correlations between factors important in the crystallization process in MNE children were recorded. Conclusion: MNE patients may be at risk of oxalate nephrolithiasis. Further studies to assess the role of the BRI and Ca/citrate ratio in predicting stone formation in MNE children are needed.
