RESUMEN

INTRODUCTION: Most patients with hypertension in sub-Saharan Africa require two or more drugs to control their blood pressure. Triple fixed-dose combination therapy of perindopril arginine/indapamide/amlodipine is more effective in lowering blood pressure, offers better target organ protection and has increased adherence compared to monotherapy and free combination therapy, and is safe to use. This observational study evaluates the effectiveness of perindopril arginine/indapamide/amlodipine in controlling blood pressure at least 1 month after treatment initiation and assesses patient- and physician- reported drug tolerance over a 3-month period in Madagascar and Mauritius. METHODS: A total of 198 patients with hypertension in ambulatory care who had been on fixed-dose combination of perindopril arginine, indapamide, and amlodipine for at least 4 weeks were included. The main outcome measures were changes in systolic and diastolic blood pressure, attainment of blood pressure control under 140/90 mmHg and 130/80 mmHg, self-reported drug tolerance by the patient, and perceived drug tolerance by the treating physician. Data was collected at 1 month and 3 months. RESULTS: Mean systolic blood pressure was significantly lower at the 1-month (- 3.4 mmHg, p = 0.002) and 3-month (- 8.5 mmHg, p < 0.0001) visits. Diastolic blood pressure also decreased significantly (- 2.4 mmHg at 1-month, p = 0.017 and - 5.4 mmHg at the 3-month visits, p < 0.0001). At 3 months, 80.4% of the patients attained blood pressure targets less than 140/90 mmHg and 42.7% attained targets less than 130/80 mmHg on the basis of their baseline blood pressure. Excellent drug tolerance was reported by more than 90% of patients and physicians at the 1-month visit and by more than 95% at the 3-month visit. CONCLUSION: Triple fixed-dose therapy of perindopril arginine/indapamide/amlodipine continues to show additional blood pressure-lowering capacity even months after initiating the treatment in patients with hypertension in Madagascar and Mauritius. It is also well tolerated by patients with hypertension and assessed as safe to use by physicians.

RESUMEN

INTRODUCTION: Chronic kidney disease is defined as an inability of the kidney to perform its normal functions and which persists beyond three months. Nowadays, the estimated glomerular filtration rate based on plasmatic creatinine level remains the gold standard to assess renal function. In Madagascar, we miss national data concerning the epidemiology of chronic kidney disease probably due to the complexity of carrying out the serum creatinine assays. The recent availability of creatinometer using a creatinine strip test with capillary creatinine facilitated the determination of the creatinine level in epidemiological study. PATIENTS AND METHODS: This simple technique allowed us to plan a pilot study in Antananarivo, the capital of Madagascar. The main objective was to assess the prevalence of chronic kidney disease determined from capillary creatinine level. The secondary objective was to determine the factors associated with chronic kidney disease in Madagascar. It is an analytical cross-sectional study over a period of three months. Chronic kidney disease is defined as a decrease of the glomerular filtration rate of capillary creatinine less than 60mL/min/1.73m2 and calculated with Chronic Kidney Disease Epidemiology formula (CKD-EPI). The minimum number of studied population has been assessed and settled at 210 people. Cluster sampling was performed for randomization of participants. RESULTS: At the end of the study, 210 people were randomized for screening. The average age was 40 years old with 14.9 as standard deviation. The sex ratio (male/female) was 1.76. The prevalence of chronic kidney disease was 13.8% with extreme values of 9,1 and 18.5. With chronic kidney disease, high blood pressure (hypertension) and diabetes were found respectively in 41.3 and 17.2%. Chronic kidney disease affected mainly in 72.4% of population aged 25 to 54 years old. CONCLUSION: This is the first study in Africa to screen chronic kidney disease using a creatinine strip test. This prevalence is relatively different compared to other African countries. The limits of the study are the absence of a subsequent control and/or double control of the creatinine, which definitively confirms the chronicity of kidney disease, the absence evaluation of the urinary sediments to determine proteinuria. Nevertheless, the results of our study can be used as data awaiting the results of a multicenter studies. To determine the national prevalence of chronic kidney disease, screening in the six provinces is currently in progress.

RESUMEN

INTRODUCTION: Acute Kidney Injury (AKI) is one of the criteria for severe malaria with a varied incidence. Our objectives are to determine the prevalence of malaria-associated AKI and to report the characteristics of patients with the evolution of cases. PATIENTS AND METHOD: This is a 5-year retrospective descriptive study from January 1, 2015 to December 31, 2019 in the Infectious Diseases department of the University Hospital Center of Befelatanana Antananarivo. Among 379 patients diagnosed, 103 patients (27,18%) with associated AKI were included. We used the criteria of Kidney Disease Improving Global Outcomes group to define AKI. RESULTS: The prevalence of AKI was 27.18%. The mean age of patients was 34.92 years and the sex-ratio was 3.68. Plasmodium falciparum was the causative agent in 98.06% of cases followed by Plasmodium vivax. Diuresis was preserved in 69.86% of cases. Jaundice was the main sign of severity associated (49.51%). The mean creatinine level was 466.93µmol/L. The evolution was favorable under antimalarial drug and rehydration. Dialysis was required in 25.24% of cases. Thirteen patients had died, a rate of 12.62%, of which 8 patients (61.54%) had dialysis criteria but had not been purged for economic reasons. CONCLUSION: AKI is a frequent complication of malaria. It is responsible for significant mortality despite improved care in the fight against malaria.

RESUMEN

Chronic renal failure is a global public health problem. In developed countries, this disease occurs mainly in the elderly, but in Africa it rather affects active young subjects. This disease need for expensive treatments in a low income country, because of its costs. Our aim is to describe the epidemiology of new cases of chronic renal failure in Madagascar. This is a retrospective, descriptive study of 239 patients with chronic renal failure over a 3 year period, starting from 1 January 2007 to 31 December 2009, in the Department of Internal Medicine and Nephrology at University Hospital of Antananarivo. The incidence was 8.51% among patients hospitalized in the Department. The average age of patients was 45.4 years with extremes of 16 and 82 years and a sex ratio 1,46. The main antecedent was arterial hypertension (59.8%). Chronic renal failure was terminal in 75.31% of the cases (n=180). The causes of chronic renal failure were dominated by chronic glomerulonephritis (40.1%), nephroangiosclerosis (35.5%). Hemodialysis was performed in 3 patients (1.26%), no patient was scheduled for a renal transplantation. Mortality rate in the Department was 28.87%. Chronic renal failure is a debilitating disease with a dreadful prognosis which affects young patients in Madagascar. Its treatment remains inaccessible to the majority of patients. The focus must be mainly on prevention, especially on early effective management of infections, arterial hypertension and diabetes to reduce its negative impacts on the community and public health. The project on renal transplantation: living donor, effective and less expensive treatment compared to hemodialysis could also be a good solution for these Malagasy young subjects.
