Secondary hyperparathyroidism (SHPT) is a common complication of end-stage renal disease. Surgical management occurs in severe forms and/or unresponsive medical treatment. The aim of this study was to outline the indications of parathyroidectomy and its evolution after surgical approach. It was a five-year multicenter backward study in Otorhinolaryngology Department of Fann Hospital and four dialysis centers in Dakar. We include all patients with SHPT who underwent surgery. Preoperative clinical and paraclinical parameters, clinical-biological evolution, and histology findings of the resected parathyroid specimen were collected. Out of 58 patients with hyperparathyroidism, 18 patients required parathyroidectomy, corresponding to a prevalence of 31%. Mean age of patients was 46.6 ± 15.29 years and sex ratio 0.61. Mean duration on dialysis was 44.4 ± 30 months. Ten patients (55.56%) had bone pain and nine patients (50%) had joint pain. Mean serum calcium was 97.27 ± 8.66 mg/L. Mean blood phosphorus levels were 40.47 ± 9.99 mg/L. Mean iPTH rate was 1493.22 ± 1014.93 ng/mL, with a maximum of 5000 ng/mL (77N). Mean value of 25-OH Vitamin D was 32.89 ± 16.02 ng/mL. Parathyroidectomy was indicated after failure of medical treatment with persistence of a serum intact parathyroid hormone concentration above 800 μg/mL in all patients. Subtotal parathyroidectomy (7/8) was performed in 11 patients (61.1%). Two patients (11.11%) benefited from a selective parathyroidectomy (3/4). Evolution was favorable for 13 patients, corresponding to a success rate of 72.2%. It was unfavorable in five patients including one patient with hypoparathyroidism and four patients with recurrent hyperparathyroidism. Surgery for patients with renal hyperparathyroidism in the era of calcimimetics continues to play an important role in selected patients and achieves efficient control of hyperparathyroidism in developing countries.

Introduction: The evolution of primary FSGS is often marked by the occurrence of relapse and corticosteroid resistance and the therapeutic options are numerous and have limited effectiveness. The objective of our study was to assess our practice in this lesion. Patients and Methods: 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. Results: 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. Conclusion: The evolution of primary FSGS is unpredictable, often marked by relapses, hence the interest in identifying factors associated with therapeutic responses for better management.

Background and Aims The lethality and cost of chronic kidney disease (CKD) management are high in Senegal. The aim of this study was to evaluate the access in dialysis at Senegalese public’s hospitals. Method This was a retrospective cohort during 4 years (2014-2018) from the hemodialysis registry waiting list at Aristide Le Dantec University Hospital. This registry is composed by: a registration form (social survey and doctor's visa); a written letter addressed to hospital director and the national identity card. From this registry, telephone calls were made to collect data relating to mortality and access to dialysis. Results seven hundred fifty-one (751) files were collected. The mean age of the patients was 48.12 ± 15.28 years with a sex ratio of 1.02. The socioeconomic level was low in 85.40% (521/610) and average in 13.61% (83/610). The geographic origin was rural in 11.15%, semi-urban in 07.54% and urban in 81.31%. Ten patients (1.64%) had medical care coverage. On call, 49.70% (373/751) were died before accessing to public dialysis, 29.70% (223/751) had accessed public dialysis and 04.00% (30/751) didn’t yet need dialysis. Hundred twenty-one (16.10%) were unreachable and 0.50% (4/751) was unknown. Conclusion The lethality of CKD was high. Access to dialysis in public hospital remains problematic in Senegal despite its democratization. Additional efforts are needed for effective management of all patients at dialysis stage.

Les calcifications metastatiques representent une complication parfois severe de l´insuffisance renale chronique terminale. Leurs consequences cardiovasculaires ont ete associees a l´augmentation de la morbi-mortalite. Nous rapportons l´observation d´une malade presentant une hyperparathyroidie tertiaire complique de calcifications cardiovasculaires dont l´evolution a ete fatale conduisant au deces de la patiente. La prevention constitue la meilleure arme therapeutique et la parathyroidectomie (PTX) pourrait utiliser comme traitement de sauvetage.
