In 2005, four dual-purpose, promiscuous soybean varieties （cv. TGx1440-IE; TG×1448-2E; TG×1019-2EB; and TG×1844-18E）, and a popular improved variety （cv. Jupiter） were sown in 12 farmer fields with and without Bradyrhizobium japonicum inoculation. There was also land which was left fallow that acted as the control. In 2006, upland interspecific rice （NERICA 1） was sown in all the plots and supplied with 15 kg N haL. Dry matter yield, N accumulation, and net N-balance were significantly enhanced by over 40% with inoculation of cv. TG× 1844-18E than non-inoculation in the DS in comparison to other cultivars. There were no significant effects of inoculation of previous soybean cultivars on soybean grain yield and on the succeeding NERICA rice yield. Averaged over inoculation, previous cv. TG× 1019-2EB plots supplied with only 15 kg N hal gave the highest grain yield, more than twice the yield of control plots in the DS, possibly because of significant production of higher tillers, panicles and harvest index than the other cultivars; and it could be recommended for upland rice-based system for NERICA production.展开更多

However, in some cases the clinical symptoms is not typical and nephropathy may be different from diabetic and require the use of renal biopsy (RB) which is not usually indicated unless non-diabetic nephropathy (NND) is suspected. The objective of this study was to evaluate the prevalence of non-diabetic nephropathy (NDN) among the diabetic patients and to analyse the different predictive factors of its occurrence. Patients and methods: It was a retrospective, descriptive and analytical study which is carried out at the nephrology department of Aristide Le DANTEC hospital of Dakar over a period of 60 months. Diabetics with suspected NDN diagnosis based on renal anomalie that is associated with a recent diabetes, Acute renal failure with rapid progress, Diabetic retinopathy’s absence, and Extrarenal signs (cutaneous, digestive and articular) associated with an acute renal failure. Microscopic haematuria was included. The epidemiological, clinical, biological and histological parameters were collected and analysed using the SPSS, 3.5 version software. Results: Out of 34 biopsied diabetic patients, 12 had NDN that is a prevalence of 35, 3%. The average age was 49.88 ± 4.15 years, 0.78 for the sex-ratio and the mean duration of diabetes is 12.53 ± 4.7 years. Glomerular syndrome was found in 30 patients (88.23%), vascular nephropathy syndrome in 3 patients (8.82%) and tubule-interstitial nephropathy syndrome in only one patient (2.94%). Diabetic retinopathy (DR) and microscopic haematuria (HU) respectively existed in 10 patients (34%) and 15 patients (44. 12%). The Kidney biopsy (KB) indications were renal abnormalities associated with recent diabetes, acute renal failure with rapid progress, absence of DR, extrarenal signs associated with acute renal failure and microscopic haematuria. Twenty-two patients (64.7%) had diabetic nephropathy (DN) and 12 patients (38.2%) presented a NDN. Predictive factors of NDN diagnosis were a shorter diabetes duration (P = 0.0008), high blood pressure (P = 0.0015) and absence of DR (P = 0.005). Conclusion: Our data show that kidney injury in a diabetic is not always diabetic nephropathy. The Kidney biopsy (KB) is often needed in order to adopt an effective management.展开更多

The objective of our study was to assess our practice in this lesion. <strong>Patients and Methods:</strong> We carried out a retrospective study of patients treated for primary FSGS the period January 1, 2010 to September 30, 2018. The clinical pathological, therapeutic and evolutive characteristics were studied. <strong>Results:</strong> Fifty-eight patients were included in the study. The average age was 30.74 ± 11.35 years and the sex ratio (M/F) was 2.41. Edema was found in 86.2% and hypertension in 37.9%. The average creatinine was 20.17 ± 16.06 mg/l and the average GFR according to MDRD was 82.43 ± 69.06 ml/min/1.73 m2. The average albumin level was 15.11 ± 5.78 g/l and the 24-hour proteinuria was 7.8 ± 3.79 g/24 h. Nephrotic syndrome was the main indication for renal biopsy in 84.48% and the classic form of FSGS was found in 90.9%. The average initial corticosteroid dose was 62.68 ± 10.04 mg/d and the average duration of regression was 11.78 ± 7.40 months. Forty-five patients (77.6%) were corticosensitive (27.6% complete remission and 50% partial remission). Corticosteroid resistance was observed in 19% and corticosteroid dependence in 11.1%. The proportion of relapse was 33.3% within an average of 15.4 ± 9.1 months. Cyclosporine was no longer prescribed as a second-line treatment in 8 patients. Infectious complications were more found in 19%. Two patients had progressed to ESRD and we noted 2 death cases. The male gender was correlated with the occurrence of a relapse. However, the impact of certain factors such as hypertension, proteinuria, hematuria and GFR level has not been demonstrated. <strong>Conclusion:</strong> The evolution of primary FSGS is unpredictable, often marked by relapses, hence the interest in identifying factors associated with therapeutic responses for better management.展开更多
